ObjectiveTo investigate the effects of repetitive transcranial magnetic stimulation （rTMS） on the efficacy and cognitive function of adolescents with depression. MethodsA total of sixty adolescent depression patients who met the diagnostic criteria of the International Classification of Diseases， tenth edition （ICD-10） and were admitted to the psychological outpatient clinic of the Affiliated Hospital of North China University of Technology from September 2021 to March 2022 were selected for the study， and the random number table method was used to divide the study group （escitalopram oxalate combined with rTMS treatment） and a control group （escitalopram oxalate combined with rTMS pseudo-stimulation treatment） of 30 cases each， and both groups were treated for 4 weeks. Before treatment and at 1， 2， 3 and 4 weeks of treatment， patients' depressive symptoms were assessed using the scores and subtraction rates of the Hamilton Depression Scale-24 item （HAMD-24）， and before treatment and after 4 weeks of treatment， cognitive function was assessed using the Motion Screening Task （MOT）， Rule Switch Task （RST） and Delayed Matching-to-Sample （DMS） task of the Zhiyun Neuropsychological Automated Test System assessment. Adverse effects during treatment were recorded in both groups. ResultsRepeated measures ANOVA results showed statistically significant time main effects， group main effects， and the interaction between the two groups for HAMD-24 scores before treatment and after 1， 2， 3 and 4 weeks of treatment in patients （F=522.021， 39.905， 26.412， P<0.05）. Individual effect analysis showed statistically significant differences in HAMD-24 scores between the two groups after 2， 3 and 4 weeks of treatment （t=-12.784~-2.776， P<0.01）. After 4 weeks of treatment， the total effective rate of treatment in the study group was higher than that in the control group （93.33% vs. 73.33%， χ²=4.320， P<0.05）， and the differences in each indicator of RST and DMS between the two groups were statistically significant compared with those before treatment （t=-5.616~9.135， P<0.05 or 0.01）， and the differences between the two groups were statistically significant （t=-4.823~5.518， P<0.05 or 0.01）. ConclusionrTMS may help improve depressive symptoms as well as cognitive function in adolescents with depression.

Objective:To investigate the incidence of venous thromboembolic disease (VTE) in urological inpatients during perioperation.Methods:The clinical data of 7 988 inpatients admitted to the Department of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January to December 2019 were analyzed retrospectively. The cohort included 5 657 males and 2 331 females. The average age of the enrolled patients was (56.3±15.8) years old, and the body mass index was (23.8±3.2) kg/m 2. There were 1 628 malignant tumors patients and 6 360 non-malignant tumors patients in the cohort. Of all the patients, 7 725 cases received surgical treatment. All patients were scored with the Caprini Risk Assessment Model (2005) after admission and 1 655 cases were classified as very low risk, 2 940 cases were low risk, 2 922 cases were medium risk, 345 cases were high risk and 126 cases were very high risk. Patients with Caprini score ≥ 2 and/or clinical symptoms were examined by venous color Doppler ultrasound. CT pulmonary angiography was performed for patients with chest pain, chest tightness, decreased blood oxygen saturation and other symptoms suspected of pulmonary embolism according to clinical judgment to screen the incidence of VTE. Results:Among the 7 988 cases, 180 cases (2.25%, 180/7 988) with VTE were found by preoperative examination, including 1 case (0.01%, 1/7 988) with pulmonary embolism. There were 199 new cases with VTE after operation, and the incidence of new VTE after operation was 2.58% (199/7 725). Among them, pulmonary embolism was found in 7 cases, with a incidence of 0.09% (7/7 725). Only 7.92% (30/379) of the VTE patients had VTE-related symptoms. The operations with higher incidence of VTE were radical cystectomy, nephroureterectomy, radical prostatectomy and radical nephrectomy, with the incidence of 11.61% (13/112), 10.87 (10/92), 8.25% (16/194) and 6.16% (22/357) respectively.Conclusions:The incidence of VTE in hospitalized patients with urinary surgery in this study is much higher than previously reported. Most of the patients with VTE are asymptomatic. The operations with high incidence of VTE after operation are radical cystectomy, nephroureterectomy, radical prostatectomy and radical nephrectomy. Therefore, it is necessary to carry out VTE screening for hospitalized patients in urology department, which is helpful to realize early intervention of VTE and reduce the risk of VTE progression and pulmonary embolism.

Objective:To explore the clinical characteristics of autosomal dominant polycystic kidney disease (ADPKD).Methods:Clinical data of 103 patients with ADPKD first admitted to Renmin Hospital of Wuhan University from July 2017 to April 2021 were retrospectively analyzed. The clinical characteristics of patients in different renal function stages were analyzed, and multiple linear regression analysis was used to analyze the factors reflecting the severity of the disease.Results:Among the 103 patients with ADPKD, there were 49 males (47.6%), aged (51.23±10.99) years old. The extrarenal manifestation was mainly polycystic liver (64/71). The main clinical symptoms were gross hematuria (25 cases, 24.3%), lumbar distend and pain (37 cases, 35.9%) and hypertension (69 cases, 67.0%), appearing in the whole course of the disease. Early treatment was mainly drug conservative treatments (58 cases, 56.3%), followed by renal cyst aspiration (34 cases, 33.0%), and surgical treatments (11 cases, 10.7%). Patients in chronic kidney disease (CKD) stage 5 were mainly treated with conservative treatments (28/34). Laboratory examination results showed that hemoglobin, platelet, lymphocyte percentage and albumin in CKD stage 4-5 were lower than those in CKD stage 1-3 (all P<0.05) ; prothrombin time (PT), PT-international standardized ratio and plasma osmotic concentration in CKD stage 4-5 were higher than those in CKD stage 1-3 (all P<0.05). Multiple linear regression analysis showed that hemoglobin ( β=0.249, P=0.005), platelet ( β=0.207, P=0.005), lymphocyte percentage ( β=0.305, P<0.001) and plasma osmotic concentration ( β=-0.362, P<0.001) were correlated with estimated glomerular filtration rate. Conclusions:The clinical manifestations of ADPKD patients are hypertension, lumbar distend and pain, and gross hematuria, which can run through the whole stage of CKD. Polycystic liver is more common in extrarenal system. Hemoglobin, platelets, lymphocyte percentage and concentration osmotic concentration may be related to the disease progression of ADPKD.

Objective To investigate the status quo of illness uncertainty and role adaptation in mothers with babies in Neonatal Intensive Care Unit (NICU) and to explore the correlation between the two. Methods Totally 300 mothers with babies admitted in the NICU of 3 Class Ⅲ Grade A hospitals in Wenzhou between April and November 2017 were selected by convenient sampling. The demographic characteristics questionnaire for parents with babies in NICU, the Mishel Illness Uncertainty Scale for Parents and the Role Adaptation Questionnaire were used to investigate the mothers. The univariate analysis, Pearson correlation analysis and multiple stepwise regression analysis were employed to explore the influencing factors to their role adaptation. A total of 300 questionnaires were distributed, and 273 valid questionnaires were collected. Results The total score of the Mischel Illness Uncertainty Scale in the 273 mothers with babies in NICU was (98.58±11.78), and their score in role adaptation was (59.84±8.16). Illness uncertainty and role adaptation were negatively correlated in the mothers with babies in NICU (r=-0.230, P＜0.05). According to the multiple stepwise regression analysis, complexity and information famine in illness uncertainty of mothers were the influencing factors to the mothers' role adaptation. Conclusions The level of role adaptation in mothers with babies in NICU is low, and their illness uncertainty may be used to predict their role adaptation. NICU nursing staff should take targeted measures to reduce the mothers' illness uncertainty and improve their role adaptation.

OBJECTIVETo prepare freeze-dried long-circulation oridonin liposomes with optimized parameters.

METHODSEthanol injection method followed by freeze-drying was used to prepare the liposomes. Sephadex column was used to purify liposomes. Effects of formulation factors on entrapment efficiency of long-circulation oridonin liposomes were studied. The particle size, distribution and in vitro release were determined. Pharmacokinetics of oridonin liposomes in rats was determined by HPLC and the pharmacokinetic parameters calculated by Kinetica(TM) software were compared with conventional oridonin liposomes and solution.

RESULTSThe optimized lipid formulation for long-circulation liposomes was composed of soy lecithin, cholesterol and DSPE-PEG 2000 with a ratio of 1:0.5:1.8(w/w). The ratio of drug to lipid was 1:6. Freeze-drying protectant was a mixture of glucose and mannitol (3:1). The entrapment efficiency (EE) of long-circulation oridonin liposomes was about 65%. The particle size of liposomes after hydrolyzation was 164 nm with good DPI. The liposomes showed a sustained drug release in vitro. Intravenous injected oridonin fitted with two-compartment pharmacokinetic model. The MRT of long-circulation liposomes was 2 times and 6 times and AUC was about 2 times and 3 times of conventional liposomes and oridonin solution, respectively.

CONCLUSIONFreeze-dried liposomes with high EE have been obtained by the proposed approach. This long-circulation liposomes extend oridonin half time and significantly increase AUC in rats.

AIM: To study the effect and the mechanism of crenulatin, an effective constituent of Chinese traditional medicine, on apoptosis of cerebral microvascular endothelial cells. METHODS: The following terminal concentrations of crenulatin were used in the study: 25 mg/L and 100 mg/L. Apoptosis of mouse cerebral microvascular endothelial cells (bEnd. 3 cell line) was evaluated by flow cytometer, immunocytochemical assay (Fas, Bcl - 2) and Western blotting (caspase - 3) after culture for 24 h. RESULTS: Compared with control group, apoptosis of bEnd. 3 cells in 25 mg/L group was significantly inhibited ( P ＜0.05), but apoptosis in the 100 mg/L group was significantly increased (P ＜ 0.05). In apoptosis inhibited group, the Fas immunocytochemical staining was weaker, the positive cells were significantly decreased ( P ＜ 0.05) and caspase - 3 expression was decreased compared with control group; however, the Bcl - 2 staining was stronger and the positive cells were significantly increased ( P ＜ 0.05). On the other hand, in apoptosis increased group ( 100 mg/L group), the changes were just opposite. CONCLUSIONS: The effect of crenulatin on apoptosis of mouse cerebral microvascular endothelial cells possesses a dual - direction change, inhibitive effect in 25 mg/L and stimulative effect in 100 mg/L group, respectively. The mechanism is related to the alterations of Fas/Bcl - 2 expression and caspase - 3 activity.

AIM: To investigate the effect of compound rhubarb preparation (Kintop) in preventing obesity in rats and its probable mechanism involved. METHODS: Twenty-six newborn SD rats were randomly grouped as rhubarb preparation plus high-energy forage group( n= 8), high-energy forage control group( n= 8) and ordinary forage control group( n= 10). The rats in rhubarb preparation plus high-energy forage group and high-energy forage control group were fed with high-energy forage and those in ordinary forage control group were fed with ordinary forage. The rats in rhubarb preparation plus high-energy forage group were administered by compound rhubarb preparation (40 mg?100 g -1 body weight?d -1 ) from 9th to 17th week. The dynamic changes in body weight, celiac fat weight and adipocytes size were measured. Immunohistochemical analysis of leptin in celiac adipocytes (ABC method) and measurement of serum leptin level (RID method) were performed. RESULTS: The body weight and the wet weights of celiac fat were lower, their adipocytes were smaller and immunohistochemical stainings of leptin were weaker in rhubarb preparation plus high-energy forage group than those in high-energy forage control group. There was an obvious positive correlation between the expression of leptin and celiac fat tissue weight( r= 0.8663, P
