Objective To investigate the dangers of heart failure to the mother and fetal,and the diagnosis and treatment of pregnancy complicated with heart failure. Methods The clinical data of the causes,timing,management and outcomes of 87 cases of pregnant women complicated with heart failure from March 1993 to January 2006 were analyzed retrospectively. Results ①Thirty-one cases(35.6%) of heart failure in pregnancy were caused by rheumatic heart disease,26(29.9%) by pregnancy-induced hypertension(PIH),16(18.4%) by congenital heart disease,and 14(16.1%) by peripartum cardiomyopathy.②The heart failure appeared at the average of(32.69?5.57) weeks.③The average terminal time of pregnancy was(34.66?4.52) weeks.④There were 79 newborns with 6 cases of twins,and the perinatal mortality was 8.6%(8 cases).Hysterotomy was performed in 6 cases in mid-pregnancy.The average weight of babies was(2419.56?786.08) g.⑤The maternal mortality was 6.9%(6 cases).(Conclusion The main) causes of heart failure in pregnancy are rheumatic heart disease,PIH and congenital heart disease.Although the standard management of pregnancy complicated with heart failure is inotropic agents,diurectics and vasodilators,the treatment should be individualized according to the specific etiology and with the consideration of the safety of fetus as well.Pinpointing the causes of heart failure in pregnant patients and treating accordingly may be conducive to reduce the maternal and perinatal mortality.

AIM: To investigate the clinicopathological features of orbit primary liposarcoma. METHODS: By means of histological, ultrastructural and immunohistochemical studies, the clinical and pathological features of two cases of orbit primary liposarcoma were analyzed and compared with 6 cases of primary retroperitoneum liposarcoma. RESULTS: Two cases of orbit primary liposarcoma were young persons. The majority of cases of primary retroperitoneum liposarcoma were aged over 40 years. The tumors were located at the retrobulbar region, and involved the wall of eyeball and optic nerve. The tumor cells of case 1 were round, with abundant eosinophilic granules in the cytoplasm, and there were lipoblasts in the tumor cells of two cases. Local recurrence following excision occurred in case 2.Immunohistochemical expression of S100 protein was positive in all cases, and CK (AE1/AE3), desmin, MyoD1, melanoma were negative. Ultrastructure observation showed lipid drops in the tumor cells in case 2 of orbit primary liposarcoma. CONCLUSION: Primary liposarcoma of the orbit may recur.The diagnosis was based on histological,ultrastruc-tural observation and immunohistochemical staining.

Methods In this is a cross-section study from September in 2008 to April in 2009,the observation group was historical iodine deficiency ward which includes 2 counties and 6 townships,and the control group was non-historical ward which includes 6 counties and 9 townships. Comparison of child IQ distribution according to different geographical housing position(plain,mountainous area,coast),age and sex based on the result of urine iodine examination and the IQ test of children between 8 and 10 years old. Results The median of urinary iodine of children in the observation group was 196.2μg/L which was 2.13 times of the urinary iodine median in the control group(91.9μg/L). The average IQ of children in the observation group was 94.7 which was 8.5 higher than the control group(86.2) ; IQ≤69 rate in this group was 7.7%(91/1179),and it was 8.9 percentage point lower than the control group[16.6%(253/1520)]; IQ≥ 110 rate of the group was 18.3%(216/1179),and it was 10.0 percentage point higher than the control group[8.3%(126/1520)]. The average IQ of children living in mountainous area(83.1) was the lowest in the control group. It was 3.5 and 5.1 lower than that of the children living in the plain(86.6) and coastal area(88.2) respectively; the IQ≤69 rate of children living in mountainous area [20.5%(91/443)]was the highest,and it was 3.8 and 7.1 percentage point higher than that of the children living in the plain [16.7% (89/533)]and coastal areas [13.4% (73/544)]respectively. The average IQ of children aged 8 (97.4) was similar to those aged 9(95.9) in the observation group which was 6.8 and 5.3 higher than that of the children aged 10(90.6) in the same group respectively; However,the average IQ of children aged 8,9 and 10 was close in the control group(86.8,86.3 and 85.6). The average IQ of boys(96.2) was 3.1 higher than that of the girls(93.1),and their IQ≤69 rate[6.3%(37/590)]was 2.9 percentage point lower than that of the girls[9.2% (54/589)]in the observation group. On the other hand,the average IQ(87.2) of boys was 2.1 higher than that of the girls(85.1),and IQ≤69 rate[14.5%(114/787)]was 4.5 percentage point lower than that of the girls [19.0%(139/733)]in the control group. The average IQ of children with different housing geographical position,age and sex in observation group was 5.0-12.4 higher than that of the control group; their IQ≤69 rate was 7.7-13.2 percentage point lower than that of the control group; their IQ≥110 rate was 5.6-13.0 percentage point higher than that of the control group. Conclusions Supplementing salt iodization can improve child intelligence. Supplementing iodine can increase the child IQ and reduce the child mental retardation.

Objective To know the prevalence of iodine deficiency disorders(IDD) and the implementation of control measures against the disorders in high-risk areas of Hainan province. Methods Typical sampling principle was used. Eight townships with lower coverage rate of iodized salt were chosen in IDD high-risk counties of Hainan. New cretinism cases were screened among children aged 10 years and under. Intelligence quotient (IQ)value, urinary iodine (UI) concentration and thyroid gland size (by palpation and B ultrasonic) were investigated in children aged 8 to 10 years and questionnaire was also carried out among students from grade 5 in elementary school. Edible salt and urine of women of childbearing age were collected to detect iodine levels, respectively,questionnaire was also carried out among the women of childbearing age. The UI was determined by As3-Ce4+ catalytic spectrophotometer, the salt iodine level was determined using self-quantitative kit. IQ values were measured by the Combined Raven Test in China (CRT-C2). Results Seventy-two townships were investigated in three consecutive years, 7937 children aged 8 to 10 years, 1797 women of childbearing age and 4128 students of grade 5 were included in the survey. One child was diagnosed as suspected new cretinism case. The coverage rate of iodized salt was increased from 44.6%(629/1411) in 2007 to 92.1%(1688/1832) in 2009. The goiter rate was dropped from 5.9% (269/4548), 6.0% (274/4548) in 2007 to 1.6% (24/1461), 0.1% (2/1461) in 2009 bypalpation, and by B-ultrasound, respectively, in children aged 8 to 10 years. The median urinary iodine(MUI) was found to be increased from 97.4 μg/L in 2007 to 165.0 μg/L in 2009, and the percentage of UI less than 50.0 μg/L, and 100.0 μg/L were dropped from 21.4%(973/4548), 51.2%(2329/4548) in 2007 to 7.5 %(110/1461), 23.4%(342/1461) in 2009, respectively. The MUI of women of childbearing age was found to be elevated from 73.7 μg/L in 2007 to 126.1 μg/L in 2009, and the value was also increased from 55.7 μg/L to 121.5 μg/L in pregnant women, but these values were still lower than 150.0 μg/L The pass rate of the questionnaire of IDD controlling among the students of grade 5 and the women of childbearing age was raised from 29.8% (446/1495) ,24.1% (179/742) in 2007 to 65.8%(732/1112), 72.1%(264/366) in 2009, respectively. The mean IQ of children was 90.4±16.0, and the percentage of IQ value less than 69 was 12.6% (1000/7937). Conclusions The diseased state of IDD has improved in the high-risk counties of disorders in Hainan province, but the pregnant women are still iodine deficient. Iodine supplimentation should be promoted among pregnant women.

OBJECTIVETo study the diagnostic accuracy of hematolymphoid malignancy by using effusion fluid cytology specimens and to evaluate the values of immunocytochemistry for this assay.
METHODSThe cytospin preparations/smears and cell block sections of effusion cytology specimens from 33 cases of hematolymphoid malignancy were retrospectively reviewed. Immunocytochemical study was performed. In selected cases, in-situ hybridization for Epstein-Barr virus-encoded RNA and immunoglobulin and T-cell receptor gene rearrangement study were carried out as indicated.
RESULTSThere were 33 cases of hematolymphoid malignancy, including 12 cases of T-lymphoblastic leukemia/lymphoma, 16 cases of mature B cell neoplasm (including 9 cases of diffuse large B-cell lymphoma, 2 cases of Burkitt lymphoma, 2 cases of plasmacytoma/multiple myeloma, 2 cases of B-small lymphocytic leukemia/lymphoma and 1 case of mantle cell lymphoma), 3 cases of mature T or NK-cell neoplasm (including 1 case of extranodal nasal NK/T-cell lymphoma, 1 case of angioimmunoblastic T-cell lymphoma and 1 case of T-cell prolymphocytic leukemia), 1 case of myeloid sarcoma and 1 case of mast cell sarcoma. Amongst the 33 cases studied, 16 represented disease relapses, including 8 cases of diffuse large B-cell lymphoma, 2 cases of plasmacytoma/multiple myeloma, 2 cases of B-small lymphocytic leukemia/lymphoma, 1 case of T-lymphoblastic leukemia/lymphoma, 1 case of angioimmunoblastic T-cell lymphoma, 1 case of mantle cell lymphoma and 1 case of mast cell sarcoma. The remaining 17 cases showed serous effusion as the primary manifestation, with the diagnosis primarily made upon cytologic examination. The cytologic findings seen in all the 33 cases studied were in agreement with the corresponding histologic diagnosis.
CONCLUSIONSDiagnosis of hematolymphoid malignancy by effusion fluid cytology specimens is possible, especially when coupled with the clinical history, immunophenotype, in-situ hybridization and gene rearrangement study findings. This is especially so for cases with disease relapses.
