The development of agency of Pregnancy technique shakes the traditional reproductive ethic and challenges the present law as it brings happiness of being parents to infertile couples.We should not only recognize its rationality,but also alert its potential harnfulness to society and ethic.Reasonably taking advantage of agency of Pregnancy technique and working out relative legislation are two important ways to prevent the corresponding legal and ethical confusion

Background and purpose:Checkpiont targeted immunotherapy in the field of solid tumor therapy has huge potential, triggering a boom in the study of immune targeted drugs. A study has provided a basis for the follow-up study of ipilimumab combined with chemotherapy in the treatment of non-small cell lung cancer(NSCLC) patients. This study counted the adverse event statistics that ipilimumab or placebo combined with paclitaxel and carboplatin as first-line therapy for the treatment of stage Ⅳ or recurrent squamous cell carcinoma to evaluate the safety of ipilimumab combined with chemotherapy in the treatment of advanced squamous cell carcinoma.Methods:This study selected 13 patients with ECOG scores≤1 and stage ⅣA or ⅣB squamous cell carcinoma in the Shanghai Chest Hospital, Shanghai Jiao Tong Uni-versity. Randomized controlled double blind trial was used in this study. The patients of experimental group were treated with ipilimumab combined with paclitaxel and carboplatin, while the patients of control group were treated with the placebo combined with paclitaxel and carboplatin. Adverse events (AEs) were counted in the process of treatment.Results:The most common AEs were the 1/2 grade AEs. Immune-related AEs (irAEs) reported in the ipilimumab group included level Ⅰ of diarrhea and pruritus, level Ⅱ of rash and pruritus and level Ⅲ of hypophysitis.Conclusion:The side effects of ipilimumab were mild, tolerable and manageable.

The change of kirenol, darutigenol and darutoside in Siegesbeckia and its first to ninth processed products were studied, and the ten fingerprints were compared, which provided the experimental basis for the study of Siegesbeckia processing tech- nology. The samples were analysed by HPLC on a SunFire-C18 column (4.6 mm x 150 mm, 5 μm) with gradient elution of acetonitrile (0.1% formic acid)-water (0.1% formic acid) at a flow rate of 1.0 mL x min(-1). Column temperaturewas 30 °C and the detected wavelength was 215, 320 nm. The calibration curves of kirenol, darutigenol and darutoside were linear in the range of 2.180-26.16, 2.900-34.80, and 1.012-6.072 mg x L(-1), respectively, and the average recoveries were 96.4%, 97.2% and 96.3% wit RSD 2.2%, 1.7% and 2.4%.

Objective To compare clinical effect of gonadotropin releasing hormone agonist(GnRH-a) alone and GnRH-a combined with low-dose dydrogesteronea and estradiol valerate on sex hormone, hypoestrogenic symptoms, quality of life and bone mineral density (BMD)in treatment of endometriosis.Methods Seventy patients with moderate or severe endometriosis, who were diagnosed by laparotomy or laparoscopic surgery within two months, were randomly assigned into two groups.35 patients in GnRH-a group were treated by goserelin (3.6 mg)for three months, and 35 patients in add-back group were treated by goserelin (3.6 mg)combined with estradiol valerate 0.5 mg and dydrogesteronea 5 mg daily.Before and after the treatment, clinical parameters were recorded and analyzed, including visual analog scale (VAS), medical outcomes survey short form 36 (SF-36), Kupperman menopausal index(KMI), BMD, the serum level of follicle stimulating hormone (FSH), estradiol (E_2) and bone gla-protein (BGP) .The first menstruation and VAS were also followed up after treatment.Results Every 3 cases in two groups lost follow-up.(1)Reproductive hormone: the level of E_2 in add-back group [(94 ± 71) pmol/L]was significantly higher than (54±52) pmol/L in GnRH-a group(P <0.01).The level of FSH in add-back group [(3.0 ± 1.9) U/L]was significantly lower than (5.7 ± 2.9) U/L in GnRH-a group (P < 0.05).(2) VAS: after treatment, VAS in both group decreased significantly when compared with that before treatment(P < 0.05), and remained until menstruated.(3) KMI: KMI in add back-group (10 ± 8) was significantly lower than (14 ± 6) in GnRH-a group (P < 0.05).(4) BMD: compared with that before treatment, BMD decreased significantly after treatment in GnRH-a group (P < 0.05), no remarkable difference of BMD was observed before and after treatment in add-back group.Before treatment, serum BGP in both groups did not show statistical difference.After treatment, the level of BGP in GnRH-a group [(7932±5206) ng/L]was significantly higher than (5419±2917) ng/L in add-back group (P <0.05).Conclusions GnRH-a combined with estrogen-progesterone regimen could relieve pain from endometriosis as effectively as GnRH-a alone and reduce hypoestrogenic symptoms and bone loss.Therefore,it is a safe and effective treatment.

ObjectiveTo investigate the correlation between electro-acupunctured point Houxi(SI3)and activated brain function areas, contrast the images produced with electroacupuncture at left and right points Houxi and make a comparison with electroacupuncture at point Hegu(LI4)in patients with peripheral facial paralysis.MethodPatients with peripheral facial paralysis, six on the left side and six on the right side, were enrolled as subjects. A scan of the whole brain was taken using fMRI during electroacupuncture stimulation. The images were processed using SPM software. An analysis using at-test (P<0.01) showed differences in brain functional images produced with electroacupuncture at different points.ResultElectroacupuncture at left point Houxi increased the signals of brain regions: rightcaudate nucleus, right cingulate gyrus, right parahippocampal gyrus, right superior temporal gyrus, the brainstem and the cerebellar vermis. Electroacupuncture at right point Houxi increased the signals of brain regions: right medial frontal gyrus, left middle frontal gyrus, left anterior cingulate gyrus, rightcingulate gyrus and right superior temporal gyrus.ConclusionThere is a difference in the image between electroacupuncture at point Houxi and at point Hegu or Dicang(ST4). There is also a larger difference in the image between bilateral points Houxi. The brain regions with high-frequency or low-frequency signals are not consistent. The results further prove the scientificalness of “Point Hegu is indicated for diseasesin the face and mouth” and also show that the cognominal acupoints on the two sides ofthe human body may have some differences, e.g. the conduction pathways are not completely the same and the therapeutic effects are not completely consistent.

Objective To observe the effects of vitamin C (VC) and E (VE) on the uhrastrueture of liver, kidney and brain tissue of fluorosis rats. Methods One hundred and twenty Wistar rats were chosen as the experimental animals and were divided into 9 groups randomly. The control group were given distilled water and the fluoride exposed group were given distilled water containing sodium fluoride 150 mg/L. The throe VC-fluoride exposed groups were given VC orally in a dose of 50,100,150 mg·kg-1.d-1, respectively, and the three VE-fluoride exposed groups were given VE of 25,50,75 mg·kg-1·d-1, respectively. The VC-VE-fluoride exposed group were given VC of 100 mg·kg-1·d-1and VE of 50 mg·kg-1·d-1at the same time of high fluoride water intake. The rats were sacrificed after 9 months and the ultrastructure changes on liver, kidney and brain tissues of each group were observed under transmission electron microscope(TEM). Results The uhrastrueture of liver, kidney and brain showed pathologic changes in the rats that drank water containing high eoneentrations of sodium fluoride. ①Edema of hepatocytes, smeared mitochontria and nuclear matrix, lipid droplet in eytoplasm of hepatocytes, margination of nueleohs as well as obvious swelling of liver sinusoidal endothelial were observed in fluoride exposed group. ② There were marginafion of heterochromatin, expansion of cell space and endoplasmic reticulum in the kidney after the exposure to excess fluoride.③Signifieant changes were found on glial eells on the brain, including cell swelling, increase and marginafion of heterochromatin in the fluoride exposure group. There were no significant uhrastrueture changes in the VC or VE intervention group, while the VC-VE-fluoride exposure group was almost the same as the control group. Conclusions Fluoresis may cause damage on liver, kidney and brain in rats. VC and VE, alone or combined, have protective effects, and the combined supplementation was stronger than single supplementations.

Objective To evaluate the expression of Toll-like receptor(TLR)on the monocyte- derived dendritic cells(DC)from chronic hepatitis B(CHB)patients and to analyze the expression pro- file and significance of the TLR such as TLR3,TLR4,TLR?,TLR8 and TLRg,which are associat- ed with immune response to viral infection.Methods Peripheral blood mononuclear cell(PBMC) centrifugated by the hydroxyethyl starch(HES)centrifugation were cultured and induced into DC by granulocyte-maerophage colony stimulating factor(GM-CSF)and interleukin-4(IL-4),and their mor- phology and phenotype were detected by the inverted microscope and flow cytometry respectively. Monocyte-derived DC were obtained from 10 chronically hepatitis B virus(HBV)-infected patients and 15 healthy volunteers.TLR3,TLR4,TLR7,TLRS,TLR9 expression on immature and mature DC were analyzed by FACS Calibur.DC was pulsed with HBcAg on day 3 and 5,then DC maturation and ability to process HBcAg and to stimulate autogeneic T cells were evaluated.Results Monocyte- derived DC developed different TLR expression patterns as they went through different maturation stages.TLR7,TLR8 expressions on immature DC and TLR3,TLR7 expressions on mature DC were lower in CHB than in control(for TLR7,TLR8 expression on immature DC:75.9%,1.0%vs 98.4%,15.4%,P

OBJECTIVETo observe the effect of Wenyang Huazhuo Tongluo Recipe (WYHZTLR) on the proportion of T helper 17 cells (Thl7)/regulatory T cells (Treg), and serum levels of IL-17 and IL-10 in peripheral blood of systemic sclerosis (SSc) patients with yang qi insufficiency and turbidity induced collaterals blockage syndrome (YQITICBS).

METHODSTotally 82 SSc patients were randomly assigned to the Western medicine group (as the control group) and the integrated Chinese and Western medicine group (as the treatment group), 41 cases in each group. All patients took methotrexate (MTX) tablet and prednisone tablet. Patients in the treatment group additionally took WYHZTLR. The treatment course for all was six consecutive months. Besides, another 70 healthy volunteers were recruited as a healthy control group (as the healthy group). Percentages of Th17 and Treg in peripheral blood were detected by flow cytometry. Serum levels of IL-17, IL-10, von Willebrand factor (vWF), aminoterminal propeptide of type l procollagen (PIIINP), and cross-linked carboxyterminal telopeptide of type I collagen ( I CTP) were measured by double antibody sandwich ELISA. The correlations between Th17/Treg and levels of vWF, PIIINP, I CTP, skin score, and disease activity index were observed by Pearson correlation analysis.

RESULTSThe percentage of Th17 in peripheral blood, ratios of Th17/Treg, and the serum level of IL-17 were significantly higher, but the percentage of Treg and the serum level of IL-10 were significantly lower in SSc patients, when compared with those of the healthy group (P <0. 05, P <0. 01). Compared with the same group before treatment, the percentage of Thl7, ratios of Thl7/Treg, and levels of IL-17, vWF, and PIIINP all decreased in the two groups after treatment (P <0.05, P <0.01), but the percentage of Treg and the IL-10 level increased (P <0. 05, P <0. 01). Meanwhile,the level of I CTP was higher in the treatment group after treatment (P <0. 05). The improvement of all indices except the percentage of Th17 was more obvious in the treatment group than in the control group (P <0. 05, P <0. 01). The ratio of Th17/Treg was positively correlated with levels of vWF, PIIINP, skin score, and disease activity index before and after treatment respectively (P <0. 01), but with no obvious correlation with the level of I CTP (P >0. 05).

CONCLUSIONWYHZTLR could achieve its therapeutic effect on SSc patients by regulating Th17/Treg imbalance, lowering levels of vWF and PIIINP, and elevating the level of I CTP.

The effectiveness and safety of acupuncture-moxibustion for the treatment of agrypnia was systematically reviewed. The clinical randomized controlled trial (RCT) of acupuncture-moxibustion for agrypnia were collected. The literature and document on acupuncture-moxibustion RCT for the treatment of agrypnia that published from January of 2001 to March of 2012 was searched with computer in PubMed, CNKI, Wanfang and VIP database. According to Cochrane Handbook 5. 1. 0, the bias risk and quality assessment were performed on every included trial and RevMan 5. 0 software was applied to make the Meta analysis. Totally 14 researches were included, involving 2662 cases. The Meta analysis showed that the differences of total effective rate between acupuncture-moxibustion and clinical routine treatment were significant [RR = 1.16, 95% CI (1.12, 1.19), Z = 9.32, P < 0.000 01]. The results indicate that total effective rate of acupuncture-moxibustion for agrypnia is obviously superior to that of clinical routine treatment, meaning clinical efficacy of acupuncture-moxibustion is served credit.

Secondary metabolites are the result of that plant interaction with biological and non-biological factors in the long-term evolution process, and play an important role in plant growth, development and physiology. The effective components of medicinal plant are usually the secondary metabolites in plant cells, and the synthesis of them are affected by a variety of factors, such as environmental impact. Acquirement of the secondary metabolites via callus culture has the advantage of low cost and less environmental impact. The synthesis and accumulation of medicinal plant secondary metabolites are not only controlled by light, temperature and pH, but also infected by germplasm, plant growth regulator and elicitor. This article presents a review of the influencing factors, and provides a basis for further study and development.
