Objective: To investigate the anti-inflammatory effect and the possible mechanism of water and ethanol extracts of propolis. Method: Forty male Wistar rats were divided into 5 groups: normal group, model group, medicine groups, two groups treated with water and ethanol extracts of propolis. The acute pleurisy model was established by injecting carrageenan. The effects of propolis on acute pleurisy was studied by counting leukocytes, measuring the content of MDA, lysozyme and activity of SOD in serum and the content of NO, protein and PGE2 in pleural effusion. Results: The propolis solutions extracted by water and ethanol presented obvious effect on inflammation. It could antagonize the purulent pleurisy, reduce the number of leukocytes and the content of MDA, lysozyme and activity of SOD in serum and the contents of NO, protein and PGE2 and decrease the inflammation. Conclusion: Propolis displays anti-inflammatory effects by decreasing the action of NO and PGE2 and preventing the activation of protein kinase.

AIM: To study the effect of propolis on the expression of CD54 and activation of NF-?B p65 in lung tissue of acute lung injury (ALI) rats. METHODS: 40 male Wistar rats were divided into 5 groups: normal control, model control, dectancyl group, water soluble derivative of propolis (WSP) group and ethanol extracted propolis (EEP) group. ALI animal model was performed by oleic acid and LPS twice attack. The pathologic slice was observed with light microscope and the NF-?B p65 activity and CD54 expression were tested by immunohistochemistry (SABC and SP). RESULTS: Both EEP and WSP antagonized the lung edema, decreased the inflammation and inhibited the expression of CD54 and activation of NF-?B p65. CONCLUSION: The increase in the expression of CD54 and the activation of NF-?B p65 in the lung tissues of ALI were involved in the formation of ALI. Propolis ameliorated the lung damage, which maybe related to the inhibition of CD54 expression and NF-?B p65 activation.

BACKGROUND:Several studies have attempted to apply mouse nerve growth factor to local lesions of peripheral nerve and found that local injection of mouse nerve growth factor can promote nerve recovery, which is superior to systematic application. OBJECTIVE:To evaluate the clinical effects of gelatin sponge infiltrated by mouse nerve growth factor in the repair of peripheral nerve injury. METHODS:Thirty-six patients with single peripheral nerve injury, including 16 males and 20 females, aged 18-48 years, were randomly divided into two groups: 18 patients in case group underwent debridement and neuroanastomosis, and then the injured nerve was wrapped by gelatin sponge which was infiltrated by mouse nerve growth factor and folowed by plaster fixation, anti-inflammatory therapy, neurotrophy and circulation improvement therapy; the other 18 patients in control group were treated only with debridement and neuroanastomosis and other conventional therapies. At 4 weeks after treatment, electrophysiological examination was performed. In addition, sensory and motor function of the distal end of injured nerve was evaluated at 6 months after treatment. RESULTS AND CONCLUSION: Sensory evoked potential and motor evoked potential showed that the recovery rate was 78% (n=14) and 83% (n=15) respectively in the case group, while 57% (n=10) and 66% (n=12) in the control group. There was significant difference between the two groups (P < 0.05). The total effective rate was 94.4% (n=17) in the case group and 83.3% (n=15) in the control group, which were statisticaly better in the case group than the control group (P < 0.05). These findings indicate that it is significantly effective to treat peripheral nerve injury by gelatin sponge infiltrated by mouse nerve growth factor that has good biocompatibility.

Chinese Journal of Tissue Engineering Research 2020;24(12):1817-1822
BACKGROUND: The morbidity rate of thoracolumbar burst fracture is high; however, the simple posterior distraction and reduction technique has poor patient satisfaction on maintaining vertebral height and reducing complications. Therefore, we attempt to explore a better therapeutic regimen. OBJECTIVE: To assess the efficacy of inverse arch roof breaking technique combined with pedicle screw and bone graft in treatment of thoracolumbar burst fractures. METHODS: This was a retrospective study of 78 patients with thoracolumbar burst fractures. All the patients suffered from fresh closed fractures, and all of them were operated by posterior approach. The time from injury to surgery ranged from 4 to 14 days, with an average of 7.8 days. They were randomly assigned to two groups. The 38 cases in the simple distraction group were treated with simple vertebra pedicle screw-rod system distraction and reduction fixation. The 40 cases in the inverse arch roof breaking and bone graft group were treated with inverse arch roof breaking technique combined with pedicle screw and bone graft in fractured vertebra. All patients signed the informed consent. The study was approved by the Hospital Ethics Committee. Operation time, intraoperative blood loss, fracture healing time, anterior height ratio of injured vertebrae, Cobb angle, visual analogue score, Barthel Index and postoperative complications were measured between the two groups. RESULTS AND CONCLUSION: (1) The follow-up period for all patients was 10-22 months. (2) Operation time and intraoperative blood loss were better in the simple distraction group than in the inverse arch roof breaking and bone graft group (P < 0.01). (3) The ratio of anterior height of injured vertebra and Cobb angle were significantly different between the two groups (P < 0.01). Above indexes were better in the inverse arch roof breaking and bone graft group than in the simple distraction group. (4) There were significant differences in fracture healing time and life activity function (Barthel index) between the two groups (P < 0.01), and above indexes were better in the inverse arch roof breaking and bone graft group than in the simple distraction group. (5) No deep infection was found in both groups. There were no complications such as internal fixation failure and excessive loss of vertebral height in arch roof breaking and bone graft group. In the simple distraction group, there were 3 cases of screw pull-out because of failed internal fixation, 2 cases of titanium rod breakage, and 10 cases of obvious vertebral height loss. (6) These findings suggest that compared with simple distraction and reduction fixation, inverse arch roof breaking technique combined with pedicle screw and bone graft can provide bony support to compression center of fractured vertebra. The efficacy was identified in reconstructing the height of anterior and middle columns. This method has the advantages of high mechanical strength, strong vertebral height maintenance, high bone healing rate and few complications, which will be the ideal choice in the treatment of thoracolumbar burst fracture.

BACKGROUND: Expectant treatment for intertrochanteric fractures in elderly patients with osteoporosis and other chronic diseases can easily lead to complications of lying in bed.OBJECTIVE: To evaluate the results of percutaneous compression plating system (PCCP) for intertrochanteric fractures in elderly patients. METHODS: Thirty-two cases of elderly intertrochanteric fractures treated with PCCP admitted from June 2007 to June 2009 and 40 cases of elderly intertrochanteric fractures treated with dynamic hip screw system (DHS) were reviewed. The operative bleeding, operative time and curative effect were compared.RESULTS AND CONCLUSION: The operative bleeding and operative time in the patients receiving PCCP were significantly lower than those in the patients receiving DHS. There was not statistical significance between the curative effects about the two methods. PCCP applied in elderly patients with intertrochanteric fracture can get satisfactory effects, and the system is operated simply with minimally invasive surgery, which is beneficial to reduce surgical complications.

Objective To investigate the correlation between three gene locus polymorphisms of X-ray repair cross-complementary protein 1 (XRCC1) exon (Arg194Trp, Arg280His and Arg399Gln) and the risk of colorectal cancer (CRC). Methods A case-control study was performed in 250 CRC patients (case group, 128 colon cancer patients and 122 rectal cancer patients) and 213 healthy individuals (control group). The three gene locus polymorphism of XRCC1 was tested by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method. The genotype distribution and allele frequency of each locus was analyzed with SPSS 10.0 software. Results There was no significant difference in allele frequency of XRCC1 at 194 and 399 loci (P > 0.05). However, the 280 Arg/His allele frequency of XRCC1 was higher in case group than that in control group (OR=1.66,95%CI:1.01~2.73,P=0.047). The 280Arg/His allele frequency was higher in rectal cancer group than that in control group (OR =1.82,95%CI:1.02~3.27). The frequency of 280His allele (Arg280His and His280His) was higher in case group than that in control group (OR=1.85,95%CI:1.06~3.22). However, it was a relative low risk factor of colon cancer and there was no significant difference between colon cancer group and control group (OR=1.85, 95%CI:1.06~3.22). Conclusions There was no correlation between XRCC1 Arg194Trp and Arg399Gln polymorpohisms and the risk of CRC. However, 280Arg/His genotype may increase the risk of CRC, and 280His allele is a risk factor of rectal cancer.
