Analysis of assessment results of malaria elimination in Suzhou City

To analyze the assessment results of malaria elimination in Suzhou City, so as to provide references for consolidating the results of malaria elimination in the city. According to "Jiangsu Province Malaria Evaluation and Assessment Implementation Plan (2014 Edition)" and "Jiangsu City Malaria Evaluation Implementation Regulations (2015 Edition)", the assessment of the county-level cities and districts under the jurisdiction of Suzhou City was conducted. After the assessment, the municipal level assessment and evaluation were carried out, and one district was randomly selected for the assessment of malaria elimination review. The assessment score of malaria elimination in Suzhou City was 98.6 points. Wujiang District was randomly selected for review assessment, and the review score was 95.8 points. According to the 85 points attainment criteria specified by the national assessment, Suzhou City met the requirement of malaria elimination. Suzhou City has passed the inspection certification of malaria elimination in Jiangsu Province. However, the post-elimination malaria monitoring should be continued to consolidate the achievements.

Experimental study on freezing point of saline soft clay after freeze-thaw cycling

The brine leakage is a tough problem in artificial freezing engineering. This paper takes the common soft clay in Wujiang District as the study object, and calcium chloride solutions with six salinity levels were considered. The \'classic\' cooling curve method was employed to measure the freezing point of specimens after freeze-thaw. Results indicate that four characteristic stages can be observed including supercooling, abrupt transition, equilibrium and continual freezing, strongly dependent on the variation of unfrozen water content. Two characteristic points were found from the cooling curves, i.e., freezing point and initial crystallization temperature. A critical value for the former exists at which the increment lowers. The higher the saline content approximately linearly, lower the freezing point. In the initial five cycles, the freezing point increases and then stabilizes. Besides, the degree of supercooling was calculated and its correlations with water, salt and freeze-thaw cycles were noted. Finally, an empirical equation was proposed for the relationship of freezing point and three main factors, i.e., water content, saline content and freeze-thaw cycles. Comparison of calculated and measured data proves that it is reliable and may provide guidance for the design and numerical analysis in frozen soil engineering.

Emission Control in River Network System of the Taihu Basin for Water Quality Assurance of Water Environmentally Sensitive Areas

As pollution incidents frequently occurred in the functional water areas of the Taihu Basin, Yangtze Delta, effective emission control to guarantee water quality in the Taihu Basin became the priority for environmental management. In this study, a new total emission control (TEC) method was proposed with an emphasis on the concept of water environmentally sensitive areas (WESAs). This method was verified in Wujiang District and the techniques can be concluded in three steps: (1) a 1-D mathematical model for the study area was established and the model was calibrated using field measurement data; (2) based on an analysis of administrative planning and regulations, WESAs were identified as the main controlling objectives for emission control calculations. The weighting coefficient of local pollution sources was investigated to discuss the effectiveness of TEC on water quality improvement at WESAs; and (3) applying the river network mathematical model, water quality along the river segments was simulated under different pollution control plans. The results proved the effectiveness of TEC in the study area and indicated that a 14.6% reduction in the total amount of ammonia-nitrogen (NH3-N), as well as a 31.1% reduction in the total amount of chemical oxygen demand (CODcr), was essential in order to meet the water quality standard in the WESAs.

Safety and efficacy of three-dimensional shaping of titanium plate in subtemporal repair of skull defects: study protocol for a data analysis of 38 patients

Background and objectives: Repair of the damaged skull is necessary after decompressive craniectomy. Previously used autologous bone, allogeneic bone, and organic material are associated with the risk of an unsatisfactory cosmetic outcome and infection. Titanium mesh is an ideal material for cranioplasty. Digital three-dimensional shaping of titanium mesh allows it to perfectly match the skull defect and can restore the anatomic appearance of the defective area. Design: Retrospective case analysis. Methods: We analyzed the surgical and follow-up data of 38 patients with skull defects who underwent subtemporal repair using three-dimensional shaping of a titanium plate at the Department of Neurosurgery, Wujiang Hospital (The First People's Hospital of Wujiang District), Nantong University, China, from January 2015 to December 2016. Outcome measures: The primary outcome measure was the incidence of complications within 12 months after surgery. The secondary outcome measures were the Glasgow outcome scale score, Karnofsky performance scale score, National Institutes of Health stroke scale score, and skull computed tomography scan results at 1, 6, 12, 18, and 24 months after repair. Partial results have been obtained for 38 patients who have been followed up for 6 to 24 months. No complications or adverse reactions occurred. Skull computed tomography scan results revealed that the titanium mesh and nail were well fixed, the skull shape was symmetrical, and no subcutaneous effusion or intracranial hemorrhage occurred. Discussion: Complications, neurological function, and imaging findings in patients with frontotemporal skull defects provide an experimental basis for three-dimensional shaping of titanium plates in subtemporal repair of frontotemporal defects. Ethics and dissemination: The study design was completed in May 2017. The protocols had been approved by the Ethics Committee of The First People's Hospital of Wujiang District in June 2017. This trial was registered in October 2017. Data of patients, who were treated from January 2015 to December 2016, were analyzed in June 2017. Data analysis will be finished in December 2017. The results of the trial will be published in a peer-reviewed journal and will be disseminated via various forms of media. Trial registration: This trial has been registered in the Chinese Clinical Trial Registry (identifier: ChiCTR-IOC-17012947). All data collection and analysis are currently ongoing.
