Objective To observe the impact of different surgical procedures on ovarian reserve and analge-sic effects of drug use in patients with uterine fibroids.Methods 100 patients with uterine fibroids were randomly divided into two groups.50 patients in control group were implemented traditional open surgery.50 cases in the obser-vation group received laparoscopic myomectomy.The ovarian reserve changes were compared before and after surgery, pain medication use and changes in the degree of pain conditions.Results The levels of follicle stimulating hormone and luteinizing in the control group one,three months after operation were significantly higher than before surgery and the observation group,the level of estrogen was significantly lower than before surgery and observation group,the differences were statistically significant(t=10.23,14.58,9.78,11.76,9.83,9.92,10.07,11.23,all P<0.05).The postoperative first pain time of the observation group was significantly longer than the control group,the difference was statistically significant[(513.74 ±284.52)min vs.(61.38 ±37.21)min,t=92.34,P<0.05].The postoperative analgesic usage of the observation group was significantly lower than the control group,the difference was statistically significant(14.0% vs.58.0%,χ2 =7.83,P<0.05).The pain scores 3d,4d,5d,6d and 7d after operation of the observation group were significantly lower than the control group(t=2.11,2.30,2.58,7.03,6.46,all P<0.05). Conclusion The patients with uterine fibroids laparoscopic myomectomy for treatment will not cause great impact on the patients'ovarian reserve,and can effectively reduce the use of analgesics,and it is worthy of further promotion.

AIM:To investigate the effect of NF-κB binding element deletion on transcriptional regulation of (NOX1).METHODS:pGL3-Basic vector inserted with the NOX1 proximal promoter, and the same vector inserted with the NOX1 proximal promoter in the absence of the positive NF-κB binding element, were constructed.After cloning, diges-tion and purification, NOX1 proximal promoter (≈1 415 bp) was inserted into the multicloning site of the pGL3-Basic vec-tor and then sequenced ( pGL3-NOX1-1415) .NF-κB binding elements in the NOX1 promoters were predicted by Alibaba 2.1 software.The positive element was deleted by overlapping PCR.The deletion mutant was inserted into the pGL3 vector in the same way (pGL3-NOX1-1327).The plasmids were transfected into A549 cells, and then the cells were stimulated with TNF-α.The luciferase activity was monitored on MD SpectraMax M5 enzyme-labeled instrument.RESULTS:The se-quences of pGL3-NOX1-1415 and pGL3-NOX1-1327 were identified to be correct.Compared with control group, the lucif-erase activity was significantly higher in the cells transfected with pGL3-NOX1-1327 (P<0.05), but it was significantly lower than that in the cells transfected with pGL3-NOX1-1415 (P<0.05).CONCLUSION: NF-κB plays an essential role in the transcriptional regulation of NOX1 in TNF-α-induced A549 cells.Activated NF-κB binds to specific elements in NOX1 promoter regions to control the transcription.

Objective To explore the correlation between executive function and white matter lesions (WML) and the diagnostic value by clock drawing test(CDT) in patients with vascular dementia (VaD). Methods Twenty-seven VaD patients and twenty-five normal control subjects were evaluated with CDT to assess the executive function. CDT was scored according the four point method. Age-related white matter change rating scale (ARWMCrs) was used qualitatively to measure and locate the WML by cranial MRI scanning. Results 1. The scores of CDT in normal cognition health and VaD were ( 3.88 ± 0. 33 ) and ( 1.74 ± 0. 98 ). The difference between two groups was statistically significant (P＜0. 01 ). The humerous part and the point part were the earliest to decline in the VaD Patients. The scores of WML were (5.12 ± 4. 19) and ( 11.19± 3.09), respectively. There was significant difference between two groups(P ＜ 0. 01 ). The scores of CDT had significant positive correlation with MMSE scores and negative correlation with WML scores (P ＜ 0. 01 ). Conclusion The executive functional impairment in patients with VaD could be associated with the degree of WML.

OBJECTIVE:To observe the effects of different regimens of tranexamic acid on perioperative bleeding and postoper-ative compliance of simultaneous bilateral total knee arthroplasty(TKA). METHODS:A total of 70 patients undergoing simultane-ous bilateral TKA in our hospital were randomly divided into control group and observation group,with 35 cases in each group. Control group was given Tranexamic acid injection 15 mg/kg 30 min before surgery. Observation group was given Tranexamic acid injection 15 mg/kg,30 min before surgery and 30 min before suturing incision. The operation duration,total blood loss,intraopera-tive blood loss,postoperative drainage as well as the levels of FIB,PT,APTT before trectment and 3 d after surgery,the occur-rence of postoperative compliance and ADR were observed and compared between 2 groups. RESULTS:There was no statistical significance in operation duration,intraoperative blood loss and rate of ADR between 2 groups (P>0.05). The total blood loss, postoperative drainage and the incidence of complications of observation group were significantly lower than those of control group,with statistical significance(P<0.05). There was no statistical significance in coagulation indexes(FIB,PT and APTT)be-tween 2 groups before treatment and 3 d after surgery,with statistical significance(P>0.05). CONCLUSIONS:The application of tranexamic acid 30 min before simultaneous bilateral TKA and 30 min before the end of surgery can reduce perioperative bleeding and postoperative venous thromboembolism with good safety.
