AIM: To investigate the clinical effects of phacoemulsification and surgical techeniques in small pupil cataract after filtering operation of glaucoma.
METHODS: Thirty-six cases ( 36 eyes ) of small pupil cataract after filtering operation of glaucoma were underwent phacoemulsification combined with foldable intraocular lens implantation. Postoperative visual acuity, intraocular pressure filtration bleb and complications were observed. The follow-up time was 3mo.
RESULTS: The preoperative uncorrected visual acuity (UCVA) or best-corrected visual acuity ( BCVA) ≤0. 3 were in all patients. Postoperativerly, the UCVA or BCVA≥0. 3 after 1wk and 3mo were achieved in 23 eyes (63.89%) and 34 eyes (94. 44%). BCVA was <0. 3 in 2 eyes ( 5. 56%) including optic nerve atrophy of one eye and diabetic retinopathy of one eye. All patients were kept the level of normal intraocular pressure and completed filtering bleb, there were no serious complications.
CONCLUSION: Phacoemulsification in small pupil cataract after filtering operation of glaucoma was complex, and reasonable application of operation skills can still achieve better clinical results. The main factor of affecting the visual acuity is pre-existing retinal optic neuropathy.

OBJECTIVE:To evaluate the economics of alendronate sodium preventing osteoporotic fractures in postmenopausal women,and to provide reference for osteoporotic and osteopenia patients to select economical and effective therapy plan. METH-ODS:Using Markov economic model,TreeAge Pro 2011 software was used for cost-utility analysis using RCTs literature data of basic medication(calcium and vitamin D3)and basic medication combined with alendronate sodium as baseline data. Using quality adjusted life years(QALYs)and incremental cost utility ratio(ICUR)as economics evaluation indexes,the stability of established model was investigate by single factor sensitivity analysis. RESULTS:QALYs of the basic treatment group was 0.704 years,and QALYs of drug combination group was only 0.708 years. However,ICUR of two groups reached 714252.44. For the late period of hip fracture and other fractures,drug combination group was in high cost and low benefit,obviously had no economic advan-tage. For vertebral fractures,the cumulative probability of fracture in drug combination group was significantly lower than basic treatment group,and ICUR of the two groups was only 13902.17,with economic advantage. For hip fracture,the cumulative prob-ability of fracture in basic treatment group was the same as drug combination group,and ICUR was 19109.00,with economic ad-vantage. For wrist fractures,curative effect and economy needed further study. CONCLUSIONS:For the low-risk population with osteoporotic fractures,calcium and vitamin D3 are more economical in preventing osteoporosis fractures. For the high-risk popula-tion with vertebral and hip fractures,alendronate sodium combined with basic treatment is effective and economical.

Objective:To establish the cisplatin-resistant human lung adenocarcinoma cell line A549/(DDP) cisplatin and to study the relationship between EHD2 and drug resistance. Methods:DDP-resistant human lung cancer cell line A549/DDP was established by gradual and stepwise dose enhancement. MTT was used to measure drug sensitivity. Western blot and immunofluorescence were used to evaluate expression and subcellular localization of EHD2 and breast cancer resistance protein (BCRP). Results:The DDP-resistant cell line A549/DDP was established, with a resistance index of 7.6. EHD2 and BCRP expressions both increased and were enriched on the cell surface membrane. Conclusion:Both EHD2 and BCRP expressions were enriched on the resistant cell surface membrane, suggesting that EHD2 endocytic protein stabilizes BCRP and is involved in drug resistance.

Objective To compare the treatment effect of autologous blister skin grafting with ReCell autologous chromocyte grafting on cicatricial depigmentation caused by deep burn.Methods Thirty-four patients with cicatricial depigmentation caused by deep burn who were admitted into hospital from May 2012 to February 2015 were included in this study.The total 61 depigmentation areas were randomly divided into two groups;32 areas from 18 patients were treated with autologous blister skin grafting,and the other 29 areas from 16 patients were trea-ted with ReCell autologous chromocyte grafting.In the autologous blister skin grafting treated group,epidermis from the depigmentation area was removed by grinding with a BY-II AM type epidermal graft vitiligo treatment equipment.Then the autologous blister skin was harvested with the suction blistering method and grafted onto the wound of depigmentation area.In the ReCell autologous chromocyte grafting treated group,split-thickness skin flap was harvested by electric dermatome.Then the donor skin was processed into chromocyte suspension with the ReCell assay kit and evenly sprayed onto the depigmentation areas.The wound healing time and the pigment recovery 3 months after surgery were observed.Results The wound healing time of autologous blister skin grafting treated group was significantly shorter than that of ReCell autologous chromocyte grafting treated group (P <0.05 ).The effective rate of pigment recovery 3 months after surgery in autologous blister skin grafting treated group was markedly higher than that of ReCell autologous chromocyte grafting treated group(P <0.05 ). Conclusion The autologous epidermal grafting treatment using grinding and suction blistering method is simple and easy to perform,marked-ly effective,with no suture scar and low surgical risk,thus serving as a promising and ideal therapeutic method for burn scar depigmentation.

Coprinus comatus cultivated on cotton seed hull medium decomposed lignocellulose straggly and was high of absolute biological efficiency. Lignocellulose is the main carbon source for the fruiting stage of the fungus. There existed the positive correlation between the degradation rates of the cellulose and hemicellulose in the medium and the activities of extracellular CMCase (carboxymenthelcel lulase), FPase (filter paper cellulase) and HCase (hemicellu-lase), there also existed the positive correlation between the degradation rate of the lignin in the medium and the activity of extracellular laccase, but no correlation between the degradatio rate of the lignin in the medium and the activity of peroxidase. The activity of extracellular amylase was comparatively high at mycelial growth stage, and the protease activity peek was at teh time when the fruitbody matured.

Objective To explore the dynamic changes of expressions of surfactant protein A,B(SP-A,B)and aquaporin5(AQP5)mRNA of specificity mark in alveolar epithelial cell(AEC)of premature rats with chronic lung disease(CLD)and those significances.Methods Eighty premature rats were randomly and equally divided into model group(hyperoxia group)and control group(room air group).CLD was induced by hyperoxia exposure.The gene expressions of SP-A,SP-B and AQP5 were assayed with reverse transcription polymerase chain reaction(RT-PCR)after 1,3,7,14 and 21 days.Results Compared with control group,in hyperoxia group,the levels of SP-A and SP-B mRNA increased from day 7(Pa

Objective To explore the imageologic characteristics of pelvic fractures with artery injuries and the treatment methods for embolization of arteries.Methods From January 1999 to June 2005,60 cases(42 males and 18 females)aged 21-52 years(average 34.5 years)with pelvic fractures and unsteady blood dynamics were admitted into our hospital.There were 32 cases with traffic injury,13 with crushing injury,nine with fall injury and six with other injuries.The mean injury severity score was 39?16(16-66).All cases were hypetensive with systolic blood pressure less than 90 mm Hg on the arrival.Routine X-ray examination of dorsaventral,debouch and porch of pelvis was performed.The aver- age amount of blood transfusion was 2 886 ml.All cases underwent iliac artery angiography and pelvic ar- teriography.Results X-ray examination of pelvic fractures showed posterior pelvic fracture in 25 ca- ses,with 64 branches of blood vessels injured;anterior pelvic fracture in 13,with 17 branches of blood vessels injured;acetabular fracture in six,with 12 branches of blood vessels injured;and combined pel- vic fracture in 16,with 36 branches of blood vessels injured.Three cases died,with mortality rate of 5%.One case with common arterial thrombosis was treated with artificial blood vessel transplantation, four cases with external iliac artery injuries including one with artery rupture were treated with prosthesis, and among the three cases with external iliac artery thrombosis,one was treated with dislodgment of thrombosis,one treated with recanalization of thrombolysis and one did not give any treatment.Fifty cases with injury and bleeding of internal iliac artery and its branches were treated with arterial embolization. Five cases showed no obvious injury.Conclusions The types of artery injuries can be predicted through X-ray of pelvic fracture.Posterior pelvic fracture may easily cause injury to superior gluteal arter- ies,iliac lumber arteries,and lateral sacral arteries.While anterior pelvic fracture will cause injury to obturator arteries.Superior gluteal artery is susceptible to injury.Embolization of injured arteries and an- astomosis are preferred treatment for pelvic arterial disruptions.

Objective To evaluate the effectiveness of treating glioma in combination with drugs multiply by comparing the size of tumor and the survival time of different groups in rat glioma after targeted blood-brain barrier (BBB ) disruption by MRI-guided focused ultrasound.Methods The stereotaxis instruments and the 10 μl gas-tight syringes were used to inject gliosarcoma cells into the targeted area of the brain in 50 male Sprague-Dawley rats.The glioma-bearing rat model was established.Each rat received either:(1 )no treatment (control;n =8);(2)single liposomal doxorubicin (DOX;n = 10);(3)multiple DOX (n =10);(4)single Avastin (AVS)and DOX (n =10);(5)multiple AVS and DOX (n =10).The SonoVue microbubble ultrasonic contrast agent and DOX or AVS were injected into the tail vein respectively on day 12 after implantation.The tumor size was measured by MRI on pre-treatment,immediacy and once a week of post-treatment after targeted BBB disruption by focused ultrasound,and the life span in rat glioma was recorded.Results The mediam survival of different groups in rat glioma(The range of the life span 13-90 d):no treatment (7 d);single DOX (12 d);multiple DOX (1 5 d);single AVS + DOX (22 d), multiple AVS+ DOX (30 d).There was significant difference of the groups on mediam survival comparison (P < 0.01 ).The tumor growth pattern after post-treatment of different groups in rat glioma except control:single DOX was noticeable fast and multiple AVS+DOX was visibly delayed comparable to other groups,and finally the tumor size of multiple AVS + DOX even became small.Conclusions The microbubble blasting enhances the local tissue permeability and promotes the drug delivery of chemotherapy and anti-angiogenesis locally in glioma-bearing rats by MRI-guided focused ultrasound.Especially,the combination with drugs multiply has a synergism efficacy that may enhance the effectiveness of chemotherapy,reduce tumor growth,and even become small of the tumor size,and increase survival time significantly after BBB disruption.
