The purpose of this paper is to explore the decoction and dosing methods of rhubarb root and rhizome in classical prescriptions and to provide a reference basis for the clinical use of rhubarb root and rhizome. By collating the relevant classical prescriptions of rhubarb root and rhizome in Shanghan Lun and Jingui Yaolüe, the relationship between its decoction and dosing methods and the syndrome was analyzed. The decoction of rhubarb root and rhizome in classical prescriptions can be divided into three categories: simultaneous decoction, decoction later, and other methods (impregnation in Mafei decoction, decoction with water from the well spring first taken in the morning, and pills). If it enters the blood level or wants to slow down, rhubarb root and rhizome should be decocted at the same time with other drugs. If it enters the qi level and wants to speed up, rhubarb root and rhizome should be decocted later. If it wants to upwardly move, rhubarb root and rhizome should be immersed in Mafei decoction. If it wants to suppress liver yang, rhubarb root and rhizome should be decocted with water from the well spring first taken in the morning. If the disease is prolonged, rhubarb root and rhizome should be taken in pill form. The dosing methods of rhubarb root and rhizome can be divided into five categories: draught, twice, three times, before meals, and unspecified. For acute and serious illnesses with excess of pathogenic qi and adequate vital qi, we choose draught. For gastrointestinal diseases, we choose to take the medicine twice. For achieving a moderate and long-lasting effect, we choose to take the medicine three times. If the disease is located in the lower part of the heart and abdomen, we choose to take it before meals. The use of rhubarb root and rhizome in clinical practice requires the selection of the appropriate decoction and dosing methods according to the location of the disease, the severity of the disease, the patient′s constitution, and the condition after taking the medicine.

" Lijie and yellowish sweating" originates from the chapter on stroke and arthralgia diseases in Synopsis of Golden Chamber. Later generations typically interpret it as yellow fluid oozing from painful joints, a characteristic manifestation of arthralgia. In Western medicine, Lijie corresponds to diseases such as gouty arthritis, with its primary clinical manifestations being redness, swelling, heat, and painful joints, most often without yellow fluid discharge. Therefore, the interpretation of " Lijie and yellowish sweating" contradicts the clinical manifestations often observed in this disease. Thus, this article reinterprets the meaning of " Lijie and yellowish sweating" from the pathogenesis of " sweat exposure to water, as if water harms the heart" , combined with the viewpoints of other medical practitioners. Determining the meaning of " yellowish sweating" is crucial for understanding the pathogenesis of arthralgia and clarifying the relationship between arthralgia and yellowish sweating. ZHANG Zhongjing mentioned arthralgia and " yellowish sweating" together, not to differentiate between the two diseases but to emphasize the common pathogenesis of the two, namely, the cold and dampness injuring the heart, blood, and vessels. This paper proposes a new explanation of " Lijie and yellowish sweating" , which suggests that " yellowish sweating" is not confined to the joints but can be found all over the body. The pathogenesis of " Lijie and yellowish sweating" lies in the insufficiency of the liver and kidney and exogenous water dampness, leading to disharmony between nutrient qi and defensive qi and between yin and yang. Primary treatment should harmonize yingfen and weifen, as well as tonify and replenish the liver and kidney. The clinical selection of medicines can be considered Guizhi Decotion, a type of formula. The pathogenesis of " Lijie and yellowish sweating" is complex, and clinical treatment should be comprehensively considered to achieve the best therapeutic effect.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

This article summarized the experience of national TCM master Wang Qingguo in treating liver cirrhosis with triplet herbs.Professor Wang believes that the etiology and pathogenesis of liver cirrhosis are always based on the disorders of liver,spleen and kidney function,the dampness and heat retention is an important factor of the disease.When the disease enters the collaterals,blood stasis runs through the development of the disease,qi,blood and water are both pathological products and pathogenic factors.Therefore,supporting the healthy qi and eliminating pathogens,and treating both manifestation and root cause of disease are important treatment principles for liver cirrhosis.Professor Wang takes the whole as the main principle and selects triplet herbs that are suitable for the pathogenesis at different stages of disease development.He emphasizes the three methods of soothing the liver and promoting dampness,removing blood stasis and diuresis,and supporting the healthy qi and eliminating pathogens.He flexibly applies the treatment,and the clinical efficacy is remarkable.

Objective:To investigate the clinical value of multiparametric myocardial imaging using a dual-layer detector spectral CT in the non-invasive preoperative assessment of patients with coronary atherosclerotic heart disease (CHD) undergoing percutaneous coronary intervention (PCI).Methods:The clinical and imaging data of 90 patients who underwent coronary CT angiography (CCTA) with dual-layer spectral detector CT and invasive coronary angiography (ICA) within 30 days at the Affiliated Changshu Hospital of Nantong University from January 2021 to October 2022 were retrospectively analyzed. A total of 189 coronary arteries were included in the study cohort. The patients were divided into PCI ( n=44) and non-PCI groups ( n=46) according to whether they received PCI after evaluation with ICA. The diameter stenosis rate of the coronary arteries, myocardial iodine concentration (IC) and effective atomic number (Z eff) values were obtained from CCTA conventional and spectral images. The IC values and Z eff values of the myocardium in the areas with abnormal perfusion were compared with those in the areas with normal perfusion. The diagnostic performance of these parameters, as well as their combined model, was evaluated and compared using receiver operating characteristic (ROC) curve and area under the curve (AUC) in the pre-PCI assessment of patients with CHD. Results:Baseline patient data did not show statistically significant differences between the PCI and non-PCI groups (all P>0.05). There were statistically significant differences in IC values [(0.42±0.28) and (2.26±0.48) mg/ml] and Z eff values (7.39±0.33 and 8.50±0.25) between the myocardium areas with abnormal perfusion and the myocardium areas with normal perfusion in all patients (all P<0.001). The AUC for assessing whether patients with CHD need PCI treatment using myocardial IC and Z eff values were 0.865 and 0.853, respectively, which were significantly higher than assessment based only on lumen diameter stenosis rate (AUC=0.726, P<0.001). Conclusions:The IC and Z eff derived from myocardial spectral images can be used to diagnose myocardial perfusion abnormalities in patients with CHD. The spectral myocardial multi-parameters imaging shows promising potentials in pre-PCI assessment of patients with CHD, which can improve the efficiency of evaluation and may help to avoid unnecessarily invasive procedures.

Objective:To investigate mechanisms of IL-17D on cytotoxic function of CD93+CTL in lung tumor microenviron-ment(TME)and promotion of Platycodon grandiflorum(PG).Methods:Lung of B16 melanoma model mice and control mice were treated with PG or IL-17D,and lung tumor clone formation was observed.IL-17D expression change in lung was detected by single cell sequencing,immunofluorescence staining and flow cytometry.Single cell sequencing and flow cytometry were used to detect CD93+CTL content,cytotoxic phenotype and functional factors changes,including CD107a,perforin,granzyme B,chemokine CCL2,CXCL9 and their ligand CCR2 and CXCR3.Western blot and RT-PCR were used to detect effect of Platycodonopsis saponin D on IL-17D and its transcriptional regulator NRF2 expressions in EL4 cells.Results:Pulmonary CD93+CTL highly expressed cytotoxic effectors such as perforin and CD107a and chemokine receptors CXCR3 and CCR2 than CD93-CTL,while there was no significant difference in secretion of granzyme B.In mouse lung tumor model,pulmonary IL-17D and CD93+CTL were significantly decreased(P<0.001);in tumor-bearing mice after IL-17D backfill assay,or after 10 days of treatment with PG,proportion and absolute number of IL-17D and CD93+CTL in lungs were significantly increased(P<0.05),and tumor clones were significantly reduced;meanwhile,tumor-local expressions of cytokines CCL2,CXCL9,which are related to recruitment and function of CD93+CTL,and IL-17D were significantly upregulated.Up-regulation of IL-17D and its transcriptional regulator NRF2 by PG was verified in vitro experiments on EL4 cell line by PD.Conclusion:Traditional Chinese medicine PG and its extracts can up-regulate expression of IL-17D in lungs,improve infiltration and cytotoxic function of CD93+CTL and antagonize malignant progression of lung tumors,this is an important phar-macological mechanism of PG in improving immune TME of tumors in lung.

Objective:To assess the efficacy of modified arthroscopic lower trapezius transfer with autologous hamstring tendon bridging for irreparable massive posterosuperior rotator cuff tears.Methods:A retrospective analysis was conducted on 59 patients (11 males and 48 females; mean age 66.70±6.10 years, range 55-79 years) treated between June 2019 and November 2022 for posterior superior irreparable massive rotator cuff tears. The treatment involved total arthroscopic oblique muscle transposition combined with partial rotator cuff repair. Shoulder mobility was measured in active supination, forward flexion, posterior external rotation, and abduction external rotation before surgery and at the final follow-up. The Constant-Murley shoulder function score, visual analogue scale (VAS) for pain, and American Shoulder and Elbow Surgeons (ASES) scores were assessed preoperatively, at 3 months, 6 months postoperatively, and at the final follow-up. MR examinations were conducted preoperatively and at 3, 6, and 12 months postoperatively to evaluate rotator cuff healing and retear rates.Results:All surgeries were successfully completed using an average of 3.2±0.5 anchor nails (range 3-5) per case. The mean follow-up period was 15.9±5.7 months (range 12-37 months). Significant improvements in shoulder mobility were observed postoperatively compared to preoperative measurements. The mean body external rotation angle increased from 12.0°±19.4° preoperatively to 35.3°±19.6° at the final follow-up ( P<0.05), and the mean abduction external rotation angle increased from 33.4°±22.4° to 43.4°±23.1° ( P<0.05). The mean preoperative abduction angle improved from 121.7°±47.9° to 136.4°±40.6° ( P<0.05), and the mean forward flexion supination angle improved from 117.6°±45.8° to 139.5°±33.7° ( P<0.05). Postoperative VAS scores significantly improved from 4.8±1.8 preoperatively to 0.3±0.8 at the final follow-up ( F=104.868, P<0.001). The ASES scores improved from 42.0±14.9 preoperatively to 71.7±14.6 at the final follow-up ( F=47.287, P<0.001). The Constant-Murley scores increased from 54.3±17.1 preoperatively to 76.4±13.0 at the final follow-up ( F=44.082, P<0.001). Postoperative complications included 2 complete tears and 7 partial tears (re-tear rate 15.3%). No serious complications such as shoulder joint infection, joint stiffness, or vascular nerve injury were observed. One patient developed a localized subcutaneous hematoma at the tendon extraction site, and another developed deep vein thrombosis of the lower extremity, which improved with symptomatic anticoagulation. Conclusion:Modified arthroscopic lower trapezius transfer with autologous hamstring tendon bridging effectively reduces shoulder pain, improves shoulder joint activity and function scores, and is associated with a low rate of surgical complications for patients with irreparable massive posterosuperior rotator cuff tears.

Objective:To analyze the prognostic outcomes of 1 147 patients who underwent liver transplantation at Qingdao University Affiliated Hospital and to summarize measures to enhance the efficacy of liver transplantation.Methods:A retrospective analysis was conducted on the clinical and follow-up data of 1 147 liver transplant patients at Qingdao University Affiliated Hospital.Results:The overall postoperative 1-, 3-, and 5-year survival rates for the 1 147 liver transplant patients were 87.20%, 73.40%, and 65.60%, respectively. The survival rates for benign disease liver transplant recipients were 88.01%, 84.98%, and 81.39% at 1, 3, and 5 years post-transplant, respectively, compared to recipients transplanted for malignancies of 78.11%, 64.41%, and 60.06% (all P<0.001). Among the mid vs more recent period, patients' 1-year and 3-year postoperative survival rates were 84.20%, 70.80% vs 90.50%, 71.70%, respectively,significantly in favor of recently enrolled patients ( P=0.022). In the complex surgery group, patients' 1-, 3-, and 5-year survival rates were 82.70%, 65.50%, 56.70%, while in less complicated group, it was 89.00%, 76.50%, 69.20% ( P<0.001). The primary causes of death for benign disease recipients were multi-organ failure (4.1%), while in recipients with malignant disease primary cause of death was tumor recurrence (23.7%). Postoperative complications included primary graft dysfunction, delayed graft function recovery, portal vein thrombosis, hepatic artery thrombosis, biliary stricture, post-transplant lymphoproliferative disorder, and graft-versus-host disease, with occurrence rates of 1.05%, 6.89%, 1.92%, 0.44%, 2.00%, 0.61%, and 0.44%, respectively. Conclusions:With the continuous improvement in surgical techniques and perioperative care levels, the 3-year survival rate of recipients at our center has increased. Malignant diseases and complex liver transplantation remain crucial factors affecting recipient prognosis, highlighting the need to further enhance comprehensive treatment capabilities for patients with malignant diseases and complex surgeries.

Objective:To investigate the efficacy and safety of selective dorsal rhizotomy with small incision under electrophysiological monitoring in lower limb spasticity.Methods:Twenty patients with lower limb spasticity due to craniocerebral injury admitted to Department of Neurosurgery,Tianjin Huanhu Hospital from January 2019 to December 2023 were selected. Target muscles (Ashworth Scale graded 1 + or higher) were identified preoperatively. Intraoperatively, the lower L 1 spinous process and the upper L 2 spinous process were resected to expose the cauda equina nerves. A bipolar stimulator was applied to electrically stimulate the cauda equina nerves root by root to identify the sensory nerves of the target muscles; subsequently, strings of electrical stimulation were given, 50% cauda equina nerves were cut off if no contraction of the contralateral muscles was seen, and 75% were cut off if contraction of the contralateral muscles was noted. Motor function and muscle tension were assessed and compared before and 6 months after surgery by Gross Motor Function Measure (GMFM)-66, Gross Motor Function Classification System (GMFCS), and Ashworth spasticity scale. Complications early after surgery and 6 months after surgery were observed. Results:The most common targeted muscles in these 20 patients included the gastrocnemius (the medial and lateral side, n=20), followed by the biceps femoris ( n=12) and the adductor muscles of thigh ( n=9). Number of nerves intraoperatively cut in patients with GMFCS grading 1-4 was 5.40±1.84, 9.50±6.36, 11.67±5.86, and 14.00±5.66, respectively, with significant differences ( F=5.506 , P=0.009). Grading of Ashworth spasticity scale of the target muscles before surgery in these 20 patients showed significant difference compared with that at 6 months after surgery ( P<0.05), and average rank indicated that Ashworth spasticity scale of target muscles 6 months after surgery was graded obviouly better than that before surgery. In addition, the GMFM-66 total scores and major joint motion scores of the patients 6 months after surgery were significantly higher than those before surgery ( P<0.05). Fifteen patients had fever early after surgery, 18 patients had incisional pain, and 1 patient developed reversible hypesthesia of the lower extremities; these symptoms disappeared 0.5-4.0 years after surgery. No patients developed lower limb hypokinesia, urinary and defecation disorders, or spinal deformities. Conclusion:Selective dorsal rhizotomy with small incision under electrophysiological monitoring used in this study can effectively reduce surgical trauma and relieve lower limb spasticity due to craniocerebral injury, enjoying high surgical safety.

Objective To investigate radiation doses to examinees undergoing computed tomography (CT) scanning of different body parts (the head, chest, and abdomen) in medical institutions of Shijiazhuang, China, and to provide a reference for optimizing radiation protection for examinees in medical institutions. Methods March 2021 to March 2022, eleven medical institutions of radiation monitoring in Shijiazhuang were surveyed for the basic information, scanning parameters, and dosimetric data of a total of 930 adults and children who received CT examinations. The dosimetric data of the subjects were analyzed and compared with the domestic and international diagnostic reference levels and the results of other cities in China. Results In the above hospitals, the CTDI_vol(P₅₀) of CT subjects in children's group were 17.42-50.45 mGy, 2.13-14.01 mGy and 3.58-28.20 mGy, respectively. DLP(P₅₀) ranges from 228.87 to 966.97 mGy·cm, 33.20 to 296.03 mGy·cm, and 74.90 to 926.53 mGy·cm, respectively. In the adult group, the CTDI_vol(P₅₀) in the head, chest and abdomen of CT subjects were 37.28-54.05 mGy, 6.43-14.99 mGy and 8.28-18.75 mGy, respectively. DLP(P₅₀) ranges from 372.81 to 630.56 mGy·cm, from 219.77 to 467.93 mGy·cm, and from 313.86 to 689.87 mGy·cm, respectively. The distribution of radiation doses in different-grade hospitals varied greatly. The abdomen dose of the children's hospital was higher than other hospitals. Especially the primary hospitals were significantly higher than the recommended diagnostic reference level (DRL). Conclusion In some secondary and primary hospitals, the setting of CT scanning parameters was simplified, not specific to the subjects’ age and body types. They should strictly comply with the principal of optimizing radiation protection to strengthen radiation dose optimization and supervision, reducing the radiation dose of examinees in future examinations .
