1.Necrotizing pneumonia in children
Journal of Clinical Pediatrics 2013;(8):701-705
Necrotizing pneumonia is a severe complication of community-acquired pneumonia in children, with no clear deif-nition currently, characterized by parenchymal injury, necrosis and cavity formation. Streptococcus pneumonia is the most common pathogen;however a positive microbiology is not always obtainable. The clinical manifestation of necrotizing pneumonia is more seri-ous than ordinary pneumonia, and complications are common. Chest CT scan is helpful to early detection and diagnosis. Antibio-tics remain the mainstay of treatment, and the prognosis is relatively well.
2.Effect of acupuncture Zusanli on brain functional magnetic resonance imaging
Chinese Journal of Primary Medicine and Pharmacy 2017;24(19):2963-2967
Objective To study the effect of acupuncture Zusanli on brain functional magnetic resonance imaging.Methods 96 healthy volunteers were randomly divided into acupoint group and non-acupoint group.The acupoint group received acupuncture Zusanli,and the non-acupoint group received manipulation,acupuncture and sham acupuncture.The functional brain imaging was determined by MRI,the brain functional images were compared between two groups.Results All subjects were matched with the end of the experiment,the acupoint group received acupoint stimulation,had obvious needling sensation,the non-acupoint group had mild needling sensation.The acupoint group activated 13 brain regions,non-acupoint group in 10 brain regions,the thalamus,pons,supramarginal gyrus in non-acupoint group without the activation.In the basal ganglia (28 cases vs.5cases) and temporal lobe (38cases vs.21cases) between the two groups were activated,the difference was statistically significant(x2 =36.250,P < 0.05).In the temporal lobe,the left hemisphere response rate(73.68%) was significantly higher than the right hemisphere (36.84%),the difference was statistically significant (x2 =8.265,P < 0.05).In the basal ganglia,left hemisphere activation (67.86%) was higher than that of the right hemisphere(42.86%),but the difference was not statistically significant (x2 =0.724,P > 0.05).Conclusion The research of acupuncture by brain functional magnetic resonance imaging showed that Zusanli acupoint can activate the brain function area through brain regulation and treatment of body organs,so as to prove the existence of its own and meridian sensing characteristics.
4. Preparation, identification and application of polyclonal antibodies against human PIWIL2 protein
Academic Journal of Second Military Medical University 2010;29(9):1034-1037
Objective: To prepare rabbit polyclonal antibody against human P-element-induced wimpy testis like 2 (HIWI2) protein, identify its properties and investigate its distribution in normal and tumor tissues by means of tissue chip. Methods: PIWIL2 peptide was synthesized chemically and conjugated to Keyhole limpet hemocyanin (KLH) as an immunogen. Then the PIWIL2-KLH conjugation was injected into rabbits subcutaneously to produce polyclonal antibodies. The specificity and sensitivity of antibodies were identified by ELISA and Western blotting after purification by affinity chromatography. PIWIL2 was then immuno-stained on the tissue chip to study its distribution in the normal and tumor tissues. Results: Rabbit's antibodies against human PIWIL2 were prepared after the injection of PIWIL2-KLH conjugation subcutaneously. These antibodies were identified as PIWIL2 peptides by ELISA and Western blotting assay. PIWIL2 protein expression was tissue-specific in tumor tissues, with PIWIL2 protein found in the cytoplasm of smooth muscle cells of most normal and tumor tissues. Conclusion: The polyclonal antibodies against human PIWIL2 protein have been successfully prepared, which provides a basis for further study on the role of PIWIL2 in the pathway of miRNA/RNA.
6.Risks and benefits: new concepts of treatment of late-onset hypogonadism.
National Journal of Andrology 2014;20(6):483-489
Late-onset hypogonadism (LOH) is a clinical and bio-chemical syndrome associated with advancing age in males and seriously affects the quality of life of some of the patients. A classical therapeutic option for LOH is testosterone supplementary treatment (TST). Its effectiveness has been verified, whereas its long-term safety remains to be further evaluated. With deeper insights into LOH, many new therapeutic strategies have been proposed, which include the treatments with gonadotropins, testosterone precursors (such as dehydroepiandrosterone [DHEA]), non-aromatizable androgens (such as dihydrotestosterone [DHT]), antiestrogens (such as aromatase inhibitors and estrogen receptor antagonists), and Chinese medicine. Meanwhile, studies on the transplantation of Leydig stem cells, selective androgen receptor modulators (SARMs), and selective estrogen receptor beta (ERbeta) agonists have shed new light on the treatment of LOH.

Objective To observe the expression of neuroglobin (Ngb) in cerebral cortex of traumatic brain injury rats, and investigate the role of neuroglobin in brain injuries. Methods A traumatic brain injury rat model was constructed with Feeney's method. Fifiteen experiment animals were divided randomly into normal control group, 12h-post-trauma group and 36h-post-trauma group (5 each). Immunohistochemistry and image analysis techniques were used to measure the area, optic density (OD) value and integrated optic density (IOD) value of Ngb immunoreactive products in primary somatosensory cortex (S1) and retrosplenial granular b cortex (RSGb), which was located in the inner side and out side of traumatic brain injury cavity in coronal section of rat brain respectively. Results Ngb immunoreactive products were significantly increased after brain trauma, especially in 36h-post-trauma group. The image analysis showed that there was no significant difference of immunoreactive product area in the 3 groups (P

Objective To investigate the significance of MRI T2 fluid-attenuated inversion recovery hyperintense vessel sign (FLAIR HVS)in clinical prognosis evaluation of the patients with acute middle cerebral artery irnfarction.Methods The data in 57 inpatients with acute middle cerebral artery infarction in our hospital from Aug.2013 to Aug.2015 were retrospectively analyzed.All cases were performed the intact MRI examination(ineluding FLAIR,DWI and MRA)and CTA.The infarct volume with DWI,national institute of health stroke scale(NIHSS)score and modified Rankin Scale(mRS)score on 30 d after discharge were performed the comparative analysis.Results Fifty-seven cases of middle cerebral artery occlusion were divided into the distal HVSgroup and non-distal HVS group(8 cases in proximal HVS group,21 cases in HVS negative group).The infarction volume of DWI sequence,NIHSS scores at admissiom and discharge and mRS score on 30 d after discharge in the distal HVS group were superior to those in the non-distal HVS group(P<0.05).Conclusion MRI-T2 FLAIR sequence HVS has certain reference value in the prognosis evaluation in the patients with middle cerebral artery occlusion.
