Objective:We had analyzed the attitude of science researchers in a university to promote the development of science cause in the university. Method:We had made a prevalence survey through a questionnaire. Results:Some researchers join in science cause to acquire some profits,they often change their research orientation and they aren’t willing to cooperate with each other. Conclusion:We must initiate a kind of spirit of which advantageous to collaborate,insisting,struggling and seeking the truth of science.

OBJECTIVE:To observe the efficacy and safety of rebamipide triple therapy in the treatment of gastric ulcer with bleeding. METHODS:130 patients with gastric ulcer with bleeding were randomly divided into control group(65 cases)and obser-vation group(65 cases). Control group received Omeprazole enteric-coated capsule 20 mg,orally,twice a day+Aluminum magne-sium carbonate tablet 500 mg,orally,once a day;observation group was additionally received Rebamipide tablet 0.1 g,orally,3 times a day. They were treated for 12 weeks. Clinical efficacy,remission time of belching,abdominal pain,bloating,hematemesis/hematochezia,clinical symptom score before and after treatment,rebleeding and the incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,remission time of symptoms and signs were significantly shorter than control group,the incidence of rebleeding was significantly lower than con-trol group,with statistical significances (P<0.05). Before treatment,there was no significant difference in the clinical symptom score (P>0.05). After treatment,the clinical symptom scores in 2 groups were significantly lower than before,and observation group was lower than control group,with statistical significances (P<0.05). And there was no significant difference in the inci-dence of adverse reactions (P>0.05). CONCLUSIONS:Rebamipide triple therapy shows obvious short-term efficacy in the treat-ment of gastric ulcer with bleeding,which can effectively improve patients'gastrointestinal symptoms,reduce rebleeding risk,and does not increase the incidence of adverse reactions.

Objective: To observe the effect of puncturing Juliao (GB 29) in treating carpal joint sprain. Methods: 99 cases were randomly divided into 3 groups, treatment, control 1 and control 2 groups, 33 cases for each group. Cases in treatment group were treated by acupuncture on Juliao (GB 29); patients in control 1 group were treated by acupuncture at Sanyinjiao (SP 6), and patients in control 2 group were treated by local application. The clinical effect was compared among three groups after the treatment. Results: The effective rate in the treatment group is 96.9%, which is over and above 84.8% in control 1 group and 75.8% in control 2 group (both P＜0.05). Conclusion: Acupuncture at Juliao (GB 29) has a precise curative effect in treating sprain of carpal joint. It is more effective than acupuncture at Sanyinjiao (SP 6) and local application.

Objective To explore the changes of platelet count in children with bronchial pneumonia and its clinical significance in the disease.Methods 320 cases of bronchial pneumonia were retrospectively analyzed after hospitalization.According to the number of platelet count,the cases were divided into increased platelet count group (>400 ×109 /L)and normal platelet group(100 -400 ×109 /L),and the clinical data of two groups were statistically analyzed,such as age,gender,dyspnea,treatment,white blood cell count,hemoglobin,C -reactive protein.Results In 320 cases,62 cases'platelet count increased,258 cases were normal.Compared with the normal platelet group,the cases in increased platelet count group had the following characteristics:younger(<1 year old mainly,accounted for 46.77%;the former was between 1 and 3 years old mainly,accounted for 40.70%;Z =2.08),treatment time pro-longed (7.37 ±1.90)d,the former was (6.79 ±1.51)d,white blood cell count increased [(10.71 ±3.91)×109 /L,the former was (9.37 ±3.56)×109 /L,t =2.61,P <0.05];the incidence rate of dyspnea was higher (74.19%, the former was 52.33%,χ2 =9.73),hemoglobin decreased [(104 ±14)g/L,the former was (111 ±13)g/L,t =3.34],C -reactive protein increased [(24.42 ±12.73)mg/L,the former was (18.31 ±8.86)mg/L,t =3.58,P <0.01].There was no significant difference in gender between the two groups.Conclusion Children with bronchial pneumonia who platelet count increased are younger and their diseases are more serious.Observation the platelet count change can help to rightly judge and effective treat.

Objective To observe the effects of Kinesio taping on upper limb spasticity after stroke. Methods From March to Novem-ber, 2015, 39 stroke patients were divided into Kinesio taping group (Kinesio taping and rehabilitation, n=13), white taping group (white tap-ing and rehabilitation, n=13) and blank group (rehabilitation, n=13) randomly. They were evaluated with modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA) of upper limbs and the modified Barthel Index (MBI) before treatment, four and eight weeks after treat-ment. Results There was no significant difference among the three groups in the scores of FMA and MBI (P>0.05) four weeks after treat-ment, but the score of MAS improved more in the Kinesio taping group than in the other two groups (P<0.05). The scores of MAS, FMA and MBI all improved more in the Kinesio taping group than in the other two groups (P<0.05) eight weeks after treatment. Conclusion The application of Kinesio taping can relieve upper limb spasticity, and improve motor function and activities of daily living for patients with stroke.

Fetuin A is a kind of glycoprotein that is synthesized and secreted by the liver.It is a natural inhibitor of insulin receptor tyrosine kinase,which is involved in the formation of insulin resistance.It is closely related to the nonalcoholic fatty liver disease.This paper reviews the related research on effect of fetuin A in the occurrence and development of non-alcoholic fatty liver disease.

Objective To investigate the effect of protamine(PS)coated polylactic acid(PLA)nanocapsule on the immune response of murine bone marrow-derived dendritic cells(BMDCs).Methods PLA nanocapsules were prepared by W1/O/W2 method.Protamine was used to modify the surface of PLA nanocapsule that encapsulated ovalbumin(OVA),a model anti-gen.The prepared OVA/PLA/PS nanocapsules were used to stimulate BMDCs.Flow cytometry was used to analyze the ex-pression of surface molecules CD80,CD83,CD86,MHCⅠ,and MHC Ⅱ,and the uptake of nanocapsule.The levels of IL-12 p70 secreted by BMDCs were detected by ELISA.Results OVA/PLA/PS nanocapsules could significantly up-regulate the expres-sion of CD80,CD83,MHCⅠ,and MHC Ⅱ in BMDCs,and increase the secretion of IL-12 p70 by BMDCs.Furthermore,OVA/PLA/PS nanocapsules could enhance the uptake efficiency of OVA by BMDCs.Conclusion OVA/PLA/PS nanocapsule can en-hance the immune response of BMDCs,and may become a good drug delivery carrier.

Objective To observe the effect of functional exercise guided by self muscle strength in early rehabilitation on patients after total knee arthroplasty (TKA). Methods From September, 2014 to September, 2015, 62 patients after TKA were randomly divided into ex-perimental group (n=31) and control group (n=31). The control group received conventional rehabilitation training, while the experimental group received rehabilitation training under the guidance of their own muscle strength standard. The degrees of swelling and pain seven days after TKA; the muscle strength seven and 15 days after TKA; the range of motion (ROM), the Keen Society Score (KSS) 15 days after TKA;and the postoperative hospital stay were compared. Results There was no significant difference in all the indexes above between two groups before TKA (t<0.960, P>0.05), and all of them improved after TKA (t>3.470, P<0.01). There was no significant difference in the de-grees of swelling (t=1.800, P=0.077) and pain (t=0.840, P=0.404) seven days after TKA. The score of quadriceps strength was higher in the experiment group than in the control group (t>2.280, P<0.05) seven and 15 days after TKA. There was no significant difference in the ROM of the knee and the score of knee between two groups (t>0.850, P>0.05), and the functional score was higher in the experiment group than in the control group (t=5.870, P<0.001) 15 days after TKA. The postoperative hospital stay was shorter in the experiment group (t=7.65, P<0.01). Conclusion Functional exercise under the guidance of their own muscle strength standard could contribute to the improvement of postoperative muscle strength and knee joint function, and shorten the hospitalization stay.
