A retrospective analysis of the clinical data of seven acute B-lymphoblastic leukemia (B-ALL) patients with TCF3-HLF fusion gene-positive admitted to the First Affiliated Hospital of Soochow University from June 2017 to August 2022 was conducted to summarize their clinical features and prognoses. The seven B-ALL patients comprised four males and three females, with a median age of 18 (11-33) years. Five patients tested positive for CD33 expression, and four patients had a normal karyotype. Two patients had hypercalcemia at the initial diagnosis, and one patient developed hypercalcemia at relapse. Six patients presented with coagulation dysfunction at diagnosis. After induction chemotherapy, five out of seven patients achieved complete remission, of which four subsequently relapsed. Two patients did not achieve remission even after two rounds of induction chemotherapy, with one achieving complete remission after treatment with blinatumomab immunotherapy. Three patients underwent chimeric antigen receptor T cell therapy, whereas three patients subsequently underwent hematopoietic stem cell transplantation. Five patients died, while two patients survived with sustained complete remission. TCF3-HLF-positive B-ALL is rare and has a high relapse rate and poor prognosis.

Pulmonary fibrosis(PF)is a chronic progressive end-stage lung disease.However,the mechanisms un-derlying the progression of this disease remain elusive.Presently,clinically employed drugs are scarce for the treatment of PF.Hence,there is an urgent need for developing novel drugs to address such diseases.Our study found for the first time that a natural source of Prismatomeris connata Y.Z.Ruan(Huang Gen,HG)ethyl acetate extract(HG-2)had a significant anti-PF effect by inhibiting the expression of the transforming growth factor beta 1/suppressor of mothers against decapentaplegic(TGF-β1/Smad)pathway.Network pharmacological analysis suggested that HG-2 had effects on tyrosine kinase phosphorylation,cellular response to reactive oxygen species,and extracellular matrix(ECM)disassembly.Moreover,mass spec-trometry imaging(MSI)was used to visualize the heterogeneous distribution of endogenous metabolites in lung tissue and reveal the anti-PF metabolic mechanism of HG-2,which was related to arginine biosyn-thesis and alanine,asparate and glutamate metabolism,the downregulation of arachidonic acid meta-bolism,and the upregulation of glycerophospholipid metabolism.In conclusion,we elaborated on the relationship between metabolite distribution and the progression of PF,constructed the regulatory metabolic network of HG-2,and discovered the multi-target therapeutic effect of HG-2,which might be conducive to the development of new drugs for PF.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors, with rapid progression and a poor prognosis. More and more studies have shown that there are small open reading frames (sORFs) on the molecular sequences of a large number of non-coding RNAs (ncRNAs), which can encode conserved peptides that play an important role in controlling the occurrence and development of HCC. This article introduces the discovery, prediction, and validation methods of ncRNA-encoding polypeptides and reviews its research progress, with the aim of providing new targets and ideas for early-stage diagnosis, targeted therapy, and prognosis assessment of HCC.

Background Work-related musculoskeletal disorders (WMSDs) are one of the major occupational health problems in the world. Pharmaceutical industry is an important part of China's national economy. At present, there are few related studies reported at home and abroad. Objective To investigate the status and influencing factors of WMSDs in chemical pharmaceutical industry. Methods A cross-sectional epidemiological survey was conducted among all workers from three chemical pharmaceutical enterprises in Guangzhou. The Musculoskeletal Disorders Questionnaire was used to collect information on demographic characteristics, symptoms of musculoskeletal disorders, types of work, work organization, and and work postures. Multiple logistic regression method was used to analyze the risk factors of WMSDs in chemical pharmaceutical workers. Results In this study, 563 workers were selected as subjects. The total prevalence rate of WMSDs symptoms in the chemical pharmaceutical workers was 43.9% (247/563), and the leading body part-specific prevalence rate from high to low was 34.3% in the lower back, 24.3% in the upper back, 24.0% in the shoulders, and 23.8% in the neck. The prevalence rate of WMSDs symptoms in multiple body parts (30.0%) was 2.16 times higher than that in single body part (13.9%), and the prevalence rate of WMSDs symptoms in four body parts was the highest (11.4%). The results of multiple logistic regression analysis showed that age ≥50 years (reference age <30 years) (OR=2.140, 95%CI: 1.054-4.345), often or very often (reference never/rarely) long-time head rotating (OR=2.695, 95%CI: 1.753-4.142) and long-time keeping arms above shoulders (OR=1.902, 95%CI: 1.108-3.265) increased the risk of reporting WMSDs symptoms (P<0.05). Regarding education level, workers with high school and technical secondary school (OR=0.333, 95%CI: 0.175-0.636) or college and above (OR=0.413, 95%CI: 0.216-0.790) education had a lower risk of reporting WMSDs symptoms than those with middle school or below (P<0.05). Conclusion The prevalence rate of reporting WMSDs symptoms in chemical pharmaceutical industry is high, the involving body parts are lower back, upper back, shoulders, and neck, and reporting simultaneous occurrence of WMSDs symptoms in multiple body parts is common. The chemical pharmaceutical manufacturers can reduce the risk of WMSDs by strengthening the training on workers' ergonomics knowledge, paying attention to the less educated personnel, protecting the elderly workers, and avoiding awkward work postures, like rotating head for a long time and raising arms over shoulders.

OBJECTIVE To study the protective effects of ligustrazine-scutellarein twin drug ST-11 on rat adrenal medullary pheochromocytoma PC12 cell injury induced by oxygen-glucose deprivation/reperfusion (OGD/R) and its mechanism. METHODS PC12 cells were divided into blank group, model group, nimodipine group (positive control, 5 μmol/L) and different concentration groups of ST-11 (5, 10, 20 μmol/L). After 24 hours of pre-administration intervention, all the other groups except the blank group were cultured in glucose-free DMEM culture medium containing 10 mmol/L Na2S2O4 for 4 hours with glucose deficiency and hypoxia. After 4 hours of glucose and oxygen re-introduction, the survival rate of cells in each group, the contents of lactate dehydrogenase (LDH), catalase (CAT), glutathione (GSH), malondialdehyde (MDA) and superoxide dismutase (SOD) in cell supernatant, apoptosis rate, the levels of reactive oxygen species (ROS) and mitochondrial membrane potential (MMP), the protein expressions of B-cell lymphoma 2 related X protein (Bax), B-cell lymphoma 2 (Bcl-2) and caspase-3 were all detected in each group. RESULTS Compared with blank group, the cell survival rate, the contents of CAT, GSH and SOD in cell supernatant, MMP level, relative expression of Bcl-2 and Bcl-2/Bax ratio in model group decreased significantly (P<0.05), while the contents of LDH and MDA, ROS level, apoptosis rate, relative expressions of Bax and caspase-3 were significantly increased (P<0.05). Compared with model group, above indexes of ST-11 groups (except for the protein expression of caspase-3 in 5 μmol/L ST-11 group) were reversed signifi-cantly (P<0.05). CONCLUSIONS ST-11 has a certain protec-tive effect on OGD/R-injured PC12 cells, and its effects may be related to reduction of oxidative stress and inhibition of cell apoptosis.

OBJECTIVE To study the protective effects of twin drugs of tetramethylpyrazine-scutellarein (TMSC4) on cerebral ischemia-reperfusion injury (CIRI) model rats and its mechanism. METHODS One hundred and five SD rats were randomly divided into sham operation group, model group, scutellarein group (0.7 mmol/kg), tetramethylpyrazine group (0.7 mmol/kg), and TMSC4 low-dose, medium-dose and high-dose groups (0.35, 0.7, 1.4 mmol/kg), with 15 rats in each group. Sham operation group and model group were given constant volume of normal saline intragastrically, and other groups were given relevant drug intragastrically, once a day, for consecutive 14 d. Except for sham operation group, all other groups were treated to establish the CIRI model using the thread occlusion method. After 2 hours of ischemia and 22 hours of reperfusion, the brain index and brain water content of the rats were measured. Serum levels of interleukin 1β (IL-1β), IL-6 and tumor necrosis factor α (TNF-α), the levels of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px) and catalase (CAT) in brain tissues, the situation of neuronal cell apoptosis, and the protein expressions of B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax) and cleaved-caspase-3 were evaluated. RESULTS Compared with sham operation group, the brain index, brain water content, the serum levels of IL-1β, IL-6 and TNF-α, the levels of MDA in brain tissues, the brain cell apoptosis and the protein expressions of Bax and cleaved-caspase-3 in model group were significantly increased (P<0.05); the levels of SOD, GSH- Px and CAT and the protein expression of Bcl-2 in brain tissues were significantly decreased (P<0.05). Compared with model group, the above indexes of rats were reversed significantly in administration groups (P<0.05), while the reverse effects of TMSC4 medium-dose and high-dose groups were significantly better than those of scutellarein group and tetramethylpyrazine group (P<0.05). CONCLUSIONS TMSC4 has a certain protective effect in CIRI model rats, the mechanism of which may be related to relieving inflammatory reaction and oxidative stress, inhibiting cell apoptosis.

{L-End}Objective To analyze the prevalence of multi-site work-related musculoskeletal disorders (WMSDs) and their influencing factors among workers in the chemical pharmaceutical industry. {L-End}Methods A total of 563 workers from three chemical pharmaceutical factories in Guangzhou City were selected as the research subjects using the judgment sampling method. The prevalence of multi-site WMSDs in the past 12 months was investigated using the electronic questionnaire of Chinese Version of Musculoskeletal Disorders Questionnaire. {L-End}Results The prevalence of multi-site WMSDs in the research subjects was 30.0% (169/563). The results of multivariable logistic regression analysis showed that workers who smoked regularly/frequently and those who had their hands above shoulder level for long periods of time had a lower risk of multi-site WMSDs than those who never/occasionally smoked (all P≤0.05). Workers with a high school, secondary specialty, college degree, or above had a lower risk of multi-site WMSDs than those with a middle school education or below (all P<0.05). The longer the daily working hours, the higher the risk of multiple WMSDs (all P<0.05). Workers with regular/frequently work shifts had a lower risk of multi-site WMSDs than those with none/occasional work shifts (P<0.05). {L-End}Conclusion The prevalence of multi-site WMSDs among workers in the chemical pharmaceutical industry is relatively high. The influencing factors are individual factors, unreasonable work organization and poor ergonomics factors.

Objective:To explore the effect of combined therapy of traditional Chinese medicine on prevention of chemotherapy-related anemia in malignant tumors.Methods:Seventy-nine patients with malignant tumors diagnosed in Zibo Hospital of Traditional Chinese Medicine from January 2019 to January 2021 were selected, and the patients were divided into experimental group (40 cases) and control group (39 cases) according to the random number table method. The control group received chemotherapy and the experimental group received chemotherapy and combined therapy of traditional Chinese medicine (Wuhong Tang combined with moxibustion). The hemoglobin (Hb) level, Karnofsky score and adverse effects were recorded before and on days 7, 14 and 21 after chemotherapy in the two groups.Results:The Hb level in the experimental group was higher than that in the control group [(117±28) g/L vs. (100±31) g/L] on day 21 after chemotherapy, and the difference was statistically significant ( t = -3.08, P = 0.030). The total effective rate of the experimental group was higher than that of the control group [85% (34/40) vs. 66.7% (26/39)], but the difference was not statistically significant ( χ2 = 4.96, P = 0.084). Karnofsky scores were (77±9) points and (77±12) points before and on day 21 after treatment in the experimental group, with no statistical difference ( t = -0.50, P = 0.623); Karnofsky scores were (78±10) points and (67±9) points in the control group, with statistical difference ( t = 8.32, P < 0.001). There was no statistical difference in Karnofsky score before treatment between the two groups ( t = 1.85, P = 0.068), but the experimental group was higher than the control group on day 21 after treatment ( t = 4.88, P < 0.001). The difference in the incidence of nausea and vomiting between the two groups was not statistically significant ( P > 0.05), and no chemotherapy-related hepatic, renal or cardiac adverse reactions were observed in either group. Conclusions:Combined therapy of traditional Chinese medicine could effectively prevent chemotherapy-related anemia and improve the quality of life of patients.

Objective To study the feasibility of clinical application of an individualized customized material. Methods Five batches of individualized customized materials were randomly selected, from which 10 cm × 11 cm samples were intercepted for experimental analysis. Among them, 10 cm × 10 cm materials were selected to perform dosimetric analysis and HU change analysis before and after irradiation with a radiotherapy dose for breast cancer of 50 Gy as the irradiation basis. The center Point 1 on the lower surface of the individualized material and the center Point 2 of the solid water volume were selected for dosimetric analysis before and after the sample is irradiated. After reaching a sufficient amount of irradiation, the 1 cm × 10 cm materials intercepted in the center position and the remaining 1 cm × 10 cm materials after the first sampling were sent to the material science laboratory for analysis of physical properties of density, viscosity, hardness, and tear strength. Results In the comparative analysis of HU values before and after exposure, after receiving 50 Gy dose irradiation, the difference rate of HU value was 5.252%, which was close to the expected 5% difference rate in clinical medicine. In the dosimetric analysis of Point 1 and Point 2, the dose in the irradiated samples was significantly higher than that in the unirradiated samples; the dose in Point 1 increased by 3.742%, and the dose in Point 2 increased by 2.039%. Before and after irradiation, except for the physical density which showed a significant difference, there was no significant difference in viscosity, hardness, and tear strength. Conclusion The individualized customized material can meet the requirements of routine clinical medicine.

There is an urgent need to elucidate the pathogenesis of myocardial ischemia (MI) and potential drug treatments.Here,the anti-MI mechanism and material basis of Ginkgo biloba L.extract (GBE) were studied from the perspective of energy metabolism flux regulation.Metabolic flux analysis (MFA) was performed to investigate energy metabolism flux disorder and the regulatory nodes of GBE components in isoproterenol (ISO)-induced ischemia-like cardiomyocytes.It showed that[U-13C]glucose derived m+2 isotopologues from the upstream tricarboxylic acid (TCA) cycle metabolites were markedly accu-mulated in ISO-injured cardiomyocytes,but the opposite was seen for the downstream metabolites,while their total cellular concentrations were increased.This indicates a blockage of carbon flow from glycolysis and enhanced anaplerosis from other carbon sources.A Seahorse test was used to screen for GBE components with regulatory effects on mitochondrial aerobic respiratory dysfunction.It showed that bilobalide protected against impaired mitochondrial aerobic respiration.MFA also showed that bilobalide significantly modulated the TCA cycle flux,reduced abnormal metabolite accumulation,and balanced the demand of different carbon sources.Western blotting and PCR analysis showed that bilobalide decreased the enhanced expression of key metabolic enzymes in injured cells.Bilobalide's efficacy was verified by in vivo experiments in rats.This is the first report to show that bilobalide,the active ingredient of GBE,protects against MI by rescuing impaired TCA cycle flux.This provides a new mechanism and potential drug treatment for MI.It also shows the potential of MFA/Seahorse combi-nation as a powerful strategy for pharmacological research on herbal medicine.
