Methods Thirty-three township central hospitals in 1 1 counties were randomly select-ed,7 920 outpatient prescriptions,medical records of 465 non-surgery patients and 213 surgery patients were inves-tigated and analyzed. Results Of 33 hospitals,antimicrobial usage rate in outpatients and inpatients was 56.60%and 89.68% respectively,combined antimicrobial usage rate was 24.16% and 43.58% respectively. Antimicrobial use density in inpatients was 147.25DDDs. Antimicrobial usage rate in surgery patients was 97.18% ,combined an-timicrobial usage rate was 59.90% ,the percentage of one drug,two-drug combination and three-drug combination was 40.10% ,47.82% ,and 12.08% respectively. The percentage of antimicrobial use in patients of type Ⅰ,Ⅱ, and Ⅲincision was 97.56% (40/41),96.93% (158/163)and 100.00% (9/9)respectively,combined antimicrobial us-age rate was 30.00% ,67.72% ,and 44.44% respectively.Conclusion The overuse of antimicrobial agents exists in 33 township central hospitals,antimicrobial usage rate,combined usage rate,antimicrobial use density and antimi-crobial prophylaxis in typeⅠincision operations are all high.

[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.

To investigate the clinical improvement of limping gait in patients with ankylotic hips and limb length discrepancy.Methods:From 1996 to 2005,12 patients with ankylotic hips and limb length discrepancy were treated by distraction osteogenesis with a mono-lateral external fixator and an intramedullary nail.The limb length discrepancy was 6.20-12.50 (median 8.45) cm.Limping gait was classified according to the recommendations of the American Academy of Orthopedic Surgeons/Hip Society and scored according to Harris:no limping scored 11 points,mild limping scored 8 points,moderate limping scored 5 points,while severe limping scored 0 points.Limping gait was severe in all patients pre-operatively and the total score was 0.Results:All patients were followed up for 30.00-46.00 (median 38.55) months,and all reported improvement in limping gait.The gain in length was 6.00-12.50 (median 8.20) cm,and the mean residual limb length discrepancy was 0-0.50 (median 0.20) cm.The total treatment time was 41.00-82.00 (median 61.50) weeks,the lengthening time was 14.00-38.00 (median 29.55) weeks.At the last follow-up,10patients had mild limping gait and 2 had moderate limping gait; the total score was 90.00.The median score was 7.50 (P25 was 8.00,P75 was 8.00).According to Wilcoxon signed rank test,the post-operative limping gait scores were significantly higher than pre-operative (P=0.001 ).Conclusion:Femoral lengthening can improve the limping gait significantly in ankylotic hips and limb length discrepancy.

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.

ObjectiveTo investigate the changes of non-linear dynamics characteristics of EEG during picture memory masks, and the application of non-linear dynamic analysis for memory research.MethodsEEGs of 30 healthy old volunteers were recorded under the states of opened eyes and picture memory. Correlation dimension (D2) was calculated for all subjects.ResultsD2 increased significantly during memory tasks compared with the rest state with eyes opened (P<0.05). In different memory tasks, the complexity of mental functions and the regions involved in the memory task were different.ConclusionNon-linear analysis is appropriate for the study of functional changes and working mechanism of brain during memory.
