Objective To discuss clinical efficacy of the modified Stoppa approach in the treatment of acetabular anterior fractures.Methods From January 2011 to December 2014,22 patients with acetabular anterior fracture were treated at our department.They were 14 males and 8 females,with an average age of 36.6 years (range,from 18 to 49 years).By the LetourneI-Judet classification system,there were 9 anterior wall fractures,12 anterior column fractures,and one transverse fracture.The modified Stoppa approach was used for fracture reduction under direct visualization in this cohort.Fixation with reconstruction plate was conducted after satisfactory reduction was confirmed by the X-ray examination.The operative duration,incision length,bleeding volume,fracture reduction quality,function of the affected hip and complications were recorded.Results In this cohort,the incision length ranged from 6 to 15 cm,averaging 9.5 cm;the intraoperative bleeding volume ranged from 100 to 1,000 mL,averaging 550 mL;the operative duration ranged from 40 to 160 minutes,averaging 126.2 min.The 22 patients were followed up for an average of 15.5 months (from 12 to 18 months).According to the Matta imaging evaluation,the fracture reduction was rated as excellent in 18 cases,as good in 3 cases and as poor in one,yielding an excellent to good rate of 95.5％.According to the Harris scoring system,the function of the affected hip was assessed at the final follow-up as excellent in 12 cases,as good in 9 cases,and as poor in one case,giving an excellent to good rate of 95.5％.Traumatic arthritis occurred in one case;there were no such complications as reduction loss or implant failure.Conclusion The modified Stoppa approach is a satisfactory one for the treatment of unstable acetabular anterior fractures,owning to its advantages like minimal invasiveness,simple dissection,excellent visual control of reduction and fixation,and a low rate of complications.

OBJECTIVE:To clarify the bio-transformation form of apigenin in rats,and to speculate its possible metabolic path-way. METHODS:Rats were divided into blank group and medication group(apigenin 200 mg/kg,i.g.)with 6 rats in each group. Urine and feces samples were collected from 2 groups within 24 h after medication. After corresponding treatment,urine and feces samples were analyzed and detected by HPLC-IT-TOF-MSn under cation mode and anion mode. RESULTS:9 metabolites were iden-tified in urine sample of rats from medication group,i.e. 2,3-double bond reduction of apigenin (U1,U7,U8,U9),bonded to glucuronic acid(U2,U3,U4),bonded to sulphate(U5,U6,U7,U8,U9)and bonded to glucose(U2). 4 metabolites were iden-tified in feces sample of rats from medication group,i.e. 2,3-double bond reduction of apigenin(F3),bonded to glucuronic acid (F2)and bonded to glucose(F1). CONCLUSIONS:Apigenin mainly exists in form of prototype drug in rats. The reduction hap-pens on 2,3-double bond by the intestinal bacteria,and the product of apigenin boned to glucuronic acid or glucose can be formed when excreting in intestinal tract and rats in vivo,while the product of apigenin boned to sulphate can be formed only when excret-ing in rats in vivo.

Objective To investigate the merit and feasibility of vasoactive drugs by the double atrial infusion in children with congenital heart disease combined with pulmonary hypertension.Methods Ninety cases of congenital heart disease combined with pulmonary hypertension were randomly selected.One group(45 cases) was infused by double atrialadministration,which left atrium for catecholamines,and right atrial infusion for highly targeted expansion of pulmonary vascular drugs,such as prostaglandin E1.Another group(45 cases) was infused through the right atrium by a central venous to catecholamines and pulmonary vascular dilatation drugs.Cardiac output(CO) and cardiac index were measured by thermal dilution method and systemic vascular resistance and pulmonary vascular resistance(PVR) were calculated.Results Three cases were dead in early postoperative period(1 week),which were central intravenous group.2 cases with total anomalous pulmonary venous drainage had low co after operation,include 1 case through the left atrium,and the other case through central venous administration,and were recovered.There was no long-term mortality.There was no significant difference in CPB time,blocking time,the amount and timing of vasoactive drugs in two groups (P ＞ 0.05).Conclusion Double atrial infusion of vasoactive drugs can significantly reduce the mean pulmonary artery pressure and pulmonary vascular resistance,and increase CO,which is better than the traditional central intravenous methods.The treatment method is of very important significance.Thus double atrial infusion is safe and feasible.

Objective To assess the clinical application value of phleboplasties combined with microvascular anastomotic device in venous anastomosis with diameter discrepancy in head and neck defects reconstruction.Methods Sixty-six pairs of veins with significant diameter discrepancy were anastomosed in head and neck reconstructive surgeries with free flaps.Forty of them were anastomosed with microvascular anastomotic device (the coupler group) after phleboplasties including lateral incision, Y-T enlargement and wedge excision while the other 26 pairs of veins were conventionally sutured (the sutured group).Diameter of each vein, anastomosis time, post-operative vascular crisis, flap survival and complications related to the microvascular anastomotic device were recorded.Results The average anastomosis time of the coupler group was (4.78 ± 1.14) min for lateral incision, (5.16 ± 2.07) min for Y-T enlargement and (11.09 ± 3.21) min for wedge excision, and all of them were significantly shorter than that of the sutured group.In the sutured group, all flaps survived except for 2 veins with poor blood flow were cut and re-anastomosed during the operation;1 flap with venous crisis within 72 hours after the operations was explored and replaced with the pectoralis major myocutaneous flap.All veins in the coupler group were successfully anastomosed in a single coupling procedure without anastomotic impatency, blood leak, vessel tearing and ring shedding.No vascular crisis occurred postoperatively.One patient underwent cervical haematoma 5 hours after the operation, and the flap blood supply was unaffected after the haematoma was removed.All flaps in the coupler group survived completely.Patients in both two groups were followed up 6 to 18 months.All flaps healed perfectly and no obvious surgical complications or microvascular anastomotic device rejection happened.Conclusion When anastomoses are carried out using microvascular anastomotic device between veins of different size, phleboplasties including lateral incision., Y-T enlargement and wedge excision can not only reduce the size discrepancy and the anastomosis time, but also ease the difficulty level and guarantee the patency of the venous anastomoses.Wedge excision enjoys the advantage of haemodynamics, and obstruction of venous reflux hardly occurred for size reduction.It should be considered preferentially when external jugular veins are used as the anastomotic vein of the recipient sites in head and neck reconstruction.
