The organisms in pathologic tissues of sporotrichosis were detected by ABC technique. Brown spores were found, some spores appeared to be round, or pearshaped,budding spores or asteriod hotlies were observed, and some spores were phagocytlzed by leukocytes and macrophages. The diameter of spores ranged from 2. spin to 10. 0um. The sensitivity of this method is 96. 2% and the specificity 100%. Examining one case takes about three hours. The method can be used for retrospective study, as well as rapid diagnosis of sporotrichosis.

During 2004 to 2009, 701 patients with diabetes were under community-hospital-based integrated management at Zhonghua and Xiagang community health-care service centers, Xiamen, Fujian.Changes of clinical indicators, life-style and frequency of checks for its complications in them were compared before and after the management. All clinical indicators decreased with length of management, with fasting blood glucose from ( 7. 6 ± 2. 3 ) mmol/L before management to ( 7. 3 ± 2. 0) mmol/L half a year after management, (7. 2 ± 2. 1 ) mmol/L one year after management, (6. 9 ± 1.7 ) mmol/L two years after management. Their life-style also improved significantly and frequency of checks for complications increased with: 54. 4% for retinopathy, 52. 5% for diabetic foot, and 51.8% for neuropathy after management (P ＜0. 05).

Objective To investigate the effect of potassium iodide on the incidence of sporotrichosis, and provide the theoretical basis for the prevention of sporotrichosis. Methods Experimental mice were divided into 4 groups, group 1～3 were fed with water containing different doses of potassium iodide, and no potassium iodide was given to the control group. After two weeks, the fungi were inoculated intraperitoneally to all the mice. In the third to the eighth weeks, the mice were sacrificed every week in batches. The infection, pathological changes and mycological findings of the mice were observed. Results The incidence rate of experimental sporotrichosis was significantly decreased in the mice (P

Objective To investigate the role of insulin resistance in the pathogenesis of childhood benign acanthosis nigricans with obesity and the relationship between insulin resistance and insulin receptors.Methods Fasting plasma insulin and the amount of erythrocyte insulin receptors were determined among17children with benign acanthosis nigricans with obesity(CBANO),with16cases of simple adiposis and15healthy children as controls.Results The levels of plasma insulin were higher in CBANO than those in sim-ple adiposis and healthy controls;however,the amount of erythrocyte insulin receptors was lower in CBANO than that in simple adiposis and healthy controls.Conclusion Insulin resistance caused by diminished in-sulin receptors may play an important role in pathogenesis of CBANO.

Objective: This study aims to explore the relationships of family functioning, general well-being, and exercise with psychological distress.Furthermore, we investigated the special roles of general well-being and exercise on the association between family functioningand psychological distress. Methods: Of 769 end-stage renal disease (ESRD) patients participated in the cross-sectional study which consisted of the 12-item GeneralHealth Questionnaire (GHQ-12), the Family APGAR Scales, and the General Well-Being Schedule. The collected data were analyzedusing multiple linear regression analysis and path analysis. Results: The prevalence of psychological distress was 72.3%. Family functioning, general well-being and exercise were associated factorsof psychological distress (p<0.05). The indirect effect of family functioning on psychological distress was partially mediated by generalwell-being (Effect=-0.08, 95% CI=-0.11, -0.04). In addition, the effect of family functioning on general well-being was moderated byexercise (Index=-0.092, SE=0.033, 95% CI=-0.159, -0.029). Conclusion The prevalence of psychological distress among ESRD patients was high. Family functioning, general well-being and exercisewere associated with psychological distress. Family functioning could affect psychological distress partially by affecting general wellbeing.Furthermore, exercise had a significant moderating effect on the relationship between family functioning and general well-being.Psychiatry Investig 2020;17(4):356-365

Objective To evaluate the therapeutic effects of stem cell transplantation in heart failure patients with old myocardial infarction (OMI) by MRI.nethods Hcart failure patients [NYHA 2.7±0.7,male=18,mean age (59.5±10.1) Y] with OMI were randomly divided into 2 groups (group A:CABG+stem cell transplantation,group B:CABG;n=10 each).Left ventricular (LV) function was measured by MRI,viable myoeardium was detected by 18F-FDG myocardial metabolism imaging and late contrast-enhanced at baseline and 6 months post intervention.Results LVEF and LVEDV at baseline for group A were (20.71±6.09)% and (172.73±32.74) ml,and for group B were (27.59±2.31)% and (155.13±28.36)ml,respectively (P＞0.05).The LVEF was equally improved in group A and B (mean 8.63% vs.10.37%,P＞0.05) while ALVEDV was significant higher in group A than that in group B [(9.91±39.50)ml vs.(-22.34±31.35)ml.P＜0.05].Ventricular wall thickening ratio at 6 months post intervention was significantly higher in group A than that in group B[(11.40 ±11.53)% vs.(2.27±7.20)%,P＜0.05].Late contrast-enhanced M RI results correlated with 18F-FDG myocardial metabolism imaging SPECT well in assessment of myocardial viability (kappa value:0.446,P＜0.001;sensitivity:68.3% and specificity:92.5%).Conclusions Stem cell therapy on top of CABG aggravated LV remodeling in heart failure patients with old myocardial infarction.The specificity of MRI Is similar to 18F-FDG SPECT while the sensitivity is inferior to 18F-FDG SPECT on detecting viable myocardium.

Objective:To compare the incidence of coronary microvascular disease (CMVD) between patients with non-obstructive and obstructive coronary arteries.Methods:We retrospectively analyzed 97 patients with angina pectoris, who underwent the absolute quantitative PET examination of myocardial perfusion and coronary anatomy examination within 90 days. All patients were divided into two groups: non-obstructive group (72 cases, no stenosis ≥50% in all three coronary arteries) and obstructive group (25 cases, at least one coronary stenosis ≥50%; and at least one coronary stenosis<50%). Quantitative parameters derived from PET including rest myocardial blood flow (RMBF), stress myocardial blood flow (SMBF), coronary flow reserve (CFR) and cardiovascular risk factors were compared between the two groups. CMVD was defined as CFR<2.90 and SMBF <2.17 ml·min -1·g -1. Results:Incidence of CMVD was significant higher in the non-obstructive coronary arteries of the obstructive group than in the non-obstructive coronary arteries of non-obstructive group (47.1% (16/34) vs. 25.5% (55/216), χ 2=6.738, P=0.009) while incidence of CMVD was similar between non-obstructive and obstructive patients ((44% (11/25) vs. 33.3% (24/72), χ 2=0.915, P=0.339). RMBF ((0.83±0.14) ml·min -1·g -1 vs. (0.82±0.17) ml·min -1·g -1), SMBF ((2.13±0.60) ml·min -1·g -1 vs. (1.91±0.50) ml·min -1·g -1) and CFR (2.59±0.66 vs. 2.36±0.47) were similar between the two groups (all P>0.05). Conclusions:CMVD can occur in non-obstructive coronary arteries in both patients with non-occlusive coronary arteries and patients with obstructive coronary arteries. Prevalence of CMVD is significantly higher in patients with obstructive coronary arteries than in patients with non-obstructive coronary arteries. The CMVD severity is similar between the two groups.

BACKGROUND: Limited published research has examined the relationships of negative life events and coping styles with sleep quality in Chinese junior high school students. We aimed to investigate the prevalence of poor sleep quality and to clarify the role of coping styles between negative life events and sleep quality. METHODS: A cross-sectional study of 3081 students was conducted in Ganzhou City, Jiangxi Province, Southeastern China. Adolescent Self-Rating Life Events Checklist, Simplified Coping Style Questionnaire, and Pittsburg Sleep Quality Index were applied to assess negative life events, coping styles, and sleep quality, respectively. Descriptive analyses, independent-samples t tests, one-way analyses of variance, Pearson correlation analyses, and structural equation modeling (SEM) were applied to analyze the data. RESULTS: The prevalence of poor sleep quality was 26.7%. Negative life events (B = 0.038, P < 0.001) and negative coping style (B = 0.049, P < 0.001) demonstrated a positive association with poor sleep quality, while positive coping style indicated a negative association with poor sleep quality (B = -0.029, P < 0.001). Interactions of negative life events and coping styles with sleep quality were not found (all P > 0.05). The association between negative life events and sleep quality was mediated by negative coping styles. CONCLUSIONS Our results indicated that poor sleep quality was common in these Chinese adolescents. Negative life events and negative coping style were associated with an increased prevalence of poor sleep quality, while the positive coping style was related to a decreased prevalence of poor sleep quality. A negative coping style mediated the association between negative life events and sleep quality.

BACKGROUND: Most Chinese migrants have been faced with obstacles to getting access to local public health services. Young migrants among internal migrants make a major contribution to the economy. However, the establishment of their health records has been ignored. This research was aimed at exploring the status and associated factors of the establishment of health records among young Chinese migrants. METHODS: Data were obtained from the 2017 China Migrants Dynamic Survey (CMDS). Chi-square test and binary logistic regression were performed to investigate the associated factors of the establishment of health records among young Chinese migrants. RESULTS: Approximately 30.2% of young migrants had their health records established in inflow communities. Urban residence, medical insurance (insured), and lower average monthly household income were attributed to the establishment of more health records. Young migrants who were in northeast China and across provinces and immigrated for working or engaging in trade were less likely to have health records established. Young migrants who participated in social activities and public affairs activities and took type of people in touch as natives in the inflow area showed a higher possibility of establishing health records. Meanwhile, receiving health education and hearing about national basic public health services (BPHSs) were beneficial for establishing the health records of more young migrants. CONCLUSION This study showed that the health records of young migrants had a relatively low establishment rate. Sociodemographic and migration characteristics, health status, public health services, and social integration factors were all related to the health record establishment of young Chinese migrants.
