Objective To compare the efficacy of internal fixation with non-operative treatment of traumatic flail chest combined with sternal fracture.Methods A retrospective review was made on 102 patients with traumatic flail chest combined with sternal fracture treated from January 2007 to January 2014.There were 71 patients in operation group and 31 patients in non-operation group.Operation group was allocated to pure titanium rib plating (Group Ⅰ,22 cases),porous titanium screw fixation (Group Ⅱ,20 cases),and nickel-titanium memory alloy sternal rib plating (Group Ⅲ,29 cases).Rib traction was performed in non-operation group.Clinical results and incidence of complications were compared between the two groups.Results At 24 and 72 hours,operation group was superior over non-operation group with regard to HR [(100.4 ± 9.5) times/min vs (105.2 ± 10.1) times/min,(92.1 ± 9.9) times/min vs (102.1 ± 9.2) times/min],MAP [(97.7 ± 14.5) mmHg vs (91.0 ± 13.3) mmHg,(112.5 ± 15.2) mmHg vs (93.1 ± 13.8)mmHg] and CVP [(7.8 ±3.7)cmH2O vs (9.4 ±3.8)cmH2O,(6.2 ±2.9)cmH2O vs (9.1 ±3.2) cmH2 O] (P ＜ 0.05).Duration in ICU [(5.1 ± 0.8) days vs (9.3 ± 1.1) days],ventilation time [(4.5 ±1.0)days vs (8.2 ± 1.4)days],hospitalization time [(14.6 ±3.5)days vs (23.3 ±4.4)days] and incidence of complications were significantly lower in operation group than in non-operation group (P ＜ 0.05).Two months after discharge,tidal volume (VT) [(0.52 ±0.04)L vs (0.40 ±0.03)L],inspiratory capacity (IC)[(1.99 ±0.45)L vs (1.22 ±±0.33)L],forced vital capacity (FVC) [(3.52 ±0.51)L vs (2.44 ±0.42)L],total lung capacity (TLC) [(5.41 ±0.82)L vs (3.72 ±0.56)L] and forced expiratory volume in one second (FEV1) [(2.80 ± 0.43) L vs (1.95 ± 0.50) L] showed significantly better results in operation group than in non-operation group (P ＜ 0.05).Operation time,intraoperative bleeding and daily drainage volume were (38.8 ±9.2)min,(43.5 ±7.6)ml and (10.9 ± 1.1)ml in Group Ⅱ versus (62.5 ± 10.1)min,(100.0 ± 10.5) ml and (26.8 ±3.1)ml in Group Ⅰ and (49.3 ±9.6)min,(61.4 ±8.3)min and (19.8 ±1.6)ml in Group Ⅲ (P ＜ 0.01).Conclusion For traumatic flail chest combined with sternal fracture,the internal fixation should be done as early as possible so as to reduce incidence of complications.Relatively,porous titanium screw fixation has better clinical outcome.

ObjectiveTo investigate the characteristic of pathology in Chinese patients with Nonaka myopathy.MethodsThirteen patients (7 males and 6 females) diagnosed with Nonaka myopathy in our laboratory from January 2002 to March 2011 were included in this study.Their mean age was 39.5 years old and the mean duration of illness was 4.15 years.The most common symptoms were weakness of raising feet with sparing of quadriceps femoris muscles in the early stage of disease.One patient presented the initial symptoms of upper limb weakness. Muscles biopsies were obtained from all these 13 patients. Histology study including immunohistochemical (IHC) staining with antibody against amyloid 3,phosphorylated tau protein,ubiquitin,glucose-regulated protein of molecular weight 78 000(GRP78),calnexin,caspase-12and Bax were performed.Skeletal muscle samples from 3 chronic fatigue syndrome patients,2 myofibrillar myopathy patients were used for control in the IHC staining. All coding exons of uridinediphospho-N-acetylglucosamine 2-epimerase gene were directly sequenced in genomic DNA from these patients.Results The main pathological changes of tibialis anterior muscle in 12 cases were muscle dystrophy with rimmed vacuoles.The rimmed vacuoles were positive for anti-β-amyloid,tau protein and ubiquitin in IHC studies.In the atrophy fibers,IHC showed the increased expression of endoplasmic reticulum stress related proteins GRP78 and calnexin,and apoptosis proteins of caspase-12 and Bax.ConclusionsThere is accumulation of abnormal proteins in muscle fibers in Chinese patients with Nonaka myopahty.These proteins may stimulate endoplasmic reticulum stress and apoptosis,which may be a mechanism responsible for muscle damage.

Objective To investigate the relationship between neurokinin B (NKB), endothelin-1 (ET-1) and the pathogenesis of hypertensive disorder complicating pregnancy (HDCP). Methods 22 HDCP, who received antenatal examination in the Department of Obstetrics and Gynecology of Union Hospital of Tongji Medical College in Huazhong University of Science and Technology from March to July in 2005, were selected for the study, including 12 gestational hypertension (gestational hypertension group) and 10 preeclampsia (preeclamptic group); 22 normal pregnant women in the same period were served as control. At different gestational weeks, maternal plasma levels of NKB and ET-1 in three groups were detected by enzyme-linked immunoassay technique, the expression and location of NKB in placenta were examined by immunohistochemical SP, and mRNA expressions of NKB and ET-1 in placenta were measured with RT-PCR method. Results (1) At 10 - 14, 20 - 24, and 30 - 34 gestational weeks, the plasma levels of NKB and ET-1 in preeclamptic group were ( 35. 6±5.2), ( 17. 9±4. 3), (39. 5±4. 3 ), (22. 7± 3.6), (47. 1±3. 3) and (27.5±3.5) μg/L, respectively; in the control group they were (22. 9±3. 3), (10.7±5.3), (30.2±3.4), (13.2±4.1), (34.6±4.3) and (16.6±4.8) μg/L, respectively. There was a significant difference between preeclamptic group and control group ( P < 0. 05), while there was no significant difference between gestational hypertension group and control group (P>0.05).(2) Immunohistochemical staining for NKB protein was observed in all groups and was located in the villous syncytintrophoblast and villous vascular endothelial cells as well as cytoplasm of stromal cells, mostly located in villous syncytiotrophoblast. The expressions of NKB in placenta of preeclamptic group (0.244±0.020) was significantly higher than that in control group (0. 160±0. 012), with a significant difference between the two groups (P<0.05 ). However, there was no significant difference between gestational hypertension group (0.162±0.019) and control group (P>0.05). (3) The transcription levels of the NKB mRNA (0. 97±0. 36) and ET-1 mRNA (0. 90±0. 36) in preeclamptic placentas were both significantly higher than those in control groups (0. 78±0. 54, 0. 65±0. 47, respectively ), with a significant difference between the two groups( P <0. 05 ). But there was no significant difference between gestational hypertension group (0. 80±0. 40, 0. 70±0. 32, respectively) and control group (P >0. 05). (4) There was an evident positive correlation between plasma NKB and ET-1 levels in preeclampsia ( r =0. 79, P < 0. 05 ). Conclusions The significantly increased maternal plasma levels of NKB and ET-1 of patients with preeclampsia occur at early pregnancy (10 -14 gestational weeks) before the onset of clinical symptoms. The change of maternal plasma levels of NKB and ET-1 is closely related to pathogenesis of HDCP.

Objective To investigate the influence of a multifaceted stroke telehome-care (THC) on extremities function, activities of daily living (ADL) and quality of life in stroke patients with hemiplegia. Methods A total of 52 stroke survivors in department of neurology were randomized to the THC intervention or usual care. The patients in the control group received conventional care, while those in the intervention group were additionally given a THC program over 3 months. The THC intervention includes motor imagery and adaptive strategies. Data collection was undertaken using the Fugl-Meyer Motor Assessment Scale (FMA), the Barthel Index (BI), the Stroke Impact Scale (SIS) at baseline, 3 months, and 6 months. Results At baseline, the scores of FMA, BI, and SIS in the intervention group were 53.62 ± 23.52, 54.04 ± 17.44, 179.96 ± 28.51, and while the scores of the control group were 50.96 ± 19.52, 49.46 ± 15.09, 169.23 ± 28.48. There were no pre-existing differences on any scale between the two groups (t=0.443, 1.012, 1.358, P > 0.05). At 3 months, the scores of FMA, BI, SIS in the control group were 53.54 ± 17.45, 50.77 ± 14.47, 76.19 ± 27.78, and were significantly lower than 78.38 ± 12.54, 74.62 ± 11.22, 228.54±22.63 in the THC group (t=5.895, 6.641, 7.449,P<0.01). At 6 months, the scores of FMA, BI, SIS in the control group were 57.88±17.89, 59.08±13.85, 183.92±26.56, and were significantly lower than 90.58 ± 9.60, 86.54 ± 9.88, 252.19 ± 20.10 in the THC group (t=8.211, 8.233, 10.451, P < 0.01). Conclusions A telehome-care program that provide distance training and education of disabled persons resulted in greater improvements in physical functioning, ADL and quality of life.

Objective:To explore diagnostic effects of 24h dynamic electrocardiogram (DCG) on pacemaker-induced rapid arrhythmias of different locations.Methods: Clinical data of 86 patients, who received pacemaker implantation in our hospital from Feb 2013 to Jan 2016, were retrospectively analyzed.According to ventricular electrode placement location, patients were divided into right ventricular septum (RVS) pacing group (RVS group, n=43) and right ventricular apex (RVA) pacing group (RVA group, n=43).The Tp-Te interval and occurrence of arrhythmias detected by 24h DCG were recorded and compared between two groups.Results: All patients received pacemaker implantation successfully, and pacemaker was fixed on RVS or RVA.There were no significant difference in pacing threshold, impedance and R wave amplitude between two groups, P>0.05 all.Compared with RVA group, there were significant reductions in Tp-Te intervals of V3 lead [(102.78±19.24)ms vs.(94.39±18.56)ms] and V4 lead [(96.39±13.11)ms vs.(85.87±14.59)ms] in RVS group (P=0.001 both).There were no significant difference in incidence rates of sinus arrest, II° sinoatrial block, atrioventricular block, atrial premature beats, transient paroxysmal atrial tachycardia and ventricular premature beats between two groups (P>0.05 all).Conclusion: The 24h DCG indicates that compared with RVA pacing, the Tp-Te interval of RVS pacing group significantly shorten, it may can better protect cardiac function.

Objective To explore the role of homocysteine(Hcy)on angiogenesis at peri infarct region after focal cere-bral ischemia in rats, to elucidate inhibitory factors of angiogenesis, and to establish a clinic foundation for clinical brain functional recovery. Methods Spragur-Dawley (SD) male rats (n=36) were randomly divided into three groups with 12 rats in each group including Sham Operation (SO) group, Middle cerebral artery occlusion (MCAO) group and MCAO+Hcy group. The rats in Sham and MCAO groups were intra-peritoneally injected with 5 mL/(kg·d) saline and rats in MCAO+Hcy group were injected with 2%5 mL/(kg·d) Hey solution from the same route. MCAO was introduced by intraluminal filament meth-od after 7 d Hcy intervention. Rat brains were harvested on the 7th day after MCAO. BrdU(50 mg/kg, as a marker of cell pro-liferation)was intraperitoneally injected three days before the rats were killed. High performance liquid chromatography (HPLC)was used to measure serum Hcy concentration in rats. Brain infarction size was observed by TTC staining. Immuno-fluorescence staining was used to detect the number of BrdU+/laminin+cells at the thalamus of infarction side. Results Se-rum Hcy concentration significantly higher in MCAO+Hcy group than in SO and MCAO groups(P<0.05). Brain damage increased and the number of BrdU+/laminin+cells decreased in MCAO+Hcy group compared with those of MCAO group (P<0.05). Conclusion Increased Hcy concentration in rats lead to more severe damage of cerebral infarction as well as to inhibit the angiogenesis at surrounding ischemia area.
