Eighty patients with hyperthyroidism treated in PLA 903 Hospital from February 2016 to May 2017 were randomly divided into two groups with 40 cases in each group.Patients in control group received routine outpatient education and those in study group received regular formatted mobile short message during follow-up in addition to routine education.The knowledge of disease,the compliance and satisfaction of treatment were assessed.After 12 weeks of follow-up,the TSH level was higher [0.430(0.050,2.806) vs.0.210(0.003,1.098) mU/L,Z=-8.07,P＜0.01],FT3 [(3.24± 1.18) vs.(4.18±2.07)ng/L,t=-2.49,P＜ 0.05] and FT4 levels [(12.43±6.82) vs.(19.58±19.06) ng/L,t=-2.26,P＜0.05] were lower in study group than those in control group.The scores of disease knowledge (6.12± 1.77 vs.5.25±1.79,t=4.67,P＜0.05),the Morisky scores of medication compliance (3.77±0.47 vs.3.37±0.73,t=8.22,P＜0.01),the rates of compliance for returning (85％ vs.65％,x2=4.27,P＜0.05) and the satisfaction rates with treatments (93％ vs.75％,x2=3.30,P＜0.05) in the study group were significantly higher than those in the control group.The score of disease knowledge in study group increased from 4.32± 1.55 before treatment to 6.12± 1.77 after 12 weeks of follow-up (t=22.65,P＜0.01).The results indicate that the health education plus regular formatted text message during follow-up can effectively improve the disease knowledge score,the compliance and satisfaction with treatment in patients with hyperthyroidism.

Objective To deduce carotid elasticity transmission index (CETI) and explore the correlation between CETI and intima-media thickness (IMT) of the carotid artery to investigate the clinical value of CETI. Methods Seventy-seven patients with essential hypertension (EH) and 24 healthy controls were collected. Their blood flow rate of cerebral arteries was detected by transcranial Doppler (TCD) and the pulsatility index (PI) was calculated. Their IMT and blood flow rate of common carotid artery (CCA) were detected by difunctional color Doppler; and then, their PI was calculated to analyze the correlation between CETI and IMT by curve fitting. The formulas were determined as: CETI1=PIMCA/PICCA, CETI2=PHCA/PICCA and CETB=PIBA/PICCA. Multiple stepwise regression analysis was employed to reflect the sensitive factors of IMT and CETI. Results Curvilinear correlation (curve of quadratic equation) was noted between CETI, including CETI1, CETI2 and CETI3, and IMT; each of the determination coefficient was r2=0.665, 0.601 and 0.573, respectively. Quadratic equations were y1=0.504+0.049x+0.203x2, r=0.815, P=0.000; y2= 1.009-1.141x+0.891x2, r=0.775, P= 0.000; y3=0.775-0.687x+0.641x2, 7=0.756, P=0.000. Among them, the correlation between CETI1 and IMT was the most significant. Linear regression was noted between IMT and LDL-C, daily dosage of smoking, SBP and gender. Linear regression was noted between CETT1 and both SBP and daily dosage of smoking. Linear regression was noted between CETI1 and both SBP and daily dosage of smoking. Linear regression was noted between CETI3 and SBP, CHOL and daily dosage of smoking. Conclusions CETI increases with the increase of IMT, suggesting that the rate of cerebral atherosclerosis is faster than the one of carotid in hypertensive patients when the elastic reserve of intracranial carotid artery and cerebral arteries decreases and the thickness of IMT increases to a certain extent. The risk factors of CETI are similar to IMT.

OBJECTIVETo survey the prevalence of HIV-1 drug resistance in patients newly diagnosed as HIV positive and who were younger than 25 years of age but had not received treatment with antiretroviral treatment (ART) in Hunan province.

METHODSSerum specimens of HIV infected individuals were collected and HIV-1 pol genetic mutations associated with drug resistance were identified with PCR and interpreted with Stanford HIV Drug Resistance Database.

RESULTSA total number of 69 patients whose HIV sequences were amplified successfully with 2 (2.9%) specimens appeared mutations associated with HIV-1 drug resistance in the reverse transcriptase region, including one as V75M and the other one as K103N and V181C. Data showed that the prevalence of drug resistance in Hunan was 2.9%.

CONCLUSIONThe first line regiments of national ART seemed still effective. Most of the AIDS patients did not need to be tested on drug resistance status before starting ART. However, it is important to start HIV drug resistance surveillance in no time.

OBJECTIVETo investigate the impact of the establishment of chest pain center (CPC) model based on the pre-hospital real-time tele-12-lead electrocardiogram on the door-to-balloon (D-to-B) time and short-term outcome after primary percutaneous coronary intervention (PPCI) of patients with ST-segment elevated myocardial infarction (STEMI).

METHODSA regular CPC was established with pre-hospital transmitted real-time 12-lead electrocardiogram system for pre-hospital diagnosis of STEMI and enabled the STEMI patients to bypass the emergency room and directly treated in the catheter lab to shorten the D-to-B time. The mean D-to-B time, the short-term outcome and medical costs were compared in PPCI patients before (93 cases, group A) and after (149 cases, group B) the establishment of CPC.

RESULTSAfter the establishment of CPC, the annual mean D-to-B time was significantly shortened [(127 ± 79) min in group A vs.(72 ± 23 )min in group B, P < 0.01], the shortest monthly mean D-to-B time was remarkably reduced in group B than in group A [(56 ± 11) min vs. (73 ± 14) min, P < 0.01]. The annual ratio of D-to-B below 90 minutes was significantly increased from 62.4% (58/93) in group A to 91.9% (137/149) in group B (P < 0.05) . The in-hospital mortality rate tended to be lower and the incidence of heart failure during hospitalization was significantly reduced in group B compared with group A [3.4% (5/149) vs. 6.5% (6/93), P > 0.05; 14.1% (21/149) vs. 24.7% (23/93), P < 0.05]. The length of hospital stay was slightly shortened from (8.98 ± 4.89) days to (7.79 ± 5.43) days (P > 0.05). Corrected mean medical cost went down by 9.4% (P < 0.05).

CONCLUSIONThe establishment of CPC may significantly shorten the D-to-B time, improve the short-term outcome and reduce the hospitalization cost for PPCI patients with STEMI.

OBJECTIVETo compare the immunophenotypic and clinical characteristics between NPM1 mutated acute myeloid leukemia (AML) (NPM1m(+)AML) and unmutated AML(NPM1m(-)AML) not otherwise characterized (NOS) under similar FAB subtypes constituent ratio.

METHODSImmunophenotyping and NPM1 gene mutation type-A, B and D and other leukemic related fusion genes were detected by multiparameter flow cytometry and real time RT-PCR or PCR, respectively. 104 AML patients with NPM1m(+)AML and performed immunophenotyping assay were included, 97 with NPM1m(-)AML.

RESULTSThere were significant difference between the two groups at presentation in terms of sex, white blood count(WBC), platelet counts (PLT), blast ratio, normal karyotype ratio, WT1 expression level, FLT3-ITD mutation positive rate and remission rate of first course of induction therapy (P < 0.05). On the immunophenotype, the expression of early differentiation antigens (CD34, HLA-DR, CD117, CD38), lymphocytic antigens (CD7, CD4, CD19, CD2), myeloid and monocytic differentiation-associated antigens (CD13, CD14, CD15) were lower, and that of CD33 as well as CD123 were higher in NPM1m(+)AML patients. Among them, only CD34, HLA-DR, CD7, and CD4 positive cases were significantly lower in NPM1m(+)AML group than in NPM1m(-)AML group (P < 0.05), the rest of them had significant difference in the number of positive cells (P < 0.05). Above features were further analyzed between the M1/M2 and M4/M5 subgroups. M1/M2 cases retained the women prominent and had a higher WT1 expression level (P < 0.05). The expression of monocytic differentiation-associated antigens including HLA-DR and lymphocytic antigens were higher and that of CD117 were lower in M4/M5 subtype (P < 0.05). Among them, the positive rates of HLA-DR, CD64, CD11b, CD10, CD15, and CD4 were significantly higher in M4/M5 than in M1/M2 in NPM1m(+)AML group (P < 0.05).

CONCLUSIONThe most clinical characteristics in NPM1m(+)AML patients are consistent with reports, but some immunophenotype are different to the previous reports under similar FAB subtypes constituent ratio. The major immunophenotypic features of NPM1m(+)AML patients are lower expression of progenitor, myeloid and lymphoid lineage antigens. Monocytic differentiation-associated antigens are only higher expression in M4/M5 cases when comparison with M1/M2 cases within NPM1m(+)AML group.

OBJECTIVETo study the rate of human immunodeficiency virus (HIV) seroconversion, HIV transmission and related risk factors among injecting drug users (IDUs) in an area of Sichuan province.

METHODSIn November 2002, a community-based baseline survey was conducted to recruit 333 HIV-seronegative IDUs for a prospective cohort study in Xichang county of Sichuan province, China. Follow-up visits were carried out every 6 months to study the situation of drug use, sexual behaviors of the IDUs and blood specimens were collected to test for antibodies against HIV and syphilis.

RESULTSDuring a 24-month follow-up period, cohort retention rate and HIV incidence were 75.7% and 2.53 per 100 person-years [95% confidence interval (CI): 1.10-3.97)], respectively. Multivariate Poisson regression model showed that risk factors which were significantly associated with HIV seroconversion would include: ethnicity (RR = 12.42; 95% CI: 2.72-56.74, P = 0.0012) and needle or syringe sharing in the past 3 months (RR = 4.06; 95% CI: 1.29-12.81, P = 0.0168). Syphilis seroconversion in this cohort was 4.71 per 100 person-years (95% CI: 2.59-6.82). In multivariate Poisson regression being female (RR = 4.42; 95% CI: 1.78-10.99, P = 0.0014) appeared to be the only factor which was significantly associated with syphilis seroconversion.

CONCLUSIONOur study results showed that there was a rapid transmission of HIV and syphilis among IDUs in Sichuan province, suggesting that effective intervention should be urgently taken.

This study was aimed to detect the expression level of cmtm 5 (CKLF-like MARVEL transmembrane domain containing member 5) gene in the bone marrow cells from patients with multiple myeloma (MM), and to investigate the correlation between the expression level of cmtm5 and various clinical characteristics. Real-time quantitative reverse transcription polymerase chain reaction (RQ-RT-PCR) was used to measure the expression levels of cmtm5 gene in the bone marrow cells collected from MM patients, and the MM cell lines, namely, RPMI8226 and CZ1 cells. The normal donor marrow specimens were used as the reference. The ratio of cmtm5 copy number to abl (Abelson murine leukemia viral oncogene homolog) gene copy number was used for indicating the expression level. The results showed that the expression level of cmtm5 gene was significantly down-regulated in bone marrow cells of 51 untreated or relapsed/refractory MM patient as compared to those of normal donor marrow cells (0.047+/-0.062 for the untreated or relapsed/refractory MM patients versus 0.255+/-0.333 for the normal, p<0.01). According to the International Staging System (ISS), the cmtm5 expression level in marrow cells of patients in ISS III stage was significantly lower than that in patients in ISS I stage (0.034+/-0.034 for the ISS III stage versus 0.103+/-0.109 for ISSI stage, p<0.01). Similarly, lower expression levels of cmtm5 gene were also found in two human MM cell lines (0.014+/-0.009 for RPMI8226 cells and 0.004+/-0.006 for CZ1 cells). After the MM patients were effectively treated, their expression levels of cmtm5 gene significantly increased (0.020+/-0.005 for the untreated patients versus 0.227+/-0.038 for the effectively treated patients, p<0.01). A significant negative correlation was observed between the expression level of cmtm5 gene and the number of bone marrow plasma cells (r=-0.307, p<0.05). However, the correlation was not found between the expression level of cmtm5 gene and the clinical characteristics, such as gender, age, hemoglobin level, or M-protein level, etc. It is concluded that the expression level of cmtm5 gene is abnormally lower in the bone marrow cells from the MM patients, and are associated with ISS stages. Furthermore, the expression level of cmtm5 gene is negatively correlated with the number of bone marrow abnormal plasma cells in MM patients, which suggests that the abnormally lower expression of cmtm5 may be involved in the pathogenesis of the MM patients.

OBJECTIVETo investigate the human immunodeficiency virus (HIV) and syphilis incidence rates as well as the retention rate in a cohort with 6-month follow-up study among female sex workers (FSWs).

METHODSFrom December, 2004, to January, 2005, a community-based baseline survey was conducted to recruit 343 FSWs for a prospective cohort study in Xichang county of Sichuan province, China. Follow-up visits were conducted at 6 months to analyze risk factors associated with cohort retention for subjects' baseline sociodemographic and sexual behavioral characteristics. Blood specimens were also collected to test antibodies against HIV and syphilis.

RESULTSDuring the 6-month follow-up period, HIV and syphilis incidence appeared to be 1.00 per 100 person-years and 6.23 per 100 person-years, respectively. The rate of retention in the cohort was 53.6% (184/343). Results from multivariate logistic regression model showed that factors were significantly associated with cohort retention including people with minority ethnic background (OR = 0.36; 95% CI: 0.18-0.74), people having participated in AIDS prevention program (OR = 1.83; 95% CI: 1.17-2.86) or being clients in the last 6 months > or = 50 (OR = 1.75; 95% CI: 1.11-2.77) and having changed living/working place (OR = 0.56; 95% CI: 0.33-0.94).

CONCLUSIONThe results of this study showed that the syphilis incidence and unprotected sex behavior were high among local FSWs. People belonged to Han nationality, having participated in AIDS prevention program and having a steady living/working place were associated with cohort retention at 6-month follow-up study among FSWs, respectively.

This study was purposed to compare the immunophenotypic and clinical characteristics of NPM1 mutated acute myeloid leukemia with a normal karyotype under the similar constituent ratio of FAB subtypes. Immunophenotyping and NPM1 gene mutation type-A,B and D and other leukemic related fusion genes were detected by multiparameter flow cytometry and real time RT-PCR or PCR, respectively. 77 AML patients with a normal karyotype (NK) and mutated NPM1 gene (NPM1m(+)AML) detected by immunophenotyping assay were included in this study. 55 cases without NPM1 mutation (NPM1m(-)AML) and with normal karyotype were served as negative control. The results showed that there was significant difference between NPM1m(+)AML and NPM1m(-)AML in terms of sex, white blood count, platelet counts, blast, WT1 expression level, FLT3-ITD mutation positive rate and response to treatment. The characteristic immunophenotype is lower expression of early differentiation-associated antigens (CD34, HLA-DR, CD117, CD38), lymphocytic antigens (CD7, CD4, CD19, CD2) and higher expression of CD33 and CD123 (P < 0.05). When above features was further analyzed between the M1/2 and M4/5 subgroups in NPM1m(+)AML patients, the M1/2 cases retained a higher frequency in women and a higher WT1 expression level (P < 0.05) . Monocytic differentiation-associated antigens including HLA-DR and lymphocytic antigens CD7 were higher expressed and CD117 was lower expressed in M4/5 subgroup (P < 0.05). It is concluded that under condition of similar constituent ratio of M1/2 and M4/5 subtype and normal karyotype, NPM1m(+)AML patients have higher WT1 expression level and better response to treatment. The major immunophenotype features of NPM1m(+)AML patients are lower expression of early differentiation antigens and lymphoid lineage antigens and higher expression of CD33 and CD123. Monocytic differentiation-associated antigens only higher are expressed in M4/5 cases when compared with M1/2 cases within NPM1m(+) AML patients.

Objective: To evaluate the effects of antiretrovirals on cardiovascular function and some biochemical indexes in gestational female rats. Methods: Nineteen 9-week-old female and six 10-week-old male SD rats were divided into normal control group (CON) and highly active antiretroviral therapy group (HARRT), 9/10 female rats and 3 male rats were combined into one cage, totally 2 cages. Female rats in CON group were intragastrically given with normal saline (NS, 10 ml/kg) every morning and evening, while female rats in HARRT group were treated with equal volume antiretrovirals (AZT 31.25 mg/kg + 3TC 15.63 mg/kg + LPV/r (41.67/10.42) mg/kg) for 3 months. The body weight and survival rate of female rats were recorded. Echocardiography and multichannel physiological recorder were used to detect arterial blood pressure and cardiac hemodynamic parameters. The levels of blood glucose, blood lipids, myocardial enzymes and liver enzymes were detected by corresponding kits. Myocardial collagen fibers were observed by Masson staining and the ultrastructure of myocardial cells were observed by transmission electron microscopy. Results: All female rats in CON group survived (9/9), while only 6 rats in HARRT group survived (6/10). Compared with CON group, the body weight of female rats in HAART group was decreased significantly(P＜0.01); the levels of left ventricular end diastolic diameter (LVDd), interventricular septal thickness (IVST), thickness of left ventricular posterior wall (LVPWT) , left atrial diameter (LAD) and arterial diastolic pressure were increased significantly (P＜0.05); the level of LVP+dP/dtmax was decreased (P＜0.01). The levels of triglyceride, creatine kinase, and glutamic oxaloacetic transaminase were decreased (P＜0.05 or P＜0.01), while the level of glucose was increased (P＜0.05). The collagen fibers were increased in myocardial tissue, and ultrastructure of myocardial cells was abnormal. Conclusion: Antiretrovirals during gestation can cause cardiovascular diseases in female rats.
