Objective To evaluate the effective of emergent endoscopic injection sclerotherapy ( EIS) for lethal bleeding from esophagogastric varices. Methods In this study, endoscopic injection of 5% sodium morrhuate was used to control esophagogastric variceal bleeding in 176 patients. In all 209 cases, 181 cases suffered from acute lethal bleeding from esophagogastric varices received endoscopic variceal sclerotherapy under the modified Senstaken-Blakemore tube compression. Results The exact bleeding site at the first procedure could be visualized in 166(94. 3% ) patients. The effective rate of EIS was 96. 2% . Multiple procedures were required in the 21 cases of relapsed bleeding. Complications of EIS occurred in 15 cases (8. 5% ) , of which 3(1. 7% ) died. Conclusion Endoscopic injection sclerotherapy under the modified Senstaken-Blakemore tube compression is relatively safe and effective procedure in the treatment of lethal bleeding from esophagogastric varices.

To investigate the distribution of Hepatitis B virus (HBV) genotypes among the population of Dai nationality in Xishuangbanna, Yurman Province HBV genotypes of the Serum samples were tested by PCR-RFLP. This is the first time to discover the B+E genotypes in China. This finding provides new information for understanding the distribution of HBV genotype in China and a provides a basis for establishing a Chinese gene bank.

Objective To investigate the causes, clinical features, treatment and prognosis of gastrointestinal bleeding (GIB) patients in emergency department.Methods To analyze prospectively the clinical data of 168 GIB patients admitted to the emergency department of Peking Union Medical College Hospital during 2006.1-2006.12.Results (1) General data; male: female = 1.75:1 ( 107: 61) , mean age 13-87(56.5 ±17.8) years with a peak in 60-69 years.The percentage of old patients was significantly higher than that of young and middle age ( 52.4% vs 19.6% and 28.0% , P = 0.000 ).( 2 ) The incidence of acute gastric mucosal lesion in patients taking non-steroidal antiinflammatory drugs ( NSAIDs) ( 18.5% ) was significantly higher than that in patients not taking( 0.7% , P = 0.000 ).( 3 ) 86.9% ( 146/168 ) of the patients had anemia.(4) More patients who took emergency gastroscopy could be diagnosed than those patients who did not (89.4% vs 58.5% , P =0.000), while no significant difference could be seen between patients who took emergency enteroscopy and patients who had non-emergency gastroscopy (20.0% vs 57.9% , P =0.315).(5)The hemostatic ratio in GIB patients due to peptic ulcer was obviously higher than that in GIB patients due to other causes (86.0% vs 40.7% ,P =0.000).The rate of emergency operation for GIB patients was 1.8%.Conclusions Most of the GIB patients admitted to tertiary general hospitals are elderly males.NSAIDs administration is one of the most important causes of upper GIB.Upper GIB patients should have gastroscopy as soon as possible, while emergency coloscopy is of little significance in cases with lower gastrointestinal hemorrhage.

Objective To verify the effects of different conc entrations of auecifemine on the function of osteoblast cell expression and oste ogenic ability in vitro . Methods Iliac spongy bone specimens were obtained from twel ve adult patients scheduled surgery. After the bone pieces were treated with col lagenase-trypsin, osteoblasts were obtained from cancellous bones. Then the ost eoblasts were purified and cultivated. They were cultured in medium with various concentrations(1?10 -11 , 1?10 -9 , 1?10 -7 , 1?10 -6 , 1 ?10 -5 , 5?10 -5 mol?L -1 ). The alkaline phosphatase (ALP) acti vity, osterocalcin and osteogenic ability were examined by biochemical assay and radioimmunologic assay (RIA), respectively. Results The co rrelation of auecifemine of different concentrations with ALP activity and osteo calcin secretion was positive. Auecifemine of lower concentrations (1?10 -11 mol?L -1 , 1?10 -9 mol?L -1 and 1?10 -7 mol?L -1 ) s howed the stimulating effect on osteogenic ability and but not higher concentrat ion. Conclusion Estrogen can increase osteoblast ALP activi ty, osteocalcin production, and osteogenic ability.

Objective: To explore the effect of transgenic metallothionein (MT) mushroom on anti-radiation ability of mice. Method: Dried power of transgenic MT mushroom was mixed into the feed of ICR mice. After being fed for 23 d, they were irradiated by 5.0Gy 60Co-?rays. Then their anti-radiation ability was determined after being fed 7 d again. Results: Transgenic MT mushroom can evidently alleviate the injury of platelet and spleen induced by radiation, and apparently increase SOD activity and reduce MDA content in irradiated mice’s serum. Conclusion: Transgenic MT mushroom can improve anti-oxidation ability of irradiated mice.

To investigate the distribution of hepatitis B virus (HBV) genotypes and subgenotypes among the Bai nationality in Dali, a total of 100 serum samples from patients with chronic HBV-infection were collected for the detection of HBV genotypes and subgenotypes by genotype-specific primers and restriction fragment length polymorphism (RLFP), respectively. Among the 100 samples, the proportions of genotype B, C and mixed genotype (B+C) were 41%, 25% and 34%, respectively. All the genotype B strains belonged to subgenotype Ba. In genotype C, 84% were Subgenotype Cs and 12% were subgenotype Ce. The distribution of genotypes B, C and B+C showed no significant difference between male and female patients (P=0.182) and among the age groups of patients (P=0.812). The rates of HBeAg/HBeAg positivity were no significantly different among genotypes B, genotype C and mixed genotype (B+C) (P=0.077/P=0.663). In Dali, genotypes B, B+C and C existed among Bai nationality with chronic HBV-infection, and genotype B was the major genotype. Subgenotypes Ba and Cs were the predominant strains in patients with HBV genotype B/C infection. The most prominent characteristic was the higher prevalent rate of mixed genotype (B+C) in patients.

OBJECTIVETo study the correlation between lumber disc degeneration and sacroiliac joint disorder, in order to provides a new understanding concepts and therapeutic approach for the prevention and treatment of chronic intractable low back pain.

METHODSFrom August 2009 to October 2010,129 cases with lumbar disc herniation were studied with epidemiological methods. Among them, 61 patients with L4, disc herniation included 37 males and 24 females, ranging in aged from 20 to 75 years old, duration of the disease ranged from 1 to 144 months; The other 68 patients with L5S1 disc herniation included 32 males and 36 females,ranging in aged froml8 to 76 years old,duration of the disease ranged from 0.5 to 240 months. The clinical data, symptoms and signs,X-ray characteristics of lumbar spine and pelvis of the patients were investigated by epidemiological. The risk of lumbar disc herniation was calculated with case-control study; independent variables were screened with single factor analysis; the risk factors for lumbar disc herniation were determined with logistic regression analysis, and biomechanics analyses were taken.

RESULTSAmong 129 patients with lumbar disc herniation, 88 cases associated with sacroiliac joint disorders, sacroiliac joint disorder was a risk factor of lumbar disc herniation (OR = 4.61, P = 0.00); 47 cases associated with sacroiliac joint disorders in 61 patients with L4,5 disc herniation, iliac crest uneven caused by iliac rotational displacement was a high risk factor of L4,5 disc herniation (OR = 11.27, P = 0.00); 41 cases associated with sacroiliac joint disorders in 68 patients with L5S1 disc herniation, lumbar sacral angle abnormalities caused by sacral tilt shift was a high risk factor L5S1 disc herniation (OR = 2.31, P = 0.03).

CONCLUSIONLumbar disc herniation and sacroiliac joint disorder are two of fallot, the two factors affect each other and there is a causal relationship. They are common exists in low back pain.

This study is to determine six chlorogenic acids (chlorogenic acid, 5-O-caffeoylquinic acid, 4-O-caffeoylquinic acid, 3,4-di-O-caffeoylquinic acid, 3,5-di-O-caffeoylquinic acid and 4,5-di-O-caffeoylquinic acid) by quantitative analysis of multi-components with a single marker (QAMS). Chlorogeinc acid was used as internal reference to calculate the relative correction factors (RCF) of five compounds. Then the ruggedness of relative correction factors was tested on different instruments and columns. Meanwhile, a total of 4 batches of Lonicerae Flos and 20 batches of Lonicerae Flos extract with five different processing procedures were analyzed by external standard method (ESM) and QAMS, respectively. The ruggedness of relative correction factors was good. And the analytical results calculated by ESM and QAMS showed no difference. The quantitative method established was suitable for the quality evaluation of Lonicerae Flos extract.
