Objective To apply data mining to risk prediction of sudden deafness, and form the association rules.Methods The clinical data of 517 patients with sudden deafness was collected, including the characteristics of 19 attributes: sex, age, season, hypertension, diabetes, heart disease, hypercholesterolemia, atherosclerosis, long-term smoking, alcoholism, mental tension, insomnia, weakness, bedridden, infection, congenital malformation, trauma, tumour and autoimmune diseases. The source database were cleaned, then mapped for mining database. Minimum support to 0.1 and minimum confidence level to 0.9 were set for analysis of association rules. Results One hundred and six strong association rules were formed, and the rules contained the relation between the incidence of sudden deafness and the characteristics of 19 attributes. Conclusion This method is conducive to make the abstract theory of mathematical statistics into useful association rules to guide the practice of disease prevention and control.

Objective Evaluate the feasibility of PTCA and stents by radial artery. Methods we had operated PTCA for 25 cases by radial artery from July 2004 to April 2005. The average age is 63 years old including 40 men and 15 women. Results 67 stents were implanted in 55 patients including 30A cases, 26 B cases and 11C cases. These stents is about 8mm to 33mm in length and 2.5mm to 4.0mm in width. The successful rate is 96%(53/55), and two case was failed, because the guiding wire can not pass by chronic obstruction in LAD all. There is no case by femoral. All the procedures have no heart complications, obstruction of radial artery and vascular complications. Conclusions The way is good for PTCA by radial artery. Its advantages are mild injury, high successful rate and few complications, and the salted hospitals can use the technology successfully.

Objective To evaluate the initial clinical application value of placing the Freka R Trelumina guided DSA. Methods The Freka(R) Trelumina was placed guided by DSA in 10 patients with disease of digestive tract post operation complicated with stomal leak or/and stomal stegnosis or various kinds of patients with gastric emptying disorder. Results The Freka(R) Trelumina could be put 20 cm away from Treize anadesma guided by DSA. The achievement ratio was 90%. The putting time was 1 to 3 weeks. The localization of the Freka(R) Trelumina was well. The process of feeding was successfully. The effectiveness of decompression of stomach intestine was also good. Stomal leak healed up quickly. The appearance of gastric emptying disorder disappeared. Conclusion Placing the Freka(R) Trelumina guided by DSA is a simple, safe and reliable method for jejunum nourishment and gastrointestinal decompression.

Objective:To study the feasibility of extraction of impacted mandibular wisdom teeth using turbine drill and new instruments. Methods: 600 patients with impacted mandibular third molars were divides into 2 groups. A group used turbine drill and new instruments to extract the impacted mandibular third molar. B group used the dental chisel to extract the impacted mandibular third molar. The operation time, intraoperative and postoperative complications were recorded to assess the effects of the methods. Results: The operation time of group A and group B was (22.285±12.025 01) min and (16.115±12.078 62) min respectively. The operation time of group A was shorter(P<0.05). The intraoperative and postoperative complication incidence rate was lower(P<0.05). Conclusion: Turbine drill and new instruments method is superior to dental chisel method in the extraction of impacted mandibular wisdom teeth.

OBJECTIVETo observe analgesic and sedative effect of acupuncture combined with medicine (ACM) on patients undergiong cardiac surgery.
METHODSA total of 50 patients with cardiac surgery from January 2012 to October 2014 were randomly assigned to the conventional analgesia group (group A) and the ACM analgesia group (group B), 25 in each group. Patients in group A were subjected to analgesia and sedation by injecting dexmedetomidine, while patients in group B were subjected to analgesia and sedation by electro-acupuncture [EA, Shenting (GV24); Yintang (EX-HN3)] combined with injection of dexmedetomidine. Morphine hydrochloride injection was performed when analgesia and sedation effect was ineffective in the two groups. The indicators of patients at different time points in the two groups were observed, such as static and dynamic VAS scores, SAS scores, mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SpO2). The injection dosage of dexmedetomidine and morphine hydrochloride, analgesia satisfaction rate, sedation satisfaction rate, the incidences of adverse reactions during treatment such as bradycardia and low blood pressure, mechanical ventilation time, ICU time, and hospitalization expense were observed and recorded in the two groups.
RESULTSThere was no statistical difference in static and dynamic VAS scores, SAS score, MAP, HR and SpO2 between the two groups at different time points (P > 0.05). The injection dosage of dexmedetomidine and morphine hydrochloride was significantly reduced in group B than in group A (P < 0.05). The analgesia satisfaction rate of patients in group B was much higher than that in group A (P < 0.05). The incidence of bradycardia also obviously decreased more in group B than in group A (P < 0.05). There was no statistical difference in patients' sedation satisfaction rate, incidences of low blood pressure, delirium, vomiting; mechanical ventilation time, ICU time, or hospitalization expense between the two groups (P > 0.05).
CONCLUSIONThe analgesia method of ACM could reduce the dosage of traditional analgesic drugs and the occurrence of partial adverse reactions.

Objective To compare the traditional electrophysiological testing with modified methods for differential diagnosis of Radial Tunnel Syndrome (RTS).Methods A total of 87 selected patients were initially diagnosed as Lateral Epicondylitis (LE) or Tennis Elbow (TE) by doctors from the Outpatient Department of Orthopedics and Rehabilitation.Medical history was asked.Patients received physical examination and examinations for the sensory nerve action potential (SNAP) of superficial radial nerve,the compound muscle action potential (CMAP) of radial nerve and needle electromyography (EMG) to record the muscle Motor Unit Action Potentials (MUAPs).Then,the modified methods for CMAP of radial nerve were conducted on the forearm in the neutral,pronation and supination positions.Three values of CMAP latency were compared.RTS was diagnosed when the difference value ≥0.3 ms.The x 2 test was used to compare the positive detectable rates of the two methods for the RTS diagnosis.Results Thirteen out of 87 patients were diagnosed as RTS,among which three had interosseous nerve lesion and one had superficial radial nerve lesion.The traditional EMG failed to diagnose the remaining 9 RTS cases.These patients were finally diagnosed due to their latency difference of radial nerve CMAP ≥0.3ms when their forearms were examined in three positions.Conclusion The modified electrophysiology method shows a higher positive rate for the diagnosis of RTS.(P<0.05).
