Objective To describe our experience and method of reconstruction after resection of tumors around inner canthus and nasion in the elderly. Methods The line between outer and inner canthus was considered during reconstruction.If the surface of wound after resection was above this line,glabellar flap was used to reconstruct the upper part and the residual defect was repaired with advancement of lower eyelid and rotation of flap.If the surface of wound was below this line,lower eyelid flap was used and the residual defect was reconstructed with glabellar flap. Results All flaps survived without any significant complications.9 cases among 15 patients were followed up from 1 to 24 months.Repaired tissues all matched well with surrounding tissue in color,texture,and outline.Eyelid and medial canthal were not disturbed and there was no tumor recurrence.Scars were smoothy,soft and hidden with satisfactory appearance and vision. Conclusions Single local flap or combined local skin flaps around the nasion and inner canthus is one of reconstruction methods to get satisfactory cosmetic effect or facial morphology.

The high molecular weight glutenin subunits (HMW-GS) are the main components of storage proteins of wheat,and play a critical role in determining the visco-elastic properties of gluten. There are both quantitative and qualitative effects of HMW-GS on the processing properties of wheat. Current knowledge of the molecular structures,compositions and properties of the gluten proteins of wheat is summarized in details,and the role of the HMW-GS in determining the quality of the grain for breadmaking and how their amount and composition can be manipulated leading to changes in dough mixing properties is also discussed systematically.

ObjectiveTo determine the effect of telmisartan on the levels of serum adiponectin and C-reactive protein(hs-CRP)in elderly hypertensive patients with unstable angina pectoris. MethodsOne hundred and twenty elderly hypertensive patients with unstable angina pectoris were randomized into two groups, telmisartan(n=60) and perindopril(n=60) groups.The levels of hs-CRP,adiponectin, lipid factors, fasting plasma glucose (FPG), insulin and insulin sensitivity index (ISI) were measured before and 6 months after telmisartan and perindopril treatments.ResultsAt the end of 6 months, the telmisartan group showed more reduction in plasma levels of hs-CRP and more increment in serum adiponectin concentrations and ISI significantly. The frequency of cardiovascular events was significantly lower in the patients of the telmisartan group than that of the perindopril group.ConclusionsCompared with perindopril, telmisartan significantly decreases plasma levels of hs-CRP and increases serum adiponectin concentrations in elderly hypertensive patients with unstable angina pectoris. It also significantly decreases the frequency of cardiovascular events in these patients.

Hematopoietic stem/progenitor cell transplantation is one of main choices for treating patients with malignant tumor or heredity diseases in recently year. The homing of hematopoietic stem cells(HSC) is a committed step to ensure the bone marrow hematopoiesis reconstitution. Recent studies have showed that stromal cell derived factor-1 (SDF-1) and its receptor has important effects on proliferation, differentiation, homing of HSC to bone marrow and hematopoiesis reconstitution. The purpose of this review is to give a recent update informations on mechanism of hematopoiesis regulation mediated by SDF-1 and its receptor

Objective To evaluate the feasibility of modified lateral approach to sciatic nerve block guided by ultrasound and nerve stimulator for foot surgery.Methods Sixty-two patients of both sexes,aged 18-60 yr,with body mass index ＜ 30 kg/m2,of ASA physical status Ⅰ-Ⅲ,scheduled for elective foot surgery,were included in the study.Anesthesia was induced with iv propofol 2-4 mg/kg and sufentanil 0.2-0.4 μg/kg.The laryngeal mask airway was inserted and the patients were mechanically ventilated.Sevoflurane was inhaled continuously.Modified lateral approach to sciatic nerve block was performed with 0.3 ％ ropivacaine 30 ml under the guidance of the ultrasound combined with nerve stimulator.Rocuronium 0.6 mg/kg and propofol 1-2 mg· kg-1 · h-1 were administered after completion of sciatic nerve block.Additional sufentanil 0.10-0.15 μg/kg was intravenously injected immediately after skin incision and rocuronium 0.15 mg/kg was injected intravenously at 1 h intervals.The depth of puncture and time for puncture and success rate of puncture were recorded.Sensory block was assessed after the patients regained consciousness completely.Nerve injury,hematoma at the puncture site and infection within 72 h after surgery were recorded.Results The time for puncture was (40 ± 17) s.The depth of puncture was (5.8 ± 0.7) cm.The success rate of puncture at first attempt was 77 ％.The rate of complete sensory block was 100％.The post-operative follow-up showed that no patients developed nerve injury,hematoma or infection.Conclusion Modified lateral approach to sciatic nerve block guided by ultrasound and nerve stimulator is safe and effective for foot surgery.

Objective To evaluate the efficacy of lateral femoral approach to continuous sciatic nerve block for patient-controlled analgesia after foot and ankle surgery.Methods One hundred American Society of Anesthesiologists physical status Ⅰ-Ⅲ patients of both sexes,aged 18-60 yr,weighing 50-100 kg,with body height of 145-190 cm,scheduled for elective foot and ankle surgery,were divided into 2 groups (u =50 each) using a random number table:patient-controlled nerve block analgesia (PCNA) group and patient-controlled intravenous analgesia (PCIA) group.In group PCNA,the lateral femoral approach to sciatic nerve block was performed under the guidance of ultrasound and a neurostimulator,0.2％ ropivacaine 20 ml was injected after successful location,the catheter was inserted,and 0.2％ ropivacaine 10 ml was injected again.In group PCIA,0.2％ ropivacaine 30 ml was injected after successful location of the sciatic nerve.General anesthesia was performed using laryngeal mask airway in both groups.In group PCNA,PCNA was performed with 0.2％ ropivacaine (diluted to 200 ml in normal saline) at the end of surgery,and the PCNA pump was set up with a 0.5 ml bolus dose,a 15-min lockout interval and background infusion at a rate of 5 ml/h.In group PCIA,PCIA was performed with sufentanil 100 μg,tramadol 500 mg and tropisetron 10 mg (diluted to 200 ml in normal saline) at the end of surgery,and the PCIA pump was set up with a 0.5 ml bolus dose,a 15-min lockout interval and background infusion at a rate of 2 ml/h.The visual analog scale score was maintained≤ 3,and postoperative analgesia lasted until postopera-tive 72 h.When visual analog scale scores ≥ 4,tramadol 100 mg was intramuscularly injected as rescue analgesic.The requirement for rescue analgesia and development of adverse effects such as nausea and vomiting,insomnia,puncture site infection and bleeding were recorded within 72 h after surgery.Results The requirement for rescue analgesia and incidence of nausea and vomiting were significantly lower in group PCNA than in group PCIA (P＜ 0.05).Conclusion The lateral femoral approach to continuous sciatic nerve block can be safely and effectively used for patient-controlled analgesia after foot and ankle surgery.
