Objective:
To investigate the mechanism of Yishen Tongluo Formula in ameliorating renal pyroptosis in diabetic nephropathy mice by regulating the toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-κB (NF-κB) signaling pathway.
Methods:
Sixty C57BL/6 male mice were randomly divided into control (10 mice) and intervention groups (50 mice) using random number table method. The diabetes nephropathy model was established by intraperitoneally injecting streptozotocin(50 mg/kg). After modeling, the intervention group was further divided into model, semaglutide (40 μg/kg), and high-, medium-, and low-dose Yishen Tongluo Formula groups (15.6, 7.8, and 3.9 g/kg, respectively) using random number table method. The high-, medium-, and low-dose Yishen Tongluo Formula groups were administered corresponding doses of medication by gavage, the semaglutide group received a subcutaneous injection of semaglutide injection, and the control group and model groups were administered distilled water by gavage for 12 consecutive weeks. Random blood glucose levels of mice in each group were monitored, and the 24-h urinary protein content was measured using biochemical method every 4 weeks; after treatment, the serum creatinine and urea nitrogen levels were measured using biochemical method. The weight of the kidneys was measured, and the renal index was calculated. Hematoxylin and eosin, periodic acid-Schiff, periodic Schiff-methenamine, and Masson staining were used to observe the pathological changes in renal tissue. An enzyme-linked immunosorbent assay was used to detect urinary β2-microglobulin (β2-MG), neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule-1 (KIM-1) levels. Western blotting and real-time fluorescence PCR were used to detect the relative protein and mRNA expression levels of nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3), Caspase-1, gasdermin D (GSDMD), interleukin-1β (IL-1β), and interleukin-18 (IL-18) in renal tissue. Immunohistochemistry was used to detect the proportion of protein staining area of the TLR4, MyD88, and NF-κB in renal tissue.
Results:
Compared with the control group, the random blood glucose, 24-h urinary protein, serum creatinine, urea nitrogen, and renal index of the model group increased, and the urine β2-MG, NGAL, and KIM-1 levels increased. The relative protein and mRNA expression levels of NLRP3, Caspase-1, GSDMD, IL-1β, and IL-18 in renal tissue increased, and the proportion of TLR4, MyD88, and NF-κB protein positive staining areas increased (P<0.05). Pathological changes such as glomerular hypertrophy were observed in the renal tissue of the model group. Compared with the model group, the Yishen Tongluo Formula high-dose group showed a decrease in random blood glucose after 12 weeks of treatment (P<0.05). The Yishen Tongluo Formula high- and medium-dose groups showed a decrease in 24-h urinary protein, creatinine, urea nitrogen, and renal index, as well as decreased β2-MG, NGAL, and KIM-1 levels. NLRP3, Caspase-1, GSDMD, IL-1 β, and IL-18 relative protein and mRNA expression levels were also reduced, and the proportion of TLR4, MyD88, and NF-κB protein positive staining areas was reduced (P<0.05). Pathological damage to renal tissue was ameliorated.
Conclusion
Yishen Tongluo Formula may exert protective renal effects by inhibiting renal pyroptosis and alleviating tubular interstitial injury in diabetic nephropathy mice by regulating the TLR4/MyD88/NF-κB signaling pathway.

ObjectiveTo investigate the effect and mechanism of Yishen Tongluo prescription in protecting mice from oxidative stress injury in diabetic kidney disease (DKD) via the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1)/NAD(P)H quinone oxidoreductase 1 (NQO1) signaling pathway. MethodsSpecific pathogen-free (SPF) male C57BL/6 mice were assigned into a control group (n=10) and a modeling group (n=50). The DKD model was established by intraperitoneal injection of streptozotocin. The mice in the modeling group were randomized into a model group, a semaglutide (40 μg·kg-1) group, and high-, medium-, and low-dose (18.2, 9.1, 4.55 g·kg-1, respectively) Yishen Tongluo prescription groups, with 10 mice in each group. The treatment lasted for 12 weeks. Blood glucose and 24-h urine protein levels were measured, and the kidney index (KI) was calculated. Serum levels of creatinine (SCr), blood urea nitrogen (BUN), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were assessed. The pathological changes in the renal tissue were evaluated by hematoxylin-eosin, periodic acid-Schiff, periodic acid-silver methenamine, and Masson’s trichrome staining. Enzyme-linked immunosorbent assay kits were used to measure the levels of β2-microglobulin (β2-MG), neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), liver fatty acid-binding protein (L-FABP), nitric oxide synthase (NOS), glutathione (GSH), total antioxidant capacity (T-AOC), and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Immunohistochemical staining was performed to examine the expression of Kelch-like ECH-associated protein 1 (Keap1) and malondialdehyde (MDA). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the mRNA and protein levels, respectively, of factors in the Nrf2/HO-1/NQO1 signaling pathway. ResultsCompared with the control group, the DKD model group showed rises in blood glucose, 24-h urine protein, KI, SCr, BUN, and ALT levels, along with glomerular hypertrophy, renal tubular dilation, thickened basement membrane, mesangial expansion, and collagen deposition. Additionally, the model group showed elevated levels of β2-MG, NGAL, KIM-1, L-FABP, NOS, and 8-OHdG, lowered levels of GSH and T-AOC, up-regulated expression of MDA and Keap1, and down-regulated expression of Nrf2, HO-1, NQO1, and glutamate-cysteine ligase catalytic subunit (GCLC) (P<0.05). Compared with the model group, the semaglutide group and the medium- and high-dose Yishen Tongluo prescription groups showed reductions in blood glucose, 24-h urine protein, KI, SCr, BUN, and ALT levels, along with alleviated pathological injuries in the renal tissue. In addition, the three groups showed lowered levels of β2-MG, NGAL, KIM-1, L-FABP, NOS, and 8-OHdG, elevated levels of GSH and T-AOC, down-regulated expression of MDA and Keap1, and up-regulated expression of Nrf2, HO-1, NQO1, and GCLC (P<0.05). ConclusionYishen Tongluo prescription exerts renoprotective effects in the mouse model of DKD by modulating the Nrf2/HO-1/NQO1 signaling pathway, mitigating oxidative stress, and reducing renal tubular injuries.

ObjectiveTo explore the effect and mechanism of the classic famous prescription Anmeidan (AMD) developed in the Qing Dynasty in regulating the hepatic neurotransmitters and circadian rhythm in the rat model of insomnia via the orexin-1 receptor (OX1R)/phosphatidylinositol-specific phospholipase Cβ-1 (PLCβ-1)/protein kinase Cα (PKCα)/extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway. MethodSixty SPF-grade SD rats were randomized into blank, model, suvorexant (30 mg·kg-1·d-1), and low-, medium-, and high-dose (4.55, 9.09, 18.09 g·kg-1·d-1, respectively) AMD groups, with 10 rats in each group. The rats in other groups except the blank group were modeled by intraperitoneal injection of p-chlorophenylalanine (PCPA) and administrated with corresponding drugs by gavage, and the blank group received an equal volume of normal saline. The general condition, body mass, and 24 h autonomic activity of each group were observed. The pathological changes of the liver tissue were observed by hematoxylin-eosin(HE)staining and Masson staining. The expression of gamma-aminobutyric acid (GABA), 5-hydroxytryptamine (5-HT), epinephrine (EPI), norepinephrine (NE), and acetylcholine (ACh) in the liver tissue was detected by enzyme-linked immunosorbent assay. The glutamate (Glu) expression in the liver tissue was detected by the biochemical method. The mRNA levels of biological clock genes Per1, Per2, Cry1, Cry2, Bmal1, and Bmal2 in the liver were determined by Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR). The protein and mRNA levels of factors in the OX1R/PLCβ-1/PKCα/ERK1/2 signaling pathway in the liver were determined by Western blot and Real-time PCR, respectively. ResultCompared with the blank group, the modeling decreased the body mass (P<0.05, P<0.01) and caused mania and disturbed resting rhythms (P<0.01), hepatic muscle fiber fracture, and edema with inflammatory cell infiltration. In addition, the modeling decreased the GABA, 5-HT, EPI, NE, and ACh content, increased Glu content (P<0.01), down-regulated the mRNA levels of Per1, Per2, Cry1, and Cry2 (P<0.01), up-regulated the mRNA levels of Bmal1 and Bmal2 (P<0.01), and promoted the expression of OX1R, PLCβ-1, PKCα, and ERK1/2 at both protein and mRNA levels (P<0.01). Compared with the model group, suvorexant and AMD increased the body mass (P<0.05, P<0.01), alleviated the mania, and increased the resting time and frequency (P<0.05, P<0.01). Moreover, the medications elevated the levels of GABA, 5-HT, EPI, NE, and ACh, lowered the Glu level, up-regulated the mRNA levels of Per1, Per2, Cry1, and Cry2 (P<0.05, P<0.01), down-regulated the mRNA levels of Bmal1 and Bmal2, and inhibited the expression of OX1R, PLCβ-1, PKCα, and ERK1/2 at both mRNA and protein levels (P<0.05, P<0.01). ConclusionAMD can regulate hepatic neurotransmitters and improve circadian rhythm in insomniac rats by inhibiting the OX1R/PLCβ-1/PKCα/ERK1/2 signaling pathway, and high-dose AMD demonstrated the strongest effect.

Objective:To summarize the clinical features and postoperative efficacy of patients with oval window atresia accompanied by facial nerve aberration.Methods:The clinical data of patients with congenital middle ear malformation with facial nerve aberration admitted to our hospital from January 2015 to March 2023 were retrospectively analyzed. There were 97 cases (133 ears) in total. Among them, 39 patients (44 ears) had complete follow-up data, including 27 male patients and 12 females, aged 7-48 years old, with an average age of 17.8 years old. Of these, 14 cases (16 ears) were patients combined with facial nerve aberration, and 25 cases (28 ears) were without facial nerve aberration. The results of imaging examination, pure-tone audiometry, selection of surgical strategy, intraoperative findings and postoperative hearing improvement were summarized and analyzed. The malformations of malleus, incus, stapes, oval window and facial nerve were recorded. Prism 9 software was used to statistically analyze the mean bone conductance and air-bone gap of patients before and after surgery.Results:All the 14 patients (16 ears) with middle ear malformation accompanied by facial nerve aberration and oval window atresia showed poor hearing and no facial palsy since childhood. High resolution CT (HRCT) examination of temporal bone, pure tone audiometry and Gelle test were performed before surgery. The malformations of malleus, incus, stapes, oval window and facial nerve were recorded. Preoperative high-resolution CT (HRCT) examination of temporal bone found 12 ears with 4 or more deformities, accounting for 75.00%, in the group of patients with facial nerve malformation. The preoperative average bone conductive threshold was (15.3±10.4) dB and the average air-bone gap was (46.3±10.6) dB in pure-tone audiometry (0.5, 1, 2, 4kHz). According to the different degrees of facial nerve and ossicle malformation, we performed three different hearing reconstruction strategies for the 14 patients (16 ears) with facial nerve aberration and oval window atresia, including 7 ears of incus bypass artificial stape implantation, 7 ears of Malleostapedotomy (MS) and 2 ears of Malleus-cochlear-prothesis (MCP). After 3 months to 18 months of follow-up, all patients showed no facial paralysis. The postoperative mean bone conductive threshold was (15.7±7.9) dB and air-bone gap was (19.8±8.5) dB. There were significant differences in mean air-bone gap before and after operation ( t=7.766, P<0.05), and there was no significant difference between the mean bone conductive threshold before and after surgery ( t=0.225, P=0.824). There was no significant difference of mean reduction of air-bone gap between patients with and without facial nerve aberration ( t=1.412, P=0.165). There was no significant difference between the three hearing reconstruction strategies. There was no significant displacement of the Piston examined by U-HRCT. Conclusion:For patients of middle ear malformation whose facial nerve cover the oval window partially, incus bypass artificial stape implantation or Malleostapedotomy (MS) can be selected according to the specific condition of auditory ossis malformation, and for patients whose facial nerve completely covers the oval window area, Malleus-cochlear-prothesis (MCP) can be selected. Three types of stapes surgery are safe and reliable for patients with oval window atresia accompanied by facial nerve aberration. There was no significant difference in efficacy between them. Preoperative HRCT assessment of middle ear malformation is effective. There is no significant difference of surgical effect with or without facial nerve aberration. The U-HRCT can be used to evaluate the middle ear malformation before surgery and the Piston implantation status after surgery. Due to the risks of surgery, those who do not want to undergo surgery can choose artificial hearing AIDS, such as hearing aid, vibrating soundbridge, bone bridge or bone-anchored hearing aid.

Interpreting genes of interest is essential for identifying molecular mechanisms, but acquiring such information typically involves tedious manual retrieval. To streamline this process, the fanyi package offers tools to retrieve gene information from sources like National Center for Biotechnology Information (NCBI), significantly enhancing accessibility. Additionally, understanding the latest research advancements and sharing achievements are crucial for junior researchers. However, language barriers often restrict knowledge absorption and career development. To address these challenges, we developed the fanyi package, which leverages artificial intelligence (AI)-driven online translation services to accurately translate among multiple languages. This dual functionality allows researchers to quickly capture and comprehend information, promotes a multilingual environment, and fosters innovation in academic community. Meanwhile, the translation functions are versatile and applicable beyond biomedicine research to other domains as well. The fanyi package is freely available at https://github.com/YuLab-SMU/fanyi.

Objective To investigate the prevalence and distribution of pre-diabetes and diabetes mellitus in Han population aged over 60 years in Urumqi. Methods The physical examination and 75 g oral glucose tolerance test (OGTT) were performed in 2210 people, including 1231 elderly people aged over 60 years (old age group) and 951 people aged 40-59 years (middle age group). The diagnosis of diabetes mellitus was established according to WHO criteria in 1999. Results In Han ethnic people, the prevalence rates of diabetes mellitus and pre-diabetes were 32.2% and 29.0% respectively in old age group, and were significantly higher than in middle age group ( 12.3% and 20.9%,x2= 192.62, P<0.05). The prevalence rates of impaired glucose tolerance (IGT) were higher in old age group than in middle age people (21.6% vs. 13.9%, x2 = 20.97, P<0.05), but there was no significant difference in the prevalence rate of impaired fasting glucose (IFG) between the two groups. The prevalence rate of metabolism syndrome (MS) was higher in old age group than in middle age group (52.2% vs. 33.7%, x2 =73.77, P<0.05). The multivariable analysis showed that hypertriglyceridemia, hypertension, family history of diabetes mellitus were risk factors for development of diabetes mellitus in elderly Han population (x2 =44.34, P<0.05). Conclusions The prevalence rates of diabetes and pre-diabetes are considerably high in the current state. It should be strengthened to prevent and treat diabetes mellitus and pre-diabetes in Urumqi Han population,especially in residents aged over 60 years.
