In order to provide an experimental evidence for clinical utility, we undertook a series of experimental studies of glucocorticosteroid to treat closed head injury and gun shot brain wound, For studies of closed injury in rats, there were four groups as follows: Group 1: methyl prednisone 30mg/kg (MPG); Group 2: dexamethasone 5 mg/kg (HDMG): Group 3: dexamethasone0.5mg/kg (LDMG); and Group 4: normal saline as a control group (CG) For study of gun shot wound of brain, The dogs were divided into three groups, Grup 1 (wound group, n=8); Group 2 (treated group, n=7) and group 3 (control group, n=7). After injury, the vital signs were observed, the water content of the brain and Even' s blue level were measured and the brain were examined under optical and electronic microscopy, All results proved that secondary traumatic edema in the animals used high dose glucocotricosteroid were much more slight

The left ventricular bands of isolated human heart were studied by microscopy, echocardi ography and gross anatomical method. The results indicate that the structures of the bands were those commonly observed in human heart. They could be classified into two types: myo-bands and tendinous bands. However, we could only differentiate the “bands whose” diameter was more than 1.5mm with Aloka-SSD720 echocardiograph (made in Japan). we suggest that the resolution of the instrument we used was too low, and this might be the main reason that the detection of left ventricular bands was much lower than the incidence, we classified these bands according to the adhering points and diameters of bands.In this paper, the forming factors of bands and their clinical significance are also discussed.

The effect of high dos; dexamethasone(5mg/kg wt, intravenous injection)to prevent and treat the secondary pathological damage of craniocerebral injury was studied in animal models of craniocerebral injury caused by high-velocity missiles in dogs.We observed ths physiological changes, analyzed the value of serum and. cerebrospinal fluid lactate dehydrogenase, estimated the permeability of blood brain barrier (BBB) and studied brain pathology by light and electron microscopy.The results suggest high dose dexamethasone can help to restore ths structure and function of BBB, protect brain cells as well as lessai the secondary pathological damage in tha respiratory and circulatory systems and reduce th production of lipoptrox-ides(LPO).

Objective To evaluate the association between genetic polymorphisms in promoter regions of matrix metalloprotein‐ase‐1 (MMP‐1)‐1607bp1G/2G ,matrix metalloproteinase‐7 (MM P‐7)‐181‐bpA /G and susceptibility of cervical cancer using Meta‐analysis .Methods Relevant studies that had relationships of the polymorphism in promoter regions of matrix metalloproteinase‐1 (MM P‐1)‐1607bp1G/2G ,matrix metalloproteinase‐7 (MMP‐7)‐181‐bpA /G and susceptibility of cervical cancer were collected as case‐control groups .RevMan5 .0 software was applied to analyze the odds ratios (OR) and 95% confidence intervals(CI) of the as‐sociation between polymorphisms and susceptibility of cervical cancer .Results Finally ,6 studies were selected ,containing 4 studies of MMP‐1 and 2 studies of MMP‐7 .For MMP‐1‐1607bp1G/2G ,OR was 0 .76 (95% CI = 0 .51 - 1 .13 ,P= 0 .17) under 1G/1G +1G/2G ∶ 2G/2G model ,OR was 0 .72 (95% CI = 0 .42 - 1 .23 ,P = 0 .42) under 1G/1G ∶ 2G/2G model ,OR was 0 .79(95% CI =0 .57 - 1 .09 ,P= 0 .15) under 1G ∶ 2G model ,it was concluded that there was no statistical significance between them .For MM P‐7‐181bpA /G ,OR was 0 .47 (95% CI = 0 .30 - 0 .74 ,P= 0 .001) under AA + AG ∶ GG model ,OR was 0 .43 (95% CI = 0 .26 - 0 .74 , P= 0 .002) under AA ∶ GG model ,OR was 0 .77(95% CI = 0 .62 - 0 .94 ,P= 0 .02) under A ∶ G model ,there were statistical signifi‐cance differences under all models .Conclusion Polymorphisms in promoter of MMP‐7‐118bpA/G are associated with the suscepti‐bility of cervical cancer and an allele is a protective factor .It is still not confirmed that significant association between the MM P‐1‐1607bp1G/2G and susceptibility to cervical cancer exists in current literature .

Interventional radiology is a new kind of minimally-invasive therapeutics that has developed on the basis of radiological imaging diagnosis.Interventional radiology is defined as a clinical subject that carries out the specific diagnosis and treatment under the guidance of medical imaging equipment and with the help of puncture needle,guide wire,catheter,etc.The interventional radiology categories include interventional diagnosis and interventional therapy.Interventional medicine is defined from the perspective of clinical application,while interventional radiology is defined from the technical characteristics of diagnosis and treatment.《of Interventional Radiology》 and the upcoming 《Journal of Interventional Medicine (English version)》 will become the professional sister journals in interventional academic field,which will provide important support for promoting the development of interventional medicine in China and for enhancing the international influence power of Chinese interventional medicine.

Objective: To observe the clinical effects on advanced esophageal cancer by combined Xihuang Pill with chemotherapy. Methods: Dividing 35 advanced esophageal cancer cases randomly into two groups: 18 cases in the treatment group and 17 cases in the control group. Cases in the control group were treated by nedaplatin 40mg/m2,d1,2; 5-Fu400mg/m2,d1-5; CF200 mg/m2,d1-5. While the treatment with Xihuang Pill combined. The difference of quality of life, hematological toxicity, efficacy and symptoms between the two groups was observed. Results: The quality of life, remission rate of some symptom in the treatment group were much better than the control group, and the hematological toxicity and efficacy were the same. Conclusion: Xihuang Pill could improve the quality of life of advanced esophageal cancer patient, and alleviate some symptoms.

Objective To compare the effects of transabdominal hysterectomy(TAH),transvaginal hysterectomy(TVH),and laparoscopic assisted vaginal hysterectomy(LAVH).Methods Clinical data of 48 cases of TAH(TAH Group),38 cases of TVH(TVH Group),and 31 cases of LAVH(LAVH Group) were retrospectively analyzed.Results The operation time was shorter in the TAH Group(73.7?5.9 min) than in the TVH Group(80.9?7.0 min) and the LAVH Group(129.3?9.1 min)(F=612.04,P=0.000).The intraoperative blood loss was greater in the LAVH Group(142.8?17.1 ml) than in the TAH Group(128.1?9.6 ml) and the TVH Group(129.7?10.2 ml)(F=15.18,P=0.000).The postoperative analgesic requirement rate was higher in the TAH Group(75.4%,36 cases) than in the TVH Group(30.2%,11 cases) and the LAVH Group(38.4%,12 cases)(?~2=20.310,P=0.000).The length of postoperative hospitalization was longer in the TAH Group(7.3?1.6 d) than in the TVH Group(4.8?1.0 d) and the LAVH Group(5.1?1.1 d)(F=47.07,P=0.000).The postoperative pyrexia rates were not significantly different among the TAH Group(8.4%,4 cases),the TVH Group(7.4%,3 cases),and the LAVH Group(8.2%,3 cases)((?~2=0.074,) P=0.964).Conclusions As compared with transabdominal hysterectomy,transvaginal hysterectomy and laparoscopic assisted vaginal hysterectomy show advantages of less invasion,less pain,and quicker recovery.

As a new way,on-line bid & purchase expands and deepens the bid principle of "Honest,Justice,Public". This paper analyzes the characteristics of on-line bid,puts forward the centralized bidding frame based on Internet,and optimizes the bid procedure. The study not only makes the on-line bid more effective and strict but also makes the bid result more convincing.

The planned digital textbook Human Parasitology, the first of its kind, published by People's Medical Publishing House is an important medical education effort that features the inte-gration of digital resources. This paper introduces the digital textbook construction goal, namely using paper-based textbook for five-year undergraduates as blueprint to reasonably display the digital re-sources based on the features of the discipline. The advantages of this digital approach over traditional paper-based textbook in demonstrating parasitic morphology, lifecycle, pathogenesis, diagnosis, epi-demiology and control are discussed. Valuable experiences in planning and constructing this digital textbook are to be shared.
