Objective To put forward suggestions for improving the writing standards of package inserts of Chinese patent drug in China. Methods Totally 84 package inserts of Chinese patent drug were chosen randomly. The labeled items in them would be investigated and analyzed according to legal documents in China. Results The rate of complete labeled items was 0%. Meanwhile, many problems existed in the items which affected medication safety seriously. In addition, there were defects in expression of the content, revision of package inserts of Chinese patent drug and so on. Conclusion It is urgent to improve the writing standards and the completeness of the labeled items as well as the scientificalness on the expressions of package inserts of Chinese patent drug.

Diabetic retinopathy (DR) is one of the most significant microvascular complications of diabetes,and its incidence increases with the prolongation of DM;meanwhile,it can lead to severe vision loss.Recently,the pathogenesis of DR has been one of the focuses both at home and abroad,but the basic mechanisms are not fully elucidated.More and more scholars believe that DR may be a chronic and low degree of inflammatory response.Moreover,it is well established that microglia is a monocyte-macrophage,with antigen-presenting function.Especially in the retina,as microglia is activated,followed by the release of a large number of inflammatory factors,microglia involves in DR inflammatory response.Understanding the activation mechanism of microglia can provide a new perspective for the prevention and treatment of DR.Therefore,recent advances in activation of microglia in diabetic retinopathy and its intervention mechanism will be reviewed in the article.

TORCH infection during pregnancy is a group of infectious diseases resulting from viruses and other microorganisms. According to the past over 20-year experiences in serum screening in China, several infections which should be performed in the first trimester, or even much earlier in pregnant period, are hepatitis B, syphilis, HIV, and these three infections are confirmed to be harmful to the fetus or infants and also diagnostic methods and treatment are available. Screening for rubella should be better performed before conception and no specific management is required with IgM+, while immunization is recommended before pregnancy with IgM-. Screenings for cytomegalovirus, toxoplasmosis and herpes virus are not recommended. Scnography is warranted if fetal abnormalities were resulted from the above infections and amniocentesis or cordocentesis might be required for further investigations.

As one of the serious complications of diabetes, diabetic retinopathy( DR) has become a main eye disease which causes blindness. The occurrence and development of DR is related to many factors. The pathogenesis is complicated, and the mechanism has not been clear. Early data suggest that the occurrence and development of DR has relations with many factors such as blood sugar level, diabetes duration and the environment. Among the factors, mitochondrial dysfunction and oxidative stress is the important mechanisms of DR and has become research focus in recent years. Consequences of mitochondrial dysfunction within cells include elevation of the rate of reactive oxygen species( ROS) production due to damage of electron transport chain proteins, mitochondrial DNA ( mtDNA ) damage, and loss of metabolic capacity. Clear understanding on the mechanism of mitochondrial functional change under high sugar level and oxidative stress response in the occurrence and development of DR is of great significance on prevention and cure of DR. ln this article, the development of mitochondrial metabolism and oxidative stress of DR is reviewed.

Objective To explore the change of occludin mRNA in the lung tissue under hyperoxia induced lung injury condition and their regulation of platelet-derived growth factor B(PDGFB).Methods Three hundred and twenty newborn rats were divided into 4 groups accor-ding to different oxygen concentrations(FiO2):experimental group 1(FiO2=800 mL/L),experimental group 2 (FiO2=600 mL/L),experimental group 3(FiO2=400 mL/L) and room-air control group(FiO2=210 mL/L).Rats were killed at 1st,3rd,5th,7th and 14th day respectively during the experiment,the expression of occludin was examined by reverse transcription polymerase chain reaction(RT-PCR) method.The expression of PDGFB in the lung tissue was also observed by immunohistochemistry.SPSS 11.5 software was used to analyze the data.Results The expressions of PDGFB in the lung tissue in experimental group 1 and experimental group 2 were lower than those of the control group at 1th day(Pa

we examined the serum copper level in 125 pregnant women (83) normal pregnant women of 28～40 weeks of pregnancy; 12 patients with se-vere edema-proteinurine-hyperterision syndromeduring 37～40 weeks of pregnancy; 30 patientswith prolonged pregnancy) and compared it withurine E/C value and Apgar score in order to deter-mine the reliability of serum copper value in diag-nosing placental insufficiency. The results con-firmed that the serum copper value was increasingwith the growth of weeks of pregnancy, but it wasdecreasing after the fortieth week of pregnancy.Comparison of the serum copper value with theurine E/C value showed that when the E/C or = 10. And when the Apgar score7. These results indicatethat the serum copper value can serve as an indexof placental function in the third trimester of preg-nancy.

Objective To explore the role of oxidative stress in the initiation and development of experimental diabetic nephropathy.Methods Levels of MDA and the total SOD activity were tested in the whole kidney at 1 month,3 months and 6 months of experimental rat diabetes induced by streptozotocin.The pathological changes of diabetic rats were examined by light microscopy.Results The MDA level increased significantly in the diabetic group as compared to control group at all time intervals(2.16?0.57 vs 1.18?0.18,P

AIM: To establish the quality control for Lidanzhitong Tablet (Radix Paeoniae Rubra,Fructus Aurantii,Rhizoma Corydalis,etc.). METHODS:Radix Paeoniae Rubra, Fructus Aurantii and Rhizoma Corydalis were identified by TLC, and the content of paeoniflorin in Radix Paeoniae Rubra was determined by HPLC. RESULTS: Paeoniflorin showed a good linear relationship at a range of 0.597-4.997 ?g, r=0.999 9. The average recovery was 99.06%, and RSD was 3.4%. CONCLUSION: The method is accurate and reliable, and can be used to control the quality of this preparation effectively。
