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.

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.

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.

Pancreatic cancer is one of the worst digestive malignancies characterized by non-specific symptoms, rapid progression and high mortality. Despite great efforts that have been made in basic and clinical research, the prognosis remains poor with an overall 5-year survival rate of less than 5%. Complete surgical resection is the only curative treatment option, but the curative resectabillty is still about 15% in China. Pancreatic surgery is considered one of the most techni-cally demanding and challenging procedures. The development of pancreatic surgery in China depends not only on the progress in surgical techniques, but also the specialization on pancreatic surgery. There has been advancement in combined therapy with a modern interdisciplinary approach including chemotherapy,radiotherapy, biotherapy and thermotherapy. The research pro-gress of gene therapy on pancreatic cancer showed us some hopes for the future. The outcome of pancreatic cancer treated by Chinese medicine with herbal drugs is encouraging, but still needs the support of more solid evidences from randomized con-trolled trials. It is suggested that the combined therapy should play an important role in the treatment of pancreatic cancer, and the fallow-up should be paid more attention.

Objective To evaluate the clinical value of Nevin and AJCC staging system for gallbladder carcinoma. Methods In this study 90 patients diagnosed as gallbladder carcinoma underwent operation in Renji Hospital from February 2000 to October 2006. Patients were staged according to Nevin and AJCC staging system. The difference of survival rate, tumor resection rate, ratio of tumor-free resection margin and surgical procedures were analyzed. Results The survival rate, tumor resection rate and ratio of tumor-free resection margin decreased progressively with increasing Nevin and AJCC stage (P < 0. 05). There was no significant difference between the survival rate for Nevin Ⅲ or Ⅳ patients undergoing radical resection and simple cholecystectomy (P > 0. 05). In Nevin Ⅴ patients, the survival rate for radical and extensive radical resection patients was higher than for palliative patients (P < 0. 05). In AJCC Ⅲ patients, the survival rate for radical patients was significant higher than for palliative patients (P < 0. 05). Nosignificant difference was found between radical and palliative patients in survival time in AJCC Ⅳ (P > 0. 05). 52 patients in AJCC Ⅲ and Ⅳ were staged to Nevin Ⅴ according to Nevin staging system. The survival rate and resectable rate for the patients in AJCC Ⅲ were higher than in AJCC Ⅳ (P = 0. 0001, 0. 001 respectively). The rate of radical operation in AJCC Ⅲ was higher (P = 0. 001), and the rate of palliative operation in AJCC Ⅳ was higher (P = 0. 001). Conclusion Both Nevin and AJCC staging system are useful in the judgement of survival, reeectability, ratio of tumor-free resection margin and the optimal operation. AJCC staging system is more applicable for gallbladder carcinoma patients at advanced stage in terms of predicting prognosis.

BACKGROUND: Migraine is usually located in the course of Shaoyang channel, and the curative effect of treatment with methods of treating Shaoyang disease by dispersing and dispelling wind (DW) as well as relieving pain (RP) on migraine is prominent, but how about the effects of these two ways on thrombogenesis in vitro and the function of platelet aggregation (PA)?OBJECTIVE: To probe into the effect of treatment of Shaoyang disease and methods of DW and RP on thrombogenesis in vitro and function of PA throughthe experiments of thrombogenesis in vitro and function of PA in rats, and investigate the compatible significance of DS and DW as well as RP through formula compatible experiment.DESIGN: Completely randomized grouping design and controlled trial.SETTING: Department of Prescription, College of Basic Medical Sciences,Heilongjiang University of Chinese Medicine.MATERIALS: The experiment was conducted in the Laboratory of Department of Prescription, Heilongjiang University of Traditional Chinese Medicine from March to August 2000. Sixty healthy adult Wistar rats were randomly divided into 6 groups: Normal control group, Shaoyang treatment group (group Ⅰ ), DW and RP group (group Ⅱ ), high-dose and whole-prescription group (group Ⅲ), low-dose and whole-prescription group (group Ⅳ), and positive control group with 10 rats in each group.METHODS:① Positive control group:Gastric perfusion of 0.034 g/mL compound divaside slice suspension (made by Harbin Second Biochemical Pharmacy co., Ltd) was given to rats (0.39/kg); Group Ⅲ and Ⅳ (ingredients: Chaihu 20 g, huangqin 10 g, banxia 15 g, gancao 10 g, chuanqiong 20 g, tianma 15 g, xixin 5 g, quanxie 5 g, wugong 5 g): Gastric perfusion of 1.5, 0.75 g/mL of complete prescription was given to rats (17.40, 8.70 g/kg);Group Ⅰ (ingredients: Chaihu 20 g, huangqin 10 g, banxia 15 g, gancao 10 g) and group Ⅱ (ingredients: Chuanqiong 20 g, tianma 15 g, xixin 5 g, quanxie 5 g, wugong 5 g): Gastric perfusion of 0.75 g/mL agents of treatment with DS and DW wind antidyne was given to rats as 8.70 g/kg; Normal control group: Gastric perfusion of normal saline of the same volume wasgiven to rats.Intervention on rats of all groups lasted 12 days.② Experiment of thrombogenesis in vitro: The cephalic artery of one side was seperated 2 hours after the last time of administration. The distal part was deligated, the blood current in proximal part was blocked with bulldog clamp and the arterial cannula was inserted into the cephalic artery. Loosened the bulldog clamp, blood of 1.8 mL was collected and put into the rotary ring of thrombogensis meter to rotate for 15 minutes at 17 r/min,and then poured the thrombus, measured the length and humid weight of thromb. After that,dried the humid thromb and measured the dry weight.③ Determination of PA:The packing fraction (PF) in the 1st and 5th minutes as well as the maximal packing fraction (MPF) and assembling inhibition ratio of platelet-rich plasma within 5 minutes were recorded with test.MAIN OUTCOME MEASURES: Effect of treating Shaoyang disease nephelometry.④ Differences of measurement data were compared with tand methods of DW as well as RP on thrombogenesis in vitro and the function of PA.RESULTS: A total of 60 rats were involved in the analysis of results. ①The length, humid weight and dry weight of thrombogenesis in vitro in group Ⅲ and Ⅳ, positive control group and group Ⅱ were obviously lower than those in group Ⅰ (P ＜ 0.05). ② The PF in 1st, 5th minute and the maximal aggregathe normal control group (P ＜ 0.05-0.01); The humid weight and dry weight of thromb in group Ⅳ were significantly lower than those in tion (MA) of blood platelet in rats of each group were significantly lower than those in the normal control group (P ＜ 0.05-0.01), and the curative effect on rats in the positive control group, group Ⅲ and Ⅳ as well as group Ⅱ were better than that in group Ⅰ.CONCLUSION: There are no significant effects of dispersing thrombogenesis in vitro and inhibiting PA by only treating Shaoyang disease. The effect of combined prescription of DW and RP as well as treatment of Shaoyang disease are obviously enhanced.

OBJECTIVE In order to explore and control the risk factors of nosocomial infection in intracerebral hemorrhage.METHODS To study prospectively in 837 hospitalized patients with intracerebral hemorrhage in our hospital from Jan.1997 to June 1999. RESULTS It was showed 215 cases of the nosocomial infection were found among 837 cases with the intracerebral hemorrhage(25.8%).Among them,nosocomial lower respiratory tract infection was the highest(39.1%),the second one was the urinary tract(27.8%).Nosocomial infection was closely related with such factors as the aging,location and volume of intracerebral hematoma,disturbance of consciousness, smoking,blood sugar,invasive operation,antibiotic prophylaxis,bed-days.Whereas serum cholesterol was a protective factor.CONCLUSIONS Nosocomial infection was still a high frequent complication in intracerebral hemorrhage and it should be paid attention.This is the most important step to control nosocomial infection of intracerebral hemorrhage in the hospital.

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

Phase Ⅱ metabolic enzymes play pivotal role in the biotransform and metabolism of exogenous substances, which might influence its ability of metabolism and detoxification to exogenous carcinogens.Polymorphism have been demonstrated in various phase Ⅱ metabolic enzymes and etiology studies showed that individuals exposed to the same environment could develop different susceptibility to tumorigenesis due to different metabolic enzyme polymorphism. Here, we summarized the effects of phase Ⅱ metabolic enzyme polymorphism on the risk of cancer.
