Objective To investigate whether intrauterine hypoxia and ischemia can produce long-time effects or NOSI can prevent these damages. Methods Fetal rat intrauterine distress model was constructed. The rats were divided into the normal group, hypoxia and ischemia reperfnsion group and treatment group. Pupa were given to surrogate mothers and the ability of learning and memory at 40 day of age after delivery were examined. Then the water maze test was performed to detect the space learning ability and memory function of rats, and the changing of synaptophysin levels in hippocampns were detected by immunohistochemical staining. Result Behavioral results show that fetal distress produces cognitive impairment demonstrated by Morris water maze performance including a higher escape latency score and a de-creased cross platform time. The COD of Syp positive immunoreactive product in hippocampus were less decreased than that in the normal group or NOSI group. But the behavioral results and the COD of synaptophysin had no difference between normal group and NOSI group. Conclusions Fetal distress produced cognitive impairment and led to the decreasing of synaptophysin in hippocampns. Effective measure can relieve these damages.

Objective To compare the curative efficacy and safety of subcutaneous immunotherapy (SCIT) versus sublingual immunotherapy (SLIT) for allergic rhinitis.Methods A total of 127 cases of patients with allergic rhinitis in the outpatient department of our hospital from June 2009 to March 2016 were retrospectively analyzed,including 79 cases treated with SCIT and 48 cases treated with SLIT.The curative effects and adverse reactions were compared between the two groups.Results After 3-year treatment,the total effective rate in the SCIT group was 75.9%,which was higher than 72.9% in the SLIT group,but the difference was not statistically significant (χ2=0.15,P>0.05).The incidence rate of adverse reactions in the SCIT group was 26.6%,which was higher than 10.4% in the SLIT group,the difference between the two groups was statistically significant (χ2=4.79,P<0.05).Conclusion The two desensitization treatment methods all gain better effect,but SLIT has lower occurrence rate of adverse reactions.

Objective : To investigate the trends in incidence of malignant tumors in Yongkang City, Zhejiang Province from 2013 to 2019, so as to provide insights into formulation of the malignant tumor control strategy. Methods: Data pertaining to the incidence of malignant tumors from 2013 to 2019 were captured from the Zhejiang Chronic Disease Monitoring Information System. Based on the International Classification of Diseases 10th Revision (ICD-10) and data from the national population census, the constituent ratio, crude incidence and Chinese population-standardized incidence of malignant tumors were estimated, and the trends in incidence of malignant tumors were investigated using annual percent change (APC). Results: The annual mean crude incidence and Chinese population-standardized incidence of malignant tumors were 356.75/105 and 226.97/105, which both appeared an overall tendency towards a rise (APC=5.887% and 4.815%, both P<0.05). The crude incidence of malignant tumors appeared a tendency towards a rise among both men (APC=3.860%, P<0.05) and women (APC=8.534%, P<0.05) from 2013 to 2019, and the Chinese population-standardized incidence of malignant tumors appeared a tendency towards a rise among women (APC=8.392%, P<0.05). The largest increase in the crude incidence of malignant tumors was seen among women at ages of 15 to 44 years (APC=11.599%, P<0.05). In addition, the Chinese population-standardized incidence of lung cancer, colorectal cancer and thyroid cancer all showed a tendency towards a rise among men (all P<0.05), and the Chinese population-standardized incidence of lung cancer and thyroid cancer both appeared a tendency towards a rise among women (both P<0.05). Conclusions The incidence of malignant tumors showed a tendency towards a rise in Yongkang City from 2013 to 2019, and the elderly and young females are high-risk populations for malignant tumors. Lung cancer, thyroid cancer and colorectal cancer are cancers that should be given a high priority.

OBJECTIVE: To investigate the clinical characteristics of ocular symptoms in patients with allergic rhinitis (AR) and the impact of the ocular symptoms on patients' quality of life. METHOD: AR patients' history and clinical data were collected and analyzed. One hundred cases were extracted from adult patients with and without ocular symptoms in each group and their quality of life were evaluated using rhino-conjunctivitis quality of life questionnaire (RQLQ). RESULT: Totally 1119 cases were collected and 859 cases had ocular symptoms. Of the patients with ocular symptoms, 582 cases were mild, 234 cases were moderate, 43 cases were severe. Eye itching was the most common symptom, followed by tears, hyperemia and swelling. Patients with ocular symptoms had longer disease history than non ocular symptom group (P < 0.05). There was a positive correlation between ocular and nasal symptoms (P < 0.01); patients with ocular symptoms had more severe nasal symptoms than patients without ocular problems; while patients with moderate to severe AR had more severe ocular symptoms than mild AR patients (P < 0.01). Female patients had higher incidence (P < 0.05) and ocular symptoms score (P < 0.05) than male. Children less than 10 years old had a relative lower incidence and score of ocular symptoms. While the incidence and score had an increasing trend for patients older than fifty. There was no difference regarding the type and number of allergen in the patients with and without ocular symptom. Moreover, patients with ocular symptoms had higher scores in the domains of non-nose/eye symptoms, practical problems, ocular symptoms, emotional function and total score in RQLQ than patients without ocular symptom. CONCLUSION It was common for the AR patients to have ocular symptoms, and ocular symptoms had obvious influence on the patients' quality of life. So controlling of the ocular symptoms should not be ignored during the diagnosis and treatment of AR.

Purpose: Cerebral ischemia-reperfusion (IR) injury is a severe secondary injury induced by reperfusion after stroke. Didymin has been reported to have a protective effect on intracerebral hemorrhage. However, the underlying mechanism of didymin on regulating cerebral IR injury remains largely unknown. Materials and Methods: A rat cerebral IR model and oxygen-glucose deprivation/reperfusion (OGD/R) model in PC12 cells were established. Hematoxylin and eosin (H&E) was used to detect the pathological changes in brain tissues, and TUNEL staining was performed to detect apoptosis of brain tissues. MTT and flow cytometry were used to measure the viability and apoptosis of PC12 cells. QRT-PCR and western blot were used to detect inflammation cytokines in PC12 cells. Western blot was used to measure the expression of PPAR-γ, RXRA, Bax, c-caspase-3, and Bcl-2. Results: Didymin pretreatment decreased apoptotic rates, reduced levels of Bax and c-caspase-3, and increased Bcl-2 level in vivo and in vitro. Additionally, didymin pretreatment increased viability and decreased the inflammation levels [interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and monocyte chemotactic protein (MCP)-1] of OGD/R treated PC12 cells. Moreover, didymin activated the peroxisome proliferator-activated receptors (PPAR) signaling pathway and increased the expression of PPAR-γ and RXRA in OGD/R treated PC12 cells. Inhibition of PPAR-γ eliminated the protective effect of didymin on OGD/R treated cells. Conclusion Didymin protected neuron cells against IR injury in vitro and in vivo by activation of the PPAR pathway. Didymin may be a candidate drug for IR treatment.

Objective:To investigate the molecular mechanism of excessive iodine induced experimental autoimmune thyroiditis (EAT) in mice.Methods:Sixty female non-obese diabetic (NOD) mice were selected and divided into 5 groups according to body weight [(25 ± 3) g] via the random number table method, with 12 mice in each group: control group (group A), 10-fold high iodine group (group B), 100-fold high iodine group (group C), 1 000-fold high iodine group (group D) and 1 000-fold high iodine combined with polyinosinic acid-polycytidylic acid [Poly (I:C)] group (group E). The experiment period was 16 weeks. Mice in each group drank purified water with sodium iodine (NaI) content of 0.000, 0.005, 0.050, 0.500 and 0.500 mg/L, respectively; mice in group E were intraperitoneally injected with Poly (I:C) at week 7 and week 15, respectively. At the end of the 16th week, mice were dissected and blood samples and thyroid tissue were taken. The levels of serum thyroid function indexes [thyroid stimulating hormone (TSH), free triiodothyronine (FT 3), free thyroxine (FT 4), and thyroid peroxidase antibody (TPOAb)] were detected by enzyme-linked immunosorbent assay (ELISA); the pathological changes of thyroid tissue were observed after hematoxylin-eosin (HE) staining; differentially expressed genes in thyroid tissue were detected by RNA-sequencing (RNA-seq), and analyzed by KEGG pathway; mRNA and protein levels of p38, intercellular adhesion molecule-1 (ICAM-1) and chemokine 10 (CXCL10) in thyroid tissue were detected by real-time fluorescence quantitative PCR (qPCR) and Western blotting, respectively. Results:There were statistically significant differences in serum levels of TSH (ng/ml: 6.53 ± 0.86, 6.61 ± 0.82, 7.68 ± 0.55, 7.93 ± 0.60, 8.73 ± 1.60), FT 3 (pg/ml: 59.35 ± 10.16, 53.73 ± 10.96, 46.19 ± 8.03, 41.01 ± 8.67, 34.21 ± 11.75), FT 4 (pg/ml: 136.74 ± 10.06, 124.33 ± 14.34, 101.80 ± 6.78, 91.37 ± 6.75, 73.29 ± 17.31), and TPOAb (U/ml: 130.81 ± 24.53, 145.47 ± 28.89, 166.52 ± 41.59, 199.78 ± 42.19, 201.99 ± 44.03) among the 5 groups of mice ( F = 4.77, 4.96, 23.12, 3.68, P < 0.05). Compared with group A, the serum TSH levels of mice in groups C, D and E were higher, the levels of FT 3 and FT 4 in groups B, C, D and E were lower, and the levels of TPOAb in groups D and E were higher, and the differences were statistically significant ( P < 0.05). HE staining showed that the thyroid follicle lesion in groups D and E was serious, and the EAT phenotype appeared in both groups. The differentially expressed genes were analyzed by KEGG pathway. Compared with group A, 8 metabolic pathways related to thyroid autoimmunity and inflammation were found in groups B, C, D and E. Further analysis found that 3 genes appeared in multiple pathways, namely p38, ICAM-1 and CXCL10. There were significant differences in the mRNA levels of p38, ICAM-1 and CXCL10 in thyroid tissue of the 5 groups of mice ( F = 14.77, 12.76, 16.39, P < 0.05); compared with group A, the mRNA levels of p38 in groups B, C, D and E were higher, and the mRNA levels of ICAM-1 and CXCL10 in groups C, D and E were higher ( P < 0.05). There were significant differences in the protein levels of p38, ICAM-1 and CXCL10 in thyroid tissue of the 5 groups of mice ( F = 7.97, 73.86, 18.02, P < 0.05); compared with group A, the protein levels of ICAM-1 and CXCL10 in groups B, C, D and E were higher ( P < 0.05). Conclusion:Excessive iodine promotes the occurrence and development of EAT in mice by up-regulating the expressions of p38 and ICAM-1 genes that are closely related to thyroid autoimmune and inflammatory responses.
