Based on the traditional Chinese Medicine's perspective, this manuscript systematically reviewed the characteristics of medicinal fungi, medicinal value of fungi, and the history of application for health-care in China. According to their natural attributes, traditional Chinese medicine could be classified into four categories: plant medicines, fungi medicines, animal medicines and mineral medicines. As research continues, the medical fungi and its application will be a promising new field in traditional Chinese medicine based on. Our present review has provided new insight on medical fungi and traditional Chinese medicine.

This paper reviewed characteristics of inonotus obliquus, and progress in medical research regarding inonotus obliquus in Russia. To be specific, we summarized morphological characteristics, distribution, growing conditions, history of application, active ingredients, and mechanism of actions of inonotus obliquus in this review, and illustrated specific notes for its potential medicinal value and health benefits. Our manuscript has provided new insight for further research and application of inonotus obliquus in China.

In this paper, we reviewed the findings from previous studies on the anti-tumor efficacy of inonotus obliquus, one of the most famous edible and medical fungi, in Russia and the former Soviet Union since the 1950s. To be specific, the findings from clinical researches regarding the medicinal benefits of inonotus obliquus for treating gastric cancer, esophageal cancer, lung cancer, laryngeal cancer, breast cancer, and leukemia have been summarized, indicating inonotus obliquus may relieve symptoms, improve immune and neural function, improve life quality, and may prolong survival in the cancer patients.

This paper summarized the anti-tumor experimental researches of inonotus obliquus in Russia and former Soviet Union.Since the 1950s,a series of experimental studies of Inonotus obliquus have been carried out in Russia and the Soviet Union based on prior clinical studies to further explore its anti-tumor effects and mechanisms.The effects of Inonotus obliquus were inhibiting the growth and metastasis of tumors,and its specific mechanisms might be involving regulation of cancer cell dynamic phenotypes.

According to the literatures of the former Soviet Union and Russia about inonotus obliquus (commonly known as chaga),and the research progress in the past 20 years in China,and the author's 30-year experience on inonotus obliquus' clinical application,and the records of medicinal properties of birch in ancient China literatures,the potential effect of inonotus obliquus is analyzed according to traditional Chinese medicine theory.It is believed that the taste of inonotus obliquus is slightly bitter and cold.The main effect of inonotus obliquus is strengthening the body resistance,the specific benefits of which include nourishing qi,nourishing blood,nourishingyin,tonifying spleen,invigorating the spleen and stomach,nourishing liver,tonifying kidney and nourish the heart and calm the nerves.The effect of inonotus obliquus also includes eliminate evil (pathogenic factors),with clearing heat and detoxicating,soothing liver and relieving stagnation,and promoting blood circulation and resolving hard lump.

According to the literatures pertaining inonotus obliquus (commonly known as chaga) documented in Russia and the former Soviet Union, the research progress of inonotus obliquus since the 1950s in Russia and the former Soviet Union and latest research progress made over the last two decades in China, , the authors further elaborated potential effects and benefits of inonotus obliquus from the perspective of traditional Chinese medicine (TCM) based on prior understanding of Flavor Effect of Inonotus obliquus. It is believed that Inonotus obliquus can benefit the five internal organs, invigorating the circulation of qi, blood, and nutriment, and thus may improve the body's adaptability and self-protection when exposing to pathogenic factors. The mechanisms of the multiple effects of Inonotus obliquus have the characteristics of multi-component, multi-target, multi-system, and multi-pathway. Inonotus obliquus can be considered to be used as both TCM medication and TCM dietary supplement.

Objective To investigate the accuracy of sequential organ failure assessment (SOFA) scoring in emergency physicians in Beijing. Methods Emergency physicians from 8 hospitals in Beijing in January 2018 were demanded to complete a SOFA questionnaire which was developed on ''wenjuanxing'' website and submit via cell phone. All participants were divided into urban center group (UC group) and no-urban center group (NUC group) based on the hospital's location. The accuracy rate of components and total score of SOFA along with the mistakes were evaluated, and the results of the two groups were compared. Results ① The questionnaire was sent to 217 emergency physicians of the 8 hospitals, and 197 qualified questionnaires were received with 109 of NUC group and 88 of UC group, respectively, the total response rate was 90.8%. Compared with those from NUC group, UC physicians had older ages [years:37 (32, 42) vs. 34 (29, 40), Z = -2.554, P = 0.011] and higher education level [postgraduate degree 76.1% (67/88) vs. 40.4% (44/109), χ2= 25.327, P < 0.001], and more of them experienced SOFA scoring [62.5% (55/88) vs. 45.9% (50/109), χ2= 5.409, P = 0.020]. Other baseline characteristics such as gender, working years, professional title and training experience were not different between the two groups. ② The accuracy rate of total SOFA score was 62.4% (123/197) in the whole cohort, and UC group was lower than that of NUC group, but the difference was not significant [56.8% (50/88) vs. 67.0% (73/109), χ2= 2.141, P = 0.143]. While comparing the accuracy of individual variable/system of SOFA, the accuracy rate of norepinephrine of UC group was much higher than NUC group [80.7% (71/88) vs. 66.1% (72/109), χ2= 5.235, P = 0.022], but the accuracy of Glasgow coma scale (GCS) was much lower in NUC group [38.6% (27/70) vs. 81.6% (71/87), χ2= 30.629, P < 0.001]. Other variables of SOFA were not different between the two groups. ③Based upon the results of all submitted questionnaires, 566 mistakes were identified. It was indicated that the mistakes per capital was 2.9 in the whole cohort and in the two groups. The first type mistakes which caused by carelessness (including calculating error, filling error, choosing error) were 233 times. The calculating error in norepinephrine from NUC physicians was higher than the UC group [33.9% (37/109) vs. 19.3% (17/88), χ2= 5.235, P =0.022], there was no significant difference in any other first type mistakes between the two groups. The total second type mistakes caused by misunderstanding of SOFA (including using wrong variables, not using the worst value within 24 hours, and incorrect GCS score) were 333 times in the whole cohort. GCS error [61.8% (42/88) vs. 16.9% (14/109), χ2=32.292, P<0.001], and using urine output per hour instead of urine output per 24 hours [15.9% (14/88) vs. 4.6% (5/109), χ2= 7.162, P = 0.007] were much higher in UC group than NUC group. Conclusions The total accuracy of SOFA scoring in the investigated emergency physicians of 8 hospitals in Beijing was not good. Mistakes causing by carelessness or misunderstanding of score rules were similar. It is necessary to apply strict training in SOFA scoring.

Objective To investigate the clinicopathological characteristics, patterns of lymph node metastasis and the influencing factors in esophageal adenocarcinoma. Methods A total of 201 cases of esophageal adenocarcinoma were selected for this study, including 89 cases of pure adenocarcinoma, 57 cases of adenoacanthoma cell carcinoma, 33 cases of mucoepidermoid carcinoma and 22 cases of adenoid cystic carcinoma. A total of 2026 lymph nodes were dissected with an average of 10 lymph nodes. The rule of lymph node metastasis in patients with esophageal adenocarcinoma was analyzed, and the risk factors for lymph node metastasis were identified. Results Esophageal adenocarcinoma in the middle thoracic esophagus accounted for 50.7% of all patients, and 43.8% in the lower thoracic esophagus. Ninety out of 201 cases (44.8%) had lymph node metastasis. 322 lymph nodes were positive for metastatic adenocarcioma with a metastatic ratio of 15.9% (322/2026).Among the patients with upper?thoracic esophageal carcinoma, 9.1% (1/11) of the cases had lymph node metastasis in the superior mediastinum but no lymph node metastasis was found in the middle mediastinum, lower mediastinal and abdominal lymph nodes. The middle?thoracic esophageal adenocarcinoma showed more extensive lymph node metastasis. Lower mediastinal and abdominal lymph node metastases were common in lower?thoracic esophageal cancer. Multivariate analysis showed that gender, length of lesion, depth of invasion and vascular invasion were independent risk factors for lymph node metastasis in esophageal adenocarcinoma ( P=0. 010, P=0. 006, P=0. 000, P=0. 019, respectively) . Male patients had more lymph node metastasis than female patients ( 49. 1% vs 26. 3%, P=0.011). The rates of lymph node metastasis in the tumor length ≤3 cm group, 3.1?5 cm group and >5 cm group were 20.4%, 42.9% and 65.7%, respectively. Lymphatic metastasis rates in the T1, T2, T3, T4 stage cancers were 7.1%, 36.8%, 38.1% and 69.4%, respectively, (P<0.001). Patients with vascular invasion had a higher rate of lymph node metastasis ( 73. 9%) than the patients without vascular invasion (41.0%) (P=0.003). Conclusions Most of the esophageal adenocarcinoma are distributed in the middle thoracic esophagus, followed by that in the lower thoracic segment. The lymph node metastasis rate, lymph node metastasis ratio and pattern of lymph node metastasis are similar to those of esophageal squamous cell carcinoma. Male, tumor length, depth of invasion and vascular invasion are risk factors of lymph node metastasis for patients with esophageal adenocarcinoma.
