[Origin, development, and modern application value of Chinese herbal lozenges].

Lozenge is one of the traditional dosage forms of Chinese medicine. It has been recorded in traditional Chinese medical classics of all dynasties since the Eastern Han Dynasty and has been developing and evolving continuously. The unique pharmaceutical methods and application scope are the driving force of its emergence, existence, and development.

[Textual research on medicinal blue herbs].

In this paper, through the collection and collation of ancient herbs, medical books and prescriptions, combined with modern literature, the historical changes of the name, origin, position, medicinal parts, collection, processing and processing of bluegrass were systematically combed and verified.It can be seen from the research that bluegrass was first used as medicine by the fruit, namely blueberry, which was originally Polygonum tinctorium. Since the Ming and Qing Dynasties, blueberry was rarely used, and it has been no longer used medicinally.

[Nasal submicron emulsion of Scutellariae Radix extract preparation technology research based on phase transfer of solute technology].

Based on the demand of nasal drug delivery high drug loadings, using the unique phase transfer of solute, integrating the phospholipid complex preparation and submicron emulsion molding process of Scutellariae Radix extract, the study obtained the preparation of the high drug loadings submicron emulsion of Scutellariae Radix extract. In the study of drug solution dispersion method, the uniformity of drug dispersed as the evaluation index, the traditional mixing method, grinding, homogenate and solute phase transfer technology were investigated, and the solute phase transfer technology was adopted in the last. With the adoption of new technology, the drug loading capacity reached 1.

Caffeine and dithiothreitol delay ovine oocyte ageing.

The intracellular glutathione levels and developmental competence of aged oocytes after parthenogenetic activation, somatic cell nuclear transfer and intracytoplasmic sperm injection in the presence or absence of caffeine or dithiothreitol (DTT) were examined. The following results were found: (1) ovine oocytes were fully aged 30 h post-onset of maturation culture; (2) the appropriate concentrations of caffeine and DTT for oocyte culture were 5 mM and 1 mM, respectively; (3) when nuclear transfer-reconstructed embryos were treated with caffeine or DTT following fusion, no increase in the frequency of development to blastocyst was observed (P > 0.05), but the cell numbers of blastocysts increased (P < 0.

Liver support therapy with molecular adsorbents recirculating system in liver failure: a summary of 252 cases from 14 centers in China.

Background: A liver support therapy, named molecular adsorbents recirculating system (MARS), has been used for more than 700 liver failure patients in China. We made here a summary to evaluate the effects of MARS treatment in different applications with emphasis on hepatitis B virus (HBV) based liver failure.

Methods: This report analyzed data of 252 patients (mean age (44.

[Application of molecular adsorbents recirculating system in the treatment for liver failure of hepatitis B].

Objective: To evaluate the effect of treatments with the molecular adsorbents recirculating system (MARS) on liver failure patients of severe hepatitis B, in order to seek a safe and effective therapeutic method which contribute to the improved survival rate for severe hepatitis patients.

Methods: 52 liver failure patients of severe hepatitis B were performed intermittent MARS therapy for 6 to 8 hours per time in addition to standard medical treatment. Parameters in blood chemical data were collected before and after every treatment and analyzed in comparison with those parameters from controlled groups by means of plasma exchange and standard medical therapy.
