Objective To investigate the distribution characteristics and clinical features of familial aggregation hemangioma to improve the level of the diagnosis and treatment.Methods Total 1202 cases of vascular disease were treated in this department from June 2006 to June 2011.The clinical data and family distribution characteristics in 36 cases of familial aggregation hemangioma were analyzed and their effects of laser treatment were evaluated.Results 36 cases were familial aggregation hemangioma,whose incidence was 2.99 ％ in 1202 cases of vascular disease cutis; and the ratio of male to female was 1 ∶ 1.There were 9 cases of parents suffering from hemangioma.But the incidenceof the next generation suffering from vascular disease was 28.5 ％.Among these 36 cases of familial aggregation hemangioma,33 cases underwent the long pulse 1064 nm Nd ∶ YAG laser and optimized pulse light combination therapy.The effective rate was 100 ％.Conclusions There may be a genetic predisposition in hemangioma.The application of long pulse 1064 nm Nd ∶ YAG laser and optimized pulsed light treatment to hemangioma cutis can obtain satisfactory results.The intervention should be taken in early stage.

Objective To explore the effects of willed movement on neurological performance and the extracellular signal-regulated kinase (ERK) and cAMP response element binding protein (CREB) pathway in rats following focal cerebral ischemia.Methods Reversible middle cerebral artery occlusion was induced in 144 male SpragueDawley rats using intraluminal sutures,and they were randomly divided into a control group,a swimming exercise group,an environment modification group,and a willed movement group.The observation time points were at 7,15 and 30 days after reperfusion.A behavioral test was performed to evaluate any neurological deficiency.Reverse transcription PCR (RT-PCR) and immunofluorescence were used to detect the ERK and CREB responses in terms of mRNA and phosphorylated ERK (pERK) and phosphorylated CREB (pCREB) protein in the peri-ischemic brain tissue.Results The climbing frequency of the willed movement group was significantly higher than that of the environment modification group.Three days after reperfusion the neurological deficit scores of all groups began to decrease,and that of the willed movement group had decreased significantly more than in the other three groups at all time points.ERK/CREB mRNA and pERK and pCREB protein expression were dramatically up-regulated in the willed movement group at 7,15 and 30 days after reperfusion,significantly more than in the other three groups.Conclusions Willed movement may promote motor recovery by up-regulating and activating the ERK/CREB pathway following focal cerebral ischemia.

Depression disorder(DD)is one of the major mental health problems worldwide,and special nutrients such as amino acids,vitamins,fatty acids,probiotics,etc.can affect the emotional state and disease prognosis of DD patients.Amino acids such as tryptophan and S-adenosylmethionine have been shown to improve stress levels in DD patients through various mechanisms,including vitamin B and vitamin C,while unsaturated fatty acids and probiotics have also been shown to have the same effect.This article reviews the mechanisms by which these nutrients improve DD,with the aim of providing new clues for treatment of DD.

Objective:To investigate the indications for prenatal diagnosis and pregnancy outcomes of fetal Turner syndrome (TS) with different karyotypes.Methods:Clinical data of TS cases diagnosed by fetal karyotyping in the Prenatal Diagnostic Center of Guangzhou Women and Children′s Medical Center from January 1, 2010, to June 30, 2021, were analyzed retrospectively. According to the karyotyping results, these cases were divided into two groups: monosomy X (45,X) and non-monosomy X groups (including karyotypes of mosaic monosomy X, isochromosome X, X deletion, X rearrangement, pseudodicentric X, and mosaicism with Y or Y deletion). Chi-square test was used to compare the detection rate, indications for prenatal diagnosis, and pregnancy outcomes of the two groups, and the Bonferroni test was conducted for further pairwise comparisons between the subgroups. The Chi-square test (or Fisher's exact test) was used to compare the abnormal ultrasound signs. Mann-Whitney U test was used to compare the nuchal translucency (NT) thickness of the two groups. Results:(1) Invasive prenatal diagnosis was performed on 27 981 pregnancies, and 205 (0.73%) of them were diagnosed with TS, including 135 cases of monosomy X and 70 cases of non-monosomy X (44 with numerical sex chromosome abnormalities, and 26 with structural sex chromosome abnormalities). (2) Out of the 205 pregnancies, 164 (80.0%) had one indication for prenatal diagnosis, and 41 (20.0%) had multiple indications. The detection rate of fetal ultrasonographic abnormalities [85.2% (115/135)] in monosomy X cases was significantly higher than that of three other indications [positive serological screening for Down's syndrome: 67.3% (35/52); positive non-invasive prenatal testing (NIPT) for sex chromosome abnormality: 60.0% (15/25); and other indications (advanced maternal age, adverse pregnancy history and thalassemia genes carried by both parents): 5.2% (7/135); all P<0.05], and also higher than the figure in non-monosomy X cases [25.7% (18/70), χ 2=71.55, P<0.001]. In non-monosomy X cases, the detection rates of TS among cases with high-risk results from serological screening for Down's syndrome and NIPT for sex chromosome abnormality [54.7% (29/53) and 68.3% (28/41)] were higher than those of the other two indications [fetal ultrasonographic abnormalities: 25.7% (18/70), other indications: 14.3% (10/70); all P<0.05]. (3) Of the 133 pregnancies with fetal ultrasonographic abnormalities as the indication, 65 (48.9%) had one abnormal ultrasound sign, and 68 (51.1%) had multiple signs. Among the 95 cases with ultrasound abnormalities in the first trimester and 38 cases in the second or third trimester, the incidence of cystic hygroma and hydrops was significantly higher in monosomy X cases than in non-monosomy X cases [in the first trimester: 71.8% (61/85) vs 1/10, 34.1% (29/85) vs 0/10; in the second or third trimester: 73.3% (22/30) vs 0/8, 50.0% (15/30) vs 0/8; Fisher's exact test, all P<0.05]. NT thickness in monosomy X cases was greater than that of non-monosomy X cases [7.5 mm (1.0-17.4 mm) vs 1.7 mm (0.8-9.5 mm), Z=－5.25, P<0.001]. (4) Among the 72 pregnancies with indications other than ultrasound abnormalities, 68 underwent Down's syndrome screening and 61 underwent NIPT. The detection rates among the cases with positive results in Down's syndrome screening, NIPT for a sex chromosome abnormality, and other indications (advanced maternal age, adverse pregnancy history, and thalassemia genes carried by both parents) were 54.4% (37/68), 59.0% (36/61) and 22.2% (16/72), respectively ( χ 2=22.40, P<0.001). The detection rates of the cases with high-risk results from Down's syndrome screening and NIPT for sex chromosome abnormality were higher than that of the cases with other indications ( χ 2=18.77 and 15.40, both P<0.001). Of the 72 pregnancies, 19 (26.4%) were monosomy X and 53 (73.6%) were non-monosomy X, including 42 (58.3%) with chromosomal mosaicism. (5) Among the 205 cases of TS, 185 were successfully followed up (123 were monosomy X and 62 were non-monosomy X). There was one live birth in monosomy X cases (0.8%, 1/123) and 17 in non-monosomy X cases (27.4%, 17/62), and the difference was statistically significant ( χ2=33.22, P<0.001). Sixty-three TS cases with normal ultrasound findings were followed up (18 were monosomy X and 45 were non-monosomy X). In these cases, all 18 pregnancies with monosomy X and 32 (71.1%, 32/45) with non-monosomy X were terminated and the other 13 (28.9%, 13/45) cases of non-monosomy X were delivered. Of the 18 live births, one (non-monosomy X) was delivered at 36 weeks of gestation and the rest were born at term. Eleven cases of them were followed up. The height of one child with monosomy X was lower than the average height of children of the same age and sex by more than 2 standard deviations (－2 SD). The height of 10 children with non-monosomy X were between－1 SD and +3 SD among the children of the same age and gender. The mental and motor development were good in the 11 cases, and no other structural abnormalities were observed. The remaining seven cases refused to be followed up. Conclusions:Ultrasonographic abnormalities are the main indications of fetal TS with monosomy X, while positive Down's syndrome screening and positive NIPT for sex chromosome abnormality are indicators of non-monosomy X. The termination rate for pregnancies with monosomy X is higher than that for non-monosomy X.

Objective:To investigate the antibacterial efficacy of allicin effective component,dially trisulfide(DATS),on the biofilms of Enterococcus faecalis(E.faecalis)in vitro.Methods:60 healthy single root canal permanent teeth were selected.After cleaning and autoclaving,15 teeth without infection were used in the negative control group,45 teeth were contaminated by E.faecalis and incubated for 28 days as the infection models and devided into 3 groups(n=15)as below:DATS group,Calcium hydroxide group and positive(without antibacteria treatment)control group.The minial inhibition concentration(MIC)and minial bactericidal concentrition(MBC)of DATS on E.feacalis were studied with doubling diluting method.At the day 1,2 and 7 of the exprement,the 4 mg of root canal in-ner dentin powder,5 specimens of each group were sespectively transfered into sterile bottle containing 2 mL BHI broth and cultured at 37 ℃ 5％CO2 for 72 h,the turbitity of the upper layer of liquid of the culture was measured.Results:MIC and MBC(μg/mL)of DATS to E.feacalis was 2 560 and 5 120 repsectively.At the first day,turbidity in the DATS group was the lowest(P＜0.05).At the third day,turbidity showed no difference between DATS group and negative control group(P=0.454).At the 7th day,between calcium hydroxide and the negative control group,P＜0.05.Conclusion:DATS may suppress E.faecalis in the biofilm in vitro.

ObjectiveTo obtain the prevalence of sarcopenia in middle-aged and elderly people in Urumqi based on the 2020 updated based on the 2020 updated Consensus Report 2019 of Asian Working Group for Sarcopenia （AWGS2019）， and to further explore the association between sarcopenia and metabolic syndrome （MS）. MethodsA total of 1 438 middle-aged and elderly people （aged≥50 years） in Urumqi from July 2018 to January 2019 were selected as the research subjects. Data were collected by questionnaire survey， physical examination and laboratory test. Skeletal muscle mass，grip strength and 4 m walking speed were used to represent muscle mass， muscle strength and body function， respectively. Bioelectrical impedance analysis （BIA） was used to measure human body components. Based on the diagnostic criteria of sarcopenia recommended by AWGS2019， the prevalence of sarcopenia in people over 50 years old was obtained. Multivariate logistic regression model was used to explore the correlation between sarcopenia and MS in middle-aged and elderly people of different genders. ResultsThere were 194 patients with sarcopenia， with a prevalence of 13.49%. The prevalence was 15.56% in males and 12.12% in females. There was no significant difference in the prevalence of MS between male sarcopenia group （40.45%） and non-sarcopenia group （38.92%）， while the prevalence of MS in female sarcopenia group （39.04%） was higher than that in non-sarcopenia group （27.56%）. Multivariate logistic regression analysis showed that sarcopenia was a related factor of MS. Compared with non-sarcopenia， the risk of MS in male sarcopenia group was higher （OR=2.11，95%CI： 1.15‒3.88 ）. ConclusionSarcopenia increases the risk of MS in middle-aged and elderly people， with a greater risk in men. Fully understanding of sarcopenia is helpful to early identify high-risk groups of MS and prevent the occurrence of MS.

ObjectiveTo explore the correlation between skeletal muscle mass and metabolic syndrome （MS） disease risk among middle-aged and elderly community residents in Urumqi， and to provide a theoretical basis for understanding the relationship between skeletal muscle mass and MS among middle-aged and elderly community residents in China. MethodsA total of 1 438 community residents ≥ 50 years old were selected as the research subjects from July 2018 to January 2019 in Urumqi. They were selected from a multi-ethnic natural population cohort in Xinjiang. Data were collected through questionnaires， physical examination， bioelectrical impedance analysis （BIA）， laboratory tests， etc. Skeletal muscle mass was evaluated using the limb skeletal muscle mass index （SMI） corrected for body weight； MS was defined as it at least includes three of the following： abdominal obesity， hypertension， hyperglycemia， high triglycerides and low high-density lipoprotein cholesterol. SMI was divided into four quantile arrays of Q₁‒Q₄. Trend χ² test was applied to explore whether there was a correlation between SMI changes and MS. A multivariate logistic regression model was used to analyze whether there is a difference in the risk of MS between the higher SMI group （Q₂， Q₃， Q₄） and the reference group Q₁. ResultA total of 560 MS patients were detected in this study， with a prevalence rate of 38.94%. Among them， the prevalence rate of MS was 39.16% in males and 38.80% in females. The increase in male SMI grading level is not correlated with the prevalence of MS （trend P>0.05）； After adjusting for confounding factors （model 4）， the increase in SMI was still not related to the prevalence of MS （P_trend=0.995）. There was no statistical difference in the risk of MS between the lowest quartile group Q₁ and the highest quartile group Q₄ （OR=1.01， 95%CI： 0.69‒1.78）. The prevalence of MS in women gradually decreased with the increase of SMI grading level （P_trend<0.001）； After adjusting for confounding factors （model 4）， there was still a correlation between the increase of SMI and the prevalence of MS （P_trend=0.005）. With the lowest quartile of SMI Q₁ as the reference group， the risk of MS in Q₂ （OR=0.63， 95%CI： 0.40‒1.00）， Q₃ （OR=0.56， 95%CI： 0.34‒0.94）， Q₄ （OR=0.42， 95%CI： 0.23‒0.76） decreased. ConclusionAn increase in skeletal muscle mass may be beneficial for preventing MS， especially among middle-aged and elderly female residents. Considering the intensification of aging in China and the close relationship between MS and related comorbidities， managing skeletal muscle mass may contribute to potential MS prevention.
