Cholangiocarcinoma is a bile duct adenocarcinoma derived from the bile duct epithelium. Current treatment strategies for cholangiocarcinoma include surgery, chemotherapy, and radiotherapy. Surgical treatment is the first choice for all subtypes of cholangiocarcinoma. However, cholangiocarcinoma has the characteristics of high malignancy, easy recurrence after surgery, and low 5-year survival rates. Recent studies have found that many traditional Chinese medicines exhibit excellent anti-tumor effects in the treatment of various cancers, including cholangiocarcinoma. These medicines have advantages, such as low prices and abundant reserves, and are considered as an effective and safe complementary and alternative therapy for the treatment of cholangiocarcinoma. This article aims to review the effects of traditional Chinese medicine on cholangiocarcinoma from different aspects and levels in recent years. Results will provide new ideas for the prevention and treatment of cholangiocarcinoma.

Objective:To establish a graded post management system for specialist nurses in medical institutions, so as to provide a reference for the selection, stratification, employment, and promotion of specialist nurses in China.Methods:Through literature review and brainstorming, the primary screening indicators of the graded post indicator management system for specialist nurses were constructed. Two rounds of Delphi method were used to consult 25 experts to construct the graded post management system for specialist nurses.Results:The effective recovery rates for two rounds of consultation were 100% and 96%, respectively, with expert authority coefficients of 0.86 and 0.89, and Kendall harmony coefficients of 0.31 and 0.54. The final establishment of a specialist nurses graded post management indicator system included 8 first level indicators, 31 second level indicators.Conclusions:The graded post management indicator system for specialist nurse could provide theoretical support for the management of specialist nurse. It was conducive to clarifying the admission standards and hierarchical framework for specialist nurses, standardizing the establishment of positions and responsibilities, and improving the competition and incentive mechanism.

Objective:To investigate the acute gastrointestinal injury (AGI) in patients with extracorporeal membrane oxygenation (ECMO) at the early stage of operation and its influencing factors.Methods:A total of 70 patients with ECMO who were hospitalized in the Emergency Care Unit of Guangxi Zhuang Autonomous Region People's Hospital from September 2020 to December 2021 were retrospectively analyzed, and a total of 70 patients with ECMO who were hospitalized in the emergency care unit of Guangxi Zhuang Autonomous Region People's Hospital from September 2020 to December 2021 were retrospectively analyzed. According to the 2012 guidelines of the European Society of Intensive Care Medicine on the classification of acute gastrointestinal injury in critically ill patients, the patients were divided into AGI group and non-AGI group. The incidence of acute gastrointestinal injury in the early stage was statistically analyzed, and the results of blood gas analysis during ECMO loading and ECMO parameters, hemodynamic indexes and biochemical indexes after ECMO transfer were statistically analyzed. To explore the influencing factors and independent risk factors of AGI in the early stage. In addition, 70 patients were divided into successful group and non-successful group according to whether they were successfully withdrawn. The occurrence of acute gastrointestinal injury between the two groups was compared, and the effect of acute gastrointestinal injury on ECMO patients was analyzed.Results:Among the 70 ECMO patients, the incidence of early AGI was 71.43% (50 cases), and the components of AGI Ⅰ, Ⅱ, Ⅲ and Ⅳ were 18.57% (13 cases), 41.43% (29 cases), 11.43% (8 cases) and 0% (0 cases), respectively. ① Univariate analysis showed that systolic blood pressure, diastolic blood pressure, mean arterial pressure (MAP), vasoactive drug index (VIS), pH, lactic acid and BMI were significantly different between AGI group and non-AGI group when ECMO was used ( P < 0.05). Logistic binary regression analysis showed that BMI was an independent risk factor for early AGI in ECMO patients (ROC area 0.657, 95% confidence interval 0.522-0.791 ( P < 0.05), and Yoden index 0.15). (3) The AGI composition ratio of the unsuccessful group was higher than that of the unsuccessful group ( P < 0.05). Conclusions:Patients with ECMO have a high incidence of AGI in the early stage, mainly occurring in grade I and Ⅱ. Systolic blood pressure, diastolic blood pressure, MAP, VIS, pH, lactic acid and BMI when ECMO is put on are influential factors for the early development of AGI in ECMO patients, among which BMI is an independent risk factor for the early development of AGI in ECMO patients. The occurrence of AGI reduces the probability of successful withdrawal in ECMO patients.

Objective:To investigate the recovery of renal function and its influencing factors in patients receiving extracorporeal membrane oxygenation (ECMO) support and complicated with acute kidney injury(AKI).Methods:This was a retrospective observational study. The clinical data of patients with ECMO support and AKI admitted to the Emergency intensive care unit of the People's Hospital of Guangxi Zhuang Autonomous Region from October 2019 to December 2021 were collected. The patients were divided into renal function recovery group and renal function non-recovery group according to the recovery of renal function after 28 days of ECMO. With renal function non-recovery at 28 days as the end point of the study, and the variables with significant differences in baseline were selected for stepwise backward regression to determine the independent risk factors. The receiver operator characteristic (ROC) curve was drawn, and the area under the curve (AUC) was used to evaluate the diagnostic value of independent risk factors.Results:A total of 40 patients were enrolled, of which 28 patients (70%) had recovery of renal function, and 12 patients (30%) did not have recovery of renal function. Stepwise backward multivariate logistic regression analysis showed that lactate level at ECMO initiation was an independent risk factor for non-recovery of renal function ( OR = 1.380, 95% CI: 1.096-1.738, P = 0.006). The ROC curve showed that the AUC and 95% CI were 0.863 (0.751-0.975), the sensitivity was 100%, and the specificity was 75%. Conclusion:Lactate level at ECMO initiation was an independent risk factor for non-recovery of renal function on 28 days after ECMO initiation among patients undergoing ECMO support complicated with AKI. Lactate has a high predictive value for the non-recovery of renal function.

Objective:To verify the accuracy of the Kyoto classification score of gastritis for the endoscopic prediction of the Helicobacter pylori( H. pylori)infection in Chinese population. Methods:From June 2020 to January 2021, at the Digestive Endoscopy Center of the First Affiliated Hospital of Zhejiang Chinese Medical University, the clinical data of 489 patients who underwent gastroscopy examination were collected and the gastric mucosal manifestations under white light endoscopy (including atrophy, intestinal metaplasia, widening of gastric fold, nodularity, diffuse redness, white sticky mucus, etc.) were recorded according to the Kyoto classification of gastritis. H. pylori infection of the patients was determined according to 13C-urea breath test, histopathological examination and anti- H. pylori antibody test. The Kyoto classification score of gastritis of each patient was calculated. The sensitivity, specificity and odds ratio( OR)(95% confidence interval(95% CI)) of various endoscopic appearances in prediction of H. pylori infection were analyzed. Chi-square test was used for statistical analysis. Results:Among the 489 patients, 246 patients had H. pylori infection and 243 patients did not have H. pylori infection. There were 242 patients with Kyoto gastritis score ≥ 2, among them 215 cases had H. pylori infection and 27 cases did not have H. pylori infection. The accuracy of Kyoto classification score of gastritis in predition of H. pylori infection was 88.14% (431/489). Among the five indexes of the Kyoto classification score of gastritis, there was no significant difference in the incidence of intestinal metaplasia between patients with H. pylori infection and patients without H. pylori infection ( P>0.05). The incidence rates of atrophy, widening of gastric fold, nodularity and diffuse redness were higher in patients with H. pylori infection than those in patients without H. pylori infection (68.3%, 140/205 vs. 31.7%, 65/205; 95.2%, 99/104 vs.4.8%, 5/104; 89.7%, 35/39, vs.10.3%, 4/39; 85.0%, 227/267 vs.15.0%, 40/267), and the differences were statistically significant ( χ2=45.68, 106.46, 26.37 and 283.48, all P<0.01). The sensitivity, specificity and OR (95% CI) of atrophy, widening of gastric fold, nodularity and diffuse redness in prediction of H. pylori infection were 56.91%, 73.25%, and 3.62 (2.47 to 5.29); 40.24%, 97.94% and 32.06 (12.76 to 80.57); 14.23%, 98.35%, 9.91 (3.47 to 28.35); and 92.28%, 83.54% and 60.63 (34.02 to 108.08), respectively. The sensitivity and specificity of atrophy in prediction of H. pylori infection were low, and the diagnostic efficacy was general. The incidence rates of white sticky mucus and spotty redness of the gastric fundus and body were higher in patients with H. pylori infection than those in patients without H. pylori infection (86.5%, 32/37 vs. 13.5%, 5/37; 86.9%, 146/168, vs. 13.1%, 22/168), and the differences were statistically significant ( χ2=20.96 and 137.12, both P<0.01). The sensitivity, specificity, and OR (95% CI) of the two indicators in prediction of H. pylori infection were 13.01%, 97.94% and 7.12 (2.72 to 18.60), and 59.35%, 90.95%and 14.67(8.84 to 24.34), respectively, and the diagnostic efficacy was ideal. Conclusions:The Kyoto classification score of gastritis used for the endoscopic prediction of H. pylori infection is suitable for Chinese population. However, from the perspective of individual indicator, the diagnostic efficiency of atrophy and intestinal metaplasia is unsatisfactory. At the same time, attention should be paid to whether there is sticky mucus or spotty redness of the gastric fundus and body.

Objective:To evaluate the relationship between preoperative levels of serum uric acid (SUA) and postoperative delirium (POD).Methods:Seven hundred and fifty patients of either sex, aged 50-90 yr, with American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective knee replacement under spinal-epidural anesthesia, were selected.Venous blood samples were collected before anesthesia and levels of SUA were determined by enzyme-coupled assay.L 3-4 was selected as the puncture space, and the cerebrospinal fluid (CSF) specimens were obtained from the subarachnoid space for determination of concentrations of β-amyloid 42, total tau (t-tau) and phosphorylated tau (p-tau) by enzyme-linked immunosorbent assay.The patients were divided into hyperuric acid group (group HS) and non-hyperuric acid group (group NS) according to clinical diagnostic criteria of hyperuricemia, and into POD group (group POD) and non-POD group (group NPOD) according to the occurrence of POD.Logistic regression was used to identify the risk factors for POD.The mediating effect of CSF biomarkers was analyzed.The efficacy of SUA and CSF biomarker concentrations in predicting POD was evaluated using the receiver operating characteristic curve. Results:A total of 699 patients were finally enrolled in the study, and the incidence of POD was 21.5%.The results of logistic regression analysis after adjusting for multiple confounding factors, such as age, sex, years of education, Mini-Mental State Examination score, smoking history, drinking history, hypertension and diabetes history, showed that increased concentrations of SUA and p-tau and t-tau in CSF were risk factors for POD ( P<0.05). The results of mediation analysis showed that the concentrations of p-tau and t-tau in CSF were the mediating factors of the relationship between SUA and POD, with mediating effects of 0.000 301 (95% confidence interval 0-0.000 152) and 0.000 236 (95% confidence interval 0-0.000 092), respectively, and the intermediary proportion were 14.9% and 11.7%, respectively.The area under the receiver operating characteristic curve of SUA in predicting POD was 0.774 ( P<0.05). Conclusions:Increased preoperative SUA is a risk factor for POD, and the accuracy of predicting POD is high, and concentrations of p-tau and t-tau in CSF are mediators of SUA affecting POD.

Objective: To investigate the influence of inhibiting expression of polyamine-modulated factor (PMF-1) on the antitumor effect of glucocorticoid dexamethasone (DEX) in human cervical cancer Caski cells. Methods: siRNAs which target human PMF-1 gene were designed and synthesized, and their effect on the expression of PMF-1 in Caski cells was evaluated by Western blotting. The PMF-1 down-regulated and control Caski cells were treated with DEX, and then the affect of PMF-1 down regulation on the sensitivity of the tumor cells to DEX was analyzed. MTT method was used to detect cell proliferation, flow cytometry was used to analyze cell cycle, Western blotting method was used to evaluate expression level of glucocorticoids receptor (GR), and HPLC was used to analyze intracellular polyamine content. Results: The transient transfection of Caski cells with siRNAwhich targets PMF-1 gene can significantly reduce the expression level of PMF-1 protein. Compared with the control cells, treating PMF-1 down-regulated Caski cells with DEX can more effectively inhibit cell proliferation（P<0.01), up regulate GR expression, arrest cell cycle at G2 stage（P<0.01), and also significantly reduce intracellular polyamine level（P<0.01). Conclusion：Inhibiting PMF-1 expression can enhance antitumor pharmacological activity of DEX against human cervical cancer cells, and the underlying mechanism may be related with enhanced cell cycle inhibition and decreased intracellular polyamine level.
