Objective To explore the impact of medication self-management module on treatment compli-ance and social function of patients with schizophrenia. Methods 66 inpatients with schizophrenia in their non-acute stage were randomly divided into training group(n=33) and control group(n=33). Both groups received the anti-psychotics therapy. Medication self-management module was only given to the training group for 8 weeks.All subjects were follow up for 6 months and were evaluated with self-made drug treatment compliance rating scale,self-made work ability rating scale, social disability screening schedule(SDSS). Results Treatment compliance,the total scores of SDSS of training group were significantly higher than that of control group after 8 weeks and 6 months: treatment compliance (χ~2=9.188,29.630, P < 0.01); the total scores of SDSS ((2.63±2.74) vs (5.27 ±3.05), (1.69±2.35) vs (4.91±3.06), P=0.000); work ability of training group was significantly higher than that of control group after 6 months (χ~2=19.443, P=0.000). Treatment compliance (χ~2=8.053, P=0. 018), the total scores of SDSS((2.63±2.74) vs (6.81±3.06), P=0.000) of training group after 8 week and 6 months were significantly higher than that of pretraining. Treatment compliance and work ability of both groups on 6 months follow up were significantly lower than that of 8 weeks (P < 0.01). Correlation analysis can-firmed that there was positive relation between the total scores of SDSS and treatment compliance, work ability on 6 months later. Conclusion Medication self-management module could significantly improve treatment compliance,social function and work ability of patients with schizophrenia.

BACKGROUND:There are various commonly used interbody fusion methods, such as autologous bone,
al ograft bone and titanium-based posterior lumbar interbody fusion, and each method has its own advantages and disadvantages.
OBJECTIVE:To observe the clinical efficacy of a bioactive nano-hydroxyapatite/polyamide 66 fusion cage in posterior lumbar interbody fusion for the treatment of lumbar disease.
METHODS:A retrospective case analysis was conducted on 16 cases treated with posterior lumbar interbody
fusion at the Department of Orthopedic, the First Affiliated Hospital of Gannan Medical University from July 2010 to December 2011, and al the patients were implanted with nano-hydroxyapatite/polyamide 66 biological activity fusion cage.
RESULTS AND CONCLUSION:Al the patients were fol owed-up for 10-24 months, and the lumbar pain was significant improved, the lumbar visual analogue score, lumbar Japanese Orthopaedic Association score and Oswestry disability index score were significantly improved during the final fol ow-up period (P<0.05). No internal fixation loosing or broken observed in al the patients during final fol ow-up, and al the patients obtained bone
fusion without nano-hydroxyapatite/polyamide 66 fusion cage displacement or subsidence. The results indicate that nano-hydroxyapatite/polyamide 66 fusion cage for the treatment of posterior lumbar interbody fusion can
reconstruct the lumbar stability and provide immediate stability after implantation, and has good biological activity.

Objective: To observe the incidence of unreasonable use of high beam at nighttime among motor vehicle drivers, so as to provide the evidence for the prevention and control of road traffic injury. Methods: Four roads into city and five urban roads were selected in Yongkang of Zhejiang Province. An automatic recording system was used to collect the unreasonable use of high beam among motor vehicle drivers on the selected roads from 19:00 to 5:00 on Monday, Wednesday, Friday and Sunday during a week in July 2020. The regression tree model was used to analyze the relationship of the unreasonable use of high beam with road, time and traffic flow. Results: A total of 89 989 motor vehicles were observed, and 2 419 motor vehicle drivers had unreasonable use of high beam, with an incidence rate of 2.69%. The incidence rate of the unreasonable use of high beam was 3.14% in the roads into city, which was higher than 2.30% in the urban roads ( P<0.05 ). The incidence rates of the unreasonable use of high beam in the roads into city and in the urban roads were 5.15% and 2.90% on Wednesday, which were higher than those on Monday ( 2.89% and 2.34% ), Friday ( 2.90% and 1.92% ) and Sunday (2.06% and 2.12%). The highest incidence rate of the unreasonable use of high beam in the roads into city was 6.07% between 4:00 and 5:00, and in the urban roads was 4.50% between 2:00 and 3:00. The results of regression tree classification analysis showed that the highest incidence rate was 8.13% on the roads into city in the east, west and south directions, and on the urban roads in the east and north directions with less than 317 vehicles per hour on Wednesday. Conclusion It is more likely for motor vehicle drivers to use high beams unreasonably at nighttime on the roads into city with less traffic flow.

Objective To prepare the acellular carotid artery of adult pig using biotic enzymes for small-diameter vascular tissue-engineering scaffold.Methods Carotid artery of adult pig was removed cells by using Trypsin/EDTA,ribonuclease and desoxyribonuclease.Residual cellular composition was studied with quantitative DNA analysis and the Hematoxylin and Eosin(H&E)staining.Extracellular matrix composition was evaluated with elastin van Gieson's(VG)staining and scanning electron microscopy(SEM).Results Quantitative DNA analysis and H&E staining confirmed that carotid arteries were completely decellularized.Elastin van Gieson's staining demonstrated that elastin morphology appeared unchanged.Scanning electron microscopy examination of the acellular scaffolds revealed a well-oriented porous decellularized structure that maintained natural architecture of the aorta.Conclusion Carotid artery of adult pig rendered acellular with Trypsin/EDTA,ribonuclease and desoxyribonuclease has well-preserved extracellular matrix for vascular scaffold,which can be used as a scaffold for further small-diameter vascular tissue engineering.

Objective:To explore the clinical effects of penile ventral Z-shaped cross flap and penile dorsal pedicled transfer flap in penoplasty for concealed penis.Methods:From January 2017 to June 2019, the data of 151 patients with concealed penis admitted to our hospital was retrospectively reviewed. The patients were divided into 2 groups according to the surgical method. 69 cases were treated with penis ventral Z-shaped cross flap to form penis and 82 cases were treated with dorsal penis pedicled flaps to form the penis. In Z-shaped flap group, the penis length of 33 patients with tight scrotum was (3.06±0.25)cm before surgery and the penis length of 36 patients with relaxed scrotum was (2.99±0.28) cm before surgery. In flap with transfer group, the penis length of 39 patients with tight scrotum was (3.04±0.30)cm before surgery and the penis of 43 patients with relaxed scrotum was (3.04±0.24)cm before surgery. The length of the penis after surgery and incidence of postoperative complications were compared between Z-shaped flap group and flap with transfer group. Common complications included penile body retraction, foreskin edema, foreskin stenosis and penile wound splitting.Results:151 patients were followed up for 6-12 months, and all patients were satisfied with penis appearance. There was no penile necrosis or urinary fistula. In Z-shaped flap cross group, the penis length of 33 patients with tight scrotum extended (2.47±0.22)cm after surgery.The penis length of 36 patients with scrotum relaxation extended (2.61±0.27)cm after surgery, 39 patients was adopted the penile dorsal pedicled transfer flap with scrotum tight had extended penis (2.90± 0.16)cm, which significantly different from the Z-shaped flap group( P<0.05). In flap with transfer group, 43 patients with relaxed scrotum extended (2.79±0.18)cm after surgery, which was significantly different from the Z-shaped flap group ( P<0.05). In Z-shaped flap group, 33 patients with scrotum tight, there were 2 cases of penile retraction, 1 case of stenosis of the foreskin, 2 cases of foreskin edema, 2 cases of penile wound rupture. In transfer flap group, of 39 patients with scrotum tight, there was 1 case of foreskin edema. The incidence of complications that adopted the penile dorsal pedicled transfer flap with scrotum tight was lower than those adopted penile ventral Z-shaped cross flap [2.56%(1/39) vs. 21.21%(7/33), P=0.033]. In transfer flap group, of the 43 patients with scrotum relaxation, there were 3 cases of penile retraction, 3 cases of foreskin stenosis, 2 cases of penile ventral foreskin edema, and 1 case of penile wound rupture. Z-shaped flap group: 36 patients was scrotum relaxation was 1 case of foreskin edema. The incidence of complications that adopted the penile dorsal pedicled transfer flap was higer than those adopted penile ventral Z-shaped flap [20.93%(9/43) vs. 2.78%(1/36), P =0.038]. Conclusions:In terms of children with tight scrotum or loose scrotum, the effect of the transfer flap method to extend the penis is better than that of the Z-shaped flap method. However, the transfer flap method has a low complication rate for children with tight scrotum, while the Z-shaped flap method has a low complication rate for children with loose scrotum.

Objective To evaluate the effect of chidamide combined with matrine on proliferation and apoptosis of cutaneous T-cell lymphoma (CTCL) cell lines HH and Hut78,and to explore their apoptotic mechanisms.Methods Both HH and Hut78 cells were treated with 0.4 μmol/L chidamide and 0.6 g/L matrine alone or in combination for 24,48 and 72 hours,with those treated with dimethyl sulfoxide (DMSO) serving as control groups.MTS assay was performed to deteet cellular proliferation rates of HH and Hut78 cells at each time point.After 48-hour treatment,flow cytometry was conducted to detect cell apoptosis,and Western blot analysis to determine expression of apoptosis-related proteins in these cells.Statistical analysis was carried out by using repeated measures analysis of variance,one-way analysis of variance,and least significant difference (LSD)-t test for multiple comparisons.Results Compared with DMSO,chidamide and matrine alone or in combination could inhibit the proliferation of HH and Hut78cells to different extents (F =15.88,558.26,P ＜ 0.05,＜ 0.001,respectively).At 48 hours,the apoptosis rate in Hut78 cells was significantly higher in the matrine group (20.98％ ± 1.53％),chidamide group (22.44％ ± 7.74％) and combination group (44.53％ ± 1.85％) than in the control group (8.42％ ± 4.23％;LSD-t =4.76,5.31,13.69 respectively,all P ＜ 0.05),as well as in the combination group than in the matrine group and chidamide group (LSD-t =8.93,8.37 respectively,both P ＜ 0.01);no significant differences were observed in the apoptosis rate of HH cells between the matrine group (13.98％ ± 3.86％)or chidamide group (13.61％ ± 1.62％) and control group (11.44％ ± 1.43％,both P ＞ 0.05),while the combination group (20.94％ ± 0.64％) showed a significantly higher apoptosis rate compared with the control group,matrine group and chidamide group (LSD-t =7.37,5.40,5.69 respectively,all P ＜ 0.05).In the case of HH cells,the combination group showed significantly higher cleaved caspase-3 expression (all P ＜ 0.05),but significantly lower protein expression of E-cadherin,nuclear factor (NF)-κB,phosphorylated-Bad (p-Bad) and Bcl-2 compared with the other 3 groups (all P ＜ 0.05).In the case of Hut78 cells,the expression of E-cadherin,NF-κB,p-Bad and Bcl-2 was significantly lower in the matrine group,chidamide group and combination group than in the control group (all P ＜ 0.05),while cleaved caspase-3 expression was significantly higher in the chidamide group and combination group than in the control group (both P ＜0.05).No matter in HH cells or in Hut78 cells,there were no significant differences in Bad protein expression between the 4 groups (all P ＞ 0.05).Conclusion Chidamide in combination with matrine can inhibit proliferation and induce apoptosis of HH and Hut78 cells,likely by regulating the expression of apoptosis-related proteins E-cadherin,NF-κB,p-Bad,Bcl-2 and cleaved caspase-3.

Objective:To evaluate the safety and clinical effect of holmium laser enucleation of the prostate (HoLEP) for pati-ents with benign prostatic hyperplasia (BPH) .Methods:A total of 40 patients with BPH from Jan 2015 to Jul 2015 were underwent HoLEP.Pre-and postoperative complication were recorded and the differences of the clinical parameters were also compared, including peak urinary flow rate (Qmax), residual urine volume (PVR), International Prostate Symptom Score (IPSS), quality-of-life (QOL) .Results:A total of 34 patients were included after operation and 6 patients lost to follow-up. Qmax, PVR, IPSS, QOL after three months postoperatively were improved significantly compared with that of preoperative (P<0.01) .Complications included intraoperative bladder injury (1 case), postoperative stress incontinence (2 cases), urethral stricture (1 case) .No patients experienced the sign of TUR syndrome and blood transfusion for severe bleeding.Conclusion:HoLEP has the advantage of good therapeutic effects,wide scope of application,better safety performance,smaller risk and it’s worth popularizing in primary hospitals.

Objective: To determine the association between the intake of five major types of prepackaged foods and the growth and development of school aged children, so as to provide a theoretical basis for guiding school aged children and their parents to make healthy prepackaged food choices. Methods: Based on data from the South West China Childhood Nutrition and Growth Cohort (SCCNG), 381 children (6-11 years of age) were selected by stratified cluster sampling. Dietary intake and pubertal development were collected using questionnaires, and anthropometric measurements were obtained. Children were followed up until November 2022. Binary Logistic regression models were used to analyze the prospective association between prepackaged food intake and the growth and development of school aged children. Results: The total intake of the five major types of prepackaged foods was 316.1 (197.1,501.4) g/d. After 2 years of follow up evaluations, 16.5% of school aged children were shown to be overweight and obese. Early spermarche occurred in 12.6% of boys and early menarche occurred in 15.4% of girls. The following findings were suggested after adjusting for the mothers education level, average gross monthly family income, whether or not the family had one child only, geographic area of residence, body mass index Z score, average duration of daily exercise, and total dietary energy intake: convenience food intake might increase the risk of early spermarche ( OR =9.37); fruit and vegetable intake might decrease the risk of early spermarche and menarche ( OR =0.33,0.17); and fish, poultry, meat, and egg intake might increase the risk of early menarche ( OR =7.59)( P <0.05). Intake of the five types of prepackaged foods was not associated with being overweight or obese after adjusting for confounders ( OR =1.40, 0.57, 0.73, 1.33,1.57, P >0.05). Conclusions The relationship between intake of the five major types of prepackaged foods and pubertal development is inconsistent and no significant correlation was detected between the intake of prepackaged foods and overweight or obese children. Nutrition education should be strengthened to help children and their parents choose healthy prepackaged foods.
