Objective To evaluate the quality of clinical trials about acupuncture and moxibustion treatment of vertebrobasilar insufficiency in China.Methods Literature of clinical trials of acupuncture was collected and analyzed,evaluated by the randomized controlled test criteria and the clinical assessing method in Cochrane handbook of international Cochrane cooperation net.Results Sixteen literatures were brought in.87.5% of the included literature had no clear description of random methods,and no allocation concealment,use of blind methods,sample size calculation,intention-to-treat analysis.Among them,62.5% had explicit diagnosis criteria,12.5% with correct randomizing method,62.5% with explicit evaluation criteria,however,31.22% with no words referring to the comparability among the groups.Conclusions Though acupuncture and moxibustion have been widely applied in prevention and treatment of vertebrobasilar insufficiency,it can not provide evidences of higher reliability for clinical treatment due to less clinical randomized controlled tests and lower quality,which severely hinder testing and verifying of clinical therapeutic effects of acupuncture and moxibustion.It is proposed that multiple central and randomized controlled test should be made,so as to search for feasible acupuncture and moxibustion methods with definite therapeutic effect for vertebrobasilar insufficiency,and provide basis for further systematical evaluation.

Background:The efficacy of traditional medicine on ulcerative colitis (UC) is often unsatisfactory, hence development of drug based on the pathogenic mechanism of UC becomes a hot topic in the research of UC.It has been revealed in recent studies that activation of nuclear factor-κB (NF-κB) is implicated as a key regulator in the immune and inflammatory responses in UC.Aims:To explore whether bortezomib, a potent proteasome inhibitor that inhibits NF-κB activation can be used for treatment of UC.Methods:Thirty-two BALB/c mice were used to induce acute experimental colitis by drinking 3%dextran sulfate sodium (DSS) freely for 7 days, and then randomly allocated into four groups injected intraperitoneally with 0.2 (low-dose group), 0.6 (medium-dose group), 1.0 mg/kg (high-dose group) bortezomib and normal saline (model control group), respectively.On the 7th day after treatment, the disease activity index (DAI) and histopathological change of colonic tissue were observed;the colitis-related parameters including peripheral blood hemoglobin (Hb), C-reactive protein (CRP) and colonic myeloperoxidase (MPO) activity were measured, and the nuclear translocation of NF-κB was assessed by electrophoretic mobility shift assay.Results:Compared with the model control group, the DAI, CRP, MPO activity, and injury score of colonic tissue were decreased gradually, and the Hb was increased gradually in mice treated with low-, medium-and high-dose bortezomib (P all <0.05).The efficacy of medium-and high-dose bortezomib was notable.In mice treated with medium-and high-dose bortezomib, nuclear translocation of NF-κB was inhibited obviously.Conclusions:Bortezomib can modulate the colonic inflammation in mice with experimental colitis by inhibiting NF-κB activation and subsequently improving the clinical manifestations, colitis-related parameters and tissue damage.Increasing the dosage of bortezomib in a safety range may enhance the treatment response.

ObjectiveTo identify the pathogens causing complicated skin and soft tissue infection and their susceptibility to antibiotics.MethodsThe clinical data on and aetiological examination findings in 99 cases of complicated skin and soft tissue infection were retrospectively analyzed.ResultsTotally,99 bacterial strains were isolated,including 51 Gram-positive bacteria(29 community-associated,22 hospital-acquired)and 48 Gram-negative bacteria ( 13 community-associated,35 hospital-acquired).Of the Gram-positive bacteria,staphylococci were the most common bacteria,which showed a high resistance rate to erythromycin (95.45％),penicillin G(72.73％),clindamycin,oxacillin and levofloxacin,but a high sensitivity to teicoplanin,vancomycin,linezolid,fusidic acid and moxifloxacin.Besides,the community-associated staphylococci possessed a higher sensitivity to trimethoprim + sulfamethoxazole,tetracycline and ciprofloxacin than the hospital-acquired staphylococci did(all P ＜ 0.05).Notably,11 of the 99 isolates were identified as methicillin-resistant staphylococcus aureus(MRSA).The four predominant Gram-negative bacteria were Pseudomonas aeruginosa,Klebsiella pneumonia,Escherichia coliand Acinetobacter baumannii.These Gram-negative bacteria,especially the hospital-acquired Gram-negative bacteria,exhibited high resistance to levofloxacin,trimethoprim + sulfamethox azole and gentamicin but favorable sensitivity to carbapenems,tobramycin,piperacillin and tazobactam.ConclusionsComplicated skin and soft tissue infection is caused by various species of bacteria with high resistance to common antibiotics.Therefore,the results of drug sensitive tests should serve as the basis for proper use of antibiotics in the treatment of complicated skin and soft tissue infection.

Objective To assess the feasibility of applying intensity-modulated radiotherapy(IMRT)simultaneous integrated boost(SIB)to replace conventional radiotherapy(CR)plus brachytherapy of whole pelvis in locally advanced cervical eaneer(LACC).Methods Five LACC patients based difference position of uterus were chosen and worked out CR and IMRT SIB plans respectively.Dose distributions were compared between IMRT SIB and CR.Results When uterus was in ante-,neutral-,retro-pnsition and deviation respectively,IMRT SIB could provide enough and homogeneous dose distribution for target volume and reduce irradiated volumes and doses for organs at risk(recta,bladder and small intestine)than CR.The doses of the A,B,and fundus of uterus were higher in IMRT SIB than CR.However,in ease of small intestine was close to or encircled the uterus,the targets volume dose would be inadequacy.Conclusions LACC IMRT SIB's dose distribution is better than CR(except excess ante-position)and may help to treat those patients who couldn't be suitable with brachytherapy.

Objective To investigate the therapeutic effects of variable-frequency electroacupuncture treatment for elderly patients with knee osteoarthritis. Methods One hundred and twenty patients with knee oste-oarthritis were randomly divided into a treatment group and a control group. The treatment group was treated with variable-frequency electroaeupuncture, while the control group was treated with muscle strength training. Before treatment and after 8 weeks of treatment, the motor function of their knee joints was evaluated according to Lysholm' s knee scoring scale, quadriceps muscle strength was evaluated according to the maximum load capacity of knee ex-tension, and postural stability was evaluated using a static balance function test. Results Lysholm scores in the treatment group improved significantly compared with those before treatment, except for the item assessing support-ing. While in the control group, compared with before treatment, there were significant differences in the items as-sessing limp, inter-locking, instability, pain and stair activity. There were significant differences in the items as-sessing inter-locking, pain, swelling, stair activity and.squatting between the two groups after treatment. The maxi-mum knee extension load improved significantly in both groups. Static balance with the eyes both open and closed also improved significantly in both groups. There were significant difference in the length, covered area, rectangle-area and length/area of the sway traces of the two groups after treatment. Conclusions Variable-frequency elec-troacupuneture can effectively improve knee function, quadriceps muscle strength and postural stability in elderly patients with knee osteoarthritis.

Objective To investigate the relationship between bacteria biofilm and bacterial culture in patients with chronic rhinosinusitis (CRS). Methods Ninety patients with CRS were enrolled in the study. Five patients with deviation of nasal septum and 10 healthy subjects served as controls. Mucosa of uncinate process or near the ostium of the maxillary sinus was obtained during endoscopic sinus surgery. All specimens were processed for bacterial culture and scanned by electron microscopy. Pearson test was performed to analyze the relationship between the presence of bacterial biofilm and the results of bacteria culture. Results The scanning electron microscopy showed bacterial biofilms in 64 (71.1%) out of 90patients with CRS, while the positive rate of bacteria culture in the study group was 66.7% (60/90). No bacterial biofilm and bacterium was detected in the control group and 26 culture-negative individuals in study group. Pearson correlation analysis showed a statistically association between bacterial biofilm and bacterial culture in CRS ( r = 0. 901, P = 0. 000). Conclusion Positive results of bacteria culture are highly correlated with the presence of bacterial biofilm in CRS patients.

Objective To investigate the expression of 5-LOX in pancreatic cancer tissue and the relationship between 5-LOX expression and expression of VEGF.Methods The expression of 5-LOXmRNA,(VEGFmRNA) in 35 pancreatic cancer fresh tissue samples were detected by semi-quantitive reverse(transcriptase)-polymerase chain reaction method.Results Expression of 5-LOXmRNA,VEGFmRNA in(pancreatic) cancer tissue were 74.3%,60% respectively,and the expression was correlated to the with(clinical) stages of the tumor;also expression of VEGFmRNA was correlated to the differentiation of the tumor.Expression of 5-LOXmRNA and VEGFmRNA were synergetic in pancreatic cancer(P

OBJECTIVE To evaluate bacterial drug resistance detection value in lower respiratory tract infection treatment.METHODS The data of distribution and antimicrobial resistance of clinical strains in sputum samples in patients with lower respiratory tract infection within some periods were collected and analyzed by WHONET software.Meanwhile,the delivery rates and detection positive rates of clinical species and antibiotics application status in clinic were retrospectively analyzed.RESULTS The delivery rates and detection positive rates of clinical species in patients with lower respiratory tract infection within some periods were 67.8% and 55.9%,respectively.The proportion of Gram-negative bacilli and Gram-positive cocci was 82.39% and 14.18%,respectively.Different drug resistance was displayed in different pathogenic bacteria.Resistant rate of Enterobacteriaceae bacteria and non-ferment bacteria against ciprofloxacin and piperacillin/tazobactam was 47.8%,34.8%and 31.5%,44.7%,respectively and resistant rate of S.aureus against levofloxacin was 63.9%.CONCLUSIONS Although the pathogenic bacteria in patients with lower respiratory tract infection show higher drug resistance to general antibiotics,most of patients with lower respiratory tract infection are treated according to clinical experience of doctors,not based on the results of bacterial culture and antimicrobial susceptibility test.Therefore,the results of bacterial culture and antimicrobial susceptibility test do not play a proper role to direct anti-infective therapy in clinic.

0.05).There was correlation between the expression of 5-LOX and TNM stages.The expression of 5-LOX in stages III~IV of pancreatic cancer was markedly higher than that in stages I~II of pancreatic cancer(P
