The expression of TF-1 cell apoptosis-related gene 19 (TFAR19), a novel apoptosis-related protein, in the thyroid tissues of Hashimoto′s thyroiditis (HT) was investigated. TFAR19 expression was barely detectable in normal thyroid tissues, whereas positive expression was found in the thyrocytes of HT patients. The results suggested that the activation of TFAR19 apoptosis pathway may play an important role in the pathogenesis of HT.

Objective To study formulation and characteristics of self-microemulsifying drug delivery system for breviscapine(BRV-SMEDDS).Methods The optimum formulations of BRV-SMEDDS were screened by solubility tests,formula compatibility,and pseudo-ternary phase diagrams.And the physicochemical characters,dissolution in vitro and in situ rat's intestine absorption of BRV-SMEDDS were also observed.Results The optimum formulation of SMEDDS was composed of Maisine 35-1-Cremophor RH40-PEG400-TEA=25∶40∶35∶7.The particle diameter was 88.6 nm.The percent of accumulated dissolution of BRV in SMEDDS in vitro was up to 97.8% at 1h,which was 8.0 times as much as that of BRV powder,and 5.1 times as BRV tablets.In the tests of in situ rat's intestine absorption,the permeability coefficient of BRV-SMEDDS was increased by 3.4 times as much as BRV powder,and 3.3 times as BRV tablets.Conclusion The dissolution and absorption of BRV is improved by formulation of SMEDDS.It could provide reference for the new dosage form of BRV.

OBJECTIVE: To prepare solid supersaturatable self-emulsifying drug delivery system of vinpocetine(VIN-S-sSEDDS) and to study its characteristics in vitro and in vivo.METHODS: VIN-S-sSEDDS was prepared by spray drying using hydroxypropyl methyl cellulose(HPMC) as supersaturation promoter and dextran-40 as solid carrier.VIN-S-sSEDDS was compared with conventional self-emulsifying drug delivery system containing vinpocetine(VIN-SEDDS) in respects of particle size,in vitro dissolution and bioavailability in rats(ig.).RESULTS: The particle size of VIN-S-sSEDDS(58.78 nm) was smaller than that of VIN-SEDDS(65.12 nm).The accumulative dissolution of VIN-S-sSEDDS within 2 h(88.7%) was higher than that of VIN-SEDDS(58.2%).The bioavailability of VIN-S-sSEDDS in rats(2.30) was higher than that of VIN-SEDDS(1.63).CONCLUSION: Prepared VIN-S-sSEDDS could apparently improve the dissolution and bioavailability of VIN,and it is superior to conventional self-emulsifying preparation.

Objective To investigate heart rate variability(HRV)of senile unstable angina patients complicated with depression and anxiety.Methods 39 senile unstable angina patients with depression and anxiety were selected as the A group,51 patients without depression and anxiety as B group.Their Holter reports(supervision)of two groups were analyzed.Results The SNDD,RMSSD,PNN50 in A group decreased compared with those in B group(P<0.05).The incidence of ventricular arrhythmias,ischemic ST segment depression and HRV in A group was higher than those in B group(P<0.05).Conclusion The senile unstable angina patients with depression and anxiety tend to have more ventricular arrhythmias,ischemic ST segment depression and less HRV.

The protoplasts of original Aspergillus niger strain Uco-3 were treated with the cooperation of UV and ?-ray to obtain the high-yielding strain producing the thermostable ?-galactosidase. Under the optimum conditions of formation and regeneration protoplasts were prepared. According to the interaction of positive mutation rate and radiation dose,the optimum condition was determined. The optimum dose of UV was 4 minutes and the optimum dose of ?-ray was 500 Gy. After mutagenetic treatment of protoplasts and selection from a lot of mutants,a mutant DL116 producing the thermostable ?-galactosidase was obtained. The ?-galactosidase activity of DL116 was increased from 16.27 U/mL to 44.37 U/mL,which was higher than that of strain Uco-3.

OBJECTIVETo observe the effect of alcohol extracts from Pharbitidis Semen on the proliferation and metastasis of Lewis lung cancer, and study its anti-tumor mechanism.

METHODIn vitro, MTT assay and scratch assay were adopted to detect the effect of alcohol extracts from Pharbitidis Semen on the proliferation and metastasis of Lewis lung cancer cells. The cell autophagy was detected by the acridine orange staining. The gap-junction intercellular communication (GJIC) was investigated by the fluorescent yellow transfer. The expression of aquaporin 1 (AQP1) was analyzed by the Western blotting. In vivo, the subcutaneous implant model and the experimental pulmonary metastasis model of Lewis lung cancer in mice were established to evaluate the anti-tumor and anti-metastasis effects of alcohol extract from Pharbitidis Semen. The serum carcinoembryonic antigen (CEA) and beta2 microglobulin (beta2-MG) of mice bearing Lewis lung cancer were detected by the electrochemiluminesence immunoassay. The expressions of lung AQP1 and Connexin 43 (Cx43) were examined by the immunohistochemical method.

RESULTIn vitro, alcohol extracts from Pharbitidis Semen inhibited the cell proliferation in a dose-dependent matter, significantly prevented the cell migration, down-regulated AQP1 proteins of cells, promoted GJIC, and decreased the serum-free autophagy of tumor cells. In vivo, compared with untreated model mice, alcohol extracts from Pharbitidis Semen inhibited the tumor growth in a dose-dependent matter, prevented the tumor metastasis and prolonged the life span of mice bearing Lewis lung cancer, while decreasing serum CEA and beta2-MG of mice bearing Lewis lung cancer, enhancing the immumohistochemical staining intensity of Cx43 and weakening aquaporins AQP1 positive intensity.

CONCLUSIONAlcohol extracts from Pharbitidis Semen could prevent the proliferation and metastasis in Lewis lung cancer cells. Its mechanism may be related to the promotion of GJIC and the down-regulation of AQP1.

0.05).The different tilt angles impacted patients' fear psychology(?2=8.038,P=0.018).The order of the extent of children's fear psychology represented from low to high at the angle of 60?,70? and 80?,respectively.The extent of the children's fear psychology had positive correlation with the tilt angle(r=0.669,P=0.002).Conclusions The tilt test angle does not affect the positive rate of HUTT and the hemodynamics in children undergoing HUTT with angles from 60? to 80?.The children at the tilt angle 60? had less fear than at the angle of 70? or 80?.The 60? tilt angle of HUTT in children is recommended in the clinical practice.

ObjectiveTo evaluate the clinical efficacy and toxicity of gefitinib combined with Zhenqi Fuzheng capsule in treatment of senile non-small-cell lung cancer (NSCLC) at the middle and late stages. Methods88 patients with NSCLC at Ⅲ b-Ⅳ were randomly divided into combined drugs group ( gefitinib combined Zhenqi Fuzheng capsule,n =46 cases) and single drug group (gefitinib,n=42 cases).After treatment for 60 d,the short-term efficacy,side effects and quality of life were observed and evaluated. The objective response and survival rate were assessed after following up for 2 years. Results The short-term efficacy rate in the combined drugs group (19.6 ％ ) was higher than single drug group (11.9 ％ ),but there was no significant difference between the two groups (x2=0.096,P＞0.05).The rate of Karnofsky score in improvement and stableness was 71.7％ in combined drugs group and 50.0％ in single drug group,and quality of life improved after combined drugs compared with single drug treatment (x2 =4.376,P＜0.05).The adverse effects in combined drugs group was some lower than in single drug group with no statistical significance.There was no differences in the survival rates of 2 years between the two groups(x2 =0.556,P＞0.05). ConclusionsThe gefitinib combined Zhenqi Fuzheng capsule in treatment of middle-and late-stage NSCLC is worthy to be popularized due to positive efficacy,less side effects and higher quality of life.
