Objective To estimate the expression of ER and PR in the endometrium of both intrauterine adhesions (IUA) and non-IUA specimens. Methods The endometrium specimens from patients undergoing hysteroscopy for confirmed moderate IUA (n=20: 10 in proliferative phase, and 10 in secretory phase) were enrolled as the IUA group in Beijing Obstetrics and Gynecology Hospital from October 2014 to August 2015. The specimens scheduled for hysteroscopy due to infertility were recruited into the control group (n=26: 13 in proliferative phase, and 13 in secretory phase). Immunohistochemistry and quantificational real-time PCR (qRT-PCR) were used to detect the expression of ER-α, ER-β and PR in endometrium with different menstrual period in both groups. Results (1) Location: in both groups, the expression of ER-α, ER-β and PR appeared in the endometrial glandular epithelial cells and the stromal cells of the endometrium. The positive brown granules of ER-α, ER-β and PR appeared mainly in cell nucleus. (2) ER-α and ER-β in the endometrium:the protein expression of ER-α and ER-β in IUA group (proliferative phase: 0.657 ± 0.028, 0.493 ± 0.023; secretory phase: 0.537 ± 0.020, 0.365 ± 0.031) were significantly higher than those of control group (proliferative phase: 0.586 ± 0.025, 0.437 ± 0.022; secretory phase:0.459 ± 0.025, 0.323 ± 0.017;all P<0.01). And the ER-αand ER-βmRNA expressions in IUA group were 2.524 ± 0.296, 1.947 ± 0.339, higher than those of control group in the proliferative phase (all P<0.01), and in the secretory phase (1.977±0.333, 1.345±0.292) were also higher than those in the control group (all P<0.01). (3) PR in the endometrium: the protein expression of PR was not significantly different between IUA group (proliferative phase:0.248±0.025, secretory phase:0.194±0.024) and control group (proliferative phase: 0.234 ± 0.019, secretory phase: 0.186 ± 0.020; P=0.162, 0.359). Meanwhile, there were no statistical differences in the mRNA expression of PR in both groups with different menstrual period (proliferative phase: 1.144 ± 0.384 versus 0.981 ± 0.306, secretory phase: 0.763 ± 0.237 versus 0.631 ± 0.203; P=0.270, 0.166). (4) ER and PR expression in menstrual cycles: the expression of ER-α, ER-β and PR in the IUA group changed with the menstrual cycles, and their expression in the proliferative phase were higher than those in the secretory phase (all P<0.05). Conclusions The expression of ER-α and ER-β in the endometrium of IUA patients changes with menstrual cycle, and are higher compared with those in normal endometrium. No difference is found in the PR expression between the two groups.

Objective: To identify corticotropin releasing hormone(CRH) positive cells from the human placenta. Methods: Using immunohistochemistry to show the cellular expression of placental CRH. Results: During human pregnancy, placental CRH level rose markedly from undetectable amounts prior to 20 weeks gestation to nearly the peak level. Conclusion: The presence of CRH in maternal plasma is attributed to the placental production and subsequent release of this hormone into the maternal circulation. [

In this study, ITS2 barcode was used to identify Bupleurum chinense and B. longiradiatum. The ITS2 regions of 48 samples were amplified and sequenced. The sequences obtained above were aligned and the K2P distances were calculated. We used three methods, BLAST1, nearest distance and phylogenetic tree (NJ-tree), to test the identification ability. The results showed that the maximum intraspecific genetic distance of B. chinense was 0.013, and the minimum interspecific genetic distance between B. chinense and B. longiradiatum was 0.049. The NJ-tree can easily identify B. chinense and B. longiradiatum. Therefore, the ITS2 barcode is suitable to identify B. chinense and B. longiradiatum.

Background Neovascular glaucoma is a type of refractory glaucoma.Biological amnion combined with glaucoma valve implantation is a primary therapy and its long-term effectiveness is noticeable. Objective The goal of this Survey was to evaluate the effectiveness of biological amnion combined with glaucoma valve implantation for neovascular glaucoma and compare the clinical outcome with simple glaucoma valve implantation. Methods This was a retrospective observational case series.The clinical data of 44 eyes of 44 patients received biological amnion combined with glaucoma valve implantation for neovascular glaucoma and 43 eyes of 43 patients received simple glaucoma valve implantation for neovascular glaucoma were retrospectively analyzed and compared.The age,sex and disease-cause were matched between these two groups.Patients were followed-up for 24 months after operation.Surgery success was identified as the intraocular pressure(IOP)<21 mmHg after operation.Written informed consent was obtained from each patient prior to the operation.Results The IOP was<21 mmHg throughout the follow-up duration in both groups.No significant difierence was found in the IOP value in 1 week after operation between two groups(t=-5.34,P=0.60).However,IOP values were lower in biological amnion combined with glaucoma valve implantation group in 3,12 and 24 months after operation than those of simple glaucoma valve implantation(t=6.64,t=5.00,t=7.81,P<0.01).Operation successful rates in biological amnion combined with glaucoma valve implantation group were 97.73％.93.18％。90.24％and 82.05％in 1 week,3 months,12 months and 24 months respectively after operation.and those in simple glaucoma valve implantation were 95.35％,71.43％,65.00％and 60.53％in corresponding time points,showing considerably significant differences between two groups (χ2=7.06,χ2=7.47,χ2=4.37,P<0.05).There was no significant difference in Ihe number of eyes with complication between the two groups(P>0.05). Conclusion The biological amnion combined with glaucoma valve implantation surgery may be more effective and safe for the treatment of neovascular glaucoma than with glaucoma va]ve only.

·AIM: To study the expressive variation of Nogo-A on rat retina in the process of chronic ocular hypertension. · METHODS: Thirty-six healthy adult male Wistars were randomly divided into control group (6 rats) and chronic hypertension group (30 rats). Chronic hypertension was created by cauterizing the superficial scleral veins. Immunohistochemistry technique was used to evaluate the expressive varieties of Nogo-A at different time points during the course of chronic ocular hypertension. · RESULTS: The success of the model was indicated by over 40% of increase in the IOP as compared with normal rats. Compared with control group, as time passed chronic hypertension group gradually had detectable morphology changes in the retina. At the 21st day of chronic ocular hypertension, retinas became thinner and the quantity of retinal ganglion cell (RGC) decreased (P<0.05). Assoicated with the morphological changes, the expression of Nogo-A was strongly increased (P<0.05).CONCLUSION: Myelin associated protein Nogo-A plays a part in the process of chronic ocular hypertension.

AIM: To study the effects of geranylgeranylacetone(GGA) on the expression of heat shock protein70(HSP70) on retinal ganglion cells(RGC) in rats with chronic intraocular pressure(IOP) elevation.METHODS: Seventy Wistars were divided into blank control group(10 rats), chronic hypertension group(30 rats) and GGA group(30 rats). Chronic hypertension was created by cauterizing the superficial scleral veins. 800mg/(kg·d)GGA was given by oral daily after cauterization. Immunohistochemistry was used respectively to observe the changes of expression of HSP70 in the model rats and GGA interference rats at different time points during the course of chronic IOP elevation.RESULTS: The successful model was identified as the IOP over 40% of normal rats. The retinal thickness was significantly reduced in model group and model+ GGA group compared with normal rats from 21 days through 28 days after cauterization(P<0.05), and that of model rats was obviously decreased in comparison with model+ GGA rats(P<0.05). The number of ganglion cells was significantly decreased in model rats and model+ GGA rats compared with normal rats from 21 days and 28 days. The stronger expression intensity(IOD) value was seen for HSP70 in the model+ GGA rats by immunochemistry(P<0.01).CONCLUSION: Systemic administration of GGA protects retina from chronic IOP elevation by regulating the expression of HSP70.

BACKGROUND: In animal experiments, ultrasound-mediated microbubbles can promote the homing of transplanted stem cells to the ischemic area, enhance angiogenesis and small arterial formation, improve local blood flow in the ischemic myocardium and restore myocardial contractility.OBJECTIVE: To investigate the effect of ultrasound-mediated microbubbles on intravenously transplanted bone marrow mesenchymal stem cell (BMSC) homing and the therapeutic efficiency on ischemic stroke. METHODS: A middle cerebral artery occlusion (MCAO) model was induced by plug wire preparation. At 72 hours after MCAO, model rats were randomized into four groups: PBS group (n=15), BMSCs group (n=18), ultrasound+BMSCs group (n=18), ultrasound+microbubble+BMSCs group (n=18). Corresponding treatment was done in each group: 2 mL of PBS was injected via tail vein in the PBS group; about 3×106 BMSCs diluted by 2 mL of PBS were injected via tail vein slowly in the BMSCs group; after skull ultrasound radiation (1 MHz, 2 W/cm2) for 120 seconds, BMSCs were injected via tail vein slowly in the ultrasound+BMSCs group; the same process as the ultrasound+BMSCs group was done following intravenous injection of 0.1 mL/kg microbubbles in the ultrasound+microbubble+BMSCs group.RESULTS AND CONCLUSION: (1) Forty-eight hours after BMSCs transplantation, the BMSCs homing rate in the brain was significantly higher in the ultrasound+microbubble+BMSCs group than the other two groups (P < 0.05). (2) Twenty-eight days after MCAO, nerve damage was significantly milder in the ultrasound+microbubble+BMSCs group than the other two groups (P < 0.05). (3) Seven days after transplantation, the water content in the brain tissue was significantly lower in the ultrasound+microbubble+BMSCs group than the other two groups (P < 0.05). (4) Seven days after transplantation, the cerebral infarction volume was significantly reduced in the ultrasound+microbubble+BMSCs group compared with the other two groups (P < 0.05). To conclude, ultrasound-mediated microbubbles can enhance the homing effect of intravenously transplanted BMSCs, reduce cerebral edema and cerebral infarction volume, improve the neurological function, and increase the therapeutic effect of BMSCs transplantation on ischemic stroke.
