ObjectiveTo explore the feasibility and efficacy of hyperbaric oxygen (HBO) therapy combined with mild hypothermi on severe craniocerebral injury (SCI).MethodsAll 80 SCI patients were randomly divided into therapeutic group (52 cases) and control group (28 cases). All patients received general synthesis treatment; while the hyperbaric oxygen combined with mild hypothermia treatment was added to the therapeutic group. Changes of Vm, Vs and PI of middle cerebral artery (MCA) in systolic stage were detected by transcranial-Doppler (TCD) before and after treatment. The plasma level of endothelin (ET) was also tested and prognosis of patients was analyzed.ResultsVm, Vs and PI of MCA in systolic stage improved obviously and ET reduced greatly in therapeutic group compared with those in the control group (P<0.01), and prognosis was also superior to control group.ConclusionHyperbaric oxygen combined with mild hypothermia can improve the consciousness state and prognosis of SCI patients as a result of the relaxation of the cerebral vascular spasm and the reduction of ET, which may contribute to the abatement of the cerebral ischemia and hypoxia.

OBJECTIVETo analyze the clinicopathologic factors related to recurrence and metastasis of stage II or III colon cancer after radical resection.

METHODSThe clinical and pathological data of 628 patients with stage II or III colon cancer after radical resection from Jan. 2005 to Dec. 2008 in our hospital were retrospectively reviewed and analyzed.

RESULTSThe overall recurrence and metastasis rate was 28.5% (179/628). The 5-year disease-free survival (DFS) rate was 70.3% and 5-year overall survival (OS) rate was 78.5%. Univariate analysis showed that age, smoking intensity, depth of tumor invasion, lymph node metastasis, TNM stage, gross classification, histological differentiation, blood vessel tumor embolus, tumor gross pathology, multiple primary tumors, preoperative and postoperative serum concentration of CEA and CA19-9, and the regimen of adjuvant chemotherapy were correlated to recurrence and metastasis of colon cancer after radical resection. Multivariate analysis showed that regional lymph node metastasis, TNM stage, the regimen of postoperative adjuvant chemotherapy, and preoperative serum concentration of CEA and CA19-9 were independent factors affecting the prognosis of colon cancer patients.

CONCLUSIONRegional lymph node metastasis, TNM stage, elevated preoperative serum concentration of CEA and CA19-9, the regimen of postoperative adjuvant chemotherapy with single fluorouracil type drug are independent risk factors of recurrence and metastasis in patients with stage II-III colon cancer after radical resection.

BACKGROUNDPalliative chemotherapy has been shown to have a survival benefit for patients with recurrent or metastatic gastric cancer. We conducted a Phase II trial to determine the efficacy and safety of S-1 plus oxaliplatin (SOX regimen) as first-line chemotherapy for patients with unresectable locally advanced or metastatic gastric cancer.

METHODSEligible patients had measurable lesions and no previous history of chemotherapy (except adjuvant chemotherapy). Oxaliplatin was administered intravenously at a dose of 130 mg/m(2) on day 1. S-1 was administered orally in doses of 80, 100, or 120 mg/d according to body surface areas of <1.25 m(2), 1.25-1.5 m(2), or >1.5 m(2) respectively; the total dose was divided into two daily doses on days 1-14. Treatments were repeated every 3 weeks until disease progression or intolerable toxicity occurred.

RESULTSForty-three patients were enrolled in the study. All were assessable for efficacy and adverse events. The objective response and disease control rates were 55.8% and 76.7% respectively. The median follow-up time was 16.5 months. The median progression-free survival time was 7 months (95% CI, 5.8-8.2 months) and the median overall survival time was 16.5 months (95% CI, 9.7-23.3 months). The one-year survival rate was 54.2%. Major adverse reactions were grade 3/4 neutropenia (9.3%) and thrombocytopenia (20.9%).

CONCLUSIONThe SOX regimen with oxaliplatin at a dose of 130 mg/m(2) was found to be effective and safe as a first-line chemotherapy in Chinese patients with advanced gastric cancer.

This study aims to investigate the characteristics of genomic variation of pandemic A/H1N1/2009 influenza virus isolated in Fujian Province, China. Complete genome sequence analysis was performed on 14 strains of pandemic A/H1N1/2009 influenza virus isolated from Fujian during 2009-2012. All virus strains were typical low-pathogenic influenza viruses, with resistance to amantadine and sensitivity to neuraminidase inhibitors. Eight genome fragments of all strains were closely related to those of A/California/07/2009 (H1N1) vaccine strain, with > or = 98.2% homology. Compared with the vaccine strain, the influenza strains from Fujian had relatively large variation, and variation was identified at 11 amino acid sites of the HA gene of A/Fujiangulou/SWL1155/2012 strain, including 4 sites (H138R, L161I, S185T, and S203T) involved inthree antigen determinants (Ca, Sa, and Sb). In conclusion, the influenza vaccine has a satisfactory protective effect on Fujian population, but the influenza strains from Fujian in 2012 has antigenic drift compared with the vaccine strain, more attention should therefore be paid to the surveillance of mutations of pandemic A/H1N1/2009 influenza virus.

OBJECTIVETo evaluate the effects of small interference RNA (siRNA) on epidermal growth factor-like domain 7 (egfl7) gene expression in human endothelial cell line HUVEC.

METHODSsiRNA targeting egfl7 (siRNA1, siRNA2, siRNA3 and siRNA4) was constructed through online design of Amnion company and transfected into human endothelial cell line HUVEC with lipofectamine. The nontransfected cells and cells treated with control siRNA were taken as controls. At 24, 48 and 72 hours post various interventions, cell viability was determined by MTS method as well as LDH and ATP releasing tests. egfl7 expressions at protein and mRNA levels were detected by Western blot and RT-PCR respectively.

RESULTSCell survival rate, LDH and ATP release were significantly reduced in siRNA treated cells compared to control cells (P < 0.05). Similarly, egfl7 expression at protein and mRNA levels was also significantly reduced in siRNA treated cells (P < 0.01), especially in siRNA1 treated cells.

CONCLUSIONsiRNA inhibited egfl7 gene expression and cell survival in HUVEC.

OBJECTIVETo detect the expression of miR-124 in colorectal carcinoma (CRC) cells and tissue specimens and analyze its association with the radiosensitivity of the cells.

METHODSThe expression of miR-124 in CRC cell lines and tissues were detected using qRT-PCR. The effect of miR-124 in modulating cell radiosensitivity was assessed in CRC cells with miRNA-124 overexpression and miRNA-124 knockdown, and bioinformatics prediction and dual luciferase reporter system were employed to identify the direct target of miR-124.

RESULTSs miR-124 expression was down-regulated in CRC cell lines and tissues. CRC cells over-expressing miR-124 showed an obviously enhanced radiosensitivity, whereas miR-124 knockdown resulted in a reduced radiosensitivity of the cells. Bioinformatics prediction and dual luciferase reporter system verified PRRX1 as a direct target of miR-124, which regulated the radiosensitivity of CRC cells by directly inhibiting PRRX1.

CONCLUSIONmiR-124 can enhance the radiosensitivity of CRC cells by directly targeting PRRX1, which provides a target for improving the therapeutic effect of radiotherapy of CRC.

BACKGROUNDFamitinib is a novel and potent multitargeting receptor tyrosine kinase inhibitor. The phase I clinical study showed that famitinib was well tolerated and had a broad anti-tumor spectrum. The purpose of this study was to examine the efficacy and safety of famitinib for the treatment of metastatic renal cell carcinoma (mRCC).

METHODSThe data of famitinib in treating patients with mRCC from the single-center phases I and II clinical trials were analyzed. Famitinib was administered orally at the dose of 13-30 mg once daily until tumor progression, occurrence of intolerable adverse reactions or withdrawal of the informed consent.

RESULTSA total of 24 patients with mRCC were treated including 17 patients at a dose of 25 mg once daily, 4 patients at a dose of 27 mg and 1 patient each at a dose of 13 mg, 20 mg and 30 mg, respectively. Twelve (50.0%) patients achieved partial response (PR) and 9 patients achieved stable disease (SD). Progressive disease was found in 3 (12.5%) patients. The disease control rate was 87.5%. The median follow-up time was 17.6 months; the median progression free survival (PFS) was 10.7 (95% CI 7.0-14.4) months; and the estimated median overall survival (OS) time was 33.0 (95% CI 8.7-57.3) months. The adverse drug reactions mainly included hypertension (54.1%), hand-foot skin reactions (45.8%), diarrhea (33.3%), mucositis (29.2%), neutropenia (45.8%), thrombocytopenia (29.2%), hyperlipidemia (41.7%) and proteinuria (41.7%). The incidence rate of grades 3 and 4 adverse events was low, mainly including hypertension 12.5%, hand-foot skin reactions 4.2%, neutropenia 4.2%, thrombocytopenia 4.2%, hyperlipidemia 4.2% and proteinuria 12.5%.

CONCLUSIONSFamitinib has significant anti-tumor activity in mRCC. The common adverse reactions are generally manageable.

PURPOSE: Lipoprotein-associated phospholipase A2 (Lp-PLA2) is an inflammatory enzyme expressed in atherosclerotic plaques. We investigated the association of circulating Lp-PLA2 with characteristics of vulnerable coronary atherosclerotic plaques. MATERIALS AND METHODS: We recruited 113 patients with either unstable angina (UA, n=59) and stable angina (SA, n=54) by coronary angiography. Thirty-six healthy subjects served as controls. Intravascular ultrasound (IVUS) was used to evaluate the characteristics of coronary atherosclerotic plaque, and serum Lp-PLA2 concentration was measured as well. RESULTS: Lp-PLA2 concentration was significantly higher in both UA and SA patients [(396+/-36) microg/L and (321+/-39) microg/L, respectively] compared with the controls [(127+/-49) microg/L, p<0.01], and higher in UA than SA group. IVUS findings showed that remodeling index (RI) (0.91+/-0.15 vs. 0.85+/-0.11, p=0.005) and eccentricity index (EI) (0.73+/-0.16 vs. 0.65+/-0.22, p=0.039) were larger in UA than in SA group, and fibrous caps were thicker in SA than UA group [(0.91+/-0.23) mm vs. (0.63+/-0.21) mm, p=0.032]. Moreover, Lp-PLA2 correlated positively with EI (r=0.439, p<0.01) and RI (r=0.592, p<0.05) in UA group. There was an inverse relationship between Lp-PLA2 and fibrous cap thickness in both UA (r=-0.587, p<0.001) and SA (r=-0.318, p<0.05) groups. The independent risk factors in UA group were Lp-PLA2 (OR=1.055, 95% CI: 1.03-1.08, p=0.013), LDL-cholesterol (OR=0.032, 95% CI: 0.00-0.05, p=0.041) and fibrous cap thickness (OR=0.008, 95% CI: 0.00-0.45, p=0.019). Lp-PLA2 was strongly associated with both EI and fibrous cap thickness in both groups. CONCLUSION: Serum level of Lp-PLA2 is associated with both eccentricity index and fibrous cap thickness in both UA and SA groups. Elevated levels of circulating Lp-PLA2 might to be a strong risk factor and more serious for unstable angina than stable angina.

Objective:To explore the possible mechanism of electroacupuncture to improve detrusor hyperreflex after suprasacral spinal cord injury. Methods:A total of 60 female Sprague-Dawley rats were included. According to the random number table, twelve were selected as the blank group, twelve as the sham operation group, and the remaining 36 were made neurogenic bladder models using modified T₁₀ spinal cord transection. After that, twelve of them were randomly selected as the model group and twelve were as the electroacupuncture group from the model rats that met the requirements. On the 19th day after modelling, Ciliao (BL32), Zhongji (RN3) and Sanyinjiao (SP6) were taken for electroacupuncture. After seven days of continuous treatment, urodynamic testing was performed, content of cyclic adenosine monophosphate (cAMP) and protein kinase A (PKA) in detrusor was determined by ELISA, and the level of phosphorylation of myosin light chain kinase (p-MLCK) of detrusor was determined by Western blotting. Results:Compared with the blank group and the sham operation group, the maximum bladder capacity and bladder compliance significantly reduced (P < 0.01), and the base pressure and leakage point pressure of bladder significantly increased (P < 0.01); the content of cAMP and PKA in detrusor reduced (P < 0.01), p-MLCK in detrusor reduced (P < 0.05) in the model group. Compared with the model group, the maximum bladder capacity and bladder compliance increased (P < 0.01), the base pressure of the bladder and the pressure at the leak point decreased (P < 0.05); the contents of cAMP and PKA protein in detrusor increased (P < 0.05), the p-MLCK in detrusor increased (P < 0.05) in the electroacupuncture group. Conclusion:Electroacupuncture at Ciliao, Zhongji and Sanyinjiao points could improve the bladder function of rats with detrusor hyperreflex after complete spinal cord injury, and its mechanism may be related to up-regulating the expression of cAMP and PKA, phosphorylating and inactivating p-MLCK, which promote relaxation of detrusor.
