Objective To evaluate the validity and responsiveness of the Chinese version of the miniBalance Evaluation Systems Test(mini-BESTest).Methods A total of 208 stroke patients were evaluated by 2 professionals using both mini-BESTest and Berg balance scale (BBS).All data were analyzed using Pearson correlation,t-test and descriptive statistical analysis.Results Significant correlation was observed between each entry of the mini-BESTest and its domain,with correlation coefficients ranging from 0.78 to 0.93 (P ＜ 0.05).The scores of whole assessment and the three related domains were significantly correlated between mini-BESTest and BBS results,the correlation coefficients ranging from 0.68 to 0.87 (P ＜ 0.05).After 2 weeks of treatment,there was significant improvement in each domain and in the total assessment score (P ＜ 0.05).No floor or ceiling effects were observed in the total mini-BESTest scores,but there was a slight ceiling effect in the anticipatory and sensory orientation domains,and a slight floor effect in the reactive postural control domain.Conclusion The mini-BESTest has good validity and responsiveness,and can be applied to evaluate patients after stroke.

Objective To research the effects of somatic sense interactive game Kinect on balance and walking function in stroke patients.Methods 40 patients with stroke were divided into control group (n=20) and experimental group (n=20), who accepted conventional rehabilitation and additional somatic sense interactive game Kinect. They were evaluated with gait analysis, Berg Balance Scale, Holden Walking Function Rating Scale and Barthel Index before and after treatment. Results Both groups improved in all the indices after 4 weeks of treatment (P<0.001), and improved more in the experimental group than in the control group (P<0.05). Conclusion The somatic sense interactive game Kinect could further improve the balance and walking function of stroke patients.

Objective:To correlate N-terminal pro-B-type natriuretic peptide (NT-proBNP) and heart type fatty acid binding protein (H-FABP) levels with the prognosis of patients with heart failure.Methods:Forty-nine patients with severe heart failure who received treatment in Tongde Hospital from December 2017 to June 2019 were included in the observation group. Forty-nine healthy subjects who concurrently received health examination were included in the control group. The heart function of the 49 patients was graded by the New York Heat Association (NYHA) classification. The levels of NT-proBNP and H-FABP were measured in different NYHA grades of patients and the healthy controls. The value of NT-proBNP and H-FABP levels in the diagnosis of heart failure was investigated and NT-proBNP and H-FABP levels were correlated with prognosis of heart failure.Results:In the observation group, NT-proBNP and H-FABP levels were (341.52 ± 12.74) pg/mL and (69.01 ± 11.45) ng/mL, respectively, which were significantly higher than (189.60 ± 12.73) pg/mL and (37.25 ± 11.44) ng/mL, respectively, in the control group ( t = 59.047 and 13.735, both P < 0.001). In patients with NYHA III grade severe heart failure, NT-proBNP and H-FABP levels were (295.62 ± 42.38) pg/mL and (75.09 ± 19.15) ng/mL, respectively, which were significantly higher than (120.43 ± 21.69) pg/mL and (21.76 ± 5.22) ng/mL, respectively in patients with NYHA I grade severe heart failure, (203.51 ± 42.77) pg/mL and (44.92 ± 10.85) ng/mL in patients with NYHA Ⅱ grade severe heart failure ( F = 55.100, 46.040, both P < 0.001). NT-proBNP and H-FABP levels in patients with NYHA I grade severe heart failure were significantly lower than those in patients with NYHA Ⅱ grade severe heart failure ( t = 7.231, 8.130, both P < 0.001). The sensitivity and accuracy of detecting NT-proBNP and H-FABP levels alone in the diagnosis of heart failure (76.92%, 78.85%, 84.69%, 86.73%) were significantly lower than those of detecting NT-proBNP and H-FABP levels in combination (98.08%, 97.96%, χ2 = 75.760, 10.913, both P < 0.001). NT-proBNP and H-FABP levels were positively correlated with the prognosis of heart failure ( r = 0.362, 0.611, both P < 0.05). Conclusion:NT-proBNP and H-FABP levels are positively correlated with the prognosis of severe heart failure in older adult patients. Detecting NT-proBNP and H-FABP levels in combination can increase the sensitivity and accuracy in the diagnosis of severe heart failure.

Objective To study the property of the K+ channels in mouse bone marrow stromal cells. Method Single-channel recording of the K+ channel currents in primary cultured mouse bone marrow stromal cell (BMSC) was performed using patch-clamp technique. Result A K+ channel with conductance of 16.7±1.4 pS was identified and characterized. The channel currents showed no inactivation in 75 s. Within a certain voltage range, the open time constant (to2) and open probability increased with depolarization, while the closed time constant (tc2) decreased. Conclusion The voltage-dependent K+ channel resembling the delayed rectifier K+ channel in excitable cells may play a role in the signal transduction of BMSC.

Objective To explore the interaction between hepatitis B virus(HBV) X protein and cytochrome C oxidase Ⅲ (COXⅢ).Methods Mating experiment and in vitro binding assays were utilized tO verify the interaction between HBV X protein and COX Ⅲ in vivo and in vitro respectively in yeast cells.Coimmunoprecipitation was employed to demonstrated the binding between these tWOproteins in mammalian cells.Results In mating experiment,the resulting diploids containing both pAS2-1-X and pACT2-COX Ⅲ plasmids turned blue in the β-gal assay,the result of Western blot displayed a positive reactive strap which indicated X protein could interact directly with COX Ⅲ in vitro binding assays.Interaction between these two proteins in mammalian cells was further confirmed by coimmunoprecipitation,as a protein strap about 17 000 was detected in Western blot.Conclusions It is speculated the specific interaction may exist between HBV X protein and COX Ⅲ in both prokaryotie and mammalian cells.X protein may impair the mitochondrial respiration chain and energy metabolism through its association with COX Ⅲ.

OBJECTIVETo investigate the risk factors and preventative measures for neonatal pneumothorax.

METHODSRetrospective analysis was performed on the clinical data of 2286 neonates who were hospitalized in the neonatal intensive care unit between October 2010 and November 2011, and a case-control study was conducted to analyze the risk factors and preventative measures for neonatal pneumothorax.

RESULTSThe incidence of pneumothorax among the neonates was 1.57% (36/2286), and it was significantly higher in full-term infants than in preterm infants (23/1033 vs 13/1253, P=0.023). Logistic regression analysis indicated that cesarean section, neonatal respiratory distress syndrome (NRDS), wet lung, pneumonia and mechanical ventilation were the independent risk factors for neonatal pneumothorax (odds ratios=7.951, 6.090, 7.898, 6.272 and 4.389; P<0.05 for all). The higher the peak inspiratory pressure (PIP) during mechanical ventilation, the higher the incidence of neonatal pneumothorax (P<0.001). Pulmonary surfactant reduced the incidence of pneumothorax among neonates with NRDS (2.9% vs 10.1%; P=0.006).

CONCLUSIONSNeonatal pneumothorax occurs mostly in full-term infants. Cesarean section, NRDS, wet lung, pneumonia and mechanical ventilation are closely associated with neonatal pneumothorax. Strict management of indications for cesarean section, keeping PIP at a low level during mechanical ventilation, and use of pulmonary surfactant are helpful in preventing neonatal pneumothorax.

Structural modifications were performed with natural product of oleanolic acid to search for novel anticancer drugs. Ten oleanolic acid derivatives were designed and obtained by the reaction of oxidation, acylation or hydrolyzation, etc. The cytotoxic activity of derivatives was evaluated against HeLa, HepG2 and BGC-823 cells in vitro by MTT assay, gefitinib and etoposide used as a positive control. The results showed that compound 5a was particularly active to inhibit HepG2 cells growth, and anti-tumor activity of compound 7 on HeLa cells was significantly stronger than oleanolic acid. They are worthy to be studied further.

AIM: To compare the efficacy of intravitreal injection of ranibizumab plus low power 532 laser versus 532 laser alone for treating retinal vein occlusion(RVO)with macular edema complication.

METHODS: Retrospective study of 48 patients diagnosed RVO complicated with macular edema from June 2017 to March 2018. Group A of 31 eyes(31 patients)were treated with intravitreal injection of ranibizumab plus low power 532 laser(the power is about 2/3 of the power of group B, about 100-130mw), and group B of 17 eyes(17 patients)were treated with 532 laser(the power is 150-200mw)alone. The best corrected visual acuity(BCVA), foveal retinal thickness(CMT), FFA and fundus were observed both before and after treatment at timepoint of 1mo, 2mo and 3mo between the two groups.

RESULTS: In group A, BCVA was 0.84±0.02, 0.49±0.04, 0.29±0.04, 0.26±0.04 before and the 1, 2, 3mo after treatment. In group B, BCVA was 0.85±0.04, 0.58±0.01, 0.53±0.01, 0.53±0.02. The CMT value of group A before and after treatment was 527.5±17.59, 371±17.36, 298.5±32.87, 257.75±17.30μm, respectively. Group B was 535±16.36, 425±24.44, 420.25±17.70, 427.75±17.89μm. Intra-group comparison show statistical differences, group A had lower BCVA and CMT value than group B at the same time point(P<0.05). Inter-group comparison with pre-treatment, there was significant difference in BCVA between 1mo, 2mo and 3mo after treatment(P<0.05). The CMT and BCVA value from group A are the lowest.

CONCLUSION: Both methods are effective in treating RVO with macular edema, improving vision, alleviating ME, and effectively controlling the disease.However, combined treatment can significantly reduce macular edema, improve vision, and be more stable than laser treatment alone.
