Mechanism of nitidine chloride inducing apoptosis of cervical cancer cells by inhibiting p53 ubiquitination degradation / 中国药理学通报

Aim To investigate the effect of nitidine chloride (NC) on the apoptosis of cervical cancer cells and its mechanism. Methods Cervical cancer cell lines HeLa and SiHa were selected as subjects. The cytotoxicity of NC and its inhibitory effect on cell growth were detected by CCK-8 assay and clone formation assay. The effect of NC on the apoptosis of cervical cancer cells was detected by TUNEL assay, and the expression of apoptosis-related proteins was detected by Western blot. The effects of NC on the interaction between p53 and E6AP protein, the level of p53 ubiquitination modification and the stability of p53 protein in cervical cancer cells were analyzed by immunoprecipi-tation assay, ubiquitination assay and Western blot assay. Results NC could significantly inhibit the proliferation and induce apoptosis of cervical cancer cells. NC could inhibit the interaction between tumor suppressor protein p53 and E6AP in cervical cancer cells, reduce the level of p53 ubiquitination modification, delay the degradation of p53 and increase the expression level of p53 protein. Conclusions NC can inhibit the ubiquitination and degradation of p53, improve the expression level of p53 protein, restore its tumor suppressor function, and thus play an anti -cervical cancer role.

Clinical features of children with coronavirus disease 2019 caused by Delta variant infection in different age groups / 中国当代儿科杂志

OBJECTIVES@#To study the clinical features of children with coronavirus disease 2019 (COVID-19) caused by Delta variant infection in different ages groups.@*METHODS@#A total of 45 children with COVID-19 caused by Delta variant infection who were hospitalized in the designated hospital in Henan Province, China, from November 17 to December 17, 2021, were included. They were divided into three groups: <6 years group (n=16), 6-13 years group (n=16), and >13 years group (n=13). The three groups were compared in clinical features and laboratory examination data.@*RESULTS@#COVID-19 in all age groups was mainly mild. Main manifestations included cough and expectoration in the three groups, and fever was only observed in the 6-13 years group. The <6 years group had significantly higher serum levels of aspartate aminotransferase, lactate dehydrogenase, and creatine kinase isoenzymes than the other two groups (P<0.05). The 6-13 years group had the highest proportion of children with elevated serum creatinine levels (50%). Among the three groups, only 4 children in the >13 years group had an increase in serum C-reactive protein levels. The 6-13 years group had the lowest counts of CD3+CD4+ lymphocytes, CD3+CD8+ lymphocytes, and natural killer cells in the peripheral blood among the three groups. The >13 years group had a significantly higher positive rate of SARS-CoV-2 IgG on admission than the other two groups (P<0.05). There was no significant difference in the imaging findings on chest CT among the three groups (P>0.05).@*CONCLUSIONS@#The clinical features of COVID-19 caused by Delta variant infection in children of different age groups may be different: children aged <6 years tend to develop myocardial injury, and those aged 6-13 years have fever except cough and expectoration and tend to develop renal and immune dysfunction.

Pediatric myofibroma/myofibromatosis of the soft tissue and bone: a clinicopathological analysis of 28 cases / 中华病理学杂志

Objective: To investigate the clinicopathological features, diagnosis and differential diagnosis of pediatric myofibroma/myofibromatosis of the soft tissue and bone. Methods: All cases of pediatric myofibroma/myofibromatosis of the soft tissue and bone diagnosed between January 2011 and December 2018 were retrieved from the surgical pathology records in the Department of Pathology, Beijing Jishuitan Hospital, Beijing, China. Clinical and radiological data were collected. H&E and immunohistochemistry were used to examine histological and immunophenotypic features and to make the diagnosis and differential diagnosis. The relevant literature was also reviewed. Results: Twenty-eight cases of pediatric myofibroma/myofibromatosis of the soft tissue and bone were respectively collected. The patients' ages ranged from 2 months to 14 years, with a mean age of 7 years. There were 7 females and 21 males. There were 12 cases located in soft tissue, including the finger (n=9), upper arm (n=1) and foot (n=2). There were 14 cases located in the bone of limb, including the femur (n=8), tibia (n=4), clavicle (n=2), fibula (n=2) and radius (n=1). There were 2 cases of myofibromatosis involving multiple bones. Radiology showed lytic lesions in the bone. The proliferation of spindle-shaped myofibroblasts arranged in fascicles with indistinct eosinophilic cytoplasm and bland nuclei, with no pleomorphism and cytological atypia. The characteristic histologic structure was the biphasic nodular growth pattern with cellular and paucicellular regions. The tumors might arrange in a hemangiopericytoma-like pattern. The stroma varied between dense fibrosis and myxoid changes. The reactive new bone formation and inflammatory cell infiltration also existed. Immunohistochemical study showed that the SMA was positive. The surgical resections were performed. One of the patients had tumor recurrence as a result of 11-month follow-up. Conclusions: The pediatric myofibroma/myofibromatosis of the soft tissue and bone is a very rare benign tumor and has a good prognosis. It has a characteristic morphology and its differential diagnosis from other spindle cell tumors could be made with the immunohistochemical analysis.

Junctional adhesion molecule-like protein as a novel target for kaempferol to ameliorate lung adenocarcinoma / 中西医结合学报

OBJECTIVE@#Although there have been improvements in targeted therapy and immunotherapy, the majority of lung adenocarcinoma (LUAD) patients still lack effective therapies. Consequently, it is urgent to screen for new diagnosis biomarkers and pharmacological targets. Junctional adhesion molecule-like protein (JAML) was considered to be an oncogenic protein and may be a novel therapeutic target in LUAD. Kaempferol is a natural flavonoid that exhibits antitumor activities in LUAD. However, the effect of kaempferol on JAML is still unknown.@*METHODS@#Small interfering RNA was used to knockdown JAML expression. The cell viability was determined using the cell counting kit-8 assay. The proliferation of LUAD cells was evaluated using the 5-ethynyl-2'-deoxyuridine incorporation assay. The migration and invasion of LUAD cells were evaluated by transwell assays. Molecular mechanisms were explored by Western blotting.@*RESULTS@#JAML knockdown suppressed proliferation, migration and invasion of LUAD cells, and JAML deficiency restrained epithelial-mesenchymal transition (EMT) via inactivating the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway. Using a PI3K activator (740Y-P), rescue experiments showed that phenotypes to JAML knockdown in LUAD cells were dependent on the PI3K/AKT/mTOR pathway. Kaempferol also inhibited proliferation, migration and invasion of A549 and H1299 cells and partially suppressed EMT through the PI3K/AKT/mTOR pathway. Knockdown of JAML ameliorated the inhibitory effect of kaempferol on LUAD cells. Kaempferol exerted anticancer effects by targeting JAML.@*CONCLUSION@#JAML is a novel target for kaempferol against LUAD cells. Please cite this article as: Wu Q, Wang YB, Che XW, Wang H, Wang W. Junctional adhesion molecule-like protein as a novel target for kaempferol to ameliorate lung adenocarcinoma. J Integr Med. 2023; 21(3): 268-276.

Objective: To elucidate the clinical features of patients with refractory juvenile dermatomyositis (JDM), and to explore the efficacy and safety of tofacitinib in the treatment of refractory JDM. Methods: A total of 75 JDM patients admitted to the Department of Rheumatology and Immunology in Shenzhen Children's Hospital from January 2012 to January 2021 were retrospectively analyzed, and to analyze the clinical manifestations, efficacy and safety of tofacitinib in the treatment of refractory JDM. Patients were divided into refractory group with using of glucocorticoids in combination with two or more anti-rheumatic drugs for treatment, and the presence of disease activity or steroid dependence after a one-year follow-up. The non-refractory group is defined as clinical symptoms disappeared, laboratory indicators were normal, and clinical remission was achieved after initial treatment, and the clinical manifestations and laboratory indexes of the two groups were compared. The Mann-Whitney U test, Fisher's precision probability test was used for intergroup comparison. Binary Logistic multivariate regression analysis was used to identify risk factors for refractory JDM. Results: Among the 75 children with JDM, 41 were males and 34 were females with a age of onset of 5.3 (2.3, 7.8) years. The refractory group consisted of 27 cases with a age of onset of 4.4 (1.5, 6.8) years, while the non-refractory group consisted of 48 cases with a age of onset of 5.9 (2.5, 8.0) years. Compared with 48 cases in the non-refractory group, the proportion of interstitial lesions and calcinosis in the refractory group was higher than that in the non-refractory group (6 cases (22%) vs. 2 cases (4%), 8 cases (30%) vs. 4 cases (8%), both P<0.05). Binary Logistic regression analysis showed that observation group were more likely to be associated with to interstitial lung disease (OR=6.57, 95%CI 1.22-35.31, P=0.028) and calcinosis (OR=4.63, 95%CI 1.24-17.25, P=0.022). Among the 27 patients in the refractory group, 22 cases were treated with tofacitinib, after treatment with tofacitinib, 15 of 19 cases (86%) children with rashes showed improvement, and 6 cases (27%) with myositis evaluation table score less than 48 score both were improved, 3 of 6 cases (27%) had calcinosis were relieved, and 2 cases (9%) had glucocorticoid-dependence children were successfully weaned off. During the tofacitinib treatment, there was no increase in recurrent infection, blood lipids, liver enzymes, and creatinine were all normal in the 22 cases. Conclusions: Children with JDM with calcinosis and interstitial lung disease are more likely to develop refractory JDM. Tofacitinib is safe and effective for refractory JDM.

Diagnosis and treatment status of perioperative anemia in patients with gastrointestinal neoplasms: a multi-center study in Hubei Province / 中华外科杂志

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ2 test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

Organized Hematoma of the Maxillary Sinus: Surgical Excision by Midfacial Degloving Approach

Organized hematoma of maxillary sinus is a rare pathologically benign mass in which pressure in the hematoma increases as it undergoes a process of organization, causing the deformation of the surrounding tissue, mimicking malignancies. The midfacial degloving approach can be used when extensive exposure is required in the treatment of lesions or traumas in the midfacial area with intranasal and intraoral incisions. We report a surgical excision case of organized hematoma of maxillary sinus using midfacial degloving approach without major complications and recurrence after one-year follow up.

Analysis of influencing factors of metabolic syndrome in male occupational population in mineral industry / 中国职业医学

OBJECTIVE: To study the prevalence and influencing factors of metabolic syndrome(MS) in male occupational population in the mineral industry. METHODS: A total of 2 654 male employees in the mining area of a mining group in Xingtai City were selected as the study subjects using the convenient sampling method. The general demographic data, behavior and lifestyle, work status, and biochemical examination results of the study subjects were collected, and the influencing factors of MS were analyzed by multi-factor logistic regression. RESULTS: The detection rate of MS was 16.0%(425/2 654) in these 2 654 male workers. The detection rate of MS increased with age and length of service(all P<0.05). The detection rate of MS in male workers with hypertension, high blood sugar, central obesity, high triglyceride and low high-density lipoprotein was higher than that in control workers(all P<0.01). The results of multivariate logistic regression analysis showed that age, work shifts, salt intake, dietary habit, alcohol drinking, sleep time, physical exercise, and body mass index were all influencing factors for MS(all P<0.05). CONCLUSION: Male workers have a high incidence of MS. Older age, shift work, high-salt diet, meat-based diet, alcohol drinking, severely insufficient sleep time, and overweight/obesity increase the risk of MS in male workers.

Objective To investigate the prevalence and changing trend of Enterobius vermicularis infections among children in Shandong Province, so as to provide the scientific evidence for the adjustment and development of the enterobiasis control strategy. Methods Soil-borne nematodiasis surveillance sites were assigned in 51 counties (districts, cities) in Shandong Province from 2016 to 2020, and the E. vermicularis infections were detected using a modified Kato-Katz technique and the cellophane tape method among children at ages of 3 to 9 years living in these surveillance sites. The epidemiological profiles of E. vermicularis-infected children were descriptively analyzed. Results A total of 5 060 children at ages of 3 to 9 years were detected in 51 soil-borne nematodiasis surveillance sites in Shandong Province from 2016 to 2020, and the overall prevalence of E. vermicularis infections was 2.23%. The annual prevalence of E. vermicularis infections was 3.99% (26/651), 1.70% (14/824), 0.96% (8/837), 2.90% (45/1 552) and 1.67% (20/1 196) from 2016 to 2020, respectively, with a significant difference detected among years ( χ2 = 21.455, P < 0.01). The prevalence of E. vermicularis infections was 1.25% (15/1 198), 1.85% (14/755), 3.18% (84/2 640) and 0 (0/467) among children from central, eastern, southern and northern Shandong Province (χ2 = 27.326, P < 0.01). In addition, there was no significant difference in the prevalence of E. vermicularis infections between male (1.98%, 56/2 831) and female children (2.56%, 57/2 229) (χ2 = 1.916, P > 0.05); however, there was age-specific prevalence of E. vermicularis infections among children (χ2 = 16.448, P < 0.05), with the greatest prevalence detected among children at ages of 6 years (3.18%, 25/786), and the lowest prevalence seen among children at ages of 3 years (0.75%, 6/800). Conclusions The prevalence of E. vermicularis infections remained at a medium level among children at ages of 3 to 9 years in Shandong Province from 2016 to 2020, with region-specific prevalence found across the province. An integrated strategy is required for enterobiasis control.

Salivary Pepsin as an Intrinsic Marker for Diagnosis of Sub-types of Gastroesophageal Reflux Disease and Gastroesophageal Reflux Disease-related Disorders

Background/Aims@#To determine the value of salivary pepsin in discriminating sub-types of gastroesophageal reflux disease (GERD) and GERD-related disorders. @*Methods@#Overall, 322 patients with different sub-types of GERD and 45 healthy controls (HC) were studied. All patients took Gastroesophageal Reflux Disease Questionnaire (GerdQ) and underwent endoscopy and 24-hour esophageal pH monitoring and manometry. Salivary pepsin concentration (SPC) was detected by using colloidal gold double-antibody immunological sandwich assay. Oral esomeprazole treatment was administrated in the patients with non-erosive reflux disease (NERD) and extra-esophageal symptoms (EES). @*Results@#Compared to HC, patients with erosive esophagitis, NERD, EES, EES plus typical GERD symptoms, or Barrett’s esophagus had a higher prevalence of saliva and SPC (all P < 0.001). There was no significant difference in the positive rate for pepsin in patients with functional heartburn or GERD with anxiety and depression, compared to HC. After esomeprazole treatment, the positive rate and SPC were significantly reduced in NERD (both P < 0.001) and in EES (P = 0.001 and P = 0.002, respectively). Of the 64 NERD patients, 71.9% (n = 46) were positive for salivary pepsin, which was significantly higher than the rate (43.8%, n = 28) of pathological acid reflux as detected by 24-hour esophageal pH monitoring (P = 0.002). @*Conclusions@#Salivary pepsin has an important significance for the diagnosis of GERD and GERD-related disorders. Salivary pepsin and 24-hour esophageal pH monitoring may complement with each other to improve the diagnostic efficiency.

Comparable effects of Jiedu Granule, a compound Chinese herbal medicine, and sorafenib for advanced hepatocellular carcinoma: A prospective multicenter cohort study / 中西医结合学报

OBJECTIVE@#Sorafenib has been extensively used for the treatment of advanced hepatocellular carcinoma (HCC), and Chinese herbal medicine has also been used to manage advanced HCC. The present work evaluates the effectiveness and safety of Jiedu (JD) Granule, a compound of traditional Chinese herbal medicine, side-by-side with sorafenib for the treatment of advance HCC.@*METHODS@#Patients with advanced HCC receiving treatment with JD Granule or sorafenib were enrolled from December 2014 to March 2018. The primary endpoint was overall survival (OS). The secondary endpoints were progression-free survival (PFS) and safety. Propensity score matching (PSM) analysis was used to control for possible selection bias from the study group allocation process.@*RESULTS@#Of the 325 patients included, 161 received JD Granule and 164 received sorafenib. No significant differences were found in OS or PFS among patients receiving JD Granule compared to sorafenib (P > 0.05). Median OS of the two study groups was 6.83 months (95% confidence interval [CI]: 5.83-9.47) in the group receiving JD Granule and 8 months (95% CI: 6.67-9.80) in the group receiving sorafenib, with half-, 1- and 2-year survival rates of 53.6%, 31.2% and 13.2% vs 60.1%, 35.5% and 14.2%, respectively. Even after PSM, the median survival time did not differ between the JD Granule group (9.03 months; 95% CI: 6.37-14.2) and the sorafenib group (7.93 months; 95% CI: 6.5-9.97), with comparable half-, 1- and 2-year survival rates. The most common adverse events (AEs) were diarrhea (13.7%) and fatigue (5.6%) in the JD Granule group, and hand-foot skin reaction (46.3%) and diarrhea (36.6%) in the sorafenib group. The JD Granule was more cost-effective than sorafenib treatment for advanced HCC.@*CONCLUSION@#Compared to sorafenib, JD Granule was more cost-effective and caused fewer AEs for the treatment of Chinese patients with advanced HCC.

Cervical lesions caused by HPV subtype infection / 上海预防医学

Objective To investigate the relationship between human papillomavirus (HPV) infection and cervical lesions, and to explore the application value of HPV typing in cervical disease screening. Methods Colposcopic examination and cervical biopsy were performed in 1 851 cases of HPV positive patients from January 2017 to September 2018 in the cervical disease clinic of Shanghai First People's Hospital.Pathological diagnosis was used as the gold standard to analyze the distribution of HPV subtypes and the relationship between HPV subtypes and cervical lesions. Results Among 1 851 patients, high-risk human papillomavirus (HPV) infection was the main type.The detection rate of HPV 16 was the highest, followed by HPV52, HPV58, HPV53 and so on.A total of 234 patients with positive biopsy results were found, and 77 patients with CIN2 or above lesions were detected.The ratio of CIN2 or above patients with HPV 16 was 11.8% (45/380), higher than 2.4% (32/1 328) of other high-risk subtypes such as HPV52 and HPV58.The difference was statistically significant(χ2=61.60, P < 0.001).In the age factor, the high-risk positive ratio of HPV in the 35-year-old group was 96.91% (1 225/1 264), higher than 94.38% (554/587) in the 35-year-old group.The difference was statistically significant (χ2=6.898, P=0.009).The detection rate of CIN1 disease was 12.64% (234/1 851) in HPV classification test, 8.59% (159/1 851) in liquid based thin layer cytology test (TCT), and the detection rate of TCT as a screening method was lower than that of HPV test method (χ2=16.01, P < 0.001). Conclusion The survey find that HPV subtypes are the most common in the order of HPV16, HPV52, HPV58, HPV53 and HPV18.HR-HPV infection was closely related to cervical lesions, and with the increase of high-risk infections, the degree of cervical lesions also increased.The detection rate of HPV typing is higher than that of TCT screening for cervical lesions.HPV genotyping has high sensitive and negative predictive value in screening cervical lesions.

Results Among 1 851 patients, high-risk human papillomavirus (HPV) infection was the main type.The detection rate of HPV 16 was the highest, followed by HPV52, HPV58, HPV53 and so on.A total of 234 patients with positive biopsy results were found, and 77 patients with CIN2 or above lesions were detected.The ratio of CIN2 or above patients with HPV 16 was 11.8% (45/380), higher than 2.4% (32/1 328) of other high-risk subtypes such as HPV52 and HPV58.The difference was statistically significant(χ2=61.60, P < 0.001).In the age factor, the high-risk positive ratio of HPV in the 35-year-old group was 96.91% (1 225/1 264), higher than 94.38% (554/587) in the 35-year-old group.The difference was statistically significant (χ2=6.898, P=0.009).The detection rate of CIN1 disease was 12.64% (234/1 851) in HPV classification test, 8.59% (159/1 851) in liquid based thin layer cytology test (TCT), and the detection rate of TCT as a screening method was lower than that of HPV test method (χ2=16.01, P < 0.001). Conclusion The survey find that HPV subtypes are the most common in the order of HPV16, HPV52, HPV58, HPV53 and HPV18.HR-HPV infection was closely related to cervical lesions, and with the increase of high-risk infections, the degree of cervical lesions also increased.The detection rate of HPV typing is higher than that of TCT screening for cervical lesions.HPV genotyping has high sensitive and negative predictive value in screening cervical lesions.

Hematoma Expansion within 24 hours of Hypertensive Intracerebral Hemorrhage and Its Association with Signs on Nonenhanced Computed Tomography / 中国医学科学院学报

To explore the correlation between hematoma expansion within 24 hours of hypertensive intracerebral hemorrhage and signs on nonenhanced computed tomography(NECT). Methods The clinical data and CT images of 185 patients with hypertensive intracerebral hemorrhage were retrospectively analyzed.The differences in CT parameters were compared between the expansion group and the unexpanded group.Binary logistic regression analysis was performed on the indicators with statistical significance between the two groups to identify the potential correlation between CT parameters and hematoma expansion.The roles of blend sign,lobulation sign,and black hole sign in predicting early hematoma expansion were assessed. Results The CT quantitative data including initial volume,maximum diameter,minimum diameter,maximum CT value,mean CT value,difference between maximum diameter and minimum diameter showed no significant difference between these two group(all >0.05).CT qualitative data including blend sign,lobulation sign,and black hole sign were significantly different(<0.05)but the differences became not significant after the hematoma broke into the ventricles.Binary logistic regression analysis showed that blend sign,lobulation sign,and black hole sign were independent risk factors for early hematoma expansion,with sensitivity,specificity,positive predictive value,and negative predictive value of the combined signs and the early hematoma expansion calculated by the four-fold table method being 78.4%,59.0%,42.1%,and 87.8%,respectively,and the Youden index was 0.374.Its Youden index was closer to 1 than the blend sign,the black hole sign,and the lobulation sign. Conclusion The blend sign,lobulation sign,and black hole sign in NECT can be used to predict hematoma expansion within 24 hours after hypertensive cerebral hemorrhage.

Thoughts on establishing subordinate comprehensive training base for submarine rescue of Chinese navy / 第二军医大学学报

On-shore port-based training is important to improve naval submarine rescue and escape capability. It is highly necessary to establish subordinate comprehensive training base for submarine rescue and escape, so as to solve the current problems in on-shore port training. Taking into consideration of the organizational leadership, coordination mechanism, supporting system, operational mode, main function, role design, numbers and location of setting, and supplementary measures, we put forward a general concept for the training base, hoping to provide ideas for innovating the training mechanism and improving the training effectiveness of naval submarine rescue and escape capability.
