Objective To discuss the application and significance of homocysteine (Hcy),renal function and serum lipid levels in renal transplantation,by testing those from patients after renal transplantation.Methods Hcy,creatinine (Cr),urea nitrogen (BUN),uric acid (UA),total cholesterol (TC),triglyceride (TG),low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were detected in transplantation group(n=63) and control group(n=60).Serum Hcy,Cr and BUN of transplantation group were continuously monitored before and 1,3,7,14 days after operation,and the relationship between Hcy and renal function before and after renal transplantation were compared.Results Compared with control group,Hcy,Cr and BUN in transplantation group all increased and the difference between two groups was statistically significant (P<0.05).Hcy,Cr and BUN in transplantation group all decreased after renal transplantation and the differences between two groups had statistical significance (P<0.05).Compared with that before surgery,Hcy,Cr and BUN in transplantation group gradually reduced 1,3,7 and 14 days after surgery,and the differences were statistically significant (P<0.05).Cr and BUN were positively correlated with Hcy (r=0.627,P<0.05).TC and LDL-C in transplantation group were higher than that in control group and the differences had statistical significance (P<0.05) while the difference of TG and HDL-C didn′t have statistical significance (P>0.05).Conclusion Hcy,Cr and BUN can be used as monitoring indicators of efficacy after renal transplantation,also which can be used to observe the incidence and severity of hyperlipidemia.

Objective To study family typology of stroke survivors′spouse and its relationship with perceived social support and offer a basic reference for family intervention. Methods A total of 327 qualified spouses of stroke survivors were investigated in the Family Cohesion and Adaptability Questionnaire (FACESII-CV) and Perceived Social Support Scale (PSSS) for their family typology proportion and relationship with PSSS. Results Compared with normal group, the ratios of extremity type family and middle family type were increased in this study: 23.9%(78/327)vs. 16.4%(20/122), 45.0%(147/327) vs. 29.5%(36/122), while the equilibrium family type were decreased:31.1% (102/327) vs. 54.1%(66/122), and there were significant differences (χ2=23.089, P<0.01). PSSS scores of spouses were (61.99±11.90) points, which included family support (21.71±4.27) points and social support (40.28±8.31) points. The scores were all in high level. Inter-comparison of three types of family showed the scores of PSSS were higher in extremity type families than those in middle and equilibrium type families: (68.27±11.27) points vs. (61.04±12.18), (59.56±10.34) points, and there were significant differences (F=5.636, P=0.005), but no significant difference between the last two (P > 0.05). Family typology was the most important factor to PSSS (β=0.212, P<0.05) in spouses of stroke survivors, followed by education degree of spouses (β=-0.190, P<0.05). There were no significant differences in the patients' spouses the baseline indicators in three types of families (P> 0.05). Conclusions Among the spouses of stroke survivors, the ratios of extremity and middle family type are increased but equilibrium family type are decreased. Family typology is the most important factor to PSSS of survivors′spouse. The PSSS of survivors′spouse in extremity type families is higher than that in middle and equilibrium type families. Intervention should be offered to the families, guiding the conversion of family typology from other types to extremity.

Objective: To investigate the regulation of curculigoside on osteogenic differentiation of MG63 and the protective effect on osteoporosis model mice. Methods: The effects of curculigoside on the survival rate of dexamethasone or H₂O₂ treated MG63 were detected by methyl thiazolyl tetrazolium (MTT). The specimens were divided into six groups: blank control group, blank administration group, model group (dexamethasone or H₂O₂ treatment group), low dose group (dexamethasone or H₂O₂+1.0 μmol/L curculigoside), medium dose group (dexamethasone or H₂O₂+2.5 μmol/L curculigoside) and high dose group (dexamethasone or H₂O₂+5.0 μmol/L curculigoside), the sample size of each group was 10. Western blotting was used to detect the expression of osteogenic differentiation-related proteins [type Ⅰ collagen, integrin β1, osteoblast-specific transcription factor (Osterix), osteocalcin and osteopontin] in MG63 cells after 1, 7 and 14 days incubated with 0, 1.0, 2.5 and 5.0 μmol/L of curculigoside. The sample size for each group at each time point was six. The experimental mice were divided into 4 groups: blank group, model group (dexamethasone treatment group), curculigoside low-dose group (dexamethasone+5 mg/kg curculigoside) and high-dose group (dexamethasone+45 mg/kg curculigoside), twenty each. After treatment, the tibia of the mice in each group were subjected to sacral HE staining. The number of osteoclasts was counted, and the levels of oxidative related factors in serum were determined by enzyme-linked immunosorbent assay (ELISA). Results: The MTT results showed that compared with the blank control group [(100±3.7)%], the cell survival rate decreased to (44.1±5.7)% after treatment with dexamethasone, and the survival rate increased to (79.7±3.8)% after treatment with 5.0 μmol/L of curculigoside. The cell survival rate decreased to (59.1±4.7)% after H₂O₂ treatment, and the survival rate increased to (80.8±3.5)% after treatment with 2.5 μmol/L of curculigoside. The results of Western blotting showed that the expression of type Ⅰ collagen and integrin β1 in MG63 cells was significantly increased after 1.0, 2.5 and 5.0 μmol/L of curculigoside for 1, 7 and 14 days compared with 0 μmol/L of curculigo side for the same period. After increasing (P<0.05), the expression of Osterix and osteocalcin was significantly increased after 1 day of incubation (P<0.05). However, compared with 0 μmol/L curculigoside treatment, the expression of osteopontin in MG63 cells was not significantly different after incubation with 1.0, 2.5, 5.0 μmol/L of curculigoside for 7 and 14 days (P>0.05). Compared with the blank group, the number of tibia osteoclasts in the osteoporosis model group increased. In the low-dose and high-dose groups of curculigoside, the tibia cortex was more continuous and the number of osteoclasts decreased. Compared with the blank group, the activity of oxygen in the osteoporosis model group was significantly increased (P<0.05), and superoxide dimutase and catalase were significantly decreased (P<0.05). Conclusions Curculigoside promotes the differentiation of MG63 cells by increasing the expression of osteoblast differentiation-related proteins, and has a certain therapeutic effect on dexamethasone-induced osteoporosis mice.

OBJECTIVE: To investigate the prevalence and related factors of emotional problems of newly identified patients with HIV/AIDS in Changsha, Hunan Province, and to provide scientific evidence for the mental health intervention in this special population. METHODS: A total of 370 patients with HIV/AIDS who were newly identified by the Center for Disease Prevention and Control in Changsha City from March 1, 2013 to February 28, 2014 were investigated. Self-designed questionnaire, Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), HIV/AIDS Stress Scale and Social Support Rating Scale (SSRS) were performed to assess the prevalence of depression, the anxiety symptoms, the HIV related stress and the status of social support. RESULTS: The prevalence of depression and anxiety were 40.3% (PHQ-9 ≥ 10 points) and 30.5% (GAD-7 ≥ 10 points), respectively. Severe depressive symptoms (PHQ-9≥20 points) and severe anxiety (GAD-7 ≥ 15 points) accounted for 8.1% and 14.3%, respectively. Hierarchical regression analysis showed that the status of employment (b=-3.407, P<0.001; b=-2.799, P=0.001), the sexual orientation (b=1.903, P=0.008; b=1.314, P=0.034), the resident status (b=-1.995, P=0.012; b=-2.167, P=0.002), the emergence of HIV-related symptoms(b=4.578, P<0.001; b=3.652, P<0.001) and the HIV related stress (b=0.081, P<0.001; b=0.090, P<0.001) were the predictors for both depressive and anxious emotional problems whereas the social support (b=-0.046, P=0.044) was the predictor for depressive emotional problems. Both anxiety (ΔR2=54.7%, P<0.001) and depression (ΔR2=55.8%, P<0.001) were strong predictors for patients with HIV/AIDS. CONCLUSION Depression and anxiety are prevalent among the newly identified patients with HIV/ AIDS. Psychosocial support and basic mental health services should be integrated into the current HIV/AIDS care system.

Background: No currently available biomarkers or treatment regimens fully meet therapeutic needs of type 1 diabetes mellitus (T1DM). Circular RNA (circRNA) is a recently identified class of stable noncoding RNA that have been documented as potential biomarkers for various diseases. Our objective was to identify and analyze plasma circRNAs altered in T1DM. Methods: We used microarray to screen differentially expressed plasma circRNAs in patients with new onset T1DM (n=3) and age-/gender-matched healthy controls (n=3). Then, we selected six candidates with highest fold-change and validated them by quantitative real-time polymerase chain reaction in independent human cohort samples (n=12). Bioinformatic tools were adopted to predict putative microRNAs (miRNAs) sponged by these validated circRNAs and their downstream messenger RNAs (mRNAs). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed to gain further insights into T1DM pathogenesis. Results: We identified 68 differentially expressed circRNAs, with 61 and seven being up- and downregulated respectively. Four of the six selected candidates were successfully validated. Curations of their predicted interacting miRNAs revealed critical roles in inflammation and pathogenesis of autoimmune disorders. Functional relations were visualized by a circRNA-miRNA-mRNA network. GO and KEGG analyses identified multiple inflammation-related processes that could be potentially associated with T1DM pathogenesis, including cytokine-cytokine receptor interaction, inflammatory mediator regulation of transient receptor potential channels and leukocyte activation involved in immune response. Conclusion Our study report, for the first time, a profile of differentially expressed plasma circRNAs in new onset T1DM. Further in silico annotations and bioinformatics analyses supported future application of circRNAs as novel biomarkers of T1DM.

Objective To identify the effect of stereotactic body radiation therapy (SBRT) on the survival of patients with recurrent pancreatic cancer after surgery.Methods The data of 104 patients with recurrent pancreatic cancer after surgery who underwent SBRT in the Department of Radiation Oncology of Changhai Hospital,Navy Medical University from February 2012 to December 2016 were retrospectively analyzed.The prescription doses ranged from 35-40 Gy/4-8 f.Survival analysis was performed using the Kaplan-Meier method,and relevant factors affecting patients' survival were screened by the Cox proportional hazards model.Results The median overall survival (OS) and progression free survival (PFS) was 12.5 (11.0-14.0) months and 7.3 (6.0-8.7) months,respectively,while the 1-year rate of OS and PFS was 55.8％ and 22.1％,respectively.Multivariate analysis indicated that tumor stage,biological effect dose (α/β =10,BED10),the decrease of CA19-9 level after treatment,and follow-up chemotherapy were all related factors affecting overall survival;tumor stage,BED10,the degree of pain relief and the decrease of CA19-9 level after treatment were related factors affecting PFS.Conclusions Patients suffering recurrent pancreatic cancer with early tumor stage,normal CA19-9 level and mild pain before treatment could be better treated by SBRT,BED10 ≥60 Gy and follow-up chemotherapy after radiotherapy can prolong the survival of patients.

Objective:To identify and screen the differential methylation genes in patients with cholangiocarcinoma and to predict the prognosis of patients with CCA.Methods:Cholangiocarcinoma tissues and paracancerous tissues of 8 patients with cholangiocarcinoma in Fujian Provincial Hospital from October 2019 to May 2020 were selected for 850K methylation sequencing analysis to obtain differentially methylated genes. The 2018 genome-wide methylation data and clinical information of 36 patients with cholangiocarcinoma were download from The Cancer Genome Atlas (TCGA) database, the 2012 cholangiocarcinoma methylation data (GSE32879) were download from the Gene Expression Omnibus (GEO) database, and the 2018 TCGA database differential survival genomic data of overall survival (OS) and disease-free survival (DFS) of cholangiocarcinoma were download from the GEPIA2 database. The differentially methylated positions (DMP) and differentially methylated regions (DMR) results of 850K methylation sequencing analysis of submitted samples, methylated genes in TCGA and GEO databases, and cholangiocarcinoma survival genes of samples were jointly submitted for testing, multi-data set analysis was performed by the Sangerbox VENN tool, and common differentially methylated genes were obtained by intersection screening. The minimum P value method was used to determine the cut-off value of gene expression in Sangerbox, and the patients were divided into high and low expression groups of differentially methylated genes. The OS, DFS, disease-specific survival (DSS), disease-free interval (DFI) and progression-free interval (PFI) of cholangiocarcinoma patients were compared between the two groups. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed. Results:A total of 121 954 DMP were identified by 850K methylation sequencing of cholangiocarcinoma tissues and paracancerous tissues of 8 patients; a total of 1 399 differentially methylated genes were identified in DMR, and the common prognosis related genes glucosaminyl (N-acetyl) transferase 1 (GCNT1) and neurotrophic receptor tyrosine kinase 3 (NTRK3) were identified by intersection identification. The expression of GCNT1 in the cholangiocarcinoma tissues was higher than that in the paracancerous tissues, and the difference was statistically significant ( P = 0.040). The expression of NTRK3 in cholangiocarcinoma tissues was higher than that in the paracancerous tissues, but the difference was not statistically significant ( P = 0.790). The minimum P value method was used to predict the prognosis of patients with cholangiocarcinoma based on the combined expression of GCNT1 and NTRK3, and the order was based on the sum of the expression levels of the two genes. When 30% of the ranking was taken as the cut-off value, the difference in DFS between the high expression group and the low expression group in cholangiocarcinoma was the most significant ( P < 0.001); there was no significant difference in OS between the two groups ( P = 0.065). The results of GO functional analysis showed that GCNT1 was involved in protein glycosylation, macromolecule glycosylation, glycosylation, glycoprotein biosynthetic process, glycoprotein metabolic process, transferase activity and transferring glycosyl groups, protein O-linked glycosylation, O-glycan processing, etc., and NTRK3 was involved in neurotrophin signaling pathway, Ras signaling pathway, EGFR tyrosine kinase inhibitor resistance, ErbB signaling pathway, phospholipase D signaling pathway, central carbon metabolism in cancer, natural killer cell mediated cytotoxicity, etc. The results of KEGG analysis showed that GCNT1 was mainly associated with system functions such as mucin-type O-glycan biosynthesis and metabolic pathways, and NTRK3 was mainly associated with cell surface receptor pathways, intracellular signal transduction, positive regulation of stimulatory responses, transmembrane receptor protein tyrosine kinase signaling pathway, enzyme-linked receptor protein signaling pathway, MAPK signaling pathway cascade and regulation, protein phosphorylation signal transduction and other system functions. Conclusions:The expressions of differentially methylated genes GCTNT1 and NTRK3 in cholangiocarcinoma have certain predictive effects on the prognosis of patients with cholangiocarcinoma.

Due to the reduction of patient cooperation and the limitation of clinical diseases, general practitioners lack effective acceptation training in the training process. To improve this situation, this study applies teacher standardized patients (TSP) combined case-based learning (CBL) to the acceptation ability training of general practitioners in medically unexplained physical symptoms (MUPS). And the acceptation ability and communication ability of 15 general practitioners were evaluated before, during and after the training. It shows that the application of "TSP + CBL" in the acceptation ability training of general practitioners in MUPS can effectively improve the acceptation ability and communication ability of general practitioners.

ObjectiveTo clarify the feasibility of the 3D scanning volume method for distal upper limb volume measurement, and to analyze its scorer reliability and criterion-related validity. MethodsFrom January to March, 2022, a therapist (operator A) who had not been exposed to 3D scanning volume method and water displacement method was trained to use a handheld 3D laser scanner and a spilt cup to measure the volume of a PVC distal upper limb model. The operation time of 30 operations of each method was recorded. The learning curves of the two methods were plotted using cumulative sum (CUSUM) analysis. The curve was cut into the learning stage and the mastery stage by the vertex of peak. The times required to reach the mastery stage and the operation time of the mastery stage for the two methods were recorded. A total of 20 healthy subjects were recruited from Huashan Hospital of Fudan University. Two trained therapists (operator A and operator B) measured the bilateral distal upper limb volume using a handheld 3D laser scanner, and operator A measured the bilateral distal upper limb volume using a spilt cup. ResultsThe fitting learning curve of the 3D scanning volume method (R² = 0.984) reached its peak after eight times of operation; while that of the water displacement method (R² = 0.494) reached its peak after five times of operation. At mastery stage, the operator spent less time using 3D scanning volume method than using water displacement method (P < 0.05). The intraclass correlation coefficient between the two operators were both 0.979 for bilateral distal upper limb volume measure (P < 0.001). The Pearson coefficients was above 0.979 between 3D scanning volume method and water displacement method (P < 0.001). ConclusionA therapist can master the use of the 3D scanning volume method after eight times of operation, and the operation time of 3D scanning volume method is shorter than that of water displacement method at mastery stage. The 3D scanning volume method is well reliable and valid, that can be used as an alternative to the water displacement method for distal upper limb volumetric measurement.
