ObjectiveTo observe the clinical effect of interventional embolization on hepatocellular carcinoma(HCC) with hepatic arterioportal shunts(APS) ,in the hope of improving patients' survival quality and time. MethodsTwenty-nine patients with HCC patients and APS after a successful PVA,steel coils embolization, all patients were given routine TACE therapy. The changes of gastrointestinal bleeding,ascites,diarrhea and aminotransferase were analyzed retrospectively. ResultsNineteen cases got successful embolization in the first time[achievement ratio 65.5％(19/29)]; 3 cases got recurrence after embolization [patency ratio 10.3％(3/29)],7 cases appeared new APS[incidence ratio 24.1％(7/29),5 cases were embolized 2 times, 2 cases were embolized 3 times]. The effective rate of gastrointestinal bleeding,diarrhoea,aacites were 91.7％ (11/12), 84.6％ ( 11/13 ), 83.3％ ( 15/18 ) respectively, which had significant difference between preoperative and postoperative condition. The survival rate of 3 months,6 months, 1 year,and 2 years after operation were 96.6％ (28/29),89.7％ (26/29),65.5％ (19/29),34.5％ (10/29). Conclusion Interventional therapy is a safe and effective treatment to HCC with APS.

ObjectiveTo assess the effectiveness and prognosis of different radical surgery for Hirschsprung disease (HD).MethodsThe bowel function of HD patients undergoing the anus modified Soave operation (84 cases,modified Soave group),modified Swenson operation (60 cases,modified Swenson group),modified Duhamel operation (76 cases,modified Duhamel group) was followed up by 3,6 months and 2 years after surgery.Long-term bowel function,clinical type,removal length,anorectal manometry,barium enema were analyzed and compared among three groups.ResultsThe occurrence rates of bowel dysfunction 3,6 months and 2 years after surgery in modified Soave group[17.9％(15/84),7.1％(6/84),4.8％ (4/84)] were significantly lower than those in modified Swenson group[41.7％ (25/60),21.7％(13/60),18.3％(11/60) ] and modified Duhamel group [ 36.8％ (28/76),18.4％ (14/76),13.2％(10/76) ].There was significant difference between modified Soave group and modified Swenson group,modified Duhamel group(P＜ 0.05 ).There was no significant difference between modified Swenson group and modified Duhamel group (P ＞ 0.05).When the removal length ≤35 cm,the occurrence rate of bowel dysfunction after surgery in modified Soave group [ 18.7％ (14/75)] was lower than that in improved Swenson group [ 39.5％ ( 17/43 ) ] and modified Duhamel group [ 34.4％ (21/61 ) ].There was significant difference between modified Soave group and modified Swenson group,modified Duhamel group (P ＜ 0.05).There was no significant difference between modified Swenson group and modified Duhamel group (P ＞ 0.05).When the removal length ＞ 35 cm,there was no significant difference in the occurrence rate of bowel dysfunction after surgery among three groups (P ＞ 0.05 ).The occurrence rates of bowel dysfunction in short-segment type and common type in modified Soave group was lower than those in modified Swenson group and modified Duhamel group.There was significant difference between modified Soave group and modified Swenson group,modified Duhamel group(P ＜ 0.05).There was no significant difference between modified Swenson group and modified Duhamel group (P＞ 0.05).The anorectal angle 2 years after surgery in modified Soave group [(93.67 ± 10.50)° ] was less than that in modified Swenson group [(110.20 ± 11.88)° ] and modified Duhamel group [(106.33 ± 12.21)° ].There was significant difference (P ＜0.05).ConclusionThe complication and trauma are significantly lower in the anus modified Soave operation than the modified Swenson operation and modified Duhamel operation,but the choice of surgery should be strictly controlled according to the anal HD treatment indications.

Objective To investigate the distribution characteristics and risk factors of intracranial atherosclerotic stenosis ischemic stroke. Methods We retrospectively collected 342 consecutive patients with first-ever ischemic stroke. Clinical data was collected including demographics, the presence of risk factors,MRI with MRA and other routine admis?sion laboratory tests. Results Intracranial atherosclerotic stenosis (ICAS) was located most frequently in MCA (47.0%), Extracranial internal carotid artery was the most common affected artery (65.0%) among extracranial atherosclerotic steno? sis (ECAS). MetS (OR=1.586,95%CI:1.232~2.268), ApoB/ApoA1 ratio (OR=1.926,95%CI:1.051~4.288), were as?sociated with ICAS (vs ECAS), whereas hypertension (OR=3.603,95%CI:1.675~12.485), MetS (OR=2.268,95%CI:1.274~6.103), HbA1c (OR=2.015,95%CI:1.182~5.613) and ApoB/ ApoA I ratio (OR=1.948,95%CI:1.157~4.285) were related to ICAS (vs NCAS). Hypertension (OR=2.437,95%CI:1.492~3.505,P=0.005), Hcy (OR=2.437,95%CI:1.492~3.505,P=0.005) and HbA1c (OR=1.769,95%CI:1.034~3.121, P=0.005) were the independent risk factors re?lated to posterior circulation strokes (vs anterior circulation strokes ) in ICAS strokes. Conclusions The occurrence of ICAS may be more frequent than that of ECAS in ischemic stroke. Posterior circulation ICAS strokes seems to be close?ly associated with metabolic derangement.

Objective To explore any changes in surface electromyogram (sEMG) signals from the lumboabdominal muscles during exercise on stable and unstable surfaces. Methods sEMG signals from the lumbo-abdominal muscles of 33 healthy young persons [18 male and 12 female; average age (26.5 ± 4.3 ) years] were measured with the FlexComp Infiniti apparatus.Each subject performed 5 exercises on and off a Swiss ball:sit,bridge,bridge with both knees flexed,reverse bridge as well as press-up. Results ①In bridging there was a significant increase in the activation of the erector spinae during exercise on the ball compared with on the stable surface.②Bridging with both knees flexed gave a significant increase in activations of the erector spinae,the external obliques and the transverses abdominus/internal obliques during exercise on the unstable surface compared with the stable surface.③During reverse bridging there was a significant increase in activation of the erector spinae and rectus abdominus during exercise on the unstable surface compared with the stable surface.④During press-ups there was a significant increase in activation of the rectus abdominus,the external obliques and the transverses abdominus/internal obliques during exercise on the ball compared with the stable surface. Conclusion The unstable surface provides better training stimulus for the activation of the lumbo-abdominal muscles.

Objective To explore the value of laparoscopy in the diagnosis and treatment of recurrent inguinal hernia in children.Methods The clinical data of 67 cases receiving laparoscopic treatment for recurrent inguinal hernia in children at the Department of General Surgery,Wuhan Children's Hospital,Tongji Medical College,Huazhong University of Science & Technology were retrospectively analyzed,including the type of hernia recurrence,operation time,intraoperative and postoperative complications,such as short-term hydrocele formation and testicular atrophy and so on.Results In 67 cases,there were 65 males and 2 females.Open repair surgery and laparoscopic surgery were respectively performed in 48 cases and 19 cases for the first operation and the hernia defects were found after operation.Contralateral patent vaginal process deformities were found in 11 sides in the reoperation.Among 67 cases of recurrent inguinal hernia,incomplete ligation of hernia sac was found in 21 cases,low level ligation of hernia sac in 17 cases,no ligation of hernia sac in 14 cases,omissive direct inguinal hernia in 4 cases,loose ligation of hernia sac in 4 cases,overlarge inner ring in 4 cases,weak abdominal muscles in 2 cases,and increased abdominal pressure (long-term constipation,asthma) in 1 case.All the patients were treated by laparoscopic hernia repair and no serious complications occurred during the operation.The average time of unilateral operation was (15.0±2.2) minutes (13-25 minutes),and bilateral operation was (27.0±4.3) minutes (18-41 minutes).All patients were discharged on the second day.Two patients showed short-term postoperative hydrocele and were cured with conservative treatment.During the follow-up time of (23±2) months (9-39 months),no recurrence or testicular atrophy was found.Conclusions Laparoscopy can confirm the type of recurrent inguinal hernia and contribute to reduce postoperative recurrence.Laparoscopic management of recurrent inguinal hernia in children is safe and feasible,which is expected to replace open hernia repair.

Objective To evaluate the outcomes of thumb reconstruction with dorsal thumb rotated single pedicel reverse island flap.Methods 49 thumb-tip defects cases with dorsal thumb rotated single pedicel reverse island flap were analyzed retrospectively.37 dorsal thumb reverse island flap were performed,and 12 ulnar-dorsal reverse island flaps were performed.Results The operation time was 40-60 minutes.The mean time was 45 minutes.All 49 cases survived completely.The color of the flaps was purple,and blisters in the surface of the flaps after 1-2 days in 2 cases.After took out stitches partly,the blisters were dried and crusted,the color of the flaps with better blood circulation was normal.The follow-up period was 3-24 months,all thumbs had satisfactory appearances and functions.The two-point discrimination was 6-9mm in flaps inosculated with nerve,that was 8-10 mm in flaps inosculated without nerve.The color,texture and elasticity of flaps were excellent,and the donor sites had not been defected.Conclusion Dorsal thumb rotated single pedicel reverse island flap is a reliable option to restore function as well as appearance,long vascular pedicle with skin strap,wide rotation angle,high rate of survival.It avoided damages to the well-known arteries and nerves.It is a relatively facile procedure that can be applied toward resurfacing thumb tip defects.

PURPOSE: Several signaling pathways have been shown to regulate the lineage commitment and terminal differentiation of bone marrow stromal cells (BMSCs). Bone morphogenetic protein (BMP) signaling has important effects on the process of skeletogenesis. In the present study, we tested the role of bone morphogenetic protein receptor (BMPR) in the osteogenic differentiation of rat bone marrow stromal cells in osteogenic medium (OM) with or without BMP-2. MATERIALS AND METHODS: BMSCs were harvested from rats and cultured in OM containing dexamethasone, beta-glycerophosphate, and ascorbic acid, with or without BMP-2 in order to induce osteogenic differentiation. The alkaline phosphatase (ALP) activity assay and von kossa staining were used to assess the osteogenic differentiation of the BMSCs. BMPR mRNA expression was assessed using reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: The BMSCs that underwent osteogenic differentiation in OM showed a higher level of ALP activity and matrix mineralization. BMP-2 alone induced a low level of ALP activity and matrix mineralization in BMSCs, but enhanced the osteogenic differentiation of BMSCs when combined with OM. The OM significantly induced the expression of type IA receptor of BMPR (BMPRIA) and type II receptor of BMPR (BMPRII) in BMSCs after three days of stimulation, while BMP-2 significantly induced BMPRIA and BMPRII in BMSCs after nine or six days of stimulation, respectively. CONCLUSION: BMSCs commit to osteoblastic differentiation in OM, which is enhanced by BMP-2. In addition, BMP signaling through BMPRIA and BMPRII regulates the osteogenic differentiation of rat BMSCs in OM with or without BMP-2.

Objective Brainstem clinically isolated syndrome (BCIS) may herald multiple sclerosis (MS) or neuromyelitis (NMO),or it may occur as an isolated syndrome.However,the role of anti-aquaporin 4 antibodies in the conversion of BCIS to NMO remains uncertain.Methods Thirty-one BCIS patients hospitalized in our hospital from July 2006 to December 2010 were chosen in our study;their clinical data were retrospectively analyzed;according to the presence of anti-AQP4 antibodies,they divided into two groups:anti-AQP4(+)BCIS group (n=14) and anti-AQP4(-)BCIS group (n=l 7).The differences of clinical manifestations,imaging features and cerebrospinal fluid level between the two groups were compared and the conversion of patients from the two groups was analyzed.Results Nine (64.29％) anti-AQP4 (+)BCIS patients converted to NMO,while only two (11.76％) anti-AQP4 (-)BCIS patients progressed to NMO,over a mean follow-up period of 36.10± 18.94 months;significant difference of conversion rate was noted between the two groups (P＜0.05).Anti-AQP4(+)BCIS patients demonstrated a higher immunogamm globulin (IgG) index (0.68±0.43 vs.0.47±0.19,P=0.018) and Kurtzke Expanded Disability Status Scale (EDSS) scores at the last visit of follow-up 0.64±0.92 vs.2.71±0.81,P=0.000) than anti-AQP4 (-)BCIS patients.Gastroenterology-related brainstem symptoms occurred more frequently in anti-AQP4(+)BCIS patients than that in anti-AQP4(-)BCIS patients (71.43％ vs.23.53％,P=0.001).In brainstem MR imaging,the anti-AQP4(+)BCIS patients were observed having medulla-predominant involvement in the sagittal view (78.57％) and dorsal-predominant involvement in the axial view (78.57％),which were significantly different as compared with those in the anti-AQP4(-) BCIS patients (35.29％ and 41.17％,P＜0.05).Conclusion anti-AQP4(+)BCIS may represent an early,isolated syndrome of NMO spectrum disorder.

Objective To evaluate the efficacy and safety of modified transurethral plasmakinetic enucleation of prostate (M-TPEP) combined with cystolithectomy in elderly patients with high risk of large volume benign prostatic hyperplasia (BPH) complicated with large urinary bladder calculi. Methods Seventy-one patients with high risk of large volume BPH complicated with large urinary bladder calculi were selected, and the patients were treated with M-TPEP combined with cystolithectomy. The operation time, intraoperative blood loss, hospitalization time, complications, and the maximum urinary flow rate (Qmax), post-void residual volume (PVR), serum potassium, international prostate symptom score (IPSS), quality of life (QOL) score preoperative and postoperative 3 months were recorded. Results Seventy-one patients successfully completed the operation, and no death occurred. The operation time was (75.48 ± 6.51) min, intraoperative blood loss was (82.63 ± 10.08) ml, and postoperative hospitalization time was 5-7 d. Incidence of intraoperative capsule perforation was 2.82% (2/71), incidence of postoperative temporary urinary incontinence was 7.04% (5/71), incidence of urethral and bladder irritation after operation was 8.45% (6/71), and incidence of postoperative wound infection was 2.82% (2/71). The PVR, IPSS and QOL score 3 months after operation were significantly lower than those before operation: (6.89 ± 0.74) ml vs. (205.13 ± 40.08) ml, (2.71 ± 0.45) scores vs. (28.62 ± 3.57) scores and (1.36 ± 0.24) scores vs. (4.93 ± 0.38) scores, the Qmaxwas significantly higher than that before operation: (22.46 ± 2.97) ml/s vs. (5.24 ± 0.43) ml/s, and there were statistical differences (P＜0.01);there was no statistical difference in serum potassium between before operation and 3 months after operation (P＞0.05). Conclusions M-TPEP combined with cystolithectomy has short operation time, quick recovery after operation and low complication rate. It is a proper operative method for the elderly patients with high risk of large volume BPH and large urinary bladder calculi.

Objective:To explore clinical results in reconstruction of finger C-shape soft tissue defect with the wrist crease free flap carrying cutaneous nerve.Methods:From June, 2017 to April, 2019, 7 fingers(7 patients) with C-shape defect were treated with the wrist crease free flap carrying cutaneous nerve. The size of defect ranged from 1.0 cm × 2.5 cm-2.2 cm × 4.0 cm; the flap sizes were 1.3 cm × 2.7 cm-2.5 cm × 4.5 cm. Five fingers had unilateral defect of proper palmar digital artery. Two fingers that had bilateral defect of proper palmar digital artery with poor blood circulation were re-established with blood supply by Flow-through flaps. Four fingers had unilateral defect of proper palmar digital nerves, and 3 had bilateral defect of proper palmar digital artery. Five of the fingers were repaired by the superficial branch of the radial nerve and 2 repaired by palmar cutaneous branch of median nerve. Regular outpatient follow-up was conducted after surgery for 8 to 15 (mean 11) months.Results:All the fingers and flaps survived with primary healing. Numbness existed in the areas of functional dominance of the cutaneous nerve. At the end of follow-up, the flaps showed good texture without significant bloated appearance with the recovery of protective sensation. The sensation of fingertip recovered to S 4 in 5 fingers and S 3+ in 2 fingers. Finger pulps were plump. All of the fingers moved freely. Linear scars were observed at donor sites and the wrists moved freely. Numbness feeling in the areas of cutaneous nerve disappeared at 6 to 8 weeks after surgery. According to the Functional Evaluation Criteria of the Finger Replantation published by the Hand Surgery Society of the Chinese Medical Association, the results were excellent in 6 fingers and good in 1 finger. Conclusion:The wrist crease free flap carrying cutaneous nerve is constant and can be dissected transversely to reconstruct and fit the C-shape defect of finger. It can re-establish the blood supply as well as to repair the proper palmar digital nerve defect at the same time.
