Objective Analyzed the cause and time of hypokalemia complication that dexamethasone used for hyperthyroidism preoperative preparation.Methods The study consisted of 161 patients with hyperthyroidism disease,who were used the dexamethasone in his or her preoperative preparation at the First Affiliated Hospital of Zhengzhou University between August 2011 and July 2013.Results In the 161 hyperthyroidism patients,composed of 41 men and 120 women,twenty-seven patients happened hypokalemia and 92.6％ occurred after the first.Twenty-six men patients developed hypokalemia complication when used dexamethasone for hyperthyroidism preoperative preparation,while only 1 woman patient occurred the hypokalemia complication.Among the 11 patients who with a history of thyrotoxic periodic paralysis,10 cases occurred after given dexamethasone hypokalemia,only 1 case has no hypokalemia.Conclusion Dexamethasone and other drug used in hyperthyroidism preoperative preparation,which was rapid,safe and effective,but it can lead to hypokalemia complication,especial in the 24 hours after the first use,should be brought clinical doctors attentions,and give timely diagnosis and treatment.

Objective To analyse clinical characteristics of patients with epilepsy induced by playing Mah-jong.Methods The medical records of 14 epileptic patients who were admitted at the Epilepsy Center of PUMC Hospital chief complaint of Mah-jong induced epileptic seizures from 1996 to 2000 were retrospectively reviewed.Results 12 patients showed generalized tonic-clonic seizures and 2 patients showed partial seizures with secondary generalization. Interictally, normal EEG were found in 13 patients, and one patient was discharged. None patients recept anticonvulsant therapy for preventing seizures. Conclusion Mah-jong induced epilepsy, a reflex epilepsy, is probably related to thinking,spatial task and decision making while playing mah-jong. It is benign, and could be easily prevented by stopping playing Mah-jong.

Objective To explore the influence of retinoic acid (RA) on the expressions of insulin-like growth factor (IGF)-Ⅱ,type 2 IGF receptor (IGF-2R) and IGF binding protein (IGFBP)-2 mRNA and polypeptides in lungs of hyperoxia-exposed premature rats and its possible molecular mechanism. Methods On the 2nd postnatal day, 260 Sprague-Dawley(SD)preterm rats were randomly divided into 4 groups. Group Ⅰ: air + normal saline (NS) group; Group Ⅱ: hyperoxia(85% O_2) + NS group; Group Ⅲ: air+ RA group; Group Ⅳ: hyperoxia(85% O_2) + RA group. RA was injected to group Ⅲ, Ⅳ intraperitoneally (500 ?g/kg) since the 3rd day after birth, while NS was given to group Ⅰ,Ⅱ daily at the same time as group Ⅲ and Ⅳ. On day 4, 7, 10, 14 and 21 after birth, 8 rats in each group were killed. The mortality of preterm rats was recorded and lung radical alveolar counts (RAC) were examined. The mRNA analysis (RT-PCR) and polypeptides analysis (Western Blot) of IGF-Ⅱ, IGF-2R and IGFBP-2 were performed. Results 1. On the 4～7th day of exposure, the survival rate in all groups were similar. After 7 days of 85% O_2 exposure, the survival rate in group Ⅱ, Ⅳ dropped sharply and there was a significant difference comparing to group Ⅰ, Ⅲ( P

Objective To investigate the role of insulin-like growth factor (IGF)-Ⅰ , ⅠⅠ , platelet-derived growth factors (PDGF)-AA,-BB and keratinocyte growth factor (KGF) in various stages of the pulmonary development in rats. Methods All lung tissues of fetal and neonatal rats were collected at the gestational age 18, 20, 21 d, and 1, 4, 7, 10 and 21 d after birth. The expression of IGF-Ⅰ , IGF- ⅠⅠ , PDGF-AA and PDGF-BB was detected by immunohistochemistry and Western blot, respectively. The levels of IGF- Ⅰ , IGF-ⅠⅠ , PDGF-A, PDGF-B and KGF mRNA were measured by reverse transcription polymerase chain reaction (RT-PCR). Results The peak expression of IGF-Ⅰ was at 4, 7 and 10 d after birth. IGF-ⅠⅠ was detectable early in fetal lung development and decreased gradually until 21 d after birth. The changes of IGF- Ⅰ , ⅠⅠ mRNA were similar to IGF- Ⅰ , ⅠⅠ polypeptides. The PDGF-A,PDGF-B mRNA were abundant early in fetal lung development. The steady state of PDGF-A chain mRNA was significantly different only at 7 d (0. 97?0. 23,P0. 05). The PDGF-AA polypeptide was abundant early in fetal lung development, and the expression peak was found in 1, 4 and 7 d after birth. KGF mRNA was higher in the fetal samples than that of rats after birth, but no difference in postnatal rats at all time points. Conclusions Peptide growth factors may play a critical role in the development of lung in rats.
