Objective To study the relationship between serum adiponectin and insulin resistance in wo men with polycystic ovary syndrome(PCOS). Methods Forty women with PCOS and twenty five healthy women were divided into PCOS obese group [body weight index(BMI)≥25kg/m 2], PCOS non-obese group(BMI

Objective To evaluate urgent selective arterial embolization to treat massive postpartum hemorrhage. Methods Twenty seven patients with ages of 21～53 years undengoing severe postpartunm hemorrhage, were due to centrol placenta previa, uterine atony, birth canal trauma, placenta accretio, cervical pregnancy etc. All of the patients had lost a volume of blood about 1 000ml to 5 000ml while the hemorrhage could not be controlled with vaginal packing and administration of uterotonic drugs. Urgent hemostatic embolization was performed for them. After angiography, super selective catheterization was performed for bilateal anterior division of internal iliac branch of uterine arteries and embolized with Gelfoam particles. Results Catheterization success rate was 96.3%. Angiography showed ectopic uterine artery in one case. Immediate block of hemorrhage took place in 22 cases and gradual hemostasis appeared in 4 cases, the efficacy rate was 96.3%. The one with ectopic uterine artery was operated upon to ablate the uterus. 11 patients with (bleeding) shock and 8 patients with DIC were all saved. Conclusions Urgent arterial embolization is an ideal method for treating life threatening postpartum hemorrhage. The procedure saves the maternal uterus and is also effective for postpartum DIC.

The General Rules of the Civil Law of the People′s Republic of China(hereinafter the General Rules)shall officially come into effect as of July 1 of 2017.In this consideration,the paper probed into the legal attributes of the doctor-patient relationship in China in view of the relationship management in line with the General Rules.Also analyzed are the basic principles to be observed by both parties as regulated by the General Rules and patient rights protection.These efforts aim at elevating China′s medical service,protecting legitimate rights of both parties,and encourage a healthy and harmonious doctor-patient relationship.

Objective To compare the clinical efficacy and safety between the improved ligation method and the traditional ligation method in the treatment of internal hemorrhoid. Methods Double blind and randomized study were made in 86 patients with internal hemorrhoid. The traditional method was performed by ligation of internal hemorrhoidal body, and the improved method was to ligate rectal mucous membrane above internal hemorrhoidal radicles. Results The improved method has better effect than the traditional method. The clinical symptoms of internal hemorrhoid such as bleeding,pain,constipation,edema,itching and erosion in the patients treated by the improved method were significantly improved compared with the patients treated by the traditional method(P

Objective To study the effects of formaldehyde on activities of enzymes in testes of male mice. Methods Male Kunming mice were used. Experimental groups had been exposed to formaldehyde with different doses by i.p. once per day for 7 consecutive days. The formaldehyde doses were 0.2, 2.0 and 20.0 mg/kg body weight. The mice were killed after 7 days of treatment and their testes were fetched out to be made into even slurry and the activities of LDH, G-6-PD and SDH in them were tested. Results The activities of G-6-PD and SDH were decreased with the increasing of doses of formaldehyde. Compared with the control group, the activities of SDH in each exposed group had significantly decreased (P

The authors analyzed current situation of teachers'professional development in medical colleges and universities. The construction of teachers'professional development systems includes dividing the stage of development and setting the standard,constructing teachers'evaluation model,constructing interscholastic and scholastic teachers'education pattern,enriching the training contents and diversifying the training ways.

Objective Fluctuation of glucose levels is more likely to cause oxidative stress which contributes to the development of insulin resistance through activating c-Jun N-terminal kinase (JNK).Such antio xidants as vitamin C or vitamin E do not appear very helpful.Radix Astragali (RA) is an herbal medicine with antioxidative ability.The study was to explore whether RA would lower the risk of insulin resistance in diabetic rats.Methods Diabetic rats received RA,insulin or both RA and insulin after diabetes were induced in male Wistar rats.Serum levels of interleukin 6 (IL-6) and tumor necrosis factor α (TNFα),advanced glycation endproducts(AGEs) levels in kidney,the expression of insulin receptor (IR),insulin receptor substrate 1 (IRS-1),p38 mitogen-activated protein kinase (MAPK),p-p38 MAPK,p-JNK,p-IRS-1 Ser307,and p-IRS-1 Tyr612 in skeletal muscles were determined.Results Compared to diabetic rats treated with insulin,the diabetic rats treated with both insulin and RA demonstrated significantly lower levels of IL-6,TNF-α and AGEs (P ＜ 0.05),significantly lower activation of p-p38 MAPK and JNK (P ＜0.05),significantly higher expressions of IRS-1 (P ＜0.05),p-IRS-1 Tyr612,and significantly lower expression of p-IRS-1 Ser307 (P ＜ 0.05).Conclusions RA can lower the risk of insulin resistance through fighting oxidative stress in diabetic rats.

Three kinds of fortified biscuits and bread were given as breakfast for 5 months to 106 preschool children 4-6 years old lodged in a kindergarten, with a control group taking common biscuits and bread without fortification. 6 g protein and 160 kcal were supplied by 50 g of fortifed foods in which 0.25 g lysine, 0.25 g lysine and 0.8 mg riboflavin, and cod liver oil and calcium in addition to lysine and riboflavin were fortified respectively. The results showed that a diet with intake of 2.1 g protein and 71 kcal/kg body weight fortified on the average by 228 mg lysine or 228 mg lysine and 1.1 mg riboflavin increased the monthly increment of body weights, heights, and urinary excretions of creatinine per day. There was also a tendency of improvement, in nitrogen retention. The urinary excretion of riboflavin in load test was increased in the group taking the second kind of fortified foods.

Fifty-four children, aged 1.5-3.5 years, were selected from a nursery and divided into three groups. To the children in group 1 multivitamin fortified formular milk powder of Hai-He brand (70g daily) was given as a supplementary food in addition to the normal diet and whole milk powder of Hai-He brand was given to group 2 as another supplementary food. The third group served as control. This observation was lasted for three months. At the end of the third month, the increments of body weight of the children, tricep skinfold and circumference of upper arm of group 1 were higher than those of group 3 significantly, but there were no significant differences between group 1 and group 2. The hemoglobin content of group 1 increased by 0.8g/dl but group 2 and 3 decreased by 0.53g/dl and 0.72g/dl respectively. At the end of our observation, the concentrations of vitamin B1, C and PP in urine of group 1 were higher than those of other two groups by vitamin load test.Thus, we may consider that the multivitamin fortified milk powder is better than the whole milk powder in improving the vitamin and iron nutritional status of young children.

Objective To compare the clinical efficacy and safety of two different conditioning regimens in nonmyeloablative autologous peripheral blood stem cell transplantation (NAST) for the treatment of systemic lupus erythematosus (SLE).Methods Different conditioning regimens were used in two groups:cytarabin combined cyclophosphamide in group 1 and ATG combined cyclophosphamide in group 2.Different recovery time of leucocytes,neutrophils and platelets in the two groups were compared.Statistical analysis were carried out by paired t-test.Results The mean time for peripheral leucocytes reaching 1.0×109/L,neutrophils getting up to 0.5×109/L,platelet raising to 100×l09/L and hemoglobin rising to 120 g/L in group 1 were [(7.2±1.3),(8.0±1.5),(10.5±1.4),(22.1±2.3)days] and [(10.4±2.1),(12.0±1.9),(19.3±2.1),(28.1± 2.4)] days in group 2.The difference was statistically significant (P＜0.01).CD4+ cell count and the ratio of CD4+/CD8+ of pre- and pro-NAST was changed.No significant differences were observed in the two groups.Conclusion For the sake of safety and hematopoietic reconstitution,we recommend cytarabin combined cyclophosphamide as the preferred conditioning regimen.
