Objective To study the expression of thymic stromal lymphopoietin(TSLP) and the activation of DCs in OVA-induced murine asthma model, and investigate the effects and underlying mecha-nisms of TSLP on lung inflammation. Methods Thirty BALB/c mice were randomly divided into control group, OVA group and TSLP neutralizing antibody treated group. The asthma model was evaluated by airway responsiveness and histological analysis of lung tissues ; The levels of TSLP mRNA in lungs were determined by quantitative real-time PCR; The expression of TSLP in lungs were determined by immunohistochemistry and Western blot; The expression of CD40, CD80, CD86 in BALF was detected by FACS. Results Both the histological analysis of lung tissues and the airway responsiveness were all consistent with the characteris-tic of murine asthma model. The expression of TSLP and TSLP mRNA in the OVA group was significantly in-creased compared with blank group. The expression of CD40, CD80, CD86 in BALF from OVA group was increased significantly compared with the control group. Furthermore, treating mice with TSLP neutralizing antibody reduced the expression of CD40, CD80, CD86 on dendritic cells, and IL-4, IL-5, IL-13 in the OVA group. Conclusion Our study indicate that TSLP was highly expressed in the bronchial epithelia of murine asthma model, via upregulation of CD40, CD80, CD86, induce DCs to active CD4~+ T cells and pro-duce type 2 responses, so that aggravating the lung inflammation of asthma. Blocking TSLP is capable of in-hibiting the production of Th2 cytokines, thus presents a promising strategy for the treatment of asthma.

Objective To explore the growth and developmental parameters and behavioral characteristics of rhesus monkeys during the first year of birth and to establish the background data.Methods A total of 18 (♂=11,♀=7 ) infant rhesus monkeys born from individually caged mothers and with known genetic background and postnatal days were monitored monthly for body weight, body height, head circumference, chest circumference, forelimb length, hind limb length, crown-rump length, tail length and anal-genital distance from postnatal day ( PND) 1 to 360, while hematology, blood chemistry and lymphocyte subsets were examined on PND 28, 175 and 360, and finger maze test was carried out on PND 208.Results The body weight showed linear growth with no significant difference between genders (P>0.05). Except for the anal-genital distance of male infants was significantly greater than that of female infants ( P<0.01 ) , no significant differences were observed between sexes in other morphological parameters.No significant differences of hematology were seen between genders (P >0.05).Compared with that at PND28, TP and BUN were significantly increased (P<0.01) while ALP decreased with no significant difference (P>0.05) at PND 175 and 360.Compared with that at PND28, CD4 +and CD4 +/CD8 +were significantly decreased ( P<0.01) while CD8+significantly increased ( P<0.01) at PND175 and 360.The number of sessions to solve task 2 in learning test was significantly greater than other tasks with females significantly less than males ( P<0.05) .The females had higher correct rate than males in the 2-day random memory test (P<0.05).Conclusions Body weight and morphological parameters show a linear growth.The PND.The RBC, HGB, LYMPH, TP, BUN, ALP, CD4 +, CD8 +and CD4 +/CD8+in hematology, blood chemistry and lymphocyte subsets show relevant changes to the growth and development of organs and systems in infants, which should be highly concerned in drug evaluation.The finger maze test indicates that female infants have better reversal learning and long-term memory than male infants.Background data and behavioral characteristics of infant rhesus monkeys during the first 12 months of birth are established in this study, which provide useful reference and support the evaluation of developmental and reproductive toxicity of drugs in rhesus monkeys.

Objective To observe the effect of the conditioned medium obtained from the coculture of astrocytes and β-amyloid (Aβ1-40)-induced apoptotic PC12 cells on the neuronal differentiation efficiency of neural stem cells (NSCs), and investigate the possible involvement of the neurotrophins proteins including brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF)and neurotrophin-3 (NT-3) in the induced differentiation of the NSCs. Methods PCI2 cells wereinduced by Aβ1-40 for different time lengths (0, 4, 6, 12, and 24 h), and after detection of the apoptotic rates using flow cytometry, the cells were cocultured with astrocytes for 2 days. The astrocyte-conditioned medium (ACM), after analysis of the neurotrophins proteins using erLzyme-linked immunosorbent assay (ELISA), was mixed with DMEM/F12 medium at the proportion of 1:3 to induce the differentiation of the NSCs. The cell differentiation was identified by laser confocal microscopy, NSE immunofluorescent labeling, and neuronal counting. Results Flow cytometry showed that induction by Aβ1-40 for 6 h resulted in the highest apoptosis rate of PC12 cells (P<0.05). BDNF content in the ACM derived from the coculture of astrocytes and the PC12 cells induced for 6 h was significantly increased, and the NSCs induced in this ACM showed the highest neuronal differentiation rates, showing significant difference from those induced by other ACMs (P<0.05). Conclusion The ACM derived from the coculture of Aβ1-40-induced PC12 cells and astrocytes can increase the neuronal differentiation rates of NSCs in vitro, and BDNF in the ACM may play a role in this process.

OBJECTIVETo study the effects of Erlong Zuoci Pill (, ELZCP) and its disassembled: prescriptions on gentamicin (GM)-induced ototoxicity model in vitro.

METHODSAfter the spiral organ of cochleae: of newborn mice (postnatal days: 2-3) cultured for 24 h, GM alone or combined with water extracting-alcohol precipitating solution of ELZCP or with its disassembled prescriptions was added. Hair cells were observed under a fluorescence microscope after TRITC-phalloidin staining, and the cochlear hair cell loss rate was calculated by counting the whole cochlear hair cells and analyzed by whole cochlear hair cells analyzing software.

RESULTSGM induced cochlear outer hair cells (OHCs) and inner hair cells (IHCs) injuries in a dose-dependent manner, and they were significantly different as compared with those in the normal control group (P<0.05, P<0.01). ELZCP at the concentration of 0.003-3 mg/mL could decrease the hair cells loss induced by the 0.3 mmol/L GM (P<0.05, P<0.01), the effects was in a dose-dependent manner, and the concentration of 0.3 mg/mL showed the optimal protective effect. For the ELZCP disassembled prescriptions, Liuwei-Dihuang could decrease OHC loss rate than that in the 0.3 mmol/L GM model group (P<0.05), but the OHC loss rate was still higher than that in the ELZCP group (P<0.01), which indicated that the protective effect of hair cells by Liuwei-Dihuang was not better than that of ELZCP. Poria decreased OHC loss rate from 72.1 % +/-3.7 % to 58.8 %+/- 8.2 % (P<0.05).

CONCLUSIONSELZCP could play a role in antagonizing the injury of cochlear hair cells induced by GM ototoxicity,: and its disassembled prescriptions, Liuwei-Dihuang was the main component to protect the cochlear hair cells from GM-induced ototoxicity, and Magnetitum combined with Radix Bupleurui could strengthen the action of the whole prescription; Poria could reduce GM-induced OHC loss.

BACKGROUNDPolypharmacy and potentially inappropriate medications (PIMs) are prominent prescribing issues in elderly patients. This study was to investigate the different prevalence of PIM use in elderly inpatients between 65-79 years of age and 80 years or older, who were discharged from Geriatric Department in West China Hospital.

METHODSA large-scale cohort of 1796 inpatients aged 65 years or over was recruited. Respectively, 618 patients were 65-79 years and 1178 patients were 80 years or older. Updated 2012 Beers Criteria by the American Geriatric Society was applied to assess the use of PIM among the investigated samples.

RESULTSA review of the prescribed medications identified 686 patients aged 80 years or older consumed at least one PIM giving a rate of 58.2%. Conversely, 268 (43.4%) patients aged 65-79 years consumed at least one PIM (χ2 = 40.18, P < 0.001). Patients aged 80 years or older had higher hospitalization expenses, length of stay, co-morbidities, medical prescription, and mortality than patients aged 65-79 years (all with P < 0.001). Patients aged 80 years or older were prescribed with more benzodiazepines, drugs with strong anticholinergic properties, megestrol, antipsychotics, theophylline, and aspirin. In multiple regression analysis, PIM use was significantly associated with female gender, age, number of diagnostic disease, and number of prescribed medication.

CONCLUSIONSThe finding from this study revealed that inpatients aged 80 years or older encountered more PIM use than those aged 65-79 years. Anticholinergic properties, megestrol, antipsychotics, theophylline, and aspirin are medications that often prescribed to inpatients aged 80 years or older. Doctors should carefully choose drugs for the elderly, especially the elderly aged 80 years or older.

Objective To investigate the effects of Longdan Xiegan Decoction on the expression of Notch signaling-related genes in rats with experimental autoimmune uveitis (EAU).Methods Totally 24 Lewis rats were randomly divided into normal control group,EAU model group and Longdan Xiegan Decoction treatment group.A rat model of EAU was established in the EAU model group and Longdan Xiegan Decoction treatment group,followed by intragastrical administration of Longdan Xiegan Decoction in the latter group after successful modeling.On day 12 after different treatments,the spleen and lymph nodes were isolated from rats of all the three groups for the collection of CD4 + T ceils,and the levels of both Th17 and Treg cells were analyzed by flow cytometry to calculate the ratio of Th17 to Treg cells.Meanwhile the levels of Notch1,Notch2,Notch3,Notch4 mRNAs expression were monitored by qRT-PCR.Moreover,the expressions of Notch signaling-related proteins were further detected using ELISA technique.Results Flow cytometry showed increased Th17 cell level but decreased Treg cell level in the EAU model group when compared with the normal control group.However,after treatment with Longdan Xiegan Decoction,the Th17 level was decreased,whereas the Treg level was increased,and the ratio of Th17 to Treg gradually restored to equilibrium when compared to EAU model group.qRT-PCR results showed that the expression levels of Notch1,Notch2 and Notch4 mRNAs in Longdan Xiegan Decoction treatment group were significantly higher than those in the normal control group (all P ＜ 0.01),but lower than those in EAU model group on day 12 after treatment (all P ＜ 0.01),without Notch 3 expression in the spleen and lymph nodes.In addition,Notch 1,Notch 2 and Notch 4 protein levels of the spleen and lymph nodes in Longdan Xiegan Decoction treatment group showed the similar tendency as compared to those of Notch 1,Notch 2 and Notch 4 mRNAs (all P ＜ 0.01),and the expression of Notch 3 protein was still not observed.Conclusion Longdan Xiegan Decoction can effectively relieve the imbalance of Th17/Treg cells in EAU rats,and its mechanism may involve the differentiation of naive CD4+ T cells into Th17 and Treg cells,which is regulated by Notch signaling.

OBJECTIVETo investigate the feasibility of interphase FISH in the routine clinicopathological practice and its values in the differential diagnosis of lymphomas.

METHODSA total of 74 fresh tissue samples clinically suspicious of lymphoma were investigated by FISH using three probes including IgH/bcl-2, IgH/CCND1 and API2/MALT1, corresponding the translocation t(14;18), t(11;14) and t(11;18) respectively. The results of FISH were analyzed and compared with the histopathologic diagnosis.

RESULTSHistological evaluation eventually confirmed that there were 62 cases of lymphoma and 12 cases of reactive lymphoid processes. The translocations were detected in 7 cases in 62 cases of lymphoma: 3 demonstrated t(14;18) including 2 cases of follicular lymphomas and 1 nodular sclerosing Hodgkin lymphoma. Four cases had t(11;14) including mantle cell lymphoma (2 cases), follicular lymphoma (1 case) and small cell lymphoma (1 case). A lymphoid hyperplasia case showed detectable t(14;18). All 25 cases of DLBCL showed no evidence of t(14;18). Amplification or loss of regional genes was seen more often in malignant than in the benign cases.

CONCLUSIONInterphase FISH offers useful ancillary technology that plays an important role in differential diagnosis and classification of lymphoma.
