OBJECTIVE:To evaluate the perioperative utilization of antibacterial drugs in patients undergoing modified radical mastectomy. METHODS: In this retrospective study, the perioperative utilization of antibacterial drugs in patients who underwent modified radical mastectomy during 2006 and 2006 were analyzed statistically. RESULTS: 100% of the patients received antibacterial drugs preventively. The problems involved in the preventive use of antibacterials manifested as medication without indications, irrational application of broad-spectrum antibacterials, frequent change of drugs, blind drug combination, inappropriate time of initial administration and prolonged drug use etc. CONCLUSION: The perioperative use of antibacterial drugs in patients undergoing modified radical mastectomy in our hospital is far from rational. The Clinicians' medication behavior should be standardized and supervision on rational drug use should be strengthened.

Objective To determine the change of maternal heart rate during the treatment with ritodrine for threatened premature labor. Methods110 cases of threatened premature labor were chosen. The ritodrine 100mg in 5% G. S 500mL was intravenously administered. The initial dosage was 6 drops/min, and the dose was increased until uterine contractions were inhibited. The treatment lasted for 40 to 48 hours after the uterine contractions were inhibited, then the oral tablets was recommended. If necessary, repeated treatment was given to some patients. The maternal heart rate was recorded in the whole process of treatment and was compared with the dosage administered. The labor time, fetal weight and Apgar′s score were also analyzed. Results The maternal basic heart rate was increased at first and then decreased. The increasing significantly increased( P ＜ 0.01 ) when the uterine contraction was inhibited. , but no difference showed among the groups of different gestational age( P＞0.05 ). The maternal heart rate was increased with the increasing of ritodrine( max. 140/min). labor time was significantly prolonged with the treatment of ritodrine( P＜0.01 ) ,while that of the idiopathic premature labor was prolonged most obviously ( P ＜ 0.05 ). Average fetal weight was (2.42 ± 0.49) kg, and the average Apgar′s score was≥8. Conclusion In the treatment of inhibiting uterine contractions,the increasing of maternal heart rate caused by ritodrine can be used as an indicator of therapeutic effect.

AIM: To quantitatively detect the expression level of transforming growth factor-β1 (TGF-β1) and transforming growth factor-β2 (TGF-β2) genes in the retina of normal rat in order to determine the expression difference of TGF-β1 and TGF-β2 in retina.METHODS: The total RNA was isolated from which the first strand of cDNA was prepared. The mRNA levels of TGF-β1 and TGF-β2 were detected quantitatively by real time polymerase chain reaction (PCR).RESULTS: The mRNA levels of TGF-β1 and TGF-β2 were 0.0008±0.0003 and 0.0378±0.009, respectively. Expression of TGF-β2 was obviously higher than that of TGF-β1 in rat retina with statistical significance (t=12.37, P<0.001). The ratio of TGF-β2/TG-β1 was 55.00±26.61.CONCLUSION: QRT-PCR could specifically and accurately detect gene expression level in rat retina. In retina the TGF-β2 gene was expressed more abundantly than TGF-β1. It is suggested that TGF-β2 play an important role in retina diseases.

AIM: To quantitatively investigate transforming growth factor-β type Ⅰ receptor (TβRⅠ) and transforming growth factor-β type Ⅱ receptor (TβRⅡ) gene expressions in rat retina.METHODS: Sprague-Dawley rats were chosen in this research. Gene expression was detected quantitatively by reverse transcription polymerase chain reaction (RT-PCR) analysis. RESULTS: The expression level of TβRⅠ and TβRⅡ were 0.00034±0.00013 and 0.0001±0.00005, respectively. The expression level of TβRⅠ was obviously higher than that of TβRⅡ in the rat retina with statistical significance (P<0.01). The ratio of TβRⅠ/TβRⅡ was 3.9±1.7.CONCLUSION: Real time quantitative RT-PCR is an effective method to detect differential expression genes in retina. The change of TβRⅠ/TβRⅡ expression may play an important role in the pathogenesis of retinopathy, which could be further investigated in its significance in the development of proliferation retinopathy.

AIM: To detect the gene expression of TGF-β2 in retinas of diabetic rats at different stages, to observe and analyze the effect of TGF-β2 on the retinas of diabetic rats, to explore the role of TGF-β2 in pathogenesis of diabetic retinopathy (DR), and to provide experiment data and experience for further clinic studies.METHODS: Sprague-Dawley (SD) rats were used and retinas were dissected. The total RNA was isolated from which the first strand of cDNA was prepared. Diabetes mellitus was induced by a single intraperitoneal injection of 60mg/kg streptozotocin (STZ) and the rats were held without insulin treatment until sacrifice. Besides, agematched rats treated with saline were used as controls. Tail vein blood glucose was measured after 2 days and rats were considered hyperglycemic if blood glucose reading>16.7mmol/L. Animals with blood glucose level<16.7mmol/L were excluded from the study. The rats were killed at the 4th, 8th, 12th, 16th, 20th and 24th week respectively after hyperglycemic models were established. The retinas were separated and preserved in liquid nitrogen. The expressions of TGF-β2 gene mRNA were detected by reverse transcription PCR (RT-PCR).RESULTS: The RNA of rat retina was integrative enough to be used to further carry out PCR analysis. Compared with control groups, the expression of TGF-β2 mRNA in retinas of diabetic rats was up-regulated at the 4th week, but there was no statistical difference (P>0.05); it was down-regulated at the 8th week, and there was statistical difference (P<0.05); it was also down-regulated at the 12th week, and there was statistical difference (P<0.05); at the 16th week there was no statistical difference (P>0.05); it was up-regulated at the 20th week, but there was no statistical difference (P>0.05); it continued to be up-regulated at the 24th week, and there was statistical difference (P<0.05).CONCLUSION: Since the expression of TGF-β2 mRNA in retinas of diabetic rats was down-regulated at the 8th week and 12th week statistically, up-regulated at the 24th week statistically, it has obviously shown that TGF-β2 was down-and up-regulated through the period of DR. That is, its changes are diphasic with time. It may confirm that TGF-β2, with the characteristic of diphasic regulation, played an important role in DR. It is necessary to study it furthermore.

Objective To investigate the effects of Xinnaoxuemianning combined with statins on carotid atherosclerotic plaque in patients with cerebral infarction. Methods 180 cerebral infarction patients were divided into the observation group (90cases) and the control group (90cases) by random number table method. The control group was given atorvastatin calcium tablets and the observation group was given additionally Xinnaoxuemianning. The changes and prognosis of carotid atherosclerotic plaques were evaluated before and after treatment, and the incidence of adverse reactions was counted. Results There were no differences in the carotid atherosclerotic plaque, TCM syndrome score and neurological deficit severity between the two groups before treatment. After treatment, the above indexes were significantly improved, and the increasing degree of the observation group was better than that of the control group. The incidence rate of adverse reactions was lower in the observation group than that in the control group (5.56％ vs.13.33％) (P<0.05). Conclusion Xinnaoxuemianning can reduce the carotid atherosclerotic plaque area and correct the unstable plaques in patients with cerebral infarction.
