Journal of Chinese Physician 2016;18(1):148-150
Modern perinatal and neonatal medical advances make the survival rate of extremely low birth weight infants(ELBWI) higher,but its neurodevelopmental impairment,growth stasis and health status are poor.The survival rate of our county is lower than that of developed countries.In China,there are a few reports on neurodevelopment injury of ELBWI.This review will summarize prevention and prognosis on neurodevelopmental of ELBWI.
2.The clinical analysis of Compound Erlongzuoci pill combined with auricular point stickingand vitamin B12 acupoint injection therapy on nervous tinnitus of middle and old aged
Chinese Journal of Biochemical Pharmaceutics 2017;37(7):131-133
Objective To explore the clinical analysis of Compound Erlongzuoci pill combined with auricular point stickingand vitamin B12 acupoint injection therapy on nervous tinnitus of middle and old aged.Methods 80 cases of middle and old aged patients with neurogenic tinnitus treated in our hospital from November 2015 to November 2016 were selected and randomly divided into the control group and the observation group, 40 cases of patients in each group, the control group was given Auricular Pressure Combined with vitamin B12 acupoint injection, the observation group was treated with Compound Erlongzuoci pills combined with auricular point sticking therapy and vitamin B12 acupoint injection,The clinical therapeutic effect of two groups, the tinnitus severity score of patients before and after treatment, the changes of tinnitus loudness and different frequency thresholds were compared between the two groups.Results The total effective rate of the clinical observation group was significantly higher than that of the control group, the difference between the two groups was statistically significant(P<0.05).Before treatment, there is no significant difference between tinnitus severity score, tinnitus loudness and hearing threshold between the two groups,the indexes after treatment in two groups were significantly improved(P<0.05), and the observation group tinnitus severity score, tinnitus loudness and different frequency thresholds were significantly lower than the control group, the difference was statistically significant(P<0.05).Conclusion Compound Erlongzuoci pill combined with auricular senile nervous tinnitus pressure and vitamin B12 acupoint injection therapy can significantly improve the degree of tinnitus patients, the clinical effect is confirmed.
3.Macrofollicular variant of papillary thyroid carcinoma:report of 2 cases and literature review
Journal of Endocrine Surgery 2014;(4):282-285
Objective To discuss the pathological morphological features of the macrofollicular variant of papillary thyroid carcinoma ( MFPTC ) .Methods Clinical data of 2 cases of MFPTC were reviewed .The his-topathological and immunohistochemical features were analyzed .Relevant literatures were reviewed .Results The histological characters of MFPTC mainly included its multiple macrofolliculus , plenty of colloid and atypical nuclear morphology.Immunohistochemistry stain showed cytokeratin-19, Galectin-3 and HBME-1 expressed simultaneously. Conclusions MFPTC is a thyroid papillary carcinoma with unique histological characters .It should be differen-tially diagnosed from some benign lesions such as nodular goiter and follicular adenoma .Immunohistochemical stain of cytokeratin-19, Galection-3 and HBME-1 may be very helpful in the diagnosis and differential diagnosis .
4.Ampelopsin induces apoptosis via altering expression of Bcl-2/Bax and activating caspase-3 in human hepatoma cell line Bel-7402
Chinese Pharmacological Bulletin 2003;0(11):-
Aim To investigate the effects of ampelopsin on induction of apoptosis in human hepatocellular carcinoma Bel-7402 cells.Methods Bel-7402 cells were treated with ampelopsin with different concentrations for 24,48 and 72 h.The cell proliferation was detected by MTT assay.The morphological change of cells was observed through microscope observation by fluorescence staining.DNA fragmentation was visualized by agarose gel electrophoresis.The apoptosis rate was analyzed by flow cytometry.The expressions of caspase-3,Bcl-2 and Bax protein were detected by Western blot.Results Ampelopsin inhibited the proliferation of Bel-7402 cell line in a dose-and time-dependent manner.The IC50 values were 89.6?16.1,36.2?6.5 and 15.3?3.0 mg?L-1 at 24,48 and 72 h,respectively.The fluorescence microscope showed clearly cell apoptosis with apoptotic body.Agarose gel electrophoresis result showed that Bel-7402 treated with ampelopsin produced a DNA ladder band.The sub-G1 peak was detected and resulted in dose-and time-dependent increasing of the population of sub-G1 DNA content by flow cytometry.The expression of Bcl-2 protein was down-regulated,while the expression of Bax protein was up-regulated.The pro-caspase-3 protein was down-expressed and activated.Conclusions Ampelopsin could inhibit Bel-7402 proliferation through inducing cell apoptosis.The mechanism might be that ampelopsin could directly or indirectly enhance the level of anti-apoptosis protein Bcl-2 and decrease the level of apoptosis protein Bax.The pathway of pro-caspase-3 activated was initiated and effector caspase-3 was sequentially activated.
5.The effects of atorvastatin on the cardiomyocyte apoptosis induced by acute myocardial infarction in rats
Journal of Chinese Physician 2011;02(z2):27-29
ObjectiveTo investigate the effects of atorvastatin on cardiomyocyte apoptosis and caspase-3 expression in acute myocardial infarction in rats.MethodsFifty SD rats were randomly divided into 3 group:sham group,control group( normal saline),atorvastatin pretreatment group ( 10mg/kg),The atorvastatin group were pretreated with atorvastatin ( 10mg/kg ) for 3 days,and those in the control group were pretreated with normal saline instead.All rats underwent coronary ligation of left anterior descending branch to establish AMI rat s model on the fourth day except the sham group,while sham group only received thoracotomy without coronary ligation.Then,The infarct size area at risk were defined by Evans blue and TTC staining,the caspase-3 mRNA expression of myocardium was measured with reverse-transcriptase polymerase chain reaction(RT-PCR) and the apoptosis index was analyzed by TUNEL staining.Results Compared with control group,the infarct size,the caspase-3 mRNA expression of myocardium,the apoptotic index were decreased significant in the atorvastatin group ( P < 0.05 ).ConclusionPretreatment with atorvastatin has protective effect on the acute ischemic cardiomyocytes,which may probably be associated with the reduction of the expression of caspase-3 mRNA in the myocardium and the apoptotic index.
6.Network of multiple factors and cascades: hotspots of mechanism studies for diabetic retinopathy
Chinese Journal of Ocular Fundus Diseases 2013;(1):5-8
The pathogenesis of diabetic retinopathy is complicated.The vast network of multiple factors including unifying mechanism,inflammatory reaction,neuron degeneration and metabolic memory of glucose,and the four established pathogenic molecular pathways are hotspots of mechanism research for diabetic retinopathy.Nevertheless,these researches may be only one corner of the iceberg of DR mechanism,and we still face enormous challenges in DR mechanism research.Collaboration with multiple disciplines to study the relationship between DR and diabetes and other systemic diseases,search novel therapy targets may increase the result in an unexpected windfall for DR basic research.

8.Characteristics and functions of microglia:Advances in studies
Journal of Medical Postgraduates 2017;30(2):216-219
Microglia are functionally principal immune effector cells widely spread in the central nervous system ( CNS) and physiological play a role in monitoring and stabilizing the internal environment. Very sensitive to external stimulation, microglia are eas-ily activated by slight pathological changes in the CNS. The activated microglia, on the one hand, phagocytize cellular debris and ex-crete growth factors to promote nerve repair and, on the other hand, also produce some inflammatory cytokines, glutamate, and nitric oxide, which may aggravate the inflammatory response and lead to secondary injury. This article summarizes the characteristics of mi-croglia and their involvement in CNS diseases and provides a new target for their treatment.
