The atrio-ventricular valves of the normal heart in 200 Chinese cadavers of different ages were studied. The right atrioventricular valves were classified into three types and the left were classified into two types, according to the number of the main cusps. It was found that percentage of the second type (53.5%) of the right atrio-ventricular valves was higher than that of the first type (43.5%) and the first type (83.0%) of the left atrio-ventricular valves is in the majority, while the second type (17.0%) represents only a small percentage.An accessory cusp is situated between two main cusps. The accessory cusp was found in the right atrio-ventricular valves of 132 cases (66.0%), the majority of which had only one accessory cusp (95 cases. 72.0%), and among them there were 65 cases (37.4%) in which antero-medial accessory cusps were present. The accessory cusps were found in the left atrio-ventricular valves of 103 cases (51.5%), most of them also had only one cusp (92 cases 89.3%) and among them there were 71 cases (62.3) in which postero-medial accessory cusps were present.If the total number of the main and the accessory cusps was considered, in the right ventriculus, four cusps were found in 40.5% of the cases, five in 29.0%, three in 19.5%, six in 9.0%, two in 1.5%, seven in 0.5%; while in the left ventriculus, three cusps were found in 51.5% of the cases, two in 37.0%, four in 11.0% and five in 0.5%.The size of the valves was measured. In the right ventriculus the postero-medial valve is the broadest (40.1 mm), the postero-lateral valve is the highest (24.5 mm). In the left ventriculus the postero-lateral valve is the broadest (36.9 mm), the antero-medial valve is the hightest (20.8 mm). The associated valves are usually larger than the other common main valves, the diameters of which are larger than that of the accessory valves. The perimeter of left artrio-ventricular ring is 79.69 mm and the right is 97.79 mm.

In recent years,with the deepening research on autoinflammatory diseases (AID),more and more diseases have been found and included in the AID category.The clinical manifestations of AID are various,but most of them are not specific.Therefore,it is difficult to distinguish AID from infectious diseases,tumors and other autoimmune diseases,which causes misdiagnosis and delayed diagnosis.This article aims at discussing about the clinical diagnosis and treatment procedure of AID.

Spontaneous abortion is one of the most common gestational conditions, with the morbidity of 1% to 5% in married women. It is a serious problem troubling women at the reproductive age. There are many factors causing spontaneous abortion, among them, spontaneous abortion resulting from endocrine abnormalities can be detected and treated. Prolactin is a major endocrine hormone participating in reproductive regulation and playing an important role in early pregnancy implantation and pregnancy maintenance. When there are unusual levels it is closely related to spontaneous abortion, leading to a necessity to further study the relationship between them. International and domestic research developments in recent years about the correlation between prolactin and spontaneous abortion are discussed in this paper.

According to existing problems in polysaccharide determination methods in new Chinese drug applications, the method suitability, chemical reference selection, components interference and method research were introduced. The author suggests that suitable determination method should be selected according to the structure and property of the polysaccharide, and validated. Some influent factors should be examined to assure the accuracy of the method, such as the stability and using amount of the visualizing reagent, visualizing time, maximum detection wavelength etc. Monosaccharide and other water soluble components should be removed from polysaccharide sample, and suitable reference substance and detection wavelength should be selected. It should pay attention to mutual interference of neutral and acidic saccharide, and use inhibitor to eliminate the interference. Because the slopes of the standard curves are different for different monosaccharide, it is proposed that the types and ratios of the monosaccharide in heteroglycan should be understood, and mixed reference substance solution in the ratio is prepared for determination.

Research of oncogenes related to thyroid cancer has an important significance to reveal pathogenesis and identify benign and malignant lesions.At the mean time,these genes are helpful to find the reliable and feasible detection means of early diagnosis for thyroid cancer.

Objective To investigate the effect of metformin on thyroid hormone and thyrotropin(TSH) in diabetic patients without thyroid hormone replacement.Methods Serum levels of free T3(FT3),free T4(FT4),total T3(TT3),total T4(TT4) and TSH were measured in diabetic patients with or without metformin therapy and the relationship between TSH and metformin was analyzed.Results There were no significant differences in serum FT3(4.65±0.68 vs 4.59±0.67 pmol/L),FT4(17.88±3.26 vs 17.75±2.85pmol/L),TT3(1.79±0.42 vs 1.77±0.38nmol/L),TT4(107.9 ±22.1 vs 109.2±22.1nmol/L) and thyrotropin(ln TSH:0.49±0.83 vs 0.47±0.87 mU/L) between diabetic patients taking and not taking metformin.Conclusions In diabetic patients without thyroid hormone replacement,metformin does not suppress serum TSH

Objective To further study the pathogenesis for congenital heart disease (CHD) and connective tissue growth factor(CTGF) for the early diagnosis of CHD and pulmonary hypertension (PH).Methods Sixty-six cases of children with CHD were selected from the thoracic surgery who were performed in the Children's Hospital of Shanxi Province during the period between Sep.2012 and Jan.2013.Based on the cardiac color Doppler estimation of the pulmonary artery systolic pressure,they were classified into several groups:unincorporated PH group with 16 cases,mild PH group with 18 cases,moderate PH group with 17 cases,and severe PH group with 15 cases.Based on types,the 66 cases could be classified as ventricular septal defect (VSD) group with 23 cases,atrial septal defect (ASD) group with 17 cases,patent ductus arteriosus(PDA) group with 14 cases,and composite(including 2 or more of the congenital cardiovascular anomalies) group with 12 cases.Twenty healthy children who had medical examination over the same period in the Children's Hospital of Shanxi Province were randomly chosen as the healthy control group.The serum concentration of CTGF in the research objects were determined with the aid of double antibody sandwich enzyme-linked immunosorbent assay method.According to the different pulmonary artery systolic pressure and different types of CHD,the serum concentration of CTGF were compared among groups.The correlation of between the CTGF concentration in the serum and pulmonary artery systolic pressure were also analyzed among the groups of children with CHD.Results Quantitative measurement revealed that the serum CTGF concentration measured in the groups of children with CHD were significantly higher than that in the healthy control group(P ＜ 0.05) ; the serum CTGF concentration of the children with CHD and PH was higher than that in the group of children with CHD alone(P ＜ 0.05).With the increase in pulmonary artery pressure,CHD patients serum levels of CTGF also increased(P ＜ 0.05).By the correlation analysis,the results showed that the serum level of CTGF in the CHD groups were positively correlated with the pulmonary artery pressure (r =0.670,P =0.005 ; r =0.514.P =0.029 ; r =0.517,P =0.034 ; r =0.707,P =0.003).The difference in terms of serum CTGF concentration in different types of CHD patients was not significant (F =0.270,P =0.847).Conclusions There exists certain damage in CHD early myocardial fibrosis(unincorporated PH),when combined with PH,myocardial fibrosis increases with the gradual increase of pulmonary artery pressure.However,the degree of myocardial fibrosis shows no correlation with the type of CHD.
