Objective To evaluate the effects of penehyclidine hydrochloride (PHC) on the expression of Toll like receptor-4 (TLR4) and nuclear factor kappa B (NF-κcB) in a rat model of sepsis-induced acute lung injury (ALI).Methods Seventy-two adult male Sprague-Dawley rats,weighing 180-220 g,were randomly divided into 3 groups (n =24 each) using a random number table:shame operation group (group S),ALI group and PHC group.Sepsis-induced ALl was induced by cecal ligation and puncture in anesthetized rats.In group PHC,PHC 0.45 mg/kg was intramuscularly injected immediately after cecal ligation and puncture.At 6,12,24 and 36 h after ligation,the broncho-alveolar lavage fluid (BALF) was collected for detection of TNF-α and IL-6 concentrations and the lungs were removed for determination of the expression of TLR4 (using RT-PCR and Western blot) and NF-κBp65 (using Western blot) in lung tissues and for microscopic examination.The pathological changes of lungs were scored.The wet to dry lung weight (W/D) ratio was calculated and the activity of myeloperoxidase (MPO) in lung tissues was measured.Results As compared with S group,the IL-6 concentrations in BALF at 6,12 and 24 h after ligation,TNF-α concentration in BALF at 6 and 12 h after ligation,and the expression of TLR4 and NF-κBp65,pathological scores,W/D ratio and MPO activity at each time point were significantly increased in ALI group (P ＜ 0.05).Compared with ALI group,the TNF-α concentration in BALF at 6 and 12 h after ligation,and IL-6 concentrations in BALF,the expression of TLR4 and NF-κBp65,pathological scores,W/D ratio and MPO activity at each time point were significantly decreased in group PHC (P ＜ 0.05).Conclusion PHC inhibits NF-κB activation and decreases inflammatory responses through blocking TLR4 expression in lung tissues,thus attenuating sepsis-induced ALI in rats.

Objective To explore the factors affecting urinary arsenic methylated metabolites in population exposed to elevated arsenic through drinking water.Methods Residents,including 73 males and 72 females,in a endemic village located in Inner Mongolia Autonomous Region where the concentration of arsenic in drinking water was 0.167 mg/L,were included in the study; moming urine samples were collected; individual height and weight were measured which could be used to calculate body mass index(BM庆) ; and smoking and drinking habit was investigated by a questionnaire survey.Urinary concentrations of inorganic arsenic (iAs),monomethylarsenic acid(MMA) and dimethylarsenic acid(DMA) were determined using high performance liquid chromatography hydride generation atomic fluorescence spectrometry (HPLC-HG-AFC).Total arsenic (T-As) level was calculated by the sum of iAs,MMA and DMA; iAs％,MMA％ and DMA％ was calculated based on iAs/T-As,MMA/T-As and DMA/T-As.One methylation ratio(PMI) and dimethyl rate(SMI) were calculated by MMA/iAs and DMA/MMA.Results SMI level of female was significantly higher than that of male [median (M) =4.18,3.38,x2 =11.219,P ＜ 0.05] ; MMA％ of female was significantly lower than that of male(M =15.1 9,18.06,x2 =9.272,P ＜ 0.05) ; DMA％ of female was significantly higher than that of male (M =65.61,59.47,x2 =11.728,P ＜ 0.05).Various forms of arsenic indexes were not affected by smoking,alcohol consumption and BMI(P ＞ 0.05).BMI was negatively correlated with MMA％,with correlation coefficient (r)-0.17 (P ＜ 0.05).Conclusions Under the same condition of arsenic exposure,arsenic methylation capacity of women is higher than that of men.Lower BMI is significantly associated with higher methylation capability of arsenic,but this correlation may be affected by other confounding factors.

To prevent surgical risk, improve the quality of operation, and evaluate surgical doctors scientifically, it provides management experience and references.

Objective To evaluate the safety of laparoscopic resection for giant abdominal benign mass.Methods Six cases of giant abdominal benign mass(8～25 in diameter)underwent laparoscopic exploration and resection under general anesthesia from July 2005 to March 2006.Results The laparoscopic resection was accomplished in all the 6 cases.The operation time was 75～220 min(mean,135 min),the intraoperative hemorrhage volume was 20～100 ml(mean,55 ml),the duration for abdominal drainage was 1～3 d(mean,2 d),and the postoperative hospital stay,2～7 d(mean,4.3 d).There was no complications such as intestinal injury,postoperative bleeding,or abdominal infection.Follow-up visits for 1～9 months(mean,6.5 months)found no recurrence.Conclusions Laparoscopic resection of giant abdominal benign mass is a feasible and safe minimally invasive technique.

Objective:To investigate the prevalence of Cluster-B personality disorders in university students. Methods: 1. Personality Diagnostic Questionnaire (PDQ+4) was administered to a sample which consisted of 3140 university students to screen personality disorder subjects. Cluster-B personality disorder subjects were finally diagnosed by conducting bland semi structured interview using Personality Disorder Interview-IV (PDI-IV) four to six weeks after the first administration. Results: The total prevalence of Cluster-B personality disorders among 3140 subjects of university students was 1.21% with 38 subjects met the diagnostic criteria of Cluster-B personality disorders. One female subject met the criteria of Antisocial Personality Disorder (APD), 21 Borderline Personality Disorder (BPD), 20 Narcissistic Personality Disorder (NPD), and 8 Histrionic Personality Disorder (HPD). The prevalence of BPD, NPD and HPD were 0.67%, 0.64% and 0.25% respectively. Ten subjects met the criteria of more than one personality disorder; the comorbidity rate was 26.3%. Conclusion: The prevalence of Cluster-B personality disorder in university students is lower than in general population reported by foreign researchers.

OBJECTIVE To explore the changes in foot fungus mobility and its drug resistance for further etiology investigation and clinical treatment. METHODS Sabourand′s agar culture medium was used to culture fungi, ID identification strip was employed to identify the fungi and drug sensitive test was performed by disk diffusion test. RESULTS The incidence of Trichophyton rubrum infection was the highest (79.1%). The isolated fungi were relatively sensitive to amphotericin B (AMB, 98.9%) and itraconazole (ITC, 98.0%), and resistant to 5-fluorocytosine (5-FC, 22.1%). CONCLUSIONS Detection technique of fungal infection should be improved and anti-fungal medicine should be used reasonably according to the results of drug sensitive test so that the fungal infection, especially fungi-resistant infection could be reduced.

OBJECTIVE A new piezoelectric aptamer biosensor is developed for determination of IgE. The energy converters are 10MHz AT-cut quartz crystals with gold-coated electrodes. The anti-IgE aptamers are immobilized onto the surfaces of crystals gold electrodes by biotin-avidin method.
