Objective To evaluate the efficacy of imipenem-cilastin sodium as subsequent therapy on peritoneal dialysis(PD)-related peritonitis.Methods From January 2007 to December 2010,44 PD-related peritonitis patients in our hospital were enrolled in the study.These patients presented cloudy fluid after 3 days initial treatment,and bacterial culture was Gram-negative bacteria or negative.Thirteen peritonitis episodes were treated with ceftazidime,while 36 episodes with imipenem-cilastin sodium.Efficacy,outcome,pathogen and drug-resistance were analyzed retrospectively.Results The effective rates 2 d later of ceftazidime and imipenem-cilastin sodium were 23.1％ and 72.2％ respectively with significant difference (P＜0.05).Gram-negative bacteria of ceftazidime and imipenem-cilastin sodium groups were 69.4％ and 65.2％ respectively without significant difference (P＞0.05).The cure rates 3 weeks later of ceftazidime and imipenemcilastin sodium groups were 23.1％ and 72.2％ respectively with significant difference (P＜0.05).Conclusion As subsequent therapy for PD-related peritonitis,imipenem-cilastin sodium can improve the cure rate.

Aim To study the effects of pioglitazone on the hypertrophic myocardial cells induced with high glucose and high insulin. Methods Using cultured myocardial cells as a model, The protein content was assayed with Lowrys method; The contracting frequency was counted by the inverted microscope;The protein synthesis was assayed with leucine intake method;The cardiomyocytes volumes was measured by computer photograph analysis system; the cellular hypertrophy was observed. Results Compared with verapamil, Pioglitazone significantly inhibited the protein content, cellular protein synthesis and volumes of cultured hypertrophic myocardial cells induced with high glucose and high insulin. Meanwhile pioglitazone and verapamil inhibited myocardial cells contracting frequency too. Conclusions Pioglitazone inhibited cardiac hypertrophy of cultured myocardial cells induced with high glucose and high glucose. The mechanism of the effect of pioglitazone on cardiac hypertrophy needs further study.

AIM:To analyze the cause of hip prosthesis dislocation,so as to prevent the dislocation following total hip arthroplasty(THA).METHODS:Between January 2002 and June 2007,a total of 348 cases(406 hips) received THA in the Department of Orthopaedics,the Second Affiliated Hospital of Fujian Medical University,and 15 patients(15 hips) occurred dislocation(3.7%),including 6 males and 9 females.Their age ranged 35-76 years,with a mean of 58 years.Primary affections consisted of femoral neck fracture in 3 cases(one with dislocation rebuilding after THA),femoral necrosis in 5 cases,hip arthodysplasia in 5 cases,and osteoarthritis in 2 cases.THA was carried out through lateral approach in 8 patients,and posterior lateral approach in 7 patients.The first dislocation occurred in 2 patients within 2 weeks,3 patients during 2-4 weeks,6 patients during 4-6 weeks,3 patients during 6-12 weeks,and 1 patient 12 weeks later.The movement of dislocation occurrence includes moving the patients in 2,turning over in 2,turning around in 4,trying to stand from sitting in 3,sock wearing in 3,and picking up in 2.It was revealed in the clinical analysis and operational incision that anterior dislocation was found in 6 cases,while posterior dislocation in 9 cases;proper placement of prosthesis in 5 cases,while incorrect placement in 10 cases.Close reduction was conducted in short time after dislocation,achieving success in 11 cases.There were 4 cases treated with open reduction after failure of close reduction,and hip joints were restricted.Seven patients were found dislocation again.And four patients prolonged external fixation and 3 patients were performed revision.RESULTS:The follow-up period ranged from 10 to 60 months.Eight cases succeeded the first reduction,with good joint stability and without relapse.Redislocation occurred in 4 cases,and was cured by prolonging fixation.No cases following revision were found dislocation.The average score was(85?5) according to Harris scoring system.There was no biocompatibility between the materials and the host.CONCLUSION:We should emphasize prevention of dislocation in the early THA and enough fixation time after reduction.

Objective To investigate the effect of microRNA-21 (miR-21) antisense oligonucleoti-de on collagen synthesis in the rat hepatic satellite cells ( HSCs) .Methods Rat hepatic stellate cells were isolated and cultured; the miR-21 antisense oligonucleotide was transfected into HSCs with lipofectamine 2000;after incubation 48 h, the HSCs were collected.The expression of miR-21 was detected with reverse transcription polymerase chain reaction ( RT-PCR) , andα-smooth muscle actin (α-SMA) protein in HSCs with Western blot.The cell proliferation was assayed with methyl thiazolyl tetrazolium ( MTT) method.Re-sults Compared to scrambled control group, the expression of miR-21 was reduced by 76%( P <0.01), the proliferation activity of HSCs was reduced by(26 ±3)%( P <0.01), the expressions of type I and III collagen proteins were reduced by(61 ±7)%and (48 ±6)%( P <0.01).Conclusions The miR-21 an-tisense oligonucleotide could reduce significantly the expression of miR-21, and inhibit HSC proliferation and extracellular matrix production.

OBJECTIVETo establish a rapid determination method with gas chromatography-mass spectrometer (GC-MS) for thiodiglycolic acid (TDGA), a vinyl chloride (VCM) biomarker.

METHODSA high- sensitivity determination method was established using a moderate methyl esterification instead of methyl esterification of highly toxic diazo reaction.

RESULTSThe standard curve regression linear equation of the method was: y=8460.5x-4758.2, the linear coefficient was 0.999 7, the minimum quantity concentration was 2.0 µg/L, the range of precision value was 0.81%-2.38%, and the average recovery of standard addition was 99.0%-102.9%.

CONCLUSIONThis method reduces the risk of traditional methyl esterification, improves the determination sensitivity compared with the GC-FPD method, and meets the determination requirement of TDGA.

Objective To investigate the diagnostic value of thyroglobulin measurement in fine-needle aspiration biopsy(FNA-Tg).Methods This study included 63 patients with thyroid cancer or with enlarged lymph nodes during the follow-up from Aug.2010 to Jun.2012.Ultrasound-guided fine-needle aspiration was done in the 63 patients with 79 suspicious enlarged lymph nodes.Then thyroglobulin(Tg) in FNA washout fluid and serum Tg were assayed with electrochemiluminescenceimmunoassay(ECLIA).Diagnostic sensitivity,specificity and area under the ROC curve were evaluated according to 5 predetermined threshold levels:FNA-Tg/serum-Tg ＞ 1,mean + 2SD of node-negative patients,10 ng/ml,optimal operating point of ROC curve and 1000 ng/ml.Results The sensitivity value was 90.70％,90.70％,95.35％,90.70％ and 65.12％ respectively on the 5 threshold level,significantly lower than those on the threshold level of 1000 ng/ml(P ＜0.05).The specificity value was 97.22％,91.67％,72.22％,97.22％ and 100％ (P ＞0.05) on those threshold levels,significantly lower than those on the threshold level of 10 ng/ml (P ＜0.05).The area under the ROC curve was 0.940,0.912,0.838,0.940 and 0.826 respectively.There was no statistical difference(P ＞0.05).Conclusion Selecting FNA-Tg/serum-Tg ＞ 1 as a positive threshold value can be a secondary diagnosis of lymph nodes metastasis in patients with papillary thyroid cancer.
