AIM:To compare the refractive errors measured by the VISX WaveScan, OPD - Scan Ⅲ and the subjective refraction.
METHODS: Seventy - six patients ( 152 eyes ) were recruited from January 2013 to December 2013. All patients were measured with subjective refraction by the phoropter (NIDEK, RT-5100), objective refraction by the WaveScan ( AMO Company, USA) , OPD-ScanⅢ ( Nidek Technologies, Japan). The sphere, cylinder, axis of the three methods were compared and analyzed.
RESULTS: The sphere measured by WaveScan was lower than that by subjective refraction, the difference was 0. 13±0. 30D (t=3. 753, P<0. 001). For cylinder, the difference was 0. 13±0. 43D (t=3. 664, P<0. 001). There was no significance for sphere, cylinder, and spherical equivalent between OPD - Scan Ⅲ and subjective refraction (P>0. 05). The value of the difference between WaveScan and subjective refraction was 5. 87o±6. 19o for the axis and the difference between OPD-Scan Ⅲ and subjective refraction was 3. 82o±3. 95o. There was statistic significance (t=2. 817, P=0. 006).
CONCLUSION: For sphere and cylinder, WaveScan generated some deviation relative to subjective refraction. The Nidek OPD-ScanⅢ gives more accurate measures of objective refraction when compared with subjective refraction.

Cervical spondylotic myelopathy (CSM) is a common cause of spinal cord dysfunction clinical disease. Surgery is the main therapeutic tool for CSM. However, there are obvious differences in clinical functional recovery after operation. For the past few years, the influence factors of prognosis in cervical spondylosis myelopathic has been widely concerned. Age, nerve function, course of desease, imaging findings,surgical method and related factors became the investigative point for prognosis of cervical spondylotic myelopathy. Present viewpoint showed that the older patient, preoperative worse nerve function, longer the course of disease would result in worse outcomes. Imaging examination maybe can indicate the prognosis, but the correlation is unclear. Selection of surgical method and approach should be based on the principles of sufficient decompression, stabilize the alignment of the cervical spine, keeping backward extension of cervical spine, maintain effective decompression, preventing complications. Therefore, the treatment of cervical spondylotic myelopathy should be on the basis of pathogenic condition and imaging examination at early stage and a suitable usrgical procedure should be performed to obtain a better prognosis.

BACKGROUNDThe Taq/B, Msp/ and I405V polymorphisms of cholesteryl ester transfer protein (CETP), an important regulatory factor of lipid metabolism, have been attracted much more attention by the researchers. In this study, we investigated the associations between these 3 polymorphisms of CETP gene and variations in plasma lipid and lipoprotein levels in patients with coronary heart disease (CHD).
METHODSGenomic DNA was extracted from leukocytes of 203 CHD patients and 100 control subjects using the salting out method. Genotyping of the CETP gene was performed using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) techniques. Statistical analysis was conducted using the SPSS 10.0 software package.
RESULTSThe distribution of allele and genotype frequencies of the Taq/B, MspI, and I405V polymorphisms was similar in the CHD patient group and the control group. The B1B1 genotype of the Taq/B polymorphism was associated with significantly higher TC (P=0.039) and LDL-C (P=0.044) levels than the B2B2 genotype in CHD patients, and with significantly higher LDL-C (P=0.034) levels than the B2B2 genotype in controls. Homozygotes of the I405V polymorphism exhibited significantly higher HDL-C levels than VV homozygotes among control subjects (P=0.023). In male CHD patients with unambiguously assigned haplotypes, B2-M2-V/B2-M2-I patients demonstrated significantly higher HDL-C concentrations than B1-M2-V/B1-M2-I (P=0.023) and B1-M2-V/B1-M2-V patients (P=0.047).
CONCLUSIONSGenetic variations in the CETP gene may account for a significant proportion of the differences in plasma lipid and lipoprotein concentrations among the general population. The B1B1 genotype of the Taq/B polymorphism is probably a genetic risk factor for CHD in the study population.

Objective To observe the effect of T-2 toxin on growth and development of rat epiphyseal plate of left knee and metaphyseal bone of femur and tibia in normal and low nutritional status, to find out possible pathogenic factors of Kashin-Beck disease and provide experimental basis for early intervention. Methods Ninety 3-week-old Wistar rats, weighing 60 - 70 g, were randomly divided into three groups: control group(general feed), T-2 toxin + general feed group, T-2 toxin + low nutrition feed group, thirty rats in each group with equally sex ratio. T-2 toxin (1.0 mg/kg) was administered orally 5 times a week via a gavage needle for 4 weeks. The change of hair, activity and body weight was observed. After 1, 2, 4 weeks, the epiphyseal plate of left knee and metaphyseal bone of femur and tibia (including distal femur and proximal tibia) were collected. Specimens were processed with HE and Masson staining. The morphology of chondrocytes and matrix collagen content in epiphyseal plate was observed. Trabecular bone volume fraction in tibial metaphyseal bone was analyzed by Image-Pro Plus 6.0 software. Results In the control group, rats were in good movement and hair with light, but in T-2 toxin + general feed group and T-2 toxin + low nutrition feed group, rats were found with reduced activities and hair with dark color. Body weights(g) of the control group, the T-2 toxin + general feed group and the T-2 toxin + low nutrition feed group were 81.0 ± 6.2, 79.0 ±5.1, 77.0 ± 7.5, respectively, by the end of first week; 101.8 ± 6.7, 97.0 ± 6.8, 93.0 ± 5.3, respectively, by the end of second week; 151.1 ± 15.7, 126.5 ± 11.9, 106.5 ± 11.5, respectively, by the end of fourth week. There was significant difference in groups by second week and the fourth week (F = 9.72, 41.65, all P < 0.05 ). There was significant difference among multi-groups by the fourth week(all P < 0.01 ). Under light microscope, at the second weeks, coagulative necrosis of chondrocytes was found in hypertrophic zone in the two groups with T-2 toxin; at the fourth weeks, cell necrosis increased. Masson staining showed collagen staining in the two groups with T-2 toxin significantly turned to clear pale coloration, indicating that the collagen matrix was significantly reduced. Image analysis showed there was significant difference in groups at the second and fourth week(F= 9.72, 41.65, all P< 0.05)in tibial metaphyseal trabecular bone volume fraction. There was significant difference between T-2 toxin + low nutrition feed group[(0.55 ± 0.12)%, (0.21 ± 0.0)%] and control group[(0.67 ± 0.09)%, (0.51 ± 0.14)%] by the second and fourth week(all P < 0.01 ). Conclusions Under normal nutritional status, T-2 toxin can induce hypertrophic epiphyseal cartilage necrosis, collagen content decreased in epiphyseal plate, metaphyseal trabecular bone formation disorders; in the low nutritional status, T-2 toxin can lead to rat epiphyseal necrosis and significant metaphyseal bone disorder, but whether the performance is related to Kaschin-Beck disease needs to be studied further.

OBJECTIVETo investigate the incidence and variation of tunnel enlargement after anterior cruciate ligament (ACL) reconstruction with peroneus longus muscle combined with BMP and allogeneic bone.
METHODSACL reconstructions with peroneus longus muscle combined with BMP and allogeneic bone were performed in 18 patients (18 knees)in the study from March 2007 to July 2009. Among the patients,14 patients were male and 4 patients were female, ranging in age from 21 to 47 years, with an average of 35.5 years. Twelve patients had the injuries in the right knee and 6 patients in the left knee. The CT scans were taken in a consistent manner at the 1st week and the 3rd, 6th, 12th months after surgery to measure tibial and femoral tunnel expansion.
RESULTSTunnel enlargement didn't happen in 18 knees. The average enlargement of 18 cases of femoral tunnel was (1.10 +/- 0.42) mm; and the average enlargement of 18 cases of tibial tunnel was (1.00 +/- 0.51) mm. There was statistical significance of femoral tunnel between the 1st week and the 3rd month after surgery (P < 0.05); and there were no significant difference of the tunnel diameters among the 3rd, 6th, and the 24th months postoperatively (P > 0.05). There was statistical significance of tibial tunnel between the 1st week and the 3rd month after surgery (P < 0.05); there were no significant differences of the tunnel diameters among the 3rd, 6th, and 24th months postoperatively (P > 0.05).
CONCLUSIONAnterior cruciate ligament reconstruction with peroneus longus muscle combined with BMP and allogeneic bone could obviously reduce the incidence of tunnel enlargement. The tunnel diameter obviously increase in 3 months after surgery,and it remains basically unchanged later.

OBJECTIVETo discuss the clinical results of hook plate internal fixation for the treatment of distal traumatic injuries of clavicle,and to analysis the mechanism of the complications.
METHODSFrom 2001.9 to 2008.2, 36 patients with fresh distal clavicle fractures of Neer type II and 14 patients with dislocation of Acromioclavicular joint of Tossy type III were treated with hook plate internal fixations. Among the patients, 36 patients were male and 14 patients were female, ranging in age from 19 to 77 years, with an average of 43 years. After the operation, the range of motion of shoulder joint was measured and the complications were studied. The Karlsson and Constant-Murley criteria were used to evaluate the therapeutic effects.
RESULTSAll the patients were followed up with a mean duration of 12 months (7 to 18 months). All the patients could move shoulder joint actively 1 week after operation, and recover to the normal ROM at the 6th week after operation. According to Karlsson criteria, 44 patients got an excellent result, 6 good. According to Constant-Murley criteria, the average score of wound shoulder was (73.8 +/- 8.3) before operation, and (59.6 +/- 6.7) after operation, and the postoperative score was higher than preoperative score. No incision infections were found and 5 patients with complications were cured. No re-dislocation of acromioclavicular joint occurred.
CONCLUSIONIt is advocated that hook plate for the treatment of distal clavicular fractures of Neer type II and acromioclavicular dislocation of Tossy type III could provide sufficient stability to allow early functional rehabilitation, and to decrease the rate of complications.

OBJECTIVETo determine the expression of nerve growth factor (NGF) in hepatic tissues and serum of patients with primary liver cancer (PLC), and to investigate the relationship of serum NGF levels with clinicopathological features of PLC.
METHODSHepatocellular carcinoma (HCC) samples and patient-matched tumor-adjacent liver samples were collected from 26 PLC patients to assess the mRNA and protein expressions of NGF by reverse transcription-PCR, western blotting (b-actin normalized), and immunohistochemistry. In addition, serum samples were collected from 40 PLC patients, 40 liver cirrhosis patients, 40 chronic hepatitis patients (including hepatitis B or C virus infections), and 30 healthy (normal) controls. The serum levels of NGF were measured by enzyme-linked immunosorbent assay. Intergroup differences were assessed by the t-test, and correlation with sex, age, presence of cirrhosis, tumor size, and TNM classification were assessed by the Kruskal-Wallis H test followed the Mann-Whitney U test.
RESULTSHCC tissues showed higher mRNA and protein expressions of NGF than the corresponding tumor-adjacent non-HCC tissues. Hepatic NGF expression was mainly localized to the tumor cell cytoplasm. Serum NGF expression was significantly higher in PLC patients (33.86+/-16.11 pg/ml) and cirrhosis patients (20.57+/-9.73 pg/ml) than in normal controls (11.13+/-6.12 pg/ml) and chronic hepatitis patients (13.20+/-6.23 pg/ml) (P less than 0.01). Furthermore, when the PLC patients were stratified according to tumor size and TNM stage, the serum NGF level was found to be significantly higher in patients with tumors more than 5 cm (vs. less than 5 cm; U=83.000, P=0.002) or of TNM stage III/IV (vs. stage I/II; U=103.500, P=0.009).
CONCLUSIONElevated expression of NGF in liver cancer tissues and serum of PLC patients is related with tumor size and TNM staging. These findings suggest that NGF may play a role in HCC tumorigenesis and/or that serum NGF may represent a prognostic marker of PLC.
