ObjectiveTo study the clinical characteristics of the temperature instability in Prader-Willi syndrome (PWS). MethodsThe clinical characteristics of one case of PWS with recurrent fever were retrospectively analyzed.ResultsA 5-month-old boy who had such clinical characteristics as low central muscle tension, sucking weakness, feeding dififculties, cryptorchidism and white skin was diagnosed as PWS by chromosomal microarray analysis and methylation-speciifc PCR. In the course of the disease, the infant presented recurrent fever. The pathogenic bacteria culture and virus antibody detection showed negative, and the treatment of reducing fever, anti-infection and immune support were ineffective.ConclusionsThe cause of the recurrent fever is unknown and central fever is suspected. Whether the temperature instability is the clinical feature of PWS still needs a lot of clinical researches.

Objective To analysis the long-term retention rate of Levetiraceram (LEV) monotherapy or combination therapy of infant epilepsy. Methods The clinical data of patients with infant epilepsy treated by LEV had been retrospectively analyzed from July 2006 to June 2007. Results Sixty patients with infant epilepsy treated by LEV had been recruited, 20 cases with partial seizures, 19 cases with generalized seizures, 21 cases with epilepsy syndrome. Among them 21 cases was intractable epilepsy. The retention rates of LEV in 6-month, 1-year, 2-year, 3-year and 4-year were 95.5%, 75.0%, 60.0%, 51.7%, and 38.3%. The most common reason for withdrawal was lack of effect (43.2%). COX regression model suggested that duration>1 month (RR=2.91, 95%CI:1.16~7.30) and refractory epilepsy (RR=2.30, 95%CI:1.22~4.32) were risk factors of withdrawal (all P<0.05). After treatment, the seizure frequency signiifcantly reduced compared with baseline (P<0.01). To the end of the follow-up, the efifciency was 100%and the complete remission rate was 69.57%in 23 cases continued treatment. The main side effect were fatigue (56.0%), and sleep increased, irritability, and so on. Conclusions LEV monotherapy or combination therapy has well long-term retention rate, maintains well efifcacy and tolerability in infant epilepsy.

This study was to explore a better three-dimensional (3-D) culture method of chondrocyte. The interpenetrating network (IPN) gel beads were developed through a photo-cross linking reaction with mixed barium ions and calcium ions at the ratio of 5:5 with the methacrylic alginate (MA), which was a chemically conjugated alginate with methacrylic groups. The second generation of primary cartilage cells was encapsulated in the MA gel beads for three weeks. In the designated timing, HE stain, Alamar blue method and Scanning electron microscopic were used to determine the cartilage cells growth, proliferation and the cell distribution in the scaffolds, respectively. The expression of type II collagen was investigated by an immunohistochemistry assay and the glycosaminoglycan content was quantitatively evaluated with the spectrophotometry of 1, 9 dimethylene blue assay. Compared to the alginate control group, the deposition of glycosaminoglycan was significantly upregulated in IPN-MA gel beads with higher cell proliferation. The secretion of extracellular matrix and proliferation of chondrocyte in methacrylic alginate gel beads were higher than that in Alginate beads. Cells were able to attach, to grow well on the scaffolds under scanning electron microscopy. The result of immunohistochemistry staining of collagen type II was positive, confirming the maintenance of chondrocyte phenotype in methacrylic alginate gel beads. This study shows a great potential for three-dimensional culture of cartilage.

Physical training induces beneficial adaptations,but long excessive exercise may lead to severe damage to the skeletal muscles,liver,heart,kidneys and immune functions. Over the past few decades,health scholars have been searching for natural components that can prevent or improve the damage induced by hyperkinesis. The mechanisms of organ damage induced by long overtraining include immunosuppression,metabolism disorder,hormone disturbance,oxidative damage, etc. Natural poly-saccharides have interventional effects on these injuries,possibly by improving immunity,regulating metabolism and ameliorating free radical damage.

Objective To investigate the effects of fragile X mental retardation protein（FMRP）on the development and migration of cerebellar neurons in mouse model.Methods Plasmids containing FMRPmutant-EGFP or EGFP were established and transfected into the lateral ventricle of the embryo mouse.Fragile X syndrome（FXS）genotype of the mouse model was identified.Nissl staining and immunofluorescence staining were conducted to assess the changes in neuron development and migration.Results In the experimental group,Nissl staining showed that the deep cerebellar neuclei contracted and divided by white matter,and the non-polarized Purkinje cells retained in internal granular layer;while immunofluorescence staining showed that Tbr2-positive unipolar brush cells changed the migration pathway and accumulated in the ventricular zone.Conclusion Cerebellar neurons showed abnormal formation and migration with the absence of FMRP.

Objective To investigate the clinical characteristics of pulmonary hypertension(PH) in patients with chronic obstructive pulmonary disease (COPD) and study the related risk factors.Methods Patients with stable COPD enrolled in this study,undergoing examinations including full pulmonary function tests (PFT),6-minute walk distance (6MWD),Exercise Oxyhemoglobin,Saint.George's respiratory questionnaire (SGRQ) and transthoracic echocardiography.Pulmonary artery systolic pressure (sPAP) ≥ 36 mmHg(1 mmHg =0.133 kPa) was defined as PH.Results A total of 251 patients were finally evaluable in this study.The frequency of PH was 55.4％ (139/251) in patients with stable COPD.Significant differences were seen between patients with PH and without PH respectively in the following factors (mean P ＜0.05):proportion of age ≥ 60 years (69.8％ vs 57.1％),forced expiratory volume in one second (FEV1)(％ predicted) [(47.5±8.2)％ vs(61.2±10.2)％ and(49.8±7.9)％ vs(66.4±11.3)％],sPAP [(41.9 ± 9.1) mmHg vs (28.2 ± 3.2) mmHg],exercise oxyhemoglobin desaturation [(-5.5 ± 3.2) ％ vs(-2.2 ± 1.2) ％],6MWD [(316.0 ± 55.2) m vs(390.0 ±75.2) m].The following variables were negatively correlated with sPAP:6MWD (r =-0.330,P =0.003),FEV1 (％ predicted) (r =-0.210,P =0.024 and r =-0.130,P =0.012,respectively).The following variables were positively correlated with sPAP:age(r =0.560,P =0.031),exercise oxyhemoglobin desaturation ＞ 3％ (r =0.540,P =0.001).Logistic regression test has showed that age≥ 60 years,exercise oxygen desaturation ＞ 3％,FEV1 (％ predicted) ＜ 50％,6MWD ＜ 350 m were risk factors for PH in COPD.Conclusion The incidence of PH in COPD increases with age,yet the performance of lung function and the activity of endurance decrease in elder patients.Sixty years or older,exercise oxygen desaturation ＞ 3％,FEV1 (％ predicted) ＜ 50％,6MWD ＜ 350 m are risk factors of PH in COPD.Echocardiography or right heart catheterization when needed should be considered to confirm the diagnosis.
