Methods From June 2007 to June 2009, sixty-eight patients with stroke were randomly divided into treatment group and control group. Treatment group was treated with guiding strengthen occupational therapy and control group with trandional therapy. The MAL and the Bathel index were used to evaluate before treatment, after treatment and 3 months after treatment respectively. Results The MAL score and Bathel index were improved after treatment. The MAL score and Bathel index of the treatment group immediately and in 3 months after treatment increased greatly, and there were statistical significance (Plt;0.05). There was no difference in the MAL score and Bathel index in the control group before and after treatment. The MAL score and Bathel index of two groups were statistically significant after 3 months treatment (Plt;0.05). Conclusion Guiding intensified occupational therapy as a new kind of rehabilitation techniques, can improve the function of upper movement and daily life, and improve the quality life. It had high value of clinical applications.
The incidence and mortality of acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) are still very high, but stem cells show some promise for its treatment. Here we found that intratracheal administration of human umbilical cord-mesenchymal stem cells (UC-MSCs) significantly improved survival and attenuated the lung inflammation in lipopolysaccharide (LPS)-induced ALI mice. We also used the proteins-chip and bioinformatics to analyze interactions between UC-MSCs treatment and immune-response alternations of ALI mice. Then we demonstrated that UC-MSCs could inhibit the inflammatory response of mouse macrophage in ALI mice, as well as enhance its IL-10 expression. We provide data to support the concept that the therapeutic capacity of UC-MSCs for ALI was primarily through paracrine secretion, particularly of prostaglandin-E2 (PGE2). Furthermore, we showed that UC-MSCs might secrete a panel of factors including GM-CSF, IL-6 and IL-13 to ameliorate ALI. Our study suggested that UC-MSCs could protect LPS-induced ALI model by immune regulation and paracrine factors, indicating that UC-MSCs should be a promising strategy for ALI/ARDS.
Background Methylenetetrahydrofolate reductase gene (MTHFR C677T and A1298C) and methionine synthase gene (MS A2756G) polymorphisms have shown an association with male infertility risk in several ethnic populations. Although several studies have evaluated these associations in Chinese populations, their small sample sizes and inconsistent outcomes have prevented strong conclusions. Therefore, the present meta-analysis was performed with published studies to evaluate the associations of the three single nucleotide polymorphisms (SNPs) and male infertility in a Chinese population. Methods We conducted a search of PubMed, Embase, Web of Science, Chinese National Knowledge Infrastructure (CNKI), China biology medical literature (CBM), VIP, and Chinese literature (Wan Fang) databases up to May 31, 2016. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were used to assess the strength of associations with a random-effect model or a fixed-effect model based on the heterogeneity analysis results. Sensitivity analysis was used to confirm the reliability and stability of the meta-analysis. Results A total of nine studies, including 1,713 cases and 1,104 controls, were included in the metaanalysis. The pooled results indicated that the MTHFR C667T polymorphism was significantly associated with increased risk of male infertility in the Chinese population in the allele model (T vs. C: OR = 1.47, 95% CI = 1.32-1.63), the dominant model (TT + CT vs. CC: OR = 1.51, 95% CI = 1.30-1.77), the additive model (TT vs. CC: OR = 2.08, 95% CI = 1.68-2.58) and the recessive model (TT vs. CT+CC: OR = 1.58, 95% CI = 1.31-1.90), whereas the MTHFR A1298C and MS A2756G polymorphisms were not risk factors. There was no significant heterogeneity in any genotype contrasts among the studies. The sensitivity analysis indicated that the results of this meta-analysis were relatively stable. Conclusion This study suggests that the MTHFR C667T polymorphism may contribute to the genetic susceptibility to male infertility in the Chinese population, whereas MTHFR A1298C and MS A2756G polymorphisms may be unrelated to male infertility. Studies with larger sample sizes and representative population-based cases and well-matched controls are needed to validate our results.
Cancer-associated fibroblasts (CAFs) are one major type of component identified in the tumor microenvironment. Studies have focused on the genetic and epigenetic status of CAFs, since they are critical in tumor progression and differ phenotypically and functionally from normal fibroblasts. The present review summarizes the recent achievements in understanding the gene profiles of CAFs and pays special attention to their possible epigenetic alterations. A total of 7 possible genetic alterations and epigenetic changes in CAFs are discussed, including gene differential expression, karyotype analysis, gene copy number variation, loss of heterozygosis, allelic imbalance, microsatellite instability, post-transcriptional control and DNA methylation. These genetic and epigenetic characteristics are hypothesized to provide a deep understanding of CAFs and a perspective on their clinical significance.
Tracking of cells in biological systems is critically important for monitoring disease treatment, such as in stem cell therapy. This report prepared new types of biocompatible gadolinium hybrid iron oxide (GdIO) nanocomposites, which demonstrated high sensitivity for dual T-1- and T-2-weighted magnetic resonance imaging (MRI). The GdIO nanocomposites could efficiently label mesenchymal stem cells (MSCs) by incubation for 24 h at a safe dose, as they did not affect the cell viability, proliferation or differentiation capacity. There was high contrast enhancement in the GdIO-labeled stem cells for dual T-1- and T-2-weighted MR imaging. In addition, the GdIO nanocomposites were injected into adult mouse lateral ventricles, where cells could be labeled to monitor their biological behaviors by MRI. These GdIO nanocomposites with dual-imaging functions are a good platform for cell labeling and other diagnostic applications.
Mandibular prognathism (MP) is considered to be a cranial-facial disorder resulting from the interaction between genes and environment. Recent studies have demonstrated that susceptible chromosomal regions and candidate genes may be responsible for MP. In this study, the authors present current views on the effect of genetic components in nonsystematic mandibular prognathism, in order to clarify the genetic etiology of MP. Data source were Electronic databases, manual searching, and reference lists checking, up to April 2016. Study selection, level of evidence assessment, and data extraction were done by 2 individuals in duplicate. Ninety-one studies were retrieved in initial electronic and manual search, and based on the established inclusion and exclusion criteria, 15 were selected for the review. In result, loci 1p36, 1q32.2, 1p22.3, 4p16.1, 6q25, 19p13, 14q24.3, 14q31.1, and 14q31.2 were thought to harbor genes that confer susceptibility to MP. Genes Matrilin-1, ADAMTS1, COL2A1, and EPB41 seemed to be strongly associated with MP while gene of growth hormone receptor was in dispute. Genetic components appeared to be associated with MP. However, in view of the variety of populations and results in related publications, further studies are necessary to clarify the genetic etiology of MP.
Diabetic retinopathy (DR) is a serious complication of diabetes mellitus that not only impairs vision and quality of life but has also emerged as a leading cause of blindness in working-age individuals. Long non-coding RNA metastasis-associated lung adenocarcinoma transcript 1 (LncMALAT1) is a non-coding RNA molecule that regulates gene expression and has been implicated in the pathogenesis and progression of DR. It exerts its effects through the modulation of various pathological processes, including inflammation, oxidative stress, angiogenesis, and apoptosis. Notably, alterations in the expression levels of LncMALAT1 may serve as potential biomarkers for the early diagnosis of DR. Furthermore, interventions targeting LncMALAT1, employing antioxidants, anti-angiogenic agents, traditional Chinese medicine, and gene therapy, present promising avenues for its potential development as an effective therapeutic target for DR.
Here, the authors present a thermo-responsive shape memory polymer (SMP) foam that can be programmed to control the preosteoblast behavior by changing porous architecture during cell cultivation. The preosteoblast cells are seeded on the SMP foams with temporarily compressed pore structure. Results show that cells preferentially align along the pore length direction. After the pore recovery at 37 degrees C, cells remain attached and viable but change their topography in a tangential direction along the pore edge. This work indicates the shape-memory actuated porous structure in SMP foam can control the cell behavior. This may provide an effective method for studying cell responses to dynamic environment and facilitate the healthy and optimal development of tissue engineering.
A series of novel polycyclic spiro-fused carbocyclicoxindoles were synthesized and investigated for their in vitro antiproliferative activities against nine human cancer cell lines. Five compounds (10i, 101, 10n, 10p, and 10r) demonstrated anticancer activities against A2780s cells with IC50 values of less than 30 mu M. In particular, compound 10i showed anticancer activities against seven cancer cell lines and stronger activities than cisplatin in A2780s, A2780T, L126, and HCT116 cells. Further studies illustrated that compound 101 arrested cell cycle in G1 phase and induced apoptosis of HCT116 cells. This compound also effectively increased the protein levels of cleaved caspase-3, p53, and MDM2. Molecular docking results revealed that compound 101 could bind well to the p53-binding site on MDM2, indicating that it might work by blocking the MDM2-p53 interactions.

Objective To investigate the clinical features of non-gastrointestinal mucosa-associated lymphoid tissue ( MALT) lymphoma.Methods Forty-eight pathologically proved cases of nongastrointestinal MALT lymphoma, admitted into Peking Union Medical College Hospital fromJanuary 2000 to July 2011, were retrospectively analyzed.Results There were 32 females and 16 males. The median age at diagnosis was 55. 4 years old ( range, 21-76 years) . The most commonly affected sites were lung, salivary glands, thyroid and ocular adnexa. In5 cases, the lymphoma presented at multiple mucosal sites. 27 patients were asymptomatic while 13 had non-specific symptoms. Blood test showed mild or moderate anemia in 8 cases, elevated erythrocyte sedimentation rate in 19 cases, and elevated lactate dehydrogenase in 6 patients.Imaging examinations revealed enlarged lymph nodes in 20 patients. 6 patients had a history of Sjoren’s syndrome, in whom3 cases were salivary gland diseases. In the patients with lung involvement, pathological diagnosis was obtained by bronchial biopsies in 3 cases, by CT-guided percutaneous lung biopsies in 11 cases, and by surgical biopsies in 9 cases. While in the patients without lung involvement, pathological diagnosis was obtained all by surgical biopsies. Of the 23 patients with lung involvement, 1 remain untreated,while 22 received various combinations of treatment ( surgery alone in 3 patients, surgery plus chemotherapy in 6 patients, and chemotherapy alone in 13 patients) . Of the 25 patients without lung involvement, 11 patients received surgery alone, 10 patients received surgery plus chemotherapy, 3 patients received chemotherapy alone, and 1 patient received surgery plus chemotherapy and radiotherapy. 46 patients remained alive during the median follow-up of 46. 7 months ( range, 4-133 months) . While 1 patient with lung involvement died from unknown causes, another 1 patient with lung involvement died from lung infection. Conclusions Non-gastrointestinal MALT lymphoma tends to occur in old-aged females, and commonly occurs in lung, salivary gland and thyroid sites. Most patients are asymptomatic or have only nonspecific symptoms. CT-guided percutaneous lung biopsies and surgical biopsies are helpful to the diagnosis.Prognosis for this lymphoma tends to be indolent.
