Objective To investigate the effects of rottlerin on in vitro proliferation of and expressions of interleukin (IL)-17C,CCL20 chemokine,and nuclear factor (NF)-κB in cultured human HaCaT keratinocytes.Methods Some HaCaT cells were divided into several test groups treated with rottlerin at concentrations of 0.5,1.0,2.0 and 4.0 μmol/L,a solvent group treated with RPMI 1640 culture solution containing the same volume of dimethyl sulfoxide (DMSO) as that of 4.0 μmol/L rottlerin,and a control group treated with RPMI 1640 culture solution.Cell counting kit-8 (CCK8) assay was conducted to estimate the proliferative activity of HaCaT cells after 24-,48-and 72-hour culture,RT-PCR to determine the mRNA expressions of IL-17C and CCL20 after 48-hour culture,and Western blot to measure the protein expressions of IL-17C,CCL20 and NF-κB after 48-hour culture.Statistical analysis was carried out by using repeated-measures analysis of variance,one-way analysis of variance and Pearson correlation analysis with the SPSS16.0 software.Results Rottlerin showed an inhibitory effect on the proliferation of HaCaT cells,and the inhibitory effect increased over time (F =126.936,P ＜ 0.05) and with the increase of rottlerin concentrations (F =838.308,P ＜ 0.05),with a significant interaction effect between rottlerin concentrations and treatment duration (F =15.961,P ＜ 0.05).After 48-hour treatment,a significant decrease was observed in the mRNA and protein expressions of IL-17C (F =206.041,233.887,respectively,both P ＜ 0.05) and CCL20 (F =143.883,162.431,respectively,both P ＜ 0.05),as well as in the protein expression of NF-κB (F =577.915,P ＜ 0.05) in the test groups with the increase in rottlerin concentrations.Conclusions Rottlerin can inhibit the proliferation of HaCaT cells in vitro,and decrease the mRNA and protein expressions of IL-17C and CCL20 likely by downregulating the protein expression of NF-κB.

Objective To describe the prevalence of smoking and smoking cessation in adults of Jiangxi province in 2013.Methods Multi-stage stratified cluster random sampling method was used to select 6 000 individuals aged ≥18 years from 10 chronic and non-communicable disease and risk factor surveillance points of Jiangxi province in 2013.A face-to-face questionnaire survey was carried out to collect information about the risk factors for chronic and non-communicable diseases and 5 997 records were used in final analysis of smoking and smoking cessation.Sample was weighted to represent the adult population of Jiangxi province.The prevalence of different groups were analyzed.Results The prevalence of current smoking of the sample was 21.53％ (1 291/5 997).After complex weighting,the prevalence of smoking was 26.07％ in adults in Jiangxi (95％ CI:23.48％-28.66％),and it was much higher in men (50.62％,95％CI:46.31％-54.94％) than in women (1.46％,95％CI:0.57％-2.35％),the difference was statistically significant (P＜0.05).The differences in smoking prevalence were significant among different age groups (P=0.029),and the smoking prevalence increased with educational level,but decreased with the worse of self-reported health condition.Most current smokers smoked every day (87.16％,95％CI:83.29％-91.03％) and averagely 19.27 (95％ CI:17.69-20.85) cigarettes were smoked daily.The proportion of smokers with average daily consumption ≥20 cigarettes was 64.74％ (95％CI:55.79％-73.70％).The smokers' average age of starting daily smoking was 20.28 (95％CI:19.74-20.82) years old,which was lower in men [20.11 (95％ CI:19.61-20.61) years old] than in women [26.88(95％ CI:24.73-29.03) years old],the difference was statistically significant (P＜0.05).Among the male smokers,27.04％ (95％ CI:18.91％-35.16％) of male smokers was less than 18 years old when they started daily smoking,and the proportion was 17.46％ (95％ CI:0％-37.71％) in female smokers.The smoking cessation rate was 14.80％ (95％CI:10.88％-18.72％) and increased with age,the increase of income level and the worse of self-reported health condition.The successful smoking cessation rate was 10.89％ (95％ CI:8.36％-13.42％).Only 32.10％(95％CI:21.95％-42.25％) of current smokers attempted to quit smoking.The prevalence of passive smoking was 54.71％ (95％ CI:44.20％-65.21％).Conclusion The prevalence of smoking was high in adults in Jiangxi and the proportion of heavy smokers was large.Less smokers quitted smoking and the proportion of current smokers attempting to quit smoking was small.Males and adolescent smokers are targeted populations for tobacco control and special strategy should be taken according to the characteristics of smoking population in Jiangxi.

Objective To investigate the therapeutic effect of Qiwei Zhigan prescription on two classic animal models of non-alcoholic steatohepatitis(NASH).Methods Methionine-choline-deficient(MCD)rat model and choline-deficient,L-amino acid-defined,high-fat and high cholesterol diet(CDAHFHC)mouse model were used.48 rats and 96 mice were randomly divided into 6 groups:control group,model group,Qiwei Zhigan prescription group(low,medium and high dose group),positive drug group.After 2 weeks of modeling,the drugs were administrated continuously for 28 days.The efficacy of Qiwei Zhigan prescription in the treatment of non-alcoholic steatohepatitis was evaluated by detecting the serum liver function,blood lipid biochemical index and liver tissue lipid levels of each group of animals,as well as by evaluating the liver histopathological changes.Results The gross anatomical morphology of the liver was improved by Qiwei Zhigan after oral administration of clinical equivalent dose or higher doses in two experimental animal models.The liver weight and liver index of NASH mice were reduced by the prescription.The levels of ALT,ALP and LDH in serum of NASH rats were decreased,and the level of HDL was increased.The levels of ALT,AST,TBIL,ALP,LDH and TG in serum of NASH mice were decreased,and the content of TG in liver was also decreased.The pathological damage of liver tissue was ameliorated,the inflammation of liver tissue was reduced,as well as the degree of ballooning of liver cells and the NAS score of the liver,and there was a certain dose-effect relationship between the groups;the proliferation of collagen fibers in the hepatic lobules and around the portal area of NASH mice was significantly reduced;the density of positive cells labeled by F4/80 was decreased,and the activation of Kupffer cells was alleviated.Conclusion Qiwei Zhigan prescription could effectively ameliorate the progression of two classic NASH models,and decrease the development trend from liver inflammation to liver fibrosis in NASH.

The BUB1 mitotic checkpoint serine/threonine kinase B(BUB1B)maintains a high fidelity of mitotic chromosome segregation by preventing the initiation of anaphase without the attachment of one or more kinetochore to the spindle,and plays a major role in both signal transduction and the stable attachment of kinetochore to micro-tubules.The dysregulated expression of BUB1B may affect the occurrence of mitosis-induced aneuploidy,chromo-some instability and abnormal cell biological function,leading to cell malignant transformation.This review summa-rizes the role of BUB1B in the occurrence and development of gynecological malignant tumors.

Diabetic foot refers to lower limb infection, ulceration and/or deep tissue destruction caused by complicated neuropathy and various degrees of lower extremity vascular disease in patients with diabetic foot. Diabetic foot is one of the main chronic complications of diabetes, which is characterized by long course of disease, difficulty to cure, high psychological burden, high economic burden, high disability rate and high mortality rate and therefore poses a severe threat to the quality of life and prognosis of patients with diabetes. Silver-containing dressings are a new type of wound antibacterial dressing that has been successfully used in the treatment of a variety of wounds. This article tries to review the progress of the application of silver ion dressings in the treatment of diabetic foot.

Objective:To investigate the relationship among mental health,maternal negative emotion and mother-child attachment in preschoolers.Methods:A total of 591 mothers of preschoolers from 8 kindergartens were selected.The Preschoolers Mental Health Scale(PMHS)was used to evaluate mental health of the preschool-ers,the Self-rating Depression Scale(SDS)and Self-rating Anxiety Scale(SAS)were used to evaluate maternal negative emotions,and Maternal Object Relationship Scale-Short Form(MORS)was used to evaluate mother-child attachment.Results:The scores of SDS and SAS were positively correlated with the total scoresand scores of each dimension of PMHS(r=0.69-0.93,Ps＜0.001).The maternal SDS and SAS scores were positively associated with total PMHS scores(β=0.38,0.52).The products of maternal SAS scores and MORS scores were negatively associated with the total PMHS scores(β=-0.12).Conclusion:Preschoolers mental health is closely related to a maternal negative emotion and mother-child attachment.

Objective: To study the factors affecting the survival and prognosis of patients with intracranial ependymoma. Methods:From January 2008 to January 2018, the prognoses of 276 patients with intracranial ependymoma were analyzed using Log-rank and Cox model analysis. The variables included sex, age, tumor location, tumor diameter, resection extent, pathological grade, Ki-67 index, postoperative radiotherapy, and postoperative chemotherapy. Results: Tumor location, resection extent, and postoperative radiothera-py could all affect the overall survival (OS) and progression-free survival (PFS) of patients with intracranial ependymoma (P<0.001) and independently affected the OS (P<0.001, P<0.001, and P=0.002, respectively) and PFS (P<0.001, P<0.001, and P=0.001, respectively). The Ki-67 index was an independent factor affecting PFS in patients with intracranial ependymoma (P<0.001). The supratentorial loca-tion and Ki-67 index≥10% were independent risk factors indicating poor prognosis (P<0.001). Total resection and postoperative radio-therapy were protective factors (P<0.001 and P=0.001, respectively). Conclusions: Tumor location, resection extent, Ki-67 index, and postoperative radiotherapy are independent factors affecting the prognosis of intracranial ependymoma. It is helpful to extend the PFS and OS of patients through complete tumor resection or postoperative radiotherapy.

Objective To analyze the effect of ultrasound-guided glucocorticoid injection on different pathologies of the shoulder retrospectively.Methods Clinical data were collected describing 75 patients with shoulder pain who received ultrasound-guided glucocorticoid injection and finished 3 month follow-ups in the rehabilitation clinic of the Third Affiliated Hospital of Sun Yat-sen University between April and September of 2017.The patients were divided into three groups based on their different injection sites:group 1 was injected at the subacromial bursa alone,group 2 was injected at both the subacromial bursa and the coracoid bursa,while group 3 was injected at the subacromial bursa and the long head of the tendon sheath of the biceps brachii.A shoulder pain and disability index (SPADI) was used to quantify the pain and disability of each patient before and after the injection.Results Significant improvement was observed in the average pain and disability scores of all groups at 1 week,1 month and 3 months after the injection.Moreover,significant and continuous improvement was observed in the average pain and disability scores of groups 1 and 3,as well as the average disability score of group 2 from right after the injection until the last follow-up.However,no significant differences were found in the average pain score between one and three months after the injection.There was no significant difference among the 3 groups in the average pain and disability scores before and immediately after the injection.Conclusion Ultrasound-guided glucocorticoid injection is effective and persistent for treating shoulder pain with different pathologies.

Objective To explore the effect of jogging on the patients with depression disorder of liver-stagnation and spleen-deficiency.Methods 100 patients with liver-stagnation and spleen-deficiency depression disorder were randomly selected from Tongde Hospital of Zhejiang Province from March to September 2022.They were divided into observation group and control group(50 cases each)by random number table method.The control group received conventional antidepressant drug treatment,and the observation group was given jogging exercise regimen on the basis of the control group:exercise at least 4 times a week,30-60 min each time,and the heart rate was maintained at 110-120 times/min for 4 weeks.The depressive disorder of the patients was assessed by Zung's Self-rating Depression Scale(SDS)and 17-item Hamilton Depression Scale(HAMD-17).Results After jogging exercise intervention,the total effective rate of the observation group was 94%,which was significantly higher than that of the control group 80%(P<0.05).HAMD-17 score was significantly lower in the observation group than in the control group after intervention(F=12.575,P<0.05).The scores of cognitive impairment,block and sleep disturbance in the observation group were significantly lower than those in the control group after intervention(F=12.575,P<0.05).The body weight factor scores of the observation group and the control group were significantly higher after intervention than before intervention(P>0.05).Conclusions Jogging exercise intervention therapy can significantly improve the depression of patients with liver-qi and spleen-deficiency depression disorder,and jogging can be an effective method to prevent and treat depression disorder.

Objective:To explore the correlation between frailty and foot care behavior in elderly patients with high-risk diabetic foot.Methods:From January to June 2022, 220 patients with high-risk diabetic foot who were admitted to the Department of Endocrinology and Department of Geriatrics of Xuanwu Hospital of Capital Medical University were selected by convenience sampling as the research object. The patients were investigated with the General Information Questionnaire, Gavin's Weighted Scale for Diabetic Foot Risk Factors for Progression to Ulceration, the Chinese version of the Frail Scale and the Foot Care Behavior Questionnaire for Diabetic Patients. Spearman correlation analysis was used to explore the correlation between frailty and foot care behavior in elderly patients with high-risk diabetic foot. Multiple linear regression was used to analyze the influencing factors of foot care behavior in elderly patients with high-risk diabetic foot. A total of 220 questionnaires were distributed, and 210 valid questionnaires were collected, with an effective response rate of 95.45% (210/220) .Results:The standardized score of the Foot Care Behavior Questionnaire for Diabetic Patients among 210 elderly patients with high-risk diabetic foot was (56.65±11.27), which was in the middle to low level. Among them, 126 patients (60.00%) were at a low level, and 80 patients (38.10%) were at a middle level. The incidence of frailty in 210 elderly patients with high-risk diabetic foot was 27.14% (57/210). The results of correlation analysis showed that the frailty score of elderly patients with high-risk diabetic foot were negatively correlated with the scores of the foot and footwear examination, foot cleaning and maintenance, footwear selection, and the total score of Foot Care Behavior Questionnaire for Diabetic Patients ( P<0.05). The results of multiple linear regression analysis showed that gender, frailty, foot risk classification and living conditions were the influencing factors of foot care behavior in elderly patients with high-risk diabetic foot ( P<0.05) . Conclusions:The foot care behavior of elderly patients with high-risk diabetic foot needs to be improved. The higher the degree of frailty, the lower the level of foot care behavior. Medical and nursing staff should formulate targeted intervention measures according to the characteristics of patients to improve or delay the progression of patients' frailty, thereby improving their foot care behavior and preventing the occurrence of diabetic foot.
