ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan， excavate and analyze the key information of Xieqingwan， and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition， dosage， decocting methods， usage， and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows： Angelicae Sinensis Radix， Gentianae Radix et Rhizoma， Chuanxiong Rhizoma， Gardenia seeds， Radix et Rhizoma Rhei， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix were grounded to fine powder， decocted with honey， and finally formed into pills with the size of a chicken head （1.5 g）. It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology， neurology， dermatology， digestion， and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity， removing fire and relaxing the bowels， and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan， which is often modified and used in treating Tourette syndrome， herpes， febrile convulsion， sleepwalking， and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan， induces its historic evolution， and confirms its key information， so as to provide a reference for the future development of Xieqingwan.

Background The decline of physical activity in the elderly due to aging may increase the risk of sarcopenia. Currently, there is a lack of evidence from large natural populations on the relationship between PA and sarcopenia. Objective To explore the relationship between PA and sarcopenia in the elderly aged 60 years and above in 10 provinces (autonomous regions) of China. Methods Data were retrieved from the 2022—2023 round of the China Development and Nutrition Health Impact Cohort. Personal basic information and PA data were collected by questionnaire survey. Skeletal muscle mass was measured by bio-electrical impedance analysis, muscle strength was measured using a grip dynamometer, and physical performance was reflected by 6-meter walk speed. The Asian Working Group for Sarcopenia (AWGS) 2019 criteria were used to diagnose sarcopenia. Light physical activity (LPA) duration, moderate-to-vigorous physical activity (MVPA) duration, and total physical activity volume were calculated. A total of 3326 residents aged ≥60 years with complete data were selected as the survey participants. Multiple logistic regression models and restricted cubic splines (RCS) were used to assess the association between PA duration/volume and sarcopenia. Results In 10 provinces (autonomous regions) of China, the prevalence of sarcopenia in the elderly aged 60 years and above was 5.5% (95%CI: 4.7%, 6.2%). The logistic regression analysis showed that compared with the elderly reporting 0-7.0 h·week⁻¹ in LPA duration, the risk of sarcopenia in the elderly with LPA duration of >14.0-21.0 h·week⁻¹ was reduced by 51% (OR=0.49, 95%CI: 0.26, 0.96). Compared with the elderly with total physical activity ≥15.0 metabolic equivalent of task (MET)-h·week⁻¹, those with <7.5 MET-h·week⁻¹ had a 2.24-fold increased risk of sarcopenia (OR=2.24, 95%CI: 1.17, 4.29). The RCS results found that LPA duration and total physical activity volume each showed a nonlinear dose-response relationship with the risk of sarcopenia (P_overall<0.05, P_non-linear<0.05). Compared with the elderly with an LPA duration of 0 h· week⁻¹, the risk of sarcopenia in the elderly with an LPA duration of 12.6 h· week⁻¹ was the lowest (OR=0.42, 95%CI: 0.21, 0.83). Compared with the elderly with a total physical activity volume of 15.0 MET-h· week⁻¹, the elderly with a total physical activity volume of 46.0 MET-h· week⁻¹ had the lowest risk of sarcopenia (OR=0.57, 95%CI: 0.38, 0.84). There was no statistically significant association between weekly MVPA duration and the risk of sarcopenia (P>0.05). Conclusion Increasing weekly LPA duration and total physical activity volume would help to reduce the risk of sarcopenia.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.

OBJECTIVE To investigate the efficacy and safety of hetrombopag combined with low-dose prednison in the treatment of patients with refractory/recurrent primary immune thrombocytopenia(ITP). METHODS A total of 40 patients with ITP who failed to respond to previous treatment or relapsed in the Department of Hematology of Gansu Provincial People’s Hospital From July 2021 to August 2022 were selected. Used randomized controlled trial research methods, according to the treatment plan, they were divided into observation group and control group, with 20 cases in each group. The control group was treated with low-dose prednison alone. The observation group was combined with hetrombopag treatment on this basis. The efficacy and adverse reactions were compared between the two groups. RESULTS Treatment 6 weeks, patients who's proportion of platelet counts(PLT) reached≥50×109·L−1 and ≥30×109·L−1 in observation group were higher than control group with statistically significant differences in both groups[90%(18/20) vs 50%(10/20), P＝0.006; 90%(18/20) vs 65%(13/20), P＝0.130]; The study also indicated a statistically significant difference in favour of observation group compared with control group in the odds of achieving the outcome of a PLT≥50×109·L−1at least once during 6-week treatment[90%(18/20) vs 55%(11/20), P＝0.147], was more than placebo-treated one. The median time of PLT ≥ 50×109·L−1 for the first time within 6 weeks of treatment in the observation group was 3 weeks, which was the same as that in the control group. After 6 weeks of treatment, the median platelet count in the observation group was higher than that in the control group[97.50(58.25−166.75)×109·L−1 vs 45.50(13.25−82.50)×109·L−1 , P<0.05]. The median PLT count in the observation group was higher than that in the control group at week 1−6 after treatment, and the curative effect was significant. The two groups of patients tolerated the regimen well, and the degree of adverse reactions was mild, which improved quickly after symptomatic treatment. CONCLUSION Hetrombopag combined with low-dose prednison has a high effective rate in the treatment of refractory/recurrent ITP, which is better than that of single use, and the adverse reactions are tolerable, so it can be widely used in clinical practice.

Objective:To investigate the correlation between macular cherry red spot (CS) and severity of neurological manifestations in Chinese children with sialidosis (SD) type I.Methods:A evidence-based medical study. "China", "Sialidosis" and "Sialidoses" were used as Chinese and English search terms. The literature was searched in CNKI, Wanfang and PubMed. The cases were all from China and matched the diagnostic criteria. According to the presence or absence of CS in the fundus, the SD children were divided into a group with CS (+) and a group without CS (-), and the correlation between the occurrence of ocular CS and neurological manifestations was compared with meta-analysis by RevMan 5.3 software.Results:Sixty-eight studies were initially retrieved according to the search strategy, and 17 studies were finally included, and 5 studies with CS+ and CS- were meta-analyzed. Among the 43 patients, 28 were male and 15 were female, with a median age of 12 years. Visual impairment was observed in 37 cases (90.2%, 37/41, 2 cases not recorded), and CS was present in 24 cases (55.8%, 24/43). The most common neurological manifestation was myoclonus (97.7%, 42/43), followed by cerebellar ataxia (95.1%, 39/41, 2 cases not recorded) and seizures (91.4%, 32/35, 8 cases not recorded). Pathogenic NEU1 gene mutations were detected in 42 cases and one case was undocumented. The incidence of seizure in group CS+ (100%, 20/20) was higher than that in group CS- (80%, 12/15). Meta-analysis showed that there was no statistically significant difference between the incidence of myoclonus or ataxia [relative risk ( RR)=1.13, 95% confidence interval ( CI) 0.79-1.63, P=0.49] and seizure ( RR=1.13, 95% CI 0.84-2.06, P=0.24) among the children in the CS+ and CS- groups. Conclusions:The incidence of ocular CS in Chinese children with type I SD was 55.8%. There was no correlation with neurological manifestations, however the incidence of seizure was significantly higher in patients with CS than in others without CS.

Objective:To explore the effect of intervention model based on comprehensive nutrition management on glucose and lipid metabolism and pregnancy outcome in patients with gestational diabetes mellitus (GDM).Methods:104 GDM patients admitted to Shanxi Bethune Hospital from February 2022 to March 2023 were randomly divided into control group and experimental group, with 52 cases in each group. The control group implemented routine management measures and nutrition guidance, while the experimental group implemented an intervention model based on comprehensive nutrition management on the basis of routine management. The indexes of glucose and lipid metabolism (glycosylated hemoglobin, fasting blood glucose, 2 h postprandial blood glucose, total cholesterol, triglyceride and low density lipoprotein cholesterol), pregnancy outcome, self-management ability and self-efficacy were compared between the two groups before and after intervention.Results:Before the intervention, there was no significant difference in general situation, glucose and lipid metabolism index, self-management ability and self-efficacy between the two groups ( P>0.05). After the intervention, the level of glucose and lipid metabolism index in the experimental group was significantly lower than that in the control group, with statistical significance ( P<0.05). The incidence of adverse pregnancy outcome in the experimental group was significantly lower than that in the control group, with statistical significance ( P<0.05). The scores of self-management ability and self-efficacy in the experimental group were significantly higher than those in the control group, with statistical significance ( P<0.05). Conclusion:The intervention model based on comprehensive nutrition management can effectively improve the glucose and lipid metabolism index and pregnancy outcome of GDM patients, and significantly improve their self-management ability and self-efficacy related to nutrition management, which has high clinical application and promotion value.

Objective:To investigate the morbidity of cerebrovascular disease among residents ≥30 years in Pengzhou, Sichuan Province, and analyze the effect of physical activity level on the risk of morbidity of cerebrovascular disease.Methods:From 2004 to 2008, people from Pengzhou, Sichuan Province were randomly selected. All the local people aged 30-79 were asked to receive a questionnaire survey, physical examination, and long-term follow-up to determine the morbidity of cerebrovascular disease. The physical activity level and the morbidity of cerebrovascular disease were described, and Cox proportional hazard regression models were used to evaluate the association of domain-specific physical activity with the risk of morbidity of cerebrovascular disease.Results:In 55 126 participants, there were 5 290 new cases of cerebrovascular disease, with a cumulative incidence of 9.60%. After the adjustment for multiple confounding factors, multivariate Cox proportional hazard regression analysis showed that increased levels of occupational, transportation, and total physical activity reduced the risk of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). The highest group of occupational physical activity level had the lowest risk of cerebrovascular disease, with a hazard ratio ( HR) value of 0.81 (95% CI: 0.75-0.88), the highest group of transportation physical activity level had the lowest risk of cerebrovascular disease, with an HR value of 0.84 (95% CI: 0.78-0.91), the highest group of total physical activity level had the lowest risk of cerebrovascular disease, with an HR value of 0.87 (95% CI: 0.80-0.94), compared with the lowest group of corresponding physical activity. No association was found between the household/leisure-time physical activity level and the risk of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). Conclusions:In project areas of Pengzhou, Sichuan Province, increased physical activity has been associated with reduced morbidity of cerebrovascular disease and its subtypes (cerebral hemorrhage, cerebral infarction). Increased levels of physical activity in adults are encouraged for health benefits.

Objective:To prepare seven standard strains of 2019 novel coronavirus (2019-nCoV), including wild type (WT) strain, Beta variant, Delta variant, Omicron variants (BA.2, BA.5, BQ.1, XBB.1 branches), which could be used to apply for national standard strains.Methods:According to cytopathic effect (CPE), virus titer, whole-virus-genome-sequencing and detection of mycoplasma, the basic biological characteristics of clonal isolation were determined through plaque purification technology.Results:The CPE was mainly characterized by cell shrinkage and exfoliation in Vero cells after infection with seven 2019-nCoV clonal isolations (WT, Beta, Delta, Omicron, BA.2, BA.5, BQ.1 and XBB.1 branches). The result of mycoplasma detection were negative and titers of the clonal isolation from 2nd to 5th generations were stable at 10 5-10 8 TCID 50/ml; the electron microscope showed that the virions were all round or elliptical, with a diameter between 60 nm and 140 nm. The subtypes of 7 strains were identified by whole-virus-genome-sequencing and phylogenetic analysis, with genomic stability after the fifth successive generations of clonal isolation. Conclusions:The series clonal isolation of 2019-nCoV with typical CPE of coronavirus, clear morphological structure, good viral activity and stable genetic characteristics were prepared, and they could be used to apply for national standard strains.

Objective:To investigate the variation of reference ranges of hemodynamic parameters in normal pregnancy and their relation to maternal basic characteristics.Methods:A total of 598 healthy pregnant women who underwent regular prenatal examination at the Third Affiliated Hospital of Guangzhou Medical University from January to December 2023 were prospectively enrolled, and noninvasive hemodynamic monitors were used to detect changes in hemodynamic parameters of the pregnant women with the week of gestation, including cardiac output (CO), stroke volume (SV), thoracic fluid content (TFC), systemic vascular resistance (SVR), mean arterial pressure (MAP), and heart rate (HR). Relationships between hemodynamic parameters and maternal basic characteristics, including age, height, and weight, were analyzed using restricted cubic spline.Results:(1) CO ( r=0.155, P<0.001), TFC ( r=0.338, P<0.001), MAP ( r=0.204, P<0.001), and HR ( r=0.352, P<0.001) were positively correlated with the week of gestation, and SV was negatively correlated with the week of gestation ( r=-0.158, P<0.001). There was no significant correlation between SVR and gestational age ( r=-0.051, P=0.258). (2) CO exhibited a positive correlation with maternal height and weight (all P<0.001). The taller and heavier of pregnant women, the higher their CO. A linear relationship was observed between maternal weight and SV, MAP and HR (all P<0.01). As maternal weight increased, SV, MAP and HR showed an upward trend. Furthermore, there was an inverse association between maternal age and SVR ( P<0.001). (3) There was a significant nonlinear association observed between TFC and body mass index during pregnancy ( P<0.05). Additionally, a nonlinear relationship was found between SVR and MAP in relation to maternal age (all P<0.05). Notably, when the age exceeded 31 years old, there was an evident upward trend observed in both SVR and MAP. Conclusions:The hemodynamic parameters of normal pregnant women are influenced by their height, body weight, and age. It is advisable to maintain a reasonable weight during pregnancy and give birth at an appropriate age.

Objective To analyze the hot spots,rules and distribution on safety research of inhalation preparations at home and abroad in the past 20 years,and to summarize the current status of safety and risk control research on inhalation preparations.Methods This reaserch is based on the literature related to the safety and risk control of inhalation preparations in the core collection database of the Web of Science.With the help of Excel 2021 and CiteSpace6.1.R3,visualized processing and analysis were carried out on the annual number of publications,countries,institutions,authors,co-occurrence of keywords,clustering and prominence.Results A total of 365 articles were included,the annual publication number in the field of the safety and risk control of inhalation preparations was less than 30 per year from 2002 to 2018.But since 2019,the number of articles published this year has exceeded 30.Through the analysis of the cooperation network of countries and institutions,the top four countries in terms of publication volume are the United States,the United Kingdom,Germany,and China,and the top three institutions are AstraZeneca,GlaxoSmithKline and Pfizer.Through the analysis of the author cooperation network,the cooperation network between European and American authors was formed earlier,and a certain research group has appeared in 2002.In contrast,a more concentrated cooperation network has been formed in China in 2020.Conclusions In the past 20 years,the research on inhalation preparations has mainly focused on their safety and efficacy,while there are few studies on their risk control.There is a disconnect between safety assessment and risk assessment,and the future focus maybe focused on the adverse reaction assessment and risk management research of inhalation preparations.
