The Short Form 36 Health Survey (SF-36) and Visual Analog Scale (VAS) scores of the two groups before treatment and at discharge were compared.Results:After the intervention, the SF-36 score and satisfaction of the intervention group were higher than those of the control group, and the VAS score was lower than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The application of MRT after ALND in breast cancer patients can improve the health of patients, increase patient satisfaction, and reduce their pain.

Objective: To explore the clinical applications of second generation colon capsule endoscopy (CCE-2). Methods: From July 2017 to December 2018, at the First Affiliated Hospital, College of Medicine, Zhejiang University, 40 outpatients and hospitalized patients who underwent CCE-2 examination were enrolled. The examination results were analyzed by an expert gastroenterologist with rich experience in small intestinal and colon capsule endoscopy. The stomach, small bowel and colon transit time, the score of colon cleansing quality, the completion rate of colon capsule examination, lesion detection and adverse effects were observed. Chi-square test and Student′t test were used for statistical analysis. Results: The whole gastrointestinal tract examination was completed during the capsule running time in 65.0% (26/40) of the patients. The average stomach transit time was (0.92±0.74) h, the small bowel transit time was (3.93±1.51) h and the colon transit time was (4.89±0.61) h. The capsule running time of patients who completed the whole gastrointestinal tract examination was shorter than that of patients who did not complete the whole gastrointestinal tract examination ((9.44 ± 3.53) h vs. (15.47±2.09) h), and the difference was statistically significant (t=6.79, P<0.01). The qualified rate of colon preparation was 67.5% (27/40). There were no statistically significant differences in colon transit time or capsule excretion time between patients with qualified colon preparation and poor colon preparation ((4.43±3.33) h vs. (5.96 ± 2.44) h; and (9.06 ± 3.91) h vs. (10.29±2.47) h; t=1.17 and 0.81, both P>0.05). A total of 33 (82.5%) patients had gastrointestinal lesions detected by colon capsule, including three cases of esophageal lesions (inflammation and mass), 21 cases of gastric lesions (chronic gastritis, mucosal protrusion, polyp and ulcer), nine cases of small bowel lesions (polyp, ulcer and vascular malformation) and 19 cases of colonic lesions (diverticulum, polyp, rectitis, mucosal erosion, ulcer and vascular malformation, internal hemorrhoids). Among them, there were 11 patients with two or more lesions. No adverse events occurred during the examination and all the capsules were excreted within 48 hours. Conclusion CCE-2 with high safety and good tolerance can be used for whole gastrointestinal tract examination.

OBJECTIVE: To explore the regulatory role of COX-2 and aggregation of EOS in the pathogenesis of Aspirin triad syndrome. METHOD: There were 34 patients with ST (group 1), 30 patients with chronic sinusitis and nasal polyps and asthma (group 2), 30 patients with sinusitis (control group). Nasal polyps of 94 patients were obtained in endoscopic sinus surgery,HE staining and immunohistochemical SP staining were performed to detect the distribution of eosinophils(EOS) and the expression of COX-2. Statistical analysis was performed using the SPSS software and then the relationship between their expression and distribution with clinical pathology and pathogenesis was analyzed. RESULT: EOS infiltrated extensively in nasal polyps, and EOS counts in these groups were 80.02 +/- 6.11, 76.62 +/- 5.22, 65.97 +/- 4.78,respectively. The difference between ST group, ATA group and control group are significant (P < 0.05), no significant difference between ST group and ATA group. COX-2 in the nasal polyps was mainly expressed in submucosal glands, glandular epithelial cells, epithelial cells, endothelial cells and EOS in interstitium. The positive cell count were 88.13 +/- 6.26, 89.46 +/- 5.97, 91.22 +/- 4.11, respectively. There was significant difference (P < 0.05) between ST group and control group. No significant difference (P > 0.05) was found between ATA group and control group,ST group and ATA group. CONCLUSION The difference of EOS infiltration in patients with ST may be associated with an inflammatory response underlying specific clinical manifestations after exposure to non-steroidal anti-inflammatory drugs, and the difference of COX-2 expression in patients with ST may be related to the conversion of metabolic pathway of arachidonic acid and the formation of nasal polyps.

Objective:To explore the changes and their clinical significance of plasma d-dimer (D-D) and fibrinogen (Fib) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with hypoxemia.Methods:150 patients with AECOPD admitted to our hospital from September 2017 to October 2018 were selected and divided into simple AECOPD group (75 cases) and AECOPD combined with hypoxemia group (75 cases) according to the arterial blood gas analysis results. In addition, 75 healthy people in the same period were selected as the control group. The D-D, Fib and C-reactive protein (CRP) level were detected in venous blood, and the differences and correlation of these indexes among the groups were statistically analyzed.Results:The D-D and Fib of AECOPD combined with hypoxemia group were significantly higher than those of AECOPD group and healthy control group, and the AECOPD group was higher than the healthy control group ( P<0.001). In AECOPD group, the plasma Fib and D-D were positively correlated with CRP ( r=0.617, P<0.001; r=0.300, P=0.009), but not with platelets (PLT) and white blood cell (WBC) ( P>0.05); in AECOPD combined with hypoxemia group, the plasma Fib was positively correlated with CRP, WBC and PLT ( r=0.854, P<0.001; r=0.345, P=0.002; r=0.272, P=0.018), but there was no correlation between D-D and CRP, WBC and PLT ( P>0.05). Conclusions:The plasma level of D-D and Fib increase with the aggravation of chronic obstructive pulmonary disease (COPD). They could be considered as potential inflammatory markers for the assessment of inflammation in the progression of COPD.

Objective: To explore the relationship between depression, anxiety, stress and food addiction among primary and secondary school students in Yixing City, so as to provide reference and suggestions for maintaining healthy eating behavior and psychological health intervention and promotion among primary and secondary school students in Yixing City. Methods: From December 2022 to February 2023, a stratified cluster random sampling method was used to select 4 180 primary and secondary school students from four primary and secondary schools in Yixing City, Jiangsu Province. A questionnaire survey was conducted using the Depression Anxiety Stress Scale-21 (DASS-21) and related behavior questionnaires. The data was analyzed using χ 2 test, Wilcoxon, Kruskal Wallis H rank sum test, and binary Logistic regression. Results: The prevalence of food addiction among primary and secondary school students in Yixing City was 0.98% (41 students), and there was no statistically significant difference in the comparison of food addiction, depression, anxiety, and stress scores among students of different genders and age groups ( Z/H = -1.34- 5.74, P >0.05). There was a positive correlation between food addiction and binge eating behavior, depression, anxiety, and stress symptoms ( r=0.14-0.23, P <0.01). The results of binary Logistic regression showed that anxiety ( OR=5.68, 95%CI =1.74- 18.55 ) and stress ( OR=5.41, 95%CI =2.20-13.32) were positively correlated with the occurrence of food addiction in primary and secondary school students ( P <0.01). Conclusions The risk of food addiction among primary and secondary school students with anxiety and stress symptoms is higher than that of the general population. Guidance and intervention on student mental health should cover the entire compulsory education and high school period, in order to improve the mental health level of students and reduce the occurrence of food addiction behavior.

Objective:To explore effects of multidisciplinary collaborative continuous care based on WeChat platform on peri-implant tissue of patients with periodontitis.Methods:Stratified sampling was used to select 100 patients with chronic periodontitis who underwent periodontal treatment in Stomatology Center of Shenzhen People's Hospital from March 2019 to March 2020, and their periodontal status was stable and implant restoration was completed. According to admission time, they were divided into the observation group (50 cases, 82 implants) and the control group (50 cases, 78 implants) . The observation group was given continuous care mode of multidisciplinary cooperation based on WeChat platform, while the control group was carried out the conventional continuous care intervention. At 0, 3, 9 and 12 months after completion of implant restoration, the peri-implant index of patients in the two groups were evaluated, including plaque index, periodontal pocket depth and probing bleeding index.Results:Within 12 months after implant restoration, the plaque index of the observation group showed a decreasing trend, while that of the control group showed an increasing trend. At 6 and 12 months after repair, the plaque index of the observation group were lower than that of the control group, and the differences were statistically significant ( P<0.05) . Within 12 months of completion of implant restoration, the depth of periodontal pockets in both groups showed an increasing trend. At 3, 6, and 12 months after the restoration, the depth of periodontal pocket in the observation group were lower than that in the control group, and the differences were statistically significant ( P<0.05) . At 12 months after implant restoration, the exploratory bleeding index of the observation group and the control group was respectively 10.22 (0, 19.98) % and 34.23 (16.12, 43.23) %, and the difference between the two groups was statistically significant ( P<0.05) . Conclusions:Multidisciplinary collaborative continuous care based on the WeChat platform can effectively control various periodontal indexes of implants in patients with chronic periodontitis, maintain the health of periodontal tissues and help prevent the occurrence of peri-implantitis.

OBJECTIVETo detect mutation of GPR143 gene in a Chinese patient affected with ocular albinism.

METHODSPeripheral blood samples were collected from the proband and his parents. The coding regions of the GPR143 gene were subjected to PCR amplification and Sanger sequencing.

RESULTSA previously unreported mutation (c.758T>A) was found in exon 6 of the GPR143 gene in the proband and his mother. The same mutation was not found in his father. As predicted, the mutation has resulted in a stop codon, causing premature termination of protein translation.

CONCLUSIONA novel mutation of the GPR143 gene related to X-linked ocular albinism has been identified.
