Objective: To explore the moderating role of estradiol in the relationship between parenting styles and preschool children's behavioral problems, so as to provide a theoretical basis for improving the development of human s emotional health development in early life stage. Methods: During September to November in 2022, 354 children aged 3-6 years and their parents from two kindergartens in Bengbu City were chosen by using stratified cluster sampling method for the questionnaire survey. The Parenting Style Scale and the Child Behavior Checklist (CBCL) were used to collect information on parenting style and child behavioral problems. Salivary estradiol of children was collected and tested. Independent samples t test was applied to compare the scores of the scale for parental up bringing and children s behavioral problems, and Pearson correlation analysis was conducted to explore the relationship among parental upbringing, estradiol and children s behavioral problems. Results: Parents doting, laissez faire, autocratic, and inconsistent parenting styles were positive associated with child behavior problems( r =0.14-0.70); fathers democratic parenting style was negatively associated with child behavior problems( r =-0.14，-0.22，-0.21，-0.17，-0.27，-0.20); mothers democratic parenting styles was negatively correlated with scores on all five dimensions of child behavior problems except the withdrawal dimension ( r =-0.14，-0.12，-0.13，-0.21，-0.12)( P <0.05). Estradiol levels had significant moderating effects on maternal doting parenting style and children s withdrawal ( β =0.68) as well as social problems ( β =-1.00), also moderating laissez faire parenting styles and children s withdrawal problems ( β =0.75)( P <0.05). For children with low levels of estradiol, withdrawal problem scores were negatively associated with mother s doting parenting style and positively associated with laissez faire parenting style, and socialization problem scores were associated with mother s doting parenting style; for children with high levels of estradiol, withdrawal problem scores were positively associated with mother s doting parenting style, and socialization problem scores were associated with mother s doting parenting style ( t=2.84, 6.24, 3.16 , 2.37, 4.49, P <0.05). Conclusions Parenting styles are strongly associated with child behavioral problems; estradiol levels play a moderating role in mothers doting, laissez faire parenting styles and children s withdrawal problems and social problems.Parents should adopt more positive parenting styles and focus on the role of estradiol levels in maternal education to reduce the occurrence of behavioral problems in children.

Objective To investigate the effects of Tim-3 on the renal ischemia-reperfusion injury (IRI),and explore the role of monocyte-macrophage cell system.Methods Totally 72 C57BL/ 6 mice were randomly divided into four groups (n =18 each).(1) IR + Tim-3 rnAb group (experimental group):Each mouse was intraperitoneally injected with 200μg of anti-Tim-3 mAb and the IR model of mouse kidney was established after 1 day;(2) IR + IgG monoclonal antibody group (negative control group):each mouse was intraperitoneally injected with anti-IgG mAb (200 μg) and the IR model of mouse kidney was established after 1 day;(3) IR group:mouse kidney IR model was established only;(4) Control group:mouse kidney IR model was not established.At 6,24 and 48 h after IR respectively,venous blood of 6 mice in each group was taken from the infrarenal vein.Scr and CystinC were detected and PAS staining was used to observe the pathological change of renal tissues.Cell apoptosis was detected by TUNEL staining.Pax,bcl-2 and caspase-3 expression in renal tissue was detected by Western blotting.Immunohistochemistry was used to detect the distribution of Tim-3 and activated macrophage cells.Flow cytometry and ELISA were used to evaluate the level of Tim-3 and inflammatory cytokines secretion respectively.Results Compared with control group,the Tim-3 expression was dramatically increased in IR group and I/R + Tim-3 mAb group.The serum Scr and CystinC levels were increased in IR group,and Tim-3 blocking decreased the levels of serum Scr and CystinC (P＜0.05).PAS and TUNEL staining showed that renal injury score and apoptotic index were higher in IR group than those in control group.Tim-3mAb significantly decreased those markers,and ameliorated the renal tubulointerstitial injury induced by IRk The expression levels of Caspase-3 and Bax/bcl-2 was increased in IR group,but deceased by Tim-3mAb.IR induced F4/80 + distribution and inflammatory cytokines secretion in renal tubular interstitial tissues,while Tim-3mAb down-regulated F4/80 + activation and the levels of inflammatory cytokines.Conclusion The findings demonstrated Tim-3 may promoted renal IRI through regulating mononuclear phagocyte system function.

Objective: To study the prognostic factors for patients with stage ⅠB non-small cell lung cancer (NSCLC) after radical operation (R0). Methods: The clinical data of 458 patients who underwent radical resection for NSCLC and were pathologically diagnosed with stage ⅠB lung cancer from January 2009 to December 2010, were reviewed retrospectively. Those cases include 269 male patients and 189 female, aged between 28 and 88, with a median age of 61 years. The Kaplan-Meier method and Log rank test were used for univariate survival analysis and the Cox proportional hazards model for multivariate survival analysis. Results: Among these 458 cases, 66 patients were dead and the 5-year survival rate was 85.6%.The results of the univariate analysis showed that the age ≥65 years, elevated preoperative CEA, preoperative FEV1%pred<70%, vascular carcinoma embolus, and low tumor differentiation were associated with poor prognosis of patients(P<0.05). The results of the multivariate analysis showed that elevated preoperative CEA, preoperative FEV1%pred<70% and low tumor differentiation were connected with poor prognosis of patients (P<0.05). Conclusions Elevated preoperative CEA, preoperative FEV1%pred<70% and low tumor differentiation are independent risk factors which influence prognosis and survival rate of patients with stage ⅠB NSCLC, among which those with poorly differentiated tumor could benefit from postoperative chemotherapy.

OBJECTIVETo explore the relationship between the lymph node metastasis and clinicopathological features in patients with clinical stage T1a non-small cell lung cancer (NSCLC).

METHODSClinicopathological data of a total of 418 patients who underwent lobectomy and systematic lymph node dissection were retrospectively analyzed. Logistic regression was used to analyze the relationship between lymph node metastasis and clinicopathological features.

RESULTSLymph node metastasis was observed in 25 patients. There were 122 patients who were diagnosed as ground glass opacity with no lymph node metastasis. 399 patients had subcarinal dissection, among them 7 patients were found to have lymph node metastasis. Univariate analysis showed that gender, smoking history, diameter of lymph node, ground glass opacity (GGO), differentiation of the tumor and tumor site were the factors affecting lymph node metastasis (all P < 0.05). Logistic regression analysis showed that diameter of lymph node, differentiation of the tumor and the site of lesion were independent risk factors for lymph node metastasis of NSCLC.

CONCLUSIONSTumor in the left lung, poor differentiation, and diameter of lymph nodes ≥ 1 cm on the preoperative CT image are independent risk factors for lymph node metastasis of NSCLC, hence we should pay attention before surgery and systematic lymph node dissection should be done. For patients with poor differentiation and lymph nodes ≥ 1 cm, subcarinal lymph nodes dissection is recommended for the sake of higher possibility of lymph node metastasis. For patients with ground glass opacity ≤ 2 cm, the lymph node metastasis is extremely rare, therefore, selective lymph node dissection is reconmmended.

Objective To investigate the effects of a novel PPARγ agonist DH9 on Wntβ-catenin pathway in human polycystic kidney cystic-lining epithelial cells (WT9-12).Methods WT9-12 cells were treated with different concentrations of DH9 for 72 hours and the proliferation was assessed by MTT.WT9-12 cells were pretreated with SB216763 or GW9662 for two hours and then treated with DH9 for 72 hours.Western blotting was applied to detect the protein expression of β-catenin,phospho-β-catenin,GSK3β,phospho-GSK3β.Results DH9 could effectively inhibit the proliferation of the cells.60 μmol/L DH9 could facilitate β-catenin down-regulation (P＜0.01) and phospho-β-catenin up-regulation (P＜0.01).Inhibition of GSK3β by SB216763 could protect WT9-12 cells against DH9-facilitated β-catenin repression in a dose-dependent manner despite phosphorylating deactivation,but PPARγ inhibitor GW9662 couldn't.Conclusions DH9can effectively block the proliferation of WT9-12 cells.The effect may be mediated by facilitating the down-regulation of β-catenin via GSK3β-dependent mechanism.
