ResultAfter treatment， the total effective rate of the observation group ［95.35% （41/43）］ was significantly better than that of the control group ［79.07% （34/43）］， and the difference was statistically significant （χ2=5.108， P<0.05）. After treatment， the scores of the primary and secondary TCM syndromes in the observation group and the control group were significantly decreased （P<0.05）. After treatment， the scores of primary and secondary TCM syndromes in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the pathological scores of gastric mucosa atrophy， activity， chronic inflammation， intestinal metaplasia， and dysplasia were significantly lower in the observation group and control group （P<0.05）. After treatment， the pathological scores of gastric mucosa atrophy， activity， chronic inflammation， intestinal metaplasia， and dysplasia in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the Hp conversion rate in the observation group was significantly increased compared with the control group （P<0.05）. After treatment， the levels of inflammatory indicators NLR and IL-1β in the observation group and control group were significantly lower （P<0.05）， and the levels of inflammatory indicators NLR and IL-1β in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the levels of PGI and PGⅠ/PGⅡ in the observation group and control group were significantly higher （P<0.05）， and the levels of PGI and PGⅠ/PGⅡ in the observation group were significantly higher than those in the control group （P<0.05）. After treatment， the G-17 level of the observation group and the control group was different at different time points （P<0.05）， and the G-17 level of the observation group was higher at different time points than that of the control group （P<0.05）. The G-17 level of the observation group had an increasing trend compared with the control group （P<0.05）. There was no significant difference in the risk of adverse reactions between the two groups. ConclusionThe combination of Jianpi Huoxue prescription and acupuncture can effectively alleviate symptoms， increase Hp negative conversion rate， inhibit inflammation， and regulate PG and G-17 levels in CAG patients， thus controlling or even reversing gastric mucosal atrophy and reducing the probability of its progression to gastric cancer.

Correlation factors analysis on postoperative delirium of elderly patients with intertrochanteric fracture fixation / 局解手术学杂志

Objective To investigate the risk factors of delirium in elderly patients with intertrochanteric fracture after internal fixation.Methods The data of 160 patients with intertrochanteric fractures who received internal fixation in our hospital from January 2012 to July 2014 were analyzed retrospectively.The risk factors such as age,sex,preoperative complications,preoperative cognitive function,fracture location,operation mode,operation time,anesthesia method,hospital-to-operation time and intraoperative blood loss were summarized.Results The incidence of postoperative delirium was 28.15％ in postoperative elderly patients with intertrochanteric fractures.Univariate analysis showed that delirium had correlated with preoperative cognitive impairment,preoperative preparation time,serum sodium,fentanyl,atrial fibrillation,anesthesia method,operation time and perioperative blood loss (P ＜ 0.05).The multivariate Logistic regression analysis showed that the independent risk factors of postoperative delirium were preoperative cognitive dysfunction,operative time more than 2 hours and preoperative preparation time more than 4 days.Conclusion The occurrence of postoperative delirium was associated with anesthesia method,cognitive deficits,preoperative preparation time and perioperative blood loss.The anesthesia method which had less effect on the whole body condition and less time of operation preparation can decrease the occurrence of postoperative delirium in a certain extent,which is conducive to improving the prognosis.

Helicobacter pylori negative peptic ulcer and ulcer bleeding:a multi-center case-control study in China mainland / 中华消化内镜杂志

Objective The primary aim of this study was to examine the proportion and natural history of Helicobacter pylori (Hp) negative bleeding peptic ulcers. Methods The study was designed as a multiple-center, case-control study conducted in 14 endoscopy centers in China from April 2006 to March 2007. Each center was expected to recruit 30 peptic ulcer patients with bleeding ( PUB group) and 30 without (PU group). All screened patients with upper gastrointestinal bleeding received endoscopy within 24 hours of admission. Biopsy specimens were taken from the antrum to determine Hp infection by rapid urease test and pathology. Patients with negative Hp infection at first examination were asked to receive urease breathe test (UBT) one month later. Results A total of 617 patients were enrolled with 263 in PUB group and 354 in PU group. There is no significant difference in demographic characters between 2 groups ( P ＞0. 05). The rate of Hp infection in PUB group ( 161/263, 61.2% ) was significantly lower than that in PUgroup (311/354, 87. 9%, P ＜0. 001 ). The incidence of complex ulcer in Hp positive PUB patients was 7.5% ( 12/161 ), which is significantly higher than that in Hp negative PUB patients ( 1/102, 1.0% , P =0. 018). In PUB group, no significant differences were found between Hp positive and negative patients in regarding of age, sex, rates of haematemesis, duodenal ulcer and gastric ulcer, and size of ulcer ( P ＞0. 05 ). Among 102 Hp negative cases in PUB, no positive case was found in UBT one month later. Conclusion We have demonstrated a rise in the incidence of Hp negative bleeding ulcers in China. The idiopathic ulcer was not rare, and might have a higher tendency to cause bleed.

Therapeutic effects of Tiaozhong Granule on esophagus mucous membrane in rats with mixed reflux esophagitis and the mechanisms / 中西医结合学报

OBJECTIVE: To explore the mechanism of Tiaozhong Granule (TZG), a compound traditional Chinese herbal medicine, in treating rats with mixed reflux esophagitis. METHODS: Fifty-eight SD rats were randomly divided into untreated group (n=12), sham-operated group (n=10), TZG-treated group (n=12), Banxia Xiexin Decoction (BXXXD)-treated group (n=12) and cisapride-treated group (n=12). Mixed reflux esophagitis was induced by esophago-duodenum end-to-side anastomosis. Four weeks later, the rats were orally administered twice daily for 12 days. Pathological changes of esophagus mucous membrane were observed by using HE staining. The expressions of proliferating cell nuclear antigen (PCNA) and p53 in the esophagus tissue were detected by immunohistochemical SABC method. Spectrophotometric method was used to detect the content of malondialdehyde (MDA) and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in serum. RESULTS: Compared with the untreated group, pathological changes of esophagus mucous membrane were relieved in different degrees in TZG-treated group, BXXXD-treated group and cisapride-treated group. Content of MDA and expressions of PCNA and p53 were obviously decreased in the three treated groups (P<0.01), and the activities of SOD and GSH-Px were significantly increased in the three treated groups (P<0.05, P<0.01). TZG had better effects than cisapride in decreasing the content of MDA and increasing the activities of SOD and GSH-Px (P<0.05). TZG was better in aspect of reducing the expressions of PCNA and p53 than BXXXD and cisapride tablets (P<0.05). CONCLUSION: Tiaozhong Granule can treat mixed reflux esophagitis in rats, and its action mechanisms may be associated with decreasing the expressions of PCNA and p53 in esophagus mucous membrane, reducing the content of MDA and increasing the activities of SOD and GSH-Px in serum.

Protective effect of Huaxia shallot preparation on human umbilical vein endothelial cell injury induced by oxidized low density lipoprotein and its mechanism / 中西医结合学报

OBJECTIVE: To observe the protective effect of Huaxia shallot preparation on human umbilical vein endothelial cell (HUVEC) injury induced by oxidized low density lipoprotein (Ox-LDL) in vitro. METHODS: Ox-LDL was prepared and identified, and HUVECs were cultured. After 2-hour intervention of different drugs and 24-hour following intervention of Ox-LDL, the number of HUVECs was observed by phase contrast optical microscope and the activity of the HUVECs was observed by methyl thiazolyl tetrazolium (MTT) technique. Superoxide dismutase (SOD) activity and nitric oxide (NO) content were assayed by respective kit. The protein expressions and mRNA levels of peroxisome proliferators activated receptor gamma(PPAR-gamma) and endothelial nitric oxide synthase (eNOS) were measured by western blot technique and reverse transcription polymerase chain reaction (RT-PCR). RESULTS: Ox-LDL could increase the apoptosis rate of the HUVECs and decrease the NO release as compared with the blank control group (P<0.05). These effects induced by Ox-LDL were all significantly inhibited by Huaxia shallot preparation. It could up-regulate the protein expressions and mRNA levels of PPAR-gamma and eNOS significantly (P<0.05). Huaxia shallot preparation could decrease the apoptosis rate of the HUVECs. CONCLUSION: Ox-LDL may be involved in the initiation and progression of atherosclerosis by injuring the endothelial cells directly and may cause the endothelial dysfunction. Huaxia shallot preparation can protect against Ox-LDL induced endothelial cell injury by up-regulating the protein expressions and mRNA levels of PPAR-gamma and eNOS. It suggests that Huaxia shallot preparation may play a role in the prevention and treatment of cardiovascular disease.
