ABSTRACT

BACKGROUND: Kyphoplasty with bone cement injection for the treatment of osteoporotic vertebral compression fractures has a good clinical effect, but it is unclear whether there is a difference in the efficacy on the fractures in different parts of the spine. OBJECTIVE: To compare the outcomes of kyphoplasty with bone cement injection in the treatment of osteoporotic vertebral compression fractures in different parts of the spine. METHODS: We retrospectively analyzed the clinical data of 247 cases of single-segmental osteoporotic vertebral compression fractures undergoing kyphoplasty with bone cement injection at the Department of Orthopaedic Surgery, the First Affiliated Hospital of Soochow University in China from January 2011 to August 2014. There were 24 cases of upper and middle thoracic (T1-T10) fractures, 187 cases of thoracolumbar (T11-L2) fractures and 36 cases of lower lumbar (L3-L5) fractures. The surgical time, X-ray exposure time, bone cement volume and leakage, the Visual Analog Scale score, the Oswestry Disability Index score, anterior vertebral height ratio and Cobb angle were assessed preoperatively, at 1 day posteroperatively and at the final visit. RESULTS AND CONCLUSION: (1) All patients underwent the surgery successfully, and were followed up for 12-44 months, with an average of (25.44±7.85) months. (2) There were 18 cases of bone cement leakage in the three groups, including 3 (12.5%) cases of upper and middle thoracic fractures, 13 (6.4%) cases of thoracolumbar fractures and 2 (5.6%) cases of lower lumbar fractures. (3) The surgical time and X-ray exposure time were significantly higher in the patients with upper and middle thoracic fractures than those with thoracolumbar fractures or lower lumbar fractures (P < 0.05) , while the volume of bone cement was significantly lower than that in the other two groups (P < 0.05) . Additionally, there were no significant differences in the surgical time, X-ray exposure time, and amount of bone cement between the patients with thoracolumbar fractures and with lower lumbar fractures (P> 0.05) . (4) There were no significant differences in the Visual Analog Scale score, Oswestry Disability Index score, anterior vertebral height ratio and Cobb angle among the three groups preoperatively, at 1 day postoperatively and at the final visit (all P> 0.05) . However, compared with baseline, these indicators were significantly improved in each group at 1 day postoperatively and at the final visit (P < 0.05) . (5) To conclude, kyphoplasty with bone cement injection has achieved satisfactory outcomes in the treatment of osteoporotic vertebral compression fractures in different parts of the spine.

ABSTRACT

The loss of endothelial connective integrity and endothelial barrier dysfunction can lead to increased vascular injury, which is related to the activation of endothelial inflammasomes. There are evidences that low concentrations of aspirin can effectively prevent cardiovascular diseases. We hypothesized that low-dose aspirin could ameliorate endothelial injury by inhibiting the activation of NLRP3 inflammasomes and ultimately prevent cardiovascular diseases. Microvascular endothelial cells were stimulated by lipopolysaccharide (2 μg/mL) and administrated by 0.1-2 mmol/L aspirin. The wild type mice were stimulated with LPS (100 μg/kg/day), and 1 h later treated with aspirin (12.5, 62.5, or 125 mg/kg/day) and dexamethasone (0.0182 mg/kg/day) for 7 days. Plasma and heart were harvested for measurement of ELISA and immunofluorescence analyses. We found that aspirin could inhibit NLRP3 inflammasome formation and activation in dose-dependent manner and has correlation between the NLRP3 inflammasome and the ROS/TXNIP pathway. We also found that low-concentration aspirin could inhibit the formation and activation of NLRP3 inflammasome and restore the expression of the endothelial tight junction protein zonula occludens-1/2 (ZO1/2). We assume that aspirin can ameliorate the endothelial layer dysfunction by suppressing the activation of NLRP3 inflammasome.

ABSTRACT

Objective To study epidemiological characteristics of thelazjasis, in Zunyi and surrounding areas, morphology and 18S rRNA gene sequence of Thelazia callipaeda. Methods The Thelazia callipaeda was collected from several hospitals, including affiliated Hospital of Zunyi Medical College and Zunyi Aerospace Hospital, in Zunyi region since 2011 to 2015. Clinical data of infected human thelaziasis, including the patients' gender, age, residence and pets such as cats or dogs, were analyzed to find out the factors influencing the incidence. Morphology characteristics of female and male Thelazia callipaeda were observed under microscope. 18S rRNA gene of Zunyi Thelazia callipaeda was amplified by PCR, and the evolutional relationship was analyzed through the software MEGA 7.01 based on neighbour-joining (NJ) method. Homology was campared with 18S rRNA gene from GenBank in National Center of Biotechnology. Results Totally 25 cases had been reported during the study, of which 22 cases had more details. Based on the cases, we found the thelaziasis was increasing year by year. For instance, 2 cases (9.1%) were reported in 2011, 1 case (4.5%) in 2012, 3 cases in 2013 (13.6%), 10 cases (45.5%) in 2014 and 6 cases (27.3%) in 2015 . During the five years , totally 15 cases were treated between August and November, when the human thelaziasis was in typical epidemic peaks. We analyzed characteristics of the total cases reported to date. Most of the cases occurred in rural areas (20 cases). Majority of patients lived in rural region. And most cases were between 30 to 60 years old, indicating no age limit, especially, there were two cases who were at the ages of 8.5 months and 77 years old, respectively. Moreover, more women suffered from the disease than that in men, of which, the case number was 16 in women and 6 in men, and there were 7 cases who had cats or dogs at home. Under light microscope, the edge of Thelazia callipaeda had serrated cuticle with transverse striations. And male worm had a sharp peak at the tail end of Thelazia callipaeda, which cured to the ventrite and had two copulatory spicules, long one and short one, respectively. While female worm had a blunt tail, containing numerous eggs and rounded first-stage larvaes in a single line in the distal area of the uterus, near the vulva. Sequences of Thelazia callipaeda 18S rRNA gene from Zunyi and Oita Japan (AB538282.1) were showed homology of 100%, and they were clustered in a same branch of Phylogenetic tree. Conclusions Human thelaziasis cases in Zunyi region are increasing each year, and most of the cases have occurred in rural areas. 18S rRNA gene has a high homology with sequence AB538282.1 in Thelazia callipaeda. Combining clinical data, analysis of epidemiological characteristics and the characteristics of 18S rRNA should be good for specie identification and epidemiological analysis.

ABSTRACT

Objective To study the protective effect of a mixed recombinant Bifidobacterium (Bb) vaccine of Taenia solium in piglets. Methods Healthy piglets of 40 days old were randomly divided into experimental group and control group, 4 in each group. Experimental group was given 1011 CFU rBb-TSO45W-4B vaccine and rBb-TSOL18 vaccine (in the ratio of 1 : 1). Control group was given Bb liquid medium (MRS). A total of two times of immunization were conducted, once for every two weeks. At different time points after immunization, the serum was separated from precaval vein blood to detect the level of IgG by enzyme linked immunosorbent assay (ELISA). Piglets were challenged with Taenia solium eggs on the 4th week after the last immunization and killed 3 months after infection. The cysticerci were separated to count and calculate the reduction rate of cysticerci. Blood from precaval vein was collected to separate serum and prepare peripheral blood lymphocytes (PBMC). The levels of IgG,IgG1 and IgG2a in serum sampl es and the levels of interleukin ( IL )-2 , interferon (IFN)-γ, IL-4 and IL-10 in PBMC culture supernatant were determined by ELISA. The level of PBMC proliferation was tested using methyltetrazolium (MTT) assay. Results In experimental group, the level of serum IgG increased from the 2nd to the 8th weeks after immunization, and reached the highest level on the 4th week after immunization (mg/L:270 . 64 ± 1 . 94 vs 207.74 ± 2.24, t=42.479, P<0.05). Reduction rate of cysticercus was 80.48%. Compared with control group, the levels of IgG and IgG2a in serum were significantly increased, while the level of IgG1 was significantly decreased (mg/L: 364.15 ± 11.52 vs 245.94 ± 8.81, 89.74 ± 1.13 vs 62.61 ± 0.84, 20.52 ± 1.00 vs 34.11 ± 0.65, t=16.303, 38.579, - 22.772, P < 0.05). The levels of IL-2 and IFN-γ in PBMC culture supernatant were significantly increased, while the levels of IL-4 and IL-10 were significantly decreased (ng/L:215.24 ± 3.31 vs 174.19 ± 2.14, 28.21 ± 0.27 vs 17.69 ± 0.28, 40.35 ± 0.34 vs 52.57 ± 0.29, 71.34 ± 0.36 vs 94.82 ± 0.45, t =20.839, 53.623,-54.743,- 81.266, P<0.05). The level of PBMC proliferation was significantly increased (0.620 ± 0.051 vs 0.242 ± 0.053, t=10.259, P<0.05). Conclusions It is concluded that the mixed rBb vaccine of Taenia solium might give piglets a certain protection. Th1 type immune response plays an important role in the protection.

ABSTRACT

BACKGROUND:The posterior lumbar interbody fusion is one of the effective methods for the treatment of lumbar and sacral spine diseases. Most surgeons fix the cage by compressing the disc space in order to keep stability and prevent dislodgement. However, some surgeons think that the non-compression technique does favor for increasing of the disc and foraminal height and thus improving the clinical outcomes, and does not increase the risk of fusion shift. OBJECTIVE:To compare the effects in fixing the cage by the compression and non-compression techniques on posterior lumbar interbody fusion. METHODS:Data of 64 patients with single-segment lumbar degeneration undergoing posterior lumbar interbody fusion between August 2009 and June 2014 were retrospectively analyzed. Fusion device was fixed according to compression of intervertebral space. These patients were divided into compression group (n=30) and non-compression group (n=34). RESULTS AND CONCLUSION:(1) Curative effects:Lumbar and leg pain visual analogue score, Oswestry disability index, SF-36 score and the height of intervertebral space, intervertebral foramen height and lumbar lordosis were significantly improved postoperatively in each group compared with preoperatively (P0.05). (3) Correlation analysis:The increase of the intervertebral space and the height of the intervertebral foramen were not significantly correlated with the improvement of the clinical curative effect (P>0.05). (4) Test results demonstrated that outcomes of the compression technique to fix the cage are equivalent to the non-compression in posterior lumbar interbody fusion. Non-compression is advantageous to increase the intervertebral space and the height of the intervertebral foramen. Both of them are conducive to the recovery of lumbar lordosis, but are not correlated with the increase in clinical curative effect.

ABSTRACT

BACKGROUND:The patients undergoing lumbar discectomy have a higher risk of recurrence. There are many different ways of reoperation, but there are few studies on spine-pelvis sagittal morphology of patients with recurrent lumbar disc herniation. OBJECTIVE:To compare the effect of discectomy and posterior lumbar interbody fusion on spine-pelvis sagittal morphology of patients with recurrent lumbar disc herniation. METHODS:Sixty-one patients of recurrent lumbar disc herniation after discectomy were divided into discectomy group (n=30) and posterior lumbar interbody fusion group (n=31) according to the re-repair method. The height of intervertebral disc, lumbar lordosis and pelvic projection angle in the two groups before and after treatment were measured and compared based on standing spine lateral X-ray images. RESULTS AND CONCLUSION: After treatment, the height of intervertebral disc, lumbar lordosis and pelvic projection angle of patients in discectomy group were not significantly changed compared with before treatment (P> 0.05). After treatment, the height of intervertebral disc, lumbar lordosis and pelvic projection angle of patients in posterior lumbar interbody fusion group were significantly increased compared with those before treatment (P 0.05).After treatment, the height of intervertebral disc, lumbar lordosis and pelvic pelvic projection angle were significantly increased in the posterior lumbar interbody fusion group compared with the discectomy group (P < 0.05). These results demonstrate that discectomy cannot significantly change the spine-pelvis sagittal morphology of patients subjected to re-operation, but compared with the discectomy treatment, posterior lumbar interbody fusion has a greater impact on spine-pelvis sagittal morphology of patients subjected to re-operation.

ABSTRACT

BACKGROUND:Studies have shown that morphological characteristics of iliolumbar ligament are controversial. Few Chinese studies concerned anatomical structure and biomechanical features of Chinese iliolumbar ligament, and no detail statistical data were found. OBJECTIVE: To study the relationship of L5/S1 disc herniation and the L5 spondylolisthesis with iliolumbar ligament. METHODS: A total of 28 cases receiving health examination, 26 patients with L5/S1 disc herniation and 26 patients with L5 spondylolisthesis were recruited from First Affiliated Hospital of Soochow University in China in 2013. Normal group contained 9 males and 19 females. L5/S1 disc herniation group contained 14 males and 12 females. L5 spondylolisthesis group contained 7 males and 19 females. Of them, there were 13 cases of spondylolysis and 13 cases degenerative spondylolisthesis; as wel as 24 cases with degree I spondylolisthesis and 2 cases of degree II spondylolisthesis. The relative widths of the L5 transverse process (RT value) on the X-ray of the lumbar vertebra of each case were measured and calculated. RESULTS AND CONCLUSION: No significant difference in age and gender was detected in the normal group, L5/S1 disc herniation group and L5 spondylolisthesis group. RT value was higher in the normal group than in the L5/S1 disc herniation and L5 spondylolisthesis groups (alP=0.000). RT value was greater in the L5/S1 disc herniation group than in the L5 spondylolisthesis group (P=0.000). No significant difference in RT value was detectable between males and females. No significant difference in RT values was visible between the left and right sides. In patients with L5 spondylolisthesis, RT values were lower in the degenerative spondylolisthesis patients than in spondylolysis patients (P=0.004). Results indicated that the strength of iliolumbar ligament in normal person was higher than that with L5/S1 disc herniation and L5 spondylolisthesis. The strength of iliolumbar ligament in L5/S1 disc herniation patients was higher than that with L5 spondylolisthesis patients. The strength of iliolumbar ligament in spondylolysis patients was higher than that with L5 degenerative spondylolisthesis patients. The mechanical strength of iliolumbar ligament was possibly associated with L5/S1 disc herniation and L5 spondylolisthesis.
