Two cardenolide glycosides, corotoxigenin 3-O-[β-D-glucopyranosyl-(1→4)-6-deoxy-β-D-glucopyranoside] (1) and coroglaucigenin 3-O-[β-D-glucopyranosyl-(1→4)-6-deoxy-β-D-glucopyranoside] (2), were isolated from the seed fairs of Asclepias curassavica. The structures of 1-2 were determined based on the combination of the analysis of their MS, NMR spectroscopic data and acid hydrolysis. The inhibitory effects of compounds 1 and 2 on human colorectal carcinoma cells (HCT116), non-small cell lung carcinoma cells (A549) and hepatic cancer cells (SMMC-7721) were evaluated. The results showed that both compounds 1 and 2 significantly inhibited the viability, proliferation, and migration of A549, HCT116 and SMMC-7721 cells, suggesting that compounds 1 and 2 can be applied in the treatment of lung, colon and liver cancers in clinical practice. This study may not only provide a scientific basis for clarifying the active ingredients in A. curassavica, but also help to understand its antitumor activity, which can promote the application of A. curassavica in clinical treatment of various cancers.

Objective:To make the early clinical antibiotic regimen by finding out the infection of corynebacterium in the pus of patients with granulomatous mastitis in the early stage.Methods:A total of 42 patients who were diagnosed and treated in the Breast Center of Guangdong Maternal and Child Health Hospital from Jun. 2016 to Mar. 2017 with complete follow-up data were retrospectively analyzed. PCR method was used to detect corynebacterium in the patients’ pus. Patients in the positive group were treated with antibiotics alone, antibiotics + hormones and hormones alone, while patients in the negative group were treated with antibiotics + hormones and hormones alone. The postoperative recurrence rate and cure rate of different groups of patients were observed.Results:The antibiotic regimen for granulomatous mastitis in patients with corynebacterium infection included a combination of short-acting levofloxacin and azithromycin and long-acting anti-mycobacterium drugs. Among the 42 patients in the subgroup, 21 patients were confirmed positive for corynebacterium by PCR detection of pus, and the postoperative recurrence rate was 23.5%. There was a statistically significant difference between the antibiotic group, the antibiotic + hormone group and the hormone group in treatment of granulomatous mastitis infected with corynebacterium ( χ2=5.494, P=0.036) . PCR detection shouwed corynebacterium negative in 21 cases, and postoperative recurrence rate of 16.7%. No statistically significant difference in efficacy was found between antibiotic + hormone group and hormone only group for GM patients without bacterial infection ( χ2=1.129, P=0.719) . Conclusion:Early detection of corynebacterium infection in GM patients is significant for clinical guidance of the application of lipophilic antibiotics.

Objective To evaluate the usefulness of narrow-band imaging with magnification in differentiating colorectal lesions, and assess for a learning curve, to gave help for the clinician, who want to carry out the technique. Method We retrospectively analyzed the clinical data of 289 patients who underwent NBI combined with magnification by four endoscopic physician, from June, 2015 to June, 2016, all the lesions were biopsied, endoscopic treatment or postoperative pathology and pathological examination, and the Sano classification control. All lesions were divided into three groups according to the NBI combined with magnifying endoscopy, these three sets included both lesions requiring endoscopic treatment (e.g. target lesions) and lesions that were not, or could not be, treated by endoscopy (e.g. nontarget lesions). Each physician examined the target or non-target lesion reached 15 cases as a group. By assessing the diagnostic accuracy of the four physicians for each group of lesions, an associated learning curve of NBI combined with magnifying endoscopy was developed. Result In 289 patients, 372 lesions were found by colonoscopy. NBI combined with magnifying endoscopy was 95.1%, 98.0% and 92.0%, respectively, in the identification of tumor and non-neoplastic lesions. The accuracy of the diagnosis of target and non-target lesions was significantly higher in group 2 than in group 1 [81.7% vs 95.1% (P = 0.010) and 71.7% vs 93.4% (P = 0.000)]. There was no significant difference in the diagnostic accuracy between group 2 and group 3 (P = 0.984 and P = 0.117). Conclusion It is very useful to use narrow-band imaging and Sano CP analysis in the differential diagnosis of colorectal lesions. The endoscopists who had never used NBI or no knowledge of NBI can have effective and stable diagnostic accuracy after using NBI with magnification to diagnose 15 target and non-target lesions respectively.

Objective To explore the establishment of a rat model of acute radiation-induced liver injury and sig-nificance of the dynamic changes of TGF-β1 expression.Methods Forty healthy 6-week old male SD rats were randomly divided into model group (n=30) and control group (n=10).The right liver of rats in the model group was given a single dose of 25 Gy 6 MV X-ray irradiation.Histopathological examination using HE staining and transmission electron microsco-py were conducted to observe the liver pathological changes in rats at 3, 5, and 10 days after irradiation, serum TGF-β1 was detected, and relevant indicators of liver function ( ALT, AST, ALP) were determined.Statistical analysis was per-formed using SPSS 17.0 software.Results At 3, 5 and 10 days after irradiation, early pathological changes in the liver cells were observed by electron microscopy, the expression of TGF-β1 was gradually increased with the time prolongation, and significant differences were found between the model group and the control group at different time points (P<0.05). The light microscopic observation of liver tissues did not show significant differences between the control group and model group.The liver ALT, AST, ALP at different time points did not show significant differences between the two groups ( P>0.05).Conclusion Electron microscopy can be used to evaluate the early changes of radiation-induced liver injury, pri-or to the alterations visible by routine light microscopy.TGF-β1 can be used to predict the degree of radiation-induced liver injury, and may be used as a sensitive serum cytokine in predicting the degree of radiation-induced acute liver injury.

To observe the curative effect of treating small -incision cataract extraction by intraocular lens implantation combined with trabeculectomy for primary angle-closure glaucoma with cataract.
●METHODS: Totally 44 cases (52 eyes) of primary angle-closure glaucoma combined with cataract were selected to undergo the combined surgery, in order to observe the patients' pre - and postoperative eyesights, intraocular pressures and the postoperative complications.
●RESULTS: The postoperative eyesight was improved significantly as compared with the preoperative eyesight. The intraocular pressure was declined dramatically. The result was of statistical significance (P<0. 05). All the 52 cases' surgeries were performed by the same surgeon. The surgeries were processed smoothly, with 6 postoperative eyes of anterior chamber inflammation cell response, 3 eyes of anterior chamber fibrinoid exudate, 2 eyes of shallow anterior chamber through mydriasis and treatment with glucocorticoids and non - steroidal eyedrops before absorption, and no complications like malignant glaucoma, cyclodialysis, etc. were reported through mydriasis and pressure bandaging before recovery.
