This article systematically analyzes the historical evolution of the name， origin， medicinal parts， processing and other aspects of Euphorbiae Pekinensis Radix（EPR） by referring to the herbal medicine， medical books， prescription books and other documents of the past dynasties， combined with the relevant modern research materials， so as to provide a basis for the development and utilization of famous classical formulas containing this herbal medicine. According to research， EPR was first recorded in the Shennong Bencaojing in the name of Daji， and it is the correct name of the herbal medicine in all dynasties， there are also other aliases such as Qiongju， Hongya Daji， and Xiamaxian. The dried roots of Euphorbia pekinensis from Euphorbiaceae was the mainstream of the past dynasties. Before the Ming dynasty， the above ground parts of E. pekinensis were used as Zeqi in herbal works. However， since LI Shizhen in the Ming dynasty proposed that the origin of Zeqi should be E. helioscopia， the aerial part of EPR is no longer used as medicine. Since modern times， the roots of Knoxia valerianoides has been used as EPR， and has become the mainstream of commodities， which should be corrected. Throughout history， it has been recorded that the main producing areas were Jiangsu， Anhui， Zhejiang， Shanxi and other regions， while modern botanical survey have shown that EPR is a widespread species distributed throughout the country. In ancient times， the harvesting time of EPR was mostly the twelfth lunar month， while in modern time， it is more common to harvest in autumn and winter. The main processing methods of EPR in ancient times were vinegar processing， wine processing， and stir frying， while in modern times， it is uniformly vinegar processing. In the medicinal properties and clinical aspects， the records are basically consistent throughout history， mainly characterized by bitter taste， cold and toxic nature. Its main efficacy is expelling water retention and reducing swelling. Based on the textual research， it is suggested to choose the dried roots of E. pekinensis when famous classical formulas containing EPR， processing method can be based on the original specified prescription requirements， if the processing method is not clear， it is recommended to use vinegar-processed products as medicine.

Objective To investigate the factors associated with unplanned readmission within 30 days after discharge in adult patients who underwent coronary artery bypass grafting (CABG) and to develop and validate a risk prediction model. Methods A retrospective analysis was conducted on the clinical data of patients who underwent isolated CABG at the Nanjing First Hospital between January 2020 and June 2024. Data from January 2020 to August 2023 were used as a training set, and data from September 2023 to June 2024 were used as a validation set. In the training set, patients were divided into a readmission group and a non-readmission group based on whether they had unplanned readmission within 30 days post-discharge. Clinical data between the two groups were compared, and logistic regression was performed to identify independent risk factors for unplanned readmission. A risk prediction model and a nomogram were constructed, and internal validation was performed to assess the model’s performance. The validation set was used for validation. Results A total of 2 460 patients were included, comprising 1 787 males and 673 females, with a median age of 70 (34, 89) years. The training set included 1 932 patients, and the validation set included 528 patients. In the training set, there were statistically significant differences between the readmission group (79 patients) and the non-readmission group (1 853 patients) in terms of gender, age, carotid artery stenosis, history of myocardial infarction, preoperative anemia, and heart failure classification (P<0.05). The main causes of readmission were poor wound healing, postoperative pulmonary infections, and new-onset atrial fibrillation. Multivariable logistic regression analysis revealed that females [OR=1.659, 95%CI (1.022, 2.692), P=0.041], age [OR=1.042, 95%CI (1.011, 1.075), P=0.008], carotid artery stenosis [OR=1.680, 95%CI (1.130, 2.496), P=0.010], duration of first ICU stay [OR=1.359, 95%CI (1.195, 1.545), P<0.001], and the second ICU admission [OR=4.142, 95%CI (1.507, 11.383), P=0.006] were independent risk factors for unplanned readmission. In the internal validation, the area under the curve (AUC) was 0.806, and the net benefit rate of the clinical decision curve analysis (DCA) was >3%. In the validation set, the AUC was 0.732, and the DCA net benefit rate ranged from 3% to 48%. Conclusion Females, age, carotid artery stenosis, duration of first ICU stay, and second ICU admission are independent risk factors for unplanned readmission within 30 days after isolated CABG. The constructed nomogram demonstrates good predictive power.

ObjectiveTo investigate the effect of Xuanfei Zhisou prescription on the interleukin-17 （IL-17） signaling pathway in model rats with chronic obstructive pulmonary disease （COPD）. MethodA total of 60 Wistar rats were randomly divided into a blank group （10 rats） and a model group （50 rats）， and COPD model rats were established by tracheal infusion of lipopolysaccharide combined with passive fumigation. After modeling， the rats were divided into the model group， dexamethasone group， and high， medium， and low-dose Xuanfei Zhisou prescription groups （3.6， 1.8， 0.9 g·kg^-1·d^-1） according to the random number table. Rats in the blank group and model group were given normal saline of 10 mL·kg^-1·d^-1 by gavage administration， and the intervention groups of Xuanfei Zhisou prescription were given corresponding drugs. Rats in the dexamethasone group were given dexamethasone of 2.57×10^-4 g·kg^-1·d^-1 for 28 days. The level of pulmonary function indexes in rats was measured by a pulmonary function detector. The contents of interleukin-6 （IL-6）， interleukin-8 （IL-8）， IL-17， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） were detected by enzyme-linked immunosorbent assay （ELISA）. The positive expressions of IL-17A， IL-17RA， nuclear factor-κB activator 1 （Act1）， tumor necrosis factor-associated factor 6 （TRAF6）， p-p38 mitogen-activated protein kinase （p-p38 MAPK）， nuclear factor-κB p65 （NF-κB p65）， and phosphorylation were detected by immunohistochemistry （IHC）. The protein expression levels of IL-17A， IL-17RA， Act1， and TRAF6 in the lung tissue were detected by Western blot. The mRNA expressions of IL-17A， IL-17RA， Act1， and TRAF6 in the lung tissue were detected by Real-time polymerase chain reaction （Real-time PCR）. ResultCompared with the blank group， the serum contents of IL-6， IL-8， IL-17， IL-1β， and TNF-α in the model group were significantly increased （P<0.05）， and the flow rate and volume indexes of pulmonary function in the model group were significantly decreased （P<0.05）， while the time indexes and other indexes were significantly increased （P<0.05）. The mRNA and protein expression levels of IL-17A， IL-17RA， Act1， and TRAF6 in pulmonary tissue and the positive expressions of downstream NF-κB p65， p-NF-κB p65， and p-p38 MAPK were increased （P<0.05）. Compared with the model group， the levels of IL-6， IL-8， IL-17， IL-1β， and TNF-α in the serum of all treatment groups were decreased to varying degrees （P<0.05）， and the indexes of pulmonary function were improved to different degrees （P<0.05）. The mRNA and protein levels of IL-17A， IL-17RA， Act1， and TRAF6 and the positive expression of downstream NF-κB p65， p-NF-κB p65， and p-p38 MAPK in high and medium-dose Xuanfei Zhisou prescription groups were significantly decreased （P<0.05）. ConclusionXuanfei Zhisou prescription can effectively resist inflammation of COPD rats. The mechanism may be related to down-regulating the protein expression of IL-17A， IL-17RA， Act1， and TRAF6， inhibiting downstream NF-κB and p38 MAPK signaling pathways， and reducing the release of IL-6， IL-8， TNF-α， IL-17， and IL-1β， thus reducing the airway inflammation response.

ObjectiveTo observe the effect of earthworm protein on the expression of phosphatidylinositol 3-kinase/protein kinase B/nuclear factor E₂-related factor 2 （PI3K/Akt/Nrf2） pathway in the aorta of spontaneously hypertensive rats （SHR） and explore mechanism of earthworm protein in treating hypertensive vascular endothelial dysfunction （VED）. MethodTen 10-week-old Wistar Kyoto （WKY） rats and fifty SHR rats were selected for a week of adaptive feeding. WKY rats were selected as the normal group， and fifty SHR rats were randomized according to body weight into model， valsartan （8×10^-3 g·kg^-1·d^-1）， and high-， medium-， and low-dose （0.2， 0.1， 0.05 g·kg^-1·d^-1， respectively） earthworm protein groups. The normal and model groups were administrated with equal volume of double distilled water by gavage. During the drug intervention period， the general situations of rats in each group were observed and their blood pressure was monitored at specific time points every other week before and after administration. After 8 weeks of drug intervention， enzyme-linked immunosorbent assay was employed to measure the levels of angiotensin-Ⅱ （Ang-Ⅱ） and endothelin-1 （ET-1） in the serum of rats in each group. The corresponding kits were used to determine the levels of nitric oxide （NO）， malondialdehyde （MDA）， glutathione peroxidase （GPX）， superoxide dismutase （SOD）， and ferrous ion （Fe²⁺）. Hematoxylin-eosin （HE） staining was employed to observe the changes in the intima of the aorta. Fluorescence quantitative polymerase chain reaction （Real-time PCR） was employed to measure the mRNA levels of PI3K， Akt， Nrf2， heme oxygenase-1 （HO-1）， and glutathione peroxidase 4 （GPX4） in the aortic tissue. Western blotting was used to determine the protein levels of p-PI3K （Tyr467/199）， PI3K， p-Akt （Ser473）， Akt， Nrf2， HO-1， and GPX4 in the thoracic aorta. ResultCompared with the normal group， the model group had decreased body mass， increased irritability， severe endothelial damage， elevated blood pressure and serum levels of Ang-Ⅱ， ET1， MDA， and Fe²⁺ （P<0.01）， lowered NO level （P<0.01）， and down-regulated mRNA and protein levels of p-PI3K （Tyr467/199）， PI3K， p-Akt （Ser473）， Akt， Nrf2， HO-1， and GPX4 in the aortic tissue （P<0.01）. Compared with the model group， drug intervention caused no significant change in the body mass， calmed the rats， alleviated the endothelial damage， lowered blood pressure and serum levels of Ang-Ⅱ， ET1， MDA， and Fe²⁺ （P<0.01）， elevated the NO level （P<0.05）， and up-regulated the mRNA and protein levels of p-PI3K （Tyr467/199）， PI3K， p-Akt （Ser473）， Akt， Nrf2， HO-1， and GPX4 （P<0.05）. ConclusionThe earthworm protein can exert antihypertensive effects by ameliorating VED in SHR. Specifically， it may regulate the PI3K/Akt/Nrf2 signaling pathway to inhibit oxidative stress and ferroptosis.

By reviewing ancient materia medica， prescription books， medical books and modern literature， this article makes a systematic textual research on the name， origin， commercial specification， producing area， harvesting and processing of Scutellariae Radix used in famous classical formulas according to the historical development， in order to provide a reference for the development and utilization of famous classical formulas. Scutellariae Radix was first named as Qian， Qin and so on， while Huangqin was used as the official name in ancient literature， as well as many aliases such as Fuchang， Huangwen and Dufu. The main origin of Scutellariae Radix in the past dynasties was Scutellaria baicalensis， and other Scutellaria plants were also used for Scutellariae Radix at different times. The medicinal parts of Scutellariae Radix in all dynasties are roots， since the Northern and Southern dynasties， it has gradually differentiated into Ziqin and Kuqin with different efficacy according to their different growth stages and characteristics， and continued to this day. At present， most of Scutellariae Radix are Ziqin in the market， due to the influence of cultivation cost， index component content requirements and other factors. The production area of Scutellariae Radix recorded in ancient literature was wide and gradually expanded from the Yangtze River basin to the northward. Since modern times， Chengde city of Hebei province has been respected as a geo-authentic area， now S. baicalensis is cultivated in a wide area， spreading over north and northeast China. Scutellariae Radix was mostly used as raw products in the early period， and a variety of processed products appeared in the Ming dynasty. Development continues to this day， Scutellariae Radix mainly includes raw products and wine-processed products. According to the research conclusion， it is suggested that S. baicalensis should be used as Scutellariae Radix in famous classical formulas， and the selection of its commercial specifications and processed products can be comprehensively determined according to the requirements of original prescription and the clinical effect.

By consulting ancient materia medica， medical books， prescription books and modern literature， this paper systematically combed and reviewed the name， origin， scientific name evolution， producting area， quality evaluation， medicinal parts， harvesting and processing and traditional efficacy of Lasiosphaera Calvatia. The results show that Mabo was first recorded in Mingyi Bielu. Since then， all dynasties have taken Mabo as a legitimate name. Before the Song dynasty， only Calvatia lilacina was used as the original plant of Lasiosphaera Calvatia， which was expanded after the Song dynasty with the appearance of C. gigantea， Lasiosphaera fenzlii， Bovistella radicata and other varieties. Until modern times， there was an addition of Lycoperdon perlatum， L. pyriforme and other original plants of Lasiosphaera Calvatia. Since 1975， the original plant of Lasiosphaera Calvatia in various regulations and academic monographs has been basically uniform for C. lilacina， Lasiosphaera fenzlii and C. gigantea. Resource of the medicinal fungus was widely distributed in China and was mainly wild. From ancient times to the present， the medicinal parts of Lasiosphaera Calvatia are all fruiting body， which is harvested in summer and autumn， and its processing method was to take powder in ancient times， but to cut blocks in modern times. In recent times， its quality has been summarized as large， thin-skinned， intact， full， loose-bubbled and elastic. The medicinal efficacy has been developed from very good for all scores， and after the Ming and Qing dynasties， it is consistent with the 2020 edition of Chinese Pharmacopoeia， with the efficacy of clearing the lung， promoting pharynx， relieving fever and hemostasis， mainly treating cough aphonia， throat obstruction and pharyngeal pain， vomiting blood， epistaxis， hemoptysis， and external treating sores and bleeding from cuts and wounds. Based on the results of herbal textual research， it is suggested that C. lilacina is the first choice for the origin of Lasiosphaera Calvatia involved in famous classical formulas， and it is processed into block or powder for medicine.

OBJECTIVE: To compare clinical effects of the improved interface screw fixation of femoral end of anterior cruciate ligament with classic femoral lateral loop plate fixation. METHODS: A retrospective analysis of 65 patients who underwent arthroscopic anterior cruciate ligament reconstruction from January 2019 to September 2021 were performed. According to the different fixation methods of the femoral side, 35 patients were divided into loop plate fixation(loop plate group), including 27 males and 8 females, aged from 18 to 50 years old with an average of (35.00±7.60) years old;30 patients in interface screw fixation(interface screw group), including 20 males and 10 females, aged from 18 to 50 years old with an average of (32.00±8.50) years old. Hospital stay, hospital expenses, operation time, complications, C-reactive protein at 1, 3, 6 days after operation, and postoperative Lysholm score and International Knee Documentation Committee(IKDC) score at 18 months were compared between two groups. RESULTS: All patients were successfully operated, and obtained follow-up from 18 to 36 months with an average of (25.16±4.50) months. Anterior drawer test and Lachman test of all patients turned to negative. There were no statistical differences in hospital stay, hospital expenses and complications between two groups(P>0.05);operation time in loop plate group was (74.00±6.84) min, and (91.67±6.34) min in interface screw group, and had difference between two groups(P<0.05). C-reactive protein on the 1st and 3rd day after operation was (40.00±10.10), (20.00±8.23) mg·L^-1 in loop plate group, and (60.00±8.93), (30.00±8.66) mg·L^-1 in interface nail group, had statistical difference between two groups (P<0.05);while there was no difference in C-reactive protein on the 6th day after operation(P>0.05). At 18 months after operation, Lysholm and IKDC scores showed no significant difference between two groups (P>0.05). In loop plate group, medullary enlargement on coronal and sagittal views were (2.75±0.19) mm, (1.55±0.25) mm, and (2.81±0.22) mm, (1.61±0.20) mm in interface screw group, and had statistical difference between two groups(P<0.05). CONCLUSION In the reconstruction of anterior cruciate ligament, the common interface screw on the femoral side is changed to the sheath interface screw, and intramedullary screw is changed to the compression and fixation of tendon from outside to inside of joint. Although the operation procedure is relatively complicated and operation time is slightly longer, it has advantages of no residual metal foreign body after operation, and clinical effect is no different from classical loop plate suspension fixation, which is still a good choice.

OBJECTIVE: To explore the therapeutic effect of multiple small diameter drilling combined with extracorporeal shock wave therapy (ESWT) under C-arm X-raylocalization in patients with early osteonecrosis of the femoral head (ONFH). METHODS: A total of 106 cases of early ONFH patients admitted from May 2015 to May 2017 were retrospectively selected as the study subjects. According to different treatment methods, the patients were divided into observation group and control group, 53 cases in each group. The observation group was treated with multiple small-diameter drilling combined with ESWT under C-arm positioning in the observation group, including 41 males and 12 females with an age of (45.85±6.01) years old (22 to 70 years old);and the control group was treated with ESWT, including 34 males and 19 females with an age of (45.12±5.83) years old(20 to 68 years old) in the control group. The modified Harris hip scores(mHHS), visual analog scale(VAS), hip flexion range, hip abduction and adduction range, ONFH area ratio and clinical efficacy were compared between twe groups before and after treatment. Kaplan-Meier method was used to draw a survival curve to compare the femoral head survival rate between two groups during the 3-year follow-up period after treatment. RESULTS: There were no complications such as poor wound healing and infection. All of 106 patients were followed up for 28 to 36 months with an average of (31.06±4.28) months. MHHS score, hip flexion range and hip abduction and adduction range in the observation group were increased from (63.85±5.42) scores, (23.79±2.21) °, (32.40±4.19) ° before treatment to (85.51±5.69) scores, (34.65±2.73)°, (43.32±5.71)° at 2 years after treatment, respectively(P<0.05). The above indicators in the control group increased from (64.73±5.64)°, (23.82±2.18)°, (32.45±4.13)° before treatment to (81.65±5.48) scores, (32.79±2.87)°, (39.75±5.68)°at two years after treatment, respectively(P<0.05). VAS score and ONFH area ratio in the observation group decreased from (5.76±1.41) scores and (35.07±4.96)% before treatment to (3.39±1.02) scores and (22.04±3.23)% at 2 years after treatment, respectively(P<0.05). The above indicatiors in control group decreased from (5.73±1.45) scores and (35.24±5.18)% before treatment to (4.43±1.21) scores and (28.32±3.76)% at 2 years after treatment, respectively(P<0.05), and the improvement in the observation group was significantly higher than that in the control group(P<0.05). At 3 years after treatment, the femoral head survival rate in the observation group was higher than that in the control group (P<0.05). CONCLUSION Multiple small diameter drilling combined with ESWT under C-arm positioning can significantly improve the clinical symptoms of patients with early ONFH, relieve pain and improve clinical efficacy.

Objective     To investigate the clinical characteristics, risk factors and perioperative outcome of prolonged mechanical ventilation (PMV) in elderly patients undergoing coronary artery bypass grafting (CABG). Methods     The data of elderly patients receiving CABG in the Nanjing First Hospital from January 2013 to June 2019 were collected. All patients were divided into a control group and a PMV group according to whether ventilation time≥24 h. The clinical characteristics and risk factors of PMV were compared between the two groups. Variables were 1∶1 balanced through propensity score matching (PSM) and perioperative outcomes of two groups was analyzed. Results     Finally 956 patients were collected, including 187 in the PMV group and 769 in the control group. There were 586 males and 370 females aged 70-94 (74.3±3.5) years. Compared with the control group, the PMV group had higher rates of smoking,  preoperative renal impairment, intraoperative blood transfusion and intra-aortic balloon pump (IABP) implantation, worse cardiac function, lower glomerular filtration rate and ejection fraction, larger left atrial diameter, longer cardiopulmonary bypass time and aortic cross-clamping time (P<0.05). There was no statistical difference in other clinical data between the two groups (P>0.05). Binary multivariate logistic regression analysis showed that females, smoking, chronic obstructive pulmonary disease, left ventricular ejection fraction≤56.0%, cardiopulmonary bypass time>106.0 min, IABP implantation and intraoperative blood transfusion were independent risk factors for PMV in elderly patients. After PSM, there were 146 patients in the control group and the PMV group, respectively. The PMV group had longer ICU stay and length of hospital stay and more drainage volume compared with the control group (all P<0.05). There was no statistical difference in perioperative mortality or other complications between the two groups (all P>0.05). Conclusion    There are a lot of factors associated with PMV of the elderly patients undergoing on-pump CABG. In order to establish a complete and formal PMV prediction model, clinicians can make a further step of assessment according to perioperative elements, and improve the prognosis of such patients.

【Objective】 To investigate the resource allocation status of blood testing laboratories in 14 blood stations in Gansu Province, explore the impact of differences in basic conditions on the comprehensive testing ability of laboratories, so as to promote the homogenization and standardization of blood screening capacity in blood stations in Gansu and improve blood safety and effectivenes. 【Methods】 An evaluation index system of laboratory resource allocation was constructed and a question-naire was designed. The data of human resources, infrastructure and key equipment of 14 blood stations were collected. The entropy weight -TOPSIS method was used to evaluate and rank the resource allocation of 14 blood stations. 【Results】 In the comprehensive evaluation of blood testing laboratory resource allocation in 14 blood stations in Gansu, the top three were laboratories A, B and I, and the last three were laboratories G, M and J. On the whole, the main issue was unreasonable structure of human resources: most laboratories had unreasonable age structure; except for Laboratory A, there was no personnel with bachelor's degree or above in laboratories; most laboratories had not established a team with intermediate professional titles. In terms of infrastructure, the size of seven laboratories could not meet the needs of modern laboratory testing, and all eight blood stations had no spare nucleic acid laboratories nor a mutual spare laboratory with other blood stations As for the key equipment, 5 laboratories had no automatic blood grouping diagnostic instrument, 5 laboratories only had one set of enzyme immunoassay detection system, 3 laboratories had no spare equipment for the key equipment, which means if the equipment failure could not be repaired in time, the release of results would be affected. 【Conclusion】 There were significant differences in human resources, infrastructure and key equipment of blood testing laboratories in 14 blood stations in Gansu, which had a great impact on laboratory testing capacity and subsequent development. It is suggested that governments at all levels and health administrative departments optimize the input of laboratory resource allocation according to the blood collection volume of blood stations to gradually narrow the differences in resource distribution between different regions, improve the degree of laboratory automation and optimize the personnel structure, so as to build high-quality and efficient blood testing laboratories and ensure the safety of clinical blood use.
