In recent years, the development of host-acting antibacterial compounds has gradually become a hotspot in the field of anti-infection. Through research on the interaction mechanism between hosts and pathogenic bacteria, it has been found that the immune system is one of the key targets of host-acting antibacterial compounds. There is a communication system called the quorum sensing system in microorganisms, which mainly adjusts the structure of multi-microbial community and coordinates the group behavior. When the quorum sensing molecules secreted by microorganisms reach a threshold concentration, the quorum sensing system is activated and the overall gene expression of the microorganism is changed. In addition to regulating the density of microorganisms, quorum sensing molecules can also act as a link between pathogenic microorganisms and hosts, entering the host immune system and playing a role in affecting the morphological structure of immune cells, secreting cytokines, and inducing apoptosis, leading to host immune injury and causing host immune dysfunction.The key mechanism of 3-oxo-C12-HSL and other acyl-homoserine lactone (AHL) molecules in the innate immune system has been extensively studied. The lipid solubility allows AHLs to pass through the plasma membrane of host immune cells easily and induce dissolution of lipid domains. Then, it acts through signaling pathways such as p38MAPK and JAK-STAT, further influencing the immune cell’s defense response to bacteria and potentially leading to cell apoptosis. Additionally, the human lactonase paraoxonase 2, which can degrade3-oxo-C12-HSL, has been found in macrophage. It acts as an immune regulator that promotes macrophage phagocytosis of pathogens and is hypothesized to have the ability to reduce bacterial resistance. The mechanism of quorum sensing molecules in the adaptive immune system is less studied, the current results suggest that 3-oxo-C12-HSL is closely related to the mitochondrial pathway in host immune cells. For example, 3-oxo-C12-HSL induces apoptosis of Jurkat cells by inhibiting the expression of three mitochondrial electron transport chain proteins; it can also trigger mitochondrial dysfunction and induce mast cell apoptosis through Ca²⁺ signaling.Among the quorum sensing molecules, the AHLs have the greatest impact on plant immune system. The different effects on plant resistance depends on the chain lengths of acyl groups in bacterial-produced AHLs. Short-chain AHLs (C4-HSL and C8-HSL) induce plant resistance to pathogenic bacteria mainly through the auxin pathway and jasmonic acid pathway. Long-chain AHL (3-oxo-C14-HSL) is commonly used in hosts against fungal pathogens by inducing stomata defense responses, and the reaction process is related to salicylic acid. Diffusible signal factor molecules also interfere with the stomatal immunity caused by pathogens. It may act through the formin nanoclustering-mediated actin assembly and MPK3 pathway to inhibit the innate immunity of Arabidopsis. In summary, AHLs induced different plant pathways and affects the plant-bacteria interactions to trigger plant immunity. As a quorum sensing molecule of fungi, farnesol has similar effects on host immunity as AHLs, such as stimulating cytokine secretion and activating an inflammatory response. It also plays a unique role on dendritic cell differentiation and maturation. In addition, studies have found that farnesol has a protective effect on autoimmune encephalomyelitis, which may be related to its effect on the composition of intestinal microorganisms of the host.Therefore, targeting the host immune system and quorum sensing molecules to develop antibacterial compounds can effectively inhibit the invasion of pathogens and subserve the host to resist the influence of pathogenic bacteria. This article will review the mechanism of host immune responses triggered by important quorum sensing molecules, aiming to explore the targets of host-acting antibacterial compounds and provide new directions for the prevention or treatment of causative infectious sources and the development of related drugs.

GNPS-based mass spectrum-molecular networks is an effective strategy for rapidly identifying known natural products and discovering novel structures. The chemical diversity of azaphilones from the fermentation extracts of Talaromyces sp. HK1-18 was studied by molecular network technique. Three linear tricyclic azaphilones, sequoiamonacins A-C (2a, 2b, 1), were isolated by silica gel column chromatography and high performance liquid chromatography from the extracts of the fungal strain of HK1-18, and their structures were identified by nuclear magnetic resonance and high-resolution mass spectrometry. Guided by the mass spectra of sequoiamonacins A-C (2a, 2b, 1), the cluster of sequoiamonacinoid analogues was discovered from the full molecular networking of HK1-18. By analyzing the MS/MS fragments of each parent ion in this cluster, 7 azaphilones (3-9) included 6 new ones (4-9) were predicted successfully. Then the MS/MS cracking regularity of this type of azaphilones was revealed. Compound 1 showed anti-inflammatory activity, which can inhibit the production of interleukin-1α (IL-1α) in lipopolysaccharide (LPS)-induced mouse macrophage RAW264.7, with an inhibitory rate of 29% at the concentration of 12.5 μg·mL^-1.

Objective To explore the characteristics of blood pressure in the elderly patients with hypertensive cerebral small vessel disease(CSVD)and their correlation with traditional Chinese medicine(TCM)syndrome types.Methods A retrospective analysis was conducted in 189 elderly patients with essential hypertension.With reference to the presence or absence of CSVD,the patients were divided into CSVD group(87 cases)and non-CSVD group(102 cases).The blood pressure related parameters and clinical data obtained by four diagnostic methods of TCM in the two groups were collected,and then the characteristics of blood pressure and their correlation with TCM syndromes were analyzed with statistical methods.Results(1)CSVD group had higher values than non-CSVD group in the ambulatory blood pressure parameters of 24-hour systolic blood pressure(24hSBP),24-hour diastolic blood pressure(24hDBP),daytime systolic blood pressure(DSBP),daytime diastolic blood pressure(DDBP),nighttime systolic blood pressure(NSBP),nighttime diastolic blood pressure(NDBP),24-hour pulse pressure(24hPP),daytime pulse pressure(DPP),nighttime pulse pressure(NPP),maximum SBP,morning SBP,daytime SBP load and nighttime SBP load(P＜0.01).(2)The analysis of blood pressure variability showed that the mean value of nighttime SBP standard deviation(NSSD)in CSVD group was higher than that in the non-CSVD group(P＜0.01).(3)The analysis of circadian rhythm of blood pressure showed that there was significant difference in the comparison of circadian rhythm of ambulatory blood pressure between the two groups(P＜0.05):non-CSVD group was predominated by non-dipper type blood pressure(50 cases,49.02%)and dipper type blood pressure(31 cases,30.39%),and CSVD group was predominated by non-dipper type blood pressure(38 cases,43.68%)and super-dipper type blood pressure(31 cases,35.63%).(4)Logistic regression analysis showed that 24hSBP(OR=1.296,95%CI:1.112-1.511),maximum SBP(OR=1.074,95%CI:1.006-1.146),morning SBP(OR=1.064,95%CI:1.013-1.118),abnormal circadian rhythm of blood pressure(OR=3.736,95%CI:1.663-8.390)were the influence factors of CSVD(P＜0.05 or P＜0.01).(5)The analysis of the distribution of TCM syndrome types showed that non-CSVD group was dominated by accumulation of excess phlegm-damp syndrome(58.82%)and yin deficiency and yang hyperactivity syndrome(21.57%),and CSVD group was dominated by yin deficiency and yang hyperactivity syndrome(51.72%)and accumulation of excess phlegm-damp syndrome(21.84%).(6)The analysis of blood pressure in patients with various syndrome types showed that the DPP of patients with accumulation of excess phlegm-damp syndrome in the CSVD group was significantly higher than that in the non-CSVD group(P＜0.01),and the 24hDBP and NDBP of patients with yin deficiency and yang hyperactivity syndrome in the CSVD group were significantly higher than those in the non-CSVD group(P＜0.01).Conclusion It is indicated that 24hSBP,maximum SBP,elevated morning SBP,and abnormal blood pressure circadian rhythms may be the important risk factors for the hypertensive CSVD in the elderly.Elderly hypertensive patients with accumulation of excess phlegm-damp syndrome should pay more attention to the mean daytime pulse pressure,and elderly hypertensive patients with yin deficiency and yang hyperactivity syndrome should pay more attention to monitoring DBP.The dynamic observation and early control of the blood pressure is helpful for the prevention and treatment of CSVD in the elderly patients with hypertension.

Lipids,including fats(triglycerides)and lipoids(phospholipids and sterols),not only serve as an energy source for the body but also play a pivotal role throughout the reproductive process,particularly in the establishment and maintenance of early pregnancy.This encompasses the regulate of early embryonic development and uterine tolerance,and the facilitation of embryo implantation.Given the diversity of lipids,this review focuses on extensively studied lipid mediators such as polyunsaturated fatty acids,endocannabinoids,prostaglandins,lysophosphatidic acid,sphingolipids and steroid hormones.It systematically elaborates on the regulatory effects of fatty acid,phospholipid,and cholesterol metabolism on the formation of endometrial receptivity and embryo implantation,as well as the potential underlying mechanisms.The review aims to provide new insights and feasible intervention approaches for predicting and improving the outcomes of natural pregnancy and/or assisted reproductive technology.

The plateau zokor (Myospalax baileyi) and plateau pika (Ochotona curzoniae) are native species unique to the Qinghai-Tibetan Plateau with successful adaptation to the hypoxic environment. In this study, the number of red blood cells, hemoglobin concentration, mean hematocrit and mean volume of red blood cells were measured in plateau zokors and plateau pikas at different altitudes. Hemoglobin subtypes of two plateau animals were identified by mass spectrometry sequencing. The forward selection sites in two animals' hemoglobin subunits were analyzed by PAML4.8 program. Homologous modeling was used to analyze the effect of forward selection sites on the affinity of hemoglobin to oxygen. The adapting strategies of plateau zokors and plateau pikas to hypoxia at different altitudes were analyzed through comparing blood parameters between the two species. The results indicated that, with increasing altitudes, plateau zokors responded to hypoxia by increasing red blood cell count and decreasing red blood cell volume, while plateau pikas took the opposite strategies to plateau zokors. In erythrocytes of plateau pikas, both adult α₂β₂ and fetal α₂ε₂ hemoglobins were identified, while erythrocytes of plateau zokors only had adult α₂β₂ hemoglobin, however the affinities and the allosteric effects of the hemoglobin of plateau zokors were significantly higher than those of plateau pikas. Mechanistically, in the α and β subunits of hemoglobin of plateau zokors and pikas, the numbers and the sites of the positively selected amino acids as well as the side chain groups polarities and orientations of the amino acids differed significantly, which may result in the difference of the affinities to oxygen of hemoglobin between plateau zokors and pikas. In conclusion, the adaptive mechanisms to respond to hypoxia in blood properties of plateau zokors and plateau pikas are species-specific.

OBJECTIVE: To observe the clinical efficacy of targeted sealing with high viscosity bone cement and secondary injection of low viscosity bone cement in the treatment of OVCFs patients with the fracture lines involved vertebral body margin. METHODS: The elderly patients who underwent vertebroplasty for osteoporotic vertebral compression fractures from January 2019 to September 2021 were selected as the screening objects. Through relevant standards and further CT examination, 56 patients with fracture lines involving the anterior wall or upper and lower endplates of the vertebral body were selected for the study. There were 21 males and 35 females, aged from 67 to 89 years old with an average of (76.58±9.68) years. All 56 patients underwent secondary injection of bone cement during operation. Only a small amount of high viscosity cement was targeted to seal the edge of the vertebral body for the first time, and low viscosity cement was injected to the vertebral bodies during second bolus with well-distributed. The operation time, bone cement volume and bone cement leakage were recorded, and the pain relief was evaluated by visual analogue scale (VAS). RESULTS: All patients were followed up for more than 3 months and the surgeries were successfully complete. The operation time was (50.41±10.30) min and the bone cement volume was (3.64±1.29) ml. The preoperative VAS was (7.21±2.41) points, which decreased significantly to (2.81±0.97) points 3 days after operation(P<0.05). Among the 56 patients, 2 cases(3.57%) had bone cement leakage, 1 case leaked to the paravertebral vein, and 1 case slightly bulged to the paravertebral through the crack when plugging the vertebral crack. Both patients had no obvious clinical symptoms. CONCLUSION In vertebroplasty surgery, targeted sealing of high viscosity bone cement and secondary injection of low viscosity bone cement can reduce intraoperative bone cement leakage and improve the safety of operation.

Objective: To analyze the incidence of early severe complications following bariatric and metabolic surgery and the experience of their diagnosis, treatment, and risk factors. Methods: In this retrospective observational study, the clinical data of 4255 patients who underwent bariatric and metabolic surgery between May 2010 and May 2022 in the Department of Bariatric and Metabolic Surgery of the First Affiliated Hospital of Nanjing Medical University were retrospectively collected. Among these patients, 1125 were male and 3130 were female. The mean age and body mass index (BMI) of the patients at the time of operation were 31.3±4.5 years and 36.5±6.4 kg/m², respectively. Regarding surgical type, 2397 patients underwent sleeve gastrectomy (SG), 489 underwent Roux-en-Y gastric bypass (RYGB), 1028 underwent sleeve gastrectomy plus jejunojejunal bypass (SG+JJB), and 341 underwent single anastomosis duodenal switch (SADS). The inclusion criteria were patients (1) with a Clavien-Dindo grade of ≥III; (2) who were undergoing SG, RYGB, SG-JJB, or SADS; and (3) who had complete clinical data. The exclusion criteria were patients (1) undergoing revisional surgery and (2) other operations during the bariatric and metabolic surgery. The Clavien-Dindo classification was used to analyze the incidence of early severe postoperative complications and their prognosis. Early severe postoperative complications were defined as Clavien-Dindo ≥ III complications within 30 days after surgery. Meanwhile, multivariate logistic regression model was used to identify risk factors of the complications. Results: Summary of early severe complications following bariatric and metabolic surgery: (1) of the 4255 patients, 22 (12 male and 10 female) exhibited early severe complications (0.52%). The mean age and BMI of these patients were 41.1±9.9 years and 36.9±8.2 kg/m², respectively. Preoperatively, 7 patients had hypertension, 10 had type 2 diabetes mellitus, 1 had respiratory failure, and 1 had heart failure. The severe complications included 9 patients (0.21%) with grade IIIa, 11 (0.26%) with grade IIIb, 1 (0.02%) with grade IVa, and 1 (0.02%) with grade V complications. The incidences of severe postoperative complications in the different surgical procedures were 0.17% for SG (4/2397), 0.61% for RYGB (3/489), 0.58% for SG+JJB (6/1028), and 2.64% for SADS (9/341). The common severe complications were leakage (0.28%, 12 patients), bleeding (0.14%, 6 patients), and obstruction (0.05%, 2 patients). (2) Management of complications: Grade IIIa complications (including eight patients with leakage and one with severe inflammation) were treated with antibiotics, nasogastric and nutritional tube placements, and CT-guided drainage. For grade IIIa complications, five patients with bleeding were treated with reoperation, and all the patients recovered; four patients with leakage were treated with reoperation, wherein three were converted to RYGB and one patient underwent resuturing of the leakage site; two patients with obstruction were treated with adhesiolysis. The patient with grade IVa complication (including respiratory failure complicated with acid aspiration) was treated in the ICU. For the grade V complication, bleeding in a patient with SG+JJB was treated with reoperation, which confirmed the bleeding of short gastric vessels. Unfortunately, the patient died. (3) Risk factor analysis of early severe complications: univariate analysis detected that sex, age, type 2 diabetes mellitus, operation time, and surgical type were associated with postoperative complications (P<0.05). However, multivariate analysis indicated that an age of ≥31.3 years (odds ratio [OR] = 5.423, 95% confidence interval [CI]: 1.004-29.278, P=0.049) and surgical type (SADS: OR = 19.758, 95%CI: 5.803-67.282, P<0.001; RYGB: OR = 9.752, 95%CI: 2.456-38.723, P=0.001; SG+JJB: OR = 5.706, 95%CI: 1.966- 16.559, P=0.001) were independent risk factors of early severe complications following bariatric and metabolic surgery. Conclusion: Bariatric and metabolic surgery is safe. Its common postoperative complications include leakage, bleeding, and obstruction, which require early detection, diagnosis, and treatment to improve treatment outcomes. Age and surgical type are independent risk factors of early severe complications following bariatric and metabolic surgery.

This study aims to investigate the effects and the underlying mechanism of Huangqi Shengmai Decoction(HQSMD) in the treatment of fatigue and myocardial injury in a joint rat model. Wistar rats were assigned into 4 groups: sham, model, diltiazem hydrochloride(positive control), and HQSMD. The joint model of fatigue and myocardial injury was established by 14-day exhausted swimming followed by high ligation of the left anterior descending coronary artery. The rats in the sham group underwent a sham operation without coronary artery ligation or swimming. Since the fourth day after the ligation, swimming was continued in the model group and the drug-treated groups for the following 4 weeks. Meanwhile, the rats in the positive control group and the HQSMD group were respectively administrated intragastrically with diltiazem hydrochloride(20 mg·kg~(-1)·d~(-1)) and HQSMD(0.95 g·kg~(-1)·d~(-1)) for 4 weeks, while the shams and the models were given the same volume of normal saline. The left ventricular ejection fraction(LVEF), left ventricular fractional shortening(LVFS), grip strength, and myocardial pathophysiological changes were measured to evaluate the anti-fatigue and cardioprotective effects of HQSMD. The protein levels of PTEN-induced putative kinase 1(PINK1) and parkin in the myocardium were measured by Western blot to preliminarily elucidate the mechanism of HQSMD in ameliorating myocardial injury by suppressing mitochondrial autophagy. Compared with the shams, the models showed weakened heart function(LVEF and LVFS, P<0.01), decreased grasping ability(P<0.05), elevated blood urea nitrogen(BUN) and aldosterone(ALD) levels(P<0.01), aggravated myocardial fibrosis and connective tissue hyperplasia(P<0.01), and up-regulated protein levels of PINK1(P<0.01) and parkin(P<0.05). Four-week treatment with HQSMD increased the LVEF and LVFS levels(P<0.01), enhanced the grip strength(P<0.01), reduced the serum levels of BUN(P<0.01) and ALD(P<0.05), alleviated the pathological injury and fibrosis in the myocardium(P<0.01), and down-regulated the protein levels of PINK1(P<0.01) and parkin(P<0.05) in heart tissue. The results demonstrate that HQSMD may alleviate myocardial fibrosis and protect myocardium by suppressing the excessive mitochondrial auto-phagic activity and reducing the excessively elevated ALD level, thereby ameliorating fatigue and myocardial injury.

Objective: To examine the clinical effect of minimally invasive duodenum preserving pancreatic head resection(DPPHR) for benign and pre-malignant lesions of pancreatic head. Methods: The clinical data of patients with diagnosis of benign or pre-malignant pancreatic head tumor were retrospectively collected and analyzed,all of them underwent laparoscopic or robotic DPPHR between October 2015 and September 2021 at Division of Gastrointestinal and Pancreatic surgery,Zhejiang Provincial People's Hospital. Thirty-three patients were enrolled with 10 males and 23 females. The age(M(IQR)) was 54(32) years old(range: 11 to 77 years old) and the body mass index was 21.9(2.9)kg/m²(range: 18.1 to 30.1 kg/m²). The presenting symptoms included abdominal pain(n=12), Whipple triad(n=2), and asymptomatic(n=19). There were 7 patients with hypertension and 1 patient with diabetes mellitus. There were 19 patients who were diagnosed as American Society of Anesthesiologists class Ⅰ and 14 patients who were diagnosed as class Ⅱ. The student t test,U test, χ² test or Fisher exact test was used to compare continuous data or categorized data,respectively. All the perioperative data and metabolic morbidity were analyzed and experiences on minimally invasive DPPHR were concluded. Results: Fourteen patients underwent laparoscopic DPPHR,while the rest of 19 patients received robotic DPPHR. Indocyanine green fluorescence imaging was used in 19 patients to guide operation. Five patients were performed pancreatico-gastrostomy and the rest 28 patients underwent pancreaticojejunostomy. Pathological outcomes confirmed 9 solid pseudo-papillary neoplasms, 9 intraductal papillary mucinous neoplasms, 7 serous cystic neoplasms, 6 pancreatic neuroendocrine tumors, 1 mucous cystic neoplasm, 1 chronic pancreatitis. The operative time was (309.4±50.3) minutes(range:180 to 420 minutes),and the blood loss was (97.9±48.3)ml(range:20 to 200 ml). Eighteen patients suffered from postoperative complications,including 3 patients experienced severe complications(Clavien-Dindo Grade ≥Ⅲ). Pancreatic fistula occurred in 16 patients,including 8 patients with biochemical leak,7 patients with grade B pancreatic fistula and 1 patient with grade C pancreatic fistula. No one suffered from the duodenal necrosis and none perioperative death was occurred. The length of hospital stay was 14(7) days (range:6 to 87 days). The follow-up was 22.6(24.5)months(range:2 to 74 months). None suffered from recurrence or metastasis. During the follow-up,all the patients were free of refractory cholangitis. Moreover,in the term of endocrine dysfunction,no postoperative new onset of diabetes mellitus were observed in the long-term follow-up. However,in the view of exocrine insufficiency,pancreatic exocrine insufficiency and non-alcoholic fatty liver disease (NAFLD) was complicated in 2 and 1 patient,respectively,with the supplement of pancreatic enzyme,steatorrhea and weight loss relieved,but NAFLD was awaited to be seen. Conclusions: Minimally invasive DPPHR is feasible and safe for benign or pre-malignant lesions of pancreatic head. Moreover,it is oncological equivalent to pancreaticoduodenectomy with preservation of metabolic function without refractory cholangitis.

ObjectiveTo study the effect of Jinlida granules on visceral fat accumulation and its induced inflammatory response in prediabetic rats. MethodMale SD rats were randomly divided into normal group， model group， Jinlida low-dose group （1.5 g·kg^-1）， Jinlida high-dose group （3.0 g·kg^-1） and atorvastatin group （10 mg·kg^-1）. Prediabetic rat model was established using high-carbohydrate， high-fat diet combined with low-dose streptozotocin （STZ） by multiple small-dose intraperitoneal injections. After 8 weeks of modeling and drug intervention for 13 consecutive weeks， body weight， oral glucose tolerance test（OGTT）， fasting blood glucose （FBG）， fasting insulin （FINS）， insulin resistance index （HOMA-IR）， total cholesterol （TC）， low-density lipoprotein cholesterol （LDL-C） and high-density lipoprotein cholesterol （HDL-C） were measured in each group of rats. The content of visceral fat was quantified by micro-computed tomography （Micro-CT）. Hematoxylin-eosin staining （HE） was used to observe the pathological changes of fat cells. The levels of tumor necrosis factor-α （TNF-α） and interleukin- 6 （IL-6） in rat visceral fat and serum were determined by enzyme linked immunosorbent assay （ELISA）. The expression of macrophage marker CD68 in visceral fat was detected by immunofluorescence and Western blot. ResultCompared with normal group， model group had increased oral glucose tolerance， FBG， FINS， HOMA-IR， TC， LDL-C （P<0.01）， elevated body weight and visceral fat accumulation （P<0.05， P<0.01）， enhanced CD68 protein expression and TNF-α and IL-6 levels （P<0.01）， decreased HDL-C （P<0.01）， and abnormal hypertrophy of adipocytes. Compared with model group， Jinlida high- and low-dose groups lowered oral glucose tolerance， HOMA-IR， TC and LDL-C （P<0.05， P<0.01）， body weight and visceral fat accumulation （P<0.05）， and CD68 protein expression and TNF-α and IL-6 levels （P<0.05， P<0.01） and lessened hypertrophy of fat cells. ConclusionJinlida can improve the insulin resistance in prediabetic rats by reducing visceral fat accumulation and its induced inflammatory response， which provides a new pharmacological basis for clinical treatment of prediabetes by Jinlida granules.
