Objective:To survey the periodontal status of patients with metabolic syndrome in a Beijing community,so as to evaluate the relationship between periodontal status and metabolic syndrome.Methods:152 metabolic syndrome(MS)patients,106 post-acute myocardial infarction patients,211 hypertension patients and 56 healthy subjects were involved.Mesial buccal and distal lingual sites per tooth were examined.The periodontal status including plaque index(PLI),bleeding index(BI),probing depth(PD)and attachment loss(AL)as well as missing teeth number were recorded.Results:In male patients,PLI,BI and PD in MS group were higher than that in the other three groups although the mean age and smoking percentage of MS group were the lowest(P

AIM: To observe the neovascularization process with no intervention in rat allogenic penetrating keratoplasty. METHODS: Allogenic penetrating keratoplasties were successfully performed in 34 female SPF SD rats with no intervention after operations. Corneal neovascularization(CNV) process was noted on day 4, 7, 15 and 30 with operating microscope. The vascular area surface was calculated using the formula C/12×3.14×[r2-(r-I)2].RESULTS: CNV was noted in 29 out of 34 rats (85%). Firstly, the new vessels distributed around the cornea like a brush then gradually extended towards the center. The vessels were distorted and massive with branched tails, they continued growing to reticulated veins in peak time then gradually atrophied. The average neovascularization area (SE) on day 4, 7, 15 and 30 was 11.8±3.5mm2, 18.5±4.0mm2,14.4±4.3mm2 and 6.0±1.8mm2 respectively and 12.7±1.9mm2 in total. The average percentage that new vessels accounting the whole cornea area(SE) was 30.8%±8.7%, 65.3%±12.8%, 59.4%±14.5%,36.2%±10.9% and 48.7%±6.4% in total.CONCLUSION: In rat allogenic penetrating keratoplasties without intervention, CNV presented on day 4 and reached the maximum area on day 7. Then the vessels gradually atrophied, about 50% of the maximum area still remained on day 30.

Objective To study the correlation of posttraumatic growth with psychological resilience,social support and self-efficacy in breast cancer patients.Methods The questionnaires of Posttraumatic Growth Inventory (PTGI),Connor-Davidson Resilience Scale (CD-RISC),Perceived Social Support Scale (PSSS),General Self-Efficacy Scale (GSES) were used to measure 170 patients with breast cancer.Finally 159 questionnaires were returned.The investigation results were analyzed.Results Among 159 patients,the score of PTGI was (56.41±17.19) scores.The dimension score from high to low order were the relationships with others,personal strength,appreciation of life,new possibilities:(3.29±0.99),(3.19±1.00),(2.94±1.15),(2.36± 1.15) scores.The score of CD-RISC was (63.36± 14.43) scores,PSSS was (69.28±8.59) scores.The score of support from family was (24.45±3.67) scores,which was in the high level.The score of support out of family was (33.51±5.60) scores,which was in the medium level.The posttraumatic growth in breast cancer was positively correlated with the psychological resilience,perceived social support,support out of family,and general self-efficacy,P＜0.05.Conclusions The posttraumatic growth of patients with breast cancer is in the medium level,which still should be improved.The measures which can improve psychological resilience,social support,general self-efficacy of patients would also improve the posttraumatic growth in patients with breast cancer.

Objective: To systematically evaluate the clinical effects of Maxing Shigan Decoction (MXSGD), a compound traditional Chinese herbal medicine, combined with Western medicine on pneumonia in children. Methods: In this study, the relative trials published from 1994 to 2008 were searched in Chongqing Weipu Database, Chinese Journal Full-text Database, Wanfang database, Chinese Biomedical Literature Database and other electronic database by using the method of Cochrane systematic review. At the same time the information from related journals, professional data and network were hand-searched. The methodological quality of the included trials was assessed by two evaluators, and homogeneous evaluation by meta-analysis was performed. Statistical analysis of clinical data was performed by using RevMan 4.2.7 software provided by the Cochrane Collaboration. Results: A total of 146 reports were found, while only eight randomized controlled trials met the inclusion criteria. The methodology quality of the reports included in the study was evaluated by the Jadad scale, and the specific random method, allocation concealment, blinding and intention-to-treat analysis were not described in all of the eight trial reports. As MXSGD combined with Western medicine group (treatment group) was compared with Western medicine group (control group), the meta-analysis indicated that the odds ratio for the total effective rate was 4.06, and the 95% confidence interval was from 2.63 to 6.27. MXSGD combined with Western medicine was good at increasing the total effective rate as compared with Western medicine, and the difference was statistically significant (P<0.000 01). Conclusion: MXSGD combined with Western medicine can improve clinical symptoms and increase the total effective rate of the patients with pneumonia in children. However, its clinical effects should be further identified by high quality, multicenter and randomized controlled trials with large-scale design.

Objective To detect sputum quantitative bacterial culture and sputum cell counts in stable chro -nic obstructive pulmonary disease (SCOPD) patients, and explore the correlation between lower airway bacterial colo-nization(LABC) and airway inflammation.Methods 47 patients with SCOPD were chosen ,all patients induced spu-tum specimens to sputum quantitative bacterial culture and sputum cell counts ,sputum and serum IL-8 levels were al-so detected.Results There were 13 patients whose bacterial colonization of the lower respiratory tract in patients was higher than 107CFU/mL.Serum IL-8 levels of 13 patients was ( 70.65 ±19.89 ) pg/mL, sputum IL-8 levels was (364.65 ±74.19)pg/mL,all significantly higher than those whose bacterial colonization of the lower respiratory tract lower than 107CFU/mL,(15.87 ±3.01)pg/mL and (146.65 ±28.11)pg/mL,there were statistically significant difference(t=13.43,9.76,all P<0.05).After 1-year follow-up,FEV1 decline(0.071 ±0.016)L in patients whose bacterial colonization of the lower respiratory tract≥107CFU/mL,it was significantly higher than those whose bacterial colonization of the lower respiratory tract <107CFU/mL;the frequency of acute exacerbation was (2.93 ±1.07) times,significantly more than those whose bacterial colonization of the lower respiratory tract <107CFU/mL,the differ-ences were statistically significant (t=5.43,6.54,all P<0.05).Conclusion Lower respiratory tract bacterial colo-nization in patients with SCOPD can aggravate the inflammatory response and increase degree of airflow limitation .

Objective To explore the risk factors for infection following percutaneous nephrolithotomy(PCNL), and provide the basis for prevention of postoperative infection.Methods 96 patients who were performed PCNL in a hospital between August 2010 and August 2013 were chosen,clinical data of patients were retrospectively analyzed, the occurrence of postoperative infection,risk factors and isolated pathogens were analyzed.Results 35 patients (36.46%[35/96])developed infection following PCNL.Univariate analysis revealed that risk factors for postopera-tive infection were the size and shape of stone,duration of operation,and intraoperative perfusion (all P <0.05). 96 patients before operation and 18 patients after operation were performed bacterial culture for urine,a total of 39 strains were isolated,the main isolated pathogens was Escherichia coli (n=12),followed by Pseudomonas aerugi-nosa (n=8),Streptococcus viridans (n =5 ),Klebsiella pneumoniae (n =4)and Enterobacter cloacae (n =3 ). Conclusion Infection rate following PCNL is high,duration of operation and intraoperative perfusion should be re-duced,antimicrobial agents should be used rationally.

Objective To study clinical features of liver damage in primary Sj(o)gren syndrome (pSS) and its related factors.Methods One hundred and forty-nine patients of confirmed pSS hospitalized at Peking University People's Hospital were analyzed retrospectively.Results Seventeen of 149 patients of pSS (11.4%) showed liver damage,10 diagnosed as autoimmune hepatitis and seven as primary biliary liver cirrhosis.Increased serum levels of IgG,IgM and γ-globulin accounted for 88.2% and 50.8%,35.3% and 5.3%,and 94.1% and 47.7% of those complicated with and without liver damage,respectively,with statistically significant difference (P ＜ 0.05).Positive serum anti-mitochondria antibody subtype M2 (AMA-M2) was 35.3% in pSS patients with liver damage,significantly higher than that in those without liver damage (1.5%) (P ＜ 0.05).Independent risk factors significantly associated with liver damage included age (OR = 1.013,95% CI 0.971-1.058),course of illness (OR = 1.089,95% CI 1.032-1.150),serum level of γ-globulin (OR = 4.021,95% CI 1.246-12.982),positive AMA-M2 (OR = 11.82,95% CI 0.005-0.157),and positive anti-SSA (OR = 101.333,95% CI 12.653-811.560).Conclusions Liver damage occurred rather high in pSS patients and increased serum levels of IgG,IgM,γ-globulin and anti-SSA can be used to predict their complication with liver damage.Age,course of illness,serum level of γ-globulin,positive AMA-M2 and positive anti-SSA are all significantly associated with liver damage in pSS patients.

Objective To study the effect of proteasome inhibitor MG-132 on proliferation and apoptosis of human laryngeal squamous cell carcinoma Hep-2 cell line, and to explore if cisplatin (DDP) is combined with MG-132, can enhance the cytotoxicity to laryngocarcinoma cells. Methods Hep-2 cells were treated with different doses (0, 1, 2.5, 5, 10, 20 ?mol/L) of MG-132 for 48h. In another experiment, cells were treated with 2.5?mol/L MG-132 for different length of time (0, 12, 24, 48, 72h). Cells were further divided into 4 groups: control group without any treatment, MG-132 group cells were treated with 1?mol/L MG-132 alone, DDP group were treated with 10, 20, 40 and 80?mol/L DDP alone, and MG-132+DDP group were given 1?mol/L MG-132 combined with 10, 20, 40, 80?mol/L DDP for 48h. Cell growth was assessed by methyl thiazolyl tetrazolium (MTT) assay, and apoptosis was determined with flow cytometry (FCM). Results MTT assays showed that the MG-132 can effectively inhibit the proliferation of Hep-2 cell in a dose-(r=0.944, P
