OBJECTIVETo investigate Salmeterol/Fluticasone Propionate and Totropiumi treatment of Sillicosis merger Asthma.

METHODS30 patients with Sillicosis merger Asthma were randomly divided into group Salmeterol/Fluticasone Propionate( Single group) ( n=14) and group Salmeterol/Fluticasone Propionate and Totropiumi (Joint group) ( n= 16), patient in single group were only given Salmeterol/Fluticasone Propionate (50 f.Lg Bid) inhaling,and those in Joint group were given Salmeterol/Fluticasone Propionate (50 f.Lg Bid) and Totropiumi ( 18 f.Lg Qd) inhaling. The treatment was last for 6 months.Before the treatment,evaluation of the two groups of Sillicosis installment,determination their foungation lung function and ACT score .. After the cause of treatment, lung function FEV10/FVC(% ), FEV10 pred%, FEV10(ml), ACT score, the incidence of side effects of two groups were compared and analyzed.

RESULTThe two groups before the treatment of lung fuction and ACT score had no statistically significant difference. The two groups after treatment of lung fuction FEV10/FVC (% ),FEV10 pred%, ACT score obviously higher than before treatment (P<0.05), Joint group in FEV1/FVC(% ), ACT score significantly higher than in Single group (?<0.05), Joint group acute attack times(0.98±0.79)/time lower than Single group (2.10 ± 0.81 )/time (t=3.86,P<0.05). There were no significant side effect in two groups.

CONCLUSIONSalmeterol/Fluticasone Propionate or the combination of Salmeterol/Fluticasone Propionate and Totropiumi can improve lung function and clinical symptoms of patients with Sillicosis merger Asthma. It is also better that the combination of Salmeterol/Fluticasone Propionate and Totropiumi obviously improve clinical symptoms of patients and reduice acute attack times.

Objective: “Same treatment for different diseases” is a unique treatment strategy under the guidance of traditional Chinese medicine (TCM) theory. Codonopsis Radix (Codonopsis pilosula, Dangshen in Chinese) with spleen-fortifying effect was employed to understand the strategy of “Same treatment for different diseases”, based on its common mechanism in the treatment of gastric diseases including gastric ulcer, gastritis and gastric cancer via network pharmacology research. Methods: Network pharmacology research methods were used to analyze the interaction network and potential mechanisms of Dangshen in treating gastric ulcer, gastritis and gastric cancer. The active components and their target proteins of Dangshen were integrated from TCMSP, BATMAN-TCM databases. The targets of gastric ulcer, gastritis and gastric cancer were collected through GeneCards, PubMed, TDD and DisGeNET Database. Through screening, the key components and the key targets of Dangshen in treating gastric ulcer, gastritis and gastric cancer were obtained. After KEGG pathway analysis and GO analysis, the important pathways and biological processes were analyzed. Results: Through data and literature mining, the common and specific pharmaceutical effects and mechanism of Dangshen were summarized in these three gastric lesions. It was shown that Dangshen mainly acted on gastric ulcer, gastritis and gastric cancer through the overall regulation of the PI3K-AKT signaling pathway. With the development of the disease, it will gradually increase the control of inflammation through TNF, NF-κB and other inflammation-related signaling pathways to reduce inflammatory damage. For tumorigenesis, it pays more attention to inhibiting the ErbB signaling pathways to reduce the proliferation and migration of tumor cells. In addition, Dangshen's regulation of HIF-1 signaling pathway may also be beneficial for the treatment of gastric ulcer, gastritis and gastric cancer. Conclusion: Dangshen achieves spleen-fortifying effect on gastric diseases including gastric ulcer, gastritis and gastric cancer through multiple targets in multiple pathways, especially PI3K-AKT pathway and HIF-1 pathway. It could provide a scientific basis for understanding the strategy of “Same treatment for different diseases” in traditional Chinese medicine.

OBJECTIVETo investigate the effect of ceftriaxone on the intestinal epithelium and microbiota in mice in the early-life stage, as well as the recovery of the intestinal epithelium and reconstruction of intestinal microbiota in adult mice.

METHODSA total of 36 BALB/C neonatal mice were randomly divided into control group and experimental group, with 18 mice in each group. The mice in the experimental group were given ceftriaxone 100 mg/kg every day by gavage within 21 days after birth. Those in the control group were given an equal volume of normal saline by gavage. Immunohistochemistry was used to measure the expression of Ki67, Muc2, and ZO-1 in the intestinal epithelium. qPCR and next-generation sequencing were used to analyze the overall concentration and composition of fecal bacteria.

RESULTSAfter 21 days of ceftriaxone intervention, the experimental group had a significant reduction in body weight, a significant reduction in the expression of Ki67 and ZO-1 and a significant increase in the expression of Muc2 in intestinal epithelial cells, a significant reduction in the overall concentration of fecal bacteria, and a significant increase in the diversity of fecal bacteria compared with the control group (P<0.05). Firmicutes was the most common type of fecal bacteria in the experimental group, and there were large amounts of Staphylococcus and Enterococcus. The experimental group had a certain degree of recovery of the intestinal epithelium, but there were still significant differences in body weight and the structure of intestinal microbiota between the two groups at 56 days after birth (P<0.05).

CONCLUSIONSEarly ceftriaxone intervention significantly affects the development of the intestinal epithelium and the construction of intestinal microbiota in the early-life stage. The injury of the intestinal microbiota in the early-life stage may continue to the adult stage and affect growth and development and physiological metabolism.

OBJECTIVETo determine the incidence and risk factors on HIV infection among injection drug users (IDU) in Dehong prefecture area of Yunnan province.

METHODSAn epidemiological cohort of HIV-negative IDU had been developed and followed since October, 2004. HIV new infections and related behaviors had been investigated every six months.

RESULTSBy the end of 2008, 760 HIV-negative IDU had been recruited and followed for a total of 1153.6 person-years. 47 new HIV infections were identified, with an overall incidence of 4.07/100 person-years during the follow-up period. The HIV incidence was 4.45/100 person-years during 2004 - 2006, 4.50/100 person-years in 2007 and 2.54/100 person-years in 2008. Both the behavior of drug injection and the HIV incidence among the cohort had substantially decreased during the follow-up period. Multiple regression analysis using Cox proportional hazard model indicated that people with Jing-po ethnicity (Hazard ratio, HR = 2.56, 95%CI: 1.06 - 6.19) and other minorities except for Dai (HR = 3.26, 95%CI: 0.89 - 11.96) were at higher risk for HIV infection than the people with Han ethnicity. People injecting drugs with (HR = 2.27, 95%CI: 0.98 - 5.25) or without (HR = 5.27, 95%CI: 2.25 - 12.34) needle sharing were at higher risk for HIV infection than those reporting having no drug injection behavior during the follow-up period.

CONCLUSIONBoth the behavior of drug injection and the HIV incidence among former IDU in Dehong prefecture area of Yunnan province had been decreasing during the four years. However, needle sharing remained the most important risk factor for HIV new infection among IDUs. IDUs with different ethnicities seemed to have different risks towards HIV infection.
