Objective To study the levels of serum cytokines in schizophrenic patients and their changes in antipsychotic medica-tion treatment .Methods The levels of serum cytokines including IL-10 ,IL-6 ,IL-13 ,IL-4 ,IFN ,TNF-α,IL-1a and IL-1RA were de-tected in 34 healthy adults and 53 schizophrenia patients by adopting the flow fluorescence method .Results The serum levels of IL-6 ,IL10 and TNF-αbefore treatment in schizophrenic patients were significantly higher than those in the control group (P<0 .05) . After treatment ,the levels of serum IL-1a ,IL-6 and TNF-α in schizophrenic patients were significantly lower than those before treatment(P<0 .05) .Conclusion Serum IL-6 and TNF-α levels are correlated with the disease condition of schizophrenia .IL-10 plays a role in early anti-inflammation of schizophrenia .

Objective: To investigate the protective effect of glucagon-like peptid-1 (GLP-1) against cardiac microvascular endothelial cell (CMECs) injured by high glucose. Methods: CMECs were isolated and cultured. Superoxide assay kit and dihydroethidine (DHE) staining were used to assess oxidative stress. TUNEL staining and caspase 3 expression were used to assess the apoptosis of CMECs. H89 was used to inhibit cAMP/PKA pathway; fasudil was used to inhibit Rho/ROCK pathway. The protein expressions of Rho, ROCK were examined by Western blot analysis. Results: High glucose increased the production of ROS, the activity of NADPH, the apoptosis rate and the expression level of Rho/ROCK in CMECs, while GLP-1 decreased high glucose-induced ROS production, the NADPH activity and the apoptosis rate and the expression level of Rho/ROCK in CMECs, the difference were statistically significant (. P<0.05). Conclusions: GLP-1 could protect the cardiac microvessels against oxidative stress and apoptosis. The protective effects of GLP-1 are dependent on downstream inhibition of Rho through a cAMP/PKA-dependent manner, resulting in a subsequent decrease in the expression of NADPH oxidase.

ObjectiveTo evaluate the effect of standardized blood pressure measurement in consulting room （SBPM） model on blood pressure screening of non-hypertensive patients in community. MethodsFour communities were randomly selected from Fengxian District of Shanghai， and non-hypertensive patients in the communities were included for screening. Based on the communities， participants were further classified into the intervention group and control group. A one-year intervention study was conducted from January 1， 2021 to December 31， 2021. The intervention group received the intervention measures of standardized measurement， and the control group remained the routine measurement. The distribution of blood pressure values and last digit of the values between the intervention group and control group were tested using Chi-square test and normality test. Then changes in abnormal blood pressure rate before and after the intervention were determined by double difference method. Statistical analysis was performed using SPSS 20.0. ResultsA total of 15 368 participants were included in the intervention group， and 19 811 participants in the control group. After the intervention， range of the last digit of blood pressure values in the intervention group was 9.55%‒10.41%， of which that of systolic and diastolic blood pressure were equally distributed （P=0.932 and 0.871， respectively）. The range of the last digit in the control group was 1.31%‒42.58%， of which that of systolic and diastolic blood pressure showed unequal distribution （P<0.001）. Through one-year standardized measurement intervention， the abnormal rate of blood pressure in the intervention group was 26.29%， which was 7.61 times as high as that in the control group （OR=7.55， 95%CI： 6.75‒8.57， P<0.001）. ConclusionStandardized blood pressure measurement in consulting room is suitable for the screening of blood pressure measurement in community， which has higher data quality than that of routine measurement.

OBJECTIVETo investigate the safety and efficacy of minimally invasive achilles tendon lengthening and system rehabilitation for the treatment of contracture of achilles tendon.

METHODSFrom January 2002 to December 2010, 27 patients (31 feet) with contracture of achilles tendon were treated with minimally invasive achilles tendon lengthening and system rehabilitation. There were 11 males and 16 females with an average age of 35.5 years (ranged 3 to 65 years). Right foot was in 13 cases, left foot was in 10 cases, both feet were in 4 cases. Course of disease was from 1 to 5 years with an average of 2.3 years. The cause of contracture included postoperative complication of tibia fractures treated with intramedullary nailing in 7 feet, sequelae of lower leg compartment syndrome in 11 feet, congenital talipes equinovarus in 13 feet (both feet in 4). Before operation, all the patients walked with limping, plantar flexion anomaly was from 15 degrees to 50 degrees with an average of 35.5 degrees. The strength of quadriceps muscle of thigh was grade V in 27 feet, grade IV in 4 feet, the strength of musculus triceps surae was grade V in 24 feet, grade IV in 7 feet.

RESULTSAll the patients were followed-up for 6-24 months with an average of 11.3 months. According to standard of Arner-Lindholm to evaluate function of ankle joint, 29 feet obtained excellent results and 2 feet good. No infection, re-rupture or re-contracture was found.

CONCLUSIONMinimally invasive achilles tendon lengthening and system rehabilitation in treating contracture of achilles tendon has advantage such as simple operation, less complication, lower recurrence rate, which is favourable for thoroughly rehabilitation of patients. But, the case in which the strength of quadriceps muscle of thigh or musculus triceps surae still less than grade III after preoperative rehabilitation care should not choose the method.

OBJECTIVES: To examine the reliability and accuracy of Walker's model for estimating the sex of Han adults in western China by using cranium three-dimensional (3D) CT reconstruction, and to study the suitable cranial sex estimation model for Han people in western China. METHODS: A total of 576 cranial CT 3D reconstructed images from Hanzhong Hospital in Shaanxi Province from 2017 to 2021 were collected. These images were divided into the experimental group with 486 samples and the validation group with 90 samples. Walker's model was used by observer 1 to estimate the sex of experimental group samples. The logistic function applicable to Han people in western China was corrected by observer 1. The 90 samples in the validation group were scored and substituted into the modified logistic function to complete the back substitution test by observer 1, 2 and 3. RESULTS: The accuracy of sex estimation of Han adults in western China was 63.2%-77.2% by applying Walker's model. The accuracy of modified logistic function was 82.9%. The accuracy of sex estimation through back substitution test by 3 observers was 75.6%-91.1%, with a Kappa value of 0.689 (P<0.05) for inter-observer consistency and 0.874 (P<0.05) for intra-observer consistency. CONCLUSIONS There are great differences in bone characteristics among people from different regions. The modified logistic function can achieve higher accuracy in Han adults in western China.
