Objective To investigate the new epidemiology and clinical manifestation of measles in children in recent years. Methods One hundred and twenty-eight cases of children′s measles were collected,and their epidemiological and clinical characteristics of age distribution,endemic distribution,vaccination,clinical manifestation,complication and misdiagnosis were discussed. Results Among the patients living in urban,90% cases were single dose vaccination,35% cases were between 3-8 years old,27% cases were less than 8 months old,59% cases were mild measles,27% cases were atypical measles,40% cases were misdiagnosed at first visit,and 67% cases of measles less than 8 months old were babies of vaccine immunized mother.Among the patients living in rural,68% cases had no vaccination,86% cases were at age of typical onset,61% cases were typical measles,7% cases were severe measles,and 28% cases were mild measles.Among all cases of measles,mild measles and atypical measles were as high as 41% and 16%,but typical measles were only 37%.In all patients,56% cases had typical measles rash,82% cases had Koplik′s spots,77% cases had typical onset of eruption,100% cases had higher fever in eruption stage,89% cases had typical downward sequence of eruption,93% cases had skin pigmentation,and 81% cases had desquamation. Conclusions Less than 8 months infants and single dose vaccinated pre-school children are newly susceptible group of measles.Mild measles and atypical measles markedly increased,with atypical clinical symptoms,variable rash and variant onset,but the character of aggravated fever in eruption stage scarcely changes.Infants of vaccine immunized mother and pre-school children are advised to vaccinate ahead of schedule.

Research on post-marketing Chinese medicine should be the systematic study from application to mechanism. Clinical evaluation is the basis of mechanism study, we can find the clue from clinical evaluation, then make a mechanism study to find the reason, then apply the results to clinic. So it is a virtuous circle. In order to achieve it, we cannot be limited to traditional Chinese medicine, we should form multi-disciplinary team under the direction of grand science thinking, try hard to put industry-university-research institute collaboration association to use, and if necessary, explore the new model of the whole nation system. An appropriate operation mechanism is very important.

Select patients diagnosed of hypertension in the first place in 16 hospitals and the patients were described by association rules analysis and distribution for the analysis in the study,in order to understand the information of diagnosis and treatment in hypertension patients in real world. The information include age, gender, admission condition, inpatient department, hospitalization expenses, western medicine comorbidities, the traditional Chinese medicine (TCM) syndrome and the medicine. The average age of patients was 64 years in the study. The proportion of men to women about 1. 10: 1. Admission condition is critical for about 10.12% of the total and more concentrated in the cardiovascular department. Hospital stay ranged from 8 to 14 d. Inpatients with medical insurance is 62.93%. Total hospitalization cost distribution most is the 5 000-10 000 RMB. Hypertension complicated with coronary heart disease, blood lipoprotein disorder disease; phlegm and blood stasis and Yin deficiency of liver and kidney are the most in TCM syndrome type. Promoting blood circulation and removing blood stasis is the major in Chinese medicine treatment. Western medicine treatment basically conforms to the guidelines. The most antihypertensive drugs is calcium antagonistst, accounting for about 81.2% of the total number. Class ACEI, class ARB, beta blockers, diuretics class are accounted for 43.0%, 43.4%, 42.4%, 42.4%, fixed compound is only 2 393, accounting for about 8%. the total frequency of five classes of antihypertensive drugs is 78 206 times. The principal conclusions of this analysis are as follows: the elderly people is the most in hypertension, more men than women; medical insurance is the majority type in hospitalization cost; nearly half of the population is combined with coronary heart disease; phlegm and blood stasis and yin deficiency of liver and kidney are the most in TCM syndrome type; western medicine treatment basically conforms to the guidelines. Combination therapy is more, less fixed compound preparation in western medicine. Chinese medicine is mainly to promoting blood circulation. Suggesting that the clinical treatment in strict blood pressure and at the same time, pay attention to combination therapy and the use of fixed compound preparation,it's useful to control the blood pressure better. Combined with traditional Chinese medicine and resolving phlegm and removing blood stasis, reduce the target organ damage, reduce complications, the prevention and control work of hypertension in China still faces enormous challenges at present. The result provides reference information for clinical medicine and medical research.

One hundred and fifty two actinomycetes were isolated from forty two radiation-polluted soil samples,using six different isolation media. Sixty cultures were chosen for 16S rRNA gene sequence and systematic analysis,which based on their morphology and ARDRA. Results of 16S rRNA gene sequences blasting showed that the strains were assigned to 12 recognized genera of actinomycetes,most of them fall within Streptomyces genus and a great deal of strains belonged to rare actinomycetes,which indicated a rich diversity of actinomycetes in the radiation-polluted soil.

Objective To investigate the flexibility of both the covered stents specially designed for use in intracranial vasculature and the delivering system in passing through the bone tube and the physiological curves of the cranial internal carotid artery(CICA)to reach the targeted area,the performance (adherence)of the covered stents in occluding vascular wall diseases and the impact on the vascular branches of the covered segment.Methods The covered stents specially designed for use in intracranial vaseulature were used to treat 13 patients with CICA diseases using endovascular techniques.There were 4 huge pseudoaneurysms,4 giant aneurysms,3 small wide-necked aneurysms,1 giant pseudoaneurysm with concurrent internal carotid cavernous fistula(CCF),and 1 CCF.Prior to the detachment of the covered stents,balloon occlusion test(BOT)of the internal carotid artery on the diseased side and whole-brain digital subtraction angiography(DSA)were performed in all the patients.Three to 16 months following procedure,DSA and clinical follow-ups were performed.Results Thirteen patients all tolerated the BOT well with the DSA demonstrating well-opened anterior and posterior communicating arteries.The covered stents and the delivering systems all successfully passed CICA to reach the targeted diseased area,with the diseased segments of the internal carotid artery including C3—C4 in 4 cases,C4—C5 in 4 and C6—C7 in 5.Immediately following the detachment of the covered stents,DSA demonstrated that 7 aneurysms were completely occluded,4 aneurysms had slight endoleak,and 1 CCF had markedly-decreased blood flow through the fistula.In the patient with concurrent pseudoaneurysm and CCF,the pseudoaneurysm disappeared and the blood flow through the fistula was markedly-reduced immediately following the stenting procedure.Apart from one patient with aneurysmal subarachnoid hemorrhage who died due to extensive vascular spasm on the 9th day following the stenting procedure,all the other 12 patients had unobstructed stented vessels on the follow-up DSA images,with 2 demonstrating slight stenosis.In the 6 patients with post-procedure endoleak,DSA showed that the endoleak in 4 patients had disappeared,one endoleak disappeared following the second stenting,and one CCF remained low-flow fistula.There was no sequela related to the occlusion of branches in the covered arterial segment.Conclusion The covered stents specially designed for use in the intracranial vasculature and the delivering system are both flexible enough to pass the tortuous CICA to reach the intracranial diseased artery,and are effective in managing CICA diseases.Further follow-up is still needed to determine the long-term effect of the covered stents,and the adherence of the covered stents needs further investigation.
