Methods A total of 16 PCOS patients who had no response to ovulation-inductive therapy were treated by ovarian electrocautery via laparoscope. After surgery, the ovulation as well as response to ovulation-inductive drugs was observed. The serum concentrations of FSH, LH, T, E 2 before and after operations were respectively compared. Results All 16 cases were pathologically diagnosed as polycystic ovary. There were significant decreases in luteinizing hormone (LH) and testosterone (T) after operations (P

BACKGROUND: Heal-all oral biofilm is a material utilized in repairing oral mucosa and soft tissues defects and characterized by degradation, easily preparation, long preserved duration, convenient transportation and good ossification, which has been widely used in dental implant as guided bone regeneration materials.OBJECTIVE: To check the clinical effective of Heal-all oral biofllm on guided bone regeneration in dental implant.METHODS: A total of 72 patients with bone defects in the implantation area were selected as subjects, who were divided into control group and experimental group at random. Bone defects around implants were repaired by guided bone regeneration technique with BME-10X medical collagen membrane and Heal-all oral biofilm respectively. X-ray and clinical examination were taken at 1 and 3 months after implantation. The amount of new.formed bone tissue was evaluated when stage Ⅱ operation was performed.RESULTS AND CONCLUSION: In stage Ⅱ operation, osseointegration was formed between implants and bone tissue in all 72 patients. The average rate of bone formation was 92% in the experimental group while 91% in the control group. All implants were successfully repaired with implant denture. Occlusal function was restored successfully with all 72 implants during the follow-up period of 3-24 months after restoration. As an alternative option of BME-10X medical collagen membrane, Heal-all oral biofilm can be used in guided bone formation clinically.

Objective To identify the quality of life (QOL)and major influencing factors for migrant workers in Zhejiang province.Methods The QOL of 1217 migrant workers and 1387 permanent urban residents in Zhejiang province were measured by WHOQOL-BREF scale (Chinese version)in a stratified sampling.A multiple linear regression model was used to analyze the relationship between the factors and the scores of the four domains.Results There were no significant statistical differences(P＞0.05)found in the scores of physical health,social relationship and general health between migrant workers and urban residents.Their scores of psychological health,surrounding conditions and general quality of life,however,were found lower than urban residents (3.5 ± 0.8 vs 3.6 ± 0.8).Influencing factors for their psychology were education,family conflicts and appetite; those for their surrounding conditions were daily average work hours and appetite.Conclusion Given improvements in the quality of life of migrant workers,rooms to improve were found in such scores as psychological health and surrounding conditions.

Objective To observe the changes of pulmonary function parameters in healthy middle-aged and elderly people in Shanghai.Methods A total of 298 subjects aged 45 years and over with normal pulmonary function and no smoking history were selected among subjects who underwent routine physical examination from Jun 2009 to Sep 2011.The subjects were divided into three groups:45-59 years,60-69 years,and ≥70 years.The tested pulmonary function included 13 parameters:vital capacity (VC),residual volume (RV),functional residual capacity (FRC),total lung capacity (TLC),RV/TLC,forced vital capacity (FVC),forced expiratory volume in one second (FEV1),FEV1/FVC,peak expiratory flow (PEF),forced expiratory flow at 25 ％ of FVC exhaled (FEF25),forced expiratory flow at 50％ of FVC exhaled (FEF50),diffusion capacity of the lung for carbon monoxide (DLCO),and specific diffusion capacity of CO (KCO).Results Compared with the young adults,7 pulmonary function parameters including VC,FVC,FEV1,PEF,TLC,DLCO and KCO were declined significantly in healthy middle aged and elderly people Compared with the young adults,pulmonary function parameters including RV and RV/TLC were increased [male (1.9 ±0.4)Lvs.(1.6±0.3)L,(34.7±4.9)％ vs.(26.4±4.3)％,P＜0.01;female (1.5±0.3)L vs.(1.3±0.3)L,(36.1±5.3)％ vs.(30.3±5.5)％,P＜0.01].Although RVincreased with aging in middle-aged and elderly people,but there was no statistical significance (P＞0.05).FRC didn't change obviously.FEV1/FVC was lower in old people than in young people[male (80.7±4.3)％ vs.(84.2±5.6)％,P ＜0.01;female (82.5± 5.5) ％ vs.(86.4±4.8)％,P＜0.01],but the difference between 3 groups of middle-aged and the elderly was not significant.The FEV1/FVC of men and women aged 70 and more were (80.2±4.5)％ and (81.8±5.6)％,respectively.Conclusions Both ventilation function and diffusion function of healthy elderly people are decreased with ageing,RV is increased and FRC is steady,and the declining tendency of FEV1/FVC obviously slows down with aging in middle aged and elderly people.

OBJECTIVE: To optimize the preparation process of Xiangsha Liujun Granule. METHODS: By the orthogonal design. taking the rates of recovery of volatile oil, Ginsenoside Re and qualified granules as the indexes, we optimized the oil extracting conditions, the decocting conditions and the conditions of granulation by spayer. RESULTS: The optimum oil ex- tracting conditions for four kinds of herbs(Pericarpium Citri Reticulatae etc.) were that water was 30 times of herbs in weight, soaking time was 3 hours and extracting time 15 hours. The optimum decocting conditions for four kinds of herbs(Fuling etc.) were that water was 15 times of herbs in weight, soaking time was 3 hours and decocting time 4 hours, herbs were decocted twice. The optimum conditions of granulation by sprayer were that the fliud extract was 2 times of Dextrin in weight, the rel- ative density of the fliud extract was 1. 30(measured at 25℃), the voltage of sprayer was 120 volts, the period of shaking bag was 65 times(shaking bag back and forth twice in each period). CONCLUSION: The results of the experiment make it clear that the preparation process of Xiangsha Liu jun Granule is stable and feasible.

Isometric exercise(IE) is an essential component of daily living activities.Lack of IE may result in deconditioning of IE capacity.IE has not been used in cardiac rehabilitation because of poor understanding in cardiovascular response to IE and the Valsalva Maneuver associated with IE.Eingteen healthy young subjects aged 23.7 yrs on average was studied by administration of beta blocker and antagonist of opioids during IE.The result demonstrated that the regulation of cardiovasular response during IE is attributed to both sympathetic system and opioids activity.Twenty patients with coronary artery disease (CAD) were also studied during brief maximal IE,sustained maximal IE and dynamic exercise(DE).The patients included 13 cases with more than one vessel lesions and 7 post myocardial infarction and/or angina.Ten age matched apparent healthy subjects were examined as the control group.The result showed that IE without the Valsalva Maneuver in patients with CAD might increase coronary artery perfusion by enhancing diastolic pressure and prolonging diastolic period,which had no harmful effect on CAD.Hemodynamic responses and cardiac function were weaker during IE than DE.The intensity of the responses to IE was correlated to the central command but not to the absolute work load.It is concluded that significant release of endogenous opioids due to strong central command during IE,especially perceived maximal sustained IE,may help to attenuate activity of sympathetic system,thus reducing risk of exercise in patients with CAD.

BACKGROUND: Peri-implant crestal bone resorption is considered as a normal reaction according to traditional butt-joint prosthesis around two-piece implants. OBJECTIVE: To evaluate bone loss around two-piece implants restored according to the platform switching concept in the posterior area of the mandible. METHODS: Eighty-eight implants were consecutively placed in 50 patients following submerged surgical protocol. In the test group, 40 Ankylos implants were placed using platform switching technique, while 48 3i implants using traditional butt-joint in the control group. All the implants were positioned at the crestal level. Definitive prosthesis was delivered after 3 months. RESULTS AND CONCLUSION: All implants were judged to be successfully osseointegrated. The success rate was 100%. Twelve months after restoration, radiographic analysis showed an average bone reduction level of (0.31±0.39) mm in the test group that was statistically significantly different (P < 0.01) from the average reduction in the control group [(0.94±0.43) mm]. In the follow-up time, no implants were loose or lost and healthy gingival was seen. These findings show that the platform switching technique can reduce peri-implant crestal bone resorption and preserve alveolar bone level around dental implants 12 months after restoration.Oral Implantology Center, Affiliated Hospital of Medical College, Qingdao University, Qingdao 266003, Shandong Province, China

Objective To evaluate the mental status of malignant hematologic patients, explore the morbidity of depression in malignant hematologic patients, and investigate valid interventional treatment on them. Methods 134 malignant hematologic patients were evaluated by SDS and HAMD, and 49 patientswere selected who was diagnosed depressive disorder then randomly divided into 2 groups. One was experimental group and the other control group. The patients of experimental group were treated with antidepressant drug and mental intervention during common therapy, while the patients of control group only took common therapy. The change of immunological function after treatment was detected. Results The morbidity of depression in malignant hematologic patients was 37 %. The scores of SDS and HAMD were significandy decreased and the depressive symptoms were notablely improved in experimental group and there were significant differences after treatment and before treatment (P <0.01), but there was no significant difference in control group (P >0.1). The NPY plasma levels significantly increased after treatment in experimental group(P <0.01), but there was no significant difference in control group(P >0.05); the CD+4/CD+4 values of patients in the experimental group were significantly increased after treatments. Statistical analysis revealed significant differences in the experimental group patients between pre-treat and after-treat (P <0,05),but no obvious difference in the patients of control group (P>0.5). Conclusion Mental intervention and antidepressive treatment can improve all of the depression, immunological function and quality of life of malignant hematologic patients.
