Objective To evaluate the effect of anterior minimally invasive plate osteosynthesis (MIPO) for treatment of middle humeral shaft fracture.Methods From November 2011 to March 2014,10 cases of middle humeral shaft fracture were treated using MIPO via the anterior approach (MIPO group).Another 26 cases treated by open reduction and internal fixation (ORIF) of the middle humeral shaft fracture between October 2010 and March 2014 were included as controls (ORIF group).Fracture fixation using the 4.5 mm locking compression plate (LCP) was performed in both groups.Parameter measurements included operative time,intraoperative fluoroscopy times,grafting rate,intraoperative blood loss,postoperative drainage,hospital stay,bone healing time and complications.Results MIPO and ORIF groups differed significantly with respect to intraoperative blood loss [(93.5 ± 25.6) ml vs (325.3 ± 158.3) ml],intraoperative fluoroscopy times [(13.2 ± 6.1) vs 4.0 (0-6.0)] and hospitalization [(11.9 ± 1.7)days vs (18.0 ±4.7)days] (P ＜0.05).Bone grafting and drainage were not performed in MIPO group,while bone grafting rate was 54％ and postoperative drainage volume was (120.4 ± 69.6) ml in ORIF group (P ＜0.05).MIPO and ORIF groups were comparable with respect to operative time [(79.0 ± 22.0) min vs (97.5 ± 30.8) min],bone healing time [(15.2 ± 2.5) weeks vs (18.2 ± 4.8)weeks] and postoperative complications (10％ vs23％) (P＞0.05).Conclusion Anterior MIPO is an effective procedure for treatment of middle humeral shaft fracture,with advantages of small trauma,less bleeding,low risk of nerve injury and high rate of fracture healing.

BACKGROUND:The non-specific immune suppression method is generaly used for treatment of systemic lupus erythematosus, but poor prognosis, such as infection and high recurrence rate, exists.
OBJECTIVE:To evaluate the therapeutic effect of bone marrow mesenchymal stem cel transplantation on systemic lupus erythematosus in mice.
METHODS:Sixteen mice with systemic lupus erythematosus were equivalently randomized into control and experimental groups, or then subjected to passage 3 bone marrow mesenchymal stem cel transplantation or the equal volume of normal saline via the tail vein, respectively. Mouse urine samples were colected to detect urine protein levels by Bradford method. Blood samples from the tip of the mouse tail were extracted to detect serum anti-ds-DNS antibody concentration by radioimmunoassay. Mouse kidney tissues were taken and observed pathohistologicaly through hematoxylin-eosin staining and immunohistochemistry staining under microscope. Flow cytometry was used to detect the expression of CD4+CD25+T cels in the inner canthus blood, fresh spleen and thymus.
RESULTS AND CONCLUSION:Within 10 weeks after cel transplantation, the urine protein levels in the two groups were gradualy increased, and the rising velocity was higher in the control group than in the experimental group. From the 4th to 10th week, the urine protein levels in the experimental group were significantly lower than those in the control group (P < 0.05). In the control group, lymphocyte infiltration was visible in the kidney tissues with a few of plasmocytes, and pathological findings showed the mice presented with interstitial nephritis; in the experimental group, the mice had no pathological changes in the kidney. In the two groups, immune complexes were found in the mesangial area, which showed a patch-like distribution in the control group and a punctate distribution in the experimental group; the relative proportion of the occupied area in the experimental group was significantly lower than that in the control group. The expression level of CD4+CD25+T cels in the blood and thymus were significantly higher in the experimental group than the control group (P < 0.05), and the expression level of CD4+CD25+T cels in the spleen was slightly higher in the experimental group than the control group with no significant difference (P > 0.05). The serum anti-ds-DNA antibody concentration in the experimental group was significantly lower than that in the control group (P < 0.05). Taken together, bone marrow mesenchymal stem cel transplantation can improve the pathological damage in systemic lupus erythematosus mice, and has a certain therapeutic effect on systemic lupus erythematosus.

Objective To study the theraputic effect of cyclophosphamide,glucocorticoid combined with sildenafil on pulmonary hypertension in systemic lupus erythematosus(SLE?PAH) patients,and to analyze the prognosis adverse factors.

Objective To explore the predictive values of the levels of procalcitonin (PCT) and thyroid hormone on the prognosis in patients with systemic inflammatory response syndrome (SIRS) complicated with euthyroid sick syndrome (ESS) and their values on differential diagnosis of ESS. Methods A total of 238 patients with SIRS hospitalized in the Emergency Department, Jiangsu Provincial Hospital of Integration of Chinese and Western Medicine, Jiangsu Branch of China Academy of Chinese Medical Sciences from July 2012 to December 2014 were divided into two groups: death group (31 cases) and survival group (207 cases), 182 patients being complicated with ESS and 56 patients without ESS. The differences in the levels of PCT, free triiodothyronine (FT3) and acute physiology and chronic health evaluation (APACHE Ⅱ) score in patients with different clinical outcomes were analyzed. The effects of the inflammatory mediators including levels of PCT, interleukin-6 (IL-6), C-reactive protein (CRP), and thyroid function such as free thyroxine (FT4) and thyroid stimulating hormone (TSH) on clinical outcomes and their predictive values on death of emergency patients with SIRS were also studied. Furthermore, the correlations between APACHEⅡscore and PCT, IL-6, CRP, thyroid hormone were analyzed. Results The level of PCT and APACHE Ⅱ score in death group were significantly higher than those in survival group [PCT (ng/L): 8.38 (13.88) vs. 1.04 (3.57), APACHEⅡscore:27.42±6.88 vs. 16.35±6.72, both P<0.01], while FT3 level was obviously lower in death group (pmol/L: 2.19±0.58 vs. 3.07±0.94, P < 0.05). No significant differences in levels of IL-6, CRP, FT4 and TSH were observed between the two groups (all P>0.05). The mortality was increased markedly in patients with higher PTC level and lower FT3 level compared with normal PCT level and normal FT3 level [18.8% (30/160) vs. 1.3% (1/78), 17.1%(31/181) vs. 0 (0/57), both P<0.05]. However, the abnormalities of IL-6, CRP, FT4 and TSH levels did not contribute to patient's mortality (all P>0.05). PCT was positively correlated with APACHEⅡscore (r>0.33, P<0.001), while FT3 was negatively correlated with APACHEⅡscore (r<-0.33, P<0.001). There were no correlations between IL-6 (r = 0.319, P < 0.001), CRP (r = 0.161, P < 0.05), FT4 (r = -0.170, P < 0.01), TSH (r = -0.057, P = 0.385), and APACHEⅡscore. The levels of PCT, IL-6 and CRP and APACHEⅡscore in patients with ESS were significantly higher than those in patients without ESS [PCT (ng/L):2.54 (5.90) vs. 0.20 (0.43), IL-6 (ng/L):98.62 (351.20) vs. 16.85 (33.60), CRP (mg/L):88.00 (110.50) vs. 25.50 (48.00), APACHEⅡscore:17.62±8.17 vs. 10.98±4.97, all P<0.01]. The cut-off values for predicting patient's death of these indexes showed by receiver operating characteristic curve (ROC curve) analysis were as follows: PCT: cut-off value ≥ 1.755 ng/L, sensitivity: 87.1%, specificity: 58.0%, area under the ROC curve (AUC): 0.802; FT3: cut-off value ≤ 2.92 pmol/L, sensitivity: 93.5%, specificity: 54.1%, AUC: 0.785;APACHE Ⅱ score: cut-off value ≥ 21.5, sensitivity: 83.9%, specificity: 88.4%, AUC: 0.920. Conclusions The levels of serum PCT, FT3 and APACHEⅡscore are prognostic factors in patients with SIRS. Meanwhile, the levels of serum PCT, IL-6, CRP and APACHE Ⅱ score should be taken into consideration in differential diagnosis of ESS in patients with SIRS.
