Objective To analyze the trend of cervical cancer, age structure and influencing factors. Methods Retrospective study and survey. The 1563 patients with cervical cancer and gynecological medical examination of 600 non-cervical cancer patients who took part in Physical examination in the obstetrics and gynecology department received the enclosed analysis questionnaire. Results Cervical cancer is becoming a trend of cervical cancer patients being younger, high risk period at the age of 36 to 55, and the downward trend towards the menopausal women. The number of being pregnant, ma]-sexuality (the first sexual intercourse at a younger age, or many sexual partners), and smoking are the causes which lead to cervical cancer. Conclusion Give great importance to a trend of cervical cancer patients being younger; screening, publicity and education about cervical cancer;, missionaries and strengthen anti-cancer awareness, promote a healthy lifestyle, which is the key to prevention and treatment of cervical cancer.

Objective To study the effects of choline chloride on activities of myosin adenosine triphosphatase (mATPase) of muscle fibres and muscle atrophy in tail-suspended rats. Method Twenty-four adult female Sprague-dawley rats were averagely divided into 3 groups matched for body mass:control group(CON),tail suspension group(TS) and tail suspension group associated with choline chloride(TS+Cch).Weightlessness was simulated by 14 d tail suspension of rats;gastric lavage with choline chloride was given to 1/2 of the rats during tail suspension (15 mg/kg body weight.i.g.).Activities of myosin adenosine triphosphatase (mATpase) of intrafusal and extrafusal fibres in soleus (SOL) muscle were determined by Ca 2+-ATPase method.Paraffin sections of the soleus muscle were prepared by routine histochemistry method. Result After tail suspension for 14 d it was found: 1) percentage of type Ⅱ fibre in SOL of rats treated with choline chloride decreased distinctly as compared with that in the untreated rats (P
