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

A comparison of plant and animal stem cells can highlight core aspects of stem-cell biology. In both kingdoms, stem cells are defined by their clonogenic properties and are maintained by intercellular signals. The signaling molecules are different in plants and animals stem cell niches, but the roles of argonaute and polycomb group proteins suggest that there are some molecular similarities.

Objective To determine if propofol-remifentanil and isoflurane have any different effects on intrapulmonary shunt during one-lung ventilation (OLV). Methods Twenty-four ASA Ⅰ or Ⅱ patients (18 male, 6 female) aged 42-69 yr undergoing radical esophagus cancer resection via left thoracotomy were randomly divided into 2 equal groups ( n = 8 each) : propofol group (Pro) and isoflurane group (Iso) . The preoperative lung function was normal in both groups. The patients were premedicated with intramuscular diazepam 10 mg and atropine 0.5 mg. Radial artery was cannulated and S-G catheter was placed via right internal jugular vein in pulmonary artery. Anesthesia was induced with propofol 1.5-2.0 mg?kg-1, fentanyl 4 ?g?kg-1 and succinylcholine 1.5 mg?kg-1 and maintained with TCI of propofol and remifentanil (target plasma concentration was set at 3.2 ?g?ml-1 and 4.5 ng?ml-1 ) or isoflurane inhalation ( end- tidal isoflurane concentration = 1.5% -2.5 % ) and intermittent i. v. boluses of fentanyl. The patients were mechanically ventilated after endobronchial intubation with double-lumen tube (VT = 8-10 ml, RR= 10-12 bpm, I:E = 1:2) . During OLV VT was reduced to 6-8 ml and RR increased to 14-16 bpm.PaCO2 was maintained at 35-45 mm Hg. ECG, HR, MAP, SpO2, auditory-evoked potential index (AAI), cardiac index (CI), airway pressure and end-tidal isoflurane concentration were continuously monitored during operation. Blood samples were taken from radial artery and pulmonary artery at 10 min after S-G catheter placement (T0, baseline) at 10 min bilateral ventilation (in right lateral position) (T1) at 15, 30, 60, 90 min of OLV (T2-5) for measurement of blood gases and calculation of Qs/Qt.Results The two groups were comparable with respect to age, M/F ratio, body weight and preoperative lung function. AAI was below 30 during operation and PaCO2 and pH were within normal range in both groups. Qs/Qt was significantly increased while PaO2 was significantly decreased during operation (from T1 to T5 ) as compared to baseline values (T0) but Qs/Qt was gradually decreasing while PaO2 was gradually increasing from T2-5 in both groups. Qs/Qt was significantly lower in Pro group than in Iso group at each interval (T2-5) but there was no significant difference in PaO2 at T2-5 between the two groups. Conclusion There is less intrapulmonary shunt during OLV under general anesthesia with propofol-remifentanil than with isoflurane but the difference is not significant enough to affect PaO2.

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.

One carboxypeptidase producing strain was obtained from 28 proteinase producing strains, by analyzing the products of peptides hydrolyzed by the enzyme of the strains According to the characteristics of the morpha and the colonies, the screened strain belongs to aspergillus genera The activity of its carboxypeptidase reached maximum at the 84th hour after fermentation

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。

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.

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.

Antiangiogenesis therapy is one of the most common anticancer therapies. Bevacizumab is a monoclonal antibody that blocks the binding of the vascular endothelial growth factor to its high-affinity receptors. It is the only antiangiogenic agent approved for the first-line treatment of advanced non-small cell lung cancer (NSCLC). Many recent studies have attempted to determine the suit-able partners of bevacizumab in first-line treatment of NSCLC and evaluate its efficacy and safety as a second-line or beyond and con-tinuous treatment of beyond disease progression in patients with advanced NSCLC. This review summarizes current clinical research about the efficacy and safety of bevacizumab in the treatment of advanced NSCLC.

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.
