Conclusions The survival probability of TRPV1 -/-mice is better than that of ASIC3 -/-mice.There is no significant gender difference in the two strains of mice.

87 periodontally healthy young volunteers paticipated in the study.4 clinical parameters were measured:Gingival thickness (GT),gingival width (GW),papilla height (PH) and crown width/crown length ratio (CW/CL).Cluster analysis was employed to identify the periodontal phenotypes.As a result,the periodontal phenotype of maxillary anterior tooth was classified as thin fan type (Ⅰ,n =31),thick and wide type(Ⅲ,n =8) and intermediate type(Ⅱ,n =48) in Han Chinese.

Objective:To establish a scoring system for preoperative prediction of the malignant potential of gastric stromal tumors based on gastroscopic and endoscopic ultrasound features, along with validation.Methods:A total of 286 patients who were treated in Jiangsu Province Hospital of Chinese Medicine from January 1, 2017 to December 31, 2023 and diagnosed as having gastric stromal tumors by postoperative pathology were enrolled in the modeling group. According to National Institutes of Health classification system, 227 very-low/low-risk patients were classified into the low malignant potential (LMP) group, and the 59 intermediate/high-risk patients into the high malignant potential (HMP) group. LASSO regression analysis was performed to identify predictive factors for HMP gastric stromal tumors, and a nomogram prediction model was developed. Internal validation using the Bootstrap method was performed on the modeling group, and external validation was performed on data from 85 patients who were treated and diagnosed as having gastric stromal tumors by postoperative pathology in Taizhou People's Hospital from January 1, 2021 to December 31, 2023. The receiver operator characteristic (ROC) curves, calibration curves, and decision curve analyses were employed in both the modeling and external validation groups.Results:Tumor size (coef=0.755), tumor shape (coef=0.015), tumor location (coef=0.008), growth pattern (coef=-0.026), cystic change (coef=0.685), and surface unceration change (coef=-0.545) were the independent predictive factors for HMP gastric stromal tumors. The nomogram-based prediction model constructed using these factors achieved an area under the ROC curve of 0.959 (95% CI: 0.898-0.903) in the modeling group and 0.959 (95% CI: 0.857-1.000) in the external validation group. The model demonstrated good accuracy (0.917) and a Kappa value of 0.737 in internal validation. Calibration curve and decision curve analyses indicated strong calibration and high net benefit in both the modeling and the external validation groups. Conclusion:Tumor size, tumor shape, tumor location, growth pattern, cystic change, and surface ulceration change are independent predictive factors for HMP gastric stromal tumors. The nomogram model developed based on these factors offers effective and convenient visualization for clinicians to predict the malignant potential of gastric stromal tumors preoperatively.

Objective:To analyze clinical characteristics of neurosyphilis patients with abnormal mental behaviors as the initial symptom, and to provide a reference for clinical classification of, as well as outcome prediction and efficacy monitoring in neurosyphilis.Methods:Clinical data were collected from 67 HIV-negative neurosyphilis patients with abnormal mental behaviors as the initial symptom in the Second Affiliated Hospital of Soochow University from November 2012 to November 2019, and retrospectively analyzed. Statistical analysis was carried out by using t test. Results:Among the 67 patients, 52 (77.6%) were males, and 15 (22.4%) were females; there were 63 (94.0%) middle-aged and elderly patients and 4 (6.0%) adolescent patients; 38 (56.7%) patients were diagnosed with progressive general paresis, 21 (31.3%) with meningovascular neurosyphilis, 1 (1.5%) with meningeal neurosyphilis, 3 (4.5%) with tabes dorsalis, and 4 (6.0%) with mixed-type neurosyphilis. As laboratory examination showed, 67 patients all presented with positive serum rapid plasma reagin (RPR) test, serum Treponema pallidum particle agglutination (TPPA) test, and cerebrospinal fluid TPPA test, 55 (82.1%) had positive cerebrospinal fluid RPR test, 47 (70.1%) had elevated cerebrospinal fluid protein levels of > 0.45 g/L, 50 (74.6%) had increased white blood cell counts of > 8 ×10 6/L in cerebrospinal fluids, and 28 (41.8%) had elevated IgG levels in cerebrospinal fluids. Magnetic resonance imaging of the brain revealed multiple ischemic foci in 21 (31.3%) cases, multiple leukodystrophy in 17 (25.4%) , cerebral atrophy in 15 (22.4%) , infarction in 8 (11.9%) , and encephalitis-like changes in 2 (3.0%) . Of the 67 patients, 48 were treated with penicillin in aqueous solutions, 15 with ceftriaxone, and 4 with doxycycline. Six months later, the follow-up showed that 46 (68.7%) patients responded to the treatment, and the early course of disease was significantly shorter in the highly responsive group than in the poorly responsive group ( P < 0.05) . Conclusion:The middle-aged and elderly males were predominant in the neurosyphilis patients with abnormal mental behaviors as the initial symptom, magnetic resonance imaging is helpful for clinical classification and prognosis prediction of neurosyphilis, and early and standardized antisyphilitic treatment can markedly improve the prognosis of patients.

Objective To analysis the clinical pathway management efficiency under different DRG groups, for a basis for further optimizing clinical pathway management. Methods The retrospective analysis method was used to compare the average length of stay, sub-average costs, and drug proportions of patients with different DRGs in the same clinical pathway. Shapiro-Wilk was used to detect the normality of the samples, t test was used to analyze measurement data conformed to the normal distribution, non-parametric test was used to analyze the abnormal distribution data, and enumeration data was detected by using chi-square test. Results For patients with a clinical pathway of bronchial pneumonia, patients with severe complications and concomitant symptoms had no significant difference in mean hospitalization and sub-costs, regardless of whether they completed or entered the clinical pathway ( P >0.05). For the other two DRG patients, the difference between the average length of stay, sub-average costs, and the proportion of medications for patients who completed the clinical pathway and withdrew from or did not complete the clinical pathway was significant(P<0.05). In the severe surgical group, the length of stay and average cost for patients who completed the clinical pathway were lower than those who exited or did not enter the clinical pathway(P<0.05). Conclusions Patients with different severity of DRGs should be cautious when they are enrolled in the clinical pathway.

Objective To analyze the differences in hospitalization days and costs of patients with acute cholecystitis in different departments or diagnosis related groups ( DRGs ), and provide scientific references for clinical medical management. Methods All the medical record homepages of the patients with acute cholecystitis were selected from a tertiary hospital from January 2017 to December 2017. The hospital analysis system of DRGs was used to calculate the classification results of DRGs. The Kruskal-Wallis H test was used to analyze the differences in hospital stays and costs between different DRGs or departments. Results The average length of stay was the shortest and the hospitalization cost in the department of hepatobiliary surgery was lower than other departments among patients with surgery and non-surgical(all P<0.05); The average length of stay at the department of hepatobiliary surgery was lower than the same other DRGs groups, namely the department of digestive medicine and gastrointestinal surgery(all P<0.05). There was no significant difference in the cost of " acute biliary tract disease with complications" between the various departments(P>0.05). The average cost in the department of hepatobiliary surgery was the lowest, and the average cost of gastrointestinal surgery was the highest in two DRGs of " acute biliary disease without complications and concomitant symptoms" and " laparoscopic cholecystectomy without common bile duct exploration" ( all P < 0.05 ). Conclusions Department of hepatobiliary surgery was better than other departments in the treatment of acute cholecystitis. Medical institutions should follow the principle of special treatment to reduce interdisciplinary patients and improve the professional competitiveness of the department.

OBJECTIVE: To study the prevalence of metabolic syndrome( MS),and disease components among teaching staffs in a traditional Chinese medicine college.METHODS: A total of 993 teaching staffs of a traditional Chinese medicine college who participated physical health examination were selected as study subjects by convenience sampling method.The detection of MS,characteristics of MS related diseases and aggregation were analyzed.RESULTS: The incidence of MS was 19.2%( 191/993).It showed a linear upward trend with the increase of age( P < 0.01).The incidence of MS in male members was obviously higher than that in female members( 28.1% vs 9.5%,P < 0.01).The risk indexes of MS in staffs,including overweight and/or obesity, hyperglycemia, hypertension, triglyceride( TG) abnormality and high-density lipoprotein cholesterol( HDL-C) abnormality were 3.44,13.61,9.94,14.72 and 12.06 times of those with normal indexes respectively.The abnormal ratio of hyperglycemia,hypertension and TG was the highest( 13.7%) in different types of MS,and the incidence of MS on staffs was the highest( odds ratio 5.86).CONCLUSION: The detection rate of MS showed an upward trend with the increase of age among teaching staffs in this traditional Chinese medicine college,and there is a gender difference.TG and HDL-C abnormality,hypertension and hyperglycemia are the key points of prevention and treatment of MS in this population.
