Objective:To investigate the changes of home blood pressure from weekdays to weekends and its influencing factors.Methods:This study was a national multicenter prospective registry study. Data came from the registry study on the “Action of controlling home blood pressure to target in ten thousand patients”. Hypertension patients receiving antihypertensive drugs in the above study were included, and the general clinical data of the enrolled patients were collected. Patients′ office and home blood pressure were measured at baseline, followed by home blood pressure measurements for 7 consecutive days, and blood pressure trends over a one-week period were analyzed. Multivariate linear stepwise regression was used to investigate the influencing factors of blood pressure change from weekdays to weekends, and subgroup analysis was conducted according to body mass index, alcohol consumption, fasting blood glucose ≥6.1 mmol/L or diabetes mellitus. Kappa consistency test was used to analyze the influence of removing weekend blood pressure data on home blood pressure monitoring results. Results:A total of 3 228 hypertensive patients aged (66.2±7.6) years were included, including 1 612 (49.9%) males. The weekly blood pressure changes of the study subjects showed a trend of gradually increasing during working days (Monday to Friday) and decreasing during weekends (Saturday to Sunday). The blood pressure on weekends was lower than that on weekdays, but the difference was not statistically significant ((128.2±13.7)/(79.7±8.7) mmHg vs. (128.3±12.9)/(79.8±8.3) mmHg, all P>0.05; 1 mmHg=0.133 kPa). The blood pressure on Sunday was significantly lower than that on Friday ((127.9±13.3)/(79.6±9.1) mmHg vs. (128.5±13.3)/(80.0±9.0) mmHg, all P<0.05). Subgroup analysis showed that hypertensive patients who were overweight and obese, drank alcohol, and had fasting blood glucose≥6.1 mmol/L or combined diabetes mellitus had a smaller decrease or increasing trend in home blood pressure from weekdays to weekends. Consistency test results showed that the mean blood pressure after removing the 2-day home blood pressure data on weekends was consistent with the mean blood pressure of one week ( Kappa=0.90). The mean blood pressure after removing only the blood pressure data of Sunday was slightly less consistent with the mean blood pressure of one week ( Kappa=0.88). Conclusions:The home blood pressure level of hypertensive patients receiving antihypertensive drugs showed a trend of gradually increasing during working days and decreasing at weekends. People with hypertension who were overweight and obese, drank alcohol, had high fasting blood sugar, or had combined diabetes mellitus, and their home blood pressure decreased less or increased from weekdays to weekends. The removal of 1-day Sunday blood pressure data but not 2-day weekend blood pressure data had impact on the one-week home blood pressure monitoring results.

Chinese medicine entered a significant period from foundation to maturity between Han and Tang dynasties when the Chinese traditional stomatology was a key stage. Sorting and analysis of existing literature and research outcomes have showed that current research on stomatology between Han and Tang dynasties focuses on oral physiology, pathology, diagnosis and treatment, and health care. It also involves stomatology history and explanation of termino-logies related to mouth and teeth recorded in medical books, use of simple methods, and thinking with citation and analysis of literature simply listed and reasoning preliminarily deducted. From the macro perspective, current research has not unveiled the whole picture of stomatology between the two dynasties and left a series of key issues unresolved. Thus, new methods should be developed and employed to carry out medical research on stomatology between Han and Tang dynasties given that is has a prosperous future.

In recent years, the potential hepatotoxicity of green tea extract (GTE) has attracted more and more attention. With reference to the current studies on liver injury caused by GTE and the latest drug hepatotoxicity classification, this article systematically elaborates on the objectivity and causal mechanisms of liver injury caused by GTE. Based on the main risk factors for liver injury caused by GTE, this article also proposes recommendations for safe and rational use of such products, so as to provide valuable insights for in-depth research on the mechanism of liver injury caused by GTE and risk prevention and control, and meanwhile, it also provides an important reference for the therapeutic use of GTE to improve health conditions.

In order to verify the correlation between Polygonum multiflorum-induced liver injury and HLA-B*35 : 01 alleles, six hospitalized patients diagnosed with Polygonum multiflorum-induced liver injury (PM-DILI) were selected, and their clinicopathological data were collected. Simultaneously, blood HLA-B* 35 : 01 allele detection was performed. Among the six PM-DILI cases, 4 were male, aged 38.83 ± 10.13 years old. The types of liver injury were hepatocellular injury types in all, and the severity of liver injury in five cases was grade 3. The histological presentations were acute hepatitis and acute cholestatic hepatitis. PM-DILI cases were all HLA-B*35:01 carriers, with a carrier rate of 100%. This finding indicates that PM-DILI is significantly correlated with HLA-B*35:01 alleles. Therefore, HLA-B*35 : 01 alleles can be used as an important predictive indicator for PM-DILI.

Objective To explore the influence of rs1360780 T risk allele of FK506-binding protein 5 (FKBP5) gene on the brain function under resting-state and its association with clinical symptoms as well as immune function in patients with major depressive disorder (MDD).Methods Totally 147 MDD patients and 61 gender-,age-,and education-matched healthy controls were scanned with 3.0T MRI Scanner and genotyped.The peripheral serum immunoglobulin and complement were measured.The main effect of the disease,the genotype and their interaction effects were analyzed using regional homogeneity (ReHo) by two-way ANOVA.Abnormal brain activity was identified in T risk allele carriers of rs1360780 and non-risk CC individuals in MDD using post hoc analyses.Correlation analyses were performed between ReHo values of significant brain regions and the total score,five-factor scores of Hamilton rating scale for depression (HAMD-17),serum levels of immunoglobulin and plasma complement component in MDD patients.Results (1) The results of 2x 2 ANOVA showed the interaction effects located in the left opercular part of inferior frontal gyrus (MNI:x,y,z =-42,6,9;F=10.83),right opercular part of inferior frontal gyrus (MNI:x,y,z =30,6,33;F=15.05),left medial superior frontal gyrus (MNI:x,y,z=-9,54,0;F=9.17) and left pallidum (MNI:x,y,z =-12,6,-6;F=11.37) (Alphasim corrected,P＜ 0.05).(2) In post-hoc analyses for the main effect of genotype,T+ carriers with MDD showed increased ReHo values in the right opercular part of inferior frontal gyrus (MNI:x,y,z=60,12,6;t=2.88) compared with CC carriers;for the effect of diseaseby-genotype interaction,T+ carriers with MDD showed increased ReHo values in the right opercular part of inferior frontal gyrus (MNI:x,y,z=30,6,33;t=2.96) and decreased ReHo values in the left orbital part of inferior frontal gyrus (MNI:x,y,z =-21,9,-18;t =-3.21) (Alphasim corrected,P＜ 0.05) in contrast to CC carriers.(3)Pearson's correlation showed that the average ReHo values of the right opercular part of inferior frontal gyrus negatively correlated with the content of immunoglobulin G (r=-0.528,P=O.0016,Bonferroni corrected) and positively correlated with anxiety/somatization factor score (r=0.421,P＜0.001,Bonferroni corrected) in T + carrìers with MDD.Conclusion The results of this study suggest that rs1360780 T-risk allele of FKBP5 gene is involved in the changes of local neural activity in the right opercular part of inferior frontal gyrus of depressed patients and could potentially indicate a neuropathological mechanism of anxiety somatic symptoms and immune dysfunction in depression.

The main constituents of a typical medicinal herb,Polygonum muMflorum (Heshouwu in Chinese),that induces idiosyncratic liver injury remain unclear.Our previous work has shown that cotreatment with a nontoxic dose of lipopolysaccharide (LPS) and therapeutic dose of Heshouwu can induce liver injury in rats,whereas the solo treatment cannot induce observable injury.In the present work,using the constituent "knock-out" and "knock-in" strategy,we found that the ethyl acetate (EA) extract of Heshouwu displayed comparable idiosyncratic hepatotoxicity to the whole extract in LPS-treated rats.Results indicated a significant elevation of plasma alanine aminotransferase,aspartate aminotransferase,and liver histologic changes,whereas other separated fractions failed to induce liver injury.The mixture of EA extract with other separated fractions induced comparable idiosyncratic hepatotoxicity to the whole extract in LPS-treated rats.Chemical analysis further revealed that 2,3,5,4'-tetrahydroxy trans-stilbene-2-O-β-glucoside (trans-SG) and its cis-isomer were the two major compounds in EA extract.Furthermore,the isolated cis-,and not its trans-isomer,displayed comparable idiosyncratic hepatotoxicity to EA extract in LPS-treated rats.Higher contents of cis-SG were detected in Heshouwu liquor or preparations from actual liver intoxication patients associated with Heshouwu compared with general collected samples.In addition,plasma metabolomics analysis showed that cis-SG-disturbing enriched pathways remarkably differed from trans-SG ones in LPS-treated rats.All these results suggested that cis-SG was closely associated with the idiosyncratic hepatotoxicity of Heshouwu.Considering that the cis-trans isomerization of transSG was mediated by ultraviolet light or sunlight,our findings serve as reference for controlling photoisomerization in drug discovery and for the clinical use of Heshouwu and stilbene-related medications.

Objective To investigate the hepatoprotective effects of Paeoniae Radix Rubra (PRR) at different doses against α-naphthylisothiocyanate (α-NIT)-induced acute cholestatic hepatitis in rats.Methods Rats were ig administrated with vehicle or PRR [(1,9,18,36,54,72,and 81 g/(kg·d)] 3 d before and 2 d after α-NIT (60 mg/kg) ig administration.The general status of rats,histopathology of liver,serum alanine aminotransaminase,aspartate aminotransaminase,total bilirubin,direct bilirubin,and alkaline phosphatase levels,were observed at respective time points (24 and 48 h) after α-NIT administration.Using cluster analysis and correspondence analysis,the dose-effect-response relationships of PRR were evaluated.Results The results showed that compared with model group,the serum biochemistry index significantly decreased with the increasing of PRR dosage (P ＜ 0.01),and the change and necrosis of hepatic cellula,and inflammatory cell infiltration were gradually alleviated.However,the improvement was not obviously found in the low-dose group [1 g/(kg·d)].The cluster analysis and correspondence analysis results showed that different doses of PRR could significantly ameliorate α-NIT-induced acute cholestatic hepatitis of rats in a dose-dependent manner.Conclusion The experiments show that administration doses of PRR in clinical use should be added properly in order to gain the expectant therapeutic effect,especially in the treatment of heavy acute cholestasis hepatitis.

Objective Kunming strain(KM) mice were used as animal models. Nontoxic dextran conjugated with tetramethylrhodamine(TMR)and fluorecein isothiocyante(FITC)was microinjected to two of the 2-cell blastomere as molecular probe to trace the development fate of the blastomere ,in order to figure out the mechanisms of the formation of Em-Ab axis. Methods FITC- dextran was injected to zygote in order to make sure if it is noxious. Two blastomeres of 2-cell embryo were injected FITC- dextran and TMR- dextran respectively. Results When labeled embryo develeped to blastocyst, distribution of progeny of 2-cell embryo blastomeres can be detected.Conclusion The cells of blastomere randomly distributed either embryonic parts or extraembryonic parts of blastocyst.
