Objective To investigate the efficacy and safety of carvedilol in patients with chronic heart failure (CHF).Methods Forty-six patients with CHF were randomly divided into carvedilol group (n=26) and control group (n=20) on the basis of standard therapy including digitalis, diuretics and ACEI. Before and after treatment, NYHA class, echocardiography and adverse reaction were observed. Results The mean dose of carvedilol was titrated to 25.14?3.05mg/day. After treatment, NYHA class was improved in both groups. Left ventricular end-diastolic diameter (LVEDD) measured by echocardiography reduced [(58.79?8.99)mm vs (64.68?10.12) mm,P

Objective To explore the relationships between erythropoietin( EPO), endothelin - 1 (ET - 1) and perinatal anoxia. Method ELISA was used to test cord blood EPO and ET-1 in 54 high risk neonates as subjects and 14 healthy neonates as controls.Results The cord blood EPO levels in amniotic fluids turbid Ⅲ degree group and group eclampsia/pre - eclampsia were higher than those in control group (t= 4.0842,3 680 allP

Objective To investigate the factors for retinopathy in premature infants. Methods Ophthalmologic mydri was conducted in premature infants and acording to the international classification of ROP, they were diagnosed as ROP. The risk factors of the incidence of ROP were statistically and respectively analyzed. Results Among total of 47 patients, 11 patients were found retinopathy of prematurity. Conclusion The body weight is lower, the gestation is shorter, incidence of ROP is the higher.

A new leaf spot disease on maize mainly caused by Curvularia lunata( Walk )Boed is becoming prevalent in the north of China The conidia play an im portant role during the disease invasion circulation When we cultivated C lunata on sorghum medium, a kind of black and short columned protuberance was obser v ed on the surface of sorghum Further microscopic examination certified that th is special structure was stroma, a kind of conidiomata of C lunata

Nowadays, LAN can't meet the requirements of field communication, and WLAN is playing more and more important role for its strong transmission ability and high mobility. This paper introduces the application of WLAN to filed medicine.

[Summary] Diabetic nephropathy is one of the major chronic microvascular complications of diabetes ,which is the leading cause of end‐stage renal disease ,as well as the main cause of death in diabetic patients. Glomerular endothelial cell is an important component of the glomerular filtration barrier ,which is directly related to the materials of circulation ,and it can be easily damaged by glucose ,lipid and inflammatory factors. Under the hyperglycemia ,the PKC pathway ,the polyol pathway and oxidative stress were activated ,producing an excess of advanced glycation end products and reactive oxygen species ,which damage the endothelial nitric oxide synthase ,reduce the generation of nitric oxide ,while produce a large number of Ang Ⅱ. Ang Ⅱ damage the endothelial cell. In addition ,there are crosstalk between glomerular endothelial cells and endothelial cells ,which also cause endothelial cell injury. Here ,we reviewed the role of endothelial cell injury in the pathogenesis of diabetic nephropathy.

Objective To observe the clinical efficacy and safety of Shenxiong glucose injection and lipo PGE1 injection in treating the lower extremity arteriosclerotic occlusive disease (LEAOD).Methods 80 patients with LEAOD were randomly divided into control group and treatment group. Both groups were given conventional therapy, including reducing blood pressure, blood sugar, blood lipid and anti-infection therapy.Control group was additonally given intra-femoral arterial infusion with urokinase 150000 units plus 15mL 0.9% sodium chloride and 10 mg anisodamine alternately every other day, 5 days for one course, stopping 3 days after another course.Treatment group was treated with intravenous injection Lipo PGE1 injection plus 10 mL 0.9% sodium chloride and intravenous Shenxiong glucose injection per day for 14 days.Clinical efficacy, changes in clinical symptoms, whole blood viscosity, high sensitivity C-reactive protein(hs-CRP), fibrinogen, ankle-brachial index(ABI), the inner diameter of the dorsalis pedis and the peak systolic velocity( PSV) of dorsalis pedis were compared and analyzed pre and post-treatment.Adverse drug reactions were recorded during the treatment.ResuIts The efficiency for the patients in the treatment group (90.0%) was higher than that in control groups(72.5%) (P<0.05).The symptoms of numbness and cold limbs, whole blood viscosity, ABI, hs-CRP improved more significantly in the treatment group (P<0.05).No adverse event occurred in the treatment group and 2 patients in control group had mild dry mouth.ConcIusion Shenxiong glucose injection combined with lipo PGE1 injection for the treatment of LEAOD is effective and safe and should be introduced in clinical practice.

Objective To evaluate how to select operation procedures for different CT manifestation of splenic artery aneurysm ( SAA) with posthepatitic cirrhosis. Methods In 61 cases with SAA,the CT manifestation ( location,number,size,portal vein,varicose vein,proxi-mal splenorenal shunt and spleen changes) of SAA,clinical features of cases,and operation approach were were retrospectively analyzed. Re-sults 4 patients who have the primary tumors located in the distal splenic artery with diameter 1. 0~2. 0 cm,spleen kidney shunt and mega-losplenia were given aortic aneurysm exclusion and branch aneurysms embolism by stages. Amiong the 15 cases of tumors resection,splenecto-my and devascularization,there were 4 cases of the primary tumors located in the middle of splenic artery and 11 cases in the distal splenic artery. There were 15 cases whose diameter of the primary tumor were lager than 2. 0 cm and 13 cases whose diameter of the primary tumor were 1. 0~2. 0 cm. There were 4 cases of cavernous transformation of portal vein,5 cases of splenic and gastric varices,15 cases of esophage-al and gastric varices,4 cases of splenic and gastric venous shunt,15 cases of megalosplenia and 4 cases of splenic infarction. Tumors resec-tion and branch aneurysms embolism by stages were conducted in 7 cases. The primary tumors located in the proximal splenic artery occured in 7cases,and the diameter of the primary tumor were 1. 0~2. 0 cm occured in 7 cases. Esophageal and gastric varices occured in 2 cases and splenomegaly occured in 7 cases. And there were 4 cases whose diameter of the tumor were 1. 0~2. 0 cm were given tumor resection and re-construction of splenic artery and continuity, including 1 case of proximal splenic artery,2 cases of medial splenic artery and 1 case of distal splenic artery. Conclusion Operation procedures were confirmed by CT findings such as location,number,size,portal vein,varicose vein, proximal splenorenal shunt and spleen changes of SAA combined with age,gender,body mass index and history.
