OBJECTIVE: To evaluate the influence of fewer courses and prolonged intervals of chemotherapy on survival rate of advanced non small cell lung cancer (NSCLC) patients treated by sequential chemo-radiation therapy combined with traditional Chinese medicine (TCM). METHODS: From Jan. 2000 to Dec. 2001, 54 untreated advanced NSCLC patients (2 stage IIIa, 18 stage IIIb, 34 stage IV) were treated by sequential chemo-radiation therapy combined with TCM. The courses of chemotherapy were reduced and the intervals of chemotherapy were longer than that of the standard regimen. The efficacy and survival rate were documented and the prognostic factors were analyzed. RESULTS: Complete remission (CR) was observed in 1 case and partial remission (PR) in 20 cases. The overall objective response rate was 40.4%. Median survival was 15.3 months, 1-, 2- and 3-year survival rate were 53.7%, 28.9% and 9.6% respectively. The median survival of stage III and IV were 21.8 months and 12.5 months respectively. The 1-, 2-, and 3-year survival rates of stage III were 65.0%, 49.5%, 24.7% and that of stage IV were 47.0%, 23.3%, 0%, respectively. The quality of life was improved in most of the patients. Cox's proportional hazards regression showed that improved quality of life and treatment of TCM were the significant prognostic factors of overall survival. CONCLUSION: Chemotherapy and radiotherapy combined with TCM is beneficial to extending the interval of chemotherapy, improving the quality of life, and increasing the survival rate of advanced NSCLC patients.

Objective To evaluate the value of reconstruction of three-dimentional CT in development dislocation of hip(DDH)in children.Methods Twelve cases of DDH concluded 4 bilateral and 8 unilateral cases.To sum up,16 sick hips were operated and 8 normal hips were also obtained by three-dimensional CT(Hip speed Fi/x,GE Co).Results 3D reconstruction were used to show femoral head,(acetabulum) and relationship of acetabulum and femoral head respectively.The difference between FNA measurement of sick hips and those of normal hips were significant(P

Objective To investigate the clinical epidemiologic features of transient synovitis(TS) of hip in children occurred in Shen-zhen district.Methods The medical files were reviewed and a standard questionnaire was filled according to the conditions of 705 cases such as pathogeny,clinical manifestation,therapy and prognosis.Results Transient synovitis occurred in a sporadic form all the year round.The peak age of patients with TS was 3-7 years old.The ratio of boys to girls was 2.9:1.About 19.3% patients were attacked an upper respiratory tract infection and 11.9% patients attributed the symptoms to trauma or severe activities before 1 week.A varying degree of painful limp and restriction of movement at the hip were found clinically.All of cases were cured by skin traction.The incidence of recurrence was 6.95%.Conclusions Male predominance is found in TS.It is characteristic of sporadic form in the 4 seasons and intently relation to an upper respiratory tract infection and trauma or severe activities.TS is recurrent and the prognosis is good by skin traction.

To investigate the therapeutic effect of artesunate on mouse cytomegalovirus pneumonia, the BALB/c-nu mice were infected with murine cytomegalovirus-green fluorescent protein (MCMV-GFP) by nose dropping method. The experimental protocol was approved by the Medical Laboratory Animal Ethics Committee of Guangzhou Medical University. The BALB/c-nu mice were randomly divided into five groups: control group, MCMV pneumonia group, and artesunate (60, 120, and 240 mg·kg^-1) groups. The survival rate, weights, and virus loads in lungs among the groups were observed. The degree of histopathologic changes in lungs was assessed directly by hematoxylin-eosin (HE) assay. MCMV-GFP expression was assessed by immunofluorescence. In addition, reverse transcription polymerase chain reaction (RT-PCR) analysis was performed to investigate the content of major immediate early 1 (Mie1) mRNA, and enzyme-linked immunosorbent assay (ELISA) was used to detect the changes of inflammatory factors, interleukin 10 (IL-10), IL-6, and tumor necrosis factor-α (TNF-α). Western blot analysis was used to detect the expression of the changes of nuclear factor-kappa B (NF-κB) signaling pathways in total proteins. Compared with MCMV group, artesunate (120 mg·kg^-1) significantly increased body weights of MCMV-infected nude mice over 30 days, and decreased the viral titer in lung homogenate, lung inflammation, and histological severity. Moreover, the administration of artesunate (120 mg·kg^-1) could downregulate the expression of phospho-NF-κB (p-NF-κB) p65 in the lungs of mice. The present study suggested that artesunate can protect the immunocompromised mice from MCMV-induced interstitial pneumonia via downregulating NF-κB signaling pathway, thus attenuating inflammation in the lungs.

Water soluble extract (WSE) is an important index for the quality evaluation of Astragali Radix (AR). In this study, the WSE of the wild AR from Shanxi province (SX) and the cultivated AR from Gansu Province (GS) were compared. The WSEs of two types of AR were determined according to the appendix of Chinese pharmacopoeia. Then the WSEs were subjected to NMR analysis, and the obtained data were analyzed using HCA, PCA, OPLS-DA, microarray analysis, and Spearman rank analysis. In addition, the Pearson correlation of differential metabolites were also calculated. The results showed that the WSE content of GS-AR (37.80%) was higher than that of SX-AR (32.13%). The main constituent of WSE was sucrose, and other 18 compounds, including amino acids, organic acids, were also detected. Multivariate analysis revealed that SX-AR contained more choline, succinic acid, citric acid, glutamate, taurine and aspartate, while GS samples contained more sucrose, arginine and fumaric acid. In addition, the Pearson correlations between different metabolites of the two types of AR also showed apparent differences. The results suggested that the WSE of two types of AR differs not only in the content, but also in the chemical compositions. Thus, the cultivation way is important to the quality of AR. This study supplied a new method for the comparison of extract of herbal drugs.

Objective To explore the diagnosis and TNM stage effect of serum CYFRA21-1,VEGF and PDGF in patients with non-small cell lung cancer.Methods The electrochemiluminescence immunoas- say was used to detect serum CYFRA21-1,and the sandwich enzyme-linked immunoabsorbentassay(ELISA) was used to detect serum VEGF and PDGF in patients with non-small cell lung cancer and 30 normal healthy controls.Results Compared with healthy control group,the level of serum CYFRA21-1,VEGF and PDGF in non-small cell lung cancer group were much higher(P0.05).The serum CYFRA21-1 level was positively correlated with VEGF and PDGF(P

?AIM: To retrospectively analyze the surgical strategies and outcome of traumatic lens dislocation.?METHODS: Retrospective study. Clinical data of 105 cases ( 105 eyes ) diagnosed with traumatic lens dislocation from April to June 2014 in our hospital were recruited. According to position of dislocated lens and complicated situations, different surgical approaches were performed, including intracapsular lens extraction, phacoemulsification, vitrectomy through pars plana and lensectomy. Meanwhile, vitreo-retinal or anti-glaucoma surgeries were performed in complicated cases. Preoperative and postoperative LogMar ( Logarithm of the Minimum Angle of Resolution ) visual acuity were compared by paired t-test. Perioperative complications including expulsive choroidal hemorrhages and recurrent retinal detachment were recorded and assessed.?RESULTS: All 105 dislocated lenses were removed completely. Visual acuity of 91 eyes ( 86. 7%) were significantly improved postoperatively. The visual acuity of most patients was 0. 1-0. 3 ( 42 eyes, 40. 0%) and 1 patient’s visual acuity with lens subluxation reached more than 0. 8 postoperatively. Expulsive choroidal hemorrhages occurred in 1 eye intraoperatively and 1 eye postoperatively. Recurrent retinal detachment was observed in 2 eyes postoperatively.? CONCLUSION: According to position of the lens dislocation, personalized surgery strategy is critical for therapy of traumatic lens dislocation. Expulsive choroidal hemorrhage is one of most several complications and should be managed properly.
