Varicocele is a common disease of the male reproductive system, and the pampiniform plexus in the spermatic cord manifests abnormal dilatation, extension, and circuity, which is a vasculopathy. In this article, we believe that the relevance of the essence chamber collaterals to the spermatic vein in terms of anatomical morphology and physiological function is high and that when pathogenic qi invades the essence chamber, the qi and collaterals of the essence chamber are out of harmony, the fluid collaterals are impassable, and the blood collaterals are obstrcuted, and the essence chamber collaterals are blockaded with several pathological products, and even intermingled phlegm and blood stasis in the blood collaterals and form vascular clusters, resulting in the formation and development of varicocele. Based on this, this article proposes the core treatment principle of healing, harmonizing, activating, and dredging the collaterals, with the basic treatment method of nourishing qi and harmonizing collaterals, activating blood collaterals, and dredging blood stasis to, respectively treat degree Ⅰ, Ⅱ, and Ⅲ varicocele, aiming to prevent the change of the varicocele, dredge the curvature of the varicocele, and dissipate the knots of the varicocele. The proposal of essence chamber collaterals is of great significance to understanding the common law and pathological aspects of the occurrence and development of essence collateral and vascular lesions from the perspective of integrated traditional Chinese and Western medicine.

The peroxisome proliferator-activated receptor gamma(peroxisome proliferator-activated receptor gamma,coactivator 1 beta,PPARGC1B)gene is an intranuclear receptor transcription fac-tor responsible for regulating the expression of target genes.To comprehend the characteristics and mutations of the PPARGC1B gene within the Sichuan yak population,the SNP loci of the PPARGC1B gene were identified through direct sequencing of PCR products.Additionally,the cod-ing region of the PPARGC1B gene was obtained via PCR amplification and sequencing.Bioinforma-tics analyses were conducted to predict protein-coding and mRNA secondary structure.This study identified four exon SNP mutation sites(E9-189A→C,E9-387G→A,E9-542C→T,and E9-554T→C)based on the single nucleotide polymorphism analysis of the PPARGC1B gene in Sichuan yaks.Notably,the E9-387G→A and E9-554T→C loci exhibited significant correlations with shear force and backfat thickness in Sichuan yaks.Subsequently,bioinformatics analysis of the four mutation sites revealed that the PPARGC1B protein is an acidic,unstable,non-transmembrane,and non-secretory hydrophilic protein with a coiled helix structure.It lacks a signal peptide and transmembrane region,predominantly functions in the nucleus,and features 106 phosphorylation sites,one glycosylation site,and one conserved RRM structure.The secondary structure comprises mainly α-helix and random coils.Although the protein structure of the PPARGC1B gene remained unchanged post-mutation,there were significant differences in mRNA secondary structure.These findings suggest that the polymorphic loci of the PPARGC1B gene in Sichuan yaks could serve as a theoretical basis for enhancing meat quality traits through molecular biological methods,presen-ting practical applications in breeding.

The SNP loci of ACOX1 gene in 83 China Holstein cows were detected by PCR amplifica-tion and direct sequencing,and the association between the genetic polymorphism loci of ACOX 1 gene and milk quality traits of China Holstein cows was analyzed by SPSS 25.0 software.The re-sults showed that a SNP locus I3-2 267 G→C was found in the third intron of ACOX1 gene,it was moderately polymorphic and in Hardy Weinberg equilibrium in the population.By correlation anal-ysis,it was found that the SNP locus was significantly related to the somatic cell content and cor-rected milk quantity of dairy cows.The I3-2 267 G→C locus of ACOX1 gene can be used as a mo-lecular marker of quality traits of Holstein cows in China,and provide reference for the study of quality traits of Holstein cows in China.

The gene encoding regulatory subunit 15 A of protein phosphatase 1 produces a protein that is a universally present protein phosphatase in eukaryotic cells.In this study,genomic DNAs were extracted from the blood of 89 Chinese Holstein cows and were used as templates for PCR amplification of the target fragment of the PPP1R15A gene.The product was tested and a polymor-phic site,E3-250T＞A was found.The polymorphism of this side and its correlation with milk pro-duction traits in Chinese Holstein cattle were statistically analyzed using SPSS 23.0 software.The findings revealed three genotypes at this site:AA,AT and TT.Cows possessing the AT and TT genotypes exhibited significant differences(P＜0.01)in milk fat and solid non-fat content com-pared to those with the AA genotype.While no significant differences were noted for other milk production traits,including milk yield,protein,lactose,somatic cell count,blood urea nitrogen,and corrected milk.The identification of functional SNPs in the PPP1R15A gene provides a theoretical basis for further research and identification of causal variations in the cow PPP1R15A gene.

Objective:To investigate the association between triglyceride-glucose (TyG) index and all-cause mortality in elderly patients with hypertension and coronary artery disease.Methods:This was a retrospective cohort study, a total of 5 640 elderly inpatients (≥65 years) with hypertension and coronary artery disease who were admitted to the Department of Cardiology, Liberation Army General Hospital from August 2008 to July 2018 were enrolled in this study. The baseline clinical data of the patients were collected and the TyG index was calculated. Patients were divided into four groups according to their TyG index quartiles: TyG index<8.31 ( Q1 group, n=1 392), 8.31≤TyG index<8.67 ( Q2 group, n=1 417), 8.67≤TyG index<9.07 ( Q3 group, n=1 427), and TyG index≥9.07 ( Q4 group, n=1 404). All patients were followed up by obtaining outpatient/rehospitalization records or by telephone. The primary endpoint was all-cause mortality. Log-rank test was used to compare the cumulative all-cause mortality among groups. Cox proportional hazard regression model was used to analyze the risk of all-cause mortality in each group (the Q2 group with the lowest all-cause mortality was used as a reference), after adjusting for confounding factors, Restricted cubic spline analysis (RCS) was used to determine the association between TyG index and risk of all-cause mortality. Results:During a follow-up of 6.44 (4.70, 8.85) years, 1 037 all-cause deaths (18.39 %) were documented. The cumulative all-cause mortality in Q1- Q4 groups was 16.52%, 16.51%, 17.59% and 22.93%, respectively, and the difference was statistically significant ( χ2=26.49, P<0.01). In the Cox regression model, compared with Q2 group (reference), the HR (95% CI) for all-cause mortality was 1.06 (0.88-1.28) in the Q1 group, 1.23 (1.02-1.48) in the Q3 group and 1.48 (1.23-1.77) in the Q4 group, respectively ( P for trend<0.01). RCS curve analysis showed that when the TyG index was greater than 8.67, the risk of all-cause mortality increased with the TyG index, and there was a linear relationship between TyG index and all-cause mortality in this patient cohort (non-linearity P=0.31). Conclusion:The elevated TyG index is significantly associated with a higher risk for all-cause mortality in elderly hypertension and coronary artery disease patients.

The theory of "brain-heart-kidney-semen chamber" axis is proposed based on the basic theories of traditional Chinese medicine， the modern physiological characteristics of men's diseases， and clinical practice. According to this theory， dysfunctions of the brain， heart， kidney， and semen chamber are the core mechanisms for the occurrence of premature ejaculation， and the loss of control of the opening and closing of the seminal orifices due to the dysfunction of the semen chamber is the final link in the occurrence of premature ejaculation. The treatment of premature ejaculation based on the theory of "brain-heart-kidney-essence chamber" axis highlights the overall regulation of the Zang-fu organs involved in the disease， while focusing on the simultaneous treatment of the mind and body. By exploring the biological basis of the "brain-heart-kidney-essence chamber" axis and premature ejaculation， we propose that the biological basis of premature ejaculation and the axis is mainly related to the function decline of the local brain area， neuromodulation malfunction， central neurotransmitter imbalance， endocrine disorders， and enhanced sensory afferents of the penis. This study aims at providing a new approach for the prevention and treatment of premature ejaculation by traditional Chinese medicine and a scientific basis for the development of more effective therapeutic methods.

Objective:To investigate the expression of Toll-like receptor 4(TLR4)and extracellular signal-regulated protein kinase 1/2(ERK1/2)in decidua tissue of patients with unexplained spontaneous abortion and their correlation.Methods:The expres-sions of TLR4,ERK1/2 and p-ERK1/2 in decidua tissues of 32 patients with unexplained spontaneous abortion(abortion group)and 32 normal pregnancy(control group)were detected by immunohistochemistry and Western blot,respectively.The correlation between TLR4 and p-ERK1/2 in abortion group were analyzed by Pearson hierarchical correlation analysis.Results:In immunohistochemical experiments,the cytoplasm of decidua cells in the two groups is the expression locus of TLR4,ERK1/2 and p-ERK1/2,the expression of the three proteins were different,and the expressions of TLR4 and p-ERK1/2 in abortion group were significantly higher than that in control group(P<0.01).There was no significant difference in ERK1/2 expression between abortion group and control group(P>0.05);In decidua tissue samples of abortion group,the protein level of TLR4 was higher than that of control group(P<0.05);the pro-tein level of p-ERK1/2 was significantly higher than that of control group(P<0.01),and the protein level of ERK1/2 in decidua tissue of abortion group was not statistically different from that of control group(P>0.05).TLR4 was positively correlated with p-ERK1/2 expression in abortion group(r=0.890,P<0.01).Conclusion:Abnormal activation of TLR4/ERK1/2 signaling pathway may be one of the mechanisms of unexplained spontaneous abortion.
