For the patients with early breast cancer,the effects of breast-conserving surgery combined with radiotherapy and radical resection are equal,and the former shows less adverse reactions and better aes-thetic outcome. Because of individual differences and the inherent complexity of tumor,to obtain optimal effects,it is an inevitable trend of making an individual comprehensive therapy,which is a combination of radiotherapy,chemotherapy,endocrine therapy and targeted therapy.

The electrochemical behaviors of parathion(PT) on nano-Al2O3 film modified electrode(nano-Al2O3/GCE/CME) were investigated. It was found that the redox peak currents of PT remarkably increased and the oxidation peak potential negatively shifted at the nano-Al2O3/GCE/CME. All the experimental parameters were optimized and a simple and sensitive electroanalytical method was developed for the determination of PT. The oxidation peak current was linear with the concentration of PT over the range from 2.5×10-9 to 1.0×10-7 mol/L and 1.0×10-7 to 1.0×10-5 mol/L. A low detection limit of 1.0×10-9 mol/L was obtained for 30 s accumulation at open circuit(S/N=3). The relative standard deviation(n=10) was 3.8% for 1×10-5 mol/L PT. The proposed method was used for the quantitative analysis of PT in some vegetables and the results were satisfactory.

Objective To explore the effects of prenatal exposure to lead on learning and memory of rats' offspring. Methods The pregnant rats were randomly divided into 4 groups provided with double evaporated water, 50, 100 and 200 mg/L lead acetate solution via drinking water respectively. The lead-exposure period for exposure groups was limited from the 1st day after pregnancy to the 20th day when the offspring began to be weaned. For learning ability 20-day old offspring were tested by water maze. For active learning and memory ability, the 20-day old, 40-day old and 60-day old offspring were tested by Y maze. Results The frequency of the mistakes in water maze made by offspring increased with the increase of the prenatal lead-exposure doses of their mothers and showed significantly higher levels in 100 and 200 mg/L groups compared with that of control group (P0.05). But the qualified rates of 0-min and 24-h escape for 100 and 200 mg/L groups showed sigificantly lower levels compared with that of control group when they were 60-day old (P

This report presented a case of 75-year-old woman who had received drug treatments two months earlier for nephrotic syndrome and was admitted to our hospital for inferior wall myocardial infarction with elevated creatinine and anemia.Kidney pathology after myocardial infarction showed allergic acute interstitial nephritis which induced acute renal failure.We stopped tripterygium glycosides and used cortical hormone,consequently.Thereafter,the symptoms of renal failure and anemia were improved and we considered tripterygium glycosides resulted in above allergic acute interstitial nephritis and anemia.Therefore,we had to carry out renal needle biopsy in the patient with the elderly nephrotic syndrome before confirmatory treatment to avoid blind use of tripterygium glycosides.

Objective To investigate the feasibility and clinical effects of the pair ringer technology for bony avulsion of the posterior cruciate ligament under arthroscopy. Methods From January 2005 to July 2009, 23 patients were treated with the pair ringer technology for bony avulsion of the posterior cruciate ligament by arthroscopy. There were 15 male and 8 female, with an average of 39.3 years (ranging from 28 to 52 years). There were 4 cases of type Ⅱ, 14 type Ⅲ, and 5 type Ⅳ according to Meyer-Mckeever classification. The outcome measures were X-ray and MRI testing, Lysholm and Tegner knee function score. Results All the operations were finished in an hour. There were no complications as nerve injury or infection occurred in the study. The patients were followed-up for an average of 16.5 months (12-23 months). The Lysholm score rose from 50.3±6.1 preoperatively to 89.7±8.3 at the six months postoperatively (t=18.34, P=0.0007). The Tegner score rose from 1.7±0.5 preoperatively to 5.7±1.3 at the six months postoperatively (t=13.77,P=0.0008). All of the patients recover a functionally stable knee and have considerably improved knee function compared with their preoperative status. Conclusion The pair ringer technology under arthroscopy is a liable method for bony avulsion of the posterior cruciate ligament. This minimally invasive technology leads to rigid fixation, early rehabilitation.

Huaier (Trametes robiniophila) has been widely used as an adjuvant drug for cancer treatment in China. The anti-cancer effect of Huaier extract has been confirmed in liver cancer, lung cancer, breast cancer, ovarian cancer, gastric cancer, and so on. The main mechanisms by which Huaier exerts an anti-neoplastic effect include inhibition of the growth and proliferation of cancer cells, induction of apoptosis of cancer cells, suppression of angiogenesis, inhibition of the invasion and migration of cancer cells, regulation of oncogenes and tumor suppressor genes expression, improving immunity, and reversal of drug resistance in cancer cells. In order to provide references for further study and clinical application on anti-tumor effect of Huaier, the latest research progress on anti-tumor effect of Huaier in recent years is summarized in this paper.

Objective To evaluate the potential effects of RS504393, CC chemokine receptor (CCR) 2b and CCR1 antagonist, on LPS-induced acute lung injury (ALI) and to investigate the underlying mechanisms. Method A549 cell line was stimulated with LPS (10 μg/mL) and then treated with RS504393 (10 μg/mL) for 6 hours. ALI model was established with intranasal administration of LPS (5 mg/kg) in C57BL/6J mice. RS504393 (5 mg/kg) was administered 30 min before LPS dripped nasally. IL-8, IL-1β, plasminogen activator inhibitor (PAI)-l,monocyte chemoattractant protein (MCP)-2,and the expressions of CCR1 and CCR2b were studied by using Realtime-RT-PCR, ELISA and cyto-flowmetry. Results In A549 cell line treated with RS504393,the expressions of CCR1, CCR2b and IL-8 were significantly inhibited after LPS stimulation. In rats with LPS-induced ALI, treatment with RS504393 significantly protected mice against lung injury by attenuating influx of leukocytes and protein into bronchoalveolar space and by lessening pathological changes of lung. Treatment with RS504393 down-regulated IL-1β and PAI-1 expressions in bronchoal veolar lavage fluid (BALF) and lungs at mRNA and protein levels along with up-regulation MCP-2 expression compared to rats of vehicle-treated groups. Conclusions CCR2b and CCR1 play pivotal roles in the development of ALl,and RS504393 as a antagonist can halt the development of ALI.
