Research progress in targeting autophagy of traditional Chinese medicine and natural compounds to regulate atherosclerosis / 中国中药杂志

Atherosclerosis(AS) is the common pathological basis of many ischemic cardiovascular diseases, and its formation process involves various aspects such as vascular endothelial injury and platelet activation. Vascular endothelial injury is the initiating factor of AS plaque. Monocytes are recruited to differentiate into macrophages at the damaged endothelial cells, which absorb oxidized low-density lipoprotein(ox-LDL) and slowly transform into foam cells. Smooth muscle cells(SMCs) proliferate and migrate continuously. As the only cell producing interstitial collagen fibers in the fibrous cap, SMCs largely determine whether the plaque ruptured or not. The amplifying inflammatory response during the formation of AS recruits platelets to adhere to the damaged area of vascular endothelium and stimulates excessive platelet aggregation. Autophagy activity is associated with vascular lesions and abnormal platelet activation, and excessive autophagy is considered to be a negative factor for plaque stability. Therefore, precise regulation of different types of vascular autophagy and platelet autophagy to treat AS may provide a new therapeutic perspective for the prevention and treatment of atherosclerotic ischemic cardiovascular disease. Currently, treatment strategies for AS still focus on lowering lipid levels with high-intensity statins, which often cause significant side effects. Therefore, the development of safer and more effective drugs and treatment modes is the focus of current research. Traditional Chinese medicine and natural compounds have the potential to treat AS by targeted autophagy, and have been playing an increasingly important role in the prevention and treatment of cardiovascular diseases in China. This paper summarizes the experimental studies on different vascular cell types and platelet autophagy in AS, and sums up the published research results on targeted autophagy of traditional Chinese medicine and natural plant compounds to regulate AS, providing new ideas for further research.

Objective:To observe the effect of Yangxin Tongmaifang （YXTM） on endogenous metabolites in the myocardial tissue of rats with coronary heart disease due to blood stasis based on the metabolomics approach， and to explore its mechanism in the treatment of heart blood stasis syndrome. Method:A rat model of chronic myocardial ischemia due to heart blood stasis was established via the high-fat diet combined with intragastric administration of vitamin D₃ and subcutaneous injection of isoproterenol （ISO）， followed by the intervention with YXTM. The metabolites in the myocardial tissues of rats in the normal group （<italic>n</italic>=8）， model group （<italic>n</italic>=8）， and YXTM group （<italic>n</italic>=8） were detected by ultra-high performance liquid chromatography coupled to high resolution mass spectrometry. The high-throughput metabolomics data were then subjected to multivariate statistical analysis using SIMCA 14.1， and the related metabolic pathways were analyzed with MetaboAnalyst. Result:The myocardial sample points of rats in the three groups were located in different areas of the elliptical confidence interval. The normal group and the model group were completely separated. There existed some crossovers and overlaps between the YXTM group and the normal group. The heart blood stasis syndrome model was proved successfully replicated from the perspective of metabolic profiling， and YXTM had the potential to promote the body to return to a normal state. After the intervention with YXTM， six differential metabolites changed significantly. Such metabolic pathways as valine， leucine， and isoleucine biosynthesis， pantothenate and coenzyme A （CoA） biosynthesis， valine， leucine， and isoleucine degradation， biosynthesis of aminoacyl-transfer RNA synthetases， and purine metabolism were involved. Conclusion:The therapeutic effect of YXTM on heart blood stasis syndrome in rats is related to the improved levels of myocardial endogenous metabolites， and its mechanism involves phospholipid metabolism， amino acid metabolism， energy metabolism， inflammatory response， and platelet activation and aggregation.

Air conditioning condition of observation hotels for COVID-19 prevention and control / 上海预防医学

Objective:To investigate the hygienic condition and maintenance management of air conditioners in observation hotels， and give suggestions on reducing the risk of COVID-19 transmission from the daily use. Methods:This study selected 11 observation hotels chosen by government and 3 observation hotels chosen by large companies in Minhang District. The types and sanitary conditions of the air conditioning system were revealed through the daily supervision. Hotel staffs’ knowledge of air conditioning system and their mastery of how to use and maintain air conditioning system were surveyed through questionnaire. Results:Survey of air conditioning types showed that in 14 hotels， 12 were distributed air conditioning systems and 2 were semi-centralized air conditioning systems （including fresh air systems）. The investigation found that there was dust accumulation in the fresh air ducts in one hotel guest room， dust accumulation in the filter screen of fresh air intake in one hotel， and the sanitary problem of condensate water （without centralized discharge） in two hotels. All of 14 hotels had daily cleaning and disinfection records， but they were not perfect. The hotel health management personnel’ awareness rate of air conditioning was low， although they had a positive attitude towards the cleaning and disinfection of the air conditioning system. They could do the active entrusted testing， cleaning and disinfection of the air conditioning systems. Conclusion:The air conditioning systems of some hotels have hygiene problems， and hotel health management personnel are lack of knowledge of standard operation and maintenance of air conditioning systems. The air conditioning systems of observation hotel should be cleaned and disinfected before use. At the same time， it is necessary to strengthen the training of hotel health management personnel on the use and maintenance of air conditioning systems. So the transmission of the COVID-19 through air conditioning systems can be effectively prevented.

Objective To investigate the expression of semaphorin 3A (Sema3A) and its receptor neuropilin-1 (NRP-1) in gastric cancer and its correlation with microvessel density (MVD), and then to explore the effect of recombinant human Sema3A on angiogenesis of gastric cancer and the associated mechanisms. Methods Forty cases of gastric cancer tissues and its corresponding adjacent normal tissues were used to detecte the expression of Sema3A, NRP-1 and MVD in tissues by immunohistochemistry method . The expression level of Sema3A in serum of gastric cancer patient group and normal control group were measured by Enzyme-linked immuno-sorbent assay (ELISA). Western blotting was used to detect the expression of Sema3A and NRP-1 in five gastric cancer cell lines (MGC-803,HGC-27,MKN-28,SGC-7901,MKN-45) and human gastric mucosal epithelial cell (GES-1). Transwell chamber was used to construct non-contact in vitro co-culture system, in which the effects of different concentrations of recombinant human Sema3A on angiogenesis in gastric cancer were analyzed by tube formation assay preliminarily. The expression levels of vascular endothelial growth factor receptor 2 (VEGFR2) and NRP-1 in co-culture system were detected by Western blotting. Results The expression levels of Sema3A in gastric cancer tissues, cell lines and patient serum were significantly lower than that in the control group(P<0. 05), while the expression of NRP-1 in gastric cancer tissues and MKN-28 cells was significantly increased, and both of them were associated with TNM staging of gastric cancer (P < 0. 05) . In vitro co-culture system, The tube forming abilities of human umbilical vein endothelial cell (HUVEC) were decreased in recombinant human Sema3A treated group, and this phenomenon was concentration dependent. The expression of VEGFR2 protein was down-regulated by recombinant human Sema3A. Conclusion The expression of Sema3A was decreased in gastric cancer tissues, cell lines and patient serum, and negatively correlated with microvessel density. The recombinant human Sema3A could inhibit the angiogenesis of gastric cancer in vitro, which may be related to down-regulation of VEGFR2 protein expression.

Inhibitory Effect and Mechanism of Yiqi Jianpi Huayu Recipe Combined with 5-FU on Gastric Cancer / 中国实验方剂学杂志

Objective::To observe the synergistic effect and mechanism of Yiqi Jianpi Huayu (YQJPHY) recipe combined with 5-fluorouracil (5-FU) on inhibiting gastric cancer growth, and investigate its possible mechanism through polarization direction of tumor-associated macrophages (TAMs) in tumor micro-environment. Method::A total of forty 615 mice were randomly divided into four groups including control group, YQJPHY(25 g·kg-1) group, 5-FU (25 mg·kg-1) group and combined group (YQJPHY plus 5-FU), with 10 mice in each group. The gastric cancer transplantation model was induced by axillary inoculation of MFC gastric cancer cells. Changes in tumor pathology were observed with hematoxylin-eosin staining (HE) method. The contents of M1 and M2 TAMs in tumor tissues were determined with flow cytometry, while the expression of CD206 in tumor was observed with immunohistochemistry. The mRNA expressions of TAM-related genes including interleukin-1β(IL-1β), interleukin-12(IL-12), tumor necrosis factor-α(TNF-α), arginase-1(Arg1), and chitinase 3-like 3(Ym1) were detected by using quantitative real-time polymerase chain reaction (Real-time PCR). Furthermore, the mRNA and protein expressions of epithelial-mesenchymal transition (EMT) related epithelial calcium adhesion protein(E-cadherin), nervous calcium adhesion protein(N-cadherin), Zinc finger transcription factor Slug, Snail and Waveform protein (Vimentin) were detected with Real-time PCR and Western blot, respectively. Result::The gastric cancer cells in tumors were distributed in nest and/or flaky shape, with fibroblastic connective tissue reaction and inflammatory cells infiltrated in interstitium. Coagulative necrosis of tumor was observed in various treatment groups. The amount of residual cancer cells in mouse was as follows from largest to smallest: control group>YQJPHY group>5-FU group>combined group. Immunohistochemical studies showed that all treatment groups can reduce the expression of CD206 in the tumor, and the effect was most obvious in the combined group. The contents of M2-TAM in all treatment groups were lower than those in control group(P<0.05, P<0.01), and the most significant difference in the content of M2-TAMs was shown between the control group and the combined group. The contents of M1 TAMs were increased in YQJPHY and combined groups(P<0.05, P<0.01), with the largest incremental range in YQJPHY group. The expressions of Arg1 and Ym1 in YQJPHY and combined groups were lower, while IL-1β, TNF-α and IL-12 levels were higher than those in control group(P<0.05). The mRNA expressions of IL-1β, IL-12 and TNF-α in the combined group were significantly higher, while Arg1 and Ym1 mRNA expression levels were lower than those in the 5-FU group(P<0.05). As compared with the control group, the mRNA and protein expression levels of E-cadherin were up-regulated(P<0.05), while the mRNA expression levels of N-cadherin and Vimentin were down-regulation in the YQJPHY group (P<0.05), E-cadherin mRNA and protein expression levels were up-regulated, while N-cadherin, Slug, Snail, Vimentin mRNA expression as well as N-cadherin and Slug protein expression levels were down-regulated in the combined group(P<0.05). As compared with the 5-FU group, the mRNA and protein expression levels of E-cadherin were up-regulated(P<0.05), while the mRNA and protein expression levels of N-cadherin, Slug and Vimentin were down-regulated in the combined group(P<0.05). Conclusion::YQJPHY has an inhibitory effect on the growth of gastric cancer, and after being combined with 5-FU, it has a good synergistic effect on inhibiting the growth of gastric cancer and decreasing EMT. The mechanism may be related to promoting the conversion from M2-TAMs to M1-TAMs in gastric tumor micro-environment.

Pancreatic fistula after pancreaticoduodenectomy: Risk factors and preventive strategies

Purpose: Postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD) is a worrisome and life-threatening complication. This study aimed to investigate the risk factors and preventive strategies for POPF after PD. Materials and Methods: We retrospectively reviewed 301 consecutive patients who underwent PD at our hospitals between January 2011 and December 2017. We analyzed the pancreatic fistula rate according to the clinical characteristics, pathologic and laboratory findings, and the anastomotic methods and summarized the prevention measures. Results: Postoperative morbidities included pancreatic leakage in 10.30% (31/301), delayed gastric emptying in 22.92% (69/301), abdominal infection in 6.98% (21/301), post-PD hemorrhage in 4.65% (14/301), and bile leakage in 4.98% (15/301), and the mortality rate was 2.33% (7/301). POPF was the most prominent factor for preoperative morbidity. Significant risk factors for pancreatic fistula were a soft pancreas, small pancreatic duct, tumor location, and interrupted anastomosis. Of these, soft texture, pancreatic duct <4 mm, and end-to-end anastomosis through hand suture closure were independent risk factors on multivariate analysis, while interrupted anastomosis, internal stent, and somatostatin use were risk factors in the high-risk pancreas subgroup. Conclusions: Our study demonstrated that pancreatic fistula is related to a soft texture and small pancreatic duct. The surgeon must consider these risk factors when performing PD. Thus, we propose a risk- and indication-adapted choice of anastomosis or an individualized approach for the pancreatic remnant to reduce the pancreatic fistula rate

The aim of this paper was to screen out relevant genes of geniposide-induced hepatotoxicity based on genomics,in order to provide a scientific basis for the non-clinical evaluation of drugs containing Gardeniae Fructus and geniposide. Fifty-five SD rats were randomly divided into normal control group,24 h group and 72 h group. The changes of appearance,behavior and weight of rats were observed after administration by gavage for 3 days. The activities of ALT and AST were detected. Molecular mechanism of geniposideinduced hepatotoxicity was investigated by Affymetrix miRNA 4. 0 and Affymetrix Rat Gene 2. 0 to examine the gene expression levels in Sprague-Dawley rat livers at 24 h and 72 h after administration of overdose-geniposide( 300 mg·kg-1 daily),and then verified by Realtime quantitative PCR. Compared with the normal control group,the activities of ALT and AST were markedly increased. In addition,experimental results indicated that 324 genes were differentially expressed,among which 259 were up-regulated and 65 down-regulated.Nine candidate genes were verified by qRT-PCR,including Bcl2,Il1 b,Tpm3,MMP2,Col1α1,Ifit1,Aldob,Nr0 b2,Cyp2 c23. And Bcl2,Col1α1,Aldob,Nr0 b2 and Cyp2 c23 were found to be correlated with geniposide-induced hepatotoxicity. This study provides an important clue for mechanism of geniposide-induced hepatotoxicity.

Plasma Macrophage Migration Inhibitory Factor and CCL3 as Potential Biomarkers for Distinguishing Patients with Nasopharyngeal Carcinoma from High-Risk Individuals Who Have Positive Epstein-Barr Virus Capsid Antigen-Specific IgA / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: The purpose of this study was to identify novel plasma biomarkers for distinguishing nasopharyngeal carcinoma (NPC) patients from healthy individuals who have positive Epstein-Barr virus (EBV) viral capsid antigen (VCA-IgA). MATERIALS AND METHODS: One hundred seventy-four plasma cytokines were analyzed by a Cytokine Array in eight healthy individuals with positive EBV VCA-IgA and eight patients with NPC. Real-time polymerase chain reaction, Western blotting, enzyme-linked immunosorbent assay (ELISA), and immunohistochemistry were employed to detect the expression levels of macrophage migration inhibitory factor (MIF) and CC chemokine ligand 3 (CCL3) in NPC cell lines and tumor tissues. Plasma MIF and CCL3 were measured by ELISA in 138 NPC patients, 127 EBV VCA-IgA negative (VN) and 100 EBV VCA-IgA positive healthy donors (VP). Plasma EBV VCA-IgA was determined by immunoenzymatic techniques. RESULTS: Thirty-four of the 174 cytokines varied significantly between the VP and NPC group. Plasma MIF and CCL3 were significantly elevated in NPC patients compared with VN and VP. Combination of MIF and CCL3 could be used for the differential diagnosis of NPC from VN cohort (area under the curve [AUC], 0.913; sensitivity, 90.00%; specificity, 80.30%), and combination of MIF, CCL3, and VCA-IgA could be used for the differential diagnosis of NPC from VP cohort (AUC, 0.920; sensitivity, 90.00%; specificity, 84.00%), from (VN+VP) cohort (AUC, 0.961; sensitivity, 90.00%; specificity, 92.00%). Overexpressions of MIF and CCL3 were observed in NPC plasma, NPC cell lines and NPC tissues. CONCLUSION: Plasma MIF, CCL3, and VCA-IgA combination significantly improves the diagnostic specificity of NPC in high-risk individuals.

Comparative Studies of Two Major Sets of Tibetan Medical Paintings: A Historical Perspective / 中国结合医学杂志

Tibetan medicine, one of the time-honored medical systems in the world, has increasingly been receiving attention the world over. Tibetan medical paintings (TMP, tib. Sman thang) has become one of the focal points in the studies of this medical system. To date, there are many atlases and publications on TMP, which are principally based on the two major sets of TMP series existing today in the world, the Lhasa set and the Buryat set. It has been found that the Buryat set is based on the Lhasa set, which was brought in late 19th to the first half of the 20th century from Tibet to Buryatia, Russia. A careful investigation on the basic structure of the two sets reveals that there are many differences between the two sets of paintings, including the total number of the paintings involved, of which some are missing in one set, the details of the captions of some of the paintings, the existence of the 80th painting and its supervisor, and the overall order of the entire set, etc. The details of the differences are elaborated and discussed, and the prospective of developing the research to arrive at a standard and perfect TMP set in the future is also analyzed and anticipated.

Success rates of in vitro fertilization versus intracytoplasmic sperm injection in men with serum anti-sperm antibodies: a consecutive cohort study / 亚洲男科学杂志(英文版)

Antisperm antibodies (ASAs) are assumed to be a possible causative factor for male infertility, with ASAs detected in 5%-15% of infertile men but in only 1%-2% of fertile ones. It remains unclear whether ASAs have an adverse effect on the outcome of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). This study investigated differences in the rates of fertilization, pregnancy, and live births associated with serum ASA-positive and ASA-negative men following IVF or ICSI. Five hundred and fifty-four consecutive infertile couples undergoing IVF (n = 399) or ICSI (n = 155) were included. The two-sample two-sided t-test and Chi-square or Fisher's exact test was used for statistical analysis. Lower rates of fertilization (41.7% vs 54.8%, P = 0.03), good embryos (18.9% vs 35.2%, P = 0.00), pregnancy (38.5% vs 59.4%, P = 0.00), and live births (25.8% vs 42.5%, P = 0.00) were observed in men of the IVF group with a positive serum ASA than in those with a negative ASA. ASA positivity/negativity correlated with pregnancy rates (P = 0.021, odds ratio [OR]: 0.630, 95% confidence interval [CI]: 0.425-0.932) and live birth rates (P = 0.010, OR: 1.409, 95% CI: 1.084-1.831) after controlling for the female serum follicle-stimulating hormone level and the couple's ages at IVF. Women coupled with ASA-positive men had lower live birth rates with IVF than with ICSI (25.8% and 47.4%, respectively; P = 0.07). Women coupled with ASA-positive men had lower rates of pregnancy and live births following IVF than those coupled with ASA-negative men but had a similar outcome with ICSI.
