Objective To discuss the diagnostic value of N-terminal-pro-brain natriuretic peptide (NT-proBNP) for patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) complicated with left heart failure. Methods Patients with medical history of AECOPD, or are diagnosed as AECOPD from March 2014 to February 2015 were involved in the study. Based on echocardiography and clinic characteristics , the patients were divided into left heart failure group (group A) and non-left heart failure group (group B). Related factors of elevated NT-proBNP in AECOPD and the diagnostic value of NT-proBNP for patients with AECOPD complicated with left heart failure were analyzed , and exclusive and diagnostic cutoff were worked out. Results In this study , 109 AECOPD patients were collected , including 21 patients in group A and 88 patients in group B. Multivariate linear regression analysis indicated NT-proBNP was positively associated with PCT (β=0.180,P = 0.011) and PAP(β = 0.333,P = 0.000), and negatively with LVEF(β = -0.511,P = 0.000)and the area under the ROC curve(AUC) was 0.959 (95% confidence interval:0.915-1.002,P = 0.000). The exclusive cutoff was 794.6 pg/mL(sensitivity:90.5%,specificity:92%), and the diagnostic cutoff 1 618 pg/mL(sensitivity:85.7%,specificity: 97.7%). Conclusions NT-proBNP can help to diagnose whether AECPOD patients are complicated with left heart failure. Besides left heart dysfunction and the state of systemic inflammation , pulmonary hypertension may be the reasons for the elevated NT-proBNP in AECOPD patients.

Objective To investigate the health seeking intention and its influencing factors among patients with type 2 diabetes in Chongqing Chronic Disease Management System.Methods Multistage cluster random sampling was used to investigate basic information,diabetes-related treatment situation including first heal seeking and reasons for choosing medical institutions in the last year.Relative risk ratios (RRR) and its influencing factors were analyzed with the method of multi-nominal Logistic regression,as community as a reference.Results Over the past year,38.02％ of type 2 diabetes patients preferred to hospitals above the county level,36.78％ preferred to pharmacy or clinics,and 25.21％ preferred to community health service centers.Univariate analysis showed that different education levels,family income levels,health insurance and therapies were significantly different from health seeking intention.Multi-nominal Logistic regression results indicated that higher educational level (RRR =2.39,95％ CI:1.20-4.78),higher income level (RRR =3.37,95％CI:1.44 -7.88),applying to specific diseases medical insurance (RRR =3.32,95 ％CI:1.72-6.42),the use of insulin and oral hypoglycemic agents (RRR =5.02,95％CI:1.15-22.00) of respondents were more inclined to the hospitals above the county level,rather than community health services.Conclusions Health seeking intention of type 2 diabetes patients preferred to hospital above the county level in Chongqing.Type 2 diabetes was an important disease of non-infectious chronic diseases,while the patients preferred go to utilize hospitals rather than community services.

OBJECTIVE: To investigate the expression of FLIP and PTEN in laryngeal Squamous cell carcinoma (LSCC), and the relationship between FLIP and PTEN. METHOD: The protein expression of FLIP and PTEN were examined by using immunohistochemical method in 45 cases of LSCC and 15 cases of para-carcinoma tissues. RESULT: FLIP protein positive expressive rate in the laryngeal squamous cell carcinoma cases (77.8%) was higher than that in the para-carcinoma tissues cases (33.3%, P < 0.05). The protein expression of FLIP was correlated with cervical lymph node metastasis, clinical stage and prognosis. On the other hand, PTEN positive expressive rate in the laryngeal squamous cell carcinoma (65.0%) was higher than that in the para-carcinoma tissues (0%, P < 0.01). The protein expression of PTEN was associated with tumor differentiation grade, clinical stage, cervical lymph node metastasis and prognosis. There was a negative relationship between the expression of FLIP and PTEN in LSCC. CONCLUSION The protein expression of FLIP may be an important prognostic marker for LSCC. The protein expression of PTEN was correlated with clinical stage, tumor differentiation grade, and cervical lymph node metastasis . Consequently, it could be used as a valuable marker for the prognosis of LSCC.

Objective To explore the value of susceptibility-weighted imaging (SWI) for the assessment of chronic renal injury. Methods Thirty-nine patients with clinical diagnosis of chronic renal injury (RI group) who underwent routine renal MRI and SWI examination were retrospectively analyzed. They were divided into mild injured group (15 cases) and moderate to severe injured group (24 cases) by estimated glomerular filtration rate (eGFR). At the same time, 17 volunteers without chronic renal injury who had normal serum creatinine (Scr) and blood urea nitrogen were recruited as control group. All subjects underwent routine renal MRI and SWI examination. The ratios of cortex to medulla were measured and calculated in both kidneys' magnitude image and susceptibility weighted image, which were indicated as C/MMAG and C/MSWI. Independent sample t test was used to compare the differences of C/MMAG and C/MSWI between control group and RI group, and paired sample t test was used to compare the differences betweenC/MMAG and C/MSWI in each group. One-way ANOVA was used to compare the difference of C/MMAG and C/MSWI between the control group and the different RI groups. ROC was employed to assess the diagnostic efficacy of C/MMAG and C/MSWI in renal injury. Pearson linear correlation analysis was used to evaluate the correlation between C/MMAG, C/MSWI and eGFR, Scr in patients with renal injury. Results The C/MMAG and C/MSWI in the RI group were 1.101±0.039 and 1.071±0.046, respectively. C/MSWI was obviously lower than C/MMAG, and the difference was statistically significant (t=5.056, P<0.01). There was no significant difference between C/MMAG and C/MSWI in the control group (P>0.05). The C/MMAG and C/MSWI in the RI group were obviously lower than those in the control group, and the difference was statistically significant (t=4.564, 6.122;P<0.01).The C/MMAG and C/MSWI in the mild injured group and the moderate to severe injured group were significantly lower than those in the control group, the difference was statistically significant (P<0.05). While the differences of those between mild injured group and moderate to severe injured group showed no statistical significance (P>0.05). The area under ROC of C/MMAG and C/MSWI in diagnosis of renal injury were 0.853 and 0.952, respectively. C/MMAG was positively correlated with eGFR (r=0.460,P<0.01). Conclusions Susceptibility-weighted imaging can be used to assess chronic renal injury. Although it cannot reflect the degree of renal function damage, it has some value in the early diagnosis of mild renal injury.

Objective: To improve the quality standard for Qiangli Pipa distillate formula. Methods: The chemical reactions for i-dentification in the old standard were deleted. TLC methods were established to identify Papaveris pericarpium, Eriobotryae folium and Platycodonis radix. The contents of morphine and codeine phosphate from Papaveris pericarpium were determined by HPLC. The chro-matographic conditions for morphine content determination were as follows: an Inertsil ODS-3 chromatographic column (250 mm × 4. 6 mm, 5 μ m ) was used, the mobile phase was acetonitrile-the mixture of 0. 01 mol·L-1sodium heptane sulfonate and 0. 02 mol ·L-1potassium dihydrogen phosphate with equal amount (10% phosphoric acid was used to adjust pH to 2. 8) ( 13: 87 ), the detec-tion wavelength was 220 nm ,the column temperature was 30 ℃, and the flow rate was 1. 0 ml·min-1. The chromatographic condi-tions for codeine phosphate content determination were as follows : an Inertsil ODS-3 chromatographic column (250 mm×4. 6 mm, 5 μ m ) was used, the mobile phase was acetonitrile-the mixture of 0. 01 mol·L-1sodium heptane sulfonate and 0. 02 mol·L-1s potas-sium dihydrogen phosphate with equal amount (10% phosphoric acid was used to adjust pH to 2. 8) ( 15: 85 ), the detection wave-length was 220 nm, the column temperature was 30 ℃, and the flow rate was 1. 0 ml·min-1. Results: TLC had obvious characteris-tics with clear and well-separated spots. Morphine showed a good linear relationship within the range of 3. 14-62. 8 μg·ml-1( r=1. 000 0) with the average recovery of 96. 69% (RSD=2. 41% , n=9). Codeine phosphate showed a good linear relationship within the range of 3. 52-87. 94 μg·ml-1(r=1. 000 0) with the average recovery of 95. 68% (RSD=2. 64% , n=9). Conclusion: The quality standard for Qiangli Pipa distillate formula is improved. The methods are easy-operated and accurate with good specificity, which are suitable for the quality control of Qiangli Pipa distillate formula.

Objective:To explore the risk factors of skin flap pigmentation after repairing skin and soft tissue defects of extremities using cutaneous neurovascular flap and to give some suggestions for prevention and treatment.Methods:From January 2013 to March 2020, 160 cases of extremities cutaneous nerve vascular flap with survival in Tangshan Second Hospital were retrospectively studied. According to the occurrence of pigmentation, they were divided into two groups: Group A (pigmentation group) and Group B (non-pigmentation group). The observation indexes included sex, age, injury cause, defect size, complete debridement, anastomosis of skin flap, sunscreen measures and postoperative infection. First, univariate analysis was carried out to screen the influencing factors of pigmentation in the cutaneous neurovascular flap, and then Logistic regression was used for multivariate analysis to screen the risk factors.Results:The postoperative follow-up time was 12 to 24 months, with an average of 17.9 months. A total of 29 patients (18.1%) had skin flap pigmentation. Univariate analysis showed that there was no significant difference in sex, age, cause of injury and defect area between the two groups ( P>0.05). Further multivariate analysis showed that incomplete debridement, lack of venous anastomosis, failure to take sunscreen measures and postoperative infection were the risk factors of pigmentation of cutaneous neurovascular flap ( OR=0.310, 0.335, 0.355、5.878, 95% CI=0.112-0.863, 0.115-0.975, 0.133-0.949, 2.069-16.697, P<0.05). Conclusions:Incomplete debridement, lack of venous anastomosis, failure to take sunscreen measures and postoperative infection are the risk factors resulting in pigmentation of neurovascular flap. It is important to perform prevention to reduce the incidence of pigmentation.
