Objective To study PFSDQ-M in evaluating meal-induced hypoxemia in patients with chronic obstructive pulmonary disease.Methods PFSDQ-M scores were collected from 63 COPD patients;49 of them were performed spirometry and meal-related SpO2 monitoring.On the basis of different lung function parameters,data analysis was used to assess the relationship between PFSDQ-M and meal-induced hypoxemia.Results The SpO2 fluctuation during eating period was of significant difference in COPD patients with 3 respective levels of pulmonary function parameters (P

Objective To monitor pulse oxygen saturation(SpO_2)continuously in patients with chronic obstructive pulmonary disease (COPD) so as to study its clinical implication.Methods SpO_2, thoracic and abdominal respiratory activity was continually recorded during meal time by PSG in 19 patients with COPD. Body mass index and lung function were measured respectively. Results SpO_2 was lower after meal(P

Objective To assess the safety and efficiency of Angioseal device in patients undergoing coronary percutaneous procedure.Methods A prospective trial was carried out in 260 patients undergoing angiograph and angioplasty during october 2002 to July 2003.All patients were divided into two groups: Angioseal closure device and manual compression.Results In angiography,the time to hemostasis was (1.8?0.9)min by Angioseal and (25.3?13.4)min by manual compression(P

Objective Analyse the causes,diagnosis and treatment for delayed hemorrhage after distal radical gastrectomy.Methods Retrospective study on 45 patients combined with intro-abdominal hemorrhage after distal radical gastrectomy from January 2008 to June 2013.Results Thirteen patients combined with delayed hemorrhage in these 45 patients,all of 13 patients had intro-abdominal hemorrhage in 1week to 4 weeks after operation.And 5 of the 13 patiens were intermittent intro-abdominal hemorrhage 1 week after operation,these patients were demonstrated the blood come from gastroduodenal artery pseudoaneurysm fracture by CT and DSA examine,and they were cured by interventional embolization.Other 8 patients were marginal ulcer hemorrhage diagnosed by gastroscope,and they stoped bleeding with the help of gastroscope.Conclusions The causes of delayed hemorrhage after distal radical gastrectomy were complicated,and CT,DSA and endoscope can use for diagnosis.What was more,interventional embolization and endoscope were helpful for curing the intro-abdominal hemorrhage,avoiding re-operation.

In order to reform the medical talent evaluation system, establish evaluation systems of physician competency, and implement physician resources management systems according to work position, and the compensa-tion system which reflects the value of medical services, The basic principles and standards of different physician tiers and grades are created in Shenzhen based on literature review, expert consultation and the methods from the American Centers for Medicare and Medicaid Services ( CMS) . Some results have achieved, including medical competency as-sessment of a certain number of physicians in the pilot project ( the coincidence rate of special hospitals is higher than general hospitals, respectively 78. 9% and 44. 8% ), comprehensive personnel systems reforms in public hospi-tals, and the trial selection of medical talents. The paper also provides some implications:The cognition of all sectors of society and physician themselves should be improved, Transitional policies for position recruitment and performance pay needs further improvement. Meanwhile, the grade evaluation system of non-physicians must also be given greater attention.

Objective To investigate the prevalence of thyroid disorders and positive thyroid autoantibodies,and evaluate the necessity for universal thyroid screening during the second and third trimesters of pregnancy.Methods The pregnant women during the second and third trimesters who visited Shanghai Jiaotong University Affiliated First People's Hospital between June 2006 and February 2008 were chosen for thyroid screening by determining serum free triiodothyronine,free thyroxine,thyrotropin,thyroid peroxidase antibody (TPOAb),and thyrotropin receptor antibody.A personal and family history of thyroid disease and other autoimmune diseases was investigated by questionnaire.The pregnant women were divided into high risk or low risk groups for thyroid disease based on their personal or family histories.Results A total of 2 101 pregnant women were screened,712 ( 33.89％ ) of them were identified to suffer from thyroid disorders or with positive thyroid autoantibody.The prevalence of thyroid dysfunction was increased in high risk group.While in low risk group( n =1 983 ),the prevalence of clinical hypothyroidism was 2.27％ ( n =45 ),subclinical hypothyroidism 11.60％ ( n =230 ),clinical hyperthyroidism 0.20％ ( n =4 ),subclinical hyperthyroidism 1.06％ ( n =21 ),hypothyroxinemia 6.45％ ( n =128 ),and euthyroid with positive TPOAb 10.74％ ( n =213 ) in our study.Pregnant women with positive TPOAb were susceptible to thyroid dysfunction.It was shown that 79.74％ of pregnant women with thyroid disorders were diagnosed by universal thyroid screening.Conclusions 33.89％ of pregnant women in the second and third trimesters were identified to suffer from thyroid disorders or positive thyroid autoantibody by universal thyroid screening.Increased prevalence of thyroid dysfunction was found in pregnant women with positive TPOAb.79.74％ of pregnant women with thyroid disorders might be missed if screening was made only in the high risk cases.

ObjectiveTo investigate the influence of positive serum thyroid peroxidase antibody (TPOAb) on pregnancy outcomes in biochemically euthyroid women during gestation.MethodsFrom July 2006 to December 2010,in the prenatal care unit all pregnant women,who had no medical and family history of thyroid diseases,underwent thyroid function screening.Serum TPOAb was tested among those pregnant women with euthyroidism.Pregnancy outcomes,including obstetric complications,neonate birth weight,and Apgar score,were compared between 185 TPOAb positive women and 1417 TPOAb negative women.ResultsCompared with TPOAb negative women,it was more frequent for TPOAb positive women to suffer from various obstetric complications.The prevalences of umbilical cord entanglement ( 18.9％ vs 12.9％,RR =1.47,95％ CI 1.06-2.03,P＜0.05 ),threatened premature delivery or abortion (3.8％ vs 1.0％,RR =3.83,95％ CI 1.57-9.37,P＜0.05 ),intrauterine growth retardation (5.4％ vs 0.8％,RR =6.96,95％ CI 3.00-16.17,P＜0.01 ),and neonatal pneumonia ( 4.9％ vs 1.3％,RR =3.83,95％ CI 1.75-8.40,P＜0.01 ) in the group of TPOAb positive women were higher than those in the group of TPOAb negative women.Apgar score of those newborns whose mothers had positive TPOAb was 9.27 ±1.13 at one minute and 9.44 ± 1.09 at five minutes,being lower than that of the TPOAb negative group (9.49 ±0.69 and 9.68 ±0.52,both P＜0.01 ).The rate of newborns with Apgar score at 7 or less by 5 min in group with positive TPOAb was higher than that of group with negative TPOAb ( 1.6％ vs 0.1％,RR =11.49,95 ％ CI 1.93-68.31,P＜ 0.05 ).ConclusionsThese results indicate that pregnant women with normal thyroid function but positive TPOAb may be liable to increase risk of serious pregnancy outcomes,such as threatened premature delivery or abortion,intrauterine growth retardation,and a lower Apgar score in neonatal.

Objective To evaluate a new TNM staging system inclusive of intraperitoneal free cancer cells in terms of postoperative survival of patients with gastric cancer. Methods Free cancer cells (FCC) in the peritoneal washes of gastric cancer patients were estimated by measuring CEA mRNA levels using real-time RT-PCR. After 5-year follow-up, we get the cut-off value of CEA mRNA level by using MedCalc software to analyze the ROC curve. When CEA levels are more than the cut-off value, it may considered as FCC(+), and then using FCC(+) as distant metastasis (MI) to make a new TNM staging and analyze patients life-span. Results (1) Under the ROC curve analysis, when the cut-off value of CEA mHNA level was at 31.21 copies/ml, the Youden's index is the highest. (2) When FCC (+) considered as M1 to make a new TNM staging, the 5-year survival rate showed as below: Ⅰ-Ⅱ, P=0. 134; stage Ⅱ-Ⅲ P=0.004 and Ⅲ-Ⅳ P=0.022,repecetively. Conclusion (1) The best cut-off value of CEA mRNA levels for FCC in peritoneal washes is 31.2 copies/ml. (2) Our study demonstrated that application of FCC(+) in the TNM staging may have a better estimation of prognosis of patients suffering from advanced gastric cancer.
