ABSTRACT
Objective To investigate the feasibility of a non-invasive sampling method by collecting menstrual blood and obtaining endometrium for further research in menstruation-related diseases.Methods On the second day of menstruation,menstrual blood was collected with menstrual cups for 4 hours,and the menstrual endometrium was filtered through a metal screen for weighing,cryopreserved,immunohistochemical staining and cell culture.Results The collection process was painless and non-invasive.In the control group,the menstrual volume was (9.1±0.7) ml,and the endometrial tissue weight was (91.0+ 14.7) g.In the endometriosis group,the menstrual volume was (9.6± 1.9) ml (P=0.022),and the endometrial tissue weight was (134.7±43.9) g (P=0.057).Endometrial cell culture was successful in all patients and should not be contaminated.The growth curve was a finite cell line type.The expression of cytokeratin 19 and vimentin in menstrual endometrium and cells were positive.Conclusions By collecting menstrual blood and filtering endometrial tissue,it is an ideal non-invasive sampling method.In combination with advanced experimental technology,menstrual endometrium make further researches of endometriosis,endometrial lesions or other menstruation-related diseases possible.
ABSTRACT
Objective To evaluate the impact of gonadotropin-releasing hormone agonist(GnRH-a) used before surgery on natural pregnancy rates in patients with ovarian endometriomas. Methods In this retrospective study, 57 patients with ovarian endometriomas who had a consecutive laparoscopic surgery between June, 2010 to September, 2015 in Peking Union Medical College Hospital were included. Those patients were divided into preoperative GnRH-a treatment group(n=31)and non-GnRH-a treatment group (n=26). There were no differences in patients'characteristics between the two groups. All of them had a desire for natural pregnancy postoperatively. GnRH-a was no longer used after surgery. After the surgical procedure, the patients were observed over a period of 12 months, during which the frequency of natural pregnancy was assessed. The two groups were compared in terms of natural pregnancy rates. Results Totally 33 patients had natural pregnancy after surgery. The univariate analysis showed that the pregnancy rates of age, r-AFS stage, infertility, preoperative use of GnRH-a, tumor size, tumor side, deep infiltrating endometriosis and adenomyosis did not have statistically significant differences (all P>0.05). The two classified logistic regression showed that OR for preoperative use of GnRH-a was 0.250(95％CI: 0.064-0.978)with a statistical difference(P=0.046). Conclusion The use of GnRH-a preoperatively may have a negative effect on natural pregnancy rates of patients after surgery with ovarian endometriomas.
ABSTRACT
Objective To investigate the clinical features, diagnosis and treatments of pelvic abscess with endometriosis. Methods A retrospective analysis was performed on 129 cases of pelvic abscess in Peking Union Medical College Hospital from January 2000 to January 2016. Among them, 34 women with endometriosis were divided into the study group and the others were in the control group. The clinical characteristics, therapeutic regimens and outcomes were compared. Results (1) General conditions:there were no statistic differences between the two groups in age, WBC, serum CA125, intrauterine device in use, pelvic inflammatory disease history;while incidence rates of dysmenorrhea (65%, 22/34) and infertility (21%, 7/34) in the study group were higher than those in the control group (all P<0.05). (2) Clinical manifestations:fever, abdominal pain and pelvic mass were the main symptoms in two groups. The incidence rates of septic shock were 12%(4/34) in the study group and 2%(2/95) in the control group (P<0.05). (3) Treatment:treatment with puncture all failed in the study group (7/7) and surgeries were required. In contrast, there was only 1/19 treatment failure with puncture in the control group. The puncture failure rates were statistically significant (P<0.05). Compared with the study group and the control group, there were significant differences (P<0.05) in the operation time of laparoscopic surgery [(76±41) versus (53±21) minutes] and of laparotomy [(168±58) versus (116±35) minutes], intra-operative blood loss of laparoscopic surgery [(216±296) versus (43±36) ml] and of laparotomy [(448 ± 431) versus (145 ± 24) ml]. Conclusions Pelvic abscess in women with endometriosis is more severe and refractory to antibiotics and puncture treatment. Active surgical intervention is required. Although surgical procedures are often difficult, prognosis is comparatively satisfied.
ABSTRACT
Objective To investigate the changes in serum matrix metalloproteinase(MMP)-2 and MMP-9 and their relationship with serum B-type brain natriuretic peptide(BNP)in patients with chronic heart failure.Methods MMP-2,MMP-9 and serum BNP levels were measured in 184 patients with chronic heart failure and 61 healthy controls.The relationship between changes in MMP-2 and-9 and serum BNP was analyzed.Results Chronic heart failure was categorized into grade Ⅱ,Ⅲ and Ⅳ according to NYHA.In grade Ⅱ,Ⅲ and Ⅳ and the control group,the levels of MMP-2 were(309.1±60.1)nmol/L,(422.6±89.6)nmol/L,(694.8±126.2)nmol/L and(217.2±26.3)nmol/L respectively,and the levels of MMP-9 were (321.2±63.2)nmol/L,(454.4±96.3)nmol/L,(634.1±51.2)nmol/L and(210.8±23.6)nmol/L respectively.The levels of MMP-2 and MMP-9 were significantly higher in chronic heart failure subgroups than in the control group(F=3.65,12.52;P=0.000,0.000).According to the pairwise comparison among the chronic heart failure subgroups,the levels of serum MMP-2 and MMP-9 were significantly higher in NYHA Ⅳ grade than in NYHA Ⅲ grade,and higher in NYHA Ⅲ grade than in NYHA Ⅱ grade(all P<0.05).In patients with chronic heart failure groups,MMP-2 was positively correlated with serum BNP(r=0.866,P=0.000),and with MMP-9(r=0.516,P=0.001).Conclusions MMP-2 and MMP-9 levels might be closely correlated with chronic heart failure and show an upward trend with the progression of chronic heart failure.The levels of MMP-2 and MMP-9 are associated with BNP,which indicates that clinical monitoring of the serum level changes can provide a certain reference for diagnosis,treatment and prognosis in patients with chronic heart failure.
ABSTRACT
Objective To investigate clinical outcomes of laparoendoscopic single-site ovarian cystectomy compared with traditional multi-port laparoscopic ovarian cystectomy. Methods Data of 81 patients with ovarian cystectomy from January 2016 to May 2017, the single-site group (n=40) and the multi-port group (n=41) in Peking Union Medical College Hospital were retrospectively collected. The outcomes of single-site and multi-port groups were analyzed and compared, including: postoperative fever, operation time, blood loss, hemoglobin change, surgical complications, postoperative pain score, postoperative analgesic requirements, body image scale and cosmetic score, length of hospital stay, postoperative total cost. Results No complication was found in two groups. No difference was found in postoperative fever, blood loss, hemoglobin change, postoperative pain score, length of hospital stay, and total cost between the two groups(all P>0.05).Operation time was(50±20)minutes in single-site group,and (40 ± 15) minutes in multi-port group; postoperative analgesic requirements was 28%(11/40) in single-site group,and 7%(4/41)in multi-port group;cosmetic score was 22.6±2.6 in single-site group,and 17.3±2.6 in multi-port group;body image scale was 5.7±1.2 in single-site group,and 6.2±1.2 in multi-port group;these four clinical parameters were statistical differences(all P<0.05).Conculsion Laparoendoscopic single-site ovarian cystectomy is feasible and safe,although it could′t relieve the postoperative pian,it do offer a higher cosmetic satisfaction.
ABSTRACT
Objective To investigate the abnormal expression of proto-oncogene YES-associated protein (YAP) in gastric cancer tissues in the elderly and its correlation with poor prognosis.Methods Clinical data of 80 elderly patients with gastric cancer treated in our hospital from March 2011 to October 2014 were statistically analyzed.Results The positive expression rate of YAP was significantly higher in gastric carcinoma than in adjacent tissues [71.3％ (57/80) vs.13.8％ (11/80),P＜0.05].The positive expression of YAP were significantly associated gastric tumor size,tumor stage,invasion depth and lymph node metastasis (all P＜0.05),but had no correlation with tumor differentiation (P＞0.05).The 5-year survival rate was significantly lower in patients with YAP-positive expression than in patients with YAP-negative expression (P ＜ 0.05),but the differences in 1-year,3-year survival rates were not significant between the two groups (all P＞0.05)The YAP expression,tumor stage,lymph node metastasis were significantly associated with the prognosis of gastric cancer in patients (all P＜0.05).Conclusions YAP-positive expression rate is significantly higher in gastric cancer tissues than in adjacent tissues in the elderly,which indicates poor prognosis of patients with gastric cancer.
ABSTRACT
Objective To explore the reproductive outcomes of different management strategies of ectopic pregnancy .Methods A retrospective cohort study was performed for 648 consecutive patients with a diagnosis of ectopic pregnaney between June 2011 and september 2013.The follow-ups were conducted telephone interviews of pregnancy outcomes after various treatments .Results The subsequent intrauterine pregnancy rates after surgical , medical and expectant managements were 89(65.0%), 35(79.6%) and 6 (54.5%) the intrauterine pregnancy was higher for medical treatment than that for surgical treatment (P<0.05).The subsequent infertility rate after surgical , medical and expectant management were 4.5%, 36.4%, 19.0%.The subsequent infertility rate after medical treatment was lower than that for surgical and expectant managament ( P<0.05) .The re-ectopic pregnancy rates of laproscopic versus abdominal operation were [11 (11.7%), 13(30.2%)] with significant difference (P<0.05).And abdominal operation was higher than laproscopic operation .Conclusion For younger ectopic pregnancy patients , medical treatment shold be as possible as we can .If operation is necessary , laproscopic operation is preferred .
ABSTRACT
Objective To investigate the risk of heart failure to the mother and the neonate.Methods The clinical data of 30 pregnant womem with heart failure from January 1993 to December 2010 from Capital Medical University Tongren Hospital was retrospectively analyzed.Results Of the 30 patients,there were 12 affected with congenital heart disease (40％) ; 9 with rheumatic heart disease 30％,7 with heart failure in pregnancy-induced hypertension 23％.Heart failure appeared at the average of (34.20 ± 4.25) weeks in pregnancy.The average terminal time of pregnancy was (34.84 ± 2.17) weeks.The rate of early birth was 73.33％.The average birth weight was (2011 ±568) g,with 7 babies less than 2000 g.No death occurred in both new the mother and the neonate.Condusion The main causes of heart failure in pregnancy are congenital and rheumatic heart disease and pregnancy-induced hypertension.For those heart failure occurs before 30 weeks,it is the first selection that pregnancy shoud be terminated; For those occur after 30 weeks,active treatment should be performed to improve maternal heart function and promote fetal maturity.Apropriate threatment during per-cesarean section may decrease the case fatality of the mother and neonate.
ABSTRACT
Objective To investigate strategies of diagnosis and treatment of ureter endometriosis. Methods From 1983 to 2010, the cases registered in Peking Union Medical College Hospital and confirmed as ureter endometriosis by surgery were enrolled in this study. Clinical manifestatios, preoperative examinations, surgical categories and routes, surgical and pathological findings, post-operative medical treatment, relapse and relating factors were collected and studied. Results Totally 46 patieuts with ureter endometriosis underwent one or two surgeries. Forty-eight per cent (22/46) of patients were not be diagnosed with ureter endometriosis pre-operatively, and 46% (21/46) only presented dysmenorrhea or even no symptoms. Ureterolysis (72%, 33/46) and laparotomy (63%, 29/46 ) were the most common surgical category and surgical approach. There were 64% (25/39) of patients had left ureter involved and 80% (37/46) had extrinsic ureter endometriosis. Fifteen per cent (7/46) of patients had relapsed disease with median recurrent time of 24 months (13 -49 months), and they all received second surgeries. Logistic regression analysis showed that only gonadotropin releasing hormone analogue agents were related with recurrence when compared with those patients without medical treatment post-operatively significantly ( OR =23.2, 95% CI:2. 4 -221.7, P =0. 002). Conclusions Ureter endometriosis was related with reproductive tract endometriosis. It has insidious process resulting in difficulty for early diagnosis. It's important to treat pelvic deep infiltrating endometriosis and ovarian endometrioma to prevent ureter from further involvement. Post-operative treatment of pelvic endometriosis is the key point of preventing relapse of ureter endometriosis.
ABSTRACT
Objective To summarize the common causes of fetal arrhythmia and explore its clinical significance and correlation with fetal prognosis. Methods The clinical situation and diagnostic procedure as well as the results of long-term follow-up of 26 cases of fetal arrthythmias were analyzed retrospectively. Results The incidence of fetal arrhythmias is 0.2%. 11.5%(3/26) of them were diagnosed fetal tachycardia, 15.4% (4/26) of them were diagnosed fetal bradycardia and 73.1% (19/26)were diagnosed irregular fetal cardiac rhythm . The average gestational age they were diagnosed was 35 +2 weeks (15 weeks to 41 +1weeks). Twenty-two cases were diagnosed by antenatal auscultation, 1 case was diagnosed by ultrasonography at 15 weeks' gestation, 3 cases were diagnosed by fetal heart monitoring. We performed fetal echocardiograms on 17 fetuses, 6 cases (35.3%)showed that premature atrial contraction with normal structure of fetal heart. All of the neonates survived postnatally and 24 of them (92.3%) accepted follow-up. Echocardiograms for16 neonates were performed and 2 of them were identified as atrial septal defects with normal heart rhythms. The incidence of structure heart disease in fetal arrhythmia is 7.7%. Conclusion The prognosis is well for most of the fetuses with arrhythmias, the incidence of heart structure disease is very low among them. We should pay attention to diagnose the fetus of heart structure disease with persistant bradycardia. Temporization for the management of arrhythmiatic fetuses should be accepted and the decision for termination of pregnancy should be made according to obstetric indication.
