ABSTRACT
BACKGROUND@#There is a certain correlation between vitamin nutritional status and cancer patients. Studies have shown that vitamin deficiency increases the risk of cancer. The purpose of this study is to understand the vitamin D nutritional status of cancer patients and to provide scientific basis for further nutritional intervention.@*METHODS@#Cancer patients who visited Shandong Cancer Hospital from July 2017 to June 2019 were included in this retrospective study. Serum 25-hydroxyvitamin D [25(OH)D] concentrations were measured. Univariate analysis and multiple linear regression analysis were carried out using SPSS 20.0.@*RESULTS@#A total of 2,487 cancer patients were evaluable for this analysis. Mean 25(OH)D concentration was (12.70±6.82) ng/mL; the prevalence of vitamin D deficiency [25(OH)D concentration less than 20.00 ng/mL] was of 92.20%. In univariate analysis, age, body mass index (BMI), season and types of cancer were associated with 25(OH)D concentrations. In the multivariate analysis, BMI (β=0.71), age (β=-0.56), season (β=-0.99 for winter; β=-0.76 for autumn vs summer) and types of cancer (β=-1.17 for lung cancer; β=-1.45 for esophageal-gastric cancer; β=-1.05 for colorectal cancer vs other types of cancer) were independently and significantly associated with 25(OH)D levels (P<0.05).@*CONCLUSIONS@#Vitamin D deficiency was highly prevalent among cancer patients. Age, BMI, season and types of cancer may be associated with 25(OH)D levels, which indicate that monitoring of vitamin D level for cancer survivor should be taken into account.

ABSTRACT
Oridonin is an en-kaurene diterpenoids compound which was found to have effect on tumor in vitro.But the clinical application has been limited because of poor water solubility,low bioavailability and oral absorption.Many scholars conducted a large number of structure modification researches of oridonin to search for new diterpenes with higher bio-activities and better bio-availabilities,and to develop new antitumor drugs.In this paper,studies on this aspect of oridonin were re-viewed.
ABSTRACT
Objective To investigate the relationship between hyperhomocysteinaemia and unstable angina pectoris (UAP). Methods Selected 159 patients with senile hypertension combined with angina pectoris from April 2013 to April 2014, 78 cases of hyperhomocysteinaemia patients as observation group, 81 cases of simple hypertension patients as control group. All of the patients were performed coronary angiography examination, using the Gensini score method calculated the integral of the coronary lesions (CAS). Detected the level of the serum homocysteine (Hcy), hypersensitive C-reactive protein (hs-CRP), fasting blood glucose (FBG) and blood lipid levels. Results The gender, age, the levels of FBG and lipid in two groups had no significant differences ( P>0.05). The incidence of UAP,CAS and hs-CRP in observation group were 44.9%(35/78), (44.34±10.67) scores,(4.31±1.01)μg/L, in control group were14.8%(12/81), (30.24±8.76) scores, (2.13±0.95)μg/L. The incidence of UAP, CAS and hs-CRP in observation group were significantly higher than those in control group ( P<0.05). The levels of serum Hcy,TC,TG,LDL-C, hs-CRP, HDL-C in UAP patients of observation group and control group were (23.21 ± 7.35) and (8.86 ±2.43) μmol/L, (6.54 ±0.75) and (6.67 ±0.82) mmol/L, (1.84 ±0.95) and (1.62 ±0.83) mmol/L, (4.65±0.78) and (4.42±0.72)mmol/L,(5.15±1.24) and(3.21±1.15) mg/L, (1.02±0.32) and(1.01±0.35) mmol/L. The levels of serum Hcy,TC,TG,LDL-C, hs-CRP, HDL-C in SAP patients of observation group and control group were (12.54±4.37) and (6.52±1.36)μmol/L, (4.23±0.54) and (4.43±0.57) mmol/L, (1.45 ±0.76) and (1.25 ±0.68) mmol/L, (2.67 ±0.45) and (2.43 ±0.43) mmol/L, (3.02 ±1.13) and (1.52±0.98) mg/L, (1.24±0.36) and (1.26±0.34) mmol/L.There were significant differences (P<0.05). Multi-factor Logistic regression analysis showed that the senile H-type hypertension was independent risk factor of UAP (OR=4.324, 95%CI 2.463-6.874, P=0.001). Conclusions The levels of serum Hcy is closely related to the stability of the coronary artery atheromatous plaque and lesion severity of coronary artery. The senile H-type hypertension is independent risk factor of UAP.

ABSTRACT
Objective To compare the efficacy between thoracoscopic and open cardiac surgery in the treatment of congenital heart diseases. Methods A total of 62 patients with congenital heart diseases were divided into two groups according to patients’ preference. There were 24 patients in the Thoracoscopic Group. The thoracoscopic operations were performed under extracorporeal circulation, including atrial septal defect repair in 8 patients and ventricular septal defect repair in 16 patients. The Open Group consisted of 38 patients, including atrial septal defect repair in 14 patients and ventricular repair in 24 patients. Results Fatal cases happened in neither of groups. There were no significant differences between the two groups in the bypass time (74?28 min vs 71?24 min; t=0.449, P=0.655), the ascending aorta cross-clamping time (29?13 min vs 28?12 min; t=0.309, P=0.758), and the postoperative mechanical ventilation time (3.2?1.1 h vs 3.3?1.1 h;t=-0.349, P=0.729), respectively. No significant variation in incidence of postoperative complications was observed between the two groups (?~2=2.646,P=0.104). As compared with the Open Group, the Thoracoscopic Group had a significantly less chest drainage volume (32?18 ml vs 66?28 ml;t=-5.290,P=0.000) and a significantly shorter postoperative hospital day (6.1?1.2 d vs 7.6?2.2 d;t=-3.059,P=0.003). Conclusions Thoracoscopic cardiac surgery for congenital heart diseases is a safe and effective technique with little invasion, quick recovery and good cosmetic results.
ABSTRACT
Aim To explore the effects and mechanism of ginsenoside-Rg1 on SK-N-SH cells treated with chronic morphine and naloxone-precipitated withdrawal. Methods Cells were pretreated with ginsenoside-Rg1 1,2,4,8,16,32 ?mol?L-1 for 24 h,then incubated for 24 h with morphine ( 100 ?mol?L-1 ) . MTT colorimetr was used to study the effects of ginsenoside-Rg1 on the multiplication of the cells treated with chro-nic morphine. After stimulated by the same concentra-tion of morphine,cells were added with different concentrations of Rg1 1,2,4 ?mol?L -1 for 24 h before stimulated with 10 ?mol?L -1 NAL. Fuorospectrophotometry RT-PCR and Western blot techniques were used to detect the effects of ginsenoside-Rg1 on the [Ca2+ ]i,CaMKⅡ ? mRNA and protein expression of the SK-N-SH cells treated with chronic morphine and naloxone-precipitated withdrawal. Results ① Compared with control group,morphine significantly inhibited cell multiplication and resulted in calcium overload,and the expression of CaMKⅡ-? mRNA and protein noticeably increased ( P

ABSTRACT
Objective To study the relationship of expression of angiopoietin gene and angiogenesis in the in-situ implanted hepatoma in rats. Methods Forty Wistar rats were used to establish the in-situ implanted hepatoma model by implanting Walker256 hepatoma cell line. The number of microvessel density(MVD) in hepatoma was calculated . The expression of angiopoietin mRNA was observed by in-situ hybridization method. Results The MDV in the implanted hepatoma in the first day of 1, 2 and 3 week postimplantatively were (15?4.3)/Hp,(17?3.6)/Hp,(45?7.8)/Hp respectively. The amount of MDV and expression of Ang-1 mRNA were increased significantly and correlated with MDV in the hepatoma tissues and non-hepatoma tissues,and no significant difference between the two types of tissues. Expression of Ang-2 mRNA was not seen in non-hepatoma tissues,but in hepatoma tissues,the expression of Ang-2 was obvious. Conclusions Angiopoietin-2 mRNA may play a role in the angiogenesis of the in-situ implanted hepatoma.
