ABSTRACT

ABSTRACT The treatment of soft tissue injury in football players generally includes physical therapy, anti-inflammatory and analgesic drug treatment, surgical treatment and early rest immobilization. Western medicine treatment of soft tissue injury can quickly heal the wound and relieve pain in a short time. The treatment of traditional Chinese medicine is based on the whole and must seek the root of the disease. It is believed that the occurrence of certain diseases is related to Qi, blood, liver and kidney deficiency, so we should pay attention to the overall adjustment during treatment of symptoms. In view of this, this study analyzed the effect of Chen Yuan ointment, from traditional Chinese medicine, in the treatment of soft tissue injury. Sixty-eight football players who completed ankle ligament reconstruction were divided into four groups according to the type of operation and whether Chen Yuangao-assisted rehabilitation was used or not. The results showed that the Ankle Hindfoot Function Score and the visual analog scale (VAS) score of patients in the fibula brevis tendon reconstruction Chen Yuan ointment group were 98.3 and 0.3, respectively, at the last follow-up, which were better than those in other groups, and had lower pain scores. This result shows that Chen Yuangao has a certain effect in the treatment of soft tissue injury, which can provide a research idea for the rapid rehabilitation of football players.


RESUMO O tratamento de lesões dos tecidos moles em jogadores de futebol inclui geralmente terapia física, tratamento anti-inflamatório e analgésico, tratamento cirúrgico e imobilização de repouso precoce. O tratamento de lesões nos tecidos moles, utilizando a medicina ocidental, pode curar rapidamente as lesões e aliviar a dor em pouco tempo. A medicina tradicional chinesa se baseia no todo e deve procurar a raiz da doença. Acredita-se que a ocorrência de certas doenças está relacionada à deficiência de Qi, sangue, fígado e rim do corpo humano, por isso devemos prestar atenção ao ajuste global no tratamento dos sintomas. A partir desta perspectiva, este estudo analisou o efeito da tradicional pomada chinesa Chen Yuan no tratamento de lesões dos tecidos moles. No total, 68 jogadores de futebol que fizeram reconstrução dos ligamentos do tornozelo foram divididos em quatro grupos de acordo com o tipo de operação e se a pomada Chen Yuangao ajudou ou não na reabilitação. Os resultados mostraram que o escore da função do tornozelo retropé (Ankle Hindfoot Function Score) e o escore da Escala Analógica Visual (EVA) dos pacientes do grupo pomada Chenyuan para reconstrução do tendão fibular curto foram 98,3 e 0,3, respectivamente, no último seguimento, sendo melhores do que os de outros grupos e apresentando menores níveis de dor. Estes resultados mostra que a pomada Chen Yuangao exerce certo efeito no tratamento de lesões dos tecidos moles, pode constituir uma ideia de pesquisa para a rápida reabilitação dos jogadores de futebol.

ABSTRACT

ABSTRACT The current football can effectively exercise the body of college students and improve their physical health. How to use modern intelligent technology to perform quantitative research on the influencing factors of football on college students' physical health is the current development trend. Based on this, this paper studies the influencing factors of college students' physical health under the intervention of football. First of all, this paper puts forward an analysis model of college students' physical health based on the sarsa algorithm. The autocorrelation function is used to simulate and process the students' physical information. Through the maximum value of the autocorrelation function curve in the detection process, the detection signal is restored, then the error of the sarsa algorithm is analyzed. Secondly, this paper expounds the influence factors of sarsa algorithm on students' physical health in football. Fuzzy evaluation method and analytic hierarchy process are used in the evaluation. Aiming at the shortcomings of AHP, the improved sarsa algorithm is used for comprehensive analysis, and an adaptive simulation evaluation system is established. Finally, the effectiveness of the sarsa algorithm in this system is verified by many football experiments.

ABSTRACT

It has been reported that ODB genes play an important role in homologous recombination-directed DNA repair, suggesting their potential applications in plant breeding. To analyze the expression characteristics of tobacco NtODB gene, the cDNA sequence of NtODB was obtained using in silico cloning technique. The physicochemical properties, signal peptide, and advanced structures of the predicted protein were analyzed using bioinformatics tools. The results showed that the NtODB gene has a 579-bp open reading frame which encodes a protein with 192 amino acid residues. The protein NtODB is predicted to be alkaline and hydrophilic. Real-time quantitative PCR showed that NtODB was constitutively expressed in different tissues. Subcellular localization showed that NtODB was mainly expressed in cell membrane and chloroplast. These results may help us to better understand and elucidate the roles of ODB genes in the homologous recombination-directed DNA repair.

ABSTRACT

Objective:To investigate the effects of methyltransferase-like protein 14 (METTL14)-mediated long-chain non-coding RNA EIF3J antisense RNA1 (Inc EIF3J-AS1) on the migration and invasion of cholangiocarcinoma cells and its mechanism.Methods:From September 2017 to December 2018, 10 pairs of cholangiocarcinoma and adjacent normal tissues were collected from the First Affiliated Hospital of Naval Medical University, which were surgically resected and pathologically confirmed. The expression of METTL14 mRNA and Inc EIF3J-AS1 in cholangiocarcinoma tissues was detected by fluorescence quantitative PCR, and the protein expression of METTL14 was detected by Western blotting. Cholangiocarcinoma cell lines HUCCTI and RBE were divided into control group and METTL14 or Inc EIF3J-AS1 knockdown group. The corresponding normal lentivirus was transfected in the control group, and METTL14 or Inc EIF3J-AS1 knockdown group was transfected with lentivirus that interfered with the expression of METTL14 or Inc EIF3J-AS1, respectively. Transwell assay was used to detect the ability of cell migration and invasion, and Western blotting was used to detect the expression of epidermal growth factor receptor (EGFR) and AKT protein.Results:The expressions of METTL14 mRNA and lnc EIF3J-AS1 in cholangiocarcinoma tissues were significantly higher than those in adjacent normal tissues (0.075±0.012 vs 0.031±0.006, 0.140±0.032 vs 0.064±0.012), and there was a positive correlation between expression of METTL4 mRNA and expression of lnc EIF3J-AS1 ( r=0.883, P=0.0007). The expression of METTL14 protein in cholangiocarcinoma tissues was higher than that in adjacent normal tissues (0.354±0.131 vs 0.187±0.183). Compared with the control group, the expression of lnc EIF3J-AS1 was significantly lower in METTL14 or Inc EIF3J-AS1 knockdown group (0.217±0.020 vs 1.000±0.052, 0.149±0.066 vs 1.000±0.045). The migration and invasion ability of cell lines HUCCTI and RBE decreased significantly in lnc EIF3J-AS1 knockout group (5.00±0.58 vs 23.33±0.33, 20.33±0.67 vs 70.67±0.33; 12.00±0.58 vs 25.00±2.52, 22.33±0.89 vs 43.67±0.33). The expression of EGFR and p-AKT/AKT protein were also significantly decreased (0.109±0.015 vs 1.000±0.018, 0.226±0.036 vs 1.000±0.051; 0.118±0.052 vs 1.000±0.069, 0.132±0.098 vs 1.000±0.023). The above differences were statistically significant (all P<0.05). Conclusions:Abnormal expression of lnc EIF3J-AS1 in cholangiocarcinoma mediated by METTL14 can promote tumor cell migration and invasion.

ABSTRACT

Objective:To analyze the clinical and pathological features and gene mutations of pancreatic acinar cell carcinoma (PACC).Methods:Clinical data of 34 patients with PACC admitted to the Department of Pancreatic Surgery of the First Affiliated Hospital of Naval Medical University from December 2009 to July 2018 were retrospectively analyzed to summarize its clinical characteristics, and the expressions of α1-ACT, CaM5.2, Syn and CgA in pancreatic tumor tissues were detected by immunohistochemistry. Next-generation gene sequencing technology was used to detect gene mutations in tumor specimens.Results:Among the 34 PACC patients, 23(68%) were males and 11(32%) were females; the age ranged from 25 to 75 years, with an average age of 54 years. The first symptom was abdominal pain or distension in 21 cases (62%), skin or scleral yellow staining in 4 cases(12%), and 9 cases(26%) were found in routine physical examination. BMI was 17.6-34.0 kg/m 2, of which 3 cases (9%) were <18.5 kg/m 2, 23 cases (68%) were 18.5-24.0 kg/m 2, and 8 cases (23%) were >24.0 kg/m 2. Preoperative examination showed elevated CA19-9 in 7 cases (20.6%), elevated CEA in 3 cases (8.8%), and elevated AFP in 7 cases (20.6%). Blood amylase was 16-247 U/L, with an average of 80 U/L. Enhanced CT showed that the lesion was irregular in shape, showing inhomogeneity and slightly low density, with areas of cystic degeneration and necrosis. The tumor was located in the head of the pancreas in 14 cases (41%), the body and tail of the pancreas in 19 cases (56%), and the neck of the pancreas in 1 case (3%). The largest tumor diameter was 1.5-15.5 cm, with an average of 5.4 cm. Postoperative pathologic stage I was confirmed in 4 cases (12%), stage Ⅱ in 14 cases (41%), stage Ⅲ in 14 cases (41%) and stage Ⅳ in 2 cases (6%). Immunohistochemical results showed that both α1-ACT and CaM5.2 were positively expressed (100%). Syn was positive in 8 cases (23.5%) and CgA was positive in 6 cases (17.6%). Ki-67 index was from 9% to 70%, with an average of 41%. Gene sequencing of pancreatic tumor tissue from 6 patients showed BRCA2 mutation in 2 patients (7155C>G), K-ras mutation in 1 patient (35G>T), RET mutation in 1 patient (200G>A), and LKB1 mutation (234G>T) in 1 patient, and one double mutation of K-ras and RET (35G>A, 1 798C>T). 30 patients were followed up, and the median survival was 38.3 months. Conclusions:PACC was a rare pancreatic tumor with no specific clinical manifestations. The positive expression rates of α1-ACT and CAM5.2 in tumor tissues were 100%. BRCA2, K-ras, RET and LKB1 were common gene mutations.

ABSTRACT

With the increasing incidence of pancreatic ductal adenocarcinoma (PDAC) in patients, it is estimated to be the second leading cause of cancer-related mortality in China. Despite the survival rate of PDAC patients is still poor. PDAC is characterized by the high complexity of stomal tissue, which includes immune cells, various growth factors, extracellular matrix and fibroblasts. TME accounts for about 15%-85% of the whole tumor component in PDAC. Emerging evidences have suggested that TME might play important roles in the tumor progress and drug-resistance of chemotherapy and a plenty of promising TME-related target molecules have been under early clinical trials. Nevertheless, there still lacks effective therapeutic treatments for improving the overall survival of PDAC patients. At present, progress has been made in the research of targeted therapies combined with matrix depletion, drug delivery and immunoregulation in PDACs. Thus, this review will focus on the latest progress in the fields of TME components including immune cells, growth factors, extracellular matrix and fibroblasts, as well as the therapeutic targets produced by these TME components.

ABSTRACT

Objective:To investigate the risk factors for delayed gastric emptying (DGE) following pancreaticoduodenectomy (PD).Methods:Clinical data of 385 patients who underwent PD in Changhai Hospital of Navy Medical University from January 2017 to November 2017 were retrospectively analyzed, including 235 men and 150 women. According to the definition of DGE by the International Study Group of Pancreatic Surgery (ISGPS), patients were divided into-clinically irrelevant DGE (non CR-DGE) group and clinically relevant DGE(CR-DGE) group. Univariate analysis and multivariate logistic analysis were used to identify the risk factors of CR-DGE after PD.Results:Of the 385 patients, 78 cases (20.3%) developed DGE. There were 35 cases of CR-DGE (9.1%). In the multivariate analysis, BMI( OR=1.117, 95% CI1.006-1.240, P=0.038), preoperative serum albumin( OR=0.902, 95% CI 0.832-0.977, P=0.012), the main pancreatic duct diameter (MPD)≤3 mm( OR=2.397, 95% CI 1.016-5.653, P=0.046), soft texture of pancreas( OR=2.834, 95% CI 1.093-7.350, P=0.032), clinically relevant postoperative pancreatic fistula (CR-POPF)( OR=4.498, 95% CI 1.768-11.441, P=0.002) were independent risk factors for CR-DGE after PD. Conclusions:High BMI, low preoperative serum albumin, MPD ≤3 mm, soft texture of pancreas and CR-POPF after surgery were independent risk factors for CR-DGE, and early clinical interventions should be performed.

ABSTRACT

Objective:To investigate the expression of tripartite motif 14 (TRIM14) in human pancreatic cancer and analyze its relationship with clinicopathological features and prognosis, and further explore its functional mechanism in the development and progression of pancreatic cancer.Methods:176 pairs of pancreatic cancer tissues and corresponding adjacent tissues resected by surgery in Changhai Hospital affiliated with Navy Medical University from January 2016 to December 2018 were collected. The protein expression of TRIM14 in pancreatic cancer and adjacent normal tissue was detected by immunohistochemical staining. TRIM14 and phosphorylated p65 expression in pancreatic cancer was measured by western blotting. NF-κB targeting gene Bcl-xl, CCND1, VEGF-C mRNA was tested by real time quantitative PCR. The correlation between TRIM14 expression and clinicopathological characteristics was analyzed. The relationship between TRIM14 expression and tumor-free survival and overall survival of pancreatic cancer patients was evaluated by univariate and multivariate Cox regression model. The internal relationship between TRIM14 expression and the activation of NF-κB signaling pathway was analyzed.Results:The positive TRIM14 expression rate in pancreatic cancer was obviously higher than that in adjacent normal tissue [86.93%(153/176) vs 27.27%(48/176)], and the difference was statistically significant ( P<0.05). The expression level of TRIM14 was correlated with the clinical stage, lymph node metastasis and invasion depth of pancreatic cancer ( P=0.000, 0.000, 0.021), but not obviously with gender, age, differentiation degree and distant metastasis. Cox regression analysis showed that the expression level of TRIM14 was the independent risk factor for tumor-free survival ( RR=1.706, 95% CI 1.237-2.429, P=0.029) and overall survival ( RR=1.806, 95% CI 1.984-2.831, P=0.029). The expression level of TRIM14 was tightly associated with the phosphorylation level of p65 ( R=0.86, P<0.01), and the mRNA expression of Bcl-xl, CCND1 and VEGF-C was highly correlated with TRIM14 expression ( R=0.85-0.92, P<0.01). Conclusions:TRIM14 was highly expressed in pancreatic cancer tissues and was an independent risk factor for prognosis of pancreatic cancer patients. TRIM14 participates in the development and malignant progression of pancreatic cancer potentially via activating NF-κB pathway.

ABSTRACT

Pancreatic cancer is the most lethal malignancy with an overall 5-year survival rate less than 9%, mainly due to late diagnosis and lack of effective therapeutic options.In the last decade, post-operative survival has been enhanced with advent of neoadjuvant therapy and combined adjuvant therapy.Furthermore, the information gained from the omics data, including next generation sequencing data, hasn′t yet begun to affect treatment of pancreatic cancer patients.However, in terms of precision medicine, pancreatic cancer has always lagged behind other tumors.Therefore, combined with practical experience, summary of the latest development and research progress of precise medical treatment of pancreatic cancer, especially from the fields of molecular biology and experimental models, is of critical importance. Further development of precise medicine for pancreatic cancer based on platforms using PDX and organoid model would promisingly help in effective improvement of clinical treatment.

ABSTRACT

OBJECTIVE: To investigate the application and clinical value of total pancreatectomy that combined vascular reconstruction with en bloc resection through both left and right pathways in pancreatic neck tumor. METHODS: The clinical data concerned about 12 patients of pancreatic neck tumor accepted total pancreatectomy combined vascular reconstruction with en bloc resection through both left and right pathways in Changhai Hospital,Naval Military Medical University between March 2015 and March 2017 were analyzed retrospectively. The clinical data especially the data in general situation,operation,hospital stay,perioperative complications,postoperative pathology,condition of surgical margin,postoperative survival time and prognosis were analyzed. RESULTS: All of the 12 patients were diagnosed with pancreatic neck tumor infringing the peripancreatic arteriovenous vein and had accepted total pancreatectomy joint with intravenous resection and reconstruction. The median age of patients was 58 years,whose median BMI reached 23.41,and the number of males was up to 6,equal as females. The information about the operation was as follows:no intraoperative death case,median surgery time being 235 min,median intraoperative blood loss being 800 m L,median plasma-reduced blood transfusion volume being 600 mL,median resection length of vessel being 4.10 cm,median time of portal vein blocking being 15 min. After the operation,9 cases were conducted to large tissue biopsy examination with R0 resection rate of 91.7%. Besides,all the patients were managed with ERAS technique with the postoperative pain relief rate of 100%. Only one case suffered from gastric emptying disorder(Grade A)and two cases had infection. No patients died 30 days after operation,whose median postoperative hospital stay was 12 days and median survival time was 19.8 months. CONCLUSION: The total pancreatectomy combined vascular reconstruction with en bloc resection through both left and right pathways is safe and efficient to treat pancreatic neck tumor,improving operation security and living quality of patients. However,the surgery is so difficult that it could only be applied in certain pancreatic surgery centers with high levels.

ABSTRACT

In recent years,with the progress of imaging and diagnostic technology,the detection rate of pancreatic neuroendocrine neoplasms has increased rapidly.However,its clinical manifestations are diverse,the rate of misdiagnosis is high,the therapeutic treatments are complex,and the guidelines for diagnosis and treatment are relatively imperfect,which has caused great trouble in clinical practice.Especially in surgical treatment,it is difficult to choose between preservation of pancreatic function and standard radical resection,especially for tumors less than 2 cm.At the same time,whether lymph node resection should be performed is another open question.Because it is difficult to carry out randomized controlled studies,most of the studies on this issue are long-span retrospective studies based on public databases,which are greatly influenced by factors such as time,medical level in different regions and different surgeons.It is the confounding factors that lead to inconsistent results.

ABSTRACT

Because of the high malignancy of pancreatic ductal adenocarcinoma, the cancer-related mortality of pancreatic ductal adenocarcinoma is increasing year by year. Despite advance in surgical techniques, the 5-year survival rate of patients after resection is still less than 30%. Recent studies have found that pancreatic ductal adenocarcinoma is a systemic disease, which may not be cured completely by up-front resection, but requires perioperative multidisciplinary therapy. With the concept of "potentially curable pancreatic cancer" , clinicians need to evaluate the resectability of pancreatic ductal adenocarcinoma accurately before operation, and use the innovative multidisciplinary therapy including neoadjuvant chemoradiotherapy,surgery and adjuvant chemoradiotherapy to improve the R0 resection rate and reduce the risk of early metastasis. Therefore, the therapeutic goal of pancreatic ductal adenocarcinoma is no longer "simple resection" , but long survival through perioperative multidisciplinary treatment. In this article, we briefly introduce the progress of resectability assessment, surgical techniques and perioperative adjuvant therapy of "potentially curable pancreatic cancer" .

ABSTRACT

Objective:To observe the effect of football, badminton and table tennis on kinetic visual acuity for children in grade one to three at elementary schools. Methods:From February to June, 2019, A total of 123 children aged seven to nine years from four elementary schools were divided into control group (n = 32), badminton group (n = 33), table tennis group (n = 30) and football group (n = 28). The children in the experimental groups accepted ball playing training for 16 weeks, while the control group did not attended any training course. The kinetic visual acuity was measured before and after training. Results:The kinetic visual acuity improved after training in the experimental groups (t > 2.196, P < 0.05), but not in the control group (t = 1.570, P > 0.05). The rates of improvement of kinetic visual acuity were: football (26.82%), badminton (25.44%) and table tennis (19.21%). Conclusion:The ball games play a positive role in improving kinetic visual acuity for children in junior grades, especially the big ball games.

ABSTRACT

Pancreatic cancer is a common malignancy with the worst prognosis.Radical surgery has been the only curative treatment for pancreatic cancer.With the advancement of surgical techniques and the implementation of the concept of comprehensive treatment for cancer in recent years,neoadjuvant therapy for pancreatic cancer has received more attention.There are continuing controversies in the hotspots and difficulties,with opportunities and challenges coexisting.Four famous experts and their teams in pancreatic surgery discussed selection strategy of neoadjuvant therapy for pancreatic cancer based on clinical experiences.Professor Wang Chunyou proposed that surgery was prior for patients with a higher likelihood of achieving R0 resection for pancreatic cancer to avoid the possibility of tumor progression and loss the opportanity of radical resection during neoadjuvant therapy.For patients with less chance of radical resection for pancreatic cancer and unresectable pancreatic cancer,neoadjuvant therapy is worthy of a positive attempt.Professor Jin Gang and his team believed that neoadjuvant therapy played an important role in improving the survival time of patients with pancreatic head cancer,especially with borderline resectable pancreatic head cancer.After neoadjuvant therapy,pancreatic surgeons should pay attention to improvement of surgery safety and R0 resection rate.Professor Dai Menghua and his team suggested that patients with resectable pancreatic cancer and borderline resectable pancreatic cancer could benefit from neoadjuvant therapy,which required proof from clinical trials.Surgeons should choose the appropriate treatment strategy based on guidelines and individual conditions for patients with pancreatic cancer.Professor Shao Cheghao and his team suggested that surgical treatment after neoadjuvant therapy or translational therapy for locally advanced pancreatic head cancer is safe,effective and feasible,especially for pancreaticoduodenectomy with combined revascularization.For the treatment of patients with pancreatic head cancer after neoadjuvant chemotherapy,the choice of next treatment options,evaluation indicators,timing of surgery and surgical methods need to be further studied.

ABSTRACT

Objective To detect miR-34a expression in pancreatic cancer tissue and BxPC3 cells,determine the target genes and analyze the correlation of the expression of miR-34a and its target genes with clinicopathological parameters in pancreatic cancer as well as the influence on the proliferation and migration abilities of BxPC3 cells.Methods c-MET 3'UTR dual-luciferase reporter vectors cloned wild-type and mutant c-MET 3'UTR to validate that c-MET was the target gene of miR-34a,respectively.Liposome was used to establish miR-34a overexpressing BxPC3 cells (miR-34a group) and c-MET downregulating BxPC3 cells (c-METsi group).qPCR,Western blot and IHC was used to measure the mRNA and protein expression of miR-34a and c-MET.The cell viability and migration ability of miR-34a overexpressing BxPC3 cells was assessed by CCK-8 and transwell assay.Results In miR-34a group,the 3'UTR of wild-type c-MET was obviously downregulated compared with that of control group [(65.00 ± 4.04) % vs 100%,P =0.00131)],but no statistical difference was found between two mutant groups,which proved that c MET was the target gene of miR-34a.The expression level of miR-34a was significantly down-regulated in cancer tissues compared to adjacent normal tissues by an average fold change of 1.92,and the difference was statistically significant (P =0.003).Compared with control group,c-MET mRNA and protein expression was obviously decreased in miR-34a group (0.045 ±0.003 vs 0.085 ±0.001,0.400±0.058 vs 1.133 ±0.120).After 4-day culture,the cell viability of miR-34a group and c-METsi group was obviously decreased (P =0.0012;P =0.0001),the transmembrane cells was also obviously decreased(231 ± 12 vs 351 ± 16,P =0.0039;259 ±7 vs 351 ± 16,P=0.0066),and the differences were statistically significant.miR-34a overexpression and c-MET positively expression in pancreatic cancer were significantly associated with TNM stage and tumor differentiation (P <0.001),and the expression of c-MET negatively correlated with miR-34a (P <0.001).Conclusions miR-34a was lowly expressed in pancreatic cancer,and its tumor suppressive activity may be partly through inhibiting c-MET.Overexpressing miR-34a or inhibiting c-MET may be new targets for the diagnosis and treatment of pancreatic cancer.
