It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".

The advancement of studies about the molecular biology and electronic physiology on sudden cardiac death was summarized in this article, including particularly cardiac concussion(commotio cordis), congenital long QT syndrome, and Brugada syndrome which probably resulting in fatal arrhythmia and sudden cardiac death. These corpses of fatal functional disorders often show the results of negative autopsy without obvious organic pathological changes. So when come across negative autopsy the medical examiner and the pathologist should be careful to investigate the inductive cause of sudden death, the history of disease, and the family history, then to rule out the possibility of the above disorders.

OBJECTIVETo establish a model of immature rat hypoxic-ischemic brain damage (HIBD) which was expected to be similar to periventricular leukomalacia in human preterm infants pathologically and neuroethologically, and to investigate the role of minocycline (MN) in this model.

METHODTotally 192 Sprague-Dawley rats (postnatal day 2, P(2)), of either sex, were randomly divided into 4 groups: normal-group, sham operation group, HIBD-group, HIBD + MN group, each group had 48 rats. HIBD group and HIBD + MN group survived the left common carotid artery (CCA) ligation followed by 4h exposure to 8% O(2). Rats in sham operation group only survived the left CCA isolation. Rats in normal group were not treated with anything. In HIBD + MN group, the rats were treated with intraperitoneal injection of minocycline 45 mg/kg, immediately after HI and every 24 h for 2 days. Brain tissues were collected on day 3, 1 week, 2 weeks, 4 weeks after HI, for hematoxylin-eosin staining and histological scoring. Frozen sections of the brains were stained with anti-O4, anti-O1 immunohistochemistry on day 3 after HI, and MBP immunohistochemistry 2 weeks after HI. Rats in the four groups underwent neuroethologic examination 4 weeks after HI.

RESULTIn the HIBD group, there were pathological changes in the periventricular white matter. The pathological changes were milder in HIBD + MN group; There was no statistically significant difference between the normal group and HIBD + MN group in the number of positively stained O4 cell (P > 0.05). The number of positively stained O4 cell in the HIBD group was significantly reduced, compared with that of normal group, sham operation group, and HIBD + MN group (23.67 ± 12.00 vs. 52.89 ± 10.68, 39.28 ± 11.78, 41.63 ± 8.41, P < 0.05). The differences in the number of positively stained O1 cell among the normal group, sham operation group, HIBD group and HIBD + MN group had no statistical significance (P = 0.093). The numbers of myelin basic protein (MBP) positively immunostained fiber bundles in the HIBD + MN group were significantly less than that of the normal group and sham operation group (P < 0.05). The numbers of MBP positively immunostained fiber bundles in the HIBD group were significantly less than that of the normal group, sham operation group, and HIBD + MN group (14.71 ± 7.42 vs. 36.67 ± 6.50, 35.50 ± 3.24, 26.33 ± 5.92, P < 0.05). The HIBD group had long-term neuroethologic abnormality. There was no statistically significant difference in the inclined plane test, hanging test and cylinder test among the HIBD + MN group, normal group, and sham operation group (P > 0.05). The scores of the HIBD group had statistical significantly among the normal group, sham operation group and HIBD + MN group (P < 0.05). In the open field test, there was no statistically significant difference between the HIBD group and HIBD + MN group (P = 0.772), but there was significant difference between these two groups and the normal group, sham operation group (P < 0.05).

CONCLUSIONMinocycline protects the pre-oligodendrocyte and has protective effects in terms of long-term neuroethology.

Objective A multicenter, randomized, controlled and open-labled clinical trial was performed to compare the efficacy and safety of recombinant human insulin injection ( Yousilin R) and treated with Yousilin R versus Novolin R for 12 weeks respectively. Results Compared with baseline,the levels of glycosylated hemoglobin A1c ( HbA1c ) at the end of 12 weeks treatment decreased from 10. 77% to 7. 72% ( P ＜0. 05 ) in Yousilin R group and from 10. 33% to 7. 62% ( P ＜0. 05 ) in Novolin R group,2-hour postprandial plasma glucose ( 2hPG ) decreased from 15.49 mmol/L to 9. 72 mmol/L ( P ＜ 0. 05 ) in Yousilin R group and from 15.33 mmol/L to 10. 07 mmol/L( P ＜ 0. 05 ) in Novolin R group, and fasting plasma glucose (FPG) decreased from 10. 90 mmol/L to 7. 31 mmol/L( P ＜0. 05 ) in Yousilin R group and from 10. 22 mmol/L to 7.21 mmol/L (P ＜0. 05) in Novolin R group. The changes of HbA1c, 2hPG and FPG from baseline to endpoint in Yousilin R group was similar to those in Novolin R group ( P ＞ 0. 05 ).Furthermore, hypoglycemic events(26. 42% vs 30. 48% ), other adverse events( 13.21%vs 16. 19% ) ,and serious adverse events( 1.89%vs 1.90% )were comparable between Yousilin R and Novolin R groups(P ＞0. 05 ). Conclusions Yousilin R has similar efficacy, safety and compliance profiles to Novolin R group in the treatment of diabetic patients.

OBJECTIVEImpulse oscillometry (IOS) is a novel technique for the evaluation of pulmonary function. Soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) are definitive indicators for the severity of asthma. This study aimed to explore the relationship of IOS pulmonary function with sICAM-1 and sVCAM-1, and their values in childhood asthma.

METHODSIOS via Master Screen System for pulmonary function was performed in 40 children with acute asthma and 25 healthy children. Twenty-three of 40 children with acute asthma were re-tested for IOS pulmonary function at remission. sICAM-1 and sVCAM-1 levels were measured in 23 children with acute asthma, 20 asthmatic children at remission and 16 healthy children.

RESULTSThe parameters of IOS pulmonary function, R5, R20, R5-R20, X5, Fres and Zrs in children with acute asthma were significantly higher than in asthmatic children at remission and in normal controls (q= 2.91-15.61, P < 0.01 or 0.05). There were significant differences in R5, R5-R20, Fres and Zrs between the asthmatic children at remission and normal controls (q= 3.08- 9.19, P < 0.01 or 0.05). sICAM-1 and sVCAM-1 levels in children with acute asthma were significantly higher than in asthmatic children at remission and in normal controls (q= 6.23-26.15, P < 0.01). The asthmatic children at remission had higher levels of sICAM-1 and sVCAM-1 than the normal controls (q=16.86, 12.46, P < 0.01). R5-R20 positively correlated with sICAM-1 and sVCAM-1 in children with acute asthma (r=0.45, 0.57, P <0.05).

CONCLUSIONSIOS for pulmonary function and sICAM-1 and sVCAM-1 may be used to evaluate the severity and therapeutic effects of childhood asthma. A correlation exists between IOS pulmonary function and sICAM-1 and sVCAM-1.

OBJECTIVETo evaluate chest radiographic findings of children with 2009 influenza (H1N1) virus infection.

METHODData of 235 patients who had microbiologically confirmed H1N1 infection and available chest radiograph obtained between May 1(st) 2009 and Jan. 31(st) 2010 were retrospectively analyzed. The final study group was divided on the basis of clinical course [group 1 mild, outpatients without hospitalization (n = 172); group 2 moderate, inpatients with brief hospitalization (n = 49); group 3 severe, ICU admission (n = 14)]. Four pediatric radiologists reviewed all the chest radiographs of lung parenchyma, airway, pleural abnormalities and also anatomic distribution of the disease.

RESULTNo significant sex or age differences were found among the study groups (P > 0.05). The mean interval between the onset of clinical symptom and the initial chest radiography was (5.91 ± 1.64) days (group 1), (3.60 ± 1.43) days (group 2) and (1.21 ± 0.41) days (group 3), respectively. The differences among the three groups were significant statistically (χ(2) = 13.368, P < 0.01). The ratio of abnormality presented at initial chest X-ray was 79.7% in group 1, 91.8% in group 2 and 100% in group 3. Radiographically, there were prominent peribronchial markings (group 1, 55.2%; group 2, 83.7%; and group 3, 78.6%), consolidation (group 1, 34.3%; group 2, 69.4%; and group 3, 100.0%), hyperinflation (group 1, 22.1%; group 2, 44.9%; and group 3, 50.0%) and ground glass opacity (group 1, 0.6%; group 2, 2.0%; and group 3, 14.3%) in the chest radiographs. The differences of presenting were statistically significant (P < 0.01). In the severe group, the lesions distributed diffusely and asymmetrically with multi-lobe involvements.

CONCLUSIONIn children with 2009 influenza A H1N1 viral infection, the interval between the onset of clinical symptom and initial chest radiography, the ratio of abnormality presented at initial chest X-ray film and the severity of chest film are parallel to their clinical situation.

Objective To determine factors influencing the immunization of measles vaccine(MV) among health care workers in Hangzhou, and to provide recommendations to promote their MV immunization. Methods In 2016, we used typical sampling method to select 2 general hospitals of 3 different levels, 1 infectious diseases hospital and 1 children's hospital, and interviewed health care workers in high and low measles risk departments to investigate their MV immunization by using a structured questionnaire. Factors influencing their immunization were analyzed by logistic regression model. Results A total of 141 of 349 health care workers investigated had MV immunization history, and the MV immunization coverage rate was 40.40%.The logistic regression analysis showed that working in low measles risk department(OR=1.91, 95%CI: 1.20-3.04) was risk factors for MV immunization, and having confidence with the effectiveness of MV(OR=0.40, 95%CI: 0.21-0.78) . Knowing the "measles vaccination suggestion" (OR=0.50, 95%CI: 0.28-0.91) and the hospital had organized measles vaccination for health care workers in recent years(OR=0.35, 95%CI: 0.22-0.57) were protective factors for MV immunization. Conclusions Health care workers in Hangzhou had low MV coverage but high willingness. We should enhance education activity of MV immunization and organize measles vaccination for health care worker at regular intervals by hospitals to increase the MV coverage.

OBJECTIVETo clone the genes encoding the structural proteins VP1-VP4 of enterovirus 71 and investigate the immunogenicity of the expressed recombinant proteins.

METHODSThe VP1-VP4 cDNAs were amplified by RT-PCR from the extracted viral RNA and cloned into pMD19-T vector. The cloned VP1-VP4 genes were then inserted into the multi-cloning sites of plasmid pQE30a and expressed in E. coli M15 with IPTG induction. After washing with 8 mol/L urea and purification with Ni-affinity chromatography, the recombinant proteins obtained were tested for immunogenicity by Western blotting and ELISA using rabbit antisera against enterovirus 71 and Coxsackie Virus A16.

RESULTSThe recombinant VP1-VP4 proteins were highly expressed in E. coli M15 and the purified proteins could be specifically recognized by the rabbit sera against enterovirus 71.

CONCLUSIONThe expressed enterovirus 71 structural proteins show good immunogenicity and can be used for developing enterovirus 71 vaccine and detection kits.

OBJECTIVETo produce neutralizing antibodies against envelope protein domain III (EDIII) of dengue virus serotype I (DENV-1) and evaluate the nonstructural protein 1 (NS1) antigen capture enzyme-linked immunosorbent assay (ELISA) for identification of antibody neutralizing abilities.

METHODSFive BALB/c mice and one New Zealand Rabbit were immunized with recombinant EDIII protein of DENV-1 for the production of hybridomas and hyperimmune sera. Indirect ELISA, immunofluorescence assay (IFA) and Western Blot analyses were applied to identify specificity of antibodies. Comparing to plaque reduction neutralization test (PRNT), the new established DENV-1 specific NS1 antigen capture ELISA was used for detecting the neutralizing abilities of these antibody.

RESULTSFour strains of monoclonal antibodies (mAbs) named 1A1, 1B3, 3D3 and 9D6 and one hyperimmune serum of rabbit were obtained, all of which were approved to have neutralizing abilities to DENV-1 with the PRNT titer of 1:1024, 1:512, 1:256, 1:4096 and 1:4096. MAb 3D3 with the lowest neutralization titer in PRNT had not shown neutralizing ability to DENV-1 in NS1 antigen capture ELISA, while MAbs 1A1, 1B3 and 9D6 and the rabbit hyperimmune serum could protect the C6/36 from being infected by DENV-1 with the neutralization titer of 1:32, 1:32, 1:128 and 1:128 in this assay.

CONCLUSIONNS1 antigen capture ELISA could be used to identify antibody neutralizing abilities to DENV, it was a faster and more convenient way to screen antibodies with high neutralization titer and might also be used as one of the methods to evaluate the effects of vaccines.
