Objective To explore the causes of nosocomial infections in ICU as to provide scientific evidence for the corresponding intervention measures.Methods The retrospective survey was used to investigate and analyze the incidence of nosocomial infections in ICU from 2013 to 2014.Results The total of 1225 patients investigated,182 patients suffered from nosocomial infections and the nosocomial infections rate was 14.86％.The etiology of ICU specimen was 95.22％.Gram negative bacilli,Gram positive bacteria and fungi,which accounted for 69.16％,18.22％ and 12.62％ respectively.The main infection site were respiratory tract,blood and urinary tract,which accounted for 70.43％,11.30％ and 4.78％ respectively.Conclusion The hospital infection rate of ICU in our hospital is kept the same level of the hospital in the same area.Etiology specimens rate comply with national standards.Main pathogens are gram negative bacilli,and the main site of infection is respiratory.

Objective To study the incidence and etiology of knee pain in patients with tibial shaft fracture after intramedullary nailing treatment. Methods From Jan 1997 to Dec 2002, 1332 patients with tibial shaft fracture were treated with intramedullary nailing in our hospital. Their clinical data were retrospectively studied. All the patients were followed up at least once after fracture healing, and the average clinical follow up duration was 27 months. Results 409 of the 1332 cases experienced knee pain. 31.9 percent of the patients treated with transtendinous nailing reported anterior knee pain, and 28.9 percent of the patients treated with paratendinous nailing reported knee pain. Conclusion Compared with the transpatellar tendon approach, the paratendinous approach for nail insertion does not reduce the incidence of anterior knee pain.

OBJECTIVETo compare postoperative blood loss under different negative pressures of drainage after total hip arthroplasty for the treatment of femoral neck fractures.

METHODSFrom January 1st to December 30th 2013, 74 patients with femoral neck fractures treated with total hip arthroplasty were randomly divided into two groups: high negative pressure drainage group and low negative pressure drainage group. In high negative pressure drainage group, there were 34 cases including 10 males and 24 females, with a mean age of (75.94 ± 9.02) years old, and the patients were treated with 60 kPa negative pressure of drainage. In the low negative pressure drainage group, there were 40 cases including 13 males and 27 females, with an average age of (74.93 ± 8.90) years old, and the patients were treated with 30 kPa negative pressure of drainage. The amount of total drainage, total blood loss, and hemoglobin change were compared between these two groups.

RESULTSAll the patients got primary healing without infections. In high negative pressure drainage group,the change of hemoglobin was (41.74 ± 15.69) g/L, total blood loss was (1,217.73 ± 459.50) ml and the drainage volume was (312.94 ± 103.44) ml; while in low negative pressure drainage group,the results were (34.90 ± 12.90) g/L, (904.01 ± 381.58) ml and (129.25 ± 44.25) ml separately. All the results in high negative pressure drainage group were higher than those in the other group. Three days after operation, the change of hemoglobin was (46.00 ± 13.29) g/L and total blood loss was (1,304.72 ± 421.75) ml; while in low negative pressure drainage group, the changes of hemoglobin was (43.87 ± 11.39) g/L and total blood loss was (1,196.78 ± 344.20) ml; there were no statistically significant differences between two groups.

CONCLUSIONWhen placing drainage devices after total hip arthroplasty for the treatment of femoral neck fractures, the level of negative pressure should be chosen according to preoperative level of hemoglobin and HCT in patients. For old patients with femoral neck fracture, low negative pressure is more suitable.

Objective To explore the effect of leg massage during operation on deep venous thrombosis(DVT)in patients of vascular surgery department.Methods Ninety-four DVT patients were randomized into experiment group and control group according to the computer-generated numbers ,46 cases in the latter and 48 in the former.The routine care measures were applied in the control group, while intraoperative leg massage was used in the observation group.The two groups were compared in terms of curative effect and the incidence of DVT.Result The incidences of DVT in the experiment group and the control one were 2.08%(1/48)and 15.22%(7/46)respectively, showing significant difference between them(P<0.05).Conclusion The intraoperative lag massage are significant in the reduction of DVT incidences after operation.

AIM: To investigate the expression of microRNA-375 (miR-375) in hepatocellular carcinoma (HCC) and to analyze the target genes and signaling pathways regulated by miR-375.METHODS: The expression of miR-375 was examined at tissue microarray of HCC by in situ hybridization.The whole human genome chip and bioinforma-tics analysis were applied to screen out the differential expression genes and signaling pathways in 4 HCC cell lines trans-fected with miR-375 mimic.RESULTS:In situ hybridization showed the expression of miR-375 in HCC tissues were obvi-ously higher than that in tumor-adjacent tissues (P<0.05).There were 20 co-upregulated genes and 17 co-downregulated genes in all 4 cell lines.Bioinformatic analysis showed that there were 54 signaling pathways related to up-regulated genes and 48 signaling pathways related to down-regulated genes in all 4 cell lines.CONCLUSION: miR-375 may play a key role in the pathological process of HCC.The bioinformatic analysis is able to screen the target genes and signaling pathways regulated by miR-375 and to provide an explicit direction for further mechanism research on HCC.

Objective To investigate neuroprotective effect of AM-36 on secondary brain injury following traumatic brain injury(TBI)in rats.Methods A total of 38 male Sprague-Dawley rats were divided into an experimental group,a control group and a sham operation group,then sustained to moder- ate TBI.AM-36(0.1 ml/100 g)was administered intraperitoneally in the experimental group and isoton- ic saline solution was administered intraperitoneally in the control and the sham operation groups at 30 mi- nutes,24 and 48 hours after TBI,respectively.The brain water content was determined at 24 hours after TBI.Rats were sacrificed by decapitation at 24 hours or one week after TBI for observing histological changes in peripheral cortex,thalamus and hippocampus by means of Hematoxylin and Eosin staining and Fluoro-Jade(F-J)staining.Results The brain water content of bilateral hemispheres 24 hours after TBI in the experimental group was significantly decreased,compared to that of the control group.Histo- logical examination revealed less degenerating neurons(F-J positive neurons)in the cortex,thalamus, CAI and CA3 of the hippocampus in AM-36 treated rats 24 hours and one week after injury(P＜0.05). Conclusion Systemic administration of AM-36 at the early stage after TBI can decrease brain water content and exert neuroprotective effect on TBI.F-J staining can be used for histopathologic quantitation of neuronal damage,for it can accurately exhibit pathologic changes following TBI induced by fluid per- cussion.

There is a contradiction between image denoising and protection of the useful information in the image. To deal with this contradiction, we use the approach of mathematical morphology. In this paper, we expound the method and effectivity of mathmatical morphology in image processing. Based on it, an improved and fast image denoising algorithm is proposed and some experiments have been made to show that this algorithm is simple, effective and feasible.

OBJECTIVETo explore the effect of immune-enhanced enteral nutrition (IEN) together with recombined human growth hormone (rhGH) on patients after total gastrectomy.

METHODSForty-eight patients after total gastrectomy were randomly divided into EN group (n=16), IEN group (n=16) and IEN+ rhGH(n=16) group. Nitrogen balance, nutritional status, immune function and lassitude degree were compared among 3 groups.

RESULTSIEN+rhGH group had better efficacy as compared to EN and IEN group in improving postoperative nutritional status, immune function, nitrogen balance and lassitude degree, and recovered to normal level after 7 days. All the indexes of IEN+rhGH group except CD8 were improved significantly on the 10th day after operation as compared to those of EN group[total protein(66.8 +/- 2.0)g/L vs (65.8 +/- 0.9)g/L, CD3(66.1 +/- 6.3)% vs (60.5 +/- 5.6)%, Christensen score (4.6 +/- 0.9) vs (6.3 +/- 0.9), all P<0.05].

CONCLUSIONEarly application of IEN combined with rhGH plays an effective role in improving protein metabolism and immune function for patients after total gastrectomy in short period.

OBJECTIVETo compare the efficacy and feasibility of neoadjuvant chemoradiotherapy with docetaxel plus cisplatin or with cisplatin plus fluorouracil in the treatment of local advanced esophageal squamous cell carcinoma.

METHODSA total of 154 cases in the stage of cT3N0-1M0 were randomly assigned to two arms. The arm A received 2 cycles of doctaxel 75 mg/m(2) plus cisplatin 25 mg/m(2) d1-3 and 40 Gy of radiation therapy, and the arm B received 2 cycles of cisplatin 25 mg/m(2) d1-3 plus fluorouracil 600 mg/m(2) d1 ∼ 5 and 40 Gy of radiation therapy. The surgery was performed 3 - 4 weeks later.

RESULTSGrade 3/4 toxicities occurred in 53.2% of the patients in arm A and in 36.4% of the patients in arm B (P = 0.035). Neutropenia occurred in 20.7% of the patients in arm A and 5.6% of the patients in arm B (P = 0.004). Nine patients aborted surgery due to tumor progression. 71 patients underwent resection in 73 cases of the arm A and 69 patients underwent complete resection, 70 patients underwent resection in 72 cases and 70 complete resection of the arm B, respectively (P > 0.05). No mortality was noted. The overall complication rate was similar in the two arms (21.9% vs. 23.6%). Pathological complete response was achieved in 27 patients (35.1%) in the arm A and 16 patients (20.8%) in the arm B (P = 0.048).

CONCLUSIONSNeoadjuvant chemoradiotherapy with docetaxel plus cisplatin can be well tolerated and achieves a higher pathological complete response rate than with cisplatin plus fluorouracil.
