Objective To summarize the clinical data of renal transplants survived with graft function more than 10 years and the adverse events during this period, and to discuss the main strategies for the long-term survival Methods Survival rate of renal transplants simultaneously survived with graft function > 10 years and grafts was counted respectively in total 1003 renal transplant recipients at our hospital before Dec. 31,1998 retrospectively. Their relevant survival,adverse events and initial post-operative immunosuppressive regimens were recorded simultaneously.Results As of Dec. 31, 2008, the 10-year survival rate of recipients was 62. 7% (629/1003), and recipients with graft function accounted for 85. 37 % (537/629). Of them, 94. 75 % (596/629) recipients received cyclosporine A (CsA) -based immunosuppression plus other antiproliferative immunosuppressive agents. Post-transplantation adverse events included coronary heart diseases in 57 cases (9. 06 %), liver damage in 32 cases (5. 09 %), malignancy in 29 cases (4. 61% ), diabetic mellitus in 25 cases (3. 97 %), apoplexy in 16 cases (2. 54 %), severe bone marrow depression in 14 cases (2. 23 %), femur head necrosis in 7 cases (1.11%), lower-extremity thrombosis in 3 cases (0. 48 %), sudden deafness in 2 cases (0. 32 %). There were 690 survival patients and 49 deaths including 19 (38. 78 %) due to cardiocerebral vascular accidents, 10 (20. 41%) due to malignancy, 9 (18. 37 %) due to hepatic failure, 4 (8. 16 %) due to infection, 3 (6. 12 %) due to treatment abandonment, 2 (4. 08 %) unknown reasons and 2 (4. 08 %) accidental deaths. Conclusion Long-term survival after renal transplantation is associated with the primary medication of CsA as the main immunosuppressive regimen. The non-immunologic factors such as the prevention and cure of cardioeerebral vascular diseases and the early finding of liver functional abnormality and tumor are the main points focused during follow-up.

OBJECTIVE To investigate the effect of arctigenin(ATG) on liver fibrosis in rats induced by carbon tetrachloride(CCl4)and to explore its underlying mechanism. METHODS Sprague-Dawley rats were randomly divided into six groups:vehicle,ATG 3.0 mg · kg-1 group,CCl4 model group,CCl4+ATG 1.0 and 3.0 mg·kg-1 groups,and CCl4+colchicine(COL)0.1 mg·kg-1(toxicity)group. Liver fibrosis was induced by subcutaneous injection of CCl4 in rats for 8 weeks. ATG and colchicine were administrated ig once a day starting from the fifth week after the CCl4 treatment for 4 weeks subsequent. At the end of the study,glutamic pyruvic transaminase (GPT),glutamic oxaloacetic transaminase(GOT),albumin(ALB),and total bilirubin (TBIL) as well as the contents of hydroxyproline (HYP) in liver tissues were measured. Histopathological changes were observed in the liver tissues using hematoxyline-eosin(HE)and Masson’s trichrome staining. The proliferation of hepatic stellate cells (HSC) and expression of cell cycle-related proteins were assayed by indirect immunofluores?cence staining and Western blotting,respectively. RESULTS Compared with CCl4 model group,ATG 1.0 and 3.0 mg · kg-1 improved the liver function by decreasing serum contents of GPT,GOT and TBIL (P<0.05),and increasing serum content of albumin(P<0.05). Histological results indicated that ATG 1.0 and 3.0 mg · kg-1 alleviated liver damage and reduced the formation of fibrous septa. Moreover, ATG 1.0 and 3.0 mg · kg-1 significantly decreased liver HYP when compared with CCl4 model group(P<0.05). In addition,CCl4-induced proliferation of activated HSC was inhibited by ATG 1.0 and 3.0 mg·kg-1, and this was accompanied by down-regulation of cyclin D1,cyclin-dependent kinase(CDK)2,CDK4, and proliferating cell nuclear antigen (PCNA)(P<0.05),and up-regulation of p27kip1 in activated HSC (P<0.05). CONCLUSION ATG can alleviate hepatic injury and fibrosis induced by CCl4,which is probably associated with suppression of the proliferation of activated HSC.

ObjectiveTo investigate the treatment efficacy of traumatic proximal interphalangeal (PIP)joint defects with prosthetic replacement.MethodsFrom September 2007 to November 2010, ten patients with joint defect injuries were treated by joint prosthetic replacement (5 index fingers,4 middle fingers,and 1 ring finger),including a reconstructed middle finger.Joint motion range and postoperative pain of all cases were measured to evaluate the treatment.ResultsAll cases went through a smooth operation with primary wound healing,and with neither intraoperative nor postoperative complications happened.The follow-up period was range from 8 months to 2 years.The active motion arcs of PIP joints ranged from 50° to 80°,and satisfactory appearances as well. According to assessment standard of upper extremity described by Chinese Hand Surgery Association,the treatment outcome were excellent in 6 fingers,good in 3 fingers,general in 1 finger.ConclusionJoint prosthetic replacement is a new effective method to treat traumatic proximal interphalangeal joint defect,which is a simple operation with advantages of little trauma and rapid recovery.

Objective: To investigate the intervention effect of electroacupuncture on post-withdrawal anxiety and depression of those with heroin dependence. Method: One hundred and twenty heroin dependence cases were randomly allocated into 4 groups, including acupuncture group 1 using Jiaji (Ex-B 2) points and Shenshu (BL 23), acupuncture group 2 using points in the four limbs, simulation and control groups. Then the SAS and SDS changes were observed before the treatment and 4th, 8th and 10th week after. Result: At the 4th, 8th and 10th week, the SAS and SDS scores in acupuncture group 1 and 2 showed significant differences with the control group (P<0.01, P<0.05). There were significant differences between SAS changes in acupuncture group 1 and 2 but there was no significant difference in SDS changes. Conclusion:Electroacupuncture can improve the post-withdrawal anxiety and depression in heroin addicts.Jiaji (Ex-B 2) points showed significantly better effects in improving anxiety than points in four limbs but no significant difference in improving depression.

Chronic kidney disease (CKD) is a serious chronic disease with high incidence, poor prognosis, and a variety of complications. Indoxyl-sulfate (IS) and p-cresol sulfate (PCS) are two typical gut-derived uremic toxins, which are produced by the co-metabolism of intestinal microbes and the host. With the progression of CKD, gut-derived uremic toxins such as IS and PCS accumulate in patients with CKD and thereafter accelerate the progression of CKD. Gut microbiota is closely related with CKD, and targeting gut microbiota to regulate gut-derived uremic toxins synthesis and metabolic pathways may be a promising strategy to delay the progression of CKD. In this paper, the relationship between gut microbiota, gut-derived uremic toxins, and CKD was analyzed, and the strategy to delay the progression of CKD by targeting gut microbiota and uremic toxins metabolism pathway was proposed.

Although the essential oil of Xiangfu Siwu decoction (XFSWD) has strong pharmacological activity, its special physical and chemical properties restrict the clinical application and curative effect. In this paper, Xiangfu Siwu decoction essential oil (XFS-WO) was prepared by forming inclusion complex with β-cyclodextrin (β-CD). The present study is to investigate the effect of β-CD inclusion complex on the transport of major components of XFSWO using Caco-2 cell monolayer model, thus to research the effect of this formation on the absorption of drugs with low solubility and high permeability, which belong to class 2 in biopharmaceutics classification system. A sensitive and rapid UPLC-MS/MS method was developed for simultaneous quantification of senkyunolide A, 3-n-butylphthalide, Z-ligustilide, dehydrocostus lactone and α-cyperone, which are active compounds in XFSWO. The transport parameters were analyzed and compared in free oil and its β-CD inclusion complex. The result revealed that the formation of XFSWO/β-CD inclusion complex has significantly increased the transportation and absorption of major active ingredients than free oil. Accordingly, it can be speculated that cyclodextrin inclusion complex can improve bioavailability of poorly water-soluble drugs. Above all these mentioned researches, it provided foundation and basis for physiological disposition and pharmaceutical study of XFSWD.

Modern drying technology was used to explore suitable drying process to provide scientific basis for improving drying processing methods of Scrophulariae Radix. Controlled temperature and humidity drying, vacuum drying apparatus, microwave vacuum drying apparatus, short infrared drying device were used to gain samples for analyzing. The character appearance, concentration of main components and power consumption indicators were chosen for preliminary judging. Six major components, including iridoids and phenylpropanoids were analyzed by UPLC-MS/MS method. The contents of polysaccharides were determined by UV-visible spectrophotometry. The character appearance with controlled temperature and humidity drying and short infrared drying meet the pharmacopoeia standard (Ch. p, edition 2015), while samples with vacuum and microwave vacuum drying apparatus didn't. Compared to fresh sample, concentrations of harpagide, harpagoside, aucubin and catalpol were lower in the dried samples. Angoroside-C showed no significant change before and after drying. Concentration of acteoside increased after drying. Samples with controlled temperature (70 degrees C) and humidity (15% - 10%) drying had high content and short drying time. The better drying process of Scrophulariae Radix was controlled temperature and humidity drying. The method will provide the reference for the drying technology standard of roots medicine.

Objective To explore the possible relationship between environmental contamination by Aspergillus and invasive aspergillosis.Methods From November 2005 to October 2006,samples were collected from the environment (air in corridors,air in wards,surfaces and tap water) twice a month,and from patients (nose,pharynx and sputum) at a liver transplantation department (LTD),neurologic surgery intensive care unit (NSICU) and central intensive care unit (CICU) in our hospital,and subjected to fungal culture.The Aspergillus density was determined in these environments.The isolates of Aspergillus flavus were genotyped by random amplification of polymorphic DNA (RAPD) assay to investigate the origin of infection.Results The mean aspergillus density was 12,10.75,0 and 20 cfu/m~3 at LTD,NSICU,CICU and corridors respectively.The five most prevalent species of aspergillus in these environments in decreasing order were Aspergillus flavus,Aspergillus fumigatus,Aspergillus niger,Aspergillus versicolor and Aspergillus clavatus.RAPD demonstrated that the genotypes ofA.flavus isolated from two patients were identical to those of the environmental strains in NSICU.The A.flavus genotypes from 3 patients in CICU were all different from those of the environment strains in CICU,but the genotypes were identical from two of the three patients.Conclusions Aspergillus contamination of different degree does exist at LTD,NSICU and CICU. The genotypes of A.flavus are identical from patients and environment in NSICU,suggesting that the clinical infection may originate from hospital environment.
