Probiotics as intestinal flora regulators are increasingly applied in clinical practice;however,the administration of probiotics in immunocompromised individuals is rarely reported.This article is aimed to review the benefits and risks of probiotics in immunocompromised individuals,such as HIV-infected individuals and patients with malignant tumors.The research evidence shows that probiotics can reduce the occurrence of different types of diarrhea,regulate the intestinal immune status and decrease the incidence of complications in immunocompromised patients.Randomized controlled clinical trials have shown that the risk of adverse events is not significantly increased in immunocompromised patients compared to those with intact immune status and the probiotics-related infections are only presented in case reports.

Objective To investigate the anticancer efficacy of dihydromyricetin (DMY)in gastric cancer cells SGC7901. Methods The DMY was puritied using RP-HPLC was almost 98%.The cell viability was assessed by CCK-8 Assay.The cell ap-optosis was assessed by flow cytometry.Using ultrasonic extraction with neutral water and reversed-phase high-performance liquid chromatography,DMY was purified from rattan tea.Results By using RP-HPLC,the purified DMY is almost 99%.DMY inhibi-ted the growth of tumor cells in the low concentration(≤ 1 mmol)with a dose-dependent manner(P <0.05 ).Further study on DMY showed that it induced apoptosis in SGC7901 cell line with a dose-dependent manner.Conclusion DMY is a potential thera-peutic agent for gastric cancer.

Objective:To share a drug treatment experience for multiple drug resistant Pseudomonas aeruginosa.Methods:A retrospective analysis of the pharmaceutical care participated by clinical pharmacist for one case of intervertebral space infection with multiple drug resistant Pseudomonas aeruginosa was carried out.Results:Pharmacists participated in the whole treatment process,made the combined antimicrobial regimen (fosfomycin + ceftazidime + ciprofloxacin),and adjusted the time sequence.As a result,satisfactory curative effect was obtained.Conclusion:The infection with multiple drug resistant Pseudomonas aeruginosa may be treated with the three-drug therapy.Clinical pharmacists can play a positive role in the treatment of complicated infections.

Objective: To investigate the effect of Tanreqing injections combined with azithromycin in the treatment of children bronchial pneumonia. Methods:Totally 56 cases of pediatric bronchial pneumonia were selected in our hospital from September 2012 to September 2013 and randomly divided into the observation group and the control group with 28 cases in each. The control group was with azithromycin treatment, and the observation group was with Tanreqing injections additionally. The effect and adverse reactions of the two groups were studied and compared. Results:In the observation group, the effective rate was 92. 9%, which was significantly higher than that in the control group(P<0. 05). The hospitalization time and the symptoms disappearance time in the observation group were significantly shorter than those in the control group (P<0. 05). The adverse reactions showed no significant difference be-tween the two groups. Conclusion:Tanreqing injections in the treatment of children bronchial pneumonia is rapid, effective and safe.

Four patients developed with wound infections,three of them getting better after treatment and one of them diagnosed with poorly differentiated adenocarcinoma and selected another operation.Conclusion Well-prepared、pre-operation,skillful operation and instrument procedure and postoperative nursing were critical to the success of operations.

Objective::To understand the resources distribution and varieties of crude drug Coptis chinensis Franch. on Chinese market to provide scientific basis for the resource conservation and variety collection and studies of the Chinese medicine. Methods:On the basis of literature survey, field investigation, mandatory survey and interview survey were conducted. Results:Due to the chan-ges in environment for many years and the predatory development in Coptis resources at the end of 20th century, the ecological environ-ment of wild Coptis resources changed significantly with destructed resources and decreased reserves, especially wild Yalian and Yun-lian were on the verge of extinction. The mainstream product on Chinese market was Weilian followed by Yunlian mainly used in small-scale medical clinic and medicine market in the distribution area, while Yalian commodity medicine could not found. Conclusion::The supply and demand on Coptis market should be stabilized to ensure herbalist interests. The production technology of Coptis need further improvement, cultivated area and suitable variety should be confirmed to guarantee the quality of Coptis medicinal materials. State should pay attention to the changes in Coptis resources and strengthen protection for wild Coptis resources to ensure the sustainable development of Coptis resources. Relevant government departments should guide the production of Coptis reasonably.

BACKGROUND: There has been increasing attention in the study of adolescent idiopathic scoliosis (ALS)and bone metabolism, which is accompanied by osteopenia and osteoporosis. Interleukin(IL) -6, a cytokine that strongly promotes bone resorption, participates in the regulation of bone metablism.OBJECTIVE: To explore the relationship between changes of bone mineral density(BMD) and serum IL-6 content in AIS.DESIGN: A controlled non-randomized concurrent study involving patients with AIS and and healthy volunteers.SETTING: The clinic and wards of the department of spinal surgery of a university-affiliated hospital.PARTICIPANTS: Thirty-six patients with AIS(6 males and 30 females aged 12 to 18 years) were treated in the Department of Spinal Surgery, Drum Tower Hospital, Medical College of Nanjing University from July to October 2003, who had a Cobb angle ranging from 34° - 109° and curvature of the thoracic spine. Thirty-six healthy adolescent volunteers(7 males and 29 females within the range of 13 - 18 years old) served as the control group.METHODS: The BMD was measured at L2- L4 and the proximal femur;(including the femoral neck, greater trochanter and Ward' s triangle) by dual-energy X-ray absorptiometry and serum IL-6 determined by enzyme-linked immunosorbent assay(ELISA).MAIN OUTCOME MEASURES: ① BMD of the lumbar spine and femur ② Comparison of serum IL-6 content of all the subjects.RESULTS: The BMD of AIS patients at L2- L4, femoral neck, greater trochanter and Ward' s triangle was 0.79±0. 12, 0.78±0. 12, 0.65± 0. 10, and 0. 69 ± 0. 13 g/cm2, respectively, all significantly lower than the corresponding measurements of the control group(1.09 ± 0. 11, 0.95 ± 0. 11,0. 78 ± 0. 10, and 0. 88 ± 0. 11 g/cm2, respectively, P ＜ 0. 001), whereas the serum IL-6 content in the patients was significantly higher than that in the control subjects ( P ＜ 0. 005). The changes of BMD at the lumbar spine and the three sites of femur were negatively correlated with serum IL-6 in AIS patients( P ＜ 0. 001 ), but not so in the control group( P ＞ 0.05).CONCLUSION: The BMD is decreased and serum IL-6 elevated in patients with AIS, and excessive secretion of IL-6 might be one of the important factors of osteopenia in AIS.

The O152 antigens of Escherichia coli contains a Glc-β-1,3-GlcNAc linkage within the repeating unit. The wfgD gene in E. coli O152 O antigen gene cluster had been demonstrated utilizing NMR technique to encode a glucosyltransferase which is responsible for the synthesis of Glc-β-1,3-GlcNAc linkage. In this study, a synthetic substrate analog of the natural acceptor substrate undecaprenol-pyrophosphate-lipid [GlcNAc-α-PO_3-PO_3-(CH_2)_(11))-O-phenyl]) was used as an acceptor and UDP-Glc as a donor substrate, and electrospray ionization tandem mass spectrometry(ESI-MS-MS) was used for the detailed structural characte-)rization) of the enzyme product. A systematic study was conducted on product to allow rationalization of the fragmentation) processes. The major fragments observed in the ESI-MS-MS spectra result from cleavage of glycosidic) bond and diphosphate moiety. The fragment originating from the nonreducing end of the product yields information on sequence). Cross-ring cleavages, which are very informative of the linkages of the monosaccharide residues constituting) the product, and "internal" cleavage ions which are derived from elimination of substituents from around) the pyranose ring, were also observed. This extensive fragmentation was shown that the expected Glc-β-1,3-GlcNAc linkage in the product, confirming that wfgD is in the form of UDP-Glc: GlcNAc-pyrophosphate-lipid β-1,3-glucosyltransferase.)
