Antithyroid drugs(ATD)is the main treatment for hyperthyroidism and its adverse reactions have been much concerned by physicians. Methimazole(MMI)and propylthiouracil(PTU)are the two common antitithyroid drugs used currently. Generally, the ATD are safe and effective, though their clinical adverse reactions are also relatively common. The toxic effects include liver damage and leukocytopenia, antineutrophil cytoplasmic antibody-associated pulmonary small-vessel vasculitis, hypoglycemia, allergic reactions, muscle impairment,and so on. They are usually reversible and disappear spontaneously when the drug is discontinued. However,the serious rare side effects can also occur and there may have potentially deadly threatening effects which need to be cautious for the clinicians. MMI is usually preferred over PTU because it has significantly fewer side effects. And unlike the dose-dependent side effects of MMI, there has no significant correlation between adverse reaction and drug dosage in using PTU. Moreover, PTU has more severe hepatotoxity than MMI, even fatal liver impairment and liver failure. The risk of liver damage from PTU is an important concern, particularly in children. For this reason, MMI is the first choice for treating children with hyperthyroidism.

Parathyroid carcinoma is a rare endocrine tumor.Clinical manifestations are varied with multiple organs involved,mainly due to hypercalcemia.So far the etiology and pathogenesis of parathyroid carcinoma are still unclear and preoperatively diagnosis is difficult.Technetium-99 m sestamibi scan and ultrasound can help to find the early lesions.Complete surgical resection with suspicious involved lymph nodes is the recommended treatment.Parathyroid carcinoma is insensitive to chemotherapy and radiotherapy.New immune therapy yields unsure efficacy.Therapeutic effect and prognosis mainly depend on primary surgical resection of the tumor.The disease recurs in more than 50％ of patients with poor prognosis.

Objective To reduce the incidence rate of sepsis caused by multidrug-resistant acinetobacter baumanni and provide the basis for clinical antibiotics use.Methods It is one retrospective case-controled study.Thirty-six patients with multidrug-resistant acinetobacter baumanni infection(case group) and 42 patients with non-multidrug-resistant acinetobacter baumanni infection(control group) admitted in PICU during 2009 to 2013 were enrolled in the study.Seven high risk factors including the irrational antibiotics use,the length of hospital stay,tracheal intubation,the length of mechanical ventilation,the basic diseases (hematologic malignancies,congenital heart disease,inherited metabolic diseases),use of central venous catheters and the length of using central venous catheters were analyzed.The drug sensitivity of multidrug resistant acinetobacter baumanni was detected.Results There were significantly differences in 7 high risk factors between case group and control group,including irrational antibiotics using (29 cases vs.18 cases),the length of hospital stay ＞7 d(35 cases vs.12 cases),tracheal intubation(22 cases vs.8 cases),mechanical ventilation ＞ 7 d (19 cases vs.2 cases),basic diseases (9 cases vs.3 cases),using of central venous catheters (18 cases vs.2 cases) and central venous catheters using ＞ 7 d(9 cases vs.1 cases) ;multidrug resistant acinetobacter baumanni had high resistance against penicillins,cephalosporins,aminoglycesides,quinolones,sulfonamides (94.87％,74.36％,76.92％,65.38％ and 56.41％),but had high sensitivity to carbapenems and tetracyclines (55.56％ and 77.78 ％).Sixteen cases infected with pandrug resistant acinetobacter baumanni infection (44.44％),4 cases infected with whole drugresistant acinetobacter baumanni (11.11％).Conclusion The irrational antibiotics use,the length of hospital stay,tracheal intubation,the length of mechanical ventilation,the basic diseases,central venous catheters and the length of using central venous catheters are the high risk factors of spesis caused by multidrug resistant acinetobacter baumanni; only carbapenems and tetracyclines can keep high sensitivity rate to multidrug resistant acinetobacter baumanni among clinical antibiotics.

Objective To explore the change of serum procalcitonin (PCT)in infectious diseases and the relationship between PCT and the severity of illness in children.Methods This was a single-center prospective study of serum procalcitonin concentration in children with infectious diseases.Ninty-five children with infectious diseases (mycoplasma infection 30 cases,viral infection 30 cases,bacterial infection 35 cases),hospitalized in PICU of Shengjing Hospital from April 2011 to April 2013,were divided into three groups:non-serious group(64 cases),serious group(20 cases)and very serious group(11 cases)according to pediatric critical illness score(PCIS).Bacterial infectious patients were divided into two groups:gram positive bacterial group(20cases),gram negative bacterial group(15 cases).Twenty children of non-infectious diseases during the same period were selected as the control group.Serum PCT levels were detected by using VIDAS BRAHMS PCT detection system(rapid semi-quantitative PCT test).Laboratory detection was conducted in Department of Laboratory Medicine,Shengjing Hospital of China Medical University.Results The serum PCT levels of the control,the bacterial infection,virus infection,and mycoplasma infection group were (0.41 ± 0.34) μg/L,(2.56 ± 0.38)μg/L,(0.52 ±0.44) μg/L and(0.21 ±0.10) μg/L.The serun PCT levels higher than or equal to 0.5 μg/L were defirned as positive.There was significant difference in PCT positive rate between bacterial infection group and the control grouP(x2 =28.05,P ＜0.05).The serum PCT levels of children with infectious diseases were higher than those of non-infection group,mycoplasma infection group and virus infection group(P ＜ 0.05).Besides,the PCT value of gram negative bacillus infection group was also obvious higher than gram positive infection group.There was no significant difference among the non-infection group,mycoplasma infection group and virus infection group(P ＞ 0.05).There was significant negative correlation between the serum PCT concentration and the PCIS score in children with infectious diseases (r =-0.579 ～-0.793,P ＜ 0.05).The higher concentration of PCT in children with the infectious diseases indicated higher severity illness scores,more complications,and longer length of hospital stay.Conclusions PCT may provide an informative and sensitive molecular marker for pathogen identification (bacterial infection,pneumonia mycoplasma infection or viral infection).In the early diagnosis of infectious disease,PCT assay can help predict the severity of the disease.

Objective To evaluate the role of 3 D spiral computerized tomographic angiography (SCTA) in microsurgery of separating craniopagus twins Methods A case of craniopagus twins underwent spiral CTA Image reconstruction was made by shaded surface display Result SCTA demonstrated osseous fusion in twins skull Parts of bone and dura mater were found to be absent in the fused area Two parts of brain tissues were linked together, and some area were fused Twins' one third of posterior superior sagittal sinuses were fused and converged into a common sinus One side of their transverse sinuses were fused Conclusion SCTA can clearlly reveal the abnormalities of skull, cerebrum, intracranial blood vessels, especially the stereostruction between intracranial blood vessels and skull SCTA is useful for intraoperative bone design and decision of surgical route and has important value in formulating surgical plans

C3 glomerulopathy (C3G) is referred to disease which is out of control of complement activation,degradation and deposition,then leads to predominant C3 deposition in glomerular and glomerular injury.The study found that C3b amplification in the circulation and/or glomerular basement membrane were the key factors that cause immune disorders.Combined with clinical and experimental research,this paper mainly discusses the pathogenesis,clinical characteristics,and treatment of the disease.

The recording and analysis for the neurons' single unit discharge is one of the important content among the comprehensive experiments in basic medicine.However,the traditional experiment cannot help the students to understand the mechanism of the action potential.According to the high comprehensive quality and high requirements of training in eight-year medical students,in the past two years,we have entrained the optogenetics into the single unit recording experiment and set up an experiment of neuronal discharge evoked by the optogenetics.In this article,we the introduce teaching design of the recording and analysis of the unit discharges induced by light genetics,sum up teaching experience and put forward our own thinking.
