ObjectiveTo investigate the current situation of postoperative fluid therapy in general surgery department of grade Ⅲ-A general hospitals in Beijing and Tianjin. Methods Postoperative patients in general surgery department who were fasting for 3 days were retrospectively investigated, and 600 cases were recruited without considering age, gender, denomination of disease and operation type.The general information of patients, laboratory examination before and after operation, postoperative fluid therapy for 3 days, postoperative complications and infusion reaction were collected.Results In total 588 valid cases, the volume of average fluids supplement was (3030±638)ml per day, With the prescribed glucose (142+67)g per day, potassium chloride (59.9±23.9) mmol per day and sodium chloride (179.5±66.7) mmol per day. 85.2 % of total patients received nutrition support and the ratio of parenteral nutrition/enteral nutrition (PN/EN) was 28/1.There were 549 patients with BMI>18.5 before operation, and among them, 470 cases (85.6%)received parenteral and enteral nutrition treatment. There were 39 patients with BMI < 18.5 and 27 cases (69.2%) received parenteral nutrition support without enteral nutrition treatment. During the 3 days after operation, there were 36 cases with fluid therapy without potassium chloride supplement.ConclusionsThe proportions of receiving nutrition support and parenteral nutrition treatment are relatively high in grade Ⅲ-A general hospitals in Beijing and Tianjin. Ready-to-use preparation canreduce mistake and will be benefit to patients.

Objective To summarize the clinical characteristics and prognosis of lacrimal gland adenoid cystic carcinoma with high-grade transformation (LACC-HGT).Methods A retrospective study was adopted.Seventeen patients with lacrimal gland adenoid cystic carcinoma (LACC) were collected from August 2008 to March 2017 in Tianjin Medical University Eye Hospital.Hematoxylin-eosin staining and immunohistochemical staining were performed on tumor sections of 17 LACC patients.According to the pathology results,the patients were divided into LACC-HGT group (6 patients) and non-LACC-HGT (NLACC-HGT)group (11 patients),and the clinical characteristics and prognosis of the two groups were analyzed by using Fisher's exact test and Log-Rank test.Results The medical histories,clinical features,imaging features,TNM staging and treatment protocols were not significantly different between the two groups (all at P＞ 0.05).The 2-year local recurrence rate,5-year distant metastasis rate and 5-year death rate of patients with LACC-HGT were significantly higher than patients with NLACC-HGT (all at P＜0.05).Survival analysis results showed that the survival time of LACC-HGT group was obviously shorter than that of NLACC-HGT group.Conclusions LACC-HGT accelerate the invasion process of local recurrence and distant metastasis,and enhance the death rate.The detection of HGT components should be considered in the process of LACC diagnosis.

OBJECTIVE：To evaluate the economy of pe rospirone in the treatment of schizophrenia ，to provide guidance for clinically proper use of medications more cost-effectively ，and related health decision-making . METHODS ：A short-term decision tree model was constructed from the perspective of medical insurance payer to calculate the cost and health outcomes of different treatment plans considering major adverse events including extrapyramidal reaction ，weight gain ，diabetes，hyperlipidemia. The cost-utility of perospirone were compared with quetiapine ，aripiprazole and olanzapine respectively ，using QALYs as the measure of health outcomes ，3 times GDP per capita as the willingness-to-pay threshold ；probability sensitivity analysis was performed. RESULTS：The results of base-case analysis showed that the cost of perospirone （6 688.25 yuan）was lower than those of quetiapine （9 887.45 yuan），aripiprazole（13 284.65 yuan）and olanzapine （15 332.80 yuan）. The utility of perospirone （0.79 QALYs）was better than those of quetiapine （0.76 QALYs），aripiprazole（0.77 QALYs）and olanzapine （0.75 QALYs）. Compared with quetiapine ， aripiprazole and olanzapine ，peropirone had lower cost and higher health outcome ，which indicated that strong dominance favors perospirone over the other 3 drugs. The results of sensitivity analysis were consistent with those of base-case analysis. CONCLUSIONS：Perospirone has economic advantages in treating schizophrenia patients compared to other commonly used atypical antipsychotic drugs.
