Evaluation Of Clinical Effects Research Articles

Visual analysis on the study status and trends of acupuncture and moxibustion for Alzheimer's disease.

The research history, hot spots and frontier trends of acupuncture and moxibustion for Alzheimer's disease (AD) were explored using knowledge graph technology. The articles on acupuncture and moxibustion for AD were searched from 6 databases, i.e. CNKI, VIP, Wanfang, SinoMed, Pubmed and Web of Science, from January 1st, 1993 to January 1st, 2023. Using CiteSpace6.2.R2 Advance and VOSviewer V1.6.19 softwares, the knowledge map was graphed and the visual analysis was performed. A total of 1 228 Chinese and 309 English articles were included. The high-frequency keywords were generally divided into the keywords of clinical diseases (AD, dementia), those of therapeutic methods (electroacupuncture, acupuncture-moxibustion and acupuncture) and those of mechanism study (β-amyloid, mice). Thirteen keyword clusters were formed among the articles of Chinese version, e.g. acupuncture-moxibustion, dementia, acupuncture and electroacupuncture; and 8 clusters were obtained among English articles, e.g. electroacupuncture, drug therapy and hippocampus. The high-frequency keywords of acupoints included Baihui (GV 20), Dazhui (GV 14), Yintang (GV 24+), Zusanli (ST 36), Fenglong (ST 40), etc. Six clusters of "acupuncture techniques → acupoints" were obtained for the treatment of AD with acupuncture and moxibustion. The therapeutic methods and modes of AD with acupuncture and moxibustion are constantly progressed, the development of clinical research tends to the evaluation of novel therapeutic mode and clinical effect, and the mechanism of acupuncture and moxibustion for the effect on AD are more deeply explored. Among the various therapeutic methods, acupuncture-moxibustion, acupuncture and electroacupuncture have been early predominant; while, many novel methods are gradually displayed later, such as music electroacupuncture and hydro-acupuncture. In recent 30 years, among Chinese and English articles for the studies of AD treated with acupuncture and moxibustion, the theme of them focuses on the two aspects, the observation of clinical effect and the mechanism research. It is found that the clinical therapeutic methods have been gradually improved and the mechanism exploration been deepened.

Clinical Evaluation of Curative Effect of SRM-IV Treatment System for Treating Refractory Benign Paroxysmal Positional Vertigo.

Objective: This study aimed to explore the clinical characteristics of the automatic vestibular function therapy system (SRM-IV) fully automated benign paroxysmal positional vertigo (BPPV) diagnosis and treatment system in the treatment of refractory BPPV and evaluate the clinical effect of reduction therapy. Methods: The clinical data of 39 patients with refractory BPPV who were admitted to our hospital's department of neurology from January 2020 to May 2022 were analyzed retrospectively. Results: Eighteen, 14, and 5 patients were cured after 3, 4, and 5 reduction treatments, respectively, with the SRM-IV vertigo diagnosis and treatment system. Another 2 patients were unable to recover through canalith repositioning procedure, although they improved after alternating between manual repositioning and Brandt-Daroff habituation training. Conclusions: Most patients with refractory BPPV were cured after canalith repositioning procedure. The causes of intractability might involve many different aspects. Longer disease history and poor otolith mobility are also one of the reasons for this difficulty.

Long-term Outcome of Isobar TTL System for the Treatment of Lumbar Degenerative Disc Diseases.

The Isobar TTL dynamic fixation system has demonstrated favorable outcomes in the short-term treatment of lumbar degenerative disc diseases (LDDs). However, there is a paucity of extensive research on the long-term effects of this system on LDDs. This study aimed to evaluate the long-term clinical and radiological outcomes of patients with LDDs who underwent treatment utilizing the Isobar TTL dynamic fixation system. The study analyzed the outcomes of 40 patients with LDDs who underwent posterior lumbar decompression and received single-segment Isobar TTL dynamic internal fixation at our hospital between June 2010 and December 2016. The evaluation of clinical therapeutic effect involved assessing postoperative pain levels using the visual analogue scale (VAS) and Oswestry disability index (ODI), both before surgery, 3 months after, and the final follow-up. To determine the preservation of functional motion in dynamically stable segments, we measured the range of motion (ROM) and disc height of stabilized and adjacent segments preoperatively and during the final follow-up. Additionally, we investigated the occurrence of adjacent segment degeneration (ASD). Forty patients were evaluated, with an average age of 44.65 years and an average follow-up period of 79.37 months. Fourteen patients belonged to the spondylolisthesis group, while the remaining 26 were categorized under the stenosis or herniated disc group. The preoperative ROM of the stabilized segment exhibited a significant reduction from 8.15° ± 2.77° to 5.00° ± 1.82° at the final follow-up (p < 0.001). In contrast, there was a slight elevation in the ROM of the adjacent segment during the final follow-up, increasing from 7.68° ± 2.25° before surgery to 9.36° ± 1.98° (p < 0.001). The intervertebral space height (IH) in the stabilized segment exhibited a significant increase from 10.56 ± 1.99 mm before surgery to 11.39 ± 1.90 mm at the one-week postoperative follow-up (p < 0.001). Conversely, there was a notable decrease in the IH of the adjacent segment from 11.09 ± 1.82 mm preoperatively to 10.86 ± 1.79 mm at the one-week follow-up after surgery (p < 0.001). The incidence of ASD was 15% (6/40) after an average follow-up period of 79.37 months, with a rate of 15.38% (4/26) in the stenosis or herniated disc group and 14.29% (2/14) in the spondylolisthesis group; however, no statistically significant difference was observed in the occurrence of ASD among these groups (p > 0.05). The Isobar TTL dynamic fixation system is an effective treatment for LDDs, improving pain relief, quality of life (QoL) and maintaining stabilized segmental motion. It has demonstrated excellent long-term clinical and radiographic results.

Subconjunctival liposomal sirolimus vs. cyclosporine or tacrolimus as treatment of keratoconjunctivitis sicca in dogs: A double-blind, randomized study.

To compare the safety and efficacy of a 100 microgram subconjunctival injection of liposome-encapsulated sirolimus (SCJS) to cyclosporine (CsA) or tacrolimus (CsA/T) for the treatment of keratoconjunctivitis sicca (KCS) in dogs. Dogs with signs and symptoms of KCS were block-randomized to one of two treatment groups: Biweekly SCJS or conventional treatment (CsA/T). Schirmer tear test 1 (STT-1) scores, conjunctival hyperemia (CH) scores, corneal opacity (CO) scores, and clinical evaluation of potential side effects were recorded every 2 weeks for 14 weeks for both groups. Differences between groups were analyzed using the mixed results ANOVA and U-Mann Whitney tests (p < .05 was considered significant). A total of 30 eyes were included in the study, of which 20 eyes completed follow-up. There was no statistically significant interaction between the treatment group and time on STT-1 score (p = .165), and median CH and CO scores showed no statistically significant differences between groups (p = .353 and p = .393, respectively). There were no clinically significant side effects present in any subject at any time. In this trial, a 1 mg/mL (100 micrograms) SCJS every 2 weeks showed similar safety and efficacy profiles as daily CsA/T in dogs with KS after 14 weeks of treatment. Larger studies should be performed to further assess SCJS as an alternative treatment for KCS.

Safety, Tolerability, and Pharmacodynamics of the ADAMTS-5 Nanobody M6495: Two Phase 1, Single-Center, Double-Blind, Randomized, Placebo-Controlled Studies in Healthy Subjects and Patients With Osteoarthritis.

To assess the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of single and multiple injections of M6495, a disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS-5) nanobody, in healthy volunteers and patients with osteoarthritis. Two randomized, placebo-controlled, double-blind studies were performed. Study 1 enrolled 54 healthy male volunteers who received one subcutaneous (s.c.) injection of M6495 (1-300 mg) or placebo (ratio 2:1), evaluating safety, PK, and PD as changes in the serum aggrecan fragment alanine-arginine-glycine-serine (ARGS). Study 2 enrolled 32 patients with osteoarthritis with Kellgren-Lawrence grades 2 to 4 and pain greater than or equal to 40 on the Western Ontario and McMaster Universities Arthritis Index pain subscale at screening and evaluated the safety, PK, and PD of three doses every two weeks (75-300 mg per dose) or six once-weekly M6495 s.c. doses (300 mg) or placebo (ratio 3:1) over 106 days' follow-up. M6495 in single and multiple doses of less than or equal to 300 mg s.c. weekly was well tolerated with no clinically significant changes in any safety parameter. Adverse events more frequently reported in the M6495 groups were mostly mild cases of injection site reactions, myalgia, and nausea, which resolved after treatment cessation. The elimination half-life of single s.c. doses of M6495 ranged from 79 to 267 hours. M6495 administration substantially reduced serum ARGS levels, indicative of target engagement and indicating disease-modifying potential of M6495. Treatment with M6495 in single and multiple doses up to and including 300 mg s.c. was found to be well tolerated and adequately safe for further clinical evaluation of potential disease-modifying effects.

Multilevel Pedicle Subtraction Osteotomy for Correction of Thoracolumbar Kyphosis in Ankylosing Spondylitis: Clinical Effect and Biomechanical Evaluation.

To compare the clinical outcomes and biomechanical characteristics of 1-, 2-, and 3-level pedicle subtraction osteotomy (PSO), and establish selection criteria based on preoperative radiographic parameters. Patients undergone PSO to treat ankylosing spondylitis from February 2009 to May 2019 in Sun Yat-sen Memorial Hospital of Sun Yat-sen University were enrolled. According to the quantity of osteotomy performed, the participants were divided into group A (1-level PSO, n = 24), group B (2-level PSO, n = 19), and group C (3-level PSO, n = 11). Clinical outcomes were assessed before surgery and at the final follow-up. Comparisons of the radiographic parameters and quality-of-life indicators were performed among and within these groups, and the selection criteria were established by regression. Finite element analysis was conducted to compare the biomechanical characteristics of the spine treated with different quantity of osteotomies under different working conditions. Three-level PSO improved the sagittal parameters more significantly, but resulted in longer operative time and greater blood loss (p < 0.05). Greater stress was found in the proximal screws and proximal junction area of the vertebra in the model simulating 1-level PSO. Larger stress of screws and vertebra was observed at the distal end in the model simulating 3-level PSO. Multilevel PSO works better for larger deformity correction than single-level PSO by allowing greater sagittal parameter correction and obtaining a better distribution of stress in the hardware construct, although with longer operation time and greater blood loss. Three-level osteotomy is recommended for the patients with preoperative of global kyphosis > 85.95°, T1 pelvic angle > 62.3°, sagittal vertical alignment > 299.55 mm, and pelvic tilt+ chin-brow vertical angle > 109.6°.

Evaluation of Short-Term Clinical Effects of a Novel Repetitive Facilitation Exercise Training Program Using a Hemiplegic Elbow Extension Rehabilitation System

Repetitive Facilitation Exercise (RFE) is known as an effective rehabilitation method that can elicit brain plasticity. In our previous study, we developed a hemiplegic upper limb rehabilitation system that can train the elbow and shoulder based on RFE theory. The system consists of a selective Arm-DoF constrainable mechanism and a multiple facilitative stimulus timing and duration control system. The selective Arm-DoF constrainable mechanism has three DoF, making it possible to selectively restrict a DoF of the shoulder or elbow. The multiple facilitative stimulation timing and duration control system only has an electrical stimulation source and a vibrator and no large actuators to perform the training exercise. In this study, we undertook an evaluation of the short-term clinical effects of a proposed elbow training program using the hemiplegic upper limb rehabilitation system. The training method consists of two sets, each involving 50 repetitions of the elbow extension exercise programmed in our system. We evaluated the short-term training effects through clinical trials for five stroke patients using the above method. In the evaluation, 10 repetitions of pre/post-tests without any facilitative stimulus were performed before and after the two sets of training. As a result, the maximum angular velocities or the average angular velocities of the elbow extensions improved significantly in most subjects. These results indicate that the quickness or the smoothness of elbow extension movements in the hemiplegic limb improved. Therefore, our clinical experiments support the short-term clinical benefits of the proposed method as well as the practicality of quantitative evaluation using our system.

Central and Peripheral Motor Conduction Studies by Single-Pulse Magnetic Stimulation.

Single-pulse magnetic stimulation is the simplest type of transcranial magnetic stimulation (TMS). Muscle action potentials induced by applying TMS over the primary motor cortex are recorded with surface electromyography electrodes, and they are called motor-evoked potentials (MEPs). The amplitude and latency of MEPs are used for various analyses in clinical practice and research. The most commonly used parameter is the central motor conduction time (CMCT), which is measured using motor cortical and spinal nerve stimulation. In addition, stimulation at the foramen magnum or the conus medullaris can be combined with conventional CMCT measurements to evaluate various conduction parameters in the corticospinal tract more precisely, including the cortical-brainstem conduction time, brainstem-root conduction time, cortical-conus motor conduction time, and cauda equina conduction time. The cortical silent period is also a useful parameter for evaluating cortical excitability. Single-pulse magnetic stimulation is further used to analyze not only the central nervous system but also the peripheral nervous system, such as for detecting lesions in the proximal parts of peripheral nerves. In this review article we introduce four types of single-pulse magnetic stimulation-of the motor cortex, spinal nerve, foramen magnum, and conus medullaris-that are useful for the diagnosis, elucidation of pathophysiology, and evaluation of clinical conditions and therapeutic effects. Single-pulse magnetic stimulation is a clinically useful technique that all neurologists should learn.

Abstract 17038: Mineralocorticoid Antagonist Use for Transthyretin Amyloid Cardiomyopathy and Associated Outcomes

Background: Diuretics have been the mainstay of symptomatic treatment for patients with amyloid cardiomyopathy however, there remains no established guideline directed medical therapy for this population. The anti-fibrotic properties of mineralocorticoid antagonists (MRA) are intriguing for potential use in transthyretin amyloid cardiomyopathy (ATTR CM); while they have shown promise for treatment of patients with heart failure with preserved ejection fraction, their use has never been studied specifically in the ATTR CM population. The purpose of our study is to evaluate the real-world use of MRA and associated outcomes in patients with ATTR CM at a large cardiac amyloid treatment center. Methods: Between 2009 and 2023, 168 patients with ATTR CM at our center were assessed for history of MRA use. Biomarkers, including baseline levels of troponin and natriuretic peptides, as well as kidney function were assessed. We also assessed the outcomes of 5-year survival, need for heart transplant, hospitalization, and mechanical circulatory support (MCS) use. Results: Of the 168 patients, 49 (29%) had a history of MRA use and 119 (71%) had no prior use. Between the two groups, there was no significant difference in age, frequency of ATTR CM subtype, kidney disease, or biomarker level at the time of diagnosis. While 5-year survival and need for MCS were similar between the two groups, there was a higher rate of transplant and hospitalization in the MRA use group. Conclusion: In a cohort of patients with ATTR CM, MRA use is uncommon and was not associated with improved outcomes. It was associated with higher rates of hospitalizations and heart transplantation; however, this may represent confounding by indication. Future investigations with larger registry cohorts and randomized control trials are warranted for further evaluation of biological and clinical effect of MRA use.

Clinical evaluation of resin infiltration treatment masking effect on hypomineralised enamel surfaces

BackgroundResin infiltration is a micro-invasive treatment for molar incisor hypomineralisation (MIH). In this study it was aimed to evaluate the masking effect of resin infiltration treatment (ICON) on hypomineralised enamel surface of permanent anterior teeth by using laser fluorescence, spectrophotometer, and cross-polarisation photography.MethodsA total of 116 permanent central incisors in 37 patients were included in the study. The resin infiltration treatment (Icon®) was applied to the teeth with MIH; the healthy teeth received no treatment (control). Hypomineralised enamel lesions were evaluated by ICDAS II criteria. DIAGNOdent Pen was used to assess the lesions and healthy enamel surface quantitatively. Colour changes in enamel lesions were evaluated by using a spectrophotometer (VITA EasyShare). Each enamel lesion was imaged using a cross-polarization technique before and after treatment. All photos were assessed using Image J to evaluate the changes in lesion size. Enamel lesions were evaluated before; immediately after; 1; 3; and 6 months after treatment. Statistical significance was set as p < 0.05.ResultsAfter the resin infiltration, significant decreases were found in the mean DIAGNOdent values for the treatment group (p < 0.05). The colour differences before and after treatment significantly differed in all follow-ups (p < 0.05). In the treatment group, lesion areas decreased significantly after treatment (p < 0.05).ConclusionsThe resin infiltration treatment has a masking effect on MIH lesions without cavities, with stable outcomes after six months. The cross-polarization photography technique may be use to evaluate the lesion size instead of photography with flash.Trial registration.NCT04685889 (registered 28 December 2020).

Evaluation of clinical effects of a multidisciplinary-collaborated cancer support team for gastrointestinal cancer chemotherapy: prospective observational study protocol of M-CAST study

BackgroundAlthough the multidisciplinary-collaborated team approach in cancer treatment has recently become popular, prospectively evaluated evidence is limited. We started a multidisciplinary-collaborated cancer support team (MCST) to facilitate cooperation across multidisciplinary medical staff in our hospital and established clinical evidence of supportive care. This study aimed to prospectively evaluate the clinical activity and effect of MCST in patients with gastrointestinal cancer receiving chemotherapy.MethodsThis is a single-center, single-arm, observational study. Patients with gastrointestinal cancer scheduled to receive chemotherapy are enrolled and supported by the MCST. The primary endpoints are the number of interventions by medical staff and the number of patients who showed improvement in side effects. The secondary endpoints are the severity of side effects, medical expenses, number of consultations, the acceptance rate of prescription recommendations, adjuvant chemotherapy completion rates, dose intensity, and time required for co-medical intervention. In addition, medical staff and attending physicians evaluate all adverse events.DiscussionThis study is expected to contribute to establishing new cancer-supportive care teams for patients with gastrointestinal cancer receiving chemotherapy and those with cancer receiving chemotherapy.Trial registrationThis trial was registered in the Japan Registry of Clinical Trials (jRCT) as jRCT1030220495.The date of first registration, 29/11/2022, https://jrct.niph.go.jp/search

The clinical effect evaluation of multidisciplinary collaborative team combined with palliative care model in patients with terminal cancer: a randomised controlled study

ObjectiveTo evaluate the clinical effect of a multidisciplinary collaboration team combined with a palliative care model in patients with terminal cancer.MethodA total of 84 patients diagnosed with terminal cancer in our hospital were included and randomly divided into an intervention group and a control group, with 42 cases in each group. Patients in the intervention group were treated by a multidisciplinary collaborative team combined with the palliative care model, and patients in the control group were treated by routine nursing intervention. The Self-rating Anxiety Scale (SAS) and the Self-rating Depression Scale (SDS) were used to evaluate negative emotions and anxiety and depression of patients before and after intervention. The Quality of Life Scale (European Organization for Research and Treatment of Cancer [EORTC] QLQ-C30) and Social Support Scale (SSRS) were used to evaluate the quality of life and social support of patients. This study has been registered in 13/01/2023 (ClinicalTrials.gov Identifier: NCT05683236).ResultThe general data of the two groups were comparable. After intervention, the SAS (43.7 ± 7.4 vs. 54.2 ± 9.3) and SDS scores (38.4 ± 6.5 vs. 53.1 ± 8.4) of the intervention group were significantly lower than those of the control group. The total SSRS score, subjective support score, objective support score and utilisation of support of the intervention group were significantly higher than those of the control group (P < 0.05). The overall quality of life score of the intervention group was higher than that of the control group, and the difference was statistically significant (79.5 ± 4.5 vs. 73.2 ± 3.6, P < 0.05). The scores of each functional scale were significantly higher than those of the control group (P < 0.05).ConclusionCompared with conventional nursing, the application of the multidisciplinary collaborative team combined with tranquilisation therapy in patients with terminal cancer can significantly reduce the anxiety and depression of patients, enable patients to obtain comprehensive social support, and effectively improve the quality of life of patients.Trial registrationClinicalTrials.gov Identifier NCT05683236, 13/01/2023, Retrospectively registered.

Evaluation of the relationship between left atrial strain and exercise tolerance in patients with hypertrophic cardiomyopathy by treadmill stress echocardiography.

The aim of this study is to evaluate the left atrial strain (LAS) in patients with hypertrophic cardiomyopathy (HCM) by treadmill exercise stress echocardiography, combined with three-dimensional speckle tracking technology, for predicting exercise tolerance. A total of 97 patients with HCM who underwent treadmill exercise stress echocardiography were recruited in Sichuan Provincial People's Hospital between January 2018 and January 2021, and 30 control subjects were selected to be included in the normal group. HCM patients with their metabolic equivalents (METS) ≤ 6.0 were included in the HCM-1 group, while those with METS > 6.0 were included in the HCM-2 group. The LAS and exercise tolerance were analyzed. The ultrasound parameters that could predict a decrease in exercise tolerance were screened, and a predictive model was constructed. It was found that METS, Rest-LASr, Rest-LAScd, and Rest-LASct were significantly lower in HCM patients than those in normal controls. There was a significant difference in age, Target_HR, LVMI, LAVI, E/e'-Rest, E/e'-Peak, Rest-LASr, Rest-LAScd, and Rest-LASct between the HCM-1 and the HCM-2 groups. LASr is an independent resting echocardiographic predictor of METS ≤ 6.0. LASr remained significant for predicting different subtypes (AHCM, asymmetric HCM, and obstructive HCM). Rest-LASr (AUC 0.990) was better at predicting METS ≤ 6.0 than Peak-E/e' (AUC 0.753). A multivariate model (LASr + Age + Target_HR) was established for METS prediction. Left atrial reservoir strain (LASr) has the strongest association with METS ≤ 6.0. The LASr is an independent resting predictor of METS ≤ 6.0 and has a good performance record in predicting different subtypes of HCM. Compared with the traditional parameters, Peak-E/e' and Rest-E/e', Rest-LASr is the best predictor. Rest-LASr can serve as a reliable method for HCM patients who are unable to undergo exercise testing but require an urgent evaluation of their METS, which provides a basis for clinical treatment decision-making and treatment effect evaluation.

Clinical Effect Evaluation of Concentrated Growth Factor in Endodontic Microsurgery: A Cross-Sectional Study

IntroductionConcentrated growth factor (CGF) is the third-generation platelet concentrate product. This study aimed to evaluate whether the use of CGF during endodontic microsurgery had a positive influence on surgical outcomes. MethodsFifty-four patients who underwent endodontic microsurgery from January 2017 to November 2021 were enrolled. They were assigned to the CGF and the control groups according to whether CGF was used during the surgery and followed up at 6, 12, and 18 months after surgery. Preoperative classification of the cases and follow-up radiographic outcomes were based on Kim’s classification and Molven’s criteria, respectively, and evaluated by 2 calibrated endodontists. The Student t test and χ2 test were used to assess the baseline of 2 groups. Rank sum test was used to determine whether CGF had an impact on the surgical outcome. ResultsThirty-one patients (41 periapical lesion sites) were included in the CGF group, and 23 patients (26 periapical lesion sites) were included in the control group. The overall success rate of endodontic microsurgery was greater than 90%. The baseline of the 2 groups had no difference (P < .05). In the CGF group, the success rate was always 100% in 3 follow-ups, whereas the success rate was 84.2%, 92.8%, and 90%, respectively, in the control group. The success rate between the CGF group and the control group was statistically significant in all 3 follow-up points (P < .05). ConclusionsThe application of CGF during endodontic microsurgery might have a positive influence on surgical outcomes, thus, its prognosis. However, higher-grade evidence is needed to demonstrate its role.

Ketogenic diet in children and adolescents: The effects on growth and nutritional status

The ketogenic diet is known to be a possible adjuvant treatment in several medical conditions, such as in patients with severe or drug-resistant forms of epilepsy. Its use has recently been increasing among adolescents and young adults due to its supposed weight-loss effect, mediated by lipolysis and lowered insulin levels. However, there are still no precise indications on the possible use of ketogenic diets in pediatric age for weight loss. This approach has also recently been proposed for other types of disorder such as inherited metabolic disorders, Prader-Willi syndrome, and some specific types of cancers. Due to its unbalanced ratio of lipids, carbohydrates and proteins, a clinical evaluation of possible side effects with a strict evaluation of growth and nutritional status is essential in all patients following a long-term restrictive diet such as the ketogenic one. The prophylactic use of micronutrients supplementation should be considered before starting any ketogenic diet. Lastly, while there is sufficient literature on possible short-term side effects of ketogenic diets, their possible long-term impact on growth and nutritional status is not yet fully understood, especially when started in pediatric age.

Evaluating the tumor stratification with a lysosomal pH sensitive-probe by fluorescence lifetime imaging

Owing to the anaerobic metabolism in the tumor, abundant acidic metabolites are produced and accumulated in the cells. Therefore, the cells in different tumor layers are directly linked to the pH micro-environment. Nevertheless, due to the lack of robust tools, the high-efficient evaluation of the acidic micro-environment of tumor stratification faces the challenge of accurate diagnosis. We designed a new pH sensitive fluorescent lifetime probe target to lysosomes. As we expected, the fluorescence lifetime of PLN possesses a good linear fit to the pH value, which could detect the pH change at a single lysosome level in real time, and then evaluate the different acidity of tumor stratification. The probe PLN is successfully used to evaluate the tumor stratification by fluorescence lifetime imaging microscopy (FLIM) for the first time, which is of great significance in the preoperative diagnosis of clinical tumor treatment or evaluation of drug delivery effect.
