Objective To analyze the rationality of emergency medication in the West China Hospital after Lushan earthquake based on the actual drug use of earthquake victims. Methods We applied DDDs and DUI as evaluation index, input data using Excel software, and analyzed if the emergency medication was required for the injury/illness and the rationality of emergency medication. Results Earthquake victims mainly had trauma and wound infection and they were given antibiotics as main treatment one week after the earthquake. Drugs for the respiratory system and digestive system were mainly used in patients who mainly manifested as non-traumatic diseases and internal diseases four weeks after the earthquake. Among 49 kinds of drugs which could be calculated for the value of DUI, injection accounted for a larger proportion than non-injection (59.18% vs. 40.82%). The results showed that, the medication (DUI=1) only accounted for 12.24%; the medication (DUIlt;1, Mean=0.65) accounted for 38.78%, which implied insufficient drug use; the medication (DUIgt;1, Mean=1.77) accounted for 46.94%, which implied drug overuse. Conclusion Medication for every system is basically timely and rational when treating symptoms and causes in the West China Hospital within one month after Lushan earthquake. However, the rationality of emergency medications using DUI=1 under normal conditions still needs to be further verified.
Objective To investigate drug usage and costs of children inpatients with bronchopneumonia in Karamay Central Hospital in 2014 and to provide baseline for evidence-based pharmacy study of single disease in respiratory system. Methods The information of drug use and expenditure of children inpatients with bronchopneumonia were collected from the hospital information system (HIS). We analyzed the data including frequency, proportion and cumulative proportion by Excel 2007 software. Results A total of 890 children inpatients were included, the average age was 1.00±2.17 years old. Among the antibiotics of single therapy, the frequency of amoxicillin and clavulanate potassium for injection was highest. Among the antibiotics of combination therapy, the frequency of macrolides was highest. Conclusion The mainly drugs for treatment of children inpatients with bronchopneumonia in Karamay Central Hospital in 2014 is amoxicillin and clavulanate potassium for injection.
Objective To explore the change of constitution in thyroid diseases of West China Hospital between 2000 and 2012， in order to provide clinical evidence. Methods Clinical data， including gender， age， and pathological diagnosis of patients with thyroid disease who underwent primary thyroid surgery in our hospital from 2000 to 2012 were collected retrospectively and analyzed statistically. Results A total of 9 642 patients were enrolled， including 1 893 male patients and 7 749 female patients. The ratio of male to female patients was 1 to 4.09. In male patients， the proportion of thyroid carcinoma were significantly higher than those of female group （P=0.02）；in male patients younger than 45 group， the proportion of thyroid carcinoma were significantly higher than those of female group （P＜0.01）. There was no statistical difference on the proportion between male and female patients older than 45 group （P=0.90）. Proportion of thyroid carcinoma， especially proportion of papillary thyroid carcinoma （PTC） increased in general. Proportion of Hashimoto thyroiditis （HT） increased in general too. HT with thyroid carcinoma accounted for an increasing proportion of all patients with HT. Proportion of nodular goiter （NG） increased at first and then declined. Proportion of thyroid adenoma （TA） decreased on the whole. Conclusions Proportion of thyroid carcinoma， especially proportion of PTC increase in recent years on the whole in patients underwent surgery. All these changes need to be given sufficient attention.
Objective To study the relationship between the expression ratio of heat shock protein (HSP) 70 to C-fos in organs outside the brain after brain concussion and the time of injury in rats, in order to provide a new visual angle for determining injury time of brain concussion. Methods The model of brain concussion was established through free falling method. Then the rats were executed at 30 minutes, 1 hour, and 3, 6, 12, 24, 48, 96, 168, 240, 336 hours after injury. Immunohistochemistry staining of C-fos and HSP70 were used in the materials from the main organs including heart, liver, spleen, lung and kidney. All related experiment results were studied by using a microscope with image analytical system and homologous statistics. Results From 30 minutes to 6 hours after injury, the proportion of HSP70 immuno-positive cells increased slowly, while the proportion of C-fos immuno-positive cells increased rapidly, and the ratio of HSP70/C-fos positive cells was on the decline. From 6 to 12 hours after injury, the proportion of HSP70 immuno-positive cells rose continuously, while the proportion of C-fos immuno-positive cells started to decrease, and the HSP70/C-fos ratio showed a rising tendency. From 12 to 336 hours after injury, the proportion of HSP70 immuno-positive cells decreased slowly, while the proportion of C-fos immuno-positive cells decreased rapidly, and the HSP70/C-fos ratio was still on the rise. Conclusions The proportion of positive cells and ratio of the two markers in the main organs including heart, liver, spleen, lung and kidney are similar to those in the brain of rats after brain concussion. Observing the proportion of positive cells of the two markers together with their ratio in the main organs outside the brain may provide a reference for the determination of injury time after brain concussion.
Objective Inappropriate drug dosage is a serious problem in pediatrics, mainly due to the lack of clinical evidence in children, suitable preparation formulation, and standardized methods for dose adjustment. A method for evaluating and monitoring appropriate dosage in pediatrics is urgently needed. The drug utilization index (DUI) based on the Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD) has been widely used in the assessment of appropriate dosage in adults. We explored possible methods for assessing appropriate dosage in children. Methods Based on our previous studies, we discuss cDUI in the assessment of appropriate dosage in children as follows: the meaning of cDDD, the establishment of a standardized system, and the classified evaluation of dosage in pediatrics. Results Although the definition of cDDD draws on the concept of defined daily dose (DDD), the meaning of cDDD is different from that of the latter. Specifically, the purpose of cDDD is to evaluate appropriate pediatric dose, while DDD is a unit of measurement. cDDD could be used to assess dose rationality for common and serious pediatric diseases, and would be refined over time. A single cDDD should be assigned per drug and indication and given per drug and route of administration. The influence of age, weight, diagnosis, and administration route on the dosage should be considered. Classified evaluation should be used and weight should be given to the above mentioned factors in order to evaluate the appropriate dose objectively and comprehensively. Conclusion Dosage regulation in pediatrics has an important role in improving medical quality and protecting the safety, effectiveness, and economy of medical therapy in children. The establishment of a cDUI system is a good try in pediatric dosage evaluation. Although there are still defects within this proposed system and methodology, the principle seems feasible.

Objective To comparatively analyze the rationality of emergency medication after Wenchuan earthquake with that after Lushan earthquake in West China Hospital of Sichuan University, based on the use of medicine of the victim’s disease spectrum. Method By using Excel, defined daily dose system (DDDs) and drug utilization index (DUI) were used as the evaluation indexes to analyze the rationality of emergency medication in West China Hospital of Sichuan University within one month after Wenchuan earthquake and Lushan earthquake. Results Within one month after Wenchuan and Lushan earthquake, there were 1 839 and 488 victims treated in the hospital, respectively. Within one month after the two earthquakes, the variation tendency of DDDs of drugs and number of victims was consistent, and the consistency was better in Lushan earthquake than that in Wenchuan earthquake. Among the 60 drugs which DDDs were ranked top five in their pharmacological class (top ten for antimicrobials) in Wenchuan earthquake, the majority of them were injections (injections vs. non-injections: 70.0% vs. 30.0%); the results showed that the medication (DUI=1) only accounted for 10.0%, the medication (DUI<1) accounted for 28.3%, which implied that the use of drugs was insufficient, the medication (DUI>1) accounted for 61.7%, which implied that drugs were overused; the average of DUI was 1.61. And in Lushan earthquake, injections also accounted for a larger proportion than non-injections (63.3%vs. 36.7%); the results showed that the medication (DUI=1) accounted for 15.0%, the medication (DUI<1) accounted for 38.3%, the medication (DUI>1) accounted for 46.7%; the average of DUI was 1.30. Conclusions Base on the DUI, we draw the conclusion that the rationality of emergency drug use and the timeliness of emergency drug supply were better in Lushan earthquake than those in Wenchuan earthquake. But the rationality of using the DUI, which is an evaluation index for normal conditions, to evaluate the emergency conditions still needs to be further verified.
Objective To investigate the awareness of rational use of drug (RUD) on medical workers in hospitals of different ranks, the establishment and execution of relevant strategies in hospitals of different ranks, and the main factors affecting RUD on medical workers, so as to provide references for the generalization of RUD. Methods A certain number of different ranks of hospitals in Chengdu and Zigong were randomly selected by the convenience sample method. Medical workers in each hospital were selected through face-to-face interviews with a self-designed questionnaire. Monte Carlo Chi-square analysis was applied on the hospital ranks and formulation of RUD guidelines, and logistic regression analysis was performed on the awareness of RUD knowledge of the respondents. Results Among 700 questionnaires distributed, 672 were retrieved (response rate 96.0%). The numbers of respondents who were familiar with the Pharmaceutical Affairs Councils (PACs) as well as the Pharmacy and Therapeutics Committees (PTCs) were 217 (32.29%) and 83 (12.35%), respectively. The number of respondents who understood the concept of essential medicine was 502 (74.71%). A total of 441 (61.16%) medical workers had been trained on RUD, 199 (29.61%) medical workers denied there were PTCs in their hospitals, and 60.71% of the medical workers mentioned that the use of drug was monitored and controlled with the feedback in their hospitals. The result of logistic regression analysis indicated that the professional title (P=0.038), awareness of essential medicine (Plt;0.001) and participation of RUD training (P=0.008) were the factors influencing the awareness of RUD. Conclusion Both management and education should be executed at the same time to elevate the level of rational use of drug. In order to increase the level of RUD we should complete monitoring institution and improving RUD awareness of workers. Additionally enhancing the rationality of medication should be performed by establishing guidelines of treatment or medication. Improving personal knowledge, scientific information and medication custom should be performed by standardizing regulations, strengthening management, emphasizing education and promoting communication between doctors and patients.
