Objective:To determine the weight coefficient of home care service quality indicators for the disabled elderly in Beijing.Methods:In the early stage, our research group has preliminarily constructed quality indicators of home care service for the disabled elderly in Beijing. The importance scores of all indicators were obtained through expert consultation from September to October 2021. Based on the game theory, the subjective and objective weighting methods were integrated to quantify the combinatorial optimization weight assignment of those indicators, in which the subjective weighting was calculated by proportional distribution method, and the objective weighting was obtained by entropy weight method.Results:The subjective weight assignments of the first-level indicators “service conditions”“service process” and “service outcome”were 0.332 2, 0.338 9, and 0.328 9, respectively; the objective weight assignments of the above indicators were 0.332 2, 0.338 9 and 0.328 9, respectively; the combinatorial optimization weight assignment of those indicators were 0.332 2, 0.338 9, and 0.328 9, respectively. Among the second-level indicators, the combination optimization weight coefficients of the top 3 important indicators “patient family evaluation”(1.3),“emergency configuration”(1.4), and“operation process”(2.2) were 0.198 4, 0.198 4 and 0.170 8, respectively. And among the third-level indicators, the combination optimization weight coefficients of the top 5 important indicators“emergency plan”(1.4.1), “humanistic care”(2.2.6), “first aid supplies”(1.4.2), “evaluation of potential resources”(1.3.4), and “means of home visit transportation”(1.2.1) were 0.124 7, 0.075 0, 0.073 8, 0.066 5 and 0.052 7, respectively.Conclusion:The study has successfully conducted the optimization weight assignment of home care service quality indicators for the disabled elderly in Beijing, which indicates that the service conditions and service process are crucial to the quality of service.

Objective:To investigate the effects of lezumab adjuvant therapy on the degree of retinal vasculopathy and immune response in the treatment of macular central diabetic retinopathy (DR).Methods:From July 2022 to December 2023, 120 patients with DR in macular central who received treatment in the Xi′an People′s Hospital (Xi′an Fourth Hospital) were retrospectively selected and divided into two groups according to the treatment methods: the observation group (60 cases, lezumab combined with sitagliptin), and the control group (60 cases, sitagliptin). Patients′glucose metabolism, visual acuity, degree of retinopathy, inflammation [tumor necrosis factor-alpha (TNF-α), interleukin-2 (IL-2), interleukin-10 (IL-10)] and angiogenesis related factors [serum vascular endothelial growth factor (VEGF), midkine (MK), 5′-nucleotidase (CD73)] were evaluated, and the curative efficacy of the two groups was compared. The security of the two schemes was compared.Results:Compared with the control group, the serum concentrations of MK, CD73, TNF-α and VEGF were lower in the observation group after treatment: (1.44 ± 0.06) ng/L vs. (1.67 ± 0.11) ng/L, (1.10 ± 0.27) ng/L vs. (1.31 ± 0.26) ng/L, (11.62 ± 0.89) ng/L vs. (15.96 ± 4.42) ng/L, (84.07 ± 27.07) ng/L vs. (100.72 ± 16.05) ng/L, while the concentration of IL-10 was higher: (65.65 ± 8.68) ng/L vs. (60.02 ± 5.07) ng/L, with statistically significant differences ( P<0.05). There were no statistically significant differences in fasting blood glucose (FBG) and 2 h postprandial blood glucose between two groups before and after treatment ( P>0.05). After treatment, the macular thickness and visual field gray value in the observation group were lower than those in the control group: (302.81 ± 77.08) μm vs. (336.44 ± 10.35) μm, (1.55 ± 0.43)% vs. (2.09 ± 0.51)% ( P<0.05). After 3 months of treatment, the visual acuity in the observation group was higher than that in the control group: 0.493 ± 0.103 vs. 0.439 ± 0.084 ( P<0.05). No serious adverse reactions occurred in both groups. Conclusions:Lezumab assisted sitagliptin has a significant effect in the treatment of DR, which can reduce the degree of lesions, improve vision, and reduce the levels of inflammation and angiogenesis related factors.

Objective:To develop an indicator system for defining the health services provided by family doctors within the "Healthy Subdistrict" initiative in China.Methods:An initial set of indicators was developed through literature review and qualitative research, followed by the design of an expert consultation questionnaire. Twenty-one experts with extensive experience in community family doctor services in Beijing were selected. Two rounds of Delphi consultations were conducted via email between December 2024 and February 2025. Expert demographics and authority coefficients were collected and the indicator system was finalized.Results:The response rate was 100% for both rounds. The average expert authority coefficient ( Cr) was 0.860 (range: 0.700-1.000). Kendall′s W for importance and feasibility increased from 0.129 and 0.196 in the first round to 0.230 and 0.268 in the second round (all P<0.001), indicating strong consensus. The final system includes 5 first-level and 23 second-level indicators, categorized as: Integrated Preventive and Clinical Care Services, Healthy Community Promotion Services, Basic Medical Services, Public Health Services, and Services for Promoting Equity in Citizen Health and Well-being. The highest-weighted first-level indicators were Basic Medical Services (0.281) and Integrated Preventive and Clinical Care Services (0.281), followed by Services for Promoting Equity in Citizen Health and Well-being (0.191), Healthy Community Promotion Services (0.124), and Public Health Services (0.124). All indicators had importance and feasibility scores above 3.5. Conclusion:This study establishes a weighted indicator system to guide and evaluate the health services provided by family doctors within the "Healthy Subdistrict" initiative, clarifying key service priorities.

Objective To measure the distance between the lateral compression Ⅱ(LC-Ⅱ)screw guide needle and the surrounding important structures around the anterior inferior iliac spine in pelvic fractures and to locate the needle point,so as to provide anatomical reference for clinical nail placement.Methods Totally 40 adult gross specimens of embalming were implanted with LC-Ⅱ screw guide needle under the surveillance of C-arm machine,and the specimens were dissected.The shortest distance between the insertion point and the lateral femoral cutaneous nerve,femoral nerve,femoral artery,femoral vein,anterior superior iliac spine and inguinal ligament was measured.The triangle was constructed between the insertion point,anterior superior iliac spine and inguinal ligament,and the exact location of the entry point was calculated.Results The average distance between the insertion point of the male needle and the femoral vein was(50.67±7.29)mm＞the anterior superior iliac spine(43.83±7.58)mm＞the femoral artery(38.35±6.63)mm＞the femoral nerve(31.17±1.67)mm=the inguinal ligament(28.69±6.59)mm＞the lateral femoral cutaneous nerve(7.98±3.81)mm.The mean distance between the insertion point of the female needle and the anterior superior iliac spine was(45.28±7.07)mm=femoral vein(43.72±6.89)mm＞femoral artery(33.76±6.33)mm＞femoral nerve(25.66±6.46)mm=inguinal ligament(23.22±5.00)mm＞lateral femoral cutaneous nerve(8.97±4.76)mm.The projection distance of the entry point was 31.77 mm for men and 38.41 mm for women.The Angle b was 42.81°for men and 31.71° for women.Conclusion The lateral femoral cutaneous nerve is most vulnerable to injury when LC-Ⅱ screw is inserted,and the risk of injury has nothing to do with sex.The insertion point positioning method a and b made LC-Ⅱ screw placement quickly,safely and accurately,and reduced fluoroscopy time and frequency.

AIM: To explore the correlation between the integrity of the macular microstructures and the visual outcomes before and after idiopathic macular epiretinal membrane(IMEM)surgery.METHODS: A total of 43 patients(43 eyes)with IMEM who were treated in our hospital between January 2017 and December 2019 were selected. The best corrected visual acuity(BCVA)of each patient was examined preoperatively and at 3, 6, 9mo after surgery. Moreover, metamorphopsia(M-chart)examination was given, and spectral domain-optical coherence tomography(SD-OCT)was used to measure central foveal thickness(CFT), subfoveal choroidal thickness(SFCT), the thickness of ganglion cells-inner plexiform layer(GC-IPL)and the length of interdigitation zone(IZ)defect.RESULTS: The BCVA and the metamorphopsia were gradually improved at postoperative 3, 6 and 9 mo(all P<0.05). Moreover, the BCVA was positively correlated with CFT and the length of the IZ defect(P<0.05), while it was not correlated with SFCT and the thickness of GC-IPL(P>0.05). The metamorphopsia assessment was positively correlated with the CFT at postoperative 3, 6, and 9mo(P<0.05), while it was not correlated with SFCT, the thickness of GC-IPL and the length of IZ defect(P>0.05).CONCLUSIONS: The CFT and the length of IZ defect were significantly correlated with the BCVA after IMEM surgery, which can be used as indicators to predict the recovery of visual function after IMEM surgery.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

OBJECTIVE: To explore the clinical and laboratory characteristics of 5 patients with myeloid leukemia and t(12;22)(p13;q12). METHODS: Bone marrow cells were cultured for 24 h and analyzed by standard R-banding. Rearrangement of the MN1 gene was detected by fluorescence in situ hybridization (FISH) using dual color break-apart MN1 probes. MN1-ETV6 and ETV6-MN1 fusion genes were detected by reverse transcription polymerase chain reaction (RT-PCR). And the products were subjected to direct sequencing. RESULTS: Among the 5 patients, 2 had AML-M0, 2 had AML-M4, and 1 had CMML at the initial diagnosis. t(12;22)(p13;q12) was the primary abnormality among all patients. Rearrangements of MN1 gene were detected by FISH in all patients. MN1-ETV6 and ETV6-MN1 fusion genes were detected respectively in 4 and 3 patients. CONCLUSION t(12;22)(p13;q12) is a rare but recurrent chromosomal abnormality in myeloid leukemia, and is related to poor prognosis. allo-SCT is valuable for patients with t(12;22)(p13;q12).
