OBJECTIVE: To investigate the expression and clinical significance of interleukin-10 (IL-10) and interleukin-15 (IL-15) in patients with multiple myeloma (MM). METHODS: Eighty newly diagnosed MM patients in Department of Hematology in Nanyang First People's Hospital from September 2020 to January 2023 were selected as observation group, and 80 healthy people in our hospital were selected as control group. The expression of IL-10 and IL-15 of the two groups were detected, and survival analysis was conducted for the MM patients. RESULTS: The levels of IL-10 and IL-15 in the observation group before treatment were significantly higher than those in the control group (both P <0.05). The levels of IL-10 and IL-15 in different DS stage had significant differences in MM patients (both P <0.05). The levels of IL-10 and IL-15 in stage II and stage III had no significant differences, which were both significantly higher than those in stage I (both P <0.05). The levels of IL-10 and IL-15 in sCR+CR group after treatment were significantly lower than those before treatment (both P <0.05). The levels of IL-10 and IL-15 in VGPR+PR group after treatment were also significantly lower than those before treatment (both P <0.05), but higher than those in the sCR+CR group (both P <0.05). The progression-free survival (PFS) and overall survival (OS) of patients with IL-10>22.01 pg/ml were significantly shorter than those with IL-10≤22.01 pg/ml (both P <0.001). The PFS and OS of patients with IL-15>48.56 pg/ml were also shorter than those with IL-15≤48.56 pg/ml (both P <0.05). CONCLUSIONS The levels of IL-10 and IL-15 in MM patients are closely related to efficacy and prognosis, and both decreased after treatment. The more reduction, the better effect. Patients with IL-10 and IL-15 below the threshold have longer median PFS and OS.

OBJECTIVE: To analyze the MYH9 gene sequence of a patient with hereditary thrombocytopenia and diffuse large B-cell lymphoma and his family members, and to explore the relationship between MYH9 gene and tumors. METHODS: Peripheral blood samples were collected from the patients and their family members for complete blood count analysis. The platelet morphology was observed under microscope. The MYH9 gene sequence was analyzed by Whole Exon Sequencing and Sanger Sequencing. RESULTS: The mutation site c.279C>A:p.(Asn93Lys) in exon 2 of the MYH9 gene were found in patient and his family members, both presenting as thrombocytopenia. The platelet count was significantly increased after the administration of Avatrombopag. CONCLUSION A novel mutation of MYH9 was found in this study, and the case was sensitive to Avatrombopag, by exploring the relationship between the MYH9 gene and tumors, suggesting that the MYH9 gene may be associated with the development of diffuse large B-cell lymphoma.

BACKGROUND: The association of systemic inflammatory response index (SIRI) with prognosis of coronary artery disease (CAD) patients has never been investigated in a large sample with long-term follow-up. This study aimed to explore the association of SIRI with all-cause and cause-specific mortality in a nationally representative sample of CAD patients from United States. METHODS: A total of 3386 participants with CAD from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were included in this study. Cox proportional hazards model, restricted cubic spline (RCS), and receiver operating characteristic curve (ROC) were performed to investigate the association of SIRI with all-cause and cause-specific mortality. Piece-wise linear regression and sensitivity analyses were also performed. RESULTS: During a median follow-up of 7.7 years, 1454 all-cause mortality occurred. After adjusting for confounding factors, higher lnSIRI was significantly associated with higher risk of all-cause (HR = 1.16, 95% CI: 1.09-1.23) and CVD mortality (HR = 1.17, 95% CI: 1.05-1.30) but not cancer mortality (HR = 1.17, 95% CI: 0.99-1.38). The associations of SIRI with all-cause and CVD mortality were detected as J-shaped with threshold values of 1.05935 and 1.122946 for SIRI, respectively. ROC curves showed that lnSIRI had robust predictive effect both in short and long terms. CONCLUSIONS SIRI was independently associated with all-cause and CVD mortality, and the dose-response relationship was J-shaped. SIRI might serve as a valid predictor for all-cause and CVD mortality both in the short and long terms.

Objective:To investigate the feasibility and effectiveness of three-dimensional visualization technology in the precise diagnosis and treatment of locally advanced differentiated thyroid cancer(DTC).Methods:A retrospective analysis was conducted on the clinical data of 196 patients with locally advanced DTC treated at the 960th Hospital of the PLA from December 2021 to August 2023. The cohort included 71 male and 125 female patients, with a mean age of 43.7 years (rangd from 18 to 77 years). All patients underwent neck-enhanced CT scans and were divided into two groups: the study group( n=102), which underwent preoperative three-dimensional visualization of CT data, and the control group( n=94), which did not. Baseline data for both groups were matched using SPSS27.0 with 1∶1 propensity score matching (PSM) and the caliper value was 0.02. A total of 49 patients were included in each group, including 35 first-time surgeries and 14 reoperation. Among the 70 first-time surgeries, 29 patients underwent robotic surgery and 41 underwent open surgery. Among the 28 reoperations, 4 underwent robotic surgery and 24 underwent open surgery. In the study group, three-dimensional visual models were used to comprehensively evaluate the tumor and metastatic lesion size, spatial location, and adjacent relationship with surrounding organs, surgical treatments were guided by these models, whereas the control group relied on two-dimensional imaging for guidance. The clinical data were statistically analyzed using SPSS27.0. Results:All operations were successfully completed. There were no statistical differences in baseline data between the two groups( P>0.05). Among first-time surgeries, the study group showed shorter operation times [175(145, 200) min vs 205(182, 249) min, P<0.001], a lower incidence of postoperative chyle leak (0 vs 8.57%, P=0.027), a higher rate of robotic surgery (48.57% vs 34.28%, P=0.225), a greater number of harvested lymph nodes [46(40, 62) vs 37(28, 56), P=0.032], a greater number of cervical lymph node metastasis[15(7, 22) vs 5(1, 14), P=0.004] and a larger diameter of metastasis lymph nodes[12(10, 16) mm vs 4(1, 10) mm, P<0.001]. There were no significant differences in intraoperative blood loss, postoperative drainage days and incidence of hypoparathyroidism( P>0.05). During the reoperation, the study group had shorter operation times[103.5(95.0, 122.5) min vs 146.50(133.25, 172.25) min, P<0.001], less intraoperative blood loss[12.50(8.75, 22.50) mL vs 30.00(17.50, 35.00) mL, P=0.021], fewer postoperative drainage days[5.00(4.00, 6.00) d vs 6.00(5.00, 7.25) d, P=0.016] and a lower incidence of hypoparathyroidism(7.14% vs 42.86%, P=0.038).The robotic surgery rate was higher in the study group (21.42% vs 7.14%, P=0.596). There were no significant differences in lymph node dissection numbers, metastatic lymph node counts, or chyle leak incidences between the two groups ( P>0.05). No acute bleeding or incision infection occurred in any patient postoperatively. Conclusion:Three-dimensional visualization technology is an effective preoperative assessment method for evaluating the resectability of tumors and metastases lesions in locally advanced DTC. It enhances the accuracy and safety of surgery for locally advanced DTC.

Objective To assess the risk factors for carbapenem-resistant Acinetobacter baumannii(CRAB)bloodstream infection(BSI)and 28-day short-term mortality in elderly patients,and provide reference for the pre-vention and treatment of CRAB BSI.Methods Clinical data of patients aged ≥60 years and diagnosed with AB BSI in a hospital in Yulin City from January 2013 to December 2022 were retrospectively analyzed,including demogra-phic and microbiological characteristics,as well as clinical outcomes of the patients.Variables which were significant in univariate analysis were selected for multivariate analysis using binary logistic regression model and Cox propor-tional hazards model.Independent risk factors for infection were further determined,and survival analysis was per-formed using Kaplan-Meier curve.Results A total of 150 patients were included in the study,out of which 16 pa-tients(10.7％)had CRAB BSI and 134 had carbapenem-sensitive AB(CSAB)BSI.The 28-day short-term mortali-ty of AB BSI in elderly patients was 15.3％(23/150,95％CI:9.6％-21.1％),and the short-term mortality of CRAB BSI was higher than that of CSAB([56.3％,9/16]vs[10.4％,14/134]).Deep venous catheterization(OR:15.598,95％CI:1.831-132.910)and combined infections of other sites(OR:15.449,95％CI:1.497-159.489)were related to CRAB BSI in elderly patients.The independent risk factors for 28-day mortality in elderly patients with AB BSI were hemodialysis(OR:11.856,95％CI:2.924-48.076),intensive care unit admission(OR:9.387,95％CI:1.941-45.385),and pulmonary infection being suspected source of bacteremia(OR:7.019,95％CI:1.345-36.635).Conclusion The occurrence of CRAB BSI in elderly patients is related to the combined infection of other sites and deep vein catheterization.Hemodialysis,admission to ICU,and pulmonary infection being suspected source of bacteremia are independent risk factors for the prognosis of AB BSI in elderly patients.

The assessment of adverse drug events is an important basis for clinical safety evaluation and post-marketing risk control of drugs,and its causality assessment is gaining increasing attention.The existing methods for assessing the causal relationship between drugs and the occurrence of adverse reactions can be broadly classified into three categories:global introspective methods,standardized methods,and probabilistic methods.At present,there is no systematic introduction of the operational details of the various methods in the domestic literature.This paper compares representative causality assessment methods in terms of definition and concept,methodological steps,industry evaluation and advantages and disadvantages,clarifies the basic process of determining the causality of adverse drug reactions,and discusses how to further improve the adverse drug reaction monitoring and evaluation system,with a view to providing a reference for drug development and pharmacovigilance work in China.

Osteosarcopenia (OS) is a multifactorial, multiaetiologic degenerative metabolic syndrome in which sarcopenia coexists with osteoporosis, and its influences are related to aging-induced mechanics, genetics, inflammatory factors, endocrine disorders, and irregular lifestyles. With the accelerated aging process in our country, osteosarcopenia has become a public health problem that cannot be ignored, with a higher risk of falls, fractures, impaired mobility and death. In recent years, scholars at home and abroad have conducted a lot of research on osteosarcopenia, but their pathogenesis is still unclear. Understanding the signaling pathways associated with osteosarcopenia is of great significance for further research on the pathogenesis of these disorders and for finding new targets for treatment. Studies have shown that activation of the PI3K/Akt signaling pathway promotes osteoblast differentiation as well as skeletal muscle regeneration, indicating that inhibition of thePI3K/Akt signaling pathway is closely related to the development of osteosarcopenia. Muscle factor-mechanical stress interactions can maintain osteoblast viability by activating the Wnt/β-catenin signaling pathway, suggesting that Wnt signaling is important in muscle and bone crosstalk. The Notch signaling pathway also plays an important role in improving bone and muscle mass and function, but different researchers hold different views, which need to be further validated and refined in subsequent studies. Exercise, as an existing non-pharmacological treatment with strong and sustained effects on physical function and muscle strength, also significantly increases bone density in osteoporosis patients, which may be mainly due to the fact that exercise induces changes in the form and function of bones, in the form of muscular pulling and indirectly improves the bone mass, and changes in the bone strength can also change the number, shape as well as the function of the muscles. At the same time, the mechanism of different exercise modalities focuses on different aspects, and there are differences in exercise time, exercise intensity, and therapeutic effects in the implementation of interventions. Aerobic exercise can improve the quality of skeletal muscle and increase the expression of osteogenesis-related genes by stimulating mitochondrial biosynthesis, as well as improve the quality and strength of bones and muscles through the Wnt/β- catenin and PI3K/Akt signaling pathways, effectively preventing and controlling the occurrence of musculoskeletal disorders. High-intensity resistance exercise has a significant effect on improving the quality of muscles and bone mineral density, but older people with osteosarcopenia suffer from a decline in muscle quality and strength, and a decline in bone mineral density, which makes them very susceptible to fracture, so they should select the intensity of the training in a gradual and orderly manner, from small to large. What kind of exercise intensity and exercise modalities are most effective in improving the occurrence and development of osteosarcopenia needs to be further investigated. Therefore, this paper mainly reviews the epidemiology of osteosarcopenia, diagnostic criteria, the related signaling pathways (PI3K/Akt pathway, Wnt/β-catenin pathway, Notch pathway, NF-κB pathway) that jointly regulate the metabolic process of myocytes and skeletal cells, as well as the interventional effects of different exercise modes on osteosarcopenia, with the aim of providing theoretical bases for the clinical treatment of osteosarcopenia, as well as enhancing the preventive capacity of the disease in old age.

Objective:To review the outcome of intravitreous anti-vascular endothelial growth factor (VEGF) treatment in patients with X-linked retinoschisis (XLRS) complicated with vitreous hemorrhage (VH).Methods:A retrospective clinical study. From March 1, 2016 to April 1, 2022, 18 patients (19 eyes) diagnosed with XLRS complicated with vitreous hemorrhage in Beijing Tongren Hospital, Capital Medical University of Eye Center were included. All the patients were male, with a median age of 7.05±3.8 years. Best corrected visual acuity (BCVA) and wide-angle fundus photography were performed in all the patients. BCVA was carried out using international standard visual acuity chart, and converted into logarithm of minimum resolution angle (logMAR) in statistics analysis. According to whether the patients received intravitreal injection of ranibizumab (IVR), the patients were divided into injection group and observation group, with 11 eyes in 10 cases and 8 eyes in 8 cases, respectively. In the injection group, 0.025 ml of 10 mg/ml ranibizumab (including 0.25 mg of ranibizumab) was injected into the vitreous cavity of the affected eye. Follow-up time after treatment was 24.82±20.77 months. The VH absorption time, visual acuity changes and complications were observed in the injection group after treatment. Paired sample t test was used to compare BCVA before and after VH and IVR treatment. Independent sample t test was used to compare the VH absorption time between the injection group and the observation group. Results:LogMAR BCVA before and after VH were 0.73±0.32 and 1.80±0.77, respectively. BCVA decreased significantly after VH ( t=-3.620, P=0.006). LogMAR BCVA after VH and IVR were 1.87±0.55 and 0.62±0.29, respectively. BCVA was significantly improved after IVR treatment ( t=6.684, P<0.001). BCVA records were available in 5 eyes before and after IVR, and the BCVA values after VH and IVR were 0.58±0.31 and 0.48±0.20, respectively, with no statistically significant difference ( t=1.000, P=0.374). BCVA increased in 1 eye and remained unchanged in 4 eyes after treatment. BCVA records were available in 5 eyes before VH and after VH absorption in the 8 eyes of the observation group. LogMAR BCVA before VH and after VH absorption were 0.88±0.28 and 0.90±0.26, respectively, with no significant difference ( t=-1.000, P=0.374). After VH absorption, BCVA remained unchanged in 4 eyes and decreased in 1 eye. The absorption time of VH in the injection group and the observation group were 1.80±1.06 and 7.25±5.04 months, respectively. The absorption time of VH was significantly shorter in the injection group than in the observation group, the difference was statistically significant ( t=-3.005, P=0.018). Multivariate linear regression analysis showed that IVR treatment was significantly correlated with VH absorption time ( B=-6.66, 95% confidence interval -10.93--2.39, t=-3.40, P=0.005). In the injection group, VH recurrence occurred in 1 eye after IVR treatment. Vitrectomy (PPV) was performed in one eye. In the 8 eyes of the observation group, VH recurrence occurred in 2 eyes, subsequent PPV in 1 eye. The rate of VH recurrence and PPV was lower in the injection group, however, the difference was not statistically significant( P=0.576, 1.000). In terms of complications, minor subconjunctival hemorrhage occurred in 2 eyes and minor corneal epithelial injury occurred in 1 eye in the injection group, and all recovered spontaneously within a short time. In the injection group, 9 eyes had wide-angle fundus photography before and after IVR treatment. There was no significant change in the range of peripheral retinoschisis after treatment. No obvious proliferative vitreoretinopathy, infectious endophthalmitis, retinal detachment, macular hole, complicated cataract, secondary glaucoma or other serious complications were found in all the treated eyes, and there were no systemic complications. Conclusion:Intravitreous anti-VEGF treatment may accelerate the absorption of vitreous hemorrhage in patients with XLRS. No impact is found regarding to the peripheral retinoschisis.
