OBJECTIVE: To compare the clinical efficacy of acupuncture with yin-yang regulation method versus local acupuncture in treating chronic low back pain (CLBP) in elderly patients with lumbar disc herniation (LDH), and to evaluate the changes in the multifidus muscle before and after treatment using musculoskeletal ultrasound. METHODS: A total of 128 elderly patients with CLBP due to LDH were randomly assigned to an observation group (64 cases, 2 cases dropped out) and a control group (64 cases, 2 cases dropped out). The control group received local acupuncture at bilateral L₃-L₅ Jiaji points (EX-B2), Shenshu (BL23), Dachangshu (BL25), Weizhong (BL40), Yaoyangguan (GV3), and ashi points. The observation group received acupuncture with yin-yang regulation method, which included an abdominal protocol with Baihui (GV20), Zhongwan (CV12), Qihai (CV6), Guanyuan (CV4), bilateral Tianshu (ST25), and Dahe (KI12), etc., and a lumbar protocol with Baihui (GV20), Dazhui (GV14), Jizhong (GV6), Yaoyangguan (GV3), and ashi points, etc., alternated bilaterally. Both groups were treated once every other day, three times per week, for a total of 12 sessions. The visual analogue scale (VAS) score, Oswestry disability index (ODI) score, and the indexs of musculoskeletal ultrasound multifidus muscle (resting and functional thickness and Young's modulus values) were observed before and after treatment, and the clinical efficacy was evaluated in the two groups. RESULTS: After 1 and 4 weeks of treatment, both groups showed lower VAS scores compared to baseline (P<0.05), the VAS scores in the observation group were lower than those in the control group (P<0.001). ODI scores in both groups were decreased after 1 and 4 weeks of treatment compared to baseline (P<0.05), with a further reduction at 4 weeks of treatment compared to 1 week of treatment (P<0.05); the observation group showed lower ODI score than the control group after 1 week of treatment (P<0.001). After treatment, both groups demonstrated increased resting and functional multifidus muscle thickness bilaterally compared to baseline (P<0.01), with an increased right-side thickness change rate (P<0.01), though no significant difference was observed between groups (P>0.05). Compared to baseline, after treatment, the observation group exhibited decreased Young's modulus values for bilateral resting and functional multifidus muscle (P<0.01), while the control group showed reductions only in bilateral resting and right-side functional Young's modulus values (P<0.01). After treatment, the bilateral functional Young's modulus values in the observation group were lower than that in the control group (P<0.05), and the bilateral resting and functional changes in Young's modulus values were greater in the observation group than those in the control group (P<0.01). The overall effective rate was 93.5% (58/62) in the observation group, which was higher than 79.0% (49/62) in the control group (P<0.05). CONCLUSION Acupuncture with yin-yang regulation method effectively alleviates pain, improves functional disability, increases multifidus muscle thickness, and reduces Young's modulus values in elderly patients with CLBP due to LDH, which has superior therapeutic effect compared to local acupuncture.

ObjectiveTo explore the compliance related factors of repeated screening for colorectal cancer in Jiading District， and to provide a scientific basis for the prevention and control of colorectal cancer. MethodsBased on the natural population cohort in Jiading District， and the screening situation in 2017‒2019 and 2020‒2022， the study subjects were divided into the groups of never participating in screening and participating in screening. Subjects in the participating group were further divided into participating in one round of screening or having repeated screening. SPSS 21.0 software was used to analyze the demographic characteristics of each group. χ² test or Fisher precise probability test were used to conduct univariate analysis of the factors such as gender， age， education level， marital status， retirement status， and type of medical insurance. Factors with the significant difference （P<0.05） were selected for inclusion in multivariate analysis， and factors related to compliance with repeated screening were analyzed by multivariate logistic regression. ResultsA total of 8 179 subjects were included in the study， including 3 323 males （40.6%） and 4 856 females （59.4%）. The average age of the subjects was （61.26±6.06） years old. A total of2 652 （32.4%） had educated in primary school or below， 4 242 （51.9%） in secondary school， and 1 285 （15.7%） in higher secondary school. Mostly， 7 579 （92.7%） were married. Among the participants， 4 062 people had never participated in screening， 4 117 people had participated in screening， and 1 485 of them had repeated screening， with a repeated screening rate of 18.2%. Multivariate logistic regression analysis showed that women had better compliance with repeated screening than men （OR=1.31， 95%CI： 1.14‒1.50）. Compared with the population aged 50 to 54 years， the population aged 55‒59 years （OR=1.57， 95%CI： 1.19‒2.08）， 60-64 years （OR=2.77， 95%CI： 2.13‒3.61）， and 65-69 years （OR=3.31， 95%CI： 2.51‒4.36） had higher compliance with repeated screening. Compared with employees' medical insurance， residents' medical insurance group had worse compliance with repeated screening （OR=0.76， 95%CI： 0.66‒0.87）. People with a history of intestinal polyps were more likely to undergo repeat screening than those without （OR=2.07， 95%CI： 1.50‒2.87）. ConclusionCompliance with repeated screening for colorectal cancer still needs to be improved， and there are differences in compliance with repeated screening for different populations with different characteristics. Identifying groups that are unlikely to adhere to community-based colorectal cancer screening and taking targeted interventions can help improve the continued compliance of residents with colorectal cancer screening.

ObjectiveTo explore the research status and hot spots of virtual reality in the field of stroke rehabilitation. MethodsThe literature related to the application of virtual reality technology in stroke rehabilitation was retrieved in CNKI and Web of Science core collection from establishiment to August, 2024. The knowledge map of authors, institutions and keywords was drawn by Citespace 6.2.R7. ResultsA total of 485 papers were retreived, including 201 in Chinese and 284 in English. The number of articles published in both Chinese and English was on the rise. Qu Yun was the Chinese author with the most articles, and Rocco Salvatore Calabro was the English author. The Third Affiliated Hospital of Sun Yat-Sen University and IRCCS Bonino Pulejo published the most papers respectively. The results of keyword co-occurrence and clustering were consistent in the Chinese and English keywords, mainly included hemiplegia, balance function, upper limb function and cognitive function. The keywords with high bursting intensity in Chinese included motor function, cognitive function and upper limb function, while those with high bursting intensity in English included upper limb, cognitive impairment and environment. The hot spots in this field focused on the virtual reality technology for stroke patients' motor function rehabilitation, cognitive function rehabilitation, limb function rehabilitation and virtual reality technology combined with conventional treatment. ConclusionVirtual reality technology, as a simulation information technology, has been widely applied in the fields of motor function rehabilitation, cognitive function rehabilitation and limb function rehabilitation for stroke patients. The combination of virtual reality technology with conventional rehabilitation therapy could enhance the functional level and activities of daily living. More researches may focus on conjunctions of virtual reality technology with new technologies such as digital therapeutics and brain-computer interfaces, to improve the gait and upper limb functions of stroke patients.

Myeloid neoplasms (MNs) belong to a group of hematological malignancies characterized by the abnormal biological functions of hematopoietic stem progenitor cells. The abnormal immune and hematopoietic microenvironment of patients with MN interact with malignant clonal hematopoietic stem cells, promoting the occurrence and development of their diseases. MN large granular lymphocyte proliferation (MN-LGLP) is a special and rare clinical phenomenon in this type of disease. Currently, research on this disease in domestic and international cohorts is limited. This study analyzes the clinical and laboratory characteristics of this type of patient and explores the impact of LGLP on the clinical characteristics and survival of patients with MN. Patients with MN-LGLP are prone to neutropenia and splenomegaly. The presence of LGLP is not a risk factor affecting the survival of patients with MN-LGLP. STAG, ASXL1, and TET2 are the most common accompanying gene mutations in MN-LGLP, and patients with MN-LGLP and STAG2 mutations have poor prognoses.

Objective To investigate the expression of long non-coding RNA(lncRNA),surfactant associated 1 pseudogene(SFTA1P)in lung squamous carcinoma and its effect on the biological functions of SFTA1P in lung squamous carcinoma cell lines.Methods Based on the cancer genome atlas(TCGA)database,the differential expression of SFTA1P in tumor and normal tissues were compared in patients diagnosed with lung squamous cell carcinoma.Then,the expression of SFTA1P was detected in human normal lung epithelial cell line BEAS-2B and lung squamous cell lines SK-MES-1 and H520 with real-time quantitative polymerase chain reaction(RT-qPCR).SK-MES-1 and H520 cells with overexpression and/or knockdown of SFTA1P were constructed by transfecting the overexpression plasmids(pcDNA3.1-SFTA1P)and small interfering RNAs(si-SFTA1P-1 and si-SFTA1P-2).CCK-8 assay and Transwell assay were used to investigate the effect of SFTA1P on biological functions in lung squamous carcinoma cells.Differential gene expression analysis,correlation analysis and functional enrichment analysis were employed to explore the potential mechanism that SFTA1P may affect biological functions of lung squamous cells.Results Analysis of TCGA showed that the expression of SFTA1P was significantly lower in lung squamous cell carcinoma tissue than adjacent normal tissue(P＜0.05).RT-PCR results showed that the expression of SFTA1P was obviously lower in lung squamous carcinoma cells than the human normal lung epithelial cells(P＜0.05).And the expression level of SFTA1P was relatively lower in the SK-MES-1 cells than the H520 cells(P＜0.05).Overexpression of SFTA1P suppressed the proliferation,migration and invasion of lung squamous carcinoma cells(P＜0.05),while its knockdown promoted these abilities(P＜0.05).Differential gene expression analysis,correlation analysis and functional enrichment analysis indicated that SFTA1P may inhibit MYC,G2m checkpoints and E2f signaling pathways in lung squamous cell carcinoma.Conclusion SFTA1P shows anti-cancer function in lung squamous cell carcinoma,and it may affect the biological functions of lung squamous cell carcinoma cells through down-regulating MYC,G2m checkpoints and E2f signaling pathways.

Objective:To explore the standardization of totally implantable venous power port of nursing process in CT enhancement and application effect of contrast medium injection, so as to provide a safer and more efficient way for contrast medium injection in CT enhanced examination for patients with malignant tumors.Methods:A non-randomized prospective study was conducted, 358 patients with malignant tumors were selected in Sun Yat-sen Memorial Hospital, Sun Yat-sen University who underwent CT enhanced examination from August 1, 2022 to July 31, 2023, 179 patients who had been implanted totally implantable venous power port were selected as the experimental group, and the standardized nursing procedure was given. The other 179 patients were the control group, using radiology routine high-pressure intravenous indwelling needle as the contrast medium access, with routine peripheral venous nursing process. The incidence of contrast medium extravasation during CT enhanced examination was observed and compared between the two groups.Results:All the patients were included. There were 85 males and 94 females, aged (55.50±11.72) years old in the control group. There were 83 males and 96 females, aged (54.50±12.24) years old in the experimental group. The incidence of contrast medium extravasation was 0 in the experimental group and 3.35%(6/179) in the control group. The difference between the two groups was statistically significant (Fisher exact probability, P<0.05). Conclusions:The application of standardized nursing procedure of totally implantable venous power port to the injection of contrast medium in CT enhanced examination of malignant tumor patients, can significantly reduce the incidence of contrast medium extravasation.

Objective:To investigate the clinical effect of intraarticular vancomycin on early periprosthetic joint infection (PJI) in knee arthroplasty and the incidence of postoperative complications.Methods:This is a retrospective cohort study. The clinical data of 1 867 patients who underwent primary knee arthroplasty at Department of Joint Surgery, the Affiliated Hospital of Qingdao University from April 2022 to June 2023 were retrospectively analysed, including total knee arthroplasty (TKA), robotic-assisted total knee arthroplasty (RA-TKA) and unicondylar knee arthroplasty (UKA). There were 687 males and 1 180 females, aged (68.0±11.2)years(range:45 to 87 years). Patients were divided into the vancomycin group and the control group according to whether or not intra-articular injection of 1 g of vancomycin powder dissolved in 30 ml of saline was performed after intraoperative joint capsule closure. In the vancomycin group, 925 patients were included, including 782 TKA, 27 RA-TKA and 116 UKA.In the control group, 942 patients were included, including 767 TKA, 99 RA-TKA and 76 UKA. Early PJI, wound complications, and vancomycin-related toxicity including acute renal collapse, ototoxicity, and allergic reactions were assessed within 3 months postoperatively. The data were compared using the independent sample t test, χ2 test, and Fisher's exact probability method, as appropriate. Major Extremity Trauma Research Consortium (METRC). Results:No PJI was found in all patients in the vancomycin group.Five cases (0.7%,5/767) of early PJI were found in TKA patients in the control group, with a statistically significant difference ( P=0.030); 1 case of early PJI was found in each RA-TKA and UKA patients, with non-significant difference compared with vancomycin group (all P>0.05). Two cases (0.3%,2/782) of incisional complications were found in TKA patients in the vancomycin group, and 4 cases (0.5%, 4/767) of incisional complications were found in TKA patients in the control group, with non-significant difference( P=0.449); no incisional complication was found in RA-TKA patients in the vancomycin group, and 1 case (1.0%,1/99) of incisional complications were found in RA-TKA patients in the control group, the difference was not statistically significant ( P>0.05); no incisional complication was found in both groups of UKA patients.No vancomycin-related acute kidney injury, ototoxicity, or allergic reactions was observed in all patients. Conclusion:Intra-articular injection of 1 g of vancomycin suspension after arthrotomy closure during TKA maybe lower the risk of early PJI without increasing the risk of wound complication and vancomycin-associated systemic toxicity.

Objective:To explore the influence of perceived stress on bedtime procrastination in college students,as well as the mediating role of daily ego-depletion and the moderating effect of guilt.Methods:The Per-ceived Stress Scale(PSS-4),State Self-Control Scale(SSCCS)and Bedtime Procrastination Scale(BPS)were used to track the daily perceived stress,ego-depletion and sleep procrastination of 34 college students for 14 days.The 1-1-1 and 2-1-1 multi-layer linear models were constructed by HLM to test the mediating and mod-erating effects.Results:Daily ego-depletion scores played a mediating role in the influence of daily perceived stress scores on daily bedtime procrastination scores(γ20=0.49,P＜0.001),guilt scores moderated the effect of daily ego-depletion scores on daily bedtime procrastination scores(γ11=0.03,P＜0.05).Conclusion:Daily perceived stress could not only directly predict bedtime procrastination on the night in college students,but also indirectly af-fect daily bedtime procrastination through daily ego-depletion.When ego-depletion is high,guilt can reduce college students'bedtime procrastination.

In recent years, researchers have found that patients with nonalcoholic fatty liver disease (NAFLD) often have urolithiasis, and the incidence of urolithiasis increases gradually with the severity of NAFLD. Meanwhile, the detection rate of NAFLD was higher in patients with urolithiasis than in normal controls. In this paper, we reviewed the domestic and international studies on the correlation between urolithiasis and NAFLD and described the related pathogenesis, such as insulin resistance, oxidative stress, abnormal lipid metabolism and impaired glyoxalate detoxification. Meanwhile, this paper proposed preventive measures to reduce the risk of development and recurrence of NAFLD-associated urolithiasis by addressing the common risk factors of both diseases, including metabolism-related diseases, lifestyle and diet.
