Objective: To study the new device and technology in prepartion of superfined Chinese herbal medicine powders. Methods: Improving the Trost jet mill was to divide continually the feed and the coarse grains classified from a circular disc into two two phase flow by means of a especial four way pipe in mixing. and to impact with high speed oppositely each other, the superfined powders are prepared. Results: The superfined powders of ginseng, boat fruited sterculia seed and balsam pear are successfully prepared to guarantee 10~15?m in diameter. Conclusions: It is very effective to pulverize Chinese herbal medicine with this device in mass production.

Objective To study the effect of survivin anfisense oligonucleotides (ASODN)combined with quercetin on proliferation, apoptosis and cell cycle of a hepatocellular carcinoma cell line SSMC-7721 cells. Methods Human hepatocellular carcinoma cell line SSMC-7721 was cultured in vitro,and cells on logarithmic growth phase were used for this experiment. Cell proliferation was measured by MTT assay. The apoptotic rate and cell cycle were examined by flow cytometer (FCM). Morphological change of apoptotic cells were observed by fluorescent microscope. The expression of survivin gene was detected by the method of immunohistochemistry staining and RT-PCR on the mRNA and protein level. Results After sealing survivin gene with ASODN, the proliferation of SSMC-7721 cells was inhibited markedly. FCM analysis showed that there appeared an obvious apoptosis peak after transfection. The inhibitory effect of combined administration of survivin ASODN and quercetin on cell proliferation was much stronger than that of the single way. The result of immunohistochemical and RT-PCR assays showed that survivin ASODN and quercetin inhibited the expression of survivin gene. Conclusion Combined survivin ASODN with quercetin significantly inhibit cell proliferation, down-regulate survivin gene expression and induce the apoptosis of SSMC-7721 cells.

Diabetes diet management plays an important role in the treatment of diabetes. "Controlling diet" is the most basic and important part of diabetes treatment. Patients with mild diabetes can control blood glucose through diet therapy. Effective diet management assessment can quickly discover the deficiencies of diet self-management in diabetic patients. Artificial intelligence is widely used in the medical field. This article will briefly introduce the role and application progress of artificial intelligence technology in diabetes diet management, including diet recommendation and automatic monitoring.

As the search for effective treatments for COVID-19 continues, the high mortality rate among critically ill patients in Intensive Care Units (ICU) presents a profound challenge. This study explores the potential benefits of traditional Chinese medicine (TCM) as a supplementary treatment for severe COVID-19. A total of 110 critically ill COVID-19 patients at the Intensive Care Unit (ICU) of Vulcan Hill Hospital between Feb., 2020, and April, 2020 (Wuhan, China) participated in this observational study. All patients received standard supportive care protocols, with a subset of 81 also receiving TCM as an adjunct treatment. Clinical characteristics during the treatment period and the clinical outcome of each patient were closely monitored and analysed. Our findings indicated that the TCM group exhibited a significantly lower mortality rate compared with the non-TCM group (16 of 81 vs 24 of 29; 0.3 vs 2.3 person/month). In the adjusted Cox proportional hazards models, TCM treatment was associated with improved survival odds (P < 0.001). Furthermore, the analysis also revealed that TCM treatment could partially mitigate inflammatory responses, as evidenced by the reduced levels of proinflammatory cytokines, and contribute to the recovery of multiple organic functions, thereby potentially increasing the survival rate of critically ill COVID-19 patients.
