Huopo Xialingtang is a famous classical formula for treating dampness and warmth， which is included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. In this paper， bibliometric methods was used to collect the literature related to Huopo Xialingtang， and 16 items of related literature were retrieved， involving five medical books， which were used to textual research on the origin， name， composition， drug dosage， preparation method， processing and main treatment symptoms of this formula. The results indicated that Huopo Xialingtang was originated from Yiyuan written by Shi Funan in the Qing dynasty， and and was later named and extended by He Lianchen. The composition of the proposed formula was consistent with the record of Yiyuan， and the origin of each Chinese materia medica was basically clear. Houpo was the dried bark and root bark of Magnolia officinalis， Zexie was the dried tubers of Alisma orientale， Kuxingren was the dried mature seeds of Prunus armeniaca， Doukou was the dried mature fruits of Amomum kravanh， the origin of Tuhuoxiang was consistent with the 2018 edition of Shanghai Standards of Processing Chinese Crud Drugs， and the origins of the remaining Chinese medicines were consistent with the 2020 edition of Chinese Pharmacopoeia. The converted dose of each Chinese medicine was 7.46 g for Agastache rugosa， 3.73 g for Magnoliae Officinalis Cortex， 8.39 g for Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine， 11.19 g for Poria， 11.19 g for Armeniacae Semen Amarum， 14.92 g for Coicis Semen， 2.61 g for Amomi Fructus Rotundus， 5.60 g for Polyporus， 5.60 g for Alismatis Rhizoma， 14.92 g for Tetrapanacis Medulla. Huopo Xialingtang was initially used for the treatment of dampness and warmth at the beginning of the disease， and was later expanded to treat dampness obstruction， dampness-warming dysentery and so on， but always with the dampness-heat in the lungs and spleen as the pathogenesis. In modern times， the clinical application is more extensive， used in digestive， respiratory， endocrine， nervous system and other types of diseases， especially for chronic gastritis， stomach pain and fever. By combing the ancient literature of Huopo Xialingtang， we verified the origin of the formula and determined the key information of the prescription， which can provide literature reference for the clinical application and drug development of this formula.

Objective:To develop a quality assessment index system for infection prevention and control in integrated medical and elderly care facilities, providing methods for assessing infection control quality and a theoretical basis for enhancing infection prevention and control capabilities.Methods:This study initially constructed a framework for the quality evaluation index system through literature reviews, work specifications and standards and expert interviews. The Delphi method was employed to conduct two rounds of consultations with 19 experts to evaluate the necessity, feasibility, stability, and sensitivity of the indicators. The expert′s active coefficient, authority coefficient, degree of consensus, and coordination were statistically analyzed. The indicators were revised based on expert opinions to finalize the evaluation index system. The weights of the evaluation dimensions were determined using the Analytic Hierarchy Process (AHP), while the weights of the indicators were determined using the proportional allocation method. Reliability was assessed via Cronbach′s α coefficient, and content validity was verified through the Content Validity Index ( CVI). Results:After two rounds of expert consultation, the expert positive coefficient, expert authority coefficient ( Cr) and expert coordination coefficient Kendall′s W was 100%, 0.992 and 0.634 ( P<0.001), indicating high expert authority, good concentration and coordination of opinions. The assessment index system for infection prevention and control quality in integrated medical and elderly care facilities was ultimately constructed, comprising three primary indicators, 18 secondary indicators and 68 tertiary indicators. Among the primary indicators, the process quality had the highest weight of 0.338. Within the process quality, the secondary indicators with the highest weights were infection control material allocation, hand hygiene quality and the management of cluster outbreaks. A total of 11 unique evaluation indicators for integrated medical and elderly care facilities were established, with the highest weighted indicator being the rate of standardized surveillance of infection-related risk factors. Reliability and validity analyses demonstrated that the overall Cronbach′s α coefficient of the system was 0.991, and the Scale-level Content Validity Index was 0.936, confirming good reliability and validity. Conclusion:The evaluation index system constructed in this study can serve as an effective assessment tool for the quantitative evaluation of infection control quality in integrated medical and elderly care facilities. Furthermore, it is recommended that the system undergo continuous optimization concerning its application.

Objective To construct a model combining with traditional Chinese medicine(TCM)syndrome for predicting the risk of disease progression in patients with idiopathic membranous nephropathy(IMN)by machine learning methods,thus to quantitatively evaluating the value of TCM syndrome in the prediction of the risk of disease progression in IMN.Methods Monofactor analysis,recursive feature elimination(RFE)and multivariate binary Logistic regression analysis were used to screen the independent related factors affecting the risk of disease progression of IMN,and then a risk prediction model was constructed.A total of 102 patients with IMN were randomly assigned to the training set and the test set in a ratio of 65∶35,and then the comparison was conducted in the performance indicators of accuracy,sensitivity,specificity,F1 value,and area under the receiver operating characteristic(ROC)area under the curve(AUC)of the risk prediction model with or without the inclusion of the TCM syndrome information.Results Before the inclusion of TCM syndrome information,12 clinical characteristic variables for patients with MN were obtained after monofactor analysis combined with RFE screening,and they were age,hemoglobin quantification,urinary occult blood,24-hour urine protein quantification,urine protein-creatinine ratio,estimated glomerular filtration rate(eGFR),creatinine,uric acid,alanine transaminase,anti-phospholipase A2 receptor antibody(PLA2R-Ab),total cholesterol,and low-density lipoprotein cholesterd.A risk cholesterol prediction model containing the above variables was constructed.The multivariate binary Logistic regression analysis showed that the differences of the clinical variables mentioned above between the training-set group and test-set group were statistically significant,and the risk prediction model presented good sensitivity and predictability.Monofactor analysis combined with RFE screening was performed again after the inclusion of TCM syndrome information,and then 14 variables were obtained,which included blood stasis syndrome and dampness obstruction syndrome.The sensitivity and specificity of the model with the inclusion of the TCM syndrome information were significantly improved when compared with those without the inclusion of TCM syndrome information.Conclusion The results of the study initially indicate that TCM syndrome can be used as an important supplementary variable for predicting the risk of disease progression in IMN,and will provide a reference for intelligent diagnosis through the integration of traditional Chinese and western medicine information,and will supply the guidance for the treatment of IMN with TCM.

Objective To explore serum periostein,interleukin (IL)-5,IL-8 and IL-13 expression levels in patients with allergic bronchopulmonary aspergillosis (ABPA) and their correlation with lung function. Methods 73 patients with ABPA admitted to Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 2019 to December 2022 were selected as the case group,and 60 asthma patients during the same period were selected as the control group. ELISA was used to detect serum levels of Periodin,IL-5,IL-8 and IL-13. Pearson analysis was used to investigate the correlation between serum Periodin and lung function indicators. Multivariate Logistic regression analysis was used to investigate the effect of serum period on the occurrence of ABPA in patients with bronchial asthma,and the diagnostic value of serum Periodin for ABPA was evaluated by ROC curves. Results Compared with the control group,the serum levels of Periostin(97.64±28.05 ng/ml vs 57.39±22.78 ng/ml),IL-5(1.62±0.35 ng/L vs 0.59±0.31 ng/L),IL-8(79.22±10.26 ng/L vs 51.04±8.26 ng/L )and IL-13(1.59±0.43 ng/L vs 1.02±0.51 ng/L)in the case group increased(t=6.997～17.776),the total serum IgE,specific IgE positivity rate,eosinophil count and fractional exhaled nitric oxide (FeNO) levels in the case group increased(t=9.341～131.469),the percentage of forced expiratory volume in the first second to the expected value (FEV1％pred),and forced expiratory volume in the first second/forced vital capacity (FEV1/FVC) levels decreased(t=2.652,3.126),the differences were statistically significant(all P<0.05),respectively. Serum Periodin in ABPA patients was positively correlated with IL-5,IL-8,IL-13 and FeNO (r=0.539～0.695,all P<0.05),and negatively correlated with FEV1％ pred,FVC％ pred and FEV1/FVC (r=-0.657,-0.506,-0.582,all P<0.05). Compared with serum Periosin>68.35 ng/ml,bronchial asthma patients with serum Periodin 97.83～131.02 ng/ml and>131.02 ng/ml had a higher risk of ABPA,and the differences were statistically significant (all P<0.05),respectively .The area under the curve of combined diagnosis of ABPA with serum Periodin+IL-5+IL-8+IL-13+total IgE+specific IgE+eosinophils was better than that of single periodin and periodin combined with inflammatory factor diagnosis,the difference was statistically significant(Z=3.562,2.931,all P<0.05).Conclusion Serum Periostin is abnormally elevated in ABPA patients,which is closely related to lung function. Early detection can assist in clinical diagnosis of ABPA.

Objective To investigate the effect of dihydroartemisinin(DHA)for enhancing the inhibitory effect of cisplatin(DDP)on DDP-resistant nasopharyngeal carcinoma cell line HNE1/DDP and explore the mechanism.Methods CCK-8 method was used to assess the survival rate of HNE1/DDP cells treated with DHA(0,5,10,20,40,80,and 160 μmol/L)and DDP(0,4,8,16,32,64,128 μmol/L)for 24 or 48 h,and the combination index of DHA and DDP was calculated using Compusyn software.HNE1/DDP cells treated with DHA,DDP,or their combination for 24 h were examined for cell viability,proliferation and colony formation ability using CCK-8,EdU and colony-forming assays.Flow cytometry was used to detect cell apoptosis and intracellular reactive oxygen species(ROS).The expression levels of apoptosis-related proteins cleaved PARP,cleaved caspase-9 and cleaved caspase-3 were detected by Western blotting.The effects of N-acetyl-cysteine(a ROS inhibitor)on proliferation and apoptosis of HNE1/DDP cells with combined treatment with DHA and DDP were analyzed.Results Different concentrations of DHA and DDP alone both significantly inhibited the viability of HNE1/DDP cells.The combination index of DHA(5 μmol/L)combined with DDP(8,16,32,64,128 μmol/L)were all below 1.Compared with DHA or DDP alone,their combined treatment more potently decreased the cell viability,colony-forming ability and the number of EdU-positive cells,and significantly increased the apoptotic rate,intracellular ROS level,and the expression levels of cleaved PARP,cleaved caspase-9 and cleaved caspase-3 in HNE1/DDP cells.N-acetyl-cysteine pretreatment obviously attenuated the inhibitory effect on proliferation and apoptosis-inducing effect of DHA combined with DDP in HNE1/DDP cells(P<0.01).Conclusion DHA enhances the growth-inhibitory and apoptosis-inducing effect of DDP on HNE1/DDP cells possibly by promoting accumulation of intracellular ROS.

【Objective】 To explore the effectiveness of using donor plasma reinfusion to flush the leukoreduction system (LRS) chamber during the final reinfusion phase with the Trima Accel automated blood collection system in preventing the reduction of CD4+ and CD8+ T lymphocytes. 【Methods】 A longitudinal and cross-sectional study was designed. CD4+ count<200 cells/μL and CD8+ count<125 cells/μL were considered as the criteria for deficiency. Eighteen first-time platelet donors were followed up. The lymphocyte count was measured at 0, 3-6 and 7-14 times of blood donation in the last 300 days. 170 healthy blood donors who have not donated blood were selected as the control group. According to the cut-off point(October 2021), 88 blood donors who mainly used automatic blood collection system to donate platelet apheresis in the last 365 days(median blood donation times ≥17.5)were divided into three groups(A, B and C)and blood samples were obtained. The time for Groups A, B and C started donating platelet apheresis were as follows: Group A: before October 2019, Group B: from October 2019 to September 2021, Group C: after October 2021. Blood samples were analyzed to obtain blood counts including CD4 + and CD8 + T lymphocytes. Blood samples were analyzed to obtain blood cell counts including CD4+ and CD8+ T lymphocytes. Through a comparative analysis, this study aimed to determine if there are any statistical differences in the detection indices between the follow-up groups with varying frequencies of blood donation, the control group, and groups A, B, and C. This approach was employed to infer the efficacy of donor plasma reinfusion in flushing the leukoreduction system (LRS) chamber for preventing the decline of CD4+ and CD8+ T lymphocytes. 【Results】 Eighteen first-time blood donors who were converted to regular platelet apheresis donors did not show a decrease of CD4 + and CD8 + T lymphocytes in the 5 th and 11 th blood donation (median number of blood donation), and there was no significant difference between the above indexes and those in the 0 th blood donation. Among the previous frequent blood donors, the CD4+ and CD8+ T lymphocyte counts in Group B and Group C are both higher than the standard value, showing no statistical difference from the control group. Among regular blood donors, the CD4+ and CD8+ T lymphocyte counts in groups B and C were higher than the criteria values, and had no statistical difference compared to the control group.The CD4+ T lymphocyte count in Group A was normal, with only one donor in Group A having a CD8+ T lymphocyte count below 125 cells/μL. This donor has donated 281 times of platelet apheresis, and the group he belongs to has started blood donation 2-21 years(median of 5 years) before the adjustment of reinfusion mode. The CD4+ and CD8+ T lymphocyte counts in Group A showed significant differences compared to the control group, with median counts (Group A/Control Group) of 359/521 and 257/372, respectively, P<0.001. In Group A, 0%(0/35) had a CD4+ count below 200 cells/μL, and 2.85%(1/35) of donors had a CD8+ count below 125 cells/μL, which was far lower than the proportion of CD4+ and CD8+ T cell deficiency found in regular apheresis donors by John M. Gansner and Mahboubeh Rahmani. The study showed that the adjustment of the plasma reinfusion mode did not further reduce the T lymphocyte counts in blood donors, but instead further restored the T lymphocyte counts in regular blood donors. This indicated that after the adjustment of plasma reinfusion mode, blood donors might not have lost CD4+ and CD8+ T lymphocytes during blood donation, or only lost a small amount, and can recover even if they donate platelet apheresis frequently. 【Conclusion】 Trima Accel automated blood collection system has a good effect on preventing CD4 + and CD8 + T lymphocytes from being reduced by flushing the LRS chamber with donor plasma.
