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.

Objective To learn about the mastery level of midwives and obstetric nurses about fetal monitoring knowledge.Methods 77 midwives and obstetric nurses attending a fetal monitoring education programme in Huaxi Second Hospital of Sichuan University were investigated by using a self-made questionnaire.Results Some respondents lacked of systematic training in fetal monitoring knowledge,and they could not accurately answer the purpose or contents of fetal monitoring,as well as the basic elements and related knowledge about fetal electronic monitoring.Most of the respondents focused on fetal monitoring in clinical practice,but neglected the corresponding frontier progresses.Conclusions The training and education on fetal monitoring knowledge should be strengthened to improve obstetric quality because of the unsatisfactory survey results in midwives and obstetric nurses.

Serious and/or continuous cerebral hemodynamics disorder is the main cause of neonatal brain injury.Monitoring its changes by using simple,accurate and effective techniques has guiding significances in maintaining the stability of neonatal cerebral hemodynamics.This paper aims to introduce several cerebral hemodynamic monitoring techniques,including color Doppler ultrasound,near infrared spectroscopy,noninvasive magnetic resonance imaging,and provide references to the clinical application in neonatal field.

Post-operative pancreatic fistula(POPF)is the most common and severe complication after pancreaticoduodenectomy,which may have significant impacts on curative effects and prognosis.It has been shown that POPF is not only closely associated with texture of pancreatic parenchyma,diameter of pancreatic duct and tumor site,but also affected by surgeon's experience and surgical techniques.Double layer pancreaticojejunostomy and external pancreatic duct stent may be beneficial to decrease POPF.

Objective To investigate the clinical value of the optical microscope on the quality control of the coagulation specimen microscopic examination before the coagulation test.Methods 92 patients with coagulation specimens agglutination occurs which taken were selected as the experimental group,92 patients re-blood microscopy to ensure that no agglutination phenomenon was set to control,observed differences in coagulation indexes of the two groups.Results The PT,APTT,TT and Fg were statistically significant(P ＜ 0.05) between experimental group and control group by the q test.Different agglutination specimens group in the experimental group by analysis of variance,PT,APTT.TT and Fg were statistically significant(P ＜ 0.05) between groups comparison of the q test analysis,PT,APTT,TT and Fg were significant differences (P ＜ 0.05).With the aggravation of blood specimens agglutination,PT,APTT and TT time extension and Fg concentration reduce more serious.Conclusion Optical microscope before the introduction of clotting function tests experimental quality control a large extent,to enhance the accuracy of laboratory coagulation test results,clinical diagnosis and preoperative preparation has important clinical value.
