一、引言咳嗽多为附属于某种疾病之一种症状,凡合并有其它主症的,只須治其主症,而咳即随之消失,斯固无須独立为一病者。本文所謂慢性咳嗽,系指較长期之頑固咳嗽,而以咳为主症,且有反复发作或季节性发作病史者,相当于西医所称慢性支气管炎。西医对慢性支气管炎的治疗,一般不够理想,我院根据中医辨症治疗之原則,采用中医中药治疗,疗效尚称滿意,现将本人对本病分型治疗的体会,初步汇报如下:  相似文献

Objectives To investigate the prevalence of sinonasal lymphoepithelial carcinoma (SNLEC) in Guangzhou, a high incidence area of nasopharyngeal carcinoma (NPC), and to dete ct whether it is associated with Epstein-Barr virus (EBV) infection. Methods Twenty confirmed SNLEC specimens were collected from all of the sinonasal carcin oma biopsies performed in the 8 years 1989-1996 at the Sun Yat-sen University o f Medical Sciences. EBV encoded early RNAs were detected by use of in-situ hyb ridization. A variety of antigens, including the EBV nuclear antigen 1, latent membrane protein 1, BZLF1 protein, diffuse early antigen, viral capsid antigen a nd membrane antigen, were detected using immunohistochemistry. Additionally, 36 NPC specimens were used for comparison. Results Twenty SNLECs were identified. Seventeen SNLECs were developed in the nasal cav ity, and 3 in the maxillary sinus. The mean age (46.25 y), male to female ratio (3∶1), histopathology and lymphoinfiltration of the 20 SNLECs were id entical with those of the 36 NPCs. Thirteen (65.0%) of the 20 SNLECs showed an expansive growth pattern, while 27 (75.0%) of the 36 NPCs showed an infiltrat ing or mixed growth pattern. The majority of cancer cells in all of the 20 SNLE Cs showed EBV encoded early RNAs. The EBV nuclear antigen 1 expression of SNLEC was less intensive than that of NPC. The expression rate of latent membrane pr otein 1 for SNLEC (3/20,15%) was lower than that for NPC (19/36, 52.8%). The e xpression rates of BZLF1 protein (2/20, 10.0%), diffuse early antigen (19/20, 9 5.0%), viral capsid antigen (15/20, 75.0%), and membrane antigen (13/20, 65.0 %) for SNLEC were higher than those (0/36, 0.0%; 31/36, 86.0%; 18/36, 50%; and 14/36, 38.9%) for NPC. Conclusions SNLEC is not uncommon in Guangzhou. This tumour is also consistently associated with EBV infection like NPC. As compared to NPC, the EBV harbored in SNLECs s eems to express the EBV nuclear antigen 1 weakly and has a lower expression rate of latent membrane protein 1 as well as higher expression rates of EBV lytic pr oducts.  相似文献
