[Analysis on quality value transfer of substance benchmarks of Taohong Siwu Decoction].

By preparing 15 batches of substance benchmarks of Taohong Siwu Decoction, the methodology of the characteristic spectrums of substance benchmarks was established. The paste-forming rate range, the contents and the transfer rate range of the index components, hydroxy safflower yellow A, ferulic acid and paeoniflorin, the characteristic peaks and the similarity range of the characteristic spectrums of Taohong Siwu Decoction were determined to define key quality attributes of substance benchmarks of Taohong Siwu Decoction.In the 15 batches of substance benchmarks of Taohong Siwu Decoction, the similarity of characteristic spectrums was higher than 0.

Dynamic profiles of SARS-Cov-2 infection from five Chinese family clusters in the early stage of the COVID-19 pandemic.

Although several cases of family clusters with SARS-Cov-2 infection have been reported, there are still limited data preventing conclusions from being drawn regarding the characteristics and laboratory findings in the COVID-19 population within family clusters. In the present study, we retrospectively collected five family clusters with COVID-19 and summarized the dynamic profiles of the clinical characteristics, laboratory findings, immune markers, treatment and prognosis of this population. Furthermore, we also compared clinical and laboratory data between the SARS-Cov-2 infection with family cluster (n = 21) and those without family cluster (n = 16).

[Particle size of "Cuo San" of famous classical formulas and decoction process with Xiebai San for example].

In this experiment, the decoction process of famous classical formula Xiebai San was determined by optimizing the particle size of "Cuo san" and investigating the decoction process parameters, such as boiling container, water volume and duration. Xiebai San was taken as an example to explore the study method of the "Cuo san" in the famous classical formulas. The specific chromatogram of Xiebai San and the determination method of glycyrrhizin and glycyrrhizic acid in Xiebai San were established.

Arterial hyperenhancement of small intrahepatic cholangiocarcinomas correlates with microvessel counts and patient survival.

Background: To compare outcomes of patients with arterially hyperenhancing intrahepatic cholangiocarcinomas (ICC) and arterially hypoenhancing ICCs after partial hepatectomy in a cohort with an analysis of prognostic factors.

Methods: From June 2009 to October 2011, a prospective cohort of 68 patients with single resectable ICCs (≤5 cm in diameter) underwent gadolinium contrast-enhanced dynamic-phase magnetic resonance imaging and were treated with partial hepatectomy. Patients were divided into those with arterially hyperenhancing ICCs (n = 28) or arterially hypoenhancing ICCs (n = 40).

[In vitro transdermal permeation of main compositions in Baimai Ointment].

To establish a determination method for the contents of ammonium glycyrrhetate,nardosinone,and curcumin in transdermal receptor liquid of Baimai Ointment,and investigate the percutaneous permeability of Baimai Ointment and the effects of two kinds of penetration enhancers on percutaneous absorption of three components. The contents of ammonium glycyrrhetate,nardosinone,and curcumin in transdermal receptor liquid were determined by high pressure liquid chromatography( HPLC). The vertical modified Franz diffusion cell was used to perform a transdermal experiment in vitro with the abdominal skin of mice( treated and untreated).

Small Intrahepatic Cholangiocarcinoma and Hepatocellular Carcinoma in Cirrhotic Livers May Share Similar Enhancement Patterns at Multiphase Dynamic MR Imaging.

Purpose To assess the accuracy of magnetic resonance (MR) imaging-based differential diagnosis of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) in a cohort of patients with focal liver lesions and cirrhosis. Materials and Methods This study was institutional review board approved, and the requirement for informed consent was waived. Between January 2009 and December 2014, a cohort of cirrhotic patients, including 71 with ICC and 612 with HCC, underwent unenhanced T1- and T2-weighted MR imaging, gadolinium-based contrast material-enhanced dynamic phase imaging, and partial hepatectomy.

Risk factors and surgical outcomes for spontaneous rupture of BCLC stages A and B hepatocellular carcinoma: a case-control study.

Aim: To investigate the risk factors and surgical outcomes for spontaneous rupture of Barcelona Clinic Liver Cancer (BCLC) stages A and B hepatocellular carcinoma (HCC).

Methods: From April 2002 to November 2006, 92 consecutive patients with spontaneous rupture of BCLC stage A or B HCC undergoing hepatic resection were included in a case group. A control arm of 184 cases (1:2 ratio) was chosen by matching the age, sex, BCLC stage and time of admission among the 2904 consecutive patients with non-ruptured HCC undergoing hepatic resection.

Prealbumin is predictive for postoperative liver insufficiency in patients undergoing liver resection.

Aim: To investigate the risk factors for postoperative liver insufficiency in patients with Child-Pugh class A liver function undergoing liver resection.

Methods: A total of 427 consecutive patients undergoing partial hepatectomy from October 2007 to April 2011 at a single center (Department of Hepatic SurgeryI, Eastern Hepatobiliary Surgery Hospital, Shanghai, China) were included in the study. All the patients had preoperative liver function of Child-Pugh class A and were diagnosed as having primary liver cancer by postoperative histopathology.

Resistance mechanisms to chlorpyrifos and F392W mutation frequencies in the acetylcholine esterase ace1 allele of field populations of the tobacco whitefly, Bemisia tabaci in China.

The tobacco whitefly B-biotype Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) is a worldwide pest of many crops. In China, chlorpyrifos has been used to control this insect for many years and is still being used despite the fact that some resistance has been reported. To combat resistance and maintain good control efficiency of chlorpyrifos, it is essential to understand resistance mechanisms.

[Can As2O3 improve the prognosis of childhood acute promyelocytic leukemia?--A single center experience].

Objective: To retrospectively analyze the treatment outcomes and side effects of childhood acute promyelocytic leukemia (APL) treated with all-trans retinoic acid (ATRA) or ATRA + arsenic trioxide (As2O3).

Methods: From 1992 to 2006, 45 patients with newly diagnosed APL were enrolled. All of them were PML-RAR alpha positive.

[Clinical significance of detection of AML1/ETO fusion transcripts in childhood AML using real-time quantitative reverse transcription polymerase chain reaction].

This study was aimed to investigate the clinical value of quantification of AML1/ETO fusion transcripts using real-time reverse transcription PCR. Fourteen AML1/ETO positive children out of 52 AML children were selected. A serial dilution of AML1/ETO plasmid was used as a template for the AML1/ETO real-time PCR.
