Objective To explore the application effect of high-functioning group therapy model in female patients with depression.Methods A total of 80 female patients with depression who were hospitalized in the Department of Psychiatry,the Second Affiliated Hospital of Xinxiang Medical University from April 2021 to April 2022 were selected as the research sub-jects.According to the treatment methods,the patients were divided into the observation group and the control group,with 40 patients in each group.The patients in the two groups were treated with routine anti-depressant drugs based on their condition;the patients in the control group received routine nursing interventions based on their condition;the patients in the observation group received high-function group therapy intervention on the basis of the control group;the patients in the two groups were in-tervened for 1 month.Before and one month after the intervention,the levels of depression and anxiety of patients in the two groups were evaluated by the Hamilton depression scale(HAMD)and the Hamilton anxiety scale(HAMA);the quality of life of patients in the two groups was evaluated by the World Health Organization's quality of life scale(WHOQOL-BREF),while the interpersonal relationships of patients in the two groups were evaluated by the interpersonal relationships comprehensive diagnostic scale.Results Before intervention,there was no statistically significant difference in the scores of HAMA,HAMD,WHOQOL-BREF and interpersonal relationship comprehensive diagnostic scale of patients between the two groups(P＞0.05).The HAMA and HAMD scores of patients in the two groups after one month of intervention were significantly lower than those before intervention(P＜0.05);after one month of intervention,the HAMA and HAMD scores of patients in the observa-tion group were significantly lower than those in the control group(P＜0.05).The WHOQOL-BREF scores in the social,psychological,physiological and environmental domains of patients after one month of intervention were significantly higher than those before intervention in the two groups(P＜0.05);after one month of intervention,the WHOQOL-BREF scores in the social,psychological,physiological and environmental domains of patients in the observation group were significantly higher than those in the control group(P＜0.05).The scores of interpersonal interaction,conversation,social interaction and hetero-sexual interaction and total scores of interpersonal relationship comprehensive diagnosis scale of patients one month of interven-tion were significantly lower than those before intervention in the two groups after(P＜0.05);after one month of intervention,the scores of interpersonal interaction,conversation,social interaction and heterosexual interaction and total scores of interper-sonal relationship comprehensive diagnosis scale of patients in the observation group were significantly lower than those in the control group(P＜0.05).Conclusion Compared to conventional nursing interventions,the high-functioning group therapy model can significantly reduce the depression and anxiety of female depression patients,improve interpersonal communication skills and their quality of life.

Abstract OBJECTIVE To explore the effect of the polymorphisms of ATM(rs11212617), KCNJ11(rs5219), CYP2C9(rs1799853, rs1057910), TCF7L2(rs12255372, rs290487) and IRS1(rs1801278) on efficacy of metformin and gliclazide combined treatment for diabetes mellitus type 2. METHODS Eighty-one patients with newly diagnosed diabetes mellitus type 2 in Standardized Metabolic Disease Management Center of the Endocrinology Department of of Zhejiang Chinese Medical University Affiliated Jiaxing TCM Hospital were enrolled in this study, and they were treated with metformin hydrochloride tablets and gliclazide modified release tablets. MassARRAY was used to type the above single nucleotide polymorphism(SNP), and followed up for 3 months. Fasting plasma glucose(FPG), glycosylated hemoglobin type Alc(HbA1c) and fasting insulin(FINS) were compared before and after treatment. RESULTS The gene frequencies of all SNPs were compliant to Hardy-Weinberg equilibrium, the samples were well represented. The rs1799853, rs1057910, rs12255372 and rs1801278 had low mutation frequencies with poor clinical significance. The benefits of FPG compliance rate, increase of FINS, decrease of HbAlc after treatment were stronger in patients with homozygous rs5219 C allele than those with T-allele carriers (P<0.05). However, there were no significant differences in treatment effects among the genotypes of rs11212617 and rs290487. CONCLUSION The rs5219 polymorphism of KCNJ11 gene is associated with the efficacy of metformin hydrochloride tablets and gliclazide modified release tablets in treating diabetes mellitus type 2, with a more significant effect observed in individuals homozygous for the C allele. This finding can serve as a reference for personalized medication in clinical treatment of diabetes mellitus type 2.

Objective To investigate the significance of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in serum and cerebrospinal fluid for evaluation of severe hand ,foot ,and mouth disease (HFMD) complicated with neurogenic pulmonary edema (NPE).Methods A total of 140 patients diagnosed with HFMD in Henan Children′s Hospital were enrolled and divided into three groups including mild group ,severe HFMD group without NPE ,severe HFMD group with NPE .These severe HFMD patients were also divided into survival group and death group according to the 28-day prognosis .Meanwhile ,50 age-matched healthy children were selected as controls .Serum MMP-9 and TIMP-1 levels were measured in all enrolled children .At the same time ,MMP-9 ,TIMP-1 and ratio of MMP-9／TIMP-1 in cerebrospinal fluid were measured in the severe HFMD group with and without NPE .Quantitative data were compared using one-way analysis of variance , and means comparisons between samples were conducted using LSD-t test .Results Among 140 children with HFMD ,66 were in mild group ,42 in severe HFMD without NPE group ,and 32 in severe HFMD with NPE group .And 50 healthy children were in control group .After 28 days ,14 cases died in severe HFMD groups .MMP-9 , TIMP-1 and MMP-9／TIMP-1 in serum of severe HFMD group with NPE increased significantly greater than those in the other three groups (F＝269 .356 ,121 .301 and 101 .502 ,respectively ,all P ＜0 .05). MMP-9 ,TIMP-1 and MMP-9／TIMP-1 in cerebrospinal fluid of severe HFMD group with NPE were (57 .24 ± 8 .92) μg／L ,(35 .26 ± 8 .14) μg／L and (1 .66 ± 0 .23) μg／L ,respectively ,while those in cerebrospinal fluid of severe HFMD group without NPE were (30 .57 ± 3 .89) μg／L ,(26 .25 ± 0 .32) μg／L and (1 .17 ± 0 .61) μg／L ,respectively .The differences between the two groups were all statistically significant (t＝62 .485 ,37 .680 and 169 .387 ,respectively ,all P＜0 .01).MMP-9 ,TIMP-1 and MMP-9／TIMP-1 in serum and cerebrospinal fluid of death group increased significantly greater than those in survival group ,the difference were statistically significant (all P＜0 .01).The maximum area under curve (AUC) was reached when the MMP9／TIMP-1 ratio in cerebrospinal fluid was 0 .890 (95% CI :0 .801 －0 .978).Conclusions MMP-9 and TIMP-1 may be involved in the pathogenesis of HFMD complicated with NPE .The detection of MMP-9 and TIMP-1 levels may be beneficial for the early diagnosis of severe HFMD with NPE .The imbalance of MMP-9／TIMP-1 ratio can be used as one of the predictors of severe HFMD combined with NPE.

Objective To estimate cervical stiffness during late pregnancy with virtual touch tissue quantification technique(VTQ) and investigate the value of predicting the outcome of labor induction. Methods Cervical length in pregnancy women at 35 -41 weeks′gestation was measured through perineum ultrasound examination before labor induction,and then VTQ was applied to measure shear wave velocity (SWV)values in region of interest(ROI),the maximum,minimum and average of SWV values were obtained from multiple SWV measurement under the VTQ mode. The outcomes of labor induction were tracked and Bishop scores were recorded,vaginal delivery and cesarean delivery groups were compared using Student′s t-test for continuous variables. ROC curve was plotted to analyze the correlation between parameters and the outcome of labor induction and to determine the most accurate SWV value and cut-off value for diagnosis.Univariate and multivariate logistic regression analysis were used to determine which of the following parameters were significant predictors of the outcome of labor induction. Results The SWV mix,SWV max and SWV mean of vaginal delivery and cesarean section were (0.92 ± 0.13)m/s,(1.37 ± 0.14)m/s,(1.13 ± 0.10)m/s and (1.03 ± 0.13)m/s,(1.74 ± 0.42)m/s,(1.36 ± 0.11)m/s,respectively, there were significant differences between vaginal delivery and cesarean section(all P < 0.05).Based on ROC curve analysis,the SWV mean value in cervix was the best value for predicting the outcome of labor induction.The cut-off value of SWV mean value was 1.23 m/s,the sensitivity,specificity and Youden index were 93.8%,83.4%,0.77,respectively.The SWV value and cervical length were closely correlated to the outcome of labor induction,especially the SWV value according to multivariate logistic analysis. Conclusions VTQ can assess the cervical stiffness with SWV values during pregnancy,and it may have an application value of predicting the outcome of labor induction.

OBJECTIVETo investigate the expression of SFRP4 and DKK1 in cervical squamous cell carcinoma and explore the clinicopathological implications.

METHODSImmunohistochemistry and reverse transcriptase-polymerase chain reaction (RT-PCR) were used to detect the expressions of SFRP4 and DKK1 in 66 cervical squamous cell carcinoma and 26 normal cervical specimens.

RESULTSSFRP4 expression was significantly higher (P<0.01) and DKK1 expression was significantly lower (P<0.05) in the carcinoma tissues than in normal cervical tissues. DKK1 was negatively correlated with SFRP4 in the carcinoma tissues (P<0.01), and their expressions were associated with the clinical stages, tumor differentiation, depth of invasion and lymph node metastasis of the tumors (P<0.05).

CONCLUSIONSFRP4 and DKK1, the upstream components of the Wnt pathway, play a key role in the tumorigenesis of cervical squamous cell carcinoma, and their expressions are associated with the clinicopathological features of the malignancy.
