Objective To investigate the feasibility and value of combined administration of rapamycin and low dose of cyclosporin A in kidney transplantation recipients. Methods Twenty-five recipients who received their kidney transplantations for 2 months to 10 years were transferred to a new immunosuppression regimen of combined administration of rapamycin,low dose of cyclosporin A and prednisone. During the clinical observation,the average serum trough level of cyclosporin A was maintained between 0.042 and 0.083 μmol/L,and the average serum trough level of rapamycin was controled to 4～8 μg/L. Meanwhile, the dosage of immunosuppressive drugs was adjusted properly according to the white blood cells counting,liver function,blood lipid level and clinical settings.Twenty-five kidney transplant recipients with usual immunosuppression regimen of cyclosporin A in combination with MMF and prednisone served as controls. Results Druing a follow-up period of 2 to 8 months,no acute rejection events were found in this group. All the recipients survived well with functional renal grafts. Two patients in the experimental group quitted during the follow-up. One was incurred to serious pulmonary infection diagnosed as cytomegalovirus infection,and another was sufferred from persistent unknown fever. Other main adverse effects included leucopenia, hyperlipemia and dental ulcer,similarly as control group. No significant abnormal liver function event was found in this group. Conclusions This new immunosuppression regimen of combined administration of rapamycin,low dose cyclosporin A and prednisone in kidney transplantation recipients could avoid or diminish the adverse and toxic effects of calcineurin inhibitors,mainlain well-functional allografts and not increase the incidence of severe untoward reactions. Meanwhile,the costs for taking medicine were also significantly reduced with this regimen. Therefore,it would be an ideal and optimal immunosuppressive maintainence regimen.

Objective To investigate the changes and relationships between the serum endogenously produced interleukin-10(IL-10),nitric oxide synthase(NOS) and inducible nitric oxide synthase(iNOS) in acute myocardial ischemia and reperfusion.Methods Forty-two rats were randomly divided into two groups: myocardial ischemia and reperfusion group(the control group) and methylprednisolone treatment group.The rats in the control group and methylprednisolone treatment group received intravenous injection of placebo and methylprednisolone before ischemia respectively.The plasma IL-10,NOS and iNOS were detected at 0.5 h after ischaemia and 0.5h,2 h after reperfusion,respectively.Result The plasma IL-10,NOS and iNOS gradually increased at 0.5 h after ischaemia and 0.5h,2 h after reperfusion in the two groups.The levels of plasma IL-10 were significantly higher in the methylprednisolone treatment group in different time points than those in the control(all P

Objective To analyze the outcomes of renal transplantation from donation after citizen death (DCD) in our single center.Method We retrospectively investigated the recipient outcomes of renal allografts from DCD.Between November 2010 and 31st December 2014,our institution performed 242 renal transplants from DCD.Outcome variables (survival of recipients/allografts and adverse events) and characteristics of marginal donor transplants were analyzed.Result There were 139 males and 44 females in the enrolled 183 donors,and the range of age was from 2 days to 68 years.183 donors included 102 cases of donation after brain death (category Ⅰ),22 cases of donation after circulatory death (category Ⅱ) and 59 cases of donation after brain death followed by circulatory death (category Ⅲ).Utilizing these renal allografts,we performed 242 kidney transplantations including 237 single kidney transplants and 5 pediatric en bloc kidney transplants.The age of recipients ranged from 12 to 64 years.The data indicated that the 1-year recipient/allograft survival rate was 93.8％ and 90.5％,respectively.The rate of delayed graft function (DGF) was 33.1 ％,higher than that from executed prisoners allografts (23.6％,P＜0.05).However,the rate of 1-year acute rejection,interstitial pneumonia and the other adverse events (urinary fistula,ureteral obstruction and cardiac and cerebral vascular accident,etc.) was similar to that from executed prisoners allografts.In addition,good results from pediatric and elder donor renal transplantation were shown in our data,even though the discard rate of elder donor kidney was high.Conclusion By comprehensive evaluation,strictly screening donors and enhancing the rnanagenent of donors,the long-term survival of recipients may be prolonged and the incidence of DGF and primary graft non-function (PNF) may be decreased.The marginal donors from pediatric and elder DCD donors could be utilized in clinical transplantation safely and effectively as long as reasonable evaluation was carried out.

AIM: To evaluate the repeatability and reproducibility of thickness profile measurement of intra-retinal layers determined by an automated algorithm applied to OCT images from Cirrus optical coherence tomography (OCT) instrument.METHODS: In this prospective cross-sectional study,retinal thickness images at 6mm×6mm around fovea were obtained from 86 eyes of 43 normal subjects with Cirrus HD-OCT instrument.The retinal images from patients were analysis by Cirrus automated algorithm GCA software,including ganglion cell layer and inner plexiform layer(GCIPL).During this study,operator A would make 2 times measurements to all patients,after that operator B would make another 2 times measurements by Repeat scan model.All the data,including GCL average thickness,min thickness,12 clock average thickness,2 clock average thickness,4 clock average thickness,6 clock average thickness,8 clock average thickness and 10 clock average thickness were measured by SPSS 15.0 software.Standard deviation (SD),coefficient of variation (CV) and interclass correlation coefficient (ICC) were calculated from the results of three-times tests by different examiner to evaluate the repeatability and from the results of two different examiners to assess the reproducibility.Written informed consent was obtained from each subject prior to any medical procedure.RESULTS: The average GCIPL thickness of OD was 85.12±3.95μm;the minimum average GCIPL thickness was 83.21±4.41μm;the standard deviation of OD in clock map was from 3.79μm to 4.84μm;CV(95%CI) was between 0.26 and 0.93;ICC was from 0.939 to 0.989.The average GCL+IPL thickness of OS was 84.65±8.73μm;the minimum average GCPL thickness was 81±13.08μm;the standard deviation of OS in clock map was from 8.24μm to 10.56μm;CV(95%CI) was between 0.92 and 4.94;ICC was from 0.264 to 0.968.CONCLUSION: Cirrus HD-OCT GCA software with automated algorithm can offer accurate and repeatable thickness profile of OCT retinal image.GCA is a useful and reliable approach to the measurement of intra-retinal layer thickness,which may improve the diagnosis and monitoring of retinal diseases.

Abstract: Objective To understand the distribution and drug resistance of pathogenic bacteria of bloodstream infection in Fujian Province, and to provide reference for clinical rational drug use. Methods Bacteria identification and antimicrobial susceptibility test were carried out on the isolated strains of blood culture samples in 31 medical institutions in Fujian Province according to the unified plan. The data were statistically analyzed by WHONET 5.6 software according to the Clinical and Laboratory Standards Institute (CLSI) drug sensitivity executive standard in 2021. Results After removing the duplicate strains, 10 356 strains of bacteria were collected, including 3 668 strains of Gram-positive bacteria (35.4%) and 6 688 strains of Gram-negative bacteria (64.6%). The top 5 bacteria are Escherichia coli, Klebsiella pneumoniae, coagulase negative Staphylococcus, Staphylococcus aureus and Pseudomonas aeruginosa. In this study, the detection rate of methicillin-resistant Staphylococcus aureus (MRSA) was 24.5%, and the detection rate of methicillin-resistant coagulase-negative Staphylococcus aureus (MRCNS) was 76.8%. Vancomycin, teicoplanin and linezolid resistant staphylococci were not found. The detection rate of penicillin resistant Streptococcus pneumoniae was 3.2%. Vancomycin resistant Enterococcus faecalis and Enterococcus faecium were 0.8% and 1.1% respectively. The resistance rate of Escherichia coli to carbapenems was 0.8%, and the resistance rate to levofloxacin was 41.9%; the resistance rate of Klebsiella pneumoniae to carbapenems was 15.0%. The resistance rate of Acinetobacter baumannii to carbapenems was 45.1%; the detection rate of Pseudomonas aeruginosa was only 14.2%, and it maintained a high sensitivity to most drugs. Conclusions Most bloodstream infections in Fujian Province are caused by Escherichia coli, Klebsiella pneumoniae and Staphylococcus. The drug resistance of some strains is not optimistic, so we should continue to strengthen the clinical application management of antibiotics and use them correctly and reasonably.

Measuring the content of soluble reducing sugar, total sugar, soluble protein, guanosine, alkaloids, and succinic acid of Pinellia ternata tuber were measured by anthrone-sulfuric acid colorimetric method, Coomassie brilliant blue method, RP-HPLC, reverse potentiometric titration, acid dye colorimetry, respectively. The result showed that yellow light could promote the growth and development of P. ternata and increase the content of soluble reducing sugar, total sugar, alkaloids, and succinic acid. Under blue light could promote the content of soluble protein and guanosine. Red and yellow light increased the content of chlorophyll a and chlorophyll b, contrastively blue light reduced the content of chlorophyll a and chlorophyll b. White film through the most uniform spectrum was most conducive to the synthesis of chlorophyll a. As single film, blue film, yellow film were more conducive to the synthesis of chlorophyll a, green film and red film had been relatively beneficial to the synthesis of chlorophyll b. Bulbil formed the largest number and the biggest propagation coefficient of P. ternata under red light showed that it could increase the production of P. ternata under red light.

OBJECTIVETo explore the effect of total flavonoids of Herba Epimedium (FHE) on BMP-2/RunX2/OSX signaling pathway in promoting osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs).

METHODSPassage 3 BMSCs were randomly divided into the control group, the experimental group, and the inhibitor group. BMSCs in the control group were cultured in 0.2% dimethyl sulfoxide + Osteogenuxic Supplement (OS) fluid + DMEM/F12 culture media. BMSCs in the experimental group were intervened by 20 microg/mL FHE. BMSCs in the inhibitor group were intervened by 20 microg/mL FHE and 1 microg/mL NOGGIN recombinant protein. At day 9 alkaline phosphatase (ALP) activity was measured. Calcium nodules were stained by alizarin red staining and the density was observed. The transcription expression of osteogenic differentiation-related proteins (type I collagen, osteocalcin, and osteopontin) and related factors of BMP-2/RunX2/OSX signaling pathway was assayed by RT-PCR.

RESULTSCompared with the control group, ALP activities were enhanced and the density of calcium nodules significantly increased; type I collagen, osteocalcin, and osteopontin expression levels were increased in the experimental group. The expression of osteogenesis-related transcription factor was also increased in the experimental group. Noggin recombinant protein inhibited FHE promoting BMSCs osteogenesis in the inhibitor group. Compared with the experimental group, ALP activity decreased (P < 0.05), the density of calcium nodules was lowered, expression levels of type I collagen, osteocalcin, osteopontin significantly decreased (P < 0.05) in the inhibitor group.

CONCLUSION20 microg/mL FHE promoted osteogenic differentiation process of BMSCs by BMP-2/RunX2/OSX signaling pathway.
