Objective:To investigate the mechanism of liver and lung injury in mouse septic models.Methods:Twenty-four male Kunming mice were subjected to cecal ligation and puncture(CLP)or sham operation.The permeability of microvasculature,water contents,activities of myeloperoxidase(MPO)and the apoptosis of microvascular endothelial cells in lung microvasculature and liver sinus were examined 3 h and 12 h after operation.Results:Both the liver and lung showed a significant increase in microvessel permeability at 12 h in CLP group compared with sham operation group.MPO activity and water content in CLP group were obviously higher than those in the sham operation group.The apoptosis of lung microvascular endothelial cells at 12 h in CLP group(5.03?0.92)% was significantly higher than that of control group(3.48?1.21)%(P

Objective To observe the clinical efficacy of self-prescribed Guchong Decoction combined with Ferroids for the treatment of iron deficiency anemia (IDA)patients with unconsolidation of thoroughfare and conception vessels. Methods A total of 70 IDA patients with unconsolidation of thoroughfare and conception vessels were randomized into treatment group and control group,35 cases in each group. The control group was given oral use of Ferroids, and the treatment group was treated with self-prescribed Guchong Decoction combined with Ferroids. One month constituted a treatment course,and both groups were treated for 2 courses. Before and after treatment,we compared the parameters of blood routine test for red blood cells(RBC),hemoglobin (HGB), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), MCH concentration (MCHC),white blood cells(WBC)and platelets,as well as reticulocytes(Ret)and iron metabolism indexes including serum iron(SI),serum ferritin(SF),and total iron-binding capacity(TIBC). The adverse reaction was monitored during the treatment. After treatment,both western medicine clinical efficacy and traditional Chinese medicine (TCM)syndrome clinical efficacy of the two groups were evaluated. A 3-month follow-up was carried out after treatment to evaluate the recurrence rate. Results(1)Drop-out occurred in one case from the treatment group and in 2 cases from the control group because of short-term medication suspension.(2)After treatment for 2 months, western medicine clinical cure rate of the treatment group was 82.4％ and that of the control group was 60.6％, and TCM syndrome clinical cure rate of the treatment group was 94.1％ and that of the control group was 51.5％,the difference being significant(P < 0.05 or P < 0.01).(3)The levels of RBC,HGB,Ret, MCV, MCH, MCHC, and WBC of the two groups were obviously increased after treatment (P < 0.01), and PLT level was markedly decreased (P < 0.01)as compared with those before treatment,but the inter-group differences after treatment were insignificant (P > 0.05). (4)After treatment,iron metabolism indexes of SF and SI of the two groups were significantly increased (P < 0.01), and TIBC of the treatment group was significantly decreased (P < 0.01). The treatment group had stronger effect on increasing SF and SI and on decreasing TIBC than the control group (P < 0.05 or P < 0.01). (5)The incidence of adverse reaction and the recurrence rate in the treatment group were lower than those of the control group,the difference being significant (P< 0.01). Conclusion Guchong Decoction combined with Ferroids is effective for the treatment of IDA with unconsolidation of thoroughfare and conception vessels through relieving symptoms rapidly, reducing gastrointestinal adverse reaction,and decreasing recurrent rate.

OBJECTIVETo investigate and compare the effectiveness and safety of 80-W GreenLight laser vaporization and GreenLight high-performance system (HPS) 120-W laser vaporization for the treatment of benign prostatic hyperplasia (BPH) in high-risk patients.

METHODSWe allocated 290 high-risk patients with BPH to two groups to receive 80-W (n = 220) and HPS 120-W GreenLight laser vaporization (n = 70). We recorded and compared the pre-, intra- and post-operative clinical data of the two groups.

RESULTSThe operations were successful in both of the groups. There were statistically significant differences in the prostate volume, IPSS, Qmax and PVR before and after surgery (P < 0.01), but not between the two groups (P > 0.05). The operation time, lasing time and energy consumption were (56.5 +/- 22.6) min, (31.2 +/- 10.3) min and (159.8 +/- 29.0) kJ in the 80-W group, as compared with (45.1 +/- 20.4) min, (24.6 +/- 8.3) min and (134.2 +/- 23.3) kJ in the 120 W group, with significant differences between the two (P < 0.01).

CONCLUSIONGreenLight laser vaporization of the prostate is a safe and effective procedure for the treatment of BPH, and the new HPS 120-W laser therapy, with its advantages of easier operation and shorter surgical time, is an even better minimally invasive option for elderly high-risk patients.

The purpose of the present study was to investigate the effects of different concentrations of ethanol on action potential (AP) in the isolated rat myocardium and the possible mechanism of electric-physiological changes. Standard microelectrode technique was used to record AP in isolated rat myocardium, and whole cell patch clamp technique was used to record the human Kv1.5 (hKv1.5) channel currents in HEK293 cells. The effects of different concentrations of ethanol (6.25, 12.5, 25.0, 50.0, 100.0 and 200.0 mmol/L) on AP parameters in rat atrium and papillary and Kv1.5 channel currents in HEK293 cells were analyzed. The results showed that in isolated atrium, action potential amplitude (APA), action potential duration (APD), action potential duration of 50% repolarization (APD(50)) and action potential duration of 90% repolarization (APD(90)) were not affected by 6.25 and 12.5 mmol/L ethanol, while APD, APD(50) and APD(90) were prolonged significantly by 25.0-200.0 mmol/L ethanol (P < 0.05 or P < 0.01), and APA was reduced with 100.0 and 200.0 mmol/L ethanol (P < 0.05 or P < 0.01). In isolated papillary, APA, APD, APD(50) and APD(90) were not affected by 6.25-25.0 mmol/L ethanol, while APD, APD(50) and APD(90) were prolonged significantly with 50.0-200.0 mmol/L ethanol (P < 0.05 or P < 0.01), and APA was reduced with 200.0 mmol/L ethanol (P < 0.05). The Kv1.5 channel currents were inhibited by ethanol in a concentration dependent manner in HEK293 cells. These findings suggest that 6.25 and 12.5 mmol/L ethanol produce no effects on AP parameters, and 50.0-200.0 mmol/L ethanol prolong APD significantly in isolated rat atrium and papillary. The prolonged effect on APD in isolated myocardium may be due to the inhibition of the Kv1.5 channel currents.

Objective To investigate the behavioral characteristics of men who have sex with men(MSM)with sadomasochism associated bleeding and to analyze the relationship with HIV/AIDS high risk behavior.Methods Using modified snowball sampling methods(target sampling methods)to carry out a cross-sectional study on persons with behavior of sadomasochism that associated with bleeding in MSM,using a valid questionnaire.Another control group without the related behavior was set up.SPSS 13.0 was used.Results People practicing sadomasochism associated with bleeding had higher percentage in the following indicators:number of accumulated same gender sexual partners (median=20),anal intercourse(median=10),oral intercourse(median=10),hand intercourse (median=15)with same gender sexual partners,number of same gender sexual partners in the previous six months(median=4),numbers of anal intercourse(median=3),hand intercourse(median=3),were more than in the control group.People with sadomasochism associated bleeding had higher rates in the following behaviors:condom was ever broken or slipped in the previous six months (22.6%),suffering from disease of sexual transmitted infections(28.0%),involving in group-sex intercourse(34.8%),having sex with same sex strangers at the place for MSM in the previous six months(62.2%),ever having initiative or passive behavior of oral-anal sex(64.0%),fist-sex(18.9%),finger-sex(66.7%),bleeding during sexual intercourse(58.3%),first coition object was pupil (33.8%),having strong suicide attempts(33.3%)and suicide attempt(23.6%)etc.were more than in the control group.Conclusion MSM who had the behavior of sadomasochism which associated with bleeding had the higher percentage of HIV/AIDS high risk behaviors than the persons without those behaviors.The latter group called for special concern on interventions.
