| 1 | Characteristics of climatic trends and correlation between pan-evaporation and environmental factors in the last 40 years over China显示文摘Using the data observed by 62 Chinese Routine Meteorological Stations (CRMS) with long term radiation observation, the climatic trends and the relationship between pan-evaporation and its environmental factors are analyzed comprehensively. The results show that during the last 40 years, the relative humidity is uptrend in west China, downtrend in east China, and their extrema are 0.20%/a and ?0.22%/a respectively; the precipitations of about 61% CRMS keep uptrend, its maximum can reach 10.52 mm/a2 while the cloud amounts of about 79% CRMS keep downtrend slightly. About 98% CRMS display the air temperature uptrend, and the maximum is 0.11℃/a. About 76% CRMS display the land surface temperature uptrend. About 87% CRMS show the daily range of temperature downtrend. The global radiations observed by about 85% CRMS and the 10 m wind speeds observed by about 77% CRMS hold downtrend. The annual pan-evaporations of about 66% CRMS hold descend trend, and the biggest descent reaches ?24.9 mm/a2. The pan-evaporation has good relationship with many environmental factors, but the relationship with the relative humidity is the best. All of the climatic trends respond to the global climate changes. | ZUOHongchao LIDongliang HUYinqiao BAOYan LüShihua | 2005 | Chinese Science Bulletin2005，50，12： | 37 |

| 3 | Prognostic nutritional index is an independent prognostic factor for gastric cancer patients with peritoneal dissemination显示文摘Objective: The predictive and prognostic role of prognostic nutritional index(PNI) in gastric cancer patients with peritoneal dissemination remains unclear. This study aims to explore the role of the PNI in predicting outcomes of gastric cancer patients with peritoneal dissemination.Methods: A total of 660 patients diagnosed with gastric adenocarcinoma with peritoneal metastasis between January 2000 and April 2014 at Sun Yat-sen University Cancer Center and the Sixth Affiliated Hospital of Sun Yatsen University were retrospectively analyzed. The clinicopathologic characteristics and clinical outcomes of patients with peritoneal dissemination were analyzed.Results: Compared with PNI-high group, PNI-low group was correlated with advanced age(P=0.036), worse performance status(P<0.001), higher frequency of ascites(P<0.001) and higher frequency of multisite distant metastasis(P<0.001). Kaplan-Meier survival curves showed that PNI-high group had a significantly longer median overall survival than PNI-low group(13.13 vs. 9.03 months, P<0.001). Multivariate survival analysis revealed that Borrmann type IV(P=0.014), presence of ascites(P=0.017) and lower PNI(P=0.041) were independent poor prognostic factors, and palliative surgery(P<0.001) and first-line chemotherapy(P<0.001) were good prognostic factors. For patients receiving palliative surgery, the postoperative morbidity rates in the PNI-low group and PNIhigh group were 9.1% and 9.9%, respectively(P=0.797). The postoperative mortality rate was not significantly different between PNI-low and PNI-high groups(2.3% vs. 0.9%, P=0.362).Conclusions: PNI is a useful and practical tool for evaluating the nutritional status of gastric cancer patients with peritoneal dissemination, and is an independent prognostic factor for these patients. | Runcong Nie Shuqiang Yuan Shi Chen Xiaojiang Chen Yongming Chen Baoyan Zhu Haibo Qiu Zhiwei Zhou Junsheng Peng Yingbo Chen | 2016 | Chinese Journal of Cancer Research2016，28，6： | 19 |

| 5 | Comparsion analysis of data mining models applied to clinical research in Traditional Chinese Medicine显示文摘OBJECTIVE: To help researchers selecting appropriate data mining models to provide better evidence for the clinical practice of Traditional Chinese Medicine(TCM) diagnosis and therapy.METHODS: Clinical issues based on data mining models were comprehensively summarized from four significant elements of the clinical studies:symptoms, symptom patterns, herbs, and efficacy.Existing problems were further generalized to determine the relevant factors of the performance of data mining models, e.g. data type, samples, parameters, variable labels. Combining these relevant factors, the TCM clinical data features were compared with regards to statistical characters and informatics properties. Data models were compared simultaneously from the view of applied conditions and suitable scopes.RESULTS: The main application problems were the inconsistent data type and the small samples for the used data mining models, which caused the inappropriate results, even the mistake results. These features, i.e. advantages, disadvantages, satisfied data types, tasks of data mining, and the TCM issues, were summarized and compared.CONCLUSION: By aiming at the special features of different data mining models, the clinical doctors could select the suitable data mining models to resolve the TCM problem. | Yufeng Zhao Qi Xie Liyun He Baoyan Liu Kun Li Xiang Zhang Wenjing Bai Lin Luo Xianghong Jing Ruili Huo | 2014 | Journal of Traditional Chinese Medicine2014，34，5： | 14 |

| 8 | Efficacy evaluation of summer acupoint application treatment on asthma patients: a two-year follow-up clinical study显示文摘OBJECTIVE: To evaluate the self-efficacy and satisfaction of asthma patients subjected to summer acupoint application treatment(SAAT).METHODS: A two-year follow-up clinical study was conducted. Patients with asthma were treated by applying a herbal paste onto the Feishu(BL 13) and Fengmen(BL 12) acupoints on the three hottest days of summer, according to the traditional Chinese calendar, from 2008 to 2010. During a two-year follow-up, these patients were asked tofill out a questionnaire evaluating asthma degree,exacerbation frequency, concomitant medications and self-satisfaction. The self-rate and doctor-report outcomes obtained in parallel were evaluated to assess the efficacy of SAAT.RESULTS: A total of 527 asthma patients were initially enrolled in this study, of which 97 elderly patients and those with more severe cases of asthma were lost to follow-up. Thus, a total of 430 patients were valid for analysis using self-rate data. Nevertheless, occasional negative returns were obtained;almost all of the outcomes were rated as 'No change', 'Moderate effective', or 'Very effective'. In addition, 80% of the patients were satisfied with this treatment. Moreover, 391(91.4%) patients were somewhat improved after SAAT in 2009, and further improvement was observed in 2010. After SAAT, the average asthma-degree score decreased from 5.3 in 2008 to 4 in 2009 and, subsequently to3.5 in 2010.CONCLUSION: With pronounced patient satisfaction, SAAT can reduce the exacerbation severity and frequency, concomitant medications and asthma degree. Prolonging the treatment course might enhance the efficacy of SAAT. | Wu Xiaqiu Peng Jin Li Guoqin Zhang Wei Liu Guangxia Liu Baoyan | 2015 | Journal of Traditional Chinese Medicine2015，35，1： | 7 |
| 9 | Influencing factors on efficacy of summer acupoint application treatment for allergic rhinitis:a retrospective study显示文摘OBJECTIVE:Allergic rhinitis(AR) is a common health problem.Summer acupoint application treatment(SAAT) is reported to effectively treat and prevent AR from seasonal onset.In the present study,we aimed to evaluate its effects,especially on the course of AR,through a retrospective study.METHOD:A cross-sectional multicenter study was performed based on patients treated between 2008 and 2009 in 13 clinical centers in China.A total of 1058 outpatients aged ≥2 years with documented AR and ≥1 year SAAT were eligible for enrollment.A case report form(CRF) was completed by both patient and doctor.The CRF was designed to collect data on the patient's history of SAAT,AR condition,and self-reported health condition.The outcomes(dependent variables) were incidence and intensity of AR and concomitant medications used.Data were analyzed with ordinal logistic regression(OLR).RESULTS:Treatment course and seasonal pattern of AR were related to all dependent variables positively.After controlling for sample bias and confounding factors,the findings suggested that a 3-year treatment course had better efficacy(OR/incidence of AR:2.57,95%CI:1.76-3.76;OR/intensity of AR:2.17,95%CI:1.50-3.17;OR/concomitant medications:2.20,95% CI:1.50-3.23) compared with a 2-year or less treatment course.CONCLUSION:The results showed that:1)the length of treatment course was positively associated with the efficacy of SAAT(the longer the treatment course,the better the efficacy);and 2)SAAT was more efficacious in treating seasonal AR than non-seasonal AR. | Jin Peng Xiaqiu Wu Jingqing Hu Yigong Fang Mingjie Zi Baoyan Liu | 2012 | Journal of Traditional Chinese Medicine2012，32，3： | 7 |

| 11 | Clinical features and the traditional Chinese medicine therapeutic characteristics of 293 COVID-19 inpatient cases显示文摘Coronavirus disease 2019 (COVID-19) is now pandemic worldwide and has heavily overloaded hospitals in Wuhan City, China during the time between late January and February. We reported the clinical features and therapeutic characteristics of moderate COVID-19 cases in Wuhan that were treated via the integration of traditional Chinese medicine (TCM) and Western medicine. We collected electronic medical record (EMR) data, which included the full clinical profiles of patients, from a designated TCM hospital in Wuhan. The structured data of symptoms and drugs from admission notes were obtained through an information extraction process. Other key clinical entities were also confirmed and normalized to obtain information on the diagnosis, clinical treatments, laboratory tests, and outcomes of the patients. A total of 293 COVID-19 inpatient cases, including 207 moderate and 86 (29.3%) severe cases, were included in our research. Among these cases, 238 were discharged, 31 were transferred, and 24 (all severe cases) died in the hospital. Our COVID-19 cases involved elderly patients with advanced ages (57 years on average) and high comorbidity rates (61%). Our results reconfirmed several well-recognized risk factors, such as age, gender (male), and comorbidities, as well as provided novel laboratory indications (e.g., cholesterol) and TCM-specific phenotype markers (e.g., dull tongue) that were relevant to COVID-19 infections and prognosis. In addition to antiviral/antibiotics and standard supportive therapies, TCM herbal prescriptions incorporating 290 distinct herbs were used in 273 (93%) cases. The cases that received TCM treatment had lower death rates than those that did not receive TCM treatment (17/273= 6.2% vs. 7/20= 35%, P = 0.0004 for all cases;17/77= 22% vs. 7/9= 77.7%, P = 0.002 for severe cases). The TCM herbal prescriptions used for the treatment of COVID-19 infections mainly consisted of Pericarpium Citri Reticulatae, Radix Scutellariae, Rhizoma Pinellia, and their combinations, which reflected the practical TCM principles (e.g., clearing heat and dampening phlegm). Lastly, 59% of the patients received treatment, including antiviral, antibiotics, and Chinese patent medicine, before admission. This situation might have some effects on symptoms, such as fever and dry cough. By using EMR data, we described the clinical features and therapeutic characteristics of 293 COVID-19 cases treated via the integration of TCM herbal prescriptions and Western medicine. Clinical manifestations and treatments before admission and in the hospital were investigated. Our results preliminarily showed the potential effectiveness of TCM herbal prescriptions and their regularities in COVID-19 treatment. | Zixin Shu Yana Zhou Kai Chang Jifen Liu Xiaojun Min Qing Zhang Jing Sun Yajuan Xiong Qunsheng Zou Qiguang Zheng Jinghui Ji Josiah Poon Baoyan Liu Xuezhong Zhou Xiaodong Li | 2020 | Frontiers of Medicine2020，14，6： | 7 |

| 13 | Co-Production of Lipids, Eicosapentaenoic Acid, Fucoxanthin, and Chrysolaminarin by Phaeodactylum tricornutum Cultured in a Flat-Plate Photobioreactor Under Varying Nitrogen Conditions显示文摘The marine diatom Phaeodactylum tricornutum is a polymorphological, ecologically significant, and well-studied model of unicellular microalga. This diatom can accumulate diverse important metabolites. Herein, we cultured P. tricornutum in an internally installed tie-piece flat-plate photobioreactor under 14.5 m mol L^(-1)(high nitrogen, HN) and 2.9 m mol L^(-1)(low nitrogen, LN) of KNO_3 and assessed its time-resolved changes in biochemical compositions. The results showed that HN was inductive to accumulate high biomass(4.1 g L^(-1)). However, the LN condition could accelerate lipid accumulation in P. tricornutum. The maximum total lipid(TL) content under LN was up to 42.5% of biomass on day 12. Finally, neutral lipids(NLs) were 63.8% and 75.7% of TLs under HN and LN, respectively. The content of EPA ranged from 2.3% to 1.5% of dry weight during the growth period under the two culture conditions. Peak volumetric lipid productivity of 128.4 mg L^(-1)d^(-1) was achieved in the HN group(on day 9). The highest volumetric productivity values of EPA, chrysolaminarin, and fucoxanthin were obtained in the exponential phase(on day 6) under HN, which were 9.6, 93.6, and 4.7 mg L^(-1)d^(-1), respectively. In conclusion, extractable amounts of lipids, EPA, fucoxanthin, and chrysolaminarin could be obtained from P. tricornutum by regulating the culture conditions. | GAO Baoyan CHEN Ailing ZHANG Wenyuan LI Aifen ZHANG Chengwu | 2017 | Journal of Ocean University of China2017，16，5： | 6 |

| 18 | Estimation of correction coefficients for measured coal bed methane contents显示文摘Improving the accuracy and precision of coal bed methane(CBM) estimates requires correction of older data from older coal exploration surveys to newer standards.Three methods,the depth gradient method,the contour aerial weight method,and the well-point aerial weight method,were used to estimate the correction coefficient required to predict CBM gas content from coal exploration data.The data from the Nos.3 and 15 coal seams provided the coal exploration data while the CBM exploration stages within the X1 well block located in the southern part of the Qinshui Basin provided the data obtained using newer standards.The results show the correction coefficients obtained from the two aerial weight methods are similar in value but lower than the one obtained from the depth gradient method.The three methods provide similar results for the Nos.3 and 15 seams in that the correction factor is lower for the former seam.The results from the depth gradient method taken together with the coal seam burial depth and the coal rank suggest that variations in the correction factor increase linearly along with coal seam burial depth and coal rank.The correlation obtained can be applied to exploration and the evaluation of coal bed gas resources located in coalfields. | Lei Bo Fu Xuehai Zhou Baoyan Shen Jia ZOU Mingjun Feng Qing | 2012 | International Journal of Mining Science and Technology2012，22，4： | 5 |
| 19 | Hybrid Ti_2AlC Bonded Diamond Composites Prepared by a Self-propagation Sintering Approach显示文摘Ti, Al, graphite and diamond powders were used as raw materials to prepare Ti_2AlC matrixbonded diamond composite using self-propagating high-temperature synthesis(SHS) method. The effect of diamond size and content on the fabrication of Ti_2AlC-bonded diamond material was investigated. Results showed that Ti_2AlC matrix-bonded diamond composites could be obtained by SHS. The phase composition and microstructure of the Ti_2AlC-bonded diamond material were influenced by the diamond content and size. When the diamond(93 μm) additive amounts were 10% and 20%, the product phases included Ti_2AlC, TiC and Al_3Ti. However, excess Ti and Al persisted in the sample that contained 30% diamond. Diamond bonded well with the matrix in the sample that contained 10% diamond. Moreover, addition of coarse diamond particles with sizes of 93 and 125 μm produced a mainly Ti_2AlC matrix. However, diamond adequately reacted with Ti to form TiC when finer diamond particles(5 and 10 μm) were used. | 张旺玺 LIANG Baoyan LUO Wei WANG Yanzhi | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，1： | 4 |
