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 The loss of NF2 gene in cutaneous schwannomas of neurofibromatosis type 2 patients was investigated in order to explore the tumorigenesis and characteristics of NF2 tumor suppressor gene, and to provide evidence for presymptomatic gene diagnosis for NF2 patients. Methods DNA was extracted from whole blood and frozen tumor tissue, respectively. Genotyping was performed using 6 microsatellite markers flanking or within the NF2 gene: CRYB2－ D22S193－ NF2CA1－ NF2CA3－ D22S268－ D22S430, which is tightly linked to the NF2 gene and analyzed on an ABI Genetic Analyzer 310 after PCR amplification. Results A total of 18,14,0,13,16,12 samples showed loss of heterozygosity at microsatellite markers CRYB2， D22S193， NF2CA1， NF2CA3， D22S268， D22S430 in 43 samples of cutaneous schwannomas, respectively. Conclusions The method for detection of NF2 allelic loss was established. Frequent allelic loss reconfirms that NF2 gene is a tumor suppressor gene. The observation that tumors with or without allelic loss of the NF2 gene exist in the same patient indicates that these tumors are originated from different clones in which genetic alterations occurred independently.

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 evaluate the feasibility and efficacy of Separate stent placement in the palliative treatment of inoperable malignant gastroduodenal obstruction.Methods Thirty four consecutive patients with inoperable malignant gastroduoenal obstruction were treated with peroral placement of Separate stent. Gastroduodenal obstruction was caused by gastric ( n =11), pancreatic ( n =12), matastatic ( n =3), biliary duct ( n =6) or duodenal ( n =2) cancers. Separate outer partial covered stent overlapping with inner bare stent were placed coaxially under fluoroscopic guidance.Results The technical successful rate reached 97% (33 of 34) with no major complication. Symptoms of gastroduodenal obstruction relieved in 33 patients. The average score of food intake capacity improved from 3.8 to 1.2 after Separate stent placment. Stent migration and tumor ingrowth were not detected during the follow up period. Tumor overgrowth was confirmed in one patient and a second stent was placed to solve the problem.Conclusions Peroral placement of Separate stent is a feasible and effective treatment for patients with inoperable malignant gastroduodenal obstruction.
