Polygonatum sibiricum， as a traditional Chinese medicine with both medicinal and edible properties， has attracted considerable attention due to its functions of nourishing Yin and moistening the lungs， tonifying the spleen and benefiting Qi， and nourishing the kidneys and filling essence. Recent studies have demonstrated that Polygonatum sibiricum plays a significant role in regulating the immune system， effectively enhancing and improving the morphology and function of immune organs， stimulating the proliferation and activation of immune cells， and regulating the secretion and release of immune factors， thereby enhancing the immune function of the body and improving various immune-related diseases. Although a large number of studies have explored the pharmacological effects and mechanisms of P. sibiricum， there has been no systematic review and summary of its immune regulatory activity and mechanisms. Therefore， this article comprehensively reviews the research achievements of P. sibiricum polysaccharides and saponins in the field of immune regulation in recent years， and further sorts out the immune regulatory mechanisms of P. sibiricum in multiple aspects： including increasing the organ index of the spleen and thymus， increasing the number and activity of tumor-suppressive bone marrow hematopoietic stem cells， improving intestinal flora imbalance， regulating the quantity and proportion of T lymphocyte subsets， increasing the level of immunoglobulin， promoting the proliferation of macrophages， enhancing the activity of natural killer cells， increasing the number of white blood cells， and promoting the maturation of dendritic cells， providing a solid theoretical basis and scientific evidence for the research and application of P. sibiricum， and promoting its development and application in traditional Chinese medicine immune enhancers and various functional products.

Objective:To analyze and compare the health education efforts of respiratory infectious diseases at home and abroad.Methods:The literature related to health education and popular science of respiratory infectious diseases included in the databases of China National Knowledge Infrastructure (CNKI) and Web of Science (WOS) from January 1, 2003 to December 31, 2023 was searched. A total of 4 686 articles were retrieved in CNKI, 1 540 articles unrelated to the theme were excluded, and 3 146 Chinese articles were obtained. In the WOS database, 7 724 articles were retrieved, 3 685 articles about the clinical mechanism of diseases, pharmacology, and other research topics were excluded, and 4 039 English articles were obtained. The information of annual publications, institutions, authors and keywords was analyzed by using CiteSpace visualization software, and the publication status, research hotspots and development trends of health education related to respiratory infectious diseases at home and abroad were analyzed.Results:Since 2003, the number of publications in health education on respiratory infectious diseases at home and abroad had shown a fluctuating growth trend, and in 2020, the field showed a sharp growth trend at home and abroad. There was no core author group in this field in China, and the network density of domestic authors was 0.006 5, and the network density of foreign authors was 0.009 6. The domestic institutions were mainly the Center for Disease Control and Prevention and medical institutions, including Guangzhou Chest Hospital (29 articles) and the Chinese Center for Disease Control and Prevention (10 articles); Foreign research institutions were mainly higher education institutions, including the University of London (91 articles) and Harvard University (67 articles). The network density of domestic was 0.001 3, and the network density of foreign publishing institutions was 0.026 3, the network density was greater than that of Chinese publishing institutions. The emergence of "COVID-19" "Avian influenza" "Knowledge, Attitude, Practice" and "mental health" in China had strong burst (burst intensity: 46.41, 12.12, 10.33, 8.5); "Coronavirus" "coverage" "Avian influenza" and "COVID-19 vaccine" in foreign countries had strong burst (burst intensity: 14.34, 11.06, 10.73, 10.02).Conclusions:At present, the health education of respiratory infectious diseases at home and abroad has received great attention. But the cooperation between domestic authors and research institutions is loose, and the close collaboration needs to be strengthened. There are differences in the research focus of health education on respiratory infectious diseases at home and abroad.

ObjectiveTaking Shengxuebao as the model traditional Chinese medicine（TCM）， this study aims to explore the methodologies and transfer patterns in the composition changes of TCM compound preparations from liquid to solid dosage forms. MethodBased on the previously established ultra-high performance liquid chromatography（UPLC） qualitative and quantitative methods for Shengxuebao， the fingerprint profiles of three preparations of Shengxuebao（homemade decoction， commercially available granules and mixtures） were established， and nineteen components were quantitatively analyzed. The similarities of fingerprint profiles among these three preparations were assessed using the Similarity Evaluation System for Chromatographic Fingerprint of TCM（2012 edition） and the total quantum statistical moment similarity method， respectively. The molecular connectivity index （MCI） and the average molar MCI of the chemical components in the three preparations were calculated. Seventy-two MCI values across 0-8 orders， including 8 subclasses， were calculated. The average molar MCI of 0-3 orders was used to study the "imprint template" structural characteristics and transfer patterns of the medicinal component groups. ResultThe similarities of the fingerprint profile of the decoction with those of the control， granules， and mixtures were 0.971， 0.888 and 0.799， respectively， indicating that the chemical composition of the granules and mixtures differed from that of the decoction， and that the 19 components were able to basically respond to the overall situation of the component group of Shengxuebao decoction. The total mass fractions of the detectable major components in Shengxuebao decoction， granules and mixtures was measured to be 5.498 6， 2.282 0， 1.416 6 mg·g^-1， respectively. The average molar MCI of 0-3 orders showed a gradual decrease across the three preparations， with the trend of decoction>granules>mixtures， indicating subtle changes in the overall structural characteristics of the chemical components in the samples of the three preparations. ConclusionAmong the three formulations of Shengxuebao， the traditional decoction contained the highest variety and quantity of components and carried the most substantial amount of component information， with a decreasing order observed in the granules and mixtures. This study further validates that traditional decoction is a reliable and fundamental dosage form， providing a reference for the modernization of TCM dosage forms and the quality consistency evaluation of compound preparations.

BACKGROUND: Mis Seven implant has become more and more popular in oral implant restoration, and the clinical application in dentate-deficient patients remains to be studied. OBJECTIVE: To explore the short-term effects of the Mis Seven implant system on fixed restorations in dentition loss. METHODS: Nineteen patients undergoing fixed dental prostheses with the Mis Seven system due to dentition loss at the Department of Implants of the Stomatological Hospital of Guangzhou Medical University between April 2015 and December 2017 were included. Three patients had missing maxillary and maxillary dentition and unilateral maxillary teeth. Six patients were loss of maxillary dentition, and there were 10 cases of unilateral mandibular dentition missing. The total dental implants were 134. All cases were implanted and fixed for one stage. Clinical examination, alveolar bone and inter-implant image performance and post-load repair effect at 6, 12 and 24 months of follow-up were used as evaluation indicators. RESULTS AND CONCLUSION: (1) In 134 implants, failure was in 2 cases due to surrounding tissue infection. The success rate of before implant restoration was 98.51％, and the success rate after repair was 100％. (2) The stability of dentition of 19 patients was good, showing good occlusion. No mechanical complications or biological complications occurred. The stability of the restoration was 100％. (3) The vertical absorption of bone tissue around all implants was less than 0.2 mm at 6, 12, 24 months after repair, suggesting that the implant has no obvious edge bone resorption. The gingival tissues around all implants were healthy, and no unhealed inflammation or hyperkeratosis appeared. (4) These results imply that the Mis Seven system in the dentition defect fixation exhibits good short-term clinical results.

Objective To investigate the dynamic images of traumatic penumbra(TP)in a rat model of traumatic brain injury (TBI)treated with AQP4-RNAi using multimodal MRI(MM-MRI)at 7.0 Tesla.Methods A rat model of TBI was established by the improved Feeney's method.MRI scans were performed including T2WI,DWI,ADC and SWI.The pathological changes in penumbra area were observed.All statistical analyses were performed using SPSS 21.0 software package.Results Over time rs-T2WI,rs-DWI and rs-SWI in TBI group were gradually increased.The r-ADC began to increase at one hour after trauma and reached the peak at 6 h. Then it began to fall and reached the bottom at 12 h.At each time point,the difference was statistically significant(P<0.05).Compared with RNA interference group,the rs-T2WI and rs-DWI in TBI group were decreased significantly at 6 h and 12 h(P<0.05),the r-ADC was not decreased significantly at 1 h(P>0.05)and decreased significantly at 6 h and 12 h(P<0.05).At each time point,there was no significant difference in rs-SWI(P>0.05).The area of mismatch between rs-SWI and rs-DWI was the most obvious at 6 h and 12 h,and the area of mismatch was decreased in size after treatment with AQP4-RNAi.There was no significant difference between TBI group and placebo group(P>0.05).In two groups,similar pathological changes were observed,which was depicted as vasogenic edema predominantly at 1 h and mixed edema at 6 h and 12 h. In RNA interference group,intracellular edema was markedly reduced at 6 h and 12 h,and the vasogenic edema was relieved to some extent at 12 h.Conclusion The treatment with APQ4-RNAi markedly alleviates cerebral edema.MM-MRI can reflect its pathological changes.The area of mismatch between SWI and DWI can prompt early detection of traumatic penumbra,which may provide useful information for clinical treatment.

Objective To explore the application value of fractional anisotropy(FA)values of magnetic resonance diffusion tensor imaging(DTI)parameters in rat rat glioma grading.Methods Sixty-seven female Wistar rats were divided into the experi-mental group(n=57)and control group(n=10)according to the random number table method.All the surviving rats were exam-ined by 3.0T DTI at 1-2 weeks(22 cases)and 3-4 weeks(35 cases)after inoculation,and the FA values of the tumor were ob-tained and compared with the pathological results.Results Among 57 tumor-loading rats,there were 18 low-grade gliomas and 39 high-grade gliomas.DTI showed that the FA value of high-grade gliomas was higher than that of the low-grade glioma,the differ-ence was statistically significant[(0.167 ± 0.035)vs.(0.147 ± 0.015),t=2.34,P<0.05].Conclusion The FA value of DTI pa-rameters can provide accurate,reliable and noninvasive imaging information for preoperative glioma grading.

Objective: To investigate the value of short tandem repeat (STR) genotyping in the diagnostic workup of molar and non-molar gestations with correlation of histological characteristics. Methods: Six hundred and fifty-six cases were selected based on clinically suspected hydropic abortion and/or molar pregnancy from July 2015 to September 2017 at Beijing Obstetrics and Gynecology Hospital. DNA was extracted from dissected chorionic villi and paired maternal endometrial FFPE tissue samples by Simplex OUP™ FFPE DNA Tissue Kit. STR genotyping was performed by PowerPlex 16 HS system. Results: DNA genotyping was informative in 649 of 656 cases, leading to identification of 215 hydatidiform mole gestations and 434 non-molar gestations. Most of non-molar gestations (375 cases, 86.4%) were diploid hydropic abortion. Various trisomy syndromes were found (53 cases, 12.2%), including trisomy 2, 3, 4, 7, 8, 13, 16 and 21. Only 2(0.5%) digynic triploid gestations were detected. Moreover, 4 cases (0.9%) of uniparental disomies (homologous or heterologous) were found. There were 196 cases with histologic diagnostic suspicious of hydatidiform moles were accurate sub-classified. Among them, 59 cases hydatidiform moles were under-diagnosed as diploid hydropic abortions, and 28 cases diploid hydropic abortions were over-diagnosed as hydatidiform moles.Compared with partial moles(PHM), there were no specific histomorphological features between the various types of non-molar gestations and partial moles for definitive diagnostic separation. There was no significant difference in the expression of p57^kip2 among PHM, trisomy and diploid hydropic abortions group (P=0.247). Conclusions STR genotyping can distinguish non-molar gestations from early hydatidiform moles, and efficiently avoid misdiagnosis based only on histological evaluation. Therefore, using STR genotyping, not only can the overdiagnosis of non-molar pregnancy be avoided, but also individualized management can be offered to patients including monitoring of serum hCG.

Objective To investigate the demand of patients with coronary heart disease (CHD) for transitional care service in a tertiary hospital of Shaanxi,in order to provide more reasonable and effective transitional care service measures for patients.Methods A total of 721 patients with CHD (two days before their discharge) in a tertiary hospital of Shaanxi were selected from May to October 2015,and were investigated by using self-designed transitional care questionnaire.Results There were 50.3% of patients with CHD willing to accept the transitional care service and only 0.8% of them not willing to receive the transitional care service. There were 51.2% of the patients willing to accept the telephone follow-up from the ward,and 60.5% of them willing to get other transitional care services,including the guidance of self-monitoring vital signs, guidance of diet and moderate exercise,guidance of disease recurrence prevention,attentions of life work after discharge,and first-aid knowledge. There were 88.8% of the patients using the mobile phone as the main communication tools. There were 34.4% of patients who need the telephone follow-up from the ward and 35% of them willing to receive text message alerts for one month. There were 53.7% of the patients who can accept the cost of transitional care service less than 10 yuan per time,and 50.3% of them who can accept the cost less than 30 yuan per hour.Conclusions The patients with CHD have great demands for the transitional care service. The transitional care should be established and developed according to patients′ demand after discharge,so as to meet discharged patients′ demand for transitional care.
