Objective To observe the clinical efficacy of herbs by internal and external administration combined with semiconductor laser irradiation in the treatment of chronic eczema.Methods Eighty-six patients with chronic eczema were divided into the herb group and the laser group by the randomized digital table,43 patients in each group.The patients in the herb group received oral administration with Chinese herbs together with application of herbs on the affected foci.The patients in the laser group received the same treatment as in the herb group and meanwhile treated with additional semiconductor laser therapy.The clinical effects were evaluated according to their itch degree and skin lesions.Result The cure rate and total effective rate were both significantly higher in the laser group than those in the herb group(P<0.05).Conclusion Compared with herbal internal and external administration only,the clinical efficacy of herbal internal and external administration combined with semiconductor laser irradiation is more effective in the treatment of chronic eczema.

Objective To analyze the clinical application of detecting anti Mullerian hormone (AMH) in the patients with polycystic ovary syndrome (PCOS).Methods A total of 480 cases with PCOS and 500 cases of healthy females were selected in the study.The levels of AMH in the patients with PCOS were compared between the two groups.Results The levels of AMH,luteinizing hormone (LH),testosterone (T) in patients with PCOS were significantly higher than those in the healthy control group (P＜0.05).Differences of the levels of estradiol (E2) and follicle-stimulating hormone (FSH) in patients with PCOS and thosein healthy control group had no statistical significance(P＞0.05).As the age increased,the level of AM H obviously declined.Conclusion The level of AMH in patients with PCOS is obviously higher than that in the healthy ones,it declines with the age increasing.

Objective To analyse the effects of Word Bank Loan Schistosomiasis Control Project in Hunan Province from 1992 to 2000. Methods The administrative villages in Hunan endemic areas were divided into heavy, moderate and low zones respectively, based on human infection rates. Control strategies including a major approach of chemotherapy to inhabitants and bovines with praziquantel, complemented with health education as well as snail control by environment modification, were adopted in each endemic zone. Schistosomiasis prevalence surveillance was carried out in 50 moving pilots selected from endemic villages in each zone every year. Results At the beginning of the programm, there were total of 35 endemic counties (cities, districts, farms) and 471 endemic towns in Hunan Province. Up to 2000, 8 endemic counties (farms) reach the transmission interruption criteria, and 25 counties and 300 towns reach the transmission control criteria. Heavy endemic villages decreased from 762 to 271, while moderate endemic villages from 1728 to 1053, and low endemic villages increased from 1447 to 2716. Human infection rates dropped from 11.59% to 5.64%. Conclusion The schistosomiasis epidemic situation decreased obviously after implementing the project in Hunan Province.

Objective To study the effects of two different methods of high-pressure injections on imaging quality of synchronous left axillary artery and vein by using volume CT.Methods Forty seven patients who underwent left axillary vein and artery CTA examination study were analyzed retrospectively according to the contrast agent injection scheme and was divided into two groups A and B.Group A of 25 patients used protocol A,adopted clinical routine delay scanning method,via right elbow vein inject contrast medium.Group B of 22 patients used protocol B,adopted artery delayed imaging combined with vein direct imaging method,via right elbow vein,left radial vein inject contrast agent,respectively.Both values of CT and contrast to noise ratio (CNR) of two groups were compared,objective image quality was compared by two blinded readers.Mann Whiteny U test was used.Results The median of CT values for left axillary artery in group A was 151.9 HU.The median of CNR values for left axillary artery in group A was 7.4.The median of CT values for left axillary vein in group A was 116.0 HU.The median of CNR values for left axillary vein in group A was 3.83.The median of CT values for left axillary artery in group B was 348.8 HU.The median of CNR values for left axillary artery in group B was 25.3.The median of CT values for left axillary vein in group B was 497.0 HU.The median of CNR values for left axillary vein in group B was 35.4.Both values of CT and CNR in two groups showed significant difference (Z=-5.735,-5.799,-5.863 and-5.863,P＜0.01).All of the median scores in group B were greater than in group A(P＜0.01).Conclusion The enhancement effect of protocol B in the left axillary arteriovenous synchronous imaging is significantly higher than those of protocol A,and demonstrates clear image quality and clearer anatomic relationship.

Objective To explore the efficiency of continuous glucose monitoring system(CGMS) and blood glucose self-monitoring (SMBG)in evaluating blood glucose excursion in type 1 diabetes mellitus (T1DM) complicated with pregnancy. Methods Twenty-five patients having suffered from T1DM complicated with pregnancy were selected randomly during June 2012 to July 2015. All subjects underwent blood glucose monitoring by CGMS and SMBG for 72 h, including the data of blood glucose before meal, 2 h post-meal blood glucose (2hBG) and blood glucose at 2:00 AM. Results The level of the highest blood glucose in CGMS was significantly higher than that in SMBG:(10.60 ± 2.11) mmol/L vs. (7.50 ± 1.18) mmol/L, P<0.01. The level of the lowest blood glucose in CGMS was significantly lower than that in SMBG:(3.60 ± 1.06) mmol/L vs. (4.50 ± 1.15) mmol/L, P<0.01. The level of mean blood glucose in CGMS and SMBG had no significant difference:(7.20 ± 1.18) mmol/L vs. (7.30 ± 1.15) mmol/L, P>0.05. The rate of hypoglycemia(blood glucose<3.3 mmol/L) in CGMS was 4.6%, and in SMBG was 1.9%. Through adjusting the treatment by CGMS, the blood glucose before meal, 2hBG and blood glucose at 2:00 AM at 49-72 h were significantly lower than that at 0-24 h (P<0.05). Conclusions Compared with SMBG, CGMS has a relatively larger blood glucose monitoring range and can sensitively evaluate blood glucose excursion, CGMS provides a scientific basis to develop a more rational and effective strategies for controlling diabetes.
