AIM: To observe the clinical effect of the tonifying kidney pills with mingmuwuzi treating evaporative dry eyes.METHODS: This study adopted the positive drug control,prospective study,random number remainder grouping method to 65 cases of outpatient patients diagnosed with evaporative dry eyes which were divided into the treatment group 32 cases (64 eyes) and the control group 33 cases (66 eyes).The treatment group took the decoction of kidney pills with mingmuwuzi,combined with sodium hyaluronate eye drops.The control group simply use sodium hyaluronate eye drops,both group were set to 4wk for a course of treatment.To observe the symptoms and signs of two groups before and after the treatment,the change of the evaluation index and curative effect were evaluated.RESULTS: The effectiveness of the treatment group was 87.5%,the control group was 78.8%,the difference was statistically significant (z=-3.149,P<0.05).CONCLUSION: The treatment of the kidney pills with mingmuwuzi combined with sodium hyaluronate eye drops to evaporative dry eyes is more effective than the simple use of sodium hyaluronate eye drops.

OBJECTIVE: To realize the automated assessment of the levels of epiphysis of distal radius and ulna by support vector machine (SVM). METHODS: The X-ray films of the left wrist joints were taken from 140 teenagers aged from 11 to 19 years old as training samples. The levels of epiphysis of distal radius and ulna were divided into five developmental levels. Each level contained 28 samples. Another 35 cases were selected as independent verifying samples. SVM classification models of the five developmental levels of epiphysis of distal radius and ulna were established. The internal cross validation was made by leave one out cross validation (LOOCV), while the external validation was made by histogram of oriented gradient (HOG), and then the accuracy (PA) of testing results was calculated, respectively. RESULTS: The PA of SVM, LOOCV and HOG of distal radius epiphyseal level were 100%, 78.6%, and 82.8%, respectively; whereas the PA of SVM, LOOCV and HOG of distal ulna epiphyseal level were 100.0%, 80.0% and 88.6%, respectively. CONCLUSION The SVM-based automatic models of the growth stage of distal ra- dius and ulna appear to have certain feasibility, and may provide a foundation for software development of bone age assessment by forensic medicine.

Abstract: Objective　To analyze the epidemiological characteristics of public health emergencies in Xishuangbanna Dai Autonomous Prefecture from 2012 to 2021, and to provide reference for formulating relevant prevention and control measures. Methods　The data of public health emergencies reported in Xishuangbanna from 2012 to 2021 were collected and analyzed through the China Disease Prevention and Control Information System. Results A total of 78 public health emergencies (including "Unrated" events) were reported in Xishuangbanna from 2012 to 2021. The highest 21 cases and the lowest 3 cases were reported every year. A total of 1 0374 cases were reported in 78 public health emergencies, involving a population of 1 703 049, with a morbidity of 609.14/100 000, 24 deaths, mortality of 1.41/100 000 and fatality rate of 231.35/100 000. The event level was mainly "general (level Ⅳ)" with 52 incidents, accounting for 66.67%, and 17 incidents of "major (level Ⅲ)", accounting for 21.79%. 51 cases were mainly infectious diseases, accounting for 65.39%. The peak periods for incidents were May-July and November-February of the next year; there were 39 incidents in schools, accounting for 50%, followed by 20 incidents in families, accounting for 25.64%. The top three reported cases were food poisoning (32.05%), chicken pox 17 (21.79%) and dengue fever 10 (12.82%). Among the 24 deaths in public health emergencies, 22 were caused by food poisoning. Wild bacteria poisoning and alcohol poisoning were the main causes of food poisoning, accounting for 45.83% and 37.5% of the total deaths, respectively. Conclusion Infectious diseases, especially respiratory diseases and food poisoning are the focus of the prevention and control of public health emergencies in Xishuangbanna Dai Autonomous Prefecture, of which Schools and families should be pay close attention. Plague, a Class A infectious disease, caused by the bacterium Yersinia pestis has occurred in two inter-animal outbreaks in 10 years and spread to the population, which should be of great concern.

Objective To study the distribution and related factors of curative care expenditure (CCE) of injury in Gansu Province in 2017. Methods Based on the "A System of Health Accounts 2011 (SHA 2011)", the curative care expenditure of injury in Gansu Province was calculated and analyzed. The five?stage stratified cluster sampling method was adopted to extract 149 medical and health institutions, 120 township hospitals (including community health service centers), 150 individual clinics and 600 village clinics (including community health service stations). The top?down allocation method was used to calculate the cost of injury treatment in Gansu Province, and the influencing factors were analyzed by multiple linear regression. Results In 2017, the CCE of injury in Gansu province was 3.831 billion yuan, and the expense in general hospitals was 2.708 billion yuan. Among them, the cost of lower limb injury and head injury were 1.090 and 0.847 billion yuan. People aged 40 to 69 years old spent 1.901 billion yuan on injury treatment, and the CCE of injury treatment for men and women were 2.422 and 1.409 billion yuan respectively. The results of multiple linear regression showed that hospitalization expenditure was significantly associated with length of stay, operation, hospital grade, age, payment method and gender (P<0.001). Conclusion The economic burden of injury in Gansu Province is relatively heavy, so it is necessary to focus on preventions for different groups and costly injury sites.

Objectives To investigate the characteristics of changes in serum metabolic profile before and after resection of carcinoma tissues to establish a disease distinguishing model,to analyze the changing trend of characteristic metabolites,and to determine the molecular mechanism and potential clinical value of characteristic metabolic markers for HBV-related liver cancer.Methods Ultraperformance liquid chromatography-mass spectrometry (UPLC-MS) was used to analyze the serum metabolites of 15 patients with hepatocellular carcinoma (HCC) before and after partial hepatectomy and on 25 healthy volunteers.The pattern recognition method and nonparametric test analyzes were used to analyze the data and to identify the specific metabolites and their changes after resection of carcinoma tissues.Results We established the principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) disease distinguishing model for HCC patients before and after operation as against the healthy volunteers.To distinguish between the liver cancer group and the normal control group,27 characteristic metabolites were selected from the patients before and after resection of carcinoma tissues.Eight moved towards the normal control after resection of carcinoma tissues.This indicated that liver carcinoma was an important impacting factor for these metabolites.Finally,7 metabolites were identified,and these metabolites had high diagnostic value as shown on ROC curves.Conclusions Through serum metabolic profiling of patients before and after resection of carcinoma tissues,a high correlation between metabolism and hepatocellular carcinoma was found.Researches on endogenous metabolites and pathways in liver diseases will provide a better understanding of the molecular mechanisms and provide further directions for clinical diagnosis and treatment.

AIM:To study the feasibility of recombinant adeno-associated virus(rAAV)as a vector to transfer the green fluorescent protein(GFP)gene as a target gene into rabbit retina.METHODS:Intravitreal injection of rAAV-gfp was performed in either eye for each rabbit with the other eye taken as control.At the 3rd,7th,and 14th day after injection,the eyeballs were removed,and the retinas were flat-mounted on glass slides to inspect the retinal fluorescence,respectively.RESULTS:After intravitreal injection of rAAV-gfp,the presence of fluorescent spots in the cytoplasm of retinal cells indicated that GFP gene was efficiently transferred and expressed in the rabbit retina.CONCLUSION:Recombinant adeno-associated virus is a reliable and simple vector for transferring target gene,e.g.,GFP gene,to the retina.
