Objective To investigate the clinical manifestation and outcome of severe acute respiratory syndrome (SARS).Methods The clinical data of 233 patients with SARS admitted to China-Japan Friendship Hospital from April 2003 to June 2003 were analyzed,including clinical manifestations,laboratory findings,chest radiograph,outcome and mortality of SARS.Results There were 115 male and 118 female patients in this cohort,aged 13-86 (mean 42 8?18 5yr);43 3%of the patients had one or two kinds of underlying diseases;73 0% of the patients had a history of SARS close contact. Incubation period was 1-21 days (mean 4 9?4 1d).The initial symptoms were fever in 86 3% of the patients.The respiratory symptoms were found after the onset of 1-2 weeks.The laboratory abnormalities were decreased in WBC (56 7%) and lymphocytes (78 5%).Corticosteriod was used in 69 5% of the patients.There were 10 deaths (4 3%).The elder age,underlying diseases,continued high fever, thrombocytopenia,leucocytosis and bilateral lung involvement were the risk factors.Conclusion SARS is a new and strongly contagious disease,which mainly affects youth and people in their prime life.It has its own characteristic clinical manifestations.There is high mortality in severe cases.The prognosis is poor in patients complicated with diabetes,leucocytosis,lymphocytopenia,thrombocytopenia and elevated serum LDH and CPK.

Objective To analyze the effects of individualized lifestyle intervention on compliance and metabolic status of patients with type 2 diabetes mellitus (T2DM).Methods Two hundred T2DM patients were selected and randomly divided into experimental and control groups of 100 patients respectively.The experimental group was given individualized lifestyle intervention for 6 months in addition to conventional oral medications.The intervention was to prescribe diet control and exercise therapy according to the patients' individual conditions.The control group was given conventional treatment and verbal lifestyle intervention for 6 months.Comparison was made in patients compliance and various metabolic markers between the two groups.Results The percentage of conduction of diet control and exercise therapy in experimental group was significantly higher than control group ( Diet control:80 vs.52,x2=7.08,P=0.029;Exercise therapy:78 vs.44,x2=11.207,P=0.004).After intervention,the fasting plasma glucose (FPG),2-hour postprandial blood glucose (2hPG),glycated hemoglobin ( HbA1c),body mass index ( BMI),triglyceride ( TG),total cholesterol (TC),low-density lipoprotein ( LDL-C ),and insulin resistance index ( HOMA-IR ) in experimental group decreased significantly,and high-density lipoprotein ( HDL-C ) increased significantly [FPG:( 8.45 ± 1.46 ) mmol/L vs.(6.66 ± 0.67) mmol/L,P=0.000;2hPG:( 12.76 ± 2.25 ) mmol/L vs.(8.22 ± 1.79) mmol/L,P=0.000;HbA1c:(7.68 ± 1.06 ) ％ vs.( 6.48 ± 0.69 ) ％,P=0.000;BMI:( 25.90 ± 1.72 ) kg/m2 vs.( 22.81 ±1.41 ) kg/m2,P=0.016;TG:(2.57 ±0.68) mmol/Lvs.( 1.88 ±0.35) mmol/L,P=0.006;TC:(5.72 ±0.13) mmol/L vs.(5.14 ± 1.38) mmol/L,P=0.043;LDL-C:(3.28 ±0.10)mmol/L vs.(2.81 ±0.57)mmol/L,P=0.009;HOMA-IR:7.58 ± 0.19 vs.4.58 ± 1.98,P=0.000;HDL-C:( 1.29 ± 0.04) mmol/L vs.( 1.62 ± 0.27 ) mmol/L,P=0.003].The levels of FPG,2hPG,HbA1c,BMI,TG,HOMA-IR also decreased in control group after intervention compared with before intervention [FPG:( 8.67 ± 2.71 ) mmol/L vs.( 7.26 ± 1.21 ) mmol/L,P=0.001;2hPG:( 12.82 ± 2.15 ) mmol/L vs.( 10.85 ± 1.98 ) mmol/L,P=0.000,HbA1c:( 7.75 ± 1.08 ) ％ vs.( 7.01 ± 0.87 ) ％,P=0.002;BMI:( 25.82 ± 1.74 ) kg/m2 vs.( 24.23 ± 1.36 ) kg/m2,P=0.024;TG:(2.47 ±0.75) mmol/L vs.(2.13 ± 0.43 ) mmol/L,P=0.018;HoMA-IR:7.88 ± 0.20 vs.6.15 ± 2.01,P=0.042].No significant difference was found on the values of TC,HDL-C and LDL-C before and after intervention in control group (P ＞ 0.05).The effect of intervention of experimental group was more obvious when compared with control group ( FPG:P=0.036;2hPG:P=0.000;HbA1c:P=0.045;BMI:P=0.037;TG:P=0.022;HoMA-IR:P=0.000).Conclusion Individualized lifestyle intervention can improve the compliance of T2DM patients,and was in favor of control metabolic status of T2DM patients to delay the occurrence and development of complications.

Objective To learn the degree of the asthmatic patients'understanding of the disease, and to provide references for formulating the plan of the asthma patient's education and management infuture.Methods One hundred and one outpatients were surveyed by questionnaire face to face.Results Among 101 patients,the percentages of mild intermittent,mild persistent,moderate persistent and severepersistent asthma assessed by current symptom were 23%,29%,30%,18%.Among these patients thosewho understanding the inflammatory nature of asthma account occupied 70.3%,those who realizing the importance of inhaled corticosteroids(ICS)and taking ICS as the first-line medicine for asthma occupied67.3%,those who knowing the indication about rational use of short-acting beta-2-agonists(SABA)occupied 88.1%,those who realizing the goal of asthmatic therapy occupied 71.3%.All these results were significantly better than both the reporter in the asthma insights and reality in Asia-Pacific and the realizing degree to asthma of the respiratory professionals in Beijing's urban district hospitals in 1997.Conclusion After long term systematic education and management,asthmatic patient's understanding of the disease has been improved greatly.

Objective To explore the value of dynamic monitoring of the neutrophils/lymphocyte ratio ( NLR ) in peripheral blood for the prognosis of patients with bloodstream infection ( BSI ). Methods A retrospective study was conducted. 205 patients who were≥18 years old, their length of hospital stay>24 hours, and they were treated in the China-Japanese Friendship Hospital from January 2013 to October 2014 were enrolled. According to the 28-day survival, the patients were divided into survival group ( n=160 ) and death group ( n=45 ). The white blood cell ( WBC ), neutrophils count ( NEU ), neutrophils ratio ( Neut%), lymphocyte count ( LYM ), lymphocyte ratio ( Lym%), and NLR in peripheral blood were recorded at 1, 3, 7 days after admission. Receiver-operating characteristic curve ( ROC ) was plotted for evaluating the value of these factors on the 28-day prognosis, and logistic regression analysis was used to evaluate the risk factors for predicting the outcome. Results ①On the 1st day, WBC, NEU, Neut%, NLR, and procalcitonin ( PCT ) in the death group were significantly higher than those in the survival group [ WBC (×109/L ):15.28±8.23 vs. 11.58±6.55, NEU (×109/L ):13.34±7.53 vs. 10.03±5.31, Neut%:0.886±0.076 vs. 0.845±0.102, NLR:21.20 ( 13.10, 28.80 ) vs. 12.08 ( 6.81, 20.47 ), PCT (μg/L ):3.13 ( 0.85, 10.12 ) vs. 1.34 ( 0.36, 5.81 ), P<0.05 or P<0.01 ], while hemoglobin ( Hb ), platelet count ( PLT ), albumin ( ALB ) content were significantly lower than those of the survival group [ Hb ( g/L ):86.09±19.83 vs. 107.89±22.82, PLT (×109/L ):157.51±117.81 vs. 195.44±97.28, ALB ( g/L ):24.11±6.94 vs. 31.99±6.89, P<0.05 or P<0.01 ]. On the 3rd day and 7th day, WBC, NEU and NLR in the death group were significantly higher than those of the survival group [ WBC (×109/L ):16.61±10.25 vs. 8.91±4.93, 16.05±9.46 vs. 8.79±4.45; NEU (×109/L ): 14.15±9.98 vs. 6.97±4.64, 14.36±9.03 vs. 6.59±4.07; NLR: 24.13 ( 8.49, 38.26 ) vs. 5.52 ( 3.58, 8.87 ), 17.74 ( 10.74, 32.85 ) vs. 4.35 ( 2.78, 7.27 ), all P<0.01 ], and the LYM and Lym%were significantly lower than those in the survival group [ LYM (×109/L ):0.61 ( 0.38, 1.04 ) vs. 1.05 ( 0.78, 1.43 ), 0.69 ( 0.35, 0.92 ) vs. 1.37 ( 0.93, 1.76 );Lym%:0.039 ( 0.024, 0.101 ) vs. 0.135 ( 0.094, 0.186 ), 0.056 ( 0.033, 0.082 ) vs. 0.170 ( 0.108, 0.237 ), all P<0.01 ].②It was shown by ROC curve that the maximum area under the ROC curve ( AUC ) of WBC, NEU, Neut%, LYM, Lym%, and NLR about prognosis of BSI were observed on 7 days ( 0.777, 0.819, 0.905, 0.755, 0.880, 0.887 ). Based on Neut%>0.855 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 78.8%, specificity 89.1%, respectively. When Lym%<0.088 on the 7th day as a predictor of cut-off value of death on 28 days, the sensitivity was 89.5%, and specificity was 83.9%. When NLR>10.34 on the 7th day as a predictor of cut-off value of death in 28 days, the sensitivity was 81.8%, and specificity was 91.0%.③Survival analysis showed that the 28-day survival rate in the patients with 7-day NLR<10.34 was significantly higher than that in those with 7-day NLR>10.34 ( 95.0%vs. 34.1%,χ2=82.650, P=0.000 ).④It was shown by multi-factor logistic regression analysis that the levels of 1-day Hb and 7-day NLR were the independent prognostic predictors of 28-day mortality [ Hb: odds ratio ( OR ) = 0.946, 95% confidence interval ( 95%CI ) = 0.913-0.981, P = 0.003; 7-day NLR:OR=34.941, 95%CI=8.728-139.884, P=0.000 ]. Conclusions The trend of changes in NEU, LYM and NLR as shown by repeated routine blood examinations contributes to prediction of the outcome of patients with BSI. The levels of 1-day Hb and 7-day NLR are the independent prognostic predictors for 28-day mortality.

Objective To investigate the effects of artemin and its receptor GFRα - 3 on the invasion and metastasis of pancreatic cancer cells. Methods Human pancreatic cancer cell line MIA PaCa -2 was used in this study. Transwell cell culture chamber assay in vitro was used to detect the ability of invasion and metastasis of MIA PaCa -2 cells. The influence of artemin and GFRα -3 on the protein expression of MMP-2 and E-cadherin was investigated by Western blot and quantitative real time polymerase chain reaction-analyses (Q-RT-PCR). Results As the increase of artemin and GFRα -3, the invasion and metastasis of MIA PaCa- 2 was markedly increased [ 150 ng / ml concentration: Artemin group: 107.4 ± 11.4;GFRα3 group:94. 4 ± 9. 3 ;control group:34. 6 ± 7. 3, P < 0. 01 ]. With 150 ng / ml artemin and GFR-3,the synthesis of MMP-2 in MIA PaCa 2 cells was significantly increased than that in control group[ Artemin grou: (2. 17 ± 0. 05 ) × 108; GFRα3 group: (2. 02 ± 0. 03 ) × 108; control group: ( 1.02 ± 0. 02 ) × 108, t =6. 35,7. 32 ], while E-cadherin significantly decreased [ Artemin group: ( 0. 65 ± 0. 04 ) × 108; GFRα3 group: (0. 74 ± 0. 01 ) × 108; control group: ( 1. 36 ± 0. 03 ) × 108, t = 4. 27,5.61 ], the difference was statistically significant ( P <0. 01 ). Conclusions Artemin and its receptor GFRα3 could promote pancreatic cancer cell invasion and metastasis. This effect may be related to the up-regulated expression of MMP-2 and down regulated expression of E-cadherin.

Objective To investigate the expression and the role of osteopontin(OPN)and matrix metalloproteinase-9(MMP-9)in the invasion and metastasis of pancreatic carcinoma.Methods Human pancreatic cancer cell line MIA PaCa-2 was cultured in vitro.The location of OPN protein in pancreatic tumor cell line was detected by immunofluorescence staining.100 cases of pancreatic cancer and 40 cases of adjacent normal pancreatic tissues were used to analysis.The expressions of OPN and MMP-9 were investigated by immunohistochemistry assay.Results OPN expressed in the cell membrane and cytoplasm,OPN and MMP-9 in pancreatic cancer tissues positive rates were 73.0%(73/100)and 68.0%(68/100),which were higher than that in adjacent normal pancreatic tissues(all P ＜ 0.05).OPN and MMP-9 expression were associated with pancreatic tumor grade,lymph node metastasis and perineural invasion of pancreatic cancer(P ＜ 0.05).OPN and MMP-9 in pancreatic cancer tissues were positively correlated(r,=0.39,P ＜ 0.01).Conclusions OPN and M MP-2 might play an important role in the development of invasion and metastasis of pancreatic carcinoma.OPN and MMP-2 might play synergetic roles in the progression of pancreatic carcinoma.
