Objective To explore the diagnostic and prognostic significances of platelet parameters changes in Kawasaki disease(KD).Methods The platelet total(PLT),mean platelet volume(MPV),platelet distribution width(PDW)and plateletcrit(PCT)were measured in 23 cases of KD on acute febrile phase and early recovery phase.It was compared with 33 cases suffered from other febrile diseases during the same period and in similar ages.Each KD child should accept the cardiology ultrasonic examination.Results The level of PLT,PCT increased in KD patients.It was more significant in early recover period than in acute febrile period(P0.05).PLT negatively correlated with MPV,PDW(r=0.358,0.268 Pa0.05).Conclusions The changes of platelet parameter play a very important role in diagnosis of KD.But it still can not be certain that whether the changes can help us estimate the variety of the patients condition and prognosis of KD children.It requires further study.

Objective To explore the clinical characteristics of Gitelman syndrome in children and the difference between Gitelman syndrome and Bartter syndrome.Methods Clinical date,biochemical tests and therapy of 6 patients diagnosed as Gitelman syndrome in Beijing children′s hospital from Mar.to Dec.2006 were retrospectively analyzed.At the same time,the relative articies of Gitelman syndrome and Bartter syndrome were reviewed.Results The symptoms of 6 patients appeared early.The age of onset of Gitelman syndrome at infancy stage,the main complains were growth delay,weakness,tetany.All patients had normal blood pressure.The biochemical tests showed hypocalemic,hypomagnesium,alkalosis and hyperreninemia.But the concentration of aldosterone was normal or little higher.The manifestations of all patients were relieved after taking both potassium and magnesium.Conclusion Gitelman syndrom and Bartter syndrome have differences at clinical syndrome and machanism of onset.

OBJECTIVE:To observe the clinical efficacy and safety of different doses of atorvastatin in the treatment of chron-ic subdural hematoma(CSDH). METHODS:One hundred and tweaty-eighie CSDH patients selected from our hospital during Jun. 2013-May 2015 were divided into observation group(n=62)and control group(n=66)in accordance with random number table. Both groups were given conventional treatment of brain cell nutrition. Control group received Atorvastatin tablet 20 mg,po,qd;observation group received Atorvastatin tablet 40 mg,po,qd. Both groups were treated for 6 months. Clinical efficacy,CSS and ADL score,hematoma volume,the levels of serum inflammatory factors (hs-CRP,MMP-9,IL-6,TNF-α) were observed in 2 groups. ADR was recorded during treatment and recurrence rate was also recorded. RESULTS:2 patients withdrew from observa-tion group and 6 from control group. Finally,120 patients met the criteria were included,with 60 cases in each group. Total re-sponse rate of observation group(88.3%)was significantly better than that of control group(73.3%),with statistical significance (P<0.05). After 1,3,6 months of treatment,CSS score,hematoma volume,the serum levels of hs-CRP,MMP-9,IL-6 and TNF-α in 2 groups were significantly decreased,while ADL score was increased significantly;the improvement of above indexes in observation group was significantly better than in control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). The recurrence rate of control group(13.3%)was significantly higher than that of observation group(3.3%),with statistical significance(P<0.05). CONCLUSIONS:Daily dose of shows ator-vastatin 40 mg better therapeutic efficacy and lower recurrence rate in the treatment of CSDH with good safety.

Objective To investigate the effects of low frequency ultrasound (LFU) on the proliferation and apoptosis of smooth muscle cells (SMCs) in rabbits with carotid atherosclerosis(CA).Methods CA models were established in 30 New Zealand rabbits using a high fat diet and air-drying.They were randomly divided into a control group and four LFU groups:group A received 0.5 W/cm~2 LFU for 5 min/d,group B 0.5 W/cm~2 for 10 min/d, group C 1 W/cm~2,5 min/d,and group D 1 W/cm~2,10 min/d.The rabbits' carotid arteries were autopsied after 20 d of the LFU treatment.The expression of PCNA and TUNEL staining were used to explore the proliferation and apopto- sis of SMCs,and the proliferation rates (PRs) and apoptosis rates (ARs) were calculated.Results Compared with the control group,the PRs in groups B,C and D were significantly lower,while the ARs in groups B,C and D were significantly higher.There was no significant difference in ARs or PRs among groups B,C and D.Con- clusion LFU can induce SMC apoptosis and inhibit SMC proliferation in rabbits with CA.

In order to develop a safer vaccine strain exploit Salmonella Pullorum vaccine strain as a live vaccine vector.Methods:AΔcrpΔasd mutant of S.pullorum C79-13 strain was constructed and it was developed E.coli donor strain mutant was generated through the two-step method introduced by χ7213 ( pREΔasd) was conjugated with the recipient of C 79-13Δcrp.The C79-13ΔcrpΔasd the transduction of recombinant suicide plasmid .Results:PCR and sequencing results showed that ΔsipBSL1344 was suc-cessfully constructed.The further study indicated that foreign DAP must be supplied for the ΔcrpΔasd mutant to grow,in addition,the asd gene was transmitted stably .Compared with C79-13 strain,the O antigens was identical to C79-13 strain,but the growth velocity was reduced significantly ,significantly reduced virulence .Conclusion: The ΔcrpΔasd mutant can accept asd+plasmid to construct host-vector balance lethal system , and this system can be used to express foreign gene efficiently and to develop potential oral multivalent vaccines.

Objective To improve the methods of making myocardial ischemia-reperfusion model and observe the changes of electrocardiogram and ultrastructure of myocardium in rats.Methods The chest of young male SD rats through the fourth intercostal space was opened,and the left coronary artery was tied with a silicagel tube,after 30 minutes,untied to perfuse.Changes of electrocardiogram were observed and recorded.After reperfusion,the levels of AST,LDH,and CK-MB were measured and the tissue samples of the infarct areas were examined by transmission electronic microscope.Results The 90 percent of total rats were made myocardial ischemia reperfusion model successfully.In myocardial ischemia reperfusion rats:the QRS wave of myocardial ischemia-reperfusion rats was much higher than that of control group;the level of cardiac enzymes increased;myocardial and vascular endothelial cells ultrastructure was damaged seriously.Conclusions The improvement of modus operandi is right.Ischemia reperfusion can cause evident damage of myocardial and vascular endothelial cells ultrastructure in rats,and damage of myocardial cells is more severe than vascular endothelial cells.
