ObjectiveTo explore the coercive experience of involuntarily hospitalized adolescents with mental disorders during the admission process and hospitalization， providing references for formulating targeted nursing interventions. MethodsSemi-structured interviews were conducted with 15 involuntarily hospitalized adolescents with mental disorders selected from October to December 2023， and the themes were summarized and extracted by content analysis. ResultsA total of 3 themes and 10 sub-themes were extracted， which were used to elaborate the essential contents， causes， and improvement methods of coercive experience. These encompassed the multi-dimensional content of coercive experience （complex emotional experience， different physical sensations， and contradictory cognitive evaluation）， the multi-faceted causes of coercive experience （insufficient personal preparation， inadequate parental communication， and strict medical management system）， as well as the phased improvement of coercive experience （adequate communication before hospitalization， patient notification before coercive intervention， respecting for demands during coercive intervention， and comforting explanation after coercive intervention）. ConclusionThe essential content of the coercive experience of involuntarily hospitalized adolescents with mental disorders is complex and has various causes， which require cooperation from multiple parties to improve. Therefore， parents should respect the expression of their children’s self-will， and medical staff should respect patients’ autonomy， establishing a protection-constrained doctor-patient relationship model and collaborating to reduce the use of coercive interventions， to improve the overall medical satisfaction of adolescents with mental disorders.

BackgroundVestibular neuritis is a common clinical acute peripheral vertigo disorder. Some patients may experience negative emotions states， leading to chronic exacerbation of vestibular neuritis and a poorer prognosis. Further research is needed to understand the psychological state of patients with vestibular neuritis and its influencing factors. ObjectiveTo explore the relationship between depressive symptoms and vestibular symptoms in patients with vestibular neuritis and its influencing factors， so as to provide references for clinical intervention. MethodsA total of 86 patients with vestibular neuritis， hospitalized in the Department of Neurology of the Third Hospital of Mianyang from June 2021 to June 2023， were included in the study. Assessments were conducted using the Hamilton Depression Scale-17 item （HAMD-17）， Dizziness Assessment Rating Scale （DARS） and Dizziness Handicap Inventory （DHI）. Patients were divided into depression group（n=46） and non-depression group（n=40） based on HAMD-17 score. Pearson correlation analysis was used to examine the correlation among each scale score. Binary Logistic regression was used to identify influencing factors for depressive symptoms. ResultsAmong the 86 patients， 46 （53.49%） exhibited depressive symptoms. Statistically significant differences were observed between depression group and non-depression group in terms of age， disease duration， years of education， DARS score and DHI score （t=4.512， 4.921， 2.712， 3.529， 5.471， P<0.01 ）. In depression group， HAMD-17 score was positively correlated with DARS score and DHI score （r=0.345， 0.335， P<0.01）. Binary Logistic regression analysis showed that age （OR=4.352， 95% CI： 1.520~12.462）， disease duration（OR=3.772， 95% CI： 1.339~10.630）， years of education （OR=0.074， 95% CI： 0.235~0.923）， DARS score （OR=1.213， 95% CI： 0.405~3.628） and DHI score （OR=3.619， 95% CI： 1.246~10.514） were the influencing factors of depressive symptoms among patients with vestibular neuritis. ConclusionDepressive symptoms in patients with vestibular neuritis are positively correlated with vestibular symptoms. Risk factors for depressive symptoms in patients with vestibular neuritis include age， disease duration， DARS score and DHI score， while years of education serve as a protective factor.

Objective     To investigate the effect and prognosis of patients with ventricular septal rupture after myocardial infarction treated by surgical repair combining an occluder and a patch. Methods     Clinical data of 42 patients with myocardial infarction complicated with ventricular septal rupture admitted to the First Affiliated Hospital of Zhengzhou University from January 2010 to September 2021 were retrospectively analyzed. According to the surgical methods, 27 patients were divided into a traditional group, including 17 males and 10 females, with an average age of 62.81±6.81 years, who were repaired by patch only, and 15 patients were divided into a modified group, including 11 males and 4 females, with an average age of 64.27±9.24 years, who were repaired by surgery combining an occluder and a patch. Perioperative and follow-up data of the two groups were compared and analyzed. Results     There were statistical differences between the two groups in preoperative Killip grading, rate of intra-aortic balloon pump use, interval from myocardial infarction to operation, and the number of culprit artery (P<0.05). There was no statistical difference in other preoperative data, the cardiopulmonary bypass time, aortic cross-clamping time, postoperative hospital stay or in-hospital death rate between the two groups (P>0.05). No residual shunt occurred in the modified group, and the difference was statistically significant compared with the traditional group (P=0.038). There was no statistical difference in other complications between the two groups (P>0.05). The median follow-up time was 4 years. Two patients in the traditional group and one in the modified group died during follow-up. The follow-up cardiac function grading of patients in the modified group was statistically different from that in the traditional group (P=0.023). Conclusion     The perioperative  mortality of ventricular septal rupture after myocardial infarction is high, but the long-term effect is satisfactory. Surgical repair combining an occluder and a patch is a safe and effective treatment for ventricular septal rupture, which can effectively reduce postoperative residual shunt.

ObjectiveTo investigate the effect and mechanism of Yiyi Fuzi Baijiangsan （YYFZBJ） on the apoptosis of colon cancer cell line HCT116. MethodYYFZBJ at different concentrations （0.5， 1， 2， 4， 6， 8， 10， 12， 14， 16 g·L^-1） was used to intervene in HCT116 cells for 24， 48， 72 h. The cell counting kit-8 （CCK-8） method was used to determine the effect of YYFZBJ on cell proliferation in vitro. The cells were divided into a blank group， a capecitabine group（1.8 g·L^-1）， and low-， medium-， and high-dose YYFZBJ groups （6， 10， and 14 g·L^-1） and treated for 48 hours. Flow cytometry was used to detect the apoptosis. Hoechst 33342 staining was used to observe the apoptotic morphology of cells. Mitochondrial membrane potential （MMP） was analyzed by a mitochondrial-targeted deep-red fluorescent probe （Mito-Tracker Red CMXRos）. The expression of proteins related to the mitochondrial apoptosis pathway， such as B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cytochrome C （Cyt C）， cysteinyl aspartate-specific protease （Caspase）-9， Caspase-3， cleaved Caspase-9， and cleaved Caspase-3 was detected by Western blot. The mRNA levels of Bcl-2， Bax， Cyt C， Caspase-9， and Caspase-3 were determined by real-time polymerase chain reaction （Real-time PCR）. ResultCompared with the blank group， YYFZBJ （8， 10， 12， 14， 16 g·L^-1） significantly inhibited the proliferation of HCT116 cells in vitro （P<0.05） in a dose-dependent manner. Compared with the blank group， the medium- and high-dose YYFZBJ groups and the capecitabine group showed increased apoptosis rates of colon cancer cells （P<0.05）. The YYFZBJ groups and the capecitabine group showed reduced number of colon cancer cells with significantly changed cellular morphology and cell apoptosis manifestations， such as strong dark blue fluorescence， nucleus concentration， shrinkage， and fragmentation. With the increase in the mass concentration of YYFZBJ， the blue fluorescence intensity was significantly enhanced. Compared with the blank group， the YYFZBJ groups and the capecitabine group showed reduced MMP in a dose-dependent manner， decreased protein and mRNA levels of Bcl-2， and increased protein expression of Bax， Cyt C， Caspase-9， Caspase-3， cleaved Caspase-9， and cleaved Caspase-3 and mRNA expression of Bax， Cyt C， Caspase-9， and Caspase-3 （P<0.05）. ConclusionYYFZBJ can induce the apoptosis of colon cancer HCT116 cells through the mitochondrial apoptosis pathway.

ObjectiveTo conduct a systematic review of systematic reviews of the effect of preoperative prerehabilitation training on postoperative function of patients after total knee arthroplasty. MethodsThe systematic reviews and meta-analysis about the application of preoperative prerehabilitation training after total knee arthroplasty were retrieved from Cochrane Library, Embase, PubMed, Web of Science, Wanfang Data, CNKI and VIP database, from establishment to March 10th, 2023. The methodological quality was evaluated using AMSTAR. The meta-analysis of the reseaches without repetitive content was performed using RevMan 5.3. ResultsA total of ten systematic reviews/meta analyses were included. Compared with the routine rehabilitation, preoperative prerehabilitation training might decrease the scores of Western Ontario and McMaster Universities Osteoarthritis Index (MD = -1.34, 95%CI -1.94 to -0.74, P < 0.001), and Hospital for Special Surgery Knee Score (MD = -1.04, 95%CI -1.69 to -0.40, P = 0.001), shorten the length of hospital stay (MD = -1.01, 95%CI -1.66 to -0.36, P = 0.002), and enhance muscle strength three months after operation (SMD = 0.63, 95%CI 0.30 to 0.97, P < 0.001). ConclusionPreoperative prerehabilitation training can improve postoperative knee function, enhance muscle strength three months after operation, and shorten length of hospital stay for the patients after total knee arthroplasty.

Objective:To investigate the clinical application of carbon nanoparticles mapping lymph nodes in curative resection for colorectal carcinoma.Methods:Patients diagnosed with colorectal cancer before operation and undergoing radical surgery with intact postoperative pathological data in the Sixth Affiliated Hospital, Sun Yat-sen University from March 2016 to March 2018 were included in this retrospective case-control study. Those who were diagnosed with ileus, recurrent carcinoma or underwent emergency operation were excluded. A total of 1421 cases were included, with 156 cases in the carbon nanoparticles mapping group and 1265 cases in the control group. Using 1∶3 case control matching based on gender, weight, TNM staging and neoadjuvant chemotherapy, 145 and 435 cases were finally recruited in the carbon nanoparticles mapping group and control group, respectively. Patients in the carbon nanoparticles mapping group underwent preoperative colonoscopy with carbon nanoparticles submucosal injection 2.4 (1.0 - 14.0) days before operation. Carbon nanoparticles of 0.25 ml was injected at 4 points (3, 6, 9 and 12 o'clock each) 0.5-1.0 cm around the tumor. The number of eliminated lymph node, number of positive lymph node and positive rate between the two groups were compared, and the number of eliminated lymph node in different subgroups of T stage, N stage, TNM stage and neoadjuvant chemotherapy was analyzed and compared.Results:After case control matching, total number of eliminated lymph nodes in the carbon nanoparticles mapping group was significantly higher than that in the control group (22.2±11.2 vs. 19.0±9.5, t=3.025, P=0.003). However, no statistically significant differences were found in the number of positive lymph node and lymph node positive rate between two groups (all P>0.05). Subgroup analysis showed that as compared to the control group, total number of eliminated lymph nodes in the carbon nanoparticles mapping group was significantly higher in T3 stage subgroup (median: 22 vs. 18, Z=2.435, P=0.015), N0 stage subgroup (median: 20.5 vs. 17.5, Z=2.772, P=0.006), TNM II stage subgroup (median: 23.5 vs. 19.0, Z=2.654, P=0.008) and neoadjuvant chemotherapy (median: 22.5 vs. 13.0, Z=3.287, P=0.001), while compared to the control group, the number of positive lymph node (median: 4.0 vs. 6.5, Z=-2.530, P=0.011) and the lymph node metastasis degree (median: 16% vs. 31%, Z=-2.862, P=0.004) were lower in the carbon nanoparticles mapping group in N2 subgroup. Conclusion:Carbon nanoparticles mapping lymph nodes can effectively enhance the number of eliminated lymph nodes in curative resection for colorectal cancer.
