Objective To evaluate the role of differentially expressed genes in human prostate carcinoma initiation and progression. Methods cDNA microarray chips which consist of a set of 4366 human genes were used to investigate the gene expression pattern of samples from human prostate cancer and normal prostate tissues. Results Of 4366 genes,287 genes differentially expressed in prostate carcinoma and normal prostate tissues were screened out,including 165 unknown genes and 122 known genes. Among the 122 known genes we further identified 20 up-regulated and 36 down-regulated genes. Conclusions Our results suggest that significantly differential expression of genes may be associated with the pathogenesis and progression of the prostate cancer.

OBJECTIVE:To study the effects of soluble cluster differentiation 14 (sCD14) on serum pro-and anti-inflammatory cytokines in mice with serious scald endotoxemia. METHODS: A total of 60 healthy Kunming mice were randomly assigned to sCD14 (5 mg?kg-1) group, treatment control group (normal saline) and normal control group (normal saline). The first two groups were established into scald model (scald of 30% body surface area, Ⅲ degree scald) followed by intravenous injection of the corresponding drugs in every 12 h via vena caudalis for 3 consecutive days. On day 4, the model mice were sacrificed to obtain the serum sample for the detection of levels of proinflammatory cytokines (TNF?, IL-6) and anti-inflammatory cytokines (IL-4 and IL-10). RESULTS: In sCD14 treatment group, serum levels of TNF?, IL-6 were significantly lower than in treatment control group (P

OBJECTIVE:To evaluate the effects of the individualized treatment with GIK(Glucose-insulin-potassium)polarized solution on the discharged surgical patients with hyperglycemia.METHODS:2 287 surgical patients with hyperglycemia(including 125 who had diabetes before hospitalization)receiving individualized treatment with GIK(Glucose-insulin-potassium)polarized solution and who had been discharged from hospital for 1 year were surveyed by questionnaire to collect the data of adverse drug reactions of the polarized solution.RESULTS:None of the patients had secondary diabetes mellitus,hypertension,hypoglycemia or psychological dependence on insulin;0.6% worried about the sequela of GIP;98.5% of the patients who had diabetes prior to hospitalization and have been taking insulin after been discharged from hospital agreed that the symptom of their diabetes was greatly lessened by insulin;100.0% of the patients who had diabetes prior to hospitalization and received no insulin after been discharged from hospital agreed that taking large dose of insulin during hospitalization had no effect on the symptom of their diabetes or hypertension;99.3% of patients received supplemental nutrition of polarized solution;96.9% given hyperglycemia control;38.3% received antiinflammation therapy,5.5% received protective therapy for ? cell function.CONCLUSION:Individual treatment with GIK on the surgical glycemia patients is a safe remedy without sequela.But a few of surgical glycemia patients are afraid of the ADR of the polarized solution,suggesting the importance of publicizing the use of GIK.

Objective Transesophageal Doppler monitoring ( TDM) has been widely applied to fluid therapy in some major op-erations but rarely used in aortic valve replacement.The purpose of this study was to assess the value of TDM in fluid therapy, vasoactive drugs use, and left ventricular function in patients undergoing aorta valve replacement after cardiopulmonary bypass. Methods This study included 40 patients undergoing aotic valve replacement after cardiopulmonary bypass in Anhui Provincial Hospital from March 2014 to June 2015, which were randomly assigned to a TDM and a control group of equal number.TDM was used for the guidance of fluid infu-sion and vasoactive drug administration for the patients in the former group, while central venous pressure, mean arterial pressure, and heart rate were employed for those in the latter.The fluid volume infused, urine volume, blood loss, hemodynamics, arterial blood lac-tate, and outcomes were compared between the two groups. Results Compared with the control, the TDM group showed significantly increases in the colloidal fluid volume ([303 ±60] vs [373 ±65]mL, P<0.05), crystal fluid volume ([533 ±87] vs [596 ±83]mL, P<0.05), and urine volume ([274 ±95] vs [338 ±84]mL, P<0.05), but remarkable decreases in the red blood cell count, blood plasma vol-ume, postoperative extubation time, doses of dopamine and dobu-tamine, and length of hospital stay (all P<0.05).The hemodynamics were more stable and arterial blood lactate was lower in the TDM group than in the control (P<0.05). Conclusio n Transesophageal Doppler monitoring can timely and exactly manifest the hemodynamic changes and left ventricular function of the patient undergoing aotic valve replacement and provide precise guidance for fluid therapy and vasoactive drug administration.

A method of derivatization at injection port following three phase hollow fiber microextraction with tetramethylammonium hydroxide (TMAH) as a dual-function reagent, for the simultaneous determination of salicylic acid, p-hydroxybenzoic acid, cinnamic acid, vanillic acid, p-coumaric acid and ferulic acid in beers by gas chromatography was developed. Phenolic acids were extracted from aqueous samples to a thin layer of organic solvent ( hexyl acetate) phase impregnated into the pores of the hollow fiber wall, and then back extracted to an acceptor solution (TMAH) located inside the lumen of the hollow fiber. Upon injection, the phenolic acids were derivatized to their methyl esters in the GC injection port. Several parameters related to the derivatization and extraction efficiency were optimized. The optimized conditions were as follows: hexyl acetate was used as the extraction solvent, an aqueous solution of TMAH (5% W/ V) was used as the derivatization reagent and acceptor phase, the pH value of donor phase was 2. 0, the concentrations of NaCl was 25% W/ V, the stirring rate was 500 r/ min, the extraction time was 40 min. Under the optimal conditions, the linear range of phenolic acids was 0. 50 -15. 00 mg / L, the limits of detection were 0. 05 -0. 18 mg / L. The proposed method was applied to the determination of the phenolic acids in beers. Vanillic acid, p-coumaric acid and ferulic acid were found in the beer samples, others were not detected. The spiked average recoveries were 90. 1% -106. 8% and RSD% was less than 5. 9% (n =3). The method is suitable for the determination of phenolic acids in beers.

Objective This study is to investigate the protective effect of creatine phosphate so-dium on circulatory function in unilateral total knee replacement surgery using bone cement implanta-tion.Methods Forty patients undergoing unilateral total knee replacement surgery with bone cement were randomly assigned into 2 groups:test group (group CP,n=20)and control group (group NS, n=20).The easophageal doppler ultrasound probe was placed at the level of the third rib transorally after induction in each patient.In group CP,creatine phosphate sodium (2 g in 100 ml normal saline) was infused (within 30 min)at 30 min before the operation,as well as normal saline 100 ml in group NS.SBP,DBP,HR,SpO2 ,PET CO2 and BIS were monitored and recorded before (T0 )and 1 (T1 ),3 (T2 ),5 (T3 ),10 (T4 )min after insertion of bone cement.Cardiac output (CO),stroke volume (SV)and left ventricular end-diastolic volume (LVEDV)were simultaneously monitored and recorded with esophageal doppler ultrasound.WhileⅡ-lead electrocardiogram were recorded to monitor ven-tricular arrhythmia perioperatively.Results SBP,DBP and HR decreased at T2 and T3 in group NS, and were lower than those in group CP (P <0.05 );Meanwhile,compared with group CP,CO and SV were significantly lower,while LVEDV was significantly higher in group NS (P <0.05 ).Com-pared with T0 ,CO and SV decreased and LVEDV increased at T2 and T3 in group NS (P <0.05 ). After insertion of bone cement,the incidence of arrhythmia in group CP was obviously lower than that in group NS (P < 0.05 ).Conclusion Pretreatment with creatine phosphate sodium can effectively prevent the incidence of bone cement implantation syndrome (BCIS)by stabilizing hemodynamic in elderly patients undergoing total knee replacement with bone cement.

Objective To investigate the efficiency and safety of agkistrodon hemocoagulase on coagulation function in pa?tients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB). Methods In this prospective,randomized controlled trial,80 eligible patients accepted valve replacement were assigned to control group (n=20) and agkistrodon hemoco?agulase groups (H1, H2, H3) according to the different timing of administration. Twenty patients were given treatment 20 minutes before anesthesia induction (H1 group), 20 patients were given treatment 20 minutes after CBP (H2 group) and 20 patients were given treatment after CBP (H3 group). Coagulation parameters including prothrombin time (PT), activated partial thromboplas?tin time (APTT), thrombin time (TT), fibrinogen (Fib) and platelet (PLT) were detected 20 minutes before surgery (T0), immedi?ately after surgery (T1) and 24 hours after surgery(T2). Data of 24-h postoperative drainage of mediastinal and pericardial, dura?tion of mechanical ventilation, stay time of intensive care unit (ICU), the actual days of hospitalization and hospital costs were recorded. The clinical parameters were also recorded including blood transfusion after surgery, secondary thoracotomy, aller?gies, liver and kidney dysfunction, deep vein thrombosis and neuropsychiatric symptoms. Results Compared with control group, values of PT, APTT and TT at T1 and T2 were significantly lower in H1, H2 and H3 groups (P<0.05). Compared with T0, values of PT, APTT and TT at T1 and T2 were significantly higher in all groups of patients (P<0.05). Values of PT and TT at T1 and T2 were significantly decreased in H3 group than those of H1 group (P<0.05). The pericardial and mediastinal drainage, the duration of ventilation support within 24-h after surgery were significantly lower in H1, H2 and H3 groups than those of control group (P<0.05). There was no significant difference in the incidence of adverse events between groups. Conclusion Agkis?trodon hemocoagulase is safe and effective in patients undergoing cardiac valve replacement with cardiopulmonary bypass.

Objective To investigate the therapeutic effects of modified Xiaoyao Powder combined with abdominal needling for conducting fire back to its source for the treatment of swallowing dysfunction in Parkinson's disease, and to explore a more effective therapy for swallowing dysfunction in Parkinson's disease. Methods Forty-two Parkinson's disease patients suffering from swallowing dysfunction were divided into treatment group and control group, 21 cases in each group. The patients in both groups received routine swallowing function training. In addition to the training, the treatment group was treated with modified Xiaoyao Powder combined with abdominal needling for conducting fire back to its source, and the control group was given conventional western medicine of Domperidone and Levodopa Benserazide Hydrochloride. After treatment for 3 weeks, we compared the dysphagia scores and effective rate of the two groups. Results (1) All of the patients in the treatment group completed the trial, but 2 cases of the control group dropped out. Therefore, a total of 40 cases completed the trial. (2) The dysphagia scores of the two groups were much improved after treatment (P<0.01 compared with those before treatment) , and the improvement of the treatment group was superior to that of the control group (P < 0.05). (3) After treatment for 3 weeks, the total effective rate of the treatment group was 95.24% and that of the control group was 52 . 63%, and the difference was statistically significant between the two groups(P<0.01).(4) Gastrointestinal reaction occurred in 3 cases(one from the treatment group and 2 from the control group) , but there were no other side effects found in both groups. Conclusion Modified Xiaoyao Powder combined with abdominal needling for conducting fire back to its source is more effective for the treatment of swallowing dysfunction in Parkinson's disease than routine western medicine treatment.

Objective To investigate the effects of methylprednisolone on lung function and inflammation during one-lung ventilation in patients undergoing pulmonary lobectomy.Methods Sixty patients (46 males, 10 females, aged 18-60 years, ASA grade Ⅰ or Ⅱ) scheduled for pulmonary lobectomy were randomly divided into two groups (n=30 each) using a random number table: the control group (group C) and the methylprednisolone group (group M).Patients in group M were treated with methylprednisolone before induction of anesthesia within 30 min, whereas patients in group G received equal volume of normal saline at the same time.The heart rate (HR), mean arterial pressure (MAP), peak airway pressure (Ppeak), plateau airway pressure (Pplat), and dynamic lung compliance (Cdyn) were recorded at the momment before OLV (T1), 30 min after OLV (T2), 1 h after OLV (T3), 10 min after resuming two-lung ventilation (T4) and the end of the surgery (T5).The arterial blood gas analysis were performed at the above time points in order to determined the oxygen partial pressure (PaO2) and carbon dioxide partial pressure (PaCO2), then the oxygenation index (OI), alveolar to arterial difference of oxygen tension (A-aDO2) and respiratory index (RI) of each patient was evaluated.The concentration of serum TNF-α, IL-6 and IL-10 were determined by ELISA at T0, T4, 6 h (T5) and 24 h (T6) after surgery using venous blood samples.The incidence of pulmonary complications at 72 h after operation were also recorded.Results Compared with T0, the MAP and Cdyn was decreased, whereas the Ppeak and Pplat was increased significantly in both group at T1, T2 (P＜0.05), the OI was decreased and the A-aDO2, RI was increased significantly at T1-T4 (P＜0.05), and the concentration of serum TNF-α, IL-6 and IL-10 at T4-T6 was increased significantly in both group (P＜0.05).Compared with group C, the Cdyn was increased, the Ppeak and Pplat were decreased significantly in group G at T1, T2 (P＜0.05), the concentration of serum TNF-α and IL-6 were decreased, and IL-10 was increased significantly in group G at T4-T6 (P＜0.05).The incidence of postoperative pulmonary complications had no statistically signifcant differences between the two groups.Conclusion Methylprednisolone can significantly improve the pneumodynamics and lung compliance, alleviates the inflammatory responses, but have no significant effect on intrapulmonary oxygenation and gas exchange during one-lung ventilationin patients undergoing pulmonary lobectomy.

Objective To investigate the effect of dexmedetomidine on the cerebral injury in patients undergoing cardiac valve replacement under cardiopulmonary bypass (CPB).Methods Forty ASA Ⅱ or Ⅲ patients of both sexes,aged 43-64 yr,scheduled for elective cardiac valve replacement,were randomly divided into 2 groups (n =20 each):control group (group C) and dexmedetomidine group (group D).Dexmedetomidine 0.6 μg/kg was injected intravenously over 15 min before induction of anesthesia,followed by infusion at 0.2μg· kg-1 · h-1 until the end of operation in group D.While the equal volume of normal saline was given in group C.Blood samples were obtained from the radial artery and jugular bulb for blood gas analysis before CPB,immediatelv after declamping of the ascending aorta,at the end of CPB and at 6 h after operation (T1-4).The arteriovenous blood O2 difference (Da-jvO2) and cerebral O2 extraction rate (CERO2) were calculated.The plasma concentrations of S-100β and neuron-specific enolase (NSE) in the blood samples obtained from the jugular bulb were measured at T1-4 and 24 h after operation.Results Compared with group C,the jugular venous oxygen saturation was significantly increased and Da-jvO2 and CERO were decreased at T2,3,and the plasma concentrations of S100β and NSE were decreased at T2-4 in group D (P ＜ 0.05).Conclusion Dexmedetomidine can decrease the cerebral O2 metabolic rate and reduce the cerebral injury in patients undergoing cardiac valve replacement under CPB.
