Background Age-related cataract is the leading cause of visual impairment worldwide.To seek the effective prevention and drugs for management of cataract is important.Naphthalene-induced cataract of rat is an ideal animal model for the research of human age-related cataract,and aspirin has been proven to inhibit the development of human age-related cataract.ObjectiveThe present study is to investigate the role of aspirin on naphthalene-induced cataract.Methods Forty-five 150-160 g female SD rats were divided into three groups randomly.Naphthalene was orally taken with 0.5mg/kg per day for 3 days and then 1mg/kg per day for 70 days,and then 100mg/kg of aspirin was given per day for 70 days following four-day washout period in group A.In group B,the animals was given orally only naphthalene at the same way.No any intervention was used in group C.Naphthalene-induced cataract was examined under the slim lamp every week.The experimental animals were sacrificed and lenses were obtained in 70 days.α-Crystalline was extracted from lens homogenate and purified and identified using High Performance Liquid Chromatography(HPLC),2-dimentional electrophoresis gel and Western blot.Different abilities of α-crystalline to protect β low crystalline from aggregation were observed using ultraviolet spectrophotometer.Results Naphthalene-induced cataract formed at the third week in only naphthalene group but at the sixth week in naphthalene+aspirin group under the slim lamp.No significant difference was found in the degree of lenses opacity in the second week among these three groups(F=0.032,P=0.969).However,a statistically significant difference was seen in the degree of lenses opacity in the fourth,sixth,eighth and tenth week among these three groups(F= 5031.130,P=0.000;F=115964.000,P=0.000;F=169846.500,P=0.000;F= 195431.200,P=0.000).Themolecular chaperone-like activity was significantly higher than that of the naphthalene-induced group.Conclusion Aspirin delays the progression of lens opacification through protecting α-crystalline molecular chaperone-like activity.

Objective To study the effect of powder of Chinese Angelica and Peony (DSS) on hippocampus proteome of senescence accelerated mice (SAM). Methods Thirty female mice aged 12 months were used in our study, including 10 SAM-resistance/1 (SAMR1) and 20 SAM-prone/8 (SAMP8). The difference of hippocampus proteome among SAMP8, SAMR1, SAMP8 treated with DSS intragastrically at dose of 3.2 g/kg once a day for 30 d (SAMP8+DSS), was analyzed by two dimensional polyacryalmide gel electrophoresis (2DE). Results Compared with SAMR1, the expressions of 13 proteins in hippocampus of SAMP8 were up-regulated and that of 9 proteins were down-regulated significantly. Compared with SAMP8, the expressions of 21 proteins in hippocampus of SAMP8+DSS were up-regulated and that of 14 proteins were down-regulated significantly. Using MALDI-TOF-MS, the proteins with significant changes in expressions were identified by peptide fingerprinting map and the results were searched in MASCOT database, and sorted into 5 function groups including mitochondria-associated proteins, energy metabolism proteins, synaptic plasticity formation proteins, cytoskeletal proteins and others proteins. Conclusion The effects of DSS on hippocampus proteome of senescence accelerated mice were probably exerted via multi-target and multi-pathway mechanism.

Agitator is one of the essential factors to realize high efficient fermentation for high aerobic and viscous microorganisms, and the influence of different impeller combination on the fermentation process is very important. Welan gum is a microbial exopolysaccharide produced by Alcaligenes sp. under high aerobic and high viscos conditions. Computational fluid dynamics (CFD) numerical simulation was used for analyzing the distribution of velocity, shear rate and gas holdup in the welan fermentation reactor under six different impeller combinations. The best three combinations of impellers were applied to the fermentation of welan. By analyzing the fermentation performance, the MB-4-6 combination had better effect on dissolved oxygen and velocity. The content of welan was increased by 13%. Furthermore, the viscosity of production were also increased.

Background Pseudoexfoliation syndrome (PEX) is often complicated with cataract,accompanied by zonular defects.Zonular related complications easily happened intraoperatively and postoperatively.It is very important to choose the operating timing and method to reduce the complications and improve curative effects.However,relative study is rare.Objective This study was to analyze the curative effects of cataract extraction and intraocular lens (IOL) implantation for PEX combined cataract (PEXC) with zonular defect and discuss the appropriate operation timing and method.Methods A serial cases-observational study was performed,and written informed consent was obtained from each patient prior to ocular surgery.Twenty-three eyes of 21 patients with PEXC and zonular defect were included and received PEXC surgery in Second People's Hospital of Kashi from July 2012 to December 2015.The patients were divided into phacodonesis type (18 eyes) and subluxation of lens (5 eyes) based on the severity of zonular defect and grade Ⅱ (4 eyes),grade Ⅲ (9 eyes),grade Ⅳ (7 eyes) and grade Ⅴ (3 eyes) nuclei based on the hardness of lens nuclei.Phacoemulsification combined capsular tension ring (CTR) or modified CTR (MCTR) insertion and IOL implantation was carried out for grade Ⅱ and Ⅲ nuclei with phacodonesis eyes.or extracapsular cataract extraction combined CTR and IOL implantation was carried out for grade Ⅳ and Ⅴ nuclei with phacodonesis eyes,and phacoemulsification combined MCTR insertion and IOL implantation,or lens loop nucleusdeliver,anterior vitrectomy combined suspensory IOL implantation were performed for subluxation eyes.The patients were followed up for consecutive 3 months,and optimal operation timing,best corrected visual acuity (BCVA),intraocular pressure (IOP),complications and anterior capsular opening,IOL position were assessed.Results In the patients with phacodonesis,CTR was inserted in 10 eyes,and MCTR was inserted in 3 eyes,and extracapsular cataract extraction combined CTR and IOL implantation was carried out in 4 eyes and l eye received anterior vitrectomy combined suspensory IOL implantation.In the patient with subluxation of lens,only 1 eye finished successful phacoemulsification combined anterior vitrectomy and suspensory IOL implantation,and other 4 eyes received lens loop nucleus-deliver,anterior vitrectomy combined suspensory IOL implantation.The BCVA of the operated eyes was ＞0.5 in 4 eyes,＞0.3-≤0.5 in 6 eyes,＞0.1-≤0.3 in 8 eyes,≤0.1 in 5 eyes,which was better than that before surgery (X2 =17.29,P＜0.01).The IOP was (16.82 ±2.25) mmHg before surgery and reached (16.12±2.67) mmHg 3 months after surgery,with a significant difference between them (t=0.108,P＞0.05).The intra-and post-operative complications included small pupil,corneal edema,residual cortex and posterior capsular opacification.Conclusions The operative process of PEXC eyes with zonular defect is complex.The choice of operative time and methods depends upon the type of zonular defect,hardness of lens nuleus,with or without subluxation of lens.A carefully ocular examination before operation is crucial for the therapy of PEXC.

Objective To explore the clinical values of the modified thoracic drainage devices that were applied in treatment of primary spontaneous pneumothorax patients who underwent single-port video-assisted thoracoscopic surgery. Methods Clinical data of 82 primary spontaneous pneumothorax patients who underwent single-port video-assisted thoracoscopic lung wedge resection and pleurodesis from January 1st, 2015 to August 31st, 2016 was analyzed retrospectively. These patients, according to the thoracic drainage devices, were divided into traditional group (Group A, n = 42) or modified group (Group B, n = 40). These statistical data, including duration of thoracic drainage, lengths of hospital stay, duration of using antibiotic, amounts of pleural drainage, scales of pain, and complications of the two groups of patients in postoperative stage, were compared. Results There was no significant differences (P > 0.05) in volumes of thoracic drainage while there were significant differences (P < 0.05) in duration of thoracic drainage, lengths of hospital stay, duration of using antibiotic, scales of pain, and complications in postoperative stage between the two groups. And patients in group B had shorter time of thoracic drainage, hospital stay, and using antibiotic, lower scales of pain and rates of complications when compared with group A. Conclusion There are some clinical values of application of modified thoracic drainage devices in treatment of primary spontaneous pneumothorax underwent single-port video-assisted thoracoscopic surgery, because of it could give the patients fast recovery and made the operations simpler.

Objective To investigate the effectiveness and safety of anterior vitrectomy combined with capsular retractor and Cionni modified capsular tension ring (MCTR) in traumatic lens subluxation surgery with anterior vitreous prolapse.Methods This study comprised 16 patients (16 eyes) of traumatic lens subluxation with anterior vitreous prolapse,in which iridodialysis was in 3 eyes,express implantation in 1 eye and Ahmed glaucoma valve implantation in 1 eye.According to the severity of lens subluxation,the patients were divided into three levels,including 90°-120° (7 eyes),120°-180° (5 eyes) and 180°-270° (4 eyes).Considering the anterior vitreous prolapse,anterior vitrectomy or/and pars plan vitrectomy was conducted with assistance of triamcinolone acetonide.After continuous curvilinear capsulorhexis,two to four capsular retractors were placed in the capsulorhexis to support and center the capsule.MCTR was inserted with scleral suture fixation after phacoemulsification.At last,the foldable IOL was implanted to capsular bag.Postoperative visual acuity,intra-and post-operative complications,anterior capsular opening,IOL positions and intraocular pressure (IOP) were assessed during 3 months' follow up.Results All patients had successfully undergone phacoemulsification,MCTR insertion and IOL implantation.Seven eyes were inserted with 2-eyelet MCTR and nine eyes were inserted with 1-eyelet MCTR.The postoperative visual acuity was better than 0.5 in 9 eyes,between 0.3 and 0.5 in 4 eyes,between 0.1 and 0.3 in 2 eyes,and less than 0.1 in 1 eye.Compared with pre-operation,the difference in the visual acuity was statistically significant (x2 =17.503,P =0.000).The scheimpflug images obtained from the Pentacam,which demonstrated that the IOL was well centered,and no MCTR and IOL decentration occurred.The common intraand post-operative complications were residual cortex,aqueous misdirection syndrome,anterior capsular tears,anterior capsular phimosis and posterior capsular opacification.Conclusion The effective application of anterior vitrectomy is the key point to reduce surgical complications.Anterior vitrectomy combined with insertion of capsular retractor and MCTR is an ideal surgical option for patients of traumatic lens subluxation with anterior vitreous prolapse.
