0.05). Conclusion To adept the combined test of CEA CYFRA21-1 and NSE in lung flushing fluid is more sensitivity and more valuable application in clinic.

Objective To investigate the effect of stroke unite on brain stem infarction.Methods 102 patients with brain stem infarction from Janualy 2005 to May 2009 were randomly divided into two groups:treatment group with stroke unite(n=52) and control group(n=50).Patients in treatment group were administrated stroke unite for four weeks.Cases in control group were given traditional treatment for the same time.The primary efficacy was evaluated by NIHSS(the National Institutes of Health stroke scale,NIHSS),ADL(Activities of daily living,ADL) and clinical effective.The data were analyzed by SPSS12.0 software package.The difference was significant if P

Objective To investigate the hemodynamic changes of protosystemic collaterals before and after endoscopic treatment in patients with gastroesophageal varices using 64-row multidetector computed tomograghy portal venography (MDCTPV) so as to evaluate the efficacy of endoscopic treatment in patients with or without para-esoghageal varices and with or without nonvarices portosystemic collaterals before treatment. Methods Twenty-six patients with gastroesophageal varices, who underwent endoscopic variceal ligation (EVL) for esophageal varices and endoscopic N-butyl-2-cyanoacrylate injection (EBC) for gastric varices between Jan.2007 and Dec. 2009, were enrolled. Sixty four-row MDCT was used to examine the changes of portosystemic collaterals 1 week before and 12 months after endoscopic treatment. The reconstructed images of portosystemic collaterals before and after endoscopic treatment were evaluated. Results Excellent quality of portosystemic collateral vessels on CTPV were obtained in all patients. The mean diameter of left gastric vein decreased from (6.7±1.9) mm to (5.0±1.9) mm after endoscopic treatment,with significant difference (P＜ 0.05). There was no significant difference in outcomes between patients with or without para-esoghageal varices (80% vs 72.7%, P＞0.05) and patients with or without non-varices portosystemic collaterals (82.4% vs 66.7% ,P＞0.05). Conclusions Sixty fourrow MDCTPV may provide important information for option of endoscopic treatment and prognosis.

Objective: To evaluate the clinical effects of troponin alone and troponin combining copeptin in early diagnosis of Non-ST segment elevation myocardial infarction (NSTEMI) by meta-analysis. Methods: We searched Medline, EMBASE, Cochrane, Pubmed, CNKI and Wanfang database (1995-01 to 2015-10) for the publications of troponin alone and troponin combining copeptin in early diagnosis of NSTEMI. Based on inclusion and exclusion criteria, we screened the literatures and evaluated their quality by QUADAS items. Manager 5.2 and Meta-DiSc 1.4 software were used to study the pooled sensitivity and speciifcity for troponin alone and troponin combining copeptin in NSTEMI early diagnosis, and to calculate the summary receiver operating characteristic curve (SROC) with the area under curve (AUC). Results: There were 11 articles including 1 Chinese article enrolled. For NSTEMI diagnosis, compared with troponin alone, troponin combining copeptin showed the higher sensitivity (90% vs 75%), but lower speciifcity (60% vs 87%). For SROC, both AUC were > 0.7, while the AUC of troponin combining copeptin was even lower (0.805 vs 0.891). Conclusion: Combination of troponin and copeptin had the better sensitivity for NSTEMI early diagnosis, although it with lower speciifcity while increased copeptin level might suggest the patients associated with other clinical conditions such as heart failure or stroke which were important in clinical practice.

Objective: To explore a method for macrostomia repairment, in order to to achieve better physiological and aesthetic outcomes. Methods: 23 patients with macrostomia were treated by standard procedure: including orbicularis oris reconstruction, perioral expression muscles fixation, modiolus reconstruction, commissure point shift, and " w" shape incision. Results: 22 cases obtained both static and dynamic symmetrical outcomes. One case developed asymmetrically. Conclusions The macrostomia repairment following present standard procedure, is likely to achieve both static and dynamic satisfactory outcomes, due to balanced perioral muscles.

Objective To evaluate the feasibility and efficacy of endoscopic push?radial dissection (EPRD)for benign esophageal stricture(BES). Methods Clinical data of 24 patients diagnosed as having BES who received EPRD were analyzed. The procedure and efficacy were evaluated. Results All 24 patients underwent EPRD successfully with mean operation time being 32 min(15?45 min).The mean esophageal stric?ture incision length was 3?? 2 cm (1?? 0?8?? 0 cm).No severe complications related to EPRD occurred, or trans?ferred for surgery. Patients were followed up for 1?5 months (mean 2?? 8 months). Dysphagia was relieved signif?icantly during the follow?up in 23 patients where endoscopy could go through smoothly. But dysphagia re?oc?curred in one patient 2 weeks after the operation, who underwent a second EPRD and stent implantation, then dysphagia was relieved. Conclusion EPRD is safe, feasible and effective for benign esophageal stricture.

OBJECTIVE: To evaluate image quality of female pelvic computed tomography (CT) scans reconstructed with the adaptive statistical iterative reconstruction (ASIR) technique combined with low tube-voltage and to explore the feasibility of its clinical application. MATERIALS AND METHODS: Ninety-four patients were divided into two groups. The study group used 100 kVp, and images were reconstructed with 30%, 50%, 70%, and 90% ASIR. The control group used 120 kVp, and images were reconstructed with 30% ASIR. The noise index was 15 for the study group and 11 for the control group. The CT values and noise levels of different tissues were measured. The contrast to noise ratio (CNR) was calculated. A subjective evaluation was carried out by two experienced radiologists. The CT dose index volume (CTDIvol) was recorded. RESULTS: A 44.7% reduction in CTDIvol was observed in the study group (8.18 +/- 3.58 mGy) compared with that in the control group (14.78 +/- 6.15 mGy). No significant differences were observed in the tissue noise levels and CNR values between the 70% ASIR group and the control group (p = 0.068-1.000). The subjective scores indicated that visibility of small structures, diagnostic confidence, and the overall image quality score in the 70% ASIR group was the best, and were similar to those in the control group (1.87 vs. 1.79, 1.26 vs. 1.28, and 4.53 vs. 4.57; p = 0.122-0.585). No significant difference in diagnostic accuracy was detected between the study group and the control group (42/47 vs. 43/47, p = 1.000). CONCLUSION: Low tube-voltage combined with automatic tube current modulation and 70% ASIR allowed the low CT radiation dose to be reduced by 44.7% without losing image quality on female pelvic scan.

Cadmium is one of the heavy metals with severe reproductive toxicity,whose half-life lasts 20 to 40 years.Cadmium could induce dysfunction of testis and epididymis for its significant accumulation in human testis,and the amount,motility parameters and morphology of sperm change abnormally.The adverse change could also extend to male offspring and cause the impairment of their reproductive system.There has been no clear mecha-nism of how cadmium induces dysfunction of male reproductive system,and treatment for the adverse influence on male reproductive system by cadmium has not yet been found.Therefore,this problem has been discussed in repro-ductive and environmental field for a long time.A number of previous investigations showed that cadmium could damage male fertility by followed pathways,including interfering with hormone secretion,inducing oxidative stress,activating inflammation and apoptosis,and causing energy metabolism disorder,etc.In order to enlighten new ideas for therapeutic targets of male reproductive function damage induced by cadmium,we systematically reviewed and summarized the findings of previous publications in this paper.

Objective: To evaluate the differential calretinin immunostaining in different segments of total colonic aganglionosis and its utility in the diagnosis. Methods: Nine specimens including ileum and colon segments were obtained from 9 patients with total colonic aganglionosis (TCA), from 2010 to 2016 year, in Wuhan Children′s Hospital, Tongji Medical College, Huazhong University of Science and Technology. Another 9 ganglionic specimens including the same segments from patients with non-Hirschsprung disease (non-HD) patients were collected as control. All cases were immunostained with calretinin. The patterns of calretinin immunostaining were observed, and morphometric analysis of each sample was performed by image analysis program (Image-Pro-Plus). The mean absorbance was evaluated by calculating the areas of the lamina propria occupied by the positively stained area of the calretinin at high power field. Results: The same pattern of calretinin immunostaining was seen in ganglionic ileum and ganglionic colon segments, with staining seen in intrinsic nerves fibers (INF), and in granular aggregates in the lamina propria and muscularis mucosae. There was no significant difference in the numbers of calretinin-positive INF from the ganglionic segments. In contrast, the number of calretinin-positive INF and granular aggregates in aganglionic segments were significantly lower than those in the ganglionic group (P<0.01). In the ileum transitional zone, scattered calretinin staining was observed, and the amount of calretinin-positive INF was significantly lower than those in the proximal segment of ganlionic ileum (P<0.01). Conclusions Since there is significant different expression of calretinin among the different segments from TCA, calretinin immunostaining has potential value in detecting TCA. It could be an important adjunctive method in detecting TCA in the future.

Human sparganosis is a rare parasitic disease. Pleroceroid can infiltrate brain, mammary gland and other organs, with a high misdiagnosis rate. A case of subcutaneous sparganosis disease of thigh was diagnosed and treated in the Burn, Plastic Surgery and wound Repair Department of Longyan First Hospital Affiliated of Fujian Medical University in January 2022. The patient was followed up for lipoma in other hospitals for many times with no clinical treatment. Combined with the medical history and characteristic of the mass, we also treated the mass as "lipoma" and surgical resection was performed in author’s hospital. Live worms were found intraoperatively, and finally confirmed as pleroceroid by pathology and expert consultation. No local recurrence was found in 6 months of follow-up. In order to reduce the misdiagnosis rate of the disease, the diagnosis and treatment methods were reviewed and discussed. This case may provide more clinical experience for the prevention and treatment of the disease.
