OBJECTIVE:To investigate the perioperative use of antibacterials in patients undergoing C-sect.METHODS:The medical records of 753 cases between Oct.2005 and Mar.2007 were reviewed retrospectively.RESULTS:All the patients(100.00%)undergoing C-sect received antibacterials by iv gtt during perioperative period,and 99.07% were given at 0.5h before operation.Among all the antibacterials,73.31% were benzylpenicillin sodium.86.85% of the patients had a course of treatment of 2～3 days;93.36% of the antibacterials were used in single kind.As for the preventive medication outcome,the effective rate totaled 99.20%(694 CR+ 53 PR).CONCLUSION:The perioperative use of antibacterials in patients undergoing C-sect was rational on the whole.The antibacteirals were more often used singly for a course of 2 to 3 days.The low grade kind with low toxicity and cheap price is the preferred preventive medication for patients undergoing C-sect.

OBJECTIVE To find the efficient anti-infection strategy.METHODS The incidence,pathogenic microorganism,prophylaxis,treatments of infectious complications in 30 patients who accepted hematopoietic stem cell transplantation in our hospital were analyzed retrospectively.The results were analyzed statistically compared with reference.RESULTS Incidence of infectious complications was 70.0%.One patient(3.3%) died of hepatic failure and sepsis.CONCLUSIONS There is high incidence of infection in the early stage after hematopoietic stem cell transplantation.It is related with the decrease and recovery time of WBC.Fluconazole has better clinical effects on prevention of fungal infection.Early strong antibacterial therapy can reduce the incidence of severe infection and death rate.

Objective:To understand whether or not biofeedback therapy(BT)and cue- exposure therapy(CET)could decrease craving and heroin-related cue reactivity in abstinent heroin dependents.Methods:Adopting stratified sampling means,60 abstinent heroin dependents whose craving increased after cue exposed,were allocated to experiment group(n=36)and control group(n=24).The control group dependents received assistance and education.Beside the assistance and education,the experiment group also received 12 times combination therapies of BT and CET.Results:After therapies,the experiment group dependents' craving,EMG and skin conductance(SC)were all decreased compared with control group before cue exposures and after cue exposures[Before cue exposures,the indexes were:craving(3.06±7.26)mm vs.(22.32±20.26)mm;EMG(8.52±4.23)μV vs.(12.06±5.17)μV,SC(2.14±1.43)μS vs.(4.61±2.24)μS.After cue exposures the indexes were:craving(6.97±10.30)mm vs.(33.14±25.40)mm,MEG(8.72±4.31)μV vs.(14.79±5.86)μV,SC(2.15±1.33)μS vs.(4.49±2.59)μS;Ps≤0.01.Conclusion:The combination of biofeedback therapy and cue-exposure therapy could decrease the dependents' craving and cue reactivity sensitivity.

Objective To investigate the clinical indicators which could be used to differentiate incarcerated stones from unincarcerated stones by comparing clinical characteristics of patients.Methods 96 patients who were diagnosed as ureteral stones treated by ureteroscopic lithotripsy (URSL) from June 2017 to November 2017 were selected in the study.Clinical characteristics of patients were collected.The total study consisted of 62 male and 34 female patients.The patients' age ranged from 24 to 78 years old and average age was (54.5 ± 12.7) years old.There were 35 patients were diagnosed as ureteral stones with hypertension,9 patients with diabetes,85 patients with hydronephrosis,respectively.The number of patients,whose stone located in upper ureters,middle ureters and lower ureters were 49,19,28,respectively.The average of maximum stone diameter,maximum cross-sectional area of the stone,stone volume,hounsfield units of stone and maximum ureteral wall thickness (UWTmax) at the stone site were (7.75 ± 2.68) mm,(36.12 ± 24.43) mm2,(304.06 ± 303.39) mm3,(755.75 ± 318.05) HU,and (3.18 ± 1.13) mm,respectively.Percussion tenderness over kidney region were positive in 11 cases,weak positive in 64 cases and negative in 21 cases,respectively.Stone-free rate after operation were 93.8％.Patients were divided into two groups,incarcerated or unincarcerated,and statistical differences between clinical characteristics of the two groups were analyzed by univariate analysis.The differences were further compared by multivariate logistic regression analysis to find independent predictors of impacted stones.The ROC curve was used to find the optimal UWT for diagnosis of impacted stone.The accuracy of this value was evaluated and patients were grouped by this value to compare the differences between groups.Results The operation and follow-up were successfully performed in all patients.Univariate analysis showed there were no statistical significance differences in gender [(24 males and 16 females)vs.(38 males and 18 females)],age [(53.4 ± 12.3) years vs.(48.7 ± 12.7) years],previous history of diabetes (4 cases vs.5 cases) and stone location [(19 upper stones,9 middle stones,12 lower stones) vs.(30 upper stones,10 middle stones,16 lower stones)],between the two groups (P ＞ 0.05).Among the clinical characteristics of patients in incarcerated and unincarcerated groups,UWTmax were (4.15 ± 0.94) mm and (2.58 ± 0.76) mm,previous history of hypertension were 20 cases and 15 cases,ipsilateral URSL history were 14 cases and 10 cases,hounsfield units of stone were (847.66 ± 282.39) HU and (698.65 ± 325.50) HU,hydronephrosis were 40 cases and 50 cases,maximum stone diameter were (8.67 ± 2.28)mm and (7.17 ± 2.75)mm,maximum cross-sectional area of the stone were (43.83 ± 23.65) mm2 and (31.14 ± 23.64) mm2,stone volume were (386.20 ± 296.60) mm3 and (253.04 ± 296.29) mm3,percussion tenderness over kidney region were positive in 8 cases(20.0％),weak positive in 27 cases,negative in 5 cases and positive in 3 cases,weak positive in 37 cases,negative in 16 cases,respectively.The difference was statistically significant (P ＜ 0.05).Multivariate logistic regression analysis showed UWTmax (OR =10.40,P ＜ 0.001) at the stone site was significantly correlated with impacted ureteral stones and it was an independent predictor of impacted stones.ROC curve analysis showed that the optimal cut-off value of UWTmax was 3.26 mm.The sensitivity of the value to predict impacted stone is 82.5％ and the specificity is 87.5％.Depending on the cut off value of 3.26 mm,cases were divided into two groups,40 cases were in high UWTmax (≥3.26 mm)group and 56 cases were in low UWTmax (＜ 3.26 mm)group.Higher UWTmax was accompanied with a higher incidence of ureteral edema[77.5％ (31/40) vs.32.1％ (18/56)],polyps [30.0％ (12/40) vs.7.1％ (4/56)],strictures[37.5％ (15/40)vs.12.5％ (7/56)] and a lower stone-free rate[87.5％ (35/40) vs.98.2％ (55/56)].The difference was statistically significant (P ＜ 0.05).Conclusions UWTmax can be used to differentiate impacted stones from unimpacted stones before surgery.The patients with Higher UWTmax (≥3.26 mm) was accompanied with a higher incidence of stone impacted,ureteral edema,polyps,and strictures,and a lower rate of stone clearance.
