Objective To explore the effect of 12-week simplified Tai Chi training on rehabilitation and neuromuscular control in individuals with chronic ankle instability(CAI).Methods Thirty-four partic-ipants with CAI were randomly divided into an experimental group and a control group,each of 17.The control group received 12-week health education,while the experimental group underwent simpli-fied Tai Chi training for the same length.Before and after the intervention,both groups were evaluat-ed their self-reported instability feeling,ankle muscle strength,proprioception and dynamic postural stability.Results After intervention,a significant increase was observed in the average Cumberland An-kle Instability Tool(CAIT),the maximum extension distance in the posteromedial and posterolateral di-rections of the modified Star Excursion Balance Test(mSEBT)in,as well as the ankle peak torque in plantarflexion,inversion and eversion(P<0.05)in the experimental.Moreover,the ankle passive motion proprioceptive threshold in plantarflexion and inversion decreased significantly in the experimental group after intervention(P<0.05).Meanwhile,after intervention,the average CAIT score,maximum ex-tension distances in the posteromedial and posterolateral directions in the mSEBT,and the ankle peak torques in plantarflexion,inversion and eversion of the experimental group were significantly higher than the control group(P<0.05),while the ankle passive motion proprioceptive threshold in plantarflex-ion was significantly lower than the latter(P<0.05).Conclusion Twelve-week simplified Tai Chi train-ing can improve the clinical subjective instability of CAI participants,maybe related to the improve-ment of ankle muscle strength,proprioception and dynamic postural stability.Therefore,it is suggest-ed that simplified Tai Chi should be one of the rehabilitation methods for CAI patients.

Objective To investigate the role and mechanism of suramin(Sur)in acetaminophen(APAP)-induced acute liver injury in mice.Methods 8-10 weeks old C57BL/6J mice were randomly divided into the APAP group and APAP+Sur group(20 mg/kg suramin was injected 1 h before).After 18 hrs of fasting,400 mg/kg APAP was injected intraperitoneally to establish a mouse model of acute liver failure and the survival rate was recorded.An acute liver injury model of mice was established via intraperitoneal injection of 300 mg/kg APAP(other conditions remained unchanged).A control group was also established,with liver tissues and serum collected at 0,2,and 12 hours post-APAP treatment.ELISA and CBA techniques were adopted to detect the release of alanine aminotransferase(ALT)and aspartate aminotransferase(AST)in serum and the secretion of inflammatory factors.H&E staining and immunohistochemistry were used to detect liver tissue necrosis and inflammatory cell infiltration.DCFA-DH and ELISA techniques were used to detect the levels of reactive oxygen species(ROS),malondialdehyde(MDA)and glutathione(GSH)in liver tissues.Western blotting was employed to assess the activation of the JNK signaling pathway in liver tissues.Results Suramin treatment improved the survival rate of APAP-induced mice,reduced the release of transaminases and inflammatory factors in serum,and alleviated APAP-induced liver cell necrosis and inflammatory cell infiltration in the liver.Suramin treatment delayed APAP-induced GSH depletion in the liver,reduced MDA and ROS levels,and inhibited JNK pathway activation.Conclusion This study has confirmed the protective effect of suramin against acetaminophen-induced acute liver injury in mice.The mechanism is potentially related to oxidative stress and inflammation.

Objective·To analyze the epidemiological characteristics of risk factors for cardiovascular diseases and malignant tumors based on the Shanghai community elderly cohort.Methods·The study subjects were selected from the Shanghai community elderly cohort established from February to August 2019,with a total of 17 948 people.The study subjects were divided into 4 groups according to self-reported presence or absence of tumors and/or cardiovascular diseases during the baseline survey:tumor-free and non-cardiovascular disease group,single cardiovascular disease group,single tumor group and tumor cardiovascular disease co-occurrence group.The differences among the four groups of subjects were collected and compared in terms of demographic characteristics and physiological indicators,daily living habits(smoking,drinking tea,drinking coffee,drinking carbonated drink,drinking alcohol,sedentary time,physical activity level and sleep quality),past medical history,psychological status(depression and anxiety)and dietary compliance.Results·Among the study subjects,60.1%of tumor patients were complicated with cardiovascular diseases.The differences among the four groups of subjects in age,gender,educational level,pre-retirement occupation,waist circumference,hip circumference and body mass index were statistically significant(all P<0.05).Compared with the tumor-free and non-cardiovascular disease group,the single cardiovascular disease group,single tumor group and tumor cardiovascular disease co-occurrence group all exhibited lower proportions of smoking and high physical activity levels(all P<0.05),and higher proportion of sedentary time exceeding 4 h/d and poor sleep quality(all P<0.05);the proportion of subjects with past medical histories including hyperlipidemia,peripheral vascular disease,endocrine system disease,respiratory system disease,urinary system disease and digestive system disease of the single cardiovascular disease group and the tumor cardiovascular disease co-occurrence group was higher(all P<0.05),and the proportion of subjects with depression and anxiety was also higher(all P<0.05).Furthermore,compared with the tumor-free and non-cardiovascular disease group,the single cardiovascular disease group had lower compliance rates of poultry,fish,fruit and liquid milk(all P<0.05).Among the four groups,only the compliance rate of vegetable intake exceeded 50%,while the compliance rates of poultry,fish,fruit,liquid milk and tubers were all below 20%.Conclusion·In the elderly population of Shanghai communities,over half of malignant tumor patients are concomitant with cardiovascular diseases.Unhealthy daily habits are prevalent among those with cardiovascular diseases,tumors and tumor-cardiovascular disease co-occurrence.The intake of many foods in the elderly of the community do not reach the levels recommended by Chinese Dietary Guidelines.

Objective To explore and validate the mechanism of Prepared Radix Polygoni Multiflori in the treatment of NAFLD based on network pharmacology and animal non-alcoholic fatty liver disease(NAFLD)model experiments.Methods Consult the literature to compare the differences between Radix Polygoni Multiflori and Prepared Radix Polygoni Multiflori(PRPM).Herb database and SwissADME database were used to screen the active ingredients of Prepared Radix Polygoni Multiflori,SwissTargetPrediction database was used to predict its targets,OMIM,DISGENET and GEENCARDS databases were used to screen the NAFLD-related targets,conduct GO functional enrichment analysis and KEGG pathway enrichment analysis.The active ingredient-target-KEGG signaling pathway-NAFLD network was mapped later.The mice with NAFLD were treated with Prepared Radix Polygoni Multiflori by gavage for 8 weeks;serum triglyceride level and alanine aminotransferase(ALT)activity were measured;the liver lesions were observed by HE staining;the potential mechanism of action of Radix Polygoni Multiflori in the treatment of NAFLD was verified by Western blot.Results The differences between Radix Polygoni Multiflori and PRPM were consulted.Six pharmacological components and 32 potential action targets of Radix Polygoni Multiflori for the treatment of NAFLD were screened by network pharmacology,GO and KEGG pathways were enriched to lipid and atherosclerosis-related pathways,AMPK signaling pathway,etc.;HE staining verified that Prepared Radix Polygoni Multiflori has the function of improving NAFLD and is associated with the alteration of FASN,ACC,SCD protein of AMPK signaling pathway.Conclusion Radix Polygoni Multiflori has the potential to improve NAFLD by regulating FASN,ACC and SCD.

With the improvement of people's living standard and the strengthening of people's recognition of dental caries prevention and treatment, enamel remineralization has attracted extensive attention. Fluoride, bioactive glass and casein phosphopeptide-amorphic calcium phosphate (CPP-ACP) are the most widely studied remineralisation agents at present, which have a certain effect of promoting enamel remineralization. The results of different studies shown that the effect of CPP-ACP combined with fluoride was quite different, which may be affected by many factors. In this paper, the recent progress of the combined application of CPP-ACP and fluoride on enamel remineralization was reviewed, and various influencing factors were analyzed in order to provide references for future experimental design and clinical applications.

OBJECTIVE: To explore the clinical characteristics, genetic basis and clinical treatment of seven neonates with congenital nephrogenic diabetes insipidus (NDI). METHODS: Clinical data of the patients were collected. High-throughput sequencing was carried out to detect potential variants. Sanger sequencing was used to verify the results. RESULTS: The patients were all males, with the age of onset being 10 to 21 days. All patients were admitted to the hospital for intermittent fever as the first symptom during the neonatal period. Additional symptoms had included polydipsia and polyuria. After the treatment, 5 patients had recovered, the remainders still had NDI symptoms and developmental retardation. Five children were found to harbor pathogenic variants of the AVPR2/AQP2 gene, which included one in-frame mutation of c.645_646insGCACCTACCCTGGGTATCGCC, two missense mutations of c.541C>T and c.419C>A, and two hemizygous deletions of the AVPR2/AQP2 gene. Among these, two were unreported previously. Cases 6 and 7 were a pair of twins. Both had carried homozygous missense variants of c.538G>A of the AVPR2/AQP2 gene, which was known to be pathogenic. CONCLUSION AVPR2/AQP2 is the main pathogenic gene for congenital NDI, for which two novel pathogenic variants have been discovered in this study. Above results have provided a basis for clinical diagnosis and genetic counseling for the affected pedigrees.

Objective: To summarize and critically assess the evidence from randomized controlled trials (RCTs) of acupuncture in treating dry eye syndrome (DES) according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and the Cochrane Collaboration recommendations. Methods: A search of PubMed, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and Embase was made from their inception to August 2016, as well as Chinese, Japanese, and Korean databases. Two reviewers independently selected RCTs and assessed the methodological quality. Meta-analysis and the level of evidence were processed by RevMan 5.3 and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Results: After selection, 8 trials were subjected to our systematic review. The methodological quality was low generally. The 3-10 weeks follow-up showed that acupuncture improved the tear film break-up time (BUT) (MD=1.33, 95%CI=1.01-1.66, 619 participants). The mean difference of Schirmer's test was 1.73 mm (95%CI=1.28-2.18, 618 participants) between the acupuncture group and the control group. The subjective variables exhibited no significant differences. Conclusion: The low methodological quality of the trials does not suggest drawing firm conclusions on the value of acupuncture therapy for DES. Acupuncture treatment may have some effects on the tear film BUT and Schirmer's test, but not on the subjective symptoms. Well-planned large-scale high-quality RCTs are needed to make it clear whether acupuncture is effective in treating DES.

Objective To investigate the eye-movement features of smooth pursuit in subjects at clinical high risk for psychosis.Methods sixty subjects at clinical high risk for psychosis and sixty healthy controls were recruited.The smooth pursuit tasks were assessed in both horizontal (0.4 Hz) and Lissajous (0.2 or 0.4 Hz) condition.The Wechsler Memory Scale-third edition and spatial span subtest were used to assess working memory.The difference of the smooth pursuit performance between the two groups and the relationship between smooth pursuit and working memory were analyzed.Results Subjects at clinical high risk for psychosis showed significantly lower Horizontal components for pursuit gain [Lissajous 0.2 Hz task (0.82±0.12) vs.(0.89±0.09),Lissajous 0.4 Hz task (0.78±0.13) vs.(0.84±0.14)],lower vertical components for pursuit gain [Lissajous 0.2 Hz task (0.80±0.14) vs.(0.86±0.12),Lissajous 0.4 Hz task (0.71±0.15)vs.(0.77±0.16)] and higher mean positional error [Lissajous 0.2 Hz task (37.00±19.10) vs.(30.45± 16.18),Lissajous 0.4 Hz task (44.18±19.70) vs.(37.61±16.26)] compared to healthy controls (P＜0.05).There was a significant correlation between pursuit gain and performance on Spatial Span (Horizontal components:r=0.361,P=0.005;vertical components:r=0.327,P=0.01 1) in the Subjects at clinical high risk for psychosis.Conclusions Subjects at clinical high risk for psychosis showed deficits in smooth pursuit,and the deficits were related to the working memory.

Objective:To observe the therapeutic effect of warm needling moxibustion for erectile dysfunction (ED).
Methods:A total of 46 eligible ED patients were randomized into a treatment group (n=24) and a control group (n=22). The treatment group was intervened by warm needling moxibustion while the control group by conventional acupuncture treatment, for a total of 4 courses. The therapeutic effect was evaluated by the international index of erectile function 5 (IIEF-5).
Results:After 4 courses of treatment, the overall effective rate was 91.3% in the treatment group (23 completed), versus 75.0% in the control group (20 completed), with a significant difference (P<0.05). After the treatment, the change of IIEF-5 score in the treatment group was significantly different from that in the control group (P<0.05).
Conclusion:Warm needling moxibustion can produce a more significant efficacy than conventional acupuncture in the treatment of ED.

Objective To evaluate the value of blood coagulation biomarkers in orthopaedic traumatic patients after surgery and analyze its diagnostic values for venous thrombosis embolism.Methods In thiscase control study, we consecutive enrolled 108 traumatic patients after surgery.54 patients have thrombosis and other 54 patients have no thrombosis.Blood was taken 3 -4 days after surgery.Routine coagulation screening test , FDP(fibrinogen/fibrin degradation products) , D dimer and new item such as TM( thrombomodulin) , TAT( thrombin-anti-thrombin complex) , t-PAIC( tissue-type plasminogen activator-plasminogen activator inhibitor complex),PIC(plasmin-anti-plasmin complex) were tested.The difference between groups of these biomarkers was compared, and then the receiver operation curve ( ROC) was drew to determine the diagnostic cut-off point and diagnostic performance.Results ALL blood coagulation biomarkers in orthopaedic traumatic patients after surgery were significantly increased.The group of patients with thrombosis have higher TM(9.04 ±2.06) IU/ml,t-PAIC(10.15 ±4.23) ng/ml, PIC(1.15 ±0.70)μg/ml, D dimer(5.31 ±5.10) ng/ml than group without thrombosis TM(7.50 ±1.70) IU/ml, t-PAIC (6.97 ±2.56)ng/ml, PIC(0.93 ±0.84)μg/ml,D dimer(2.35 ±2.12)ng/ml,and P=0.000 2,<0.000 1,<0.000 1,<0.000 1, respectively.However, TAT(4.79 ±4.32)ng/ml, (6.51 ±5.92)ng/ml, FDP (8.87 ±7.68 )μg/ml, ( 4.91 ±4.67 )μg/ml showed no difference between thrombosis groupand no thrombosis group, (P=0.212 3,0.050 8; respectively).The area under the ROC curve of TM, t-PAIC, PIC and D-dimer were 0.718 5,0.741 6,0.648 0,0.670 0, respectively; P values were <0.000 1,<0.000 1, 0.009 3,0.004 1, respectively; cut-off values were 11.15 IU/ml, 10.65 ng/ml, 1.36 μg/ml, 7.69 ng/ml, respectively;positive likelihood ratios were 9.00,11.29,3.66,14.60, respectively;specificity were 98.15%,96.23%, 90.20%, 97.96%, respectively; the diagnostic rates were 20.3%, 46.3%, 35.8%, 25.9%, respectively.Conclusions There were coagulation and fibrinolysis system activated in orthopaedic traumatic patients after surgery.TM, t-PAIC, PIC, D dimer were good biomarkers for the diagnosis of thrombosis after trauma surgery.TAT was not fit for screening thrombosis after surgery because of influence of anti-coagulation.
