Objective To investigate the relationship between albumin/globulin ratio (AGR) and postoperative survival among patients with esophageal squamous cell carcinoma(ESCC) undergoing radical oesophagectomy, to establish an effective prognostic nomogram for ESCC and to provide a reference for prognosis prediction of ESCC. Methods From February 2014 to September 2017, 390 ESCC patients who underwent surgery were retrospectively enrolled from the tumor hospital in Fujian Province. The receiver operating characteristic curves(ROC) were applied to establish optimal cutoff points. Chi-square test was used to estimate the relationship between the AGR and the clinical features. Cox proportional hazards model was used to estimate the HR and 95% CI for the associations between AGR and Prognosis of ESCC patients. A nomogram model was established to predict the outcome of ESCC patients. Results The ROC demonstrated the best cutoff value for AGR was 1.16. A total of 356 patients were recruited in the final analysis, who were divided into the high AGR group (≥1.16) and the low AGR group (<1.16) by the best cutoff value. Both 1-year and 3-year survival rates in the high AGR group were higher than those detected in the low AGR group(all P<0.05). Multivariate analysis showed that the T stage, N stage, and AGR were independent prognostic factors of overall survival(all P<0.05). The HR of T stage was 1.87 (T3-T4 vs T1-T2, 95% CI: 1.04-3.35); The HR of N stage was1.89 (N+ vs N0, 95% CI: 1.13-3.17); The HR of AGR was 0.57(the high AGR group vs the low AGR group, 95%CI: 0.36-0.90). The concordance index(C-index) of the nomogram to predict overall survival was 0.68 (95% CI: 0.62-0.73,P<0. 001).Conclusions The AGR was an independent prognosis factor for operated ESCC patients. The prognosis of ESCC in the high AGR group was better than that in the low AGR group and the prognostic nomogram provides individualized risk estimate of survival in ESCC patients after surgery.

Objective To explore the effects of preoperative serum cancer antigen 19-9 (CA19-9) and neuron-specific enolase (NSE) on the prognosis of patients with esophageal squamous cell carcinoma (ESCC). Methods This prospective study enrolled 176 patients with ESCC. 2 test was used to analyze the relationship between CA19-9, NSE and general clinical features. Survival curves were estimated using Kaplan-Meier method and comparisons were performed using the log-rank test. The Cox proportional hazards model was performed for multivariate analyses of overall survival (OS) and disease free survival (DFS). Results The patients with both high CA19-9 and NSE had the poor prognosis compared with those had both low CA19-9 and NSE (OS: HR=2.310, 95% CI: 1.208-4.418; DFS:HR=2.354, 95% CI:1.265-4.381). Compared to the separate detection of the two markers, the combined detection of CA19-9 and NSE was more accurate in the prognosis prediction of patients with ESCC (OS:C-index=0.686; DFS:C-index=0.684). Conclusions Preoperative serum CA19-9 and NSE were risk factors for the prognosis of patients with ESCC. Combined detection had higher accuracy of prediction of prognosis in patients with ESCC.

The post-marketing re-evaluation of traditional Chinese medicine (TCM) is a crucial stage for drug evaluation. Due to the particularity of TCM, it is necessary to re-evaluate the effectiveness of certain Chinese medicines by studying and collecting the studies on safety of long-term/extensive populations under actual clinical application, in order to verify the effectiveness of post-marketing TCM. However, there is an absence in technical specifications for relevant clinical trials on re-evaluation of effectiveness at present. As a consequence, the preliminary technical specifications were drafted in this article, focusing on several perspectives related to the re-evaluation of post-marketing clinical effectiveness of TCM, including ethical protection, research plan formulation, real-world research methods, randomized controlled trial methods, research methods of clinical pharmacological mechanism, sublimation method of TCM theory and so on. The objective of writing this article is to provide general methodological guidance for the re-evaluation of TCM post-marketing effectiveness, so that the process and results of post-marketing re-evaluation of TCM can be more scientific and reasonable.

<p><b>OBJECTIVE</b>To observe the effects of Huannao Yicong Formula (, HYF) on learning and memory and it's regulating effect on γ-secretase related anterior pharynx defective 1 (APH-1), presenilin enhancer-2 (PEN-2) signaling pathway, so as to discuss and further clarify the mechanism of HYF on Alzheimer's disease.</p><p><b>METHODS</b>Sixty APP/PS1 transgenic mice, randomly allocated into 4 groups, the model group, the donepezil group (0.65 mg/kg), HYF low-dose group (HYF-L, 5.46 g/kg) and HYF high-dose group (HYF-H, 10.92 g/kg), 15 for each group. Another 15 C57BL/6J mice with the same age and same genetic background were allocated into the control group, proper dosage of drugs or distilled water were given by intragastric administration once daily for 12 weeks. After 12 weeks of administration, the learning and memory abilities of mice in each group was evaluated by the morris water maze test, amyloid precursor protein (APP), Aβand Aβlevels in hippocampus were detected by enzyme-linked immunosorbent assay, γ-secretase was detected by dual luciferase assaying, the levels of APH-1a, hypoxia-inducible factor 1α (HIF-1α), cAMP response element-binding protein (CREB) and PEN-2 and their mRNA expression was measured by Western blot and real-time polymerase chain reaction.</p><p><b>RESULTS</b>HYF can ameliorate learning and memory deficits in APP/PS1 transgenic mice by decreasing the escape latency, improving the number of platform crossing and swimming speed (P<0.01, P<0.05). HYF can decrease the levels of APP, Aβ, Aβand the activity of γ-secretase in hippocampus of Alzheimer's disease model mice. HYF can down-regulate the levels of CREB and PEN-2 and the expression of their mRNA.</p><p><b>CONCLUSION</b>HYF can improve the learning and memory ability by inhibiting the activity of γ-secretase through the CREB/PEN-2 signaling pathway, and this may be one of the therapeutic mechanisms of HYF in Alzheimer's disease.</p>

<p><b>BACKGROUND</b>Atopic dermatitis (AD) is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching. Most patients have personal and/or family history of atopic diseases. Several criteria have been proposed for the diagnosis of AD. Although the clinical features of childhood AD have been widely studied, there has been less large-scale study on adult/adolescent AD. The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczema/AD and to propose Chinese diagnostic criteria for adult/adolescent AD.</p><p><b>METHODS</b>A hospital-based study was performed. Forty-two dermatological centers participated in this study. Adult and adolescent patients (12 years and over) with chronic symmetrical eczema or AD were included in this study. Questionnaires were completed by both patients and investigators. The valid questionnaires were analyzed using EpiData 3.1 and SPSS 17.0 software.</p><p><b>RESULTS</b>A total of 2662 valid questionnaires were collected (1369 male and 1293 female). Of all 2662 patients, 2062 (77.5%) patients had the disease after 12 years old, while only 600 (22.5%) patients had the disease before 12 years old, suggesting late-onset eczema/AD is common. Two thousand one hundred and thirty-nine (80.4%) patients had the disease for more than 6 months. One thousand one hundred and forty-four (43.0%) patients had a personal and/or family history of atopic diseases. One thousand five hundred and forty-eight (58.2%) patients had an elevated total serum IgE and/or eosinophilia and/or positive allergen-specific IgE. Based on these clinical and laboratory features, we proposed Chinese criteria for adult/adolescent AD. Of all 2662 patients, 60.3% were satisfied with our criteria, while only 48.2% satisfied with Hanifin Rajka criteria and 32.7% satisfied with Williams criteria, suggesting a good sensitivity of our criteria in adult/adolescent AD patients.</p><p><b>CONCLUSION</b>Late-onset of eczema or AD is common. The clinical manifestations of AD are heterogeneous. We have proposed Chinese diagnostic criteria for adolescent and adult AD, which are simple and sensitive for diagnosis of adult/adolescent AD.</p>
