Management of liver transplantation perioperative period in acute-on-chronic liver failure / 中华肝脏病杂志

Acute-on-chronic liver failure (ACLF) is a potentially reversible entity that occurs in patients with chronic liver disease accompanied with or without cirrhosis and is characterized by extrahepatic organ failure and high short-term mortality. Currently, the most effective treatment method for patients with ACLF is liver transplantation; therefore, admission timing and contraindications must be emphasized. The function of vital organs such as the heart, brain, lungs, and kidneys should be actively supported and protected during the liver transplantation perioperative period in patients with ACLF. Focusing on the anesthesia management level during anesthesia selection, intraoperative monitoring, three-stage management, prevention and treatment of post-perfusion syndrome, monitoring and management of coagulation function, volume monitoring and management, and body temperature monitoring management for liver transplantation should strengthen anesthesia management. Additionally, standard postoperative intensive care treatment should be recommended, and grafts and other vital organ functions should be monitored throughout the perioperative period to promote early postoperative recovery in patients with ACLF.

Short-term outcomes and long-term quality of life after undergoing radical proximal gastrectomy with esophageal gastric tube anastomosis and total gastrectomy with Roux-en-Y anastomosis for Siewert type II and III adenocarcinoma of the esophagogastric junction: A propensity score matching analysis / 中华胃肠外科杂志

Objective: To evaluate the effects on short-term clinical outcomes and long-term quality of life of laparoscopic-assisted radical proximal gastrectomy with esophageal gastric tube anastomosis versus total gastrectomy with Roux-en-Y anastomosis for adenocarcinoma of the esophagogastric junction. Methods: This was a propensity score matching, retrospective, cohort study. Clinicopathological data of 184 patients with adenocarcinoma of the esophagogastric junction admitted to two medical centers in China from January 2016 to January 2021 were collected (147 in the First Affiliated Hospital of Xiamen University and 37 in the Affiliated Hospital of Qinghai University). All patients had undergone laparoscopic-assisted radical gastrectomy. They were divided into two groups based on the extent of tumor resection and technique used for digestive tract reconstruction. A proximal gastrectomy with reconstruction by esophageal gastric tube anastomosis group comprised 82 patients and a total gastrectomy with reconstruction by Roux-en-Y anastomosis group comprised 102 patients. These groups differed significantly in the following baseline characteristics: age, preoperative hemoglobin, preoperative albumin, tumor length, tumor differentiation, and tumor TNM stage (all P<0.05). To eliminate potential bias caused by unequal distribution between the two groups, 1∶1 matching was performed by the nearest neighbor matching method. The 13 matched variables comprised sex, age, height, body mass, body mass index, preoperative glucose, preoperative hemoglobin, preoperative total protein, preoperative albumin, neoadjuvant radiotherapy, tumor length, degree of differentiation, and pathological TNM stage. Postoperative complications, postoperative nutritional status, incidence of reflux esophagitis 1 year after surgery, and quality of life were compared between the two groups. Results: After propensity score matching, 60 patients each were enrolled in the proximal gastrectomy with esophageal gastric tube anastomosis and total gastrectomy with Roux-en-Y anastomosis groups. The baseline characteristics were comparable between these groups (all P>0.05). There were no significant differences between the two groups in operative time, intraoperative bleeding, time to semifluid diet, postoperative hospital days, tumor length, and total hospital costs (P>0.05). Patients in the proximal gastrectomy with esophageal gastric tube anastomosis group had earlier postoperative gastric tube and abdominal drainage tube removal time than those in the total gastrectomy with Roux-en-Y anastomosis group (t=-2.183, P=0.023 and t=-4.073, P<0.001, respectively). In contrast, significantly fewer lymph nodes were cleared and significantly fewer lymph nodes were positive in the proximal gastrectomy with esophageal gastric tube anastomosis group than in the total gastrectomy with Roux-en-Y anastomosis group (t=-5.754, P<0.001 and t=-2.575, P=0.031, respectively). The incidence of early postoperative complications was 43.3% (26/60) in the total gastrectomy with Roux-en-Y anastomosis group; this is not significantly higher than the 26.7% (16/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group (χ2=3.663，P=0.056). The incidences of pulmonary infection (31.7%, 19/60) and pleural effusion (30.0%, 18/60) were significantly higher in the total gastrectomy with Roux-en-Y anastomosis group than in the proximal gastrectomy with esophageal gastric tube anastomosis group (13.3%, 8/60 and 8.3%, 5/60, respectively); these differences are significant (χ2=8.711, P=0.003 and χ2=11.368, P=0.001, respectively). All early complications were successfully treated before discharge. The incidence of long-term postoperative complications was 20.0% (12/60) in the total gastrectomy with Roux-en-Y anastomosis group and 35.0% (21/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group; this difference is not significant (χ2=3.386，P=0.066). The incidence of reflux esophagitis was 23.3% (14/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group; this is significantly higher than the 1.7% (1/60) in the total gastrectomy with Roux-en-Y anastomosis group (χ2=12.876, P<0.001). Body mass index had decreased significantly in both groups 1 year after surgery compared with preoperatively; however, the difference between the two groups was not significant (P>0.05). The differences in hemoglobin and albumin concentrations between 1 year postoperatively and preoperatively were not significant (both P>0.05). Quality of life was assessed using the Visick grade. Visick grade I dominated in both groups. The percentage of patients with Visick II and III in the total gastrectomy with Roux-en-Y anastomosis group was 11.7% (7/60), which is significantly lower than the 33.3% (20/60) in the proximal gastrectomy with esophageal gastric tube anastomosis group (χ2=8.076, P=0.004). No patients in either group had a grade IV quality of life. Conclusions: Both proximal gastrectomy with esophageal gastric tube anastomosis and total gastrectomy with Roux-en-Y anastomosis laparoscopic-assisted radical surgery for adenocarcinoma of the esophagogastric junction are safe and feasible. However, both procedures have their own advantages and disadvantages in terms of postoperative complications. The incidence of reflux esophagitis is higher after proximal gastrectomy with esophageal gastric tube anastomosis, whereas the long-term quality of life is lower than that of patients after total gastrectomy with Roux-en-Y anastomosis.

Advances in genetic etiology research of congenital chest wall deformity / 中国胸心血管外科临床杂志

@#Congenital chest deformity is caused by abnormal development of spine or ribs, resulting in sternal depression or protrusion. Pectus carinatum and pectus excavatum are the most common diseases in clinic, which can either be accompanied by other syndromes or exist alone. The genetic factors of congenital thoracic deformity can be related to single gene mutation, polygene mutation and chromosome aberration. Common clinical congenital thoracic deformity with syndromes, such as Marfan syndrome and Noonan syndrome, often have relatively fixed and clear pathogenic genes. The genetic pathogenesis of non-syndromic and independent congenital thoracic malformations is usually diverse, and treatments for syndromic and non-syndromic congenital thoracic deformity are different. Therefore, it is necessary for us to differentiate syndromic and non-syndromic congenital thoracic deformities in basic research, clinical diagnosis and treatment.

Insulin resistance is associated with Sfrp5 in obstructive sleep apnea / Resistência à insulina está associada à Sfrp5 na apneia obstrutiva do sono

Abstract Introduction: Obstructive sleep apnea, a common disease, is usually complicated by insulin resistance and type 2 diabetes mellitus. Adipokine is considered to play an important role in the development of insulin resistance and type 2 diabetes mellitus in obstructive sleep apnea. Objective: To assess whether secreted frizzled-related protein 5, a new adipokine, is involved in untreated obstructive sleep apnea patients. Methods: Seventy-six subjects with obstructive sleep apnea and thirty-three control subjects without obstructive sleep apnea were recruited and matched in terms of body mass index and age. The fasting secreted frizzled-related protein 5 plasma concentration was tested using ELISA. In addition, the correlation between secreted frizzled-related protein 5 and the homeostasis model assessment of insulin resistance was obtained. Multiple linear regression analysis models with stepwise selection were performed to determine the independent associations between various factors and secreted frizzled-related protein 5. Results: Plasma secreted frizzled-related protein 5 levels were significantly lower in the obstructive sleep apnea group than in the control group (obstructive sleep apnea group: 28.44 ± 13.25 ng/L; control group: 34.16 ± 13.51 ng/L; p = 0.023). In addition, secreted frizzled-related protein 5 was negatively correlated with homeostasis model assessment of insulin resistance but positively correlated with the mean and lowest oxygen saturation with or without adjusting for age, gender, body mass index, neck circumference, waist circumference and waist-to-hip ratio. The multiple linear regression analysis showed there was an independent negative association between secreted frizzled-related protein 5 and homeostasis model assessment of insulin resistance. Conclusion: Secreted frizzled-related protein 5 was involved in obstructive sleep apnea and the decrease in secreted frizzled-related protein 5 was directly proportional to the severity of obstructive sleep apnea. There was an independent negative correlation between homeostasis model assessment of insulin resistance and secreted frizzled-related protein 5 in the obstructive sleep apnea group. Secreted frizzled-related protein 5 might be a therapeutic target for insulin resistance in obstructive sleep apnea.

Resumo Introdução: A apneia obstrutiva do sono, uma doença comum, é geralmente complicada com resistência à insulina e diabetes melito tipo 2. Acredita-se que a adipocina possa ter um papel importante no desenvolvimento de resistência à insulina e diabetes melito tipo 2 na apneia obstrutiva do sono. Objetivo: Avaliar se a proteína secretada relacionada ao receptor frizzled-5, uma nova adipocina, está envolvida em pacientes com apneia obstrutiva do sono não tratada. Método: Foram recrutados 76 indivíduos com apneia obstrutiva do sono e 33 indivíduos controle sem apneia obstrutiva do sono e pareados em relação a índice de massa corporal e idade. A concentração plasmática de proteína secretada relacionada ao receptor frizzled-5 foi testada em jejum com o teste Elisa. Além disso, obteve-se correlação entre a proteína secretada relacionada ao receptor frizzled-5 e o modelo de avaliação da homeostase de resistência à insulina. Modelos de análise de regressão linear múltipla com seleção stepwise foram feitos para determinar as associações independentes entre vários fatores e a proteína secretada relacionada ao receptor frizzled-5. Resultados: Os níveis plasmáticos de proteína secretada relacionada ao receptor frizzled-5 foram significativamente menores no grupo com apneia obstrutiva do sono do que no grupo controle (grupo com apneia obstrutiva do sono: 28,44 ± 13,25 ng/L; grupo controle: 34,16 ± 13,51 ng/L; p = 0,023). Além disso, a proteína secretada relacionada ao receptor frizzled-5 foi correlacionada negativamente com o modelo de avaliação da homeostase de resistência à insulina, mas se correlacionou positivamente com a média e a saturação mínima de oxigênio com ou sem ajuste para idade, gênero, índice de massa corporal, circunferência do pescoço, circunferência da cintura e relação cintura-quadril. A análise de regressão linear múltipla mostrou que houve uma associação negativa independente entre a proteína secretada relacionada ao receptor frizzled-5 e o modelo de avaliação da homeostase de resistência à insulina. Conclusões: A proteína secretada relacionada ao receptor frizzled-5 esteve envolvida na apneia obstrutiva do sono e sua diminuição foi diretamente proporcional à gravidade da apneia obstrutiva do sono. Houve uma correlação negativa independente entre o modelo de avaliação da homeostase de resistência à insulina e a proteína secretada relacionada ao receptor frizzled-5 no grupo da apneia obstrutiva do sono. A proteína secretada relacionada ao receptor frizzled-5 pode ser um alvo terapêutico para a resistência à insulina na apneia obstrutiva do sono.

Bioinformation analysis of chorismate synthase in Baphicacantus cusia and other 78 species of plants / 中国中药杂志

Chorismate synthase(CS, EC:4.2.3.5) catalyses 5-enolpyruvy-shikimate-3-phosphate to form chorismate, which is the essential enzyme for chorismate biosynthesis in organisms. The amino acid sequences of CS from 79 species of higher plants were reported in GenBank at present. 125 amino acid sequences of CS from Baphicacanthus cusia and other 78 species of plants were predicted and analyzed by using various bioinformatics software, including the composition of amino acid sequences, signal peptide, leader peptide, hydrophobic/hydrophilic, transmembrane structure, coiled-coil domain, protein secondary structure, tertiary structure and functional domains. The phylogenetic tree of CS protein family was constructed and divided into eight groups by phylogenetic analysis. The homology comparison indicated that B. cusia shared a high homology with several plants such as Sesamum indicum, Nicotiana tabacum, Solanum tuberosum and so on. The open reading frame(ORF) of all samples is about 1 300 bp, the molecular weight is about 50 kDa, the isoelectric point(pI) is 5.0-8.0 which illustrated that CS protein is slightly basic. The ORF of CS we cloned in B. cusia is 1 326 bp, the amino acid residues are 442, the molecular weight is 47 kDa and pI is 8.11. The CS in B.cusia showed obvious hydrophobicity area and hydrophilicity area, no signal peptide, and may exists transmembrane structure areas. The main secondary structures of CS protein are random coil and Alpha helix, also contain three main structural domains which are an active structural domain, a PLN02754 conserved domain and a FMN binding site. The acquired information in this study would provide certain scientific basis for further study on structure-activity relationship and structure modification of CS in plants in the future.

Objective To explore the feasibility and clinical outcome of laparoscopy-assisted gastrectomy with D2 dissection by comparing the efficacy of open surgery on radical gastrectomy with D2 dissection for gastric cancer patients. Methods The patients with gastric cancer from October 2008 to August 2013 were divided into two groups according to the different surgical methods. Among them, 175 patients underwent laparoscopic surgery (laparoscopy-assisted surgery group, Group L), and 163 patients underwent laparotomy surgery (open surgery group, Group O). The number of lymph nodes dissected, postoperative recovery, complications, mortality and survival rate of the two groups were compared and analyzed. Results There was no significant difference in the number of lymph nodes resect between the two groups [Group L and Group O: (26.3 ± 13.9) vs (26.8 ± 10.2), t = -0.40, P = 0.684]. Compared with open surgery, the laparoscopy-assisted surgery showed significantly less intraoperative blood loss and quicker recovery of gastrointestinal function. The postoperative hospitalization time of laparoscopic group was less than that of laparotomy group, the difference was statistically significant (P < 0.05). No significant difference was found in 3-year survival rate between the two groups (Group L vs Group O: 92.00％ vs 92.63％, P = 0.262). Conclusions Compared to open surgery, laparoscopic gastrectomy is safer and has quicker postoperative recovery. There is no statistical difference in the number of resect lymph nodes between lapamscopic and open gastrectomy.

Research progress of 5-hydroxymethylfurfural, a safety-related substance in traditional Chinese medicine injections / 中国中药杂志

Screening out the safety-related substances and establishing the corresponding standard has been a key research issue to improve the safety of traditional Chinese medicine injections(TCMIs). 5-HMF which widely exists in sugar-containing TCMIs has long been considered as an important safety-related substance. In this review, we summarizes the research progress on the toxicology of 5-HMF as well as the content and standards of 5-HMF in TCMIs.Therein, both literature summary and analysis results indicate that there are lack of toxicology researches of 5-HMF and its metabolites in TCMIs, although the potential toxicity of 5-HMF and its metabolites has been reported. Moreover, the content of 5-HMF largely varies from TCMIs to TCMIs, and even in the same TCMIs from different factories. To ensure the clinical efficacy of TCMIs, it urgent to carry out the study of the toxicology of 5-HMF in TCMIs comprehensively and systematically, so as to set up a relatively uniform standard as well as to develop process quality control method.
