To study the characteristics of heart rate rhythm in pregnant women at different trimester of pregnancy, and to explore the relationship between the basic rhythm of heart rate and pregnancy complications. Thirteen pregnant women who were diagnosed with normal early pregnancy in the Reproductive Center of the Second Affiliated Hospital of Soochow University from June 2018 to December 2019 were prospectively selected. Personal files were created and the heart rate data of pregnancy women was collected 24 hours a day by wearable devices until delivery. Prenatal examination and pregnancy outcomes were surveyed at follow-up. The cosine analysis method and the designed statistical module were used to analyze the long-term rhythm of pregnant women's heart rate. The heart rate of pregnant women showed a significant rhythm at different gestational weeks. Compared with the gestational week of 12, the midline-estimating statistic of rhythm(MESOR) increased significantly at the gestational week of 28 and 32 (t=-2.751,P=0.013;t=-2.314,P=0.032).The phase of rhythm shifted from 14∶00 pm in the first trimester of pregnancy (12 weeks) to 16∶00 pm in the second trimester (24 weeks) (t=2.613,P=0.018) and returned to 14∶00 pm at the third trimester (32 weeks) (t=-2.176,P=0.046). Season had no significant effect on the changes of MESOR, amplitude and phase of maternal heart rate in the first trimester (t=-0.356,P=0.729;t=-0.777,P=0.464;t=-0.434,P=0.673), while season had no significant effect on the changes of MESOR, amplitude and phase in the third trimester (t=-0.663,P=0.532;t=-0.209,P=0.841;t=0.625,P=0.592). The heart rate of one pregnant woman with natural delivery had rhythm disorder from the start of labor to delivery. The heart rate of one pregnant woman with premature rupture of membranes showed rhythm disorder before and after the rupture of membranes, and smaller amplitude. Rhythm disturbance may play a suggestive role in preterm delivery and labor initiation. In conclusion, pregnancy may cause changes in the internal heart rate rhythm. Maternal internal rhythm disturbance may occur when delivery or premature rupture of membranes occurs. The heart rate rhythm of pregnant women may be related to some common complications of pregnancy such as premature rupture of membranes.

BACKGROUND: The endovascular approach to aortic disease treatment has been increasingly utilized in the past 2 decades. This study aimed to determine the long-term results of using the Seal thoracic stent graft. METHODS: We retrospectively reviewed the outcomes of patients who underwent thoracic endovascular aortic repair or a hybrid procedure using the Seal thoracic stent graft (S&G Biotech, Seongnam, Korea) from January 2008 to July 2018 at a single institution. We investigated in-hospital mortality and the incidence of postoperative complications. We also investigated the mid-term survival rate and incidence of aorta-related complications. RESULTS: Among 72 patients with stent grafts, 15 patients underwent the hybrid procedure and 21 underwent emergency surgery. The mean follow-up period was 37.86±30.73 months (range, 0–124 months). Five patients (6.9%) died within 30 days. Two patients developed cerebrovascular accidents. Spinal cord injury occurred in 2 patients. Postoperative renal failure, postoperative extracorporeal membrane oxygenation support, and pneumonia were reported in 3, 1, and 6 patients, respectively. Stent-related aortic complications were observed in 5 patients (6.8%). The 1- and 5-year survival and freedom from stent-induced aortic event rates were 81.5% and 58.7%, and 97.0% and 89.1%, respectively. CONCLUSION: The use of the Seal thoracic stent graft yielded good mid-term results. Further studies are needed to examine the long-term outcomes of this device.

PURPOSE: The use of endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysms (r-AAA) is steadily increasing. We report early experiences of EVAR for r-AAA performed in two tertiary referral centers in Korea. METHODS: We retrospectively reviewed r-AAA patients treated by EVAR from May 2013 to December 2017. An EVAR-first strategy for r-AAA was adopted whenever feasible. The demographic information, anatomic characteristics, operative details, postoperative complications with special attention to abdominal compartment syndrome (ACS), and 30-day mortality were collected and analyzed. RESULTS: We identified 13 patients who underwent EVAR for r-AAA. Mean age was 74.2 years and mean AAA size was 74.2 mm. Two patients underwent cardiopulmonary resuscitation at initial presentation. Bifurcated stent grafts were used in 12 out of 13 cases and physician-modified endografts with fenestrated/chimney techniques were performed in 2 cases with short neck. Successful stent graft deployment was achieved in all cases. Three patients were suspected of having ACS and 2 of them underwent laparotomy for decompression. The 30-day mortality was 7.7% (1 of 13), the only mortality being a patient that refused decompressive laparotomy for suspected ACS. CONCLUSION: Despite the small numbers, the outcomes of EVAR for treatment of r-AAA were very promising, even in selected cases with unfavorable anatomy. These outcomes were achieved by a dedicated and well-trained team approach, and by use of high-end angiographic technology. Finally, ACS after EVAR is not uncommon, and requires a high index of suspicion as well as liberal use of decompressive surgery.

Chinese Medical Journal 2019;132(9):1037-1044
BACKGROUND:
Cardiac rupture (CR) is a major lethal complication of acute myocardial infarction (AMI). However, no valid risk score model was found to predict CR after AMI in previous researches. This study aimed to establish a simple model to assess risk of CR after AMI, which could be easily used in a clinical environment.
METHODS:
This was a retrospective case-control study that included 53 consecutive patients with CR after AMI during a period from January 1, 2010 to December 31, 2017. The controls included 524 patients who were selected randomly from 7932 AMI patients without CR at a 1:10 ratio. Risk factors for CR were identified using univariate analysis and multivariate logistic regression. Risk score model was developed based on multiple regression coefficients. Performance of risk model was evaluated using receiver-operating characteristic (ROC) curves and internal validity was explored using bootstrap analysis.
RESULTS:
Among all 7985 AMI patients, 53 (0.67%) had CR (free wall rupture, n = 39; ventricular septal rupture, n = 14). Hospital mortalities were 92.5% and 4.01% in patients with and without CR (P < 0.001). Independent variables associated with CR included: older age, female gender, higher heart rate at admission, body mass index (BMI) <25 kg/m, lower left ventricular ejection fraction (LVEF) and no primary percutaneous coronary intervention (pPCI) treatment. In ROC analysis, our CR risk assess model demonstrated a very good discriminate power (area under the curve [AUC] = 0.895, 95% confidence interval: 0.845-0.944, optimism-corrected AUC = 0.821, P < 0.001).
CONCLUSION
This study developed a novel risk score model to help predict CR after AMI, which had high accuracy and was very simple to use.

PURPOSE: We compared the posterior capsule rupture (PCR) rate between microscope versus intracameral illumination in phacoemulsification surgery performed by novice ophthalmologists. METHODS: We conducted a retrospective chart review of 300 eyes of 211 patients who underwent phacoemulsification by novice ophthalmologists from March 2012 to October 2017. Novice ophthalmologists (n = 6) were divided into those using microscope illumination (n = 4) and intracameral illumination users (n = 2). The first 50 cataract surgery cases of each novice ophthalmologist were reviewed. The results using a phacoemulsification machine and microscopy were the same. The intraoperative complications and learning curve in each case were evaluated. RESULTS: Phacoemulsifications performed by novice ophthalmologists showed a statistically significant difference in PCR rate between the microscope illumination (19.0%, 38/200) and intracameral illumination (4.0%, 4/100) groups (p = 0.001). The incidence of PCR was reduced to 22%, 18%, 16%, 12%, and 8% per 10 cases in the microscope group, while it was 15% in the first 10 cases and 0% in 50 cases thereafter in the intracameral illumination group. CONCLUSIONS: Novice surgeons had a lower PCR rate during cataract surgery using intracameral illumination than using microscope illumination. Both groups showed a tendency for the PCR to decrease with increasing surgical cases, but the intracameral illumination group showed a shorter learning curve.

OBJECTIVE:
To analyze the morphological features and forensic pathological characteristics of cardiac ruptures of different causes for their differential diagnosis.
METHODS:
We analyzed the data of 44 autopsy cases of cardiac rupture from 2014 to 2017 in our institute, including 11 cases caused by blunt violence with intact pericardium, 4 caused by cardiopulmonary resuscitation (CPR), 9 by myocardial infarction, and 20 by aorta dissection rupture.The gross features and histopathological characteristics of cardiac rupture and pericardial effusion were analyzed and compared.
RESULTS:
Cardiac ruptures caused by blunt violence varied in both morphology and locations, and multiple ruptures could be found, often accompanied with rib or sternum fractures; the volume of pericardial effusion was variable in a wide range; microscopically, hemorrhage and contraction band necrosis could be observed in the cardiac tissue surrounding the rupture.Cardiac ruptures caused by CPR occurred typically near the apex of the right ventricular anterior wall, and the laceration was often parallel to the interventricular septum with frequent rib and sternum fractures; the volume of pericardial blood was small without blood clots; microscopic examination only revealed a few hemorrhages around the ruptured cardiac muscular fibers.Cardiac ruptures due to myocardial infarction caused massive pericardial blood with blood clots, and the blood volume was significantly greater than that found in cases of CPR-induced cardiac rupture ( < 0.05);lacerations were confined in the left ventricular anterior wall, and the microscopic findings included myocardial necrosis, inflammatory cell infiltration, and mural thrombus.Cardiac tamponade resulting from aorta dissection rupture was featured by massive pericardial blood with blood clots, and the blood volume was much greater than that in cases of cardiac ruptures caused by blunt violence, myocardial infarction and CPR ( < 0.05).
CONCLUSIONS
Hemorrhage, inflammatory cell infiltration, and lateral thrombi around the cardiac rupture, along with pericardial blood clots, are all evidences of antemortem injuries.

ObjectiveTo investigate the diagnosis and management of penile fracture.
METHODSFrom June 1993 to May 2017, 46 cases of penile fracture were treated in our hospital, averaging 33.5 (25-42) years of age and 3.45 (1-10) hours in duration, of which 41 occurred during sexual intercourse, 4 during masturbation and 1 during prone sleeping, 4 with hematuria, but none with dysuria or urethral bleeding. Hematoma was confined to the penis. Emergency surgical repair was performed for all the patients, 45 under spinal anesthesia and 1 under local anesthesia, 16 by coronal proximal circular incision and the other 30 by local longitudinal incision according to the rupture location on ultrasonogram. The tunica albuginea ruptures averaged 1.31 (0.5-2.5) cm in length, which were sutured in the "8" pattern for 6 cases and with the 3-0 absorbable thread for 18 cases. The skin graft or negative pressure drainage tube was routinely placed, catheters indwelt, and gauze used for early pressure dressing. In the recent few years, elastic bandages were employed for 3-5 days of pressure dressing and antibiotics administered to prevent infection. The stitches and catheter were removed at 7 days after surgery.
RESULTSShort-term postoperative foreskin edema occurred in 14 of the 16 cases of circular degloving incision, but no postoperative complications were observed in any of the cases of local incision. Twenty-eight of the patients completed a long-term follow-up of 49.4 (10-125) months, which revealed good erectile function, painless erection, and satisfactory sexual intercourse.
CONCLUSIONSFor most penile fractures, local longitudinal incision is sufficient for successful repair of the tunica albuginea, with mild injury, no influence on the blood supply or lymph reflux, and a low rate complications. It therefore is obviously advantageous over circular degloving incision except when the cavernous body of urethra is to be explored, which necessitates circular degloving incision below the coronal groove.
