Objective:To study the relationship between endoplasmic reticulum stress (ERS) and apoptotic protein and myocardial pathological changes in rats after endostar combined with low-dose X-ray irradiation.Methods:Forty SD rats were evenly divided into four groups: control group (intraperitoneal injection of equal volume physiological saline, once per day, 14 d), endostar group (intraperitoneal injection of endostar 6 mg/kg, once per day, 14 d), irradiation group (15 Gy divided into 3 times X-ray irradiation) and combination group (intraperitoneal injection of endostar after irradiation at the same dose and time as the endostar group). At 1 and 6 months after treatment, myocardial tissues of rats were prepared for HE staining and Masson staining to observe the myocardial histological changes. TUNEL assay was used to detect myocardial cell apoptosis, and ImageJ software was utilized to calculate myocardial collagen volume fraction (CVF). The expression levels of ERS and apoptotic protein glucose-regulated protein 78 (GRP78), protein kinase-like endoplasmic reticulum kinases (PERK), CCAAT/enhancer binding protein homologous protein (CHOP) and cysteine-containing aspartate-specific protease-12 (Caspase-12) were detected by Western blot. One-way ANOVA was conducted using GraphPad Prism 8.0.1 software, and comparison between two groups was conducted using t-test. Results:At 6 months after treatment, the myocardial interstitium in the irradiation and combination groups was widened, showing strip-like or reticular fibrosis changes, and the myocardial interstitium had diffuse collagen fiber deposition. Compared with the control group, CVF was increased significantly (both P<0.01). At 1 and 6 months after treatment, the apoptotic index of myocardial cells in the combination group was significantly higher than that in the control group ( P<0.05, <0.001). At 1 and 6 months after treatment, the expression levels of GRP78 protein in the irradiation and combination groups were increased (all P<0.01), and the expression levels of PERK and CHOP proteins in the combination group were increased compared to those in the control group (both P<0.05). At 6 months after treatment, the expression levels of PERK and CHOP proteins in the irradiation group were increased compared to those in the control group (both P<0.05). Compared with the control group, Caspase-12 expression levels at 1 and 6 months after treatment were increased in the endostar, irradiation and combination groups (all P<0.05). Conclusions:The expression levels of ERS and apoptotic proteins are related to cardiac injury caused by irradiation in rats. After low-dose X-ray combined with endostar treatment, ERS is aggravated and myocardial apoptosis is increased.

Objective:To explore the potential mechanism of PD-1 inhibitor P on RIMI from the perspective of immune microenvironment.Methods:To establish a mouse model of radiation-induced myocardial injury (RIMI), twenty C57BL/6 mice were randomly divided into 4 groups, 5 in each group. Group A was the healthy control group; Group B was the PD-1 inhibitor group; Group C was the simple irradiation group, with a heart irradiation of 15 Gy; Group D was the irradiation+ PD-1 inhibitor group. One month after irradiation, the mice were anesthetized and sacrificed. The morphological changes of myocardial tissues were observed by HE staining. The myocardial fibrosis was assessed by Masson staining. CD 3+ , CD 3+ CD 4+ , CD 3+ CD 8 lymphocyte subsets and cytokines (IL-4, IL-6, IL-17A, TNF-α, TGF-β 1 and INF-γ) levels were determined by flow cytometry. The apoptosis rate of myocardial cells was detected by TUNE. Results:One month after irradiation, there was no obvious myocardial fibrosis in group B, and collagen fibers were distributed in the interstitium of myocardial cells in groups C and D. Semi-quantitative analysis results showed that the myocardial collagen volume fraction (CVF) of groups A, B, C and D were (1.97±0.36)%, (2.83±1.03)%, (5.39±0.77)% and (7.72±1.43)%, respectively. The CVF between group A and group B was similar ( P=0.314), and the differences in CVF between the other groups were statistically significant (all P<0.05). Compared with group A, the absolute value and percentage of CD 3+ T lymphocytes were significantly increased in groups B, C and D (all P<0.01). The values in group D were significantly higher than those in group B and group C (all P<0.01); The absolute value and percentage of CD 3+ CD4 T lymphocytes were similar among four groups (all P>0.05); The absolute value and percentage of CD 3+ CD 8 T lymphocytes in group D were significantly higher than those in groups A, B and C (all P<0.001). The expression levels of IL-6, IL-17A, and TGF-β 1 in group D were significantly higher compared with those in groups A, B and C (all P<0.001). The apoptotic index was gradually increased in four groups, and the differences in apoptotic index among four groups were statistically significant (all P<0.001). Conclusion:PD-1 inhibitors can aggravate RIMI by promoting myocardial immune inflammatory response.

Objective:To analyze the mediastinal displacement of target volume in the postoperative radiotherapy (PORT) process for non-small cell lung cancer (NSCLC) and the value of mid-term evaluation.Methods:For 100 patients with postoperativeN 2 stage NSCLC, R 1-2 and any N staging, bone anatomy was utilized to measure the change of the first and second CT localization on the same level. Statistical analysis were performed using the WilCoxon, Kruskal-Wallis and χ2 tests. The cut-off values were calculated with the receiver operating characteristic (ROC) curve. Results:Among the included patients, in the PORT process, the mediastinal displacement in the x (front and rear), Y (left and right) and Z (upper and lower) directions were 0.04-0.53 cm, 0.00-0.84 cm and 0.00-1.27 cm, respectively, and the order of mediastinal displacement distance wasz > Y> X,respectively. According to the ROC curve calculation, the cut-off values were 0.263, 0.352 and 0.405, respectively, which were greater than the cut-off values in 25 cases (25%), 30 cases (30%) and 30 cases (30%), respectively. There was significant difference in the three-dimensionalmediastinal displacement ( P=0.007, <0.001 and<0.001). The mediastinal displacement in thex, Y and Z directions had no statistical significance regarding resection site ( P=0.355, 0.239 and 0.256) and operation mode ( P=0.241, 0.110 and 0.064). Comparative analysis of modified whole group mediastinal shift> and cut-off values, medium-simulation (m-S) and the originally planned radiotherapy shown that there was no significant difference in the incidence of radiation esophagitis (RE) and radiation pneumonitis in PORT patients (all P>0.05); however, the incidence of ≥grade 3 RE in the modified plan after m-S was significantly lower than that in the originally planned PORT patients, which were 0 and 7%, respectively ( P<0.001). Conclusions:Mediastinal displacement exists in the PORT process of N 2 or/and R 1-2 cases after radical operation of NSCLC, and obvious movement occurs in 20%-30% of patients. Relocating and modifying the target volume and radiotherapy plan in the middle of the PORT process is beneficial to quality assurance and quality control.

Objective To quantitatively compare the effect of preservation or removal of atlas posterior arch on cervical posterior decompression,so as to provide a basis for reasonable selection of upper cervical spine decompression range and determination of surgical indications for atlas posterior arch resection.Methods The data of 45 patients with posterior decompression of upper cervical spine were retrospectively analyzed.According to the decompression range,the patients were divided into C2-C7 group and C1-C7 group.There were 25 cases in the C2-C7 group,19 males and 6 females,with an average age of 56.3 years (40-71 years),4 cases of cervical spondylotic myelopathy and 21 cases of ossification of the posterior longitudinal ligament of cervical spine.All of the 25 patients underwent open-door laminoplasty:20 cases with hinge side anchoring procedure and 5 cases with preservation of the unilateral posterior muscular-ligament complex procedure (titanium cable procedure).There were 20 cases in C1-C7 group,12 males and 8 females,with an average age of 58A years (44-75 years).All of the 20 cases underwent atlas posterior arch resection as well as C2-C7 open-door laminoplasty,including anchoring procedure in 1 case,titanium miniplate procedure in 4 cases,and titanium cable procedure in 15 cases.Standardized vertebral-cord distance (SVCD) at each level from atlas to level C~ was measured on T2-weighted images of MR on the mid-sagittal plane in the neutral position pedormed 3-12 months postoperatively at each individual level.As the main outcomes,the SVCD values obtained at the same level of the two groups were compared between the two groups.Shapiro-Wilk normality test was performed on the SVCD values at C1.2 and C2 levels of two groups.The area under the normal distribution curve of SVCDs was used to calculate the corresponding residual compression rate with different magnitude of compression mass to further discover the difference of the decompression effect between the two groups.Results The SVCD obtained at the level of the anterior arch of atlas (C1),the junction of odontoid process and axis (C1,2) and the middle part of axis body (C2) in the C2-C7 group was 9.91±1.34 mm,8.35±1.27 mm,and 8.22 ±1.43 mm,respectively.The SVCD at the same levels was 11.02±1.60 mm,9.72±1.24 mm,and 9.12±1.11 mm,respectively.SVCDs differed significantly in the above range between the two groups.However,from level C2,3 to C6,7,there was no significant difference in SVCDs between the two groups.The JOA score of group C2-C7 was 11.8±2.7 preoperatively and increased significantly to 14.7±1.8 at 12 months postoperatively(t=-7.006,P＜0.001) with a recovery rate of 57.0％±32.2％.The JOA score of group C1-C7 was 11.7±2.8 preoperatively and increased significantly to 14.2±2.3 at 12 months postoperatively(t=-6.177,P＜0.001) with a recovery rate of 51.9％±32.1％.Conclusion Atlas posterior arch resection can significantly increase the decompression effect of posterior cervical surgery from the anterior arch of atlas to the middle part of axis body,but it would not increase the decompression effect at level C2.3 or below.When the magnitude of the ventral compression factor exceeds the decompression limit (8.5 mm) available with C2-C7 decompression in the range from atlas to the middle of the axis body,extending the decompression range by atlas posterior arch resection is an effective means to achieve adequate decompression.

Objective To evaluate the clinical efficacy and toxicity of concurrent pemetrexed-cisplatin (PP) or docetaxel-cisplatin (DP) with intensity-modulated radiation therapy (IMRT) in patients with stageⅠV lung adenocarcinoma. Methods Stage IV lung adenocarcinoma patients with unknown EGFR mutation status or wild-type admitted to Guizhou Cancer Hospital from 2011 to 2016 were randomly assigned into the PP (n=50) and DP groups (n=51).All patients received concurrent IMRT of the chest at a prescription dose of 60-70 Gy. Primary endpoint was 1-year survival rate, and secondary endpoint was acute toxicity. Results The overall response rate was 68. 0％ and 72. 5％ in the PP and DP groups (χ2=0. 250, P=0. 617) . The median survival time was 19. 6 months ( 95％CI 13. 9-25. 3) versus 12. 1 months ( 95％CI 10. 7-13. 5) in the PP and DP groups. The 1-, 2-and 3-year overall survival rates were 72. 0％ versus 52. 9％, 28. 0％ versus 17. 6％, and 16. 0％ versus 13. 7％, respectively in the PP and DP groups ( P=0. 049) . In the PP and DP groups, the incidence of grade 3-4 leukopenia was declined by 48％ and 63％( P=0. 098) , and the incidence of grade 3-4 neutropenia was decreased by 34％ and 65％( P=0. 002) , the incidence of grade 3-4 anemia was reduced by 38％ and 10％(P=0. 024), and the incidence of grade 3-4 thrombocytopenia was declined by 40％ and 14％( P=0. 003) . The incidence rate of grade 2 pneumonitis ( P=0. 625) and grade 3 esophagitis ( P=0. 484) were similar in both groups. No patients experienced ≥grade 3 pneumonitis or ≥ grade 4 radiation esophagitis. Conclusions Pemetrexed-cisplatin combined with chemoradiotherapy yields higher clinical efficacy compared with docetaxel-cisplatin plus concurrent chemoradiation in the treatment of stageⅠV lung adenocarcinoma. The incidence of radiation pneumonitis and esophagitis is similar. The incidence and severity of hematological toxicity does not significantly differ between two groups.Treatment-related toxicity is tolerable in both groups.

BACKGROUND: Kinesio taping combined with manual lymphatic drainage for lower limb swelling and pain after total knee arthroplasty (TKA) has not been reported. The existing studies mainly concentrate on the instant effect of kinesio taping, and there is a lack of clinical research on its long-term effectiveness.OBJECTIVE: To observe the curative efficacy of kinesio taping combined with manual lymphatic drainage for lower limb swelling and pain after TKA.METHODS: Sixty patients with lower limb swelling following TKA were randomly divided into control and experimental groups (n=30 per group), followed by treated with kinesio taping, and kinesio taping combined with manual lymphatic drainage, respectively. The swelling degree, visual analogue scale scores and curative efficacy at baseline and 10 days after treatment were compared between two groups.RESULTS AND CONCLUSION: (1) The swelling degree and visual analogue scale scores were significantly decreased in the two groups after treatment (P < 0.05). Compared with the control group, all indicators were significantly improved in the experimental group (P < 0.05). (2) The total effective rate was 80% in the control group and 100% in the experimental group, and the obvious effective rate was 37% in the control group and 63% in the experimental group,both showing significant differences (P < 0.05). (3) These results suggest that the combination of kinesio taping and manual lymphatic drainage can markedly alleviate the low limb swelling and pain after TKA compared with single kinesio taping.

Objective:To explore the clinical application values of contrast-enhanced ultrasound in the diagnosis and classification of portal vein tumor thrombosis (PVTT)by comparing with enhanced CT.Methods:43 patients with PVTT confirmed by clinic and pathology were selected, and the accuracy rates of the diagnosis and clinic classification of contrast-enhanced ultrasound and enhanced CT were compared. Results:The characteristic of PVTT in contrast-enhanced ultrasound was“quick in fast out”;88.4% (38/43)of PVTT were hyper-enhancement in the arterial phase, 81.4% (35/43 ) of PVTT were hypo-enhancement in the vein phase, and all tumor thrombosis showed hypo-enhancement in the delay phase. The diagnostic accuracy rate of contrast-enhanced ultrasound in PVTT was 100%,and the accuracy rate of enhanced CT was 97.7% (42/43).The classification accuracy rate of contrast-enhanced ultrasonic was 95.3% (41/43),and the accuracy rate of enhanced CT was 93.0% (40/43 );there was no statistically significant difference between two methods (P > 0.05 ). Conclusion:Dynamiccontrast-enhanced ultrasonography can display the blood perfusion characteristics of PVTT, and displays the actual infiltrating tumor thrombosis. Ultrasonic imaging and enhanced CT in the qualitative diagnosis of PVTT and clinical classification have a good consistency.Contrast-enhanced ultrasound can be used as an important imaging method to evaluate the PVTT before treatment.

Objective To investigate whether the hyperintensity on T2?weighted MRI affects the outcome of cervical ar?throplasty (CA) for cervical spondylotic myelopathy (CSM). Methods 69 patients with CSM who had undergone CA between June 2005 and December 2007 were retrospectively reviewed. They were divided into three groups according to the intensity of T2?weighted images:Group A, whose intensity of T2?weighted images in spinal cord compression spot was equisignal;Group B, hyper?intensity with obscure border; Group C, hyperintensity with clear border. There were 22 males and 19 females in group A aged from 27 to 63 years old, whose duration of disease was between 3 to 72 months, and there were 34 single?segment cases, 5 double?segment and 2 triple?segment cases. There were 9 males and 9 females in group B aged from 30 to 61 years old whose duration of disease was between 3 to 24 months, and there were 12 single?segment and 6 double?segment cases. There were 4 males and 6 fe?males in group C aged from 28 to 56 years old whose duration of disease was between 1 to 24 months, and there were 8 single?seg?ment and 2 double?segment cases. Two types of artificial cervical disc were used:Bryan Disc in 42 cases and Prodisc?C in 44 cas?es. The duration of Group A (24.7 ± 27.9 months) was significantly longer than that in Group B (6.6 ± 7.4 months) and Group C (11.1±9.5 months). The follow?up period was from 48 to 86 months with an average time of 61 months. The preoperative X?ray and MR as well as postoperative X?ray were collected. The history, compress ratio of MRI, the ROM of cervical segments pre and post?operatively were recorded and Japanese Orthopaedic Association (JOA) was used to evaluate the neurological function. Results Preoperative compress ratio of MRI were 43.3%± 15.2%, 42.4%± 10.7%and 41.9%± 14.8%respectively;preoperative segmental ROM were 9.6°±2.5°, 9.0°±1.7° and 9.1°±1.9° respectively. Preoperative JOA score were 13.6±1.2, 13.1±1.3 and 12.9±1.8, re?spectively. Postoperative JOA score at the latest follow?up were 16.2±1.0, 15.8±1.2 and 15.7±1.6 respectively. There was no statis?tic difference among these groups. Preoperative increased signal intensify on T2?weighted MRI in patients with cervical spondylot?ic myelopathy may not affect the outcome of cervical arthroplasty.
