ABSTRACT

Malignant tumors usually have no obvious clinical symptoms in the early stage. Most patients are already in the advanced stage when they are diagnosed. Some patients have lost the opportunity for operation, resulting in poor prognosis. Therefore, how to find the best therapeutic target for such patients and improve the prognosis of patients has gradually become the focus of scholar′s attention. Recently, Kruppel-like factor (KLF) is a transcriptional regulator that can bind to the target DNA, and its family plays an important role in the occurrence and development of malignant tumors. It has also been confirmed that the KLF family affects the proliferation, differentiation and migration of tumor cells, but the specific mechanism is still not fully elucidate. Consequently, in order to further explored the effect of the KLF family on tumors, this study intends to briefly review the roles and regulatory mechanisms of the KLF family in the cell proliferation, differentiation and migration of malignant tumors, hoping to provide new target for the biological treatment of tumors.

ABSTRACT

Objective To observe the effects of proximal gastric electrical stimulation (GES) on body weight and gastrointestinal motility in SD rats,and investigate the regulation of gastric nerve stimulation and serum gastrointestinal hormones by neuro-humoral regulation.Methods 12 SD rats were divided into experimental group (n =6) and control group (n =6),with gastric electrical stimulator implanted,and in experimental group dual-channel GES was activated.General status was observed for 4 weeks after GES activation,including body weight,feeding and water intake,urine and stool volumes,the resting gastric volume and gastric emptying were monitored via the establishment of intestinal fistula,and serum gastrointestinal hormones change was detected.Results During 4-week GES process,one rat had gastric retention and died at 1 week after GES activated.Compared with the control group,body weight,food intake,urine and stool volumes levels of the rats in experimental group decreased significantly (t =4.005,2.530,3.350,all P<0.05).Resting gastric volume was significantly lower than that in the control group [(2.93 ± 0.50) ml vs.(5.10 ± 0.53) ml,Z =2.460,P =0.014],and the intestinal juice drainage was lower than the control group [(0.18 ±0.15)ml vs.(0.44 ±0.05)ml,Z =2.513,P =0.012],while serum GLP-1 levels were similar between the two groups [(0.44 ± 0.05) ml vs.(0.18 ± 0.15) ml,Z =1.026,P =0.305],but Ghrelin was significantly higher than that in the control group [(1.65 ± 0.58) vs.(0.65 ±0.36),Z =2.380,P =0.017].Conclusion The proximal GES may lead to the change of the body weight,food intake,gastrointestinal function and motility,possibly by stimulating nerve reflex inducing gastrointestinal hormones secretion and affect gastrointestinal function.

ABSTRACT

Acute coagulopathy of trauma-shock (ACoTS) occurs in 25% of patients with severe trauma in the early phase, and the mortality of those patients is four-fold higher than patients without coagulopathy. The pathophysiology of this complicated phenomenon has been focused on in recent years. Tissue injury and hypoperfusion, activated protein C and Complements play important roles in the early phase after trauma. While the use of blood products, hypothermia, acidosis and inflammation are the main mechanism in late phase. Supplementing coagulation factors and platelets to improve ACoTS are inefficient. Only positive resuscitation from shock and improving tissue hypoperfusion have expected benefits.

ABSTRACT

<p><b>PURPOSE</b>To compare the effects and side-effects of fondaparinux sodium and low molecular weight heparin in patients with hypercoagulability accompanied with traumatic infection.</p><p><b>METHODS</b>Thirty-six patients with post-traumatic infections in our hospital intensive care center were diagnosed with hypercoagulability from February 2012 to February 2013. These patients were randomly divided into 2 groups. In group F (18 patients), the patients were treated with fondaparinux sodium, 2.5 mg, 1/d for 11 d. In group L (18 patients), the patients were treated with low molecular weight heparin, 4100 U, 1/12 h for 11 d. The incidence of deep vein thrombosis, bleeding events and multiple organ dysfunction syndrome (MODS) and mortality of two groups after anticoagulation therapy were analyzed. Fibrinogen, D-dimer level and activity of antithrombin III were measured by the coagulation analyzer.</p><p><b>RESULTS</b>The incidence of deep vein thrombosis, MODS incidence and mortality were not significantly different between the two groups. The rate of bleeding evens in group F was lower than group L (p < 0.05). Antithrombin III got an upward trend after anticoagulant therapy, in which it was higher in group F than in group L on the 5th d and 11th d (p<0.05). Fibrinogen levels were gradually increased, and there was no significant difference between two groups (p>0.05). D-dimer was significantly decreased after anticoagulant therapy for 5 d (p<0.01), and there were significant differences between two groups on the 5th d and 7th d (p<0.05). It showed no significant difference on the 11th d (p>0.05).</p><p><b>CONCLUSION</b>Fondaparinux sodium and low molecular weight heparin can effectively improve coagulopathy in patients with traumatic infection. Compared with low molecular weight heparin, fondaparinux sodium may reduce the risk of bleeding events in patients with hypercoagulability accompanied by traumatic infection.</p>

ABSTRACT

@#Objective To compare the incidence of limb dysfunction, sensory disturbance and lymphedema after different treatment methods in breast cancer patients, and evaluate the clinically relevant factors of limb dysfunction. Methods According to the different processing operation of axillary lymph nodes, 235 patients with breast cancer during 2005 to 2012 were divided into axillary lymph node dissection group in Mastoscopy (group A, n=120) and routine axillary lymph node dissection group (group B, n=115). The flexion, extension, abduction, adduction activity of the ipsilateral shoulder were compared with the contralateral, and the circumference of the up-and-down 15 cm of both upper limbs olecroanon were measured. The incidence of limb dysfunction of the patients was followed up in 6 months, 1 year and 2 years. Results There was no significant difference in limb activity and sensory disturbance between 2 groups 6 months, 1 year and 2 years after operation (P>0.05), the incidence of limb lymphedema was higher in group B than in group A (P<0.05). Radiotherapy was related with limb lymphedema in both groups (P<0.05). Conclusion Compared with the conventional axillary lymph node dissection, endoscopic axillary lymph node dissection can reduce the incidence of limb lymphedema after operation, but there was no significant difference in the limb activity and sensory disturbance between 2 groups. Postoperative radiotherapy is a risk to increase the occurrence of limb lymphedema.

ABSTRACT

Objective To observe the effects of penehydidine hydrochloride (PHC) on t acute lung injury ( ALI) . To investigate into the expression of TLR4 on peripheral monocytes, kinetics of inflammatory and anti- inflammatory mediators. To explore the mechanism of TLR4 in ALI. Method A total of 45 patients with ALI were randomly divided into PHC treatment group(experimental group, n =21) and routine treatment group (control group, n = 24) . Patients of both groups were given with the routine treatment,and patients in experimental group were given with PHC in addition (1 mg,im,ql2h) . Therapeutic effects, average length of hospital stay, ICU stay,PaO_2 and PaO_2/FiO_2 > as well as the expression of TLR4 and some cytokines were observed for 48 hours. Results Patients of both groups got better gradually after treatment. The PaO_2 and PaO_2/FiO_2 of patients of both groups progressively increased. At 6 hours, 12 hours, 24 hours and 48 hours after treatment, the PaO_2 and PaO_2/FiO_2significantly increased than 0 hour ( P < 0.05). The improvement in experimental group was obviously better than that in control group at 6 hours, 24 hours and 48 hours after treatment (P < 0.05). There were no differences in average length of hospital stay between the two groups. The ICU stay was significantly shorter in the experimental group ( P < 0.01) . The expressions of TLR4 were higher in patients of both groups than in healthy ones (P <0.01) . TLR4 decreased significantly at 24 hours and 48 hours, while it was lower in experimental group than that in the control group (P < 0.05). The higher level of TLR4in the early stage implied worse prognosis. Most of them deteriorated to ARDS stage. At 24 hours, the incidence of ARDS in experimental group was 23.8 % , and 29.17% in control group. Two patients in control group didn' t become ARDS till 48 hours. Serum IL-1, IL-8 and TNF-α level reduced atr 24 hours in both groups. The reduction of IL-8 and TNF-α in experimental group was more obvious than in control group ( P < 0.05). IL-13 increased gradually from 0 hour to 24 hours, then descended a little at 48 hours. There was no difference in IL-13 some difference between the two groups ( P > 0.05) . Conclusions PHC can improve the arterial oxygen pressure, down-regulate TLR4, restrain inflammatory factors in its signal transduction downstream. This inhibitory action is not accomplished by increase in anti-inflammatory factors,but by down-regulating TLR4. PHC can prevent the development of ALI, and can be considered to act as an effective medicine for the treatment of ALI. TLR4 plays an important role in ALT process, and it is suggested that TLR4 can be used as a prognostic factor.

ABSTRACT

Objective To investigate the factors influencing the incidence of acute pancreatitis (AP) in patients with organophosphorus poisoning and explore the effectiveness of measures for its prevention and treatment. Methods Clinical data of 50 patients with organophosphorus poisoning were reviewed retrospectively in our center between January 2001 and December 2006. Results The incidence of AP in patients with organophosphorus poisoning was 30% (15/50), and 14 patients suffered from MAP, while one patient occurred SAP. 13 of 15 AP patients underwent gastric lavage with cold normal saline; gastric tube was placed in 14 patients; toxic doses over 50 ml were observed in 10 patients; atropine overdose were observed in 11 patients. There were 35 cases of organophosphorus poisoning alone, and 2 of them underwent gastric lavage with cold normal saline; gastric tube was not placed in 1 patient; toxic doses over 50 ml were not observed in all the patients. The toxic dose, water temperature for gastric lavage, gastric tube placement, duration from poisoning to treatment between the two groups were significantly different (P<0.01). All the patients with organophosphorus poisoning alone survived, while in these 15 patients with AP, 14 patients were cured, 1 patient died. Conclusions Organophosphorus poisoning can induce AP and development of AP was possibly related to organophosphorus poisoning and improper treatment.
