BackgroundIn an ideal eye there would be no light scattering at all,but the eye media is not optically ideal.Intraocular straylight causes a veil of light and reduction in the contrast of the retinal image and thus decrease the quality of vision.ObjectiveThe present study was to investigate the repeatability and reproducibility of C-Quant straylight meter( Oculus,Germany)in measuring retinal straylight of myopia and post-laser in situ keratomileusis(LASIK) corneas.MethodsThis is a prospective research.The consecutive 35 eyes of 21 myopic patients and 34 eyes of 22 patients who received LASIK were included in this trail.Retinal straylight was measured for 7 times at a period of time and analyzed quantificational to evaluate the repeatability of measurement.Thirty-eight eyes of 19 patients were measured again at 3-7 days for 3 times at a period of time to assess the reproducibility of C-Quant straylight meter.The mean standard difference (SD) and coefficient of variation (CV) were used as the credibility evaluation.This clinical study complied with Helsinki Declaration and the informed consent was obtained prior to the medical procedure.ResultsThe straylight Log(s) of 7 times measurement were all less than 0.95.The mean Log(s) were 0.92±0.12 and 0.93±0.17 respectively in myopia group and post-LASIK group,without statistically significant differences among 7 times measurement( F=0.335,P=0.812;F=1.000,P=0.409).The mean SD for the 7 times measurement was 0.07 Log units.SD and CV increased with the number of measurements.The differences of mean SD and CV between 3 times result and 6 times result were significant different (t =-2.080,P =0.045;t =-2.190,P =0.035 ).No difference was found between different time periods( t =-0.531,P=0.598 ).The difference of the results between two measurements from the same patient was 0.013.ConclusionsC-Quant is a noncontact,noninvade,rapid and convenient method for the measurement of straylight in myopia and post-LASIK eyes due to the high repeatability and reproducibility.

BACKGROUND: Good neurological outcome after cardiac arrest (CA) is hard to achieve for clinicians. Experimental and clinical evidence suggests that therapeutic mild hypothermia is beneficial. This study aimed to assess the effectiveness and safety of therapeutic mild hypothermia in patients successfully resuscitated from CA using a meta-analysis. METHODS: We searched the MEDLINE (1966 to April 2012), OVID (1980 to April 2012), EMBASE (1980 to April 2012), Chinese bio-medical literature & retrieval system (CBM) (1978 to April 2012), Chinese medical current contents (CMCC) (1995 to April 2012), and Chinese medical academic conference (CMAC) (1994 to April 2012). Studies were included if 1) the study design was a randomized controlled trial (RCT); 2) the study population included patients successfully resuscitated from CA, and received either standard post-resuscitation care with normothermia or mild hypothermia;3) the study provided data on good neurologic outcome and survival to hospital discharge. Relative risk (RR) and 95% confidence interval (CI) were used to pool the effect. RESULTS: The study included four RCTs with a total of 417 patients successfully resuscitated from CA. Compared to standard post-resuscitation care with normothermia, patients in the hypothermia group were more likely to have good neurologic outcome (RR=1.43, 95% CI 1.14–1.80, P=0.002) and were more likely to survive to hospital discharge (RR=1.32, 95% CI 1.08–1.63, P=0.008). There was no significant difference in adverse events between the normothermia and hypothermia groups (P>0.05), nor heterogeneity and publication bias. CONCLUSION: Therapeutic mild hypothermia improves neurologic outcome and survival in patients successfully resuscitated from CA.

Objective To evaluate the use of transfer statements in inhouse transport of critical patients.Methods By means of continuous enrollment,123 critical patients were enrolled as a control group for conventional transport,and 111 such patients were enrolled as an observation group for transport using the transfer statement.Then the incidence of adverse events,transport during and nurse-nurse collaboration level of the two groups were compared.Results In the control group,its incidence of adverse events was 13.8%,the mean transport during was(19.5 ± 8.4)minutes,and the mean score for nurse-nurse collaboration level was ( 101.87 ± 7.13 ).In the observation group,its incidence of adverse events was 5.4%,the mean transport during was(13.5 ± 5.4)minutes,and the mean score for nurse-nurse collaboration level was(106.15 ± 8.86).Implementing the transfer statement has cut back the incidence of adverse events (P<0.05)and the transport duration significantly(t=3.833,P<0.01),while improving the level of nurse-nurse cooperation significantly(t= -4.261,P<0.05).Conclusions The transfer statement can increase the safety of patient transport,promote organization and coordination of nurses,and improve the efficiency of transport.

Objective To analyze relevant clinical and dosimetric factors associated with radiation pneumonitis in patients with stage Ⅲ non-small cell lung cancer after they received radical radiotherapy.Methods A total of 126 patients with stage Ⅲ non-small cell lung cancer who received precision radiotherapy in Peking University Cancer Hospital were analyzed from January 2013 to December 2014.Data were collected including various clinical factors (including sex,age,histological type,tumor location,history of diabetes,history of hypertension,history of smoking,the season patients received treatment,ECOG performance status before treatment,chemotherapy before radiotherapy,concurrent chemotherapy and the classification of radiation pneumonitis),as well as related dosimetric parameters [including GTV,lung volume (LV),bilateral V5,V10,V20,V30 and MLD].SPSS 19.0 software was used to analyze the relation between correlation factors and radiation pneumonitis (RP≥2).Results Among the patients,31 cases (24.6％) had occurrance of radiation pneumonitis ≥ 2.Univariate analysis showed that age,ECOG performance status before treatment,concurrent chemotherapy and GTV/LV ratio were significantly correlated with RP ≥ 2 (R =0.157-0.222,P ＜ 0.05).Further multivariate Logistic regression showed that age,concurrent chemotherapy and GTV/LV ratio were significantly correlated (Wald =4.754,6.422,14.79,P ＜ 0.05).Conclusions In patients with stage Ⅲ non-small cell lung cancer after receiving thoracic radical radiotherapy,increasing age and GTV/LV ratio≥3.2％ are risk factors of RP≥2.The concurrent chemotherapy with low-dose paclitaxel might also increase the risk of RP≥2.

Objective To investigate sonographic patterns of intussusception with relationship to pathologic change,reducibility and ischemia. Methods Twenty-one intussusceptions were surgically induced in rabbits,and in vitro ultrasonography was compared with the corresponding pathologic changes. Ultrasonography findings in 25 cases of pediatric intussusception confirmed by means of air enema examination or surgery were analyzed. Results The results of animal experiment showed that:①when no ischemia of intestine loop occurred,axial images of intussusception showed a "target-like" mass,if ischmia of intestine loop appeared,it demonstrated as a "doughnut-like" mass; ②bowel unviability and reducibility seemed clearly related to the thickness of hypoechoic external rim of the "doughnut" mass and blood flow on color Doppler flow images (CDFI) in intussusceptum. When the flow on CDFI in intussusception was absent,the possibility of bowel necrosis was increased( P

Objective To study the effects of acupuncture at myofascial trigger points on spastic foot drop and inversion after stroke. Methods From May, 2014 to May, 2016, 50 stroke patients were randomly divided into control group (n=25) and observation group (n=25). Both groups accepted routine rehabilitation, while the observation group accepted acupuncture at myofascial trigger points per day in addi-tion. They were assessed with Visual Analogue Scale (VAS) of pain, modified Ashworth Scale (MAS), range of motion (ROM) of ankle, sim-plified Fugl-Meyer Assessment (FMA) for lower limbs and maximum walking speed (MWS) in ten metres before and six weeks after treat-ment. Results The scores of VAS, MAS, and FMA, the ROM of ankle, and MWS improved after treatment (t>6.845, P<0.001), and im-proved more in the observation group than in the control group (t>5.586, P<0.001). Conclusion Acupuncture at myofascial trigger points can release spasm to reduce foot drop and inversion in patients with stroke.
