To study the effect of wearing overnight orthokeratology ( OK) contact lens on corneal topography and tears in adolescents.METHODS: The diopter, corneal curvature, corneal surface regularity index ( SRl ) , tear break - up time ( BUT ) , Schirmer l test, and corneal fluorescent ( FL ) were recordedon 40 (80 eyes) adolescent myopia patients (mean age 13. 68±2. 32 years), who had worn OK contact lensfor more than 1 year, with mean spherical equivalent refraction -3. 61 ± 1. 48D before wearing OK contact lens. These indexes were tested and recorded before the patients' wearing OK contact lens and 5 times (1wk and 1, 3, 6, 12mo after the first wearing) during the patients' overnight wearing OK contact lens for 8~10 hours per day.RESULTS: Compared with pre - wearing, at post -wearing OK contact lens 12mo, the mean spherical equivalent refraction was apparently decreased from -3.61±1. 48D to -1. 39±1. 31D(P<0. 01). The corneal curvature was significantly flattened from 42. 29 ± 1. 55D to 40.13±1. 41D (P<0. 01). Mean SRl was increased from 0. 34± 0. 01 to 0. 37 ± 0. 01 ( P<0. 01 ). Mean BUT was decreased from 10. 39±2. 25s to 7. 26±1. 77s (P<0. 01). These indexes were stable at 1wk after wearing OK contact lens overnight and had no significant differences during the following (1, 3, 6, 12mo after wearing) tests (P > 0. 05 ). There were no significant differences on Schirmer▏test during the 12mo of OK wearing(P>0. 05). The cases of corneal fluorescent staining increased were mainly grade l, and the number of corneal staining grade l at 1 wk and 1, 3, 6, 12 mo after wearing were 15 eyes (18. 8%), 9 eyes (11. 3%),13 eyes (16. 3%), 9 eyes (11. 3%), and 12 eyes (15. 0%). BUT of corneal staining grade l wasdecreased significantly, compared with the BUT of corneal staining grade 0 during the 12mo of OK wearing (P<0. 05). CONCLUSlON: OK contact lens can significantly decrease the degree of myopia and K value of corneal curvature without changing tear volume. However, tear film stability weakens, which needs regular follow-up.

Objective To observe the changes of hospitalization rates of patients with goiter in Lianyungang City in a coastal area with mild iodine deficiency in 2002-2010.Methods Medical reports of patients with goiter from county hospitals were studied at county level with a retrospective method.In accordance with the National Iodized Salt Monitoring Program,nine townships(towns) were taken from each county (district) [total of five counties(districts)]; four villages were selected from each township (town); salt samples were taken from eight households in each village,and salt iodine was determined using direct titration of sodium thiosulfate.Results The hospitalization rate of patient with goiter increased from 1.87/10 million in 2002 to 7.05/10 million in 2009,and then fluctuated to 6.06/10 million in 2010(x2 =281.91,P＜ 0.01).Among them,female's hospitalization rates were significantly higher than that of male 's(The variation range of x2 values were 35.23-116.04,all P ＜ 0.01),and the hospitalization rates of people over the age of 40 years were significantly higher than that of people less than 40 years of age(The variation range of x2 values were 33.04-263.04,all P ＜ 0.01),and the hospitalization rates of people in urban areas were significantly higher than that of people in rural areas (The variation range of x2 values were 18.35-140.00,all P ＜ 0.01).Average salt iodine was 27.61-30.13 mg/kg in 2002-2010.The coverage rate of iodized salt and the consumption rate of qualified iodized salt both increased year by year (x2 =183.75,211.99,P ＜ 0.01).There was a positive correlation between hospitalization rate of patient with goiter and coverage rate of iodized salt(spearman correlation coefficient was 0.83,P ＜ 0.05).There was a positive correlation between hospitalization rate of patient with goiter and the consumption rate of qualified iodized salt too (spearman correlation coefficient was 0.93,P ＜ 0.05).Conclusions In Lianyungang City,the hospitalization rate of patient with goiter,the coverage rate of iodized salt and the consumption rate of qualified iodized salt all show upward trend in 2002-2010.The relationship among them is worth further study.

OBJECTIVETo observe the clinical effects of needle-pricking therapy, a newly medical and minimally invasive technique, for functional retrograde ejaculation and to explore its mechanism. Methods Thirty-six patients with functional retrograde ejaculation were randomly divided into an observation group(19 cases) and a control group(17 cases) In the observation group,needle-pricking therapy was used at Guanyuan(CV 4) and bilateral sacral plexus nerve,lumbar 1 nerve and greater occipital nerve stimulating points,once a week. In the control group, midodrine tablets were prescribed orally,three times a day. All the treatment was given for 9 weeks. The clinical effects of the two groups were observed, and the levels of luteinizing hormone(LH), testosterone(Tes) and estra4 diol(E2) were compared between the two groups.

RESULTSThe total effective rate of the observation group was, 89. 47%(17/19), which was better than 47.06% (8/17) of the control group(P<0. 05). The LH and Tes were obviously increased and E2 was decreased compared with those before treatment in the observation group(all P< 0. 01). Tes was raised(P<0. 05) and E2 was apparently declined in the control group(P<0. 01). After treatment, the differences of serum LH and Tes were statistically significant between the two groups(both P<0. 01).

CONCLUSIONNeedle-pricking therapy has advantages for functional retrograde ejaculation probably in that stimulating lumbosacral nerves can strengthen the function of pelvic floor muscles and urethral expansion muscle and regulate sexual gland axis.

OBJECTIVETo observe the effect of ginkgolide nebulised inhalation in treating bronchial asthma.

METHODSAsthma patients of mild to moderate degree were randomly divided into three groups: the treated group treated by ginkgolide nebulised inhalation 10 mg/ml, twice daily, for 6 weeks in total, the positive control group, treated by cromlyn sodium nebulised inhalation 20 mg/10 ml, twice daily, for 6 weeks in total and the negative control group treated by normal saline 10 ml, twice daily, for 4 weeks in total. The changes on symptomatic scoring (Chetta' s method), pulmonary function (FEV1, PEF), serum eosinophil count, eosinophil cationic protein (ECP, determined by RIA), as well as airway response to ultrasonically nebulised distilled water (UNDW), and adverse reaction occurred in patients were observed. Results The symptomatic scorings in the treated and the positive control group were reduced from 5.1+/-2.3 and 6.0+/-2.6 to 1.6+/-1.7 and 1.6+/-1.7, respectively (both P<0.01) after 6 weeks of treatment. In the treated group, ECP was reduced from 6.7 microg/L to 4.3 microg/L (P<0.05), FEV1 and PEF were improved (P<0.05, P<0.01), while in positive control group, only improvement of FEV1 was found (P < 0.05). UNDW in the above two groups were reduced (P<0.01). Although decrease of symptomatic scoring was found in the negative control group, yet ECP, pulmonary function and airway response showed no improvement (P >0.05). Adverse reactions revealed were mainly chest stuffiness, stimulating cough, especially in the treated group, but were tolerable to most patients. Conclusion Ginkgolide has the action of fighting against asthmatic airway inflammation, which provides new means for treating bronchial asthma.

OBJECTIVETo explore therapeutic effects of modified femoral prosthesis applied in the initial posterior stabilized total knee arthroplasty.

METHODSFrom April 1, 2012 to January 1, 2013, 156 patients with knee osteoarthritis underwent posterior stabilized total knee arthroplasty by the same director of orthopedic surgeon. Sixty-one patients were treated with modified femoral prosthesis, including 7 males and 54 females, with an average age of (68.34 +/- 5.41) years old; and 95 patients were treated with conventional designed femoral prosthesis, including 14 males and 81 females, with an average age of (69.92 +/- 5.11) years old. Indexes including age, body mass index, Insall-Salvati index, type of prosthesis, occurrence rate of patella click syndrome, postoperative line of force of lower extremity and postoperative function of the knee joint were observed and recorded. And American Knee Society (AKS) score was used to evaluate the clinical results.

RESULTSAll the patients were followed up, and the duration ranged from 36 to 56 weeks, with a mean of 45.31 weeks. Among patients in the conventional designed femoral prosthesis group, 7 patients had patella click syndrome, but there was no patient having patellar click syndrome in the modified femoral prosthesis group. Postoperative knee activity of patients in the modified femoral prosthesis group was (110.98 +/- 10.32) degrees, which was better than (107.05 +/- 8.61) degrees in the conventional designed femoral prosthesis group. The AKS score in the modified femoral prosthesis group was 129.79 +/- 9.63 during 21 to 28 days after operation, which was higher than 126.85 +/- 7.79 in the conventional designed femoral prosthesis group.

CONCLUSIONNew designed femoral components are effective to reduce the occurrence rate of postoperative patellar click syndrome and obtain better early functional recovery from knee surgery.

Objective: To evaluate the short-term effect of thrombus aspiration catheters combining tiroifban medication for myocardial tissue reperfusion recovery in patients with acute ST-elevation myocardial infarction (STEMI).
Methods: A total of 105 STEMI patients with percutaneous coronary intervention (PCI) in our hospital from 2011-05 to 2013-05 were studied, there were 73 male and 32 female with the mean age of (58.39 ± 10.37) years. The patients were randomly divided into 2 groups, Group A, the patients received thrombus aspiration catheters with intravenous tiroifban, n=53 and Group B, the patients received tiroifban and PCI, n=52. The basic clinical features, myocardial tissue perfusion level, major adverse cardiovascular events (MACE) at post operative and in-hospital period were recorded, the cardiac function was examined by echocardiography at 6 months after PCI in both groups.
Results: The basic clinical features were similar between 2 groups. The thrombolysis in myocardial infarction trial (TIMI) 3 lfow rate was higher in Group A than that in Group B (92.45% vs 55.77%), P=0.000. TIMI 2 and TIMI 0~1 lfow rates were lower in Group A than that in Group B (7.55%vs 26.92%), P=0.008 and (0%vs 17.31%), P=0.002. The adjusted TIMI frame was lower in Group A (27.26±5.50) vs (38.98±5.42), P<0.001. The echocardiography at 6 months after PCI indicated that Group A had higher LVEF than that in Group B (0.55±0.06) vs (0.47±0.06), P<0.001;lower left ventricular end diastolic diameter (50.77±5.45) vs (54.76±5.34), P<0.001;less angina and target vessel revascularization (16.98%vs 40.38%), P=0.008 and (9.43%vs 17.31%), P=0.008. The incidence of MI, acute heart failure, cardiac death and non-target vessel revascularization were similar between 2 groups, P>0.05.
Conclusion:Thrombus aspiration catheters combining tiroifban medication may obviously improve the myocardial tissue reperfusion and the short-term cardiac function in STEMI patients after PCI, it could reduce the incidence of no-relfow without increasing MACE.

Objective: To explore the clinical response on cardiac resynchronization therapy (CRT) in patients of chronic heart failure (CHF) with different QRS wave morphology. Methods: A total of 52 CHF patients received CRT in our hospital and the Seventh People's Hospital of Zhengzhou City from 2010-03 to 2013-07 were retrospectively studied. The patients were divided into 3 groups: True-complete left bundle branch block (t-CLBBB) group,n=20, Classic LBBB (CLBBB) group,n=15 and IVCD group,n=17. The general clinical condition, the indexes of echocardiography at 6 months of follow-up study including left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), NYHA classiifcation and 6-MWT were examined and compared among different groups. Results: In general clinical condition, the ratio of non-ischemic heart disease patients in t-CLBBB group was higher than those in CLBBB group and IVCD group, allP<0.05. By 6 months follow-up study, LVEDD in t-CLBBB group (62.6 ± 8.9) mm was lower than those in CLBBB group (70.0 ± 8.9) mm and IVCD group (72.8 ± 8.0) mm, LVEF was higher in t-CLBBB group (38.5 ± 6.2) % than those in CLBBB group (31.7 ± 6.7) % and IVCD group (30.1 ± 6.7) %. NYHA classiifcation in t-CLBBB group (2.00 ± 0.45) grade was lower than those in CLBBB group (2.73 ± 0.80) grade and IVCD group (3.12 ± 0.78) grade . 6-MWT in t-CLBBB group (302.0 ± 57.9) m was longer than those in CLBBB group (257.3 ± 59.0) m and IVCD group (220.2 ± 57.9) m, allP<0.05. Conclusion: CRT is an effective method for treating CHD patients, different QRS morphology may have different response, the patients with t-CLBBB would make better response.
