Objective To evaluate the platelet function in the patients with recurrent spontaneous abortion (RSA) ,to explore the correlations between Hcy and folic acid(FA)with mean platelet volume(MPV) and platelet distribution width(PDW) ,and to evalu-ate the application value of above indicators in predicting RSA .Methods Twenty-eight cases of RSA ,40 cases of healthy pregnancy and 50 healthy child-bearing women(control group) in our hospital were selected .The detection indicators included peripheral blood Hcy ,FA ,PLT ,MPV and PDW .Results The PLT and FA levels in the patients group were significantly lower compared with the normal pregnancy group and control group(P<0 .01) ,while the Hcy ,PDW and MPV were increased(P<0 .05);the various indica-tors had no statistically significant difference between the normal pregnancy group and control group (P>0 .05) .Blood Hcy was negatively correlated with PLT and FA ;Hcy and FA were negatively correlated in the normal pregnancy group ,other indicators had no obvious correlation(P>0 .05) .Conclusion The Hcy metabolism abnormality ,platelet parameter changes and their interactions may be related to RSA .The combined detection of Hcy ,FA and platelet parameters has a certain clinical significance to early diag-nosis and treatment of RSA .

OBJECTIVE： To find out the change of drug resistance of Shigella shigae in our hospital during recent five years.METHODS： To collect the stool of suspectable cases of clinical bacillary dysentery and to carry out bacterial culture and drug sensitive test.RESULTS： The resistance rates of Shingella shigae to ampicillin and fluoroquinolones raised obviously， but the bacilli were still sensitive to amikacine and cefobid.CONCLUSION： It is important to strictly control the indications in using antibiotics and to prevent the emergence of drug resistance of bacteria.

Objective:to study perspective of college students on counseling and psychotherapy Method:440 college students were asked to fill up a mental health knowledge questionnaire made by the authors Result:most of college students attached importance to and had a positive attitude towards counseling and psychotherapy, however they misunderstood some concepts and were not satisfied with the service available Conclusion:counseling and psychotherapy are in the early development stage in China

Objective:To investigate college students' perspective of mental health Method:440 college students were asked to fill up SCL-90 and a mental health knowledge investigation questionnaire made by the authors Result:Most students concerned about their mental health and liked to learn the knowledge of mental health However, there were still some aspects they kept incorrect ideas The results also showed that there were some difference in the attitude toward mental health, as well as the comprehension of the knowledge of mental health between male and female; among freshman, sophomore, junior and senior; between students in different universities, and between students who had visited counselors or psychotherapists and others who had not Conclusion:Pearson correlation analysis showed that college students' knowledge of and attitude to mental health related to their status of mental heath significantly

The scar tissue, resulting from aberrant process of wound healing , can bring about cosmetic deformeties and func-tional limitation, even the displacement of tissues and organs .The widely use of autologous fat graft in regenerative medicine offers a relatively new option for scar treatment .Lipofilling has improved symptoms and appearance of scars in several studies .The application , therapeutic effect and mechanism research of autologous fat graft for scar treatment are summarized in this paper .

Objective: To evaluate the satisfaction degree of non-medical students in medical school,and to investigate the factors that influence satisfaction degree. Method: Selfcompile scale is administered to 430 nonmedical students from 6 medical colleges,in which 5 is in Guangdong province and 1 is in Ha’erbin city. Result:The satisfaction of nonmedical students is low,significant diferences are found between grades,and between students with medicine as the first choice major and those whose first choice major is not medicine. Conclusion:Medical colleges should pay more attention to nonmedical majors,improve the quality of teaching,and so on in order to improve the nonmedical students’satisfaction degree.

Objective To explore the clinical significance of peripheral blood smear and bone marrow examination in the etiological diagnosis of panhematopenia.Methods 180 cases of panhematopenia were selected and were given peripheral blood smear and bone marrow examination,and the results were analyzed.Results There were 50 cases of panhematopenia because of non hematopoietic system diseases.Among 50 cases of non-hematopoietic system disease,there were 20 cases of chronic hepatitis,3 cases of cirrhosis,4 cases of lung cancer,10 cases of malignant tumors,3 cases of endocarditis,7 cases of connective tissue-like illness,1 case of gastric cancer,1 case of systemic lupus erythematosus and 1 case of hypersplenism.Due to diseases of the hematopoietic system,there were 130 cases of panbematopenia.Among 130 cases of panhematopenia due to diseases of the hematopoietic system,there were 74 cases of acute leukemia(AL),13 cases of myelodysplastic syndrome(MDS),13 cases of aplastic anemia(AA) and 30 cases of megaloblastic anemia(MA).Conclusion Peripheral blood smear and bone marrow examination is conducive to diagnose the cause of the panhematopenia.Bone marrow examination could improve the accuracy rate of panhematopenia.

Objective To investigate the relationship between the cerebral blood flow filling condition and prognosis of patients with acute severe cerebral infarction.Methods The clinical data and MR features of 10 cases of acute severe cerebral infarction were retrospectively analyzed.Results The regional cerebral blood flow(rCBF) and regional cerebral blood volume(rCBV) of 9 cases(90%) in the infarcted side decreased significantly.The reduced percents of the infarcted side reached 64.1% and 49.7% respectively.There were significant differences between two opposite sides(P=0.001,P=0.01).The MRA results showed great vessels(arteria carotis interna or arteria cerebri media) in the infarcted side were all obliterated in the all patients,and simultaneous great vessels in opposite side were narrow or occlusion in 7 cases(70%).2 cases died;and 8 cases were serious disability.Conclusions The cerebral blood flow filling of the acute severe cerebral infarction patients decrease significantly.The prognosis of the patients is quite bad.

Polycystic ovary syndrome (PCOS) is a common syndrome in adolescent women and women of reproductive age. Main manifestations are oligomenorrhea, anovulation, polycystic ovarian, and hyperandrogenism with metabolic abnormalities such as dyslipidemia, insulin resistance, and glucose intolerance. PCOS can lead to type 2 diabetes mellitus, cardiovascular diseases, and endometrial cancer, which seriously threat the health of women. The pathogenesis of PCOS is not clear. Over 60% of women with PCOS are obese or overweight. Appetite and energy intake regulation plays an important role in body weight management. Nutrients are mainly digested and absorbed in gastrointestinal track, which is also one of the largest endocrine organs in human body. Special endocrine epithelial cells in stomach, proximal small intestine, and distal small intestine can secrete ghrelin, CCK, GLP-1, and PYY, which involve in the regulation of appetite and are also known as appetite regulating hormones. This review focuses on changes in the secretion of gastrointestinal hormones and related weight loss treatment in patients with PCOS.
