Objective:To assess the characteristics change of sleep architecture in drug naive patients with schizophrenia,compared with healthy control.Methods:The key words including schizophrenia and sleep architecture (or sleep structure or sleep disturbance or polysomnogram and so on) were used to search literatures in MEDLINE,Embase,Springer,PsychINFO,google scholar,Wanfang data,published from 1980 to 2015.Fifteen studies that compared sleep architecture in drug naive patients with schizophrenia and healthy control were included.Literature quality evaluation was performed with the Newcastle-Ottawa Scale.The meta-analysis was performed by using Stata13.0 software.Results:Compared to healthy control,the total sleep time decreased (P ＜ 0.01),the sleep latency increased (P ＜ 0.01),the sleep efficiency decreased (P ＜ 0.01),and the rapid-eye-movemem (REM) sleep latency increased (P ＜ 0.01) significantly in drug naive patients with schizophrenia.The proportion of stage1 was increased,and the proportions of stage4 and slow wave sleep stage were decreased,the differences between case and control were statistically significant.Conclusion:In the control of drug effects,patients with schizophrenia may have poorer sleep quality of be poorer than healthy controls,such as the decreased total sleep time,specifically slow wave sleep,prolonged sleep latency and decreased sleep efficiency.

Objective: To evaluate the effects of total extraperitonal herniorrhaphy on pain and effusion in patients with surgical area. Methods: The clinical data of 58 cases of inguinal hernia admitted to the First Hospital of Shanxi Medical University from January 2017 to January 2018 were retrospectively analyzed.Complete extraperitoneal inguinal oblique hernia repair was performed under laparoscopy under general anesthesia.The patients were divided into two groups by the single or double of admission date number.The observation group(A group, 32 cases) received post-operative intraoperative pressure homemade ice bags, the control group(B group, 26 patients) was placed in normal temperature saline bag after operation.The degree of pain in patients was evaluated by numerical scoring method.The time of exit, discharge, accumulation rate and recurrence rate of hernia were analyzed. Results: The differences in pain score, pain score during floor movement, and regional efflux rate between A group and B group were statistically significant[(2.11±0.97)points vs.(2.45±1.21)points, (2.63±1.89)points vs.(2.76±1.95)points, 0 case vs.2 cases, t=2.745, 4.189; χ²=1.15, all P<0.05]. The time of discharge from hospital and discharge after surgery in A group and B group were (19.16±9.22)h vs.(19.76±10.52)h, (34.85±7.43)h vs.(37.56±8.91)h, the difference was not statistically significant(t=1.790, 0.834, all P>0.05). Conclusion After laparoscopic repair of total extraperitonal herniorrhaphy, the area ice pack can achieve the purpose of relieving pain in the surgical area and reducing the accumulation of fluid in the surgical area.

Objective To investigate the effects of the serum from rats with hemorrhagic shock and Shenfu injection, on the expression of endothelial cell protein C receptor (EPCR) in human umbilical vein endothelial cells (HUVECs) cultured with rat serum. Method The soluble endothelial protein C receptor (sEPCR) in supernatant, the expression of EPCR mRNA and protein level of EPCR in HUVECs were detected by using enzyme linked immunosorbent assay ( ELISA), reverse transcription polymerase chain reaction (RT-PCR), and western bloting (WB) in normal control group, hemorrhagic shock serum (3 h, 12 h, 24h, 72 h) group, and Shenfu-treated (3 h, 12 h, 24 h, 72 h) group, respectively. Results The mean levels of sEPCR and the expression of EPCR mRNA were significantly higher in hemorrhagic shock serum (12 h, 24 h) group, and Shenfu -treated(24 h)group than those in normal control group (all P ＜0.01 ),the mean levels of sEPCR and the expressions of EPCR mRNA were significantly higher in Shenfu-treated ( 12 h) group than those in normal control group ( all P ＜0. 05 ), while the levels of protein were lower in hemorrhagic shock serum ( 12 h, 24 h) group and in Shenfu-treated(24 h)group than those in normal control group ( both P ＜0.01 ), and the level of EPCR protein was lower in Shenfu-treated( 12 h) group than that in normal control group ( P ＜ 0. 05) . The mean levels of sEPCR and the expressions of EPCR mRNA were significantly lower in Shenfu-treated ( 12 h, 24 h) group than those in hemorrhagic shock serum ( 12 h,24 h) group (all P ＜0.05), while the levels of EPCR protein were higher in Shenfu-treated ( 12 h, 24 h)group than those in hemorrhagic shock serum ( 12 h, 24 h) group ( P ＜ 0.05 ). Conclusions These data suggest that Shenfu injectio could affect the expression of EPCR mRNA and the level of EPCR protein, thereby it might be effective in prevention of development of hemorrhagic shock.

Objective: Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders in children and adolescents, often accompanied by motor function disorders. Sarcopenia not only has skeletal muscle dysfunction but also has neurocognitive dysfunction. At present, there is no research to explore the relationship between ADHD and skeletal muscle function. The purpose of this study is to explore whether there is a causal effect between ADHD and sarcopenia. Methods: In this study, genome-wide association study data of ADHD, appendicular lean mass (ALM), hand grip strength, and walking pace (WP) were extracted from public databases. The bidirectional two-sample Mendelian randomization (MR) method was employed to investigate the correlation between ADHD and sarcopenia-related indicators, and the inverse-variance weighted analysis as the primary analysis method. Results: Based on the forward MR analysis, a potential causal relationship exists between ADHD and ALM (odds ratio [OR]=1.020, 95% confidence interval [CI]: 1.012–1.029, p<0.001). The reverse MR analysis indicates a link between WP and the risk of ADHD (OR=2.712, 95% CI: 1.609–4.571, p<0.001), with an accelerated WP increasing the likelihood of ADHD. Nevertheless, other MR analysis results did not show significant differences. Conclusion The findings of this study indicate an intricate causal relationship between ADHD and sarcopenia, suggesting the absence of a clear link. WP may be used as one of the indicators to evaluate the risk of ADHD. At the same time, we should pay more attention to the ALM of ADHD patients.

Objective:The Qinzhi Zhudan formula(QZZD)exhibits a prominent therapeutic effect in the treatment of vascular dementia(VaD).This study combined a network pharmacology approach and experimental validation to identify the underlying biological mechanism of QZZD against VaD.Methods:Male Wistar rats received bilateral common carotid artery occlusion(BCCAO)surgery,and after 4 weeks of intragastric administration of QZZD,the therapeutic effect was assessed using the Morris water maze test and cerebral blood flow(CBF)assessment.Hematoxylin and eosin staining,Nissl staining,and electron microscopy were used to measure the histopathological changes in the neurons of rats.The effect of QZZD treatment on hippocampal neurotransmitters was assessed by high-performance liquid chromatography with electrochemical detection and liquid chromatography mass spectrometry.Immunofluorescence was used to observe VaD-induced microglia activation.The inflammatory cytokine levels were assessed by enzyme linked immunosorbent assay.Western blot was used to examine the TNFR1-mediated TNF pathway,which was screened out by network pharmacology analysis.Results:QZZD treatment alleviated pathological changes and neuronal damage in VaD rats and atten-uated their cognitive impairment.In addition,QZZD increased CBF and the expression of acetylcholine and 5-hydroxytryptamine in the hippocampal region.Notably,QZZD inhibited microglial activation and the expression of IL-6 and TNF-a.Network pharmacology and western blot indicated that QZZD inhibited the levels of TNFR1,NF-KBp65,p-ERK,TNF-α,and IL-6,which are related to the TNFR1-mediated TNF signaling pathway.Conclusion:QZZD clearly improved learning and memory function,reduced brain pathological damage,elevated CBF and hippocampal neurotransmitter levels,and alleviated neuroinflammation of VaD rats partly by inhibiting the TNFR1-mediated TNF pathway,indicating its potential value in the clinical therapy of VaD.
