Aromatherapy refers to the method of using the aromatic components of plants in appropriate forms to act on the entire body or a specific area to prevent and treat diseases. Essential oils used in aromatherapy are hydrophobic liquids containing volatile aromatic molecules， such as limonene， linalool， linalool acetate， geraniol， and citronellol. These chemicals have been extensively studied and shown to have a variety of functions， including reducing anxiety， relieving depression， promoting sleep， and providing pain relief. Terpenoids are a class of organic molecules with relatively low lipid solubility. After being inhaled， they can pass through the nasal mucosa for transfer or penetrate the skin and enter the bloodstream upon local application. Some of these substances also have the ability to cross the blood-brain barrier， thereby exerting effects on the central nervous system. Currently， the academic community generally agrees that products such as essential oils and aromatherapy from aromatic plants have certain health benefits. However， the process of extracting a single component from it and successfully developing it into a drug still faces many challenges. Its safety and efficacy still need to be further verified through more rigorous and systematic experiments. This article systematically elaborated on the efficacy of aromatic substances， including plant extracts and natural small molecule compounds， in antibacterial and antiviral fields and the regulation of nervous system activity. As a result， a deeper understanding of aromatherapy was achieved. At the same time， the potential of these aromatic substances for drug development was thoroughly explored， providing important references and insights for possible future drug research and application.

This study aims to establish a multiplex TaqMan fluorescence quantitative PCR(qPCR)assay for Pasteurella multocida(P.multocida).Specific primers and fluorescent labeling probes were designed based on the sequences of five podoplanar genes of P.multocida hyaC-hyaD,bcbD,dcbF,ecbJ,and fcbD in the NCBI database.We adjusted the annealing temperature by gradient setting,optimized the primer and probe concentrations by matrix method,constructed standard curves,and performed specificity,sensitivity and reproducibility tests,and finally established mul-tiplexed TaqMan qPCR assays for these five genes.The results showed that the established assay had a good linear relationship between the amplification curves.The sensitivity of this method was high,10-100 times higher than that of ordinary PCR;the specificity was strong,and there was no amplification curve in the DNA detection of eight pathogenic bacteria such as Bacillus,Proteus mirabilis,Staphylococcus aureus,and Rhizoctonia rad iodurans.This assay had a good linear rela-tionship,and the coefficients of variation for Ct values of the inter-and intra-group reproducibility tests were all less than 3％,and the detection rate of this assay was 11.25％higher than the con-ventional PCR assay through the detection of 90 clinical samples.The method established in this study is able to detect P.multocida rapidly and sensitively,which is important for its rapid clinical and laboratory diagnosis.

ObjectiveTo observe the effect of comprehensive intervention on the incidence of lactation galactostasis in communities from the perspective of preventive medicine， so as to prevent the occurrence of the mammary ducts obstruction disease. MethodsA total of 400 women in the early stage of pregnancy were selected from four communities. Those in two communities were set up as the intervention group. Comprehensive intervention for the prevention and treatment of mammary ducts obstruction disease during pregnancy and "Six-step recanalization manual therapy" practical guidance were conducted on the intervention group. The pregnant women from the other two communities were the control group， who received no intervention or guidance training. The two groups were followed up at 1 month， 3 months and 5 months postpartum， and the occurrence of mammary ducts obstruction disease was investigated and interventions were carried out. ResultsThe incidence of galactostasis in the intervention group was 26.0%， 10.6% and 5.1%， respectively at 1， 3 and 5 months after delivery， and the incidence of galactostasis in the control group was 38.0%， 22.2% and 8.3%， respectively. The incidence of galactostasis at 1 month and3 months after delivery was statistically different （P<0.05）， while the incidence of galactostasis 5 months after delivery was not statistically different （P>0.05）. The protection rates of comprehensive intervention on galactostasis were 31.58%， 52.25% and 38.55%， respectively. ConclusionPublicity and education work of prevention and control of the mammary ducts obstruction disease and "Six-step recanalization manual therapy" practical guidance can effectively reduce the occurrence of plugged mammary ducts， and therefore should be promoted.

Using chemoproteomic techniques, we first identified EIF2AK2, eEF1A1, PRDX3 and VPS4B as direct targets of berberine (BBR) for its synergistically anti-inflammatory effects. Of them, BBR has the strongest affinity with EIF2AK2 via two ionic bonds, and regulates several key inflammatory pathways through EIF2AK2, indicating the dominant role of EIF2AK2. Also, BBR could subtly inhibit the dimerization of EIF2AK2, rather than its enzyme activity, to selectively modulate its downstream pathways including JNK, NF-κB, AKT and NLRP3, with an advantage of good safety profile. In EIF2AK2 gene knockdown mice, the inhibitory IL-1β, IL-6, IL-18 and TNF-α secretion of BBR was obviously attenuated, confirming an EIF2AK2-dependent anti-inflammatory efficacy. The results highlight the BBR's network mechanism on anti-inflammatory effects in which EIF2AK2 is a key target, and inhibition of EIF2AK2 dimerization has a potential to be a therapeutic strategy against inflammation-related disorders.

Accurate classification of the acetabular injuries and appropriate treatment plan are great challenges for orthopedic surgeons because of the irregular anatomical structure of the acetabulum and aggregation of important vessels and nerves around it. Letournel-Judet classification system has been widely applied to classify acetabular fractures. However, there are several limitations, including incomplete inclusion of fracture types, difficulty in understanding and insufficient guidance for surgical treatment, etc. Serious complications such as traumatic arthritis are common due to wrong classification and diagnosis and improper selection of surgical strategy, which brings a heavy burden to the society and families. Three-column classification, based on anatomic characteristics, has advantages of containing more fracture types and being easy to understand, etc. To solve the problems existing in the diagnosis and treatment process based on Letournel-Judet classification, achieve accurate diagnosis and treatment of patients with acetabular fractures, and obtain satisfactory prognosis, the Orthopedic Trauma Emergency Center of Third Hospital of Hebei Medical University and the Trauma Orthopedic Branch of the Chinese Orthopedic Association organized experts from relevant fields to formulate the Expert consensus on the accurate diagnosis and treatment of acetabular fractures based on three-column classification ( version 2023) in terms of principles of evidence-based medicine. Based on the three-column classification, 15 recommendations were proposed, covering the diagnosis, treatment, complication prevention and management, etc, so as to provide reference for accurate diagnosis and treatment of acetabular fractures.

Objective:To investigate the prevalence of lymphocytic choriomeningitis virus (LCMV) and hantavirus (HV) specific antibodies among cross-border migrant workers for assessment of the risk of rodents-borne virus infection.Methods:From 2019 to 2020, a survey was conducted on cross border migrant workers engaged in outdoor activities, and serum samples were collected, LCMV specific IgG antibody was detected by an indirect ELISA and Western blot based on recombinant nucleoprotein, and indirect immunofluorescence assay (IFA) based on recombinant expressed glycoprotein. HV IgG antibody in serum was detected by a commercial indirect IgG ELISA kit and IFA based on hantavirus infected Vero cells.Results:A total of 139 cross-border workers, aged 25~57, were surveyed; 64% (89/139) had working experience in multiple countries, involving 26 countries, including 14 countries in Asia and 12 countries in Africa; 11.51% (16/139) of serum samples were tested positive for LCMV antibodies, and the positive samples were verified by Western blot and IFA. The antibody detection rate was slightly higher than the published infection rate from other similar studies. And, HV antibodies were detected from one serum sample (0.72%, 1/139) by ELISA and IFA. However, it was still uncertain when and where the viral infections were acquired.Conclusions:Through this serological cross-sectional preliminary analysis, the infection status and existing risks of LCMV and HV viruses among cross border migrant workers were revealed, which suggested the necessity of strengthening the prevention and control of rodents borne diseases in outdoor engineering sites.

Sialic acid binding Ig-like lectin 10 (Siglec10) is a member of innate immune checkpoints that inhibits the activation of immune cells through the interaction with its ligand CD24 on tumor cells. Here, by analyzing public databases containing 64 517 patients of 33 cancer types, we found that the expression of Siglec10 was altered in 18 types of cancers and was associated with the clinical outcomes of 11 cancer types. In particular, Siglec10 was upregulated in patients with kidney renal clear cell carcinoma (KIRC) and was inversely associated with the prognosis of the patients. In 131 KIRC patients of our settings, Siglec10 was elevated in the tumor tissues of 83 (63.4%) patients compared with that in their counterpart normal kidney tissues. Moreover, higher level of Siglec10 was associated with advanced disease (stages III and IV) and worse prognosis. Silencing of CD24 in KIRC cells significantly increased the number of Siglec10-expressing macrophages phagocytosing KIRC cells. In addition, luciferase activity assays suggested that Siglec10 was a potential target of the transcription factors c-FOS and GATA1, which were identified by data mining. These results demonstrate that Siglec10 may have important oncogenic functions in KIRC, and represents a novel target for the development of immunotherapies.

Objective     To share the clinical experience of video-assisted thoracoscopic surgery (VATS) anatomic basal segmentectomy by single-direction method. Methods     The clinical data of 352 patients who underwent VATS anatomic basal segmentectomy in West China Hospital between April 2015 and April 2021 were retrospectively reviewed, including 96 males and 256 females with a median age of 50 (range, 26-81) years. All basal segmentectomies were performed under thoracoscopy, through the interlobar fissure or inferior pulmonary ligament approach, and following the strategy of single-direction and the method of "stem-branch". Results    All patients underwent basal segmentectomy successfully (49 patients of uniportal procedure, 3 patients of biportal procedure and 300 patients of triportal procedure) without addition of incisions or conversion to thoracotomy and lobectomy. The median operation time was 118 (range, 45-340) min, median intraoperative blood loss was 20 (range, 5-500) mL, median drainage time was 2 (range, 1-22) d and median postoperative hospital stay was 4 (range, 2-24) d. The postoperative complications included pneumonia in 6 patients, prolonged drainage (air leakage duration>5 d or drainage duration>7 d) in 18 patients, cerebral infarction in 1 patient and other complications in 2 patients. All patients were treated well and discharged without main complaints. No perioperative death happened. Conclusion    VATS anatomic basal segmentectomy is feasible and safe. It can be performed in a simple manner following the strategy of single-direction.

Objective     To summarize the perioperative and long-term outcomes of ground-glass opacity (GGO) dominant early stage lung cancer patients treated by anatomic segmentectomy. Methods     We collected clinical data of 756 patients from Western China Lung Cancer Database, who underwent intentional anatomic segmentectomy [tumor size (T) ≤ 2 cm, GGO ≥ 50%] in the Department of Thoracic Surgery, West China Hospital, Sichuan University from 2009 to 2018. There were 233 males and 523 females at a median age of 53 (25-83) years including 290 (38.4%) patients of simple segmentectomy and 466 (61.6%) patients of complex segmentectomy. All patients were diagnosed as adenocarcinoma, including 338 (44.7%) patients of minimally invasive adenocarcinoma and 418 (55.3%) patients of invasive adenocarcinoma. Results     The median operative time was 115 (38-300) min, the median blood loss was 20 (5-800) mL, 58 (7.7%) patients had postoperative complications and the postoperative stay was 4 (2-24) days. The median follow-up period was 43.0 (30.1-167.9) months. Five-year overall survival rate was 99.5% [95%CI (98.8%, 100.0%)], 5-year recurrence-free survival rate was 98.8% [95%CI (97.5%, 100.0%)], and 5-year lung cancer-specific survival rate was 100.0%. Conclusion    Anatomic segmentectomy has favorable perioperative outcomes and excellent prognosis in GGO dominant early stage lung cancer patients.

Objective     To analyze the perioperative outcomes of uniportal thoracoscopic lobectomy compared with three-port thoracoscopic lobectomy. Methods     Data were extracted from the Western China Lung Cancer Database, a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University. Perioperative outcomes of the patients who underwent uniportal or three-port thoracoscopic lobectomy for lung cancer during January 2014 through April 2021 were analyzed by using propensity score matching. Altogether 5 817 lung cancer patients were enrolled who underwent thoracoscopic lobectomy (uniportal: 530 patients; three-port: 5 287 patients). After matching, 529 patients of uniportal and 1 583 patients of three-port were included. There were 529 patients with 320 males and 209 females at median age of 58 (51, 65) years in the uniportal group and 1 583 patients with 915 males and 668 females at median age of 58 (51, 65) years in the three-port group. Results     Uniportal thoracoscopic lobectomy was associated with less intraoperative blood loss (20 mL vs. 30 mL, P<0.001), longer operative time (115 min vs. 105 min, P<0.001) than three-port thoracoscopic lobectomy. No significant difference was found between the two groups regarding the number of lymph node dissected, rate of conversion to thoracotomy, incidence of postoperative complication, postoperative pain score within 3 postoperative days, length of hospital stay, or hospitalization expenses. Conclusion     Uniportal video-assisted thoracoscopic lobectomy is safe and effective, and the overall perioperative outcomes are comparable between uniportal and three-port strategies, although the two groups show differences in intraoperative blood loss.
