Background Refractive lens exchange is one of corrective surgeries for high myopic eyes and is concerned in clinic recently. Its clinical value is worthy of consideration. Objective This study was to investigate the efficacy and safety of refractive lens exchange for high myopic eyes. Methods Phacoemulsification and intraocular lens implantation was performed on 124 eyes of 65 patients with high myopia. The mean age of these patients was 51. 4±8. 57 years old,and the preoperative corrected visual acuity was 4. 11±0. 51. The mean spherical equivalent was ( -20. 17±5. 34) D. The mean axial length was (31. 33±2. 08) mm and intraocular lens power 2. 88 D. The follow-up time was 31 months. The uncorrective visual acuity, best corrective visual acuity, the spherical equivalent lens and complications were observed after operation. Written informed consent was obtained prior to the surgery. Results The uncorrective visual acuity improved after the operation in all the eyes. The uncorrective visual acuity was ≥0.5 in 15 eyes(12% ). The best corrected visual acuity improved in 114 eyes (92% ) following the surgery and that of 64 eyes (51. 6% ) was 2s 0. 5. The mean postoperative spherical equivalent was ( -2. 57 ± 1. 76 ) D in the entire follow-up duration. Posterior capsular opacification was found in 58 eyes (46. 7% ) and received laser capsulotomy. Retinal detachment occurred in 4 eyes throughout the follow-up period. Conclusion Refractive lens exchange is an effective and safe method for high myopic eyes. But preoperative fundus examination and long-term postoperative follow-up should be carried out to prevent the complications.

Objective To investigate the clinical characteristics and risk factors for healthcare-associated infection (HAI)in patients with severe chronic hepatitis B (CHB),and provide theoretical basis for preventing and controlling HAI.Methods Retrospective survey was used to investigate the occurrence of HAI in hospitalized patients with severe CHB in a hospital between January 2012 and January 2015,risk factors for HAI were analyzed. Results A total of 126 patients with severe CHB were investigated,49 patients developed 106 times of HAI, incidence of HAI was 38.89%.The main HAI site was respiratory tract (n=47,44.34%),the next was abdominal cavity (n=34,32.08%).A total of 76 isolates of pathogens were detected,gram-negative bacteria,gram-positive bacteria,and fungi accounted for 53.95%(n =41 ),43.42%(n =33),and 2.63%(n =2)respectively.Risk factors for HAI in patients with severe CHB were patients ’ age ≥ 60 years, length of hospital stay ≥ 30 days, complications,invasive operation,serum albumin < 35 g/L,and white blood cell count (WBC)< 4 × 109/L. Conclusion Incidence of HAI in patients with severe CHB is high,the majority are respiratory tract and abdominal cavity infection,risk factors are old age,long length of hospital stay,invasive operation,hypoalbuminemia,and low WBC count.

Objective To explore the risk factors of the recurrence of ischemic stroke and to supply theoretical basis for secondary prevention.Methods 612 patients with ischemic stroke were enrolled in the study and they were followed-up for 2 years to record the stroke recurrence.According to whether the recurrent stroke occurred,all the patients were divided into the recurrent group and the non-recurrent group.Logistic regression model was used to analyze the risk factors.Results Of 612 patients,90 patients suffered from recurrent stroke and the recurrence rate after 2 years was 14.7％.In the recurrent group,age,smoking,hypertension,diabetes,fibrillation atrial history and homocysteine level were significantly higher than those in non-recurrent group (P ＜ 0.05),compliance of anti-platelet drugs was significantly lower than that in non-recurrent group (P ＜ 0.01).Multivariate analysis suggested that age,smoking,hypertension,diabetes,atrial fibrillation history,homocysteine level and compliance of anti-platelet drugs were associated with recurrence of ischemic stroke (OR value =11.14,47.38,53.11,111.12,53.11,40.98,90.12,all P ＜ 0.05).Conclusion Age,smoking,hypertension,diabetes,atrial fibrillation history,homocysteine level and compliance of anti-platelet drugs are the independent risk factors of recurrent stroke.To enhance the interference of these risk factors are helpful for preventing the recurrence of stroke.

Patients with multiple myeloma (MM) have increased constantly in recent years, but treatment for patients with MM is currently unsatisfactory and it is necessary to develop new complementary therapies. Dendritic cells (DCs) are specialized antigen-presenting cells capable of initiating and regulating immune responses. Vaccination with tumor antigen-pulsed DCs has shown to be safe and possesses therapeutic effect against many tumors. In this review, the various types of MM-associated antigens and clinical trials on DC-based immunotherapy in MM are summarized, the development of DC immunotherapy for MM patients in future trials is discussed.

This study is to screen the Chinese herbal compounds which could inhibit the production of Abeta and investigate the underlying mechanism. Ten types of compounds which have potential value in the treatment of AD were selected as initial screening trial. The cell models which used could overexpress Abeta and beta-secretases or Abeta and gamma-secretases. Extracellular Abeta was determined by ELISA after the cell models treated with different concentrations of compounds (0.5-100 micromol x L(-1)), separately. Then the compounds were selected which could inhibit extracellular Abeta and their best concentration ranges were decided, too. Furthermore, the cell viability and apoptosis rate, the level of intracellular Abeta, beta and gamma-secretases were determined after the cell models treated with different concentrations of selected compounds. The results showed that 4 of the 10 compounds could reduce the level of extracellular Abeta; they were cryptotanshinone, astragalosides, gastrodin and paeoniflorin, and their best concentration ranges were 0.5-5.0, 0.5-5.0, 5.0-50, 1.0-25 micromol x L(-1), respectively. Further study indicated that the 4 selected compounds were nontoxic to the cellular models and lowering intracellular Abeta were more effective compared with extracellular; of which astragalosides and gastrodin showed dose-dependent inhibition to the activities of beta and gamma-secretases, with the maximum inhibiting rates of 78.2% and 80.3%, respectively. In conclusion, cryptotanshinone, astragalosides, gastrodin and paeoniflorin could inhibit the expression and secretion of Abeta, and the underlying inhibiting mechanism of astragalosides and gastrodin were related with the reduction of the beta and gamma-secretase activities, respectively.

Objective To investigate the correlation between dose volume histogram(DVH)of tumor targets and organs at risk(OAR)at CT-image based 192Ir brachytherapy and effects and complications for patients with locally advanced cervical cancer. Methods Ten patients with FIGO stage ⅢB cervical cancer received CT image-based 192Ir intracavitary brachytherapy after 54 Gy of three-dimentional four-field pelvic external beam radiotherapy and concurrent weekly cisplatin chemotherapy. Before each brachytherapy,CT images were acquired with applicators in place. Gross tumor volume(GTV), clinical target volume (CTV)and OAR were contoured and inverse treatment planning was designed and optimized by using PLATO treatment planning system. Conventional two-dimensional plans were also designed for comparison.The total intracavitary brachytherapy dose was 30 -42 Gy in 5 -7 fractions. The patients were followed, and the local control and complications were analyzed. The biologically equivalent dose(BED)and biologically equivalent dose in 2 Gy fractions(BED2)for GTV, CTV and OAR were calculated. The minimum dose in the most irradiated tissue volume 2 cm3(D2 cm3)adjacent to the applicator of the sigmoid colon, rectum,bladder and small bowel was determined from the DVH. Results The 1-year local pelvic control rate was 90% and grade 1-2 late complication of sigmoid colon and rectum was 50%. No grade 3 or more complications developed. On CT-image based planning, the BED and BED2 to 90% of the CTV(D90)were 95.50 Gy ± 7. 81 Gy and 79. 73 Gy ± 6. 57 Gy. The BED and BED2 to 90% of the GTV(D90)were 101.86 Gy ± 7.27 Gy and 84. 95 Gy ± 6. 1 Gy. The volume enclosed by 90% of prescribed dose(V90)for GTV and CTV were 92% ±4% and 87% ±7% respectively. The D2cm3 for rectum and sigmoid colon were 74. 97 Gy ±1.64 Gy and 67. 93 Gy ± 4. 30 Gy(EQD2, α/β = 3). Comparing with 2D brachytherapy plans , CT - image based planning has improved D90 and V90 for GTV and CTV with similar dose at point A and rectum reference point. Conclusions Computer tomography-image based 192Ir brachytherapy has resulted in the better dose distribution to the tumor targets with excellent tumor control and acceptable toxicity.
