AIM:To observe the efficacy, complications and ocular surface tear dynamics of the treatment for pterygium combined with conjunctivochalasis by inferior limbal-stem-cell transplantation.
METHODS: All 30 patients ( 46 eyes ) diagnosed as pterygium combined with conjunctivochalasis in our hospital from December, 2010 to December, 2012 with a mean age of 61. 2y (SD 7. 2, range 49-75) were subjected to observation. After excision of nasal pterygium, an equivalent size of conjunctival flap linked with corneal limbal stem cell from inferior limbus was transplanted to the exposed sclera. Afterwards, the inferior bulbar conjunctiva was trimmed and fixed onto surface of sclera and inferior corneal limbus. After one-year follow-up, the comparisons regarding vision acuity between pre-operation and post-operation ( 1mo later ) as well as ocular-surface tear dynamics changes including several indexes like altitude and integrity of tear meniscus, break-up time ( BUT ) , corneal fluorescein staining and chloramphenicol gestation test before and 3mo after surgery were made. The operative complications and the recurrence rates 1y after operations were recorded.
RESULTS: Median visual acuity was 0. 2 (0. 04-0. 6) before the operation and median visual acuity was 0. 4 (0-04-1. 0) 1mo after the operation. Of total 46 eyes in 21 eyes ( 45. 7%), visual acuity improved. No vision changes were found in other 25 eyes ( 54. 3%). Significant difference ( P<0. 01 ) of vision acuity before and after surgery was found. In addition, break-up time ( BUT) , corneal fluorescein staining and chloramphenicol gestation test and altitude and integrity of tear meniscus show better results 3mo after surgery than that of pre-operation, which showed statistically significant ( P <0-05). After 1y follow-up, 33 eyes (71. 7%) healed while problems in 11 eyes ( 23%) were relieved. The total efficacy rate was 95. 6%. Nonetheless, invalid surgeries were noticed in two eyes ( 4. 4%) that affected by recurrence of pterygium. The 33 eyes (71. 7%) affected by conjunctivochalasis was cured in terms of subjective evaluation and improved in 9 eyes (19. 6 %), but 4 eyes (8. 7%) exhibited no evident improvement in terms of subjective complains. Total efficacy was 91. 3%. The 41 eyes (89. 1%) were reported to be normal while 5 eyes ( 10. 9%) were revealed to be abnormal in terms of objective therapeutic evaluation. And this condition was so-call conjunctivochalasis recurrence with a recurrence rate of 10. 9%. No proliferation of granulation, narrowing inferior fornix and malfunction of eye movements was found.
CONCLUSION: Inferior - limbal - stem - cell transplantation to treat pterygium combined with conjunctivochalasis obtains better results. It proves to eradicate or relieve symptoms of patients effectively and ameliorate ocular-surface tear dynamics.

Objective To investigate the expression of c-erbB-2 in breast cancer and its relationship with prognosis.Methods The expression of c-erbB-2 in breast cancer was detected by immunohistochemistry assays in 60 cases of breast cancer.Results The positive expression level of c-erbB-2 in invasive breast cancer was signifi-cantly higher than that in other kinds of breast cancer(P<0.01).The positive expression level of c-erbB-2 in the metastatic breast cancer with four lymph nodes was higher than in the early cancer with no lymph node involvement (P<0.01).The 10 years survival rate in negative expression of c-erbB-2 was higher than in positive expression(P<0.05).Conclusion c-erbB-2 is important for physicians to instruct the treatment of the breast cancer and judge the prognosis.

Objective To establish cell suspension culture system of Gentiana macrophylla.Methods Good cell line was selected by the methods of small cell aggregate and the effects of different media,inoculation age of cells,initial pH value,culture temperature,and rotation speed on cell growth and gentiopicroside accumulation were investigated.Results The eligible cell suspension culture conditions were:MS media as the basic medium,cells with inoculation age of 15 d,initial pH 7,and rotation speed of 110 r/min at 25 ℃,culturing in Erlenmeyer flasks.Conclusion Optimal cell suspension culture system of G.macrophylla has been established by shake flasks.The different effects of media on cell growth and gentiopicroside accumulation indicate that some inorganic ions have significant effects on regulation.

Objective To investigate the effects of carbohydrate and its concentration,nitrogen source,and metal ions on suspension cell growth of Gentiana macrophylla and gentiopicroside accumulation. Methods The cell dry weight and gentiopicroside content were measured under factors of different carbohydrate,NH4+/NO3-,Ca2+,and Zn2+ at various concentration. Results The optimum culture conditions are as follows:3% sucrose,NH4+/NO3-of 20/40,3 mmol/L Ca2+,0.007 49 mmol/L Zn2+. Conclusion Different carbohydrates and their concentration have significant effects on cell growth and gentiopicroside accumulation while high concentration of carbohydrates does not have such effect. NO3-is better than NH4+ for the cell growth. Ca2+ Remarkably influences both cell growth and gentiopicroside accumulation while Zn2+ contributes only to gentiopicroside content.

AIM: To study the protective effect of hepatic stimulator substance(HSS) on chemotherapeutic liver damage induced by cyclophosphamide and its possible mechanism.METHODS: The serum biochemical parameters,oxidative parameters and anti-oxidative parameters of liver tissue of male Kunming mice inoculated with S_(180) cells were measured.The pathology of the liver was observed with microscope.The weight of S_(180) sarcom was weighted.RESULTS: The elevation of MDA content of liver tissue and the less of GSH content and CAT,GSH-PX,GST,and SOD activities induced by CP were restored remarkably by HSS.The ALT and LDH activities of serum in HSS group which was compared with control group and CP group were not statistically distinctive.In the pathologic examination,spotty and focal necroses of hepatocytes in the liver of CP group were found with a great deal of inflammatory cells infiltration in the necrotic and portal areas,while the damage in the liver of HSS group was ameliorated obviously;The weight of S_(180) sarcom in CP group and HSS group was not statistically distinctive.CONCLUSION: The effect of HSS on CP-induced chemotherapeutic liver damage maybe due to anti-oxidative activity.

Objective To evaluate ischemia preconditioning (IP) and intermittent ischemia (II) in ameliorating the incidence of paraplegia. MethodCross clamping of the infrarenal aorta in New-Zealand rabbit was used to establish a spinal cord ischemia model. 25 rabbits were randomly divided into 3 groups. The continuous ischemia(CS) group (n=10) with the aorta clamped for 40 minutes. While in the IP group (n=6) the aorta was clamped for 3 sessions each lasting for 5 min, with 5 min interval between the sessions before 40 minutes clamping, in the Ⅱ group (n=9) the 40 min clamping was interposed by a 15 min interval. The muscle force of the lower extremity, the excitatory amino acid (EAA) in CSF, the malondiadehyde (MDA)in spinal cord and the pathology were compared between the groups.Result The muscle force of the lower extremity was better in Ⅱ and IP group than that in CS group (3.4?1.0) in Ⅱ, (3.5?0.8) in IP vs (1.3?1.4) in CS, all P

Objective To screen the high-efficiency predominant bacteria which can decompound 2-mercaptobenzothiazole, the accelerant for producing latex, in the organic wastewater. Methods Sampling from manufacturing environment, we got the predominant bacteria by primary screening, isolating and functional tests, and performed simulated test ground decompounding tests by using all bacteria. The enrichment of the predominant bacteria was followed by screen and identification to select the high-efficiency bacteria. Results 75 strains of predominant bacteria were obtained by primary screening. The simulated decompounding tests were performed after the mixed bacteria were tamed. The ratio of elimination for chemical oxygen demand (COD) was about 60.8%-97.7%, and the average was 77.2%. The predominant bacteria adhered to the surface of the active carbon, the carrier, and formed the biological film. Through screening and identification the Bacillus cereus showed to be predominant (90%). Conclusion The technology of high-efficiency predominant bacteria can be used for decompounding 2-mercaptobenzothiazole in the organic wastewater.
