Diabetes mellitus(DM)is a major metabolic disease endangering global health,with diabetic ne-phropathy(DN)as a primary complication lacking curative therapy.Sporoderm-broken spores of Ganoderma lucidum(GLP),an herbal medicine,has been used for the treatment of metabolic disorders.In this study,DN was induced in Sprague-Dawley rats using streptozotocin(STZ)and a high-fat diet(HFD),and the protective mechanisms of GLP were investigated through transcriptomic,metabolomic,and network pharmacology(NP)analyses.0ur results demonstrated that GLP intervention ameliorated renal damage and inflammation levels in DN rats.Integrative metabolomic and transcriptomic analysis revealed that GLP treatment modulated glucose and cellular energy metabolisms by regulating relevant genes.GLP significantly suppressed the inflammations by impacting glucose and energy metabolism-related gene expression(Igfbp1 and Angptl4)and enhanced metabolic biomarkers of 4-Aminocatechol.In addition,NP analysis further indicated that GLP may efficiently alleviate DN via immune-related pathways.In conclusion,this study provides supportive evidence of the anti-inflammatory effects of GLP supplements,highlighting their potential for promising clinical applications in treating DN.

Diabetes mellitus (DM) is a major metabolic disease endangering global health, with diabetic nephropathy (DN) as a primary complication lacking curative therapy. Sporoderm-broken spores of Ganoderma lucidum (GLP), an herbal medicine, has been used for the treatment of metabolic disorders. In this study, DN was induced in Sprague-Dawley rats using streptozotocin (STZ) and a high-fat diet (HFD), and the protective mechanisms of GLP were investigated through transcriptomic, metabolomic, and network pharmacology (NP) analyses. Our results demonstrated that GLP intervention ameliorated renal damage and inflammation levels in DN rats. Integrative metabolomic and transcriptomic analysis revealed that GLP treatment modulated glucose and cellular energy metabolisms by regulating relevant genes. GLP significantly suppressed the inflammations by impacting glucose and energy metabolism-related gene expression (Igfbp1 and Angptl4) and enhanced metabolic biomarkers of 4-Aminocatechol. In addition, NP analysis further indicated that GLP may efficiently alleviate DN via immune-related pathways. In conclusion, this study provides supportive evidence of the anti-inflammatory effects of GLP supplements, highlighting their potential for promising clinical applications in treating DN.

Objective:To demonstrate the clinical significance of group A streptococcal infection (GAS) in patients with enthesitis related arthritis (ERA).Methods:A retrospective study was conducted on ERA (136) and PolyRF-/Oligo juvenile idiopathic arthritis (JIA) (272) patients in Beijing Children's Hospital from 2016 to 2018. Anti-streptococcal hemolysin "O" (ASO) was tested and documented in all patients. The infection rate of GAS was compared between patients with ERA and PolyRF-/Oligo JIA. Patients with ERA were divided to two groups according to the result of ASO (ASO positive and ASO negative). All the clinical data were documented and compared within the two groups. The statistical methods used mainly include t test, rank sum test, chi-square test, and Spearman correlation analysis.Results:The GAS infection rate of patients with ERA was higher than patients with PolyRF-/Oligo JIA (17.6% vs 9.5%, χ2=5.52, P=0.019). In ERA patients, clinical data were analyzed, and a statistical significant difference was observed in the presence of human leukocyte antigen (HLA)-B27 between ASO positive and ASO negative group [75.0%(18/24) vs 49.1%(55/112), χ2=5.329, P=0.021]. Statistical differences were found in Patrick's sign positive rate between the two groups [100%(24/24) vs 67.0%(75/112), χ2=10.61, P=0.001]. There was statistically significant difference between the two groups regarding the radiogr-aphic grading at the sacroiliac joint. More patients with positive ASO had grade Ⅲ damage at the sacroiliac joint compare to patients with negative ASO [68.2%(15/22) vs 28.4%(29/102), χ2=12.49, P<0.001]. The logarithmic of the ASO was slightly correlated with the radiographic grade of sacroiliac joint ( r=0.26, P=0.005). Conclusion:Patients with ERA are prone to be infected by GAS. It's probably related to HLA-B27 postivity for antigen presentation. Patients who were infected by GAS fre-quently have sacroiliac joint involvement, and tend to be more sever. This indicates that GAS may play an important role in the pathogenesis of sacroiliac joint destruction.

After freeze-drying, the ultrastructure of boar sperms was observed by optical and electron microscopy. The in vitro development ability of the sperm was also examined with intracytoplasmic sperm injection (ICSI). The rate of male pronuclear formation was (68.52%), for cleavage (59.17%) and for blastocyst formation (19.16%) of the trehalose group (0.2 mol/L), significantly higher than those of the 50 mmol/L EDTA group (64.59%, 56.26% and 15.62%) and the control group (35.36%, 52.33% and 8.60%) (P < 0.05). After storage for 60, 120 and 180 d at 4 degrees C, no significant difference in the in vitro development was observed (P > 0.05). The male pronuclear, cleavage and blastocyst formation after ICSI with freeze-dried spermatozoa incubated for 1 h was superior than those incubated for 2 h (P < 0.05). No significant differences in the structures after stored at 4 degrees C or -20 degrees C (P > 0.05) were observed between the trehalose group and EDTA group. The percent of B grade freeze-dried boar spermatozoa in the trehalose group was higher than that of the EDTA group (P < 0.05). Based on the ultrastructure observation, main cryogenic damage in freeze-dried boar spermatozoa was swelling, damage or rupture in the sperm acrosome, neck and tail.

status.Conclusion HPV6 and HPV-16 were the most two popular HPV types in the whole population,while HPV-16 was the most common type in CIN2+ population.HPV-16 seroprevalence increased with severity of cervical intraepithelial neoplasia.

Now syndrome study becomes the important research content in our country' TCM field,normalization of the symptoms standardization of syndromes especially becomes scientific research focal point in this field,furthermore some studies exists the conditions of symptoms short of norm and standards of syndrome differentiation discordant,as well stagnation of liver-QI with deficiency of the spleen is clinical common syndrome,so this article carried out all round analysis and investigations on the modern literature of stagnation of liver-QI with deficiency of the spleen syndrome recent ten years,to aim at analyzing the symptom characteristic and standards of syndrome differentiation on stagnation of liver-QI with deficiency of the spleen syndrome,to provide the bases of standardization and normalization of stagnation of liver-QI with deficiency of the spleen syndrome.
