ABSTRACT

INTRODUCTION: The objective was to investigate the risk factors for poor pain control in patients with herpes zoster (HZ)-associated neuropathic pain treated with drugs combined with nerve block therapy. Neuropathic pain commonly follows HZ. Nerve block therapy is the most commonly used clinical treatment for such pain, combining anti-inflammation and analgesia to prevent peripheral sensitization of nerve. METHODS: Using clinical practice data from a cohort study at our research center, we established a multivariate logistic regression model to investigate potential risk factors for poor control of zoster-associated pain (ZAP) treated with drugs plus nerve block therapy, including demographic characteristics, complications, laboratory tests, and characteristics of HZ attacks. RESULTS: Of the 429 patients with ZAP who received drugs plus nerve block therapy, 95 (22.14%) had poor pain control after treatment. The risk of poor pain control was closely related to presence of cancer (odds ratio (OR) 4.173, 95% confidence interval (CI) 1.342-12.970), numerical rating scale score on admission (OR 1.929, 95% CI 1.528-2.434), and red blood cell count (OR 0.560, 95% CI 0.328-0.954). Area under the receiver operator characteristic curve was 0.730. Goodness of fit (Hosmer-Lemeshow) was 0.874. CONCLUSIONS: The risk of poor pain control in patients with ZAP increased as a result of certain patient characteristics and complications, especially severe pain before treatment and cancer.

ABSTRACT

Purpose@#The aim of this study was to compare the efficacy of liver transplantation (LT) and liver resection (LR) for hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) and to investigate risk factors affecting prognosis. @*Materials and Methods@#A total of 94 HCC patients with PVTT type I (segmental PVTT) and PVTT type II (lobar PVTT) were involved and divided into LR (n=47) and LT groups (n=47). Recurrence-free survival (RFS) and overall survival (OS) were compared before and after inverse probability of treatment weighting (IPTW). Prognostic factors for RFS and OS were explored. @*Results@#Two treatment groups were well-balanced using IPTW. In the entire cohort, LT provided a better prognosis than LR. Among patients with PVTT type I, RFS was better with LT (p=0.039); OS was not different significantly between LT and LR (p=0.093). In subgroup analysis of PVTT type I patients with α-fetoprotein (AFP) levels >200 ng/mL, LT elicited significantly longer median RFS (18.0 months vs. 2.1 months, p=0.022) and relatively longer median OS time (23.6 months vs. 9.8 months, p=0.065). Among patients with PVTT type II, no significant differences in RFS and OS were found between LT and LR (p=0.115 and 0.335, respectively). Multivariate analyses showed treatment allocation (LR), tumor size (>5 cm), AFP and aspartate aminotransferase (AST) levels to be risk factors of RFS and treatment allocation (LR), AFP and AST as risk factors for OS. @*Conclusion@#LT appeared to afford a better prognosis for HCC with PVTT type I than LR, especially in patients with AFP levels >200 ng/mL.

ABSTRACT

Objective:To explore the predictive value of Red Blood Cell Distribution Width (RDW) in predicting the prognosis of patients with Extracorporeal Membrane Oxygenation (ECMO).Methods:The clinical data of patients undergoing ECMO admitted to Intensive Care Unit of Sichuan Provincial People’s Hospital from January 2015 to January 2020 were retrospectively analyzed. Patients were divided into the survival group and death group according to the prognosis during ICU hospitalization. The patients' basic data , acute physiology and chronic health score system Ⅱ (APACHE Ⅱ), RDW and activated partial thromboplastin time (APTT) at 72 hours after treatment with ECMO were compared between the two groups. Univariate and Logistic regression multivariate analyses were used to analyze the prognostic factors of patients with ECMO, predictive models and death warning scores were established. The receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficacy of RDW and death warning scores for the prognosis of patients with ECMO.Results:A total of 71 patients with ECMO who met the inclusion criteria were included, including 38 patients in the death group and 33 patients in the survival group. The age, APACHE-Ⅱscore, 72 h RDW and 72 h APTT in the death group were higher than those in the survival group. Respectively, the hospitalization time of ICU in the death group was significantly lower than that in the survival group ( P< 0.05). Logistic regression analysis showed that APACHE-Ⅱscore ( OR=1.117, P=0.047)、72 h RDW( OR=1.102, P=0.029) and 72 h APTT ( OR=1.049, P=0.029) were independent risk factors for death in patients with ECMO. ROC curve analysis showed that the area under ROC curve (AUC) of the APACHE-Ⅱ, score 、72 h RDW and 72 h APTT were 0.691, 0.691 and 0.632( P<0.05), Respectively, the combined AUC was 0.764, the sensitivity was 0.526, and the specificity was 0.909. The death warning score of patients with ECMO was established according to the Predictive model , which is less than 2 points with low risk of death and more than 2 points with high risk of death. The area under the ROC curve of death warning score is 0.8, the sensitivity is 0.607 and the specificity is 0.923. Conclusions:The RDW at 72 hours after treatment with ECMO has a good value in predicting the prognosis of patients with ECMO. Besides, a greater predictive value for the prognosis of patients with ECMO by combining 72 hours RDW, 72 hours APTT with APACHE-Ⅱscore than that of any separate indicator.

ABSTRACT

Objective: To explore the risk factors of postoperative complications after radical gastrectomy + D2 lymphadenectomy and establish a predictive nomogram model. Methods: From July 2016 to June 2019, 1 705 patients who received radical gastrectomy + D2 lymphadenectomy in the Department of Gastrointestinal Surgery, Renji Hospital, Shanghai Jiao Tong University School of Medicine were collected. According to Clavien-Dindo grading system, the postoperative complications were graded, and the risk factors of postoperative complications ≥grade Ⅱ were analyzed by χ2 test. Multivariate Logistic regression was used to analyze the independent risk factors of postoperative complications ≥grade Ⅱ. According to the selected independent risk factors, the nomogram model was established. For verification, above patients were used as the training set, and 612 patients undergoing the same operation in this department from July to December 2019 were used as the validation set. Results: A total of 416 (24.4%) gastric cancer patients had postoperative complications. Multivariate Logistic regression analysis showed that male (OR=1.507, P=0.002), age ≥60 years old (OR=1.962, P=0.001), maximum diameter of tumor ≥5 cm (OR=1.456, P=0.002) and total gastrectomy (OR=1.313, P=0.026) were independent risk factors for postoperative complications ≥ grade Ⅱ. Based on these independent risk factors, the nomogram was established and presented good discrimination and predictive consistency in training set and validation set. Conclusion: The nomogram based on these four independent risk factors has a good predictive performance in predicting postoperative complications after radical gastrectomy for gastric cancer, and has a certain clinical application and reference value.

ABSTRACT

OBJECTIVE@#To create a protocol that could be used to construct chemical information database from scientific literature quickly and automatically.@*METHODS@#Scientific literature, patents and technical reports from different chemical disciplines were collected and stored in PDF format as fundamental datasets. Chemical structures were transformed from published documents and images to machine-readable data by using the name conversion technology and optical structure recognition tool CLiDE. In the process of molecular structure information extraction, Markush structures were enumerated into well-defined monomer molecules by means of QueryTools in molecule editor ChemDraw. Document management software EndNote X8 was applied to acquire bibliographical references involving title, author, journal and year of publication. Text mining toolkit ChemDataExtractor was adopted to retrieve information that could be used to populate structured chemical database from figures, tables, and textual paragraphs. After this step, detailed manual revision and annotation were conducted in order to ensure the accuracy and completeness of the data. In addition to the literature data, computing simulation platform Pipeline Pilot 7.5 was utilized to calculate the physical and chemical properties and predict molecular attributes. Furthermore, open database ChEMBL was linked to fetch known bioactivities, such as indications and targets. After information extraction and data expansion, five separate metadata files were generated, including molecular structure data file, molecular information, bibliographical references, predictable attributes and known bioactivities. Canonical simplified molecular input line entry specification as primary key, metadata files were associated through common key nodes including molecular number and PDF number to construct an integrated chemical information database.@*RESULTS@#A reasonable construction protocol of chemical information database was created successfully. A total of 174 research articles and 25 reviews published in Marine Drugs from January 2015 to June 2016 collected as essential data source, and an elementary marine natural product database named PKU-MNPD was built in accordance with this protocol, which contained 3 262 molecules and 19 821 records.@*CONCLUSION@#This data aggregation protocol is of great help for the chemical information database construction in accuracy, comprehensiveness and efficiency based on original documents. The structured chemical information database can facilitate the access to medical intelligence and accelerate the transformation of scientific research achievements.

ABSTRACT

Our aim was to evaluate the occlusal force and therapeutic efficacy of the masseteric muscles after intramuscular injection of botulinum toxin A (BTX-A) for the treatment of patients with concurrent temporomandibular disorders (TMD) and bruxism. Thirty patients with TMD associated with bruxism were randomised into three groups (n=10 in each group), and treated by bilateral intramuscular injection of BTX-A into the masseter, placebo, or control. We used an occlusal force analysis system to collect several measures of occlusal force such as duration of biting and closing, the maximum occlusal force, and the distribution of occlusal force. The occlusal force in the intercuspid position was reduced in all three groups. There was a significant difference between the BTX-A and placebo groups (F(df=1)=8.08, p=0.01) but not between the control group and the other two(F(df=1)=4.34, p=0.047). The duration of occlusion was significantly increased in the BTX-A group after 3 months' treatment (t=4.07, p=0.003). The asymmetrical distribution of occlusal force was reduced in all three groups, but not significantly so (Levene's test F(df=2)=0.25, p=0.78,ANOVA F(df=2)=0.50, p=0.61). Treatment of TMD with BTX-A is effective in reducing the occlusal force, but psychological intervention plays an important part in treatment.

ABSTRACT

The present study was designed to synthesize and evaluate a series of benzylisoquinoline derivatives. These compounds were synthesized by Bischler-Napieralski cyclization to yield 1-benzyl-3,4-dihydroisoquinolines, and the products were obtained by reductions. All these compounds were identified by MS, (1)H NMR and (13)C NMR. The inhibitory activities on pancreatic lipase and preadipocyte proliferation for the synthesized compounds and alkaloids from Nulembo nucifera were assessed in vitro. Most of the compounds showed inhibitory activities on both pancreatic lipase and preadipocyte proliferation. Particularly, compounds 7p-7u and 9d-9f exhibited significant inhibitory activity on pancreatic lipase while compounds 7c, 7d, 7f, 7g, 7i, and 7j potently inhibited the proliferation of 3T3-L1 preadipocytes. Our results provided a basis for future evaluation and development of these compounds as leads for therapeutics for human diseases.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the features of methylation in the promoter region of glucose-6-phosphate dehydrogenase (G6PD) gene and the association between gene promoter methylation and G6PD deficiency.</p><p><b>METHODS</b>Fluorescent quantitative PCR was used to measure the mRNA expression of G6PD in 130 children with G6PD deficiency. Sixty-five children without G6PD deficiency served as the control group. The methylation-sensitive high-resolution melting curve analysis and bisulfite PCR sequencing were used to analyze gene promoter methylation in 22 children with G6PD deficiency and low G6PD mRNA expression. The G6PD gene promoter methylation was analyzed in 44 girls with normal G6PD mRNA expression (7 from G6PD deficiency group and 37 from control group).</p><p><b>RESULTS</b>Twenty-two (16.9%) children with G6PD deficiency had relatively low mRNA expression of G6PD; among whom, 16 boys showed no methylation, and 6 girls showed partial methylation. Among the 44 girls with normal G6PD mRNA expression, 40 showed partial methylation, and 4 showed no methylation (1 case in the G6PD group and 3 cases in the control group).</p><p><b>CONCLUSIONS</b>Gene promoter methylation is not associated with G6PD deficiency in boys. Girls have partial methylation or no methylation in the G6PD gene, suggesting that the methylation may be related to G6PD deficiency in girls.</p>

ABSTRACT

This study was aimed to investigate clinical features of Chinese metabolic syndrome (MS) subjects with normal urinary albumin to creatinine ratio (UACR) and to estimate independent correlation factor for UACR. Data were drawn from a cross-sectional survey in participants having MS. The patients with different grade of albuminuria were divided into 4 groups according to the value of UACR (<10, 10-20, 21-30, >30 mg/g). All underwent biochemical tests. Bioelectrical impedance body fat content, islet β-cell function and insulin sensitivity were measured. Multivariable linear regression models were applied to further determine association between UACR and clinical factors with adjustment. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), TG, fat mass, fat content and homeostasis model assessment for insulin resistance (HOMA-IR) were significantly higher in the group with UACR at 10-20 mg/g than those in the group with UACA lower than 10 mg/g (P<0.05). Multivariable linear regression showed that TG, HbA1c, waist-hip ratio (WHR) and SBP were independently associated with UACR. The patients with normal UACR had abnormal levels of MS components. The factors independently associated with UACR were TG, HbA1c, WHR and SBP.
