Objective To explore the effects of lamotrigine on the cognitive function and the quality of life in epilepsy patients.Methods This was a prospective study and 91 newly diagnosed epilepsy patients were enrolled.The neuropsychological tests score and the quality of life in epilepsy inventory(QOLIE-31) were obtained before and after the treatment with lamotrigine.A battery of neuropsychological tests comprised the auditory verbal learning test(AVLT), the logical memory test(LMT), the digital symbol test(DST), the stroop color word test(SCWT), the trail making test(TMT), the verbal fluency test(VFT), the WAIS block design test(WBDT), the WAIS digital span test(WDST)and the Boston naming test(BNT). Results The repeated assessments in the patients taking lamotrigine were associated with significant improvements in many domains.The greatest changes were observed in the immediate and delayed recall of AVLT, DST, the time consuming of SCWT card C and TMT test A and B, the immediate and delayed recall of LMT, VFT, WBDT and BNT.For the quality of life, significant improvements were recorded in the fields of the seizure worry(38.81?16.06 vs 45.68?15.18), the overall quality of life(59.12?13.50 vs 64.99?13.33), the social function(64.59?25.14 vs 69.41?22.70)and the self-health evaluation (71.18?13.73 vs 76.75?11.30).Conclusion Improvements of the cognitive function and the quality of life can be observed in the initial period of medication with lamotrigine in epilepsy patients.

Objective To study the effect of Chinese wild rice diet on lipid metabolism in rats. Method Forty four male SD rats were divided into 4 groups:control group, high lipid group, white rice-flour group and Chinese wild rice group. All groups were given different experimental diets for 8 w and body weights, serum TC, TG, HDL-C, high sensitive C-reactive protein (hs-CRP), TNF-? and IL-6 were measured. Results The hyperlipidemic rat model was successfully induced. When compared with high lipid group and white rice-flour diet group, serum TG and TC contents were significantly decreased, and HDL-C significantly increased in the Chinese wild rice group. Moreover, Chinese wild rice group had lower contents of serum hs-CRP and TNF-? than those in high lipid group and white rice-flour group, but no effect on serum IL-6. Conclusion Chinese wild rice could improve lipid metabolism and low-grade inflammation of hyperlipidemic rats induced by high lipid diet.

Objective: To evaluate the quality status of recombinant human interferon α2a injections and find out some quality problems. Methods:The statutory testing methods combining with the exploratory studies were used to examine the samples, and the quality status of recombinant human interferon α2a injections was evaluated by statistical analysis of the results. Results: All 28 bat-ches of the injections were qualified using the statutory testing methods. The exploratory studies showed that if the specific activity was determined, the qualified rate was only 87. 0%. All 7 batches of drug substances were qualified using the statutory testing methods. The exploratory studies showed that if the related protein was determined, the qualified rate was 57. 1%. Conclusion:At present the quality of recombinant human interferonα2a injections is generally good. The current standards are feasible;however, improvement is still needed. Specific activity determination should be supplemented the standards for drug products and related protein determination should be supplemented the standards of drug substances.

OBJECTIVETo observe the survival of hand allograft under the state of immunosuppression and the pathological changes of rejection in the recovery process.

METHODSThe biopsies of the skin, nerve, muscle, tendon and bone tissue of hand allografts during different stages from 1 day to 7 months after operation were observed using routine histological technique.

RESULTSNo significant changes due to rejection in skin, nerve, muscle and bone tissue were observed. But different degrees of weak rejective changes were found on the wall of blood vessels; in the muscle and nerve the reactions were markedly stronger than those found in skin tissues.

CONCLUSIONSThe rejection in deep tissues should be monitored in controlling the rejection of hand allograft.

Dexmedetomidine , a strong potent and highly selective α2 -adrenoceptor agonist , has an analgesic and dose -dependent sedative property with minimal effects on respiratory depression.It is the only tranquilizing drug which can be arousal currently and is also widely used in clinical applications because of its special pharmacologic characteris-tics.However, dexmedetomidine has large individual differences which made the control of administration dosage more difficult , especially in special populations.So this review article summarized the latest litera-tures about pharmacokinetics of dexmedetomidine in children , the elder-ly , hepatic and renal insufficiency patients and other special populations.

OBJECTIVETo evaluate the clinical effect and side-effect of interferon-alpha (IFN-a) and ribavirin (RBV) combination therapy for Chinese patients with co-infection of hepatitis C virus (HCV) and human immunodeficiency virus (HIV), and to compare them with only HIV infection patients.

METHODS10 patients with HCV-HIV and 17 patients with only HCV infection received 5 million units of IFNalpha-2b every other day intramuscularly, and 300 mg RBV orally three times a day. Dynamic observations were done for HCV RNA and HIV RNA loads, CD4+ and CD8+ T lymphocyte counts, liver function and blood cell measures, and the side-effects of the medicines.

RESULTSAfter 12 weeks and 24 weeks of IFNalpha and RBV combination therapy, mean HCV RNA levels reduced 1.14 log (t = 3.843, P < 0.01) and 2.08 log (t =6.564, P < 0.01) from the baseline at week 0 in the HCV-HIV co-infection group, and reduced 1.48 log (t = 6.438, P less than 0.01) and 2.33 log (t = 7.343, P < 0.01) in the HCV infection group. Meanwhile, the HIV RNA levels decreased 1.22 log (t = 3.662, P < 0.01) and 1.73 log (t = 6.119, P < 0.01) from the base line. However, there were no obvious different changes among T lymphocyte counts of HCV-HIV and HCV patients at week 0, week 12 and week 24. All 27 patients showed satisfactory biochemical response to therapy. There were some mild or moderate influenza-like symptoms, intestinal discomfort and decreased blood cell counts in the early stages of the treatments. No neuropsychic and auto-immune disorders were found.

CONCLUSIONSIFNalpha-2b and RBV combination therapy showed similar anti-HCV effects during the 24 week treatment for HCV-HIV and HCV infected patients, and some anti-HIV effect was also observed. No obvious different biochemical responses and side-effects were found between the above two groups.

OBJECTIVETo define the anatomical approach, anatomical planes and related vessels and nerves to create a safe and reproducible combined sublingual and bi-vestibular access for trans-oral video-assisted thyroidectomy.

METHODSFrom November 2009 to May 2011, twenty-five embalmed human specimens were dissected for anatomical information of the cervical region, the mandible region and the supra-hyoid muscles. On twenty fresh frozen human specimens after an experimental trans-oral endoscopic thyroidectomy, the related vascular, neural structures and muscles were evaluated.

RESULTSThe optical access port was placed in the midline sublingual. The geniohyoid muscle, mylohyoid muscle and the anterior belly of the digastric muscle were divided in the midline in order to reach the plane under the platysma muscle. The mucosa was sagittal incised bilaterally in the vestibular of oral cavity for working trocar, at the level of the first molar of the mandible. The working trocar reached directly the periosteum of the mandible, under the facial vessel and the marginal branch of facial nerve, and then passed below the platysma muscle into the infra-laryngeal working area. The distance from mental nerve to mandibular midline and between mental nerve and facial artery were (25.8 ± 0.9) mm and (29.4 ± 0.9) mm respectively. Anatomical dissections showed that after an experimental trans-oral combined sublingual and bi-vestibular access, all muscles of the floor of the oral cavity as well as the related vascular and neural structures are intact. The maximum nodule size of the resected specimens in the totally trans-oral approach was up to 50 mm.

CONCLUSIONThe combined sublingual and bi-vestibular access of trans-oral video-assisted thyroidectomy is safe and reproducible.

BACKGROUNDPrevious prognosis analyses of colorectal cancer (CRC) patients with stage II and III disease were done as separate categories. The purpose of this study was to analyze prognostic factors associated with survival in a group of patients who underwent radical resection of stages II and III CRC.

METHODSA retrospective review was performed for 141 consecutive stages II and III patients who had undergone radical resection of colorectal adenocarcinoma between May 2003 and November 2003. Univariate and multivariate analyses were performed to assess the effect of record variables on disease free survival and overall survival.

RESULTSThe median follow-up time was 59 months, and the 3- and 5-year survival rates were 76% and 68%, respectively. Four factors were independently associated with a worse disease-free survival: diabetes (hazard ratio (HR) 2.338; 95% confidence interval (CI) 1.011 - 5.407), expression of cyclooxygenase-2 (Cox-2) (HR 0.335; 95%CI 0.126 - 0.888), expression of matrix metalloproteinases 2 (MMP-2) (HR 0.233; 95%CI 0.101 - 0.541), expression of vascular endothelial growth factor (VEGF) (HR 0.295; 95%CI 0.088 - 0.996). Four factors were independently associated with a worse overall survival: lymph nodes metastasis (HR 1.67; 95%CI 1.29 - 2.14), Cox-2 positive (HR 0.056; 95%CI 0.247 - 0.731), MMP-2 positive (HR 0.398; 95%CI 0.190 - 0.836), VEGF (HR 0.364; 95%CI 0.090 - 0.716).

CONCLUSIONSDiabetes, expression of Cox-2, MMP-2 and VEGF were independently associated with a worse disease- free survival. Lymph nodes metastasis, expression of Cox-2, MMP-2 and high level of VEGF predicted a poor overall survival.
