Objective To analyze the clinical characteristics,prevention,treatment and prognosis of patients with measles,and provide data for further prevention and complication control.Methods Data of 177 patients with measles were collected and analyzed retrospectively.Results Infants (79.1％) and adults (20.9％) accounted for the most part.The clinical symptoms of measles were typical and Koplik's was very common.The incidences of bronchitis and bronchial pneumonia were higher(33/140,22.6％) in infant patients than that in adults,which was more serious in adult patients,and usually accompanied by liver damage (34/37,89.2％).Conclusion Currently measles is mainly typical,and the incidence in children and adults is increasing.In order to control measles,measles antibody titer monitoring and vaccination of measles should be strengthened.

Objective: To evaluate the intestinal trophic effects and adverse reactions of nasojejunal and jejunostomy tube im-plants on patients with total gastrectomy. Methods:A total of 86 patients with advanced gastric cancer were randomly and equally di-vided into two groups. Groups A and B received enteral nutrition therapies through nasojejunal and jejunostomy feeding tube implants, respectively. The therapeutic efficacy of the two methods of enteral nutrition therapy and the corresponding adverse reactions observed in the two groups were compared. Results:Group B patients demonstrated shorter anal evacuation and defecation times than group A patients, the difference is statistically significant (P<0.05). Moreover, the bodyweight, total protein, and albumin levels of the patients significantly decreased in both groups after enteral nutrition therapy was administered (P<0.05). Postoperative nutritive indexes were higher in group B than in group A;however, no significant difference was obtained between the two groups (P>0.05). Nonetheless, the patients in group B tolerated the treatment well compared with those in group A (P<0.05). The complication rates of groups A and B were 18.6%and 23.3%, respectively, but this difference was not significant (P>0.05). Conclusion:Patients subjected to total gastrecto-my showed higher tolerance to jejunal tube implants for enteral nutrition than to nasojejunal tube implants, indicating that jejunal tube implants can be used to improve the nutritional status of patients.

Objectives To investigate the risk factors for rheumatoid arthritis in middle-aged and elderly residents in Luohe City,Henan Province.Methods Survey questionnaires and measurements of biochemical parameters were conducted in individuals 45 years old or above,using the two-stage cluster sampling method.Risk factors for rheumatoid arthritis were evaluated according to the criteria for the classification of RA by the American College of Rheumatology and European League Against Rheumatism(ACR/EULAR) (2010).Results Among the 8 610 residents covered by the survey,8,274 people responded,representing a response rate of 96.1％.There were 3 361 male (40.62％)and 4 913 female(59.38％)respondents,with an average age of 61.4±7.4(45-91)years.The age group of 60-64 years had the highest rates of joint involvement,with those scoring 2,3 and 5 points at 2.90％,2.02％ and 0.26％,respectively.The rheumatoid factor (RF)and the anti-cycliccitrullinatedpeptide(anti-CCP)antibody titer showed skewed distributions.The low titer-positive rate of RF and anti-CCP antibody,the ESR and CRP in female residents were evidently higher than in male residents(each P＜0.05).Smoking was an independent factor for RA(OR:1.79,95 ％CI:1.34～ 3.41,P＜0.01).The risk for RA occurrence increased with the frequency of drinking ＞1 time/d(OR:6.71,95 ％ CI:0.88 ～ 51.23,P＜ 0.01).The prevalence of RA was significantly higher in rural areas than in urban and suburb areas(0.93％ to 0.48％ and 0.53％,each P＜0.05).Living on higher floors was a protective factor for RA (OR:0.61,95 ％ CI:0.36 ～ 0.94,P =0.036).Family history was an independent risk factor for RA (OR:3.09,95 ％ CI:1.53 ～ 6.27,P ＜ 0.01),and being first degree relatives of RA patients was a risk factor(OR=6.45,95 ％ CI:1.67～ 17.83,P＜0.01).Multiple factor analysis showed that female gender,first floor of residential buildings,smoking and genetics were key risk factors for RA.Conclusions The risk factors for rheumatoid arthritis in middle-aged and elderly residents in Luohe City of Henan Province are female gender,smoking and genetics.

Prior to the formation of new metastases,a large number of cancer cells released from the primary tumor enter the dormancy period.Once the dorruancy is broken,tumor cells will recover the capability of proliferation.In recent years,various hypotheses and mechanisms of tumor metastasis have been studied.Primary tumor resection is considered to be an important factor to break tumor dormancy state.It is recognized as an important reason to promote tumor metastasis.The improvement of surgical technique and further study on the mechanism of dormancy may provide new ideas for the treatment of metastatic tumor.

Following Escherichia coli lysis with alkali, cetyltrimethylammonium bromide (CTAB) was directly titrated into the supernatant. An easy and feasible technology for plasmid purification was established with the optimized proportion between the quantity of CTAB and plasmid, combined with the specific solution for DNA release and TritonX-114 for endotoxin removal. Quality detection showed that the purified plasmid was free of contamination of host RNA. The host bacterial genomic DNA, endotoxin and bacterial protein were less than 10 microg, 50 EU and 10 microg per mg plasmids, respectively. The ratio of OD260/OD280 was between 1.75-1.85. Eighty percent of the prepared plasmids were presented in the supercoiled form. The plasmid purified with this technology can satisfy all criteria stipulated by FDA. The main advantages of the technology include the avoidance of animal-derived enzymes such as ribonucleases A, Proteinase K and toxic reagents like chloroform and phenol. In addition, the technology has low cost and no pollution.

The aim of this paper is to explore the prevention of rabbit postoperative abdominal cavity adhesion with poly (lactic-co-glycotic acid) (PLGA) membrane and the mechanism of this prevention function. Sixty-six Japanese white rabbits were randomly divided into normal control group, model control group and PLGA membrane group. The rabbits were treated with multifactor methods to establish the postoperative abdominal cavity adhesion models except for those in the normal control group. PLGA membrane was used to cover the wounds of rabbits in the PLGA membrane group and nothing covered the wounds of rabbits in the model control group. The hematologic parameters, liver and kidney functions and fibrinogen contents were detected at different time. The rabbit were sacrificed 1, 2, 4, 6, 12 weeks after the operations, respectively. The adhesions were graded blindly, and Masson staining and immunohistochemistry methods were used to observe the proliferation of collagen fiber and the expression of transforming growth factor β1 (TGF-β1) on the cecal tissues, respectively. The grade of abdominal cavity adhesion showed that the PLGA membrane-treated group was significant lower than that in the model control group, and it has no influence on liver and kidney function and hematologic parameters. But the fibrinogen content and the number of white blood cell in the PLGA membrane group were significant lower than those of model control group 1 week and 2 weeks after operation, respectively. The density of collagen fiber and optical density of TGF-β1 in the PLGA membrane group were significant lower than those of model control group. The results demonstrated that PLGA membrane could be effective in preventing the abdominal adhesions in rabbits, and it was mostly involved in the reducing of fibrinogen exudation, and inhibited the proliferation of collagen fiber and over-expression of TGF-β1.

OBJECTIVETo investigate the effects of PLGA absorbable membrane in prevention of postoperative abdominal adhesion in rabbits.

METHODS66 Japanese white rabbits were randomly divided into three groups: the normal control group n = 6, model control group n = 30 and PLGA group n = 30. Rabbits were received multifactor methods to establish postoperative abdominal adhesion models except for normal control group. The cecum wound was covered PLGA membrane in the PLGA group. At postoperative 1, 2, 4, 6 and 12 weeks, the abdominal cavities were reopened and the adhesive severity was graded blindly, and the hydroxyproline level in cecum tissue was measured and the cecum histopathology was observed.

RESULTS(1) the degree of adhesion and hydroxyproline level in model control group were significantly higher than those of normal control group (P < 0.05, P < 0.01), while the degree of adhesion and hydroxyproline level in PLGA group were significantly lower than those of model control group (P < 0.05). (2) HE staining showed that cecum serosa had obviously inflammatory cell infiltration and fibroblast proliferation, while PLGA could inhibit fibroblast proliferation and reduce the inflammatory cell infiltration and collagen.

CONCLUSIONPLGA absorbable membrane can inhibit fibroblast proliferation and collagen to prevent the experimental postoperative peritoneal adhesions.
