CACNA1 S gene mutations can cause hypokalemic periodic pa- ralysis (HOKPP). The related research speculated that CACNA1 S gene was the candidate genes which affect meat quality traits. In the present ar- ticle, the biological characteristics of CACNA1 S gene, structure, genetic diseases and the research development were respectively reviewed so as to provide a reference for further research.展开更多

One of the unusual causes of nontraumatic rhabdomyolysis is hypokalemic periodic paralysis without secondary causes. Primary hypokalemic periodic paralysis is a rare genetic disease characterized by episodic attacks of muscle weakness due to decreases in serum potassium. A 30-year-old woman who had 3 episodic attacks of hypokalemic periodic paralysis was admitted in emergency room with sudden onset symmetrical muscle weakness. After several hours, she started to complain myalgia and severe ache in both calves without any changes. Laboratory test showed markedly elevated creatine phosphokinase, lactic dehydrogenase levels with hypokalemia, rhabdomyolysis resulting from hypokalemia was diagnosed. Here, we report an unusual case of rhabdomyolysis caused by severe hypokalemia, which was suggested a result of familial hypokalemic periodic paralysis.展开更多
目的探讨低血钾型周期性麻痹(hypokalemic period paralysis,HOPP)患者的临床及骨骼肌病理特点。方法回顾性分析2005年9月—2012年12月在河北医科大学第三医院做骨骼肌活检的HOPP患者20例,均行血钾、肌酸激酶、心电图及甲状腺功能检查...目的探讨低血钾型周期性麻痹(hypokalemic period paralysis,HOPP)患者的临床及骨骼肌病理特点。方法回顾性分析2005年9月—2012年12月在河北医科大学第三医院做骨骼肌活检的HOPP患者20例,均行血钾、肌酸激酶、心电图及甲状腺功能检查。结果 20例患者中,原发性HOPP组16例,甲状腺功能亢进合并HOPP组(TPP组)4例。TPP组的起病年龄较原发性HOPP组晚,(42.75±9.36)岁vs(24.81±5.49)岁(P<0.01);原发性HOPP组与TPP组分别有43.75%(7/16)和25.00%(1/4)的患者存在血清肌酸激酶水平异常增高;2组患者血钾水平差异无统计学意义,(2.82±0.30)mmol/L vs(2.58±0.13)mmol/L);20例患者中,有8例(40.00%)骨骼肌活检见肌纤维胞浆中存在典型"管聚集"现象,其中原发性HOPP组7例,TPP组1例。结论低血钾型周期性麻痹"管聚集"的发病率为40.00%,8例患者存在肌纤维网结构紊乱、"管聚集"现象,原发性HOPP组"管聚集"现象较TPP组更常见;原发性HOPP组发病年龄较早。展开更多
