Chinese Journal of Biologicals 2026;39(03):370-373+384
During routine Good Manufacturing Practice(GMP) compliance supervision, periodic inspections based on risk control concepts have revealed gaps between the current practices of biologics manufacturers in Jilin Province and the latest domestic and international regulatory standards. These gaps span multiple areas, including facility and equipment design for aseptic product manufacturing, airflow pattern control, cleaning and disinfection practices, environmental monitoring, aseptic process simulation, and personnel gowning procedures. This paper compiles and analyzes these identified issues. Considering the inherent tendency of biological product components to support microbial growth, and based on recent regulatory updates alongside a statistical analysis of aseptic manufacturing deficiencies observed during GMP compliance inspections in Jilin's biologics sector, this paper discusses the future direction for improving aseptic assurance levels. The aim is to provide theoretical support for both future regulatory efforts and the enhancement of aseptic assurance capabilities within enterprises.

Hepatocellular carcinoma (HCC) is a common malignant tumor with a high fatality rate worldwide, with limited overall survival benefits and pronounced drug resistance issues, highlighting the urgent need for novel sensitization strategies and patient stratification systems. Ferroptosis, as an iron-dependent form of lipid peroxidation-driven cell death, is closely associated with tumor treatment responses. In addition to the classic glutathione peroxidase 4 (GPX4)/glutathione (GSH) pathway, the ferroptosis suppressor protein 1 (FSP1)-coenzyme Q10 (CoQ10) pathways and the dihydroorotate dehydrogenase (DHODH) pathway are two newly identified anti-ferroptosis pathways that function at the plasma membrane and mitochondria, respectively, and determine cellular sensitivity to ferroptosis in synergy with GPX4. This article systematically reviews the mechanism of action of the FSP1-CoQ10 and DHODH pathways in HCC and related research advances, proposes related therapeutic strategies, and look forward to its clinical translation and application prospects.

ObjectiveTo clarify the neuroprotective effect of black Panacis Quinquefolii Radix(PQR) and explore its active ingredients, with the aim of establishing an activity-oriented quality evaluation method. MethodsTransgenic Tg(HuC∶EGFP) zebrafish was used to establish a neuronal injury model by aluminum chloride immersion. Different doses(10, 20 mg·L-1) of PQR and black PQR ethanol extracts were administered. The neuroprotective effects of PQR and black PQR were compared by analyzing the fluorescent area and intensity of zebrafish neurons. Based on ultra-performance liquid chromatography(UPLC), a fingerprint profile of black PQR was established, followed by principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA). Differential components were screened using the criteria of variable importance in the projection(VIP) value>1 and P<0.05. The neuroprotective activity of 14 batches of black PQR was assessed, and Spearman correlation analysis was used to identify saponins related to neuroprotective activity, which were then validated. Based on the above results, active marker components were determined, and an UPLC method was established for their quantitation with clear content limits. ResultsPharmacological efficacy results showed that both PQR and black PQR at different doses could significantly improved neuronal damage in zebrafish. At a dose of 20 mg·L-1, black PQR demonstrated superior efficacy(P<0.05). The fingerprint similarities of 14 batches of black PQR were>0.94, with 26 common peaks identified. Through comparison with the reference standards, 8 components were confirmed, including peak 1(ginsenoside Rg1), peak 2(ginsenoside Re), peak 5(ginsenoside Rb1), peak 9(ginsenoside Rd), peak 16[ginsenoside 20(S)-Rg3], peak 17[ginsenoside 20(R)-Rg3], peak 18(ginsenoside Rk1), and peak 19(ginsenoside Rg5). The results of PCA and OPLS-DA indicated that there were differences in saponins among black PQR samples from different origins, and 12 differential components were screened. All 14 batches of black PQR exhibited good protective effects on zebrafish neurons, with Shaanxi-produced black PQR showing superior protective effects compared to the other three production regions. Spearman correlation analysis revealed that a total of 11 components, including ginsenosides 20(S)-Rg3, 20(R)-Rg3, Rk1 and Rg5, showed a significant positive correlation with the neuroprotective effect in zebrafish(P<0.05). The activity validation results indicated that ginsenosides 20(S)-Rg3, 20(R)-Rg3, Rk1 and Rg5 were the primary components responsible for the neuroprotective effects of black PQR. Quantitative analysis showed that the content of ginsenoside 20(S)-Rg3 in 14 batches of black PQR ranged from 0.17% to 0.52%, and the repair rate of neuronal damage ranged from 42.77% to 97.83%. ConclusionBased on the fingerprint and neuronal protective activity, the spectrum-effect related quality control model of black PQR was established, with ginsenoside 20(S)-Rg3 as the quality control index, and the neuronal damage repair rate≥60% as the evaluation standard, the minimum limit of ginsenoside 20(S)-Rg3 in black PQR should be≥0.20%.

ObjectiveTo assess the quality consistency of black Panacis Quinquefolii Radix(bPQR) decoction pieces prepared by atmospheric and pressurized steaming processes based on chromaticity-chemical composition-vasoactive inhibition. The ultimate goal was to screen the pressurized steaming process yielding quality equivalent to atmospheric steaming, and optimize the processing technology of bPQR. MethodsThe bPQR decoction pieces were prepared using both atmospheric and pressurized steaming processes, and the chromaticity values[lightness value(L*), red/green chromaticity value(a*), yellow/blue chromaticity value(b*), total chromaticity value(E*ab)] were measured. High performance liquid chromatography(HPLC) was employed to establish fingerprint profiles for the decoction pieces, and cluster analysis was conducted on chromaticity values and the common peak areas in fingerprint profiles to elucidate the quality relationships between the decoction pieces processed by different methods. The optimal atmospheric steaming of bPQR decoction pieces was determined through zebrafish angiogenesis inhibition experiments. The contents of ginsenosides Rg1, Re, Rb1, 20(S)-Rg3, Rk1 and Rg5 in the decoction pieces were quantified, and Spearman correlation analysis was employed to investigate the relationship between saponin content, chromaticity, and angiogenesis inhibition activity during the steaming process. By integrating the consistency of chromaticity, saponin components and angiogenesis inhibition activity, pressurized steaming conditions with quality equivalent to the atmospheric pressure method were selected. ResultsCompared with the atmospheric steaming method, pressurized steaming resulted in faster color darkening and higher conversion rates of ginsenosides in bPQR decoction pieces. Moreover, the neovascularization inhibitory activity of bPQR decoction pieces continued to increase with the deepening of processing. Based on the effectiveness and safety, the optimal process for preparing bPQR decoction pieces with neovascularization inhibitory activity was determined to be atmospheric steaming for 21 h. All six ginsenosides tested exhibited strong to extremely strong correlations with both the chromaticity values of the decoction pieces and their neovascularization inhibitory activities. Among them, ginsenosides Rg1, Re and Rb1 exhibited positive correlations with chromaticity values and negative correlations with zebrafish angiogenesis inhibition activity. Conversely, ginsenosides 20(S)-Rg3, Rk1 and Rg5 showed negative correlations with chromaticity values and positive correlations with zebrafish angiogenesis inhibition activity. By integrating chromaticity values, cluster analysis results, as well as the results of activity, it was determined that the quality of bPQR decoction pieces steamed under pressurized conditions of 110 ℃(0.045 MPa) for 5 h and 115 ℃(0.07 MPa) for 3 h was highly consistent with that obtained by atmospheric steaming for 21 h. ConclusionThe preparation of bPQR decoction pieces by pressurized steaming has the advantages of short preparation time, low energy consumption, and rapid saponin conversion rate, making it a viable alternative to atmospheric steaming for preparing bPQR decoction pieces. Meanwhile, the evaluation method based on chromaticity-chemical composition-activity can provide a more scientific and effective explanation of change rules in the quality during traditional Chinese medicine processing, and offer a new model for optimizing processing technology and enhancing quality control.

Xiao Chaihutang, originating from the Treatise on Typhoid and Miscellaneous Diseases, is a classic formula for harmonizing the Shaoyang. It excels in regulating the pivotal mechanism and unblocking the triple energizer, corresponding to the pathogenesis of digestive system tumors characterized by the interlocking of deficiency, stasis, phlegm, and toxicity, as well as disharmony between Yin and Yang. This paper systematically reviews research findings from China and abroad over the past decade, exploring the anti-tumor effects of Xiao Chaihutang on digestive system tumors from three dimensions: theoretical rationale, clinical efficacy, and molecular mechanisms. At the level of principle and method, Xiao Chaihutang takes "harmonization" as its core therapeutic guideline. By reconciling the exterior and interior to restore the Shaoyang pivot, harmonizing Yin and Yang to improve the tumor microenvironment, and regulating the liver and spleen to consolidate and protect the foundation of postnatal essence, it promotes the restoration of the body's dynamic balance of Yin and Yang. Clinical studies have demonstrated that Xiao Chaihutang, used alone or in combination with modern medical therapies, shows definite efficacy against digestive system tumors such as hepatocellular carcinoma, pancreatic carcinoma, and gastrointestinal carcinoma. It can significantly improve patients' quality of life, inhibit tumor progression, effectively relieve concomitant symptoms such a s cancer-related fever, anxiety, depression, and insomnia, and alleviate postoperative embolic syndromes as well as adverse reactions to radiotherapy and chemotherapy. Experimental studies have revealed that Xiao Chaihutang can inhibit tumor cell proliferation, induce apoptosis, arrest the cell cycle, suppress tumor cell invasion and metastasis, and improve the tumor microenvironment. Through the above analysis, this study elucidates the current clinical and experimental research status of Xiao Chaihutang in the treatment of digestive system tumors, aiming to provide theoretical support for its precise clinical application. On this basis, it further explores key issues in the identification of pharmacodynamic substances and the accumulation of evidence in evidence-based medicine, thereby offering a new perspective for the innovative development of integrative Chinese and Western medicine in synergistic cancer therapy.

The Fragment of Dunhuang Ancient Tibetan Moxibustion Therapy contains rich content on fire moxibustion therapy of Tubo-period Tibetan medicine, characterized by distinctive clinical features of Tibetan acupuncture and strong regional attributes. This paper systematically reviews the relevant materials on moxibustion in the Fragment and summarizes the findings as follows: Tibetan fire moxibustion mainly uses mugwort as the material, and terms like "fine mugwort", "broad bean" and "sheep dung pellet" refer to the size of the moxa cone. The number of moxa cones used is predominantly odd numbers, usually ranging from 5 to 21. The main indications for fire moxibustion cover internal medicine, external medicine, gynecology, pediatrics, and various pain syndromes. The therapy advocates for treating acute conditions and heat syndromes with moxibustion. The manuscript also records detailed contraindications, including time-based and seasonal taboos. Moxibustion is applied to both local and distal acupoints, reflecting the therapeutic concept of treating both proximal and distal regions. Furthermore, it documents simple and practical acupoint localization methods such as surface anatomical markers, proportional bone measurement, finger measurement, and hand-span measurement. Compared with contemporaneous Chinese medical moxibustion techniques, the moxibustion methods recorded in this Fragment are rich in content and present unique Tibetan theoretical characteristics. It provides valuable data and evidence for the excavation, application, and further research of Tibetan acupuncture and moxibustion.
