Artemisinin and its derivative is a kind of efficient,quick and low toxicity of anti-malarial drug.In recent years,we find that artemisinin drugs can not only against malaria,but also have pharmacological effects of immunosuppression,antiviral and anticancer.A number of studies have confirmed that artemisinin and its derivatives have the radiosensitization effects in nasopharyngeal carcinoma,cervical cancer,lung cancer and glioma,and their mechanisms are related to decreasing Weel protein expression,increasing Cyclin B1 protein expression,blocking G2-M phase and cell apoptosis.

Objective: To establish a method for determining the content of dracorhodin as an indicator in the quality control with methodological studies to provide basis for the preparation process study of Qilisan gel. Methods: An HPLC method was used with a DiamonsilR C18 (250 mm ×4. 6 mm, 5 μm) column, the detection wavelength was set at 440 nm and the column temperature was 30 ℃. Acetonitrile-0. 05 mol·L-1 sodium dihydrogen phosphate solution (45 ∶ 55) was used as the mobile phase, and the flow rate was l. 0 ml·min-1 . Results: The content of dracorhodin was in a good linear relationship (r =0. 999 6) within the range of 1. 632-64. 250 μg·ml-1 , and the average recovery was 99. 02%(RSD =0. 77%, n =6). The number of theoretical plates was calculated as 7 100 according to the dracorhodin perchlorate peak without any interference from the negative sample. Conclusion: The method is objective, accurate and sensitive with high reliability, easy operation and fast process. The measurement results can be used as the quality control basis for the preparation process study of Qilisan gel.

Objective To investigate the relationship between the expressions of angiotensin converting enzyme 2(ACE2)/ACE mRNA in myocardium-nephors and the blood pressure in spontaneously hypertensive rats (SHR).Method A total of 18 male of 12 weeks old SHRs and 18 male of 12 weeks old Wistar Kyoto(WKY)rats were got for the experimental study.Nine SHRs and 9 WKY rats were randomly taken out as controls and sacrificed for detecting the mRNA expressions and protein of ACE2 and ACE.Other halves of rats of both groups were fed for 12 weeks and then sacrificed for detecting of the same biomarkers as in controls.The mRNA expressions of ACE2 and ACE were determined by real-time quantitative RT-PCR.The protein level of ACE2 and ACE were determined by immunohistochemistry.Results Systolic blood pressure(SBP)in SHRs of 12 and 24 weeks old increased compared with that in WKY(all P＜0.01).SBP in SHRs of 24 weeks old increased compared with that in SHRs of 12 weeks old(P＜0.01).The cardiac and renal expressions of ACE2 mRNA in SHRs of 12 and 24 weeks old were all significantly lower than those in WKY rats(P＜0.01).The expressions of ACE mRNA in SHRs of 12 and 24 weeks old were all significantly higher than those in WKY rats(P＜0.05,P＜0.01).The cardiac and renal expression of ACE2 mRNA in SHRs of 24 weeks old was significantly lower than that in SHRs of 12 weeks(P＜0.01).The myocardial and renal expression of ACE mRNA in SHRs of 24 weeks old was significantly higher than that in 12 SHRs of weeks old(P＜0.01).The positive reactions of ACE2 protein found in kidney displayed in brown colur.The ACE2 proetin appeared in uniform distribution of brown granules in WKY rats and comparatively scanty distribution of brown granule in SHRs.Conclusions There are correaltions between the expressions of ACE2/ACE mKNA as well as protein and blood pressure.

OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

Objective To investigate the correlation of blood-brain barrier (BBB) damage and depression in patients with cerebral small vessel disease (CSVD).Methods Consecutive patients with CSVD admitted to hospital were enrolled prospectively.The patients completed head MRI and cerebrospinal fluid (CSF) examination after admission.The BBB damage degree was evaluated by using albumin CSF/serum ratio (Q-Alb).At 3 months after onset,the depression was assessed according to the Hamilton depression scale (HAMD) and the American Diagnostic and Statistical Manual of mental disorders,4th edition (DSM-Ⅳ).The correlation between the BBB damage and depression in patients with CSVD was analyzed,Results A total of 130 consecutive patients with CSVD were enrolled,including 58 (44.62％) had depression within 3 months.There were significant differences in the proportions of patients with lacunar infarction (43.10％ vs.26.39％;x2 =4.008,P =0.045),leukoaraiosis (75.86％ vs.58.33％;x2 =4.408,P =0.036),and cerebral microbleed (27.59％ vs.12.50％;x2 =4.707,P =0.030),and baseline National Institutes of Health Stroke Scale (NIHSS) scores (5.02 ± 2.51 vs.3.60 ± 2.43;t =3.256,P =0.001),Fazekas scales of deep white matter (2.35 ± 1.00 vs.1.56 ± 1.05;t =4.358,P ＜0.001) and the proportion of Q-AIb category (x2 =6.852,P =0.033) between the depression group and the non-depression group.Multivariate logistic regression analysis showed that the baseline NIHSS scores (odds ratio [OR] 1.248,95％ confidence interval [CI] 1.027-1.517;P =0.026),leukoaraiosis (OR 14.786,95％ CI 1.776-123.111;P=0.013),Fazekas scales of deep white matter (OR 1.847,95％ CI 1.210-2.819;P=0.004),and Q-Alb (OR 30.417,95％ CI 3.662-252.643;P =0.004) had significant independent correlation with depression.Conclusions The BBB damage is independently associated with depression in patients with CSVD.

Objective To determine whether homocysteine(Hcy)and monosodium glutamate (MSG)could lead to animal model of hypertensive disorder complicating pregnancy and its mechanism. Methods Female adult Wistar rats were randomly divided into 4 groups:pregnant control group(PN), pregnant Hcy group(PH),pregnant glutamic acid group(PG)and pregnant Hcy and glutamie acid group (PHG).The rats of each group were injected with Hey 200 mg/kg or physiological saline every day intraperitoneally and with MSG or 0.9% saline every other day via Hcy injection from the 10th day to the 20th day of pregnancy.The blood pressure,urine protein,function of liver and kidney,weight of placenta, length and weight of fetus were all measured.The histological change of the pallium and the change of behavior of pregnant rats were also observed.Results(1)The blood pressure in PH[(107?8)mm Hg, 1 mm Hg=0.133 kPa],and PHG group [(109?10)mm Hg] after the treatment increased significantly compared with those in other groups from the 12 th day after pregnancy(P

Objective To evaluate the safety of coronary intervention using iodixanol in patients with diabetic renal insufficiency.Methods Clinical data of 97 patients with diabetic renal insufficiency undergoing coronary intervention during June 2004 to June 2006 were retrospectively analyzed,50 of them with iodixanol,an iso-osmolar contrast medium (iodixanol group),and 47 with iopromide,a hypotanic contrast medium (iopromide group).Judkin's coronary angiography showed 167 diseased vessels in the patients,65 in anterior descending branches,44 in circumflex branches,and 58 in right coronary arteries. Levels of serum creatinine and blood urea nitrogen were determined before percutaneous coronary intervention (PCI),on the day of the procedure,the 3rd and 7th days after PCI,respectively,as well as radiocontrast media-induced nephropathy (CIN) was observed.Results Totally,192 drug-eluting stents were successfully implanted in 167 diseased vessels,and all patients' angina pectoris symptom disappeared soon after the procedure,with a full success.No acute or subacute stent thrombosis and major adverse cardiac events (MACE) occurred.Two patients (4%) in iodixanol group and 10 (21%) in iopromide group got CIN,with a statistical significance (P

Objective To analyze safety,efficacy and resection methods of video-assisted thoracic surgery(VATS) for the treatment of intralobar pulmonary sequestration(IPS).Methods Data of 17 patients who were diagnosed as IPS and received VATS from December 2006 to September 2011 were retrospectively analyzed.The patients were 7 males and 10 females with the mean age of 40.3 (14-61) years.Diagnosis was confirmed in 9 patients by enhanced CT and unconfirmed in 8 patients.Three ports were used for surgery.After the aberrant artery was confirmed,liner stapler was used in 16 patients to cut it and Hem-o-lok was used in 1 patient because the aberrant artery was about 3 mm in diameter and long enough.If the diameter of the aberrant artery was longer than 10 mm,a stapling device without knife was used to occlude it centrally and a second stapling device was used to cut it peripherally.Wedge resection or lobectomy was performed due to the different conditions.When the lesion was small with linited range in CT image and the lesion was easily distinguished from normal lung tissue during operation,wedge resection was preferred.Results Seventeen patients underwent VATS successfully without any conversion to thoracotomy or any serious complications.Five patients were planned to receive wedge resection and one was converted to lobectomy.Another 12 patients were planned to receive lobectomy and all succeeded.The mean operating time was 128 (80-170)min.The mean blood loss was 80 (5-200) ml.The mean days of chest tube maintained were 4.0 (2-6) days.The mean postoperative hospitalization days were 7.6 (4-11) days.All patients were diagnosed as IPS according to operating in-sight and postoperative pathology.There was no patient suffering from chronic cough,bloody sputum or recurrent pneumonia during the follow-up.Conclusion VATS for the treatment of IPS is safe and feasible.If conditions permit,wedge resection or segmentectomy may be preferred.
