Objective To explore the correlation of mycoplasma pneumoniae infection with frequent relapses of steroid-sensitive nephrotic syndrome (SSNS) in children.Methods 35 patients with relapse of SSNS and acute respiratory tract infection were divided into a observation group (mycoplasma pneumoniae infection) and a control group.The clinical and laboratory data including 24 h urine protein (24 h-Upro),urea nitrogen (Bun),serum creatinine (Scr),albumin (Alb) and cholesterol (Chol) were analyzed before and after treatment.Results The clinical and laboratory indexes were obviously improved after treatment,the difference was statistically significant (P ≤ 0.01).24 h-Upro decreased more significantly in the observation group than in the control group after treatment.In the observation group,15 of 18 children achieved the efficacy,9 of whom had complete response and 6 had partial response.In the control group,14 patients achieved the efficacy,6 of whom had complete response and 8 had partial response.Conclusions After treatment,most of the children with frequent relapses of steroid-sensitive nephrotic syndrome induced by cute respiratory infection are relieved.Proteinuria,hypoproteinemia,hyperlipidemia,and renal function were improved in those patients.Therapies with azithromycin achieves a more marked efficacy.

Objective To investigate the effect of creatine phosphate on perioperative myocardial injury caused by living donor liver transplantation(LDLT)in adult patients.Methods Forty ASA Ⅱ -Ⅳ patients(liver function Child-Pugh grade B or C)aged 45-62 yr weighing 47-91 kg undergoing LDLT were randomly divided into 2 groups(n = 20 each): control group(group C)and creatine phosphate group(group CP).In group CP,creatine phosphate 30 mg/kg was injected intravenously at skin incision followed by creatine phosphate infusion at 4 mg· kg- 1 · h- 1 until the end of surgery.In group C,equal volume of normal saline was infused instead of creatine phosphate.HR,MAP,CVP,PCWP,CO and SvO2 were recorded immediately before skin incision,at 5 and 30 min of anhepatic phase,at 5 and 30 min of neohepatic phase and at the end of operation.Blood samples were taken from central vein immediately before skin incision(baseline,T0),at 30 min of anhepatic phase(T1),at 30min of neohepatic phase(T2),at the end of operation(T3)and at 4 and 24 h after operation(T4,5)for determination of serum cardiac troponin I(cTnI)and creatine kinase MB(CK-MB)concentrations and lactate dehydrogenase(LDH)activity.Postoperative adverse events were recorded.Results The serum cTnI and CK-MB concentrations and LDH activity were significantly increased at T2-5 as compared with the baseline value at T0 in both groups(P ＜0.05 or 0.01).MAP and CO were significantly higher from 5 min of neohepatic phase to the end of operation,the serum cTnI and CK-MB concentrations and LDH activity were significantly lower at T2-5,and the incidence of ventricular arrhythmia was significantly lower in group CP than in group C(P ＜ 0.05 or 0.01).Conclusion Creatine phosphate can attenuate perioperative myocardial injury caused by LDLT in adult patients.

Objective To evaluate the safety, feasibility and curative effect of mini-incision ex-ploration of common bile duct. Methods In this study, 290 patients underwent min-incision explora-tion of common bile duct and 120 patients underwent open-incision exploration of common bile duct for bile duct stones and/or gallstones from 2005 to 2007. The iatrogenic bile duct injury, postoperative complication, residual stone, stone recurrence,therapeutic effect and clinical data were evaluated by randomized contrast analysis. Results Time of operation, bleeding, volume of drain pipe, time of re-covery of intestinal peristalsis and average duration in hospital were significantly lower in the group of min-incision exploration(MCE) than in the group of open-incision exploration(OCE). The iatrogentic bile duct injury occurred in 5 cases(1.72%), residual stone in 10 cases(3.45%), stone recurrence in 15 cases(5.18%) in the group of MCE, and in 2 cases(1.67%), 4 cases(3. 33%) and 6 cases respec-tively in the group of OCE. There was no marked difference between the two groups. Howevert post-operative complications occurred in 17 cases(6.8%) and 16(13.3%) in the group of MCE and OCE,respectively. There was remarkable difference between the 2 groups(P<0. 05). Conclusion Mini-in-cision exploration of common bile duct is a feasible and safe method resulting in fewer complications of iatrogentic bile duct injury, stone recurrence and residual stone.

OBJECTIVE:To explore the basic principles,advantages and application prospects of Bayesian mixed treatment comparison (MTC),and provide theoretic support for making reasonable decisions of pharmacoeconomics. METHODS:The prob-lems existing in model and method that had been used in the study of pharmacoeconomics as starting point,literature research was used to sort out the domestic development and applications of MTC and study its application and development prospect. RESULTS &CONCLUSIONS:The evaluation methods of pharmacoeconomics play an important role in selection of essential medicines,medi-care insurance directory medicines,basic health and basic public health programs,the results directly affect the total effective rate of medical resources’configuration. The current research models cannot effectively solve the problem,for example,decision tree model is difficult to make evaluation of long-term treatment;Markov model and the use of multiple attribute utility theory are restricted by the model parameters;discrete event simulation is limited because it depends on the epidemiological study and clinical trial. MTC, an extension approach of the traditional Meta-analysis,is an effective new method developed recently to analyze and compare the di-rect or indirect evidence of several different clinical treatment factors in order to make a comprehensive evaluation of the various inter-ventions in the absence of evidence support. So the MTC can make up for the limitation of current evaluation methods.

AIM To investigate whether tubeimosides induce apoptosis in CNE-2Z. METHODS Growth inhibition by tubeimosides was measured using MTT assay. The effect of tubeimosides on apoptosis induction of CNE-2Z cell line was studied by the fluorescent microscopy, electronic microscopy, DNA agarose gel electrophoresis, flow cytometry analysis. Western blotting was performed for detecting the apoptosis-related gene. RESULTS The growth of CNE-2Z cells was inhibited obviously by tubeimosides. CNE-2Z cells showed typical apoptotic features observed by fluorescent microscopy, electronic microscopy. DNA fragmentation into multiples of low molecular weight DNA(180～200 bp) was detected by agarose gel electrophoresis of DNA; Sub-G 1 peak was found by flow cytometry analysis, and the apoptosis index was 58 0%. The expression of bcl-2, inhibitor of apoptosis, decreased apparently; while that of bax, inducer of apoptosis, increased notably at 1, 3, 5 h after the addition of tubeimosides. The cleavage of caspase-3 was noticed at 1, 3, 5 h after the treatment of tubeimosides. CONCLUSION Tubeimosides could induce the apoptosis of CNE-2Z cells. The induction of apoptotic by tubeimosides was closely associated with bcl-2, bax and caspase-3.

Objective To compare the body weight,height,head circumference of premature babies fed by different ways,and to analyze the advantages and disadvantages.Methods 260 premature infants were selected as the research subjects,according to random number table,they were divided into four groups.Group A:premature infant formula feeding,80 cases;Group B:pure breast feeding group,60 cases;Group C:normal full term formula feeding,60 cases;Group D:premature infant formula mixed breast feeding,60 cases.All children were fed at the first 12 to 24h after birth.The body weight,height,head circumference and catch up full term time were evaluation index. Results After correct gestational age 40 weeks,group B children'weight,height,head circumference were higher than other groups,group C was the lowest levels,the difference was statistically significant (F =3.563,P <0.05).Correct gestational age 1,3,6 months later,group A children'weight,height and head circumference index were higher than other feeding group,the level of group D was the second,the lowest level was group C,the differences were statistically significant (F =3.011,2.853,2.779,all P <0.05).In 6 months,group A,38.8% (31 /80),was the fastest one to reach the full term infant,the difference was statistically significant (χ2 =29.149,P <0.05).At other time,the pur-suing number of group A was bigger,but there was no statistically significant difference.Conclusion For premature babies,preterm infant formula milk powder or premature infant formula and milk feeding way is better than that of pure breast feeding and normal full term milk powder,which can guarantee the children's nutrition demand,shorten the time of pursuing full term infant,promote baby's health.
