AIM:To investigate the therapeutic effects and potential mechanism of pachymic acid(PA)on li-popolysaccharide(LPS)-induced acute kidney injury(AKI)in mice.METHODS:(1)Genes related to AKI were screened using the DAVID database.Core genes were identified by intersecting related genes and analyzed using Cyto-scape software.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analyses were performed through the DAVID database for the cross-targets.Molecular docking and activity assays were conducted on the primary core targets.(2)A total of 100 C57BL/6J mice were randomly divided into five groups:normal control(NC),model(LPS),solvent control(LPS+DMSO),and treatment groups(LPS+PA-10 and LPS+PA-20),with 20 mice in each group.The LPS-AKI model was established by intraperitoneal injection of 18 mg/kg LPS.The treatment groups received 10 mg/kg and 20 mg/kg PA,respectively,and the solvent control group was administered an equivalent dose of DMSO.Mice were euthanized 24 h after injection.Serum was collected for biochemical analysis,and Western blot was used to detect neutro-phil gelatinase-associated lipocalin(NGAL),kidney injury molecule-1(KIM-1),caspase-3,cleaved caspase-3,interleu-kin-1β(IL-1β),and monocyte chemoattractant protein-1(MCP-1)protein expression.RT-qPCR was employed to detect inflammatory factor mRNA levels.Molecular docking was used to simulate the optimal binding site of PA to caspase-3.En-zyme activity assays were performed to assess caspase protein activity,and renal lesions were observed via hematoxylin and eosin(HE)staining.Apoptosis was detected by TUNEL staining.RESULTS:(1)Thirty-one potential targets of PA against AKI were identified through network pharmacology.GO and KEGG enrichment analyses indicated that these tar-gets were primarily involved in immune response,inflammatory processes,apoptosis and survival,angiogenesis and hemo-dynamics,oxidative stress,and endoplasmic reticulum stress.Key targets included CASP3(caspase-3),PTGS2,BCL2,CCL2,and CYP219.(2)PA treatment improved renal function and reduced tubular epithelial injury.It significantly de-creased NGAL,KIM-1,and cleaved caspase-3 protein levels,as well as inflammatory factors TNF-α,IL-1β,and MCP-1 mRNA and protein expression.PA also reduced apoptosis of renal tubular epithelial cells.Enzyme activity assays and mo-lecular docking revealed that PA exerted its anti-apoptotic effect by directly binding to caspase-3,thereby inhibiting its ac-tivation by caspase-8.CONCLUSION:PA demonstrated a therapeutic effect in LPS-AKI,potentially through the inhibi-tion of inflammatory factor synthesis and release,as well as the inhibition of caspase-3 activation by caspase-8,reducing apoptosis in renal tubular epithelial cells.

ObjectiveTo investigate the role and mechanism of DNA repair regulation in the process of hepatocellular carcinoma (HCC) recurrence. MethodsHCC tissue samples were collected from the patients with recurrence within two years or the patients with a good prognosis after 5 years, and the Tandem Mass Tag-labeled quantification proteomic study was used to analyze the differentially expressed proteins enriched in the four pathways of DNA replication, mismatch repair, base excision repair, and nucleotide excision repair, and the regulatory pathways and targets that play a key role in the process of HCC recurrence were analyzed to predict the possible regulatory mechanisms. The independent samples t-test was used for comparison of continuous data between two groups; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsFor the eukaryotic replication complex pathway, there were significant reductions in the protein expression levels of MCM2 (P=0.018), MCM3 (P=0.047), MCM4 (P=0.014), MCM5 (P=0.008), MCM6 (P=0.006), MCM7 (P=0.007), PCNA (P=0.019), RFC4 (P=0.002), RFC5 (P<0.001), and LIG1 (P=0.042); for the nucleotide excision repair pathway, there were significant reductions in the protein expression levels of PCNA (P=0.019), RFC4 (P=0.002), RFC5 (P<0.001), and LIG1 (P=0.042); for the base excision repair pathway, there were significant reductions in the protein expression levels of PCNA (P=0.019) and LIG1 (P=0.042) in the HCC recurrence group; for the mismatch repair pathway, there were significant reductions in the protein expression levels of MSH2 (P=0.026), MSH6 (P=0.006), RFC4 (P=0.002), RFC5 (P<0.001), PCNA (P=0.019), and LIG1 (P=0.042) in recurrent HCC tissue. The differentially expressed proteins were involved in the important components of MCM complex, DNA polymerase complex, ligase LIG1, long patch base shear repair complex (long patch BER), and DNA mismatch repair protein complex. The clinical sample validation analysis of important differentially expressed proteins regulated by DNA repair showed that except for MCM6 with a trend of reduction, the recurrence group also had significant reductions in the relative protein expression levels of MCM5 (P=0.008), MCM7 (P=0.007), RCF4 (P=0.002), RCF5 (P<0.001), and MSH6 (P=0.006). ConclusionThere are significant reductions or deletions of multiple complex protein components in the process of DNA repair during HCC recurrence.

AIM:To explore the roles and associations of hepatocyte nuclear factor 4 alpha(HNF4A)and mu-protocadherin(MUCDHL)in the kidney of diabetic mice.METHODS:(1)A cohort of six 12-week-old db/m mice and six db/db mice were selected and maintained on a standard diet until 16 weeks.The protein levels of fibronectin(FN),collagen type III(Col-III),E-cadherin,α-smooth muscle actin(α-SMA),HNF4A,Snail and MUCDHL in renal tissues were scrutinized using Western blot.Immunohistochemical staining was conducted to observe the distribution and expres-sion of FN,HNF4A and MUCDHL.(2)Mouse renal tubular epithelial cells(mRTEC)were cultured in vitro and catego-rized into groups:normal glucose(NG)group,high glucose(HG)group,overexpression control groups(NG+vector and HG+vector),overexpression groups(NG+OE-MUCDHL,HG+OE-MUCDHL,NG+OE-HNF4A and HG+OE-HNF4A),knockdown control groups(NG+control and HG+control),and knockdown groups(NG+si-MUCDHL,HG+si-MUCDHL,NG+si-HNF4A and HG+si-HNF4A).The relevant protein levels were also detected by Western blot.RESULTS:(1)In db/db group,elevated body weight,blood glucose and urine albumin-to-creatinine ratio(UACR)indicated significant re-nal injury.Compared with db/m group,the mice in db/db group exhibited increased expression of FN,Col-III,α-SMA and Snail,and decreased expression of E-cadherin,HNF4A and MUCDHL.MUCDHL was predominantly expressed in the apical membrane of renal tubular epithelial cells,FN in the tubular mesenchyme,and HNF4A in the plasma and nu-cleus of renal tubular cells.(2)In HG group,there was an up-regulation in the expression of fibrosis-related proteins and a down-regulation in the expression of E-cadherin,HNF4A and MUCDHL compared with NG group.Overexpression of MUCDHL led to a decrease in the expression of FN,Col-III,α-SMA and Snail proteins,an increase in the expression of E-cadherin and MUCDHL proteins,and unaltered expression of HNF4A.Knockdown of MUCDHL resulted in a reversal of the aforementioned effects,with HNF4A expression remaining unaltered.Overexpression of HNF4A led to an increased ex-pression of MUCDHL,and the expression changes of the remaining indicators were consistent with the overexpression of MUCDHL.Knockdown of HNF4A reversed the aforementioned effects.MUCDHL may represent a downstream target gene of HNF4A.CONCLUSION:The diminished expression of HNF4A and MUCDHL in the renal tubules of diabetic mice implies their involvement in the progression of renal fibrosis in diabetic kidney disease(DKD).HNF4A may potentially impede the progression of renal fibrosis in DKD by up-regulating the expression of MUCDHL.

Objective:To test the effectiveness of electrical stimulation of the median nerve (MNES) for relieving post-stroke cognitive impairment (PSCI) and explore the possible mechanism.Methods:Thirty patients with PSCI were randomly divided into a routine treatment group (the control group) and an MNES group, each of 15. Both groups were given routine rehabilitation treatment, including cognitive rehabilitation training, medications and acupuncture. The MNES group additionally received 30 minutes of MNES on their right hands every day, five times a week for six weeks. One electrode was positioned over the median nerve 2cm up from the rasceta of the right wrist. The other was on the muscles of the thenar eminence. Forty seconds of stimulation were applied with intervals of 20 seconds, for 30 min daily. Before and after 3 and 6 weeks of treatment, both groups were evaluated using the mini-mental state examination (MMSE), the Montreal cognitive assessment (MoCA), the modified Barthel index (MBI) and the Fugl-Meyer assessment (FMA). In another 15 patients oxyhemoglobin levels in the brain before and during the MNES were observed using near-infrared spectroscopy.Results:After 3 weeks of treatment, a significant improvement was observed in the average MMSE, FMA and MBI scores of both groups, and the average MoCA score of the observation group. Three weeks later, the average MMSE, FMA, MBI and MoCA scores of both groups had improved significantly compared with before the treatment, with the average MMSE and MoCA improvements in the MNES group significantly greater than the control group′s averages. After 6 weeks of treatment the significant improvements persisted in both groups. Both group′s average FMA scores had also improved significantly, as had the average MBI score of the control group. After 6 weeks of treatment, the observation group′s average time orientation, location orientation, language instant memory, attention, calculation and short-term memory in MMSE had all improved significantly along with visual space capacity, executive capacity, attention, language, orientation and memory in MoCA. The spectroscopic results showed significantly improved oxyhemoglobin concentration in the bilateral frontal lobes after the MNES.Conclusions:Electrical stimulation of the median nerve can help to improve cognition after a stroke. It increases oxyhemoglobin concentration in the bilateral frontal lobes.

The rapid mutation and widely spread of duck hepatitis A virus (DHAV) lead to the vast economic loss of the duck industry. To prepare and evaluate bivalent inactivated vaccine laboratory products of DHAV, 6 strains were screened from 201 DHAV-1 strains and 38 DHAV-3 strains by using serotype epidemiological analysis in most of the duck factory. Vaccine candidate strains were selected by ELD50 and LD50 tests in the 6 strains. Continuously passaged, the 5th passaged duck embryos bodies grinding fluid was selected as vaccine virus seeds. The virus seeds were treated with formaldehyde and water in oil in water (W/O/W) emulsions, making into three batches of two bivalent inactivated vaccine laboratory products. The safety test, antibody neutralization test, challenged protection and cross immune protection experiment suggested that the vaccines possessed good safety, and neutralizing antibodies were detected at 7th day and the challenged protection rate reached 90% to 100% at the 14th and 21st day. Moreover, immune duration of ducklings lasted more than five weeks. However, cross-immunity protection experiments with DHAV-SH and DHAV-FS only had 20%-30%. The two bivalent inactivated vaccine laboratory products of duck viral hepatitis were effective and reliable, providing a new method as well as a new product for DHAV prevention and control.
