ObjectiveTo investigate the distribution of traditional Chinese medicine （TCM） syndrome patterns among postmenopausal women with dyslipidemia， and to examine the correlations of lipid parameters with bone mineral density （BMD） and bone metabolism markers across common TCM syndrome patterns， thereby providing a clinical reference for individualized integrative traditional Chinese and western medicine interventions stratified according to TCM syndrome patterns. MethodsA multi-center cross-sectional study was conducted among postmenopausal women aged 45-64 years with dyslipidemia. TCM syndromes were determined using a scale-based scoring method. BMD measurements were collected， and fasting venous blood samples were assayed for lipid parameters including total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C）， and bone metabolism biomarkers including osteocalcin （OST）， total procollagen type Ⅰ N-terminal propeptide （P1NP）， alkaline phosphatase （ALP）， bone-specific alkaline phosphatase （BALP）， β-isomerized C-terminal telopeptide of type Ⅰ collagen （β-CTX）， 25-hydroxyvitamin D ［25（OH）D］， and thyroid-stimulating hormone （TSH）. Chi-square tests were used to compare the distribution of dyslipidemia across different TCM syndromes. Spearman's rank correlation analysis was performed to evaluate the correlations between TCM syndrome patterns and dyslipidemia， as well as the correlations of lipid parameters with BMD and bone metabolism markers within each syndrome pattern. ResultsA total of 506 postmenopausal women with dyslipidemia were included， comprising 172 cases of spleen-kidney yang deficiency syndrome （33.99%）， 163 cases of phlegm-turbidity obstruction syndrome （32.21%）， 118 cases of liver-kidney yin deficiency syndrome （23.32%）， 33 cases of qi stagnation and blood stasis syndrome （6.52%）， and 20 cases of yin deficiency and yang hyperactivity syndrome （3.95%）. Phlegm-turbidity obstruction syndrome was negatively correlated with TC abnormality （r=-0.120， P=0.007） and positively correlated with TG abnormality （r=0.246， P＜0.001）. Spleen-kidney yang deficiency syndrome and liver-kidney yin deficiency syndrome were both negatively correlated with TG abnormality （r=-0.101， P=0.023； r=-0.116， P=0.009， respectively）. Further correlation analysis confirmed that phlegm-turbidity obstruction syndrome was negatively correlated with TC abnormality （r=-0.120） and significantly positively correlated with TG abnormality （r=0.246）. Both the spleen-kidney yang deficiency syndrome and liver-kidney yin deficiency syndrome were negatively correlated with TG abnormality （r=-0.101 and r=-0.116， respectively）. In patients with phlegm-turbidity obstruction syndrome， HDL-C was negatively correlated with BMD at the left femoral neck （r=-0.178， P=0.023） and at left total hip （r=-0.190， P=0.015）. In patients with liver-kidney yin deficiency syndrome， TG was positively correlated with BMD at the lumbar spine （L1-L4） and left total hip （r=0.214， P=0.020； r=0.221， P=0.016， respectively）. More significant correlations were observed in patients with spleen-kidney yang deficiency syndrome， TG was positively correlated with ALP （r=0.210， P=0.006）； TC was positively correlated with TSH and 25（OH）D （r=0.153， P=0.045； r= 0.231， P=0.002， respectively）； HDL-C was positively correlated with OST and 25（OH）D （r=0.156， P=0.040； r=0.228， P=0.003， respectively）； and LDL-C was positively correlated with TSH and 25（OH）D （r=0.156， P= 0.041； r=0.182， P=0.017， respectively）. In patients with liver-kidney yin deficiency syndrome， HDL-C was negatively correlated with TSH （r=-0.204， P=0.027）. ConclusionThe association between dyslipidemia and skeletal health in postmenopausal women varies across TCM syndromes. Lipid abnormalities in women with phlegm-turbidity obstruction syndrome or liver-kidney yin deficiency syndrome are accompanied primarily by site-specific alterations in BMD， whereas those in women with spleen-kidney yang deficiency syndrome are reflected mainly in changes in bone metabolism markers. These findings suggest that targeted intervention strategies should be developed according to TCM syndrome characteristics for postmenopausal women with dyslipidemia.

Objective To study the relationship between serum urine regulator protein and cystatin C levels and pathological characteristics and prognosis in patients with hypertensive nephropathy.Methods A total of 100 patients admitted in the hospital from August 2021 to October 2022 were selected as the study group,and 40 healthy persons who underwent the physical examination in the hospital were selected as the control group,complete data of all patients were collected and analyzed,the levels of serum urinary regulatory protein and cystatin C in each group were tested,and the relationship between serum urinary regulatory protein and cysta-tin C levels,pathological characteristics,and prognosis was analyzed.Results The urine regulatory protein and glomerular filtration rate in the study group were lower than those in the control group,but cystatin C,u-rea nitrogen,and blood creatinine were all higher than those in the control group,and the differences were sta-tistically significant(P＜0.05).Urinary regulatory protein was negatively correlated with urea nitrogen and blood creatinine,but positively correlated with glomerular filtration rate(P＜0.05).Cystatin C was positively correlated with urea nitrogen and blood creatinine,but negatively correlated with glomerular filtration rate(P＜0.05).Urinary regulatory protein level was related to crescent formation,renal tubular atrophy/intersti-tial fibrosis(P＜0.05),while level the expression of cystatin C was related to glomerular segmental sclerosis,glomerular glomerular sclerosis,and glomerular ischemic shrinkage(P＜0.05).The survival rate of the high urinary regulatory protein level group(≥126.49 ng/mL)was higher than that of the low urinary regulatory protein level group(＜126.49 ng/mL),while the survival rate of the high cystatin C level group(≥2.43 mg/L)was lower than that of the low cystatin C level group(＜2.43 mg/L)(P＜0.05).Urinary regulatory protein,cystatin C,renal tubular atrophy/interstitial fibrosis were factors that affected the occurrence of end-stage renal disease in hypertensive nephropathy(P＜0.05).Conclusion Hypertensive kidney disease patients u-sually have higher levels of cystatin C and lower levels of urinary regulatory protein,among which cystatin C is closely related to pathological features of glomerular segmental sclerosis,glomerular glomerular sclerosis,and glomerular is-chemic shrinkage,and urinary regulatory protein is closely related to crescent formation,renal tubular atrophy/intersti-tial fibrosis.In addition,urinary regulatory protein and cystatin C have a significant impact on the development of hy-pertensive nephropathy into end-stage renal disease,and could become important indicators for evaluating patient prognosis.

The ORF sequence of glycosyltransferase gene BcUGT1 cloned from Bupleurum chinense DC. was analyzed and its three dimentional structure was predicted. Using qRT-PCR method, the expression characteristics of BcUGT1 after methyl jasmonate (MeJA) induction and in different plant tissues were investigated. The results showed that BcUGT1 may be involved in saikosaponin biosynthesis in B. chinense. Thereafter, the recombinant vectors of BcUGT1 were constructed for its expression in E. coli. The target protein was successfully expressed and purified. In the present study, three vectors, pRSET-A, pET-28a (+) and pET-30a (+), and three isolates of E. coli, BL21 (DE3) plysS, BL21A1 and BL21-CodonPlus (DE3)-RIPL were used under different induction conditions, such as different concentrations and during times of inducers (L-arabinose and IPTG) and different inducing temperatures. The results showed that in the condition of 0.5 or 1 mmol x L(-1) IPTG, 16 degrees C, 20 h, target protein expressed in BL21-CodonPlus (DE3)-RIPL with pET-28a (+) or pET-30a (+) as vector. Using PrepEase His-tagged protein purification kit, the target protein was purified. The present work will be helpful for follow-up bio-function analysis of BcUGT1.
