Aim To investigate the combined pharmacokinetic-pharmacodynamic(PK-PD) model of irbesartan in healthy Chinese male volunteers. Methods Eighteen healthy male volunteers received 300 mg irbesartan tablet orally. The plasma drug concentration (C_p) was determined by HPLC and pharmacologic effects, including SBP, DBP and HR, were measured simultaneously. The pharmakinetic and PK-PD model parameters were calculated. Results The pharmacokinetic profiles were best fitted a two-compartment open model. There was a hysteresis loop between effects and plasma concentrations. The relationship between effects and effect compartment concentrations of drugs could be represented by the Sigmoid-E_ max model. Conclusion We successfully eatablished the PK-PD model of irbesartan in healthy male volunteers. These findings may provide a more rational basis for patient-specific dosage individualization.

Objective To evaluate CT diagnositic value for endo-bronchial tuberculosis(TB).Methods CT findings of 14 cases with endo-bronchial TB proved by fibro-bronscopy(FOB) were studied retrospectively.Results The bronchiarctia was seen at lobar bronchas or segmental bronchas in all 14 cases.Of them,in 6 cases,the bronchiarctia appeared as conic stenosis accompanied with atelactasis and a large amount of plearal effusions,in 8 cases,the bronchial walls were thichened including centrality stenosis in 3 cases,unilateral stenosis in 5 cases and accompanied with polyus in 3 cases.No hilar mass and opposite "S" sign were found.The "bronchial air sign" was showed at the area of ateectasis.9 cases were accompanied by active pulmonary TB(64.3%).Conclusion CT is of important value in diagnosing endo-bronchial TB and differentiating the tumorous or no-tumorous bronchiarctia,while the diagnonsis at early stage of this disease has to depend on FOB.

Objective To study the effects of Rhodiolae Crenulatae Radix ET Rhizoma extracts on sexual behavior of male mice.Methods 50 healthy male mice were randomly divided into the low dose, middle dose and the high dose Rhodiola group, theNanbao capsules group and the normal control group, 10 mice per group. The low dose, middle dose and high dose group were drenched with 0.05, 0.20 and 0.80 g/kg Rhodiola diluent respectively. TheNanbao capsules group mice were drenched with 2.00 g/kg turbid liquid. The normal control group were drenched with saline in the same volume. Liquid is drenched two times each day for 21 days. After 21 days, 50 female mice were matched with to the ratio of 1:1. The number of free movement and swimming test were observed before execution. After the execution, the organ indexes were calculated, and then the contents of SOD and MDA in the testis and liver were measured.Results Compared with the normal control group, capturing latency period of low dose group and middle dose group (20.88 ± 19.94 s, 35.40 ± 22.02 svs.78.11 ± 43.33 s) significantly decreased (P<0.05 orP<0.01). Testicular coefficient of the middle dose group (0.72% ± 0.10 %vs. 0.64% ± 0.08%) was significantly increased (P<0.05); the content of SOD in testicular of the middle dose group, the high dose groups and theNanbao capsules group (152.71 ± 38.10 U/mg, 122.32 ± 52.76 U/mg, 94.38 ± 22.20 U/mgvs. 25.30 ± 14.21 U/mg) increased (P<0.01); the content of SOD in liver of the middle dose group and theNanbaocapsules group (77.71 ± 26.35 U/mg, 74.10 ± 26.04 U/mgvs. 57.92 ± 17.17 U/mg) significantly increased (P<0.05).Conclusion Rhodiola extract can improve the ability of sexual behavior of male mice, and improve the antioxidant capacity of testis and liver.

Objective To observe the effects of transdermal acupoint electric stimulation(TEAS)assisting sodium nitroprus-side induced controlled hypotension on serum glucose (Glu),angiotensin Ⅱ (ATⅡ)and superoxide dismutase (SOD),and to inves-tigate the protective effect of TEAS under controlled hypotension anesthesia.Methods 60 cases undergoing elective endoscopy si-nus surgery by adopting sodium nitroprusside induced controlled hypotension under general anaesthesia maintained the mean arterial pressure(MAP)in 50-60 mm Hg and were randomly and equally divided into two groups.The group Ⅰ conducted TEAS,while the group Ⅱ did not conduct TEAS.The controlled hypotension time and surgery time were recorded in the two groups;Glu and ATⅡ values were detected before anesthesia (T0 ),30 min after hypotension (T1 ),hypotension stopping(T2 );SOD was detected at T0 ,T2 ,30 min after hypotension(T3 ).Results The operation time and controlled hypotension continuous time had no statistically significant difference between the two groups(P >0.05).The Glu value in the group Ⅰ had no statistically significant difference a-mong the 3 time points,while which at T1 ,T2 was higher than that at T0 in the group Ⅱ(P <0.05),and which at T1 ,T2 in the group Ⅱ was higher than that in the group Ⅰ (P <0.05);the ATⅡ value at T1 was higher than that at T0 in the group Ⅰ (P <0.05),while which at T1 ,T2 was higher than that at T0 in the group Ⅱ(P >0.05),which at T1 ,T2 in the group Ⅱwas higher than that in the group Ⅰ (P <0.05);the SOD value at T2 was lower than that at T0 in the group Ⅰ,which at T2 ,T3 in the group Ⅱwas lower than that in the group Ⅰ(P <0.05).Conclusion TEAS assisting sodium nitroprusside controlled hypotension can better in-hibit the stress response.

AIM: To quest the relationship bwteen BDNF and seizures. METHODS: BDNF and other correlative proteins in the hippocampus of audioepileptic rat (P77PMC) have been detected by immunohistochemistry at different stages of seizures including quiet stage, preconvulsive stage, convulsive stage and postconvulsive stage. Wistar rats were served as controls. RESULTS: At quiet stage, the BDNF in the hippocampus of P77PMC were less than that of control group and stepped up after stimulation, trkB in the hippocampus of P77PMC were high at every stages, but PY20 were increased only after stimulation. NPY in the hippocampus of P77PMC were in a low level before seizures. CONCLUSION: The endogenetic BDNF may alter the excitement of P77PMC by adjusting the expression of NPY in hippocampus and activating its receptor trkB.

Objective To explore the effect of glucose fluctuation on resistin. Methods The phorbol-12-myristate-13-acetate(PMA)-activated and differentiated U937 cells were exposed to experimental condition for 3 days, three groups of cells were formed, each one receiving the following fresh medium every 6 hours, respectively: (1) continuous 11.1 mmol/L glucose concentration medium (Con group), (2)continuous 22.2 mmol/L glucose concentration medium (CHG group), (3) alternating 11.1 mmol/L glucose concentration and 22. 2 mmol/L glucose concentration medium every 6 hours (IHG group). The supernatants of cell mediam at the last 6 hours were collected to test resistin concentration. Besides, 92 subjects were selected and classified into three groups according to the results of oral glucose tolerance test:normal glucose tolerance group ( NGT group, n =30), impaired glucose tolerance patients (IGT group, n =31) and newly diagnosed type 2 diabetes patients (T2DM group, n =31). Blood glucose and serum resistin levels were measured at 0 h and 1 h during oral glucose tolerance test ( OGTT) to compare the glucose fluctuation (△Glu1-0) and the change of serum resistin level (△lnRes1-0) among the three groups. Results Resistin concentration in the Con , CHG and IHG group was (73.62 ± 5.07)ng/L, (97.78 ±7.00)ng/L and(212.49 ± 28. 81 )ng/L respectively and in IHG group it was higher as compared with the other two groups (P<0.05). △Glu1-0 in NGT, IGT and T2DM group was(2.31 ±2.30)mmol/L,(5.70 ±2.08)mmol/L and (8.41 ±2.63)mmol/L respectively; △Glu1-0 increased gradually in all the three groups (P<0.05). Serum resistin level from 0 h to 1 h in the NGT group was 6.41 (1.52-15.76) μg/L to 6. 96( 1.52-22. 70) μg/L, in the IGT group 5.47( 1.49-24. 09)μg/L to 9. 12( 1.27-21.94)μg/L and in the T2DM group 5.77( 1.11-30.10) μg/L to 9. 27(1.02-48.15)μg/L In the IGT and T2DM group serum resistin level increased from 0 h to 1 h (P<0.05), but no difference was observed in the NGT group (P>0. 05).△lnRes1-0 in these 3 groups was (0.05 ± 0.05) μg/L, (0.25 ± 0.04) μg/L and (0.37 ± 0.03 )μg/L respectively and the change in the T2DM group was significant as compared with that in the NGT group,△lnRes1-0 was positively correlated with △Glu1-0 (r = 0.23, P = 0.02). Conclusion Glucose fluctuation induced monocyte/macrophage to secrete resistin, greater the glucose fluctuation, greater the change of amplitude of serum resistin.

OBJECTIVETo perform a comparative analysis of the reactivation rate of hepatitis B virus (HBV) infection and related risk factors after treatment of HBV-related hepatocellular carcinoma (HCC) by radiofrequency ablation (RFA) or hepatic resection.

METHODSWe retrospectively analyzed the HBV reactivation rate and related risk factors of a cohort of 218 patients treated for HBV-related HCC between August 2008 and August 2011; the study population consisted of 125 patients who received RFA and 93 patients who received hepatic resection. Comparisons were made using the unpaired Student's t-test for continuous variables and the x2-test and Fisher's exact test for categorical variables. Univariate and multivariate logistic regression analysis was used to assess risk factors.

RESULTSTwenty patients showed HBV reactivation following treatment, but the incidence was significantly lower in the RFA group than in the hepatic resection group (5.6% vs. 14.0%, 7/125 vs. 13/93, x2 = 4.492, P = 0.034). The univariate and multivariate analysis indicated that no antiviral therapy (OR = 11.7; 95% CI: 1.52-90.8, P = 0.018) and the treatment type (i.e. RFA or hepatic resection) (OR = 3.36; 95% CI: 1.26-8.97, P = 0.016) were significant risk factors of HBV reactivation. Subgroup analysis showed that the incidence of HBV reactivation was lower in patients who received antiviral therapy than in those who did not for both the RFA group and the hepatic resection group but the difference was not significant in the former group (1/68 vs. 19/150, x2=7.039, P = 0.008 and 0/33 vs. 7/92, x2 = 2.660, P = 0.188, respectively). However, the incidence of HBV reactivation in patients who did not receive antiviral therapy was higher than in those who did receive antiviral therapy in the hepatic resection group (12/58 vs. 1/35, x2 = 5.773, P = 0.027).

CONCLUSIONThe incidence of HBV reactivation was lower in patients who received RFA than in those who received hepatic resection to treat HBV-related HCC. Antiviral therapy prior to the hepatic resection treatment may be beneficial for reducing the incidence of HBV reactivation.

Objective:To understand the clinical research knowledge, attitude and practice of pediatrics residents in standardized residency training, and to provide scientific basis for improving their capability of clinical medical scientific research.Methods:A self-complied questionnaire survey including demographic information, knowledge and attitudes toward capability of medical scientific research as well as personal interview was conducted in 22 pediatric residents during the standardized residency training from April to July, 2017. Data were analyzed by (mean±standard deviation) and percentage for description, and qualitative data were analyzed by classification and induction. SPSS 18.0 was used to analyze the data.Results:Firstly, the total score of basic knowledge in clinical scientific research was (54.14±23.06), with the scores between 31 and 60 being the most. Secondly, all these residents believed that capability of clinical medical scientific research was very important for them and clinical research training was necessary for them during the standardized residency training. Thirdly, the residents had the scientific research practices but no article published during the standardized residency training. Fourthly, the residents hoped to improve their capability of clinical scientific research by various means during the training.Conclusion:It is indicated that basic knowledge on capability of clinical medical research is still insufficient in standardized residency training of pediatrics residents, so relevant measures should be taken to cultivate their capability of clinical scientific research.
