ABSTRACT

Objective:To evaluate the long-term results of bipolar radiofrequency(BRF) ablation in restoring sinus rhythm in patients with permanent atrial fibrillation(AF) undergoing surgery for cardiac surgery.Methods:This retrospective study sample consisted of 268 patients with LSP-AF underwent cardiac operations concomitant BRF maze Ⅳ procedure. Data were collected prospectively on perioperative outcomes, rhythm status, survival, and clinical events.Results:15 patients died in the early postoperative period, perioperative mortality rate was 5.5%. The rate of stable sinus rhythm(sSR)was 86.6%, 75.4%, 67.7%, 57.8% in 1, 2, 5, 8 years after operation. Multivariate analysis proved the size of the left atrium( HR=1.073, P<0.001) and duration of AF( HR=1.070, P=0.025) to be an independent predictor of the radiofrequency ablation outcome. Conclusion:Bipolar radiofrequency maze procedure can effectively eliminate AF, maintain long-term of sinus rhythm. Bipolar radiofrequency maze procedure is a safe, easy and effective surgical option for the treatment of AF, with satisfactory long-term results, is worthy of promotion.

ABSTRACT

Objective:To evaluate the long-term results of combined ganglion plexus ablation(GPA) during radiofrequency ablation(RF) with long-standing persistent atrial fibrillation(LSP-AF).Methods:This retrospective study sample consisted of 268 patients with LSP-AF underwent valve operations concomitant RF maze Ⅳ procedure. Data were collected prospectively on perioperative outcomes, rhythm status, survival, and clinical events. Propensity score matching conducted by RF and RF+ GPA resulted in 102 patients per group.Results:Independent predictors for rhythm success at 1 year were combined GPA( OR=0.205, P=0.005), smaller left atrium size( OR=1.091, P=0.000); at 5-year and 8-year were a shorter history of AF( OR=1.069, P=0.023; OR=1.066, P=0.030), and smaller left atrium size( OR=1.091, P=0.000; OR=1.086, P=0.000). After matching, RF+ GPA group had significantly higher sinus rhythm(SR) without antiarrhythmic drugs(AADs) at 6 months(91.3% vs. 79.8%, P=0.026), 1-year(90.2% vs. 78.5%, P=0.028), but there were no difference between the two groups at 5-year(64.8% vs. 64.4%, P=0.956), and 8-year(53.3% vs. 50.6%, P=0.711). During the 6 postoperative months, fewer patients in the RF+ GPA group underwent follow-up cardioversions(2.0% vs. 8.8%, P=0.030). Actuarial survival curves did not differ significantly between the 2 groups( HR=1.327, 95% CI 0.4633-3.802, P=0.598). Conclusion:The combination of GPA can be effective at the early postoperative stage for SR restoration in Maze Ⅳ procedures for the treatment of LSP-AF in heart valve surgeries, particularly for lower AADs use and lower cardioversions. However, this effect will gradually diminish after one year.

ABSTRACT

Objective:To assess surgical outcomes of implanted porcine small intestinal submucosa (SIS) mesh in the rabbit vesicovaginal space (VVS) and explore its application value in pelvic floor reconstruction surgery.Methods:Sixteen male rabbits were randomly divided into four groups, and each group had four rabbits. All groups of rabbits were implanted with SIS mesh in the vesicovaginal space. They were humanely killed after a postoperative period of 7, 30, 90 and 180 days by group. The grafted area was removed with the surrounding bladder and vaginal tissues. The specimens were embedded in paraffin and then stained with HE and Masson's trichrome stains for visual observations, cells counts, and assessment of tissues and collagen fibers.Results:(1) After HE staining, a large number of inflammatory response cells mainly eosinophils and lymphocytes infiltrated around the SIS mesh in 7 days group, and neovascularization was observed, the infiltration area of inflammatory response cells further increased in 30 days group, the infiltration area of inflammatory response cells significantly reduced in 90 days group, while the inflammatory response basically subsided in 180 days group. (2) After Masson's trichromestaining, the collagen structure of SIS mesh in 7 days group was clear and intact. While, the collagen structure of SIS mesh was partially degraded in 30 days group, the SIS meshes of 4 rabbits were completely degraded, but the collagen fragments of SIS remained in 90 days group. In 180 days group, the SIS mesh of all rabbits was degraded, and one of them had the formation of new collagen fibers.Conclusions:SIS mesh implanted into the VVS of rabbits can lead to a transient non infective inflammatory reaction, which could be completely degraded and a small amount of new collagen fibers could be produced after 180 days of implantation. Which shown that SIS mesh should be used cautiously in pelvic floor reconstruction surgery.

ABSTRACT

@#Objective    To analyze the recovery rule of atrial contractility (AC) function after Maze Ⅳ procedure of valvular atrial fibrillation (AF). Methods    In our hospital from March 2016 to April 2018, 103 patients who underwent cryoablation Maze Ⅳ procedure due to mitral valve lesions associated with persistent or long-term persistent AF were enrolled. There were 42 males and 61 females, with an average age of 58.5±9.1 years. Electrocardiogram and echocardiography were followed up at discharge and 1, 3, 6, 12 months after procedure. A multivariate Cox analysis of predictive factors for AC recovery was applied. Results    All the 103 patients were followed up for 1 year. The recovery rate of AC increased gradually after operation. It was not until 3 months after procedure that most of the right atrial contractility (RAC) was accompanied by synchronous recovery of the corresponding left atrial contractility (LAC, Kappa coefficient≥0.40, P<0.05). However, the coexistence of sinus rhythm (SR) and bilateral AC was not consistent well until 1 year after operation (Kappa coefficient≥0.40, P<0.05). One year after procedure, the recovery rates of SR and bilateral AC were 86.4% (89/103) and 66.0% (68/103) respectively. By Cox multivariate regression analysis, longer preoperative AF duration (P=0.040), larger preoperative left atrial diameter (LAD, P=0.003), and AC deletion 3 months after surgery (P=0.037) were predictive factors for AF recurrence in the middle and advanced stages (>3 months) after Maze surgery. At the same time, longer preoperative AF duration and larger preoperative LAD were also negative predictors of middle and late recovery of LAC and bilateral AC (All P<0.05). Receiver operating characteristic curve analysis showed that the best critical value of preoperative AF time and preoperative LAD for prediction of AC recovery was 37 months (sensitivity 99.6%, specificity 76.3%) and 60.5 mm (sensitivity 98.5%, specificity 78.9%), respectively. Conclusion    The recovery of AC after Maze procedure is a dynamic improvement process. Early recovery of AC is beneficial to the stable maintenance of SR in the future. Prolonged duration of AF and enlarged LAD have adverse effects on the outcome of Maze Ⅳ procedure.

ABSTRACT

Objective To access the influence factors of diagnostic delay of endometriosis. Methods We designed a questionnaire of diagnostic delay of endometriosis. From February 2014 to February 2016,400 patients who had dysmenorrhea and diagnosed with endometriosis by surgery in Peking University Third Hospital were surveyed retrospectively. Time and risk factors of diagnostic delay were analyzed.Results The diagnostic delay of 400 patients was 13.0 years(0.2-43.0 years),78.5%(314/400) patients thought pain was a normal phenomenon and didn′ t see the doctor. Patients who suffered dysmenorrhea at menarche experienced longer diagnostic delay than those who had dysmenorrhea after menarche(18.0 vs 4.5 years;Z=191.800,P<0.01).Patients who suffered aggravating dysmenorrhea experienced shorter delay time than those who suffered stable or relieving dysmenorrhea(11.0 vs 12.5 vs 18.0 years;Z=8.270, P<0.05), with the difference statistically significant, single factor analysis shows. Severe dysmenorrhea, deep infiltration endometriosis(DIE), family history of dysmenorrhea or endometriosis, previous surgical history of endometriosis,high stage,with infertility,adenomyoma or other symptoms,could help to shorten diagnostic delay with no significant difference(P>0.05). By multiple logistic regression analysis,the results shown that whether have dysmenorrhea at menarche and clinical diagnosis time were the independent factors affecting delayed diagnosis(P<0.01).Conclusions Diagnostic delay of endometriosis is common and the mean delay time is 13.0 years mainly due to the unawareness of dysmenorrhea. Dysmenorrhea at menarche,clinical diagnosis time and dysmenorrhea intensity are the factors affecting time of diagnostic delay.

ABSTRACT

Objective To investigate the diagnostic value of dynamic MRI with coupling agent filled vaginal and rectumin the display of vaginal vault prolapse and rectocele. Methods Thirty three female patients, who were diagnosed with pelvic organ prolapse with Ⅲ degrees and above by gynecologic outpatient clinic and prepared to be treated with surgery were prospectively collected. All of them underwent two types of dynamic MRI, one was routine dynamic MRI (Group A) and the other was dynamic MRI with vaginal and rectum filled with coupling agent (Group B). Two radiologists evaluated and scored the display of vaginal vault and rectocele on these two groups of dynamic MRI images. According to the joint result of two radiologists, two gynecologists made surgical planning. Kappa test was used to compare the consistency of scores performedby two radiologists, and Fisher exact test was used to compare the differentiation fromboth groups, as well as the differentiation of probability of high uterosacral ligament suspension.Results The Kappa value of both groups was 0.65 and 1.00 respectively, where the consistency of Group B was superior than Group A. There were significant differences between the two groups(P<0.01), where Group B was better than Group A. Based on the imaging results of Group A, 7 patients (21.2%, 7/33) were decided to make high uterosacral ligament suspension. Based on the imaging results of Group B, 20 patients (60.6%, 20/33) were decided to make high uterosacral ligament suspension, and differences were statistical significance between the two groups(P<0.05). Conclusions Fo purpose of the displaying vaginal vault and rectocele, the dynamic MR imaging with vaginal and rectum filled with coupling agent was better than routine method. The proposed method can provide important information and reference for the establishment of surgical planning.

ABSTRACT

BACKGROUND:For patients with degenerative mitral annulus dilatation complicated by atrial fibrilation, atrial fibrilation is needed to be treated concomitant with artificial valve ring implantation. Although Cox maze III procedure is the gold standard for treatment of atrial fibrilation, its safety has been questioned. OBJECTIVE:To evaluate the safety of artificial valve rings implantation and Cox Maze III procedure for treatment of degenerative mitral annulus dilatation complicated by atrial fibrilation. METHODS: A total of 43 patients with degenerative mitral annulus dilatation and atrial fibrilation were enroled and were randomly divided into test group (n=21) and control group (n=22). Patients in the test group were treated with mitral valvuloplasty and Cox Maze III procedure. Patients in the control group were only treated with mitral valvuloplasty. RESULTS AND CONCLUSION: (1) Intraoperative safety indexes: the durations of cardiopulmonary bypass and aortic clamping. and the incidence of hemoglobinuria in the test group were higher than those in the control group (P < 0.001). There was no significant difference in the urine output between these two groups. (2) Postoperative safety indexes: the incidence of atrial dysrhythmia (i.e., any atrial dysrhythmia other than atrial fibrilation), proportion of patients requiring a temporary pacemaker and hospital stays in the test group were higher than those in the control group (P < 0.05). There were no significant differences in the secondary-thoracotomy bleeding rate and incidence of stroke between these two groups. (3) Postoperative outcomes: the rates of cardioversion to achieve sinus rhythm at the day of surgery and at discharge in the test group were significantly higher than those in the control group (P < 0.001). At discharge, patients in both groups were al at NYHA functional class Ior II. Echocardiography showed trace to mild mitral regurgitation and complete closure of the tricuspid valve. There were no significant differences in the left atrial diameter, left ventricular diameter, left ventricular volume, and ejection fraction between these two groups. However, the proportions of mitral and tricuspid valve peak A-waves were significantly higher than those in the control group (P < 0.001). These results show that artificial valve ring implantation and Cox Maze III procedure is a safe and effective method for treating degenerative mitral annulus dilatation complicated by atrial fibrilation during operation.

ABSTRACT

BACKGROUND:Incidence of degenerative mitral regurgitation show a gradual increase tendency,but there is no report on degenerative mitral regurgitation due to pure mitral valve ring expansion in China.OBJECTIVE:To summarze the early and midterm outcomes of pure mitral valve annuloplasty in the treatment of degenerative mitral regurgitation due to pure mitral valve ring expansion. METHODS :Forty-eight patients with degenerative mitrlal regurgitation due to pure mitral valve ring expansion underwent pure mitral valve annuloplasty, including 23 cases treated with Carpentier-Edwards Physio ring and 23 with SJMTM rigid saddle ring.Affter discharge,echocardiography was used to evaluate heart function and mitral regurgitation degree during the follow-up.The outcomes were compared between the two groups. RWSULTS AND CONCLUSION:There was no early death after operation and all cases were cured and discharged.All patients were followed up for 3 months to 4years,and the cardiac function and mitral valve regurgitation were significantly improved (no mitral regurgitation in 36 cases,trivial regurgitation in 10 cases and mild mitral regurgitation in 2cases).According to NYHA grading,there were 32 cases of level 1 and 16 ceses of level Ⅱ. The echocardiography showed that postoperative left atrium diameter, left ventricular end-diastolic diameter, left ventricular end-systolic diameter, pulmonary artery systolic pressure and the ratio of regurgitation beam area to left atrial area were significantly lower than those before operation (P < 0.01). The left ventricular ejection fraction increased greatly (P < 0.01). There was no ring rupture, ring avulsion and hemolysis. Postoperative transvalvular pressure was less than 3 mm Hg. However, there were no significant differences in the above-mentioned parameters between the Carpentier-Edwards Physio ring and SJMTM rigid saddle ring groups. The results suggest that the pure mitral valve annuloplasty is excelent in the treatment of degenerative mitral regurgitation due to pure mitral valve ring expansion, through the right surgical techniques and the right choice of artificial valve ring.

ABSTRACT

BACKGROUND:Artificial valve replacement for valvular disease has good biocompatibility and hemodynamic characteristics, but there are stil many factors that affect its therapeutic effects. OBJECTIVE:To detect the level of serum Apelin-12 in the perioperative period of valve replacement in valvular disease patients with atrial fibrilation. METHODS: Sixty-two patients with valvular heart disease scheduled for artificial valve replacement were selected, including 30 patients with persistent atrial fibrilation (atrial fibrilation group) and 32 patients with sinus rhythm (sinus rhythm group). There were 33 males and 29 females, with a mean age of (55±11) years. Levels of serum Apelin-12 and makers related to inflammation and oxidative stress were detected in two groups at admission. Furthermore, the sinus rhythm group was sub-divided into postoperative atrial fibrilation (POAF) group (n=8) and non-POAF group (n=24) after valve replacement, and the above-mentioned indicators were detected and compared between these two subgroups. RESULTS AND CONCLUSION:Compared with the sinus rhythm group, the serum level of Apelin-12 was significantly lower in the atrial fibrilation group, while the levels of high-sensitivity C-reactive protein and interleukin-6 and total antioxidant capacity were significantly higher in the atrial fibrilation group (P <0.05). Correlation analysis showed that the serum level of Apelin-12 was negatively correlated with high-sensitivity C-reactive protein level and total antioxidant capacity (r=-0.265,P=0.045;r=-0.960,P <0.001), but not correlated with the interleukin-6 level (r=-0.155,P=0.230). Compared with the non-POAF group, the serum level of Apelin-12 was significantly lower in the POAF group (P< 0.05), but the left atrial diameter, high-sensitivity C-reactive protein level were higher in the POAF group (P < 0.05). Apelin-12 may take part in the occurrence and maintenance of atrial fibrilation through the regulation of inflammations and oxidative stresses. The testing of serum Apelin-12 has a certain value in predicting the occurrence of postoperative atrial fibrilation.

ABSTRACT

Objective To investigate the factors influencing therapy decision of surgery or pessary in patients with severe pelvic organ prolapse (POP). Methods Totally 419 cases ofⅢtoⅣdegree POP patients were studied retrospectively. Patients were divided into surgery and pessary groups according to their own choice. Clinical characters were compared such as age, body mass index (BMI), age of onset and disease duration, POP stage, complications. Results 67.5%(283/419) patients were in the surgical group and 32.5%(136/419) patients in the pessary group. Patients in surgical group had higher BMI [(25.1 ± 3.5) versus (23.8±2.6) kg/m2], elder age of onset [(62±12) versus (57±11) years old], longer disease duration [(5± 8) versus (11±11) years] and higher POP staging of middle compartment and less cardiac disease [20.1%(57/283) versus 30.9% (42/136)] than those in pessary group, all had significant difference (P<0.05). Logistic regression analysis on the above factors showed a statistically significant difference between two groups, BMI, disease duration and POP staging of middle compartment were independent factors (OR=1.141, 0.932, 1.389;all P<0.01). Conclusions Patients with higher BMI, higher POP staging of middle compartment and less cardiac disease tended to choose surgery. Patients with younger age of onset and longer disease duration tended to choose pessary. Factors as age, POP staging of anterior and posterior compartment, history of POP surgery, complicated with hypertension and diabetes, showed no influence on treatment choice.

ABSTRACT

Objective To investigate the relevance between expectations before treatment, new symptoms and satisfaction after treatment of the pelvic organ prolapse (POP) patients. Methods Made a collection of 75 cases of POP patients at Peking University Third Hospital, who were affected by the POP symptoms and came to our clinic for treatment from January to December in 2013. Prospectively investigate the patients′expectations before treatment, which were the most troubling symptoms to be solved. According to treatment we divided the patients into surgery and pessary groups. Two groups were followed up with the degree to achieve the desired goals using patient global impression of improvement (PGI-I), new symptoms and satisfaction after treatment, try to find the relevance between expectations before treatment, new symptoms and satisfaction after treatment. Results There were 47 (63%, 47/75) patients in the surgical group and 28 (37%, 28/75) patients in the pessary group. The top three problems for patients were friction when walking (25%, 19/75), dysuria (23%, 17/75) and the feeling of vaginal prolapse (19%, 14/75). The follow-up rate was of 93% (70/75), follow-up time was (5 ± 4) months. Satisfaction score after treatment of surgical group was higher than that of pessary group [(4.9±0.4) versus (4.0±1.3) scores, P<0.01]. There was no statistically significant difference between two groups of PGI-I score [(6.7±0.6) versus (6.6±0.9) scores, P=0.886]. The top three new symptoms after treatment were increased secretion, urinary incontinence and dysuria. PGI-I and satisfaction scores was relevant (P=0.021). The availability of new symptoms and satisfaction scores was relevant (P=0.001). Conclusion When achieving higher expectations to the treatment and no more new symptoms, the satisfaction score after treatment is higher.

ABSTRACT

A large ischemic stroke caused by malignant middle cerebral artery infarction can lead to severe cerebral edema, even cerebral hernia. This condition deteriorates and progresses rapidly, usually leading to death. Due to limitations of conservative treatments, decompressive hemicraniectomy becomes a favored option in clinic. Recent years, a series of ex?perimental studies and clinical trials achieved reliable evidence that decompressive hemicraniectomy is an effective treat?ment for patients who suffer from malignant middle cerebral artery infarction. With the successful surgical procedure, most patients benefit from a reduced mortality and improved functional outcome without severe disability. Nevertheless, plenty of issues about decompressive hemicraniectomy still need to be solved. Here, we reviewed researches of early diagnosis of ma?lignant middle cerebral infarction and the application of decompressive hemicraniectomy as its treatment.

ABSTRACT

Objective: To explore the impact of Ischemic preconditioning (IPC) in aged experimental rats after myocardial ischemia-reperfusion (I/R) with its mechanism. Methods: A total of 32 Wistar rats at the age of (21-23) months were divided into 4 groups, n=8 in each group.①Control group, the rats received cardiac perfusion for 180 min. ②I/R group, the rats received cardiac perfusion for 30 min, followed by ischemia for 30 min, then reperfusion for 120min.③IPC group, the rats received cardiac perfusion for 10 min, followed by ischemia and reperfusion 2 times (5 min in each time), then ischemia 30 min and reperfusion 120 min. ④ Enhanced IPC group, rats received cardiac perfusion for 10 min, followed by ischemia and reperfusion 4 times (5 min in each time), then ischemia 30 min and reperfusion 120 min. The recovery rate of cardiac output (CO), left ventricular developed pressure (LVDP) and the recovery rate of maximum rise and fall of left ventricular pressure (±dp/dtmax) at (30, 60, 90, 120) min after reperfusion were recorded respectively. The creatine kinase (CK-MB), superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were examined before ischemia and 120 min after reperfusion. The apical peroxisome proliferator-activated receptorγco-stimulatory factor 1α(PGC-1α) was examined by immuno-histochemistry. Results: The MDA content, CK-MB, SOD activities LVDP and (±dp/dtmax) recovery were similar between IPC group and I/R group, P>0.05. While compared with I/R group, the Enhanced IPC group showed decreased CK-MB activity and MDA content, increased SOD activity and CO, LVDP and (±dp/dtmax) recovery rate, all P0.05. While compared with I/R group, the Enhanced IPC group had increased PGC-1αexpression, P Conclusion: The cardiac IPC was weakened in aged rats which might be because of decreased PGC-1αexpression, the enhanced IPC may up-regulate PGC-1αexpression and therefore, protect the cardiac tissue in aged experimental rats.

ABSTRACT

Objective To explore the clinical value of MRI in diagnosing and treating cesarean scar pregnancy (CSP).Methods A retrospective analysis was conducted on the clinical manifestations of 54 patients diagnosed with CSP between January 2009 to January 2013 in Peking University Third Hospital.Based on the patients' MRI image and other clinical datas,we did transvaginal operation on patients with CSP1,and transvaginal combined with abdominal operations on patients with CSP2.The intraoperative blood loss,operation time,postoperative hospital stay,and the length of time required for of serum hCG dropping to normal of the patients were analyzed.Results The average age of the 54 patients was (34±5) years and the average duration of gestation was (56± 16) days,all patients' vital sign were stable,the hCG level was 23-142 962 U/L before treatment.Twelve patients were diagnosed with CSP1 by MRI,and 5 of them had focus of 1-2 cm in diameter,the 5 patients' serum hCG level was 436-1 159 U/L and 23-32 days after drug administration,their hCG level returned to normal; the other 7 patients had focus of 2.0-4.4 cm in diameter,and their hCG level was 2 218-63 446 U/L,lesion resection was done on the 7 patients by hysteroscope or under B-uhrasound monitor.Forty-two patients were diagnosed with CSP2,and their focus were 1.0-7.1 cm in diameter,and serum hCG level were 23-142 962 U/L.We did bilateral uterine artery occlusion by laparoscope or laparotomy during operation for 22 patients or bilateral uterine artery embolization (UAE) before operation for 20 patients,then we did lesion resections.The blood loss during operation of CSP1 or CSP 2 was 50.1,267.2 ml; operation time was 30,128 minutes; postoperative hospital stay was 4.6,6.7 days;their serum hCG returned to normal 13-30 days after the surgery.All the 54 patients' uterus were preserved,and the patients undergoing operations were all cured without the second operation.Conclusion MRI is an effective method to conduct clinical treatment in CSP.
