Objective:
To investigate the association between high normal blood pressure, hypertension and microalbuminuria (MAU), so as to provide the basis for early screening and prevention of renal injury caused by hypertension.
Methods:
A multi-stage cluster random sampling method was used to select permanent residents aged 18 to 75 years from six provinces including Hebei, Hunan, Sichuan, Heilongjiang, Qinghai and Jiangxi from September to October 2021. Basic information and lifestyle behaviors were collected through questionnaires. Indices including height, weight and blood pressure were measured. Urinary microalbumin and creatinine were measured in 24-hour urine samples. The associations between high normal blood pressure, hypertension, and MAU were analyzed by using a multivariable logistic regression model.
Results:
A total of 1 982 residents were surveyed, with 996 residents aged <50 years (50.25%) and 986 residents aged ≥50 years (49.75%). There were 958 males (48.34%) and 1 024 females (51.66%). Normal blood pressure was observed in 653 residents (32.95%), high normal blood pressure in 748 (37.74%) and hypertension in 581 (29.31%). MAU was detected in 164 participants, with a detection rate of 8.27%. The detection rates of MAU among residents with normal blood pressure, high normal blood pressure, and hypertension were 2.14%, 8.16% and 15.32%, respectively, and the difference was statistically significant (P<0.05). Multivariable logistic regression analysis showed that after adjusting for gender, age, educational level, smoking, alcohol consumption, regular exercise and body mass index, the residents with high normal blood pressure (OR=3.535, 95%CI: 1.898-6.585) and hypertension (OR=7.232, 95%CI: 3.808-13.732) had higher risks of MAU compared to those with normal blood pressure; the residents with hypertension (OR=1.914, 95%CI: 1.340-2.735) had a higher risk of MAU compared to those with high normal blood pressure.
Conclusions
High normal blood pressure and hypertension are associated with an increased risk of MAU.

Objective To investigate the expression of Erbin in renal interstitial fibrosis (RIF) and the effect of over-expression of Erbin on transforming growth factor β1 (TGF-(β1)-induced epithelial-mesenchymal transition (EMT) in NRK52E cells. Methods In vivo, the model of renal fibrosis was induced by 5/6 subtotal nephrectomy in rat. Scr and BUN was detected and Masson staining was used to evaluate the level of renal tissue fibrosis. The location and expression of Erbin in renal tissue were detected by immunohistochemistry and Western blotting. In vitro, after NRK52E cells were treated by TGF-β1 (10 μg/L) for 72 h, immunofluorescence and Western blotting were used to obverse the expression and distribution of E-cadherin and α-SMA. The expression of Erbin mRNA and protein were detected by RT-PCR and Western blotting respectively. NRK52E cells were transiently transfected with Prk5-myc-Erbin plasmid via lipofectamine 2000, then the expressions of Erbin, E-cadherin and α-SMA were detected by Western blotting. Results (l)Compared to sham group with Scr (33.96±7.28) μmol/L and BUN (8.11±2.55) mmol/L, rats in 5/6 nephrectomy model with Scr (140.52±61.11) μmol/L and BUN (34.23±7.66) mmol/L revealed renal dysfunction. Masson staining indicated kidney interstitial fibrosis, and the expression of Erbin was significantly increased in renal tissue(2.9 folds), especially in tubular epithelia. (2)In vitro, the expressions of Erbin and α-SMA were markedly increased (2.3 folds and 2.1 folds, P<0.05, respectively) and the expression of E-cadherin was dramatically decreased in NRK52E cells stimulated by TGF-β1, which were consistent with immunofluorescence results. TGF-β1-induced E-cadherin suppression and a-SMA induction could be efficiently blocked by over-expression of Erbin (all P <0.05). Conclusions Erbin is up-regulated in renal interstitial fibrosis, and over-expression of Erbin can partly inhibit renal EMT induced by TGF-β1, which indicates Erbin playing an protective role in renal fibrosis.

Objective To observe the effect of CIP4(Cdc42 interacting protein 4)on human renal tubular epithelial to mesenchymal transition(EMT)induced by transforming growth factor β1(TGF-β1)and to study the associated mechanism. Methods Human proximal tubular epithelial cells (HK-2 cell line) were cultured with TGF-β1 (10μg/L) for 72 hours. The protein expressions of E-cadherin and α-SMA were measured by Western blotting. One set of siRNA oligos specific for CIP4 and CIP4 construction of the entire coding sequence were designed based on the full CIP4 sequence in GenBank. Then HK-2 cells were transfected with CIP4-siRNA or pcDNA3.1-hCIP4 via lipofactamine 2000. The protein expressions of CIP4, E-cadherin and α-SMA were evaluated respectively in control cells, TGF-β1 treated cells, siRNA transfected cells, pcDNA3.1-hCIP4-transfected cells by Western blotting. The distribution of E-cadherin and α-SMA was observed by confocal microscope. After TGF-β1-treated HK-2 cells were interferenced with specific inhibitor of PI3K-Akt (wortmannin) 1μmol/L for 48 hours, Western blotting was used to detect the CIP4 protein in control cells and interferenced cells. Results With TGF-β1 stimulation, the expression of E-cadherin protein was decreased markedly (P<0.05), and in contract, the expression of α-SMA were increased notably (P<0.05), which revealed that TGF-β1 could induce EMT. After transfected with CIP4-siRNA, the protein expression of E-cadherin was increased (P<0.05), and the protein expression of α-SMA was decreased (P<0.05). The EMT induced by TGF-β1 was effectively reversed. After transfected with pcDNA3.1-hCIP4, the expression of E-cadherin protein was down-regnlated (P<0.05), and the expression of α-SMA protein was up-regulated compared with control group (P<0.05), leading to EMT. After HK-2 cells were interferenced with wortmannin for 48 hours, the expression of CIP4 was decreased (P<0.05). Conclusion TGF-β1 upregulates the expression of CIP4 via PI3K-Akt pathway, and CIP4 may participate in EMT induced by TGF-β1.

Objective To observe the expression and localization of CIP4 (Cdc42 interacting protein-4) in the renal fibrosis and the effect of CIP4 on the expression of E-cadherin,vimentin and β-catenin tyrosine phosphorylation. Methods In vitro, the human tubular epithelial cells (HK-2 cell line) were cultured with 10 μg / L TGF-β1 for 72 h. The protein expressions of CIP4, E-cadherin, vimentin and β-catenin tyrosine phosphorylation were measured by Western blotting; the expression of CIP4 mRNA was detected by RT-PCR. The intracellular distribution of CIP4 was observe by confocal microscope. In vivo, Masson staining was used to evaluate the level of renal fibrosis; the expression and distribution of CIP4 in renal tissue were detected by immunohistochemistry. HK-2 cells were transfected with pcDNA3. 1-CIP via lipofectamine 2000. The expressions of E-cadherin, vimentin and β-catenin tyrosine phosphorylation level in the transfected cells were detected by Western blotting. Results The expressions of CIP4 mRNA and protein were up-regulated in renal tubular EMT cells. Most of CIP4 protein localized in cell membrane, and some was in cytoplasm. After stimulation by TGF-β1, the expression of CIP4 protein both in cytoplasm and nucleus was greatly increased (P <0.05),especially in cytoplasm. In vivo, CIP4 was expressed in renal tubular epithelia, but little expressed in glomeruli. In renal from 5/6 nephrectomized rats, CIP4 expression was significantly increased. In the CIP4 transfectants, the expression of CIP4, vimentin and β-catenin tyrosine phosphorylation level were up-regulated (P <0.05), but E-cadherin expression was suppressed (P <0.05).Conclusion The overexpression of CIP4 is likely to take part in the epithelial-to-mesenchymal transition process, thereby promoting the renal fibrosis.

In recent years, chimeric antigen receptor-modified T-cell (CAR-T) immunotherapy, as a new idea of tumor immunotherapy, has been proved to be effective in hematological diseases. More and more studies have been focusing on this field. At present, some progress have been made in the treatment of hepatocellular carcinoma with CAR-T, but some problems such as solid tumor inherent barrier, tumor microenvironment, immune escape and specific tumor associated antigens still need to be further figure out. Nevertheless, CAR-T immunotherapy will provide a more cutting-edge treatment for hepatocellular carcinoma immunotherapy. In addition, the combination of CAR-T and other methods may also be the direction to be explored in the next step.
