Huangqintang, with its accurate efficacy, is a classic formula specialized in treating dysentery recommended and promoted by medical experts from successive generations, and it was included in the Catalogue of Ancient Classic Prescriptions (the Second Batch, Han Chinese medicine prescriptions) published by the National Administration of Traditional Chinses Medicine (TCM) in 2023. The method of bibliometrics was applied in this study to conduct textual research on the classic formula Huangqintang and provide a literature reference for the development of modern preparations of Huangqintang. A total of 2 026 pieces of ancient literature were searched with "Huangqintang" as the key word, and 23 pieces of effective data were selected, involving 15 ancient TCM books. The historic evolution, composition, dosage, origin, processing methods, preparation and decocting methods, efficiency, and application of Huangqintang were carefully reviewed. The results showed that Huangqintang was first recorded in the Treatise on Febrile Diseases written by ZHANG Zhongjing. It has the effect of clearing heat, stopping dysentery, regulating the middle, and downbearing counterflow and has become one of the classic formulas widely used in clinical practice. Because of its accurate efficacy, medical experts from later generations have modified it from its original composition. Though many prescriptions have different names, it is the manifestation of physicians' inheritance and development of the thought of ZHANG Zhongjing. Ancient literature showed this prescription had wide indications yet centered on digestive system diseases such as dysentery and abdominal pain. Modern applications of Huangqintang involve digestive, respiratory, ophthalmology and otolaryngology, gynecological, skin, musculoskeletal system, and connective tissue, and this prescription has great potential in treating ulcerative colitis, diarrhea, acute enteritis, and damp-heat dysentery. Through a systematic textual excavation and review of the ancient literature about Huangqintang, the paper has confirmed its key information, so as to provide a scientific basis for the clinical application and new drug development of classic formulas.

ObjectiveMicrotube associated protein-2 (MAP-2), alpha-tubulin (α-tubulin), and synaptophysin (SYP) are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein (α-Syn) and its oligomers, MAP-2, α-tubulin, and SYP of patients with liver and kidney deficiency of Parkinson's disease (PD), analyzed their correlation, and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group (30 cases) and a control group (30 cases). Both groups were treated on the basis of PD medicine, and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score, TCM syndrome score, and expression of serum α-Syn and its oligomers, MAP-2, α-tubulin, and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment, the TCM syndrome score, UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ score of the treatment group were significantly decreased (P<0.05, P<0.01). The UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment (P<0.05). After treatment, the total effective rate of the control group was 63.3% (19/30), and that of the treatment group was 86.7% (26/30). The clinical effect of the observation group was better than the control group (Z=-2.03, P<0.05). The total effective rate of the observation group was better than that of the control group, and the difference was statistically significant (χ2=5.136, P<0.05). After treatment, the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased (P<0.05, P<0.01). The levels of serum α-Syn and its oligomers, as well as α-tubulin in the treatment group, were significantly decreased compared with those in the control group after treatment (P<0.05, P<0.01). Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD (P<0.05, P<0.01) but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin (P<0.05, P<0.01) but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 (P<0.05). ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

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.

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.

This paper explored the disease mechanism of autism spectrum disorders (ASD) from the perspectives of “vital activity” and “qi configuration”, and it is believed that “vital activity” represents the internal regulatory mechanisms of the human body, while “qi configuration” represents the ability of the body to communicate and adapt to the external environment. Abnormal genetic factors lead to the extinction of vital activity in children with ASD, resulting in increased susceptibility to ASD. Environmental instability leads to the solitary qi configuration in ASD, triggering and exacerbating the manifestations of ASD on the basis of genetic susceptibility. In addition, epigenetic mechanisms also play an important role in the pathogenesis of ASD. Imbalances in vital activity and disruptions in qi configuration result in failure in qi transformation of zang-fu organs, with abnormal symptoms manifested through the five orifices. It is proposed that the treatment of ASD should aim to achieve a harmonious interaction between “vital activity” and “qi configuration” to accelerate the recovery of affected children.

ObjectiveExisting artificial vision devices can be divided into two types: implanted devices and extracorporeal devices, both of which have some disadvantages. The former requires surgical implantation, which may lead to irreversible trauma, while the latter has some defects such as relatively simple instructions, limited application scenarios and relying too much on the judgment of artificial intelligence (AI) to provide enough security. Here we propose a system that has voice interaction and can convert surrounding environment information into tactile commands on head and neck. Compared with existing extracorporeal devices, our device can provide a larger capacity of information and has advantages such as lower cost, lower risk, suitable for a variety of life and work scenarios. MethodsWith the latest remote wireless communication and chip technologies, microelectronic devices, cameras and sensors worn by the user, as well as the huge database and computing power in the cloud, the backend staff can get a full insight into the scenario, environmental parameters and status of the user remotely (for example, across the city) in real time. In the meanwhile, by comparing the cloud database and in-memory database and with the help of AI-assisted recognition and manual analysis, they can quickly develop the most reasonable action plan and send instructions to the user. In addition, the backend staff can provide humanistic care and emotional sustenance through voice dialogs. ResultsThis study originally proposes the concept of “remote virtual companion” and demonstrates the related hardware and software as well as test results. The system can not only achieve basic guide functions, for example, helping a person with visual impairment to shop in supermarkets, find seats at cafes, walk on the streets, construct complex puzzles, and play cards, but also can meet the demand for fast-paced daily tasks such as cycling. ConclusionExperimental results show that this “remote virtual companion” is applicable for various scenarios and demands. It can help blind people with their travels, shopping and entertainment, or accompany the elderlies with their trips, wilderness explorations, and travels.
