Objective:To explore the effect of sodium cantharidate vitamin B6 injections in the adjuvant treatment of advanced cer-vical cancers. Methods:Totally 60 cases of advanced cervical cancer patients were randomly divided into the observation group and the control group, and the control group was given common DP chemotherapy and radiotherapy, while the observation group was given sodium cantharidate vitamin B6 injections additionally. After the 6-week treatment, the short-term curative effect, bone marrow inhibi-tion adverse reaction, immune function and life quality were compared between the two groups. Results:The short-term curative effect in the observation group was 66. 7%, which was significantly higher than that in the control group (40%)(P<0. 05). The degree of adverse reaction was significantly lower than that in the control group with statistical significance (P<0. 05). After the treatment, CD8 +, NK cells and CD8 + / CD4 + in the two groups were significantly improved, and those in the observation group were all better than those in the control group (P<0. 05). The improvement of life quality in the observation group was more notable than that in the control group with statistical significance (P <0.05). Conclusion: Sodium cantharidate vitamin B6 injections can significantly in-crease the short-term curative effect and immune function, decrease bone marrow inhibition and improve life quality of advanced cervi-cal cancer patients.

Objective To assess the effect of recombinant human leukemia inhibitory factor (rhLIF) on mouse embryo development in vitro Methods Mice were randomly divided to three groups, one in vivo control (group Ⅰ) and two in vitro (group Ⅱ and Ⅲ) Mice were sacrificed at 116 120 hours (group Ⅰ) and 44-48 hours (group Ⅱ and Ⅲ) subsequent human chorionic gonadotropin (hCG) injection Two cell embryos (group Ⅱ and Ⅲ) and blastocysts (group Ⅰ) were obtained Embryos in group Ⅱwere cocultured with human tubal fluid (HTF) + 10% human serum and in group Ⅲ with HTF + 10% human serum+rhLIF (1 000 U/ml) The number of embryo in different stage was recorded and compared Results Embryo in four, eight cell and morula was noted in group Ⅱ and Ⅲ, 87 7% versus 91 2% and 75 0% versus 85 4% respectively There was no significant difference. However, further embryo development to the blastocyst, expanded blastocyst, and hatching blastocyst in group Ⅱ (48 1%, 32 1% and 18 4%) was lower than that in group Ⅲ (82 3%, 59 7% and 36 3%) There was no difference between blastocyst in group Ⅰ and group Ⅲ (86 0% vs 82 3%). Conclusion RhLIF does not provide obvious stimulation in early mouse embryo, however, rhLIF can promote the growth, differentiation, and hatching of preimplantion blastocyst

Objective To investigate the features of resting energy expenditure (REE) in patients with well controlled type 2 diabetes mellitus (T2DM). Methods Totally 45 T2DM patients with stable blood glucose were enrolled. The general conditions, biochemical indicators, measurements of REE ( MREE), and basal energy expenditure (BEE) calculated with Harris-Benedict formula (HBEE) and Owen formula (OBEE) were recorded and compared. Results MREE had no significant difference with HBEE or OBEE in T2DM patients with stable blood glucose (P ＞ 0. 05). Correlation analysis showed that REE was significantly correlated with gender, age, body weight, body height, body surface area, and fat-free mass ( all P ＜ 0.05 ), but was not correlated with body mass index, fat mass, fasting plasma glucose, postprandial plasma glucose, haemoglobin Alc, total cholesterol, triglyceride, total protein, albumin, and haemoglobin (P ＞ 0. 05 ). Multiple regression analysis showed that fat free mass and age had the closest correlation with REE. Conclusions REE does not increase in T2DM patients with well controlled blood glucose. Factors that influence their REE are similar with healthy individuals. Determi nation of REE can provide useful information for the nutrition treatment of T2DM.
