35u/ml as positive limit, the sensitivity of CA125 for diagnosis of lung cancer is 53.6%. There was no significant difference between stage Ⅰ,Ⅱ lung cancer and benign, healthy groups, but the level of serum CA125 of stageⅢ?Ⅳ was higher than control groups. Thirty eight of forty lung cancer patients with higher CA125 level dropped to normal after therapy. Conclusions:Serum CA125 has high diagnosis value in lung cancer. It can be a vital index in lung cancer staging and prognosis.

After screening,the authors established a mouse model of pathomorphologically special,transplantable mammary spindle cell carcinoma SCC 891 in BALB/c mice.After 48 passages in 2.5 years,the growth of the tumor strain became stable with a 100% transplantibility.Its growth was quite active without observable spontaneous regression.The mean life span of the host mouse was 35.2?7.3 days.BALB/c mice of both sexes and of any age were susceptable to the carcinoma,and the carcinoma was sensitive to various anticancer drugs.

Objective To compare the isometric muscle strength of muscle groups in the lower extremities of children with spastic hemiplegia among sides or ages. Methods17 spastic hemiplegic children were measured the muscle strength of hip, knee and ankle muscle groups with hand-held dynamometry (HHD). ResultsMuscle strength was weaker in the involved side than in the other side. In younger children, it was weaker of overall extremity, while in the older it was of the distal end mainly. ConclusionWhen applying strength training to spastic hemiplegic children, it is important to notice strength of all groups in lower extremity in younger children and the distal groups in older ones.

Objective To investigate the relationship of the anti-inflammatory effects of tetramethylprazine with histamine and 5-hydroxytryptaphane(5-HT).Methods The contents of histamine and 5-HT in the inflammatory exudate of rats were determined by fluorescence technique.The effect of tetramethylprazine on histamine and 5-HT were analyzed by in-vitro ileum contraction test in guinea pigs.Results Tetramethylprazine significantly decreased the contents of histamine and 5-HT in the inflammatory exudate,and markedly antagonized the contraction of isolated ileum induced by histamine and 5-HT.Conclusion The anti-inflammatory mechanisms of tetramethylprazine may be related to the inhibition of the synthesis or release of histamine and 5-HT,as well as its direct antagonism.

Objective To evaluate eutopic endometrial blood supply and vessels in patients with endometriosis(EMs) with contrast enhanced ultrasound (CEUS),to explore a newmethod to estimate vascularization of eutopic endometrium in EMs patients.MethodsThirty patients with EMs were enrolled and 20 patients who were diagnosed as other gynecological diseases as control.Informed consent of each case was obtained. AllcasesunderwentconventionalultrasoundexaminationandCEUSexamination.Characteristics of CEUS in each patients were observed and analyzed using off-line Qontrast software.Parameters of CEUS including peak intensity(PEAK),time to peak(TTP),regional blood volume(RBV),regional blood flow(RBF) were obtained automatically.ResultsComparing with control group,the eutopic endometrium in EMs group presented higher enhancement.The parameters of CEUS,including PEAK,TTP,RBV,RBF were (41.18 ± 3.29) dB,(29.01 ± 4.46) s,(29.07 ± 4.59) ml,(48.61 ± 5.35) ml/min in EMs group and (13.36 ± 2.34)dB,(24.59 ± 2.29)s,(26.51 ±- 3.80)ml,(48.71 ± 3.80)ml/min in controls respectively,the value of PEAK in EMs group was higher than that of controls ( P =0.000).Conclusions CEUS can be regarded as a new method which can be used to assess vascularization of eutopic endometrium in endometriosis.

Objective To investigate etiology and clinical features of acute pancreatitis (AP) in young patients. Methods In total, 423 patients with AP admitted to Renmin Hospital of Wuhan University, Wuhan, Hubei province during January 2006 to December 2009 were retrospectively analyzed, 55 cases aged 34 years or less as young group and another 55 cases aged more than 34 years as middle- and elderly-age group. Their etiology, clinical features and illness scores based on some standard criteria were assessed. Results Proportion of varied etiologies of AP in young group was different from that in middle- and elderly-age one (x2 = 17. 107, P = 0. 009) , mainly as biliary and idiopathic pancreatitis in young group and as biliary and alcoholic pancreatitis in middle- and elderly-age one. Incidence of diet-related and idiopathic pancreatitis were higher in young group than that in middle- and elderly-age one ( x2 =4. 853, P = 0. 028 and x2=4. 274, P = 0. 039 ). Scores of the acute physiology and chronic health evaluation II ( APACHE II ) , Ranson criteria and the bedside index for severity in acute pancreatitis ( BISAP) were all lower in young group than those in middle- and elderly-age one (t = 5. 381 , P = 0. 000; t = 4. 388 , P = 0. 000 and t=3. 083, P = 0. 003 ) . There was no statistically significant difference in scores of computed tomography severity index ( CTSI) between young group and middle- and elderly-age one (t = ±0. 750, P > 0. 05 ) . Recurrence rate of AP was lower in young group than that in middle- and elderly-age one ( x2 =4. 251, P = 0. 039). Cholecystitis was more complicated in young group, pregnancy was more complicated in young group (x2 =4. 151 , P =0. 042) , and elevated blood glucose was more complicated in middle- and elderly-age one (x2 = 13. 285 , P = 0. 000 ) . Conclusions Etiology of AP varies in young patients with more dietary factors, occurrence of systemic complications and risks for death are lower in young group than those in middle- and elderly-age one, and there was no statistically significant difference in local complications and severity of illness between the two groups.

In order to assess the feasibility of subcutaneous administration of Triptorelin with 6-week intervals for the suppression of pituitary-gonadal axis and changes of clinical signs in girls with idiopathic central precocious puberty (ICPP), 46 girls with ICPP were treated with GnRHa. Triptorelin (Decapeptyl, 3.75 mg) was administered subcutaneously (SC) at 6-weeks intervals or intramuscularly (IM) at 4-weeks intervals randomly for more than 12 months consecutively. During GnRHa therapy, clinical parameters and laboratory data, including height, weight, pubertal stage, bone age, uterine volume and ovarian size, serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH) and estradiol (E2), were monitored and analyzed. It was found that both treatment regimes led to regression of precocious puberty and reversal of secondary sexual characteristics. Breast developments regressed. Uterine volume was decreased after treatment, but there was no statistically significant difference. Mean ovarian volume did not change significantly during treatment. The height velocity was decreased significantly from 6.3+/-1.4 cm/year to 5.8+/-1.2 cm/year in group SC and 6.7+/-1.3 cm/year to 5.4+/-1.0 cm/year in group IM, respectively. The rate of bone maturation was reduced significantly during treatment. The ratio of deltaBA/deltaCA was 1.2+/-0.2 or 1.3+/-0.3 at the onset of therapy and decreased significantly after the treatment to 0.7+/-0.2 or 0.9+/-0.1, respectively. The predicted adult height was increased significantly and progressively during therapy. The levels of serum LH, FSH and E2 returned to the prepubertal condition. No significant side effects of therapy were noted. The most common side effect during SC treatment was that a non-irritating, 1 cm in diameter mass was palpated at the site of subcutaneous injection in the abdominal wall of patients, which disappeared after 6-12 weeks. Two girls had minimal withdrawal vaginal bleeding episodes after the first injection. It was concluded that both IM and SC triptorelin administrations were clinically effective. They induce profound suppression of hypothalamic-pituitary-gonadal axis while stabilizing height velocity, slowing bone maturation and increasing predicted adult height. These results suggest that subcutaneous injection of triptorelin in 6-weeks intervals at a dosage of 3.75 mg be a safe and acceptable regimen for ICPP
