OBJECTIVE: To establish the quality standard of Guanxinjing capsule. METHODS:Ligusticum chuanxiong, Borneolum Syntheticum, Radix Paeoniae Rubra, Panax ginseng and Panax notogiseng were identified qualititively by TLC. The content of Protocatechuic aldehyde in salvia miltiorrhiza was determined by HPLC. RESULTS: The TLC spots were distinct and well-separated. The average recovery of the added sample was 99.91% and RSD was 1.56%. CONCLUSION: The established standard is suitable for the quality control of Guanxinjing capsule.

OBJECTIVE:To optimize the coating technology of modified release film of budesonide colonic localization tablet. METHODS: The effect of the coating parameters such as spray gun position, spraying rate, spraying atomization pressure, intake air temperature and flow, temperature of tablet bed on the microporous semipermeable film and the enteric film of localization tablet were investigated, respectively. RESULTS: The distance between spray gun muzzle and tablet bed was established as 10～20 cm; the spraying rates of the microporous semipermeable film and the enteric film of localization tablet were 3 and 1 mL?min-1, respectively, with their spraying atomization pressure at 2 and 1.5 bar(1 bar=105 Pa), intake air temperature at 50～55 ℃ and 40～45 ℃, temperature of tablet bed at (40?1) ℃ and (30?1) ℃, flow rate of intake air at 5 and 7 m3?min-1 respectively. The weight of the optimized localization tablet after being coated with semipermeable film and enteric film increased by 10% and 5%, respectively. The cumulative drug release within 24 h reached (77.5?8.6)% and the lag time was (6.0?0.5) h. CONCLUSIONS: The optimized coating technology is suitable for the preparation of modified film of budesonide colonic localization tablet.

PBL and CTM integration method is a kind of heuristic education mode of regarding student as the center of education.In order to explore the application result of this teaching method in the curriculum of nursing ethics laws and regulations,we put this mode into practice and regard nursing students as research objects.Questionnaire investigation and paper test are applied to evaluate the teaching effect.The study result shows that PBL and CTM integration method is certainly a well-established method to enhance teaching quality in the curriculum of nursing ethics laws and regulations.

Acute cerebral infarction needs a fast and effective imaging examination to help determine the diagnosis,analyze the causes,guide the treatment,and determine the prognosis.Multimodal CT examination obtains a wide range of reformation in a single scan,including anatomy,hemodynamics and etiology,and provides objective imaging evidence for comprehensive evaluation and appropriate treatment of cerebral infarction.This article reviews the application of this technology in acute cerebral infarction.

Congenital heart disease and airway anomalies are correlated,and some special cardiovascular anomalies accompanying with airway anomalies like vascular tings,have a high morbidity.Congenital heart disease with airway anomalies is usually ignored in clinic.It should be considered that congenital heart disease with airway anomalies exists in children with the symptoms,such as repeated stridor,respiratory failure,difficult intubation or failure of postoperative ventilator weaning.Multidetector helical CT and bronchoscopy are important for making early diagnosis and guiding management for congenital heart disease with airway anomalies.The choice of therapeutic approaches depends on the type of airway anomalies,location and degree of the lesion.

Objective To analyze clinical features of papillary thyroid microcarcinoma(PTMC) and to evaluate the diagnosis and treatment for PTMC.Methods The clinical data of 447 cases of PTMC receiving surgical treatment and confirmed by pathology were reviewed.Color Doppler ultrasonography was used to identify thyroid nodules and cervical lymph nodes,and frozen section was used to confirm the pathological diagnosis during operation.104 cases received unilateral lobectomy,22 cases received unilateral lobectomy plus isthmectomy,321 cases received total thyroidectomy,257 cases underwent central neck dissection,and 54 cases underwent lateral neck dissection(level Ⅵ included).All cases took levothyroxine to maintain low TSH level after operation,and were followed up through telephone or in out-patient clinic.Results Central compartment node metastasis was found in 144 patients,and lateral neck metastasis was found in 41 cN1 cases.The age,extra-capsular invasion and multifocal carcinoma were independent risk factors of PTMC.The number of positive nodes in level Ⅵ was positively correlated with the risk of lateral node metastasis.395 cases were followed-up successfully for 20 to 42 months,with the media follow-up of 32 months.During the follow-up,recurrence or metastasis was found in 15 cases,and no death happened.Conclusions PTMC has no specific symptoms,and was difficult to be diagnosed before operation.Physical examination and color Doppler ultrasonography should be used as routine examination.Thyroid lobectomy and total thyroidectomy plus central node dissection should be major surgical treatment for PTMC patients.Lateral neck dissection should be considered in all cN1 patients.

Objective To analyse the effects of OPG (osteoprotegerin, OPG) at different concentrations on activity of osteoclasts (osteoclasts, OC) , and the relationship between them in physiological activity and function.Methods The bone marrow cells of six weeks old female mice were collected and cultured in vitro on the basis of adding different levels of OPG(10, 20, 50, 100 μg/L).The relationship between OPG and OC were analysed by tartrate resistant acid phosphatase ( TRAP) staining, F-actin cytoskeleton staining and bone resorption pits.Results OC showed adherent growth within 1h cultured, and there were no large multicore OC.Cultured for 5 days, the smaller monocytes gradually began to fusion with each other to form multinucleated cells and showed distinctive characteristics.After three days OPG treatment, the number of multicore cells gradually reduced with OPG concentration increaseing in experimental group, and showing a negative correlation between them(r=-0.516,P<0.05).And there were only a small amount of multinucleated cells at OPG concentration of 50 μg/L.At 20,50 μg/L of OPG concentration, OC number significantly decreased compared with control group (P<0.05), and when the concentration of OPG was 100μg/L, OC number showed significant reduction (P<0 01).the experimental group OPG bone resorption lacunae area, density and decrease the degree were positively correlated with concentration of OPG (r=0.459;r=0.426;r=0.389,P<0.05), and the area had a significant difference when two groups compared.Conclusion The inhibitive effects of OPG on OC function and activation increase with concentration increasing.

Being the kernel of functional gene group,the field of protein group becomes the focal point of life science research in 21th century.SELDI,which is based on the combination of chip technology and mass spectrum technology,has become the main method for filtrating tumor marker in clinical research.This paper introduces the basic principle of SELDI system and summarizes the application of SELDI to tumor marker detection in galactophore cancer.
