ABSTRACT
OBJECTIVE@#To evaluate clinical effect of poking reduction cannulated screw based on Pingle orthopedic muscle-bone interoperability balance theory in treating Sanders Ⅱ calcaneal fracture.@*METHODS@#From October 2014 to December 2017, 28 patients with Sanders Ⅱ calcaneal fracture were treated with poking reduction cannulated screw guided by Pingle orthopedic muscle-bone interoperability balance theory, including 20 males and 8 females, aged from 24 to 55 years old with an average of (37.2±3.9) years old. Calcaneal width, Bhler angle, and Gissane angle were measured before and after operation, and Maryland Score before and 6 months after operation were compared.@*RESULTS@#All patients were followed up from 12 to 16 months with an average of (13.7±1.3) months. All fractures healed normally, and healing time ranged from 9 to 12 weeks with an average of (10.2±1.3) weeks. No postoperative wound infection, cortical necrosis, or osteomyelitis occurred. The width of the calcaneus decreased from (34.15±2.58) mm before surgery to (30.49±2.37) mm after surgery, Bhler angle increased from (14.16±3.27)° before operation to (31.95±3.07)°after operation, Gissane angle decreased from (128.45±9.04)° before operation to (120.83±8.15)° after operation. Maryland Score was 15.68±4.73 before operation, and was improved to 88.32±2.65 at 6 months after operation;19 patients got excellent result, 6 good, 2 fair and 1 poor.@*CONCLUSION@#Poking reduction cannulated screw based on Pingle orthopedic muscle-bone interoperability balance theory in treating Sanders Ⅱ calcaneal fracture has certain clinical effects, high acceptation of patient, and without special demand for soft tissue around fracture. But it should avoid choosing severe comminuted Sanders Ⅲand Ⅳcalcaneal fracture.

<p><b>OBJECTIVE</b>To study the effects of glycyrrhetinic acid (GA) on the sodium ion channel currents (I(Na)) of rats' ventricular myocardial cells, and to explore its anti-arrhythmic mechanisms at the ion channel level.</p><p><b>METHODS</b>Single ventricular myocardial cells was isolated from SD rats. The whole cell patch clamp was used to record the effects of GA on I(Na) of rats' ventricular myocardial cells.</p><p><b>RESULTS</b>GA could inhibit I(Na) of rats' ventricular myocardial cells dose-dependently. GA at 1, 5, and 10 micromol/L decreased I(Na) of rats' ventricular myocardial cells from (-4.26 +/- 0.15) nA to (-3.54 +/- 0.10) nA, (-2.19 +/- 0.09) nA, and (-1.25 +/- 0.08) nA, respectively. GA at 1, 5, and 10 micromol/L inhibited I(Na) by 16.08% +/- 2.3%, 50.82% +/- 3.56%, and 75.98% +/- 5.12%, showing statistical difference when compared with the control group (P < 0.05). GA at 10 micromol/L shifted I(Na) current-voltage curve more positively, but the activation potential and the peak potential were not changed.</p><p><b>CONCLUSION</b>GA inhibited the I(Na) of rats' ventricular myocardial cells dose-dependently, which was possibly associated with its antiarrhythmia effects.</p>

Ginseng, the root of Panax ginseng C. A. Mayer, has long been used clinically in China to treat various diseases. Multiple effects of ginseng, such as antitumor, antiinflammatory, antiallergic, antioxidative, antidiabetic and antihypertensive have been confirmed by modern medicine. Recently, the clinical utilization of ginseng to treat heart diseases has increased dramatically. The roles of ginseng in protecting heart are foci for research in modern medical science and have been partially demonstrated, and the mechanisms of protection against coronary artery disease, cardiac hypertrophy, heart failure, cardiac energy metabolism, cardiac contractility, and arrhythmia are being uncovered progressively. However, more studies are needed to elucidate the complex mechanisms by which ginseng protects heart. All such studies will provide evidence of ginseng's clinical application, international promotion, and new drug development.

Objective To explore the risk factors and protective factors for stomach cancer in Ganyu county.Methods Data of 319 pairs of new stomach cancer cases and health controls(1:1 matched)were studied by conditional Logistic regression method on the influential factors.Results The main risk factors for stomach cancer were the habits of eating hot foods(OR= 2.21,95%CI:1.57~3.12),the history of upper gastrointestinal inflammation(4.26,2.59~7.03),family history of cancer(2.29, 1.37~3.82);The main protective factors were often eating raw garlic(OR=0.64,95%CI:0.42~0.96),regular drinking tea(0.37, 0.25~0.54).Conclusion Unhealthy dietary habits,the history of upper gastrointestinal inflammation and family history of cancer are related to stomach cancer,while eating raw garlic and regular drinking tea may be effective in preventing the occurrence of stomach cancer.The results could be applied in stomach cancer prevention activities in Ganyu county.
