Objective To investigate the efficacy and safety of anti CD25 Ab (Zenapax;Daclizumab) induction therapy in 62 patients following renal transplantation. Methods Sixty-two renal transplant recipients treated with Daclizumab induction therapy were analyzed retrospectively from Sep. 1999 to May 2004. Main immunosuppressive therapy regimen consisted of steroids cyclosporine and mycophenolate mofetil in all recipients after operation. According to Daclizumab dosage, these recipients were divided into 1-dose group, 2-dose group and over 2-dose group. All patients received Daclizumab 1 h before operation.Results The patients subject to Daclizumab were followed up from 3 months to 57 months. Seven of them had acute rejection ( 11.3 %) at intervals for 10.3 months, from 2 months to 14 months. Patient who had acute rejection at 10th month after operation lost his graft at 13th month after transplantation for graft dysfunction. The incidence of acute rejection was 15.6 % among 45 patients followed up over 12 months. Conclusions Induction therapy of Daclizumab could decrease the incidence of acure rejection, delay the time of acute rejection and relieve the severity of rejection. More graft can be long-survival. We can lower the dosage of CsA effectively and safely after induction of Daclizumab.

Objective To compare the graft function of 2 methods of kidney harvesting,the modified method of combined liver and kidney procurement and rapid en bloc kidney procurement. Methods The clinical data of 220 cadaveric renal transplantation recipients were collected(12 months follow-up),174 cases from en bloc kidney procurement and 46 from combined liver and kidney procurement.The average harvesting time,the incidence of renal vein injury,1 year kidney survival and incidence of acute rejection were compared between the two methods.Results In average harvesting time and incidence of renal vein injury,the en bloc kidney procurement were better than the method of combined liver and kidney procurement.However,the method of combined liver and kidney procurement was better than the en bloc kidney procurement in 1 year kidney survival,1 year incidence of acute rejection and average warm ischemia time.There was no difference in 1 year survival of patients and 24 h,1 week and 1 year graft function after transplantation. Conclusion Although the method of combined liver and kidney procurement is better than the en bloc kidney procurement in 1 year kidney survival and 1 year incidence of acute rejection,there is no difference between the 2 methods in 1 year survival of patients and graft function after transplantation.

Objective To observe the changes and significance of blood fat and myocardial enzymes in patients with hypothyroid myopathy before and after substitutional treatment.Methods The levels of TC, TG, LDL-C,AST, LDH, HBDH and CKMB were detected in 72 cases with hypothyroid myopathy patients before and after substitutional treatment and 60 healthy controls. Results The levels of TC,TG and LDL-C in hypothyroid myopathy patients before substitutional treatment were significantly higher than those in control group ( all P ＜ 0. 05 ), and then significantly low after treatment,which had no significant difference with control group( all P ＞0. 05). The levels of AST,LDH,HBDH and CKMB in hypothyroid myopathy patients before substitutional treatment were significantly higher than those in control group( all P ＜ 0. 05 ) ,and then significantly low after treatment,which had no significant difference with control group( all P ＞0. 05). Conclusion The levels of blood fat and myocardial enzymes were significantly increased in hypothyroid myopathy patients, and recovery to normal after substitutional treatment.

Objective To assess the significance of urethral sphincter electromyography (US-EMG) and external anal sphincter electromyography (EAS-EMG) for the diagnosis of multiple system atrophy (MSA).Methods US-EMG and EAS-EMG were performed in 9 patients who were diagnosed as MSA.Duration,motor unit action potentials amplitude,polyphasicity,as well as recruited pattern and amplitude during powerful contraction were recorded and analyzed.Results Among 9 patients who were diagnosed as MSA,7 cases showed neural injury by both US-EMG and EAS-EMG.There was significant difference of electromyographic findings between US-EMG group and EAS-EMG group (average volatility (μV):1063.44 ±499.92 vs 634.89 ±265.07; polyphasic wave:0(0,20％ ) vs 57％ (28％,63％ ) ; t =2.567,P=0.033;t =2.833,P=0.012).Conclusions Although US-EMG may be difficult to perform,US-EMG may have the same specificity as EAS-EMG for the diagnosis of MSA,especially for the diagnosis of MSA patients only with urination disorders,who are involved in Onuf neclear according to some of the abnormal indexes.

Objective To find out the risk factors of early pulmonary infections after renal transplantatioa Methods The data were collected from 96 patients receiving renal transplantation between Oct. 2006 and Oct 2010, including 48 cases of early lung infection after renal transplantation as infection group, and 48 patients receiving immunosuppressive regimen at the same period as-control group. Taking the factors of lung infecition as variables, t test or chi-square test was used in univariate analyses whereas logistic regression was used in multivariate analyses. Results Single factor analysis showed that induction therapy, albumin levels, dose of steroid in 1 month after operation,family income and prophylactic SMZ treatment were related to lung infectioa Analysis of multiple variables logistic regression revealed that induction therapy, albumin levels, dose of steroid in 1 month after operation and prophylactic SMZ treatment were related to lung infection. Conclusion The correlation analysis indicated that induction therapy and dose of steroid in 1 month after operation have positive correlations with pulmonary infection, while albumin levels and prophylactic SMZ treatment have negative correlations with pulmonary infection.

Objective To analyze diagnostic evaluation of urethral sphincter electromyography (US-EMGs) for patients with multiple system atrophy (MSA).Methods Totally 15 patients who were diagnosed as MSA were examined as treatment group while 17 non-MSA patients were examined as controls.US-EMGs were performed in the both groups.Spontaneous activities when relax,parameters of motor unit potentials(MUPs) mean duration and amplitude,percentage of polyphasic ware,satellite potential,recruitment potentials and amplitude when strong contraction were recorded and analyzed.Results USEMGs changes of various abnormalities were found in 13 cases (86.7％) in MSA group.There were significant differences of electromyographic findings between the MSA group and control group including MUPs mean duration[(12.79 ±3.18)ms vs (9.49 ± 1.51)ms] and amplitude[(828.53 ±459.89) μV vs (378.76 ± 152.26) μV] as well as recruitment potentials [(11.47 ± 21.55) ％ vs (8.23 ± 10.74) ％] and amplitude [(2.19 ± 1.24) mV vs (0.75 ± 0.42) mV] when strong contraction (all P values ＜ 0.05).Conclusions There is certain value of US-EMGs for the diagnosis of MSA.It could be used as a routine electrophysiological method for the patients who are suspected of MSA.It could be a supplement of externalanal sphincter electromyography.

Objective:To explore the feasibility and influencing factors of E-cervix cervical elasticity analysis technology in analyzing normal cervical function during non pregnancy.Methods:213 women who underwent vaginal ultrasound examination in the Ultrasound Department of Foshan Maternal and Child Health Hospital from May 2019 to November 2019 were selected as the research objects. Taking the median sagittal section of the cervix as the initial section, the E-cervix technology software package was started to automatically obtain the elastic contrast index (ECI), hardness ratio (HR), cervical strain rate (IOS), cervical strain rate (EOS), cervical strain ratio (IOS/EOS) and cervical length (CL). The relationship among age, menstrual cycle, BMI index, birth history, delivery mode and elastic parameters were compared.Results:There was no correlation between the elastic parameters and age, and there was no significant difference among different age groups ( P>0.05); there was no significant difference in the elastic parameters of cervical tissue in menstrual period, proliferative period and secretory period ( P>0.05); there was no significant difference in the elastic parameters of underweight, normal and overweight ( P>0.05); CL was positively correlated with body mass index (BMI) ( r=0.225, P<0.05), there was no correlation between other parameters and BMI ( P>0.05); there was no significant difference between the elastic parameters of patients with and without birth history ( P>0.05); the CL of women with cesarean section [(34.22±4.96)mm] was higher than that of women with natural birth [(29.03±4.14)mm] ( P<0.05), and the other parameters had no statistical significance ( P>0.05). Conclusions:The elastic parameters of cervix obtained by E-cervix technique are not affected by age, BMI, menstrual period, reproductive history and delivery mode, and can be used for quantitative evaluation of cervical function.

BACKGROUND:With the development of industry and agriculture, organotin compounds have been widely used in China. Organotin compounds cause a common occupational poisoning. The toxicity of organotin was reported in animal studies; however the reports about human organotin intoxication are very rare. In this study we retrospectively analyzed the clinical manifestations of 15 organotin-poisoned patients who had been treated at our hospital from 2002 through 2007. METHODS:Fifteen patients with organotin poisoning were admitted to Sir Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine from 2002 to 2007. They were 9 males and 6 females, aged from 25 to 52 years. Clinical manifestations and Glasgow Coma Scales showed that the poisoning was mild in 4 patients, moderate in 6 and severe in 5. The severe patients were given glucocorticoid after hospitalization by intravenous guttae of 500 mg methylprednisolone for the first day, followed by 160 mg methylprednisolone per day for three days, and then 80 mg methylprednisolone per day for another three days. Potassium glutamate and sodium glutamate were intravenously dripped to reduce blood ammonia; intravenous guttae plus oral administration of potassium 9 g/day was used to correct intractable hypokalemia; sodium bicarbonate was used to correct metabolic acidosis, and sedatives were used to control spasm and twitch; mechanical ventilators were used in 4 patients with dyspnea. RESULTS:Most of the patients showed elevated level of blood ammonia, decreased level of blood potassium and metabolic acidosis, but some had demyelination changes shown by CT and MRI. Treatments included correction of metabolic acids, blood potassium and ammonia, and mechanical ventilation when necessary. For patients with injuries of the nervous system, glucocorticoids were given immediately after hospitalization. These patients showed intractable hypokalemia and metabolic acidosis during the treatment. Forteen patients recovered completely without long-term side-effect. One patient in the aphasiac stage restored the linguistic capacity during a 6-month follow-up. CONCLUSIONS:Elevated level of blood ammonia, decresed level of blood potassium, and metabolic acidosis are common in patients with organotin poisoning. Demyelination can be observed in patients with severe poisoning. The abnormalities of the patients are reversible after suitable treatments.

OBJECTIVE:To provide reference for rational use of antibiotics in the clinic. METHODS:From 2012 to 2014,5 medical records were selected randomly from 17 clinical departments each month,1 005 cases in 2012,1 020 cases each year in 2013 and 2014,a total of 3 045 cases. Rationality of antibiotics use was analyzed to summarize and analyze irrational drug use. RE-SULTS:The rate of antibiotics use from 2012 to 2014 were 39.90%,36.27% and 32.84%;the rational rate of antibiotics medical orders were 40.90%,68.11% and 82.67%. Irrational drug use manifested as irrational medication time,unreasonable drug selec-tion,inappropriate indications,inappropriate drug selection,inappropriate usage and dosage,inappropriate drug combination, off-label use etc. CONCLUSIONS:By clinical pharmacistsadvance interventionandadministrative intervention,the use of an-tibiotics in wards of our hospital tend to be more reasonable. But it still necds to strengthen awareness arnd management to effective-ly protect the rational drug use.

Objective To investigate the genetic heterogeneity of 5’-NCR of HCV genotype 1b.Methods We selected 147 HBV genotype 1b serum samples. HCV 5’-NCR fragments were amplified from these samples by use of RT-PCR assay and sequenced after using restriction endonuclease Mbo Ⅰ and BamH Ⅰ. We analyzed the phylogenetic trees of the samples and compared them with 40 isolates of HCV genotype 1b.Results The sequencing reports indicated the isolates of HCV genotype 1b recognized by BamHⅠat position 117 by a substitution (C-T) at position 120 in HCV genotype 1b viruses in China. Of 147 samples, 17 (11.56%) samples for one BamHⅠrecognization position, 26 (17.69%) for neither BamH Ⅰ recognization position nor Mbo Ⅰ,6 samples (4.08%) for two Mbo I recognization position, 18(12.24%)for one MboⅠrecognization position.Conclusions Of 147 HBV genotype 1b serum samples, 54.42% for one Mbo I recognization position, whether this have relationship with the response to IFN therapy provide the framwork for future detailed investigation of HCV antviral therapy. There is specific BamH I recognization position in isolates of HCV genotype 1b in China as compared to the other 40 HCV 1b isolates. The role of this specific mutation needs to be further researched.
