Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

Objective:To validate the validity of the auricular cartilage fish-shaped framework in comprehensive rhinoplasty for Chinese Han females.Methods:The clinical data of Chinese Han female patients with short nose and saddle nasal deformity undergoing primary rhinoplasty at the Department of Plastic Surgery, the First Affiliated Hospital of Nanchang University, from August 2021 to October 2023, were retrospectively analyzed. Patients underwent comprehensive rhinoplasty, involving the implantation of an auricular cartilage fish-shaped framework at the nasal tip and a dorsal nasal implant on the nasal bridge.Postoperative follow-up monitored for complications. At 6-month postoperatively, a satisfaction survey was conducted among the patients, their family, or friends using a scale where: very satisfied with improvement=4, moderately satisfied with improvement=3, Slightly satisfied with improvement=2, No improvement=1. Additionally, two plastic surgeons evaluated the postoperative outcomes using a scale where: excellent=5, very good=4, good=3, fair=2, poor=1.Preoperative and 6-month postoperative photographs were processed using Image J software to measure the following parameters: nasolabial angle, nasofacial angle, nasofrontal angle, columellar lobular angle, nasal height, and nasal length. Paired t-tests were used for statistical analysis, with P < 0.05 considered statistically significant. Results:A total of 18 patients were included, with a mean age of (26.4 ± 7.2) years (range: 18-45 years). The mean postoperative follow-up duration was (23.0 ± 9.3) months (range: 6 months to 3 years). All patients recovered well, with no severe complications occurring.The mean patient satisfaction score regarding the postoperative outcome was 3.50 ± 0.62. The mean satisfaction score from family or friends was 3.33 ± 0.69. The two evaluating plastic surgeons rated the outcomes as 4.17 ± 0.85 and 3.94 ± 0.93, respectively, both falling between the excellent and very good categories on the assessment scale.Statistically significant differences (all P < 0.01) were found between preoperative and 6-month postoperative measurements for all assessed nasal parameters. Nasolabial angle: 99.68° ± 2.95° vs. 95.37° ± 1.09°; nasofacial angle: 29.47° ± 2.99° vs. 32.82° ± 2.23°; nasofrontal angle: 140.72° ± 5.18° vs. 133.79° ± 4.43°; columellar lobular angle: 44.86° ± 3.43° vs. 39.23° ± 6.44°; nasal height: (57.52 ± 0.60) mm vs. (58.41 ± 0.39) mm; nasal length: (50.08 ± 0.54) mm vs. (50.64 ± 0.31) mm. Conclusion:The use of the auricular cartilage fish-shaped framework combined with a prosthesis in rhinoplasty, requiring only unilateral or bilateral auricular cartilage, effectively improved low nose and short nose deformities in the majority of Chinese Han females. This validates the favorable outcome of this framework in comprehensive rhinoplasty for this population.

Objective: To investigate the status and influencing factors of platelet bacterial contamination in China, and to provide theoretical support for relevant policies in blood collection and transfusion institutions. Methods: A meta-analysis by systematically searching studies on platelet bacterial contamination in China published between 1998 and 2023 was conducted. Data analysis was performed using R4.4 software to combine studies that met the inclusion criteria. Results: Twenty-three studies were included after screening. The combined analysis showed that the overall contamination rate of platelets in China was 0.18% (95% CI: 0.12%-0.24%). The contamination rate of manually condensed platelets was significantly higher than that of apheresis platelet concentrates (0.28% vs 0.17%, P<0.01). No significant difference in platelet contamination rates was found between eastern and central regions (0.21% vs 0.15%, P>0.01). The contamination rate of aerobic bacteria was higher than that of anaerobic bacteria (0.11% vs 0.06%, P<0.01). Publication bias analysis indicated robust results, and sensitivity analysis showed minimal impact of excluding individual studies on the overall conclusion. Conclusion: Although the platelet contamination rate in China is generally low, significant differences exist across collection methods and regions.

Objective To investigate the effect of an intelligent telerehabilitation developed with reinforcement theory on the postoperative functional recovery and return to sport in patients after reconstructive surgery of anterior cruciate ligament.Methods By using the convenience sampling method,120 patients after reconstructive surgery of anterior cruciate ligament at a tertiary general hospital in Wuhan from June 2022 to June 2023 were selected as the research subjects.Sixty patients admitted to our hospital between June 2022 and December 2022 were assigned to a control group,while another 60 patients admitted to our hospital between January 2023 and June 2023 were assigned to an trial group.The patients in the control group received conventional surgical treatment,nursing care and instructions for rehabilitation,whereas additional rehabilitation based on the intelligent telerehabilitation developed with reinforcement theory was given to the patients in the trial group.The two groups were compared in terms of postoperative knee function and compliance with rehabilitation exercise.Results The compliance of the trial group with home rehabilitation training was higher than that of the control group.The comparison between the two groups showed a statistically significant difference(P<0.05).12 months after surgery,patients in the trial group exhibited higher scores in International Knee Documentation Committee Subjective knee form(IKDC)and Lysholm and Gillquist knee scores compared with those in the control group(both P<0.05.Also,the patients in trial group showed lower incidences of pain,swelling and joint instability compared with those in the control group(all P<0.05).At 12 months after surgery,the patients in trial group showed better capability to perform daily activities and participate in sports in comparison with those in the control group(both P<0.05).Conclusion The intelligent telerehabilitation based on reinforcement theory can improve the compliance of patient with rehabilitation.It therefore is able to reduce incidences of postoperative complications such as pain,swelling,knee instability and locking in patients who had the surgery for reconstruction of anterior cruciate ligament.It also enhances the function recovery of knee,and helps patients to resume the activities in life and sports.

Objective To explore the effects of preoperative transcatheter arterial chemoembolization(TACE)on early postoperative recurrence in the China liver cancer(CNLC)staging Ⅰb-Ⅱa patients with primary hepatocellular carcinoma.Methods The data of patients with CNLC Ⅰb-Ⅱa stage hepatocellular carcinoma who underwent curative liver resection in Xiangyang Central Hospital from May 2017 to May 2022 were retrospectively analyzed.A total of 76 patients were included,patients were divided into preoperative TACE group(n=32)and surgery group(n=44)according to whether they underwent preoperative TACE.Observe the postoperative recovery of patients.Combined with the postoperative pathological results,adjuvant TACE treatment is performed.Regular reexamination and follow-up are conducted after discharge.The Kaplan-Meier method was used to estimate survival time,calculate 95％CI,and plot the Disease-free(DFS)survival curve.The Cox proportional risk model was used for univariate and multivariate analysis.Results The 1-year disease-free survival rate in the preoperative TACE group was higher than that in the direct surgery group(96.9％vs.84.1％,P＞0.05).The 2-year disease-free survival rate in the preoperative TACE group was higher than that in the direct surgery group(90.6％vs.70.5％,P＜0.05).The disease-free survival of the preoperative TACE group was higher than the direct surgery group(23.03 months vs.20.14 months,P＜0.05).The incidence of treatment-related adverse events after surgery in the preoperative TACE group was higher than that in the direct surgery group(34.4％vs.20.5％,P＞0.05).Multivariate Cox regression analysis showed that different treatment methods,tumor number ≥ 2,and tumor microvascular invasion were prognostic factors affecting tumor recurrence.No severe adverse reactions occurred in either group,and no deaths caused by adverse reactions were observed.Conclusion Compared with direct surgery,preoperative TACE can help improve early postoperative recurrence,prolong patients'disease-free survival,and do not lead to serious adverse events.

Objective To investigate the clinical efficacy of wrapping the hepatic artery with the hepatogastric ligament for preventing bleeding of the hepatic artery and its branches following pancreaticoduodenectomy(PD).Methods 194 patients who underwent PD in Xiangyang Central Hospital from January 2017 to November 2024 were enrolled and categorized into two groups based on whether the hepatic artery was enwrapped with the hepatogastric ligament during the operation.The wrapped group consisted of 95 cases where the hepatic artery was wrapped,while the non-wrapped group had 99 cases without such wrapping.Intraoperative parameters(intraoperative blood loss and operative time)and postoperative complications(pancreatic fistula,abdominal cavity infection,biliary fistula,delayed gastric emptying,postoperative bleeding,and bleeding of the hepatic artery and its branches)were compared between the two cohorts.Univariate and multivariate Logistic regression analyses were conducted to identify the independent risk factors for postoperative bleeding.Results PD was accomplished successfully in both groups.There was no remarkable difference in intraoperative indices like blood loss and operative time between the two groups(P＞0.05).Similarly,no significant disparities were noted in postoperative complications such as pancreatic fistula,abdominal infection,biliary fistula,and delayed gastric emptying(P＞0.05).Nevertheless,the incidence of postoperative bleeding in the wrapped group was lower than that in the non-wrapped group(3.16％vs.12.12％,P=0.019),and the incidence of bleeding of the hepatic artery and its branches after surgery was also significantly decreased in the wrapped group(0 vs.10.10％,P=0.004).Logistic regression analysis revealed that the operation time(OR=1.013,P=0.011),pancreatic fistula(OR=9.006,P=0.006)and celiac infection(OR=7.930,P=0.014)are independent risk factors of postoperative bleeding,Hepatogastric ligament encapsulation of hepatic artery was an independent protective factor for postoperative hemorrhage of PD(OR=0.084,P=0.006).Conclusion Wrapping the hepatic artery with the hepatogastric ligament reduces PD postoperative bleeding,especially that of the hepatic artery and its branches,without adding other complications.
