ObjectiveTo investigate the mechanisms by which the combination of berberine （BBR） and baicalin （BAI） ameliorates type 2 diabetes mellitus （T2DM） due to internal accumulation of dampness-heat from the perspectives of gut microbiota and metabolomics. MethodsAntibiotics were used to induce pseudo-sterile mice. Thirty pseudo-sterile mice were randomized into a normal fecal microbiota transplantation group （n=10） and a T2DM （syndrome of internal accumulation of dampness-heat） fecal microbiota transplantation group （n=20）. The mice were then administrated with suspensions of fecal microbiota from healthy volunteers and a patient with T2DM due to internal accumulation of dampness-heat by gavage， respectively. Each mouse received 200 µL suspension every other day for a total of 15 times to reshape the gut microbiota. The T2DM model mice were then assigned into a model group （n=8） and a BBR-BAI group （n=11）. BBR was administrated at a dose of 200 mg·kg^-1， and BAI was administrated in a ratio of BBR-BAI 10∶1 based on preliminary research findings. The administration lasted for 8 consecutive weeks. Fasting blood glucose （FBG）， glycated hemoglobin （HbA1c）， insulin （INS）， triglycerides （TG）， total cholesterol （CHOL）， low-density lipoprotein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， aspartate aminotransferase （AST）， and alanine aminotransferase （ALT） levels were measured to evaluate the effects of the BBR-BAI combination on glucose and lipid metabolism and liver function in T2DM mice. Hematoxylin-eosin staining was employed to observe pathological changes in the colon tissue. The expression of claudin-1， zonula occludens-1 （ZO-1）， and occludin in the colon tissue was determined by Western blot. Real-time quantitative polymerase chain reaction（Real-time PCR） was employed to assess the levels of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and interleukin-6 （IL-6） in the colon tissue. The fecal microbiota composition and differential metabolites were analyzed by 16S rRNA sequencing and ultra-high performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry （UPLC-Q-TOF-MS）， respectively. ResultsThe BBR-BAI combination lowered the FBG， HbA1c， and INS levels （P<0.05， P<0.01） and alleviated insulin resistance （P<0.01） in T2DM mice. Additionally， BBR-BAI elevated the levels of ZO-1， occludin， and claudin-1 （P<0.05， P<0.01） and down-regulated the expression levels of TNF-α， IL-1β， and IL-6 in the colon （P<0.05， P<0.01）. The results of 16S rRNA sequencing showed that BBR-BAI increased the relative abundance of Ligilactobacillus， Phascolarctobacterium， and Akkermansia （P<0.05）， while significantly decreasing the relative abundance of Alistipes， Odoribacter， and Colidextribacter （P<0.05）. UPLC-Q-TOF-MS identified 28 differential metabolites， which were primarily involved in arachidonic acid metabolism and α-linolenic acid metabolism. ConclusionBBR-BAI can ameliorate T2DM due to internal accumulation of dampness-heat by modulating the relative abundance of various bacterial genera in the gut microbiota and the expression of fecal metabolites.

Huangqitang comes from the Taiping Huimin Hejiju Fang of the Song dynasty. It consists of four medicinal materials: Astragalus membranaceus var. mongholicus, Citrμs reticμlata， Cannabis sativa， and Apis cerana. It is a classic prescription for treating constipation in the elderly. This study systematically collated the literature records about Huangqitang in ancient Chinese medicine books and combined it with the current status of modern clinical applications to conduct in-depth analysis and research on the origin，composition， dosage, processing, preparation and administration, drug base, main symptoms， and other key information of the formula, so as to provide a strong reference for the development and clinical application of the classic Huangqitang compound preparation. Through systematic combing and textual research on the previous literature of Huangqitang， it can be seen that the formula of Huangqitang was first recorded in the Taiping Huimin Hejiju Fang， and the medical books of the past dynasties mostly adopted this formula. In terms of drug base， the dried roots of the leguminous plant Astragalus membranaceus var. mongholicus are used， and for tangerine， the dried outer peel of the Rutaceae plant Citrus reticμlata and its cultivated varieties are used. The Moraceae plant Cannabis sativa with the peel removed is selected, and the Apis cerana is selected from the honey brewed by Apis cerana， an insect of the Apidae family. In terms of dosage， although the dosage of some drugs changed during the Ming and Qing dynasties, the dosage records basically followed the original prescriptions from the Song dynasty. In terms of processing, preparation, and usage， although the drug processing， preparation， and usage of Huangqitang in the medical books of the past dynasties have changed slightly， they are basically the same as the original prescription of the Song dynasty. In terms of main symptoms, Huangqitang is designed to treat constipation in the elderly. From the Song dynasty to the Qing dynasty， it was mostly used to treat constipation， secret congestion, asthenia， etc. in the elderly. In modern times， it is clinically used to treat constipation due to Qi deficiency， functional constipation， irritable bowel syndrome， and other diseases in the elderly. No adverse reactions have been found yet. In the subsequent research and development， it is necessary to carry out mass spectrometry analysis of Huangqitang， in-depth exploration of its prescription efficacy and mechanism of action， and other multi-omics scientific research. At the same time， it is important to establish quality control standards to provide a reliable scientific basis for the research and development, clinical treatment， and drug supervision of Huangqitang compound preparations.

Objective:To summarize the clinical characteristics and first aid measures of children with drowning，and to provide scientific basis for the treatment and prevention of drowning in children.Methods:The clinical data of drowning children admitted to the Children's Medical Center of the First Affiliated Hospital of Hunan Normal University（Hunan Provincial People's Hospital）from January 2011 to December 2021 were retrospectively summarized. Baseline characteristics，prehospital emergency care and prognosis of the included children were analyzed.According to the time span, drowning children were divided into two stages, the first stage (2011-2016) and the second stage (2017-2021). According to cerebral performance category assessment scale,drowning children with cardiac arrest were divided into two groups: a group with good neurological prognosis and a group with poor neurological prognosis. The baseline characteristics,pre-hospital emergency care, and prognosis of drowning children during different periods and with different prognosis were analyzed.Results:A total of 53 children were enrolled during the study period，with 24 cases in the first phase（2011-2016）and 29 cases in the second phase（2017-2021）.Boys accounted for 73.6%（39/53）of the cases, the age ranged from 1 month and 24 days to 14 years old，with 1-4 years old being the most common，accounting for 58.5%（31/53）, and the season in which drowning occurred was more common in the summer（39.6%, 21/53）.Six cases (11.3%) had significant neurological sequelae, and the mortality rate was 3.8%（2/53）.There was a decrease in the proportion of drowning with water control in the second stage compared to the first stage（37.5% vs. 13.79%, P=0.046）.Thirty-two（60.4%）children experienced on-site cardiopulmonary resuscitation(CPR) after drowning，with 24 cases in the group with good neurological prognosis and 8 cases in the group with poor neurological prognosis.Children in the poor neurological prognosis group required CPR for a long duration [10.00（1.50, 25.00）min]，had lower body temperature，Glasgow Coma Score，pH and higher blood glucose levels on admission（all P < 0.05）. Conclusion:Drowning is most common in preschool children，common in boys，and drowning prevention measures for young children deserve focused attention. Children found to be in cardiac arrest at the time of drowning have a long duration of drowning and CPR，which predicts a poor neurological prognosis，and timely and effective on-site CPR is the key to reducing the drowning rate.

Objective To explore the mechanism of hydroxyl safflower flavin A(HSYA)in the treatment of sepsis-induced liver injury by using metabolomics and network pharmacology.Methods A total of 50 male C57BL/6 mice were randomly divided into sham-operation group(10 mice),sepsis group(20 mice)and HSYA group(20 mice).Cecal ligation and puncture was conducted to establish the sepsis-induced liver injury mouse model.The mice in HSYA group were subcutaneously injected with HSYA after 2 hours of modeling.The content of serum inflammatory factors and liver function were detected,and the pathological changes of liver tissue were observed with HE staining,UPLC-Q-TOF-MS metabolomics was used to analyze liver tissue,screening for differential metabolites using multivariate statistical methods,network pharmacology was used to predict potential targets for HSYA treatment of sepsis-induced liver injury,and conduct GO and KEGG pathway enrichment analysis on potential targets,Metabo Analyst 5.0 database was used to match differential metabolites and potential targets between the model group and HSYA group,a targets metabolite-metabolism pathway network was constructed.AutoDock Vina software was used to perform molecular docking between HSYA and core genes,and finally RT-qPCR was used to verify the expression of core genes.Results HSYA can reduce the contents of IL-6,IL-1β and TNF-α in serum,restore liver function,and alleviate the morphological alternation in liver induced by sepsis.A total of 26 differential metabolites identified by metabolomics were screened out,including flufenamic acid,cryptolepine,opthalmic acid,fenpropathrin etc.,which were mainly involved in 5 metabolic pathways such as biosynthesis of unsaturated fatty acids and alpha-linolenic acid metabolism.Network pharmacology identified 81 potential targets,2 735 items enriched in GO and 124 signaling pathways enriched in KEGG;a total of 5 differential metabolites were matched for joint analysis,corresponding to 14 targets including IL1B,STAT3,PTGS2,TP53,etc.,involved in the regulation of metabolic disorders in sepsis-induced liver injury by HSYA.Molecular docking results showed that HSYA had good binding activity to IL1B,STAT3,PTGS2 and TP53 targets.RT-qPCR results showed that HSYA could inhibit the expressions of IL1B,STAT3 and PTGS2 in liver tissue.Conclusions HSYA may inhibit the release of inflammatory cytokines,maintain metabolic homeostasis,and alleviate sepsis-induced liver injury through modulating the expressions of IL1B,STAT3,and PTGS2.

Accurate segmentation of oral surgery-related tissues from cone beam computed tomography(CBCT)images can significantly accelerate treatment planning and improve surgical accuracy.In this paper,we propose a fully automated tissue segmentation system for dental implant surgery.Specifically,we propose an image preprocessing method based on data distribution histograms,which can adaptively process CBCT images with different parameters.Based on this,we use the bone segmentation network to obtain the segmentation results of alveolar bone,teeth,and maxillary sinus.We use the tooth and mandibular regions as the ROI regions of tooth segmentation and mandibular nerve tube segmentation to achieve the corresponding tasks.The tooth segmentation results can obtain the order information of the dentition.The corresponding experimental results show that our method can achieve higher segmentation accuracy and efficiency compared to existing methods.Its average Dice scores on the tooth,alveolar bone,maxillary sinus,and mandibular canal segmentation tasks were 96.5%,95.4%,93.6%,and 94.8%,respectively.These results demonstrate that it can accelerate the development of digital dentistry.

Asian ginseng mostly appeared in herbal medical books in the late Qing Dynasty and the early Republic of China.In modern literature,it is believed that this drug is alias of vigorously cultivated ginseng,Talinum paniculatum(Jacq.)Gaertn.,Pananis Japonici Rhizoma,Arctii Fructus and other drugs,and the origin is confused.This article made a textual research on the name,origin,producing areas,processing,property and taste,and efficacy.It is concluded that the Asian ginseng was earlier included in the Ben Cao Gang Mu Shi Yi in the Qing Dynasty,and was named Asian ginseng because it was produced in Japan.The original plant is Panax ginseng C.A.Meyer,which is a kind of Araliaceae plant.It takes Yunzhou,Huijin and Xinzhou of Japan as the true land,and is also cultivated in Northeast China.Asian ginseng medicinal materials are made by processing techniques such as net whiskers,boiling,cooling,and exposure to dryness.They are warm in property,sweet and slightly bitter in taste.They are good at tonifying qi and generating fluid,and can treat all deficiency syndromes of fluid and qi.In the Qing Dynasty,they were often used as Ginseng Radix et Rhizoma.The identification of false was also attached for distinguishing.

ObjectiveBased on the hemodynamic indicators of transcranial Doppler （TCD），this study aimed to analyze the correlations of visual analogue scale（VAS） and Hamilton depression rating scale 24-item（HAMD-24） scores with mean blood velocity （Vm） of the anterior cerebral artery （ACA），the middle cerebral artery （MCA）， and the posterior cerebral artery （PCA），and the correlation between VAS score of headache and HAMD-24 score，and explore the clinical efficacy of Xiaoyaosan combined with paroxetine tablets in the treatment of migraine with liver depression and blood deficiency syndrome and depression. MethodSixty-two outpatients treated in the encephalopathy department， the First Afffiliated Hospital of Anhui University of Chinese Medicine between January 2019 to June 2020 who were in line with the diagnostic criteria were enrolled and divided into a treatment group （32 cases） and a control group （30 cases）. All patients were treated with paroxetine tablets，while those in the treatment group received additional Xiaoyaosan. The changes in relevant indicators in the two groups before and after treatment were observed. The effects of Xiaoyaosan on the TCD indicators （Vm_ACA， Vm_MCA， and Vm_PCA）， scores of migraine and depression ［including VAS score， Headache Impact Test-6 （HIT-6） score，and HAMD-24 score］， and the traditional Chinese medicine （TCM） syndrome score were analyzed. ResultVAS and HAMD-24 scores were positively correlated with Vm_ACA， Vm_MCA， and Vm_PCA （P<0.01）. VAS scores were positively correlated with HAMD-24 scores. Compared with the conditions before treatment， the levels of TCD indicators （Vm_ACA， Vm_MCA， and Vm_PCA） in the two groups decreased after treatment （P<0.01）， and the scores of HIT-6， VAS， and HAMD-24 in the two groups were significantly improved （P<0.01）. Compared with the control group after treatment， the treatment group showed decreased levels of TCD indicators （Vm_ACA， Vm_MCA， and Vm_PCA） （P<0.01） and superior improvement of HIT-6， VAS， and HAMD-24 scores （P<0.01）. The effective rate in the treatment group was 90.6% （29/32）， higher than 63.3% （19/30） in the control group （χ²=5.13，P<0.05）. There was no significant difference in adverse reactions between the two groups. ConclusionTCD indicators can effectively reflect the cerebral blood flow of patients with migraine and depression co-morbidity，and migraine is correlated with the onset and severity of depression. The comprehensive analysis showed that the efficacy of Xiaoyaosan combine paroxetine tablets was better than that of paroxetine tablets alone in the treatment of migraine with liver depression and blood deficiency syndrome and depression. This therapeutic protocol can significantly improve cerebral blood flow and the symptoms and degree of migraine and depression and can provide references for clinical treatment.

Objective:To study the expression and clinical significance of microRNA-574-3p (miR-574-3p) in colon cancer.Methods:A total of 106 colon cancer patients who were admitted to the First Hospital of Qinhuangdao and Shijiazhuang Hospital of Traditional Chinese Medicine from June 2012 to June 2015 were selected as the research objects. Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression level of miR-574-3p in colon cancer tissues and normal adjacent tissues. The relationship between the expression of miR-574-3p and the clinicopathological characteristics and prognosis of patients with colon cancer was analyzed. Immunohistochemical staining was used to detect the relationship between the expression of miR-574-3p and the expression of CyclinA2 or E-cadherin.Results:Compared with normal tissues adjacent to cancer, the expression level of miR-574-3p in 106 cases of colon cancer was significantly lower ( P<0.01). The decreased expression of miR-574-3p was related to tumor diameter, Dukes stage, histological grade and lymph node metastasis (all P<0.05), but not to age and tumor location (all P>0.05). The patients with low expression of miR-574-3p, high Dukes stage and histological grade, and lymph node metastasis had poor survival (all P<0.05). The 5-year overall survival rate of patients with decreased miR-574-3p expression in cancer tissue was significantly lower than that of patients without decreased miR-574-3p expression ( P=0.007 6). Compared with patients with no decreased miR-574-3p expression, patients with decreased miR-574-3p expression had higher CyclinA2 protein integrated optical density (IOD) value and lower E-cadherin protein IOD value in colon cancer tissues (all P<0.05). Conclusions:The decreased expression of miR-574-3p is related to the poor prognosis of colon cancer patients, which may affect tumor recurrence and metastasis by regulating the expression of CyclinA2 and E-cadherin proteins.
