Immunotherapy has been widely used in cancer treatment in recent years and functions by stimulating the immune system to kill tumor cells. Radiation therapy (RT) uses radiation to induce DNA damage and kill tumor cells. However, this activates the body's immune system, promoting the release of tumor-related antigens from inactive dendritic cells, which stimulates the recurrence and metastasis of tumors in immune system tissues. The combination of RT and immunotherapy has been increasingly evaluated in recent years, with studies confirming the synergistic effect of the two antitumor therapies. Particularly, the combination of RT by dose adjustment with different immunotherapies has positive implications on antitumor immunity as well as disease prognosis compared with respective monotherapies. This review summarizes the current research status, progress, and prospects of RT combined with immunotherapy in cancer treatment. It additionally discusses the prevalent concerns regarding the dose, time window, and toxicity of this combination therapy.

OBJECTIVES: To investigate the changes in blood levels of calcium and bone metabolism biochemical markers in patients with primary osteoporosis receiving treatment with denosumab. METHODS: Seventy-three patients with primary osteoporosis treated in our Department between December, 2021 and December 2023 were enrolled. All the patients were treated with calcium supplements, vitamin D and calcitriol in addition to regular denosumab treatment every 6 months. Blood calcium, parathyroid hormone (PTH), osteocalcin (OC), type I procollagen amino-terminal propeptide (PINP), and type I collagen carboxy-terminal telopeptide β special sequence (β‑CTX) data before and at 3, 6, 9, and 12 months after the first treatment were collected from each patient. RESULTS: Three months after the first denosumab treatment, the bone turnover markers (BTMs) OC, PINP, and β-CTX were significantly decreased compared to their baseline levels by 39.5% (P<0.001), 56.2% (P<0.001), and 81.8% (P<0.001), respectively. At 6, 9, and 12 months of treatment, OC, PINP, and β-CTX remained significantly lower than their baseline levels (P<0.001). Blood calcium level was decreased (P<0.05) and PTH level increased (P<0.05) significantly in these patients at months of denosumab treatment, but their levels were comparable to the baseline levels at 6, 9, and 12 months of the treatment (P>0.05). CONCLUSIONS Denosumab can suppress BTMs and has a good therapeutic effect in patients with primary osteoporosis, but reduction of blood calcium and elevation of PTH levels can occur during the first 3 months in spite of calcium supplementation. Blood calcium and PTH levels can recover the baseline levels as the treatment extended, suggesting the importance of monitoring blood calcium and PTH levels during denosumab treatment.

To summarize the perioperative nursing experience of a patient with thoracic and abdominal aortic dissection aneurysm after Stanford type A aortic dissection surgery,who underwent intra-abdominal aortic aneurysm endovascular isolation,in situ fenestration branch covered stent placement,and artificial blood vessel bypass.The nursing points include regular evaluation of the intra-abdominal pressure of the patient,being on guard against the rupture of the dissection;specialist nurses participated in the preoperative multidisciplinary discussion;establishing an emergency plan for the rescue of ruptured aortic dissection;monitoring the vital signs of patients closely to prevent critical complications during surgery.After multidisciplinary treatment and meticulous care,the patient's surgery went smoothly and the postoperative recovery was good.The patient was discharged 8 days later.

Objective:To compare postural stability and balance in different tasks between people with and without chronic, non-specific low back pain (CNLBP).Methods:Twenty patients with CNLBP formed the study′s CNLBP group, while 25 healthy counterparts were chosen as a normal group. Both groups were tested for their ability to standing on one leg with their eyes closed (the SOLEC test), for postural balance, for postural stability (PST), and had their limits of stability (LOS) time determined. The results were compared.Results:Compared to the normal group, the CNLBP group showed a significant difference in left-right weight-bearing in a bipedal semi-squat and in two-legged alternate standing. Shifting the center of gravity in bipedal standing revealed significant differences in LOS time, anterior-posterior stability index (APSI), mediolateral stability index (MLSI) and overall stability. In bipedal standing with the eyes closed there were significant differences in APSI, MLSI and OSI observed. On average, the CNLBP group had significantly shorter SOLEC and LOS times on the left and rear left sides.Conclusions:The CNLBP patients had some postural control deficits compared to their healthy counterparts and were less able to maintain static balance on their left leg and dynamic balance. They were less able to maintain postural balance in a bipedal semi-squat and during alternate leg standing. They are at greater risk of falling when moving the body′s center of gravity to the left or the rear left side.

Objective:To investigate the application effect of web-based problem-based learning (WPBL) versus traditional teaching in the teaching of geriatric medicine courses.Methods:PubMed, Embase, the Cochrane Library, Web of Science, CNKI, CBMdisc, and Wanfang Data were searched for clinical studies on the application of WPBL in the teaching of geriatric medicine courses in China and globally published up to October 1, 2023. After literature screening, data extraction, and quality assessment, RevMan5.4.1 was used to perform a systematic review.Results:A total of 14 eligible articles were included in this study, with 1 436 medical students as the subjects and geriatric medicine as the content of teaching. The Meta-analysis showed that WPBL teaching had a better effect than traditional problem-based learning or lecture-based learning in the teaching of geriatric medicine courses and could improve the theoretical examination score [mean difference (MD)=3.53, 95% confidence interval (CI)=1.77-5.29, P<0.001], operational skills (MD=5.92, 95%CI=2.67-9.18, P<0.001), critical thinking ability (MD=9.30, 95%CI=5.43-13.18, P<0.001), and teaching satisfaction (MD=1.75, 95%CI=1.49-2.01, P<0.001) among medical students. Conclusions:WPBL in the teaching of geriatric medicine courses can improve the theoretical examination score, operational skills, critical thinking skills, and teaching satisfaction among medical students.

Objective:To explore surgical strategies for acute type A aortic dissection involving severe stenosis or occlusion of the carotid arteries.Methods:From January 2019 to March 2023, a total of 29 patients with acute type A aortic dissection involving severe stenosis or occlusion of the carotid arteries were included in the study. All patients underwent emergency surgery, with simultaneous intraoperative neck incision and replacement of the unilateral or bilateral carotid arteries. Among them, there were 19 males with a mean age of(49.57±2.14)years old. Preoperative brain CT indicated abnormalities in 15 cases, transient neurological dysfunction occurred in 5 cases, and syncope in 1 case.Results:Procedures included ascending aorta replacement in 10 cases, Bentall procedure in 18 cases, and Wheat procedure in 1 case. Arch operations involved partial arch replacement in 3 cases and Sun’s procedure in 26 cases. Simple left carotid artery replacement was performed in 6 cases, simple right carotid artery replacement in 19 cases, and bilateral carotid artery replacement in 4 cases. Cerebral protection measures during circulatory arrest included unilateral cerebral perfusion in 24 cases and bilateral cerebral perfusion in 5 cases. The mean operation time was(7. 6±0. 3) h, with a mean cardiopulmonary bypass time of(196. 3±8. 7) min, aortic cross-clamp time of(113.2±6.4) min, ischemic time 12(5-16.5) min, and lowest temperature of(26.3±0.4)°C. One patient experienced in-hospital mortality. Postoperatively, new neurological dysfunction occurred in 2 cases, including 1 case with coma and permanent neurological deficit.Conclusion:In patients with acute type A aortic dissection involving severe stenosis or occlusion of the carotid arteries, simultaneous carotid artery replacement via neck incision during aortic surgery is a safe and reliable surgical approach.

Objective:To investigate the application value of a multi-dimensional digital moni-toring platform for perioperative period in gastric cancer patients.Methods:The retrospective cohort study was conducted. The clinical data of 50 patients who underwent laparoscopic radical gastrec-tomy in The Affiliated Hospital of Nanjing University of Chinese Medicine from July 2022 to January 2024 were collected. There were 35 males and 15 females, aged (64±12)years. All patients followed the concept of enhanced recovery after surgery, and the multi-dimensional digital monitoring platform based on wearable monitoring equipment was used to implement perioperative management measures. Observation indicators: (1) results of heart rate variability (HRV) monitoring; (2) results of blood glucose and blood oxygen monitoring; (3) results of exercise and sleep monitoring; (4) results of body composition monitoring. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(IQR). Repeated measurement data were analyzed using the repeated ANOVA. Measurement data with skewed distri-bution were transformed to normal distribution by SPSS transformation function before testing. For comparison between pre- and postoperation, paired sample t test was used for measurement data with normal distribution, and nonparametric Wilcoxon signed rank sum test was used for measure-ment data with skewed distribution. Results:(1) Results of HRV monitoring. From preoperation to the third day after surgery, the standard deviation normal to normal heart beat of 50 patients was changed from(103±26)ms to(101±36)ms, the mean of the standard deviations of normal to normal heart beat calculated per 5 min segment was changed from (45±16)ms to(33±12)ms, the number of pairs of adjacent NN intervals differing by more than 50 ms in the entire recording was changed from 6.02%(4.96%) to 5.79%(4.20%), the low frequency power was changed from 376.78(468.96)ms 2 to 742.79(525.20)ms 2, the high frequency power was changed from 273.61(273.58)ms 2 to 397.48(164.87)ms 2, the ratio of low frequency power to high frequency power was changed from 1.6±0.5 to 1.6±0.6, showing significant differences in above indicators before and after operation ( F=34.43, 26.15, 24.58, 5.51, 6.11, 6.02, P<0.05). (2) Results of blood glucose and blood oxygen monitoring. From preoperation to the third day after surgery, the blood glucose of 50 patients was changed from 6.75(2.05)mmol/L to 6.90(2.63)mmol/L, showng a significant difference before and after operation ( F=45.84, P<0.05). The blood oxygen was changed from 97.00%(5.00%) to 97.50%(3.00%), showing no significant difference before and after operation ( F=2.25, P>0.05). (3) Results of exercise and sleep monitoring. From preoperation to the third day after surgery, the number of steps fo 50 pati-ents was changed from 3 043(1 224) to 1 473(767), sleep duration was changed from(8.2±1.1)hours to(7.3±0.8)hours, sleep score was changed from 80±10 to 78±5,showing significant differences in above indicators before and after operation ( F=716.46, 29.02, 47.32, P<0.05).(4) Results of body composition monitoring. The body weight of 50 patients was changed from (63±8)kg to(61±8)kg before and after operation, body fat rate was changed from 24%±8% to 22%±9%, muscle mass was changed from 43 (12)kg to 41(17)kg, body mass index was changed from (23.0±2.6)kg/m 2 to(22.1±2.5)kg/m 2, showing significant differences in above indicators before and after operation ( t=8.19, 3.00, Z=-2.78, t=7.34, P<0.05), while there was no significant difference in basal metabolic indicators from (1 390±134)kcal to (1 379±139)kcal before and after operation ( t=1.02, P>0.05). Conclusion:The multi-dimensional digital monitoring platform for preoperative period can accurately monitor the perioperative stress level and evaluate the postoperative recovery of gastric cancer patients, which can present the visual results.
