Background and purpose: The Testin gene is a candidate tumor suppressor gene located at 7q31.2. Our purpose was to investigate the expression of Testin gene, and its possible relationship with the clinicopathological features of human colorectal carcinoma. Methods: Semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry methods were used to investigate the expression of Testin in 60 specimens of colorectal carcinomas and corresponding adjacent normal mucosal tissues. The correlations of Testin to clinicopathologic features of colorectal carcinoma were analyzed. Results: The mRNA level of Testin was down-regulated in colorectal carcinomas. The positive rate of Testin protein was significantly lower than the paracancerous mucosal normal tissues (P<0.01). The expression of Testin protein and mRNA was correlated with infiltration, differentiation, Dukes stage, T stage,lymph node metastasis and distant metastasis (P<0.05), but not with patients' gender, age, site of cancer (P>0.05). The expression of Testin protein was lower in the tissues which were deeper infiltrated, poorer differentiated, advanced in Dukes stage and T stage, or with lymph node or remote metastasis. The expression of Testin mRNA was positively associated with that of Testin protein(r=0.75,P<0.05). Conclusion: The expression level of Testin is significantly down-regulated in colorectal carcinomas, which may be associated with the degree of infiltration, differentiation and metastasis of colorectal carcinoma. It suggests that Testin may be a valuable marker for assessing the prognosis and metastasis of colorectal carcinoma.

Objective To investigate the expression of platelet-derived growth factor-D (PDGF-D) and bascular endothelial growth factor(VEGF) in gastric carcinoma and elucidate the potential relationship between their overex-pression and clinical pathological characteristics. Methods Immunohistochemical assay was performed to detect the protein expression of PDGF-D and VEGF in tissues. Semiquantitative reverse transcription polymerase chain re-action (RT-PCR) was performed to evaluate the mRNA expression of PDGF-D and VEGF in part of random selec-ting gastric carcinoma samples. The correlation between the expression of PDGF-D and VEGF, and the relationship between the expression of PDGF-D, VEGF and the clinical pathological characteristics were analyzed. Results The protein expression of PDGF-D and VEGF in gastric carcinoma tissues were significantly higher than that in adjacent tissues and normal gastric mucosa(P <0.05) ;The expression of PDGF-D and VEGF correlated with TNM staging, depth of invasion and lymphatic metastasis (P < 0.05), while the expression of PDGF-D also correlated to histolog-ical differentiation (P < 0.05). There was a significant positive correlation between PDGF-D and VEGF at the mR-NA and protein expression levels (P < 0.05). Conclusion PDGF-D and VEGF specifically highly expressed in gastric carcinoma. The abnormal expression may play an important role in the carcinogenesis and metastasis of gas-tric carcinoma.

Objective To investigate the clinical therapeutic effect of Shenqi Fuzheng injection for treatment of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods A prospective clinical study was conducted. Fifty-eight consecutive patients with AECOPD were admitted in Departments of Respiratory Disease and Critical Care Medicine in Zhuozhou City Hospital of Hebei Province from January 2012 to December 2013. They were randomly divided into western medicine (WM) control group (28 cases, the routine treatment of WM) and integrated traditional Chinese medicine (TCM) with WM group (30 cases, on the basis of conventional therapy, Shenqi Fuzheng injection 250 mL intravenous drip was given once a day for a therapeutic course of 10 days). The duration of mechanical ventilation, the successful rate of weaning from ventilator, the rate of using ventilator again after weaning, the length of stay in intensive care unit (ICU), and mortality were recorded respectively in the two groups. Before and after treatment, the arterial blood gas analysis, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, clinical pulmonary infection score (CPIS), pulmonary function and dyspnea score were evaluated. Results Compared with the WM control group, the duration of mechanical ventilation (hours: 104±16 vs. 125±24) and the length of stay in ICU (days: 6.3±2.1 vs. 7.2±3.6) were significantly shorter, the rate of successful weaning from ventilator was obviously higher [73.3% (22/30) vs. 60.7% (17/28)], and the rate of using ventilator again after weaning was remarkably lower [13.3% (4/30) vs. 28.6% (8/28)] in the combined TCM and WM group, the differences between the two groups being statistically significant (allP < 0.05); the mortality was lower in the combined group [10.0% (3/30) vs. 10.7% (3/28)], but there was no statistically significant difference (P > 0.05). Compared with those before treatment, the pH value, arterial partial pressure of oxygen (PaO2), forced expiratory volume in 1 second (FEV1), forced vital capacity(FVC) and the ratio of FEV1/FVC were all significantly higher in the two groups after treatment, while the partial pressure of arterial carbon dioxide (PaCO2), APACHE Ⅱ score, CPIS score, residual volume/total lung capacity (RV/TLC), and the dyspnea score were all lower in the two groups after treatment, the more obvious changes in levels being after 10 days of treatment in combined TCM and WM group [pH: 7.44±0.04 vs. 7.40±0.08, PaCO2 (mmHg, 1 mmHg = 0.133 kPa): 59.1±11.9 vs. 68.1±12.4, PaO2 (mmHg): 70.5±6.9 vs. 65.1±7.4, APACHE Ⅱ score: 14.5±4.2 vs. 17.4±2.2, CPIS score: 5.3±2.4 vs. 7.6±1.4, FEV1 (L): 1.60±0.47 vs. 1.54±0.34, FEV1/FVC: (65.33±2.65)% vs. (62.00±3.25)%, FVC (L): 1.72±0.21 vs. 1.66±0.21, RV/TLC: (42.13±1.67)% vs. (43.12±0.95)%, dyspnea scores: 1.71±0.54 vs. 2.32±0.65, allP < 0.05].Conclusion Shenqi Fuzheng injection possesses certain clinical value in treatment of patients with AECOPD, as it can obviously improve the pulmonary function and the data of arterial blood gas analyses, and effectively relieve the clinical symptoms.

Objective To investigate the changes in serum procalcitonin (PCT) in patients with severe pneumonia, and to analyze its value on evaluating the clinical outcome of patients with severe pneumonia. Methods A total of 58 patients with severe pneumonia aged over 18 years, and admitted to intensive care unit (ICU) of Zhuozhou City Hospital of Hebei Province from January 2017 to July 2018 were enrolled. The patients were divided into recovery group (the symptoms and signs of pneumonia disappeared or improved, and the X-ray chest films improved or did not make significant progress) and deterioration group (the symptoms and signs of pneumonia persisted or progressed, while X-ray chest radiography progressed, as well as serious complications such as involvement of other organ functions due to deterioration of pulmonary infection or septic shock) according to the therapeutic outcome. The serum PCT levels at 1, 3, 5, 7, 9 days after severe pneumonia diagnosed were recorded, and procalcitonin clearance rate (PCTc) was calculated. The acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score was estimated within 24 hours when severe pneumonia was diagnosed. Receiver operating characteristic (ROC) curve was drawn, and the area under ROC curve (AUC) was calculated to analyze the value of PCTc on evaluating the clinical outcome of patients with severe pneumonia. Results Among 58 patients, 33 (56.9%) had better outcome after active treatment (recovery group), and 25 (44.1%) had worse condition (deterioration group). There was no significant difference in PCT level at 1 day or 3 days between the recovery group and the deterioration group [μg/L: 5.05 (3.89, 7.61) vs. 5.29 (4.15, 7.46) at 1 day, 4.59 (4.02, 6.90) vs. 5.70 (4.59, 7.28) at 3 days, both P > 0.05]. With the prolongation of treatment time, serum PCT level was gradually decreased in the recovery group, while remained at higher level in the deterioration group, which was significantly lowered at 5, 7, 9 days in the recovery group as compared with that in the deterioration group [μg/L:2.92 (2.09, 3.42) vs. 6.09 (3.24, 7.96) at 5 days, 1.94 (1.50, 2.07) vs. 7.65 (5.60, 10.52) at 7 days, 1.37 (0.91, 1.74) vs. 8.96 (6.09, 10.87) at 9 days, all P < 0.01]. PCTc at 3, 5, 7, 9 days in the recovery group were significantly higher than those in the deterioration group [15.10 (-17.80, 32.10)% vs. -1.53 (-20.80, 11.48)% at 3 days, 47.50 (30.25, 60.34)% vs. 6.25 (-14.58, 29.05)% at 5 days, 76.44 (53.18, 77.92)% vs. -11.20 (-66.75, -1.38)% at 7 days, 80.01 (59.86, 88.27)% vs. -38.15 (-99.38, -2.81)% at 9 days, all P < 0.05]. ROC curve analysis showed that PCTc at 3, 5, 7 and 9 days were valuable for evaluating the clinical outcome of patients with severe pneumonia, and 9-day PCTc had the greatest value, the AUC was 0.978 [95% confidence interval (95%CI) = 0.945-1.000, P = 0.000], which was higher than APACHEⅡ(AUC = 0.442, 95%CI = 0.280-0.610, P = 0.392); when the best cut-off value of 9-day PCTc was 93.00%, its sensitivity was 99.0%, and specificity was 87.3%. Conclusions The PCT level of patients with severe pneumonia remained at a high level, which was related with the deterioration of the disease. PCTc, as an index to evaluate the clinical outcome of patients with severe pneumonia, has good application value.
