China Journal of Endoscopy 2016;22(6):68-71
Objective Taken examination of patients with colon polyps by using narrow-band imaging (NBI) com-bined with magnified endoscope, to compare the difference in the opening of the gland morphology and pathological type. Methods 110 patients of colon polyps with 147 pathological histology biopsy samples collected. Using NBI combined with magnified endoscope techniques observe pit patterns and capillary patterns identify adenomatous polyps, and compared with the results of pathological histology, then analyze the adenomatous polyp diagnosis coin-cidence rate, sensitivity and specificity. Results The pit patterns of adenomatous polyps were mostly type Ⅲ, Ⅳ andⅤ. The diagnostic coincidence rate, sensitivity and specificity was 91.16%, 88.37%, 95.08%of adenomatous polyps. It was higher than ordinary colonoscopy (80.27%, 79.07%, 81.97%), and the diagnosis accuracy of intraepithelial neoplasia and early carcinoma of NBI combined with magnified endoscope was obviously higher than that by ordi-nary endoscopy examination, the differences were statistically significant. Conclusions NBI combined with magnified endoscope was superior in observing the opening of pit patterns and capillary patterns, which was helpful to diagno-sis of tumor lesions of colon polyps.

Objective To compare the clinical effects of combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve versus spinal-epidural analgesia in total hip replacement. Methods Fifty cases of total hip replacement were randomly divided into two groups. Patients in group A received combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve,while patients in group B received spinal-epidural analgesia. Results There were no significant differences in preoperative HR, SBP,DBP and SpO2 between the groups(P > 0. 05). Compared with pre-anesthesia data,HR,SBP,DBP in group A were significantly lower during the anesthesia(P < 0. 05). In group B,there were no significant changes in HR,SBP,DBP and SpO2 during the anesthesia( P > 0. 05). Patients′ heart rate in group A showed significant changes compared with that in group B. The differences in HR,SBP and DBP between group A and B at the same time points were significant(P < 0. 05). Superior rate of anesthesia in group B is higher than that in group A(P < 0. 05). Conclusion Combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve has limited influence on the circulatory and respiratory systems,which can be used for total hip replacement.

OBJECTIVETo analyze the early expression differences of lung tissue proteins in rats exposed to silica using comparative proteomics method, to explore the effects of Chinese traditional medicine (Gymnadenia conopse alcohol extract, GcAE) on silicosis (50 mg/ml).
METHODSAdult male Wistar rats were randomly divided into silica-treated group and GcAE-treated group, four rats a group. The rats were exposed to silica by intratracheal (IT) instillation of 1 ml silica suspension for 24 h. After exposure, the rats in GcAE-treated group were intragastric administration with 0.8 ml GcAE (0.8 ml/100 g a day) and the rats in silica-treated group were intragastric administration with 2 ml sterilized saline a day for 14 days. Then all rats were sacrificed and lung tissues were collected. The total proteins were separated by means of two-dimensional gel electrophoresis (2-DE) and the differentially expressed proteins were identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Western blotting was used to validate the expression of certain candidate proteins in lung tissues.
RESULTSObvious pathological changes of lung could be observed in silica-treated group, such as the thicken of interalveolar septum, which was infiltrated with lymphocytes, macrophages and a few neutrophils with the proliferation of fibroblasts and smooth muscle cells. The accumulation of collagen, the destruction of alveolus structure and the more dotted fibrosis or granuloma could also be found. However, the pathological changes of lung in GcAE-treated group were lighter than those of silica-treated group. Thirty three differentially expressed proteins were identified, including cathepsin D precursor, peroxiredoxin-1 (Prx-1) and SEC14-like protein 3. Compared with silica-treated group, cathepsin D precursor and Prx-1 were significantly downregulated in GcAE-treated group, and SEC14-like protein 3 was significantly upregulated (P < 0.01). The results of western blot indicated that the expression level of Prx-1 in GcAE-treated group was 0.26 ± 0.02, which was significantly lower than that (0.35 ± 0.04) in silica-treated group (P < 0.01).
CONCLUSIONGcAE may inhibit the progress of silicosis in the early period and cathepsin D precursor, SEC14-like protein 3 and Prx-1 may participate in this process.

Objective:
To investigate the prevalence and influencing factors of adolescent depression symptoms in Zhejiang, so as to provide reference for improving their mental health.
Methods:
The middle school and university students in 11 cities of Zhejiang Province were selected by stratified cluster random sampling method. The depression symptoms of the adolescents were assessed by Center for Epidemiological Survey-Depression Scale ( CES-D ) and the influencing factors were analyzed by multivariate logistic regression model.
Results:
A total of 25 855 students were investigated, and 25 614 ( 99.07% ) valid questionnaires were collected. The detection rate of depressive symptoms was 26.86%(6 879 cases). The detection rate of depressive symptoms in girls was 29.75%, which was higher than 24.12% in boys ( P<0.05). The detection rate of depressive symptoms in high school students was 31.74%, the highest compared with other grades. The multivariate regression analysis showed that female students ( OR=1.690, 95%CI: 1.592-1.794 ), resident students ( OR=1.071, 95%CI: 1.010-1.137 ) , internet addiction ( OR=2.948, 95%CI: 2.527-3.439 ) , attempt smoking ( OR=1.516, 95%CI: 1.359-1.690 ), drinking ( OR=1.624, 95%CI: 1.525-1.729 ), bullied in the past 30 days ( OR=3.143, 95%CI: 2.938-3.363 and having serious injuries within a year ( OR=1.369, 95%CI: 1.263-1.543 ) were associated with adolescents who had depressive symptoms.
Conclusions
The detection rate of depressive symptoms is relative 26.86% among adolescents of Zhejiang Province. The students who are female, live on campus, have internet addiction, have been bullied or seriously injured, smoke and drink are more likely to have depressive symptoms.

Spinal muscular atrophy (SMA) is a group of neuromuscular disorders, caused by degeneration of the motor neurons in the anterior horn of the spinal cord, with prevalence of about 1 in 6000 to 1 in 10000 in newborn. The gene carrying frequency is about 1 in 40 to 1 in 50 all over the world. SMA is one of the most common autosomal recessive diseases causing infant death. SMA mainly refers to SMN1 dependent caused by SMN1 gene mutations. Noninvasiveness and specificity make genetic testing a recommended method for diagnosis of SMA. In addition to conventional methods such as neural nutrition, muscle exercise, etc., there is no specific treatment for SMA up to now. Nevertheless, HDAC inhibitors deserve attention as they are the only drugs completed Phase Ⅲ clinical trials to date. Furthermore, other ways as small-molecule SMN enhancers, induced pluripotent stem cell (iPSC), antisense oligonucleotides to correct SMN2 splicing, etc, were still on the way of in vitro stage at present.

OBJECTIVETo observe the efficacy of acupuncture on pain after replantation of severed finger.
METHODSA total of 80 patients who underwent replantation of severed finger were randomly divided into an observation group and a control group, 40 cases in each one. The patients in the control group were treated with postoperative routine care of hand surgery, while patients in the observation group, based on the regular treatment, were treated with acupuncture within first 72 h of surgery. The health side of Yanglingquan (GB 34), Xuehai (SP 10), Hegu (LI 4), Houxi (SI 3) were selected and the needles were retained for 30 min. The acupuncture was given for 6 times. The evaluation was performed by using visual analogue scale (VAS) 2 h, 4 h, 6 h, 12 h, 24 h, 48 h and 72 h after surgery. The use of analgesics after surgery was recorded in the two groups, and the blood supply and survival rate of severed finger were evaluated.
RESULTSCompared between the two groups, the VAS 4 h, 6 h, 12 h, 24 h and 48 h after surgery in the observation group was lower than that in the control group (all P<0. 05); the use frequency of analgesics in the observation group was lower than that in the control group (P<0. 05); the abnormality rate of blood supply in the observation group was lower than that in the control group (P<0. 05).
CONCLUSIONAcupuncture can significantly relieve postoperative pain of replantation of severed finger, and reduce the occurrence rate of abnormal blood supply, which is worthy of clinical promotion.
