Conclusion Remifentanil combined with propofol anesthesia can make hemodynamics more stable in patients with acute abdomen complicated with septic shock, and can alleviate inflammation and stress response.

Objective To evaluate the sleep structure of rapid eye movement sleep disorder (RBD) patients and its correlations with emotional state,autonomic nerve system function symptoms,and sleep quality.Methods Twenty-two RBD patients examined in our hospital from October 2014 to May 2016 who complained of behavior disorders and conformed diagnosis by video-polysomnography (v-PSG) were chosen as RBD group;23 healthy gender,age and education-level matched subjects confirmed without RBD by v-PSG were selected as control group.Their emotional state,autonomic nerve function and sleep quality were assessed by center for epidemiological survey depression scale (CES-D),apathy evaluation scale (AES),scale for outcomes in PD for autonomic symptoms (SCOPA-AUT),and scale for outcomes in PD for sleep (SCOPA-SLEEP).The differences in sleep structures,periodic leg movement index (PLMI),apnea hypopnea index (AHI) and arousal index between RBD group and control group were compared.The differences of scores of emotional state,autonomic nerve system function symptoms were compared between the two groups.The correlations of sleep structure with emotional state,autonomic nerve system function symptom,and sleep quality in RBD group were analyzed.Results As compared with those of the control group,the proportion of non-rapid eye movement (NREM)-Ⅰ sleep of RBD group was significantly increased,proportions of NREM-Ⅱ sleep and NREM-Ⅲ sleep were statistically reduced,PLMI,CES-D scores,urinary and digestive system questionnaire and overall scores in the RBD group were significantly increased (P＜0.05).In patients from RBD group,CES-D scores were positively correlated with proportion of NREM-I sleep (r=0.520,P=0.000);nighttime sleepiness questionnaire and overall scores were positively correlated with PLMI (r=0.465,P=0.029;r=0.444,P=0.039);daytime sleepiness scores were negatively correlated with proportion of NREM-Ⅲ sleep (r=-0.480,P=0.041);cardiovascular system symptom was correlated with PLMI (r=0.439,P=0.041).Conclusion RBD patients suffer sleep structure disturbance,depression tendency,digestive and urinary system of autonomic nerve symptoms;sleep quality scores and total scores,cardiovascular system symptoms scores are positively correlated with LMI;daytime sleepiness is negatively correlated with reducing phase Ⅲ sleep,CES-D scores are correlated with increasing NREM-I sleep and unbalanced neurotransmitter,especially,5-TH level.

Objective To summarize our experience with surgical management of renal neoplasm involving inferoir veno cava.Methods We review the data of 115 patients,including 74 male patients and 41 female patients,with renal neoplasm involving venous system between March 1993 and December 2015.The mean age was 52 years old,ranging 22 to 77 years old.The tumor was found in right side in 77 cases and left side in 38 cases.There were 15 patients (13.0％) with renal vein thrombus,38 (33.1％) with infrahepatic thrombus,29 (25.2％) with low retrohepatic thrombus,20 (17.4％) with high retrohepatic thrombus,and 13 (11.3％) with supradiaphragmatic thrombus.The mean age was 52 years old,ranging 22 to 77 years old.The tumor was found in right side in 77 cases and left side in 38 cases.All patients accepted the radical nephrectomy.Primary outcomes were overall survival (OS),and cancer special survival (CSS) in patients with renal cell carcinoma (RCC) estimated by Kaplan-Meier method.Secondary outcome included operative and oncological features,past-operative complications and hospital mortality.Cox proportional hazard model was used to univariate and multivariate analysis for risk factor impacting on OS of RCC patients.Results Complete resections of renal neoplasm with tumor thrombus were achieved in 113 patients (98.3％),2 patients died intraoperatively due to the dropping of thrombus.Postoperative complication rate was 16.8％.Hospital mortality was 2.6％.Mean follow-up interval was 48 months.OS rates at 5-,and 10-year in RCC patients were 66.5％,and 61.8％,respectively.Metastasis was an independent risk factor affecting on OS (P =0.000).However,the level of thrombus was not an risk factor affecting the prognosis.Conclusions Radical resection of renal tumor and caval thrombus is an effective treatment for prolonging survival in patients with RCC extending into venous system.Retrohepatic caval tumor thrombus below or above the main hepatic vein should be dichotomized and managed respectively with diverse techniques.Metastatic rather than the level of thrombus was a risk factor impacting on RCC patient survival.

Objective To investigate the neuroprotective effect of Benztropine on retinal ganglion cells (RGCs) death and optic nerve injury in rats model of non-arteritis anterior ischemic optic neuropathy (rNAION).Methods A total of 25 Sprague-Dawley rats were randomly divided into Benztropine treatment group (n=13)and PBS control group (n=12).The right eye was set as the experimental eye.rNAION model was established by using rose Bengal combined with laser photodynamic method.The rats in the Benztropine treatment group were received intraperitoneal injection with Benztropine 10 mg/kg (0.2 ml) daily for 3 weeks,while the rats in the PBS control group were received intraperitoneal injection with an equal volume of PBS.At 1,3 and 7 days after modeling,the retinal and optic disc conditions of the rats were observed by direct ophthalmoscopy.Retrograde labeling,fluorescence microscopy and transmission electron microscopy were used to observe the survival of RGCs and the damage of the optic nerve myelin and axon at 4 weeks after modeling.The RGCs density and survival rate of the two groups were compared by One-Way Anova.Results At 1 and 3 days after modeling,the optic disc edema was observed in the rats of rNAION model group.At 7 days after modeling,the optic disc edema decreased and the boundary was blurred compared with 3 days after modeling.After 4 weeks,the RGCs density in the PBS group was 308± 194/mm2 and the survival rate was 13.7％.The density of RGCs in the Benztropine group was 1173+868/mm2 and the survival rate was 47.6％.The differences of RGCs density and survival rate were significant between the two groups (F=7.552,8.184;P=0.015,0.012).Myelin disintegration,axon degeneration,onion-like body and gliosis were observed in the optic nerve sections of rNIAON in the PBS group,while the damage ofaxon and myelin structure in the Benztropine group was significantly less than that in the PBS group.Conclusions Benztropine group showed higher RGC survival rate,less damage ofaxon and myelin structure on rNAION model.This study explored the potential neuroprotective effect of Benztropine.

The objective was to investigate the effect of kinsenoside (Kin) treatments on macrophage polarity and evaluate the resulting protection of chondrocytes to attenuate osteoarthritis (OA) progression. RAW264.7 macrophages were polarized to M1/M2 subtypes then administered with different concentrations of Kin. The polarization transitions were evaluated with quantitative real-time polymerase chain reaction (qRT-PCR), confocal observation and flow cytometry analysis. The mechanism of Kin repolarizing M1 macrophages was evaluated by Western blot. Further, macrophage conditioned medium (CM) and IL-1 were administered to chondrocytes. Micro-CT scanning and histological observations were conducted on anterior cruciate ligament transection (ACLT) mice with or without Kin treatment. We found that Kin repolarized M1 macrophages to the M2 phenotype. Mechanistically, Kin inhibited the phosphorylation of IB, which further reduced the downstream phosphorylation of P65 in nuclear factor-B (NF-B) signaling. Moreover, Kin inhibited mitogen-activated protein kinases (MAPK) signaling molecules p-JNK, p-ERK and p-P38. Additionally, Kin attenuated macrophage CM and IL-1-induced chondrocyte damage. , Kin reduced the infiltration of M1 macrophages, promoted M2 macrophages in the synovium, inhibited subchondral bone destruction and reduced articular cartilage damage induced by ACLT. All the results indicated that Kin is an effective therapeutic candidate for OA treatment.
