Objective To compare the efficacy and safety of computed tomography (CT)-guided percutaneous versus electromagnetic navigation bronchoscopy (ENB)-guided microwave ablation (MWA) for the treatment of pulmonary nodules. Methods A retrospective analysis was conducted on the data of high-risk pulmonary nodule patients who underwent MWA at the Nanjing Drum Tower Hospital between 2022 and 2023. The pathological diagnosis rate, complications, and progression-free survival (PFS) rate were compared between the CT group and the ENB group. Results There were 61 patients in the CT group, including 30 males and 31 females, with an average age of (67.22±9.13) years. There were 53 patients in the ENB group, including 29 males and 24 females, with an average age of (65.29±13.76) years. The pathological diagnosis rate in the CT group was slightly higher than that in the ENB group (88.52% vs. 71.69%, P=0.03). However, the ENB group exhibited a lower incidence of perioperative complications, including pneumothorax (16.39% vs. 3.77%, P=0.03), hemoptysis (19.67% vs. 5.66%, P=0.05), and pain (22.95% vs. 7.55%, P=0.03). There was no statistically significant difference in PFS rate between the two groups [HR=1.17, 95%CI (0.23, 5.81), P=0.85]. Conclusion Both CT-guided and ENB-guided MWA are effective treatment modalities for high-risk pulmonary nodules.

Objective:To discuss the infection status and clinical outcomes in the patients with bullous pemphigoid(BP),and to analyze the risk factors for infection in hospitalized BP patients,as well as to construct and evaluate the risk prediction model.Methods:A total of 126 patients first diagnosed with BP were selected.According to the occurrence of infection,the patients were divided into infection group(52 cases)and non-infection group(74 cases).The infection status and outcomes of the patients in two groups were recorded;statistical analysis was performed on the general data,laboratory examination results,FRAIL scale scores for frailty screening,NRS2002 scores,and skin lesion severity of the patients in two groups;multivariate Logistic regression model was used to identify the risk factors for infection in the patients;the goodness-of-fit test was used to evaluate the model;receiver operating characteristic(ROC)curve was used to evaluate the predictive value of the model for infection.Results:Among the 126 hospitalized BP patients,52 cases had infection,with an infection rate of 41.27％.The mortality rate of the patients in infection group was higher than that in non-infection group(P＜0.05),and the remission rate of the patients in non-infection group was higher than that in infection group(P＜0.05).The FRAIL scale score for frailty screening,NRS2002 score,serum albumin level,prealbumin level,number of hospitalization,skin lesion severity,and time of hospital stay of the patients in infection group were significantly higher than those in non-infection group(P＜0.05).The multivariate Logistic regression analysis results derived the regression equation:Logistic(P)=-7.63+0.922× skin lesion severity+2.565×FRAIL scale score for frailty screening+1.214×NRS2002 score.The area under the curve of the Logistic regression model was 0.916.Conclusion:The FRAIL scale score for frailty screening,NRS2002 score,and skin lesion severity are the risk factors for infection in the hospitalized BP patients.The constructed infection risk prediction model based on these factors has good predictive value and may provide new ideas for the prevention and control of infection in the hospitalized BP patients.

Objective: This study aimed to determine the predictive performance of non-contrast CT (NCCT) signs for hemorrhagic growth after intracerebral hemorrhage (ICH) when stratified by onset-to-imaging time (OIT). Materials and Methods: 1488 supratentorial ICH within 6 h of onset were consecutively recruited from six centers between January 2018 and August 2022. NCCT signs were classified according to density (hypodensities, swirl sign, black hole sign, blend sign, fluid level, and heterogeneous density) and shape (island sign, satellite sign, and irregular shape) features. Multivariable logistic regression was used to evaluate the association between NCCT signs and three types of hemorrhagic growth: hematoma expansion (HE), intraventricular hemorrhage growth (IVHG), and revised HE (RHE). The performance of the NCCT signs was evaluated using the positive predictive value (PPV) stratified by OIT. Results: Multivariable analysis showed that hypodensities were an independent predictor of HE (adjusted odds ratio [95% confidence interval] of 7.99 [4.87–13.40]), IVHG (3.64 [2.15–6.24]), and RHE (7.90 [4.93–12.90]). Similarly, OIT (for a 1-h increase) was an independent inverse predictor of HE (0.59 [0.52–0.66]), IVHG (0.72 [0.64–0.81]), and RHE (0.61 [0.54– 0.67]). Blend and island signs were independently associated with HE and RHE (10.60 [7.36–15.30] and 10.10 [7.10–14.60], respectively, for the blend sign and 2.75 [1.64–4.67] and 2.62 [1.60–4.30], respectively, for the island sign). Hypodensities demonstrated low PPVs of 0.41 (110/269) or lower for IVHG when stratified by OIT. When OIT was ≤ 2 h, the PPVs of hypodensities, blend sign, and island sign for RHE were 0.80 (215/269), 0.90 (142/157), and 0.83 (103/124), respectively. Conclusion Hypodensities, blend sign, and island sign were the best NCCT predictors of RHE when OIT was ≤ 2 h. NCCT signs may assist in earlier recognition of the risk of hemorrhagic growth and guide early intervention to prevent neurological deterioration resulting from hemorrhagic growth.

Objective:To find the preferences of nursing staff when they provide " Internet + nursing service" for elderly patients.Methods:By means of the discrete choice experiment, a questionnaire was designed to investigate the preferences of nursing staff when they provide " Internet + nursing services" for elderly patients. In-service nursing staff from 8 medical and health institutions in Ningbo city and Wenzhou city were selected by random sampling, for an online questionnaire survey conducted from May to June 2022. The preferences of nursing staff on their service income, service content, service distance, service continuity and residence status of elderly patients when providing " Internet + nursing service" were analyzed by mixed logit regression.Results:A total of 420 valid questionnaires were collected. Compared to 50 yuan/order, nursing staff preferred to a price of 150 yuan/order ( β= 1.22, P<0.001) nursing services; Compared to specialized nursing services, nursing staff preferred to the routine care ( β= 0.86, P<0.001) and health promotion ( β= 0.86, P<0.05) service; Compared to<5 km, nursing staff were unwilling to provide nursing services for elderly patients at distances of 5-10 km and 11-15 km ( β=-0.66, P<0.05; β=-0.95, P<0.001) ; Compared to 1-2 visits per month, nursing staff preferred not to provide continuing care services ( β=-0.70, P<0.05); Compared to homestay with the patient family, nursing staff preferred to provide nursing services for elderly patients residing in nursing homes ( β= 1.21, P<0.001) . Conclusions:Considering the preference of nursing staff tend to provide " Internet + nursing service" for the elderly patients with services featuring appropriate price, non-specialist care, close distance, low continuity (moderate intensity used as the reference) and security assurance for practice.

Objective:To investigate the current situation of the " Internet plus nursing services" for the elderly in Ningbo, and evaluate the promotion effect of the pilot policy, for reference to further optimize such service policy of China nationwide.Methods:The data came from the orders for " Internet plus nursing services" by elderly users over 60 years on the " cloud hospital" platform in Ningbo from 2016 to 2021. Descriptive analysis was used to study major demographic information, types of service items and number of person-times of the elderly users; The promotion effect of the pilot policy on " Internet plus nursing services" for the elderly in 2019 was analysed by Chow test.Results:The number of elderly users increased from 76 person-times in 2016 to 5 923 person-times in 2021, accumulating up to 12 209 person-times. The number of nursing service items increased from 18 in 2016 to 36 in 2021. The person-times of users of common clinical nursing and specialized nursing service items were 11 850 and 359 respectively. After the pilot policy was issued, the number of service items and the number of users were significantly increased in 2020( P<0.05). Conclusions:The development of " Internet plus nursing services" for the elderly in Ningbo had achieved certain results, especially with the promotion of the pilot policy in 2019, the types of service items and the number of elderly users had increased year by year. In the future, we should continue to focus on the elderly living alone and other special elderly groups with the support of relevant policies, further expand the scale of elderly users, improve the types of service items, and optimize the charging standards to help China′s healthy aging process.

Objective To compare the dose difference of intensity-modulated radiotherapy (IMRT) with different gantry angle between target volumes and surrounding normal tissues in lumbar spinal metastases therapy. Methods Ten patients with lumbar spinal metastases were enrolled in the study. Three plans with the same prescription dose of 3000 cGy/10f were designed by seven-equal beams (plan-A), five-back beams (plan-B) and seven-back beams (plan-C). All the plans were designed with the same objective function and dose limiting condition. The difference of dosimetric parameters of planning target volume (PTV), organ at risk (OAR), normal tissues, and treatment parameters in all the plans were compared with SPSS 21.0 statistical software. Results All the plans satisfied the clinical requirement. There was no significant difference in the D_mean, D_2%, D_98%, CI and HI of PTV between plan-A and plan-C (P >0.05), and these parameters of plan-A and plan-C were better than plan-B (P < 0.05). Compared with the other two plans, plan-B reduced the dosimetric parameters of bilateral kidney (P < 0.05), whereas plan-B increased the D_max of spinal cord (P < 0.05). The V₅ and V₁₀ of normal tissue of plan-B were lower than the other two plans while the V₁₅, V₂₀ and V₂₅ showed inverse relationship (P < 0.05). plan-B had certain advantages in shortening the monitor units and treatment time (P < 0.05).. Conclusions The seven-equal beams (plan-A) and seven-back beams (plan-C) IMRT plans can provide better target dose distribution, and reduce the D_max of spinal cord. Five-back beams (plan-B) IMRT plan had certain advantages in protecting bilateral kidney and shortening treatment time.

Objective:To investigate the antiviral efficacy of direct-acting antiviral agents (DAAs) in the treatment of liver transplantation (LT) recipients with hepatitis C virus (HCV) infection.Methods:Twenty-two HCV-infected LT recipients treated with DAAs at Fifth Medical Center of Chinese PLA General Hospital from December 2014 to June 2018 were retrospectively analyzed, Twenty cases of HCV RNA gene type 1b were treated with sofosbuvir (400 mg/d) + ledipasvir (90 mg/d) or sofosbuvir (400 mg/d) + daclatasvir (60 mg/d) for 12 weeks or 24 weeks; 2 cases of gene type 2a were treated with sofosbuvir (400 mg/d) for 12 weeks. The effect of antiviral treatment, adverse reactions during treatment, and laboratory indicators such as HCVRNA quantification, blood routine, liver and kidney function during treatment and follow-up were studied.Results:The LT recipients of HCV infection included 16 males and 6 females, with a median age of 61.5 (36-71) years old, and the median time of antiviral treatment was 48 (2-117) months after transplantation. Among the 22 patients, 16 received a 12-week course of treatment. Except for 2 patients who did not get HCVRNA negative conversion at 4-week, all achieved a negative HCV RNA at 4-week and the end of the treatment. Six LT recipients received a 24-week course of treatment (gene type 1b), and HCVRNA was negative at 4-week and the end of treatment. All patients achieved end of treatment virological response and a sustained virological response (SVR) rate of 100% at 12 weeks and 24 weeks after the end of treatment. The serum levels of alanine aminotransferase (ALT) and creatinine were 71.5 (30, 110) U/L and (89.4±25.7) mmol/L before treatment, respectively. ALT decreased to 22 (17.8, 28.5) U/L after 4 weeks of treatment, and serum creatinine decreased to (77.4±11.5) mmol/L at 24 weeks after the end of treatment. The differences before and after treatment were statistically significant (all P<0.05). No serious adverse events occurred during the treatment. Conclusions:DAAs have a definite antiviral effect in the treatment of LT recipients with HCV infection, and long-term SVR can be obtained.
