Objective To study the expression and clinical significance of Notch3 and Notch intracellular domain (NICD) in ovarian carcinoma and the effects of N-[N-(3 ,5-difluorophenyl) acetyl-L-alanyl]-S-phenyl glycine t-butyl ester (DAPT), a γ-secretase inhibitor on the proliferation and apoptosis in OVCAR3, A2780 ovarian carcinoma cell lines. Methods Western blot was used to detect the expression of NICD in the tissues from 58 ovarian carcinomas patients and 21 normal ovarie, who were admitted in Peking University First Hospital from July 2006 to June 2009. Immunohistochemistry was also used to detect the expression of Notch3 in these tissues. The relationship with clinical features of ovarian carcinoma was also analyzed. Proliferation of OVCAR3 and A2780 ovarian cancer cells was determined by methyl thiazolyl tetrazolium (MTT) assay, cell cycles and apoptosis and index of proliferation were detected by flow cytometry method. The expression of NICD in OVCAR3 and A2780 cells incubated with DAPT was detected by western blot. Results (1)The expression level of NICD in ovarian carcinomas was significantly higher than that in normal ovarian tissues (1.64 ±0. 19 vs. 0.98 ±0.20;P <0.05). The NICD expression was higher in ovarian cancers with low grade or advanced stage than those in high-middle grade or early stage,respectively (1.90 ± 0. 22 vs. 1.25 ± 0. 21,1.80 ± 0. 21 vs. 1.21 ± 0. 15; all P < 0. 05). The Notch3 protein was stained positively in cytoplasm, nuclear and cell membrane. The expression of Notch3 was higher in ovarian carcinomas than that in normal ovaries [78% (45/58) vs. 24% (5/21); P < 0. 01]. While,there were no stasistical difference in different pathological types, stages, differentiation of ovarian carcinoma. There was no difference between the patients with adjuvant chemotherapy or not. (2)After OVCAR3 and A2780 cells incubated with DAPT 24, 48, 72 hours, NICD expression was significantly lower than that in control group (P < 0. 05). The effects of DAPT inhibited the proliferation and prompted the apoptosis of OVCAR3 and A2780 cells were depended on the concentrations and times. Conclusions Notch3 and NICD may play a key role in the occurrence and progress of ovarian carcinoma. The mechanism of DAPT inhibited the proliferation and prompted the apoptosis of OVCAR3 and A2780 cells may be due to decreased the formation of NICD.

OBJECTIVETo observe the effects of electroacupuncture (EA) at "Dazhui" (GV 14) on Wnt-β-catenin signal pathway in annulus fibrosus cells in intervertebral disc in rats with cervical spondylosis.

METHODSForty SD rats were randomized into a control group, a model group, an EA group and a medication group, 10 rats in each one. Rats in the control group were treated with sham operation, only incision on local skin; rats in the remaining groups were made into cervical spondylosis models. After model establishment, rats in the control group and model group received fixed treatment under identical condition; rats in the EA group were treated with EA at "Dazhui" (GV 14), 30 min per treatment; rats in the medication group were treated with intragastric administration of meloxicam tablets. Treatments were both given once a day, and 14 days were taken as one session; there was an interval of 2 days between two sessions, and totally two sessions were given. After the treatments, immunohistochemistry was applied to measure the expression of Wnt, glycogen synthase kinase-3β (GSK-3β) and Axin in annulus fibrosus cells; western blot was used to test the expression of P-β-catenin.

RESULTSIn the control group, there were more positive cells of Wnt, GSK-3β and Axin, which were intensively distributed, deeply colored, and strongly positive; In the model group, there were less positive cells of Wnt, GSK-3β and Axin, which were sparsely distributed and weakly positive. The expression of Wnt, GSK-3β, Axin and P-β-catenin in the model group was less than that in the control group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin in the EA group and medication group was higher than that in the model group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin was not significantly different between EA group and medication group (all P > 0.05).

CONCLUSIONEA could delay the degeneration of intervertebral disc, which may be related to EA inhibiting signal pathway of Wnt-β-catenin.

Background Dry eye is a common disease worldwide.Cyclosporine A(CsA) is provided to be a immunosuppressive agent and is effective on dry eye.But in China,0.05％ CsA is not yet applied in dry eye treatment.Objective This study was to evaluate the efficacy and safety of 0.05％ CsA eye drops in the treatment of dry eye.Methods This was a randomized,double-blind,vehicle-controlled parallel group study.Forty eyes of 40 patients with moderate to severe dry eye were randomly divided into two groups,with the corresponding treatment of 0.05％ CsA eye drops or the vehicle emulsion.The patients in both the groups received non-preserved artificial tear.Symptoms and signs were observed before administration,(7±1),(28±2),(56±3),and (84±3) days and also 14 days after withdrawal.The clinical effective rate was considered as the primary outcome.The subjective assessment of the patients including total symptom scores and ocular surface disease index (OSDI) scores,Schirmer Ⅰ test (S Ⅰ t) with topical anaesthesia,tear film breakup time (BUT),rose Bengal and fluorescein staining scores were evaluated.The safety profile was evaluated by adverse events,visual acuity and ocular tolerance.Results At the end of this trial,the ocular symptoms scores,conjunctival hyperemia,BUT,S Ⅰ t and keratoconjunctiva staining scores of the two groups had statistically significant difference.The total effective rate of 0.05％ CsA treatment group was 75％ (15/20) and vehicle group was 25％ (5/20).There was a statistically significant difference between groups (P =0.000),and the 95％ confidence interval (C1) of the difference value of total effectiveness between the two groups was 30.80％-53.75％.At the end of this trial,there was no statistically significant difference in visual acuity distribution (P =0.890).No obvious discomfort was found in the patients received 0.05％ CsA eye drops.There were no adverse events during the follow-up duration.Conclusions 0.05％ CsA ophthalmic emulsion is an effective and safe treatment for dry eyes.

Hydrophidae, one of the precious traditional Chinese medicines, is generally drily preserved to prevent corruption, but it is hard to identify the species of Hydrophidae through the appearance because of the change due to the drying process. The identification through analysis on gene barcode, a new technique in species identification, can avoid the problem. The gene barcodes of the 6 species of Hydrophidae like Lapemis hardwickii were aquired through DNA extraction and gene sequencing. These barcodes were then in sequence alignment and test the identification efficency by BLAST. Our results revealed that the barcode sequences performed high identification efficiency, and had obvious difference between intra- and inter-species. These all indicated that Cyt b DNA barcoding can confirm the Hydrophidae identification.
