Objective To analyze the distribution and antibiotic resistance of pathogens isolated from sputum in early postoperative patients after esophageal surgery, and investigate the risk factors of pulmonary infections after esophageal carcinoma and reasonable application of antibiotics during perioperative period.Methods The clinical data of 414 patients with esophageal carcinoma who were admitted to the Affiliated Hospital of Binzhou Medical University from January 2012 to June 2014 were retrospectively analyzed.The second generation cephalosporins were used as preventive antibiotics for the 181 patients between January and December 2012 and the third generation cephalosporins were used for the 233 patients between January 2013 and June 2014.Sputum samples were collected and inspected before operation and in the first three days after operation for observing distribution and antibiotic resistance of pathogens.The incidence of postoperative pulmonary infection was observed in the two kinds of patients.The risk factors closely related to the occurrence of postoperative pulmonary infections were analyzed.Comparison of rate and univariate analysis were done by chi-square test.Multivariate analysis was done with logistic regression.Results The positive rate of early post-operative sputum culture was 24.64％ (102/414), 32.04％ (58/181) in patients receiving the second generation cephalosporins and 18.88％ (44/233) in patients receiving the third generation cephalosporins, respectively, with a significant difference between the two generations of cephalosporins (x2 =9.502, P ＜ 0.05).A total of 131 strains of pathogens were isolated from early postoperative sputum samples including 12 strains of gram-positive bacteria and 119 strains of gram-negative bacteria.The top three bacteria were Klebsiella pneumoniae subsp pneumoniae (33 trains), Acinetobacter baumannii (20 strains) and Pseudomonas aeruginosa (19 strains).The resistance rate of gram-negative bacteria in early postoperative sputum samples to meropenem, ciprofloxacin and levofloxacin were 5.0％-25.0％, 2.6％-15.2％, 2.6％-20.0％, respectively.Among cephalosporins, the resistance rate to ceftriaxone, cefotaxime, cefepime, ceftazidime, cefuroxime and cefazolin were 10.3％-20.0％ , 5.3％-30.0％ , 12.8％-31.6％, 15.4％-42.1％ , 21.2％-55.0％ and 15.2％-60.0％, respectively.The overall postoperative pulmonary infection rate was 18.60％ (77/414).The pulmonary infection rate of patients receiving the second generation cephalosporins was 26.52％ (48/181), which was higher than 12.45％ (29/233) of patients receiving the third generation cephalosporins (x2=13.326, P ＜ 0.05).The results of univariate analysis showed that smoking, chronic obstructive pulmonary disease, application of the second generation cephalosporins during the perioperative period and early postoperative sputum culture positive were correlated with the postoperative pulmonary infection after esophageal carcinoma surgery (x2 =5.149, 22.765, 13.326, 159.092, P ＜ 0.05).Multivariate statistical analysis with logistic regression demonstrated that application of the third generation cephalosporins during the perioperative period was independent protective factor of postoperative pulmonary infection (OR =2.582, 95％ confidence interval: 1.331-5.009, P ＜ 0.05).Conclusions The pathogens from sputum in early postoperative period after esophageal surgery are complicated with gram-negative bacteria as the main pathogens especially Klebsiella pneumoniae subsp, pneumoniae, and different levels of antibiotic resistance are ubiquitous.The third generation cephalosporins can effectively prevent the postoperative pulmonary infection after esophageal carcinoma surgery.

Objective To Explore the therapy of elderly patients with hypoproliferative acute myeloid leukemia.Methods Twenty-six elderly patients with hypoproliferative acute myeloid leukemia had received induction of CAG regimen and 15 cases were treated intensive chemotherapy after complete remission,then if achieving complete remission had received subsequent intensive chemotherapy: stand or reduce AA, DA or HA regimen.Results In 26 cases patients who received CAG regimen,the complete remission rate, partial remis sionrat and the totle total effective rate were 53.85％ (14/26), 19.23％ (5/26) and 73.08％ (19/26), respectively.Accordance with response to CAG regimen and the therapy after complete remission, 26 patients were divided into 3 groups:intensive chemotherapy after complete remission(CR1), non-intensive chemotherapy after complete remission(CR2) and non-remission(NR, including partial remission patients).The median overall survival of CR1 ,CR2 and NR were 13.5 months, 8.2 months, and 4.5 months, respectively.There was higher median overall survival of CR1 group than CR2 and NR groups (P =0.041,0.001, respectively).There was higher OS of CR2 group than NR group (P =0.064).No serious bleeding events were found in chemotherapy.Conclusion CAG regimen was an effective and little adverse effect regimen for the treatment of elderly H-AML,and with well tolerance in patients.Advisable intensive chemotherapy can prolong the patient's survival time after complete remission.

Objective To evaluate the clinical application and safety of CT-guided transthoracic cutting needle lung biopsy in diagnosing diffuse lung diseases. Methods By using automatic biopsy gun (14 & 16 gauge), CT-guided transthoracic cutting needle lung biopsy was performed in 29 cases with diffuse lung diseases. The samples obtained were sent for pathological and immunohistochemical examination. The sampling successful rate, the diagnostic accuracy and the occurrence of complications were analyzed. Results Technical success rate was 100%, and large size of sample enough for pathological and immunohistochemical examination was obtained in all 29 cases. Definite pathological diagnosis could be made in 25 cases, with the positive diagnostic rate of 82.8%. The main complications included pneumothorax and pulmonary hemorrhage. The symptoms in most cases were not severe and disappeared within one week after the treatment. Conclusion For the diagnosis of diffuse lung diseases, CT-guided transthoracic cutting needle lung biopsy is a safe, easy, effective and reliable method with high successful rate, high diagnostic value and fewer complications, in these respects this technique is superior to transbronchial lung biopsy, open lung biopsy and video-assisted thoracoscopic lung biopsy. Therefore, this technique should be popularized in clinical practice.

BACKGROUND: There are no ideal substitutes for meniscus. Meniscel allograft transplantation has become a feasible method to retain maniscal function following injury. Currently, the meniscus conservancy methods include fresh meniscus, low temperature preserved meniscus; freeze-dried meniscus.OBJECTIVE: To observe the long-term effects of meniscus allograft transplantation by different methods.METHODS: A total of 70 adult New Zealand rabbits were used, and 30 were selected as meniscus donors. The remaining 40 rabbits were divided into 4 groups (n=10): after meniscectomy, control group was not treated; fresh group underwent fresh meniscus allograft transplantation; low temperature group underwent low temperature preserved meniscus allograft transplantation; freeze-dried group underwent freeze-dried meniscus allograft transplantation. Of 30 donors, 10 received fresh meniscus transplantation, and the other received temperature preserved meniscus and freeze-dried meniscus transplantation 1 week after low temperature and freeze dried preservation. The rabbits were sacrificed 12 months after surgery for gross and histological observation.RESULTS AND CONCLUSION: The meniscus allografts of rabbits healed well, and no rabbits died. Gross observation showed that the appearance and elasticity of fresh meniscus group was similar to normal meniscus; tibial plateau was covered well, with no additional wearing in the cartilage of tibial plateau or condyles of femur. In low temperature and freeze-dried preservation groups,the meniscus grafts healed well, but their volume was small and the elasticity was poor; tibial plateau was only partially covered.Pathological observation suggested that fresh meniscus group had orderly arranged collage fiber and similar chondrocyte appearance, number and distribution to normal meniscus, while sparse collagen fiber end small number of meniscus grafts were observed in the other groups. Results show that meniscal allogrefting can survive, retain certain function and structure and prevent the degenerative changes of the knee joint. Moreover, fresh meniscal grafts exhibit best effects, as the grafts following low temperature or freeze-dried preservation degenerate and their volume diminish 1 year following meniscectomy.

Objective Methods To explore the value of VEGF levels in serum and pleural effusion for diagnosis of benign and malignant tumors, and evaluate clinical value of VEGF-A, C, D in malignant pleural effusion.Methods Serum and pleural effusion of 34 cases patients with lung cancer were collected in our hospital, the application of ELISA method for the detection of VEGF level in serum and pleural effusion in patients with lung cancer and with benign pleural effusion.VEGF-A, C, D levels were detected.Results VEGF levels in serum and pleural effusion in malignant group were significantly higher than those in benign group(P<0.05).In addition, patients with lung cancer before initial treatment, the VEGF levels in serum and pleural effusion of distant metastasis group were significantly higher than those of without distant metastasis group(P<0.05).There was a correlation between the level of VEGF and the malignant pleural effusion(r=0.878, P<0.05).No correlation existed between VEGF level and benign pleural effusion.The content of sVEGF-A in serum had no statistical difference in cancer group and benign group.Effusion supernatants of pVEGF-A content in lung cancer group were higher than those in benign effusion group(P<0.05).pVEGF-A and sVEGF-A levels were similar in benign effusion group. Effusion supernatants pVEGF-A in malignant group was higher than that in benign effusion group(P<0.05).pVEGF-A was significantly higher than that of sVEGF-A in malignant effusion(P<0.05).Serum VEGF-C, VEGF-D content had no significant difference between cancer group and benign group. pVEGF-C, pVEGF-D content had no significant difference between cancer group and benign group.Conclusion Level of VEGF in serum and pleural effusion detection would help to diagnose and differentially diagnose benign and malignant pleural effusion.Effusion VEGF-A is different in benign and malignant effusion, which may become benign and malignant effusion tumor markers.

Objective To evaluate the effects of hyperbaric oxygen (HBO) and cisplatin (DDP) on inhibition of A549/DDP cells in vitro and to explore the impacts of HBO on cell cycle and apoptosis.Methods The cytotoxicity of HBO and DDP was determined by Methyl thiazolyl tetrazolium (MTF) assay; flow cytometry (FCM) was used to investigate the impacts on cell cycle and apoptosis of cell line A549/DDP.Results Hyperbaric oxygen alone significantly suppressed A549/DDP cells proliferation (P ＜ 0.05),compared with control group of normal oxygen,and the inhibition ratio was 2.90％.DDP at concentrations ranging from 3 μg/ml to 24 μg/ml significantly inhibited the proliferation of A549/DDP cells in a dose dependent manner,that was concentrations of 3,6,12 and 24 μg/ml brought inhibition ratio of 1.87％,4.62％,11.15％ and 30.45％ ; Hyperbaric oxygen can enhance the inhibition effect of DDP to A549/DDP cells,when hyperbaric oxygen affiliated with DDP of concentrations above,the inhibition ratios were 4.37％,8.92％,21.88％ and 48.71％,respectively,which has significant difference with the single DDP groups.FCM analyses showed that HBO arrested A549/DDP cells at the S phase,that was cell number of G0/G1 phase reduced significantly and of S phase raised significantly,compared with normal oxygen group(P ＜0.01),that was the percentages of cells in S phase of control group were 9.5％ and HBO group were 20.9％,while the percentages of cells in G0/G1phasc were 82.2％ and 66.3％,respectively.In addition,there were more apoptotic cells in the HBO group with the percentage of 7.9％,while the percentage was 2.8％ in the normal oxygen group.Conclusion Hyperbaric oxygen could play together with DDP to inhibit A549/DDP cells proliferation.HBO could block the cell cycle at S period and induce apoptosis.

Objective To investigate the effect of early rehabilitation on rats' motor performance after moderate or severe experimental traumatic brain injury (TBI).Methods After adult Sprague-Dawley rats had received moderate or severe TBI,they were randomly assigned to either a 24 hour exercise group (group A),a 3-day exercise group (group B),a 7-day exercise group (group C) or a control group.Each group was composed of 8 rats.The exercise group endured forced treadmill training on an electric treadmill for 14 consecutive days initiated 24 hours,3 days or 7 days post TBI.The foot-fault and cylinder tests were performed on the 6th,12th,18th,24th and 28th day post injury.On the 28th day the rats were sacrificed and the brains were removed and frozen.The frozen coronal brain sections were stained with cresyl violet (CV) for quantitative evaluation of cortical lesion volume.Results The rats in groups B and C showed significant decreases in the percentage of left forelimb foot faults compared with the control group at the 18th,24th and28th day after injury.In addition,the rats of group C demonstrated significant decreases in the percentage of left forelimb foot-fault at the 12th day after injury.There was no significant difference between group A and the control group in terms of foot fault scores in any of the subsequent test sessions.In the cylinder test the forelimb use asymmetry scores of neither group A nor group B were significantly different from the control group.Group C showed marked locomotor asymmetry improvement at day 28 post-injury.There was no significantly different loss of hemispheric tissue between those groups.Conclusion After treadmill exercise for 14 consecutive days initiated at 3 or 7 days following moderate or severe TBI,rats' motor function improved.The cortical lesion volume was not associated with recovery of motor function.
