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 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 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 develop a RP-HPLC method to determine adenosine in Chongcaoqizhi granule. Method The separation was performed in a Kromasil ODS-1 column (250 mm?4.6 mm, 5 ?m) with a mobile phase of phosphate buffer solution (pH 6.5) - methanol (85∶15). The flow was 0.7 mL/min and the detective wavelength was set at 260 nm. Results The standard adenosine showed a good linear correlation at range of 1.016~12.192 ?g/mL. The linear regression equation and correlation coefficient (r) were Y =169339X -82318, r =0.9990, respectively. The average recovery of the loading was 98.02% and the RSD was 1.72%. The average content of adenosine was 12.45 ?g/g. Conclusion This method is accurate, reproducible and highly selective, and can be used for quality control of Chongcaoqizhi granule.

OBJECTIVE:To investigate clinical efficacy and safety of Xuebijing injection in the treatment of chronic ob-structive pulmonary disease (COPD) complicated with community-acquired pneumonia (CAP). METHODS:A total of 88 COPD patients with CAP selected from our hospital during Feb. 2013-Jan. 2015 were divided into control group and observa-tion group according to random number table,with 44 cases in each group. Control group received routine treatment as an-ti-infection,reducing phlegm,fluid replacement,nutritional support,etc. Based on control group,observation group was ad-ditionally given Xuebijing injection 50 mL added into 0.9% Sodium chloride injection 100 mL,ivgtt,for 30-40 min,bid, for consecutive 10 d. Clinical efficacy,application time of antibiotics,pulmonary function indexes [FEV1,FVC,FEV1/FVC,VC] were observed in 2 groups. The occurrence of ADR was recorded. RESULTS:Total response rate of observation group was 88.64%,which was significantly higher than 70.45% of control group,with statistical significance(P<0.05). The application time of antibiotics in observation group was significantly shorter than control group,with statistical significance (P<0.05). There was no statistical significance in FEV1,FVC,FEV1/FVC,VC between 2 groups before treatment (P>0.05). After treatment,FEV1 and VC of 2 groups were improved significantly,and the observation group was better than the control group,with statistical significance(P<0.05). There was no statistical significance in FVC,FEV1/EVC before and af-ter treatment and betwean the two groups (P>0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Xuebijing injection has significant therapeutic efficacy for COPD complicated with CAP and can significantly shorten the use time of an-tibiotics,improve pulmonary function with good safety.
