BACKGROUND:Currently a big controversy erupts in the repair of abdominal wal defects with composite patch. OBJECTIVE:To compare the composite patch and biological patch in the repair of abdominal wal defects in dogs. METHODS:Ten dogs were selected to prepare abdominal wal defect models, and then randomized into experimental group subjected to composite patch repair and control group subjected to biological patch repair. Incision adhesion was assessed at postoperative 30, 60, 90 days; patches and defect tissues were taken and detected histologicaly at postoperative 14 days. RESULTS AND CONCLUSION:The incision adhesion in the experimental group was milder than that in the control group at different time post operation (P < 0.05). At 14 days post operation, the material structure was clear with no signs of absorption in the experimental group, and there were a large amount of infiltrated inflammatory cels around the patch material, such as neutrophils and lymphocytes, and non-phagocytic patch was found; in the control group, the material structure was fuzzy with the presence of inflammatory cel infiltration and slight signs of absorption. Moreover, inflammation and fibrosis were severer in the control group than the experimental group. These findings indicate that compared with the biological patch, the composite patch is better to effectively reduce inflammatory reactions.

Laser-induced breakdown spectroscopy has become a very attractive technique in the field of chemical analysis.The technique utilizes a laser focused on a small spot to create a micro-plasma on the sample surface.In recent years, laser-induced breakdown spectroscopy (LIBS) is a frontier analysis technique in spectrometric analysis, with the advantages such as real-time, online and non-contact analysis.The research and development of various instruments based on this technology has attracted great attention of researchers.In the article, we reviewed the research progress of LIBS instrument from the components and field equipment in recent years, mainly including portable LIBS, handheld LIBS and remote LIBS.

Despite the immense achievement in the field of IVF in recent years, many patients still suffer from recurrent implantation failure. Therefore, much attention has been drawn to its etiology and treatment. Chromosomal abnormality, sperm DNA damage, zona hardening, and inappropriate culture conditions are important factors that lead to recurrent implantation failure. Results of studies suggest that preimplantation genetic screening does not improve the rate of implantation or live birth. Comparative genomic hybridization array and single nucleotide polymorphism array could offer a more comprehensive screening of chromosomes. Assisted hatching may help to solve the problem of zona hardening in some situations. Co-culture and blastocyst transfer could be conducive to the improvement of the rates of implantation and pregnancy. Cytoplasmic transfer may give a solution to ooplasmic composition anomalies.

[Summary] Limb numbness is a common symptom of diabetic peripheral neuropathy(DPN),which is similar to lumbar vertebra disease and spinal cord tumor compression syndrome. Diabetes mellitus (DM) combined with lumbar spondylosis and spinal cord tumor compression is rarely occurred and is difficult to distinguish from DPN . Here we reported a case of DM combined with spinal neurilemoma that was misdiagnosed as DPN for half a year.

Objective To research the best extracting technology of simiaoyongan decoction.Methods As the total contents of chlorogenic acid and harpagoside to be evaluation indicator, adopted L9 (34 ) orthogonal design to select out the best extraction.The main determination was by HPLC method.Results Accounted by the total contents of the two composi-tions, the influential effects of the experimental results were extraction solvent >reflux times >the volume of extraction>the circumfluence time.Conclusion The best extracting technology is adding 10-fold times of 50% alcohol, percolating 1 hours, and three times.

Objective To evaluate the clinical value of CT three-dimensional(3-D) imaging on diagnosing of bone and joint diseases.Methods The imaging findings of 357 cases proved by operation or clinic were analyzed retrospectively by the 3-D imaging.The diagnosis accuracy of 3-D imaging was compared with that of routine CT.3-D images were obtained by surface shade display(SSD),multi-planar reconstruction(MPR),maximum intensity project(MIP) and volume rendering(VR).Results In 357 patients,257 cases were traumatic disease,100 cases were non-traumatic disease.The diagnosis accuracy of 3-D imaging was 98.3%,which was higher than that of routine CT(P

Objective To explore the effect of early neuromuscular electrical stimulation (NMES) combined with sour taste therapy on dysphagia in the oral phase of acute/subacute ischemic stroke patients. Methods From January, 2013 to June, 2015, 90 patients with oral phase dysphagia after stroke were randomly assigned into NMES group (NM group), sour taste group (ST group ) and NMES combined with sour taste group (TO group) with 30 patients in each group. The swallowing function was evaluated with Functional Oral Intake Scale (FOIS) at baseline, three weeks and twelve weeks treatment. Results The change of FOIS was better in TO group than in ST group three weeks after treatment (P<0.01), and was better in TO group than in ST group and NM group twelve weeks after treatment (P<0.05). Conclu-sion An early application of NMES combined with sour taste therapy could improve the swallowing coordination, and reduce the the poten-tial complications in oral phase of acute/subacute ischemic stroke patients with dysphagia.

Objective To study the effects of the pediatric sinusitis patients using furoic acid momethasone nasal spray after the treatment.Methods 60 pediatric sinusitis patients were divided into the two groups by the random number table method,gien the control group conventional treatment,and the observational group furoic acid momethasone,pediatric sinusitis nasal spray treatment,then the clinical effect and safety of the two groups of children were observe dand compared.Results After the treatment of the two groups,the observational group total effective rate(96.67%)was significantly higher than that of the control group (70.00%)(χ2 =10.23,P <0.05 ),the incidence of adverse reactions(3.33%)in children with significantly less than the control group(33.33%),which was statistically significant (χ2 =12.48,P <0.05 ).The observational group with bacterial clearance rate was significantly higher than that of the control group(90.91%)in children with bacterial clearance rate(61.90%), which was statistically significant(χ2 =13.26,P<0.05).Conclusion Using mometasone furoate nasal spray in the treatment of sinusitis in children can improve the total efficiency,and with low incidence of adverse reactions,which can effectively improve the clearance rate of bacteria,beneficial to restore the health of children,safe and effective and should be widely used in clinical practice.
