Objective To observe the clinical effect of mannatide treatment with burn infection. Methods 100 burn patients admitted to Sichuan Nanchong Central Hospital from May 2009 to July 2012 were randomly divided into control group and treatment group, each group had 50 cases. Both of two groups were given conventional treatment, treatment group were treated with intravenous mannatide,control group were injected recombinant human growth hormone. Results The average length of stay in treatment group was signiifcantly shorter than control group (P=0.042). The clinical total effective rate, serum IgA, IgG, IgM and other indicators of immune function were improved signiifcantly compared with control group (P=0.037). There was no statistical signiifcance in blood protein, transferrin, prealbumin, glucose, insulin, urinary sodium, urinary potassium, chloride and other indicators of patients between two groups. Conclusion Mannatide can effectively enhance immune function, promote wound healing, shorter hospital stay and improve the clinical efifcacy.

OBJECTIVE:To provide reference for rational use of opioids analgesics. METHODS:1 882 prescriptions of opi-oids analgesics for cancer pain collected from our hospital in 2014 were analyzed by defined daily dose(DDD)and drug utilization index(DUI). RESULTS:The diseases of opioids analgesics prescriptions for cancer pain in our hospital in 2014 were mainly lung cancer,accounting for 42.19%. Commonly used opioids analgesics included Morphine sulfate sustained-release tablets,Oxycodone Hydrochloride sustained-release tablets and so on,and their DUI were all below 1.0. Top one drug in the list of amount and con-sumption sum was Morphine sulfate sustained-release tablets,and its main dosage form were tablets,injection and patches,in which tablets occupied the largest proportion,reaching 97.30%. CONCLUSIONS:The application of opioids analgesics for cancer pain in our hospital is basically rational in terms of drug types,dosage form and route of administration,but the dose of opioids an-algesics is small and their DUI is lower than 1;at the same time,there are a few irrational prescription.

Objective To investigate the efifcacy of thalidomide combined with VAD in treatment of elderly multiple myeloma(MM). Methods 76 cases of elderly MM were randomly divided into two groups, control group (n=38) were treated with VAD alone while the observation group (n=38) were treated with thalidomide and VAD. Clinical efifcacy and adverse reactions in two groups were compared. Results The total effective rate in observation group was 84.21%, which was signiifcantly higher than 55.26%in control group (P<0.05). After treatment, the M protein, myeloma cells andβ2-microglobulin in observation group were (20.77±4.15)×10-2μg/mL, (12.84±2.85)×10-2μg/mL and (2.48±0.53)μg/mL, which were signiifcantly lower than before treatment and control group(P<0.05). Hemoglobin in observation group was (108.83±5.81) g/L, which was signiifcantly higher than before treatment and control group(P<0.05). The adverse reactions were nausea, vomiting, drowsiness, constipation, infection and rash and so on in two groups after treatment, and there was no signiifcant difference between two groups. Conclusion Thalidomide combined with VAD regimen has a better effect in treatment of elderly multiple myeloma than single VAD, has less adverse reactions and well tolerated.

Objective To determine the efficacy of retrovirus-mediated HSV-TK gene transfer and GCV in a BALB/c mice model with urinary bladder transitional cell carcinoma. Methods A replication defective retroviral vector containing HSV-TK gene was used. In vivo experimental animals were divided into 3 groups.In group A,7 tumors were induced in BALB/c mice by subcutaneous injection of MBT-2 transitional cell carcinoma (TCC);the virus was directly injected into the tumor and the animals received intraperitoneal GCV.In group B, 6 tumors were induced in BALB/c mice by subcutaneous injection of transferred HSV-TK gene TCC and the animals received intraperitoneal GCV.In group C,6 tumors were induced in BALB/c mice by subcutaneous injection of MBT-2 TCC and the animals received intraperitoneal normal saline.Tumor-volume measurement was performed in these 3 groups 10 d and 20 d after treatment, and the volume changes were compared among the 3 groups. Results In vivo experiment indicated that the mean tumor volume of group A [MBT-2 group, (55.37?4.52) mm3] and group B [MBT-2/HSV-TK group,(49.77?4.15)mm3] was reduced significantly compared with that of group C [control group,(146.27?10.46)mm3](P0.05).At 20 d after treatment, the mean tumor volume of group A [(186.75?8.14)mm3] and group B [(72.50?6.70)mm3] was also reduced compared with that of group C [(441.76?41.80)mm3] (P

Objective To observe the in vitro influence of recombinant human B7-H4 protein on the cell proliferation cycle, apoptosis and cytokine secretion of peripheral blood activated T lymphocytes in cervical cancer patients.Methods After 48 h co-culture of peripheral blood T lymphocytes in 1 5 cases of cervical cancer with B7-H4 48 h,T lymphocytes′cell proliferation cycle, apoptosis and T lymphocytes subtypes changes were detected by FCM;the cytokines concentration in the culture supernatant was tested by ELISA array.Results After 48 h co-culture of peripheral blood T lymphocytes with B7-H4 48hs,G1,G2 and S phase of T cells accounted for 90.59%,8.55% and 0.87% respectively,which of the blank group were 92.83%,6.09% and 1.13% respec-tively;the Ki67 positive rates of CD4 + T and CD8 + T cells in the B7-H4 group were 2.13%±0.13% and 1.03%±1.33% respec-tively,which of the blank group were 2.74% ±0.98% and 1.71% ± 1.32% respectively;the proportion of CD4 + T and CD8 + T cells accounting for T cells in the B7-H4 group was decreased compared with the blank group,but the ratio of CD4 + T/CD8 + T and the proportion of CD4 + CD25 + Foxp3 + T cells were increased,in addition,the TGF-β1 secretion;concentration in the co-culture su-pernatant in the B7-H4 group was (259.25±32.78)pg/mL,which was higher than (202.75 ±20.1 7)pg/mL in the blank group. B7-H4 had no significant influence on the peripheral blood activated T cells apoptosis.Conclusion B7-H4 block the peripheral blood activated T cells at G2 phase,the S phase cells are obviously decreased;B7-H4 inhibits the cellular proliferation of CD4 + T and CD8 + cells,but may have the promoting effect on Foxp3 + T proliferation and TGF-β1 secretion;B7-H4 has no significant influ-ence on T cell apoptosis.B7-H4 plays a role in depressing anti-tumor T cell immune response of cervical cancer and may become a potential target of cervical cancer immunotherapy.
