BACKGROUND:For patients with lumbar spondylolisthesis combined with osteoporosis, appropriate fixation system for effective reset and good fixation stability is currently a hot issue of clinical concern. Pedicle screw screw-rod system after bone cement perfusion can achieve the effective fixation between pedicle screw system and the vertebral bone. OBJECTIVE:To observe the therapeutic effect of bone cement-augmented pedicle screw on patients with lumbar spondylolisthesis combined with osteoporosis. METHODS:17 cases of lumbar spondylolisthesis combined with osteoporosis were identified by bone density test. They received the posterior open reduction and internal fixation, and implanted with 68 bone cement-augmented pedicle screws. Their repair effects were observed by short-term fol ow-up. Patients were evaluated using low back pain Visual Analog Scale and lower limb Oswestry Disability Index before treatment, 1 week, 3 months and 1 year after treatment. Vertebral height, intervertebral height, screw loosening and bone cement leakage were observed using imaging.
RESULTS AND CONCLUSION:Compared with pre-treatment, low back pain Visual Analog Scale score and lower limb Oswestry Disability Index were significantly improved at 1 week, 3 months and 1 year after treatment (P<0.05). No significant difference was detected between post-treatment and fol ow-up (P>0.05), which indicated that clinical repair effect could be effectively maintained. At 3 months of fol ow-up, one screw loosening occurred in two patients. During fixation, mild bone cement leakage appeared in seven vertebral bodies with screw fixation, no symptoms or subsequent complications were observed. There were no significant differences in vertebral height and intervertebral height before and after treatment and during fol ow-up (P>0.05). These results suggest that bone cement-augmented pedicle screw for patients with lumbar spondylolisthesis combined with osteoporosis can effectively reset vertebral slippage, effectively provide good anti-pul-out force for a long term, and the effect was stable. Bone cement augmentation can perfectly strengthen fixation, shows good biocompatibility, and avoids osteoporosis around the screw-induced failure fixation.

OBJECTIVETo investigate the effects of recombinant human growth hormone on serum lipid in aged male patients with chronic heart failure (CHF).

METHODSEighty seven patients with chronic heart failure(> or = 60 years old) were randomly divided into 2 groups: the CHF control group (n = 46) who received regular therapy and the CHF experimental group (n = 41) who received regular therapy and recombinant human growth hormone. The treatment would be continued for 3 months. Another group was normal control group (n = 10). The detection of serum growth hormone (GH), insulin-like growth factor (IGF-1), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) was carried out before and after treatment in the participants.

RESULTSBefore treatment, the levels of GH and IGF-1 were not significantly different among groups. After treatment, the levels of GH (0.71 +/- 0.34 vs 0.96 +/- 0.48) and IGF-1 (95.64 +/- 21.11 vs 111.64 +/- 23.14)in CHF experimental group were higher than those before the treatment. In CHF control group, the levels of GH(0.81 +/- 0.32 vs 0.79 +/- 0.29) and IGF-1 (97.82 +/- 19.74 vs 99.65 +/- 20.11) had no significant change after the treatment. After treatment, the levels of GH (0.96 +/- 0.48 vs 0.79 +/- 0.29) and IGF-1 (111.64 +/- 23.14 vs 99.65 +/- 20.11) in CHF experimental group were higher compared with that of CHF control group. Before treatment, the serum levels of LDL-C, HDL-C, TC and TG had no significant difference among groups. After treatment,the levels of LDL-C (2.11 +/- 0.82 vs 1.76 +/- 0.51) and TC (3.78 +/- 1.34 vs 3.21 +/- 1.17) in CHF experimental group were lower than those before the treatment. However, the levels of HDL-C (1.10 +/- 0.31 vs 0.99 +/- 0.28)and TG (1. 89 +/- 1.07 vs 1.66 +/- 0.95) had no significant change after the treatment compared with before treatment. In CHF control group, the serum lipid levels had no significant change after the treatment.

CONCLUSIONAs the treatment of rhGH for aged male patients with chronic heart failure, GH influences lipid metabolism, which reduces the level of LDL-C, TC. However GH has no effects on the serum HDL-C and TG level. With the treatment of rhGH for long-term, lipid metabolism should be paid attention,and the treatment for blood lipid reduction should be adjusted in time.

Objective To study association of hepatitis B virus(HBV) precore (pre c)/basic core promoter(BCP) mutations with the genotype or the progression of liver disease. Methods The serum samples from 148 patients with HBV-relative diseases were collected, including 31 asymptomatic carriers, 32 with chronic hepatitis B (CHB), 40 with liver cirrhosis(LC) and 45 with hepatocellular carcinoma(HCC). The genes covering HBV pre c and BCP were amplified by nested polymerase chain reaction (nPCR). The PCR products were subjected to direct sequencing and the mutations in pre c 1896 and BCP 1762/1764 were determined by sequence analysis. HBV genotypes were also detected in the sera by restriction fragment length polymorphism based on S-gene PCR products. Results Of 148 serum samples of HBV, 128 were successfully genotyped and sequenced. There were 60 genotype B and 68 genotype C. The mutation in pre c (A1896) was significantly higher in genotype B than in genotype C (48.3% vs 29.34%, P

Objective To investigate the relationship between serum levels of CA15-3, CA-125 and CEA in postoperative breast cancer patients and clinicopathological parameters and pathogenetic condition turnover. Methods From January 2004 to December 2007, 219 breast disease cases with integrity clinical information, admitted to general surgery and oncology department of Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, were collected. The serum concentrations of CA15-3, CA-125 and CEA were determined by chemiluminescent immunoassay(CLIA). Wilcoxon Kruskal Wallis analysis, crosstable analysis and spearman correlation analysis were used to investigate the association between the serum concentration and clinical parameters and pathogenetic condition turnover. Results The serum concentrations of CA15-3,CA-125 and CEA in metastatic breast cancer group were significantly higher than those in nonmetastatic group(P=0.000). The sensitivity of the 3 tumor markers in combination was 64.1% in metastatic breast cancer diagnosis. CA15-3 and CA-125 at the time of initial metastasis were correlated with estrogen receptor state(PCA15-3=0.039, PCA-125=0.049). The level of 3 tumor markers in multiorgan metastatic group were significantly higher than those in single organ metastastic patients(P=0.000). There were significant differences between the levels of CA15-3 and CEA in distant metastatic group and those in local metastatic group (PCA15-3=0.001,PCEA=0.022). Conclusion The high serum concentrations of CA15-3,CEA and CA-125 were useful in monitoring the metastasis. The high serum levels of CA15-3 and/or CA-125 may indicate that the patients will be more sensitive to endocrine therapy.
