Objective To investigate the reversal effect of vitamin D on drug resistance leukemia cell lines Jurcat vitamin D/ADR,K562/ADR and its mechanism.Methods Non-toxic concentration of vitamin D was chosen by methyl thiazolyl tetrazolium,and on line concentration experiment ;the contents of vitamin D for soft erythromycin in the cell and the cell surface of P-glycoprotein(P-gp) expression level were detected by using flow cytometry instrument and vitamin D for intracellular mdr1 mRNA and mrp1 mRNA expression was detected by Real-time polymerase chain reaction;vitamin D for the change of intra cellular glutathione glycosides peptide (GSH) content was detected by adoping biochemistry method.Results Resistance reversal in experiments showed that vitamin D could decrease soft erythromycin in the accumulation of drug resistant cells,with a dose-dependent relationship; vitamin D treatment Jurcat/ADR,K562/ADR cells after 48 h,chemotherapy drugs could increase the cell concentration,and reduce P-gp and the expression of mdr1 and mrp1 gene ; vitamin D treatment Jurcat/ADR,K562/ADR after 48 h could decrease the intracellular GSH content in K562,K562/ADR,Jurcat and Jurcat/ADR.Conclusions Vitamin D has the drug resistance reversal agents to Jurcat/ADR,K562/ADR,which might be relevant to the inhibition of cell surface of P-gp proteins function and expression and reduction of the mdr1 and mrp1 expressions of resistance genes and reduction of intracellular GSH content.Vitamin D by influencing the above mechanism,which increases the drug concentration in cells,can effectively kill the tumor cells.

Objective: To investigate the efficacy of progesterone tablets in the patients with unexplained recurrent spontaneous abortion and the influence on cellular immunity factor.Methods: Totally 90 cases of unexplained recurrent spontaneous abortion patients were randomly divided into the observation group and the control group (45 ones in each).After pregnancy, the control group was given intramuscular injection of human chorionic gonadotropin, and the observation group started to be treated with progesterone tablets on the 35th day after menolipsis.The levels of interleukin-4 (IL-4), interleukin-10 (IL-10), interleukin-17 (IL-17) and IFN-γ were determined, and the expression of T helper lymphocytes (Th17/CD4+), regulatory T lymphocytes (Treg/CD4+) and T helper lymphocytes regulatory T lymphocytes (Th17/Treg) was compared before and after the treatment.The pregnancy success rate and abortion rate were compared between the groups after the treatment, and adverse reactions were also observed.Results: After the treatment, the expression levels of IL-4 and IL-10 in the observation group were higher than those in the control group, and the expression levels of IL-17 in the observation group was lower than that in the control group, and the differences between the groups were significant (P＜0.05);after the treatment, the expression of Th17/CD4+ and Th17/Treg in the two groups decreased, and that in the observation group was lower than that in the control group;after the treatment, the expression of Treg/CD4+ in the two groups increased, and that in the observation group was higher than that in the control group, and the difference was significant (P＜0.05);after the treatment, the expression of IFN-γ in the two groups decreased, and that in the observation group was lower than that in the control group;after the treatment, the pregnancy rate in the observation group was higher than that in the control group with lower abortion rate, and the differences were statistically significant (P＜0.05).The incidence of adverse reactions in the observation group was lower than that in the control group(P＜0.05).Conclusion: Progesterone tablets in the treatment of unexplained recurrent abortion patients show significant effects, and can effectively improve the cellular immune factor in the patients, which is worth promoted application in clinics.

Patients with bilateral nasal vestibule area swelling of 1 week, no obvious pain and symptoms of nasal congestion, bilateral nasal vestibule area was highly uplifted, nostril was significantly smaller, both sides existed a palpable 2. 0 cm × 2. 2 cm and 2. 0 cm × 2. 0 cm cystic mass. Ultrasound showed both sides of the nasal bonehad cystic lesions. Sinus CT showed local quasicircular soft tissue shadow at the bottom of bilateral piriform aperture. The postoperative pathology report: the cystiform tissue is covered with squamous epithelium, infiltration of inflammatory cells could be seen and is consistent with the diagnosis of bilateral nasalvestibular cyst.

OBJECTIVETo compare the efficacy difference in treatment of borderline hypertension between acupuncture combined with anti-hypertensive plaster and simple acupuncture.

METHODSSixty patients of borderline hypertension were randomized into an observation group and a control group, 30 cases in each one. In the observation group, acupuncture was applied to Fengchi (GB 20), Taichong (LR 3) and the others, once a day, 5 treatments made one session. There were 2 days at interval among the sessions. Totally, 4 sessions were required. Additionally, in combination, the anti-hypertensive plaster was prepared with the fine powder of Chuanxiong (ligusticum wallichii) and Wuzhuyu (fructus evodiae) at 1.1 and mixed with vinegar. The plaster was applied to the umbilicus, once every two days, totally 15 times were required. In the control group, acupuncture was given simply. The selected acupoints and operation were the same as the observation group. Before and after treatment, blood pressure and syndrome score were observed and the short-term and long-term efficacies were assessed in the two groups.

RESULTSAfter treatment, the systolic pressure and diastolic pressure were reduced as compared with those before treatment in the two groups (all P<0.001), and the differences were significant in comparison between the observation group and the control group (P<0.01, P<0.05). The syndrome score after treatment was reduced as compared with that before treatment in the two groups (both P<0.001) and the difference was not significant in comparison between the two groups (P>0.05). In follow-up of the effective cases and remarkably effective cases in 3 months, the total effective rate in the observation group was 89.3% (25/28) and was 60.0% (15/25) in the control group, indicating the significant difference in comparison (P<0.05).

CONCLUSIONAcupuncture combined with anti-hypertensive plaster is the effective method in prevention and treatment of borderline hypertension. Regarding the long-term efficacy, this combined therapy achieves the superior improvement in the symptoms and physical signs of the patients of borderline hypertension as compared with simple acupuncture.

OBJECTIVE:To select the formula,preparation and quality evaluation of water-in-oil microemulsion. METHODS:Water-in-oil micromulsion has been formulated using Volp-5 as surfactant, several short chain alcohols as co-surfactants, and the different oils, pseudoternary phase diagrams have been constructed to evaluate the phase behavior of the formulations of the water-in-oil microemulsion, and the influence of mixing ratio of various elements on the area of microemulsion was also examined. The morphology, particle size, distribution and stability was assessed. RESULTS:The stable water-in-oil microemulsion was made. The microemulsion delivery could be prepared using Volp-5/ethanol/caprylic-capric-triglyceride/water (3∶2∶2∶4)system and no phase separation was observed in three months. CONCLUSION:The formulation provide a convenient means of the oral delivery taking advantage of microemulsion's merit, which is easy to prepare with consistent quality.

Objective To explore whether pravastatin protects endothelium against the damage induced by homocysteine (Hcy) in isolated rabbit aorta. Methods Endothelium-dependent relaxation responses to acetylcholine (ACh) of thoracic aortic rings were measured by isometric tension recording before and after aortic rings exposed to Hcy in the absence or presence of pravastatin (PT) to estimate the injury effect of Hcy and the protective effect of pravatatin on rabbit aortic endothelium, respectively. Results Incubation of aortic rings with 1～10mmol/L Hcy for 30min significantly inhibited endothelium-dependent relaxation response to ACh of aortic rings in a concentration-dependent manner. Pre-incubation of aortic rings with 0.3～3mmol/L PT for 15min and co-incubation of aortic rings with 3mmol/L Hcy for another 30min markedly attenuated the inhibition of endothelium-dependent relaxation induced by Hcy in a concentration-dependent manner. Conclusion Pravastatin can improve the impairment of endothelium-dependent relaxation induced by Hcy in isolated rabbit aorta.
