OBJECTIVE: To discuss the optimal operation mode for the management of donated drugs.METHODS: The possible problems existed in the management of donated medicines were found out through summarizing our practical experience in the inventory,storage and use etc of the donated drugs.RESULTS & CONCLUSIONS: In the management of donated medicines,emphasis should be attached to the inventory,storage and use of the donated medicines,meanwhile,a sound supervising system for the donation affairs should be set up to standardize the donation behavior,strengthen expiration date management and gradually establish the practical and effective work mode.

The application of precision medicine in cancer treatment is becoming increasingly common as a result of the continuous advancement in basic research and physical techniques.The revolution of radiotherapy techniques, development of multimodal imaging technology, application of biological target dose carving and adaptive radiotherapy, availability of big data-based radiotherapy planning systems, and selection of chemotherapy regimen have all made the treatment of nasopharyngeal carcinoma increasingly precise.The growing interaction between laboratory research and clinical practice not only underscores the importance of translational medicine, but also prompts the development of biological immunotherapy and screening of prognostic factors.As a result, these changes mark the beginning of a new era for the diagnosis and treatment of nasopharyngeal carcinoma.This review provides a summary from 61 articles on the current progress in translational study and clinical application of precision medicine in nasopharyngeal carcinoma.

To determine the ATPase activity of erythrocytic membrane and intraerythrocyticionic concentrations in 20 patients with chronic renal failure (CRF). Methods: Erythrocyte membrane AT-Pase activites were determined as described by Sha1ev, and erythrocyte Na+ and Ca2+ concentrations weredetected by atomic absorption spectrophotometry. Results: The Na+-K+-ATPase, Ca2 t -ATPase, Mg2+ATPase activities were significantly lower in CRF patients than in normal individuals (P

Objective To understand the situations of home establishments and the related domestic behaviors that causing injuries. Methods A total of 9760 families with regular residents in a community in Shanghai were investigated. Questionnaire was designed bascd on the Guidelines for Conducting Community Surveys on Injuries and Violence and International Classification of External Causes of Injuries. Results Inside the home settings, relative factors were found on issues as fire protection and using of electricity. In terms of household settings, 14.85% of the families had smoke alarm systems in the kitchen; 40.75% had no windows set for emergence. 50% to 70% of the residents had the idea of safe behaviors, including 35.93% of the families stored cleaning products,other chemicals or medical substances in alternative containers, such as used drinking bottle. Only 1.81% of the people being investigated thought that home was also a high risk place where injury might occur and it was placed number 9 in a multiple choice questionnaire. Data from the multiple level model analysis showed that factors as number of family members, space, education, profession etc. were closely related to the situation of home settings and their resident's behaviors. Conclusion Many injury related factors were found related to home establishments and people' s daily behaviors at home which called for interventions to be taken.

Effect of strophanthidin (Str) on intracellular calcium concentration ([Ca2+]i) was investigated on isolated ventricular myocytes of guinea pig. Single ventricular myocytes were obtained by enzymatic dissociation technique. Fluorescent signal of [Ca2+]i was detected with confocal microscopy after incubation of cardiomycytes in Tyrode's solution with Fluo3-AM. The result showed that Str increased [Ca2+]i in a concentration-dependent manner. The ventricular myocytes began to round-up into a contracture state once the peak level of [Ca2+]i was achieved in the presence of Str (10 μmol·L-1), but remained no change in the presence of Str (1 and 100 nmol·L-1). Tetrodotoxin (TTX), nisodipine, and high concentration of extracellular Ca2+ changed the response of cardiomycytes to Str (1 and 100 nmol·L-1), but had no obvious effects on the action of Str (10 μmol·L-1). The elevation of [Ca2+]i caused by Str at all of the detected concentrations was partially antagonized by rynodine (10 μmol·L-1) or the removal of Ca2+ from Tyrode's solution. In Na+, K+-free Tyrode's solution, the response of cardiomycytes in [Ca2+]i elevation to Str (10 μmol·L-1) was attenuated, while remained no change to Str (1 and 100 nmol·L-1). TTX, nisodipine, and high concentration of extracellular Ca2+ changed the response of cardiomycytes to Str at all of the detected concentrations in Na+, K+-free Tyrode's solution. The study suggests that the elevation of [Ca2+]i by Str at the low (nomomolar) concentrations is partially mediated by the extracellular calcium influx through Ca2+ channel or a "slip mode conductance" of TTX sensitive Na+ channel. While the effect of Str at high (micromolar) concentrations was mainly due to the inhibition of Na+, K+-ATPase. Directly triggering the release of intracellular Ca2+ from sarcoplasmic reticulum (SR) by Str may be also involved in the mechanism of [Ca2+]i elevation.

Objective To investigate the pregnancy outcomes of couples with either maternal or paternal balanced translocations.Methods One hundred and ninety-four couples were divided into three groups based on the kind of translocations:135 with reciprocal translocation,52 with nonhomologous Robertsonian translocations,and 7 with homologous Robertsonian translocations.Past reproductive histories were surveyed.For those who wanted to have their own babies by natural conceptions after knowing their karyotypes as well as the risks of abnormal offsprings,subsequent pregnancy outcomes were recorded.Total pregnancy outcomes were compared between three groups.Results(1)503 previous and subsequent pregnancies were recorded in detail.The pregnancy outcomes are as follows:spontaneous abortions 81.7% (411/503);induced terminations because of fetal abnormalities 3.2%(16/503);birth defects 7.2% (36/503);normal/balanced offsprings 8.0%(40/503).In reciprocal translocations,nonhomologous Robertsonian translocations and homologous Robertsonian translocations,the birth defects rates were 5.7% (20/350),10.9%(14/128)and 8.0%(2/25),respectively(P

To analyze the reasons of impaired vision after LASlK and explore its preventive treatment measures preliminarily.METHODS: ln this retrospective study, 175 eyes of 134 patients whose vision was decreased after LASlK were included. The constituent ratio of every reason was counted and uncorrected visual acuity ( UCVA ) between pre-treatment and post-treatment were compared by paired t-test respectively.RESULTS:The overall incidence of impaired vision after LASlK was 1. 86%. The constituent ratio of regression was 51. 43% and UCVA increased from 0. 61±0. 22 to 0. 90±0. 38 (t=8. 00, P<0. 001) after treatment. The constituent ratio of punctate corneal epithelial defect was 32. 57% and UCVA increased from 0. 60±0. 19 to 1. 20±0. 24 (t=20. 00, P<0. 001 ) after treatment. The constituent ratio of accommodative spasm was 5. 14% and UCVA increased from 0.76±0. 21 to 1. 32±0. 22 (t=8. 14, P<0. 001) after treatment. The constituent ratio of corneal flap shift and gauffer was 4% and UCVA increased from 0. 29 ± 0. 26 to 1. 24 ± 0. 28 ( t = 6. 33, P<0. 001 ) after treatment. The constituent ratio of corticosteroid - induced ocular hypertension was 4% and UCVA increased from 0. 57±0. 05 to 1. 0 ± 0. 16 ( t= 2. 53, P<0. 05 ) after treatment. The constituent ratio of fundus lesions and diffuse lamellar keratitis ( DLK) was 2. 86% and UCVA all increased by different degrees after treatment.CONCLUSlON: The reasons of impaired vision after LASlK are many and varied. These cases could recover their vision by discovery and treatment in time, and the appropriate preventive measures were essential.
