Sleep plays an important role in the modulation of endocrine function and energy metabolism;hormone levels are markedly different during a sleepless night compared with a night of normal sleep.Sleep deprivation may change the levels of cortisol,growth hormone(GH)and thyrotropin(TSH)at night.In addition,sleep curtailment disturbs the balance of anorexi- genic(leptin)and orexigenic(ghrelin)factors,and does harmful to glucose tolerance.

Sleep is a common physiological phenomenon of animals.We may have different kinds of sleep disorders in our daily life,such as difficulty falling asleep,insomnia,hypersomnia and changes of sleep patterns,etc.Pain is a subjective response of the body to stimuli of certain degrees.Sleep disorders are closely related to pain:pain can interfere with people's normal physiology and psychology conditions and affect individual's sleep;different kinds of sleep disorders can affect the body' s sensitivity to pain.The relationship between pain and sleep disorders has become one of the most common causality in clinical research.In this paper we summarizes the pathophysiological relation and mutual influence between pain and sleep disorders.

Objective:To explore the clinical features of acute pancreatitis in pregnancy (APIP) and the risk factors for fetal death.Methods:The clinical data of 90 patients with APIP in the Affiliated Hospital of Southwest Medical University were retrospectively analyzed from January 2013 to June 2020. Based on the severity, the patients were classified into MAP groups ( n=41), MSAP groups ( n=33), SAP group ( n=16). According to the presence of fetal deaths, the patients were divided into fetal death group ( n=13) and fetal survival group ( n=77). The clinical characteristics and indicators of patients in each group were compared. Binary logistic regression analysis was performed on the variables with differences between groups to explore independent risk factors for fetal death. The receiver operating characteristic curves of laboratory indicators were drawn to evaluate their diagnostic efficacy. Results:Hyperlipidemia was the main cause in 90 APIP cases (42/90, 46.7%). The levels of LDH, CRP, blood glucose, D2 polymer, albumin and ApoA1, the 1-min and 5-min Apgar scores of neonates were statistically significant among MAP group, MSAP group and SAP group (all P<0.05). There were no maternal deaths in 90 cases and 13 fetal deaths (14.4%). Fetal mortality increased with the severity of APIP. APIP combined with hypertension ( OR=14.742, 95% CI 1.157-187.890, P=0.038), ketoacidosis ( OR=19.587, 95% CI 1.789-214.469, P=0.015) and CRP level ( OR=1.013, 95% CI 1.001-1.025, P=0.031) were risk factors for fetal death. ApoA1 level ( OR=0.118, 95% CI 0.021-0.664, P=0.015) was a protective factor for fetal death. The sensitivity and specificity of ApoA1 for predicting fetal death were 84.6% and 79.2%, the sensitivity and specificity of CRP for predicting fetal death were 76.9% and 84.4%, and the sensitivity and specificity of the combination of the two indicators for predicting fetal death were 100% and 67.5%. Conclusions:The severity of APIP was closely related to fetal death. Hypertension, ketoacidosis and blood level CRP were independent risk factors for fetal death, which should be paid special attention.

Phylogenetic methods have been widely used to detect the evolution of influenza viruses.However, previous phylogenetic studies of influenza viruses do not make full use of the genetic information at the protein level and therefore cannot distinguish the subtle differences among viral genes. Proteotyping is a new approach to study influenza virus evolution. It aimed at mining the potential genetic information of the viral gene at the protein level by visualizing unique amino acid signatures (proteotypes). Neuraminidase gene fragments of some H5N1 avian influenza viruses were used as an example to illustrate how the proteotyping method worked. Bayesian analysis confirmed that the NA gene tree was mainly divided into three lineages. The NA proteotype analysis further suggested there might be multiple proteotypes within these three lineages and even within single genotypes. At the same time, some proteotypes might even involve more than one genotype. In particular, it also discovered some amino acids of viruses of some genotypes might co-reassort. All these results proved this approach could provide additional information in contrast to results from standard phylogenetic tree analysis.

Objective The study of capsaicin (CAP) on the effect and mechanism of indomethacin induced acute gastric mucosal injury in different period.Methods 80 SD rats were randomly divided into 8 groups with 10 rats in each group.The experiment was completed in two phases,and the Ⅰ period was 2 weeks,the Ⅱ period was 4 weeks.The Ⅰ period including group A1 (control group),group B1 (model group),group C1 (CAP group),group D1 (CAP + indomethacin group).The grouping method of the two periods were the same.The rats' gastric mucosa were damaged by indomethacin,and then killed the rats 4 hours later.Last,astric juice was collected to determine the total acidity of gastric acid,counted thegastric mucosal injury index,observed the gastric mucosa pathological injury,detected the expression of TRPV 1、CGRP、MDA、SOD and PGI2.Results The Ⅰ period:the gastric mucosa of group A1 and C1 had no damage.Group D1 compared with group B1,there was no significant difference in gastric mucosa injury (P ＞ 0.05),total acidity decreased significantly (P ＜ 0.05),MDA was no significant difference (P ＞ 0.05),SOD、PGI2 increased significantly (P ＜ 0.05),the expression of TRPV1、CGRP increased significantly (P ＜ 0.05).The Ⅱperiod:the gastric mucosa of group A2 and C2 had no damage.Group D2 compared with group B2,the gastric mucosa injury were significantly reduced (P ＜ 0.05),total acidity decreased significantly (P ＜ 0.05),MDA decreased significantly (P ＜ 0.05),SOD、PGI2 increased significantly (P ＜ 0.05),the expression of TRPV1、CGRP increased significantly (P ＜ 0.05).Conclusion There was no damage to the general morphology and histology of gastricmucosa in rats by intragastric CAP 1 mg/(kg· d) for 2 weeks and 4 weeks.2.It could prevent that indomethacininduced acute gastric mucosal injury in rats by pretreated with CAP 1 mg(kg· d) for 4weeks.

Objective To evaluate the short-term efficacy of total hip arthroplasty combined with subcutaneous osteotomy in the treatment of CroweⅣ hip dysplasia (DDH).Methods From March 2012 to March 2015,14 patients (16 hips) underwent total hip arthroplasty with femoral distraction osteotomy S-ROM femoral stem prosthesis.And we observed its recent efficacy.Results All patients underwent S-ROM prosthesis.The patients underwent transverse osteotomy of the femoral trochanter.The osteotomy length was 2.0-3.5 cm.The average follow-up time was 19 months.And no complications such as dislocation,vascular nerve injury,deep vein thrombosis and infection were observed during the follow-up.The average Harris scores improved from 42.3 preoperatively to 90.4 postoperatively at 9 months after the operation.The average lengths of preoperative limb shortening and postoperative limb shortening were 6.4 cm and 4.3 cm respectively.The X-ray films showed no dislocation of acetabulum and femoral prosthesis.Bone healing was achieved at 6 months after osteotomy.Conclusion This method could be a good choice for Crowe Ⅳ developmental dysplasia.The short-term efficacy is satisfactory.

Objectives To investigate the impact of ischemic preconditioning (IPC) on dynamics of homing of endothelial progenitor cells (EPCs) after renal ischemia reperfusion injury (IR).Methods Sixty male Sprague-Dawley rats were randomly divided into three groups after right-side kidney nephrectomy:for sham-operated rats,lumbotomy without vascular clamping was performed; IR rats were clamped renal blood vessels for 40 minutes while IPC rats were pre-treated with 15 min ischemia and 10 min reperfusion.At 3,12,24 h,and 3 days after reperfusion,the pool of circulating,kidneys,lungs and spleens were harvested.The extent of renal injury was assessed by biochemical and histological examination.The dynamics of homing of EPCs was observed by flow cytometry.Results The rats in IPC group exhibited significant improvements in renal function and morphology.Compared with IR group and sham group,the number of EPCs in blood was increased in the IPC group at 12 h and 24 h after reperfusion (P ＜ 0.05).The number of EPCs in kidney was increased at all times pointin the IPC group and IR group as compared to the sham group (P ＜ 0.05.In addition,EPCs number was increased in IPC group compared with the IR group at 12 h and 24 h [(11.36±0.66)％ vs (6.37±0.69)％,(6.31±0.70)％ vs (4.40±0.60)％,all P＜ 0.05].Compared with IR group and sham group,the number of EPCs in the lung was increased in the IPC groups at 12 h after reperfusion [(2.95±0.66)％ vs (1.78±0.59)％,(1.66±0.61)％,all P ＜ 0.05].The number of EPCs in spleen was increased in the IPC group at 72 h as compared with the IR group and sham group [(0.55±0.06)％ vs (0.34±0.07)％,(0.31±0.06)％,all P ＜ 0.05].Conclusions Endogenous EPCs may home to injured kidney after IPC.EPCs can also gather in the lungs and spleen.
