Objective To understand the current situation of iodine deficient disorder(IDD) 10 years after achieving the stage goal of eliminating IDD in Longyan city and to evaluate the effect of prevention and treatment measures, and to provide the basis for the development of control strategies. Methods There were 7 counties in the city, and each county(city, district) was as a unit to carry out the inspection for organization and leadership,iodine salt management, monitoring and control, health education (referred to as the four management indicators)according to "The County-Level Assessment and Evaluation Implementation Detailed Rules of Realizing the Goal to Eliminate IDD in Fujian Province". According to the east, west, south, north and middle positions in each county,a village and a primary school were selected. Forty 8 to 10 year-old students in each school were randomly selected to check thyroid and among them 20 students were collected urine samples to determine urinary iodine. Nine townships were selected in the 7 counties of the city and among which 4 administrative villages were selected in each township. Eight edible salt samples from each household in each administrative village were collected to test salt iodine. Goiter was examined by palpation, the level of urinary iodine was examined by arsenic and cerium spectrophotometry, salt iodine was detected by direct titration. Results The average score of the four management indicators was 94.1 in Longyan city. The adjusted goiter rate of children aged 8 - 10 years old was 1.9%. The median of urinary iodine was 278.6 μg/L, among which less than 100 μg/L accounted for 4.57%(32/700), 100 -＜ 200 μg/L accounted for 24.00%(168/700), 200 - ＜ 300 μg/L accounted for 25.29%(177/700), and higher than 300 μg/L accounted for 46.14%(323/700). The using rate of qualified iodized salt was 98.86%. The coverage rate of iodized salt was 99.50%, the qualified rate of iodized salt was 99.35%, and the rate of non-iodized salt was 0.50%. All the indicators had reached the national standard to eliminate IDD. Conclusions After achieving the stage goal of eliminating IDD, the disease is stable and the effect of control measures are significantly. But the iodine provided has a trend of more than suitable. Therefore, it is reasonable to reduce the current salt iodine content.

OBJECTIVETo study the blood pressure (BP) changes in the liver transplant recipients.

METHODSA total of 206 patients without preoperation hypertension received liver transplantation in our hospital from February 2001 to July 2005. The BP level and serum immunosuppressant concentration at preoperation and various time points post operation were determined.

RESULTSCompared with the preoperation, the average systolic and diastolic pressure was significantly increased at the 2 week, 1, 2, 4 and 6 months post operation. The mobility of hypertension increased significantly after liver transplantation, with the highest mobility (46.49%) at the 1st month post operation. There was no linear correlation between the immunosuppressant (FK506) concentration and the BP level at any time point.

CONCLUSIONThere was a high hypertension incidence after liver transplantation. Although the use of immunosuppressive drugs accompanied with the BP increase, there was no linear correlation between the immunosuppressant concentration and the BP level post operation.

Objective To evaluate the possible interactions among different impact factors possibly affecting the treatment efficacy of 131I in Graves′ disease (GD). Methods Six hundred and thirty two GD patients that had been treated by 131I, with or without antithyroid drugs (ATD), were included in this study. The impact factors were pre-defined as age (x1), sex (x2), mass of thyroid (x3), course of disease (x4), initial symptom (x5), condition of disease (x6), ATD treatment duration (x7), effective half life time (x8), maximum 131I uptake rate (x9), total dose of 131I (x10), dose of 131I per gram of thyroid (x11), TRAb (x12), TSI (x13), TgAb (x14), and thyroid microsomal antibody(TMAb) level(x15). Interactions among different impact factors were studied by t-test, χ2 test and multi-variant logistic regression. Results Age, mass of thyroid, ATD treatment duration, maximum 131I uptake rate, dose of 131I per gram of thyroid tissue and TSI level were identified as independent impact factors affecting the 131I treatment efficacy on GD (χ2=6.908, t=-4.063, χ2=13.558, t=-2.553, t=4.528, χ2=9.716, all P<0.05) by uni-variant and multi-variate analyses. Loglinear and general linear model analyses showed that there existed multiple multiplicative and additive interactions among the factors of age, mass of thyroid, ATD treatment duration and maximum 131I uptake rate (likelihood χ2=8.176, P>0.05; F=2.928, 1.992, 2.629, 2.215, all P<0.05), which indicated that the treatment efficacy with co-existing multiple factors was not equal to simple summation of single factors. Conclusions The interactions among multiple factors can cause indi-rect effect on 131I treatment, which might guide the prescription of 131I dosage for GD treatment.

Objective To understand the current situation of iodine deficiency diserders(IDD) in Longyan City and to evaluate the effect of prevention and control measures of IDD in order to provide evidence for formulating prevention and control tactics. Methods During the year of 2006 and 2007, the 30 primary schools were screened by population proportion survey(PPS) from the 7 counties of Longyan City. Forty children aged 8-10 years in each school were randomly selected as a group to examine thyroid, and 7 children in each group were selected to measure the urine iodine and the salt iodine at the same time. The goiter rote, the median urinary iodine, the consumption rate of qualified iodized salt, the iodine salt coverage rate, the rate of qualified iodized salt and the non-iodized rate were detected. Results The goiter rate of children aged 8-10 years old in Longyan City was 0.94%(79/8438). The median urinary iodine was 259.12 μg/L. The consumption rate of qualified iodized salt was 97.86% (1462/1494). The iodine salt coverage rate was 99.46%(1486/1494). The rate of qualified iodized salt was 98.38 (1462/1486), and the non-iodized rate was 0.54% (8/1494). Conclusions All indicators have reached the national standard of eliminating IDD in Longyan City.

This paper presents the preliminary investigation on chondromalacia patella at our department in recent years. A random cluster sampling survey covering 2743 normal persons was carried out. The prevalence rate is 36.2%. It was found that, applying transmission electron microscope and immunohistochemical methods on to cartilage tissues of the abnormal region, articular cartilage necrosis was in direct proportion with the abnormal pressure, while the restoration capability of local chondrocytes was in inverse proportion with pathological changes and the pressure. The chondromalacia patella was produced by repeated abnormal stress acting on the carilage. The stress derived from the uncongruency and the decreasing in the contact area of patellofemoral joint when the subluxation or tilt of patellae was caused by the abnormal anatomical and biomechanical relationship. The initial lesion was at the matrix of cartilage,the collagen network was disrupted, then proteoglycan was lost. The microenvironment of chondrocytes was changed with degradation of matrix. So the chon drocytes became degenerative and necrosis from superficial to deep layer, then feed back the matrix again. Finally, the total cartilage layer might disappear, and the bone under cartilage might proliferate. At late stage, the cartilage was completely destroyed and had no self-restorative ability. Therefore, early diagnosis and treatment are necessary. It is highly suggested axis radiograph of the knee with the tibiae tuberositas localization are helpful to early diagnosis. Furthermore, JKY-Muscle Rehabilitation Instrument is invented for non-operative therapy. It enhances muscle power by selective training of the vastus medialis muscle using electrical stimulator to relieve pain and correct subluxation of patella with 90% efficiency (63% of excellent-effective rate) . In late stage, patellofemoral replacement is recommended. The excellent-effective rate is 86.3%.
