Iodine is an essential trace element for growth and development of fetus. More and more surveys currently show that the urinary iodine level of pregnant women is between 100 - 149 μg/L, which is lower than the level recommended by the World Health Organization (WHO). Under this level of iodine nutrition, different investigations have shown different effects on thyroid function of pregnant women, and the impact on growth and development of the fetus requires long-term objective evaluation. At present, there are three aspects: development, intelligence quotient (IQ), and psychological behavior. There are not many studies on comprehensive evaluation. This article combs the related published research to provide a reference for further clarifying the influence of iodine nutrition level during pregnancy on thyroid function of pregnant women and the growth and development of their offspring.

Objective To establish a HPLC method to determine the content of chlorogenic acid in Fructus Chaenomelis and its wine processing products.Methods Separation column was Agilent SB-C18(4.6mm?250mm,5?m) with the column temperature of 25℃.The mobile phase composition was methonal-1%HAc (80:20). The mobile speed was 1.0ml/min.The UV detection wavelength was 326 nm. Results A good linearity was obtained in the range of 5.47～71.14?g/ml,with r=0.9999. The average recovery was 101.98%,and RSD was 2.08% (n=6). Conclusion The content of chlorogenic acid was vary with the producing area of Fructus Chaenomelis.After wine processing,the content of chlorogenic acid was raised.The method was good for determining chlorogenic acid in Fructus Chaenomelis.

Objective To explore the feasibility of using unilateral continuous spinal anesthesia (CSA) in elderly patients undergoing hip replacement.Methods Forty-two ASA Ⅰ-Ⅲ patients (14 males, 28 females) aged 60-93yr were randomized to one of two groups: group 1 unilateral CSA (n = 21) and group 2 continuous epidural anesthesia (CEA,n = 21 ) . The patients in both groups were all premedicated with oral diazepam 5 mg and intramuscular scopolamine 0.3 mg. In group 1 unilateral CSA was performed at L2,3 or 3,4 interspace with the patients in the lateral position with the diseased leg upper most. The patients received a 27 gauge continuous spinal catheter, which was threaded through a 22 gauge spinal needle into subarachnoid space. Hypobaric 0-375% bupivacaine solution (0.75 % bupivacaine: sterile water = 1:1) 0.5-1.0ml was injected. If analgesia did not reach T10 after 5-10 min the same dose was repeated. In group 2 epidural catheter was placed also at L2.3or3,4. A test dose of 3 ml of 2% lidocaine was injected and then a mixture of 2% lidocaine and 0.5% bupivacaine (1:1) 8-10 ml was injected into the epidural space. The level of sensory block and degree of motor blockade were measured and recorded. The intraoperative and postoperative complications associated with spinal or epidural anesthesia were recorded. Results The demographic data, duration of operation and intraoperative blood loss were comparable between the two groups.In group 1 sensory block was confined to the diseased leg and no motor blockade of the healthy leg was observed. MAP was slightly decreased after initial dose of local anesthetics as compared to the baseline MAP in both groups. There was no significant change in SpO2 during operation in both groups. The incidences of hypotension, which needed treatment with intravenous ephedrine and shivering during operation and nausea and vomiting after operation were significantly lower in group 1 than in group 2. Conclusion Unilateral CSA produces satisfactory sensory block with stable hemodynamics and less complications and is anesthesia method of choice in elderly patients undergoing hip replacement.

Objective To explore the relationship of urinary iodine level between 8-10 year-old children and adults under the same living conditions in coastal and mountain areas in Fujian Province.Methods Representative coastal and mountainous rural areas (Xindian Town Xiang'an District Xiamen City and Yongfu Town Zhangping District Longyan City) were selected as survey sites.Morning fasting urine samples from local 8-10 year-old children and their parents and a random urine sample in the morning from these children were collected.Urinary iodine was determined using the arsenic cerium catalytic spectrophotometric method (WS/T 107-2006).Results The median urinary iodine of fasting urine samples which were collected from 147 8-10 year-old children in coastal rural areas (71 boys and 76 girls) was 163.5 μg/L (boys 161.0 μg/L,girls 170.9 μg/L),and the median urinary iodine of random urine samples was 190.8 μg/L (boys 208.7 μg/L,girls 177.0 μg/L),and the difference was not statistically significant between boys and girls (Z =-0.376,-0.678,all P ＞ 0.05).The median urinary iodine of fasting urine samples which were collected from 116 8-10 year-old children in mountain rural areas (66 boys and 50 girls) was 171.8 μg/L (boys 169.5 μg/L,girls 173.8 μg/L),and the median urinary iodine of random urine samples was 210.8 μg/L (boys 233.2 μg/L,girls 203.4 μg/L),and the difference was not statistically significant between boys and girls (Z =-0.413,-0.881,all P ＞ 0.05).The median urinary iodine of random urine samples which were collected from 8-10 year-old children in mountain rural areas was significantly higher than that of the morning fasting urine samples (Z =-2.789,P ＜ 0.05).The median urinary iodine of children's fathers in coastal rural areas was 177.0 μg/L,and the median urinary iodine of their mothers was 181.7 μg/L.There was no significant difference between coastal rural children and their parents (Z =-0.387,-0.658,all P ＞ 0.05),and there was also no significant difference between fathers and mothers (Z =-0.014,P ＞ 0.05).The median urinary iodine of children's fathers in mountain rural areas was 227.3 μg/L,and the median urinary iodine of their mothers was 237.4 μg/L There was a significant difference between mountain rural children and their parents (Z =-4.176,-4.373,all P ＜ 0.05),and there was no significant difference between fathers and mothers (Z =-0.291,P ＞ 0.05).Conclusions Urinary iodine level of school-age children does not reflect the actual urinary iodine level of adults.There is a difference between urinary iodine level of random urine sample and morning fasting urine sample.Attention should be paid to this difference when monitoring iodine nutrition in population.

Purpose:To study the characteristics of biological distribution in vivo and therapeutic efficacy of 125 I-anti-alpha-fetoprotein(AFP) antibody when administrated by the hepatic artery , and discussion of multi-modal therapy by transcatheter arterial chemoembolization(TACE) and immunization therapy. Methods:21 patients with moderately and advanced primary liver cancer (PLC) were treated by 125 I-anti -alpha-fetoprotein which was administered via hepatic artery, together with TACE and CD3AK cell by intravenous infusion to,detect the pharmacokinetic parameters and metabolism for 125 I-anti-AFP in vivo, and observe the efficacy of multi-modal treatment. Results:The radioactivity half-life time of ?phase (T 1/2 ?) and ? phase ( T 1/2 ?) for 125 I-anti-AFP antibodies was 1.85?1.79 and 156.46?65 hr,respectively; half-excretion time from urine was 94 hr, radiation intensity measured at body surface of organ suggested that the accumulated radioactivity was stronger and longer in the liver was than other organ.TPECT for tumour:liver ratio was 2.1?0.6. The efficacy for the treated group and the control group was respectively 61.9%(13/21) and 25.0%(5/20),the one-year cumulative survival rate of the treated group and the control group was also 61.9% and 25.0%.Conclusions: 125 I-anti-AFP via hepatic artery was able to concentrate electively in the tumour ,thereby bringing about a continuous internal irradiation for the tumour.This combined treatment is an effective method for PLC.

This study was designed to investigate whether there is an antagonistic effect of MsC—derived IL—1 and PGE2 on MsC proliferation. Experimental results showed that: (1)MsC stimulated by LPS could produce IL—1; (2) MsC stimulated by MsC—derived IL—1 could release PGE2; (3) exogenous PGE2(100ug/ml) inhibited the MsC proliferation induced by MsC—derived IL—1; (4) indomethacin(2ug/ml) which inhibited the production of endogenous PGE2, enhanced the MsC proliferation induced by MsC—derived IL—1. The results suggest that there is a self—regulation effect on MsC proliferation by MsC—derived IL—1 and PGE2. Clinically, the beneficial effect of PGE2 should be protected, so that the abuse of indomethacin in the treatment of glomerulonephritis should be avoided.

Objective To explore the influence of integrated Chinese and western medicine therapy on anxiety,sugar metabolism and subjective well-being for type 2 diabetes Patients associated with anxiety.Methods Use glycated hemoglobin (HbAlc),trait anxiety inventory(TAI),and Memorial University of Newfoundland Scale of Happiness (MUNSH) to evaluate the condition of 60 patients with type 2 diabetes associated with anxiety.The patients participated in the study were randomly divided into Western medicine therapy group(control group)and integrated traditional Chinese and Western medicine therapy group (experimental group),with 30 cases in each group.The control group was treated with paroxetine while the experimental group was treated with paroxetine plus Jiawei-Xiaoyaowan.6 weeks after treatment,we tested the HbAlc level.TAI score and MUNSH score of those patients.Results After 6 weeks,the TAI score of patients in both experimental group and control group have obviously decreased (before treatment:54.07±6.41 and 56.33 ±6.01,respectively; after treatment:38.89±6.70 and 45.29±6.55,respectively) and the difference was statistically significant (P＜0.05).And the TAI score of the two groups after treatment was significantly different (P＜0.05).For both experimental and control groups,the HbA1e level were not obviously changed before and after the study with P＞0.05 (before treatment:8.14±2.69 and 8.07±2.11,respectively; after treatment:8.21±2.07 and 7.92± 1.90,respectively).Comparison between groups also showed no significant difference.MUNSH score have obviously increased in experimental group (before treatment:40.49±5.22; after treatment:44.53 ± 6.28,P＜0.05).The result of comparison between the two groups after treatment shows that MUNSH score of patients in the experimental group were obviously improved compared with patients in the control group (57.56 ±6.39),and the difference was statistically significant (P＜0.05).Conclusion The integrated traditional Chinese and western medicine therapy can obviously release anxiety and enhance subjective well-being in patients with cerebral infarction associated with anxiety.

Objective To investigate the clinical features of primary Sj(o)gren syndrome (pSS) with interstitial lung disease (pSS-ILD) so as to raise the clinical diagnosis Level. Methods The clinical data were collected from 58 patients with pSS,who were admitted from March 2006 to March 2009. The patients were divided into ILD group (27 cases) and non-ILD group (31 cases). Rheumatoid factor(RF),C-reactive protein (CRP), protein electrophoresis and complement C3, C4 in serum were measured by immunoturbidimetric methods. Antinuclear antibodies (ANA) and anti-ENA antibodies were measured by indirect immunofluorescence technique and western blot. CA125 was detected by enzyme-linked immunosorbent assay and erythrocyte sedimentation rate (ESR) was detected by WS method. Pulmonaly function tests and radiology examination were performed. Results Compared with those in non-ILD group,the percentages of dry mouth,dry eye, rampant caries and velcro crackles were significantly higher in ILD group,anti-SSA antibody, ESR,CRP, CA125 and title of γ-gloulin was significantly higher in ILD group. In ILD group,diffusion dysfunction was 18 cases (66.7%),restricted ventilation dysfunction was 14 cases (51.9%),blocked ventilation dysfunction was 6 cases (22.2%), incorporated ventilation dysfunction was 8 cases(29.6%), forced vital capacity, forced expiratory volume in one second, maximum midexpiratory flow, DLCO were significantly lower in ILD group than those in non-ILD group (P ＜ 0.01). Moreover,high resolution computerized tomography (HRCT) was more sensitive than chest X-ray in the diagnosis of pSS-ILD.Conclusions The presence of pSS-ILD highly associates with the activity of pSS. Pulmonary diffusion ventilation function and HRCT play an important role in the diagnosis of pSS-ILD.
