Expression of apelin mRNA in the isolated mouse adipocytes was confirmed by Northern blot. The level of apelin mRNA increased during stage of differentiation of 3T3-L1 cells. Insulin up-regulated the apelin expression in 3T3-L1 adipocytes, suggesting that apelin expression in adipocyte may correlate with obesity, insulin resistance and hypertension.

Objective:To investigate the effectiveness of mindfulness training improving negative emotions, furthering to explore the mediating effect of the improvement of mindfulness levels for the training effects.Methods:Randomized control trail was used in this research.Ninety participants who suffered negative e-motions and resolved to alleviate stress by mindfulness training were recruited by lecture.They were randomized in-to mindfulness training group or waitlist control group,and 79 of them completed the intervention (38 in mindful-ness training group and 41 in waitlist control group).Participants in mindfulness training group received an 8-week mindfulness training,while participants in waitlist control group received no intervention.Participants were assessed with the Five Facet Mindfulness Questionnaire (FFMQ,measuring mindfulness level)and Brief Profile of Mood State (POMS,measuring emotion)before and after intervention.Results:After 8-week intervention,participants in mindfulness training group got significantly higher total scores of FFMQ compared with baseline [(125.9 ±11.9) vs.(121.2 ±12.5),P<0.01].Participants in mindfulness training group also got significantly higher total scores of POMS,and the intensity-anxiety,depression-frustration,and fatigue scores of POMS compared with baseline (Ps<0.01).There were no significant differences between posttest and baseline on any scores in waitlist control group (Ps>0.05 ).The improvement of total scores of FFMQ mediated the reduction of total scores of POMS (95%CI=-6.24--0.73),and the intensity-anxiety (95%CI=-1.65 ~-0.12),depression-frustration (95%CI=-1.63--0.14),and fatigue scores (95%CI=-1.72--0.20)of POMS caused by mindfulness training.Conclusion:Mindfulness training could improve participants'negative emotions,and the enhanced mindfulness levels caused by mindfulness training will play a very important role for the improvement of negative emotions.

Objective To investigate the relationships among perceived stress,mindfulness level,and sleep problems,and to indicate the mediating role of mindfulness level in the relationship between perceived stress and sleep problems.Methods For 179 undergraduate students,the Five Facet Mindfulness Questionnaire (FFMQ),Chinese Perceived Stress Scales (CPSS) and Athens Insomnia Scale (AIS) were used to measure.Results The scores of the scales were (120.43 ± 1 1.23) for FFMQ,(40.17 ± 6.86) for CPSS and (5.28 ± 4.04)for AIS.Pearson correlation analysis showed that perceived stress was negatively correlated to mindfulness level (r =-0.602,P =0.000) and positively correlated to sleep problems (r =0.459,P =0.000) and that there was significant negative correlation between mindfulness level and sleep problems (r =-0.427,P =0.000).Hierarchical linear modeling showed significant partial mediation of mindfulness level on the association between perceived stress and sleep problems.Conclusion Mindfulness level partly mediated the positive link between perceived stress and sleep problems.

Objective To test the effect of EPO on anemia of preterm infant. Methods Thirty preterm infants less than 35 weeks of gestational age from three different hospitals were devided ramdomly into EPO group of 16 cases and control group of 14 cases. The infants in EPO group were received rh EPO 400 IU/(kg?d) subcutaneously twice a week for 4 weeks from 7 days old, together with oral supplementation of ferrous sulfate at a dossage of 3~5 mg/(kg?d) in both groups. Hemoglobin(Hb) and reticulocytes(Ret) were measured at 42 days of age. Results The hemoglobin was higherin the EPO group[(999?29)g/L vs (905?25)]g/L, P 0.05). Conclusion The is lower EPO level in prematures and efficiency of rh EPO in the treatment of anemia of preterm infants. There is no observed substantial adverse effects.

Objective To evaluate the effect of supplementation with human milk fortifier (HMF) produced by human milk protein in low birth weight infants.Methods Eighty seven low birth weight infants undergoing neonatal intensive care were divided into 4 groups randomly,human milk +HMF 9307(enriched protein 6 g/L)and human milk;formula +HMF 9308(enriched SIgA 500 mg/L)and formula.Results The weight gain was faster in human milk+HMF 9307 group than that of human milk group(13.8 g?kg~(-1)?d~(-1).vs.9.4 g?kg~(-1)?d~(-1),P

0.05). Conclusion: RVPI and RSVPI of can be used as a measure to assess VPF and speech articulation of CP patients after operation.

Objective To report filaminopathy with novel insertion mutation in a Chinese family.Methods Total 19 patients from successive 5 generations involved in an autosomal dominant family. The detailed clinical manifestations had been described (Chinese Journal of Neurology, 2008, 41:751-755).The filamin C gene sequencing was performed in 3 patients, 5 family members without symptoms and 50 normal persons. The amplified fragments of the exon 18 in filamin C gene were cloned into pBluesripts vectors, then sequenced and identified with capillary electrophoresis. Results 18-nucleotide deletion and 6-nucleotide insertion were identified in the exon 18 of filamin C gene. The mutation caused the disturbance of the seventh immunoglobulin-like domain in filamin C, leading to the instability of dimmers of filamin C.Another 2 patients in the family had same mutation while 5 family members without symptoms and 50 normal controls were normal. Conclusion The novel nucleotide deletion-insertion in exon 18 of filamin C gene causes filaminopathy. This disease can appear in non-Nordic race.

BACKGROUND: According to up-to-date development, the best timing to repair cleft palateis at 9-12 months old after birth when the articulation does not begin to develop.However, there are many over-eight-year-old children who still suffer from unrepaired cleft palate. Therefore, it is veryimportant to adopt proper surgery for these patients to improve palate form and articulatory function. OBJECTIVE: To study the characteristics of the cleft palate in patients of over 8 years old and the effects of palate repair and posterior pharyngeal flap transplantation (PPFT) on articulation. DESIGN:A controlled study with children patients as subjects. SETTING: Department of Maxillofacial Surgery, Medical College of Stomatology, Fourth Military Medical University of Chinese PLA PARTICIPANTS: Twenty-four children patients of cleft palate who were treated in the Department of Maxillofacial Surgery ,Medical College of Stomatology, Fourth Military Medical University of Chinese PLA from January 2000 through December 2003 were enrolled in the study. Fourteen were male and ten female. Their ages varied from 8 to 20 years old (mean 13.8 years). Three cases were bilateral complete cleft palate and twelve cases were unilateral complete cleft palate. Nine were incomplete cleft palate. METHODS :Two flap palatoplasty and upper pedicle PPFT were conducted in all the patients. In thirty days after surgical treatment, the patients were asked to repeat the words of a doctor in the phonetic lab with his or her lips 10 cm away from microphone. The words of the patients were recorded and evaluated subjectively by 5 doctors specialized in pathologic phones. MAIN OUTCOME MEASURES :The palatopharynx was observed with nasopharyngoscope before and after operation. And the improvement of nasal gas leakage and enhanced rhinophonia were also evaluated. RESULTS: The repaired cleft palate was healed in the first intention in all the patients. The soft palate retreated satisfactorily and the palatopharynx was apparently closed, which created good preconditions for articulation. The patients' articulation was also improved in different degrees. All the 24 patients had the fourth grade of enhanced rhinophonia and nasal gas leakage before repairing. After palate repair and PPFT, the enhanced rhinophonia and nasal gas leakage of grade 1 was in 3 patients, grade 2 in seven, grade 3 in six and grade 4 in eight patients. CONCLUSION: The combination of palate repair and pharyngoplasty is able to improve the form of soft palate and the articulation of over-eightyear-old patients with cleft palate.

Objective To report the clinical, myopathological and genetic features in myofibrillar myopathy (MFM) with numerous cytoplasmatic-spheroid bodies. Methods Ten patients in 5 successive generations began to present progressive proximal limbs weakness at 35 to 40 years old. Additionally, 4 cases manifested diarrhea and 6 cases accompanied with cardiorespiratory symptoms. An open biopsy was performed on the proband. In addition to histological, enzymhistochemical staining and ultrastructural examination, immunohistochemical staining with antibody against tau, desmin, ubiquitin, dysferlin, dystrophin-C', dystrophin-N' and dystrophin-R were done. All the exons of the MYOT, CRYAB, DESMIN, LDB3, LMNA, SEPNI gene and the FLNC exon 48 were analysed. Results Cytoplasmatic bodies and spheroid bodies were found in the fibers. The deposited material were positive for tau, desmin, ubiquitin, dysferlin and dystrophin-R, dystrophin-C'. Electron microscope showed granular dense Z-disc material in the inclusions which were surrounded by thin filament. There was no mutation in the above exons of the 7 candidate genes. Conclusions Myofibrillar myopathy involves multiple system impairment. Cytoplasmatic and spheroid bodies contain microtubule and membrane associated protein. The disease might be induced by some unknown genetic abnormities.

Objective By simulating a high-glucose condition of peritoneal dialysis (PD)fluid,to explore the effect of high glucose on the expression of leptin and its relationship with peritoneal angiogenesis.Methods Adipocytes differentiated from 3T3-L1 were divided into high glucose group (139 mmol/l glucose) and high mannitol group.Leptin levels in supernatant collected at 0 h,12 h,24 h and 48 h were measured by ELISA.Endothelial cells (ECs) were respectively cultured with normal glouse,high glucose,high mannitol condition,supernatants of adipocyte induced by normal glouse,high glucose and high mannitol,high glucose supernatants+leptin antibody,and high mannitol supernatants + leptin antibody.Tubular structure formation and migration of ECs were detected.Results Adipocytes exposed to high glucose for 48 h produced more leptin as compared with control group,high mannitol group,12 h-high glucose group and 24 h-high glucose group (all P ＜ 0.05).Compared with ECs in normal group,ECs in high glucose had less tubular structure formation and increased migration (all P ＜ 0.01).Compared with those of ECs in high glucose,the tubular structure formation and the migration of ECs in adipocyte supernatants induced by high glucose had increased (all P ＜ 0.01),and these effects were reduced by leptin antibody (all P ＜ 0.01).Conclusion There is an up-regulation of leptin in adipocytes exposed to high glucose,which may be an alternative way to prevent peritoneal angiogenesis.
