OBJECTIVETo study the effect of Compound Ezhu Powder (CEP) on serum levels of CA125 and CA19-9, and the expression of cyclin D protein in endometriosis patients, thus providing theoretical evidence for clinical application of CEP.

METHODSTotally 69 all endometriosis patients underwent surgical treatment at Department of Gynecology and Obstetrics, Tianjin Nankai Hospital from January 2011 to January 2013 were randomly assigned to group A (35 cases) and group B (34 cases). Meanwhile, 30 patients with uterine fibroids who prepared for surgical treatment during the same period were recruited as the control group. Patients in group A took EZP 3 months before surgery. No treatment was given to patients in group B and the control group. The serum CA125 level and the expression of cyclin D in the ectopic endometrium and the eutopic endometrium were detected in the 3 groups before surgery.

RESULTSThe expression of cyclin D was higher in group A and group B than in the control group (P < 0.05). The serum levels of CA125 and CA19-9 were significantly lower in group A than in group B (P < 0.05). The expression of cyclin D in the ectopic endometrium was lower in group A than in group B, but with no statistical difference (P > 0.05). The expression of cyclin D in the eutopic endometrium was significantly lower in group A than in group B with statistical difference (P < 0.05). Meanwhile, the serum CA125 level was positively correlated with the serum CA19-9 level (r = 0.45, P < 0.05).

CONCLUSIONSThe expression of cyclin D obviously increased in endometriosis patients, which was associated with the occurrence of endometriosis. CEP could lower serum levels of CA125 and CA19-9, and down-regulate the expression level of cyclin D, indicating its roles in inhibiting the cell cycle.

Objective To evaluate the damage to the brochial plexus produced by pulsed radiofrequency (PRF)and radiofrequency thermocoagulation(RFTC).Methods Fifty-five male Wistar rats weighing 250-300 g were randomly divided into 3 groups:groupⅠPRF(n=25):groupⅡRFTC(n=25)and groupⅢnormal control(n=5).The animals were anesthetized with intraperitoneal chloral hydrate.The left brochial plexus was exposed and PRF or RFTC was applied to the left brochial plexus.The voltage and current of the minimal stimulation which elecited muscle twitching and the impedance before and after operation were recorded in group PRF and RFTC.The nerve function was scored according to Tarloo(0=flaccid paresis,5=normal gait)before and at 3d after operation.The animals were killed and the left brachial plexus was removed immediately and at 1, 7,14,30 d after operation(n=5 at each time point)for determination of histopathological changes using microscope.Results The impedance and Tarlov score were significantly decreased after operation as compared to the baseline values before operation in group RFTC and were also significantly lower than in group PRF. Microscopic examination showed that the myelinated nerve fibers exhibited Wallerian degeneration and axon regeneration and the cytochondria in cylindraxile were severely injured or disappeared in group RFTC.The myelinated nerve fibers and the cytochondria in cylindraxile were significantly less injured after operation in group PRF than in group RFTC and returned to normal at 7 d and 30 d respectively.Conclusion The injury to brachial plexus produced by PRF is slighter than that produced by RFTC.

Objective To evaluate the value of double stapling technique with curved cutter stapler in colorectal anastomosis,especially in low colorectal anastomosis. Methods The clinical data of 168 cases of rectal carcinomas treated with double stapling technique with curved cutter stapler were retrospectively reviewed.The intraoperative condition,postoperative complications and findings during follow up were analysed. Results During the operations,the processes of closure and anastomosis of all the patients were satisfactory,and no operative death occurred.After the operations,4 cases(2.4%) had anastomotic leakage,3 cases(1.8%) had anastomotic bleeding,and 2 cases(1.2%) had rectovaginal fistula.All the complications were cured.There was no anastomotic stricture. Conclusion Double stapling technique with curved cutter stapler may help to accomplish low colorectal anastomosis which is a difficult task for handed suture.

· AIM: To discuss the cause and management of complications during the manual small incision cataract surgery (MSICS).combined with intraocular lens implant (MSICS-IOL) were done in 160 patietns with cataract. In this paper, we reviewed the clinical data of the intraoperative complications.injury, posterior capsule rupture, iris prolapse and hyphema, were mainly caused by inexpert skill and lacking of experience.techniques, careful operation could decrease the incidence of complications during MSICS operation. By proper management, the intraoperative complications could be solved satisfactorily.

OBJECTIVETo explore the effect of Jingui Shenqi pill (JGSQP) with various concentrations at different time points on pituitary adrencorticotropic hormone (ACTH) gene expression level in Shen-Yang deficiency rats.

METHODSThe Shen-Yang deficiency rats were randomly divided into the model control group and the high, medium and low dosage of JGSQP groups. Reverse transcriptase polymerase chain reaction was used to observe the effect of JGSQP on the ACTH mRNA of pituitary tissue in rats treated at different time points (10 d, 20 d, 30 d).

RESULTSAs compared with that in the model group, the ACTH gene expression level was significantly higher in the high dose JGSQP group (P < 0.05), and the increment in the medium dosage group was significantly higher in comparing with that in the high and low dosage groups (P < 0.05 or P < 0.01).

CONCLUSIONThrough up-regulation on ACTH gene expression is possibly one of the mechanisms of JGSQP in treating Shen-Yang deficiency.

OBJECTIVETo observe the impact of bone morphogenetic protein-2 (rhBMP-2) on bone marrow stromal cells (BMSCs) osteogenesis in vitro and vascular endothelial growth factors (VEGF) expression in bone osteoporotic to prevent and treat the osteoporosis.

METHODSTwenty 6-month-old female SD rats weighted (300±20) g underwent bilateral ovariectomized. At 3 months after operation, dual-energy X-ray absorptiometry was used to measure bone mineral density of rats,the values were compared with preoperative to ensure the model successfully, and the osteoporosis rats' BMSCs were cultured by bone marrow adherent cultured and the BMSCs morphology was observed under a phase contrast microscope upside down. The osteoporosis rats' BMSCs at the 2nd generation (p2) were randomly divided into experimental and control groups and were added complete medium (containing rhBMP-2) and osteogenic induced liquid, respectively. Two weeks later, the formation of cell calcium nodules were detected by Alizarin red staining method,alkaline phosphatase activity was measured by enzyme standard instrument and the expression of VEGF was detected by RT-PCT method.

RESULTS(1)Whole body bone mineral density of rats before and after operation were (0.179±0.007), (0.158±0.006) g/cm2,there was statistically significant (t=4.180,P< 0.05). (2)Alizarin red staining at 2 weeks after osteogenesis induced by BMSCs (P2) in the experimental group had more strong dyeing effect than the control group obviously. (3)Alkaline phosphatase activity at 2 weeks after osteogenesis induced by BMSCs (P2) of the experimental group (15.62±1.27) ug/gprot was significantly higher than that of the control group (8.62±0.93) ug/gprot,there was statistically significant (t=7.709, P<0.01). (4)The expression of VEGF at 2 weeks after osteogenesis induced by BMSCs (P2) of the experimental group 3.723±0.143 was significantly higher than that of the control group 0.950±0.072, there was statistically significant (t=29.462, P<0.01).

CONCLUSIONRhBMP-2 can improve the in-vitro osteogenesis ability of ovary osteoporosis rat BMSCs, promote the VEGF expression of osteogenesis factor. Regulating the VEGF expression may be one of the mechanisms of BMP-2 to participate in bone metabolism.
