Objective To investigate the expression and characteristics distribution of ciliary neurotrophic factor (CNTF) and its receptor during the development of retina of healthy Sprague-Dawley(SD)and Royal College of Surgeons (RCS) rats with hereditary retinal degeneration. Methods The expression and distribution of ciliary neurotrophic factor and its receptor were detected by immunohistochemical staining in the retinal paraffin sections of SD and RCS rats from newborn to 12 moths old. Results In the normal retina of SD rats 0-7 days after birth, positive CNTF staining was found in all of the retinal layers and the staining of ganglion cells strengthened and other cells weakened as the age of rats increased; the staining of ganglion cells reached the peak at the 4th week and lasted till the agedness. The same results of the CNTF staining were also found in RCS rats retina. Weak positive staining of CNTFR in all of the retinal layers was seen in the 0-3-day-old SD rats; the ganglion cells were darkly stained and incontinuous positive staining at the site which would develop to be the external segment was found; as the age increased, the positive staining of external segment of photoreceptor enhanced and reached the peak at the 14-28th day after birth. At the 56th day, the staining of ganglion cells in retina of SD rats was strengthened while the staining of external segment weakened till the agedness. The expression of CNTFR in retina of 3-14-day-old RCS rats was the same as which of normal SD rats basically, but the staining of external segment weakened obviously from the 21st day on, and negative staining of external and positive ganglion cells were detected at the 28th day till the agedness. Conclusions Expression of CNTF in normal SD rats and RCS rats with hereditary retinal degeneration is almost the same. The presence of significant difference of expression of CNTFR between normal SD rats retina and RCS rats retina may provide the experimental gist for the CNTF treatment to retinal degeneration.

Objective To identify the risk factors for the development of intraoperative hypothermia in the patients undergoing thoracic surgery.Methods One hundred twenty patients of both sexes,aged 23-83 yr,weighing 43-92 kg,of ASA physical status Ⅰ or Ⅱ,scheduled for elective thoracic surgery,who had an expected surgical duration of more than 2 h,with the core body temperature of 36.0-37.5 ℃,were included.After admission to the operating room,the core body temperature was measured.Intraoperative nasopharyngeal temperature of lower than 36 ℃ was defined as hypothermia.The patients were randomly divided into hypothermia group or non-hypothermia group according to whether or not intraoperative hypothermia occurred.Factors including the patient characteristics,the total amount of fluid infused (including the volume of blood transfused),duration and way of anesthesia and duration and type of surgery were recorded.The risk factors associated with intraoperative hypothermia were identified by logistic regression analysis.Results A total of 94 patients developed hypothermia during surgery,and the incidence of hypothermia was 78.3％.The lowest body temperature was 33.6 ℃.There was significant difference between the two groups in age,duration of surgery,the total amount of fluid infused,and the body temperature when patients were admitted to the operating room.Logistic regression analysis revealed that the total amount of fluid infused＞2 000 ml (OR =3.499) and low body temperature when patients were admitted to the operating room (OR =0.074) were independent risk factors for intraoperative hypothermia in the patients undergoing thoracic surgery.Conclusion The total amount of intravenous fluid infused＞2 000 ml and low body temperature when patients were admitted to the operating room are independent risk factors in the patients undergoing thoracic surgery.

Objective:To observe influence of preoperative sufentanil delayed preconditioning (SPC) on perioperative cogni‐tive function and myocardial protection effect in patients undergoing on -pump coronary artery bypass grafting (OP‐CABG) .Methods:A total of 60 patients undergoing selective OPCABG were randomly and equally divided into sufentanil group (SPC group) and routine treatment control group (control group) ,blood sample was collected before operation ,1h , 6h ,12h ,24h and 48h after aorta declamping to measure level of cardiac troponin I (cTnT );and all patients received neu‐ropsychological assessment before and 7d after operation .Results:Compared with control group ,there was significant re‐ductions in serum cTnI levels [1h:(23.66 ± 3.15) ng/ml vs .(14.96 ± 2.13) ng/ml] in sufentanil group from 1h after aor‐ta declamping to 48h after CABG ,P<0.05 all .The inotropic agent usage score on 12h ,24h and 48h after entering ICU of sufentanil group was significantly lower than that of control group [12h:(6.4 ± 0.6) scores vs .(8.4 ± 0.6) scores] , P<0.05 all .Incidence rate of postoperative cognitive dysfunction (POCD) in sufentanil group was significantly lower than that of control group (13.3% vs .30.0% ,P=0.041) .Conclusion:Preoperative sufentanil delayed preconditioning posses‐ses myocardial protection effect , and reduce incidence rate of cognitive dysfunction so also possesses certain brain protection in patients undergoing on-pump coronary artery bypass grafting .

Objective To systematically review the efficacy and safety of solifenacin in the treatment of patients with bladder spasm after transurethral resection of prostate based on current evidence.Methods We searched Pubmed,EMbase,the Cochrane Library,CBM,CNKI,VIP and Wanfang Database from the establishment to October 2016 for the published literature on the treatment of patients with bladder spasm after transurethral resection of prostate with solifenacin.Two reviewers independently screened literature,extracted data and assessed the risk of bias of included studies.Then,meta-analysis was performed using RevMan 5.3 software.Results A total of 11 RCTs involving 621 patients were included.The results of meta-analysis showed that:compared with the no-solifenacin group(n=311),the numbers of bladder spasm episodes[MD=-1.38,95%CI(-1.97,-0.97)P<0.00001],duration of bladder spasm[MD=-0.26,95%CI(-0.41,-0.11),P=0.0008],the time of bladder perfusion clearance[MD=-0.59,95%CI(-0.88,-0.29),P<0.0001],indwelling catheter delivery[MD=-0.29,95%CI(-0.48,-0.11),P=0.09]in solifenacin group(n=310) reduced significantly,and there was no statistical difference in the incidence of overall adverse events between the two groups[RR=0.71,95%CI(0.17,2.98),P=0.64].Conclusion Current evidence indicates that solifenacin is more effective and safe in the treatment of patients with bladder spasm after transurethral resection of prostate.Due to the limited quantity and quality of the include studies,more high quality studies are needed to verify the above conclusion.

To evaluate the neuroprotective effect of nerve growth factor ( NGF ) on acute angle-closure glaucoma patients after trabeculetomy.METHODS: Patients with viral keratitis who underwent trabeculectomy in treatment of acute angle - closure glaucoma in Xiamen Eye Center of Xiamen University from December 2011 to October 2013 were selected and completed the treatment, 61 eyes of 45 cases were followed up. The treatment group of 23 cases (32 eyes) with acute angle-closure glaucoma patients were treated by NGF gel for 3mo after trabeculetomy, while in the control group 22 cases (29 eyes) were treated by normal saline replaced NGF. All patients were followed up for at least 12mo, visual acuity, perimetry, retinal nerve fiber layer ( RNFL) thickness and cup/disc ratio of the patients were followed up during the treatment. The safety of topical use of NGF gel was also evaluated.RESULTS:ln all patients, the intraocular pressure ( lOP) was successfully controlled under 21mmHg and the visual acuity was markedly increased in the affected eye after trabeculectomy. Compared with control group, the postoperative lOP and visual acuity had no significant differences in treatment group (P>0. 05). The average light sensitivity of perimetry and mean defect were better than that in control group postoperative 6 and 12mo; The results of optical coherent tomography ( OCT ) and Heiderburg Retina Tomography ( HRT )-Ⅲ showed that RNFL thickness was significantly greater than that in control group, while cup/disc ratio significantly less than that in control group postoperative 6 and 12mo. Ocular surface damage, corneal endothelium to reduce and other eye complication were no observed in treatment group.CONCLUSlON:Acute angle-closure glaucoma treated by NGF gel after operation is effective and safe.

Objective To investigate the changes of thyroid hormone in peritoneal dialysis patients and analyse its impact factors, as well as the therapeutic effects of small dose of thyroxine.Methods 150 uremic patients in Hunan Provincial People’s Hospital from December 2013 to December 2014 were selected, 70 cases of uremia non-dialysis patients were divided into group A, while 80 uremia peritoneal dialysis for more than half a year were divided into group B.70 cases healthy examinees during the same period in our hospital were selected as control group ( group C ) . The total triiodothyronine (T3), total thyroxine (T4), free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH), hemoglobin (Hb), serum albumin (ALB), total cholesterol (TC), triglyceride (TG), serum creatinine (SCr), C reactive protein (CRP) and left ventricular ejection fraction ( LVEF) , subjective global assessment of nutritional act ( SGA) and other indicators were detected in three groups.Patients in group B were divided into two sub-groups according to thyroid hormone levels: B1 group had normal thyroid level while B2 abnormal.And the administration of small dose of thyroid hormone was given to patients in group B2, and the effect of the administration was evaluated by the above indexes.Results The FT3 in group A and B were significantly lower than that in group C (P<0.01).There were significant differences of levels of ALB, CRP, SGA between group B1 and group B2, and the FT3 level in group B was significant correlated with SGA, ALB, LVEF(r=0.815,P<0.001;r=0.780,P<0.001;r=0.953,P<0.001).After treated with small dose of thyroid hormone, FT3 and LVEF were improved while FT4, TSH, ALB, SGA, CRP were not improved in group B2.Conclusion The thyroid hormone level in patients with continuous ambulatory peritoneal dialysis decreases which is dominated with FT3.The decreased thyroid level is significantly correlated with nutrition ( ALB, SGA) and left ventricular function.The administration of small dose of thyroid hormone can improve the left ventricular systolic function.

Objective: To analyze the association of thrombocytosis with the prognosis of patients with gastric cancer.Methods: The clinical materials of 782 patients with gastric cancer who underwent initial surgery in our hospital between January 1995 and December 1999 were retrospectively analyzed.Kaplan- Meier and Log-Rank test were used to analyze the data.Prognostic factors were analyzed by multivariate Cox proportional hazards model.Results: Thrombocytosis oc-curred in 11.4% (87/782) patients.The platelet level was not significantly different among patients of different gender, tumor stage, and histological differentiation (P>0.05).However, a significant difference was observed in the platelet level among patients with different age and surgical approach (P<0.05).The 1-, 3-, and 5-year survival rates were 75.0%, 40.1% and 28.9% in patients without thrombocytosis and 52.8%, 16.9%, and 13.5% in patients with thrombocytosis (P=0.002).Univari-ate analysis showed that histological differentiation, pathological stage, surgical approach and thrombocytosis significantly affected the survival of patients.While age and gender had no significant impact on patient survival.Multivariate analysis showed that pathological stage, surgical approach, and thrombocytosis were independent prognostic factors for gastric can-cer.The relative risk of death of patients with thrombocytosis was elevated by 1.454 times (RR=1.454, 95% CI: 1.135～1.861, P=0.005).Conclusion: Thrombocytosis is an independent prognostic indicator for the survival of initially treated pa-tients with gastric cancer.

· AIM: To study the in situ relative intraocular position of the iris-claw phakic intraocular lens (PIOL)for high myopia using an anterior chamber optical coherence tomography (AC OCT)prototype.· METHODS: Six PIOLs (11.50 to 22.00D lens powers) were implanted in phakic myopic eyes. Using AC OCT, tomography was taken in the anterior chamber to measure the preoperative anterior chamber depth, postoperative distance between the PIOL and the corneal endothelium (endothelial-optic distance), and the postoperative distance between the PIOL and the crystalline lens.· RESULTS: Preoperative anterior chamber depth ranged from 3.27 to 3.91 mm and the postoperative endothelial-optic distance measured 2,07 to 2,24 mm. The distance between the crystalline lens and the posterior surface of the IOL ranged from 0.82 to 1.32 mm. Several tomography revealed the position of the PIOL on the iris, The pigment layer of the iris did not seem to be disturbed by the presence of the PIOL.· CONCLUSION, The original anterior chamber depths were reduced by 36,1% to 44.6% after implantation. This study of 6 eyes revealed that tomography taken by AC OCT are useful in verifying the intraocular position of the PIOL within the anterior chamber. Adequate space was maintained between the iris-fixated phakic intraocular lens and the corneal endothelium, angle, and crystalline lens.
