This paper systematically reviewed the concept of authentication studies on traditional Chinese medicine （TCM） classics and the research achievements of scholars across historical and contemporary periods. We categorized the authentication studies on TCM classics into four types， including work-oriented authentication research， metho-dological studies on authentication， extended authentication research， and single-book authentication. Multiple methods were applied comprehensively， including investigating bibliographic documents of successive dynasties， analyzing the academic contents of medical books， studying the textual characteristics of medical books， examining the cited references in medical books， verifying the biographies of authors， and analyzing the interpolations and accretions in medical books， to distinguish the authenticity of TCM classics. The academic value of authenticity identification of TCM classics is concluded in three aspects，i.e. it serves as an important means to distinguish authenticity from falsehood in TCM classics， an important guarantee for inheriting the essence of TCM literature， and a key to unlocking the academic treasure trove of TCM classics and achieving inheritance-based innovation， which will lay a solid documentary foundation for constructing identification methodologies and standardized systems.

By sorting out the records of Atractylodis Macrocephalae Rhizoma as food and medicine, this article believed that Atractylodis Macrocephalae Rhizoma as the same origin of medicine and food for a long history, the earliest in the Qin and Han Dynasty Shen Nong Ben Cao Jing: "Zhu, bitter and warm, having efficacy for cold, dampness, paralysis of dead muscles, and spasm; antiperspirant, removing heat, digesting food, and be used as decoction bait; taking for a long time, losing weight and prolonging life, and don't be hungry". On the basis of Shen Nong Ben Cao Jing, later doctors continue to conduct long-term clinical observation and compatibility of its medicine and food efficacy, which is widely used in internal, external, gynaecology, pediatrics, skin and other departments, to treat spleen and stomach diseases, epidemic diseases, kidney diseases, etc. At the same time of clinical practice, Atractylodis Macrocephalae Rhizoma is also widely used in the folk for dietary therapy, including decoction bait, ointment, decoction, soup and other edible methods. Therefore, as a medicine and food and health preservation product, Atractylodis Macrocephalae Rhizoma has great development potential in daily health care and disease diagnosis and treatment with the effects of non-toxic, satiety and longevity.

With reference to the Information and Documentation-Resource Description (GB/T 3792-2021) and Bibliographical Description for Ancient Chinese Books (GB/T 3792.7-2008) and other cataloging standards and rules, drawing on the practical experience of cataloging ancient TCM books, Bibliographical Cataloging for Ancient TCM Books was formulated. This standard specifies the entry items and their order of ancient TCM books, cataloging identifier, cataloging text, cataloging information source, and cataloging item details. The standard can provide standardized and unified guiding principles and methods for the work of ancient TCM books, and promote the sharing and utilization of ancient TCM books.

Objective:To evaluate the efficacy and safety of acupuncture combined with antihypertensive drugs in the treatment of essential hypertension through meta-analysis.Methods:RCTs about acupuncture combined with antihypertensive drugs in the treatment of essential hypertension were retrieved from CNKI, VIP, WANFANG, CBM, PubMed, Embase and Web of Science from the establishment of the databases to January 28, 2022. The risk and quality of literature publication bias were evaluated according to Cochrane 5.1.0 System Evaluation Manual, and relevant data were extracted. RevMan 5.4 software was used for meta-analysis.Results:A total of 36 RCTs involving 2 905 patients were included. Meta-analysis results showed that compared with antihypertensive drugs, acupuncture alone demonstrated advantages in reducing systolic blood pressure [ SMD=-0.70 (-1.05, -0.36), P<0.01], diastolic blood pressure [ SMD=-0.69(-1.06, -0.32), P<0.01], antihypertensive efficacy [ RR=1.11 (1.04, 1.19), P<0.01], symptomes efficacy [ RR=1.21 (1.11, 1.31), P<0.01] and comprehensive efficacy [ RR=1.35 (1.16, 1.57), P<0.01], without serious adverse reactions. Conclusion:Acupuncture alone has good clinical efficacy and safety in the treatment of essential hypertension, compared with antihypertensive drugs alone. However, researches with large samples and high quality are still needed to support the conclusion.

The surveys of the number of TCM ancient books, the bibliography classification methods, the bibliography publication, the bibliography network sharing and access, the evaluation of the classification method of subject bibliography on TCM ancient books and the relevant opinions and suggestions were sent to 30 TCM libraries and 24 comprehensive libraries in China. The questionnaires’ data and responses were analyzed, in order to understand the classification methods of TCM ancient books, the use situation, and the needs in the classification and cataloging work. The results showed that compared with the comprehensive libraries, the collection of TCM ancient books were concentrated in TCM libraries, the classification methods for TCM libraries were seldomly reported, and the classification methods were mainly self-compiled. Thus, the uniformity of the classification methods was poor, and there was also a significant gap in the standardization of the bibliography arrangement in TCM libraries. The result recommended that the domestic library industry urgently needed a unified and standardized classification for TCM ancient books. It was significant for promoting the sharing and exchange of TCM ancient books, promoting the standardization process of TCM information, and promoting the efficient implementation of Zhonghua Yizang compilation project.

BACKGROUND:The ligamentum flavum is important to connect the rear of the spine. If the flexibility of the ligamentum flavum is decreased due to degeneration, in the role of various factors, it can reduce the effective space of the spinal canal to induce spinal cord and nerve root compression, thereby resulting in neurological symptoms, even paralysis or residual disease. OBJECTIVE:To study the mechanism of over-dose fluoride on the degeneration and ossification of the ligamentum flavum in rats. METHODS:Thirty male Sprague-Dawley rats were randomly divided into two groups: experimental group was given distiled water containing NaF (mass fraction 10-4) and control group was given the same amount of distiled water. After 3 and 6 months, the bone mineral density, Ca2+ and P3+ contents in serum and bone tissue and serum alkaline phosphatase activity were detected, respectively. Meanwhile, the ligamentum flavum specimens were taken for X-ray examination and histopathological observation. RESULTS AND CONCLUSION: In the experimental group, chalk stripes or spots occurred in the lower incisors of five rats at 3 months after treatment and dental fluorosis that was mostly in chalk color was found in al the rats at 6 months after treatment; moreover, the bone density of the lumbar spine significantly increased (P < 0.05). Compared with the control group, the contents of serum Ca2+ were significantly higher, while the contents of P3+were significantly lower in the experimental group at 3 and 6 months after treatment (P < 0.05); the serum alkaline phosphatase activity was also significantly higher in the experimental group than the control group at 3 and 6 months after treatment (P < 0.05). X-ray films, at 6 months after treatment, showed that the bone density of the lumbar vertebra was increased obviously; pathological observation showed that the number of elastic fibers in the ligamentum flavum was reduced further, a large amount of colagen fibers, fibroblasts and calcium deposition were found, and the ossification of the ligamentum flavum was visible at the lamina attachment site. These findings indicate that the over-dose fluorides can lead to the degeneration and ossification of the ligamentum flavum in Sprague-Dawley rats, which may plan an important role in the ossification of the ligamentum flavum.

Aim To determine the neuroprotective effect of sulfated pachymaran (SP)on MPTP-induced
mouse model.Method ICR mice were randomly di-vided into control group,MPTP group and SP treatment group (50,1 00,1 50 mg·kg -1 ,ip).After 1 7 days, the activities of endogenous antioxidants (SOD,GSH-Px,CAT),antisuperoxide anion,hydrogen peroxide and MDA content in the midbrain and cortex were as-sayed.Results The results proved that SP significant-ly reduced the content of MDA and H2 O2 ,regulated
the activities of antioxidant enzyme and increased the activity of antisuperoxide anion.Conclusion All these effects indicate that SP is a potential neuroprotective a-gent and its neuroprotective effects are achieved in the MPTP mouse model.

This article was aimed to study the semantic relationship of clinical terminology of traditional Chinese medicine (TCM) from 3 000 clinical medical records and outpatient medical records from books. The aim was to verify the coverage of semantic relationships of UMLS and SNOMED in medical language system with real medical records. The extraction was from the practical aspect in order to improve the semantic relationships involved in TCM clinical practice processes.

Objective To explore the clinical value of interleukin-6 (IL-6)and interleukin-8 (IL-8)in monitoring chorioamnionitis of pregnant women with premature rupture of membrane (PROM).Methods Forty-five pregnant women with PROM delivered in our hospital were select-ed as research group,and 30 normal pregnant women in our hospital were collected as control group at the same term.The levels of serum IL-6 and IL-8 in both groups were detected with enzyme-linked immunosorbent assay (ELISA),and the fetal membrane tissues were taken to conduct patho-logical examination after delivery.Results The levels of serum IL-6 and IL-8 in research group were significantly higher than in control group,with statistical significance.According to the patho-logical examination on fetal membrane tissues,28 patients (62.2%)were diagnosed as chorioam-nionitis (infection group),and 17 ones (37.8%)were not (non-infection group).The levels of serum IL-6 and IL-8 in infection group were significantly higher than in non-infection group,in which significant differences were presented.Conclusion Joint detection of IL-6 and IL-8 in serum of pregnant women can be used as the important index for monitoring PROM combined with chorioamnionitis.
