Objective To detect the mRNA expression of KPNA2 in hepatocellular carcinoma(HCC) tissue and to investigate its relationship with the clinicopathological features of HCC so as to provide the basis for predicting HCC infiltration ,metastasis and early treatment .Methods The HCC tissue and paracarcinoma normal tissue from 30 operative cases of HCC in the hepatobiliary surgery department of this hospital from January 2011 to November 2013 were collected and detected KPNA2 expression at the transcriptional level by RT-PCR .The correlation between the mRNA expression of KPNA2 with the clinicopathological factors of HCC was analyzed by consulting the medical record data .Results Among 30 cases of HCC ,the ratio of KPNA2 mRNA in the HCC tissue and the paracarcinoma normal tissue in 25 cases(83 .33% ) was up-regulated (grey value >2 times) .Therefore ,the KP-NA2 gene exhibited the high expression in the HCC tissue and low expression in the paracarcinoma normal tissue .Conclusion KP-NA2 is highly expressed in the HCC tissue and lowly expressed in the paracarcinoma normal tissue ;the high expression of KPNA2 is positively correlated with the stage and pathological grading of HCC ;KPNA2 may be used as an important indicator for early di-agnosing HCC and judging the malignant degree and potential metastais ability of HCC .

Objective To investigate the characteristics of pathogen distribution and drug resistance of pulmonary infection in hemorrhagic brain injury patients from neurosurgical intensive care unit (NICU).Methods Clinical data of 234 patients with hemorrhagic brain injury hospitalized in NICU from March 2013 to September 2014 were retrospectively analyzed.According to the incidence of pulmonary infection,the patients were divided into pulmonary infection group and non-pulmonary infection group.Parameters estimated were admission GCS,sex,age,history of smoking,time of coma,duration of mechanical ventilation,NICU length of stay.Patients in pulmonary infection group were analyzed on the distribution of pathogens and incidence of drug resistance.Results A total of 158 patients (67.5％) had pulmonary infection.Among them 60 cases (38.6％) were found to be co-infected including infection with two pathogens in 26 cases (16.5％),three pathogens in 19 cases (12.0％),and four and more pathogens in 16 cases (10.1％).Age and smoking increased the incidence of pulmonary infection (P ＜ 0.05).Time of coma,duration of mechanical ventilation,and NICU length of stay were prolonged in pulmonary infection group than in non-pulmonary infection group (P ＜ 0.05).A total of 219 strains of pathogens were isolated from the patients in pulmonary infection group.Specifically,there were 193 strains of gram negative bacteria (88.1％),13 strains of gram positive bacteria (5.9％),and 13 strains of fungi (5.9％).Gram negative were sensitive to amikacin,imipenem,cefoperazone/ sulbactam and ciprofloxacin.Staphylococcus aureus isolated were 100％ sensitive to vancomycin,linezolid and teicoplanin,and were completely penicillin resistant.Fungi were not resistant to voriconazole,itraconazole,ketoconazole,fluconazol,and amphotericin B.Conclusions High incidence of pulmonary infection is noted among the hemorrhagic brain injury patients in NICU,and the pathogens are diverse dominated by Gram negative bacteria.Incidence of multi-drug resistant pulmonary infection is high,indicating that the key point is to choose antibiotics rationally based on drug sensitivity test.

OBJECTIVETo compare the reactogenicity and serology between influenza subunit vaccine and split vaccine.

METHODSA randomized, double-blind study was carried out among children (age 6 - 12 years) in order to compare the safety and immunogenicity of an influenza inactivated subunit vaccine (Agrippal, Chiron Vaccines) with that of a split vaccine (Flurix, GSK).

RESULTSA total of 499 subjects were vaccinated and included in the safety analysis. A total of 249 subjects received Agrippal and 250 received Flurix. All subjects were kept under medical observation for 30 minutes in order to check the evidence of having any immediate local and systemic reaction. Daily observation records were collected during the 3-day follow-up after vaccination. 6.4% of the cases with fever >or= 37.5 degrees C was reported in the Flurix group, but 2.4% in Agrippal group which was significantly less than the former group (P > 0.05). Blood samples (the D0 pre- and D23 post-vaccination sera) were collected from 224 of Agrippal group and 223 of Flurix group and analysed by the haemagglutination inhibition (HI) assay. Agrippal and Flurix induced similar seroprotection (HI titer >or= 1:40, H1N1 99.6% vs 100.0%; H3N2 99.1% vs 99.1%) and seroconversion (4-fold increase, 95.1% vs 97.8%; H3N2 74.5% vs 79.8%) rates and geometric mean titer (GMT) increase (16.0 vs 21.0; 5.4 vs 6.4) against the two A subtypes. A similar seroprotection rate (94.2% vs 96.4%) and GMT increase (21.2 vs 18.2) against the influenza B strain were also noticed in both vaccines. No significant difference was found in the results of immunological assay between the two vaccines (P < 0.05). A lower seroconversion rate against B strain was observed in Agrippal group than in Flurix group (91.1% vs 97.3%).

CONCLUSIONIn terms of safety, both vaccines were generally well tolerated. The fever reaction was less frequently seen in the Agrippal group. Both vaccines induced an effective immune response in the vaccines.

OBJECTIVETo investigate the progression of visual field loss and to explore the prognosis of glaucomatous optic neuropathy in patients with chronic angle-closure glaucoma (CACG) after their intraocular pressures were well controlled under 21 mmHg.

METHODSForty-seven eyes of 29 patients in the Department of Ophthalmology in PUMC Hospital were included. All the patients had at least two separate tests of visual fields using the 24-2 program of the Humphery Visual Field Analyzer after their intraocular pressure were well controlled under 21 mmHg after sugery. The visual fields of patients were followed routinely for at least 1 year. In addition, all patients were divided into 2 groups according to follow-up period: 1-2 years group and over 2 years group. Visual field scores were calculated with the Advanced Glaucoma Intervention Study (AGIS) method. The visual fields were divided 5 sections and the sensitivity and defect depth of each section were calculated.

RESULTNo statistically significant differences were found in terms of AGIS scores, localized sensitivities and localized defects within the time interval of the observation.

CONCLUSIONGlaucomatous optic neuropathy is not likely to progressively deteriorate in CACG cases once their intraocular pressure are well controlled under 21 mmHg.

OBJECTIVETo study the frequency distribution in polymorphism of the apoprotein B 3' variable number tandem repeat (ApoB3'VNTR) and influence factors on hyperlipemia in civil aircrew.

METHODSApoB genotypes were determined by PCR technology and agarose gel electrophoresis. The blood lipids were measured by routine kits. Personal information of flight personnel was collected by questionnaire.

RESULTSPrevalence of the total dyslipidemia (49.5%) and overweight (55.6%) of flight personnel were much higher than that of domestic general population (29.2% and 49.1%) respectively (P < 0.05). There were 16 alleles and 54 kinds of genotypes of ApoB3'VNTR in the 682 flight personnel. The frequency distribution of alleles and genotypes of aircrew in the two air companies had same trend, which was different from the general population. The frequency of the homozygote was 76.54%, which was much higher than that of the other peoples home and abroad (21.50%). The frequency of the big allele (VNTR > or =39) in hyperlipemia groups were higher than that of normal groups. By analysis of co-variance, the body mass index (BMI), low density lipoprotein (LDL) and the total cholesterol(TC) increased with the cumulate flight hours (P < 0.05). In multivariate logistic regression analysis, the BMI was the only factor influencing blood lipids, and the cumulate flight hours was only factors affecting the BMI. Taking the cumulate flight hours logarithm as the independent variable(X), and the BMI as dependent variable(Y), the linearity equations was: Y = 2.730X + 13.584 (R2 = 0.159, P < 0.01).

CONCLUSIONThere are perhaps special genetic characteristics in the polymorphism of the ApoB3'VNTR in the aircrew. The big allele is correlated with the hyperlipemia. The flight burden not only directly affects the BMI and blood lipids levels, but also it can indirectly affect the lipids levels by BMI.

OBJECTIVETo identify epidemic status of murine typhus in Hongta areas of Yuxi city and to provide evidence for control and prevention of the disease.

METHODSSerologic survey was conducted among residents and rodents. Isolation of Rickettsia moseri was performed.

RESULTSThe overall infection rate among general population was 28.92% (96/332) with geometric meantiter (GMT) as 10.83 and there was no difference between males and females (26.71%, 43/161 vs. 30.99%, 53/171, P > 0.05). Significant differences were found between age groups (P < 0.05) with positive rates of 29.63% (8/27), 18.06% (13/72), 39.62% (42/106), 27.50% (22/80) and 23.40% (11/47) among age groups 0-6, 7-18, 19-39, 40-59 and over 60, respectively. The overall rate of infection in mouse was 44.95% (89/198) with GMT as 30.30. Five isolates of R. moseri from mouse specimen, three from fleas plus one case of murine typhus were diagnosed. Rattus norvegicus and Rattus flavipectus were the predominant species of rodent animals (99.49%, 197/198) and Xenopsylla cheopis was the major species of vector (74.26%, 303/408). Flea index and mouse density were 2.06 and 11.13% respectively.

CONCLUSIONHigh infection rates on R. moseri were demonstrated in rodents and residents as well as high risk of murine typhus outbreak might occur in these areas.

BACKGROUNDRoux-en-Y gastric bypass (GBP) is the main surgical procedure used in type 2 diabetes. The objective of this study was to evaluate the different types of GBP in treatment of type 2 diabetes.

METHODSPatients with type 2 diabetes were randomly divided into two groups: those who underwent gastrojejunal loop anastomosis bypass and those who underwent gastrojejunal Roux-en-Y bypass. Blood glucose alterations, operation time, and operation complications were observed.

RESULTSGastrojejunal loop anastomosis bypass and gastrojejunal Roux-en-Y bypass were both effective in the treatment of selected patients with type 2 diabetes. Compared with gastrojejunal Roux-en-Y bypass, gastrojejunal loop anastomosis bypass had the advantages of easier implementation, shorter operation time, and fewer operation complications.

CONCLUSIONSGastrojejunal loop anastomosis is effective in treatment of type 2 diabetes. It is safe, easy to implement, and worthy of clinical popularization.

OBJECTIVETo understand the clinical and epidemiological aspects of avian influenza A (H7N9) virus infection in children.

METHODThe clinical data of the first confirmed pediatric case of avian influenza A(H7N9) virus infection were collected, and the epidemiological information, presenting symptoms, laboratory investigation, management and outcome were analyzed. The data of the pediatric cases were also compared with those of the adults cases.

RESULTThe case reported in this paper was a previously healthy 3.6-year-old boy residing in rural area of Shanghai. He had onset of fever and mild rhinorrhea on 31 March 2013 and he was afebrile and well since April 3. Influenza A (H7N9) virus was detected in his nasopharyngeal sample collected on 1 April through national Influenza-like Illness surveillance using real-time reverse transcriptase PCR and virus culture.His family raised domestic poultry with no apparent disease and there was no virological evidence of H7N9 infection. Monitoring and testing of 16 contacts had not found any secondary infection.

CONCLUSIONThe clinical course of H7N9 avian influenza virus infection in children was relatively mild as compared to adult cases. The source of infection and detail of exposure for children have not been known yet. Continued surveillance studies of mild and severe respiratory disease and subclinical infection are essential to further characterize the epidemiology and clinical spectrum of this emerging H7N9 virus infection in children.
