Objective To observe the influence of ademetionine for the proteometabolism and fibrosis indexes of patients with chronic hepatitis B.Methods110 patients with chronic hepatitis B in our hospital from January to December 2016 were randomly divided into control group(conventional treatment of hepatitis B group)55 cases and observation group(conventional treatment and ademetionine group)55 cases.The serum expression levels of proteometabolism and fibrosis indexes of two groups before the treatment and after the treatment were detected and compared.ResultsThe serum expression levels of proteometabolism and fibrosis indexes of two groups before the treatment were compared,there were no significant differences,while the serum expression levels of proteometabolism indexes of observation group after the treatment were all higher than those of control group,the serum expression levels of fibrosis indexes were all lower than those of control group,there were all significant differences(all P<0.05).ConclusionThe ademetionine can significantly improve the expression state of proteometabolism and fibrosis indexes of patients with chronic hepatitis B,so the application value for the patients with chronic hepatitis B is relatively higher.

The purpose of this paper was to evaluate the relationship between the thrombosis and secretory duct dilation, lesion size, clinical types, nature (primary or recurrent) and duration of illness in the development of ranula. A total of 229 cases of sublingual gland cysts were treated with surgical resection from Jan. 1990 to Feb. 2010. The patients' data were investigated on histopathological findings, size of ranula, the clinical types, nature of ranula (primary or recurrent) and duration of illness. Sections from the paraffin-embeded blocks were HE-stained. CK expression was immunohistochemically detected. Among 229 cases the incidence of venous thrombosis was 58.52%. The incidence of venous thrombosis with or without duct dilation was 73.25% and 26.39% respectively, with a significant difference between the two groups (P<0.005). The incidence of venous thrombosis of ranulas with diameter larger or less than 3 cm was 72.22% and 46.28% (P<0.005). The incidence of venous thrombosis of oral ranula, plunging ranula and mixed ranula was 49.37%, 77.19% and 85.71% respectively, with a significant difference found between oral and plunging or mixed ranula (P<0.01). The incidence of venous thrombosis in ranula patients with duration of illness longer or less than 3 months was 69.77% and 51.75% (P<0.01). The incidence of venous thrombosis with recurrent and primary ranulas was 51.85% and 64.85%, without a significant difference noted between them (P>0.05). It is concluded that the formation of venous thrombosis was related to the dilation of secretory duct, lesion size, clinical types, duration of lesion but formation of venous thrombosis was not related to the nature (primary or recurrent) of ranulas.

Objective To elucidate the relationship between quality of life (QOL) and disease activity of systemic lupus erythematosus (SLE),as well as to reveal the factors impacting disease activity and the QOL of SLE utilizing the combination of SLE-specific quality of life questionnaire (SLEQOL) and the medical outcomes survey short form 36 (SF-36).Methods SLEQOL and SF-36 health survey questionnaire were applied.Information on gender,disease duration,age,education level were collected.Serum complement (C3 and C4) level and erythrocyte sedimentation rate (ESR) were measured.Patients were divided into inactive,mild active,moderate active and severe active respectively according to SLE disease activity index (SLEDAI).Pearson's product moment correlation coefficient was used to analyze the correlation between the activity of disease and the QOL.Multiple linear regression was employed to explore the factors which could impact on SLEQOL.Results The physical function of SLEQOL was positively correlated with SLEDAI (r=0.36; P＜0.05).The association between reported health transition of SF-36 and SLEDAI was positive (r=0.19; P＜0.05).Physical functioning,role-physical,role-emotional,body pain and vitality were all negatively correlated with SLEDAI (r:-0.20,-0.19,-0.19,-0.19,-0.21 respectively; P＜0.05).The scores of patients with severe disease activity were significantly increased in the physical functioning of SLEQOL than other three groups (18±10 vs 11±5,12±6,13±7; P＜0.05).Scores on the Health transition of patients with moderate and severe disease activity were lower than those of whom with mild disease activity (23±28.14±17 vs 34±39,P＜0.05).Patients with mild or severe disease activity had lower score than those of patieuts in disease inactive (30±41,34±39 vs 44±44,P＜0.05).Multiple linear regression analyses showed that disease duration and education level might be the influencing factors of SLEQOL.Conclusion QOL of patients with SLE is related to the level of disease activity and is impacted by disease duration and education.

Objective: To analyze the distribution and drug resistance characteristics of clinical separation germ in a hospital from 2013 to 2015 to provide reference and basis for the prevention and control of nosocomial infection and rational use of antibiotics.Methods: The microbial susceptibility of isolated strains was detected using the conventional methods, and the drug sensitivity was analyzed by BioMerieux ATB 1.22.The drug sensitivity was determined according to CLSI 2014 criteria.Results: A total of 18 421 specimens were isolated during 2013 and 2015, and a total of 3 744 strains were isolated with the total positive rate of 20.32%.The separation and identification of pathogenic bacteria at the top 5 were Escherichia coli (967 strains, 44.34%), Bauman Acinetobacter (323 strains, 14.81%), Klebsiella pneumoniae (312 strains, 14.31%), Staphylococcus aureus (297 strains 13.62%) and Pseudomonas aeruginosa (282 strains, 12.92%).Besides the natural resistance of Klebsiella pneumoniae to amoxicillin, the resistance rate of Escherichia coli to piperacillin was over 75%, while the sensitivity rate of Klebsiella pneumoniae to piperacillin and tazobactam was more than 90%.The sensitivity of Acinetobacter baumannii and Pseudomonas aeruginosa to clinical antibiotics was basically below 40%, and the overall resistance level was higher than that of Bauman.MRSA was sensitive to nitrofurantoin, minocycline, quinupristin-Dafoe and leptin glycopeptide antibiotics (such as teicoplanin and vancomycin).Conclusion: The hospital should strengthen the monitoring of bacterial resistance and track the results in a timely manner so as to provide reference for the rational drug use in clinical practice.

BACKGROUND: Epidural block(EB) is one of the effective and widely used remedies for lumbar disc herniation(LDH) . Animal experiments have been conducted to study the changes in the local tissue structure in the spinal canel after several treatments with EB.OBJECTIVE: To study the effect of EB for LDH on the local tissue structures in the spinal canel.DESIGN: A non-randomized and controlled clinical observation.PARTICIPANTS: Department of Pathology and Laboratory of Electron Microscope of an Affiliated Hospital of a University.SUBJECTS: Forty patients with LDP, who failed to respond to EB treatment and subsequently received discectomy in the Department of Orthopaedics,First Affiliated Hospital of Sun Yat-sen University from May 1992 to December 1997, were enrolled in this study, with 20 patients receiving discectomy but not EB treatment serving as the control group.METHODS: From the 60 cases, totally 120 specimens of yellow ligament and the disc tissues were obtained during discectomy for optical microscopical examination. A portion of the yellow ligament and the lumbar disc tissues were chosen from EB group(12 cases) and non-EB group(10 cases), respectively, for electron microscope examination(involving altogether 44specimens) . The changes in histology and ultrastructnres in the specimens were compared between the two groups.MAIN OUTCOME MEASURES: ① Main results: the reactive proliferation of the tunica adventitia and inflammatory reaction of the intervertebral disc and yellow ligament; ② Secondary results: changes in the ultrastructure of the anulus fibrosus, nucleus pulposus and yellow ligament.RESULTS: No significant difference was found between the two groups either in light microscopy or electron microscopy in the degree of smoothness and the inflammatory reaction of the cavosurface of the yellow ligament and the disc tissues, nor in the cellular ultrastructures and fibrous arrangement.CONCLUSION: There is no direct relationship between lumbar EB and epidural scar adhesion formation. EB does not affect the ultrastructures of the local tissues in the spinal canal, but care must be taken of the sterilization in the surgical procedure, as chronic inflammatory reaction in the yellow ligament and disc tissues can be present in some patients.

ObjectiveTo study the effect of astragaloside Ⅳ(AS-Ⅳ) on glucose-induced podocyte adhesion and its possible mechanism. MethodsConditionally immortalized mouse podoeytes were treated with 10, 50, 100 mg/L AS-Ⅳ and with 100 mg/L AS-Ⅳ for 3, 6, 12, 24 h. Cell attachment was measured by fluorescence and centrifugation cell adhesion assays, respectively. Expression of α3β1 integrin mRNA and protein was examined by real-time PCR and Western blot. ResultsHigh glucose induced a significant reduction in adherent podocytes compared to normal glucose group (P<0.05). AS-Ⅳ improved high glucose-induced podocyte adhesion in a time- and dose-dependent manner. Real-time PCR and Western blot analysis revealed that high glucose-induced down-regulation of α3β1 integrin in podocytes were significantly meliorated by AS-Ⅳ (P<0.05). ConclusionAstragaloside Ⅳ improved high glucose-induced podocyte adhesion which may be mediated through α3β1 integrin up-regulation.
