OBJECTIVE To evaluate the efficacy and safety of amoxicillin combined with proton pump inhibitor （PPI） or potassium-competitive acid blocker （P-CAB） for Helicobacter pylori （Hp） eradication. METHODS Randomized controlled trial （RCTs） on amoxicillin combined with PPI or P-CAB for Hp eradication were retrieved from PubMed， Embase， the Cochrane Library， Web of Science， CNKI， Wanfang， and VIP data. The search time frame was from database inception to September 5， 2025. After literature screening， data extraction， and quality assessment， a network meta-analysis was performed using Stata 17.0 software. RESULTS A total of 12 RCTs involving 5 515 patients were included， encompassing 8 therapeutic regimens： PPI combined with high-dose amoxicillin for 14 days （TR1）， PPI combined with low-dose amoxicillin for 14 days （TR2）， P-CAB combined with high-dose amoxicillin for 7 days （TR3）， P-CAB combined with high-dose amoxicillin for 14 days （TR4）， P-CAB combined with high-dose amoxicillin for 10 days （TR5）， P-CAB combined with low-dose amoxicillin for 7 days （TR6）， P-CAB combined with low-dose amoxicillin for 14 days （TR7）， and P-CAB combined with low-dose amoxicillin for 10 days （TR8）. The network meta-analysis results showed that， in terms of intention-to-treat Hp eradication rates， the eradication rates of TR5 and TR4 were significantly higher than those of TR3， TR8， TR6 and TR1 （ P ＜0.05）. The surface under the cumulative ranking curve （SUCRA） values from highest to lowest were： TR4 （89.7%）＞TR5 （82.3%）＞TR7 （71.5%）＞ TR2 （48.6%）＞TR1 （43.9%）＞TR8 （28.7%）＞TR3 （22.7%）＞TR6 （12.6%）. Regarding safety， the incidence of adverse reactions in TR3 and TR5 was significantly lower than that in TR1 （ P ＜0.05）. The SUCRA values from highest to lowest were： TR1 （91.3%）＞TR4 （79.8%）＞TR5 （55.0%）＞TR7 （50.9%）＞TR8 （41.3%）＞TR2 （36.4%）＞TR3 （27.6%） ＞TR6 （17.7%）. CONCLUSIONS Although the regimen of P-CAB combined with high-dose amoxicillin for 14 days demonstrates the best efficacy， the combination of P-CAB with high-dose amoxicillin for 10 days exhibits a better balanced profile in terms of both efficacy and safety.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To investigate the risk factors and independent risk factors associated with papillary thyroid carcinoma(PTC)cervical lymph node metastasis,and to assess the predictive efficacy of independent risk factors on metastatic lymph nodes.Methods Clinical and ultrasonographic data of 279 patients with PTC were collected,and the patients were divided into two groups according to the presence of cervical lymph node metastasis based on postoperative pathology,and the relevant characteristics of the two groups were ana-lyzed to explore the risk factors and independent risk factors associated with cervical lymph node metastasis in PTC,and the predictive ef-ficacy of independent risk factors on cervical metastatic lymph nodes was compared by receiver operating characteristic(ROC)curves.Results Age,gender and the maximum diameter,border,shape,microcalcifications,and distance from the thyroid capsule of cancer nodes were risk factors for cervical lymph node metastasis in both groups(P＜0.05);male,maximum diameter of cancer nodes 10mm,microcalcifications,and distance from the thyroid capsule ≤2mm were independent risk factors for cervical lymph node metastasis in PTC(P＜0.05);the AUC of the combination of four independent risk factors was 0.785(95％CI:0.721-0.849,P＜0.05),with the highest efficacy in predicting cervical lymph node metastasis.Conclusion Male,maximum diameter of cancer nodes ≥10mm,mi-crocalcifications,and distance from the thyroid capsule ≤2mm were independent risk factors for cervical lymph node metastasis of PTC,and the combination of four independent risk factors could assist in assessing the risk of cervical lymph node metastasis of PTC and improve patient prognosis.

Objective:To analyze the thickness of peripapillary retinal nerve fiber layer (pRNFL) and photoreceptor (PR) sublayer in Leber hereditary optic neuropathy (LHON) and G11778A mutation carriers. Methods:A cross sectional study. From September 2020 to October 2021, 68 LHON patients (136 eyes) (patient group) and 40 G11778A mutation carriers (80 eyes) of LHON patients' families (carrier group) were included in the study. All patients were found to have G11778A mutation by Genetic testing. Forty healthy volunteers with 80 eyes matched to the age and gender of the patient group were recruited as a normal control group. All eyes were examined by optical coherence tomography (OCT). The pRNFL thickness was automatically measured by the built-in software of the OCT device. The total retinal thickness (MT) and the thickness of the outer bundle layer (OPL), outer nuclear layer (ONL), external limiting membrane to retinal pigment epithelium (ELM-RPE) in macular OCT images were measured by Image J software. Linear mixed model was used to analyze and compare the thickness of pRNFL, macular fovea and four layers above the nasal and temporal paracentral retina in patients, carriers and normal controls. The correlation between pRNFL and macular retinal sublayer thickness and the course of disease was also analyzed. Results:The thickness of the upper and lower pRNFL, temporal pRNFL and average pRNFL of the patients were smaller than those of the carriers and the normal control group ( P<0.01), and the nasal pRNFL thickness of the patients was smaller than that of the carriers ( P<0.01). Fovea: compared with the normal control group, the thickness of MT and ONT in the patient group was decreased, ONL thickness decreased in carrier group, with the significant different ( P<0.05). Parafovea: compared with normal control group, the thickness of MT and temporal ONL decreased and temporal OPL increased in the patients group, with the significant different ( P<0.05). In the carrier group, the thickness of MT and temporal, nasal ONL decreased, and the thickness of nasal OPL increased, with the significant different ( P<0.05). Compared with the carrier group, the MT thickness of the patient group was decreased, and the nasal ONL and nasal ELM-RPE thickness were increased, with the significant different ( P<0.05). Correlation analysis results showed that the thinning of pRNFL in the superior, nasal, temporal and average ( r=-0.22, -0.21, -0.25, -0.22), and the thickening of ELM-RPE in foveo-temporal ( r=0.19) were correlated with the course of disease ( P<0.05). Conclusions:The pRNFL of LHON patients with G11778A mutation becomes thinner and is related to the course of the disease. There were significant differences in the thickness of MT and PR sublayers between patients and carriers compared to the normal control group.

Objective:To observe the characteristics of pattern electroretinogram (PERG) and the photopic negative response (PhNR) of flash electroretinogram (FERG) in patients and carriers with Leber hereditary optic neuropathy (LHON).Methods:A cross sectional, observational study. Thirty-two patients (64 eyes) diagnosed with LHON (LHON group) and 15 normal members with the same mutation in patient's family (carrier group) were included in this study from February 2021 to November 2021 in the Department of Ophthalmology of Renmin Hospital of Wuhan University. All patients in LHON group were males (100.0%, 32/32) and the average age was 23.34±7.41 years. In the carrier group of 15 cases (30 eyes), there were 2 males (13.3%, 2/15) and 13 females (86.7%, 12/15). The average age was 43.44±7.65 years. Twenty-four healthy subjects (48 eyes) in the same period were selected as the control group. Among them, there were 8 males (33.3%, 8/24) and 16 females (66.7%, 16/24). The average age was 23.42±2.54 years. All subjects were examined with the GT-2008V-VI visual electrophysiology instrument of Chongqing Gotec Medical Equipment Limited Company for PERG and FERG. P50 and N95 amplitudes of PERG and PhNR, a wave and b wave amplitudes of FERG were recorded. The peripapillary retinal nerve fiber layer (pRNFL) thicknesses of the nasal, superior, temporal, inferior and average quadrants were measured by spectral domain optical coherence tomography (SD-OCT). The amplitudes of a wave, b wave, PhNR, P50 wave, N95 wave and pRNFL thickness between the three groups were compared by one-way ANOVA. Pearson correlation analysis was used to analyze the correlation between different parameters.Results:Compared with the control group, the amplitudes of PhNR in LHON group and carrier group decreased significantly ( F=11.973, P<0.001). The results of correlation analysis showed that the amplitude of PhNR in LHON group was significantly correlated with the thickness of nasal and temporal pRNFL ( r=0.249, 0.272; P=0.048, 0.030). There was no significant difference in P50 wave amplitude between patients, carriers and controls ( F=1.342, P=0.265). There was no significant difference in N95 wave amplitude between patients and controls ( P=0.960). Conclusion:The PhNR amplitudes of FERG in LHON patients and carriers decrease significantly compared to controls.

Objective:To investigate the characteristics and change trends of electroencephalogram (EEG) in patients with drug resistant epilepsy (DRE) after vagus nerve stimulation (VNS).Methods:Twenty-five patients with DRE, admitted to our hospital from July 2016 to May 2019, were chosen; all patients accepted VNS and followed up for 12 months. Long range video EEG (VEEG) monitoring was performed before VNS, and 3, 6 and 12 months after VNS, and the tracing time of each monitoring was longer than 12 h. The EEG characteristics of these patients before and different times after VNS were analyzed.Results:In the VEEG monitoring before VNS, 25 patients showed sharp wave, spike wave, sharp slow wave, and compound spike slow wave in the interictal period; 3 patients (12%) could locate the brain region. The interictal EEG of 11 patients 3 months after VNS showed different degrees of improvement as compared with the preoperative one, which manifested as mixed rhythms: mono-spiking as sharp wave, sharp slow wave or spike wave; 8 patients had McHugh grading I-II. The interictal EEG of 18 patients 6 months after VNS showed different degrees of improvement as compared with the preoperative one; 11 patients had McHugh grading I-II. The interictal EEG of 21 patients 12 months after VNS showed different degrees of improvement as compared with the preoperative one; 15 patients had McHugh grading I-II.Conclusion:The EEG improvement effect of DRE patients after VNS is gradually improved with time; in some patients, the EEG improvement is earlier than improvement of clinical symptoms.
