BACKGROUND: In previous studies on tissue-engineered adipose, the pore size of scaffolds is easily neglected. If the pore size was large, cells would flow away along the pore and could not maintain in the scaffold. If the pore size was small, cells would distribute on the surface of the scaffold, and could not enter the scaffold. Simultaneously, it would be not contribute to growth of new vessels. OBJECTIVE: To screen appropriate silk fibroin porous scaffolds to construct tissue-engineered adipose. METHODS: Under unchanged concentration of flbroin, six kinds of silk fibroin porous scaffolds in different aperture were prepared by changing freezing and drying temperature and time. Human umbilical cord mesenchymal stem cells (hUCMSCs) were harvested using attachment method. The potentiality of its osteogenic and adipogenic differentiation was detected by chemistry staining. The apertures of six kinds of silk fibroin porous scaffolds were measured by scanning electron microscope. The adhesion and proliferation of hUCMSCs on silk fibroin porous scaffolds in different aperture were observed. RESULTS AND CONCLUSION: The apertures of six silk fibroin porous scaffolds were (39.94±17.27), (53.51±16.18), (63.97±19.76), (71.08±18.07), (87.33±21.78), (121.97±44.10) μm, respectively. The strong ability of attachment of hUCMSCs appeared in the number two scaffold, and in other materials (number 1,3,4,5,6), there were not any cell in them except number one and three. Therefore, 50 μm might be a suitable aperture to construct tissue-engineered adipose with silk flbroin porous scaffolds using hUCMSCs.

Asteroid Hyalosis (AH) is a common clinical disease,which has been considered a benign disorder as it rarely impairs visual acuity.It was often discovered when the patient was treated for other eye diseases.The mechanism was unclear.Its characteristic B-ultrasound property makes the B-ultrasound a very helpful diagnostic technique.In the case of the patients with other fundus diseases associated with AH,optical coherence tomography (OCT) and fluorescein angiography (FA) may be used to reduce the interference from asteroid bodies,therefore improve the fundus visibility.Recent studies have shown that AH can incorporate with many other eye diseases.For example,in patients with cataracts,asteroid hyalosis can cause surface calcification of silicone plate intraocular lenses,which in most cases may lead to the need for explantation of the calcified intraocular lenses.The efficacy of pars plana vitrectomy (PPV),the removal of some,or all,of the eye`s vitreous humor for AH remains controversial.In this paper,we provide a review of the recent literature on AH disease: the etiology,diagnosis and treatment.We hope to thus improve the awareness and outcomes of AH disease.

Objective To compare the clinical therapeutic effects of continuous veno-venous hemofiltration (CVVH) and continuous veno-venous hemodiafiltration (CVVHDF) for treatment of patients with multiple organ dysfunction syndrome (MODS).Methods A prospective observation was conducted, seventy patients with MODS admitted to the Department of Critical Care Medicine of the Affiliated Hospital of Zunyi Medical College from September 2013 to December 2016 were enrolled, and they were divided into a CVVH group and a CVVHDF group according to different treatment, 35 cases in each group. In the CVVH group, the ultrafiltration fluid flow rate was set at 1800 mL/h, while in the CVVHDF group, the flow rate was set at 2000 mL/h for both substitution fluid and dialysate, and the blood flow of the two groups was 150-180 mL/min. The changes of creatinine (SCr), urea nitrogen (BUN), pH value, HCO3-, helper T cell (Th1, Th2) and Th1/Th2 ratio were compared between the two groups before and after treatment for 24, 48 and 72 hours.Results With the extension of time, SCr, BUN were reduced in both groups after treatment compared to those before treatment, 72 hoursafter treatment they reached the lowest value, and the degree of change in CVVHDF group was more significant than that in CVVH group [SCr (μmol/L): 150.62±32.09 vs. 180.41±30.52, BUN (mmol/L): 7.31±2.19 vs. 9.06±2.36. allP < 0.05], after treatment; the pH value, HCO3- level in the two groups had a tendency at first elevated and then lowered, 48 hours after treatment they reached the peak values, compared with those before treatment, the differences were statistically significant [CVVH group: the pH value 7.42±0.08 vs. 7.25±0.10, HCO3- (mmol/L) was 22.49±5.11 vs. 15.65±4.16; CVVHDF group: pH value 7.41±0.04 vs. 7.24±0.11, HCO3- (mmol/L) 23.24±4.78 vs. 15.65±4.16, allP < 0.05], 72 hours after treatment, they began reduced (CVVH group: pH value, HCO3- were 7.39±0.09, 22.35±4.91 respectively, CVVHDF group: pH value, HCO3- were 7.38±0.06, 23.13±4.61 respectively), but they were still significantly higher than those before treatment, and at each time point compared between the two groups, no statistical significant difference was seen (allP > 0.05). With the extension of therapeutic time, Th1, Th1/Th2 in two groups were gradually elevated after treatment, and 72 hours after treatment they reached the peak values; Th2 showed a trend of gradual decrease and after 72 hours of treatment it reached the lowest value, and the changes in CVVHDF group were more significant than those in CVVH group [Th1 (×10-2): 1.51±0.12 vs. 1.21±0.11, Th2 (×10-2): 1.64±0.65 vs. 1.70±0.18, Th1/Th2: 0.91±0.14 vs. 0.71±0.15, allP < 0.05].Conclusion Both CVVH and CVVHDF can effectively remove inflammatory mediators and metabolic products, adjust the balance of acid and base, regulate immune system in the body of patients with MODS, and the CVVHDF is more effective than CVVH.

Objective:[WT5BZ] The effects of exogenous vitamin C (VC) and glutathione (GSH) on ultraweak spontaneous luminescence of culturing pulmonary alveolus macrophages from rabbits were studiesd. [WT5FZ]Methods:[WT5BZ] In a special thermostat, which was passed through by airs with various concentrations of oxygen, the alveolar macrophages (AMs) were cultured in DMEM medium with VC or GSH, and the spontaneous luminescence of culturing AMs was examined by a luminometer. [WT5FZ]Results:[WT5BZ] when VC in medium was over 0.3 mmol/L, it could significantly enhance the oxidative luminescence of cells exposed to O 2 and cell death was resulted. However, when the cells were exposed to air without O 2 there was no significant effect. On the contrary,the lower concentration of VC (0.03 mmol/L) as well as GSH could reduce the spontaneous luminescence of cells exposed to a high concentration (99.1%) of O 2 in air. [WT5FZ]Conclusion:[WT5BZ] The results show that the spontaneous oxidation of culturing cells is an important reason for the ultraweak luminescence. High concentration of VC can promote cellular oxidative damage in vitro, but the exogenous GSH has a protective effect against oxidization in culturing cells.

Objective To provide clinical evidence for the optimal acupuncture time in acupuncture treatment of hearing disorder in kids with cerebral palsy.Method Ninety eligible patients were randomized into 3 groups, 30 in each group. Group A was treated for 30 min, group B for 45 min, and group C for 1 h. The hearing improvement was evaluated by using brain-stem auditory evoked potential (BAEP).Result The detection of BAEP showed that the latent and peak periods of wave I,Ⅲ, and V were significantly shortened in the 3 groups after intervention (P<0.01), suggesting that acupuncture can produce a marked efficacy in treating hearing disorder in cerebral palsy. The inter-group comparisons showed that the efficacy of group A was significantly higher than that of group B and C (P<0.05); there was no significant difference in comparing the efficacy between group B and C (P>0.05). It’s indicated that the optimal acupuncture time span should be 30 min.Conclusion With the same acupuncture skills, acupuncture for 30 min can produce a comparatively higher efficacy in treating infantile hearing disorder.
