In this paper， the name， origin， producing area， harvesting， processing and functional indications of Arcae Concha were systematically combed and verified by consulting the ancient and modern literature， in order to provide a basis for the development of famous classical formulas containing Arcae Concha. Arcae Concha was first recorded in the name of Han in Bencao Shiyi， but later， due to the influence of LI Shizhen's error of combining Han item with Kuiha in the Ming dynasty， there were aliases such as Kuilu and Fulao， and Yizong Bidu began to include Walengzi as its correct name and has been used ever since. The textual descriptions and illustrations of the medicinal materials of Arcae Concha contained in the materia medica of the past generations were consistent with the modern Arca inflata， A. subcrenata and A. granosa. In ancient times， there were medicinal records of two parts of shell and meat， but now the shell is used as medicine， and the meat is mostly edible. In ancient times， Zhejiang， Shandong， Guangdong and Guangxi were the main producing areas， and Zhejiang was the best. It is now believed that A. inflata is mostly distributed in the northern part of the Huanghai Sea， A. granosa is mostly distributed in the coastal areas south of Shandong Peninsula in China， and A. subcrenata is widely distributed in the coastal areas of China. Its quality is better in a complete， white， no residual meat and sand. In ancient times， there was no clear harvesting period， and the processing was mainly based on vinegar quenching after calcination or powdering of calcined shell， but now the harvesting period is autumn and winter. After harvesting， it is directly washed and crushed for raw use or processed by calcined method. The records of the medicinal materials in the past dynasties on the properties of Arcae Concha were mainly warm， sweet， salty and mild， and it is now believed that Arcae Concha is salty in taste and mild in nature. In ancient times， it was believed that Arcae Concha were mainly used for coldness in the heart and abdomen， coldness in the waist and spine， benefiting the five internal organs， strengthening the stomach. Nowadays， it is believed that Arcae Concha can eliminate phlegm and remove blood stasis， soften the hardness and dissipate the lumps， produce acid and relieve pain. It can be used in the treatment of stubborn phlegm， gall tumor， scrofula and other symptoms. In conclusion， it is suggested that for the famous classical formulas containing Arcae Concha， the corresponding methods should be selected according to the processing requirements of the drug in the formulas， while those without processing requirements can be determined according to the functional position of the products.

ObjectiveTo investigate the pharmacodynamic effects of Houshihei San （HSHS） recorded with the effects of treating wind and limb heaviness on muscle tissue injury after middle cerebral artery occlusion （MCAO） in rats through the ferroptosis pathway. MethodsThirty SD male rats were selected and randomly grouped as follows： sham， MCAO， deferoxamine mesylate， high-dose HSHS （HSHS-H， 0.54 g·kg^-1）， and low-dose HSHS （HSHS-L， 0.27 g·kg^-1）， with 6 rats in each group. A laser scattering system was used to evaluate the stability of the MCAO model， and rats were administrated with corresponding agents by gavage for 7 days. During the administration period， behavioral， imaging and other methods were used to systematically evaluate the skeletal muscle tissue injury after MCAO and the therapeutic effect in each administration group. Hematoxylin-eosin staining was employed to evaluate the cross-section of muscle cells. Subsequently， immunohistochemistry was used to detect tumor suppressor p53 and glutathione peroxidase 4 （GPX4） in the soleus tissue. Western blot was employed to determine the protein levels of p53， GPX4， myogenic differentiation 1 （MyoD1）， nuclear factor E₂-related factor 2 （Nrf2）， Myostatin， solute carrier family 7 member 11 （SLC7A11）， muscle ring-finger protein-1 （MuRF1）， and muscle atrophy F-box protein （MAFbx） to verify the therapeutic effect in each group. ResultsCompared with the MCAO group， HSHS enhanced the locomotor ability and promoted muscle regeneration， which suggested that the pharmacological effects of HSHS were related to the inhibition of muscle tissue ferroptosis to reduce the expression of muscle atrophy factors. Behavioral and imaging results suggested that compared with the MCAO group， HSHS ameliorated neurological impairments in rats on day 7 （P<0.01）， enhanced 5-min locomotor distance and postural control （P<0.01）， strengthened grasping power and promoted muscle growth （P<0.01）， stabilized skeletal muscle length and weight （P<0.01）， and increased the cross-section of muscle cells （P<0.01）. Compared with the MCAO group， HSHS promoted the increases in glutathione and superoxide dismutase content and inhibited the increase in malondialdehyde content （P<0.05，P<0.01）. Ferroptosis pathway-related assays suggested that HSHS reduced the p53-positive cells and increased the GPX4-positive cells （P<0.01）. HSHS ameliorated muscle function decline after stroke by promoting the expression of GPX4， Nrf2， SLC7A11， and MyoD1 and inhibiting the expression of p53， Myostatin， MurRF1， and MAFbx to reduce ferroptosis in the muscle （P<0.01）. ConclusionHSHS， prepared with reference to the method in the Synopsis of Golden Chamber， can simultaneously reduce the myolysis and increase the protein synthesis in the skeletal muscle tissue after ischemic stroke by regulating the ferroptosis pathway.

Through consulting the ancient herbal books and modern literature， this paper has carried out the textual research on the name， origin， place of origin， harvesting and processing， and other contents of Bruceae Fructus， combed its ancient and modern medicinal history， so as to provide reference for the development of famous classical formulas containing Bruceae Fructus. Through the herbal textual research， It can be verified that， since the Qing dynasty， Bruceae Fructus has been recorded in the materia medica， most of the materia medica in previous dynasties took Bruceae Fructus as its proper name， and Laoyadan， Kushenzi and Yadanzi as the aliases. The main origin of Bruceae Fructus is Brucea javanica， its medicinal part is the fruit， which is harvested from August to October every year， the fruit can be harvested when it is ripe. Bruceae Fructus was first distributed in Fujian， Guangdong and Guangxi， and gradually expanded to the south of China with the change of time. The traditional processing method of Bruceae Fructus is mainly to remove the shell and kernel， and remove the oil by frosting. The 2020 edition of Chinese Pharmacopoeia stipulates that its processing method is to remove the shell and impurities. Based on the research results， it is suggested that the dried mature fruit of B. javanica should be selected for the development of famous classical formulas containing this herb， and the raw products can be used if the original formula does not specify the processing requirements.

Objective:To explore the gene mutation characteristics and the relationship between gene mutations and long-term prognosis in clinical stage ⅠA lung adenocarcinoma patients.Methods:A retrospective analysis was conducted on 63 clinical stage ⅠA lung adenocarcinoma patients who underwent surgical resection at the Cancer Hospital of the Chinese Academy of Medical Sciences from January 2007 to October 2012, with documented postoperative recurrence or metastasis, as well as those who had a follow-up duration of 10 years or more without recurrence or metastasis. Whole exome sequencing (WES) technology was used to analyze the gene mutation profiles in tumor tissues and univariate and multivariate Cox regression analysis were used to clarify the influencing factors for patient prognosis.Results:After long term follow-up, 13 out of the 63 patients (21%) experienced recurrence or metastasis. WES technology analysis revealed that the most common tumor related gene mutations occurred in epidermal growth factor receptor (EGFR), with a mutation rate of 65.1% (41/63), followed by tumor protein p53 (TP53), fatatypical cadherin 1 (FAT1), low density lipoprotein receptor-related protein 1B (LRP1B), mechanistic target of rapamycin (MTOR), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit gamma (PIK3CG), and SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily A, member 4 (SMARCA4), with mutation rates of 30.2% (19/63), 20.6% (13/63), 15.9% (10/63), 15.9% (10/63), 15.9% (10/63), and 15.9% (10/63), respectively. Multivariate Cox regression analysis showed that PIK3CG mutations ( HR=21.52, 95% CI: 3.19-145.01),smoothened (SMO) mutations ( HR=35.28, 95% CI: 3.12-398.39), catenin beta 1 (CTNNB1) mutations ( HR=332.86, 95% CI: 15.76-7 029.05), colony stimulating factor 1 receptor (CSF1R) mutations ( HR=8 109.60, 95% CI: 114.19-575 955.17), and v-Raf murine sarcoma viral oncogene homolog B (BRAF) mutations ( HR=23.65, 95% CI: 1.86-300.43) were independent risk factors affecting the prognosis of clinical stage ⅠA lung adenocarcinoma patients. Conclusions:PIK3CG, SMO, CTNNB1, CSF1R, BRAF gene mutations are closely related to long-term recurrence or metastasis in clinical stage ⅠA lung adenocarcinoma. Patients with these gene mutations should be given closer clinical attention.

Objective:To investigate the expression and correlation of C-reactive protein(CRP)with IL-18,IL-37 in gingival crevic-ular fluid(GCF)after invisible orthodontics treatment and fixed orthodontics treatment respectively.Methods:10 patients with invisible orthodontic treatment were included in the study group,and 12 patients with fixed orthodontic treatment were included in the control group.The expression levels of IL-18,IL-37 and CRP in GCF before,24 h,1 and 3 months after orthodontic treatment were detected by ELISA.Results:Before orthodontic treatment,there was no significant difference in the expression levels of IL-18,IL-37 and CRP in GCF between the 2 groups(P＞0.05).The expression levels of IL-18,IL-37 and CRP in GCF increased at 24 h after treatment,and those in the study group were higher than in the control group(P＜0.05).After 1 month of treatment,those in the study group were low-er than in the control group(P＜0.05).After 3 months of treatment,the expression levels of the factors were not statistically different between the 2 groups(P＞0.05).The leves of CRP,IL-18 and IL-37 in GCF were positivelly correlated in both groups(P＜0.001).Conclusion:The levels of IL-18,IL-37 and CRP in GFC in the subjects treated with invisible correction are increased due to high stress stimulation in a period of 24 hours,suggesting that the effect on the periodontal tissue by the invisible correction may be greater than that by the fixed correction.

Objective:To analyze the characteristics of peripheral blood lymphocyte subsets in patients with relapsed neuromyelitis optica spectrum disorder (NMOSD) during rituximab (RTX) treatment and to clarify the influence of these lymphocyte subsets in NMOSD relapse.Methods:The monitoring data of lymphocyte subsets (175 times) in 76 patients diagnosed as having aquaporin-4-immunoglobulin G (AQP4-IgG)-seropositive NMOSD during RTX treatment at Department of Neurology, General Hospital of Chinese People's Liberation Army from August 2018 to August 2023 were collected. A relapse group ( n=26) and a non-relapse group ( n=149) were divided based on states at data collection (relapse or not). Two-sample t-test or Mann-Whitney U test were used to compare the differences in RTX administration intervals and lymphocyte subsets between the 2 groups. Additionally, a point biserial correlation analysis was performed to investigate the correlations of lymphocyte subsets and RTX administration intervals with NMOSD relapse. Results:The relapse group had significantly longer RTX administration intervals (10.00 [6.73, 14.37] months vs. 7.27[6.30, 9.10] months), statistically lower percentage of CD3 -CD56 + natural killer lymphocytes (10.72% [7.06%, 15.34%) vs. 13.85% [9.42%, 20.13%]), and significantly higher CD19 + B lymphocytes (7.41% [1.18%, 15.70%] vs. 3.55% [0.38%, 8.74%]) than the non-relapse group ( P<0.05). Positive correlations were noted between RTX administration intervals and NMOSD relapse and between CD3 -D19 +B lymphocytes and NMOSD relapse ( r=0.363, P<0.001; r=0.218, P=0.004); negative correlation was noted between CD3 -CD56 + NK lymphocytes and NMOSD relapse ( r=-0.193, P=0.011). Conclusion:Extended RTX administration interval can increase NMOSD relapse; CD3 -CD56 + natural killer lymphocytes and CD19 +B lymphocytes may regulate the disease states of NMOSD patients.

Benign paroxysmal positional vertigo (BPPV) is a peripheral vestibular disease with the highest incidence rate, and the elderly are the high incidence population. Particle repositioning maneuver, simple and practicable, and has good clinical effects, is recognized as the preferred treatment method for BPPV. However, the elderly patients have a higher prevalence rate, often suffer from multiple chronic diseases, and their various bodily functions have entered a declining stage, with poor response to treatment and a tendency to recur. Based on these, medical staff should continuously improve their professional abilities, and pay attention to and implement some comprehensive and multi-dimensional humanistic care measures from physiological to psychological aspects such as verbal encouragement, behavioral support, and spiritual integration during the diagnosis and treatment process, to improve the quality of life of elderly BPPV patients, reduce medical disputes, and save medical resources.

Objective:To evaluate the influence of an additional roll test on the repositioning procedure by SRM-vertigo diagnosis system for horizontal canal benign paroxysmal positional vertigo（HC-BPPV）. Methods:A total of 713 patients diagnosed with HC-BPPV in Department of Otolaryngology Head and Neck Surgery，the First Affiliated Hospital of Xi'an Jiaotong University from Jan 2020 to Feb 2022 were enrolled. The patients were divided into two groups by hospital card numbers, in which the number is odd were considered as group A, and the number is even were considered as group B. The group A underwent two circles of Barbecue repositioning procedure by SRM-vertigo diagnosis system, while the group B first performed an additional roll test and then underwent two circles of Barbecue repositioning procedure by SRM-vertigo diagnosis system, to observe the cure rate and compare influence of HC-BPPV by an additional roll test. The quality of life and sleep of patients before and one-month after the treatment were assessed by the dizziness handicap inventory（DHI） and the pittsburgh sleep quality（PSQI）. Results:The cure rate of group A was 63.21%, and the cure rate of group B was 87.68%，the difference between the two groups was statistically significant（P<0.05）; The DHI score of patients after the repositioning was significantly lower than that before the repositioning（P<0.05）. The PSQI score after the repositioning was significantly lower than that before the repositioning（P<0.05）. The DHI and the PSQI scores after the repositioning were significantly lower than that before the repositioning, with a statistically significant difference （P< 0.05）. The total score of DHI in group B after treatment was lower than that in group A, with a statistically significant difference（P<0.05）. The total score of PSQI in group B after treatment was lower than that in group A, with non-statistically significant difference （P< 0.05）. Conclusion:An additional roll test before the repositioning procedure by SRM-vertigo diagnosis system can significantly improve the cure rate of HC-BPPV, relieve anxiety, and improve the quality of life.
