SLC7A11 negatively associates with mismatch repair gene expression and endows glioblastoma cells sensitive to radiation under low glucose conditions.

The cystine/glutamate antiporter xCT (SLC7A11) is frequently upregulated in many cancers, including glioblastoma (GBM). SLC7A11-mediated cystine taken up is reduced to cysteine, a precursor amino acid for glutathione synthesis and antioxidant cellular defense. However, little is known about the biological functions of SLC7A11 and its effect on therapeutic response in GBM. Here, we report that the expression of SLC7A11 is higher in GBM compared with normal brain tissue, but is negatively associated with tumor grades and positively impacts survival in the bioinformatic analysis of TCGA and CGGA database. Additionally, a negative association between SLC7A11 and mismatch repair (MMR) gene expression was identified by Pearson correlation analysis. In the GBM cells with glucose-limited culture conditions, overexpression of SLC7A11 significantly decreased MMR gene expression, including MLH1, MSH6, and EXO1. SLC7A11-overexpressed GBM cells demonstrated elevated double-strand break (DSB) levels and increased sensitivity to radiation treatment. Taken together, our work indicates that SLC7A11 might be a potential biomarker for predicting a better response to radiotherapy in GBM.

miR-26 suppresses renal cell cancer via down-regulating coronin-3.

Coronin-3 (coronin-1C), a homotrimer F-actin-binding protein, has been reported to be important for metastasis in several types of cancers such as lung cancer, gastric cancer, and breast cancer. Here, we present an investigation of the expression and function of coronin-3 in renal cell cancer for the first time. We also confirmed that miR-26 directly targets coronin-3 and down-regulates its expression by western blot assay and dual-luciferase reporter system. The results of MTT and colony formation assay showed that miR-26 suppressed cell proliferation. Wound healing and transwell assay revealed that miR-26 inhibited migration and invasion of renal cancer cell. Moreover, overexpression of coronin-3 could reverse the miR-26-induced inhibition in cell growth and metastasis. Thus, our study suggests that coronin-3 should serve as a potential therapeutic target in renal cell cancer and provide a candidate for miRNA therapy.

Proton-Conductive Cocrystals of Twin Isomers of Coordination Polymers in Situ Formed by Keggin Anions and Cu(II)-4,4'-Bis(hydroxymethyl)-2,2'-bipyridine Complex Moieties.

Cocrystals and isomers, two well-known unique concepts in supramolecular chemistry, are rarely put together until now. For the first time, we report three unprecedented and interesting cocrystals of twin isomers of coordination polymers (CPs) in situ formed by typical Keggin anions and Cu(II)-4,4'-bis(hydroxymethyl)-2,2'-bipyridine (Cu(II)-H2L) complex moieties. In cocrystals 1-3, the Cu(II)-H2L complex moieties are quadrisupported on Keggin-type anions through W(Mo)-Ot-Cu-Ot-W(Mo) (Ot is the terminal O atom) links in the crystal to form two twin ionic/neutral CPs with a fixed chemical stoichiometry. Cocrystals 1-2 contain ionic isomers as {[Cu1(H2L)(H2O)2]2[P1W12O40]} n n+/{[Cu2(HL)(H2O)2]2[P2W12O40]} n n- for 1 and {[Cu1(H2L)(H2O)2]2[P1Mo12O40]} n n+/{[Cu2(HL)(H2O)2]2[P2Mo12O40]} n n- for 2. Cocrystal 3 contains neutral isomers as {[Cu1(H2L)(H2O)2]2[Si1W12O40]} n and {[Cu2(H2L)(H2O)2]2[Si2W12O40]} n. Cooperation of conformation and hydrogen bond network isomerism of Cu(II)-H2L fragments and tetracoordinated mode isomerism of Keggin anion is perfectly embodied in twin isomers. Moreover, based on hydrogen-bonding interactions, twin isomers are alternately arranged in a 1:1 stoichiometric ratio to give a cocrystal. Complicated accumulation of three types of hydrogen-bonding assemblies in the same crystal may be the reason that they give conductivity values over 10-4 S·cm-1 at 100 °C under 98% relative humidity.

Plasmon resonances in a stacked pair of graphene ribbon arrays with a lateral displacement.

We find that a stacked pair of graphene ribbon arrays with a lateral displacement can excite plasmon waveguide mode in the gap between ribbons, as well as surface plasmon mode on graphene ribbon surface. When the resonance wavelengthes of plasmon waveguide mode and surface plasmon mode are close to each other, there is a strong electromagnetic interaction between the two modes, and then they contribute together to transmission dip. The plasmon waveguide mode resonance can be manipulated by the lateral displacement and longitudinal interval between arrays due to their influence on the manner and strength of electromagnetic coupling between two arrays. The findings expand our understanding of electromagnetic resonances in graphene-ribbon array structure and may affect further engineering of nanoplasmonic devices and metamaterials.

Causal effects of gut microbiota on the risk of erectile dysfunction: a Mendelian randomization study.

Erectile dysfunction ranks among the prevalent sexual disorders in men. Several studies have indicated a potential link between gut microbiota and erectile dysfunction. To validate this potential association, we were to screen statistical data from genome-wide association studies of gut microbiota and erectile dysfunction. p values of less than 1 × 10-5 were set as the threshold for screening instrumental variables that were strongly associated with gut microbiota. At the same time, in order to obtain more convincing findings, we further excluded instrumental variables with possible chain imbalance, instrumental variables with the presence of palindromes, instrumental variables with F-statistics less than 10, and instrumental variables associated with risk factors for erectile dysfunction. Five methods including inverse-variance weighted method, weighted median method, weighted mode, Mendelian randomization egger method and Mendelian randomization pleiotropy residual sum and outlier test were then used to analyse the 2591 instrumental variables obtained from the screening. We identified correlations between six gut microbiota and the risk of erectile dysfunction. The genus Ruminococcaceae UCG-013 exhibited an inverse association with the risk of developing erectile dysfunction (0.79 (0.65-0.97), P = 0.0214). Conversely, the genus Tyzzerella3 (1.13 (1.02-1.26), P = 0.0225), genus Erysipelotrichaceae UCG-003 (1.18 (1.01-1.38), P = 0.0412), genus LachnospiraceaeNC2004group (1.19 (1.03-1.37), P = 0.0191), genus Oscillibacter (1.23 (1.08-1.41), P = 0.0022), and family Lachnospiraceae (1.26 (1.05-1.52), P = 0.0123) demonstrated positive associations with an increased risk of erectile dysfunction. These sensitivity analyses of the gut microbiota were consistent. This study demonstrated a possible causal relationship between gut microbiota and erectile dysfunction risk through Mendelian randomization analysis, providing new potential possibilities for the prevention and treatment of erectile dysfunction.

Exploring the causal association between serum metabolites and erectile dysfunction: a bidirectional Mendelian randomisation study.

Erectile dysfunction is a common sexual disorder in men. Some studies have found a strong association between some serum metabolites and erectile dysfunction. To investigate this association further, we used bidirectional Mendelian randomisation to investigate causality and possible biological mechanisms.Firstly, this study screened the statistics of genome-wide association studies of serum metabolites and erectile dysfunction to obtain instrumental variables. Inverse variance weighting was used as the primary method for causal effect analysis of instrumental variables in forward or reverse Mendelian randomisation, and the results obtained by MR-Egger regression and the weighted median method were used as references. Subsequently, the metabolites causally associated with erectile dysfunction were subjected to replication analyses and meta-analyses, and the results of the meta-analyses were analysed by pathway analyses to find influential pathways. In this process, Mendelian randomisation results need to be assessed for stability and reliability using sensitivity analysis.It was found that a total of six serum metabolites were causally associated with erectile dysfunction in a forward Mendelian randomisation study. 1,3,7-trimethyluraten (0.85 (0.73-0.99), P = 0.0368), ergothioneine (0.65 (0.45-0.94), P = 0.0226) and gamma-glutamylglutamate (0.63 (0.46-0.88), P = 0.0059) were protective against the development of erectile dysfunction, whereas 2-hydroxyhippurate (1.10 (1.02-1.19), P = 0.0152), N2,N2-dimethylguanosine (1.57 (1.02-2.40), P = 0.0395) and octanoylcarnitine (1.38 (1.06-1.82), P = 0.0183) were able to induce the development of erectile dysfunction. In addition, metabolic pathway analysis showed that 1,3,7-trimethylurate was able to influence the development of erectile dysfunction via the caffeine metabolism pathway (P = 0.0454). On the other hand, reverse Mendelian randomisation analysis showed that erectile dysfunction reduced serum homocitrulline levels (0.99 (0.97-1.00), P = 0.0360). Sensitivity analyses, including heterogeneity tests and pleiotropy tests, confirmed the reliability of the results.In conclusion, this study demonstrated a bidirectional causal relationship between serum metabolites and erectile dysfunction using bidirectional Mendelian randomisation analysis and replication meta-analysis. On this basis, this study provides a new direction of thinking and strong evidence for the therapeutic application and adjunctive diagnosis of serum metabolites in erectile dysfunction, and provides a certain reference value for subsequent related studies.

[Anti-depressive effect of acupuncture on selective serotonin reuptake inhibitors].

OBJECTIVE: To evaluate anti-depressive effects of acupuncture on selective serotonin reuptake inhibitors (SSRIs). METHODS: Totally 60 patients with depression were randomly assigned to the control group (30 cases) and the treatment group (30 cases). All patients took one kind of SSRIs. Those in the treatment group were additionally treated by acupuncture. All were treated for 6 weeks. Patients' efficacies were evaluated with Hamilton Depression Scale (HAMD), Self-rating Depression Scale (SDS), and Eisenberg antidepressant side effects scale (Asberg). RESULTS: Compared with the control group after 6 weeks of treatment, the cured-markedly effective rate was improved by 33.4% in the treatment group (P < 0.05). The HAMD was lower in the treatment group. The tendency of interaction of sleep disorder factor and anxiety/somatization factor was different between at the end of 1-week treatment and at the end of 6-week treatment in the treatment group (P < 0.05). The SDS score decreased at the end of 6-week treatment in the treatment group. The reduction rate was elevated by 19.23% (P < 0.05). By the end of 6-week treatment, the average score of Asberg decreased by 3.77 score in average in the treatment group, while it decreased by 0.07 score in average in the control group (P < 0.05). CONCLUSION: Acupuncture could effectively improve anti-depressive effects of SSRIs and reduce their adverse reactions.

[Searching for dwarf nova candidates with automatic methods in massive spectra].

In the present paper, an automatic and efficient method for searching for dwarf nova candidates is presented. The methods PCA (principal component analysis) and SVM (support vector machine) are applied in the newly released SDSS-DR9 spectra. The final dimensions of the feature space are determined by the identification accuracy of training samples with different dimensions constrained by SVM. The massive spectra are dimension reduced by PCA at first and classified by the best SVM clas sifier. The final less number of candidates can be identified manually. A total number of 276 dwarf nova candidates are selected by the method and 6 of them are new discoveries which prove that our approach to finding special celestial bodies in massive spectra data is feasible. The new discoveries of this paper are added in the current dwarf nova template library which can contribute to constructing a more accurate feature space. The method proposed in this paper can also be used for special objects searching in other sky survey telescopes like Guoshoujing (Large Sky Area Multi-Object Fiber Spectroscopic Telescope -LAMOST) telescope.

High expression of TGF-ß1 in the vaginal incisional margin predicts poor prognosis in patients with stage Ib-IIa cervical squamous cell carcinoma.

This study evaluated the relationship between altered cytoplasmic expression of TGF-ß1 in tissues of the vaginal incisional margin and vaginal cancer recurrence in patients with stage Ib-IIa cervical squamous cell carcinoma (CSCC). This paper also discusses the prognostic value of TGF-ß1 expression at these locations. We found that TGF-ß1 expression in the vaginal margin had a close association with vaginal recurrence of stage Ib-IIa CSCC and was an independent prognostic marker of this disease.

DLEU7-AS1 promotes renal cell cancer by silencing the miR-26a-5p/coronin-3 axis.

Long non-coding RNAs (lncRNAs) have been implicated in the progression and development of many types of cancer by interacting with RNA, DNA and proteins, including DLEU7-AS1. However, the function of DLEU7-AS1 in renal cell cancer (RCC) remains unclear. In this study, two in silico prediction algorithms were used to discover the potential target of miR-26a-5p, which was determined to be a tumor suppressor gene, possibly DLEU7-AS1, through the downregulation of coronin-3 in RCC. Thus, we hypothesized that DLEU7-AS1 promotes RCC by silencing the miR-26a-5p/coronin-3 axis. To test our hypothesis, we confirmed that DLEU7-AS1 directly targets miR-26a-5p using the pmirGLO dual-luciferase reporter assay. Next, we observed that DLEU7-AS1 expression was markedly upregulated in RCC samples and inversely correlated with clinical prognosis and miR-26a-5p levels. Knockdown of DLEU7-AS1 significantly suppressed the growth and metastasis of RCC cells in vitro and attenuated tumor growth in vivo. Interestingly, exogenous expression of coronin-3 or miR-26a-5p inhibitor treatment almost completely rescued the DLEU7-AS1 knockdown-induced inhibitory effects on cell proliferation, migration and invasion. In conclusion, our data demonstrate that DLEU7-AS1 is an oncogene in RCC capable of regulating the growth and metastasis of RCC by silencing the miR-26a-5p/coronin-3 axis, suggesting that DLEU7-AS1 can be employed as a potential therapeutic target and prognostic biomarker for RCC.

LncRNA FAM13A-AS1 Promotes Renal Carcinoma Tumorigenesis Through Sponging miR-141-3p to Upregulate NEK6 Expression.

Long non-coding RNAs are a diverse catalog of RNAs that have been implicated in various aspects of tumorigenesis. Emerging evidence indicates that they play crucial roles in tumor growth, disease progression, and drug resistance. However, the clinical significance of lncRNAs in tumor behavior prediction and disease prognosis as well as the underlying mechanism in renal cell carcinoma (RCC) remains elusive. By analyzing the gene expression profiles of 539 RCC patients from the TCGA cohort and 40 RCC patients from an independent cohort, we identified FAM13A-AS1, a poorly studied lncRNA, upregulated in RCC patients. Knockdown experiments revealed that FAM13A-AS1 promotes cell proliferation, migration, and invasion by interacting with miR-141-3p. FAM13A-AS1 regulates the expression of NEK6 by decoying miR-141-3p. In addition, there was a strong positive correlation between the expression of FAM13A-AS1 and NEK6 in RCC patients. In summary, our results demonstrate the oncogenic role of FAM13A-AS1 in RCC and suggest that it promotes tumorigenesis by upregulating the expression of NEK6 by competitively binding to miR-141-3p.

[Analysis of food sources of Eriocheir sinensis in rice-crab integrated ecosystem based on stable isotopes in saline-alkali land of the Yellow River Delta]. / åŸºäºŽç¨³å®šåŒä½ç´ çš„é»„æ²³ä¸‰è§’æ´²ç›ç¢±åœ°ç¨»èŸ¹ç§å »ç³»ç»Ÿä¸­åŽç»’èž¯èŸ¹é£Ÿç‰©æºåˆ†æž.

To explore food composition of Chinese mitten crab (Eriocheir sinensis) in rice-crab integrated ecosystem in saline-alkali land of the Yellow River Delta, we analyzed carbon and nitrogen stable isotope ratios (δ13C and δ15N) in the crab and that in food sources, including plants (Elodea, Potamogeton crispus, Ceratophyllum demersum, Lemna minor, Oryza sativa stem and leaf, rice grain), animals (benthos, zooplankton), organic debris and artificial feed (compound feed, corn meal) in Kenli District, Dongying, Shandong Province in June to October of 2020. Substantial differences in δ13C and δ15N were found among food sources. The δ13C and δ15N values of different food sources were in a range of -30.09‰--11.24‰ and 0.03‰-12.78‰, respectively, while those of the crab muscle were in range of -24.61‰--20.08‰ and 4.74‰-9.21‰, respectively, indicating diverse food sources for the crab. During the experiment, the contribution rate of different food sources followed the order: plant (46.7%-57.1%)>animal (21.5%-24.5%)>artificial feed (10.9%-21.3%)>organic detritus (7.1%-7.9%). It suggested that the natural bait of the paddy field could meet the feeding needs of Chinese mitten crabs in saline-alkali land. Even the crabs were fed with non-animal artificial feed, the contribution rates of the main food sources were not altered.

Angiographic Characteristics of Cerebral Perfusion and Hemodynamics of the Bridging Artery After Surgical Treatment of Unilateral Moyamoya Disease.

Purpose: To investigate the characteristics of cerebral perfusion and hemodynamics of bypass grafting in the treatment of moyamoya disease (MMD) using the iFlow color-coded flow map in comparison with magnetic resonance imaging-perfusion-weighted imaging (MRI-PWI) and computational fluid dynamic (CFD) analysis. Materials and Methods: Patients with MMD treated with bypass grafting who had undergone MRI PWI and digital subtraction angiography for iFlow color-coded map was retrospectively enrolled and CFD was performed for calculating the hemodynamic stresses around the bypass grafting. Results: Forty-five patients with unilateral MMD treated with bypass surgery were enrolled. The bypass surgery was successful in all patients, with no severe neurological complications during the periprocedural period. Followed up for 4-12 months (median 5.5), the neurological function was good in all patients. The cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT), and time to peak (TTP) were significantly (p < 0.05) improved in the middle cerebral artery distribution area on the surgical side before and after vascular bypass, and the difference of TTP (s) measured from the proximal bifurcation of common carotid artery to the confluence of sinus was also significant (p < 0.05). A significant (p < 0.05) positive correlation existed in the perfusion parameters between the iFlow blood perfusion and the MRI-PWI perfusion, with r-value for TTP of 0.765 (p < 0.01). The iFlow color-coded blood flow map showed warm color changes on the diseased side, similar to those on the contralateral side. In CFD analysis, the hemodynamic stresses were all improved, in and around the bypass grafting and distal vessels, which were beneficial to blood flow entering distal arterial branches. Conclusion: The iFlow color-coded flow map can be used to analyze cerebral perfusion after bypass grafting for MMD, similar to MRI-PWI, and CFD can be used to analyze the hemodynamics after bypass grafting, revealing improved hemodynamics to promote blood flow entering distal arteries.

[Origin and development of HUA Tuo's acupuncturing sensation technique].

Based on HUA Tuo's personal experience, teaching experience, works as well as ancient books of similar times, this paper discusses the origin and development of HUA Tuo's acupuncturing sensation technique, and analyzes the reasons why this technology has been lost. The formation of this technique is influenced by the descriptions of "regulating qi " "arrival of qi " and "reaching qi" in Neijing (Internal Canon of Medicine) and Nanjing, and combines with the clinical summary of conduction direction and specific position of acupuncturing sensation. Due to HUA Tuo's personal experience, the inheritance characteristics of acupuncture technology and the background of his times, this technology may have been lost, but it still affects the acupuncture concept and practice of "qi reaching affected area" in later generations.

[A mechanism of endogenous opioid peptides for rapid onset of acupuncture effect in treatment of depression].

Clinical and experimental studies show that the onset of effect of acupuncture on depression is more rapid than selective serotonin reuptake inhibitors, a class of antidepressants. Acupuncture treatment is characterized by controlling anxiety and gastrointestinal discomfort. The onset time of acupuncture treatment for various pains is a week or so, which is the same as the rapid onset time of antidepressant effect of acupuncture, and the main pathway of acupuncture analgesia is through endogenous opioid system. Opioid peptides can produce pleasure, and decrease anxiety and gastrointestinal discomfort, so opioid peptides are considered to have antidepressant effect. Accordingly, the main pathway of acupuncture analgesia-the endogenous opioid system, is considered a mechanism for rapid onset of acupuncture effects on depression.

[Characteristics of clinical effectiveness of bloodletting and proposed ways of mechanism research].

According to the operative characteristics, the stimulated site and the curative effect-emerged site of bloodletting therapy, its clinical characteristics may be divided into three categories: a) local stimulation induced focus-local effect, b) local stimulation induced effect of the distal target organ (point-to-point distal effect), and c) special point stimulation induced broader effect of the whole body. Accordingly, the underlying mechanisms of clinical outcomes mainly involve the improvement of the local microcirculation and secondary changes of inflammatory substances for the first category (local focus). The point-to-point distal effect might mainly involve the innervation of nerve segments, while the broad effect of specific acupoint stimulation might involve multiple levels of the neuro-endocrine-immune system. The future research on the mechanisms of bloodletting should starts from its specific effects and the type of disease, which should not be generalized.

IDH1-R132H Suppresses Glioblastoma Malignancy through FAT1-ROS-HIF-1α Signaling.

BACKGROUND: Glioblastoma (GBM) is one of the most deadly primary malignant brain tumors in adults. R132H mutation of isocitrate dehydrogenase 1 (IDH1) predicts a better prognosis of GBM. IDH1-R132H is associated with increased hypoxia-inducible factor-1α (HIF-1α) expression in GBM tumors. However, the molecular mechanism underlying IDH1-R132H-HIF-1α signaling in GBM is still unclear. AIM: We aimed to investigate the molecular pathway of IDH1-R132H-HIF-1α in the regulation of GBM. MATERIALS AND METHODS: U87 and U251 GBM cells and xenograft tumor mice were used. RESULTS: We found that overexpression of IDH1-R132H decreased cell proliferation, increased apoptosis, decreased migration and invasion, enhanced temozolomide (TMZ)-induced cytotoxicity, and reduced tumor growth in xenograft mice. Overexpression of IDH1-R132H increased the expression of HIF-1α and downregulation of HIF-1α suppressed IDH1-R132H-induced effect on GBM. Reactive oxygen species (ROS) level was increased by IDH1-R132H over expression and the use of antioxidant inhibited IDH1-R132H-induced increase of HIF-1α expression. FAT Atypical Cadherin 1 (FAT1) expression was increased by IDH1-R132H over expression. Knockdown of FAT1 blocked IDH1-R132H-induced reduction of tumor growth in xenograft mice. Down regulation of FAT1 decreased HIF-1α expression and inhibited IDH1-R132H-induced increase of ROS level. CONCLUSIONS: Our findings provide new insights into IDH1-R132H-regulated downstream signaling in GBM and highlight the importance of IDH1-R132H-FAT1-ROS-HIF-1α signaling pathway in potential therapeutic intervention of GBM.

[Discussion on the needling technique with filiform needle in acupuncture-moxibustion teaching materials in the Republic of China].

Through collecting the literature data of the needling technique with filiform needle in 20 acupuncture-moxibustion teaching materials in the Republic of China， the manipulation techniques with filiform needle were analyzed, such as the technique of needle insertion, the technique of reinforcing and reducing, and the management of acupuncture abnormal conditions, as well as manual techniques and analgesics methods. It is found that the era of the Republic of China was the transition period of traditional acupuncture techniques to the modern ones in acupuncture-moxibustion teaching materials, in which, the twirling technique was predominated in the technique of needle insertion. In that period, the insertion technique of tube needle had been introduced and simplified, the theory and method of the new-style technique of reinforcing and reducing were emerged and the types of acupuncture abnormal conditions recorded in the teaching materials were different from those at present. Additionally, the applicable manipulation had not been specified nationally. There were the highly influential teaching materials, i.e. Advanced Acupuncture and Moxibustion Teaching Materials: Science of Acupuncture and Science of Moxibustion, Chinese Acupuncture and Moxibustion Teaching Materials and New Acupuncture and Moxibustion. The acupuncture-moxibustion teaching materials in the Republic of China has been influenced by the transition of acupuncture-moxibustion education modes, the introduction of Chinese-translation version of Japanese acupuncture-moxibustion books, the academic thoughts of acupuncture masters and the manufacturing process of needle devices.

Auricular Intradermal Acupuncture as a Supplementary Motor Rehabilitation Strategy in Poststroke Patients: A Randomized Preliminary Clinical Study.

We have explored the potential of auricular intradermal acupuncture (AIA) in standard rehabilitation and acupuncture treatment for motor recovery in poststroke patients. This was a randomized, controlled preliminary clinical study in which the patients were randomly assigned to the CT group (conventional treatment, standard rehabilitation, and routine acupuncture) or AIA group (AIA combined with conventional treatment) and underwent 6 sessions in 1 week (6 days). Standard procedures and previously reported acupuncture points were used. Clinical outcomes were measured by the Fugl-Meyer motor assessment (FMA) of flexor and extensor synergy movement (FSM and ESM) of the upper and lower extremities (UE and LE) at days 0, 3, and 6. The assessment was performed by blinded assessors. The AIA group showed a significant increase in FMA-UE/FMA-LE scores on day 3 (P=0.012 and 0.001, respectively) and day 6 (P=0.041 and P < 0.001, respectively), but this was not observed in the CT group. Furthermore, unlike the CT group, the AIA group exhibited a significant increase in the FMA-LE score on day 3 (P=0.004) and the FMA-UE scores on day 6 (P=0.048). Finally, the correlation between ESM and FMA-UE/FMA-LE was higher than that between FSM and FMA-UE/FMA-LE after treatment: for ESM and UE, r = 0.759, P=0.007; for ESM and LE, r = 0.697, P=0.003; for FSM and UE, r = 0.604, P=0.049; for FSM and LE, r = 0.347, P=0.188. AIA is useful for motor rehabilitation in poststroke patients, particularly in terms of improving extensor synergy. This trial is registered with CHiCTR1800020150.

Serum C-reactive protein (CRP) and microalbuminuria in relation to fasting and 2-h postload plasma glucose in a Chinese population.

OBJECTIVE: Serum C-reactive protein (CRP) and microalbuminuria are predictors of cardiovascular disease. The association of these factors of cardiovascular risk with fasting and 2-h postload plasma glucose in a group of Chinese subjects was investigated. DESIGN: This was a cross-sectional cohort study. SUBJECTS AND METHODS: In 1776 subjects randomly selected from the permanent residents of a community in the city of Shanghai, China, a simplified 75-g oral glucose tolerance test (fasting and 2-h postload blood sampling only) was performed, and serum CRP concentrations and urinary albumin : creatinine ratio were measured. RESULTS: Serum CRP concentration significantly increased from 1.62 mg/l in normoglycaemic subjects to 2.63 mg/l in subjects with impaired glucose regulation, and to 3.09 mg/l in newly diagnosed diabetic patients (P < 0.0001). The corresponding prevalence of microalbuminuria also increased from 4.3% to 6.6% and to 11.4% (P < 0.0001). Both before and after adjustment for confounders, fasting and 2-h postload plasma glucose levels were significantly associated with serum CRP concentration and the risk of microalbuminuria (P < 0.003). However, the association for CRP tended to be more prominent with 2-h postload plasma glucose than with fasting plasma glucose. Indeed, with adjustments applied, for 1 SD change in fasting and 2-h postload plasma glucose concentration, serum CRP concentration increased by 14% and 18% (between the two regression coefficients, P = 0.01), respectively. With similar adjustments, for 1 SD change in fasting and 2-h postload plasma glucose concentration, the odds of microalbuminuria increased by 28% and 32% (P = 0.28 for the difference between 28% and 32%), respectively. CONCLUSIONS: Our finding suggests that in Chinese plasma glucose, especially 2-h postload, is associated with biological markers of cardiovascular disease, such as serum CRP concentration and microalbuminuria.
