Objective: To investigate the effect and significance of GSK-3β inhibitor(LiCl)and RANK-RANKL on the renal tissue of diabetic nephropathy(DN) rats. Methods: SD rats were divided into normal control group (NC), DN model group (DN) and GSK-3β inhibitor intervention group (LiCl). Twenty-four hour urine protein of rats were determined by Coomassie brilliant blue. Kidney tissue sections were stained by HE. The expression of GSK-3β, RANK and RANKL protein were determined by immunohistochemistry staining. The mRNA of GSK-3β, RANK, RANKL was detected by RT-qPCR. Results: Compared with NC group[(14.72±3.37)g], the level of 24-hour urinary protein[(154.17±20.65)g] increased significantly in DN group; compared with DN Group, the level of 24-hour urinary protein [(107.22±31.15)g]decreased in LiCl group(P<0.05). Compared with NC group(2.10±0.60, 1.10±0.20, 1.21±0.20; 19.52±3.20, 1.80±1.10, 1.81±0.50), the pathological changes of renal tissues of DN group aggravated, the mRNA and expression of protein of GSK-3β, RANK and RANKL increased(9.10±2.15, 8.95±2.40, 9.90±2.60; 32.70±7.20, 19.20±4.32, 20.92±5.90); compared with DN group, the pathological changes of renal tissues of LiCl group alleviated, mRNA and the expression of protein of factors above declined(2.70±0.80, 2.32±0.65, 3.58±1.10; 22.35±3.25, 4.20±2.42, 5.90±2.36; P<0.05). Conclusion RANK and RANKL play an important role in the development of DN, LiCl influence Wnt and NF-κB signal pathway down-regulating RANK and RANKL to suspend development of diabetic nephropathy.

Objective: The optimal sequence of adjuvant chemoradiation in the treatment of advanced endometrial carcinoma (EC) remains unclear. We sought to evaluate the outcomes of patients treated with chemoradiation in sandwich fashion (chemotherapy-radiotherapychemotherapy; CRC), versus those treated sequentially (chemotherapy-radiotherapy; CR) (radiotherapy-chemotherapy; RC), to determine if there is a survival advantaged associated with a particular treatment sequence. Methods: A multicenter retrospective analysis of patients with stage III and IV EC from 2000-2018 was conducted. Inclusion criteria were patients who had undergone comprehensive surgical staging/tumor debulking; followed by adjuvant chemoradiation. Differences in the frequencies of adverse events were evaluated using Pearson's χ 2 test. Progression free survival (PFS) and overall survival (OS) rates were calculated using Kaplan-Meier estimates. Results: Final analysis included 152 patients; 36.8% (n=56) CRC, 28.9% (n=44) CR, and 34.2% (n=52) RC. Histology included 44.0% endometrioid, 47.5% serous and 8.5% clear cell tumors. There was no difference in the frequency of histology (p=0.973), stage (p=0.143), cytoreduction status (p=0.932), or treatment delays (p=0.571) between adjuvant therapy sequences. The most frequent location of disease recurrence was abdomen. The median PFS favored CRC versus CR or RC (36-months vs. 22-months and 24-months, respectively) (p=0.038), as did the median OS (48-months vs. 28-months and 34-months, respectively) (p=0.003). CRC demonstrated superiority over CR and RC sequencing in terms 3-year PFS (55% vs. 34% and 37%, respectively) and 3-year OS (71% vs. 50% and 52%, respectively). Conclusions Adjuvant chemoradiation delivered in CRC sequence was associated with improvements in both PFS and OS compared to alternant therapy sequencing.

OBJECTIVETo observe postoperative glucose tolerance, gastric inhibitory polypeptide (GIP) , and glucogan-like peptide-1 (GLP-1) in normal glucose level dogs after undergoing gastric bypass procedures, and to explore the mechanism of gastric bypass procedures to treat type 2 diabetes.

METHODSThe 6 dogs with normal glucose tolerance had undergone gastric bypass procedures, and measure preoperative and postoperative oral and intravenous glucose tolerance (at time points 1, 2, and 4 weeks) through changes in blood glucose, insulin, gastric inhibitory polypeptide (GIP), glucagon-like peptide-1 (GLP-1), and measure preoperative and postoperative week 4 pancreatic tissue morphology.

RESULTSSecond weeks after operation, the fasting blood sugar was (3.58 ± 0.33) mmol/L, and significantly lower than preoperative (t = 3.571, P < 0.05). The GLP-1 level before oral glucose tolerance test (OGTT) and 30 minutes after OGTT were (0.90 ± 0.21) and (0.91 ± 0.19) pmol/L respectively, and significantly higher than preoperative (t value were -3.660 and -2.971, P < 0.05). GLP-1 levels began to decrease in the second week after surgery. After 4 weeks, the index recovered to the preoperative level. Four weeks after surgery when compared with preoperative, islet morphology, islet number (6.8 ± 0.8 and 7.1 ± 0.8 respectively) and islet cells (16.7 ± 2.5 and 16.3 ± 3.1 respectively) did not change significantly (P > 0.05).

CONCLUSIONGastric bypass procedures could be briefly affect normal glucose tolerance in dogs' blood glucose, insulin and diabetes-related gastrointestinal hormones.

Avian, swine and other zoonotic influenza viruses may cause disease with significant impact in both human and animal populations. The Asia Pacific Strategy for Emerging Diseases (APSED), long recognizing the increased global impact of zoonotic diseases on human populations, has been used as the foundation for improving national preparedness and regional coordination for response to zoonotic diseases in the World Health Organization (WHO) Western Pacific Region.1 APSED encourages multisectoral coordination at the human–animal–environment interface as the primary action required for zoonotic disease control.2 In this article we emphasize the effectiveness of these multisectoral collaborations in responding to zoonotic diseases at the regional and country level, using avian influenza as an example.
