Objective:To study the expressions of Vascular Cell Adhesion Molecule 1 (VCAM-1) and Intercellular Adhesion Molecule 1 (iCAM-1) in patients with endometriosis and to explore its effect on the onset of endometriosis.Methods:VCAM-1 mRNA and ICAM-1 mRNA were detected by real-time PCR method in 15 specimens of eutopic endometrium and 15 specimens of ectopic endometrium from patients with endometriosis(EMT group)and 15 specimens of endometrium from patients without endometriosis(control group).VCAM-1 and ICAM-1 protein were detected by Western-Blot method.Soluble VCAM-1 and soluble ICAM-1 in 44 serum of patients with endometriosis(EMT group) and 28 serum of patients without endometriosis(control group) were tested by ELISA.Meanwhile the correlation of expressions of VCAM-1 and ICAM-1 were analyzed in different groups.Results:①The expressions of VCAM-1 mRNA and ICAM-1 mRNA in ectopic endometrium were significantly higher than those of eutopic endometrium and the controls(P ＜0.01).There was no significant different mRNA expression between eutopic group and control group(P＞0.05).②The protein expressions of VCAM-1 and ICAM-1 in eutopic group were significantly higher than those of ectopic group and the control group(P ＜0.01).The protein expression of VCAM-1 in eutopic group were higher than those in the controls group(P＜0.01).There was no significant different protein expression of ICAM-1 between eutopic group and the controls group(P ＞0.05).③The concentration of sVCAM-1 and sICAM-1 in serum from patients with EMT were significantly higher than those in the control group(P＜0.01).The concentration of slCAM-1 in serum from patients with EMT in stage Ⅲ-Ⅳ were significantly higher than those in stage Ⅰ-Ⅱ (P ＜ 0.01).④There was no significant correlation in the expression of mRNA,protein and serum between VCAM 1 and ICAM-1 in ectopic group and eutopic group(P ＞ 0.05).Conclusions:The abnormal expressions of VCAM-1 and ICAM-1 in ectopic endometrium may play an important role in the development of endometriosis.The signaling pathways and protein expression way may be different between VCAM 1 and ICAM 1 in endometriosis.

BACKGROUND : After femoral neck fracture, incidences of ischemic necrosis and bone non-healing are closely related to biomechanical characteristics of internal fixation devices. Compression stress can improve fracture healing, tension force can delay fracture healing, and shear stress can inhibit fracture healing. How to relieve shear stress and expand compression stress is of significance for theories and clinical applications.OBJECTIVE: To compare the biomechanical characteristics of the two geometric configurations of three cannulated compression screws in the fixation for femoral neck fracture and to provide a theoretical foundation in the treatment of femoral neck fracture.DESIGN : Observational contrast study.SETTING: Department of Orthopaedics, the 251 Hospital of Chinese PLA; Department of Orthopaedics, the Third Hospital, Hebei Medical University.PARTICIPANTS: The experiment was carried out in the Hebei Orthopaedic Institute from November 2002 to March 2003. Five cadavers including 4 males and 1 female with similar bone mineral density (BMD) were provided by Department of Anatomy, Hebei Medical University. X-ray photographs proved that all the cadavers did not have rheumatism, tuberculosis, tumor, fracture or deformity.METHODS: Ten femurs were randomly divided into inverted and upright isosceles triangle with 5 in each group. Femur samples with femoral neck fracture were fixed with three cannulated screws and measured with the biomechanical machine (CSS-44020, made in Changchun Experimental Researching Institute, provided by Hebei Orthopaedics Institute). The compression strength, torsibility and the maximal vertical loading were compared between the two configurations of screws.MAIN OUTCOME MEASURES:①Displacement of femoral head at 600 N and 750 N during torsibility test; ②torque-moment at 2°and 4°during torsibility test;③load during maximal vertical loading test.CONCLUSION: The effect of three cannulated compression screws configured as an inverted isosceles triangle on the treatment of femoral neck fracture is superior to that of three cannulated compression screws as an upright isosceles triangle.

Objective: To observe antipyretic, diuresis, anti inflammatory and antisepsis effects of Qinglin Granules. (Herba Polygoni Avicularis, Herba Dianthi, Caulis Aristolochiae Manshuriensis, Semen Plantaginis, Fructus Gardeniae, etc.) Methods: The model of pyretic rats induced by yeast was used to prove antipyretic action. The diuresis action was observed by the test. The anti inflammatory effect was observed by pettitoes swelling in rats and auricle swelling in mice. The paper diffuse methods were used to confirm the antisepsis effect. Results: Qinglin Granules not only had the obvious effect of relieving fever and increasing the amount of urine, but also had the strong inhibition on the two kinds of inflammatory models, moreover it can widen the diameter of the antisepsis ring which showed it had the inhibition on cdibacillus, pseudomonas, aeruginosa, bacillus gasoformans, staphylococcus aureus and gonococcic. Conclusion: Qinglin Granules have the obvious antipyretic, diuresis, anti inflammatory and antisepsis effects.

Objective To observe effects of four extracts (water, n-butanol, acetoacetate and petro-leum benzine extracts) from Hippocampus japonicus on kidney-yang deficiency mice induced by extradiol, and reveal the modern scientific connotation about sweet-flavor, warm-nature, meridian tropism in liver and kidney. Methods Kidney-yang deficiency mice was induced by intraperitoneal injection of estradiol benzoate. Effects of four extracts from H. japonicus were observed by measuring physical signs, rectal temperature, grip strength, swimming time, autonomic mobility, creatinine (Cr) and urea (UR) level in serum, haematological indexes, testis index and seminal vesicle index. Results All the four extracts from H. japonicus could markedly improve physical signs and increase seminal vesicle index, RBC, Hb and PLT in blood, and decrease UR level in serum of kidney-yang deficiency mice, water extract and petoleum benzine extract could increase rectal temperature, grip strength, swimming time, autonomic mobility, testis index, WBC, lymphocyte (LY), monocyte (MO), and neutrophilic granulocyte (NE), n-butanol extract could increase autonomic mobility and NE, acetoacetate extract could enhance grip strength and prolong swimming time. Conclusion All above effects of extracts from H. japonicus could be as the basic of improving kidney-yang deficiency, could be an important part of the modern scientific connotation about sweet-flavor, warm-nature, meridian tropism in liver and kidney. Effects of water extract and petroleum ether extract were closer and stronger, which offer enlightenment for searching the common effective substance groups of H. japoniacs.

Objective To investigate the epidemiological characteristics of outpatients exposed to rabies and to analyze the post-exposure prophylaxis in Weinan City in 2017 in order to provide a scientific basis for the prevention of rabies. Methods Clinical data of all outpatients with exposure to rabies in Wei-nan were collected. Ecxcel 2007 was used for data entry and SPSS13. 0 for Chi-square test. Results A total of 32 094 cases were reported with an annual exposure rate of 625. 64/100 000 in Weinan in 2017. Animal bites mainly occurred in spring and summer,accounting for 47. 47% of the total cases in 2017. There were statistically differences in exposure rate among different age groups (χ2=15. 858,P=0. 003). Farmers ac-counted for the largest proportion of the outpatients exposed to rabies (52. 34% ). Among 31 435 outpatients, 28 181(89. 65% ) received wound care and rabies vaccination. The vaccination rate of rabies immunoglobu-lin for patients with gradeⅢ exposure was 46. 93%. Conclusion Comprehensive measures with focuses on compulsory vaccination for domestic dogs and adoption of stray dogs should be implemented to prevent human rabies. Meanwhile,health education rabieson prevention and control should also be strengthened.
