Objective To investigate the CT and MRI findings of facial neuroma to promote diagnostic accuracy. Methods Nine facial neuromas consisted of 8 schwannoma and 1 neurofibroma. High resolution CT were performed on 7 cases, routinal CT scan on 2 patients. Six cases were examined by MRI, in which 5 cases were used constrast media. Results Five tumors on right side and 4 on left were detected. The tumor affected the internal auditory canal segment of facial nerve in 1 case, labyrinth segment in 4, anterior genu in 6, tympanum segment in 7, mastoid segment in 6,horizontal segment in 5 and parotid segment in 3. CT demonstrated enlargement of the facial nerve canal, benign bone remodeling in the location of geniculate ganglion and stripe soft issue along the course of facial nerve. MRI found that involved facial nerve became thickened markedly as a stripe or soft mass by several segments, that were isointense to brain on T 1WI and isointense or hyperintense on T 2WI and enhanced obviously. Conclusion The segmental soft tissue mass along the facial nerve course is the characteristic of facial neuroma. Gadolinium enhanced MRI is an effective method for detecting the lesion.

Objective To explore the effective prognostic factors of patients with multiple traumas. Method During January 2003 to March 2007, totally 324 patients with multiple traumas were treated in the emergency department of Renmin Hospital, Wuhan University. The relationship between prognosis and age, visiting time after injury, injury severity score (ISS) ,main wounded part and shock degree was analyzed. The data were tested using ehi-square test and logistic regression method. Results Seventy-eight patients died and 246 patients survived, the total mortality was 24.1%. Statistical differences existed in mortalities of patients with different visiting time (visiting hospital within 1 h,16.7%; visiting hospital beyond 1h, 37.4%),ISS (16≤ISS≤24, 5.7%; 25≤ISS≤40, 19.2%; IS8>40, 41.3%) and shock degree (non-shock, 11.8%; mild shock, 13.6%; moderate shock,27.7%; severe shock,46.9% ) ( P<0.01). There were no significant difference in mortalities among patients with different age (<18, 23.8% ; 18～38, 21.7% ; 38～58, 24.2% ;>58, 32.5% ) and with various main wounded part (head, 26.0%; neck, 25.3%; chest, 27.3%; abdomen, 24.1%; limbs, spine and pelvis,16.3%), P>0.05. Logistic regression study showed that mortality increased with postponed visiting time after injury, augment of ISS and aggravation of shock degree, with the exception that there was no differenoe in mortality of patients with between non-shock and mild shock. Conclusions Visiting time after injury, ISS and shock degree were valuable progrostic predictors for multiple traumas. It's vital to follow principle of damage controlled surgery and emphasis on the timeliness and integrity of medical rescue and control shock actively to reduce mortality of patients with multiple injuries.

Objective To evaluate the safety and efficacy of endoscopic techniques for diagnosis and treatment of breast diseases. Methods Related literatures of recent years were reviewed. Results A minimally invasive endoscopic technique can be performed through small incisions. This can contribute greatly to reducing postoperative pain, shortening recovery time, and achieving a good cosmetic outcome. Under endoscopy, meticulous dissection and hemostasis can be achieved. Endoscope assisted subcutaneous mastectomy, immediate mammary reconstruction, sentinel lymph node biopsy and axillary lymph node dissection, for breast cancer can be performed safely. Endoscopic surgery can also be applied for the diagnosis and treatment of benign breast tumor and transaxillary removal of glandular tissue in gynecomastia. In addition, fiberoptic ductoscopy can be used to diagnose patients with nipple discharge. Endoscopic surgery for patients with breast diseases can offer an excellent cosmetic outcome and maintain normal physiologic functions without a noticeable scar. It helps to give the patients confidence and improve the quality of life. Conclusion Breast surgery is a good candidate for endoscopic techniques.

Enhancer of rudimentary homolog (ERH) is a small, highly conserved protein among eukaryotes. Since its discovery nearly 20 years ago, its molecular function has remained enigmatic. It has been implicated to play a role in transcriptional regulation and in cell cycle. We recently showed that ERH binds to the Sm complex and is required for the mRNA splicing of the mitotic motor protein CENP-E. Furthermore, cancer cells driven by mutations in the KRAS oncogene are particularly sensitive to RNAi-mediated suppression of ERH function, and ERH expression is inversely correlated with survival in colorectal cancer patients whose tumors harbor KRAS mutation. These recent findings indicate that ERH plays an important role in cell cycle through its mRNA splicing activity and is critically required for genomic stability and cancer cell survival.

Objective　A recent study has shown the association between a sulfonylurea receptor gene-1 (SUR1) variant and hyperinsulinemia in normal individuals from a high diabetes risk ethnic group,supporting the hypothesis that the primary insulin hypersecretion may be an antecedent of type 2 diabetes.Methods　To test this hypothesis in Chinese population,we studied the allele and genotype distribution of the polymorphism at -3 position of intron 24 in SUR1 by PCR-RFLP technique in 206 unrelated normal glucose tolerant subjects with strong family history of type 2 diabetes (group A) and 110 normal individuals without family history of diabetes (group B).Results　The frequency of “-3c” allele and “-3cc” genotype of intron 24 in group A was significantly higher than that in group B (64% vs 54%，P=0.004 and 38% vs 24%，P=0.002 respectively).Moreover,in group A, those carrying “cc” genetype had a higher BMI (27.27±6.37 vs 24.99±3.43kg/m2，P＜0.05；27.27±6.37 vs 25.28±2.78kg/m2，P＜0.05),fasting insulin (15.52±10.72 vs 9.27±5.03U/ml,P＜0.01；15.52±10.72 vs 10.79±7.80U/ml,P＜0.05) and 2h insulin levels (76.41±54.02 vs 55.43±49.60U/ml,P＜0.01；76.41±54.02 vs 55.71±40.39, P＜0.05) as well as lower insulin sensitivity ［HOMA(Ri］: 4.00±3.09 vs 2.79±1.32, P＜0.01； 4.00±3.09 vs 2.82±2.94, P＜0.01) as compared with that in carriers of other genotypes (“ct” and “tt”).Conclusion　This study suggested the possibility that the defect in SUR1 gene might contribute to the insulin hypersecretion which might be the cause of subsequent increased body weight and decreased insulin sensitivity.

Objective: To construct a lentiviral vector (LV) of RNA interference (RNAi) targeting HBs gene and to observe its effect on the replication of HBV and expression of antigens. Methods: The effective sequence of siRNA targeting HBs gene was confirmed in our previous study. The complementary DNA containing both sense and antisense Oligo DNA of the targeting sequence was designed, synthesized and cloned into the lentivirus vector (pGCLM-GFP). The resulting lentivirus vector containing HBs shRNA was named LVshHBs, and it was confirmed by PCR and sequencing. 293T cells were cotransfected with lentivirus vector pGCLM-GFP, pHelper 1.0 and pHelper 2.0. All virus stocks were produced by calcium phosphate-mediated transfection. The titer of virus was tested according to the expression level of GFP. HepG2. 2.15 cells were infected with LVshHBs and the supernatant of the cells was subjected to ELISA, Western blotting analysis and HBV DNA quantitative analysis. Results: PCR and DNA sequencing demonstrated that the LVshHBs-producing HBs shRNA was successfully constructed. The titer of concentrated virus was 5 × 108-2 × 109 TU/ml. The inhibitory effect was efficient and the corresponding viral transcript and expression of antigens were decreased after infection. The inhibitory effect was observed 4 days after infection and peaked 9 days after the initial treatment with RNAi. Secreted HBsAg was reduced by > 70% in cell culture compared with the negative control, which is also confirmed by Western blotting and real time PCR. After quantification of HBV DNA, the level of DNA relative to the controls was also significantly reduced after RNAi treatment(P<0.05). Conclusion: The lentivirus RNAi vector of HBs has been successfully constructed. The lentiviral microRNA-based RNAi targeting HBs can specifically mediate the down regulation of HBs expression, inhibiting HBV replication and antigen expression.
