Objective To observe the efficacy of melbine combined with clomifene citrate in treatment of patients with polycystic ovarian syndrome ( PCOS) .Methods 60 patients aged 20 to 39 with PCOS were randomly divided into observation group and control group, 30 patients in each group.In the menstrual cycle of 3~7 d, the control group received clomifene citrate orally (50 mg per time, qd), and the observation group received melbine (2.5 mg per time, qd)combined with clomifene citrate (50 mg per time, qd), with a course of 5 days.Results The number of mature follicles and score of cervical mucus in obsercation group was significant higher than that in control group, respectively(P<0.05).The rate of follicular development and ovulation rate of single follicle in obsercation group was significant higher than that in control group, respectively(P<0.05), but there were no significant differences of pregnancy rate, first trimester abortion rate and periodic ovulation rate between two groups.The rate of endometrial thickness<7 mm patients in observation group was significantly lower and positive rate of three line was higher than that in control group, respectively ( P<0.05).The follicle stimulating hormone level in observation group was significantly lower than that in control group(P<0.05), but there was no significant difference of luteinizing hormone between two groups.Conclusion Melbine combined with clomifene citrate has a good effect on mature follicles number and endometrial thickness in anovulatory infertility women caused by polycystic ovary syndrome.

Objective To study the similarities and differences of information needs between cancer patients treated with radiotherapy and chemotherapy, analyze the causes for cancer patients' different choices, and provide reasonable and disease-related information for cancer patients. Methods A total of 102 and 119 cancer patients treated with radiotherapy and chemotherapy relatively were asked to complete the questionnaire (IPQCP+2) and two questions about the total information capacity and content requirements. Results Two groups had different needs of therapeutic information and treatment in IPQCP. Cancer patients treated with chemotherapy needed more widely-ranged information than patients underwent radio-therapy. Conclusions Most of cancer patients treated with radiotherapy and chemotherapy need to be informed of disease-related information, among which the content of therapeutic information and total information is relative to the treatment. Nurses should provide disease-related medical information based on their different needs, as to improve the life quality of cancer patients.

Objective To study the relationship between the T helper cells (Th22)/interleukin (IL)-22 and rheumatoid arthritis (RA) with interstitial lung disease (ILD), and to define the clinical significance of Th22 cells for RA. Methods The quantity of Th22 cells in the peripheral blood from 40 patients with RA (20 RA with ILD, 20 RA without ILD) were examined by flow cytometry, the level of IL-22 in the sera was detected by enzyme-linked immunosorbent assay (ELISA). Comparisons between groups were analyzed by t-test, rank sum test, and the correlation of parameters were tested by linear correlation analysis. Results The quantities of CD4+IL-22+ cells (Th22) in RA patients [(0.15 ±0.07)%] were significantly higher than normal controls [(0.09 ±0.05)%] (t=4.097, P<0.01), and IL-22 levels in RA patients [(83 ±7) ng/L] were significantly higher than normal controls [(61±5) ng/L] (t=13.057, P<0.01). The quantities of Th22 cells in RA-ILD patients [(0.18±0.07)%] were significantly higher than RA-NILD patients [(0.13±0.05)%] (t=2.919, P=0.008), and IL-22 levels in RA-ILD patients [(87±6) ng/L] were significantly higher than RA-NILD patients [(80±6)ng/L] (t=3.624, P=0.001). The quantities of Th22 cells were positively correlated with erythrocyte sedimentation rate (ESR), rheumatoid factor(RF) and 1.4 disease activity score (DAS)28 (r=0.336, 0.377, 0.577, P<0.05),and the level of IL-22 were also positively correlated with ESR and DAS28 (r=0.406, 0.576, P<0.05). Conclusion The quantities of Th22 cells and IL-22 level are increased in RA patients, especially in RA-ILD patients. The quantities of Th22 cells and IL-22 level are positively correlated with ESR and DAS28. It may play a certain role in RA especially in RA with ILD.

Objective:To investigate the reversing effect of recombinant mutant human tumor necrosis factor (rmh-TNF) on cisplatin(DDP)-resistant human ovarian cancer cell line SKOV3/DDP in vitro and the related mechanism. Methods: DDP-resistant human ovarian cancer cell line SKOV3/DDP was cultured in vitro. The cytotoxic effect of rmh-TNF to SKOV3/DDP cells was examined by MTT assay and the nontoxic dose of rmh-TNF was identified. The changes of DDP resistance was observed after cells were treated with nontoxic dose of rmh-TNF by MTT assay. The expre-ssion of GST-? protein was examined by flow cytometry at different periods after rmh-TNF intervention; RT-PCR was used to analyze the expression of MDR1gene in SKOV3/DDP cells before and after rmh-TNF treatment. Results:(1)rmh-TNF at 50-122.34 U/ml showed no evident inhibitory effect on the growth of SKOV3/DDP cells (the cell survival rate higher than 90%); and 100 U/ml was chosen for the reversing experiment ( nontoxic dose).(2)IC50 values of SKOV3/DDP cells were (23.29?0.43), (8.97?0.69) and (6.43?0.79) ?g/ml after treatment with DDP for 24, 48 and 72 h, respectively; and the values decreased to (19.50?0.50),(4.34?0.43) and (2.44?0.02)?g/ml after combined treatment with 100 U/ml rmh-TNF, respectively.(3)Expression of GST-? protein and MDR1gene decreased with the prolongation of rmh-TNF treatment. Conclusion: rmh-TNF has reversal effect on the DDP-resistant cell line SKOV3/DDP, and the mechanism may be associated with the down-regulation of GST-? protein and MDR1gene expression.

A method based on stable isotope dilution gas chromatography-mass spectrometry ( GC-MS ) was established to determine five kinds of organophosphate esters ( OPEs ) in different kinds of cosmetics. For cream and wax-based cosmetics, samples were extracted by appropriate solvent, and then purified by ENVI-Carb solid phase extracting column. For powder and aqueous samples, GC-MS test could be operated directly after solvent extraction and concentration. All of the samples were separated by DB-5MS (30 m×0. 25 mm× 0. 25 μm) chromatographic column, and detected by selected ion monitoring ( SIM ) mode. The target analytes were qualitatively confirmed by retention time and abundance ratio of characteristic ions, and quantified by stable isotope diluted internal standard method. Under the optimized conditions, the linear coefficients of the OPEs were larger than 0. 9995, the detection limits were 1. 0-30 μg/kg, the average recoveries ( n=6 ) ranged from 89 . 5% to 105%, and the RSDs were in the range of 2 . 9%-9 . 1%. The developed method, which was characteristic by satisfactory purification effect, favorable matrix effect elimination capacity, as well as high recovery, was suitable for the determination of OPEs in different kinds of cosmetic matrices.

Objective To evaluate the value of contrast-enhanced ultrasound in superficial lymphadenopathy. Methods Ninty-four superficial enlarged lymph nodes were studied by 2-dimensional, color Doppler ultrasound, and contrast-enhanced ultrasound. Then the contrast-enhanced images were analyzed by Philips Q-LAB software. All the results were compared with pathological diagnosis. Results For the 94 superficial lymph nodes examined,44 were benign,33 were metastases and 17 were lymphomas. The sensitivity, specificity,and accuracy of contrast-enhanced images were 84% ,74% and 790//oo respectively. Contrast-enhanced ultrasound examination showed intense homogeneous enhancement in 39 of 44 benign lymph nodes; high or low homogeneous enhancement in 25 of 33 and 7 of 33 in metastases respectively;intense homogeneous, and scarce enhancement in 6 of 17 and 9 of 17 in lymphomas respectively. Time-intensity curves showed that compared with metastasis lymph nodes and lymphomas, benign lymph nodes had higher peak intensity and larger area under the curve (P<0.01). Conclusions The diagnosis accuracy was significant increased when contrast-enhanced ultrasound was test against conventional ultrasound. The character of contrast agent enhancement and Q-LAB time-intensity curves provide valuable diagnosis information for differential diagnosis of benign,metastasis lymph nodes and lymphomas.
