Objective To explore the relationship between Sirt1 single nucleotide polymorphisms ( rs2236319 ) and chronic obstructive pulmonary disease ( COPD ) susceptibility. Methods The subjects included 149 patients with stable COPD in the First People′s Hospital of Jining outpatient or ward from March 2014 to March 2015, and 160 cases of the same period health check. Sirt1?rs 2236319 genotype distribution frequency was detected by real?time PCR,and the levels of inflammatory factors were compared,including IL?6 and CRP. Results The AA,AG,GG genotype frequency of COPD group were 59. 1%( 88/149) ,35. 6%( 53/149),5. 4%(8/149) respectively,of control group were 45. 0%(72/160),48. 8%(78/160),6. 3%(10/160) respectively,the allele A,G frequency of COPD group were 76. 8%(229/298),23. 2%(69/298) respectively,of control group were 69. 4%( 222/320 ) , 30. 6%( 98/320 ) respectively, there were statistically significant differences between the two groups(χ2=6. 23,6. 06,P<0. 05) . IL?6 and CRP levels were significantly increased in COPD group carrying AA genotype as compared to COPD group carrying AG+GG genotype((10. 30±0. 40) mmol/L,(10. 16±0. 36) mmol/L;(2. 56±0. 20) mg/L,(2. 46±0. 22) mg/L;F=4. 52,8. 04,P<0. 05);There were no significant differences in terms of IL?6 and CRP levels in control group carrying AA genotype as compared to control group carrying AG+GG genotype ( P>0. 05 ) . Both the level of IL?6 and CRP were significantly increased in COPD group carrying AA genotype and AG+GG carriers compared to controls((10. 30 ± 0. 40 ) , ( 9. 88 ± 0. 56 ) mmol/L, ( 10. 16 ± 0. 36 ) , ( 9. 86 ± 0. 57 ) mmol/L;( 2. 56 ± 0. 20 ) , ( 2. 28±0. 25) mg/L,(2. 46±0. 22),(2. 26±0. 26) mg/L;F=34. 52,11. 09,73. 06,19. 38;P<0. 01). Conclusion The polymorphisms of Sirt1?rs2236319 may be an additional risk factor for COPD and associate with inflammatory factors. Furthermore the involvement of rs2236319 in the initiation and progression of COPD may relate to inflammatory processes.

Patients treated with radiotherapy (RT) might experience a large variation in normal tissues. Severe radiation damage in a minority of patients limits the doses that might be safe given to the majority. The possibility of predicting such radiation-induced damage would provide a better treatment schedule for the patients. Several predictive tests in peripheral blood lymphocytes such as initial DNA damage, radiation-induced apoptosis and genetic variation have been proposed to know the individual sensitivity of patients to the radiotherapy schedules. This study aimed to summarize the main studies regarding to this ifeld.

Objective To investigate the incidence of the pusher syndrome in stroke patients, and the relationship between the syndrome and the neuropsychological symptoms and location of brain lesion, and to investigate the mechanism and the physiotherapy intervention of pusher syndrome. Methods Thirty nine patients(25 male, 14 female, 62.5?9.4 years old) with pusher syndrome were examined, 91 patients(57 male,34 female, 58.4?11.6 years old) without ipsilateral pushing served as control. The lesion areas, neuropsychological syndrome and the Barthel Index(BI) were recorded, and the physiotherapy were administered in the patients. Results The incidence of pusher syndrome was 30% in the patients studied, corresponding to 17% of the total number of stroke patients in the study period. The percentage of pusher syndrome occurrence was higher in the patients with right side lesion than those with left side lesion ( P

AIM: To investigate the clinical features of acquired immune deficiency syndrome ( AIDS) patients associated ocular diseases in Urumqi and the relationship between ocular fundus manifestations and CD4+T cell count.
METHODS: The fundus of 93 AIDS patients were examined by indirect ophthalmoscopy. The clinical symptoms and CD4+T cell count of those patients with fundus changes were analyzed.
RESULTS: Thirteen patients were found having fundus changes which occurred in one eye of 4 patients and two eyes of 9 patients, respectively, and the total detection rate was 14. 0%. Seven patients had vision changes, and the main clinical features of retinal lesion were cotton wool spot and hemorrhage of retina. Four patients were diagnosed as retinitis with cytomegalovirus ( CMV ) infection and 9 patients were diagnosed as HIV related retinopathy diseases. Seven patients among 37 patients with CD4+T cell count ≤100cell/μL had fundus changes related AIDS, and the detection rate was 18. 9%; while 6 patients among 56 patients with CD4+T cell count >100cell/μL had fundus changes related AIDS, and the detection rate was 10. 7%. There was statistical difference between the two detection rates (P<0. 05).
CONCLUSION: No specificity was found of those patients with the clinical manifestation of HIV- related retinopathy, and those patients are easy to be missed diagnosis. A number of AIDS patients have fundus changes without any vision changes. Therefore, it is very useful for AIDS patients to be carried out the routine fundus examination for the early diagnosis and treatment.

Objective To assess the efficacy of radiofrequency therapy combined with ozone injection in the treatment of lumbar disc protrusion. Methods A total of 202 patients with lumbar disk protrusion were included and divided into three groups:radiofrequency (RF) group, ozone (Oz) group, and combination (Co) group. The efficacy was evaluated by visual analogue scale (VAS), Macnab curative effect evaluation, and oswestry disability index (ODI) at 1d, 1m and 6m after treat?ment. Results There were no significant differences in gender, age, the course of disease, preoperative VAS scores and ODI scores (P>0.05). All patients were operated successfully. There were no infection of the intervertebral disc, no compli?cations of spinal cord, nerve and no blood vessel injury. There were no significant differences in preoperative VAS and ODI scores between three groups. The VAS and ODI scores were significantly lower at 6 month and 12 month after operation in Co group combined with those of RF group and Oz group. There were no significant differences in these two scores between RF group and Oz group (P>0.05). There were no significant differences in effective rates at 1d, 6 month and 12 month after operation between three groups (P>0.05). But the excellent and good effective rates were higher in Co group than those of RF and Oz groups. There were no significant differences in excellent and good effective rates between RF group and Oz group. Conclusion The therapy of radiofrequency combined with ozone injection is an efficient and mini-invasive tech?nique for the treatment of lumbar disc protrusion and worth promoting.

Objective:To investigate the effects of nitric oxide(NO) and inducible nitric oxide synthase (iNOS) in the experimental abdominal aortic aneurysm (AAA) rat model.Methods:An intra-aortic elastase infusion model was used.Control rats received intra-aortic saline infusion.In the remaining groups,intra-aortic elastase infusion was used to induce aneurysm formation.These rats were treated with intraperitoneal injections of saline postoperatively(experimental group),aminoguanidine postoperatively(medicine group).Serum NO and aortic diameter were measured,Changes of histology,iNOS and MMP-9 were observed in the aortic wall.Results:Experimental group produced AAAs with significant production of iNOS,MMPs and serum NO compared with controls.In medicine group reduced aneurysm size and displayed suppression of MMPs expression,inflammatory infiltrates and serum NO production were detected.Conclusion:Expression of iNOS and MMP-9 are induced and serum NO levels are increased in experimental AAA,iNOS and NO production by iNOS play an important role with detrimental effects during experimental aneurysm development.

AIM: To investigate the activation dynamics and the intracellular localization of p38 protein kinase in Raw264.7 cells after lipopolysaccharide (LPS) stimulation.METHODS: Protein kinase assay and immunogold electron microscope technique were used to check the activation dynamics and distribution of p38 MAPK in Raw264.7 cells before and after LPS stimulation. RESULTS: The kinase assay results showed that a marked increase in p38 activity was detected 15 min after LPS treatment, and reached maximal activity 30 min post stimulation, then dropped down and got closed to the pre-stimulated level 2 h later. The optimal LPS concentration for treatment was 100 ?g/L. The immunogold electron microscope data showed that p38 spread evenly in every part of the cytosol of the non-stimulated and EGF stimulated Raw264.7 cells, such as endoplasmic reticulum, mitochondria, lysosome, while the golden granules intensity in the cytosol area decreased and in the nuclear area increased significantly after LPS stimulation.CONCLUSION: p38 MAPK moves to the nuclei of Raw264.7 cells on account of stimulation by LPS.

Objective To observe the expression of SGK in decidua in patients with unexplained recurrent spontaneous abortion(URSA) and to investigate its role in the course of apoptosis.Methods The expression of SGK was detected by immunohistochemistry in decidua of URSA(abortion group,n =50) and normal first trimester pregnant women(control group,n =30).The apoptotic index was detected by TUNEL.Results Compared with the control group,the positive expression of SGK decreased significantly in the abortion group,and the difference was statistically significant(x2 =6.78,P ＜ 0.05).The average apoptotic index of the abortion group was (8.19 ± 3.58) ％,which was significantly higher than (2.87 ±1.07)％ of the control group(t =7.94,P＜0.05).Conclusion Intensive apoptosis,the decreasing positive expression rate of SGK in decidua cells may play critical roles in URSA.

Objective To investigate the advantages and disadvantages of two different approaches (i.e.internal jugular vein and subclavian vein) when used for the implantation of central venus access ports (CVAP).Methods We retrospectively analyzed 620 patients who underwent the implantation of CVAP via the approach of internal jugular vein (n =222) or subclavian vein (n =398) and compared the success rate on first attempt as well as the incidences of peroperative and long-term complications.Results The implantation of CVAP was successfully performed in all the 620 patients,with the success rate on first attempt being 97.24％ (387/398) in the subclavian vein group and 89.19％ (198/222) in the internal jugular vein group (U =0.171,P ＜ 0.01).The incidences of perioperative/long-term complications were 0.90％ (2/222) /1.80％ (4/222) in the internal jugular vein group and 1.26％ (5/398) /2.01％ (8/398) in the subclavian vein group,showing no significant differences (all P ＞ 0.05).Conclusions The implantation of CVAP via either the internal jugular vein approach or subclavian vein approach is safe and reliable.Few complications will occur if performed properly.
