ABSTRACT

Alzheimer's disease (AD) is associated with the impairment of white matter (WM) tracts. The current study aimed to verify the utility of WM as the neuroimaging marker of AD with multisite diffusion tensor imaging datasets [321 patients with AD, 265 patients with mild cognitive impairment (MCI), 279 normal controls (NC)], a unified pipeline, and independent site cross-validation. Automated fiber quantification was used to extract diffusion profiles along tracts. Random-effects meta-analyses showed a reproducible degeneration pattern in which fractional anisotropy significantly decreased in the AD and MCI groups compared with NC. Machine learning models using tract-based features showed good generalizability among independent site cross-validation. The diffusion metrics of the altered regions and the AD probability predicted by the models were highly correlated with cognitive ability in the AD and MCI groups. We highlighted the reproducibility and generalizability of the degeneration pattern of WM tracts in AD.

ABSTRACT

, known as gold-needle master has its own unique academic system in the treatment of stroke. In view of principle, rule, recipe, acupoint and technique, 's academic thoughts were reviewed in the treatment of stroke. In terms of theoretic foundation, treating principles, formula application, rules of acupoint selection and manipulation techniques, the characteristics on the academic thoughts on the treatment of stroke were explained. Professor believes that stroke is caused by deficiency, fire, wind, phlegm, and blood. Promoting meridian and collateral circulation, regaining consciousness and cultivating functions are the treating principles. The acupoint application is characterized as the acupoint selection by stages and the combination of local points with the points in the front and on the back. The penetrating-needling technique and moxibustion are predominated in the treatment.

ABSTRACT

Objective To evaluate the effectiveness of radial extracorporeal shockwave therapy(rESWT) for the treatment of superior lateral brachial cutaneous nerve(SLBCN) compression syndrome.Methods A total of 40 patients with SLBCN compression syndrome who were treated in our department from March 2013 to October 2015 were equally randomized into two groups according to random number table:rESWT group(treated with rESWT for 1 cycle) and control group(treated with local hormone injection for 1 cycle). Visual analogue scale(VAS) and Constant-Murley scale(CMS) were applied to evaluate the shoulder joint function before treatment and 1 month and 1 year after treatment. Results The average CMS scores were(66.7±0.9) and(65.7±1.1)scores in rESWT group and control group,respectively,before treatment(t=0.67,P=0.510) and were(86.9±1.0) and(86.4±1.1)scores one month after treatment(t=0.35,P=0.730);it increased to(89.7±0.7) scores in rESWT group one year later,which was significantly higher than that in control group[(85.3±0.8)scores](t=3.56,P=0.002). The improvement rate was 95% in rESWT group and only 75% in control group. Before treatment,the median VAS score in rESWT group and control group were 5.00(5.00,6.00) and 5.00(4.00,5.75)scores(u=1.13,P=0.29);one month after treatment,the median VAS score in these two groups were 2(1.00,2.75) and 2.00(1.00,2.00)scores(u=0.04,P=0.85);one year later,it was 1.00(0.00,1.00) scores in rESWT group,significantly lower than that in [2.00(1.00,2.00)scores] control group(u=5.09,P=0.02). Conclusion Compared with local hormone injection,rESWT can remarkably alleviate pain and restore shoulder joint function in patients with SLBCN compression syndrome after one year of treatment.

ABSTRACT

Iron-doped titanium dioxide nanosheets was prepared by hydrothermal method using tetrabutyl titanate (C16H36O4Ti) and iron trifluoride (FeF3) and modified on ITO electrode.ITO/Fe : TiO2/CdS photoelectrochemical sensor was fabricated by successive ionic layer absorption and reaction(SILAR) method for determination of copper ion.The band gap of electode material was narrowed by iron doped TiO2 nanosheets,which made its absorption red-shifted and its response range of light was magnified.Based on the sensitization effect of CdS,the absorption and utilization of visible light of sensor was significantly enhanced and the photoelectric signal was amplified via reducing the recombination of electrons and holes.The sensor displayed excellent analytical performance for detection of copper ion with linear range of 0.2-4.0 μmol/L and 4.0-80.0 μmol/L and with the detection limit of 85 nmol/L.The sensor was used to detect copper ion in tap water,drinking water and Yongjiang river water with recoveries ranging from 94% to 111%.

ABSTRACT

Objective To study the effects on anterosuperior stability of the shoulder joint when the coracoacromial arch is damaged at different degrees. Methods Thirty-six specimens of the fresh frozen adult shoulder joints were randomly and evenly divided into 3 groups. Group 1, reserving integrity of the coracoacromial ligament of the shoulder joint; Group 2, dissecting half of the coracoacromial ligament attachment sector on the acromion; Group 3, grinding all the coracoacromial ligament attachment sector on the acromion. The specimens of the shoulder joint were fixed on test bench of the biomechanical testing machine. The axial pressure was applied on the humeral shaft, and the humeral head was pushed to move in anterosuperior direction. The displacement distance of the humeral head under 50 N pressure was then recorded. Results Under 50 N pressure, the displacement distance of the humeral head in Group 1, 2, 3 was (2.50±0.59), (5.38±0.71), (6.49±0.81) mm, respectively, which showed significantly statistic differences among 3 groups (P<0.05). Conclusions The damage to the coracoacromial arch will affect the anterosuperior stability of the shoulder joint. The greater damage to the coracoacromial arch will lead to the lower anterosuperior stability of the shoulder joint.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the role of Pediatric Critical Illness Score (PCIS) in evaluating the prognosis and severity of severe hand-foot-mouth disease (HFMD).</p><p><b>METHODS</b>This study included 424 children with severe HFMD, consisting of 390 survivors and 34 deceased patients. Related physiological parameters and clinical data were collected for calculating PCIS scores. The area under receiver operating characteristic curve (AUC) was employed to assess the performance of PCIS in evaluating the complications and outcomes.</p><p><b>RESULTS</b>The median of PCIS scores for survivors was higher than that for deceased patients (P<0.01). Of the 424 children with severe HFMD, only 26 (6.1%) had critical illness according to the severity assessment using PCIS. The AUC (95%CI) of PCIS was 0.74 (0.66, 0.82) in predicting pulmonary edema, 0.82 (0.74, 0.90) in predicting pulmonary hemorrhage, and 0.83 (0.75, 0.92) in predicting death.</p><p><b>CONCLUSIONS</b>PCIS can predict the complications and prognosis in children with severe HFMD. However, the existing scoring system of PCIS cannot fully assess the severity of HFMD.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the characteristics of children with acute pancreatitis and provide the basis of early diagnosis and treatment.</p><p><b>METHODS</b>Totally 121 children with acute pancreatitis admitted to Hunan Children's Hospital between March 2003 and December 2009 were enrolled in this retrospective study. The data of clinical manifestations, biochemical examinations, imaging and prognosis were summarized and statistically analyzed.</p><p><b>RESULTS</b>Of the 121 cases, preschool and school-age children were the main groups, and the prevalent months were May and June. Abdominal pain (88.4%) and vomiting (61.2%) were the major initial symptoms of pancreatitis in children, but none of children under the age 1 year complained of abdominal pain; 70.2% had signs of abdominal tenderness, accompanied by abdominal rigidity, distension, hepatomegaly, jaundice, etc. Severe patients developed shock, convulsions, coma and so on. Serum amylase concentration increased to above the upper reference limit in 114 children (94.2%) when they admitted within 24 hours after admission. Urine amylase elevation was noted in 77 children (79.4%). The amylase concentration decreased after 3 days, but not all returned to normal 14 days afterward. Children with sustained serum amylase elevation or serum amylase level ≥ 3 times upper limit of normal range more likely to have fever, vomiting, abdominal distension, and pancreatic abnormalities at ultrasonography or CT which showed that the echo of pancreas decreased or enhanced, pancreas edema, pancreatic duct expanded, etc. Abdominal ultrasonography and CT showed that 75 cases (62.0%) had other organ damage besides pancreatitis, liver (25.3%) and intestinal (16.0%) damages were very common, while liver and myocardial damages were seen frequently in the laboratory examinations, which complicated with serum ALT/AST, total bilirubin, blood glucose elevation and myocardial enzyme abnormalities. Several gastroscopic examinations showed mucosal hyperemia and edema, sheet-like erosion, etc. Except for one case who underwent laparotomy, all the remaining children were treated with non-operative comprehensive treatment. Of them 119 were cured or improved, 2 died and 5 had recurred disease later.</p><p><b>CONCLUSIONS</b>Gastrointestinal symptoms were the main clinical manifestations of acute pancreatitis in children, often complicated with extrapancreatic damage. The younger the patient was, the less complaint of abdominal pain they had. This indicates that acute pancreatitis should be considered when children suffered from acute abdominal pain and vomiting which had no known cause or could not be explained. It is important to do take serial monitoring of serum amylase, and imaging procedures.</p>

ABSTRACT

@#BACKGROUND: Pancreatic damage in critically ill patients is associated with the progressive failure of multiple organs, but little is known about its clinical characteristics. At present, no guidelines are available for the diagnosis and management of pancreatic damage. This study was undertaken to analyze the clinical and pathologic characteristics of pancreatic necrosis in critically ill children, and to find some biological markers of pancreatic damage or pancreatic necrosis. METHODS: We retrospectively reviewed the clinical data, laboratory results, and autopsy findings of 25 children, who were admitted to Hunan Children's Hospital, China from 2003 to 2009, and died of multiple organ failure. The autopsy revealed pancreatic necrosis in 5 children, in whom sectional or gross autopsy was performed. RESULTS: The 5 children had acute onset and a fever. Two children had abdominal pain and 2 had abdominal bulging, flatulence and gastrointestinal bleeding. Four children had abnormal liver function, characterized by decreased albumin and 3 children had elevated level of C-reactive protein (CRP). B-ultrasonography revealed abnormal acoustic image of the pancreas in all children, and autopsy confirmed pancreatic necrosis, which may be associated with the damage of the adrenal gland, liver, lung, heart, spleen, kidney, intestine, thymus, mediastinal and mesenteric lymph nodes and other organs. Children 1 and 2 died of acute hemorrhagic necrotizing pancreatitis (AHNP);children 3-5 died of multiple organ dysfunction syndrome (MODS) due to pancreatic necrosis. CONCLUSION: Pancreatic damage or pancreatic necrosis in critically ill children is characterized by acute onset, severity, short course, multiple organ damage or failure. It may be asymptomatic in early stage, and easy to be ignored.

ABSTRACT

<p><b>OBJECTIVE</b>To understand the perception on roles of gender and decision-making regarding family affairs among married women and its impact on the utilization of perinatal care.</p><p><b>METHODS</b>Clustering sampling was conducted to select 1227 married women with at least a child aged from 0 to 7 years old, from Hebei, Hubei and Sichuan provinces. All women were interviewed using a uniform questionnaire during Nov.-Dec. 2004.</p><p><b>RESULTS</b>The overall proportion of women who had relatively poor perception of gender role was 65.1%. 59.3% of the women agreed that "husband's health is more important than wife's in the family" versus 39.7% of interviewed women agreed that "man is more suitable for leadership than woman". In 46.2% of the families, wife and husband shared the responsibility of decision making on family affairs. In 16.2% of the families women played a decisive role, while 67.1% of interviewed women had to get the approval of her husband when spending money on daily necessities. When there were different opinions between the couples, husband usually made the final decision in 20.5% of all the families versus 17.4% of families where wife made the final decision. In total,the proportion of women who had somehow rights on family affairs was 64.1%. The coverage rate of antenatal care was 91.0%, and 65.3% women who received antenatal care got the first antenatal visit during the first trimester and the proportion of women who had at least five antenatal visits was 39.7%. The institutional delivery was 59.3% among all the women. Perception of gender role was not a predictor for antenatal care utilization, but it was predictive of institutional delivery. Education was quite a significant predictor on perinatal care utilization.</p><p><b>CONCLUSION</b>Efforts should be strengthened to improve women's awareness and to increase their perception on gender role in the families so that more women could achieve quality perinatal care.</p>
