Coronary heart disease (CHD) and stroke are the most well-known cardiovascular diseases, which share many common pathological basis. Yindan Xinnaotong soft capsule (YDXNT) is a commonly used Chinese patent medicine in the treatment of stroke and CHD. However, its action of mechanism of co-treatment for stroke and CHD is still unclear. The aim of this study was to explore the common mechanism of YDXNT in co-treatment of CHD and stroke using network pharmacology, experimental verification and molecular docking. An integrated literature mining and databases of IPA, ETCM, HERB, Swiss Target Prediction, OMIM and GeneCards were used to screen and predict active ingredients and potential targets of YDXNT in co-treatment of CHD and stroke. The protein-protein interaction network, GO analysis and pathway analysis were analyzed by IPA software. The effect of YDXNT on core targets was verified by immunofluorescence. UPLC-QTOF/MS and molecular docking were used to screen and predict the main active constituents of YDXNT and their interactions with core targets. A total of 151 potential targets are predicted for YDXNT in co-treatment of CHD and stroke. Hypoxia-inducible factor-1α (HIF1α)-matrix metalloproteinase-9 (MMP9)-mediated HIF1α signaling pathway serves as one of the common mechanisms. YDXNT could reduce the increase of mitochondrial fluorescence intensity and the protein expression of HIF1α and MMP9 in HL-1 and HA induced by oxygen and glucose deprivation/reperfusion (OGD/R) in a dose-dependent manner. Baicalin may be the material basis for treating stroke and CHD with YDXNT. In conclusion, the HIF1α signaling pathway is one of the common key mechanisms of YDXNT in the co-treatment of stroke and CHD. The study provides support and basis for the in-depth scientific connotation of the traditional Chinese medicine theory of "same treatment to different diseases".

A randomized, double-blind, placebo-controlled, multi-center phase Ⅱ clinical trial design was used in this study to recruit subjects who were in line with the syndrome of excess heat and fire toxin, and were diagnosed as recurrent oral ulcers, gingivitis, and acute pharyngitis. A total of 240 cases were included and randomly divided into a placebo group and a Huanglian Jiedu Pills group. The clinical efficacy of Huanglian Jiedu Pills in treating the syndrome of excess heat and fire toxin was evaluated by using the traditional Chinese medicine(TCM) syndrome scale. Enzyme-linked immunosorbent assay(ELISA) was used to determine and evaluate the levels of adenosine triphosphate(ATP), 4-hydroxynonenal(4-HNE), and adrenocorticotropic hormone(ACTH) in plasma of the two groups before and after administration and to predict their application value as clinical biomarkers. The results showed that the disappearance rate of main symptoms in the Huanglian Jiedu Pills group was 69.17%, and that in the placebo group was 50.83%. The comparison between the Huanglian Jiedu Pills group and the placebo group showed that 4-HNE before and after administration was statistically significant(P<0.05). The content of 4-HNE in the Huanglian Jiedu Pills group decreased significantly after administration(P<0.05), but that in the placebo group had no statistical significance and showed an upward trend. After administration, the content of ATP in both Huanglian Jiedu Pills group and placebo group decreased significantly(P<0.05), indicating that the energy metabolism disorder was significantly improved after administration of Huanglian Jiedu Pills and the body's self-healing ability also alleviated the increase in ATP level caused by the syndrome of excess heat and fire toxin to a certain extent. ACTH in both Huanglian Jiedu Pills group and placebo group decreased significantly after administration(P<0.05). It is concluded that Huanglian Jiedu Pills has a significant clinical effect, and can significantly improve the abnormal levels of ATP and 4-HNE in plasma caused by the syndrome of excess heat and fire toxin, which are speculated to be the effective clinical biomarkers for Huanglian Jiedu Pills to treat the syndrome of excess heat and fire toxin.

Objective:To investigate Helicobactor pylori (H. pylori) infection status and interfamilial transmission pattern in Zhengzhou area. Methods:A cross-sectional study was conducted from September 2020 to march 2021, among 731 individual from 266 families randomly selected from 9 communities of Zhengzhou area. H. pylori infection status was determined by serum antibody tests, and 13C-urea breath test was performed in the previously eradicated population to clarify the current infection status. The individual and familial infection rate, infection status for couples and children and adolescent were analyzed. Results:Among 731 individuals from 266 families, 397 of them were H. pylori positive. The individual infection rate was 54.31% (397/731); among infected individuals 77.83% (307/397) were infected with type Ⅰ strain, 22.67% (90/397) were infected by type Ⅱ strain. Annual household income ( χ2=0.419, 0.410, 0.213, all P>0.05), smoking history (χ 2=0.071, P>0.05), drinking history ( χ2=0.071, P>0.05), dining place ( χ2=0.009, P>0.05), gastrointestinal symptoms ( χ2=0.047, P>0.05), family history of gastric disease ( χ2=0.069, P>0.05), and history of gastric cancer ( χ2=0.004, P>0.05) had no significant differences between H. pylori-positive and -negative groups, but the infection rate in individuals with higher education level was lower ( χ2=4.449, P<0.05). The infection rate was significantly higher in≥18 age groups compared with<18 age groups ( χ2=6.531, 23.362, 20.671, 24.244, 37.948, 14.597 and 5.170, all P<0.05). The familial H. pylori infection rate was 87.59% (233/266), and in 61 families all member were infected (26.18%, 61/233). The positive rate was 23.08% (6/26) in 50 families with children under 18 years when both parents were infected. Among 231 coupled families, both couples were infected in 78 families (33.76%), one couple was infected in 113 families (48.92%), and both couples were not infected in 40 (17.32%). With the increase of marriage time, the infection rate of both spouses increased significantly ( χ2=7.775, 12.662, 15.487, all P<0.05). Conclusions:The distribution of H. pylori infection presents a family cluster pattern, and intrafamilial infection is an important transmission rout of H. pylori. The type I strain of H. pylori is the dominate strain in this area.

We reported a 54-year-old female patient with severe tricuspid regurgitation, who received mechanic valve in the mitral position 15 years ago. The patient’s Society of Thoracic Surgeons score was 8.27%, and was intolerant to open heart surgery, so she was recommended for transcatheter tricuspid valve replacement via right vena jugularis interna. The procedures were guided by echocardiography and X ray fluoroscopy on November 13, 2021, the prosthesis was implanted successfully, and the patient was recoved without any adverse events. After 1 month follow-up, her general condition was apparently improved.

Objective:To analyze the sequence characteristics，chromosomal location，gene structure，conserved motifs，phylogenetic evolution and differential gene expressions of the Cannabis sativa YABBY transcription factor family，in order to provide a molecular basis for in-depth study of YABBY gene function and theoretical support for the selection and breeding of superior hemp varieties. Method:The bio-informatics method was used to identify and analyze the CsYABBY gene family of the original hemp seed plant. PlantTFDB，ExPASy，MEME，CELLO，PLANTCARE and other online websites and TBtools，MEGA，DNAMAN and other software were used for prediction，visualization and analysis. Result:C. sativa contains 6 YABBY gene members distributed on 5 chromosomes，in which 5 members are localized in the nucleus and 1 in extracellular， they consist of 185-235 amino acids， and the isoelectric point is between 5.05 and 9.34， the molecular weight is between 20 582.45-26 282.7 Da. All of CsYABBY proteins contain two conserved domains， namely Zinc finger domain and YABBY domain. CsYABBY genes have multiple cis-acting elements，and their expressions differ in different tissues and cultivars. Conclusion:The expressions of CsYABBY may be affected by hormones and externally environmental factors. CsYABBY gene expressions are tissue-specific. In addition，YABBY transcription factor family may play an important role in regulating the development of C. sativa female flowers，and subfamilies YAB1 and YAB5 may be involved in the synthesis of cannabinoids.

Objective: To analyze the genetic characteristics of a five generations pedigree with homozygous familial hypercholesterolemia (HoFH). Methods: Prospective study. Twenty family members included a proband diagnosed as familial hyperlipidemia at the cardiology Department of Xi′an Children′s Hospital in October 2018 were research object. Clinical data were collected. Genome DNAs were extracted. Whole exons sequencing was performed on the proband using target capture next generation sequencing. Candidate gene mutation sites identified by bioinformatics were verified by Sanger sequencing in the family members. The genotype-phenotype correlation of the pedigree was analyzed between heterozygous mutation carriers and non-carriers. Results: The proband was a 7-years and 10-month-old boy. He was born with a roundgreen bean size yellow skin protuberance in the skin of the coccyx. Since the age of 3-4 years old, xanthoma-like lesions with a diameter of 0.5-1.5 cm gradually appeared in the skin of bilateral elbow joints, knee joints and Achilles tendon. The height, weight and intellectual development of the child were the same as those of normal children at the same age. No similar xanthoma-like lesion was found in the other family members. The proband′s total cholesterol (TC) reached 18.16-21.24 mmol/L, and his low density lipoproteincholesterol (LDL-C) was 14.08-15.51 mmol/L. Carotid ultrasonography showed diffuse sclerotic plaques in bilateral carotid and vertebral arteries, and color Doppler echocardiography revealed aortic valve thickening and calcification. Gene testing identified that the proband carried a homozygous mutation C. 418G>A (p. E140K) in LDLR gene inherited from his parents who had a consanguineous marriage and carried a heterozygous mutation of LDLR-E140K, respectively.The TC, LDL-C and apolipoproteinB (ApoB) of LDLR-E140K gene heterozygous carriers ((8.40±0.13), (6.79±0.01) and (1.95±0.05) mmol/L, respectively) were significantly higher than those of non-carriers ((4.59±0.28), (3.35±0.39) and (0.86±0.10) mmol/L, t=7.269, 4.595, 6.311, respectively, P<0.05). Conclusions LDLR-E140K gene homozygous mutation is first reported to be associated with most severe phenotype HoFH. The genotype-phenotype analysis of the pedigree shows that the clinical phenotype of the proband with homozygous mutation is the most serious, and all the heterozygous mutation carriers present with hypercholesterolemia phenotype. The investigation confirms that LDLR-E140K is the pathogenic variation of familial hyperlipidemia.

Objective: To investigate the impact on myocardial blood flow (MBF) quantitation with multi-pinhole cadmium zinc telluride (CZT)-SPECT with or without partial physical corrections. Methods: A total of 30 patients (18 males, 12 females; age: (63±9) years) with suspected or known coronary heart diseases who underwent dynamic SPECT from July 2018 to January 2019 in Fuwai Hospital were enrolled. Images were reconstructed using different corrections: no correction (NC), partial corrections ((noise reduction (NR), NR+ scatter correction (SC), NR+ SC+ resolution recovery (RR)), NR+ SC+ RR+ attenuation correction (AC; total corrections, TC). Kinetic modeling integrated one-tissue two-compartment model while using index of fitting quality (R²) and fraction blood volume (FBV) to assess the quality of modeling. Rest MBF (RMBF), stress MBF (SMBF) and myocardial flow reserve (MFR) quantified from no correction (NC) or partial corrections were compared with those of TC. Wilcoxon signed rank test and linear regression analysis were used to analyze the data. Results: Compared to TC, NC showed the lowest R² (rest: 0.69, stress: 0.78; z values: 4.78 and 4.78, both P<0.01) and highest FBV (rest: 0.37, stress: 0.40; z values: -3.40 and -3.30, both P<0.01). The improvement of R² and FBV was consistent with increased corrective terms. Compared with TC, NC overestimated SMBF and MFR (z values: 1.27 and -3.50, both P<0.01), all partial corrections overestimated RMBF and SBMF (z values: from -4.55 to 1.27, all P<0.01). NR and NR+ SC underestimated MFR (both P<0.05). Linear regression analysis showed that the regressive coefficients of RMBF between NC, NR, NR+ SC, NR+ SC+ RR and TC were 0.908-1.210, and Bland-Altman plots of RMBF demonstrated positive or negative biases (-0.07, 0.21, 0.26, 0.15 ml·min^-1·g^-1). The regression coefficients of SMBF were 1.129-1.308, and Bland-Altman plots demonstrated positive biases (0.60, 0.25, 0.28, 0.24 ml·min^-1·g^-1). The regression coefficients of MFR were 0.907-1.318, and Bland-Altman plots demonstrated positive or negative biases (0.70, -0.11, -0.05, 0.01). Conclusion Full physical corrections can improve the index of fitting quality in the kinetic modeling and reduce left ventricle spillover, which help to warrant the accuracy of SPECT myocardial blood flow quantitation with multi-pinhole CZR-SPECT.

Objective To investigate the percentage of regulatory T cells (Treg) in peripheral blood lymphocytes of patients with chronic brucellosis and the percentage change before and after treatment of different regimens,and to analyze the influence of Treg cell-induced immunosuppression on the therapeutic effect of chronic stage brucellosis.Methods Using case-control study,35 patients with chronic brucellosis who were hospitalized in Heilongjiang General Hospital of Agriculture Bureau [28 males,7 females,aged (45.37 ± 20.16) years old] were selected as case group.According to the treatment regimen,they were divided into standard treatment group (15 cases) and immune enhancer group (20 cases),the treatment was 20 d;30 cases of in-hospital health examinations were selected [16 males and 14 females,aged (35.53 ± 11.38) years old] as control group.Peripheral blood sample of the subject was collected before and after the treatment,the Treg cells as a percentage in peripheral blood lymphocytes were detected by flow cytometry.And the percentage change of Treg cells of brucellosis patients who underwent different treatment regimens was analyzed.Results Before treatment,the percentage of Treg cells in peripheral blood lymphocytes of the control group,the standard therapy and the immune enhancer groups [(1.69 ± 0.38)％,(3.12 ± 0.86)％,(3.05 ± 1.07)％] was significantly different (F =25.89,P ＜ 0.05);compared with the control group,the percentage of Treg cells in the peripheral blood lymphocytes of the standard treatment group and the immune enhancer group increased (P ＜ 0.05);there was no significant difference between the standard treatment group and the immune enhancer group (P ＞ 0.05).After treatment,the percentage of Treg cells in peripheral blood lymphocytes of the control group,the standard therapy and the immune enhancer groups [(1.69 ± 0.38)％,(3.06 ± 0.76)％,(2.85 ± 0.89)％] was significantly different (F =30.84,P ＜ 0.05);compared with the control group,the percentage of Treg cells in the peripheral blood lymphocytes of the standard treatment group and the immune enhancer group increased (P ＜ 0.05);there was no significant difference between the standard treatment group and the immune enhancer group (P ＞ 0.05),and compared with the same group before the treatment,respectively,the differences were not statistically significant (P ＞ 0.05).Conclusions The percentages of Treg cells in peripheral blood lymphocytes of the chronic brucellosis patient are not significantly changed before and after different treatment regimens.It suggests that the immunesuppression induced by Treg cells may be one of the reasons why the host organism cannot effectively remove residual Brucella in the body,which leads to chronic infection.

Objective To investigate the correlation and clinical significance between serum uric acid (SUA) levels and insulin resistance in type 2 diabetes(T2DM) with non-alcoholic fatty liver disease (NAFLD). Methods There were 54 T2DM patients with NAFLD in combined group ,50 cases in simple T2DM group and 37 cases in healthy group.The clinical parameters,SUA and insulin resistance (IR) levels were determined and compared among the three groups.The correlations among NAFLD,SUA levels and IR were analyzed.Results The SUA levels and IR index ( HOMA-IR) of the combined group were higher than those of the other two groups ( SUA:F=9.77,P=0.00;IR:H=122.13,P=0.00).The studies showed that NAFLD was positively correlated with SUA , TG,HOMA-IR(r =0.323,P =0.00;r =0.294,P =0.00;r =0.331,P=0.00).Logistic regression analysis revealed that IR,SUA and TG were the risk factors for T2DM with NAFLD(B=0.852,0.012,0.707).Conclusion The increase of SUA is independent risk factor for T 2DM with NAFLD,so to control SUA and improve insulin sensitivity can help to prevent the development of T 2DM with NAFLD.
