?AIM: To evaluate the clinical effects, corneal surface shape and corneal thickness variation after treated by Danzhi Xiaoyao Capsule combined with hypromellose 2910, dextran 70 and glycerol eye drops for dry eye in menopausal patients.?METHODS: Eighty menopausal patients ( 160 eyes ) diagnosed as dry eye were randomly divided into groups A and B ( 40 patients each ) . Group A was treated with hypromellose 2910,dextran 70 and glycerol eye drops only and group B was treated with Danzhi Xiaoyao Capsule and eye drops. Before and 1mo after treatment, the clinical effects were evaluated by symptom scores, fluorescein staining ( FL ) , tear film breakup time ( BUT ) and Schirmer Ⅰ test. While the corneal surface regularity index (SRI), surface asymmetry index (SAI) and central corneal thickness ( CCT) were observed.? RESULTS: At 1mo after treatment, the symptoms scores and FL scores of the 2 groups decreased significantly( P<0. 05 ); BUT and SⅠt were significantly increased (P<0. 05). SRI and SAI gradually increased with dry eye exacerbations, after treatment the two parameters significantly reduced than those before treatment. SRI of group B improved significantly more than group A. CCT gradually got thinning with the dry eye condition worsened, which also significantly increased after treatment (P<0. 05);but there was no difference between 2 groups before and after treatment(P>0. 05).?CONCLUSION: Combination therapy of Danzhi Xiaoyao Capsule and hypromellose 2910, dextran 70 and glycerol eye drops for menopausal patients with dry eye is more effective than single eye drops, and can improve the symptoms and signs.

[Objective] To investigate the relationship of different types of gestational diabetes mellitus (GDM) and thyroid function.[Methods] A Total of 3846 cases,which received prenatal examination,delivered in the Eastern Hospital of the First Affiliated Hospital,Sun Yat-sen University and performed a 75 g oral glucose tolerance test (75 g 0GTT) at 24-28 gestational weeks,from Jan 1st,2014 to Dec 31st,2015,were divided into 2 groups.Normal blood glucose group:the result of OGTT (fasting plasma glucose,1 hour glucose and 2 hour glucose) was normal;Gestational diabetes mellitus group (GDM group):the result of 0GTT was abnormal.GDM group were divided into Ⅰ,Ⅱ,and lⅢ.GDM Ⅰ defined as one abnormal blood glucose of result.GDM Ⅱ:two abnormal blood glucose.GDM Ⅲ:three abnormal blood glucose.1868 cases of healthy pregnant women were reselected as the control group.TSH,FT4 and TPO Ab were detected in two groups.Analysis of Variance,Mann-Whitney U test,Kruskal Wallis rank test or Fisher's test was used for statistical analysis.[Result] There were statistically significant difference in TSH,FT4 between GDM subgroup and control group (P =0.012,P =0.002).TSH median trend to increase in GDM Ⅱ,and FT4 median trend to decrease in GDM Ⅱ.The Prevalence of hypothyroidism in GDM Ⅱ and GDM Ⅲ were higher than those in control group.[Conclusion] The GDM group with two or three abnormal blood glucose had a higher incidence thyroid gland dysfunction,especial with subclinical hypothyroidism.We should fully test the thyroid function,treat diabetes as early as possible and improve the pregnancy outcome as we could.

Objective The purpose of this study was to evaluate the safety and clinical oulcomes of aortic valve replacement (AVR) performed with minimally invasive technique.Methods From June 2010 to October 2011,20 cases of minimally invasive AVR were performed.The mean age was (47.60±12.28) ;12 males and 8 females.All patients are ventilated with a double-lumen endotracheal tube,through the 3nd anterior intercostals space with a 5 -6cmskin incision,right femoral artery and vein cannulation are used to establish CPB,direct aortic cross-clamped by Chitwood sliding clamp through the right 4th intercostals space,and completed the aortic valve replacement.Results Mean length of incision was (4.73±0.54)cm.Mean duration of cardiopulmonary bypass was (124±39.83)min,crossclamp time was (97.21±33.17) min.Median intubation time was (13.55±3.87)hours.Median duration of intensive care and postoperative hospital stay was (16.34±3.82)hours and (6.63±1.45) days,respectively.Hospital mortality was 0.There was no perivalvular leakage,Conclusion Minimally invasive aortic replacement with a modified Port-Access approach is feasible,small incisions,more cosmetic,shorter length of bospital stay and less need for blood transfusion are attainable.

Objective To confirm the clinical diagnosis of complete androgen insensitivity syndrome (CAIS) by molecular genetic testing in a large family. Methods PCR was performed to amplify the coding region of androgen gene, followed by direct sequencing in the patients with CAIS and relatives in this family. Results A missense mutation Arg773His was identified in the patients (homozygous) and carriers(heterozygous). Conclusions Mutation Arg773His in the AR gene leads to CAIS in this family. Molecular genetic testing of CAIS facilitates not only prenatal genetic diagnosis but also preimplantation genetic diagnosis and offers genetic counseling for future pregnancies to abandon the transmission of the mutated X chromosome to the coming generation.

With comparison of three different methods for the marking of amines compound, an optimal deri vatization method was selected.5-(2-Hydroxyethyl) benzoacridine (HBA) reacts with coupling agent N,N'-carbonyldiimidazole(CDI) to form an activated amide intermediate 2-(benzoacridin) ethyl-imidazole-1-carbox-ylate(BAEIC).BAEIC, which is dual-sensitive probe, reacts preferably with amino compounds at 80 ℃ in the presence of 4-dimethylaminopyridine(DMAP) catalyst in N,N-dimethylformamide(DMF) solvent to give the corresponding sensitively fluorescent derivatives with an excitation maximum at λ_(ex) of 280 nm and an emis sion maximum at λ_(em) of 510 nm.BAEIC-amine derivatives simultaneously exhibited high ionization potential with percent ionization (changing from 5.62% to 58.08% in aqueous acetonitrile and from 2.14% to 56.58% in aqueous methanol.Derivatives were not only sensitive to fluorescence but also to MS ionizable potential.The fluorescence detection limits(5/iV = 3) were 0.12-0.59 μg/L.The online APCI-MS detection limits were 1.9-14 μg/L(S/N=5).

Plasma ghrelin level was measured by RIA in 49 grids with idiopathic central precocious puberty(ICPP)and 35 girls with simple premature thelarche(PT).The results showed that the plasma ghrelin level was negatively correlated with Tanner stage,bone age,Lid at 15,30 and 60 min after GnRH activation, uterus and ovary volumes.The plasma ghrelin level in the ICPP group was remarkably lower than that in the PT and control groups(both P

Objective：To explore the effect of group psychological service on mental health of the children left behind in rural areas.Methods：Totally 222 children left behind in rural areas were selected randomly and divided into intervention group and control group.The intervention group accepted 8 times of group psychological service.The Eysenck Personality Questionnaire(EPQ),Center for Epidemiological Studies of Depression scale for Children(CES-DC),Rutter Children's Behavior questionnaire for completion by teacher,Piers-Harris Children `s Self-concept Scale(PHCSS)were used in both groups to evaluate the effect at baseline,the end of the 7th intervention,and 6 months after the end of the intervention.Results：After intervention,the intervention group got lower scores than control group in EPQ-N [(8.2±5.8)vs.(10.2±6.1),P<0.05]in the first retest,and in CES-DC [(15.9±7.3)vs.(18.8±7.7),P<0.05]in the second retest.The group gained higher scores in anxietyand happy and satisfaction factors of PHCSS [(6.6±3.4)vs.(5.6±2.7),(6.5±1.9)vs.(5.7±1.8);Ps<0.05]. Conclusion：Group psychological service are effective to children left behind in rural areas with depression emotion and had a role in children's personality remodeling.
