AIM To establish the hyperlipidemia and hyperlipidemic fatty liver animal model.METHODS 30 SD rats were randomized into control group (n=10)and model group(n=20).The rats of model group were fed with a standard diet and fat emulsion( 10 ml?kg -1);while the rats of control group were only fed with a standard diet.The serum TG,TC,ALT,AST,MDA,SOD and hepatic TG,TC,MDA,SOD were detected dynamically and with histologically.RESULTS The model group developed hyperlipidemia which TG and TC were elevated significantly after 1 week. 10 rats which were selected randomly in the model group were killed and the serum and liver were obtained after 2 weeks. The serum TG,TC,ALT and hepatic MDA of the model group rats were higher than the control's,while the hepatic SOD were lower. At the same time,the light degree hepatic steatosis of 2 rats were induced.The third week,both control group and model rats(n=10) were killed and the serum and the liver were obtained. Compared with the control group, the serum TG,TC,ALT,AST,MDA?SOD and hepatic TG,MDA of the model group rats were markedly higher, while the serum SOD and the hepatic SOD were significantly lower.The histopathology research showed hepatocellular macrovesicular steatosis and hepatitis in the model group. CONCLUSINOS The experimental animal model of hyperlipidemia and hyperlipidemic fatty liver in rats were successfully established for 1 week and 3 weeks fed with fat emulsion.

BACKGROUNDAspermia caused by exogenous testosterone limit its usage in late-onset hypogonadism (LOH) patients desiring fertility. Saikokaryukotsuboreito (SKRBT) is reported to improve serum testosterone and relieve LOH-related symptoms. However, it is unclear whether SKRBT affects fertility. We aimed to examine the effects of SKRBT on spermatogenesis and fertility in aging male mice.
METHODSThirty aging male mice were randomly assigned to three groups. Mice were orally administered with phosphate-buffer solution or SKRBT (300 mg/kg, daily) or received testosterone by subcutaneous injections (10 mg/kg, every 3 days). Thirty days later, each male mouse was mated with two female mice. All animals were sacrificed at the end of 90 days. Intratesticular testosterone (ITT) levels, quality of sperm, expression of synaptonemal complex protein 3 (SYCP3), and fertility were assayed.
RESULTSIn the SKRBT-treated group, ITT, quality of sperm, and expression of SYCP3 were all improved compared with the control group (ITT: 85.50 ± 12.31 ng/g vs. 74.10 ± 11.45 ng/g, P = 0.027; sperm number: [14.94 ± 4.63] × 106 cells/ml vs. [8.79 ± 4.38] × 106 cells/ml, P = 0.002; sperm motility: 43.16 ± 9.93% vs. 33.51 ± 6.98%, P = 0.015; the number of SYCP3-positive cells/tubule: 77.50 ± 11.01 ng/ml vs. 49.30 ± 8.73 ng/ml, P < 0.001; the expression of SYCP3 protein: 1.23 ± 0.09 vs. 0.84 ± 0.10, P < 0.001), but fertility was not significantly changed (P > 0.05, respectively). In the testosterone-treated group, ITT, quality of sperm, and expression of SYCP3 were markedly lower than the control group (ITT: 59.00 ± 8.67, P = 0.005; sperm number: [4.34 ± 2.45] × 106 cells/ml, P = 0.018; sperm motility: 19.53 ± 7.69%, P = 0.001; the number of SYCP3-positive cells/tubule: 30.00 ± 11.28, P < 0.001; the percentage of SYCP3-positive tubules/section 71.98 ± 8.88%, P = 0.001; the expression of SYCP3 protein: 0.71 ± 0.09, P < 0.001), and fertility was also suppressed (P < 0.05, respectively).
CONCLUSIONSKRBT had no adverse effect on fertility potential in aging male mice.

BACKGROUNDCoflex, a type of interspinous process implant, can provide intervertebral dynamic stability for surgical segments and effectively relieve lumbocrural pain. However, few studies have described therapeutic strategies and the avoidance of Coflex implant complications.
METHODSCoflex implant complications in this study included intraoperative or postoperative spinous process fracture, aggravated postoperative lumbocrural pain, dislodgment and malposition. The complications were analyzed, and therapeutic strategies were applied according to the specific complication. The Visual Analogue Scale and Oswestry Disability Index scores were evaluated by using the paired-samples test from SPSS 12.0.
RESULTSConservative treatment was provided to seven patients who experienced aggravated lumbocrural pain even though their devices remained in the correct position, and pedicle screw treatment was used as an alternative in four cases. The Visual Analogue Scale and Oswestry Disability Index scores showed evident improvement in these patients. The Visual Analogue Scale and Oswestry Disability Index scores of two patients who underwent revision were also improved.
CONCLUSIONSCoflex implants should be avoided in patients with osteoporosis, a narrow interspinous space and intervertebral coronal spondylolysis, or sagittal instability. Furthermore the device choice, depth of implantation, and clamping intensity should be appropriate. Conservative treatment can be provided to patients with symptoms if the device remains in the correct position; however, revisions and salvages should be undertaken with internal fixation of pedicle screws for patients with device malposition, intraoperative implantation failure, or device intolerance.

Abstract: Our previous work revealed berberine can significantly enhance the susceptibility of fluconazole against fluconazole-resistant Candida albicans, which suggested that berberine has synergistic antifungal activity with fluconazole. Preliminary SAR of berberine needs to be studied for the possibility of investigating its target and SAR, improving its drug-likeness, and exploring new scaffold. In this work, 13-substitutited benzyl berberine derivatives and N-benzyl isoquinoline analogues were synthesized and characterized by 1H NMR and MS. Their synergetic activity with fluconazole against fluconazole-resistant Candida albicans was evaluated in vitro. The 13-substitutited benzyl berberine derivatives 1a-1e exhibited comparable activity to berberine, which suggested that the introduction of functional groups to C-13 can maintain its activity. The N-benzyl isoquinolines, which were designed as analogues of berberine with its D ring opened, exhibited lower activity than berberine. However, compound 2b, 2c, and 4b showed moderate activity, which indicated that berberine may be deconstructed to new scaffold with synergistic antifungal activity with fluconazole. The results of our research may be helpful to the SAR studies on its other biological activities.

This paper contains the results of cl inical studies with 0.1 and 0.15 Tesla KAIS NMR Tomograph which was developed by Korea Advanced 1 nstitute of 5cience. A variety of imaging modes such as saturation recovery(SR), spin echo(SE), and inversion recovery(SR) as well as echo and repetition times were applied. Clinical imagings were performed on 22 patients with dlseases of brain (15 cases), cervical spine(2 cases}, chest (2 cases), pancreas (2 cases), and kidney (1 case). In SR imaglng, we have obtained images strongly dependent on the hydrogen nuclei density. SE with long echo time and IR are effective for T2 and T1 dependent images, respectively. Results of clinical NMR imaging are presented and compared with X-CT and the other radiological examinations. Obtained results appear promising and with further examinations along with parameter adjustment, it is expected that the NMR imaging will not only substitute many conventional diagnostic methods such as X.ray CT but also be useful for the early detection of tumor and other lesions not obtainable with other modalities.

Objective To explore the relationship between NF-kB1-94ins/delATTG gene polymorphism and acute progressive cerebral infarction(APCD ofChinese Hart population in Qingdaodistrict Methods We detected the polymorphism of NF-κB1 -94ins/delA TTG gene in 100 patients with acute cerebral infarction (ACI group) and 99 patients with acute progressive cerebral infarction (APCI group) by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP)analysis. The changes of expression of NF-κBp65 in PBMC cellular nucleus in the 2 groups were detected by cell immunohistochemistry. Results The frequency of TT genetype and T allele in the APCI group was significantly higher than that in the ACI group (P<0.05). Analysis on the relative risk of allele frequency showed that patients with T allele had 1.622 times of risk in having APCI than patients with C allele; logistic regressive analysis indicated that NF-κB1 TT genotype was independently related to the attacking of APCI (OR=2.14, 95% CI: 2.654-8.296, P<0.05). The expressions of NF-κBp65 of PBMC cellular nucleus of TT genotypic individuals in APCI group were significantly higher than those in ACI group (P<0.05); logistic regressive analysis indicated that the expressions of NF-KBp65 in PBMC cellular nucleus of TT genotypic individuals were independently related to the attacking of APCI (OR=1.96; 95% CI: 2.267-7.691; P<0.05). Conclusion The NF-κB1 gene polymorphism might participate in the onset of APCI and T allele of NF-κB1 gene might be a genetic risk factor of getting APCI for Chinese Han populations in Qingdao district. The NF-κB1 T allele carrier might increase the happening of APCI through up regulating the expression of NF-kB1.

OBJECTIVETo investigate device implanted complications and corresponding therapeutic strategies of Coflex interspinous dynamic stabilization system for lumbar spine intraoperatively and postoperatively.
METHODSFrom September 2008 to August 2010, 133 cases of degenerative disease of lumbar spine including 62 males and 71 females, ranging from 35 to 81 years of age (mean 60.8 years), underwent or planed to be underwent decompression with Coflex interspinous dynamic stabilization system were reviewed retrospectively, and 13 cases including 6 males and 7 females, ranging from 41 to 71 years of age (mean 58.6 years), occurred device implanted complications. The Coflex implanted complications were analyzed, and therapeutic strategies according to different character were carried out, scores of visual analogue scale (VAS), Oswestry disability index(ODI) and effect-related data preoperatively, postoperatively, after conservative treatment and in final follow-up were evaluated with paired-samples t test.
RESULTSThirteen cases of Coflex implanted complications and treatment applied included: 3 cases occurred fracture of spinous processes intraoperatively were treated by pedicle screws instead; 2 cases occurred fracture of spinous processes postoperatively or during follow-up, including 1 case underwent revision with pedicle screws, another 1 case treated with conservative treatment; 4 cases with degenerative coronal spondylolysis in surgical segments, 1 case with sagittal instability preoperatively, and 1 case with device dislodgment in follow-up all suffered aggravated pain and received conservative treatment; 1 case suffered implanted malposition intraoperatively was underwent internal fixation with pedicle screws instead; at length, 1 case with aggravated pain postoperatively and without definite reason received revision with internal fixation of pedicle screws demolishing the Coflex. The follow-up time of 13 cases ranged from 20 to 38 months (mean 27.6 months); and 7 cases implanted Coflex with aggravated pain of lumbar and lower limb, but the position of device can still maintained, were received conservative treatment, and whose score of VAS and ODI in the final follow-up were 1.9 ± 0.7 and 23.2 ± 3.4, and comparing to 6.1 ± 1.1 and 58.1 ± 3.0 preoperatively, evident improvement was got finally (t = 8.2 and 18.2, P < 0.01). Scores of VAS and ODI of 2 cases with Coflex implanted complications underwent revision with pedicle screws were also improved correspondingly.
CONCLUSIONSCoflex interspinous dynamic stabilization system implanted should be avoided to cases who suffered with osteoporosis, too narrow interspinous space and intervertebral coronal spondylolysis or sagittal instability; and choice of device, depth of implantation and intensity of clumping should be appropriate. For patients with symptom but device still in right position, conservative treatment can be carried out; but for patients subjected to malposition of device, failure of implantation intraoperatively or intolerance to device, revisions and salvages should be underwent with internal fixation of pedicle screws.
