OBJECTIVERadial corrective osteotomy is an established but challenging treatment for distal radial malunion. There is an ongoing discussion about whether an opening or closing-wedge osteotomy between should employed. The purpose of the present study was to retrospectively compare the clinical and radio graphic results between conventional opening-wedge osteotomy and closing-wedge technique.

METHODSFrom January 2004 and December 2012,42 patients with extra-articular distal radial malunion were managed with corrective osteotomy and were followed for a minimum of one year. Twenty-two patients (5 males and 17 females, ranging in age from 25 to 75 years old) were managed with radial opening-wedge osteotomy and implanting of interpositional bone graft or bone-graft substitute, and twenty patients (4 males and 16 females, ranging in age from 19 to 79 years) were managed with simultaneous radial closing-wedge and ulnar shortening osteotomy without bone graft. The selection of the surgical procedure was determined by the surgeon. Each patient was evaluated on the basis of objective radio graphic measurements, and functional outcomes were determined on the basis of clinical examinations, including range of wrist motion, grip strength, pain-rating score, Mayo wrist score, and Disabilities of the Arm, Shoulder and Hand (DASH) score.

RESULTSThe mean duration of follow-up was 36 months (ranged, 12 to 101 months) for the opening-wedge cohort and 28 months (ranged, 12 to 87 months) for the closing-wedge cohort. The two techniques were comparable in terms of complications. Post-operative volar tilt and ulnar variance were improved significantly in each cohort. The ulnar variance was more frequently restored to within defined criteria (22.5 to 0.5 mm) in the closing-wedge cohort than that in the opening-wedge cohort. The post-operative mean extension-flexion are of the wrist and Mayo wrist score were significantly better in the closing-wedge cohort. Differences in the pronation-supination arc, grip strength, pain-rating score, and DASH scores between these two cohorts were not significant.

CONCLUSIONThe closing wedge osteotomy technique is an effective reconstructive procedure for the treatment of extra-articular distal radial malunion. It is significantly better than the opening-wedge osteotomy technique in terms of the restoration of ulnar variance, the extension-flexion arc of wrist motion, and the Mayo wrist score.

Objectives To investigate the changes of erythropoietin(EPO)expression in rats after focal cerebral ischemia/reperfusion injury.Methods Male Sprague-Dawley rats were randomly divided into normal,sham,cerebral ischemic/reperfusion(CIR)groups.Middle cerebral artery occlusion(MACO)model was established by Longa's method,and reperfusion was followed 2 hours after occlusion in CIR group.The rats' brain neurological deficit scores were evaluated at 24 h,48 h,72 h and 96 h after reperfusion.The protein expression of EPO was determined by immunohistochemistry staining and Western blotting in each time points.Results The rats' brain neurological deficit scores at 48 h,72 h and 96 h were significantly increased(3.40±0.32,3.60±0.17,3.70±0.21,all P<0.05)compared with those at 24 h(3.00±0.22)after reperfusion in CIR group.The results of immunohistochemistry staining and Western blotting showed that the positive expression of EPO proteins in rats started at 24 h(0.36±0.05,140.20±0.30)after cerebral ischemic/reperfusion injury,increased significantly at 48 h(1.09±0.10,145.40±0.16),reached the peak at 72 h(1.29±0.09,156.23±0.12),began to decline at 96 h(0.98±0.04,141.56±0.36).Conclusions Cerebral ischemia and reperfusion injury can induce increased expression of EPO protein,which suggests that EPO may have protective effect on nerve cells under the condition of ischemia and reperfusion.

OBJECTIVETo observe the impact of inducing the formation of the post-moxibustion sore on the efficacy of bronchial asthma treated with scarring moxibustion.

METHODSThree hundred and seventy-two cases diag nosed definitely as bronchial asthma at remission stage were randomly divided into a modified nursing group (248 cases) and a conventional nursing group (124 cases). The scarring moxibustion was applied at Dazhui (GV 14), Feishu (BL 13), Danzhong (CV 17) and Tiantu (CV 22) in either group. The direct moxibustion with moxa cone was adopted. In modified nursing group, 0.5% Iodine was used for the sterilization at moxa abscess. The herbal plaster was cut into an inverted triangle and compressed on the wound. After suppuration, the fester was not cleaned in each dressing change. Additionally, the patients were advised to have high-protein diets after moxibus tion till abscess dropped. In conventional nursing group, 0.5% Iodine was used for the sterilization at moxa abscess. The herbal plaster was cut into a round shape that could cover completely the moxa wound. After suppuration, in each dressing change, the wound was cleaned and sterilized. Additionally, the patients were advised to avoid any stimulating food after moxibustion till abscess dropped. The clinical efficacy, the change of C3 content in blood serum and the clinical symptom score were observed in two groups.

RESULTSThe total effective rate was 93.5% (232/248) in modified nursing group, which was better than 79.0% (98/124) in conventional nursing group (P < 0.01). C3 content increased apparently after treatment as compared with that before treatment in either group (both P < 0.01), but C3 level increased much more apparently in modified nursing group as compared with that in conventional nursing group (P < 0.01). The clinical symptom score reduced apparently after treatment in either group (both P < 0.01), but that reduced much more apparently in modified nursing group as compared with that in conventional nursing group (P < 0.01).

CONCLUSIONIn the treatment of bronchial asthma with scarring moxibustion, to induce the formation of the post-moxibustion sore achieves the better clinical efficacy as compared with conventional nursing.

OBJECTIVETo observe the clinical significance of nitric oxide (NO) and 8-isoprostane (8-isoPG) changes in exhaled breath condensate ( EBC) of acute respiratory distress syndrome (ARDS) patients after treated by Qingfei Decoction (QD).

METHODSTotally 48 ARDS patients receiving mechanical ventilation were equally assigned to the QD treatment group and the control group by random digit table. EBC specimens were collected by modified Ecoscreen breath condensate collector (German JAEGER Company) on the first day and the fifth day after confirmed diagnosis of ARDS. Concentrations of NO and 8-isoPG in EBC were measured by ELISA. The oxygenation index and APACHE II scores were recorded at the same time.

RESULTS(1) The fatality rate in the QD treatment group was lower than that in the control group (8.3% vs 37.5%, P < 0.05). (2) After treatment NO and 8-isoPG concentrations in EBC were lower in the QD treatment group (34.49 ± 5.67 µmol/L, 30.09 ± 7.89 ng/L) than in the control group (39.78 ± 9.27 µmol/L, 35.65 ± 8.90 ng/L; P < 0.05). (3) After treatment improved oxygenation index value was higher in the QD treatment group than in the control group (120.88 ± 35.16 vs 101.50 ± 37.70, P < 0.05). After treatment APACHEII scores was lower in the QD treatment group than in the control group (6.21 ± 3.51 vs 10. 26 ± 4.33, P < 0.05).

CONCLUSIONTreatment of ARDS patients by QD was favorable in controlling inflammation, alleviating lung injury, and improving clinical efficacy.

Objective To observe the brain activation of interictal epiletiform discharges(IEDs) and to localize the epileptogenic foci of epilepsy.Methods The electroencephalogram(EEG)and functional MRI data of 12 focal epileptic patients were acquired using a combination of EEG and functional MRI simultaneously.The IEDs onset time detected with EEG were set as the time parameters in an event- related paradigm of functional MRI analysis.The spatial and temporal characters of IEDs activation were analyzed in detail.In order to confirm the consistency of this method,all patients were scanned repeatedly and the results were correlated with clinical evaluation.Results Of the 12 patients,valid data from EEG- fMRI were obtained from 10 patients in a total of 18 sessions..Compared with the structural foci,the epileptic foci localization results of eleven sessions were good,five sessions were fairly good,and two sessions were poor.The results obtained from six patients in two separate sessions were concordant.respectively.Moreover,thalamic activation was detected in ten sessions,cerebellar activation was detected in all sessions,and the deactivation was found in the default mode loci in nine sessions. Conclusion The method of performing EEG and fMRI simultaneously can potentially be a useful tool in epilepsy research.

OBJECTIVETo explore the association of occupational injuries, with their individual safety perception and safety behaviors in steel workers, so as to provide basis for preventing and controlling occupational injuries.

METHODSCase-control design was used to compare the difference in safety perception and safety behaviors between the injury group and the control, and also to compare the difference in safety behaviors between different safety perception groups.

RESULTSThere were remarkable differences in attitude toward the safety degree of the work (chi(2) = 5.444, P < 0.05), and accidents happening (chi(2) = 4.552, P < 0.05) between case group and control group. There were remarkable difference in safety behaviors including manual operations instead of facilities (chi(2) = 10.015, P < 0.01), cleaning up, examining or adjusting machine during work (chi(2) = 7.351, P < 0.05), attention diversion (chi(2) = 10.937, P < 0.01) and unsafe wearing (chi(2) = 7.521, P < 0.05) between case group and control group. There were also significant differences in many safety behaviors between those who thought the job was safe or unsafe.

CONCLUSIONThere is some association of occupational injuries with safety perception and safety behaviors. To reduce the occurrence of occupational injury, measures should been focused on strengthening safety management and controlling unsafe behaviors.

OBJECTIVETo investigate the effect of curcumin (Cur) on radiosensitivity of nasopharyngeal carcinoma cell CNE-2 and its mechanism.

METHODThe effect of curcumin on radiosensitivity was determined by the clone formation assay. The cell survival curve was fitted by Graph prism 6. 0. The changes in cell cycle were analyzed by flow cytometry (FCM). The differential expression of long non-coding RNA was detected by gene chip technology. Part of differentially expressed genes was verified by Real-time PCR.

RESULTAfter 10 micro mol L-1 Cur had worked for 24 h, its sensitization enhancement ratio was 1. 03, indicating that low concentration of curcumin could increase the radiosensitivity of nasopharyngeal carcinoma cells; FCM displayed a significant increase of G2 phase cells and significant decrease of S phase cells in the Cur combined radiation group. In the Cur group, the GUCY2GP, H2BFXP, LINC00623 IncRNA were significantly up-regulated and ZRANB2-AS2 LOC100506835, FLJ36000 IncRNA were significantly down-regulated.

CONCLUSIONCur has radiosensitizing effect on human nasopharyngeal carcinoma CNE-2 cells. Its mechanism may be related to the changes in the cell cycle distribution and the expression of long non-coding IncRNA.
