Objective To explore the clinical effect of early cognitive rehabilitation on cognitive,physical function and quality of life in the patients transferred from intensive care unit (ICU).Methods A total of 120 cases of patients who were transferred from ICU to general wards was randomly divided into the control group and the observation group with 60 cases in each group.The control group was given symptomatic treatment according to their original disease,without cognitive intervention.On the basis of the control group,the observation group was treated with cognitive rehabilitation training,2 times / week,2 h/ times,12 weeks of treatment.The cognitive function,physical function and quality of life of two groups were compared with the memory and executive screening scale (MES),the daily activity scale (ADL),and the concise Health Survey (SF-36) before and after treatment.Results Compared to before treatment,after treatment,MES,SF-36 (in addition to bodily pain) and ADL scale project score in the observation group was significantly higher,SF-36 bodily pain scores decreased significantly,all the differences were statistically significant (P ＜ 0.05);Compared to the control group,after treatment,the MES,SF-36 (in addition to bodily pain) and ADL scale scores in the observation group of were significantly increased,the bodily pain score of SF-36 in the observation group compared with the control group decreased significantly,all the differences were statistically significant (P ＜ 0.05).Conclusions Early cognitive rehabilitation can significantly improve the cognitive,physical function and quality of life in the patients transferred from ICU,and it is worthy of clinical reference.

Objective To find out the changes of the soft tissue profile in Guangdong women with Angle's I teeth uncovered by lips after extraction of 4 first bicuspid teeth and to evaluate its significance. Methods Fifteen cases of adult Guangdong women with Angle's I teeth uncovered by lips were enrolled in this retrospective study. The X-ray film of lateral cephalometry was used to analyze the soft tissue profile in pre- and post- corrective tooth extraction. The paired t-test was statistically applied for comparison between the changes of lip tissue in pre- and post- correction. Results The changes occurred obviously in the angles of nose vs. lip and upper vs. lower lips, angle Z, and the length, thickness, esthetical plane distance and convex distance of upper and lower lips, but not in the angles of face and facial convex, basic angle of upper vs. lower lips and chin thickness. Conclusilons The facial dislocation and figure of these women have been positively improved after extraction of 4 first bicuspid teeth in spite of the larger thickness of lips than before correction, the just partly shortened distance between lips and the upper and front teeth still exposed and uncovered by lips to some extent. Further improvement depends on functional exercise of lip muscles.

Objective: To investigate the effect of ginsenoside-rg1 (G-Rg1) on rat’s cardiomyocytes H9c2 with its mechanism of signal pathwayin vitro.
Methods: H9c2 cells were cultured and treated in different conditions by following groups:①Blank control group,②Hypoxia alone group, the cells were treated for (2, 6, 12, 24, 48) hr respectively,③G-Rg1 group, the cells were treated by G-Rg1 at (5, 10, 50) μmol/L respectively,④YC-1 group, which is the speciifc inhibitor of hypoxia inducible factor-1α (HIF-1α),⑤YC-1 + G-Rg1 group,⑥Wortmannin group, which is the speciifc inhibitor for protein kinase B (Akt) phosphorylation and⑦Wortmannin + G-Rg1 group. Each experiment was conducted with 5 replicates. The effects of G-Rg1, hypoxia and YC-1 on cell activity and injury were studied; intracellular mRNA expressions of HIF-1α, glucose transporter-1 (GLUT-1) and heme oxygenase-1 (HO-1) were examined by RT-PCR; protein expressions of HIF-1α, GLUT-1, HO-1, activating transcription factor-6 (ATF-6), CCAAT/enhancer binding protein homologous protein (CHOP) and Akt with its signal pathway factors were measured by Western blot analysis.
Results: The time of hypoxia was negatively related to cell activity (r=-0.8580,P<0.05) and positively related to LDH overlfow rate (r=0.9201,P<0.05). G-Rg1 (10μmol/L) group showed increased cell activity than Hypoxia alone (24 hr) group (87.8% vs 62.6 %,P<0.05), while decreased LDH overlfow (25.0% vs 74.8%,P<0.05), and up-regulated mRNA expressions of HIF-1α, GLUT-1 and HO-1, P<0.05. YC-1+ G-Rg1 group had decreased cell activity than G-Rg1 group (68.0% vs 87.8%,P<0.05), while increased LDH overlfow (56.4% vs 25.0%,P<0.05). Meanwhile, YC-1 clashed the effect of G-Rg1 on protein expressions of HIF-1α, GLUT-1, HO-1, ATF-6 and CHOP,P<0.05; wortmannin clashed the effect of G-Rg1 on protein expressions of HIF-1α, CHOP,P<0.05 and suppressed the two phosphorylation sites for Akt activation,P<0.05.
Conclusion: G-Rg1 may protect rat’s H9c2 cellsin vitro by activating expressions of HIF-1α with its downstream factors and inhibiting endoplasmic reticulum stress, which might be related to the effect of G-Rg1 on Akt activation.

In the present paper, in-situ preparation of silver nanoparticles have been conducted in 3D network structure of BC membrane through liquid phase chemical deoxidization method. The characterization of products was investigated using scanning electron microscopy (SEM), infrared spectroscopy (IR), energy dispersion spectrometry (SEM-EDS). The absorbing water capacity and preserving water capacity of substitutes and the antibacterial capacities of antibacterial agent-loaded artificial skin were tested. The results showed the silver nanoparticles were approximately spherical particles with an average diameter of 45nm, and were noted to have excellent sterilizing efficacy the efficiency of against Escherichia coli, yeast and Candida albicans.

The complex pathological mechanism of dry eye involves multiple pathways, such as immunity and inflammation, and requires an integral research program to control the whole picture. Various histological techniques can elucidate the complex physio-pathological state of organisms from a holistic and global perspective, thus providing more comprehensive biological information. Mass spectrometry can sensitively detect the changes of protein content in tear samples, providing convenience for proteomics research of dry eye. At present, proteomics has demonstrated its application in the identification of dry eye types, severity grading, and therapeutic effect evaluation. In addition, proteomics combined with metabolomics and microbiomics can more comprehensively explain the pathogenesis of dry eye. In the future, proteomics is expected to provide more powerful support for the precise diagnosis and treatment of dry eye, taking an advantage in targeted therapy.

Approximately 140 million people worldwide are homozygous carriers of APOE4 (ε4), a strong genetic risk factor for late onset familial and sporadic Alzheimer's disease (AD), 91% of whom will develop AD at earlier age than heterozygous carriers and noncarriers. Susceptibility to AD could be reduced by targeted editing of APOE4, but a technical basis for controlling the off-target effects of base editors is necessary to develop low-risk personalized gene therapies. Here, we first screened eight cytosine base editor variants at four injection stages (from 1- to 8-cell stage), and found that FNLS-YE1 variant in 8-cell embryos achieved the comparable base conversion rate (up to 100%) with the lowest bystander effects. In particular, 80% of AD-susceptible ε4 allele copies were converted to the AD-neutral ε3 allele in human ε4-carrying embryos. Stringent control measures combined with targeted deep sequencing, whole genome sequencing, and RNA sequencing showed no DNA or RNA off-target events in FNLS-YE1-treated human embryos or their derived stem cells. Furthermore, base editing with FNLS-YE1 showed no effects on embryo development to the blastocyst stage. Finally, we also demonstrated FNLS-YE1 could introduce known protective variants in human embryos to potentially reduce human susceptivity to systemic lupus erythematosus and familial hypercholesterolemia. Our study therefore suggests that base editing with FNLS-YE1 can efficiently and safely introduce known preventive variants in 8-cell human embryos, a potential approach for reducing human susceptibility to AD or other genetic diseases.
