OBJECTIVE: To analyze the rules of moxibustion for low back pain by ZHOU Meisheng by using data mining and knowledge graph technology. METHODS: Taking the medical cases of moxibustion for low back pain from ZHOU Meisheng's legacy manuscripts and existing works as the research objects, information on disease types, symptoms, tongue manifestations, pulse conditions, syndrome patterns, moxibustion methods and acupoints were collected. Frequency statistics and community analysis were conducted by the ancient and modern medical record cloud platform V 2.3.7, cluster analysis of high-frequency acupoints was performed by SPSS26.0, association rule analysis of high-frequency acupoints was performed by SPSS Modeler 18.0, and the generated linked data were imported into Cytoscape 3.9.1 for complex network analysis. Knowledge graph of moxibustion for low back pain by ZHOU Meisheng was constructed based on the results of data mining. The data storage and display of knowledge graph were realized through the Neo4j 3.5.25 graph database, and the Cypher query language was used for knowledge graph retrieval and discovery. RESULTS: A total of 219 medical cases were collected, involving 14 disease types, 85 related clinical symptoms, 5 related TCM syndrome types, and 6 moxibustion methods. The acupoints were mostly attributed to the governor vessel, the bladder meridian of foot-taiyang, non-meridian and non-acupoint areas. The core prescription of acupoints derived from complex network analysis included tender points, Shenshu (BL23), Jinsuo (GV8), Yinjiao (CV7), Yaoyangguan (GV3), Yanglingquan (GB34), which were largely coincides with high-frequency acupoints. Cluster analysis obtained 4 cluster combinations. Community analysis yielded 6 communities, each corresponding to different acupoints.The constructed knowledge graph contained 187 nodes and 696 relationships, by retrieving clinical elements related to low back pain, the disease-moxibustion association graph, disease-acupoint association graph, accompanying symptom-acupoint association graph and syndrome type-matching point association graph were obtained. CONCLUSION When treating low back pain with moxibustion, ZHOU Meisheng adopts the principle of promoting circulation, distinguishing diseases to determine the treatment, selecting acupoints according to the diseases, and matching points according to the symptoms.And taking tender points, Shenshu (BL23), Jinsuo (GV8), Yinjiao (CV7), Yaoyangguan (GV3), Yanglingquan (GB34) as core acupoints, combined with tenderness point selection, acupoint selection based on meridian and zangfu syndrome differentiation, "sunshine area" acupoint selection, yin-yang acupoint matching. Additionally, he skillfully employs special points, such as Zhongzhu (KI15) and ear tips, pays attention to the reform of moxibustion tools, and innovates the moxibustion techniques, using distinctive moxibustion tools and methods to treat low back pain.

Objective:To analyze the epidemiological characteristics of mumps in China under the immunization strategies of different doses of mumps-containing vaccines(MuCV) by analyzing the national mumps surveillance data from 2020 to 2023.Methods:Based on the national mumps surveillance data from 2020 to 2023, a comparative analysis was conducted on the mumps incidence and the distribution characteristics of mumps cases in time, region and population in the three different periods of 2004-2007 (without MuCV implementation), 2008-2019 (one-dose MuCV implementation) and 2020-2023 (two-dose MuCV implementation) in China.Results:From 2020 to 2023, the annual incidence rate of mumps was 6.48-9.20/100 000, and the annual number of reported cases was 91 303-129 120 cases. After the implementation of the 2-dose MuCV immunization strategy, the epidemiological characteristics of mumps in China have changed to some extent. Compared with the period of 2004-2007 and 2008-2019, the traditional seasonal epidemic pattern of mumps disappeared from 2020 to 2023, with no obvious epidemic peak throughout the year. There was no significant regional difference in the incidence of mumps. Children and adolescents under 15 years of age were the main population of mumps (accounting for 85.46%), of which children aged 5-9 years accounted for 45.07%. Compared with the period of 2004-2007 and 2008-2019, the proportion of mumps cases in the 0-4 years old group showed an increasing trend, the proportion of mumps cases in the 10-14 years old group showed a decreasing trend, and the proportion of adult cases over 40 years old also increased from 2020 to 2023. The age group with the highest incidence of mumps was found to have shifted from 7 years old to 4 years old.Conclusions:The 2-dose MuCV immunization strategy has effectively reduced the incidence of mumps in China. It is necessary to strengthen the surveillance of mumps in kindergartens and primary school children.

As essential concepts of the traditional Chinese medicine theory,"deficiency"and"toxin"have been enriched and developed continuously since Huangdi Neijing.By tracing back and combing"deficiency"and"toxin",this paper sums up their relationship,analyzes and explains their basic connotation,and discusses their extension.The"deficiency-toxin"theory has two meanings:it covers the pathological state of the human body with deficiency of vital qi and excess of pathogenic toxin,and it also refers to the pathological evolutionary process in which"deficiency"and"toxin"promote each other.Based on the connotation and dynamic pathogenesis of the"deficiency-toxin"theory,it is pointed out that this theory can be applied to the prevention and treatment of infectious diseases and chronic debilitating diseases,including the"inflammation-cancer transformation"of inflammatory bowel disease.Taking inflammatory bowel disease as an example and combining its Western medical background,this paper expounds on the pathogenesis and treatment of the"inflammation-cancer transformation"of inflammatory bowel disease,and provides a paradigm of"deficiency-toxin"theory guiding clinical research.

Objective:To compare clinical features of patients with pyogenic liver abscesses with and without septated lobulations.Methods:Patients diagnosed to have pyogenic liver abscesses who were treated in our hospital from January 2011 to March 2021 were enrolled into this retrospective study. There were 203 males and 132 females, with age of (56±14) years old. The patients were divided into two groups by findings on computed tomography and ultrasound into the septated lobulation group ( n=68) and the non-septated lobulation group ( n=267). The clinical data of these patients were compared. Results:In the septated lobulation group, the neutrophil count was 9.17(5.97, 12.33)×10 9/L and the TBil was 17.65(11.92, 27.84) μmol/L. These were significantly higher than the corresponding figures of 7.81(5.42, 10.81)×10 9/L, 12.90(9.00, 19.68) μmol/L, respectively in the non-septated lobulation group ( P<0.05). The difference in the maximum diameters of the septated lobulation group was also significantly larger than the non-septated lobulation group ( P=0.032). Additionally, pus culture showed the proportion of Klebsiella pneumoniae positive patients in the septated lobulation group was significantly higher than that in the non-septated lobulation group [41.18% (28/68) vs. 25.84% (69/267), P=0.013]. The use of fluoroquinolones in patients in the septated lobulation group was higher than that in the non-septated lobulation group [20.59% (14/68) vs. 10.11% (27/267), &chi; 2=5.54, P=0.019]. Conclusion:Compared to patients without septated lobulations, those with septated lobulations had a larger diameter of abscesses, a higher positive rate of Klebsiella pneumoniae on pus culture and a higher proportion of patients receiving fluoroquinolones.

Objective:To investigate the efficacy and safety of cedilanid in the treatment of severe pneumonia in infants and the value of preventing heart failure.Methods:A total of 80 children with severe pneumonia admitted to Dezhou Maternal and Child Health Hospital from January 2019 to December 2020 were selected and randomly divided into the control group and the observation group, with 40 cases in each group. The control group received comprehensive treatment, while the observation group was treated with cedilanid (0.01 mg/kg, one-time intravenous injection) on the basis of the control group. The efficacy of both groups was observed after 5 d of treatment. The incidence of heart failure, correction time of heart failure, improvement time of symptoms and signs, and length of hospitalization time were compared between the two groups; the inflammatory markers, myocardial markers and arterial blood gas indexes were compared between the two groups before and after the treatment.Results:The total effective rate in the observation group was higher than that in the control group, and the incidence of heart failure in the observation group was lower than that in the control group: 90.0% (36/40) vs. 72.5% (29/40), 32.5%(13/40) vs. 10.0%(4/40), the differences were statistically significant ( &chi;2 = 4.02, 4.10, P<0.05). The improvement time of symptoms and signs (restlessness elimination, respiratory improvement, heart rate improvement and disappearance of rhonchus in lung) in the observation group were less than those in the control group ( P<0.05). The levels of procalcitonin (PCT) and N-terminal pro-brain natriuretic peptide (NT-ProBNP), myocardial troponin I(cTnI), and creatine kinase isoenzyme (CK-MB) in the observation group after treatment were lower than those in the control group: (6.15 ± 1.03) μg/L vs. (10.85 ± 2.12) μg/L, (112.02 ± 30.09) ng/L vs. (215.39 ± 55.08) ng/L, (0.68 ± 0.17) μg/L vs. (1.12 ± 0.34) μg/L, (19.05 ± 6.11) U/L vs. (28.97 ± 7.82) U/L, P<0.05. The levels of oxygen partial pressure (PaO 2), blood oxygen saturation (SaO 2) and oxygenation index (PaO 2/FiO 2) in the observation group after treatment were higher than those in the control group: (6.15 ± 1.03) μg/L vs. (10.85 ± 2.12) μg/L, (112.02 ± 30.09) ng/L vs. (215.39 ± 55.08) ng/L, (0.68 ± 0.17) μg/L vs. (1.12 ± 0.34) μg/L, (19.05 ± 6.11) U/L vs. (28.97 ± 7.82) U/L, P<0.05. Conclusions:Early application of small dose of cedilanid in infants with severe pneumonia can effectively reduce the occurrence of heart failure, improve the clinical symptoms and blood gas indicators, with significant curative effect, which is worthy of promotion.

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and is the fourth-leading cause of cancer-related deaths worldwide. HCC is refractory to many standard cancer treatments and the prognosis is often poor, highlighting a pressing need to identify biomarkers of aggressiveness and potential targets for future treatments. Kinesin family member 2C (KIF2C) is reported to be highly expressed in several human tumors. Nevertheless, the molecular mechanisms underlying the role of KIF2C in tumor development and progression have not been investigated. In this study, we found that KIF2C expression was significantly upregulated in HCC, and that KIF2C up-regulation was associated with a poor prognosis. Utilizing both gain and loss of function assays, we showed that KIF2C promoted HCC cell proliferation, migration, invasion, and metastasis both in vitro and in vivo. Mechanistically, we identified TBC1D7 as a binding partner of KIF2C, and this interaction disrupts the formation of the TSC complex, resulting in the enhancement of mammalian target of rapamycin complex1 (mTORC1) signal transduction. Additionally, we found that KIF2C is a direct target of the Wnt/β-catenin pathway, and acts as a key factor in mediating the crosstalk between Wnt/β-catenin and mTORC1 signaling. Thus, the results of our study establish a link between Wnt/β-catenin and mTORC1 signaling, which highlights the potential of KIF2C as a therapeutic target for the treatment of HCC.

Objective: To identify the function of 91-112 amino acids (aa) fragment, the interaction domain of head and stalk of Newcastle disease virus(NDV) HN glycoprotein, and clarify the role of the fragment in promoting cell specific membrane fusion. Methods: The specific gene sequences were identified by aligning 91-112 amino acids of NDV HN protein with amino acids of MeV H, RSV G, hPIV3 HN protein. The fragment deletion, fragment substitution and intermolecular homologous recombination method were combined to construct the deletion mutant, De(HN), and three chimeras, Ch(MeV), Ch(RSV), Ch(hPIV3). Cationic transfection reagent was used to transfect the plasmids into baby hamster kidney cells (BHK-21), in which vaccinia virus-T7 RNA polymerase expression system was expressed. Indirect immunofluorescence assay (IIFA) and flow cytometry (FCM) were executed to analyze the cell surface expression level. Cell fusion promotion activity, receptor recognition activity and neuraminidase activity of each mutant were also detected. Results: Cell surface expression efficiency of De(HN) and Ch(MeV), Ch(RSV), Ch(hPIV3) proteins were 9.04%, 82.20%, 70.16%, 75.65% of that of wild-type (wt) HN. Fusion promotion activity of De(HN), Ch(MeV), Ch(RSV), Ch(hPIV3) were 3.83%, 24.76%, 29.42%, 57.84% of that of wt HN. The fusion promotion activity of De(HN) almost disappeared and syncytium couldn’t be found under the microscope. Hemadsorption activity was 13.48%, 36.25%, 34.93%, 65.22%, respectively (P<0.05), which was consistent with the fusion promotion activity of mutant proteins. Neuraminidase activity was 10.81%, 54.42%, 50.13%, 60.35% of that of wt HN, respectively (P<0.05). Conclusions The amino acids fragment (91-112) of NDV HN protein plays an important role in promotion fusion. The loss of fusion promotion activity of De(HN) protein was related to the failure of effective cell surface expression of the mutant.

The family Paramyxoviridae is a group of viruses that significantly affect human and animal health. Paramyxoviruses are generally thought to enter host cells by direct fusion of the viral and host cell membranes. Membrane fusion, essential for syncytium formation, is not only a pathological hallmark of paramyxoviral infections, but also a kind of mechanism of cell-to-cell viral spread. Nevertheless, the process of membrane fusion is highly conserved, only consisting of two-component fusion apparatus: an attachment protein (HN/G/H) and a fusion (F) protein. However, there is a significant knowledge gap on the mechanism(s) by which HN/H/G couples receptor binding to F-triggering, since different attachment proteins possess special triggering process. In this review, we summarize the general property and distinction of the fusion process during paramyxoviral infection for further research on the pathogenic mechanism.
