Analysis of factors influencing the frequency of health check-up and health check-up behavior in healthy population / 中华行为医学与脑科学杂志

Objective:To analyze the relevant factors affecting the frequency and behavior of health check-up among the population of medical examinees.Methods:From January to June 2022, 491 health examinees who had health check-ups at the Second Affiliated Hospital of Shandong First Medical University were included.Basic information of the check-up population and their needs for check-up services (form of check-up, content of check-up, cost of check-up, form of feedback on check-up results, and needs for check-up providers) were obtained based on a questionnaire survey.According to the frequency of previous medical check-up, the examinees were divided into never-check-up group (frequency of check-up was 0, n=45), the irregular check-up group (the interval between two physical examinations >1 year, n=49) and the regular check-up group (frequency of check-up=1 year, n=347). The frequency of previous medical check-up was used as the dependent variable, and the age, gender, education level, income, form of medical check-up and cost of medical check-up were used as independent variables to analyse the relevant factors affecting the frequency of their medical check-ups.The above count data were analyzed by one-way analysis using chi-square test, and the count data with statistically significant differences in one-way analysis were analyzed by binary logistic regression.The statistical software was SPSS 21.0. Results:The study included 491 medical examinees, of which 9.16%(45/491) were in the never-check-up group, 20.16%(99/491) in the irregular check-up group and 70.68%(347/491) in the regular check-up group. The impact of demography characteristics of physical examinees on the frequency of health check-up, and there were statistically significant differences in the frequency of health check-up in terms of gender, job, education, and income ( χ2=21.826, 157.113, 104.764, 45.486, all P<0.05). The understanding of health check-up and the attention paid to one's own health were influencing factors that affected the frequency of health check-up. There were statistically significant differences in the frequency of health check-up in necessity of health check-up, attention to one's own health, health check-up forms, health check-up institutions, health check-up price and health check-up contents ( χ2=9.277, 25.863188.239, 59.115, 39.250, 28.314, all P<0.05). Logistic regression analysis showed gender, job type, monthly income, necessity of health check-up, concerns for items of check-up, forms and institutions of check-up were influencing factor of health check-up frequency(all P<0.05). Conclusion:The health check-up behavior of the population and the frequency of regular medical check-ups are influenced by the factors such as gender, education, occupation, income, form of medical check-up, price of medical check-up, choice of medical check-up institution and the degree of concern for one’s own health. The popularisation of health check-ups for special groups such as men, low-income people, low literacy and insufficient awareness of the importance of one’s own health will help improve the overall health awareness of the population.

KCTD4 interacts with CLIC1 to disrupt calcium homeostasis and promote metastasis in esophageal cancer

Increasing evidences suggest the important role of calcium homeostasis in hallmarks of cancer, but its function and regulatory network in metastasis remain unclear. A comprehensive investigation of key regulators in cancer metastasis is urgently needed. Transcriptome sequencing (RNA-seq) of primary esophageal squamous cell carcinoma (ESCC) and matched metastatic tissues and a series of gain/loss-of-function experiments identified potassium channel tetramerization domain containing 4 (KCTD4) as a driver of cancer metastasis. KCTD4 expression was found upregulated in metastatic ESCC. High KCTD4 expression is associated with poor prognosis in patients with ESCC and contributes to cancer metastasis in vitro and in vivo. Mechanistically, KCTD4 binds to CLIC1 and disrupts its dimerization, thus increasing intracellular Ca2+ level to enhance NFATc1-dependent fibronectin transcription. KCTD4-induced fibronectin secretion activates fibroblasts in a paracrine manner, which in turn promotes cancer cell invasion via MMP24 signaling as positive feedback. Furthermore, a lead compound K279-0738 significantly suppresses cancer metastasis by targeting the KCTD4‒CLIC1 interaction, providing a potential therapeutic strategy. Taken together, our study not only uncovers KCTD4 as a regulator of calcium homeostasis, but also reveals KCTD4/CLIC1-Ca2+-NFATc1-fibronectin signaling as a novel mechanism of cancer metastasis. These findings validate KCTD4 as a potential prognostic biomarker and therapeutic target for ESCC.

Research progress in effect of chewing-side preference on temporomandibular joint and its relationship with temporo-mandibular disorders / 浙江大学学报·医学版

Chewing-side preference is one of the risk factors for temporomandibular disorders (TMD), and people with chewing-side preference is more prone to have short and displaced condyles, increased articular eminence inclination and glenoid fossa depth. The proportion of TMD patients with chewing-side preference is often higher than that of the normal subjects. Clinical studies have shown a strong correlation between chewing-side preference and TMD symptoms and signs; and animal studies have shown that chewing-side preference can affect the growth, development, damage and repair of the mandible. After long-term unilateral mastication, changes in the stress within the joint cause the imbalance of temporomandibular joint (TMJ) structural reconstruction, the transformation and even destruction of the fiber structure of masticatory muscle, resulting in uncoordinated movement of bilateral muscles. The joint neurogenic diseases caused by the increase of neuropeptide substance P and calcitonin-gene-related-peptide (CGRP) released locally by TMJ may be the mechanism of TMD. This article reviews the research progress of the influence of chewing-side preference on the structure of TMJ, the relationship between chewing-side preference and TMD, and the related mechanisms.

Objectives:To investigate the antibacterial effects of Acinetobacter baumannii on Acinetobacter SPP. Methods:A Acinetobacter baumannii strain named SL- A.baumannii that can inhibit other Acinetobacter baumannii strains was isolated from the bronchoalveolar lavage fluid of a critically infected patient in the department of neurology, Henan Provincial Hospital on December 10, 2020. To better understand this inhibition effect, the drug resistance, homology and protein fingerprint of the new Acinetobacter baumannii strain, along with 40 other Acinetobacter SPP isolates, were analyzed. Results:Multilocus sequence typing (MLST) revealed that a novel allele combination (gltA/gyrB/gdhB/recA/cpn60/gpi/rpoD) 33, 12, 40, 26, 48, 54, 5 was found in SL- A.baumannii, and ST-2442 was assigned by PubMLST (Oxford). Moreover, 36 isolates, including 30 Acinetobacter baumannii strains, 2 Acinetobacter lwoffii strains, 3 Acinetobacter pittii strains and 1 Acinetobacter ursingii strain, were inhibited by SL- A.baumannii, the inhibition rate was 90% (36/40). Among those strains, 18 (50%) were sensitive to all the antibacterial drugs; 16 (44.44%) showed multi-drug resistance(MDR), including 2 pan-drug resistance(PDR) and 11 extensive drug resistance (XDR) strains; the other 2 (5.56%) were only resistant to Trimethoprim/Sulfamethoxazole(SXT). Conclusion:The new sequence type (ST-2442) Acinetobacter baumannii isolate SL- A.baumannii (PubMLST/Acinetobacter baumannii isolates database/id: 6942) had shown a significantinhibitory effect on Acinetobacter SPP with different drug-resistant phenotypes.

Short term and long-term clinical effects of total hip arthroplasty and hemiarthroplasty on elderly patients with femoral neck fracture / 中国医师杂志

Objective:To investigate the clinical effect and short-term and long-term effect of total hip replacement (THA) and hemiarthroplasty of hip (HA) in elderly patients with femoral neck fracture (FNF).Methods:59 elderly patients with FNF in South District of Guang′anmen Hospital, Chinese Academy of Traditional Chinese Medicine from March 2017 to January 2019 were retrospectively analyzed. The observation group ( n=29) was treated with THA; The control group ( n=30) was treated with HA. The operation related indexes, short-term and long-term clinical effect (average follow-up of 24.1 months), hip function improvement, pain and complications were compared between the two groups. Short term and long-term clinical effects: the short-term and long-term clinical effects of the two groups were observed by the Harris Hip Score (HHS) of the first month, the third month, the sixth month, the ninth month and the first year after operation. Results:Both THA and HA were effective on elderly FNF, but the effective rate of THA (96.6%) was significantly higher than that of HA (90.0%), with statistically significant difference ( P<0.05); in terms of operation related indicators, compared with the control group, the observation group had longer operation time [ (104.46±3.24)min vs (84.34±3.64)min], more amount of bleeding [(296.64±15.16)ml vs (281.44±12.16)ml], lower postoperative drainage volume [(101.24±4.15)ml vs (74.56±3.24)ml], while the functional recovery of the observation group was better than the control group by HHS ( P<0.05); the postoperative complications and HHS score of observation group were significantly lower than the control group ( P<0.05). Conclusions:THA has the advantages of low complication, fast functional recovery and better effect. The clinical decision should be based on the patient′s physical condition. THA should be used for elderly patients with good basic condition, good surgical tolerance and more daily activities. HA should be used for elderly patients with poor basic condition, low surgical tolerance and less daily activities.

ObjectiveTo analyze the association of HLA-DQA1 gene polymorphism with persistent Chlamydia trachomatis genital infection.Methods Blood samples were collected from 80 patients with persistent genital Chlamydial infection,80 patients with common genital Chlamydial infection(who tested negative for Chlamydia trachomatis after one course of standard systemic treatment) and 80 normal human controls.HLA-DQA1 alleles were genotyped by PCR followed by gene sequencing.ResultsThe frequency of HLA-DQA1*0102 allele and HLA-DQA1*0501 allele was 22.5％ and 5.0％ respectively in patients with persistent genital Chlamydial infection,5％ and 20％ respectively in those with common genital Chlamydial infection,2.5％ and 17.5％ respectively in normal human controls.Compared with the patients with common genital Chlamydial infection and controls,the patients with persistent genital Chlamydial infection had a higher frequency of HLA-DQA1*0102(x2 =14.6286,P ＜ 0.001 ),but a lower frequency of DQA1*0501 (x2 =6.2598,P ＜ 0.05).ConclusionsHLA-DQA1*0102 allele may be a susceptible gene or closely linked with the susceptible genes of persistent genital Chlamydial infection.HLA-DQA1*0501 allele may have protective effects against persistent genital Chlamydial infection.

Changes in synaptophysin and growth associated protein-43 mRNA around a cerebral infarction after mobility training / 中华物理医学与康复杂志

Objective To investigate the effects of mobility training on mobility and the mRNA levels of both synaptophysin and growth associated protein 43 (GAP-43) in the region around an infarction in rats with acute cerebral infarction. Methods Models of cerebral infarction were created in 100 rats through middle cerebral artery occlusion. They were then randomly divided into training and control groups. The motor skill of the rats was examined using a beam walking test. The mRNA levels of both synaptophysin and GAP-43 in the region around the infarction were observed at the 1st, 3rd, 7th, 14th and 28th days after model-creation using a semi-quantitive reverse transcrip-tion polymerase chain reaction. Results The rats' mobility scores increased with training, and significant differ-ences were observed between the average scores of the two groups at the 3rd, 7th and 14th days. The scores were higher in the training group. The mRNA levels of both synaptophysin and GAP-43 in the region around the infarction increased significantly from the 1st to the 3rd and 7th days. Synaptophysin mRNA levels were significantly higher in the trained group at each time point, but the levels of GAP-43 mRNA were significantly higher in the trained group only on the 3rd and 7th days. Conclusions Motor skill and the mRNA levels of synaptophysin and GAP-43 in the region around an infarction can be increased by motor skill training, at least in rats with model acute cerebral infarc-tion.

The effect of mild hypothermia on the content of Ca~(2+)、Mg~(2+)、EAA in rat brain tissue and ET in plasma after acute cerebral infarction / 中华物理医学与康复杂志

Objective To investigate the effect of m il d hypothermia on the content of Ca 2+、Mg 2+、EAA in rat brain tissue and ET in plasma after acute cerebral infarction. Methods Forty-eight Sprague-Dawley rats were randomly assigned into trial group and control group. Using the method of reformed line-thrombosis,the cerebral in farction models were established. The rats in the trial-group were cooled by mi ld hypothermia for half an hour, while those in the control group were subjected to no disposal. Every group was divided into 4 sub-groups according to the pos t-infarction disposal time. Every sub-group was composed of 6 SD rats and kill ed at the time points of 1 hour,2 hour,4 hour and 8 hour after infarction, respe ctively. Then the content of Ca 2+、Mg 2+、EAA in rat brain tissue an d ET in plasma were measured. ResultsThe post-infar ction content of Ca 2+、EAA and ET of trial-group increased mildly and Mg 2+ reduced very little. There was a significant statistical difference bet ween the trial group and the control group. Conclusion Mild hypothermia may significantly reverse the increase of the content of Ca 2+ and EAA and the fall of Mg 2+ and the increment of ET in plasma as well after acute cerebral infarction in experimental animals. So as a result, m ild hypothermia possesses protective effect on brain.
