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 explore the effects of dexamethasone on ovulation induction in polycystic ovary syndrome (PCOS).Methods This clinical study included 68 women with PCOS, which of them were divided into two groups: 34 in dexamethasone treating(dexamethasone combined with ovulation induction) and 34 in con-trol(ovulation induction treatment only).Subsequently, comparisons were made between pre and after drug treat-ment in two groups, the main indexes were the levels of testosterone(T), luteinizing hormone(LH), follicle stim-ulating hormone(FSH), growth rate of follicle, and body mass index(BMI).And we have also considered the o-vulation rate and pregnancy rate, and compared these indexes in dexamethasone treating group with control group.Results There were significant differences between pre and after dexamethasone treatment in the levels of T in treatment group(P < 0.01), and there were not significant differences between pre and after treatment in the lev-els of T in control group (P >0.05).LH had decreased significantly after treatment in both two groups (P <0.01), FSH had not significant differences between pre and after treatment in two groups(P >0.05).The growthrate of follicle of two groups had elevated after treatment (P < 0.01).And the ovulation rate in dexamethasone treating group was higher than that in control group(P < 0.05), but there were not significant differences between the two groups in the clinical pregnancy rates(P >0.05).There were not significant differences between pre and after treatment in the levels of BMI in both two groups (P > 0.05).Conclusions Dexamethasone can decrease the T in plasm levels.It is good for ovulation induction in PCOS.

OBJECTIVE To study the classification and distribution of the ?-lactamases produced by Escherichia coli in diabetic patients.METHODS To detect the ?-lactamases produced by E.coli in diabetic patients with a multi-disk synergy test.RESULTS Forty-nine strains of 60 strains in our study produced the ?-lactamases with total positive rate of 81.67%,From them 5 strains were producing penicillinases,17 strains producing BSBLs(28.33%),and 27 strains were producing ESBLs(45.00%),no carbapenem-hydrolyzing ?-lactamases were detected.In 27 strains producing ESBLs,the sensitivities to the ceftazidime,aztreonam and cefotaxime were similar.CONCLUSIONS The types of ?-lactamases produced by E.coli in diabetic patients are mainly BSBLs and ESBLs,without carbapenem-hydrolyzing ?-lactamases;the sensitivities to the ceftazidime,aztreonam and cefotaxime are similar.

According to the base complementation, the principle antisense technology is the sequence specific binding of complementary antisense nucleic acids or their chemical modification to the nucleic acids in cells, resulting in the suppression or prevention of gene translation. For the treatment of cancer, a lot of antisense drugs have been designed, which target the genes involved in the pathogenesis of cancer. And some of them have been in clinical trials. The author reviewed the progress of the clinical trials of these antisense drugs.

Objective To study the factors which affect the functional restoration of the elbow for adults with supracondylar or intercondylar fractures of the humerus treated with open reduction and internal fixation. Methods 22 patients with supracondylar or intercondylar fractures of the humerus were treated with open reduction and internal fixation from January, 1999 to December, 2004. They were followed up for an average of 30 months and complete clinical data were kept. The function of the elbow was evaluated with the Mayo elbow performance index. The relationship between the results and the factors —initial time of postoperative rehabilitation, fracture classification, operative approach and interval from injury to operation —were analyzed with cumulative logistic regression model of SAS software V8.2 (SAS institute, Cary, North Carolina). Results Of the 22 cases, 7 were excellent, 9 good, 5 fair and 1 poor. The excellent and good rates were 72.7%. And the odds ratio estimates of the 4 factors were 0.786, 0.299(B/A)0.221(C/A), 1.038, 0.197 respectively. Conclusions The initial time of postoperative rehabilitation, the fracture classification and the interval from injury to operation affect the functional restoration whereas the operative approach does not. Early operation, anatomical reduction, stable fixation and early rehabilitation will help improve the functional restoration.
