Objective To evaluate the diagnostic and prognostic evaluation of Procalcitonin (PCT)levels detection for elderly patients with severe pulmonary infection.Methods 60 elderly patients with severe pulmonary infection were selected,as the infected group,wherein 45 cases with bacterial infection,15 cases with non -bacterial infections.Another 60 cases elderly patients excluded infectious diseases were selected as the control group.PCT,CRP and WBC levels in two groups were detected and compared.The infection group was randomly divided into two groups,each of 30 cases,the control group received conventional anti -infection treatment,while the observation group developed solutions to optimize antimicrobial drugs by detecting changes in PCT and CRP.Antibiotic course,antimi-crobial drug costs,superinfection and adverse reaction rates in two groups were recorded and compared.Results PCT,CRP levels and WBC in the infected group were (17.4 ±11.3)ng/mL,(43.5 ±18.7)mg/L and (10.4 ± 7.3)×109 /L,which in the control group were (0.4 ±0.2)ng/mL,(6.3 ±3.6)mg/L and (5.4 ±1.4)×109 /L,the difference was statistically significance (t =7.369,9.570,3.295,all P <0.05 ).PCT levels of bacterial infection group was (27.2 ±14.7)ng/mL,which in non -bacterial infection group was (8.2 ±2.7)ng/mL,the difference was statistically significant (t =7.369,9.570,3.295,all P <0.05).Antibiotic course,antimicrobial drug costs,superin-fection and adverse reactions in the observation group were significantly lower than those in the control group,the difference statistically significant (t =6.994,27.71,χ2 =6.171,6.984,all P <0.05).Conclusion PCT detection has an important value of infection diagnosis especially in elderly patients with severe pulmonary infection,and can be used as the basis for antibiotic treatment.

Objective To observe and compare the clinical efficacy,recurrence rate and safety of differ-ent courses of inhalation fluticasone propionate in treatment of children with cough variant asthma. Methods A total of 101 children with cough variant asthma in our hospital were randomly divided into three treatment groups,all with the same therapy drug -fluticasone propionate and with the treatment time of two months, six months and nine months respectively. Clinical efficacy and treatment compliance were followed up during the treatment. After discontinuation,observation for the relapse of cough was followed up for 6 months. In inhalation therapy before and after,bone mineral density( BMD) and blood cortisol,electrocardiogram were monitored re-spectively to observe its safety. Results Three groups of children with cough were all get effective control,with no significant difference(H=5. 2894,P=0. 0710). The two months treatment group(A group)was more easy to relapse than the six months treatment group( B group) and the nine months treatment group( C group) after drug withdrawal,statistically significant(χ2 =4. 858 1,P=0. 027 5;χ2 =4. 482 6,P=0. 034 2). But after drug with-drawal,there was no significant difference in the rate of relapse in B and C group(χ2 =0. 022 2,P=0. 881 4). There were few changes in laboratory values about morning serum cortosol concentrations. There was no signifi-cant decrease in BMD after treatment. No other adverse events were observed in this study. Conclusion Flutica-sone propionate inhalation treating children cough variant asthma has good effection. A long period of treatment scheme(6 months)has better curative effect and lower recurrence rate after drug withdrawal.

Objective To study the effect of the genetic factors on the occurrence and development of type 2 diabetes mellitus(T2DM) and its general genetic pattern.Methods 21 T2DM cases,as proband,were investigated for T2DM genealogical tree.The heritability of T2DM was estimated by Falconer method.T2DM segregation rate and genetic pattern were evaluated with Penrose's method,Li-Mantel-Gart method and the threshold value model method of Jiang San-Duo.Results The prevalent rate of T2DM in first-degree relatives was 7.6%,which was higher than that in general population.The heritability of T2DM was 46.8%.The s/q score was 3.312 with Penrose's method,which was near to 1/q1/2.The segregation rate P was 0.131,which was lower than 0.25.The theoretical prevalent rate in first relatives was 8.0%,while the investigated prevalent rate was 7.6%.Conclusion There is an obvious heritable trend in T2DM.It is fit to the multi-factorial inheritance pattern but the mono-gene heritability model.

Ninety fresh umbilical cords of newborns were harvested and dissected. There were 86 cords with double arteries and single vein and 4 cords with only 1 artery and 1 vein. The outer and inner perimeter of single artery, double arteries and the vein was 3 8?0 3mm vs 6 2?0 3mm, 2 4?0 2mm vs 4 6?0 2mm and 10 0?0 4mm vs 10 8?0 4mm at empty and flatened state, respectively. The diameter of vein at 20mmHg filling pressure and single and double arteries at 80mmHg was 7 2?0 3mm, 4 8?0 1mm and 3 9?0 8mm, respectively. According to these values, various drainage and perfusion metal tubes were designed and evaluated both in vitro and in vivo. By using these tubes,extracorporeal circulation was established successfully via umbilical artery and vein in a newborn who suffered from cardiac arrest after birth. The results suggest that CPB through umbilical artery and vein is simple, practical and effective.

Objective To evaluate the outcomes of thoracoscopy-assisted mini-incision procedure in patients with lung cancer.Methods From January 2003 to June 2003,66 patients with non-small cell lung cancer were treated in our hospital by lobectomy combined with mediastinal lymph node resection using thoracoscopy-assisted mini-incision(36 patients,VATS Group)or traditional surgery(30 patients,traditional group).The clinical and follow-up data of the two groups were compared after the operation.Results No significant difference was found in the operation time between the VATS and traditional groups(114.6?47.4)min vs(123.3?43.9)min,t=-0.768,P=0.449],while the postoperative hospital stay of the VATS group was significantly shorter than that in the traditional group (9.2?1.4)d vs(10.5?1.7)d,t=-3.408,P=0.001].Log-rank test showed that the survival curve in the two groups was comparable(?2=0.270,P=0.605).Cox regression model indicated that the pathological characteristics(risk ratio:3.912,P=0.000),TNM stage(risk ratio:3.737,P=0.000),and lymph node metastasis(risk ratio:15.495,P=0.000)were independent,unfavorable prognostic factors for the disease;whereas,no relation was detected between the thoracotomy incision and prognosis(P=0.414).Conclusions Thoracoscopy-assisted mini-incision procedure is a safe and reliable approach for patients with lung cancer with satisfying outcomes.

Objective To explore the efficacy of endoscopic surgery for juvenile nasopharyngeal angiofibroma.MethodsDuring 27 years from March 1980 to July 2007,we performed endoscopic surgery on totally 19 patients with nasopharyngeal angiofibromas.According to Radkowski Stating,five of the patients were stage ⅠA,ten were stage ⅠB,and 4 were stage ⅡA.Before the endoscopy,superselective embolization was performed in all the cases via bilateral maxillary arteries.Results All tumors were successfully resected by endoscopy.The intraoperative blood loss was 200-600 ml.One of the stageⅡA patient developed cerebrospinal rhinorrhea during the endoscopic resection,and thus received repair of the middle turbinate by a mucosal patch immediately.In this series of patients,no massive epistaxis,intracerebral infection,or blindness occurred.Follow-up at three months after the surgery by nasoscopy showed epithelialisation of the nasal mucous membrane without residual tumor tissues.Meanwhile,otoscopy revealed normal light reflex of the eardrum,no fluid in the middle ear.Of the patients,eleven were followed up for one to five years,during which none of them had recurrent tumors confirmed by nasoscopy or CT scan.Conclusions Endoscopic resection of nasopharyngeal angiofibroma results in little trauma and few blood loss after superselective embolization.Experience and surgical skills are key points for the operation.
