Semen Cuscutae is a kidney-essence invigorating Chinese drug which is widely used in the clinic. In this study, the effects of the flavonoids extracted from Semen Cuscutae (FSC) on the function of the hypothalamus-pituitary-gonads axis in animals was investigated. The results showed that FSC can increase the weight of uterus and promoted the cornification of vaginal epithelial cells in bilateral ovariectomized mice, which suggested that FSC may have estrogen-like activity. In normal female rats, it increased the weight of pituitary, ovary and uterus, but did not increase plasma luteinizing hormone (LH) level. The binding capacity of ovary to 125 I-HCG/LH receptor was significantly elevated the reactivity of luteinizing-releasing hormone (LRH) was increased, and the LRH-induced LH secretion was enhanced in ovariectomized rats. In immature male mice, FSC increased the weight of epididymis and testis, and stimulated HCG-induced secretion of testosterone in short-term cultured rat Leydig cells. It is suggested that FSC can improve the functions of reproductive and endocrine system.

Objective To evaluate the therapeutic effect of glycyrrhizic acid ointment on chronic eczema in guinea pigs.Methods Totally,60 Kunming male mice,60 Kunming mice and 60 albino guinea pigs were respectively classified into 6 groups:model group,ointment base group,dexamethasone group,high-,medium-and low-dose glycyrrhizic acid group.To observe the effect of glycyrrhizic acid ointment on the swelling of mouse auricles,dexamethasone and different doses of glycyrrhizic acid ointment were topically applied to both auricles of male mice in corresponding groups followed by the establishement of mouse auricle swelling model induced by xylene.One and a half hours later,the mice were sacrificed,and the weight of swelling auricles was weighed.Scratching behavior was induced by dextran 40 in Kunming mice following the application of dexamethasone or glycyrrhizic acid ointment.The latent period and frequency of scraching were recorded for every Kunming mice.To establish a model of eczema,guinea pigs were sensitized with dinitrochlorobenzene (DNCB,5％) in the neck and back and challenged by DNCB (0.1％) on the inner surface of right ears once a week for 4 weeks;subsequently,both auricles were treated with dexamethasone or glycyrrhizic acid ointment once a day for 10 days.Then,the thickness of auricles of guinea pigs was measured,and skin tissue was obtained from the right ear of guinea pigs and subjected to a pathological analysis.Results The high- and medium-dose of glycyrrhizic acid ointment could suppress the xylene-induced swelling of mouse auricles (P ＜ 0.05 or P ＜ 0.01 ).The latent period of scratching could be lengthened by high dose of glycyrrhizic acid (P ＜ 0.05).The three doses of glycyrrhizic acid all reduced scratching frequency in Kunming mice (P ＜ 0.05 or P ＜ 0.01 ).Attenuated swelling of auricles (P ＜ 0.05 or P ＜ 0.01 ) and relieved pathological changes were observed in guinea pigs after treatment with glycyrrhizic acid ointment.Conclusion Glycyrrhizic acid ointment shows a therapeutic effect on chronic eczema in guinea pigs.

Objective To investigate the change characteristics of serum ferritin(SF)and parathormone (PTH)levels in differ-ent stages of chronic kidney disease(CKD)and their correlation with serum beta 2-microglobulin(β2-MG).Methods The levels of serum PTH,SF andβ2-MG in different stages of CKD were detected and the detection results were compared with those in the con-trol group.The correlation between serum SF and PTH withβ2-MG in each stage of CKD was analyzed.Results The level of ser-um PTH,SF andβ2-MG in the compensation group had no statistical difference compared with the control group (P >0.05),while which had statistical differences among the decompensation group,renal failure group and uremia group (P <0.05)The correlation analysis showed that serum PTH was positively correlated with serumβ2-MG in 145 cases(r=0.92,P <0.05),and the serum SF level was also positively correlated with serumβ2-MG level(r=0.92,P <0.05).Conclusion Detecting serum PTH,SF andβ2-MG levels possesses the important clinical significance for understanding CKD condition and prognosis.

Objective:To study the preparation technique for magnetic poly D,L-lactide-co-glycolide phenylarsine oxide nanoparticles (M-PLGA-PAO-NPs) and to characterize the resultant product. Methods: M-PLGA-PAO-NPs were prepared by using emulsion-evaporation process. The morphology of the prepared nanoparticles were observed by transmission electron microscope and the magnetism of the particles was determined by vibrating sample magnetometer. Meanwhile, we also evaluated the mean diameter, encapsulation ratio, and drug loading rate of the particles. Results: The nanoparticles had a regular spherical surface, with 80% of them having a diameter of 140-500 nm. We also found that the drug loading rate of the particles was 3.2% and the mean encapsulation ratio was 34.2%. The drug had satisfactory magnetic property. Conclusion: Our method can obtain M-PLGA-PAO-NP with satisfactory quality, it is simple-to-use and the prepared particles can meet the requirement of pharmaceutics.

Objective To analyse the expression of alpha-fetoprotein variant-L3(AFP-L3)and glypican-3(GPC-3)in primary he-patic carcinoma(PHC)with different concentration of alpha-fetoprotein (AFP),so as to provide references for the diagnosis of PHC.Methods 240 cases of outpatients,inpatients and individuals on physical examination were selected as subjects and serum levels of AFP-L3 and GPC-3 were detected.All of the subjects were divided into negative group(0≤AFP<20 ng/mL),low concen-tration group(20≤AFP<400 ng/mL)and high concentration group(AFP≥400 ng/mL)according to the serum levels of AFP.Ser-um levels of AFP-L3 and GPC-3 were compared among the three groups.And the sensitivity,specificity and accuracy of single de-tection of AFP-L3 or GPC-3 and those of combined detection of AFP-L3 and GPC-3 were compared as well.Results The serum levels of AFP-L3 and GPC-3 in the low concentration group and high concentration group were both higher than those in the nega-tive group,and those in the high concentration group were also higher than those in the low concentration group,had statistically significant differences(P < 0.05 ).The sensitivity,specificity and accuracy of combined detection of AFP-L3 and GPC-3 were 84.4%,95.9% and 93.8% respectively,which were higher than those of single detection of AFP-L3 or GPC-3.Conclusion Com-bined detection of AFP-L3 and GPC-3 could improve the sensitivity,specificity and accuracy for diagnosis of PHC,which has clinical significance for the diagnosis of PHC.

Objective To set up the rolling circle amplification (RCA) system for detecting hepatitis B virus (HBV) covalently closed circular DNA (cccDNA), and to evaluate the specificity and sensitivity of this system. Methods Plasmids containing full-length of wild-type HBV genome were treated with restriction enzyme and T4 DNA ligase, and then were concentrated. The DNA fragments were recovered by the nucleic acid purification kit and severed as standard HBV cccDNA. Total DNA was extracted from hepatic tissues of seven chronic hepatitis B patients. RCA method was used to amplify genomes from tissue samples. Standard HBV cccDNA, 3.2 kb liner HBV DNA, normal hepatic tissue samples and 15 serum samples of patients with chronic HBV infection were used as controls to determine the specificity of RCA. Ten-fold serial dilutions of standard HBV cccDNA were used for determining the sensitivity. Results The standard HBV cccDNA was successfully constructed and could be detected by RCA method. HBV cccDNA could be amplified from 2 mg hepatic tissue samples at least of HBV infected patients, and could be detected as low as 1 ×102 copy/μL. cccDNA was not detected in 3.2 kb liner HBV DNA, normal hepatic tissue samples and 15 serum samples of chronic HBV infected patients. Conclusion RCA method can be used for rapid and simple detection of HBV cccDNA with high specificity and sensitivity.

The purpose of this study was to evaluate the effect and safety of Jinlong capsule combined with chemotherapy or radio-therapy for non-small cell lung cancer (NSCLS) using Meta-analysis. PubMed, Embase, CNKI and Wanfang databases were all searched without language restriction, and searching time was from January 1990 to July 2015. All eligible published studies were included in this study for quality assessment and data extraction. All the data were analyzed using Revman 5.3. A total of ten studies including 736 subjects (370 in Jinlong capsule plus chemoradiotherapy and 366 in chemoradiotherapy only) were finally included in this Meta-analysis. The result of Meta analysis showed that compared with pure chemoradiotherapy group, Jinlong capsule combined with chemoradiotherapy for NSCLC could improve the patients' curative effect (OR = 1.77, 95% CI: 1.29-2.43, P < 0.05), clinical benefit rate (OR = 1.89, 95% CI: 1.22-2.91, P < 0.05), life quality improvement rate (OR = 2. 56, 95% CI: 1.61-4.05, P < 0.05), and decrease leucopenia incidence rate (OR = 0.35, 95% CI: 0. 22-0.56, P < 0.05) and gastrointestinal reaction rate (OR = 0.67, 95% CI: 0.40-1.11, P < 0.05). The pooled results showed that Jinlong capsule combined with chemoradiotherapy for NSCLC could improve the curative effect and life quality, and decrease the adverse reaction of patients.
