Résumé
Background/Aims@#We aimed to investigate the comfort, safety, and endoscopic visibility during esophagogastroduodenoscopy (EGD) afforded by a modified 4-hour semifluid and 2-hour water (“4+2”) fasting protocol. @*Methods@#In this parallel group, endoscopist-blinded, randomized controlled trial, outpatients undergoing unsedated diagnostic EGD from 10:30 AM to 12:00 PM were randomly assigned to either a “4+2” protocol group or a conventional fasting group. The participants’ comfort during the fasting period and procedure was measured using the visual analog scale, and mucosal visibility was measured by endoscopists using the total visibility score. Satisfaction was defined as a visual analog scale score of ≤3. The primary outcome was the participants’ comfort during fasting. @*Results@#One hundred and six and 108 participants were randomized to the “4+2” protocol and control groups, respectively. Participants’ comfort before EGD was significantly higher in the “4+2” protocol group measured by both the proportion of satisfaction (86.8% vs 63.9%, p=0.002) and the visual analog scale score (median [interquartile range]: 1.0 [1.0–2.0] vs 3.0 [1.0–4.0], p<0.001). The proportion of satisfaction during EGD also significantly improved (59.4% vs 45.4%, p=0.039) in the “4+2” protocol group. The total visibility score was unaffected by the fasting protocol (5.0 [4.0–5.0] vs 4.0 [4.0–5.0], p=0.266). No adverse events were observed during the study. @*Conclusions@#The “4+2” protocol was more comfortable and provided equal mucosal visibility and safety compared with conventional fasting for unsedated EGD.

Objective:To evaluate the value of endoclip-assisted and submucosal injection-assisted cannulation techniques for difficult cannulation during endoscopic retrograde cholangiopancreatography (ERCP).Methods:Data of 12 458 patients treated with ERCP for the first time in the First Affilated Hospital of Naval Medical University from June 2015 to September 2020 were retrospectively analyzed. Twenty eight (0.22%) were identified as difficult cannulation where metal clip- or submucosal injection-assisted cannulation was used. The selective cannulation success rate, intubation time and complication incidence of the two techniques in difficult cannulation patients were analyzed.Results:Difficult cannulation was performed in 18 males (64.3%) and 10 females (35.7%) with an age of 69.6±14.1 years assisted by metal clips or submucosal injection. Five cases (17.9%) were type Ⅱ, 5 cases (17.9%) type Ⅲ, and 18 cases (64.3%) type Ⅴ according to papilla classification. Sixteen patients (57.1%) received metal clip-assisted cannulation, and 12 cases (42.9%) submucosal injection-assisted cannulation. Twenty-five (89.3%) patients successfully underwent selective cannulation with the cannulation time of 9.9±4.3 min. One case (3.6%) of mild post-ERCP pancreatitis and 3 cases (10.7%) of post-ERCP hyperamylasemia occurred. No postoperative bleeding or perforation occurred. All patients were cured and discharged after conservative treatment.Conclusion:When selective cannulation is difficult due to poor papilla exposure or deflection, endoclip- or submucosal injection-assisted cannulation can effectively improve the successful selective cannulation rate during ERCP with low complication incidence, which is worth of clinical promotion.

OBJECTIVES@#To investigate the prevalence of diabetes mellitus (DM) among Uygur children in Hotan Prefecture of Xinjiang, China, as well as the factors influencing the development of DM.@*METHODS@#The cluster random sampling method was used to select 5 308 children, aged 4-18 years, from the middle and primary schools and kindergartens in Hotan Prefecture of Xinjiang. The survey methods included questionnaire survey and the measurement of height and weight. All subjects were tested for fasting fingertip blood glucose to investigate the prevalence of DM and impaired fasting glucose (IFG).@*RESULTS@#A total of 5 184 valid questionnaires were collected. Fourteen children (0.27%) were found to have DM, among whom 8 had type 1 DM, 2 had type 2 DM, and 4 had unclassified DM. Twenty-nine children (0.56%) were found to have IFG. There was no significant difference in the prevalence rate of DM and IFG between boys and girls (P>0.05). The prevalence rate of DM was 0.18% in the 4-<10 years group, 0.47% in the 10-<15 years group, and 0.07% in the 15-18 years group (P=0.072).The prevalence rate of IFG in the above three age groups was 0.18%, 0.94%, and 0.42%, respectively, with a significant difference among groups (P=0.007). The proportion of family history of DM and the proportion of overweight/obesity in children with DM were significantly higher than those in children without DM (P<0.05), while the proportion of children with DM who preferred coarse grains was significantly lower than that in children without DM (P<0.05).@*CONCLUSIONS@#The prevalence of DM and IFG in Uyghur children in Hotan Prefecture of Xinjiang is relatively low. There is no significant difference in the prevalence of DM among children of different genders or age groups, but the prevalence of IFG in children of different age groups is different. A family history of DM, overweight or obesity, and low intake of coarse grains might be associated with the development of DM.

Purpose@#An underlying factor for the failure of several clinical trials of anti-epidermal growth factor receptor (EGFR) therapies is the lack of an effective method to identify patients who overexpress EGFR protein. The quantitative dot blot method (QDB) was used to measure EGFR protein levels objectively, absolutely, and quantitatively. Its feasibility was evaluated for the prognosis of overall survival (OS) of patients with gastric cancer. @*Materials and Methods@#Slices of 2×5 μm from formalin-fixed paraffin-embedded gastric cancer specimens were used to extract total tissue lysates for QDB measurement. Absolutely quantitated EGFR protein levels were used for the Kaplan-Meier OS analysis. @*Results@#EGFR protein levels ranged from 0 to 772.6 pmol/g (n=246) for all gastric cancer patients. A poor correlation was observed between quantitated EGFR levels and immunohistochemistry scores with ρ=0.024 and P=0.717 in Spearman's correlation analysis. EGFR was identified as an independent negative prognostic biomarker for gastric cancer patients only through absolute quantitation, with a hazard ratio of 1.92 (95% confidence interval, 1.05–3.53; P=0.034) in multivariate Cox regression OS analysis. A cutoff of 208 pmol/g was proposed to stratify patients with a 3-year survival probability of 44% for patients with EGFR levels above the cutoff versus 68% for those below the cutoff based on KaplanMeier OS analysis (log rank test, P=0.002). @*Conclusions@#A QDB-based assay was developed for gastric cancer specimens to measure EGFR protein levels absolutely, quantitatively, and objectively. This assay should facilitate clinical trials aimed at evaluation of anti-EGFR therapies retrospectively and prospectively for gastric cancer.

Objective:To study the value of metastatic lymph node radio (rN) and pathological lymph node stage (pN) in evaluating the prognosis of patients after radical gastric cancer.Methods:The clinicopathological data of 491 patients who underwent radical gastrectomy in Tantai Yantaishan Hospital from Jan. 2013 to Dec. 2017 were retrospectively analyzed. X-tile software was used to group the metastatic lymph node radio by rN. According to the number of lymph node metastasis, pN stage was performed. The correlation between metastatic lymph node radio and other clinicopathological factors was assessed. The metastatic lymph node radio and the pathological lymph node stage in evaluating the prognosis of patients after radical gastric cancer were compared.Results:(1) X-tile analysis showed that the best cut-off values for the metastatic lymph node radio in this study were 0.14 (14%) and 0.63 (63%) . (2) According to the cut-off value, the 491 patients included in the study were divided into rN1 (256 cases) , rN2 (160 cases) , and rN3 (75 cases) three subgroups. The results of the analysis of differences showed that there were significant differencesbetween the groups in terms of tumor diameter, tumor location, surgical resection range, stage, lauren classification, degree of differentiation, pT, pN, vascular cancer emboulus, nerve invasion, and pathological TNM staging groups. (3) Comparison of rN and pN staging in evaluation of the prognosis of patients after radical gastric cancer: ①Kaplan-Meier survival analysis results showed that rN was better than pN. ② Both single factor and multivariate cox analysis showed that rN was an independent risk factor for the prognosis of gastric cancer. In univariate analysis, rN group HR=3.18 (95% CI 2.63-3.84, P<0.001) , pN stage HR=1.88 (95% CI 1.66-2.15, P<0.001) ; rN group HR=2.21 in multivariate analysis (95% CI 1.73-2.82, P<0.001) , pN staging HR=1.31 (95% CI 0.95-1.79, P=0.095) . ③The time-dependent ROC analysis showed that the prognostic ability of rN was better than pN staging before 52 months of postoperative follow-up, and pN staging was more advantageous after 52 months. ④The Lauren classification was used as a stratification factor for stratified analysis. The Kaplan-Meier survival curve indicated that rN was better than pN staging in intestinal, mixed and diffuse gastric cancer, and the AUC curve showed the prediction of rN in patients with mixed and diffuse gastric cancer was better than pN staging, while pN staging performance was slightly better in patients with intestinal gastric cancer. Conclusions:rN is an independent factor affecting the prognosis of patients after radical gastric cancer surgery. When judging the prognosis of patients within 52 months after radical gastric cancer, rN has a better prognostic value than pN. In patients with mixed and diffuse gastric cancer in the Lauren classification, rN shows better prognostic value.

Résumé
Background/Aims@#Single-balloon enteroscopy (SBE) has been widely used in diagnosing small bowel disease. We conducted this study to systematically appraise its technical and clinical performance. @*Methods@#Studies on SBE published by September 2018 were systematically searched. Technical and clinical performance data were collected and analyzed with descriptive or meta-analysis methods. @*Results@#In total, 54 articles incorporating 4,592 patients (6,036 procedures) were included. Regarding technical parameters, the pooled insertion depths (IDs) for anterograde and retrograde SBE were 209.2 cm and 98.1 cm, respectively. The pooled retrograde ID in Asian countries was significantly greater than that in Western countries (129.0 cm vs 81.1 cm, p<0.001). The pooled anterograde and retrograde procedure times were 57.6 minutes and 65.1 minutes, respectively.The total enteroscopy rate was 21.9%, with no significant difference between Asian and Western countries. Clinically, the pooled diagnostic yield of SBE was 62.3%. Obscure gastrointestinal bleeding (OGIB) was the most common indication (50.0%), with a diagnostic yield of 59.5%. Vascular lesions were the most common findings in Western OGIB patients (76.9%) but not in Asian ones (31.0%). The rates of severe and mild adverse events were 0.5% and 2.5%, respectively. @*Conclusions@#SBE is technically efficient and is clinically effective and safe, but total enteroscopy is relatively difficult to achieve with this technique. Etiologies of OGIB in Asian countries differ from those in Western countries.
Résumé
Common bile duct stones (CBDSs) are a common biliary tract disease, and endoscopic therapy is the first-line treatment modality for this disease; however, some CBDSs are difficult to remove by conventional endoscopic techniques and are thus called difficult CBDSs. Therapies for difficult CBDSs include endoscopic papillary large balloon dilation, mechanical lithotripsy, choledochoscopy-assisted lithotripsy, and extracorporeal shockwave lithotripsy. This article reviews the advances in the above mentioned techniques for the treatment of difficult CBDSs, including indications, clinical effect, and adverse events.

OBJECTIVE@#The purpose of this study was to assess the association between triglycerides (TG), total cholesterol (TC) at baseline, and type 2 diabetes mellitus (T2DM) incidence in a general Chinese population. Further, it aimed to evaluate the ability of TG and TC to predict T2DM incidence.@*METHODS@#Qingdao Diabetes Prevention Program participants recruited between 2006 and 2009 were followed up in 2012-2015. TG, TC, and T2DM status were measured. Cox proportional hazards models were used to estimate the association between TG, TC, and T2DM incidence. The receiver operating characteristic (ROC) curve was used to evaluate the ability of TG and TC to identify T2DM participants.@*RESULTS@#The incidence of T2DM significantly increased with TG in women and TC in both men and women (Ptrend 1.15 and > 1.23 mmol/L in men and women, respectively. For TC, they were > 5.17 and > 5.77 mmol/L in men and women, respectively. The area under the ROCs of TG and TC were 0.54 (0.51-0.57) and 0.55 (0.52-0.58), respectively, in men, and 0.60 (0.58-0.62) and 0.59 (0.56-0.61), respectively, in women.@*CONCLUSION@#Elevated TG and TC were risk factors for T2DM incidence. However, no predictive capacity was found for both factors to identify T2DM incidence in Chinese men and women. Hence, TG and TC levels in both Chinese men and women might be used for decreasing the incidence of T2DM but no clinical predictive capacity for T2DM.

Objective To study the proliferation and inflammatory phenotypes of human fibroblast-like synoviocytes (FLS) induced by tumor necrosis factor-α(TNF-α). Methods The rheumatoid arthritis (RA)-FLS were cultured in vitro, then treated with different concentrations of diallyl trisulfide (DATS). The proliferation activity was detected by CCK-8 method. Then TNF-α was used to stimulate the RA-FLS, mRNA and protein expression of interleukin (IL)-6, matrix metalloproteinases (MMP)-1 and vascular endothelial growth factor (VEGF) were detected by quantitative real time polymerase chain reaction (qPCR) and enzyme linked immunosorbent assay (ELISA). Differences among groups were determined by one-way analysis of variance (ANOVA), LSD-t test was used for comparison between 2 groups. Results RA-FLS was successfully is-olated and cultured in vitro. The positive rate of CD90 and CD29 in the RA-FLS was more than 90%. The proli-feration activity of RA-FLS treated with 100 μmoL/L, 200 μmol/L and 300 μmol/L DATS was (98.92 ± 0.40)%, (95.91±0.32)%, (94.05±0.24)%, respectively. As Compared with the normal control group, the pro-liferation activity of RA-FLS was lower, and the statistically significant difference is between normal control group 200 μmol/L and 300 μmol/L DATS (t=-4.46, P<0.05; t=-7.98, P<0.05). After TNF-α stimulation, the expression of IL-6's mRNA in experiment group (100μmol/L DATS) is higher compared with the model control group (t=5.74, P<0.05), but the change of IL-6's protein is no significant difference (t=-0.49, P=0.627). The differences of mRNA and protein expression levels of MMP-1 and VEGF between the experiment group (100μmol/L DATS) and the model control group were not statistically significant. The relative mRNA level [(0.42 ± 0.06), t=-23.47, P<0.05;(0.14±0.039), t=-36.59, P<0.05;(0.36±0.09), t=-13.1, P<0.05)] and the protein levels [(108.0±4.7) ng/L, t=-63.79, P<0.05, (26.0±1.0) ng/L, t=-9.68, P<0.05;(57.9±0.7), t=-34.59, P<0.05] of IL-6, MMP-1, VEGF in experiment group (200μmol/L DATS) were significantly decreased. And the relative mRNA level [(0.041 ±0.027), t=-38.48, P<0.05; (0.027 ±0.027), t=-41.22, P<0.05; (0.131 ±0.047), t=-17.74, P<0.05] and the protein levels [(24.2 ±2.3) ng/L , t=-88.69, P<0.05; (22.7 ±1.0) ng/L , t=-14.13, P<0.05; (34.5 ±1.7), t=-48.45, P<0.05] of IL-6, MMP-1, VEGF in the experiment group (300 μmol/L DATS) were also significantly decreased. The difference between the two groups was significant (t=-24.89, P<0.05; t=-4.45, P<0.05; t=-13.87, P<0.05). Conclusion DATS can inhibit the proliferation and the effect of TNF-αinduced secretion of IL-6, MMP-1 and VEGF in RA-FLS. The effect is dose-dependent.

OBJECTIVE: To construct a model for predicting the prognosis of esophageal cancer bone metastasis. METHODS: The clinical data of 183 patients with esophageal cancer bone metastasis were analyzed retrospectively, and the prognostic factors of patients were analyzed by log-rank method and Cox proportional hazard model. Nomogram was constructed with the accelerated failure-time model.RESULTS: The average survival time(10.0 months, 95% CI:7.758-12.338) of patients aged 28-70 years was longer than that of patients aged 71-91(6.4 months, 95% CI:4.365-8.428)(χ~2=4.077, P=0.043). The prognosis of unmarried patients(average 7.0 months) was worse than that of the married(10.5 months on average)(χ~2=12.841, P<0.001). As for prognoses of different pathological types, the differences between adenocarcinoma(average 10.2 months, 95% CI:7.797-12.548), squamous cell carcinoma(average 6.4 months,95%CI:3.895-8.899) and other types(average 4.0 months, 95% CI:4.000-4.000) were statistically significant(χ~2=7.171, P=0.028).There were also significant differences between the prognoses of patients with different T stage(χ~2=8.833, P=0.032). Nomogram was constructed with the risk factors above and the C-index reached 0.675(95%CI: 0.626-0.725). CONCLUSION: The prognosis of esophageal cancer bone metastasis was poor. Marriage, T stage, histological grade and pathological types were risk factors affecting prognosis, while N stage didn't appear to show obvious effect on prognosis. The nomogram was tested to have a good predictive capacity.

X-tile software was used to determine the best cut-off value of the age. Prognostic factors were analyzed with log-rank and Cox proportional hazard model by SPSS(v25.0). RESULTS: The median survival time of patients with esophageal cancer with brain metastasis was 7.0 months, the 6-month survival rate was 53.3%, and the 1-year survival rate was 16.3%. Only age(χ~2=4.045, P=0.044)was the prognostic factor, while there was insufficient evidence to show whether gender, marriage, race, primary site, histological grade,surgery, pathological type, T stage or N stage was associated with the prognosis of the patients. CONCLUSION: Brain metastasis is a rare metastatic type of esophageal cancer. Age is associated with worse prognosis, while the influences of other risk factors are not clear.Active treatment can lead to better prognosis.
