Background Aspheric intraocular lens (IOL) is designed to reduce the spherical aberration of the eye after cataract surgery and to obtain better visual quality.However,the selection of a personalized aspheric IOL is a problem to be solved.Objective This study was to compare the wavefront aberration and quality of vision of patients between the implantation of negative spherical aberration IOL and non-aberration IOL,and to investigate the relationship between corneal Q values and postoperative spherical aberration.Methods One hundred and four eyes of 90 patients with age-related cataract were randomized into two groups.Fifty-two eyes of 46 patients who received a Tecnis Z9001 IOL implantation were assigned as the negative spherical aberration IOL group and 52 eyes of 44 patients who received Akreos AO IOL without aberration were assigned as the non-aberration IOL group.The preoperative corneal Q values were measured and the mean Q value(Q)was computed.Then the patients in the two groups were further divided into 2 subgroups,respectively,based on their Q values were over or below (Q）.The corneal Q values,root mean square(RMS) of ocular spherical aberration,coma and total higher-order aberrations(HOAs) for 5 mm diameter pupil,scotopic contrast sensitivity with or without glare at 6 mm pupil diameter were measured 3 months after surgery.Results The pre-and post-operative corneal Q values were insignificantly changed (t =1.447,P =0.151).The spherical aberration in the negative spherical aberration IOL group was(0.059-±0.047)μm,and that in the non-aberration IOL group was(0.110±0.066)μm,with a statistically significant difference between them (t =-4.567,P=0.000).Scotopic contrast sensitivities at intermediate and high frequencies were significantly better in the negative spherical aberration IOL group than in the non-aberration IOL group (t =2.495,t =2.359,P ＜ 0.05).There was no significant difference in coma and HOAs between the two groups after operation (P ＞ 0.05).Weak positive correlations were seen between the pre-and post-operative corneal Q values and spherical aberration in the two groups(r=0.277,0.292,0.285,0.325,all at P＜0.05).However,no significant differences were found in spherical aberration,contrast sensitivity and scotopic contrast sensitivity between the different subgroups (P ＞ 0.05).Conclusions Negative spherical aberration IOL has lower spherical aberration and better scotopic contrast sensitivity than non-aberration IOL.The results suggest that it may be not enough to choose the corneal Q value only as the single reference criterion for selection of aspheric IOL.

To explore effects of homologous sclera implantation for treating eyelid cicatricial entropion after burns.Fifteen patients (15 eyes) with cicatricial entropion after burns were operated under microscope with homologous sclera graft in the eyelid.The tarsus was separated fully from the palpebral margin of the musculus orbicularis oculi,with deleted area of the conjunctiva for implantation,and homologous sclera graft was taken on the implant bed and sutured together.The implant and the bed were well cured together during postoperative follow-up,with less than 10 percent of constriction of the implant,indicating obvious effect of homologous sclera graft for treating the eyelid cicatricial entropion after burns.

Objective To develop a method of quality control for fingerprints of Xinshu Oral Liquid. Methods Based on electrophoregram of ten batches of genuine Radix Angelicae Sinensis (RAS), ten batches of genuine Rhizoma Chuanxiong (RC), and ten batches of genuine Flos Carthami (FC) by high performance capillary electrophoresis (HPCE) to compare the fingerprints between Xinshu Oral Liquid and the genuine medicinal herbs, single herb decoction, nagetive control herb solution, respectively. The fingerprint assignment was made by comparing the UV spectra and relative migration time. Results To compare the fingerprints of ten samples from different batches and single herb, the correlation of peaks between fingerprings was found. Finally the standard fingerprints and the method of quality control were established. Conclusion Based on the fingerprints of ten batches of prearations, an average electro-phoregram was used as the standard fingerprint. There are 27 “common peaks” in the fingerprint, among them 14 from RAS, ten from RC (in which seven are commnon) and nine from FC.

Objective: To build a mouse tumor model with a manufactured surgical wound representing acute inflammation, and to evaluate the relationship between acute inflammation or wound healing and the process of tumor growth. Then to observe the impact of IFN-γ/TGF-β on tumor growth. Methods: Male C57BL mice of six weeks were used and divided into the experiment group and the control group. The B16F10 mela-noma cell suspension was injected into the left groin area of each mouse. A wound measured 1 cm in diame-ter was built on the opposite side of bodies in the experiment group when tumor volume was about 0.5 cm~3.The expression of IFN-γ/TGF-β in blood serum and tumor tissues were examined by ELISA. In order to fur-ther confirm the effect of TGF-β on tumor growth, another 16 mice models with melanoma were established and 8 of them received IFN-γ injection (the experiment group). Results: When acute inflammation had influenc-es on tumor, a two-phase development was presented. In the early phase, the growth of tumor in the mice with wound was slower than that in the control group. In the early phase, the release of IFN-γ was higher and the release of TGF-β was lower in the experiment group. In the later phase, the growth of tumor in the mice with wound was similar to that in the controls and the release of TGF-β was higher. In vivo experiment con- firmed the above results. In the early phase, the release of TGF-β was not significantly different between the experiment group and the control group (P>0.05). In the later phase, the release of TGF-β in the experiment group was higher than that in the control group (P<0.05). Conclusion: In the early phase of acute inflamma-tion, inhibitory effects of IFN-y on tumor growth were presented. In the later phase, the inhibited tumor was re-sistant to IFN-γ through the release of TGF-β to balance the effect of inflammatory factors on tumor cells.

Objective To study the risk factors for the reflux of enteral nutrition in the mechanical ventilated ( MV) patients. Methods The data of reflux in 79 MV patients fed by enteral nutrition were collected. These patients were consecutively admitted to intensive care unit (ICU) of the Navy General Hospital from Jan. 2009 to Dec. 2010. Patients' performance conditions,patients' body position,location of feeding tube, way of feeding,tracheotomy,drug intervention were recorded. Simple logistic regression was used to analyze all the risk factors, and statistically significant variables were selected and adopted in multivariate and unconditioned Logistic regression analysis. Results The subjects averagely aged (58.6 ± 15. 3)years old,including 44 males and 35 females;with an APACHE Ⅱ score of 18. 1 ±4.0. Univariate analysis showed that age,position,location of feeding tube,way of feeding, tracheotomy et al were all assoctied with reflux. Advanced age( >60 y) ( OR = 4.577,95% CI 1. 459 - 14. 363, P =0. 009) was an independent risk factor for reflux; semisupination at 30° (OR =0.201,95%CI 0.057 -0.708,P = 0.013),nasalenteral tube (OR =0.267,95% CI0.072 -0.993,P = 0.049) ,and tracheotomy (OR = 0.232,95%CI0.070 -0.763,P =0.016) were independent protecting factors for the reflux. Conclusion Advanced age ( > 60 y) is a high risk factor for the MV patients with enteral nutrition;, semisupination at 30° .nasalenteral feeding,tracheotomy are low risk factors for the MV patients with enteral nutrition.

Objective To investigate the impact of PET-CT on the target volume delineation and precise radiothera?py planning for patients with advanced non-small cell lung cancer (NSCLC). Methods PET-CT scanning was performed in 30 histologically proved NSCLC patients. The gross tumor volume (GTV) was delineated, and radiotherapy planning was es?tablished with identical parameters based on the CT image and PET-CT fused image, respectively. The differences of doses between GTV, planning target volume (PTV) and organsat rise (OAR) were compared. Results PET-CT image results changed the target volume delineation in 30 patients with 8 increased and 22 decreased. There were no differences in GTV and PTV between the VGTV and VPTV statistically, although PET-CT image changed conventional CT image size sketch of GTV and PTV. The V20 of total lung decreased in the PlanPET-CT compared with that of PlanCT (P<0.05), but no differences were found in the V30 of total lung, mean lung dose (MLD), the data of spinal cord, esophagus and heart. Conclusion PET-CT may reduce the radiation injuries in the lung and improve the target dose.

ObjectiveTo investigate and compare the behavioral changes, neuron loss of hippocampus and mossy fiber sprouting between pilocarpine-induced status epilepticus (SE) model and pentylenetetrazole (PTZ) kindling model in rats.MethodsAfter two different epilepsy models were made, Vedio was adopted to observe the behavioral changes. Nissl staining and Neo-timms' staining were separately used to observe and compare the neuron loss of hippocampus and mossy fiber sprouting in the dentate gyrus (DG) at different time points during epileptogenisis.ResultsNo recurrent spontaneous seizure, no neuron loss and no mossy fiber sprouting were found in PTZ kindling model; whereas obvious neuron loss was found in CA1, CA3 of hippocampus and hilus of DG, and mossy fiber sprouting were found in pilocarpine model in parallel with recurrent spontaneous seizures. ConclusionPTZ kindling model resembles absence epilepsy in human, while pilocarpine-induced status epilepticus model resembles chronic temporal epilepsy in human. Neuron loss and mossy fiber sprouting may play an important role in epileptogenisis. Pilocarpine-induced epilepsy model can be regarded as an ideal chronic temporal epilepsy model.

Objective : To evaluate the effectiveness of interventions for human papillomavirus ( HPV ) vaccine hesitancy among female university students based on the precaution adoption process model (PAPM), so as to provide the evidence for improving the coverage of HPV vaccine in this population. Methods : HPV vaccine hesitant female students were selected using a cluster sampling method from Zhejiang Chinese Medical University, and randomly assigned to the PAPM group and control group. Students in the PAPM group received PAPM-based interventions for HPV vaccine hesitancy, while students in the control group were given routine interventions. The HPV-related knowledge, HPV vaccine-related knowledge and HPV vaccine hesitancy scores were collected from both groups prior to interventions ( T0 ), 0 ( T1 ), 1 ( T2 ) and 3 months post-interventions ( T3 ), and the effectiveness of interventions was evaluated using analysis of variance for repeated measures. Results : There were 147 students in the PAPM group and 141 students in the control group. In the PAPM group, 36.73% of the students majored in medical sciences, and 48.23% were freshmen; in the control group, 39.72% majored in medical sciences, and 50.35% were freshmen. The mean scores of HPV- and HPV vaccine-related knowledge were significantly greater in the PAPM group than in the control group, respectively ( T1, 5.29 vs. 4.91; T2, 4.27 vs. 4.22; T3, 4.22 vs. 4.04; P<0.05 ); however, no significant differences were detected in the HPV vaccine hesitancy scores between the two groups, respectively ( T1, 2.98 vs. 2.95; T2, 3.07 vs. 3.07; T3, 3.08 vs. 2.97; P>0.05 ). The mean scores of the confidence dimension ( T1, 3.37 vs. 3.23; T2, 3.48 vs. 3.40; T3, 3.38 vs. 3.25 ) and the dimension of influence by others ( T1, 3.44 vs. 3.33; T2, 3.42 vs. 3.37; T3, 3.46 vs. 3.27 ) were significantly greater in the PAPM group than in the control group (P<0.05), while the mean scores of the complacency dimension were significantly lower in the PAPM group than in the control group ( T1, 1.98 vs. 2.03; T2, 2.06 vs. 2.20; T3, 2.18 vs. 2.15; P<0.05 ). Conclusions PAPM-based interventions for HPV vaccine hesitancy may effectively improve the awareness of HPV and HPV vaccines, reduce complacency, and enhance the influence by others among female university students.
