Objective Comparing the influence on cardiac-pulmonary function of health and acute lung injury (ALI)dogs by proportional assist ventilation(PAV)and pressure support ventilation(PSV)modes.Methods Use intermittent positive pressure ventilation(IPPV)mode in health and ALI dogs,calculate elastance(Ers)and resistance(Rrs),then change to PAV,set the assist ratio 60%.Then change the mode into PSV,set the inspiratory pressure(IPAP)according to PAV,so that tidal volume(VT)and peak pressure(Ppeak)were the sanle as that of PSV respectively.Observe the changes of respiratory mechanics,blood gas analysis and hemodynamics during mechanical ventilation.Results For health dogs,compared with PAV,mean airway pressure(mPaw)and work of breath of ventilator(WOBv)of PSV was higher than those of PAV when VT were similar,the difference was remarkable;while the influence on hemodynamics was not different.For ALI dogs,compared with PAV,Ppeak,mPaw and pulmonary capillary wedge pressure(PCWP)of PSV was higher than those of PAV when VT were similar,the difference was remarkable.Conclusion For health and ALI dogs,compared with PSV,PAV has lower airway pressure and less influence on hemodynamies.

Objective To investigate the effect of Avastin (bevacizumab) combined with preoperative FOLFOX neoadjuvant chemotherapy on the prognosis of patients with locally advanced rectal cancer (LARC).MethodsA total of 80 cases of patients with LARC treated with total mesorectal excision (TME) in our hospital from January 2013 to January 2016 were randomly divided into the control group and the observation group, 40 cases in each group.The control group were treated with preoperative FOLFOX chemotherapy while the observation group were treated with bevacizumab injection, based on the treatment in the control group.21 days was a cycle of chemotherapy, and both groups were treated for at least 4 cycles.After 6 cycles of chemotherapy, operation was carried out, following TEM principle.The short-term and long-term prognosis, rate of R0 resection, the incidence of postoperative complications and side effects of chemotherapy were compared between the two groups.ResultsThere was no significant difference between the two groups in the good response rate of chemotherapy, the rate of R0 resection, the incidence of postoperative complications, the 1-year and 3-year survival rates and 1-year disease-free survival rate.The incidence rates of gastrointestinal reactions and bone marrow suppression in the observation group were 52.5% and 52.5%, respectively while in the control group were 25.0% and 20.0%, respectively (P<0.05), but there was no significant difference in the incidence rates of grade Ⅲ~Ⅳ gastrointestinal reaction and bone marrow suppression between the observation group and the control group (5.0% and 15.0% vs 2.5% and 5.0%).The 3-year disease-free survival rate of the observation group was higher than that of the control group (82.5% vs 60.0%) (P<0.05).ConclusionThe application of bevacizumab combined with preoperative FOLFOX chemotherapy in the treatment of LARC can improve the 3-year disease-free survival rate, without increasing postoperative adverse reactions and serious side effects of chemotherapy.

BACKGROUND: The cell growth, proliferation and differentiation caused by p38 mitogen-activated protein kinase (p38MAPK) might act as the common pathway in the onset and development of diabetic vascular complication.OBJECTIVE: To investigate the effect of atorvastatin on p38MAPK signal pathway and the influence of atorvastatin on cell proliferation and expression of transforming growth factor-β1 (TGF-β1) at transcriptional level in human glomerular mesangial cells (HGMCs) cultured with oxidative modification of low-density lipoprotein (ox-LDL).DESIGN: A randomized, parallelized, controlled and open trial.SETTING: Endocrinology Department, First Hospital Affiliated to China Medical University; Endocrinology Department,Respiratory Department, Urology Department, the General Hospital of Shenyang Military Area Command of Chinese PLA.MATERIALS: The experiment had been done in the laboratories for Pharmaceutical Department of China Medical University and Respiratory Department of Shenyang Military Area Command of Chinese PLA from May 2004 to May 2005. The sample was cut from renal cortex from the healthy segment of nephroectomy from a tumor patient (Provided by Xiang Jun, Urology Department, the General Hospital of Shenyang Military Area Command of Chinese PLA; Informed consent was obtained). OX-LDL was purchased from biochemistry institute of Peking Union Medical College (Batch No.20040711 ). ox-LDL was 5.3±1.0 nmol in 100 μg protein. Atorvastatin was purchased from Pfizer Pharmaceutical Co. Ltd (No. 45837088); p38MAPK monocloncal antibody was purchased from Santa Cruz.METHODS: ① 6.0-8.0 cm3 blocks of cortex were cut from renal cortex from the healthy segment of nephroectomy from a tumor patient, glomerular mesangial cells were isolated. When grew into 80% confluent monolayer, the cells were digested and performed passage. After the first two passages, the cells were pure based on morphology and characterized by DAB staining for Vimentin antigen and actin antigen was positive, whereas cytokeratin antigen was negative. Oil red "O" staining confirmed that ox-LDL was intaken by HGMCs. The 4-8th passages of cells were used to study. ②HGMCs were seeded into 96-well plates with 5×103 cells per well and grown in 200 μL culture medium. The study was divided into 5 groups (6 wells each group): 1.2, 6,12 mg/L atorvastatin group, ox-LDL group and blank control group. The cells were pre-incubated with atorvastatin for 30 minutes, then exposed to 80 mg/L ox-LDL. The cells in blank control group were untouched. After 24 hours, MTT was added. The absorbance of each sample at the wavelength of 492 nm was measured with immunosorbant assay system. The inhibitory rate of cell proliferation was calculated. ③1×106 to 3×106 cells were seeded into six 200 mL flasks. The trial was divided into 5 groups randomly:control group, 10, 40, 80 mg/L ox-LDL groups and atorvastatin group (12 mL/g). The cells in each group were pre-incubated for 30 minutes, then exposed to 80 mg/L ox-LDL for 24-routine culture. The expressions of TGF-β1mRNA of harvested cells were detected with semi-quantitative reverse transcription-polymerase chain reaction and p38MAPK signal pathway activation was detected by Western blot.MAIN OUTCOME MEASURES: ①Identification results of HGMCs. ② Proliferation of HGMCs. ③ TGF-β1 expression of HGMCs. ④p38MAPK signal pathway activation of HGMCs.RESULTS: ①When the cells were sub-cultured to the second generation, cell volume was big. Most of the cells were spindle-shaped, irregular stellate or branch-like, filled with microfilaments which paralleled axis. Cells overlapped in the intensive area. After DAB staining, cytoplastic actin and vimentin were positive and keratin was negative. Oil red "O"staining confirmed that ox-LDL was intaken by HGMCs with red granules in the cytoplasma, while control group did not.It was proved that the cells cultured for passage were HGMCs. ② As compared with control group, the inhibitory rate of cell proliferation in ox-LDL group was significantly decreased, but that in atorvastatin 1.2, 6 and 12 mg/L groups was significantly increased (0, -17.4%, 6.4%, 22.5%, 61.5%, respectively, P ＜ 0.05 or 0.01) on concentration-dependent manner. ③ As compared with control group, ox-LDL (10, 40, 80 mg/L) increased the expression of TGF-β1 and activation of p38MAPK in concentration-dependent manner, the effect of 80 mg/L ox-LDL group was the most significantly (P ＜ 0.01). Atorvastatin decreased the increment of TGF-β1 expression and the activation of p38MAPK pathway induced by ox-LDL significantly. There was significant difference when compared with 80 mg/L ox-LDL group (P ＜ 0.01).CONCLUSION: Atorvastatin can antagonize the activation of p38MAPK pathway, decrease the secretion of TGF-β1 and inhibit mesangial cell proliferation induced by ox-LDL, suggesting that it may exert beneficial effect in the prevention and treatment of diabetic nephropathy with dyslipidemia.

Objective To compare the effect of high volume continuous blood purification (CBP) with routine CBP on multiple organ dysfunction syndrome(MODS).Methods 38 patients with MODS were randomly divided into high volume CBP group( treatment group,18 cases) and routine CBP group (control group,20 cases).And they were respectively detected on mean arterial pressure(MAP),dosage of Dopamine,PaO2/FiO2,APACHE [ score,lactic acid,length of stay and mortality in ICU post-treatment 24h and 48h.Results Compared with control group,MAP and PaO2/FiO2 on treatment group were more higher( P ＜ 0.05 ),while dosage of Dopamine,APACHE Ⅱ score,lactic acid were significantly shorter than these of treatment group( P ＜ 0.05 ),and length of stay and mortality in ICU were significantly lower than those of treatmen group [ ( 8.54 ± 4.15 ) d vs ( 11.82 ± 5.76) d,P ＜ 0.05:22.2％ vs 35.0％,P ＜0.05 ].Conclusion High volume CBP could reduce the mortality in ICU compared with control group routine CBP.

ObjectiveTo examine the clinical utility of four methods in diagnosis of tuberculous meningitis.Methods A total of 60 patients with tuberculous meningitis were included as study group and another 70 patients with non-tuberculous intracranial infection as control group. Four methods, including conventional acid fast stain,Myobacterium tuberculous culture in BACTEC MGIT 960, real-time lfuorescent quantitative polymerase chain reaction (FQ-PCR) and modiifed acid fast stain, were used to assay the cerebrospinal lfuid specimens for diagnosis of tuberculous meningitis.ResultsThe positive rate was 11.7% (7/60), 6.7% (4/60), 48.3% (29/60), and 61.7% (37/60), respectively in the study group as tested by the four methods. There was signiifcant difference between the four methods in the positive rate (P< 0.05). Modiifed acid fast stain was more sensitive than the other 3 methods in identifying tuberculous meningitis (P< 0.05). This method also could identify the intracellularM. tuberculosis. All the 8 samples from the 4 patients who were positive for culture ofM. tuberculosis were positive in the modiifed acid fast stain.Conclusions The modiifed acid fast staining method is simple, fast, signiifcantly more senstive in detection of the acid fastM. tuberculosis in CSF, either extracellular or intracellular. It is worthwhile to further investigate its usefulness in early diagnosis of tuberculosis meningitis.
