Objective To summarize the short-term results of simultaneous pancreas-kidney transplantation (SPK) at a single center in China.Methods SPK was performed on 12 consecutive patients from Jan.2010 to July 2014.All patients had long-standing insulin-dependent diabetes mellitus (IDDM) and subsequent renal failure.Bladder drainage (BD) of exocrine secretion was used in the 10 cases and enteric drainage (ED) in 2 patients.The patients were treated with quadruple therapy,which included ATG or anti-CD25 monoclonal antibody induction therapy,prednisone,tacrolimus and mycophenolat-mofetil (MMF).Results The SPK was performed successfully in 10 cases.One patient accepted re-pancreas transplantation due to necrotizing pancreatitis.One patient suffered hemorrhage of bladder,accepted 3 times of embolization therapy and died due to lung infection.Ten patients achieved excellent renal function and euglycemia,and no further insulin treatment was given in 9.5 ± 4.2 days posttransplant.Fasting plasma glucose returned to normal in 14.2 ± 5.1 days.Serum creatinine returned to normal in 10.4 ± 6.5 days.The mean hospital stay was 21.4 ± 7.3 days.One biopsy-proven renal rejection episodes occurred in 14 days postoperation.Main complications included wound infections on the side of pancreatic graft,lymphorrhagia,tacrolimus toxicity and urinary tract infection.Conclusion SPK is an effective therapy of ESRD.Donated graft protection system foundation,refinement and individualized treatment posttransplantion may be the key factors for successful SPK.

OBJECTIVETo investigate the role of microRNA-34a (miR-34a) in regulating the cell cycles of bladder cancer cell line J82 and explore the underlying mechanism.

METHODSJ82 cells were transfected with a miR-34a mimic or an inhibitor to induce miR-34a overexpression or silencing. The RNA level of miR-34a in the transfected cells was detected by real-time PCR, and CD44 expressions at the mRNA and protein levels were detected by real-time PCR and Western blotting. Luciferase reporter assay was used to detect the activation of 3'UTR of CD44, and flow cytometry was performed to analyze the cell cycle changes.

RESULTSThe expression level of miR-34a was significantly increased and CD44 expression significantly lowered in cells transfected with miR-34a mimic; miR-34a inhibitor transfection caused reverse effects on miR-34a and CD44 expressions. MiR-34a mimics downregulated while miR-34a inhibitor enhanced the activation of 3'UTR of CD44 with corresponding changes in the expressions of some cell cycle-related proteins. MiR-34a mimics and miR-34a inhibitor induced opposite changes in J82 cell cycle, which were partly reversed by CD44.

CONCLUSIONMiRNA-34a regulates cell cycles by targeting CD44 in human bladder carcinoma cell line J82.

Objective To investigate the reliability and validity of the medical outcomes by applying short form-36 (SF-36) in evaluating gout patients’ health related quality of life (HRQOL).Methods Gout patientswere enrolled between March 2016 and June 2016 in Foshan Hospital of Traditional Chinese Medicine.Patients completed the SF-36 questionnaire.Summary scores,physical component summary (PCS) and mental component summary (MCS) were calculated by summing factor-weighted scores across all 8 subscales,with factor weights derived from general population.The indicators of reliability and validity included internal consistency,test-retest reliability,structural and discriminant validity,ceiling and floor effect.Results Totally 306 patients were enrolled.The internal consistency test showed that the Cronbach α coefficients ranged from 0.782 to 0.822,and the test-retest reliability coefficients ranged from 0.720 to 0.986 (P＜0.01).Structural validity analysis showed that there were two items whose eigenvalues were greater than one with the cumulative contribution rate of 66.1％.The discriminant validity analysis found that patients with more numbers of tophi,higher frequency of flare,multi-arthrosis involved and more complications had less scores of PCS and MCS (P＜0.05).There was a high ceiling effect on physiological function and a higher ceiling and floor effect on role limitation and emotional function caused hy impaired physical health.Conclusion The SF-36 can be used for the assessment of HRQOL in Chinese gout patients but disease specific questionnaire are warranted.

Objective:To investigate the safety, efficacy and application indication of intra-operative cell salvage (IOCS) in cesarean section.Methods:A total of 1 265 pregnant women who received IOCS blood transfusion during cesarean section in 11 tertiary A hospitals from August 2016 to January 2019 were collected and divided into <1 500 ml group (796 cases) and ≥1 500 ml group (469 cases) according to the amount of blood loss during cesarean section. The general clinical data, ultrasonic imaging data, perinatal and puerperium indicators were analyzed retrospectively. The risk factors of intraoperative blood loss ≥1 500 mL using IOCS transfusion were analyzed by logistic multivariate regression.Results:(1) A total of 848 001 ml of blood was recovered and a total of 418 649 ml of blood was transfused in 1 265 pregnant women who received IOCS transfusions, which was equivalent to 23 258 U red blood cell suspension, greatly saving medical resources. The intraoperative blood loss in <1 500 ml group and ≥1 500 ml group was 800 ml (300-1 453 ml) and 2 335 ml (1 500-20 000 ml), respectively. No amniotic fluid embolism, severe adverse reactions, shock and death occurred in the two groups. (3) Multivariate regression analysis showed that age ≥35 years ( OR=1.5, 95% CI: 1.1-1.9), prenatal hemoglobin level <110 g/L ( OR=1.7, 95% CI: 1.3-2.2), history of uterine surgery ( OR=1.8, 95% CI: 1.3-2.6), placenta previa ( OR=1.9, 95% CI: 1.1-3.1), placenta accreta ( OR=2.6, 95% CI: 1.8-3.9), blood pool in the placenta ( OR=1.6, 95% CI: 1.1-2.3), abnormal posterior placenta muscle wall ( OR=1.8, 95% CI: 1.2-2.6), placenta projecting to the anterior uterine wall ( OR=3.0, 95% CI: 1.3-7.0) were risk factors for blood loss ≥1 500 ml in obstetric transfusion using IOCS technique, with statistical significance (all P<0.05). Conclusion:IOCS is safe and effective in cesarean section, which could save the medical resources and reduces medical expenses, however, it is necessary to strictly master the application indication.

Due to the availability of 18F-FDG in PET centers, this article aims to advocate and promote the standardization of 18F-FDG PET brain imaging in dementia in order to improve the reliability, repeatability and comparison of the imaging process and results. It is also provided to guide the PET imaging operation standard and to give suggestions on image interpretation.
