The classic formula Fangji Fulingtang is from ZHANG Zhongjing's Synopsis of the Golden Chamber in the Eastern Han dynasty. It is composed of Stephaniae Tetrandrae Radix, Astragali Radix, Cinnamomi Ramulus, Poria, and Glycyrrhizae Radix et Rhizoma, with the effects of reinforcing Qi and invigorating spleen, warming Yang and promoting urination. By a review of ancient medical books, this paper summarizes the composition, original plants, processing, dosage, decocting methods, indications and other key information of Fangji Fulingtang, aiming to provide a literature basis for the research, development, and clinical application of preparations based on this formula. Synonyms of Fangji Fulingtang exist in ancient medical books, while the formula composition in the Synopsis of the Golden Chamber is more widespread and far-reaching. In this formula, Stephaniae Tetrandrae Radix, Astragali Radix, Cinnamomi Ramulus, Poria, and Glycyrrhizae Radix et Rhizoma are the dried root of Stephania tetrandra, the dried root of Astragalus embranaceus var. mongholicus, the dried shoot of Cinnamomum cassia, the dried sclerotium of Poria cocos, and the dried root and rhizome of Glycyrrhiza uralensis, respectively. Fangji Fulingtang is mainly produced into powder, with the dosage and decocting method used in the past dynasties basically following the original formula. Each bag is composed of Stephaniae Tetrandrae Radix 13.80 g, Astragali Radix 13.80 g, Cinnamomi Ramulus 13.80 g, Poria 27.60 g, and Glycyrrhizae Radix et Rhizoma 9.20 g. The raw materials are purified, decocted in water from 1 200 mL to 400 mL, and the decoction should be taken warm, 3 times a day. Fangji Fulingtang was originally designed for treating skin edema, and then it was used to treat impediment in the Qing dynasty. In modern times, it is mostly used to treat musculoskeletal and connective tissue diseases and circulatory system diseases, demonstrating definite effects on various types of edema and heart failure. This paper clarifies the inheritance of Fangji Fulingtang and reveals its key information (attached to the end of this paper), aiming to provide a theoretical basis for the development of preparations based on this formula.

BACKGROUND:Cervical disc herniation can cause pain in the neck and shoulder area,as well as radiating pain in the upper limbs.The incidence rate is increasing year by year and tends to affect younger individuals.Fully understanding the biomechanical characteristics of the cervical spine in adolescents is of great significance for preventing and delaying the onset of cervical disc herniation in this age group. OBJECTIVE:To reconstruct cervical spine models for both healthy adolescents and adolescent patients with cervical disc herniation utilizing finite element analysis techniques,to analyze the motion range of the C1-T1 cervical vertebrae as well as the biomechanical characteristics of the annulus fibrosus,nucleus pulposus,endplates,and the cartilage of the small joints. METHODS:A normal adolescent's cervical spine and an adolescent patient with cervical disc herniation were selected in this study.The continuous scan cervical spine CT raw image data were imported into Mimics 21.0 in DICOM format.The C1-T1 vertebrae were reconstructed separately.Subsequently,the established models were imported into the 3-Matic software for disc reconstruction.The perfected models were then imported into Hypermesh software for meshing of the vertebrae,nucleus pulposus,annulus fibrosus,and ligaments,creating valid geometric models.After assigning material properties,the final models were imported into ABAQUS software to observe the joint motion range of the C1-C7 cervical vertebrae segments under different conditions,and to analyze the biomechanical characteristics of the annulus fibrosus,nucleus pulposus,endplates,and small joint cartilage of each cervical spine segment. RESULTS AND CONCLUSION:(1)In six different conditions,the joint motion range of the C1 vertebra in the cervical spine models of both normal adolescent and adolescent patient with cervical disc herniation was higher than that of the other vertebrae.Additionally,the joint motion range of each cervical spine segment in normal adolescent was greater than that in adolescent patient with cervical disc herniation.(2)In the cervical spine model of normal adolescent,the maximum stress values in the annulus fibrosus and nucleus pulposus were found on the left side during C2-3 flexion conditions(0.43 MPa and 0.17 MPa,respectively).In the cervical spine model of adolescent patient with cervical disc herniation,the maximum stress values were found on the left side during C7-T1 flexion conditions(0.54 MPa and 0.18 MPa,respectively).(3)In the cervical spine model of normal adolescent,the maximum stress value on the endplate was found on the left side of the upper endplate of C3 during flexion conditions(1.46 MPa).In the model of adolescent patient with cervical disc herniation,the maximum stress value on the endplate was found on the left side of the lower endplate of C7 during flexion conditions(1.32 MPa).(4)In the cervical spine model of normal adolescent,the maximum stress value in the small joint cartilage was found in the C2-3 left rotation conditions(0.98 MPa).In adolescent patient with cervical disc herniation,the stress in the small joint cartilage significantly increased under different conditions,especially in C1-2,with the maximum stress found during left flexion(3.50 MPa).(5)It is concluded that compared to normal adolescent,adolescent patient with cervical disc herniation exhibits altered cervical curvature and a decrease in overall joint motion range in the cervical spine.In adolescent with cervical disc herniation,there is a significant increase in stress on the annulus fibrosus,nucleus pulposus,and endplates in the C7-T1 segment.The stress on the left articular cartilage of the C1-2 is notable.Abnormal cervical curvature may be the primary factor causing these stress changes.

ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan, excavate and analyze the key information of Xieqingwan, and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition, dosage, decocting methods, usage, and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows: Angelicae Sinensis Radix, Gentianae Radix et Rhizoma, Chuanxiong Rhizoma, Gardenia seeds, Radix et Rhizoma Rhei, Notopterygii Rhizoma et Radix, and Saposhnikoviae Radix were grounded to fine powder, decocted with honey, and finally formed into pills with the size of a chicken head (1.5 g). It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology, neurology, dermatology, digestion, and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity, removing fire and relaxing the bowels, and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan, which is often modified and used in treating Tourette syndrome, herpes, febrile convulsion, sleepwalking, and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan, induces its historic evolution, and confirms its key information, so as to provide a reference for the future development of Xieqingwan.

ObjectiveTo investigate the awareness and clinical practice of guidelines for the prevention and treatment of chronic hepatitis B (2022 edition) among clinicians. MethodsFrom July 19 to December 31, 2024, a self-designed electronic questionnaire was distributed via the WeChat mini program to collect related data from 1 588 clinicians nationwide, including their awareness and practice based on 18 questions regarding testing and referral, diagnosis and treatment, and follow-up. ResultsAmong all respondents, only 350 clinicians correctly understood all the updated key points of antiviral indications and treatment for special populations in the 2022 edition of guidelines for the prevention and treatment of chronic hepatitis B, with an overall awareness rate of 22.0%. Only 20% — 40% of the patients with positive HBV DNA and an age of >30 years receive antiviral therapy, while 80% — 100% of the patients with positive HBV DNA and a family history of hepatitis B cirrhosis or hepatocellular carcinoma receive antiviral therapy. The median follow-up rates at 1 year, 3 years, and 5 years were 67.5% 57.5% and 47.5%,respectively, showing a trend of gradual reduction, which might be associated with the influencing factors such as insufficient time for follow-up management by clinicians, insufficient awareness of the disease among patients, and poor adherence to follow-up. ConclusionThere is a gap between the awareness and practice of guidelines for the prevention and treatment of chronic hepatitis B (2022 edition) among clinicians. It is recommended to further strengthen training and focus on the whole process of “detection, diagnosis, treatment, and management” for patients with chronic hepatitis B in healthcare institutions, in order to promote the implementation of the guidelines.

Houpo Sanwutang, included in the Catalogue of Ancient Classical Prescriptions (Second Batch), was first recorded in the Synopsis of Golden Chamber written by ZHANG Zhongjing from the Eastern Han dynasty and was modified by successive generations of medical experts. A total of 37 pieces of effective data involving 37 ancient Chinese medical books were retrieved from different databases. Through literature mining, statistical analysis, and data processing, combined with modern articles, this study employed bibliometrics to investigate the historical origin, composition, decoction methods, clinical application, and other key information. The results showed that the medicinal origin of Houpo Sanwutang was clearly documented in classic books. Based on the conversion of the measurements from the Han Dynasty, it is recommended that 110.4 g Magnolia Officinalis Cortex, 55.2 g Rhei Radix et Rhizoma, and 72 g Aurantii Fructus Immaturus should be taken. Magnolia Officinalis Cortex and Aurantii Fructus Immaturus should be decocted with 2 400 mL water first, and 1 000 mL should be taken from the decocted liquid. Following this, Rhei Radix et Rhizoma should be added for further decoction, and then 600 mL should be taken from the decocted liquid. A single dose of administration is 200 mL, and the medication can be stopped when patients restore smooth bowel movement. Houpo Sanwutang has the effect of moving Qi, relieving stuffiness and fullness, removing food stagnation, and regulating bowels. It can be used in treating abdominal distending pain, guarding, constipation, and other diseases with the pathogenesis of stagnated heat and stagnated Qi in the stomach. The above results provide reference for the future development and research of Houpo Sanwutang.

ObjectiveTo explore the effect of modified Lianpoyin formula (LPYJWF) in the treatment of Helicobacter pylori (Hp)-associated gastric mucosal damage based on mitochondrial autophagy and NLRP3 inflammasome signaling pathway. MethodsA total of 60 eight-week-old Balb/c male mice were assigned via the random number table method into control, model, high-dose LPYJWF (LPYJWF-H, 27.3 g·kg-1·d-1), medium-dose LPYJWF (LPYJWF-M, 13.65 g·kg-1·d-1), low-dose LPYJWF (LPYJWF-L, 6.83 g·kg-1·d-1), and quadruple therapy groups. Except the control group, other groups were modeled for Hp infection. Mice were administrated with LPYJWF at corresponding doses by gavage. Quadruple therapy group was given omeprazole (6.06 mg·kg-1·d-1) + amoxicillin (303 mg·kg-1·d-1) + clarithromycin (151.67 mg·kg-1·d-1) + colloidal pectin capsules (30.3 mg·kg-1·d-1) by gavage. The control group was given an equal volume of 0.9% NaCl for 14 days. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of gastric mucosa, and Warthin-Starry (W-S) silver staining was used to detect Hp colonization. Transmission electron microscopy was employed to observe the mitochondrial ultrastructure of the gastric tissue, and immunofluorescence co-localization assay was adopted to detect the expression of mitochondrial transcription factor A (TFAM) and translocase of the outer mitochondrial membrane member 20 (TOMM20). The water-soluble tetrazolium salt method and thiobarbituric acid method were used to determine the levels of superoxide dismutase (SOD) and malondialdehyde (MDA), respectively, in the gastric tissue. Western blot was employed to measure the protein levels of PTEN-induced kinase 1 (PINK1), Parkin, p62, microtubule-associated protein 1 light chain 3 (LC3), NOD-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), interleukin-1β (IL-1β), and interleukin-18 (IL-18). Real-time quantitative PCR was employed to assess the mRNA levels of PINK1, Parkin, p62, and LC3. ResultsCompared with the control group, the model group presented obvious gastric mucosal damage, colonization of a large number of Hp, severe mitochondrial damage, vacuolated structures due to excessive autophagy, reduced TOMM20 and TFAM co-expression in the gastric mucosal tissue, and reduced SOD and increased MDA (P<0.01). In addition, the gastric tissue in the model group showed up-regulated protein and mRNA levels of PINK1, Parkin, and LC3 and down-regulated protein and mRNA levels of p62 (P<0.01, as well as increased expression of inflammasome-associated proteins NLRP3, ASC, IL-1β, and IL-18 (P<0.01). Compared with the model group, the LPYJWF and quadruple therapy groups showed alleviated pathological damage of gastric mucosa, reduced Hp colonization, mitigated mitochondrial damage, and increased co-expression of TOMM20 and TFAM. The SOD level was elevated in the LPYJWF-L group (P<0.01), and the MDA levels became lowered in the LPYJWF and quadruple therapy groups (P<0.05, P<0.01). Furthermore, the LPYJWF and quadruple therapy groups showed down-regulated mRNA levels of PINK1, Parkin, and LC3 and protein levels of PINK1 and Parkin, and up-regulated mRNA level of p62 (P<0.01). The LPYJWF-M, LPYJWF-H, and quadruple therapy groups showcased down-regulated LC3 Ⅱ/LC3 Ⅰ level (P<0.05, P<0.01) and up-regulated protein level of p62 (P<0.01). The expression of inflammasome-associated proteins NLRP3, ASC, IL-1β, and IL-18 were reduced in the LPYJWF and quadruple therapy groups (P<0.05, P<0.01). ConclusionLPYJWF ameliorates gastric mucosal damage and exerts mucosa-protective effects in Hp-infected mice, which may be related to the inhibition of excessive mitochondrial autophagy, thereby inhibiting the activation of the NLRP3 inflammasome pathway.
