OBJECTIVE:To study the compatible stability of Ceftriaxone Sodium with Compound Sodium Chloride Injection or Sodium Lactate Ringer's Injection and study the compatible stability of the simulated in vivo peak concentration of ceftriaxone sodium with instant high concentration of calcium gluconate ion injection. METHODS: The concentration of Ceftriaxone Sodium in the mixture was determined by HPLC,meanwhile,the changes of the mixture in appearance,pH value,and the insoluble particles at room temperature were observed. RESULTS: At 0～2 hours,the mixture of Ceftriaxone Sodium and Compound Sodium Chloride Injection was clear in appearance;however,at 2 hours,it was white cloudy macroscopically,and its pH valued increased,ceftriaxone sodium content decreased and insoluble particles increased. The ceftriaxone sodium content reduced when mixed with sodium lactate ringer's injection. After mixing of simulated in vivo peak concentration of ceftriaxone sodium with instant high concentration of calcium gluconate ion injection,the appearance of the mixture was stable but the concentration of Ceftriaxone Sodium reduced slightly. CONCLUSION: Ceftriaxone Sodium can't be used in combination with Compound Sodium Chloride Injection or Sodium Lactate Ringer's Injection. Whether it is suitable to infuse calcium gluconate when ceftriaxone sodium (iv gtt) reached peak concentration remains to be confirmed in future study.

Objective To investigate the efficacy and influence factors of hysteroscopic guiding endometrial resection on dysfunctional uterine bleeding.Methods One hundred and eighty women with dysfunctional uterine bleeding were selected as our subjects in Maternal and Child Health Hospital of Qinhuangdao from Jan.2009 to Jan.2011.One hundred and fifty which meet with operation indications underwent hysteroscopic guiding endometrial resection.Operation periods,blood loss,adverse effects rate were recorded.Serum follicle stimulating hormone (FSH),luteinizing hormone (LH),estradiol (E2) and progesterone (P) hormone levels were detected at preoperative and postoperative.The efficacy was recorded at 6 and 12 months after the procedure.Results The average operation time and amount of bleeding were (31.2 ± 11.0)min and (32.3 ± 10.5) ml,and no blood transfusion performed during the operation.All cases got the succeed operation.There were no significant difference in terms of serum FSH,LH,E2 and P concentrations before and after treatment(P ＞0.05).At 6 months after treatment,improvement rate was 64.0％ (96/150),and effective rate was 32.0％ (48/150).The total effective rate was 96.0％ (144/150).At 12 months after treatment,the improvement rate was 58.0％ (87/150),effective rate was 36.0％ (54/150).The total effective rate was 94.0％(141/150).There was significant different in terms of total effective rate between 6 months and 12 months after treatment(x2 =113.6,P ＞ 0.05).Postoperative complications occurred in 2 cases,including 1 cases of abdominal pain,and 1 cases of dysmenorrhea.Uterine cavity depth,age and disease duration were the main factors affect the clinical efficacy.(OR(95 ％ CI):-1.14 (-1.17 to-1.07),1.60 (1.31 to 2.08),-1.02(-1.14 to-1.08),P ＜ 0.05).Conclusion Treatment of hysteroscopic guiding endometrial resection on dysfunctional uterine bleeding is proved to be efficacy due to the less adverse reaction.

Objective To discuss the expression and clinical significance of vascular endothelial growth factor (VEGF)-C and nm23-H1 in colorectal carcinoma.Methods Immunohistochemical staining was employed to determine the expression of VEGF-C and nm23-H1 in the carcinoma tissues of 120 cases with colorectal carcinoma and in the adjacent mucosal tissues of 55 cases as control,and analyzed their correlation with cliniopathological features and prognosis.Results The positive expression of VEGF-C in the carcinoma tissues was 71.7％ (86/120),significantly higher than that in the adjacent mucosal tissues [21.8 ％ (12/55)],and there was significant difference (x2 =35.186,P ＜ 0.01).The positive expression of nm23-H1 in the carcinoma tissues was 57.5％ (69/120),significantly lower than that in the adjacent mucosal tissues [90.9％ (50/55)],and there was significant difference (x2 =18.351,P ＜ 0.01).The expression of VEGF-C was significantly correlated with lymph node metastasis (P ＜ 0.05),and the expression of nm23-H 1was significantly correlated with lymph node metastasis and pathological type (P ＜0.01 or ＜0.05).The expression of VEGF-C and nm23-H1 did not show a significant correlation with gender,age,tumor size,tumor site and depth of invasion (P ＞ 0.05).Spearman correlation analysis showed that the expression of VEGF-C was negatively correlated with the expression of nm23-H 1 in colorectal carcinoma (r =-0.472,P ＜0.01).Conclusions The joint detection of VEGF-C and nm23-H1 expression is very promising in prediction of the prognosis of patients with colorectal carcinoma.However,whether it can be used as a marker in prognosis judgment need further investigation.

Objective To observe the effects of permanent magnetic fields with different magnetic inductions on oxidative damage to human brain microvascular endothelial cells (HBMECs) under normal and hypoxic conditions. Methods HBMECs were cultured in vitro under normal and hypoxic conditions,then divided into a control group and groups receiving magnetic induction at 8.1,16.5,20.3,26.0,27.3,62.5,110.7 and 215.6 mT.Changes in superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in each group were measured 72 h after exposure to the magnetic fields. Results Under normal conditions the SOD activities of the magnetic groups were not significantly different from that of the control group. Only the MDA content of the 215.6 mT group was statistically different (slightly higher) than that of the control group (P ＜ 0.05 ).Under hypoxic conditions,there was again no statistically significant difference in SOD activity,but the MDA content of the 110.7 mT group was significantly lower. Conclusions Under normal conditions,a 215.6 mT permanent magnetic field has an effect on MDA in HBMECs; under hypoxic conditions a 110.7 mT permanent magnetic field has such an effect.

OBJECTIVE: To study the role of nuclear factor-kappa B (NF-kappaB) and cycloxygenase-2 (COX-2) in the onset of phlegm obstruction due to lung-deficiency in rats and the therapeutic mechanism of Huatan Recipe. METHODS: Twenty-four SD rats were randomly divided into normal group, model group and treatment group, with 8 rats in each group. The rats in the model group and treatment group were exposed to sulfur dioxide and cold wind to establish the rat model of phlegm obstruction due to lung-deficiency, and the rats in the treatment group were also treated with Huatan Recipe, a compound traditional Chinese medicine. The expression of NF-kappaB in the bronchial epithelial cells of the rats was tested with the method of immunohistochemistry, and the COX-2 mRNA in the lung tissues of the rats was measured by using reverse transcription-polymerase chain reaction. RESULTS: The expressions of NF-kappaB and COX-2 mRNA in rats of the model group were higher than those of the normal group (P<0.01), and the expressions of NF-kappaB and COX-2 mRNA in rats of the treatment group were obviously lower than those of the model group (P<0.01). CONCLUSION: The NF-kappaB and COX-2 play an important role in the onset of phlegm obstruction in rats. Huatan Recipe may prevent the development of phlegm obstruction by down-regulating the expressions of NF-kappaB and COX-2 mRNA.
