AIM:To explore the mechanisms behind the inhibition of lymphangiogenesis in pregnant rats with obstructive nephropathy and assess the protective effects on kidney function.METHODS:Forty nulliparous female Wi-star rats were randomly assigned to four groups:sham operation,sham operation+pregnancy,model,and Esaxerenone groups,with 10 rats in each group.Renal injury was induced in the model and Esaxerenone groups via unilateral ureteral obstruction(UUO).The other two groups underwent ureteral dissociation without ligation.Nine weeks post-UUO,female rats in the sham operation+pregnancy,model,and Esaxerenone groups were mated with male rats(2:1 ratio)to establish a rat model of obstructive nephropathy during pregnancy.Starting the day after UUO,rats in the Esaxerenone group re-ceived Esaxerenone at 1 mg·kg-1·d-1.On the 18th day of pregnancy,24-hour urine was collected using metabolic cages.The following day,the rats were sacrificed,serum samples collected,and the contralateral kidney removed.Blood urea ni-trogen(BUN)was measured using standard biochemical methods,and endogenous creatinine clearance rate(Ccr)was calculated.Kidney tissue pathology was assessed using HE,Masson,and Sirius red staining.Serum aldosterone levels were determined via ELISA.Immunohistochemistry,real-time PCR,and Western blot were employed to assess mineralo-corticoid receptor(MR)activation,lymphangiogenesis,signaling pathways,and fibrosis-related markers.RESULTS:Renal function tests revealed increased BUN levels and decreased Ccr in the model group(P<0.01).Pathological exami-nation showed dilated renal tubules,significant collagen deposition,and inflammatory cell infiltration in the model group.ELISA results indicated a significant increase in serum aldosterone levels in the model group(P<0.01).Immunohisto-chemistry showed enhanced nuclear translocation of MR in the kidneys of the model group post-activation.Western blot and real-time PCR demonstrated a marked increase in neutrophil gelatinase-associated lipocalin(NGAL)expression in the model group(P<0.01).Additionally,the expression of vascular endothelial growth factor C(VEGF-C)and its receptor VEGFR3 was significantly elevated in the renal tubulointerstitium of the model group,as shown by both immunohistochem-istry and real-time PCR(P<0.01).The PI3K/Akt signaling pathway was activated in the model group,with significantly increased phosphorylation levels observed primarily in renal tubular epithelial and interstitial cells(P<0.01).Collagen type III(Col III)expression,primarily in the renal tubulointerstitium,was also significantly upregulated in the model group,consistent with real-time PCR results(P<0.01).Esaxerenone treatment improved renal function,reduced patho-logical damage,inhibited aldosterone secretion,and downregulated the expression of MR,NGAL,VEGF-C,VEGFR3,phosphorylated PI3K,phosphorylated Akt,and Col III(P<0.01).CONCLUSION:Esaxerenone mitigates aldosterone-induced MR activation,modulates the PI3K/Akt signaling pathway,reduces lymphangiogenesis in the contralateral kidney of pregnant rats with obstructive nephropathy,decreases collagen deposition,and delays the progression of renal intersti-tial fibrosis.

OBJECTIVETo investigate the mechanism of di-2-ethylhexyl phthalate (DEHP) and cypermethrin (CYP) inducing gonadal dysgenesis in prepubertal male rats.

METHODSA total of 40 healthy 3-week-old specific pathogen-free male Sprague-Dawley rats were randomly and equally divided into four groups: control group (corn oil), DEHP group (500 mg/kg, dissolved in corn oil), CYP group (80 mg/kg, dissolved in corn oil), and combined exposure group (exposed to 500 mg/kg DEHP and 80 mg/kg CYP, dissolved in corn oil). Rats were treated by gavage administration once a day for 30 days. Twenty-four hours after the last exposure, the animals were sacrificed. The body weight and the wet weight of testis were determined, and the weight coefficient of testis was calculated. Radioimmunoassay was used to determine serum testosterone level. Ultrastructural-level histopathological changes of the testis were examined by transmission electron microscopy. The mRNA and protein expression of follicle stimulating hormone receptor (FSHR), androgen binding protein (ABP), inhibin beta-B (INHBB) and vimentin (VIM) were analyzed by real-time PCR and Western blot, respectively. Factorial design analysis of variance was used to compare differences between groups; interaction diagrams were used to determine the interaction between DEHP and CYP.

RESULTSCompared with those of the control group, the testis weights and testis coefficients of the DEHP, CYP, and combined exposure groups significantly decreased by 39.3-59.2%and 19.7-58.6%, respectively, and all exposure groups showed significant reductions in serum level of testosterone, ranging from 49.1% to 62.7% (P < 0.05 or P < 0.01). And all the exposure groups showed different levels of ultrastructural damages in the testes. Compared with that in the control group, the mRNA expression of FSHR, ABP, INHBB, and VIMin the DEHP group was down-regulated by 1.72, 2.64, 2.83 and 1.79 times, and their protein levels were significantly reduced by 65.2%, 53.7%, 70.1%, and 51.9% (P < 0.05 or P < 0.01). Significant decreases in mRNA expression of ABP (down 1.72 times) and INHBB (down 2.06 times) were observed in the CYP group, and their protein levels decreased by 38.3% and 49.7%, respectively (P < 0.05). The combined exposure to both DEHP and CYP resulted in big decreases in the mRNA levels of FSHR (down 1.62 times), ABP (down 2.00 times), INHBB (down 2.35 times), and VIM (down 1.54 times) and protein levels of FSHR (down 52.1%), INHBB (down 53.9%), and VIM (down 58.8%) (P < 0.05). Factorial design analysis of variance showed that the combination of two substances had an antagonistic effect on the expression of ABP and INHBB (P < 0.05).

CONCLUSIONDEHP and CYP, alone or combined, can lead to gonadal dysgenesis in prepubertal male rats. Both of them can disrupt functional mRNA and protein expression in Sertoli cells to certain levels. The combination of DEHP and CYP shows antagonistic effects, and DEHP has a stronger reproductive toxicity than CYP.

The length and diameter of trachea,bronchus and segmental bronchi were mea-sured from 70 cases (50 adults and 20 children).The length of the segmental bronchi of left lower lobe is always longer thanthat of left upper lobe.The length of the segmental bronchi of right lung showed a regular decreasefrom lower lobe to upper lobe.Using the multivariate statistical analysis the correlations between internalindices such as the length,diameter etc and external indices such as the height dia-meter of chest etc were also studied.
