Objective To investigate serum levels of β-human chorionic gonadotrophin (β-HCG) and progesterone (P) in early pregnant women,and their relation to luteal maintenance therapy for early pregnancy protection.Methods One hundred and thirty five infertility women treated in Department of Gynecology and Obstetrics of Beijing Chaoyang Hospital from January 2007 to December 2011.Total 150pregnancy cycles,including 84 with intrauterine insemination (IUI) and 66 with natural conception,were divided into two groups:normal intrauterine pregnancy group (group A,n =80) and early pregnancy loss group (group B,n =70).Medical history,ultrasonic findings,serum female hormone,P and β-HCG levels at early pregnancy stage were analyzed.Results The age of group A and group B was (30.0 ± 3.9) years and(30.7 ± 4.9) years,respectively (P ＞ 0.05).The follicle-stimulating hormone/luteinizing hormone in group A and group B was 1.57 ±0.96 and 1.56 ± 1.08 ; the estradiol levels in two groups were (152 ±66) pmol/L and (147 ± 69) pmol/L,respectively (both P ＞ 0.05).There were no differences in dominant follicles and endometrial thickness between groups A and B (P ＞ 0.05).Ovulation promotion and luteal support treatments were adopted in both groups:50％ (40/80) of cycles in group A received ovulation promotion,73％ (58/80) of cycles received luteal support,while 44％ (31/70) and 76％ (53/70) received in groups B,respectively.The levels of serum progesterone in group A during 14-21 d,22-27 d and ≥ 28 d after ovulation were higher than those in group B at each time points (P ＜ 0.0l).There were no significant differences in serum progesterone levels between women with luteal support treatment and those without luteal support treatment in both groups (P ＞ 0.05).Conclusion Dynamic monitoring of serum progesterone level in early pregnancy may be used as an auxiliary index for prediction of pregnancy outcome,but it may not be an indicator for luteal maintenance therapy.

The affinity and specificity of scFv were evaluated by ELISA and immunohistochemistry. Results ScFv-core DNA digestion and sequence data showed that the scFv gene was composed of 774bp. Conclusion Human single chain Fv antibody against HCV core antigen has a specific combining capacity with hepatitis C virus core antigen.

Objective: To develop a sensitive and rapid liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) method for the simultaneous determination of wogonin, coptisine, berberine, palmatine, jatrorrhizine, phellodendrine, magnoflorine, and wogonoside in rat plasma and to evaluate the pharmacokinetic characteristics of Huanglian Jiedu Decoction (HJD). Methods: LC separation was performed on an Acquity HSS T3 column (100 mm × 2.1 mm, 1.8 μm) using gradient elution with the mobile phase consisting of acetonitrile and 0.1% formic acid water. The detection was accomplished by using positive electrospray ionization in multiple-reaction monitoring mode. Plasma samples were pretreated by protein precipitation. Results: The method showed a good linearity over a wide concentration range (r2 > 0.99). The lower limits of quantification were 0.20 ng/mL for coptisine and phellodendrine, 0.48 ng/mL for berberine, 0.10 ng/mL for jatrorrhizine, 0.32 ng/mL for magnoflorine, 0.30 ng/mL for palmatine, and 4.80 ng/mL for wogonin and wogonoside, respectively. The intra- and inter-day precision of the analytes was less than 12.11%, while the accuracy was between -14.46% and 4.86%. The mean recovery of all the analytes ranged from 93.10% to 110.91%. Conclusion: This validated method offers the advantages of high sensitivity. It is successfully applied to evaluating the pharmacokinetic properties of HJD. © 2014 Tianjin Press of Chinese Herbal Medicines.

Objective Toexploretheclinicalefficacyandtoxicityofintensitymodulatedradiationtherapy(IMRT)combined with high intensity focused ultrasound(HIFU) for inoperatable recurrent hepatic carcinoma after operation and TACE .Methods Total 60 patients with inoperatable recurrent hepatic carcinoma after operation and TACE were randomly divided into two group ,30 patients in observation group received IMRT and HIFU ,while 30 patients in control group received only IMRT .For both groups , the same radiotherapy technic was given with IMRT in 6 MV X‐ray ,the total dose was 54 -70 Gy/6 -7 weeks .In observation group ,HIFU was carried out concurrently with IMRT (5 days/week ,6-7 weeks) .Results The difference of the short‐term effi‐cacy between the observation group and the control group was statistically significant (P<0 .05) ,there was no significant difference in acute radioactive toxicity between the two groups (P>0 .05) .The one and two year overall survival rate 89 .9% ,78 .9% in obser‐vation group ,while 72 .8% ,36 .2% in control group ,the differnces were statistically significant (P<0 .05);the one and two year progression‐free survival rate were 85 .9% and 50 .9% in observation group ,while 64 .3% and 28 .1% in control group ,the differ‐ences between two groups were statistically significant (P<0 .05) .The medium survival time was 36 months in observation group , and 24 months in control group;the medium progression‐free survival was 27 months in observation group ,and 17 months in control group .Conclusion For recurrent unresectable or reject surgery after TACE in patients with primary hepatic carcinoma ,the efficacy of IMRT combined with HIFU treatment is effective ,the toxicity can be tolerated ,and has certain application value .

The nuclear transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) plays a crucial role in maintaining cellular redox homeostasis. The aberrant NRF2 signaling confers enhanced antioxidant capacity, which is linked to tumor progression and therapeutic resistance. The current study investigates the biological effects and molecular mechanism of tribbles homolog 3 (TRIB3), a stress-induced protein, in regulating cell survival and apoptosis in lung cancer. This study first performed the RNA sequencing data analysis with 576 lung adenocarcinoma patients from the cancer genome atlas (TCGA) database. The NRF2- antioxidant response element (ARE) signature was enriched in patients with high TRIB3 expression. Dual-luciferase reporter assay and real-time quantitative polymerase chain reaction (PCR) were used to confirm the effect of TRIB3 on the kelch-like ECH-associated protein-1 (KEAP1)-NRF2 pathway. Abrogation of TRIB3 impaired NRF2 transcriptional activity and reduced the expression of its target genes. Moreover, TRIB3 enhanced NRF2 stability via blocking KEAP1-NRF2 interaction. TRIB3-depletion promoted reactive oxygen species (ROS) production, restrained cell proliferation, and enhanced carboplatin-induced apoptosis. In addition, NRF2 overexpression recovered the tumor inhibition effect of TRIB3-depletion. Consistently, TRIB3 failed to modulate apoptosis in NRF2 depletion cells. In summary, this study shows that TRIB3 inhibits the KEAP1-NRF2 interaction and upregulates the transcriptional activity of NRF2, thereby promoting lung cancer cell proliferation and reducing the sensitivity to chemotherapy. Targeting the TRIB3-NRF2 signal axis may become a new strategy for ROS homeostasis and lung cancer treatment.

As one of the first resident standardized training bases, department of ophthalmology of Shanghai Ruijin Hospital participated in this reform process from 2010. Relevant rules and regulations (training management system , training scheme implementation system and evaluation system ) were strictly obeyed. When new problems emerged, under the guidance of department in charge, a series of regimens were formulated and improved gradually by Ophthalmology Professional Committee of Shanghai Resident Standardized Training Department. Based on reviewing and summarizing the work in the last 3 years, some thoughts and suggestions on the resident standardized training in future were put forward ,in-cluding how to better solve the“heavily used, lightly cultured” problem, the“disregarding medical ethics establishment”problem, the“disregarding assessment of teachers”problem and the“disregard-ing obtaining employment”problem.
