OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.

METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).

RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.

CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.

OBJECTIVETo study the current status and risk factors of spontaneous abortion of women at reproductive age in rural areas of Shaanxi province.

METHODSPregnant women who lived in Changwu and Bin counties of Shaanxi province were interviewed on their former reproductive history and being followed on the outcomes of pregnancy from 2002 to 2005.

RESULTSThere were 5844 pregnant women under study with a total number of 9638 pregnancies including 1153 spontaneous abortive episodes. Among the pregnant women in rural areas of Shaanxi province, the ratio between spontaneous abortion and pregnancies was 12.0% and the spontaneous abortion rate(SAR) was 13.6%. Ratio between the number of women who had experienced spontaneous abortion and the total number of women under survey was 16.4 %. The risks of having spontaneous abortion would increase among women who were aged > or =30 years and those with more than 3 pregnancies.

CONCLUSIONTo reduce the incidence of spontaneous abortion among rural area women, the approaches should include: strengthening the family planning management, reducing of the frequency of pregnancy, extending the pregnancy interval and avoiding advanced ageing pregnancies.

Objective: To explore the application of grid health education model in improving college students health literacy. Methods: The clustered stratified random sampling method was used among the pre-formative education freshmen in a Xi-an university, with 1 123 students randomly selected totally. The intervention group (578) received health literacy education based on grid health education model, while the control group (545) receuved the original health education model. The effect of gird model of health education on health literacy was compared between two groups of college students after one-semester intervention. Results: Insufficient health literacy was found among freshmen participants in Xi an(17.12%, 17.61%); health literacy on prevention and treatment of chronic diseases (15.92%, 16.70%) was significantly lower than the national average level of urban residents(22.73%). Health literacy of the two groups of college students was significantly improved(47.75%, 27.71%, χ 2=20.50, 5.47, P<0.05). The grid health education model had significant effects in improving health literacy among college students, except for health literacy on safety and emergency(P<0.05). Conclusion Health literacy of college students is insufficient compared to that of urban residents in China. Grid model of health education model is superior to conventional health education model, which is in line with the requirements of health education in colleges in the new era.

Syndrome and formulae (or prescription) are two key issues in traditional Chinese medicine (TCM) and the premise research for material basis of TCM. However, vagueness of syndromes and complexity of formulae greatly limited the evaluation to syndromes and effective substance basis of prescription. Therefore, how to solve the evaluation of syndromes, confirming the efficacy material basis in prescription are the current hot issues of international concern. To solve these problems, establishing chinmedomics by integrated serum pharmacochemistry of TCM with metabolomics technology, that is a unique method of TCM research, made outstanding contributions in solving international concerns such as the effectiveness and security aspects of TCM. On the basis of the biological characterization of syndrome, the metabolic profiling of animal models of TCM syndrome, and related metabolic fingerprints as well as metabolic biomarkers were established to evaluate the overall effects of TCM formulae and corresponding relationship of syndrome-formulae. The active constituents were screened using the plotting of correlation between (endogenous) marker metabolites and (exogenous) serum constituents (PCMS), and is ongoing verification by further biological experiments. Correlation analysis between the ingredients in the body after oral formulae and endogenous markers in vivo can be used to clarify the active ingredients and synergistic properties. This method was successfully applied for rapid discovery of potentially bioactive components and metabolites from TCM, and through a series of studies on the chinmedomics, it proved that the established method could help to explore the effective substance for further research of TCM. As a new research approach, Chinmedomics is the best method to fit the holistic concept of TCM, and it can not only interpret the essence of syndrome but also elucidate the scientific connotation of Chinese medical formulae.
