Continuous manufacturing, as an innovative pharmaceutical production model, offers advantages such as high production efficiency and ease of control compared to traditional batch production, aligning with the future trend of drug production moving toward greater efficiency and intelligence. However, the development of continuous manufacturing technology in wet granulation has been slow. On one hand, this is closely related to its high technical complexity, substantial equipment investment costs, and stringent process control requirements. On the other hand, the long-term use of the traditional batch production model has created strong path dependence, and the lack of mature standardized processes further increases the difficulty of technological transformation. To promote the deep integration of wet granulation technology with continuous manufacturing, this review systematically outlines the current application of wet granulation in continuous manufacturing. It focuses on the development of key technologies such as online detection, process modeling, and process scale-up, with the aim of providing a reference for process innovation and application in wet granulation.

The study aims to elucidate the existence forms(original constituents and metabolites) of Notoginseng Radix et Rhizoma in rats and reveal its metabolic pathways. After Notoginseng Radix et Rhizoma was administered orally once a day for seven consecutive days to rats, all urine and feces samples were collected for seven days, while the blood samples were obtained 6 h after the last administration. Using the ultra high performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UHPLC-Q-TOF-MS/MS) technique, this study identified 6, 73, and 156 existence forms of Notoginseng Radix et Rhizoma in the rat plasma, urine, and feces samples, respectively. Among them, 101 compounds were identified as new existence forms, and 13 original constituents were identified by comparing with reference compounds. The metabolic reactions of constituents from Notoginseng Radix et Rhizoma were mainly deglycosylation, dehydration, hydroxylation, hydrogenation, dehydrogenation, acetylation, and amino acid conjugation. Furthermore, the possible in vivo metabolic pathways of protopanaxatriol(PPT) in rats were proposed. Through comprehensive analysis of the liquid chromatography-mass spectrometry(LC-MS) data, isomeric compounds were discriminated, and the planar chemical structures of 32 metabolites were clearly identified. According to the literature, 48 original constituents possess antitumor and cardiovascular protective bioactivities. Additionally, 32 metabolites were predicted to have similar bioactivities by SuperPred. This research lays the foundation for further exploring the in vivo effective forms of Notoginseng Radix et Rhizoma.

BACKGROUND: A growing body of research is exploring the role of antioxidant and anti-inflammatory dietary supplements in the treatment of osteoarthritis, highlighting an increasing emphasis on non-pharmacological interventions. Although more patients are turning to supplements to manage osteoarthritis, their actual effectiveness remains uncertain. OBJECTIVE: This study aims to provide a comprehensive evaluation of the available evidence concerning the efficacy of various dietary supplements in osteoarthritis treatment. SEARCH STRATEGY: We searched PubMed, Embase, Cochrane Library and Web of Science for studies on the use of various dietary supplements in the treatment of osteoarthritis from the creation of each database until Jan 20, 2025. INCLUSION CRITERIA: (1) Research object: osteoarthritis. (2) Intervention measures: patients in the treatment group received dietary supplements, while the control group received placebos. (3) Research type: randomized controlled trials (RCTs). DATA EXTRACTION AND ANALYSIS: Two researchers independently examined the literature and retrieved data based on predefined criteria. The information gathered included the first author, year of publication, sample size, participant demographics, length of the follow-up period, intervention and control measures, and inclusion indications. RCTs comparing dietary supplements to placebo with the pain and function subscales of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) among patients with osteoarthritis were included. The optimal dietary supplement was identified based on the total ranking by summing the surface under the cumulative ranking curve (SUCRA) of these two scores. Furthermore, the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to confirm the quality of the evidence. RESULTS: Overall, 23 studies covering 21 dietary supplements and involving 2455 participants met the inclusion criteria. In the WOMAC pain score, the SUCRA of passion fruit peel extract was 91% (mean difference [MD]: -9.2; 95% confidence interval [CI]: [-16.0, -2.3]), followed by methylsulfonylmethane (89%), undenatured type II collagen (87%), collagen (84%), and Lanconone (82%). The SUCRA (99%) of passion fruit peel extract (MD: -41.0; 95% CI: [-66.0, -16.0]) ranked first in terms of the WOMAC function score, followed by Lanconone (95%), collagen (86%), ParActin (84%), and Lactobacillus casei strain Shirota (83%). The top three total rankings are passion fruit peel extract (95.0%), Lanconone (88.5%), and collagen (85.0%). However, the GRADE revealed low evidence quality. CONCLUSION Passion fruit peel extract was the best supplement for improving WOMAC pain and function scores in patients with osteoarthritis, followed by Lanconone and collagen. However, further large-scale, well designed RCTs are required to substantiate these promising findings.

Objective:To explore the correlation between peripheral blood B cell count and clinical features and prognosis of patients with newly diagnosed diffuse large B-cell lymphoma(DLBCL).Methods:The relationship of peripheral blood B cell count with clinical features,laboratory indexes and prognosis in 67 patients with newly diagnosed DLBCL was retrospectively analyzed.Results:Patients were divided into low B-cell count group(B cell＜0.1 × 109/L,n=34)and high B-cell count group(B cell≥0.1 × 109/L,n=33)according to the median B cell count values.Compared with the high B cell count group,the low B cell count group had a higher proportion of patients with Lugano stage Ⅲ-Ⅳ,elevated LDH,elevated β2-MG and IPI score 3-5 and increased CRP(P=0.033,0.000,0.023,0.001,0.033).The peripheral CD3+and CD4+cell counts of patients in the low B cell count group were significantly lower than those in the high B cell count group(P=0.010,0.017).After initial treatment,overall response rate(ORR)and complete remission(CR)rate in high B cell count group were significantly higher than those in low B cell count group(P=0.032,0.013).The median follow-up time of patients was 23(2-77)months,progression-free survival(PFS)and overall survival(OS)of patients in the high B cell count group were significantly better than those in the low B cell count group(P=0.001,0.002).Univariate analysis showed that pretreatment low B cell count in the peripheral blood was associated with shortened PFS and OS(HR=4.108,P=0.002;HR=8.218,P=0.006).Multivariate analysis showed that low B cell count was an independent prognostic factor for shortened PFS(HR=3.116,P=0.037).Conclusion:Decreased peripheral blood B cell count in newly diagnosed DLBCL patients is associated with high-risk clinical features and may affect the efficacy of immunochemotherapy,which is associated with poor clinical prognosis.

Objective:To investigate distribution and drug resistance of pathogens of bloodstream infection in patients with hematological malignancies,in order to provide reference for clinical infection control and treatment.Methods:The clinical information of blood culture patients in the hematology department of our hospital from January 2016 to December 2021 was reviewed.They were divided into transplantation group and non-transplantation group according to whether they had undergone hematopoietic stem cell transplantation.The types of pathogens and their drug resistance were analyzed.Results:Two hundred and ninety-nine positive strains of pathogenic bacteria were detected.In the transplantation group,Gram-negative bacteria accounted for 68.5％(50/73),Gram-positive bacteria accounted for 6.8％(5/73),and fungi accounted for 24.7％(18/73).The resistance rate of Escherichia coli to the third-generation cephalosporins was 77.8％,and 11.5％to carbapenems.The resistance rate of Klebsiella pneumoniae to the third-generation cephalosporins was 50.0％,and 56.2％to carbapenems.In the non-transplantation group,Gram-negative bacteria accounted for 64.1％(145/226),Gram-positive bacteria accounted for 31.0％(70/226),and fungi accounted for 4.9％(11/226).Gram-positive bacteria were mainly Enterococcus faecium(6.6％,15/226)and Coagulase-negative Staphylococci(6.2％,14/226).The fungi were all Candida tropicalis.The resistance rate of Escherichia coli to the third-generation cephalosporins was 63.8％,and 10.3％to carbapenems.The resistance rate of Klebsiella pneumoniae to the third-generation cephalosporins was 46.3％,and 26.8％to carbapenems.Conclusion:The types of pathogenic bacteria in bloodstream infection in patients with hematological malignancies are varied.Gram-negative bacteria is the main pathogenic bacteria.The resistance of pathogenic bacteria to antibiotics is severe.Antibiotics should be used scientifically and reasonably according to the detection and resistance of pathogenic bacteria.

【Objective】 To investigate the correlation of the levels of interleukin-25 (IL-25) and interleukin-33 (IL-33) in cord blood with the development of infantile eczema within 42 days after birth, so as to provide theoretical support for the prevention of early infant eczema. 【Methods】 A total of 145 newborns who met the inclusion criteria and were born in the Obstetrics and Gynecology Department of the Air Force Special Medical Center from September 2020 to September 2021 were selected. Cord venous blood was collected at birth and the levels of IL-25 and IL-33 in cord blood were measured. The occurrence and severity of infantile eczema were recorded in 42 days. 【Results】 Among 145 infants, 79(54.5%) suffered from eczema. The level of IL-25 in cord blood in eczema group was significantly lower than that in non-eczema group (Z=4.957, P<0.001), and the level of IL-33 in cord blood in eczema group was significantly higher than that in non-eczema group (Z=4.594, P<0.001). The proportion of family history of allergy in the eczema group was significantly higher than that in non-eczema group (χ²=4.693, P<0.05). Logistic regression analysis showed that family history of allergy (OR=4.296), lower level of IL-25(<14.5pg/mL) (OR=4.034) and higher level of IL-33(>21.1pg/mL) (OR=2.759) in cord blood were risk factors for eczema (P<0.05), while birth weight was not associated with the onset of eczema in infants at 42 days (P>0.05). Meanwhile, the level of IL-33 in cord blood was related to the mode of delivery (P<0.05). ROC analysis showed that the optimized positive cutoff value was <14.0pg/mL for cord blood IL-25(sensitivity 62.0%, specificity 75.8%) and >22.1pg/mL for IL-33 (sensitivity 64.6%, specificity 69.7%). Spearman correlation test found that there was a linear correlation of the level of cord blood IL-33 with eczema area and severity index (EASI) score (r=0.398, P<0.01). 【Conclusion】 Family allergy history, lower level of cord blood IL-25 and higher level of cord blood IL-33 are important influencing factors of infant eczema in 42 days after birth, and higher level of cord blood IL-33 will aggravate the severity of early infantile eczema.

Objective This study aimed to evaluate whether the onset of the plateau phase of slow hepatitis B surface antigen decline in patients with chronic hepatitis B treated with intermittent interferon therapy is related to the frequency of dendritic cell subsets and expression of the costimulatory molecules CD40,CD80,CD83,and CD86. Method This was a cross-sectional study in which patients were divided into a natural history group(namely NH group),a long-term oral nucleoside analogs treatment group(namely NA group),and a plateau-arriving group(namely P group).The percentage of plasmacytoid dendritic cell and myeloid dendritic cell subsets in peripheral blood lymphocytes and monocytes and the mean fluorescence intensity of their surface costimulatory molecules were detected using a flow cytometer. Results In total,143 patients were enrolled(NH group,n = 49;NA group,n = 47;P group,n = 47).The results demonstrated that CD141/CD1c double negative myeloid dendritic cell(DNmDC)/lymphocytes and monocytes(%)in P group(0.041[0.024,0.069])was significantly lower than that in NH group(0.270[0.135,0.407])and NA group(0.273[0.150,0.443]),and CD86 mean fluorescence intensity of DNmDCs in P group(1832.0[1484.0,2793.0])was significantly lower than that in NH group(4316.0[2958.0,5169.0])and NA group(3299.0[2534.0,4371.0]),Adjusted P all<0.001. Conclusion Reduced DNmDCs and impaired maturation may be associated with the onset of the plateau phase during intermittent interferon therapy in patients with chronic hepatitis B.

The adulteration and counterfeiting of herbal ingredients in medicinal and food homology (MFH) have a serious impact on the quality of herbal materials, thereby endangering human health. Compared to pharmaceutical drugs, health products derived from traditional Chinese medicine (TCM) are more easily accessible and closely integrated into consumers' daily life. However, the authentication of the authenticity of TCM ingredients in MFH has not received sufficient attention. The lack of clear standards emphasizes the necessity of conducting systematic research in this area. This study utilized DNA barcoding technology, combining ITS2, psbA-trnH, matK as universal barcode sequences, and DX, HH, JYH as specific barcode sequences, to identify the authenticity of commercial medicinal and food homology scented herbal teas. The aim was to investigate the authenticity of scented herbal tea products circulating in the market. The research results revealed that among 180 scented herbal tea samples, DNA barcodes were successfully obtained from 164 samples, while the remaining samples either lacked the target components or suffered severe DNA degradation, resulting in failed amplification. Combined with morphological identification studies, it was found that out of the 180 samples, 141 were authentic, accounting for 78.33% of the total samples, while 31 samples showed adulteration and 8 samples lacked the target components, accounting for 21.67% of the total samples. Additionally, water testing revealed that 5 samples of Carthamus tinctorius herbal tea exhibited the phenomenon of weight adulteration. This study exposed the presence of adulteration and weight adulteration in scented herbal tea products, highlighting the need for regulatory authorities to expedite the establishment of quality standards in scented herbal tea industry. These findings provide valuable insights for the rapid development of the scented herbal tea industry.

Objective To investigate the efficacy and safety of a new type of self-made bone drill applied to percutaneous transforaminal endoscopic discectomy for L5/S1 intervertebral disc herniation.Methods The clinical data of 52 patients with L5/S1 intervertebral disc herniation admitted to our hospital were retrospectively analyzed.All patients underwent percutaneous transforaminal endoscopic discectomy,with a new type of self-made bone drill for foraminoplasty during the surgery.The surgical conditions and occurrence of complications were recorded.The pain of patients before surgery,3 days after surgery,3 months after surgery,6 months after surgery,and 1 year after surgery was assessed by visual analogue scale(VAS);and the neurological function improvement before and after surgery was evaluated by Oswestry disability index(ODI).Results All patients underwent successful surgery without serious complications or recurrence after surgery.The VAS and ODI scores of patients 3 days,3 months,6 months,and 1 year after surgery were significantly lower than those before surgery(P<0.05).Conclusion The self-made new bone drill can significantly improve the efficiency of foraminoplasty and ensure surgical safety,with satisfactory early clinical effect.

Objective To evaluate the safety of human purified Vero cell rabies vaccine(PVRV)after exposure in China by Meta-analysis.Methods With rabies,vaccine and safety as key words,a systematic search was performed in PubMed,EMBASE,Cochrane and China National Knowledge Infrastructure(CNKI),supplemented by manual retrieval.A Meta-analysis was performed to analyze the incidence of adverse events of two immunization regimens Zagreb and Essen using Review Manager 5.4 software after literature screening and data extraction according to the inclusion and exclusion criteria.Results A total of 12 studies were included,of which 7 were prospective studies and 5 were retrospective studies.Most included in the studies showed a low risk of bias.The incidence of adverse events in Zagreb regimen was significantly higher than that in Essen regimen[relative risk(RR)= 1.01,95% CI = 0.90 ～ 1.14;I2= 73.00%,P<0.05],but there was a high degree of heterogeneity.The incidence of fever,pain and induration in Zagreb regimen was significantly higher than that in Essen regimen(RR = 1.14,0.92 and 0.86,95% CI = 0.82 ～ 1.60,0.73 ～ 1.14 and 0.29 ～ 2.51;I2= 73.00%,P<0.05],but there was a high degree of heterogeneity.The incidence of fever,pain and induration in Zagreb regimen was significantly higher than that in Essen regimen(RR = 1.14,0.92 and 0.86,95% CI = 0.82 ～ 1.60,0.73 ～ 1.14 and 0.29 ～ 2.51;I2= 81%,65% and 92%,respectively,P<0.01).Conclusion Two regimens of PVRV vaccination after exposure showed good safety.However,when adopting Zagreb regimen,attention should be paid to the physical conditions of children and the elderly with relatively poor immunity to avoid adverse events.
