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.

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 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.

Objective By testing the particle removal efficiency of LG Electronics Company's two types of plasma air cleaners,to explore more scientific and reasonable methods for evaluating the purifying effectiveness of indoor air cleaners so as to obtain scientific and contrastable experimental data and calculating results. Methods This evaluating method referred to Standard Examination Method of Portable Household Electric Cord-Connected Room Air Cleaners of America (ANSI/AHAM AC-1-2000) and used one of indexes regu lated in standard Clean Air Delivery Rate (CADR) as the main evaluating index of the effectiveness of indoor air cleaners,meantime several kinds of domestic and international current evaluating indexes were adopted to synthetically evaluate decontaminating function of the air cleaners. Results The index of CADR could accurately and objectively manifest the true decontaminating function of indoor air cleaner. But if using the index of purifying efficiency to reflect the purifying effectiveness of air cleaners,pollutant's natural decay rate and initial concentration should be considered and at the same time other experimental conditions should be given out. Conclusion The establishments of accurate testing methods and accurate expressions of testing results were the sufficient and essential conditions for accurate evaluation on testing objectives.

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.

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.

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.
