AlM: To evaluate the effect of rigid gas permeable contact lens ( RGP ) in correcting high myopia and astigmatism.METHODS: Forty-one patients ( 65 eyes ) with myopia (-9. 03 ± 6. 19DS, maximum -23. 00DS) and astigmatism (-1. 41 ± 1. 32DC, maximum -5. 50DC) were fitted with RGP after strict routine ophthalmological examination, objective refraction and subjective refraction. All these patients were followed after 1wk, 1, 3mo and half one year.RESULTS:Sixty-five eyes were fitted with RGP (-9. 92± 5. 96DS). RGP base curve ( BC) was majorly located within the range 7. 20 ~8. 25mm. 46. 2% eyes with RGP achieved 1. 0 ( BCVA ) and 80. 1% achieved above 0. 6 ( BCVA) . However, with spectacles, the percent was 28%(1. 0) and 60% (>0. 6), respectively. BCVA of RGP was 0. 81 ± 0. 22, but BCVA with spectacles was 0. 66 ± 0. 28, there was statistical significance (P<0. 01). There were 40 eyes (62%) fitted with RGP whose vision were enhanced more than 1 line, 24 eyes ( 37%) whose vision were not changed and 1 eye (2%) whose vision were dropped 1 line.CONCLUSlON:RGP effectively improves visual acuity of high myopia and astigmatism compared with spectacles.

Objective To evaluate the feasibility,security and efficiency of general anaesthesia compared with regional anaesthesia for minimally-invasive thyroid surgery(MITS)with short-stay discharge.Methods 103 cases undergoing MITS with short-stay discharge from Jan.2013 to Jun.2013 in Fuzhou General Hospital were collected.54 patients were operated under regional anaesthesia and 49 under general anaesthesia.All variables of patients including demographic characteristics,vital signs (blood pressure,heart rate,blood glucose) during the operation,duration and type of operation,postoperative complications,difficulty in airway management and anesthesia consumption were recorded and analyzed.Results There was no difference in respect to level of blood glucose,length of hospital stay,discharge time,patient or operator satisfaction rate,anesthesia or operation complications rate between the two groups.Blood pressure (T1:(90 ± 7.0) vs (79 ± 8.3) mmHg,T2:(88 ± 6.8) vs (80 ±7.6) mmHg,P ＜0.05) and heart rate(T1:(130 ± 18.2) vs(101 ± 12.0)/min,T2:(120 ± 19.7) vs(103 ± 13.3)/min,P ＜ 0.05)level were higher,while the recovery time of anesthesia((0.3 ± 0.14)vs(0.8 ± 0.35)h,P ＜ 0.05)) and anesthesia consumption ((1350 ± 78) vs (2580 ± 220) yuan,P ＜ 0.05)) were lower in the regional anaesthesia group compared with those in the general anaesthesia group.Conclusions Both general anaesthesia and regional anaesthesia for MITS with short-stay discharge are safe and effective.General anesthesia has less psychological trauma,while regional anaesthesia has shorter recovery time and lower anesthetic consumption.

OBJECTIVETo analyze the data of angle variation on traction based on a finite element model of complete cervical spine with straight physiological curvature, and try to give experimental reference and suggestion in treating cervical spondylosis.

METHODSA 43-year-old female patient with straight cervical spine was chosen and the CT scan data were collected. By using specially designed modeling system, a high quality finite element model of complete cervical spine with straight physiological curvature is generated,which included ligament and muscle according to anatomy.

AIM: To purify and refold the inclusion body of a human anti-HBsAg scFv with a 6?His tag, and to determine the affinity constant of the purified recombinant product.METHODS: Solubilizing in buffers containing urea or guanidine hydrochloride (GuHCl), the inclusion body was purified by IMAC, and then refolded by dialysis against urea or GuHCl, at the same time, Ni 2+ charged chelate column was utilized for in situ refolding. The affinity constant of the refolded scFv, polished by immune-affinity chromatography, was determined by non-competitive ELISA. RESULTS: The refolded scFv with highest specific bioactivity was produced by dialysis against GuHCl. Under this condition, the recovery of target protein reached (61.08?1 45)%. The affinity constant of the polished scFv was confirmed to be(2.30?0.32) ?10 7 L/mol. CONCLUSION: The inclusion body studied in this paper can be refolded efficiently under optimal dialysis condition in vitro . The antigen-binding property of this recombinant scFv is not affected by the purification tag fused to the N terminal of the protein.

Objective To investigate the correlation factors for hot flashes in climacteric women so as to improve their quality of life. Methods A questionnaire was distributed among 792 climacteric women. The questionnaire items included general information, characteristics of menstruation, reproduction history, information of hot flashes, lifestyle and sexual life. Weight, height, blood pressure, waist and hip circumferences were measured. Logistic regression analysis was made to find out the correlation factors for hot flashes. Results Univariate logistic regression analysis showed that age, education, income, present characteristics of menstruation, dietary habit, soy products intake, physical exercise, satisfaction of sexual life, body mass index (BMI) and systolic blood pressure were significantly associated with hot flashes. Multivariate logistic regression analysis revealed that irregular menstruation or menopause, frequent exercise and higher systolic blood pressure were risk factors for hot flashes in climacteric women. However, higher education, soy products intake and satisfaction of sexual life were protection factors. Conclusion Guiding climacteric women to take moderate physical exercise, knowing more about climacterium, consuming more soy products and controlling diastolic blood pressure are likely to decrease the incidence of hot flashes.

Objective To investigate the effect of berberine pretreatment on hypoxia/reoxygenation (H/R)-induced apoptosis in human renal tubular epithelial cells.Methods The human renal tubular epithelial cells were cultured and seeded in culture dishes (2 ml/dish) or 96-well plates (200 μl/well) with the density of 1 ×106/ml.The cells were then randomly divided into 4 groups (n =30 each):normal control group (group C),berberine group (group B),H/R group and H/R + berberine group (H/R + B group).In groups B and H/R + B,berberine 10 μmol/L was added to the culture medium and the cells were incubated for 2 h.Groups H/R and H/R + B were then exposed to 94％ N2-5％ CO2-1％ O2 for 24 h followed by 3 h reoxygenation.The cell viability,apoptotic rate and level of malondialdehyde (MDA) and superoxide dismutase (SOD) were detected.The expression of caspase-3,activated caspase-3,cytochrome c,glucose-regulated protein 78 (GRP78) and C/EBP homologous protein (CHOP) was determined.The ratio of Bax/Bcl-2 was calculated.Results Compared with group C,the cell viability,SOD activity and caspase-3 expression were significantly decreased,the apoptotic rate,Bax/Bcl-2 ratio and concentration of MDA were increased,and the expression of activated caspase-3,cytochrome c,GRP78 and CHOP was up-regulated in groups H/R and H/R + B (P ＜ 0.05).Compared with group H/R,the cell viability,SOD activity and caspase-3 expression were significantly increased,the apoptotic rate,Bax/Bcl-2 ratio and concentration of MDA were decreased,and the expression of activated caspase-3,cytochrome c,GRP78 and CHOP was down-regulated in group H/R + B (P ＜ 0.05).Conclusion Berberine pretreatment can inhibit H/R-induced apoptosis in human renal tubular epithelial cells,and inhibition of mitochondrial stress pathway and endoplasmic reticulum stress pathway is involved in the mechanism.

Objective To study the potential role of tumor necrosis factor-α (TNF-α) induction in the development of mucosal barrier dysfunction in rats caused by acute intestinal ischemia-reperfusion injury, and to examine whether pretreatment with monoclonal antibody against TNF-α (TNF-α MoAb) would affect the release of D(-)-lactate after local gut ischemia followed by reperfusion. Methods Anesthetized Sprague-Dawley rats underwent superior mesenteric artery occlusion for 75 min followed by reperfusion for 6 hr. The rats were treated intravenously with either TNF-α MoAb (20 mg/kg) or albumin (20 mg/kg) 30 min prior to the onset of ischemia. Plasma D(-)-lactate levels were measured in both the portal and systemic blood by an enzymatic spectrophotometric assay. Intestinal TNF-αmRNA expression as well as protein levels were also measured at various intervals. In addition, a postmortem examination was performed together with a macropathological evaluation based on a four-grade scoring system.Results Intestinal ischemia resulted in a significant elevation in D(-)-lactate levels in the portal vein blood in both the control and treatment groups ( P ＜0.05). However, animals pretreated with TNF-α MoAb at 6 hr after reperfusion showed significant attenuation of an increase in both portal and systemic D(-)-lactate levels when compared with those only receiving albumin (P ＜ 0.05). In the control animals, a remarkable rise in intestinal TNF-α level was measured at 0.5 hr after clamp release ( P ＜ 0.01); however, prophylactic treatment with TNF-α MoAb completely annulled the increase of local TNF-α levels seen in the control animals. Similarly, after anti-TNF-α MoAb administration, intestinal TNF-α mRNA expression was markedly inhibited, which showed significant differences when compared with the control group at 0.5 hr, 2 hr and 6 hr after the release of occlusion ( P ＜ 0.05-0.01 ). In addition, the pathological examination showed marked intestinal lesions that formed during ischemia, which were much worse upon reperfusion,particularly at the 6 hr time point. These acute injuries were obviously attenuated in animals receiving TNF-α MoAb.Conclusions It appeared that acute intestinal ischemia was associated with failure of the mucosal barrier, resulting in increased plasma D(-)-lactate levels in both portal and systemic blood. These results suggest that TNF-α appears to be involved in the development of local damage associated with intestinal ischemic injury. Moreover, prophylactic treatment with TNF-α MoAb exerts preventive effects on ischemia/ reperfusion-induced circulating D (-)-lactate elevation and gut injury.
