To review the clinical characteristics, short-term outcomes, and risk factors of patients with infective endocarditis(IE) who underwent surgical treatment at a single center, and to summarize treatment experience.

Objective To study the influence of ANGPTL8 in lipopolysaccharide(LPS)-induced hepatic lipid deposition.Methods Male wild-type(WT)and ANGPTL8 knockout mice at 6-8 weeks were used to induce sepsis models by intrabitoneal injection of LPS(10 mg/kg).qPCR and immunofluorescence were used to detected the mRNA and protein expression of ANGPTL8 in liver tissue and HepG2 cells respectively;The contents of alanine aminotransferase(ALT),aspartate aminotransferase(AST)in serum and the triglyceride(TG)and malondialdehyde(MDA)in liver homogenate were detected by kits;the histopathological changes of liver tissue were analyzed through HE staining.Lipids accumulation in liver were detected by oil red O staining.The apoptosis of liver was determinated by TUNEL staining.RNA-seq was used to analyzing the differentially expressed genes in the liver tissue of WT and ANGPTL8 KO mice,and the qPCR and Western Blot were used to verify the differential expressed genes.Results The expression of ANGPTL8 in the liver was significantly upregulated at 48 hours after LPS stimulation.Compared with WT mice,the hepatic lipid deposition,steatosis,and apoptosis were significantly alleviated in liver of ANGPTL8 KO mice,the ALT and AST levels in serum and the TG and MDA content in liver homogenate of ANGPTL8 KO mice were also reduced significantly.The expression of caveolin-1(CAV1)in liver of ANGPTL8 KO mice was significantly higher than that of WT mice.Conclusions LPS promoted the expression and secretion of ANGPTL8 in liver tissue,and ANGPTL8 increased hepatic lipid deposition and peroxidation by inhibiting the expression of CAV1.

Critical care medicine-related treatment is an interdisciplinary and multi-professional process,often leading to secondary or concomitant mental disorders in clinical practice.Currently,there is no consensus on the pharmacological treatment of related mental illnesses in China.The Chinese Society of Psychosomatic Medicine collaborated with the Critical Care Medicine expert group to form a consensus writing expert group.After a systematic review of relevant literature,summarizing published domestic and foreign literature,and extensive discussions,the consensus was developed.The consensus elaborates on the principles and processes of the standardized use of psychotropic drugs in critical care medicine,as well as the clinical indications,precautions,and specific drug selection of various psychiatric medications,providing feasible suggestions and guidance for the clinical application of psychiatric medications in the intensive care unit.

Background and aims:Antiviral therapy is essential for hepatitis B virus-related acute-on-chronic liver failure(HBV-ACLF).No data are available on the long-term prognosis or safety of tenofovir alafenamide(TAF),tenofovir disoproxil fumarate(TDF),or entecavir(ETV)in treating HBV-ACLF globally.This study was conducted to investigate the long-term efficacy and safety of the three nucleos(t)ide analogs in the treatment of HBV-ACLF.Methods:In this prospective,real-world cohort study,patients with HBV-ACLF were assigned to the TAF,TDF,and ETV groups.A total of 199 patients completed the 144-week follow-up.After propensity score matching(PSM),44 patients remained in each group for further analysis of survival status,incidence of hepatocellular carcinoma(HCC),virological response,and liver and renal function indicators.Results:In the original cohort,HCC developed in one patient in each group.No serious drug-related adverse events were observed.In the PSM cohort,the 144-week survival rates were 56.82％,75.00％,and 59.09％in the TAF,TDF,and ETV groups,respectively(P=0.118).When stratified into noncirrhosis and cirrhosis subgroups at baseline,the survival rate of the ETV group was slightly lower than that of the TAF and TDF group in noncirrhosis patients(P=0.338),and the survival rate of the TAF group was slightly lower than that of the TDF and ETV group in cirrhosis patients(P=0.052),but the differences were not statistically significant.The long-term overall survival rates in the TAF,TDF,and ETV groups were comparable.After 144 weeks,no significant difference in the virological response rate or liver or renal function indicators was found among the three groups,except for the level of aspartate amino-transferase,which was significantly higher in the TDF group than in the ETV group at week 144(P=0.001).Conclusions:There were no significant differences in the survival rate,incidence of HCC,efficacy or safety associated with the use of these three nucleos(t)ide analogs in treating HBV-ACLF.Trial registration:ClinicalTrials.gov NCT03920618.

Background::Pre-operative assessment with high-resolution magnetic resonance imaging (MRI) is useful for assessing the risk of local recurrence (LR) and survival in rectal cancer. However, few studies have explored the clinical importance of the morphology of the anterior mesorectum, especially in patients with anterior cancer. Hence, the study aimed to investigate the impact of the morphology of the anterior mesorectum on LR in patients with primary rectal cancer.Methods::A retrospective study was performed on 176 patients who underwent neoadjuvant treatment and curative-intent surgery. Patients were divided into two groups according to the morphology of the anterior mesorectum on sagittal MRI: (1) linear type: the anterior mesorectum was thin and linear; and (2) triangular type: the anterior mesorectum was thick and had a unique triangular shape. Clinicopathological and LR data were compared between patients with linear type anterior mesorectal morphology and patients with triangular type anterior mesorectal morphology.Results::Morphometric analysis showed that 90 (51.1%) patients had linear type anterior mesorectal morphology, while 86 (48.9%) had triangular type anterior mesorectal morphology. Compared to triangular type anterior mesorectal morphology, linear type anterior mesorectal morphology was more common in females and was associated with a higher risk of circumferential resection margin involvement measured by MRI (35.6% [32/90] vs. 16.3% [14/86], P = 0.004) and a higher 5-year LR rate (12.2% vs. 3.5%, P = 0.030). In addition, the combination of linear type anterior mesorectal morphology and anterior tumors was confirmed as an independent risk factor for LR (odds ratio = 4.283, P = 0.014). Conclusions::The classification established in this study was a simple way to describe morphological characteristics of the anterior mesorectum. The combination of linear type anterior mesorectal morphology and anterior tumors was an independent risk factor for LR and may act as a tool to assist with LR risk stratification and treatment selection.

Hepatitis B virus (HBV) infection is closely associated with the adverse events such as liver cirrhosis, liver cancer, and liver failure and remains a serious threat to human health. Pegylated interferon is an indispensable drug for the treatment of chronic hepatitis B (CHB), and interferon-stimulated genes are associated with a variety of viruses, but few studies have mentioned their association with hepatitis B and their predictive effect after the treatment of hepatitis B with interferon. This article introduces the predictive factors for interferon treatment of CHB and summarizes the association of interferon-stimulated genes with hepatitis B and their predictive effect, so as to provide a reference for clinical work and basic research.

BACKGROUND: Postoperative chylous ascites is an infrequent condition after colorectal surgery and is easily treatable. However, its effect on the long-term oncological prognosis is not well established. This study aimed to investigate the short-term and long-term impact of chylous ascites treated with neoadjuvant therapy followed by rectal cancer surgery and to evaluate the incidence of chylous ascites after different surgical approaches. METHODS: A total of 898 locally advanced rectal cancer patients treated with neoadjuvant chemoradiotherapy followed by surgery between January 2010 and December 2018 were included. The clinicopathological data and outcomes of the patients with chylous ascites were compared with those of the patients without chylous ascites. The primary endpoint was recurrence-free survival (RFS). To balance baseline confounders between groups, propensity score matching (PSM) was performed for each patient with a logistic regression model. RESULTS: Chylous ascites was detected in 3.8% (34/898) of the patients. The incidence of chylous ascites was highest after robotic surgery (6.9%, 6/86), followed by laparoscopic surgery (4.2%, 26/618) and open surgery (1.0%, 2/192, P = 0.021). The patients with chylous ascites had a significantly higher number of lymph nodes harvested (15.6 vs. 12.8, P = 0.009) and a 3-day longer postoperative hospital stay (P = 0.017). The 5-year RFS rate was 64.5% in the chylous ascites group, which was significantly lower than the rate in the no chylous ascites group (79.9%; P = 0.007). The results remained unchanged after PSM was performed. The chylous ascites group showed a nonsignificant trend towards a higher peritoneal metastasis risk (5.9% vs. 1.6%, P = 0.120). Univariate analysis and multivariate analysis confirmed chylous ascites (hazard ratio= 3.038, P < 0.001) as an independent negative prognostic factor for RFS. CONCLUSIONS Considering the higher incidence of chylous ascites after laparoscopic and robotic surgery and its adverse prognosis, we recommend sufficient coagulation of the lymphatic tissue near the vessel origins, especially during minimally invasive surgery.

OBJECTIVE: To investigate the efficacy and safety of the bladder training in male patients before urinary catheter removal after mid-low rectal cancer surgery. METHODS: This was a prospective, open, randomized controlled study. INCLUSION CRITERIA: male patients; pathologically diagnosed as mid-low rectal adenocarcinoma; distance from tumor lower edge to anal margin ≤10 cm; standard radical surgery for rectal cancer, including intestinal resection and regional lymph node dissection. EXCLUSION CRITERIA: previous history of benign prostatic hyperplasia or history of prostate surgery; bladder dysfunction such as dysuria and urinary retention before surgery; local resection of rectal tumor or extended resection. According to the above criteria, 92 patients who underwent colorectal surgery at the Union Hospital of Fujian Medical University from June to December 2016 were prospectively included. The patients were randomly divided into bladder training group (n=43) and bladder non-training group (n=49) according to the random number table method. The study was approved by the Ethics Committee of the Union Hospital of Fujian Medical University (ethical approval number: 2016KY005) and registered with the China Clinical Trial Registration Center (ChiCTR) (registration No.ChiCTR-IOR-16007995). The implementation of patient's treatment measures, the data collection and analysis were based on the three-blind principle, using envelopes for distribution concealment. In the bladder training group, bladder training was routinely performed from the first day after operation to catheter removal, and in bladder non-training group the catheter was kept open till its removal. The catheter was removed in the early morning at the 5th day after surgery, and the spontaneous urine output was recorded and the residual urine volume of the bladder was measured after the first urination. The international prostate symptom score (IPSS) was applied to evaluate the patient's urinary function before and after surgery. RESULTS: The age of whole group was (58.6±10.9) years old, the body mass index was (22.4±2.7) kg/m , and the distance from tumor lower edge to anal margin was (6.5±1.9) cm. The baseline data, such as age, body mass index, distance from tumor lower edge to anal margin, preoperative IPSS score, preoperative bladder residual urine volume, neoadjuvant radiotherapy and chemotherapy, preventive ileostomy and surgical procedure were not significantly different between two groups (all P>0.05). There was no significant difference in IPSS scores evaluated at the second day (3.6±4.0 vs. 3.5±3.4, t=0.128, P=0.899) and one month (3.7±2.9 vs. 3.0±3.1, t=1.113, P=0.269) after catheter removal between the bladder training group and bladder non-training group. No significant difference in the postoperative residual urine volume of bladder (media 44 ml vs. 24 ml, Z=-1.466, P=0.143), the first spontaneous urination volume (median 200 ml vs. 150 ml, Z=-1.228, P=0.219) after catheter removal, and postoperative hospital stay [(8.2±4.5) days vs. (9.1±5.5) days, t=-0.805, P=0.423] was found. Urinary infection rate was 20.9%(9/43) in the training group, which was even higher than 8.2%(4/49) in the non-training group, but the difference was not significant(χ²=3.077, P=0.079). No patient needed re-catheterization in either group. CONCLUSIONS The routine bladder training after mid-low rectal cancer surgery does not improve the urinary function, and can not reduce the residual urine volume of bladder after catheter removal. This routine clinical practice is not helpful for the bladder function recovery after rectal cancer surgery.

Objective:To develop an HPLC method for the determination of nintedanib in rabbit plasma and study the pharmacoki-netics of nintedanib in rabbits. Methods:The separation was performed on an Agilent ZORBAX SB-C18 column. A mixture of acetoni-trile-0. 1% trifluoroacetic acid-water (35∶ 20∶ 45) was used as the mobile phase at a flow rate of 1. 0 ml·min-1. The detection wavelength was set at 286 nm. Carbamazepine was used as the internal standard and nintedanib was extracted by ethyl acetate from plasma under basic condition. Totally 6 rabbits were given 20 mg·kg-1 nintedanib with intravenous administration. The blood samples were collected from the auricular vein at different time points after the administration. The concentration of nintedanib in plasma was detected by the HPLC method. The pharmacokinetics parameters were analyzed by DAS program. Results: An excellent linear rela-tionship was obtained within the range of 0. 05-10. 00 μg·ml-1(r=0. 999 8). The intra-day RSD was 5. 55%, 4. 53% and 2. 74%and inter-day RSD was 6. 15%, 5. 45% and 3. 15%, respectively for the three concentrations(0. 10, 2. 50 and 7. 50μg·ml-1), and the relative recovery was (98. 50 ± 5. 47)%, (100. 25 ± 4. 54)% and (99. 94 ± 2. 74)%, respectively. The main pharmacokinetics parameters of nintedanib were as follows: Cmaxwas (3.01 ±0.35) μg·ml-1, t1/2 was (4.38 ±1.53) h and AUC0-t was (11.67 ± 1. 71) μg·h·ml-1 . Conclusion:The method is simple, rapid and accurate, and can be used to determine the nintedanib concentra-tion in rabbit plasma and study its pharmacokinetics. Nintedanib is fitted the first-order elimination kinetics in rabbits.

Objective:To compare the expression and biological activity of glucosyl transferases (GTFs)of Streptococcus mutans (S.mutans)under normal outside environment between high temperature requirment serine proteinase A(HtrA)-deficient strains and high virulent strains isolated from children with high cario-susceptibility.Methods:The HtrA-deficient strains and high virulent strains of S.mutans were obtained by preliminary study.The strains were reanimated and incubated in BHI medium to exponential phase at tenth hour.The expression of gtfB,gtfC and gtfD were detected by real-time RT-PCR.The biological activity of the GTFs were detected by entong sulfuric acid method and Western Blot.Results:The expression of gtfs and GTFs in the HtrA-deficient strains was higher than those of high virulent strains,but the biological activity of the GTFs was lower.Conclusion:The HtrA gene plays an important regulatory role in the process of the GTFs expression of S.mutans isolated from children with high cario-susceptibility.
