ObjectiveTo explore the quantity-quality transfer process of medicinal materials， decoction pieces and standard decoction of Haliotidis Concha（Haliotis discus hannai） by analyzing the physical phase and compositional changes， so as to provide references for the effective control of its quality. MethodsA total of 20 batches of Haliotidis Concha（H. discus hannai） from different habitats were collected and prepared into corresponding calcined products and standard decoction， and the content of CaCO₃ of the three samples were determined and the extract yield and transfer rate of CaCO₃ were calculated. The changes in elemental composition and their relative contents were investigated by X-ray fluorescence spectrometry（XRF）， X-ray diffraction（XRD） was used to study the changes in the phase compositions of the three samples and to establish their respective XRD specific chromatogram. Fourier transform infrared spectrometry（FTIR） was used to study the changes in the chemical composition and content changes of the three samples and to establish their respective FTIR specific chromatogram， while combining hierarchical cluster analysis（HCA）， principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） to find the common and differential characteristics， in order to explore the quantity-quality transfer relationship in the preparation process of standard decoction of Haliotidis Concha（H. discus hannai）. ResultsThe CaCO₃ contents of the 20 batches of medicinal materials， decoction pieces and standard decoction of Haliotidis Concha（H. discus hannai） were 93.87%-98.95%， 96.02%-99.97% and 38.29%-51.96%， respectively， and the extract yield of standard decoction was 1.71%-2.37%， and the CaCO₃ transfer rate of decoction pieces-standard decoction was 0.68%-1.27%. XRF results showed that the elemental species and their relative contents contained in Haliotidis Concha and its calcined products had a high degree of similarity， and although there was no obvious difference in the elemental species contained in decoction pieces and standard decoction， the difference in the relative contents was obvious， which was mainly reflected in the decrease of the relative content of element Ca and the increase of the relative content of element Na. XRD results showed that Haliotidis Concha mainly contained CaCO₃ of aragonite and calcite， while calcined Haliotidis Concha only contained CaCO₃ of calcite， and standard decoction mainly contained CaCO₃ of calcite and Na₂CO₃ of natrite. FTIR results showed that there were internal vibrations of O-H， C-H， C=O， HCO₃^- and CO₃^2- groups in Haliotidis Concha， while O-H， HCO₃^- and CO₃^2- groups existed in the calcined products and standard decoction. ConclusionThe changes of Haliotidis Concha and calcined Haliotidis Concha are mainly the increase of CaCO₃ content， the transformation of CaCO₃ aragonite crystal form to calcite crystal form and the absence of organic components after calcination， and the changes of calcined products and standard decoction are mainly the decrease of CaCO₃ content and the increase of Na₂CO₃ relative content. The method established in the study is applicable to the quality control of the shellfish medicines-decoction pieces- standard decoction， which provides a new idea for the study of quality control of dispensing granules of shellfish medicines.

Objective To construct N6-methyladenosine related long non-coding RNA(LncRNA)pairing model for renal cell carcinoma based on bioinformatics analysis of the cancer ganome atlas(TCGA)database and to explore its prognosis value.Methods Transcriptome data of RNA-sep for renal cell carcinoma and its related clinical information were downloaded from the TCGA database.Perl software was used to organize and separate LncRNA and messenger RNA(mRNA)from the transcriptome data.A total of 564 tissues from renal cell carcinoma cases and 72 normal tissues were obtained,and thus 540 renal cancer patients were eventually included.Random data table method was used to divide 540 patients with renal cancer into a training group(n=275)and a validation group(n=265)by caret.M6A related LncRNA pairing models were established based on the single factor and multivariate COX regression analysis.The risk assessment equation was obtained using the LASSO regression algorithm.The risk scores were calculated based on this equation,and the optimal critical point of the median risk value was applied to divide all patients into high-risk and low-risk groups.Kaplan-Meier survival analysis was used to make a survival curve for the differences between high and low risk groups in the overall sample.The gene ontology(GO)and Kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analyses were conducted using the Cluster Profiler software package.The relationship between N6-methyladenosine related LncRNA pairing model and immune cell infiltration was analyzed by R software.Results Kaplan-Meier survival analysis showed the total survival time of patients in the low-risk group was significantly higher than that of patients in the high-risk group of the training group(P<0.05).Compared with high risk group,the overall survival time of patients(G1～2,G3～4,Ⅰ～Ⅱ,or Ⅲ～Ⅳ,age≤65 years,or patients>65 years old)in low risk group was higher(P<0.05).Differential gene enrichment analysis was obtained for high and low risk groups,which mainly enriched with many differential genes such as muscle contraction,rhabdomytic cell differentiation,myofibril,receptor activation activity,and vascular smooth muscle contraction.The highest driver genes in high risk group and low risk group exhibited mutation frequency and mutation information,and their risk score was positively correlated with the degree of T cell and plasma cell infiltration(r=0.638,P=0.001).Conclusion Bioinformatics-based analysis of the N6-methyladenosine related LncRNA pairing models can be helpful to predict the prognosis of patients with renal cancer.It provides new ideas for the prognosis evaluation and optimal treatment strategy of renal cancer,and contributes to further analyzing the molecular mechanism of the occurrence and development of gastric cancer in the future.

Objectives:To analyze the location, discovery time and possible causes of cases of cervical cystic lymph node metastasis with an unknown primary misdiagnosed as branchial cleft carcinoma.Methods:A retrospective analysis was performed on clinical and pathological data of 15 patients misdiagnosed as branchiogenic carcinoma at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between January 2000 and December 2020.Results:Among the 15 patients, 6 were nasopharyngeal squamous cell carcinoma, 4 tonsil squamous cell carcinoma, 2 tongue root squamous cell carcinoma, 2 hypopharyngeal squamous cell carcinoma and 1 thyroid papillary carcinoma. The median time from the diagnosis of branchial cleft carcinoma to the discovery of primary lesions was 3.58 months (0-76 months). The causes of misdiagnosis might be the lack of experience in the diagnosis and treatment of branchial cleft carcinoma, and not enough attention to comprehensive examination and close follow-up.Conclusions:Different from oropharyngeal cancer reported internationally, the proportion of misdiagnosed cases with nasopharyngeal carcinoma as the primary site in the current article is higher. As a country with a high incidence of nasopharyngeal carcinoma, the examination of nasopharynx should not be taken lightly. Most hidden cases can be found in the comprehensive examination in a short time, while a few cases need long-term follow-up. Finding the primary sites should not rely too much on imaging examination, and we cannot ignore the importance of clinical physical examination.

Objective To analyze the clinical efficacy of Yunnan Baiyao in middle aged and elderly lung cancer patients undergoing the uniportal video-assisted thoracoscopic.Methods A total of 90 patients with non-small cell lung cancer meeting the criterias were screened and divided into two groups according to random number table method,which respectively received conventional treatment(control group)and Yunnan Baiyao treatment(experimental group).The perioperative period related indexes,coagulation function related indexes,and the occurrence rate of complications were observed and compared between the two groups.Results The intraoperative bleeding volume and thoracic drainage volume for the first day of experimental group were significantly lower than control group(P＜0.05).However,there were no significant difference in the coagulation function related indexes between two groups before and after surgery(P＞0.05).Additionally,there were also no significant difference in the occurrence rate of complication between two groups(P＞0.05).Conclusion Yunnan Baiyao can reduce intraoperative bleeding volume and chest tube drainage volume for the first day,promots the recovery of patients,and has a good clinical application value.

Objective:To prospectively observe the changes of tumor-related symptoms in patients with nasopharyngeal carcinoma following the administration of nimotuzumab one week before radiotherapy.Methods:Non-metastatic nasopharyngeal carcinoma patients with positive epidermal growth factor receptor (EGFR) expression and symptoms caused by the primary lesion or metastatic cervical lymph nodes admitted to Cancer Hospital of Chinese Academy of Medical Sciences were prospectively recruited. Investigators recorded tumor-related symptoms in recruited patients one day before the first administration of nimotuzumab (D0) and conducted follow-up visits from day 2 to day 7 after the first administration (D2-D7) to document symptom changes. All recruited patients were asked to assess tumor-related symptoms on D0 and D7 by visual analogue scale (VAS) scores. VAS scores were analyzed by paired t-test. Results:From June 2020 to April 2023, a total of 21 patients met the inclusion criteria. The median age was 49 years (range: 27-69 years), with a male-to-female ratio of 1.3:1. Among the patients, 17 patients (81%) received concurrent nimotuzumab for 8 cycles, 7 cycles for 3 cases (14%), and 6 cycles for 1 case (5%), respectively. All patients completed symptom assessments as required. The overall response rate of symptoms after the first administration of nimotuzumab was 62%, with response rates of 4/6、5/8、4/10、4/10、4/11、3/11 for tinnitus, headache, aural fullness, secondary pain caused by neck mass, nasal bleeding, and nasal obstruction, respectively. The VAS scores for overall symptoms were significantly decreased after the administration of nimotuzumab one week before radiotherapy ( P<0.001), with the most significant decrease in VAS scores for tinnitus, aural fullness, and headache. Conclusion:The administration of nimotuzumab one week before radiotherapy significantly alleviates tumor-related symptoms in patients with nasopharyngeal carcinoma, particularly in alleviating tinnitus, aural fullness, and headache.

Objective:To investigate the efficacy and safety of Enterprise stenting in the treatment of symptomatic middle cerebral artery atherosclerotic stenosis.Methods:Patients with symptomatic middle cerebral artery atherosclerotic stenosis underwent Enterprise stenting in the Department of Neurology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2020 to December 2022 were retrospectively included. The degree of residual stenosis, periprocedural complications, in-stent restenosis and stroke recurrence during follow-up were evaluated.Results:A total of 75 patients were enrolled, including 55 males (73.3%), aged 58±9.7 years.

Objectives To enhance occupational safety for medical practitioners involved in acupuncture procedures within the field of Chinese medicine,it is imperative to thoroughly investigate and analyze the current incidence of accidental punctures.Subsequently,effective strategies can be proposed to prevent such occurrences.Methods Through retrospective analysis,this study investigates the occupational exposure data of a tertiary hospital specializing in traditional Chinese medicine from 2020 to 2022.The demographic characteristics(age and gender),professional experience,occupational category,pre-service training,type of acupuncture tools used,puncture session details,and exposure sources of the individuals involved are collected and organized for analyzing the risk factors asso-ciated with accidental needlestick injuries.Corresponding preventive measures are proposed accordingly.Results In this survey,a total of 5 069 medical staff from 12 clinical departments were included,among whom 63 experienced accidental puncture with an incidence rate of 1.24%(63/5 069).The likelihood of puncture was found to be signifi-cantly higher in individuals aged between 25～30 years compared to those under the age of 25(OR=18.556,P＜0.05).Similarly,the probability of puncture was also higher in individuals aged over 30 years compared to those under the age of 25(OR=14.311,P＜0.05).Conversely,individuals with at least three years of experience had a lower probability of experiencing punctures compared to those with less than three years(OR=0.025,P＜0.05).Furthermore,interns exhibited a higher likelihood of puncture incidents compared to physicians(OR=2.212,P＜0.05).Regarding the puncture session,the highest probability of occurrence is 58.73%at the time of needle removal(χ2=106.222,P＜0.05).Regarding the type of acupuncture tools,acupuncture needles have the highest probability of occurrence at 41.27%(χ2=45.095,P＜0.05).Concerning the exposure source,"unknown exposure source"has the highest preva-lence at 42.86%(χ2=57.476,P＜0.05),while"exposure source is hepatitis B patient"accounts for 20.63%(χ2=57.476,P＜0.05).Regarding pre-service training,individuals who have received pre-service training exhibit a higher likelihood of puncture incidents(69.84%)(χ2=38.000,P＜0.05).Conclusions The serological status of patients should be obtained in advance,and strict adherence to infection prevention control measures such as"standard precau-tions"and"contact isolation"is necessary.Effective pre-service training must be implemented,with particular atten-tion given to the risk of puncture when using specialized acupuncture tools for occupational safety.

Five new terpenoids, including two vibsane-type diterpenoids (1, 2) and three iridoid allosides (3-5), together with eight known ones, were isolated from the leaves and twigs of Viburnum odoratissimum var.sessiliflorum. Their planar structures and relative configurations were determined by spectroscopic methods, especially 2D NMR techniques. The sugar moieties of the iridoids were confirmed as β-D-allose by GC analysis after acid hydrolysis and acetylation. The absolute configurations of neovibsanin Q (1) and dehydrovibsanol B (2) were determined by quantum chemical calculation of their theoretical electronic circular dichroism (ECD) spectra and Rh₂(OCOCF₃)₄-induced ECD analysis. The anti-inflammatory activities of compounds 1, 3, 4, and 5 were evaluated using an LPS-induced RAW264.7 cell model. Compounds 3suppressed the release of NO in a dose-dependent manner, with an IC₅₀ value of 55.64 μmol·L^-1. The cytotoxicities of compounds 1-5 on HCT-116 cells were assessed and the results showed that compounds 2 and 3 exhibited moderate inhibitory activities with IC₅₀ values of 13.8 and 12.3 μmol·L^-1, respectively.
