Objective To investigate the levels of serum vascular endothelial growth factor(VEGF) and basic fibroblast growth factor(bFGF) in patients with non-small cell lung cancer(NSCLC) and relationships with c1inicopatho1ogica1 characteristics and their clinical significance. Methods The concentrations of serum VEGF and bFGF were detected by enzyme-linked immunosorbent assay(ELISA) in 40 patients with NSCLC before and after chemotherapy. Results The level of serum VEGF in patients with Ⅳ stage NSCLC was significantly higher than that of Ⅲ stage(P

OBJECTIVETo investigate the effect of peroxisiome proliferator activated receptor-α (PPAR-α) on the regulation of cardiomyocyte hypertrophy and the relationship between the effect of PPAR-α with PI3K/Akt//mTOR signal pathway.
METHODSCardiomyocyte hypertrophy was induced by isoproterenol (ISO). The cell surface area was measured by image analysis system (Leica). The expressions of atrial natriuretic peptide (ANP), β-myosin heavy chain (β-MHC) and PPAR-α mRNA were detected by qRT-PCR. The protein expressions of Akt, mTOR and P70S6K were detected by Western blot. The expression of PPAR-α was suppressed by RNAi.
RESULTS(1) The expression of PPAR-α was significantly reduced in cardiomyocyte hypertrophy. PPAR-α activator Fenofibrate (Feno) increased the expression of PPAR-α and suppressed cardiomyocyte hypertrophy. The inhibitory effect of Feno on cardiomyocyte hypertrophy was reversed by PPAR-α RNAi. (2) Feno significantly inhibited the increase of the protein expressions of p-Akt, p-mTOR and p-p70S6K in ISO induced cardiomyocyte hypertrophy, which could be blocked by PPAR-α RNAi. (3) PI3K antagonist LY294002 (LY) or mTOR antagonist rapamycin (RAPA) markedly-inhibited cardiomyocyte hypertrophy. The inhibitory effects of LY or RAPA on cardiomyocyte hypertrophy were reversed by PPAR-α RNAi.
CONCLUSIONPPAR-α can negatively regulate cardiomyocyte hypertrophy. The effect might be associated with PPAR-α inhiting PI3K/ Akt/mTOR signal pathway.

Burn patients often suffer from different degrees of dysfunction, such as residual burn wounds, formation of hyperplastic scar, scar itching, cardiopulmonary dysfunction, limitation of motion, and psychological disorders, which exert severe impact on their daily life. This article reviews various rehabilitation treatments for dysfunction after burn injury to promote rehabilitation of burn patients.

Objective To explore the clinical characteristics ,diagnosis, treatment and prognosis of phaeohyphomycosis. Methods Clinical data were collected, including history, physical examination, cranial and spinal imaging. Brain biopsy was performed. Data of the pathology and incubation of brain tissue were analyzed. Responsiveness to treatment was followed up. Results A previously healthy three and half years old boy was presented to our unit, with a three- month history of recurrent headache, vomiting, progressive paraplegia accompanied by urinary continence and constipation. A computed tomogram scan and magnetic resonance imaging of the brain revealed multiple lesions located in the region of the parietal - occipital lobes, periventricular area and frontal lobe, with prominent surrounding edema and irregular peripheral enhancement of the mass after the administration of contrast materials. A cerebral biopsy was performed and the pathological report was cerebral phaeohyphomycosis. The culture of the tissue and cerebrospinal fluid grew a same fungus identified as exo-phiala dermatitidis. The patient's response to therapy was poor, the parents of the boy gave up therapy, and the boy died 1 month later. Conclusions Cerebral Phaeohyphomycosis caused by Exophiala dermatitidis is rare, but the most serious form of fungus infection. Pathology and incubation of the tissue are essential for diagnosis. There is no curative therapy and the prognosis is poor.

Objective To explore whether chlamydia pneumoniae(CP) infection causes the coronary artery morphology change in children and their reciprocity.Methods Serum immunoglobin M(IgM) and immunoglobin G(IgG) antibody to CP were detected by enzymelinked immunosorbent assay(ELISA) in 52 hospitalized children aged 1 month to 10 years and 5 months old in respiratory ward in our hospital,serum interleukin-6(IL-6),triglyceride(TG) and peripheral blood C-reactive protein(CRP) were also determined,morphology change of coronary artery of the patients were harvested by colored doppler echocardiogram.Results In the 52 cases,21 cases were positive of IgM,28 cases were positive of IgG,3 cases were positive both IgM and IgG.Twelve cases were high of CRP,5 cases were high of IL-6,9 cases were high of TG.In the 52 patients,the different levels of IgM,IgG,IL-6,CRP and TG had not coronary artery morphology change.Conclusion CP infection in the children does not cause the coronary artery to occur morphology change.

OBJECTIVETo detect the methylenetetrahydrofolate reductase(MTHFR) gene C677T mutation with molecular beacon technique and assess the revant applicability.
METHODSA total of 228 samples were analyzed using molecular beacons which are oligonucleotide probes to become fluorescent upon hybridization. Wild-type molecular beacon and mutant beacon were designed to detect the genotypes of MTHFR gene.
RESULTSAnalysis of the 228 samples indicated that there were three genotypes including 41 homozygous mutants, 113 heterozygous individuals and 74 wild-type individuals. Every sample was identified clearly.
CONCLUSIONThe present method, a closed-tube PCR/hybridization assay, is a simple, high-throughput and fast procedure that is fully automated for detecting gene mutation.

OBJECTIVETo analyze the incidence, clinical features, deformity categories and orthopedic treatment of foot and ankle deformities caused by spinal bifida.
METHODSThe charts of the patients received surgical treatment between January 1990 and July 2009 were studied retrospectively, and the data were analyzed.
RESULTSOne hundred and seven cases of foot and ankle deformities caused by spinal bifida received surgical treatment and were included. There were 44 male and 63 female patients. The average age was 17.7 years (range, 1.3 - 52.0 years). And 50.5% (54/107) of cases were over 18 years old and had spinal bifida occulta, and the other 49.5% had spinal bifida manifesta. There was only one case of thoracic spinal bifida (T(3-8)), while the other 106 cases had lumbosacral vertebrae cleft (mainly L(3) to Sacrum). Among a total of 165 feet, unilateral involvement was found in 49 cases (22 cases on the left side, 27 cases on the right side), bilateral involvement in 58 cases. Combined ankle-foot deformities included 76 varus talipes, 23 talipes valgus, 15 flail feet, and 51 other foot deformities. Other site deformities, as a result of spinal bifida, included knee flexion or hyperextension deformity in 4 cases, hip deformity (hip adduction, flexion, or hip dislocation, pelvic tilt, lower extremity discrepancy, etc.) in 17 cases, and urinatory dysfunction and defecation in 30 cases. Twenty-nine of 54 cases with spinal bifida occulta failed to be diagnosed in other hospitals and the misdiagnosed rate reached 53.7% (29/54). Corrective surgery was performed in only 26 patients. And 50.5% (54/107) of patients (over 18 years old) had severe foot and ankle deformities due to a failure of prior surgical treatment.
CONCLUSIONSSpinal bifida is the most commonly found in the lumbosacral vertebrae. Although the main pathogenesis is developmental abnormalities of spinal cord and nerve, the secondary deformity is usually located on the foot and ankle. Some young orthopedic surgeons may not have enough awareness and treatment experience about this disease due to over-specialty of the orthopaedics, so the delay of early diagnosis and treatment is often found and many severe foot and ankle deformities occur.
