Conclusion Small intestine epithelium, mucous membrane and submucosa microcirculatary ultrastructral showed obvious changes in PHT canines.

Objective To investigate the effects of esophagogastric intramural anastomosis on preventing reflux esophagitis by restoring the cardiac function after esophagectomy.Methods The clinical data of 66 esophagem or cardiac cancer patients(test group)who received esophagogastrie intramural anastomosis at Second Affiliated Hospital of Xi'an Jiaotong University from January 2002 to October 2008 were retrospectively analyzed.Sixty-five patients who received stapled anastomosis during the same period were in control group.Postoperative conditions of patients in the 2 groups were compared by chi-square test and t test.Results (1)Reflux condition:there were 3 patients with degree I and 63 without reflux in test group,and 23 with degree Ⅰ,19 with degree Ⅱ,7 with degree Ⅲ and 16 without reflux in control group.There was a significant difference between the 2 groups(X~2=137.3,P<0.05);(2)results of barium meal fluoroscopy:12 patients in test group and 41 patients in control group had barium reflux,with significant difference between the 2 groups(X~2=27.4,P<0.05);(3)results of gastroscopy:9 patients in test group and 46 patients in control group had morphological changes of mucosa,with significant difference between the 2 groups(X~2=43.5,P<0.05);(4)esophageal sphincter pressure:the pressure of lower esophageal sphincter was(3.4±0.8)kPa in test group and(2.5±0.6)kPa in control group,and the pressure of upper esophageal sphincter wag(7.4±1.7)kPa in test group and(4.2±0.8)kPa in control group.There was a significant difference in esophageal sphincter pressure between the 2 groups(t=4.98,11.59,P<0.05).Conclusion Esophagogastric intramural anastomosis can partly restore the cardiac function and prevent reflux esophagitis effectively.

ABSTRACT:Objective To study the effects of arotinolol,propranolol and carvedilol on rat portal hypertension and make a comprehensive evaluation of the three drugs.Methods Portal hypertension was induced with CCl4 in rats.Arotinolol,propranolol,and carvedilol were administered for 2 weeks after the model was stable.Mean arterial pressure (MAP),heart rate (HR)and portal venous pressure (PVP)were measured at intubation;α-SMA expression was measured by immunohistochemistry;Masson staining was used to test collagen fibers area.Results Compared with model group,both arotinolol and carvedilol could significantly reduce PVP level (P <0.001),which was lower than that in propranolol group (P <0.001,P =0.032).Compared with those in model group,both MAP and HR in arotinolol group and carvedilol group were significantly reduced (P <0.05),MAP in carvedilol group was lower than in arotinolol group (P = 0.01 1 ).MAP was obviously decreased in propranolol group compared with model group (P =0.003),but HR had no sighificant difference between the two groups (P =0.143).Only TBIL in arotinolol and propranolol groups reduced significantly compared with model group (P <0.001 ).However,ALT, ALB and TBIL were obviously ameliorated in carvedilol group compared with model group (P <0.001,P <0.001, P =0.045).The expression ofα-SMA and the area of collagen fibers in arotinolol,carvedilol and propranolol groups
significantly declined compared with those in model group (P <0.05 ).Conclusion Arotinolol can significantly reduce cirrhotic rats’ portal pressure,with effects similar to those of carvedilol.The effect of arotinolol in improving liver function is weaker than that of carvedilol,but the side effects on MAP are milder than those of carvedilol.

200 papers on nerve root type cervical spondylosis treated with Chinese medicine were retrieved and 38 papers with complete diagnostic criteria and medical statistics were included for study. The results showed acupuncture, massage, and herbal therapy were three common methods and have their own advantage, but systemic, standardized and normative treatment program was lack. In the meantime of treating nerve root type cervical spondylosis, prevention should also be paid attention. The treatment, prevention and exercise on the whole therapeutic idea should be established, which has far-reaching significance.

This study was aimed to evaluate the feasibility of wind-warm lung-heat disease (non-severe community-acquired pneumonia, CAP) from the clinical curative effect, hospitalization days, medical expenses and other aspects. This study selected 198 wind-warm lung-heat disease (non-severe CAP) inpatients from January, 2012 to December, 2012 with the conventional therapy in the Respiratory Department, Wuhan Integrated Traditional Chinese Medicine (TCM) & Western Medicine Hospital as the control group. And another 179 wind-warm lung-heat disease (non-severe CAP) inpatients were selected from January, 2013 to December, 2013 with the TCM clinical pathway treatment in the Respiratory Department of the same hospital as the treatment group. Retrospective analysis was used to compare the clinical curative effects, hospitalization days, and medical cost differences. The results showed that TCM clinical pathway for wind-warm lung-heat disease (non-severe CAP) can shorten the hospitalization days and reduce patients’ medical costs, and ensure the clinical curative effects. It was concluded that the standardized TCM clinical pathway had positive effect on wind-warm lung-heat disease (non-severe CAP). Therefore, the formulation and implementation of TCM clinical pathway was of great significance in the treatment of wind-warm lung-heat disease (non-severe CAP).

Objective To explore the effects of volatile oil and 2-undecanone from Houttuynia Cordata Thunb. (H. cordata) on LPS-TLR4 / MD-2-TNF-α signaling pathway. Methods TLR4 / MD-2 blocking agent was used to mask the TLR4 /MD-2 site,then protein expression levels of TLR4 in cells treated with volatile oil and 2-undecanone were analyzed by western blot. ELISA was used to detect the secretion of the inflammatory cytokines such as TNF-α,IL-1β and IL-10. Comparison analysis was then performed from the results of cell experiments in vitro and anti-inflammatory effects through xylene-induced ear edema test in vivo. Results In concentrations between 1 to 10 μg · mL-1 ,Houttuynia volatile oil showed better effect than 2-undecanone on inhibition of TLR4 protein in LPS-induced RAW264. 7 cells, and had some differences in the effects on inflammatory factors. Compared with the LPS+TLR4 / MD-2 group,the LPS+TLR4 / MD-2 + volatile oil group had no significant difference in the expression of TLR4 protein (P>0. 05),but the LPS+TLR4 / MD-2 +2-undecanone group reduced the expression of TLR4 protein obviously. It appeared that volatile oil exerts its anti-inflammatory effect through LPS-TLR4 / MD-2-TNF-αpathway,but 2-undecanone may exert its anti-inflammatory effect by other means. Houttuynia volatile oil showed better anti-inflammatory activity than 2-undecanone in vivo at the same dose. Conclusion There are some differences in anti-inflammatory effects and related mechanisms between volatile oil and 2-undecanone, probably owing to the synergistic effects of multi-ingredients in the volatile oil.
