OBJECTIVE To evaluate the efficacy and safety of high-dose ilaprazole combined with amoxicillin for newly diagnosed elderly patients with Helicobacter pylori （Hp） infection， and analyze independent risk factors for failure of Hp infection eradication treatment. METHODS Totally 200 cases of newly diagnosed elderly patients with Hp infection in Xinxiang Central Hospital from August 1， 2021 to December 1， 2024 were selected and randomly divided into control group and study group， with 100 cases in each group. The control group was treated with classic quadruple therapy regimen （Amoxicillin capsules+ Clarithromycin tablets+Bismuth potassium citrate tablets+Ilaprazole enteric-coated tablets）. The study group was treated with high- dose Ilaprazole enteric-coated tablets+Amoxicillin capsules. All patients were administered medication for 2 weeks. Hp eradication rates in the two groups were compared using intention-to-treat （ITT） and per-protocol （PP） analyses. The incidence of adverse reactions in both groups was also recorded. The multiple-factor Logistic regression analysis was used to identify independent risk factors for failure of Hp infection eradication treatment. RESULTS In ITT and PP analyses， there was no significant difference of Hp eradication rates between the two groups （P＞0.05）. There was no significant difference in incidence of mild to moderate adverse reactions between the two groups （P＞0.05）. BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease were identified as independent risk factors influencing the failure of Hp infection eradication treatment （P＜0.05）. CONCLUSIONS The efficacy and safety of high-dose ilaprazole combined with amoxicillin are comparable to classic quadruple therapy regimen in treating newly diagnosed elderly patients with Hp infection. Independent risk factors influencing the failure of Hp infection eradication treatment include BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease.

The connection between tendons and bones is called the tendon bone connection. With the continuous improvement of national sports awareness, excessive exercises and the related intensity are prone to damage the tendon bone connection. Tendon bone healing is a complex repair and healing process involving multiple factors, and good tendon bone healing is a prerequisite for its physiological function. The complexity of tendon bone structure also poses great challenges to the repair of tendon bone injuries. In recent years, researches have found that stem cells, growth factors, macrophages, and other factors are closely related to the healing process of tendon bone injuries, among which macrophages play an important role in the healing process. The authors reviewed relevant research literature in recent years and summarized the role of macrophages in tendon bone healing, in order to provide new ideas and directions for treatment strategies to promote tendon bone healing.

Acute lung injury (ALI) has been a kind of acute and severe disease that is mainly characterized by systemic uncontrolled inflammatory response to the production of huge amounts of reactive oxygen species (ROS) in the lung tissue. Given the critical role of ROS in ALI, a Fe₃O₄ loaded bovine serum albumin (BSA) nanocluster (BF) was developed to act as a nanomedicine for the treatment of ALI. Combining with NIR irradiation, it exhibited excellent ROS scavenging capacity. Significantly, it also displayed the excellent antioxidant and anti-inflammatory functions for lipopolysaccharides (LPS) induced macrophages (RAW264.7), and Sprague Dawley rats via lowering intracellular ROS levels, reducing inflammatory factors expression levels, inducing macrophage M2 polarization, inhibiting NF-κB signaling pathway, increasing CD4⁺/CD8⁺ T cell ratios, as well as upregulating HSP70 and CD31 expression levels to reprogram redox homeostasis, reduce systemic inflammation, activate immunoregulation, and accelerate lung tissue repair, finally achieving the synergistic enhancement of ALI immunotherapy. It finally provides an effective therapeutic strategy of BF + NIR for the management of inflammation related diseases.

Working memory is an executive memory process that includes encoding, maintenance, and retrieval. These processes can be modulated by transcranial alternating current stimulation (tACS) with sinusoidal waves. However, little is known about the impact of the rate of current change on working memory. In this study, we aimed to investigate the effects of two types of tACS with different rates of current change on working memory performance and brain activity. We applied a randomized, single-blind design and divided 81 young participants who received triangular wave tACS, sinusoidal wave tACS, or sham stimulation into three groups. Participants performed n-back tasks, and electroencephalograms were recorded before, during, and after active or sham stimulation. Compared to the baseline, working memory performance (accuracy and response time) improved after stimulation under all stimulation conditions. According to drift-diffusion model analysis, triangular wave tACS significantly increased the efficiency of non-target information processing. In addition, compared with sham conditions, triangular wave tACS reduced alpha power oscillations in the occipital lobe throughout the encoding period, while sinusoidal wave tACS increased theta power in the central frontal region only during the later encoding period. The brain network connectivity results showed that triangular wave tACS improved the clustering coefficient, local efficiency, and node degree intensity in the early encoding stage, and these parameters were positively correlated with the non-target drift rate and decision starting point. Our findings on how tACS modulates working memory indicate that triangular wave tACS significantly enhances brain network connectivity during the early encoding stage, demonstrating an improvement in the efficiency of working memory processing. In contrast, sinusoidal wave tACS increased the theta power during the later encoding stage, suggesting its potential critical role in late-stage information processing. These findings provide valuable insights into the potential mechanisms by which tACS modulates working memory.

Objective To explore the influence of gender on the prognosis of patients with atrial fibrillation(AF)undergoing left atrial appendage occlusion(LAAO).Methods All non-valvular AF patients who were admitted in our hospital and underwent LAAO from August 2014 to August 2021 were enrolled and grouped according to gender.Their general information,including gender,age,comorbid underlying diseases,and results of transthoracic echocardiography and transesophageal echocardiography(TEE)were collected.The incidences of device-related thrombosis(DRT),pericardial tamponade,stroke,bleeding,hospitalization for heart failure,and cardiac death were recorded during follow-up.The influence of gender on the prognosis of these patients was analyzed.Results There were totally 673 patients with non-valvular AF were enrolled,including 366 males and 307 females,at a mean age of 68.2±9.4 years.When compared with the male patients,the female ones had a higher CHA2DS2-VASc score(P＜0.01),but smaller proportions of history of stroke,average compression ratio of occluders,and incidence of residual shunt(＜3 mm)after occlusion(P＜0.05).In 45～60 d after surgery,TEE revealed that there were 17 cases of DRT,including 8 males(2.2％)and 9 females(2.9％),though without statistical difference between the groups.Among the 17 DRT cases,1 experienced stroke,and the incidence of stroke was 5.9％in those with DRT and 0.5％without.There were 4 cases of postoperative pericardial tamponade,including 1 in the male group and 3 in the female group(no significant difference),and all of them were improved after pericardial puncture and fluid extraction.During the follow-up period of 40.2±20.5 months,no obvious differences were observed between the 2 groups in terms of stroke,bleeding,hospitalization for heart failure,and cardiogenic death.Conclusion Gender shows no significant effect on the prognosis of patients with non-valvular AF after LAAO.

Objective:To investigate the effect of 980 nm semiconductor laser preablation of urethra mucosa at the prostatic tip in small volume benign prostatic hyperplasia (BPH).Methods:The case data of 120 patients diagnosed with small volume BPH in the Yan′an University Affiliated Hospital from June 2020 to June 2022 were retrospectively analyzed, and they were divided into improved group and conventional group according to different treatment methods, with 60 cases in each group. Patients in the improved group were treated with 980 nm semiconductor laser preablation of urethra mucosa at the prostatic tip, and patients in the conventional group were treated with 980 nm semiconductor laser vaporization of prostate. The sexual function of the patients was evaluated by the international erectile function index-5(IIEF-5) score, erectile hardness score (EHS) and retrograde ejaculation before surgery and 1, 3, 6, and 12 months after surgery. International prostate symptom scale (IPSS), quality of life (QOL) score, the maximum urine flow rate (Qmax) and postvoid residual urine (PVR) were used to evaluate urinary control function. The incidence of urinary incontinence, bladder neck contracture and other complications were compared between the two groups. Measurement data were expressed as mean±standard deviation ( ± s), and t-test was used for comparison between groups. The count data were expressed as cases and percentage, and Chi-square test was used for comparison between groups. Results:There was no significant difference in PVR, Qmax, IPSS score, QOL score, IIEF-5 score and EHS score between two groups ( P>0.05). In terms of PVR, Qmax, IPSS score, QOL score, IIEF-5 score and EHS score at 1, 3, 6 and 12 months after surgery, all these parameters were significantly improved compared with the preoperative, the differences were statistically significant ( P< 0.05). However, there was no significant difference between the two groups ( P> 0.05). There was no significant difference in IIEF-5 score and EHS score between the two groups during postoperative follow-up and before and after operation ( P> 0.05). The incidence of retrograde ejaculation rate in the improved group was lower than that in the conventional group during the follow-up 1, 3, 6 months after surgery, and the difference was statistically significant ( P<0.05). In the follow-up 1, 3 months after surgery, the incidence of stress urinary incontinence in the improved group was lower than that in the conventional group, the differences were statistically significant ( P< 0.05). At follow-up 6, 12 months after surgery, the rates of stress urinary incontinence were similar between the two groups, and the difference was not statistically significant ( P> 0.05). In the follow-up 12 months after surgery, there were 2 cases (3.33%) of bladder and neck contracture in the improved group, and 8 cases (13.33%) in the conventional group, the difference was statistically significant ( P<0.05). Conclusions:The effect of 980 nm semiconductor laser preablation of urethra mucosa at the prostatic tip in small volume BPH patients is similar to that of conventional vaporization, and the operation time is short. At the same time, the proximal 1 cm tissue of the verticulae and the integrity of the bladder neck are preserved, and the internal and external sphincter of the urethra are protected, thus improving the immediate postoperative urinary control rate and the incidence of retrograde ejaculation in small volume BPH patients.

Objective:To evaluate the clinical value of a capillary electrophoresis-based method for gene diagnosis of hyperphenylalaninemia.Methods:In this single-center prospective study, 40 newborns with suspected hyperphenylalaninemia detected by neonatal liquid chromatography-tandem mass spectrometry screening at Nanjing Maternity and Child Health Care Hospital from February 2021 to February 2023 were included, with 22 males, 18 females and a mean age at diagnosis of 21.93 days.Capillary electrophoresis was used to detect 85 variants of the phenylalanine hydroxylase ( PAH) gene in 40 newborns with suspected hyperphenylalaninemia.The PAH gene of undiagnosed patients was further analyzed by Sanger sequencing.The detection rate, sensitivity and specificity of capillary electrophoresis were calculated. Results:Among these 40 newborns with suspected hyperphenylalaninemia, 71 PAH variants were detected by capillary electrophoresis, 32 patients were clearly diagnosed, only 1 pathogenic variant was found in 5 patients, and no pathogenic variant was found in the last 3 patients.Therefore, the detection rate, sensitivity and specificity of capillary electrophoresis for analysis of the PAH gene were 80.00%, 88.75% and 100%, respectively. Conclusions:The capillary electrophoresis-based method can rapidly, efficiently and accurately detect PAH gene variants at lower cost and is a promising gene detection method for hyperphenylalaninemia in clinical practice.

As the search for effective treatments for COVID-19 continues, the high mortality rate among critically ill patients in Intensive Care Units (ICU) presents a profound challenge. This study explores the potential benefits of traditional Chinese medicine (TCM) as a supplementary treatment for severe COVID-19. A total of 110 critically ill COVID-19 patients at the Intensive Care Unit (ICU) of Vulcan Hill Hospital between Feb., 2020, and April, 2020 (Wuhan, China) participated in this observational study. All patients received standard supportive care protocols, with a subset of 81 also receiving TCM as an adjunct treatment. Clinical characteristics during the treatment period and the clinical outcome of each patient were closely monitored and analysed. Our findings indicated that the TCM group exhibited a significantly lower mortality rate compared with the non-TCM group (16 of 81 vs 24 of 29; 0.3 vs 2.3 person/month). In the adjusted Cox proportional hazards models, TCM treatment was associated with improved survival odds (P < 0.001). Furthermore, the analysis also revealed that TCM treatment could partially mitigate inflammatory responses, as evidenced by the reduced levels of proinflammatory cytokines, and contribute to the recovery of multiple organic functions, thereby potentially increasing the survival rate of critically ill COVID-19 patients.
