Background and purpose:The occurrence and development of lung cancer are closely correlated with the immune function in the human body.The patients with malignant tumors have shown a disorder of immune function,especially in terms of loss of cellular immune function.The purpose of this study was to investigate the possible auxiliary effect of sipulin in the treatment of advanced non-small-cell lung cancer(NSCLC).methods: Ninety-three patients were randomly divided into two groups:sipulin group:sipulin plus docetaxel+cisplatin;control group:only administered docetaxel+cisplatin.The leukocyte,haemoglobin and platelet,toxicity of digestive tract,body weight,Karnofsky status and efficacy of those patients were evaluated before and after therapy,respectively.Results: Overall response rates were 46.67% and 30.23%(P=0.023)in sipulin group and control group,respectively.The median survival time was 10.1months versus 8.3 months(P=0.035)in sipulin group and control group,respectively.The 1-year survival rate for sipulin group and control group was 52.9% versus 39.4%(P=0.038),respectively.The clinical efficacy and the frequence of leukocyte reduction were better in sipulin group than in control group,the quality of life and clinical symptom of the patients in sipulin group were improved more significantly than those in control group (P

A research combined trickling filter system and active sludge aeration system was applied in the treatment of industrial wastewater from gas-generating with heavy oil. The wastewater contained both high contents of NH+4-N and mixed hydrocarbons including various PAHs. Its BOD5/COD ratio was less than 0.3 and belongs to recalcitrant, toxic wastewater. The results showed a touch-growth biofilms system was formed on the porous packing material and it played a key role in the decrease of toxicity of the influent. It could also improve the biodegradability of the wastewater.

Transforming growth factor-?1 (TGF-?1) was reported to play an important role in the pathogenesis of asthma in many stu-dies.It can stimulate the growth of fibroblast and give rise to fibrosis of lung tissues.Many scholars think that TGF-?1 is closely related to airway remodeling.It is a breakthrough to aim at TGF-?1 to find a way to intervene remodeling in asthma.Glucocorticoid (Dexamethasone and Budesonide) can have an impact in some extent to airway remodeling.In addition,interferon-? and some traditional chinese medicine such as ligustrazine,tripterygium wilfordii and ginkgo maybe effective,they all may ameliorate the progression of airway remodeling following redu-cing partial airway TGF-?1 expression.

Background The condition of the sclera is associated with many ocular diseases.The measurement of human scleral thickness in vivo is helpful for us to understand the features of the sclera and related diseases.Objective The present study was to measure the anterior sclera thickness(AST) in patients with senile cataract and to analyze the relationship among AST and other associated ocular parameters.Methods This study was approved by the Ethic Commission of First Hospital of Peking University.Written informed consent was obtained from each individual prior to examination.One hundred and five senile cataract patients were recruited in this study.Central corneal thickness (CCT),corneal curvature (CCV) and axial length were measured using ultrasonic pachymeter,keratometer,and A-scan unit,respectively.The AST was measured at 2 mm posterior to the scleral spur in the temporal meridian using ultrasound biomicroscope (UBM).The differences of CCT,CCV,ocular axial length and AST between bilateral eyes and the different sexes were compared by the Paired test and independent sample t test.The correlations among various parameters were assessed by the Pearson linear correlation analysis.The differences of CCT and AST among different axial length groups were evaluated by one-way ANOVA.Results No significant differences were found in the CCT,CCV,axial length and AST between bilateral eyes (t =0.584,P =0.561 ; t =1.161,P =0.248 ; t =0.140,P =0.889 ; t =0.342,P =0.773).Temporal AST at 2 mm posterior to the sclera spur was (0.589 ±0.051)mm in the right eyes.An insignificant decline in CCT was found in the male group compared with the female group (right eyes:t =0.469,P =0.641 ; left eyes:t =0.465,P =0.643).However,compared with the female group,the increase of axial length,reduction of the mean CCV value and enhancement of the mean AST were observed(right eyes:all P＜0.01 ;left eyes:all P＜0.01).CCV showed a negative correlation with ocular axial length (r =-0.50,P＜0.01),but no significant correlation was found among age,CCT,ocular axial length and AST(P＞0.05).No remarkable differences were found in CCT and AST among the various axial length groups (CCT:F =0.998,P=0.372;AST:F=1.919,P=0.383).Conclusions In senile cataract patients,correlation is not found between AST and CCT;the increase of axial length is not associated with the thinning of the eyeball wall to a certain extent.Differences exist in some ocular parameters between different sexes.

Background A close relation between sclera thickness and glaucoma has been determined.Clinical features vary in different types of glaucoma patients,which hints that the scleral thickness might be distinct among these patients.Objective The aim of this study was to investigate the differences of central corneal thickness(CCT),anterior scleral thickness(AST) and axial length in glaucomatous patients.Methods This study was approved by the Ethic Commission of First Hospital of Peking University.Written informed consent was obtained from each individual prior to the examination.A retrospective descriptive study was designed.One hundred and sixty consecutive patients were recruited from March,2009 to November,2010 in First Hospital of Peking University,including 35 eyes with primary angle closure glaucoma(PACG) (35 cases),34 eyes with primary open-angle glaucoma POAG) (34 cases),37 eyes with normal tension glaucoma(NTG) (37 cases)and 17 eyes of ocular hypertension OHT) (17 cases).Thirty-seven eyes of 37 subjects with incipient cataract served as the control group.CCT and ocular axial length were measured with ultrasonic pachymeter and A-scan unit,respectively,and AST at the temporal quadrant 2 mm posterior to the scleral spur was measured by ultrasonic biomicroscopy (UBM).The measuring parameters among different groups were compared by analysis of covariance,and the correlations of AST,CCT with ocular axial length were analyzed using Pearson linear correlation and linear regression.The differences and correlation of CCT,AST and AL among five groups were analyzed.Results The CCT values in PACG group,POAG group,NTG group,OHT group and control group were (535.54 ± 5.20),(550.47 ± 5.28),(521.61 ± 5.07),(575.75 ± 7.76) and (535.06± 5.06) μm,respectively,showing a significant difference among them (F =9.560,P =0.000),and the CCT value of OHT group was increased in comparison with POAG group,PACG group,NTG group and control group(all P =0.000).The CCT of the POAG group was thicker than that in the PACG group,NTG group and control group(P=0.046,0.000,0.040).No significant difference was found in CCT among NTG group,PACG group and control group(P=0.950,0.060).The AST values of PACG group,POAG group,NTG group,OHT group and control group were(0.593±0.050),(0.600±0.050),(0.592-±0.060),(0.610-±0.060) and(0.604±0.060) mm,respectively,showing a insignificant difference among them (F =0.700,P =0.590).The axial length in the patients with PACG was shorter than that of the POAG group,NTG group,OHT group and control group (all P =0.000).The Pearson correlation analysis showed significantly positive correlation between CCT and AST in POAG group and NTG group(r=0.445,P=0.008;r=0.400,P=0.014).Conclusions This study confirms that there is dissimilarity in CCT but not in AST among different types of glaucomatous patients.The changes of CCT and AST are consistent in POAG and NTG patients.
