Objective To discuss the relationship age and pathologic type, tumor size (≥4 cm) and pelvic lymph metastasis in cervical cancer, and the relative factors of cervical cancer with metastasis of pelvic lymphaden and the possibility of ovarian conservation. Methods 166 cases of cervical cancer accepted radical hysterectomy and pelvic lymphadenectomy in our hospital from June 2002 to June 2007, and were analyzed retrospectively. 166 cases of cervical cancer were divided into two groups, the age in group A was less than 35, while in group B was more than 35. Results The possibility of adenocarcinoma, the tumor size (≥4 cm) and the metastasis of pelvic lymphaden were higher in group A than in group B. The higher the clinical stage, the higher the pathological type and grade were. The greater the tumor size were ,the higher the rate of pelvic lymphatic metastasis (P <0.01). The more tissue infiltrate were, the higher the rate of pelvic lymphatic metastasis (P <0.01). Conclusion The possibility of adenocarcinoma carcinoma, the tumor size (≥ 4 cm) and the metastasis of pelvic were more higher in young women. The rate of pelvic metastasis is closely related to clinical stage, pathological type and grade, tumor size, and tissue infitration.

Objective:To investigate the amplification of the telomerase RNA component (TERC) gene in cervical cancer and cervical intraepithelial neoplasia (CIN) using dual-color interphase fluorescence in situ hybridization (FISH) and its significance in screening of cervical lesion. Methods:Cervical cast-off cell specimens were screened from 120 outpatients with cervical lesion, including normal cell from liquid based cytology (20 cases), CIN Ⅰ , Ⅱ , Ⅲ and cervical cancer cell from liquid based cytology (each of 25 cases). The amplification of TERC gene in cervical cast-off cells was detected by dual-color interphase FISH. The results of normal samples were used to set up the threshold. Results:①The percentages of abnormal cells in CIN Ⅰ , Ⅱ , Ⅲ and cervical cancer were significantly higher than threshold value ( P<0.05), and the percentage of abnormal cells was increased with the serious degree of pathological grade (P<0.01) ; ②The percentagesof 2:3,2:4,2:5 and great than or equal to 4:4 types in CIN Ⅰ , Ⅱ , Ⅲ and cervical cancer were significantdifferences (all P<0.01). The percentages of 2:4,2:5 and great than or equal to 4:4 types in cervical cancer were significant higher than that in CIN Ⅰ (P<0.001) while the percentage of 2:3 type was significant lower than that in it (P<0.001);③The percentage of abnormal cells was increased with the serious degree of cytological grade (P<0.01) in different cytological grades. The percentages of 2:3,2:5 and great than or equal to 4:4 types in atypical squamous cell of undetermined significance (ASCUS), low-grade squamous intraepithe-lial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL) were significant differences (all P <0.01), and the percentages of 2:5 and great than or equal to 4:4 types in HSIL were significant higher than that in ASCUS( P <0.01) while the percentage of 2:3 type was significant lower than that in it ( P <0.01);④The detection rates of LSIL and HSIL with cytological examination in low grade and high grade CIN were 40% (10/25) and 62% (31/50) respectively, which were significant lower than the detection rates of FISH which was 100%(P<0.05).Conclusions:There is an abnormal amplification of TERC gene in CIN Ⅰ , Ⅱ , Ⅲ and cervical cancer, and its copy numbers are increased with the serious degree of pathological and cytological grades. Detection of amplification of TERC gene in cervical cast-off cells with FISH has a certain value for screening cervival lesion and prediction of lesion progression.

Objective To evaluate the value of cardiovascular digital imaging and echocardiography in diagnosis of transposition of the great arteries.Methods Thirty cases of transposition of the great arteries were examined with cardiovascular digital imaging technique,two-dimensional echocardiography and color Doppler.11 cases of them underwent surgery.A comparison was made between the data obtained and surgical findings.Results The rate of coincidence of digital imaging and echocardiography with operation in diagnosing transposition of the great arteries was 92.3%(36/39)and 84.6%(33/39) respectively.Both echocardiography and cardiovascular digital imaging techique could clearly show the abnormalities of the heart and great vessels.Echocardiography was sensitive to valvular pathological changes,though cardiovascular digital imaging was superior to echocardiography in demonstrating abnormalities of great arteries and systemic-pulmonary collateral circulations.Conclusion Combination of echocardiography with cardiovascular digital imaging technique can greatly improve the rate of diagnostic accuracy for transposition of the great arteries.

OBJECTIVE: To summarize and analyze the characters, pathogenesis and influencing factors of various tremors, so as to provide evidence for the identification, prevention and treatment of various tremors in clinic.DATA SOURCES: A computer-based online search of Medline database was undertaken to identify articles about tremor published in English between January 1998 and May 2005 with the keyword of "tremor". Meanwhile, Chinese relevant articles published between January 1998 and May 2005 were searched with computer in Chinese full-text journal net by using the keyword of "tremor" in Chinese. STUDY SELECTION: The data were primarily checked. Inclusive criteria: ① articles about the classification, etiological factors and influencing factors of tremor; ② retrospective investigation on specific events. Exclusive criteria: repetitive studies.DATA EXTRACTION: Totally 48 articles were collected, and 31 repetitive studies were excluded. Of the other 17 ones accorded with the inclusive criteria, 9 were the investigations about tremor, and 8 were the specific cases of tremor.DATA SYNTHESIS: Tremor is classified mainly according to its manifestations and the etiological factors of basic disease. Mechanical tremor,reflexion of central nervous system and central oscillator are the pathogenesis of tremor. According to the manifestations, tremor canbe classified into static tremor, kinetic tremor, essential tremor, postural tremor, unfixed tremor. According to the different etiological factors, tremor can be classified into enhanced physiological tremor, essential tremor syndrome (classical essential tremor, orthostatic tremor, task-specific tremor, undetermined tremor), dystonic tremor, cerebellar tremor, Holmes tremor, peripheral neuropathic tremor, drug-induced and toxic tremor and psychogenic tremor,and different treatments should be adopted according to different etiological factors in clinic.CONCLUSION: Tremor has similar manifestations, but the pathogenesis are different, so different treatments should be adopted according to different etiological factors in clinic.

BACKGROUND: In China, diabetic patients suffer from various chronic complications with a higher prevalence, which is nearly close to that in developed countries. Especially in Xinjiang, the prevalence is much higher than the average level, and the level of disease control is very poor as a whole.OBJECTIVE: To study the actuality of controlling type 2 diabetes mellitus in Xinjiang so as to analyze its relationship with disease courses.DESIGN: Cluster sampling and stratified analysis.SETTING: Department of Endocrinology, Xinjiang General Hospital of Chinese People's Armed Police Forces.PARTICIPANTS: The survey was conducted at ten treatment centers of Xinjiang(the First Affiliated Hospital of Xinjiang MedicalUniversity, People's Hospital of Xinjiang Uigur Autonomous Region, Urumchi Hospital of Air Force of Chinese PLA, Railway Hospital of Xinjing Uigur Autonomous Region, Military Unit Hospital of Xinjiang, Kuitun Central Hospital of Yili Region of Xinjiang, Kelamay People's Hospital of Xinjiang, Kuler People's Hospital of Xinjiang, the First Division Hospital of Xinjiang Military Unit for Produce and Building, Xinjiang Hospital of Traditional Chinese Medicine). Totally 646 type 2 diabetic patients who had received treatment for diabetes mellitus for 12 months, at any of the centers were randomly recruited with cluster sampling method including 337 males and 309 females. According to different courses of disease, the subjects were divided into 6 groups: 202 cases in group of ＜ 3 years, 89 in group of 3-4 years,89 in group of 5-6 years, 77 in group of 7-9 years, 108 in group of 10-14years, and 81 in group of ≥ 15 years. All the subjects agreed to participate in the survey.METHODS: Patients detected their blood sugar level and urine sugar level themselves with portable diabetograph and test paper. For them, there were at least four days per week to take diabetic diet which was considered as common diet control, and there were at least three days per week to participate in leisure activity and at least half an hour per day to spend in proper exercise which was considered as frequent exercise. Complications of diabetes mellitus were diagnosed with clinical manifestation, disease history and objective examination. The survey was performed through letter,telephone counseling, and patient's reexamination. Enumeration data was analyzed with chi-square test.MAIN OUTCOME MEASURES: Differences in blood sugar, urine sugar, management of living style, prevalence of complications in all the diabetic patients with different courses of disease.RESULTS: There were 645, 645, 643, 646 patients with complete data of blood sugar and urine sugar determined periodically at home, participated in the observation of the management of living style, prevalence of diabetic complications and treatment for diabetes mellitus, respectively. ①There was no significant difference in blood sugar and urine sugar level deter mined at home every month among patients of different courses (P ＞ 0.05). ② There was no difference in diet control and exercise among patients of different courses (P ＞ 0.05). ③In patients with disease course of ＜ 15 years, prevalence of the complication in large vessels and extremity,retinopathy, and positive expression of proteinuria presented an increased tendency; whereas, a decreased tendency was found in patients with the disease course of ≥ 15 years(χ2=34.16,60.64,49.18,P=0.00). ④The proportion of applied therapies, such as diet control and exercise, oral antidiabetic drug, insulin, and insulin plus oral anti-diabetic drug, was different in patients with different disease courses (χ2=97.88 ,P=0.00). In patients with short disease courses, diet control or oral anti-diabetic drug was administrated more usually; in those with long disease courses, insulin treatment or insulin plus oral anti-diabetic drug was applied more frequently.CONCLUSION: ①Whether patients determine their blood sugar and urine sugar levels by themselves is not correlated with patients' disease courses. ②Diet control and exercise are not in correlation with disease courses. ③ For patients with the disease course of less than 15 years, the proportion of prevalence of various diabetic complications is increased with the increase of disease courses; for those with the disease course of more than 15 years, however, it is decreased significantly. ④Simple diet control or oral anti-diabetic drug is often applied in patients with short disease courses while insulin or insulin plus oral anti-diabetic drug are administrated in most patients with long disease courses.

Calmodulin-dependent protein kinase (CaMK), activated by auto-phosphorylation at the presence of calcium and calmodulin, is widely distributed in eukaryotes. CaMKs are important mediators of calcium signal in eukaryotes. Recent researches have suggested that CaMKⅡ is involved in the regulation of meiotic cell cycle of oocytes. It plays functional roles in meiotic maturation, polar body extrusion, fertilization and egg activation. As one of the down-stream signaling molecules of calcium, CaMKⅡ facilitates the inactivation of maturation promoting factor (MPF) and cytostatic factor (CSF) following fertilization, as well as the spindle microtubule organization and centrosome duplication. Although the functions of CaMKⅡ in oocyte meiosis are versatile and essential, the present results are primarily obtained from low vertebrates and mouse. In future studies, the function and regulation of this kinase in other mammals should be stressed.
