AlM: To investigate the risk factors of diabetic retinopathy ( DR) in type 2 diabetes patients.METHODS:A total of 380 cases of type 2 diabetes were selected from January 2014 to June 2014, divided into DR group (126 cases) and non-diabetic retinopathy ( NDR) as control group (254 cases), all patients were underwent medical history, physical examinations, laboratory and assistance examinations. The prevalence and single factor and multiple factors of DR were analysed by the logistic regression model.RESULTS: The univariate logistic regression analysis showed that DR was associated with diabetes duration, systolic blood pressure, triglyceride, total cholesterol, low - density lipoprotein, urine protein, intraocular pressure, carotid intima - media thickness, peripheral neuropathy disease was the related risk factors for DR. ln multiple logistic regression analysis, only duration was the related risk factors for DR.CONCLUSlON:The occurrence of DR is the outcome of combined action of multiple factors, duration is an independent risk factor for occurrence of DR.

Objective The present study was aimed at investigating the effects of cholera toxin(CTx) on promoting the regeneration of retinal ganglion cells(RGCs) in hamster retina. Methods After optic nerve (ON) transection, an autologus sciatic nerve (attached graft, AG) was removed and sutured to the proximal stump of the ON. CT X was injected or (and) a small segment of sciatic nerve (SN) inserted intravitrously. Animals were separated into 5 groups:regenerating control group(AG groups and solution groups); AG+CT X groups; AG+SN groups; AG+CT X+SN groups; Effect and Dosage groups; Animals in the former 4 groups were allowed to survive for 2-6 weeks respectively. The regenerated RGCs were labeled retrogradely by granular blue, and the changes in number of regenerating RGCs in each retina were observed under fluorescent microscope. Results The mean numbers of regenerating RGCs in AG+CT X groups were increased and significantly higher than those in AG groups and solution groups at each time point( P

【Objective】 To examine the regeneration of NPY-immuno reactivity (IR) retinal ganglion cells (RGCs) and the effects of cholera toxin ( CTx) injected or/and peripheral nerve implanted on regeneration of NPY-IR RGCs. 【Methods】 16 adult golden hamsters were ramdomly divided into 4 groups. Optic nerve (ON) was transacted and a segment of autologous sciatic nerve (attached g raft, AG) was removed and sutured to the proximal stump of ON in regenerating co ntrol group (AG group). The animals in experimental groups were further treated with CTx injection or/and implantation of a short of segment sciatic nerve (SN) intravitrously. By using the retrograde labeling with fluorogold (FG) combined w ith fluorescent immunocytochemistry, the regenerated NPY-IR RGCs were observed and counted under fluorescent microscope. 【Results】 At 4 weeks after surgery, the mean number of regenerated NPY-IR RGCs per retina in AG group was 58±22 wh ich constitutes (3.36±0.65)% of the total regenerated RGCs. In AG+CTx, AG+SN and AG+CTx+SN experimental groups, the mean numbers of regenerated NPY-IR RGCs per retina were 143±47, 125±37 and 437±77 ordinally which constitute (5.15± 0.89)%, (5.34±0.37)% and (8.11±0.85)% of the total regenerated RGCs respec tively, which were increased significantly compared with those in AG group. 【Co nclusion】 The results show that the axotomized NPY-IR RGCs have th e capability of regenerating their axons into the attached PN graft, CTx and/or SN could enhance the regeneration of the NPY-IR RGCs.

AIM: To explore the main risk factors related to the incidence of endophthalmitis in patients after cataract surgery in China and to provide evidence for prevention.METHODS: The results of 5 studies on the main risk factors of endophthalmitis in patients after cataract surgery were analyzed by Meta-analysis method.
RESULTS: The pooled odds ratio values and 95% CI of age(≥70), diabetes, vitreous overflow, operative time ( ≥ 10min ), common operating room and control of using time of topical anesthetic were 1. 81(95% CI: 1. 43-1. 69),3. 66 (95% CI: 1. 64 - 8. 16),2. 21 (95% CI: 1. 46 -3. 32),3. 54 (95% CI: 2. 47 - 5. 06),2. 77 (95% CI: 2. 07 -3. 72),2. 09(95% CI: 1. 53-2. 86).
CONCLUSION: The main risk factors of endophthalmitis were the age(≥70), diabetes, vitreous overflow, operative time(≥10min), common operating room and control of using time of topical anesthetic.

Objective　To introduce the development of therapy of hilar cholangiocarcinoma. Methods　This summarization paper was made on the literatures review. Results　Extended radical resection, neoadjuvant chemotherapy, orthotopic liver transplantation, photodynamic therapy and molecular chemoradiotherapy might improve the survival rate. Conclusions　Surgical resection combined with other theraputic methods is the main treatment for hilar cholangiocarcinoma.

Objective To exploie the choices and timing of different treatment regimens of prostate cancer.Methods The complete clinical data of one case of localized high-risk prostate cancer was reported.The patient,aged 69 years old,was admitted to hospital with urinary frequency and dysuria for 2 years.Serum total PSA was 36.8ng/ml and prostate biopsy dignosed as prostate cancer.The Gleason score was 4 + 3,and the clinical stage was T2b N0M0.Results The patient underwent radical prostatectomy,salvage radiotherapy + androgen deprivation therapy,abiraterone,enzalutamide,Radium-223,docetaxel + prednisone chemotherapy and mitoxantrone + prednisone chemotherapy,which included almost all of the current domestic treatment regimens.The patient lived for 57 months from the initiation of treatment.Conclusions For the patients with high-risk prostate cancer,especially for elderly patients,they should firstly be recommended the treatment of radical radiotherapy + 2-3 years of androgen deprivation therapy.For young patients,radical prostatectomy + extended pelvic lymph node dissection as part of multi-modal therapies is considered to be a positive choice.However,for the patients with risk factors or recurrence after radical prostatectomy,the postoperative radiotherapy should be performed in order to reduce biochemical recurrence and improve local control.Currently,the order of choice of abiraterone,enzalutamide or docetaxel + prednisone chemotherapy,is based on the patient's situation,past history of treatment,symptoms,side effects as well as other related clinical features.

Objective To explore the effect of different doses of anthracycline on preoperative chemotherapy of breast cancer.Methods In 40 cases of breast cancer patients using small doses of anthracycline therapy, and classified as the control group, the other 40 patients using high-dose anthracycline therapy, and classified as observation group.Then observe two groups of patients were compared;the patients were in our hospital from January to December 2016 were treated.Results The total effective rate was 82.5% in the observation group and 62.5% in the control group, the difference between the two groups was statistically significant (P<0.05).The incidence of adverse reactions in the observation group was 0, the control group was 27.5%, and the incidence of adverse reactions in the two groups was statistically significant (P<0.05).Conclusion Different doses of anthracyclines on the clinical effect of chemotherapy before surgery for breast cancer research found that different the clinical effect of different doses produced by E100C and E75C, E100C can improve the treatment effect of the patients, and reduce the occurrence of toxicity, so it is worthy of reference.
