Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage （Shang Han Lun）. This prescription is composed of Bupleuri Radix， Scutellariae Radix， Cinnamomi Ramulus， Zingiberis Rhizoma， Trichosanthis Radix， Ostreae Concha， and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang， warming the spleen， and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis （CC）， irritable bowel syndrome， and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain， poor appetite， postprandial fullness， aversion to greasy food， soft stool， and bitter mouth， being a type of biliary dyspepsia. In modern medicine， dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation， promoting the function of gallbladder， resolving stones， alleviating spasms， and relieving the pain for CC， demonstrating definite short-term efficacy but suffering from single effects， high recurrence rate， and poor compliance. Although surgical treatment can cure cholecystitis， it is accompanied by the increased incidence of adverse events such as abdominal pain， diarrhea， and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins， baicalin， cinnamaldehyde， gingerol， Trichosanthis Radix polysaccharide， Ostreae Concha polysaccharide， and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses， improving gallbladder contraction and gastrointestinal motility， regulating the bile acid-intestinal flora axis and the brain-gut axis， and modulating blood lipids through multiple targets. By reviewing the previous literature， this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

Objective: To determine the association between exposure to entertainment screen content on mobile phones and symptoms of anxiety-depression co-morbidity among college students,so as to provide evidence for mental health interventions. Methods: A baseline survey was conducted from April to May 2019. A total of 1 135 college students were selected from one university each in Shangrao City, Jiangxi Province and Hefei City, Anhui Province using cluster random sampling method. A follow up study was conducted in November 2019, resulting in 1 110 matched valid responses. Self rating questionnaires were used to assess the exposure of entertainment screen content. The Depression Anxiety Stress Scale-21(DASS-21) and the Patient Health Questionnaire-9 (PHQ-9) were used to evaluate the anxiety symptoms, depressive symptoms, and symptoms of anxiety-depression co-morbidity among college students. A multivariate binary Logistic regression model was constructed following initial intergroup comparisons with Chi-square test to determine the association between baseline exposure to mobile entertainment screen content and the risk of symptoms of anxiety depression co-morbidity at baseline and the 6 month follow up. Results: The prevalence rates of symptoms of anxiety-depression co-morbidity among college students were 25.4% and 20.6% at baseline and follow up, respectively.After adjusting for confounding factors such as gender, self rated family economic status and self rated health status, the results of multivariate binary Logistic regression analysis showed that compared with the appropriate exposure level group, the exposure of entertainment screen content on mobile phones at baseline, including frequent exposure to reading( OR =1.65,95% CI =1.14-2.39), occasional exposure to other entertainment screen content ( OR =1.46,95% CI =1.01-2.10)and frequent exposure to other entertainment screen content( OR =1.76,95% CI =1.20-2.60), increased the co-occurrence risk of symptoms of anxiety-depression co-morbidity among college students during the follow up period (all P <0.05). Conclusion Occasional or frequert exposure to mobile entertainment screen content can increase the risk of symptoms of anxiety depression co-morbidity among college students.

[Objective] To analyse and predict the tendencies of using erythrocyte blood in Changsha based on the autoregressive integrated moving average (ARIMA) model, long short-term memory (LSTM) and ARIMA-LSTM combination model, so as to provide reliable basis for designing a feasible and effective blood inventory management strategy. [Methods] The data of erythrocyte usage from hospitals in Changsha between January 2012 and December 2023 were collected, and ARIMA model, LSTM model and ARIMA-LSTM combination model were established. The actual erythrocyte consumption from January to May 2024 were used to assess and verify the prediction effect of the models. The extrapolation prediction accuracy of the models were tested using two evaluation indicators: mean absolute percentage error (MAPE) and root mean square error (RMSE), and then the prediction performance of the model was compared. [Results] The RMSE of LSTM model, optimal model ARIMA(1,1,1)(1,1,1)12 and ARIMA-LSTM combination model were respectively 5 206.66, 3 096.43 and 2 745.75, and the MAPE were 18.78%,11.54% and 9.76% respectively, which indicated that the ARIMA-LSTM combination model was more accurate than the ARIMA model and LSTM model, and the prediction results was basically consistent with the actual situation. [Conclusion] The ARIMA-LSTM model can better predict the clinical erythrocyte consumption in Changsha in the short term.

Objective: To assess the epidemiological, drug resistance, and their relative risk and prevalence for yielding clinical diseases ofStreptococcus mitisgroup(SMG) bloodstream infections in recent years. Methods : A total of 50 blood culture specimens were collected from patients with SMG bloodstream infection. These SMG isolates were identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry(MALDI-TOF MS). The susceptibility to antibiotics was tested by minimal inhibitory concentrations and Kirby-Bauer(K-B) disk diffusion methods. The data were comprehensively analyzed by statistical software combined with clinical data. Results : Five strains were identified in SMG bloodstream infection by mass spectrometry, namelyStreptococcus oralis/mitis(S.oralis/mitis),Streptococcus pneumonia(S.pneumonia),Streptococcus gordonii(S.gordonii),Streptococcus sanguinis(S.sanguinis), andStreptococcus parasanguinis. These SMG showed high resistance to erythromycin and clindamycin, but low resistance to penicillin, ampicillin and ceftriaxone. Reduced hemoglobin and albumin, elevated C-reactive protein and procalcitonin were the common hematological changes in patients with SMG bloodstream infections. In SMG bacteremia,S.gordonii,S.sanguinisandS.orals/mitiswere the leading group causing infective endocarditis. Patients with myocardial disease factor were more likely to cause infective endocarditis byS.gordoniiandS.sanguinis, compared withS.orals/mitis.S.oralis/mitisbacteremia more occurred in patients with renal transplants progressing to pulmonary infection. Conclusion In this area, β-lactam antibiotics are the best choice for treating SMG. SMG species with closely related phylogenetically show different prevalence and risk of clinical disease in bloodstream infection patients. Early prevention and diagnosis of bacteremia caused by SMG are necessary for clinical diagnosis, treatment and effective control of infectious diseases progression.

OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

Objective:Using oral iron preparations as the positive control,this study explores the efficacy and safety of intravenous iron isomaltoside in the treatment of moderate postpartum iron deficiency anemia(IDA),as well as the impact of anemia correction on fatigue levels and psychological status among postpartum patients.Methods:Eighty-four patients with moderate iron deficiency anemia during puerperium who were delivered at the Tianjin Medical University General Hospital from April 1,2022,to June 30,2023,were included and randomly as-signed1∶1 to the intravenous group(37cases)or the oraliron group(39cases).Theintravenous group received a one-time infusion of ferric derisomaltose(1000 mg)within 1-3 days after delivery.In the oral group,oral iron(150 mg/day for at least 4 weeks)was administered from postpartum day 1.The improvement effect of anemia and the occurrence of adverse reactions were compared between groups.At the same time,the quality of life assess-ment[Multidimensional Fatigue Inventory(MFI)]and postpartum depression assessment[Edinburgh Postnatal Depression Scale(EPDS)]were self-evaluated by electronic questionnaire,and the degree of fatigue and psy-chological condition were compared.Results:①After treatment,6-8 weeks postpartum follow-up showed that the Hb level(129.1±6.4 g/L vs.119.4±9.6 g/L),Hb growth value(49.8±9.4 g/L vs.39.8±11.8 g/L),and Hb growth percentage(62.7%vs.49.3%)Hb increase≥40 g/L(89.2%vs.53.8%),hematocrit level(34.8%vs.29.4%),mean corpuscular volume(97.6 fl vs.92.5 fl)in the intravenous group were significantly higher than those in the control group(P<0.05).②Comparison within groups:compared with the pre-treatment,the MFI scores of the intravenous group and the oral group were significantly lower after treatment(P<0.05),while the difference between the EPDS scores of the two groups before and after treatment was not statistically significant(P>0.05).Comparison between groups:there was no statistically significant difference in MFI scores and EPDS scores between the two groups before and after treatment(P>0.05).③There were no grade 3 or above adverse events occurred in either group.Conclusions:Intravenous ferric derisomaltose is effective and safe for the treat-ment of postpartum anemia,improving hemoglobin levels more rapidly than oral iron,with similar improvements in fatigue levels and no significant impact on postpartum depression as assessed by EPDS.

Objective:By comparing the relevant image manifestations and diagnostic results of high resolution CT (HRCT) and digital radio graphy (DR), to deeply explore the clinical application value of HRCT in the diagnosis and staging of occupational pneumoconiosis.Methods:A total of 180 pneumoconiosis patients with different stages diagnosed in Guangzhou Twelfth People's Hospital from January 2022 to May 2023 were selected as the research objects by systematic sampling method, and their HRCT and DR examinations were performed. The display of lung imaging features of patients with pneumoconiosis by the two examination methods was analyzed, and the chi-square test and rank sum test were used to compare the differences in diagnostic staging results and the detection of pulmonary complications.Results:Among the patients with pneumoconiosis, there were 174 males and 6 females, with an age of (53.11±12.22) years old and a working age of (14.94±11.43) years. The number of lung areas with category 0 small opacity profusion in the HRCT images of patients was less than that in the DR images, and the number of lung areas with category 1 small opacity profusion was more than that in the DR images ( P<0.05). There was no statistically significant difference in the number of lung areas with category 2 and category 3 small opacity profusion detected by the two images ( P>0.05). The distribution of diagnostic differences between HRCT and DR images for the staging of pneumoconiosis was statistically significant ( P<0.05), and the detection rates of HRCT for pneumoconiosis complicated with pulmonary tuberculosis, pneumonia, atelectasis, lymph node tumefaction, and pleural thickening were all higher than those of DR ( P<0.05) . Conclusion:In the diagnosis of pneumoconiosis, HRCT has advantages over DR images in showing the fine structure of the lungs, determining the degree and extent of lesions. It is of great significance for discovering and differentiating complications of pneumoconiosis, and providing an important basis for clinical staging.

Objective:To analyze the clinical characteristics and cytokines expression characteristics in infants with mild and severe respiratory syncytial virus (RSV) infection.Methods:From May 2023 to December 2023, plasma samples and clinical information were collected from 16 infants with RSV infection and 14 control infants. Cytek Aurora flow cytometry (Cytek, America) and Enzyme linked immunosorbent assay (ELISA) were used to detect the expression levels of 25 cytokines after mild and severe RSV infection.Results:Cough and nasal obstruction were the main clinical manifestations in infants with mild RSV infection, accompanied by polypnea, wheezing and other symptoms. The main symptoms of severe RSV infection were cough and rales, accompanied by fever and polypnea. In comparison with the control group, the expression levels of IL-2, IL-4, IL-5, IL-6, IL-9, IL-13, IL-22, TNF-α, IFN-α, IFN-β, MIP-1β, I-TAC, ENA-78, GROα, Eotaxin, and MCP-1 in the RSV infection group all exhibited an upregulation trend. Both IP-10 and MIP-3α demonstrated a downward trend in the RSV infection group; however, there was no statistically significant difference ( P>0.05). The levels of IL-10, IFN-γ, MIP-1α, and IL-8 in the RSV infection group were significantly higher than those in the control group, whereas the levels of MIG, TARC, and RANTES in the RSV infection group were significantly lower than those in the control group ( P<0.05). The levels of IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-13, IL-22, IFN-β, IFN-γ, TNF-α, IL-8, I-TAC, MIP-1β, Eotaxin, and MCP-1 in the mild RSV infection group were significantly higher than those in the severe RSV infection group ( P>0.05). Among these, the levels of MIG, RANTES, TARC, MIP-3α, and ENA-78 in the mild infection group were all lower than those in the severe infection group. The expressions of ENA-78 and MIP-1α in the severe infection group were significantly higher than those in the mild infection group and also higher than those in the control group. There was no significant difference in IP-10 and GROα between the mild and severe RSV infection groups ( P>0.05). Conclusions:The differences in clinical features and cytokines between infants with mild and severe RSV infection provide important data support for the prevention and treatment of RSV infection in infants.
