Objective To investigate the efficacy of the enhancement treatment on osteoporotic vertebral compression fracture and its complications in the elderly.Methods From September 2007 to February 2012,183 patients with osteoporotic vertebral compression fracture underwent percutaneous kyphoplasty (PKP) or percutaneous vertebroplasty (PVP) in our department.157 of them were completely followed up (PKP group,n=96; PVP group,n=61) and totally 182 vertebral bodies were fractured (PKP group,n=107; PVP group,n=75).Visual analogue scale (VAS) score and Oswestry disability index (ODI) score were evaluated before and 3 days and 3 months after the surgery.Plain film radiography was taken to evaluate the vertebral body height.ODI score was evaluated at the end of the follow-up.The leakage of polymethylmethacrylate (PMMA) during the operation and the refracture were recorded.Results The mean height of the vertebral body before operation had no difference between PVP and PKP group [(1.31±0.18) cm vs.(1.32±0.16) cm,t =0.72,P＞0.05].After the operation,the mean height of the vertebral body was lower in PVP group than in PKP group [(1.50±0.20) cm vs.(1.66±0.17) cm,t=2.28,P＜0.05].The mean amount of the PMMA injected into the vertebral bodies was less in PVP group than in PKP group [(2.93±0.34) ml vs.(3.34±0.49) ml,t=2.39,P＜0.05].In the PVP group,the VAS scores were (7.5±0.79),(3.0±0.6) and (1.9±0.9) before,3 days and 3 months after operation respectively,and there was a significant difference in VAS score before versus 3 days after operation (t =15.59,P＜0.05).In thePKPgroup,the VAS scores were (7.3±1.0),(3.0±0.8) and (2.2± 0.9)before,3 days and 3 months after operation respectively,and there was a significant difference in VAS score before versus 3 days after operation (t=10.69,P＜0.05).In the PVP group,the ODI scores were (78.9±7.3),(30.0±3.7) and (25.5±3.5) before and 3 months after operation and at the end of follow-up respectively,and there were significant differences in ODI score before operation versus 3 months after operation (t=20.83,P＜0.01) and 3 months after operation versus at the end of follow-up (t=4.03,P＜0.05).In the PKP group,the ODI scores were (78.8±6.8),(29.8±4.43) and (23.8 ± 2.7) before operation,3 months after operation and at the end of follow-up respectively,and there were significant differences in ODI score before operation versus 3 months after operation (t=21.52,P＜0.01) and 3 months after operation versus at the end of follow-up (t=3.14,P＜0.05).There were no significant differences in VAS and ODI scores between the two groups before versus after operation (t=0.34,P＞0.05).The incidence of refracture was 8.2％ in PVP group and 9.4％ in PKP group,which had no statistical difference between the two groups(x2 =0.06,P＞0.05).All the leakage was asymptomatic.The incidence of PMMA leakage was 20.0％ (15 cases) in PVP group and 9.3％ (10 cases) in PKP group,which had a statistical difference between the two groups (x2 =4.22,P ＜ 0.05).Conclusions Enhancement treatment for osteoporotic vertebral compression fracture can quickly relieve the pain and improve the quality of life.PKP and PVP show no differences in the effect of analgesia and the improvement of life quality,but PKP has the advantages in recovering vertebral height and reducing PMMA leakage.

Objective:To investigate the relationship between levels of plasma thrombopoietin(TPO) and thrombocytopenia.Methods:Sixty-eight thrombocytopenia with different causes were injected with rhIL-11 domestically made, by 25 ?g/(kg?d) for 10 days continuously. The plasma TPO levels were determined by quantitative sandwich enzyme immunoassay technique in thrombocytopenic patients between before and after treatment.Results:(1)The serum TPO controls of patients with thrombocytopenia after acute leukemia(AL) chemotherapy were lower than normal controls. The plasma TPO levels in aplastic anemia(AA) and myelodysplastic syndrome(MDS) patients were all elevated compared to those in normal controls.The serum TPO levels in patients with idiopathic thrombocytopenic purpura(ITP) and liver cirrhosis had no difference with the normals. Bone marrow megakaryocytes(MK) count in after chemotherapy AL and AA patients were lower than those with normal serum TPO levels controls. (2)In all above patients used interleukin-11(rhIL-11), their TPO levels were close to normal in efficiency patients. On the contrary, their TPO did not change dramatic. Those react to rhIL-11, their TPO levels were inversely correlated with platelet count.Conclusion:Testing serum TPO levels would be helpful for distinguish the thrombocytopenia with different causes, and provides theorical support to patients to use rhIL-11 reasonably.

Objective To investigate the clinical effect of Zero-profile anterior cervical interbody fusion on single-segment cervical spondylosis in the elderly, and to compare with the effect of traditional anterior cervical decompression and fusion (ACDF) with titanium plate.Methods Clinical data of elderly patients who underwent anterior cervical discectomy and fusion operation (one-or two-level) in our department from June 2009 to March 2014 were retrospectively analyzed.The 49 patients who took anterior cervical interbody fusion with the Zero-profile cage were considered as the Zero-P group, and the other 60 patients who received ACDF with titanium plate as control (ACDFP group).The operation time, blood loss, Neck Disability Index (NDI) score before and after operation, Cobb angle of the cervical spine and Cobb angle of the operated segment before and after operation, the fusion rate 1 year after operation, the dysphagia rate after operation according to Bazaz index were recorded and assessed.Results The operation time and blood loss had no statistical difference between the two group (P＞0.05 for both).The NDI scores were declined in the two group after operation as compared with before treatment (P＜0.05 for both), while there were no statistical difference in NDI score between the two groups (P＞0.05).The Cobb angle of cervical spine had little improvement 1 day after operation as compared with before operation, and improved significantly 3 month after operation in the two group.The Cobb angle of operated segment (Cobb S) was reduced 3 months in the two group after operation as compared with before treatment, and the Cobb S was declined much more in Zero-P group than in control group (P＜0.01).There was no statistical difference in the number of patients with successful fusion between the two group (46 cases vs.56 cases, x2 =0.08, P＞ 0.05).Conclusions The clinical effect of Zero-profile anterior cervical interbody fusion is equivalent as the traditional ACDFP.Zero-profile anterior cervical interbody fusion has less exposure and blood loss, which is more suitable for the elderly patients with cervical degenerative disease.

A bacterium(designated as LW-3), capable of degrading Chlorimuron-ethyl, was isolated from the long-term contaminated soil by Chlorimuron-ethyl. Based on physiological and biochemical analyses and sequences comparison of 16S rDNA, strain LW-3 was identified as Pseudomonas sp. LW-3 could use Chlorimuron-ethyl as sole nitrogen source for growth. The optimum pH and temperature for degradation of Chlorimuron-ethyl were pH 6.5~7.2 and 30?C~35?C, at same temperature the pH change to the Chlorimuron -ethyl degrading influence is large. When the pH and temperature were pH 6.5 and 32?C, 50 mg/L Chlori- muron-ethyl could be degraded to 70%~80% level within 7 days.

Objective: Acute pancreatitis(AP) often impairs peripancreatic tissues and involves more distant organs,such as the liver,which would exacerbate the progression of the disease.This study aimed to explore the clinical characteristics of acute pancreatitis-associated liver injury.Methods: We randomly retrieved 156 cases of AP from the medical records retrieval system of Jinling Hospital,of which 102 were complicated by liver injury.The latter were divided into a severe AP(n=44) and a mild AP group(n=58) for comparative analysis of the severity of liver injury and time of recovery.Results: Liver injury occurred in 65.38% of the AP patients,and it was more serious,had a longer disease course and took more time to recover in the severe than in the mild AP group.Conclusion: The incidence and severity of acute pancreatitis-associated liver injury are positively correlated with the severity of acute pancreatitis.

Objective:To explore the feasibility and precautions of laparoscopic pyeloplasty for children with hydronephrosis combined with renal trauma.Methods:The clinical data of 6 cases with hydronephrosis and renal trauma admitted to the Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from August 2016 to August 2019, aged from 5 to 11 years old (average age 7 years old) were reviewed.These patients had suffered renal trauma for 1 to 4 days.All patients had the symptoms of pain in the affected kidney, and 4 patients had hematuria.The renal pelvis diameter of all patients was more than 25 mm.The patients underwent laparoscopic pyeloplasty and renal rupture repairment, with the ureteral stent, perirenal drainage tube and catheter placed inside the body during the operation.Results:All operations were completed successfully without any blood transfusion and open surgery.Intrao-perative time was from 2.5 to 3.5 hours.Two cases had renal parenchymal contusion in the front lower pole of kidneys and 4 cases in the lateral lower pole.Five cases had renal cortex and pelvis rupture, and 1 case had renal cortical fracture and subcapsular hematoncus.After the operation, the perinephric drainage tube was pulled out in 3 to 5 days, the catheter was pulled out in 7 to 10 days, and the ureteral stent was removed in 6 to 8 weeks.All children recovered well and hydronephrosis was ameliorated.The glomerular filtration rates and fractional renal function were all improved.Conclusions:One stage laparoscopic pyeloplasty is safe and effective for the treatment of hydronephrosis with renal trauma in children.Renal trauma in children usually occurs at the lower pole of the kidney.Early operation is needed if hydronephrosis is aggravated and symptoms are not relieved after the trauma.Intraoperative impairment of renal parenchymal rupture can be conducted.For intraoperative bleeding in grade 3 renal injury, renal parenchyma suturation and removal of necrotic renal tissue should be adopted to arrest bleeding.

Objective: To examine the Longitudinal influence of perceived discrimination on pro social behavior of left alone junior middle school students and to explore the longitudinal mediating role of teacher-student relationship and classmate relationship, so as to provide a reference for improving pro social behavior of left behind junior middle school students. Methods: The Perceived Discrimination Questionnaire, Teacher-Student Relationship Questionnaire, Classmate Relationship Questionnaire and Prosocial Behavior Questionnaire were used to conduct two follow up surveys on 930 left behind junior middle school students in Guizhou Province at two time points, in mid November 2021(T1) and mid May 2022(T2). Deviation corrected Bootstrap method was used to examine the mediating effect of T2 teacher-student relationship and T2 classmate relationship on the impact of T1 discrimination perception on T2 pro social behavior. Results: The perceptions of discrimination, teacher-student relationship, classmate relationship, and pro social behavior scores of the left behind junior high school students were (1.98±0.94) (4.13± 0.77 ) (3.54±0.91) (3.52±0.75) for T1, and (3.98±0.83)(3.42±0.86)(3.48±0.72) for teacher-student relationship, classmate relationships and pro social behavior scrores of T2. After controlling for gender, age and self assessment of family economic status, T1 perceived discrimination negatively predicted T2 pro social behavior ( β =-0.07); and T1 perceived discrimination indirectly influenced T2 pro social behavior through T2 teacher-student relationship, and mediated effect value was -0.02(95% CI = -0.02 to -0.01); and T1 perceived discrimination indirectly influenced T2 pro social behavior through T2 classmate relationship, mediated effect was -0.03(95% CI =-0.05 to -0.02)( P <0.05). Conclusions Perceived discrimination not only directly reduces pro social behavior of left behind junior middle school students, but also indirectly and negatively affects pro social behavior of left alone junior middle school students by reducing teacher-student relationship and classmate relationship.
