Objective To discuss the relationship between the expression of programmed death-1 (PD-1) in liver with traditional Chinese medicine (TCM) syndromes and pathological diagnosis in chronic hepatitis B.Methods 156 CHB patients treated in our hospital of infectious diseases department were recruited as an observation group. Based on the principle of informed voluntary and approved by the ethics committee, liver biopsy was adopted to make clear liver tissue pathology. According to TCM classification criteria, CHB patients were divided into five groups: a blood stasis group, a damp heat resistance group, a liver and spleen deficiency group, a liver and kidney yin deficiency group, and a spleen and kidney yang deficiency group. In the same period, 12 healthy persons were recruited as a control group. The PD-1 expression was detected with immunohistochemical SP method, and the correlation between expression of PD-1 in liver tissue and TCM syndrome type and liver pathology was analyzed.Results Different degrees of positive cell expression were found in the liver tissue. With the liver inflammation and fibrosis severity, the number of PD-1 positive cells also increased. The PD-1 expression levels varied with mild, moderate, and severe CHB patients (0.24 ± 0.03, 0.36 ± 0.05 vs. 0.43 ± 0.05) , which were statistically significant (P<0.05) . PD-1 expression levels also varied among different TCM type CHB patients, of which, PD-1 expression of blood stasis type was the highest (0.35 ± 0.04), while the liver and spleen deficiency type was the lowest (0.23 ± 0.03).Conclusion The expression levels of PD-1 has a certain correlation with the patients illness, chronic mechanism, and TCM syndromes. CHB patients can be treated by controlling the expression of PD-1.

5.Effect of beclin1 on vincristine-induced dopaminergic neurons injury in zebrafish.
Acta Pharmaceutica Sinica 2014;49(6):843-848
To investigate vincristine-induced dopaminergic neurons toxicity and mechanism, and explore the molecular target to reduce the toxicity, zebrafish was chosen as a model animal, based on RT-PCR, Western blotting, whole mount in situ immunofluorescence and other technical means. The results showed that the transcription levels of tyrosine hydroxylase gene and dopamine transporter protein gene were inhibited. Furthermore, the number of dopaminergic neurons was decreased by vincristine. Autophagy was suppressed and beclin1 gene expression was inhibited in a dose-dependent manner by vincristine in larval zebrafish. Up-regulated beclin1 partly reduced vincristine-induced neurotoxicity, and down-regulated beclin1 increased toxicity. Beclin1 plays an important role in vincristine-induced dopaminergic neurons toxicity.

Background The ubiquitin-proteasome pathway(UPP)involves 80%-90% degradation of all in- tracellular proteins.Both ubiquitin and rat component 3 of proteasome(RC3)are hence considered to be central me- diators for cell biology.Objective To evaluate the effect of simvastatin on neointimal hyperplasia and the expres- sion of ubiquitin and rat component 3 of proteasome(RC3)after balloon injury in carotid artery.Methods Thirty- two male SD rats were randomly to receive,low dose(0.4 mg/ng,n=8),or moderate(4 mg/ng,n=8),or high- dose(40 mg/ng,n=8)of simvastatin treatment for 28 days.Common carotid aortic artery was injuried rat ballon. The ratio of intima-media(I/M)thickness was determined.The expression level of ubiquitin and RC3 mRNA were assessed by RT-PCR.The expression level of ubiquitin protein was examined with immunohistochemistry. Results Simvastatin inhibited the expression of ubiquitin and RC3 mRNA and ubiquitin protein in dose dependent manner.The intima-media ratio(-50.2 %)and the expression of ubiquitin(-60.3 %)and RC3 mRNA and ubiq- uitin protein(-60.5 %)was reduced by the high dose simvastatin [40 mg/(kg?d)](P

Objective To explore the effect of Da Vinci robot?assisted laparoscopic radical prostatecto?my on the respiratory function of elderly in Intensive Care Units( ICU) . Methods Thirty?nine elderly patients received Da Vinci robot?assisted laparoscopic radical prostatectomy ( RARP ) from January 2015 to April 2016 and 25 cases received conventional laparoscopic radical prostatectomy from January 2014 to December 2014 ad?mitted into ICU were retrospectively analyzed. Their comorbidities,blood loss and transfusion during surgery,ate?rial blood gas(ABG) analysis and respiratory complications after operation,clinical outcomes between the two groups were compared. Results Compared with conventional laparoscopic radical prostatectomy,RARP group spent more time in surgery((4. 23±1. 44) h vs. (3. 25±1. 31) h,t=2. 783,P<0. 05),more patients need venti?lation(11 vs. 1,χ2=4. 378,P<0. 05) . ABG analysis showed respiratory and metabolic acidosis with lower pH (7. 29±0. 09 vs. 7. 35±0. 05,t=3. 886,P<0. 05),HCO3?((20. 05±2. 50) mmol/L vs. (22. 86±2. 53) mmol/L,t=3. 473,P<0. 05),BE(-5. 11±3. 94 vs.-3. 64±1. 17,t=5. 018,P<0. 05) and higher pCO2(46. 15±8. 31 vs. 40. 25±6. 57,t=2. 475,P<0. 05),Lac((3. 54±1. 99) mmol/L vs. (2. 91±1. 39) mmol/L,t=2. 254,P<0. 05) . Conclusion RARP may cause carbon dioxide retention and respiratory complications on elderly pa?tients. It may reduce postoperative respiratory complications by shortening surgery time,lowering pneumoperitone?um pressure,hyperventilation,recruitment maneuvers and chest physical therapy.

Objective To construct and identify the recombinant adenovirus vector containing the Toll-like receptor 2(TLR2) extracellular domain gene of human.Methods Human TLR2 extracellular domain cDNA was amplified by RT-PCR from peripheral blood mononuclear cells(PBMCs) and inserted into pMD18-T vector.After being confirmed by enzyme digestion and sequencing,the DNA fragment,digested with Kpn Ⅰ and Hind Ⅲ,was directionally cloned into adenovirus shuttle plasmid pAdTrack-CMV.After linearization by Pme Ⅰ digestion,the recombinant plasmid pAdTrack-CMV-TLR2 was transformed into competent AdEasier-1 germs and then homologically recombined with an adenoviral backbone plasmid pAdEasy-1 in bacteria BJ5183 to obtain the recombinant adenovirus plasmid.After confirmation,the recombinant adenovirus plasmid pAd-TLR2 was linearized with Pac Ⅰ digestion and transfected into 293 cells via liposome,and then package and adenovirus amplification were performed.The expression of green fluorescent protein(GFP) was observed,the virus titer was determined and the recombinant adenovirus was identified by PCR.ResultsThe gene fragment obtained by RT-PCR was of the same sequence as in GenBank.It was certified by restricted endonuclease digestion and PCR analysis that the recombinant adenovirus containing the TLR2 extracellular domain gene of human had been successfully constructed with a satisfactory high titer of 3?109pfu/ml.Conclusion The recombinant adenovirus containing TLR2 extracellular domain gene of human has been successfully constructed,which lays a foundation for further study on the structure and biological activity of TLR2.
