Objective　To explore the correlation between the expression of p33/ING1 and the clinicopathological features in patients with colorectal cancer, and to understand the possible mechanism of p33/ING1 in the oncogenesis of colorectal neoplasms. Methods　All samples of normal mucosa and cancer tissues from 52 patients with colorectal cancer were detected for their expression levels of p33/ING1 by RT-PCR. Results　A significant decrease in p33/ING1 mRNA expression was found in 30 out of 52(57.7%) colorectal cancer tissues. The results also showed that repression of p33/ING1 expression markedly related to both the Duke's stage and metastasis. Conclusion　Down-regulation of p33/ING1 may play an important role in the oncogenesis and development of colorectal carcinoma.

Objective To explore the association of IL-10-592A/C polymorphism with the susceptibility to respiratory syncytial virus(RSV) bronchiolitis and disease severity,and to explore the impact of IL10-592A/C polymorphism upon total serum IL-10 levels in children with RSV bronchiolitis. Methods One hundred children (patients group) admitted to hospital with RSV bronchiolitis and 100 healthy children (control group) were recruited. PCR restriction length fragment polymorphism assay was used to detect the single nucleotide polymorphisms of IL-10-592A/C. Total serum IL-10 levels in patients group were assayed with ELISA. Results The genotype frequency of IL-10-592A/C were AA 44% ,AC 38% ,CC 18% in patients group ,and AA 41% ,AC 42% ,CC 17% in the control group,it showed no significant difference between two groups (χ2= 0. 33, P > 0. 05) . The frequency of each allele were A 63%, C 37 % in patient group, and A 64% ,C 36% in the control group,there was no significant difference in allele frequency between two groups (χ2=0. 43 ,P >0. 05) . There was no significant difference in total serum IL-10 levels between different genotype of IL-10-592A/C (F = 0. 87, P > 0. 05) . The differences in genotype frequency of IL-10-592A/C were not significant between mild and moderate to severe cases (χ2= 2. 67, P > 0. 05) . Conclusion IL-10-592A/C gene polymorphisms do not correlated with RSV bronchiolitis.

Objective To alleviate the side effects of glucocorticoid, we established a new procedure - intra - renal adipose capsule injection therapy to treat chronic glomerulonephritis. Methylprednisolone was injected into human renal adipose capsules of patients to treat primary glomerulonephritis. Methods 21 patients were diagnosed as primary glomerulonephritis by renal biopsies. Under the guide of sonograph,40mg methylprednisolone was injected into each renal adipose capsule of the patients twice a week, and each one of them was totally given ten times of the treatment. The urinary protein,plasma albumin, serum creatinine and blood pressure before and after the treatment were measured. Results The condition of most patients had been improved after the treatments. The excretion of urinary protein in 18 of 21 patients (85.1% ) had significantly been decreased (P

Mechanical ventilation is regarded as an effective means of replacing artificial ventilation during cardiopulmonary resuscitation (CPR), and has been widely used in the treatment of cardiac arrest (CA) patients. However, there are still some controversial issues remaining to be settled, such as the assessmentof the effectiveness of mechanical ventilation, the selection of the optimal oxygen concentration (FiO2), tidal volume (VT), respiratory frequency, and mode of ventilation during the CPR process. The pros and cons of positive pressure ventilation are also inconclusive. We reviewed and summarized the related research in recent years, and recommended that the intermittent positive pressure ventilation (IPPV) of volume controlled with small VT (6-7 mL/kg), low ventilation rates (10 times/min), and pure oxygen could be applied during the mechanical ventilation of CPR. The best mechanical ventilation strategy still needs further experimental researches to discover and explore.

ObjectiveTo study the expression of ING1 mRNA and its mutation status in human colorectal cancer. MethodsSamples of normal mucosa and cancer tissues from 52 patients with colorectal cancer were detected for their expression of ING1mRNA with RT PCR, and screened for its mutation with PCR SSCP. The expression of p53 protein was detected with immunohistochemical staining.ResultsThe impaired expression of ING1mRNA in colorectal cancer was associated with an advanced Dukes′ stage and metastasis of lymph nodes ( P ≤ 0 01). The expression of ING1mRNA positively correlated to that of p53 protein ( P ≤0 01). And a infrequent mutation of ING1 was also observed. Conclusion Our results suggest that ING1 contributes to the tumorigenesis and progression of colorectal cancer through down regulating its expression rather than through mutation.

ObjectiveTo study the efficacy of transcatheter arterial chemoembolization (TACE) combined with surgical resection in the treatment of ruptured hepatocellular carcinoma (HCC).MethodsThe clinical data of 26 patients who presented with ruptured HCC to our hospital from January 2008 to December 2011 were retrospectively studied. These patients received TACE (n=19),surgical resection (n=7),and surgical resection after TACE (n=8).ResultsShock in the 19 patients who received TACE was promptly corrected and the vital signs were stabilized.On subsequent CT,the tumors shrunk in size.Salvage liver resection was carried out in 8 patients 1 month after TACE.After treatment,AFP decreased or became normalized,thus the treatment results were good. A one-stage liver resection was carried out in 7 patients. One patient died after operation and peritoneal metastases occurred in 4 patients. Conclusions TACE stopped bleeding from ruptured HCC efficaciously,reduced the need for open exploration,and improved the rate of resection of HCC.TACE combined with surgical resection significantly lowered the rate of abdominal tumor metastases.
