Effects of different levels of ophthalmic surgical stimulation on blood glucose changes in patients with type 2 diabetes mellitus / 沈阳医学院学报

Objective:To investigate the effects of different levels of ophthalmic surgical stimulation on blood glucose in patients with type 2 diabetes mellitus(T2DM).Methods:From Mar to Oct 2021,236 patients with T2DM who underwent ophthalmic surgery in our hospital were enrolled,including 71 cases of secondary surgery,89 cases of tertiary surgery,and 76 cases of quaternary surgery.According to the operation time,the 236 patients were divided into groups A(＜60 min),B(60-120 min)and C(＞120 min).The preoperative and postoperative blood glucose levels were compared in patients with different levels of surgery,and in groups A,B and C.Results:The postoperative blood glucose level was lower than that before surgery in secondary and tertiary surgery,and it was higher than that before surgery in quaternary surgery(P＜0.05).The fluctuation value of blood glucose in secondary and tertiary surgery was higher than that in quaternary surgery(P＜0.05).In groups A,B and C,the postoperative blood glucose level was lower than that before surgery in secondary and tertiary surgery(P＜0.05).In group A,there was no significant difference in the blood glucose before and after surgery in quaternary surgery(P＞0.05),and in groups B and C,the postoperative blood glucose was higher than that before surgery in quaternary surgery(P＜0.05).In group A,there was no difference in the fluctuation value of blood glucose at different levels of surgery(P＞0.05).In group B,the fluctuation value of blood glucose in patients with secondary and tertiary surgery was higher than that in quaternary surgery(P＜0.05).In group C,the fluctuation value of blood glucose in patients with tertiary and quaternary surgery was higher than that in patients with secondary surgery(P＜0.05).Conclusions:For ophthalmic surgery patients with T2DM,the postoperative blood glucose values of patients undergoing secondary and tertiary surgery generally show a downward trend,while the postoperative blood glucose value of patients undergoing quaternary surgery generally shows an upward trend.It is suggested that clinical workers should actively manage the perioperative blood glucose of patients with high-level surgery.

Two diterpenoids from herbs of Huperzia serrata / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the constituents from Huperzia serrata.</p><p><b>METHOD</b>Two diterpenoid compounds were isolated by column chromatography with silica gel and Sephadex LH-20. The structures were elucidated by spectral analysis and X-ray crystallographic analysis.</p><p><b>RESULT</b>Their structures were determined as (15R)-12, 16-epoxy-11, 14-dihydroxy-8, 11, 13-abietatrien-7-one (1) and 3beta-hydroxysandaracopimaric acid (2).</p><p><b>CONCLUSION</b>Compound 1 was a new natural abietane-type diterpenoid, compound 2 was isolated from this plant for the first time.</p>

Observation of Bone Marrow from Two Panmyelosis Leukemia Patients by Electron Microscopy and Cytochemistry / 第二军医大学学报

Bone marrow cells from 2 patients with panmyelosis leukemia were observed with transmission electron microscopy (TEM),scanning electron microscopy (SEM),myeloperoxidase (MPO) and platelet peroxidase (PPO).A lot of immature cells were found in the granulocytic, monocytic,erythrocytic and megakaryocytic series.Their major morphologic characteristics were as follows. In the erythrocytic series, petaloid-like and ball-like structure appeared and their perinuclear cisters were wider. In the myelomonocytic series, nuclear-cytoplasmic organelle asynchrony could be seen makedly and the nucleus appeared fully mature, but the cytoplasm contained only a few organelles, and in some cells the organells were often locally distributed. In the megakaryocytic series, many micromegakaryocytes were seen. In this paper, the ultrastructura] changes of four kinds of cells and their relationship with erythro-leukemia are also discussed.

Immunologic Classification of Acute Lymphocytic Leukemia: A Report of 19 Cases / 第二军医大学学报

Immunologic classification of acute lymphocytic leukemia (ALL) was carried out by using 11 - 13 kinds of monoclonal antibodies against human leucocyte differentiation antigens in 19 cases. The results showed that of these 19 cases, there were T-ALL in 4, B-ALL in 4, C-ALL in 7, AUL in 2 and hybrid type of ALL (H-ALL) in 2. The 5 types mentioned above could also be classified, according to the immunologic criteria described by Foon in 1986, into 3 major groups: T-ALL, non-T-ALL and H-ALL. The Foon's classification method is useful for judgement of malignant cell source and differentiated stage, and for further understanding the nature of ALL cells.
