In this paper,the authors reviewed 141 cases of senile gastric carcinoma,with 23 cases followed up.The clinical features,and the relationship between the longth of the course and the resection rate of the tumor have been analysed retrospectively.The results show that gas- tric carcinoma in the aged pepole has a characteristic of a longer history and higher resectable possibility,it is mainly from the canceration of gastric ulcer,well differentiated and low metastatic,and has a favourable prognosis and longer survival.Important suggestions to im- prove its resection rate and survival rate include making a follow-up gastroscopy for the aged pepole with a longer history of gastric diseases or peptic ulcers.For the aged patients who are over 50 with a long history of gastric ulcer or chronic intractable atrophic gastritis,it is rec- ommended to employ the surgery of gastrectomy and the R_Ⅱ mode of operation is of choice, and chemotherapy should be followed.

ObjectiveTo explore the effects of personality characteristics and mental health of students on the career orientation.MethodsThe method of stratified random sampling was used in three universities of Jiangxi province.501 subjects of Arts,Science and Medical Science were tested with Holland career orientation test,symptom check list(SCL-90) and 16 personality factors(16PF).Structure validity analysis,analysis of variance and t -value test were employed with LISREL8.70 and SPSS13.0.Results ( 1 ) The proportion of students choosed the type of occupation were:social type 36％,management type 18％,conventional type 17％,reality type 14％,investigation type 9％,artistic type 6％ ; (2) Career orientation,personality characteristics and mental health had moderate effect on the career orientation.The correlation coefficients of personality characteristics and mental health to the vocational orientation were 0.63 and 0.44.The interaction correlation coefficient was 0.56.ConclusionPersonality characteristics and mental health of college students are important factors to the career orientation and decision-making of job seeking.The personality has stronger explanatory power than mental health.Great emphasis should be paid on both short-term psychological health of college students and long-term cultivation of healthy personality in the employment psychological guidance.

To explore and identify the therapeutic components of traditional Chinese medicine (TCM) as a complex intervention through grounded theory, and the correlation and interaction within this model and the possible effects that they may have on the therapeutic effects of TCM.

Clinical trials play a critical role in medical research. However, only a few clinical trials conducted at present have been registered at various clinical trial registries. Clinical trial registration can prevent bias in these registered trials effectively and avoid unnecessary waste of resources due to meaningless repeats. Moreover, it will benefit the development of evidence-based medicine, and promote human welfare. Great attention has been paid to the importance and necessity of clinical trial registration. This review briefly introduced the definition, justification, contents, history, current status of clinical trial registration, and introduced the information regarding important international clinical trial registries in detail. Clinical trial registration should be developed toward a transparent, compulsory and comprehensive stage.

OBJECTIVE:To investigate the effect of mixing herbal injections with transfusion fluid on production of insoluble particles.METHODS:To detect the amount of insoluble particles before and after mixing herbal injections with transfusion fluid with ZWF-4 particule counter.RESULTS:The insoluble particles increased obviously.CONCLUSION:It should be paid great attention to the increase of insoluble particles after mixing,as well as the relationship between the insoluble particles and adverse reactions.

The controlling system of triple pulse vacuum sterilizer for dental use adopts PIC single-chip computer as the controller. The information related to stream temperature and pressure of the stream and liquid mixture in the hermetic vessel is acquired and controlled. Linearization measurements of the temperature and pressure and fuzzy control technology are all involved in. The experiment result shows that the controlling system makes the sterilizer free from overshoot, steady-state error and non-robustness.

Objective To study the influence of progesterone (PROG) on infarct volume and functional outcome and to evaluate the therapeutic value of PROG on cerebral infarction in rats.Methods Health adult male Sprague-Dawley rats were randomly divided into sham-operated (control) group,ischemic group,vehicle-treated group and PROG-treated group.Permanent cerebral ischemia was induced by occlusion of the left middle cerebral artery (MCA) using an intraluminal filament technique.Sham-operated rats were subjected to the same surgical procedure,except that the filament was not advanced to occlude the MCA.Progesterone or 2-hydroxypropyl-β-cyclodextrin was injected intraperitoneally following permanent middle cerebral artery occlusion (PMCAO) of rats.Zea Longa test was used to evaluate their functional outcome at 1d,2d,3d after stroke.TTC staining was used to detect the infarct volume at 3d after stroke.Results The results of Zea Longa test showed that there were no functional deficits in all animals prior to ischemia.There were no significant changes in motor function in sham-operated animals across the 3 days assessment period.Both PROG and vehicle-treated rats experienced significant decline in scores following occlusion.However,PROG-treated rats (3.00 ± 0.63,2.83 ± 0.75,2.00 ± 0.89 )demonstrated a gradual improvement in scores compared with ischemic (4.00 ± 0.89,3.83 ± 0.75,3.16 ± 0.75 )and vehicle-treated rats ( 3.67 ± 1.21,3.50 ± 1.05,2.83 ± 0.76) at different times (P ＜ 0.05 ).TTC staining revealed that PROG administration significantly reduced the total infarct volume in the PROG-treated rats ( ( 15.03± 3.75) ％ ) compared with ischemic ( (23.74 ± 4.48 ) ％ ) and vehicle-treated rats ( ( 24.42 ± 7.07 ) ％,P ＜0.05).Conclusions PROG significantly reduces infarct volume and promotes the recovery of neurological functions after pMCAO,which has good therapeutic value for the rat model of cerebral infarction.

Polysaccharide in Patrinia scabra Bunge. was determined by spectrophotometry at 490nm,with phenol-concentrated suIfuric acid as the color developer. The content of polysaccharide was found to be 1. 50%

Objective:To investigate the neuroendocrine properties of adrenalcortical tumors.Methods: We retrospectively reviewed the clinical data of 99 adrenalcortical tumor patients,who were treated in Changzheng Hospital form June 1999 to June 2005.Expression of neuron specific enolase(NSE),chromogranin A(CgA) and synaptophysin(Syn) proteins were examined by immunohistochemistry(S-P method) using monoclonal antibodies.The general data of patients,including the age,symptoms,laboratory findings,and pathological types,were collected and subjected to statistical analysis with SAS v6.12 software.Results: The expression of all the above 3 proteins was found in adrenalcortical adenoma tissues,with the positive rate of NSE being 80%,the positive rate of CgA being 48.9%,and the positive rate of Syn being 75.6%;the positive rates in the adrenalcortical carcinoma tissues were 77.8%,22.2%,and 77.8%,respectively;and those in the normal adrenal tissues was 20%,0%,and 10%,respectively.The positive rates of 3 proteins in adrenalcortical tumors was significantly higher than those in the normal adrenal tissues(P

Objective To evaluate the efficiency, safety and complications of transcatheter closure of atrial septal defect (ASD) using Amplatzer and sideris occluder under the guidance of transthoracic echocardiography and fluoroscopy. Methods Fourteen patients of ASD, 6 male and 8 female, age ranged from 2.6 to 43 years old, were treated by transcatheter closure of ASD with Sideris or Amplatzer occluders. All cases were guided by thansthoracic echocardiography and fluoroscopy. Results The diameter of ASD (balloon stretched diameter) was 14-34 mm (24.16 ? 5.16)mm. The Amplatzer devices were used in 9 cases, all of them were successfully occluded with satisfactory results. Of 5 patients treated by Sideris buttoned devices, 4 had success procedure and one failed, in which unbuttoning occurred and retrieval of the device was performed by emergency surgery. Conclusion Transcatheter closure of ASD is a simple and convenient method with a high success rate and reliable curative effect. The indication of Amplatzer method is much wider and the instant success rate after the procedure is much higher than those of Sideris device. Thansthoracic echocardiography plays a key role for guiding transcatheter closure of ASD in this study.
