ObjectiveTo investigate the correlation between single nucleotide polymorphism (SNP)of complement factor H (CFH) gene and exudative age-related macular degeneration (AMD) susceptibility.MethodsThis is a retrospective case control study. 136 exudative AMD patients (AMD group) and 140age and sex-matched normal subjects (control group) were enrolled in this study. The peripheral blood was collected,polymorphism genotypes and frequency of CFH Y402H(rs1061170),CFH-257C ＞ T (rs3753394) and CFH IVS15 (rs1329428)were measured by polymerase chain reaction (PCR) and allelespecific restriction endonuclease digestion. The SHEsis software was performed on haplotype construction to analyze the frequency.ResultsThere are TT, TC, CC genotypes and T, C allele in CFH Y402H (rs1061170); CC, CT, TT genotypes and C, T allele in CFH-257C＞T (rs3753394); AA, AG, GG genotypes and A, G allele in CFH IVS15 (rs1329428). The differences of genotypes and allele frequency between 2 groups were statistically significant (P＜0. 05). The TC genotype in CFH Y402H, TT genotype in CFH-257C＞T (rs3753394) and GG genotype in CFH IVS15 (rs1329428) were associated with exudative AMD susceptibility (OR=4. 11,2. 55,3.11;P＜0.05). The T, C and G allele were the risk alleles (OR=3.14,1.72,1.79;P＜0. 05). The differences of frequency between TCG, CTG and CTA haplotype were statistically significant(X2 =10.53,6.60, 32.82;P＜0.05). ConclusionThere is correlation between SNPs of CFH gene and exudative AMD susceptibility.

Objective To investigate MRI manifestations of temporomandibular joint trauma,emphasized on the displacement and deformation of the meniscus.Methods Thirteen patients with TMJ trauma were examined by MRI with 3-inch dual surface coils.T1WI and T2WI images in oblique sagittal and coronal plane were acquired in both closed-and open-mouth positions.Results Twenty(20/26,76.9%) joints had condylar fractures.Nineteen(19/20,95%) discs in 12 patients displaced anteromedially with the condylar fragments,six(6/20,30%) discs showed distortion and deformation.The other one patient had unilateral condylar fracture companied with avulsion and lateral dislocation of ipsilateral disc(1/20,5%),and the opposite disc also showed slight anterior displacement.Effusion was observed in 12(12/20,60%) joints with condylar fractures.The location of the discs didn't show obvious change between closed-and open-mouth positions.Conclusion MRI is an effective method for demonstrating TMJ injuries,and is useful for detecting the changes of morphology and position of the discs.

Objective To evaluate the safety and feasibility of hepatic resection for huge primary liver carcinoma (PLC). Methods 216 cases of huge PLCs(mean diameter of 14.2cm) were resected. The hepatectomies were performed under intermittent occlusion of hepatic inflow. Results All 216 cases were successfully resected. The mean time of occlusion of hepatic inflow was 19min, the mean blood loss was 743 ml. No serious complications occurred, and only seven patients died of hepatic failure and upper gastrointestinal haemorrhage postoperatively in this series. Conclusions Although resection of huge PLC is quite difficult, but if suitable surgical techique and perioperative management are adopted ,it is safe and feasible .

Objective To develop a holding mechanism for the drainage bag to reduce the accident rate of tube falling off during CT examination.Methods The mechanism was composed of a bed body,a mobile bed board,a connecting board,a rod and kink section.CT bed board had a sandwich structure with carbon fibre composite and foam material,and the connecting board,kink section,rod and its hinge joint were made of polycarbonate material.Results The mechanism decreased the risk for tube falling off during CT examination and increased the patient comfort.Conclusion The mechanism gains advantages in stability,mobility,convenience and practicability,and thus is worthy promoting practically.

ObjectiveTo investigate the efficacy of combined therapy of mild hypothermia and hibernation to treat severe brain injury. Methods24 patients with severe brain injury were randomly divided into combined therapy group and normothermia group. Glasgow Coma Scale scores of all the patients were in the range of 3 to 8. No later than 10 hours after their injury, hypothermia patients were given half dosage of No.1 hibernation cocktail and had been cooled by cooling blankets to 32℃-34℃ (rectal temperature) for 5 days, then to 35℃ for 24 hours, and slowly increased to their normal level. 3 days and 7 days after their admission, intracranial pressure,creatine phosphate kinase,partial pressure of arterial O2 and CO2, platelet and Na+,K+ were measured.7 days after their admission, Glasgow Outcome Scale scores of each patient and mortality of each group were measured. ResultsThe mortality of combined therapy group(25.0%) was significantly lower than that of normothermia group (66.6%,P<0.05). The decreased values of intracranial pressure, creatine phosphate kinase and platelet number of combined therapy group were all significantly higher than that of normothermia group respectively (P<0.05). There were no significant difference in mean artery pressure, blood electrolyte, and partial pressure of arterial O2 and CO2 between these two groups(P>0.05). ConclusionThe combined therapy of mild hypothermia and hibernation can effectively reduce the mortality of patients with severe brain injury as it is much easier, less invasive and with less complications.

Objective To understand the mechanism of cerebral energy failure after hypoxia ischemia at the molecular level and to establish the protocol for the safe and effective treatment of hypoxic-ischemic encephalopathy(HIE).Methods One hundred neonatal rats were divided into normal control group and hypoxic-ischemic(HI) group. SD rats of both groups were decapitated at the time of 2 h,24 h,48 h,72 h and 7 d after HI.These tissues of cerebrum,cortex and hippocampus were taken out to explore the influence of HI on the expression of GLUT1 and GLUT3 genes with the method of RT-PCR.Results There was an enhancement in the expression of GLUT1 and GLUT3 genes with the increasing of day age. The expression was more intense in hippocampus than that in cortex. However, HI could significantly enhance the expression of GLUT genes. The expression was higher in cortex than that in hippocampus. The expression of two genes reached the peak at 24 h after HI, but was significantly lower than that in control group at 7 d after HI.Conclusion The increased expression of GLUT genes can maintain the energy supplement for the brain and delay a cascade reaction of cerebral energy failure.

Objective: To observe the efficacy of electroacupuncture (EA) plus Yi Jin Jing (Sinew-transforming Qigong Exercises) for knee osteoarthritis (KOA). Methods: A total of 60 patients with KOA were divided into an observation group and a control group according to the random number table method, with 30 cases in each group. Patients in the observation group received the treatment of EA plus Yi Jin Jing (Sinew-transforming Qigong Exercises), while patients in the control group only received EA treatment. Both groups were treated for 5 weeks. The changes of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and visual analog scale (VAS) scores in the two groups were observed after treatment. Results: After treatment, the total effective rate in the observation group (92.3％) was significantly higher than that in the control group (70.0％), (P<0.05); the WOMAC and VAS scores in both groups were significantly lower than those before treatment, showing statistical significance (all P<0.01); there were significant differences in the post-treatment changes in the WOMAC and VAS scores between the two groups (P<0.05, P<0.01). Conclusion: EA plus Yi Jin Jing (Sinew-transforming Qigong Exercises) is clinically effective for KOA. This combined treatment can alleviate clinical symptoms.
