Objective To prevent misdiagnoses of brucellosis and misjudgment of brucellosis outbreak through differential diagnosis between influenza and brucellosis of three new cases who were in the same work unit and underwent the longest latent period.Methods Contact history of the three new cases was investigated epidemiologically and physical examination and blood test were taken.Brucellosis antibodies of the cases and abortion cow were tested by serum tube agglutination test (SAT),and pathogen was isolated.The tonsilla and pharyngeal secretion substance of cases were collected for detection of influenza virus RNA by real-time PCR.Results The cases had contact history with brucellosis abortion cattle and/or the animal contaminated environment,and had a fever,fatigue and other symptoms.Total blood cell(WBC) was normal and proportion of lymphocyte was increased.The antibody titer in SAT test was 1:200(+++),but pathogen isolation was negative for all three cases.Brucellosis antibody of abortion cow was positive and antibody titer was 1:800 (++).The test of Bv RNA of influenza virus was positive in the three cases.Conclusions The three cases are brucellosis latent infection combined with influenza and we have excluded a misjudgment of pestilence of human brucellosis outbreak.

Molecular imprinting technique (MIT) involves the synthesis of polymer in the presence of a template to produce complementary binding sites in terms of its size, shape, and functional group orientation. Such kind of polymer possesses specific recognition ability towards its template molecule. Despite the rapid development of MIT over the years, the majority of the template molecules that have been studied are small molecules, while molecular imprinting of proteins remains a significant yet challenging task due to their large size, structural flexibility and complex conformation. In this review, we summarize the research findings over the past five years, and discuss the characteristics of the technique, the most recent progress and the perspective in the field of molecular imprinting of proteins.

Objective To explore the epidemiological characteristics of malaria in Liaoning Province from 1951 to 2014,so as to provide the evidence for further control of the disease. Methods The data of registered malaria cases in Liaoning Province from 1951 to 2014 were collected and analyzed with epidemiological methods. Results From 1951 to 2014,there were report-ed malaria cases each year. The peaks of incidence were in 1953,1962 and 1973,the incidence rates were 136.67/100000, 256.81/100000 and 35.89/100000 respectively and the numbers of patients were 27862,65460 and 11523,respectively. From 1977 to 2014,the incidence rates were all less than 1/100000. From 1951 to 1980,the occupations of patients were main-ly farmers,and from 1981 to 2014 were mainly workers,farmers and exported laborers. Conclusion The malaria endemic situ-ation in Liaoning Province experienced the periods from outbreaks to basically elimination,and the long-term surveillance will be the further working emphasis.

Objective:To investigate the efficacy of endolymphatic sac surgery for Meniere's disease,and compare the effects of endolymphatic sac decompression with endolymphatic-mastoid shunting.Method:Twelve patients(13 ears)undergoing endolymphatic-mastoid shunting and eleven patients (11 ears) undergoing endolymphatic sac decompression were retrospectively compared for hearing results and vertigo controlled rates.All of them have been followed up for more than two years after surgery.Result:According to Chinese Meniere's disease diagnosis and curative effect standard evaluation criteria pubilished in 2006,for vertigo symptom of endolymphaticmastoid shunting group,9 cases(69.2%) achieved grade A(eompletely controlled),4 cases (30. 8%) achieved grade B(fundamentally controlled).There were 8 cases(72.7%)with grade A, 2 cases (18.2%)with grade B and one case(90% ) with grade C among 11 patients who received endolymphatic sac decompression.There was not statistically significant differences in postoperative speech pure tone average and vertigo controlled rate between the two groups.Conslnsion:Endolymphatic sac decompression and endolymphatic-mastoid shunting are effective management with less complication for intractable Meniere's disease. Particularly,the vertigo symptoms were controlled signifisantly. Patients with Meniere's disease in advanced clinical stages may also be relieved.

Objectives:To study the postoperative nutritional support in patients with pancreatic disease. Methods:Based on the kind of pancreatic disease,twenty two patients were randomly divided into PN+EN group and TPN group during 20 days after operation.Body weight,the restoring time of intestinal movement,the complications,the blood amylase,the serum glutamic pyruvic transaminase,the blood urea nitrogen,the blood sugar,the serum albumin(Alb),transferritin(TFN) and prealbumin(PAB) were compared on the first,fifth,tenth and twentieth day after operation. Results:Body weight of two groups reduced lightly.The blood amylase decreased remarkably.The functions of liver and kidney were recovered gradually.The blood sugar tended to restore normal.Alb,TFN,PAB of two groups increased remarkably( P

Objective To investigate the characteristics of intestinal flora in infants with different feeding patterns.Methods Sixty-two cases of health infants(30-120 d)were divided into 4 groups according to their feeding patterns:breast feeding,imported powder milk feeding,domestic powder milk feeding and mixed feeding.Samples of their fresh feces in each group were collected and divided into sections equally:the bifidobacteria were isolated in anaerobic box and the number was counted for one section;for the other section,total DNA of intestinal flora was extracted and enterobacterial repetitive intergenic consensus (ERIC) fingerprints were amplified with the method of ERIC-PCR.After that,the specific bands observed in different groups were cloned and sequenced and alignmented.Results The colonies of bifidobacteria were more in breast feeding and mixed feeding groups[(9.10 ± 1.33) cfu/g;(8.62 ± 1.35) cfu/g]than those in domestic powder milk feeding and imported powder milk feeding groups[(7.62 ± 1.22) cfu/g;(7.32 ± 0.80) cfu/g,t =3.23,P ＜ 0.05];while there was no significant difference between breast feeding and mixed feeding groups,and between 2 powder milk feeding groups.Two specific bands were found from the ERIC fingerprints (A:1 100 bp mainly in breast feeding,domestic powder milk feeding and mixed feeding groups;B:1 000 bp mainly in imported powder milk feeding group).Sequencing and analysis of Basic Local Alignment Search Tool showed that homologous bacteria of A and B fragments were bifidobacterium longum.The encoding protein of A fragments might be related to the enzymes of carbohydrate metabolism,and B fragments were related to the enzymes of protein metabolism.Conclusions The colonies of bifidobacteria in intestinal tract are more in breast feeding and mixed feeding infants than those in formula feeding groups.The distribution of intestinal flora in domestic powder milk feeding infants is more similar to that of the breast feeding infants.

Objective To assess the value of magnetic source imaging (MSI) in localizing the linguistic center of auditory function of epileptic patients before operation. Methods Epileptic focus and the linguistic center of auditory function in 24 patients were localized with MSI before operation. And the relationship between epileptic focus and auditory language area was observed. Results The linguistic center of auditory function was localized in left temporal lobe in 14 patients, in right temporal lobe in 5 patients and in bilaterial temporal lobe in 5 patients. Epileptic focus was localized in left temporal lobe in 14 patients, in left temporal lobe and left parietal lobe in 1 patient, in right temporal lobe in 4 patients, in right temporal lobe and parietal lobe in 1 patient, in left frontal lobe and left temporal lobe in 1 patient, in right frontal lobe, right temporal lobe and parietal lobe in 1 patient, and in bilaterial temporal lobe in 2 patients. Epileptic focus was superimposed with the linguistic center of auditory function in 10 patients, while was not superimposed with the linguistic center of auditory function in 10 patients. The epileptic focus was localized in front of the linguistic center of auditory function in 3 patients, in behind of the linguistic center of auditory function in 1 patient. The lesion of the patient suffered from dysembryoplastic neuroepithelial tumor was not excised completely because the epileptic focus was superimposed with the linguistic center of auditory function, and the patient appeared language functional disturbance after operation in short period, remaining auditory hallucination occasionally after operation. Conclusion Epileptic focus and the linguistic center of auditory function can be localized accurately and the relationship between them can be observed clearly with MSI. MSI is useful to reduce the occurrence of language disturbance after operation.

Aim To study the effect of proteasome inhibitor MG132 on the expression of caspase-3 and apoptosis in cultured human umbilical vein endothelial cells.Methods Human umbilical vein endothelial cells was treated with MG132 (2,5 ?mol?L~(-1)) for 24 h. The apoptotic cells were determined by DNA fragment analysis and flow cytometric analysis. The level of caspase-3 mRNA was quantified by reverse transcription-polymerase chain reaction (RT-PCR). The protein contents of caspase-3 were analyzed by immunocytochemistry.Results The results showed that the increase of the degree of human umbilical vein endothelial cells apoptosis was concentration dependent. MG132 could up-regulate the gene/protein expression of caspase-3.Conclusions The results implicated that proteasome inhibitor MG132 induced human umbilical vein endothelial cells apoptosis by accumulation of caspase-3.
