Asthma is heterogeneous disorder which caused by a complicated interaction between multiple genes and environmental factors. A increasing number of attention has paid in the researches about its pathogenic mechanism and therapeutic strategies. Not only can Toll-like receptors and signal transduction pathways mediate relevant immunocyte of asthma, but also induce or restrain development of asthma. TLRs is a land of pattern recognition receptor(PRRs), which can rely on the conserved sequence of gene encoding to identify pathogenic microorganism, meanwhile activate innate immunity,adjust acquired immunity and induce immune tolerance.

It is one heated topic to enhance the humanistic quality of current college students.This paper investigates and analyzes the status quo of humanistic education among the college students in two medical colleges in Tianjin city,exploring related issues in the humanistic education in the English language lecture teaching in medical colleges.

Objective To explore the effect of polyethylene terephthalate artificial ligament revascularization on the treatment of distal tibiofibular syndesmosis injury .Methods The data of 18 patients with distal tibiofibular syndesmosis injury in our hospital from March 2013 to March 2014 were retrospectively analyzed .Fourteen patients received the bilateral suspension fixed technology ,and 4 cases were fixed with unilateral suspension fixation by extrusion screw which could be absorbed .The ankle joint mobility was measured during the follow-up,which were evaluated by American orthopedic foot and ankle society ( AOFAS) .Results Eighteen patients with distal tibiofibular syndesmosis in-jury were followed up for 12~17 months,with an average of 13.5 months.Imagings showed that the tibiofibular space was normal on postop-erative X-ray films,and there was no lost in 1 year.The PET of artificial ligaments were taken out ,and the artificial ligament and bone tissue were combined with a good ligament toughness .The pathological examination revealed the fibrous tissue grew in the artificial ligaments .Ac-cording to AOFAS ankle function grading evaluation of curative effect ,11 cases were excellent ,6 cases were good ,and 1 case was not obvious . Conclusion PET artificial ligament revascularization can recover the hinge functions of tibiofibular syndesmosis for patients with early recov -ery of ankle plantar flexion range in a short time .Different ways of fixed ligament had no obvious effect on functional recovery ,however,the extrusion screw technology can shorten the time of surgery .

To investigate the efficacy and the clinical value of total laparoscopic radical hysterectomy (TLRH) for the treatment of uterine malignancies, we performed a retrospective review of 87 patients with cervical cancer and 23 patients with endometrial carcinoma who underwent TLRH at Union hospital between June 2008 and September 2009. Data collected included operative time, estimated blood loss, lymph node count, time for the recovery of normal temperature and time to resumption of normal bladder function, intraoperative and postoperative complications. The procedure was completed laparoscopically in 108 patients. Two patients were converted to laparotomy due to common iliac vein injury. The mean overall operative time was 200.6+/-38.6 min; the mean operative blood loss was 280.5+/-128.3 mL; he mean number of pelvic lymph nodes that were resected wa26. 0+/-5.8. The time for recovery of normal temperature and the normal bladder function after the operation was 5.8+/-2.9 d and 15.2+/-4.3 d. There were 2 (1.8%) common iliac vein injuries during the operation and 10 (9.1%) bladder retentions post operation. It was concluded that TLRH is feasible, minimally invasive and provides promise for the treatment of uterine malignancies.

To whether the unfinished form exist in the crime of illegal medical practice,the general theory of the criminal Law’s answer is negative.Because the crime of illegal medical practice is circumstance crime and behavior crime,its subjective motive includes indirect intent.In this article,by analyzing it,the author agrees with the common theory that preparatory crime and discontinuance of crime in the preparatory stage.do not exist in circumstance crime,behavioral offense and indirect intent ional crime,but insists thet attempted crime and discontinuauce of crime do exist.Then by comparatiae analysis on the difference beteem them and illegal medical practice,the author illustrate the identification criteria of attempting discontinuance of this crime and the actural illegal medical practice as wtll as the significance of this study.Finally,an example is given to support them.

Objective To explore the relationship between physical activity ( PA) in college students and self?efficacy,and provide guarantee for improving health education in colleges. Methods International physical ac?tivity questionnaire( IPAQ) ,scales of physical behavior,scales of stage of change in physical exercise behavior,and scales of self?efficacy were used to test 504 students from some of colleges in Zhejiang province. Results Signifi?cantly more males (38.52%) than females (27.27%) were in the high activity tertile (P<0.01); the amount of PA per week in males and females were (4608±872.07)MET and(4361±674.03)MET(P<0.01); the scores of males and females were (3.32±0.44) and(3.04±0.36),(P<0.01). The number of males (35.5%) in maintenance period and period of action is greater than that of females (28.9%). Males had higher self?efficacy and more scores of behavior than females (P<0.05) . There were significant characteristics of PA in their self?efficacy,score of be?havior and stages of change( F=18.38, F=15.08, F=34.71, P<0.01),and a significant correlation between PA and self?efficacy,stages of change and physical exercise behavior ( r=0.336, r=0.36, r=0.46, P<0.01).Conclu?sion Self?efficacy may have important effect on the level of PA. Stages of change and scores of behavior may ex?plain difference of PA between males and females.

Objective:To establish an HPLC method compatible with the mass spectrometry for the determination of the content and related substances in amlodipine besylate tablets. Methods:The sample was separated on a CAPCELL PAK C18 column (250 mm × 4. 6 mm, 5 μm) with the mobile phase consisting of methanol and 20 mmol·L-1 ammonium acetate (60∶40) at a flow rate of 1. 0 ml·min-1 . The detection wavelength was set at 237 nm. The column temperature was 35℃ and the injection volume was 20 μl. Be-sides, an HPLC-QTOF MS method was used to identify the molecular structure of the related substances of amlodipine. Results: The related substances were completely separated from amlodipine. The linear range of amlodipine besylate was 10-100 μg · ml-1 ( r =0. 999 8), and the mean recovery was 99. 2%(RSD=1. 0%,n=9). The main related substances could be detected by HPLC-QTOF MS. Conclusion:The established method is accurate, reliable and reproducible, which can be used in the quality control of amlodip-ine besylate tablets.

Objective　To study the malignant or benign characters of lung mini nodules for diagnosis and treatment.Methods　A retrospective analysis was performed on 80 post-operative cases with pathologically confirmed malignant or benign lung mini-nodules.Results　Lung mini-nodule resection cases accounted for 17.7%(80) out of a 451-cases group.Malignant cases accounted for 73.7%(59/80)，benign cases 26.3%(21/80).Most of the malignant cases were squamous cell carcinoma and adenocarcinoma,while most of the benign cases were tuberculosis and inflammatory pseudo-neoplasms.As for pTNM staging in malignant cases,there were 28 in pT1N0M0，19 in pT1N1M0,1 in pT1N1M1,10in pT1N2M0 and 1 in pT1N2M1;the average survival time was 29.4 months.The accurate rate of pre-operative X-ray and CT scan was 45% and 76.2% respectively.Conclusion　For patients with lung mini-nodules ＜2 cm CT value at 37HU,and the nature unknown ,resection is suggested.
