Pulmonary fibrosis is a group of chronic lung diseases induced by various causes. Because of its complex etiology and pathogenesis,most of the pulmonary fibrosis diseases have no effective treatment currently and the quality of life and prognosis of patients are poor. Recent studies on biomarkers of susceptibility and effect associated with pulmonary fibrosis have made great progress, which is of great significance for screening and early diagnosis of the disease,and even for the evaluation of therapeutic efficacy and prognosis. This paper reviews some potential biomarkers of pulmonary fibrosis diseases,including the mucin 5B promoter variant and matrix metalloprotease-7 associated with idiopathic pulmonary fibrosis,heme oxygenase-1 and serum Se related to silicosis,Krebs von den Lungen-6,surfactant proteins-D and sphingolipids signaling associated with various pulmonary fibrosis, in order to provide new ideas for further research on the prevention and treatment of pulmonary fibrosis diseases.

Objective To evaluate the preoperative CT scanning in cardiac carcinoma.Methods 52 cases of cardiac carcinoma proved by operation and pathology were analysed.Results By CT scanning,the size of the tumor,it′s local extension and relation to the adjacent structures and lymph node metastases could be demonstrated.Conclusion CT scanning plays important role in the operability of the cardiac carcinoma and the planning of treatment.

Objective: To explore the correlation among plasma level of brain natriuretic peptide (BNP), serum D-dimer level and patient's status in patients with acute pulmonary embolism (APE).Methods: A total of 122 APE patients who were hospitalized from Mar 2012 to Dec 2015 were selected.According to right heart function and clinical symptoms, patients were divided into low risk group (n=61), medium risk group (n=36) and high risk group (n=25);after discharge, all patients were followed up for six months, then according to survival or not, they were divided into survival group (n=105) and death group (n=17).Plasma BNP and serum D-dimer levels were measured and compared among all groups, then correlation among BNP, D-dimer levels and severity of patient's status was analyzed.Results: Compared with low risk group, there were significant rise in levels of plasma BNP [(133.28±74.92)ng/L vs.(273.89±179.29)ng/L vs.(834.80±509.09)ng/L] and serum D-dimer [(761.80±333.65)ng/ml vs.(966.67±370.33)ng/ml vs.(1228.40±569.11)ng/ml] in medium risk group and high risk group, and those of high risk group were significantly higher than that of medium risk group, P<0.01 all.Compared with survival group, there were significant rise in levels of plasma BNP [(257.33±27.11)ng/L vs.(696.47±64.92)ng/L] and serum D-dimer [(818.57±64.92)ng/ml vs.(1513.25±48.14)ng/ml] in death group, P<0.01 all.Pearson correlation analysis indicated that plasma BNP, serum D-dimer levels were significant positively correlated with severity of patient's status (r=0.69, 0.41, P<0.01 both), and plasma BNP level was significant positively correlated with serum D-dimer level (r=0.79, P=0.002).Conclusion: Measurements of plasma BNP and serum D-dimer in APE patients are help to assess severity of patient's status and short-term prognosis, and provide basis for clinical individualized therapy.

The mature seeds and excised embryos of Dalbergia odorifera were used as materials to study the effect of moisture content on their survival, as well as the effect of rapid freezing and vitrification freezing method on seeds and in vitro embryos cryopreservation. The results showed that the germination rate and vigor decreased from 82.67%, 85% to 18.35%, 25% respectively, when the seed moisture content decreased from 15.04% to 8.14%; and the germination rate decreased from 82.67% to 37.50%, 25.37% respectively by vitrification freezing method and rapid freezing method, when the seed moisture content decreased from 15.04% to 9.37%. Among all the moisture content gradient, 12.35% moisture reached the maximal germination rate, which were 63.58% and 50.45% respectively by vitrification freezing and rapid freezing; and when the embryo moisture content was 26.32%, the germination rate decreased from 95.67% to 58.31% and 33.82% respectively by vitrification freezing and rapid freezing. And when the moisture content was in the range of 14.17% -21.34%, the germination rate was a bit of decrease. The experiment results showed that the optimum conditions of seed cryopreservation were: moisture content 12.35%, vitrification freezing; and the optimum conditions of in vitro embryo cryopreservation were: moisture 15.04%, vitrification freezing. In conclusion, the effects of moisture content on germination rate after cryopreservation in D. odorifera seeds and embryo were significant, and vitrification freezing method is much better than rapid freezing method.

BACKGROUND: The soft tissues would shrink with nasal framework collapse following surgical trauma, which cause aseptic inflammation, lead to parts of cartilage resorption. Accordingly, long-term saddle nose deformity usually accompanied by short nasal columella. Complications such as skin perforation or ulceration would appear if corrected the deformity using medical silicone rubber with large tension.OBJECTIVE: To explore the effectiveness of repairing post-traumatic saddle nose deformity with autologous costal cartilage transplantation.METHODS: A total of 21 cases with post-traumatic saddle nose deformity accompanied by short nasal columella were selected, including 6 males and 15 females, aged 16 45 years. All of the cases had trauma history and agreed with the treatment. The costal cartilage was obtained from the seventh rib and formed to babylon weeping willow leaf shape and columella nasi stent to repair post-traumatic saddle nose deformity. The "V-Y" progradation suture was used in the philtrum introcession and the botton of nasal columella to extend the nasal columella. The recovery of saddle nose deformity after transplantation, discharge of transplanted cartilage, as well as the incision scar status was observed.RESULTS AND CONCLUSION: The results were satisfactory and there were no complications after transplantation. All the cases were followed up from 6 months to 2 years. No case suffered costal cartilage grafts discharge or chondral deformation. The scar was little at the bottom of nasal columella. It is an ideal method for repairing post-traumatic saddle nose deformity using transplantation of autologous costal cartilage with "V-Y" progradation suture.

Objective To evaluate the effectiveness and safety of terazosin in the treatment of benign prostatic hyperplasia (BPH)patients with concomitant hypertension.Methods A singlecenter prospective clinical observational study was conducted from March,2006 to March,2010 in our center.The main endpoints were the changes of IPSS total score,diastolic and systolic blood pressures at the end of 4 weeks and 3 monthes compared with the baseline,The second endpoints were Qmax value at the end of 4 weeks and 3 monthes compared with the baseline,Safety was assessed by adverse events.Results There were 212 patients in the study recruited,and 189 patients completed the study.All patients had BPH combined with hepertension.All patients were randomly devided into two statistical analysis group,blood pressure well controled and not well controled group,In the well controlled group,the IPSS socre reduced from 22.31 ± 5.18 at baseline to 15.64 ±3.91 at the end of the 4th weeks and 13.16 ± 3.53 at the end of 3rd monthes in the blood pressure well controled group populatin( P ＜ 0.01 ).The Qmax were improved significantly from (7.87 ± 2.41 ) ％ at baseline to (14.19 ±2.64)％ at the end of the 4th weeks and (15.69 ±2.77)％ at the end of3rd monthes in the blood pressure well controled group populatin( P ＜ 0.01 ).Terazosin had moderate effect in blood pressure decreasing (P ＜ 0.05 ),and all patients were within normal blood pressure range.In the uncontrolled group,the IPSS socre reduced from 21.55 ± 4.82 at baseline to 15.44 ± 3.66 at the end of the 4th weeks and 12.96 ± 3.11 at the end of 3rd monthes in the blood pressure well controled group populatin (P ＜ 0.01 ).The Qmax were improved significantly from ( 8.27 ± 2.27 ) ％ at baseline to ( 14.26 ± 2.87) ％ at the end of the 4th weeks and ( 15.51 ±2.92) ％ at the end of 3rd monthes in the blood pressure well controled group populatin( P ＜ 0.01 ).Terazosin decreased BPH patient blood pressure with controlled patients and unctrolled patients additionaly to other blood pressure medicine (P ＜ 0.05 ),and no severe side effect occured.At the end of the study,all patients were taking drug continuously and were followed.Conclnsion Terazosin can significantly improve the symptoms and quality of life in BPH patients with hypertension with good safety and compliance.
