Patients often suffered limb dysfunction after stroke. Upper limb and hand function recovered more slowly than lower limb, and became one of the research focuses in rehabilitation medicine. Timely and effective assessments were important to guide the rehabilitation treatment, evaluate the treatment efficacy and predict functional recovery of upper extremity and hand function. The assessment methods of upper limb and hand motor function included subjective evaluations and objective evaluations. The former included different kinds of scales, which involved assessment focusing on muscle, motor pattern, change of upper limb and hand function. While the latter contained biomechanics, neuroelectrophysiology, functional magnetic resonance imaging, upper limb robotic evaluation system and so on. Scales were proved to have good reliability and validity. But they could not show patients' function accurately because of the subjectivity, and the data could not be kept. Evaluation system with computer was applied in clinical practice more and more widely. In this review, we summarized the assessments on upper limb and hand motor function in patients after stroke.

Objective:To investigate the diagnostic value of mitochondrial associated protein fumarylacetoacetate domain containing protein 1 (FAHD1) and growth differentiation factor-15 (GDF-15) in sepsis.Methods:Based on the database of the whole process of sepsis early warning, diagnosis and treatment management, which was established on the study of sepsis early warning and standardized diagnosis and treatment system, adult patients with suspected infection admitted to the department of critical care medicine of Zhejiang Hospital, Second Affiliated Hospital of Zhejiang University, the First Affiliated Hospital of Sun Yat-Sen University, West China Hospital of Sichuan University, Ningbo First Hospital from May 2014 to October 2015 were enrolled. The basic vital signs, and the main blood routine results, liver and kidney function, blood gas, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) and sequential organ failure assessment (SOFA) score at the time of diagnosis of patients with or without sepsis were analyzed. The preserved serum samples were taken, the levels of procalcitonin (PCT), C-reactive protein (CRP) were detected by electrochemiluminescence method, immunoturbidimetry respectively, and FAHD1 and GDF-15 were detected by enzyme linked immunosorbent assay (ELISA). Univariate and multivariate Logistic regression were used to analyze the risk factors for sepsis diagnose. The indexes' diagnostic efficacy in sepsis were analyzed by receiver operating characteristics curve (ROC curve).Results:A total of 132 patients were enrolled, including 76 cases of sepsis and 56 cases of non-sepsis. Compared with the non-sepsis group, the heart rate in the sepsis group was increased (bpm: 116.4±17.8 vs. 97.4±19.1), while the mean arterial pressure (MAP), platelet count (PLT), arterial partial pressure of oxygen (PaO 2) were significantly decreased [MAP (mmHg, 1 mmHg = 0.133 kPa): 65.8±9.7 vs. 74.7±10.3, PLT (×10 9/L): 120 (69, 204) vs. 163 (117, 239), PaO 2 (mmHg): 83.0 (66.6, 108.0) vs. 108.0 (84.4, 130.0), all P < 0.05], direct bilirubin (DBil), serum creatinine (SCr), lactic acid (Lac), APACHEⅡ score and SOFA score were significantly increased [DBil (μmol/L): 13.00 (5.55, 55.31) vs. 6.20 (2.20, 21.90), SCr (μmol/L): 118.00 (70.00, 191.73) vs. 77.20 (59.65, 110.86), Lac (mmol/L): 2.90 (1.50, 4.10) vs. 1.90 (1.20, 2.80), APACHEⅡ score: 20.0 (16.0, 25.0) vs. 16.0 (10.0, 21.0), SOFA score: 12.0 (8.0, 16.0) vs. 8.0 (5.0, 13.0), all P < 0.05]. In addition, the serum levels of FAHD1, GDF-15, PCT and CRP in sepsis group were significantly higher than those in non-sepsis group [FAHD1 (μg/L): 3.96 (2.25, 5.92) vs. 2.47 (1.03, 3.54), GDF-15 (μg/L): 8.46 (4.37, 19.68) vs. 4.32 (1.74, 10.39), PCT (μg/L): 3.79 (1.37, 11.32) vs. 0.42 (0.12, 2.14), CRP (mg/L): 154.43 (61.33, 283.20) vs. 65.95 (28.15, 144.69), all P < 0.01]. Multivariate Logistic regression showed that serum FAHD1 [odds ratio ( OR) = 1.135, 95% confidence interval (95% CI) was 1.045-1.234], GDF-15 ( OR = 1.090, 95% CI was 1.029-1.155) and CRP ( OR = 1.007, 95% CI was 1.002-1.011) were risk factors for sepsis (all P < 0.05). ROC curve analysis of sepsis showed that the areas under ROC curve (AUC) of serum mitochondrial associated proteins FAHD1 and GDF-15 were 0.727 (95% CI was 0.641-0.802) and 0.677 (95% CI was 0.588-0.757), respectively; and the AUC of classical infection indexes PCT and CRP were 0.767 (95% CI was 0.683-0.837) and 0.680 (95% CI was 0.59-0.760), respectively. There was no significant difference between the AUC of mitochondrial associated proteins and classical infection indexes. The combination of FAHD1, GDF-15, PCT and CRP had the largest AUC, which was 0.809 (95% CI was 0.730-0.874), and the sensitivity was 75.00%, and the specificity was 80.00%. Conclusion:Mitochondrial associated protein FAHD1 and GDF-15 are associated with sepsis, and the diagnostic efficiency is improved when combined with PCT and CRP, which might provide experimental basis for screening diagnostic markers of sepsis.

Objective To observe the effects of gossypol on expressions of transforming growth factor-β1 (TGF-β1), fibronectin (FN) and 11β-hydroxysteroid dehydrogenase (11β-HSD) in nephridial tissue in rats with diabetes mellitus. Methods Thirty male Sprague-Dawley rats were randomly divided into three groups: normal control, type 2 diabetes and gossypol treatment group . After high-fat feeding for 4 weeks, the later two groups were injected with low dosage strepozotocin (30 mg/kg) intraperitoneally to induce type 2 diabetic rat model. The rats in gossypol treated group were given gossypol at the dosage of 15 mg/kg once per day for 4 weeks by gavage. And since the 5th week, the times of gavages had been changed into once per week at the same dosage and lasted to the 12th week . The levels of blood glucose, total cholesterol (TC), low density lipoprotein-cholesterol (LDL-c) were measured. Additionally, the morphological changes of the kidney were studied by light microscopy and transmission electron microscopy respectively. The mRNA expressions of TGF-β1, FN, 11β-HSD and 11β-HSD2 in nephridial tissue were assayed by semi-quantity RT-PCR. The protein expressions of TGF-β1 and FN in nephridial tissue were determined by immunohistochemistry. Results The blood levels of glucose, TC and LDL- c were increased significantly in type 2 diabetic group compared with normal control group(P<0. 01). The volume of glomerulus and the deposition of PAS positive substance in the glomerular interstitium were increased under light microscopy, and the glomerular basal membrane was thicker in type 2 diabetic group than those in normal control group under transmission electron microscopy. The mRNA and protein expressions of TGF-β1 and FN were increased(P<0. 01), and the mRNA expression of 11β-HSD2 was decreased(P<0. 05), while the mRNA expression of 11β-HSD1 was unchanged in type 2 diabetic group compared with normal control group. After the treatment of gossypol, the level of the blood glucose was significantly decreased(P< 0. 01), and the levels of TC, LDL-c showed a trend of decrease but had no statistical differences compared with type 2 diabetic group. The morphology of nephridial tissue was ameliorated in gossypol treatment group. The mRNA and protein expressions of TGF-β1 and FN were decreased(0. 16± 0. 02,0. 22±0. 05 ; 0. 24±0. 06,0. 33±0. 07, P< 0. 05), while the mRNA expressions of 11β-HSD1 and 11β-HSD2 were unchanged compared with type 2 diabetic group. Conclusions Gossypol can relieve the pathologic changes of nephridial tissue, inhibit the expressions of TGF-β1 and FN through decreasing blood glucose of rats with diabetes mellitus.
