Objective To introduce our experience of treating Pilon fractures with an articulated and spanning external fixator. Methods From February 2002 to June 2004, 19 patients with high energy Pilon fractures (21 sides) were treated with a T- shaped unilateral articulated and spanning external fixator in our department. The fixators were placed medial1y across the ankle joint, and the fixation of fracture was enhanced by a combined use of limited internal fixation. The main causes of injury were traffic accidents and high altitude falling. The distal 2 pins were inserted into the talus and the tuberosity of calcaneus so that the subtalar joint was treated as an axis during ankle movement. At approximately postoperative 2 or 3 weeks, the articular hinge was released and the patient began ankle exercises. The clinical outcomes and complications were investigated and the postoperative X- ray examinations of the ankle were also evaluated. Results 19 patients were followed up for a mean period of 13 months. No infection of wound or pin site, no neurovascular complication or no nonunion was found. According to Baird & Jackson ankle joint scoring system, their functional evaluation of the ankle scored from 72 to 98 (averaging 92). Clinical results were excellent in 4, good in 12, fair in 3 and poor in 2. Reduction of the articular surface was anatomic in 16, fair in 3 and poor in 2 according to Burwell & Charnley classification. Conclusions External fixation with an articulated and spanning fixator combined with limited internal fixation is a satisfying technique to treat Pilon fractures. This technique can restore anatomical articular surface, allow early ankle joint motion, effectively decrease complications of both wound and bone healing, and prevent ankle joint stiffness after fixation.

Objective To analyze the characteristics of death and disease burden of residents in Pingshan District of Shenzhen City from 2019 to 2020 and provide data support for disease prevention and control. Methods The data of death surveillance and demography were collected. The causes of death were classified and coded according to ICD-10. The crude mortality, standardized mortality and potential years of life lost were calculated. Results From 2019 to 2020, 910 people died in Pingshan district.The average age of death was 64.94(47.06 - 82.34) years, the crude mortality was 102.04/100 000, the standardized mortality was 263.97/100 000, and the average life expectancy was 86.00 years. 558 men died and 352 women died , the crude mortality were 113.72/100 000 and 87.76 /100 000 , the standardized mortality rate 313.05/100 000 and 211.97/100 000 ; the average life expectancy were 84.66 years and 87.55 years . The crude mortality of male was higher than that of female (χ²=14.594, P<0.001). The standardized mortality of men was also higher than that of women. The top three causes of death in the whole population, men and women were circulatory system diseases, malignant tumors, diseases and injury from high to low. And the top three diseases with standardized potential life lost years and standardized potential life lost rate from high to low were injury, circulatory system diseases and malignant tumors. Conclusion Circulatory system diseases, malignant tumors, injury are the main causes of death and the three kinds of diseases with the heaviest disease burden in Pingshan District of Shenzhen city. Men are the key population for prevention and control. The prevention and control of the above three kinds of diseases should be done to reduce the mortality of local population.

OBJECTIVES: To investigate the differences in non-suicidal self-injury (NSSI) behaviors between only-child and non-only-child adolescents with mood disorders. METHODS: A three-stage sampling method was used to perform a cross-sectional survey of 529 adolescents, aged 12-18 years, who had mood disorders and NSSI behaviors. These adolescents were sampled from the outpatient service of 20 mental hospitals in 9 provinces of China from August to November 2020. A self-made questionnaire was used to collect general demographic data. The Functional Assessment of Self-Mutilation, Beck Scale for Suicide Ideation, Kessler Psychological Distress Scale, Stress Mindset Measure-General, Multidimensional Scale of Perceived Social Support, Multidimensional Students' Life Satisfaction Scales, and Rosenberg Self-Esteem Scale were used to collect the information on self-injury behaviors and psychological factors in these adolescents. RESULTS: A total of 529 adolescents with mood disorders and NSSI behaviors were surveyed, among whom 375 were only-child adolescents and 154 were non-only-child adolescents. Compared with the non-only-child group, the only-child group had a significantly higher total score of Functional Assessment of Self-Mutilation (P<0.05) .The type and frequency of self-injury in the only-child group were significantly higher than those in the non-only-child group (P<0.05). Psychological analysis showed that compared with the non-only-child group, the only-child group had a significantly lower score of self-esteem (P<0.05) and significantly higher scores of psychological distress and depressive symptoms (P<0.05). The multiple linear regression analysis showed that the score of suicidal ideation was positively correlated with the frequency of NSSI behaviors in both only-child and non-only-child adolescents with mood disorders (P<0.05); in the only-child adolescents, the level of self-esteem was negatively correlated with the frequency of NSSI behaviors (P<0.05), and the score of stress perception was positively correlated with the frequency of NSSI behaviors (P<0.05); in the non-only-child adolescents, the score of anxious emotion was positively correlated with the frequency of NSSI behaviors (P<0.05). CONCLUSIONS Among the adolescents with mood disorders and NSSI behaviors, the only-child adolescents tend to have a higher frequency of self-injury and poorer mental health, and therefore, the only-child adolescents with mood disorders and NSSI behaviors need more attention.

OBJECTIVETo evaluate safety and immunogenicity of inactivated hepatitis A vaccine in HBsAg carriers and healthy children.

METHODSOne hundred and twenty-one healthy children and ten HBsAg carriers, aged 1-10 years HAV susceptible were enrolled in the study. The inactivated hepatitis A vaccine was produced by Tangshan Biogenetic Company. The dosage of the vaccine was 1000 U/Dosage and 500 U/Dosage. The vaccination schedule was six month apart for two injections. The serum anti-HAV level was detected with EIA at one month after first injection and at one and six month after the booster injection, respectively.

RESULTSThe anti-HAV appeared in all the children. One month after the booster injection, the serum anti-HAV level in children vaccinated 500 U/Dosage was 4684.9 mIU and 4535.6 mIU, respectively and in the children vaccinated 1000 U/Dosage, 5399.8 mIU and 7347.1 mIU, respectively. The anti-HAV level was not statistically different between the two groups of children. There was no adverse reaction after the vaccination. The anti-HAV level was still high one year after first injection.

CONCLUSIONSThe data indicated that the safety and immunogenicity of the domestic inactivated hepatitis A vaccine were excellent in both groups of children.
