AIM:To compare the difference between diopter of refration measured after cycloplegic mydriasis with retinoscopy and hand-held autorefractor so as to explore the feasibility of using hand - held autorefractor for refraction screening in cadet candidates.
METHODS:Respectively using hand-held autorefractor and streak retinoscope to do optometry examination in 317 cadet candidates students ( 634 eyes ) after mydriasis. Main index of refraction values ( spherical, cylindrical mirror degree and axial) were analyzed by difference test and correlation analysis. And the elimination rate was comparatively analyzed.
RESULTS: Diopters of sphere and cyclic refraction measured by hand-held autorefration were significantly higher than those by retinoscopy ( P< 0. 05 ), but the correction analysis showed that there was high correlation (r=0. 733, 0. 694), axial of refration measured by these two methods were non - significant ( P > 0. 05 ). The disqualifying rate using autorefraction was much higher than that using retinoscopy. It was easy to be wrongly eliminated.
CONCLUSION:Because of the high correlation between diopters of autorefraction measured by retinascopy and autorefractor, autorefraction has application value in refraction screening in cadet candidates with normal vision.

To the cataract patient after corneal refractive surgery, if the intraocular lens power was determined by conventional formulas, different refractive errors may be produced after intraocular lens implantation.This inaccuracy of the lens power mainly came from 2 aspects-errors of corneal refractive power measurement and errors of formulas.Besides, imprecise of ocular axial length measurement and invalid lens position calculation also contributed to the inaccuracy of lens power.Therefore, in order to reduce refractive errors of cataractous surgery in patient underwent refractive surgery, appropriate method should be used to estimate the refractive power of corneal, and proper formula should be selected to calculate intraocular lens power.

OBJECTIVETo compare the clinical outcomes of anterior cervical decompression plus sublevel fusion and posterior cervical laminoplasty in treating multilevel cervical spondylotic myelopathy.

METHODSThe clinical data of 56 patients with multilevel cervical spondylotic myelopathy were retrospectively analyzed from July 2009 to June 2012. There were 32 males and 24 females, aged from 42 to 79 years old with an average of (56.9 +/- 12.8) years. All patients had the typical clinical features of cervical spondylotic myelopathy,radiological evidences, and courses of disease were from 2 months to 16 years with an average of (10.6 +/- 3.2)years. Of them,34 patients were treated with anterior cervical decompression plus sublevel fusion (anterior fusion group) and 22 patients with posterior cervical laminoplasty (posterior laminoplasty group). JOA score and radiological data were used to evaluate the clinical results:

RESULTSNo complications about nerve and blood vessel was found and the patients were followed up from 24 to 36 months with an average of 28.6 months. In anterior fusion group, the cervical anterior column height was significantly increased and the anterior cervical curvature angle was significantly decreased at 2 weeks after surgery (P < 0.05). In posterior laminoplasty group, there was no significant difference in above items between preoperative and postoperative at 2 weeks,final follow-up. Postoperative at 2 weeks and final follow-up, there was significant difference in anterior cervical curvature angle between two groups (P<0.05). Postoperative JOA score had obviously improved in all patients, at 3 months after operation and final follow-up, anterior fusion group was better than that of posterior laminoplasty group (P < .05).

CONCLUSIONThe anterior sublevel fusion can effectively restore cervical anterior column height, and compared with the posterior cervical laminoplasty, it can obviously improve the spinal cord function. It is an effective method for the multilevel cervical spondylotic myelopathv.

OBJECTIVETo explore the effect of Peitu Shengjin Recipe (PSR) on nutritional states and immune functions of stable phase chronic obstructive pulmonary disease (COPD) patients.

METHODSTotally 62 stable phase COPD patients were randomly assigned to the treatment group (30 cases) and the control group (32 cases). All patients inhaled Seretide (50/500 µg), twice per day. Besides, patients in the treatment group additionally received PSR, one dose per day. After three months of treatment, the COPD assessment test (CAT) score, the index of nutritional states [including body mass index (BMI) , thickness of skin fold (TSF), mid-arm muscle circumference (MAMC), serum albumin, serum prealbumin], and immune functions (including IgA, IgM, and IgG) were compared between the two groups.

RESULTSBy the end of the treatment, the CAT score decreased more obviously in the treatment group than in the control group (P < 0.05). The improvement of BMI, TSF, MAMC, serum albumin, and serum prealbumin was better in the treatment group than in the control group (P < 0.05). IgM and IgG also increased more in the treatment group (P < 0.05). There was no statistical difference in IgA between the two groups (P > 0.05).

CONCLUSIONSAdditionally use of PSR could improve nutritional states and immune functions of stable phase COPD patients to some extent. Meanwhile, it also could improve their health related quality of life.

Objective:The objective of this research is to study the serum level of the high-mobility group protein B1 (HMGB1) in human ovarian tumor (OvCa) and in a healthy control. This study also aims to identify different HMGB1 levels before and after sur-gery and to explore the inhibitory effect of HMGB1 gene silencing in the proliferation and invasion ability of OvCa. Methods: En-zyme-linked immunosorbent assay was used to measure the serum level of HMGB1 in OvCa patients and healthy subjects. Lentivirus vector with HMGB1 shRNA was constructed and used to infect OvCa cells. The expressions of HMGB1 mRNA and protein were test-ed by real-time PCR and Western blot. Cell proliferation was detected using the Cell Counting Kit-8 assay, whereas cell invasion and migration were detected by Transwell assay. Results:The serum level of HMGB1 was more elevated in patients with malignant diseas-es compared with individuals with benign diseases and the control groups. In the malignant group, the serum level of HMGB1 de-creased noticeably after therapy. Down-regulation of HMGB1 expression resulted in the inhibition of the biological behavior and metas-tasis of ovarian cancer cells. Conclusion: HMGB1 is closely associated with clinicopathologic features of OvCa. Knockdown of HMGB1 expression can significantly inhibit cell proliferation, cell migration, and cell invasion of OvCa. These findings indicate that HMGB1 can function as a therapeutic target for ovarian neoplasm in the future.

Objective To evaluate the effect of olmesartan medoxomil tablets (olmesartan) in comparison with Olmetec on 24 h ambulatory blood pressure (ABPM) and blood pressure variability (BPV)in patients with mild to moderate hypertension.Methods A randomized,double-blind,double-mimic controlled trial was performed.Forty-eight patients with mild to moderate essential hypertension were randomly into treatment group (olmesartan) and control group (Olmetec) for eight weeks.The ABPM was taken before and at the end of the trial.Results After eight weeks,treatment with olmesartan induced a significant reduction in ABPM in patients [(9 ± 3)/(11 ± 3) mmHg (1 mmHg =0.133 kPa)],which is similar with the reduction by Olmetec [(9 ± 4) / (9 ± 5) mmHg],P ＞ 0.05.This situation holds for BPV with the standard deviations of 24 h,systolic blood pressure/diastolic blood pressure of pre-treatment and pro-treatment were (10 ± 2)/(11 ± 3) mmHg vs (10 ± 3)/(12 ± 2) mmHg in olmesartan group,and (10 ± 3)/(11 ±3) mmHg vs (12 ±3)/(12 ±4) mmHg in Olmetec group.(3) There is no difference in the rate of adverse event between olmesartan (10.42％) and Olmetec (8.33％) treatment(P ＞ 0.05).Conclusion Similar to Olmetec,treatment with olmesartan once daily can significantly reduce ABPM in patients with mild to moderate essential hypertension.

Objective: This research explores the relationship between the immuno-suppression function of regulatory T cells (Treg) in the ascites of ovarian cancer (OC) patients, the clinico-pathologic features of these patients, and the correlation of the function of Treg with initial treatment and relapse status of the patients to further investigate the specific mechanism of immuno-regulatory func-tion of CD4+ CD25+ Treg in the ascites of OC. Methods: Immuno-magnetic activated cell sorting (MACS) was conducted to sort CD4+CD25+Treg and autologous CD4+CD25-Treg from the ascites of 28 OC patients. Carboxyfluorescein-diacetate succinimidyl ester (CFSE) was used to label the autologous CD4+CD25-Treg. These labeled cells were then used as controls and co-cultured with autologous CD4+CD25+Treg at the ratio of 1∶1 or 1∶2. The mean inhibition ratio of Treg in specimens to the proliferation of autolo-gous CD4+ CD25-Treg was calculated after the flow cytometry of the CFSE expression and Modfit software analysis of the CD4+CD25-Treg proliferation index (PI) were performed. Anti-IL-10 and/or anti-TGF-β1 antibodies were neutralized to investigate whether the CD4+CD25+Treg-mediated immuno-suppression escaped through the ascites can produce a marked effect by the inhibitory cyto-kine IL-10 or TGF-β1. Results: The mean inhibition ratio of CD4+ CD25- Treg in the ascites of stage Ⅲ to Ⅳ OC patients was (75.72±17.04)%, which is significantly higher than that of stageⅠtoⅡOC patients (59.61±16.97)%;P<0.05. In addition, Treg in the as-cites of OC patients with recurrent disease showed a significantly higher inhibition ratio than that of patients with primary disease;P<0.001. Moreover, Treg in groups added into neutralizing anti-IL-10 and/or anti-TGF-β1 antibodies displayed significantly lower depres-sant effect than the control group;P<0.05. Conclusion:The immuno-suppression of CD4+CD25+Treg in the ascites of OC patients is correlated with the tumor staging and status of the primary or recurrent diseases. Moreover, Treg may indicate a suppressor function by secreting cytokine IL-10 and TGF-β1.
