Objective To investigate the clinical characteristics and summarize the experiences on the diagnosis and treatment of gastritis cystica profunda (GCP).Methods Clinical data of 15 GCP patients,who were treated in the First and Second Affiliated Hospital of Zhengzhou University from January 2006 to January 2013,were retrospectively analyzed.Results GCP may present clinically as abdominal pain,bloating,emaciation,and GI bleeding.CT,electronic gastroscope,or ultrasonic endoscope shows that GCP consists of multiple cysts within a thickened submucosal layer.The submucosal pathological features can not be obtained by ordinary biopsy and snares.Of the 15 cases,proximal gastrectomy was performed in 4 cases,distal subtotal gastrectomy in 3 cases,1 case was treated with gastric wedge resection,and total gastrectomy was performed in 7 cases.Postoperative recovery was uneventful.13 cases were followed up for 2 years,and there was no evidence of recurrence.Conclusions GCP is an uncommon disease with unknown origin,and has no clinical characteristics,and has malignant potential.Postoperative prognosis is satisfactory.

AIM To establish an ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for the simultaneous content determination of gallic acid,matrine,danshensu,hydroxysafflor yellow A,caffeic acid,paeoniflorin,ferulic acid and cynaroside in Xuebijing Injection (Carthami Flos,Paeoniae Radix Rubra,Chuanxiong Rhizoma,etc.).METHODS The analysis of 5％ acetonitrile extract of this drug was performed on a 40 ℃ thermostatic ACQUITY UPLC(C) BEH C18 column (2.1 mm × 50 mm,1.8 μm),with the mobile phase comprising of acetonitrile-0.1％ formic acid flowing at 0.2 mL/min in a gradient elution manner,after which cluster analysis was applied to the determined contents.RESULTS Eight constituents showed good linear relationships within their own ranges (r ＞ 0.996 0),whose average recoveries were 95％-104％ with the RSDs of less than 3％.Generally the contents of various constituents in ten batches of samples were found to be stable except the certain differences contributed by gallic acid and paeoniflorin.CONCLUSION We should pay attention to the quality of different batches of Xuebijing Injection due to their uneven performance.

OBJECTIVE:To provide reference for standardized management of skin test of cephalosporin injection in our hos-pital. METHODS:In retrospective analysis,skin test of 8 kinds of cephalosporin [cefotaxime(1.0 g),cefotaxime(0.5 g),cefoti-am (1.0 g),cefotiam (0.5 g),ceftazidime (0.5 g),cefminox (0.5 g),cefminox (1.0 g),ceftriaxone (1.0 g)] and the cost of skin test, related cost of allergic reaction induced by cephalosporin injection were analyzed statistically during Sept. 1st, 2015-Aug. 31th,2016. The cost of skin test of cephalosporin injection was compared with allergic reaction cost reduced by skin test. RESULTS:The positive rate of 100330 patients who used above 8 kinds of cephalosporin injections was 6.27%;the rate of skin test was 82.49%;the direct cost of skin test was 3434411.72 yuan;the indirect cost was 141985.12 yuan;the cost of pa-tient was 3162901.44 yuan;the cost of medical insurance was 259096.28 yuan;the cost of the whole society was 3576396.84 yuan. From the perspective of the whole society,the cost of skin test of cephalosporin injections was(447049.61±247395.07)yuan, and allergic reaction cost reduced by skin test was (316075.48 ± 260600.49)yuan. The cost of skin test was significantly higher than allergic reaction cost reduced by skin test,with statistical significance(P<0.05). CONCLUSIONS:Skin test of cephalosporin injection is low in positive rate,has high expense. The government standardizes the management of skin test of cephalosporin injec-tion and reduces the economic burden of patients under the premise of ensuring the safety of drug use.

OBJECTIVE:To investigate the situation and influential factors of hospital pharmacist career planning and career satisfaction and their relationship. METHODS:The questionnaire modified according to"general career planning and career satisfaction scale"was adopted for questionnaire survey among pharmacists in 5 third grade class A hospitals by simple random sampling. The factor analysis was used to test the reliability and validity of the questionnaire. The influential factors of career planning and satisfaction degree,the relationship of career planning with satisfaction degree were analyzed by multiple regression analysis and Spearman correlation coefficient. RESULTS:Totally 210 questionnaires were sent out and 198 were effectively received,with effective recovery of 94.28%. Cronbach'α value of reliability and validity test was 0.939(>0.6),and KMO value was 0.905(close to 1). Results of survey showed that there was statistical significance in the effects of gender,age,marital status, work experience,professional title and position on career planning(P<0.05). There was statistical significance in the effects of age and professional title on satisfaction degree(P<0.05). Different dimensions of career planning(self-assessment,career awareness and action,position questions)were positively correlated with career satisfaction degree(total correlation coefficients were 0.649,0.633,0.694). CONCLUSIONS:Career planning is mainly influenced by gender,age,marital status,work experience,professional title and position. Career satisfaction degree is greatly influenced by age and position.The better the career planning is,the higher the satisfaction is. It is suggested to conduct professional training of hospital pharmacists by referring to the theory and experience of management,help pharmacists to fully understand the job responsibilities and do a good job in the position of professional roles. The establishment of scientific and effective career planning management system improves self-management ability of hospital pharmacists and career satisfaction degree,and promotes the development of discipline.

Fluoroquinolones are widely used in clinical practice, but their clinical application in juvenile patients has been controversial.The purpose of this study was to investigate the pharmacokinetic characteristics, indications and adverse reactions of Ciprofloxacin and Levofloxacin in minors.It is shown that the two drugs are effective for infectious diseases and no serious or persistent joint or skeletal muscle injury occurs in minors using the drugs.Hence, in the absence of alternatives, the benefits of Ciprofloxacin or Levofloxacin treatment for minors may outweigh the risks.
