ABSTRACT
Objective:To explore the related factors affecting the prognosis of patients with tardive dyskinesia, in order to find the risk factors of poor prognosis.Methods:A retrospective cohort study was implemented to collect the data of 113 patients with tardive dyskinesia from the movement disorders clinic of the Department of Neurology, Peking Union Medical College Hospital by telephone follow-up. The main variables studied included gender, age, educational level, living environment, job, cigarette smoking, alcohol drinking, hypertension, diabetes, medication type, interval from taking medicine to dyskinesia, course of dyskinesia and intervention measures. The data were analyzed by the statistical software SPSS 25.0. The quantitative data analysis was done by normality test and descriptive statistics, and the qualitative data analysis was done by χ 2 test or Fisher exact probability test. The variables with P≤0.01 in univariate analysis were included in multivariate Logistic regression analysis. Results:Among the 113 patients, 16 patients (14.16%) were cured, 27 patients (23.89%) had obvious improvement, 25 patients (22.12%) had slight improvement, 26 patients (23.01%) had no obvious change, 15 patients (13.27%) had slight deterioration, and 4 patients (3.54%) had obvious deterioration. The good prognosis rate was 60.18%, and the poor prognosis rate was 39.82%. In single factor analysis, the related factors for poor prognosis included age>52 years (χ 2=15.07, P<0.001), educational level in secondary schools and below (χ 2=8.58, P=0.003), physical labor (χ 2=4.66, P=0.031), hypertension (χ 2 = 16.38, P<0.001), diabetes mellitus (χ 2=6.06, P=0.011), dyskinesia caused by first-generation antipsychotics, calcium channel blocker or flupentixol/melitracen tablets ( P<0.001), and the duration of dyskinesia more than 2 years (χ 2 =7.05, P=0.008). Multivariate Logistic regression analysis showed that the independent risk factors for poor prognosis of tardive dyskinesia included hypertension ( OR=3.60, 95% CI 1.17-11.05, P=0.025) and dyskinesia caused by first-generation antipsychotics, calcium channel blocker or flupentixol/melitracen tablets ( OR=3.14, 95% CI 1.21-8.16, P=0.019). Conclusions:Most patients with tardive dyskinesia have a good prognosis. Hypertension and dyskinesia caused by first-generation antipsychotics, calcium channel blocker or flupentixol/melitracen tablets are independent risk factors for poor prognosis.
ABSTRACT
ObjectiveTo analyze the utilization of outcome indexes and other trial design elements in randomized controlled trials （RCTs） of Chinese medicine for diabetic kidney disease （DKD） and provide a basis for the design of clinical trials and the development of core outcome index sets for Chinese medicine treatment of DKD. MethodSeven medical databases （CNKI， Wanfang Data， VIP， SinoMed， etc.） and two clinical trial registration centers （clinicaltrials.gov and chinadrugtrials.org.cn） were searched for RCTs of Chinese medicine for DKD published in the past 5 years. The included studies were assessed for risk of bias using the Cochrane Handbook for Systematic Reviews of Interventions， and the outcome indexes and other trial design elements were statistically analyzed. ResultNinety-seven RCTs were enrolled， including five trial registration protocols. The overall risk of bias was found to be high in the included studies. Stage Ⅲ DKD （36 studies， 41.38%） and the Qi-Yin deficiency with blood stasis syndrome （16 studies， 26.23%） were the top DKD stage and traditional Chinese medicine （TCM） syndrome， respectively. The treatment duration ranged from 2 weeks to 96 weeks， with 12 weeks being the most common duration （52 studies， 56.52%）. A total of 152 outcome indexes were used in 92 RCTs and five registered trials， with a frequency of 1 040 times. These indexes were classified into eight categories： Laboratory tests （blood）， laboratory tests （urine）， clinical efficacy， TCM syndrome score， quality of life scales， vital signs， other indexes， and other events. The most frequently used outcome indexes were serum creatinine （68 times， 70.10%）， clinical response rate （55 times， 56.70%）， fasting blood glucose （51 times， 52.58%）， blood urea nitrogen （48 times， 49.48%）， total cholesterol （47 times， 48.45%）， and 24-hour urinary protein excretion （43 times， 44.33%）. Safety indexes were used in 56 RCTs and two registered trials， with 53 different indexes and a frequency of 227 times. The most frequently used safety indexes were adverse reactions （49 times， 84.48%）， liver function （28 times， 48.28%）， complete blood count （24 times， 41.38%）， electrocardiogram （17 times， 29.31%）， and urinalysis （14 times， 24.14%）. Ten RCTs and five registered trials reported primary outcome indexes， and 54 RCTs reported clinical response rates. ConclusionThe current design of outcome indexes in RCTs of Chinese medicine for DKD is not standardized. In the future， efforts should be made to develop core outcome index sets that highlight the characteristics of TCM， improve the quality of clinical research， and enhance the applicability of trial results.

ABSTRACT
BACKGROUND:Now experimental and clinical research on suitable bone substitutes for alveolar bone defects after dental implantation is an issue of concern.OBJECTIVE:To study the therapeutic effect of titanium core/bone morphogenetic protein (BMP) composite material on alveolar bone defects after immediate implant placement.METHODS:Twenty-four New Zealand rabbits were randomly assigned into normal group (no intervention),experimental group or control group.Animal models of bone femoral greater trochanter defect were made in the experimental and control groups.Dental implant and titanium core/BMP composite material were implanted in the experimental group,while dental implant and titanium core were implanted in the control group.Percentage of CD4+,CD8+ T lymphocytes,natural killer cell activity and interleukin 2 level were detected at postoperative 4 weeks;bone mineral density and osteogenesis around the implant were detected at postoperative 16 weeks through X-ray and histological examinations.RESULTS AND CONCLUSION:X-ray results showed that the bone mineral density in the experimental group was significantly higher than that in the control group (P ＜ 0.05).Histological results showed that in the experimental group,different degrees of cell lysis around the composite,more bone cells and bone matrices were found,implant-bone osseointegration formed well,and red-dyed mature bone tissues were detective inside the implant.Compared with the experimental group,lower number of bone cells and fibrocytes were found in the control group.Additionally,the percentage of CD4+ and CD8+ T lymphocytes,natural killer cell activity and interleukin 2 level in the experimental group were significantly lower than those in the control group (P ＜ 0.05).To conclude,the titanium core/BMP composite material can effectively repair alveolar bone defects after immediate implant placement to guide the growth of bone cells.
ABSTRACT
Objective To investigate whether the combination of maintenance hemodialysis (MHD) with hemoperfusion (HP) could improve the left ventricular structure and function of MHD patients with resistant hypertension. Methods This study was a prospective, randomized, controlled clinical trial. 65 MHD patients with resistant hypertension of our hospital were enrolled and then randomly divided into Group HD+HP and Group HD. The follow-up study was 12 months. The major outcome measures were related to the cardiac structure and function, and the serum inflammatory factors. Results No statistical differences of related factors such as blood pressure and cardiac function was observed in HD group. The serum concentration of inflammatory factors was higher after one-year HD treatment alone. But the serum concentration of inflammatory related factors , blood pressure, cardiac function and related indexes were lower in HD + HP than in Group HD (P < 0.05);HD + HP group had higher ejection fraction (EF) and SV, which demonstrated the improved cardiac function (P < 0.05). Conclusions HD + HP was superior to HD in the treatment in alleviating cardiac after-load and improving the left ventricular structure and function of MHD patients with resistance hypertension.
