Inflammatory Bowel Disease(IBD) is concerned with heredity,dysimmunity,environment and others,its characterized by chronic or relapsing inflammation within the gastrointestinal.IBD including two independent disease ulcerative colitis and crohn′s disease.In recent years with the incidence of IBD increased year by year,more women in reproductive age facing drug treatment.This article elucidated the effect of IBD and its treatment on perinatal.

This report analyzes the status of schistosomiasis epidemic,surveillance and challenges in transmission?interrupt?ed areas of Jiangxi Province. There are 24 schistosomiasis transmission interrupted counties(cities,districts)among 39 endem?ic counties(cities,districts). Among the 24 counties,there are 6 counties with Oncomelania hupensis snails and 461 villages endemic,with 1.29 million residents. Since 2009,there have not been acute and chronic cases of schistosomiasis and all the pa?tients are historical advanced schistosomiasis cases. The area with snail habitats is 37.02 hm2. Since 2015,the schistosomiasis surveillance has covered the entire transmission interrupted areas. However,there are still many challenges,such as endemic in?stability,weak surveillance capacity,lack of surveillance awareness and other issues. Towards the schistosomiasis elimination, the surveillance should be based on the snail monitoring mainly,supplemented by the mobile population monitoring,and in ad?dition,the capacity building,standardized report of endemic,and snail habitat reform should also be further strengthened.

Methods People more than 60 years old in 14 provinces, 22 districts were investigated with a self-designed questionnaire, and a hearing test was also done for every subject. Results Among all the subjects, the etiological factors of hearing loss were otitis media (10.5%), hereditary deafness (2.9%), noise-induced hearing loss (3%), ototoxic deafness (6.4%), traumatic deafness (2%), presbycusis (33.8%), sudden deafness (1%) and other reasons (36.2%), respec-tively, with 11.3%unknown. Conclusion Presbycusis is the main reason of hearing loss for old people, and otitis media is the second. The cause of hearing loss is different with ages, districts, and whether in rural areas.

Objective To explore the effects of patient participation-based dietary intervention on nutritional status for patients with gastrectomy.Methods Fifty-two patients with gastrectomy were randomly assigned to the intervention group(n=26) and the control group(n=26).All patients were given general dietary guidance,and patients in the intervention group were provided patient participation-based dietary intervention(PPDI) as well.Height,body weight and body mass index(BMI) were recorded at baseline,2 weeks and 12 weeks after intervention,using PatientGenerated Subjective Global Assessment(PG-SGA),Diet-Related Symptom Scale,Adherence to Dietary Scale and a 3-day food diary.Results There was no obvious change in body weight and BMI before and after 12-week intervention,while outcomes in the control group gradually decreased.For time effect,there was significant difference in PG-SGA between two groups(P＜0.05).For between-group effect,there were significant differences in diet-related symptoms(P＜0.05),dietary intake(P＜0.05) and adherence to dietary(P＜0.05) between two groups.Conclusion Patient participation-based dietary intervention can improve nutritional status for patients with gastrectomy.

Erythromycin A is a clinically important macrolide antibiotic with broad-spectrum activity. Its biosynthesis involves the formation of the 14-membered skeleton catalyzed by polyketide synthases, and the modification steps such as hydroxylation, glycosylation and methylation. Based on the understanding of the biosynthetic mechanism, it is reliable to genetically manipulate the erythromycin A-producing strain for production improvement and structure modification. In this paper, we reviewed the progress regarding erythromycin A in high-producing strain construction and chemical structure derivation, to provide insights for further development.

There were statistically significant post-treatment differences in the skin lesion score and the pruritus score between the treatment and control groups (P<0.01). The total efficacy rate was 81.8% in the treatment group and 60.5% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Fire needling plus moxibustion is an effective way to treat prurigo nodularis.

Objective:To observe the effect of timosaponin AⅢon the proliferation of cultured melanoma B16 and A375 cells and nitrite produced from macrophage activation. Methods:MTT assay was adopted to detect the cell growth inhibition. The morphological changes of B16 and A375 cells were observed under an inverted microscope. Nitrite production of activated mouse macrophages induced by lipopolysaccharide ( LPS) plus IFN-γ was measured by Griess assay. Results: Timosaponin AⅢ could significantly inhibit the growth of B16 cells at the concentration of 16 μmol·L-1 after the 48- and 72-hour treatment, and significantly inhibit the growth of A375 cells at the concentration ranged from 4 to 16 μmol·L-1 after the 48-and 72-hour treatment. Shrinkage, vacuoles and necrosis of B16 and A375 cells were observed after the 48-and 72-hour treatment by 16μmol·L-1 timosaponin AⅢ,the other concentration of timosaponin AⅢ showed no notable effect on B16 cells and vacuoles of A375 cells appeared at the concentration from 4 to 16 μmol· L-1. Compared with RAW 264. 7 stimulated LPS plus IFN-γ,timosaponin AⅢ could significant inhibit nitrite production of macro-phage inflammatory cell model at the concentration of 10μmol·L-1(P<0. 01). Conclusion:Timosaponin AⅢcan inhibit the prolif-eration of melanoma B16 and A375 cells and macrophage inflammation,suggesting it has anti-tumor and anti-inflammatory effects . The anti-tumor effect of timosaponin AⅢ may be related to the inhibition of tumor inflammation.

Objective To study the risk factors for pulmonary fungal infection associated with chronic obstructive pulmonary disease (COPD),and evaluate the efficacy and safety of itraconazole for treatment of pulmonary fungal infection associated COPD.Methods A retrospective analysis were conducted on clinical data of 42 COPD patients who were confirmed pulmonary fungal infection in a respiratory disease department from September 1 ,2007 to May 31 ,2012,and 53 COPD patients who had no pulmonary fungal infection were as control.Results Of 42 patients with COPD and pulmonary fungal infection,8 were confirmed by histopathological examination,34 were confirmed by clinical diagnosis;6 were acute cases,36 were chronic cases;28 were positive for fungal detection,6 of whom were detected Candida albicans ,13 were detected Aspergillus ,7 were detected unclassified fungi,and 2 had mixed fungal infection.Univariate analysis showed that underlying diseases,long-term use of broad-spectrum antimicrobi-als,long-term use of glucocorticoid,hypoproteinemia,invasive procedure,invasive mechanical ventilation,diabetes mellitus,history of invasive fungal infection were major risk factors for pulmonary fungal infection associated with COPD.After patients were treated by itraconazole,the improvement rate of clinical symptoms was 66.67%,fungal eradication rate was 60.71 %,total effective rate was 64.29%.Of 28 cases with positive fungal detection,the im-provement rate of clinical symptoms,fungal eradication rate,and total effective rate was 71 .43%(n=20),60.71 %(n=17),and 67.86%(n=19)respectively.Itraconazole had good therapeutic efficacy on acute and chronic pulmo-nary fungal infection associated with COPD.Adverse drug reaction rate was 23.81 %,most were mild and reversi-ble,and had no obvious impact on the treatment.Conclusion Itraconazole has positive clinical efficacy on treating pulmonary fungal infection associated with COPD,it is highly safe.

Objective:To investigate the value of preoperative slight decline of the pulmonary function in predicting postoperative cardiopulmonary complications (PCC) after left total pneumonectomy of lung cancer patients to guide the clinical surgery of lung can-cer. Methods:Clinical data of 200 lung cancer patients after left total pneumonectomy were retrospectively analyzed. These patients were divided into two groups (PCC and non-PCC) based on the incidence of postoperative cardiopulmonary complications within 1 month after the cancer resection. The relationship between the preoperative slight or moderate to severe reduction of pulmonary func-tion and postoperative complications was explored. The correlation between the preoperative slight decline of the pulmonary function index and PCC was also analyzed. Results:Among the 200 patients, 35, 45, and 120 demonstrated normal, slightly, and moderately to severely reduced pulmonary functions, and 28.6%, 53.3%, and 62.5% showed PCC within 1 month after the surgical resection (χ2=12.611, P=0.002). Significant differences in the slightly reduced pulmonary function parameters MVV% (70% ≤ MVV<80%) and FEV1%(70%≤FEV 1%<80%) were observed between those without and with complications (P=0.028 and 0.014). Further analysis indicated no significant difference between the patients with preoperative slight reduction of FEV1%only or of MVV%only (P>0.05). However, statistically significant differences were observed when both FEV1%and MVV%were slightly reduced (χ2=6.598, P=0.010). Conclusion:The preoperative slight reduction values of FEV1%and MVV%were the risk factors in predicting PCC after left pneumo-nectomy in lung cancer patients. The slightly reduced FEV1%or MVV%alone cannot influence PCC. Both slightly reduced FEV1%and MVV%were the risk factors of PCC. Perioperative management should be strengthened for these patients to lower the incidence of PCC.
