Objective To discuss the change of androgen level in postmenopausal women with coronal atherosclerosis heart dis-ease,and to discuss its clinical significance.Methods According to the results of coronary angiography,218 cases of possible coro-nal atherosclerosis heart disease patients were divided into the observational group with 93 cases of coronal atherosclerosis heart disease patients,and the control group with non-coronal atherosclerosis heart disease patients.The levels of TC,TG,LDL-C,HDL-C,testostemne and andmstenedione in blood were investigated in two groups.Results The level of blood glucose was not statisti-cally different between the two groups(P >0.05),however,the levels of systolic and diastolic blood pressure,TC,TG,LDL-C and HDL-C were statistically different between the two groups (P < 0.05 ).Conclusion The level of androgen in postmenopausal women with coronal atherosclerosis heart disease are higher than postmenopausal women without coronal atherosclerosis heart dis-ease.Androgen detection is useful for the monitoring and diagnosis for postmenopausal women with coronal atherosclerosis heart disease.

For the cultivation of medical students medical professionalism and evaluation has become a hot is-sue in the medical colleges medical education at home and abroad, but for junior medical students′professional spirit evaluation research is less.This paper introduces the basic concept of responsibility index and application by introducing foreign medical schools responsibility index for evaluation in school doctor students physician profession-alism, analysis the advantages and disadvantages of the method.Think the responsibility index is based on the spe-cific behavior evaluation, the result is more accurate, is suitable for junior medical students′professional spirit e-valuation system, compared with other evaluation system, responsibility index, pay more attention to guidance and specification in advance.But responsibility index also has some disadvantages.Such as responsibility index evalua-tion process must face some ethical challenges, lack of integrity and evaluation framework design.

Ophthalmic imaging including radiographic imaging, acoustic imaging and optical imaging,as a branch of medical imaging has developed rapidly. Optical imaging is very suitable for fundus examination because of the physiological characteristics of the eye. Ophthalmoscope and fundus fluorescein angiography are two historical stages of fundus optical imaging, which become an independent new discipline now, including infrared fundus photography, fundus autofluorescence, fundus fluorescein and indocyanine green angiography and optical coherence tomography. Comprehensive optical imaging plays an irreplaceable role in the diagnosis and treatment evaluation of ocular fundus diseases. Appropriate understanding the principles and significance of various optical imaging methods is very important for their clinical applications.

Under pathologic conditions, nitric oxide causes peripheral insulin resistance by impairing key signal molecules of insulin signaling pathway and mediates dysfunction of islet ? cells caused by lipids, cytokines and hyperglycemia, which plays an important role in the pathogenesis of type 2 diabetes mellitus.

The choline acetyltransferase (CHAT) and the molecular forms of acetyl-cholinesterase (ACHE) activites in various brain regions of 20-day-old hypothyroid and hyper-thyroid rats were measured. The results provided the following information: 1) CHAT and ACHE activities were directly interrelated with thyroid hormones. 2) In both hypothyroid and hyperthyroid rats the nonextractable ACHE activity was distinctly decreased in every brain region, suggesting that both conditions were affected in the critical period of cholinergic synaptic development. 3) The ratio of membrane-bound ACHE to soluble ACHE decreased;it showed that thyroid hormone deficiency might distrub development and maturation of cholinergic neurons. 4) In most regions of the central nervous system,the CHAT seemed to be more affected than ACHE by thyroid hormones.

Objective To explore the therapeutic effect and possible mechanisms of Xuebijing injection for treatment of acute pulmonary thromboembolism(APE)in rabbits. Methods Twenty-four New Zealand rabbits with big ears were randomly divided into control group,model group and Xuebijing group(each n=8). The model of APE was performed by re-infusing of autologous blood clots. After the model was established,in the rabbits of the Xuebijing group,Xuebijing injection 1 mL/kg was injected into the ear marginal vein,twice daily for consecutive 7 days. In the model and control groups,the same amount of normal saline was given via the same route. The changes in plasma levels of B-type natriuretic peptide(BNP)were detected by enzyme-linked immunosorbent assay(ELISA) at the time points of 8 hours and 1,3,5,7 days,and after 7 days the lungs of the rabbits were removed for the lung histopathological examination. Results The BNP levels of the model group and Xuebijing group were significantly higher compared with the level of control group at 8 hours after embolization,the model group being the most significant(all P<0.05). On day 3,the BNP levels of the model group and Xuebijing group reached their peaks,and then gradually decreased,but the level of model group was significantly higher than that of Xuebijing group(ng/L:581.1±144.6 vs. 251.5±22.5,P<0.05). On day 7,the BNP level of Xuebijing group fell to the level of the control group(ng/L:78.5±9.4 vs. 50.9±11.5),the level of the model group also decreased,but it was still much higher than that of the Xuebijing group(ng/L:214.1±47.6 vs. 78.5±9.4,P<0.05). Histopathological examination showed Xuebijing could significantly reduce the infarct size with mild inflammatory cell infiltration,but the infarct size of the model group was obviously bigger than that of the Xuebijing group and accompanied by relatively more inflammatory cell infiltration. Conclusion Xuebijing injection can significantly reduce the plasma BNP level of the rabbits with pulmonary embolism,and in the mean time ameliorate the degree of inflammatory infiltration in the lung tissue and infarct.

BACKGROUND: With the continuous renewal and development of clinical repair techniques, the intraoperatie blood loss has been greatly reduced in the treatment of intertrochanteric fracture; however, no matter what kind of repair methods should be adopted, there are stil a large amount of perioperative hidden blood loss, however, there are few clinical reports for the reasons and related factors. OBJECTIVE: To study the correlation of perioperative hidden blood loss with gender and internal fixation methods in the surgery of elderly femoral intertrochanteric fractures.METHODS: Total y 121 patients with elderly femoral intertrochanteric fractures who received the treatment at Department of Orthopedics, Nanyang City Center Hospital from March 2010 to June 2013 were divided into two groups according to the condition and treatment wishes of patients, and were respectively treated with dynamic hip screw and proximal femoral anti-rotation intramedul ary nail internal fixation. The preoperative hidden blood loss, postoperative hidden blood loss, the total hidden blood loss, dominant blood loss and total blood loss of patients in these two groups were compared. The multiple linear regression analysis on the correlation of perioperative hidden blood loss with gender and internal fixation methods was conducted. RESULTS AND CONCLUSION: There was no significant difference in the preoperative hidden blood loss between these two groups (P > 0.05). The total blood loss, postoperative hidden blood loss and total hidden blood loss in the proximal femoral anti-rotation intramedul ary nail group were significantly higher than those in the dynamic hip screw group (P < 0.05), and the dominant blood loss was significantly lower than that in the dynamic hip screw group (P <0.05). There were significant differences in the preoperative, postoperative hidden blood loss and total hidden blood loss between males and females (P < 0.05), and above indexes in males were significantly lower than in females. The multiple linear regression analysis showed that gender and internal fixation methods were correlated with hidden blood loss (P < 0.05). These results suggest that the perioperative hidden blood loss in surgery for elderly femoral intertrochanteric fractures is closely related to gender and above indexes in internal fixation methods. The perioperative hidden blood loss of male patients is less than that of female patients, and the patients treated with proximal femoral anti-rotation intramedul ary nail fixation have more hidden blood loss than dynamic hip screw fixation.
