Purpose　To investigate whether thoracotomy can induce lung injury in the operative side and the protection by ambroxol in this procedure.　Methods　24 patients with esophageal carcinoma who were performed esophagectomy with anastomosis over the arcus aortae were randomized into 2 groups:an ambroxol group (ambroxol 1 g iv gtt qd×3,preoperatively) and a controlled group without any respiratory medication.General anesthesia by tracheo-cannula combined with continuous epidual anesthesia were used in all the patients.Bilateral broncho-alveolar lavage(BAL) was carried out after intubation preoperatively and before removal of the cannula postoperatively.Total Phospholipid(TPL),Saturated Phosphaytidylcholine(SatPC) and Total protein(TP) in the BALF were measured.The ratio of SatPC/TPL and SatPC/TP represented the activity of PS.　Results　In the controlled group,SatPC/TPL and SatPC/TP of the left lung(operation side) showed significant difference(P<0.05),compared with the right side(non-operation side).In the ambroxol group,no significant difference of such ratio was showed.　Conclusions　Thoracotomy can induce lung injury and bring out the decrease of PS and increase of protein exudation in the operative side.Large dose of ambroxol can promote in synthesize and secretion of PS and protect those changes.

Objective:To systematically review the effects of statins in the treatment of the patients with pneumonia or sepsis, and to provide evidence-based basis for the using of statin in treatment of pneumonia or sepsis.Methods:PubMed, Embase, The Cochrane Library, CNKI, WanFang Data and VIP were searched for randomized placebo-controlled trials of statins published from the establishment time of datebases to January 31, 2015.The qualities of the included studies were independently assessed by two reviewers and the relevant data was extracted for analysis using Review Manager 5.3. Results:Nine trails involving a total of 1 227 patients were included.①A total of 6 studies about the mortality of hospitalized patients were included in the Meta-analysis;compared with placebo group, statins didn’t improve the mortality of hospitalized patients with pneumonia or sepsis;risk ratio (RR)= 0.83,95%CI (0.63,1.08),P=0.17.②A total of 7 studies about the rates of mechanical ventilation usage or ICU admission of the patients were included in the Meta-analysis. Compared with placebo group,statins didn’t improve the rates of mechanical ventilation usage or ICU admission of the patients with bacteria infection;RR= 0.99,95% CI (0.96,1.03),P=0.62.③A total of 4 studies about the levels of C reaction protein (CRP)were included in the Meta-analysis. Compared with placebo group, statins significantly reduced the levels of CRP;mean differences (MD)=-8.30 mg·L-1,95%CI (-12.13,-4.47),P<0.0001. Conclusion:Statins can not significantly reduce both the in-hospital mortality and the rates of mechanical ventilation usage or ICU admission, but can significantly reduce the plasma CRP levels, and reduce the inflammation.

Objective:To develop health-related physical fitness measurement scale and assess its reliability and validity among older adults.Methods:The health-related physical fitness measurement scale was developed through Delphi method and field investigation method.And the authority coefficient, Kendall's coefficient and variation coefficient were analyzed.A multi-stage random sampling technique was adopted to select 410 older adults to investigate the reliability and validity of health-related physical fitness measurement scale with test-retest reliability, Cronbach's α coefficient and Guttman Split-Half coefficient and structural validity by IBM SPSS 20.0 and AMOS 22.0.Results:The health-related physical fitness measurement scale consisted of 3 dimensions (organic function, motor function, physical adaptive capacity) and 15 indexes.The Cronbach's α coefficient was 0.84.The Spearman-Brown correlation coefficient and Guttman Split-Half coefficient were both 0.82.The test-retest reliability between the first measurement and retest after 1 week was 0.84.Three factors were extracted by exploratory factor analysis, which were basically consistent with the theoretical concept of the scale, but the items of the theoretical conception were different from the actual ones.Confirmatory factor analysis based on the theoretical conception showed that all the indexes met the requirements of reference value as well(χ 2/ df=2.38, GFI=0.94, AGFI=0.91, CFI=0.92, TLI=0.91, TFI=0.92, RMSEA=0.06). Conclusion:The health-related physical fitness measurement scale has good reliability and validity in measuring the health fitness level of the elderly population in Guangzhou.

Objective To evaluate the impact of autoantibodies to angiotensin Ⅱ type 1 receptor AT1-AA on clinic outcomes of delayed graft function (DGF) grafts.Method We reviewed the records of all 139 consecutive adult recipients who received single kidney transplantation and clinical management between Jan.2010 and Dec.2012 in our centre.The serum levels of AT1-AA were measured by a streptavidin-enzyme-linked immunosorbent assay.All patients with DGF were enrolled in this study and divided into two groups:(1) AT+ DGF group (serum AT1-AA positive,11 cases) ;(2) AT-DGF group (serum AT1-AA negative,23 cases).All clinical and laboratory data were recorded in our transplant database system at each visit.Result 139 recipients were enrolled.The overall presence of DGF was 24.5％ (34/139).The incidence of DGF in patients with high binding AT1-AA was significantly higher than that in those with low binding of AT1-AA (11/24 vs.23/115,45.8％ vs.20.0％,P＜0.05).In addition,longer duration of renal replacement therapy (59 ± 32 vs.47 ± 26 months,P＜0.05),higher resistance index (0.80 ± 0.10 vs.0.72 ± 0.10,P＜0.05) of allografts and more severe acute tubular injury (2.7 ± 0.5 vs.1.8 ± 1.1,P＜0.05)/acute tubular necrosis (0.9 ± 0.5 vs.0.5 ± 0.3,P＜0.05) were observed in AT + DGF group than in AT-DGF group.One-year graft survival and death censored graft survival were similar between two groups (90.9％ vs.95.7％,P＞0.05).Conclusion Presence of high binding anti-AT1 receptor had detrimental impacts on initiation and development of DGF.

Objective To evaluate the efficacy and safety of imatinib in chronic myeloid leukemia (CML) patients and analyse the factors affecting the survival. Methods 135 CML patients receiving imatinib were evaluated for hematologic, cytogenetic, and molecular responses and adverse events. Results The median follow-up was 20 (range 3-67) months. The rate of cumulative complete hematological response (CHR), major cytogenetic response (MCyR), complete cytogenetic response( CCyR ) and complete molecular response (CMoR) in chronic phase CML patients were 97.9 %, 78.3 %, 72.2 % and 35.1%, respectively.These rates were significantly higher in chronic phase than in accelerated phase and blastic phase (P ＜0.001).The rate of CCyR in low-risk patients was significantly higher than high-risk patients (P =0.048). The estimated overall survival (OS) rate at 1, 3 and 5 year for chronic phase patients were (97.8±1.5) %, (95.2±2.4) % and (91.9±3.2) %, respectively. The estimated progression-free (PFS) survival rate at 1, 3 and 5 year were (92.6±2.7) %, (85.5±3.7) % and (81.3±4.3) %, respectively. The OS rate for accelerated phase patients at 6, 12 and 24 month were (93.8±6.1) %, (72.5±11.8) % and (64.5±12.9) %, the PFS rate were (92.3±7.4) %,(64.5±14.7) %, (53.7±15.7) %, respectively. The OS rate for blastic phase patients at 6, 12 and 19 month were (86.4±7.3) %, (45.4±11.4) %, (19.4±9.8) %, the PFS rate were (70.1±12.6) %, (37.6±15.6) % and (18.8±15.4) %, respectively. The OS and PFS of patients in chronic phase who achieved CCyR or CMoR were better than patients only achieved CHR (P ≤0.001). Multivariate analysis for survival of chronic phase patients indicated that imatinib resistance was the unfavourable factor for PFS (P =0.000, RR =46.744) and OS(P =0.007, RR =20.270). The non-hematological toxicity of imatinib was slight and tolerable, severe hematological toxicity was the major reason for dose reduction or drug discontinuation. Conclusion The efficacy of imatinib in chronic phase CML patients is significantly superior to which in accelerated phase and blastic phase; Achieving CCyR even CMoR is the most important thing for longer survival, iinatinib resistance is the major problem in the treatment with imatinib.

Objective:This study aimed to compare the clinical efficacy and prognosis between rituximab plus fludarabine and cyclophosphamide (FCR) and fludarabine and cyclophosphamide (FC) regimens for patients with chronic lymphocytic leukemia (CLL). Methods:The clinical data of 58 patients with CLL treated with FCR or FC regimens from December 2002 to January 2012 were analyzed retrospectively. Therapy efficacy and prognosis were compared between the two groups. Results:Among the 58 pa-tients, 27 (44.4%) experienced complete remission (CR) in the FCR group and 31 patients (19.4%) experienced CR in the FC group (P=0.039). The overall response rate (ORR) of the FCR group was higher than that of the FC group (81.5%and 51.6%, respectively, P=0.017). Fourteen patients achieved MRD-negative rating after therapy. PFS and OS in MRD-negative patients were superior compared with the MRD-positive group (P=0.000, 0.003). The proportion of MRD-negative patients in the FCR group was higher than that in the FC group (37.0%and 12.9%, respectively, P=0.032). PFS in high-risk genetic patients was lower than that in low-risk genetic patients (P=0.011, 0.027). The OS time between the two groups did not exhibit any difference. Conclusion:FCR produced a high CR and ORR in patients with CLL. Many patients in the FCR group were responsive to the treatment. Thus, FCR could be a more effective regimen than FC for patients with CLL.

Objective To summarize the preliminary application results of ultrasound-guided biliary drainage tube replacement, present the corresponding technical points, and discuss the operation strategy and clinical application value. Methods The clinical data of 60 patients who underwent ultrasound-guided biliary drainage tube replacement in Qilu Hospital of Shandong University between August 2014 and August 2020 were retrospectively analyzed. The operation procedure, clinical applications, and postoperative complications were summarized and analyzed. Results Fifty-eight of the 60 patients (96.67%) were successfully replaced with drainage tubes along the original sinus. Among them, dilated sinus tracts of 47 patients were placed with coarse-grade drainage tubes, and dilated sinus tracts of the remaining 11 patients were placed with the original type of drainage tubes, with the mean operation time of 15.8(12.0-19.0) min under local anesthesia. In total, bile was drained from 28 patients receiving PTCD drainage, 23 patients receiving gallbladder drainage, and 9 patients receiving T-tube drainage. The post-operation evaluation revealed that the drainage situation has improved, with a 100% effective rate. No obvious abnormality was found in the postoperative follow-up visit. Conclusion The replacement of drainage tube under ultrasound guidance is simple, safe and feasible, and it provides further promotion in clinical practice with sufficient data support.
