Objective To investigate the species of Acaroid mites breeding in the stored traditional Chinese animal medici?nal materials and the relationship between its community and habitats. Methods A total of 30 samples of traditional Chinese animal medicinal herbs were collected from Wuhu City,Anhui Province,China. The mites were isolated by the directly micro?scopic and floatation microscopic examinations,and then identified and counted under a light microscope. Results Acaroid mites was represented in 28 of the 30 samples,and the breeding rate accounted for as high as 93.3%(28/30). Totally,13 spe?cies of Acaroid mites were identified,which belonged to 4 families and 9 genera. The densities of Acaroid mites were top in 6 Chinese herbal medicines,such as corium erinacei,aspongopus,hirudo,pheretima aspergillum,Apostichopus and huechys. The diversity parameters of these six traditional Chinese animal medicinal herbs were calculated. The highest richness indexes were in aspongopus and hirudo,the highest diversity index was in hirudo,and the highest evenness index was in Apostichopus. Conclusions There are Acaroid mites breeding in parts of the traditional Chinese animal medicinal herbs stored in Wuhu. In the storage and processing of Chinese herbal medicines,we should pay attention to the prevention and control of mites.

Objective To explore absorption kinetics of roxatidine acetate hydrochloric (ROX) in intestine of rats.Methods The absorption kinetics and permeability of ROX under different concentrations and different intestinal segments were investigated by double wavelength spectrophotometry via the in situ perfusing method in rats.Results There was no significant difference in Ka of ROX under different concentrations.The absorption rate in rats descended in order of duodenum,jejunum,ileum and colon [(3.87±0.12)×10-2,(2.53±0.18)×10-2,(1.43-±0.10)×10-2,(0.91±0.15)×10-2 · h-1].Conclusion The absorption of ROX in intestine complies with the passive transport mechanism and first order kinetics.ROX is well absorbed in thewhole intestine.

Objective To investigate the role of cytokines combined with CLIF Consortium organ failure score (CLIF-COFs) in determining the prognosis of liver transplant in hepatitis B-related acute-on-chronic liver failure (HB-ACLF) patients.Methods Thirty-seven cases of HB-ACLF patients undergoing liver transplantation were divided into HB-ACLF patients with complications group (n =15) and those without complications (n =22).Plasma were prospectively collected immediately before LT and on the 1st,3rd,5th,7th day after LT in HB-ACLF patients.The serum levels of twenty-seven cytokines were determined by 200 LUMINEX liquid chip technology.Cytokines and CLIF-COFs were analyzed with logistic regression and the receiver operating characteristic to confirm the correlation with the total complications post-LT.Results The serum levels of post-transplant G-CSF and MCP-1 in HB-ACLF patients with complications were higher than those of without complications (P ＜ 0.05).The COX analysis indicated that MCP-1 and CLIF-COFs were predictors of post-LT complications [A UC:0.821,95％ CI:0.668-0.974;AUC:0.738,95％ CI:0.578-0.898].The discriminatory power of MCP-combined with CLIF-COFs [AUC:0.839,95％ CI:0.703-0.975] was better than that of either.Conclusions MCP-1 combined with CLIF organ failure score can better predict the short-term outcomes of liver transplantation in HB-ACLF patients.

Objective To investigation the expressions of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and its receptors in non-small cell lung cancer (NSCLC) and their clinical significances.Methods The serum expression levels of TRAIL in 79 cases of NSCLC and 80 cases of normal subjects were detected by enzyme-linked immunosorbent assay (ELISA).The expressions of TRAIL-R2 and TRAIL-R4 in 42 cases of NSCLC and matched normal tissues were detected by immunohistochemistry.The relationships among TRAIL,TRAIL-R2,TRAIL-R4 and clinicopathologic features of NSCLC were analyzed.Results The expression of TRAIL in NSCLC patients was lower than that in normal human [(994.3 ±293.0)ng/ml vs.(1 141.7 ±266.1)ng/ml,t =3.29,P =0.00].The expression of TRAIL was closely correlated with clinical stage (F =2.28,P =0.00) and differentiated degree (t =5.76,P =0.00).The positive expression rate of TRAIL-R2 in NSCLC was 73.8％ (31/42),significantly lower than that in the normal tissue 100.0％ (42/42) (x2 =3.88,P =0.05).The expression of TRAIL-R2 was closely correlated with clinical stage (x2 =27.89,P=0.00) and differentiated degree (x:=9.50,P =0.00).The positive expression rate of TRAIL-R4 in NSCLC was 81.0％ (34/42),significantly higher than that in the normal tissue 50.0％ (21/42) (x2 =7.34,P =0.01).The expression of TRAIL-R4 was also closely correlated with clinical stage (x2 =17.82,P =0.00) and differentiated degree (x2 =4.47,P =0.03).There was a negative correlation between the expression of TRAIL-R2 and TRAIL-R4 in NSCLC (r =-0.67,P=0.01).Conclusion The decrease of TRAIL and TRAIL-R2 and increase of TRAIL-R4 expression may promote the occurrence and development of NSCLC,and they may provide targets for clinical treatment of NSCLC.

Objective To evaluated the effect of hyperbaric oxygenation therapy(HBO)on the RhoA ex- pression and nerve function after transient focal cerebral ischemia in a rat model of middle cerebral artery occlusion. Methods One hundred and twenty-six healthy Sprague-Dawley rats were used and randomly divided into a sham op- eration group(shame group,n=42),a treatment group(n=42),and a control group(n=42).The animal model of middle cerebral artery occlusion(MCAO)was established by using the Zea-Longa method with the animals in the treatment and the control groups,and sham operation was performed with those in the sham group.HBO was applied to the animals in the treatment group.The RhoA protein expression was observed by using immunohistochemistry technique,and the neurological function was evaluated by Bederson's scale at different time points after MCAO.Re- sults(1)Weakly positive expression of RhoA could be located in bilateral cortex and the basal ganglia in the sham group.The expression of RhoA in the treatment group and control group was increased as early as 6 hours after MCAO when compared with that of the sham group,and peaked at 48 h after MCAO and decreased after then,but was still higher than that of the shame group at 7th day to 14th day after MCAO.It was also found that the expression of RhoA of the treatment group was significantly lower than that of the control group(P

Objective To explore the impact of modified vacuum sealing drainage (VSD) on prevention of tension blisters during treatment of opening fracture wounds.Methods From March 2015 to February 2016,53 patients with 60 open fracture wounds were treated after surgery by VSD at our department.They were 28 males (33 wounds) and 25 females (27 wounds),aged from 24 to 65 years (average,41.1 years).The patients were divided into 2 groups.Group A (33 wounds) were subjected to traditional VSD after surgery while group B (27 wounds) to modified VSD.The mean time from injury to surgery was 5.2 hours (from 2.0 to 8.3 hours).The VSD dressing was first removed to observe whether any tension blisters would appear surrounding the dressing 5 days after surgery.Results Tension blisters appeared around 9 wounds in group A (with an incidence of 27.3％) but around one wound in group B (with an incidence of 3.7％).The difference between the 2 groups was statistically significant (P =0.037).Conclusion In treatment of open fracture wounds,the modified VSD can effectively prevent formation of tension blisters surrounding the dressing while it is used to cover a wound.
