Background The outbreak of Coronavirus disease 2019 (COVID-19) has caused more than 180 million infections and 3.9 million deaths. To date, emerging clinical evidence has shown the synergetic benefits of Chinese herbal injections in treating this contagious respiratory disease. This review aims to summarize and analyze the efficacy and safety of Chinese herbal injections in the therapy of COVID-19. Methods The literature from 3 electronic databases, PubMed, CNKI, and Web of Science, were searched using the search terms “COVID-19”, “SARS-CoV-2”, “traditional Chinese medicine”, “herb”, “herbal”, and “injection”. Then the identified articles were comprehensively evaluated. Results Limited data demonstrated that Chinese herbal injections could significantly improve the clinical outcomes of COVID-19 patients, especially in combination with conventional treatment strategies. The benefits of which were mainly associated with the relief of symptoms, prevention of secondary infection, regulation of inflammation and immune function. There was also evidence showing the inhibitory effects on SARS-CoV-2 replication in vitro. Nevertheless, available real-world data suggested the increased risk of adverse event. Furthermore, the defects of existing researches and the insights for discovering novel antiviral drugs were prospectively discussed. Conclusion Evidence-based advances revealed that Chinese herbal injections such as XueBiJing injection and ShenMai injection, exerted potent effects against COVID-19. Further laboratory researches and clinical evaluation are needed to gather scientific evidence on the efficacy and safety.

Prognostic Value of Vascular Endothelial Growth Factor Expression in Resected Gastric Cancer

Liu, Lei,Ma, Xue-Lei,Xiao, Zhi-Lan,Li, Mei,Cheng, Si-Hang,Wei, Yu-Quan Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.7

Background and Aims: Vascular endothelial growth factor (VEGF) is a potential prognostic biomarker for patients with resected gastric cancer. However, its role remains controversial. The objective of this study was to conduct a systematic review and meta-analysis of published literature. Methods: Relevant literature was identified using Medline and survival data from published studies were collected following a methodological assessment. Quality assessment of eligible studies and meta-analysis of hazard ratio (HR) were performed to review the correlation of VEGF overexpression with survival and recurrence in patients with gastric cancer. Results: Our meta-analysis included 44 published studies with 4,794 resected patients. VEGF subtype for the prediction of overall survival (OS) included tissue VEGF (HR=2.13, 95% CI 1.71-2.65), circulating VEGF (HR=4.22, 95% CI 2.47-7.18), tissue VEGF-C (HR=2.21, 95% CI 1.58-3.09), tissue VEGF-D (HR=1.73, 95% CI 1.25-2.40). Subgroup analysis showed that HRs of tissue VEGF for OS were, 1.78 (95% CI 0.90-3.51) and 2.31 (95% CI 1.82-2.93) in non-Asians and Asians, respectively. The meta-analysis was also conducted for disease free survival (DFS) and disease specific survival (DSS). Conclusion: Positive expression of tissue VEGF, circulating VEGF, VEGF-C and VEGF-D were all associated with poor prognosis in resected gastric cancer. However, VEGF demonstrated no significant prognostic value for non-Asian populations. Circulating VEGF may be better than tissue VEGF in predicting prognosis.

吴昌硕篆书创作小考

刘磊磊(Lei-Lei Liu),袁暁鹏(Xiao-Peng Yuan) 한국서예학회 2023 서예학연구 Vol.42 No.-

오창석(吴昌硕)의 전서는 필법, 구성, 장법, 묵법, 필법 등의 기법이 선인과 판이하게 다른데, 전서의 새로운 모습을 만들어내는 데 성공하여 큰 성과를 거둔 배경에는 여러 가지 이유가 있을 것이다. 우선 비파(碑派)서법의 서학사상을 흡수하여 금석(金石)을 취하고 고풍스럽고 웅장한 예술양식을 추앙하였다. 둘째, 등석여(邓石如), 양기손(杨沂孙) 등의 명가를 충분히 학습하는 기초 위에서 ≪석고문(石鼓文)≫을 주요 법으로 삼는 동시에 다양한 서체를 참고하여 여러 예술을 융합하고 자신의 예술 실천을 지속적으로 풍부하게 한다. 특히, 개인 특색 있는 필기구를 사용하여 개인 스타일을 지속적으로 강화합니다. 수십 년의 노력을 통해 마침내 ‘이리(二李)’ 전서 외에 다른 필법을 개척하고 전서 예술의 또 다른 정점을 창조하여 후대의 서예 예술 발전에 심대한 영향을 미쳤습니다. Wu Changshuo's seal book is very different from its predecessors in the use of pen, structure, sealing, ink, writing rhythm and other techniques, successfully shaping the new face of seal writing, and achieving great achievements, the reasons behind it should be many, first of all, he absorbed the calligraphy ideas of the stele calligraphy, took the golden stone, and advocated the simple and strong artistic style. Secondly, on the basis of fully learning from famous artists such as Deng Shiru(邓石如) and Yang Yisun(杨沂孙), he took “Shiguwen”(石鼓文) as the main object, and at the same time drew on a variety of book styles, integrated multiple arts, and constantly enriched his artistic practice. Third, use a very personal writing instrument to constantly strengthen your personal style. Through decades of hard work, it finally opened up another way outside the “Er Li” seal book, creating another peak of seal book art, which had a far-reaching impact on the development of calligraphy art in later generations. 吴昌硕的篆书在用笔、结构、章法、墨法、书写节奏等技法上都迥异于前人,成功地塑造了篆书的新面貌,取得了巨大的成就,其背后的原因应该是多方面的,首先,他吸收了碑派书法的书学思想,取法金石,推崇古朴雄强的艺术风格。其次,在充分学习邓石如、杨沂孙等名家的基础上,以≪石鼓文≫为主要取法对象,同时借鉴多种书体,融合多门艺术,不断丰富自己的艺术实践。再次,采用极具个人特色的书写工具,不断强化个人风格。通过几十年的努力,最终于“二李”篆书之外另辟蹊径,创造了篆书艺术的又一座高峰,对后世书法艺术的发展产生了深远的影响。

Yan, Jian,Liu, Xiao-Long,Han, Lu-Zhe,Xiao, Gang,Li, Ning-Lei,Deng, Yi-Nan,Yin, Liang-Chun,Ling, Li-Juan,Yu, Xiao-Yuan,Tan, Can-Liang,Huang, Xiao-Ping,Liu, Li-Xin Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.2

The aim of the present study was to investigate the expression of the transcription factor Ki-67, ER, PR, Her2/neu, p21, EGFR, and TOP II-${\alpha}$ in the tumor tissue of patients with invasive ductal carcinoma(IDC); in addition, we examined correlations between these markers. Two hundred and sixteen IDC patients, who were not previously been treated with chemo- or radiotherapy, were included in the study. All tumors were grade I-III. Expression of molecular markers was determined by immunohistochemical analysis on paraffin-embedded tissue sections. Follow-up data were collected for 3 months to 10 years and analyzed for tumor recurrence, survival time, and prognostic risk factors. We determined Ki-67 expression correlates with the expression of ER, PR, HER-2, EGFR, and TOP-${\alpha}$, as well as lymph node involvement, high tumor grade, lymphovascular invasion, high tumor stage, and high TNM stage in IDC. Positive Ki-67 expression was a risk factor for rapid tumor recurrence and may help tumor progression, leading to poor prognosis in IDC. Ki-67 was directly correlated with EGFR, TOP II-${\alpha}$, lymph node involvement, high tumor grade, lymphovascular invasion, high tumor stage, and high TNM stage in the hormone receptor subtypes of breast cancer. In triple negative breast cancer, Ki-67 correlated with TOP II-${\alpha}$. Expression of Ki-67 correlated with that of ER, PR, HER-2, EGFR, TOP II-${\alpha}$, and p21. In addition, the biomarker Ki-67 has a role as a prognostic factor and indicates a poor prognosis in IDC.

Ma, Xue-Lei,Xiao, Zhi-Lan,Liu, Lei,Liu, Xiao-Xiao,Nie, Wen,Li, Ping,Chen, Nian-Yong,Wei, Yu-Quan Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.4

Introduction: Recent studies have shown that circulating tumor cells (CTCs) play potential roles as diagnostic and prognostic biomarkers with various cancer types. The aim of this study was to comprehensively and quantitatively summarize the evidence for the use of CTCs to predict the survival outcome of lung cancer patients. Materials and Methods: Relevant literature was identified using Medline and EMBASE. Patients' clinical characteristics, overall survival (OS) and progression-free survival (PFS) together with CTC positive rates at different time points (before, during and after treatment) were extracted. A meta-analysis was performed to clarify the prognostic role of CTCs and the correlation between the CTC appearance and clinical characteristics. Results: A total of 12 articles containing survival outcomes and clinical characteristics and 15 articles containing only clinical characteristics were included for the global meta-analysis. The hazard ratio (HR) for OS predicted by pro-treatment CTCs was 2.61 [1.82, 3.74], while the HR for PFS was 2.37 [1.41, 3.99]. The HR for OS predicted by post-treatment CTCs was 4.19 [2.92, 6.00], while the HR for PFS was 4.97 [3.05, 8.11]. Subgroup analyses were conducted according to histological classification and detection method. Odds ratio (OR) showed the appearance of pro-treatment CTCs correlated with the lymph node status, distant metastasis, and TNM staging, while post-treatment CTCs correlated with TNM staging only. Conclusion: Detection of CTCs in the peripheral blood indicates a poor prognosis in patients with lung cancer.

Ma, Xue-Lei,Liu, Lei,Liu, Xiao-Xiao,Li, Yun,Deng, Lei,Xiao, Zhi-Lan,Liu, Yan-Tong,Shi, Hua-Shan,Wei, Yu-Quan Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.5

Introduction: Many studies have reported that microRNA-21 (miR-21) mihght predict the survival outcome in non-small cell lung cancers (NSCLCs) but the opposite opinion has also been expressed. The aim of this study was to summarize the evidence for a prognostic role of miR-21. Materials and Methods: All the eligible studies was searched by Medline and EMBASE and patients' clinical characteristics and survival outcome were extracted. Then a meta-analysis was performed to clarify the prognostic role of the miR-21 expression in different subgroups. Results: A total of 8 eligible articles were yielded covering survival outcomes or clinical characteristics. The combined hazard ratio (HR) and 95% confidence interval (95% CI) for overall survival (OS) was 2.19 [0.76, 6.30], while the combined HR (95% CI) of Asian group for OS had a significant result, 5.49 [2.46, 12.27]. The combined HR (95% CI) for recurrence free survival or disease free survival (RFS/DFS) was 2.31 [1.52, 3.49]. Odds ratios (ORs) showed that the miR-21 expression was associated with lymph node status and histological type. Conclusion: miR-21 expression could predict the prognostic outcome of NSCLC in Asians, despite some deficiencies in the study data.

Background There are several effective complementary and integrative therapies for patients with severe COVID-19. The trial aims to evaluate the efficacy and advantages of the qigong exercise and acupressure rehabilitation program (QARP) for treating patients with severe COVID-19. Methods A total of 128 patients with COVID-19 aged 20 to 80 years were recruited and randomly allocated in a 1:1 ratio to receive QARP plus standard therapies or standard therapies alone. QARP consisted of acupressure therapy and qigong exercise (Liu Zi Jue). The primary outcome was measured with the modified Medical Research Council (mMRC) dyspnea scale, and the secondary outcomes included the modified Borg dyspnea scale (MBS), fatigue Scale-14 (FS-14), patient health questionnaire-9 scale (PHQ-9), duration of respiratory symptoms, and vital signs. Results In total, 128 patients completed the clinical trial. The QARP group and standard therapies group showed significant improvements in vital signs (except blood pressure) and clinical scales compared with baseline (p<0.05). The QARP group also showed more significant improvement in the mMRC dyspnea scale (-1.8 [-2.1, -1.6], p=0.018) and modified Borg dyspnea scale (-3.7 [95% confidence intervals (CI) -4.3, -3.1], p=0.045). The duration of cough was 14.3 days (95% CI 12.6, 16.1, p=0.046), and the length of hospital stay was 18.5 days (95% CI 17.0, 20.0, p=0.042) in the QARP group, both of which were significantly reduced compared with the standard therapies group (p<0.05). Conclusion QARP plus standard therapies improved lung function and symptoms such as dyspnea and cough in patients with severe COVID-19 and shortened the length of hospital stay. Therefore, QARP may be considered an effective treatment option for patients with severe COVID-19.

Background/Aims There are increasing evidences for gastrointestinal motility disorder (GIMD) and gastric stress ulcer induced by noise stress. The present study was to investigate the reversed effect of melatonin on GIMD and gastric stress ulcer induced by noise stress and potential mechanism. Methods Noise stress was induced on rats, and melatonin (15 mg/kg) was administered to rats by intraperitoneal injection. Differences were assessed in gastric residual rate (GRR), small intestine propulsion rate (SPR), Guth injury score, cortisol, gastrointestinal hormones (calcitonin-gene-related peptide and motilin) and oxidative stress markers (superoxide dismutase and malondialde hyde) in blood plasma as well as gastric mucosa homogenate with or without melatonin. The pathological examination of gastric mucosa was also performed. Results The GRR and SPR were improved by noise stress compared with control (P < 0.05). The pathological examination and Guth injury score revealed gastric stress ulcer. Moreover, the levels of cortisol, motilin and malondialdehyde in blood plasma and malondialdehyde in gastric mucosa homogenate were increased by noise stress (P < 0.05). CGRP and superoxide dismutase activity in both of blood plasma and gastric mucosa homogenate were significantly decreased (P< 0.05). Furthermore, melatonin reversed changes in GRR, SPR, pathological examination, Guth injury score, cortisol, motilin, CGRP, superoxide dismutase activity and malondialdehyde (P < 0.05). Conclusions Melatonin is effective in reversing the GIMD and gastric stress ulcer induced by noise stress. The underlying mechanism may be involved in oxidative stress and gastrointestinal hormones.

Diabetic nephropathy (DN) is an important diabetic complication, and podocyte apoptosis plays a critical role in the development of DN. In the present study, we examined the preventive effect of the total flavone glycosides of Flos Abelmoschus manihot (TFA) on urinary microalbumin and glomerular podocyte apoptosis in experimental DN rats. The preliminary oral administration of TFA (200 mg/kg/day) for 24 weeks significantly decreased the urinary microalbumin to creatinine ratio and 24-h urinary total protein in streptozotocin-induced DN rats. Terminal deoxynucleotidyl transferasemediated dUTP nick end-labeling assay indicated glomerular cell apoptosis in DN rats was significantly improved by pretreatment with TFA. Furthermore, fluorescence-activated cell sorting and Hoechst 33342 staining suggested preincubation with hyperoside (50 and 200 lg/mL), the major active constituent of TFA, could significantly mitigate cultured podocyte apoptosis induced by the advanced glycation end-products (AGEs). Western blot analysis showed that increased caspase-3 and caspase-8 expressions induced by AGEs were also inhibited by pretreatment with hyperoside at both doses. Our results demonstrate that TFA pretreatment can decrease urinary albumin excretion in early-stage DN, which might be accomplished by preventing renal damage and podocyte apoptosis.
