Objective To compare the curative effect and safety of Shang ring circumcision and conventional circumcision .Methods Retrospectively analyzed the clinical data of 329 adult patients who were admitted into our hospital from January 2013 to May 2015, including 205 cases of Shang ring circumcision and 124 cases of conventional circumcision .The operation time , intraoperative and postoperative VAS pain scores , intraoperative bleeding , wound healing time , complications , and degree of penile appearances and overall satisfaction between the two groups were compared .Results Compared with conventional circumcision , Shang ring circumcision was associated with shorter oper-ative time, less intraoperative blood loss , lower intraoperative and postoperative VAS pain scores , lower adverse event rate , higher penile ap-pearances and overall satisfaction , and the difference was statistically significant (P<0.05).Conclusion Shang ring circumcision may be a safer and more effective choice in comparison with conventional circumcision for male patients , as it can shorten the time of operation and save the cost of health care .

Objective To explore the selection of medical unit and the major influencing factors among residents in Hubei province,to allocate reasonably the health resources and provide reference for developing medical policy.Methods With the method of multi-stage stratified cluster sampling,household survey were done.The multilevel statistical model was used to analyze the influencing factors of the first diagnosed agencies.Results The proportions of residents who chose primary medical institutions as the first diagnosed agencies were 64.5％ in urban areas and 84.3％ in rural areas,and the visiting rate decreased as the level of health care institutions increased.The selection of first diagnosed agencies among patients were related to district (city or village,OR=0.463,95％CI..0.254-0.842),age (OR=1.023,95％CI:1.010-1.036),the educational attainment (OR＞1.000),illness duration in days (OR=0.945,95％CI:0.917-0.973) and number of days in bed (OR=0.854,95 ％ CI:0.825-0.884).Conclusion The residents who chose primary medical institutions as the first diagnosed agencies took a large proportion.District,age,the educational attainment and the illness duration in days had influence on the selection of the first diagnosed agencies among residents.

Objective To summarize the clinical experience of surgical intervention for cardiac neoplasm in a fetus . Methods A 32-year-old pregnant woman was admitted to our hospital for complaint of fetal cardiac neoplasm .A separated het-erogenic cardiac occupying lesion was identigied at right atrium of the fetus by echocardiography , whose size is 2.85 cm ×2.25 cm, but the pathogenic origin still remained uncertain, maybe originate from ether pericardium or atrium.The annulus of tri-cuspid valve was compressed nearly 50% with the presence of amount of pericardial effusion.The fetal heart rate decreased at some fetal position resulting in the compression to the heart.So an Ex-utero Intrapartum Therapy(EXIT) procedure was per-formed under the supply of placenta at the 32 weeks of pregnancy.Cesarean section was performed with intact umbilicus and fe-tal circulation by obstetricians.Consequently, the median sternotomy of this fetus and pericardiotomy were performed , with 30 ml clear pericardial effusion drained .The tumor was confirmed to be giant right atrial neoplasm after the intraoperative explora-tion.Considering on the high risk of the cardiopulmonary bypass and limited time for EXIT , the giant atrial neoplasm was left alone with delayed sternum closure after the effectively decompression of the heart .The omphalotomy was successfully per-formed after the EXIT surgery.The neoplasm resection and the repair for its defect on right atrium were performed with cardiop-ulmonary bypass 2 days later.Results Convalesce of this mother was quite good after cesarean resetion .Hemodynamics of the premature baby was satisfatory after the resection of right atrial neoplasm which pathological report was benign hemangioma . Conclusion Via multiple disciplines collaboration , EXIT intervention for fetus is feasible and safe under adequate prepara-tion.

Objective: To investigate the application of one stage otoptasty for congenital atresia of the external acoustic canal and malformations of the middle ear and the auricle. Method: patients with the ear malformations were given surgical reconstruction of one stage otoplasty. The auricle was reconstructed with the rib which was encapsuled with the superthin temporal flap. According to the malformations of the middle ear in patients, Ⅰ style tympanoplasty and Ⅲ style tympanoplasty were carried out respectively. All patients were performed myringoplasty with temporal fascia and reconstructed the external acoustic canal with full thickness skin-grafting. Result:A long term follow-up (4～6 years)demonstrated that 11 ears were survival of which 8 ears figuration were ideal. The hearing improvement was observed in all patients. Conclusion:one stage otoplasty is effective for treatment of the congenital malformations of the external and middle ear.

Objective: To investigate the occurrence of masked hypertension (MH) and the degree of damage to target organs in people with family history of hypertension. Methods: 987 cases of family history of hypertension who had been examined in our hospital from January 2017 to November 2017 were selected as observation group with the approval of hospital ethics committee. At the same time, 987 subjects without family history of hypertension who had been examined in our hospital during the same period were selected as control group. The incidence of masked hypertension, left ventricular mass index (LVMI) and carotid intima-media thickness (IMT) were observed. Results: The incidence of hypertension and masked hypertension in the observation group was significantly higher than that in the control group (P<0.05). LVMI and IMT in patients with masked hypertension were significantly higher than those in normal blood pressure group. LVMI and IMT in patients with hypertension were higher than those in patients with masked hypertension and normal blood pressure group. The LVMI and IMT of patients with family history of masked hypertension were higher than those without family history of masked hypertension. Conclusions Family history of hypertension can increase the incidence of masked hypertension and organ damage of patients. The monitoring of masked hypertension should be strengthened for those with family history of hypertension.

OBJECTIVETo investigate the surgical endpoint of separation of mesorectum during total mesorectal excision (TME), suggesting the concept of "terminal line", in order to perform above separation better for middle-low rectal cancer.

METHODSGross anatomy of mesorectum endpoint from 81 surgical specimens of low anterior resection (LAR, 5 to 6 cm of distance from low margin of cancer to anal edge) and 71 surgical specimens of abdominal perineal resection(APR, <5 cm of distance from low margin of cancer to anal edge) was observed. Clinicopathological, magnetic resonance imaging(MRI) morphological and operative video data of 108 low rectal cancer patients undergoing TME at Department of Colorectal Surgery of Affiliated Union Hospital of Fujian Medical University between March 2016 and March 2017 were retrospectively analyzed. Rates of the "terminal line" exposure of TME between different surgical procedures(robot or laparoscope) and different anatomical instruments (ultrasonic knife or electric hook) were compared for evaluating the site of separation endpoint.

RESULTSThe gross anatomical findings of specimens from LAR showed that the rectal wall below the levator hiatus level had no mesorectum attachment, and gross anatomical finding of specimens from APR showed that the levator hiatus was the most terminal attachment margin of the mesorectum whose thickness was only 2 millimeters in levator hiatus level. MRI morphological findings of 108 low rectal cancer patients showed that high signal intensity of mesorectal tissue on T2 MRI gradually thinned to the level of levator hiatus. High quality laparoscopic and robotic operation revealed a white linear structure formed by pelvic fascia, which covered and surrounded levator hiatus, so the "terminal line" of TME was defined. The operation video of 108 revealed that the overall exposure rate of the "terminal line" was 45.4%, the exposure rate of "terminal line" in robotic surgery was similar to that in laparoscopic surgery [(60.0%(18/30) vs. 39.7%(31/78), P=0.058], while such rate in ultrasonic knife was superior to electric hook [55.4%(41/74) vs. 23.5%(8/34), P=0.002]. Laparoscopy combined with ultrasonic knife can also obtained a high exposure rate of 52.3%(23/44).

CONCLUSIONSThe white linear structure referring to pelvic fascia which covers and surrounds levator hiatus is the "terminal line" of TME. The use of an ultrasonic knife is easier to expose this structure and to guarantee the quality of TME.

Objective To compare the bio-medical parameters in SIV infected Chinese rhesus monkeys with diverse disease progression,by which the pathogenesis of simian AIDS were to be investigated.Methods Sixteen Chinese rhesus monkeys were inoculated intravenously with SIVmac239 and followed-up for 18 months.Based on their progression patterns and plasma viral loads,animals were divided into 3 groups,including 1 rapid progressor( RP),13 normal progressors(NP),and 2 elite controllor(EC).Their parameters of haematology,virology,immunology and pathology were examined and compared. Results Compared with other animals,RM449(RP) showed higher viral load,unresponsive humoral immunity,and higher level of auto-antibodies against lymph node,thymus,and spleen.Additionally,its effector memory CD4 count was lower,with the transformation progress being blocked-like from naive/central memory subsets to effector memory subset,as the flow-cytometry assay showed.Notable decrease in its peripheral B cell was also observed,especially to the sub-population of tissue-like memory B cells and activated memory B cells.Pathological examination showed the depletion of lymphoid tissue,atrophy of spleen and loss of thymus.Moreover,most of these parameters of RM450 and RM453 (EC) changed opposite to that of RP.Conclusion The hallmarks of RM449 were higher viraemia and lower SIV specific IgG level,which may due to the disturbance of T cells and B cells development and differentiation.Moreover,destructions of organs of the immune system may contribute to the disturbance.Our study suggest that the change of micro-environments of thymus induced by SIV infection,which is necessary in T cell and B cell development and differentiation,may contribute at least partially to the AIDS pathogenesis.

OBJECTIVETo investigate the safety, feasibility, perioperational information and post-operational pathology of the modified abdominal operation of extralevator abdominoperineal excision (ELAPE), meaning transpelvic levator dissection under direct visualization.

METHODSFrom January 2010 to March 2013, 36 patients with rectal tumors(≤5 cm distance to anal verge) underwent extralevator abdominoperineal excision with transpelvic levator dissection by laparoscopic or open surgery, without position change during the perineal operation. The preliminary result of this modified technique was summarized.

RESULTSThe levator ani muscles of all the patients were successfully dissected with transpelvic levator dissection and the extent of levator dissection was determined individually according to its involvement. No position was changed during the perineal operation. No conversion to open approach in laparoscopic surgery group was observed, and only 1 case of rectum perforation occurred in open surgery group. The mean operation time was (220.9±36.8) min, and mean intraoperative blood loss was(121.6±99.7) ml. All the specimens had levator ani muscles attached to the mesorectum and positive rate of circumferential resection margin was 5.6%(2/36).

CONCLUSIONSTranspelvic levator dissection simplifies the procedure of ELAPE and achieves individualized dissection of levator. This technique is effective without position change during perineal operation, with shorter operation time and acceptable oncologic outcomes.

OBJECTIVETo explore the risk factors and clinical features of delayed anastomotic fistula (DAF) following sphincter-preserving operation for rectal cancer.

METHODSClinical data of 1 594 patients with rectal cancer undergoing sphincter-preserving operation in our department from January 2008 to May 2015 based on the prospective database of Dpartment of Colorectal Surgery, Fujian Medical University Union Hospital were retrospectively analyzed. Sixty patients(3.8%) developed anastomotic fistula. Forty-one patients (2.6%) developed early anastomotic fistula (EAF) within 30 days after surgery while 19(1.2%) were DAF that occurred beyond 30 days. Univariate analyses were performed to compare the clinical features between EAF and DAF group.

RESULTSDAF was diagnosed at a median time of 194(30-327) days after anastomosis. As compared to EAF group, DAF group had lower tumor site [(6.1±2.3) cm vs. (7.8±2.8) cm, P=0.023], lower anastomosis site [(3.6±1.8) cm vs. (4.8±1.6) cm, P=0.008], higher ratio of patients receiving neoadjuvant chemoradiotherapy (84.2% vs. 34.1%, P=0.000), and receiving preventive stoma (73.7% vs. 14.6%, P=0.000). According to ISREC grading system for anastomotic fistula, DAF patients were grade A and B, while EAF cases were grade B and C(P=0.000). During the first hospital stay for anastomosis, DAF group did not have abdominal pain, general malaise, drainage abnormalities, peritonitis but 8 cases(42.1%) had fever more than 38centi-degree. In EAF group, 29 patients(70.7%) had abdominal pain and general malaise, and 29(70.7%) had drainage abnormalities. General or circumscribed peritonitis were developed in 25(61.0%) EAF patients, and fever occurred in 39(95.1%) EAF cases. There were 13(68.4%) cases with sinus or fistula formation and 9(47.4%) with rectovaginal fistula in DAF group, in contrast to 5 (12.2%) and 5 (12.2%) in EAF group respectively. In DAF group, 5 (26.3%) patients received follow-up due to stoma (no closure), 5 (26.3%) received bedside surgical drainage, while 9(47.4%) patients underwent operation, including diverting stoma in 3 patients, Hartmann procedure in 1 case, intersphincteric resection, coloanal anastomosis plus ileostomy in 1case because of pelvic fibrosis and stenosis of neorectum after radiotherapy, mucosal advancement flap repair with a cellular matrix interposition in 3 rectovaginal fistula cases, incision of sinus via the anus in 1 case. During a median follow-up of 28 months, 14(73.7%) DAF patients were cured.

CONCLUSIONSIt is advisable to be cautious that patients with lower site of tumor and anastomosis, neoadjuvant chemoradiotherapy and preventive stoma are at risk of DAF. DAF is clinically silent and most patients can be cured by effective surgical treatment.
