BACKGROUND:Basic fibroblast growth factor can promote angiogenesis and connective tissue regeneration, but it can be degraded rapidly in vivo. Fibrin glue as a carrier can play a slow-release effect against the rapid degradation of basic fibroblast growth factor, so as to better play the biological role of basic fibroblast growth factor. But at present, the concrete application of them is stil in the research stage. OBJECTIVE:To review the research progress of the application of basic fibroblast growth factor and fibrin glue in orthopedics. METHODS:The recent literature concerning the application of basic fibroblast growth factor and fibrin glue in orthopedics was extensively reviewed by the first author through a computer-based retrieval of CNKI and Medline databases (2000-2014). RESULTS AND CONCLUSION:Finaly 64 articles were included in result analysis. Basic fibroblast growth factor can promote wound healing and tissue repair with the fibrin glue used as a carrier, but most studies are stil in the experimental stage and its clinical application needs further study.

BACKGROUND:An ideal animal model is important for studying gouty arthritis. However, a lack of perfect animal model of gouty arthritis delays the progress in searching for a novel drug and treatment method. OBJECTIVE:To evaluate the effectiveness of the modified rabbit model of gouty knee arthritis. METHODS:New Zealand white rabbits were selected and randomly divided into four groups. Except bIank control group received no intervention;the rabbit greater omentum was removed, which was wrapped with nothing (sham operation group), impIanted with 0.1 g/L monosodium urate crystal suspension (conventionaI group), or 100 mg/kg monosodium urate crystal (modified group) into the suprapatellar cyst of the rabbit right knee. The swelling degree, motor function, and inflammatory response of the knee joint were observed at 1, 2 and 3 days, 1, 2, 3, and 4 weeks after modeling to evaluate the advantages and disadvantages of the modified model. RESULTS AND CONCLUSION:The movement function in the modified group was significantly decreased within

Objective To investigate the expression of basic fibroblast growth factor(bFGF) and proapoptotic gene Bax,Bcl-2 in amniochorion and their relationship with premature rupture of membranes(PROM).Methods Immunohistochemical stain was used to detect the expression of bFGF,Bax and Bcl-2 in amniochorion collected from 30 pregnant women with PROM and 30 normal pregnant women without PROM.Results The expression of bFGF and Bax were located in the plasma of all types of cells including trophoblast,epithelial,mesenchymal and fibroblast,but the expression of Bcl-2 was only observed in the chorionic syncytiotrophoblast;the positive average integral calculus oculus dehtor of bFGF in the PROM group was significantly lower than that of the normal group(0.051?0.012 vs 0.098?0.027,P0.05).Negative correlation was found between the bFGF and Bax expression in the PROM group(r=-0.616,P0.05). Conclusions The reduced expressions of bFGF and excessive apoptosis in the amnio-chorion play an important role in PROM.

Objective To investigate the effects of dexmedetomidine preconditioning on nitric oxide (NO)/endothelin (ET)-1 imbalance and remote lung injury induced by lower limb ischemia-reperfusion (LIR). Methods Sixty patients who scheduled for unilateral lower extremity surgery matched American Society of Anesthesiologists (ASA) Ⅰ-Ⅱ, were randomized into two groups:control group (R group, n=30) and dexmedetomidine preconditioning group (PD group, n=30). Lumbar plexus combined with sciatic nerve block was performed guided by a nerve stimulator in both groups. In group PD, dexmedetomidine intravenous infusion was started at a dose of 0.125 mL/kg (4 mg/L) for 10 minutes before using tourniquet, whereas group R received an equivalent volume of normal saline. Artery blood gas analysis, respiratory index and oxygenation index were measured, and NO, ET-1, interleukin-8 (IL-8) and malondialdehyde (MDA) concentrations were determined from plasma samples 10 minutes before tourniquet inflation (T0), 15 minutes (T1), 2 h (T2), 6 h (T3) and 24 h (T4) after tourniquet deflation. Results Compared with T0, RI was higher at T3 in group R and OI was lower at T2-4 (P＜0.01). There were no significant differences in RI and OI of group PD between different time points (P＞0.05). In R and PD groups, ET-1, IL-8 and MDA concentrations were increased, while NO level and NO/ET-1 ratio were significantly decreased after tourniquet deflation (P＜0.05). Compared with group R, RI was lower and OI was higher at T3 in group PD (P＜0.01). The levels of ET-1, IL-8, MDA, NO and NO/ET-1 ratio were significantly different after tourniquet deflation between group PD and group R (P＜0.05). In group R, there was positive correlation between ET-1 and IL-8 levels with RI, and negative correlation between ET-1 and IL-8 levels with OI (P＜0.01). There was positive correlation between NO level, NO/ET-1 ratio and RI level (P＜0.01). Conclusion Lung function impairment induced by tourniquet application could be attenuated by dexmedetomidine preconditioning based on protecting endothelial cells and inhibiting lipid peroxidation.

Polypoidal choroidal vasculopathy(PCV) is a common disease of the retina,the disease is more found in colored race.In China,the mainly nosogenic population is the female about 60 years old.The pathogenesis of PCV is unknown and there is no specific medicine at present.The funduscopic present is orangered lesions,bleed and exudation.Indocyanine green angiography(ICGA) could make a definite diagnosis of PCV.In recent,the main treatment of PCV includes photodynamic therapy,intravitreal anti-VEGF therapy,surgery for treatment of complications and combined therapy.We review the treatment and diagnosis of PCV,and propose the further research direction.

Objective To retrospectively review the diagnosis and treatment of intraarticular synovial hemangioma of the knee under arthroscope. Methods Six cases of intraarticular synovial hemangioma of the knee were included. The examination of X ray and MRI before surgery indicated intraarticular synovial hemangioma in 5 cases and pigmented villonodular synovitis in 1 case, then arthroscopic diagnosis and excision of the lesions were followed. Results The six cases were definitely diagnosed as intraarticular synovial hemangioma. Under arthroscope, the lesions exhibited as irregular dark blue or purple capillary clumps of different sizes. The postoperative follow-up of 10.7 months in average (range 4-23 months) shows good joint function for all the patients and no signs of recurrence at the last follow-up. Conclusion Intraarticular synovial hemangioma is rare with a high rate of misdiagnosis. Careful physical examination and MRI can help to make the diagnosis. Arthroscopic surgery is a choice of diagnosis and treatment for intraarticular synovial hemangioma of knee.

Objective To investigate the clinical efficacy of allogeneic cross-linked dermal dressing (ACLD) for the treatment of enteroatmospheric fistula (EAF) in patients with open abdomen (OA).Methods The clinical data of 44 patients with experienced trauma who received OA at Nanjing General Hospital of Nanjing Military Command from January 2011 to January 2014 were retrospectively analyzed.All patients received temporary abdominal closure (TAC) by modified sandwich-vacuum package (MSVP).From January 2011 to December 2012,33 patients with OA received vaseline gauze as abdominal cover layer (VG group),and from January 2013 to January 2014,11 patients with OA received allogeneic cross-linked dermal dressing as abdominal cover layer (ACLD group).Patients were followed up via outpatient examination or telephone interview till October 2014.The incidence of EAF,time for skin-grafting,hematologic indexes in 2 weeks after surgery (white blood cell counts,percentage of neutrophil,the mean value of procalcitonin and C reactive protein),the duration of postoperative hospital stay,hospital expenses and survival rates in the 2 groups were analyzed using t-test,repeated measures analysis of variance and Fisher's exact test.Results The incidence of EAF in the VG group and ACLD group was 42.4％ (14/33) and 0,respectively,with a significant difference between the 2 groups (P ＜ 0.05).The duration of skin-grafting was (15 ±6) days in the VG group and (11 ±3)days in the ACLD group,with a significant difference between the 2 groups (t =2.10,P ＜ 0.05).The mean values of preoperative procalcitonin and postoperative procalcitonin at day 1,3,7,14 in the VG group were (1.20 ± 0.60)pg,/L and (2.50-± 0.90)pg,/L,(1.70 ± 0.30) pg/L,(1.90 ± 0.40) μg/L and (2.70 ± 0.60) μg/L,which were significantly higher than that of (0.90 ± 0.30) μg/L and (1.80 ± 0.60) μg/L,(1.30 ± 0.50) μg/L,(0.60 ± 0.20) μg/L and (0.30 ± 0.07) μg/L in the ACLD group (F =8.50,P ＜ 0.05).The white blood cell counts and percentage of neutrophil and the percentage of C reactive protein between the 2 groups were changed from (13.8 ±2.4) × 109/L,(12.9 ± 2.1) × 109/L,0.90±0.09,0.88 ±0.06,(81 ± 19)mg/L,(136 ±28)mg/L to (16.2 ±3.3) × 109/L,(7.9 ± 3.0) x 109/L,0.85 ±0.12,0.79 ±0.09,(131 ±30)mg/L,(59 ±22)mg/L at postoperative day 14,showing no significant difference between the 2 groups (F =3.10,0.50,1.20,P ＞ 0.05).Duration of hospital stay and hospital expenses in the VG group and ACLD group were (137 ±32)days,(638 831 ± 113 670) yuan and (82 ± 44)days,(474 839 ± 78 543)yuan,respectively,with a significant difference between the 2 groups (t =3.60,4.43,P ＜ 0.05).The time of follow-up and overall survival rate in the VG group and ACLD group were 29 to 38 months and 81.8％ (27/33),and 10 to 20 months and 90.9％ (10/11),respectively,with no significant difference (P ＞ 0.05).Conclusion Allogeneic cross-linked dermal dressing as abdominal cover layer can effectively decrease EAF in patients with open abdomen.
