Objective To explore the anti-apoptotic mechanism of Roux-en-Y gastric bypass (RYGB) through exam?ine the postoperative change of adiponectin levels and expressions of pancreatic islets relative apoptotic protein. Methods Sixty SD rats were randomly allocated to RYGB group (n=20), type 2 diabetes mellitus group (T2DM, n=20) and normal con?trol group (NC, n=20). Rats in the NC group were fed with normal diet. In order to make type 2 diabetic rat models, the rats in the T2DM and RYGB groups were fed with high fat diet (22.19 kJ/g) combined with administration of intraperitoneal strep?tozotocin injection (STZ, 30 mg/kg) on the 13th day of high fat diet. RYGB operation were performed in RYGB group and sham-operation were performed in the T2DM and NC groups when diabetic model was contructed. Rats were weight preoper?atively and at the 7th, 14th, 21st days after operations. Fasting plasma glucose and adiponectin (ELISA) were measured preoper?atively and at 21st day postoperatively. Protein expressions of Bcl-2,Caspase 8 and Caspase 9 in pancreatic islets were ex?amined by immunohistochemistry at the 21st day postoperatively. Results Body weights do not vary significantly among three groups preoperatively. Compared to rats in the NC group, fast plasma glucose level was higher but adiponectin was low?er in rats in RYGB and T2DM groups. Body weights of rats in RYGB group decreased significantly compared to those of rats in NC and T2DM groups postoperatively. Compared to rats in T2DM group, fasting glucose level was lower while adiponectin concentrations was higher in rats in RYGB group but no differences of these parameters were seen in rats in NC group at the 21st day postoperatively. Expression of Bcl-2 in RYGB group was significantly elevated while expressions of Caspase 8 and Caspase 9 were significantly decreased compared to those in T2DM group postoperatively. Conclusion Adiponectin levelswas elevated;expressions of Bcl-2 was increased;expressions of Caspase 8, Caspase 9 were decreased upon RYGB opera?tion in T2DM model. RYGB might reduce pancreatic islets apoptosis through mitochondrial pathway.

Objective:
To search new prognosis-related genes in gastric cancer by analyzing the high-throughput sequencing data of gastric cancer in TCGA database, and then provide data support for future studies.
Methods:
The RNA-seq expression matrix data and patient-related clinical data from 375 gastric cancer tissues and 45 adjacent noncancerous tissues were downloaded from the TCGA database. The data were collated and standardized based on the R language. The difference of gene expression was analyzed by the edgeR and DEseq software packages. The survival analysis of obtained differential genes was performed by the univariate and multivariate COX regressions combined with clinical data of patients, and then the genes with clinical significance were screened out.
Results:
A total of 364 differential genes were obtained by the edgeR and DEseq analysis. Subsequently, the functional enrichment analysis found that these genes were mainly involved in protein digestion and absorption, cytochrome P450 system of drug and exogenous substance metabolism, chemical carcinogenesis, gastric acid secretion and so on. The univariate COX regression analysis showed that FAP, FAT3, PDK4 and ZNF365 genes had significant influences on the prognosis of gastric cancer patients. The multivariate COX stepwise regression analysis showed that the risk model constructed by FAP and PDK4 could predict the prognosis of gastric cancer patients.
Conclusion:
FAP, FAT3, PDK4 and ZNF365 genes may be the prognostic markers of gastric cancer, which may provide data supports for future clinical and basic studies.

OBJECTIVE:
To investigate the role of Numb in regulating mammalian target of rapamycin (mTOR) complex 1 (mTORC1) signaling pathway.
METHODS:
Male BALB/C mouse models of acute kidney injury (AKI) were subjected to intravenous injections of Numb-siRNA or NC-siRNA with or without intraperitoneal cisplatin injections. After the treatments, the expressions and distribution of Numb and megalin in the renal tissues of the mice were detected with immunohistochemistry, and the renal expressions of Numb, S6, p-S6, S6K1, p-S6K1, 4EBP1 and p-4EBP1 were examined with Western blotting. The proximal renal tubular epithelial cells were isolated from the mice transfected with Numb-siRNA for in vitro culture. In NRK-52E cells, the effects of amino acid stimulation, Numb knockdown, and V1G1 overexpression, alone or in combination, on expressions of Numb, S6 and p-S6 were detected with Western blotting; the expressions of AMPK and p-AMPK were also detected in transfected NRK-52E cells, mouse kidneys and cultured mouse renal tubular epithelial cells.
RESULTS:
In BALB/C mice, injection of Numb-siRNA caused significant reductions of Numb and p-S6 expressions without affecting megalin expression in the renal proximal tubules (P < 0.05). Cisplatin treatment obviously upregulated p-S6K1 and p-4EBP1 expressions in the kidneys of the mice (P < 0.05), and this effect was significantly inhibited by treatment with Numb-siRNA (P < 0.05). In NRK-52E cells, amino acid stimulation significantly upregulated the expression of p-S6 (P < 0.05), which was strongly suppressed by transfection with Numb-siRNA (P < 0.05). Numb knockdown inhibited AMPK activation in NRK-52E cells, mouse kidneys and primary proximal tubular epithelial cells (P < 0.05). Numb knockdown significantly downregulated V1G1 expression in NRK-52E cells (P < 0.05), and V1G1 overexpression obviously reversed the inhibitory effect of Numb-siRNA on S6 phosphorylation (P < 0.05).
CONCLUSION
Numb promotes the activation of mTORC1 signaling in proximal tubular epithelial cells by upregulating V1G1 expression.

Objective To evaluate the therapeutic effects of electromyography feedback functional electrical stimulation (FES) on plantar pressure of stroke patients. Methods 18 subjects were included in this study, who were with drop foot resulting from stroke, but could partly dorsiflex the paretic limb's ankle (Manual Muscle Test >2). They were tested on the RS-footscan plate before and after stimulation. The plantar pressure data of paretic foot and walking velocity before and after stimulation were compared. Results The initial touchdown points of most paretic foot were changed from Meta (metatarsal) 5 to heel; the time of initial touchdown of heel medial and heel lateral significantly improved, while that of Meta 3, Meta 4 and Meta 5 significantly delayed; the peak force, impulse and contact area of the heel significantly improved after stimulation (P<0.05). At the same time, the time of initial touchdown of heel medial and heel lateral of nonparetic foot significantly improved (P<0.05). Conclusion Electromyography feedback functional electrical stimulation can improve the gait pattern and the stability of patients with stroke.

Objective To explore the impact of different hemoglobin on postoperative cognitive functions in female patients underwent laparoscopic surgery. Methods 215 female patients who were underwent laparoscopic total hysterectomy or laparoscopic myomectomy from January 2016 to December 2016 in our hospital were selected. The patients were divided into 3 groups according to their hemoglobin:Group N with normal hemoglobin ,Group A with hemoglobin concentration of 9 ~ 11 g/L ,and Group B with hemoglobin concentration of 6 ~ 9 g/L. Same anesthesia and recovery plan were performed in all patients. Basic and operative information were recorded. The score of MoCA on the day before surgry ,the day after surgry ,3 days after surgry and 30 days after surgry were recorded. Blood samples were collected on the day before surgry and the day after surgry for the determina-tion of serum S-100β protein and IL-6 concentrations. Results No significant difference was found in basic and operative information among three groups. The recovery time was much longer in Group B than that in Group N. No difference were found among three group in the score of MoCA on the day before surgry and 30 days after surgry ,while the score in the day after surgry and 3 days after surgry were lower in Group B com-pared with Group N. The incidence of POCD were higher in Group B compared with Group N. Compared with the day before surgry ,the concentration of serum S-100β protein and IL-6 were much higher. And compared with Group N ,the concentration of serum S-100β protein was higher in Group A and B in the day after surgry , while IL-6 was higher in Group B. The concentration of serum S-100βprotein and IL-6 were much higher in Group B compared with Group A in the day after surgry. Conclusion Female patients with hemoglobin concen-tration of 6 ~ 9 g/L are susceptible to POCD ,which might be contributed by operative central nerve system damage induced by excessive inflammation.
