ABSTRACT
Objective:To investigate the efficacy of Guanqiao Zhengqi holistic therapy in the treatment of chronic rhinosinusitis. Methods:A total of 200 patients with chronic rhinosinusitis who received treatment in the Department of Otolaryngology, Shanxi Provincial Integrated Traditional Chinese Medicine and Western Medicine Hospital ( n = 72) and Shanxi Yishengtang Traditional Chinese Medicine Center ( n = 128) from January 2021 to January 2022 were included in this study. These patients were randomly assigned to undergo treatment either with mometasone furoate nasal spray and levocetirizine hydrochloride tablets (control group, n = 100) or Guanqiao Zhengqi holistic therapy combined with mometasone furoate nasal spray and levocetirizine hydrochloride tablets (observation group). All patients were treated for 4 weeks and followed up for 3 months. Clinical efficacy, modified Visual Analogue Scale score, Lund-Kennedy endoscopy scoring system score, and duration of glucocorticoid and anti-leukotriene use were compared between the two groups. Results:The total response rate in the observation group was significantly higher than that in the control group [92.00% (92/100) vs. 73.00% (73/100), χ2 = 18.45, P < 0.001). There was no significant difference in the modified Visual Analogue Scale score between the two groups before treatment ( Z = 1.37, P = 0.170). There was a significant difference in the modified Visual Analogue Scale score between the two groups after treatment ( Z = -5.27, P < 0.001). Before treatment, there was no significant difference in the Lund-Kennedy endoscopy scoring system score between the two groups ( Z = -1.65, P = 0.098) and the Lund-Kennedy endoscopy scoring system score differed significantly between the two groups after treatment ( Z = -6.03, P < 0.001). The duration of glucocorticoid and anti-leukotriene use in the observation group was significantly shorter than that in the control group [10.00 (10.00, 14.00) days vs. 42.00 (28.00, 70.00) days, 7.00 (7.00, 7.00) days vs. 21.00 (14.00, 26.25) days, Z = -11.27, P < 0.001, Z = -12.31, P < 0.001). Conclusion:Based on the conventional treatment with western medicine, Guanqiao Zhengqi holistic therapy for the treatment of chronic rhinosinusitis can effectively reduce clinical symptoms, reduce the dose of hormones and anti-leukotriene used, shorten the use cycle, and improve the therapeutic efficacy.
ABSTRACT
Objective@#To explore the prenatal dietary and environmental risk factors in children aged 6-16 years with asthma (CWA) comorbid neuropsychiatric disorders.@*Methods@#This cross-sectional study was conducted from March 2016 to March 2017.CWA aged 6 to 16 years were recruited as the study participants at the Outpatient Asthma Unit of Guizhou Provincial People′s Hospital, China.Informed consent was obtained from their parents, and their parents were invited to participate in the Mini International Neuropsychiatric Interview of children and adolescents (MINI Kid) to assess the current neuropsychiatric disorders.Meanwhile, the questionnaires information about prenatal diet and environment were collected from their mothers as well.Patients were divided into 2 groups, one group with asthma comorbid neuropsychiatric disorders and the other with asthma only.Single factor analysis and multivariate non-conditional Logistic regression analysis were used to determine the risk factors associated with neuropsychiatric comorbidity.@*Results@#The study consisted of 261 patients (male: 163 cases, female: 98 cases) with asthma, with the age of (11.25±3.12) years, the rate of asthma comorbid neuropsychiatric disorders was 26.4% (69/261 cases). Single factor analysis showed that prenatal tobacco smoke exposure, winter coal combustion, food additives had statistically significant differences between the 2 group (χ2=7.385, 3.993, 4.529, all P<0.05), the other factors were not significantly different between two groups (all P>0.05); multivariate analysis indicated that prenatal tobacco smoke exposure was the independent risk factor for neuropsychiatric comorbidity in CWA (OR=5.098, 95%CI: 1.089-23.871, P=0.039).@*Conclusions@#The result revealed that the prenatal tobacco smoke exposure is the independent risk factor for neuropsychiatric comorbidity in CWA, need to enhance the propaganda and education of negative effects for parents should be enhanced during pregnancy to diminish the prevalence.

ABSTRACT
Objective To explore the effects of arsenic exposure on learning and memory and its potential mechanism in rats.Methods Water-based arsenic-exposed rat models were established on 4-l0 postnatal days.The experimental animals were divided into 4 groups (10-12 cases in each group):the control group,the 15 μg/L As2O3 water group,the 30 μg/L As2O3 water group,and the 45 μg/L As2O3 water group.Cognitive functions were examined with the Morris water maze,exploratory behavior was detected by the exploratory behavior test.The hippocampus of pups from each experimental group was sectioned at various time points after arsenic exposure.The morphologies and neurogenesis of the neurons in the hippocampus CA1-CA3 region and dentate gyrus (DG) were observed by hematoxylin-eosin staining,Nissl staining,and doublecortin (DCX) immunostaining at different time points after arsenic exposure.Results Compared with the normal control group,the escape latency of the rats in the arsenic-exposed group was prolonged.The average escape latency of the rats in the normal control group,15 μg/L As2O3 group,30 μg/L As2O3 group and45 μg/L As2O3 group were (17.00±9.53) s,(35.89 ±19.81) s,(26.60 ±18.84) s,and (33.79 ±18.08) s,respectively,and the difference among 4 groups was statistically significant (F =3.591,P ＜ 0.05),and the residence time in the original target quadrant was shortened,respectively,(38.93 ± 8.33) s,(36.03 ± 16.25) s,(29.85 ± 9.27) s,and (29.84 ± 10.16) s,respectively,and there was no significant difference among 4 groups (F =1.681,P =0.187).HE staining and Nissl staining showed that pathological changes such as edema,degeneration and necrosis were observed in the hippocampal CA1 area and CA2 area as well as dentate gyrus cells in rats exposed to arsenic in the acute phase.The higher the concentration of arsenic exposure,the more obvious the cell structure disorder was.However,5 weeks after exposure,the pathological changes in hippocampal neurons in the arsenic-exposed group gradually returned to normal.Immunohistochemistry showed that the expressions of DCX in the CA1,CA2 and dentate gyrus of rats exposed to arsenic decreased significantly 24 h after arsenic exposure,especially in the 45 μg/L group.Five weeks after arsenic exposure,there was no expression in the hippocampal CA1-CA3 area,and there was still a small amount of expression in the dentate gyrus.Conclusions Postnatal low-concentration arsenic exposure may impair learning and abnormal germination of neurons in the hippocampal dentate gyrus may be the underlying mechanism.
ABSTRACT
Objective To investigate the epidemiological status of visceral leishmaniasis in Hamangou coal mine area of Korla City of Xinjiang Uygur Autonomous Region.Methods Based on a hint of possible existence of patients, a retrospective survey was carried out house by house to find cases with suspected signs/symptoms of the disease.Meanwhile, a survey on current status was conducted, including physical examination(liver and spleen palpation) to those less than 15 years-old, leishmanin skin test and rk39 immunochromatographic strip test for part of the residents.Bone marrow smears were examined for the cases with clinical signs/symptoms and positive rk39 strip test.Sandflies were collected using routine methods in and around the area, identified, and dissected to find infection of promastigotes.Results Leishmanin skin test was performed in 185 people with a positive rate of 21.1%(39/185), 39 out of 140 local residents who have lived there for more than 6 years showed positive(27.9%) , while all residents who have lived less than 6 years and children under 5 years old were negative.Of the 81 children under 15 years old with a negative skin test, one showed positive for rk39 strip test, and leishmania body was found in the bone marrow smear of this case, so confirmed as visceral leishmaniasis.12 sandfies were identified as Phlebotomus alexandri, and natural infection with promastigotes was found in one sandly.Conclusion The investigation confirms that visceral leishmaniasis is endemic in the Hamangou coal mine area.
