Lymphorrhea and lymphocele are the common complications after urological pelvic lymph node dissection, which are difficult to diagnose and treat. Up to now, a few studies of lymphorrhea and lymphocele were reported, and there is no relevant diagnosis and treatment guideline. The pathogenesis, treatment and prevention of lymphorrhea and lymphocele formation after urological pelvic lymphadenectomy were reviewed in this article.The mechanism of occurrence includes leakage and exudation of lymph-vessels. The high risk factors are old age, open surgery and perioperative use of anticoagulants. Most patients can be cured by nutrition management and percutaneous catheter sclerotherapy. Closing lymph-vessels and stumps may paly an important role in prevetion of lymphorrhea and lymphocele.

This study was aimed to observe the effect of Softening Liver and Reducing Enzyme Mixed Agent (SLREXA) in the prevention of acute liver injury rats induced by carbon tetrachloride (CCl4). A total of 60 male SD rats were randomly divided into 6 groups, which were the SLREXA low-, middle-, high-dose group, glucurolactone group, normal group and model group. Intraperitoneal injection of CCl4 was used to induce acute liver injury rat mod-el. Intragastric administration of SLREXA was given to each Chinese medicine group. Intragastric administration of distilled water was given to the normal group and the model group. Intragastric administration of glucurolactone aque-ous solution was given to the glucurolactone group. On the 12th day of the experiment, after 16-hour fasting, rats were killed. Pathological changes in liver tissues were examined. Blood serum was determined for alanine aminotrans-ferase (ALT) and aspartate aminotransferase (AST). The liver homogenate was determined for superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), glutathione (GSH), catalase (CAT) and malondialdehyde (MDA) in liver tis-sues of rats. RT-PCR was used to detect the expression level of mRNA in liver heme oxygenase-1 (HO-1). The re-sults showed that in the microscopic examination of liver tissues, compared with the model group, different doses of SLREXA can alleviate pathological damages of liver in varying degrees. Levels of blood serum ALT and AST content in different doses of SLREXA groups and glucurolactone group were significantly lower than those of the model group (P < 0.05 or P < 0.01). Compared with the model group, contents of GSH-Px, GSH, SOD, CAT in the liver ho-mogenate were significantly increased, and MDA content was decreased significantly (P< 0.05 or P< 0.01) in differ-ent doses of SLREXA groups and glucurolactone group; compared with the model group, the HO-1 mRNA relative expression quantity in the normal group and each treatment group increased obviously, with statistical significance (P< 0.05 or P< 0.01). It was concluded that SLREXA can prevent CCl4-induced liver injury rats with definite thera-peutic effect.

Scientific research archives management work is a basic work in the hospital work,establish hospital scientific research management information system,implementation of scientific research archives management informationization can not only realize the scientific research resources sharing,and can greatly improve the scientific quality of service and efficiency.This paper analyzes the necessity of scientific research archives information management,and the main plate and the function of information management system of scientific research archives has carried on the detailed introduction.

Objective To discuss the effect of small needle knife therapy on collagensⅠ and Ⅲ in the hypertrophic scar tissues that was subcutaneously transplanted into nude mice. Methods Six samples of human hypertrophic scar tissues without cuticle were subcutaneously transplanted into the back of 24 nude mice to create the animal models of hypertrophic scar. Ten days after of the operation,the mice were divided into control,0.1 mg/ml triamcinolone,0.2 mg/ml triamcinolone,and small needle-knife groups with 6 mice in each. Specimens of the scar tissues were collected in 14 days for immunohistochemistry to detect the collagen Ⅰ and Ⅲ. Results In all the groups,collagens Ⅰand Ⅲ distributed extensively in the cytoplasm of fibroblast and tissues. Image analysis showed that the concentration of collagens Ⅰand Ⅲ in 0.1 mg/ml and 0.2 mg/ml triamcinolone groups were significantly lower than those in the control (0.09?0.03,0.11?0.05 and 0.12?0.02,0.11?0.01 vs. 0.17?0.04,0.19?0.03,P0.05). Conclusions Small needle-knife therapy can reduce the concentration of collagens Ⅰand Ⅲ in transplanted hypertrophic scar tissues in nude mice.

Early use of statins after onset of acute ischemic stroke can improve the functional prognosis of patients and reduce in-hospital mortality.This article reviews the preclinical and clinical trials of statins for the treatment of ischemic stroke.

Objective:To study the best opportunity for minimal invasive puncture in the treatment of hypertensive intracerebral hemorrhage.Methods:Forty-one patients with hypertensive intracerebral hemorrhage were randomly divided into four groups:<6 h,6-12 h,12-18 h and 18-24 h from the onset of symptoms.The comparison among groups in outcome measures were performed,including the rebleeding rate,short-term efficacy,long-term efficacy,mortality,and excellent and good rate.Results:The incidence of complication such as rebleeding etc had no significantly difference in the four groups.The excellent and good rates of clinical outcomes at 3 months were the<6 h group>6-12 h group,and 12-18 h group>18-24 h group(P<0.05).The 18-24 h group had the highest mortality(30%,3/10).Conclusions:Within 6 h after the onset of hypertensive intracerebral hemorrhage was the best opportunity for the minimal invasive puncture.

Objective To investigate the operative methods and their efficacy of the modified decompressive craniectomy in combination with indirect revascularization for the treatment of massive cerebral infarction. Methods The clinical data of 15 patients with massive cerebral infarction who underwent modified decompressive craniectomy in combination with encephaloduroarteriomyosynangiosis were analyzed retrospectively. The clinical efficacy was assessed according to the mortality, Barthel Index and modified Rankin scale. Results All the patients were followed up, and 12 patients survived 3 months after operation, of those, 4 had a good functional outcome; 11 patients survived 6 month after operation, of those, 7 had a good functional outcome. Conclusions The modified decompressive craniectomy in combination with indirect revascularization for the treatment of massive cerebral infarction could effectively treat massive cerebral infarction and increase the survival rate and life quality of patients, however, the surgical timing, surgical indications and surgical skills are needed to master accurately.

ObjectiveTo discuss the incidence,treatment and effect of cryptogenic hemoptysis (CH).MethodsPatients with CH were selected from 231 patients with hemoptysis according to clinical evaluation,chest radiography,fiberoptic bronchoscopy and CT scan,and the clinical data and treatment methods were retrospectively analyzed.ResultsFifty-three of 231 patients referred for CH,the incidence of CH was 22.94 ％ (53/231),of which 45 (45/53,84.91％ ) received internal conservative treatment and 8 (8/53,15.09％) received bronchial artery embolization (BAE).High resolution CT (HRCT) showed ground-glass opacities in 20 CH patients after hemoptysis.Bronchial arteriography showed abnormalities,including arterial enlargement and localized hypervascularity in 8 patients and systemic to pulmonary shunting in 3 patients.No recurrence of hemoptysis was observed during 1 to 8-year follow-up.ConclusionBleeding can be controlled in most of CH patients by internal conservative treatment,only a few patients with massive hemoptysis need BAE,and both treatments have good short and long term results.

Objective To analyze the genotypic characteristics of hepatitis B virus (HBV)C/D recombinant of two types of newly discovered HBV genotypea found in Western China.Methods The whole genomes of 17 HBV strains isolated from Western China were amplified by polymerase chain reaction (PCR). Bioinformatic softwares were used for the analysis of full genome structure,genetic distances and recombination points.Results The heterogenicity of the HBV C/D recombinant was more than 8% compared with genotype A,B,D,E or F,but 3.8% 0A-8.O% compared with genotype C Based on phylogenetie analysis, a11 C/D recombinant strains clustered within genotype C.but were rouped into two other clusters within the genotype C independently from C1-C5 subgenotypes,which were two kinds of new HBV/C genotypea.Condusion The HBV C/D recombinant could he considered as tWO kinds of new subgenotypea of HBV genotype C which are different from subgenotype C1-C5 based on the genetic distances analysis.
