Objective: To explore the safety and feasibility of the disconnection of the left renal artery preferentially during robot-assisted inferior vena cava (IVC) thrombectomy for patients with left renal cell carcinoma and tumor emboli. Methods: Clinical data of 7 patients who underwent robot-assisted IVC thrombectomy and radical nephrectomy in the First Affiliated Hospital of Zhengzhou University during Dec.2021 and Oct.2024 were retrospectively analyzed.Thrombectomy was performed first,followed by nephrectomy. The “IVC-first, kidney-last”robotic technique was developed to minimize chances of IVC thrombus. When patients in left lateral decubitus position, the left renal artery was severed from the right side through the inferior vena cava and abdominal aorta. After removal of thrombus from IVC was completed, patients changed to the right lateral position to complete radical left nephrectomy. Results: Imaging examinations revealed that the median diameter of the renal cell carcinomas was 83(46-99) mm; the median length of the inferior vena cava cancerous emboli was 49(2-91) mm.According to the Mayo classification,the cancerous emboli were gradeⅠ in 2 cases,gradeⅡ in 4 cases,and grade Ⅲ in 1 case.All surgeries were successful.The median operation time was 248(201-331) minutes,blood loss 500(200-1000) mL,and 6 cases required intraoperative blood transfusion.The median time for transition into the intensive care unit was 1(1-4) days,and drainage tube removal 6(5-12) days.Serum creatinine increased significantly in 5 cases,4 of which returned to normal after 1 week,but 1 had renal insufficiency (creatinine 166 μmol/L).Chylous fistula occurred in 1 patient,and lower extremity venous thrombosis developed in 3 patients.Pathological examinations indicated 6 cases of renal cell carcinoma and 1 case of MiT family translocation renal cell carcinoma.During the median follow-up of 17(1-35) months,5 cases were tumor-free,while 2 had lung and retroperitoneal metastases.They received targeted therapy of axitinib combined immunotheraphy and lived with tumors. Conclusion: In the left lateral position for left renal cell carcinoma with cancerous emboli,robot-assisted laparoscopic thrombectomy by crossing the inferior vena cava and abdominal aorta and disconnecting the left renal artery first is safe and feasible.

OBJECTIVE To explore the practice pathway and evaluate the effectiveness of the resident pharmacists stationed in the Drug Clinical Trial Institution Office (hereinafter referred to as the “GCP resident pharmacist”) in the management of dermatological drug clinical trials. METHODS The practical approach of GCP resident pharmacists participating in dermatological drug clinical trials at our hospital was introduced. A retrospective analysis was conducted on the data of dermatological drug clinical trials from 2021 to 2024, comparing efficiency and quality indicators between dermatological clinical trials and those of other specialties. RESULTS With the involvement of our hospital’s GCP resident pharmacists throughout, the process for dermatology drug clinical trials was constructed and optimized, a dedicated quality control system was established, and the acceleration strategy for subject enrollment was optimized. The number of dermatological drug clinical trials at our hospital showed a compound annual growth rate of 69.56% from 2021 to 2023. In terms of efficiency indicators, the approval waiting time for dermatological drug clinical trials was (12.31±4.99) days, which was significantly shorter than that of other specialties ([ 19.68±6.09) days, P<0.05]. Regarding quality indicators, the enrollment rate for dermatological drug clinical trials was 75.71%(50.00%,114.48%), which was significantly higher than that of other specialties [51.00%(25.00%,174.17%), P<0.05]. The numbers of first quality control issues ([ 8.31±3.25)items vs.( 11.68±4.49)items] and protocol deviations [5.5(2.0,11.0)times vs. 11.0(5.5,17.5)times] were significantly lower than those of other specialties (P<0.05). CONCLUSIONS GCP resident pharmacists significantly enhance the overall efficiency of dermatological drug clinical trials, playing a crucial role in ensuring the reliability and authenticity of drug clinical trials, as well as safeguarding the rights and safety of trial subjects.

Secondary organizing pneumonia after infection is a pathological condition characterized by connective tissue filling and obstructing the alveoli and bronchioles, in which following an infection in the lung, the inflammatory response is not controlled in a timely and effective manner. The pathogenesis and treatment of this condition can be interpreted through the Sanjiao membranous tube theory and the concept of stagnation within the pulmonary micro-membrane. Sanjiao is conceptualized as a four-way membranous tube that internally connects with the zangfu organs and externally with the skin and muscles, enabling the circulation of energy and fluids throughout the body. It also maintains communication with the zangfu micro-membranes. Within the lungs, the pulmonary micro-membrane is distributed and connected to the upper jiao membranous tube, facilitating the movement of qi and fluids and supporting nutrient distribution. External pathogens may invade the Sanjiao membranous system through the external membranous tube, travel internally along this system, and transform into latent pathogens that settle within the pulmonary micro-membrane. These latent pathogens can subsequently transform into heat or dampness, leading to the depletion of lung qi and impairing the lung′s ability to regulate and transport body fluids. Consequently, fluids may seep into the pulmonary micro-membrane, where they are transformed into dampness, turbidity, and phlegm. The accumulation of damp-turbidity and phlegm obstructs the flow of qi and blood, resulting in blood stasis in the pulmonary collaterals. This stagnation occurring within both the pulmonary micro-membrane and its associated collaterals underlies the development of secondary organizing pneumonia after infection. In severe cases, this condition may progress to pulmonary interstitial fibrosis. The therapeutic approach emphasizes expelling latent pathogens, regulating and dredging the pulmonary micro-membrane, tonifying the healthy qi, and supporting health. Regulating and dredging the pulmonary micro-membrane is a crucial step, with a focus on promoting the flow of lung qi, resolving dampness and phlegm, and activating blood circulation to remove stasis.

Hemoglobin A1c (HbA1c) has a unique structure that makes monoclonal antibody (mAb) preparation challenging. This study aims to develop a method for preparing HbA1c mAbs and establish a fluorescent immunochromatographic assay (FICA) for rapid detection of HbA1c. Three glycosylated peptides were synthesized and used to prepare complete antigens, which were identified by dot enzyme-linked immunosorbent assay (Dot-ELISA) and ultraviolet absorption spectroscopy. The complete antigens and natural HbA1c were used for cross-immunization of mice, and the optimal complete antigen was selected. The mouse with the highest serum titer was chosen for mAb preparation. The purity and specificity of the mAbs were verified, and a FICA method was developed. The optimal complete antigen, with a titer of 1:512 000, was successfully prepared and selected. Fusion with splenocytes resulted in four specific HbA1c antibodies (purity > 90%). The best antibody exhibited a binding constant (Ka) of 1.67×1010 L/mol with the antigen. Based on this antibody, a FICA method was successfully established, capable of producing results within 15 min. The method demonstrated a good linear range (3%-13% HbA1c, y=0.071 3x+0.005 6, R2=0.993 7), recovery rates of 98%-102%, precision < 10.00%, and no nonspecific reactions. Clinical testing of 210 samples showed positive agreement of 96.36%, negative agreement of 97.00%, and overall agreement of 96.68%. The receiver operating characteristic (ROC) curve analysis yielded an area under curve (AUC) of 0.980 9 [95% confidence interval (CI): 0.961 0-1.000 0], with high consistency verified in multicenter studies. We successfully developed a key technique for preparing HbA1c monoclonal antibodies and established a FICA method for rapid detection of HbA1c. It will provide an efficient and convenient detection method for the early diagnosis and long-term management of diabetes and its complications.

ObjectiveTo understand the awareness of knowledge about chronic obstructive pulmonary disease (COPD) and influencing factors among residents in Yangpu District, Shanghai. MethodsWe used cluster random sampling method to conduct face-to-face questionnaire surveys on selected household residents in 12 streets of Yangpu District. The survey questions included their understanding of COPD name, lung function test, and COPD related knowledge. Multivariate logistic regression analysis was used to analyze the influencing factors of awareness rate. ResultsA total of 1 440 people were ultimately included in the analysis, and the awareness rates of COPD name, lung function test, and COPD awareness were 19.93%, 18.61%, and 14.95%, respectively. Among the people who knew the name of COPD, awareness rate of shortness of breath or dyspnea was the highest (84.12%) in the three main symptoms of COPD. Among the main risk factors of COPD, second-hand smoke(86.78%)and smoking (85.82%) were the highest. The main ways to obtain knowledge of COPD names were through television (12.60%) and the internet (11.97%). The results of multivariate logistic regression analysis showed that men were significantly higher than women in the awareness of COPD name, lung function test, and COPD knowledge, with the OR values of (OR=1.39, 95%CI:1.08‒1.79), (OR=1.47,95%CI:1.12‒1.92) and (OR=1.37,95%CI:1.02‒1.84), respectively. The awareness rate of COPD names and lung function tests was the highest among people aged ≥ 65 years old, while the awareness rate of COPD knowledge was the highest among people aged 35‒50 years old. The awareness rate of COPD names was the highest among people with college education or above, civil servants, teachers, and medical staff, people with an annual household income of 100 000‒200 000 yuan. ConclusionThe overall awareness rate of COPD names, lung function tests, and COPD related knowledge among residents in Yangpu District is still at a low level. We should intensify the promotion and education of COPD among key groups such as women, young people, and those with low income, in order to improve the overall awareness rate of COPD among the population.

This article presents a case report of right vocal cord paralysis resulting from herpes simplex virus infection in an older adult. The patient initially presented with fever, blisters on the lips and right cheek, followed by the gradual onset of hoarseness and difficulty in swallowing. Laryngoscopy revealed fixation of the right vocal cord while the left vocal cord exhibited normal movement. A high level of herpes simplex virus type 1 IgM antibody was detected during the disease progression. Treatment involving mid-dose glucocorticoid and methylcobalamin neurotrophic therapy, swallowing and vocal rehabilitation training, as well as enteral nutrition support, led to alleviation of hoarseness and improved ability to drink water in small sips. Follow-up laryngoscopy indicated partial restoration of movement in the right vocal cord. The article not only outlines the diagnosis and treatment of this case but also reviews relevant literature to broaden clinicians' knowledge of viral-induced vocal cord paralysis in the elderly. It also emphasizes the importance of a geriatric interdisciplinary team in managing complex diseases in older patients.

Renal interstitial fibrosis(RIF) is the main pathological manifestation of chronic kidney disease. Due to the complexity of the mechanism, there is no specific treatment for RIF in clinical practice. The abnormal activation of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B(Akt) signaling pathway and the activation of downstream target genes are key drivers of RIF induction and progression. Traditional Chinese medicine has the characteristics of precise efficacy and minimal toxic side effects, and the occurrence and development of RIF can be regulated by multiple targets and mutual coordination. This review focuses on the PI3K/Akt signaling pathway and summarizes the potential targets and regulatory mechanisms of traditional Chinese medicine in the treatment of RIF. It is found that various effective ingredients (such as sinomenine, mangiferin, coumarin derivates from Hydrangea paniculata, etc.) and formulas (such as Fushengong decoction, Qi-Bang-Yi-Shen formula, etc.) of traditional Chinese medicine can inhibit fibroblast proliferation, improve inflammation and oxidative stress, maintain mitochondrial stability, and slow down ferroptosis through this pathway, thereby delaying the occurrence and progression of RIF.
