Objective　To explore the changes of ER-IR and the ultra structure in the medial preoptic area, arcuate nuclei of early-aged mice treated with estrogen. Methods　Immunohistochemistry assay and electron microscopy were used in this study. Results　ER-IR in the medical preoptic area and arcuate nuclei were greatly reduced after estrogen was given. The cell nuclei of neurons in these areas migrated towards the side, the nuclear membrane became folded, synapse became richer, and the number of synapse vesicle increased. Conclusion　Estrogen can affect the neuron structure and function through the change of estrogen receptor expression in the medial preoptic area and arcuate nuclei of the hypothalamus cardiovascular center.

Objective To investigate suitable condition for extraction of the active components from Ajuga nipponensis (A. nipponensis). Methods Orthogonal experimental design was used to determine the optimal extraction parameters for ecdysterones and flavonoids. Finally, the hepatoprotective abilities of A. nipponensis extracts were evaluated by CCl

OBJECTIVETo study the chemical constituents in roots of Caragana sinica.

METHODThe constituents were isolated by silica gel column chromatography, and their structures were identified by spectroscopic methods.

RESULTSeven compounds were identified as (+) - stenophyllol B (1), 4-hydroxybenzoic acid (2), odoratin (3), resveratrol (4), cararosinol A (5), leachinol C (6), carasinaurone (7) respectively.

CONCLUSIONCompound 1 was a new compound which was the enantiomer of stenophyllol B. Compounds 2-6 were obtained from the plant for the first time.

OBJECTIVETo study clinical effects of the over-articular external fixator combined with limited internal fixation for the treatment of Pilon fractures caused by high energy.

METHODSFrom September 2003 to April 2011, 36 patients with Pilon fractures caused by high energy were treated with the over-articular external fixator combined with limited internal fixator. There were 25 males and 11 females, ranging in age from 16 to 72 years old,with an average of 38 years old. The diagnoses of all patients were determined by conventional X-ray examination or three-dimensional spiral CT examination. The AOFAS scoring criteria was used to evaluate the therapeutic effects. The patients with comminuted fractures were treated with screw or Kirschner wire fixation without uncovering periost so as to enhance stability between fracture end and bone blocks,followed by the fixation with over-articular external fixators.

RESULTSAll the patients were followed up, and the duration ranged from 4 to 27 months, with an average of 13 months. Thirty-two patients got wound healing at the first stage. And the bone union duration ranged from 2 to 6 months, with a mean of 3 months. According to the AOFAS ankle-hindfoot subjective scoring standard, 13 patients got an excellent result, 20 good and 3 fair, with an score of 88.2 +/- 3.6. Twelve patients had infections at pinhole, 5 patients had pinhole pain. One patient had the fixator broken induced by over loading, who was cured after treatment. There were no complications such as nerve or vascular injuries, or osteomyelitis.

CONCLUSIONThe over-articular external fixation combined with limited internal fixation for the treatment of Pilon fractures caused by high energy is an ideal method, which has such advantages as reliable fixation, simple operation, coincidence with principles of biomechanical fixation, and benefit for fracture healing.

OBJECTIVETo understand preliminary relation between patient's confident degree in acupuncture and moxibustion with the therapeutic effect on pain.

METHODSFifteen cases with pain were investigated. The confident degree for acupuncture and moxibustion and pain degree were evaluated by the patient with visual analogue scale (VAS), and the pain VAS scores before and after acupuncture were recorded as the indexes for assessment of the therapeutic effect.

RESULTSAfter acupuncture treatment, the average pain VAS score was decreased by 3.3 +/- 2.8 (P< 0 . 5). There was no significant correlativity between the patient's confident degree VAS and the pain VAS change rate before and after the treatment (R = 0.62, P = 0.83).

CONCLUSIONThere is no significant correlativity between the confident degree of the patient of pain in acupuncture and moxibustion and clinical therapeutic effect.

Sodium houttuyfonate (SH) is a derivative of effective component of a Chinese material medica, Houttuynia cordata, which is applied in anti-infection of microorganism. But, the antimicrobial mechanisms of SH still remain unclear. Here, we firstly discovered that SH effectively inhibits the three types of virulence related motility of.Pseudomonas aeruginosa, i.e., swimming, twitching and swarming. The plate assay results showed that the inhibitory action of SH against swimming and twitching in 24 h and swarming in 48 h is dose-dependent; and bacteria nearly lost all of the motile activities under the concentration of 1 x minimum inhibitory concentration (MIC) (512 mg x L(-1) same as azithromycin positive group (1 x MIC, 16 mg x L(-1)). Furthermore, we found that the expression of structural gene flgB and pilG is down-regulated by SH, which implies that inhibitory mechanism of SH against motility of P. aeruginosa may be due to the inhibition of flagella and pili bioformation of P. aeruginosa by SR Therefore, our presented results firstly demonstrate that SH effectively inhibits the motility activities of P. aeruginosa, and suggest that SH could be a promising antipseudomonas agents in clinic.
