This review tried to find regular acupointselection in the treatment of cervical vertigo through literature search. Bibliometric analysis and data mining were referenced. There were a total of 42 relative articles, which cov-ered 86 acupoints, with thefrequency of 382. The acupointsselection of the highest frequency were GB20-Fengchi, EX-Jingjiaji, DU20-Baihui. It was concluded that study on the regular acupoint selection in the treatment of cervical vertigo providedbasis for rational clinical acupoint combination. It had important meaning in the standardization and research of cervical vertigo.

Objective To explore the expressions and significance of brain natriuretic peptide (BNP),hypersensitive C-reactive protein (hs-CRP),human fibrinogen (Fib),D-Dimer and blood gas analysis in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and pulmonary hypertension (PH).Methods Totally 135 patients with AECOPD were divided into single AECOPD group (n =75) and AECOPD + PH group (n =60).The value of pulmonary systolic pressure (PASP) was measured by echocardiography.Serum BNP,hs-CRP,D-Dimer,Fib levels and arterial blood gas analysis indexes such as p(CO2) and p(O2) were compared between two groups.Results The levels of hs-CRP,BNP,D-Dimer and p(CO2) in AECOPD + PH group were significantly higher than those in AECOPD group (P ＜ 0.05),while p (O2) in AECOPD + PH group was significantly lower than that in AECOPD group.Multiple linear regression analysis showed that the levels of hs-CRP,Fib,BNP,D-Dimer and p (CO2) were positively correlated with pulmonary artery pressure (P ＜ O.05),and p (02) was negatively correlated with PASP (P ＜ 0.05).Conclusion The hs-CRP,Fib,BNP,and D-Dimer participate in the formation of AECOPD complicated with pulmonary hypertension,and systemic inflammation plays an important role in the pathogenesis of AECOPD complicated with pulmonary hypertension.

Rabbit hemorrhagic disease was described in China in 1984 and can cause hemorrhagic necrosis of the liver within two or three days after infection. The etiological agent, rabbit hemorrhagic disease virus (RHDV), belongs to the Lagovirus genus in the Caliciviridae family. Compared to other calicivirus, such as rNV and SMSV, the structure of Lagovirus members is not well characterized. In this report, structures of two types of wild RHDV particles, the intact virion and the core-like particle (CLP), were reconstructed by cryo-electron microscopy at 11 &0A and 17 &0A, respectively. This is the first time the 3D structure of wild caliciviruses CLP has been provided, and the 3D structure of intact RHDV virion is the highest resolution structure in Lagovirus. Comparison of the intact virion and CLP structures clearly indicated that CLP was produced from the intact virion with the protrusion dissociated. In contrast with the crystal structures of recombinant Norovirus and San Miguel sea lion virus, the capsomers of RHDV virion exhibited unique structural features and assembly modes. Both P1 and P2 subdomains have interactions inside the AB capsomer, while only P2 subdomains have interaction inside CC capsomer. The pseudo atomic models of RHDV capsomers were constructed by homology modeling and density map fitting, and the rotation of RHDV VP60 P domain with respect to its S domain, compared with SMSV, was observed. Collectively, our cryo-electron microscopic studies of RHDV provide close insight into the structure of Lagovirus, which is important for functional analysis and better vaccine development in the future.

Objective To collect and sort out the literature on the clinical medication experience of traditional Chinese medicine(TCM)in the treatment of hepatic precancerous lesions,and to summarize the characteristics of the disease and the treatment ideas by analyzing the rules of its formula,in order to provide instructions for the treatment of precancerous lesions of hepatocellular carcinoma with TCM in terms of medication and experience addition and subtraction.Methods CNKI,VIP,WanFang Data,CBM,PubMed,Web of Science,EMBASE,Cochrane databases were systematically searched,the clinical research and personal experience literature of TCM in the treatment of hepatic precancerous lesions from the establishment of the databases to December 2023 was included,and the prescription information that met the inclusion criteria was extracted.Based on"Traditional Chinese Medicine data Miner(TCM Miner)",the medication database was established to analyze the frequency,properties and flavours of the drugs and meridian tropism.The cluster analysis were conducted by SPSS 25.0 statistical software,and the association rules were analyzed by using Apriori algorithm of SPSS Modeler 14.1,and the complex network analysis of high-frequency drugs was conducted by network module of SPSS Modeler.Results 34 researches including 34 formulas,110 drugs with 291 frequencies and 15 drug efficacy were included.Frequency analysis showed that the top eight types of frequently applied drugs were milkvetch root,largehead atractylodes rhizome,radix salviae miltiorrhhizae,hedyotis,carapax trionycis,zedorgy rhidoray,barbated skullcup herb,redix curcumae.The top three properties in the"four qi"were cold,warm and mild.The top three tastes of the"five flavors"were bitterness,sweetness and acridity.The top four in the frequency of meridian tropism were liver,spleen,kidney and lung.Apriori correlation analysis showed that the core drug pairs was"Hedyotis diffusa+Atractylodes".Complex network analysis showed that the core prescriptions were composed of Atractylodes,Radix Paeoniae Alba,Hedyotis diffusa,Poria cocos,Rhizoma Curcumae,Radix Curcumae Aromaticae,Trionycis Carapax,Radix Astragali,Sparganium stoloniferum,Salvia miltiorrhiza,Scutellaria barbata.Conclusion The TCM treatment of hepatic precancerous lesions should be based on tonifying spleen and nourishing liver,promoting blood circulation and detoxification,and combined with drugs that can promote qi-circulation,clear heat,remove blood-stasis,soften hard masses and resolve hard masses.

Chinese herbal piece is an important component of the traditional Chinese medicine （TCM） system， and identifying their quality and grading can promote the development and utilization of Chinese herbal pieces. Utilizing deep learning for intelligent identification of Chinese herbal pieces can save time， effort， and cost， while also reasonably avoiding the constraints of human subjectivity， providing a guarantee for efficient identification of Chinese herbal pieces. In this study， a dataset containing 108 kinds of Chinese herbal pieces （14 058 images） was constructed，the basic YOLOv4 algorithm was employed to identify the 108 kinds of Chinese herbal pieces of our database The mean average precision （mAP） of the developed basic YOLOv4 model reached 85.3%. In addition， the receptive field block was introduced into the neck network of YOLOv4 algorithm， and the improved YOLOv4 algorithm was used to identify Chinese herbal pieces. The mAPof the improved YOLOv4 model achieved 88.7%， the average precision of 80 kinds of decoction pieces exceeded 80%， the average precision of 48 kinds of decoction pieces exceeded 90%. These results indicate that adding the receptive field module can help to some extent in the identification of Chinese herbal medicine pieces with different sizes and small volumes. Finally， the average precision of each kind of Chinese herbal medicine piece by the improved YOLOv4 model was further analyzed. Through in-depth analysis of the original images of Chinese herbal medicine pieces with low prediction average precision， it was clarified that the quantity and quality of original images of Chinese herbal medicine pieces are key to performing intelligent object detection. The improved YOLOv4 model constructed in this study can be used for the rapid identification of Chinese herbal pieces， and also provide reference guidance for the manual authentication of Chinese herbal medicine decoction pieces.
