Epicardial lipomatous hypertrophy (ELH) is a rare histologically benign condition characterized by excessive accumulation of epicardial fat. We report a case of a 68-year-old female who experienced reduced effort tolerance for the past year. A transthoracic echocardiogram revealed a suspicious circumferential mass around the heart. Cardiac magnetic resonance (CMR) was subsequently performed and identified a 13- to 15-mm-thick layer of epicardial fat surrounding the myocardium, with a small pericardial effusion at the lateral wall. Cardiac function was preserved, and her symptoms were ultimately attributed to atherosclerotic coronary disease, which was treated accordingly. This case highlights the importance of using complimentary multimodal imaging such as CMR, to differentiate between ELH and others, for accurate diagnosis and further management.

OBJECTIVETo investigate the clinical efficacy and safety of modified stapled transanal rectal resection (STARR) combined with perioperative pelvic floor biofeedback therapy (POPFBFT) in treating obstructed defecation syndrome (ODS).

METHODSThirty female ODS patients underwent modified STARR (resection and suture was performed in rectocele with one staple) combined with POPFBFT in Department of Colorectal and Anal Surgery, The First Hospital of Jilin university from October 2013 to March 2015. Before the modified STARR, patients received a course of POPFBFT (20 min/time, 2 times/d, 10 times as a course), and another 2 courses were carried out in clinic after discharge. Efficacy evaluation included general conditions of patients, morbidity of postoperative complication, overall subjective satisfaction (excellent: without any symptoms; good: 1 to 2 times of laxatives per month and without the need of any other auxiliary defecation; fairly good: more than 3 times of laxatives per month ; poor: with no improvement; excellent, good, fairly good are defined as effective), Longo ODS score (range 0 to 40 points, the higher the score, the more severe the symptoms), gastrointestinal quality of life index(GIQLI)(range 0 to 144 points, the lower the score, the more severe the symptoms), anorectal manometry and defecography examination. The follow-up lasted 12 months after operation (ended at April 2016).

RESULTSAverage age of 30 patients was 57(46 to 72) years and Longo ODS score of every patient was ≥9 before operation. The modified STARR was completed successfully in all the 30 patients with average operation time of 25 (18 to 34) min and average hospital stay of 6(4 to 9) d. Postoperative complications included pain(20%, 6/30), urinary retention (16.7%, 5/30), anorectal heaviness (6.7%, 2/30), and fecal urgency(26.7%, 8/30). Anaorectal heaviness and fecal urgency disappeared within 3 months. No severe complications, such as postoperative bleeding, infection, rectovaginal fistula, anastomotic dehiscence and anal incontinence were observed. The effective rate of overall subjective satisfaction was 93.3%(28/30) during the follow-up of 12 months. There was no significant difference in Longo ODS score between pre- POPFBFT and pre-operation (pre- POPFBFT: 32.95±3.22, pre-operation: 32.85±3.62, t=1.472, P=0.163). Compared with pre-POPFBFT, Longo ODS score at 1 week after operation decreased (t=4.306, P=0.000), moreover, score at 1 month after operation was lower than that at 1 week (13.05±7.49 vs. 15.00±7.17, t=7.322, P=0.000), while no significant differences were found among 1, 3, 6, 12 months after operation (F=2.111, P=0.107). Likewise, there was no significant difference in GIQLI score between pre-POPFBFT and pre-operation (pre-POPFBFT: 79.39±17.14, pre-operation: 76.65±17.56, t=1.735, P=0.096). Compared with the pre-POPFBFT, GIQLI score at 1 week after operation increased (t=4.714, P=0.000), moreover, GIQLI score at 1 month after operation was higher than that at 1 week (102.26±19.24 vs 91.31±21.35, t=5.628, P=0.000), while no significant differences were found among 1, 3, 6, 12 months after operation(F=1.211, P=0.313). In comparison with pre- POPFBFT, parameters of defecography examination at 12 months after operation showed obvious improvement: the rectocele decreased from (34.1±0.4) mm to (3.1±0.3) mm (t=6.847, P=0.000), anorectal angle during defecation increased from (123.8±6.7)degree to (134.7±8.5)degree, enlargement of anorectal angle during defecation increased from (29.1±3.5)degree to (37.1±5.3)degree, while no significant differences in descend of perineum, anorectal angles at rest as well as parameters of anorectal manometry were found (all P>0.05).

CONCLUSIONModified STARR combined with POPFBFT is safe and effective for ODS patients.

BACKGROUNDHemodynamic evaluation is crucial for the management of patients with pulmonary hypertention. Clinicians often prefer a rapid and non-invasive method. This study aimed to examine the feasibility of transthoracic echocardiography for the measurements of hemodynamic parameters in patients with pulmonary hypertension.

METHODSA prospective single-center study was conducted among 42 patients with pulmonary hypertension caused by different diseases. Transthoracic echocardiography and right-heart catheterization were performed within 24 hours. Pulmonary artery systolic, diastolic and mean pressure (PASP, PADP and PAMP), cardiac output (CO), and pulmonary capillary wedge pressure (PCWP) were measured by both methods. A linear correlation and a Bland-Altman analysis were performed to compare the two groups of hemodynamic parameters.

RESULTSA good correlation was found between invasive and non-invasive measurements for PASP (r = 0.96), PADP (r = 0.85), PAMP (r = 0.88), CO (r = 0.82), and PCWP (r = 0.81). Further agreement analysis done by the Bland-Altman method showed that bias and a 95% confidence interval for PASP, PADP, and CO were clinically acceptable while great discrepancies existed for PAMP and PCWP.

CONCLUSIONSThe non-invasive measurements by PASP, PADP, and CO in patients with pulmonary hypertension correlate well with the invasive determinations. Transthoracic echocardiography (TTE) was inappropriate for estimating PCWP and PAMP.

BACKGROUNDThe potential application of retinoic acid receptor activators, such as all trans-retinoic acid (ATRA), for treating various cancers have been studied both pre-clinically and clinically. Whether ATRA has an anticancer effect on human esophageal squamous cancer cell (ESCC) is still unknown. We have explored the anticancer effect of ATRA in ESCC, and in this study, the effects of ATRA on levels and patterns of expression of the vascular endothelial growth factor (VEGF) signal transduction pathway in transplantable tumor growth of the human ESCC cell line, EC9706, in nude mice.

METHODSThe animal model of the ESCC xenograft was made by subcutaneous implantation of tumor cells into nude mice. Reverse transcription-polymerase chain reaction (RT-PCR), Western blotting and immunohistochemical assays were used to detect the expression of the VEGF signal transduction pathway in ESCC xenograft tissues.

RESULTSCompared to the control group, the tumor inhibition rates in the low dose ATRA, high dose ATRA, and 5-FU groups were 83.21%, 88.32%, 91.02%, respectively. The protein and mRNA levels of VEGF were down-regulated after being treated with ATRA and 5-FU compared to the control group (P < 0.05). The study also revealed that ATRA specifically down-regulated VEGF and the component of the VEGF signal transduction pathway of CD31, CD34, and CD105 (component of the TGF-β receptor) in ESCC xenograft tissues (P < 0.05).

CONCLUSIONSATRA can significantly inhibit tumor growth and has anticancer effects on transplantable tumor growth of human ESCC cell line EC9706 in nude mice. These findings indicate that ATRA specifically down regulated VEGF and the components of VEGF signal transduction, which may be an important mechanism responsible for the neoangiogenesis inhibition of ESCC cells.

Objective To investigate the characteristics of the colon polyp in a northwest district of China. Methods 112 cases of patients from 1~18 years old, diagnosed with polyps by means of colonoscopies reference centers were followed-up from January 2015 to December 2016. The clinical variables evaluated in this study included: gender, age, symptoms, age at onset of symptoms, age at identification of the polyp, interval of time between the onset of symptoms and the endoscopic diagnosis of colonic polyps, and family history of colon polyp and/or colorectal cancer. The characteristics of the polyps also included: number, morphological type, diameter, histology, and distribution. The case records of these patients were reviewed. The demographics, clinical course, laboratory results, endoscopic and histopathological features, treatments, and outcomes were analyzed. Results In the 112 patients, the median age was 6.9 years, of which 64.3% (72/112) were male. All the patient had the symptom of hematochezia and just a little of the patients have the symptoms of abdominal pain, prolapse of anal polyp and diarrhea. 9.8% (11/112) was mild anemia and the anemia patient all had the symptom of hematochezia of more than 6 months and have no connection with the polyp location. Juvenile polyps were identified in 91.9% (103/112) patients, inflammatory polyp were identified in 7.1% (8/112) and 0.9% (1/112) were identified with adenoma. 1.8% (2/112) of the patient had the family history of colorectal polyp. Conclusions The morbidity of colorectal polyp in children and adolescents in our region is high. The male was significantly more common seen than female. A little proportion of the patient had the family history of colorectal polyp. The hematochezia could be seen in all patients A little proportion of the patient was mild anemia and the anemia patient all had the symptom of hematochezia of more than 6 months. Mainly the polyp was located in the rectum and sigmoid. Juvenile polyps were the major pathologic type and then the inflammatory polyp and adenoma. The adenoma may located in other place than rectum and sigmoid.

Acute respiratory distress syndrome(ARDS)and acute lung injury are grave syndromes associated with high morbidity of the mortality.Currently,the criteria for the classification of the severity of ARDS are the PaO 2/FiO2values, while OI,S/F and OSI values are also used as ancillary diagnostic and grading criteria for ARDS.In this review,we sum-marize the effects of four indicators on the diagnosis and severity of ARDS patients,their respective strengths and weaknes-ses,and predit the future development of the classification of severity of ARDS.

OBJECTIVETo describe the epidemiological characters of pregnancy-induced hypertension (PIH) in Jiaxing areas of Zhejiang province of China between 1995 and 2000.

METHODSWe analyzed the perinatal health surveillance data that was collected as part of the Sino-American cooperative project on neural tube defects prevention established in 1992. The study population consisted of 136 070 pregnant women with at least 20 weeks of gestational age. National diagnostic criteria were used to identify the cases which were divided into three subgroups: mild, moderate and severe.

RESULTS15 127 cases were identified and the overall incidence rate of PIH was 11.1% (95% CI : 11.0% - 11.3%). Among all the cases, mild, moderate and severe PIH were accounted for 71.4%, 22.3% and 6.3%, respectively. The proportions of PIH cases that occurred in the second trimester, third trimester and during delivery appeared to be 4.2%, 34.4% and 61.4%, respectively. There was a significant fall in the trend of PIH occurrence every year, which dropped from 10.7% in 1995 to 8.6% in 2000 by 19.6%. More risk of PIH seemed to be related to those mothers living in the urban areas with age under 20 or above 35, being peasants and having little educational, having had multiple gestations, conceiving in spring/summer or delivering in winter or spring etc. Compared with the results of national survey in 1988, the incidence rate of PIH was higher by 18.1%, while the proportion of severe PIH was much lower by 68.8%. Although the incidence rates of PIH in urban and rural areas were somehow similar, the proportion of severe PIH in rural areas was much higher than that in urban areas.

CONCLUSIONOverall incidence rate and distribution of PIH were reported. Compared with the results in 1988, incidence rate of PIH was much higher, particularly for mild cases.

BACKGROUNDTo explore the cut-off period of subclassification and pathological features of severe hepatitis (SH).

METHODSBased on combined clinical and pathological analyses, the complete clinical and biopsy or autopsy liver tissues data from 196 cases of patients with severe hepatitis were investigated. Meanwhile, proliferative hepatocytes, cholangioepithelia and collagens were identified by a panel of monoclonal antibodies such as those against albumin, cytokeratin 18,19 and collagen I, III with immunohistochemical method.

RESULTSThe clinical and pathological analyses indicated the cut-off periods of acute, subacute and chronic SH (ASH,SSH and CSH) were (13.4+/-7.2) d, (77.4+/-69.3) d and (80.5+/-63.2) d, respectively. Among all SH cases, one case of ASH patient presented clinical manifestation and pathological changes of ASH for 21 days, however, one patient with SSH was demonstrated 12 day course by histological examination. The time of cut-off period between ASH and SSH in child cases was shorter than that in adult cases. Histologically, ASH liver tissues showed massive and/or submassive necrosis caused by one attack, with congestive sinusoid frameworks and proliferative cholangioepithelium-like hepatocytes, while SSH liver tissues presented combined fresh and old submassive or massive necrosis caused by multiple attacks, accompanied by obviously proliferative bile ducts and sinusoid framework collapse.However, the pathological changes of CSH showed ASH- or SSH-like lesions on the background of chronic liver injury.

CONCLUSIONOur data indicated that the cut-off period between ASH and SSH is in accordance with the Scheme of Viral Hepatitis Prevention and Therapy, China, published in 2000, but excluded a part of child SH cases. In our study, the authors found a few pathological features in ASH and SSH.

OBJECTIVETo evaluate the long-term effect of sodium glycididazole (CMNa) as a hypoxic radiosensitizer on the radiotherapy for nasopharyngeal carcinoma.

METHODSBetween May 1999 and May 2002, 211 patients with pathologically confirmed nasopharyngeal carcinoma were randomized into group-A treated by radiotherapy plus CMNa or group-B by radiotherapy alone. The staging was determined according to 92' Fuzhou staging systerm. The type, procession and dosage of radiotherapy were identical in both groups. The early adverse effect grade was assessed based on the CTC2.0 criteria and the late adverse effects were evaluated according to the RTOG/EORTC criteria. The median follow-up time was 52 months. All the data was analyzed by the SPSS 13.0 software. Characteristics and adverse events of these patients were compared between the two groups using t-test and the Wilcoxin rank sum test. Time-to-event curves were estimated using the Kaplan-Meier method. The prognostic parameters were analyzed using univariate analysis and the Cox multivariate regression analysis.

RESULTSThe clinical data of the two groups were comparable. The 3-year survival was 88.4% in group-A, while 75.2% in group-B, with a statistically significant difference between two groups (P = 0.010). Univariate analysis showed that the 3-year survival was statistically correlated with N-staging ((N0-1, 86.9%, N2-3 73.8%, P < 0.001), T-staging (T1-2 85.6%, T3-4 79.3%, P = 0.014), TNM staging (P = 0.039), and whether using CMNa or not during rediotherapy (Group-A 88.4%, Group-B 75.2%, P = 0.010). The 5-year recurrence-free survival, 5-year metastasis-free survival and 5-year overall survival were 75.8%, 74.9% and 77.7% in Group-A, while 63.0%, 63.0% and 62.4% in Group-B with a statistically significant difference between two groups (0.013, 0.022 and 0.010, respectively). If stratified in the subgroups, the overall survival of stage III - IV patients was statistically different between group A and B (P = 0.009), however, not of stage I - II patients (P = 0.502). Cox multivariate regression analysis showed that the independent prognostic parameters for survival were N-stage (RR = 3.288) , T-stage (RR = 2.147) and use of CMNa during rediotherapy (RR = 0.407). However, there was no statistically significant difference between two groups in acute or late adverse effects on nervous system or heart, which suggested that use of CMNa during radiotherapy would not aggravate the toxicity caused by radiotherapy.

CONCLUSIONSodium glycididazole is well tolerable effective as a hypoxic radiosensitizer, which can improve the efficacy of radiotherapy and the long-term result of nasopharyngeal carcinom a patients, especially for the stage III - IV patients.
