Objective To explore the influence of age factor on the treatment of cutaneous hemangioma with (90Sr-90Y) applicator.Methods A total of 224 babies and children of different ages with cutaneous hemangioma were treated by using 90Sr-90 Y applicator.Then,the relation between their therapeutic effects and ages were analyzed respectively.Results The differences in the therapeutic effect between group of one month to less than one year and group of one to less than five years,and group of one month to less than one year and group of five to ten years,and between group of one to less than five ages and group of five to ten years (P＜0.05),were statistically significant.With an increase of the age,the recovery rate gradually decreased,but their effective rate,improvement rate and ineffective rate increased.In the 199 well-healed or effective patients,the differences in the distribution of treatment course between group of one month to less than one year and group of one to less than five years,and group of one month to less than one year and group of five to ten years,were statistically significant (P＜0.05); but the difference in the distribution of treatment course between group of one to less than five ages and group of five to ten years was not statistically significant (P＞0.05).The number of treatment course presented an increased tendency with an increase of the age for patients.Conclusions The age of patients is a factor influencing the therapeutic effect on cutaneous hemangioma with 90 Sr-90Y applicator.The younger the patients,the better their therapeutic effects,the shorter their courses of treatment,and the smaller the adverse reaction of beta ray.

In late 1998, a novel paramyxovirus named Nipah virus, emerged in Malaysia, causing fatal disease in domestic pigs and humans with substantial economic loss to the local pig industry. Pteropid fruitbats have since been identified as a natural reservoir host. Over the last two decades, the forest habitat of these bats in Southeast Asia has been substantially reduced by deforestation for pulpwood and industrial plantation. In 1997/1998, slash-and-burn deforestation resulted in the formation of a severe haze that blanketed much of Southeast Asia in the months directly preceding the Nipah virus disease outbreak. This was exacerbated by a drought driven by the severe 1997-1998 El Ni?o Southern Oscillation (ENSO) event. We present data suggesting that this series of events led to a reduction in the availability of flowering and fruiting forest trees for foraging by fruitbats and culminated in unprecedented encroachment of fruitbats into cultivated fruit orchards in 1997/1998. These anthropogenic events, coupled with the location of piggeries in orchards and the design of pigsties allowed transmission of a novel paramyxovirus from its reservoir host to the domestic pig and ultimately to the human population.

Objective To better promote the health education and health promotion among patients with chronic disease, general practitioners (GPs) in the community should master the knowledge of non-communicable diseases (NCDs). This paper aimed to describe the current situation of GPs' knowledge about prevention and treatment of NCDs. Methods Self-designed questionnaires were issued to 1 077 GPs in community health service centers, and all GPs finished the questionnaire without assistance. The content of questionnaire includes the general information of GPs and six questions focusing on NCDs. Results Overall, 1 076 GPs completed the questionnaire, and the response rate was 99.9% (1 076/1 077). With regard to the six questions about NCDs, 90.4% (973/1 076) of GPs were well aware of the diagnosis of hypertension. Apart from that, the knowledge of diabetes mellitus (60.9%, 655/1 076), factors related to NCDs (70.2%, 755/1 076), the concepts of mental illness (52.0%, 560/1 076) and the clinical significance of tumor markers (87.9%, 946/1 076) among GPs were adequate, while more than half of the GPs did not know a lot about home oxygen therapy. Conclusion The mastering level of knowledge about prevention and treatment of NCDs among GPs varies that they need further improvement.

Objective To investigate the changes in intrapulmonary shunting during controlled hypotension induced by sodium nitroprusside(SNP)in patients undergoing naso-endoscopic operation.Methods Forty ASAⅠorⅡpatients of both sexes(23 male,17 female)aged 16-50 yrs weighing 50-75 kg undergoing naso-endoscopic operation under general anesthesia with muscle relaxation and mechanical ventilation were studied.Radial artery was cannulated for direct BP monitoring and blood sampling.Right internal jugular vein was cannulated and the catheter was advanced into right ventricle.Blood sample taken from right ventricle was used as mixed venous blood instead of blood from pulmonary artery.ECG,MAP,HR and P_(ET) CO_2 were continuously monitored during operation Cardiac output was monitored with noninvasive cardiac function monitor(NC-COM.)based on impedance principle.SNP infusion was started at the beginning of operation at 1-3?g?kg~(-1)?min~(-1) and was then adjusted.MAP was reduced by 30%-40% and maintained at this level until the end of operation.Blood samples were taken from artery and right ventricle simultaneously before SNP infusion(T_1,baseline)at 30 and 60 min of hypotension(T_2,T_3)and at 20 min after BP returned to the baseline level(T_4)for blood gas analysis.Qs/Qt was calculated.Results Qs/Qt was significantly increased during controlled hypotension at T_2 and T_3 as compared to the baseline value(P＜0.01)and returned to the baseline level at T_4.HR was increased and cardiac output and stroke volume was significantly reduced during hypotension as compared to the baseline value.Conclusion The intrapulmonary shunting is increased and the hemodynamics is depressed during SNP-induced controlled hypotension and they return rapidly to baseline level after SNP is discontinued.No hypoxemia develops during SNP- induced hypotension.

Objective To study the effects of Yunnan BaiYao on the expressions of c-fos and c-jun mRNA in HPDLFs and explore the potential mechanism that Yunnan BaiYao promotes the proliferation and differentiation of HPDLFs.Methods The HPDLFs tissue was obtained from the extracted healthy premolar.The HPDLFs used underwent four to six passages.Cells were divided into untreated group,positive control group and treated group.In treated group,HPDLFs were co-cultured with Yunnan BaiYao solution for 4h with gradient concentration.The expressions of c-fos and c-jun mRNA were determined by RT-PCR.Results The results showed that the expressions of c-fos and c-jun mRNA were up-regulated significantly in treated group compared with control group (P＜0.05) Conclusion Yunnna BaiYao can upregulate the expressions of c-los and C-jun mRNA in HPDLFs.Through upregulating the expressions of c-fos and c-jun mRNA in hPDLs,Yunnan BaiYao can promote proliferation and differentiation of ossification of HPDLFs to induce bone formation.

Objective To investigate the effects of output power,action time and radiofrequency(RF) needle on the cool-tip radiofrequency ablation(RFA) by experimental tools and to determine the value of ultrasonography in size evaluation of RFA zone.Methods The cool-tip RFA to fresh calf liver were monitored by ultrasound.The experiments by single electrode needle were performed with different combination of output power (80 W,120 W) and time (5 min,8 min,10 min).The cluster needle was used for assessment at 5 min with different output power(80 W,120 W).After the end of trial,the longitudinal specimens were cut open.The view and size of the ablation zone were recorded with naked eyes.The pathological changes displayed by optical microscope were recorded as well.Results The measurement of ablation zone with naked eyes showed with the ablation zone expanded with time in 80 W-power cases,but the pace of expansion slowed down,but in 120 W-power cases,expansion of the ablation zone was not obvious; the ablation zone in 120 W-power was bigger than that in 80 W-power at 5 min,their difference decreased with time,and the ablation zones were similar at 10 min.The cluster needle can produce ablation zone with lesser aspect ratio than that of single electrode needle,consequently similar to circle.Ultrasonic measurement of the ablation zone had real discrepancy.Most of longitudinal diameters were greater than the real ones,while in large ablation lesions,vertical diameters were often less than the real ones.Under optical microscope,no change could be found in shape and structure of the cells in ablation zone.Conclusion The output power and performing time have impact on ablation.The high-power output increased heat production as well as reduction of heat conduction.Compared with single electrode needle,the cluster needle produced ablation zone closer to real hepatic tumor,thus has more reliable effect to small hepatocellular carcinoma with diameter around 2 cm.The ultrasond has a great significance in RFA guidance,but it could not accurately define the border of ablation zone.
