OBJECTIVE:To observe the efficacy and safety of eprosartan in the treatment of hypertensive patients with coro-nary heart disease. METHODS:160 hypertensive patients with coronary heart disease randomly divided into observation group and control group. All patients were given aspirin,nitroglycerin,low molecular weight heparin,statins and other conventional treat-ment;control group was additioanlly given 50 mg Losartan potassium tablet,orally,once a day. Observation group was additional-ly given 600 mg Eprosartan tablet,orally,once a day. The treatment course for both groups was 6 months. Clinical efficacy,sit-ting systolic blood pressure and diastolic blood pressure,alanine aminotransferase(ALT),aspartate aminotransferase(AST),urea (UREA),creatinine(Cr),uric acid(UA),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol (LDL-C),the Mini-Mental status (MMSE) scale and activities of daily living (ADL) scale scores before and after treatment and incidence of adverse reactions in 2 groups were observed. RESULTS:There was no signifi-cant difference in the total effective rate between 2 groups(P>0.05). After treatment,the sitting systolic blood pressure and diastol-ic blood pressure,MMSE and ADL scale scores in 2 groups were significantly lower than before,and sitting systolic blood pres-sure in observation group was lower than control group,the differences were statistically significant(P<0.05),and there were no significant differences in sitting diastolic blood pressure,MMSE and ADL scale scores between 2 groups(P>0.05),and no signifi-cant differences in ALT,AST,UREA,Cr,UA,TC,TG,HDL-C and LDL-C between 2 groups before and after treatment(P>0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Eprosartan can effectively reduce sitting systol-ic blood pressure in hypertensive patients with coronary heart disease,and improve cognitive function,with good safety.

OBJECTIVE:To study the effects and mechanism of propranolol on the myocardial abnormal electrophysiology sta-tion in diabetic model rats. METHODS:SD rats were randomly divided into normal control(normal saline)group,diabetic(nor-mal saline)group,PD98059(ERK inhibitor,10 mg/kg)group and propranolol low-dose,medium-dose and high-dose(1,20,50 mg/kg)groups,with 8 rats in each group. Except for normal control group,rats were given alloxan(20 mg/kg)intravenously via tail vein to induce diabetic model. They were given relevant medicine intragastrically,once a day,for consecutive 42 days. The car-diac index,electrocardiogram and action potential durations (APD) of rats were analyzed;the expression of TNF-α,IL-2,IL-6 and IL-10 protein in serum were detected,and the expression of Ras,Raf,ERK kinase(MEK)and ERK1/2 in myocardial tissue were detected. RESULTS:Compared with normal control group,cardiac index increased in diabetes group;heart rate decreased;QT interval and APD were prolonged;the relative expression of TNF-α,IL-2,IL-6,IL-10,Ras,Raf,MEK and ERK1/2 protein increased (P<0.01). Compared with diabetes group,cardiac index decreased in propranolol medium-dose and high-dose groups and PD98059 group,heart rate increased,QT interval and APD were shortened;the relative expression of TNF-α,IL-2,IL-6, IL-10,Ras,Raf,MEK and ERK1/2 protein decreased(P<0.05 or P<0.01). CONCLUSIONS:Propranolol can improve myocar-dial abnormal electrophysiology station of diabetic model rats by down-regulating inflammatory reactions in serum and inhibiting the activation of MEK/ERK signaling pathway.

OBJECTIVETo investigate the relationship between degree of abnormal deeper lateral femoral notch between anterior cruciate ligament tear.

METHODSThe radiograph and MRI image material of 16 patients with anterior cruciate ligament injury from January 2013 to November 2013 were reviewed including 14 males and 2 females with an average age of 28.3 years old ranging from 18 to 52 years. Eleven cases was on right side and 5 on left. Survey tool of PASC imaging system was used to measure the depth of lateral femoral notch in patients with abnormal indicated by lateral X-ray view or sagittal view of MRI in knee joint,while clinical data,physical examination,image material in arthroscopy of these patients were retrospective researched.

RESULTSFour patients had an abnormal lateral femoral notch with the depth of 2 mm on lateral X-ray and sagittal MRI, while positive anterior drawer sign and Lachman test as well as anterior cruciate ligament tears on MRI, and completed tears were comfirmed on the operation of arthroscopy. Two patients without abnomal lateral femoral notch on lateral view of X-ray while with the depth of 1 mm on sagittal view of MRI were also coupled with positive anterior drawer sign and Lachman test as well as anterior cruciate ligament tears on MRI, and one of them were comfirmed completed anterior cruciate ligament tears on the arthroscopy operation and completed tear could not comfirmed on another one because of disagreed with arthroscopy operation.

CONCLUSIONThere appears to be an association between abnormal lateral femoral notch on lateral view of knee with anterior cruciate ligament tears. An abnormal deeper lateral femoral notch is an indirect evidence for anterior cruciate ligament tears.

OBJECTIVETo observe the inhibitory effect of gefitineb on the proliferation and its inducing effect on the apoptosis of mouse I-10 Leydig testicular cancer cells in vitro.

METHODSWe treated I-10 Leydig testicular cancer cells of mice with gefitineb at 0, 1.25, 2.5, 5, 10, 20, and 40 µmol/L. Then we determined the inhibitory effect of gefitineb on the growth of the cells by MTT, detected their early and late apoptosis by Annexin V-FITC/propidium iodide double staining and Hoechst 33258 nuclear staining, respectively, and observed the expressions of apoptosis-related proteins Bcl-2, Bax and caspase 3/9 by Western blot.

RESULTSCompared with the blank control group, gefitineb significantly inhibited the proliferation of the I-10 cells at 10 and 20 µmol/L (P < 0.05). The survival rate of the cells was (32.4 ± 2.8)% (P < 0.01) and their early and late apoptosis rates were (26.7 ± 4.2)% and (59.33 ± 10.2)% in the 40 µmol/L group, significantly different from those in the control (P < 0.05 and P <0.01). In comparison with the blank control group, gefitineb at 10, 20, and 40 µmol/L increased the expression of pro-apoptotic protein Bax by (41.9 ± 7.1), (60.1 ± 9.8), and (69.0 ± 11.3)% (all P < 0.05), decreased that of apoptosis-inhibitory protein Bcl-2 by (50.3 ± 8.9), (63.9 ± 6.9), and (88.7 ± 13.9)% (all P < 0.05), and elevated that of the cleft proteins caspase-3 by (69.0 ± 6.9)% (P < 0.05), (71.5 ± 8.1)% (P < 0.05), and (110.9 ± 14.2)% (P < 0.01) and caspase-9 by (51.8 ± 4.9), (54.7 ± 6.7), and (43.8 ± 11.8)% (all P < 0.05).

CONCLUSIONGefitineb can increase the cytotoxicity of I-10 Leydig testicular cancer cells of mice and induce their apoptosis via the mitochondria-mediated apoptosis signaling pathway.

Objective To investigate the iodine content of food in six provinces of China,to add the results of this survey to the food iodine content database,and to provide a scientific basis for iodine supplementation in different parts of China.Methods A total of 8 categories and 39 species common food produced locally in the six provinces of Fujian,Chongqing,Shandong,Anhui,Gansu and Jilin were collected.Samples of cereals,beans and other dry samples were crushed into powder; samples of fresh fruits and vegetables were washed and dried to constant weight,and crushed into powder; poultry,meat and fish samples were washed and then their edible parts were crushed into meat paste,bake dried to constant weight,and crushed into powder.Iodine content in the above-mentioned food was determined by catalytic spectrophotometry,and the wavelength was 405 nm.Data processing and statistical analysis were carried out by using SPSS 13.0 statistical software.The results of total iodine content of the various types of food were expressed as median(P50) and interquartile range(P25 and P75).Results The iodine content of the cereal in Fujian,Chongqing,Shandong,Anhui,Gansu and Jilin were 11.9,12.0,48.0,95.1,13.0and 3.1 μg/kg,respectively; of the potato were 53.9,26.3,74.9,43.7,76.8 and 38.5 μg/kg,respectively; of the meat and the eggs were 56.0,30.4,78.6,124.6,47.7 and 34.8 μg/kg,respectively; of the aquatic products were 319.3,144.7,186.6,241.3,155.4 and 213.3 μg/kg,respectively; of the vegetables were 166.6,145.1,131.7,218.0,205.4 and 98.1 μg/kg,respectively; of the fruits were 105.5,17.8,80.9,1.7,76.7 and 10.3 μg/kg,respectively; of the kelp and laver were 36.0 × 103,1292.0 × 103,2810.0 × 103,48.0 × 103,75.0 × 103 and 120.0 × 103 μg/kg,respectively; of the Chinese pickled vegetables were 640.4,4163.5,3073.7,2635.3,1540.9 and 492.0 μg/kg,respectively.ConclusionsThe iodine content of different types of food,and same kind of food from different provinces are different.The results are a complement to the 2004 Chinese food composition database.

OBJECTIVETo generate a comprehensive clinical profile of intrahepatic cholestasis of pregnancy (ICP) by systematically reviewing ICP cases managed in our hospital.

METHODSThe recorded clinical data, including diagnosis, complications, management, and maternal and infant outcomes, of nine ICP cases were collected retrospectively and reviewed systematically.

RESULTSSeven of the nine total ICP patients presented with pruritus. All nine of the ICP patients showed bile acid level beyond the normal range. ICP complications included gestational hypertension (n = 3), diabetes mellitus (DM, n = 1) and impaired glucose tolerance (IGT, n = 1), and pre-eclampsia (n = 1). The infant of one patient with severe ICP showed meconium-stained liquor. All nine of the ICP patients underwent surgical delivery, of which three were delivered preterm (between the 35th and 36th week of gestation). All mothers' total bile acids declined to normal levels after delivery, and all infants survived without complication.

CONCLUSIONICP does not increase the puerpera mortality rate and does not represent a poor prognosis for infants. Bile acid levels in the ICP patients, however, may be related to the extent of premature delivery time. While the standard drug treatment of ursodeoxycholic acid is suitable for most ICP cases, those with insufficient gestational age may benefit from adjuvant corticosteroid therapy to promote fetal lung maturation prior to preterm delivery. Severe ICP cases should be managed by inducing artificial labor or performing Caesarean section.
