The Use of Project Management to Provide Technological Sovereig

The most important factors, which stipulate the development of any state, are the level of technological independence and availability of sustainable competitive advantages in innovation sphere. Achievement of technological sovereignty in the Russian Federation is a priority task, whose topicality in conditions of unprecedented sanctions pressure is self-evident. In the research the authors analyzed works by home and overseas experts in the field of technological sovereignty and described the problem of possible damage to ecology and human life in the process of developing the technological sphere. Proceed from it the authors put forward an assumption about the necessity of complex approach to reaching the level of critical and end-to-end technologies with regard to goals of sustainable development on the basis of project management. Findings of the research show that there is a certain mutual conformity of goals of sustainable development and national projects being implemented. However, today we have not got projects, whose goals combine achievements of technological independence and principles of sustainable development of the country. The article provides a conceptual scheme of project management use elaborated by the authors. Academic novelty of the scheme is demonstrated by complementarity of specific goals of technological sovereignty and principles of sustainable development.

Induction-concurrent chemoradiotherapy with or without sintilimab in patients with locoregionally advanced nasopharyngeal carcinoma in China (CONTINUUM): a multicentre, open-label, parallel-group, randomised, controlled, phase 3 trial

Anti-PD-1 therapy and chemotherapy is a recommended first-line treatment for recurrent or metastatic nasopharyngeal carcinoma, but the role of PD-1 blockade remains unknown in patients with locoregionally advanced nasopharyngeal carcinoma. We assessed the addition of sintilimab, a PD-1 inhibitor, to standard chemoradiotherapy in this patient population. This multicentre, open-label, parallel-group, randomised, controlled, phase 3 trial was conducted at nine hospitals in China. Adults aged 18-65 years with newly diagnosed high-risk non-metastatic stage III-IVa locoregionally advanced nasopharyngeal carcinoma (excluding T3-4N0 and T3N1) were eligible. Patients were randomly assigned (1:1) using blocks of four to receive gemcitabine and cisplatin induction chemotherapy followed by concurrent cisplatin radiotherapy (standard therapy group) or standard therapy with 200 mg sintilimab intravenously once every 3 weeks for 12 cycles (comprising three induction, three concurrent, and six adjuvant cycles to radiotherapy; sintilimab group). The primary endpoint was event-free survival from randomisation to disease recurrence (locoregional or distant) or death from any cause in the intention-to-treat population. Secondary endpoints included adverse events. This trial is registered with ClinicalTrials.gov (NCT03700476) and is now completed; follow-up is ongoing. Between Dec 21, 2018, and March 31, 2020, 425 patients were enrolled and randomly assigned to the sintilimab (n=210) or standard therapy groups (n=215). At median follow-up of 41·9 months (IQR 38·0-44·8; 389 alive at primary data cutoff [Feb 28, 2023] and 366 [94%] had at least 36 months of follow-up), event-free survival was higher in the sintilimab group compared with the standard therapy group (36-month rates 86% [95% CI 81-90] vs 76% [70-81]; stratified hazard ratio 0·59 [0·38-0·92]; p=0·019). Grade 3-4 adverse events occurred in 155 (74%) in the sintilimab group versus 140 (65%) in the standard therapy group, with the most common being stomatitis (68 [33%] vs 64 [30%]), leukopenia (54 [26%] vs 48 [22%]), and neutropenia (50 [24%] vs 46 [21%]). Two (1%) patients died in the sintilimab group (both considered to be immune-related) and one (<1%) in the standard therapy group. Grade 3-4 immune-related adverse events occurred in 20 (10%) patients in the sintilimab group. Addition of sintilimab to chemoradiotherapy improved event-free survival, albeit with higher but manageable adverse events. Longer follow-up is necessary to determine whether this regimen can be considered as the standard of care for patients with high-risk locoregionally advanced nasopharyngeal carcinoma.

Summary of Outpatient Visits for Characteristic Nursing in Traditional Chinese Medicine.

The aim of this study was to investigate the practical outcomes of traditional Chinese medicine specialty nursing clinics in the clinical setting. Outpatient services have become increasingly popular for seeking medical care. Establishing traditional Chinese medicine specialty nursing clinics can meet the medical needs of the general public, and provide patients with convenient and efficient medical services. This study employed a retrospective cross-sectional observational design to analyze the medical service status of all patients who attended the clinic since its opening. Five qualified traditional Chinese medicine nursing experts identified and implemented 5 categories of traditional Chinese medicine characteristic nursing techniques, including cupping, moxibustion, needle acupuncture, and massage. Nurses and patients evaluated the treatment outcomes for various diseases. Since the establishment of the nursing outpatient department 2 years ago, there have been over 7046 visits, with a satisfaction rate of 97.1%. Currently, 5 nursing experts are nurturing a total of 11 graduate students, conducting 5 free clinics in the nursing outpatient department, and organizing 3 visits by overseas experts. The traditional Chinese medicine specialty nursing outpatient service effectively meets the diverse medical needs of patients, alleviates the outpatient pressure on hospitals, enhances the specialized development of nurses, increases the prominence of traditional Chinese medicine specialty nursing techniques, and promotes traditional Chinese medicine culture.

International accounting network memberships and audit fees: Evidence from China.

This paper investigates the international accounting network memberships' impact on audit fees. We find that, firstly, the audit fees charged by the member audit firms are significantly higher; secondly, if the revenue, ranking or audit and accounting business share of the international network the audit firm join is higher, the charge is also higher. Additional results show that economic policy uncertainty will intensify this positive relationship, and member audit firms charge higher fees by improving their overseas expertise. We also find that international network memberships will reduce abnormal audit fees, and improve the quality of financial reports.

Priorities of Digital Development in Russian Federation Regions

Digital transformation of national economy is one of national goals, which aims at improvement of the quality and comfort of life, business development and environment competitiveness. Implementation of the Strategy of Information Society Development in the Russian Federation for 2017–2030 requires well-balanced decisions both on national and regional levels. The development of Russian regions is not homogeneous, each region has its own specificity. Thus digital transformation shall be carried out with due regard to regional specific features and processes. The article analyzes challenges and prospects of implementing digital transformations in Russian regions. As a theoretical and methodological foundation of the research works by Russian and overseas experts in the field of building information society, digital economics and digital state governance were studied. The author uses analytical materials of international expert and analytical organizations, national research institutions, materials of the Federal Service of State Statistics. The research findings can be useful for identifying cause and effect relations and key challenges that face regions in realizing strategy of digital transformation and designing priority principles of digital development on the regional level.

Telementoring for endoscopic submucosal dissection invivo training.

The provision of endoscopic training was significantly disrupted during the coronavirus disease (COVID-19) pandemic. It is difficult to provide training on endoscopic submucosal dissection (ESD) due to the complexity of the procedure and the shortage of local trainers. We have designed and conducted a simulation training course with telementoring, incorporating the concept of rapid cycle deliberate practice (RCDP). After a short tutorial on basic setup and maneuvering, the participants undergo 2 h of training on a live anesthetized pig to acquire the necessary skills for ESD. Two overseas experts were involved virtually in real time as telementors. A video camera was set up at each station, and both external and endoscopic views were transmitted live between the animal laboratory and telementors via the Zoom application. The overseas experts actively engaged in the simulation by giving live feedback and instructions to participants using visual aids supported by the meeting application. The training model utilized the concept of RCDP, where repeated immediate feedback and discussion would be carried out to enhance the efficiency of learning. Eighteen trainees were invited to participate in the course, six of them instructed by overseas telementors. Four ESD procedures were performed by participants under telementoring and achieved 100% en bloc resection without perforation. The times required for each ESD were similar with telementoring than that of on-site mentors. The establishment of telementoring has enabled knowledge and skill transfer of complex endoscopic procedures of ESD. With the limitations of international travel, this could be an alternative model allowing remote training, particularly when local experts are not readily available.

Cardiac Involvement related to COVID-19 Infection and Vaccination in Children and Adolescents – Hong Kong’s Perspective

Myocarditis and Pericarditis have many virological and immunological causes. This article described the SARS-CoV involvement to the heart in children and adolescents, also the entity Multisystem Inflammatory Syndrome in Children (MIS-C), a rare but severe consequence of SARS-CoV2 infection. Hong Kong case definition of MIS-C was listed. The consensus from overseas experts was that MIS-C should be managed by multidisciplinary team with a structured long-term follow-up to monitor the functioning of various organs and ascertain the prognosis. The side effect mRNA vaccination causing myocarditis and pericarditis is also concern of paediatricians worldwide. Hong Kong published local epidemiology of acute myocarditis and pericarditis among adolescents following Comirnaty vaccination, the local and overseas data were used in fine-tuning the COVID vaccination program in children and adolescents. To prevent severe and fatal outcome of COVID-19 diseases, it is important to educate the public and to promote COVID-19 vaccination in the community, also to continue monitoring the safety of the available vaccines.

Scientists as spies?: Assessing U.S. claims about the security threat posed by China's Thousand Talents Program for the U.S. life sciences.

In 2008, the Chinese government created the Thousand Talents Program (TTP) to recruit overseas expertise to build up China's science and technology knowledge and innovation base. Ten years later, in 2018, the Federal Bureau of Investigation (FBI) announced a new "China Initiative" that aimed to counter the transfer by U.S.-based scientists involved in the TTP of knowledge and intellectual property that could support China's military and economic might and pose threats to U.S. national security. This initiative launched a number of investigations into major U.S. federal funding agencies and universities and charged several scientists, many of them life scientists, with failing to accurately report their work and affiliations with Chinese entities and illegally transferring scientific information to China. Although the FBI cases demonstrate a clear problem with disclosure of foreign contracts and research integrity among some TTP recipients, they have failed to demonstrate any harm to U.S. national security interests. At the heart of this controversy are core questions that remain unresolved and need more attention: What is required to transfer and develop knowledge to further a country's science and technology ambitions? And can the knowledge acquired by a visiting scientist be easily used to further a country's ambitions? Drawing on literature from the field of science and technology studies, this article discusses the key issues that should be considered in evaluating this question in the Chinese context and the potential scientific, intelligence, and policy implications of knowledge transfer as it relates to the TTP.

Talent cultivation in health technology assessment: an expert survey

BackgroundHealth technology assessment (HTA) has become essential in many countries over the past few years, and the demand for HTA professionals has increased in academia, governments, and industries. This study aimed to examine which courses are most important and which training activities are most helpful for the development of HTA proficiency as perceived by HTA experts.MethodsThe survey questionnaire was developed by literature review and expert opinion. Convenience sampling was used to survey HTA experts from the industrial sector, academic/research units, and government/independent assessment organizations using an online survey tool, SurveyCake. We collected respondents’ demographic information and asked them to assess the importance of each course included in an HTA program on a 5-point Likert Scale (1 = least important; 5 = highly important). In addition, respondents were asked to assess the extent to which various activities are helpful for HTA proficiency development.ResultsA total of 158 domestic and overseas experts in HTA-related fields were invited to participate in the survey and 68 completed the questionnaire. Among the respondents, the majority were female (57.4%) and working in academia (44.1%). The mean ± standard deviation of respondents’ age and number of years spent in HTA-related fields were 43.2 ± 11.0 years and 11.3 ± 9.9 years, respectively. The course that was rated the most important was “Pharmacoeconomics/Cost-effectiveness analysis” with a score of 4.8 ± 0.4 points, followed by “Health economics” at 4.7 ± 0.7 points. Moreover, internships at HTA-related institutions were perceived to be the most helpful training activity for HTA proficiency development.ConclusionsOur study findings provide a better understanding of the requirements for developing HTA proficiency and can serve as a reference for the modification of current HTA education and training programs.

Frederick Tschopp, Landscape Architect, OE in New Zealand 1929-32

Frederick Tschopp was a naturalised American of Swiss birth who had trained as a horticulturalist specialising in landscape architecture. He and his wife arrived in Auckland in September 1929 and he soon found work with some of the local bodies there. Works and Development in Wellington later employed him in designing gardens for several important government properties. This was not a permanent position however and about July 1931 he moved to Rotorua with a major contract to beautify the city, including extensive street plantings and an upgrade of the lake shore. Most of this work was well-received but there were some dissenting voices. The contract was terminated in November 1932, but with several goodwill gestures. While in Rotorua, Frederick had visited both Hamilton and Tauranga, commenting on landscape design aspects. The family (now with the addition of a son) left New Zealand for home in Los Angeles in late November 1932. Frederick had a subsequent career with the Department of Water in California and died at Laguna Hills, Orange, California in February 1980.The reasons for Tschopp's visit to New Zealand can be interpreted in two ways. Clearly the newspapers regarded him as an overseas expert with a talent for landscape design, still a fairly new concept in the country in the late 1920s. He undoubtedly stood out as an American with drive and initiative. But he was only 24 when he first arrived, and his motives may well have been to gain overseas experience (OE) to help his chances of obtaining a lucrative job on his return to America. One paper described him as being in the course of a world tour but there is no conclusive evidence for him having spent long in other countries at this time.

China Technological Transformation: A Case Study of Telecommunications Equipment Industry

China is the world's biggest telecoms equipment exporter. Several telecommunications equipment companies from China dominate the global market, for example, Huawei and ZTE. This study aims to identify factors contributing to China's rapid technological transformation, particularly in the telecommunications equipment industry. In addition, the relationship between the government, SOE, and entrepreneurs is also identified in strengthening the sector. This study uses qualitative and quantitative approaches, data collection through literature study and observation, and data analysis using descriptive data analysis patent analysis, and network analysis. The results show that government technology policy, human resource development and education, foreign technology adoption and adaptation, together with indigenous R &amp; D efforts are essential factors in China's technological transformation process in the telecommunications equipment industry. Due to China’s government's encouragement, SOEs can innovate and encourages the growth of domestic entrepreneurship. Therefore, Indonesia can learn several things from China, including fostering innovation through various strategies such as implementing technology transfer, mentoring with overseas experts, increasing R &amp; D financing support, providing support for industry and researchers in the form of tax incentives or patent subsidies. Furthermore, strengthening collaboration and cooperation with the foreign telecommunications equipment industry with win-win schemes can offer benefits to Indonesia.

Electronic and optical properties of 3N-doped graphdiyne/MoS2 heterostructures tuned by biaxial strain and external electric field* *Project supported by the National Natural Science Foundation of China (Grant Nos. 62074053 and 61674053), the Natural Science Foundation of Henan Province, China (Grant No. 202300410237), the Program for Science & Technology Innovation Talents in Universities of Henan Province, China (Grant No. 18HASTIT030), and

The construction of van der Waals (vdW) heterostructures by stacking different two-dimensional layered materials have been recognised as an effective strategy to obtain the desired properties. The 3N-doped graphdiyne (N-GY) has been successfully synthesized in the laboratory. It could be assembled into a supercapacitor and can be used for tensile energy storage. However, the flat band and wide forbidden bands could hinder its application of N-GY layer in optoelectronic and nanoelectronic devices. In order to extend the application of N-GY layer in electronic devices, MoS2 was selected to construct an N-GY/MoS2 heterostructure due to its good electronic and optical properties. The N-GY/MoS2 heterostructure has an optical absorption range from the visible to ultraviolet with a absorption coefficient of 105 cm−1. The N-GY/MoS2 heterostructure exhibits a type-II band alignment allows the electron-hole to be located on N-GY and MoS2 respectively, which can further reduce the electron-hole complexation to increase exciton lifetime. The power conversion efficiency of N-GY/MoS2 heterostructure is up to 17.77%, indicating it is a promising candidate material for solar cells. In addition, the external electric field and biaxial strain could effectively tune the electronic structure. Our results provide a theoretical support for the design and application of N-GY/MoS2 vdW heterostructures in semiconductor sensors and photovoltaic devices.

Magnetic and electronic properties of two-dimensional metal-organic frameworks TM3(C2NH)12 * *Project supported by the National Natural Science Foundation of China (Grant Nos. 62074053, 61901161, 21906041, and 11774079), the Natural Science Foundation of Henan Province, China (Grant Nos. 202300410226, 202300410237, and 202300410100), Henan Overseas Expertise Introduction Center for Discipline Innovation (Grant No. CXJD2019005), and key scientific research projects of Colleges and

The ferromagnetism of two-dimensional (2D) materials has aroused great interest in recent years, which may play an important role in the next-generation magnetic devices. Herein, a series of 2D transition metal-organic framework materials (TM-NH MOF, TM = Sc–Zn) are designed, and their electronic and magnetic characters are systematically studied by means of first-principles calculations. Their structural stabilities are examined through binding energies and ab-initio molecular dynamics simulations. Their optimized lattice constants are correlated to the central TM atoms. These 2D TM-NH MOF nanosheets exhibit various electronic and magnetic performances owing to the effective charge transfer and interaction between TM atoms and graphene linkers. Interestingly, Ni- and Zn-NH MOFs are nonmagnetic semiconductors (SM) with band gaps of 0.41 eV and 0.61 eV, respectively. Co- and Cu-NH MOFs are bipolar magnetic semiconductors (BMS), while Fe-NH MOF monolayer is a half-semiconductor (HSM). Furthermore, the elastic strain could tune their magnetic behaviors and transformation, which ascribes to the charge redistribution of TM-3d states. This work predicts several new 2D magnetic MOF materials, which are promising for applications in spintronics and nanoelectronics.

Metronomic capecitabine as adjuvant therapy in locoregionally advanced nasopharyngeal carcinoma: a multicentre, open-label, parallel-group, randomised, controlled, phase 3 trial

Patients with locoregionally advanced nasopharyngeal carcinoma have a high risk of disease relapse, despite a high proportion of patients attaining complete clinical remission after receiving standard-of-care treatment (ie, definitive concurrent chemoradiotherapy with or without induction chemotherapy). Additional adjuvant therapies are needed to further reduce the risk of recurrence and death. However, the benefit of adjuvant chemotherapy for nasopharyngeal carcinoma remains controversial, highlighting the need for more effective adjuvant treatment options. This multicentre, open-label, parallel-group, randomised, controlled, phase 3 trial was done at 14 hospitals in China. Patients (aged 18-65 years) with histologically confirmed, high-risk locoregionally advanced nasopharyngeal carcinoma (stage III-IVA, excluding T3-4N0 and T3N1 disease), no locoregional disease or distant metastasis after definitive chemoradiotherapy, an Eastern Cooperative Oncology Group performance status of 0 or 1, sufficient haematological, renal, and hepatic function, and who had received their final radiotherapy dose 12-16 weeks before randomisation, were randomly assigned (1:1) to receive either oral metronomic capecitabine (650 mg/m2 body surface area twice daily for 1 year; metronomic capecitabine group) or observation (standard therapy group). Randomisation was done with a computer-generated sequence (block size of four), stratified by trial centre and receipt of induction chemotherapy (yes or no). The primary endpoint was failure-free survival, defined as the time from randomisation to disease recurrence (distant metastasis or locoregional recurrence) or death due to any cause, in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of capecitabine or who had commenced observation. This trial is registered with ClinicalTrials.gov, NCT02958111. Between Jan 25, 2017, and Oct 25, 2018, 675 patients were screened, of whom 406 were enrolled and randomly assigned to the metronomic capecitabine group (n=204) or to the standard therapy group (n=202). After a median follow-up of 38 months (IQR 33-42), there were 29 (14%) events of recurrence or death in the metronomic capecitabine group and 53 (26%) events of recurrence or death in the standard therapy group. Failure-free survival at 3 years was significantly higher in the metronomic capecitabine group (85·3% [95% CI 80·4-90·6]) than in the standard therapy group (75·7% [69·9-81·9]), with a stratified hazard ratio of 0·50 (95% CI 0·32-0·79; p=0·0023). Grade 3 adverse events were reported in 35 (17%) of 201 patients in the metronomic capecitabine group and in 11 (6%) of 200 patients in the standard therapy group; hand-foot syndrome was the most common adverse event related to capecitabine (18 [9%] patients had grade 3 hand-foot syndrome). One (<1%) patient in the metronomic capecitabine group had grade 4 neutropenia. No treatment-related deaths were reported in either group. The addition of metronomic adjuvant capecitabine to chemoradiotherapy significantly improved failure-free survival in patients with high-risk locoregionally advanced nasopharyngeal carcinoma, with a manageable safety profile. These results support a potential role for metronomic chemotherapy as an adjuvant therapy in the treatment of nasopharyngeal carcinoma.

Improving Diagnostic Classification of Stillbirths and Neonatal Deaths Using ICD-PM (International Classification of Diseases for Perinatal Mortality) Codes: Validation Study.

BackgroundStillbirths and neonatal deaths have long been imperfectly classified and recorded worldwide. In Hong Kong, the current code system is deficient (>90% cases with unknown causes) in providing the diagnoses of perinatal mortality cases.ObjectiveThe objective of this study was to apply the International Classification of Diseases for Perinatal Mortality (ICD-PM) system to existing perinatal death data. Further, the aim was to assess whether there was any change in the classifications of perinatal deaths compared with the existing classification system and identify any areas in which future interventions can be made.MethodsWe applied the ICD-PM (with International Statistical Classification of Diseases and Related Health Problems, 10th Revision) code system to existing perinatal death data in Kwong Wah Hospital, Hong Kong, to improve diagnostic classification. The study included stillbirths (after 24 weeks gestation) and neonatal deaths (from birth to 28 days). The retrospective data (5 years) from May 1, 2012, to April 30, 2017, were recoded by the principal investigator (HML) applying the ICD-PM, then validated by an overseas expert (EA) after she reviewed the detailed case summaries. The prospective application of ICD-PM from May 1, 2017, to April 30, 2019, was performed during the monthly multidisciplinary perinatal meetings and then also validated by EA for agreement.ResultsWe analyzed the data of 34,920 deliveries, and 119 cases were included for analysis (92 stillbirths and 27 neonatal deaths). The overall agreement with EA of our codes using the ICD-PM was 93.2% (111/119); 92% (78/85) for the 5 years of retrospective codes and 97% (33/34) for the 2 years of prospective codes (P=.44). After the application of the ICD-PM, the overall proportion of unknown causes of perinatal mortality dropped from 34.5% (41/119) to 10.1% (12/119) of cases (P<.001).ConclusionsUsing the ICD-PM would lead to a better classification of perinatal deaths, reduce the proportion of unknown diagnoses, and clearly link the maternal conditions with these perinatal deaths.

Highly efficient bifacial semitransparent perovskite solar cells based on molecular doping of CuSCN hole transport layer**Project supported by the National Key Research and Development Program of China (Grant No. 2018YFB1500103), the National Natural Science Foundation of China (Grant No. 61674084), the Overseas Expertise Introduction Project for Discipline Innovation of Higher Education of China (Grant No. B16027), and the Science and

Coper thiocyanate (CuSCN) is generally considered as a very hopeful inorganic hole transport material (HTM) in semitransparent perovskite solar cells (ST-PSCs) because of its low parasitic absorption, high inherent stability, and low cost. However, the poor electrical conductivity and low work function of CuSCN lead to the insufficient hole extraction and large open-circuit voltage loss. Here, 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ) is employed to improve conductivity of CuSCN and band alignment at the CuSCN/perovskite (PVK) interface. As a result, the average power conversion efficiency (PCE) of PSCs is boosted by ≈ 11%. In addition, benefiting from the superior transparency of p-type CuSCN HTMs, the prepared bifacial semitransparent n–i–p planar PSCs demonstrate a maximum efficiency of 14.8% and 12.5% by the illumination from the front side and back side, respectively. We believe that this developed CuSCN-based ST-PSCs will promote practical applications in building integrated photovoltaics and tandem solar cells.

Chinese standard and milestone of laparoscopic surgery for gastric cancer--Comments on the publishing of "Standard Operation Procedure of Laparoscopic surgery from CLASS-01 trial"

A multicenter, randomized, controlled clinical trial of laparoscopic gastrectomy for locally advanced distal gastric cancer (CLASS - 01 trial, ClinicalTrials.gov registration number NCT01609309) confirmed that experienced surgeons could safely performed laparoscopic D2 distal gastrectomy for patients with locally advanced gastric cancer, with minimally invasive benefits and non-inferior oncological efficacy. This provides strong evidence of the treatment of locally advanced gastric cancer via laparoscopic approach, comparable to open surgery. In September 2019, "Standard Operation Procedure of Laparoscopic D2 Distal Gastrectomy for Locally Advanced Gastric Cancer: Consensus on CLASS-01 trial" was published in the Chinese Journal of Gastrointestinal Surgery, which was highly evaluated by Chinese and overseas experts. Under the situation of wide application of minimally invasive surgery, the CLASS group published a 10-year scientific research summary and released the "Standard Operation Procedure", which has landmark significance and has become the recognized Chinese standard of laparoscopic surgery for the treatment of gastric cancer world wide. This will guide the scientific development of laparoscopic gastric cancer surgery in China, avoiding abuse or inappropriate use of minimally invasive techniques, while ensuring the rational use with fully benefits to the patients with gastric cancer.
