OBJECTIVE:To systematically review the efficacy and safety of reinforcing kidney and invigorating spleen princi-ple in the treatment of primary osteoporosis (POP) in middle and elderly aged patients,and provide evidence-based reference for clinic. METHODS:Retrieved from VIP,Wanfang Database,CJFD,Medline,PubMed,Elsevier,Springer,Web of Science and Ovid,randomized control trials (RCT) about reinforcing kidney and invigorating spleen principle (test group) versus other meth-ods(no reinforcing kidney and invigorating spleen principle,control group)in the treatment of POP were collected. Meta-analysis was performed by using Rev Man 5.3 software provided by Cochrane after data extraction and quality evaluation modified by Jadad scale. RESULTS:Totally 28 RCTs were enrolled,involving 2849 patients. Results of Meta-analysis showed,the total effective rate [OR=3.80,95%CI(2.76,5.23),P<0.001],BGP level [MD=2.23,95%CI(1.80,2.66),P<0.001],BMD level of femoral neck [MD=0.04,95%CI(0.00,0.08),P=0.05] and BMD level of lumbar spine [MD=0.07,95%CI(0.03,0.11),P=0.001] in test group were significantly higher than control group,ALP level [MD=-5.59,95%CI(-10.51,-0.66),P=0.03] and VAS score [MD=-1.38,95%CI(-1.87,-0.89),P<0.001] were significantly lower than control group,with statistical significance. There were no significant differences in U-Ca/Cr [MD=-0.07,95%CI(-0.17,0.02),P=0.12] and serum Ca2+ level [MD=0.16,95%CI (-0.07,0.39),P=0.17] in 2 groups. CONCLUSIONS:Reinforcing kidney and invigorating spleen principle can improve patients' osteogenesis during bone metabolism,reduce the activity of the osteoclastic process and relief patients'pain in the treatment of POP.

A high efficiency phenol-degrading bacterial strain PS1 was isolated from the drainage ditch of chemical laboratory of East China Institute of Technology.PS1 is a coccus,Gram negative and can live on phenol as its sole carbon and energy source.PS1 to identified as a strain of Raoultella sp.by 16S rRNA gene sequence analysis,which can degrade and tolerate more than 3500mg/L phenol.When phenol concentration is 500mg/L and 1000mg/L,PS1 can completely degrade it in 22 h and 32h,respectively.And while it is between 1500mg/L～3000mg/L,all phenol can be degraded by PS1 in 32h～50h.When phenol concentration is 2500mg/L,the phenol-degrading rate is the biggest and can reach to 78.1mg/h.The optimum growth and phenol-degrading conditions were obtained by orthogonal experiment,which are 25℃,pH6.5,glucose concentration 500mg/L and 20℃,pH7.0,glucose concentration 500mg/L,respectively.

Objective To investigate the diagnosis and treatment of intraductal papillary mucinous neoplasm (IPMN) of the pancreas.Methods The clinical data of patients with pathologically verified IPMN who underwent surgical treatment between January 2006 to April 2014 in the First Affiliated Hospital of Harbin Medical University were studied retrospectively.There were 27 males and 21 females.The average age was (57.8 ± 8.8) years old.The average caliber of the main pancreatic duct was (1.1 ± 0.6) cm.The average size of the branch duct IPMN was (4.6 ± 1.5) cm.Results 35 patients underwent pancreaticoduodenectomy.Eight patients underwent distal pancreatectomy.Two patients underwent duodenum-preserving pancreatic head resection.Two patients underwent splenic-preserving distal pancreatectomy and one patient underwent total pancreatectomy.No patient died in perioperative period,and the median length of hospital stay after surgery was 14.3 days.Postoperative pathological examination revealed 5 (10.4％) adenoma,12 (25.0％) moderate-grade dysplasia,14 (29.2％) high-grade dysplasia and 17 (35.4％) invasive carcinoma.The postoperative complication rate was 22.9％.The mean follow up period for the noninvasive tumors was 48.9 months,with no recurrence or deaths.The mean follow up period of the invasive tumors was 43.2 months,with 1 death and no recurrence.Conclusions The indications for resection of IPMN should be based on treatment guidelines and on the patient' s general condition.It is suggested that the diagnosis and treatment of IPMN should be conducted in specialized pancreatic surgery centers.

This study is to investigate the effect of Vam3, a dimeric derivative of resveratrol, on SNP-induced apoptosis and its potential mechanism in rat articular chondrocytes. Isolated rat articular chondrocytes were treated with sodium nitroprusside (SNP), a NO donor, to induce apoptosis. Apoptosis percentage was evaluated by Annexin V-PI and nucleus fracture was examined by DAPI staining. Level of intracellular reactive oxygen species (ROS) was detected using 2, 7'-dichlorofluorescin diacetate (DCFH-DA) as a fluorescence probe by fluorescence microplate reader. The change in mitochondrial membrane potential was detected by TMRE staining. Expressions of SIRT1, acetylated p53 (ac-p53), cleaved caspase 9 and cleaved caspase 3 were determined by Western blotting. It showed that Vam3 up to 10 micromol x L(-1) could significantly reduce SNP-induced rat articular chondrocytes apoptosis (P < 0.01) and nucleus fracture, inhibit the increase of intracellular ROS level (P < 0.01) and reverse the decrease in mitochondrial membrane potential (P < 0.01). Simultaneously, Vam3 could upregulate the expression of SIRT1, deacetylate p53, and inhibit the cleavage of caspase 9 and caspase 3 (P < 0.01) of rat articular chondrocytes exposed to SNP. This study indicates Vam3 could protect rat articular chondrocytes against SNP-induced apoptosis, perhaps through the upregulation of SIRT1 and deacetylation of p53.

AIM:To investigate the dependence of the adrenoceptor regulation on oxidative stress in the rats with cardiac injury induced by high sympathetic activity .METHODS: Healthy SD rats were randomly divided into 7 groups:control, model, propranolol (Pro), prazosin (Praz), Pro+Praz, vitamin E (VE) and Pro+Praz+VE.The rats were intraperitoneally injected with norepinephrine ( NE) for continuous 16 d to reproduce cardiac injury , and treated with the respective drugs .During the experimental process , the body weight was recorded .At the end of the experiments , the following parameters were measured:the ventricular remodeling indexes ( cardiac index and hydroxyproline of the left ven-tricle), histopathologic examination , oxidative/antioxidative indexes [MDA, SOD, catalase (CAT), GSH-Px and total an-tioxidant capacity (T-AOC)], and energy metabolism (Na+-K+ATPase and Ca2+-Mg2+ATPase).RESULTS: The in-crease of body weight in model group was significantly slower than that in control group after 9 d of treatment (P<0.05). The cardiac index and left ventricular hypertrophy were significantly increased .Oxidation/antioxidation and energy metabo-lism were disturbed.In Pro, Praz, Pro+Praz and VE groups, the body weight, cardiac index, left ventricular fibrosis and oxidative/antioxidative dysfunction were ameliorated .Pro, Praz and Pro +Praz increased the activity of Na +-K+ATPase and Ca2+-Mg2+ATPase.Treatment with Pro+Praz showed the best result in all of the indexes (P<0.05).CONCLU-SION:The dependence of adrenoceptor regulation plays an important role in the formation of oxidative stress in the process of rat cardiac injury induced by high sympathetic activity .

Porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) are very two important pathogens that have coursed huge economic losses in swine production in worldwide. In this study,a vector pCMV-TJM containing the full-length cDNA clone of PRRSV attenuated strain TJM-F92 was firstly constructed by PCR method. Then a gene sequence containing Afl II/Mlu I e restriction enzyme sites and a transcription regulatory sequence for ORF6 (TRS6) was inserted be- tween ORF7 and 3'UTR, yielding a expression vector pCMV-TJM-TRS. Subsequently, a plasmid pCMV-TJM-Cap was constructed by cloning of PCV2 ORF2 gene into the unique sites Afl II /Mlu I of pCMV- TJM-TRS plasmid DNA. Then three recombinant PRRSV, rTJM, rTJM/TRS and rTJM/Cap, were rescued by transfection of pCMV-TJM, pCMV-TJM-TRS and pCMV-TJM-Cap into Marc-145 cells, respectively,and confirmed by the genome sequence, restriction enzyme digestion, Western Blot and IFA. They all had the molecular markers which was different from the parent virus. The growth characteristics of the rescued viruses were similar to that of parent virus. rTJM/Cap could also express efficiently PCV2 Cap protein in Marc-145 cells. At passage 8, it still had PCV2 ORF2 gene which examined by RT-PCR. It indicated that the full-length cDNA clone of PRRSV attenuated strain TJM-F92 and recombinant PRRSV rTJM/Cap expressing PCV2 Cap protein were successfully constructed. It made an important foundation for studying on the pathogenic mechanisms of PRRSV and PRRSV-PCV2 vaccine in the future.
