Acute kidney injury(AKI) is a clinical critical syndrome caused by a variety reason,sepsis is the leading cause and independently associated with mortality in critical patients.Fluid resuscitation is one of the most important treatment of spesis and AKI.Fluid overload has been shown to be associated with worse outcomes in critically ill patients.Different liquid treatment should be adopted in different stages.To carry out dynamic,noninvasive hemodynamic monitoring is the best way to critical patients with AKI liquid management.

Objective To report the clinical manifestation and gene mutation of congenital insensitivity to pain with anhidrosis (CIPA) in two patients from one family. Methods The data of clinical manifestation, laboratory examination, and family history of two patients were collected. The peripheral blood of patients and their parents were collected. Neurotrophic tyrosine kinase receptor type 1 (NTRK 1 ) gene was detected directly by Sanger method, the pathogenicity of the mutation in the gene was analyzed by bioinformatics. Results Both of patients were female and mainly suffered with reduplicated non-infectious fever, anhidrosis, insensitive to pain, and mental retardation. The proband had fracture many times after minor injury. The ninth exon of NTRK 1 genes in the proband and her younger sister were found to have heterozygous mutations, c. 851-33 T>A, as previously reported. Meanwhile, there was also found a new mutation, c. 1711 G>A (p.G 571 S), in thirteenth exon of NTRK 1 genes in these two patients. It was predicted to be a harmful mutation by bioinformatics and the mutation site is conservative. Their father and mother were found carrying the c. 851-33 T>A and c. 1711 G>A mutations respectively. Conclusion Both patients had typical clinical manifestations. And the newly discovered p.G 571 S mutation expands the mutation spectrum of NTRK 1 gene.

Objective To study the value of plasma level of matrix metalloproteinase-9 (MMP-9) for the early diagno-sis of Kawasaki disease. Methods The difference in MMP-9 level was studied by retrospective nested case-control method between children with early Kawasaki disease, Henoch-Sch?nlein purpura (HSP) or respiratory infection, and healthy control children. The associations of MMP-9 with serum procalcitonin, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were also analyzed. The cutoff-value, sensitivity and speciifcity of MMP-9, ESR and CRP in diagnosis of Kawasaki disease were studied by ROC curve. The areas under ROC curves were compared among different diagnostic markers to deter-mine their signiifcances in diagnosis of Kawasaki disease. Results The plasma level of MMP-9 was increased in early phase of Kawasaki disease, and higher than that in children with HSP or respiratory infections and in healthy controls (P<0.05). If MMP-9, ESR and CRP cutoff value were set to be 90.23 ng/ml, 56.5 mm/h and 27.55 mg/L, the sensitivity, speciifcity and area under ROC curve was 83.3%, 86.4%and 0.904, 95.8%, 66.1%and 0.807, 83.3%, 74.6%and 0.789 respectively. The diagnostic performance of MMP-9 for Kawasaki disease was better than that of ESR and CRP. Conclusions The plasma level of MMP-9 is increased in the early stage of Kawasaki disease. The sensitivity and speciifcity of MMP-9 in diagnosis of Kawasaki disease are highest if cutoff value is set to be 90.23 ng/ml.

Objective To explore the clinical-pathological characteristics, treatment and prognosis of eosinophilic gastro-enteritis in children. Methods The data of clinical manifestation, laboratory examination, endoscopy, biopsy, management and prognosis from 2 pediatric patients with eosinophilic gastroenteritis were retrospectively analyzed. Related articles were reviewed. Results The age of two patients was 13 and 14 years old. Case 1 was male and had an onset with acute pancreatitis. Case 2 was female with a history of food allergy and had an onset with unexplained ascites. Both patients presented with signiifcantly increased peripheral eosinophil count (45.9%-64.8%) and serum IgE (246-393 IU/ml). Bone marrow cytology showed increased proportion of eosinophils in both patients. Gastroscopy was performed in case 1 while gastroscopy and colonoscopy endoscopy were performed in Case 2 and the results indicated eosinophilic inifltration in duodenum. Duodenal mucosa biopsy showed eosinophilic inifltration in case 1 while gastrointestinal pathology biopsy showed multiple mucosal eosinophil inifltration in case 2. After the therapy of food avoidance, steroid and anti-allergic drugs, both patients had complete remission 1 week later. Meanwhile the peripheral eosinophil count was decreased to normal. Case 1 was followed up for 24 months, and case 2 was followed up for 2 months. Both patients showed no evidence of relapse. Conclusions The clinical manifestation and endoscopic examination of eosinophilic gastroenteritis in children are protean and lack of speciifcity. Unexplained gastrointestinal symptoms accompanied with eosinophilia may suggest the possibility of eosinophilic gastroenteritis. Eosinophilic inifltration in ascites and gastrointestinal mucosa strongly indicate the di-agnosis of eosinophilic gastroenteritis. After exclusion of other possible diseases, the deifnite diagnosis can be made.

Objective:To investigate the effects of lipopolysaccharide (LPS)on the acute lung injury (ALI)and expressions of aquaporin 1 (AQP1)and aquaporin 5 (AQP5)in lung tissue of the rats. Methods:Forty-eight SPF grade male Wistar rats were randomly divided into control group and LPS group (n=24).The rats in LPS group were intravenously injected with LPS to induce ALI models,and the rats in control group were injected with saline. The rats were sacrificed at 2,6,12 and 24 h,and the samples were collected after the successful modeling.The pathological changes of lung tissue were observed with HE staining;the lung wet/dry weight (W/D)ratio and lung permeability index were detected;ELISA was used to detect the levels of TNF-αand MIP-1α.The expression levels of AQP1 and AQP5 protein and mRNA were measured by Western blotting,immunohistochemistry and Real-Time PCR methods. Results:Compared with control group, the TNF-α and MIP-1α levels in LPS group were significantly elevated at 2,6 and 12 h (P<0.05),and at 24 h they were gradually reduced to the normal level. The HE staining results showed the alveolar and interstitial edema at 2 h after LPS injection,obviously in 12 h. The lung W/D ratios and pulmonary permeability indexes at different time points in LPS group were significantly higher than those in control group (P<0.05),and they reached the peak at 12 h.The expression levels of AQP1 and AQP5 mRNA and protein in lung tissue of the rats at different time points in LPS group were significantly lower than those in control group (P<0.01 ). Conclusion:LPS can induce ALI in the rats and down-regulate the expressions of AQP1 and AQP5;LPS is involved in the formation of pulmonary edema.

Objective To explore the effect of galanin ( GAL) on locus coeruleus ( LC) neurons from neonatal rat and mechanism with its receptor GalR and potassium channel.Methods Brain slices from neonatal rats were prepared and the resting membrane potential and spontaneous action potential of LC neurons were recorded with whole cell patch-clamp configuration.GAL, AR-M1896 and potassium channel blockers were bath applied with different concentration.Results Bath application GAL induced hyperpolarization and inhibited firing rate of LC neurons.However, AR-M1896 ( a selective GalR2 agonist) did not induce significant effect on LC neurons, only at very high concentration(1μM) it induced slight hyperpolarization and reduced firing rate.The inhibitory effect of GAL was partially blocked by TEA ( an antagonist of voltage-dependent potassium channel) and significantly blocked by BaCl2(an antagonist of inward-rectifying potassium channels), while other potassium channels blockers such as Glybenclamide(ATP-sensitive potassium channel blocker),Charybdotoxin(large-conductance Ca2 +-activated K + channels blocker),Apamin(small-conductance Ca2 +-activated K +channels blocker) failed to block it.Conclusion GAL inhibits LC neurons from neonatal rats, mainly through GalR1.TEA-sensitive potassium channels and inward-rectifying potassium channels, but not ATP-sensitive potassium channel and calcium-activated potassium channel, are involved in this inhibition.

Objective To investigate the therapeutic efficacy of castration with 125I brachtherapy in middle and late stage prostate cancer. Methods Sixty-six patients with prostate cancer from 2004 to 2009 were analyzed, 40 were at clinical stage C and 26 were at clinical stage D, 42 had a pathologic grade G2 and 24 had a pathologic grade G3. The first endocrinal therapy used was total androgen blockade (chemical castration and anti-androgen drugs). The therapeutic time was three months before bilateral orchidectomy and brachtherapy. A 3D radiotherapy planning system was used for brachtherapy with transrectal ultrasound-guided radioactive 125I seed uniform implantation. Follow-up endocrinal therapy was decided according to a monthly check of serum PSA (prostate specific antigen) levels. After six months, serum PSA, IPSS and volume of the prostate before and after treatment were compared. Results The operations were completed successfully in all cases. The mean number of 125I seeds implanted was 55. The mean follow-up was 10 to 62 months, with an average of 49 months. Serum PSA, IPSS and the volume of the prostate was reduced significantly six months after operation (P<0.05). Conclusions Castration with 125I brachtherapy is an effective approach in combination therapy for treating middle and late stage prostate cancer.
