Both levels of serum leptin and BMI were significantly higher in T2DM patients with severe NAFL (n=61) than those in T2DM with mild NAFL (n=24), T2DM without NAFL (n=45) and in normal control (n=30).

The ptrpose of this study was to investigate the effects of long-term estradiol and progesterone combined therapy on bone mineral density (BMD) in patients with Turner syndrome.Eight patients with Turner syndrome received estradiol and progesterone combined therapy for six years were observed and BMD was measured for each of them before hormone replacement therapy (HRT) and at an interval of one to two years after HRT and compared with that in normal age-sex matched women.BMD was significantly lower in patients with Turner syndrome than that in normal controls before HRT.All the patients with Turner syndrome had breast enlargement and irregular vaginal bleeding after HRT.BMD increased slightly in the patients with Turner syndrome after six-year HRT ,but still much lower than that in normal controls.Their BMD of the 2nd to 4th lumbar vertebra increased to (0.84±0.22) g/cm2 after HRT from (0.75±0.12)g/cm2 before it,with Z-score increased to -2.2±0.6 from -3.2±0.9,respectively; and overall BMD of the hip increased to (0.81±0.08) g/cm2 after HRT from (0.68±0.07) g/cm2 before it,with Z-score increased to-1.2 ± 0.3 from-2.2 ± 0.5,respectively.Long-term HRT can improve their BMD for patients with Turner syndrome but can not restore it to normal.

Objective: To learn the characteristics of injury cases caused by animals in Wenzhou and to provide the reference for injury prevention. Methods: We collected the data of injury cases caused by animals in six sentinel hospitals in Wenzhou from 2016 to 2018,and analyzed the animal species,the severity and the location of injury. We conducted circular distribution method for the seasonal distribution features of injury cases. Results: There were 3 743 cases caused by animals in Wenzhou from 2016 to 2018,with 2 045（54.64%）males and 1 698（45.36%）females. About 43.68%（1 635）of cases were 15-44 years old. About 31.66%（1 185）of cases were students and preschool children. There were 2 445 cases（65.32%）caused by dog and 3 212 cases（85.81%）occurred at home. The results of circular distribution analysis showed that the third quarter of a year was the peak time of injuries caused by animals（Z=251.32,P<0.05）,with 1 342 cases accounting for 35.85%. Conclusion Most injury cases in Wenzhou caused by animals are caused by dogs and occur at home in summer,affecting children and young adults.

Objective: To investigate the inhibition of tanshinoneⅡA (TanⅡA) on the proliferation of lung cancer cells. Methods: Human lung cancer cell lines A549, SK-MES-1, H446 and H460 were cultured in vitro and treated with TanⅡA at concentrations of 0.3, 0.6, 1.3, 2.5, 5.0, 10.0 mg/mL, while untreated cells served as controls. Cell proliferation was measured by using CCK-8 assay, and apoptosis was measured using flow cytometry, while the expression of apoptosis-related proteins was determined using Western blotting. The apoptotic rate of lung cancer cells was compared between Tan ⅡA-treated cells and untreated cells. Results: Tan ⅡA inhibited lung cancer cell proliferation in a time-dependent and concentration-dependent manner, and the survival rates of A549, SK-MS-1, H446 and H460 cells reduced with the concentration of TanⅡA (t=4.503, 2.114, 2.103 and 3.567; all P<0.05) and the duration of TanⅡA treatment (t=5.189, 3.079, 3.023 and 3.845; all P<0.05). The 48 h half maximal inhibitory concentrations (IC50 values) of TanⅡA were (1.18±0.12), (0.78±0.08), (1.55±0.16) and (1.27±0.14) mg/mL against A549, SK-MES-1, H446 and H460 cells, respectively. Following 48 h treatment with Tan ⅡA at a concentration of 2.5 mg/mL, the apoptotic rates of A549, SK-MS-1, H446 and H460 cells were (34.97±3.78)%, (37.62±2.48)%, (18.27±2.98)% and (19.17±2.30)%, which were significantly significantly higher than those of untreated cells [(4.86±0.36) %, (3.21±0.48) %, (3.25±0.26)% and (2.66±0.19)%, all P<0.05]. Reduced Akt1 protein expression, elevated Bax/Bcl-2 expression ratio, and elevated caspase-9 and caspase-3 protein expression were detected in lung cancer cells treated with 2.5 mg/mL TanⅡA for 48 h relative to untreated cells Conclusion TanⅡA may inhibit lung cancer cell proliferation in a time- and concentration-dependent manner via the Bax/Bcl-2/caspase-9/caspase-3 pathway.

Objective: To study the axonal effect and the expression of integrin α6β4 during Schwann cell(SC) differentiation and myelination. Methods: Schwann cells were dissociated from the sciatic nerve of neonatal Waster rats and neurons dissociated from spinal cord. Singal cultures and purified populations of SC were cocultured with NC. Four methods (contrast microscope, scanning electron microscopy(SEM), immunocytochemistry method and in situ hybridization ) were used. Results: The separately cultured Schwann cells showed MBP negetive by immunocytochemistry method. But cocultured SC were shown positive. SEM showed that Schwann cells' membrane loop progressively circumnavigated around the axon during myelination, which suggested that the non-myelinating SC(nMSC) transformed to myelinating SC (MSC). In situ hybridization showed integrin α6β4 positive signals only on the outer surface of the Schwann cell-axon unit in SC coculture with NC. Conclusion: The differentiation and maturation of SC depend on axon, and the activity of integrins is expressed by axon. Axonal contact induces the expression of α6β4 during SC myelination, which suggests that integrin α6β4 is an important mediator of interactions of myelinating SC with the basal limina.

Objective To detect the expression of Beclin1 and Bcl2 in invasive pituitary adenomas and to explore the relationship of Beclin1 and Bci2 in invasive pituitary adenomas and the relativity between the 2 genes.Methods 61 specimens were classified into invasive group (32 cases) and non-invasive group (29 cases) according to the comprehensive evaluation of invasive pituitary adenomas.lmmunofluorescence analysis and RT-PCR were adopted respectively to detect the protein and mRNA expressions of Beclinl and Bcl2.The difference and relativity of Beclin1 and Bcl2 expression in invasive group and non-invasive group were analyzed.Results 32 specimens of pituitary adenoma were invasive and 29 were non-invasive.Beclin1 protein and mRNA expressions were lower in the invasive group than in the non-invasive group (P ＜0.01 ).Bcl2 protein and mRNA expressions were higher in the invasive group than in the non-invasive group (P ＜0.01 ).Pearson related analysis showed that Beclin1 mRNA expression was negtively correlated with Bcl2 mRNA expression in the invasive group ( r =-0.42,P =0.028 ).Conclusions Beclinl expression is decreased in invasive pituitary adenomas.The invasiveness of pituitary adenoma is closely related to the high expression of Bcl2 protein and mRNA,and the low expression of Beclin1 protein and mRNA.The inhibition of the autophagy may lead to the enhancement of the invasiveness of pituitary adenomas and that inhibition may come from the interaction of Beclin1 and Bcl2.

Objective To screen out the biomarkers linked to prognosis of breast invasive carcinoma based on the analysis of transcriptome data by random forest(RF),extreme gradient boosting(XGBoost),light gradient boosting machine(LightGBM),and categorical boosting(CatBoost).Methods We obtained the ex-pression data of breast invasive carcinoma from The Cancer Genome Atlas and employed DESeq2,t-test,and Cox univariate analysis to identify the differentially expressed protein-coding genes associated with survival prog-nosis in human breast invasive carcinoma samples.Furthermore,RF,XGBoost,LightGBM,and CatBoost mod-els were established to mine the protein-coding gene markers related to the prognosis of breast invasive cancer and the model performance was compared.The expression data of breast cancer from the Gene Expression Omnibus was used for validation.Results A total of 151 differentially expressed protein-coding genes related to survival prog-nosis were screened out.The machine learning model established with C3orf80,UGP2,and SPC25 demonstrated the best performance.Conclusions Three protein-coding genes(UGP2,C3orf80,and SPC25)were screened out to identify breast invasive carcinoma.This study provides a new direction for the treatment and diagnosis of breast invasive carcinoma.
