Deciphering the chemical profile and pharmacological mechanism of Jinlingzi powder against bile reflux gastritis using ultra-high performance liquid chromatography coupled with Q exactive focus mass spectrometry, network pharmacology, and molecular docking.

OBJECTIVE: To elucidate the chemical profile and the pharmacological mechanism by which Jinlingzi powder (, JLZP) treats bile reflux gastritis (BRG). METHODS: A BRG model was established in rats by oral administration of the model solution. JLZP was orally administered for 35 d. Residual gastric rate and tumor necrosis factor (TNF)-α, interleukin (IL)-6, and gastrin levels in the serum were measured, and stomach tissues were collected for histopathological analysis. We used ultra-high performance liquid chromatography coupled with Q Exactive Focus mass spectrometry to identify the chemical ingredients in JLZP. Then, protein-protein interaction and herb-compound-target networks were constructed to screen potential bioactive compounds and targets. Kyoto Encyclopedia of Genes and Genomes pathway analysis was then performed to elucidate the pathway involved in the JLZP-mediated treatment of BRG. After constructing the core compound-target-pathway interaction network, molecular docking was performed to study the binding free energy of core bioactive compounds and two candidate targets [RAC-alpha serine/threonine-protein kinase (AKT1) and phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha isoform (PIK3CA)]. RESULTS: JLZP extracts significantly promoted gastric emptying, regulating the release of cytokines (TNF-α and IL-6) and improving gastrin secretion and mucosal repair. Fifty-six compounds were tentatively characterized in JLZP. Moreover, the network pharmacology and molecular docking results showed that alkaloids and flavonoids might be the bioactive compounds in JLZP that treat BRG. JLZP might improve mucosal repair during BRG progression by modulating the phosphatidylinositol-4,5-bisphosphate 3-kinase-protein kinase B, hypoxia inducible factor-1, mitogen-activated protein kinase, forkhead box O, TNF, and IL-17 signaling pathways. CONCLUSIONS: We elucidated the chemical constituents and the pharmacological mechanism of JLZP in treating BRG and provided a basis for clinical application.

ObjectiveTo observe the effect of bilateral sequential repetitive transcranial magnetic stimulation on the motor function of upper limbs in stroke patients. MethodsFrom December, 2020 to December, 2022, 62 stroke inpatients in the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine were included. They were randomly divided into control group (n = 31) and observation group (n = 31). Both groups accepted conventional medicine and rehabilitation, as well as electroacupuncture antagonistic muscle therapy. Before electroacupuncture, the observation group acceped low-frequency repetitive transcranial magnetic stimulation at primary motor cortex (M1) on the healthy side, followed by intermittent theta burst stimulation at M1 on the affected side, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Barthel Index (MBI) and modified Ashworth Scale (MAS), and motor evoked potential (MEP) latency was compared before and after treatment. ResultsOne patient dropped down in the observation group, and no adverse event happened. After treatment, the scores of FMA-UE and MBI significantly increased (|t| > 9.953, P < 0.001), and the score of MAS and the latency of MEP significantly decreased (|t| > 5.043, P < 0.001) in both groups; while all of them were better in the observation group than in the control group (|t| > 2.237, P < 0.05). ConclusionBilateral sequential repetitive transcranial magnetic stimulation can effectively promote the recovery of upper limb motor function in stroke patients.

Traditional Chinese and Western Medicine in Treatment of Postmenopausal Osteoporosis： A Review / 中国实验方剂学杂志

Postmenopausal osteoporosis （PMOP） is a systemic disease characterized by increased bone fragility caused by insufficient estrogen secretion in women after menopause，resulting in decreased bone mass and damage to the microstructure of bone tissues. The main clinical manifestations are low back pain，osteoporotic fractures，spinal deformities，and multiple organ dysfunction. PMOP directly leads to high morbidity， high mortality， and a decline in the quality of life. In addition to miss diagnosis， it is often not treated in time. In recent years， significant progress has been made in the research on factors related to the pathogenesis of PMOP. Based on the previous findings in recent years，this article described three major pathogenesis of PMOP， including intestinal flora imbalance，oxidative stress，and abnormal differentiation of bone marrow mesenchymal stem cells （BMMSCs）， and analyzed the current status of PMOP treatment， such as syndrome differentiation and treatment，acupuncture and moxibustion，exercise therapy， and external treatment in traditional Chinese medicine （TCM）， and basic measures，drug intervention，and physical therapy in western medicine. Among them，drug intervention in western medicine treatment is generally divided into bone resorption inhibitors，bone formation promoters，and other mechanism drugs according to the mechanism of action. This article summarized the specific methods and effects or mechanisms of TCM and western medicine in the clinical treatment of PMOP，which is expected to provide a reference for formulating reasonable health management models and drug treatments in the future.

Objective:To analyze the clinical features, treatment and prognosis of asymptomatic patients with retinoblastoma.Methods:A retrospective series of case study. Eight asymptomatic patients (11 eyes) with the diagnosis of retinoblastoma by screening enrolled in Department of Ophthalmology of The Eye-ENT Hospital of Fudan University from January 2006 to March 2019 were included. There were 6 males and 3 females ranging from 2 days to 20 months, with a median age of 6 months. Five patients were unilateral retinoblastoma while 3 patients were bilateral. Based on the International Classification of Intraocular Retinoblastoma, 4 eyes were stage A, 3 eyes were stage B and 4 eyes were stage C. One patient had family history. Four patients were evaluated the Rb1 mutation. Routine ophthalmic examinations and ultra-wide field fundus imaging were performed on the 16 parents and 3 siblings of the 8 patients. Systemic intravenous chemotherapy was performed using the Carboplatin, Vincristine, Etoposide protocol, intra-arterial chemotherapy using Carboplatin and Melphalan, and local treatment involved cryotherapy and transpupillary thermotherapy. The mean follow-up time is 47.25 months.Results:None of the 8 children had any ocular symptoms. Six patients received intravenous chemotherapy (5-6 times), 1 patient received intra-arterial chemotherapy (3 times), and 1 patient just received local treatment. Among the 11 eyes, 9 eyes were treated with local cryotherapy and 8 eyes were treated with transpupillary thermotherapy. During the follow-up period, 2 patients had new tumor, and the average time was 6.3 months after the last chemotherapy. At the last follow-up, the tumor disappeared in 11 eyes, remained stable in 11 eyes. The eye protection rate was 100% (8/8) for patients without eyeball excision. The best corrected visual acuity was 0.1 for 3 eyes and 1.0 for 5 eyes. Three eyes were not found. One heterozygous mutation of Rb1 gene [1c.35_69del (p.T12fs)] was identified in 1 patient, and the other 3 patients were not detected. One had bilateral bulbar tuberculosis of the 16 parents, 1 had bilateral RB of the 3 siblings. They were the mother and brother of a child with bilateral RB.Conclusions:Fundus screening is helpful for the detection of early RB. The eye protection rate is high and the long-term vision prognosis is good after systemic or topical chemical drugs (IVC, IAC) and ocular topical treatment (cryopreservation and transpupillary thermotherapy).

[Recent advances in biosynthesis of forskolin].

Forskolin is a complex labdane plant diterpenoid, which has been used in the treatment of a variety of diseases based on its activity as an activator of adenosine monophosphate(cAMP) cyclase. Natural forskolin exists only in the cork layer of the root of Coleus forskohlii. Due to the complexity of the extraction and chemical synthesis processes, the yield and purity of forskolin cannot meet commercial requirements. In recent years, with the rapid development of synthetic biology and the analysis and interpretation of many diterpene biosynthetic pathways, a new approach has been provided for the green production of forskolin. In this paper, the structure, activity, biosynthetic pathway and the heterologous biosynthesis of forskolin were reviewed. The problems and solutions in the heterologous biosynthesis of forskolin were also discussed and summarized, which will provide references for the construction of high-yielding forskolin engineering strains.

[Discussion on multidisciplinary treatment mode of advanced schistosomiasis and its standardized implementation].

Advanced schistosomiasis is the most serious clinical type of schistosomiasis. Its diagnosis and treatment are related to many special departments, such as gastroenterology, general surgery, neurology, endocrinology, radiology, traditional Chinese medicine, blood purification, endoscopy, intervention, and ICU. It is necessary to apply a multidisciplinary treatment (MDT) mode. However, the mode has no universal standard and guide in practice. It is very important for the implementation of MDT mode of advanced schistosomiasis to form a treatment expert team, formulate the formal working procedures, and standardize the treatment schedules. The standardized implementation of MDT mode will be important to provide a more effective clinical decision on advanced schistosomiasis.

Cys74 and Cys163 are necessary for IL-18 to elicit IFN-gamma production from peripheral blood lymphoid mononuclear cells.

There are four cysteines (Cys74, Cys104, Cys112 and Cys163) in mature human IL-18 (hIL-18). These cysteines are highly conserved in IL-18s of 11 species cloned so far, suggesting that one or more of the cysteines may be important for hIL-18 function. In this study, each cysteine residue was individually replaced with serine by site-directed mutagenesis. The wild type and mutant IL-18s were expressed in Escherichia coli and renatured by two renaturing methods. The purified wild type and mutant rhIL-18s were assayed for their capacity of inducing IFN-gamma and activating NF-kappaB from ConA-stimulated PBMC. DNA binding activity of NF-kappaB was performed by electrophoretic mobility-shift analysis. Our results showed that the mutant rhIL-18C74S and C163S induced much less amount of IFN-gamma from PBMC and the decrement of NF-kappaB DNA binding activity was also observed from C74S and C163S treated PBMC. These results indicate that functional hIL-18 has an absolute requirement for residues Cys74 and Cys163.

[Correlation of bone marrow stromal function in vitro with efficacy of anisodamine therapy for aplastic anemia].

To observe normal bone marrow stromal function for supporting hematopoiesis and realize the correlation of bone marrow stromal function in patients with aplastic anemia (AA) and anisodamine therapy, normal human marrow CFU-GM was assayed on bone marrow stromal layer (SL) formed on week 3 culture, and the CFU-GM without SL as a control (100%). Results showed that the production of CFU-GM on the normal SL was significantly higher than that of the control. The production of CFU-GM on the SL of 4 AA patients, who responded to anisodamine, was < 80% of the control, and when 2 of them were reexamined for stromal function after treatment, the number of CFU-GM on SL rose up to 168.8% and 249.2% from 38.7% and 39.7% of the control respectively. While in the rest 6 patients, the number of CFU-GM was > 80% of the control, only one patient was improved by anisodamine therapy. So, normal bone marrow stromal layer can obviously support the growth of granulocyte/macrophage progenitor cells. Anisodamine therapy could be an effective agents for aplastic anemia with stromal dysfunction
