By consulting ancient and modern literature， this article systematically reviews and verifies the historical evolution of the herbal medicine known as Baijiang across various dimensions， including name， origin， scientific name verification， medicinal parts， production area， quality， harvesting and processing， as well as its nature， taste， and therapeutic effects， in order to provide a reference for the development and utilization of famous classical formulas containing Patriniae Herba. Patriniae Herba has a long history of use. It derives its name from the distinctive musty odor of its roots， which resembles spoiled soy sauce. However， due to its alias Kucai， there has been much confusion with other plants. Since the Ming dynasty， various plants have been used interchangeably as Baijiang. Herbal textual research showed that Patriniae Herba was first recorded in Shennong Bencaojing， and throughout history， Baijiang has been recognized as its standard name， though it has also been known by alternative names such as Luchang， Lujiang， and Suanyi. The main sources used throughout the ages were Patrinia scabiosaefolia or P. villosa， which is consistent with the 1977 edition of the Pharmacopoeia of the People's Republic of China. However， while the roots were traditionally used medicinally， the whole plant is now more commonly used in modern practice. In addition， the whole plants of Thlaspi arvense from the Cruciferae family and Sonchus brachyotus from the Compositae family are commonly used as regional substitutes for Baijiang. According to ancient records， Patriniae Herba was primarily found in Jiangxia（present-day eastern Hubei province） and Jiangdong（the region south of the lower reaches of the Yangtze River）， but modern literature shows that it is distributed throughout the country without a distinct geographical origin. In ancient times， the roots were harvested in August and sun-dried， today， the whole plant is typically dug up in summer or autumn and sun-dried. In recent times， the quality has been summarized as being best when the roots are long， the leaves are abundant and green， and the aroma is strong. Regarding the processing， ancient methods often involved baking（drying over fire）， while modern methods typically involve removing impurities， washing， and then cutting and drying the segments. The effects of Patriniae Herba are to clear heat and detoxify， eliminate blood stasis and drain pus. During the Han and Northern and Southern dynasties， it was used to treat skin diseases caused by heat， abscesses， postpartum diseases， and rheumatism， during the Five dynasties period， its therapeutic applications expanded to include diseases of the five senses， and by the modern era， conditions such as neurasthenia and insomnia were added. Regarding its properties and taste， it was recorded as bitter and neutral during the Han dynasty. By the Tang dynasty， it was slightly cold， with a taste of acrid and bitter. During the Yuan and Ming dynasties， it was mostly slightly cold and neutral， with a bitter and salty taste. In the Qing dynasty and modern times， it was mostly bitter and neutral， and in contemporary times， it has evolved to a taste of acrid， bitter， and cool. Based on the results of this study， it is recommended that when developing and utilizing famous classical formulas containing Patriniae Herba， one should select the entire herb of the historically mainstream sources， P. scabiosaefolia or P. villosa from the Valerianaceae family， and choose the processing method according to the prescription requirements. It is recommended to use raw products without specific requirements.

ObjectiveHepatocellular carcinoma (HCC) represents 90% of all primary liver cancers. The main risk factors associated with HCC include viral hepatitis (B and/or C), alcohol abuse, and metabolic dysfunction-associated steatotic liver disease (MASLD), which progressively advance to liver fibrosis, cirrhosis, and ultimately evolve into HCC. Surgical resection represents the most effective treatment for HCC, while recent advances in immunotherapy, including immune checkpoint inhibitors and adoptive cell therapies, have provided improved treatment prospects for patients with unresectable HCC. However, the complex metabolic heterogeneity of HCC limits the therapeutic efficacy. Metabolic intermediates acyl-CoA not only provide energy and substrates for numerous biochemical reactions but also serve as donors for protein lysine acylation, a major class of post-translational modification (PTM). Therefore, a deeper understanding of the molecular mechanisms underlying protein lysine acylation and hepatocarcinogenesis is urgently needed. MethodsThe levels of protein lysine acylation and silence information regulator 5 (SIRT5) expression levels in clinical HCC samples were analyzed by Western blot. Quantitative malonylome and succinylome of HCC samples were analyzed by antibody-based affinity enrichment coupled with tandem mass spectrometry. The proliferation of HCC cells was analyzed with Cell Counting Kit-8 (CCK-8) assays, the apoptosis was quantified by Annexin V-FITC/propidium iodide (PI) staining coupled with flow cytometry, and the ability of cells to migrate was assayed by Transwell assays. The enzymatic activity of glutathione S-transferase Mu 1 (GSTM1) was quantified. Transgenic mice with hepatic overexpression of SIRT5 were constructed using CRISPR-Cas9, and primary hepatocarcinogenesis was induced by administration of diethylnitrosamine. ResultsWestern blot analysis indicated that the expression level of SIRT5 was elevated in clinical samples from HCC patients, and the levels of lysine malonylation, glutarylation, and succinylation were significantly reduced in HCC tissues. Knockout of SIRT5 in MHCC-97H and MHCC-97L hepatoma cells suppressed cell proliferation, and increased the percentage of apoptotic cells significantly. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses of the differentially malonylome and succinylome of HCC samples revealed significant enrichment in two major classes of biological processes: core energy metabolism (e.g., glycolysis/gluconeogenesis, tricarboxylic acid metabolic process, fatty acid beta oxidation) and detoxification and oxidative stress response (e.g., response to toxic substance, chemical carcinogenesis, reactive oxygen species (ROS)). SIRT5 removes malonylation from lysine residues in GSTM1 and restores its detoxification activity, which is crucial for the survival of hepatocytes under stressed conditions. More importantly, in vivo experiment indicated that hepatic-specific overexpression of SIRT5 in mice accelerated diethylnitrosamine-induced liver fibrosis and hepatocarcinogenesis, indicating the critical role of SIRT5 in HCC progression. ConclusionThis study highlights the previously unrecognized SIRT5-GSTM1 axis as a key regulator in hepatocarcinogenesis, and suggests a potential target for the treatment of patients with HCC.

Objective This study reports on the obligatory parasitism of water mites Arrenurus sp. on Anopheles messeae at the Manzhouli Port, Inner Mongolia, China. Methods Duing July 2024, a survey on the mosquito diversity was conducted at the Manzhouli Port. Captured mosquitoes and their ectoparasites were identified to species level. Results A total of 1840 adult mosquitoes were collected, representing species from three genera: Culex(Cx. modestus, Cx. pipiens pallens), Aedes(Ae. dorsalis, Ae. flavidorsalis, Ae. flavescens), and Anopheles (An. messeae). Among all the mosqutioes specimens,3 out of 150 captured An. messeae were found to carry ectoparasitic mites, with number of 2,4,27 mites separately. Morphological and molecular identification reached the same result as water mites(Hydrachnidiae, Hydracrina). COI gene sequence showed 94% similarity with the closest species Arrenurus truncatellus. Conlusions Literature review suggests water mites are host-specific parasitism of mosquito species and herein with the first record of Arrenurus sp. parasiting on An. Messeae in the most high-latitude region globally.

PURPOSE: To judge the injury mode and injury severity of the real human body through the measured values of anthropomorphic test devices (ATD) injury indices, the mapping relationship of lumbar injury between ATD and human body model (HBM) was explored. METHODS: Through the ATD model and HBM simulation, the mapping relationship of lumbar injury between the 2 subjects was explored. The sled environment consisted of a semi-rigid seat with an adjustable seatback angle and a 3-point seat belt system with a seatback-mounted D-ring. Three seatback recline states of 25°, 45°, and 65° were designed, and the seat pan angle was maintained at 15°. A 23 g, 47 km/h pulse was used. The validity of the finite element model of the sled was verified by the comparison of ATD simulation and test results. ATD model was the test device for human occupant restraint for autonomous vehicles (THOR-AV) dummy model and HBM was the total human model for safety (THUMS) v6.1. The posture of the 2 models was adjusted to adapt to the 3 seat states. The lumbar response of THOR-AV and the mechanical and biomechanical data on L1 - L5 vertebrae of THUMS were output, and the response relationship between THOR-AV and THUMS was descriptive statistically analyzed. RESULTS: Both THOR-AV and THUMS were submarined in the 65° seatback angle case. With the change of seatback angle, the lumbar spine axial compression force (F_z) of THOR-AV and THUMS changed in the similar trend. The maximum F_z ratio of THOR-AV to THUMS at 25° and 45° seatback angle cases were 1.6 and 1.7. The flexion moment (M_y) and the time when the maximum M_y occurred in the 2 subjects were very different. In particular, the form of moment experienced by the L1 - L5 vertebrae of THUMS also changed. The changing trend of M_y measured by THOR-AV over time can reflect the changing trend of maximum stress of L1 and L2 of THUMS. CONCLUSION The F_z of ATD and HBM presents a certain proportional relationship, and there is a mapping relationship between the 2 subjects on F_z. The mapping function can be further clarified by applying more pulses and adopting more seatback angles. It is difficult to map M_y directly because they are very different in ATD and HBM. The M_y of ATD and stress of HBM lumbar showed a similar change trend over time, and there may be a hidden mapping relationship.

In this work,a fluorescent probe PIN was synthesized using indole-3-carbohydrazide and pyrenecarboxaldehyde as raw materials.PIN showed weak fluorescence emission in aqueous solution with acetonitrile volume fraction of 70％.However,when Cu2+was added to this aqueous solution of PIN,a new fluorescence emission peak appeared at 495 nm,and the intensity of this peak gradually increased with the increase of concentration of Cu2+,and also caused a significant change in the fluorescence color of the solution.In contrast,the addition of 15 kinds of other common metal ions did not cause such change.The detection limit of PIN for Cu2+was 78.7 nmol/L,which was much lower than the maximum permitting level of Cu2+in drinking water in hygienic standard for drinking water in China.Therefore,PIN was a highly selective and sensitive fluorescence-enhanced probe for Cu2+.Meanwhile,the addition of Cu2+could also cause a new absorption peak at 440 nm in the ultraviolet-visible absorption spectrum of the aqueous solution of PIN,and meanwhile the colorless PIN solution changed into yellow,exhibiting the performance of PIN as a colorimetric probe for Cu2+.By fitting with the Levenberg-Marquardt algorithm equation,the binding ratio of PIN to Cu2+was 2:1,and the binding constant was 3.42×1012 L2/mol2.In addition,the binding mode of PIN with Cu2+was explored by using proton nuclear magnetic resonance(1H NMR)titration experiments and density functional theory simulations.The results showed that the addition of Cu2+could cause the aggregation of PIN molecules to form excimers,thus showing highly selective recognition.Finally,PIN was made into a simple test strip,which could achieve rapid and convenient fluorescence detection of Cu2+in actual water samples.

Objective:To investigate the effects of exosomes secreted by bone marrow mesenchymal stem cells (BMSCs) during osteogenic differentiation on the polarization of Raw264.7 macrophages and to elucidate the underlying mechanisms.Methods:PBS, uninduced BMSCs conditioned medium (CM), and osteogenic induction BMSCs CM for 7 d, 14 d, and 21 d were respectively added to Raw264.7 macrophages. After 48 h of treatment, Western blotting was used to detect and compare the expression of M1 markers of macrophages [inducible nitric oxide synthase (iNOS) and CD86] and M2 markers of macrophages [arginase-1 (ARG-1) and CD163] in each group. In addition, Raw264.7 macrophages were divided into three groups: the PBS group (only PBS added), the BMSCs-exo group (exosomes derived from uninduced BMSCs were added), and 7D-BMSCs-exo (exosomes derived from BMSCs were added after 7 days of osteogenic induction). The absorbance values of Raw264.7 cells in each group at 24 h, 48 h and 72 h were detected by an enzyme-linked immunosorbent assay (ELISA) reader. Western blotting was performed to assess changes of M1 or M2 marker proteins in Raw264.7 macrophages treated by exosome. The supernatants of the three groups of Raw264.7 macrophages were then co-cultured with BMSCs. Alizarin Red staining was used to quantify the formation of mineralized nodules, and alkaline phosphatase (ALP) staining was used to evaluate the osteogenic activity, and the expression levels of osteogenesis-related proteins Runx2, ALP, osteopontin (OPN), and osteocalcin (OCN) were detected. The migration ability of endothelial progenitor cells (EPCs) was detected by scratch assay for migration distance, and the angiogenesis ability was detected by in vitro tube formation assay for the number of vascular rings formed. The expressions of vascular endothelial growth factor (VEGF)-A and platelet-derived growth factor (PDGF) were detected by Western blot. The activation of the MAPK signaling pathway was evaluated by measuring phosphorylated and total P38 and ERK1/2 levels.Results:Western blot analysis showed that CM from BMSCs after 7 days of osteogenic induction (7D-BMSCs-CM) induced the strongest M2 polarization in macrophages. Compared with the PBS group, 7D-BMSCs-CM induced the most significant polarization of Raw264.7 macrophages to the M2 type, and increased ARG-1 and CD163 expression to 1.36±0.09 and 1.69±0.09, respectively ( P<0.05), while decreasing iNOS and CD86 to 0.21±0.03 and 0.29±0.03 ( P<0.05). The absorbance values of macrophages in the 7D-BMSCs-exo group were significantly higher than those in the PBS group at 24 h, 48 h, and 72 h ( P<0.05). Compared with BMSCs-exo group, 7D-BMSCs-exo upregulated the expressions of CD163 and ARG-1 while inhibited the expressions of iNOS and CD86 ( P<0.05). Alizarin red staining showed enhanced mineral deposition and a higher degree of mineralization in the 7D-BMSCs-exo group, the staining intensity of ALP also increased simultaneously, the Western-blot results showed that the protein expressions of Runx2, ALP, OPN and OCN were respectively higher than those in the PBS group ( P<0.05). The results of the scratch assay showed that the relative migration distance of EPCs cells in the 7D-BMSCS-exo group at 24 h reached 2.30±0.05 μm, which was higher than that in the PBS group 1.10±0.02 μm ( P<0.05). The Tube formation experiment showed that the number of vascular rings in the EPCs group was higher than that in the PBS group (30.3±2.5 and 15.0±1.0, P<0.05), and the protein expressions of VEGF-A and PDGF were upregulated. Furthermore, the levels of phosphorylated P38 and ERK1/2 were significantly reduced in the 7D-BMSCs-exo group 0.40±0.06 and 0.25±0.06 compared with the PBS group ( P<0.05). Conclusions:Exosomes secreted by BMSCs during osteogenic differentiation promote the M2 polarization of Raw264.7 macrophages, with the most pronounced effect observed at the 7th day. M2-polarized macrophages, in turn, enhance the osteogenic differentiation of BMSCs and the angiogenic capacity of EPCs. These processes are closely associated with the suppression of the MAPK signaling pathway.

Objective:To investigate the drug resistance of newly diagnosed HIV-1 infected patients in Shanghai and to provide reference value for clinical antiretroviral therapy (ART).Methods:The peripheral venous blood plasma of 196 newly diagnosed HIV-1 infected patients screened according to the inclusion and exclusion criteria at the Shanghai Public Health Clinical Center from April to June 2023 was collected, HIV-1 RNA was extracted, the pol region was amplified by reverse transcription-polymerase chain reaction (RT-PCR) for sequencing, the mutation sites and ART drug resistance were analyzed.Results:The plasma of 196 newly diagnosed HIV-1 infected patients was amplified successfully in 162 cases (amplification success rate was 82.65%). The subtypes consisted of CRF07_BC(51.23%), CRF01_AE (27.78%), and others (6.79%), CRF55_01B (5.56%), B (3.70%), CRF01_AE/B (3.70%) and CRF08_BC (1.23%). The overall transmitted drug resistance rate was 7.41%, the protease inhibitors (PIs), non-nucleoside/nucleotide reverse transcriptase inhibitors (NNRTIs), nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), integrase inhibitors (INSTIs) resistance rates were 3.09%, 3.70%, 0.00% and 0.62%, respectively. The proportion of NNRTIs-related mutation sites in B (66.67%) and CRF55_01B (88.89%) was higher than that in CRF07_BC (13.25%); the proportion of NNRTIs-related mutation sites in CRF55_01B (88.89%) was higher than that in CRF01_AE (22.22%) and other subtypes (18.18%), the difference was statistically significant (all P<0.05). Multivariate logistic regression analysis showed that the probability of PIs-related mutation sites in CRF01_AE/B was 21.71 times that of CRF07_BC[odds ratio ( OR)=21.71, 95% confidence interval ( CI): 3.36-140.27, P=0.001]. Conclusions:The transmitted drug resistance among newly diagnosed HIV-1 infected patients in Shanghai is at the moderate epidemic level, mainly NNRTIs and PIs-related drug resistance, and the INSTIs resistance rate is low, the use of INSTIs in ART regimens should be considered.

Objective:To explore the clinical efficacy of the posterior to anterior malleolar extended lateral approach (PAMELA) in the treatment of quadrimalleolar fractures.Methods:A retrospective study was conducted to analyze the clinical data of 12 patients with quadrimalleolar fracture who had been admitted to Foot and Ankle Surgery Department, Henan Luoyang Orthopaedic & Traumatological Hospital from June 2022 to June 2023. There were 5 males and 7 females, with an age of (37.3±12.2) years and a duration from injury to surgery of (8.8±3.5) d. Open reduction and internal fixation of displaced Chaput tubercle fractures, lateral and posterior malleolar fractures were conducted through the PAMELA for all patients. The incision exposure, operation time, intraoperative bleeding, and incision healing were noted. Postoperatively, the fracture reduction was evaluated using the Burwell-Charnley criteria. The clinical efficacy was evaluated at the final follow-up using the ankle-hindfoot score of American Orthopaedic Foot & Ankle Society (AOFAS), visual analogue scale (VAS), and range of motion (ROM) of the ankle joint.Results:Good exposure of the Chaput tubercle, anterolateral tibiotalar joint, and lateral and posterior malleoli was achieved during surgery in all patients. The follow-up time for the 12 patients was (14.3±1.8) months, the operation time (152.5±26.0) minutes, and the intraoperative bleeding (137.5±44.1) mL. All incisions healed at the first stage postoperatively without any complications. According to the Burwell-Charnley criteria, anatomic reduction was achieved in all patients. CT scans showed good reduction of the distal tibiofibular syndesmosis. At the final follow-up, their AOFAS score was (94.1±8.3) points, VAS 0 (0, 1) point, and ankle joint ROM 17.5°±9.0° for dorsiflexion and 35.2°±9.6° for plantarflexion.Conclusions:In the treatment of quadrimalleolar fractures, because the PAMELA can lead to good exposure of the anterolateral ankle joint, distal tibiofibular syndesmosis, and lateral and posterior malleolar fractures, it results in a high rate of anatomic reduction of the fractures, safe incisions and limited soft tissue complications. Therefore, it is a safe, simple, and effective surgical approach.
