To investigate the effectiveness and safety of diverticular peroral endoscopic myotomy (D-POEM) for mid-esophageal diverticulum. Data of consecutive patients in the prospective database with mid-esophageal diverticulum who received D-POEM in West China Hospital, Sichuan University between April 2014 to September 2019 were collected. The modified Eckardt scoring system for mid-esophageal diverticulum was used to evaluate the severity of diverticular symptoms. The effectiveness and safety of D-POEM were evaluated in terms of clinical success, technical success, complications and recurrence. A total of 7 patients with mid-esophageal diverticulum were included. Clinical and technical success was achieved in all patients with operation time of 16-70 minutes. No serious complications (2 cases with minor complications) or recurrence occurred. The follow-up time was 2-16 months. The median modified Eckardt score decreased from 3 points before operation to 0 points after operation. It is preliminarily believed that D-POEM ensures a complete septotomy between normal esophageal lumen and esophageal diverticulum. It is a safe and effective technique for mid-esophageal diverticulum. The modified Eckardt scoring system is suitable for symptom evaluation before and after treatment of mid-esophageal diverticulum.

Objective: To investigate the clinicopathologic characteristics, immunophenotypes, and differential diagnostic features of extra-pleural solitary fibrous tumor (SFT) with uncommon histology. Methods: Seven cases of extra-pleural SFT with uncommon histology were collected during January 2015 and December 2016 in Zhejiang Provincal People′s Hospital; the clinical and radiologic features, histomorphology, immunophenotype and prognosis were analyzed. EnVision method was used for immunohistochemical staining of STAT6, CD34 and other differential diagnosis associated markers. Results: There were five male and two female patients, age from 23 to 54 years (mean=39 years). Three tumors were located in the soft tissue of head and neck, two in trunk subcutaneous soft tissue, one in sella region, and one in the kidney. Grossly the tumors ranged from 0.4 to 8.0 cm (mean=3.1 cm). Microscopically, all three head and neck cases resembled giant cell angiofibroma/giant cell subtype SFT, and one case showed sheet-like pattern of the multinucleated syncytial cells, creating a biphasic arrangement similar to myofibroma. Both truncal tumor resembled lipomatous type SFT, with one similar to dermatofibrosarcoma protuberans and the other to atypical spindle cell lipomatous tumor. The sella tumor showed morphology of a conventional SFT with high grade sarcomatous transformation. The renal tumor demonstrated a malignant SFT with entrapped benign renal tubules, mimicking a biphase synovial sarcoma or a malignant mixed epithelial and stromal tumor. By immunohistochemistry, all seven SFTs showed diffuse and strong nuclear reactivity to antibody against STAT6. Conclusions Extra-pleural SFTs show a significant heterogeneity of morphology and biological behavior which could cause differential confusion.Careful attention to its characteristic histomorphology with the use of STAT6 immunohistochemistry can help distinguish this tumor from its many mimickers.

Objective:To investigate the relationship between serum matrix metalloproteinase-9 (MMP-9) level and the location and severity of bleeding in patients with cerebral microbleeds(CMBs).Methods:A total of 60 CMBs patients admitted to the Department of Neurology of the First Affiliated Hospital of the Xinxiang Medical University from January 2019 to August 2020 were selected as subjects as the CMBs group, and 60 healthy controls without nervous system diseases in outpatient physical examination during the same period were selected as the control group. The clinical data and biochemical indicators of the two groups were collected. Serum MMP-9 levels were measured by enzyme linked immunosorbent assay (ELISA). According to susceptibility weighted imaging (SWI), CMBs patients were divided into grade 1 group ( n=24), grade 2 group ( n=19) and grade 3 group ( n=17), and according to the micro analytical rating scale (MARS), the CMBs patients were divided into the lobar group ( n=19), the deep or infratentorial group ( n=17) and the mixed group ( n=24).The relationship between serum MMP-9 level and the location and severity of CMBs was analyzed. SPSS 19.0 software was used for data statistical analysis.One-way ANOVA, t-test and rank sum test were used for comparison. Logistic regression analysis was used to analyze the influencing factors. Pearson correlation analysis and Spearman correlation analysis were used for correlation analysis. Results:The level of MMP-9 in CMBs group was significantly higher than that in control group (208.13(142.25, 285.88) μg/L, 149.50(93.40, 186.51)μg/L), and the difference was statistically significant ( P<0.05). Serum MMP-9 level was a risk factor of CMBs ( β=1.322, OR=3.750, 95% CI=2.038-7.997, P=0.002). The difference of level of MMP-9 in different severity of CMBs was statistically significant (147.55(109.25, 266.47)μg/L, 242.12(147.55, 288.80)μg/L, 270.42(203.43, 364.27)μg/L, P=0.017). Serum MMP-9 level was positively correlated with the number of CMBs ( r=0.371, P=0.003). The difference of MMP-9 level of CMBs in different locations were statistically significant (249.77(158.43, 338.46)μg/L, 188.83(138.52, 243.15)μg/L, 210.65(144.25, 255.78)μg/L, P=0.013). The increased serum MMP-9 level was a risk factor for CMBs( β=0.401, OR=1.122, 95% CI=1.004-1.204, P=0.036). Conclusion:The increased level of serum MMP-9 may be a risk factor of CMBs, especially for CMBs in cerebral lobesand, and the level of MMP-9 is positively correlated with the severity of CMBs.

Objective To investigate the prevalence of dyslipidemia in subjects with type 2 diabetes mellitus in Beijing urban communities.Methods Total 3316 subjects with type 2 diabetes (age 20-80 years) were recruited from 15 urban community health centers in Beijing using a multi-stage random sampling approach.Dyslipidemia was diagnosed according to Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults:2007 version.Results Among 3316 diabetic subjects (1329 malesand 1987 females),75.6％ (2506/3316) had dyslipidemia,the prevalence was 72.5％ (964/1329)in men and 77.6％ (1542/1987) in women.The prevalence of hypertriglyceridemia and hypercholesterolemia was 41.9％ (1388/3316) and 48.1％ (1595/3316),respectively.31.5％ (1043/3316) subjects had high levels of low-density lipoprotein cholesterol (LDL-C) and 21.2％ (703/3316) had low high-density lipoprotein cholesterol (HDL-C).Among all subjects with dyslipidemia only 22.9％ (575/2506) took hypolipid agents.The overall blood lipid control rates of triglyceride (TG),total cholesterol (TC),LDL-C and HDL-C in 1393 subjects with dyslipidemia history were 48.0％ (669/1393),17.4％ (242/1393),30.9％ (430/1393) and 75.8％ (1056/1393),respectively.Diabetics with dyslipidemia had higher body mass index,waist circumference,blood pressure,plasma glucose and hemoglobin A1c.The prevalence of dyslipidemia in the overweight and uncontrolled-glucose group were 79.0％ (1678/2125),78.9％ (1756/2227),respectively.Logistic regression analysis showed that gender,age,body mass index and hemoglobin A1c were associated with dyslipidemia.Conclusions The prevalence of dyslipidemia in diabetic subjects in Beijing urban communities is high and less than one quarter patients take hypolipid agents.Age,body mass index and hemoglobin A1c are the risk factors of dyslipidemia in type 2 diabetic patients.

Objective To study clinical characteristics of type 2 diabetic(T2D)patients with metabolic syndrome(MS)and its components in Beijing urban communities.Methods Totally,3295 T2D patients involved in a combined prospective diabetic management study from 15 urban communities in Beijing were classified as four groups, according to 2004 Chinese Diabetes Society's definition of MS, i. e, isolated T2D, T2D with one component of MS, T2D with two components of MS and T2D with three components of MS. Their clinical characteristics were analyzed. Results ( 1 ) Among 3295 T2D patients, 155 (4. 7% )were isolated T2D, 107 (32.6%) T2D with one component of MS, 1386 (42.1%) T2D with two components of MS and 679 (20.6%) T2D with three components of MS, with an overall 62.7% (2065/3295) of T2D patients complicated with MS. (2) In these T2D patients, the more components of MS they had, the higher body mass index (BMI), waist circumference, waist to hip circumference ratio (WHR),systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting serum levels of insulin and triglyceride (TG) and the lower level of high-density lipoprotein-cholesterol (HDL) were presented (P <0. 01 ). (3) Percentage of isolated T2D in women increased from 49. 0% (76/155) to 61.9% (420/679)of those with three components of MS ( P < 0 01 ), with increasing of components of MS. (4) Multiple logistic regression analysis showed that BMI, history of hypertension, decreased HDL, increased TG,increased blood pressure, all were risk factors for T2D patients complicated with MS. Conclusions Among T2D patients in urban communities of Beijing, 95.3% (3140/3295) of them complicated with one or more components of MS, and 61.9% (420/679) of them complicated with MS. So, community diabetic management must be implemented in an all-round way, including control of blood pressure, blood lipids,body weight and so on, in addition to control of blood sugar.

Objective To investigate current status of use of oral hypoglycemic drugs and insulin among adult patients with type 2 diabetes mellitus (T2DM) in urban community of Beijing.Methods In total,3297 T2DM patients aged more than 20 years from 15 urban communities of Beijing were studied.Their body weight,height,fasting plasma glucose level and glycosylated hemoglobin Alc (HbAlc) were measured.A door-to-door questionnaire survey on use of oral hypoglycemic drugs and insulin was conducted for them.All the T2DM patients surveyed were divided into four groups based on their received intervention.Results ①Of 3279 T2DM patients,454 (13.8％) received lifestyle intervention,971 (29.5％) used only one oral hypoglycemic drug,1179 (35.7％) with combined oral hypoglycemic drugs,and 693(21.0％) with insulin.②There was significant difference in average HbAlc among the four groups of T2DM patients with lifestyle intervention,only one oral hypoglycemic drug,combined oral hypoglycemic drugs,and insulin,with HbAI c of (7.0 ± 1.9) ％,(7.1 ± 1.5) ％,(7.4 ± 1.5 ) ％,and (7.5 ± 1.5 ) ％for them,respectively ( F =15.1,P ＜ 0.01 ).Proportions of the T2DM patients with HbAlc equal to or higher than 7.0％ were 32.2％,39.4％,52.1％ and 59.5％ for the four groups,respectively ( x2 =117.7,P ＜ 0.01 ).③In the T2DM patients with lifestyle intervention,32.2％ (146/454) of them with HbA1 c equal to or higher than 7.0％ were untreated with any oral hypoglycemic drug.In those with only one oral hypoglycemic drug,39.4％ (383/971) of them with HbAlc equal to or higher than 7.0％ were not treated with combined oral hypoglycemic drugs and/or insulin.In those with combined oral hypoglycemic drugs,52.1％ (614/1079) of them with HbAlc equal to or higher than 7.0％ were not received combined insulin treatment.④ Fasting plasma glucose level,treatment strategies,postprandial 2-h blood glucose level and length of the illness were independent risk factors for HbAlc level equal to or higher than 7.0％,with odds ratio (OR) of 1.757,1.256,1.175 and 1.031,respectively.⑤ In 2843 T2DM patients with oral hypoglycemie drugs and/or insulin treatment,1494 (52.6％ ) received biguanides and 693 received (24.4％ )insulin,respectively.Conclusions More than half of adult patients with T2DM do not meet the target of glycemic control of HbAlc less than 7.0％ in urban communities of Beijing,due to not active use of oral hypoglycemic drugs,and not timely adoption of combined use of oral hypoglycemic drugs and insulin therapy.

Esophageal cancer is an aggressive malignancy with high morbidity and poor prognosis. Symptoms of early esophageal cancer are insidious and difficult to detect, while advanced esophageal obstruction, lesion infiltration and metastasis seriously affect patients’ quality of life. Early detection and treatment can help to increase the survival chance of patients. Recently, artificial intelligence (AI) has shown remarkable success in diagnosis of esophageal cancer, highlighting the great potential of new AI-assisted diagnostic modalities. This paper aims to review recent progress of AI in the diagnosis of esophageal cancer and to prospect its clinical application.

Esophageal cancer is a serious threat to the health of Chinese people. The key to solve this problem is early diagnosis and early treatment, and the most important method is endoscopic screening. The rapid development of artificial intelligence (AI) technology makes its application and research in the field of digestive endoscopy growing, and it is expected to become the "right-hand man" for endoscopists in the early diagnosis of esophageal cancer. Currently, the application of multimodal and multifunctional AI systems has achieved good performance in the diagnosis of superficial esophageal squamous cell carcinoma and precancerous lesions. This study summarized and reviewed the research progress of AI in the diagnosis of superficial esophageal squamous cell carcinoma and precancerous lesions, and also explored its development direction in the future.

Objective:To investigate the relationship between serum matrix metalloproteinase-9(MMP-9) level and vascular cognitive impairment with no dementia (VCIND) in patients with cerebral small vessel diseases (CSVD).Methods:A total of 374 patients with CSVD treated in the First Affiliated Hospital of Xinxiang Medical University from January 2016 to January 2020 were collected and 150 healthy subjects in the same period were used as general data of the control group. All subjects were detected for serum MMP-9 level using enzyme linked immunosorbent assay and received cognitive function scoring using Montreal cognitive assessment (MoCA). The 374 patients with CSVD were divided into the Group A(186 cases with vascular cognitive impairment with no dementia) and the Group B(188 cases without cognitive impairment). The general data, serum MMP-9 level and cognitive function score were compared among the three groups and the correlation between MMP-9 level and cognitive function was analyzed.Results:The MMP-9 levels of Groups A and B ( (335.10±105.10)μg/L, (261.62±80.32)μg/L) were higher than those of the control group ( (168.23±48.85)μg/L), and the MMP-9 level of Group A was higher than that of Group B ( P<0.05). The MoCA scores of Groups A and B ( (18.45±5.24), (28.31±1.52) ) were lower than those of the control group (29.49±0.90), and the MoCA scores of Group A were lower than those of Group B ( P<0.05). The serum MMP-9 level, a risk factor for VCIND in patients with CSVD ( β=1.505, OR=1.323, 95% CI=1.149-1.527, P<0.05), was negatively correlated with total score of MoCA scale, visual-spatial and executive function, naming, language, abstract thinking, delayed recall, and directive force factor score ( r=-0.299, r=-0.155, r=-0.383, r=-0.358, r=-0.192, r=-0.259, r=-0.246 respectively, all P<0.05). Conclusion:The increased level of MMP-9 may be a risk factor of VCIND in CSVD patients, and it is closely related to cognitive impairment.
