OBJECTIVE:To observe the efficacy and safety of Bifid triple viable capsule in the treatment of ulcerative colitis (UC). METHODS:94 patients with UC were randomly divided into control group and research group. Control groups was given nutrition support,light diet and 5-amino salicylic acid and other conventional treatment;research group was additionally given 420 mg Bifid triple viable capsule,3 times aday. Treatment course for both group was 8 weeks. The clinical efficacy,and serum D-lac-tic acid,diamine oxidase(DAO)levels before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in research group was significantly higher than control group,the difference was statistically sig-nificant(P<0.05);after treatment,serum D-lactic acid,DAO levels in 2 groups were significantly lower than before,and re-search group was lower than control group,the differences were statistically significant(P<0.05 or P<0.01);and there was no sig-nificant difference in the incidence of adverse reactions(P>0.05). CONCLUSIONS:Based on the conventional treatment,both the efficacy and safety of Bifid triple viable capsule are good in the treatment of UC.

AIM: To observe the effects of dexamethasone and interleukin-10 (IL-10) on the release of proinflammatory cytokines, tumor necrosis factor-?(TNF-?), IL-6 and activation of transcriptional factors, nuclear factor-?B(NF-?B), activator protein-1 (AP-1) and cAMP response element binding protein (CREB) in cultrued human peripheral blood mononuclear cells (hPBMC). METHODS: The hPBMC were divided into control group, lipopolysaccharide (LPS) stimulated group, dexamethasone and IL-10 treated group. The contents of TNF-? and IL-6 in supernatant were mensured by ELISA. The activity of NF-?B, AP-1 and CREB of nuclear abstract were analyzed by electrophoretic morbility shift assay (EMSA). RESULTS: The content of TNF-? was significantly increased 1 hour after LPS stimulation, and it was significantly inhibition by dexamethasone and IL-10. The contents of IL-6 and IL-10 were significantly increased after LPS stimulation for 12 hours. The production of IL-6 was still inhibited by dexamethasone and IL-10, but the production of IL-10 was not affected by dexamethasone. The activities of NF-?B, AP-1 and CREB were significantly increased 1 hour after LPS stimulation. Dexamethasone and IL-10 significantly ihibited their activities, but the effects of dexamethasone was stronger than that of IL-10. CONCLUSIONS: LPS induces the release of several pro and anti- inflammatory cytokines and induces the activation of several transcriptional factors in hPBMC. Dexamethasone and IL-10 can inhibite the production of proinflammatory cytokines TNF-?, IL-6 and the activation of NF-?B, AP-1 and CREB. Dexamthasone has more significant inhibitory effect on AP-1 and CREB than IL-10.

AIM: In order to explore the role of activator protein-1 (AP-1) and cAMP response element binding protein (CREB) in acute lung injury and anti-inflammatory mechanism of glucocorticoid. METHODS: Using the acute lung injury (ALI) model of rats by intravenous lipopolysaccharide (LPS, 5 mg/kg), the activities of AP-1 and CREB by electrophoretic mobility shift assay (EMSA) in lung tissue and effects of dexamethasone on the activities were observed. RESULTS: After injection of LPS, the peak activity of AP-1 was observed at 2 hours and it returned to normal in 12 hours. CREB peak activity was at 1 hours but it did not return to normal in 12 hours. Dexamethasone significantly inhibited the activities of AP-1 and CREB. CONCLUSIONS: AP-1 and CREB may play important roles in ALI in rats. One of the important anti-inflammatory mechanisms of glucocorticoid is its transcription al modification. [

Objectives To evaluate the impact of virtual hepatectomy and computer-assisted risk analysis on surgical planning and intraoperative strategy for major hepatectomy.Methods Twentytwo consecutive patients (17 males and 5 females) were admitted to the hospital from January to December in 2010 for complicated major hepatectomy.CT scanning was performed with 64-MSCT.All the data of imaging were transferred to the Myrian(R) XP-Liver system (IntrasenseR,France).The following steps were undertaken by a radiologist and a surgeon majoring in liver surgery: step 1,image analysis and 3-D reconstruction; step 2,virtual resection and liver volumetry; step 3,computer-assisted risk analysis for hepatic dysfunction,followed by adjustment of the operative planning.Results The three-dimensional reconstruction models of the liver by the Myrian(R) XP-Liver system were visualized.The ideal simulation effect was achieved comparing the virtual imaging with the actual operation.Of the 22 patients who underwent complicated major hepatectomy,complete tumor removal (R0 resection) was achieved in 20 patients.There were 2 patients who received a R1 resection as microscopic tumor cells were found at the cutting margin of the right portal vein and bile duct.No patient died during the hospital stay.After computer-assisted risk analysis,the operative planning and surgical strategies were changed in 6 patients.Conclusions The application of the hepatic three-dimensional reconstruction and virtual hepatectomy using the Myrian(R) XP-Liver system provided important preoperative data for good preoperative planning and intraoperative strategy in complex hepatectomy.

Objective: To understand changes of physical fitness, among college freshmen in one college in Xi an from 2005 to 2018. Methods: Body mass index (BMI), vital lung capacity and cardiorespiratory endurance test data from 47 047 freshmen from 2005 to 2018 were included and analyzed. BMI, vital lung capacity, and cardiorespiratory endurance were classified according to the National Student Physical Fitness and Health Standard. Descriptive statistics, t test was used in the data analysis. Results: Mean BMI, vital lung capacity and cardiorespiratory endurance for male and female were (21.69±3.26) (20.88±2.65) kg/m 2, (4 189.87±788.57) (2 815.06±572.07) mL, (246.17±24.09) (239.97±20.23) s, respectively, all of which had significant statistical differences (t=29.48, 218.87, 28.70, P<0.05). Physical fitness indicators showed significant differences over the years (F=104.82, 185.43, 40 891.99, P<0.05). Mean BMI and vital lung capacity in male and female freshmen showed nonlinear increase trend across the past 14 years, while endurance showed a "V"shaped change with a significant inflection point in the year of 2009. Conclusion From 2005 to 2018, BMI and vital lung capacity showed an upward trend, and cardiorespiratory endurance quality continued to decline since 2009 among college freshmen.

OBJECTIVETo study the causes of poorer antiviral response to neutralizing anti-interferon-alpha antibodies (NA) in male chronic hepatitis B patients treated with recombinant interferon-alpha (rIFN-alpha).

METHODSTwo hundred sixty-nine patients (198 males and 71 females) with histologically proven chronic hepatitis B were treated with 5 MU recombinant interferon-alpha 1b (rIFN-alpha 1b) subcutaneously thrice weekly for 6-37 (median 10.0) months. For each patient, serum HBV DNA levels were detected with fluorescent-quantitative PCR, HBeAg with enzymoimmunoassay, and NA with an antiviral neutralizing biological assay during therapy.

RESULTSNA was found in 70 (35.4%) of the 198 males and in 15 (21.1%) of the 71 females during treatment (x2 = 4.894, P = 0.027). At the end of treatment combined-response was achieved in 21 (24.7%) of the 85 NA-positive patients and in 100 (54.3%) of the 184 NA-negative cases (x2 = 20.642). Stratification analysis by NA showed that combined-response rate was significantly lower in males than in females (18.6%, 13/70 vs. 53.3%, 8/15, x2 = 8.024) among NA-positive patients while it was similar in males and in females (50.8%, 65/128, vs. 62.5%, 35/56, x2 = 2.156) among NA-negative patients. In stratification analysis by gender, it was significantly lower in NA-positive patients than in NA-negative ones (18.6%, 13/70 vs. 53.3%, 8/15, x2 = 8.024) among males but there was no significant difference between combined-response rates among females.

CONCLUSIONThe poorer antiviral response to recombinant interferon-alpha in male chronic hepatitis B patients than in female patients is related to the neutralizing anti-interferon antibodies.

OBJECTIVETo improve the diagnostic ability of routine laboratory items in liver diseases associated with viral hepatitis through constructing assessment models consisting of these items.

METHODS(1) Assessment of routine items and formulation of models. Data of 447 patients seen between May 1997 and August 2003 were collected as the training set and serum specimens of 213 patients taken between June 2004 and March 2005 were examined and used as the validation set. Eleven items (TP, ALB, TBIL, DBIL, ALT, AST, ALP, GGT, TBA, LDH, CHE) were examined with an automated biochemical analyzer. Logistic regression was applied to construct the model for discriminating between chronic hepatitis and liver cirrhosis. The diagnostic value of items and models was assessed by the area under the receiver-operating characteristic (ROC) curve.

RESULTSThe model to discrimination between chronic hepatitis and liver cirrhosis consists of five items (CHE, DBIL, ALB, ALT, GLO). The AUCs of model were 0.87 in the training set and 0.83 in validation set, respectively.

CONCLUSION(1) The model consisting of CHE, DBIL, ALB, ALT, GLO improves the diagnostic value of routine laboratory items in discriminating chronic hepatitis from liver cirrhosis.

Objective: To observe the safety and effects of application of analgesic and sedative drugs in severely burned patients during shock stage. Methods: One hundred and eighty patients with severe burns, conforming to the study criteria, were admitted to our unit from August 2014 to August 2016. Patients were divided into analgesia and sedation group and control group according to whether receiving analgesic and sedative treatment or not, with 90 cases in each group. Patients in control group received conventional treatment, while those in analgesia and sedation group received analgesic and sedative treatment for 24 hours besides conventional treatment. Before and at drug administration hour 2, 8, 16, and 24, pain degree of patients in two groups was scored by visual analogue scale (VAS). At drug administration hour 2, 8, 16, and 24, sedation degree of patients in two groups was scored by richmond agitation sedation scale, and the success rate of sedation was calculated. Mental state of patients within 24 hours of drug administration was observed, while pulse oxygen saturation (SpO₂), respiratory rate, heart rate, and blood pressure were observed and dynamically evaluated every 2 hours. The accidental extubation, tachycardia, hypertension, hypoxia, bradycardia, hypotension, urinary retention, and respiratory depression of patients within 24 hours of drug administration were monitored and recorded. Data were processed with analysis of variance for repeated measurement, one-way analysis of variance, t test, chi-square test, Wilcoxon rank sum test, and Fisher′s exact probability test. Results: (1) The VAS scores of patients in two groups were close before drug administration (t=0.675, P>0.05). The VAS scores of patients in analgesia and sedation group at drug administration hour 2, 8, 16, and 24 were (3.8±0.4), (3.9±0.6), (3.9±0.5), and (3.9±0.9) points, respectively, significantly lower than (6.0±0.9), (6.0±1.2), (6.2±0.6), and (6.3±0.4) points in control group (t=0.785, 0.730, 0.805, 0.895, P<0.05). The success rate of sedation of patients in analgesia and sedation group at drug administration hour 2, 8, 16, and 24 were 91.1% (82/90), 86.7% (78/90), 93.3% (84/90), and 90.0% (81/90), respectively, significantly higher than 7.8% (7/90), 6.7% (6/90), 14.4% (13/90), and 5.6% (5/90) in control group (Z=8.035, 7.946, 8.129, 8.014, P<0.05). (2) The respiratory rate of patients in analgesia and sedation group at drug administration hour 8, 16, and 24 were (15.78±0.69), (16.08±0.59), and (16.21±0.20) times per minute, and the heart rate were (87±9), (83±7), and (76±9) times per minute, respectively, significantly lower than (16.80±0.81), (17.09±0.50), and (17.02±0.61) times per minute and (89±8), (86±7), and (85±6) times per minute in control group (t=7.655, 7.022, 6.536, -6.931, -7.053, -10.196, P<0.01). There were no statistically significant difference in SpO₂, systolic blood pressure, and diastolic blood pressure before and at drug administration hour 2, 8, 16, and 24 between the two groups (t=3.417, -2.894, -6.501, -3.719, -4.573, 2.336, 3.315, 0.942, -1.583, 1.907, 1.147, -0.968, 0.931, -1.682, 1.076, P>0.05). (3) The rates of respiratory depression, hypoxia, bradycardia, urinary retention, and hypotension of patients in the two groups were close (χ²=0.310, P>0.05). The rates of hypertension, accidental extubation, and tachycardia of patients in analgesia and sedation group were significantly lower than those in control group (χ²=16.364, 5.143, 73.309, P<0.05 or P<0.01). Conclusions Proper application of analgesic and sedative drugs in severely burned patients during shock stage has good clinical effect with low incidence rates of complications.
