Objective To evaluate the clinical effect of potassium permanganate solution in treating the infected prepuce wound. Method From July 2000 to July 2007,97 patients with infected prepuce wound from Beijing Chaoyang hospital and other hospitals, aged 3 ～ 69 years, averaging 22.6 years, were all washed with 0. 1% potassium permanganate solution for 5～10 minutes 1～3 times a day. The 8 cases with abscess were sutured when exudate disappeared and fresh granulation tissue appeared. Results For the 89 infected patients, the wound surface became clear, dry and less exudate appeared after 3～5 days and then formed scabs. They all healed in 1 to 2 weeks. The 8 cases with abscess were all healed within 1 to 2 weeks after saturation. Conclusion Potassium permanganate solution is a convenient, economic and effective method in treating the infected prepuce wound.

Objective To explore the key points of the diagnosis and treatment of severe pneumonia following renal transplantation in the elderly. Methods The clinical data of 28 patients with severe pneumonia following renal transplantation were retrospectively analyzed, including 20 cases aged <60 years (<60 years old group) and 8 cases aged ≥60 years (≥60 years old group). Results In <60 years old group, the severe pneumonia occurred during 1-13 months after the renal transplantation. All the patients had fever. 10 cases coughed and 8 cases had expectoration. 6 cases had type I respiratory failure (RF) and 3 cases experienced type 11 RF. 6 cases had lobar pneumonia and 13 cases occurred interstitial pneumonia. One case experienced lung consolidation. The pathogens of 16 cases in <60 years old group were identified, including 4 cases with bacterial pneumonia, 4 cases with cytomegalovirus (CMV) pneumonia, 2 cases with pneumocystis carinii pneumonia, Ⅰ case with mycoplasma infection, Ⅰ case with tuberculosis infection, and 4 cases with mixed infection (2 cases infected by bacteria plus CMV, 1 case by bacteria plus fungi and 1 case by bacteria plus tuberculosis). Combined drugs (broad-spectrum antibiotic, antivirus and antifungal agent) were administered on the initial stage and sensitive drugs were used later according to the pathogens. Hormone or immunoglobulin was used when other drugs were useless. 17 cases were cured and 3 cases died. In ≥60 years old group, the severe pneumonia occurred during 1-9 months after renal transplantation. All 8 patients had fever, too. 5 cases coughed and 3 cases had expectoration. 3 cases experienced type ⅠRF and 1 case experienced type Ⅱ RF. 3 cases had lobar pneumonia and 5 casesoccurred interstitial pneumonia. The pathogens of 5 eases were identified. Among them, 2 cases were affected by bacterial pneumonia, 1 case by CMV pneumonia and 2 cases by mixed pneumonia (one by bacteria plus CMV, one by bacteria plus fungi). Similar modality was applied, and 5 cases were cured and 3 cases died. Conclusions Most of severe pneumonia occur during 1-9 months after renal transplantation in the elderly. The main pathogens are bacteria and CMV. Medications for all of the most common pathogens and assisted ventilation should be used early. Specific narrow-spectrum antibiotic or antiviral drugs could be used quickly after pathogens were identified, and hormone or immunoglobulin could be administered to patients when the infection is severe or the pathogens are uncertain.

Objective To understand current situation of surgery grading management in 22 hospitals from Beijing Municipal Administration of Hospitals,and to discuss the problems and to make suggestions for better application and management.Methods Based on general survey,Surgery of Grading Conditions of All Municipal Hospitals was issued to 22 municipal hospitals to make related staff fill related data.Results Except for 3 specialty hospitals,19 hospitals have launched the surgery grading management,while they are in different steps of implementing hierarchical directory,surgeon permission and dynamic management.These hospitals have different reference standards of making hierarchical directory.84.2％ hospitals give surgeons authorities according to levels of operations evaluated by professional title,surgery grade and doctors' technical skills.There are 14 hospitals applying information management on surgery grading.Conclusion Uniform criteria of hierarchical directory,extension of surgeon permission system and implementation of surgery grading information management will contribute to regulation fulfillment.

Background Bietti crystalline dystrophy (BCD) is a congenital and autosomal recessive hereditary eye disease characterized by multiple glistening intraretinal crystals scattered over the fundus.Studies determined abnormality of fatty acid metabolism probably is associated with BCD.However,the study on the alteration of blood lipid level in BCD patients is rare.Objective This trail was to study the change of serum lipids in BCD patients.Methods A total of 50 patients with bilateral BCD and 50 matched healthy volunteers were included from November 2011 to March 2013 in Beijing Tongren Eye Center with the approval of Ethic Committee of Beijing Tongren Hospital.Written informed consent was obtained from each subject before any medial examination.Peripheral blood of 3 ml was collected from the subjects.The serum concentrations of triglyceride (TG),total cholesterol (TC),low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were measured and analyzed.The examination outcome was identified based on the criteria of China Adult Dyslipidemia Prevention Guideline (Version 2007).Results Abnormality of serum lipid content was detected in 58.00％ patients (29/50),and hypertriglyceridemia and hypercholesteremia were in 34.48％ (10/29),respectively,and mixed hyperlipidaemia was in 27.59 ％ (8/29).The serum levels of TG,TC and LDL-C were (1.63± 1.19) mmol/L,(5.10±1.05) mmol/L and (3.27±0.97) mmol/L in the BCD group,which were significantly higher than (0.93± 0.33) mmol/L,(4.33 ±0.56) mmol/L,(2.63 ±0.51) mmol/L of the normal group (t =4.036,4.496,4.095,all at P=0.000).Conclusions The serum lipid levels elevate in BCD patients,which might be related to the occurrence of BCD.

Objective:To investigate the effect of controlled low central venous pressure (CLCVP) combined with hepatic blood occlusion on blood loss and hemodynamics in hepatectomy. Methods:Sixty hepatocellular carcinoma patients with American Society of Anesthesiologists (ASA) Ⅰ-Ⅱ undergoing hepatectomy were randomly divided into two groups. One was the group of hepatic blood occlusion (group I);the other was the group of CLCVP combined with hepatic blood occlusion (group II). During the parenchy-mal transection phase of surgery, 60.05). Likewise, no significant difference was noted in MAP and HR at different time points of the two groups (P>0.05). The CVP in groupⅡwas significantly lower than that in groupⅠat the beginning of and 20 min after the paren-chymal transection phase of the surgery. Conclusion:CLCVP combined with hepatic blood occlusion can reduce blood loss effectively during hepatectomy.

Objective To explore the effect of the clinical case oriented management model on nurses comprehensive ability, psychological and critical mind. Methods In 2014 on the implementation ofroutine clinical case management modelas the control group, collected 97 cases of clinical cases. In 2015 on the implementation ofthe clinical case oriented management modelas the observation group, collected 110 cases of clinical cases. Compared two methods of management to improve the nurse management theoretical knowledge, clinical practice ability and deal with the size of the case skills help. When/after clinical special case found the influence for nurses, including psychology, work in the nursing work will, enthusiasm, independent ability to deal with related cases and the nurse critical thinking ability, etc. Results The proportion of the nurses thought that it was helpful to improve the management of theoretical knowledge, clinical practice ability and deal with the size of the case skills and the case analysis of satisfaction were 98.79%(244/247), 99.19%(245/247), 98.79%(244/247), 99.60%(246/247) in the observation group, and 88.57%(217/245), 87.35%(214/245), 87.76%(215/245), 90.61%(222/245) in the control group. The differences were statistically significant (χ2=21.390-27.571, P < 0.01). The proportion of the nurse considered that special case on the psychological effects of nursing work, engaged in the willingness and enthusiasm were the main factor were 15.79%(39/247), 13.77%(34/247), 11.34%(28/247) in the observation group, and 31.84%(78/245), 31.02%(76/245), 30.61%(75/245) in the control group. The differences were statistically significant (χ2=17.475, 21.097, 27.611, P < 0.01). After special case, the percentage of nurses to independently handle the case, help others, loss rates were 97.57%(241/247), 2.02% (5/247), 0.40% (1/247) in the observation group, and 85.71% (210/245), 12.24% (30/245), 2.04% (5/245) in the control group. The proportion of nurses to independently handle the case in the observation group was higher than that in the control group, but the ratio of nurses to help others, loss rates in the observation group were lower than those in the control group, the differences were statistically significant (χ2=22.647, P<0.01).Critical thinking score, the observation group of nurses in the search for truth, open mind, analytical ability, system organization, judging thinking self-confidence, curiosity, cognitive maturity, such as total score were respectively (43.24±4.01), (43.03±4.12), (47.66±4.23), (44.21± 3.92), (44.00 ± 4.97), (52.13 ± 4.44), (48.23 ± 4.85), (319 ± 14.57) points. The control group nurses were respectively (39.00±3.56), (38.90±3.28), (43.65±2.47), (40.55±1.99), (39.00±3.40), (47.87±4.01), (41.89± 5.11), (292.23 ± 6.02) points. The differences were statistically significant(t =12.15-24.19, P < 0.01). Conclusions The clinical case oriented management model can improve nurses comprehensive ability, reduce the adverse impact of the special case for nurses, improve the clinical nurses' critical thinking ability, to ensure patient safety.

BACKGROUND: The renal transplanted recipients were in poor immunosuppressive state. Compared to common person, the bladder transitional carcinoma in recipients was aggressive and easy to recurrence. Looking for a more effective therapy method to decrease the recurrence of recipients' bladder transitional carcinoma is the hot and difficult problem in clinical study.OBJECTIVE: To analyze the efficacy and safety of submucosal injection epirubicin following transurethral resection of bladder tumor (TUR-Bt) to treat the recurrence of bladder transitional cell carcinoma in renal transplantation recipients.METHODS: Totally 9 renal transplantation recipients with transitional cell carcinoma of bladder were retrospectively studied. The patients' periods without cancer, the frequency of recurrence within one year, the rates of side effect, the changes of tumor grading following recurrence and allograff function were recorded when the routine method and submucosal injection epirubicin following TUR-Bt were used in different period respectively.RESULTS AND CONCLUSION: Submucosal injection epirubicin following transurethral resection of bladder tumor was safe and effective to treat bladder transitional cell carcinoma recurrence in renal transplantation recipients. Compared to the routine perfusion, periods without cancer and the frequency of recurrence within 1 year were significantly decreased, which can elevate recipients life quality and long-term survival rates.

Surgical resection remains the only curative option of treatment for hepatocellular carcinoma,but centrally located tumors remain problematic.Extended right or left hepatectomy removes 60％ to 85％ of the hepatic parenchyma and is associated with more hepatic failure.Mesohepatectomy,resection of central hepatic segments (Couinaud's segments Ⅳ,Ⅴ,Ⅷ) and leaving the right and left segments in situ,preserves more functional hepatic tissues than extended hepatectomy.Despite its technical demands,mesohepatectomy should be considered as an alternative treatment for central huge hepatic tumors.

Intrahepatic bile duct stones located at the upper part of the hepatic duct.The percentage of intrahepatic biliary cholesterol calculus is increasing in recent years,and the incidence of this type of bile duct stones is free from infection or obstruction.The formation of intrahepatic bile duct stones might not only related to the micro-environment changes in the biliary tract,but also related to the changes of metabolic function of hepatocytes or cholangiocytes.In this article,the mechanism of biliary hydrodynamics on the formation of intrahepatic bile duct stones was reviewed.

Objective To explore the effect of MICA-Ab expression on the prognosis of sensitized renal transplantation recipients.Methods A total of 51 sensitized recipients (PRA more than 20%) in our hospital from August 2007 to April 2010 were enrolled in the study.In these patients,29 cases received protein A immunoadsorption and detection of MICA-Ab was performed before and after protein A immunoadsorption.Other 22 patients received MICA-Ab detection when they were hospitalized.Associations of PRA,HLA-matches,acute rejection,and serum creatinine of postoperative week 1 and week 4 with MICA-Ab were analyzed retrospectively.Results Sixteen recipients (31.4%) had positive MICA-Ab expression but their acute rejection rate was not higher as compared to the patients with negative MICA-Ab expression.Recipients with PRA＞40% showed higher expression level of MICA-Ab than recipients with PRA≤40% (P≤0.05).HLA-match did not show influence on MICA-Ab expression.MICA-Ab positive group had no higher serum creatinine level than negative group in postoperative week 4.MICA-Ab level decreased significantly after protein A immunoadsorption.Conclusions MICA-Ab expression increases in the sensitive recipients but does not influence the prognosis.Protein Aimmunoadsorption can eliminate MICA-Ab effectively in sensitized recipients.
