ABSTRACT
Objective:To explore the clinical efficacy of different doses of apatinib combined with chemotherapy in patients with advanced non-small cell lung cancer (NSCLC) and the adverse reactions.Methods:A total of 69 patients with NSCLC diagnosed in the No. 901 Hospital of the Chinese People′s Liberation Army Joint Logistics Support Force were selected from January 2018 to June 2020, and were divided into chemotherapy alone group (docetaxel+ cisplatin was used), apatinib group A [apatinib (0.25 g)+ docetaxel+ cisplatin was used] and apatinib group B [apatinib (0.50 g)+ docetaxel+ cisplatin was used] according to random number table method, with 23 cases in each group. The objective response rate (ORR), disease control rate (DCR), median overall survival (OS), median progression-free survival (PFS), and incidences of adverse reactions were compared between the three groups of patients.Results:One patients in the apatinib group B withdrew from the study due to acute myocardial infarction. After 4 cycless of treatment, the ORR of the patients in the chemotherapy alone group, apatinib group A and apatinib group B were 17.39% (4/23), 47.83% (11/23) and 54.55% (12/22) respectively, with a statistically significant difference ( χ2=7.41, P=0.024). The ORR of the apatinib group B was higher than that of the chemotherapy alone group, with a statistically significant difference ( χ2=6.77, P=0.009). There were no statistically significant differences in ORR between the apatinib group A and chemotherapy alone group, the apatinib group A and apatinib group B ( χ2=4.85, P=0.028; χ2=0.20, P=0.652). The DCR of the patients in the three groups were 47.83% (11/23), 78.26% (18/23) and 86.36% (19/22) respectively, with a statistically significant difference ( χ2=9.03, P=0.011). The DCR of the apatinib group B was higher than that of the chemotherapy alone group, with a statistically significant difference ( χ2=7.52, P=0.006). There were no statistically significant differences in DCR between the apatinib group A and the chemotherapy alone group, the apatinib group A and apatinib group B ( χ2=4.57, P=0.033; χ2=0.51, P=0.477). The median OS of the patients in the three groups were 6.8, 9.2 and 9.9 months respectively, with a statistically significant different ( χ2=8.91, P=0.022). Compared with the chemotherapy alone group, the median OS of the apatinib group A and apatinib group B were significantly prolonged, with statistically significant differences ( χ2=7.25, P=0.036; χ2=8.60, P=0.029). Compared with the apatinib group A, the median OS of the apatinib group B was prolonged, but there was no statistically significant different ( χ2=1.54, P=0.201). The median PFS of the patients in the three groups were 5.2, 7.7 and 8.2 months respectively, with a statistically significant different ( χ2=8.79, P=0.026). Compared with the chemotherapy alone group, the median PFS of the apatinib group A and apatinib group B were significantly prolonged, with statistically significant differences ( χ2=7.01, P=0.039; χ2=8.36, P=0.031). Compared with the apatinib A group, the median PFS of the apatinib group B was prolonged, but there was no statistically significant different ( χ2=1.68, P=0.186). There were statistically significant differences in the incidences of fatigue [34.78% (8/23) vs. 65.22% (15/23) vs. 72.73% (16/22), χ2=7.50, P=0.024], hypertension [4.35% (1/23) vs. 34.78% (8/23) vs. 68.18% (15/22), χ2=20.07, P<0.001], hand-foot syndrome [4.35% (1/23) vs. 43.48% (10/23) vs. 72.73% (16/22), χ2=22.28, P<0.001] and oral mucositis [8.70% (2/23) vs. 39.13% (9/23) vs. 72.73% (16/22), χ2=19.26, P<0.001] among the three groups. Compared with the chemotherapy alone group, the incidences of hypertension and hand-foot syndrome in the apatinib group A and the incidences of fatigue, hypertension, hand-foot syndrome and oral mucositis in the apatinib group B were increased, with statistically significant differences ( χ2=6.77, P=0.009; χ2=9.68, P=0.002; χ2=6.51, P=0.011; χ2=20.00, P<0.001; χ2=22.37, P<0.001; χ2=19.21, P<0.001). Conclusion:Apatinib (0.50 g) combined with chemotherapy has better short-term efficacy than chemotherapy alone in advanced NSCLC. Apatinib (0.25 g) and apatinib (0.50 g) can prolong the survival of patients, but increasing the treatment dose can not achieve longer survival benefit.
ABSTRACT
Objective To investigate the short-term clinical efficacy and adverse reactions of stereotactic radiotherapy (SRT) in the treatment of locally recurrent non-small cell lung cancer (NSCLC).Methods Clinical data of 120 cases of recurrent NSCLC after radiotherapy admitted to our hospital from October 2009 to October 2015 were retrospectively analyzed.SRT was adopted for further radiotherapy.The prescription dose was 50％ dose curve surrounding the target area.The total dose was 40-50 Gy,with a single dose of 4-5 Gy for 8-12 times.The chest CT was re-examined every 2 months after radiotherapy.The short-term clinical efficacy and adverse reactions were evaluated.The changes of Karnofsky performance score (KPS) and quality of life (QOL) were recorded before and after radiotherapy.Results One patient terminated the radiotherapy due to grade 3 acute radiation-induced pneumonia,25 patients (21.0％) obtained complete remission (CR),61 cases (51.3％) of partial remission (PR),19 cases (16.0％) of stable disease (SD),14 cases (11.8％) of progress disease (PD),86 cases (72.3％) of objective remission rate (CR+PR),and 105 cases (88.2％) of disease control (CR+PR+SD),respectively.Thirty-one patients experienced radiation-induced pneumonia,23 cases of radiation-induced myelosuppression and 1 case of acute radiation-induced heart injury.All these adverse reactions were mitigated after symptomatic treatment.The KPS was significantly increased from 68.16±15.22 before SRT to 78.39± 11.50 after SRT (P＜0.05).The QOL was considerably elevated from 27.58±5.37 prior to SRT to 38.16±8.39 following SRT (P＜0.01).Conclusion SRT is an efficacious and safe treatment of locally recurrent NSCLC,which yields controllable and tolerable adverse reactions and enhances the QOL of patients.

ABSTRACT
Scoliosis, the abnormal lateral curvature of the spine, is an idiopathic disease often suffered by teenagers. Normally medical doctors use X-rays to measure the Cobb angle, and then assess the severity of scoliosis with it. In this paper, we point out the superiorities of image processing technique through analyzing the existing methods in the diagnosis of scoliosis. Two kinds of image processing technique are mainly introduced for scoliosis detection. The moiré stripe images show an asymmetric deformation pattern between the left-hand side and the right-hand side of human back, and these associate with Cobb angle to detect scoliosis. In order to check scoliosis through accurate three-dimensional surface features of human back, we in the second technique use different optical imaging methods to reconstruct the three-dimensional surface model of the patient's back, and extract the characteristics of the reconstructive human back to diagnose the disease. Both approaches tried to describe symmetry discrimination of human back and correlated it with the Cobb angles. Finally, we look forward to the future development in the application of image processing technique for scoliosis detection.

Objective To study the expressions of the tumor suppressor gene TSH receptor( TSHR),P16, and RAS in papillary thyroid carcinoma ( PTC ) , and the correlation between the occurrence of tumor and the aberrant promoter hypermethylation of three tumor suppressor genes. Methods RT-PCR was used to detect the mRNA expression of three tumor suppressor genes in tissues of 50 cases of PTC ,20 cases of nodular goiter,and 12 cases of thyroid adenoma. The promoter methylation status of three tumor suppressor genes was examined by methylation-specific PCR technique( MSP). Gene sequencing was used to test if the hypermethylation existed in the promoter of three tumor suppressor genes. Results In 68.0% (34/50) TSHR gene, 54.0% (27/50) P16 gene, and 60.0% ( 30/50 ) RAS gene in PTCs, hypermethylation in promoter region was detected, the respective results 21.9% (7/32) , 15. 6% (5/32) ,and 31. 3% (10/32) were found in control tissues. The rates of the three genes with promoter hypermethylation in PTC were significantly higher than those in control tissues ( all P<0. 05). The mRNA expressions of TSHR,P16,and RAS were significantly lower in PTC than those in control tissues (0. 41 ± 0.11 vs 0.63±0. 08,0. 51±0. 17 vs 0. 72±0. 22,0. 56±0. 10 vs 0. 67±0. 16, all P<0. 05). The sequencing confirmed that there was CC to TC transmission in the promoters of three tumor suppressor genes. Conclusions The methylation of three tumor suppressor genes in promoter region is a common molecule event and may be involved in the genesis and development of human PTC.
ABSTRACT
Computed Tomography(CT) is one of the successful methods, in which mathematical theories are combined with engineering technology. Volume CT will replace the cross-sectional CT that has been widely used. In this paper two new cone vertex orbits, which are circle-and-arc and regular triangular pyramid lines, have been proposed and their complete conditions for exact reconstruction have been obtained. After having studied circle-and-n-line cone vertex orbit which is one of the important orbits in volume CT, we have given a better proof about the complete condition in circle-and-line and circle-and-2-line cone vertex orbit and have obtained some proper conclusions. Finally, we extend the above results to circle-and-n-line vertex orbit. These results will be useful for the design of direct volume imaging.
