AlM: To compare the effects of external approach microsurgery and conventional external approach surgery for retinal detachment ( RD) .METHODS: From January 2010 to January 2013, 60 patients (60 eyes) in our hospital were randomly divided into experimental group (29 cases, 29 eyes) and control group ( 31 cases, 31 eyes ) , the external approach microsurgery and conventional external approach surgery were performed respectively ( by the same skilled doctor ) . Retinal reattachment rate, visual acuity improvement rate and operative time were compared between two groups.RESULTS:lt cost shorter time for the external approach microsurgery than that of conventional external approach surgery ( P = 0. 0087 ). The once successful retinal reattachment rate in experimental group was 93% ( 27 cases ) , which was higher than that in control group (90%, 28 cases), there was no statistical difference. The vision improvement rate in control group was 86% ( 25 cases ) , compare to 90% ( 28 cases ) in experimental group, there was no statistical differences. CONCLUSlON: No statistical differences showed in visual acuity improvement and the once retinal reattachment rate between the two groups for rhegmatogenous retinal detachment. However, it is believed that external approach microsurgery could be faster, easier to learn with satisfactory effect.

Objective: To establish an animal model for research of maxillary protraction. Methods: 16 pubertal rabbits were assigned randomly to 2 groups. Titanium bone markers were fixed on each side of mucogingival junction, 1 cm above incisor teeth. The experimental group underwent maxillary protraction by self-made distraction devices. A down and forward elastic force (about 3.43 N) was exerted for 30 days. Results: In 30 d, the distance of premaxilla movement in the experimental group was 1.89 mm averagely, while that in the control group was only 0.11 mm. Cephalometric analysis indicated that the maxilla of rabbits was moved forward obviously by appliance in the experimental group, and maxilla was not rotated. There was no obvious difference between the control and the experimental groups. Conclusion: Animal model used in this experiment for maxillary protraction is reliable. The appliance can move the rabbits maxilla forward obviously during the maxillary protraction.

OBJECTIVETo observe interventional effects of anti-viral therapy and Compound Qin-gre Granule (CQG) on host cellular immune functions of acute virus infection patients.

METHODSThirty acute virus infection patients were recruited to detect peripheral lymphocyte subsets. They were randomly assigned to two groups, the Western medicine treatment group (treated with anti-virus Western medicine) and the integrative medicine treatment group (treated with anti-virus Western medicine plus CQG). T-cell subsets were re-examined 7 days later. Changes between before and after treatment were observed. Effect on host cellular immune functions and efficacy were compared between the Western medicine treatment and the integrative medicine treatment.

RESULTSCompared with the normal control group, the percentage of peripheral T cells increased, and the percentage of B/NK cells decreased in acute virus infection patients (P < 0.01). Meanwhile, in T cell subsets, the percentage of CD8+ T cells and CD8+ CD38+ T cells increased (P < 0.05, P < 0.01); and percentages of CD4+ T cells, CD4+ CD28 + T cells, and CD8+ CD28+ T cells decreased (P < 0.05, P < 0.01). After one-week treatment, percentages of CD4+ T cells, CD4+ CD28+ T cells, and CD8+ CD28+ T cells increased (P < 0.05, P < 0.01), while the percentage of CD8+ CD38+ T cells decreased (P < 0.01). More significantly, these changes were greater in the integrative medicine treatment group than in the Western medicine treatment group (P < 0.05).

CONCLUSIONSDisarranged cellular immune functions existed in acute virus infection patients. CQG could significantly improve viral infection induced immunologic derangement and immunologic injury.

Objective To investigate the effect of intraocular injection of mixed crystalline in vivo on survival of retinal ganglion cells(RGCs)after optic nerve cut.Methods Twenty Long-Evens rats were divided into normal control,and 7 day,14 day,and 21 day groups after optic nerve was cut off.There were 5 eyes in each group.Mixed crystallin(1x10~(-4)g/L)and isotonic saline solution were injected into the vitreous of fight eye and left eye respectively.The number of RGCs was counted 7,14 and 21 days after optic nerve cut.Results The density of RGCs declined clearly 7 days after optic nerve cut.In the group with crystallin injection,the density of RGCs declined to 71%,32% and 15% of the control group repec- tively,much higher than that of the controls on days 7,14 and 21 after optic nerve was cut off(P

Objective To determine the frequency of polymorphism at exon 26 (C3435T) of muhidrug resistance 1 gene (MDR1) in epileptic patients in the southern Chinese and to study the association of this polymorphism with pharmacoresistance.Methods DNA samples were obtained from 134 patients,of whom 72 were resistant to antiepileptic drug treatment and 62 were responsive to the treatment. Genotypes of the C3435T polymorphism were determined by polymerase chain reaction (PCR) followed by restriction digestion and gel electrophoresis.Genotype and allele frequencies in the drug resistant group were compared to those in the response group by Chi-square analysis.Results Of all 134 patients,33 (24.6%) had CC genotype,72 (53.7%) had CT genotype,and 29 (21.6%) had TT genotype.The frequency of CC genotype was significantly higher in the pharmaeoresistance group (33.3%) than that in the responsive group (14.5%,P=0.012).The frequency of the C allele was also significantly higher in the pharmacoresistance group (57.6%) than that in the responsive group (44.4%,P=0.03).When patients were divided by types of seizure into three groups:generalized seizure group,partial seizure group,and undefined seizure group,the CC genotype and C allele were associated with pharmacoresistance in the partial seizure group.Conclusions In the southern Chinese,the CC genotype and C allele are associated with resistance to the antiepileptic treatment.This finding needs to be verified in studies with larger sample size.

1.0,achieved the standard request of Disinfection Technology standard.RESULTS Through EOW disinfection,the bacteria were not found on the object surfac of transports and conformed to the object surface disinfection request of Disinfection Technology Standard.CONCLUSIONS Applying EOW to disinfection of polluted instrument recycling vehicle for clinical purpose can fulfill the State standards completely;EOW has strongly germicidal activity,also with characteristics as rapidity,safety and environment security,without any irritant odor.These results indicate a widely potential use of EOW as in hospital disinfection supply center,especially,with a positive significance in health care for pediatric patients.

A P2P technology-based personal digital library sharing model, MIPDLM, was established using the P2 P technology according to the decentralized characteristics of personal digital library in order to improve the per-sonal digital library sharing, in which the topology remodeling was studied according to the interest clusters in per-sonal digital library. The searched messages are constantly transmitted to personal digital library with a high interest similarity, which can thus reduce the searching scope. Simulation experiment showed that MIPDLM could improve the successful searching rate, reduce the average path length, and increase the location rate of resources.

ObjectiveTo systematically and objectively evaluate the therapeutic efficacy of comprehensive acupuncture treatment in managing wet age-related macular degeneration (ARMD), and to seek a standard acupuncture protocol for this disease, for promoting the application in clinic.MethodTotally 37 patients (67 eyes) were observed to compare the vision, Amsler grid and rating scale of quality of life for visual impairment before and after the 3-month treatment. The clinical efficacy was then evaluated. ResultThe vision and score of quality of life were significantly changed after intervention (P<0.05); according to Amsler grid, the total improved rate was 79.2% and the total effective rate was 77.6%; age and disease duration were negatively correlated with the therapeutic efficacy (P<0.05).ConclusionComprehensive acupuncture treatment can significantly improve the vision and quality of life in patients with wet ARMD, and the younger the patients and the shorter the disease duration, the higher the therapeutic efficacy.

Objective To explore the value of shear wave elastography (SWE) in diffuse thyroid disease.Methods The elastic modulus were detected by SWE in 41cases of diffuse thyroid disease [including 16 cases of Graves' disease (GD),16 cases of Hashimoto' s thyroiditis (HT) and 9 cases of subacute thyroiditis(SAT)] and 30 cases of healthy volunteers.The elastic modulus,including Emean,Emin and Emax,were measured and compared.Results Compared with the normal group[Emean(15.7-± 2.5)kPa,Emin(11.6 ± 2.4)kPa and Emax (20.2 ± 3.0)kPa],the Emean[(20.4 ± 4.7)kPa],Emin[(14.4-± 3.8)kPa] and Emax [(27.8 ± 7.3)kPa] of GD,the Emean [(18.4-± 5.0)kPa] and Emax [(25.2 ± 5.8)kPa] of HT,and the Emean[(11.0 ± 2.9)kPa] and Emin [(6.0 ± 2.7)kPa] of the SAT were different significantly(P =0.001,0.007,0.001 ; P =0.045,0.001 ; P =0.000,0.000).There were significant differences between the SAT and the other two groups,namely GD and HT (P ＜0.05).Such differences,however,were not found between GD and HT (P ＞0.05).Conclusions SWE can be used to measure the elastic modulus of the thyroid tissue quantitatively and objectively,serving as a useful technique to predict the diffuse thyroid disease.
