OBJECTIVETo investigate the effect of Si' an Capsule combined Enalapril on hypertensive trough/peak ratio (T/P) and circadian rhythm of blood pressure in patients with essential hypertension (EH).

METHODSSixty patients with EH of stage II, III were randomly divided into two groups, the 30 patients in the treated group were treated with Si' an capsule combined Enalapril, and the 30 patients in the control group were treated with Enalapril alone. All patients were given 24-hour ambulatory blood pressure monitoring before and after 4 weeks treatment. T/P of systolic and diastolic blood pressure (SBP & DBP) of each group were calculated. Circadian rhythm of blood pressure was observed at the same time.

RESULTST/P of SBP and DBP in the treated group was 62.4 +/- 7.0% and 66.3 +/- 8.1% respectively, which was obviously higher than that in the control group, 53.3 +/- 6.7% and 60.1 +/- 7.2%, respectively (P < 0.05). The blood pressure circadian rhythm recovering rate in the treated group was 73.3% and in the control group 50%, the difference was insignificant.

CONCLUSIONThe combination therapy of Si' an capsule and Enalapril could lower the blood pressure smoothly and restore the circadian rhythm of blood pressure in EH patients.

Objective To study the application effect of day-parting appointment for elderly hypertensive contracted outpatients in community. Methods In May 2018 two groups (experiment and control) of 103 elderly hypertensive contracted outpatients, aged between 60 and 80 and looked after by the team of family doctors, who had been diagnosed with hypertension and with medication for at least one year were set up.The experimental group used self-made community hypertension visiting card for appointments, and the control group used the original way of treatment.Six months later, comparison was made in blood pressure control, the number of outpatients, the time consumed and the satisfaction between the two groups. Results It was found in comparison that the blood pressure standard-reaching rate of the experimental group was better than that of the control group (P < 0.05);outpatients′ visits and time consumed were less than those of the control group, the time used in the clinic room was longer than that in the control group; the differences in these aspects between the two groups were significant (P < 0.05);the satisfaction of the overall outpatient perception, attitude of family doctors, treatment technology, visits control, dosage, cost and safety of medication in the experimental group were better than in the control group; there were significant differences in these aspects between the two groups (P < 0.05). Conclusion Community day-parting appointment proves to be more convenient, more time-saving and safer for outpatients, greatly improving the medical quality and satisfaction for community outpatients.

OBJECTIVETo investigate the differentiation of bone marrow mesenchymal stem cells (BMSCs) and the effects of BMSCs on the proliferation of cirrhotic fat-storing cells (CFSC) and hepatocytes in vitro.

METHODSBMSCs and hepatocytes were isolated and harvested from the bone marrow and livers of rats. A co-culture system was set up by transwell inserts in which the two chambers were separated by a semipermeable membrane. BMSCs labeled with PKH26 were cultured with hepatocytes/CFSC in the co-culture system and also in a cell-cell direct contact culture system. Anti-albumin and anti-smooth muscle alpha-actin (alpha-SMA) antibodies were tested by using fluorescence immunocytochemistry. BMSCs and hepatocytes/CFSC cultured alone served as controls. The proliferation level of hepatocytes in the co-culture system was measured. CFSC were cultured with the conditional medium of BMSCs, and their quantities were measured microscopically.

RESULTSExpression of albumin was observed in the hepatocytes of the two culture systems after they were cultured for 72 h but the albumin levels were higher in the cell-cell direct contact culture system (P<0.01). As compared to the controls, the number of hepatocytes was larger in the co-culture system (P<0.01). No expression of alpha-SMA in CFSC was observed in either culture system. The proliferation of CFSC was inhibited by the conditional medium of BMSCs. The longer the time of the co-culturing the more significant was the CFSC growth suppression (P<0.01).

CONCLUSIONSBMSCs can be induced into hepatocytes by a local micro-environment formed by hepatocytes. BMSCs may promote proliferation of hepatocytes and inhibit proliferation of CFSC.

OBJECTIVETo evaluate the usefulness of serum alpha-fetoprotein (AFP) in clinical diagnosis and screening for hepatocellular carcinoma (HCC).

METHODSTotally 290 HCC patients, 48 liver cirrhosis patients, and 49 healthy subjects were enrolled in this study. Serum AFP analysis was performed to investigate the correlation between the serum AFP level in HCC and the clinical or biochemical parameters of the disease, which included the size and number of tumor and the TNM stage. Sensitivities and specificities of AFP in HCC prediction at different cut-off levels were determined.

RESULTSThe serum AFP level was significantly higher in HCC patients than in liver cirrhosis patients (P = 0.0274) and healthy subjects (P = 0.0001). Among 290 HCC patients, 95 patients (32.8%) were AFP-negative (AFP < 20 microg/L), 195 (67.2%) were AFP-positive (AFP > or =20 microg/L). Sensitivity and specificity of AFP at 20 microg/L cut-off was 67.2% and 29.2%, respectively, and the positive and negative predictive value was 85.2% and 12.8%, respectively. Sensitivity of AFP at 400 microg/L cut-off was only 42.8%. Serum AFP levels were significantly different among HCC with different tumor size (P = 0.0009), tumor number (P = 0.0001), and TNM stage [TNM I vs. TNM III-IV (P = 0.0001); TNM II vs. TNM III-IV (P = 0.0003)].

CONCLUSIONSIncreased serum AFP level is highly suggestive in HCC diagnosis. Combined with other imaging examinations, AFP level can be used for the screening of high risk population and for the follow-up of AFP-positive patients.

Derris eriocarpa, a traditional Chinese medicine belonging to the family of Leguminosae, is widely distributed mainly over Yunnan, Guangxi and Guizhou of China. Modern pharmacological researches on this herb showed that it had extensive bioactivities, such as promoting urination, removing dampness and cough and reducing inspissated mucus and other biological activities. The extensive studies on the chemical constituents of this plant have resulted in the isolation of triterpenoids, steroids, fatty acid and others, but the flavone compounds haven't reported before. In our further research on the ethyl acetate of this plant, nine flavone compounds were obtained by column chromatography on silica gel, Sephadex LH-20, semi-prep HPLC, polyamide column chromatography and recrystallization for separation and purification. The structures were determined on the basis of extensive spectroscopic analysis, including MS, NMR experiments and comparison with spectroscopic data in the literature, respectively, as diosmetin (1), 3, 3'-di-O-methylquercetin (2), afromosin (3), 6, 3'-dihydroxy-7, 4'-dimethoxyisoflavone (4), odoratin (5), 7, 3'-dihydroxy-8, 4'-dimethoxyisoflavone (6), 6, 4'-dihydroxy-7, 3'-dimethoxyisoflavone (7), 5, 7, 4'-trihydroxy-3, 3', 5'-trimethoxyflavone (8), and alpinumisoflavone (9). All these compounds were isolated from Derris eriocarpa How for the first time. And the in vitro assays showed that compound 2 possessed moderate inhibitory activity against human cancer cells K562 and HEL.

Objective To compare and analyze the sensitivity,specificity of 4 domestic ELISA kits for detection of hepatitis B virus (HBV) markers (HBsAg,anti-HBs,HBeAg,anti-HBe,and anti-HBc).Methods Five hundred and ninety four serum samples collected from patients with chronic hepatitis B and abnormal blood donors were detected for HBV markers and by 4 domestic ELISA kits.Samples with conflicting results by different diagnostic kits were retested.Samples with the HBsAg values close to the cut-off point were detected by Abbott HBsAg confirmation kit (Architect HBsAg confirm).Sensitivity of the kits was determined,using the national sensitivity reference panels for HBsAg,anti-HBs,HBeAg,anti-HBe and anti-HBc.Results The rates of sensitivity on 4 domestic kits for detection of HBsAg were 4 to 10 times lower,and on the 4 domestic kits for detection of anti-HBs,HBeAg,anti-HBc and anti-HBc were 4 to 16 times lower,as compared to Abbott Architect kits.In addition,the domestic HBV ELISA kits had some false positive results.The total coincidence rates of HBsAg,anti-HBs,HBeAg,anti-HBe,anti-HBc were 96.46%-98.15%,94.28%-98.15%,98.15%-99.49%,90.07%-96.30%,92.09%-96.80%,respectively.Conclusion Both sensitivity and specificity of the domestically produced HBV ELISA kits should be improved.

OBJECTIVETo understand the correlation between CD4+ cell count, HIV viral load (VL) and clinical characteristics among patients when HIV-1 was tested positive and initial AIDS diagnosis was made.

METHODS690 HIV-infected cases from Beijing Di-Tan Hospital were included and under a cross sectional study while SPSS statistical method was used.

RESULTSThe 690 HIV-infected cases would include 458 males and 232 females with age range from 2-72 years (mean age as 35.3). The modes of transmission showed that: homosexual contact taking up 17.5% while heterosexual was 16.7%. Most of the homosexual-infected ones lived in Beijing and most of them had bachelor or master's degrees. 19.4% of the transmission happened between heterosexual/bisexual couples, suggesting that HIV was transmitted through the "bridge population" while the rest were infected by contaminated blood/plasma. Many of the cases were identified when they lately visited the pre-operation surveillance point in the hospital. Serious immunodeficiency symptoms or signs were discovered as: CD4+ count < 50 cell/microl, serious opportunistic infections including pneumocystosis pulmonary, cerebral toxoplasmosis and cryptococcal meningitis. Higher frequencies of diseases seen were dermotosis, pneumonia, upper respiratory tract infection, hepatitis and digestive tract moniliasis.

CONCLUSIONBecause of the late identification of the disease, serious immuo-suppression situation often appeared, suggesting that there was an urgent need to improve STD/AIDS knowledge on those HIV (+) people so they might have an early access to accept medical care.

OBJECTIVETo study the hepatotoxicity effects in rats with different extract of Fructus Gardeniae.

METHODObserve the change of appearance, behavior and weight of rats through oral gavage daily for 3 d. Weigh the liver and calculate the liver index. Detect the ALT, AST and TBIL. Observe the liver tissue by optical microscope.

RESULTThe weight and index of liver were increased by 3.08 g x kg(-1) aqueous extract, 1.62 g x kg(-1) alcoholic extract and 0.28 g x kg(-1) geniposide, compared to those of the blank group (P < 0.005, P < 0.001) and the activities of ALT, AST and the content of TBIL were also increased, compared to those of the blank group (P < 0.05, P < 0.001). The liver cells were obviously swell, necrotic and changed with inflammatory infiltrate.

CONCLUSIONAqueous extract, alcoholic extract and geniposide displayed hepatotoxicity, and the geniposide which was the main substance of the Fructus Gardeniae might be mainly responsible for the hepatotoxicity.

OBJECTIVETo evaluate the kinesis of cellular immunity in adults who were vaccinated with yeast recombinant hepatitis B(rHB) vaccine and the correlation between cellular and humoral immune responses induced by the vaccine.

METHODSEight adults were vaccinated with rHB vaccine according to 0, 1,2 month schedule. The peripheral blood mononuclear cells(PBMCs) were collected at the 3, 8, 21, 34 and 65 days after the first dose. The high purity of CD4+ and CD8+ T cells obtained by sorting from PBMCs were restimulated with recombinant hepatitis B surface antigens (rHBsAg) or peptides. The spot forming cell (SFC) of IFN-gamma, IL-2 and IL-4 of CD4+ and CD8+ T cells were detected by enzyme-linked immunospot (ELISPOT).

RESULTSThe characteristics of IFN-gamma, IL-2 and IL-4 of CD4+ and CD8+ T cells appeared different after immunization with rHB vaccine. IFN-gamma of CD8+ and CD4+ T cells could be detected early with stable SFC, while the IL-2 and IL-4 of CD4+ T cells appeared late but increased after the second and third dose of vaccination. The positive rate of IL-4 of CD4+ T cells were significantly correlated with the positive rate of anti-HBs, while the SFCs of IL-4 and IL-2 of CD4+ T cells were also significantly related to the titers of anti-FIBs.

CONCLUSIONIFN-gamma could be detected early after rHB vaccination in adults, and the positive rates of IL-4 and IL-2 were correlated with that of anti-HBs.
