Objective To discuss the incidence trends of hyperuricemia in people of different TCM constitutional types by analyzing the constitutional types of patients with hyperuricemia,and to lay a foundation for follow-up study in preventive and therapeutic measures for hyperuricemia.Methods 518 healthy people and 525 people of hyperuricemia were included in our research by identifying their TCM constitutional types by the self testing table of constitutional classification and determination of TCM promulgated by China Association of Chinese Medicine.Hyperuricemia's high-risk constitutional types were analyzed.Results People of dampness-heat constitution (24.57％),phlegm-dampness constitution (22.86％) and static-blood constitution (11.05％) were top 3 groups in occurrence rate of hyperuricemia,the risk ofhyperuricemia in these three groups above were significantly higher than the other constitutional types.On the contrary,the risk of hyperuricemia in the group of the mildly constitution (8.57％) and the group of qi-asthenia constitution (6.29％)were significantly lower than the other groups.Conclusion People of dampness-heat constitution,phlegm-dampness constitution and static-blood constitution were high risk groups of hyperuricemia,which deserved our attention in research of preventive and therapeutic measures for hyperuricemia.

Objective To evaluate the efficacy of MRI-detected extramural venous invasion (mrEMVI) in predicting tumor responses to preoperative chemoradiatiotherapy (pre-CRT) in patients with locally advanced rectal cancer (LARC).Methods The clinicopathological data,tumor response and mrEMVI information of 47 LARC from February 2013 to December 2014 were retrospectively collected.mrEMVI was given 0-4 score according to the degree,3-4 score were defined as mrEMVI positive;patients with mrEMVI positive were divided into three subgroups according to vascular size (large,middle and small).Association between different mrEMVI subgroup and tumor response was analyzed using Fisher exact test.Result 26 patients were mrEMVI positive.18 and 8 patients scored 3 and 4 for mrEMVI positive,respectively;16,6 and 4 patients were small,middle and larger vessels of mrEMVI positive,respectively.Patients with mrEMVI positive had less TRG 0-1 than mrEMVI negative (P =0.019).Scored 4 and larger vessel of mrEMVI positive had less TRG 0-1 than mrEMVI negative (P =0.038 and 0.017).Conclusions mrEMVI positive score 4 or larger vessel predict poor tumor response to pre-CRT in patients of locally advanced rectal cancer.

Objective To assess the early prognosis of 117 patients after carduopulmonary resuscitation (CPR) in ICU by using the markers of inflammation,Glasgow Coma Scale (GCS) and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores.Methods A total of 117 CPR patients admitted between 2010 January to 2012 December were enrolled for study.Within 24 h after admission,inflammatory markers,blood routine items,hepatorenal function,electrolytes of blood were measured.The GCS and APACHE Ⅱ scores were recorded.Arterial blood gas analyses were performed at 0,12,and 24 h after hospitalization,and the 12-h and 24-h lactate clearance rates were calculated.Seven days after treatment,according to the outcomes,the patients were divided into survival group and death group,and the clinical data of two groups were analyzed.Results (1) Of them,73 patients died and 44 survived.Factor analysis showed that age,time elapsed from resuscitation to ICU admission,D-dimer,arterial oxygenation index (FiO2),arterial blood pH,arterial blood lactate concentration upon ICU admission,GCS score and APACHE Ⅱ score were significantly different between the two groups (P ＜ 0.05or P ＜ 0.01); (2) Two classification logistic regression analysis showed that D-Dimer,GCS score and APACHE Ⅱ score significantly correlated with the mortality risk of the patients in the wake of CPR with relative odds ratios of 1.000,2.091,and 0.531,respectively (P ＜ 0.05 or P ＜ 0.01) ; (3) Receiver operating characteristic curve analysis indicated that the area under the curve of GCS (0.821) and APACHE Ⅱ (0.869) had higher predictive value than D-dimer (0.655).The highest accuracy (84.6％) in predicting patient survival was achieved when the GCS score was 6.5.Meanwhile,the highest accuracy (82.1％) in predicting patient death was achieved when the APACHE Ⅱ score was 17.5.Conclusions Both GCS score and APACHE Ⅱ score has obvious correlation with the prognosis of the critically ill patients after CPR and could be used to predict prognosis at early stage.

A male patient undergoing extracorporeal ultrasound lithotripsy developed the symptoms of dyspnea, low blood pressure, palpitations, chest tightness, and sweating, and a clinical diagnosis of pulmonary capillary leak and hypovolemic shock was made. Pulse indicator continuous cardiac output (PiCCO) technique was used for resuscitation according to the measurements of extravascular lung water index (EVLWI) and global end-diastolic volume index (GEDI). The patient showed low levels of cardiac output (CO) and GEDI with a peak EVLWI of 32 ml/kg and profuse pink and thin sputum overflow from the trachea. The high ventilator support parameters failed to correct low oxygen saturation. Restricted fluid infusion was used to reduce pulmonary edema. Colloidal solution was given when GEDI was below 500 ml/m(2), and the volume and fluid infusion rate were reduced for a GEDI higher than 500 ml/m(2). Pulmonary edema was gradually reduced after the treatments with improvement of lactic acid level and liver and kidney functions. Vasopressors were withdrawn 6 days later, mechanical ventilation was discontinued 10 days later, and tracheal intubation was removed 25 days later, after which the patient was discharged. In the treatment of the patient, PiCCO monitoring played an important role.

Objective To evaluate the role of mitochondrial ATP sensitive potassium ( mito-KATP ) channel in dexmedetomidine-induced inhibition of subarachnoid hemorrhage ( SAH )-caused programmed cell death ( PCD) in cardiomyocytes of rats. Methods On hundred and twenty clean-grade healthy male Sprague-Dawley rats, aged 9-10 weeks, weighing 350-400 g, were divided into 5 groups ( n=24 each) using a random number table method: sham operation group ( group Sham ) , SAH group, SAH plus dexmedetomidine group ( group SD) , 5-HD plus SAH and dexmedetomidine group ( group HSD) and 5-HD plus SAH group ( group HS) . The rats were subjected to SAH by intracranial vascular puncture after being anesthetized with pentobarbital sodium. Dexmedetomidine 5 μg∕kg was infused for 10 min via the jugular vein starting from the time point after intracranial vascular puncture, followed by a continuous infusion of 5μg·kg-1 ·h-1 for 1 h in SD and HSD groups. 5-HD 30 mg∕kg was intraperitoneally injected at 1 h before intracranial vascular puncture in HSD and HS groups. Blood samples were collected from the abdominal aor-ta at 24 h after intracranial vascular puncture for determination of serum cardiac troponin I ( cTnI) concen-trations. The animals were then sacrificed, and myocardial specimens were collected for determination of PCD rate ( by TUNEL) , reactive oxygen species ( ROS) activity ( by DCFH-DA assay) , and expression of cleaved caspase-3, cleaved caspase-1 and interleukin-1beta ( IL-1β) ( by Western blot) . Results Com-pared with group Sham, the serum concentrations of cTnI, PCD rate and ROS activity were significantly in-creased, and the expression of cleaved caspase-3, cleaved caspase-1 and IL-1βwas up-regulated in SAH, SD, HSD and HS groups ( P<0. 05) . Compared with group SAH, the serum concentrations of cTnI, PCD rate and ROS activity were significantly decreased, and the expression of cleaved caspase-3, cleaved caspase-1 and IL-1βwas down-regulated in group SD, and the serum concentrations of cTnI, PCD rate and ROS activity were significantly increased, and the expression of cleaved caspase-3, cleaved caspase-1 and IL-1βwas up-regulated in group HS ( P<0. 05) . Compared with group SD, the serum concentrations of cT-nI, PCD rate and ROS activity were significantly increased, and the expression of cleaved caspase-3, cleaved caspase-1 and IL-1β was up-regulated in group HSD ( P<0. 05) . Compared with group HSD, the serum concentrations of cTnI, PCD rate and ROS activity were significantly increased, and the expression of cleaved caspase-3, cleaved caspase-1 and IL-1βwas up-regulated in group HS ( P<0. 05) . Conclusion mito-KATP channel is involved in dexmedetomidine-induced inhibition of PCD in cardiomyocytes of rats with SAH.

Objective To explore the effect of erythropoietin (EPO) attenuating apoptosis in old rat hippocampal neuronal cells exposed to sevoflurane and the role of toll like receptor 4.Methods Twenty months old SD rats,male,550-750 g,in accordance with the random number table,were divided into 3 groups (n =9):control group (group C),sevoflurane treatment (group S),and sevoflurane plus EPO treatment (group ES).The rats in group S and ES were subjected to inhale 4％ sevoflurane for 6 h,but the rats in group C were inhaled air-oxygen only.The rats in group ES were injected with EPO into caudal vein at 24 h,48 h,and 72 h after sevoflurane exposure.The cognitive ability was assessed by Morris water maze test;the effects of hippocampal apoptosis were assessed by TUNEL assays;the expressions of TLR4 mRNA was measured by RT-PCR assay;mitochondrial membrane potential (MMP) was assessed by JC-1 fluorescence;the expressions of APP and Aβ were assessed by western blot.Results Compared with group C,there were significant increases of escape latency period,neuronal apoptosis,TLR4 mRNA,and APP and Aβ expression,but a decrease of MMP in group S (P＜0.05).Compared with group S,there were significant decreases of escape latency period,neuronal apoptosis,TLR4 mRNA,and APP and Aβ expression,but a increase of MMP in group ES (P＜0.05).Conclusion The attenuation of rat hippocampal neuronal apoptosis induced by EPO could be associated with inhibition of TLR4,improvement of MMP,as well as inhibition of APP and Aβ activity.

Objective To evaluate the role of Toll-like receptor 4 (TLR4) signaling pathway in sevoflurane anesthesia-induced cognitive dysfunction in aged rats.Methods Twenty-seven SPF healthy male Sprague-Dawley rats,aged 20 months,weighing 550-750 g,were divided into 3 groups (n =9 each) using a random number table:control group (C group),sevoflurane anesthesia group (S group) and TLR4 antagonist plus sevoflurane anesthesia group (TS group).TLR4 monoclonal antibody 30 μl was injected into the lateral cerebral ventricle in group TS,and the equal volume of serum containing no antibody was injected into the lateral cerebral ventricle in C and S groups.At 10 min after completion of injection,S and TS groups inhaled the mixture of 4％ sevoflurane and 30％ oxygen for 6 h,and group C only inhaled the mixture of air and oxygen.Morris water maze test was performed at 24 h after the end of sevoflurane anesthesia.The animals were sacrificed after completion of Morris water maze test,brains were removed and hippocampi were isolated for determination of nerve cell apoptosis (using TUNEL) and expression of activated caspase-3 (using immunofluorescent staining).Nerve cell apoptosis rate was calculated.The expression of high-mobility group box 1 protein (HMGB1) mRNA in hippocampi was measured by Northern blot assay at 6 h after the end of sevoflurane anesthesia.The expression of amyloid precursor protein (APP) and amyloid beta protein (Aβ) in hippocampi was assessed by Western blot at 24 h after the end of sevoflurane anesthesia.Results Compared with C group,the escape latency was significantly prolonged,nerve cell apoptosis rate was increased,the expression of activated caspase-3,HMGB1 mRNA,APP and Aβ was up-regulated in group S,and nerve cell apoptosis rate was increased,the expression of activated caspase-3,HMGB1 mRNA,APP and Aβ was up-regulated (P＜0.05),and no significant change was found in the escape latency in group TS (P＞0.05).Compared with S group,the escape latency was significantly shortened,nerve cell apoptosis rate was decreased,and the expression of activated caspase-3,HMGB1 mRNA,APP and Aβ was down-regulated in group TS (P＜0.05).Conclusion Activation of TLR4 signaling pathway is involved in the mechanism of sevoflurane anesthesia-induced cognitive dysfunction in aged rats.
