[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:Intervertebral disc can bear load but lack vessels. Nucleus pulposus cel s have the problem of phenotype loss during in vitro culture that can lead to degenerative changes. The mechanism of intervertebral disc degeneration remains unclear.
OBJECTIVE:To explore the approaches of isolation, adherence culture, amplification and identification of the rabbit nucleus pulposus cel s in vitro, to observe the growth characteristics of nucleus pulposus cel s in different generations.
METHODS:Type Ⅱ col agenase digestion method plus explants culture method was used to isolate and purify nucleus pulposus cel s and then amplify in vitro. The morphology and growth of primary and passaged cel s was observed under the inverted microscope, the number of cel s was counted and the growth curve was draw. The morphology of the cel s was observed under light microscope after hematoxylin-eosin staining, and the expressions of col agen type Ⅱ and aggrecan were examined by immunocytochemistry.
RESULTS AND CONCLUSION:Nucleus pulposus cel s of rabbit were isolated, cultured and amplified in vitro successful y. Growth activity was observed, and found that the 1-3 generation nucleus pulposus cel s proliferated more rapidly and vigorously. The proliferation of nucleus pulposus cel s was decreased while the cel passaged more generations. These isolated and cultured nucleus pulposus cel s could positively express the col agen type Ⅱ and aggrecan. In vitro combination of type Ⅱ col agenase digestion method and explants culture method could obtain high purity nucleus pulposus cel s, and the cultured nucleus pulposus cel s were grew in round or polygonal. The 1-3 generation of cel s had strong activity.

Objective To investigate hepatitis B virus (HBV) mother-to-child transmission rate in hepatitis B virus surface antigen (HBsAg)-positive pregnant women.MethodsA total of 1355 HBsAg-positive pregnant women and their 1360 newborns (included 5 twins)were collected prospectively.All newborns received hepatitis B immunoglobulin (HBIG) 200 U intramuscularly within 6 hours of birth as early as possible,and were administered with routine 10 μg recombinant hepatitis B vaccine (at 0,1,6 months of birth).The venous blood HBV markers and HBV DNA levels were detected in all newborns at 0,7,12 months of age.The measurement data were analyzed by t test.Qualitative data were analyzed by chi square test,rank sum test or Fisher exact test.Results The intrauterine HBV infection rate of 1360 infants were 1.54％ (21/1360) during 12 months of follow-up.The rate of intrauterine infection in HBeAg positive mothers was significant higher than that of HBeAg negative mothers (4.44％ vs 0,χ2 =35.99; P＜0.05); the rate of intrauterine infection in HBV DNA positive mothers was significant higher than that of HBV DNA negativemothers (3.13％ vs 0,χ2 =21.84; P＜0.05).When maternal serum HBV DNA≥1 × 107 IU/mL,the rate of intrauterine infection was 6.01 ％,which was significantly higher than that of maternal serum HBV DNA＜ 1 × 107 IU/mL (χ2 =39.43,P＜0.05).ConclusionsAfter strict combined active-passive immunization,the rate of HBV intrauterine infection is 1.54％.When mothers are HBeAg positive or with high level of HBV DNA,the rate of HBV intrauterine infection increases significantly.Intrauterine infection is the main cause of failure in immunoblockade of HBV mother-to-child transmission.
