Objective:To explore the clinical effect of positive reinforcement theory nursing intervention in the rehabilitation treatment of patients with cervical spondylosis and its influence on cervical function and quality of life.Methods:From March 2017 to May 2020, 94 patients who received rehabilitation after anterior cervical decompression surgery were selected as the research samples. They were divided into the control group and the study group by random digits table method with 47 cases in each group. The control group was given routine nursing care, and the study group received positive reinforcement theoretical nursing intervention on the basis of the control group.The nursing effect,cervical vertebra function and quality of life before and after nursing were evaluated by Visual Analogue Scale(VAS), Japanese Orthopaedic Association assesses treatment(JOA) score, SF-36. The nursing satisfaction rate was evaluated by questionnaire.Results:The JOA score, quality of life score and VAS score of the study group before nursing were (7.57 ± 1.35), (56.78 ± 5.62), (6.53 ± 0.34) respectively, while those of the control group were (7.32 ± 1.27), (56.32 ± 5.31), (6.32 ± 0.31) respectively, and there was no significant difference between the two groups ( P > 0.05). The JOA score and quality of life score of the study group after nursing were (15.73 ± 0.33) and (91.67 ± 2.34) respectively, which were higher than those of the control group (12.18 ± 0.46) and (83.43 ± 3.33) respectively. The VAS score of the study group after nursing was (2.33 ± 0.11) and lower than that of the control group (4.53 ± 0.25). The differences were statistically significant ( t values were 3.47, 5.43, 4.67, P< 0.05). Compared with the control group, the nursing satisfaction rate of the study group was higher than that of the control group (85.11%, 40/47 vs. 97.87%,46/47, χ2 value was 4.92, P < 0.05). Conclusions:Positive reinforcement theory nursing intervention can effectively relieve the pain symptoms of patients, improve the cervical function, and effectively improve the quality of life.

Objective:To study the effect of comprehensive nursing combined with cervical spine health care on postoperative psychological status and the prevention of various complications of patients with cervical spine surgery.Methods:A total of 102 patients who underwent cervical spine surgery in Dalian Third People′s Hospital from June 2018 to February 2020 were selected as the research objects. The patients were randomly divided into a control group and an experimental group. The control group was given routine care, and the experimental group was given comprehensive care combined with cervical spine for health care intervention, the main observation indicators included the mental state of the two groups of patients, the incidence of postoperative complications, and the patients' satisfaction with nursing work.Results:After comprehensive nursing combined with cervical health care intervention, the SAS score of the control group was 50.14±3.51 and the SAS score of the experimental group was 30.27±1.12. The SAS score of the control group was significantly higher than that of the experimentalgroup ( t value was 24.134, P< 0.05); the SDS score of the control group was 50.45±1.11, the SDS score of the experimental group was 39.45±2.21, the SDS score of the control group was significantly higher than that of the experimental group ( t value was 20.293, P<0.05), the difference was statistical significance: Compared with the control group (27.45%,14/51), the incidence of postoperative complications (9.80%,5/51) in the experimental group was significantly reduced ( χ2 value was 10.409, P<0.05); the nursing attitude of the patients to nursing staff (91.11± 5.32), nursing quality (90.41±2.30), nursing responsibility (92.82±4.69) in the experimental group were all significantly higher than those of the control group (80.67±3.51, 80.21±4.43, 80.78±4.82), the difference was statistically significant ( t value was 9.151, 14.671, 16.124, P<0.05). Conclusion:Rehabilitation nursing intervention of comprehensive nursing combined with cervical spine health care can improve mental state, reduce incidence of complication and increase satisfaction degree for patients undergoing cervical spondylopathy surgery, which is worthy of further clinical application and promotion.

Objective To detect the expression of translationally controlled tumor protein (TCTP) in squamous cell carcinoma (SCC) tissue and cell lines A431 and SCL-1,and to evaluate the effect of TCTP on apoptosis in and proliferation of SCC cells.Methods An immunohistochemical method was used to measure the expression of TCTP in tissue specimens from 65 patients with SCC.Western blot was performed to detect the expression of TCTP in A431 and SCL-1 cells.Three small interference RNAs (siRNAs) targeting the TPT1 gene were designed,synthesized,and transfected into A431 cells.Then,reverse transcription (RT)-PCR and Western blot were conducted to measure the expression of TPT1 mRNA and TCTP,respectively,methyl thiazolyl tetrazolium (MTT) assay and flow cytometry were carried out to detect cell proliferation and apoptosis,respectively.Results TCTP was overexpressed in SCC tissue specimens,and the expression level was positively correlated with the histologic grading of SCC (P ＜ 0.05).Western blot showed that TCTP was expressed in both A431 and SCL-1 cells,and the expression was relatively high in A431 cells.The transfection efficiency of siRNAs varied from 90％ to 95％.A decrease in the expression of TPT1 mRNA and TCTP was induced by the siRNAs in A375 cells (all P ＜ 0.05).Conclusion The downregulation of TCTP expression may increase the apoptosis in and suppress the proliferation of A431 cells.

Objective To observe the operation of Nav1.6 voltage-gated sodium channels in rats with acute cerebral injury after electroacupuncture therapy and investigate the mechanism.Methods Male Sprague-Dawley rats were randomly divided into an ischemia control group (IC,n =48),an electroacupuncture group (ET,n =48),a nimodipine therapy group (NT,n =48) and a sham operation group (SO,n =24),and were treated accordingly.A model of acute cerebral ischemia was induced by occlusion of the right middle cerebral artery using the suture method.The expression of Nav1.6,the concentration of Ca2+ and infarct volume were observed at 6 h,1 d,2 d and 3 d after ischemia with the real-time quantitative fluorescence PCR,immunofluorescence and 2,3,5-triphenyl tetrazolium chloride methods,respectively.Results The Joshua score for neural function was zero in the sham operation group,and increased gradually in the three other groups 6 h and1 and 2 d after ischemia.The average Joshua score 3 d after ischemia was significantly lower than 1 d earlier in each group.In the ET group the expression of Nav1.6 was significantly upregulated at first,followed by a significant decrease.The concentration of Ca2+ behaved similarly.However,no significant changes were observed in the infarction volume percentage.At 3 d after ischemia the expression of Nav 1.6,the Joshua grades,the Ca2+ concentrations and the infarction volume percentage were all significantly lower in the ET group compared with the IC,NT and SO groups.Conclusion Electroacupuncture therapy after acute cerebral ischemia can inhibit the expression of Navl.6,reduced Na + inflow and calcium overload,and mitigate acute cerebral ischemic injury,at least in rats.The protective effect may be attributed to inhibiting the expression of Nav 1.6.

Objective More early esophageal cancers are treated by endoscopy.However,whether submucosal patients are suitahle for endoscopic treatment is still controversial,and few domestic researches were conducted in this area.The present study investigated the impact of submucosal invasion depth on lymph node metastasis.Methods A total of 258 patients who underwent esophagectomy from November 2009 to March 2014 were studied.Submucosal invasion was equally categorized into inner one-third(sml),middle one-third(sm2),and deep one-third(sm3) invasion by pathologists.Demographics of patients,tumor characteristics,and surgical information were retrospectively collected through medical records.They were compared according to different submucosal invasions.Cancer characteristics and its association with LNM were analyzed by univariate and multivariate analysis.Results The study included 75 sml (29.1％),73 sm2(28.3％),and 110 sm3(42.6％) patients,and the rates of LNM were 12.0％ (9/75),11.0％ (8/73),20.9％ (23/110),respectively.sm3 might be associated with regional LN M (univariate analysis,P =0.041).Tumor volume ＞ 1.856 cm3 (P =0.022) and lymphovascular invasion (P =0.004) predicted LNM using multivariate analysis.Conclusion Submucosal ESCC showed a substantial rate of LNM and it seems that they are not suitable for endoscopic treatment.Depth of invasion was not an independent risk factor for LNM.

Objective: To evaluate the concordance of PD-L1 expression in various tissues using antibodies 28-8 and SP263 on their respective detection platforms. Methods: Three hundred seventy four specimens of surgical resection of pulmonary diseases in the First Affiliated Hospital of Nanjing Medical University from January 1, 2012 to January 31, 2017 were collected. Totally 374 cases were tested for PD-L1 expression using the two antibodies, 28-8 and SP263, by respective detection platforms (Dako and Ventana). Finally, 336 cases were used for further evaluation, and the results were statistically analyzed for concordance. Results: For non-small cell lung carcinoma (NSCLC), the positive rate of PD-L1 was 57.5% (177/308) using SP263, and 57.5% (177/308) using 28-8 antibody. The correlation coefficient was 0.97 (P<0.01). The positive rate of both benign lung diseases and paracancerous tissues was about 10.7% (3/28), and the positive concordance rate was 100.0%. The distribution of both antibodies was also relatively consistent. Conclusions The expression levels of 28-8 and SP263 antibodies in NSCLC and other tissues are relatively consistent, suggesting both antibodies may be complementary and substitute for each other, which may be useful in guiding clinical management.

Objective:To investigate the clinicopathological characteristics, genetic features, diagnosis and differential diagnosis of pulmonary artery intimal sarcoma (PAIS).Methods:Three cases of PAIS were collected from Jiangsu Province People′s Hospital (from February 2016 to November 2019). The clinical data, imaging examination, morphology, immunostaining, and molecular changes were retrospectively analyzed.Results:There were 1 male and 2 females (age: 32, 50, 60 years), who had symptoms of cough, asthma or chest tightness. Imaging findings indicated low density filling defects which were suspected as thrombus, embolism or myxoma. Grossly, the main tumor was located in the elastic arteries and their lobar branches, also extended into the atrium and ventricle, with lung parenchymal infiltration focally. Microscopically, tumor cells were predominantly composed of abundant spindle cells with obvious atypia and myxoid background, resembling fibroblastic or myofibroblastic differentiation. Active mitotic figures and necrosis could be seen in some areas. Immunohistochemical staining of vimentin was strongly positive, while pan-cytokeratin, S-100, desmin, Fli-1, CD31, SMA and ERG etc were variably positive only in focal areas. FISH detection showed amplification of MDM2 gene in three cases and EGFR gene in two cases. Metastatic lesions were found in one case by 18, 32 and 42 months after surgery respectively. There was no recurrence or metastasis in the other two cases.Conclusions:PAIS is one of exceptionally poor differentiated mesenchymal tumor that arises from the arterial intima of elastic pulmonary arteries. There was no definite differention in morphology. Gene detection shows amplification of MDM2 and EGFR gene. This tumor often has poor prognosis with aggressive behavior. Complete resection is the only effective therapeutic option. There is disagreement as to whether chemotherapy and radiotherapy can improve survival.

Objective:To investigate the clinicopathological features and differential diagnosis of polymorphous low-grade neuroepithelial tumor of the young (PLNTY).Methods:Five cases of PLNTY diagnosed at the First Affiliated Hospital and Affiliated Brain Hospital of Nanjing Medical University, Nanjing, China from 2019 to 2021 were collected. All cases were evaluated using clinical and imaging data, histology, immunohistochemical staining and molecular genetics. The relevant literature was reviewed.Results:There were two male and three female patients, aged 10 to 39 years, with an average age of 25 years. Clinically, the tumors were in the temporal lobe (3 cases), the lateral ventricle (1 case) and the left head of caudate nucleus (1 case). The clinical manifestations included epilepsy in 3 cases, right visual disturbance in 1 case, and post-trauma incidental finding in 1 case. Microscopically, the lesions were characterized with infiltrative growth, cellular pleomorphism (oligodendroglioma-like cells were always present, with low-grade, pleomorphic nuclei) and variable calcifications. Immunohistochemically, the tumor cells were positive for GFAP and Olig2. They also showed intense and diffuse expression of CD34 while CD34 expressing ramified neural elements were present in regional cortex. Ki-67 proliferation index was less than 3%. Molecular genetics showed the BRAF V600E mutation in 2 cases, the PAK5-Q337R missense mutation in 1 case, the FGFR2-CTNNA3 fusion in 1 case, and the FGFR2-INA and FGFR2-PPRC1 concomitant fusion in 1 case. No postoperative chemoradiotherapy was given. Follow-up intervals ranged from 3 to 29 months while no recurrence or metastasis was identified.Conclusions:PLNTY is uncommon. A definite diagnosis of PLNTY relies on histopathological examination and molecular genetics. It is important to distinguish PLNTY from high grade gliomas and avoid overtreatment. The recently reported the PAK5-Q337R missense mutation and the FGFR2-PPRC1 gene fusion in PLNTY may help diagnose and understand the pathogenesis of PLNTY.
