Fecal microbiota transplantation (FMT) technology originated in China during the Eastern Jin Dynasty and has rapidly developed over the past two decades, becoming a primary method for studying the causal relationship between gut microbiota and the occurrence and progression of diseases. At the same time, the therapeutic effects of FMT in the field of gastrointestinal diseases have gained widespread recognition and are gradually expanding into other disease areas. The FMT procedure is relatively complex, and there is currently no standardized method; its success is influenced by various factors, including the donor, recipient, processing of the fecal material, and the method of implantation. Given the increasingly recognized relationship between gut microbiota and various diseases, FMT has become a research hotspot in both scientific studies and clinical applications, achieving a series of significant advancements. To help researchers better understand this technology, this paper will outline the development history of FMT, summarize common operational methods in research and clinical settings, review its application progress, and look forward to future development directions.

OBJECTIVE To innovatively apply the pre-intelligent precision dosing and verification system (hereinafter referred to as “the system”), and to provide a reference for the high-level “intelligent” transformation of inpatient pharmacy. METHODS The limitations of the triple-serial dispensing mode, which comprised the automatic medicine packaging machine (ATC), intelligent tablet dispensing table (ITDT) and medication detection machine (MDM), were analyzed. The application of the system and the adoption of the barcode scanning verification method optimized the pre-dosing management, whole-tablet drug dispensing process and ATC temporary dosing management. The comparative analysis was conducted to assess dosing time, labor cost and packaging error of the eight-month period, before and after the system application. RESULTS The triple-serial dispensing mode had a weak ability to avoid error risks in the manual dosing stage, and also had errors in the verification stage. Through the innovative application system, the pre-dosing management had been upgraded, the whole-tablet drug dispensing process had been optimized, and the ATC temporary dosing management had been improved. The average time required for each drug for pre-dosing, whole-tablet drug dispensing and ATC temporary dosing was significantly shortened after the application of the system, compared with before the application of the system (P<0.001). The number of pharmacists was reduced from two to one. The error rate of ATC decreased significantly from 0.220‰ to 0.029‰ (P<0.001). Specifically, the rate of pharmacist-related errors (pre-dosing error, ITDT dosing error, and ATC temporary dosing error) decreased from 0.116‰ to 0.001‰ (P<0.001), and machine-related errors decreased from 0.096‰ to 0.023‰ (P<0.001). CONCLUSIONS This innovative integration mode greatly improves the working efficiency and quality of inpatient pharmacy. It enhances refined management of drug expiration and inventory, saves time and labor costs, improves the accuracy of drug dispensing, and ensures patient medication safety.

OBJECTIVE To investigate the induction of apoptosis in hepatocellular carcinoma cells by polyphyllin 9 (PP9) through the regulation of the Fas/Fas ligand (FasL) signaling pathway, and its inhibitory effect on the growth of transplanted tumor in nude mice. METHODS Based on the screening of cell lines and intervention conditions, HepG2 cells were selected as the experimental subject to investigate the effects of 2 μmol/L and 4 μmol/L PP9 treatment on cell colony formation activity, apoptosis rate, as well as the protein expressions of Fas, FasL, cleaved caspase-8 and cleaved caspase-3. Additionally, Fas inhibitor KR- 33493 was introduced to investigate the underlying mechanism of PP9’s anti-hepatocellular carcinoma activity. Using HepG2 cell tumor-bearing nude mice model as the object, and 5-fluorouracil (20 mg/kg) as the positive control, the effects of 10 mg/kg PP9 on tumor volume, tumor mass, and the protein expressions of the nuclear proliferation-associated antigen Ki-67 and cleaved caspase-3 in tumor-bearing nude mice were investigated. RESULTS Compared with the control group, 2, 4 μmol/L PP9 significantly decreased the number of clones and the clone formation rate of cells, but significantly increased the apoptosis rate, the protein expressions of Fas, FasL, cleaved caspase-8 and cleaved caspase-3 (P<0.05 or P<0.01). However, the combination of Fas inhibitor KR-33493 could significantly reverse the effect of PP9 on the up-regulation of proteins related to the Fas/FasL signaling pathway (P<0.01). Compared with the control group, the tumor volume (on day 27), mass and protein expression of Ki- 67 in nude mice of the PP9 group were significantly decreased, while the protein expression of cleaved caspase-3 was significantly increased (P<0.01). CONCLUSIONS PP9 can induce apoptosis of HepG2 cells by activating the Fas/FasL signaling pathway. Meanwhile, PP9 can also effectively inhibit the growth of transplanted tumors in nude mice.

AIM: To observe and analyze the effectiveness and safety of wearing corneal refractive therapy(CRT)and vision shaping treatment(VST)designed orthokeratology in controlling myopic progression in adolescents with low E-value corneal morphology.METHODS: This prospective study involved 100 cases(100 eyes)of adolescent myopia patients fitted with orthokeratology at our optometry clinic from January 2020 to December 2021. The data of right eye were collected for research, and they were divided into low myopia group(-1.00 to -3.00 D)and moderate myopia group(-3.25 to -5.00 D)according to spherical equivalent, with 50 cases in each group. Each group of patients was further randomly divided into the CRT group and the VST group, with 25 cases in each group. Uncorrected visual acuity, refractive error, axial length(AL), tear film break-up time(BUT), corneal endothelial cell density, corneal staining grading, lens decentration, and refractive power at 15°-30° were measured before and after wearing orthokeratology, with a follow-up duration of 1.5 a.RESULTS: The uncorrected visual acuity of CRT and VST subgroups in the low myopia group showed no statistical significance at any time point after wearing orthokeratology. However, in the moderate myopia group, CRT subgroup showed better uncorrected visual acuity than the VST subgroup, with significant differences at 1 d and 1 wk(t=-9.474, -12.067, both P<0.01); no significant differences were noted at other time points. After wearing lens for 6 mo and 1.5 a, the AL growth for the CRT subgroup in low and moderate myopia was less than the VST subgroup, with no statistically significant differences. There were no statistically significant differences in binocular BUT and corneal endothelial cell density after wearing lens for 6 mo and 1.5 a. Corneal injury was lower in the CRT subgroup than that in the VST subgroup, but the difference was not statistically significant(Z=-1.803, P=0.071). Lens decentration was significantly better in the CRT subgroup than in the VST subgroup(Z=-4.629, P<0.001). In the periphery of the retina at 15°-30°, there were no significant differences in the amount of myopic defocus between the two groups, while it was statistically significant at 1, 3, and 6 mo in the moderate myopia subgroup(t=-3.949, P=0.008; t=-5.833, P<0.001; t=-6.231, P<0.001), indicating that CRT subgroup could produce a greater amount of myopic defocus.CONCLUSION: For patients with low E-value corneal morphology, CRT, using the vector height at 8 mm on the cornea for fitting, is not limited to the corneal E-value. It shapes faster and improves uncorrected visual acuity after shaping, especially for moderate myopia, achieving better daytime vision. In terms of controlling myopia, CRT fitting elevates return zone depth(RZD), creating a small central optical zone to produce more peripheral myopic defocus. However, there was no significant difference between the two groups in controlling AL growth. Both groups showed minimal corneal damage, indicating consistent safety in myopia control.

Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine (TCM). The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology, Western medicine obstetrics and gynecology, and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion, the experts concluded that chromosome, endocrine, and immune abnormalities were the key factors for the occurrence of threatened abortion, and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion, TCM has advantages in preventing miscarriages, alleviating clinical symptoms and TCM syndromes, relieving anxiety, regulating reproductive endocrine and immune abnormalities, personalized and diversified treatment, enhancing efficiency and reducing toxicity, and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

Osteoarthritis (OA) is a common degenerative joint disease with a rising incidence rate year by year. Treatment often relies on analgesics and non-steroidal anti-inflammatory drugs (NSAIDs), which can lead to gastrointestinal damage with long-term use and the recurrence of symptoms. Chinese medicine has a long history of preventing and treating OA, with widespread application and fewer side effects. It offers unique advantages such as a broad treatment scope, multiple targets, and pathways. The effective components of Chinese medicine can reduce the content of reactive oxygen species (ROS), relieve oxidative stress (OS) damage, and increase the antioxidant capacity of the body by interfering with the expression of biomarkers of OS response such as malondialdehyde (MDA) and superoxide dismutase (SOD). Through the modulation of signaling pathways such as nuclear factor E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), nuclear factor kappa B (NF-κB), c-Jun N-terminal kinase (JNK), NOD-like receptor protein 3 (NLRP3), and osteoprotegerin (OPG), they downregulated the expression of inflammatory factors such as interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α), thereby effectively relieving local joint inflammation, protecting chondrocytes and bone tissue, inhibiting chondrocyte apoptosis, and further alleviating the progression of OA. Currently, there are still certain limitations in the medical research status and development trends of OA, necessitating the continued advancement of traditional Chinese medicine. This paper reviewed the literature on the regulation of OS response by effective components of Chinese medicine for the prevention and treatment of OA, providing new directions and ideas for future research.
