ObjectiveA qualitative analysis method was established for the composition of Astragali Radix(AR) before and after rice stir-frying. On the basis of systematic characterization of the chemical compositions in AR and stir-fried AR with rice(ARR), the structures of their major compounds were deduced and identified, and the differential compositions between them were analyzed. MethodsUltra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS) was used to detect the samples of AR and ARR in positive and negative ion modes, respectively. The compounds were analyzed and identified through self-constructed databases, literature, and reference standards, etc. And the data were analyzed by chemometrics, in order to screen for the differential components between AR and ARR. ResultsA total of 123 compounds were identified in AR and ARR, including 41 flavonoids, 19 terpenoids, 26 organic acids, 8 amino acids, 5 nucleotides, 5 carbohydrates and 19 other compounds. Among them, there were 95 common components in both, 18 unique components in AR, and 10 unique components in ARR. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) results both showed that there were significant differences in the chemical constituents of AR before and after rice stir-frying, and a total of 26 constituents with differences in the content were screened out, including L-canavanine, L-pyroglutamic acid, L-phenylalanine, cis-caffeic acid, and malonylastragaloside Ⅰ. Among them, 19 constituents of ARR were down-regulated and 7 constituents were up-regulated by comparing with AR. ConclusionThis study clarifies that the chemical composition of AR and ARR is mainly composed of flavonoids, terpenoids, and organic acids, and analyzes the components with significant differences in content between the two in combination with chemometrics, and the differential components are dominated by amino acids, organic acids and terpenoids, which can provide reference for the subsequent quality control and material basis research.

Objective:To understand the pathogen distributions of community-acquired pneumonia (CAP) in children, and to provide evidence for clinical diagnosis and treatment.Methods:The hospitalized children with CAP in Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January to December 2022 were selected as the research subjects. They were divided into infant group (28 d to less than one year), toddler group (one year to less than three years), preschool age group (three years to less than six years), and school age group (not less than six years) by age. According to the onset season, they were divided into spring group (February to April), summer group (May to July), autumn group (August to October), and winter group (January, November to December). Deep airway sputum samples were collected from all patients for bacterial culture identification. Respiratory viruses (influenza A virus (IVA), influenza B virus (IVB), respiratory syncytial virus (RSV), adenovirus, parainfluenza virus type 1 (PIV1), parainfluenza virus type 2 (PIV2), parainfluenza virus type 3 (PIV3)) were detected using direct immunofluorescence assay. Mycoplasma pneumoniae (MP) DNA was detected using fluorescent quantitative polymerase chain reaction, and particle agglutination was used to detect serum MP antibodies. Statistical analysis was performed using the chi-square test. Results:Among the 397 cases of CAP in children, pathogens were detected in 269 cases, with a positivity rate of 67.8%. A total of 309 pathogens were identified, including 204 strains of MP (66.0%), 60 strains of bacteria (19.4%), 42 strains of viruses (13.6%), and three strains of fungi (1.0%). Staphylococcus aureus (19 strains), Haemophilus influenzae (15 strains) and Streptococcus pneumoniae (five strains) were the predominant bacteria, while RSV (19 strains) and PIV3 (nine strains) were the main viruses. The distribution rates of MP, bacteria, and viruses showed statistically significant differences among different age groups ( χ2=99.82, 24.71 and 17.40, respectively, all P<0.05). MP infection was mainly observed in the preschool age group and school age group, and bacterial infection predominantly occurred in the infant group, and viral infection was most common in the toddler group. Among virus infected patients, RSV was detected in the toddler group and the preschool age group, while three cases of PIV3 cases were found in children over five years old. The distribution differences of MP, bacterial and viral infections between different seasons were statistically significant ( χ2=141.65, 20.44 and 31.87, respectively, all P<0.001), with a higher prevalence in winter. RSV infections demonstrated a clear seasonal trend, with 16 cases of RSV infections occurring in winter and spring. Conclusions:MP is the most frequently detected pathogen in children with CAP. Bacterial infection is the most common pathogen in infants with CAP. RSV is the most common viral pathogen, with infections concentrated in the toddler group and the preschool age group, and prevalence in winter and spring. Attention should be paid to PIV3 pneumonia in children over five years old. Rational drug use should be based on the pathogen spectrum characteristics of different seasons and age groups before selecting empirical treatment combinations.

OBJECTIVE To study the improvement effect and mechanism of Shuhou tongqi formula on intestinal injury in mice with postoperative ileus (POI). METHODS Mice were randomly divided into sham operation group, model group, positive control group (Mosapride citrate tablets, 1.95 mg/kg), and Shuhou tongqi formula group (1.88 g/kg), with 6 mice in each group. Except for the sham operation group, POI model was induced in other groups by typical small intestinal interference. Each group was given relevant drug liquid/water, once a day, for consecutive 2 days. After the last medication, the percentage of carbon powder propulsion in small intestine was detected, and pathomorphological changes in ileum tissue of mice were observed. The serum levels of interleukin-6 (IL-6), IL-10, tumor necrosis factor-α (TNF-α), motilin (MTL) and somatostatin (SS) were all detected; the expression levels of Toll-like receptor 4 (TLR4), nuclear factor κB (NF-κB p65) and p38 mitogen-activated protein kinase (p38 MAPK) were determined in ileal tissue of mice; the gut microbiota of colon contents was analyzed in each group of mice. RESULTS After the intervention of Shuhou tongqi formula, pathological damage such as intestinal wall atrophy and mucosal capillary congestion in ileum tissue were improved significantly; the percentage of carbon powder propulsion and the serum level of IL-10 and MTL were increased significantly (P<0.05); however, serum levels of TNF-α, IL-6 and SS, the expressions of TLR4, NF-κB p65 and p38 MAPK were decreased significantly (P<0.05). The analysis of gut microbiota showed that Shuhou tongqi formula could significantly increase ACE, Chao1, Shannon and PD indexes, and relative abundance of Akkermansia (P<0.05), but decreased relative abundance of Proteobacteria, Ligilactobacillus and Escherichia-Shigella significantly (P<0.05). CONCLUSIONS Shuhou tongqi formula can improve intestinal injury and inflammatory reaction of POI mice, the mechanism of which may be associated with inhibiting the activity of TLR4/ NF-κB/MAPK signaling pathway, regulating the levels of gastrointestinal hormones and improving the disturbance of intestinal flora in mice.

【Objective】 To investigate the factors influencing the length of hospital stays of the acute fatty liver of pregnancy (AFLP) patients, so as to establish the prediction model. 【Methods】 A total of 49 patients diagnosed as AFLP)in ShenZhen People’s Hospital between January 2008 and January 2023 were retrospectively analyzed. According to the median length of hospital stays, the patients were divided into two groups: Group A(n=21)and Group B(n=28). Preoperative general laboratory data, clinical features and postpartum adverse outcomes in both groups were analyzed. Multivariate binary logistic regression was used to analyze the independent factors affecting the length of hospital stays for AFLP, and a prediction model for hospitalization time was established. 【Results】 Comparison between Group B and Group A were as follows: hospital stays(d)(15.5 vs 8), preoperative icterus(%)[16(57.1%)vs 3(14.3%)], thrombin time(TT)(s)(24.2 vs 21.3), prothrombin time(PT)(s)(16.8 vs 15.3), activated partial thromboplastin time(APTT)(s)(52.3 vs 40.7), total bilirubin(TBIL)(μmol/L)(77.2 vs 45.2), indirect bilirubin(IBIL)(μmol/L)(21.2 vs 10), creatinine(Cre)(μmol/L)[(171.97±53.34) vs (131.81±45.06]), TT extension(%)[24(85.7%)vs 11(52.4%)], APTT extension(%)[27(96.4%)vs 7(33.3%)], IBIL elevation(%)[19(67.9%)vs 4(19%)], Cre concentration rise(%)[21(75%)vs 8(38%)], number of postpartum plasma exchange sessions(%)[23(82.1%)vs 5(23.8%)], postpregnancy co-infection phenomenon(%)[21(75%)vs 4(19%)], with Group B significantly higher than Group A. The preoperative platelet count(×109/L)(128 vs 221)and the concentration of fibrinogen(g/L)[0.9 vs 1.6] in Group B were significantly lower than those in Group A. Univariate logistic regression analysis showed that preoperative icterus, postpregnancy co-infection phenomenon, number of postpartum plasma exchange sessions, preoperative TT extension, preoperative APTT extension, Cre concentration rise were influencing factors for the hospital stays of AFLP patients. According to the minimum result of Akaike information criterion, the multivariate binary logistic regression analysis (step-wise selection) showed that the number of postpartum plasma exchange sessions, icterus, preoperative APTT extension were the independent risk factor influencing the hospital stays of AFLP patients, and the logistic regression prediction model was established by incorporating the above three factors. Regularization techniques were further employed in linear regression to address and assess overfitting issues. Additionally, the confidence interval for the estimated effect sizes in each model have been acquired by bootstrapping techniques. 【Conclusion】 Preoperative icterus, preoperative APTT extension(APTT>43s)and the number of postpartum plasma exchange sessions were the independent risk factor influencing the hospital stays of AFLP patients and the logistic regression prediction model with high predictive effectiveness was established successfully.

OBJECTIVE To analyze the odor composition changes of two kinds of traditional Chinese medicine sachet (children type and adults type) with different placement time by using ultra-fast gasphase electronic nose technology. METHODS The change rule of sachet components at different storage times was analyzed by gas chromatography. At the same time, the qualitative results were obtained by combining electronic nose with Arochembase database. Discriminant factor analysis was used to analyze the overall odor composition differences of the two sachet samples. RESULTS A total of 10 odor compositions were identified in children-type sachet, including α-pinene and β-pinene as the functional index compositions; five odor compositions of children-type sachet disappeared after 0.25 days, and most of them disappeared after 7 days; the cumulative contribution rate of discriminant factor analysis was 99.225%. A total of 8 odor compositions were identified in adult-type sachets, including α-pinene and α-phellandrene as the functional index compositions; four odor components disappeared after the adult-type sachet was placed for 0.25 days; after 15 days of placement, the peak 6-8 disappeared, and the intensity of peak 5 decreased by 34.3% compared with 0 day of placement; the cumulative contribution rate of discriminant factor analysis was 91.965%. CONCLUSIONS With the extension of storage time, the smell and composition of the two traditional Chinese medicine sachets are decreasing. It is recommended that the use time of children-type sachet is 7 days, and that of adult-type sachet is 15 days.

OBJECTIVE To explore the mechanism of Kuaisong yin in the prevention and treatment of constipation. METHODS Slow transit constipation (STC) model was established with Compound difenoxylate tablet in mice and rats. Two batches of mice were divided into blank group, model group, positive control group (Maren soft capsule, 0.64 g/kg), Kuaisong yin low-dose, medium-dose and high-dose groups (3.2, 6.4, 12.8 g/kg), with 10 mice in each group. The effect of Kuaisong yin on constipation in mice was evaluated by intestinal propulsion experiment and defecation experiment. Rats were divided into blank group, model group, positive control group (Maren soft capsule,0.36 g/kg), Kuaisong yin low-dose and high-dose groups (2.4, 4.8 g/kg), with 7 or 8 rats in each group. They were given relevant medicine once a day for 1 week. The metabonomics of serum and urine of rats were analyzed by UPLC-Q-TOF-MS/MS technology. RESULTS Compared with model group, the ink propulsion rate and 5 h defecation volume of mice in Kuaisong yin high-dose group were significantly increased (P<0.05); the first defecation time of mice in Kuaisong yin medium-dose and high-dose groups was significantly shortened, and the quality of defecation was significantly reduced within 5 h (P<0.05 or P<0.01). Serum metabonomics screened 16 compounds (such as proline, propionylcarnitine, hemolytic phosphatidylcholine, etc.) and 6 metabolic pathways (such as sphingomyelin metabolism, arginine and proline metabolism, sphingolipid biosynthesis-lactose and neolactone series). Urine metabonomics screened 20 different metabolites (such as prostaglandin A2, L-valine, phosphatidylcholine, sphingomyelin, etc.) and 8 metabolic pathways (such as valine, leucine and isoleucine biosynthesis, sphingomyelin metabolism, pyruvate metabolism, etc.). CONCLUSIONS Kuaisong yin can play a role in improving constipation by regulating different metabolites such as hemolytic phosphatidylcholine, phosphatidylcholine, prostaglandin A2, L-valine, proline, and regulating metabolic pathways such as multiple amino acid metabolism, sphingomyelin metabolism, etc.

The insomnia model was established by chronic unpredictable mild stress combined with 4-chloro-DL- phenylacetic acid. The behavioral changes of mice were investigated through open field test and pentobarbital sodium synergistic hypnosis experiment, as well as the pathomorphology of mice hypothalamus tissue was observed by HE staining. The metabonomics analysis and multivariate statistical analysis of serum in mice were performed by UHPLC-Q-TOF-MS/MS, and the differential metabolites were screened out; the metabolic pathway analysis was conducted based on MetaboAnalyst 5.0 database. RESULTS Compared with blank group, the total travelling distance, the number of entering the central region and the moving distance in the central region of the model group were significantly reduced (P<0.05), the proportion of total rest time was significantly increased (P<0.05), the sleep duration of mice was significantly shortened (P<0.05), and hypothalamic nerve cells damaged and severely vacuolated. Compared with model group, the total travelling distance of Compound zaoren granule low-dose and medium-dose groups were increased significantly and the proportions of total rest time of those groups were decreased significantly (P<0.05), and the sleep duration of mice in Compound zaoren granule high-dose group was prolonged significantly (P<0.05); the hypothalamic nerve cells of mice in each administration group recovered to varying degrees, and the hypothalamus histiocytes of mice in the Compound zaoren granules high-dose group were closer to those in the blank group. A total of 18 differential metabolites (such as phenylalanine, taurine, norvaline, methionine) and 4 important amino acid metabolic pathways (L-phenylalanine, tyrosine and tryptophan biosynthesis; taurine and hypotaurine metabolism; L-phenylalanine metabolism; cysteine and methionine metabolism) were identified through metabolomics analysis. CONCLUSIONS Compound zaoren granules can normalize the disordered metabolism in vivo by regulating differential metabolites such as phenylalanine, taurine, and four amino acid metabolic pathways, so as to improve insomnia.

Ginkgo biloba preparation is widely used as natural extract preparation both domestically and internationally, for myocardial infarction and cerebral infarction diseases in China; and mainly used to improve memory and treat dementia symptoms abroad. In recent years, there have been a large amount of reports on the treatment of ophthalmic diseases, mental diseases, kidney diseases and so on, however some of which have not uniform literature result. Therefore, it is necessary to summarize the reports on off-label use of Ginkgo biloba preparation. Among them, Ginkgo biloba preparation has a lot of controversy on brain diseases such as dementia and autism, mainly due to the mild effect, the difficulty in tracking long-term medication data for chronic diseases, and the subjective evaluation results of cognitive level, so more high-level research is needed to provide data support. In addition, Ginkgo biloba preparation has obvious protective effects on peripheral nerves and microvascular, and as an adjuvant drug in related diseases, it can effectively accelerate the recovery process of patients. This article summarizes various reports on Ginkgo biloba preparations, which can better clarify the product positioning and provide a reference for the selection of relevant treatment options.

【Objective】 To strengthen the management of transfusion adverse events, so as to reduce the occurrence of medical damage and accidents, and guarantee the safety of blood transfusion. 【Methods】 The adverse events of blood transfusion reported in our hospital from July 2016 to December 2022 were collected, the reasons were tracked, and continuous improvements were made. 【Results】 From 2016 to 2022, a total of 315 transfusion adverse events were reported, including 233(73.97%, 233/315) cases of transfusion reactions and 82(26.03%, 82/315) transfusion adverse events. There were 271 328 transfusion cases in the same period, and the incidence of transfusion reactions was 0.858 7‰(233/271 328). The number of transfusion application was 129 887, and the incidence of transfusion adverse event is 0.631 3‰(82/129 887). Sixty-eigtht(82.93%, 68/82) cases of transfusion adverse events were caused by human factors, while the other 14(17.07%, 14/82) cases were non-human factors. According to the linear regression analysis, we have concluded that the year is a significant indicator for transfusion reaction rates (P<0.05), but not for transfusion adverse event rates (P>0.05). 【Conclusion】 Strengthening the management of reporting adverse events in clinical blood transfusion, monitoring the incidence, analyzing and improving different types of adverse events by management tools can reduce the medical risks of blood transfusion and help to guarantee the safety of clinical blood transfusion.
