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.

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.

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.

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.

Objective To investigate the effects of 17-methoxyl-7-hydroxy-benzene-furabcgakcone( MHBFC ) on isoproterenol-induced ventricular remodeling in mice. Methods Isoproterenol(ISO)was given subcutaneously(1 mg·kg-1, twice per day for 7 d)to induce ventricular remodeling in mice. Mice were divided into normal control group,model group, captopril group,MHBFC low and high-dose groups. 65 mg·kg-1 captopril was given by intragastric administration in captopril group,2. 5,5. 0 mg·kg-1 MHBFC were given by intravenous injection in MHBFC low and high-dose groups. At the end of the 7th day,the hearts of the mice were weighted,and myocardial hypertrophy index was expressed as heart weight/body weight, double kidneys weight/body weight and lung weight/body weight( HW/BW,KW/BW and LW/BW). Colorimetric method was used to determine the content of hydroxyproline( Hyp)in heart,the activity of superoxide dismutase( SOD)and the content of malondialdehyde( MDA)in serum. The histological changes were observed by HE and Masson’s staining,the changes of cross section area( CSA),collagen volume fraction,( CVF)and perivascular circumferential collagen area( PVCA)were determined. Results Compared with the model group,MHBFC potently inhibited cardiomyocyte hypertrophy,decreased the HW/BW, KW/BW and LW/BW,improved cardiac pathology changed,increased the of activity SOD,decreased the content of MDA in serum and the content of Hyp in heart tissue(P﹤0. 01 or P﹤0. 05),decreased the CVF and PVCA(P﹤0. 01). Conclusion MHBFC possesses protective effects against ISO-induced ventricular remodeling in mice,which may be related to its actions in reducing the oxidative stress and improving the antioxidant activity of the body.
