Objective To investigate the effects of heparin coating on intimal hyperplasia in implanted decellularized xenografts.Methods The resected canie carotid arteries were decellularized,and heparin coating was partially performed.Eighteen rabbits were divided into non-heparin-coated group(n=9)and heparin-coated group(n=9).During implantation,only the left carotid between the anastomotic stoma was ligated.Doppler ultrasonography was performed 1,3 and 12 weeks post-implantation to measure the luminal diameter,and the hemodynamic parameters such as PSV,RI and PI were calculated.All animals were sacrificed,histological observations were conducted at 12 weeks post-implantation,and I/(I+ M)was calculated.Results Except for 1 week post-implantation in the ligated side,the luminal diameters in non-heparin -coated group were significantly smaller than that of pre-implantation.Besides,those of the non-ligated side at each time points were significantly smaller than the ligated side(P

AIM: To investigate the feasibility and clinical effect of punctoplasty by using trabeculectomy punch combined with a novel RS tube for the treatment of punctal stenosis.METHODS: Totally 39 patients (39 eyes) with punctual stenosis were selected from October 2013 to October 2015 in the Second People`s Hospital of Foshan.All patients underwent punctoplasty by using trabeculectomy punch combined with a novel RS tube.These tubes were removed at 3mo after operation.A follow-up of 6mo was taken for final analysis.The fluorescein dye disappearance test score was recorded before the operation and at 1,3 and 6mo after the extubation.The curative effect of the operation at 6mo after the extubation was assess.RESULTS: Fluorescein dye disappearance test: the scores at 1,3 and 6mo after the extubation all decreased compared with the preoperative ones.The difference was statistically significant(P<0.05).At the last following up, 35 eyes (90%) were cured completely, 4 eyes (10%) were improved significantly, no patients recurred.Effective rate was 100%.No serious intraoperative and postoperative complications happened.CONCLUSION: Punctoplasty by using trabeculectomy punch combined with novel RS tubes is a safe and effective method for the punctul stenosis, which is easy to perform, with high success rate.

Objective To observe the clinical effect of neonatal respiratory failure therapy with mechanical ventilation. Methods Forty - eight cases of neonatal respiratory failure were applied endotracheal intubation through mouth. At first, ventilation was given via the intermittent positive - pressure ventilation + peak end - expiratory pressure( IPPV + PEEP) way. Later, the breath parameters were regulated and transited to the intermittent mandatory ventilation( IMV) way according to original illness. When frac - tional concentration of in-spired gas(FiO2)

OBJECTIVE: To test the technical parameters of GlobalFiler® PCR Amplification Kit for its application to forensic application value and to investigate the genetic polymorphisms. METHODS: The validation was conducted in sensitivity, mixed samples, species specificity, adaptability, survivability, consistency, peak height balance and stability. The amplification and detection of the genomic DNA from 373 unrelated individuals from Beijing Han nationality were extracted by automation workstation. RESULTS: Global-Filer® PCR Amplification Kit was adaptive to some mixed, degraded and inhibited samples. The power of sensitivity and adaptability and peak height balance showed well. The distributions of genotype frequencies for 21 STR loci in the population were all in accordance with Hardy-Weinberg equilibrium (P > 0.05). The PIC value of the 21 STR loci was among 0.536 to 0.940; the H value was among 0.558 to 0.933; the DP value was among 0.783 to 0.992; the PE value was among 0.243 to 0.874. CONCLUSION GlobalFiler® PCR Amplification Kit is suitable for criminal cases and DNA database in forensic practice. And 21 STR loci in Beijing Han nationality have high polymorphism, which have application value in forensic practice and population genetics.

OBJECTIVETo explore the effects of electroacupuncture on exercise-induced immunosuppression in rats and its mechanism.

METHODSSports immunosuppressive model was established successfully by the rats were conducted high intensity swimming training 150 min/day, 6 days/wk for 8 weeks in this study. Forty-three SD rats were randomly divided into a control group (group A, n = 10), a high intensity swimming training group (group B, n = 17), and a high intensity plus electroacupuncture group (group C, n = 16). Group A did not receive any intervention. Group B was conducted 150 min/day, 6 days/wk swimming training for 8 weeks. Group C was treated with electroacupuncture at "Baihui" (GV 20), "Guanyuan" (CV 4) and "Zusanli" (ST 36) after every exercise-time from the second week, once each day for 7 weeks. The changes of the rats' weight, gamma-interferon (gamma-IFN), interleukin-2 (IL-2), solubility IL-2 receptor (SIL-2R) and nature killer cell (NKC) were detected.

RESULTS(1) Compared with group A, gamma-IFN and IL-2 in group B were significantly decreased (P < 0.01, P < 0.05), and NKC in group C was significantly increased (P < 0.01). Meanwhile, gamma-IFN and NKC in group C were both significantly higher than that in group B (P < 0.05, P < 0.01). (2) Compared with group A, the weight of the rats in group B and group C were significantly decreased (both P < 0.01), but SIL-2R in group B was significantly increased (P < 0.05). The weight of the rats in group C was significantly higher than that in group B (P < 0.05) and SIL-2R in group C was significantly lower than that in group B (P < 0.01).

CONCLUSIONLasting gravis exercise stress does decrease the immune function in rats and is even inhibited significantly, but electroacupuncture can up-regulate the exercise-induced immunosuppression.

Cervical spondylotic myelopathy (CSM) is a common cause of spinal cord dysfunction clinical disease. Surgery is the main therapeutic tool for CSM. However, there are obvious differences in clinical functional recovery after operation. For the past few years, the influence factors of prognosis in cervical spondylosis myelopathic has been widely concerned. Age, nerve function, course of desease, imaging findings,surgical method and related factors became the investigative point for prognosis of cervical spondylotic myelopathy. Present viewpoint showed that the older patient, preoperative worse nerve function, longer the course of disease would result in worse outcomes. Imaging examination maybe can indicate the prognosis, but the correlation is unclear. Selection of surgical method and approach should be based on the principles of sufficient decompression, stabilize the alignment of the cervical spine, keeping backward extension of cervical spine, maintain effective decompression, preventing complications. Therefore, the treatment of cervical spondylotic myelopathy should be on the basis of pathogenic condition and imaging examination at early stage and a suitable usrgical procedure should be performed to obtain a better prognosis.

Objective To investigate the MR features of pituitary abscess.Methods The MR features of 14 cases of pituitary abscess proved by surgical pathology and clinical treatments were analyzed retrospectively.Results Pre-contrast MR showed hypointense heterogeneous intensity on T_1 WI in 12 cases and iso-hyperintense on T_1 WI in 2 cases,hyperintense on T_2 WI in all cases.Post-gadolinium MR showed the ring-like enhancement around the uneven edge of abscess and the surrounding enhanced meninges connecting to the focus.The normal pituitary could not be identified in all 14 cases.The MR specific findings include the fluid-fluid level,nodule on the edge and the enhanced patchy shadow.Conclusions The pituitary abscess has specific findings on MR examination,which can be used to combine with clinical symptoms to achieve the diagnosis before operation,so that the cases could be treated with antibiotic without operation.

The present investigation was undertaken in order to select the surface-sterilization technique most efficient for eliminating epiphytes, to document endophytes of healthy tissues from Glaycyrrhiza inflat Bat. in Xinjiang. Surface sterilization with 5% commercial solution of sodium hypochlorite for 5 minutes was reaffirmed as adequate for removing epiphytes on licorice roots. From the 151 segments incubated, 149 bacterial isolates and 2 fungal isolates were obtained. From all the isolates, Bacterial isolates were identified by VITEK-AMS. Part of Bacteria were identified in 13 different genus. Fungal species were characterized as Penicillium sp. and Fusarium sp.with microscope.
