Objective To observe the effects of Qingfei Chengqi decoction on lung tissue cell apoptosis and its associated protein,tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)of lung tissues in rats with severe intra-peritoneal infection(SII). Methods Thirty male Wistar rats were randomly divided into three groups:sham operation group,model group and traditional Chinese medicine(TCM)group(each n=10). Simulating clinical pathophysiological process of digestive tract perforation,the rat model of SII was reproduced by injecting E. coli intraperitoneally. The TCM group was treated by gavage with Qingfei Chengqi decoction one day in advance of the study,3 times per day,once 2 mL. The same amount of nutrient broth which contained 10%barium sulfate(BaSO4) to replace the bacteria solution was injected into the sham operation group. Six hours after model establishment,all rats were killed and lung tissues were harvested for pathohistological evaluation and for the determination of apoptosis rate with TdT-mediated dUTP nick-end labeling(TUNEL)method,of Bax,Bcl-2 protein expression with Western Blot method,and of the level of TNF-α,IL-6 with enzyme-linked immunosorbent assay(ELISA)method,and the pathological changes of lung tissues were observed under the light and electron microscopes. Results Compared with sham operation group,the apoptosis rate〔(12.7±5.4)%vs. 0〕,the expression of Bax protein〔absorbance(A)value:8 416.89±875.16 vs. 6 654.09±1 130.18〕,the level of TNF-α(ng/L:3 132.56±457.96 vs. 1 948.55±269.32), the level of IL-6(ng/L:75.14±1.63 vs. 31.17±0.81)of lung tissues were significantly increased(all P<0.05), meanwhile Bcl-2 protein expression decreased observably(A value:7 490.59±200.34 vs. 12 289.02±535.93,P<0.05)in model group induced by SII. After treatment with TCM,apoptosis rate〔(7.9±0.3)%〕,the expression of Bax protein(A value:7 619.50±999.30),the level of TNF-α(ng/L:3 114.34±454.32)and IL-6(ng/L:52.46±0.96) of lung tissues were decreased and Bcl-2 protein expression(A value:11 155.07±1 018.87)increased(all P<0.05) compared with model group. General observation:the color of lung tissues was uniform in sham operation group;the lung tissues of model group swelled obviously,and parts of lung tissues had patches of ecchymosis and hemorrhage. The light microscope showed:the pulmonary vessels,the alveolar interstitium,alveolar epithelium and lobular interstitium of sham operation group were all normal,while in the model group,the pulmonary interstitium was edematous and hemorrhagic,and in the alveolar cavities there was infiltration of inflammatory cells. Under the electron microscope, the lung tissue type Ⅱ alveolar epithelial cells of model group were increased,and they had morphological changes in various degrees,such as cell shrinkage and change becoming round,and cell nucleus presenting irregular in shape. After treatment with TCM,the above pathological changes were all alleviated compared with those in the model group. Conclusions Qingfei Chengqi decoction can ameliorate the SII leading to acute lung injury,and reduce the cell apoptosis rate of lung tissues in SII rats. Its mechanism may be related to the intervention of above TCM which can lower the levels of inflammatory media and elevate the protein expression of Bcl-2.

Objective To investigate the components of mesenteric lymph of the rats with severe intraperitoneal infection,and inquire into the effect of intestinal lymphatic pathway in severe intraperitoneal infection.Methods Twenty-four male Wistar rats were randomly divided into two groups according to random number table method,namely model group and sham group with 12 rats in each group.The rat model of severe intraperitoneal infection was reproduced by injecting artificial gastric juice and E.coli intraperitoneally.Mesenteric lymph in both groups was collected 4 hours after the reproduction of the model,and white blood cells were counted and classified.The levels of endotoxin,alkaline phosphatase (AKP),lactate dehydrogenase (LDH),creatine kinase (CK),glutamine transferase (GST),protein and cytokines of mesenteric lymph were determined.Results Compared with the sham group,there was an increase in the neutrophil ratio in mesenteric lymph (0.167 ± 0.004 vs.0.610 ± 0.006,t=33.520,P＜0.001),however the percentage of both macrophages (0.009 ± 0.001 vs.0.020 ± 0.004,t=-6.677,P＜0.001) and lymphocytes (0.824 ± 0.005 vs.0.921 ± 0.004,t=-31.471,P＜0.001) was decreased in model group.Compared with sham group,the levels ofendotoxin (kEU/L:0.346 ±0.022 vs.0.186 ±0.001,t=18.103,P＜0.001),AKP [U (king unit):13.97 ± 5.55 vs.3.76 ± 0.18,t=4.503,P=0.006],LDH (U/L:2 827.45 ± 1 940.32 vs.712.68 ± 14.09,t=2.670,P=0.044),CK (kU/L:2.19 ± 1.21 vs.0.70 ± 0.01,t=3.035,P=0.029),GST (kU/L:12.33 ± 6.53 vs.1.36 ± 0.39,t=4.105,P=0.009) were all significantly elevated.The concentration of protein (g/L:4.40 ± 0.48 vs.2.84 ± 0.16,t=6.882,P=0.001),tumor necrosis factor-α [TNF-α (ng/L):499.39 ±76.36 vs.180.90 ± 70.98,t=7.483,P＜0.001],interleukin-6 [IL-6 (μg/L):13.74 ± 0.78 vs.-0.07 ± 0.07,t=52.972,P＜0.001],intercellular adhesion molecule-1 [ICAM-1 (ng/L):2 754.19 ±221.48 vs.1 362.85 ±393.43,t=6.891,P＜0.001] and monocyte chemo-attractant protein-1 [MCP-1 (μg/L):28.23 ± 1.77 vs.24.87 ± 1.15,t=3.561,P=0.007] and high mobility group protein-1 [HMGB-1 (ng/L):1 392.78 ± 572.42 vs.564.17 ± 21.32,t=3.543,P=0.016] in mesenteric lymph in model group were significantly higher than those in sham group.Conclusion Intestinal lymphatic pathway maybe the early pathway for the production of remote organ injury caused by severe intraperitoneal infection.

Objective To evaluate the possibility of slow and rapid liquid nutrient loading test (LNLT) in the proximal gastric function assessment according to the results of gastric barostat testing.Methods From April to August in 2013,20 healthy volunteer were selected.The sensitivity of gastric,basic abdominal pressure,gastric sensing threshold,gastric discomfort and pain thresholds were examined by barostat.The average gastric volume after fasting was tested by barostat,which reflected gastric accommodation.And then 200 mL liquild meal was taken in five minutes by the volunteers.The difference value between the maximum gastric volume in 60 minutes after taking the meal minus the average gastric volume after fasting was used to evaluate the proximal gastric adapted diastolic function.In LNLT,volunteers drank 100 mL/min and 15 mL/min (rapid and slow) liquid meal.The threshold value of drinking volume,satiety drinking volume and maximum drinking volume were determined.Pearson correlation analyses were performed in the results of fast and slow LNLT,correlation between LNLT and sensitivity of gastric,gastric adapted diastolic function tested by barostat.Results The basic abdominal pressure,gastric sensing threshold,gastric discomfort and pain thresholds,gastric volume after fasting,maximum gastric volume and adapted diastolic volume was (6.8±1.2) mmHg (1 mmHg=0.133 kPa),(2.7±1.9) mmHg,(5.2±2.0) mmHg,(7.3-±-2.1) mmHg,(188.7-±-80.0) mL,(505.2±133.7) mL and (316.5±87.7) mL,respectively.The maximum gastric volume after the meal was at (9.8±3.3) min after meal.In rapid LNLT,the threshold value of drinking volume,satiety drinking volume and maximum drinking volume of volunteers was (209-±-96),(501±148) and (674±199) mL,respectively,and that in slow LNLT was (107 ± 43),(340 ± 134) and (524 ± 213) mL,respectively,there was correlation between rapid and slow LNLT (r=0.768,0.825 and 0.856,all P＜0.01).The maximum drinking volume of rapid and slow LNLT was at (8.6± 1.2) and (34.9±6.4) minutes after meal.Threshold value of drinking volume in the slow drinking test was positively correlated with the gastric sensing threshold (r=0.714,P＜0.01).Satiety drinking volume in the slow drinking test was correlated with gastric sensing threshold,gastric discomfort and pain thresholds (r=0.599,0.650 and 0.622,all P＜0.01).The proximal gastric adapted diastolic volume was related with slow satiety drinking volume,rapid satiety drinking volume,slow maximum drinking volume and rapid drinking volume (r＝0.543,0.636,0.527 and 0.493,all P＜0.05).Conclusions Threshold value of drinking volume and satiety drinking volume in the slow LNLT is more suitable for evaluating the sensitivity of stomach.Satiety drinking volume in the rapid LNLT is more suitable for the evaluating of gastric adapted diastolic function.

Objective To explore the corrective role of lived combined Bacillus subtilis and Enterococcus faecium enteric-coated capsules on the bacteria overgrowth in small intestinal (SIBO)and assess the efficacy and possible mechanism of it in the treatment of diarrhea predominant irritable bowel syndrome (IBS-D).Methods From May to August 2013,IBS-D patients were collected.Screened by lactulose hydrogen breath test (LHBT),and a total of 60 SIBO positive patients were enrolled in the study and divided into experimental group and control group.Live combined Bacillus subtilis and Enterococcus faecium enteric were given to the experimental group and starch given to the control group,both were capsules,each 250 mg,three times per day,two capsules each time,and the treatment course was four weeks.Before and after administration a questionnaire was conducted in the study objects,including basic information (age,gender,disease type,family history and accompanied diseases) and the severe degree of the symptoms (abdominal pain,bloating,abdominal discomfort,increased frequency of defecation,defecation urgency,defecation endless,defecation hard,bowel and exhaust).Fasting peripheral venous blood was taken from the study individuals before and after administration.The level of interleukin (IL)-1β,IL-6,IL-10,IL-12 and tumor necrosis fator-α(TNF-α) in serum were detected by enzyme linked immunosorbent assay(ELISA).t-test was performed for measurement data comparison between two groups,and chi-square test was for count data comparison.Results Among 60 SIBO positive IBS-D patients,30 patients were in experimental group and 30 in control group.The SIBO negative conversion rate of experimental group and control group was 63.3 ％(19/30) and 30.0％ (9/30),the difference was statistically significant (x2 =6.696,P＜0.05).Before and after administration,in control group there were no significant differences in severe degree scoring of abdominal pain,bloating,abdominal discomfort,increased frequency of defecation,defecation urgency,defecation endless,defecation hard,bowel and exhaust or the level of TNF-α,IL-1β,IL-6,IL-10 and IL-12 (all P＞0.05).In experimental group,before and after administration there were statistically significant differences in severe degree scoring of abdominal floating (2.97 ± 1.45 vs 2.61±1.28),level of IL 1β ((1390.81±103.95) ng/L vs (1209.76±113.26) ng/L)and IL-10/IL-12 (4.94±0.74 vs 5.30±0.43),the differences were statistically significant (t=2.052,5.279 and 2.282,all P＜0.05).There were no signinficant differences in other items (all P＞0.05).Conclusions Lived combined Bacillus subtilis and Enterococcus faecium enteric coated capsules could alleviate the symptoms of abdominal floating.The possible mechanism may related with correcting SIBO,inhibiting low degree of inflammation reaction and regulating the inflammatory cytokines.

Integrated traditional Chinese and Western medicine therapy for pancreatitis has been used since the 1960s.According to the clinical manifestations and traditional Chinese medicine (TCM) syndrome differentiation of pancreatitis,pancreatitis was named true heart pain with cold limbs caused by spleen disease.Syndrome differentiation of acute pancreatitis and treatment with modified Dachaihu decoction achieved good clinical effects.After the 1990s,the research focus of pancreatitis research was shifted to severe acute pancreatitis (SAP).The clinical course of SAP was divided into three phases,and different therapeutic regimens were given.Clinical studies achieved good therapeutic effects in terms of cure rate and fatality rate.After 2000,integrated traditional Chinese and Western medicine therapy for chronic pancreatitis has been promoted systemically,and the cooperation between traditional Chinese medicine,endoscopic techniques,and operative treatment helps to significantly improve pain control,nutritional status,and incidence of complications.

Objective To evaluate the relationship of gastric function of its proximal portion and electrogastrogram in healthy youths with obesity.Methods A total of 35 healthy young volunteers with normal weight participated in the study,including 16 females and 19 males.On the first day,the water load test was performed.On the second day,determination of function of proximal portion of stomach was done using electronic barostat and electrogastrogram.Results Water load test:females were found to consume significantly less water than males(P0.05)between male group and female group in the minimal distention pressure(MDP),initial intragastric pressure(IP)and the maximal tolerance pressure(MP).The initial gastric compliance(IC)in female group was less than that in male group(P0.05).The parameter of EGG:with the intragastric pressure increased,DF in Normal Range(N%)showed decreasing tendency,while bradygastria(B%),tachygastria(T%),instable coefficient of dominant frequency(DFIC)and dominant power(DP)increased.Conclusion The gastric capacity,the parameters of visceral sensitivity and IC are remarkably different between sexes.The gastric electrical activity varies in different states of proximal gastric function.The gastric contraction may be enhanced by an improvement of dominant power(DP).

Objective To investigate the changes of the serum levels of matrix metalloproteinase- 2 (MMP-2) and peripheral blood leukocytes content and its relationship with the severity of cerebral infarction in acute cerebral in-farction(ACI)patients at different altitudes (high, middle and low). Methods One hundred thirty-nine cases and 150 healthy controls were included in the present study. Enzyme linked immunosorbent method was used to detect MMP-2 and WBC levels. Results MMP-2 levels increased as the altitude increased in controls. The MMP-2 in a descending or-der was 1.41±0.39 in Haixi (high altitude), 1.37±0.27 in Xining (middle altitude) and 1.28±0.21 in Sichuan (low altitude) (P<0.05). The serum levels of MMP-2 were significantly increased at 7 d at different altitudes (5.75±1.19, 5.23±1.12 and 4.15 ± 0.97 in low, middle and high altitudes, respectively). The WBC were significantly increased at different alti-tudes (12.93±2.11, 12.11±1.74 and 11.15±1.68 in low, middle and high altitudes, respectively) within 48 h in severe ACI group (P<0.05). MMP-2 levels in different altitudes were positively associated with the infarction size and the degree of neurological deficit, while were negatively correlated with the prognosis. The WBC in large infarction group were positive-ly correlated with the infarct size. Conclusions The levels of MMP-2 and WBC in different altitudes may be helpful in determining the ACI lesion size and the severity of the illness as well as estimating the prognosis.

Objective:To assess the quality of life (QOL) and cognition function in patients with severe obstructive sleep apnea (OSAHS), and to study the relationship between the QOL and severity of OSAHS, excessive daytime sleepiness (EDS),cognition disorders. Methods:Sixty-two patients with OSAHS and 32 non-OSAHS patients (control group) which all diagnosed by polysomnography (PSG) were chosen from The First Hospital of Lanzhou University, and they were assessed by QOL using the Short-Form 36 Health Survey questionnaire (SF-36), by EDS using the Epworth sleepiness scale (ESS), and for cognition disorders by mini-mental state examination (MMSE).The associations between the total score on the SF-36 and the baseline characteristics, PSG parameters, such as ESS score, and MMSE score were examined by simple regression analysis and stepwise multiple regression analysis.Results:The scores of SF-36 and MMSE in OSAHS group were significantly lower than the control group (63.9?14.7/78.8?4.5, 24.6?2.0/27.1?1.3,P
