Objective To observe the lung inflammation and the expression of T - helper cell related cytokines in respiratory syncytial virus(RSV) infected Balb/c mice pre - sensitized with ovalbumin(OVA). Methods Mice were randomly divided into two series: nonsen-sitized and sensitized animal model with nebulized OVA once a day for 10 days. Each of the series was divided again into two groups: control group,RSV infected group with nasal draping plus nebulizing. All the mice were sacrificed 5 days later of infection. Viral isolation of lung organization was performed in each group. Pulmonary pathological detection and the levels of interleukin - 4(IL-4), interferon-? (IFN- ?) mRNA were evaluated by RT- PCR. Results The RSV were found only in RSV infected groups. The Balb/c mice developed typical interstitial pneumonia after RSV infection. When the mice pre- sensitized were infected with RSV, the pulmonary inflammation, lymphocyte and eosinophils infiltration and cell - collar peribronchiles were more severe in lung organization and bronchiole than those in the single RSV infection group. In the lung organization of control group, there were no mRNA expression of IL - 4 and IFN - ?. The mRNA of IFN -? was expressed in the lung organization of RSV infected groups while had not showed mRNA of IL- 4. In the OVA+ RSV group the mRNA expression of IL - 4 was obvious, while the expresses of IFN -? scarcely. Conclusions Pulmonary inflammation is more severe in the infection after OVA sensitization. RSV infection alone results in a Th1 - like cytokine response, while the infection after OVA sensitization results in Th2 - like response.

Objective To evaluate the clinical efficacy of transthoracic two dimensional echocardiography, cardioangiography (CAG), and MRI in the diagnosis of cor triatriatum. Methods Twelve cases of cor triatriatum were confirmed by operation. Imaging examination was performed in 12 cases by transthoracic two dimensional echocardiography, 6 cases by CAG, and 8 cases by MRI. Results The diagnostic accuracy of cor triatriatum was 7 out of 12 by UCG, 4 out of 6 by CAG, and 8 out of 8 by MRI, respectively. MRI provided excellent delineation of the intraatrial membrane and the size of the membrane orifice. Conclusion MRI was of great value in the diagnosis of cor triatriatum.

To interpret the traditional Chinese medicine (TCM) theory by the network technology, in order to promote the modernization and programming of studies on compatibility of TCMs. In this paper, efforts were made to express the direct interactions between drugs through the herb-pair network, analyze the community characteristics of the network and its relations with blood-Qi theory, and study the expression of blood-Qi theory on the herb-pair network through prescriptions. According to the findings, the herb-pairs network showed a strong community structure characteristics; Each community is composed of a series of herb pairs with close correlations, and either blood efficacy or Qi efficacy but not both of them. Based on that, the 386 single TCM ingredients involved by the herb-pair network were divided into three types of communities: Blood (B) community, Qi (Q) community and uncertain community. According to the statistical results of 262 prescriptions mapped onto the three types of communities, if a prescription contains single herbs of the Q community, the probability that it contains single herbs o the B community is 99.84%; Meanwhile, there are 140 prescriptions containing single herbs of both the Q community and the B community. The result is completely coincident with the TCM Blood-Qi theory that single herbs belong to both Q and B communities or the B community, because Qi regulation leads to blood regulation, but not vice versa. For example, a patient with hemorrhage due to trauma or blood-heat, Qi tonifying prescriptions may aggravate hemorrhage. In this paper, authors found high-recognition macroscopic network numerical characteristics to network data reference for judging rationality of new prescriptions, and proved human blood and Qi relations from the perspective of data analysis.

Objective To investigate the distribution and drug resistance of pathogens for hospital-acquired urinary tract infections between patients in internal medicine wards and in surgical wards .Methods A total of 586 midstream urine samples were collected from patients in the First Municipal Hospital of Qinhuangdao during January 2012 and December 2014.Vitek 2 Compact system was applied in bacteria identification and drug sensitivity tests .Excel and SPSS 11.5 software were applied for data analysis . Results A total of 661 strains were isolated , in which 404 strains were from internal medicine wards and 257 strains were from surgical wards .Escherichia coli (44.6%vs.33.1%) and Enterococcus (23.0%vs. 16.3%) infections were more common in the internal medicine wards (χ2 =8.620 and 4.309, P<0.05), while the occurrence of Pseudomonas aeruginosa infection (4.0%vs.24.5%) was higher in surgical wards (χ2 =63.056, P <0.01).Escherichia coli and Klebsiella pneumonia strains were highly sensitive to piperacillin/tazobactam, cefptetan, amikacin, imipenem, and meropenem, and the sensitivity rates were from 85% to 100.0%.The sensitivity rates of Escherichia coli to ampicillin/sulbactam, levofloxacin and ciprofloxacin were <30%, and strains from surgical wards had lower sensitivity rates to these drug than those isolated from internal medicine wards (χ2 =4.987, 4.575 and 5.359, P<0.05).The sensitivity rates of Klebsiella pneumonia isolated from internal medicine wards to ceftazidime , gentamicin and aztreonam were 68.8%, 60.6% and 69.7%, which were higher than those isolated from surgical wards (36.0%, 32.0%, and 40.0%), and the differences were of statistical significance (χ2 =6.068,4.661 and 5.115, P<0.05).Pseudomonas aeruginosa strains were highly sensitive to piperacillin/tazobactam and amikacin, and the susceptibilities of strains isolated from surgical wards (98.4%and 96.8%) were higher than those isolated from internal medicine wards (75.0% and 81.3%) (χ2 =11.797 and 5.221, P <0.05). Pseudomonas aeruginosa strains isolated from surgical wards were also highly sensitive to cefepime (92.1%), but the sensitive rate of strains from internal medicine wards was only 37.5%, and the difference was of statistical significance (χ2 =24.696, P<0.01).Enterococcus faecium and Enterococcus faecalis were sensitive to tigecycline , vancomycin and linezolid with the sensitivity rates over 95%.Except quinupristin/dalfopristin and tetracycline , the sensitivities of Enterococcus faecalis to other antibiotics were higher than Enterococcus faecium.Susceptibility of Enterococcus faecium from surgical wards (33.3%) to moxifloxacin was lower than those from internal medicine wards (70.8%), and the difference was of statistical significance (χ2 =4.629, P <0.05).Conclusion There are differences in distribution and antimicrobial susceptibility of pathogens isolated from internal medicine wards and from surgical wards .

Objective To investigate the influence of combined irbesartan/hydrochlomthiazide on morning blood pressure surge(MBPS)and left ventricular mass(LVM) in essential hypertension.Methods After 4-8 weeks' run-in period,if blood pressure wagn't up to the standard,the 120 patients were given irbesartan/hydrochlorothiazide once daily from 150 mg/12.5 mg for 12 months to 300 mg/25mg for another 12 months.MBPS was conducted by arnbuhry blood pressure monitoring(ABPM)and LVM was determined by echocardiography at the end of placebo baseline and 12 months later.Results (1)After treatment the patients with MBPS(+)decreased and patients with MBPS(-) increased.(2)After treatment the extents of MBPS were reduced in MBPS(+)patients[systolic blood pressure(SBP)difference(16.1±1.8)mm Hg(1mm Hg=0.133 kPa)vs(29.4±2.8)mm Hg,diastolic blood pressure(DBP)difference(10.2±2.3)mm Hg vs(21.2±2.2)mm Hg,P<0.01]with little change in MBPS(-)patients[SBP difference(11.2±2.4)mm Hg vs(10.1±1.2)mm Hg,DBP difference(5.9±1.9)mm Hg vs(6.8±3.2)mm Hg]compared with before treatment.(3)LVM indexes of all patients were significantly reduced.Conclusion Irbesartan/hydrochlorothiazide can effectively attenuate the extent of MBPS, and has advantages on reversing left ventricular hypertrophy.

ObjectiveTo observe the prevalence of deep venous thrombosis(DVT) of lower extremities after acute stroke. MethodsDetection by ultrasonogaphy of bilateral lower extremities was taken in inpatients with stroke within 72 hours 4 days and 14 days after stroke, in order to determine the morbidity of DVT. ResultsThe morbidity of DVT of lower extremities was 7.9%. DVT could be found 4 days after stroke, but the majority of cases were found out 14 days after stroke. DVT mainly affected the paralytic limb, but some of them could involve bilateral limbs.ConclusionDVT of lower extremities could develop at the early stage of stroke. It is necessary to utilize the prophylactic methods to reduce its harmfulness as early as possible.

Objective To evaluate the value of the short-segment nerve conduction studies (SSCSs, inching test) in the diagnosis and localization of cubital tunnel syndrome (CubTS).Methods The clinical and electrophysiologic data of 46 patients (92 limbs from 32 men and 14 women, aged from 19 to 59 years, with average age of 41.2 years) with CubTS were collected.The symptoms occurred in unilateral arm in 41 patients and bilateral arms in 5 patients, involving 35 left arms and 16 right arms.SSCSs were performed in both arms in all the 46 patients.Sixty ulnar nerves were studied in 30 healthy control subjects using SSCSs.Results The 51 symptomatic arms with CubTS were abnormal in long segment motor nerve conduction studies.There were 68 abnormal arms ( 51 symptomatic arms, 17 asymptomatic arms ) in SSCSs.The lesions were located 2 cm proximal to the elbow-the elbow segment ( AE2-E ) in 41 arms (44.6%),the elbow-2 cm distal to the elbow segment (E-BE2) in 23 arms (25%), 4 cm proximal to the elbow-2 cm proximal to the elbow segment (AE4-AE2) in 18 arms (19.6%), 6 cm proximal to the elbow-4 cm proximal to the elbow segment (AE6-AE4) in 9 arms (9.8%), 2 cm distal to the elbow-4 cm distal to the elbow segment (BE2-BE4) in 8 arms(8.6%) and 4 cm distal to the elbow-6 cm distal to the elbow segment (BE4-BE6) in 6 arms(6.5%),respectively.Conclusions SSCSs are more sensitive in detecting CubTS than the conventional long segment motor conduction studies.SSCSs could precisely localize the entrapment lesions in patients with CubTS ,might be a useful tool for the detection of ulnar mononeuropathy at the elbow, especially for diagnosing the patients with CubTS who have no clinical features or have a normal long segmental nerve conduction findings.
