AIM: To investigate whether grafting neural stem cells (NSCs) improves the impaired cognitive deficits and spatial recognition after ischemic-hypoxic brain damage (HIBD) in neonatal rats. METHODS: Non-immunosuppressed 7-day-old SD rats were used as research subject and randomly divided into 3 groups: (1) sham group (n=10); (2) HIBD group (n=11); (3) transplant group (n=13). (2) and (3) were anesthetized and subjected to a hypoxic/ischemic injury obtained by combination of left carotid ligation and exposure to 8% oxygen for 2 h. At 3 days post injury, hypoxic-ischemic brain damaged animals were re-anesthetized and randomized to receive stereotactic injection of NSCs prelabeling with BrdU or control media into the hippocampus in the ipsilateral hemisphere. Cognitive (i.e., learning) deficits were assessed at 2 to 4 weeks after transplantation. At the end of the behavioral tests, the animals were killed and evaluated for NSC survival and histopathological analysis. RESULTS: Transplant group showed significantly improved cognitive function in selected tests as compared with HIBD group during the 4-week observation period. They took less time than HIBD group in finding the 3 arms baited with water and had a decreased number of working and reference memory errors in radial maze acquisition tests. Histological analysis showed that transplanted NSCs attenuated CA1 cell loss after HIBD, and NSCs survived for as long as 4 weeks after transplantation and were detected in the hippocampus. CONCLUSION: These data suggest that transplanted NSCs attenuate brain damage and cognitive dysfunction after hypoxic-ischemic brain damage. This approach warrants continued investigation in light of potential therapeutic uses.

Objective To investigate the protective effect of Qingkailing (QKL) in cardiac muscle's injury induced by endotoxin and discuss the mechanism from the inflammatory factors expression and free radical metabolism. Methods A total of 48 male ICR mice were divided into normal group, model group, low dose group and high dose group, 12 mice in each group. The QKL(9 ml/kg) was administered via gavage daily for 4 days in low dose group, the QKL (18 ml/kg) was administered via gavage daily for 4 days in high dose group, the equivalent volume of saline was administered via gavage daily for 4 days in normal group and model group. At the fifth day all groups except normal group, received intraperitoneal injection of LPS 0.2 ml (40 mg/kg), and the normal group received equivalent volume of saline. Intragastric administrated again 0.5h, 8h and 20 h after the model establishment. We took blood from hearts 1 hour after the last administration. The QR-PCR was used to detect the expression of inflammatory factors. The Elisa was used to detect IL-1β, IL-6, TNF-α, MDA, SOD and GSH-Px. Results Compared to the model group, the content of TNF-α (68.75 ± 7.73 pg/ml, 62.03 ± 16.09 pg/ml vs. 116.06 ± 21.06 pg/ml), IL-1β (110.84 ± 40.61 pg/ml, 105.51 ± 38.21 pg/ml vs. 167.53 ± 54.82 pg/ml) and IL-6 (68.78 ± 20.57 pg/ml, 59.71 ± 13.59 pg/ml vs. 108.80 ± 28.21 pg/ml) in low dose group and high dose group were significantly decreased (P<0.01). The expression of TNFα mRNA (1.42 ± 0.15, 1.30 ± 0.46 vs. 3.00 ± 0.82),IL-1β mRNA (1.20 ± 0.57, 1.01 ± 0.40 vs. 2.32 ± 1.39) and IL-6 mRNA (1.53 ± 1.10, 1.16 ± 1.09 vs. 4.12 ± 2.23) in low dose group and high dose group were significantly decreased (P<0.01 or P<0.05). The content of MDA (10.64 ± 2.91 nmol/mg, 11.36 ± 3.02 nmol/mg vs. 15.21 ± 2.31 nmol/mg) in low dose group and high dose group were significantly decreased (P<0.01). The content of SOD (282.32 ± 35.90 U/mg, 325.07 ± 34.76 U/mg vs. 249.01 ± 45.22 U/mg) and GSH-Px (48.26 ± 17.13 U/g, 49.66 ± 22.11 U/g vs. 26.47 ± 20.37 U/g) in low dose group and high dose group were significantly increased (P<0.01). Conclusions The QKL plays a protective role in myocardial injury induced by endotoxemia. Its mechanism may be associated with down-regulation of expression of inflammatory factors, reducing free radicals and improvement of antioxidation.
7. Percutaneous screw fixation versus traditional plate fixation for treating pubic branch fracture
Chinese Journal of Tissue Engineering Research 2020;24(18):2861-2866
BACKGROUND: Fracture of the pubic branch is a common type of anterior pelvic ring injury. Fixation of the pubic branch fracture can reduce the stress level of the posterior pelvic ring fixation system and reduce the separation of the pubic symphysis, which is beneficial to the stability of the pelvic ring. Both percutaneous screw fixation and traditional open reduction and internal fixation can be used to fix pubic branch fractures, but which method is better has not been confirmed. OBJECTIVE: To compare the efficacy of percutaneous screw fixation with conventional open reduction and plate fixation for pubic branch fracture. METHODS: Sixty-five patients of pubic branch fracture undergoing the surgical treatment at the Second Hospital of Anhui Medical University between January 2014 and December 2018 were included. The patients were randomly divided into percutaneous screw fixation group (n=33) and open reduction and plate fixation group (n=32). The patients signed the informed consents and the study was approved by the ethics committee of the hospital. The number of cases, sex, age, fracture classification, and American Society of Anesthesiologists score had no significant difference between two groups. The operation time, total blood loss, postoperative transfusion cases, incision length, postoperative discharge time and complications in both groups were recorded. Postoperative Matta score, Visual Analogue Scale score before and after surgery, and Majeed score during follow-up were recorded. RESULTS AND CONCLUSION: (1) Thirty patients in both groups were followed up, which was 8-59 months in the percutaneous screw fixation group, and 8-57 months in the open reduction and plate fixation group. (2) The percutaneous screw fixation group had smaller incision, lower incision infection rate, less bleeding, and shorter postoperative hospitalization time (P < 0.05). (3) Postoperative Visual Analogue Scale scores in both groups were decreased compared with the baseline levels (P < 0.05). The scores at postoperative 3 days in the percutaneous screw fixation group were significantly lower than those in the open reduction and plate fixation group (P < 0.05). The scores at postoperative 6 months were insignificant difference between two groups (P > 0.05). (4) The excellent and good rate of Matta score in the percutaneous screw fixation group was less than that in the open reduction and plate fixation group, and the difference was insignificant (P > 0.05). (5) There was no significant difference in the Majeed score at postoperative 6 months between two groups (P > 0.05). (6) Our results indicate that percutaneous screw fixation can achieve the same good effect as traditional plate fixation, and has the advantages of less trauma and faster postoperative recovery compared with traditional plate fixation.

Objective To investigate the protective effects of hyperbaric oxygen(HBO)against brain dam- age from hypoxic ischemia(HIBD)in neonatal rats.Methods One hundred and seventeen 7-day-old Sprague- Dawley rats were randomly divided into 4 groups:a control group(n=32),a hypoxic ischemia brain damage group (HIBD group,n=30),a hyperbaric air group(HBA group,n=27),and a hyperbaric oxygen group(HBO group, n=28).The HIBD model was established by permanent occlusion of the left common carotid artery followed by expo- sure to a mixture of 8% oxygen/92% nitrogen for 2 h(at 37℃).HBO therapy was administered to the HBO group after the hypoxia exposure once a day for 7 d,as was HBA therapy to the HBA group.Apoptotic cells in the cortex and hippocampus(A_(CH)cells)were measured using TUNEL at 9 d after birth,and the ratios of left and right cerebral hemisphere weight(R_(L/R))and rate of weight gain(GRW)were recorded 14 d after birth.A radial arm maze acquisi- tion test(RAMAT)was administered at 30 to 35 days.Lastly,the neuron density in the CA_1 subfield of the rats' hip- pocampi(ND_(CAI)was measured with Nissl staining.Results R_(L/R)and GRW in the HIBD group were significantly lower than in the control group(P<0.01),while R_(L/R)was increased in the HBO and HBA groups,especially in the HBO group(P<0.01),although there was no significant difference in GRW between the groups.Compared with the control group,A_(CH)cells were increased and ND_(CAI)was decreased in the HIBD group(P<0.01),while A_(CH)cells were decreased and ND_(CAI)was elevated in the HBO group in comparison with the HIBD group(P<0.01).There was no change in A_(CH)cells or ND_(CAI)in the HBA group.The RAMAT results for the HIBD group,including the time to find the arms baited with water,average times of working errors and reference memory errors,were significantly high- er than those of the control group,while these values for the HBO group were obviously lower than for the HIBD group,and there was no change for the HBA group(P>0.05).Conclusion HBO therapy might increase the re- covery of learning and memory function by attenuating HIBD in neonatal rats.
9. Rapid quality evaluation of Chuanxiong Rhizoma with multi-indicators by near infrared spectroscopy
Chinese Traditional and Herbal Drugs 2016;47(6):1004-1009
Objective: Near infrared spectroscopy (NIRS) method was used for rapid quality evaluation of Chuanxiong Rhizoma. Quantitative models of ferulic acid content, moisture content, and extractum content were established to improve the quality control of Chuanxiong Rhizoma. Methods: The contents of ferulic acid, moisture, and extractum were determined by high performance liquid chromatography, vacuum drying, and hot dipping methods, respectively. Partial least squares regression (PLSR) models were developed for the quantitative analysis on the contents of ferulic acid, moisture, and extractum. The contents of validation samples were predicted by established NIRS models. Results: The correlation coefficients (r) of the three models were 0.9130, 0.9059 and 0.9544, respectively. The root mean square errors of prediction (RMSEP) were 0.0003, 0.3056, and 2.2090, respectively. The relative standard errors (RSEP) were less than 10%, indicating satisfactory predicted results. Conclusion: The results demonstrate that NIRS method could be applied for the rapid determination to the contents of ferulic acid, moisture and extractum in Chuanxiong Rhizoma.
