		                        			Objective To observe the effects of Wuzi Yanzong Pill(WYP)on motor function in a mouse model of Parkinson's disease(PD)and to explore its potential mechanisms.Methods Twenty-four male C57BL/6 mice were randomly divided into control group,model group and WYP group,with 8 mice in each group.Mice in model and WYP group were intraperitoneally injected with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine for 7 consecutive days to establish a PD model.From the 1st day of model preparation,mice in WYP group were gavaged with WYP solution[16 g/(kg·d)]twice daily for 14 consecutive days.At the same time,mice in control group and model group were gavaged with 0.9%NaCl solution[50 ml/(kg·d)]twice a day.Gait experiment was utilized to assess the behavioral performance of mice in each group.Immunofluorescence staining was conducted to detect the number of tyrosine hydroxylase(TH)-positive cells in the substantia nigra region,the fluorescence intensity of nuclear factor E2-related factor 2(Nrf2),and the number of NeuN neurons co-labeled with Nrf2 in each group.Western blotting was employed to determine the expression levels of TH,Kelch-like ECH-associated protein 1(Keap-1),Nrf2,and heme oxygenase-1(HO-1)in the brain tissue of mice in each group.Results The gait experiment results showed that,compared with control group,standing time of the left front paw,right front paw,left hind paw,and right hind paw of the mice in model group was significantly shortened(P<0.01),while swinging time of the left front paw,right front paw,left hind paw,and right hind paw was significantly prolonged(P<0.05).Compared with model group,standing time of the left front paw and right hind paw of the mice in WYP group was significantly prolonged(P<0.05),while swing time of the left front paw and right front paw was significantly shortened(P<0.05).Immunofluorescence staining and Western blotting results showed that,compared with control group,in model group the number of TH-positive cells,average fluorescence intensity of Nrf2,and HO-1 levels decreased(P<0.01),while the Keap-1 protein level increased(P<0.01),and the number of Nrf2 expression on NeuN neurons decreased(P<0.001).Compared with model group,the number of TH-positive cells,average fluorescence intensity of Nrf2,HO-1 level,and the number of Nrf2 expression on NeuN neurons in the brain tissue of mice in WYP group increased(P<0.05),while Keap-1 protein level decreased(P<0.05).Conclusions WYP could alleviate the motor dysfunction and protect dopaminergic neurons in PD mice.The underlying mechanism may be related to the regulation of Keap-1/Nrf2/HO-1 pathway to inhibit oxidative stress response.

		                        			Schisandra chinensis, a traditional Chinese medicinal herb, is rich in chemical constituents, including lignans, triterpenes, polysaccharides, and volatile oils. Clinically, it is commonly used to treat cardiovascular, cerebrovascular, liver, gastrointestinal, and respiratory diseases. Modern pharmacological studies have shown that S. chinensis extract and monomers have multiple pharmacological activities in lowering liver fat, alleviating insulin resistance, and resisting oxidative stress, and have good application prospects in alleviating nonalcoholic fatty liver disease(NAFLD). Therefore, this study reviewed the research progress on chemical constituents of S. chinensis and its effect on NAFLD in recent years to provide references for the research on S. chinensis in the treatment of NAFLD.

		                        			Objective: To compare the short-term and long-term outcomes between robotic-assisted and laparoscopic-assisted radical right hemicolectomy in patients with adenocarcinoma of the right colon. Methods: Retrospective review of a prospectively collected database identified 288 right colon cancer patients who underwent either robotic-assisted (n=57) or laparoscopic-assisted right hemicolectomy (n=231) between October 2014 and October 2020 at Department of Gastrointestinal Surgery, the Affiliated Hospital of Qingdao University. There were 161 males and 127 females, aging (60.3±12.8) years (range: 17 to 86 years). After propensity score matching as 1∶4 between robotic-assisted and laparoscopic-assisted right hemicolectomy, there were 56 cases in robotic group and 176 cases in laparoscipic group. Perioperative outcomes and overall survival were compared between the two groups using t test, Wilcoxon rank sum test, χ2 test, Fisher exact test, Kaplan-Meier method and Log-rank test, respectively. Results: The total operative time was similar between the robotic and laparoscopic group ((206.9±60.7) minutes vs. (219.9±56.3) minutes, t=-1.477, P=0.141). Intraoperative bleeding was less in the robotic group (50 (20) ml vs. 50 (50) ml, Z=-4.591, P<0.01), while the number of lymph nodes retrieved was significantly higher (36.0±10.0 vs. 29.0±10.1, t=4.491, P<0.01). Patients in robotic group experienced significantly shorter hospital stay, shorter time to first flatus, and defecation (t: -2.888, -2.946, -2.328, all P<0.05). Moreover, the overall peri-operative complication rate was similar between robotic and laparoscopic group (17.9% vs. 22.7%, χ²=0.596,P=0.465). The 3-year overall survival were 92.9% and 87.9% respectively and the 3-year disease-free survival rates were 83.1% and 82.6% with no statistical significance between the robotic and laparoscopic group (P>0.05). Conclusions: Compared to laparoscopic-assisted right hemicolectomy, robot-assisted right hemicolectomy could improve some short-term clinical outcomes. The two procedures are both achieving comparable survival.

		                        			 Objective: Dianjixueteng is a geoherb in Yunnan Province, the source plant of which is Kadsura interior. However, the formation of this geoherb is not clear in genetic mechanism, in which genome size is the first step that should be known on the genomic level. In this study we aimed to estimate the genome sizes of source plants of K. interior and three related herbs K. heteroclita, K. longipedunculata, and K. coccinea by flow cytometry (FCM) and make a comparison. Methods: The genome sizes of K. interior, K. heteroclita, K. longipedunculata and K. coccinea, i.e., the source plants of Dianjixueteng and its relative medicinal materials, were estimated by FCM. The nuclei of K. interior were isolated using modified LB01 buffer, for the rest species, by the Galbraith's buffer. Results: The genome sizes of K. interior, K. heteroclita, K. longipedunculata, and K. coccinea were 7.36, 7.12, 7.01, and 5.15 pg/1C, respectively. Genome size of K. interior had no significant variation with those of K. heteroclita and K. longipedunculata (P = 0.296), which was significantly larger than that of K. coccinea. Conclusion: Genome size can not distinguish K. interior from K. heteroclita and K. longipedunculata, but could distinguish them from K. coccinea, which lays the foundation for future studies on genetic mechanism of the geoherb formation.

		                        			Nagilactone E (NLE), a natural product with anticancer activities, is isolated from Podocarpus nagi. In this study, we reported that NLE increased programmed death ligand 1 (PD-L1) expressions at both protein and mRNA levels in human lung cancer cells, and enhanced its localization on the cell membrane. Mechanistically, NLE increased the phosphorylation and expression of c-Jun, and promoted the localization of c-Jun in the nucleus, while silencing of c-Jun by small interfering RNA (siRNA) reduced NLE-induced PD-L1. Further study showed that NLE activated the c-Jun N-terminal kinases (JNK), the upstream of c-Jun, and its inhibitor SP600125 reversed the NLE-increased PD-L1. Moreover, NLE-induced PD-L1 increased the binding intensity of PD-1 on the cell surface. In summary, NLE upregulates the expression of PD-L1 in lung cancer cells through the activation of JNK-c-Jun axis, which has the potential to combine with the PD-1/PD-L1 antibody therapies in lung cancer.

		                        			The application of chemical fingerprint to evaluate the quality of traditional Chinese medicine has been widely accepted and used in many countries. However,only by analyzing the type and content of its chemical components to evaluate the quality of traditional Chinese medicines,the gold standard of quality evaluation by evaluating pharmacodynamic effects is ignored. The study of Chinese medicinal spectrum-effect relationships combining the chemical composition with the pharmacodynamic activity of traditional Chinese medicine,which can evaluate the quality of traditional Chinese medicine from more comprehensive and different angles,has been applied in many fields of traditional Chinese medicine research. This paper mainly summarizes the research methods of the Chinese medicinal spectrum-effect relationships and its application in the field of traditional Chinese medicine study,and provides reference for the research,development and application of the Chinese medicinal spectrum-effect relationships.

		                        			To provide a scientific evidence for the quality control of Codonopsis Radix, a method was established for determining the content of three free carbohydrates of Codonopsis Radix. The developed method showed good linearity. The calibration curves were linear within the range of 2.312 5-18.500 0 μg for sucrose, 1.500 0-12.000 0 μg for glucose, and 2.000 0-16.000 0 μg for fructose, resgectwely. The recoveries varied between 96.31%-101.8%. The method is simple, accurate and reproducible, and can be used for determining the content of sucrose, glucose and fructose of Codonopsis Radix. The results showed that different cultivation measures had an effect on the content of three free carbohydrates of Codonopsis Radix. According to the content of sucrose, using Zhuanggenling>not using Zhuanggenling. While, not pinching, shelving>not pinching, not shelving>pinching, not shelving>pinching, shelving. According to the content of glucose and fructose, not using Zhuanggenling>using Zhuanggenling. While, pinching, shelving>not pinching, not shelving>not pinching, shelving>pinching, not shelving. In consideration of the differences of sweetness and content of the three free carbohydrates in Codonopsis Radix, we recommend that the content of free carbohydrates could be considered as the marker to evaluate the quality of Codonopsis Radix.
