ABSTRACT
BACKGROUND@#Currently, the prognosis of lobectomy and sub-lobectomy for the treatment of stage Ia small cell lung cancer (SCLC) is rarely reported. We retrospectively studied T1N0M0 (≤3 cm) SCLC patients aged ≥60 years, aiming to comparatively analyze the prognosis of lobectomy and sub-lobectomy in treating patients with Ia SCLC.@*METHODS@#Patients with stage Ia SCLC diagnosed by pathologic between 1992 and 2010 were selected from the "Surveillance, Epidemiology and End Results database"(SEER). Outcome data were compared using Kaplan-Meier (Log-rank test) and Cox model multivariate analysis.@*RESULTS@#We identified 515 patients. Median overall survival (OS) of the lobectomy (n=110), sublobar resection (n=57) and non-surgical (n=348) cohort were 45, 23 and 16 months, respectively. The corresponding 5-year OS of the three groups were 44%, 30%, and 14%, respectively. No significant difference in the prognosis of patients with or without lymph node examination/ dissection (P=0.107) and the 5-year OS of patients underwent lobectomy with chemoradiation was 50%. Cox multivariable analysis showed that operation treatment, including lobectomy and sublobectomy, was one of the independent factors associated with the prognosis of early SCLC patients, and patients undergo lobectomy shows a better OS compared with sublobar resection (Lob vs Sub, HR=0.645; 95%CI: 0.433-0.961, P=0.031).@*CONCLUSIONS@#For age ≥60 years T1N0M0 (≤3 cm) SCLC patients, we recommend anatomical lobectomy combined with adjuvant chemoradiation.

Objective To review the pathogenesis of osteoarthritis ( OA) and microsphere delivery systems advances in the field of osteoarthritis treatment, and provide theoretical support for clinical research and osteoarthritis therapy.Methods The literatures on osteoarthritis have been reviewed in recent years, and pathogenesis and osteoarthritis therapy were summarized.ResuIts At present, the therapy of OA was gradually from symptoms relief to pathogenesis, and further revealed the inner regularity of osteoarthritis treatment.However, a variety of western medicines had its own limitations. ConcIusion In recent years, intra-articular injection therapy because of its unique advantages in clinical treatments,attracts widespread attention, and particularly the microsphere injection with superior prospects is researched more in the field of new formulations.
ABSTRACT
Objective To study optimal compatibility scheme of vidarabine monophosphate for injection combined with aciclovir injection. Methods L18(35) of orthogonal design was used with five factors: temperature, illumination,storage time,solvent and solvent dosage;the insoluble particles were observed by GWJ-4 type particle analyzer.The content of vidarabine monophosphate and aciclovir was detected by HPLC.Optimization of the best scheme of vidarabine monophosphate for Injection combined with aciclovir injection was studied.Results The regression equation of vidarabine monophosphate and aciclovir were A=3.78 ×104C+2.32, r=0.9997(n=5)and A=7.11 ×105C-4.65, r=0.9995(n=5),The results showed that the relationship between the range of 200-900μg/mL(vidarabine monophosphate) and the range of 1000-4500μg/mL(aciclovir) was good.The optimal compatibility conditions are the follows:temperature of 25,as far as possible away from light;Vidarabine monophosphate for injection 1 (0.1 g/branch) and 1 acyclovir injection (10 mL:0.5 g) mixed with 100 mL 0.9% sodium chloride injection,and dropping out within 4 h after compatibility. Conclusion The optimal compatibility scheme has good repeatability,injection solution stability is good.It prouides scientific reference for the safty of clinical rational drug use.
ABSTRACT
Objective To explore the double blood vessels bridge application and efficacy in multiple localized narrow of the anterior descending coronary artery.Methods The clinical data of 106 patients with multiple localized narrow of the anterior descending coronary artery were retrospectively analyzed.The patients were divided into two groups according to the operation methods.Fifty-six patients (improvement group) were conducted double blood vessels bridge on the anterior descending coronary artery,50 patients (control group) were conducted a single blood vessel bridge on the anterior descending coronary artery.Results The age,sex,body mass index,left ventricular ejection fraction,extracorporeal circulation time,endotracheal intubation time,length of hospital stay between two groups had no significant difference (P ＞ 0.05).One case in improvement group occurred angina pectoris,left ventricular size was (51 ± 6) mm,left ventricular ejection fraction was (60.8 ± 8.0)％.Nine cases in control group occurred angina pectoris,left ventricular size was(43 ± 6) mm,left ventricular ejection fraction was(55.1 ± 10.0)％.There was significant difference between two groups(P ＜ 0.05).Conclusion Double blood vessels bridge is safe and effective in multiple localized narrow of the anterior descending coronary artery.
