Advanced schistosomiasis,encompassing a wide range of pathologic entities and multi-complications,poses a se-rious threat on the patients'health. Through comprehensive analysis and evaluation on related aspects regarding clinical classifi-cation,main methods of auxiliary examination and treatment(including types of surgical procedure)of advanced schistosomia-sis,we think that the individual based multidisciplinary comprehensive treatment according to varying conditions of patients is the most optimal treatment mode of advanced schistosomiasis. It is further proposed that multidisciplinary collaborative diagnosis and treatment system should be undoubtedly established,multidisciplinary case discussions be regularly organized,and treat-ment expert teams be stably formed,in order to significantly improve the level of diagnosis and treatment of advanced schistoso-miasis,so as to reduce the misdiagnosis and improve the therapeutic effect in advanced schistosomiasis control.

Objective To explore the clinical application of adaptive support ventilation (ASV) in elderly patients with acute respiratory failure.Methods A total of 46 mechanically ventilated patients aged over 65 years with acute respiratory failure admitted from January 2013 to June 2015 were enrolled.Comparison between the ASV mode and synchronized intermittent mandatory ventilation (SIMV) mode was carried out in respects of the impacts of both modes on respiratory mechanics, hemodynamics, oxygen availability and comfort rate.Results Difference between ASV and SIMV in respiratory rate was [(20.84 ±4.04) vs.(24.50 ±4.60) cycles/min, t =4.04, P ＜0.05], in inspiratory resistance was [(13.24 ±4.76) vs.(16.54±5.25) cmH2O/ (L·s), t=3.16, P＜0.05], in mean airway pressure was [(13.58±2.58) vs.(16.63 ±1.57) mmHg, t =6.84, P＜0.05], in peak airway pressure was [(25.96 ± 3.69) vs.(27.87 ± 2.45) mmHg, t =2.92, P ＜ 0.05], and tidal volume was [(378.41 ± 85.61) vs.(341.52 ± 86.84) mL, t =2.05, P ＜ 0.05], and comfort rate of patients was increased in ASV mode.There were no statistically significant differences in arterial oxygen partial pressure, carbon dioxide partial pressure, lactate, heart rate, mean arterial pressure and central venous pressure between the two modes (PP ＞ 0.05).Conclusions Compared with the synchronized intermittent mandatory ventilation mode, the adaptive support ventilation mode can improve the respiratory mechanics and can increase the comfort rate in the elderly patients with mechanical ventilation.

Objective To study the brain functional activation under speech stimulation in presbycusis pa‐tients using blood oxygenation level dependent functional magnetic resonance imaging (BOLD - fMRI) .Methods Eighteen normal hearing young volunteers ,10 normal hearing elderly people and 10 presbycusis patients received fM ‐RI under auditory task .Experimental tasks included monosyllabic verbal stimulating at tone of 1 kHz and sound in‐tensity to 90 dB ± 3 dB(after ambient noise detector Smart Sensor AR844 measurement and calibration) randomly transmitted to left and right ear .Following block design ,each stimulus was repeated twice .The lateralization of brain activation analysis observed changes in hemispheric dominance cases (or ear advantage change) .We observed brain activation analysis and changes of hemispheric lateralization advantage (or ear advantages) .SPM5 software was used to deal with the original pictures in the off - line work station to get fictional maps ,volume and intensity of the acti‐vated brain regions of interest ,and calculate the laterality index (LI) .Results To young people ,regardless of left or right ear stimulation ,the contralateral (region of intrest ,ROI) activation volume and intensity significantly increased compared to ipsilateral ,appearing contralateral hemispheric dominance ,and laterality index were - 0 .58 (left ear stimulation) and 0 .37 (right ear stimulation) .Compared to young people ,elderly people with normal hearing and presbycusis contralateral hemisphere conduction advantage was significantly reduced under monaural stimulation ,and the laterality indexes were - 0 .24 ,0 .28 (the aged group) ,- 0 .18 ,0 .25 (presbycusis group) .Young people received the left and the right ear auditory task respectively ,and the ratio of the total volume of bilateral ROI activation was 1 :2 .06 ,appearing to the right ear advantage (left brain dominance) .While the aged and presbycusis group manifes‐ted as right ear advantage decreased (left ear advantage enhanced) ,whose the total volume ratio was 1 :1 .51 for the old normal subjects and 1 :1 .61 for the hearing impaired seniors .Conclusion Auditory verbal tasks activated brain regions in the superior temporal gyrus and middle temporal gyrus were most obvious .Aging may cause these brain regions to be activated weaker ,appearing to the trend of contralateral hemisphere .The aging and deafness lead to the cortical reorganization .This may be one of the reasons for the declined speech recognition .

Objective To investigate the correlation of serum interleukin-6 (IL-6) and C-reactive protien (CRP) lev?els with left atrial thrombus and severe spontaneous echocontrast (SEC) in patients with atrial fibrillation (AF). Methods A case-control study of patients with atrial fibrillation (n=76) was carried out. All patients were divided into control group (n=45) and study group (n=31) according to their conventional echocardiography performance. Serum IL-6 and CRP were exam?ined in both groups. Results The levels of serum IL-6 in patients with thrombus and severe SEC were (324.13±42.86) ng/L and (332.29±53.17) ng/L, respectivly which is higher than that in patient without thrombus or without severe SEC (108.75± 25.43) ng/L and (93.59 ± 27.82) ng/L respectively. In parallel, CRP levels in patients of thrombus and severe SEC were (66.97 ± 17.65) mg/L and (71.81 ± 20.19) mg/L respectively which is higher than that in patients without thrombus or without severe SEC (17.28±6.52) mg/L and (16.76±8.73) mg/L respectively. All differences were of statistically significant(P<0.05). Conclusion Increase of serum IL-6 and CRP as well as high systemic inflammatory state correlate with left atrial thombus and severe SEC in patients with AF.

Objective To prepare magnetic polybutylcyanoacrylate (PBCA) nanosphere loaded with aclacinomycin A (ACM) and investigate its anti carcinoma effect and toxicity. Methods Magnetic PBCA nanospheres loaded with ACM were prepared by interfacial polymerization method. Female BABL/c nude mice were injected with MKN 45 gastric carcinoma cell line mass subcutaneously near right forefoot to establish human gastric carcinoma model. The mice were divided into 5 groups with 6 mice in each group: ACM (8 mg/kg), nanosphere with low dosage of ACM(1.6 mg/kg), nanosphere with high dosage of ACM (8 mg/kg ), magnetic nanosphere without ACM and normal saline (NS). Magnets (2500 Gs) were embedded in the tumor mass of all the mice one day before the date of therapy. The agents were administered again the same as the first time after 5 days. Tumor weight was measured and assay of colony forming unit granulocyte and macrophage (CFU GM) was performed on semi solid culture. Results The drug content of the agent was 12.0% and the mean particle size was 210 nm. The tumor inhibition rates of ACM, nanosphere with low dosage of ACM, nanosphere with high dosage of ACM and carrier without ACM on human gastric carcinoma in nude mice were 22.63%, 30.66%, 52.55% and 10.22% respectively. The average tumor weight of targeted nanospheres group was much lower than that of the same dosage of non targeted ACM group( P

Objective To inVestigate the effect of emodin on hyPertroPhic scar fibroblasts ( HSFs ) and exPlore the underlying mechanism. Methods HSFs were treated by emodin at final concentrations of 0,20,40,and 80 μmol·L-1, resPectiVely,in the cultural media. Forty_eight hours later,the cells were subjected to MTS assay and flow cytometry assay with annexin V and ProPidium iodide as dyeing indicators. Whole cell lysates from the cells of eVery grouP were subjected to Western blotting to measure the Protein exPression leVels of ERK1∕2,Bcl_2,Mcl_1 and RIP1. Results The cell Viability of HSFs was inhibited by emodin in a dose dePendent manner. The mortality rate of HSFs treated with emodin for 48 h at the concentrations of 40 and 80 μmol·L-1 were 28. 6%and 68. 0%,resPectiVely,which was significantly higher than that of the control grouP ( P<0.01).Pretreatmentwith Z_VAD_FMK could Partially reduce the mortality caused by emodin (P<0.05).PhosPhorylation of ERK1∕2 and the exPression of RIP1 and Mcl_1 were inhibited by emodin. Conclusion Down regulation of ERK1∕2,RIP1 and Mcl_1 by emodin may account for the inhibited Proliferation and increased cell death of HSFs.

Objective To study the effect of muskmelon juice on immune function of aged mice induced by D-galactose. Method Fifty male Kunming mice were randomly divided into five groups:normal control,aged model and three muskmelon juice (quadruple-diluted,double-diluted and stock juice) groups. The mice in aged model and three muskmelon juice groups were injected subcutaneously with D-galactose at dose of 200 mg/kg?d ,and the normal control with the normal saline of equal volume. The mice in three muskmelon juice groups were treated by intragastric administration twice daily with quadruple-diluted solution,double-diluted solution and stock liquid of muskmelon juice respectively,and the mice in normal control and aged model group with distilled water. Four weeks later,spleen and thymus were weighted,and the immunoglobulim and complement in serum were estimated. Results The thymus index of mice in aged model groop was much lower as compared with normal control. After administration with muskmelon juice,the thymus index was increased and the difference between stock juice and aged model group was significant. As compared with normal control,the serum IgG,IgM,C3,C4 contents of aged model were significantly lowered,but those in muskmelon juice group was increased. The IgG,C3,C4 contents of double-diluted and stock juice group were significantly higher than those of aged model. The spleen index and serum IgA contents fluctuated with same tendency. Conclusion Muskmelon juice can relieve the regression of immune organs in aging process and improve the immune function,suggesting to be effective in anti-aging process.

Objective To study the radiation-protective effects produced by the estrogenic activities of genistein(Gen) for providing experimental basis to develop the food for radiation protection. Method After blocking estrogen receptor (ER) activities by Tamoxifen and Faslodex,the effects of Gen on peripheral leucocytes and lymphocyte counts,serum haemolysin and delayed type of hypersensitivity of the mice were examined after exposure to 4 Gy ? radiation. Results Gen was shown to inhibit the decrease of peripheral leucocytes and lymphocyte counts and the decreased immune response of the ?-irradiated mice. Faslodex (ER? blocker) + Gen eliminated the protective effect of Gen and still caused the similar effects in hematological response and immune response after irradiation. Tamoxifen (ER? blocker) did not have these effects. Conclusion Gen can enhance the immune function in irradiated mice through activation of estrogen receptor ? pathway.
