Trend of disease spectrum of hospitalized children in Anhui provincial children’s hospital from 2013 to 2017 / 中华疾病控制杂志

@# Objective To investigate the composition of the disease spectrum of hospitalized children in Anhui Provincial Children's Hospital, so as to provide scientific basis of the strategy to refine pediatric medical resources and health care. Methods Totally 268809 patients from 2013 to 2017 was analyzed and compared with the 2003-2007 data. Results Compared to 2003-2007, the number of hospitalized children and involved diseases increased significantly in 2013-2017. The proportion of common diseases such as respiratory system (28.73% vs 26.49%), digestive system (12.68% vs 10.78%), and nervous system (6.22% vs 3.72%)) significantly decreased; while the proportion of injury and poisoning (2.13% vs 7.4%), infectious diseases, parasites (7.15% vs 10.69%), tumors (2.65% vs 4.12%), and blood immunity (1.42% vs 3.19%) increased. Respiratory diseases remain the first ranking disease in hospitalized children (26.49%), with pneumonia as the first ranking single disease among it. The top 5 hospitalized children in 2013-2017 were pneumonia, bronchitis, hernia, respiratory infections, and neonatal pneumonia. Conclusions The absolute number and capacity of services have been greatly improved in the hospital. While constantly improving the level of diagnosis and treatment of common diseases, we should pay more attention to the injury poisoning, mental and behavioral diseases and infectious diseases in children.

A simple skin flap plasty to repair tracheocutaneous fistula after tracheotomy / 中华创伤杂志(英文版)

The tracheocutaneous fistula after tracheostomy is a complex clinical problem. An ideal fistula closure is still difficult at present though a variety of fistula-closing methods have been reported in the literature. We used a turnover skin flap to cover the fistula. All the procedures were completed at bedside under local anesthesia. The fistula was successfully closed and well healed without complications within 7-9 days. It has been proven that this operation is simple, effective, and safe.

Adenosine Al Receptor Mediated Neuroprotection of Shenmai Injection on Rat Cerebral Ischemia/Reperfusion Injury: an Experimental Study / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe whether adenosine Al receptor (Al R) mediated neuroprotection of Shenmai Injection (SI) on rat cerebral ischemia/reperfusion (I/R) injury.</p><p><b>METHODS</b>The focal cerebral I/R model was established by middle cerebral artery occlusion (MCAO). Totally 60 successfully modeled rats was divided into 5 groups according to randomized block principle, i.e., the model group, the SI group, the SI + AlR antagonist (1,3-dipropyl-8-cyclopentylxanthine, DPCPX) group, the AlR antagonist control group, and the dimethyl sulfoxide (DMSO) control group, 12 in each group. Besides, a sham-operation group was set up (n =12). SI at 15 mL/kg was peritoneally injected to mice in the SI group immediately after cerebral I/R. Equal volume of normal saline was injected to mice in the model group and the sham-operation group. DPCPX at 1 mg/mL was peritoneally injected to mice in the Al R antagonist control group 30 min before peritoneal injecting SI. DPCPX at 1 mg/kg and DMSO at 1 mL/kg were peritoneally injected to mice in the AlR antagonist control group and the DMSO control group 30 min immediately before cerebral I/R. Rats' neurobehavioral scores were assessed after 24 h reperfusion. The volume of cerebral infarction and Bcl-2 protein expression of cerebral infarction penumbra were also detected. Results Compared with the sham-operation group, neurobehavioral scores, the volume of cerebral infarction, and Bcl-2 protein expression increased (all P <0. 05). Compared with the model group, neurobehavioral scores and the volume of cerebral infarction obviously decreased, but Bcl-2 protein expression increased in the SI group (all P <0. 05). Compared with the SI group, neurobehavioral scores increased, the volume of cerebral infarction was obviously enlarged, and Bcl-2 protein expression was obviously reduced in the A1R antagonist control group (all P <0. 05).</p><p><b>CONCLUSIONS</b>SI's neurobehavioral scores could be partially reversed in the Al R antagonist control group, the volume of cerebral infarction and Bcl-2 protein expression improved. AlR might possibly meditate neuroprotection of SI on MACO mire</p>

Clinical significance of peripheral blood neutrophil CD64 in Kawasaki disease / 中华实用儿科临床杂志

Objective To investigate the expression level of peripheral blood neutrophil CD64 in Kawasaki disease (KD),and explore its clinical significance.Methods Fifty-four patients with KD were divided into 2 groups [13 patients with coronary artery lesions(CAL) and 41 patients without CAL],and 30 age-matched patients with sepsis and 10 healthy children were studied.The levels of peripheral blood neutrophil CD64 was measured by flow cytometry.Results Before treatment,the levels of C D64 in children with KD(7.02 ± 3.21)and sepsis (11.25 ± 5.14) were significantly higher than the healthy children (2.45 ± 0.52),and the level of CD64 in the KD group was significantly lower than that in sepsis group(P ＜ 0.01).CD64 index were significantly elevated in the 2 groups of KD patients before treatment (CAL group:5.74 ± 3.09 ; without CAL:7.43-± 3.17).There was no significant difference in the CD64 level between KD patients with CAL and without CAL.CD64 index in the 2 groups of KD patients after treatment (CAL group:2.56 ± 0.73 ; without CAL:2.63-± 0.69) were significantly lower than those before treatment (all P ＜ 0.01).Conclusions The expression of peripheral blood neutrophil CD64 in KD is significantly elevated.The degree of elevation in CD64 possibly has clinical meaning in differentiating KD from sepsis,and it can be a sensitive factor of disease outcome.

ShRNA-mediated silencing of MDM2 inhibits growth of HepG2 hepatocellular carcinoma cells xenografted in nude mice / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To construct a short hairpin (sh)RNA targeting the gene encoding the MDM2 oncoprotein in order to investigate its role in human hepatocellular carcinoma (HCC) and its potential for use as a gene therapy strategy to inhibit HCC growth in vivo.</p><p><b>METHODS</b>Small interfering (si)RNAs were designed targeting the MDM2 gene (siMDM2-1 and siMDM2-2) and unrelated sequences (negative control) and cloned into the expression plasmid pGCSilencer-U6-neo-GFP. A HCC mouse model was established by subcutaneous inoculation of HepG2 cells (2 x 10(6) in 0.2 ml) into 20 nude mice. The inoculated mice were divided into four equal groups for tumor-localized injections of saline, negative control siRNA plasmid, siMDM2-1 plasmid, and siMDM2-2 plasmid. Tumor growth was observed daily (by caliper measurement) for one month, when mice were sacrificed by cervical dislocation. The tumor mass was resected for analysis of tumor inhibition rate (% = [(average tumor weight of control group - average tumor weight of treatment group) / average tumor weight of control group x 100]) and effects on MDM2 and p53 mRNA and protein expression (by reverse transcription- PCR and western blotting, both normalized to beta-actin). Significance of between-group differences was assessed by one-way ANOVA or LSD test; pairwise comparisons were made by the Chi-squared test.</p><p><b>RESULTS</b>siMDM2-1 and siMDM2-2 suppressed the xenografted tumor growth remarkably (60.6% and 54.6% inhibition rates, respectively), significantly reduced the expression ofMDM2 gene (62.8% and 61.6%) and protein (60.7% and 59.5%), and significantly increased p53 gene (47.1% and 45.6%) and protein (45.9% and 44.3%) (all, P < 0.05).</p><p><b>CONCLUSION</b>shRNA-mediated silencing of the MDM2 gene effectively inhibits HCC tumorigenesis of subcutaneously xenografted HepG2 cells in nude mice, and the mechanism may involve p53.</p>

Objective To investigate effects of ginkgo biloba extract(GBE) and tanshinoneⅡ A preventative administration against cerebral ischemia and reperfusion injury in gerbils.Methods Cerebral iscthemia and reperfu- sion injury were made by 10 minutes'occlusion of bilateral carotid arteries followed by 24 hours' reperfusion in ger- bils.GBE,tanshinone Ⅱ A,nimodipine or GBE plus tanshinone Ⅱ A were administrated intragastrically 3 days prior to and at the day of ischemia and reperfusion.Effects of experimental agents on mortality,stroke index,brain body index,water content in brain hemisphere,level of SOD activity and MDA in cerebral tissue were measured,and pathological changes of cortex and hippoearnpal CA1 sector were observed.Results GBE 48 mg/kg and tanshinone Ⅱ A 25mg/kg preventive administration could significantly reduce the stroke index,brain body index,and water in brain hemisphere,together with a reduced mortality of cerebral ischemia and reperfusion injuried gerbils.The two a- gents could also significantly improve the activity of SOD,reduce the level of MDA in cerebral tissue and the injury in cortex and hippocampal CA1 sector.Moreover,combined treatment of these two agents demonstrated more signifi- cant effects.Conclusion GBE,tanshinone Ⅱ A and combined therapy of these two agents may protect cerebral func- tion from ischemia and reperfusion injury through reducing the cerebral edema and attenuating the injury of oxygen free radicals.

Construction of the DNA vaccine of major outer membrane protein of Neisseria gonorrhoeae and investigation of immune effects after vaccination / 中华预防医学杂志

<p><b>OBJECTIVE</b>To clone PIB gene of Neisseria gonorrhoeae, and to construct a recombinant eukaryotic expression vector pCI-PIB and to understand the effects of pCI-PIB vaccination in mice to induce specific humoral and cellular immune responses.</p><p><b>METHODS</b>The entire PIB gene of Neisseria gonorrhoeae (960 bp) was amplified by using PCR. An eukaryotic eukaryotic vector pCI-PIB was then constructed. BALB/c mice (n = 65, 100 microg/time/mouse) were immunized with pCI-PIB by intramuscular injection. ABC assay was employed to examine the PIB expression in muscular cells of the pCI-PIB-immunized mice (n = 10). ELISA and MTT assays were used to measure the effects of humoral and cellular immune responses of the remaining pCI-PIB-immunized mice. By using slide agglutination test and complement bacteriolytic test, the serum anti-bacterial activity of the pCI-PIB immunized mice was determined.</p><p><b>RESULTS</b>The entire PIB gene amplification fragment of the expected size (960 bp) was successfully obtained by PCR. In comparison with the reported PIB gene sequence (GenBank No: AF090801), the homology of nucleotide sequence of the target inserted fragment in the recombinant plasmid pCI-PIB was as high as 99.28%. The muscular cells of the immunized mice could take in pCI-PIB and then express PIB. In the pCI-PIB immunized mice, the higher titer (1:4000) of specific serum IgG and the specific T lymphocyte response were found. The proliferation index (4.031) was significantly higher than that of the controls (1.127) (t = 71.71, P < 0.05). The sera and washings from the pCI-PIB immunized mice could agglutinate Neisseria gonorrhoeae and kill this microbe in presence of complements.</p><p><b>CONCLUSION</b>In this study we successfully constructed a recombinant eukaryotic expression vector pCI-PIB. The mice inoculated with pCI-PIB might efficiently produce the specific humoral and cellular immune responses, suggesting that pCI-PIB should be potential service as a candidate of Neisseria gonorrhoeae DNA vaccines.</p>
