A case of overseas imported quartan malaria was reported in Weihai City. The patient worked in Africa for many years had no blood transfusion history and had not been to malaria endemic regions of China. In approximately half a month af?ter returning from Africa the patient appeared suspected malaria symptoms such as irregular fever sweating and headache. The patient was diagnosed as quartan malaria by a blood test in basic hospital reviewed with a microscope by Weihai Centre for Disease Control and Prevention and checked through the microscopic examination of malaria diagnosis and reference laboratory and PCR amplification by Shandong Institute of Parasitic Diseases. The patient was cured after the treatment with chloroquine/primaquine for 8 days and did not recur in the 3?month following up.

Objective To analyze the characteristics and prognosis of intra-aortic balloown pump (IABP) supported percutaneous coronary intervention (PCI) in patients with Acute Coronary Syndrome (ACS) complicated with cardiogenic shock (CS).Methods 197 ACS patients complicated with CS patients received IABP supported PCI in Beijing Anzhen hospital from January 2014 to December 2015 were involved.According to the clinical results, all patients were divided into survival group and non-survival group.The clinical and laboratory parameters were compared between groups.Results Among the 197 patients enrolled, there were 162 patients in the survival group and 35 patients in the non-survival group.The mean age was (57.3±14.7) year-old, mean arterial blood pressure (MAP) on admission was (53.3±14.6) mmHg (1 mmHg=0.133 kPa).Percentage of diabetes comorbidity, cTnI level, oxygen index and MAP were significantly different between the survival and the non-survival groups (P<0.05).The symptom onset to balloon time and door-to-balloon time intervals were found delayed with significant difference in the non-survival group compared to the survival group (P<0.05).IABP improved hemodynamic parameters including blood pressure, cardiac function and oxygen index (P<0.05) in both groups.Duration of vasopressor usage, IABP implantation, percentage of invasive mechanical ventilation, length of stay in intensive care unit, acute kidney injury (AKI) and re-infarction were also significantly different between the two groups (P<0.05).Conclusions Adverse events risk is higher in ACS patients complicated with cordiogenic shock requiring IABP support for PCI.Patients with mortal outcomes are older, comorbid with diabetes mellitus and history of myocardial infarction and higher event rates of re-infarction and acute kidney injury during hospitalization.Intensive care should be implemented to reduce the incidence of adverse events.

OBJECTIVETo compare the shear bond strength(SBS) of cast Co-Cr alloys and selective laser melting(SLM) Co-Cr alloys with those of dental porcelain.

METHODSA dental porcelain (Vita) was applied on cast and SLM Co-Cr alloy specimens (n = 10). SBS test was conducted, and fracture mode analysis was determined. Student's t-test by SPSS 13.0 software was employed to analyze the data.

RESULTSThe SLM Co-Cr alloy specimens had lower SBS values than the cast Co-Cr alloy specimens (P > 0.05). The metal-porcelain bond strength value of the cast group was (33.11 +/- 4.98) MPa, and that of the SLM group was (30.94 +/- 5.98) MPa. The specimens in both test groups exhibited mixed failure.

CONCLUSIONThe metal-porcelain system processed by SLM exhibit a bond strength that is similar to that of the cast group. This system also display a high precision.

Objective To investigate the features of gallbladder carcinoma in two-phase spiral CT, and to analysis the values of two-phase spiral CT for the differential diagnosis between gallbladder carcinoma and chronic cholecystitis. Methods The two-phase spiral CT manifestations of 30 cases of gallbladder carcinoma, proved by surgery and pathology, and 30 cases of chronic cholecystitis were analyzed. Results According to the CT findings, the gallbladder carcinoma was categorized into 3 types: intraluminal mass of gallbladder in 6 out of 30 (20.0%), thickening of the gallbladder wall in 11 (33.7%), and mass replacing the normal gallbladder in 13(43.4%). The most common enhancement patterns of the wall in gallbladder carcinoma were hyperattenuation during the arterial phase, while isoattenuation with the adjacent hepatic parenchyma during the venous phase; or hyperattenuation during both phases. The most common enhancement pattern of the wall in chronic cholecystitis was isoattenuation during both phases, with clear hypoattenuation linear shadow in the gallbladder fossa. Other ancillary features of gallbladder carcinomas included: infiltration of the adjacent parenchyma, local lymphadenopathy and intrahepatic metastasis. Conclusion Two-phase spiral CT scan can identify the features of the gallbladder carcinoma and is helpful for the differential diagnosis of these two different disease entities.

Alveolar soft part sarcoma (ASPS) is a kind of extremely rare malignant soft tissue sarcoma, which was first discovered and defined by American scholars in 1952. Its main manifestation is painless and slow growth mass, and distant metastasis often occurs in lung, bone, brain, liver with poor prognosis. In recent years, with the accumulation of the number of cases and the development of related technology, the diagnosis and treatment of ASPS have been improved greatly. However, the primary intracranial ASPS is still rare, this paper reviews the progress of primary intracranial ASPS, in order to provide help for its clinical diagnosis and treatment.

AIM: To investigate the changes of expression of SR-BI in phorbol 12-myristate 13-acetate(PMA) differentiated U937 cells.METHODS: U937 cells were cultured with 100 nmol/L PMA in order to differentiate the cells to macrophages.Immunocytochemical method,Western blotting analysis and reverse transcription polymerase chain reaction(RT-PCR) were used to detect SR-BI protein and mRNA during differentiation.RESULTS: Immunocytochemistry showed that after exposure of U937 cells to PMA for 24,48,72 hours,the values of SR-BI protein expression in U937 cells were 15.94?3.56,27.86?4.39 and 9.08?2.37,with the first two higher than that in undifferentiated cells(7.76?1.74,P0.05) increment in the expression of SR-BI protein compared with U937 monocytes.RT-PCR showed that relative SR-BI mRNA expression in different group was 0.112?0.006,0.235?0.014,0.344?0.140 and 0.138?0.010,respectively.CONCLUSION: SR-BI protein and mRNA were increased after differentiation,reached a peak at 48 hours,and decreased at 72 hours.High expression levels of SR-BI in U937 macrophages following PMA differentiation may be correlated with foam cell formation.

Objective To detect attenuated plaque by using intravascular ultrasound (IVUS) in patients with acute myocardial infarction (AMI) and to investigate the influence of attenuated plaque on perioperative period of percutaneous coronary intervention (PCI). Methods Coronary angiography and IVUS were performed in 85 hospitalized patients with AMI, additional implantation of stent was employed when necessary. According to the presence or absence of attenuated plaque determined by IVUS, the patients were divided into attenuated plaque group(n=35) and non-attenuated plaque group(n=50). The perioperative IVUS findings, the blood flow classification after myocardial infarction thrombolysis (TIMI) and the postoperative peak value of creatine kinase MB (CK-MB) determined were compared between the two groups. Results Among the 85 AMI patients, attenuated plaque was detected in 35 (41.2%) and no attenuated plaque was found in 50(58.8%). No statistically significant differences in the age, sex and risk factors existed between the two groups (P>0.05). The proportion of having attenuated plaque in patients with ST segment elevation myocardial infarction (STEMI) was obviously higher than that in patients with non-STEMI (P<0.01). In performing coronary angiography, the difference in TIMI blood flow classification between the two groups was not statistically significant (P>0.05), but after balloon dilatation the TIMI grade 0-2 in theattenuated plaque group was strikingly higher than that in the non-attenuated plaque group (P=0.003). After PCI, the proportion of patients with elevated CK-MB value and higher peak value in the attenuated plaque group was remarkably higher than those in the non-attenuated plaque group (P<0.01). Conclusion The results of this study indicate that attenuated plaque can increase the incidence of no-reflow and slow reflow after PCI, which is more often seen in STEMI patients. The attenuated plaque carries significantly high risk, and the presence of attenuated plaque is helpful in predicting, the elevated extent of CK-MB value after PCI.
