Chronic liver diseases with common causes including viral infections， alcohol abuse， and autoimmune diseases. Alkaloids， as a class of plant-derived compounds， have shown significant potential in regulating chronic liver diseases. Recent studies have shown that alkaloids are able to exert a therapeutic effect on chronic liver diseases through multiple pathways. These compounds have a regulatory effect on key pathological processes such as liver fibrosis， inflammatory response， oxidative stress， and cell apoptosis， and they also regulate the metabolic homeostasis of hepatocytes by modulating multiple signaling pathways， thereby playing a role in regulating chronic liver diseases. This article reviews the role and mechanism of alkaloids in the treatment of chronic liver diseases， in order to provide new ideas and directions for the treatment of chronic liver diseases.

Objective:To investigate the efficacy, safety and recurrence rate of oral atenolol in the treatment of infantile hemangioma, so as to provide evidence-based medicine basis and reference for clinic.Methods:Search on the following public databases from January 1, 2008 to June 13, 2022: Web of Science, PubMed, Cochrane Library, Embase, U. S. National Library of Medicine Clinical Trials Registry Platform; China National Knowledge Infrastructure(CNKI), Chinese Biomedical Literature Service System(SinoMed), Chinese Science and Technology Journal Database and Wanfang Data. According to inclusion and exclusion criteria, studies on oral atenolol for the treatment of infantile hemangioma were selected. The outcome indicators were efficiency (complete response rate), incidence of adverse effects and recurrence rate. The single-arm meta-analysis was performed using R software version 4.1.2. Egger’s test was employed and funnel plots were drawn to assess publication bias in the literature.Results:A total of 14 studies were included, comprising 5 randomized controlled trials, 5 single-arm studies, 3 non-randomized controlled trials, and 1 case-control study. The oral administration of atenolol for the treatment of infantile hemangiomas resulted in an efficacy rate (complete remission rate) of 62% (95% CI 52%~71%). The incidence rate of adverse reactions related to the digestive system was 18% (95% CI 7%~30%), while that related to β2 receptor blockade was 4% (95% CI 2%~6%), central nervous system-related adverse reactions occurred at a rate of 10% (95% CI 5%~16%), the recurrence rate was 5% (95% CI 2%~9%). Egger’s test indicated that there was no significant publication bias in the efficacy rate, central nervous system-related adverse reaction rate, and gastrointestinal-related adverse reaction rate of oral atenolol treatment for infantile hemangiomas ( P>0.05). The sensitivity analysis for the efficacy rate, adverse reaction rate, and recurrence rate of oral atenolol treatment for infantile hemangiomas suggested that the result were stable and reliable. Conclusion:Oral administration of atenolol for the treatment of infantile hemangiomas demonstrates significant efficacy, fewer adverse reactions, and a low recurrence rate, making it a promising candidate as a reasonable alternative to oral propranolol for treating infantile hemangiomas.

Acute pancreatitis (AP) is a severe disease with an increasing incidence rate in clinical practice. Although most patients have mild pancreatitis, the fatality rate of severe pancreatitis remains at a relatively high level, and therefore, early-stage, simple, and accurate clinical scoring systems are urgently needed to determine the severity of AP, so as to facilitate effective disease management and symptomatic treatment and reduce the fatality rate of patients. At present, a large number of studies have demonstrated that the scoring systems such as Ranson score, APACHE Ⅱ score, BISAP score, CTSI score, and some serological markers have been used to evaluate the severity and prognosis of AP, but all of them have certain limitations. This article reviews the research advances in the existing scoring systems, single serological markers, and related modified scoring systems in recent years. Through a literature review, it is concluded that there is no a single scoring system or a single indicator that can cover the whole process of AP diagnosis and treatment and accurately judge the severity of AP, and therefore, it is necessary to develop a new scoring system or combine various indicators for comprehensive evaluation.

Objective: To investigate the risk factors of prolonged postoperative length of stay (LOS) in patients with gastric cancer. Methods: A retrospective study was performed on 2033 patients who underwent curative surgery in Department of Pancreatic-gastric, Cancer Hospital, Chinese Academy of Medical Sciences. Eightieth percentile of postoperative hospital stay for all patients was taken as the cutoff, the patients were divided into the normal group (1 532 patients) and the extended group (501 patients). Logistic regression model was used to determine the risk factors related to prolonged postoperative LOS in gastric cancer. Results: A total of 417 cases with postoperative complications were recruited in extended group. The five highest complications accounting for prolonged LOS were: abdominal infection in 69 cases (13.77%), pleural effusion in 60 cases (11.98%), anastomotic leakage in 43 cases (8.58%), poor wound healing in 34 cases (6.79%), and bleeding in 25 cases (4.99%). Logistic regression analysis showed that age (OR=1.348, P=0.013), surgical procedure (OR=2.712, P<0.001), extent of resection (OR=2.035, P<0.001), degree of incision healing(OR=4.867, P<0.001), and perioperative blood transfusion (OR=1.711, P<0.001) were independent risk factors for prolonged postoperative LOS. Conclusions The most common complication associated with prolonged postoperative LOS for gastric cancer patients is abdominal infection. Age, surgical procedure, extent of resection, degree of incision healing, and perioperative blood transfusion are the independent risk factors for prolonged postoperative LOS.

We have previously reported that Cystatin C (CysC) is a pivotal mediator in the neuroprotection induced by hyperbaric oxygen (HBO) preconditioning; however, the underlying mechanism and how CysC changes after stroke are not clear. In the present study, we demonstrated that CysC expression was elevated as early as 3 h after reperfusion, and this was further enhanced by HBO preconditioning. Concurrently, LC3-II and Beclin-1, two positive-markers for autophagy induction, exhibited increases similar to CysC, while knockdown of CysC blocked these elevations. As a marker of autophagy inhibition, p62 was downregulated by HBO preconditioning and this was blocked by CysC knockdown. Besides, the beneficial effects of preserving lysosomal membrane integrity and enhancing autolysosome formation induced by HBO preconditioning were abolished in CysC rats. Furthermore, we demonstrated that exogenous CysC reduced the neurological deficits and infarct volume after brain ischemic injury, while 3-methyladenine partially reversed this neuroprotection. In the present study, we showed that CysC is biochemically and morphologically essential for promoting autophagic flux, and highlighted the translational potential of HBO preconditioning and CysC for stroke treatment.

Objective To evaluate the effect of TanshinonneⅡA preconditioning on nuclear factor kappa B ( NF-κB ) signaling pathway in N9 cells subjected to oxygen-glucose deprivation and restoration ( OGD∕R) . Methods N9 cells cultured in vitro were divided into 4 groups ( n=16 each) by using a ran-dom number table method: control group ( C group) , OGD∕R group, vehicle group ( V group) and Tanshi-none ⅡA preconditioning group ( TP group) . N9 cells were subjected to O2-glucose deprivation for 4 h fol-lowed by restoration of O2-glucose supply for 24 h to establish the OGD∕R model. Group C receive no treat-ment. In group TP, N9 cells were cultured in medium containing Tanshinone ⅡA ( final concentration 5 mg∕L) for 24 h before the model was established. Dimethyl sulfoxide was added to the culture medium in group V. At the 24 h of reoxygenation, the level of lactate dehydrogenase ( LDH) and nitric oxide ( NO) in culture medium was detected by spectrophotometry, cell apoptosis was assessed by using TUNEL, and the expression of NF-κB in nucleus was detected by Western blot. The apoptosis rate was calculated. Results Compared with group C, the levels of LDH, IL-β, TNF-α and NO in culture medium and apoptosis rate were significantly increased, and the expression of NF-κB in nucleus was up-regulated in OGD∕R, V and TP groups ( P<0. 05) . Compared with group OGD∕R, the levels of LDH, IL-β, TNF-αand NO in culture me-dium and apoptosis rate were significantly decreased, and the expression of NF-κB in nucleus was down-reg-ulated in group TP ( P<0. 05) , and no significant change was found in the parameters mentioned above in group V ( P>0. 05 ) . Conclusion The mechanism by which Tanshinonne ⅡA preconditioning reduces OGD∕R injury to N9 cells is related to inhibiting NF-κB signaling pathway.

Objective: To investigate the causes and impacts of unplanned reoperations (UO) in patients underwent colorectal cancer surgery, and its effect on the length of hospital stays and hospitalization fees of these patients. Methods: we retrospectively analyzed the data of colorectal tumor patients underwent resection and UO from January 2014 to November 2017 in Cancer Hospital, Chinese Academy of Medical Sciences (CAMS). Student t tests, ANOVA analysis and chi-square test were used to compare the paired data and data of multiple groups, respectively. Results: There were 5 923 cases who underwent colorectal cancer surgery from 2014 to 2017. Among them, 75 cases further accepted UO, the incidence rate of UO was 1.27%. Among the 75 patients of UO, 60 were male and 15 were female, 21 patients underwent colonic operation and 54 patients underwent rectal operation. The average length of hospital stays were 25.8 days and the average hospitalization fees were 110 647.04 yuan. The gender construction, surgical site, average length of hospital stays and hospitalization fees of UO were significantly different from those of operative colorectal tumor patients during this period (all P<0.01). There were 40 patients underwent anastomotic fistula, 11 patients underwent stoma complications and 10 patients underwent bowel obstruction, respectively, which accounts for the three most common causes of UO after colorectal cancer surgery, and the total incidence was 81.3%. The interval of reoperation and the first operation significantly impacted the average length of hospital stays of UO patients (P=0.003), while marginally affected the hospitalization fees (P=0.847). Conclusions UO are more possible to occur to the male patients who undergo rectal operation. The length of hospital stays and hospitalization fees of UO are significantly increased when compare to those of operative colorectal cancer patients. The time of reoperation significantly impacts the length of hospital stays but has little effect on the hospitalization fees of UO patients.

Stroke is a leading cause of death worldwide. Up to one thousand potential drugs or interventions have been developed to treat stroke, out of which ~160 have gone on to clinical trials. However, none of them has been successful. New insights into the molecular and cellular mechanisms of ischemia-induced injury are needed for discovering new therapeutic targets. Recently, Drosophila has been used to uncover new hypoxia-related genes. In this study, we describe an efficient and reliable assay with a sophisticated apparatus for studying the effects of oxygen deprivation on flies. Using this assay, wild-type flies were exposed to an anoxic environment for varying lengths of time, then the cumulative death rate and mobility recovery were systematically analyzed. We found that anoxia for over one hour caused lethality. The cumulative death rate on day 5 after anoxia was linearly and positively correlated with the duration of anoxia, and reached 50% when the duration was 2.5 h-3 h. We also found that the mobility recovery in normoxia was slow, as the climbing ability remained largely unchanged 4 h-6 h after 2.5-h of anoxia. We suggest that 2.5 h-3 h of anoxia and 4 h-6 h of recovery before mobility analysis are appropriate for future use of the anoxia assay.
