Objective To observe the impacts of Ruangan-Lidan Tang on immune function for liver cancer patients receiving TACE combined with 3D conformal radiotherapy, evaluation of short-term efficacy, survival, to explore the changes of cellular immune function in the treatment. Methods 86 cases of liver cancer patients were randomly divided into treatment group and control group were taken in 3D conformal radiotherapy to 50-60GY/5-6 week for fourth weeks after TACE, the treatment group taking Ruangan-Lidan Tang intervention, control group without the use of traditional Chinese medicine intervention.Before the start, after 1 weeks of TACE, within 3 days before radiotherapy,end of radiotherapy, a total of 4 times for T cell differentiation antigen were measured, and between two groups were compared with t test, 2 months after radiotherapy CT or MRI evaluation of curative effect, survival. Results 5 cases of loss of cases, the total cases were 81 patients, including 40 cases of treatment group, 41 cases in After 1 weeks of TACE, CD3+, CD4+, CD8+of the treatment group were (55.15±4.76)%, (31.88±5.50)%, (22.00±3.18)% of the control group were (53.39±5.00)%, (30.49±5.94)%, (23.39±3.41)%. There was no significant difference between two groups (P>0.05); Before radiotherapy, CD3+, CD4+, CD8+ of the treatment group were (59.05±5.91)%, (40.55±6.17)%, (18.63±3.14)%, of the control group were 55.88±4.65%,33.88±4.41%,22.00±3.78%. There was significant difference between two groups(P<0.01);At the end of radiotherapy, CD3+,CD4+,CD8+ of the treatment group were (61.03±5.54)%, (42.65±4.57)%, (18.10±3.20)%, of the control group were (55.56±5.14)%, (32.95±4.01)%, (23.32±2.69)%. There was significant difference between two groups (P<0.01). Short-term efficacy(CR+PR)of the treatment group was higher compared with the control group(82.50%, 75.61%), but no significant difference (U=1.177, P>0.05). In the treatment group, the median survival time was 22 months,the average survival time was 21.7 months, the half year survival rate was (97.5± 2.5)%(39/40);In the control group, the median survival time was 20 months, the average survival time was 19.3 months, the half year survival rate was (94.9±3.5)% (37/41). Follow-up survival analysis, treatment group than in the control group increased, but there was no statistical difference (P=0.132, P>0.05). Conclusion Ruangan-Lidan Tang can improve the immune function of liver cancer patients receiving TACE combined with radiotherapy, but in the Short-term efficacy and survival did not reflect advantage.

OBJECTIVE:To study the effects of Ⅰ,Ⅱ crystal and amorphous forms of lercanidipine hydrochloride on the preparation,and provide theoretical basis for its development and consistency evaluation. METHODS:X-ray powder diffraction (XRD),infrared spectrophotometry(IR)and differential scanning calorimetry(DSC)were adopted to identify the 3 crystal forms of lercanidipine hydrochloride. XRD was used to compare the effects of crushing,grinding,pressing technology,wetting granula-tion,adhesive solvents(water,ethanol)and drying temperature(50,60,70℃)on stability of 3 crystal forms of lercanidipine hy-drochloride;the dissolution in vitro in water,hydrochloride,pH 4.5 acetate buffer,pH 6.8 phosphate buffer were compared among 3 crystal forms of Lercanidipine hydrochloride tablet. RESULTS:XRD showed both Ⅰ,Ⅱ crystal forms had characteristic diffrac-tion peak with inconsistent 2 θ values,amorphous had no characteristic diffraction peak;IR showed 3 crystal forms had different absorption intensity and absorption peak number;DSC showed Ⅰ,Ⅱ crystal forms had obvious endothermic peak in 194.6 ℃, 207.3 ℃,respectively,amorphous had obvious endothermic peak in 86.1 ℃ and exothermic peak in 299.8 ℃. Crushing,grinding, pressing and drying temperature had no effects on the stability of 3 crystal forms;water had no effect on the stability of crystal in wetting granulation,ethanol may cause the change of Ⅰcrystal form. Except for the comparison between Ⅰ,Ⅱ crystal forms in hydrochloride (f2=68),the dissolution f2 of 3 crystal forms in 4 kinds of medium were lower than 50. CONCLUSIONS:XRD, IR,DSC methods can identify the 3 crystal forms of Lercanidipine hydrochloride tablet. When preparing lercanidipine hydrochlo-ride by Ⅰcrystal form,wetting granulation should avoid using ethanol as a adhesive solvent,instead of water. Different crystal forms can affect the dissolution in vitro of prepared Lercanidipine hydrochloride tablet.

Objective To investigate the correlation between the rs13266634 C/T SNP of SLC30A8 and T2DM in Jinzhou. Methods Based on case?control study,PCR?HRM was used to identify the genotypes of rs13266634 of SLC30A8 gene in 136 cases of T2DM patients and 145 cases of healthy control in Jinzhou. Results The CC genotypic frequency and C allele frequency in T2DM(38.23%and 61.76%)were higher than those of healthy control(22.07%and 51.03%). Furthermore,there was significant difference in case?control study from the population in Jinzhou(P<0.05). The odds ratio of allele C for T2DM was 1.550(95%CI:1.108?2.169,P<0.05). Conclusion The single nucleotide polymorphism of the rs13266634 locus in SLC30A8gene was correlated with T2DM susceptibility in Jinzhou,and the allele C was a risk allele.

Objective To investigate the effect of minocycline on isoflurane-induced hippocampal neuroapoptosis and cognitive dysfunction in aged rats. Methods Forty-five male SD rats were randomly assigned into 3 groups ( n=15): blank control group ( group C) , 1.5% isoflurane group ( group I) and 50 mg??kg-1 minocycline+1.5% isoflurane group ( group M+I) . Minocycline was injected intraperitoneally 12 h before the start of anesthesia for group M+I.Group I and group M+I were exposed to 1.5% isoflurane for 4 h, while group C were exposed to 30% O2-70% N2.At the end of anesthesia, five rats in each group were randomized to analyse arterial blood gas. The other rats in each group were sent back to their home cage until they were fully awake.Fourteen days after anesthesia, Morris water maze was used to assess the cognitive function, and then hippocampi of rats were dissected for detection of the expression of cleaved caspase3, Bax and Bcl-2. Results No difference was found in arterial gas analysis among the 3 groups (P>0.05).Compared with group C, the rats in the group I spent more time locating the platform on the third and fourth training days and the time percentage that the rats in group I spent in the target quadrant was much less (P<0.05).However, these changes were reversed in group M+I (P<0.05).The isoflurane-induced increased level of Bax and cleaved caspase3 and decline of anti-apoptotic factor Bcl-2 were restored by minocycline pretreatment ( P<0.05) . Conclusion Minocycline could attenuate cognitive dysfunction induced by isofluranein aged rats.The mechanism is associated with inhibition of hippocampal neuroapoptosis which is increased by isoflurane.

Aim To study the application status of odds ratio for medical animal experiments.Methods Odds ratio and seven kinds of animal models were used as retrieval strategy to search medical animal experiment related papers in several Chinese and English databases.Papers relating to each kind of animal model and using odds ratio in abstract and text were counted. Data from different databases were compared. Calculation of odds ratio was exemplified and the significance of different odds ratio values was illustrated in this paper.Results Few medical animal experiments cited odds ratio as statistics.Conclusions The importance of odds ratio has not been fully recognized in Chinese references.
