This article systematically analyzes the historical evolution of the name， medicinal parts， origin， harvesting， processing and other aspects of Houttuyniae Herba（HH） by referring to the medical books， prescription books and other documents of the past dynasties， combined with the research materials related to modern and contemporary times， in order to provide a basis for the development of famous classical formulas containing this herb. In ancient literature， HH was often referred to as "Ji" and "Jicai"， the name of "Ji" was first recorded in Mingyi Bielu during the Han and Wei dynasties， and the name of Yuxingcao was first seen in Lyuchanyan Bencao during the southern Song dynasty and has continued to this day. The origin of HH used throughout history is consistent， all of which are the whole herb or aboveground parts of Houttuynia cordata in Saururaceae family. HH recorded throughout history has a wide range of production areas， mostly self-produced self-marketing. In ancient times， fresh HH was often used as medicine by pounding its juice without involving any processing steps. Both fresh and dried products can be used as medicine， the fresh products uses the whole plant， while the dried products uses the aboveground parts， which are cleaned， selected and processed before use. Fresh products are harvested regardless of season， while dried products are harvested in both summer and autumn， with summer as the best. In ancient times， there were no specific requirements for the quality of HH， while in modern times， "intact stems and leaves with a strong fishy smell" are preferred. In addition， the medicinal properties of HH have undergone significant changes from ancient to modern times. In the early period， it was believed that its medicinal property was slightly warm， until the 1977 edition of Chinese Pharmacopoeia officially changed it to slightly cold. Both ancient and modern literature states that HH can be used for the treatment of carbuncle and malignant sores， Lyuchanyan Bencao for the first time introduced HH fresh juice can relieve summer heat， since Diannan Bencao recorded that it can be used for lung carbuncle， and gradually developed into the first choice for the treatment of lung carbuncle. Based on the research results， it is suggested that fresh herb or dried aboveground parts of H. cordata are used as medicine when developing famous classical formulas.

ObjectiveTo analyze the factors influencing meropenem-related liver injury （MRLI） and to explore their clinical predictive value. MethodsA retrospective case-control study was conducted， and the Chinese Hospital Pharmacovigilance System （CHPS） was used to establish a retrieval scheme. A total of 1 625 hospitalized cases using meropenem from January 2018 to December 2022 were collected. Patients were divided into case group （n=62） and control group （n=1 563） based on the presence or absence of liver injury. Clinical data and laboratory indicators from both groups were collected and analyzed. The t-test was used for comparison of normally distributed continuous data between the two groups， while the Mann-Whitney U test was used for comparison of continuous data not conforming to a normal distribution. The chi-square test was used for comparison of categorical data between the two groups. A multivariate Logistic regression analysis was performed to identify the influencing factors for MRLI. A Logistic regression equation was established， and the predictive value of these factors was assessed using the receiver operating characteristic （ROC） curve. ResultsThe results of univariate analysis indicated that the rates of male patients， hypoproteinemia， shock， intensive care unit （ICU） admissions， sepsis， and liver， gallbladder， and cardiovascular diseases， the levels of alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， gamma-glutamyl transpeptidase （GGT）， aspartate aminotransferase （AST）， creatinine （CREA）， and procalcitonin （PCT）， and the number of hospitalization days were significantly higher in the case group than in the control group （P<0.05）， and that the platelet levels in the case group were significantly lower than those in the control group （P<0.05）. The multivariate Logistic regression analysis showed that male sex （odds ratio ［OR］=2.080， 95% confidence interval ［CI］： 1.050 — 4.123， P=0.036）， admission to the ICU （OR=8.207， 95%CI： 4.094‍ ‍—‍ ‍16.453， P<0.001）， comorbidity with gallbladder disease （OR=8.240， 95%CI： 3.605‍ ‍—‍ ‍18.832， P<0.001）， ALP （OR=1.012， 95%CI： 1.004‍ ‍—‍ ‍1.019， P=0.004）， GGT （OR=1.010， 95%CI： 1.005‍ ‍—‍ ‍1.015， P<0.001）， and PLT （OR=0.997， 95%CI： 0.994‍ ‍—‍ ‍0.999， P=0.020） were the influential factors for MRLI. The areas under the ROC curve of ALP， GGT， and PLT were 0.589， 0.637， and 0.595， respectively， and the AUC of them combined was 0.837. ConclusionMale sex， ICU admission， comorbidity with gallbladder disease， increased ALP， increased GGT， and decreased PLT were influencing factors for MRLI， and a combination of factors has a better predictive value for the occurrence of MRLI.

Objective: To analyze the consumption frequency of major foods among Chinese children aged 6-17 years old, and to provide a basis for optimizing the dietary structure of children in China. Methods: Using data from the China Nutrition and Health System Survey and Application Program for Children 0-18 years old, 56 734 children aged 6-17 years old from North, Norththeast East, Central, South, Southwest and Northwest seven regions in China were selected for the study using stratified cluster random sampling from 2019 to 2021. A food frequency questionnaire was used to investigate the intake frequency of eight food groups in a month, including fresh vegetables, fresh fruits, livestock and poultry meats, aquatic products, eggs, dairy products, legumes, and cereals and potatoes. The foods were grouped according to whether they met the recommended intake criteria outlined in the Dietary Guidelines for Chinese Residents 2022. The〖KG*2〗χ2 test was used to compare the differences in the proportion of childrens intake frequency of each food group meeting the standard in different regions and age groups. Results: The proportions of Chinese children aged 6-17 years who consumed fresh vegetables and cereals and potatoes ≥3 times/d were 12.1% and 67.2%, respectively. The proportions of children who consumed fresh fruits, livestock and poultry meats, eggs and dairy products ≥1 time/d were 50.8%, 58.8%, 36.0% and 54.3%, respectively. The proportion of legumes consumed ≥4 times/week was 37.4%, and the proportion of aquatic products consumed ≥2 times/week was 39.7%. Fresh vegetables (5.5%), fresh fruits (33.1%), and dairy products (36.4%) had the lowest frequency of meeting the recommended standards in South China, and aquatic products (27.4%) and eggs (21.1%) had the lowest frequency of meeting the recommended standards in Northwest (P<0.008 3). Conclusion The overall intake frequency of fresh vegetables, fresh fruits, legumes, and dairy products are insufficient among Chinese children, with significant regional variations.

Objective: To analyze the association of eating dining locations and their association with nutritional status among Chinese children aged 6-17 years,so as to provide reference for guiding children s reasonable diet. Methods: Stratified random cluster sampling was used to select children aged 6 to 17 years from 28 cities and rural areas of 14 provinces in East, North, Central, South, Southwest, Northwest, Northeast of China, and a total of 52 535 children were included in the study from 2019 to 2021. Information including dining locations, demographic characteristics, dietary intakes and physical activity were collected through a questionnaire survey. Fasting body height and weight were measured in the morning. Unordered multiclass Logistic regression analysis was conducted to assess the relationship between dining locations and nutritional status in children. Results: Regarding children s dining locations, 66.3% ate breakfast at home,25.8% ate breakfast at school,7.9% ate breakfast outside (small dining tables, restaurants, stalls, etc.); 67.7% ate dinner at home,29.0% ate dinner at school,3.3% ate dinner outside; and 63.6% ate lunch at school,30.8% ate lunch at home,5.7% ate lunch outside. The prevalence rates of overweight/obesity and undernutrition were 28.6% and 9.3%, respectively. The adjusted multiclass Logistic regression analysis (controlling for age, region, parental education, household income, total energy intake, and moderate-to-vigorous physical activity) demonstrated that, compared to eating at home, school based breakfast and dinner consumption was associated with significantly lower overweight/obesity risks for both genders (boys: breakfast OR =0.70, 95% CI =0.65-0.75; dinner OR =0.80, 95% CI = 0.74- 0.86; girls: breakfast OR = 0.89 , 95% CI = 0.82-0.96; dinner OR =0.88, 95% CI =0.81-0.95), whereas eating lunch away from home significantly increased overweight/obesity risks (boys: OR =1.32, 95% CI =1.17-1.48; girls: OR =1.43, 95% CI =1.26- 1.62 ), with all associations being statistically significant ( P <0.05). After adjusting for confounding factors, boys who ate breakfast away from home showed a significantly reduced risk of undernutrition ( OR =0.80,95% CI =0.66-0.97), while those consuming lunch away from home had an increased risk ( OR =1.26, 95% CI =1.01-1.57) ( P <0.05). Conclusions The choice of dining locations for children is becoming more diverse, and a relatively high proportion of children eat meals outside the home and at school. Eating out have a higher risk of malnutrition for children. School feeding may be beneficial to children s physical health.

ObjectiveTo investigate the effect of Fuzheng Huayu prescription on hepatocyte extinction and regeneration in fibrotic liver and its mechanism of action in promoting hepatocyte regeneration. MethodsMice were given intraperitoneal injection of CCl₄ for 6 weeks to establish a model of liver cirrhosis， and there were 10 mice in the model group， 10 in the sorafenib group， 10 in the Fuzheng Huayu prescription group， and 9 in the normal control group. Since week 4 of modeling， the mice in the Fuzheng Huayu prescription group and the sorafenib group were given the corresponding drug by gavage at a dose of 4.8 g/kg and 4 mg/kg， respectively， for three consecutive weeks， and those in the normal group and the model group were given an equal volume of sodium carboxymethyl cellulose. Serum liver function parameters were measured； the METAVIR scoring system was used to evaluate liver inflammation and fibrosis stage； Sirius Red staining and hydroxyproline （Hyp） content in liver tissue were used to evaluate collagen deposition； immunohistochemistry was used to measure the protein expression levels of type IV collagen， CD31， CD32b， Ki67， CyclinD1， glutamine synthetase， Wnt2， and HGF， and Western blot was used to measure the expression levels of Wnt2， LRP6， β-catenin， p-β-catenin， and CyclinD1 in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the model group， the Fuzheng Huayu prescription group and the sorafenib group showed the following changes： significant reductions in the serum levels of alanine aminotransferase and aspartate aminotransferase and the content of Hyp in liver tissue （all P<0.01）； a significant reduction in METAVIR score； significant reductions in the expression levels of type Ⅳ collagen and CD31 （all P<0.05） and a significant increase in the expression level of CD32b （P<0.01）； significant reductions in the number of parenchymal extinction lesions and significant increases in the expression levels of Ki67 and CyclinD1 in liver tissue （all P<0.01）； significant increases in the protein expression levels of Wnt2， LRP6， β-catenin， and CyclinD1 and a significant reduction in the protein expression level of p-β-catenin （all P<0.05）； significant increases in the number of cells stained positive for both CD32b and Wnt2. ConclusionFuzheng Huayu prescription can inhibit hepatic sinusoidal capillarization， improve the Wnt2 exocrine function of liver sinusoidal endothelial cells， activate the Wnt/β-catenin signaling pathway associated with hepatocyte regeneration， and finally reverse liver cirrhosis.

ObjectiveTo observe the regulatory effect of Huangwu Ganfu ointment on transient receptor potential anchor protein 1 （TRPV1） receptor expression， macrophage polarization， and p38 mitogen-activated protein kinase （p38 MAPK） signaling pathway in synovial tissue of knee osteoarthritis （KOA） rats with yang deficiency and cold coagulation syndrome and explore the mechanism of relieving peripheral inflammatory hyperalgesia of KOA. MethodForty-eight male SD rats were randomly divided into blank group， model group， high-dose， middle-dose， and low-dose groups of Huangwu Ganfu ointment （9.3， 4.65， 2.325 g·kg^-1）， and celecoxib group （20.82 mg·kg^-1）. The KOA rat model of yang deficiency and cold coagulation syndrome was established through climate box and swimming for two weeks combined with an injection of sodium iodoacetate （MIA） in the articular cavity. After continuous administration for four weeks， the general condition of rats in each group was observed， and the pain withdrawal threshold （PWT） and joint diameter induced by mechanical stimulation were recorded. The expression levels of interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， nerve growth factor （NGF）， and calcitonin gene-related peptide （CGRP） inflammatory factor were detected by enzyme-linked immunosorbent assay （ELISA）， and the histopathological changes of synovial tissue of the knee joint were observed by hematoxylin-eosin （HE） staining. Western blot was used to detect the protein expression of TRPV1， p38 MAPK， and p-p38 MAPK in synovial tissue of the knee joint， and immunofluorescence （IF） was used to evaluate the polarization of M1/M2 macrophages. ResultCompared with that in the blank group， the overall mental state of the model group was worse， and the autonomous activity was decreased. The body mass was lower， and the joint diameter was increased. The X-ray showed that the osteophyte at the edge of the joint proliferated， and the articular surface was obviously rough. The articular cavity was significantly narrowed， and the PWT was significantly decreased （P<0.01）. The contents of IL-1β， TNF-α， CGRP， and NGF in serum and synovium Krenn score increased significantly （P<0.01）. The protein expression of TRPV1 and p-p38 MAPK/p38 MAPK increased significantly （P<0.01）， and the proportion of M1 macrophages and M1/M2 increased （P<0.01）， while the proportion of M2 macrophages decreased （P<0.01）. Compared with model group， the body mass in the low， middle， and high dose groups of Huangwu Ganfu ointment increased to different degrees （P<0.05， P<0.01）. The diameter of the knee joint in the high dose group of Huangwu Ganfu ointment and celecoxib group decreased （P<0.01）. The recovery of PWT in the high and middle dose groups of Huangwu Ganfu ointment groups was more obvious （P<0.05）. The contents of IL-1β and CGRP in the serum of rats in each administration group were significantly decreased （P<0.01）， and the content of serum TNF-α in the celecoxib group and high dose group of Huangwu Ganfu ointment decreased significantly （P<0.05）. The content of serum NGF in the middle dose group of Huangwu Ganfu ointment decreased significantly （P<0.05）， and the synovium Krenn score decreased in the high dose group of Huangwu Ganfu ointment （P<0.05）. In addition， the protein expression of TRPV1 and p-p38 MAPK/p38 MAPK in synovial tissue decreased significantly in all groups of Huangwu Ganfu ointment （P<0.01）. The proportion of M1 macrophages in synovial tissue in the celecoxib group and all groups of Huangwu Ganfu ointment decreased （P<0.01）， and the proportion of M2 macrophages in the high dose group of Huangwu Ganfu ointment increased （P<0.05）. The M1/M2 in the middle and high dose groups of Huangwu Ganfu ointment decreased （P<0.05）. ConclusionHuangwu Ganfu ointment can mediate the polarization of macrophages to reduce the inflammatory reaction of KOA， alleviate the release of inflammatory pain mediators， and lower the protein expression of TRPV1. The mechanism may be related to the p38 MAPK signaling pathway， so as to improve the peripheral hyperalgesia of KOA.

Objective:To analyze the relationship between body mass index (BMI) and fat mass percentage (FMP) in children aged 3-17 years in China.Methods:The BMI and FMP data of children aged 3-17 years from the National Nutrition and Health Systematic Survey in 0-18 years old children in China was analyzed. BMI- Z score/BMI and FMP were used to classify the subjects, respectively. Spearman correlation was used to analyze the correlation between BMI and FMP. The consistency between BMI- Z score/BMI and FMP in classifying the subjects was measured using Kappa coefficient. Results:The FMP of malnutrition, normal and overweight/obesity in boys was higher in age group 10-13-year than in other age groups (all P<0.001). The FMP of all nutritional status in girls increased with age (all P<0.05). The BMI of boys in all the FMP levels increased with age (all P<0.05). When the FMP of girls was 25%- or ≥30%, BMI increased with age (all P<0.001). The relationship between BMI and FMP was strong ( r=0.705, P<0.001), with r of 0.618 in boys and 0.884 in girls. The consistency between BMI- Z score/BMI and FMP in classifying the subjects was found to be moderate (Kappa=0.574, P<0.001). Conclusions:There was a strong relationship between BMI and FMP. The consistency between BMI- Z score/BMI and FMP in classifying the subjects was moderate.

Objective:To evaluate the consistency between bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) in the measurement of body composition in children aged 6-17 years in China.Methods:Fat-free mass, fat mass and fat mass percentage were measured by both BIA and DXA in 1 161 children. t-test or Wilcoxon paired test was used to evaluate the different outcome of the two methods. The correlation and consistency between the methods were evaluated by Spearman correlation coefficients ( r) and Bland-Altman analysis. Results:Body compositions measured by BIA was positively correlated with those measured by DXA (fat mass r=0.95, fat-free mass r=0.98, fat mass percentage r=0.86, all P<0.05). Comparing with DXA, BIA underestimate children's fat mass [the mean difference is -3.15 kg, and the SD is 2.35 kg, 95% limits of agreement (LoA): -7.74-1.45 kg] and fat mass percentage (the mean difference is -8.45%, and the SD is 4.63%, 95% LoA: -17.53%-0.64%). Conclusions:Body compositions measured by BIA was highly positively correlated with those measured by DXA. BIA has certain application value in the measurement of body fat mass and fat-free mass of children aged 6-17 years.

Objective To investigate the effect of day chemotherapy on medical expenses of breast cancer patients.Methods The medical expenses of breast cancer patients in the First Affiliated Hospital of Guangxi Medical Universtiy from January 2019 to September 2023 were retrospectively investigated.Interrupted time series analysis was used to analyze the changes and trend of medical expenses and expenses structure of breast cancer before and after the implementation of day chemotherapy.Results The number of 8066 cases with breast cancer were included in this study.After day chemotherapy,the total expenses and each expense detail decreased significantly(P＜0.001).The total expenses,medicine expense,examination expenses and other expenses showed an upward trend before implementation of day chemotherapy(P＜0.05),the laboratory expenses showed a downward trend before implementation of day chemotherapy(P＜0.001).The total medical expenses decreased by 7306.34 yuan immediately after the implementation of day chemotherapy.The expenses of laboratory test,treatment,examination,nursing,medicine,health materials and other expenses were decreased by 599.59 yuan,1674.34 yuan,1470.66 yuan,91.37 yuan,3473.91 yuan,231.51 yuan and 436.73 yuan,respectively.Conclusion The implementation of day chemotherapy for breast cancer has significantly reduced all kinds of costs,which is conductive to reducing disease burden of patients.
