[Objective]To introduce a new technique of ankle arthrodesis with trephine by lateral approach and evaluate its clinical effects.[Method]Ankle arthrodesis with trephine was performed in 20 patients with serious lesions.Lateral incision was adopted and osteotomy of fibula facilitated the exposure of the fusion site.A trephine of appropriate diameter was used for bi-osteotomy,thus inside the trephine gaining two bone blocks were then rotated 90? and replanted in situ.The pruned fibula was fixed with screws as on-lay!grafting.Proper cast was utilized postoperatively to maintain a functional position.[Result]The average follow-up period was 26 months(ranged from 6 months to 4 years).All the wounds healed well at 2 weeks and the callus appeared 4 weeks postoperatively.Sufficient pain relief was obtained in all patients at 12 weeks and appearance improved greatly.A solid union was achieved in all cases through the radiograph.[Conclusion]The use of trephine in ankle fusion by lateral approach is proved to be a simple technique with high union rate.The main advantages of the technique over other methods of arthrodesis include: excellent exposure by regular incision;less disturbance of the original joint,thereby preserving normal height of the joint and length of the extremity;no need for extra graft through in-situ grafting of the bone blocks and rigid on-lay grafting of lateral malleolus for high primary stability.

Radiotherapy is the primary treatment for nasopharyngeal carcinoma, and the disease control rate and survival time are able to be greatly improved by enhancing the radiosensitivity. Via mechanisms such as binding to target genes mRNA 3'untranslated region (3'UTR), microRNA (miRNA) inhibits translation, which therefore regulates transcription of target genes and thus affect target protein expression. Recent research showed that miRNAs play significant roles in improvement of radiosensitivity in nasopharyngeal carcinoma. This article reviews mechanism of miRNA action to strengthen radiosensitivity of nasopharyngeal carcinoma and the future of clinical practice of miRNA in this disease.

Objective To compare efficacy of two intensive therapies:continuous subcutaneous insulin infusion(CSⅡ) and multiple subcutaneous insulin infusion (MSⅡ) for treatment of type 2 diabetes mellitus.Methods 60 patients with type 2 diabetes mellitus were randomly divided into 2 groups. Patients in CSⅡ group were treated by insulin (Novolin R) through a infusion pump. Patients in MSⅡ group were treated by Novolin R before meals (3 times a day) and Novolin N at bedtime. Blood glucose was monitored the whole day before and after treatment. Time required for blood glucose to reach the standard level, insulin dosage and hypoglycemia incidence were compared between the 2 groups before and after treatment. Results Both of the 2 therapeutic methods effectively controlled blood glucose (P<0.05). However, the 2 groups had significant difference in terms of the time required for blood glucose to reach the standard level ( 3.6 ± 1.2 d vs. 9.4 ± 3.2 d, P < 0. 01 ), daily insulin consumption (35.2 ± 8.5 u vs. 43.2 ± 10. 1 u, P <0. 01 ) and hypoglycemia incidence (2. 1% vs.9.7%, P <0.01 ). Conclusions CSⅡ and MSⅡ are effective for treatment of type 2 diabetes mellitus. CSⅡ is superior to MSⅡ due to its advantages of quick response, safety, and less insulin consumption.

Background:Gastric cancer(GC)is the fourth commonly seen cancer in the world. The role of Notch signaling pathway in the pathogenesis of tumors has become a focus in related studies,however,the underlying mechanism of Notch1 in GC has not yet been fully understood. Aims:To investigate the expression and significance of Notch1 in human GC tissue. Methods:A total of 115 patients with GC admitted at Jiaxing First Hospital from October 2011 to July 2014 were enrolled. Expression of Notch1 in cancerous tissue and para-cancer noncancerous tissue was determined by immunohistochemistry. The correlation between expression of Notch1 and clinicopathological characteristics of GC was analyzed. Results:Expression rate of Notch1 in cancerous tissue was significantly higher than that in para-cancer noncancerous tissue(73. 9% vs. 3. 5% ,P < 0. 001). Notch1 expression in cancerous tissue was significantly correlated with depth of vascular involvement,lymph node metastasis and TNM stage of GC(P < 0. 05). Conclusions:Notch1 as a cancer-promoting gene is involved in the pathogenesis of GC,and has a close association with tumor invasion and metastasis.

AIM To investigate the preventive effects of taurine on the left ventricle hypertrophy in renovascular hypertensive rats. METHODS Two-kidney 1-clip (2K1C) rats were used to establish the model of renovascular hypertension. The myocardial local aldosterone(Ald) and AngⅡconcentration (MDC,MAC) were measured by radioimmunoassay. Expression of oncogene c-fos mRNA was analyzed by means of in situ hybridization. The myocardial collagen concentration (MCC) was measured by biochemical method. The myocardial tissue structure was observed under the microscope ,and the myocardial fiber diamension (MFD) was measured with micrometer. The linear correlation between MCC, MFD and MAC or MDC was analysed respectively. RESULTS Compared with sham operated rats ,the MCC, MAC, MDC and MFD were significantly increased in 2K1C rats ( P

Background and purpose:Metformin is known to be an insulin sensitization agent and is a fi rst line treatment for patients with type 2 diabetes. Recent clinical studies have revealed that metformin treatment has been associated with reduced cancer risk,which indicated that metformin may be a potential anti-neoplastic agent. We investigated the effects of antidiabetic drug metformin on proliferation and apoptosis in human lung adenocarcinoma cell line A549 in vitro and explored the possible underlying mechanisms. Methods:A549 cells were treated with 0.5 mmol/L,2 mmol/L and 8 mmol/L metformin for 48 hrs. Growth inhibition rates of the cells were measured by MTT assay. Cell apoptosis were detected by ? ow cytometery(FCM). Expressions of three genes including p53,Bcl-2 and Bax mRNA in the cells were measured by Real-Time PCR. Results:The proliferation of A549 cells was inhibited by metformin in a dose-dependent manner. The Inhibition rates of metformin at dosage of 0.5 mmol/L,2 mmol/L and 8 mmol/L group were (29?5)%,(68?3)% and (84.1?2.6)%,respectively. Apoptosis was induced when the cells were treated with moderate to high concentrations of metformin.The percentage of cells in early and late stage of apoptosis was increased from (1.1?0.3)% and (1.78?0.22)% in controlled group to (2.1?0.5)% and (9?4)% in metformin 8 mmol/ L group,respectively. The expressions of p53,Bcl-2 and Bax mRNA were all up-regulated after metformin treatment while the Bcl-2/Bax ratio was signifi cantly decreased. Conclusion:Metformin can inhibit the proliferation of human adenocarcinoma cancer cell line A549 and induce cell apoptosis with moderate to high drug concentrations in vitro,which may partly be attributed to the up-regulation of p53 and down-regulation of the Bcl-2/Bax ratio.

Objective To study the significance of c-met mRNA in axillary drainage after operations for breast cancer. Methods RT-PCR assay was used to examine c-met mRNA in axillary drainage after operations in 52 cases of breast cancer. The relationships between the expression of c-met and the tumor size, metastatic lymph nodes, the expressions of estrogen receptor (ER), progesterone receptor (PR) and c-erbB-2 were analyzed, respectively. In addition, the effect of douching operative field with 5-FU and distilled water on the expression of c-met mRNA was also analyzed. Results ①The proto-oncogene c-met mRNA could be detected in axillary drainage after operations for breast cancer by RT-PCR, and its positive rate was higher than that in routine pathological detection for micrometastasis in the axillary lymph nodes (P
