Zinc supplementation and light intensity affect 2-acetyl-1-pyrroline (2AP) formation in fragrant rice.

BACKGROUND: Improving the yield and aroma content of fragrant rice is the focus of fragrant rice research. Light and Zinc (Zn) management generally cause regulations in the 2-acetyl-1-pyrroline (2AP) accumulation in fragrant rice. In addition, Zn promotes rice growth and improves rice yield, which has the potential to compensate for the negative impact of low light on fragrant rice yield. However, the potential of Zn to improve fragrant rice yield and 2AP content under shading conditions has not been verified. METHODS: Field experiments were conducted in the rice season (May-September) in 2019 to 2021. Two light i.e., normal light (NL) and low light (LL) and four Zn levels i.e., 0 kg Zn ha- 1 (N0), 1 kg Zn ha- 1 (Zn1), 2 kg Zn ha- 1(Zn2), and 3 kg Zn ha- 1 (Zn3), which applied at booting stage was set up. The grain yield, 2AP contents, Zn content in polished rice, photosynthesis related indicators, MDA content, antioxidant enzyme activity and the biochemical parameters related to 2AP formation were investigated. RESULTS: Shading reduced yield by 8.74% and increased 2AP content by 24.37%. In addition, shading reduced net photosynthetic rate (Pn), superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT), and increased proline, γ-aminobutyric acid (GABA), and pyrroline-5-carboxylic acid (P5C), proline dehydrogenase (PDH), △1-pyrroline-5-carboxylic acid synthetase (P5CS), malondialdehyde (MDA). With increasing Zn application levels, yield, 2AP, Zn content in polished rice, Pn, proline, P5C, GABA, PDH, P5CS, SOD, CAT and POD increased, and MDA decreased. Significant Light and Zn interaction effect on 2AP content was detected, and both shading and increasing Zn application increased the 2AP content. CONCLUSION: Shading can increase the 2AP content but reduce the yield of fragrant rice. Increasing Zn application under shading conditions can further promote the biosynthesis of 2AP, but the effect of improving yield is limited.

Notoginsenoside R1 attenuates breast cancer progression by targeting CCND2 and YBX3 / 中华医学杂志(英文版)

BACKGROUND@#Breast cancer (BC) is a common malignancy with highly female incidence. So far the function of notoginsenoside R1 (NGR1), the extract from Panax notoginseng, has not been clearly elucidated in BC.@*METHODS@#Optimal culture concentration and time of NGR1 were investigated by cell counting kit-8 assay. Cell proliferation ability was measured by colony formation assays. Transwell assay was used to detect the effect of NGR1 on cell migration and invasion. The apoptosis rate of cells between each group was measured by TUNEL assay.@*RESULTS@#NGR1 treatment has an inhibitory effect on proliferation, migration, invasion, and angiogenesis and a stimulating effect on cell cycle arrest and apoptosis of Michigan Cancer Foundation-7 (MCF-7) cells. The 50% growth inhibitory concentration for MCF-7 cells at 24 h was 148.9 mmol/L. The proportions of MCF-7 cells arrested in the G0/G1 phase were 36.94±6.78%, 45.06±5.60%, and 59.46±5.60% in the control group, 75, and 150 mmol/L groups, respectively. Furthermore, we revealed that NGR1 treatment attenuates BC progression by targeted downregulating CCND2 and YBX3 genes. Additionally, YBX3 activates phosphatidylinositol 3-phosphate kinase (PI3K)/protein kinase B (Akt) signaling pathway by activating kirsten rat sarcoma viral oncogene, which is an activator of the PI3K/Akt signaling pathway.@*CONCLUSION@#These results suggest that NGR1 can act as an efficacious drug candidate that targets the YBX3/PI3K/Akt axis in patients with BC.

Therapeutic observation of grain-sized moxibustion for chemotherapy-induced myelosuppression for non-small cell lungcancer / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of grain-sized moxibustion in treating chemotherapy-induced myelosuppression for non-small cell lung cancer (NSCLC) and its effect on quality of life (QOL). Methods: Eighty NSCLC patients admitted to the Inpatient Department of Zhejiang Cancer Hospital between September 2016 and March 2018 were recruited and divided into an observation group and a control group by random number method, with 40 cases in each group. The two groups both received chemotherapy with paclitaxel plus cisplatin (TP regimen). The control group received oral administration of leucogen tablets starting from the first day of chemotherapy, 20 mg each time, three times a day, for consecutive 14 d; the observation group was additionally given grain-sized moxibustion, once a day, five days per week at a two-day interval, until the fourteenth day. The myelosuppression severity was observed and compared between the two groups prior to chemotherapy, at the 3rd, 7th and 14th days of chemotherapy; the QOL in the two groups was evaluated before chemotherapy, at the 14th and 21st days of chemotherapy. Results: Regarding myelosuppression, the peripheral blood indicators increased significantly at the 3rd day of chemotherapy in both groups (P<0.05 or P<0.01); at the 7th and 14th days of chemotherapy, the peripheral blood indicators presented a decreasing tendency in the two groups, but the level in the observation group was still significantly higher than that before chemotherapy (P<0.01); at the 3rd, 7th and 14th days of chemotherapy, the peripheral blood indicators in the observation group were higher than those in the control group (P<0.05 or P<0.01); the occurrence rate of myelosuppression in the observation group was significantly lower than that in the control group (P<0.01). The QOL score in the observation group was markedly higher than that in the control group at the 14th and 21st days of chemotherapy (both P<0.05). Conclusion: Grain-sized moxibustion can effectively improve myelosuppression after chemotherapy for NSCLC, reducing its occurrence and enhancing the patient's QOL.

Clinical observation of the effects of moxibustion with seed-sized moxa cone plus opioid drugs on cancer pain and immune function / 针灸推拿医学（英文版）

Objective:To observe the clinical efficacy of moxibustion with seed-sized moxa cone plus opioid drugs for moderate-to-severe cancer pain, and the effect on immune function in patients with cancer pain. Methods: A total of 80 patients with moderate-to-severe cancer pain were randomized into an observation group and a control group by the random number table method, with 40 cases in each group. Both groups were treated with opioid drugs for analgesia according to the standardized management principles for cancer pain. In addition, the observation group was given moxibustion with seed-sized moxa cone. The treatment was performed once a day, continuous 5-day treatment with a 2-day interval constituted a treatment course, and a total of 2 courses were performed. The score of numerical rating scale (NRS) and 24 h equivalent morphine consumption was compared between the two groups before treatment, after 1 treatment course and after 2 courses of treatment. The immune functions were compared between the two groups before and after 2 courses of treatment. Results: During the treatment, there were 3 dropouts in the control group, and 2 dropouts in the observation group. Before the treatment, there were no significant differences in the NRS score and 24 h equivalent morphine consumption between the two groups (both P＞0.05). The NRS scores of both two groups were quite stable during the whole treatment period, and there was no significant difference in the intra-group comparison after treatment (both P＞0.05), and there was no significant difference between the two groups at the same time point (both P＞0.05). In the control group, the 24 h equivalent morphine consumption showed an increasing trend. The dosage after 1 treatment course and 2 courses of treatment was statistically different from that before treatment in the control group (both P＜0.01). There was no significant change in the mean 24 h equivalent morphine consumption in the observation group compared with that before treatment (both P＞0.05). After 2 courses of treatment, the 24 h equivalent morphine consumption in the observation group was significantly lower than that in the control group at the same time point (P＜0.05). Before treatment, there was no significant difference in the levels of T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) between the two groups (all P＞0.05). After treatment, the levels of T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) in the control group were lower than those before treatment (all P＜0.05), while the levels in the observation group were higher than those before treatment, and the levels of CD3+ and CD4+ were significantly different from those before treatment (both P＜0.05). After treatment, the levels of T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) of the observation group were significantly higher than those of the control group at the same time point (all P＜0.05). Conclusion: Moxibustion with seed-sized moxa cone can reduce the dosage of opioid drugs used in patients with moderate-to-severe cancer pain and improve their immune functions.

Three-dimensional printing beta-tricalcium phosphate scaffold loaded with icariin particles for repairing osteonecrosis of the femoral head in rabbits / 中国组织工程研究

BACKGROUND: Preliminary study has prepared three-dimensional printing β-tricalcium phosphate scaffold loaded with icariin. OBJECTIVE: To investigate the role of three-dimensional printing β-tricalcium phosphate scaffold loaded with icariin in the repair of rabbit models of osteonecrosis of the femoral head. METHODS: New Zealand white rabbits (provided by Qinglongshan Laboratory Animal Center of Nanjing) were selected to establish the steroid-induced osteonecrosis of the femoral head. The 27 model rabbits underwent core decompression and debridement, were randomly divided into three groups, and then implanted with autologous bone, β-tricalcium phosphate scaffold, three-dimensional printing β-tricalcium phosphate scaffold loaded with icariin (composite scaffold group) , respectively. The micro-CT scanning and pathological observation were performed at 4, 8, and 12 weeks after implantation. RESULTS AND CONCLUSION: (1) Micro-CT showed that at 4 weeks after implantation, trabecular bone was observed around and in implants in each group. In the autologous bone group, there were a large number of trabecular bones in the grafting area at 8 weeks, and the trabecular bone structure was dense at 12 weeks after implantation. In the tricalcium phosphate and composite scaffold groups, the scaffolds were well integrated with the bone interface. At 4 weeks after implantation, there was a certain amount of trabecular bone surrounding the scaffold, and trabecular grew into the scaffold until 8 weeks in the composite scaffold group. At 4 weeks after implantation, few thin trabecular bone was visible, and extensive trabecular bone formation was observed around the scaffold at 8 weeks in the tricalcium phosphate group. (2) Hematoxylin-eosin staining results showed that there were many mature osteoblasts, and few cartilage matrix, newly born bones integrated well to the implants at 12 weeks in the autologous bone and tricalcium phosphate groups. In the composite scaffold group, there were many cartilage matrixes, and newly born bones integrated poorly to the implants. (3) Masson staining showed that at 12 weeks after implantation, the osteogenic capacity in the composite scaffold group was lower than that in the autologous bone group (P < 0.05) , but higher than that in the tricalcium phosphate group (P < 0.05) . (4) TRAP staining results at 12 weeks after implantation revealed that the amount of osteoclast in composite scaffold group was less than that in the tricalcium phosphate group (P < 0.05) , and was not significantly different from the autologous bone group (P> 0.05) . (5) Immunohistochemical staining at 12 weeks after implantation revealed that the positive rate of vascular endothelial growth factor in the composite scaffold group was higher than that in the tricalcium phosphate group (P < 0.05) , and lower than that in the autologous bone group (P < 0.05) . (6) In summary, three-dimensional printing β-tricalcium phosphate scaffold loaded with icariin implanted into the rabbit model of osteonecrosis of the femoral head can promote the proliferation and differentiation of osteoblasts, inhibit the viability of osteoclasts, promote the angiogenesis, and contribute to the repair of osteonecrosis of the femoral head in rabbits.

Traditional Chinese medicine education in Canada / 中国结合医学杂志

The history of education and legislation of traditional Chinese medicine (TCM) and acupuncture in Canada is short. The first school of TCM opened its door to the general public in Canada in 1985 and the first legislation of acupuncture was introduced in Alberta, Canada in 1988. Currently, TCM and/or acupuncture have been regulated in five provinces in Canada. The legislation and regulation, as well as education of TCM and acupuncture vary among the five provinces in Canada. Opportunities and challenges facing TCM education exist simultaneously. Strategies are proposed to develop an international standard for TCM education in Canada, and possibly in other English speaking countries as well.
