Objective To evaluate the efficacy and safety of self-management anticoagulation treatment for low pulmonary embolism severity index (PESI) outpatient with acute pulmonary embolism (APE).Methods Sixty-eight patients with APE of PESI grade Ⅰ-Ⅱ were divide into inpatient group and outpatient group with 34 cases each by random digits table.All the patients were treated with low molecular heparin followed by oral anticoagulation,and self-management was used in outpatient group.The efficacy was observed within 14 days and 3 months.The efficacy outcome included recurrent venous thromboembolism (VTE),standardization time of international normalized ratio (INR),VTE-related emergency department visit times,bleeding events and total mortality.Results There were 2 cases(5.9％,2/34) in inpatient group and 1 case (2.9％,1/34) in outpatient group with recurrent VTE,and there was no statistical significance between two groups (P ＞ 0.05).Standardization time of INR in inpatient group [(8.5 ± 2.9) d] was shorter than that in outpatient group [(16.1 ± 4.4) d],and there was significant difference (P＜ 0.01).There was no significant difference in the VTE-related emergency department visit times between two groups (P ＞ 0.05).There was 1 case with major bleeding and 1 death respectively in outpatient group.Conclusion It is effective and safe to give early self-management anticoagulation treatment to APE patients with PESI grade Ⅰ-Ⅱ,which could shorten time spending in hospital and release burden both physically and mentally.

Objective To investigate the cognitive behavioral characteristic longitudinally of the patients after subcortical infarction engaged in feature and binding working memory tasks.Methods The behavioral performances were recorded from 28 patients after subcortical infarction at the 1 st week (W1),3 rd moth (M3) and 6th month (M6) while performing color,location,and color-location binding delayed match-to-sample working memory task.25 healthy volunteers(controls) were investigated once using the same task protocol during the study period.Computer recorded the behavior reaction time and accuracy.Single factor variant analysis of repeated measurement was adopted.Results The accuracy of three memory tasks of M3 ((64.92 ± 5.47) ％ ; (92.88 ± 2.98) ％ ;(82.35 ±7.44)％) was improved than that of W1 ((61.06 ±7.78)％; (90.59 ±2.95)％; (77.06 ±5.58) ％) and the difference had statistically significant (P ＜ 0.05).But the reaction time of M3 ((868.31 ±118.91)ms; (833.37 ± 120.99) ms; (918.72 ± 101.28) ms) was shortened than that of W1 ((914.02 ±110.53) ms; (859.89 ± 139.94) ms; (1150.17 ± 92.02) ms) and the difference also had statistically significant (P ＜ 0.05).In the location-memory task,the correct rate of M6 ((93.91 ± 2.86) ％) was improved than that of M3 ((92.88 ± 2.98) ％) and the reaction time of M6 ((813.24 ± 119.54) ms) was shortened than M3 ((833.37 ±120.99) ms).M6 and M3 to be compared in the color memory task,the correct rate ((64.50 ± 4.49) ％ ; (64.92 ± 5.47) ％) and the reaction time ((866.47 ± 123.87) ms; (868.31 ± 118.91) ms) had no significant difference (P ＜ 0.05).But in the color-location binding task,the correct rate of M6 ((78.49 ± 7.85) ％) and M3 ((82.35 ± 7.44)％) to be compared had significant decreased nearly the level ((77.06 ± 5.58)％) of the stroke beginning.All behavioral performances of patients were worse than that of control subjects except the compare result of location-memory task in M6((93.91 ± 2.86) ％ ; (813.24 ± 119.54) ms).Conclusion Feature memory and binding memory had been damaged in different degrees in the patient after subcortical infarction.The binding memory had the secondary damage what might be related to the secondary nerve fiber degeneration after infarction.

Objective To study the clinical and pathological features of a case of retroperitoneal desmoplastic small round cell tumor. Methods One case of desmoplastic small round cell tumor was presented with review of the literature. Results A 11 years old child complained of abdominal pain and a 9.0 cm?6.0 cm?3.0 cm cystic tumor located in the left retroperitoneal space near the left kindey was resected.The connective tissue was significantly proliferated around the tumor cell nests. Immunohistochemical staining revealed CD 99 (+) and EWS/WT1 (+). After resection of the tumor,chemotherapy was performed with DDP?ifosfamide and VP16. No tumor recorrence has been noted 16 months after operation. Conclusions Desmoplastic small round cell tumor has specific clinicopathologic stigmata occuring usually in young males and the tumor was characterized by expression of MIC2 gene product CD 99 and the EWS/WT1 protein. Surgical resection with cheomotherapy is the treatment of choice.

The dynamica changes of the activity of serum tumor necrosis factor(TNF)was determined in 24 patients with severe burns,and the changes of cardiac and hepatic enzymes,plasma lactate and glucose,serum protein,WBC count etc were determined as well.It was found that TNF was produced in large amounts to damage and degenerate the vascular endothe-lium.Consequently intravascular emboli were more liable to occur to result in tissue hypoxia.TNF could also induce the release of polymorphonuclear neutrophils(PMNs)from the bone marrow.PMNs by chemotacsis accumulated in the inflammatory tissues to produce large amounts of toxic products,which could damage the cells and tissues directly to result in multiple organ failure.Furthermore,TNF,through the mediation of pyrogen and cachectin,could induce febrile reaction,exhaustion of glycogen reserve,and increment of muscular protein catabolism.Eventually the energy consumption of the host would be incresed and his defensive function weakened.

Objective Use the automatic microbiological analysis system which for the streptococci (ATB rapid 32 Strep) to identify streptococci, and compare the examination speed and accuracy with the internationally recognized bacterium identification golden method API 20 Strep (streptococci identification biochemistry system) to enable the clinical microorganism room use ATB rapid 32 Strep identification system correctly, and provide the etiology basis to clinical promptly.Methods Isolate the bacterium from patient blood, cerebrospinal fluid, pig heart, pork and so on, then separate the streptococci in form to the blood plate, lay them in carbon dioxide incubator, after 35 ℃ 24 hours. Use ATB rapid 32 Strep,API 20 Strep and the traditional manual method to identify 18 strains of bacterias and carry on the medicine sensitive experiment.Results ATB rapid 32 Strep identified 16 strains as streptococcus suis II, 2 strains as streptococcus bovis II; API 20 Strep identified 17 strains as streptococcus suis II, 1 strain can not be identified; the tradition manually method identified all of the 18 strains as streptococcus group D . These 18 strains all sensitive to the Chloramphenicol , clindamycin, erythromycin, levofloxacin, penicillin, quinupristin/dalfopristin, cefotaxime, vancomycin and sulfafurazole , and resistant to the tetracyclin.Conclusion ATB rapid 32 Strep can identify the streptococcus suis in 4 hours , and the coincidence rate with API 20 Strep is 94.4%.So ATB rapid 32 Strep is one kind of system which could identify bacterium simply,quickly,accurately,and provide infectious disease etiology information for clinical immediately, satisfy the requirement of clinician and the microorganism examines.

Objective To explore the role of NG2 proteoglycan in the pathogenesis of glomerulosclerosis. Methods Eukaryotic expression vectors carrying the small hairpin RNA (shRNA) for NG2 mRNA , named as Psilencer-NG2, was constructed. Then, rat mesangial cells (RMC) were transfeeted with Psilencer-NG2, Psilencer-NC (negative control), pcDNA/NG2 (NG2 over-expressive vector) and empty vector pcDNA 1 respectively. The expression of endogenous NG2 in RMCs was examined by real-time PCR and Western blotting. Cell proliferation was analyzed by MTT assay and flow cytometry. The expression of laminin was detected by real-time PCR. Results Transfection of pcDNA/NG2 into HBZY-1 cells resulted in over-expression of NG2 mRNA and protein (P<0.05, P<0.05). Transfection of Psilencer-NG2 led to reduced expression of NG2 mRNA and protein (P<0.01, P<0.01). The expression of laminin β1 significantly increased due to overexpression of NG2 and decreased by treating with NG2 siRNA. According to MTT assay, overexpreasion of NG2 significantly stimulated the proliferation of mesangial cells while NG2 silencing inhibited it. NG2 increased the cell number in S phase and decreased the cell number in G0/G1 phase, while silencing NG2 induced the decrease of cell number in S phase and the increase of cell number in G0/G1 phase. Conclusion NG2 actively participates in the pathogenesis of glomerulosclerosis by stimulating proliferation of RMCs and increasing the deposition of ECM.

OBJECTIVETo discuss the applicatioen of flap for the urethroplasty in the distal penile segment in the staged correction of severe hypospadias.

METHODSFrom Oct. 2004 to Aug. 2014, 25 cases with severe hypospadias were treated by staged urethroplasty for urethra reconstruction. The urethral meatus were located at peroscrotum in 4 patinets, at scrotum in 8 patients and at perineum in 13 cases. At the first stage, the urethral plate was divided and chordee was corrected. Then tubularized transverse island flap was used to prefabricate partial distal urethra. The defective urethra was repaired by using the Thiersch-Duplay principle at the second stage.

RESULTSAll patients completed both stages of the operation. The follow-up duration was 6-72 months (average, 24 months). In the first-stage, the modified tabularized transverse preputial island flap was performed on 10 patients, whereas the modified preputial double-faced island flap was performed on the other 15 patients. All of the prefabricated partial distal urethras had no evidence of stenosis or scarring. The result of the second-stage procedure was a complete penis with integrated urethral. All patients were satisfied with cosmetic and functional results. Neither stricture nor diverticula was observed. A good urinary stream during the urination was achieved in 19(19/ 25, 76%) patients. Five cases (5/25, 25%) developed urethrocutaneous fistula and one cases developed meatal stenosis (1/25, 4%) after the second stage repair.

CONCLUSIONSStaged urethroplasty using flap is a good choice for severe hypospadias. The successful rate is relatively high with good cosmetic and functional results.
