Pinelliae Rhizoma (PR), known as Banxia in Chinese, Hange in Japanese, and Banha in Korean, is a renowned herbal medicine in East Asia derived from the dry tuber of Pinellia ternata (Thunb.) Breit. (PT). It is extensively utilized in dispensing granules, classical prescriptions, and herbal formulas to treat various conditions, including cough, infection, phlegm, nausea, asthma, and inflammation. Despite numerous studies on PR and its classical prescriptions over recent decades, a comprehensive synthesis of available evidence regarding its multifunctional roles and therapeutic potential is lacking. This review aims to address this gap by examining emerging evidence from metabonomics, preclinical studies, and clinical trials, while exploring potential trends and prospects for future research. A systematic literature search was conducted across six electronic databases, including PubMed, Web of Science, Scopus, ScienceDirect, Wanfang, and China National Knowledge Infrastructure, to identify relevant articles on PR published until March 2023. PR contains 107 compounds with diverse pharmacological activities, including anti-inflammatory, immune regulatory, anti-viral, anti-cancer, anti-asthma, antitussive and expectorant, antioxidant, anti-obesity, anti-atherosclerosis, anti-microbial, emetic and anti-emetic, anti-convulsant and anti-epileptic, sedative and hypnotic, learning and memory enhancement, and anti-depressant effects. Metabonomic studies suggest that raw PR may exhibit cardiotoxicity and pregnancy toxicity while showing no apparent hepatorenal toxicity. However, limited pharmacokinetic investigations on PR constrain its clinical translation. Furthermore, clinical safety data on PR is scarce, with only four clinical trials assessing its positive effects in pediatric epilepsy, nausea and vomiting, soft tissue injury, and chronic sinus tract. This review aims to enhance understanding of PR and provide valuable information and recommendations for further research and development of herbal medicine.

Objective To study the efficacy of breathing training in the patients with chronic non-spe-cific low back pain (CNLBP).Methods The databases of Pubmed,Embase,Web of Science,Cochrane Librar-y,CNKI,China Biomedical Literature Database,Wanfang Database and VIP Database were searched for obtai-ning relevant trials of respiratory-related training for treating CNLBP.The retrieval time limit was from the database establishment to October 2022.The quality assessment was performed by using the Cochrane Manual for Systematic Reviews,and the data analysis was performed by using StataSE15.1 software.Results Nine-teen articles were finally obtained,involving in 1011 cases.The meta analysis showed that the visual analogue scale (VAS) score or pain numerical scale (NRS) score in the experiment group were lower than those in the control group (MD=-1.19,95％CI:-1.51 to-0.87,P<0.05),and the Oswestry dysfunction index (ODI) score was lower than that in the control group (MD=-0.64,95％CI:-0.91 to-0.38,P<0.05). For different types of the patients,the improvement effects of VAS score for different types of patients with CNLBP from high to low were in turn postpartum patients (MD=-1.89,95％CI:-2.51 to-1.27,P<0.05),athletes (MD=-1.46,95％CI:-1.79 to-1.13,P<0.05) and general population (MD=-1.01,95％CI:-1.40 to-0.61,P<0.05).Conclusion Thebreathing training has the improvement effect for pain,dysfunction,proprioception and posture control in various populations with CNLBP.

Objective To study the microanatomic structure of the subtemporal transtentorial approach to the lateral side of the brainstem,and to provide anatomical information that will assist clinicians to perform surgeries on the lateral,circumferential,and petroclival regions of the brainstem.Methods Anatomical investigations were conducted on 8 cadaveric head specimens(16 sides)using the infratemporal transtentorial approach.The heads were tilted to one side,with the zygomatic arch at its highest point.Then,a horseshoe incision was made above the auricle.The incision extended from the midpoint of the zygomatic arch to one third of the mesolateral length of the transverse sinus,with the flap turned towards the temporal part.After removing the bone,the arachnoid and the soft meninges were carefully stripped under the microscope.The exposure range of the surgical approach was observed and the positional relationships of relevant nerves and blood vessels in the approach were clarified.Important structures were photographed and the relevant parameters were measured.Results The upper edge of the zygomatic arch root could be used to accurately locate the base of the middle cranial fossa.The average distances of the star point to the apex of mastoid,the star point to the superior ridge of external auditory canal,the anterior angle of parietomastoid suture to the superior ridge of external auditory canal,and the anterior angle of parietomastoid suture to the star point of the 10 adult skull specimens were 47.23 mm,45.27 mm,26.16 mm,and 23.08 mm,respectively.The subtemporal approach could fully expose the area from as high as the posterior clinoid process to as low as the petrous ridge and the arcuate protuberance after cutting through the cerebellar tentorium.The approach makes it possible to handle lesions on the ventral or lateral sides of the middle clivus,the cistern ambiens,the midbrain,midbrain,and pons.In addition,the approach can significantly expand the exposure area of the upper part of the tentorium cerebelli through cheekbone excision and expand the exposure range of the lower part of the tentorium cerebelli through rock bone grinding technology.The total length of the trochlear nerve,distance of the trochlear nerve to the tentorial edge of cerebellum,length of its shape in the tentorial mezzanine,and its lower part of entering into the tentorium cerebelli to the petrosal ridge were(16.95±4.74)mm,(1.27±0.73)mm,(5.72±1.37)mm,and(4.51±0.39)mm,respectively.The cerebellar tentorium could be safely opened through the posterior clinoid process or arcuate protrusion for localization.The oculomotor nerve could serve as an anatomical landmark to locate the posterior cerebral artery and superior cerebellar artery.Conclusion Through microanatomic investigation,the exposure range and intraoperative difficulties of the infratemporal transtentorial approach can be clarified,which facilitates clinicians to accurately and safely plan surgical methods and reduce surgical complications.

Objective To explore the clinical significance of sortilin 1(SORT1)gene as a new diagnostic biomarker for pediatric sep-sis.Methods Three pediatric sepsis-related microarray datasets,including GSE13904,GSE26378,and GSE26440,were obtained from the gene expression omnibus(GEO)database to analyze the expression difference of SORT1 gene between normal and sepsis sam-ples.Then,65 clinical samples were used to validate the difference through qRT-PCR.The molecular mechanism and biological process associated with SORT1 gene were explored by the gene set enrichment analysis(GSEA).Results The expression levels of SORT1 gene in the sepsis samples of GSE13904,GSE26378,and GSE26440 datasets and clinical samples were higher than that in normal samples.Compared with commonly used inflammatory markers such as procalcitonin(PCT),C-reactive protein(CRP),white blood cell(WBC),and the percentage of neutrophils(Neu％),SORT1 gene showed better diagnostic ability for pediatric sepsis and the area under the receiver operating characteristic(ROC)curve(AUCROC)was 0.863.SORT1 gene may be involved in the occurrence and de-velopment of pediatric sepsis through the TNF-α/NF-κB signaling pathway.Conclusion SORT1 gene may have certain diagnostic val-ue for pediatric sepsis,which needs to be further confirmed in clinical practice.

Objective: To investigate the potential mechanism of Wendan decoction in obesity by screening target genes with promoter region methylation changes and constructing a multiple signaling pathways network based on promoter methylation. Methods: The methylation degree of Itgad, Col8a1, Adra2b, Jund, Rab2a, Wnt8b, Fzd9, B4galt7, Pik3cd, Creb1, Stard8, and Mmp1 in the abdominal adipose tissue of obese rats was determined using the Agena MassARRAY system. Western blot was performed to assess protein expression levels. Target genes were identified based on the methylation degree in the promoter region and protein expression. Enrichment analysis of signaling pathways was conducted to identify relevant target genes and obtain a multiple signaling pathway network associated with obesity. Core and terminal effector molecules in the pathway networks were selected as research targets for reverse transcription-polymerase chain reaction (RT-PCR) analysis. Results: Four genes (Adra2b, Creb1, Itgad, and Pik3cd) showed a degree of promoter methylation consistent with their respective protein expression levels. Among them, Adra2b, Creb1, and Pik3cd expression increased, while that of Itgad decreased. Enrichment analysis revealed that Creb1 and Pik3cd were involved in 6 signaling pathways related to obesity: tumor necrosis factor (TNF) signaling pathway, growth hormone synthesis/secretion and action, adenosine 5′-monophosphate-activated protein kinase (AMPK) signaling pathway, relaxin signaling pathway, cyclic nucleotide (cAMP) signaling pathway, and phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway. Subsequently, a multiple signaling pathways network was constructed based on promoter methylation. Key molecules including protein kinase B (AKT), mechanistic target of rapamycin complex 1 (mTORC1), and unc-51 like autophagy activating kinase 1 (ULK1), as well as terminal effector molecules interleukin-1β (IL-1β), interleukin-6 (IL-6), and chemokine (C-X-C motif) ligand 2 (CXCL2) were selected as research targets. Wendan decoction decreased the expressions of AKT, mTORC1, IL-1β, IL-6, and CXCL2 while up-regulating ULK1 expression. Conclusion The mechanism of Wendan decoction in preventing obesity involves the regulation of multiple signaling pathways through the control of Creb1 and Pik3cd gene promoter methylation. However, the associated multi-path gene regulation mechanism in preventing obesity is complex. Thus, further exploration is needed to elucidate the role of methylation changes in this mechanism.

Objective:To evaluate the short-term and long-term efficacy of Heidelberg triangle dissection in surgical treatment for pancreatic head cancer.Methods:The clinicopathological data of 97 patients with pancreatic head cancer who underwent pancreaticoduodenectomy at Cangzhou Central Hospital from Jan 2017 to Jan 2020 were retrospectively analyzed. After propensity score matching, 33 patients were included into the Heidelberg group and 36 patients in the control group.Results:There were no significant difference between Heidelberg group and control group in preoperative general conditions and postoperative major complications, while there were more cases with safe surgical margin > 1 mm (81.8% vs. 58.3%, P=0.034) and a significantly higher total number of lymph node dissection (11.24±2.35 vs. 9.50±2.76, P=0.006). In the survival analysis, the cumulative recurrence rate at 12 months (0.182±0.067 vs. 0.444±0.083, P=0.023) and 18 months (0.424±0.086 vs. 0.667±0.079, P=0.024) were better off in the Heidelberg group, and the local recurrence rate in the Heidelberg group was significantly lower than that in the control group (15.3 % vs. 36.1 %, P=0.037). However, there was no statistical difference in the overall survival time between the two groups. Conclusion:Dissection of Heidelberg triangle in radical resection of pancreatic head cancer reduces tumor local recurrence ,while fails to provide survival benefit.

Objective:To investigate the effects of extracts of Rhizoma Sparganii and Rhizoma Curcumae on cartilage damage in osteoarthritis rats and NADPH oxidase 2 (NOX2)/reactive oxygen species (ROS)/nuclear factor-κB (NF-κB) signaling pathways. Methods:Rats (50 cases) were divided into the sham group, and model group, as well as the low, medium, and high dose groups of extracts of Rhizoma Sparganii and Rhizoma Curcumae, with 10 rats in each group. Except for sham group, the rat model of cartilage damage in knee osteoarthritis was established. On the second day after modeling, the rats in the low, medium, and high dose groups received intragastric extracts perfusion of Rhizoma Sparganii and Rhizoma Curcumae at the doses of 5, 10, and 20 g/kg respectively. The rats in the sham and model groups received intragastric equivalent 0.9% sodium chloride solution perfusion, once daily, for 20 days by continuous administration. The knee joint behavior, bone metabolism indicators, serum superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH) levels, inflammatory factors, NOX2, and NF-κB levels of each group were observed. Results:Compared with the model group, the behavioral abnormality scores, cartilage oligomeric matrix protein (COMP), MDA, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), NOX2, and NF-κB levels in the low, medium, and high dose groups were all gradually decreased (all P < 0.05), while proteoglycan, SOD, GSH, and interleukin-10 (IL-10) levels in the low, medium, and high dose groups were all gradually increased (all P < 0.05), and it was dose-dependent. Conclusions:Rhizoma Sparganii and Rhizoma Curcumae extracts can effectively improve cartilage damage in osteoarthritis rats, and it may be related to the inhibition of the NOX2/ROS/NF-κB signaling pathway.

Objective:To report single-center clinical experience with endovascular recanalization for non-acute symptomatic intracranial vertebral artery occlusion, to assess the feasibility and safety of endovascular recanalization and to propose the benefit group for selected patients.Methods:From January 2019 to December 2021, 92 patients with non-acute symptomatic intracranial vertebral artery occlusion who underwent endovascular recanalization were retrospectively analyzed. The patients were divided into three groups (low, medium and high-risk group) according to occlusion length, occlusion duration, occlusion nature, calcification of the occlusion segment, and occlusion angulation, and the indicators of patients in each group were analyzed, including the general baseline data of the patients, surgical status and follow-up results. The technical success and perioperative complication rates of low, medium and high-risk groups were calculated. Meanwhile, the differences between three groups were evaluated using the χ2 test for trend or ANOVA analysis. Results:The overall technical success rate of endovascular recanalization was 83.7% (77/92), and the perioperative complication rate was 10.9% (10/92). Among the 3 classification groups, the recanalization success rate from the low-risk group to the high-risk group was 100%, 93.3%, 27.8%( P=0.047), and gradually decreased; while the overall perioperative complication rate was 0, 10.0%, 38.9% ( P=0.001), and gradually increased; the proportion of 90-day mRS score 0-2 was 100%, 83.3%, 22.2% ( P=0.026), and progressively decreased; 77 patients with successful recanalization were followed up, the rate of restenosis/reocclusion was 0, 17.9%, 80.0%( P=0.001), and progressively increased. Patients in the low-and intermediate-risk groups performed well with endovascular recanalization. In 88 patients (4 patients lost to follow-up), a median clinical follow-up of 13 (7, 16) months, stroke or death beyond 30 days was 17.4% (16/92). Conclusions:Endovascular recanalization is safe and feasible for reasonably selected patients with non-acute symptomatic intracranial vertebral artery occlusion, especially in low-and medium-risk groups, and it also provides an alternative to conservative therapy for patients with non-acute symptomatic intracranial vertebral artery occlusion.
