OBJECTIVE To introduce a case of interstitial pneumonia induced by vedolizumab （VDZ）， summarize and analyze the characteristics of the occurrence of VDZ-associated lung toxicity， and provide a reference for the clinically safe use of drugs. METHODS From the perspective of clinical pharmacists， the diagnosis and treatment of a case of VDZ-induced interstitial pneumonia were retrospectively analyzed， and the association of adverse drug reactions （ADR） was analyzed. Retrieving from Chinese and English databases such as CNKI， VIP， PubMed and Web of Science， case reports of VDZ-associated lung toxicity were summarized and analyzed. RESULTS The patient developed interstitial pneumonia during the use of VDZ and empirical anti- infective therapy with antibiotics was ineffective. After withdrawal of VDZ and treatment with methylprednisolone， symptoms and imaging examinations improved， but interstitial pneumonia still existed. According to Naranjo’s ADR evaluation scale and based on China Adverse Drug Reaction Reporting and Monitoring Manual， the association between VDZ and interstitial pneumonia was “very likely”. Results of the literature analysis showed that among 29 involved patients （including the patient reported in this article）， there were 19 males and 10 females， with an average age of （49.24±17.06） years. Lung toxicity mainly included VDZ- associated pneumonia， eosinophilic pneumonia， pulmonary granulomas or necrobiotic nodules， interstitial lung injury， etc.， which mostly occurred ≤24 weeks after medication （58.62%）. The main clinical manifestations included cough， dyspnea and fever. The vast majority of patients improved or recovered after drug withdrawal and/or glucocorticoid treatment， but one patient died of respiratory failure. CONCLUSIONS Lung toxicity is a rare ADR of VDZ with insidious onset and nonspecific symptoms. Once patients experience symptoms such as cough and dyspnea， early diagnosis，timely drug withdrawal，and symptomatic treatment measures such as glucocorticoid should be taken to ensure medication safety.

The application of function-preserving pancreatic surgery as a restrictive resection technique is primarily targeted towards benign or those with borderline or low-grade lesions. This approach has been shown to significantly improve both short-term and long-term quality of life outcomes for patients following surgical intervention. In comparison to conventional laparoscopic procedures, robotic surgical systems have demonstrated superior efficacy and precision when employed in pancreas surgeries, and the safety and reliability are widely recognized within the medical community. Nevertheless, there remains a dearth of research investigating the specific appli-cations of robotic-assisted function-preserving pancreatic surgery. Consequently, the authors compre-hensive review the latest progress on robot-assisted function-preserving pancreatic surgery, while highlighting of surgical scope, techniques utilized during these procedures as well as associated prognostic considerations.

Objective:To analyze the relationship between genotype and clinical phenotype of the MYH7-R453C mutation in five Chinese hypertrophic cardiomyopathy (HCM) families.Methods:A retrospective cohort study was conducted on 527 unrelated HCM probands who were first diagnosed at the First Affiliated Hospital of Air Force Medical University (Xijing Hospital) from February 2014 to July 2018, and the high-throughput whole exome targeted sequencing of 96 genes related to hereditary cardiovascular disease was performed on the probands. The probands carrying the MYH7-R453C mutation were screened out, and their family members carrying the mutation were verified using Sanger sequencing. Healthy individuals without family history of genetic diseases from the same period and ethnicity were recruited as controls. Clinical data such as echocardiography, 12-lead electrocardiogram, and cardiac magnetic resonance imaging of the probands and their family members were collected, and the correlation between patient genotype and clinical phenotype was analyzed. Endpoint or key events were recorded through hospital re-examination or telephone follow-up.Results:The MYH7-R453C mutation was detected in 5 HCM probands, and clinical data and genetic results of 20 family members, including probands, were collected. Among them, 13 carried the MYH7-R453C mutation, of which 12 were diagnosed with HCM, and one child (F1Ⅲ 5) experienced early changes of HCM. The seven family members who did not carry the MYH7-R453C mutation had normal echocardiograms and 12-lead electrocardiograms. Among the 12 patients diagnosed with HCM, 2 experienced (F2Ⅱ 7, F5Ⅰ 2) sudden cardiac death, 2 experienced (F1Ⅲ 1, F3Ⅲ 3) events of sudden cardiac death survival, 2(F1Ⅱ 2, F3Ⅱ 1) died from heart failure during the follow-up period. Combined with the initial visit and follow-up, 4 families (F1, F2, F3, F5) had a family history of sudden death, among which 3 families probands or multiple family members experiencing sudden death before the age of 30 and adverse outcomes such as implantation of implantable cardioverter-defibrillators after sudden death survival. Conclusions:In the five families with HCM carrying MYH7-R453C mutations, genotype is highly correlated with clinical phenotype, and patients have a high risk of sudden death and poor prognosis. Early diagnosis of individuals carrying the MYH7-R453C gene mutation, both within the patient′s family and in the patients themselves, is crucial for initiating early treatment, preventing sudden death, and assessing prognosis.

OBJECTIVE: Evidence that long-term exposure to ambient air pollution increases mortality among older adults, particularly those residing in low-level air pollution locations, remains scarce. This study investigated the potential links between long-term low-level air pollution exposure and mortality among Chinese older adults. METHODS: A population-based study with 317,464 individuals aged ≥ 65 years was conducted in Shenzhen, China during 2018 and 2020. Logistic regression models were used to analyze the associations between long-term exposure to air pollution and all-cause mortality, as the primary outcome, as well as non-accidental, cancer and cardiovascular mortality. RESULTS: Significant associations of PM ₁, PM _2.5, PM ₁₀, SO ₂, CO, and O ₃ exposures with a higher risk of all-cause mortality were found. Adjusted odds ratio ( OR) for each 1 µg/m ³ increment was 1.49 [95% confidence interval ( CI): 1.46, 1.53] for PM ₁, 1.30 (1.27, 1.32) for PM _2.5, 1.05 (1.04, 1.06) for PM ₁₀, 5.84 (5.39, 6.32) for SO ₂, 1.04 (1.04, 1.05) for CO, and 1.02 (1.00, 1.03) for O ₃, respectively. Long-term PM ₁, PM _2.5, PM ₁₀, SO ₂, and CO exposures also elevated the risks of non-accidental, cancer and cardiovascular mortality. CONCLUSION Long-term low-level air pollution exposure was associated with an increased mortality risk among Chinese older adults.

BACKGROUND: Weather conditions are a possible contributing factor to age-related macular degeneration (AMD), a leading cause of irreversible loss of vision. The present study evaluated the joint effects of meteorological factors and fine particulate matter (PM_2.5) on AMD. METHODS: Data was extracted from a national cross-sectional survey conducted across 10 provinces in rural China. A total of 36,081 participants aged 40 and older were recruited. AMD was diagnosed clinically by slit-lamp ophthalmoscopy, fundus photography, and spectral domain optical coherence tomography (OCT). Meteorological data were calculated by European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis and were matched to participants' home addresses by latitude and longitude. Participants' individual PM_2.5 exposure concentrations were calculated by a satellite-based model at a 1-km resolution level. Multivariable-adjusted logistic regression models paired with interaction analysis were performed to investigate the joint effects of meteorological factors and PM_2.5 on AMD. RESULTS: The prevalence of AMD in the study population was 2.6% (95% CI 2.42-2.76%). The average annual PM_2.5 level during the study period was 63.1 ± 15.3 µg/m³. A significant positive association was detected between AMD and PM_2.5 level, temperature (T), and relative humidity (RH), in both the independent and the combined effect models. For PM_2.5, compared with the lowest quartile, the odds ratios (ORs) with 95% confidence intervals (CIs) across increasing quartiles were 0.828 (0.674,1.018), 1.105 (0.799,1.528), and 2.602 (1.516,4.468). Positive associations were observed between AMD and temperature, with ORs (95% CI) of 1.625 (1.059,2.494), 1.619 (1.026,2.553), and 3.276 (1.841,5.830), across increasing quartiles. In the interaction analysis, the estimated relative excess risk due to interaction (RERI) and the attributable proportion (AP) for combined atmospheric pressure and PM_2.5 was 0.864 (0.586,1.141) and 1.180 (0.768,1.592), respectively, indicating a synergistic effect between PM_2.5 and atmospheric pressure. CONCLUSIONS This study is among the first to characterize the coordinated effects of meteorological factors and PM_2.5 on AMD. The findings warrant further investigation to elucidate the relationship between ambient environment and AMD.

Objective:To summarize the clinical characteristics of patients with Guillain-Barré syndrome (GBS) complicated with optic neuritis (ON).Methods:The clinical data of a patient with GBS complicated with ON, who admitted to the Department of Neurology, the First Hospital of Shanxi Medical University in December 2021, were collected, including demographic characteristics, clinical symptoms and signs, laboratory and electrophysiological data, and results of fundus color films. The patients with GBS complicated with ON reported in the literature were also reviewed.Results:A 40-year-old female patient with GBS was diagnosed by the results of electromyography and cerebrospinal fluid tests combining with the history and signs, who was treated with intravenous immunoglobulin on the 3rd day after onset. On the 8th day, her muscle strength improved significantly. However, on the 12th day, the visual field darkened, and on the 19th day, the vision decreased significantly (oculus dexter visual acuity 0.2, oculus sinister visual acuity 0.1 +1) with bilateral papilloedema, a relative afferent pupillary defect and delayed P100 response of the visual evoked potential. Obvious abnormality was not noted in optic nerve magnetic resonance imaging. Thus ON was diagnosed and treated with pulse methylprednisolone therapy. After 8 days of treatment, the visual acuity was completely recovered and there was no abnormality in the ocular fundus. A total of 28 cases of GBS complicated with ON (including the present patient) were reported in the literature. The age of onset was mostly 20-60 years, and there was no gender preference. Mycoplasma pneumoniae was the most common premorbid pathogen and was identified in 7 of the 10 cases in which the causative agent was described. ON usually involved both sides, and 21 of 28 patients had bilateral optic nerves involved. GBS preceded ON or both occurred simultaneously in the majority of patients; GBS preceded ON in 14 of 28 patients, and both occurred simultaneously in 10 of 28 patients. All patients responded well to immunotherapy, and vision was completely recovered in 20 patients. Conclusions:GBS complicated with ON is rare. Attention should be paid to the loss of vision in patients with GBS. Relevant examinations should be completed as soon as possible and immunotherapy should be given.

The awake prone position plays an important role in the treatment of hypoxemia and the improvement of respiratory distress symptoms in non-intubated patients. It is widely used in clinical practice because of its simple operation, safety, and economy. To enable clinical medical staff to scientifically and normatively implement prone position for awake patients without intubation, the committees of consensus formulation, guided by evidence-based methodology and Delphi method, conducted literature search, literature quality evaluation and evidence synthesis around seven topics, including indications and contraindications, evaluation, implementation, monitoring and safety management, termination time, complication prevention and health education of awake prone position. After two rounds of expert letter consultation, Expert consensus on implementation strategy of awake prone positioning for non-intubated patients in China (2023) was formulated, and provide guidance for clinical medical staff.

Hepatocellular carcinoma (HCC) is one of the malignant tumors of the digestive system with the highest morbidity and mortality. The vast majority of patients with intermdiate and advanced HCC have low response rates and poor long-term survival to a series of treatments mainly based on transcatheter arterial chemoembolization (TACE). In recent years, molecular targeted therapy, immunotherapy and their combination with TACE have developed rapidly. This article reviews the research progress of TACE combined with systemic drug therapy in HCC and looks forward to the future direction of precise treatment of HCC.

Composite lymphoma (CL) involving B-cell lymphoma and T-cell lymphoma is extremely rare. Herein, we report three such cases using immunohistochemistry, flow cytometry, and the next-generation sequencing (NGS) to identify the pathological and molecular characteristics of CL. In the first case, the patient was admitted to hospital for generalized pruritic maculopapular rash over the whole body. An excisional biopsy of the skin lesions showed T-cell lymphoma. At the same time, the staging bone marrow (BM) biopsy revealed a diffuse large B-cell lymphoma (DLBCL). After R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) therapies, the patient produced a good response with substantial dissipation of the rashes and relief of skin. The other two patients were admitted to hospital due to lymphadenopathy and were diagnosed with DLBCL and follicular lymphoma (FL) after core needle biopsy of lymph nodes, BM biopsy, BM aspiration, and flow cytometry. Following R-CHOP and R-COP (rituximab, cyclophosphamide, vincristine, and prednisone) therapies, they achieved complete remission unconfirmed (CRu) and complete remission (CR). However, one or two years later, they suffered a relapse of lymphadenopathy. The shocking fact was that re-biopsy of lymphadenopathy revealed peripheral T-cell lymphoma (PTCL) and angioimmunoblastic T-cell lymphoma (AITL). NGS findings identified DNA methyltransferase 3a (DNMT3a), isocitrate dehydrogenase 2 (IDH2), Ras homolog gene family, member A (RHOA), splicing factor 3B subunit 1 (SF3B1), and tumor protein p53 (TP53) mutations. After immunochemotherapy, these patients achieved CRu and CR again. Nevertheless, they suffered a second relapse of T-cell lymphoma. Finally, they died due to progression of disease. We found that the occurrence of CL is associated with Epstein-Barr virus infection and DNMT3a, IDH2, and TP53 mutations, and the prognosis of the disease is closely related to the T-cell lymphoma components.
