Objective To study the role of protective antigen(PA)and N-terminal segment of lethal factor (LFn)in the entrance of EGFP(enhanced green fluorescent protein)into HeLa cells. Methods The DNA fragments encoding LFn and EGFP were amplified,respectively,and cloned into the plasmid pET-21 a(+)one after another to construct a recombinant plasmid pET-LFn-EGFP. The plasmid was txansformed into BL21 cells to express LFn-EGFP protein under the induction of IPTG. The protein was purified by Ni chelating chromatography. After incubation with LFn-EGFP in the presence of PA or not, the HeLa cells were analyzed by flow cytometry or laser confocal microscopy. Results The fusion protein LFn-EGFP was purified by over 90% homogeneity and retained the ability of LF to bind with PA when incubated with J774A.1 macrophage cells,and could get into HeLa cells. Conclusion The LFn-EGFP could enter the HeLa cells in a PA independent pathway. But PA could help more LFn-EGFP molecules enter into HeLa cells.

The data mining technique is adopted to analyze characteristics and rules of acupoint and meridian selection of acupuncture-moxibustion for treatment of vertigo at different time periods in the ancient. The data is collected from literature regarding acupuncture-moxibustion from the pre-Qin period to the end of Qing Dynasty, so as to establish a clinical literature database of ancient acupuncture-moxibustion for treatment of vertigo. Data mining method is applied to analyze the commonly used meridians, acupoints and special acupoints in different dynasties, also possible rules are explored. Totally 82 pieces of prescription of acupuncture-moxibustion for treatment of vertigo are included. In the history the leading selection of acupoitns are Fengchi (GB 20), Hegu (LI 4), Shangxing (GV 23) and Jiexi (ST 41) while that of meridians are mainly three yang meridians of foot and the Governor Vessel, especially the acupoints on the Bladder Meridian of foot yangming had the highest utilization rate, accounting for 23.04%. The acupoint selection is characterized by special acupoint, accounting for 80.6%, among which the crossing points are the most common choice. Distal-proximal acupoints combination is the most frequent method. The results indicate that the ancient acupuncture-moxibustion for treatment of vertigo focused on acupoints in the yang meridians, and the specific acupoints play an essential role in prescription; also the principle of syndrome differentiation and selecting acupoints along the meridians could be seen.

OBJECTIVEThe aim of this study was to evaluate the efficacy and safety of combination therapy with simvastatin and fenofibrate in patients with combined hyperlipidemia.
METHODSA total of 221 patients with combined hyperlipidemia were randomly assigned to receive 10 mg simvastatin (n = 72) or 200 mg fenofibrate (n = 68), or a combination of 10 mg simvastatin + 200 mg fenofibrate (n = 81) for 6 months. Lipid profiles, physical and laboratory investigations for adverse effects were assessed.
RESULTS(1) Combination treatment were more effective in normalizing lipid profile than any monotherapy. Serum TC, LDL-C, and TG were reduced by 30%, 37% and 56% respectively, whilst HDL-C significantly increased by 24% (all P < 0.01). The improvement in TG and HDL-C achieved by combination treatment was superior to fenofibrate or simvastatin alone. (2) The success rate of TC, LDL-C and TG control in the combination therapy group were 51%, 55% and 61% respectively, with an overall success rate (all three together) of 45%, which was superior to either drug given as monotherapy. (3) All treatments were well tolerated with no increase in adverse events for combination therapy versus monotherapy.
CONCLUSIONThe results of this study demonstrated that combination therapy with fenofibrate (200 mg/day) and low-dose simvastatin (10 mg/day) is more effective than monotherapy in patients with combined hyperlipidemia, and is generally safe and well tolerated.

BACKGROUND:Elderly patients with degenerative lumbar degeneration often appear insufficient holding power of pedicle screw in spine surgery, which is prone to occur de-pinning and leads to insecure fixation. How to increase the holding power of screws has become a hot research. OBJECTIVE:To observe the early clinical effect of pedicle screws with cement augmentation for treating lumbar degenerative diseases in elderly patients. METHODS:A total of 65 old patients with lumbar degenerative diseases received a treatment between August 2012 and April 2014, and were divided into two groups according to the treatment strategy:treatment group (n=24;internal fixation of pedicle screws with cement augmentation) and control group (n=41;routine internal fixation of pedicle screws). General conditions of patients in two groups were observed and compared. Visual analog scale (VAS) and Japanese Orthopaedic Association (JOA) score system were used for evaluating the lumbar and back pain, and restoration of neurological function in lower limbs respectively. RESULTS AND CONCLUSION:Al of the patients successful y received the surgery and then were fol owed up from 3 to 20 months. The anterioposterior and lateral X-ray film revealed no loosening, loss, fracture of the screws, and no loss of intervetebral space height was found. There was no significant difference in the blood loss and hospital stay between two groups (P>0.05). JOA at postoperative 3 and 6 months, and VAS score at postoperative 3 months were significantly improved after the treatment of pedicle screws with cement augmentation, when compared to control group (P<0.05). VAS scores showed no difference at 6 months postoperatively in two groups (P>0.05). Pedicle screws with cement augmentation for treating lumbar degenerative diseases have the advantages of improving the screws holding strength, reconstructing the stability of lumbar vertebra and obtaining clinical efficacy on degenerative spine.
