Objective To analyze the effect and safety of different doses of mifepristone treating perimenopa-usal dysfunctional uterine bleeding.Methods 80 patients with perimenopausal dysfunctional uterine bleeding were collected.According to the medicine of 5,10mg,25mg mg doses,80 cases were divided into the low dose group (n=26),middle dose group (n=26) and high dose group (n=28).The treatment results,endometrial thickness change, sex hormone level change and the adverse reaction were observed after 3 months.Results In terms of treatment effect,the effective rate in the middle dose group (92.3%) and high dose group (82.1%) were better than that of the low dose group(61.5%)(F=3.98,P<0.05);The inhibitory effect of endometrium in the middle dose group and high dose group were superior to the low dose group( F=4.34,P<0.05);All three groups of sex hormone level was significantly lower in the body;Middle and high dose group of the adverse reactions of treatment process was more,the adverse reaction happening far higher than that of the low dose and dose group (F=3.97,P<0.05). Conclusion 10mg mifepristone in the treatment of perimenopausal dysfunctional uterine bleeding has good effect, less adverse reactions,which is worthy of clinical application.

Objective To observe and evaluate the healing effect of medical skin collagen regeneration func-tional dressing on facial dermatitis.Methods 40 facial dermatitis patients who met the inclusion criteria were ran-domly divided into the observation group(group A)and control group(group B)averagely.Patients of group A were administrated with ketotifen tablets orally and with medical skin collagen regeneration functional dressing externally,while patients of group B were only orally administrated with ketotifen tablets.The total observation period last 15 days with a follow -up once after 2 days for both of the groups.Results The cure rates of group A after 12 day and 15 day were 63.2% and 65%,higher than the cure rates of group B(5.0% and 5.0%).The 12 day and 15 day cure rates of group A were significantly higher than those of group B(χ2 =14.83,15.82,all P <0.01).Conclusion Medical skin collagen regeneration dressing in combination with fexofenadine tablets provide a safe and effective healing func-tion to facial dermatitis.

Objective To determine the endothelial function, endothelin-converting enzyme (ECE) activity and ECE mRNA level in patients of diabetes with macroangiopathy, and to investigate the effect of the endothelial function change in type 2 diabetes and diabetes with macroangiopathy. Methods Sixty healthy persons and 40 patients of type 2 diabetes and 60 patients of type 2 diabetes with macroangiopathy were recruited for the study. The activity of ECE in white blood cells was measured by an established method. Endothelial function, ECE activity and expression of ECE mRNA were determined by ELISA, RIA and RT-PCR respectively. Results The expression of ECE mRNA and the ECE activity were increased in patients of type 2 diabetes, especially in diabetics with macroangiopathy. The damage of endothelial function in the diabetic patients was very common. Conclusion High level of ECE activity relates to the damage of endothelial function. High level of ECE activity and up-regulation of expression of ECE mRNA may play a key role in the development of diabetic macroangiopathy.

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 explore the mechanism of intrauterine growth restriction (IUGR) via observing the change of mitochondria in IUGR placenta. Methods Placenta samples were collected from 30 singleton pregnancies at the time of elec-tive caesarean section. Fifteen of them were appropriate for gestational age and 15 were IUGR. Mitochondrial morphology was observed by transmission electron microscopy, DNA copies were analyzed by real-time quantitative PCR and membrane potential was assayed by lfow cytometry. Results Signiifcant morphological changes of placental mitochondria were observed under transmission electron microscopy in IUGR, mitochondrial DNA copies in IUGR placenta were signiifcantly increased (P<0.01) and membrane potential decreased dramatically (P<0.01). Conclusions It is suggest that impaired mitochondrial function in IUGR may involve in IUGR pathogenesis.

Objective To explore the influence of middle cerebral artery blood flow on mechanical ventilation in very low birth weight premature after using Budesonide(BUD) mixed with pulmonary surfactant(PS),and to explore the protection mechanism of cerebral injury.Methods Forty premature infants (gestational age ＜ 34 weeks,birth weight ＜ 1 500 g) with respiratory distress syndrome(RDS) were randomly assigned into study group and control group in Nanjing Maternal and Child Health Hospital from Aug.2010 to Mar.2012.PS and BUD mixture was used in study group (Per 70 mg PS adding BUD 0.25 mg),PS dose of 70 mg/kg,BUD dose of 0.25 mg/kg.Control group was only administered with PS,dose 70 mg/kg.It was administered intratracheally after 30 to 60 minutes of birth in both groups.The index of blood flow rate and blood vessel elasticity of arteria cerebri media [including systolic velocity (Vs),diastolic velocity (Vd),mean velocity (Vm),resistant index (RI) and elasticity index (PI)] were monitored by using transcranial Doppler.Results The Vs increased steadily in study group,but instability in control group,and there were of statistical differences on the 4 d,5 d,6 d and 7 d (t =3.21,2.95,3.12,3.43,all P ＜ 0.05).The Vd increased steadily in study group,but unsteadily in control group,and there were statistical differences on the 4 d,5 d,6 d and 7 d (t =4.21,3.10,3.98,4.56,all P ＜0.05).The Vm of study group was higher than that in the PS group,and there were statistical differences on the 4 d,5 d,6 d and 7 d (t =2.68,2.98,3.98,3.57,all P ＜ 0.05).The RI of study group was higher than that in the control group,and there were statistical differences in the 5 d,6 d and 7 d(t =3.10,3.98,4.06,all P ＜ 0.05).PI steadily in study group,but instability in control group,and there were statistical differences in the 5 d,6 d and 7 d (t =4.18,3.23,3.02,all P ＜ 0.05).The overall incidence of periventricular/intraventricular hemorrhage showed no significant difference,but severe periventricular/intraventricular hemorrhage (grade Ⅲ,Ⅳ) of study group was less than that in the control group (x2 =4.80,P ＜ 0.05).The incidence of periventricular leukomalacia was reduced in the study group compared with that in the control group (x2 =3.31,P ＜ 0.05).Conclusion The very low birth weight infants treated with mechanical ventilation show steady cerebral blood flow and lower incidence of brain injury after using BUD mixed with pulmonary surfactant.

Objective To investigate the impact of lipoprotein lipase (LPL) gene Hind Ⅲ polymorphisms on plasma lipid and body adipose tissue distribution in simple obese patients. Methods The Hind Ⅲ site of LPL gene intron 8 was detennined by PCR-RFLP in 98 simple obese patients and 51 normal controls. Anthropometry and blood lipid levels were also measured. The parameters for regional adipose tissue distribution were measured by computerized tomography (CT). Results In both groups, H + was the major allele. There was no statistically significant difference in frequencies of genotypes or alleles between the two groups. In obese subjects, Hind Ⅲ H + H + genotype was associated with higher level of triglycerides and lower level of high density lipoprotein-cholesterol ( HDL-C) , as compared with the heterozygote (H + H - ) or homozygote ( H - H - ) genotypes (both P
