Annulate lamellae (AL) in oocytes of eel, Anguilla japonica have been observed with electron microscopy. Two types of AL have been found in the cytoplasm of these cells, one of which is the common type, characterized by a stack of parallelly arranged lamellae with annuli (or rings) as shown in figure 1, another is a rare one, which appears as alternative arrangement of parellel lamellae with annuli and membrane-like structures as shown in figures 2～4. The only difference between them is the presence of membrane-like structure in the latter. The origin and function of the membrane-like structure have not been found out yet. It is suggested that this structure might be similar to above-mentioned lamellae in origin and might be a "buffer" in function.

The changes of some parameters of Gray type Ⅰ synaptic interface in the brain of mice treated with desglycinamide-arginine-8-vasopressin (DGAVP) have been analysed quantitatively two hours after DGAVP injection. The animals were killed and the hippocampus and sensori-motor area of cerebral cortex were prepared for electron microscopy. The electron microphotographs were analysed by IBM-PC computer image processing system. The main results of the experiment are as follows:1. The thickness of postsynaptic density apparently increased in both the sensori-motor area of cerebral cortex and CA_3 area of hippocampus after injection of DGAVP (P

Objective To explore the clinical effects of oxygen-driven atomized inhalation of recombinant human inter-feron-α2a injection in the treatment of infantile capillary bronchitis. Methods 240 infant patients with capillary bron-chitis were assigned to a control group and a treatment group according to their disease conditions, with 120 patients in each group. The control group received regular treatment(oxygen uptake, atomized inhalation of pulmicort respulas+nebulized terbutaline sulphate solution used for anti-inflammation and antiasthma, aspiration of sputum, antibiotics giv-en to infants suspected to be complicated with bacterial infection, intravenous drip of methylprednisolone given to in-fants with severe symptoms, etc.); The treatment group further received oxygen-driven atomized inhalation of 600,000 international units of recombinant human interferon-α2a injection, once a day for 5 days. Clinical effects and main ob-servational indices between the two groups were compared. Results Total effective rate was 95.0% in the treatment group and 78.3%in the control group, and the differences between the two groups were statistically significantly(P<0.05). Alleviating time of asthma, disappearing time of lung rale, time of persistent cough and hospitalization time in the treatment group were all lower than those in the control group, and the differences between the two groups were statisti cally significant (P<0.05). Significant adverse events were not detected during the treatment period of oxygen-driven atomized inhalation of recombinant human interferon-α2a injection applied by the infant patients. Conclusion Oxygen-driven atomized inhalation of recombinant human interferon-α 2a injection in the treatment of infantile capillary bron-chitis has an exact curative effect, and it is safe, which is worthy of clinical pediatric promotion and application.

Objective To investigate the relationships between the expression levels of tumor necrosis factor receptor associated factor 4 (TRAF4) and ribosomal S6 protein kinase 4 (RSK4) protein in gastric cancer tissues and the recurrence after laparoscopic radical gastrectomy. Methods In total, 176 patients were divided into the recurrence and non-recurrence group, and the expression levels of TRAF4 and RSK4 protein in cancer and adjacent tissues and in gastric cancer tissues in the recurrence and non-recurrence group were compared. The influencing factor of recurrence and the efficacy of TRAF4 and RSK4 protein expression in predicting recurrence were analyzed. Results The positive expression rate of TRAF4 protein in gastric cancer tissues was higher than that in adjacent tissues (P < 0.05) and that in the recurrence group was higher than that in the non-recurrence group (P < 0.05). The positive expression rate of RSK4 protein in gastric cancer tissues was lower than that in adjacent tissues (P < 0.05) and that in the recurrence group was lower than that in non-recurrence group (P < 0.05). The largest tumor diameter 5 cm, poor differentiation, TNM Ⅲ stage, depth of invasion T3-T4, lymph node metastasis, absence of adjuvant chemotherapy after operation, positive expression of TRAF4 and RSK4 protein, and regular diet w influenced the post-operative recurrence (all P < 0.05). The accuracy of TRAF4 and RSK4 protein in gastric cancer tissues in combined predicting the recurrence was 83.52%. Conclusion The expression of TRAF4 protein is high, and the RSK4 protein is low in gastric cancer tissue, which are related to recurrence.

Objective To investigate the relationship between mean platelet volume(MPV)and saphenous vein graft restenosis in patients receiving coronary artery bypass grafting(CABG),and to analyze the clinical significance of MPV in the prediction of restenosis after CABG.Methods A total of 354 patients admitted into Tianjin chest hospital from September 2009 to September 2014 with suspected myocardial ischemic events 3 to 5 years after CABG treatment was enrolled for a retrospective analysis.According to the coronary angiography(CAG)results,patients were divided into the vein bridge vascular lesion group(saphenous vein graft diseases,SVGD)(n=233)and the venous bridge vascular patency group(saphenous vein graft,SVG)(n=121).Paired t test was used to analyze the relationship between different factors and the bridge vascular patency.The binary logistic regression was used to analyze the effects of MPV and other factors on bridge vascular patency.Venous bridge stenosis ＞ 50％ was considered to be clinically significant and to damage myocardial blood supply.Results The MPV was higher in the SVGD group than the SVG group [(10.2±1.5)fl vs.(9.6±1.5)fl,P＜0.01].The logistic regression analysis showed that MPV(OR =1.268,95％CI:1.053-1.570,P=0.014),age(OR =1.007,95％CI:1.038-1.117,P=0.000),gender (OR=0.452,95％CI:0.250-0.816,P=0.008),diabetes mellitus(OR=2.319,95％CI:1.221-4.405,P =0.010)were the independent risk factors for venous bridge stenosis in the two groups,gender(OR=0.495,95％CI:0.251-0.976,P=0.042),diabetes mellitus(OR =2.237,95％CI:1.105-4.527,P =0.025),MPV(OR=1.334,95％CI;1.050 1.694,P=0.018),fibrinogen(OR=1.654,95％CI:1.020-2.682,P =0.041)were the independent risk factors for venous bridge stenosis in non-elderly patients,and age(OR =1.178,95％CI:1.116-1.244,P =1.178)was an independent risk factor for vein graft stenosis in elderly patients.The restenosis rate was higher in patients with MPV ≥ 12 fl(92.6％ or 25/27) than in the patients with MPV ＜ 12 fl(63.6％ or 208/327).The receiver operating characteristics(ROC) curve showed that the areas under the curve of MPV,age,gender,diabetes,fibrinogen were 0.610,0.657,0.394,0.626,0.654,respectively,and the area under the curve of joint diagnosis was 0.796,showing that joint prediction value was higher than any single prediction value(P＜0.01).Conclusions MPV level is an independent risk factor for vein graft stenosis,and has higher predictive value in combination with age,gender,diabetes and fibrinogen.
