Objective To study the effect of the cord blood stem cell transplantation therapy in patients with severe hepatitis. Methods Forty patients with severe hepatitis were randomly divided into control groups (n=20) and observed group (n=20). The patients in two groups were treated with the conventional liver protective therapy respectively, such as compound glycyrrhizin and glutathione. The patients in observed groups were performed with the cord blood stem cell trans-plantation therapy. After isolation and purification, the cells were transplanted into the liver via hepatic artery and then were transplanted via peripheral veins. The biochemical indices of albumin (ALB), prothrombin activity (PTA),alpha-fetoprotein (AFP)and clinical symptoms were detected at different times after therapy. Results After 4-week therapy, the levels of PTA (%)and AFP(μg/L)were significantly increased in observed group compared with those of control group (53.56 ± 5.15 vs 48.26±5.53,92.16±9.09 vs 43.57±11.33,P＜0.01). After 8-week therapy, the levels of alanine aminotransferase (ALT), total bilirubin (TBIL) and AFP were significantly decreased in observed group than those of control group. The level of PTA was sig-nificantly higher in observed group than that of control group (62.61±4.35 vs 54.95±3.01,P＜0.05 or P＜0.01). There were no significant differences in levels of ALB and blood ammonia between two groups (P>0.05). There were no serious complications and adverse reactions in two groups of patients. There was no significant difference in mortality between two groups ( 20%vs 35%,χ2=0.818,P>0.05). Conclusion Cord blood stem cell therapy has a good effect on treating severe hepatitis, which is safe and no significant adverse reactions, and can be used as a new method for treating the severe hepatitis.

OBJECTIVE:To reduce the types of drugs which was not consistent with the accounts in monthly checking of out-patient department,reduce the wastage of dismounted drugs and improve dismounted drug management. METHODS:Through qual-ity control circle(QCC),analyzing the reasons for inconformity of accounts and drugs,adopting relevant countermeasures of staff training,cipher prescription,counter storage,managed by designated person,expiry data management and so on,the process of dismounted drug management was formulated and implemented. The types of drugs which was not consistent with the accounts and activity growth value of circle members were analyzed statistically before,during and after QCC. RESULTS:The types of drugs which was not consistent with the accounts were 33.6,21.2 and 13.6 before,during and after QCC,decreasing by 59.5%. The ac-tivity growth value of circle members were all positive value. CONCLUSIONS:QCC of outpatient pharmacy can effectively reduce the types of drugs which is not consistent with the accounts in monthly checking,standardize dismounted drug management and im-prove pharmaceutical care quality.

OBJECTIVE:To observe therapeutic efficacy of Rhodiola wallichiana injection for swelling and pain in fracture pa-tients during perioperative period. METHODS:120 patients with closed fresh extremity long bones fracture were randomly divided into trial group and control group,with 60 cases in each group. Both groups received open reduction and plate fixation. Before and after op-eration,control group was given routine medicine and anti-inflammatory treatment;trial group was additionally given R. wallichiana in-jection 10 ml(250 ml added into 5%Glucose injection)intravenously,qd,on the basis of control group. A treatment course lasted for 10 d. The swelling degree before operation,1 d and 3 d after operation,pain degree on the day of operation and 1,2,3 and 7 d after operation,complication and average length of stay were observed and compared between 2 groups. RESULTS:The extent of swelling and pain,the incidence of complications and average hospitalization days of trial group were lower or shorter than control group,with statistical significance (P<0.05). CONCLUSIONS:R. wallichiana injection can promote blood circulation and remove blood stasis, ease the hydropsia and pain,relieve swelling and pain,reduce the incidence of complications and shorten hospitalization day.

Objective To investigate the incubation period, degree of injury, distribition of pathological changes, and therapeutic effect of eye injury in “8?4” mustard gas poisoning accident. Methods The relationships among contact pattern, contact time and incubation period and degree of injury were analyzed, and the distribition of pathological changes and therapeutic effect were assessed. Results An incubation period was found in eye injury after the exposure to mustard gas. It varied with the mode of contact and the time of exposure to the gas. The conjunctiva was the main site of injury, follwed by the eyelid, and then the cornea and the iris. Conclusions The length of the incubation period varied with the degree of injury and contact time and mode. Thorough washout and medicinal intervention should be instituted as early as possible.

Objective To explore the apoptosis of K562/G01 cells induced by triptolide through MDM2/p53 signaling pathway. Methods K562/G01 cell line was treated with different concentrations of triptolide. MTT was used to detect the cell proliferation inhibition rate. FCM was used to determine the apoptosis rate changes in 12 h and 24 h. The mRNA expression levels of bcr-abl, XIAP, MDM2, p53 were detected by real-time quantitative PCR. Results After treatment by 10, 20, 40, 80, 100 nmol/L TP in 12, 24, 48 h, the viability of K562/G01 cells was inhibited in time-dose dependence manner. K562/G01 cells was treated by 20 nmol/L, 40 nmol/L TP after 12 h, 24 h, the cell apoptosis rate was rising with drug concentration and time. The bcr-abl, XIAP, MDM2 mRNA expression was down-regulated and p53 mRNA expression was up-regulated by TP. Conclusion TP can inhibit the growth of K562/G01 cell line and induce apoptosis through XIAP-MDM2-p53 signaling pathway.

Objective To study the effect of allicin on the growth and radiosensitivity of human pancreatic carcinoma BXPC3 cells.Methods BXPC3 cells were exposed to X-rays in the presence or absence of allicin.Cell proliferation was measured by MTT assay.Cell cycle distribution and apoptosis were detected by flow cytometry assay.Cell radiosensitivity and the influence of allicin on it was evaluated by colony formation assay.The expressions of Bax and Bcl-2 proteins were assayed by RT-PCR and Western blot.Results IC50 values of allicin on cell growth were 76.24,58.34 and 43.58 μmol/L under 12,24 and 48 h treatment,respectively.Treatment of cells with allicin obviously inhibited cell growth after irradiation and hence increased radiosensitivity (t =2.74,P ＜ 0.05).This treament also enhanced radiation-induced cell cycle arrest at G2/M phase (t =11.41,P ＜0.05),apoptosis induction (t =12.36,P ＜ 0.05),and Bax expression (t =4.83,P ＜ 0.05),but it decreased Bcl-2 expression (t =3.69,P ＜ 0.05).Conclusions Allicin could inhibit cell growth,induce cell cycle arrest and apoptosis via Bax/Bcl-2 pathway and hence increases radiosensitivity of BXPC3 cells.

This study was aimed to investigate renal protective effects and mechanism of Gui-Zhi(GZ) decoction in hyperuricemic mice.Potassium oxonate was used to induce hyperuricemia mouse model.Mice were randomly divided into 6 groups,which were the blank control group,model group,allopurinol group (5 mg·kg-1) and GZ decoction group (900,1 799 and 3 598 mg·kg-1).Hematoxylin eosin staining was used to observe the histopathological changes of renal tissues in mice.Commercial assay kits were used to measure levels of uric acid (UA),creatinine (Cr) and blood urea nitrogen (BUN) in serum and urine,as well as the xanthine oxidase (XOD) activity in liver.Renal protein levels of urate transporter 1 (URAT1),glucose transporter 9 (GLUT9),ATP-binding cassette G member 2 (ABCG2),organic cation transporter 1 (OCT1),OCT2,organic cation/carnitine transporter 1 (OCTN1) and OCTN2 were detected by western blot.The results showed that compared with the model group,GZ decoction can obviously decrease serum levels of UA,Cr and BUN,increase urine levels of UA and Cr,resulting in the elevation of fractional excretion of UA in hyperuricemic mice.Additionally,GZ decoction obviously inhibited hepatic XOD activity in hyperuricemic mice.Furthermore,GZ decoction downregulated renal URAT1 and GLUT9 protein levels,upregulated renal ABCG2,as well as OCT1,OCT2,OCTN1 and OCTN2 protein levels in hyperuricemic mice.It was concluded that GZ decoction had hypouricemic and renal protective effects in hyperuricemic mice,which might be associated with the reduction of UA production via inhibiting hepatic XOD activity,promoting UA and other organic ion excretion via regulating renal organic ion transporter protein levels.
