Objective To investigate the influence of fast track surgery on stress and inflammatory re-sponse in breast cancer patients treated with modified radical mastectomy .Methods Ninety nine patients with breast cancer undergoing modified radical mastectomy were allocated randomly to fast track surgery group (46cases)and general group(53cases).The concentrations of serum PRA,Ang-Ⅱ,ALD,cortisol,IL-6,IL-8,TNF-αof each group were measured before operation ,12 hour,24hour and 48hour after operation by radioim-munoassay method.Operation time,operative blood loss and hospitalization days were analyzed between the two groups,simultaneously ,the incidence of subcutaneous hydrops ,flap necrosis and upper limb edema were also de-tected.Results The concentration of serum PRA ,Ang-Ⅱ,ALD,cortisol,IL-6,IL-8 and TNF-αwere no significantly differences in two groups before operation and at 48 hours after surgery(P>0.05).The concentra-tions of serum PRA,Ang-Ⅱ,ALD,cortisol,IL-6,IL-8 and TNF-αof FTS group were significantly different between the preoperative and different time points (P<0.05).The concentration of serum PRA,Ang-Ⅱ,ALD, cortisol,IL-6,IL-8 and TNF-αof FTS group were lower than that of control group at the same time point ( P<0.05).The operative time was(158.32 ±22.47)mins in FTS group and(161.32 ±22.37)mins in control group,respectively,and there were no significant statistical differences (P>0.05).The intraoperative blood loss in the FTS group(156.98 ±17.09)ml was not significantly less than that in the control group (158.57 ±16.92) ml(P=0.644).Hospitalization days were 8.37 ±1.89 and 10.37 ±2.05 in the FTS and the control group re-spectively ,with significant difference .The incidence of upper limb edema ,subcutaneous hydrops ,flap necrosis in FTS group were not less than control group .Conclusion Fast track surgery could attenuate stress and inflamma-tory response during ,and it is safe and effective in modified radical mastectomy .

Objective To compare the intensity of cognitive impairment and the level of pathological lesion in hippocampus induced by ischemia or chronic stress for a more valuable guidance in the treatment of post-stroke cognitive impairment(PSCI).Methods Forty male adult SD rats were divided medially into 4 groups:control,stress,ischemia and ischemia plus stress.Animals in 3 treatment groups were subjected respectively to an operation of modified selective middle cerebral artery occlusion or a procedure of continuous 3-week chronic unpredictable mild stress or a combined program of the two treatments.Morris water maze was employed to assess hippocampus-dependent learning and memory function and the brain-derived neurotrophic factor(BDNF)expression was detected by immunohistochemical staining in CA3 area and the mRNA amplification through semi-quantitative reverse transcription polymerase chain reaction(RT-PCR).Results Both chronic stressors and ischemia could significantly decrease the learning and memory function in rats like the escape latency in the performance of the Morris water maze test compared with the controL The stress group was related preferentially to a more severe deterioration in the learning function but not statistically in the memory loss as compared to ischemia group.The cognitive function decreased more markedly in rats when suffered the chronic unpredictable mild stresses plus ischemia,In comparison to control,ischemia significantly increased BDNF+ cells in hippocampal CA3 area (27.0 ±2.5 vs 20.1 ±2.1),while stress markedly reduced the expression of BDNF(15.2 ± 1.8 vs 20.1 ±2.1).Their combined effects still statistically led to a reduction in BDNF expression(8.2 ± 1.5,F =52.87,P ＜0.05).The same tendency was found in BDNF mRNA expression.Conclusions Stress may preferentially and powerfully influence hippocampus-dependent cognitive function compared with ischemia and the combination of focal ischemia and stress leads to the most impairments in cognition and hippocampal BDNF expression.Data suggest that more attention should be given to the strategies to increase the resistance to psychosocial stressors and decrease the depressed symptoms for a full PSCI recovery.

OBJECTIVETo investigate the effects of closed reduction and ulna intramedullary nail fixation for the treatment of fresh Monteggia fractures of Bado type I and II in children.

METHODSTwenty-three children patients with Monteggia fracture during July 2010 to September 2013 were treated by closed reduction and ulna intramedullary nail fixaion including 18 boys and 5 girls with an average age of 9.3 years old ranging from 6 to 13 years old. Among them,15 cases were Bado type I and 8 cases were Bado type II. There were 9 cases with radial nerve injury. The operation time,the recovery of nerve injury, the fracture healing and the function of elbow were observed and recorded.

Objective To evaluate the clinical significance of the detection of the Human Papilloma Virus (HPV) DNA typing in therapy of cervical diseases. Methods 780 cases have been studied. These cases which showed HPV-DNA positive and were diagnosed by biopsy as cervical cancer or cervical intraepithelial neoplasia( CIN Ⅰ-Ⅲ) were treated by operation or physical therapy. And 6 months and 12 months after the treatment,TCT and HPV DNA test were carried out. Results The prevalence of HPV-DNA types among the 780 cases descended from HPV 16 to 52,58,18,33 and 31. Detection rates of HPV-52 and 58 were highest among the patients with CIN Ⅰ. In patients with CIN Ⅱ,CIN Ⅲ,carcinoma in situ and invasive carcinoma,the positive rate of HPV-16 was obviously higher than other genotypes,and the difference was significant (P＜0. 01 ). 520 cases were followed-up after treatment,we found that HPV-DNA subsided within 3 months to 1 year in 432 cases. 88 cases still showed the HPV-DNA positive, among this group 48 cases were cytology diagnosed as normal or inflammation,but 14 cases were ASC-US,22 cases were LSIL and 4 cases were HSIL. Cytology abnormal cases were mere often detected in patients with persistent HPV-positive than in patients with HPV-negative. Conclusion Referring patients with cervical diseases the common HPV genotypes are 16,52,58,18,33 and 31. Especially HPV-16 are closely related with cervical cancer and high-level cervical intraepithelial neoplasis. HPV-DNA turn negative in most patients in 12 months after treatment. Persistent infection of HPV-DNA is related with the pathological changes persist.
