Objective To investigate the clinical value of color Doppler ultrasound in the early diagnosis of acute cholecystitis infection ,in order to improve the diagnosis of acute cholecystitis infection .Methods 36 cases with acute cholecystitis infection were selected as the observation group , and during the same period the healthy people were randomly selected as the control group .The color Doppler performance of ultrasound was observed .The hepatic artery blood flow velocity and the maximum peak of the cystic artery (Vmax) and resistance index(RI) were meas-ured.ROC curve was observed to evaluate the specificity of color Doppler ultrasound for the disease .Results The incidence rates of weak bile sound transmission ,gallbladder wall thickness ,gallbladder enlargement ,ultrasound Mur-phy positive in the control group were 25.0%,16.7%,22.2%,8.3%,which in the observation group were 72.2%, 47.2%,100.0%,94.4%,the differences were statistically significant (χ2 =4.571,4.571,4.589,5.689,all P<0.05).The differences in hepatic artery and the cystic artery Vmax and RI were statistically significant between the two groups(P<0.05).ROC curve comparison showed that the correct rate of gallbladder enlargement in the observa -tion group was the highest (90.7%),the specificity was 90.7%,sensitivity was 90.6%,and other indicators of ultra-sound had no significant difference (χ2 =0.893,P>0.05).Conclusion Color Doppler ultrasound can show the form of acute infectious cholecystitis ,gallbladder wall degree of bile through sound etc .,it can improve the diagnostic value of the disease.

Objective To explore the neuroprotective mechanism of propofol by comparing the influence of propofol and isoflurane on inflammatory cytokines ( TNF-α、IL-1、ICAM-1 ) in patients with intracranial tumors. Methods One hundred and sixty-eight patients with intracranial neoplasm were randomly divided into two groups:the propofol ( Group P) and isoflurane (Group I),84 cases in each. Patients were given with propofol (3-6 μg·mL-1) by plasma target-controlled infusion or with continuously inhaled isoflurane ( 1%-2%) , respectively. The serum levels of TNF-α, IL-1 and ICAM-1 were detected before anesthesia and at 0,24,and 48 h after operation. Results The serum levels of TNF-α,IL-1 and ICAM-1 were significantly increased after operation as compared to baseline in both groups. The serum level of TNF-α was(69. 11±8. 95) and (76. 26±11.28) μg·mL-1,IL-1 was(21.57±3.19) and (29.58±4.38) ng·L-1,and ICAM-1 was (1.63±0.24)and (1.94±0.29) g·L-1 at 24 h post operation in Group P and Group I,respectively. These inflammatory cytokine levels were significantly higher in group I compared to group P at 24 and 48 h after operation (P<0. 05 or P<0. 01). Conclusion The target-controlled infusion of propofol brings about lower level of inflammatory reaction than isoflurane inhalation in patients with intracranial neoplasm,which may attribute to the mechanism of brain protection against injury.

Objective To explore the regulation and effect factors of arsenic expose and arsenic methylation level, then to provide a reference for study the function of arsenic metabolism in a arsenic poisoning process. Methods A meta-analysis was performed by two researchers. Twenty-five papers satisfying our priori eligibility criteria were included by searching Cochrane library, Pubmed, Springer, Embase and China National Knowledge Infrastructure. Based on the results of heterogeneity, a random or fixed effects model was chosen for the meta-analysis. Results The results showed that the following arsenic metabolites increased (all P<0.01) following arsenic exposure: inorganic arsenic [iAs; standardized mean difference (SMD): 1.07; 95% confidence interval (CI):0.61 - 1.53)], monomethyl arsenic (MMA; SMD: 1.10; 95% CI: 0.81 - 1.40), dimethyl arsenic (DMA; SMD: 2.50;95%CI:1.50-3.69), and total arsenic (TAs, SMD:3.10;95%CI:2.13-4.07). Additionally, the percentages of iAs (iAs%; SMD: 1.00; 95% CI: 0.60 - 1.40) and MMA (MMA%; SMD: 0.49; 95% CI: 0.21 - 0.77) also increased, while the percentage of DMA (DMA%; SMD: - 0.55; 95% CI: - 0.80 - - 0.31) decreased (P<0.01). The primary methylation index (PMI; SMD: - 0.57; 95% CI: - 0.94 - - 0.20), and secondary methylation index (SMI;SMD: - 0.27; 95% CI: - 0.46 - - 0.09) decreased (all P< 0.01). Compared to female, male had higher MMA%(SMD:0.44;95%CI:0.35-0.52), lower DMA%(SMD:-0.33;95%CI:-0.38--0.28) and SMI (SMD:-0.36;95%CI:-0.53--0.19). The smoker had higher MMA%(SMD: 0.22; 95%CI: 0.07 - 0.37) and lower DMA%(SMD:-0.16;95%CI: - 0.26 - - 0.05). The drinker had higher MMA% (SMD: 0.17; 95% CI: 0.07 - 0.27) and lower DMA%(SMD:-0.24;95%CI:-0.39--0.10). The older people had higher MMA%(SMD:-0.23;95%CI:-0.40--0.06). In addition, the body mass index may influence the percentages of MMA (SMD: - 0.18; 95% CI: - 0.31 - - 0.04, P < 0.01). Conclusion Arsenic exposure, smoking, drinking, and older age can reduce the capacity of arsenic methylation. Arsenic methylation is more efficient in women than in men.

Objective To compare the effects of non-steroidal anti-inflammatory drugs (NSAIDs) and free radical scavengers (FRS) on formation of traumatic heterotopic ossification (HO) in rabbits. Methods 48 New Zealand rabbits were randomly divided into control group (n=12), NSAIDs group (n=12), FRS group (n=12) and combination group (n=12). The model of traumatic HO was established, and the NSAIDs group, FRS group and combination group were administered indometacin intragastrically, edaravone intravenously and both, respectively, while the control group was administered normal saline for 4 weeks. The incidence and severity of HO were observed with X-ray 8 and 12 weeks after modeling. Results 8 and 12 weeks after operation, the incidence of HO was 33.3% and 41.7% in the NSAIDs group, 43.0% and 45.8% in the FRS group, 29.2% and 37.5% in the combination group, and 70.8% and 75.0% in the control group, respectively. The incidence and severity of HO in all the treatment groups were significantly less than those in the control group (P<0.05), and there was no significant difference among the treatment groups (P>0.05). Conclusion The systemic application of FRS may prevent the formation of HO effectively, similar with the NSAIDs. There is no synergistic effect between them.

Objective To investigate the etiologic effect of the lumbar facet joint morphology on the occurrence of degener?ative lumbar spondylolisthesis (DLS). Methods From January 2007 to July 2013, 115 patients with DLS treated in our hospi?tal were randomly selected. There were 28 males and 87 females with an average age of 57.3 years (range, 41-76 years). 115 age? and sex? matched people including 31 males and 84 females with an average age of 56.4 years (range, 45-77 years) free from DLS and back or leg pain were selected randomly as control group from a group coming for routine physical examination in our hospital. Both groups received lumbar anteroposterior and lateral X?ray films、CT scanning and multiplanar reformation, the degree of spondylolisthesis (Taillard index) was measured in DLS group on lateral radiographs; at L3,4 and L4,5 level of both groups the facet joint angles on CT scan images were measured and facet tropism was evaluated, the pedicle?facet angle (the P?F angle) was measured in the sagittal plane on multiplanar reformation CT images, and then all angles of corresponding level were compared and analyzed; L4,5 facet joint degeneration in both groups was evaluated and compared in bone window, the de?gree of spondylolisthesis (Taillard index) in DLS group at different degenerative grade of facet joints were analyzed. The corre?lation between L4,5 facet joint angle、P?F angle and degrees of spondylolisthesis were analyzed. Results All L4,5 spondylolisthe?sis in DLS group were grade I, the facet joint angles were more sagittal in DLS group than those in the control group at L 3,4 and L4,5 levels, and the P?F angles were more horizontal in DLS group compared with control group;the facet tropism in DLS group at L 4,5 level were significantly different as compared to the control group, but there was no significant difference at L 3,4 level between the two groups. Significant difference was found in L4,5 facet joint degeneration grade between two groups,but there was no significant difference in degree of spondylolisthesis during different degeneration grades in DLS group. There was no significant correlation between the facet joint angle and the P?F angle and degree of spondylolisthesis at L4,5 level in DLS group. Conclusion The facet joint morphology abnormality (smaller facet joint angle, horizontal P?F angle, the facet tropism) has an important etiologic meaning in the occurrence of degenerative lumbar spondylolisthesis, however its role cannot be excessively exaggerated. The facet joint de?generation is a secondary change with aging,while the development of DLS aggravates the degeneration.

Objective To investigate the impact of sputum suction under laryngoscope in stroke patients on the occurrence and prognosis of ischemic stroke-associated pneumonia (SAP).Methods A total of 127 cases with acute ischemic stroke (AIS) with Glasgow Coma Scale 6-12 scores,non-artificial airway and need for intensive care were enrolled.According to the suction practice,the cases were divided into laryngoscope euthyphoria group (practice group,PG,n =59),and conventional oral or nasal sputum suction group (control group,CG,n =68).The PG was perspectively studied,while the CG were analyzed retrospectively.All patients were cared with the Guidelines for the management of adult with hospitalacquired ventilator-associated and healthcare-associated pneumonia set by American Thoracic Society/Infectious Diseases Society of America in 2005 and the Guidelines for the early management of patients with acute ischemic stroke set by American Heart Association/American Stroke Association in 2013 including patting on the back of patients in prone position routinely in order to facilitating expectoration,phlegm elimination with physical vibration and apophlegmatic agent application during their stay in ICU.Incidences of SAP and 28-day mortality were calculated.Levels of inflammatory markers (white blood cell,WBC;highsensitive C-reaction protein;procalcitonin,PCT) in serum were detected.Adverse events related to laryngoscopy were documented.Results There were no significant differences in incidences of SAP and 28-day mortality between PG and CG groups (32.20％ vs.41.18％,P ＞ 0.05;47.37％ vs.53.57,P ＞ 0.05,respectively).However,there was statistically significant difference (P ＜ 0.05) in the ICU stay length and inflammatory markers,and the sputum suction process in PG did decrease the incidence of artificial airway establishment and mechanical ventilation (18.64％ vs.35.29％,P ＜ 0.05),and the laryngoscope euthyphoria method was proved to be a protective factor (HR =0.515;95％ CI 0.281-0.057,P =0.038).WBC and PCT were lower in PG group than in CG group (P ＜ 0.05).Conclusion Sputum suction under laryngoscope can reduce the probability of artificial airway establishment and invasive ventilator employment in patients with AIS,shortening ICU stay length and down-regulating levels of WBC and PCT.
