Based on the theory of "disease involving both dryness and dampness"， it is believed that the complex of dryness and dampness and the mutual stalemate between them produce the disease， forming a pathological state of dampness within dryness and dryness within dampness. The two can occur accompanied by each other， transform into each other， and coexist as a disease. According to the clinical characteristics of sjögren's syndrome-related dry eye disease （SS-DED）， it is believed that its symptoms can reflect the pathological state of coexistence of dryness and dampness， and that "disease involving both dryness and dampness" is the key pathogenesis. The main treatment principles are performing both purgation and tonification， and treating the dryness and dampness simultaneously. The treatment should focus on rectifying qi， fortifying spleen and dispelling dampness， as well as opening orifices， nou-rishing yin and moistening dryness， usually with Shashen Maidong Decoction （沙参麦冬汤） and Xiangsha Liujunzi Decoction （香砂六君子汤） in modifications. The theory of "disease involving both dryness and dampness" is expected to provide ideas for the diagnosis and treatment of SS-DED.

Objective To explore the efficacy and safety of enhanced external counterpulsation(EECP)in elderly patients with acute ischemic stroke(AIS)complicated by coronary heart dis-ease(CHD).Methods A total of 65 AIS patients with CHD admitted in our hospital from Janu-ary to June 2023 were recruited and randomly divided into a control group(drug secondary pre-vention,n=32)and a treatment group(drug combined with EECP therapy,n=33).Their NIHSS score,mRS score and Canadian Cardiovascular Society(CCS)angina grade were evaluated before and after treatment and compared between the two groups.The incidences of recurrent ischemic stroke,new hemorrhagic stroke and major adverse cardiovascular events(MACE)were also recor-ded during treatment.Results The NIHSS score and mRS score were significantly decreased in both groups after treatment(P＜0.01).After treatment,the NIHSS score(2.67±1.63 vs 3.56± 1.83),mRS score[1.0(0.0,1.0)vs 2.0(1.0,2.0)]and CCS grade[1.0(1.0,2.0)vs 2.0(1.0,2.0)]were obviously lower in the treatment group than the control group(P＜0.05,P＜0.01).There were no statistical differences in the incidence rates of recurrent ischemic stroke,new-onset hem-orrhagic stroke,and MACE between the control group and the treatment group(9.4％vs 6.1％,6.3％vs 3.0％,12.5％vs 6.1％,P＞0.0 5).Conclusion EECP is a safe and effective treatment option for elderly AIS patients with CHD.

OBJECTIVE To analyze the clinicopathological features of laryngeal squamous carcinoma tumors and their correlation with prognosis in order to improve the understanding and diagnosis of laryngeal squamous cell carcinoma.METHODS The clinical and pathological data(including gender,age,stage,differentiation,immunohistochemistry,etc.)of 179 patients with laryngeal squamous cell carcinoma[171 males,8 females,aged 30-84(61.53±8.02)years]who were treated in Department of Otolaryngology Head and Neck Surgery,The First and Second Clinical Medical Schools of Ningxia Medical University from January 2015 to December 2022 were retrospectively studied,and the effects of various factors on prognosis were analyzed.RESULTS Among the 179 patients with laryngeal squamous cell carcinoma,the male-to-female ratio was 21.4:1,and the incidence was high in the age group of 60-79 years old(58.7%),and the youngest age of onset was 30 years old.The main clinical manifestations were hoarseness 138 cases(77.1%),sore throat 16 cases(8.9%)and pharyngeal foreign body sensation 13 cases(7.3%).Glottic type was more common in the primary site 135 cases(75.4%),and 31 cases were accompanied by cervical lymph node metastasis(17.3%).The degree of differentiation was more common in the moderately differentiated type 80 cases(44.7%).The positive rates of immunohistochemistry markers p16,EGFR(epidermal growth factor receptor),PD-1/PD-L1 and VEGF(vascular endothelial growth factor)were 20.3%,96.4%,36.4%and 77.3%,respectively.Univariate Kaplan-Meier survival analysis showed that the site of disease,lymph node metastasis,and tumor stage were significantly correlated with disease recurrence.Multivariate Cox regression analysis showed that the clinical stage of the tumor was an independent risk factor for the prognosis of the disease(HR=3.715,95%CI:1.519-9.088,P=0.04).CONCLUSION The stage of laryngeal squamous cell carcinoma,the site of the disease,and the metastasis of the lymph nodes are the main factors affecting the prognosis.The high positive expression rate of immunohistochemistry markers EGFR and VEGF is worth paying attention to Targeted therapy for patients with positive PD-1/PD-L1 testing is a promising research direction.

Glucose transporter 1(GLUT1)overexpression in tumor cells is a potential target for drug therapy,but few studies have reported screening GLUT1 inhibitors from natural or synthetic compounds.With cur-rent analysis techniques,it is difficult to accurately monitor the GLUT1 inhibitory effect of drug molecules in real-time.We developed a cell membrane-based glucose sensor(CMGS)that integrated a hydrogel electrode with tumor cell membranes to monitor GLUT1 transmembrane transport and screen for GLUT1 inhibitors in traditional Chinese medicines(TCMs).CMGS is compatible with cell membranes of various origins,including different types of tumors and cell lines with GLUT1 expression knocked down by small interfering RNA or small molecules.Based on CMGS continuous monitoring technique,we inves-tigated the glucose transport kinetics of cell membranes with varying levels of GLUT1 expression.We used CMGS to determine the GLUT1-inhibitory effects of drug monomers with similar structures from Scutellaria baicalensis and catechins families.Results were consistent with those of the cellular glucose uptake test and molecular-docking simulation.CMGS could accurately screen drug molecules in TCMs that inhibit GLUT1,providing a new strategy for studying transmembrane protein-receptor interactions.

Objective:To investigate the clinicopathological features,immunophenotype,and prognosis of head and neck spindle cell squamous cell carcinoma(SCSCC)to improve the understanding and diagnosis of this tumor.Methods:Clinicopathological data collected from January 2012 to December 2022 at the First Affiliated Hospital,Air Force Military Medical University from 20 patients with head and neck SCSCC were retrospectively reviewed for histological morphology and immunophenotype.In situ and fluorescence in situ hybridization were performed to detect EBV-encoded ribonucleic acid(EBER)status and MDM2 gene amplification,respectively.Results:The median age among the 20 SCSCC cases was 67 years with a male-to-female ratio of 4∶1.Tumor locations were laryngeal(35.0%)and sinonasal(30.0%).SCSCC presented as polypoid or exogenous growths(61.5%),often with surface ulceration(90.0%).Histologically,sarcomatoid growth pat-terns were exhibited in 75.0%of the patients(n=15),while the remainder showed granular tissue-like or angiosarcomatoid patterns.Most tumors(65.0%)displayed components of conventional squamous cell carcinomas,with a predominant occurrence of high to moderate dif-ferentiation(91.7%).In terms of immunohistochemistry,AE1/AE3 was expressed in 83.3%(15/18)of cases,while p63 and p40 expression rates were 62.5%and 66.7%,respectively.All cases were negative for EBER.The Ki-67 proliferation index ranged 10%-70%.Overall,33.3%(1/3)of the cases showed MDM2 gene amplification.Among these,the median follow-up time for 18 patients was 18.3 months(range:1-92 months),with 6 survivors and 12 deaths.Conclusions:Head and neck SCSCC is more prevalent among elderly male smokers,predominantly exhibits a polypoid growth pattern,and does not display human papillomavirus or Epstein-Barr virus infection.Diagnosis requires a compre-hensive evaluation of clinical and pathological features and immunophenotype.Surgical resection is the primary treatment method.

Objective To investigate the diagnostic value of high-resolution magnetic resonance im-aging(HRMRI)in elderly patients with non-cardioembolic acute ischemic stroke(NCAIS).Meth-ods A retrospective analysis was conducted on 101 elderly NCAIS patients having HRMRI in our hospital from July 2022 to July 2023.Stroke subtypes were classified according to the Trial of Org 10172 in Acute Stroke Treatment(TOAST)system and the Chinese Ischemic Stroke Sub-classification(CISS)system.The constituent ratio distribution of each subtype classification was compared before and after HRMRI in both classification systems.Results TOAST system identi-fied 8 cases of small-artery occlusion(SAO),1 case of other determined etiology(SOE),5 cases of undetermined etiology(SUE)and then reclassified as large artery atherosclerosis(LAA),1 case of SUE which was reclassified as SAO,and 7 cases of LAA and 4 cases of SUE being reclas-sified as SOE after HRMRI.In total,the diagnosis of 26 cases(25.74％)was modified.In the CISS system,10 cases of penetrating artery disease(PAD),1 case of other etiologies(OE),and 4 cases of undetermined etiology(UE)were reclassified as LAA.Furthermore,9 cases of LAA and 3 cases of UE were reclassified as OE after HRMRI.In total,the diagnosis of 27 cases(26.73％)was modified.There were statistical differences in the constituent ratio before and after HRMRI in both TOAST(x2=15.425,P＜0.01)and CISS(x2=17.300,P＜0.01)systems.Conclusion HRMRI is of diagnostic value and significance in accurately diagnosing the etiology of AIS in eld-erly patients without cardioembolic causes.

Objective:To explore the application value of three-dimensional visualization technique based on CT data in the analysis of renal vascular anatomical variation.Methods:The clinical data of 210 patients with renal tumors, adrenal tumors and renal cysts who underwent renal enhanced CT from October 2020 to June 2021 were retrospectively analyzed. Among the patients, there were 114 males and 96 females with an average age of (56.5±13.2) years. The CT data were reconstructed by 3D slicer software. According to the three-dimensional visualization model, the renal vascular anatomy was analyzed from the perspective of whether it needs to be treated during laparoscopic radical nephrectomy and laparoscopic partial nephrectomy. The variation of renal artery can be divided into multiple renal arteries, premature branches of renal artery and the mixed type with the above two variations. Renal vein variation can be divided into multiple renal veins, late confluence of renal veins and mixed type with the above two variations.Results:Among the 210 patients in this study, there were no statistically significant differences in anatomical variations of renal arteries and veins between males and females ( P=0.914 and P=0.121). Among 420 kidneys, renal artery variation (174/420, 41.4%) was more common than renal vein variation (121/420, 28.8%) ( P<0.01). 32 (7.6%) right kidneys and 38 (9.0%) left kidneys have multiple renal arteries ( P=0.432). Eighty-nine cases (42.4%) had premature branches in the right renal artery, while 37 cases (17.6%) in the left kidney ( P<0.01). 24 kidneys (5.7%) showed mixed renal artery variation. 53 (12.6%) right kidneys and 3 (0.7%) left kidneys had multiple renal veins ( P<0.01). Late confluence of renal veins was found in 41 right kidneys (9.8%) and 33 left kidneys (7.9%), respectively ( P=0.306). 8 (1.9%) mixed renal vein variants were all right kidneys.. From the perspective of laparoscopic renal surgery, there were 71 cases (33.8%) of the left kidney to deal with ≥ 2 renal arteries, as well as 103 cases (49.1%) of the right kidney ( P<0.01). There were 44 cases (21.0%) of the left kidney to deal with ≥ 2 renal veins, as well as 78 cases (37.1%) of the right kidney ( P<0.01). Conclusions:The three-dimensional visualization technique based on renal CT data is helpful to accurately evaluate the renal vascular anatomy before operation. Right renal vascular variants are more common.

Objective To investigate tumor cell killing effect of superparamagnetic Fe3O4 nanoparticles with cubic phase through magneto-mechanical force under a low-frequency vibrating magnetic field ( VMF). Methods A kind of strong magnetic and irregular-shaped Fe3O4 nanoparticles with cubic phase was synthesized by coprecipitation method. The Fe3O4 nanoparticles were exposed to a self-developed VMF and cell killing efficiency of the Fe3O4-mediated magneto-mechanical force was investigated. Results VMF alone had no effects on cell viability. After Fe3O4 nanoparticles were added, the cell viability significantly decreased with prolonging the VMF treatment time and increasing the Fe3O4 nanoparticle concentration. Lactate dehydrogenase released by damaged cells also increased with prolonging the VMF exposure time. Conclusions The irregular-shaped Fe3O4 nanoparticles can transfer magneto-mechanical force to tumor cells under VMF, cause structural damage of cells and result in cell death. The VMF generator developed in this study has simple structure and it is safe for use and convenient for operation. The developed magnetic nanoparticles and the corresponding cancer cell killing technique have the potential for clinical transformation.
