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.

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.

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.

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.

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 determine the value of spiral CT in diagnosis of endobronchial tuberculosis(EBTB) after analysing the spiral CT appearance. Methods　Retrospective analysis of CT signs in 13 cases who were finally pathologically found suffering from EBTB via biopsy with bronchoscope. Results　Five cases have signs of bronchial structure with obstructive atelectasis and pneumonia. Two cases have signs of irregular bronchial wall. Four cases have signs of scattering dot and patchy increase density in lung fields. Two cases' bronchi and lung tissues are normal. Conclusion　CT examination can determine the site and extent of EBTB and help the localization of bronchoscope.

Objective:To investigate the association between anxiety and the change of humoral immune functions and its correlation with HLA-DQB1 polymorphisms.Methods:Total 31 resident doctors were selected randomly and tested by State-Trait Anxiety Inventory(STAI).IgG,IgA,IgM,complement C3 and complement C4 were detected with BECKMAN array360 system;HLA-DQB1*02、*03、*04、*05 and*06 alleles were individually amplified by polymerase chain reaction(PCR)using exon2 group-specific primers.The correlation between immune function and HLA-DQB1 polgmorphisms were investigated.Results:Statistical analysis showed that there was positive correlation with State Anxiety (Ta) and complement C3,either Trait Anxiety (Tc) and complement C3.There was significant difference between HLA-DQB1*02 positive and negative in Ta (P＜0.05),while no difference in complement C3(P＞0.05).There was significant difference between HLA-DQB1*04 positive and negative in Ta and Tc(P＜0.05),while no difference in complement C3(P＞0.05).Conclusion:Anxiety could change some humoral immune functions and this is related with HLA-DQB1 polymorphism.

Objective To evaluate the effect of the Danhong injection combined with irbesartan in treatment ofearly diabetic nephropathy. Methods 64 patients with early diabetic nephropathy were randomly divided into two groups and the control group 32 cases,two groups were given control of blood sugar and ensure water and electrolyte balance,support therapy,in which 32 cases were also observed red Danhong injection,Ecuador irbesartan treatment,2weeks before evaluation. Results The total effective rate in treatment group was higher than the control group( x2 =6.38 ,P ＜0. 05) ,after 12 weeks of treatment,two groups of urinary protein decreased significantly compared with before treatment, including observation of urine protein was ( 0. 6± 0. 1 ) g/24h, the control group was ( 0. 7 ± 0. 3 ) g/24h,and decreased urine protein level of the observation group was better than the control group( t = 2. 74,P ＜ 0. 05 ). And in the course of treatment, side effects and serious adverse events were not found. Conclusion Danhong injection combined irbesartar, could improve the clinical symptoms, reduce microalbuminuria in treatment of early diabetic nephropathy is worthy of wider application.
