Objective To investigate the relationship between the CYP2E1 ＊ c1/ ＊ c2 polymorphism and alcohol use disorders, and the potential influence of the CYP2E1 ＊ c1/ ＊ c2 polymorphism on the severity and dimensions of alcohol use disorders in Tibetan. Methods Three hundred and forty Tibetans with Alcohol Use Disorders Identification Test （AUDIT） score ≥ 10 and another 315 matched control subjects with AUDIT score ≤5 were enrolled. The CYP2E1 ＊ c1/ ＊ c2 polymorphism was determined by the standard PCR-RFLP method. Results The frequency of the CYP2E1 ＊ c2 allele in subjects with alcohol use disorders （16. 2% ） was significantly higher than that of the controls （10.8%）, with a P value of 0.005 and OR value of 1.60 （95% CI： 1.15-2.21）. There was also a significant difference in genotype frequencies between the 2 groups （ χ~2 = 8.75 , P = 0.01 ）. Subjects with alcohol use disorders had higher frequencies of genotypes with at least one copy of allele c2 （28.5% vs. 18.7% ; χ~2 =8.65, P=0.003; OR =1.73） than the control group. The associ- ation of CYP2E1 ＊ c2 allele with alcohol use disorders was much stronger in males than in females, with a male OR value of 2.30. CYP2E1 ＊ c2 allele was associated with increased alcohol consumption and alcohol use disorders in males. Conclusion There is the positive association among CYP2E1 ＊ c2 allele, alcohol use disorders, and the amount of alcohol consumption in Tibetan population.

We present the observational results from a detailed timing analysis of the black hole candidate EXO 1846-031 during its outburst in 2019 with the observations of Insight-HXMT,NICER and *** outburst can be classified roughly into four different ***-C quasi-periodic oscillations(QPOs)observed by NICER(about 0.1-6 Hz)and Insight-HXMT(about 0.7-8 Hz)are also reported in this ***,we study various physical quantities related to QPO *** QPO rms-frequency relationship in the energy band 1-10 keV indicates that there is a turning pointing in frequency around2 Hz,which is similar to that of GRS 1915+105.A possible hypothesis for the relationship above may be related to the inclination of the source,which may require a high inclination to explain *** relationships between QPO frequency and QPO rms,hardness,total fractional rms and count rate have also been found in other transient sources,which can indicate that the origin of type-C QPOs is non-thermal.

目的了解国内ICU收治患者的营养治疗实施状况。方法对国内116家医院的118个ICU内的患者进行营养治疗实施状况的横断面调查。以2017年4月26日0时所有在ICU内治疗的患者为调查对象,收集患者基本信息、2017年4月25日(即调查日)的营养实施和胃肠道耐受情况,以及患者的28 d临床转归情况。结果调查共收集病例1953例,女631例(32.4%),男1306例(66.9%),缺失16例(0.7%);年龄(64.1±19.3)岁(1950例)。患者GCS、SOFA和APACHEⅡ评分分别为(10.76±4.35)分(1749例)、(5.65±3.52)分(1783例)、(17.14±7.31)分(1792例)。28 d临床转归存活1483例(75.9%),死亡312例(16.0%),失访+缺失158例(8.1%)。除身高和体重(P=0.000)外,男性与女性患者在年龄、病情严重程度及28 d临床转归等方面差异均无统计学意义。1953例患者中,胃肠功能评估为正常或轻度损害占73.7%(1440例),中-重度损害占10.8%(210例),衰竭占1.7%(33例),13.2%(258例)的患者未做评估。截至调查日,69.4%(1356例)的患者已启动肠内营养(EN),36.4%(711例)的患者已启动肠外营养(PN)。调查日有营养摄入的患者1720例(88.1%)。1953例患者中明确有恶心、呕吐反流、误吸、腹痛、腹胀、腹泻(大便次数≥3次/d且量≥500 ml/d)等胃肠道不耐受表现的分别占总人数的4.8%(93例)、5.4%(105例)、0.9%(17例)、8.7%(170例)、27.5%(538例)和4.3%(84例)。在1270例使用EN的病例中,明确存在恶心、呕吐反流、误吸、腹痛、腹胀、腹泻等不耐受症状的分别占3.2%(40例)、4.3%(54例)、0.8%(10例)、4.4%(56例)、26.9%(341例)和5.4%(69例)。入ICU后24 h内开始EN治疗的患者占22.4%(437/1953),48 h内开始的占38.6%(754/1953),72 h内开始的占46.6%(911/1953)。患者入ICU后3 d总热卡(EN+PN非蛋白热卡)达标率为12.9%(78/607),7 d总热卡达标率为18.7%(189/1010),14 d总热卡的达标率为23.0%(305/1325)。入ICU后3、7、14 dEN达标率分别为9.9%(60/607)、15.0%(151/1010)和18.6%(246/1325)。结论目前我国ICU内的绝大多数患者均接受了营养治疗,其中EN的使用率明显高于PN;但EN的开始时间和达标情况仍不理想,且实施营养治疗时未能体现个体化差异,营养治疗的细节仍需要提高。
