ABSTRACT
Objective To observe the clinical curative effect of Ⅲb~Ⅳstage non-small cell lung cancer treated by radiofrequency ablation combined with chemotherapy. Methods Forty-eight Ⅲb~Ⅳstage non-small cell lung cancer patients were divided into the study group (RFA + chemotherapy) and 74 were in control group (chemotherapy alone) by the method of non randomized controlled. Curative effect was evaluated every two cycles during the treatment. A 6 to 36 months follow-up was conducted after the treatment. Results The objective response rate of experiment group and control group was 58.3%and 41.9%respectively (P>0.05) with no significant difference and disease control rates of experiment group and control group were 91.7% and 75.7% respectively (P<0.05). MST were 14.4 months and 8.2 months respectively (P<0.01), with statistically significant differences in experiment group and control group and clinical benefit efficient were 87 . 5% and 66 . 2% respectively ( P < 0.05). Conclusion The treatment of radiofrequency ablation combined with chemotherapy for advanced non-small cell lung cancer can significantly improve the patient′s survival and the clinical curative effect.
ABSTRACT
Objective To investigate the influence of Chinese medicine ( CM) treatment on life span of middle-late primary hepatic carcinoma (PHC) patients. Results A multicenter retrospective cohort study was carried out in 489 PHC patients at the stages of Ⅱb, Ⅲa and Ⅲb collected from 15 domestic hospitals. With CM treatment as the exposure factor, the enrolled patients were divided into CM group, western medicine (WM) group and the CM-WM combination group. The main outcomes included median survival time (MST) and survival rate, and the effects of CM treatment and minimally invasive therapy on MST were observed. Results Half-a-year survival rate, one-year survival rate and two-year survival rate were 50%, 9%, 1% in CM group, 70%, 30%, 6% in CM-WM combination group, and 50%, 10%, 0% in WM group, respectively. The survival rates in CM-WM combination group differed from those in CM group and WM group (P0.05) . MST at the stages of Ⅱb, Ⅲa, Ⅲb in CM-WM group was obviously prolonged as compared with the other two groups (P0.05) . CM treatment and minimally invasive therapy were effective on prolonging the survival time of PHC patients ( P<0.01) . The results of COX regressionanalysis showed that Karnofsky scores, CM treatment and minimally invasive therapy were the preventive factors for the prognosis. Conclusion CM-WM combination group has the best long -term therapeutic effect. CM -WM combination treatment is effective on increasing MST and long-term survival rate, in particular for PHC patients at the stages ofⅡb, Ⅲa and Ⅲb. CM treatment and minimally invasive therapy are helpful for the prolongation of the survival time of PHC patients.
ABSTRACT
Objective To analyze the early clinical efficacy of alendronate sodium on residual pain after vertebral angioplasty for osteoporotic vertebral compression fractures.Methods By drug single treatment method,a total of 30 elderly patients with residual pain after vertebral angioplasty for osteoporotic vertebral compression fractures were included.Patients were randomly divided into 2 groups:the treatment group and the control group.All patients were given calcium carbonate D3 treatment,and the treatment group was given alendronate sodium treatment additionally.6 weeks after the treatment,visual analogy score (VAS) was used for the evaluation of pain relief.Results All patients were followed up for 6 weeks.At the end of follow-up,the rates of pain relief were 86.8％ in treatment group and 13.2％ in control group.There was a significant difference in visual analogy scores between the treatment group and the control group[(0.51±0.32),(1.59±1.21) ; t=3.4,P＜0.001],which showed the degree of pain relief was higher in the treatment group than in control group.Conclusions Alendronate sodium is effective and reliable for the treatment of residual pain after vertebral angioplasty for osteoporotic vertebral compression fractures.This study provides the scientific reference for the treatment and research of residual pain after vertebral angioplasty for osteoporotic vertebral compression fractures.
ABSTRACT
Objective To observe the dynamic changes and the effects of Captopril on interstitial fibrosis in lung tissue of neonatal rats with lung fibrosis induced by hyperoxia. Methods Two hundred and forty neonatal Wistar rats were randomly assigned into model group, air control group, normal saline control and Captopril-trcated group (n=60 each).The air control group was exposed to room air (FiO2 = 0.21), and the rest three groups were continuously exposed to hyperoxia (FiO2 = 0.9) for 21 days. During the exposure, the Captopril-treated group received Captopril [ 30 mg/( kg·d) ] by intragastric administration, and the normal saline control group was administrated with normal saline instead, the model group did not receive any treatment. On the 1 st, 3 rd, 7 th, 14 th and 21 st day of exposure, the subjects were sacrificed. And then, the protein levels of collagen Ⅲ (Co-Ⅲ ) were measured by enzyme-linked immunosorbent assay and angiotensin Ⅱ(Ang Ⅱ )by radio-immunity technique, and the mRNA expression of Ang Ⅱ, Co- Ⅲ was measured by RT-polymerase chain reaction. The changes of lung histomorphology were observed. Results On the 14 th day, The Ang Ⅱ, Co- Ⅲ protein levels and their mRNA expression of modal group and normal saline control group increased significantly as compared to the air control group ( P < 0.05 ), except the Ang Ⅱ mRNA expression of normal saline control group. The Ang Ⅱ and Co-Ⅲ protein levels of model group was (838.22 ± 197.75 ) and ( 104.21 ± 43.37) ng/mg respectively, and normal saline control group was ( 759.97 ± 60.81 ) and ( 128.69 ± 54.74) ng/mg respectively on the 21 st day, their mRNA expression of two groups also increased to the peak on the 21 st day(P< 0.05).The AnglI and Co- Ⅲ protein levels of Captopril-treated group was (554.52 ± 59.32) and (39.90 ± 13.45) ng/mg on the 21 st day respectively, their mRNA expression was (1.50 ± 0.84 ) and (1.13 ± 0.55) respectively, and decreased significantly as compared to the model group and normal saline control group respectively (P<0.05), but increased significantly as campared to the air control group (P < 0.05). The histopathological examination demonstrated different degrees of alveolitis, broaden interstitium and reduced alveolar quantity in the model group and normal saline control group compared with air control group. The pathological changes were markedly alleviated in the Captopril-treated group. Conclusion Captopril may have protective effects on lung injury induced by hyperoxia.
ABSTRACT
Objective To investigate the therapeutic effect of ozone in treating the recurrent herniated lumbar disc after surgery.Methods Thirty-seven lumbar discs in 37 patinets with recurrent lumbar disc herniation after surgery were injected with ozone under CT-guided.The operative approaches were via lateroposterior position of lumbar vertebrae in 30 and via posterior position in 7 cases.Results The process of injection was done successfully in all patients.Followed-up for three months to one year after the treatment,the cases of clinical therapeutic efficacy of excellent results were 9,the cases of good results were 22,no changes in 6 cases.Conclusion Ozone in treatment of recurrent herniated lumbar disc after surgery is a safe and effective method.
