Objective To investigate the effects of inositol hexaphosphate (IP6) on proliferation of human osteosarcoma cell line MG-63 and primary cultured osteoblasts so as to explore the optimal concentration for achieving anti-cancer effects.Methods We primary cultured and identified human osteoblasts.Then we made recovery and normal culture of human osteosarcoma cell line MG-63.We tested the proliferation of two kinds of cell lines under different concentrations of IP6 by MTT to determine the optimal concentration and then detected MG-63 cell cycle and apoptosis by flow cytometry.Results When IP6 concentration was more than 1 mmol/L,IP6 began to inhibit the proliferation of MG-63 cell line in the time-dose dependent manner.When the concentration reached 4 mmol/L,this inhibitory effect was the maximum.When IP6 concentration was 0.5 mmol/L or 1 mmol/L,the proliferation of osteoblasts was not obviously inhibited.When it was 2 mmol/L,the proliferation was slightly inhibited.A concentration of 4 mmol/L caused the apoptosis of osteoblasts.Conclusion IP6 can inhibit the proliferation of osteosarcoma cell line MG-63 and lead to its apoptosis.The optimal concentration is 2 mmol/L for achieving anti-cancer effects.

Objective The study was to evaluate DWI for quantifying liver fibrosis. Methods A total of 12 volunteers, 47 patients who had chronic HBV or HCV hepatitis and underwent liver biopsy [Scheuer score for fibrosis(S) and inflammation(G)] were enrolled in this study. They were scanned using a 1.5 T MR unit with b value of 0,250,500,750, 1000 s/mm~2. ADCs at b_(250-1000) and b_(500-1000) were the average ADCs of b=250, 500, 750, 1000 s/mm~2 and b=500, 750, 1000 s/mm~2. The studied the correlation between Scbeuer scores and ADC values, and conducted Mann-Whitney U test and Logistic regression to evaluate ADC for prediction of fibrosis scores. Results The average ADCs were (1.41± 0.11),(1.37±0.09), (1.27±0.05), (1.26±0.04), (1.22±0.06) mm~2/s respectively from SO to S4, stage at b=750 s/mm~2 (F=18.31, P<0.01). With the increase of fibrosis score, the average ADC decreased gradually, the two were better negatively correlated at b_(250-1000)(r=-0.727, P<0.01) than other b values. Using b_(750) and the two combined b values, the found significantly lower ADCs in S2 or greater versus S1 or less and in S3 or greater versus S2 or less fibrosis (P<0.01). The best predictor for S2 or greater was b_(750) with the largest AUC of 0.909, sensitivity of 85.7%, and specificity of 100.0% (ADC ≤1.35×10~(-3) mm~2/s). The best predictor for S3 or greater was b_(250-1000) with the largest AUC of 0.864, sensitivity of 69.6%, and specificity of 95.8% (ADC≤1.53×10~(-3) mm~2/s). Conclusion DWI can be a good predictor for scoring liver fibrosis for S2 or S3 stage above, while b_(750) and the combined b values are suitable for evaluation.

Objective To evaluate the effectiveness of preoperative perfusion chemotherapy via left gastric artery catheterization in patients with cardiac cancer of the stomach.Methods 56 operated cases with cardiac cancer,who had undergone preoperative perfusion chemotherapy via left gastric artery,were collected and analyzed.Results Most of the tumors were hypervascular as studied with DSA.After perfusion chemotherapy,there was amelioration of symptoms.Decrease in size about 50% of the tumor mass,shown in barium study were found in 32 patients,(18% of them).The survival rates one year,two years and three years after surgical resection were 98%,78.6% and 53.6% respectively.18 cases(32%)had gastric hemorrage,that was the main complication after perfusion.Conclusion Preoperative perfusion chemotherapy via left gastric artery in cases with cardiac cancer of the stomach is an effective measure in increasing resection rates in surgery.

OBJECTIVE:To investigate the characteristics of serious ADR in psychiatric hospital,and to provide reference for effective and safe use of drugs in the clinic. METHODS:114 cases of serious ADR in our hospital from 2004 to 2015 were ana-lyzed retrospectively in terms of general information,primary disease,route of administration,dosage form,drug types,organs or systems involved in ADR and clinical manifestations,top 5 ADR-inducing drugs and main clinical manifestations,etc. RESULTS:Of 114 serious ADR cases,the number of female was more than that of male(71/43). Patients aged 21-30 years old took up the greatest proprotion(35 cases,30.70%). The main involved primary disease was schizophrenia(54 cases,47.37%). Oral adminis-tration-induced ADR was most common(103 cases,90.35%). The main involved drugs were antipsychotics,occupying the great-est proportion(75 cases,65.79%). Digestive system involved was the most common(53 cases,42.74%), Olanzapine tablets had the highest incidence of serious ADR (23 cases,18.55%),the main clinical manifestation were both abnormal liver function. There were 8 cases of new serious ADR (7.02%). Most of the ADR can be cured after drug withdrawal or countermeasures,no death case was found. CONCLUSIONS:Psychiatric drugs can induce serious ADR as treat psychiatric disease,among which the in-cidence of ADR induced by Olanzapine tablets is the highest and mainly manifestes digestive system symptoms. It is suggested to strengthen serious ADR monitoring to promote the safe use of drugs.

Objective To observe the clinical efficacy of Qianyang Mixture for the treatment of perimenopause hypertension. Methods Eighty cases of perimenopause hypertension patients were randomly divided into treatment group and control group, with 40 cases in each group. The two groups were given Amlodipine Besylate Tablets for oral taking, one tablet each time, once a day. The treatment group was treated with Qianyang Mixture, 35 mL for each time, twice a day, 1 h after meal. Course of treatment was 12 weeks. The changes of blood pressure, heart rate and sex hormone level of patients in both groups were observed, and efficacy of TCM syndrome were evaluated. Results After treatment, the heart rate, average daily blood pressure and morning blood pressure of the treatment group were lower than those of the control group, with statistical significance (P<0.05);After the treatment, the levels of estradiol in the treatment group were higher than those in the control group, with statistical significance (P<0.05). The total effective rate was 92.5% (37/40) in the treatment group and 80.0% (32/40) in the control group, with statistical significance (P<0.05). Conclusion Qianyang Mixture can obviously reduce blood pressure and heart rate of patients with perimenopause hypertension, and can regulate hormone levels, improve TCM symptoms.

ABSTRACT:Objective To study the expressions of adrenomedullin (ADM)andβ-catenin in human osteosarcoma of different differentiation grading and their clinical significance.Methods We chose 33 cases of human osteosarcoma with different pathological grading (14 cases of high differentiation grading and 1 9 cases of low grading)and 10 cases of human osteochondroma to detect the expressions of ADM protein,total (T)β-catenin and phosphorylated (P)β-catenin using immunohistochemical method. Results The expression of ADM was detected in the cytoplasm.In osteosarcomas of higher and lower differentiation grading,the positive rate of ADM was 57.1% (8/14)and 100% (1 9/1 9),respectively,with significant differences (P =0.003<0.05).The expression of T-β-catenin was observed in both the cytoplasm and the nucleus in higher differentiation grading and in only cytoplasm in lower grading.In osteosarcomas of higher and lower differentiation grading,the positive rate of T-β-catenin was 85.7%(12/14)and 94.7% (18/1 9),with no significant difference (P =0.561>0.05).The expression of P-β-catenin was detected in the cytoplasm.In osteosarcomas of higher and lower differentiation grading,the positive rate of P-β-catenin was 35.7% (5/14)and 78.9% (1 5/1 9),with a significant difference (P =0.029 <0.05).There was a significant correlation between ADM and P-β-catenin (r =0.424,P =0.025<0.05),but no significant correlation between ADM and T-β-catenin (P = 0.078 > 0.05 )or between T-β-catenin and P-β-catenin (P = 0.052 > 0.05 ).Conclusion The expressions of ADM and P-β-catenin proteins and the different distributions of expression of T-β-catenin protein in cytoplasm and/or nucleus are important indicators for judging the pathological grading of osteo-sarcoma.
