Objective To observe the influence of clopidogrel combined with proton pump inhibitor (PPI) on the postoperative complication of percutaneous coronary intervention.Methods The clinical data of 600 patients who were taking clopidogrel antiplatelet therapy were retrospectively analyzed.All patients were divided into observation group (with PPI,n =300) and control group (without PPI,n=300).In-stent restenosis (ISR) and the adverse event rates were compared between the two groups during the period of follow up.Results The incidence of gastrointestinal bleeding was less in observation group than in control group (6.7％ vs.13.7％,x2 =8.048,P＜0.01),but the incidences of ISR,target vessel revascularization (TVR) and non-fatal myocardial infarction were higher in observation group than in control group(x2 =6.426、5.511、4.718,all P＜0.05).Conclusions Clopidogrel combined with PPI treatment can significantly reduce the risk of gastrointestinal bleeding,but increase the incidences of major adverse cardiovascular events.We suggest that PPI should be used with caution for the patients who need longer-term PPI use.

Objective To analyze the characteristics of magnetic resonance imaging(MRI)and DWI in newly diagnosed patients with cervical cancer,and to investigate the correlation between the clinical pathological features and the clinical pathological characteristics.Methods 100 cases of newly diagnosed cervical cancer were selected as the research subjects.All patients received magnetic resonance plain scan,DWI examination,MRI features of cervical carcinoma were observed,its ADC value and MVD were measured,ADC and MVD in different stages of cervical cancer were compared,its correlation was analyzed.Results The signal features of the lesions were as long as T2 , slightly longer T1 signal.The pressure sequence was obviously high signal.Compared with the surrounding tissue,DWI sequence was high signal.In the diagnosis and staging of Ⅲ and Ⅳstage lesion,the MRI diagnosis was right,MRI of the 9 cases of Ⅱstage lesion was misdiagnosed as Ⅰstage lesion,7 cases of Ⅰstage lesion were misdiagnosed as Ⅱstage lesion,compared with the postoperative pathologic staging,the diagnostic accuracy was 84%.There were signifi-cant differences in ADC value[(0.917 ±0.055)s/mm2 vs.(0.911 ±0.044)s/mm2 vs.(0.887 ±0.047)s/mm2 vs. (0.815 ±0.043)s/mm2 ]and MVD[(27.38 ±5.66)vs.(29.54 ±7.32)vs.(34.46 ±8.92)vs.(35.26 ±8.84)] between different stages of cervical cancer(F =3.024,2.941,all P <0.05),The ADC value of cervical carcinoma inⅢ and Ⅳstage lesion was significantly lower than that of the Ⅰ and Ⅱstage lesion of cervical cancer,MVD was significantly higher than that of the Ⅰ and Ⅱstage lesion of cervical cancer,the differences were statistically signifi-cant(t =2.992,2.976,3.954,3.689,all P <0.05).By Pearson correlation analysis,significantly negative correlation was found between ADC value and MVD value of cervical cancer(r =-0.678,P =0.021).Conclusion The MRI and DWI images of cervical carcinoma are characteristic,there was a significant correlation between clinical stage and MVD.

Objective To investigate the expression of ACTH in normal and hyperplastic adrenal cortical tissue, and to explore the relationship between plasma ACTH concentration and expression level of ACTH in adrenal cortical tissue of patients with adrenal cortical hyperplasia. Methods The expression of ACTH in adrenal cortical tissue was examined by immunohistochemical technique, and the result was analyzed by computer-assisted image analyzing system. Besides, plasma ACTH concentration was measured by RIA. The correlation between plasma ACTH concentration and expression level of ACTH in adrenal cortical tissue of patients with adrenal cortical hyperplasia was studied. Results The expression of ACTH was significantly higher in adrenal cortical tissue of patients with ACTH-independent adrenal cortical hyperplasia than those with ACTH-dependent adrenal cortical hyperplasia and normal adrenocortical tissue (both P0.05). Conclusion ACTH expression exists in normal adrenal cortical tissue. Local ACTH overproduction appears to participate in the pathogenesis of ACTH-independent adrenal cortical hyperplasia.The raised concentration of plasma ACTH influences the expression of ACTH in cortical tissue of patients with ACTH-dependent adrenal hyperplasia.

Objective:To detect the expression of cyclin D1 protein and Rb protein in breast cancer and analyze its relationship to carcinogenesis and development.Methods:The expression of cyclin D1 and Rb protein were detected in 52 breast cancer and 20 benige breast tissues by S-P immunohistochemical method.Results:The positivity rate of cyclin D1 overexpression in the breast cancer was 34.6%(18/52),while there was a significant difference compared with that of benign breast tissues 10%(2/20),P

Compressive cervical myelopathy (CCM) is a common disease of spinal surgery. Various kinds of reasons such as herniation of cervical disc and ossification of the posterior longitudinal ligament (OPLL) lead to spinal canal stenosis, thereby compressing the spinal cord, and a series of neurological symptoms are caused. Currently, posterior cervical expansive open-door laminoplasty (PCEOLP) is widely used for cervical decompression in patients with CCM involving three or more levels. This operation can expand the spinal canal while preserving the posterior structures of the cervical spine, and non-neurological complications are relatively rare. However, there are characteristic complications to this procedure such as nerve root palsy, axial neck pain, and loss of range of motion (ROM). Various modified techniques of PCEOLP have been developed to reduce postoperative complications. In this review, clinical research progress of PCEOLP in recent years is summarized, mainly focusing on internal fixation of materials and methods, operative approach, cervical decompression level, combined application of different surgical procedures, opening size and application of new technologies.

OBJECTIVE:To provide reference for improving the pharmacy self-taught undergraduate course system in general universities in China. METHODS:According to comparative study and researching related literatures,the situation of pharmacy self-taught undergraduate course system in general universities in China was analyzed,and reform ideas and programs were present-ed. RESULTS & CONCLUSIONS:Based onchemistry-biology-psychology-society-medicine-pharmacyin the overall framework of pharmacy undergraduate self-examination course system,it was designed with target of cultivating applied talents;related con-tents in public basic courses,humanities basic course and professional ethics course should throughout the whole teaching process;professional main course should be pharmaceutical knowledge-based,supplemented by medical related courses;the school should set vocational elective course to reform based on combining with the own teaching research direction,characteristics and career ori-entation of different self-taught students. The reform can develop applied talents with ability and political integrity,which meets the needs of social development.

As a newly identified T helper cell subset, Th9 plays an important role in anti-tumor immunity. Th9 can be differentiated from CD4+T cells that have been induced by TGF-beta and IL-4. In addition, other CD4+T helper cell subsets can be developed to Th9 cell in particular situations, thereby showing its plasticity. Results of animal experiments have indicated that Th9 inhibits tumor growth and plays a significant role in anti-tumor immunity by secreting related cytokines such as IL-9. A few cytokines and molecules can regu-late the differentiation and development of Th9 cells in different signaling pathways. This review will focus on the production, anti-tu-mor immunity, related mechanism, and signaling pathways of Th9 cells, thereby providing a new field of vision and idea for anti-tumor therapy in the future.
