Objective To discuss and analyze clinical pathological characteristics of senile recurrent ovarian cancer and its influences on prognosis.Methods 140 senile ovarian cancer patients who have been admitted in ourhospital were selected as study subjects.103 cases with recurrent ovarian cancer were selected as observation group (group A),and the rest 37 cases who did not suffer from recurrent ovarian cancer were selected as control group(group B).Pathological characteristics of carcinoma tissues after their first admission in our hospital were compared between the two groups.And pathological characteristics of carcinoma tissues of group A after their second admissionin our hospital were analyzed,comprehensively analyzed prognosis situations and clinical pathological characteristics of patients in these two groups.Results In group A,the number of poorly differentiated carcinoma tissues was obviouslymore than group B,and the number of patients whose neoplasm staging was M stage was more than that in group B,the differences between the two groups were significant (x2 =13.48,15.87,all P ＜ 0.05).The incidence rate of adverse reactions between the two groups also had statistical significance(x2 =13.8,11.6,14.5,13.9,14.9,13.4,all P ＜0.05).Conclusion The clinical pathological characteristics of senile recurrent ovarian cancer can reflect patients'prognosis situations in some degree,and has certain clinical value in evaluation of patients' disease recurrence and prognosis.

Objective To analyze the distribution rule of TCM syndromes and syndrome elements in chronic atrophic gastritis with osteoporosis by retrospective study method, and provide evidence for TCM treatment. Methods TCM symptoms, syndromes and syndrome elements of 127 cases of chronic atrophic gastritis with osteoporosis were retrospectively investigated and statistically analyzed. Results The distribution of TCM syndromes in chronic atrophic gastritis with osteoporosis was as follows:there were 51 cases of asthenia syndrome of both qi and yin, accounted for 40.16%;28 cases of yang deficiency syndrome of spleen and kidney, accounted for 22.05%;21 cases of syndrome of qi deficiency and blood stasis, accounted for 16.54%. The distribution of syndrome elements was:there were 82 cases of qi deficiency, accounted for 64.57%;61 cases of yin deficiency, accounted for 48.03%;28 cases of yang deficiency, accounted for 22.05%;21 cases of blood stasis, accounted for 16.54%;12 cases of qi stagnation, accounted for 9.54%;6 cases of dampness-heat, accounted for 4.72%. Conclusion The basic pathogenesis of chronic atrophic gastritis with osteoporosis is deficiency of both spleen and kidney. Deficiency of kidney is mainly qi deficiency, yin deficiency, yang deficiency, or even deficiency of both yin and yang. Reinforcing spleen and kidney is the important principle of treatment.

In clinical and experimental therapeutics, the quantitative analysis of drug interaction will supply a tool for optimizing and evaluating a combination in the study of compound drug, the design of combination drug therapy, and the evaluation of traditional medicine formulae. This paper listed the systematic methods of the quantitative analysis, including the weighted modification method for optimizing constituents, doses and ratio in combination, the parameter method and the reflection method for dynamic analysis of drug interaction, and a comprehensive method for multiple response indexes. The software CoDrug about these methods also was introduced.

Qualitative data are often converted to quantitative data by ranking in pharmacodynamical statistics. Some common questions were listed and discussed with examples in this paper, including ranking method and the selection of statistical method.

Objective To investigate the clinical characteristics of clavicular defect and nonunion after operation and evaluate the clinical effects of vascularized pedicled pectoralis major clavicular periosteal flap and locking plate fixation plus bone morphogenetic protein (BMP) implantation. Methods From January 2004 to April 2008, 12 patients (mean age, 42.8 years old) with clavicular defect and nonunion were treated in Zhongshan Hospital. The internal fixators were removed, and then fibrous scars and sclerotic bones were cleared. The clavicular detects were fixed with locking plate, with implantation of the BMP. The wound was covered with vascularized pedicled pectoralis major clavicular periosteal flap. Postoperative functional rehabilitation exercises were performed. Results All patients were followed up for 8-24 months (mean 1.2 years). The clinical results were evaluated by Constant-Murley scoring system. The clavicular defects were healed in all patients within 4-7 months, and the internal fixators were successfully removed from some of the patients. Conclusions Vascularized pedicled pectoralis major clavicular periosteal flap combined with locking plate fixation plus BMP implantation is effective in the treatment of clavicular defect and nonunion.

Objective To understand adolescent's mental stress, coping style and their correlating with emotion. Methods This research, in order to be tried with 5870 middle school students, adopt Mental Stress Questionnaire, Coping Style Scale and Profile of Mood States. Results Compared with male students, female students had higher scores on stress from school work achievement and appearance(P＜0.05) and lower scores on stress from family[(2.04±1.19)vs(2.11±1.25)](P＜0.05),also they had higher sores on extra-coping style[(3.11±0.77)vs(2.77±0.81)](P＜0.01). Compared with lower grade students, higher grade students had higher scores on all mental stress except stress from family, while they had lower scores on extra-coping style (P＜0.01). Stepwise logistic regression analysis indicated that high scores on mental stress and intro-coping style could predict negative emotion (P＜0.01), and extra-coping style could predict positive emotion (P＜0.01).Conclusion The middle school students suffered more stress from school work achievement than from other aspects. Students who differed in sex, grade had significant different scores on mental stress and coping style. Mental stress and coping style could predict adolescents' emotion.

Objective To observe the expression of phosphorylation of signal transducer and activa -tor of transcription 5 (STAT5) protein and the DNA-binding activity of STAT5 after interleukin 2 therapy for genital herpes .Methods Six patients with recurrent genital herpes were included in this study .CD4 +T cells from patients who underwent interleukin 2 therapy were analyzed for changes in STAT 5 signaling.None had been treated with corticosteroid and immunosuppressive agents .Phosphorylation of STAT 5 was detected in the T cells using Western blot analysis .Electrophoretic mobility shift assay ( EMSA) was carried out to detect the DNA-biding activity of STAT5.Results The expressions of phosphorylated STAT 5 in T cells de-rived from patients with genital herpes 28 days after interleukin treatment were 1.8~2.7 fold to that of be-fore the treatment was given .STAT5 DNA-binding activity in T cells derived form patients with genital her-pes who had received the treatment was 2.3~3.4 fold increased compared to that of before the initiating of interleukin 2 treatment.The differences between the before and after interleukin 2 treatment were statistical-ly significant( t =10.6, P <0.05).Conclusion This study indicates that STAT5 may be an important signaling mediator of interleukin 2 therapies , and that STAT5 activation may predict response to this treat-ment .

A new closed bipolar electrode electrochemiluminescence ( ECL)-based device was designed, and further used to investigate the ECL behaviors of luminol in this device. Our results showed that, while a suitable voltage was applied to the two poles of the closed bipolar electrode, both the positively charged ions and luminol-based anionic ions could be enriched on the two poles of the closed bipolar electrode, respectively. More importantly, the ECL signals, generated from the electro-oxidation of luminol on anodic pole, were found to be related to the total amount of positively charged ions on the cathodic pole of the closed bipolar electrode. Under the optimum experimental conditions, the ECL response was linearly to the concentration of analyte in the range of 1. 0×10-9-1. 0×10-8 mol/L with a detecting limit of 1. 1×10-10 mol/L. Based on this finding, a new ECL method for sensing the solution conductance was developed.
