This study was designed to analyze the effect of the mitochondrial respiratory pathways of Candida albicans (C.albicans) on the biofilm formation.The 2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) reduction assay was used to measure the metabolic activities of biofilms formed by the C.albicans which were cultured in the presence of respiratory pathways inhibitors.The biofilms formed by the wide type (WT),GOA1-deleted (GOA31),GOA1-reconstituted (GOA32),AOX1a-deleted (AOX1) and AOX1b-deleted (AOX2) C.albicans strains were examined by the XTT reduction assay and fluorescence microscopy.The expression of adhesion-related genes BCR1,ALS1,ALS3,ECE1 and HWP1 in the biofilms formed by the above five C.albicans strains was detected by real time polymerase chain reaction.It was found that the metabolic activity of biofilms formed by C.albicans was decreased in the presence of alternative oxidase inhibitor whereas it was increased in the presence of classical mitochondrial respiratory pathway complex Ⅲ or complex Ⅳ inhibitor.AOX1 strain produced scarce biofilms interspersed with few hyphal filaments.Moreover,no significant changes in the expression of BCR1 and ALS3 were observed in the AOX1 strain,but the expression of ALS1 and ECE1 was down-regulated,and that of HWP1 was up-regulated.These results indicate that both AOX1 and AOX2 can promote the biofilm formation.However,AOX1a primarily plays a regulatory role in biofilm formation in the absence of inducers where the promoting effect is mainly achieved by promoting mycelial formation.

OBJECTIVETo observe the therapeutic effect of Zhifeng Huatan Pingxiao recipe (ZHPR) in treating attack stage of child asthma.

METHODSSixty child asthma patients with attack of mild and moderate degree were randomly divided into the treated group (40 patients treated with ZHPR) and the control group (20 patients treated with western medicine). The therapeutic effect and laboratory indexes, including peripheral eosinophil count (EOS), serum immunoglobulin E (IgE) and plasma endothelin (ET), before and after treatment were observed.

RESULTSThe total effective rate in the treated group was 72.5%, which was not different to that in the control group (P > 0.05). The therapeutic effect between different TCM types (heat and cold types) in the treated group was not different significantly (P > 0.05). ET, IgE and EOS levels all lowered after treatment in the treated group, but as compared with those in the control group, the difference was insignificant (P > 0.05).

CONCLUSIONThe therapeutic effect of ZHPR in treating child asthma attack stage is equivalent to that of western medicine, it shows actions in improving laboratory indexes.

Three bactreiophages of Pseudomonas aeruginosa were isolated from sewage and named as PaP1, PaP2 and PaP3. All belong to double-strand DNA phages, their genome is about 47kb, 34kb and 24kb respectively. The titre (pfu/mL) of three phages is respectively 109, 1011 and 1011, PaP1 is lytic phage, both PaP2 and PaP3 are lysogenic. Under electron microscope, All show icosahedral heads with diameter of 70nm, 55nm and 65nm respectively. PaPl belongs taxonomically to Myoviridae, and both of PaP2 and PaP3 belong to Pedoviridae. The phage-re-sistance and substitution phenomenon of the resistant flora for the sensitive were observed, and the mutation frequence of Pseudomonas aeruginosa resistant to the phage is about 1.4 ? 10-7 ~ 7.9 ?10-7 determined by end-point -titer method.

Objective To detect the mutations of ATP2C1 gene in patients with Hailey-Hailey dis- ease (HHD).Methods PCR and direct sequencing were performed in 17 patients and 120 healthy controls to screen the mutations in the exons of ATP2C1 gene.Results Eight mutations were identified in nine probands, including three deletion mutations (nt1464-1487 del/nt1462-1485del,1523delAT,2375delTTGT),three splice site mutations (360—2A→G,1415—2A→T,2243+2T→C) and two missence mutations (C920T and G1942T).None of the above mutations was found in the controls.Conclusion Eight specific novel mutations were identified in nine probands of HHD,which could be causative factors of the disease.

OBJECTIVETo observe the evolutionary tendency of brain derived neurotrophic factor (BDNF) of the limbic system in post-stroke model rats and the intervention effect of Yinao Jieyu Recipe (YJR).

METHODSMale Wistar rats were randomly divided into the normal control group (n =6), the sham-operation group (n =7), the multiple cerebral infarction (MCI) group (n =10), the post-stroke depression (PSD) group (n =10), the Chinese medicine (CM) treatment group (n =10), and the Western medicine (WM) treatment group (n =10) according to random digit table after open-field testing. Rats in the normal control group were routinely fed. 0. 3 mL normal saline was intravenously pushing from the external carotid artery to rats in the sham-operation group, and distilled water administered to them by gastrogavage. Each dose allogenic microthrombi were in vitro pushed to rats in the rest groups from the external carotid artery. The PSD model was duplicated by 21-day chronic unpredictable mild stress (CUMS) and single cage feeding in the PSD group 7 days after surgery. After preparing models rats in the CM group and the WM group were administered with YJR and Nimodipine respectively for 4 successive weeks. Changes of BDNF and the intervention effect of YJR were observed at week 1, 2, and 4 after intervention.

RESULTSImmunohistochemical results of BDNF showed, compared with the normal control group, expression levels of BDNF in the hippocampus, hypothalamus, and amygdala decreased in the MCI group at week 2 and 4 (P <0. 01 , P <0. 05) ; expression levels of BDNF in each part decreased in the PSD group at week 1-4 (P <0.01). Compared with the MCI group, expression levels of BDNF in each part decreased in the PSD group at week 1-4 (P <0. 01). Compared with the PSD group, expression levels of BDNF in each part increased in the CM group at week 1-4 (P <0. 01).

CONCLUSIONBDNF changes existed in post-stroke model rats, and YJR could slow down this progress.

The aim of this study was to investigate the clinical feature of mucosa-associated lymphoid tissue lymphoma and clarify the relationship between the pathological, clinical features, the expression of API2-MALT1 and the prognosis. A number of factors including pathological characters, grade, stage, prognosis and treatment of 49 cases of MALT lymphoma were analyzed, and the API2-MALT1 rearrangement was detected by RT-PCR. The results showed that 49 patients were diagnosed as MALT lymphoma, in which median age was 52.4 years. The percentage of patients older than 50 years was 67.3%. The majority of tumors were found in stomach (22 cases), intestine (13 cases), thyroid (6 cases) and so on. Among 49 patients, stage I, II was 77. 6%, stage III, IV was 22.4%. API2-MALT1 rearrangement were found 38.1% in low grade, and 12.5% in transform type. Among 18 patients with gastric MALT lymphoma, 9 cases (50.0%) were helicobacter pylori (HP) positive and received antibiotic treatment. The 3 years overall survival was 93.8%. It is concluded that MALT lymphoma is often seen in older patients, most of them were in low grade with slow progression. The site, grade, stage and molecular genetic changes are important prognostic factors, which can contribute to choosing suitable treatment for patients with MALT lymphoma. The antibiotic treatment is effective for patients with positive HP.
