Long-term excessive iodine intake resulted in an increased TT_4 level and a decreased TT_3 level in maternal serum,meanwhile,hepatic and renal type 1 deiodinase activity decreased dose-dependently.A significant reduction in type 2 deiodinase ( D2 ) activity of 12.5 d placenta was found in 3.0 mg/L or above groups.For 19.5 d uterus,D2 activity decreased and type 3 deiodinase activity increased.The results suggest that excessive iodine has an effect on the embryonic development by regulating maternal-fetal thyroid hormone metabolism.

Objective To explore the suitable way of batch cisplatin dissolution in pharmacy intravenous admixture service (PIVAS) and ensure the patients' receive medicine timely and accurately.Methods All samples were divided into control group and experiment group,with 200 cisplatinum in each group.The control group added dissolvent and then oscillated for 30 min,and the dissolve time of cisplatin was observed.The experiment group put the cisplantin into warm water after oscillation for 1 min.According to the water temperature,five subgroups were divided into five subgroups with each group 40 cisplantin:subgroup A (water temperature 46 ℃ ),subgroup B ( water temperature 48 ℃ ),subgroup C ( water temperature 50 ℃ ),subgroup D( water temperature 52 ℃ ) and subgroup E( water temperature 54 ℃ ).The state of cisplatin dissolve every one minute and dispensing time were recorded.Results Compared with the control group,the cisplatin in the experiment group was solved more completely,and the difference was statistically significant( x2 =9.087,P＜0.05).With the step-up of water temperature,the number of the dissolved cisplatin in 5 min of experimental subgroups gradually increased,subgroup A,9 cases (22.5％) ;subgroup B,28 cases (70％) ;subgroup C,34 cases (85％) ;subgroup D,40 cases ( 100％ ),and 33 cases in subgroup D,40 cases in subgroup E within 3 min.Conclusions In PIVAS 24-h continuous mode,the way of cisplatin dissolve by heat and oscillation for 1 min,with the water temperature keeps 52 ℃ and dissolve time in 5 min is a faster and effective method.This mode can save time and improve efficiency.

BACKGROUNDDifferential diagnosis of isolated calf muscle vein thrombosis (ICMVT) and gastrocnemius hematoma is essential for early identification of deep vein thrombosis (DVT). This study aimed to investigate the diagnostic value of high-frequency color Doppler ultrasound for differential diagnosis of ICMVT and gastrocnemius hematoma.

METHODSA retrospective case series of 35 ICMVT (M:F, 21:14; mean age (64.5 ± 10.6) years) and 23 gastrocnemius hematoma (M:F, 16:7; mean age (75.4 ± 11.8) years) patients with bilateral/unilateral lower limb pain was conducted between January 2006 and September 2012. Characteristics and the morphology of high-frequency color Doppler ultrasonography of the lower limb deep vein, great saphenous vein, calf muscles, skin, and soft tissue were examined.

RESULTSICMVT hypoechoic signals were characterized by long, tube-like masses on longitudinal sections and oval masses on transverse sections, with apparent muscle thrombosis boundaries, distal and proximal venous connections, and, often, lower limb DVT. Gastrocnemius hematoma hypoechoic signals were characterized by large volumes, enhanced posterior hematoma echo, hyperechoic muscle boundaries, no hematoma blood flow, and no DVT, and clear differences in trauma/exercise- and oral anticoagulant-induced hematomas were readily apparent. According to the measurement, the ratio of long diameter/transverse diameter (D/T) in ICMVT patients was about less than 2.0, whereas in gastrocnemius hematoma patients the ratio was more than 2.0. Early stage isoechoic and hypoechoic signals were detected with gradually increasing ovular anechoic areas. Partial muscle fibers in the hematoma due to muscle fractures were apparent.

CONCLUSIONHigh-frequency color Doppler ultrasound was found to be a sensitive and reliable method for differential diagnosis of ICMVT and gastrocnemius hematoma due to trauma and exercise or prolonged oral anticoagulant use.

OBJECTIVETo explore the therapeutic effect of interleukin-11 (IL-11) on high-dose methotrexate (HDMTX) induced mucositis in Wistar's rats, the proliferative effect on CEM leukemia cell line and the antitumor effect on HDMTX.

METHODSNinety-five 5-week old, 120 - 150 grams weight Wistar rats were randomly divided into five groups. Group A is normal control (n = 15), group B MTX control (n = 20), group C IL-11 pretreatment group before MTX injection (n = 20), group D (n = 20) the high dose IL-11 group (475 microg.kg(-1).d(-1)) after MTX injection, group E (n = 20) the low dose IL-11 group (150 microg.kg(-1).d(-1)) after MTX injection. All rats in group B approximately E were given 1 ml MTX intraperitoneally (100 mg/kg). Rats were killed at day 1, 3, 5, 7 after MTX injection. The mortality rates, changes of small intestine tissue morphology and ultra structure were observed. The proliferation of small intestine crypt cell was assayed by proliferating cell nuclear antigen (PCNA) immunohistochemical staining. MTT method was used to detect the proliferation of CEM cell line.

RESULTIL-11 treatment resulted in a significant increase of survival of HDMTX treated rats, increased of small intestinal villus length and villus/crypt ratio. IL-11 administration was associated with enhancement of small intestine mucosa recovery after HDMTX therapy. Group C showed a greater effect than group B (P < 0.01). IL-11 had no effect on CEM cell proliferation.

CONCLUSIONIL-11 has a significant mitigating effect on high-dose MTX induced intestinal mucositis in rat, and significantly increase the survival of the rats. IL-11 could be safely used in the HDMTX treatment of childhood acute lymphocyte leukemia.

OBJECTIVETo study the newborn's Apgar score in 'one minute' and relevant factors.

METHODSOne year inpatient woman from a Maternal and Child Health Hospital of Anhui province were selected by cluster sampling method and newborn asphyxia situation was investigated using Apgar score and self-designed questionnaire.

RESULTSThe Apgar score in 'one minute' which marking 8 to 10, 4 to 7 and 0 to 3 were found in 1875 (73.78%), 426 (16.77%) and 240 infants (9.45%) respectively. The average Apgar score in 'one minute' and five minutes were (7.69 +/- 2.27) and (9.01 +/- 1.89) respectively, The Apgar score in 'one minute' was significantly correlated with that of five minutes (Pearson coefficient correlation r = 0.841, P = 0.00). Ordinal regression analysis revealed that parturient age (OR = 1.04), being farmer (OR = 2.22), parity (OR = 1.26), assistant vaginal delivery (OR = 4.93), caesarean section (OR = 1.95), pregnancy-induced hypertension syndrome (OR = 1.42), albuminuria in gestational period (OR = 1.44), newborn being male (OR = 1.23), low birth weight (OR = 2.94), inborn abnormality (OR = 12.12), premature birth (OR = 1.22) and complications of delivery (OR = 5.04) were risk factors while the number of years under study (OR = 0.91), prenatal check-up (OR = 0.48), body length of newborn infant (OR = 0.88) and single birth (OR = 0.57) were protective factors.

CONCLUSIONApgar score in 'one minute' of newborn infant was affected by several factors as stated above. Health care program in earlier period toward community parturient should be strengthened in order to discover and control high risk factors of duration of pregnancy in earlier period.

OBJECTIVETo investigate the molecular mechanism of the effect of alcohol on insulin sensitivity.

METHODSFour groups of Wistar rats were used, i.e. control (C) group, and low (L), moderate (M) and high (H) alcohol group. Alcohol doses of each group were 0, 0.6, 1.8 and 3.0 ml.(kg.bw)(-1).day(-1). Each group was comprised of 10 male and 10 female rats. Alcohol was given to rats by gastric intubation. Thirteen weeks later, serum was collected for testing of fasting plasma glucose and insulin. HOMA-IR index of each group were calculated. Total muscle RNA was extracted using Trizol Reagent (Promega). The expression level of IRS-1 mRNA in muscle was detected by RT-PCR.

RESULTSIn female rats, the fasting plasma glucose of group (8.36 +/- 0.57) mmol/L was higher and the fasting plasma insulin (15.25 +/- 3.32) was lower than those of group C (7.56 +/- 0.85, 20.80 +/- 3.25). The HOMA-IR of group L (1.775 3 +/- 0.138 1) was lower than that of group C (1.982 6 +/- 0.124 6) (P < 0.05), while IRS-1 mRNA (0.766 1 +/- 0.076 9) was up-regulated (P < 0.05); HOMA-IR of group M (2.202 2 +/- 0.271 0) was higher than that of group C (P < 0.01), while IRS-1 mRNA (0.501 8 +/- 0.049 2) was suppressed (P < 0.01); HOMA-IR of group H (1.850 1 +/- 0.162 8) was not significantly changed as compared with that of group C (1.982 6 +/- 0.124 6) (P > 0.05), while IRS-1 mRNA (0.418 1 +/- 0.049 1) was significantly suppressed (P < 0.01). In male rats, the fasting plasma glucose and insulin had the similar change as those of female rats. The HOMA-IR of group M (1.878 5 +/- 0.250 2) was lower than that of C group (2.147 3 +/- 0.330 8) (P < 0.05), IRS-1 mRNA was up-regulated (0.824 9 +/- 0.064 7) (P < 0.05).

CONCLUSIONSThe present study showed that low-to-moderate dose of alcohol could increase insulin sensitivity; while alcohol abuse could decrease insulin sensitivity. Sex difference in this effect was found. Changes of IRS-1 mRNA expression may be involved in the molecular mechanism of the effects of alcohol on insulin sensitivity.

OBJECTIVETo study the effects of excess iodine intake on neurogranin expression in cerebrum of filial mice and the intervention of selenium.

METHODSSixty BALB/c mice were divided randomly into four groups with different drinking water: control group (tap water, NC), excess iodine group (3000 microg/L I, EL +), supplementing selenium group (200 microg/L Se, Se +) and the excess iodine plus selenium (3000 microg/L + I 200 microg/L Se, EI + Se +) group. The mice were mated at the end of the fourth month. Serum T4 and T3 were determined on postnatal day 14 and 28. The expression level of neurogranin in filial cerebrum was measured by immunohistochemistry and Western blot.

RESULTSSerum T4 level in EI (68.78 +/- 11.10 nmol/ L) + was lower significantly than that in NC (100.85 +/- 11.47 nmol/ L) and EI + Se + (93.15 +/- 12.10 nmol/ L) on postnatal day 14. Western blot analysis showed that the relative level of neurogranin in EI + (0.621 +/- 0.041) was lower than that in NC (0.841 +/- 0.039) and EI + Se + (0.781 +/- 0.029) on postnatal day 14 (P < 0.05). No significant difference in serum T4 and neurogranin level between four groups on postnatal day 28.

CONCLUSIONExcess iodine intake might change the expression of neurogranin in filial cerebrum and the selenium supplementation might alleviate it.
