Objective To compare the clinical results of radial head resection with those of open reduction and internal fixation in treatment of Mason type- Ⅲ comminuted fracture of radial head. Methods 58 cases of Mason type- Ⅲ radial head fracture were treated in our department from January, 1983 to July, 2005. 28 cases had resection of the fractured redial head, while the other 30 cases had open reduction and internal fixation. The outcomes were assessed on the basis of pain, motion, strength, radiographic findings, and elbow functional rating score. Results The resection group had a mean follow- up of 5.5 years (2 to 6), while the internal fixation group had 10 years (3 to 13). The average pain VAS (visual analog scale) score was 18.7 (11 to 25) for the resection group and 23.5 (17 to 25) for the fixation group with a P value of 0.0023. The elbow extension averaged - 12.4? in the resection group and - 5.8? in the fixation group (P0.05) , but the decrease of elbow extension and forearm rotation differed statistically between the 2 groups (P

[Objective]To study the clinical results of treatment of local osteochondral fracture lesions on the talus dome associated with ankle fracture using autologous osteochondral transplantation.[Method]There were 18 patients with osteochondral fracture defects of the talus dome associated with ankle fracture, male 10, female 8, with the average age 33.5 years (18~49 years). Transplantation procedure was osteochondral cylinders from non-weight bearing surface of the ipsilateral knee and implant the donor graft into the recipient holes of talus cartilaginous defects with press-fit technique. The outcomes were assessed on the basis of ankle functional rating score, radiographic findings and MRI findings.[Result]The patients were followed up for 17 to 40 months (mean, 28 months). The ankle functional rating score was measured by the Baird and Jackson functional rating score system. The averaged scores was 96.3?3.5,excellent in 14 cases, good in 3 cases and fair in 1 case. The rate of being excellent and good was 94.4%.The rate of posttraumatic arthritis was 5.6% (1/18) and osteochondritis dissecans was 5.6% (1/18).[Conclusion]Autogenous osteochondral transplantation using ipsilateral knee osteochondral grafts is an effective surgical procedure on treating acute local osteochondral fracture lesions of the talus associated with ankle fracture.

The clinical and electrocardiographic data of 35 cases with CAVB were analyzed. They could be divided into two groups: chronic (28 cases) and transcient(7 cases). The primary diseases of the patients in the chronic group were coronary heart disease(CHD) in 11 cases, a condition of unknown cause in 12, and miscellaneous diseases in 5.The clinical and ECG manifestations of the 12 cases with unknown cause were suggestive that the disorder was most likely to be primary degeneration of conduction bundles(PDCB). PDCB differed from CHD by the following:(1) In PDCB, there was neither history of chest pain nor factors vulnerable to CHD being found. No ischemic changes cound be found on the ECG of PDCB cases.(2) The duration of CAVB was longer in PDCB cases (mostly over 3 years) than in CHD cases (all under 2 years).(3) The onset of CAVB occurred at a younger age in PDCB(an average of 50.6 years) than in CHD(an average of 66.3 years).The difference between the two was significant(P

Objective: To observe and analyze the efficacy and safety of naloxone in the treatment of patients with pulmonary encephalopathy. Methods:50 patients with pulmonary encephalopathy were randomly divided into the observation group and the con-trol group. All the patients were carried out continuous oxygen with non-invasive ventilator. The control group was treated with the con-ventional treatment, and the observation group was given naloxone on the basis of conventinal treatment. The treatment course was 7 days. The clinical efficacy, clinical indicators and adverse events of the two groups were observed. Results:The total effective rate of the observation group reached 92. 00%, which was higher than that of the control group without statistical significance (72. 00%, P>0. 05). The levels of pH, PaO2, PaCO2, angiotensinⅡand IL-8 were significantly improved in both groups after the treatment (P<0. 05), and the improvement in the observation group was much better than that in the control group (P<0. 05). The incidence of ad-verse reactions of the two groups after the treatment showed no significant difference (P>0. 05). Conclusion: Early application of naloxone in the treatment of pulmonary encephalopathy can improve the clinical indices significantly with low incidence of adverse reac-tions and high safety, which is worthy of promoted use in clinics.

Objective To investigate instant messenger management on moderate asthma control in young and middle-aged patients.Methods Sixty young and middle-aged asthma patients enrolled were divided into 2 groups by random number table,traditional management group (group A) and messenger management group (group B),and received the asthma treatment with traditional management or messenger management for 1 year.The compliance,control condition,pulmonary function and Saint George respiratory questionnaire(SGRQ) were compared between two groups.Results After one year management,there were 20 patients in proceeding of the standard treatment,15 total control,10 partial control and 5 uncontrolled in group A,while there were 26 patients in proceeding of the standard treatment,21 total control,7 partial control and 2 uncontrolled in group B.Compared with group A,the treatment adherence(x2 =6.331,P ＜ 0.05),satisfaction degree (t =6.051,P ＜ 0.01),asthma control rate (x2 =6.490,P ＜ 0.05),efficacy satisfaction (t =6.051,P ＜ 0.01) were all increased in group B.Forced expiratory volume in 1 second was elevated more significantly in group B than that in group A [(0.132 ± 0.175) L vs.(0.326 ± 0.125) L] (t =5.099,P＜ 0.01).SGRQ scores were decreased more obviously in group B than that in group A (t =4.316,P ＜ 0.01).Conclusions The asthma control,respiratory and pulmonary function can be improved by messenger management in young and middle-aged patients.So promoting the messenger management model actively is advantageous to improve the level of prevention and treatment of asthma in China.

AIM:To investigate the roles of microRNA-134 (miR-134) in the cisplatin resistance of lung ade-nocarcinoma cells.METHODS:miRNA microarray was applied to compare the miRNA expression profile between A549/CDDP and A549 cells.Real-time PCR was used to confirm the expression of miR-134.miR-134 mimics and inhibitors were transfected into A549/CDDP and A549 cells, respectively.MTT assay was used to detect the sensitivity of lung cancer cells to cisplatin.Western blot was applied to test whether miR-134 regulated forkhead box protein M1 ( FOXM1 ) and multi-drug-associated protein 1 ( MRP1 ) expression.RESULTS: Based on the data of miRNA microarray, 13 miRNAs were found to be differentially expressed in A549/CDDP cells compared with A549 cells, among which miR-134 was the most significantly down-regulated one.Compared with control group, A549/CDDP cells transfected with miR-134 mimics showed greatly enhanced sensitivity to cisplatin as indicated by IC50 values (P<0.01).In contrast, suppression of the miR-134 level in the A549 cells resulted in a decreased sensitivity to cisplatin (P<0.01).FOXM1 siRNA down-regulated the pro-tein levels of FOXM1.A549/CDDP cells transfected with si-FOXM1 showed enhanced sensitivity to cisplatin (P<0.01). In addition, the result of Western blot showed that miR-134 repressed MRP1 protein expression.CONCLUSION: miR-134 effectively increases the sensitivity of lung adenocarcinoma cells to cisplatin, and this effect of miR-134 may be partly due to its regulation of FOXM1 and MRP1 expression.

Objective:To explore the feasibility of inguinal subcutaneous immunotherapy for allergic rhinitis ( AR ) in mice. Methods:36 female BALB/c mice were divided randomly into six groups( n=6 per group) including the control A,the model A, the treatment A groups,and the control B,the model B,the treatment B groups(inguinal subcutaneous immunotherapy for group A, cervical back subcutaneous immunotherapy for for group B). AR model was established with ovalbumin. At 25 to 55 days,ovalbumin im-munotherapy were performed in treatment groups,once two days,15 times totally. After intranasal rechallenge was performed at 56 to 62 days the AR symptom scores were documented. The eosinophils(EOS)in the nasal mucosa were measured by chromotropic acid 2R staining. Ovalbumin-specific IgE( OVA-sIgE) in the serum and expression of interferon-γ and interleukin-4 in the nasal lavage were measured by enzyme-linked immunosorbent assay meanwhile the ratio of interferon-γ and interleukin-4 was calc μlated. SPSS17. 0 software was used to analyze the data. Results:Before treatment ,the AR symptom scores of the model and treatment groups were more than 5. After treatment,the treatment A group were less than 5. The EOS count of the control A,model A,treatment A groups and the control B,model B, treatment B groups was 0. 78 ± 0. 31, 21. 60 ± 2. 90, 10. 43 ± 2. 56, 0. 83 ± 0. 46, 22. 44 ± 3. 39, 23. 40 ± 4. 24, respectively. The EOS count of the treatment A group was significantly lower than those in model A group ( P<0. 05 ) . There was no significant difference between treatment B and model B group ( P>0. 05 ) . OVA-sIgE expressed was negative in control groups and positive in other groups. The ratio of interferon-γ and interleukin-4 was 10. 75 ± 3. 38,10. 38 ± 3. 08,3. 02 ± 0. 69,2. 71 ± 0. 89,2. 52 ± 0. 30,5. 45±1. 41,respectively. The ratio in treatment A group was significantly higher than those in model A group(P<0. 05). There was no significant difference between treatment B and model B group ( P>0. 05 ) . Conclusion: Inguinal subcutaneous immunotherapy has a good effect on this disease. It spends short time ,has simple operation and good feasibility,which is a novel treatment method for AR in mice.

The microfluidic channels integrated with microring resonator were designed. The salt coalescence on chip surface caused by liquid volatilization in open environment was avoided and only 30 μL of reaction solution was consumed. These channels significantly reduced the experiment cost. The design, fabrication and characterization of a highly sensitive and label-free silicon-on-insulator (SOI) microring optical resonator integrated with the microfluidic channels were demonstrated. The radius of the microring was 5 μm and the straight waveguide with a width of 450 nm was employed in the microring resonator. The microring resonator device had many advantages such as high sensitivity, label-free and real-time detection. Using different concentrations of ethanol solution with known refractive indices, the refractive index detection sensitivity was 76.09 nm/RIU and the volume refractive index detection limit was 5.25×10Symbolm_4 RIU. We also demonstrated the label-free quantitative specific detections of human immunoglobulin G (IgG) solutions using an antibody-modified microring resonator by measuring the resonance wavelength shift resulting from refraction index changes causing by the immobilization of antibodies and specific recognition between antibodies and antigens, respectively. The results showed that the microring optical resonator could real-time monitor the reaction between biological molecules, the resonator could be used in the quantitative detection and biological sensing.
