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 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 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 summarize the perioperative experience of nursing the middle-aged and elderly patients of lumbar spinal stenosis and degenerative lumbar scoliosis treated with posterior or transforaminal lumbar interbody fusion. Methods Posterior or transforaminal lumbar interbody fusion was performed in 69 middle-aged and elderly patients with lumbar spinal stenosis and degenerative lumbar scoliosis. Nursing measures included evaluation and treatment of complications, preoperative guidance for surgical body position, and postoperative close monitoring, treatment of complications and functional exercises. Results The operation on all the 69 patients was smooth, with surgical time ranged from 3 to 7 hours and bleeding volume between 300~750 mL. Postoperatively, 9 patients suffered from CSF leaks, 3 ones had a screw loose by imageology, 2 did from pneumonia, 2 did from DVT, and 3 did from depression. After clinical management and nursing, all the patients were cured and discharged. Conclusions Meticulous clinical treatment and nursing of preoperative complications and instructions on body position are the foundation for successful surgeries. Postoperatively, close monitoring, management of the complications and the instruction on functional exercises are guarantees for the successful surgeries.

Objective To observe the clinical efficacy of bloodletting cupping plus Chinese medication in treating acne vulgaris due to wind-heat invading Lung Meridian.Method Sixty-six patients with acne vulgaris due to wind-heat invading Lung Meridian were randomized into a treatment group and a control group, 33 cases in each group. The treatment group was intervened by bloodletting cupping at Dazhui (GV 14) and Feishu (BL 13) plus Chinese medication; the control group was intervened by Chinese medication alone. The treatment was given 4 weeks sessions as a treatment course, for a total of 3 courses. The clinical efficacy and relapse rate were compared between the two groups.Result The total effective rate was 74.2% in the treatment group versus 96.9% in the control group, and the between-group difference was statistically significant (P<0.05). Three months after the intervention, the relapse rate was 3.1% in the treatment group versus 16.1% in the control group, and the between-group difference was statistically insignificant (P>0.05); 6 months after the intervention, the relapse rate was 18.8% in the treatment group versus 45.2% in the control group, and the between-group difference was statistically significant (P<0.05).Conclusion Bloodletting cupping plus Chinese medication can produce a more significant efficacy than Chinese medication alone in treating acne vulgaris, with a low long-term relapse rate and fewer adverse effects.

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.
