Research progress on effects of air pollution on pollinosis and its mechanisms / 环境与职业医学

Pollinosis is one of the common allergic diseases, and its morbidity continues to increase. Studies have demonstrated that air pollution is a key environmental factor that leads to the increased prevalence of pollinosis. Air pollutants and pollen allergens exert synergistic effects in stimulating allergic responses in susceptible individuals. In this article, we analyzed the relationship between air pollution and pollinosis based on the latest studies, and elaborated potential mechanisms on how air pollution increases the incidence of pollinosis and aggravates allergic reactions. Air pollutants can increase both pollen production and the levels of allergenic proteins, and enhance allergenicity of pollen allergens through structural alterations or chemical modifications. The potential mechanisms of air pollutants exacerbating pollen allergies are as follows: Air pollutants may disrupt the barrier function of the respiratory epithelium and facilitate the penetration of pollen allergens into deeper tissues. Additionally, they may accelerate the process of the release of pollen allergy-related cytokines, promoting T helper 2 (Th2) cell differentiation and exacerbating inflammatory responses in the airways. Given the limitations of existing research, future prospective studies are needed to explore the effects of mixed pollutants and different types of pollutants on pollen, and the response mechanisms of allergy-related cells and cytokines to different pollutant categories. The findings would provide a comprehensive understanding of the impacts of air pollution on pollen allergies and scientific evidence for effective protection of the heath of pollinosis patients.

Pharmaceutical care of reactivating anthracycline chemotherapy in a patient with advanced breast cancer combined with thyroid cancer / 中国药房

OBJECTIVE To explore the pharmaceutical care of reactivating anthracycline chemotherapy in patients with advanced breast cancer complicated with thyroid cancer. METHODS Clinical pharmacists participated in the whole treatment process of a patient with advanced breast cancer complicated with thyroid cancer and provided personalized medication recommendations. Considering that the patient currently has multiple primary anti-tumor drug resistance， clinical pharmacists recommend reactivating the EC rescue protocol （intravenous infusion of epirubicin hydrochloride 140 mg+cyclophosphamide 1 g， d1， 21 days for a cycle）. The cumulative lifetime dose of epirubicin and the optimal course of chemotherapy was estimated according to the body weight change of the patient. Given the issue that abnormal fluctuation of thyroid stimulating hormone （TSH） level during chemotherapy may increase the risk of cardiac toxicity， clinical pharmacists suggest adopting a dose adjustment strategy of “fast first and slow later” for Levothyroxine sodium tablet according to the target range of TSH and test results. RESULTS The doctors adopted the pharmacists’ suggestion； the clinical pharmacists assisted the doctors in reactivating the anthracycline-based 7-cycle combination regimen， during which the patient had no significant cardiac adverse events and was repeatedly evaluated as stable. TSH decreased steadily after Levothyroxine sodium tablets were added， and no adverse reaction related to TSH inhibition was observed. CONCLUSIONS Patients with primary drug-resistant breast cancer complicated with thyroid cancer may be reactived anthracyclines if necessary， but baseline cardiac function and thyroid hormone levels should be tested before initiation， and cardiac toxicity risk assessment should be performed in combination with the patient’s history. Clinical pharmacists should actively exert their professional advantages to carry out whole-process pharmaceutical care for such patients， so as to ensure the safety of drug use for patients.

Imaging classification and analysis of the diagnosis and treatment of infected pancreatic necrosis:a report of 126 cases / 中华外科杂志

Objective: To explore the clinical characteristics of various types of infected pancreatic necrosis(IPN) and the prognosis of different treatment methods in the imaging classification of IPN proposed. Methods: The clinical data of 126 patients with IPN admitted to the Department of Pancreatic and Biliary Surgery, the First Affiliated Hospital of Harbin Medical University from December 2018 to December 2021 were analyzed retrospectively. There were 70 males(55.6%) and 56 females(44.4%), with age(M(IQR)) of 44(17)years (range: 12 to 87 years). There were 67 cases(53.2%) of severe acute pancreatitis and 59 cases (46.8%) of moderately severe acute pancreatitis. All cases were based on the diagnostic criteria of IPN. All cases were divided into Type Ⅰ(central IPN)(n=21), Type Ⅱ(peripheral IPN)(n=23), Type Ⅲ(mixed IPN)(n=74) and Type Ⅳ(isolated IPN)(n=8) according to the different sites of infection and necrosis on CT.According to different treatment strategies,they were divided into Step-up group(n=109) and Step-jump group(n=17). The clinical indicators and prognosis of each group were observed and analyzed by ANOVA,t-test,χ2 test or Fisher exact test,respectively. Results: There was no significant difference in mortality, complication rate and complication grade in each type of IPN(all P>0.05). Compared with other types of patients, the length of stay (69(40)days vs. 19(19)days) and hospitalization expenses(323 000(419 000)yuan vs. 60 000(78 000)yuan) were significantly increased in Type Ⅳ IPN(Z=-4.041, -3.972; both P<0.01). The incidence of postoperative residual infection of Type Ⅳ IPN was significantly higher than that of other types (χ2=16.350,P<0.01). There was no significant difference in the mortality of patients with different types of IPN between different treatment groups. The length of stay and hospitalization expenses of patients in the Step-up group were significantly less than those in the Step-jump group(19(20)days vs. 33(35)days, Z=-2.052, P=0.040;59 000(80 000)yuan vs. 122 000(109 000)yuan,Z=-2.317,P=0.020). Among the patients in Type Ⅳ IPN, the hospitalization expenses of Step-up group was significantly higher than that of Step-jump group(330 000(578 000)yuan vs. 141 000 yuan,Z=-2.000,P=0.046). The incidence of postoperative residual infection of Step-up group(17.4%(19/109)) was significantly lower than that of Step-jump group(10/17)(χ2=11.980, P=0.001). Conclusions: Type Ⅳ IPN is more serious than the other three types. It causes longer length of stay and more hospitalization expenses. The step-up approach is safe and effective in the treatment of IPN. However, for infected lesions which are deep in place,difficult to reach by conventional drainage methods, or mainly exhibit "dry necrosis", choosing the step-jump approach is a more positive choice.

OBJECTIVE@#To analyze the effect of local unstable atherosclerotic plaque on plaque formation in the carotid and aortic arteries of rabbits.@*METHODS@#Thirty New Zealand white rabbits were randomly divided into atherosclerosis model group, highfat diet feeding group, and normal chow feeding group (blank control group). In the model group, carotid artery balloon injury was induced after 4 weeks of high-fat diet feeding. Eight weeks later, all the rabbits were euthanized for histopathological examination of the carotid artery and abdominal aorta, and the mean intimal thickness and plaque to lumen area ratio were measured using image analysis software. Venous blood samples were collected from the rabbits for blood lipid analysis.@*RESULT@#At the ends of 4, 8 and 12 weeks, the rabbits in the model group and high-fat feeding group, but not those in the blank control group, all showed significant weight gain compared with their body weight at 0 week (P < 0.05). The mean intimal thickness was significantly greater in atherosclerosis model group than in the other two groups (P < 0.05). In atherosclerosis model group, the mean intimal thickness and plaque to lumen area ratio in the injured carotid artery were significantly greater than those in the contralateral carotid artery and abdominal aorta (P < 0.05). At the end of the 12 weeks, the levels of triglyceride (TG), total cholesterol (TC), low-density cholesterol (LDL-C), high-density cholesterol (HDL-C) and highsensitivity C-reactive protein (CRP) were all significantly higher in the model group and high-fat feeding group than in the blank control group (P < 0.05); the levels of TG, TC, LDL-C, or HDL-C did not differ significantly between the model group and high-fat feeding group (P>0.05), but the level of CRP was significantly higher in arteriosclerosis model group (P < 0.05).@*CONCLUSION@#Local unstable atherosclerotic plaque can increase the level of CRP and promote the formation of atherosclerotic plaques in the carotid artery and abdominal aorta in rabbits.

Evolution and progress of surgical intervention strategies for acute pancreatitis / 中华外科杂志

Acute pancreatitis is one of the common surgical acute abdominal diseases. Since people first recognized acute pancreatitis in the middle of the nineteenth century, a diversified minimally invasive treatment model with standardization has been formed today. According to the main line of surgical intervention of acute pancreatitis treatment,this period can be roughly divided into five stages:exploration stage, conservative treatment stage, pancreatectomy stage, debridement and drainage of the pancreatic necrotic tissue stage, and minimally invasive treatment as the first choice led by the multidisciplinary team mode stage. Throughout history, the evolution and progress of surgical intervention strategies for acute pancreatitis cannot be separated from the progress of science and technology, the update of treatment concepts and the further understanding of the pathogenesis. This article will summarize the surgical characteristics of acute pancreatitis treatment at each stage to explain the development of surgical treatment of acute pancreatitis,to help investigate the development of surgical treatment of acute pancreatitis in the future.

Analysis of clinical efficacy and risk factors of relapse in young patients with cervical instability treated by manipulation / 中国骨伤

OBJECTIVE@#To determine the clinical efficacy of different manipulation in the treatment of cervical instability in young people, and to analyze the risk factors of relapse of cervical instability in young people.@*METHODS@#From March 2021 to June 2022, the clinical data of 120 young patients with cervical instability were retrospectively analyzed. According to the different treatment methods, they were divided into rotation group (60 cases, 3 cases of loss) and tendon group (60 cases, 5 cases of loss). There were 25 males and 32 females in rotation-traction manipulation group;age ranged from 22 to 44 years old with a median of 28 years old;course of disease ranged from 0.17 to 120 months with amedian of 22 months. There were 22 males and 33 females in tendon-regulating manipulation group;age ranged from 21 to 42 years old with a median of 27 years old;course of disease ranged from 0.23 to 180 months with a median of 24 months. Both groups were treated for 2 weeks, once every other day for 7 times, and were followed up for 1 year. The clinical efficacy of the two groups was evaluated, and the visual analogue scale (VAS), neck disability index (NDI) were observed before and after treatment. One year after the course of treatment, patients with effective treatment were followed up to make statistics on recurrence. Patients with recurrence were included in the recurrence group, while those without recurrence were included in the non-recurrence group. Factors that may affect symptom recurrence were analyzed, and univariate and multivariate Logistic regression analysis were performed.@*RESULTS@#The 13 patients who failed the treatment (4 cases in the rotation-traction manipulation group and 9 cases in the tendon-regulating manipulation group) were not followed up. All the 99 patients who were effective in treatment were followed up ranged from 303 to 406 days with a median of 359 days. No complications occurred in all patients. There were significant differences in VAS and NDI between the two groups after treatment and before treatment (P<0.05), and there were significant differences in VAS and NDI between the two groups after treatment (P<0.05). Ninety-nine patients achieved follow-up, 56 (56.57%) relapsed and 43 (43.43%) did not. Univariate correlation analysis showed that NDI index, the time spent at the desk every day, the time spent using electronic products every day and angular displacement of anterior flexion before treatment in the relapse group were significantly higher than those in the non-relapse group (P<0.05). Logistic regression analysis showed that the time spent at the desk every day [OR=2.447, 95%CI(1.255, 4.771)], the time spent using electronic products every day [OR=1.892, 95%CI(1.066, 3.358)] and the angular displacement of anterior flexion of the cervical before treatment [OR=1.246, 95%CI(1.045, 1.485) ]were the risk factors for relapse.@*CONCLUSION@#Both rotation-traction manipulation and tendon-regulating manipulation can effectively treat cervical instability in young people, and rotation-traction manipulation has more advantages than tendon-regulating manipulation in improving cervical pain and cervical dysfunction in patients. The time spent at the desk every day, the time spent using electronic products every day, and the increase of cervical flexion angle displacement will increase the risk of relapse in patients.

Objective:To investigate the magnetic resonance imaging (MRI) characteristics and pathological imaging findings of primary hepatic angiosarcoma (PHA).Methods:A retrospective analysis was conducted on the clinical, pathological and MRI data of 15 cases of PHA confirmed by pathology at the Affiliated Zhongshan Hospital of Fudan University from October 2011 to August 2022, including 9 males and 6 females, aged (57.4±11.5) years old. The MRI data included the number, location, size, morphology, signal intensity on non-contrast MRI, enhancement features, and apparent diffusion coefficient (ADC) values of the lesions were collected.Results:Among the 15 cases, 4 presented as dominant masses, 10 as multiple nodules, and 1 as diffuse small nodule type. Among the 15 patients, 11(73.3%) had multiple lesions, all involving the left and right lobes of the liver. The size of the lesion varies from punctate to 13.5 cm. A total of 24 lumpy lesions and 53 nodular lesions were analyzed. Among the 24 lumpy lesions, 14 were irregular. Among the 53 nodular lesions, 28 were quasi circular and 25 were irregular. Compared to nodular lesions, the signal of lumpy lesions is uneven, with varying degrees of necrotic areas visible in 100% (24/24) and bleeding in 91.7% (22/24) of the cases. The arterial phase enhancement of 24 lumpy lesions was mainly characterized by central cord, grid like enhancement with or without peripheral points, lines, and incomplete ring enhancement (66.7%, 16/24). The arterial phase of 53 nodular lesions mainly showed circular and overall enhancement (64.2%, 34/53), while during the portal vein, continuous circular enhancement, centripetal or grid filling and complete enhancement were observed. After removing some small lesions or artifact interference, 55 lesions were measured, and the ADC value of the lesions was (1.57±0.54)×10 -3 mm 2/s, the ADC of adjacent liver parenchyma in the same layer was (1.36±0.30)×10 -3 mm 2/s, the difference between the two was statistically significant ( P=0.012). Conclusions:The MRI manifestations of PHA patients have certain characteristics, especially the discovery of vascular perforation and malformation within the lesion. Combined with clinical and laboratory examinations, it is helpful for the diagnosis of the disease.

A proposed mechanism by which Qishen Yiqi dropping pill improves cardiac energy metabolism in rats with heart failure based on metabolomics and network pharmacology / 药学学报

"Omics" and bioinformatics have brought new ideas to the study of traditional Chinese medicine. This study used metabonomics and network pharmacology to investigate the pharmacodynamic basis and regulation of Qishen Yiqi dropping pill (QDP) improving cardiac energy metabolism in rats with heart failure (HF). 1H NMR metabonomics analysis showed that eight metabolites, including carnitine, glutamine, creatine, proline, homocitrulline, lactic acid, taurine and alanine appeared significant callback after QDP treatment for HF. The results indicate that QDP regulates the metabolism of carbohydrate, lipid, ATP and protein. The animal experiment was conducted in accordance with the regulations of the Ethics Committee for Experimental Animal Management and Animal Welfare of Institute of Materia Medica, Chinese Academy of Medical Sciences. A "drug-component-target-disease" network was established using network pharmacology, and the "component-target" sub-network related to the above energy metabolism processes was extracted by combining metabonomics results. Results revealed 79 chemical compounds and 47 potential targets of QDP involved in the regulation of energy metabolism, and identified key chemical components including ursolic acid, notoginsenoside G, ginsenoside-Rh1, and core targets such as INS, PPARG, and AKT1. The results also demonstrated the complex multi-target and multi-component relationship between QDP and HF from the perspective of energy metabolism. The molecular docking technique verified a strong interaction between some targets and chemical compounds, with affinities less than -5 kcal·mol-1. The results of this study provide useful information for the clinical application, development, and utilization of QDP.

Expert consensus on clinical application of GBE50 Dispersible Tablets for ischemic cardiovascular and cerebrovascular diseases / 中国中药杂志

Ginkgo biloba Extract( GBE50) Dispersible Tablets is a new standardized prescription,which is widely used in the treatment of ischemic cardiovascular and cerebrovascular diseases. However,there are still many problems in its clinical application.Rational and safe use of GBE50 Dispersible Tablets is pivotal to the medication safety and clinical prognosis of patients. This consensus has been jointly formulated by clinical experts of traditional Chinese medicine and western medicine in cardiovascular and cerebrovascular diseases and followed the Manual for the Clinical Experts Consensus of Chinese Patent Medicine published by the China Association of Chinese Medicine. The present study identified clinical problems based on clinical investigation,searched the research papers according to PICO clinical problems,carried out evidence evaluation,classification,and recommendation by GRADE system,and reached the expert consensus with nominal group technique. The consensus combines evidence with expert experience. Sufficient evidence of clinical problems corresponds to " recommendations",while insufficient evidence to " suggestions". Safety issues of GBE50 Dispersible Tablets,such as indications,usage and dosage,and medication for special populations,are defined to improve clinical efficacy,promote rational medication,and reduce drug risks. This consensus needs to be revised based on emerging clinical issues and evidencebased updates in practical applications in the future.

Clinical symptoms and imaging findings of cervical instability in young adult / 中国骨伤

OBJECTIVE@#To explore clinical symptoms and X-ray imaging features of cervical instability in young adult represented by postgraduates with a master's degree in medicine.@*METHODS@#Totally 91 postgraduates with a master's degree in medicine were investigated from September to December 2021, including 45 males and 46 females;aged from 22 to 30 years old with an average of (25.30±2.18) years old. The cervical spondylosis-related discomfort symptoms of the subjects were collected and examined by the examiner for neck and shoulder tenderness point examination and cervical vertebra positive and lateral and functional X-ray radiography. According to the results of X-ray examination, the subjects were divided into stable cervical group and unstable cervical group.@*RESULTS@#Among 91 subjects, there were 50 patients with cervical instability, accounting for 54.90% of total number of subjects. The cervical curvature was abnormal in 78 patients, accounting for 85.70% of total number of subjects. Among 50 patients with cervical instability, 50 patients were diagnosed as cervical instability on the basis of angular displaxement(AD)≥ 11 °, including 13 cases of C3,4 instability, 30 cases of C4,5 instability and 7 cases of C5,6 instability;and 5 cases were diagnosed as cervical instability based on horizontal displacement(HD)≥ 3.5 mm, including 1 case of C3,4 instability and 4 cases of C4,5 instability. Compared with stable cervical group, the number of discomfort symptoms of neck pain, headache and shoulder pain in instability group was significantly higher than that of in stable cervical group(P<0.05);and the number of tenderness in spinous process space of C4,5 and C5,6, 2 cm adjacent to the spinous process of C2-C5 and the superior angle of the scapula (the stop point of levator scapulae) in the instability group was significantly higher than that in the stable cervical group (P<0.05);and the cervical curvature in the instability group was significantly lower than that in stable cervical group(P<0.05).@*CONCLUSION@#The incidence of cervical instability in young adult represented by postgraduates with a master's degree in medicine is high, they are mainly diagnosed as cervical instability on the basis of vertebral angular displacement ≥ 11°, and the instability segments are concentrated on C3,4, C4,5 and C5,6 segments, the occurrence of cervical instability is often accompanied by abnormalities of cervical curvature. Most of clinical manifestations are head, neck and shoulder pain, especially neck pain in unstable segment.
