This study was conducted to investigate the effects of Chinese medicine granule (CMG, including Cortex Phellodendron, Atractylodes Rhizome, Agastache Rugosa and Gypsum Fibrosum) on absorption and transport of glucose in porcine small intestinal brush border membrane vesicles (BBMVs) under heat stress. Forty-eight 2-month-old Chinese experimental barrows were screened according to weight and litter origin, and then allotted to three groups and treated as follows: Normal temperature control group (NTCG; $23^{\circ}C$), high temperature control group (HTCG; $26^{\circ}C$ for 19 h, $40^{\circ}C$ for 5 h); Chinese medicine granule anti-stress group (CMGG; $26^{\circ}C$ for 19 h, $40^{\circ}C$ for 5 h) (n = 16 per group). The results showed that high temperature treatment decreased (p<0.05) the growth performance and intestinal glucose absorption but there was no change (p>0.05) in the expression of SGLT1 and GLUT2 genes in the small intestine of pigs compared with the NTCG. Dietary supplementation with CMG improved the growth performance, and increased the activity of disaccharidases in duodenum and jejunum of heat stressed pigs (p<0.05). CMG treatment increased (p<0.05) the protein levels of SGLT1 and GLUT2 in the small intestine, and up-regulated (p<0.05) the expression of SGLT1 and GLUT2 genes in the duodenum and jejunum but without changing (p>0.05) them in the ileum compared with the HTCG. These results indicated that CMG treatment significantly improved porcine growth performance, and increased intestinal glucose absorption and transport by BBMVs under heat stress, in addition to up-regulating the expression of SGLT1 and GLUT2 genes in porcine duodenum and jejunum.

The coronavirus disease 2019 (COVID-19) pandemic has become a public health emergency of global concern. In China, traditional Chinese medicine has been widely administered to COVID-19 patients without sufficient evidence. To evaluate the efficacy of Shenhuang Granule (SHG) for treating critically ill patients with COVID-19, we included in this study 118 patients who were admitted to the ICU of Tongji Hospital between January 28, 2020 and March 28, 2020. Among these patients, 33 (27.9%) received standard care plus SHG (treatment group) and 85 (72.1%) received standard care alone (control group). Enrolled patients had a median (IQR) age of 68 (57-75) years, and most (79 [67.1%]) were men. At end point of this study, 83 (70.3%) had died in ICU, 29 (24.5%) had been discharged from ICU, and 6 patients (5.2%) were still in ICU. Compared with control group, mortality was significantly lower in treatment group (45.4% vs. 80%, p < .001). Patients in treatment group were less likely to develop acute respiratory distress syndrome (ARDS) (12 [36.3%] vs. 54 [63.5%], p = 0.012) and cardiac injury (5 [15.1%] vs. 32 [37.6%], p = 0.026), and less likely to receive mechanical ventilation (22 [66.7%] vs. 72 [84.7%], p = 0.028) than those in control group. The median time from ICU admission to discharge was shorter in treatment group (32 [20-73] days vs. 76 [63-79] days, p = 0.0074). These findings suggest that SHG treatment as a complementary therapy might be effective for critically ill adults with COVID-19 and warrant further clinical trials.

Objectives: The purpose of this study is to investigate the composition, origins, and utilization of Jiuwei Zhenxin Granules for anxiety disorders in Chinese medicine. Methods: Studies found in six databases were chosen, and major indicators were analyzed. Results: Jiuwei Zhenxin Granules are modified from Pyeonbojinsimdan on Taepyeonghyeminhwajegukbang. In Jiuwei Zhenxin Granule studies, there were significant effects in nine outcomes in twenty-four studies of primary anxiety disorders and seventeen outcomes were similar in effect to that in the control. Three outcomes in ten studies of secondary anxiety disorders showed significant effects, and five outcomes were similar in effect to that in the control. Conclusions: Jiuwei Zhenxin Granules is a prescription that focuses on harmony of vital energy (qi) and blood, and stability of mind. The significance of the constitution of Jiuwei Zhenxin Granules is similar to that of domestic anxiety disorder studies, so it seems to be applicable to anxiety disorders. With regard to domestic use of Jiuwei Zhenxin Granules, more research is needed on the dosage according to the formulation.

Toxoplasma gondii is a eukaryotic parasite of the phylum Apicomplexa, which infects all warm-blood animals, including humans. In the present study, we examined sequence variation in dense granule 20 (GRA20) genes among T. gondii isolates collected from different hosts and geographical regions worldwide. The complete GRA20 genes were amplified from 16 T. gondii isolates using PCR, sequence were analyzed, and phylogenetic reconstruction was analyzed by maximum parsimony (MP) and maximum likelihood (ML) methods. The results showed that the complete GRA20 gene sequence was 1,586 bp in length among all the isolates used in this study, and the sequence variations in nucleotides were 0-7.9% among all strains. However, removing the type III strains (CTG, VEG), the sequence variations became very low, only 0-0.7%. These results indicated that the GRA20 sequence in type III was more divergence. Phylogenetic analysis of GRA20 sequences using MP and ML methods can differentiate 2 major clonal lineage types (type I and type III) into their respective clusters, indicating the GRA20 gene may represent a novel genetic marker for intraspecific phylogenetic analyses of T. gondii.

Objectives : This study collected and analyzed information related to preventive formulas from continuously published and revised COVID-19 treatment guidelines in various regions of China. Methods : We collected treatment guidelines published in different regions of China and categorized formulas for prevention and medical observation period listed in them according to the editions. The categorized preventive formulas were compared by type and target group. Results : Herbal medicines used for prevention included formulas derived from Korean medical classics, such as Okbyeongpungsan(玉屏風散) and Eunkyosan(銀翹散). The newly composed formulas, totaling over 100, were created by adding, subtracting, and combining formulas such as Sang-gukeum(桑菊飮), Eunkyosan(銀翹散), Sasammaekmundongtang(沙參麥門冬湯), Okbyeongpungsan(玉屏風散), Gwakhyangjeong-gisan(藿香正氣散), and Soshihotang(小柴胡湯). Patent medicines including Huoxiangzhengqi capsule(藿香正氣膠囊), Lianhuaqingwen capsule(連花淸瘟膠囊), Shufengjiedu capsule(疏風解毒膠囊), and Jinhuaqinggan granule(金花淸感顆粒) were frequently used, mainly targeting close contacts. These medicines were used differently depending on the specific population group, such as the general population, the elderly, children, pregnant women, and patients with underlying diseases, and were also applied differently according to the individual's constitution. Conclusion : We were able to identify various background factors contained in the guidelines for the use of preventive formulas presented by TCM group, and understand the social conditions that enabled the group to provide such guidelines. Through this, thorough preparation should be made so that the Korean Medicine can actively respond to another future pandemic.

진균 속에 속하는 종인 Cordyceps는 중국의 전통약제로서, 그 유효성분인 cordycepin이 혈소판 응집에 관여한다는 보고가 있지만 phosphoprotein 조절에 관련된 연구는 미흡하다. 본 연구에서는, cordycepin이 fibrinogen binding에 관여한다고 알려진 PI3k/Akt와 $TXA_2$ 분비 및 과립방출에 관여한다고 알려진 p38와 같은 phosphoprotein의 인산화를 어떻게 조절하며 혈소판응집을 억제시키는지 규명하고자 하였다. 그 결과, cordycepin가 $261.1{\mu}M$의 $IC_{50}$으로 collagen이 유도한 혈소판 응집을 강력하게 억제하였고, PI3K와 Akt의 인산화를 감소시키며 ${\alpha}IIb/{\beta}_3$에 대한 fibrinogen 결합을 농도의존적으로 억제하였다. 또한, cordycepin은 collagen이 촉진시킨 p38의 인산화를 억제함으로써, 과립방출의 지표인 ATP 과 serotonin의 방출을 억제하였고 COX-1과 TXAS의 활성 및 $PLC-{\gamma}_2$ 인산화에 대한 영향없이 $TXA_2$ 생성량을 감소시켰다. 따라서, cordycepin은 PI3K/Akt, p38와 같은 phosphoprotein의 인산화를 억제함으로써 혈소판 응집억제를 나타내는 항혈전 치료 및 예방약물로서 유용한 가치가 있다고 여겨진다.

Zizyphi Spinosi Semen (ZSS), a traditional Chinese folk medicine, has been used for treatment of insomnia and anxiety. This experiment was performed to investigate the anxiolytic-like effect of methanol extract of ZSS (MEZSS) in mice by using the experimental paradigms of anxiety and compared with that of a known anxiolytic, diazepam. In the elevated plus-maze test, it showed that MEZSS (100 mg/kg, p.o.) and diazepam (2.0 mg/kg, p.o.) increased the percentage of time spent on the open arms and the number of open arms entries. MEZSS (50, 100 and 200 mg/kg, p.o.) and diazepam (0.5 mg/kg, p.o.) significantly increased the number of head dips compared with that of control group in the hole-board test. However, MEZSS has no effect on decreasing the locomotor activity, while diazepam (2.0 mg/kg, p.o.) significantly inhibited locomotor activity. MEZSS did not decrease the strength force in the grip strength test, either. In addition, GABAergic involvements were also investigated to understand the possible mechanisms. $GABA_{A}$ receptors subunits and glutamic acid decarboxylase (GAD) were not over expressed, compared with that of the saline group. We also found that MEZSS did not increase chloride influx in cultured cerebellar granule cells. It is concluded that MEZSS might have anxiolytic-like effects, but these effects might not be mediated by GABAergic transmission.

The in vitro maturation (IVM) efficiency of porcine embryos is still low because of poor oocyte quality. Although brilliant cresyl blue positive (BCB+) oocytes with low glucose-6-phosphate dehydrogenase (G6PDH) activity have shown superior quality than BCB negative (-) oocytes with high G6PDH activity, the use of a BCB staining test before IVM is still controversial. This study aimed to shed more light on the subcellular characteristics of porcine oocytes after selection using BCB staining. We assessed germinal vesicle chromatin configuration, cortical granule (CG) migration, mitochondrial distribution, the levels of acetylated lysine 9 of histone H3 (AcH3K9) and nuclear apoptosis features to investigate the correlation between G6PDH activity and these developmentally related features. A pattern of chromatin surrounding the nucleoli was seen in 53.0% of BCB+ oocytes and 77.6% of BCB+ oocytes showed peripherally distributed CGs. After IVM, 48.7% of BCB+ oocytes had a diffused mitochondrial distribution pattern. However, there were no significant differences in the levels of AcH3K9 in the nuclei of blastocysts derived from BCB+ and BCB- oocytes; at the same time, we observed a similar incidence of apoptosis in the BCB+ and control groups. Although this study indicated that G6PDH activity in porcine oocytes was correlated with several subcellular characteristics such as germinal vesicle chromatin configuration, CG migration and mitochondrial distribution, other features such as AcH3K9 level and nuclear apoptotic features were not associated with G6PDH activity and did not validate the BCB staining test. In using this test for selecting porcine oocytes, subcellular characteristics such as the AcH3K9 level and apoptotic nuclear features should also be considered. Adding histone deacetylase inhibitors or apoptosis inhibitors into the culture medium used might improve the efficiency of IVM of BCB+ oocytes.
