AIM: To observe the changes of transient receptor potential channel 5 (TRPC5) in vascular smooth muscle cells ( VSMCs) of apolipoprotein E-knockout ( ApoE-/-) mice and the effect of atorvastatin interference, and to investigate the mechanism of atorvastatin therapy.METHODS:Male ApoE-/-mice at 6 weeks of age were used to establish the atherosclerosis model by feeding with hyperlipidic diet.The mice were randomly divided into model group and atorvastatin group.The mice in atorvastatin group were lavaged with atorvastatin at 20 mg· kg-1 · d-1 , while the mice in model group received normal saline.The healthy C57BL/6J mice with the same age and the same genetic background, feeding with ordinary food, served as control group.At the time points of 14 and 24 weeks, the mice were sacrificed.The serum was collected for detecting the lipid levels.The aortic roots of the heart were taken to make paraffin sections with HE staining for measuring and comparing the relative atherosclerotic plaque area in each section.The expression of TRPC5 in VSMCs was examined with immunohistochemical staining.The mRNA levels of TRPC5 in the serum and the thoracoabdom-inal aorta were measured by real-time PCR.RESULTS: Compared with model group, blood lipids in atorvastatin group were significantly decreased, and the formation of plaque under aorta intima also decreased.The protein expression of TR-PC5 in atorvastatin group decreased significantly compared with model group.Compared with 20-week model group, TRPC5 in 30-week model group showed increasing tendency, but has no statistical significance.Compared with 20-week atorvasta-tin group, TRPC5 of 30-week atorvastatin group declined.CONCLUSION: Atorvastatin suppresses TRPC5 expression, thus attenuating atherosclerotic development in ApoE-/-mice.

Patch tests were performed in 215 cases with contact dermatitis and 59 cases with noncontact dermatitis who visited the clinic of Xili Hospital, Shenzhen.Results showed that top four allergen for them were 0.1% Merthiolate, 5% nickel sulfate, 7% aromatic compounds and 1% formaldehyde in sequence.There was significant difference in occurrence of dermatitis at the hands, trunk, extremities,face, and periumbilicus caused by these four kinds of allergen (P <0.01 ), with 0.1% Merthiolate mainly causing dermatitis at the face, hands, trunk and extremities, 5% nickel sulfate causing dermatitis at the periumbilicus, trunk and extremities, 7% aromatic compounds causing dermatitis at the hands, trunk,extremities and face, whereas 1% formaldehyde mainly causing facial dermatitis.Concentration of pentyl acetate and rosin spirit used for patch tests should be 20 % and 25 %, respectively.

OBJECTIVE:To understand the proportion of university faculty suffering from hypertension,and the regularity,ratio-nality and affordability of antihypertensive drugs under closed medical environment. METHODS:Empirical research and research methods were adopted to collect indicators during 2011-2014,such as average daily wage in Wuhan,the total number of staff in Wuhan University,the number of staff with hypertension,antihypertensive drugs amount/DDDs ranking ratio,affordability ratio,relative av-erage affordability, etc. The rationality and affordability of antihypertensive drug prices were evaluated. RESULTS:During 2011-2014,the prevalence rate of hypertension in the staff were about 23%,and the proportion increased year by year;the annual in-crease of antihypertensive drug amount was larger than that of the number of patients;the type of antihypertensive drugs with affordabil-ity ratio>1 in 4 years was ARB varieties,and affordability ratio of other drugs was less than 1. CONCLUSIONS:More than half of drugs is high in price,that result in heavy burden of patients receiving ARB;on the whole,antihypertensive drugs are affordable of the teaching staff of Wuhan University.

Objective: To compare the contents of saikosaponin a, d and total flavonoids in different parts of Hollow bupleurum to provide reference for the clinical use of medicinal parts.Methods: The determination was performed on a SHIMADZU Inertsil C18(250 mm×4.6 mm,5 μm)column.The mobile phase consisted of acetonitrile and water with the ratio of 40∶60, and the flow rate was 1.0 ml·min-1.The detection wavelength was 210nm, the column temperature was 40℃, and the injection volume was 10 μl.A colorimetric method was used to detect total flavonoids with the detection wavelength of 500 nm.Results: The calibration curve of Saikosaponin a, d and total flavonoids showed a good linear relationship respectively over the range of 0.21-1.26 mg·ml-1(r=0.999 6),0.25-1.51 mg·ml-1(r=0.9997) and 4.00-25.00 μg·ml-1(r=0.999 6).The average recovery was 99.27%(RSD=2.15%, n=6),99.4%(RSD=2.14%,n=6)and 99.03%(RSD=1.34%,n=6), respectively.The content of saikosaponin a and d respectively was 0.31% and 0.50% in the root, while that in the other parts was low.The content of total flavonoids was as high as 8.48% in flowers, and that in leaves, stem and root reduced in turn.Conclusion: The aerial parts of Hollow bupleurum are rich in flavonoids, and the content of saikosaponin in root is higher, therefore, the whole plant with root is more reasonable in the clinical use.

Objective To investigate the clinical value of docetaxel combined with psychological intervention in elderly patients with advanced non-small cell lung cancer. Methods the control group received docetaxel chemotherapy, and the study group received psychological intervention on the basis of docetaxel chemotherapy. The efficacy, adverse reactions and adverse emotions of two groups of elderly patients with advanced non-small cell lung cancer were recorded. Results the total efficiency was up to 54.17%, only 41.67% of the control group (P<0.05); toxic and side effects in the research group alopecia, gastrointestinal reaction, rash was significantly lower than the control group did not received psychological intervention (P<0.05); the control group after treatment SAS, SDS score increased than before more than the study group (P<0.05). Conclusion On the basis of docetaxel in the treatment of elderly patients with advanced non-small cell lung cancer, the use of appropriate psychological intervention measures can significantly alleviate the negative emotions, and have positive significance to ensure the effectiveness and safety of chemotherapy.

Objective To observe the antioxidative capability and the mRNA expression of sodium pump αl-subunit in kidney of hypothyroid rats by iodine deficiency and illuminate the pathogenesis of kidney damage.Methods Wistar rats were randomly divided into two groups as control group (NT) and hypothyroid group (HT).The rats were all fed with low-iodine diet derived from an endemic goiter area and drank deionized water containing different potassium iodide to duplicate hypothyriod animal models.We determined the morphometric parameters of kidney by routine histology method.The contents of malondialdehyde and free radical scavengers (GSH-PX and SOD) in kid-ney,as well as the activity of Na~+-K~+ ATPase were measured in two groups.The mRNA expression of sodium pump α1 subunit was determined by reverse transcription-polymerase chain reaction.Results Compared with that in the control group,in hypothyroid group (1) serum free T3,free T4,total T3 and total T4 were markedly lower.(2) mean glomerular area and volum diminished markedly.(3)the content of MDA and activity of PGx increased markedly,but the activity of SOD decreased significantly,as well as the one of Na~+-K~+-ATPase.(4)the mRNA expression level of sodium pump α1 subunit was lower.Conclusion In a hypothyroid state,the decrease of antiox-idative capability of kidney resulted in lipid peroxidative damage,atrophy of kidney,decreased activity of Na~+-K~+ -ATPase and degression of sodium pump α1 subunit mRNA expression.
