Allotransplantation with fetus parathyroids was performed in 4 cases of hypoparathyroidism after the grafts had been radiated with 6 Gy of 60Co and cultured in Balb/c nude rats for 14 davs.The recipients took 4 days of cyclosporine A(dose of 20～25mg·kg-1/d),one day preoperation and 3 days postoperation.The patients were followed up for 5～60 months.Traced observation on the patients'clinical symptoms and signs,the changes in the doses of Calcium and Vitamine D and in the levels of serum Calcium and parathyroid hormone was conducted to determine the grafts'survival.The results were satisfactory with all cases surviving for the follow-up period.It is considered that this method is much better than any we did previously.

Aim To observe the protective effects of two flavone morphons on hypoxia/reoxygenation(H/R) injury in myocardial cells and explore the mechanisms.Methods The hypoxia/reoxygenation injury model of cultured neonatal rat cardiomyocytes was developed. The cell morphology,the spontaneous beating,the survival rate,the content of LDH,NOS,T-SOD,MDA and the activity of Na+,K+-ATP,Ca2+,Mg2+-ATP enzyme were determined in the cultured neonatal rat cardiomyocytes injuried by H/R.Results Compared with the model,preconditioning by two flavone morphons enhanced the spontaneous beating and the survival rate. Meanwhile,it increased the activity of T-SOD,Na+,K+-ATP,Ca2+,Mg2+-ATP enzyme and decreased the release of LDH,NOS,MDA(P

AIM To observe the clinical efficacy of Huazhi Rougan Granules (Artemisiae scopariae Herba,Cassiae Semen,Rhei Radix et Rhizoma,etc.) in the treatment of damp-heat accumulation type non-alcoholic steatohepatitis (NASH) and its influence on insulin resistance.METHODS During January 2014-January 2016,a total of one hundred and twenty patients with damp-heat accumulation type NASH,given diet and exercise guidance,were randomly and equally divided into control group (polyene phosphatidylcholine) and treatment group (Huazhi Rougan Granules),administrated for twelve weeks.The levels of serum alanine aminotransferase (ALT),aspartate aminotranferase (AST),gamma-glutamyltransferase (GGT),total cholesterol (TC),triglyceride (TG),γ-glutamyl transpeptadase (GGT),fasting plasma glucose (FPG),fasting insulin (FINS),HOMA-IR index,adiponectin (ADPN) and leptin,body mass index (BMI) and uhrasound examination were detected before and after the treatment,respectively.These data were compared in two groups.RESULTS Compared with the control group,the serum ALT,AST,GGT,TC,TG,FPG,FINS and HOMA-IR of the patients in the treatment group decreased significantly,and liver fat were effectively reduced,while serum adiponectin increased markedly (P ＜ 0.05).After the treatment,remarkable reductions in the levels of BMI,leptin were observed in both groups (P ＜ 0.05).CONCLUSION Huazhi Rougan Granules combined with lifestyle modulation can effectively improve the syndrome of damp-heat accumulation type NASH by lowing insulin resistance.

Objective To investigate the neurological and cerebrospinal fluid interleukin-6 effects of butylphthalide on brain hemorrhage.Methods Ninety cerebral hemorrhage patients in principle based on a random draw were equally divided into the treatment group (45 cases) and the control group (45 cases).Two groups were given basic treatment, the control group were treated with nimodipine tablets adjuvant therapy, the treatment group were treated with butylphthalide soft capsules adjuvant therapy, all patients were treated for 30 days.Results After treatment, the national institutes of health stroke scale (NIHSS) score was shown significant downward trend in the two groups((9.45±0.44) to (2.09±0.45) scores;(9.44±0.21) to (4.58±0.65) scores) and compared with pre-treatment differences were significant (t=16.983, P=0.000;t =8.112, P =0.000), and the NIHHS score in treatment group was significantly lower than in control group(P =0.000).The mini-mental state examination (MMSE) score and activities of daily living (ADL) scores were shown significant upward trend in the two groups,compared with pre-treatment differences were significant(P ＜0.05).MMSE score(26.98±3.91) and ADL scores(34.29±6.42) scores in the treatment group were significantly lower in the control group((23.09±5.33) scores, (30.28±5.33)scores) after treatment(t =6.498, P =0.000;t =8.123, P =0.000).After treatment, the values cerebrospinal fluid interleukin-6 (IL-6) expression in the two groups were significantly reduced (P ＜ 0.05), while the value of cerebrospinal fluid IL-6 expression in the treatment group were significantly lower than the control group ((45.38 ± 13.02) ng/L vs (122.87± 17.42) ng/L, t =18.334, P =0.000).The adverse reactions of the two groups were mild, and were significantly improved after symptomatic treatment.Conclusion Butylphthalide adjuvant treatment of cerebral hemorrhage can improve nerve function, cognitive function and activities of daily living, its safety is also better.It plays its role may related to effectively reduce the IL-6 expression.

Objective:To observe the protective effect of Yulangsan polysaccharide ( YLSP) on liver injury induced by cyclophos-phamide(CTX) in mice. Methods:Liver injury induced by CTX in mice was used as the animal model and the mice were randomly di-vided into the normal group, CTX model group, biphenyldicarboxylate ( BPDC) group, YLSP group respectively with high, medium and low dose. Except the normal group, the other groups were injected with CTX, i. p. , for 7 days to make the model. Then the ani-mals in the YLSP groups were intragastrically administered with YLSP for 7 days. The activities of alanine aminotransferase( ALT) , as-partate aminotransferase( AST) in serum, malondialdehyde( MDA) , superoxide dismutase( SOD) , glutathione( GSH) and glutathione peroxidase ( GSH-Px) in liver tissue were investigated. Hematoxylin and eosin ( HE) stain was used to study the changes in hepatic tissue of the pathological mice. Results:Compared with the model group, YLSP could obviously reduce the activities of ALT, AST and the content of MDA, and increase the content of GSH, SOD and GSH-Px (P<0. 05 or P<0. 01). HE staining showed that YLSP had significant protective effect on liver injury induced by CTX. Conclusion:YLSP has protective effect on liver injury induced by CTX.

BACKGROUND: Uncontrolled-rate freezing in -80 ℃ refrigerator is convenient, while controlled-rate freezing in -196 ℃ liquid nitrogen is reliable and long-term, the combination of the two can simplify the process and has been successfully used in clinics. OBJECTIVE: To explore the influences of different cryoprotectants by ladder-style freezing from -80 ℃ low temperature refrigerator to liquid nitrogen on the cryopreservation of hemopoietic stem cells. METHODS: The experiments were divided into four groups: 10% dimethyl sulfoxide (DMSO) group, 5% DMSO combined with 3% hydroxyethyl starch group, 5% DMSO combined with 0.25 mol/L trehalose group, 5% DMSO combined with 3% hydroxyethyl starch and 0.25 mol/L trehalose group. Peripheral hemopoietic stem cells were cryopreserved by ladder-style freezing from -80 ℃ low temperature refrigerator to liquid nitrogen. The ultrastructural changes were examined by transmission electron microscopy, the expressions of Annexin-V, PI and Caspase-3 were detected by flow cytometry. RESULTS AND CONCLUSION: There was no significant difference in survival rate, apoptotic rate and necrotic rates of the cryopreserved cells in the four groups (P > 0.05). The ultrastructural changes had no significant difference under the transmission electron microscopy. The viability was more than 90% in frozen-thawed mononuclear cell colonies, and the apoptosis was roughly 50% in the frozen-thawed CD45+ cell population, which contained many mature cells. Of hemopoietic stem cells, early stage cells have greater resistance to damage of cryopreservation than late stage cells. It is concluded that the addition of hydroxyethyl starch or trehalose into DMSO exhibits no synergistic protective effect on the cryopreservation of hemopoietic stem cells.
