HIV/AIDS is one of the most serious public health challenges globally. Despite the great efforts that are being devoted to prevent,treat and to better understand the disease,it is one of the main causes of morbidity and mortality worldwide. Currently,there are 30 drugs or combinations of drugs approved by FDA. Because of the side-effects,price and drug resistance,it is essential to discover new targets,to develop new technology and to find new anti-HIV drugs. This review summarizes the major targets and assays currently used in anti-HIV drug screening.

Background: Mucosal-associated invariant T(MAIT) cells are systemically depleted in human immunodeficiency virus type 1(HIV-1) infected patients and are not replenished even after successful combined antiretroviral therapy(cART).This study aimed to identify the mechanism underlying MAIT cell ***: In the present study, we applied flow cytometry, single-cell RNA sequencing and immunohistochemical staining to evaluate the characteristics of pyroptotic MAIT cells in a total of 127 HIV-1 infected individuals, including 69 treatment-naive patients, 28 complete responders, 15 immunological non-responders, and 15 elite controllers, at the Fifth Medical Center of Chinese PLA General Hospital, Beijing, ***: Single-cell transcriptomic profiles revealed that circulating MAIT cells from HIV-1 infected subjects were highly activated, with upregulation of pyroptosis-related genes. Further analysis revealed that increased frequencies of pyroptotic MAIT cells correlated with markers of systemic T-cell activation, microbial translocation, and intestinal damage in cART-naive patients and poor CD4+ T-cell recovery in long-term cART patients. Immunohistochemical staining revealed that MAIT cells in the gut mucosa of HIV-1 infected patients exhibited a strong active gasdermin-D(GSDMD, marker of pyroptosis) signal near the cavity side, suggesting that these MAIT cells underwent active pyroptosis in the colorectal mucosa. Increased levels of the proinflammatory cytokines interleukin-12(IL-12) and IL-18 were observed in HIV-1 infected patients. In addition, activated MAIT cells exhibited an increased pyroptotic phenotype after being triggered by HIV-1 virions, T-cell receptor signals, IL-12 plus IL-18, and combinations of these factors, in ***: Activation-induced MAIT cell pyroptosis contributes to the loss of MAIT cells in HIV-1 infected patients,which could potentiate disease progression and poor immune reconstitution.

A universal platform with M_n doping and hyaluronic acid （HA） modification, based on mesoporous silica （mSiO2）, was designed and used as a basic multifunctional material with magnetic resonance （MR） imaging. Furthermore, we added flexible functions through the addition of functional molecules. Specially, two typical compounds, hydrophobic perfluorooctyl bromide （PFOB） and hydrophilic doxorubicin （DOX）, were loaded into the channels to obtain PFOB@Mn@mSiO2@HA （PMMH） or DOX@Mn@mSiO2@HA （DMMH） or imaging and therapy, respectively. The were highly targeted to the lymph system in nanoparticles for dual-mode imaging PMMH and DMMH nanoparticles vitro and in vivo. MR and ultrasound imaging of PMMH nanoparticles were performed in the lymph system, while MR imaging and chemotherapy of DMMH nanoparticles was used to detect cancer. These results showed that both PMMH and DMMH nanoparficles can be designed with high lymph targeting efficiency. PMMH nanoparticles are a dual-mode contrast agent for both ultrasound and MR imaging for the lymph system and DMMH nanoparticles are powerful agents for the combined diagnosis and therapy of cancer in vivo.

Next-generation sequencing(NGS) technology is capable of sequencing millions or billions of DNA molecules ***, it represents a promising tool for the analysis of molecular targets for the initial diagnosis of disease, monitoring of disease progression, and identifying the mechanism of drug resistance. On behalf of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology(CSCO) and the China Actionable Genome Consortium(CAGC), the present expert group hereby proposes advisory guidelines on clinical applications of NGS technology for the analysis of cancer driver genes for precision cancer therapy. This group comprises an assembly of laboratory cancer geneticists, clinical oncologists, bioinformaticians,pathologists, and other professionals. After multiple rounds of discussions and revisions, the expert group has reached a preliminary consensus on the need of NGS in clinical diagnosis, its regulation, and compliance standards in clinical sample collection. Moreover, it has prepared NGS criteria, the sequencing standard operation procedure(SOP), data analysis, report, and NGS platform certification and validation.

目的构建熵权-逼近理想解排序法(technique for order preferenceby similarity to ideal solution,TOPSIS)模型,通过多指标成分含量测定的分析比较,为优选三棱Sparganii Rhizoma醋制方法提供科学依据。方法采用醋炙法、醋烤法、醋蒸法、醋煮法4种不同醋制方法对三棱进行炮制加工,HPLC法测定对羟基苯甲酸、香草酸、香兰素、对羟基苯甲醛、阿魏酸5种成分含量变化,并以上述5种成分的含量作为评价指标,利用熵权法测定不同评价指标的信息熵以确定各评价指标权重,利用熵权法加权生成的数据进行TOPSIS模型分析,通过讨论正理想解和负理想解,对三棱醋制方法进行综合分析评价,进而优选三棱最佳醋制方法。结果不同方法醋制的三棱成分含量差异较大,醋炙法炮制后,对羟基苯甲酸、对羟基苯甲醛、香兰素成分含量显著增加;醋煮法炮制后,阿魏酸、香兰素成分含量显著降低,其他无显著变化。经熵权-TOPSIS模型测算,三棱的生品、醋炙品、醋蒸品、醋烤品、醋煮品的相对接近度分别为0.193、0.932、0.227、0.523、0.082,可知三棱不同醋制方法中醋炙法最佳,醋烤法与醋蒸法次之,醋煮法最差。结论基于熵权-TOPSIS模型优选出三棱最佳醋制方法为醋炙法,为中药炮制工艺的选择与临床炮制品的合理使用提供科学依据。

在内侧颞叶癫痫(mTLE)中,内侧颞叶与皮层及皮层下结构参与了癫痫活动的起源与传播。基于Granger因果性(GC)检验方法,对脑电联合功能磁共振(EEG-fMRI)数据进行分析,研究内侧颞叶在mTLE中的作用。以内侧颞叶激活区域为参考区域,计算参考区域与大脑其余每个体素点之间的Granger因果关系,并映射到全脑,形成Granger因果图(GCM)。结果表明,内侧颞叶将癫痫活动传播到外侧颞叶、额叶、顶叶及丘脑等区域,同时受到脑岛、壳核以及丘脑等区域脑活动的影响,提示内侧颞叶在mTLE痫样发放的传播环路中具有关键作用。

为探索培养基改良剂的特性及其对黑麦草生长特性的影响,本文首先以全磷石膏、全营养土和添加了改良剂的磷石膏(改良剂包括稻壳粉、玉米秸杆粉、油菜秸杆粉、煤渣、石英砂等)为基质种植黑麦草,观察其生长表现;然后用稻壳粉和煤渣分别以5种比例加入磷石膏(磷石膏:稻壳粉=20:1~60:1,磷石膏:煤渣=3:1~20:1)作为基质并以全营养土、全磷石膏为对照种植黑麦草,分析黑麦草的生长特性和基质的理化指标,评价改良效果。结果表明,添加改良剂后黑麦草的生长表现显著优于全磷石膏组;生长表现最好的两个组分别是磷石膏:稻壳粉(20:1)和磷石膏:稻壳粉(30:1);在一定范围内,稻壳粉添加越多越利于黑麦草生长,煤渣添加越多越不利于黑麦草生长;稻壳粉或煤渣可改善基质的pH、SMC和容重,且用量越大改善效果越明显。因此,稻壳粉是比较理想的磷石膏改良剂,基质的容重、毛管孔隙度及SMC可用于评价磷石膏改良剂的改良效果。
