Objective To investigate the serum level of C reactive protein(CRP) in the hypertension patients with heart function impairment.Methods 68 hypertension patients who had no,mild or severe heart function impairment were se- lected and accordingly divided into 3 groups,while 30 healthy subjects served as normal controls.The levels of HS-CRP and LVEF was measured.Results All the hypertension patients had a high CRP level than normal controls(P

Objective To evaluate effection of the myocardial protective in treatment of coenzyme complex to the VR patients .Methods Eighty patients who need to VR were divided into control group ( n=40) and coenzyme complex group ( n =40) with double -blind.The automatic recovery rate of heart beats after cardiac resuscitation , the changes of postoperative arrhythmia rate , postoperative serum CK-MB, cTnI in 12h in two groups were recorded .Results The automatic recovery rate of heart beats was higher in coenzyme complex group than that in control group , (85%vs 67%, P <0.05).The changes of postopera-tive arrhythmia rate (26%vs 38%), serum CK-MB, cTnI at clamp off of aorta, end of operation,6hour of postoperation and 12 hour of postoperation were lower in coenzyme complex group than those in control group respectively ( all P <0.05 ) .Conclusion Coenzyme complex shows positive protection of myocardial in the VR patients.

BACKGROUND:Total knee arthroplasty mainly used fixed platform, but more and more movable platform was selected year by year in the clinic. Rotary platform theoretical y can apparently improve the curative effects, but it has not been verified in the clinic.
OBJECTIVE:To summarize the design characteristics and clinical results of Gemini MKII (Link, Germany) rotary platform.
METHODS:From January 2004 to January 2009, 108 patients (119 knees) including 31 males and 77 females were treated with total knee arthroplasty by using Gemini MKII system. There were 97 unilateral cases and 11 bilateral cases at the first stage of replacement. Preoperative diagnosis:1 case of hemophilic arthritis, 1 case of venereal Charcot’s disease, 8 cases of post-traumatic arthritis, 11 cases of rheumatoid arthritis, and 87 cases of degenerative osteoarthritis. The prosthesis was fixed with bone cement. None received patel ar replacement. RESULTS AND CONCLUSION:None experienced infection, femoral condyle fracture or nerve and vascular damage. Except bilateral replacement, the average operation time of unilateral replacement was (56±13) minutes. Average postoperative hemoglobin decreased (25±5) g/L. After replacement, hemoglobin maintained over 100 g/L in 83 patients (86%), without blood transfusion. Knee joint score and function score recovered to (92.0±4.7) points and (90.3±6.8) points at half years after replacement, and became (94.4±3.2) points and (91.6±5.9) points during final fol ow-up, which was significantly improved as compared with that pre-replacement (P<0.01). No revision surgery should be done for lining prolapse or spin out, osteolysis and prosthesis loosening. These results indicated that the early and midterm results of Gemini MKII rotating-platform prosthesis were satisfactory, but the long-term results remain to be confirmed.

Background:Clinical and epidemiological studies revealed that estrogen replacement therapy was associated with a significant reduction in risk of colorectal cancer in postmenopausal women.In our previous studies,estrogen increased the expression of mismatch repair (MMR)gene MLH1 in colonic cancer cells,and re-expression of MLH1 in MLH-deficient colonic cancer cells significantly increased the estrogen-induced apoptosis.Aims:To investigate the signaling pathway implicated in the MLH1-mediated apoptosis in colonic cancer cells induced by estrogen and the roles of p53 and its related genes in this apoptotic pathway.Methods:Plasmid containing wild type human MLH1 (hMLH1)full length cDNA was transfected into MLH1-deficient human colonic cancer cell line HCT116.By using HCT116 cells transfected with empty plasmid as controls,the apoptotic DNA ladder was determined by electrophoresis and the expressions of p53 and other apoptosis-related proteins were assessed by Western blotting under the condition with or without estrogen stimulation. Results:17β-estradiol (E2 )at the concentration of 10 -8 mol/L induced significant apoptosis in HCT116 cells transfected with hMLH1.In HCT116 cells transfected with hMLH1 and stimulated with E2 (group D),the protein expressions of caspase-3,caspase-9,p53,Bax and cytoplasmic cytochrome C increased significantly when compared with HCT116 cells stimulated with E2 only (group B);expressions of the abovementioned proteins were also higher in group D than in group C (transfected with hMLH1 only).Conclusions:MMR gene MLH1 is involved in estrogen-induced apoptosis of human colonic cancer cell line HCT116 by activating p53 signaling and mitochondrial apoptotic pathway.

Objective To explore an optimal treatment and to study the prognosis related factors of breast cancer patients with local recurrence after mastectomy. Methods From 2002. 7 to 2005. 2, 477female patients with loco-regional recurrence of breast cancer treated in Tianjin Cancer Hospital were analyzed retrospectively. Results In 477 cases, recurrence within 1 year after mastectomy accounted for 26. 2% , recurrence within 2 years accounted for 61. 2%. There were 310 cases with metastasis after local recurrence was diagnosed, accounting for 65.0%. 5-year total survival rate after recurrence is 48.4%.Local control rates varied in subgroups with different recurrence site, clinical subtypes, radiotherapy fields,with or without radiotherapy, surgical resection or excisional biopsy ( P<0. 05 ). There was a statistical difference in distant metastasis rate and 5-year survival rate among subgroups which had different clinical stage of primary tumor, disease-free interval, clinical subtypes or treatment methods ( P<0. 05 ). Simplistic treatment option, late clinical stage of primary tumor and triple-negative breast cancer were the independent factors predicting poor prognosis for recurrent breast cancer ( P<0.05 ). Conclusions Multi-site recurrence and triple-negative breast cancer lead to a poor local control. Local expansion of radiotherapy combined with surgery improves the local control rate. Patients with late clinical stage of primary tumor,recurrence within 2 years, triple-negative breast cancer are likely to have distant metastasis when recurrence is diagnosed. Combined treatment program improves survival rate.
