Distribution of pathological types and epidemiological characteristics based on kidney biopsy in Northwest China

The spectrum of biopsy-confirmed kidney disease varies with regions and periods. We describe the distribution of pathological types and epidemiological characteristics of kidney diseases in Northwest China due to regional differences in geographical environment, social economy, and dietary habits. Methods: Kidney biopsy cases from 2005 to 2020 in Xijing Hospital were retrospectively analyzed. Pathological characteristics of patients in different periods were analyzed using the t test or chi-square test. Joinpoint regression was used to analyze trends in pathological types and disease spectrum. Results: A total of 10,528 eligible patients were included. Primary glomerular disease (PGD) accounted for the majority of the cases and exhibited an obvious downward trend, whereas secondary glomerular disease (SGD) showed an obvious upward trend. Among PGD, immunoglobulin A nephropathy (IgAN) remained the most common pathological type, and the detection rate of membranous nephropathy (MN) was significantly increased. Among SGD, Henoch-Schönlein purpura nephritis (HSPN) was the most common pathological type and may present a significant characteristic of Northwest China. Diabetic nephropathy (DN) exhibited the most obvious upward trend in the whole process, whereas the fastest growth since 2012 was in hypertensive nephropathy. Conclusion: The proportion of SGD increased whereas PGD declined. IgAN remained the most common PGD, and HSPN was the most common SGD. MN and DN showed the most obvious upward trend among PGD and SGD, respectively. Changes in the spectrum of kidney disease, especially the constituent ratio of SGD, pose a great challenge to public health.

Inhibitory effects of naringenin on the activation of hepatic stellate cells through activating the apoptosis signal / 中国药房

OBJECTIVE To study the inhibitory effects and possible mechanism of naringenin on the activation of hepatic stellate cells. METHODS Using human hepatocytes LO2 as reference， based on drug intervention concentration screened by MTT assay， the effects of naringenin （Western blot assay and trypan blue staining test in 10， 20， 40 μmol/L， immunofluorescence assay in 40 μmol/L） on the expressions of liver fibrosis markers protein （collagen Ⅰ， α-SMA） and mRNA （α1-pro collagen Ⅰ， α-SMA） in human hepatic stellate cells LX2， and the expressions of cell apoptosis and apoptosis-related proteins （Bcl-2， Bax， cleaved caspase-3） were investigated. The apoptosis agents （Z-VAD-FMK， FMK）， ferroptosis pathway inhibitor ferrostatin-1， and programmed death pathway inhibitor necrostatin-1 were used to verify the mechanism of the above effects. RESULTS The naringenin could significantly down-regulate protein expressions of collagen Ⅰ （except for naringenin 10 μmol/L） and α-SMA， mRNA expressions of α1-pro collagen Ⅰ （except for naringenin 10 μmol/L） and α-SMA （P＜0.05）； it also induced LX2 cell apoptosis and increased its apoptotic ratio， down-regulated the protein expression of Bcl-2 while up-regulated the protein expressions of Bax （except for naringenin 10 μmol/L） and cleaved caspase-3 （except for naringenin 10 μmol/L）. FMK could reverse above effects of naringenin on LX2 cells （P＜0.05）. CONCLUSIONS Naringenin can inhibit the activation of hepatic stellate cells LX2 through activating the cell apoptosis signal， which plays ameliorative role in liver fibrosis.

OB JECTIVE To explore the construction of system of pharmacoeconomic evaluation fo r Chinese patent medicine in preventing and treating major chronic diseases. METHODS The problems in pharmacoeconomic evaluation of Chinese patent medicine for preventing and treating major chronic diseases were analyzed. Based on the problem ，the pharmacoeconomic theory ， tools and methods that can be used to systematically evaluate the prevention and treatment of major chronic diseases by Chinese patent medicine were explored to build the relevant pharmacoeconomic evaluation system. RESULTS & CONCLUSIONS Traditional Chinese medicine shows the advantages in the prevention and treatment of major chronic diseases. This unique advantage needed to be explored ，reflected and proved in the pharmacoeconomic evaluation. The pharmacoeconomic evaluation of Chinese patent medicine had made some progress in recent years. However ，there were still deficiencies of theory and methodology in the pharmacoeconomic evaluation for the advantages of Chinese patent medicine in preventing and treating major chronic diseases. It was difficult to truly and comprehensively reflect the value of Chinese patent medicine by simply applying the economic evaluation indicators and technologies of chemical medicine. It is necessary to focus on the unique pharmacoeconomic attributes of Chinese patent medicine ，excavate the economic value indicators of Chinese patent medicine for “preventive treatment of disease ” and playing the self-regulation role of human body ，comprehensively consider the pharmacoeconomic particularity of Chinese patent medicine in respects of research design ，research angle ，target population ，intervention measures and control selection ，research time limit and evaluation method ，etc. Through the use of system modeling ，real-world research and the establishment of Chinese medicinal quality of life scale that reflects the characteristics of TCM ，the economic value of Chinese patent medicine in the prevention and treatmen t of major chronic diseases is reflected comprehensively，so as to reflect the advantage of Chinese patent medicine in preventing and treating major chronic diseases.

Ruscogenin alleviates LPS-triggered pulmonary endothelial barrier dysfunction through targeting NMMHC IIA to modulate TLR4 signaling

Pulmonary endothelial barrier dysfunction is a hallmark of clinical pulmonary edema and contributes to the development of acute lung injury (ALI). Here we reported that ruscogenin (RUS), an effective steroidal sapogenin of Radix Ophiopogon japonicus, attenuated lipopolysaccharides (LPS)-induced pulmonary endothelial barrier disruption through mediating non-muscle myosin heavy chain IIA (NMMHC IIA)‒Toll-like receptor 4 (TLR4) interactions. By in vivo and in vitro experiments, we observed that RUS administration significantly ameliorated LPS-triggered pulmonary endothelial barrier dysfunction and ALI. Moreover, we identified that RUS directly targeted NMMHC IIA on its N-terminal and head domain by serial affinity chromatography, molecular docking, biolayer interferometry, and microscale thermophoresis analyses. Downregulation of endothelial NMMHC IIA expression in vivo and in vitro abolished the protective effect of RUS. It was also observed that NMMHC IIA was dissociated from TLR4 and then activating TLR4 downstream Src/vascular endothelial cadherin (VE-cadherin) signaling in pulmonary vascular endothelial cells after LPS treatment, which could be restored by RUS. Collectively, these findings provide pharmacological evidence showing that RUS attenuates LPS-induced pulmonary endothelial barrier dysfunction by inhibiting TLR4/Src/VE-cadherin pathway through targeting NMMHC IIA and mediating NMMHC IIA‒TLR4 interactions.

He-Wei Granule enhances anti-tumor activity of cyclophosphamide by changing tumor microenvironment / 中草药·英文版

Objective: He-Wei Granule (HWKL) is a modern product derived from the modified formulation of traditional Chinese medicine Banxia Xiexin Decoction (BXD), which remarkedly enhanced the anti-proliferation activity of cyclophosphamide (CTX) on HepG2 and SGC-7901 cell lines in vitro in our previous research. The aim of the study was to investigate the synergistic effects of HWKL and CTX using a transplanted H22 hepatocellular carcinoma mouse model. Methods: The CTX-toxic-reducing efficacy of HWKL was evaluated by hematology indexes, organ indexes and marrow DNA detection. To investigate the underlying mechanisms, histopathology test, immunohistochemistry test and TUNEL staining were conducted. The efficacy of HWKL on the micro-vessel density (MVD) in tumor tissue was also evaluated by measuring CD34 level. Results: High dose HWKL (6.75 g/kg) markedly attenuated CTX-induced hepatotoxicity and myelosuppression while significantly enhanced CTX anticancer efficacy in vivo. Further mechanism investigation suggested that high dose HWKL significantly increased cleaved Caspase 3 level and promoted apoptosis in tumor tissue by up-regulating Bax expression and down-regulating Bcl-2 and FasL expressions. Compared with CTX alone group, the decrease in LC-3B and Beclin 1 levels suggested that the autophagy in H22 carcinoma was significantly inhibited with addition of high dose HWKL. ELISA assay results indicated that the autophagy inhibition was achieved by decreasing p53 expression, blocking PI3K/AKT/mTOR pathway and recovering Th1/Th2 cytokine balance. In addition, CD34 and EGFR immunohistochemistry assay suggest that high dose HWKL could significantly decrease micro-vessel density (MVD) and inhibit angiogenesis in H22 carcinoma. Conclusion: It can be concluded that high-dose HWKL enhanced CTX efficacy by promoting apoptosis, inhibiting autophagy and angiogenesis in tumor tissue while significantly alleviated CTX-induced toxicity, and could be applied along with CTX in clinical treatment as a supplement agent.

Da Chaihutang Inhibits Hepatocellular Carcinoma by Regulating p38 MAPK/IL-6/STAT3 Signaling Pathway / 中国实验方剂学杂志

ObjectiveThis study aims to investigate the efficacy and underlying mechanism of Da Chaihutang （DCHT） in treating hepatocellular carcinoma （HCC） in vitro and in vivo. MethodWe employed methyl thiazolyl tetrazolium （MTT） assay and crystal violet staining to observe the proliferation of Hepa1-6 liver cancer cells treated with DCHT at different doses （0， 125， 250， 500， 1 000 mg·L-1） for different time periods （1， 2， 4， 8 days）. The orthotopic liver cancer model was established by injection of 1×106 Hepa1-6 cells into mouse， and then the model mice were randomly assigned into six groups： blank， model， DCHT （0.21， 0.625， 1.875 g·kg-1， ig， qd）， and positive control （5-fluorouracil， 25 mg·kg-1， ip， qod）. After 14 days of administration， the mice were sacrificed， and the liver samples were collected and fixed in 4% paraformaldehyde for hematoxylin-eosin （HE） staining. The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， Cytoscape 3.7.2， STRING， and DAVID were used for the searching of the key targets of DCHT in treating HCC， the construction of protein-protein interaction （PPI） network， and the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment. Quantitative real-time PCR was performed to determine the mRNA level of interleukin-6 （IL-6） in Hepa1-6 cells and liver tissue. Western blotting was employed to measure the protein levels of the proteins involved in the mitogen-activated protein kinase （MAPK） and signal transducers and activators of transcription 3 （STAT3） signaling pathways. ResultDCHT （500， 1 000 mg·L-1） treatment for 4 and 8 days inhibited the proliferation of Hepa1-6 cells in a dose- and time-dependent manner （P<0.05）. The in vivo assay showed that DCHT （high dose， 1.875 g·kg-1） treatment for 14 days led to high differentiation and unobvious heterogeneity of HCC cells and small necrotic area compared with the model group. Network pharmacology analysis predicted that the potential targets of DCHT in the treatment of HCC were mainly the inflammation cytokines such as IL-6， interleukin-1β （IL-1β）， and tumor necrosis factor-alpha （TNF-α） in HCC microenvironment. The potential signaling pathways involved in the treatment were mainly associated with HCC growth and differentiation， including MAPK and STAT3 signaling pathways. Compared with the blank group， DCHT （1 000 mg·L-1） treatment for 1， 2， 4， and 8 days down-regulated the mRNA level of IL-6 in Hepa1-6 cells （P<0.05）. Similar results were observed in the livers of mice treated with DCHT （0.625， 1.875 g·kg-1）. The in vitro assay demonstrated that DCHT （1 000 mg·L-1） treatment for 4 and 8 days and DCHT （500， 1 000 mg·L-1） treatment inhibited the phosphorylation of extracellular signal-regulated kinases 1/2 （ERK1/2）， c-Jun NH2-terminal kinase/stress-activated protein kinase （JNK）， p38 MAPK， and STAT3 in a dose- and time-dependent manner （P<0.05）. The in vivo assay showed that DCHT （0.625 and 1.875 g·kg-1） treatment only inhibited the phosphorylation of p38 MAPK and STAT3 （P<0.05）. ConclusionThe present study indicates that DCHT can inhibit liver cancer cell proliferation by regulating p38 MAPK/IL-6/STAT3 signaling pathway.

Clinical characteristics and risk factors for mortality in cancer patients with COVID-19 / 医学前沿

Patients with cancer are at increased risk of severe infections. From a cohort including 3060 patients with confirmed COVID-19, 109 (3.4%) cancer patients were included in this study. Among them, 23 (21.1%) patients died in the hospital. Cancer patients, especially those with hematological malignancies (41.6%), urinary carcinoma (35.7%), malignancies of the digestive system (33.3%), gynecological malignancies (20%), and lung cancer (14.3%), had a much higher mortality than patients without cancer. A total of 19 (17.4%) cancer patients were infected in the hospital. The clinical characteristics of deceased cancer patients were compared with those of recovered cancer patients. Multivariate Cox regression analysis indicated that a Nutritional Risk Screening (NRS2002) score ⩾ 3 (adjusted hazard ratio (HR) 11.00; 95% confidence interval (CI) 4.60-26.32; P < 0.001), high-risk type (adjusted HR 18.81; 95% CI 4.21-83.93; P < 0.001), tumor stage IV (adjusted HR 4.26; 95% CI 2.34-7.75; P < 0.001), and recent adjuvant therapy (< 1 month) (adjusted HR 3.16; 95% CI 1.75-5.70; P < 0.01) were independent risk factors for in-hospital death after adjusting for age, comorbidities, D-dimer, and lymphocyte count. In conclusion, cancer patients showed a higher risk of COVID-19 infection with a poorer prognosis than patients without cancer. Cancer patients with high-risk tumor, NRS2002 score ⩾ 3, advanced tumor stage, and recent adjuvant therapy (< 1 month) may have high risk of mortality.

Role of retinal microglia-mediated parainflammation in age-related macular degeneration / 中华实验眼科杂志

Age-related macular degeneration (AMD) is a disease caused by multiple factors such as age, genetics and environmental risks.Inflammation plays an important role in the pathogenesis of AMD.Between the basal level and the classic inflammatory response, the parainflammation plays an important role in maintaining tissue homeostasis.The dysregulated parainflammation is manifested as uncontrollable chronic inflammation.In recent years, a large number of studies have focused on the contribution of chronic non-resolving inflammation to the development of AMD, in which microglial dysfunction plays a significant part.The abnormal activation of microglia caused by various factors can lead to the disorder of the parainflammation.The causes and results of retinal microglial dysfunction were reviewed in this article, so as to focus on dysregulated parainflammation in AMD.
