OBJECTIVETo investigate a manipulating therapy for treatment of anterior shoulder dislocation in elderly.

METHODSFrom October 2011 to June 2012,27 elderly patients with anterior shoulder dislocation were treated by extorsion traction and pushing manipulation with fingers, including 7 males and 20 females aged from 65 to 86 years old with an average of 77. The course of disease ranged from 1 h to 1 d. The shoulder manifested square deformity, Dugus signs showed positive, and X-ray displayed anterior shoulder dislocation. Dugus fixation was applied for and removed external fixation at 3 weeks after operation and carried out shoulder functional exercise. Functional evaluation standard on shoulder joint injuries was used for evaluate clinical outcomes.

RESULTSAll patients were gained reduction for the first time, and followed up at 3 months after operation, no dislocation occurred. According to functional evaluation standard on shoulder joint injuries, 22 cases got an excellent result,2 cases good,and 1 case moderate.

CONCLUSIONExtorsion traction and pushing manipulating therapy for treatment of anterior shoulder dislocation in elderly, which has advantages of simple, convenient, less painful, and can avoid iatrogenic injury, is feasible to widespread.

Objective To study interleukin-1 receptor(IL-1R) and connexin(Cx36) gene expression following Mg 2+-free-induced seizures in cultured developing neuron. Methods Rat embryo cortical neurons cultured for 6 and 17 days were exposed to Mg 2+-free media to induce seizure. At different time after Mg 2+-free treatment, real-time RT-PCR was used to detect IL-1R and Cx36 mRNA expression. Results 1. IL-1R mRNA expression transiently decreased after Mg 2+-free treatment in neurons cultured for 6 and 17 days in vitro. Then the levels of IL-1R mRNA expression recovered in neurons cultured for 6 days, but IL-1R mRNA expression were increased in neurons cultured for 17 days compared with control group and the peak was at 24 hours. 2. In neurons cultured for 6 days in vitro, Cx36 mRNA expression increased after Mg 2+-free treatment compared with control group, the peak was at 24 hours. But in neurons cultured for 17 days in vitro, Cx36 mRNA expression decreased at 6 hours after Mg 2+-free treatment compared with control group, the peak was at 24 hours. Conclusions IL-1R mRNA and Cx36 mRNA expression following Mg 2+-free-induced seizures are different between the neurons cultured for 6 and 17 days in vitro. This is possibly related to the different neuron injury between 6 and 17 days in vitro following seizures.

Results Four potential biomarkers were determined which contributed to occurrence, development and recovery of ethanol-induced liver injury in rat, and Yin Chen Hao Tang could significantly recover trajectory change in disorder. Conclusion The developed method was successfully applied to investigate ethanol-induced liver injury in rat, and also hepatoprotective effect of Yin Chen Hao Tang was elucidated.

OBJECTIVETo compare the efficacy and safety of segmental pulmonary vein isolation (SPVI) and circumferential pulmonary vein isolation (CPVI) guided by EnSite NavX system in patients with atrial fibrillation (AF).

METHODSEighty-five patients with paroxysmal AF and persistent AF were enrolled in this study. Forty patients (30 with paroxysmal AF and 10 with persistent AF) underwent SPVI procedure, and 45 (31 with paroxysmal AF and 14 with persistent AF) underwent CPVA guided by EnSite NavX three-dimensional electrophysiological mapping system. All the patients were followed up for over six months.

RESULTSThe success rate was 65% in the SPVI group and 84.4% in the CPVI group (P=0.0332), with incidence of major complications of 17.5% and 6.7%, respectively (P=0.0845). In the SPVI group, 12.5% patients had pulmonary vein stenosis after the operation, which occurred in none of the patients in the CPVI group (P=0.0312). The total procedure time was 200.4+/-37.0 min in the SPVI group, significantly shorter than that in the CPVI group (226.5+/-26.1 min, P=0.002). The fluoroscopy time in the SPVI group was obviously longer than that in the CPVI group (54.7+/-9.7 vs 27.1+/-3.1 min, P<0.001).

CONCLUSIONSCPVI guided by EnSite NavX system is more effective than SPVI for treatment of atrial fibrillation with significantly shortened fluoroscopy time but prolonged procedure time. The two procedures results in comparable incidences of major complications, but CPVI is associated with reduced rate of pulmonary vein stenosis in comparison with SPVI.

OBJECTIVETo investigate the mechanism of Tougu Xiaotong Granula (TXG) on prevention and treatment of knee osteoarthritis.

METHODSFifty New Zealand rabbits were randomly divided into 6 groups. Except those in the normal control group, all the rabbits were replicated into knee osteoarthritis model using modified Hulth method. They were administered by gastrogavage once every day respectively with 100 ml of normal saline to the rabbits in the normal group and those in the model group, with 10 g of Zhuanggu Guanjie Pill to those in the control group, and 5 g, 10 g and 20 g of TXG to those in the three TXG tested groups (tested group 1, 2 and 3). The levels of interleukin-1 (IL-1), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha) and metalloproteinase 3 (MMP-3) in joint fluid, the blood content of malondialdehyde (MDA) and nitric oxide (NO) absorbance as well as the SOD activity in synovia were observed.

RESULTSOverexpressions of IL-1, IL-6, TNF-alpha and MMP-3 in joint fluid, increased blood content of NO and MDA were shown in the 8th and 16th week, and decreased SOD activity in synovia was shown in the 16th week of the experiment in all the model rabbits, as compared to those in the normal group, the difference was significant respectively (P < 0.05 or P<0.01). After 8 weeks of treatment, the levels of IL-1, TNF-alpha, MMP-3, NO and MDA in the control group, tested group 2 and 3 were significantly different to those in the model group respectively (P < 0.05, P < 0.01), and significant difference was also shown in the comparisons of those indexes between the control group and the tested group 1 vs the tested group 3 (P < 0.05). As for the level of IL-6, significant difference was shown in comparisons of the model group with the control group, tested group 2 and 3 in the 8th and 16th week of the treatment (P < 0.05 or P < 0.01), also in comparison of the tested group 3 with the tested group 1 in the 8th week, and in that of the tested group 2 with the control group and the tested group 1 in the 16th week (P < 0.05).

CONCLUSIONTXG could effectively postpone the degeneration of cartilage through effectively inhibiting the biological effects of cytokines, MMP-3 and oxygen free radical.

During the follow-up for 9-/+3 months, the success rate of initial ablation was 89.5%, and the incidence of procedure-related complications were 7.9%.

CONCLUSIONSCircumferential pulmonary vein ostial isolation guided by EnSite NavX three-dimensional electrophysiological mapping can be effective and safe for AF treatment.

OBJECTIVETo study cortical neuron injury following recurrent epileptiform discharges induced by magnesium-free treatment in vitro.

METHODSCultured embryo cortical neurons were exposed to magnesium-free media for 3 h, then they were returned to regular media containing normal level magnesium. At different time after Mg(2+)-free treatment, trypan blue staining and determination of LDH activity were used to determine the cell viability, flow cytometry was applied to measure neuronal apoptosis, and MTT assay to study metabolic rate.

RESULTS(1) Neuronal morphology on light microscopy following Mg(2+)-free treatment showed that there were no prominent alterations. (2) At different time (6, 12, 72 h) after Mg(2+)-free treatment, neuronal viability by trypan blue staining and LDH activity showed modest changes compared with time-matched control in different culture days (6, 12, 17 d) (P > 0.05). (3) Cell apoptosis increased mildly at different time after Mg(2+)-free treatment in neurons cultured for different days, but the increase was not significant (P > 0.05). (4) Metabolic rate decreased at 6 h after Mg(2+)-free treatment (P < 0.05) in neurons cultured for 6 d, and was 86.4% of that of the control; while the rate at 24 h in neurons cultured for 12 d and 17 d also decreased (P < 0.05), being 78.7% and 70.9%, respectively, of that of the control.

CONCLUSIONSThese findings demonstrated that the injury occurred on cultured cortical neurons caused by magnesium-free-treatment-induced recurrent epileptiform discharges was mainly functional and relatively mature neurons displayed more severe and much later mitochondrial function impairment than immature neurons.
