The problem of single educational origin structure generally existed in affiliated hospitals of universities, which could not only affect the academic vitality and scientific research innovation ability of the hospital, but also may lead to restricted discipline development. Through measures such as reforming the hospital-retention policy, expanding recruitment channels, strengthening talent cultivation and formulating supporting policies, Union Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology has successfully increased the proportion of doctors graduated from other hospitals, promoted the diversification of educational origin structure. The author suggested that affiliated hospitals of universities should establish a diversified human resources allocation system during the recruitment stage, give support policies to employees graduated from other hospitals, pay attention to the balanced development of sub-specialties, and expand the educational origin of existing employees, so as to promote the healthy development of clinical disciplines.

[Abstract] Objective: To explore the pathogenosis and prognostic markers for non-smoking female lung cancer patients with bioinfor‐ matics analysis and functional prediction of potential lung cancer associated genes in female non-smokers. Methods: Data for nonsmoking female patients with lung cancer were downloaded from the Gene Expression Omnibus (GEO) database and the differentially expressed genes (DEGs) were identified using GEO2R. DAVID online data base was used to perform gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG), and STRING online software was used to perform protein-protein interaction (PPI) analysis; then the plug-in (M-CODE) was used to screen the key DEGs; finally, GEPIA and Kaplan-Meier plotter were used to perform function prediction and prognosis analysis of key DEGs. Results: A total of 160 DEGs were screened, including 54 up-regulated and 106 down-regulated genes; GO enrichment analysis showed that these DEGs were mainly related to neovascularization, single cell adhesion, positive regulation of GTPase activity and signal transduction (all P<0.05). KEGG pathway analysis revealed that DEGs were mainly involved in cell adhesion molecules (CAMs), leukocyte transendothelial migration, tight junction and endocytosis (all P<0.05); PPI network analysis revealed 8 key DEGs, including TIE1, PECAM1, CLDN5, VEGFD, ICAM2, ESAM, EMCN and ROBO4. Conclusion: TIE1, CLDN5, ICAM2, ESAM, VEGFD and ROBO4 may be the research targets of the pathogenesis of non-smoking female lung cancer patients. PECAM1 and EMCN may be the new bio-markers to predict the progression and prognosis of nonsmoking female lung cancer patients.

Objective To investigate the X-ray gray scale changes of calcium sulfate and evaluate its clini-cal effect in traumatic fracture treatment. Methods 23 traumatic fracture cases were treated from September 2014 to January 2016 in our hospital. The degradation rate of calcium sulfate was evaluated by X ray assay. Results Af-ter surgery,about 69%remnants at 1 week,53%remnants at 2 weeks,26%remnants at 4 weeks,7%remnants at 6 weeks were observed,while no remnants were found at 8 weeks after surgery. The initial time window of callus appearance was 3 to 9 weeks and the mean time was(6.5 ± 1.6)weeks. The fracture union time was 8 to 24 weeks and the mean time was(15.0 ± 5.2)weeks. One patient with distal humeral comminuted fracture had non-infec-tious delayed healing wound.One case of hemolytic staphylococcus in incision was cultured. Conclusion Calcium sulfate degrades rapidly,cautions should be taken for the application in the superficial bone.

OBJECTIVE: To explore the correlation between diabetic nephropathy (DN) and cognitive impairment through examining the cognitive function and the metabolism of the cerebrum in Type 2 diabetes mellitus patients at different stages of renal function.
 METHODS: Eighty six patients with Type 2 diabetes mellitus (T2DM) were enrolled for this study. According to the urinary albumin excretion rate (UAER), the patients were divided into a T2DM without DN group (DM group, n=33), an early DN group (DN-III group, n=26) and a clinical stage group (DN-IV group, n=27). Thirty healthy adults were selected as a control group (NC group). Biochemical indexes and UAER were measured, and glomerular filtration rate (GFR) was detected by single-photon emission computed tomography (SPECT). The cognitive function was measured by Montreal Cognitive Assessment (MoCA, Beijing version) and mini-mental state examination (MMSE). The peak areas of N-acetylasparte (NAA), creatine (Cr), choline-containing compounds (Cho) were detected by proton magnetic resonance spectroscopy (1H-MRS).
 RESULTS: 1) There was no statistical difference in MMSE scores between the DM group and the control group. The scores of MoCA in the DN-III group or in the DN-IV group were significant less than that in the NC group (F=3.66, P<0.05); 2) There was significant difference in left N-acetylaspartate (LNAA), left choline (LCho) among the diabetes groups. Compared with the DM group, the level of LNAA was decreased significantly (t=3.826, P<0.05) while the LCho was increased significantly (t=4.373, P<0.05) in the DN groups, with statistic difference between the 2 groups (t=3.693, P<0.05); 3) The MoCA scores of T2DM patients were negatively correlated with UAER (r=-0.285, P<0.05), while positively correlated with GFR (r=0.379, P<0.05); 4) Logistic regression analysis indicated that UAER and GFR were the major risky factors for diabetic cognitive impairment.
 CONCLUSION Diabetic cognitive impairment is closely correlated with the nephropathy in patients with Type 2 diabetes. With the decline in glomerular filtration function, the cognitive disorder tends to be aggravated. The hippocampal brain metabolism may have some changes in left side of Cho/Cr in patients with diabetic nephropathy.

Background and purpose: Bladder cancer is the most common urological malignancy in our country which seriously threatens human health, and its incidence increased year by year. This study aimed to investigate the effects of hinokitiol on the proliferation, apoptosis and autophagy in human bladder cancer cell lines. Methods:CCK-8 assays were performed to analyze the effects of hinokitiol on the proliferation of J82 cells. Apoptosis rate was determined by lfow cytometry. Cleaved caspase 3, LC3 and P62 protein expression was determined using Western blot. EGFP-LC3 microscopy assay was performed to assess autophagy. Results: Hinokitiol significantly inhibited the proliferation of J82 cells and induced cell apoptosis via caspase pathway. The apoptosis effect of hinokitiol could be partially antagonized by Z-VAD-FMK. Hinokitiol induced autophagy of J82 cells, increased LC3 expression and down-regulated P62 expression. 3-MA is able to rescue Tet-induced cell death. Conclusion:Hinokitiol can inhibit the proliferation of J82 cells and induce cell apoptosis via autophagy activation.

Objective:To establish a method for the determination of residual triethylamine in tenofovir disoproxil fumarate. Methods:The residual treithylamine was determined by GC with an Agilent DB-624 capillary column(30 m × 0. 53 mm,3 μm)and an FID detector. The carrier gas was nitrogen and the flow rate was 2. 0 ml · min-1 . The oven temperature was programming in-creased. The initial column temperature was 50℃,and then raised to 220℃ at a rate of 10℃·min-1 ,and maintained 4 min. Trieth-ylamine was quantified by an external standard. Results:The calibration showed a good linearity within the range of 53. 02-742. 34 μg ·ml-1 for triethylamine. The correlation coefficient was 0. 999 8. The recoveries were within the range of 96. 52%-102. 27%. The relative standard deviation(RSD)was 2. 42%(n=9). Conclusion:The method has good specificity,repeatability and sensitivity, which can be used in determining the content of residual trietbylamine in tenofovir disoproxil fumarate.

BACKGROUNDThe purpose of this retrospective study was to compare the surgical outcomes of simple discectomy and instrumented posterior lumbar interbody fusion (iPLIF) in patients with lumbar disc herniation and Modic endplate changes. Our hypothesis was that iPLIF could provide better outcome for patients with refractory lumbar disc herniation and Modic changes (LDH-MC).

METHODSNinety-one patients with single-segment LDH-MC were recruited. All patients experienced low back pain as well as radicular leg pain, and low back pain was more severe than leg pain. Forty-seven patients were treated with discectomy and 44 were treated with iPLIF. The outcomes of both low back pain and radicular leg pain using visual analogue scale (VAS) as well as the clinical outcome related to low back pain using Japanese Orthopaedic Association (JOA) score were assessed before and 18 months after surgery, respectively.

RESULTSBoth low back and leg pain were significantly improved 18 months after simple discectomy and iPLIF. Compared to patients undergoing simple discectomy, low back pain was significantly reduced in patients undergoing iPLIF, but there was no significant difference in leg pain between two groups. Solid fusion was achieved in all patients who underwent iPLIF.

CONCLUSIONSIn patients with LDH-MC, iPLIF can yield significantly superior outcome on the relief of low back pain compared to simple discectomy. Simple discectomy can relieve radicular leg pain as efficient as iPLIF. Accordingly, iPLIF seems to be a reliable treatment for patients with LDH-MC and predominant low back pain.
