The humanity education of science and engineering college has brought not only historical chance but also impact and challenge with the coming of new century.This text has probed into graduate students' humanity education requirement and countermeasures.

Objective To improve the recognition of sarcoidosis in elderly patients.Methods Clinical data of 13 elderly patients with sarcoidosis were retrospectively analyzed.Results There were three cases without symptom and five cases with intra-pulmonary and extra-pulmonary manifestations respectively.Eight cases had atypical radiological appearances and five cases showed inflammatory changes through bronchofibercopy.There were three cases with increased percentage of lymphocytes and high ratio of CD4/CD8 in bronchoalveolar lavage fluid (BALF) respectively.Seven cases were diagnosed through biopsy.And the symptoms of all thirteen patients diminished after treatmeit.Conclusions The clinical symptom and radiologieal manifestation of sarcoidosis in elderly patients are varied and usually atypical.The diagnosis should be based on comprehensive analysis including clinical manifestation and examination.The elderly patients with indication of treatment can be given corticosteroid therapy with close clinical monitoring.

TFL1 homologs play important roles in maintaining vegetative growth and inflorescence meristem identity. The plants without the function of this gene usually are flowering earlier. Their normal inflorescence development is inhibited, the inflorescence meristem eventually acquired floral identity, which producing a terminal flower. Up to now, the TFL1 homologs have been isolated from 28 species of plants, including Arabidopsis, Snapdrogen and Tomato. The phylogenic tree of TFL1 proteins is almost accordance with the relative of those plants. The inflorescence identity gene TFL1 interacted with floral meristem identity genes LFY and AP1, so as to retard the transformation from inflorescence identity into floral identity. These meristem identity genes such as TFL1 and LFY can be applied in breeding of earl-flowering cultivars, there also have plenty of potentials in breeding fruit-free plantanus, popular or willows.

Slow coronary flow phenomenon(SCFP) is an angiographic observation characterized by delayed distal vessel opacification in the absence of significant epicardial coronary disease. Only limited studies have been focused on the etiologies, clinical manifestations and treatment of this unique angiographic phenomenon. In our case report, we described an 85-year-old man who came with significant ST segment elevation in leads V1-V4 and V3R-V5R without increase in myocardial enzyme. The patient also developed respiratory failure requiring intubation and mechanical ventilation. Coronary angiography revealed only mild atherosclerosis without spasm or thromboembolic occlusion. Slow flow was seen in all coronary arteries, especially in the left anterior descending and right coronary arteries. This case speculated that transmural myocardial ischemia with ST segment elevation might be resulted from slow coronary flow. Transmural myocardial ischemia can occur owing to abnormalities of the coronary microcirculation.

ObjectiveTo comprehensively evaluate the curative effect ofTCM reating type 2 diabetes with three type dialectical therapy by Fuzzy Mathematics.Methods261 cases of 2 type diabetes were divided into three groups by syndrome differentiation,as follows:type of heat with yin deficiency,type of deficiency of both qi and yin,and type of deficiency of both yin and yang,and received corresponding therapies.The course of treatment was 24 weeks,in the first 12 weeks (period 1),on the basis of western medicine treatment,patients of the three groups were respectively treated by qingrungranules,ziyigranule and shuangtiaogranules.In the next 12 weeks (period 2),all patients were only treated by western medicine.The value of FBG,P2BG,HbAlc,TC,TG,BMI of the two periods were comprehensively evaluated by the methods of fuzzy mathematics.ResultsAt the end of period 1,the total effective rate of the type of heat with yin deficiency was 91.38％,the type of deficiency of both qi and yin was 87.16％,and the type of deficiency of both yin and yang was 83.34％; while at the end of period 2,the total effective rate of the three types was 59.18％,48.65％a nd32.65％ respectively.ConclusionThe effective rate was obviously improved in period 1; while in period 2,the effective rate was decreased.

Objective To survey the CT radiation dose to cancer patients,and to compare it with diagnostic reference level (DRL) provided by newly issued national standard.Methods Computed tomography dose index weighted (CTDIw) of 5 CT equipments was measured by the standard phantom with typical scanning protocol and radiation dose parameters including average computed tomography dose index volume (CTDIvol),dose length product (DLP),75％ DLP with 900 adult and 300 pediatric cancer patients were collected.According to age stage,effective dose was estimated.Results The measured CTDIw for head scanning was on the same level with DRL,while lumbar vertebra and abdominal scanning were lower than DRL.To adults,DLP of cerebrovascular enhanced scanning and effective dose of abdominal enhanced scanning were the highest.To pediatric patients,there was no significant difference in DLP among different ages.Conclusion CTDI only reflects the dose contribution from a slice,but do not reflect the cumulative dose.For the patients need multiphase scanning,because they may be exposed to high dose,national standard should provide DLP value as the diagnostic reference level.Using individual scanning protocol is an effective method to reduce radiation dose of pediatric patient.

OBJECTIVE:To determine the content of ceftazidime in renal dialysate effluent in burn patients.METHODS:HPLC was used.The sample was separated on Bondapak-C18 analysis column with a mobile phase of mixture of methanol-ammonium acetate(17∶83,V/V).The flow rate was 1.0ml/min.The UV detector wavelength was set at 254nm.RESULTS:A linearity was obtained from 0.5～100?g/ml with a good correlation(r=0.9 999).The RSDs of inter-day and intra-day precision were not more than 3.The average recovery was 100.30%.CONCLUSION:The method is simple,rapid and accurate.

OBJECTIVETo verify the clinical efficacy on chronic fatigue syndrome of qi deficiency syndrome treated with acupuncture at selective time and explore the effect mechanism.

METHODSEighty patients were randomized into a selective-time-acupuncture group and an acupuncture group, 40 cases in each one. Qihai (CV 6), Guanyuan (CV 4), Hegu (LI 4), Taichong (LR 3), Sanyinjiao (SP 6) and Zusanli (ST 36) were selected in the two groups. In the selective-time-acupuncture group, acupuncture was used at 9:00am to 11:00am. In the acupuncture group, acupuncture was used at any time except in the range from 9:00am to 11:00am. No any manipulation was applied after the arrival of needling sensation. The treatment was given once every day, 10 day treatment made one session and two sessions of treatment were required. The fatigue scale was adopted to evaluate the efficacy before and after treatment in the patients of the two groups. The ratios among CD3+, CD4+ and CD8+ T cells in the peripheral blood were detected before ad b a after treatment.

RESULTSIn the acupuncture group, the total score of fatigue and the score of physical fatigue were reduced after treatment as compared with those before treatment (all P<0.05). In the selective-time -acupuncture group, the total score of fatigue, the s core of physical fatigue and the score of mental fatigue after treatment were reduced obviously as compared with those hefore treatment (all P<0. 01). The improvements in the scores of the selective-time-acupuncture group were superior to the acupuncture group (all P<0. 05). The ratio of CD3+ and CD8+ T cells was increased obviously after treatment in the two groups (all P<0. 05) and the ratio of CD4+ and CD8+ T cells was reduced obviously in the selective-time-acupuncture group (P<0. 05), which was better than that in the acupuncture group (all P<0.05). The total effective rate was 95.0% (38/40) in the selective-time-acupuncture group, which was better than 80.0% (32/40) in the acupuncture group (P<0.05).

CONCLUSIONThe acupuncture therapy at selective time is effective in the treatment of chronic fatigue syndrome of qi deficiency syndrome, which is especially better at relieving mental fatigue. The effect of this therapy is achieved probably by improving the immune function via the regulation of the ratios among CD3+, CD4+ and CD8+ T cells.
