Objective To explore the feasibility of magnetic compression technique (MCR) in the treatment of severe single mid-ureteral stricture in a rabbit model. Methods After 10 female New Zealand rabbits were selected, the distal end of the right ureter was ligated with silk thread. Two weeks after the operation, when the right ureter was dilated, the mid-ureter was ligated again with silk thread to create a severe single mid-ureteral stricture animal model. Longitudinal incisions were made at the upper and lower ends of the ligation site, and cylindrical NdFeB magnets with central holes (sub-magnets and main magnets) were placed to anastomose and recanalize the mid-ureteral stricture. The magnets were adjusted to the appropriate position to automatically align and attract each other. The longitudinal incision sites of the ureter were sutured with 6-0 Prolene thread, and the abdominal cavity was closed layer by layer. The operation time was recorded. X-ray films were taken every two days to confirm the position of the magnets and record the time of magnet detachment. Three weeks after the operation, the anastomotic specimens were obtained, and the formation of the anastomosis was evaluated with gross observation and histological staining. Results Two weeks after ligation, all experimental rabbits showed obvious dilation of the right ureter. The mid-ureteral ligation and placement of the male and female magnets were successfully completed in all 10 experimental rabbits, with an operation time of (24.00±5.15)minutes. The male and female magnets attracted each other well. X-ray examination showed that the magnets detached and entered the distal ureter (14.0±1.9) days after magnetic compression. The recanalization of the severe single mid-ureteral stricture was successfully achieved. The gross specimens and histological examination of the anastomosis showed that the anastomosis remained patent and the mucosal healing was good. All experimental rabbits survived well after the operation without serious complications. Conclusion MCT provides a new idea and novel method for the treatment of mid-ureteral stricture. This study confirmed the feasibility of this technique in treating severe single mid-ureteral stricture in a rabbit model. The operation is relatively simple and has potential for clinical application.

Yuejuwan is a classic formula widely used by doctors to relieve liver and depression, with precise clinical efficacy in traditional Chinese medicine (TCM). The authors used bibliometric methods to collect and collate 495 ancient data related to Yuejuwan, and 105 valid data were screened out, involving 68 ancient Chinese medical books. After systematic verification of the origin of the formula of Yuejuwan, the main treatment symptoms, the principle of the formula, the composition of the drug, the dosage, the preparation method, the decoction method, and other information, the results showed that Yuejuwan originated from the Danxi Xinfa (《丹溪心法》) of the Yuan Dynasty by ZHU Zhenheng, and it is composed of five medicines, namely Atractylodis Rhizoma, Cyperi Rhizom, Chuanxiong Rhizoma, Massa Medicata Fermentata, and Gardeniae Fructus. In terms of drug base, Atractylodis Rhizoma, Cyperi Rhizom, Chuanxiong Rhizoma, and Gardeniae Fructus are in line with the records in the 2020 edition of Chinese Pharmacopoeia, and Massa Medicata Fermentata is used. The preparation method is as follows: Massa Medicata Fermentata and Gardeniae Fructus are fried, and Cyperi Rhizoma is roasted in vinegar. Chuanxiong Rhizoma is used in the raw form, and Atractylodis Rhizoma is prepared with rice swill. The formula can regulate Qi and relieve depression and broaden the middle and remove fullness. It is clinically used for the treatment of six types of depression syndromes, chest and diaphragm plumpness, abdominal distension and leg acid, acid swallowing and vomiting, eating and drinking disharmony, toothache, mouth and tongue sores, and other diseases. The most used dosage of the formula in the ancient records through the ages is converted into the modern dosage, namely 3.05 g Atractylodis Rhizoma, 3.05 g Cyperi Rhizoma, 3.05 g Chuanxiong Rhizoma, 3.05 g Massa Medicata Fermentata, and 3.05 g Gardeniae Fructus, and the daily dosage is 15.25 g. The converted dosage is similar to that recorded in the 2020 edition of the Chinese Pharmacopoeia. The formula is in pill form, and medicine should be taken with lukewarm boiled water after the meal. Through the excavation of the ancient literature related to Yuejuwan, the key information of the formula is identified, with a view to providing a more accurate reference for the clinical application of Yuejuwan and subsequent in-depth investigation.

Gualou Niubangtang is a classic formula for eliminating swelling and dispersing lumps, commonly used in the clinical treatment of breast diseases in traditional Chinese medicine (TCM). This paper employed bibliometric methods to collect and organize 12 pieces of data from ancient texts related to Gualou Niubangtang, ultimately screening 10 valid references from 10 ancient Chinese medical books. Information regarding the prescription origin, main indications, formulation principles, drug composition, dosages, preparation methods, and decoction techniques was systematically verified. The results indicate that Gualou Niubangtang originates from the Orthodox Manual of External Medicine (Wai Ke Zheng Zong) by Chen Shigong in the Ming Dynasty. The formula consists of 12 Chinese medicines, including Citri Reticulatae Pericarpium, Arctii Fructus, Gardeniae Fructus, Lonicerae Japonicae Flos, Glycyrrhizae Radix et Rhizoma, Trichosanthis Semen, Scutellariae Radix, Trichosanthis Radix, Forsythiae Fructus, Gleditsiae Spina, Bupleuri Radix, and Citri Reticulatae Pericarpium Viridm. In terms of drug origins, the dominant radical for Trichosanthis Semen and Trichosanthis Radix is Trichosanthes kirilowii, and the historical dominant radical for Glycyrrhizae Radix et Rhizoma is Glycyrrhiza uralensis. The nine medicines, Citri Reticulatae Pericarpium, Arctii Fructus, Gardeniae Fructus, Lonicerae Japonicae Flos, Scutellariae Radix, Forsythiae Fructus, Gleditsiae Spina, Bupleuri Radix, and Citri Reticulatae Pericarpium Viridm, are consistent with the 2020 edition of the Chinese Pharmacopoeia. The preparation methods involve frying Arctii Fructus, removing the heart from Forsythiae Fructus, while the remaining 10 medicines are used raw. The efficacy includes clearing heat, removing toxins, reducing swelling, and dispersing lumps. Clinically, it is used to treat conditions such as breast carbuncles, breast gangrene, and knot-like swellings and pain. The dosage, converted to modern standards, includes 3.73 g of Trichosanthis Semen, 3.73 g of Trichosanthis Radix, 3.73 g of Arctii Fructus, 3.73 g of Scutellariae Radix, 3.73 g of Gardeniae Fructus, 3.73 g of Forsythiae Fructus, 3.73 g of Gleditsiae Spina, 3.73 g of Lonicerae Japonicae Flos, 3.73 g of Glycyrrhizae Radix et Rhizoma, 3.73 g of Citri Reticulatae Pericarpium, 1.85 g of Citri Reticulatae Pericarpium Viridm, and 1.85 g of Bupleuri Radix. The preparation is in the form of a decoction, with the 12 medicines added to 400 mL of water and decocted until 160 mL. The liquid is then mixed with 200 mL of yellow wine and taken before meals three times a day. Through the excavation and organization of ancient literature regarding Gualou Niubangtang, key information has been identified to provide a scientific basis for its clinical application and further development.

Platelet elevation is a rare manifestation in the peripheral blood of patients with chronic myeloid leukemia (CML). In this paper, we report for the first time a case of CML combined with cerebral hemorrhage manifested by abnormally elevated platelets. The patient had elevated platelets in the peripheral blood, showed normal coagulation function, and underwent intracranial hematoma removal due to cerebral hemorrhage. After the operation, bleeding from the operated area and other systems occurred, and the patient was diagnosed as having accelerated CML after combining bone marrow biopsy and genetic testing. His condition was controlled after administration of flumatinib through a jejunal tube. Based on this patient's experience, the feasibility ofadministering flumatinib via a jejunostomy tube was determined, which is the first report of its kind in China and abroad.This article summarizes the diagnosis and treatment process of this patient, with the aim of providing a warning and reference for clinicians.

Objective:To analyze and explore the common radiomics features of radiation pneumonitis (RP) in patients with lung cancer and esophageal cancer, and then establish a prediction model that can predict the occurrence of RP in two types of cancer after radiotherapy.Methods:Clinical data of 100 patients with stage Ⅲ lung cancer and 100 patients with stage Ⅲ esophageal cancer who received radical radiotherapy were retrospectively analyzed. The RP was graded by imaging data and clinical information during follow-up, and the planning CT images were collected. The whole lung was used as the volume of interest to extract radiomics features. The radiomics features, clinical and dosimetric parameters related to RP were analyzed, and the model was constructed by machine learning.Results:A total of 1691 radiomics features were extracted from CT images. After ANOVA and LASSO dimensionality reduction in lung cancer and esophageal cancer patients, 8 and 6 radiomics features associated with RP were identified, and 5 of them were the same. Using the random forest to construct the prediction model, lung cancer and esophageal cancer were alternately used as the training and validation sets. The AUC values of esophageal cancer and lung cancer as the independent validation set were 0.662 and 0.645.Conclusions:It is feasible to construct a common prediction model of RP in patients with lung cancer and esophageal cancer. Nevertheless, it is necessary to further expand the sample size and include clinical and dosimetric parameters to increase its accuracy, stability and generalization ability.
