Objective:To explore the roles of the caudal ventrolateral medulla(CVLM) in the central anti-hypertensive mechanism. Methods : In 20 urethane-anesthetized SD rats, the effects of I1-imidazoline receptor and ?2-adrenceptor antagonists (microinjection into the CVLM) on the cardiovascular responses induced by intravenous clonidine were observed. Results: Prior bilateral microinjection of mixed antagonist idazoxan (I1-imidazoline receptor and a2-adrenceptor) into the CVLM not only decreased the mean arterial pressure [(-17. 3 ? 6. 9) mmHg, 1 mmHg = 0. 133 kPa, P

Objective To analyze the intratumoral and peritumoral microvessel density (MVD) and microlymphatic vessel density (MLVD) in pancreatic cancer and record the expression of vascular endothelial growth factor(VEGF)-C and VEGF-D. And to explore the significance of VEGF-C and VEGF-D during the lymphatic metastasis and development of pancreatic cancer. Methods The expression of VEGF-C and VEGF-D, VEGF-R3, CD34 were assayed by immunohistochemical staining in 30 cases of pancreatic cancer tissues. Results The positive rates of VEGF-C and VEGF-D protein in the central portion of tumors (30% and 16.7%) were significantly lower than those in the marginal portion (73.3% and 56.7%), P <0.01. The group with high expression of VEGF-C and VEGF-D in the marginal portion had significantly higher incidences of lymph node metastasis, lymphatic invasion and venous invasion( P <0. 01 ). MLVD in both of the VEGF-C and VEGF-D positive groups was higher than that in the negative groups( P <0. 01 ), and the lymph node me-tastasis increased. MVD in VEGF-C positive group was significantly higher than that in the negative group. MVD had no significant difference between VEGF-D positive and negative group ( P =0. 07). Conclusions The expression of VEGF-C and VEGF-D in the marginal portion of tumor is significantly correlated with lym-phatic metastasis in pancreatic cancer patients, and may induce lymphangiogenesis. VEGF-C may play an im-portant role in the regulation of angiogenesis and lymphangiogenesis in pancreatic cancer, and VEGF- D maybe only participate in the regulation of lymphangiogenesis.

Objective:To compare the effect of O-arm assisted and free-hand pedicle screw placement in the treatment of AO type C thoracolumbar fracture.Methods:A retrospective cohort study was used to analyze the clinical data of 34 patients with type C thoracolumbar fracture admitted to Henan Provincial People′s Hospital from January 2018 to June 2021, including 23 males and 11 females; aged 42-63 years [(50.4±7.4)years]. The fracture was located at T 11 in 4 patients, T 12 in 10, L 1 in 12, L 2 in 6, T 11~12/L 1 in 1 and T 12/L 1 in 1. Posterior reduction and internal fixation was carried out for all patients, of whom 18 were treated with O-arm assisted pedicle screw placement (navigation group) and 16 with free-hand pedicle screw placement (free-hand group). The operation time, single screw placement time, intraoperative bleeding volume, operation mode and screw placement accuracy were compared between the two groups. The kyphotic Cobb angle, visual analogue score (VAS) and American Spinal Injury Association (ASIA) score were compared between the two groups before operation, at 1 week after operation, at 3 months after operation and at the last follow-up. Postoperative complications were observed. Results:All patients were followed up for 12-29 months [(16.8±6.1)months]. There was no significant difference between the two groups in the operation time, intraoperative bleeding volume and operation mode (all P>0.05). The single screw placement time was (9.4±1.6)minutes in navigation group, but was (10.8±1.5)minutes in free-hand group ( P<0.05). The screw placement accuracy was 97.4% in navigation group, but was 81.5% in free-hand group ( P<0.01). The kyphotic Cobb angle and VAS had no significant differences between the two groups before operation (all P>0.05). The kyphotic Cobb angle in navigation group and free-hand group was (4.3±1.1)° and (5.9±1.1)° at 1 week after operation, (4.4±1.2)° and (5.7±1.3)° at 3 months after operation, and (4.4±1.2)° and (6.8±0.9)° at the last follow-up, decreased significantly from that before operation [(21.8±3.1)°, (22.2±3.2)°] (all P<0.01). The kyphotic Cobb angle in navigation group was significantly lower than that in free-hand group at 1 week, 3 months after operation and at the last follow-up (all P<0.01). The VAS in navigation group and free-hand group was (3.2±0.7)points and (4.1±0.7)points at 1 week after operation, (2.4±0.6)points and (3.0±0.8)points at 3 months after operation, and (1.8±0.9)points and (2.6±0.7)points at the last follow-up, decreased significantly from that before operation [(8.4±0.8)points, (8.3±0.9)points] (all P<0.01). The VAS in navigation group was significantly lower than that in free-hand group at 1 week, 3 months after operation and at the last follow-up (all P<0.01). The ASIA score showed no significant difference within and between the two groups before operation, at 1 week, 3 months after operation and at the last follow-up (all P>0.05). Postoperative incision infection occurred in 1 patient in both groups ( P>0.05). Implant failure such as loosening or displacement was not observed in navigation group, and only occurred in 2 patients in free-hand group ( P>0.05). Conclusion:Compared with free-hand pedicle screw placement, O-arm assisted pedicle screw placement in the treatment of AO type C thoracolumbar fracture has advantages of rapid and accurate screw placement, good reduction and notable pain relief.

Objective:To explore the clinical application value of personalized positioning using a cervical collar combined with a vacuum pad in the Cyberknife radiosurgery for cervical spine metastases.Methods:This study enrolled 68 patients with cervical spine metastases to be treated with Cyberknife stereotactic radiotherapy for cervical spines. These patients consisted of 41 males and 27 females, aged from 43 to 78 years (average: 51.5 years). They were divided into groups A, B, and C using the random number table method. The patient positioning in these groups was achieved using a cervical collar combined with a vacuum pad (personalized positioning), a vacuum pad, and a small head mold, respectively. After the first treatment, the comfort levels of the positioning molds during treatment were investigated. After radiotherapy, the average deviations in translational and rotational directions, the minimum tolerance distance (dxAB), the minimum rotational deviation angle (drAB), the proportion of false nodes, and the comfort level of the three positioning method were acquired for analysis.Results:The three groups showed statistically significant differences in the inf-sup, left-right, ant-post, pitch, roll, and yaw directions during the first treatment ( F = 7.13, 2.56, 3.41, 4.21, 2.71, 8.14, P < 0.05). Compared with groups B and C, Group A had significantly lower dxAB, drAB, and the proportion of false nodes, showing statistically significant differences ( F = 5.06, 4.31, 3.30, P < 0.05). Furthermore, patients in groups A and B felt more comfortable with the positioning molds than those in Group C ( χ2 = 12.46, P < 0.05), with no statistically significant differences between groups A and B ( P > 0.05). Conclusions:For patients with cervical spine metastases undergoing Cyberknife radiosurgery for cervical spines, the personalized positioning using a cervical collar combined with a vacuum pad can improve the accuracy and safety of Cyberknife spinal tracking while remaining the comfort level.

BACKGROUND:Osteoporotic fracture is the most serious complication of osteoporosis.Previous studies have demonstrated that gut microbiota has a regulatory effect on skeletal tissue and that gut microbiota has an important relationship with osteoporotic fracture,but the causal relationship between the two is unclear. OBJECTIVE:To explore the causal relationship between gut microbiota and osteoporotic fractures using Mendelian randomization method. METHODS:The genome-wide association study(GWAS)datasets of gut microbiota and osteoporotic fracture were obtained from the IEU Open GWAS database and the Finnish database R9,respectively.Using gut microbiota as the exposure factor and osteoporotic fracture as the outcome variable,Mendelian randomization analyses with random-effects inverse variance weighted,MR-Egger regression,weighted median,simple model,and weighted model methods were performed to assess whether there is a causal relationship between gut microbiota and osteoporotic fracture.Sensitivity analyses were performed to test the reliability and robustness of the results.Reverse Mendelian randomization analyses were performed to further validate the causal relationship identified in the forward Mendelian randomization analyses. RESULTS AND CONCLUSION:The results of this Mendelian randomization analysis indicated a causal relationship between gut microbiota and osteoporotic fracture.Elevated abundance of Actinomycetales[odds ratio(OR)=1.562,95%confidence interval(CI):1.027-2.375,P=0.037),Actinomycetaceae(OR=1.561,95%CI:1.027-2.374,P=0.037),Actinomyces(OR=1.544,95%CI:1.130-2.110,P=0.006),Butyricicoccus(OR=1.781,95%CI:1.194-2.657,P=0.005),Coprococcus 2(OR=1.550,95%CI:1.068-2.251,P=0.021),Family ⅩⅢ UCG-001(OR=1.473,95%CI:1.001-2.168,P=0.049),Methanobrevibacter(OR=1.274,95%CI:1.001-1.621,P=0.049),and Roseburia(OR=1.429,95%CI:1.015-2.013,P=0.041)would increase the risk of osteoporotic fractures in patients.Elevated abundance of Bacteroidia(OR=0.660,95%CI:0.455-0.959,P=0.029),Bacteroidales(OR=0.660,95%CI:0.455-0.959,P=0.029),Christensenellacea(OR=0.725,95%CI:0.529-0.995,P=0.047),Ruminococcaceae(OR=0.643,95%CI:0.443-0.933,P=0.020),Enterorhabdus(OR=0.558,95%CI:0.395-0.788,P=0.001),Eubacterium rectale group(OR=0.631,95%CI:0.435-0.916,P=0.016),Lachnospiraceae UCG008(OR=0.738,95%CI:0.546-0.998,P=0.048),and Ruminiclostridium 9(OR=0.492,95%CI:0.324-0.746,P=0.001)would reduce the risk of osteoporotic fractures in patients.We identified 16 gut microbiota associated with osteoporotic fracture by the Mendelian randomization method.That is,using gut microbiota as the exposure factor and osteoporotic fracture as the outcome variable,eight gut microbiota showed positive causal associations with osteoporotic fracture and another eight gut microbiota showed negative causal associations with osteoporotic fracture.The results of this study not only identify new biomarkers for the early prediction of osteoporotic fracture and potential therapeutic targets in clinical practice,but also provide an experimental basis and theoretical basis for the study of improving the occurrence and prognosis of osteoporotic fracture through gut microbiota in bone tissue engineering.
