This paper reported 13 cases of delayed traumatic chest wall abscess from January 2012 to January 2015.All the patients were associated with type 2 diabetes.After local puncture for confirmative diagnosis, a chest wall abscess dissection was carried out as soon as possible.At each site of upper and lower pole, an indwelling drainage tube was placed for irrigation and negative pressure suction.Sensitive antibiotics were selected based on susceptibility test results.The drainage tubes were removed 7-14 days after surgery.There were 8 cases of primary healing of incision and 5 cases of secondary healing of incision.All the patients were cured.Follow-ups for 6-36 months (average, 17 months) showed no recurrence.

2 months) was 93%(14/15); both 1- and 2-year local control rates were 83%; and 1- and 2-year survival rates were 72.9% and 62.5%, respectively. The median survival time was 32 months. Three patients had distant metastasis. Five patients died of lung metastasis (1 case) or multiple organ failure (4 cases). No complication or side-effect was observed in the patients, except skin ulceration in one patient. Conclusions Interstitial implantation of ~(125)I seed combined with or without external beam radiation therapy is convenient, effective, safe, and minimally invasive for soft tissue tumor, especially for metastatic or recurrent tumors.

Objective To study possible mechanisms of oxidative damages in rat lung type Ⅱ cells induced by cooking oil fume (COF). Methods The rat type Ⅱ lung cells were pretreated with anti_oxidant N_acetylcysteine (NAC) for 30 miuntes and were exposed to COF for 12 hours. The contents of MDA and GSH were detected with thiobarbituric acid colorimetric assay and 5,5_dithiobis 2_nitrobenzoic acid colorimetric assay. Results The significant increase of the contents of MDA and significant decrease of the contents of GSH were observed in the rat lung type Ⅱ cells with the increase of exposure doses of COF and the prolongation of exposure time of COF. The pretratment of NAC could reduce the production of MDA and increase the contents of GSH of the cells. Conclusion The possible mechanisms of oxidative damages in rat lung type Ⅱ cells induced by cooking oil rume might be formation of lipid peroxidation and interference of GSH anti_oxidative systems of the cells.

Objective To investigate the effect of electro-acupuncture at Guanyuanshu, Xinshu, Neiguan points on cardiac function after acute myocardial ischemia in rabbits. Methods A total of 36 rabbits were randomly divided into a control group, a model group and a treatment group. Acute myocardial ischemia was induced with Jugular vein injection of pituitrin. At 10 min before modeling, 1 hour and 1 week after modeling, the levels of malondialdehyde (MDA) and creatine kinase(CK) were determined respectively, the cardiac function was assessed as the maximum rate of left ventricular pressure rise(dp/dtmax)and the peak left ventricular pressure (LVSP). Results After 1 week of treatment, the serum levels of CK and MDA in the treatment group reduced significantly(120.21±10.67 U/L, 21.35±2.04 mmol/L], compared to the model group (162.37±13.21 U/L, 30.13±2.75 mmol/L) (all P<0.05);the dp/dtmax and LVSP decreased percentage in the treatment group (20%±2.43%, 7.22%±0.97%) decrease significantly compared to the model group (31.5%± 4.14%, 12.19%±2.21%) (all P<0.05). Conclusion Electro-acupuncture of Guanyuanshu, Xinshu, Neiguan acupoints can significantly improve cardiac function after acute myocardial ischemia and protect against acute myocardial ischemia in rabbits.

Objective To explore the factors affecting the prognosis for a child in a persistent vegetative state (PVS).Methods Forty-three PVS children were selected and provided with comprehensive rehabilitation training.It included physical therapy such as Rood approach and range of joint movement training,medication and hydro-acupuncture at the head points.After three months,each patient's state of consciousness was quantified,and multiple-factor unconditional logistic regression was conducted to identify factors relating to any changes.Results By the end of the intervention,29 of the patients had regained consciousness,a recovery rate of 67％.Logistic regression revealed that age,brainstem auditory evoked potentials (BAEP) and PVS score at admission all were closely related with whether a child regained consciousness.Gender,type of damage,EEG score,and the initial time of intervention had no significant relationship with regaining consciousness.Conclusions Older PVS patients with higher BAEPs and PVS scores at admission are more likely to regain consciousness.

Objective To investigate the relationship between the expression of Toll-like receptor 4 (TLR4) on mononuclear cells in peripheral blood and changes of serum vitamin D level in children with bronchiolitis.Methods The children who were diagnosed as bronchiolitis and received treatment in the Second Affiliated Hospital of Harbin Medical University from October 2013 to January 2014 were chosen as the pre-treatment group,and then divided them into moderate group and severe group according to the clinical symptoms,20 cases for each group.Then the cases in pre-treatment group who recovered after treatment were recruited as the after-treatment group,and the children who were healthy and medical examination in the Second Affiliated Hospital of Harbin Medical University in the same period were recruited as the healthy control group.The expressions of TLR4 on CD14 labeled mononuclear cells in the periphera were measured by flow cytometry.The level of 25 (OH) D in serum was detected by enzyme linked immunosorbent assay (ELISA).Results (1) The expression level in children with bronchiolitis of TLR4:the mode-rate group [(18.98 ±2.29)％] and severe group [(30.13 ±2.13)％] increased significantly (P ＜0.05) compared with control group [(1.17 ± 0.57) ％].And the expression level of moderate group [(2.02 ± 0.48) ％] and severe group [(11.43 ± 1.52) ％] decreased significantly after treatment (P ＜0.05).(2) Serum vitamin D level in children with bronchiolitis of the moderate group[(17.16 ± 3.34) μg/L] and severe group [(6.56 ± 2.28) μg/L] were lower than healthy control group [(53.69 ± 20.18) μg/L] before treatment (P ＜ 0.05),especially the severe group [(6.56 ±2.28) μg/L].The level of moderate group [(9.59 ± 2.31) μg/L] and severe group [(4.70 ± 0.67) μg/L] became lower after treatment (P ＜ 0.05).(3) Both severe group (r =-0.491,P ＜ 0.05) before treatment and moderate group (r =-0.436,P ＜ 0.05) after treatment showed negative correlation between TLR4 on mononuclear cells in peripheral blood and serum 25 (OH)D level in children with bronchiolitis.And no correlation was found among healthy control group,moderate group before treatment and severe group after treatment (P ＞ 0.05).Conclusions The conditions of children with bronchiolitis was positively correlated with the expression level of TLR4,and negatively correlated with the vitamin D level.The serum 25 (OH) D decreased steadily during the treatment.The expression of TLR4 in monocytes has a certain correlation with the level of vitamin D in children with bronchiolitis.
