Objective To observe the clinical efficacy ofXiaozhikang Formula Granules for the treatment of nonalcoholic fatty liver disease.Methods Totally 90 patients with nonalcoholic fatty liver disease were randomly divided into control group and treatment group, 45 cases in each group. Patients in the control group were treated with conventional western treatment and oral metformin enteric-coated metformin hydrochloride, while patients in the treatment group were treated withXiaozhikang Formula Granules on the basis of conventional western treatment for 3 months. Blood lipid and insulin resistance in the two groups before and after treatment were observed, and the clinical efficacy between the two groups was compared.Results Clinical excellence (35.5%), total effective rate (84.5%) and TCM syndrome score (13.78 ± 3.6) after treatment of treatment group were better than those of control group (P<0.05). GPT, GOT, TG, and TC in both groups were lower after the treatment (P<0.05,P<0.01). There existed statistical significance in TC and TG between the two groups after treatment (P<0.05). There existed statistical significance in B ultrasound index between the two groups after treatment (P<0.05), and the treatment group was superior. FBG and HOMA-IR in both groups significantly decreased after treatment (P<0.05), and the FBG in the treatment group after treatment was better than control group (P<0.05).Conclusion The efficacy ofXiaozhikang Formula Granules in the treatment of nonalcoholic fatty liver disease is remarkable.

Objective To investigate the anti-fatigue effect of complex bear gall agent in mice.Methods Different dose of complex bear gall agent(4.4ml/kg、6.6ml/kg、13.2rml/kg)were given to mice by intragastric administration. The time of climbing-pole and loaded-swimming, hepatic glycogen content, serum urea nitrogen,lactic acid and lactate dehydrogenase of mice after swim were observed. Results The experiments indicated that complex bear gall agent could greatly increase the time of loaded-swimming and climbing Pole,increase the hepatic glycogen content and serum lactate dehydrogenase activity ,decrease serum urea nitrogen and blood lactic acid content in mice. Conclusion Complex bear gall agent had a significant anti-fatigue effect.

Objective To investigate the effect of minitype titanium plate fixation through transoral approach in the treatment of unstable atlas fractures.Methods A retrospective case series study was made on 21 patients with unstable atlas fractures treated by minitype titanium plate fixation through transoral approach from June 2008 to June 2014.There were 15 males and 6 females,at age of (40.9 ± 10.6)years (range,21 to 57 years).Anterior 1/2 Jefferson fractures were seen in 12 patients and 1/2 ring Jefferson fractures in 9 patients.Preoperative visual analogue score (VAS) was 4-9 points [(7.6 ± 1.3) points].Before operation,degree of mobility of the cervical vertebra was (15.4 ± 3.9) °in bending,(10.8 ± 2.5) °in extending,(18.3 ± 3.1) ° in left-bending,(18.9 ± 2.7) ° in right-bending,(21.8 ± 5.8) °in left-rotation and (22.4 ± 4.6) ° in right-rotation.Operation time,intraoperative blood loss,VAS,cervical mobility and bone healing were detected after operation.Results Operation time was (86.3 ±25.3)m in,and intraoperative blood loss was (120.5 ± 33.3)ml.VAS was improved to 0-2 points [(1.6 ± 0.4) points] at postoperative 3 days (P ＜ 0.05).All patients were followed up for 12 to 48 months[(23.7 ±5.9) months].VAS was improved to 0-2 points[(0.6 ± 0.1) points] at postoperative 3 months (P ＜ 0.05).Degree of mobility of the cervical vertebra was improved significantly at postoperative 3 months,with the bending of(38.6 ± 4.5) °,extending of (39.3 ± 4.0) °,left-bending of (39.2 ± 4.0) °,right-bending of (39.2 ± 2.9) °,left-rotation of (66.8 ± 8.8) ° and right-rotation of (66.3 ± 9.2) ° (P ＜ 0.05).Postoperatively,there were no surgical wound incision infections and vertebral artery or spinal injuries,Bone union was found in all patients,without the occurrence of implant loosening or breakage and the dysfunction of the cervical vertebra.Conclusion Minitype titanium plate fixation through transoral approach is associated with less trauma,high healing rate and preservation of the activity of cervical vertebra in the treatment of unstable atlas fractures.

ObjectiveThrough improving the potential of vascular endothelial growth factor receptor (VEGFR)-humanized mouse model (hKDR^+/+) with C57BL/6N background to allow the growth of different mouse tumor cell lines, to establish novel tumor-bearing mouse models which can support in vivo tumorigenesis of different mouse tumor cell lines and be used to evaluate drugs targeting VEGFR.MethodsFirstly, a method to evaluate the in vivo activity of antibody targeting VEGFR based on the hKDR^+/+ humanized mouse model was established. Recombinant activating gene 1 (Rag1) knockout mice (Rag1^-/-) were established using CRISPR/Cas9 technology. Then these Rag1^-/- mice were crossed with hKDR^+/+ mice to get a double gene modified homozygous hKDR^+/+/Rag1^-/- mouse model by screening. Finally, tumor cell lines derived from different mouse strains were tested on the double gene-modified mouse model to compare the differences in tumor growth. ResultsAntibodies designed for VEGFR showed significant anti-tumor activity in hKDR^+/+ mice, which significantly reduced tumor volume and weight compared with the PBS group (P<0.01, P<0.05). The number of B cells and T cells in the peripheral blood of Rag1^-/- mice and hKDR^+/+/Rag1^-/- mice decreased (P<0.05, P<0.001). Tumors were observed in hKDR^+/+/Rag1^-/-, Rag1^-/-, wild-type, and hKDR^+/+ mice after 7 d of inoculation of MC38 cells derived from C57BL/6 mice. Tumors were only observed in groups of hKDR^+/+/Rag1^-/- and Rag1^-/- mice, but not in the wild-type and hKDR^+/+ mice after 10 d of inoculation with CT26 cells derived from BALB/c mice. After 3 weeks of inoculation, the tumor volume of hKDR^+/+/Rag1^-/- mice was significantly larger than that of Rag1^-/- mice (P<0.01). ConclusionRag1 knockout mice were obtained and a novel hKDR^+/+/Rag1^-/- double genes modified mouse model was further screened. The tumor cell lines from different mouse strain origins were more prone to growth in mice with Rag1 gene deficiency. The results suggest that the reduced immune response of hKDR^+/+ humanized mice will improve the capacity of supporting the growth of mouse tumor lines in the model. As a result, more tumor-bearing mouse models may be constructed for the evaluation of drugs targeting VEGFR in this way.
