Objective To investigate the impacts of Xuebijing injection on systemic inflammatory response and immune function of patients with acute exacerbation of severe chronic obstructive pulmonary disease (AECOPD). Methods A prospective randomized controlled trial (RCT) was conducted. Forty patients with severe AECOPD were divided into control group and Xuebijing group in accordance with the random number table, each group 20 cases. Both groups were treated by routine conventional basic therapy of severe AECOPD including anti-infection, phlegm-expelling formula, bronchodilators and mechanical ventilation, etc, while in Xuebijing group, intravenous drip of Xuebijing (100 mg, twice a day for 5 days) was additionally used. The changes of data of arterial blood gas analysis, blood routine examination, C-reactive protein (CRP), procalcitonin (PCT), immune function, and acute physiology and chronic health evaluation system Ⅱ (APACHE Ⅱ) score before and after therapy were observed and compared between the two groups. The length of stay in hospital, duration of mechanical ventilation, and prognosis were also compared between the two groups. Besides, according to the difference in APACHE Ⅱ score, all the patients were divided into APACHEⅡscore≥15 score group (18 cases) and APACHEⅡscore<15 score group (22 cases), and the immune function were compared between the two groups. Results ①The immune function was descended and disordered in patients with severe AECOPD. Compared with the < 15 score group, the expressions of CD45+, CD3+, CD4+, CD4+/CD8+ ratio, B-lymphocyte, natural killer cell (NK cell) in ≥ 15 score group were significantly lowered [CD45+(×106/L):663.92±100.61 vs. 1 289.92±169.38, CD3+(×106/L):342.05±108.93 vs. 882.37±172.56, CD4+(×106/L):205.96±63.97 vs. 486.24±108.64, CD4+/CD8+ratio:0.76±0.49 vs. 1.32±0.57, B-lymphocyte (×106/L):124.77±32.72 vs. 166.06±48.02, NK cells (×106/L): 186.47±39.57 vs. 243.51±44.72, all P < 0.05]. There was no statistically significant difference in the expression of CD8+ between the ≥ 15 score group and < 15 score group (P > 0.05). ② Compared with those before therapy, the pH value, oxygenation index, arterial partial pressure of carbon dioxide (PaCO2), white blood cell count (WBC), CRP, PCT were significantly improved after therapy in both control and Xuebijing groups. Compared with those in the control group, WBC, CRP, PCT were significantly lowered in Xuebijing group [WBC (×109/L): 10.29±3.83 vs. 12.69±3.42, CRP (mg/L): 9.06±4.19 vs. 15.26±4.22, PCT (ng/L): 0.18±0.21 vs. 0.42±0.24, all P < 0.05]. There were no statistically significant differences in pH value, oxygenation index and PaCO2 between two groups (all P>0.05). The degrees of improvement of CD45+, CD3+, CD4+, CD8+ and CD4+/CD8+ ratio were more remarkable in Xuebijing group after treatment than those in control group [CD45+ (×106/L): 1 079.38±153.86 vs. 1 015.63±157.11, CD3+ (×106/L): 652.05±100.05 vs. 596.81±106.85, CD4+ (×106/L): 358.92±67.53 vs. 329.99±72.61, CD8+ (×106/L): 205.73±35.19 vs. 230.41±39.74, CD4+/CD8+ratio: 2.16±0.63 vs. 1.52±0.54, all P < 0.05]. The B-lymphocyte and NK cell before treatment and after treatment showed no statistical significant differences between the two groups (all P > 0.05). Compared with the control group, the duration of mechanical ventilation (hours: 56.25±22.87 vs. 69.45±26.59) and the length of stay in hospital (days: 11.00±0.74 vs. 14.00±2.06) were shortened, and APACHE Ⅱ score was significantly lowered in Xuebijing group (8.21±2.97 vs. 12.08±3.12, P < 0.05). The numbers of multiple organ failure and dead patients in Xuebijing group were less than those of control group, but no statistical significant differences were found (both P > 0.05). Conclusion Xuebijing injection for treatment of patients with severe AECOPD can ameliorate inflammatory response, improve immune function, shorten the duration of mechanical ventilation and the length of stay in hospital, and decrease the risk of death.

Abnormal methylation of the tumor-related genes is frequently found in the development of gastric cancer.Cancer cells exhibit two opposing methylation abnormalities:genome-wide hypomethylation and certain tumor suppressor gene hypermethylation.Furthermore,it seems that the level of DNA methylation is closely associated with the prognosis of gastric cancer.Recently,a great deal of research has been conducted to reveal the corelation of DNA methylation and gastric cancer.

Fire-dragon moxibustion is a modified moxibustion method based on the traditional moxibustion therapy. It’s more easy-to-operate, has higher security, and is more significant in supplementing yang qi. Via extensive and intensive hot stimulation, fire-dragon moxibustion can activate yang qi inside human body, regulate Zang-fu organs, modulate immune function, and finally achieve the goal of preventing and treating diseases.

Diagnostics Teaching is the important transition period from the completion of basic medical knowledge to clinic practice.In the period,we should not only pay attention to medical knowledge and clinic techniques,but also emphasize humane spirit education,which is the basic principle of medical science,the intrinsic request of medical mode and especially the urgent request of relieving confliction between doctors and patients and of reconstructing harmonious society.At present,the present situation of humane spirit education of the interns is not ideal.This article tries to analyze the associated reason and discusses the countermeasures.

Chemically Glitazones belong to Thi-azolidinediones. Glitazones enhance the sensitivity of target tissues to insulin and reduce insulin resistance. They, celled insulin sensitizers, are a new class of oral hypoglycemics. These agents can't reduce the blood glucose values either in normal animal or I type diabetic animal, but do have good effects on spontaneous diabetic animal and artificial insulin resistance animal. The research on insulin resistance needs euglycemic clamp for determination and the main index of assessing euglycemicclamp is glucose infusion rate in stable state. So far, the hypoglycemic mechanism of glitazones has been believed to be associated with PPARs(Peroxi-some Proliferator-Activated Receptors ). Gli-taziones act on PPAR Y, play an indirect part in insulin signal transduction and enhance the action of insulin. However, the precise mechanism still remains unknown.

The arteries and/or the veins of 30 human stomaches (11 adults,19 infants)were perfused with coloured gelatin or methylmethacrylate.The specimens were madeinto section and spreading preparation,and cast,and studied under LM and SEM.The main results were as follows:1.Mucosal arterioles divided into 2kinds of branches,i.e.luminal arteriole and glandular arteriole,and hadanastomosis.Luminal capillaries which lay in lamina propria around gastric pitoriginated from the luminal arterioles and from the glandular capillaries.2.Mucosalcapillaries drained into mucosal venule at 3 levels,viz.the luminal surface,theglandular neck and the glandular base.There were 2 kinds of venular anastomosis:the anastomosis between the straight mucosal venulae at the level of the glandularneck or the base of the gastric pit,and the basal venular plexus which lay betweenthe muscularis mucosae and the base of gastric gland.3.Mucosal blood vesselsobserved on transverse section might be divided into 3 parts:base-body,neck-body,and gastric pit.In neck-body part the density of capillaries is the highest.4.Flat,round or elliptic impressions of endothelial nuclei can be seen on the cast ofmucosal venule under SEM.It was interesting that a pit was noted at the center ofeach impre-ssion.The importance of mucosal blood vessels in the mucosa is forprotection from invasion and damage effected by luminal contents.

OBJECTIVE:To investigate therapeutic efficacy of bifidobacteria triple viable bacteria combined with infliximab in the treatment of moderate and severe ulcerative colitis(UC),and its effects on immune function. METHODS:Seventy-two UC pa-tients were selected from gastroenterology department of the First Affiliated Hospital of Chongqing Medical University during Jun. 2009 to Jan. 2015. They was divided into single group and combination group according to therapy plan,with 36 cases in each group. Single group was given infliximab 5 mg/kg,ivgtt,on 0,2nd,6th,8th week. Combination group was additionally given bi-fidobacteria triple viable bacteria 420 mg,tid. Both groups were treated for consercutive 2 months. Clinical efficacies were com-pared between 2 groups as well as the levels of humoral immunity and T cell function. The occurrence of ADR was observed in 2 groups. RESULTS:Clinical response rate of combination group was 86.11%,which was significantly higher than 52.78% of single group,with statistical significance (P<0.05). Before treatment,there was no statistical significance in humoral immunity and T cell function between 2 groups(P>0.05). After treatment,the levels of CD4+ and CD4+/CD8+ were significantly increased in both 2 groups,while the levels of CD8+,Th1 and Th2 were significantly decreased;the combination group was significantly better than the control group,with statistical significance (P<0.05);there was no statistical significance in CD3+ between 2 groups before and after treatment(P>0.05). After treatment,the levels of IgA and IgG were increased significantly in 2 groups,and the level of C3 was decreased significantly;the combination group was significantly better than the control group,with statistical significance (P<0.05);there was no statistical significance in IgM content and C4 level between 2 groups before and after treatment (P>0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Bifidobacteria triple viable bacteria combined with infliximab shows significant therapeutic efficacy in the treatment of moderate and severe UC, and can significantly improve humoral immunity function and the recovery of T cell level,with good safety.
