Objective To explore the risk factors causing tetany in patients with hyperventilation syndrome. Meth?ods A total of 103 patients with hyperventilation syndrome treated in our hospital were included in this study. According to whether there was tetany, patients were divided into tetany group and non-tetany group. Values of gender, age, electrolyte, pH and p(CO2) were analysed between two groups. The factors of P<0.1 were engaged in binary Logistic regression. Logistic regression (Forward Wald) was used to analyze the risk factors of tetany in patients with hyperventilation syndrome. Re?sults In 103 patients there were 70 patients with tetany (68%), 33 patients without tetany(32%). The serum K+, serum phos?phorus and p(CO2) values were significantly lower in tetany group than those of non-tetany group (P<0.01), while the pH value was significantly higher in tetany group than those of non-tetany group (P<0.01). There were no significant differences in gen?der, age, serum Na+, serum Cl-, serum calcium (bound calcium and ionized calcium), ionized calcium and serum Mg2+levels be?tween two groups (P>0.05). It was revealed that the younger age, the lower level of the serum K+, serum phosphorus and p(CO2) were the risk factors of tetany through binary Logistic regression analysis. Conclusion The risk factors of tetany in patients with hyperventilation syndrome include younger age, lower level of serum K+and serum phosphorus and reduced p(CO2).

Objective To investigate the relationship of T peak-T end (Tp-Te) interval and Tp-Te interval disper-sion (Tp-Ted) in different periods of myocardial ischemia in patients with acute myocardial infarction (AMI), and to assess the clinical significance of Tp-Te and Tp-Ted for prediction of the ventricular arrhythmia (VA). Methods A total of 80 pa-tients with AMI were enrolled in the study. The sizes and changes of Tp-Te and Tp-Ted were observed during the acute phase and recovery phase in patients. The differences of Tp-Te and Tp-Ted were compared between ventricular tachycardia group (A group), ventricular premature beats group (B group) and non- ventricular arrhythmia group (C group). Results The values of Tp-Te and Tp-Ted were obviously longer in acute period [(125.22±17.70) ms and (54.76±13.26) ms] than those in recovery period[ (113.84±17.37) ms and (42.06±13.95)ms] (P<0.01). The values of Tp-Te and Tp-Ted were signifi-cantly longer in A group[ (134.82±19.56) ms and (62.00±15.19) ms] than those in B [(122.94±15.09) ms and (54.09±10.56) ms ]and C group [(110.09±15.21) ms and (45.27±9.85) ms]. The values were higher in B group than those of C group. Con-clusion The Tp-Te interval and Tp-Ted prolongated in acute phase than those of recovery phase in patients with AMI. Tp-Te interval and Tp-Ted can be used as an important index to predict VA in patients with AMI.

Objective To investigate the effect of early low-glucocorticoid on hemodynamics and prognosis in the patients with septic shock.Methods Sixty patients with septic shock failing in active fluid resuscitation and vasoactive drugs in our hospital from June 2013 to August 2015 were selected and divided into the control group,early-hormone group and late-hormone group.MAP,HR,PO2/FIO2 and serum lactic acid levels were monitored in all selected patients before treatment and at 12,24,48 h after treatment.Apache Ⅱ,SOFA scores were assessed before treatment and on 1,3,7 d after treatment.The ventilation time,ICU stay time,hospital stay time and intravenous use time of vasoactive agents(VDNT) were recorded.Results The Apache Ⅱ scores and SOFA scores on 3,7 d after treatment in the early-hormone group were significantly decreased compared with the late-hormone group and control group (P＜0.05).MAP and HR at 24,48 h after treatment in the early-hormone group were significantly improved compared with the late-hormone group and control group (P＜0.05).The level of serum lactic acid at 12,24 h after treatment in the early-hormone group and late-hormone group were obviously lower than that in the control group,the levels of serum lactic acid at 12,24 h after treatment in the early-hormone group were obviously lower than those in the late-hormone group (P＜ 0.05).PO2/FIO2 at 12 h after treatment in the early-hormone group and late-hormone group were obviously better than that in the control group,and PO2/FIO2 at 12 h after treatment in the early-hormone group was obviously better than that in the late-hormone group(P＜0.05).The ventilation time,ICU stay time,hospital stay time and VDUT in the early-hormone group were significantly shortened compared with the late-hormone group and control group.The ventilation times,ICU stay time and VDUT in the latehormone group were significantly shortened compared with the control group (P＜0.05).Conclusion Early using low-dose glucocorticoid may restore hemodynamics more quickly,protects the organ function and improves the prognosis in the patients with septic shock.

Objective To investigate the influence of Let-7f regulation on MMP-11 in migration and in-vasion of pancreatic cancer. Methods RT-qPCR was performed to assay the expression of Let7 and MMP-11 ex-pression in pancreatic cancer cells and normal pancreatic cells. Let-7f mimic and inhibitor were transfected to PANC-1 and Bx-PC3, respectively. The influence of Let-7f expression on migration and invasion of pancreatic cancer cells was analyzed by transwell. The influence of Let-7f intervention on MMP-11 expression was observed by RT-qPCR. Results Let-7f expression decreased in PANC-1 and Bx-PC3, compared to HPDE6c7, while MMP-11 expression up-regulated in PANC-1 and Bx-PC3 , compared to HPDE6c7 cells. Let-7f overexpression in-hibited the expression of MMP-11. Up-regulated Let-7f could significantly inhibit migration and invasion of PANC-1 and Bx-PC3 and Let-7f inhibitor enhanced MMP-11 expression. However , down-expression of Let-7f could not significantly promote migration and invasion abilities of PANC-1 and Bx-PC3cells. Conclusions Let-7f may affect migration and invasion by regulating MMP-11 expression in pancreatic cancer , suggesting that Let-7f might be a potential target for gene therapy in human pancreatic cancer.

Objective To evaluate the effectiveness of thoracic electrical bioimpedance(TEB)in monitoring the cardiac function of peritoneal dialysis patients.Methods One hundred and one patients with continuous ambulatory peritoneal dialysis (CAPD) and 30 healthy persons (control group)were included in the study.Thoracic electrical bioimpedance (TEB) noninvasive hcmodynamic monitoring and echocardiography were taken to analyze the correlation between indexes.Results Echocardiography showed that left atrial diameter (LAD),left ventricular end diastolic diameter (LVDd),left ventricular end systolic diameter (LVDs),interventricular septal thickness （IVST),interventricular septal thickness (PAP),left ventricle weight index (LVMI) of CAPD group were higher than that of the control group (all P ＜ 0.05),early and late wave of mitral valve flow (E/A) of CAPD group was lower than that of control group (P ＜ 0.05).TEB monitoring showed that cardiac output (CO),stroke volume (SV),acceleration index (ACI),ejection fraction (EF),velocity index (Ⅵ) of CAPD group were significantly lower than that of control group (all P ＜ 0.01),systolic time ratio (STR),SVR,TFC of CAPD group were significantly higher than that of control group (P ＜ 0.01).Correlation analysis show that left ventricular ejection fraction (LVEF) was negatively correlated with BNP (r =-0.467,P ＜ 0.01),LVMI was positively correlated with BNP (r=0.416,P ＜ 0.01),PEP,STR and TFC were positively correlated with BNP (r =0.404,P ＜ 0.01; r =0.572,P ＜ 0.01; r=0.471,P ＜ 0.01),EF was negatively correlated with BNP (r =-0.664,P ＜ 0.01).Correlation analysis between echocardiogaphy and TEB monitoring index showed there was significant correlation between EF and LVEF (r =0.451,P ＜ 0.01),SVR and TFC were positively correlated with LVMI (r =0.232,P ＜ 0.05; r =0.284,P ＜ 0.05),SV was positively correlated with E/A (r =0.285,P ＜ 0.05),pre-ejection period (PEP) and STR were negatively correlated with LVEF (r =-0.389,P ＜ 0.01; r =-0.446,P ＜ 0.01),TFC was positively correlated with LAD (r=0.279,P ＜ 0.05).Conclusion TEB monitoring can accurately evaluate the cardiac function with the advantage of dynamic monitoring and simple operation.It can partly replace the echocardiography test.

Objective To investigate the role of metastatic lymph node ratio (MLR) in the evaluation of prognosis of patients with gastric cancer (GC) at different lymph node numbers examined.Methods Clinical data were reviewed retrospectively in a total 535 patients who underwent surgery for GC.Spearman correlation analysis between MLR or number of metastatic lymph nodes (N) and examined lymph node numbers,Kaplan-Meier method was used for comparison survival rates of N stage and MLR stage.A receiver operating characteristic (ROC) curve was used to evaluate the role of N stage and MLR stage in the prognosis of GC patients.Results Metastatic lymph node ratio and number of metastatic lymph nodes correlated with the examined lymph node numbers (r =0.146,r =0.378,P ＜ 0.01,P ＜ 0.001).The 5 year survival rate of MLR0,MLR1,MLR2 and MLR3 patients were 57.5％,69.9％,40.0％ and 21.7％ respectively when examined lymph node numbers ＜ 6 (P ＜ 0.01).The 5-YSR of MLR0,MLR1,MLR2 and MLR3 patients were 86.8％,59.2％,35.8％ and 39.2％ respectively when between 6-10 (P ＜0.001) and the 5-YSR of MLR0,MLR1,MLR2 and MLR3 patients were 88.7％,62.5％,0 and 17.7％ respectively when they ＞ 10(P ＜0.001).AUC of MLR staging was 0.68 ±0.05 when the numbers ＜ 6 (P ＜ 0.001).AUC of MLR staging was 0.72 ± 0.04 at numbers 6-10 (P ＜ 0.001).AUC of MLR staging was 0.79 ± 0.03 when numbers ＞ 10 (P ＜ 0.001).Conclusions MLR was less influenced by lymph node number examined than N.MLR stage has potential superiority to that the N stage in assessing prognosis of GC patients,especially for patients with more than 6 lymph nodes examined.

Objective To review the diagnosis and treatment of squamous cell carcinoma of renal pelvis. Methods The clinical data from October 1991 to May 2009 of eight cases of squamous cell carcinoma of renal pelvis were reviewed and analyzed retrospectively. The symptoms of the patients were hematuria (eight cases), pain (seven cases) and abdominal mass (one case). All patients underwent B-ultrasound and IVU examination and four cases underwent CT scan. Three cases were diagnosed as having a tumor before surgery. Five cases were diagnosed as renal calculus, two of the five cases were diagnosed by intraoperative frozen section. Radical nephroureterectomy were performed in four cases, nephrectomy in three cases and palliative resection in one case. Results Histological classification revealed that six cases were moderately differentiated, one case was well differentiated and one case was poorly differentiated. Two cases had stage pT1/pT2 and six cases had stage pT3/pT4. 2 cases had regional lymph nodes metastasis. Seven cases were followed-up. All patients died of tumor recurrence or metastasis. The median tumor specific survive time was six months (range from two months to 42 months). Conclusions Squamous cell carcinoma of renal pelvis is often occurs concurrently with urolithiasis which could lead to difficulty in diagnose before operation. As the most of the patients were diagnosed with advanced stage disease, squamous cell carcinoma of renal pelvis tended to early recurrence and metastasis and the prognosis was very poor.

Objective Detecting of spermatozoal total RNAs by laboratory on chip gel electrophoresis so that it could provide better total RNAs for the sequent experiments, and spur the development of spermatozoal molecular biology. Methods Sperms of healthy adults were collected and then total RNAs were extracted by RNeasy mini kit(QIAGEN), detection and quality control were performed by loboratory on chip gel electrophoresis system. Meantime, the control RNAs were extracted from lymphocytes. Results It was found that there were a plenty of genes expressed in healthy sperms. Electrophoretic graphs showed that the total RNAs of spermatozoal had 2 bands which went ahead a little comparing to the normal somatic cells. The former peak appeared keenness, and the latter was broad and showed like a reversed U. The ratio of them was largely more than 2, no extra peaks were found in electrophoretic graph. Conclusion A simple,intuitionistic method to detect and control the quality of the healthy adults' spermatozoal total RNAs had been successfully constructed by using laboratory on chip gel electrophorosis.
