Objective To investigate the CT diagnostic value and CT findings of fungal sinusitis.Methods CT findings of fungal sinusitis in 25 cases proved pathologically were retrospectively analysed.Results Heterogeneous density of sinusal cavity with small calcification appeared as spots or floccose(9 cases) and sand-like or patchy(16 cases) shadows,and local bone destruction.Conclusion The fungal sinusitis has characteristic findings on CT.CT is a valuable method for diagnosing the disease.

Objective: To explore how social support in students of normal college related to their interpersonal attribution and philosophies of human nature, and whether social support varied with different subgroups. Method: Social Support Rating Scale, the Multidimentional-Multiattributional Causality Scale and Revised Philosophies of Human Nature Scale were used in 414 students of a normal university. Result: The social support of students differed significantly among different departments, students of science had lower social support than students of art or sport had. There was no significant difference of social support between sexes, different grades, of urban or rural area. Social support was significantly correlated with "effort" attribution of interpersonal relationship, but not with "ability, background or luck". Social support was positively related to trustworthiness, while negatively to cynicism. Conclusion: This result fits for the common sense of Chinese and people elsewhere.

Objective To analyze effect of oxycodone hydrochloride injection preemptive analgesia on serum cellular immune factors and analgesic effect in postoperative patients with humeral fracture surgery.Methods 52 patients treated by surgical treatment of humeral fractures in our hospital were collected.All patients were randomly divided into experimental group and control group,26 cases in each group.Preemptive analgesia drugs were given corresponding, before and 24h after surgery, the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), venous blood CD4 +T, CD8 +T cells and CD4 +/CD8 + T levels and analgesic effect were detected in all patients.Results After surgery, compared with control group, the serum levels of TNF-αand IL-6 were lower in experimental group (P<0.05); the venous blood CD4 +T cell and CD4 +/CD8 + T levels were higher(P<0.05), CD8 +T cell level was lower in experimental group (P<0.05);the visual analogue scale(VAS) score was significantly lower in 2,4,6,12 and 24h after surgery in experimental group (P<0.05).Conclusions The oxycodone hydrochloride injection preemptive analgesia can significantly inhibit the increase of the serum TNF-αand IL-6 levels, prevent the decrease of immune function, improve the analgesic effect.

Objective To observe the effect of rapid reduction of physical activity on bone mass (BMC), bone mineral density (BMD)and bone metabolism in growing rats. Methods 48 male SD rats were divided into the high-intensity exercise group (T1, n=12), high tolow-intensity exercise group (T2, n=12), low-intensity exercise group (T3, n=12) and control group (Con, n=12). During the first 6 weeks,the rats in T1 and T2 group ran on treadmill with high intensity, while rats in T3 group took low-intensity treadmill exercise. 6 rats were sacrificedfrom each group at the end of 6th week. BMC, BMD of femur were measured with DEXA. Alkaline phosphatase (ALP), osteocalcin(BGP), tartrate-resistant acid phosphatase (TRACP) were detected with ELISA. The exercise intensity of T2 group was reduced rapidly to alow level as in T3 group, but remained in the other 2 groups. At the end of the second 6 weeks, the other rats were investigated again. ResultsCompared with the first measurements, ALP and BGP of the T2 group decreased significantly (P<0.05), and TRACP increased (P<0.05). There was no significant difference in BMC and BMD of femur (P>0.05). Conclusion Rapid reduction of physical activity can suppressbone formation and stimulate bone resorption of long bone among growing rats.

Neurodegenerative disease is characterized by progressive loss of neurons in specific brain regions that results in neuronal dysfunction of the central nervous system. Although the pathological mechanism is not fully established, the activation of glial cells mediated neuroinflammation appears to be involved. Heat shock protein 70 (HSP70) is originally described as intracellular chaperone, which plays an important role in protein quality control in cells. However, recent study showed that up-regulation of HSP70 had anti-inflammatory effects in the brain. HSP70 protected neurons from damage and improved neurological function by decreasing inflammatory response as indicated by inactivation of glial cells and inhibition of pro-inflammatory cytokine release. So it is of great significance to find new compounds targeting at HSP70 as neuroprotective agents to delay the progress of neurodegenerative disease. This review will focus on the role of HSP70 in neuroinflammation and the recent advances in using HSP70 as a target for the treatment of neurodegenerative disease.

Objective To investigate the expression of aquaporin-3 (AQP3) in tongue tissues of rats with experimental severe acute pancreatitis (SAP) and regulating effects of emodin. Methods Rat models with SAP were established by injecting 5% sodium taurocholate retrogradely into gallbladder and pancreas. SD male rats were randomly divided into sham-operation group, model group, and emodin group. After model establishment, rats in the emodin group received gavage with emodin 20 mg/kg each day, while rats in the model group and sham-operation group received gavage with normal saline. The mental state, thick greasy tongue fur and mortality of rats were observed every day after model establishment, and 5 days later, protein and genetic expression of AQP3 were detected by Western blot and RT-PCR. Results Compared with the model group, the mortality and the thick greasy tongue fur significantly decreased, the protein and genetic expression of AQP3 significantly decreased in the emodin group (P<0.05). On the 5th day, 11 rats in the model group survived, and 5 rats had thick greasy tongue fur. Compared with the sham-operation group, the protein and genetic expression of AQP3 in the model group were higher (P<0.05). Conclusion Emodin can improve the severity of SAP and decrease the incidence of thick greasy tongue fur significantly by reducing the protein and genetic expression of AQP3.

Objective To study the effect of myocardial infarction induced by distal left ascending artery occlusion on left ventrieular(LV) synchronism. Methods Routine echocardiography and vector velocity imaging were performed within 2 hours before and 7-14 days after myocardial infarction by occluding distal left ascending coronary arteries in experimental pigs. Routine eehocardiographie parameters of LV, including end diastolic and systolic diameters, volumes, and spherical indexes were measured or calculated. Six segmental peak systolic velocity, strain and strain rate were compared between pre- and post-myocardial infarction. Results After myocardial infarction, LV end diastolic, end systolic long diameter and end systolic volume increased with decreased ejection fraction. With the 6 segmental systolic velocity, strain and strain rate significantly reduced,the mean 6-segmental time to peak strain rate delayed significantly. Conclusions Abnormal synchronism after myocardial infarction may aggravate LV systolic dysfunction.

BACKGROUND:In 2004, a new biomarker sCD14-subtypes (presepsin) was found and its value was shown in the diagnosis and evaluation of sepsis. This article is a brief overview of the new biomarker. DATA SOURCES:A literature search using multiple databases was performed for articles, especially meta-analyses, systematic reviews, and randomized controlled trials. RESULTS:Compared with other markers, presepsin seems to have a better sensitivity and specificity in the diagnosis of sepsis. Presepsin as a biom1arker is not only suitable for the early diagnosis of sepsis, but also for the assessment of its severity and prognosis. CONCLUSIONS:Presepsin has a higher sensitivity and specificity in the diagnosis of sepsis as a new biomarker, and is a predictor for the prognosis of sepsis. More importantly, preseptin seems to play a crucial role as a supplemental method in the early diagnosis of sepsis. Since there is no multicenter study on the relationship between presepsin and sepsis, further studies on the clinical values of presepsin are needed.

Objective To analyze imaging of gastrointestinal stromal tumors(GIST),and to compare their imaging features with operational and pathological findings.Methods Clinical,imaging,and pathological data of 20 patients with GIST were collected.Results Imaging findings were endophytic or exophytic tumors with heterogeneous density or signal intensity,corresponding to hemorrhage,necrosis,and cystic changes.Imaging was correct for the location of the lesion in 11 of 16 primary GIST and 4 cases of relapsed tumors.Preoperational CT did not detect mesenteric,peritoneal,and omental metastasis in 5 cases. Hepatic metastases detected at CT (3 cases )were identified by operational findings.Conclusions GIST has some imaging features.CT is a useful tool in detecting and characterizating of lesions rather than detecting mesenteric,peritoneal,and omental metastasis.
