The compositions and contents of fatty acids in the meat and viscera in Chlamys ferreri near Yantai seacoast, Shandong Province were studied in detail. The result showed that the contents of the unsaturated fatty acids in the meat and wastes were 65. 0% and 66. 2%, respectively. Moreover, the contents of the polyunsaturated fatty acids and EPA+DHA were 55. 1% and 37. 5% in the meat, respectively. The contents in the viscera were 48. 8% and 22. 2%, respectively.

Many controversies and unanswered questions surround AIS(adolescent idiopathic scoliosis),the most difficult one is the absence of information about its aetiopathogenesis.Although bracing has been regarded as the standard of care for patients at a high risk of progression,it has never been subjected to rigorous assessment of either its efficacy or effectiveness.With respect to surgical management,although technology has greatly increased the safety with which we can correct spinal deformity and preserve spinal balance,long-term results of these changing methods of management are absent.Surgery can reduce deformity and prevent further progression;thereby decreasing the risk of future cardiopulmonary compromise,but its role in the prevention of other negative long-term effects of scoliosis is not clear.In this paper we discuss present notions about aetiopathogenesis,natural history,non-operative treatment,and surgery.

Objective To observe the effects of repetitive transcranial magnetic stimulation (rTMS) on cognitive function in rats with chronic cerebral hypoperfusion.Methods The animal model of chronic cerebral hypoperfusion was established in 30 Sprague-Dawley rats by surgically induced bilateral common caroid artery stenosis,who were then divided into a control group and a treatment group.The rats in the treatment group were administered with 20 Hz rTMS 4 weeks postoperation for 7days.Another 10 rat subject to sham operation served as blank controls.The cognitive function was assessed by Morris water maze (MWM) at the time points of 2nd,3rd,4th and 5th days after ending of the 4 weeks of tretment.The morphologic changes of hippocampus neurons were observed with HE staining.The apoptosis was examined by TUNEL,the expression of Bcl-2 or Bax protein was determined using immnunohistochemistry assay.Results At all the time points the MWM escape latency in the rTMS group was shorter than that in the control group (P ＜ 0.01).The percentage of crossing the corresponding platform during the same time period in platform quadrant in the rTMS group was significant higher than that in the control group (P ＜ 0.01).Compared with the control group,the treatment group demonstrated significantly decreased percentage of neuronal apoptosis (P ＜0.05),as well as increased expression of Bcl-2 protein (P ＜0.01) and reduced expression of Bax protein (P ＜ 0.01).Conclusion rTMS can improve the cognitive dysfunction in rats caused by chronic cerebral hypoperfusion,probably through inhibiting neuronal apoptosis in hippocampus region.

Objective:The present study discussed the clinical diagnosis and treatment of pancreatic body and tail carcinoma. Methods:The data of 52 patients with pancreatic body and tail carcinoma treated in Tianjin Medical University Cancer Institute and Hospital from January 2008 to December 2012 were reviewed retrospectively. The data included historical materials of perioperative examination and therapy. The data of 49 cases were reviewed retrospectively, and the median survival was calculated by the Kaplan-Meier method. The effects of the clinicopathologic parameters on the prognosis of patients with pancreatic body and tail carcinoma were examined by the log rank test. Results:Thirty-eight patients underwent exploratory surgery among which 24 had surgical resection, and the standard procedure was distal pancreatectomy plus splenectomy. The tumor staging was stage I in five patients (13.16%), stage II in nineteen patients (50%), stage III in five patients (13.16%), and stage IV in nine patients (23.67%). The median survival time was 18.0 ± 1.23 months for patients who received radical resection and 10.0 ± 2.71 months for patients who underwent nonspecific treatment or palliative therapy. The radical resection was associated with a longer survival period than the nonspecific treatment or palliative therapy (P<0.01). Conclusion:Early diagnosis is the key to achieving long-term survival. The radical resection plays an important role in improving the surgical treatment.

Neurofeedback as a behavior therapy measurement for ADHD has gained increasing attention in recent years.Based on researches have been published of neurofeedback in ADHD in nearly 5 years,the researches development of neurofeedback are reviewed.The data showed that TBR,SMR and SCP neurofeedback are clinically effective treatment for ADHD.Future controlled clinical trials should focus on such known protocols for specific research,and be designed in line with learning theory.

Objective:To assess the analgesic effects and side effects of buprenorphine sublingual tablet in dental treatment.Methods:500 cases for dental treatment were selected.Before management of teeth,all the patients took 0.2 mg of buprenorphine sublingual tablet.The VAS score,Kuttner face score and side effects after dental treatment were recorded.Results:The VAS scores of the patients underwent preventive,operative and prosthetic treatments were 3.99?2.34,2.72?1.67 and 2.78?1.55,the Kuttner scores of those 1.98?1.23,2.66?1.04 and 2.03?0.93,respectively.Side effect was not observed in all the patients.Conclusion:Buprenorphine sublingual tablet can relieve the pain in dental treatment.

A new way is proposed to design control panels of precise titration in infusion.Based on the basic principles of hydrodynamics,this method implements the control of medicine flow by adjusting the tube size.With high precision and low cost,it is beneficial to practical requirements in chinical application.

Sepsis is one of the main cause of patients' death. Lung is the most vulnerable target organ during sepsis, and sepsis patients are often complicated with acute respiratory distress syndrome (ARDS), of which the main mechanism is vascular leakage caused by cytoskeleton rearrangement and cell-to-cell connection changes. IQ-guanosine triphosphatease-activating protein 1 (IQGAP1) has become the key component of cytoskeleton dynamics regulation in recent years. At present, the relationship between IQGAP1 and ARDS induced by sepsis is not yet clear. In this article, we will review the mechanism of the interaction between IQGAP1 and pathogenic microorganisms, changes of pulmonary micro vascular barrier function and cyto-skeleton at the molecular level.
