1.SURFACE CYCLODIATHERMY FOR ABSOLUTE GLAUCOMA
Journal of Chongqing Medical University 1987;0(01):-
Twenty two patients with variant types of absolute glaucoma were treated by surface cyc-lodiathermy. Follow-up time averages 3.5 years, without medication, intra-ocular pressure (IOP) was well controlled in 13 patients; IOP was decreased by 50% and the symptoms were relieved in two patients. The effective rate was 68%. In this paper, the technique and comp-lication of this operation were introduced. The technique rather simple. The effect of the operation is satisfactory, and complication is few. Therefore, we adopt cyclodiatharmy is a better procedure for absolute glaucoma

Objective To evaluate the clinical efficacy of sodium tanshinone IIA sulfonate(STS)in the treatment of ad-vanced schistosomiasis. Methods Fifty cases with advanced schistosomiasis admitted to the Touzao Township Hospital of Dong-tai City during the period from November 2012 to November 2013 were treated with STS for 10 days,and the internal diameter of the portal vein,levels of ALT,AST,γ-GT,PIIIP,CIV,HA and LN were measured and compared before and after the adminis-tration of STS. Results The mean levels of all serological parameters except HA were within the normal range before STS treat-ment,while the highest positive rate was detected inγ-GT(26.0%)and HA(54.0%). Following the STS treatment,the mean lev-els of all parameters and the positive rates reduced,with the greatest reduction observed inγ-GT(36.7%)and HA(37.8%);how-ever,the mean HA level was still higher than the normal range. The mean internal diameter of the portal vein reduced from(10.5± 1.7)mm before the STS treatment to(9.8±1.3)mm after the STS administration,with a significant diffrtence(P<0.05). Conclu-sion STS appears effective in the treatment of advanced schistosomiasis.

There exist all kinds of corrupt behaviors in the fields of scienceat present, which result not only from the ethics of editors and legal supervision, but also from the institutional cause. To counter this phenomenon, this article analyzed current situation and the reason of academic corruption by literature and brought forward the conclusion that how to strengthen system control against academic corruption. The scientific research management should make polices and rules for anti -academic corruption, including defining,allegation, prevention and sanction, etc.

Levels of lipids, lipoproteins and apolipoproteins in 59 patients with cerebral infarction were compared before and after therapy. Evening—Primrose—oil group (EPOG 32cases) was treated with EPO and routine drugs (low molecular dextran, piracetam, vitamine E), the routine—drug group (RDG 27cases) was treated only with above- mentioned routine drugs. After treating for one month the lab data demonstrated that the(HDL—c, HDL2—c and apo A—I levels in EPOG were significantly higher than)before treating (P0.05). All parameters above- mentioned in RDG had no significant change after treating.

Effects of carbon resource, nitrogen resource, metal irons and surface detergents on the production of pro topectinase by strain Aspergillus sp XZ 131 were studied The results showed that pectin substances were essential for the strain to produce protopectinase The enzyme activity reached to 300 U/mL, when(NH 4) 2SO 4 and(NH 4) 2HPO 4 were used as nitrogen resource Ca 2+ and Tween 20 were able to enhance the production of the enzyme The optimum composition of the medium was citrus peel powder 1g,(NH 4) 2SO 4 2g,CaCl 2 0 015g,Tween 20 0 2mL,KH 2PO 4 3 8g,K 2HPO 4?3H 2O 0 2g,H 2O 100mL,pH 6 5。
7.Therapeutic strategies and relevant clinical problems in non-small cell lung cancer with brain metastases
Chinese Journal of Clinical Oncology 2015;42(19):947-952
Brain metastasis is among the most common complications of non-small celllung cancer (NSCLC) and may obviously influence the survival and quality of life in the NSCLC patients. Recently, the development in traditional treatments, the widely-used micro-molecular targeted drugs, and the combined treatment have improved the overall survival and the quality of life of these patients. In addition, the exploration of new therapeutic targets and cognitive function protective methods for current treatments also deserves at-tention. This review emphasizes the relevant clinical and basic problems and the therapeutic strategies in NSCLC with brain metastases.

Objective To evaluate the effects of ischemic postconditioning on nuclear factor kappa B (NF-κB) and intercellular adhesion molecule-1 (ICAM-1) expression during lung ischemia-reperfusion (I/R) injury in a dog model of cardiopulmonary bypass (CPB), and further investigate the pulmonary protection induced by ischemic postconditioning and the underlying mechanism.Methods Twelve adult mongrel dogs of both sexes, weighing 12-15 kg, were randomly divided into either CPB group or ischemic postconditioning group (IPO group) using a random number table, with 6 dogs in each group.CPB was established after the chest was opened in dogs anesthetized with pentobarbital sodium.Ischemic postconditioning was induced by 2 cycles of 5 min reperfusion followed by 5 min ischemia immediately after occlusion of the left pulmonary artery was released in group IPO.Before CPB (T1), before occlusion of the artery was released (T2) , and at 2 h after termination of CPB, lung specimens were obtained for examination of pathological changes which were scored (with light microscope) and for determination of the expression of NFκB and ICAM-1 (using Western blot) and wet/dry lung weight ratio (W/D ratio) in left lung tissues.Blood samples were collected from femoral arteries at T1 and T3 for blood gas analysis, and oxygenation index (OI), respiration index (RI) and dynamic lung compliance (Cdyn) were calculated.Results OI and Cdyn were significantly decreased, and RI was increased at T3 , and W/D ratio, pathological scores, and expression of NF-κB and ICAM-1 were increased at T2,3 than at T1 in the two groups.W/D ratio, pathological scores, and expression of NF-κB and ICAM-1 were significantly higher at T3 than at T2 in the two groups.Compared with group CPB, OI and Cdyn were significantly increased, and R1, W/D ratio, pathological scores, and expression of NF-κB and ICAM-1 were decreased at T3 in group IPO.Conclusion Ischemic postconditioning up-regulates the expression of ICAM-1 through inhibiting NF-κB activity, thus reducing lung I/R injury induced by CPB and improving the lung function in dogs.

Currently, histological and molecular methods are considered for the treatment of advanced non-small cell lung cancer (NSCLC). Single-agent epidermal growth factor receptor tyrosine-kinase inhibitors (EGFR-TKIs) and anaplastic lymphoma kinase in-hibitors (ALK-TKIs) have been used as standard first-line therapies for patients with active EGFR mutation and ALK rearrangement, re-spectively. However, to date, the single-agent EGFR-TKIs as the first-line therapy for patients with known EGFR mutations has been demonstrated to provide a prolonged progression-free survival but does not affect overall survival (OS). Physicians these days focus on improving the OS of patients with advanced NSCLC. To patients with EGFR mutation, combining and maintaining EGFR-TKIs with chemotherapy could be a promising approach. In this article, various ways of combining EGFR-TKIs with chemotherapy were explored.

A series of 5-amino-2-( benzylthio ) thiazole-4-carboxamide derivatives were designed and synthesized to discover novel compounds with anti-tumor activity. Compounds DDO-5401-DDO-5416 were synthesized using 2-amino-2-cyanoacetamide as the start material. The structures of the synthesized compounds were confirmed by IR, 1 H NMR and ESI-MS. The in vitro anti-tumor activities of the synthesized compounds were determined by MTT assay in HCT116 , HepG2 , A549 , MDA-MB-231 and MCF-7 cell lines. Target compounds showed good anti-tumor activity especially in A549 cell line. SAR study showed that electron donating groups were more favorable than electron absorption ones. Compound DDO-5413 exhibited noteworthy activity in MDA-MB-231 and MCF-7 cell lines with IC50 value lower than the positive reference dasatinib. It suggested that DDO-5413 might be the candidate for further investigation.
