OBJECTIVE To explore the clinical efficacy and safety of Huangkui capsule combined with cyclophosphamide and prednisone in the treatment of immunoglobulin A （IgA） nephropathy with renal insufficiency. METHODS A total of 117 patients with IgA nephropathy and renal insufficiency who were hospitalized in the department of nephrology of the Second Affiliated Hospital of Dalian Medical University from February 2021 to March 2024 were divided into prednisone group （n＝38）， cyclophosphamide group （n＝39） and Huangkui group （n＝40） according to the random number table method. On the basis of standardized basic treatment， the three groups were treated with prednisone， prednisone + cyclophosphamide， and prednisone + cyclophosphamide + Huangkui capsule， respectively， with a course of 6 months. The clinical efficacy， renal function indexes， immunoglobulin levels， inflammatory factor levels before and after treatment， and the incidence of adverse reactions during treatment were compared among the three groups. RESULTS Finally， 107 patients completed the study （35 in prednisone group， 37 in cyclophosphamide group， and 35 in Huangkui group）. After 6 months of treatment， there was a statistically significant difference in the total effective rate among the three groups （P＝0.028）， and the total effective rate of the Huangkui group was significantly higher than that of the prednisone group （P＝0.023）. In terms of renal function， the levels of blood urea nitrogen （BUN）， serum creatinine （Scr）， and urinary microalbumin （Umalb） in the three groups after treatment were significantly lower than those before treatment， while the estimated glomerular filtration rate （eGFR） was significantly higher than that before treatment （P＜0.05）. Among them， the Huangkui group was superior to the other two groups in reducing BUN level （P＜0.05）， and both the Huangkui group and cyclophosphamide group were superior to the prednisone group in improving Scr， Umalb and eGFR （P＜0.05）. In terms of immunology， both the Huangkui group and cyclophosphamide group were superior to the prednisone group in increasing IgG level and decreasing IgA and IgM levels （P＜0.05）. In terms of inflammatory factors， E-mail：amychina0411@163.com the Huangkui group was superior to the prednisone group and cyclophosphamide group in reducing tumor necrosis factor-α level （P＜0.05）， and superior to the prednisone group in reducing interleukin-6 level （P＜0.05）. There was no statistically significant difference in the total incidence of adverse reactions among the three groups （P＞0.05）. CONCLUSIONS Huangkui capsule combined with cyclophosphamide and prednisone has a good therapeutic effect on IgA nephropathy with renal insufficiency. It can further improve patients’ renal function and immune function， regulate inflammatory status， and has good safety.

As public hospitals continue to expand,buildings continue to age,sporadic renovation projects are increas-ing,and expenditures are increasing.In order to ensure the safe,stable and efficient operation of the hospital,the piecemeal re-pair project has become an important basic guarantee for the hospital.There are many kinds of sporadic repair projects,and the projects are trivial and scattered.The contradictions among the needs,cost control,management ability and service quality of sporadic repair projects are becoming increasingly prominent,which has become the difficulty and pain point of logistics service management.In the practice of hospital sporadic repair project management,the traditional project management mode is broken,the whole process of fine management system is established,the level of management personnel and the whole process of the pro-ject are effectively integrated,and the management ability and service quality of sporadic maintenance projects are comprehensive-ly improved.

The dynamin superfamily protein (DSP) encompasses a group of large GTPases that are involved in various membrane remodeling processes within the cell. These proteins are characterized by their ability to hydrolyze GTP, which provides the energy necessary for their function in membrane fission, fusion, and tubulation activities. Dynamin superfamily proteins play critical roles in cellular processes such as endocytosis, organelle division, and vesicle trafficking. It is typically classified into classical dynamins and dynamin-related proteins (Drp), which have distinct roles and structural features. Understanding these proteins is crucial for comprehending their functions in cellular processes, particularly in membrane dynamics and organelle maintenance. Classical dynamins are primarily involved in clathrin-mediated endocytosis (CME), a process crucial for the internalization of receptors and other membrane components from the cell surface into the cell. These proteins are best known for their role in pinching off vesicles from the plasma membrane. Structually, classical dynamins are composed of a GTPase domain, a middle domain, a pleckstrin homology (PH) domain that binds phosphoinositides, a GTPase effector domain (GED), and a proline-rich domain (PRD) that interacts with SH3 domain-containing proteins. Functionally, the classical dynamins wrap around the neck of budding vesicles, using GTP hydrolysis to constrict and eventually acting as a “membrane scissor” to cut the vesicle from the membrane. In mammals, there are three major isoforms: dynamin 1 (predominantly expressed in neurons), dynamin 2 (ubiquitously expressed), and dynamin 3 (expressed in testes, lungs, and neurons). Recent studies have also revealed some non-classical functions of classical dynamins, such as regulating the initiation and stabilization of clathrin-coated pits (CCPs) at the early stages of CME, influencing the formation of the actin cytoskeleton and cell division. Drps share structural similarities with classical dynamins but are involved in a variety of different cellular processes, primarily related to the maintenance and remodeling of organelles, and can be mainly categorized into “mediating membrane fission”, “mediating membrane fusion” and “non-membrane-dependent functions”. Proteins like Drp1 are crucial for mitochondrial division, while others like Fis1, Mfn1, and Mfn2 are involved in mitochondrial and peroxisomal fission and fusion processes, which are essential for the maintenance of mitochondrial and peroxisomal integrity and affect energy production and apoptosis. Proteins like the Mx protein family exhibit antiviral properties by interfering with viral replication or assembly, which is critical for the innate immune response to viral infections. Some other proteins are involved in the formation of tubular structures from membranes, which is crucial for the maintenance of organelle morphology, particularly in the endoplasmic reticulum and Golgi apparatus. Studies on dynamin superfamily proteins have been extensive and have significantly advanced our understanding of cellular biology, disease mechanisms, and therapeutic potential. These studies encompass a broad range of disciplines, including molecular biology, biochemistry, cell biology, genetics, and pharmacology. By comprehensively summarizing and organizing the structural features and functions of various members of the dynamin superfamily protein, this review not only deepens the understanding of its molecular mechanisms, but also provides valuable insights for clinical drug research related to human diseases, potentially driving further advancements in the field.

Objective To investigate the environmental contamination related to first patient with carbapenem-re-sistant Acinetobacter baumannii(CRAB)infection and the infection status of relevant patients in a newly established intensive care unit(ICU)of a hospital in Tibetan area,and analyze the transmission risk.Methods From the ad-mission in ICU of a patients who was first detected CRAB on November 15,2021 to the 60th day of hospitalization,all patients who stayed in ICU for＞48 hours were performed active screening on CRAB.On the 30th day and 60th day of the admission to the ICU of the first CRAB-infected patient,environment specimens were taken respectively 2 hours after high-frequency diagnostic and therapeutic activities but before disinfection,and after disinfection but before medical activities.CRAB was cultured with chromogenic culture medium.Results Among the 13 patients who were actively screened,1 case was CRAB positive,he was transferred from the ICU of a tertiary hospital to the ICU of this hospital on November 19th.On the 40th day of admission to the ICU,he had fever,increased frequency for sputum suction,and CRAB was detected.The drug sensitivity spectrum was similar to that of the first case,and he also stayed in the adjacent bed of the first case.64 environmental specimens were taken,and 9 were positive for CRAB,with a positive rate of 14.06％,8 sampling points such as the washbasin,door handle and bed rail were positive for CRAB after high-frequency diagnostic and therapeutic activities.After routine disinfection,CRAB was detected from the sink of the washbasin.Conclusion For the prevention and control of CRAB in the basic-level ICU in ethnic areas,it is feasible to conduct risk assessment on admitted patients and adopt bundled prevention and con-trol measures for high-risk patients upon admission.Attention should be paid to the contaminated areas(such as washbasin,door handle,and bed rail)as well as the effectiveness of disinfection of sink of washbasin.

As a serious cardiovascular disease, atherosclerosis (AS) causes chronic inflammation and oxidative stress in the body and poses a threat to human health. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a member of the phospholipase A2 (PLA2) family, and its elevated levels have been shown to contribute to AS. Lp-PLA2 is closely related to a variety of lipoproteins, and its role in promoting inflammatory responses and oxidative stress in AS is mainly achieved by hydrolyzing oxidized phosphatidylcholine (oxPC) to produce lysophosphatidylcholine (lysoPC). Moreover, macrophage apoptosis within plaque is promoted by localized Lp-PLA2 which also promotes plaque instability. This paper reviews those researches of Chinese medicine in treating AS via reducing Lp-PLA2 levels to guide future experimental studies and clinical applications related to AS.

Objective To investigate the associations of reproductive health indicators with lung function and chronic obstructive pulmonary disease(COPD)among women aged 40 years and above.Methods From Jul to Sep,2021,female subjects aged 40 years and above were randomly selected from the Shanghai Suburban Adult Cohort and Biobank for COPD screening.A questionnaire was used to obtain information on demographic characteristics and reproductive health indicators.Linear regression was used to analyze the effects of reproductive health indicators on forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1).Logistic regression was also used to analyze the effects of reproductive health factors on FVC as a percentage of the predicted value(FVC%Pred)and FEV1%Pred as well as on COPD.Results A total of 1876 women aged 40 years and above were enrolled with mean age of(62.1±8.2)years old,among them,78.1%were menopausal,and 40.9%had been pregnant≥3 times.Multivariate analysis showed that FVC and FEV1 decreased in postmenopausal women,but menopause was not associated with a decrease in their percentage of predicted values.Pregnancies≥3 times was a risk factor for COPD(for 3 times,OR=4.92,95%CI:1.48-19.95,P<0.05;for≥4 times,OR=9.06,95%CI:2.32-41.57,P<0.01),while pregnancies of 2 times did not increase the risk of COPD.Conclusion In women aged 40 years and above,menopause is associated with poorer FVC and FEV1,and excessive pregnancy(≥3 times)is a risk factor for COPD.

Objective To analyze the serum PD-L1 levels of gastric cancer patients and its relationship with tumor stage and prognosis.Methods Serum of sixty patients with pathological diagnosis of gastric cancer in our hospital from August 2018 to December 2019 were collected,and the serum of 15 healthy adults as a control.The serum PD-L1 levels was measured by enzyme linked immunosorbent assay(ELISA).The serum PD-L1 levels between gastric cancer patients and healthy adults were compared.The relationship between the serum PD-L1 levels and prognosis of gastric cancer patients with different stages was analyzed.Finally,the PD-L1 expression in tumor tissues was detected by immunohistochemical staining,and its correlation with serum PD-L1 levels was analyzed.Results The serum PD-L1 levels of gastric cancer group was significantly higher than that of the control group.The serum PD-L1 levels in patients with stage Ⅲ and Ⅳ gastric cancer was significantly higher than that in stage Ⅰ and Ⅱ.The serum PD-L1 levels in gastric cancer patients with peritoneal metastasis was significantly elevated,indicating poor prognosis.Kaplan-Meier survival analysis showed that the survival time of gastric cancer patients with higher level of serum PD-L1 was shorter than those with lower ones.We further evaluated the PD-L1 expression in tumor tissues.There was no significant correlation between the serum PD-L1 levels and that in tumor tissues.Conclusions The serum PD-L1 levels of gastric cancer patients was higher than that of healthy adults,and which gradually increased with the progression of the disease.Gastric cancer patients with peritoneal metastasis had a much higher serum PD-L1 levels,and there was no significant correlation between serum PD-L1 levels and PD-L1 expression in tumor tissues.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Objective To investigate the effect of varying blood pressure stratification on renal function in the diabetic population.Methods A prospective cohort study was conducted,enrolling 9 489 diabetic patients from a total of 101 510 Kailuan Group employees who underwent health examinations between July 2006 and October 2007.The follow-up period was(8.6±4.0)years.Participants were categorized into four groups based on their baseline blood pressure levels:normal blood pressure(systolic blood pressure<120 mmHg and diastolic blood pressure<80 mmHg),elevated blood pressure(systolic blood pressure 120-130 mmHg and diastolic blood pressure<80 mmHg),stage 1 hypertension(systolic blood pressure 130-140 mmHg and/or diastolic blood pressure 80-90 mmHg),and stage 2 hypertension(systolic blood pressure≥140 mmHg and/or diastolic blood pressure≥90 mmHg).The incidence density of chronic kidney disease(CKD)was compared among these groups.A multivariate Cox proportional hazards regression model was employed to assess the effects of different blood pressure levels on renal function in diabetic patients,with the stability of the results confirmed using a multivariate time-dependent Cox proportional hazards model.Sensitivity analysis was conducted after excluding cases of cardiovascular disease(CVD)during follow-up,and cases using antihypertensive and antidiabetic medications at baseline.Results(1)At baseline,stage 1 hypertension patients demonstrated statistically significant higher differences with age and body mass index(BMI)compared to normal blood pressure group(P<0.05).(2)By the end of the follow-up,2 294 cases of CKD were identified,including 1 117 cases of estimated glomerular filtration rate(eGFR)decline and 1 575 cases of urinary protein.The incidences density of CKD,eGFR decline and urinary protein for stage 1 hypertension group were 39.4,16.3 and 25.5 per thousand person-years,respectively,all of which were statistically significant different from normal blood pressure group(log-rank test,P<0.01).(3)Multivariate Cox regression analysis revealed that,compared to the normal blood pressure group,stage 1 hypertension was associated with a 29%increased risk of CKD(HR=1.29,95%CI 1.09-1.52)and a 40%increased risk of eGFR decline(HR=1.40,95%CI 1.08-1.80)in diabetic individuals.Conclusion Stage 1 hypertension significantly increases the risk of CKD and eGFR decline in diabetic individuals,with a particularly notable effect on the risk of eGFR decline.

Odontogenic maxillary sinusitis(OMS)is a subtype of maxillary sinusitis(MS).It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion.Due to the lack of unique clinical features,OMS is difficult to distinguish from other types of rhinosinusitis.Besides,the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis.Its current diagnosis and treatment are thus facing great difficulties.The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS.However,this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality.Based on systematically reviewed literature and practical experiences of expert members,our consensus focuses on characteristics,symptoms,classification and diagnosis of OMS,and further put forward multi-disciplinary treatment decisions for OMS,as well as the common treatment complications and relative managements.This consensus aims to increase attention to OMS,and optimize the clinical diagnosis and decision-making of OMS,which finally provides evidence-based options for OMS clinical management.
