Objective To evaluate the effects of acupuncture of acupoints selected on postsurgical gastrointestinal dysfunction in the patients undergoing non-gastrointestinal abdominal surgery.Methods A total of 160 patients of both sexes,aged 18-64 yr,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective non-gastrointestinal abdominal surgery under general anesthesia,were randomly divided into 4 groups (n =40 each) using a random number table:control group (group C),common acupuncture group (group CA),acupuncture of acupoints selected group (group SA),and acupuncture of non-acupoint group (group NA).Acupuncture was performed at 30 min before induction of anesthesia in CA,SA and NA groups.Group CA received acupuncture at bilateral Taichong and Neiguan acupoints,group SA at bilateral Zusanli and Hegu acupoints,and group NA at the points 1 cm lateral to the acupoints of Zusanli and Hegu once every 30 min until the end of surgery.The time when the patients passed flatus,defecating time,and recovery time of bowel sounds were recorded after surgery.The occurrence of nausea and vomiting was recorded within 1 day after surgery.The electrogastrogram (EGG)was performed at 1 day before surgery and 2 days after surgery,and the frequency,amplitude and rhythm of EGG were recorded.At 1 day before and after surgery,the levels of plasma motilin and gastrin were determined using enzyme-linked immunosorbent assay.The recovery of postsurgical gastrointestinal function was assessed,and the recovery rate was calculated.Results Compared with group C,the incidence of postsurgical nausea and vomiting was significantly decreased,the time when the patients passed flatus,defecating time,and recovery time of bowel sounds after surgery were significantly shortened,the recovery rate was significantly increased,the frequency,amplitude and rhythm of EGG were significantly increased at 2 days after surgery,and the levels of plasma motilin and gastrin were significantly increased at 1 day after surgery in CA and SA groups (P＜0.05).Compared with group CA,the incidence of postsurgical nausea and vomiting was significandy decreased,the time when the patients passed flatus,defecating time,and recovery time of bowel sounds after surgery were significantly shortened,the recovery rate was significantly increased,the frequency,amplitude and rhythm of EGG were significantly increased at 2 days after surgery,and the levels of plasma motilin and gastrin were significantly increased at 1 day after surgery in group SA (P＜ 0.05).Conclusion Acupuncture of acupoints selected provides better efficacy than common acupuncture in improving postsurgical gastrointestinal dysfunction in the patients undergoing nongastrointestinal abdominal surgery.

Objective:To study the relationship between psychosomatic symptoms and psychosocial factors of nursing students in military school.Methods:469 nursing students of a military medical school were investigated by SCL-90,EPQ,PSSS,Coping style inventory and self-esteem scale and so on.Results:Nursing students had lower SCL-90 score than the norm of Chinese female and that of military medical students.Their SCL-90 score correlated with EPQ-E、EPQ-L negatively and EPQ-N、EPQ-P positively.It also correlated with passive coping style positively; with positive coping style,self-esteem negatively.Conclusion:Nursing students of military school have less psychosomatic symptoms than medical students.The influential factors are similar to other populations.

The phenomenon of recessive absence was initiated by many malpractices in current medical educational system.In this article we try to analyze this phenomenon,speculate the subjective and objective reasons,propose countermeasures such as improving teachers quality,reforming traditional teaching mode,strengthening medical ethics education,enriching teaching means and addressing student-centered lectures.

Scientific researchers , medical and nursing staff in Academy of Military Medical Sciences and Chinese PLA General Hospital are the main readers of Medical Library of Chinese PLA.The papers they published in CMCI-covered journals from 2010 to 2012 and their citations were analyzed by citation analysis in order to find the de-mand of users and the use of literature in militarymedical journals , and discover the demand for biological literature information in scientific researchers and nursing staff in Academy of Military Medical Sciences and Chinese PLA General Hospital.The authors proposed that library holding journals should be evaluated with the support rate of highly cited journals and zero citation rate of library holding journals to guide the development of journal resources , provide evidence for the adjustment of resource acquisition , and perfect the library holding resources ofuser-ori-ented demand.

Objective To investigate the therapeutic value of Shuxuetong injection in patients with acute coronary syndrome(ACS).Methods 89 ACS patients were divided randomly into two groups: control group(n =44) and experimental group(n=45).The conventional therapy was used in the control group while Shuxuetong was added in the experimental group.The course of treatment was two weeks.Thromboxane B2(TXB2) and 6-keto-prosta-glandin F1a (6-K-PGF1a) were detected by radio-immunity before and after therapy.Homocysteine were tested by corpuscle enzyme linked immunosorbent assay.Results TXB2 was obviously lower in the experimental group [(554.2±303.2) ng/L] and the control group [(737.2±299.3 ) ng/L ] after treatment than that before treatment (P<0.05).Homocysteine was obviously lower in the experimental group [(10.42±2.99 )μmol/L ] and the control group [(16.39±2.29) μmol/L ] after treatment than that before treatment (P < 0.05 ).6-K-PGF1a was obviously higher in the experimental group[(328.4±99.6) ng/L] and the control group[ (234.5±96.2) ng/L] after treat-ment than that before treatment (P<0.05).TXB2 and homoeysteine in the experimental group were obviously lower than those in the control group after treatment(P<0.05). 6-K-PGF1 a in the experimental group was obviously high-er than those in the control group after treatment (P<0.05).Conclusion Shuxuetong injection could degrade the level of TXB2 and HCY, increase the level of PGF1 a and improve the balance of TXB2/PGF1a, so Shuxuetong is ef-fective in treating acute coronary syndrome.

Objective To investigate the effect of sodium ozagrel injection on hemorheology, endothelin (ET) and nitrogen monoxidum (NO) of patients with non-ST segment elevation myocardial infarction (NSEMI). Methods A total of 81 NSEMI patients were divided randomly into two groups: control group and experimental group. Isosorbide mononitrate, low molecular heparin and simvastatin were administered in the control group while sodium ozagrel was added to the experimental group apart from the above-mentioned drugs. The clinical effect of sodium ozagrel was observed. The changes in the indexes of hemorheology, ET and NO were analyzed. Results The clinical effect was significantly better in the experimental group than in the control group (P<0.05). The level of ET was obviously lower after treatment than that in the experimental group and the control group before treatment (P<0.05). The level of NO was obviously higher after treatment than that in the experimental group and the control group before treatment (P<0.05). The changes of ET and NO in the experimental group post-treatment were more significant than those in the control group after-treatment (P<0.05). The level of hemorheology index after treatment was lower than that before treatment in the experimental group (P<0.05). High-shear rate of whole blood viscosity, platelet adherence rate, and fibrin as hemorheology indexes were lower after-treatment than those pretherapy in the control group (P<0.05). Conclusion Sodium ozagrel injection could affect hemorheology,ET and NO of patients with non-ST segment elevation myocardial infarction. Thefore, the therapeutic efficacy can be better if sodium ozagrel is added to the conventional therapy.
