ObjectiveThis study aimed to explore the correlation between the quality of life （QOL） and different traditional Chinese medicine （TCM） syndromes in patients with myasthenia gravis （MG）， identifying potential influencing factors to provide new insights for clinical interventions and improving the QOL of patients with MG. MethodsA questionnaire survey was conducted on 93 adults with MG who visited the Department of Neurology at the Affiliated Hospital of Changchun University of Chinese Medicine from March 2023 to January 2024. Statistical analysis was performed on the clinical data collected using SPSS 24.0 software. ResultsAmong the 93 patients with MG， the average score for myasthenia gravis quality of life-15 （MGQOL-15） was 17.65±6.27， and that for the 36-item short form health survey （SF-36） was （106.13±11.83） scores. The QOL was rated as good for 16 patients and moderate for 77 patients. There were no statistically significant differences in the scores of MGQOL-15， SF-36， and their individual scales by gender or education level. Age showed statistically significant differences in MGQOL-15 and the role physical （RP） scale （P<0.05）， and occupational type showed significant differences in the vitality （VT） scale （P<0.01）. The Myasthenia Gravis Foundation of America （MGFA） classification had statistical significance on the total SF-36 score （P<0.01）， VT scale （P<0.01）， role emotional （RE） scale （P<0.05）， social functioning （SF） scale （P<0.05）， and physical functioning （PF） scale （P<0.01）. Among patients with different TCM syndromes， there were significant differences in MGQOL-15 scores （F=4.919， P<0.01）. Moreover， significant differences were observed in SF-36 scores （P<0.01）， VT scale （P<0.01）， RE scale （P<0.05）， mental health （MH） scale （P<0.01）， and SF scale （P<0.05）. ConclusionFactors affecting the QOL of patients with MG include age， occupational type， and clinical classification of MG. Specifically， a greater impact on the QOL of older patients is observed， while physical laborers have a poorer QOL compared to non-physical laborers. Patients classified as MGFA type Ⅱ and higher have a poorer QOL. Additionally， there is a potential correlation between the QOL and TCM syndromes， with patients presenting with spleen and kidney Qi deficiency having a lower QOL than those with spleen and stomach Qi deficiency or Qi and Yin deficiency， which is particularly evident in the VT， RE， MH， and SF scales.

In September 8 th, 2021, a male patient (aged 18 years) with severe destructive injuries of high-voltage electric burns in the head, face, and neck was admitted to General Hospital of Taiyuan Iron Steel (Group) Co., Ltd. Based on the economic theory of flaps, the flap donor site and transplantation method were optimized and evaluated before surgery, and then debridement of head, face, and neck wounds+removal of necrotic skull+free transplantation of super large latissimus dorsi myocutaneous flap+thin intermediate thickness skin graft transplantation from the left thigh was performed. The extra large flap donor site wound was sutured directly. This surgery reduced the adverse consequences of the flap donor site on the premise of ensure of repair effect. After operation, the patient's condition was stable, the flap and skin graft survived well, the repair effect of wound was well, the scar in the flap donor area was relatively mild, and the upper limb had no dysfunction.

Objective To compare the effects of visual rigid laryngoscope and visual laryngoscope in nasotracheal intubation(NTI)for patients with cervical spine immobilization simulated difficult airway.Methods Ninety patients scheduled for selective surgery under general anesthesia requiring NTI,52 males and 38 females,aged 18-64 years,BMI 18.5-25.0 kg/m2,ASA physical status Ⅰ or Ⅱ,were scheduled for selective surgery under general anesthesia requiring NTI.Before anesthesia induction,the spinal surgeon selected an appropriate cervical collar and adjusted it to fix patient's neck to establishing difficult airway sim-ulation model.All patients were randomly assigned into two groups:visual rigid laryngoscope(group R)and common visual laryngoscope(group C),45 patients in each group.NTI was performed using either visual rigid laryngoscope or visual laryngoscope in groups R and C,respectively.The nasal passage time,glottic exposure time,intubation time,number of successful first intubation attempts,and intubation attempts were recorded.Glottic exposure was assessed using the Cormack-Lehane(C-L)grading system,and the intuba-tion condition was quantitatively evaluated using the modified nasal intubation difficulty scale(NIDS).The blood pressure and heart rate were measured at baseline(T1),immediately after intubation(T2),and at 1 minute(T3)and 3 minutes(T4)after intubation.The occurrence of intubation-related complications(nasal bleeding,sore throat,hoarseness)was recorded.Results Compared with group C,the nasal passage time and proportion of successful intubations without difficulty were significantly increased in group R,and the glottic exposure time and intubation time were significantly decreased in group R(P<0.05).Compared with group C,the HR and MAP at T2 and T3 were significantly decreased in group R(P<0.05).Com-pared with group C,group R had significantly lower incidence rates of nasal bleeding,sore throat,and hoarseness(P<0.05).There were no statistically significant differences in the first intubation success rate,number of intubation attempts,or C-L grade between the two groups.Conclusion Patients with cer-vical spine immobilization simulated difficult airway,both visual rigid laryngoscope and visual laryngoscope can be performed safely and effectively in NTI.Compared with visual laryngoscope,visual rigid laryngoscope can provide faster glottic exposure,shorter intubation time,lower intubation difficulty,less hemodynamic impact,and lower incidence of complications.

Purpose: Loss-of-function mutations in the adenomatous polyposis coli (APC) gene are common in metastatic colorectal cancer (mCRC). However, the characteristic of APC specific mutations in mCRC is poorly understood. Here, we explored the clinical and molecular characteristics of N-terminal and C-terminal side APC mutations in Chinese patients with mCRC. Materials and Methods: Hybrid capture-based next-generation sequencing was performed on tumor tissues from 275 mCRC pati-ents to detect mutations in 639 tumor-associated genes. The prognostic value and gene-pathway difference between APC specific mutations in mCRC patients were analyzed. Results: APC mutations were highly clustered, accounting for 73% of all mCRC patients, and most of them were truncating mutations. The tumor mutation burden of the N-terminal side APC mutations group (n=76) was significantly lower than that of the C-terminal side group (n=123) (p < 0.001), further confirmed by the public database. Survival analysis showed that mCRC patients with N-terminus side APC mutations had longer overall survival than C-terminus side. Tumor gene pathway analysis showed that gene mutations in the RTK/RAS, Wnt and transforming growth factor β signaling pathways of the C-terminal group were significantly higher than those of the N-terminal group (p < 0.05). Additionally, KRAS, AMER1, TGFBR2, and ARID1A driver mutations were more common in patients with C-terminal side APC mutations. Conclusion APC specific mutations have potential function as mCRC prognostic biomarkers. There are obvious differences in the gene mutation patterns between the C-terminus and N-terminus APC mutations group, which may have certain guiding significance for the subsequent precise treatment of mCRC.

Stroke is one of the most common cerebrovascular diseases， including hemorrhagic stroke and ischemic stroke. From a modern medical perspective， stroke is caused by cerebrovascular damage or embolism leading to impaired blood circulation. From the traditional Chinese medicine （TCM） perspective， the pathogenesis of this disease is mainly due to the disorder of Qi and blood， which ascend to the brain， causing either blood extravasation or blockage of brain collaterals. Stasis is a pathological factor that runs throughout the entire course of stroke， and the method of promoting blood circulation and resolving stasis has been a core treatment for stroke for a long time. Hirudo， as a traditional insect drug， has shown good effects in promoting blood circulation and resolving stasis. Modern pharmacological research has confirmed that Hirudo contains anticoagulant components， which provide significant advantages in dissolving thrombi in ischemic stroke and facilitating hematoma absorption in hemorrhagic stroke. Hirudo and its related preparations have been proven to exert an anti-stroke effect through anticoagulation， anti-thrombosis， and protection of vascular endothelium. As a result， they have been widely used in the treatment of stroke. This article explored the theoretical basis and research status of using Hirudo for treating stroke based on its main active components and hemostatic properties and summarized the current research status of commonly used Hirudo-based formulations and preparations， aiming to provide references for the involvement of Hirudo in stroke treatment.

Tyrosine-decahydrofluorene derivatives are a class of hybrid compounds that integrate the properties of polyketides and nonribosomal peptides. These compounds feature a [6.5.6] tricarbocyclic core and a para-cyclophane ether moiety in their structures and exhibit anti-tumor and anti-microbial activities. In this study, we constructed the biosynthetic pathway of xenoacremones from Xenoacremonium sinensis ML-31 in the Aspergillus nidulans host, resulting in the identification of four novel tyrosine-decahydrofluorene analogs, xenoacremones I-L (1-4), along with two known analogs, xenoacremones A and B. Remarkably, compounds 3 and 4 contained a 12-membered para-cyclophane ring system, which is unprecedented among tyrosine-decahydrofluorene analogs in X. sinensis. The successful reconstruction of the biosynthetic pathway and the discovery of novel analogs demonstrate the utility of heterologous expression strategy for the generation of structurally diverse natural products with potential biological activities.
