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.

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.

Background and purpose:Drug-resistance is the main obstacle in terms of efficacy of chemotherapy for leukemia, RNA interference(RNAi) strategy possesses the characteristics of specilization, high-efficiency and low-toxicity, and can effectively and specifically inhibit the overexpression of given gene. This study was designed to investigate the effect of small interfering RNA (siRNA) on expression of mdr1 gene and drug-resistance in multidrug-resistant human leukemia K562/ADM cell.Methods:Human multidrug-resistant leukemia cell line K562/ADM over-expressing mdr1 gene was used as the target cells, Two siRNAs (si-mdr1-1 and si-mdr1-2) targeted mdr1 gene were chemically synthesized and transfected into K562/ADM cells. Expression of mdr1 mRNA was determined by RT-PCR, P-glycoprotein (P-gp) expression was measured using flow cytometry (FCM), and the sensitivity of K562/ADM cells to adriamycin was assessed with a MTT colorimetric assay.Results:Two siRNAs (si-mdr1-1 and si-mdr1-2) specially designed in this study could markedly down-regulate the expression of mdr1 mRNA and its product P-gp in K562/ADM cells. After cells transfected with si-mdr1-1 or si-mdr1-2 for 24h and 48h, the inhibition of mdr1 mRNA expression in the cells for si-mdr1-1 was 55.5% and 22.5%; and for si-mdr1-2, 16.0% and 57.6%, respectively. Treated with siRNA for 72h, the expression intensity of P-gp in the two transfected cell lines decreased 74% and 85%, respectively. Both si-mdr1-1 and si-mdr1-2 significantly enhanced the sensitivity of K562/ADM cells to adriamycin and reversed their drug-resistance, the reversal efficiency was 2.52-folds and 1.96-folds, respectively.Conclusions:The siRNA could effectively and specifically silence the expression of mdr1 gene and overcome the drug-resistance mediated by P-gp in K562/ADM cells.

Objective To explore the feasibility of single port laparoscopy in classification and treatment of Meckel's diverticulum in children and its guiding treatment.Methods The clinical data in 75 children cases of Meckel's diverticulum with symptoms treated in our hospital from Aug.2011 to Aug.2015 were retrospectively analyzed.Meckel's diverticulum was classified under single port laparoscopy.The operation modes were selected according to different classifications.The excised materials were submitted to the pathologic examination.Results Among 75 children cases,50 cases were the simple type of Meckel's diverticulum and 25 cases were complex type of Meckel's diverticulum.The average operative time in the simple type and complex type was (38.93±8.75) min and(55.64 ± 13.27) min respectively,average bleeding amounts were (46.58 ± 15.81) mL and (50.12 [16.90) mL respectively,average postoperative hospitalization time was (7.33±1.41)d and (7.52 ± 1.68)d respectively,the operative time in the simple type was less than that in the complex type(P＜0.05),the other two indexes had no statistical difference between the two groups(P＞0.05).The ectopic gastric mucosal pathological change was only seen in the simple type,while the inflammatory manifestation in the complex type had higher proportion.The main clinical manifestations were lower gestational tract bleeding and infection.The two groups all obtained follow up.One case of simple type appeared the symptoms of abdominal pain and hematochezia and was cured after the second operation.Conclusion Meckel's diverticulum can be divided into the simple type and complex type under single port laparoscopy.The operation mode can be selected according to different types.This method is safe and reliable and is worthy of being clinically promoted.
