Objective To report retrograde transposition of composite tissue flap pedicled with peroneal artery in the treatment of bone and soft tissue defects following calcaneal osteomyelitis.Methods During the period from January 2008 through January 2015,47 patients with bone and soft tissue defects following calcaneal osteomyelitis were treated by retrograde transposition of composite tissue flap pedicled with peroneal artery.They were 43 men and 4 women,aged from 24 to 67 years(average,43.6 years).After radical focus debridement,the areas of skin defect ranged from 2 cm × 2 cm to 5 cm× 5 cm and the bone defects ranged from 1.5 cm × 1.0 cm × 2.0 cm to 3.0 cm × 3.0 cm × 4.5 cm.Results All the 47 patients were followed up for 6 to 72 months (average,25.2 months).Relapse of osteomyelitis occurred in 2 cases but secondary bone graft was needed in none.All the patients recovered their walking function.The texture and color of the composite tissue flaps were similar to those of normal skin,without obvious swelling.The flaps appeared good and imposed no obstacle to wearing shoes.The ankles and hind feet of the patients scored from 58 to 91 points (average,76.6 points) according to the American Orthopaedic Foot and Ankle Society (AOFAS) evaluation system,giving 7 excellent,32 good and 8 fair cases.Hallux flexion contracture without skin ulcer was observed in 10 cases 6 months after surgery,necessitating no surgical intervention.Conclusion Retrograde transposition of composite tissue flap pedicled with peroneal artery can effectively treat bone and soft tissue defects following calcaneal osteomyelitis,leading to a low recurrence rate and good foot appearance.

OBJECTIVE:To establish a method for the content determination of zolpidem tartrate in microsamples of rat plas-ma. METHODS:Rats were given zolpidem tartrate solution 3 mg/kg intragastrically,and 0.2 ml blood sample were collected and isolated. 50 μl plasma was precipitated by methanol,and the supernatant was determined by HPLC-fluorescence combined with ex-ternal method. Agilent HC-C18 column was used with mobile phase consisted of 0.03 mol/L KH2PO4 solution(containing 0.2% tri-ethylamine)-methanol (33∶67,V/V) at flow rate of 1.0 ml/min. The excitation and emission wavelengths were 254 nm and 390 nm,respectively. The sample size was 20 μl. RESULTS:The linear ranges of zolpidem tartrate in plasma was 2-200 μg/L(r=0.999 7),and the limit of quantification was 2 μg/L. The method recoveries of zolpidem were (96.96 ± 1.35)%-(105.0 ± 5.36)%(RSD=2.20%-4.88%,n=5),and extraction recoveries were (79.72 ± 0.01)%-(80.77 ± 0.02)%(RSD=1.34%-3.90%,n=5). The intra-day and inter-day RSDs were 1.40%-5.10% and 3.22%-9.25%(n=5),respectively. CONCLUSIONS:The method is simple,sensitive and suitable for the content determination of zolpidem tartrate in microsamples of plasma.

This paper introduced the management of focus drugs in Ningbo, and evaluated the preliminary results by comparing the changes in terms of the income of these drugs before and after the measures taken. More measures should be taken by establishing a unified drug catalogue, strengthening the assessment, carrying prescription comment and periodic notification. The pharmacists can play a leading role in clinical rational drug use. These efforts can serve for scientific control of the unreasonable growth of medical expenses.

The bursa of Fabricius (BF) is a central humoral immune organ unique to birds. Four bursal peptides (BP-I, BP-II, BP-III, and BP-IV) have been isolated and identified from the BF. In this study, the immunoadjuvant activities of BPs I to IV were examined in mice immunized with H9N2 avian influenza virus (AIV) vaccine. The results suggested that BP-I effectively enhanced cell-mediated immune responses, increased the secretion of Th1 (interferon gamma)- and Th2 (interleukin-4)-type cytokines, and induced an improved cytotoxic T-lymphocyte (CTL) response to the H9N2 virus. BP-II mainly elevated specific antibody production, especially neutralizing antibodies, and increased Th1- and Th2-type cytokine secretion. BP-III had no significant effect on antibody production or cell-mediated immune responses compared to those in the control group. A strong immune response at both the humoral and cellular levels was induced by BP-IV. Furthermore, a virus challenge experiment followed by H&E staining revealed that BP-I and BP-II promoted removal of the virus and conferred protection in mouse lungs. BP-IV significantly reduced viral titers and histopathological changes and contributed to protection against H9N2 AIV challenge in mouse lungs. This study further elucidated the immunoadjuvant activities of BPs I to IV, providing a novel insight into immunoadjuvants for use in vaccine design.
