Objective To find out the situation of household consumption of iodized salt in Hebei province so as to provide scientific basis for prevention and control of iodine deficiency disorders(IDD). Methods According to the "national iodine deficiency disorders surveillance program (Trial)", the county (city, district) was taken as a unit, township (town) and administrative villages were selected in accordance with the principle of systematic sampling, then households were chosen by random sampling to collect their edible salt in Hebei province from 2007 to 2009. Salt iodine content was detected by direct titration method. Results A total of 48 675, 48 448 and 48 756 salt samples were collected from 2007 to 2009, respectively. The consumption rate of qualified iodized salt from 2007 to 2009 was 91.16%, 91.96% and 96.17%, respectively. There were 24.6%(41/167)and 18.0%(30/167)counties with consumption rate of qualified iodized salt under 90% in 2007 and 2008, respectively. The percentage of counties with consumption rate of qualified iodized salt above 90% was 100.0%(167/167) in 2009. In general there was a significant differences in frequency distribution of consumption rates of qualified iodized salt among the three years(H = 10.778, P ＜ 0.01 ), and the difference was found significant between 2007 and 2009 as well as between 2008 and 2009(all P ＜ 0.05), but was not significant between 2007 and 2008(P ＞ 0.05). Conclusions The consumption rate of qualified iodized salt at household level increases annually from 2007 to 2009. By 2009,the consumption rate of qualified iodized salt in each county is more than 90%, which has reached the national standard stipulated in "the evaluation programs for fulfilling the goal of eliminating IDD at county level".

OBJECTIVE: To optimize the extraction technology of Bushen yangxue granules, and to provide reference for developing hospital preparations. METHODS: The orthogonal test was designed to optimize the extraction technology of Bushen yangxue granules using the comprehensive score including the content of hyperoside and total flavonoids, extract yield as evaluation indexes, water amount, extraction time and extraction times as factors. Verification test was also conducted. RESULTS: The extraction technology of Bushen yangxue granules was 10-fold water, extracting for 2 times and 1 hour each time. The results of verification test indicated that the contents of hyperoside and total flavonoids were 0. 154 mg/g (RSD=0. 010％, n=3) and 11. 094 mg/g (RSD=0. 008％, n=3). The average extract yield was 37. 76％ (RSD=0. 008％, n=3). CONCLUSIONS: The optimized extraction technology is stable and feasible, which can provide the basis for developing hospital preparations of Bushen yangxue granules.

The aim of the present study is to explore the mechanism of estrogen on regulating cardiac function disorder by adjusting the stimulating adenylate cyclase G α protein (Gαs)-cycle adenosine monophosphate (cAMP) signal pathway. Adult female rats were randomly divided into five groups: sham group, ovariectomized group (OVX), OVX and 17β-estradiol given group (OVX+E₂), OVX and isoprenaline injected group (OVX+ISO), OVX and 17β-estradiol, isoprenaline injected group (OVX+E₂+ISO). Rats were ovariectomized, and two weeks later, OVX+E₂group was injected with E₂, OVX+ISO group was injected with ISO, OVX+E₂+ISO group was injected with E₂and ISO. Another four weeks later, the hemodynamic parameters were monitored by carotid artery intubation: left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), maximal differentials of left ventricular developed pressure (+dp/dt(max)), and minimal differentials of left ventricular developed pressure (-dp/dt(max)). Brain natriuretic peptide (BNP) and cAMP concentration in plasma were determined; Gα(s) protein expression in myocardium was determined. The results showed that the hemodynamic parameters, the concentration of BNP and cAMP in plasma had no significant changes after ovariectomy compared with sham group. But after isoprenaline injection in ovariectomized rats, LVSP and +dp/dt(max) declined (P < 0.01), LVEDP and -dp/dt(max) elevated (P < 0.01); plasma BNP concentration increased (P < 0.01); plasma cAMP concentration decreased (P < 0.01), compared with OVX group. Further estrogen supplements improved the heart function treated by isoprenaline: LVSP and +dp/dt(max) elevated (P < 0.01), LVEDP and -dp/dtmax declined (P < 0.05, P < 0.01); the plasma BNP concentration decreased (P < 0.01); the plasma cAMP concentration increased (P < 0.01). Estrogen had no significant influence on Gαs protein expression. The results suggest that estrogen can alleviate myocardial injury and regulate cardiac function disorder by increasing cAMP level, finally improved the excessive suppression of myocardium.

OBJECTIVETo probe into the occurrence rates of the effective antigen combinations which were used to detect the minimal residual disease (MRD) by flow cytometry in childhood B-lineage acute lymphoblastic leukemia (B-ALL), as well as the relationship between clinical-biologic factors and different combinations.

METHODSAmong the 327 B-ALL children enrolled in our study, 289 cases were identified with at least one antigen combination as MRD marker. Their bone marrow samples were monitored by using 9 combinations with 4 antigens each, analyzed the occurrence rates and compared them with international reports. Also the differences in the distribution of each antibody combination in the different clinical-biologic groups were compared by the chi-square test and Fisher's exact test.

RESULTS(1) Totally 327 cases of childhood B-ALL were screened for antibody combinations of interest and 88.4 percent of them (289 cases) were identified with effective antibody combinations. (2) The occurrence frequencies of antigen combinations were different. The highest frequency was seen with TdT/CD10/CD34/CD19 combination which was 70.59 percent. Expressions of antigen combinations in Chinese children were different from those in western countries. (3) Some antibody combinations presented different frequency among different clinical groups. CD38/CD10/CD34/CD19 was expressed more often in samples of relapsed patients (P = 0.045). CD66c/CD10/CD34/CD19 expression was significantly higher in BCR/ABL positive group (P = 0.037) and relapsed patients group (P = 0.047). TdT/CD10/CD34/CD19 was expressed more in MLL-AF4 negative group (P = 0.005) and Prednisone Good Response group (P = 0.002). CD58/CD10/CD34/CD19 was correlated with low relapse rate (P = 0.032).

CONCLUSION(1) The coverage rate of 9 antigen combinations in our study was 88.4%. The occurrences of frequency of different antibody combinations in B-ALL were different, and also different from that of western countries. The occurrence frequencies of antibody combinations CD21/CD10/CD34/CD19, CD22/CD10/CD34/CD19, CD10/CD56/CD34/-CD19 and TdT/Cu/CD34/CD19 were lower than those of the western report, while CD38/CD10/-CD34/CD19, CD45/CD19/CD10/CD34, CD58/CD10/CD34/CD19 and CD66c/CD10/CD34/CD19 were similar to those of the reports from western countries. (2) TdT/CD10/CD34/CD19 may work as a simplified method to detect MRD in Chinese population. (3) The occurrence frequency of CD38/CD10/CD34/CD19, CD45/CD19/CD10/CD34, CD58/CD10/CD34/CD19, TdT/CD10/CD34/CD19 could be effective remediation and evidence to evaluate the remission quality and guide the therapy, especially for those with no original MRD marker record. (4) CD58/CD10/CD34/CD19 and TdT/CD10/CD34/CD19 may correlate with good prognosis, but CD66c/CD10/CD34/CD19 and CD38/CD10/CD34/CD19 may predict poor prognosis. These results might contribute to individual risk evaluation and guide the therapy selection.

OBJECTIVETo investigate the value of the HCT-CI score in chemotherapy risk assessment and prognosis of elderly patients with acute myeloid leukemia (AML).

METHODSThe clinical data of 116 AML patients older than 60 years in the department of Hematology, Henan Provincial People's Hospital from January 2000 to December 2010 were analyzed retrospectively. All patients received cytarabine-based regimens, including protocol DA, MA, IA, AA or CAG, followed by cytarabine-based postremission treatment. (1) Comorbidities were evaluated by using HCT-CI score, the early death rates and median survival time were compared among these different groups. (2) These prognostic factors were analyzed by univariate and multivariate analyses.

RESULTS(1) All 116 cases were followed-up. The patient cohort was divided into those with HCT-CI scores of 0, 1 or 2, or ≥ 3. Early death rates were 3.7%, 12.1% and 23.21% in above three groups, respectively (P < 0.01). Overall survival were 345, 225 and 113 days, respectively (P < 0.01). (2) HCT-CI score ≥ 3 (P < 0.01), antecedent MDS history (P = 0.035), high-risk karyotype (P = 0.018), white blood cells at diagnosis ≥ 100×10(9)/L (P = 0.041) were independent adverse prognostic factors with multivariate analysis.

CONCLUSION(1) The HCT-CI score can objectively assess elderly AML patients with comorbidities and predict chemotherapy risk in older patients receiving AML induction therapy. (2) Antecedent MDS history, high-risk karyotype, high white blood cell, and HCT-CI score ≥ 3 are independent adverse prognostic factors of elderly AML patients.

Objective: To explore the clinical characteristics and prognostic factors of the patients with non-Hodgkin's Lymphoma (NHL) complicated with HBV infection, so as to provide a basis for clinical accurate diagnosis and prognosis evaluation. Methods: The data of 313 newly diagnosed NHL patients from August 2012 to July 2016 were collected. The HBV serological markers were detected by ELISA, and HBV DNA was quantified by full automatic microparticle chemiluminescence immunoassay (≥1×10(5) copies/ml as high copy group, 1×10(3)-<1×10(5) copies/ml as low copy group). The relationship between HBV infection and prognosis was analyzed combined with the clinical features of the patients, and the HBV detection rate was compared with that of the common population (from the national HBV sero epidemiological data). Results: ①The positive rate of HBsAg in NHL patients was 12.5% (39/313), which was higher than 7.2% in the general population (χ(2)=14.596, P<0.001). HBV infection in the past (HBsAg negative but HBcAb positive) in 114 cases (36.4%), the incidence was slightly higher than that in the general population (34.1%). ②Compared HBsAg positive group with the negative group, the proportion of B cell type (87.2% vs 70.3%, P=0.027), Ann Arbor stage Ⅲ-Ⅳ(69.2% vs 34.6%, P<0.001), IPI score 3-5 (74.4% vs 50%, P=0.004), LDH level (79.5% vs 47.8%, P<0.001) and liver involvement (45.5% vs 31.7%, P=0.006) were all higher. The difference was statistically significant. ③Compared the HBV infected group (114 cases) with the non-infected group (160 cases), the difference had statistical significance in the proportion of Ann Arbor stage Ⅲ-Ⅳ (P=0.023) and IPI score 3-5 scores P=0.035). ④Compared HBV DNA positive group (30 cases) with negative group (71 cases), Ann Arbor stage Ⅲ-Ⅳ (P=0.011), IPI score 3-5 score (P=0.030), LDH level (P=0.025) and liver involvement (P<0.001) in the proportion of patients had statistical significance. The positive patients were divided into HBV DNA high and low copy groups with 1×10(5) copies of /ml as the boundary. The results showed that there was no statistical difference between the two groups (P>0.05). Conclusions: The HBV infection rate of NHL patients is significantly higher than that of the general population, and HBV infection is more closely related to B cell type NHL. Patients with HBV infection and HBV DNA positive had late Ann Arbor stage, high IPI score, high LDH level and liver involvement, and the prognosis is poor.
