Objective To summarize the funding of scientific research projects on obstetrics and gynecology by National Natural Science Foundation of China (NSFC) from 2007 to 2016 and to display the hotspots of scientific research on obstetrics and gynecology. Methods A systemic search was performed for the information of projects supported by NSFC from 2007 to 2016. The indicators for analysis included the number of projects, total investment, project categories, research units and research field. The research direction of each project was decided based on title, summary and key words provided by the profile of each project. Results The total investment on obstetrics and gynecology by NSFC was 23.214 million with a total of 82 projects in 2007. It increased year by year and reached the peak in 2014 (359 projects 208.990 million). The investment and number of projects remained stable after 2014. General projects (1109 projects 608.000 million) formed the majority of projects. Youth science fund projects (1035 projects 214.976 million) increased steadily and the number was nearly equal to general projects. There were only a small amount of key projects (20 projects 54.720 million) and major projects (7 projects 38.400 million). The investment varied in different research units. The greatest 10 units (less than 6% of total), including 7 comprehensive universities, 2 medical universities and 1 institute of medicine, got 1113 projects invested (43.84% of total,1113/2539). The hot areas like gynecological tumor (920 projects 350.615 million),hypertensive disorders complicating pregnancy (91 projects 37.470 million) and polycystic ovarian syndrome (77 projects 29.540 million) were more likely to receive investment, while some interdisciplinary science like maternal and child health (28 projects 12.050 million), imaging and biomedicine (37 projects 14.770 million) began to achieve attention in recent years. Conclusions The number of researches invested will be increased for the scientific research in obstetrics and gynecology especially the areas of research focus, although the amount allocated for each will be decreased relatively. Besides, multidisciplinary work will be performed so as to develop obstetrics and gynecology of China to a high level.

Objective To investigate the current status, performance,challenges and demands of the health management service-related institutions in China so as to provide evidence for effective policy-making. Methods A cross-sectional study design was used in this report. The health management service-related institutions were identified based on web site searching and government business registration records. Web or mail-based questionnaire was used for data collection. Telephone interview was conducted to confirm the validity and reliability of the data. Results Of 5744 health management service-related institutions in China,585 were investigated for type of organization, personnel profile, business strategy and investment. Since 2000, the number of health management service-related institutions in China had kept increasing in an average rate of 52%. The services included physical check, health education, and disease intervention,etc. Conclusions In China,health management is still at its early stage although an increasing trend could be found and a large number of related- institutions have emerged. However, health management system in China still faces the challenge of poor professional services and insufficient healthcare providers.

OBJECTIVE:To compare the efficacy and safety of ferrous succinate or Shengxuening in the adjuvant treatment of renal anemia in patients with diabetic nephropathy peritoneal dialysis (CAPD). METHODS:64 diatetic nephropathy CAPD pa-tients with renal anemia were randomly divided into observation group (32 cases) and control group (32 cases). All patients re-ceived subcutaneous injection of insulin for blood glucose control (adjusted the insulin dosage based on fasting blood glucose lev-els),hypertension patients actively controlled blood pressure,corrected acid-base and electrolyte balance disorders,orally received fo-lic acid and vitamin B12,ambulant CAPD,then rhEPO was subcutaneously injected with initial dose of 100-150 U/(kg·week) for 2-3 times and other conventional treatment. Based on it,observation group received 1 g of Shengxuening tablet,3 times a day;control group received 0.2 g Ferrous succinate tablet,3 times a day. The treatment course for both groups was 16 weeks. The rhEPO dose was monthly adjusted to make Hb 100-120 g/L. Clinical efficacy,serum iron,serum ferritin,total iron binding capacity,transfer-rin saturation before and after treatment,Hb,Hct,hs-CRP,rhEPO dose before treatment and after 4,8,12 and 16 weeks of treat-ment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:There was no significant difference in the total effective rate between 2 groups (P>0.05). After treatment,serumiron,total iron binding capacity,transferrin saturation,Hb and Hct in 2 groups were significantly higher than before,and it gradually increased by treatment time,serum ferritin,hs-CRP was sig-nificantly lower than before,and it gradually decreased by treatment time,the differences were statistically significant(P<0.05);but there was no significant difference between 2 groups(P>0.05). The rhRPO dose in observation group 8,16 and 16 weeks af-ter treatment and in control group 8 weeks after treatment were significantly lower than 4 weeks after treatment,and 12 and 16 weeks after treatment in observation group were lower than control group,the differences were statistically significant (P<0.05). The incidence of adverse reactions in observation group was significantly lower than control group,the difference was statistically significant(P<0.05). CONCLUSIONS:Based on conventional treatment,both ferrous succinate and Shengxuening show good ef-ficacy in the adjuvant treatment of renal anemia with diabetic nephropathy CAPD,both can improve anemia and iron metabolism, while Shengxuening is superior to ferrous succinate in terms of improving microinflammatory state and reducing rhEPO dose,with better safety.

Objective:To investigate the feasibility, effectiveness and safety of indocyanine green (ICG) navigation in the surgical resection of abdominal wall endometriosis (AWE).Methods:Seven women undergoing surgery for AWE in First Affiliated Hospital of Sun Yat-sen University (from July 1, 2021 to October 1, 2021) were collected. After exposure of the focus, ICG were used intravenously (0.25 mg/kg) as fluorescent dye for the intraoperative evaluation of AWE vascularization. Resection of the AWE was guided by direct visualization of the focus under standard laparoscopy with a near-infrared (NIR) camera head. Surgical margin around the AWE (3, 6, 9 and 12 point) and the margin under the focus were obtained for postoperative pathological examination of endometriosis. Time from injection to fluorescence visualization, the proportion of fluorescence visualization, time of fully resection of AWE, side effects related to the use of ICG, perioperative complications as well as the pathological result of the surgical margins were recorded.Results:ICG fluorescence of the AWE were seen in 5 patients (5/7). The mean time from injection to fluorescence visualization was (46.7±9.8) s. The mean time of fully resection of AWE was (16.4±7.0) minutes. There were no side effects related to the use of ICG. The rate of class-A wound healing was 7/7. All of the surgical margins were confirmed endometriosis-negative by postoperative pathological examination.Conclusion:ICG fluorescence visualization could conduct accurate resection of AWE, which is clinically safe and effective.

Objective:To evaluate the efficacy and safety of lactulose combined with polyethylene glycol for bowel preparation before colonoscopy in patients of different risks.Methods:A total of 208 patients undergoing colonoscopy were enrolled, including 108 high-risk and 100 low-risk patients. The high-risk patients were divided into group A (54 taking lactulose + polyethylene glycol) and group B (54 taking polyethylene glycol), and the low-risk patients were divided into group C (49 taking lactulose + polyethylene glycol) and group D (51 taking polyethylene glycol). The Boston bowel preparation score, cecal intubation time, withdrawal time, the detection rate of colonic polyps and adenoma, and the incidence of adverse reactions were observed.Results:Among the high-risk patients, the Boston bowel preparation score and adenoma detection rate in group A [(6.35±1.15) scores, 46.3%] were significantly higher than those in group B [(5.76±0.89) scores, 22.2%, both P<0.05], and the first defecation interval in group A was significantly shorter than that in group B [(1.20±0.85) h VS (3.29 ± 2.93) h, P<0.05]. There was no significant difference in adequate bowel preparation rate, polyp detection rate, frequency of defecation or incidence of adverse reactions between group A and B. In the low-risk patients, the first defecation interval in group C was significantly shorter than that in group D [(1.65 ± 1.35) h VS (3.42 ± 2.64) h, P<0.05], and the incidence of adverse reactions was significantly lower than that in group D (44.9% VS 64.7%, P<0.05). There was no significant difference in adequate bowel preparation rate, Boston bowel preparation score, adenoma detection rate, polyp detection rate or frequency of defecation between group C and D. Conclusion:For the high-risk patients, the effect of lactulose combined with polyethylene glycol for bowel cleansing is better than that of traditional polyethylene glycol in the improvement of the Boston bowel preparation score, adenoma detection rate, and the first defecation interval. For low-risk patients, lactulose combined with polyethylene glycol regimen has few advantages over traditional polyethylene glycol regimen.
