目的 对胎儿中枢神经系统发育异常的患者进行回顾性分析,探讨处理及预后。方法 收集2016—2018年在本院因胎儿畸形就诊的275例患者行病案追踪和电话随访。结果 275例产前彩超提示胎儿神经系统异常中,侧脑室增宽比列最高,112例(40.73%,112/275)。其他类型的异常包括后颅窝池增宽、脉络丛囊肿、胼胝体发育不全、Dandy-Walker综合征、脊柱裂、小脑病变、蛛网膜囊肿、室管膜囊肿、复杂性畸形等,共163 例(59.27%,163/275)。112例胎儿侧脑室增宽病例中,产前或产后消退 80例(71.43%,80/112),引产25例(22.32%,25/112),其引产病例中15例(60%,15/25)为重度侧脑室增宽。结论 胎儿侧脑室增宽是一动态发展过程,产前超声发现轻中度胎儿侧脑室增宽,不用盲目引产,可定期追踪观察。对严重侧脑室增宽,或存在其他明显脑结构异常的胎儿,致残率和致死率很高,一旦发现,应给予高度重视,综合评估以明确诊断、评估预后,告知患者及家属保留胎儿可能存在的风险及近远期并发症,充分沟通,减少严重畸形儿的出生。

目的 探讨高频经颅磁刺激治疗对 PSD 伴失眠患者的抑郁情绪及睡眠质量的疗效。方法 对63例PSD患者随机分为联合组32例(10Hz高频rTMS+艾司西酞普兰)及药物组31例(艾司西酞普兰+假刺激),每周5次,共治疗4周。于治疗前及治疗后4周末分别对两组患者进行HAMD、PSQI评分及多导睡眠监测。。结果 rTMS 治疗前,2组HAMD、PSQI评分及睡眠参数比较均无差异;治疗后第4周末,两组HAMD评分、PSQI评分、总睡眠时间、睡眠效率及快眼动睡眠期比例均较治疗前改善;研究组HAMD评分下降幅度较对照组明显,而PSQI评分下降幅度及相关睡眠参数改善无差异。结论 高频rTMS治疗对PSD的抑郁症状疗效更明显,而对睡眠质量及睡眠结构的改善则与药物治疗疗效相当。

Objective To investigate the effect of high frequency transcranial magnetic stimulation on depression and sleep quality in poststroke depression patients with insomnia. Methods 63 patients with PSD were randomly divided into observation group (n=32)and control group (n=31). Both groups were treated by 10~20 mg escitalopram citalopram for 4 weeks. The patients in observation group also accepted 10 Hz rTMS 10 times (i.e., as a course), while the patients in control group were treated by sham stimulation. At the baseline and 4th week, the 17-item Hamilton depression scale (17-HAMD), Pittsburgh Sleep Quality Index (PSQI)and polysomnography (PSG)were evaluated. Results The sleep parameters, PSQI scores and HAMD scores among two groups had no significant difference at baseline. After 4 weeks treatment, the HAMD score, PSQI score, total sleep duration, sleep efficiency and proportion of rapid eye movement sleep in both groups were improved compared with those before treatment. The descend range of HAMD score in observation group was larger than that in control group (t=2.590,P=0.012), while the descend range of PSQI scores(t=0.897,P=0.373)and the change of the sleep parameters in the two group had no obvious difference. Conclusion High frequency rTMS has better curative effect than antidepressant therapy on depressive symptoms of PSD,while there was no difference on the effect to improve the sleep quality and sleep structure of PSD between these two treatments.

目的 探讨高脂血症大鼠模型前后血液中氨基酸代谢谱的变化,寻找高脂血症大鼠血液中氨基酸代谢标志物。方法 将SD大鼠随机分为正常对照组、模型组,连续灌胃给药4周后收集大鼠血液,测定各组大鼠血清中TG、TC、HDL-C、LDL-C含量,并运用超高效液相色谱-四极杆-飞行时间质谱(UPLC-Q-TOF-MS/MS)法测定血清中氨基酸代谢谱,利用统计学分析研究不同组动物间的氨基酸代谢的差异。结果 与正常对照组比较,模型组TG、TC、LDL-C含量升高,HDL-C含量降低,高脂血症大鼠模型建模成功;与正常对照组比较,模型组蛋氨酸、苯丙氨酸、脯氨酸、苏氨酸、缬氨酸、甘氨酸等6种氨基酸发生明显改变(P<0.05)。结论 高脂血症大鼠存在氨基酸代谢的紊乱,其中蛋氨酸、苯丙氨酸、脯氨酸、苏氨酸、缬氨酸、甘氨酸等6种氨基酸为其潜在的生物标志物。

Objective To investigate the amino acid metabolism profiles changes in the serum of SD rats, and identify the potential biomarkers. Methods SD rats were divided into normal group and model group. The contents of TG, TC, HDL-C, and LDL-C in the serum of each group were measured, after 4 weeks of continuous intragastric administration. Ultra performance liquid chromatography coupled with electrospray time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MS/MS)was used to determine amino acid metabolism profile in serum, and statistical analysis was applied to determine metabolic differences among different groups of rats. Results As compared with normal group, TG, TC, LDL-C were increased and HDL-C was decreased in model group, hyperlipidemia rat model successfully modeled. As compared with normal group, methionine, phenylalanine, proline, threonine, valine, glycine in the amino acid metabolic profiling were decreased in model group (P＜0.05). Conclusion Hyperlipidemia rats have disorders of amino acid metabolism, of which methionine, phenylalanine, proline, threonine, valine, and glycine are potential biomarkers.

目的 探讨新生儿高促甲状腺素血症转归与先天性甲状腺功能减低的相关性。方法 选择2014年4月—2015年4月在本院新生儿疾病筛查中心筛查并诊断为高促甲状腺激素血症的患儿120例,期间密切监测甲状腺功能指标变化。结果 将非治疗组所有患儿按照入组该实验后首次抽取静脉血TSH检测水平分为3组:5.5~10.0 mU/L(20例)、10.1~15.0 mU/L(10例)、＞15.0 mU/L (8例)。非治疗组患儿第2次随访结果显示5.5~10.0 mU/L组所有患儿TSH水平<10.0 mU/L;10.1~15.0 mU/L组有1例患儿TSH水平＞10.0 mU/L,FT4水平在正常值上限;＞15.0 mU/L组有3例患儿 TSH水平＞10.0 mU/L,差异有统计学意义(P< 0.05),FT4水平在正常均值左右,差异没有统计学意义(P＞ 0.05),＞15.0 mU/L组3例患儿给予左旋甲状素钠治疗。治疗组有2例患儿分别在治疗15天和23天后出现医源性甲状腺功能亢进,停药和酌减药量后TSH、FT4水平均恢复正常。两组患者随访结束后TSH、TF4均恢复至正常水平。结论 大多数新生儿高促甲状腺素血症会随着年龄的增长恢复正常,而仅仅有少部分患儿会持续出现甲状腺功能异常,应积极随访;新生儿只有当TSH 基础值＞15.00 mU/L时才需要采用左旋甲状素钠替代治疗,并且严格随访甲状腺功能,避免过度治疗。

目的 分析ABCB1基因G2677T、C3435T位点在我国汉族血脂异常人群的分布特征;探讨ABCB1基因G2677T和C3435T多态性与阿托伐他汀降脂疗效之间的关系。方法 依据中国成人血脂异常防治指南判断标准,在中国汉族人群中收集205例受试者,抽取其外周血液样本,利用聚合酶链式反应-限制性片段长度多态分析(PCR-RFLP)技术对受试者ABCB1进行基因分型,同时在阿托伐他汀治疗3个月前后检测总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)血脂水平,将205例患者治疗后4项指标恢复正常分为A组,治疗后4项指标仍有一项及一项以上异常分为B组,来分析G2677T和C3435T基因多态性与阿托伐他汀降脂疗效的关系,以及G2677T和C3435T等位基因的分布特征。结果 205例患者中G2677T位点GG型、GT型、TT型基因频率分别为19.51%、42.44%、38.05%;C3435T位点CC型、CT型、TT型基因频率分别为34.63%、49.76%、15.61%。G2677T位点A组与B组等位基因突变率为58.46%与60.67%,A组GG型、GT型、TT型基因频率分别为23.08%、36.92%、40.00%,B组GG型、GT型、TT型基因频率分别为13.33%、52.00%、34.67%;C3435T位点A组与B组等位基因突变率为40.77%和40.00%,A组CC型、CT型、TT型基因频率分别为34.62%、 49.23%、16.15%,B组CC型、CT型、TT型基因频率分别为34.67%、50.67%、14.66%;ABCB1 基因G2677T、C3435T位点基因型在A组和B组中分布相同,无差异(P＞0.05)。205例患者中,用药前ABCB1基因G2677T位点TT型血浆TC、LDL-C水平高于GT型(P＜0.05)。用药后ABCB1基因G2677T位点GT型血浆TC、HDL-C、LDL-C水平低于GG型与TT型(P＜0.05);用药后ABCB1基因C3435T位点TT型血浆TC水平低于CC与CT型(P＜0.05),而CC型血浆LDL-C水平高于TT型(P＜0.05)。结论 ABCB1基因G2677T、C3435T位点多态性与血浆血脂水平有关,但ABCB1基因G2677T、C3435T位点多态性可能与阿托伐他汀3个月降脂疗效无关。

目的 通过比较炎症性肠病(IBD)患者的血脂水平,探讨炎症性肠病疾病活动程度与血脂的相关性。方法 收集2013年1月—2018年5月在南方医科大学附属南海医院住院的159例IBD患者和159例健康对照为研究对象,检测分析两组的血浆TG、TC、LDL-C、HDL-C、脂蛋白a、白蛋白和超敏C反应蛋白(hCRP)水平差异,分析IBD患者疾病活动程度与血脂异常的关系。结果 与对照组比较,IBD患者的TG、TC、LDL-C、HDL-C和白蛋白均下降,但脂蛋白a升高(P＜0.05),且CD组的TC、LDL-C、HDL-C、白蛋白均较UC组更低(P＜0.05)。TC、LDL-C、HDL-C等胆固醇水平随IBD疾病活动程度加重而逐渐下降,且与hCPR呈负相关,脂蛋白a与hCRP呈正相关性,但未见TG水平与疾病活动相关。结论 IBD患者的胆固醇水平下降,脂蛋白a升高,CD患者更明显,胆固醇水平随IBD病情加重逐渐下降,且与hCRP呈负相关。

Objective To explore the correlations between disease activity of inflammatory bowel disease(IBD) and lipid profiles levels by compare the levels of plasma lipids in patients with IBD. Methods A total of 159 IBD patients admitted to Nanhai Hospital of Southern Medical University from January 2013 to May 2018 were included in the study and the clinical data were collected. There were 159 healthy people recruited in the control group. The differences of plasma levels of triglycerides(TG), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), lipoprotein(a), albumin and high-sensitivity C-reactive protein(hCRP) between these two groups were analyzed respectively. The relationships between lipids levels and the severity of IBD were analyzed. Results Plasma levels of TG,TC,LDL-C,HDL-C and albumin were lower in IBD group than those in control group,but lipoprotein(a) was higher than control group(P＜0.05). The levels of TC,LDL-C,HDL-C and albumin were lower in CD patients compared to those of UC(P＜0.05). Plasma levels of TC,LDL-C,HDL-C gradually decreased with the severity of IBD. TC,LDL-C,HDL-C values were negatively correlated with hCRP levels in IBD patients. And lipoprotein(a) values was positively correlated with hCRP levels in IBD patient. However, there was no association between TG levels and the severity of IBD. Conclusion TG、TC、LDL-C、HDL-C levels are decreased and lipoprotein(a) is increased in IBD patients, especially CD patients, compared with healthy controls. Moreover, the cholesterol levels are negatively associated with more severe disease activity.

雄激素性脱发是一种人群中常见的损容性疾病,其发病与多种因素有关,而遗传因素在发病率中具较大的影响。低能量激光疗法(Low-Level Laser Therapy)是近年来用于治疗雄激素性脱发的光疗技术。低能量激光是一种低能量,短波长的激光,因早期研究发现其具有促进毛发生长的作用而被用于研究治疗雄激素性脱发(AGA)。在低功率激光疗法中,通过使用低能量激光照射毛囊,使毛囊炎性反应得以减轻,同时促进细胞新陈代谢,从而使休止期毛囊复苏,达到促进毛发生长的作用。本文通过对低能量激光疗法治疗雄激素性脱发的机制及效果进行论述,并讨论局部治疗、系统治疗等其他方法联合低功率激光在AGA治疗中的研究进展。

Androgenetic alopecia is a common and ashamed disease in the human population. Its incidence is related to a variety of factors, and the gene have a greater impact on the incidence. Low-level laser therapy LLLT is a phototherapy technique for the treatment of androgenetic alopecia in recent years. Low-level laser means low-energy, short-wave length that have been used for research and treatment of androgenetic alopecia because of the early discovery which is promoting hair growth. In LLLT, the laser irradiates hair follicles, so that reduces the folliculitis, while promoting cell metabolism.From this, the dormant hair follicles resume growth. This article discusses the mechanism and effect of low-level laser therapy for the treatment of androgenetic alopecia, and further discusses the advancement of topical treatment, systemic treatment, and other methods which combined with low-level laser in the treatment of AGA.
