BACKGROUND:An electronic moxibustion apparatus that simulates the mechanism of traditional moxibustion therapy is designed and developed to overcome shortcomings of traditional moxibustion therapy, such as non-standardized treatment, limited body position, and production ofsmokeandashduring the treatment.
OBJECTIVE:To develop a kind of electronic moxibustion apparatus which simulates the traditional moxibustion therapy and has obtained the patent so as to industrialize and modernize moxibustion therapy.
METHODS:Bio-waves launched from far infrared materials are beneficial to the human body. An electronic moxibustion apparatus including time temperature control er and moxibustion head was developed, and the closed loop control technique was used to precisely control the temperature and time. Thermal radiation infrared spectrum that moxibustion head generated could simulate the emission spectrum of moxibustion in combination with wormwood oil coating or drug interval, thereby achieving the therapeutic effect similar to traditional moxibustion.
RESULTS AND CONCLUSION:The prototype of DZWJY-1 electronic moxibustion instrument has been developed and its safety and electromagnetic compatibility have been detected in Shanghai Testing&Inspection Institute for Medical Devices, China. Relevant clinical trials are ongoing to verify the efficacy. Preliminary clinical evidence shows that the electronic moxibustion apparatus has the same therapeutic effect to the traditional moxibustion therapy, which realizes the safety and environmental protection of moxibustion therapy and provides objective, standardized and modernized evidence for moxibustion therapy

This article was aimed to study the latest research progress of Tripterygium hypoglaucum, in order to pro-vide references for further research on T. hypoglaucum. CNKI Chinese Journal Full-text Database was used as data source. Bibliometric analysis was conducted on T. hypoglaucum research articles issued from 1915~2013. Bibliometric method was used in the analysis on the change trend among years, research institutes, publication dates, research per-sonnels and research topics of the articles with the built-in analysis tools and network analysis tools. The results indi-cated that T. hypoglaucum research was still in the development stage. And there is still plenty of room for growth in aspects including resources, material basis, manufacturing pharmacy and so on.

Objective To evaluate the effect of sildenafil on the expression of tumor necrosis factor-alpha (TNF-α) in lung tissues of rats with pulmonary hypertension.Methods Twenty-four male Sprague-Dawley rats,aged 8 weeks,weighing 180-220 g,were randomly divided into 3 groups (n =8 each) using a random number table:control group (group C),pulmonary hypertension group (group PH),and sildenafil group (group S).Sildenafil 50 mg/kg was injected through a gastric tube into stomach once a day for 35 consecutive days starting from 1 day after lelf pneumonectomy in group S.Pulmonary hypertension was induced by left pneumonectomy and subcutaneous monocrotaline injected at 7 days after operation in PH and S groups.At 35 days after operation,mean pulmonary arterial pressure (mPAP),relative medial thickness of pulmonary artery (RMT),right ventricular systolic pressure (RVSP),and muscularization of small pulmonary arteries were measured in the lung.The ratio of the right ventricular weight to the sum of the weights of the left ventricle and septum (RV/(LV + S)) was calculated.The expression of TNF-α mRNA and protein was determined using RT-PCR and Western blot analysis,respectively.Results Compared with group C,mPAP,RVSP,muscularization of small pulmonary arteries,RMT and RV/(LV + S) ratio were significantly increased,and the expression of TNF-α mRNA and protein was upregulated in group PH,and RVSP,muscularization of small pulmonary arteries and RV/(LV + S) ratio were increased in group S.Compared with group PH,mPAP,RVSP,muscularization of small pulmonary arteries,RMT and RV/(LV + S) ratio were significantly decreased,and the expression of TNF-α mRNA and protein was downregulated in group S.Conclusion Sildenafil can down-regulate the expression of TNF-α in lung tissues of rats with pulmonary hypertension,inhibit reconstruction of pulmonary artery,and decrease the pulmonary arterial pressure.

The MRI data of 13 patients with autoimmune pancreatitis (AIP) were retrospectively analyzed. The results showed that the pancreas diffusely enlarged in 10 of 13 cases, and focally enlarged in 3cases. There were 13 cases with decreased signals on T1WI and mildly hyperintense on T2WI in the area with pancreatic lesions, 11 cases with thickened capsule-like structure showing moderate-low signal T1WI and low signal T2WI,and delayed enhancement in dynamic contrast-enhanced MRI, and 10 cases with stenotic common bile duct at the level of pancreas with proximal cholangiectasis. The findings in 9 cases were remarkably improved in followup MRI after glucocorticord treatment.

Objective To evaluate the effect of penehyclidine hydrochloride on cell apoptosis during acute lung injury (ALI) induced by two-hit in rats.Methods Thirty male SPF Sprague-Dawley rats, aged 8 weeks, weighing 240-270 g, were randomly assigned into 3 groups (n =10 each) using a random number table: sham operation group (group Sham), ALI induced by blunt chest trauma and hemorrhagic shock group (group ALI), and penehyclidine hydrochloric group (group PHC).In ALI and PHC groups, the rats were subjected to the combination of chest trauma and hemorrhage (mean arterial pressure 35-40 mmHg mm Hg, lasting for 60 min) to establish a model of ALI.In group PHC, penehyclidine hydrochloric 2 mg/kg was injected intraperitoneally at 1 h before blunt chest trauma.At 8 h after successful establishment of the model, the rats were sacrificed, and lungs were removed for examination of the pathologic changes and for determination of Bax, Bcl-2 and caspase-3 expression (using Western blot), tumor necrosis factor-alpha (TNF-α) content (by enzyme-linked immunosorbent assay) , and cell apoptosis (by TUNEL).Apoptotic index was calculated.Results Compared with group Sham, the levels of Bax, caspase-3 and TNF-α and apoptotic index were significantly increased, and Bcl-2 expression was down-regulated in ALI and PHC groups.Compared with group ALI, the levels of Bax, caspase-3 and TNF-α and apoptotic index were significantly decreased, and Bcl-2 expression was up-regulated in group PHC.The pathologic changes of lungs were significantly reduced in group PHC than in group ALI.Conclusion Penehyclidine hydrochloride mitigates ALI induced by two-hit through inhibiting cell apoptosis in rats.

Objective To evaluate the value of computed tomography(CT) and magnetic resonance imaging(MRI) in diagnosis of avascular necrosis of the femoral head(ANFH). Methods The literatures of ANFH diagnosed with CT and MR imaging published in the last ten years were collected by searching. Of that,21 literatures were correspond for the standards in this study and were select-ed. These literatures in diagnosing ANFH with CT and MR imaging were analysed with Meta-analysis by the sofeware of StataSE10.1. Results MRI was more effective than CT in diagnosing ANFH. There was significantly different in statistics between them [OR=0.13,95%CI(0.03～0.51)]. Conclusion In comparison with CT,MRI is the better method in diagnosing ANFH.
