ABSTRACT

Seventy two patients with initial cerebral infarction admitted in the Second Hospital of Jiaxing from March 2017 to October 2017 were enrolled. Patients underwent conventional ultrasonography and contrast-enhanced ultrasonography for two-dimensional echo grading and neovascularization grading of carotid artery plaques respectively. There were 113 carotid plaques in 72 patients with cerebral infarction,27 cases recurred after 1 years with 44 patches. The echo grading of recurrence group was mainly grade Ⅰ and grade Ⅱ,the number of Ⅰ,Ⅱ,and Ⅲ plaques was 23,18,and 3,respectively. The echo grading of non-recurrence group was mainly grade Ⅲ,the number of Ⅰ,Ⅱ,and Ⅲ plaques was 36,23,and 40,respectively. The echo grading of carotid artery plaque between the two groups was significantly different (P<0.05). The grade of carotid neovascularization in recurrence group was mainly grade Ⅲ and grade Ⅳ,the number of Ⅰ,Ⅱ,Ⅲ and Ⅳ plaques was 2,5,27 and 10,respectively. The echo grading of non-recurrence group was mainly grade Ⅰ and grade Ⅱ,the number of Ⅰ,Ⅱ,Ⅲ and Ⅳ plaques was 24,52,14 and 9,respectively. There was significant difference in the grade of carotid neovascularization between the two groups (P<0.05). The area under curve(AUC) of echo grade<Ⅱ,echo grade<Ⅲ,neovascularization grade>Ⅰ,neovascularization grade>Ⅱ and neovascularization grade>Ⅲ in predicting the recurrence of cerebral infarction were 0.553,0.641,0.587,0.793 and 0.557,respectively,the AUC of neovascularization grade>Ⅱ was significantly higher than the other four criteria (P<0.01). The recurrence curves of carotid plaques with different neovascularization grades were significantly different (χ2=49.18,P<0.01). Carotid plaque vulnerability evaluated by contrast-enhanced ultrasonography is an effective indicator for predicting recurrence of cerebral infarction.

ABSTRACT

OBJECTIVE: To investigate the reasons for drug shortage in medical institutions of Sichuan province and put forward relevant countermeasures, and to provide reference for establishing supply security mechanism of drug shortage. METHODS: Questionnaire survey was conducted to investigate drug shortage in 78 medical institutions of the province during Jan. 2015-Jun. 2017. Traceability investigation was conducted from manufacturers and distribution enterprises involved in drug shortage. Questionnaire survey and field investigation were combined to analyze the reasons for drug shortage in Sichuan province and put forward countermeasures. RESULTS: Totally 78 questionnaires were sent out to medical institutions with recovery rate and effective rate of 100%. A total of 206 drugs were reported by 78 medical institutions, involving 240 specifications for shortage in total. Totally 140 questionnaires and 68 questionnaires were distributed to the manufacturers and distribution enterprises involved in drug shortage, and the recovery rate and effective rate were all 100%. Combined with the field survey, survey results of shortage drugs of 212 specifications were obtained. From the perspective of manufacturers, the most important factors causing drug shortage were the increase of production cost (66.51%) and circulation cost(26.88%). From the perspective of distribution enterprises,the main factors causing drug shortage were insufficient supply of drugs(75.47%),inventory management(16.51%) and price inversion(11.32%). CONCLUSIONS: Main reasons of drug shortage from manufacturers and distribution enterprises include the increase of production cost and circulation cost, drug price inversion, inventory management and bidding procurement. It is suggested that measures should be taken to improve the bidding and pricing system of drugs, mobilize the enthusiasm of enterprises; improve the early warning mechanism of drug shortage on the enterprises, strengthen information communication; establish the mechanism of drug shortage reserve, organize the emergency production of drug for shortage; strengthen the management of drug shortage supply chain, purify the unhealthy atmosphere in the market; improve the emergency disposal methods of drug shortage, and improve the supply guarantee ability of drug shortage. Departments cooperate to reduce the emergence of drug shortage and ensure the continuous access to safe and effective drugs in clinic.

ABSTRACT

OBJECTIVE: To investigate the situation and reasons of drug shortage in some medical institutions from Sichuan province. METHODS: A questionnaire survey was conducted among 78 medical institutions in Sichuan province by stratified random sampling. The situation of drug shortage were collected from Jan. 2015 to Jun. 2017, mainly including the basic information of medical institutions, drug shortage situation, specific drug shortage information and the reasons for drug shortage. Descriptive analysis of the information collected by the questionnaire was carried out, and Logistic regression analysis of the data by SPSS 20.0 software was adopted to find out the key factors affecting drug shortage. RESULTS & CONCLUSIONS: Totally 78 medical institutions include 13 third-level hospitals, 22 second-level hospitals and 43 primary medical institutions (10 community health service centers, 33 township health centers). A total of 78 questionnaires were sent out, and the recovery rate and effective rate both were 100%. Among them, 68 medical institutions reported 206 shortage drugs totally, involving 240 specifications. The prices of more than 88.34% of the shortage drug were less than 50 yuan. Main types of shortage drugs included anti-infective drugs, central nervous system drugs and cardiovascular system drugs, and most of them were purchased directly through internet. The proportion of temporary shortage (shortage time<3 months) and long-term shortage (shortage time>12 months) was relatively high (more than 68% in total). Drug supply and medical institutions’own factors were two main causes of drug shortage. Logistic regression analysis showed that main factors affecting the time of drug shortage were hospital drug purchase process, location of medical institution and drug purchase price. The main factors affecting the specifications of drug shortage in medical institutions were the process of drug purchase, the limitation of hospital purchase catalogue, primary or non-primary medical institution, comprehensive or specialized hospitals. It is suggested that medical institutions in this region can reduce the drug shortage caused by their own reasons by building a platform for drug information management, optimizing drug purchase catalogues and plans, strengthening the management of pharmacy inventory and establishing a regulatory system for distribution enterprises.

ABSTRACT

Objective To analyze the clinical value of ultrasound-guided percutaneous Lauromacrogol Injection sclerotherapy in the treatment of simple renal cyst. Methods A total of eighty patients with simple renal cyst, who were divided into 40 groups according to the random number table, were divided into two groups from February 2016 to April 2017. The traditional group used traditional open renal cyst unroofing decompression. Ultrasound guided ultrasound guided percutaneous Lauromacrogol Injection sclerotherapy was performed in the ultrasound guided group. The therapeutic effect, operation time and the rate of successful puncture were compared between two groups of simple renal cysts. It needs to compare the volume of the cyst and the quality of life before and after the intervention. Results Ultrasound guided group simple renal cyst treatment effect was higher than the traditional group (P<0.05). The operation time of the ultrasound guided group was shorter than that of the traditional group, and the success rate of the one shot puncture was higher than that of the traditional group(P<0.05). Before the intervention, the volume and quality of life of the two groups were similar. In the ultrasound guided group, the volume and quality of life in the ultrasound guided group were better than those in the traditional group(P<0.05). Conclusion Ultrasound guided percutaneous Lauromacrogol Injection sclerotherapy is of high clinical value in the treatment of simple renal cysts. The utility model can improve the success rate of one puncture, shorten the operation time, and the exact effect can speed up the regression of symptoms and reduce the volume of the cyst. Therefore, this method can improve the quality of life of patients.
