Through scale-up cultivation of Eriobotrya japonica suspension cells using WAVE bioreactor, the cell growth and ursolic acid (UA) accumulation were studied. The comparison test was carried out in the flask and the reactor with cell dry weight (DW) and UA content as evaluation indexes. The culture medium, DW and UA content were compared in 1 L and 5 L working volumes of bioreactor. The orthogonal test with main actors of inoculation amount, speed and angle of rotation was developed to find the optimal combination, in 1 L working volume of bioreactor. DW of the cell growth and the UA content in bioreactor were higher than those of the shaker by 105.5% and 27.65% respectively. In bioreactor, the dynamic changes of elements in the fluid culture, the dry weight of the cell growth and the UA content in 1 L and 5 L working volumes were similar. Inoculation of 80 g, rotational speed of 26 r · min(-1), and angle of 6 ° was the optimal combination, and the cell biomass of 19.01 g · L(-1) and the UA content of 27.750 mg · g(-1) were achieved after 100 h cultivation in 1 L working volume of bioreactor. WAVE Bioreactor is more suitable than flasks for the E. japonica cell suspension culture, and culture parameters can be achieved from 1 L to 5 L amplification.

Objective To observe the effects of a rehabilitation robot and body weight supported treadmill training (BWSTT) on the walking ability of hemiplegic patients after stroke.Methods Sixty hemiplegic patients were divided randomly into treatment and control groups (n=30 in each).The treatment group received training assisted by a leg rehabilitation robot for 10-20 min once daily,6 days per week for 8 weeks in addition to conventional treatments and BWSTT.The control group was only given conventional treatments and BWSTT once daily for 8 weeks.Their lower extremity functions,balance and walking ability were assessed with a simplified Fugl-Meyer assessment (FMA) and using the Berg balance scale (BBS) and Functional Ambulation Categories (FACs).Results After training,both groups showed significant improvements in terms of FMA,BBS and FAC results.The treatment group showed significantly better improvements in lower extremity function,balance and walking ability compared with the control group.Conclusions The lower-limb rehabilitation robot and BWSTT could together improve balance and walking ability.

[ ABSTRACT] AIM:To investigate the effect of oxidized low-density lipoprotein ( ox-LDL) on autophagy in mac-rophages and the underlying molecular mechanisms.METHODS:RAW264.7 macrophages were pretreated with 2 mg/L anti-CD36 monoclonal antibody (anti-CD36 mAb), 5 μmol/L diphenyleneiodonium (DPI), 3 mmol/L 3-methyladenine (3-MA) or 1μmol/L rapamycin for 1 h and then treated with ox-LDL (100 mg/L) for 12 h.The viability of the cells was measured by MTT assay.The activities of lactic dehydrogenase ( LDH) in the medium and nicotinamide adenine dinucleoti-de phosphate ( NADPH) oxidase, superoxide dismutase ( SOD) in the cells as well as the levels of intracellular reactive ox-ygen species ( ROS) and malondialdehyde ( MDA) were determined to characterize the membrane integrity and the oxida-tive stress, respectively.The protein levels of beclin-1 and microtubule-associated protein 1 light chain 3-II ( LC3-II) , 2 important molecular markers of autophagy, were examined by Western blotting.RESULTS:ox-LDL induced autophagy in
RAW264.7 macrophages as assessed by upregulation of beclin-1 and LC3-II.Similar to 3-MA, an autophagy inhibitor, an-ti-CD36 mAb significantly inhibited the ox-LDL-induced upregulation of beclin-1 and LC3-II.Anti-CD36 mAb suppressed the ox-LDL-induced oxidative stress as revealed by decreased NADPH oxidase activation, ROS and MDA generation as well as increased SOD activity.Similar results were observed in the cells pretreated with DPI, a NADPH oxidase inhibitor.Mo-reover, DPI significantly inhibited the ox-LDL-induced upregulation of beclin-1 and LC3-II.Inaddition, the decrease in the cell viability and increase in LDH release induced by ox-LDL were promoted by 3-MA and blocked by rapamycin ( an auto-phagy inducer).CONCLUSION: ox-LDL induces autophagy in RAW264.7 macrophages, which may be involved in CD36-mediated ox-LDL uptake and subsequent activation of oxidative stress, and moderate activation of autophagy may pro-tect macrophages from ox-LDL-induced injury.

[Absract] Objective To investigate the imaging features of CT and MRI of echinococcosis, and improve the imaging knowledge of the disease. Methods Clinical and radiological findings of echinococcosis of ribs were retrospectively analyzed by reviewing the seventeen cases confirmed by clinical and pathological findings. All patients had CT scan, eight had X?ray plain film and five had MR examination, while 4 patients underwent additional contrast?enhanced CT examination. Results All lesions were unilateral. There were 33 ribs involved, and single involved rib was seen in 7 cases. On CT scans, 10 cases showed cystic, swelling and osteolytic bone destruction, and 7 cases showed moth?eaten osteolytic bone destruction. There were 13 cases of hydatid cyst, 3 cases of a single sac watery density shadow and 10 cases of polycystic separating wheels form. There were 4 cases of fractured ribs, 2 cases of the longitudinal fracture and 2 cases of the transverse fracture. On MRI, there was one case of rib medullary cavity expansion destruction. It was a single cyst with hypointensity on T1WI, hyperintensity on T2WI and hyperintensity on short time inversion recovery (STIR) images. There were one case of rib medullary cavity expansion destruction and 3 cases of hydatid erosion ribs cortex among 4 cases of polycystic type. Polycystic type echinococcosis appeared hypointensity on T1WI, hyperintensity on T2WI and hyperintensity on STIR images. Polycystic type had mother sac and ascus structure, and signal intensity of ascus was higher. STIR sequence showed more clearly polycystic structure. Conclusions CT and MRI can clearly show location of echinococcosis of ribs. There are the imaging features of cystic, swelling and osteolytic bone destruction or complicating cyst of polycystic type which can help the qualitative diagnosis of rib echinococcosis.

To analyse the relationship between tumor necrosis factor (TNF)-α and interleukin-6 with hyperuricemia in ethnic Uygur,Kazak,and Han in Xinjiang province.1 200 cases of Uygur,Han,and Kazak populations were randomly enrolled.Serum uric acid,triglyceride,total cholesterol,high density lipoprotein-cholesterol,low density lipoprotein-cholesterol,fasting plasma glucose,body weigh and height,waist circumference,and hip circumference were measured.Waist-to-hip ratio and body mass index were calculated,and TNF-α,interleukin-6 were determined.The differences between uric acid and inflammatory factors were statistically significant; The differences in TNF-α was statistically significant between high uric acid group and control group in Uygur and Han,and the differences in interleukin-6 was statistically significant between high uric acid group and control group in Uygur,Kazak,and Han(P＜0.01).TNF-α and interleukin-6 were positively correlated with serum uric acid in Uygur,but in Kazak only interleukin-6 was negatively correlated with serum uric acid,in Han only interleukin-6 was positively correlated with serum uric acid(P ＜ 0.01).Hyperuricemia was associated with inflammatory factors,TNF-α,interleukin-6,but there were ethnic differences among Uygur,Kazak,and Han,thus it may provide people of new ideas for prevention and treatment of hyperuricemia and other related metabolic disorders.

The heterogeneity of high-density lipoprotein-cholesterol (HDL-C) in hyperuricemia was analyzed in Uygur,Han,and Kazak ethnic groups in Xinjiang.A total of 2 396 subjects were surveyed.The HDL-C levels were significantly decreased in hyperuricemia group compared with control group in Han and Uygur,while the reverse occurred in Kazak.The serum uric acid (SUA) level in Kazak was the lowest.The SUA was negatively correlated with HDL C in Kazak (P ＜ 0.05).HDL-C was a recognized protective factor for cardiovascular disease.With the lowered SUA level in the Kazak group,HDL-C level was increased.When SUA level was higher than a certain level (such as the SUA-4),there existed a negative impact on cardiovascular disease

Objective To investigate the effect of pelvic intensive training on gait of stroke patients with hemiplegia. Methods 60 stroke patients with hemiplegia were divided into control group (n=30) and observation group (n=30). Both groups received routine rehabilitation training. The observation group received pelvic intensive training, twice a day, additionally.
