300 cases of atrophic gastritis were typed into 3 groups according to TCM principle, viz. Qideficiency of the Spleen-Stomach, Yang-deficiency of the Spleen-Stomach and Yin-deficiency of the Spleen-Stomach. Biopsy specimens were examined pathologically and detection of Helicobactor pylori performed for comparism. Results showed that in the Yin-deficiency type, the severity of lesion in the gastric mucosa and its type of lesion, severity of atrophy of mucosal glands, infiltration of interstitial inflammatory cells were most serious, while for the detection of Helicobactor pylori, it made no difference among all the three types.

Observe and study the morphological changes and effects on yoleperoxidase (MPO) of traditional Chinese medical complex Intestine-clearing Suppository (ICS) in preventing and treating ulcerative colitis (UC).Method.. Divide the experimental rats randomly into 6 groups, i.e., blank, salicylazosulfapyridine (SASP), model, high, middle and low dosage of ICS, except the blank group, makeother rats experimental UC model with albumen immunologic method of rabbit colon mucosa, further divide them randomly into 2 experimental groups, i. e. , prevention and treatment, afterwards at 2nd~21st day, give prevention group the medicine, 22nd~35th day, treatment group, then decapitate them and take the colon tissue, and observe it morphologically under optical microscope, measure active MPO, analyse statastic results. Result: Through general morphological observation ,we found there were serious congestion ,edema, mucosa erosion, many large ulcers in the rats of model group; less serious mucosa erosion and quantity of ulcers in SASP and low-dosage ICS groups: small ulcers, not serious mucosa erosion, low degree of congestion and edema in high-and middle-dosage ICS groups; the scores of inflammatory injury of ICS groups were markedly lower than that of model (P＜0. 01), meanwhile, the preventive and reating effectiveness of high-and middle-dosage groups was better than that of SASP (P＜0.05). Under the optical microscope, there were large area of mucosa coloboma in the rats of model group, the ulcer penetrated to muscular layer and serous coat; in SASP group and low-dosage ICS group, there were erosive mucosa and inflammatory cell infiltration, granulation on the base; in middle-and high-dosage groups, large part of colon mucosa recovered, granulation formed on the base, ulcers were obviously less than that in model group (P <＜0.01); there had marked difference compared with that in SASP group (P＜0.05). The MPO active values of high-and middle-dosage groups were markedly lower than that of model group (P ＜ 0.01). Conclusion: Traditional Chinese complex ICS had good prevention and treatment to rats UC, itseffectiveness was positively correlated with dosage and better than that of SASP suppository.

Drug resistance of Acinetobacter baumannii ( Ab) in surgical ICU from January 2008 to December 2009 was investigated retrospectively. Total 114 clinical strains of Ab were isolated from surgical ICU and 92 strains were from respiratory tract (80.7% ). The prevalence rate of multiresistant Ab in 2009 was higher than that in 2008 (75. 7% vs 50. 0% , x2 = 7. 703, P = 0. 006). The results indicate that to monitor and control drug resistant of Ab constantly is important for the prevention of nosocomial infection.

METHODS The expression of MMP-2 and MVD were detected in the specimens of 50 cases with nasopharyngeal carcinoma and 15 cases with nasopharyngeal inflammation by immunohistochemical technique. RESULTS The MVD in nasopharyngeal carcinoma(21.92?7.80) was significantly higher than that in inflammation nasopharyngeal tissues (9.23? 1.84, P

Objective:To evaluate the role of HPV16E6,cyclin D1,and human telomerase transcriptase(hTERT) in the development and progression of nasopharyngeal carcinoma(NPC) and to discuss the clinical significance.Methods: Immunohistochemistry was used to detect the expression of HPV16E6,cyclin D1,and hTERT in paraffin-embedded nasopharyngeal carcinoma tissues and nasopharyngeal chronic inflammation tissues.The relationship between their expression with the clinicopathological features of NPC was analyzed;the influence of their expression on prognoses of patients was also analyzed.Results: The positive rates of HPV16E6,cyclin D1,and hTERT in NPC tissues were 62.5%(35/56),50.0%(28/56),and 67.9%(38/56),respectively,which were significantly higher than those in the inflammation tissues(P0.05).HPV16E6 expression was positively correlated with cyclin D1(r=0.480,P

Objective To investigate the malnutrition status among the elderly in age care institutions in Shanghai suburb and analyze its potential influential factors.Methods The MiniNutritional Assessment (MNA) was adopted to evaluate the nutritional status of the 190 elderly people in age care institutions.The dietary supply by the institution canteen and the quantity of residual food left by the malnourished elderly people were weighted.Results In the age care institutions,the malnutrition rate reached 23.7％,47.9％ of the elderly people were at the risk of malnutrition,and only 28.4％ of the elderly people were well nourished.Logistic regression analysis showed that the major influential factors for malnutrition in the elderly people were food intake ability,mobile capability,chewing and swallowing ability,ageing and mental Illness.The malnourished elderly people had the most residual meat and vegetables,and insufficiency of nutrient intake was the main cause for the malnutrition in the elderly people.Conclusions The elderly people in age care institutions in Shanghai suburb have the higher risk of malnutrition.The malnutrition occurs under influence of many factors,of which some are unavoidable,however,some factors like dietary factors can be changed to improve the nutritional status of the elderly people in age care institutions.

Objective To compare the organ coefficients and expressions of hypoxia-related genes in Bama and Juema pigs.Method Real-time quantitative PCR was used to detect the changes of hypoxia gene expressions in the heart,liver,spleen,lung,and kidney of Juema and Bama miniature pigs.Results The organ coefficients of kidney and spleen of Juema pigs were significantly lower than Bama miniature pigs (P<0.05 for both).The heart and lung coefficients of Juema pigs were significantly higher than that of Bama miniature pigs (P<0.05 for both).The VEGF and HIF-1α expressions in the lung and kidney in Juema pigs were significantly higher than Bama pigs (P<0.05 or P<0.01).Only the EPO expression in in the lung of Juema pigs was significantly higher than that of the Bama miniature pigs (P<0.05).Conclusions These results indicate that the variation in organ coefficients may be resulted from evolutionary factors such as adaptiveness to environmental physical and energy conditions,pathogens,and energy metabolism demands,etc.in combination.Juema miniature pigs showing a significantly higher expression of hypoxia-related genes than that in Bama minipigs indicate that it has a strong plateau adaptability by higher gene expressions.

OBJECTIVE:To observe clinical efficacy and safety of Mailuoning injection in adjunctive treatment of acute cere-bral infarction. METHODS:A total of 65 patients with acute cerebral infarction selected from neurology department of our hospital were divided into control group(32 cases)and observation group(33 cases)according to random number table. Control group was given conventional treatment. Observation group was additionally given Mailuoning injection 10 mL added into 0.9% sodium chlo-ride injection 250 mL intrnrenously,ivgtt,qd,on the basis of control group. Both group were treated for 15 d. Clinical efficacy as well as serum levels of ox-LDL,BNP and MMP-9,NIHSS score before and after treatment,the occurrence of ADR were com-pared between 2 groups. RESULTS:The response rate of observation group was 90.91%,which was significantly higher than 65.63%,with statistical significance(P<0.05). Before treatment,there was no statistical significance in serum levels of ox-LDL, BNP or MMP-9,NIHSS score between 2 groups (P>0.05). After treatment,serum levels of ox-LDL,BNP and MMP-9,NIHSS score in 2 groups were all decreased significantly,and the observation group was significantly lower than the control group,with statis-tical significance (P<0.05). There was no statistical significance in incidence of ADR between 2 groups (P>0.05). CONCLU-SIONS:Mailuoning injection has significant therapeutic efficacy for acute cerebral infarction,can significantly reduce serum levels of ox-LDL,BNP and MMP-9,promotes neurological function and the recovery of patients with cerebral infarction with good safety.

Objective To investigate the difference of the expression of hypoxia reaction genes of vascular endothelial growth factor(VEGF),erythropoietin (EPO) and hypoxia-inducible factor-1 alpha (HIF-1α)) at different times of rats that were induced epilepsy by kainic acid (KA),and analyze their correlation.Methods The epileptic rat model was established by intraperitoneal injection of kanic acid.The expression of VEGF,EPO and HIF-1α gene were detected by real-time fluorescent quantitative PCR assay with TaqMan probe in different times after intraperitoneal injection of KA.Results Compared with normal sodium (NS) group,the expression VEGF was higher at 12 h((8.38±1.27) ×10-3 ng/μl,P＜0.05)) and 24 h((8.30±5.08) ×10-3 ng/μl,P＜0.05)),EPO was higher at 12 h((8.42±0.90) × 10-5 ng/μl,P＜0.05)) and 48 h ((1.50±3.25) × 10-2 ng/μl,P＜0.01)) while the HIF-1α was higher at 24 h((2.11±0.21) × 10-2 ng/μl,P＜0.01)),48 h((1.50±0.33) × 10-2 ng/μl,P＜0.05))and 72 h((1.64±0.16) × 10-2 ng/μl,P＜0.01)).Furthermore,the expression of EPO showed significant correlations with HIF-1α and VEGF (r=0.573,0.471,P＜0.05),VEGF and HIF-1α had eminent correlations (r=0.803,P＜0.01).Conclusions The expression of VEGF,EPO and HIF-1α participate in the seizure procedure and there is certain correlation between the three genes.

Objective To compare the Bama minipig and Juema minipig models of high altitude multi-organ dysfunction syndrome.Methods Six plateau-origin Juema minipigs and plain-origin Bama minpigs in each group received intravenous infusion of 0.35 mg/kg lipopolysaccharide ( LPS) , respectively.Blood samples were taken at 0 h, 3 h, 6 h, 12 h, 24 h, 48 h and 72 h after LPS infusion.Routine blood test was performed, blood CK, AST, ALT, TBIL, CRE were assayed, and histopathological examination of the lung tissues was performed at 24 h, 48 h after LPS infusion.Results The mortality of Bama minipigs was 33.3%, higher than that of 16.7%of Juema minipigs.The trend of physiological and biochemical changes was similar, but was milder in the Juema minipigs than in Bama minipigs.The lung injuries of the Bama minipigs at 24 h and 48 h were more severe than those in the Juema minipigs.Conclusions Both Bama and Juema minipig models of high altitude multi-organ dysfunction syndrome can be successfully established.Juema minipig models can be more closely and safely established, due to its own plateau biological properties, and avoid the influence by extrinsic injurious effects of plateau environment.
