BACKGROUND: Intramyocardial transplantation of autologous umbilical cord-derived mesenchymal stem cells for repair of myocardial tissue damage is paid increasing attention in the cardiovascular field. OBJECTIVE: Human umbilical cord mesenchymal stem cells were isolated and cultured. Passage 2 human umbilical cord mesenchymal stem cells were treated with various concentratins of 5-azacytidine (2.5, 5, 10, 20, 40, 80 μmol/L) for 24 hours . After removal of 5-azacytidine, cells were cultured for another 4 weeks. RESULTS AND CONCLUSION: Before 5-azacytidine treatment, filament-like structures or particles were not observed in the cells, but the amount of cytoplasm was less and uniform, nuclear/cytoplasm ratio was high, cells exhibited typical fusiform appearance and grew in a swirl-like manner, and nucleolus was obvious. After treatment with 5-azacytidine for 24 hours, some cells died in each group, and typical fusiform appearance turned into stick-like or column-like appearance, especial y in the 40 and 80 μmol/L 5-azacytidine groups. Reverse transcription-PCR results showed that atrial natriuretic peptide and α-skeletal actin gene expression levels were detected on human umbilical cord mesenchymal stem cells after treatment with 2.5 or 40 μmol/L 5-azacytidine for 4 weeks or with 5, 10, 20 μmol/L 5-azacytidine for 1, 2, 3 and 4 weeks. These findings suggest that 5-azacytidine-induced human umbilical cord mesenchymal stem cells express the specific gene of myocardiocytes.

Objective To investigate the value of early quantified analysis of perinatal white matter injury by cranial ultrasound gray scale measurement. MethodsThe cranial ultrasound exam was performed in 152 newborns with different gestational age0 early after their birth. These newborns were divided into two groups: 104 newborns diagnosed as white matter injury within 7 days after birth were taken as patient group; while 48 newborns who were not were taken as control group. The gray scale values in the trigone of lateral ventricle of white matter were analyzed by medical image analysis system. The newborns in patient group accepted cranial ultrasound exam at one month after birth, the grey scale value and cyst in the white matter were recorded. Three to six months old, the cranial ultrasound exam was repeated to record the change of white matter volume, morphology of lateral ventricle and change of the cysts. When they were 1.5 to 2 years old, the neurological function were quantitatively evaluated with Gesell score, and the results were classified as normal and abnormal.The relationships between gray scale value and neuro-developmental outcome were analyzed with receiver operating characteristic curve.Results During neonatal period, the average gray scale values in severely injured group was 131.72±2.40, higher than that of mildly injured group (116.61±2.48), and which in mildly injury group was higher than that in control group (100.50±1.66) (q=4. 521 and 4. 492, P＜0. 05). It was showed by receiver operating characteristic curve that gray scale value ＞114.37 could help to diagnose white matter injury, with the sensitivity of 0. 721 and the specificity of 0. 854; gray scale value ＞119.80 could help to diagnose severe white matter injury,with the sensitivity of 0. 716 and the specificity of 0. 776.As the gray scale value increased, the incidence of white matter volume decreased and the enlargement of lateral ventricle in the later period of injury increased. Patients with gray scale value ＞ 130 tended to suffer from leucomalacia. During neonatal period, the incidence of abnormal neurodevelopment before 2 years old was 5.0％ in patients with gray scale value ＜ 110, while it was 27.8 ％ in the patients with gray scale value between 110 and 120, 47.8％ in the patients with gray scale value ＞ 120.Conclusions Quantified analysis of ultrasound gray scale value might be promising in early diagnosis of perinatal white matter injury through early judgement of the outcomes of white matter injury and forward neurodevelopment.

OBJECTIVETo explain the essence of pungent-hot herb property express according to in vivo and in vitro studies on its effect on calmodulin on the base of the observation of the adjustment in hypothalamic-pituitary-gonad axis functions of Aconiti Lateralis Radix Praeparata, Curculiginis Rhizoma, Cinnamomi Cortex and bitter-cold herb Phellodendri Chinensis Cortex in rats under the state of yang deficiency.

METHODThe yang-deficient model was duplicated by intramuscularly injecting hydrocortisone sodium succinate powder injection. After the intervention with Aconiti Lateralis Radix Praeparata, Curculiginis Rhizoma, Cinnamomi Cortex and bitter-cold herb Phellodendri Chinensis Cortex for seven days, TSH, T3, T4, 17-OHCS, COR, T, E2 of hypothalamus-pituitary-target gland axis and other relevant indexes were detected. The calmodulin expression in livers and L02 cells cultured in vitro was detected by using Western blot.

RESULTPungent-hot herbs Aconiti Lateralis Radix Praeparata, Curculiginis Rhizoma, Cinnamomi Cortex can significantly correct indicators of hypothalamic-pituitary-gonad axis and calmodulin, whereas the bitter-cold herb Phellodendri Chinensis Cortex showed no obvious effect.

CONCLUSIONThe pungent-hot herb property expression may be closely related to calmodulin.

OBJECTIVEPrevious studies suggested that a number of obstetrical factors were associated with small-for-gestational-age (SGA) infant. However, it remained uncertain which obstetrical factors might increase the risk of SGA due to limitations of small sample size and poor study designs in the previous studies in China. We assessed the association of a few maternal factors, such as pregnancy-induced hypertension (PIH), oligohydramnios, infectious diseases of reproductive system, abnormal conditions of placenta or umbilical cord, previous adverse pregnancy outcomes, hysteromyoma and maternal education level, and the risk of SGA.

METHODSWe examined the association in a case-control study, in which the SGA group included all of 834 (443 males and 391 females) singleton alive SGA deliveries in our hospital during January 2000 to October 2004. 2502 (1329 males and 1173 females) appropriate-for-gestational-age (AGA) infants (1:3, SGA/AGA) matched by gender- and gestational-age-stratified frequencies of SGA were randomly selected for controls from infants with sex-specific birthweight for gestational age ranged between 10th-90th percentiles. Odds ratios (95% confidence interval, 95% CI) of these factors for SGA were calculated in univariate and multivariate analyses. The maternal risk factors were diagnosed by the relevant criteria used in China. SGA was defined as sex-specific birthweight for gestational age that was less than 10th percentile cut-off of fetal growth reference of singleton alive infants delivered in our hospital during that period.

RESULTSResults from univariate analysis showed that PIH, oligohydramnios, history of adverse pregnancy outcome, poor maternal education and viral hepatitis were significantly associated with SGA. The odds ratios (95% CI) of these five factors for SGA were 3.95(2.79-5.60), 2.94(2.27-3.80), 7.01(3.87-12.70), 3.62(2.92-4.49) and 0.52(0.32-0.87), respectively. In the multivariate logistic analysis, a similar result was shown. The ratios of maternal PIH, oligohydramnios, history of adverse pregnancy outcome and viral hepatitis in the SGA group were 4.00(2.81-5.71), 2.95 (2.27-3.83), 5.95 (3.05-10.64), 0.50(0.30-0.84) folds of those in the AGA group; the ratio of maternal low formal education (< or = 9 years) in the SGA group was 3.46(2.75-4.24) times of the AGA group.

CONCLUSIONPIH, oligohydramnios, poor maternal education and a history of adverse pregnancy outcome were significantly associated with an increased risk of SGA while viral hepatitis might be associated with a decreased risk of SGA.

Objective To assess the effect and feasibility of group reminiscence therapy on depression in the elderly.Methods We searched the Cochrane Central Register of Controlled Trials (-2013),Medline (1982-2013),Embase (1974 2013),AMED (-2013),CINAHL(-2013),CMB (1994-2013),VIP,CNKI and Wanfang to collect the randomized controlled trials (RCTs) in which the group reminiscence therapy was used to treat depression in elderly patients.The studies were selected according to the inclusion and exclusion criteria by two reviewers,and the quality of included studies was evaluated according to Cochrane Handbook and performed meta analyses by using the Cochrane Collaboration's RevMan 5.2 software.Results A total of 10 RCTs involving 944 patients were included.The results of meta-analysis showed that as compared with conventional treatment,group reminiscence therapy on the basis of conventional treatment was more effective in decreasing depression score [MD=-4.86,95 ％ C I(-5.10,-4.65)].Compared with psychological counseling,group reminiscence therapy had more effect on decreasing depression score [MD=-9.34,95％ CI (-10.77,-7.91)].There was no significant difference in the dropout rate between group reminiscence therapy and other control treatments [RR=1.22,95％ CI (0.79-1.88)].The descriptive analysis showed that group reminiscence therapy was effective in alleviating the symptoms of depression.Conclusions Group reminiscence therapy can improve the symptoms of depression in elderly patients and conforms to the principle of economic benefit.However,the results should be interpreted with caution because of the low quality of the included studies.

Objective To assess the status and severity of bone disease in patients with multiple myeloma (MM) by using chest computerized tomography (CT) and the relationship between clinical prognostic parameters and bone disease.Methods All 46 newly diagnosed MM in-patients received both imaging tests of chest CT and plain X ray.An experienced radiologist reviewed all the imaging data.Clinical laboratory parameters,stages of Durie-Salmon (DS) and International Staging System (ISS) were evaluated.Five cytogenetic abnormalities of bone marrow myeloma cells were tested by fluorescence in situ hybridization (FISH).Results The sensitivity of CT and X ray to determine pathological fractures was comparable,the positive rates of which were 41.3％ (19/46) and 30.4％ (14/46) respectively (P =0.29).Nevertheless,the positive rate of osteolytic lesions ascertained by CT was significantly higher than that by X ray (P ＜ 0.001),60.9％ (28/46) vs 13.0％ (6/46) with diameter 5-10 mm and 50.0％ (23/46) vs 10.9％ (5/ 46) with diameter more than 10 mm.Osteolytic lesion numbers found by CT were more than those by X ray [5(0-21) vs0(0-4) lesions with diameter5-10 mm (P＜0.001),2(0-14) vs0(0-2) lesions with diameter more than 10 mm (P ＜ 0.001),respectively].Patients with positive osteolytic lesions had higher percentage of RB1 gene deletion[46.7％ (14/30) vs 18.8％ (3/16),P ＜0.001],D13s319 deletion [43.3％ (13/30) vs 18.8％ (3/16),P ＜0.001] and high risk cytogenetic abnormalities[50.0％ (15/30) vs 25.0％ (4/16),P ＜ 0.001].Conclusions Chest CT is more sensitive than plain X ray in detecting osteolytic myeloma bone disease.Osteolysis determined by CT is relevant to clinical DS stages and risk stratification of cytogenetic abnormalities.

Objective To explore the clinical features,diagnosi s and prognosis of incontinentia pigmenti.Methods Analyzing and summarizing the clinical characteristic, diagnosis and prognosis of neonatal incontinentia pigmenti in 6 neonatal infants that were hospita- lized in our department during the period from January 1 998 to December 2003 were studied,and some relevant literature were reviewed. Results 1.Three of 6 infants were male which was unusual;2.Four infants had typical skin lesions at birth and 1 case at 6 days old.Four cases had typical 3 stages o f skin lesions including the erythematous and vesicular inflammatory stage,verr ucous lesions and hyperkeratosis stage,macular hyperpigmentation stage,but the re was overlap;3.Four infants were complicated by central nervous system involv ement (two cases presented mental retardation,2 infants were temporary damage). Two cases were complicated by ocular manifestations ( one case had optical nerve atrophy and blind in left eye,the other had severe bilateral retinal lesions); 4.On specific examination 5 infants were diagnosed by skin biopsy.Gene analysis was made in 1 case,but we didn′t find the mutations of NEMO. Conclusions Incontinentia pigmenti is a rare X-linked dominant multisystem disease.It may be misdiagnosed in the initial stages.Except typical clinical features,skin biops y and gene analysis are main evidence for diagnosis.Early detection and interven tion are important for prognosis.
