ABSTRACT

Objective:To investigate the risk factors for axial deviation in the treatment of tibial defect susing Orthofix unilateral external fixator and proximal tibial osteotomy for bone transport.Methods:A retrospective study was performed to analyze the clinical data of 90 patients who had been treated for tibial bone defects by the Orthofix unilateral external fixator at Department of Microrepair and Reconstruction, The First Hospital Affiliated to Xinjiang Medical University from May 2012 to June 2019. There were 77 males and 13 females with a mean age of 41.2 years (from 17 to 63 years).The bone defects ranged from 4 to 13 cm in length. According to the Paley criteria for axial deviation, the 90 patients were divided into 2 groups: a deviation-free group with no axial deviation or an axial deviation ≤5° and a deviation group with an axial deviation>5°. The 2 groups were compared in terms of age, number of prior surgery, defect length, placement angle of Schanz screws, external fixation time, external fixation index and bending degree of Schanz screws at the last follow-up.The factors with P<0.05 were analyzed by multivariate logistic regression to find the risk factors for coronal axial deviation. Results:The 90 patients were followed up for an average of 23 months (from 12 to 40 months). The incidence of axial deviation in this cohort was 36.7% (33/90).The deviation group had a significantly larger number of prior surgery [5 (3, 6) times], a significantly longer defect length [8 (8, 9) cm], a significantly longer external fixation time [400.0 (341.8, 426.3) d], and a significantly greater bending degree of Schanz screws at the last follow-up [1.2° (0.4°, 3.5°)] than the deviation-free group [3 (2, 3) times, 6 (5, 8) cm, 340.8 (226.5, 422.8) d, and 0.8° (0.2°, 3.7°)] (all P<0.05). Multivariate logistic regression analysis showed that the number of prior surgery ( OR=2.581, 95% CI: 1.496-4.450, P=0.001) and the defect length ( OR=5.310, 95% CI: 1.952-14.442, P=0.001) were the risk factors for the axial deviation. Conclusion:In the treatment of tibial defect susing Orthofix unilateral external fixator and proximal tibial osteotomy for bone transport, the more prior surgeries and the longer a bone defect, the higher the risk for axial deviation.

ABSTRACT

Objective:To investigate the therapeutic effect of rat bone marrow mesenchymal stem cells (BMSCs) transfected with recombinant rat platelet-derived growth factor BB (rrPDGF-BB) gene on the distraction osteogenesis.Methods:From October, 2019 to June, 2020, 48 batches of BMSCs were cultured from 48 young SD rats, 24 of which were transfected with rrPDGF-BB gene by lentivirus. Meanwhile, other 72 male adult SD rats were randomly selected to establish the right femoral distraction osteogenesis model. The rats were equally divided into 3 groups. PBS, BMSCs without intervention and BMSCs transfected with rrPDGF-BB gene were injected into the distraction space of each group of rats assigned as Blank group, Negative group and Experimental group, respectively. Results of the experiment were evaluated by means of imaging and immunohistochemistry. P<0.05 indicated a statistically significant difference. Results:The cultured BMSCs grew well. The expression of CD34(0.1%) and CD45(2.8%) in the third generation of BMSCs was low, and that of CD29 (95.1%) was high, which was consistent with the phenotype of BMSCs described in literatures. After transfection, the expression of green fluorescence gradually increased with the extension of transfection time, confirming the success of transfection. After 14 days, all rats reached the expected distance of distraction. The rats were observed at assigned time points in 2, 4 and 8 weeks. The photos of femur specimen showed that continuous callus could be seen in the experimental group, the hardness and colour were close to the normal bone tissue, and the activity of the distraction space was poor, which was lower than that of the blank group. X-ray examination showed that there were more new callus in the experimental group, and the bone marrow cavity was re-canalized earlier than that of the blank group; Micro-CT examination, in sagittal plane, showed that the distraction space of the experimental group healed well, the broken end was connected, and the recanalization of bone marrow cavity was earlier than that of the blank group; Micro-CT parameters of each group showed that trabecular thickness[(0.297±0.005) mm], trabecular number [(1.663±0.032) mm], bone volume fraction[(59.832±2.187)%] and bone mineral density[(0.586±0.014) g/cm 3] of the experimental group were the greatest, while trabecular separation[(0.399±0.051) mm] of the experimental group was the smallest. There was statistical difference between each group( P < 0.05); HE staining and VEGF immunohistochemistry showed that the vessels and chondrocytes formed earlier and were more in the experimental group than that in the blank group. In 8 weeks, the new callus joined into one piece under the microscope in the experimental group, and the bone marrow cavity was re-canalized with a large number of red blood cells. Conclusion:Studies have shown that BMSCs transfected with rrPDGF-BB gene can promote the formation of callus in the distraction area of rats, shorten the mineralisation time of new callus, and promote the maturation of new bone in the area of distraction osteogenesis.

ABSTRACT

Objective To evaluate the role of TET3-induced DNA demethylation in methane-in-duced up-regulation of nuclear factor-erythroid 2-related factor 2 ( Nrf2) expression in rat spinal cord neu-rons subjected to oxygen-glucose deprivation and restoration ( OGD∕R) injury. Methods The primarily cultured spinal cord neurons of rats were seeded in 6-well plates at a density of 1×105 cells∕ml and divided into 5 groups ( n=48 each) using a random number table method: control group ( group C) , group OGD∕R, methane group (group M), methane plus TET3-siRNA group (group M+siTET3) and methane plus negative siRNA group (group M+siCon). The medium was replaced with glucose- and serum-free Earle's salt solution, and the neurons were exposed to 5% CO2-95%N2 in an incubator for 2 h followed by routine culture to establish the model of OGD∕R. In group M, 200μl methane-saturated saline ( final concentration of methane 1. 8 mmol∕L) was added at oxygen-glucose restoration. TET3-siRNA 100 pmol∕L and negative siRNA 100 pmol∕L were added at 24 h before oxygen-glucose restoration to perform transfection in M+siTET3 and M+siCon groups, respectively. At 12 h of oxygen-glucose restoration, the neuronal survival rate, release rate of lactic dehydrogenase ( LDH) and apoptotic rate of neurons were measured, and the ex-pression of TET3 and Nrf2 protein and mRNA was detected by Western blot and fluorescent quantitative re-al-time polymerase chain reaction, respectively, and contents of superoxide dismutase (SOD), catalase ( CAT) and malonaldehyde ( MDA) were measured by enzyme-linked immunosorbent assay. Neuronal DNA was extracted for determination of methylation and hydroxymethylation rates of DNA ( by enzyme-linked im-munosorbent assay) and methylation of CpG island in Nrf2 gene promoter ( by fluorescent real-time methyla-tion specific polymerase chain reaction). Results Compared with group C, the survival rate of neurons was significantly decreased, the release rate of LDH and apoptotic rate were increased in group OGD∕R ( P<0. 01) . Compared with OGD∕R, the survival rate of neurons was significantly increased, the release rate of LDH and apoptotic rate were decreased, the expression of TET3 and Nrf2 protein and mRNA was up-regula-ted, DNA hydroxymethylation rate and contents of SOD and CAT were increased, and the DNA and Nrf2 promoter methylation rates and MDA content were decreased in group M ( P<0. 05 or 0. 01) . Compared with group M, the neuronal survival rate was significantly decreased, the release rate of LDH and apoptotic rate were increased, the expression of TET3 and Nrf2 protein and mRNA was down-regulated, the DNA hydroxymethylation rate and contents of SOD and CAT were decreased, and the DNA and Nrf2 promoter methylation rates and MDA content were increased in group M+siTET3 ( P<0. 05 or 0. 01) , and no signifi-cant change was found in the parameters mentioned above in group M+siCon ( P>0. 05) . Conclusion The mechanism by which methane up-regulates Nrf2 expression in rat spinal cord neurons subjected to OGD∕R injury is related to activating TET3 and promoting DNA demethylation in Nrf2 promoter.

ABSTRACT

Objective@#To investigate the incidence of hepatic encephalopathy (HE) in patients with non-cirrhotic portal hypertension (NCPH) and to explore its risk factors.@*Methods@#The incidence rate of HE in 150 cases with NCPH was evaluated in two hospitals, and 188 cases of compensated cirrhosis patients were taken as control. Logistic regression was used to screen for independent risk factors for HE in patients with NCPH.@*Results@#The incidence of overt hepatic encephalopathy (OHE) in patients with NCPH was not statistically significantly different from that in patients with cirrhosis (4.7% vs. 6.9%, P = 0.682). The incidence of mild hepatic encephalopathy (MHE) was significantly lower than that of cirrhosis patients (32.7% vs. 46.3%, P < 0.05). The presence of upper gastrointestinal bleeding, infection and portosystemic venous shunt were the main independent factors for HE in NCPH patients (OR > 1, P < 0.05).@*Conclusion@#HE is one of the important complications of NCP, and may be influenced by factors such as upper gastrointestinal bleeding, infection and portosystemic venous shunt.

Methods From August 2012 to September 2016,112 patients with SAP in Yuncheng Central Hospital were selected and divided into three groups by random number table method. There were complete parenteral nutrition group(TPN group,n =37),early enteral nutrition group(EEN group,n = 37),parenteral and early enteral nutrition group(PN + EEN group, n = 38). The levels of CRP,LPS and tumor necrosis factor - α(TNF - α) in three groups were detected at the first day after admission,the seventh day and the fourteenth day after nutrition support respectively. The levels of D - lactic acid and diamine oxidase (DAO) in the three groups were detected at the first day after admission and the fourteenth day after nutrition support respectively. The occurrence of infection,abdominal distension,diarrhea,multiple organ failure syndrome (MODS),gastrointestinal bleeding among the three groups were compared at the fourteenth day after nutrition support. Results The levels of serum CRP,LPS and TNF - α at the seventh day and fourteenth day after nutrition support in the PN + EEN group[7d:(35. 56 ± 4. 54)mg/ L,(1. 59 ± 0. 58)EU/ L,(48. 56 ± 5. 25) ng/ L; 14d:(8. 68 ± 2. 36) mg/ L,(1. 23 ± 0. 43) EU/ L,(38. 63 ± 4. 82) ng/ L] were significantly lower than those in the TPN group[7d:(60. 86 ± 5. 63)mg/ L,(1. 91 ± 0. 59) EU/ L,(54. 10 ± 4. 02) ng/ L;14d: (28. 38 ± 2. 47) mg/ L, (1. 62 ± 0. 52)EU/ L,(44. 51 ± 4. 58)ng/ L]and the EEN group[7d:(59. 58 ± 5. 25)mg/ L,(1. 89 ± 0. 61)EU/ L, (52. 54 ± 5. 13) ng/ L;14d:(27. 45 ± 2. 13) mg/ L,(1. 58 ± 0. 46) EU/ L,(43. 21 ± 5. 20) ng/ L],the differences were statistically significant (tTPN group = 21. 451,35. 321,2. 369,3. 544,5. 121,5. 413,tEEN group = 21. 212,36. 127, 2. 183,3. 405,3. 320,3. 957,all P < 0. 05). The levels of D - lactic acid and DAO at the fourteenth day after nutrition support in the PN + EEN group[(5. 27 ± 1. 01)mg/ L,(5. 78 ± 1. 94)U/ L]were lower than those in the TPN group [(8. 62 ± 1. 26) mg/ L,(9. 32 ± 2. 04) U/ L] and the EEN group[(8. 43 ± 1. 08) mg/ L,(8. 98 ± 2. 01) U/ L] (tTPN group = 12. 619,12. 999,tEEN group = 7. 649,6. 968,all P < 0. 05). After nutritional support treatment for 14 days, the numbers of abdominal distension and diarrhea,MODS,infection in the PN + EEN group were 4 cases,2 cases and 5 cases,respectively,which were significantly lower than those in the EEN group(11 cases,8 cases,12 cases) and the TPN group(12 cases,9 cases,13 cases),the differences were statistically significant (χ2 = 5. 361,4. 321,4. 964, 3. 973,5. 442,4. 341,all P < 0. 05). Conclusion PN combined with EEN can effectively reduce the levels of CRP, LPS,TNF - α,D - lactic acid and DAO in patients with SAP,and improve the intestinal mucosal barrier function,it has fewer complications,the effect of clinical treatment is better,which is worthy of clinical promotion and application.

ABSTRACT

Anthrax is a zoonosis caused by Bacillus anthracis, which seriously affects human health. In recent years, a special phenomenon is found that the metabolic active of a bacterium remains after it is killed. To development of a KBMA (killed but metabolically active) Bacillus anthracis vaccine candidate strain, a plasmid pMAD and a recombinase system Cre-loxP were used to knockout the uvrAB gene of B. anthracis AP422 which lacks both of two plasmids pXO1 and pXO2. The results of PCR and RT-PCR shows that uvrAB genes were deleted from B. anthracis AP422 chromosome successfully. The constructed B. anthracis AP422deltauvrAB was inactivated by photochemical treatment (PCT) including an exposure in a long-wave-length ultraviolet (UVA) light and a treatment of 8-Methoxypsoralen (8-MOP), then the metabolic activity were detected by the method of MTS. The results showed that the killed B. anthracis AP422deltauvrAB maintained a highly metabolic activity for at least 4 hours, showing a state of KBMA. The KBMA strain of B. anthracis AP422deltauvrAB provides the prospective vaccine candidate strain for anthrax.

ABSTRACT

To investigate the effect of preceding naloxone injection into the third cerebroventricle or acute subdiaphragmatic vagotomy on the gastric acid secretion inhibited by the somatostatin analogue octreotide given by intracerebroventricular (icv) injection. The third ventricles were cannulated in male Wistar rats anesthetized with sodium pentobarbital. One week later, acute gastric lumen perfusion was carried out. The gastric perfusion samples were collected every 10 min and were fitrated by 0.01 mol/L NaOH to neuter. On the basis of subcutaneous injection of pentagastrin (G-5, 160 μ g/kg), icv injection of physiological saline (group A, n=20), icv injection of octreotide (0.05 μ g)(group B, n=20), icv injection of naloxone (2.5 μ g)+octreotide (0.05 μ g) (group C, n=20), acute subdiaphragmatic vagotomy+ icv injection of physiological saline (group D, n=20), or acute subdiaphragmatic vagotomy+icv injection of octreotide (0.05 μ g) (group E, n=20) were conducted. Before and after icy injection, 1-h total acid output (TAO) was determined and compared. The experimental data were expressed in change rate (%) of TAO. The change rates (%) of TAO were 4.60 % in group A, -20.35 % in group B, -18.06 % in group C, 5.01% in group D and -21.59 % in group E, respectively. Comparison of group B or C versus group A showed that P<0.01 and comparison between the group E versus group D showed that P<0.01. Whereas the differences between group C and group B, group E and group B were not statistically significant (P>0.05 for all). The results indicate that the central inhibition of gastric acid secretion by octreotide may not be mediated by the endogenous opiate substance or its receptor and the peripheral pathway for icv injection of octreotide to suppress gastric acid secretion is via extra-vagus route.

ABSTRACT

To investigate the effect of preceding naloxone injection into the third cerebroventricle or acute subdiaphragmatic vagotomy on the gastric acid secretion inhibited by the somatostatin analogue octreotide given by intracerebroventricular (icv) injection. The third ventricles were cannulated in male Wistar rats anesthetized with sodium pentobarbital. One week later, acute gastric lumen perfusion was carried out. The gastric perfusion samples were collected every 10 min and were titrated by 0.01 mol/L NaOH to neuter. On the basis of subcutaneous injection of pentagastrin (G-5, 160 micro, g/kg), icv injection of physiological saline (group A, n = 20), icv injection of octreotide (0.05 micro g) (group B, n = 20), icv injection of naloxone (2.5 micro g)+octreotide (0.05 micro g) (group C, n = 20), acute subdiaphragmatic vagotomy+ icv injection of physiological saline (group D, n = 20), or acute subdiaphragmatic vagotomy+icv injection of octreotide (0.05 micro g) (group E, n = 20) were conducted. Before and after icv injection, 1-h total acid output (TAO) was determined and compared. The experimental data were expressed in change rate (%) of TAO. The change rates (%) of TAO were 4.60% in group A, -20.35% in group B, -18.06% in group C, 5.01% in group D and -21.59% in group E, respectively. Comparison of group B or C versus group A showed that P 0.05 for all). The results indicate that the central inhibition of gastric acid secretion by octreotide may not be mediated by the endogenous opiate substance or its receptor and the peripheral pathway for icv injection of octreotide to suppress gastric acid secretion is via extra-vagus route.

ABSTRACT

The significance of the blood glutathion reductase activity coeff i-.cient (BGR-AC) as the guide line to assess riboflavin status in 28 radar operators was studied by comparing with the amount of their urinary excreted riboflavin.The 28 subjects were randomized into 4 groups and the riboflavin intake was 0.53.mg,1.0 mg,2.0 mg,and 3.0 mg respectively.It was found that there was a significant negative correlation between BGR-AC and urinary excretion of riboflavin,and with the incrase of riboflavin intake,there was a significant decrease of BGR-AC in Groups Ⅰ,Ⅱ,and Ⅲ though the difference between Group Ⅲ and Group Ⅳ was insigificant.On the basis of the BGR-AC values of the 4 groups,an exponential equation was established which tells the riboflavin requirement of radar operators.It is defined that when BGR-AC is smaller than equal to 1.24,it is normal and when it is larger than 1.24,it means abnormal riboflavin status of the individual.

ABSTRACT

The experimental rats were fed with 5 test diets of different protein quality.RNA content and 3-methylhistidhie(3-MH) in urine were determined.The results showed that the RNA content of the skeletl muscle cells was significantly different in rais fed with different diet.A linear correlation between RNA content and amino acid score of food protein was perceived.Food with the higher protein quality,the more 3-MH in urine was excreted.A good correlation between excrstiou of 3-MH and Net Portein Utilization(NPU),an index reflecting protein quality,existed too.These suggested that protein quality regulates the balance between auabolism and catabolism,meaning the turnover of skeletal muscle proteinThe mechanism of strengthening anabolism,not reducing catabolism,can explain that high protein quality could improve growth of animals.
