Objective To analyze the characteristics of bone marrow metastasis in large intestine carcinomas.Method [WT5”BZ]The systematic bone radionuclide images and clinical feature of pathology in 423 postoperative patients with colorectal carcinomas were analyzed retrospectively.Results Bone marrow metastases was confirmed in 191 cases accounting for 5 5% (191/3 454) of the patients admitted during the same period. 7 5% (146/ 1 934 ) of the rectal cancer cases had bone metastasis, which was significantly higher than that of 2 9%(45/1 520) in colon cancer (? 2=34 3, P 0 05). 108 cases had local metastasis, while 83 cases had systematic multiple metastases.Conclusions Bone marrow metastasis of large intestine carcinoma occurred most often secondary to liver and lung metastases. The bone metastasis in rectal carcinoma is more often than colonic carcinoma.

Objective To investigate the effect of SABP, a water-soluble component of Salvia miltiorrhiza, on the growth of orthotopic transplantation of H22 liver cancer and the immune microenvironment of liver cancer. Methods We established a mouse model of orthotopic transplantation of H22 cell liver cancer in BALB/c mice. ELISA was used to detect the expression of PD-L1, TGF-β, IL-1β, IL-10, IL-4, IFN-γ, IL-18, IL-7, IL-2, CCL-2 and CCL-21 in the liver. We counted the organ indexes of liver, spleen and kidney. Results SABP inhibited the growth of orthotopic transplantation tumors of H22 cell liver cancer, and increased the expression levels of PD-L1, TGF-β, IL-1β and IL-10 in the microenvironment of liver cancer, as well as the liver, spleen and kidney coefficients. Conclusion SABP could inhibit the growth of orthotopic transplantation tumors of H22 cell liver cancer and promote the expression of PD-L1, TGF-β, IL-1β and IL-10 in the microenvironment of liver cancer.

Objective:
To evaluate the results of catheter ablation of ventricular tachycardia (VT) via direct ventricle puncture access in patients without traditional approach.
Methods:
Two idiopathic left fasicular VT patients with mechanical aortic and mitrial valve repalcement and 1 patient with right ventricular originated VT post mechanical tricuspid valve repalcement from March 2010 to July 2012 in Fuwai hospital were enrolled in this study. For left fasicular VT patients, catheter ablation was performed using transapical left ventricular access via minithoracotomy. For the patient with right ventricular originated VT, catheter ablation was performed via percutaneous right ventricle puncture at xiphoid. Abaltion was guided under EnSite NavX mapping system. The feasibility of VT ablation via direct ventricle puncture access and long-term VT recurrence were investigated.
Results:
Catheter ablation was successful in all patients, and all clinical VTs were eliminated. The procedure time was 53, 62 and 74 minutes respectively with radiation time 11, 16 and 20 minutes. The ablation time was 130, 170 and 240 seconds individually. No procedure related complication occurred. After a follow-up time of 76, 55 and 82 months respectively, no VT recurrence was found in patients with left fasicular VT. New-onset VT with different morphology with previous VT was recorded in the patient with right ventricular originated VT, subcutaneous implantable defibrillator was implanted finally in this patient.
Conclusions
For patients with endocardial origined ventricular arrhythmias which could not be ablated via traditional approaches, direct ventricle puncture access with hybrid techniques provides a new approach foreliminating VTs in these patients.

OBJECTIVETo investigate the effects of secondary dust exposure after whole-lung lavage (WLL) on the clinical symptoms, arterial blood gas parameters, and pulmonary function in subjects with pneumoconiosis and patients with stage I coal workers' pneumoconiosis (CWP).
METHODSThe subjects with pneumoconiosis and patients with stage I CWP who underwent WLL in our hospital during the study period were selected. All patients were divided into postoperative dust exposure group (n = 86) and lavage control group (n = 86) according to whether they were exposed to dust after conventional operation. In addition, their workmates with similar age, history of dust exposure, and type of dust exposure were selected as non-lavage control group (n = 86). Follow-up was performed before and at one month and one year after WLL to evaluate clinical symptoms, arterial blood gas parameters, and pulmonary function.
RESULTSOne month after operation, the clinical scores of the postoperative dust-exposure group and lavage control group were significantly reduced compared with their preoperative scores and the clinical score of the non-lavage control group (P < 0.01). One year after operation, the clinical scores of the postoperative dust-exposure group and lavage control group were significantly reduced compared with their preoperative scores and the clinical score of the non?lavage control group (P < 0.01), and the lavage control group had a significantly lower clinical score than the postoperative dust exposure group (P < 0.01). One month after operation, the arterial partial pressure of oxygen (PaO2) of the postoperative dust-exposure group and lavage control group were significantly higher than their preoperative values and the arterial PaO2 of the non-lavage control group (P < 0.01). One year after operation, the lavage control group had significantly higher arterial PaO2 than the postoperative dust exposure group and the arterial PaO2 of the non-lavage control group was significantly lower than its preoperative value and the arterial PaO2 of the postoperative dust exposure group and lavage control group (P < 0.05 or P < 0.01); the postoperative dust exposure group showed a significant decrease in arterial PaO2 (P < 0.01), while the lavage control group showed a significant increase in arterial PaO2 (P < 0.01). The partial pressure of carbon dioxide showed no significant differences between the three groups before and at one month and one year after operation (P > 0.05).
CONCLUSIONDust exposure should be avoided after WLL to ensure the treatment outcome.
