Objective To study the physical and chemical properties of silibinin; To lay foundation for optimal formulation design.Methods The high performance liquid chromatography method was used to detect the equilibrium solubility of silibininin in various solutions. The partition coefficients of silibinnin in the n-octalution-water and n-octalution-buffer solution systems were determined by shaking flask method. The destructive tests were carried out on silibinin.Results The equilibrium solubility of silibininin at 25℃ was 1.352 mg/L in water and the largest in acetonitrile, and increased in basic buffer solutions and after adding surfactants, of which sodium dodecyl benzene sulfonate was the strongest in solubilizing ability. The apparent oil-water partition coefficient of silibinnin was 61.39. Silibinnin was unstable in the acidic, basic, oxidizing and reducing solutions.Conclusion The experiment results can provide references for designing new preparations of silibinin.

Objective To explore the relationship between the protective effect of hydrogen sulfide (H2 S ) postconditioning against myocardial hypoxia-reoxygenation and the dynamics of actin. Methods Adult rat cardiomyocytes were isolated and the same hatch cells were divided into 4 groups (n =3):normal group (group N),hypoxia-reoxygenation group (group HR),ischemia postconditioning group (group IPTC)and H2 S postconditioning group (group S).The four groups were divided into two sub-groups with or without cytochalasin D (CyD).At the end of reoxygenation,F-actin/G-actin,intracellular calcium ion concentration (Ca2+ )and pH value were detected with laser scanning confocal microscopy, meanwhile the level of p-p38MAPK was detected with Western blot.Results The fluorescence intensity of F-actin/G-actin of group HR,group IPTC and group S were significantly higher than that of group N (P <0.05).The fluorescence intensity of Ca2+ of group HR was higher than that of group N,group IPTC and group S (P <0.05);The intensity of Ca2+ of all group with CyD treatment was higher than those without (P <0.05);The fluorescence intensity of pHi of group N and group HR with CyD treatment was higher than those without;The fluorescence intensity of pHi of group IPTC and group S was lower than those without;The flu-orescence intensity of pHi of group HR was lower than that of group N,group IPTC and group S (P <0.05), respectively;the pHi of group N and group HR sub-group with CyD treatment was higher than those without correspondingly (P <0.05),however,the pHi of IPTC and S sub-groups were lower than their corresponding groups (P <0.05).The level of p-p38MAPK in group HR was significantly higher than those of other groups (P <0.05);there was no difference among groups N,IPTC and S.Conclusion Hydrogen sulfide postcondi-tioning could promote F-actin to remodel and stabilize the cellular environment.Hypoxia-reoxygenation pro-motes the phosphorylation level of p38MAPK,which could be surpressed by H2 S postconditioning.

A strain no.H5 isolated from Rhizophora stylosa Griff in Zhanjiang had a good antagonistic activity against Aspergillus niger,pathogen of Dracaena Sanderiana black-rot disease.It was identified as Bacillus licheniformis.Dual culture,mycelium growth rate and inhibitory zones were used to test the effect. Strong inhibition was shown against A.niger.Inhibitory ratios of H5 germ-free fermented filtrate on mycelium growth and conidial germination were 91.9%and 100%respectively.In addition,mycelia on the edge of antagonistic band became abnormal and over-branching.Meanwhile,a lot of vesicles appeared on the surface.When treated with heat,acid and alkali,the filtration of H5 was always with stable activity.Precipitate in 55%saturated ammonium sulfate dissolved in phosphate buffer solution maintained most of the activity after high pressure steam sterilization for 25 minutes.It was preliminarily considered as a kind of heat resistant protein.

PURPOSE: This study aimed to explore the protective factors of demoralization in cancer patients via investigation of cancer patients' demographic and disease characteristics. METHODS: This was a cross-sectional descriptive study. We used a structured questionnaire, which contained items on demographic and disease characteristics, as well as the Demoralization Scale Mandarin Version (DS-MV), with a cutoff of 30 or more indicating high demoralization. Data were analyzed with age-matched and gender-matched conditional logistic regression analysis. For the study, 428 questionnaires were delivered and 411 were recovered. After being age-matched and gender-matched, 182 participants of high demoralization (DS-MV > 30) and low demoralization (DS-MV ≤ 30) were obtained respectively, for a total of 364 participants. RESULTS: Cancer patients' demoralization was significantly related to family support (p = .019), education (p = .049), and monthly income (p = .001). Family support [odds ratio = 0.38; p = .028; 95% confidence interval (0.16, 0.91)] and monthly income [odds ratio = 0.49; p = .009; 95% confidence interval (0.29, 0.84)] were protective factors of demoralization in cancer patients. CONCLUSION: Early and appropriate demoralization assessment of cancer patients' demographic and disease characteristics is very important in clinical settings. Healthcare providers might regularly monitor demoralization in cancer patients, and develop related nursing care guidelines or treatment for demoralization in cancer patients. The study results can be a reference for healthcare providers who work with cancer patients.

Oncocytic lipoadenoma is a rare tumor, with only 18 cases having been reported since the first in 1998. We encountered a case of oncocytic lipoadenoma presenting as a slowly growing parotid mass in a 71-year-old man. This tumor is characteristically comprised of a mixture of oncocytes and adipocytes. The present case is one of five reported cases of oncocytic lipoadenoma showing sebaceous differentiation. The results of immunohistochemical study with DOG1 antibody supported the origination of this tumor in the striated duct.

OBJECTIVETo investigate the clinical outcomes of the posterior C1,2 screw-rod combined with C2 unilateral translaminar screw and contralateral pedicle screw fixation and autogenous bicortical iliac crest graft fusion in treating upper cervical instability with vertebral artery variations.

METHODSFrom June 2008 to December 2012, the clinical data of 12 patients with upper cervical instability underwent C1 lateral mass screws-C2 unilateral laminar and contralateral pedicle screws fixation combined with autogenous bicortical iliac crest graft fusion were analyzed retrospectively. There were 8 males and 4 females with a mean age of 47.5 years (ranged, 16 to 77 years). Patients suffered from occipitocervical activity limitation of motion with pain or not, VAS was 0-7 points with an average of (3.50 +/- 2.71) points. Unilateral vertebral artery hypoplasia was demonstrated by vertebral arteriography (VAG) or CTA in all patients. Cervical X-ray and CT scans were done within 7 days after surgery in order to confirm internal fixation position. Internal fixation loosening and breakage, reduction losing, bone fusion ratio were observed during follow-up.

RESULTSNo nerves and vertebral artery injuries occurred during operation. Cervical pain obviously decreased and VAS was (0.92 +/- 0.90) points. Cervical alignment of 12 patients had well-recovered by X-ray while Atlantoaxial ventral lamina cortex of 1 case was encroached by CT scan without neurological symptom. All patients were followed up for 6 months to 3 years, no internal fixation loosening and breakage, reduction losing were found. All patients obtained bone fusion in 6-12 months after operation.

CONCLUSIONPosterior C1 lateral mass screws-C2 unilateral laminar and contralateral pedicle screws fixation combined with autogenous bicortical iliac crest graft fusion can achieve biomechanical stability and raise the successful rate of bone fusion, while avoiding the risk of vertebral artery injury and overcoming the insufficient of bone fusion during bilateral laminar screws placement as well. Posterior C1 lateral mass screws fixation is a safe and effective additional method in treating upper cervical instability with vertebral artery variations.
