Objective To explore the effect of psychological nursing on patients with condyloma acuminatum. Methods 324 patients with condyloma acuminatum were randomly divided into the intervention group and the control group with 162 cases in each group.All patients were given carbon dioxide laser therapy,based upon this,the control group was given routine nursing,and the intervention group was additionally given psychological nursing.The anxiety and depression score and the treatment effect were compared between the two groups. Results After one-month treatment,the scores of SAS,SDS in the intervention group declined obviously compared wilt those of pre-treatment and the control group.The cure rate and the recurrce rate in the intervention group were 86.4％ and 13.6％,significantly better than those of the control group. Conclusions Psychological nursing can remit the anxiety and depression emotion of patients with concdylouna acuminatum,improve the cure rare and reduce the recurrence rate of condyloma acuminatum.

With development of bio-technique, more and more proteins were applied as clinical approaches. However, the protein homogeneity, especially the N-glycosylation limited the further research and application of these protein drugs. The analysis method for N-glycans is believed to be critical in protein drugs development. To enhance the N-glycans isolation efficiency and accelerate the pretreatment, a new strategy was built on ultrafiltration-devices. New methods increased the isolation efficiency of N-glycans containing N-acetylglucosa mine with 10%-20%. The degrading of N-glycans containing sialic acids was also minimized with this method. 20%-100% more N-glycans with sialic acids were isolated. The pretreatment was finished within 30 min. Coupled with HPLC-HRMS, an effective and reliable strategy designed for protein drugs N-glycans analysis were developed.

Objective To investigate the therapeutic effect of oxiracetam combined with dexamethasone for treatment of patients with severe acute carbon monoxide poisoning (ACOP).Methods Eighty-seven patients with severe ACOP admitted to Affiliated Hospital of Xuzhou Medical University from January 2013 to July 2016 were enrolled, and they were divided into observation group (47 cases) and control group (30 cases) according to random number table method. The two groups were given conventional nerve nutrition, hyperbaric oxygen and symptomatic treatment, while in the observationgroup, on the basis of conventional treatment the patients received intravenous drip of dexamethasone 5 mg (with addition of normal saline 100 mL), once a day for consecutive 3 days, and intravenous drip of oxiracetam 3.0 g plus 100 mL normal saline, once a day for consecutive 7 days. The changes of mini-mental state examination (MMSE), Barthel index and Glasgow coma scale (GCS) were observed after discharge for 30 days, and the differences of the incidence of delayed encephalopathy after acute carbon monoxide poisoning (DEACMP) and hospitalization time between the two groups were compared.Results After treatment the MMSE and GCS scores of the two groups were higher than those before treatment, and the Barthel score was lower than that before onset. After discharge for 30 days, MMSE score (26.93±2.92 vs. 24.20±6.82), GCS (14.41±1.32 vs. 13.98±2.13), Barthel (94.78±12.62 vs. 85.25±19.57) of the observation group were significantly higher than those of control group, and the incidence of DEACMP was obviously lower than that in the control group [8.5% (4/47) to 17.5% (7/40)], the differences between the two groups being statistically significant (allP < 0.05); the hospitalizationtime of the observation group was shorter than that of the control group (days: 10.81±5.49 vs. 13.05±6.84), but there was no significant difference between the two groups (P > 0.05).Conclusion Early combined application of oxiracetam and dexamethasone can significantly improve the cognition and self-care abilities and reduce the incidence of DEACMP in patients with severe ACOP after discharge for 30 days.

Objective To investigate the abnormal expression of microRNA (miRNA)-25 in the serum of gastric cancer patients and its clinical significance. Methods In Xijing Hospital of Digestive Diseases,Fourth Military Medical University,86 gastric cancer patients with operation and completed follow-up data,70 gastric adenoma patients and 80 healthy controls were selected as study objects.Total RNA was isolated from the serum. After the stable and sensitive miRNA-25 absolute quantity detection method established,the serum levels of miRNA-25 in gastric carcinoma patients,gastric adenoma patients and healthy controls were tested according to this method. The expression differences of miRNA-25 in the serum of patients with gastric cancer and gastric adenoma and healthy controls were analyzed with statistic analysis,and the correlation between miRNA-25 expression level and clinic pathological features of gastric cancer was also analyzed. Results The expression level of miRNA-25 in the serum of gastric cancer patients (135. 6 fmol/μg total RNA) was significantly higher than that of gastric adenoma patients (67. 7 fmol/μg total RNA) and healthy controls (62. 2 fmol/μg total RNA)(P＜0. 01). The receiver operating characterisstic curve of miRNA-25 indicated that serum miRNA-25 with good specificity and sensitivity in gastric cancer diagnosis (AUC=0. 827). The serum level of miRNA-25 in gastric cancer patients with lymph node metastasis [(148. 3±10. 2) fmol/μg total RNA] or clinicopathological stage Ⅲ /Ⅳ patients [(146. 7±9.5) fmol/μg total RNA] was significantly higher than that of gastric cancer patients without lymph node metastasis [(120. 3±10. 1)fmol/μg total RNA] or clinicopathological stage Ⅰ/Ⅱpatients [(119. 4±12. 2) fmol/μg total RNA] (P＜0.05). The correlation statistical analysis result indicated that there was no significant difference in survival period between serum miRNA-25 highly expressed and lowly expressed gastric cancer patients (P＞0. 05).Conclusion Serum miRNA-25 testing maybe helpful in diagnosis and prognosis of gastric cancer.

OBJECTIVETo investigate the effect of propofol on brain regions at different sedation levels and the association between changes in brain region activity and loss of consciousness using blood oxygen level-dependent functional magnetic resonance imaging (BOLD-fMRI) and bispectral index (BIS) monitoring.

METHODSForty-eight participants were enrolled at Peking Union Medical College Hospital from October 2011 to March 2012 and randomly assigned to a mild or a deep sedation group using computer- generated random numbers. Preliminary tests were performed a week prior to scanning to determine target effect site concentrations based on BIS and concomitant Observer's Assessment of Alertness/Sedation scores while under propofol. Within one week of the preliminary tests where propofol dose-response was established, BOLD-fMRI was conducted to examine brain activation with the subject awake, and with propofol infusion at the sedation level.

RESULTSMild propofol sedation inhibited left inferior parietal lobe activation. Deep sedation inhibited activation of the left insula, left superior temporal gyrus, and right middle temporal gyrus. Compared with mild sedation, deep propofol sedation inhibited activation of the left thalamus, precentral gyrus, anterior cingulate, and right basal nuclei.

CONCLUSIONMild and deep propofol sedation are associated with inhibition of different brain regions, possibly explaining differences in the respective loss of consciousness processes.

AIM: To investigate the characteristics and surgical management of retinal detachment (RD) after laser-assisted in situ keratomileusis (LASIK) in myopia.METHODS: Documents of patients with RD observed in 18342 eyes (9 598 patients) who underwent LASIK were retrospectively reviewed. None of the patients had history of corneal or other diseases before LASIK and preoperative fundus examination was performed. Patients were followed for a mean of 20 months and the clinical features of the eyes which developed RD after LASIK were investigated.RESULTS: Six patients including 2 males and 4 females developed RD, and the incidence of RD after LASIK was 0.33‰. Mean pre-LASIK myopia in these 6 eyes was 9.33D.None of these eyes had prophylactic treatment history of any retinal lesions. Mean time interval between LASIK and RD development was 9.2 months. All RDs happened spontaneously and were managed with vitrectomy and other techniques.Retinal reattachment was achieved at the first retinal detachment surgery in all 6 eyes (100%) at mean follow-up of 9.3months.CONCLUSION: RD after LASIK is not common. The study suggests no cause-effect relationship between RD and LASIK procedure in myopic eyes. However, clinicians should still be aware of retinal pathology in patients undergoing LASIK.

AIM: To assess the efficacy and safety of prophylactic laser photocoagulation for retinal breaks before laser in situ keratomileusis (LASIK) in myopic eyes.METHODS: From April 2000 to April 2004, totally 1 845 eyes ( 1 233 patients ) requesting LASIK had a fundus examination with indirect ophthalmoscopy before the surgery. They were divided into two groups according to the presence (Group 1) or absence of retinal breaks (Group 2). All patients with retinal breaks, though they were asymptomatic, underwent prophylactic laser photocoagulation to seal the breaks before LASIK.RESULTS: Patient age ranged from 18 to 43 ( 25.3±5.7) yaers old. Mean preoperative spherical equivalent refraction (PSER) was -7.44± 2.13 D (range, -1.50 to -14.50 D). Retinal breaks were identified and treated in 37eyes (2.05%) of 32 patients;1 808 eyes of 1 201 patients had no retinal breaks. No statistical difference was found in age ( P ＞0.05) or gender (P ＞0.05) between the two groups. Significant difference of PSER was noted between Group 1 (-9.41± 4.15D) and Group 2 (-7.52±3.71D) (P＜0.05). During a mean 14mo follow-up, none of the patients developed retinal detachment.CONCLUSION: The efficacy and safety of prophylactic laser photocoagulation for retinal breaks was confirmed.Retinal breaks should be identified and treated by photocoagulation in eyes before LASIK for myopia.

Objective To explore the effect of ginseng co?enzyme Q10 suncream on the skin damage caused by ul?traviolet ( UV) radiation in mice. Methods 36 mice were randomly assigned to four groups. The mice were shaved on the back and the left untreated side was taken as control group, or was treated with UV as model group. Before treated with UV, the mice were painted with suncream containing ginseng co?enzyme Q10 , or octyl methoxycinnamate as positive con?trols. The mice were treated for 8 weeks. At the end of the experiment, blood samples of all mice were collected from the eyes, then subjected to cell counting or biochemical measurements, and skin samples were cut for pathological examina?tion. Results Compared with the control group, there was a significant increase in white blood cell counts ( P<0?05 ) and MDA content ( P<0?05 ) , and declined serum levels of SOD ( P <0?05 ) and GSH?Px ( P <0?05 ) in the model group, and the skin was rough and wrinkled with stratum corneum exfoliation. Compared with the model group, the mice of ginseng co?enzyme Q10 suncream group had significantly lower white blood cell count ( P<0?05 ) and MDA content ( P<0?05), and increased serum levels of T?SOD(P<0?05) and red blood cell counts (P<0?05). The skin had no rough? ness and wrinkles and without stratum corneum exfoliation. Compared with the model group, the positive control group showed significantly decreased white blood cell count (P<0?05) and MDA content (P<0?05), and increased serum lev?els of GSH?Px(P<0?05). The skin had no roughness and wrinkles and no stratum corneum exfoliation. However, there was no significant difference between the ginseng co?enzyme Q10 suncream group and positive control group. Conclusions Ginseng co?enzyme Q10 suncream shows satisfactory preventive effects on the UV radiation?induced skin damage in mice, similar to the preventive effects of the octyl methoxycinnamate?containing sunsream.
