BackgroundChronic insomnia disorder has become a significant public health issue， and it may be associated with dyslipidemia. Previous studies on dyslipidemia in patients with chronic insomnia disorder have mainly focused on exploring the relationship between subjective short sleep duration and dyslipidemia， while there have been limited studies on the relationship between objective short sleep duration and dyslipidemia. ObjectiveTo explore the relationship between objective short sleep duration and dyslipidemia in patients with chronic insomnia disorder， in order to provide references for the prevention and intervention of dyslipidemia in this population. MethodsA total of 103 patients who were hospitalized at The Third Hospital of Mianyang from August 2022 to November 2023 and met the diagnostic criteria for chronic insomnia disorder as defined in the International Classification of Sleep Disorder， third edition （ICSD-3） were retrospectively collected. The objective sleep duration of the patients was obtained through polysomnography. The patients were divided into two groups based on their objective sleep duration： the group with objective sleep duration ≥ 7 hours （n=71） and the group with objective sleep duration < 7 hours （n=32）. Binary Logistic regression analysis was used to explore the impact of objective sleep duration < 7 hours on dyslipidemia. ResultsAmong 103 patients with chronic insomnia disorder， 59 cases （57.28%） were identified with dyslipidemia. The comparison of dyslipidemia conditions between the group with objective sleep duration ≥ 7 hours and the group with objective sleep duration < 7 hours showed a statistically significant difference （χ²=5.956， P<0.05）. Compared with the group with objective sleep duration ≥7 hours， the group with objective sleep duration < 7 hours exhibited significantly lower high-density lipoprotein cholesterol levels， and reduced sleep efficiency （t=-2.003， -5.482， P<0.05 or 0.01）. Binary Logistic regression analysis results showed that the risk of abnormal blood lipids in patients with chronic insomnia disorder with objective sleep duration < 7 hours was 3.128 times higher than that of patients with objective sleep duration ≥ 7 hours （OR=3.128， 95% CI： 1.139–8.588）. ConclusionObjective short sleep duration may be a risk factor for dyslipidemia in patients with chronic insomnia disorder.

Primary splenic lymphoma is a rare malignant neoplasm， with similar clinical manifestations to Sjogren’s syndrome and liver cirrhosis， which often leads to misdiagnosis. This article reports a case of primary splenic lymphoma misdiagnosed as Sjogren’s syndrome with liver cirrhosis， in order to improve the understanding of primary splenic lymphoma， Sjogren’s syndrome， and liver cirrhosis and avoid misdiagnosis and treatment delay.

BackgroundInternet addiction poses serious harm to the physical and mental health of college students. Insecure attachment is one of the key factors of internet addiction， while self-compassion and psychological resilience serve as crucial psychological factors closely related to it. However， the chain mediating role of self-compassion and psychological resilience between insecure attachment and college students' internet addiction remains unclear. ObjectiveTo explore the mediating role of self-compassion and psychological resilience in the relationship between insecure attachment and internet addiction in college students， so as to provide references for the prevention and intervention of internet addiction in this population. MethodsFrom November 2023 to February 2024， a total of 1 380 college students were recruited using a cluster sampling method from two universities in Sichuan Province. The assessment was conducted using the Chinese Internet Addiction Scale （CIAS）， the Self-Compassion Scale （SCS）， the Experiences in Close Relationships Scale （ECR）， and the Resilience Scale for Chinese Adolescents （RSCA）. Pearson correlation analysis was conducted to examine the correlations of the scores of each scale. Model 6 in Process 4.2 was used to test the mediating roles of self-compassion and psychological resilience in the relationship between insecure attachment and internet addiction among college students. ResultsA total of 1 232 （89.28%） college students completed the valid questionnaire survey. The ECR score was positively correlated with the CIAS score （r=0.299， P<0.01）， and SCS score was positively correlated with the RSCA score （r=0.299， P<0.01）. The ECR score was negatively correlated with both SCS score and RSCA score （r=-0.122、-0.147，P<0.01）； the SCS score was negatively correlated with both RSCA score and CIAS score （r=-0.238、-0.263， P<0.01）. Self-compassion and psychological resilience were the pathways between insecure attachment and internet addiction， with effect sizes of 0.015 （95% CI： 0.007–0.023） and 0.010 （95% CI： 0.004–0.017）， respectively. Self-compassion and psychological resilience played chain mediating role between insecure attachment and internet addiction， with effect sizes of 0.003 （95% CI： 0.001–0.006）. ConclusionInsecure attachment can directly affect internet addiction in college students， and it can also influence internet addiction through independent pathway of self-compassion and psychological resilience， as well as the chain mediating pathways involving both self-compassion and psychological resilience.

Ruxolitinib， a small molecule inhibitor， selectively targets Janus kinase （JAK） by competitively binding to adenosine triphosphate on the catalytic site of the JAK1 and JAK2 domain， thereby inhibiting JAK activation and signal transducer and activator of transcription （STAT） phosphorylation and prevents the expressions of the JAK-STAT signaling pathway. Oral ruxolitinib has demonstrated promising efficacy for myelofibrosis and polycythemia vera. The topical Ruxolitinib cream， approved by the US FDA as the first non-segmental vitiligo home treatment drug， is set to be launched in domestic medical pioneer areas in August 2023 and is expected to bring about a breakthrough in the treatment of vitiligo. Clinical cases have also shown that Ruxolitinib cream has significant curative effects on atopic dermatitis， alopecia areata， and other conditions， indicating great application prospects.

Objective:To investigate the methylation status of SDC2, PPP2R5C and ADHFE1 genes in stool and their values in the screening of colorectal cancer and precancerous lesions.Methods:From August 2020 to March 2021, 64 patients with colorectal cancer, 72 patients with adenoma, 33 patients with hyperplastic polyps and 59 healthy people were recruited from Qingdao Central Hospital Affiliated to Qingdao University, and the morning stool samples were collected from the research subjects. The genomic DNA was extracted and modified with sulfite. The methylation status of SDC2, PPP2R5C and ADHFE1 genes were detected by methylation specific polymerase chain reaction (MSP), and the fecal occult blood test (FOBT) was performed. Taking the pathological results as the gold standard, receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to compare the effect of combined detection of methylation of three genes and FOBT in predicting colorectal cancer and precancerous lesions. R-Studio software was used to construct a nomogram for the prediction of colorectal cancer with combined detection of gene methylation in stool and other clinical features, and the calibration and validation were performed.Results:The positive rates of combined detection of methylation of SDC2, PPP2R5C and ADHFE1 genes in stool were higher than those of FOBT in colorectal cancer+adenoma [74.3% (101/136) vs. 47.1% (64/136), χ2 = 23.20, P = 0.001], colorectal cancer [90.6% (58/64) vs. 70.3% (45/64), χ2 = 8.91, P = 0.003] and adenoma [59.7% (43/72) vs. 26.4% (19/72), χ2 = 14.43, P = 0.002]. There was no significant difference in the positive rates in hyperplastic polyps [21.2% (7/33) vs. 6.1% (2/33), χ2 = 0.12, P = 0.125] and healthy controls [10.2% (6/59) vs. 8.5% (5/59), χ2 = 4.01, P = 1.000]. The combined detection of gene methylation was better than FOBT in the prediction of colorectal cancer + adenoma [AUC: 0.85 (95% CI 0.80-0.91) vs. 0.71 (95% CI 0.64-0.78), P < 0.05], especially in the prediction of adenoma [AUC: 0.82 (95% CI 0.74-0.89) vs 0.64 (95% CI 0.57-0.69), P < 0.001]. The sensitivity and specificity of ADHFE1 gene methylation status in predicting colorectal cancer were high (90.6% and 96.6%). In colorectal cancer patients over 50 years old, the positive rate of combined detection of gene methylation was higher than that of FOBT [90.2% (55/61) vs. 68.9% (42/61), P < 0.05]. The nomogram calibration curve for predicting colorectal cancer constructed based on the combined detection of gene methylation and each clinical feature showed a high degree of concordance between the predicted and observed diagnostic performance of colorectal cancer. Conclusions:The methylation levels of SDC2, PPP2R5C AND ADHFE1 genes in stool are increased in patients with colorectal cancer or adenoma. The combined detection of gene methylation is expected to be a non-invasive method for the screening of colorectal cancer and precancerous lesions.

Objective:To evaluate the role of nucleotide-binding oligomerization domain-2 (NOD2) in dorsal root ganglion in the development of neuropathic pain (NP) in rats.Methods:Thirty-two adult male SPF Sprague-Dawley rats, weighing 240-260 g, aged 2-3 months, were divided into 4 groups ( n=8 each) using a random number table method: control group (group C), NP group (group S), negative control siRAN group (group N), and NOD2-siRNA group (group R). In N and R groups, 1×10 8 IFU/ml negative control siRNA and NOD2-siRNA 10 μl were intrathecally injected, respectively, once a day for 3 consecutive days.Normal saline 10 μl was intrathecally injected once a day for 3 consecutive days in C and S groups.The model of NP was established using spared nerve injury (SNI) at 2 weeks after intrathecal injection.The mechanical paw withdrawal threshold (MWT) was measured at 1 day before surgery and 1, 3, 7, 10, 14 and 28 days after SNI.Animals were sacrificed after measuring pain threshold on day 28, and the dorsal root ganglions (DRGs) of the lumbar segment (L 4-6) were removed for determination of the expression of NOD2 (by Western blot) and expression of tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β), IL-6 and NOD2 mRNA (using quantitative real-time polymerase chain reaction). Results:Compared with group C, MWT was significantly decreased at each time point after SNI, and the expression of NOD2 protein and mRNA and TNF-α, IL-1β and IL-6 mRNA in DRGs was up-regulated in group NP ( P<0.01). Compared with group NP, MWT was significantly increased at each time point after SNI, and the expression of NOD2 protein and mRNA and TNF-α, IL-1β and IL-6 mRNA in DRGs was down-regulated in group R ( P<0.01), and no significant change was found in the parameters mentioned above in group N ( P>0.05). Conclusion:The mechanism underlying the development of NP may be related to the up-regulation of NOD2 expression in DRGs, thus further promoting the expression of pro-inflammatory factors in rats.

Objective:Based on the data of Global Burden of Disease 2019 data, to analyze the past, current, and future burden of disability-adjusted life years (DALYs) in China and compare with the international status.Methods:The total number of DALYs, age-standardized DALY rate, and the composition of different subgroups were extracted and described to analyze the time trend in 2000-2019 and the current situation in 2019 for Chinese female breast cancer. The burden of DALYs in 2050 was predicted by Joinpoint using average annual percent change (AAPC).Results:In 2000-2019, the ranking of DALYs caused by female breast cancer in China rose from the fourth to the second in all female cancers. The total DALYs increased by 48.4%, of which the years lived with disability increased from 4.8% to 8.8%. The age-standardized DALY rate only slightly decreased (AAPC=-0.3%; which increased during 2016-2019, AAPC=1.6%). In 2019, the age-standardized DALY rate for breast cancer in China was 278.0/100 000. The DALYs were 2.88 million (accounting for 14.2% of the global burden and 12.1% of all female cancers burden in China), 26.5% of which attributed known risk factors (overweight and obesity were the largest: 0.34 million DALYs, but some common breast cancer risk factors were not available on the platform, such as menstruation and fertility). In 2050, the prediction suggests that the total DALYs caused by female breast cancer in China will reach 3.80 million person-years-5.16 million person-years, increasing 32.1%-79.4% over 2019. From 2000 to 2019, the peak age of DALYs and DALY rate became older, and the DALYs among females aged 65 years and above increased faster than those younger than 65 years (AAPC were 4.8% and 1.3%, respectively). In 2019, females aged 45-74 (the starting age recommended by local guidelines for breast cancer screening) contributed 74.3% of the total DALYs.Conclusions:Over the past 20 years, the age-standardized DALY rate for breast cancer in female populations in China has not changed obviously. Without the continuous expansion of effective intervention and population aging, the burden of DALYs for female breast cancer in China will increase. DALYs for breast cancer attributed leading risk factors were still limited.

Objective:To evaluate the efficacy and safety profile of ixazomib/lenalidomide/dexamethasone (IRd) in Chinese patients with relapsed/refractory multiple myeloma (MM) .Methods:This study comprising 14 medical centers in China included patients with relapsed/refractory MM who received at least. Ixazomib at an initial oral dose of 4 mg was administered. Seven patients had dose adjustment to 3 mg at the time of first dose. The lenalidomide doses were adjusted according to creatinine clearance rate. The efficacy and safety were evaluated every cycle.Results:In the study cohort of 74 patients, the median age was 65 years and 11 (14.9% ) patients received over three lines of therapy. Overall response rate (ORR) was 54.1% (40/74) , and 7 (9.5% ) , 14 (18.9% ) , and 19 (25.7% ) patients achieved stringent complete response or complete response, very good partial response, and partial response, respectively. The median progression-free survival and overall survival were 9.9 and 20 months, respectively. The median time to response was 1 month. The efficacy and survival outcome were similar to those reported in the Tourmaline-MM1 China Continuous Study. The ORR of patients refractory to bortezomib, lenalidomide, and bortezomib plus lenalidomide were 52.0% (13/25) , 57.1% (4/7) , and 33.3% (6/18) , respectively. The rate of grade 3-4 adverse events was 36.5% (27/74) . Common hematological toxicities were anemia, thrombocytopenia, lymphopenia, and neutropenia. Common non-hematological toxicities were fatigue, gastrointestinal symptoms, and infections. Two cases of grade 3 peripheral neuropathy were reported. The patients eligible for the Tourmaline-MM1 China Continuous Study had a higher ORR than the ineligible patients [77.8% (14/18) vs 46.4% (26/56) , P=0.020]. There was no difference in the rate of grade 3-4 adverse events [33.3% (6/18) vs 37.5% (21/56) , P=0.749]. Conclusion:The IRd regimen had good efficacy and acceptable toxicity in Chinese patients with relapsed/refractory MM.

PURPOSE: Rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone administered every 3 weeks (R-CHOP-21) is the standard care for diffuse large B-cell lymphoma (DLBCL). It is unknown whether the dose-dense R-CHOP (R-CHOP-14) could improve the outcome of the disease in Asian population. MATERIALS AND METHODS: Newly diagnosed DLBCL patients were centrally, randomly assigned (1:1) to receive R-CHOP-14 or R-CHOP-21. R-CHOP-14 was administered every 2 weeks, and R-CHOP-21 was administered every 3 weeks. Primary end point was disease-free survival (DFS). Secondary end points included overall survival (OS), progression-free survival (PFS), response rate and toxicities. RESULTS: Seven hundred and two patients were randomly assigned to receive R-CHOP-14 (n=349) or R-CHOP-21 (n=353). With a median follow-up of 45.6 months, the two groups did not differ significantly in 3-year DFS (79.6% for R-CHOP-14 vs. 83.2% for R-CHOP-21, p=0.311), 3-year OS (77.5% for R-CHOP-14 vs. 77.6% for R-CHOP-21, p=0.903), or 3-year PFS (63.2% for R-CHOP-14 vs. 66.1% for R-CHOP-21, p=0.447). Patients with an International Prognostic Index (IPI) score ≥ 2 had a poorer prognosis compared to those with an IPI score < 2. Grade 3/4 hematologic and non-hematologic toxicities were manageable and similar between R-CHOP-14 and R-CHOP-21. CONCLUSION: R-CHOP-14 did not improve the outcome of DLBCL compared to R-CHOP-21 in Asian population. With manageable and similar toxicities, both of the two regimens were suitable for Asian DLBCL patients. For high-risk patients with IPI ≥ 2, new combination regimens based on R-CHOP deserve further investigation to improve efficacy.
