Objective To investigate the feasibility of diffusion-weighted(DWI) MRI on basis of the intravoxel incoherent motion (IVIM) in nasopharyngeal carcinoma (NPC),and the diagnostic value of pure molecular diffusion coefficient (D),perfusion-related diffusion coefficient (D *) and perfusion fraction (f) in first onset NPC.Methods From December 2011 to January 2013,40 consecutive patients (26 men,14 women; median age,52 years) with suspected NPC were examined on a 3.0 T MR scanner.DW imaging was performed by using a single-shot echo-planar sequence with 13 b-values (0,10,20,30,50,80,100,150,200,300,400,600,800 s/mm2).MR imaging was compared with endoscopy and biopsy for the detection of NPC.Mean interval time between MR imaging examination and subsequent nasopharyngeal biopsy was 3 days (range,0-11 days).The subjects were divided into 2 groups according to the pathological results,group A was subjects with NPC (17 men,9 women; median age,35) and group B was ones with nasopharyngeal chronic hyperplastic inflammation(NPH) (9 men,5 women; median age,35).The D,D * and f were measured and compared in patients with first onset NPC and nasopharyngeal hyperplasia (Mann-Whitney test).Results IVIM DWI was successful in 24/26 with NPC and 12/14 with NPH.D value was significantly lower in A group compared with B group [mean,(0.70 ± 0.13) ×10-3 mm2/s vs (0.78 ± 0.05) × 10-3 mm2/s ; U =2.05,P ＜ 0.05],as was f value [mean,(16.25 ±1.46) ％ vs (26.20 ± 3.90) ％ ; U =11.16,P ＜ 0.01].However,D* value was significantly higher in Agroupas compared with B group[mean,(161.8 ±23.56) × 10-3 mm2/s vs (55.28 ± 17.05) × 10-3 mm2/s; U =13.90,P ＜0.01].Conclusions IVIM DWI is a feasible technique for investigating first onset NPC and D value has a certain value in differentiating NPC and NPH.D* value has an important potential value in distinguishing benign and malignant NPC.

Objective To screen monoclonal antibodies (mAbs) for early diagnosis of invisive Aspergillus. Methods Monoclonal antibodies against different antigens of Aspergillus fumigatus were produced. The two pairs of combinations of monoclonal antibodies were selected accoring the distinct epitopes and double-antibody sandwich ELISA based on mAbs above were established. The sensitivity and specificity of the methods were analyzed by detecting culture supernatants of clinical isolates and environmental isolatesof Aspergillus. spp, Penicillium Marneffei, Candidas, and serum from animal models and patients. The epitopes recognized by mAbs were identified by immunobotting. Results A total of 32 hybridoma cell lines that stably produced MAbs were obtained. Two double- antibody sandwich ELISAs were established. One method was specific for 19 clinical isolates and environmental isolates of Aspergillus. spp, whereas the other one was specific for the clinical and environmental isolates of Aspergillus fumigatus without cross-reation with other Aspergillus. spp. For the same kind of medium of Aspergillus fumigatus, the sensitivity of the first method was 10 fold higher than the second method. Conclusions The specific mAbs for early diagnosis of invisive Aspergillus were obtained. Antigen recognized by the specific mAbs was mannoprotein with molecular weights of approximately 25 000-75 000. This antigen was potential early diagnostic marker for invasive Aspergillus.

Objective:To compare the expression levels of absent in melanoma 2 (AIM2) inflammasome pathways in rheumatoid arthritis (RA) and osteoarthritis (OA) synovial specimens.Methods:Synovial tissue samples were collected from 41 RA and 26 OA patients, respectively. Horseradish peroxidase immunohi stochemical staining was used to detect AIM2 inflammasome pathway-related proteins, including AIM2, apoptosis-associated speck-like protein containing a CARD(ASC), caspase-1, and interleukin-1 (IL-1β). A semi-quantitative score (H-score) was performed according to the degree of positiveness. Correlation analysis between H-score results and clinical indicators of erythrocyte sedimentation tate (ESR) and C-reactive protein (CRP) were performed. The H score between RA and OA was analyzed by t test and Spearman correlation analysis were utilized for correlation analysis between H score and ESR and CRP.Results:The H scores of AIM2 protein in RA synovial tissues was (132±7) and (54±8) in OA synovial tissues ( t=7.42, P<0.01). The H scores of ASC protein in RA synovial tissues was (107±9) and (74±6) in OA synovial tissues ( t=2.36, P<0.05). The H scores of caspase-1 protein in RA synovial tissues was (99±5) and (74±10) in OA synovial tissues ( t=2.15, P<0.05). The H scores of IL-1β protein in RA synovial tissues was (118±11) and (76±7) in OA synovial tissues ( t=3.30, P<0.05) . In the correlation analysis, AIM2 was positively correlated with ESR [ r=0.74, P<0.01, 95% CI(0.38, 0.9)], and ASC was positively correlated with ESR [ r=0.5, P<0.05, 95% CI(0.16, 0.74)], IL-1β was positively correlated with ESR [ r=0.62, P<0.05, 95% CI (0.31, 0.81)], and the difference was statistically significant ( P<0.05). At the same time, AIM2 was positively correlated with CRP [ r=0.65, P<0.05, 95% CI(0.25, 0.86)]; ACS was positively correlated with CRP [ r=0.42, P<0.05, 95% CI(0.05, 0.69)]. IL-1β was positively correlated with C-reactive Protein [ r=0.41, P<0.05, 95% CI(0.05, 0.67)] and positively correlated with C-reactive protein, and the difference was statistically significant ( P<0.05). Conclusion::The expression of AIM2 inflammasome pathway-related proteins in RA synovium, including AIM2, ASC, caspase-1, and IL-1β, is higher than that of OA and are positively correlated with disease activity. Activation of AIM2 inflammasome pathway may be associated with the pathogenesis of RA disease activity.

Objective:To explore the difference of inflammatory factor imbalance between adolescent and adult patients with depression.Methods:A total of 30 adolescent and 30 adult patients with depression, and 30 adolescent and 30 adult healthy controls were included from January 2022 to August 2023. Interleukin-6 (IL-6), interleukin-17 (IL-17), transforming growth factor-beta1(TGF-β1), interleukin-10(IL-10) and Maresin-1(MaR1) level were detected by enzyme-linked immunosorbent assay. 24-item Hamilton depression scale (HAMD-24) was used to assess the severity of depression in all depressed patients. SPSS 26.0 statistical software was used for t-test, covariance analysis, Spearman analysis and multivariate binary logistic regression, and the predictive value of selected inflammatory factors in depression was evaluated by receiver operating characteristic(ROC) curve. Results:(1)In adolescent group, the levels of IL-6 ((64.000±38.632) pg/mL), IL-17((239.132±49.757) pg/mL), and TGF-β1((737.267±328.447)pg/mL) in patients with depression were higher than those in control group((32.396±16.330)pg/mL, (214.954±42.326)pg/mL, (454.542±297.194)pg/mL, all P<0.05), while the level of MaR1((21 381.301±3 946.011)pg/mL) was significantly lower than that in control group((30 130.138±10 278.999)pg/mL)( P<0.001). The level of IL-17 was positively correlated with the total score of HAMD-24 ( r=0.429) and the course of disease ( r=0.571), the level of IL-10 was negatively correlated with body weight factor score ( r=-0.384), and the levels of TGF-β1 was negatively correlated with anxiety/somatization factor score ( r=-0.449)(all P<0.05) in adolescent patients with depression.MaR1( B=0.000 1, OR=0.999 8, AUC=0.794, P<0.05) was an independent risk factor for adolescents depression.(2)In adult depression group, the levels of IL-6, IL-17, IL-10, TGF-β1 and MaR1 were higher than those in adult control group(all P<0.05). The level of TGF-β1 in adult depression group was negatively correlated with the total score of HAMD-24 ( r=-0.427), the score of anxiety/somatization factor ( r=-0.368), the score of blocking factor ( r=-0.405), and the score of hopelessness factor ( r=-0.398).The level of MaR1 was positively correlated with the age of onset of disease ( r=0.425)(all P<0.05) in adult patients with depression.MaR1( B=0.000 4, OR=1.000 3, AUC=0.874, P<0.001) and IL-6( B=0.040, OR=1.040 7, AUC=0.779, P<0.05) were independent risk factors for adult depression.The AUC of IL-6 combined with MaR1 was 0.938. Conclusion:There are differences in the underlying mechanism of immune imbalance between adolescent and adult patients with depression.MaR1 may be a diagnostic biomarker for depression in adolescents and adults.

The prevalence and recurrence rate of depressive disorder are high, while the recognition and cure rate are low. Early intervention can improve the quality of life of patients with depression. In clinical practice, it has been found that psychological treatments can effectively improve the symptoms and prognosis of depression.Cognitive behavior therapy(CBT) has been widely used in the treatment of depression, however, its mechanisms are still unclear. In this paper, the neuroimaging studies of patients with depression before and after CBT were summarized, and the structural or functional changes of different brain regions in patients with depression before and after CBT were described. The findings suggest that CBT improved depressive symptoms by increasing gray matter volume, activation level, and functional connectivity strength in the dorsolateral prefrontal cortex, reducing activation levels in the amygdala and parahippocampal gyrus, and restoring abnormal brain network activity or functional connectivity. Larger gray matter volume in anterior cingulate gyrus and higher activation levels in hippocampus and amygdala before treatment can effectively predict the effect of CBT in depressed patients. In the future, machine learning could be combined with brain imaging data to more accurately predict the effectiveness of CBT in treating depression.

Objective:To investigate the effect of the replantation in situ of donor skin graft with perforation and expansion in small and medium-sized skin transplantation. Methods:Patients were selected as group A with skin and soft tissue defects caused by various reasons treated in the Plastic and Aesthetic Surgery Department of Henan Provincial People’s Hospital from January 2002 to December 2019. A medium thick skin piece was harvested from the donor area with a drum dermatome, covering an area of 200-220 cm 2. The skin piece at the root of the drum dermatome was not broken, but the free skin piece of the drum dermatome was removed to the required area, transplanted to the wound surface, stitched intermittently and dressed with packing heap. The remaining skin graft in the donor area was punctured evenly with No. 15 surgical blade, then covered all the wounds in the donor area, sutured intermittently, and bandaged under pressure. The same kind of patients treated in other medical groups in our department in the same time were selected as group B. The skin donor area was not covered with skin graft in situ, but wrapped with traditional gauze. The patients were followed up in the outpatient department after operation, when the healing of the donor skin area and the degree of local scar was evaluated for data statistical analysis. The scars were scored according to Vancouver Scar Scale. The quantitative data were expressed in M( Q1, Q2), and were analyzed by Mann-Whitney U test. The qualitative data were analyzed by Chi-square test. P< 0.05 was statistically significant. Results:Group A had 63 cases, except for 1 case of graft avulsion, 2 cases of hematoma under the skin with partial survival of skin graft, 1 case of poor survival of infected skin graft after operation, the other skin grafts in the recipient area survived well. Group B included 59 patients, 38 males and 21 females, aged from 4 to 78 years old, with a skin defect area of 40 to 80 cm 2. The patients in both groups were followed up for 7-12 months. The healing time in group A was 11.1(10.2, 12.2) days. There were no skin pigmentation, severe hypertrophic scar and delayed healing of donor area. Four cases had mild scar hyperplasia and no keloid. The score of Vancouver Scar Scale was 3(2, 4). The healing time of group B was 15.8(13.9, 17.5) days with 23 cases of hypertrophic scar and 2 cases of keloid after healing. The score of Vancouver Scar Scale was 17(17, 17). There was significant difference in healing time between group A and group B ( P<0.01); there was significant difference in Vancouver Scar Scale scores between the two groups( P<0.01); what’s more, there was significant difference in the number of cases of hypertrophic scar between the two groups ( P<0.01). Conclusions:Compared with the traditional skin transplantation, the improved technology of the replantation in situ of donor skin graft with perforation and expansion has the advantages of intact skin, uniform thickness, timely blood circulation establishment after transplantation, no wound exposure in the donor area, natural skin color after primary healing, less scar and more in line with the skin function and aesthetic requirements of human body.
