Long-term effects of autogenous coronoid grafts on the facial growth of children with unilateral temporomandibular joint ankylosis and reconstructed mandibular condyle / 华西口腔医学杂志

OBJECTIVE@#Mandibular condyle injury usually results in malocclusion and disharmony of facial growth in growing children. This study aimed to evaluate the long-term effects of autogenous coronoid grafts on the facial growth of children with unilateral temporomandibular joint (TMJ) ankylosis who underwent mandibular condyle reconstruction.@*METHODS@#Ten growing patients with unilateral bony TMJ ankylosis admitted in West China Hospital of Stomatology, Sichuan University between January 1st, 2008 and December 31st, 2016 were followed up and evaluated. These patients include three males and seven females with ages ranging from 5 years to 12 years at the time of surgery. Each patient underwent gap arthroplasty, condyle reconstruction with ipsilateral coronoid, and interposition of the pedicled temporalis fascial flap in a single operation. The postoperative follow-up ranged from 3 years to 8 years with an average of 4.9 years. Postoperative panoramic radiographs determined the growth of the mandibular height and length on the affected side and compared it with those of the healthy side.@*RESULTS@#All patients recovered uneventfully after surgery. At the end of follow-up period, the maximal mouth opening ranged from 32 mm to 41 mm with an average of 35.6 mm. Mandibular height and length continued to grow after the successful treatment of ankylosis using autogenous coronoid grafts for condyle reconstruction. However, growth deficit still existed. The final ramus height and mandibular length of the affected side at the end of follow-up increased by 25.3% (P<0.05) and 26.1% (P<0.05), respectively, compared with the initial values measured immediately after surgery. Growth rates of ramus height and mandibular length of the affected side were 47.1% and 27.2% lower (P<0.05) than those of the healthy side, respectively.@*CONCLUSIONS@#Mandibular height and length continued to grow after the successful treatment of ankylosis by using autogenous coronoid grafts for condyle reconstruction. However, growth deficit still existed. The growth rate of the affected mandible was reduced compared with that of the undisturbed side even after treatment of ankylosis.

Research and application of intelligent error correction system for medical service pricing at public hospitals / 中华医院管理杂志

Deepening healthcare reform highlights the importance of medical services pricing adjustment, and the imperativeness to strengthen the informationized management of such pricing.With this concept in mind, the authors analyzed the problems and causes of the current management on medical service pricing informatization at public hospitals, and discussed the construction strategy of an intelligent error correction system in this regard. That is, to develop a technical process from the four aspects of software flow, interface flow, project rules, and reporting system. This system is designed with such functions as inpatient cost inquiry, inpatient information, price adjustment analysis, price feedback record statistics and inquiries over the hospitalization expense ceiling, as well as inpatient cost omission inquiry.This paper also discussed the construction of a platform to transform the knowledge of pricing policy into the knowledge base of medical service pricing, in order to improve the level of medical pricing management, promote the efficiency of hospital operation and management, and reduce the burden of patients.

Research progress in tumor with cardiovascular disease / 实用肿瘤学杂志

In recent years,the incidence of cancer has shown a upward trend and has become one of the major diseases af-fecting human health and life safety. With the continuous improvement of diagnosis and treatment levels,the prognosis of cancer pa-tients has been significantly improved,and its five-year survival rate has been significantly enhanced. Although the patient′s life span has been extended,a series of problems have also arisen. The development of the tumor itself will involve other systems,and there are certain side effects during the treatment process,such as chemotherapy and radiotherapy,which will lead to the corresponding lesions in other systems of patients,the most common is the cardiovascular system. Furthermore,with the improvement of life quality,there are also patients with cancers and cardiovascular diseases. This article reviews the research on the common molecular mechanisms of tumor and cardiovascular disease,the combination of clinical treatment and the intervention of common risk factors,and puts forward the prospect.

Diatom Detection Using Enzyme Combined with Strong Acid Digestion Method / 法医学杂志

OBJECTIVES@#To detect diatom in the organs of drowners by enzyme combined with strong acid digestion method, and evaluate its application value.@*METHODS@#A total of 40 cases which have been identified as drowning in local region were collected. Samples of the lung, liver, kidney, and the water of the scene were also gathered from each case. Strong acid digestion method, enzyme combined with strong acid digestion method, and enzymic digestion method were respectively performed to detect the diatom in the samples. The comparative analysis was made on digestion time, digestive power and detection rate of diatom, etc.@*RESULTS@#Enzyme combined with strong acid digestion method was significantly better than enzymic digestion method on digestion time and digestive power; enzyme combined with strong acid digestion method were obviously superior to strong acid digestion method on the detection rate of diatom.@*CONCLUSIONS@#Enzyme combined with strong acid digestion method combines the advantages of strong acid digestion method and enzymic digestion method. It has the characters of operation safety with little pollution to environment, which is worthy of further popularization and practice.
