Objective:To observe the change of periphery and centra lymphocyte subsets at the crest-time of MOG_(35-55) induced EAE disease in mice,and to explore the alteration of cellular immunity and humoral immunity in the invasion process in EAE.Methods:MOG_(35-55) was used to establish EAE model in femina C57BL/6 mice.The behavioral changes and the histological scores were recorded after the mice were immuned .The changes of CD3~+CD4~+,CD3~+CD8~+,CD4~+CD25~+ and B220~+ on periphery and centra lymphocytes in spleen,brain and spinal cord were analyzed by flow cytometry.Results:The CD3~+CD4~+,CD3~+CD8~+,CD4~+CD25~+ and B220~+ lymphocytes were detected in the brain and spinal cord of EAE group mice,but they were not detected in CFA control group.The CD3~+CD4~+ and CD3+CD8+lymphocytes in the spleen of EAE crest-time group were lower than those in CFA control group(P＜0.05).The B220~+ lymphocytes were obviously higher than in the CFA control group (P＜0.01).And CD4~+CD25~+ lymphocytes were slight higher than the CFA control group.Conclusion:At the crest-time during EAE,the CD3~+CD4~+,CD3~+CD8~+lymphocytes of spleen reduced obviously,B220~+ lymphocytes increased markedly,and the CD4~+CD25~+ lymphocytes just have the increasing trend.It indicates that cellular immunity and humoral immunity coregulated the patho-process at the crest-time of EAE,T lymphocytes and B lymphocytes all played important roles in the pathogenesy of EAE.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.

Objective To explore latent class of psychological distress among the elderly with multiple chronic conditions in the community and to analyze differences in demographic and alexithymia characteristics across class.Methods A total of 685 urban and rural elderly with chronic disease co-morbidities in 6 prefecture-level cities in Jiangsu Province were selected for the study using the General Information Questionnaire,the Depression Anxiety and Stress Scales-21,and the Toronto Alexithymia scale from November 2022 to March 2023 using a convenience sampling method.Results A total of 662 older adults with multiple chronic conditions were finally investigated with a total psychological distress score 30.00(16.00,52.00).Psychological distress manifested itself in 4 different potential categories named"stress-depressive"(19.9%),"low distress"(26.0%),"stress-anxiety"(23.4%),and"overall high distress"(30.7%).The comparison of the different psychological distress categories with respect to age group,marital status,residential status,financial stress of illness,acute events within 1 year,and self-perceived health status showed statistically significant differences(P＜0.05).The comparison of alexithymia scores for the 4 potential categories showed statistically significant differences(F=136.544,P＜0.001).Conclusion Psychological distress in older adults with multiple chronic diseases has distinct categorical features,and alexithymia varies across different categories of psychological distress.Healthcare professionals can adopt targeted interventions according to different categories of chronic disease co-morbidities in order to reduce their psychological distress,and at the same time they should focus on older adults with the alexithymia of"stress-depressive"and"overall high distress".

OBJECTIVETo investigate the anti atherosclerosis effect and related mechanisms of total flavone of radix puerariae (TFRP) on atherosclerotic plaques in apoE gene deficiency (apoE-/-) mice.

METHODSapoE-/- mice were treated with saline, TFRP 15 mg . kg(-1). d(-1) or TFRP 85 mg . kg-1. d-1 (n = 8 each group) respectively per gavage for 12 weeks. The apoptotic cells in atherosclerotic plaques were then detected by TUNEL analysis, transmission electron microscope (TEM). The expression of CD-68, SMA and Caspase-3 were determined by immunochemical methods.

RESULTSEarly macrophage apoptosis signs were observed under TEM, TUNEL-positive and CD-68 positive cells were found in lipid cores of atherosclerotic plaques. TFRP significantly reduced the number of apoptotic cells in a dose-dependent manner [(0.38 +/- 0.17)%, (1.95 +/- 1.02)%, (10.50 +/- 5.89)%, respectively, P < 0.01] in atherosclerotic plaques. TFRP treatment also significantly reduced the immune expression of Caspase-3 protein in a dose-dependent manner.

CONCLUSIONTFRP significantly attenuated the development of advanced atherosclerotic plaques in a dose-dependent manner which might related to down-regulated expression of Caspase-3 protein and reduced macrophage apoptotic cells in atherosclerotic plaques post TFRP treatment.

OBJECTIVETo detect sperm mitochondrial membrane potential (MMP) of varicocele patients and investigate its clinical significance.

METHODSSixty-seven varicocele patients were divided into a VC1 (grade 1, n = 26), a VC2 (grade 2, n = 21) and a VC3 group (grade 3, n = 20). And 29 normal fertile volunteers were included in a control group ( m = 29). Conventional semen analyses were performed by computer-assisted semen analysis (CASA). Semen samples were washed, followed by JC-1 staining to evaluate the sperm MMP (JC-1+ %) by flow cytometry.

RESULTSThe sperm MMPs of the VC1, VC2 and VC3 groups were siginificantly lower ([56.29 +/- 16.32]%, P < 0.05; [45.04 +/- 13.21]%, P < 0.01; [31.63 +/- 12.91]%, P < 0.01) than that of the control ([76.21 +/- 13. 96]%). There was a significant positive correlation between the percentage of JC-1+ and that of grade (a + b) sperm (r =0.693, P=0.000).

CONCLUSIONThe decreased MMP in the sperm of varicocele men might be one of the important causes of male infertility.

Objective To investigate the effectiveness and cost of 50% and 80% wettable powder of niclosamide ethanolamine salt (NESWP) and 26% metaldehyde and niclosamide suspension concentrate (MNSC) in hilly schistosomiasis-endemic regions, so as to provide insights into the selection of chemical molluscicides in hilly regions. Methods In September 2020, a wasteland in Guanshanqiao Village, Yanrui Township, Yushan County of Jiangxi Province was selected as the experimental region, which was sectioned into five blocks and defined as four experimental groups (A₁, A₂, B, C) and a blank control group (D). 80% NESWP were given at doses of 1 g/m² and 1.5 g/m² in groups A₁ and A₂ using the spraying method, 50% NESWP was given at a dose of 2 g/m² in Group B using the spraying method, and 26% MNSC was at a dose of 4 g/m² in Group C using the spraying method, while no chemical treatment was given in Group D. Snail survey was performed using a systematic sampling method before chemical treatment and 1, 3, 7 d and 15 d post-treatment to examine the molluscicidal effect, and all molluscicidal costs were estimated to calculate the cost of chemical treatment per 1 m² and the cost of the reduction in the mean density of living snails per 1%. Results The highest mortality of snails was 78.95% and the lowest density of living snails was 0.2388 snails/0.1 m² in the experimental groups within 7 d of chemical treatment, and the highest mortality of snails was 94.74% and the lowest density of living snails was 0.058 0 snails/0.1 m² 7 d post-treatment. There were no significant differences in the snail mortality among the A₁, A₂, B and C groups 1 (χ² = 2.250, P > 0.05), 3 (χ² = 1.779, P > 0.05) or 15 d post-treatment (χ² = 2.286, P > 0.05), while a significant difference was detected in the snail mortality among the four groups 7 d post-treatment (χ² = 7.990, P = 0.046). In addition, there were no significant differences in the snail mortality between A₁ and A₂ groups 1 (χ² = 0.724, P > 0.05), 3 (χ² = 0.584, P > 0.05), 7 (χ² = 0.400, P > 0.05) or 15 d post-treatment (χ² = 0.251, P > 0.05). The costs of chemical treatment per 1 m² were 0.58, 0.60, 0.64 Yuan and 0.73 Yuan in groups A₁, A₂, B and C, and the costs of the mean density of living snail per 1% reduction were 19.29, 20.44, 21.68 Yuan and 23.53 Yuan in groups A₁, A₂, B and C, respectively. Conclusion 80% NESWP shows a high molluscicidal efficacy and low cost in hilly schistosomiasis-endemic regions.

ObjectiveTo study the correlation of high-risk human papillomavirus 16 and 18 (HPV16/18) infections with the risk of prostate cancer (PCa) and their association with the clinicopathologic indexes of PCa.

METHODSWe collected tissue samples from 75 cases of PCa and 73 cases of benign prostatic hyperplasia (BPH). We detected HPV16/18 infections in the samples by immunohistochemistry and PCR combined with reverse dot blot (RDB) assay.

RESULTSImmunohistochemistry revealed 16 cases of HPV16/18 positive in the PCa (21.3%) and 7 cases in the BPH samples (9.5%), with statistically significant difference between the two groups (P=0.049). PCR combined with RDB assay showed 17 cases of HPV16 infection (22.6%) and 13 cases of HPV18 infection (17.8%), including 4 cases of HPV16/18 positive, in the PCa group, remarkably higher than 6 cases of HPV16 infection (8.2%), 3 cases of HPV18 infection (4.1%) and no HPV16/18 positive in the BPH controls (P=0.001). No significant differences were observed between the result of immunohistochemistry and that of PCR combined with RDB assay (P=0.069). The risk of HPV16/18 infections was found to be correlated with the clinical T-stage and Gleason score of PCa (P<0.05 ) but not with the patient's age, PSA level or lymph node metastasis (P>0.05 ).

CONCLUSIONSHigh-risk HPV16/18 infections are correlated with the risk of prostate cancer.
