ObjectiveTo observe the effect of early bilateral limbs rehabilitation on nerve function of stroke patients.Methods60 cases of acute stroke were divided into unilateral group and bilateral group with 30 cases in each group. Cases in bilateral group were treated by training healthy side and sick side limbs alternatively and electric stimulating bilateral limbs at same time. Cases in unilateral group were treated only on sick limbs (both training and electric stimulating). After 4 weeks treatment, neurological deficit evaluation (NDE), motor function and activities of daily living of all cases in two groups were assessed.ResultsAfter treatment, scores of NDE, Fugl-Meyer Motor Assessment Scale and Barthel index of patients of bilateral group were 9.9±4.52, 71.21±22.43 and 78.6 ± 20.17 respectively. Those of patients of unilateral group were 13.46±9.2, 52.21±17.68 and 54.2±16.34 respectively. There was a significant difference between two groups (P<0.01) after 4 weeks treatment.ConclusionEarly rehabilitation can improve nerve function of stroke patients and the effect of bilateral limbs rehabilitation is better than that of unilateral limbs rehabilitation.

Objective To develop a diabetes risk score (DRS)to predict the risk of development of incident diabetes in male senile people in Beijing. Methods DRS was developed basing on a test group including a cohort of 1 370 individuals aged 48-87 years without diabetes at baseline, followed for 10 years by Logistic regression and validated on a value group including a cohort of 340 individuals aged 43-88 years without diabetes at baseline. Results The model with the highest area under the ROC curve ( AUC ) included age, hypertension,history of hyperglycemia, body mass index, fasting plasma glucose, triglycerides, and high-density lipoproteincholesterol (HDL-C). DRS was developed basing on this model with a range from 0 to 12 and an optimal cut-off of 4. AUC were respectively 0. 726 ( 95% CI0. 692-0. 759 ) and 0. 765 ( 95% CI0. 691-0. 839 ) in test group and validation group. The sum score value ≥4 had sensitivity of 65.3% and 68. 1%, specificity of 70. 0% and 64.8%, positive predictive value of 37.0% and 23.2%, negative predictive value of 88.2% and 94. 1%.Conclusion The DRS, derived from clinical information combined with plasma glucose and lipids, is an effective tool to predict incident diabetes.

Subtelomeric rearrangements contribute to idiopathic mental retardation (MR), but most children with idiopathic MR do not show any chromosome abnormalities with standard cytogenetic analysis. The primed in situ labeling (PRINS) technique, using an oligonucleotide primer complementary to the telemetric repeat sequences (TTAGGG), can identify chromosome telomeric abnormality (deletion) in idiopathic MR children. In this study, seventy children with idiopathic MR were enrolled and subjected to PRINS. The results showed normal karyotype in all the children, subtelomeric rearrangements (1q del and 4q del) in 2 cases, which was confirmed by fluorescence in situ hybridization (FISH). It was concluded that PRINS is effective for the detection of subtelomeric rearrangements and may become a routine technique for cytogenetical abnormality screening.

Objective To investigate the proliferation and analyze the protein expression of the Hela cells by the regulation of glyceryl trinitrate (GTN) that acts as the donor of nitric oxide.Methods Cell morphology and MTT assay were used to analyze cell proliferation.Two-dimensional polyacrylamide gel electrophoresis (2-DE) and computer-assisted image analysis find the spots of interests.

Some atypia cells were observed.Density of the cells was obviously decreased(0.0825, P

Objective To investigate the effect of angiotensin Ⅱ(Ang Ⅱ)on the expression of integrin-linked kinase(ILK)in rat glomerular mesangial cells.Methods SD rat glomerular mesangial cells were separated and cultured.They were treated with 10-7 mol/L Ang Ⅱ in various time-point(0,12,24,48,72 h),and then cultured rat glomerular mesangial cells were treated 48 h with Ang Ⅱ in various concentration(0,10-11,10-9,10-7,10-5 mol/L).Then total protein expression in rat glomerular mesangial cells stimulated by Ang Ⅱ at every time-point and every concentration-point was extracted.The expression of ILK protein was measured by Western blot.Results 1.Expression of ILK protein in rat glomerular cells stimulated by Ang Ⅱ in various time-point,or various concentration was significantly increased.In group of 10-7 mol/L Ang Ⅱstimulated cells,the protein semiquantity of ILK at 0,12,24,48,72 h respectively was 0.18?0.02,0.37?0.07,0.90?0.10,1.73?0.12,and 1.72?0.13(F=166.78 P

OBJECTIVETo investigate the risk factors for the occurrence of patent ductus arteriosus (PDA) and to provide a clinical basis for reducing the occurrence of PDA in early preterm infants.

METHODSA total of 136 early preterm infants (gestational age≤32 weeks) who were hospitalized between January 2013 and December 2014 and diagnosed with hemodynamicalhy significant PDA (hs-PDA) were enrolled as the case group. Based on the matched case-control principle, 136 early preterm infants without hs-PDA were selected among those who were hospitalized within the same period at a ratio of 1:1 and enrolled as the control group. The two groups were matched for sex and gestational age. The basic information of neonates and maternal conditions during the pregnancy and perinatal periods were collected. Logistic regression analysis was performed to identify the risk factors for the development of PDA.

RESULTSUnivariate analysis showed that neonatal infectious diseases, neonatal respiratory distress syndrome, decreased platelet count within 24 hours after birth, and low birth weight were associated with the development of hs-PDA (P<0.05). Multivariate conditional logistic regression analysis revealed that neonatal infectious diseases (OR=2.368) and decreased platelet count within 24 hours after birth (OR=0.996) were independent risk factors for hs-PDA.

CONCLUSIONSNeonatal infectious diseases and decreased platelet count within 24 hours after birth increase the risk of hs-PDA in early preterm infants.

ObjectiveTo investigate the mechanism and prevention of invisible injury of recurrent laryngeal nerve (RLN) system in thyroid surgery, with the application of intraoperative neuromonitoring ( IONM ) system. MethodsThe type of invisible RLN injury and its protection with the application of IONM system were analyzed. ResultsThe causes of invisible RLN injury mainly included stretching of Berry ligament or the tumor,contusion, thermal injury, cutting of silk and suction injury. RLN invisible injury was recoverable through neurotrophic and symptomatic treatment. No permanent vocal cord paralysis occurred. ConclusionsWith the application of IONM system, some invisible type of RLN injuries can be found. The risk of RLN injury can be reduced if the surgical techniques are improved with the development of study on mechanism of IONM system.

Objective To analysis the immunological characteristics of patients with severe H1N1 influenza A, and to provide theoretical basis for predicting the prognosis of the disease. Methods A retrospective analysis was conducted. The clinical data of 15 patients diagnosed with severe H1N1 influenza A and admitted to Shanghai General Hospital of Nanjing Medical University from October 2015 to December 2016 were collected. All the patients were divided into survival and death groups according to 28-day survival. Clinical characteristics, treatment algorithm, organ function, inflammatory reaction and immune cell status were compared, and Cox regression was used to decide the risk factors of 28-day death in patients with severe H1N1 infection A. Results All 15 patients with severe H1N1 infection A were enrolled, most of who presented with cough (93.3%), fever (86.7%), sputum production (80.0%), shortness of breath (73.3%), myalgia (40.0%) and fatigue (40.0%). All had been received anti-virus, antibiotics, mechanical ventilation and anti-coagulation therapy; some were treated with prone position, neuromuscular blocker and extracorporeal membrane oxygenation (ECMO). The incidences of acute myocardial and kidney injury were high, and the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score (14.1±6.1) and sequential organ failure assessment (SOFA) score (9.6±4.1) implicated the critical condition. Of 15 patients, 4 patients died in 28 days, while 11 were cured and discharged. Compared with survival group, the patients in death group had higher levels of APACHE Ⅱscore (22.7±3.8 vs. 11.8±3.8), troponin [cTn (μg/L): 0.52 (0.07, 2.02) vs. 0.15 (0.10, 0.45)] and blood urea nitrogen [BUN (mmol/L): 11.9 (6.7, 29.1) vs. 3.9 (2.7, 6.8)] and a lower level of blood platelets count [PLT (×109/L): 76±33 vs. 146±49, all P < 0.05]. The levels of C-reactive protein (CRP) and interleukin-6 (IL-6) within 24 hours of admission in death group were significantly higher than those of survival group [CRP (mg/L): 172.2±88.5 vs. 74.8±33.1, IL-6 (ng/L):283.3 (140.1, 711.0) vs. 18.5 (12.7, 71.4), both P < 0.01]. Compared with survival group, the expressions of CD3+, CD4+, CD8+ T cells and natural killer cell (NK cell) in death group were significantly decreased (CD3+ T cell: 0.348±0.119 vs. 0.573±0.106, CD4+ T cell: 0.135±0.046 vs. 0.344±0.098, CD8+ T cell: 0.089±0.057 vs. 0.208±0.054, NK cell: 0.124±0.057 vs. 0.252±0.182, all P < 0.05), but there were no significant differences in CD4+/CD8+ ratio and human leucocyte antigen-DR positive (HLA-DR+) T cell between death group and survival group (CD4+/CD8+ ratio:1.57±0.26 vs. 1.83±0.54, HLA-DR+ T cell: 0.035±0.022 vs. 0.062±0.036, both P > 0.05). B lymphocyte in death group was significantly higher than that of survival group (0.477±0.136 vs. 0.229±0.121, P < 0.01). Cox regression analysis revealed that APACHE Ⅱ score [risk ratio (RR) = 20.4, 95% confidence interval (95%CI) = 5.3-31.2, P = 0.017], CD4+ T cell (RR = 11.1, 95%CI = 5.1-20.0, P = 0.048) and CD8+ T cell (RR = 9.1, 95%CI = 4.3-16.7, P = 0.049) were independently risk factors of 28-day survival of patients with severe H1N1 influenza A. Conclusion Immunological paralysis and severe inflammatory response were early complicated with severe H1N1 influenza A, and these were significantly associated with prognosis.
