Objective To evaluate the clinical efficacy and safety of endoscopic mucosal resection (EMR) assisted with magnifying chromoendoscopy in treatment of colorectal neoplasms. Methods Patients who met criteria for EMR including appropriate flat or depressed type and sessile lesions were enrolled. The association of morphology of colorectal lesions with histopathology was observed and the accuracy of estimation of invasive depth by magnifying chromoendoscopy was evaluated. Results Ninety lesions of 81 patients were reseeted by EMR (25 being sessile and 65 being flat or depressed). The histological results revealed low-grade dysplasia (LGD) in 58 lesions, high-grade dysplasia (HGD) in 20 lesions, and adenocarcinoma in 12 lesions. The average size of lesions was (1.4±0.5) cm in HGD, (1.6±0.5) cm in cancer and (1.0±0.4) cm in LGD with no significant difference (P> 0.05). It was shown that the flat and depressed lesions were more likely to be HGD or cancer as compared to sessile lesions, but with no statistical difference [41.5 % (27/65)vs. 20.0% (5/25), P= 0.084]. Moreover, the lesion with central depression was more likely to be HGD or cancer as compared to those without depressed surface [51.0% (25/49) vs. 17.1 % (7/41), P<0.01)]. The accuracy of estimating invasive depth by magnifying chromoendoscopy was 97.8% (86/90). Complete resection was confirmed histologically in 95.8% (88/90) of all lesions. Conclusions Colorectal lesions of depressed and flat types with central depression are more likely to be malignant. Estimation of invasive depth of colorectal neoplasia by magnifying chromoendoscopy in EMR treatment makes it more effective and safer.

Objective:To observe the effects of kidney-tonifying and mind-calming acupuncture therapy on sleep,mood,sex hormone levels,and traditional Chinese medicine(TCM)symptoms in patients with perimenopausal insomnia(PMI). Methods:A total of 90 patients with PMI were randomly divided into a treatment group and a control group,with 45 cases in each group.Patients in the treatment group were treated with acupuncture at Shenshu(BL23),Taixi(KI3),Baihui(GV20),and Anmian(Extra).The control group was treated with sham acupuncture.Both groups were treated 3 times a week for 4 weeks.Pittsburgh sleep quality index(PSQI)and insomnia severity index(ISI)were used to evaluate the sleep quality of the subjects before treatment,after treatment,and 1 month after treatment(follow-up).Beck depression inventory(BDI)and Beck anxiety inventory(BAI)were used to evaluate the depression and anxiety of the subjects before treatment,after treatment,and at 1-month follow-up.The TCM symptom scale was used to evaluate the TCM symptoms of the subjects before treatment,after treatment,and 1 month after treatment.Serum levels of estradiol(E2),follicle-stimulating hormone(FSH),and luteinizing hormone(LH)were measured before and after treatment. Results:During the study,2 cases dropped out of the treatment group,and no cases dropped out of the control group.The PSQI scores of the treatment group were significantly lower after treatment and at 1-month follow-up compared with those before treatment(P<0.05),and the difference was statistically significant compared with that of the control group(P<0.05).In the control group,the PSQI score was significantly lower after treatment compared with before treatment(P<0.05),and the difference was not statistically significant at 1-month follow-up compared with before treatment(P>0.05).Compared with the pre-treatment,the ISI,BDI,BAI,and TCM symptom scale scores of the treatment group were lower after treatment and at 1-month follow-up(P<0.05),and the differences with the control group at the same time point were statistically significant(P<0.05).The differences in ISI,BDI,BAI,and TCM symptom scale scores of the control group before treatment,after treatment,and at 1-month follow-up were not statistically significant(P>0.05).After treatment,the serum E2 level in the treatment group was significantly higher than that before treatment(P<0.05),and the difference with the control group was statistically significant(P<0.05).The difference in the serum E2 level before and after treatment in the control group was not statistically significant(P>0.05).The differences in the serum FSH and LH levels between before and after treatment were not statistically significant in either group of subjects(P>0.05). Conclusion:Kidney-tonifying and mind-calming acupuncture therapy can improve sleep quality,relieve anxiety and depression,delay the decrease of serum E2 level,and improve related TCM symptoms in patients with PMI.

Background:Celiac disease has a wide range of clinical manifestations and a higher prevalence in women.Aims:To evaluate the differences in clinical characteristics in adult celiac disease patients with different genders.Methods:Adult patients(age≥18 years)diagnosed as celiac disease from July 2017 to July 2022 at the People's Hospital of Xinjiang Uygur Autonomous Region were included consecutively in the retrospective study.Comparisons of baseline demography,and clinical and pathological features between different genders were performed.Results:A total of 73 adult celiac disease patients were enrolled,19 were males and 54 were females,with the ratio of male to female being 1:2.84.The peak age group of onset was 30-59 years old,with an average age of(50.2±13.6)years for men and(43.5±13.2)years for women at diagnosis.There was no significant difference in the distribution of different age groups between men and women(P>0.05),but the proportion of women in 18-49 years age group and≥50 years age group were both higher than that of men with statistical significance(P<0.05).The most common gastrointestinal symptoms were chronic diarrhea(56.2%)and abdominal pain(56.2%),and anemia was the most common extraintestinal manifestation(50.7%),which was existed in 36.8%of males and 55.6%of females.Abdominal pain and nausea/vomiting were more common in females(all P<0.05),whereas no statistically significant differences were found between male and female groups in other gastrointestinal and extraintestinal manifestations,such as chronic diarrhea,flatulence,decreased appetite,weight loss,chronic fatigue,anemia,hypoproteinemia,osteoporosis/bone loss,etc(all P>0.05).The pathological grading of small intestinal biopsy was Marsh Ⅱin 6 cases,and Marsh Ⅲa,Ⅲb and Ⅲc in 14,23,and 30 cases,respectively.No statistically significant difference was observed in pathological grading between patients with different genders(P>0.05).Conclusions:There is a marked female predominance in adult celiac disease in Xinjiang Uygur Autonomous Region,and women were diagnosed at a younger age.Chronic diarrhea,abdominal pain and anemia present as the most common gastrointestinal and extraintestinal manifes-tations.Abdominal pain and nausea/vomiting are more common in women than in men.

This paper conducted research on biomechanical characteristics and biological activity of concavity-convex amniotic membrane (CCAM) and discussed its superiority as ocular surface repair material. Folding and compression with vacuum of fresh amniotic membrane were used to prepare CCAM. After cutting the striga of CCAM, sixteen CCAM tissue section were chosen at random to test their tensile strength using electronic universal testing machine. The bilayer amniotic membrane (BAM), the double-deck amniotic membrane (DAM) and the monolayer amniotic membrane (MAM) were as controls. The test parameters included yield strength, tensile strength, elongation at break, elastic modulus and so on. The cytokines of fresh amniotic membrane (FAM), MAM and CCAM were analyzed by radioimmunoassay method. The CCAM was obviously thicker than MAM and DAM. After 15 min in PBS, the CCAM tissue can recover the normal shape. The tensile strength and the elongation at break of CCAM were higher than those of the MAM and the DAM (P < 0.05). The elastic modulus of the CCAM was smaller than that of the MAM and the DAM (P < 0.05). The content of 10 cytokines [epidermal growth factor (EGF), fibroblast growth factor (FGF), b-fibroblast growth factor b-FGF, hepatocyte growth factor (HGF), transforming growth factor-beta (TGF-beta), insulin-like growth factor (IGF), platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), nerve growth factor (NGF), brain-derived nellrotrophic factor (BDNF), ciliary neurotrophic factor (CNTF)] of CCAM decreased significantly compared with the FAM and increased significantly compared with MAM and DAM in 6 cytokines (EGF, FGF, HGF, TGF-betap, PDGF, NGF; P < 0.05). The CCAM composites is thinner and has higher cytokine content than MAM, and better biomechanical properties than the MAM and the DAM, showing the superiority as ocular surface repair material.

This study was aimed to prepare the spraying agent of prescriptions of Miao nationality herb and investigate the effect of Miao nationality herbs spray for serum SOD, MDA, and expression of Fas and Caspase-3 mRNA in lung tissues of silica-treated rats. The healthy SD rats were divided into 5 groups. Silica dust suspension was used in the model establishment of 4 groups. After the model was successfully established, 3 groups were randomly selected and given glucocorticoids atomization inhalation, Miao nationality herbs spray, Miao nationality herbs spray combined with intragastric administration of herbal medicine, respectively. After 40-day treatment, water-solubletetrazolium salt (WST-1) was used in the detection of serum superoxide dismutase (SOD). Thiobarbituric acid (TBA) was used in the detection of malondialdehyde (MDA). The mRNA expression variance of the Fas and Caspase-3 were detected by RT-PCR. The results showed that compared with the silica dust suspension group, the SOD activity of serum in the Miao nationality herbs spray group was significantly increased (P< 0.05). MDA content and the mRNA of Fas and Caspase-3 were significantly lower in the Miao nationality herbs spray group (P< 0.05). It was concluded that Miao nationality herbs spray group was able to increase the SOD activity of serum, decrease MDA content, and obviously decrease the expression of Fas and Caspase-3 of lung tissues among silica dust suspension rats.

Objective To observe the distribution of different types of Helicobacter pylori (H.pylori)infection in non-atrophic gastritis,atrophic gastritis and intestinal metaplasia.Methods From January 2015 to January 2017,457 hospitalized patients with gastritis were collected.All the inpatients received 14C-urea breath test(14C-UBT), H.pylori antibody typing detection, anesthesia gastroendoscopy and pathological analysis of biopsies.According to the results of H.pylori antibody typing,all patients were divided into typeⅠ H.pylori infection group,typeⅡ H.pylori infection group and H.pylori negative group.The relation among different types of H.pylori infection,age and pathological type were analyzed.Analysis of variance and chi-square test were performed for statistical analysis.Results The mean age of patients in typeⅠH.pylori infection group(n=135),typeⅡ H.pylori infection group(n=98)and H.pylori negative group(n=224)in patients with non-atrophic gastritis was(47.5 ± 9.0),(49.0 ± 9.0)and(52.0 ± 11.0)years,respectively, which were lower than those of patients with atrophy gastritis((56.8 ± 10.3),(57.5 ± 12.4)and(62.6 ± 10.4) years,respectively)and patients with intestinal metaplasia((59.2 ± 11.1),(57.5 ± 12.6)and(57.8 ± 10.0)years,respectively),and the differences were statistically significant(F=17.90,6.82 and 18.30,all P<0.01).The proportion of patients with non-atrophic gastritis in H.pylori negative group,typeⅡ H.pylori infection group and typeⅠ H.pylori infection group decreased in turn(56.3%,126/224;40.8%,40/98 and 34.8%,47/135, respectively),and the differences were statistically significant(χ2 =18.44,P<0.01).The proportion of patients with intestinal metaplasia in H.pylori negative group,type Ⅱ H.pylori infection group and type Ⅰ H.pylori infection group increased in turn(23.2%,52/224;26.5%,26/98 and 42.2%,57/135),and the difference was statistically significant(χ2 =11.44,P=0.003).There was no significant difference in the proportion of patients with atrophic gastritis among H.pylori negative group,type Ⅱ H.pylori infection group and type Ⅰ H.pylori infection group(20.5%,46/224;32.7%,32/98 and 23.0%,31/135;χ2 = 5.60,P=0.061).Conclusions Gastric atrophy is easily induced in patients with H.pylori infection.In patients without symptoms,H.pylori should be eradicated before gastric atrophy,which can provide the greatest benefit to the patients.Different types of H.pylori infection have different role in the progress of atrophic gastritis.TypeⅠ H.pylori infection accelerate the progress of atrophic gastritis,especially from atrophic gastritis to intestinal metaplasia,which should be actively eradicated.

Objective:To analyze the expression of 25-hydroxyvitamin D [25(OH)D] in serum and vitamin D receptor (VDR) in descending duodenum of adult patients with celiac disease and the correlation between 25 (OH) D, VDR and the clinical characteristics and indexes of celiac disease.Methods:From September 1, 2020 to May 1, 2022, 37 patients who were diagnosed with celiac disease (celiac disease group) in the Department of Gastroenterology of People′s Hospital of Xinjiang Uygur Autonomous Region were enrolled. During the same period, according to gender, age and nationality matched at a ratio of 1 to 1, 37 patients who visited the hospital with suspected symptoms of celiac disease and finally were excluded from the diagnosis of celiac disease after screening (non-celiac disease group) were selected. General data and clinical characteristics of all the patients were collected, including diarrhea, bone mineral density (BMD), Marsh stage. Serum 25(OH)D levels were detected, and the expression of VDR(high or low expression) in the descending duodenum was evaluated by immunohistochemical staining. Independent sample t test, chi-square test and Spearman correlation analysis were used for statistical analysis. Results:The serum 25(OH)D level and the proportion of patients with high VDR expression in the celiac disease group were both lower than those of the non-celiac disease group ((12.40±8.93) μg/L vs. (16.78±7.09) μg/L; 45.9%, 17/37 vs. 75.7%, 28/37), and the proportion of patients with diarrhea was higher than that of the non-celiac disease group (45.9%, 17/37 vs. 21.6%, 8/37), and the differences were statistically significant ( t=-2.52, χ2=6.86 and 4.89, all P<0.05). The serum 25(OH)D level was positively correlated with the VDR expression level in the descending duodenum both in the celiac disease group and the non-celiac disease group ( r=0.75 and 0.64, both P<0.001), and was not correlated with the diarrhea symptoms in the 2 groups (both P>0.05). There was a positive correlation between serum 25(OH)D and BMD in the celiac disease group ( r=0.48, P=0.017), and serum 25(OH)D was also correlated with BMD in the non-celiac disease group ( r=0.93, P<0.001). The VDR expression level in the descending duodenum was negatively correlated with the Marsh stage in the celiac disease group ( r=-0.36, P=0.031), while the VDR expression level was not related to the Marsh stage in the non-celiac disease group ( P>0.05). Conclusions:Vitamin D metabolism imbalance exists in the serum and duodenal mucosa of adult patients with celiac disease, which is related to the severity of osteoporosis and histopathology. It is suggested that patients with celiac disease should receive vitamin D metabolism regulation treatment.
