Objective To explore the clinical study of surgical treatment of the senile acute cholangitis severe type in old person.Methods According to the relationship between the senile pathophysiologic characteristics and senile acute cholangitis severe type(ACST),83 patients were selected to the study.Results In operation group with which included 83 cases,4 cases were died,the total mortality is 5.0%.Rate of remnant stone is 15.0%.Ulcer was healed in 79.0%,significantly improved in 14.0%and poor in 9.0%of patients.Conclusion When conditions turned to be stable,operation should be done in time.The main Causes of death of senile ACST are the delay of operation,severe complications and old man.

Objective To explore the characteristics of treatment of gallstone ileus.Methods According to the relationship between the senile pathophysiologic characteristics and senile acute cholangitis severe type(ACST),83 patients were selected to analyze.Results In operation group,which included 83 cases,4 cases were died,the total mortality is 5%.Rate of remnant stone is 15%.Ulcer was healed in 79%.significantly improved in 14% and poor in 9% of patients.Conclusion When conditions turned to be stable.operation should be done in time.The main causes of death of senile ACST are the delay of operation,severe complications and old man.

Objective To connect with provincial or even national report center for adverse events of medical instruments and set up a computer-aided system for supervision.Methods By designing software,setting up database and online connecting with report center,the computer-aided system for adverse events of medical instruments was utilized to automatic report,early-warning monitoring and report.Key technologies were analyzed.Results Based on computer network,adverse events of medical instruments were automatically reported,collected and managed.Information and consultation could be provided rapidly without error.Conclusion The system not only facilitates management department in medical instruments managing,producing and application,but set a theoretic basis for development and academic teaching of new medical instruments.

Objective To develop a medical tilting-table for recovery training of paralysis patients (including paraplegia, hemiplegia and quadriplegia). Methods Renesas 16-bit microcontroller, R8C/25, was used as controller. Danish Linak31 was used to drive the bed. Nixie tube was used to display prescription, angle of tilting table, treating time and music list. Results It worked stable with well-controlled angle. The error was only 1?. The display of nixie tube was good and stable. MP3 played well. Back-up power could provide power supply timely and stably in power failure. Conclusion Medical tilting-table has been successfully applied in clinic.

Objective To retrospectively analyse the anaesthetic management of Norwood Stage Ⅰ.Methods Between June 2010 and August 2014, totally 5 small infants with HLHS underwent the standard Norwood Stage I procedure .They were all boys.Age at surgeries ranged from 29 to 75 days with median 36 days, and weight from 2.57 -3.50 kg with median of 3.13kg.The first three cases were received intravenous prostaglandin E1 before they were sent to the operation theatre and were under mechanical ventilation .They were received emergent operations because of unstable hemodynamic situation .The other two cases were relatively stable without mechanical ventilation and were received restrict surgery .All 5 cases received the stand-ard Norwood Stage Ⅰprocedure under intravenous-inhalation balance-general anaesthesia with cardiopulmonary bypass.The technique of deep hypothermia and circulatory arrest were used in all five cases .Results The fourth case died from low cardi-ac output syndrome after cardiopulmonary bypass .The other 4 cases were transferred to the paediatric intensive care unit after withdrawal from bypass.One of the four cases died after 32 h after surgery.Conclusion The standard Norwood Stage Ⅰ pro-cedure is aquite complex procedure, which demands multidisplinary cooperation, to palliatively correct HLHS.We retrospect the experiences of the anesthetic management in our centre and hope it will be helpful to decrease the mortality and morbidity in relatively short period.

This paper summarized the clinical experience of XU Fengqin in the treatment of hypertension in the elderly. It is believed that the basic pathogenesis of hypertension in the elderly is liver and kidney depletion， and the key is ascendant hyperactivity of liver yang and spleen failing to transport. Therefore， the theory of “combination of disease and symptoms” is put forward that the four common clinical symptoms of hypertension in the elderly， including morning hypertension， non-dipper hypertension with abnormal circadian rhythm， postprandial hypotension and orthostatic hypotension， should be differentiated and treated with prescription in accordance with the characteristics of the corresponding pathogenesis. Specifically， the pathogenesis of morning hypertension is mainly liver-kidney yin deficiency and ascendant hyperactivity of liver yang， for which the treatment method of enriching liver and boosting kidney， calming the liver and subduing yang is suggested， and Qingxuan Jiangya Decoction （清眩降压汤） in modifications can be used. For non-dipper hypertension with abnormal circadian rhythm， the pathogenesis is mainly phlegm-dampness obstruction and clear yang failing to ascend， and treatment method should be dissolving phlegm and dispelling dampness， calming the liver and extinguishing wind， with Banxia Baizhu Tianma Decoction and Modified Honglong Xiahai Decoction （半夏白术天麻汤合加味红龙夏海汤） in its modifications. Regarding postprandial hypotension and orthostatic hypotension， the pathogenesis is mainly spleen-stomach depletion and clear yang failing to ascend， and thus the method of supplementing the center and boosting qi， raising yang and lifting the sunken is advised with Buzhong Yiqi Decoction （补中益气汤） or Yiqi Congming Decoction （益气聪明汤） in the modifications.
