Objective To assess the importance of initial resuscitation, prevention and management of the early complication in acute cervical spine injury. Methods Initial resuscitation of 715 early complications of 10 types and their prevention and management in 194 cases with acute cervical spinal cord injury admitted from 1996 to 1998 were reviewed. Results Mortality in early stage could be markedly reduced with routine and normal initial resuscitation, pulmonary complications were the main cause of death. Early complications delayed the possible surgical treatment, affected the treatment results, increased the cost and duration of hospitalization and difficulty of rehabilitation. Conclusions Early complications of cervical spine injury mostly occur in the first few days and can be predicted. Proper prevention and treatment of it will benefit the recovery of the neural lesion and following rehabilitation.

Objective To study the mechanism and prevention for complications associated with postoperative T-Tube cholangiography.Method The study reviewed the data of six patients with complications following postoperative T-Tube cholangiography.Results Minor adverse reactions occurred in 4 cases, severe in 2.The severe reactions were related to cholangiovenous reflux resulted from the increase in intrabiliary pressure during postoperative T-Tube cholangiography.Conclusion Limitation of high intrabiliary pressure during the perfor mance of postoperative T-Tube cholangiography is the most important measure to prevent such reactions.

[Objective]To discuss the initiating and developing mechanism of OPLL,and the influence of different operations on happening and developing of OPLL.[Method]We subgroup healthy adult S-D rats into groups,did operation on C 3~6 level.The first group:laminectomy;the second group:laminectomy and muscle cutting;the third group:muscle cutting only;the fourth group:exposure only;contrasting group:no treatment.We got the tissue of posterior longitudinal,ligament at 1,2,4,and 8 weeks post-operation and quantify BMP-2 and BMP-7 by PCR method.[Result]BMP-2,BMP-7 increased significantly in the 1st,2nd and 3rd group compared with the contrastinggroup;BMP-2,BMP-7 of only exposure group had no significant difference compared with the contrasting group.[Conclusion]BMP-2 and BMP-7 play important roles in the early stage of OPLL,they could be the on-setting factors of OPLL.BMP-7 may play an important roles in the later ossification period.

Objective To compare the effects of honey dressing and silver sulfadiazine dressing for wound healing in burn patients by Meta-analysis.Methods All the randomized controlled trials were collected by searching many kinds of databases in or out of the country to compare honey dressing with silver sulfadiazine dressing for wound healing in burn patients.Review Manager 5.2 was used to analyze the effects.Results Six randomized controlled trials (RCT) were included.Honey dressing was much better than silver sulfadiazine dressing for burn wounds,while there were no significant differences in positive rate of wound swab culture and healing days.Conclusions It can be proved that honey dressing has an advantage over silver sulfadiazine dressing in the wound healing days within 21 and final outcome.Whether honey dressing is superior to silver sulfadiazine dressing in antibacterial effects and healing days remains to be studied with adequate,powerful,high quality randomized controlled trials.

Objective To summarize the correlation between cytotoxic T lymphocyte associated antigen-4 (CTLA-4) promoter-49 A/G polymorphism and Graves' disease (GD)in China.Methods The publications before Sep.30,2011 about the correlation between CTLA-4 promoter-49 A/G polymorphism and GD in China were collected by searching CNKI,CBM,and Wanfang database.Meta-analysis was performed to check the difference of genotypes such as AG,GG,GG + AG,and G allele between GD group and the control group.Results A total of 6 studies involving 570 cases in GD group and 486 cases in the control group were included in the meta-analysis.According to the heterogeneity of these studies,meta-analysis was performed to analyze the correlation between AG,GG,GG + AG genotype,G allele and GD by fixed effects model.The pooled OR value(95％ CI) of various studies was 1.97 (1.37-2.82),3.66 (2.42-5.53),2.55 (1.82-3.58),and 1.99 (1.49-2.65).Conclusion The meta-analysis demonstrates that CTLA-4 promoter-49 A/G polymorphism increases the possibility of getting GD in Chinese.

Objective To investigate the correlation between postoperative intraabdominal adhesions and tumor growth and metastasis and to evaluate the effect of PDLLA. Methods Sixty male Wistar rats were divided into tumor transplantation group ( A group) and non-tumor-transplantation group (B group). Both groups were further subdivided into intraabdominal adhesion model subgroup, PDLLA intervention subgroup and false operation subgroup respectively. Postoperative intraabdominal adhesions and tumor growth and metastasis were semiquantitively scored 4 weeks after the operation. Results The scores of intraabdominal adhesion and the tumor growth and metastasis in all subgroups of tumor transplantation group were higher than that of non-tumor-transplantation group ( P

ObjectiveTo understand the feature of blood pressure in children aged 7 to 12 years in Zhengzhou.Methods According to stratiifed cluster random sampling method, children aged 7 to 12 years in ifve schools from three urban and two suburban counties in Zhengzhou were analyzed. The height, weight, waist circumference, hip circumference, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were measured and analyzed.Results The survey included total 6460 children aged 7 to 12 years, 3206 urban children (49.63%), 3254 suburban children (50.37%), 3525 boys (54.57%) and 2935 girls (45.43%). SBP in boys [(117.86±18.18) mmHg] was signiifcantly higher than that in girls [(113.82±13.11) mmHg (t=3.16;P=0.002). The incidence of hypertension in children in Zhengzhou was 7.52%. The blood pressure in boys was higher than that in girls (χ2=9.66,P=0.002). The blood pressure in urban boys and girls was higher than that in suburban boys and girls respectively (χ2=24.15, 14.39;P=0.000). The SBP and DBP had positive correlation with age, height, weight, BMI, waist circumference in boys (P<0.01). The SBP had positive correlation with age, height, weight, BMI, waist circumference in girls (P<0.01). Conclusions The blood pressure is higher in boys than in girls, which also is higher in urban children than in suburban children in Zhengzhou. The SBP is related to the age, height, weight, BMI, waist circumference.

Objective Boy sexual development is affected not only by age, but also by environment factors .The present study was to survey and evaluate the status of sexual development in boys from Zhengzhou area and to explore their influencing factors. Methods The height, weight, waist circumference, hip circumference, penis and testicles in 3779 boys aged from 6 to 13 years old in Zhengzhou were measured .The penis length and testicular volume of different ages and their influencing factors were compared, and the beginning age and sexual development characteristics were explored .The development of genitalia and pubes were evaluated by Tanner staging criteria and standards, which were divided into five stages. Results There were 3779 boys, including 395 overweight cases (10.45%) and 208 obesity cases (5.50%).The testicular volume and penis length increased by age, which increased slowly at the age of 6 to 11, followed by a rapid increase after the age of 11 year old.Testicular volume increased more rapidly than that of penis length. The medians quartile of testicular volume in overweight group ,obese group and normal group were 2.50 mL, 2.50 mL, 2.00 mL, 2.00 mL,2.00 mL,1.00 mL respectively .The testicular volume in overweight group and obese group were significantly greater than that in nor -mal group (P<0.01) and there were no difference between overweight group and obese group .The penis length in overweight group and obese group were significantly less than that in normal group (P<0.01), and there was no difference between overweight group and obese group.Testicular volume and penis length were positively correlated with age, height, weight, body mass index, waist circumference and hip circumference; the correlation between testicular volume and height, penis length and age were the strongest. The age of development of testicle (average 12.02 years) in urban area was later by 2.73 years than that in the rural area (average 9.9 years), the difference was statistically significant (P<0.001).The age of pubic development (P2) and maturity (P5) was (12.34 ±0.83) years and (12.39 ±1.24 ) years.The incidence of precocity in boys was 0.40%. Conclusion The sexual development of boys from Zheng-zhou area is similar to the results of large scale survey from China .Attention should be paid to the effect of obesity on sexual develop-ment, and early intervention should be given, the occurrence of adverse events of sexual development can be avoided .
