Objective To explore application of preoperative examination in the colorectal cancer patients. Methods The preoperative examination data of patients diagnosed definitely as colorectal cancer at West China Hospital of Sichuan University from November 2006 to June 2007 was retrospectively study, and the application situation and relationship among all preoperative examination in the colorectal cancer patients were analyzed. Results According to the inclusion criteria, 438 colorectal cancer patients were included which involved 260 males and 178 females. Preoperative examinations included two to sixteen items, with an average of 10.61 items. According to correlation analysis, positive correlation existed among lung function and blood type ( r =0.161, P =0.001), tumor marker ( r =0.118, P =0.014), chest X-ray ( r =0.113, P =0.018), routine electrocardiogram ( r =0.198, P =0.000) , while lung function and immune and stress reaction exhibit a negative correlation ( r =-0.106, P = 0.027) with preoperative examinations. At the same time, immune and stress reaction had positive correlation to CT examinations of abdomen ( r =0.151, P =0.001) as well as endorectal ultrasound ( r =0.330, P =0.000). Using univariate analysis, the influence of tumor location ( P =0.012) and operative method ( P =0.004) on the number of examination items was significant. Conclusion Preoperative examination of colorectal tumor surgery mainly includes routine examination, neoplasm-related examination and important organs function detection. And three levels of preoperative menu can be set up in early stage. Establishment of normalization preoperative combined examination may be helpful to consummate preoperative evaluation and improve medical quality.
Objective To summarize the diagnosis and treatment of Hashimoto thyroiditis （HT） coexistence withthyroid cancer （TC）. Methods One hundred and eighty-four patients with HT treated in The Affiliated Hospital of Guiyang Medical College from Jan. 2008 to Dec. 2011 were collected， and clinical data of 32 patients with TC of them were analyzed retrospectively. Results Thirty two patients combined with TC of the 184 patients with HT， and the incidence rate was 17.4%. All of the 32 patients were treated surgically according to the principle of surgery treatment for TC. Of the 32 cases of HT coexistence with TC， 15 patients were diagnosed by preoperative fine needle aspiration cytology （FNAC）， and the sensitivity of FNAC was 46.9% （15/32）. Twenty seven patients were diagnosed by intraop-erative frozen section pathological examination， and the sensitivity of it was 84.4% （27/32）， which was significantly higher than those of FNAC （χ2=7.563，P=0.004）. Thirty patients were diagnosed as papillary thyroid carcinoma （PTC）， and 2 patients were diagnosed as follicular thyroid carcinoma （FTC） by postoperative paraffin section pathological exam-ination and （or） immunohistochemistry， respectively. All patients were treated with levothyroxine （L-T4） after operation，and 5 patients were treatment with 131I therapy in addition. One patient suffered convulsion， and 2 patients suffered mild hoarsenessthere after operation. Only 29 patients were followed up for 3-49 months （average 35 months）， and during the followed up， there were no tumor recurrence， metastasis， and death. Conclusions The rate of preoperative diagnosis of HT coexistence with TC is low， and auxiliary examinations play an important role in diagnosis and guiding treatment. Surgery is the preferred treatment， but auxiliary therapies after surgery are indispensable too.
Uveitis is a group of inflammatory diseases affecting the uveal tract, retina, retinal blood vessels and vitreous. Due to its complex etiology, various entities, diverse and lack of constancy in treatment, some patients can experience visual impairment and even loss. In view of the fact that blindness caused by uveitis is mostly incurable and occurs usually in young and middle-aged people, it accounts for an important part of blinding eye diseases and has attracted worldwide attention. With the continuous development of precision medicine, clinicians will face new problems and challenges in disease diagnosis, and further in-depth research is needed to explore more optimized and efficient diagnostic processes and examinations to improve the diagnosis of uveitis in China.
