Objective:To explore the correlation between serum levels of interleukin-9 (IL-9), platelet activating factor (PAF), total immunoglobulin E (IgE), interferon γ (IFN-γ), and interleukin-4 (IL-4) in patients with chronic spontaneous urticaria (CSU).Methods:Sixty CSU active phase patients admitted to the First Affiliated Hospital of Hebei North University from March 2018 to March 2019 were selected and included in the CSU active phase group. Based on the 7-day Urticaria Activity Score (UAS7), they were divided into three groups: 15 mild group, 25 moderate group, and 20 severe group; And 19 patients who entered the quiescent phase of the disease after 28 days of standardized antihistamine treatment were included in the CSU quiescent phase group. Another 30 healthy subjects who participated in the physical examination at the same time at our hospital′s physical examination center were selected to be included in the healthy control group. 5 ml of fasting elbow vein blood was collected from CSU active and stationary patients, as well as healthy subjects. The serum levels of IL-9, PAF, total IgE, IFN-γ, and IL-4 were detected using enzyme-linked immunosorbent assay. Pearson correlation test was used to analyze the correlation between serum IL-9, PAF levels and total IgE, IFN-γ, and IL-4 levels in CSU active patients.Results:The serum levels of IL-9, PAF, total IgE, and IL-4 in the CSU active phase group were higher than those in the CSU stationary phase group and healthy control group (all P<0.05), and the serum IFN-γ levels were lower than those in the CSU stationary phase group and healthy control group (all P<0.05). There was no statistically significant difference in the levels of the above indicators between the healthy control group and the CSU stationary group (all P>0.05). The serum levels of IL-9, PAF, total IgE, and IL-4 in the severe group were significantly higher than those in the mild and moderate groups (all P<0.05), and the serum IFN-γ levels were significantly lower than those in the mild and moderate groups (all P<0.05); The serum levels of IL-9, PAF, total IgE, and IL-4 in the moderate group were significantly higher than those in the mild group (all P<0.05), and the serum IFN-γ levels were significantly lower than those in the mild group ( P<0.05). Pearson correlation analysis showed that serum IL-9 and PAF levels were positively correlated with serum total IgE and IL-4 levels in CSU active phase patients (IL-9: r=0.726, 0.870, PAF: r=0.788, 0.795, all P<0.01), and negatively correlated with serum IFN-γ levels (IL-9: r=-0.831, PAF: r=-0.816, all P<0.01). Conclusions:The serum levels of IL-9 and PAF in patients with active CSU are elevated and correlated with total IgE, IFN-γ, and IL-4 levels, suggesting that IL-9 and PAF may be related to the occurrence and development of CSU.

Objective:To evaluate the effectiveness of prevention and control of coal-burning-borne endemic fluorosis in Sichuan Province, and to provide basis for further development of targeted prevention and control measures.Methods:According to the requirements of the Implementation Plan for the Elimination and Evaluation of Coal-burning-borne Endemic Fluorosis in Sichuan Province, from 2018 to 2021, the assessment of the elimination of coal-burning-borne endemic fluorosis was carried out in all the endemic fluorosis villages of 23 counties (cities, districts) in Sichuan Province. In each village, 30 households were selected to be investigated the use of improved stoves, the drying of corn and pepper for human consumption, and the prevalence of dental fluorosis among all children aged 8 - 12 years old in the village.Results:A total of 222 242 households were surveyed in 1 640 villages, 196 towns, 23 counties (cities, districts) in Sichuan Province. Among them, the rate of qualified improved stoves was 99.99% (222 238/222 242), the correct use rate of qualified improved stoves was 99.90% (212 026/222 238), and the correct drying rate of corn and pepper for human consumption was 99.96% (212 630/212 721). A total of 135 125 children aged 8 to 12 years old were examined, and 5 927 cases of dental fluorosis were detected. The prevalence of dental fluorosis in children was 4.39%. The grading of dental fluorosis was mainly very mild and mild, which were 2.71% (3 656/135 125) and 1.32% (1 783/135 125), respectively. In the county-level self-assessment of 1 640 villages, 1 621 villages had reached the elimination standard, with the elimination rate of 98.84%. Taking counties as a unit, the elimination rate of diseased villages ranged from 96.69% to 100.00%, and 23 diseased counties (cities, districts) had reached the elimination standard. In the provincial-level review results of 174 villages with endemic fluorosis, 174 diseased villages had reached the elimination standard, with the consistency rate of 98.85% (172/174) with the county-level self-assessment results. Among them, except for Gulin County, the consistency rate of self-assessment results was 7/9, the consistency rate of other counties (cities, districts) was 100.00%.Conclusions:The prevention and control of coal-burning-borne endemic fluorosis in Sichuan Province has achieved remarkable results, and all the diseased counties (cities, districts) have reached the elimination standard. In the future, we should continue to take active prevention and control measures to ensure that the elimination status is maintained.

Objective:To explore the relationship of serum interleukin (IL) -9 and platelet-activating factor (PAF) levels with serum total immunoglobulin E (IgE) levels, disease severity and disease course in patients with chronic spontaneous urticaria (CSU) .Methods:A total of 60 patients with active CSU were collected from Department of Dermatology, the First Affiliated Hospital of Hebei North University from March 2018 to March 2019 (active CSU group), and divided into mild group, moderate group and severe group according to 7-day urticaria activity score (UAS7). After 28-day standard antihistamine therapy, the patients whose condition became stable were included in the stable CSU group. During the same period, 30 health examinees were included in the healthy control group. Peripheral venous blood samples were collected from the subjects in each group, enzyme-linked immunosorbent assay (ELISA) was performed to detect serum levels of IL-9 and PAF, and immunoturbidimetric assay to detect the serum total IgE level. Correlations of serum IL-9 and PAF levels with serum total IgE levels, UAS7 scores and disease courses were analyzed in patients with CSU. One-way analysis of variance was used for comparisons among multiple groups, least significant difference- t test for multiple comparisons, and Pearson correlation analysis for correlation analysis. Results:Totally, 28 males and 32 females were included in the active CSU group, their age ranged from 11 to 68 years (34.68 ± 8.62 years), and the disease duration ranged from 2 months to 7 years (1.42 ± 0.41 years). In the healthy control group, 14 were males and 16 were females, and their age ranged from 10 to 70 years (35.06 ± 7.89 years). According to UAS7, 12, 26, and 22 patients were diagnosed with mild, moderate and severe CSU respectively, and 22 were included in the stable CSU group after standard treatment. The levels of serum IL-9, PAF and total IgE significantly differed among the active CSU group, stable CSU group and healthy control group (IL-9: 144.34 ± 23.19 vs. 109.25 ± 20.77 vs. 107.23 ± 19.23 pg/ml; PAF: 362.45 ± 51.45 vs. 223.18 ± 32.46 vs. 221.23 ± 28.38 pg/ml; total IgE: 168.12 ± 32.48 vs. 24.04 ± 7.04 vs. 21.76 ± 5.95 IU/ml; F = 38.80, 148.38, 499.12, respectively, all P < 0.001), and were significantly higher in the active CSU group than in the stable CSU group and healthy control group (all P < 0.05), while there was no significant difference between the stable CSU group and healthy control group (all P > 0.05). Pearson correlation analysis showed that the serum IL-9 and PAF levels were positively correlated with serum total IgE levels and UAS7 scores (all P < 0.05), but not correlated with the disease course (both P > 0.05) . Conclusion:Serum IL-9 and PAF levels in patients with active CSU were markedly elevated along with the increase in disease severity, and closely correlated with serum total IgE levels.

Prognostic value of thromboelastography maximum amplitude and arterial blood lactate levels for sepsis in elderly patients / 中华老年医学杂志

Objective:To evaluate the prognostic value of thromboelastography maximum amplitude(MA)and arterial blood lactate levels for sepsis in elderly patients.Methods:A retrospective analysis was performed on clinical data of 63 sepsis patients(≥60 years old)admitted to the Intensive Care Unit(ICU)of Bethune Hospital of Shanxi Province from December 2018 to February 2020.MA values, white blood cell counts, lymphocyte counts, platelets, acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)scores, sequential organ failure assessment(SOFA)scores, underlying diseases, body mass index, laboratory test results and other related treatments were analyzed.The subjects were divided into the survival group and the death group according to the 28-day survival outcome.Differences in MA, APACHE Ⅱ scores, SOFA scores and laboratory test results between the two groups were analyzed, and the correlations of MA with infection parameters and age were examined.Influencing factors of survival outcomes were analyzed using multivariate Logistic regression.The receiver operating characteristic curve(ROC)was used to calculate the prognostic value of MA and arterial lactate for sepsis in elderly patients.Results:The main sources of infections were pulmonary and abdominal(79.4%, 50/63)in 63 elderly patients with sepsis.The incidences of positive blood cultures and deaths were 15.9%(10/63)and 66.7%(42/63), respectively.There existed significant differences in lymphocyte counts, arterial lactate levels, MA and lengths of stay in the ICU between the survival group and the death group( t=3.847, 2.153, 2.745, -3.574, respectively, all P<0.05).MA was correlated with arterial lactate, SOFA score and survival outcome( r=-0.498, -0.506, and -0.358, respectively, all P<0.05).Multivariate Logistic regression analysis showed that MA and arterial lactate were independent factors for the survival outcome( OR=1.626, 0.766, all P<0.05).The area under the ROC curve(AUC, 95% CI)for the combination of MA and arterial lactate was larger than that of either MA or arterial lactate alone(0.89, range: 0.763-0.846; 0.58, range: 0.574-0.730; 0.77, range: 0.521-0.832; all P<0.05). Conclusions:The combination of thromboelastography maximum amplitude and lactate in arterial blood has important clinical value in assessing the prognosis of elderly patients with sepsis.

The control group was treated with laparoscopic surgery, the observation group was treated with leuprorelin treatment, and the levels of FSH, E2, luteinizing hormone and PROG were tested by automatic biochemical analyzer between two groups before and after treatment, the pregnancy rate as assessment of reproductive function in patients. Clinical curative effect and effect on fertility of 2 groups were compared. Results Levels of FSH, E2, LH and PROG in the observation group were lower than those in the control group (P<0.05) in 3 months after treatment, and the pregnancy rates in the observation group after 1 months, 2 months and 3 months were higher than that in the control group (P<0.05). Conclusion The treatment of Laparoscopy combined with Leuprolide for mild endometriosis and infertility in patients has ideal effect, and is worthy of popularization and application.

Protective effects of crocin in oxidative stress cell model and the effect on PI3K/Akt signal pathway / 中华行为医学与脑科学杂志

Objective To investigate the protective effect of crocin on oxidative stress cell model of PC 12 cell and the effect of crocin on PI3K/Akt signal pathway,as well as further explore the mechanism of protective effect on model cells.Methods Cells were divided into control group,model group,crocin group and VE group.The cell survival rate was detected by MTT method,and the expression of mRNA and protein of PI3K/Akt were detected by RT-PCR and Western blot.Results With the crocin concentration in 0.625 μM and 5 μM,the cell survival rate increased in a dose-dependent manner.The average optical density rate of PI3K and Akt mRNA were 0.435±0.044 and 0.375 ± 0.034,and the PI3K and Akt protein were 0.378± 0.038 and 0.386± 0.043 of crocin group.Compared with the model group,the expression levels of PI3K/Akt increased in crocin group (P＜0.05).Conclusion These results indicate that the antioxidant and antiapoptosis effects of crocin are induced via increasing expression of PI3K and pAkt.

Role of eNOS/NO signaling pathway in peritubular capillary lesions in renal interstitial fibrosis and the related mechanism in mouse models of unilateral ureteral obstruction / 中国实验动物学报

Objective To investigate the role of eNOS/NO signaling pathway in peritubular capillary lesions of mouse renal interstitial fibrosis with unilateral ureteral obstruction ( UUC) and the potential mechanism .Methods Sixty-four healthy male KM mice were randomly divided into sham operated group ( n=32 ) and unilateral ureteral obstruction group (n =32).At each week, serum BUN, Scr and NO were determined and the percentages of CD 133 +/VEGFR+en-dothelial progenitor cells in peripheral blood mononuclear cells were detected by flow cytometry .Morphological changes of the renal tissue were observed using Masson staining .The expression of CD34 +cells in the renal interstitium was analyzed by immunohistochemistry to calculate the peritubular capillary density .The expressions of eNos and VEGF mRNA were de-termined by real-time PCR.Results The expression of blood NO , the percentages of endothelial progenitor cells , peritu-bular capillaries, eNOS mRNA, and VEGF mRNA in the UUO group were significantly decreased compared with those of the sham group at 2, 3, and 4 weeks (P<0.05).NO was positively correlated with peritubular capillaries (r =0.715, P<0.05), eNOS mRNA was positively correlated with peritubular capillaries (r =0.624, P<0.05), endothelial progeni-tor cells (r =0.375, P<0.05), and VEGF mRNA (r =0.351, P<0.05).Conclusions eNOS/NO signaling path-way participates in regulation of peritubular capillary lesions in renal interstitial fibrosis of UUO mice .The mechanism may be partly related to the regulation of vasomotor reflex , the expression of VEGF mRNA and mobilization of endothelial pro-genitor cells.

Practice and enlightenment of the British and French language analogy method in bilingual teaching / 中华医学教育探索杂志

The British and French language analogy method in bilingual teaching was applied to the clinical students who were learning medical French in Kunming Medical University. Based on the students' good English foundation , a series of problems were solved properly such as contradictions between the professional course and foreign language classes , unmatched textbooks and teaching con-tents, the teachers' quality by lexical analogy and textual analogy and the rational allocation of the British and French language analogy teaching content. The teaching contents and methods were also properly worked out and good results were got.

Analysis on Quality of Life and Its Influencing Factors in Patients with Chronic Gastritis / 昆明医科大学学报

Objective To analyze the status of quality of life and influencing factors in patients with chronic gastritis. Methods 124 chronic gastritis patients were measured by the Chronic Gastritis scale of Quality of Life Instruments for Chronic Disease (QLICD-CG) before and after treatments. The scores were compared by paired t-test,and the influencing factors were analyzed by independent sample t-test and One-Way ANOVA. Results There were significant differences in all domains and total scores between the before and after treatments. The quality of life of chronic gastritis patients were influenced by treatments,gender,marital status,occupation and economic conditions ( <0.05) . Conclusion While reasonable treatment is very important to improve quality of life of the chronic gastritis patients, some influencing factors should be addressed, and mental health education and psychological service should be strengthened.

Exploration of early scientific research training for students of long-term medical education during pathological teaching / 中华医学教育探索杂志

Long-term medical education program requires that the medical students should ac-quire both professional knowledge and scientific research ability. These students,with heavy task and course,have difficulty in performing the scientific research systematically. It is very important to develop the early scientific research training. Department of pathology in Central South University,took early sci-entific research activities in various forms,such as literature searching,reviews writing,research design-ing,experiment performing,lecture communicating and clinical practicing after combining the discipline characteristic and arranging the overall process. Satisfactory effects were achieved with efforts.

Language analogy teaching method by French and English comparison / 中华医学教育探索杂志

Our college has applied French-English analogy-educating method ( trilingual education )to the medicinal French bilingual-educating course by means of the interactions of different languages. As the kin relations between English and French in the axea of medicine, as well as their interactions from the origin to the modem medical applications, it can be an effective method to use analogy-educating method in the French study course in medicine, which means that the multi-lingual interactions can be used in the bilingual, even the multi-lingual educating activities of bilinguai educating process of other subjects.
