Objective To evaluate the effectiveness and safety of a transanal drainage tube(TDT) for decompression of acute left-sided obstruction of colorectum.Methods Fifty-seven patients with acute left-sided colorectal obstruction were enrolled in this study from January 2010 to December 2014.The obstruction location, property, success rate of insertion, one-procedure rate and complication rate were analyzed.Results There were 53 cases of primary colorectal cancer,among which lesions were located in the transverse colon in 1 case, in descending colon in 10, in sigmoid colon in 24,and in rectum in 18.There were 4other cases, one sigmoid colonic metastases of pulmonary cancer, 1 adhesive colonic obstruction after ovary surgery, 1 cervical cancer involved with rectum with stricture and obstruction, and 1 descending colonic obstruction caused by Crohn's Disease.TDT was successfully inserted in 55 cases(96.5％) without complications,in which 43 cases of primary colorectal cancer finally underwent surgery.TDT indwelled from 0 to 22days, for an average of (8.7± 4.4)d.Hartmann operation was performed in 9 patients,6 of which underwent sufficient lymphnode dissection.Among the 43 patients, one-stage operation was performed in 34 (79.1％),of which 30 cases underwent sufficient lymph node dissection, without stoma leakage.And the rest of 13 cases refused surgery because of poor prognosis and financial problems.One patient with Crohn's Disease refused surgery after TDT insertion and was discharged after palliation of distention.Conclusion TDT is safe and effective in decompressing acute left-sided benign obstruction with high success rate and low expenditure, and can achieve preoperative colonic lavage in one-stage operation for acute left-sided colorectal malignant obstruction.

Objective To study whether sulphur fumigation can cause changes to the content of imperatorin in Angelicae Dahuricae Radix (Baizhi).Methods The fresh samples of Angelicae Dahuricae Radix were collected from some cultivation bases. Half of each batch root was fumigated with sulfur according to the conventional method, and another half was cut into slices and dried naturally (i.e. without sulfur fumigation). The content of imperatorin was determined by HPLC on C18 column (4.6 mm×250 mm, 5μm) with a gradient mobile phase of acetonitrile-water solution system at the follow rate of 1.0 mL/min, 35℃ of the column temperature, and the max plot in 210-800 nm of the detective wavelength.ResultsTotally 29 batches of fresh roots ofAngelica dahurica were collected. The average contents of imperatorin were 0.202% in the Angelicae Dahuricae Radix with sulfur fumigation and 0.120% in the Angelicae Dahuricae Radix without sulfur fumigation. Compared with the corresponding samples without sulfur fumigation, the content of imperatorin in every Angelicae Dahuricae Radix with sulfur fumigation decreased by 6.77%-77.56% with an average decrease of 39.86%.Conclusion The content of imperatorin decreased significantly in every batch of Angelicae Dahuricae Radix with sulphur fumigation. It shows that the sulphur fumigation method was not suitable for producing and processing Angelicae Dahuricae Radix from fresh roots ofA. dahurica.

Objective To investigate the effect of dexmedetomidine on postoperative patient-controlled intravenous analgesia (PCIA) with sufentanil in patients with essential hypertension. Methods Sixty ASA Ⅱ or Ⅲ patients with essential hypertension aged 42-63 yr weighing 48-72 kg undergoing hysterectomy were randomly divided into 3 groups ( n = 20 each): control group ( group C) and different doses of dexrmedetomidine groups ( group D1.2 ). PCIA was performed with sufentanil 1 μg/ml + tropisetron 5 μg/ml in 100 ml of normal saline within 24 h after operation (background infusion at 2 ml/h with a bolus dose of 0.5 ml and a 15 min lockout interval). Dexmein group C. Ramsay score was recorded. The number of attempts, consumption of sufentanil, the number of patients who needed nifedipine or ephedrine and side effects such as vomiting and respiratory depression were recoded within 24 h after operation. The level of sedation was evaluated with Ramsay sedation score at 24 h after operation.Results Compared with group C, the number of attempts, consumption of sufentanil, the number of patients who needed nifedipine and incidences of vomiting and respiratory depression were significantly decreased, while Ramsay score was significantly increased in D1 and D2 groups, and the number of patients who needed ephedrine was significanlly increased in group D2 ( P ＜ 0.05). The number of attempts and consumption of sufentanil were significantly decreased, and Ramsay score and the number of patients who needed ephedrine were significantly increased in group D2 compared with group D1 ( P ＜ 0.05). Conclusion Dexmedetomidine can not only reduce the consumption of sufentanil for postoperative PCIA, but also prevent postoperative hypertension from deteriorating in patients with essential hypertension.

Objective To determine whether rTFPI could inhibit vascular thrombosis and salvage random pattern skin flaps following AIRC in rat models.Methods From April,2013 to June,2015,30 adult male Sprague-Dawley rats were randomized into 3 groups;a control group,an avulsion injury with roll compaction (AIRC) group,and an AIRC plus rTFPI therapy group.An 8.0 cm× 2.5 cm random flap was raised on the dorsum of each rat.The AIRC and AIRC plus rTFPI flaps were then altered with a device designed to simulate avulsion injury with roll compaction.After flap closure primarily,treatment was initiated immediately and continued for 3 days.Phosphate buffered saline was used in the control group and the AIRC group,while the AIRC plus rTFPI group received the recombinant Tissue Factor Pathway Inhibitor.Laser Doppler flowmetry and infra-red thermalgraphy were used on postoperative day three to assess nicrocirculatory blood flow and viability of the avulsed flaps.At postoperative day seven,final flap survival was determined.Using SPSS19.0 statistical analysis.Results The flap survival in AIRC group was only (32.7 ± 5.2)％ versus (62.5 ± 6.5)％ in control group,but the flap survival significantly increased (51.6 ± 8.2)％ after topical injecting rTFPI in experimental group.Statistically significant differences exist (P ＜ 0.05) between every two groups.The detection results of Laser-Doppler flowmetry and infra-red thermography showed that perfusion arrived the centre of the flaps in experimental group,while perfusion only arrived the proximal part of the flaps in the AIRC control group.Conclusion rTFPI therapy is effective in reducing ischemic necrosis of random pattern flaps following avulsion injury in the rat model.It suggests that rTFPI therapy may play an important role in clinical salvage of the failing avulsion injuries with roll compaction.

Objective To evaluate narrow?band imaging(NBI)for early esophageal cancer and pre?cancerous lesions. Methods A total of 170 patients ( 192 lesions) diagnosed as having superficial esophageal carcinoma and precancerous lesions by endoscopy were retrospectively analyzed. Clinical data of endoscopy, narrow?band imaging (NBI) and iodine chromoscopy were analyzed.Results The detection rates of early esophageal cancer were both 100?? 0% in NBI(13/ 13) and iodine staining (13/ 13), with no statisti?cally significant difference (P>0?? 05).The detection rate of high grade intraepithelial neoplasia in NBI and i?odine staining was 94?? 9% (94/ 99) and 100?? 0% (99/ 99) respectively with no statistically significant differ?ence (P>0?? 05); The detection rate of low grade intraepithelial neoplasia in iodine staining was 100?? 0%(80/ 80), significantly higher than that of NBI 78?? 8% (63/ 80) (P<0?? 01).Conclusion NBI and iodine staining endoscopy show better diagnostic value for early esophageal cancer and similar diagnostic value for high grade intraepithelial neoplasia in precancerous lesions. But for the low grade intraepithelial neoplasia, the diagnostic value of iodine staining endoscopy is better than that of NBI.

Nonalcoholic fatty liver disease is a group of diseases with unclear pathophysiological mechanism and is closely associated with metabolic syndrome. Bacterial components and metabolites produced by gut microbiota can regulate glucose and lipid metabolism, inflammatory response, and oxidative stress, and bile acids regulate immune function, energy metabolism, and material metabolism through various signaling pathways after activating their receptors. Gut microbiota and bile acids interact with each other through enterohepatic circulation, and the changes of their structure and function are involved in the development and progression of nonalcoholic fatty liver disease. This article reviews the effect of the homeostatic dysregulation of gut microbiota and bile acids and their interactions on nonalcoholic fatty liver disease.

ObjectiveTo investigate the value of albumin-bilirubin (ALBI) score in predicting the prognosis of cirrhotic patients with esophagogastric variceal bleeding, and to identify risk stratification and increase clinical applicability. MethodsA retrospective analysis was performed for the clinical data of 273 cirrhotic patients with esophagogastric variceal bleeding who were hospitalized in Subei People’s Hospital of Jiangsu from October 2012 to August 2018, and all patients received standard management after admission. Survival status was obtained through electronic medical records and telephone follow-up, and according to the prognosis in August 2020, the patients were divided into death group with 109 patients and survival group with 164 patients. General data were compared between the two groups. The Mann-Whitney U test was used for comparison of continuous variables between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical variables between two groups; univariate and multivariate Cox regression analyses were used to identify independent risk factors for prognosis. The Kaplan-Meier curve was used to analyze the survival rates of patients with different ALBI grades, and the log-rank test was used for comparison between groups; the receiver operating characteristic (ROC) curve was plotted to compare the ability of ALBI score, Child-Turcotte-Pugh (CTP) score, and Model for End-Stage Liver Disease (MELD) score in predicting short-term (6 weeks) and long-term prognoses. ResultsDuring follow-up, 109 patients (39.9%) died, and the death group had a significantly higher ALBI score than the survival group ［-1.49 (-1.82 to -1.11) vs -1.79 (-2.22 to -1.49), Z=5.630, P＜0.001］. The univariate analysis showed that age ≥55 years, hemoglobin ≤100 g/L, neutrophil count ≥3.4×109/L, platelet count ≤42×109/L, albumin ≤28 g/L, total bilirubin ≥21 μmol/L, alanine aminotransferase ≥42 U/L or aspartate aminotransferase ≥48 U/L, creatinine ≥94 μmol/L, serum sodium ≤137 mmol/L, international normalized ratio of prothrombin ≥1.5, ascites, and hepatic encephalopathy were risk factors for death in cirrhotic patients with esophagogastric variceal bleeding, and the patients with ALBI grade 3 had a significantly higher risk of death than those with ALBI grade 1 or 2; prophylactic ligation was a protective factor for survival improvement in cirrhotic patients with esophagogastric variceal bleeding (all P＜0.05). The multivariate analysis showed that age ≥55 years (hazard ratio ［HR］=2.531, 95% confidence interval ［CI］: 1.624-3.946, P＜0.001), creatinine ≥94 μmol/L (HR=1.935, 95% CI: 1.208-3.100, P=0.006), serum sodium ≤137 mmol/L ［HR=1.519, 95% CI: 1.015-2.274, P=0.042］, ascites (HR=1.641, 95% CI: 1.041-2.585, P=0.033), hepatic encephalopathy (HR=9.972, 95% CI: 3.961-25.106, P＜0.001), and ALBI grade 3 (HR=1591, 95% CI: 1.007-2.515, P=0.047) were independent risk factors for death. The patients with ALBI grade 3 had a significantly lower survival rate than those with ALBI grade 1 (χ2=18.691, P＜0.001) and ALBI grade 2 (χ2=21.364, P＜0.001), and the patients with ALBI grade 1 had a significantly higher survival rate than those with ALBI grade 2 (χ2=6513, P=0.011). The ROC curve analysis showed that ALBI score, CTP score, and MELD score had an area under the ROC curve (AUC) of 0770, 0.730, and 0.706, respectively, in predicting short-term (6 weeks) prognosis, and they had an AUC of 0.701, 0685, and 0659, respectively, in predicting long-term prognosis. ConclusionALBI score has a good value in predicting short-term (6 weeks) and long-term prognoses of cirrhotic patients with esophagogastric variceal bleeding, and the risk of death increases with ALBI grade. ALBI score can be used as an objective and simple model in clinical practice.

In recent years, the chimeric antigen receptor T-cell (CAR-T) therapy has achieved breakthrough progress in the treatment of hematologic malignancies. However, when it comes to solid tumors, numerous challenges persist.These include limited CAR-T cell infiltration, susceptibility to T cell exhaustion, off-target effects, and more.Thus, novel therapeutic strategies are imperative to enhance the efficacy of CAR-T therapy for solid tumors. In comparison to standalone CAR-T approaches, the combination of CAR-T with other tumor treatment modalities has demonstrated remarkable effectiveness in both preclinical and clinical research.This review article summarizes the advancements in combining CAR-T with various solid tumor treatments: antibody drugs, oncolytic viruses, tumor vaccines, and nanomedicines.The objective is to furnish a theoretical foundation and novel perspectives for the development of innovative CAR-T combination strategies tailored for solid tumor therapy.

Chronic myeloid leukemia (CML) is a malignant tumor formed by clonal proliferation of bone marrow hematopoietic stem cells. With the improvement of disease awareness and the introduction of new drugs, more than 90% of CML patients can achieve long-term survival. However, a few patients still show drug resistance. This article reviews the mechanism of drug resistance in CML patients treated with tyrosine kinase inhibitor (TKI) and the characteristics of ABL kinase region mutation.
