Comparison of efficacy，safety and economics of bid-winning and original Moxifloxacin hydrochloride tablets in the treatment of outpatient community-acquired pneumonia / 中国药房

OBJECTIVE To compare the efficacy， safety and economics of bid-winning and original Moxifloxacin hydrochloride tablets in the treatment of outpatient community-acquired pneumonia （CAP）. METHODS A retrospective cohort study was conducted to screen and include CAP outpatients during the period of January to December 2021 in Lianyungang First People’s Hospital. They were divided into generic drug group （1 058 cases） and bid-winning drug group （1 121 cases） according to the drug source. Two groups were respectively given original and bid-winning Moxifloxacin hydrochloride tablets， 0.4 g each time， once a day. The efficacy indexes （clinical effective rate， remission time， treatment course， revisiting rate） and safety indexes （allergy， nervous system symptoms， etc.） were compared between the two groups； and the influence factors of clinical treatment failure were analyzed with multi-factor modified Poisson regression model. The economic indicators of the two drugs [quantity， consumption sum， defined daily doses （DDDs）， defined daily dose cost （DDDc）， price ratio， replacement rate] were compared. RESULTS There were no significant differences in the clinical effective rate， treatment course， revisiting rate， the incidence of nervous system symptoms and Q-T interval prolongation between the two groups （P＞0.05）. The remission time of original drug group was significantly shorter than that of bid-winning drug group， and the incidence of total adverse drug reaction， allergy reaction， gastrointestinal symptom reaction and hyperglycemia were significantly lower than those in bid-winning drug group（P＜0.05）. Multivariate Poisson regression analysis showed that bid-winning drug did not increase the risk of clinical treatment failure in CAP outpatients [RR＝1.132， 95%CI （0.883， 1.542）， P＝0.327]. However， antibiotic exposure history， more than 2 items of abnormal clinical manifestations and auxiliary examination all increased the risk of clinical treatment failure （P＜0.05）. Compared with before the implementation of centralized volume-based procurement policy， the quantity and DDDs of Moxifloxacin hydrochloride tablets increased significantly， while the consumption sum decreased significantly， DDDc of bid-winning drug decreased significantly， the price ratio of it to original drug decreased to 0.117， and the replacement rate increased to 69.44% after the implementation of centralized volume- based procurement policy. CONCLUSIONS Compared with original drug， bid-winning Moxifloxacin hydrochloride tablet shows reliable efficacy and obvious price advantage in the treatment of outpatient CAP， but the incidence of adverse drug reactions is higher.

Tea consumption and cancer: a Mendelian randomization study / 中华流行病学杂志

Objective: A Mendelian randomization (MR) analysis was performed to assess the relationship between tea consumption and cancer. Methods: There were 100 639 participants with the information of gene sequencing of whole genome in the China Kadoorie Biobank. After excluding those with cancer at baseline survey, a total of 100 218 participants were included in this study. The baseline information about tea consumption were analyzed, including daily tea consumption or not, cups of daily tea consumption, and grams of daily tea consumption. We used the two-stage least square method to evaluate the associations between three tea consumption variables and incidence of cancer and some subtypes, including stomach cancer, liver and intrahepatic bile ducts cancer, colorectal cancer, tracheobronchial and lung cancer, and female breast cancer. Multivariable MR and analysis only among nondrinkers were used to control the impact of alcohol consumption. Sensitivity analyses were also performed, including inverse variance weighting, weighted median, and MR-Egger. Results: We used 54, 42, and 28 SNPs to construct non-weighted genetic risk scores as instrumental variables for daily tea consumption or not, cups of daily tea consumption, and grams of daily tea consumption, respectively. During an average of (11.4±3.0) years of follow-up, 6 886 cases of cancer were recorded. After adjusting for age, age2, sex, region, array type, and the first 12 genetic principal components, there were no significant associations of three tea consumption variables with the incidence of cancer and cancer subtypes. Compared with non-daily tea drinkers, the HR (95%CI) of daily tea drinkers for cancer and some subtypes, including stomach cancer, liver and intrahepatic bile ducts cancer, colorectal cancer, tracheobronchial and lung cancer, and female breast cancer, are respectively 0.99 (0.78-1.26), 1.17 (0.58-2.36), 0.86 (0.40-1.84), 0.85 (0.42-1.73), 1.39 (0.85-2.26) and 0.63 (0.28-1.38). After controlling the impact of alcohol consumption and performing multiple sensitivity analyses, the results were similar. Conclusion: There is no causal relationship between tea consumption and risk of cancer in population in China.

A descriptive analysis of hyperlipidemia in adult twins in China / 中华流行病学杂志

Objective: To describe the distribution characteristics of hyperlipidemia in adult twins in the Chinese National Twin Registry (CNTR) and explore the effect of genetic and environmental factors on hyperlipidemia. Methods: Twins recruited from the CNTR in 11 project areas across China were included in the study. A total of 69 130 (34 565 pairs) of adult twins with complete information on hyperlipidemia were selected for analysis. The random effect model was used to characterize the population and regional distribution of hyperlipidemia among twins. The concordance rates of hyperlipidemia were calculated in monozygotic twins (MZ) and dizygotic twins (DZ), respectively, to estimate the heritability. Results: The age of all participants was (34.2±12.4) years. This study's prevalence of hyperlipidemia was 1.3% (895/69 130). Twin pairs who were men, older, living in urban areas, married,had junior college degree or above, overweight, obese, insufficient physical activity, current smokers, ex-smokers, current drinkers, and ex-drinkers had a higher prevalence of hyperlipidemia (P<0.05). In within-pair analysis, the concordance rate of hyperlipidemia was 29.1% (118/405) in MZ and 18.1% (57/315) in DZ, and the difference was statistically significant (P<0.05). Stratified by gender, age, and region, the concordance rate of hyperlipidemia in MZ was still higher than that in DZ. Further, in within-same-sex twin pair analyses, the heritability of hyperlipidemia was 13.04% (95%CI: 2.61%-23.47%) in the northern group and 18.59% (95%CI: 4.43%-32.74%) in the female group, respectively. Conclusions: Adult twins were included in this study and were found to have a lower prevalence of hyperlipidemia than in the general population study, with population and regional differences. Genetic factors influence hyperlipidemia, but the genetic effect may vary with gender and area.

A descriptive analysis on hypertension in adult twins in China / 中华流行病学杂志

Objective: To describe the distribution characteristics of hypertension among adult twins in the Chinese National Twin Registry (CNTR) and to provide clues for exploring the role of genetic and environmental factors on hypertension. Methods: A total of 69 220 (34 610 pairs) of twins aged 18 and above with hypertension information were selected from CNTR registered from 2010 to 2018. Random effect models were used to describe the population and regional distribution of hypertension in twins. To estimate the heritability, the concordance rates of hypertension were calculated and compared between monozygotic twins (MZ) and dizygotic twins (DZ). Results: The age of all participants was (34.1±12.4) years. The overall self-reported prevalence of hypertension was 3.8%(2 610/69 220). Twin pairs who were older, living in urban areas, married, overweight or obese, current smokers or ex-smokers, and current drinkers or abstainers had a higher self-reported prevalence of hypertension (P<0.05). Analysis within the same-sex twin pairs found that the concordance rate of hypertension was 43.2% in MZ and 27.0% in DZ, and the difference was statistically significant (P<0.001). The heritability of hypertension was 22.1% (95%CI: 16.3%- 28.0%). Stratified by gender, age, and region, the concordance rate of hypertension in MZ was still higher than that in DZ. The heritability of hypertension was higher in female participants. Conclusions: There were differences in the distribution of hypertension among twins with different demographic and regional characteristics. It is indicated that genetic factors play a crucial role in hypertension in different genders, ages, and regions, while the magnitude of genetic effects may vary.

Establishment of a Patient-Derived T-Cell Acute Lymphoblastic Leukemia Xenograft Model in Novel Immunodeficient NCG Mice / 中国实验血液学杂志

OBJECTIVE@#The leukemia cells from patients with T-cell acute lymphoblastic leukemia (T-ALL) were inoculated into NCG mice to establish a stable human T-ALL leukemia animal model.@*METHODS@#Leukemia cells from bone marrow of newly diagnosed T-ALL patients were isolated, and the leukemia cells were inoculated into NCG mice via tail vein. The proportion of hCD45 positive cells in peripheral blood of the mice was detected regularly by flow cytometry, and the infiltration of leukemia cells in bone marrow, liver, spleen and other organs of the mice was detected by pathology and immunohistochemistry. After the first generation mice model was successfully established, the spleen cells from the first generation mice were inoculated into the second generation mice, and after the second generation mice model was successfully established, the spleen cells from the second generation mice were further inoculated into the third generation mice, and the growth of leukemia cells in peripheral blood of the mice in each group was monitored by regular flow cytometry to evaluate the stability of this T-ALL leukemia animal model.@*RESULTS@#On the 10th day after inoculation, hCD45+ leukemia cells could be successfully detected in the peripheral blood of the first generation mice, and the proportion of these cells was gradually increased. On average, the mice appeared listless 6 or 7 weeks after inoculation, and a large number of T lymphocyte leukemia cells were found in the peripheral blood and bone marrow smear of the mice. The spleen of the mice was obviously enlarged, and immunohistochemical examination showed that hCD3+ leukemia cells infiltrated into bone marrow, liver and spleen extensively. The second and third generation mice could stably develop leukemia, and the average survival time was 4-5 weeks.@*CONCLUSION@#Inoculating leukemia cells from bone marrow of patients with T-ALL into NCG mice via tail vein can successfully construct a patient-derived tumor xenografts (PDTX) model.

After adjustment for age and sex, no moderation effects of lifestyles, including current smoking, current drinking, physical activity, intake of vegetable and fruit, on the genetic variance of CHD were found (P>0.05), suggesting no significant interactions. Conclusion: There was no evidence suggesting statistically significant gene-lifestyle interaction on CHD in adult twins of China.

A descriptive analysis on coronary heart disease in adult twins in China / 中华流行病学杂志

Objective: To describe the distribution characteristics of coronary heart disease in adult twins recruited from Chinese Twin Registry (CNTR), and provide clues and evidence for the effect of genetic and environmental influences on coronary heart disease. Methods: By using the data of CNTR during 2010-2018, a total of 34 583 twin pairs aged ≥18 years who completed questionnaire survey and had related information were included in the current study to analyze the population and area distribution characteristics of coronary heart disease. Random effect models were used to compare the differences between groups. The concordane rate of coronary heart disease were calculated respectively in monozygotic (MZ) twin pairs and dizygotic (DZ) twin pairs to estimate the heritability. Results: The twin pairs included in this analysis were aged (34.2±12.4) years. The overall prevalence rate of coronary heart disease in twin pairs was 0.7%. Twin pairs who were women, older, obese and lived in northern China had higher prevalence of coronary heart disease (P<0.05). Intra-pair analysis in the same-sex twin pairs found that the concordane rate of coronary heart disease was higher in MZ twin pairs (25.3%) than in DZ twins (7.4%), and the difference was statistically significant (P<0.001). The overall heritability of coronary heart disease was 19.3% (95%CI: 11.8%-26.8%). Stratified by gender, age and area, the concordane rate was still higher in MZ twin pairs than in DZ pairs. Participants who were women, aged 18-30 years or ≥60 years and lived in northern China had a higher heritability of coronary heart disease. Conclusion: The distribution of coronary heart disease in twin pairs differed in populations and areas. The prevalence of coronary heart disease was affected by genetic factors, but the effect varied with age, gender and area.

OBJECTIVE@#To analyze the influenza vaccination trend of hospitalized elderly people (≥ 60 years old) in Beijing from 2013 to 2019.@*METHODS@#The influenza vaccination status and hospitalization information of elderly people were extracted from the Beijing Elderly Influenza Vaccination database (2013-2019) and the Beijing Urban Employee Basic Medical Insurance database (2013-2019), se-parately. The influenza vaccine coverage rates and annual percentage change were calculated to compare the vaccination trends of elderly people hospitalized due to different diseases. The subjects in 2018-2019 influenza season were divided into different groups according to demographic status, health conditions and hospitalization outcomes to describe and compare the distribution of influenza vaccination rates.@*RESULTS@#The influenza vaccine coverage rates among the elderly people hospitalized due to cardiovascular diseases, cerebrovascular diseases, respiratory diseases or diabetes mellitus were 14.6%, 13.4%, 13.4% and 11.8%, respectively. The influenza vaccination rate among those hospitalized for cardiovascular diseases remained the highest across six influenza seasons and those hospitalized for diabetes mellitus remained the lowest. The largest annual decline of influenza vaccine coverage rate was observed among the hospitalized elderly due to diabetes mellitus (-7.85%). The distribution of vaccinated population was significantly associated with age, gender, hospitalization outcome and comorbidities among the hospitalized elderly people with specific diseases in 2018-2019. Among the elderly people hospitalized due to four different diseases, the vaccination rate of the patients aged 70-79 years was higher than that of the other age groups and that of the patients aged 60-69 years was the lowest. Among the elderly people hospitalized due to respiratory diseases, the vaccination rate of men was higher than that of women, while the situation reversed among the elderly people hospitalized due to cardiovascular diseases and diabetes mellitus. Vaccination rates decreased among the older adults with poor hospitalization outcomes. Among the elderly people hospitalized due to diabetes mellitus, those with 0 comorbidity had the lowest vaccination rate (7.9%).@*CONCLUSION@#The trend of influenza vaccine coverage rates among the elderly people in Beijing from 2013 to 2019 was downward. We should pay more attention to influenza vaccination in elderly people with diabetes mellitus and aged 60-69 years, and carry out more research on the protective effects of influenza vaccine to promote influenza vaccine coverage among people with chronic diseases.

Analysis on related factors of myocardial fibrosis in patients with hypertrophic cardiomyopathy / 中华心血管病杂志

Objective: To investigate the related factors of myocardial fibrosis in patients with hypertrophic cardiomyopathy. Methods: Patients with hypertrophic cardiomyopathy, hospitalized in the First People's Hospital of Yunnan Province from January 2016 to May 2020, were included in this cross-sectional study. Patients were divided into delayed enhancement positive group (fibrosis group) and non-delayed enhancement group (non-fibrosis group). According to the maximum left ventricular end diastolic wall thickness (LVMWT), patients in the fibrosis group was further divided into mild hypertrophy group, moderate hypertrophy group and severe hypertrophy group. The baseline clinical data of patients were collected by medical record management system. All enrolled patients underwent cardiac magnetic resonance imaging (CMR). The presence and location of myocardial fibrosis were identified by CMR gadolinium contrast delayed enhancement (LGE). The range of LGE (LGE%) was calculated by visual analysis. The levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and cardiac troponin I (cTnI) in peripheral blood were measured . Results: A total of 48 patients ( age (46.4±14.3) years, 42 (87.5%) males) were enrolled. There were 34 LGE positive cases (fibrosis group) and 14 LGE negative cases (non-fibrosis group). Compared with non-fibrosis group, patients in fibrosis group were younger (P=0.038) and prevalence of NYHA grade Ⅲ/Ⅳ was higher (P=0.00). Compared with non-fibrosis group, patients in fibrosis group had thicker LVMWT (P= 0.008), higher left ventricular mass index(LVMI) (P=0.001), higher left ventricular end diastolic volume (LVEDV) (P=0.043), lower left ventricular ejection fraction (LVEF) and cardiac index (CI) (all P <0.05). The levels of NT-proBNP and cTnI were significantly higher in fibrosis group than in non-fibrosis group (2 760.5 (1 503.4, 3 783.6) ng / L vs. 861.3 (552.2, 1 092.8) ng / L, P=0.002; 0.970 (0.448, 1.684)μg / L vs. 0.147 (0.033, 0.251)μg / L, P=0.041).In fibrosis group, there were 15 cases of mild hypertrophy (mild hypertrophy group), 10 cases of moderate hypertrophy (moderate hypertrophy group), and 9 cases of severe hypertrophy (severe hypertrophy group). The LGE% and NT-proBNP and cTnI increased in proportion with increasing myocardial hypertrophy (P<0.05). LGE% was negatively correlated with age (r=-0.618, P=0.011), and positively correlated with NT-proBNP and cTnI levels (r=0.271, P=0.010; r=0.111,P=0.013, respectively), and positively correlated with LVEDV, LVMWT and LVMI (r=0.438, P=0.09; r=0.735, P=0.001; r=0.532, P=0.034, respectively). Conclusions: In patients with hypertrophic cardiomyopathy, the extent of myocardial fibrosis increases with the increase of myocardial hypertrophy. Myocardial fibrosis is negatively correlated with age, and positively correlated with NT-proBNP and cTnI, as well as LVEDV, LVMWT and LVMI in this patient cohort.

Inhibitory effect of pills against diethylnitrosamine-induced hepatocarcinogenesis in rats / 南方医科大学学报

OBJECTIVE@#To study the inhibitory effect of pills (BJJ) agaisnt diethylnitrosamine (DEN)-induced hepatocarcinogenesis and explore the relation between this effect and the inflammasome signaling pathway.@*METHODS@#Sixty-five male SD rats were randomly divided into control group, DEN model group, and 3 BJJ treatment groups at low, medium and high dose (with daily dose of 0.55, 1.1 and 2.2 g/kg, respectively, for 12 consecutive weeks starting from the 5th week after modeling). The pathological changes of the liver tissue were observed with HE and Masson staining, and serum levels of alanine transaminase (ALT), glutamic oxaloacetic transaminase (AST), alkaline phosphatase (ALP) and total bilirubin (TBIL) of the rats were detected using ELISA. Oxidation stress in the liver tissue was assessed with ELISA, and Western blotting and ELISA were used to detect the molecular expressions of inflammasome-related pathway.@*RESULTS@#BJJ significantly inhibited tumor growth in the liver of the rats. HE and Masson staining showed that BJJ treatment obviously ameliorated liver fibrosis and reduced cancer cell and inflammatory cell infiltration in the liver. BJJ significantly reduced elevations of serum ALT, AST, ALP and TBIL levels, increased the contents of superoxide dismutase, catalase and glutathione peroxidase in the liver and suppressed malondialdehyde in Den-treated rats. BJJ also dose-dependently decreased the expressions of NLRP3, apoptosis-associated speck-like protein (ASC), caspase-1, pro-IL-1β, pro-IL-18, IL-1β and IL-18 in the liver of Den-treated rats.@*CONCLUSIONS@#BJJ treatment can dose-dependently inhibit DEN-induced hepatocarcinogenesis by enhancing antioxidant capacity and down-regulating inflammatory-related pathways in rats.

OBJECTIVE@#Obesity is recognized as a significant risk factor for diabetes and hypertension. The present study aimed to examine the associations between adults'obesity risk and childhood and parental obesity.@*METHODS@#A total of 204 children aged 6-17 years were recruited in 2002 with an average follow-up period of 13.2 years. Height and body weight were measured by trained staffs. Overweight and obesity were defined based on the Chinese standard for children and adults. T-test, analysis of variance, and Chi-square analysis were used for single factor analysis. Multiple linear and logistic regression analyses were used to perform multifactor analysis.@*RESULTS@#The percentage of non-obese children who grew up to be non-obese adults was 62.6%, and that of obese children who grew up to be obese adults was 80.0%. There was a significant association between childhood body mass index (BMI) and adulthood BMI with a β regression coefficient of 3.76 [95% confidence interval (CI): 1.36-6.16], and between childhood obesity and adulthood obesity with an odds ratio of 5.76 (95% CI: 1.37-24.34). There was no statistical difference between parental obesity at baseline and children's adulthood obesity, after adjustment of confounders. Male participants and those aged 10.0-13.0 years had a higher risk of adulthood obesity with odds ratios of 2.50 (95% CI: 1.12-5.26) and 3.62 (95% CI: 1.17-11.24), respectively.@*CONCLUSION@#Childhood obesity is an important predictor of adulthood obesity.

Trends in Lipids Level and Dyslipidemia among Chinese Adults, 2002-2015 / 生物医学与环境科学（英文）

OBJECTIVE To investigate the trends of lipid profiles and dyslipidemia among Chinese adults from 2002 to 2015. METHODS Data were collected from three nationally representative cross-sectional surveys. Fasting venous blood samples were collected and serum lipids were tested by biochemical analysis and enzymatic determination. Lipid levels and the prevalence of dyslipidemia among adults were analyzed with complex sampling weighting adjustment for age and gender. RESULTS The weighted means of TC, TG, and LDL-c significantly increased linearly from 3.93, 1.12, and 2.12 mmol/L in 2002 to 4.59, 1.41, and 2.78 mmol/L in 2010 and then to 4.63, 1.47, and 2.87 mmol/L in 2015, respectively; by contrast, HDL-c levels decreased significantly from 1.30 mmol/L to 1.26 mmol/L over the same period. Similar trends in mean non-HDL-c and lipid-related ratios were observed. The weighted dyslipidemia prevalence linearly increased; in particular, hypercholesterolemia increased from 1.6% to 5.6% and then to 5.8%, hypertriglyceridemia increased from 5.7% to 13.6% and then to 15.0%, low HDL-c increased from 18.8% to 35.5% and then to 24.9%, and high LDL-c increased from 1.3% to 5.6% and then to 7.2% (P for trend < 0.001). CONCLUSION Dyslipidemia increased among Chinese adults from 2002 to 2015. Development of a comprehensive strategy to decrease lipid levels in this population is urgently required.

Objective: To explore the association of zinc finger ZBTB22 gene single nucleotide polymorphisms (SNPs) and schizophrenia in Han Chinese population. Methods: A case-control study was designed by genotyping four SNPs (rs3130100, rs1061783, rs1061801 and rs3130099) in 658 schizophrenia patients and 658 healthy controls of Chinese Han origin. SHEsis was used to analyze genotypic and allelic distributions, linkage disequilibrium and haplotype distribution. Results: rs3130100, rs1061783, and rs3130099 showed significant differences between the cases and controls in allele frequencies (P<0. 05 after Bonferroni correction), but no statistically significant differences were found in genotype frequencies after Bonferroni correction. Strong linkage disequilibrium was found among the four SNPs, and the frequency of haplotype TCGA significantly decreased in the schizophrenia patients (P=0.015 after Bonferroni correction). Conclusion: The ZBTB22 SNPs rs3130100, rs1061783 and rs3130099 may be associated with schizophrenia in Han Chinese population.

Aim To screen the differential microRNA (miRNA) expression profiles of different metastatic po-tential liver cancer cell lines,and predict miRNAs-reg-ulated target genes and their functions. Methods To-tal RNA was extracted and the miRNA expression pro-files were obtained by miRNA microarray chip hybrid-ization. The miRNAs whose expression had significant difference were selected by analyzing the miRNA difference expression profiles of the two different meta-static potential liver cancer cell lines, namely MHCC-97H(high-metastasis) and Hep3B(non-metastasis), which were compared with normal hepatocytes L02 re-spectively. Moreover, we analyzed the miRNA differ-ential expression profile between liver cancer cell lines MHCC-97H and Hep3B. The miRNAs were verified by qPCR and target genes were predicted by four softwares (TargetScan, miRanda, miRWalk, miRDB). To un-derstand the biological functions of predicted target genes, bioinformatics analysis was performed. Results The miRNA microarray results showed that the ex-pression of miR-192-5p and miR-215-5p significantly increased in liver cancer cell lines (MHCC-97H, Hep3B) when compared with normal hepatocytes L02, while miR-130a-3p and miR-196a-5p were significantly reduced; compared with Hep3B, the expression of miR-224-5p markedly increased in liver cancer cell line MHCC-97H, while miR-146a-5p, miR-483-3p and miR-200b-3p were significantly reduced. The re-sults of qRT-PCR were consistent with chip results. Conclusion There are differences of miRNA expres-sion profiles in different metastatic potential liver canc-er cell lines MHCC-97H, Hep3B, and they may par-ticipate in regulating the development and invasion of hepatocellular carcinoma.

Study on the in vivo-in vitro Correlation of Cinacalcet Hydrochloride Tablets / 中国药房

OBJECTIVE:To investigate the in vitro dissolution behavior and in vivo pharmacokinetics of Cinacalcet hydrochloride tablets, and to evaluate its in vivo-in vitro correlation (IVIVC). METHODS:HPLC method was adopted to determine the accumulative dissolution(Q) of Cinacalcet hydrochloride tablets in 8 kinds of medium [pH 1.2 hydrochloric acid solution,pH 2.0 hydrochloric acid solution,pH 4.5 acetate buffer solution,pH 6.8 phosphate buffer solution,water,artificial gastric fluid(SGF),full belly artificial intestinal fluid(FeSSIF),fasting artificial intestinal fluid(FaSSIF)],and the dissolution curves were drawn. HPLC-MS method was used to determine the blood concentrations of Cinacalcet hydrochloride tablets. A total of 12 healthy male volunteers were selected and given single oral dose of Cinacalcet hydrochloride tablets 75 mg under the state of fasting or satiety(high-fat food). The blood concentration of cinacalcet hydrochlorid was determined before medication(0 h)and 0.5,1,2,3,4,6,8,12,24 h after medication. Average blood concentration-time curves were drawn. The in vivo accumulative absorption percentage (F) of satiety group was calculated by using DAS 3.0 software. Linear regression of F with in vitro Q was carried out to analyze its IVIVC. RESULTS:There was great difference among dissolution curves of Cinacalcet hydrochloride tablets in 8 kinds of dissolution mediums. There were differences of AUC0→t,AUC0→∞ and cmax between fasting group and satiety group,with statistical significance(P＜0.05),showing high-fat food had significant effect on in vivo pharmacokinetics. Correlation coefficient of in vivo F in satiety group with in vitro Q of the tablets in FeSSIF was highest (0.977 9),manifesting good IVIVC (class A). CONCLUSIONS:The in vitro dissolution behavior of Cinacalcet hydrochloride tablets in FeSSIF(paddle method,50 r/min)is well associated with its in vivo pharmacokinetics,which can be used for predicting in vivo dissolution and absorption of the tablets.
