目的探讨乳腺癌患者代谢组学相关指标联合检测用于中医诊断的效应,方法 2020年1月至12月,对珠海市中西医结合医院乳腺癌手术治疗后生存3年以上的90例患者调查研究。根据乳腺癌中医辨证分型不同将患者分为气血两虚证组30例、肝郁气滞证组30例和冲任失调证组30例。比较乳腺癌组和对照组血清微量元素和血清特征指标含量的统计学差异,比较3种中医证型乳腺癌组患者血清特征指标含量的统计学差异;多因素相关性分析血清特征指标、血清微量元素含量与乳腺癌中医证型的综合影响。结果乳腺癌组患者血清中钙、镁含量低于健康组,血清中磷、锌含量高于健康组(P<0.05);乳腺癌组患者血清中白细胞介素(IL)-6、可溶性IL-6受体(sIL-6R)和神经生长因子(NGF)指标含量均高于健康组(P<0.05);3种中医证型乳腺癌组患者血清特征指标含量的比较,气血两虚证组患者血清中IL-6、sIL-6R和NGF指标含量均高于肝郁气滞证组和冲任失调证组患者(P<0.05)。结论与健康人群相比,乳腺癌患者代谢组学相关指标(钙、镁、锌、磷、IL-6、sIL-6R、NGF)变化显著,联合检测代谢血液相关指标有利于进行中医诊断。

Background: Hypoxia is a primary cause of mountain sickness and a common pathological condition in patients with heart failure, shock, stroke, and chronic obstructive pulmonary disease(COPD). Thus far, little advancement in countering hypoxic damage has been achieved, and one of the main reasons is the absence of an ideal algorithm or calculation method to normalize hypoxia tolerance scores when evaluating an animal model. In this study, we improved a traditional calculation formula for assessment of hypoxia ***: We used a sealed bottle model in which the oxygen is gradually consumed by a mouse inside. To evaluate the hypoxia tolerance of mice, the survival time(ST) of the mouse is recorded and was used to calculate standard hypoxia tolerance time(STT) and adjusted standard hypoxia tolerance time(ASTT). Mice administered with methazolamide and saline were used as positive and negative controls, ***: Since mice were grouped according to either body weight(BW) or bottle volume, we found a strongly negative correlation between STT and BW instead of between STT and bottle volume, suggesting that different BWs could cause false positive or negative errors in the STT results. Furthermore, both false positive and negative errors could be rectified when ASTT was used as the evaluation index. Screening for anti-hypoxic medicines by using mice as the experimental subjects would provide more credible results with the improved ASTT method than with the STT ***: ASTT could be a better index than STT for the evaluation of hypoxia tolerance abilities as it could eliminate the impact of animal BW.

通过在香菇培养料中投放一定浓度的重金属镉(Cd),研究香菇子实体对Cd的吸收富集规律。结果表明,香菇子实体对培养料中Cd的吸收富集规律为y=541.77x2.938(2R2=0.9135)(x、y分别为培养料、香菇中Cd的含量),富集系数达到10.39～18.00,当香菇子实体中Cd的含量为y=1.5mg·kg-1时,培养料中Cd的临界含量值x=0.1347mg·kg-1。分别选择3个香菇主栽品种、两种不同栽培方式进行比较试验,研究香菇对Cd的积累特性。结果表明,Cd低富集的品种为"庆元9015",比对镉积累最多的"庆科20"Cd含量降低33.19%,Cd低富集的栽培方式为"离地层架栽培方式"。据此形成了香菇中重金属Cd的综合控防技术,为香菇质量安全控制提供依据。

Common bile duct(CBD)stones are a frequent problem in Chinese populations,and their incidence is particularly high in certain areas(Wang et al.,2013).In recent years,laparoscopic common bile duct exploration(LCBDE)and endoscopic retrograde cholangiopancreatography(ERCP)have been the main surgical procedures for CBD stones,although each has different advantages and disadvantages in the treatment of choledocholithiasis(Loor et al.,2017;zhou et al.,2017).

具有间隙约束的模式匹配是序列模式挖掘的关键问题之一.一次性条件约束是要求序列中每个位置的字符最多只能使用一次,在序列模式挖掘中采用一次性条件约束更加合理.但是目前,间隙约束多为非负间隙,非负间隙对字符串中每个字符的出现顺序具有严格的约束,一定程度上限定了匹配的灵活性.为此,提出了一般间隙及一次性条件的严格模式匹配问题;之后,理论证明了该问题的计算复杂性为NP-Hard问题.为了对该问题进行有效求解,在网树结构上构建了动态更新结点信息的启发式求解算法(dynamically changing node property,简称DCNP).该算法动态地更新各个结点的树根路径数、叶子路径数和树根-叶子路径数等,进而每次可以获得一个较优的出现;之后,迭代这一过程.为了有效地提高DCNP算法速度,避免动态更新大量的结点信息,提出了Checking机制,使得DCNP算法仅在可能产生内部重复出现的时候才进行动态更新.理论分析了DCNP算法的时间复杂度和空间复杂度.大量实验结果验证了DCNP算法具有良好的求解性能.
