ABSTRACT
ObjectiveTo summarize the modeling methods, test indicators, and evaluation methods of the animal models of urticaria and provide a basis for the subsequent research on urticaria models. MethodWith the keywords of "urticaria" and "animal model" and the time interval from inception to July 13, 2022, relevant articles were retrieved from CNKI, Wanfang Data, VIP, CBM, Web of Science, Embase, and PubMed. Two evaluators independently screened the articles and extracted the publishing time, sources, animal conditions, modeling methods, modeling time, and test indicators from the articles meeting the inclusion criteria to establish a data library for quantitative statistics and analysis. ResultA total of 116 articles were included, involving 129 animal experiments (102 in Chinese and 27 in English) of urticaria. In the last three years, the studies about the animal models of urticaria presented an obvious upward trend, and the articles were dominated by dissertations. KM mice and SD rats of both females and males were mainly used for the modeling of urticaria, and the models were mainly established by passive sensitization of skin for 14-16 days. The models were mainly evaluated based on apparent indicators such as blue-stained lesion area and ear swelling, supplemented by the pathological indicators of the skin and serum. ConclusionAlthough the experimental studies of urticaria are increasing, the modeling methods lack unified modeling standards and have low coincidence with clinical symptoms. Therefore, this paper analyzed the modeling elements and evaluation criteria of urticaria animal models, and proposed that both male and female KM mice (6-8 weeks old) or SD rats (8-10 weeks old) of SPF grade should be preferentially selected for modeling. Active and passive sensitization can be combined for the modeling, and the specific modeling elements such as modeling time and sensitization times need to be further explored. The model evaluation should include four aspects of behavior, appearance, pathology, and immunity.
ABSTRACT
Objective:To evaluate the utilization of antifungal drugs in Nanjing area, and provide clinical reference for the rational use of antifungal drugs. Methods:According to the sales data of antifungal drugs in 34 hospitals in Nanjing area from 2013 to 2015, the utilization of antifungal drugs was analyzed in respects of consumption sum, DDDs and DDC. Results:The consumption sum and use of antifungal drugs increased year by year. The maximum amount of consumption sum growth rate was 41. 13%. Triazole drugs oc-cupied the top of consumption sum during the past three years, and the sales amount accounted for more than 60% of all. In term of consumption sum, voriconazole, fluconazole, itraconazole and caspofungin ranked top 4 of antifungal drugs. Clotrimazole topical prepa-rations and oral itraconazole ranked top 2 of DDDs, and caspofungin, micafungin and voriconazole ranked top 3 of DDC. Conclusion:The clinical application of antifungal drugs continues to increase during 2013 and 2015. Invasive fungal infection is a lethal factor at high risk. Choosing reasonable, effective, safe and economic of antifungal drugs is the first principle in clinical treatment.
ABSTRACT
Objective To investigate the minimum dose of contrast medium when using spectral CT in cranial CTA. Methods Three groups of patients were required to undergo head CTA examination because of their condition,but different doses of contrast agents were injected.Among them,group 30 mL, group B, group 40mL, group C and group 50 mL were A. Results In group A,the lowest rate of excellent image (23.33%), B group, C group had higher rate of excellent image (93.33%, 96.67%), comparison of the data P<0.05; C group the highest rate of adverse reaction of contrast agent (P<0.05),data comparison P<0.05, A group, B group significantly adverse reactions of contrast agent there is no difference between the situation (P>0.05). Conclusion The use of 40 mL iodide contrast medium in the procedure of cranial CTA examination is effective and safe.

ABSTRACT
Objective:To evaluate the utilization of oral hypoglycemic drugs in 34 hospitals of Nanjing to provide clinical reference for the drug rational use. Methods: According to the sales data of oral hypoglycemic drugs in 34 hospitals of Nanjing from 2011 to 2013,the utilization of oral hypoglycemic drugs was analyzed retrospectively in respect of consumption sum,DDDs and defined daily cost ( DDC) by daily dose limit analysis method. Results: The top 3 oral hypoglycemic drugs in the list of consumption sum were acarbose,glimepiride and metformin. In terms of DDDs,glimepiride, metformin and gliclazide ranked the top 3. The consumption sum and DDDs of oral hypoglycemic drugs were increased year by year in Nanjing. The ratio of serial number of consumption sum and DDDs was from 0. 3 to 2. 0. Conclusion: The demanded quantity of oral hypoglycemic drugs is increased year by year from 2011 to 2013. The application conforms to the safe, effective and economic principle. The drugs should be chosen according to the drug characteristics in order to improve the abnormal glucose metabolism and prevent and treat the complications.
ABSTRACT
OBJECTIVE To explore the rational application of aminoglycosides antibiotics.METHODS We randomly selected 520 patients' records of applying aminoglycosides antibiotics from Jan to Dec in 2007.Types of antibiotics,dosages,usage,ways of delivery and periods and combination of medicines were analyzed.RESULTS Out of the 520 cases,the oldest patient was 89 year and the youngest one was 7 years.The application rate of amikacin was the highest(35.6%),which was delivered mainly by iv,the combination of medicines accounted for 92.7%.CONCLUSIONS The application of aminoglycosides antibiotics in our hospital is basically rational.In some cases the improper antibiotics are used and the duration is a little longer,which should be supervised.
ABSTRACT
OBJECTIVE: To investigate the use of antibiotics in medical insured inpatients with lung infection for reference of management of expenditure of antibiotics in the inpatients.METHODS: The data base documents of a total of 685 insured inpatients with lung infection(Jan.2004～Jun.2006) were collected for a statistical analysis in respect of the utilization and expenditure of antibitoics using defined daily dose and the ratio of order of consumption sum to that of DDDs as indexes.RESULTS: Cephalosporins and quinolones took the lead in expenditure and DDDs,accounting for 70.70% of total antibiotics in terms of consumption sum.CONCLUSION: The main factors affecting hospitalization expense were the application of cephalosporins and quinolones,thus emphasis should be paid to the supervising of these factors.
ABSTRACT
OBJECTIVE To learn the situation of cephalosporins used in our hospital,and offer the scientific guidline base for their clinical use.METHODS Statistics methods were used to analyze dosage,sales volume and DDDS of cephalosporins during 2003-2007.RESULTS The usage of the first generation cephalosporins was reduced year by year,but the third generation of compoands cephalosporins and their oxef cephalosporins occupied the main places.The DDDs of cefoperazone/tazobactam usage ranked second for three years(2005-2007),and at the same period their DDDs consumption got top.CONCLUSIONS The situation of the usage of cephalosporins in our hospital is reasonable basically,but more attention should be payed to the usage of the third cephalosporins and their compounds and oxefs.
