Objective To discuss the clinical significance of nephroscopic surgery for simple renal cysts. Methods A 2~4 cm incision was made below the 12th costal interspace. Through the incision the nephroscopic decortication was performed in 26 patients with simple renal cyst. Results The operation time was 20~80 min (mean, 30 min) and the postoperative hospital stay, 3~)6 days (mean, 4 days). No blood transfusion was required and no severe complications were noted. Follow-up observations for 3~)12 months (mean, 8 months) in the 26 patients found no recurrence. Conclusions Mini-incision nephroscopic decortication for renal cysts is feasible and mini-invasive, with advantages of simplicity of performance and quick postoperative recovery.

Objective To explore the early diagnosis and treatment of bronchopulmonary dysplasia (BPD) in premature. Methods Observing and analyzing the onset ,diagnosis of BPD and the outcome treated by dexamethasone in 12 cases that were hospitalized in NICU during the period from January 1994 to January 1999.The follow up study was done for 6 to 12 months after their discharge. Results All of these 12 infants treated by dexamethasone were cured and discharged. The time period of hospitalization was 31 to 67(50?14) days. The one year follow up study after discharge showed that the prognosis of 11 patients were good, only 1 infant suffered from repeated respiratory tract infection. Conclusion Careful observation on clinical manifestations and lab work should be done to those premature babies who suffered from BPD easily for early diagnosis. The early application of dexamethasone in infants with BPD showed perfect results.

Objective To investigate the main predisposing factors of hematoma enlargement in spontaneous intracerebral hemorrhage,reduce the early mortality,and improve clinical outcomes.Methods By a retrospective study of 268 patients,all patients underwent their first computed tomography (CT)scan within 24 hours of arrival and a second CT scan within 72 hours of admission.These predisposing factors were analyzed by means of univariate and multivariate logistic regression analyses.Results The patients occurred early hematoma enlargement were accounted for 27.99% (75/268).Univariate analyses indicated that hematoma shape,midline shift,breaking into the ventricle,thrombin clotting time (TT),white blood cells,neutrophil percentage,serum creatinine,fasting plasma glucose (FPG),and Glasgow coma scale (GCS) were significantly different between the patients with or without hematoma enlargement (P <0.05).Furthermore,multivariate logistic regression analyses revealed that the following four factors were independently associated with hematoma enlargement:the midline shift [OR (95% CI) =3.356 (1.251-8.999),P =0.000],the GCS score [OR (95 % CI) =0.745 (0.671-0.827),P =0.023],the FPG [OR (95% CI) =3.022 (1.232-7.408),P =0.016],and the breaking into the ventricles [OR (95% CI) =2.851(1.158-7.019),P =0.005].Conclusions The midline shift of brain CT scan,the GCS score,the FPG,and the breaking into the ventricles maybe the independent predisposing factors of hematoma enlargement.Therefore,timely review of CT scan and dynamic monitoring of peripheral blood biochemical indicators should be very important for further therapy.

Objective: To study the quality standards for Shenyanghongyao Tablets. Methods: Radix Angelicae Dahuricae was identified by TLC and Ginsenoside R g1 in Radix Notoginseng was determined by TLCS. Results: The linear relationship was at the range of 0.92?g~4.60?g. The average recovery was 97.16%. Conclusion: The methods are available with a good reproducibility and can control the quality of this preparation effectively.

Objective To investigate the electrocardiographic(ECG) characteristics and assess the safety of radiofrequency catheter ablation (RFCA) of ventricular tachyeardia (VT), and frequent ventricular premature con- tractious(VPCs) originating from left ventricular outflow tract(LVOT). Methods Twelve-lead ECG analysis and RFCA were performed in 9 patient with VT or VPCs originating from LVOT. Results The sites to be successfully ablated were in left valsalva sinus in 6 patients,and subaortic valve in 3 patient. ECG revealed tall R wave in leads Ⅱ, Ⅲ ,aVF, V5 and V6. QS morphology in both leads aVR and aVL,QS morphology in lead Ⅰ in most cases. R wave in lead Ⅰ was relative tall, the R/S wave amplitude in lead V1 was over 0.62 ,and precordia R wave transition was irregular. All 9 patients were successfully ablated. No death or recurrenced case during follow-up. Conclusion Ventricular taehycardia and frequent ventricular premature rcontractions originating from left ventricutar outflow tract could be known by some specific ECG characteristics and could be radically treated safely by RFCA.

Objective: To verify the hypothesis that cells with characteristics similar to bone marrow mesenchymal stem cells(MSCs) can be isolated and cultured from human fetal articular cartilage. Methods: Human fetal articular cartilages were harvested from fetuses aborted between 12 and 20 weeks. Cells were grown in monolayer cultures in IMDM medium containing antibiotics, L-glutamine and fetal calf serum. Cells were induced to differentiate into adipocytes, osteoblasts, chondrocytes, and neurons. At various time points, parental and passaged cells were subjected to FACS analysis to determine cell phenotype. Results: We successfully isolated and cultured MSCs from human fetal articular cartilage. These cells had the same morphology, phenotype, and ability to differentiate in vitro as MSCs of bone marrow origin. Conclusion: This study shows that cells with characteristics of MSCs can be isolated and cultured from human fetal articular cartilage.

Objective To explore the differential diagnostic significance of clone analysis for multicentric occurrence (MO) and intrahepatic metastasis (IM) in hepatocellular carcinomas (HCCs).Methods Loss of heterozygosity (LOH) and microsatellite instability (MSI) were analyzed by microsatellite polymorphism test and the integration sites of HBV were assessed by Southern blot in each nodule of the HCCs. The clonalities were then compared between each nodule of the same patient and the diagnosis of MO or IM was concluded. Finally, the results based on clonality analysis were compared with those according to clinicopathological and imaging data. Results According to the results of LOH and MSI in 79 nodules and nontumorous tissue from 35 cases of mutiple HCCs, 5 (14.3%)and 29 cases (82.9 %) were divided into MO and IM, respectively. Both MO and IM presented simultaneously in 1 patient (2.9%). The integration sites of HBV could be analyzed in 77 nodules from 34 multiple HCCs. Among them, 6 (17. 6%) and 27 cases (79.4%) were divided into MO and IM, respectively. Both MO and IM presented simultaneously in 1 patient (2.9%). The classification results of microsatellite polymorphism test and HBV integration sites analysis demonstrated a significant positive correlation (rs = 0.909, P<0.001). Nevertheless, neither the classification of microsatellite polymorphism test nor that of HBV integrate sites analysis was correlated with the discrimination according to clinicopathologic and imaging data (rs=0. 133, P=0. 468, rs =0. 262, P=0. 155, respectively). Recurrence in patients in the MO group occurred significantly later than that in IM cases who were diagnosed by clonality analyses (P=0. 001). Conclusion The clonality analysis based on the results of LOH and MSI or assessments of HBV integrate sites is useful for the differential diagnosis of MO and IM and their treatment and prognosis.

Objective To explore the influence of injury severity on transplantation of embryonic neural stem cells (NSCs) after traumatic brain injury (TBI).Methods The NSCs were isolated from the hippocampus of fetal rats aged at from 12-14 days.The cells were cultured and proliferated in the serum-free medium and identified in vitro.The animals received transplants in the bilateral hippocampal areas at day 3 following mild or moderate TBI separately.Conventional histology,TUNEL and immunohistology were examined to detect BrdU,NSE,GFAP,GalC,NGF and BDNF at day 14 post-implantation.Results BrdU-labeled positive cells in the bilateral hippocampus in the mild TBI group were more than those in the moderate TBI group at day 14 post-implantation.Significant differentiation of the astrocytes recognized as GFAP positive cells in the bilateral hippocampus was found at day 14 post-implantation.The expression of NGF and BDNF proteins was increased following TBI,the most evident in the mild TBI group.Conclusion The influence of injury severity on transplantation may be associated with the change of the microenvironment after TBI.
