2.A new target for gene therapy-splicing factor PUF60
Journal of International Oncology 2017;44(7):531-533
Poly(U)-binding-splicing factor 60 KDa (PUF60), a U2-related splicing factor that facilitates 3′splice-site recognition at the early stage of spliceosome assembly.High expression of PUF60 is related to the occurrence of multiple tumors, such as colorectal cancer, ovarian cancer, gastric cancer, liver cancer, et al.PUF60 can regulate the expression of c-myc through the core-human transcription factor Ⅱ basal transcription factor.Anti-PUF60 antibodies are detected in the sera of patients with early-stage and recurrent tumor, and the levels are significantly decreased after the operation.PUF60 can be used as a combined or independent test index for the diagnosis of cancer, which can be a potential new target for gene therapy.
3.Preparation of Metoprolol Succinate Sustained-Release Tablet and Its Content Determination
Herald of Medicine 2016;35(8):870-874
Objective To establish a method of preparing metoprolol succinate sustained-release tablet and its content determination. Methods The formulation was optimized through the orthogonal design test by using release rate of the drug as an indicator.The different batches of metoprolol succinate sustained-release tablets were determined by HPLC. Results The tablets could release drug steadily and slowly as designed,which was similar to imported tablets. The linear range of metoprolol succinate was 10-70 μg?mL-1( r=0.999 8) . Conclusion The releasing rate of metoprolol succinate sustained-release tablet prepared in optimum condition can meet the requirement. This preparation technology is simple, the assay method is rapid, sensitive and reproducible.
4.Status quo and difficulties of pharmaceutical advertisement supervision:Based on monitoring results of illegal pharmaceutical advertisements
Chinese Journal of Health Policy 2015;(4):24-30
Objective:To provide some suggestions for improving the pharmaceutical advertisement supervision system and standardizing the pharmaceutical advertisement market. Methods: Literature reviews, statistical analysis and interviews were adopted to study the status quo and difficulties of pharmaceutical advertisement supervision and pharmaceutical advertisement trends. Results:The top-level design of pharmaceutical advertisements supervision sys-tem has two defects:the separation between approval and penalty and the obstacles to cooperation at all levels of the drug administration. The worsening status quo of illegal drug advertising has elicited concern from scholars and regu-lators. However, there are still some difficulties in the supervision of drug advertisers, advertising agents, and pub-lishers. Conclusion:It is suggested that the drug advertising regulation system should be perfected by strengthening information supervision, establishing a coordination mechanism and consolidating self-discipline consciousness. Addi-tionally, laws and regulations should be promptly revised as an essential way to improve the effects of supervision.
5.Investigation on nutritional status and blood glucose control level in elderly patients with type 2 diabetes
Chinese Journal of Geriatrics 2015;34(2):202-206
Objective To investigate the nutritional status and glycemic control level in elderly patients with type 2 diabetes in urban community of Yangpu district in Shanghai.Methods The 24-hour dietary recall method for 3 consecutive days was used to investigate the dietary nutrients intake in 400 patients with type 2 diabetes.Results The ratio of patients with blood glucose level less than 6.1mmol/L was 23.3% (93/400).The energy intake in patients with type 2 diabetes was low,and only reached 62.81% of the recommended standard of energy intake for adults.The energy ratio of three diet nutrients (protein,fat and carbohydrate) were 14.41%,33.93%,51.66% respectively,which showed that the energy ratio of fat was relatively high.The energy ratio of breakfast,lunch and supper dinner were 23.37%,38.05% and 38.57% respectively.The average intake of vitamin E,iron,niacin,manganese,phosphorus and cholesterol in elderly patients was more than the recommended standard of adult diet nutrients,and reached 149.6%,138.1%,137.1%,132.5%,127.5% and 122.0% of the recommended standard respectively.But the average intakes of protein,fat,carbohydrate,dietary fiber,calcium,zinc,copper,magnesium,potassium,vitamin A,vitamin B1,vitamin B2 and vitamin C in elderly patients were lower than the recommended standard,and reached 77.9%,90.3%,57.1%,50.7%,49.3%,81.4%,75.7%,75.7%,77.5%,77.0%,55.1%,58.1% and 67.6% of the recommended standard respectively.Conclusions The status of dietary nutrients intake in elderly patients with type 2 diabetes in Yangpu district of Shanghai is unreasonable,the intakes of dietary fiber,calcium,vitamin B1,vitamin B2 etc.were insufficient,and reasonable diet instruction should be provided for the elderly patients.
6.Corticosteroids treatment in acute respiratory distress syndrome
Chinese Pediatric Emergency Medicine 2014;21(12):756-759
The presence and persistence of systemic and lung inflammation in children with acute respiratory distress syndrome (ARDS) is the basis for the use of corticosteroids as a therapeutic agent.The trial of ARDS treated with high-dose short-course corticosteroids showed no benefit,even increase motality.At present,the results of randomized controlled trial and meta-analysis suggested that low-dose and replacement-dose methylprednisolone [1-2 mg/(kg· d)] or equivalent types of corticosteroids may decrease the fatality rate,reduce staying days in ICU and the duration of mechanical ventilation.Use of corticosteroids for ARDS in children is still lack of multicenter randomized controlled trial.

8.Premium Approaches for Private Brand of Chain Drugstores
China Pharmacy 2005;0(13):-
OBJECTIVE: To provide references for Chinese drugstores to carry out private brand strategy. METHODS: The problems existing in the practice of private brand in Chinese drugstores were analyzed,and the basic conditions and effective premium approaches for private brand of pharmaceutical chain store were studied through a detailed analysis of consumer’s psychology and action. RESULTS & CONCLUSIONS: The problems existing in the practice of private brand in Chinese drugstores included the non-guaranteed quality assurance ability results from low price marketing and enterprise’s lack of cohesiveness results from enforcement on salesman to recommend products for customers etc. The main conditions to promote premium on private brand were to possess a consummate quality assurance system for products and services. The main approaches toward premium are to construct product line with drug brand image as foundation and to optimize the organization mode of the private brand management.
9.The Expression of Aquaporin-2,3,4 in Rats' Endolymphatic Sac and Kidney
Journal of Audiology and Speech Pathology 2004;0(05):-
Objective To confirm the expression of Aquaporin2,3,4(AQP2,3,4,water channel protein) in rats'endolymphatic sacs(ES)and kidneys and to investigate and to compare the effects of anti-diuretic hormone(AVP) and DDAVP([deamino-Cys1,D-Arg8]-Vasopressin,V2-receptor agonist)on the expression of AQP2 in rats' ESs and kidneys.Methods 30 healthy Swards white rats were divided into the negative control,AVP group and dDAVP group respectively.The animals were cardiacally perfused.The temporal bones and kidneys were taken out and sectioned by means of the paraffin-embedded technique.The sections of ESs were labeled with fluorescent antibody by immunohistochemical method,and the kidneys' with avidin-biotin-peroxidase complex method(ABC).The expressions of AQP-2 were confirmed in the ESs of the rats while the different effects of the AVP and DDAVP on the ESs and the kidneys were observed.The slides used were analyzed by the image-analyzer and the subsequent data were statistically studied.Results In the cytomembrane and cytoplasm of ESs' epithelia,the constant and clear fluorescent reaction could be observed in the normal control group with the first antibody of AQP2.Significant feeble fluorescent reaction of the first antibody of AQP-2 was revealed in AVP group and DDAVP group.In comparison with the control group,significant stain was found in AVP group and DDAVP group.Noted were also lower gray(P
