A multi-channel central monitoring system based on B/S mode is designed. It is consistent of the central monitoring server software, the Internet Explorer in the client PC, and a physiological signal collector. The server software can accept two client's request of data transfer, and real-time monitor several patients through Internet. The client uses the B/S mode, and just need to install an ActiveX control. The only thing users should to do is opening the Intemet Explorer, from which the waveform and signals are shown and transferred. The system extends the central monitoring service from hospital to the community, and is benefit for patient's long-term observation and cutting fees. Additionally, it can be a new solution of network based health care devices.

Objective To investigate the relationship between the biological characteristics and the expres-sion of stromlysin (MMP-7) and microvessel density (MVD) in breast cancer tissue and the effect of MMP-7 on MVD of breast cancer. Methods 60 fresh samples were obtained from patients with breast cancer,and then the ex-pression of MMP-7 and vascular endothelial cell CD34 were studied by means of immunohistochemical assay (SP method). The relationship between MMP-7, MVD and age, tumor size, histological type, lymph node metastasis and expression of ER, PR, PCNA, p53 and CerbB2 was studied. The relationship between the biological characteristics and the expression of MMP-7 and MVD in breast cancer were evaluated. Results The positive expression rote of MMP-7 in the d>2 cm group,the group with lymph node metastasis,the group with positive expression of PCNA, p53 and C-erbB-2 (78.1%,74.2%,71.8%,67.6% and 72.2%)were all higher than that in the d≤2 cm group, the group without lymph node metastasis,the group without positive expression of PCNA,p53 and C-erbB-2(32.1%, 41.3%,38.1%,38.5% and 33.3%) (P<0.05). MVD was higher in the positive breast cancer tissue of the group of d>2 cm(34.61±6.97), the group with lymph node metastasis (34.37±7.50), PCNA ( 33.24±8.39), p53 (33.28±8.94), C-erbB-2 (33.55±8.57) than in the negative breast cancer tissue of the d≤2 cm group ( 28.60±9.82), the group without lymph node metastasis (27.48±8.66), PCNA (26.88±7.89), p53 (21.71± 7.59),C-erbB-2(27.42±27.69) (P<0.05). MVD(33.62±7.36)/ high power lens in the MMP-7 positive group was higher than that (27.86±9.45)/high power lens in the MMP-7 of negative group(P<0.05). The posi-tive expression of MMP-7 was correlated with MVD (r=0.380, P<0.05). Conclusion The high expression of MMP-7 and MVD is associated with the development and metastasis of breast cancer. MMP-7 could promote the mi-crovessel development in mammary cancer.

Objective To explore the effects of reoperation on treatment of recurrent pelvic endometriosis(RPEM).Methods The clinical data of 47 cases of RPEM reoperation in our hospital from April 2005 to October 2010 was investigated,and the efficacy was analyzed compared with the first operation data.Results The cases of painful nodules was significantly different between reoperation group and the first operation group(28 vs 14,x2 =8.436,P =0.004 ).There was significant difference on laparoscopic surgery cases between reoperation group and the first operation group (25 vs 40,x2 =7.259,P =0.007 ).The operation time in reoperation group was significantly longer than that in the first operation group( [ 106.4 ±41.0] min vs [ 78.4 ± 26.4 ] min,t=3.995,P ＜ 0.01 ),and the amout of intraoperative hemorrhage in reoperation group was more than that in the first operation group ( [ 143.2 ± 118.3 ] ml vs [ 70.6 ± 68.1 ] ml,t =3.660,P ＜ 0.01 ).However,there was no significant difference on symptoms,cyst location and clinical stage between these two groups(P ＞0.05).Conclusion Due to the pelvic adhesion would be dense and extensive in RPEM,it should be carefully dissected during reoperation.At the same time,the operator should pay attention to the anatomical location and try to restore the normal anatomy of the pelvic organs and physiological state,and try to reduce postoperative adhesions.Complete removal of the lesions is the key to improve the treatment effect and prevent recurrence and reoperation.

Objective To investigate the association of T help (Th) lymphocyte and heart rate variability (HRV) in congestive heart failure (CHF) patients. Methods Ninety-six patients with CHF and thirty healthy persons were enrolled in the study. Time-domain HRV analysis was performed based on 24 hour Holter Electrocardiogram (ECG) monitoring. Interferon-γ (IFN-γ) was used as markers for the differentiation of Th1 subsets and interleukin-10 (IL-10) for the Th2 subsets. IFN-γand IL-10 in CD4 + T lymphocytes were quantified by 3-color flow cytometry. Results The frequency of IL-10-Producing T Cells in the CHF group was significantly lower than those in the healthy control ( ( 16.4 ± 5.8 ) % vs. ( 26.8 ± 3.7 ) %, t = 9. 243, P ＜ 0. 001 ). The frequency of IFN-γ in the CHF group ( ( 18.4 ± 7.3 )% ) was significantly lower than that in the healthy controls ( (7.3 ±4.6) % ,t =7. 917, P ＜ 0. 001 ). The following index of HRV in the CHF groups were all significantly lower than those in the healthy controls: (98. 6 ± 21.3) ms vs. ( 145. 1 ± 42. 6) ms for SDNN, (83. 9 ± 22.4) ms vs.(136.5 ±39.6)ms for SDANN, (40.6 ± 14.5) ms vs. (55.8 ± 17.9) ms for SDNNI, (20. 7 ± 12.9) ms vs.(29.1 ± 12.6) ms for RMSSD, (5.6 ± 3.7 ) % vs. ( 11.8 ± 4.4) % for PNN50 ( Ps ＜ 0.05 ). In CHF patients, the frequency of IL-10 were positively associated with SDNN, SDANN, SDNNI, RMSSD and PNN50 ( r = 0. 49,0. 57,0. 58,0.47 and 0. 52 ,respectively,Ps ＜ 0.01 ). In the CHF patients, the frequency of IFN-γand IFN-γ/IL-10 ratio were negatively associated with SDNN ,SDANN ,SDNNI, RMSSD and PNN50 ( r = - 0. 49, - 0. 54, - 0. 57, - 0.52,- 0.53, - 0. 52, - 0.64, - 0.57, - 0. 58, - 0. 67, Ps ＜ 0. 01 ). Conclusions Autonomic nervous system is involved in the regulation of the balance of Th1/Th2 in patients with CHF. Sympathetic nerve system enhances the effect of Th1 ,whereas parasympathetic nervous system enhances the effect of Th2.
