Objective:To explore the lipid-regulating effect and safety of atorvastatin combined fenofibrate therapy in patients with coronary heart disease (CHD)complicated diabetes mellitus (DM).Methods:A total of 100 pa-tients with CHD complicated DM were enrolled.Based on routine treatment,patients were randomly and equally di-vided into statin group (n=50,received 20mg atorvastatin,once/night)and combined treatment group (n=50,re-ceived 20mg atrovastatin once/night,combined fenofibrate 200mg once/d).Serum levels of total cholesterol (TC), triglyceride (TG),low density lipoprotein cholesterol (LDL-C)and high density lipoprotein cholesterol (HDL-C) were measured before,six and 12 weeks after treatment,levels and standard-reaching rates of above blood lipid were observed before and after treatment;adverse reactions and clinical events were recorded.Results:Compared with before treatment after six-week treatment,there were significant reductions in serum levels of TC,TG and LDL-C in both groups,and they further decreased after 12-week treatment (P <0.05~ <0.01),compared with statin group after 12-week treatment,there were significant reductions in levels of TC [(4.35±0.71)mmol/L vs. (4.09±0.56)mmol/L],TG [(2.35±0.62)mmol/L vs.(1.65±0.49)mmol/L]and LDL-C [(2.01 ±0.39) mmol/L vs.(1.85±0.22)mmol/L]in combined treatment group,P <0.05 or <0.01;HDL-C level significantly rose in both groups after treatment,and it′s more significant after 12 weeks,but there was no significant difference between statin group and combined treatment group (P >0.05).After 12-week treatment,standard-reaching rates of LDL-C,TG,HDL-C,all standard-reaching of above three indexes and non HDL-C (70%,68%,80%,58% and 70%)in combined treatment group were significantly higher than those of statin group (50%,46%,48%,10% and 48%)respectively,P <0.05 or <0.01. No severe adverse reactions were observed in two groups during treatment. Conclusion:Atorvastatin combined fenofibrate treatment is more effective than atorvastatin monotherapy in patients with coronary heart disease complicated diabetes mellitus.It can improve blood lipid level more comprehensively, contribute to comprehensive standard-reaching of blood lipids,and possess better safety and tolerance.

Objective To investigate the distribution features and antibiotic drug resistance of infection pathogens isolated from elderly patients with malignancies complicated with infection following treatment in an open hematology ward.Methods From January 2010 to June 2012,specimens from hospitalized elderly patients with concurrent infection were cultured to isolate infection pathogens through routine methods.Antimicrobial susceptibility tests were performed by the microdilution method.Results A total of 302 strains of infection pathogens were isolated from all detected samples,among which isolated strains of Gram-positive bacteria,Gram-negative bacteria and fungi were 91,194 and 17 strains,respectively.Isolated fungi were mostly susceptible to antifungal drugs.Gram-negative bacteria were highly susceptible to carbapenem,while Gram-positive bacteria were most sensitive to vancomycin and teicoplanin.Conclnsion The nosocomial infection pathogens of elderly patients with malignancies in hematology ward are most likely Gram-negative bacteria.Before specimens culture results and susceptibility are known,all these patients should be empirically treated with broad spectrum antibiotics,which have the most activity against Gram-negative bacteria as well as Gram-positive bacteria coverage.

With homology cloning approaches coupling with RACE (rapid-amplification of cDNA ends) techniques, the full-length coding sequence of pathogenesis-related protein PR10-1 with differential expression was cloned from the total RNA of the root of Panax notoginseng, and its function was explored furtherly. As a result, the longest 465 bp ORF (named as PnPR10-1 with the Accession No. KJ741402 in GenBank) was detected from the cloned sequence with full-length of cDNA of 863 bp. The corresponding peptide encoded consisted of 155 amino acids, contained some domains such as Bet-v-I, and showed high similarity with that from Panax ginseng by analysis of phylogenetic trees created from the alignments. Real-time quantitative PCR showed that the expression of PnPR10-1 gene was constitutive in different tissues of 1-3 year old plant, suggesting that it might be involved in growth, development, and secondary metabolism; yet it was up-regulated significantly with the infection of Fusarium oxysporum in root, suggesting that it might be involved in defense against many diseases including root rot in P. notoginseng.

Objective To discuss the safety and short-term efficacy of MR-guided focused ultrasound surgery (MRgFUS) for pain palliation of bone metastases patients.Methods Fourteen patients with painful bone metastases were recruited in this prospective study.The treating efficacy was characterized by numerical rating scale (NRS),the brief pain inventory quality of life (BPI-QOL) survey,and Karnosky performance status scale (KPS).Adverse events occurred pre-and post-treatment were analyzed.Normal distributed statistics was analyzed by using paired-samples t test or Wilcoxon rank sum test.Results Fourteen patients were treated with MRgFUS,2 patients dropped out of the study.The NRS ratings are 6.50(4.00),5.00 (5.25),2.50(5.00),2.50(4.75),2.00 (6.00) for pre-treatment,one week,one month,two months,and three months,respectively.Such variances of NRS ratings were statistically significant (Z=-2.773,-2.740,-2.769,-2.675;P＜0.05).The BPI-QOL ratings were (42.42± 8.27),(30.67 ± 12.29),(29.17±15.38),(29.92± 17.67) and (35.67± 19.28),respectively.The BPI-QOL ratings decreased in the first two months after the treatment which is statistically significant (t=3.231,2.820 and 2.453;P＜0.05);whereas for the third month,the BPI-QOL rating was statistically insignificant compared with the one before the treatment (P＞0.05).The KPS ratings were 80(28),80(20),65(45) for pre-treatment,one week and three months after treatment,respectively.Three months after the treatment,the KPS ratings decreased which was statistically significant compared with the one before the treatment (Z=-2.204,P＜0.05).After the treatment,one patient developed deep venous thrombosis,three patients reported lower extremities numbness,two patients had soft tissue edema around the lesions.Conclusions MRgFUS is effective for short-term pain palliation of bone metastases.Such noninvasive technique is safe and can improve patients' living condition.

OBJECTIVE: To analyze and compare different methods for assessment of the limbs joints function and to discuss the rationality of the methods. METHODS: Eight hundred and six cases were collected from the Fujian Minzhong Forensic Appraisal Center from 2007 to 2010. These cases included injuries of large limbs joints with or without peripheral nerve injury. The loss of joint function was calculated according to the simple joint mobility method or the table method introduced in the book "Forensic Clinical Judicial Authentication Practice". The results of disability evaluation with different methods were analyzed and compared between different joints and injury patterns. RESULTS: In 642 cases of simple joint injuries without peripheral nerve injury, the results of disability evaluation based on simple joint mobility were the same as that based on the table. In 118 cases of joint injuries with peripheral nerve injury, all of them could be classified as disability, 33 cases (28.00%) had higher degree based on the table method than based on the simple joint mobility method. While 21 cases (17.80%) did not be evaluated as disabled based on the simple joint mobility method. CONCLUSION The evaluation for loss of limb function would be easier, more scientific and reasonable by the direct table method than the simple joint mobility method.

Aim To observe the effects of metformin (MET) on the silencing regulatory protein 1 (SIRT1) mRNA and protein expression in renal tissues of type 2 diabetic mellitus (T2DM) rats, and explore its reno-protective mechanisms. Methods Thirty model T2DM rats were randomly divided to glibenclamide in-tervention group (GLY group, 5 mg·kg-1·d-1), metformin intervention group (MET group,300 mg· kg-1· d-1) and diabetic control group (T2DM group),and 10 rats with normal glucose tolerance were used as normal control(NC group). After 8 weeks, HbA1c,blood glucose (BG), urea nitrogen (BUN), urinary albumin, creatinine and glomerular basement membrane thickness (GBMT) were detected. The ex-pression of SIRT1 protein in renal tissues was detected by immunohistochemistry, the expression of SIRT1 mRNA in renal tissues was detected by real-time PCR, and urinary SIRT1 protein was detected by ELISA. Results At the end of 8 weeks, the levels of BG,HbA1c,urinary albumin/urinary creatinine(UACR), urinary SIRT1/urinary creatinine (USIR) and GBMT in MET and GLY groups were significantly lower than those in T2DM group (P<0.05). There was no sig-nificant difference in BG, HbA1c and GBMT between MET group and GLY group (P>0.05). The expres-sions of SIRT1 mRNA and protein in MET group were significantly lower than those in NC group (P <0.05), but higher than those in T2DM group (P <0.05). The UACR, expression of SIRT1of renal tis-sues in MET group was higher than that in GLY group (P<0.05),but urinary SIRT1 protein was lower than that in GLY group (P <0.05). Conclusion Met-formin can increase the expressions of SIRT1 in renal tissues of T2DM rats,which may be related to its renal protection.

Objective To investigate Bartonella infection in rodent hosts from different environments and types of climate in Fujian coastal regions. Genetypes of the Bartonella strains was also studied to provide scientific basis for prevention and control of the correlated diseases. Methods By random sampling method, we selected six study sites in Fujian southeastern coastal regions. Rodents were captured by cages to Isolate Bartonella strains. Bartonella-like isolates were confirmed by polymerase chain reaction (PCR). The 379 bp fragment of gltA gene was sequenced and the growth and development tree was constructed to determine Bartonella species. Distribution of Bartonella species in the different area and related hosts was also analysed. Results Bartonella species were isolated from 188 of 1161 small animals including five rodent species. The infected animals were grouped into 2 genera and 2 orders. They were Suncus murinus, Rattas norvegicus, Rnttus flavipectus, Mus masculus and Rattus rattus. The overall prevalence of Bartonella bacteremia was 16.19% in the most prevalent species of rodents in Fujian southeastern coastal regions including 21.43% in Suncus murinus, 13.54% in Rattas norvegicus and 18.27% in Rattus flavipectus. Rodents in every investigated areas were infected by Bartonella species (9.25% in Ningde, 9.52% in Fuzhou, 9.38% in Putian, 28.18% in Quanzhou, 17.42% in Xiamen and 13.33% in Zhangzhou). There were significant differences among infected rates in different annual accumulated temperature districts (χ~2=12.93, P<0.001). Isolates from rodents were clustered in three genotypes (B.elizabethae, B.qeenslandensis and B.tribocorum A, B). Conclusion The local rodents in Fujian southeastern coastal regions were widely infected by Bartonella spp. Differences among the prevalent species of Bartonella in Fujian southeastern coastal region, Yunan and Beijing were noticed. Our findings suggested there was a need to study the prevalence, related vectors and the molecular organism of Bartonella spp.
