With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

UPLC-Q-TOF-MS combined with network pharmacology and experimental verification was used to explore the mechanism of acupoint sticking therapy(AST) in the intervention of bronchial asthma(BA). The chemical components of Sinapis Semen, Cory-dalis Rhizoma, Kansui Radix, Asari Radix et Rhizoma, and Zingiberis Rhizoma Recens were retrieved from TCMSP as self-built database. The active components in AST drugs were analyzed by UPLC-Q-TOF-MS, and the targets were screened out in TCMSP and Swiss-TargetPrediction. Targets of BA were collected from GeneCards, and the intersection of active components and targets was obtained by Venny 2.1.0. The potential targets were imported into STRING and DAVID for PPI, GO, and KEGG analyses. The asthma model induced by house dust mite(HDM) was established in mice. The mechanism of AST on asthmatic mice was explored by pulmonary function, Western blot, and flow cytometry. The results indicated that 54 active components were obtained by UPLC-Q-TOF-MS and 162 potential targets were obtained from the intersection. The first 53 targets were selected as key targets. PPI, GO, and KEGG analyses showed that AST presumedly acted on SRC, PIK3 CA, and other targets through active components such as sinoacutine, sinapic acid, dihydrocapsaicin, and 6-gingerol and regulated PI3 K-AKT, ErbB, chemokine, sphingolipid, and other signaling pathways to intervene in the pathological mechanism of BA. AST can improve lung function, down-regulate the expression of PI3 K and p-AKT proteins in lung tissues, enhance the expression of PETN protein, and reduce the level of type Ⅱ innate immune cells(ILC2 s) in lung tissues of asthmatic mice. In conclusion, AST may inhibit ILC2 s by down-regulating the PI3 K-AKT pathway to relieve asthmatic airway inflammation and reduce airway hyperresponsiveness.

OBJECTIVES: To examine the serum levels of degraded monosaccharides in children with Henoch-Schönlein purpura (HSP) and to study the clinical significance of degraded monosaccharides in HSP. METHODS: A prospective analysis was performed on 132 children who were diagnosed with HSP from September 2019 to January 2022, and 132 healthy children were enrolled as the control group. High-performance liquid chromatography was used to determine the content of degraded monosaccharides in serum in both groups. The receiver operating characteristic (ROC) curve was used to evaluate the efficiency of degraded monosaccharides for the diagnosis of HSP. RESULTS: Compared with the control group, the HSP group had significantly higher serum levels of mannose, glucosamine, aminogalactose, and galactose (P<0.001). The four degraded monosaccharides had an area under the ROC curve of 0.919, 0.913, 0.832, and 0.932 respectively for the diagnosis of HSP (P<0.05). CONCLUSIONS Children with HSP have higher serum levels of mannose, glucosamine, aminogalactose, and galactose than the healthy population. The levels of degraded monosaccharides may have an important value for the diagnosis of HSP.

Objective ： To study the effect of temperature and light intensity on photosynthetic fluorescence parameters, volatile oil content, and growth of Atractylodes lancea and provide reference for the rational selection of cultivation environment for A. lancea. MethodWe determined the photosynthetic indexes (such as net photosynthetic rate, water use efficiency, and carboxylation rate), light response curve, CO₂ response curve, fluorescence parameters, and the content of four volatile oils in A. lancea under two temperature treatments (32 °C and 22 °C) and two light treatments (full light and shade). ResultThe net photosynthetic rate and water use efficiency of A. lancea under high temperature + strong light were significantly higher than those under high temperature + weak light and low temperature + strong light. The ability of A. lancea to use weak light at low temperature was the strongest, while the utilization rate of weak light under strong light significantly reduced. The photosynthetic rate of A. lancea at low temperature was more susceptible to light intensity and CO₂ concentration than that at high temperature. The maximum photosynthetic rate and apparent quantum efficiency under weak light were significantly higher than those under strong light. The photoreaction efficiency at high temperature was higher than that at low temperature. The total amount of volatile oil in A. lancea treated with high temperature + weak light was the highest, reaching 4.582%. Compared with high temperature + strong light, high temperature + weak light significantly increased the content of hinesol and β-eudesmol in A. lancea by 91.7% and 35.7%, respectively, and low temperature + strong light significantly increased the content of hinesol by 87.5%. The content of β-eudesmol in low temperature + weak light treatment was significantly lower than that in high temperature + weak light treatment. ConclusionTThe growth of A. lancea was affected by the interaction between temperature and light. The light and temperature conditions required for the accumulation of volatile oil were not consistent with those suitable for the growth and development of A. lancea. A. lancea responded to the changes of light and temperature conditions by regulating the synthesis and accumulation of volatile oil.

Long non-coding RNA SLC25A25-AS1 has a tumor inhibition effect in the development of colorectal cancer. However‚ the mechanism of SLC25A25-AS1 in cervical cancer needs further study. We studied the abnormal expression of SLC25A25-AS1 in the serum of the patients with cervical cancer and the patients with cervical intraepithelial neoplasia (CIN) and explored the mechanism of SLC25A25-AS1 in the development of cervical cancer. The expression levels of SLC25A25-AS1 in the serum of normal controls‚ patients with cervical cancer‚ and patients with CIN were detected by RT-qPCR. The important role of SLC25A25-AS1 in HeLa cells was analyzed in vitro and in vivo experiments. Compared with the normal group‚ the expression level of serum SLC25A25-AS1 was decreased in patients with cervical cancer. In vitro‚ overexpression of SLC25A25-AS1 inhibited cell proliferation‚ migration‚ and invasion of HeLa cells. Tumor formation in nude mice assay showed that the subcutaneous tumor weight and volume of nude mice injected with SLC25A25-AS1-overexpressed HeLa cells were significantly smaller than that of nude mice injected with control cells (P<0. 05). SLC25A25-AS1 may play an important role in the development of cervical cancer and may serve as a new therapeutic target for cervical cancer.

Rhizosphere bacteria play a vital role in plant nutrition absorption,growth and disease resistance. In this study,high-throughput sequencing technology was used to analyze the rhizosphere bacterial communities of Salvia miltiorrhiza and S. miltiorrhiza f. alba. Moreover,the function of dominant rhizosphere bacterial communities was analyzed. We found that Sphingobacteriales,Sphingomonadales and Nitrosomonadaceae were both dominant and specific bacteria in the rhizosphere of S. miltiorrhiza. The main functions of dominant rhizosphere bacteria communities in both species include promoting transformation of soil nutrients,improving plant immunity and ability of stress tolerance. This study was the first to compare rhizobacterial communities structure and function of S. miltiorrhiza and S. miltiorrhiza f. alba,which provided a new theoretical reference for studing the rhizosphere mechanism of healthy S. miltiorrhiza planting in the future.

Objective To evaluate the impact of different rating instruments used by raters with different seniority in OSCEs. Methods Surgical interns were randomly divided into two groups to undertake a nine－station surgical OSCEs. Raters with different seniority were also divided into two groups with four senior raters and four junior raters in one group. OSCE results were compared. Results There was no statistical significance when comparing results from different raters using checklist rating instrument. Results from different raters using global rating scale instrument were significantly different. Correlations between raters using checklist and global rating scale instruments showed statistical significance in 81.3% of stations. Conclusion Checklist rating instrument showed high capability of repeating the results. Therefore, it is recommended to apply checklist as many as possible in OSCE exams with mixed rater seniorities. Research on design of rating instruments are to be investigated to insure the effectiveness as well as the credibility of the rating system.

The soil fertility has great impacts on the yielding of Chinese medicinal materials, as well as the generation of major components. The practices showed that soil fertility has been decayed with the growth of cultivation years,which is leading to adverse effect on quality and quantity of Chinese medicinal materials. However, there was a lack of domestic unified standard for assessment of soil fertility of Chinese medicinal material cultivation, which has seriously limited the soil management and quality control. In this text, we reviewed the progress on research of soil fertility evaluation, built the soil fertility evaluation index including soil texture,soil bulk density,soil organic matter,soil acidity and alkalinity,soil available nitrogen,soil available phosphorus, soil available potassium,soil animals and soil microorganisms. It would provide the direction and thought for standard-settin on soil fertility evaluation of Chinese medicinal material cultivation.
