Objective To investigate the clinical characteristics of 31 patients suffering from ANCA associated vasculitis(AAV).Methods The clinical data of 31 patients with ANCA positive profiles diagnosed as AAV were analyzed,including ANCA spectrum,renal and other organs' clinical features.Results There were 16 males and 15 females,average admission age(54.19?20.00)years(18 to 84 years).Totally 27 MPA and 4 WG were diagnosed;onset symptoms of renal involvement were in 15 cases and others in 16 cases;18 patients had respiratory system involvements including 8 cases with pulmonary hemorrhage.In admission 27 MPA patients with average SCr(460.42?354.55)?mol/L,and WG group with(659.62?535.1)?mol/L.ANCA spectrum showed 24 P-ANCA cases and 7 C-ANCA cases,while ELISA method showed 25 anti-MPO cases and 6 anti-PR3 cases.Conclusion AAV has many kinds of manifestations and progresses in many variable ways.Kidney and respiratory system are most vulnerable in AAV.The treatment is very limited in advanced stage of AAV.The key to improving the outcome of AAV is early detection of ANCA and early diagnosis.

Objective To evaluate the feasibility and safety of a delivery pathway for the performance of percutaneous left atrial appendage (LAA) occlusion in experimental canine models. Methods Transseptal puncture was performed via femoral vein approach under fluoroscopic and angiographic guidance in 12 experimental dogs. A pigtail catheter was advanced into the left atrium (LA), which was followed by LA angiography. The diameters of the neck of LAA were measured on LAA angiogram obtained in appropriate projection. After the delivery sheath was advanced along the wire into LA, a pigtail catheter was inserted into the ostium of the LAA and the sheath was then advanced over the pigtail into the LAA. LAA angiography was then performed through the delivery sheath to confirm the position of the delivery sheath. One hour after the procedure both electrocardiography (ECG) and transthoracic echocardiography (TTE) were carried out in five dogs to check the results, immediately after which the five dogs were sacrificed to macroscopically observe the damages of the puncture site of inter-atrial septum as well as inside the LA and LAA. One hour and 2 weeks after the procedure TTE was conducted in the remaining 7 dogs and these dogs were followed up for one month. Results One dog died of pericardial tamponade during the operation. In 8 dogs the LAA was clearly displayed in the projection position of right anterior oblique (RAO) 30°/cranial (CRA) 20°,while in 3 dogs the LAA was well visualized in the projection position of RAO 30° , and in one dog in the projection position of RAO 30°/caudal (CAU) 20°. The diameter of LAA neck was (13.6 ± 5.2) mm. The delivery sheath was safely advanced into the LAA along the pigtail catheter in all dogs, and no air embolism, thrombus or pericardial tamponade occurred. Hematoma at puncture point of groin occurred in 2 dogs, which was absorbed through pressure dressing. Macroscopic examination of the heart performed immediately after the operation showed that no bloody pericardial effusion was found, and mild hematoma at posterior wall of LA was seen in one dog and mild damage of the upper-margin intima of LAA was noted in 2 dogs. The mean fluoroscopy time was (10.1 ± 2.5) minutes and the mean operation time was (58 ± 12) minutes. TEE showed no pericardial effusion 2 weeks after the procedure. During the follow-up period of one month no sudden death, stroke or infection occurred. Conclusion This method of placing the delivery sheath into the LAA is clinically safe and effective, and it can reliably establish a pathway to advance the LAA occluder into LAA.

Purpose: C-X-C motif chemokine receptor 4 (CXCR4) and integrin αvβ6 play important roles in the malignant progression of multiple cancers. However, it remains unclear whether the expression of one or both proteins in breast cancer (BC) is of clinical significance. In this study, we investigated the expression of CXCR4 and integrin αvβ6 in BC tissues and their correlation with clinicopathological characteristics, including survival. Methods: CXCR4 and αvβ6 expression in 111 BC tissues was examined by immunocytochemistry. Correlations between the expression of the 2 proteins and patient clinicopathological characteristic were investigated using the Kaplan–Meier method and the Cox proportional hazards model. Results: CXCR4 and αvβ6 were overexpressed in BC tissue compared with normal breast tissue. Overexpression of both molecules was related to lymph node status (p = 0.013 and p = 0.022, respectively). αvβ6 overexpression was also associated with tumor size (p = 0.044). A positive correlation was detected between the expression of CXCR4 and αvβ6 (r = 0.649, p = 0.001), and co-overexpression of both molecules was associated with tumor size (p = 0.018) and lymph node metastasis (p = 0.015). Kaplan–Meier analysis revealed that overexpression of CXCR4, αvβ6, or both molecules was associated with short overall survival (OS; p < 0.001, p < 0.001, and p = 0.009, respectively) and disease-free survival (DFS; p < 0.001, p = 0.005, and p = 0.019, respectively). Multivariate analysis indicated that lymph node metastasis was an independent prognostic factor for unfavorable OS and DFS (p = 0.002 and p = 0.005, respectively), whereas co-overexpression of CXCR4 and αvβ6 was an independent prognostic factor only for OS (p = 0.043). Conclusion CXCR4 and αvβ6 may play synergistic roles in the progression of BC, and co-targeting of CXCR4 and αvβ6 could be a potential strategy for the prevention and treatment of BC.

Objective:To evaluate the clinical efficacy of intermediate frequency pulse electrical stimulation combined with TCM directional drug penetration therapy in the treatment of patients with lumbar spinal stenosis.Methods:Randomized controlled trial. Totally 90 patients with lumbar spinal stenosis who were treated between July 2018 and December 2021 in the hospital were selected according to randomized controlled trial design, and they were divided into the two groups through the random number table method, with 45 cases in each group. The control group was given non-steroidal anti-inflammatory drugs+conventional intermittent traction + intermediate frequency pulse electrical stimulation, and the combined group was treated with TCM directional drug penetration therapy on the basis of the control group. Both groups were continuously treated for 1 month. The TCM syndromes were scored before and after treatment, and Visual Analogue Scale (VAS) was used to evaluate the pain degree. Japanese Orthopedic Association (JOA) and Oswestry Disability Index (ODI) were applied to assess the dysfunction degree and quality of life, and the clinical efficacy was assessed.Results:The total effective rate was 95.56% (43/45) in combined group and was 82.22% (37/45) in control group, with statistical significance ( χ2=4.05, P=0.044). The scores of lumbago pain, articular soreness, knee soreness and weakness and impaired activity and total score in combined group after treatment were lower than those in the control group ( t=18.40, 15.81, 15.40, 26.50, 59.575, P<0.01), and the JOA score was higher than that of the control group ( t=5.62, P<0.01), while the ODI score was lower than that of the control group ( t=9.43, P<0.01). The time-point effect and between-group effect of VAS score in combined group were lower than those in the control group with the extension of time ( F=240.00, 17.19, P<0.01), and there was an interaction effect between decrease and treatment method ( F=6.66, P<0.01). Conclusion:Intermediate frequency pulse electrical stimulation combined with TCM directional drug penetration therapy is helpful to relieve the pain, improve the lumbar dysfunction degree and enhance the quality of life and clinical efficacy in patients with lumbar spinal stenosis.

Immune checkpoint inhibitors （ICIs） can activate anti-tumour-related immunity in the treatment of malignant tumours， but at the same time， they can also cause non-specific immune activation， leading to the occurrence of immune-related adverse reactions （irAEs）. It is believed that under physiological conditions， ICIs can be classified as tonic agents in traditional Chinese medicine， exerting the effect of warming yang and benefiting qi， but when the immune response become over-excited， ICIs evolve into pathogen of exuberant fire， which is destructive to the body. Combining the different periods of immunotherapy and the degree of symptoms， irAEs are divided into two phases： symptom onset phase （exuberant fire consuming qi and essence） and intermittent phase （latent fire dispersing healthy qi in critical condition）， in which yang movement is excess fire leading to toxicity of the skin and oral mucous membranes， qi constraint transforming into fire leading to toxicity of gastrointestinal tract， qi block generating fire leading to cardiotoxicity， and qi and yin deficiencies leading to fire manifesting as ICIs-related diabetes. The general principle of “simultaneous treatment of qi and fire” is proposed to guide the treatment of irAEs. During the onset phase， draining fire， directing qi downward， and dispelling drug toxicity are used to remove excess fire； raising yang， dispersing fire， and dispelling drug toxicity are used to disperse fire constraint； promoting the flow of yang and qi and dispelling drug toxicity are used to close fire and smoothen the flow； cultivating qi， clearing fire， and dispelling drug toxicity are used to disperse the deficiency fire， so as to achieve the goal of clearing exuberant fire， eliminating drug toxicity， and alleviating acute symptoms. During the intermittent phase， the aim is to generate fire slightly to warm yang qi， block latent fire， and prevent recurrence， and ultimately restore the balance of qi and yang in human physiology to prevent and treat irAEs and improve the quality of life of patients.

Objective To explore the relationship between the outpatient visits for adult asthma and air pollution in a tertiary hospital in Hefei. Methods The number of outpatient visits for asthma in a tertiary hospital in Hefei from 2014 to 2020 was collected. The air pollutant data was obtained through the Hefei Air Monitoring Station, and the meteorological indicators of the same period were collected through the China Meteorological Network. The R statistical software was used to establish a generalized additive model to analyze the lag effect of air pollution on the number of outpatient visits for asthma. Results From 2014 to 2020, there were 7 220 asthma outpatients in the tertiary hospital in Hefei, including 3104 males and 4 116 females, 3 798 patients in warm season, and 3 422 patients in cold season. During the period, the average concentrations of SO₂, NO₂, CO, O₃, PM₁₀, and PM_2.5 were 11.9μg/m³, 40.1μg/m³, 0.9 mg/m³, 87.3μg/m³, 81.3μg/m³, and 55.7μg/m³, respectively. The results of the single-pollutant model showed that every 10μg/m³ increase in SO₂ concentration increased the risk of asthma by 0.74% (95%CI: 0.22%-1.29%), and the effect was the greatest on Lag2 day. NO2 increased the risk of asthma by 0.31% (95%CI: 0.13%-0.49%), with the greatest effect on Lag0 day. The analysis of the dual pollutant model found that whereas the effect of SO₂ decreased after the incorporation of NO₂, the effect increased after the incorporation of CO, O₃, PM₁₀, or PM_2.5, respectively. The effect of NO₂ on asthma decreased after the incorporation of SO₂, whereas the effect on asthma increased after the inclusion of CO, PM₁₀, or PM_2.5. Stratified analysis of cold and warm seasons showed that the effect of NO₂ on asthma was the greatest in lag0 in cold season. The effect of SO₂ was higher in cold season than in warm season, and it was the highest in lag2. The gender stratification analysis showed that the effects of SO₂ and NO₂ on male asthma were higher than those on females. Conclusion From 2014 to 2020, the increase of SO₂ and NO₂ concentrations in Hefei is positively correlated with the risk of asthma in the outpatient department of a tertiary hospital. The effect has a certain lag. It is of great significance to formulate relevant preventive measures for the occurrence and attack of asthma.

OBJECTIVE To study the effects of Zigui yichong formula on premature ovarian insufficiency （POI） in mice through glycolysis metabolic pathway. METHODS Eighty SPF C57BL/6N female mice were divided into normal group， model group， Zigui yichong formula group （14.175 g/kg）， Zigui yichong formula+2-deoxy-D-arabino-hexose （2-DG） group （Zigui yichong formula 14.175 g/kg + glycolysis inhibitor 2-DG 100 mg/kg）， with 20 mice in each group. Except for the normal group， POI model mice were induced by intraperitoneal administration of cyclophosphamide in the other groups. After the model was successfully established， each group was given corresponding drugs. HE staining was employed to observe the pathomorphological changes in ovarian tissue and to count follicles at all developmental stages； radioimmunoassay was conducted to measure the serum levels of estradiol （E2）， anti-Müllerian hormone （AMH）， and follicle-stimulating hormone （FSH）； TUNEL assay was employed to detect apoptosis in ovarian granulosa cells of mice； the activities of hexokinase （HK）， pyruvate kinase （PK） and lactate dehydrogenase （LDH） were detected by colorimetry； Western blot and real-time fluorescence quantitative PCR were employed to analyze the protein and mRNA expressions of B-cell lymphoma-2 （Bcl-2）， Bcl-2 associated X protein （Bax）， caspase-3， HK2， pyruvate kinase M2 （PKM2）， and lactate dehydrogenase A （LDHA）. RESULTS Compared with model group， the number of primordial follicles， growing follicles， antral follicles and granulosa cells were increased significantly（P＜0.05）， and granulosa cells arranged neatly， but the number of atretic follicles and granulosa cells apoptosis were decreased significantly in Zigui yichong formula group （P＜0.05）； the serum levels of E2 and AMH， the activities of HK， PK and LDH， protein and mRNA expressions of Bcl-2， HK2， PKM2 and LDHA were increased significantly （P＜0.05）； the serum levels of FSH， the protein and mRNA expressions of Bax and caspase-3， Bax/Bcl-2 ratio were decreased significantly （P＜0.05）. 2-DG could reverse the improvement effects of Zigui yichong formula on the above indexes of POI model mice. CONCLUSIONS Zigui yichong formula may inhibit the apoptosis of ovarian granulosa cells， reduce follicle atresia and improve ovarian reserve function by promoting glycolysis levels in POI model mice.
