Idiopathic pulmonary fibrosis （IPF）， as a progressive lung disease， has a poor prognosis and no reliable and effective therapies. IPF is mainly treated by organ transplantation and administration of chemical drugs， which are ineffective and induce side effects， failing to meet the clinical needs. Therefore， developing safer and more effective drugs has become an urgent task， which necessitates clear understanding of the pathogenesis of IPF. The available studies about the pathogenesis of IPF mainly focus on macrophage polarization， epithelial-mesenchymal transition （EMT）， oxidative stress， and autophagy， while few studies systematically explain the principles and links of the pathogeneses. According to the traditional Chinese medicine theory， Qi deficiency and blood stasis and Qi-Yang deficiency are the key pathogeneses of IPF. Therefore， the Chinese medicines or compound prescriptions with the effects of replenishing Qi and activating blood， warming Yang and tonifying Qi， and eliminating stasis and resolving phlegm are often used to treat IPF. Modern pharmacological studies have shown that such medicines play a positive role in inhibiting macrophage polarization， restoring redox balance， inhibiting EMT， and regulating cell autophagy. However， few studies report how Chinese medicines regulate the pathways in the treatment of IPF. By reviewing the latest articles in this field， we elaborate on the pathogenesis of IPF and provide a comprehensive overview of the mechanism of the active ingredients or compound prescriptions of Chinese medicines in regulating IPF. Combining the pathogenesis of IPF with the modulating effects of Chinese medicines， we focus on exploring systemic treatment options for IPF， with a view to providing new ideas for the in-depth study of IPF and the research and development of related drugs.

Oral squamous cell carcinoma (OSCC) is the most common oral malignancy. It has a high incidence, strong invasion ability, easy metastasis, poor curative effect, and poor prognosis. Innate lymphoid cells (ILCs) are an important part of immune cells located in the mucosal barrier, which play an important role in the occurrence, development and outcome of tumors. ILCs are the key cells for decoding the regulatory mechanism of tumor microenvironment and the signatures for tumor progression. This paper reviewed the latest progress on ILCs, summarized the possible characteristics and functions of ILCs in the microenvironment of OSCC, and explored the relationship between ILCs and the occurrence, development and immunotherapy of OSCC.

Objective:To analyze and predict the future trend of the premature mortality of major chronic and non-communicable diseases in Anhui Province, evaluate the implementation of the "Healthy China 2030" Plan, and explore its influencing factors.Methods:Using data from death-cause surveillance and statistical yearbooks in Anhui, the trend prediction and analysis on influencing factors were conducted by using methods such as time series accumulation and logarithmic linear Joinpoint regression, principal component regression.Results:In Anhui, 28.10% of the deaths were premature ones, of which 84.40% were attributed to chronic and non-communicable diseases. In premature deaths attributed to chronic and non-communicable diseases, the deaths caused by malignant tumor and cardiovascular disease accounted for 45.88% and 41.65% respectively. The prediction results showed that the premature mortality of major chronic and non-communicable diseases would decrease in Anhui in the future, and by 2030, the goal in the "Healthy China 2030" Plan would be reached only in rural area. To reduce premature death, it is necessary to pay attention to the prevention and control of malignant tumor and cardiovascular disease. Men in urban area are the key population. Factors that reflect urban infrastructure had a significant impact on premature mortality of major chronic non-communicable diseases, such as garden and green space area per capita. Factors such as concentration of PM 2.5 had a negative impact on premature mortality of chronic non-communicable diseases, while factors such as garden and green space area per capita had a positive impact. Conclusions:Disease burden caused by chronic and non-communicable diseases, such as malignant tumor, exits in Anhui. Men in urban area are key population in the prevention and control of chronic and non-communicable diseases in the future.

Atmospheric particulate matter has an association with respiratory system inflammation, and low molecular weight hyaluronic acid (LMW-HA) is a key biomarker of inflammatory cascade reaction. This review summarized the possible pathways and biomarkers of atmospheric particulate matter causing respiratory system inflammation through high molecular weight hyaluronic acid (HMW-HA)/LMW-HA imbalance, including the synthesis and decomposition of HA, the reduction of particulate matter and HMW-HA, the increase of LMW-HA, and the relationship between LMW-HA and respiratory system inflammation. Furthermore, inhibitors and therapeutic drugs targeting certain biomarkers were further listed. This review could shed light on the mechanism of respiratory system inflammation caused by atmospheric particulate matter and the weak points that need attention in subsequent research.

Objective To investigate the high-frequency ultrasonic anatomical features of the adjacent C7 transverse process and its clinical value in stellate ganglion block(SGB).Methods High-frequency ultrasound was applied to obtain ultrasonographic anatomical sonogram features in the plane of bilateral C7 transverse processes in 52 cases(104 sides in total)of healthy adults and then stored for the operator to learn and correctly label each tissue structure.Fifty patients who underwent ultrasound-guided SGB were selected and divided into the BC7 group(25 cases before study)and AC7 group(25 cases after study).The operation time,SGB success rate,number of adjusted needle tips,dosage of anaesthetic and adverse reaction of patients in both group were recorded.Results The main muscles observed in the C7 plane were the longissimus and anterior scalene muscles,the ultrasonographic anatomical relationships of the vagus nerve located in the carotid sheath,the pleura located posterior to the subclavian artery,and the recurrent laryngeal nerve located in the vicinity of the branches of the inferior thyroid artery are described,and the stellate ganglion was illustrated as a flattened hypoechogenic structure visible on the deep surface of the prevertebral fascia in the region of the external cervical longissimus muscle,vertebral artery and vein,and the medial aspect of the anterior oblique muscle,and emanated the sonographic features of several hypoechoic nerve bundles.Ultrasound guided SGB was completed uneventfully in patients of both groups,and all patients developed Horner syndrome,with the SGB success rate of 100%.The operation time[(5.36±1.11)minutes]of patients in the BC7 group was longer than that in the AC7 group[(3.08±0.86)minutes],the number of adjusted needle tips[(4.20±1.00)times]of patients in the BC7 group was more than that in the AC7 group[(2.24±0.87)times],and the dosage of anaesthetic[(1.82±0.28)mL]of patients in the BC7 group was more than that in the AC7 group[(1.64±0.22)mL],all the differences were statistically significant(P<0.05).There was no significant difference in the incidence of adverse reaction between the two groups(P>0.05).Conclusion After ultrasonic learning of adjacent structures through C7 transverse process,SGB is safe and easy to perform.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To explore the prognostic prediction value of quantitative digital subtraction angiography (DSA) parameters in patients with acute anterior circulation ischemic stroke undergoing mechanical thrombectomy, and whether the clinical values vary by stroke etiology.Methods:This study was a post hoc analysis of the Multicenter Prospective Captor Trial. Patients with acute anterior circulation large-vessel occlusion and successful recanalization from April 2018 to July 2019 were screened. Post-processing analysis was performed on the DSA imaging sequence after recanalization, and 4 regions of interest (ROI) were selected in the target vessel: ROI1 (the proximal of the internal carotid artery-C2 segment), ROI2 (the starting point of the internal carotid artery-C7 segment), ROI3 (the end of the middle cerebral artery-M1 segment), and ROI4 (the end of the middle cerebral artery-M2 segment). Time to peak (TTP) was defined as the time at contrast concentration of selected ROI reached its maximum. Relative TTP (rTTP) was calculated by subtracting the TTP of ROI1 from the TTP of distalis ROIs. Successful recanalization was defined as modified Thrombolysis In Cerebral Infarction (mTICI) grade≥2b. Favorable outcomes at 3 months were defined as the modified Rankin Scale score≤2. According to the modified Rankin Scale score, the patients were divided into good prognosis group and poor prognosis group. The differences in clinical characteristics, postoperative hemodynamic parameters, and other data were compared between patients with good and poor prognoses. Univariate and multivariate Logistic regression was used to analyze factors related to a good prognosis. Finally, the prognostic prediction value of hemodynamic parameters was analyzed in patients with different Trial of Org10172 in Acute Stroke Treatment etiological classifications.Results:A total of 245 patients were collected, of which 161 patients [age 69 (60, 76) years, 92 (57.1%) male] were finally included in the analysis, including 36 cases of large artery atherosclerosis (LAA) stroke, 76 cases of cardiogenic embolism (CE), and 49 cases of other causes of stroke. Seventy-one (44.1%) patients had favorable outcomes at 3 months. The post-operative hemodynamic analysis indicated that patients with favorable outcomes ( n=71) had a higher proportion of mTICI grade 3 [54/71 (76.1%) vs 41/90 (45.6%),χ 2=15.26, P<0.001] and lower rTTP 31 [means TTP ROI3-TTP ROI1;0.33 (0.23, 0.54) s vs 0.47 (0.31, 0.65) s, Z=-2.71, P=0.007] than patients with unfavorable outcomes ( n=90). The mTICI score and rTTP 31 were respectively included in multivariate Logistic regression models. It was shown that mTICI grade 3 (adjusted OR=5.97, 95% CI 2.49-14.27, P<0.001) and rTTP 31 (adjusted OR=0.24, 95% CI 0.06-0.99, P=0.048) were significantly associated with favorable outcomes, and the area under the receiver operating characteristic curve of the models had no statistically significant difference ( P=0.170). Subgroup analysis showed that rTTP 31 was significantly associated with the prognosis of patients with LAA stroke ( OR=0, 95% CI 0-0.25, P=0.014), while mTICI grade was associated with the prognosis of patients with CE ( OR=3.91, 95% CI 1.40-10.91, P=0.009) and other etiologies ( OR=7.35, 95% CI 1.92-28.14, P=0.004). Conclusions:In patients with acute anterior circulation ischemic stroke and successful recanalization, both mTICI score and rTTP 31 had significant predictive value for favorable outcomes at 3 months. Moreover, rTTP 31 was significantly associated with the prognosis of patients with LAA stroke, while mTICI score was significantly related to the prognosis of patients with CE and other causes of stroke.

【Objective】 To analyze the data of clinical blood transfusion quality control supervision in Shanghai, so as to provide reference for the improvement of clinical blood transfusion quality management in hospitals at all levels. 【Methods】 The data of clinical blood transfusion quality control supervision in hospitals at all levels from 2016 to 2021 were retrospectively analyzed to obtain the characteristics and indicators in the quality management. 【Results】 The overall level of clinical blood transfusion quality management in Shanghai steadily improved from 2016 to 2021 (F=3.82, P<0.01), and the management level of different hospitals varied significantly (F=9.00, P<0.01). In 2021, the full compliance rates of housing facilities, instruments and equipment, diagnostic reports and medical record writing among the third-level indicators of clinical blood transfusion quality management in hospitals at all levels were as follows: 86.49%(32/37), 100% (37/37)and 43.24%(16/37) for tertiary comprehensive hospitals; 61.11%(11/18), 88.89%(16/18) and 50.00% (9/18)for tertiary specialized hospitals; 60.87%(14/23), 78.26%(18/23)and 47.83%(11/23) for secondary comprehensive hospitals, ; 60.00%(9/15), 66.67%(10/15), 40.00%(6/15) for secondary specialized hospitals; 52.38%(11/21), 38.10%(8/21), 42.86%(9/21) for private hospitals. 【Conclusion】 The characteristics of clinical blood transfusion quality management in hospitals at all levels in Shanghai differed significantly, with different strengths and weaknesses. Hospitals should improve blood transfusion management in terms of housing facilities, personnel management, system process as well as diagnostic reports and medical record writing, in order to enhance the clinical blood transfusion quality management.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.
