Objective To observe the variation of helper T cell (Th)9/regular T cell (Treg cell) balance in the inflammatory process of hepatitis B virus (HBV) infection.Methods Two hundred patients with chronic HBV infection in Zhejiang Hospital of Integrated Traditional and Western Medicine during August 2011 to June 2012 were divided into four groups according to alanine aminotransferase (ALT) levels.:chronic HBV carriers,chronic hepatitis B (CHB) with mildly [upper limit of normal (ULN)＜ALT＜3 × ULN],moderately (3 × ULN＜ALT＜5 × ULN),or significantly (ALT＞5 × ULN) elevated ALT,with 50 subjects in each group.In addition,30 healthy volunteers were enrolled as healthy controls (HC).ALT levels,HBV DNA,and Th9/Treg levels were measured by automatic biochemical analyzing equipment,real-time fluorescent quantitative polymerase chain reaction and flow cytometry,respectively.Th9/Treg levels of each group were observed.Means between groups were compared by t test,means of multiple groups were compared by one-way analysis of variance.Spearman rank correlation was used for correlation analysis.Results Age,sex distribution and HBV DNA levels of the four groups were comparable (P＞0.05).ALT levels of HC were significantly different from those of mildly,moderately,or significantly elevated ALT (t=8.48,18.41,28.93; all P＜0.05).Th9 cell levels,Treg cell levels and Th9/Treg ratio of HBV infected individuals were significantly different from those of HC (P＜0.05).With the increasing degree of inflammation,proportion of Th9 cells increased and Treg cells decreased gradually.The differences among the four groups were of statistical significance (P＜ 0.05).Th9 cell level was positively correlated with ALT (r=0.804,P=0.01),while Treg cell level was negatively correlated with ALT (r=-0.828,P=0.01).Conclusions Th9/Treg is imbalanced in patients with HBV infection,and closely correlated with ALT levels.

Objective To investigate the correlation between hemorrhagic transformation (HT) and each parameter of blood pressure variability (BPV) in patients with massive cerebral infarction caused by cardioembolic middle cerebral artery occlusion. Methods The patients with massive cerebral infarction caused by unilateral cardioembolic middle cerebral artery occlusion admitted to hospital within 24 h after onset were selected. For patients without revealing HT with head MRI on admission were analyzed retrospectively. According to the results of MRI rescan within 7 days after onset, they were divided into either a HT group or a non-HT group. Al specific parameters of blood pressure were compared and analyzed between the 2 groups, specificaly including initial value (initial), mean value ( mean), maximum value (max), minimum value (min), maximum-minimum difference (max-min), standard deviation (sd), successive variation (sv), and maximum value of sv (svmax) of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Results A total of 146 patients were enroled in the analysis, and 77 (52. 7% ) had HT within 7 d after onset. Al the blood pressure parameters were grouped by quartiles. Multivariate logistic regression analysis showed that after adjusting for age, admission time, baseline National Institutes of Health Stroke Scale score, congestive heart failure, antiplatelet therapy, initial blood glucose, prothrombin time, and international normalized ratio of the patients, SBPmin , SBPmax-min , SBPsv , SBPsvmax , DBPinitial, DBPsd , DBPmax , DBPmax-min , DBPsv , and DBPsvmax had significant independent association with and HT (likelihood ratio test of trend, al P < 0. 05). Conclusions Higher BP level and variability may increase the risk of HT in patients with massive cerebral infarction after cardioembolic middle cerebral artery occlusion. A smooth and slow antihypertensive treatment may need for these patients.

Objective To evaluate the role of nuclear factor-E2 related factor 2 (Nrf2)-antioxidant response element (ARE) pathway in cardio-protection by ischemic or pinacidil postconditioning ( IP,PP) against ischemia-reperfusion (I/R) injury in isolated rat hearts.Methods Fifty-six male SD rats of both sexes weighing 200-250 g were anesthetized with intraperitoneal amobarbital sodium.The isolated rat hearts were perfused in a Langendorff apparatus with Krebs-Hensleit buffer (K-H).Fifty-six isolated rat hearts with I/R injury were randomly divided into 7 groups ( n =8 each):normal control group (group C) ; group I/R; group IP and group PP1-4 postconditioning with 4 different concentrations of pinacidil.After 20 min of equilibration,the perfusion was suspended for 40 min (global ischemia) followed by 60 min of reperfusion in group I/R.In group IP after 40 min of global ischemia,the isolated hearts underwent 6 cycles of 10 s reperfusion and 10 s ischemia followed by 58 min of reperfusion.In group PP1-4 at the end of 40 min of global ischemia,the isolated hearts were perfused with K-H containing pinacidil 5,10,30 and 50μmol/L for 5 min respectively followed by 55 min reperfusion with regular K-H.Left ventricular developed pressure (LVDP) and LVEDP were measured immediately before global ischemia and at the end of 60 min reperfusion.Myocardial specimens were obtained at the end of reperfusion for detection of Nrf2,quinopeoxidoreductase (NQO1),HO-1 and SOD1 mRNA (by RT-PCR) and protein (by Western blot) expression.Results I/R significantly up-regulated Nrf2,NQO1,HO-1 and SODI mRNA and protein expression,decreased LVDP and increased LVEDP in group I/R as compared with group C.IP and 30,50 μmol/L pinacidil postconditioning further significantly increased Nrf2,NQO1,HO-1 and SOD1 mRNA and protein expression and IP,5,10,30,50 μmol/L pinacidil postconditioning significantly increased LVDP and decreased LVEDP as compared with group I/R.Conclusion Ischemic or pinacidil postconditioning can attenuate I/R injury by activating Nrf2-ARE pathway in isolated rat hearts.

Objective To explore the effects of two lubricants on skin preparation from donor site in patients with skin flap transplantation. Methods According to digit number table, 83 patients undergoing wound repair using modified fascia flap were divided into observation group (n=41) and control group (n=42). The former group were treated with Johnson K-Y Lubricant, while the latter with talcum powder. The two groups were compared in terms of the skin flap quality from donor site, pain degree and number of bacteria before and after transplantation. Results There was no significant difference in bacteria number before and after transplantation in the two groups (P>0.05), but the difference between the groups was significant (P<0.01). The flap preparation quality in the observation group was significantly better than that of control group and the pain degree was significantly lower than that of observation group. Conclusion Johnson K-Y Lubricant can significantly improve flap preparation quality and reduce pain.

OBJECTIVE:To investigate the clinical characteristics and gene polymorphism of oxcarbazepine (OXC)- induced Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). METHODS:Retrieved from CNKI,Wanfang,VIP, PubMed,EMBase,SpringerLink and other databases,case reports about OXC-induced severe ADR were summarized and ana-lyzed. RESULTS:Twelve literatures were collected,and 13 case reports about OXC-induced SJS/TEN were obtained. Male had more OXC-induced severe skin ADR than female. ADR mostly occurred during 1-14 d after medication. All patients were cured with treatment of glucocorticoid and antiallergy,without death case. Genotyping for 8 patients were performed and 6 of them showed the presence of HLA-B*1502 allele. While HLA-B alleles of 2 patients were HLA-B*1518/B*4001,which was the variation of HLA-B*1502. CONCLUSIONS:OXC-induced ADR should be monitored closely. Great importance should be attached to patient education and follow-up program. HLA-B*1502 gene detection should be performed to guide rational use of OXC and optimize clini-cal drug use plan.
