BACKGROUND:With the development of AO, the treatment of intercondylar humeral fractures with open reduction has been a trend. However, the methods of fixation become many. There is no conclusion of which method is optimal.
OBJECTIVE:To investigate the clinical effect of two kinds of different fixation methods (Y-type steel plate and double steel plate) for intercondylar humeral fractures via different surgical approaches.
METHODA retrospective analysis of clinical data of 86 cases of fresh intercondylar humeral fractures in the Department of Orthopedics, Sixth Affiliated Hospital, Xinjiang Medical University, between December 2003
and May 2014 were conducted in this study. According to the different fixation materials, patients were divided into two groupdouble steel group (n=44, including the surgical approach of ulna olecranon osteotomy which had 22 cases and the surgical approach of triceps V shaped severance which had 22 cases), Y-type steel group (n=42, including the surgical approach of ulna olecranon osteotomy which had 21 cases and the surgical approach of triceps V shaped severance which had 21 cases). The clinical curative effect and related complications of the two groups after operation were analyzed. During fol ow-up, modified Cassebaum elbow scoring system was used to evaluate the excellent and good rate of therapy.
RESULTS AND CONCLUSION:After fol owed up for 12-36 months, the total excellent and good rate of Y-type steel plate was 76%and the total excellent and good rate of double steel plate was 77%. There were no significant differences between the two groups (P>0.05). But interestingly, the surgical approach of ulna olecranon osteotomy was better than the surgical approach of triceps V shaped severance and the difference was statistical y significant (P<0.05). Above data suggested that Y-type steel plate and double steel plate were effective ways in the repair of intercondylar humeral fractures. However, for different surgical approaches, the surgical approach of ulna olecranon osteotomy was better than the surgical approach of triceps V shaped severance.

Objective To investigate the relationship between tumor necrosis factor-alpha (TNF-α) and development of chronic obstructive pulmonary disease (COPD).Methods COPD patients and controls were divided into three groups: COPD group (n=66), smoker control group (n=42) and health control group (n=23). COPD group was further divided into the serious group (n=23) and non-serious group (n=43). The concentration of TNF-α of all cases was detected by human Th1/Th2 cytokine kit.Results The concentration of TNF-α in the COPD group was significantly higher than that of the smoker and healthy groups ( P<0.01). Furthermore, compared to non-serious COPD group, the concentration of TNF-α was higher in the serious COPD group ( P<0.05).Conclusion The concentration of TNF-α might be related with the pathogenesis and development of COPD.

Objective To observe the effect of hydrocolloid dressings with instant ice compress on the healing process,postoperative pain and efficacy of patients with acne scar treated by 2940 nm erbium pixel laser.Methods We selected 60 patients with acne scar from November 2012 to June 2014 treated by the erbium pixel laser.They were randomly divided into two groups:hydrocolloid dressings with ice compress after treatment were used in observation group (n=37)and postoperative wound dry were kept in control group (n=23);pain,duration of burning,erythema duration,efficacy,decrustation time,postoperative complications were evaluated and quantitatively analyzed.Results Compared with the control group,the application of hydrocolloid dressings with ice compress group (observation group) received less postoperative paim postoperative VAS pain score was (5.81± 0.64) in observation group and (6.09±0.69) in control group;duration of burning was shorter:(1.86± 0.75) h in observation group and (3.65±0.93) h in control group;duration of erythema was shorter:(2.27±0.73) d in observation group and (3.52 ±0.79) d in control group;decrustation time was shorter:(5.76± 1.06) d in observation group and (8.09±0.95) d in control group;postoperative complications were reduced:(5.4％,2/37) in the observation group and (30.4％,7/23) in the control group,with statistically significant difference (all P＜0.05).The differences were not statistically significant in the intraoperative VAS score and the curative effect.Conclusions The application of hydrocolloid dressing with instant ice compress after erbium pixel laser in the treatment of acne scar can effectively reduce postoperative pain and burning sensation,shorten the duration of erythema and crusting time after operation.It also reduces the incidence of complications.

Objective To investigate the value and effects of lipoinjection into the subperiosteal and overlying multiple planes for correction of facial depression.Methods The lateral and posterolateral areas of the thigh and infragluteal areas were selected as donor sites of autologous fat.The fat was rinsed and purified after liposuction.The collected fat was injected into the subperiosteal and overlying multiple planes to correct facial depression.Results 96 patients received lipoinjection of volume between 0.5 to 22 ml for each unilateral depression each time.Secondary injection was performed after 4 to 8 months after operation if necessary.The depression was corrected,the skin texture was improved,the wrinkles were also improved after fat transplantation.The follow-up period was between 6 and 24 months.3 patients had sclerosis after lipoinjection.The sclerosis disappeared after 6 months through local massage,hot compress,and traditional medicine treatment in two of them.The sclerosis was resolved by excision in the rest one.There were no complications of hematoma,infection,liquefaction,and calcification.Conclusions Lipoinjection into the subperiosteal and overlying multiple planes can correct facial depression with fat.Fat survival rate is high.The method is suitable for correction of facial depression in aesthetic plastic surgery.

Objective There is close relationship between ubiquitin-specific protease 9X(USP9X) and the biological behav-ior of some tumor.The aim of this study is to investigate the expression and clinical significance of USP 9X in pancreatic carcinoma of elderly patients. Methods The expression of USP9X was detected in 30 pieces of surgically resected primary pancreatic carcinoma tissue and adjacent nontumorous pancreatic tissue of elderly patients by streptavidin -perosidase immunohistochemical method . Results The rate of USP9X positive expression was 56.7%, there was not positive expression in adjacent nontumorous pancreatic tissue .There was no relation between the expression of USP 9X with gender, age, the tumor positin, the tumor size and degree of differentiation (P>0.05), while it was significantly correlated with lymph node metastasis and TNM stages (P<0.05).By using Cox proportional haz-ards analysis, multivariable analysis revealed that TNM stages , lymph node metastasis and USP9X expression were independent risk factor(P<0.05). Conclusion The results indicated that USP9X may play a role in the pathogenesis and prognosis of pancreatic cancer of elderly patients .

Objective To investigate the executive function of children with different sports training. Methods Forty children with Ping-Pong training (Ping-Pong group) and 41 children with swimming training (swimming group), aged 6-9 years, completed GO/NOGO task. Behavioral data (reaction time and accuracy) and event related potential component N2 were collected and analyzed. Results The reaction time was significantly faster and accuracy significantly lower of GO task and NOGO task in swimming group than in Ping-Pong group (P<0.05 and P<0.01). There were significant differences in the amplitude of NOGO-N2 on site CPz between swimming group and Ping-Pong group[(-11.36±9.4) μV vs (-7.55±7.99) μV, P<0.05]. Conclusion The inhibitory function of children with Ping-Pong training is stronger than those with swimming training.
