Insertion of external ventricular drainage (EVD) is an effective neurosurgical treatment approach. The accuracy of EVD insertion is related to potential complications, and the precise placement of the catheter tip can reduce the incidence of complications. With the progress of medical technology, the research and application of EVD catheterization technology are developing rapidly. This paper reviews the traditional blind catheterization, computed tomography, ultrasound guidance, mixed reality navigation system, laser positioning neural navigation, mobile device neural navigation, stereotactic system, and the visualization technology of the whole process of neuroendoscope assisted ventricle puncture to guide EVD catheterization to provide references for clinical decision-making by medical staff.

OBJECTIVES: Rheumatoid arthritis (RA) imposes a heavy burden on individuals, families, and society. This study analyzed the incidence and mortality trends of RA in China from 1990 to 2023 to provide epidemiological evidence for precise prevention and control. METHODS: Data on RA incidence, age-standardized incidence rate (ASIR), deaths, and age-standardized mortality rate (ASMR) in China by sex and age group from 1900 to 2021 were extracted from the Global Burden of Disease (GBD) 2021 database. Joinpoint regression was used to analyze trends in ASIR and ASMR. An age-period-cohort model was constructed using R4.3.1 to evaluate longitudinal age trends and estimate relative risk (RR) values for period and cohort effects. RESULTS: In 2021, the number of RA cases, ASIR, deaths, and ASMR in China were 247 300, 13.70 per 100 000, 10 300, and 0.54 per 100 000, respectively. From 1990 to 2021, the ASIR of RA increased annually among both females and males, with average annual percentage changes (AAPCs) of 0.44% and 0.72%, respectively. Over the same period, ASMR declined in the total population and among females, with AAPCs of -0.78% and -1.19%, while the change in males was not statistically significant. Age-period-cohort analysis showed that the peak incidence occurred in women aged 60-64 years and men aged 75-79 years, and mortality increased with age. The period effect for incidence rose in both sexes, reaching 1.10 [95% confidence interval (CI) 0.94 to 1.27] for females and 1.14 (95% CI 1.02 to 1.27) for males during 2017 to 2021, compared with 2002 to 2006. The mortality period effect RR exhibited a downward-upward-downward pattern, decreasing to 0.56 (95% CI 0.52 to 0.61) in females and 0.75 (95% CI 0.68 to 0.82) in males in 2017 to 2021. Cohort analysis indicated that the highest incidence risk occurred in individuals born during 2012 to 2016, while the cohort effect RR for female RA mortality showed a continuous decline beginning with the 1922 to 1926 birth cohort. CONCLUSIONS The incidence and mortality risks of RA in China have continued to decline. However, with the aging of the population, the incidence and mortality risks among the elderly have increased. Middle-aged women and elderly men should receive focused attention. Health authorities should strengthen education, prevention, and screening among middle-aged women and enhance disease monitoring in elderly populations to reduce the national burden of RA.

Objective:To explore the effect of combining intermittent θ pulse stimulation (iTBS) of the cerebellum with lower extremity exoskeleton robot support on the balance and walking function of stroke survivors.Methods:Seventy-five stroke survivors complicated with lower extremity dysfunction were divided into an iTBS group, an exoskeleton group and a combined group, each of 25, according to a random number table. In addition to conventional rehabilitation training, the iTBS group was given cerebellar iTBS combined with traditional walking training, the exoskeleton group received sham cerebellar iTBS combined with walking training assisted by a lower extremity exoskeleton robot. The combined group received both therapies. The schedule was once a day, 5 days a week for 3 weeks. Before and after the treatment, the 10-metre walking test (10MWT), the Berg Balance Scale (BBS) and the Fugl-Meyer lower extremity assessment (FMA-LE) were used to evaluate the subjects′ walking ability, balance and lower extremity motor ability. Gait and neuro-electrophysiological tests were also conducted in all three groups.Results:After the treatment, a significant improvement was observed in the 10MWT times, BBS scores, FMA-LE scores, stride frequency and stride speed of all three groups compared with before the treatment. On average, the results of the exoskeleton and combined groups were significantly better than those of the iTBS group, and those of the combined group were significantly better than among the exoskeleton group. Almost everyone′s MEP latency and amplitude had improved significantly compared with before the treatment, but the improvements in the exoskeleton group tended to be superior to those in the iTBS group ( P≤0.05). The latency in the combined group averaged (21.25±1.70)ms, and the amplitude averaged (184.17±6.54)μV, both significantly better than the exoskeleton group′s averages. Conclusions:Cerebellum iTBS combined with lower extremity exoskeleton walker training can significantly improve the motor functioning, balance and walking ability of stroke survivors.

Objective:To explore the effect of combining repeated peripheral (rPMS) and central transcranial magnetic stimulation (rTMS) in treating upper limb motor dysfunction after a stroke.Methods:Seventy-eight patients with upper limb motor dysfunction after a stroke were randomly divided into a control group, an rTMS group and a combined magnetic stimulation group, each of 26. All three groups underwent routine rehabilitation, while the rTMS group was repeatedly given low frequency transcranial magnetic stimulation of the M1 region on the unaffected side, and the combined group also received repeated peripheral magnetic stimulation at Erb′s point on the affected upper limb. There was one treatment session a day, 5 days a week for 3 weeks. Before and after the treatment, everyone′s upper limb motor function was quantified using the Fugl-Meyer upper extremity assessment (FMA-UE) and the Wolf motor function test (WMFT). Skill in the activities of daily living was quantified in terms of a Barthel index (BI). Motor recovery of the upper limbs and hands was assessed using Brunnstrom staging. The latency and amplitude of the motor evoked potentials (MEPs) in the subjects′ affected abductor pollicis brevis muscles were also recorded before and after the treatment. Pearson correlation coefficients quantified the correlation between the changes in FMA-UE scores and MEP amplitudes before and after the treatment in the three groups.Results:There were no significant differences among the three groups before the treatment. Afterward, however, the average FMA-UE, WMFT and BI scores, as well as the upper limb and hand Brunnstrom stages and the average MEP latencies and amplitudes of all the three groups had improved significantly. The combined group′s average results were then significantly better than the other two groups′ averages, except for the upper limb Brunnstrom stages. The increases in MEP amplitude were positively correlated with the increases in FMA-UE scores among the rTMS and the combined group, but there was no significant correlation between them in the control group.Conclusions:The combined application of rPMS and contralateral low frequency rTMS can effectively relieve motor dysfunction in the upper limbs in the early stages after a stroke.

ObjectiveTo investigate growth hormone secretagogue receptor （GHSR） rs2922126 gene polymorphisms and their association with genetic susceptibility to nonalcoholic fatty liver disease （NAFLD） in the Chinese Han population in Qingdao， China， and to provide a basis for diagnosis and treatment. MethodsA total of 220 patients who were admitted to Qingdao Municipal Hospital from June 2022 to June 2023 and were diagnosed with NAFLD based on radiological examination were enrolled as NAFLD group， and 167 healthy individuals during the same period of time were enrolled as control group. Fasting blood samples were collected from all subjects， and related biochemical parameters were measured. Whole blood DNA was extracted， and polymerase chain reaction and MALDI-TOF mass spectrometer were used for genotyping. The chi-square test was used for comparison of categorical data between groups， and the independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between groups. The binary logistic regression analysis was used to investigate the risk of NAFLD. ResultsCompared with the control group， the NAFLD group had significantly higher age， body mass index （BMI）， fasting plasma glucose， triglyceride， gamma-glutamyl transpeptidase， alkaline phosphatase， alanine aminotransferase， and aspartate aminotransferase， as well as a significantly lower level of high-density lipoprotein （all P0.05）. The distribution of GHSR rs2922126 genotypes was consistent with the Hardy-Weinberg equilibrium， suggesting population representativeness in the subjects enrolled （NAFLD group： P=0.106； control group： P=0.849）. There was no significant difference in the distribution of AA， TA， and TT genotypes at GHSR rs2922126 locus between the control group and the NAFLD group （P=0.099）， and there was also no significant difference in allele frequency between the two groups （P=0.063）. In the recessive model of A allele， there was a significant difference in the distribution of AA homozygote and TA+TT genotype between the NAFLD group and the control group （P=0.032）. The binary logistic regression analysis showed that in the recessive model of A allele， AA homozygote carriers had an increased risk of NAFLD compared with TA+TT genotype carriers （odds ratio ［OR］=1.712， 95% confidence interval ［CI］： 1.045 — 2.807， P=0.033）. There was still a significant difference after adjustment for sex， age， and BMI （OR=2.156， 95%CI： 1.221 — 3.808， P=0.008）. In the NAFLD group， AA genotype carriers had a significantly higher serum level of total cholesterol （TC） than TT+TA carriers （Z=-1.99，P=0.046）. ConclusionGHSR rs2922126 AA genotype may be associated with the increased risk of NAFLD in the Chinese Han population in Qingdao， and GHSR rs2922126 AA genotype is associated with the increase in TC in NAFLD patients.

BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

Objective Melatonin has been shown to have neuroprotective effects.This study is aimed at observing the effects of copper deposition on cognitive function in a toxic milk(TX)mouse model of Wilson disease(WD),and investigating the effects and mechanisms of action of Gandou Bushen Decoction(GDBSD)on melatonin synthesis and pineal function in the WD model mice.Methods A total of 30 homozygous TX mice were randomly assigned to 3 groups(n=10 in each group),including a WD group,a GDBSD group,and a dimercaptosuccinic acid(DMSA)group.A total of 10 DL mice were included in the normal control(NC)group.The structure and copper content of pineal gland tissues,oxidative stress and apoptosis-related markers,and serum melatonin levels were evaluated using hematoxylin-eosin(HE)staining,enzyme-linked immunosorbent assay(ELISA),flow cytometry,and Western blot.Results Compared with the NC group,the WD group exhibited decreased learning and cognitive abilities(P＜0.05),damaged pineal gland structure,increased copper content,reactive oxygen species(ROS)levels,and mitochondrial damage rate in the pineal gland(P＜0.01),altered levels of melatonin and oxidative stress-related markers(P＜0.05),upregulated expression levels of pro-apoptotic proteins Bax and Caspase-3,and decreased expression of the anti-apoptotic protein Bcl-2(P＜0.01).After treatment with GDBSD and DMSA,the SIRT3/FOXO3α signaling pathway was activated,the copper content in the pineal gland was reduced,and oxidative stress and apoptosis-related damages were improved,leading to an improvement in learning and memory abilities(P＜0.05).Conclusion GDBSD can alleviate cognitive impairments in WD mice caused by pineal gland copper deposition by inhibiting oxidative stress and apoptosis in the pineal gland.The underlying molecular mechanism is associated with the regulation of the SIRT3/FOXO3α signaling pathway.

Objective:To explore the application value of contrast-enhanced ultrasound (CEUS) combined with transvaginal ultrasound features and quantitative parameters in evaluating high-risk endometrial cancer (EC).Methods:Retrospective analysis was made on 69 EC patients who received CEUS examination and were confirmed by surgery and pathology in Beijing Shijitan Hospital, Capital Medical University from December 2017 to September 2022. According to postoperative pathology, the patients were divided into low-risk group ( n=38) and high-risk group ( n=31). The differences in CEUS, transvaginal ultrasound features and quantitative parameters between the two groups were compared, relevant parameters that with predictive value for high-risk EC were screened, and these parameters were scored. Results:①There were differences in lesion size (thick diameter, long diameter), vascular morphology, and color blood flow score between high and low risk ECs (all P<0.05). ②There were differences in CEUS parameters [perfusion mode, enhancement intensity, area under curve(AUC)] between high and low risk EC groups (all P<0.05). ③The areas under the ROC curve for diagnosing high-risk EC were 0.79, 0.69, 0.69, and 0.62, respectively, based on the critical values of lesion thickness diameter ≥1.85 cm, lesion length diameter ≥2.05 cm, ultrasound contrast quantification parameter AUC ≥859 au, and enhancement intensity ≥29.4 dB. ④Using statistically significant parameters for scoring, the sensitivity and specificity for diagnosing high-risk EC with the score ≥5, were 70.97% and 89.47%, respectively. Conclusions:The combination of CEUS and transvaginal ultrasound is a feasible method for predicting high-risk EC. CEUS parameters (enhanced intensity, AUC, and " focal" perfusion mode) are related to high-risk EC. The combination of CEUS and transvaginal ultrasound helps to pre-evaluate the pathological prognostic factors of endometrial malignant lesions before surgery, providing a basis for clinical follow-up treatment.
