Measuring the content of soluble reducing sugar, total sugar, soluble protein, guanosine, alkaloids, and succinic acid of Pinellia ternata tuber were measured by anthrone-sulfuric acid colorimetric method, Coomassie brilliant blue method, RP-HPLC, reverse potentiometric titration, acid dye colorimetry, respectively. The result showed that yellow light could promote the growth and development of P. ternata and increase the content of soluble reducing sugar, total sugar, alkaloids, and succinic acid. Under blue light could promote the content of soluble protein and guanosine. Red and yellow light increased the content of chlorophyll a and chlorophyll b, contrastively blue light reduced the content of chlorophyll a and chlorophyll b. White film through the most uniform spectrum was most conducive to the synthesis of chlorophyll a. As single film, blue film, yellow film were more conducive to the synthesis of chlorophyll a, green film and red film had been relatively beneficial to the synthesis of chlorophyll b. Bulbil formed the largest number and the biggest propagation coefficient of P. ternata under red light showed that it could increase the production of P. ternata under red light.

Objective To investigate the association of angiotensinogen(AGT)gene A-6G、T174M and G-217A polymorphisms with the risk of essential hypertension(EH)in the elderly of Han nationality.Methods Genotypes of AGT gene A-6G,T174M and G-217A polymorphisms in 177 aged EH patients and 86 sex and age-matched controls were analyzed with gene chip technology.Results The A-6G and T174M polymorphisms of AGT gene were significantly associated with EH.The numbers of the three genotypes of A-6G were 113,58 and 6 in the patient group and 70,15 and 1 in the control group(P= 0.014)and those of T174M were 94,77 and 6,60,25 and 1(P=0.031),respectively.G-217A polymorphism was not related to EH.Individuals carrying A-6G AA and T174M CC genotypes showed 57% and 56% lower risk of EH(OR=0.43;95%CI=0.23-0.82 and OR=0.44;95%CI=0.25-0.79, respectively).Conclusions The A-6G AA and the T174M CC genotype may be related with decreased risk of EH and G-217A polymorphism may have little role in the etiology of EH in Han nationality.

OBJECTIVETo explore the feasibility of human leucocyte antigen (HLA) haploidentical related T-cell undepleted allogeneic bone marrow transplantation (Allo-BMT) combined with Chinese medicine for the treatment of leukaemia.

METHODSFour patients with chronic myeloblastic leukemia (CML) and 4 with acute myeloid leukemia (AML) received allo-BMT with graft from 1 - 3 HLA-mismatched related donors. All patients were pre-treated with standardized conditioning regimen consisting of high dose Ara-c, cyclophosphamide (CY) and total body irradiation (TBI) or busulfan. Donors were given G-CSF 250 microg/d for 7 days prior to marrow harvest. To prevent GVHD, besides application of CSA and MTX, ATG 2.5 mg/kg was given everyday for 4 days before transplantation, and MMF 1.0 g per day starting from the 7th day after transplantation. Chinese medicine for replenishing qi and yin and strengthening Pi and Wei was administrated orally after transplantation.

RESULTSSuccessful haematopoietic reconstruction was seen in all patients. The median days for reaching of granulocyte >0.5 X 10(9)/L and platelet > 20 x 10(9)/L were 12 (range 10-14) and 20 (range 18-25) days respectively. GVHD of skin in various grade was seen in 7 patients, among whom only one advanced to grade IV; besides, 2 accompanied with GVHD of gut, one with hemorrhagic cystitis, one died for concurrent infection on the 81st day, and one left hospital of his own accord on the 46th day. The median follow-up duration was 18 (range 2-32) months, during this period six patients were alive in a disease-free situation.

CONCLUSIONCombined therapy of HLA haploidentical related T-cell undepleted Allo-BMT and Chinese medicine plus immunosuppressants with pre-harvest G-CSF application in doner could effectively reduce the incidence of acute severe GVHD and raise the disease-free survival rate in treating leukaemia.

Objective To evaluate carotid intima-media thickness(IMT) and elasticity in patients with pregnancy-induced hypertension(PIH) using ultrasound radio-frequency data(RF-data) technology.Methods Twenty-seven PIH women(mean brachial blood pressure:108 mm Hg,1 mm Hg=0.133 kPa)were included and thirty age- and gestational week-matched normal pregnant women served as controls.Carotid IMT and stiffness were evaluated using quality IMT(QIMT) and quantitative artery stiffness(QAS)techniques with color Doppler.Results Carotid IMT and elasticity parameters,including pulse wave velocity,pressure at T1,arterial augmented pressure(AP) and arterial augmented pressure index(AIx) were significantly higher in PIH group than in the normal group[IMT:(466.84±118.50)μm vs (386.58±125.79)μm;PWV:(7.09±1.97)m/s vs (5.95±1.11) m/s;PT1:(127.50±14.29) mm Hg vs (105.89±11.02)mm Hg;AP:(5.14±3.39) mm Hg vs (1.98±2.19)mm Hg;AIx:(7.58±8.73)% vs (-4.79±7.92)%)], and there were significant differences(t=2.660,2.660,3.460,3.460,3.460,all P＜0.01).Conclusions PIH women have significantly increased carotid IMT and decreased elasticity compared with normal pregnant women.Radio-frequency technique could reliably reflect the changes of the carotid arterial structure and elasticity in patients with pregnancy-induced hypertension.

AIM: To investigate the expression of EMMPRIN, MMP1, MMP9 and TIMP2 in retinoblastoma (RB) and normal retinal tissues and their clinicopathological significance and interrelationship.METHODS: Envision immunohistochemistry stainings of EMMPRIN, MMP1, MMP9 and TIMP2 were performed in 30 enucleated eyeballs with retinoblastoma and 15 specimens of normal retina tissue, which had been routinely imbedded with paraffin.RESULTS: Positive rate of EMMPRIN, MMP1, MMP9 expression was higher in RB tissue than in normal control (P<0.01), while TIMP2 expression was lower in RB than in normal retinal tissue (P<0.01). Samples from RB cases of clinical stage Ⅰ, differentiated type, and life span≥2 years had lower positive rate in expression of EMMPRIN, MMP1, MMP9 than those from RB cases of clinical stage Ⅲ, undifferentiated type, and life span<2 years (P<0.05 or P<0.01), while samples from RB cases of differentiated type, optic nerve unaffected, and life span≥2 years had markedly higher positive rate in expression of TIMP2 than those from RB cases of undifferentiated type, optic nerve involved and life span<2 years (P<0.05 or P<0.01). In RB tissues, EMMPRIN, MMP1, MMP9 expressions were highly consistent (P<0.05), whereas TIMP2 expression is highly inconsistent with EMMPRIN, MMP1, MMP9 expression levels (P<0.05).CONCLUSION: The expression level of EMMPRIN, MMP1, MMP9 and TIMP2 may be an important marker of RB progression, invasion and prognosis. There exist internally mutual regulation relations among them.
