Objective To study the anti-hepatofibrotic effects of rhubarb and tetrandrine in experimental rat model, and to explore its possible mechanism. Methods The experimental hepatic fibrosis was induced by subcutaneous injection of CCl 4. The rhubarb and tetrandrine were administered through gastric tube respectively. The liver function test was performed by enzyme kinetics and the extracellular matrix (ECM) contents were determined by radioimmunoassay. The pathological changes of liver tissues were detected by HE and VG staining; meanwhile, ultra microstructural changes were observed by electron microscope in randomly selected samples. Results Both rhubarb and tetrandrine could improve the liver function in liver fibrosis, decrease the contents of ECM and reduce the degree of liver fibrosis, with the best results in rats receiving high dosage of rhubarb and low dosage of tetrandrine. Conclusions Rhubarb and tetrandrine could protect hepatocytes, inhibit the ECM synthesis, and thereby could prevent the development of liver fibrosis and cirrhosis in the experimental animal models.

As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy.

Objective To explore the effect of prevention of hemorrhagic cystitis (HC) after hematopoietic stem cell transplantation (HSCT) with hyperhydration, forced diuresis and alkalinizing plus infusion mesna. Methods 32 cases of patients receiving HSCT were included in this study. 2 cases of severe aplastic anemia (SAA) received total body irradiation (TBI)+cyclophosphamide(CTX)(TBI-CTX) regimen,and the remaining 30 patients were using the classic busulfan+CTX (BU+CTX) regimen. All patients were treated with mesna combined with hydration, forced diuresis and alkalization to prevent HC. Ganciclovir and acyclovir were used to prevent cytomegalovirus (CMV) and other viral infections and monitor CMV-IgM levels of the blood. Encourage patients to urinate every hour, testing urine pH value and the calculation of urine output, every 6 h review and testing of urine routine,central venous pressure (CVP), each of 8 h of serum electrolytes. Results Only 1 patient at 6 months after transplantation appeared delayed grade Ⅱ HC after hydration, alkalization, diuretic, hemostatic, anti-graft-versus-host disease (GVHD), and ganciclovir antiviral therapy. The HC patients cured at 35 d. The remaining patients did not suffer HC. Adverse effects such as acid-base balance disturbance did not appear clear. Conclusion Mesna joint hydration, forced diuresis and alkalization was effective and safe to prevent HC.

OBJECTIVE:To provide reference for further improving negotiation mechanism of drug medical insurance in Chi-na. METHODS:Questionnaire investigation was conducted among the medical insurance agency and pharmaceutical company staff who participated in drug medical insurance negotiation in Jiangsu province,Jiangxi province,Qingdao,Chengdu. Their business fa-miliarity and recognition of the negotiating mechanism were also investigated. The descriptive analysis,independent sample t test and other methods were adopted to analyze the data statistically. RESULTS:A total of 70 questionnaires were distributed and 68 val-id questionnaires were collected with effective recovery rate of 97.14%. Respondents included 21 staff members of medical insur-ance agencies and 47 of pharmaceutical companies. In terms of business familiarity,the average score of respondents in all aspects was greater than 3(4 points system),the lowest score wasmanagement of the implementation of drug negotiation projects. There were statistical significances in scores of 3 items between 2 parties in the negotiation(P<0.05):basic principles of the drug negotiation process should be followednegotiation objectives in the substantive negotiation process total score of busi-ness familiarity. The scores of respondents in pharmaceutical companies were higher than those of health insurance agencies. In the recognition of the negotiating mechanism,average score of each survey item was ≥4(5 points system)in the recognition of the overall effect of the negotiation mechanism except forwhich is conducive to maintaining the price system of pharmaceutical com-panies. The average score of all aspects of preparation of the negotiations,substantive negotiation,implementation of the negotia-tion agreement and negotiation project's supervision and evaluation was >4 except forpatients taking drugs is quick and easy. There was no statistical significance between 2 types of respondents in all aspects of overall effect of the negotiation mechanism, preparation of the negotiations and negotiation project's supervision and evaluation(P>0.05). But in the recognition of the substan-tive negotiation,there was statistically significance between 2 types of respondents innegotiations between the two sides in an equal,cooperative,harmonious atmosphere(P<0.05). Healthcare agencies'respondents had higher scores than pharmaceutical companies'ones. And in the recognition of the implementation of the negotiation agreement,there was statistical significance be-tween 2 types of respondents in theafter the agreement entered into force,the medical insurance agency will be strictly in accor-dance with the agreementandfund pay to pharmaceutical companies timely and reasonable(P≤0.05). Healthcare agencies're-spondents have higher scores for than pharmaceutical companies'ones. CONCLUSIONS:The current drug medical insurance nego-tiation mechanism shows good overall effect and runs smoothly. But there are still some shortages,such as collected information the preparation stage is not sufficient;the procedures of patients taking the drug is complicated;negotiating parties do not have equal status;the fund is not paid to the pharmaceutical enterprise timely;evaluation is not perfect.

Objective: To explore the expression changes of transmembrane tumor necrosis factor receptor in rats with multiple organ dysfunction syndrome(MODS). Methods: Thirty two healthy male SD rats were randomly divided into 2 groups. Sixteen rats (MODS group) were subjected to two hit to establish MODS model, the other 16 rats (control group) were without any intervention. RT PCR and immunohistochemistry methods were applied to detect the expression of mTNFR 1 at the levels of mRNA and protein. Results: mTNFR 1 was expressed in normal liver, lung and kidney whereas the most abundant expression was found in liver. Compared with normal liver tissue, the expression of mTNFR 1 in MODS group was significantly higher ( P 0.05). Serum concentration of ALT had correlation with mTNFR 1 gene expression level in liver,but no correlation existed between serum concentration of BUN and mTNFR 1 gene expression level in kidney. Conclusion: The expression of mTNFR 1 increases after the occurence of MODS, which indicates that the impact of TNF can be modulated at the level of receptor.
