Cytological characteristics of a case of adult T-cell leukemia were studied by detection of morphologic, cytochemical and immunological methods. The leukemic cells found in the peripheral blood belonged to mature T-lymphocytes and presented the changes of polymorphous nucleus which had diagnostic significance in association with clinical features and positive ATLA antibody. The mechanism of formation of cytological characteristics of adult T-cell leukemia is also discussed.

Inhibition of proliferation and induction of differentiation by 1, 25-dihydroxyvitamm D3 of human promyelocytic leukemic cell line (HL-60)are reported. At the concentration range of 109 to 106 mol/ L, 1, 25-dihydroxyvitamin D3 had effect in inhibiting cell proliferation with time-dependent and dose-dependent manner. Strong inhibition of colony cell growth (74.8?11.1%)was observed at 107 mol/L concentration. It was also found that HL-60 cells could be induced into monocytes by 1, 25-dihydroxyvitamin D3at the same concentrations,which were demonstrated by cytochemistry and specific antigen of cell surface and NBT reduction test. In addition, the relationship between proliferation and differentiation is discussed according to the result of flow cytometry.

Objective To explore the relationship of T2DM with xerophthalmia after cataract surgery.Methods Retrospective analysis was made on the clinical data of 137 cataract patients (176 eyes) from April,2016 to October,2016.The DM patients were chosen as the DM group (58 cases,71 eyes),and single cataract ones were chosen as the control group (79 cases,105 eyes).The clinical data and xerophthalmia index were compared between two groups.Results The age and sex constituent ratio of DM group and control group had no significant difference (all P ＞ 0.05).The postoperative MQ score,BUT,FL,SⅠt of DM group at 1 week,1 month and 3 months were significantly worse than those at preoperative 2 days (all P ＜ 0.01),but the indexes relieved with time prolong.The postoperative MQ score,FL,SⅠt of control group at 1 week,1 month were significantly worse than those at preoperative 2 days (P ＜ 0.01),the postoperative BUT and preoperative BUT had no significant difference (P ＞ 0.05),all of the postoperative index and preoperative index had no significant difference(all P ＞ 0.05).The postoperative MQ score,BUT,FL,SⅠt of DM group at 1 week,1 month and 3 months were significantly worse than those of the control group (all P ＜ 0.01).Conclusion The xerophthalmia after cataract surgery of T2DM patients are more seriously than normal cataract patients.

Objective To investigate the clinical advantages and safety profile of the combinational treatment of acute progressive cerebral infarction with aspirin,clopedogrel and atorvastatin.Methods 170 cases with acute progressive cerebral infarction were randomly divided into the treatment group and control group,85 patients in each group.Both two groups were initially treated with aspirin and atorvastatin.After excluding the possibility of hemorrhage, the treatment group additionally received clopedogrel,while the control group was treated with aspirin and atorvastatin. The difference in clinical efficacy was evaluated between before treatment and 7 days,14 days or 28 days after treatment by using the NIH Stroke Scale (NIHSS)and Barthel Index (BI).Results The NIHSS scores of the treatment group after 7d,14d and 28d were (12.52 ±3.25)points,(9.10 ±3.21)points and (6.87 ±2.85)points, which of the control group were (13.65 ±2.93)points,(10.73 ±3.41)points and (9.07 ±2.96)points respectively, the differences between the two groups were statistically significant(t =2.340,3.170,4.877,all P <0.05).The BI scores of the treatment group after 7d,14d and 28d were (35.26 ±11.18),(53.73 ±13.74)and (74.61 ±17.35), which of the control group were (31.98 ±9.12),(46.65 ±11.79 )and (63.87 ±15.73 )respectively,the differences between the two groups were statistically significant(t =2.131,3.752,4.456,all P <0.05).The overall effective rates of the treatment group after 7d,14d and 28d were 62.7%,79.5% and 94.0%,which of the control group were 51.2%,68.3% and 84.1% respectively.The differences of overall effective rates were statistically significant after 14d and 28d(χ2 =4.711,8.531,all P <0.05).Few reverse reactions were observed in both two groups.Conclusion Compared with the aspirin and atorvastatin therapy,combinational treatment of acute progressive cerebral infarction together with clopedogrel has a better efficacy,safety profile and significant promotion on neurological recovery.

Objective:The one-way communication between traditional LIS system and equipment has been unable to meet the needs of business development of medical laboratory in our hospital, we need to upgrade our equipment and to develop the bidirectional communication interface between LIS and equipment.Methods: Our hospital has invested a lot of money to upgrade previous One-way communication interface based on ASTM, the new instrument specifications conform to HL7 standard, and develop bidirectional transmission program based on HL7.Results: After the implementation of the bidirectional communication, testing equipment can automatically identify bar code to get the test request information, after the completion of the test instrument, the inspection unit can automatically send sample results to LIS.Conclusion: Bidirectional transmission improves the work efficiency, transmission based on HL7 is not only fast, but also conducive to the sharing of data between heterogeneous medical information systems, and it is a general tendency.

Diabetes mellitus is a common disease of serious harmful to human health,but its pathogenesis is not entirely clear.Mitochondria are the important organelles to generate energy in eukaryocytes,and play a pivotal role in the regulation of reactive oxygen species generation,intracellular calcium homeostasis,and apoptosis signal transduction.The possible causes of mitochondrial dysfunction include oxidative stress,Ca2+ disturbances,reduction of mitochondrial biosynthesis,opening of mitochondrial permeability transition pore,mitochondrial DNA mutations,and etc..Many studies demonstrate that mitochondrial dysfunction is associated with β-cell dysfunction of type 1 diabetes mellitus and insulin resistance of type 2 diabetes mellitus.Moreover,mitochondrial dysfunction plays important roles in the development of diabetic cardiomyopathy.This present article reviewed the current status of studies on the relationship of mitochondrial dysfunction and diabetes mellitus and diabetic cardiomyopathy.It is very important to understand and study mitochondrial dysfunction and its important roles in diabetes mellitus and diabetic cardiomyopathy in order to clarify the pathogenesis of diabetes mellitus and explore new approaches of prevention and treatment for diabetes mellitus.

Objective To study treatment method that improve the cronic perapical periodonitis. Methods To fill the tooth channal of chronic perapical periodonitis with a paste of doxycycline and tinidazol, or gutta percha point. Results Among 206 cases of teeth those succeesful rates of two methods were 97.09 % and 98.06 % after 2 years clinical observe. Conclusion To fill the tooth channal of cronic perapical periodonitis with a paste of doxycycline and tinidazol to treat the chronic perapical periodonitis,it shortens the treatment,simplifies operation,makes application more extensive and its nearly period effect is the same as that of using gutta percha point to fill the tooth.

Müller cells, as the special radial glial cells in the retina, span the entire retina, contact with neurons, microvessels and processes in the retina and play a significant role in protecting retinal structure and function.Diabetic retinopathy (DR) is a major ocular complication of diabetic patients.In the progression of DR, diabetic macular edema (DME) is the main cause of vision loss.During the occurrence of DME, the morphological and structural changes of Müller cells including severer swelling and vacuolation of cell bodies, increased apoptosis, and abnormal secretion of cytokines, etc.damage the blood-retinal barrier (BRB), increase the permeability of BRB and accelerate the exudation of subretinal fluid.In addition, Müller cells can disrupt the regulation of K + and water transportation, obstruct the fluid absorption in the subretinal space and promote the formation of DME.However, in the early stage of DR, neurotrophic factors secreted by Müller cells can protect the retina by alleviating retinal edema and protecting optic ganglion cells, suggesting that Müller cells can be used as targets for DME treatment.Therefore, new strategies can be provided by fully exploring the role and mechanism of Müller cells in the formation of DME.In this paper, the mechanism of Müller cells in DME and its protective role in the progression of DME were reviewed.
