Objective To establish a risk assessment model for laparoscopic partial nephrectomy (LPN) with segmental renal artery clamping (SRAC).Methods In the first stage,107 patients who underwent LPN with SRAC from December 2009 to September 2011 were retrospectively reviewed.There were 63 men and 44 women,aged from 11-80 years,mean (58.1 ±10.1) years.The blocking program of target arteries was dependent on the experience of the surgeon and CTA.After multiple Logistic regression analysis,variables used to build a nomogram were selected using a backward elimination scheme.Then,a model for a clamping program customized to the patient was designed.In the second stage,the surgical outcomes of 141 patients who subsequently underwent LPN-SRAC with the applied model from October 2011 to June 2014 were compared with those of the first stage patients.There were 84 men and 57 women,aged from 51-75years,mean (59.9 ± 8.6) years.Outcomes of two stages were compared.Results Five potential predictors were initially assessed including segmental renal artery angle,target artery diameter,and distance to the abdominal aorta,renal hilum,and kidney midline.The regression equation was then set up with Logistic regression analysis.Compared with the patients in the first stage,success rate of clamping in the second stage,with the help of the new SRAC model,was improved from 74.8% (175/234) to 94.2%(227/241) (P < 0.001),the total operative time was decreased from (88.6 ± 10.9) min to (80.2 ±16.6) min (P<O.001),and operative blood loss was reduced from (198.7 ±111.6) ml to (168.5 ±117.8) ml (P =0.042).No obvious differences were observed in warm ischemia time,postoperative hospitalization,R.E.N.A.L nephrometry score,or number of final clamped branches.Conclusion The model for assuring clamping success was helpful in designing an SRAC program.

OBJECTIVETo observe the effect of Ginkgo Leaves Tablet (GLT) on memory quotient (MQ) of mild cognitive impairment (MCI) patients.
METHODSOne hundred and thirteen patients were randomly assigned to the control group (55 cases) and the treatment group (58 cases). Patients in the control group received dietetic therapy and physical exercises, while those in the treatment group additionally took GLT, 19.2 mg each time, three times daily. The treatment course was 12 months for all. The MQ of all the patients was assessed by WMS-RC before treatment,at 6-month of treatment, and 12-month of treatment.
RESULTSCompared with the control group, the improvement of MQ increased in the treatment group 0.5 and 1 year after treatment (P < 0.05). The clinical efficiency of MQ obviously increased in the treatment group (48.28% and 50.00%), showing statistical difference when compared with the control group (30.91% and 27.27%, P < 0.05, P < 0.01). There was statistical difference in added scores of recognition, regeneration, understanding, and recitation test at 6-month of treatment and 12-month of treatment between the treatment group and the control group (P < 0.05, P < 0.01).
CONCLUSIONGLT was effective in improving MQ of MCI patients, especially in improving recognition, regeneration, understanding, and recitation test.

OBJECTIVEThe aim of this study was to investigate the clinicopathological characteristics, effective treatment and prognosis in childhood and adolescent Hodgkin's lymphoma.
METHODSA total of 88 patients with childhood and adolescent Hodgkin's lymphoma were treated in the Cancer Hospital of CAMS from 1998 to 2005. The clinicopathological and follow-up data of the patients were retrospectively reviewed. The survival rate was calculated by Kaplan-Meier method and compared by log-rank test. COX multivariate prognosis analysis was performed.
RESULTSThe 2-year event-free survival rate of the 88 patients was 86.4%, the 5-year event-free survival rate was 61.4%, and the 5-year overall survival rate was 95.5%. Univariate analysis showed that the stage of disease (P = 0.033), "B" symptoms (P = 0.028), bulky disease (P = 0.007), splenomegaly (P = 0.050), LDH elevation (P = 0.020), chemotherapy regimen (P = 0.003) were prognostic factors in the 5-year event-free survival rate. Splenomegaly (P = 0.039), LDH elevation (P = 0.033), chemotherapy regimen (P = 0.008) were prognostic factors of 5-year overall survival rate. Multivariate analysis showed that chemotherapy regimen (P = 0.033), stage of disease (P = 0.023), LDH elevation (P = 0.008), "B" symptoms (P = 0.044), bulky disease (P = 0.009) were independent prognostic factors of 5-year event-free survival rate. The chemotherapy regimen (P = 0.012) and LDH elevation (P = 0.046) were independent prognostic factors of 5-year overall survival rate.
CONCLUSIONSThe non-ABVD chemotherapy regimen, stage IV disease, LDH elevation, associated with "B" symptoms and bulky disease are independent prognostic factors of 5-year event-free survival rate. LDH elevation and non-ABVD chemotherapy regimen are independent prognostic factors of 5-year overall survival rate.

AIMTo study the therapeutic efficiency of amphotericin B liposome (AmB-L) targeting to the brain in mice with meningitis.
METHODSAmphotericin B liposome targeting to the brain were prepared by film-sonication method. Their concentration and encapsulation percentage were determined. The Candida albicans was injected into the brain of BALB/c mice and the meningitis model was set up. Then the therapeutic efficiency of amphotericin B liposome targeting to the brain was studied.
RESULTSThe encapsulation percentage of amphotericin B liposome was 93.3%. The meningitis model was set up after the Candida albicans was injected into the brain of BALB/c mice for 2 h. The therapeutic efficiency was increased after conjugating RMP-7 (the commercial nama is Cereport) to the surface of amphotericin B liposome.
CONCLUSIONThe therapeutic efficiency of Amphotericin B liposome targeting to the brain in the mice with meningitis was better than that of the common amphotericin B liposome and the life of the mice in AmB-L-PEG-RMP-7 group was longer than that of the mice in AmB-L-PEG group and AmB-L-PEG + RMP-7 group.

OBJECTIVE:
To explore the value of transthoracic echocardiography (TTE) in transcatheter closure of atrial septal aneurysm (ASA) combined with secoundum-type atrial septal defect (ASD).
METHODS:
Fourteen patients (3 males and 11 females) who had ASA combined with secoundum-type ASD were diagnosed by TTE or transesophageal echocardiography. The ASA projected to the right atrium in all patients. The width of basilar part was 13 approximately 24 (18.5+/-3.9) mm, and the vertical extent was 7 approximately 11(9.7+/-1.8) mm. Ten patients combined with single hole ASD and 4 patients with multiple hole ASD. Blood shifting from the left atrium to the right atrium was displayed in color Doppler in all patients. All patients were treated by transcatheter closure under the guiding of X fluoroscopy and TTE, and examined with TTE during the follow-up.
RESULTS:
Transcatheter closure was successfully performed by 14 occluders in all patients. No residual shunt was detected immediately by TTE after the procedure in all patients. During the 6 approximately 12 month follow-up, no residual shunt or occluder shifting was found, the dimensions of the heart became normal in 11 patients (79%) and were significantly decreased in 4.
CONCLUSION
Transcatheter closure is feasible in patients with ASA combined with secoundum-type ASD, and extra attention must be paid to the specialty. TTE is very important in case selection before transcatheter closure, and it may be used to monitor and guide the procedure during transcatheter closure.

BACKGROUNDSince an effective method for generating induced pluripotent stem cells (iPSCs) from human neural stem cells (hNSCs) can offer us a promising tool for studying brain diseases, here we reported direct reprogramming of adult hNSCs into iPSCs by retroviral transduction of four defined factors.
METHODSNSCs were successfully isolated and cultured from the hippocampus tissue of epilepsy patients. When combined with four factors (OCT3/4, SOX2, KLF4, and c-MYC), iPSCs colonies were successfully obtained.
RESULTSMorphological characterization and specific genetic expression confirmed that these hNSCs-derived iPSCs showed embryonic stem cells-like properties, which include the ability to differentiate into all three germ layers both in vitro and in vivo.
CONCLUSIONOur method would be useful for generating human iPSCs from NSCs and provide an important tool for studying neurological diseases.

OBJECTIVETo investigate the involvement of E-cadherin-catenin adhesion system in Bowen's disease (BD) and cutaneous squamous cell carcinoma (SCC).
METHODSFifteen normal skin, 28 BD and 18 SCC specimens were stained with monoclonal antibodies against E-cadherin and beta-catenin. Evaluation of the staining results was performed with semi-quantification of the pattern and intensity of staining, percentage of positive cells, and cytoplasmic staining.
RESULTNormal skins strongly expressed membranous E-cadherin and beta-catenin, but their expression was remarkably reduced in BD and SCC. Abnormal staining of beta-catenin was observed in the cytoplasm or cell nuclei of BD and SCC.
CONCLUSIONAbnormal expression of the E-cadherin/catenin complex is common in SCC and BD.

OBJECTIVETo analyze the clinical features of interstitial pneumonitis (IP) associated with interferon therapy for chronic hepatitis C.
METHODSWe report the first case of IP in China resulting from pegylated interferon alpha-2a in combination with ribavirin for treatment of hepatitis C viral infection. A statistical analysis of the related literatures documenting such IP cases was performed using SPSS 11.5 software.
RESULTSOf the 22 patients reported to develop IP after interferon therapy alone or in combination with ribavirin, 83%, 72% and 56% of the patients had the symptoms of dyspnoea, dry cough and fever, respectively. Twenty of these cases presented with restrictive pulmonary functional impairment and/or hypoxemia, and diffuse infiltration on chest radiography and/or CT. Complications were documented in 71% of the cases within 12 weeks of the treatment. The majority (85%) of the patients had favorable prognoses with an average recovery time of 7.5 weeks. Compared with the patients with mild and moderate pulmonary function impairment, 8 patients with severe pulmonary functional impairment had early onset of IP during the interferon therapy (6.6 vs 14.1 weeks, P<0.05), and a higher rate of corticosteroid treatment (75% vs 54%, P>0.05).
CONCLUSIONIP is a rare pulmonary complication associated with IFN therapy, and patients with chronic hepatitis C should be followed up closely in the first 12 weeks of interferon therapy. Prompt discontinuation of medication is mandatory in the presence of IP, and corticosteroid therapy may not be essential for patients with mild or moderate pulmonary functional impairment under close monitoring. The severity of pulmonary damage is associated with the time of complication occurrence, and corticosteroids are required when obvious pulmonary toxicity occurs in early stage of the treatment (within 6 weeks) to reduce the pulmonary damage.

PURPOSETraumatic diaphragmatic rupture (TDR) needs early diagnosis and operation. However, the early diagnosis is usually difficult, especially in the patients without diaphragmatic hernia. The objective of this study was to explore the early diagnosis and treatment of TDR.
METHODSData of 256 patients with TDR treated in our department between 1994 and 2013 were analyzed retrospectively regarding to the diagnostic methods, percentage of preoperative judgment, incidence of diaphragmatic hernia, surgical procedures and outcome, etc. Two groups were set up according to the mechanism of injury (blunt or penetrating).
RESULTSOf 256 patients with a mean age of 32.4 years (9-84), 218 were male. The average ISS was 26.9 (13-66); and shock rate was 62.9%. There were 104 blunt injuries and 152 penetrating injuries. Preoperatively diagnostic rate was 90.4% in blunt injuries and 80.3% in penetrating, respectively, P < 0.05. The incidence of diaphragmatic hernia was 94.2% in blunt and 15.1% in penetrating respectively, P < 0.005. Thoracotomy was performed in 62 cases, laparotomy in 153, thoracotomy plus laparotomy in 29, and combined thoraco-laparotomy in 12. Overall mortality rate was 12.5% with the average ISS of 41.8; and it was 21.2% in blunt injuries and 6.6% in penetrating, respectively, P < 0.005. The main causes of death were hemorrhage and sepsis.
CONCLUSIONSDiagnosis of blunt TDR can be easily obtained by radiograph or helical CT scan signs of diaphragmatic hernia. For penetrating TDR without hernia, "offside sign" is helpful as initial assessment. CT scan with coronal/sagittal reconstruction is an accurate technique for diagnosis. All TDR require operation. Penetrating injury has a relatively better prognosis.
