Objective To compare the effect of different dose human immunoglobulin for intravenous injec-tion( IVIG) in the treatment of Kawasaki disease ( KD) .Methods According to different time ,55 children with KD were divided into two groups.26 patients between January 2002 and February 2006 were selected as group A,while 29 patients between October 2006 and June 2013 were selected as group B .Patients in group A were given IVIG 0.4 g· kg-1 · d-1 ×5d,while group B was given IVIG 2 g· kg-1 · d-1 ×1d.Then,the time of fever-reducing and CAL of the two groups were compared .Results The time of fever-reducing in group A was (38 ±4) h,that in group B was (34 ±3)h,there was significant difference between the two groups (t=4.15,P<0.05).The incidence rate of CAL in group A was 6.9%,which was higher than 6.1%in B group,but the difference was not statistically signifi-cant(χ2 =0.253,P>0.05).Conclusion The treatment of KD with IVIG 2 g· kg-1 · d-1 ×1d is more superior than IVIG 0.4 g· kg-1 · d-1 ×5d.

Microglia(MG)is recognized as the main immune effector in central nervous system injury and disease.MG can regulate the tumorigenesis and development of brain metastases tumor(BMT)by different ways.Studing the roles and mechanisms of MG in BMT will provide new insights into the prevention and treatment of BMT.

Objective To evaluate the teaching quality of AIDS and drug abuse and to provide evidences for teaching improvement.Methods Quantitative research and qualitative research was combined.Questionnaire including evaluation of curriculum,teachers and teaching quality was conducted among 273 students majored in anesthesiology and clinical medicine (2006 grade) as well as in forensic medicine,laboratory and stomatology (2008 grade) in quantitative research.Observation and indepth interview were used in qualitative research to observe the teaching process and receive students'feedback.Information about students' evaluation criterions and attitude toward teachers were collected by qualitative research.Chi-square test and descriptive statistic were used with SPSS 13.0.Results 90.8％ students thought this lesson was necessary and important and the contents were accepted by them.24.2％ students expected increasing study hours and having practice classes.Evaluation of course time,contents and importance were different by students of different majors.Average scores of students' evaluation on teachers' quality,teaching contents and teaching methods were 25.2,22.4,11.0,respectively.Three aspects of teaching methods got the lowest scores:vivid (2.71 points out of 3.0 points),interaction (2.71 points out of 3.0 points) and flexibility (2.72 out of 3.0 points).Interview results demonstrated that students have diversified demand for teaching methods and expect to increase practice lessons and multimedia teaching as well as to effective communicate between teaching and learning.Conclusions Course of AIDS and drug abuse is accepted by students.As a whole,students are basically satisfied with teachers,however,teachers and related sectors should pay more attention to teaching method improvement and teaching skill enhancement.

Selective salpingogram(SSG)and hysterosalpingography(HSG)have achieved fairly reliable diagnostic value. SSG and transcervical fallopian tube recanalization(T-FTR)possess rather credible therapeutic value,long-term effect and low risk. Recanalization rate and pregnancy rate,combining with the measurement of tubal perfusion pressures(TPP)and development of ultrasonic technology,can evaluate the therapeutic effect and safety more generally and objectively. Researches in the future should lay emphasis on developing non-radiologic technique,promoting diagnostic veracity,reducing side effects,and establishing randomly control trials together with consolidating the standardized evaluation criteria.(J Intervent Radiol,2007,16: 714-717)

Disuse-related osteopenia is mainly due to decrease of bone formation which relates closely to the changes of osteoblast function and differentiation. Bone marrow mesenchymal stem cells which are multipotent cells present in bone marrow can differentiate into osteoblast. The factors which regulate the osteogenic differentiation of bone marrow mesenchymal stem cells were introduced. This will increase the understanding and aid in the prevention and treatments of bone loss to create a healthier life for astronauts and patients after disuse.

Objective To analyze the expression of apoptosis-relared genes of retinal blood vessel in early diabetic rats by gene chip technology. Methods To make diabetic rat model by intraperitoneal injection of streptozotocin (STZ). On the 6th week after blood pressure increased, 10 rats were executed in Diabetic group and normal control group respectively. 20 retinal blood vessels were extracted and the RNA was isolated. The probe was made of α-32 P-deoxyadenosine triphosphate (dATP)-labeled sample which hybridized 1176 nylon chips, and then analyzed by software. Three different expression genes were selected to verify by reverse transcription polymerase chain reaction (RT-PCR). Results On the 6th week, 136 (11.5%)genes were differentially expressed [up-regulated genes were 90 (7.6%), down- regulated genes were 46(3.9%)] in diabetic group. These genes involved into different groups according to their function. Especially in 72 apoprosis-related genes, 15 genes were differentially expressed. The up- regulated genes were some TNF receptor family members such as TNFRSF12, TRAIL, TNFRSF9, FADD;Bcl-2 family members such as bcl-w, bax, bakl and AKT. The down-regulated genes were FAF1 which related to fas. Conclusions The expression of retinal vascular gene in early diabetic rats has been changed complicatedly. In particular, the multiple apoptosis-related genes have been changed in early diabetic, and most of them are at the upstream of apoptosis pathway. These findings indicate that the development of diabetic retinopathy is associated with multiple signaling pathways leading to apoptosis, while the alterations on the level of molecular biochemistry are still limited in apoptosis induction period.

Objective]To investigate academic thoughts of Prof. Yan Dexin in spleen and stomach syndrome treatment.[Methods]The paper summarized the academic origin, academic thoughts as well as practical treatment cases of Prof. Yan Dexin ’s spleen and stomach syndrome treatment theory. [Results]The main points of Prof. Yan’s academic thought on spleen and stomach therapy has succeeded and developed the therapy of Menghe physician, which includes an emphasis on spleen Qi rise and stomach Yin drop, Qi of spleen and stomach regulation, special attention on the function of the stomach-yang and spleen-yin, an advocation ofspleen leading four organs, and therapy design from spleen with an ingenious use of atractylodes rhizome, Atractylodes and Zhizhu pill. [Conclusion] Professor Yan Dexin developed his unique theoretical system in spleen-stomach diseases therapy on basis of the experiences of spleen and stomach disease treatment from ancient physicians, which is instructive for later physicians.

Cytokines play an important role in the genesis and development of tumor.Antitumor mechanisms of some cytokines are clearly testified.Currently,the main cytokines used in tumor clinical treatments are interferons,interleukins and tumor necrosis factors.For the lack of specificity,there are too many side effects for some patients to continue.So the application range of cytokines in tumor clinical treatment is limited.The most important measures to develop cytokines therapy are improving the stability of curative effect and reducing side effects.

Objective To analyze the clinical features and causes of benign paroxysmal positional vertigo(BPPV).Methods The clinical data of 521 patients with BPPV were collected.The percentage of patients with BPPV in all the outpatients with dizziness and vertigo,the clinical characteristics of BPPV,and the prevalence of comorbidity with migraine were analyzed.Results BPPV accounted for 35.7% of patients with vertigo and 12.1% of patients with dizziness.Among the 521 patients with BPPV,158(30.3%)were male and 363(69.7%)were female,with an average age of(57.5?12.8)years old(20 to 93 years old).Right semicircular canals were involved in 323 cases(62.0%),and left semicircular canals in 187 cases(35.9%).The latency period of nystagmus of vertical canals was(3.22?2.37)s,and time of persistence was(8.31?7.98)s.The latency period of nystagmus of horizontal canals was(2.33?1.50)s,and the time of persistence was(14.77?11.40)s.There were significant differences in the latency period of nystagmus and time of persistence between the vertical and horizontal canals(P=0.001 and P=0.000).Fifteen patients(2.9%)had a history of head trauma and 39(7.5%)were complicated with migraine.Conclusion BPPV is prevalent in patients with dizziness and vertigo,and misdiagnosis and missed diagnosis should be avoided.
