【Objective】 To investigate the practice and benefit of national standardized management of type 2 diabetes in Yulin City. 【Methods】 We recruited the adult type 2 diabetes patients who sought medical help at our hospital from May 2020 to October 2022 as subjects. We collected their basic information (sex and age); measured height, weight, waist and hip circumference, and blood pressure; calculated body mass index (BMI); and detected blood glucose, c-peptide, HbA1c, biomarkers, urinary microalbumin, sensory nerve conduction velocity of lower limbs, ABI, and subcutaneous and visceral fat at the time of MMC recruited and the end of six months. T test and Mann-Whitney U rank sum test were used for measurement data and χ² test or Fisher’s exact probability method for counting data to analyze the data. 【Results】 After 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, and visceral and subcutaneous fat in all the patients decreased, but the level of fasting c-peptide increased compared with the baseline (all P<0.05). Secondly, compared with the baseline, the control rate of HbA1c (35.21% vs. 13.71% ) and the comprehensive control rate (13.97% vs. 7.26% ) were both significantly increased at six months (P<0.05). Thirdly, after 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, TG, TC, and UA were decreased more, while the fasting c-peptide and postprandial c-peptide were increased more in the patients of the HbA1c standard group (HbA1c<7% ) than those of the non-standard group. 【Conclusion】 The multiple benefits of blood glucose, blood lipid, uric acid and islet function can be achieved by taking type 2 diabetes patients into MMC. Meanwhile, the rates of HbA1c control and comprehensively reaching the standard are significantly increased. Therefore, MMC can explore a new way for the management of type 2 diabetic patients in this area.

Objective:To explore the effect of group psychological counseling on the improvement of negative emotion and vision-related quality of life in patients with primary glaucoma during the perioperative period.Methods:A total of 96 patients who underwent primary glaucoma surgery in Ophthalmology Ward of Beijing Tongren Hospital were selected from June 2018 to December 2019 and they were divided into the intervention group ( n=48) and the control group ( n=48) by the random number table method. The control group was given routine care during the perioperative period of glaucoma, while the intervention group was given group psychological counseling on the basis of the control group. Self-Rating Anxiety Scale (SAS) , Self-Rating Depression Scale (SDS) and self-made Vision-related Quality of Life Questionnaire were used to evaluate the patients. Results:The SAS score of the intervention group and the control group before intervention was respectively (56.79±1.86) and (56.77±1.92) , and the difference was not statistically significant ( P>0.05) . After the intervention, SAS score of the intervention group and the control group was respectively (41.31±3.37) and (47.45±2.05) , and the difference was statistically significant ( P<0.01) . The SDS score of the intervention group and the control group before intervention was respectively (66.97±3.27) and (66.64±2.43) , and the difference was not statistically significant ( P>0.05) . After the intervention, SDS score of the intervention group and the control group was respectively (44.91±2.04) and (52.52±1.86) , and the difference was statistically significant ( P<0.01) . The sleep quality and self-care ability in the intervention group were better than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Group psychological counseling can help to reduce negative emotions of patients, improve their sleep quality and self-care ability and improve their quality of life.

Objective To investigate functional connectivity between the two hemispheres in patients with positive symptoms of schizophrenia using voxel-mirrored homotopic connectivity ( VMHC ) based on resting-state functional magnetic resonance imaging (rs-fMRI). Methods Eighteen patients with positive symptoms of schizophrenia and 22 healthy controls underwent the rs-fMRI. The whole brain VMHC was calculated in order to provide imaging basis for the study of the pathological mechanism of schizophrenia. Results Compared to the controls, VMHC values were decreased in the bilateral orbitofrontal cortex (t=-5.31, P<0.01), fusiform gyrus (t=-5.16, P<0.01), middle occipital gyrus (t=-5.31, P<0.01) in patients with positive symptoms of schizophrenia. Conclusion The functional coordination between homotopic brain regions is impaired in patients with positive symptoms of schizophrenia .

Objective? To explore the mental state of laryngeal carcinoma patients after total laryngectomy and to analyze its correlations with coping style and social support. Methods? From January 2017 to October 2017, we selected 36 laryngeal carcinoma patients with total laryngectomy in otolaryngology dead and neck surgery at Beijing Tongren Hospital, Capital Medical University as subjects by convenience sampling. All of the patients were investigated with the Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS), Medical Coping Modes Questionnaire (MCMQ) and Social Support Rating Scale (SSRS). A total of 36 questionnaires were sent out and 34 of them were collected. Results? Among 34 patients, the total scores of SAS and SDS were (45.38±10.27) and (50.32±11.82) respectively. The score of "avoidance" coping style of patients after total laryngectomy was higher than that of norm with a statistical difference (P＜ 0.05). Pearson correlation analysis showed that SAS and SDS were negatively correlated with the total score of social support (P＜0.05);SAS and SDS were positively correlated with the confrontation dimension of coping style (P＜0.05), and were negatively correlated with the avoidance dimension (P＜ 0.05). Conclusions? After total laryngectomy, patients are with high levela of anxiety and depression. Medical staff should guide patients to take correct coping styles after surgery to face diseases, and improve patients' social support to relieve patients' negative emotions and total laryngectomy,and to promote the rehabilitation of diseases.

Caenorhabditis elegans is a very important model organism in life sciences. C. elegans has been widely used in research on life sciences, especially in drug screening and the mechanism of drugs, thanks to some of their prominent characteristics, including a short life,short generation cycle, and easy culture and observation. Aging is a complex process, which is the result of multiple factors. There are mainly three types of anti-aging signal pathways in C. elegans, including insulin-insulin-like growth factor-1 signal pathway, diet-restricted signaling pathway and mitochondrial respiratory chain/ATP synthesis pathway. In this paper, we reviewed the aging models based on the above three signaling pathways and the progress in anti-aging drugs based on the above aging models. In addition, a number of C. elegans models of aging-related neurodegenerative diseases can be obtained by using transgenic or chemical mutagenesis. Thus, this paper reviewed the transgenic models of C. elegans associated with neurodegenerative diseases, including theα-synuclein transgenic model of Parkinson disease, theβ-amyloid deposition model of Alzheimer disease, and the polyQ of Huntington disease, and summa?rized the effective drugs based on the above disease models. This review will provide reference for the study of C. elegans in the future screening of anti-aging drugs and drug screening for the prevention and treatment of neurodegenerative diseases.

Objective To induce human umbilical cord mesenchymal stem cells (hUC-MSCs) to hair-cell like cells in the inner ear, using a two-step neural differentiation method.Methods The hUC-MSCs were obtained from human umbilical cords by tissue adherence culture,whose surface antigen CD29, CD34, CD44, CD45, CD90, HLA-ABC, and HLA-DR could be identified by flow cytometry.In the neural stem cells induced phase, the NSE positive cells were analyzed by microscope and immunohistochemistry.In the second stage, the expression of hair-cell like cells markers (Math1, MyosinⅦa, Brn3c) were tested by qRT-PCR and immunofluorescence method.Results The control group and the protocol group had little NSE after differentiation while the protocol B group presented a neurobiological structure and demonstrated a higher NSE positive ratio after 5 days' neural stem cells induction (P<0.05).Compared to the control group, the mRNA and protein level of Math1, MyosinⅦa, and Brn3c exhibited a significant increase in the differential group,which induced for 4 weeks in the hair-cell like cells in the inner ear's induced phase(P<0.05).Conclusion The two-stage induction (hUC-MSCs-neural stem cells-hair-cell like cells) could produce more MyosinⅦa,Brn3c and Math1,which may provide an appropriate way to treat sensorineural deafness.

Objective To explore the endoscopic features and careinoembryonic antigen (CEA) ex-pressions of colorectal serrated adenomas (SA). Methods From June 2005 to July 2008, 27 patients with colorectal polyps and 26 cases of advanced colorectal cancer (ACC) were enrolled in the study. The pit pat-tern of the suspected lesions were observed with 0. 4% indigo carmine sodium stain and classified according to Kudo classification. The polyps were removed by biopsy, high-frequency electrical excision or endoscopic mucosa resection and the samples of ACC were collected with biopsy forceps. All specimens underwent rou-tine pathological examination and CEA expression was detected by immunohistochemistry. Results There were 47 SAs and 27 other types of polyps in polyp group. Most SAs located in left-side colon and were char-acterized by the bulge semipedunculation. The diameters of 45 serrated adenomas ranged from 3 to 8ram, and the maximal diameter of other 2 were more than 10ram. The most common type of pit pattern in SA was mixed type Ⅱ and ⅢL, with type Ⅱ predominant in a certain percentage. Expression of CEA in SA glands was significantly higher than that in proliferative polyps (P < 0. O1). Candnsion SA is an unique type of colorectal adenoma, which is capable of expressing CEA, and displays malignant potential and deserves great attention.
