AIM:To establish a method for determining guanosine, uridine,and andadenosine for Radix Isatidis. METHODS: The Prevail C_(18) analytical column(4.6 mm?250 mm,5 ?m)was used.The mobile phases consisted of water and acetonitrile with gradient.The flow rate was 0.5 mL/min and column temperature was at 25 ℃.The detection wavelength was at 254 nm. RESULTS: The method had good linear relationship within the range(1.92)-38.4 ?g/mL;1.75-35 ?g/mL; 2.12-42.4 ?g/mL of guanosine,uridine and andadenosine,respectively,with the correlation coefficients of 0.999 9.The average recoveries of the three nucleosides were 99.64%(RSD=0.38%),98.94%(RSD=0.32%) and 98.85%(RSD=0.48%),correspondingly.CONCLUSION: The method is fast,rapid,convenient,accurate and can be used for quality control of Radix isatidis.

At the beginning of a standard item, the standardized objects and involved contents should be demonstrated thoroughly, which is the precondition of establishing a good standard. After the proposal of this standard, a high-level drafting group should be built, led by top specialists who also draft the standard, which is essential to guarantee the quality of the standard. Before drafting the standard, literature regarding this standard should be searched completely, and Directives for Standardization should be learned to understand the basic requirements of establishing a standard; in the meanwhile, selections on standardized contents and quantitative boundaries of technical indices should be comprehensively and deeply studied. At the stage of consultation, focus should be paid on the scope of the consultation departments, level and personnel quality. As for standard review, it should be precise and truth-seeking. At the stage of submitting and authorization, it is necessary to have timely communication. Only by full cooperations of all parties, and by strictly following the procedure, method and rule of standard establishment, can a high-quality acupuncture-moxibustion standard be established.

Technology and technique of coronary artery stent have been developed to a certain degree, restenosis rate of metal stent reduces to 15%, but coronary artery stent is still difficult for long-term effect of interventional therapy on coronary atherosclerotic heart disease. Drug-eluting stent is newly discovered during recent years, while it is prospect for preventing restenosis postoperatively. Although clinical efficacy of drug-eluting stent is encouraged, indication is still simple. In addition, some events related to drug-eluting stent remain poorly unknown. This study was designed to compare security between drug-eluting stent and metal bared stent, analyze major factors correlated with security of drug-eluting stent, and investigate the development of drug-eluting stent.

The oxygen inhaler,widely used in clinic,is ranked in country's forcible inspection medical instrument for its high-risk. With good preparation of inspection environment and auxiliary instrument,XY-90A buoy type oxygen inhaler was inspected in regular measure,and the inspection of exhaust pressure of safety valve was realized. The inspection quality of oxygen inhaler is guaranteed.

BACKGROUND: Nerve fiber degeneration and horseradish peroxidase antrograde tracing methods are commonly used to study nerve pathway. However, both the methods cannot mark the area clearly and lack of sensitivity so that they cannot fully present the projection area of nerve fibers. It needs further efforts on developing new nerve pathway tracing methods to effectively research nerve pathway.OBJECTIVE: To look for a highly sensitive method of nerve pathway tracing in order to provide a simple, objective and reliable method to study regeneration.DESIGN: A randomized and controlled trial based on experimental animals.SETTING: Department of Internal Medicine of a hospital and the Experiment technique teaching section of a university.MATERIALS: The experiment was completed in the Experiment Technique Teaching Section of Chengdu Medical College. Six healthy male SD rats provided by Experimental Animal Centre of West China Medical University were used.METHODS: Using CB-HRP as tracer while using sodium tungstate as stabilizer of TMP to antrograde tracing the projection of optic nerve fibers on anterior region of hypothalamus and retrograde tracing the distribution of hypoglossal nerve fibers on the dorsal side of medulla.MAIN OUTCOME MEASURES: Distribution and dyeing of neuron bodies and nerve fibers.RESULTS: The fibers of optic nerve projected to the dorsomedial side of suprachiasmatic nucleus and the fibers of hypoglossal nerve projected on the hypoglossal nucleus on dorsomedial portion of the medulla oblongate. The result shows that the neurons and axons are very clear.CONCLUSION: It is a highly sensitive method to trace nerve pathway by using CB-HRP as tracer and sodium tungstate as stabilizer of TMB.

Objective:To discuss the appropriate thyroid operation for the treatment of bilateral multinodular goiter.Methods: 328 bilateral multinodular goiter patients undergoing surgery in the department of general surgery of Capital Medical University Beijing Tongren Hospital from June 2012 to June 2016. were retrospectively analyzed. Of these patients, 85 underwent hemithyroidectomy combined with contralateral nodule resection or subtotal resection and 243 underwent bilateral subtotal thyroidectomy. The rate of postoperative complications and recurrence between hemithyroidectomy combined with contralateral nodule resection or subtotal resection and bilateral subtotal thyroidectomy were compared.Results: The follow-up time was 1 month to 48 months after operations. In hemithyroidectomy combined with contralateral nodule resection or subtotal resection group 1 patient developed recurrent laryngeal nerve palsy, 2 patients had transient hypoparathyroidism and 1 patient had hematoma in the operative cavity. In bilateral subtotal thyroidectomy group, 2 patients developed recurrent laryngeal nerve palsy and 2 patients had subcutaneous hematoma. The rate of recurrent disease was 2.35%(2 patients) in hemithyroidectomy combined with contralateral nodule resection or subtotal resection group and 7%(17 patients) in bilateral subtotal thyroidectomy group. There was no patient in both groups needed reoperation.Conclusions:Hemithyroidectomy combined with contralateral nodule resection or subtotal resection had similar complication rate compared with bilateral subtotal thyroidectomy, but it had a significantly lower risk of recurrence than bilateral subtotal thyroidectomy, Furthermore, the rest one lobe could be resected for many times which would not cause severe complications. Hemithyroidectomy combined with contralateral nodule resection or subtotal resection is worthed to be recommended.
