ABSTRACT
@#Objective To explore the independent risk factors for postoperative retention of urinary catheters in the ward of lung tumor patients due to urinary retention under the concept of enhanced recovery after surgery (ERAS). Methods Seventy-five patients with lung tumors who had urinary catheters left in the postoperative ward between June 2019 and August 2019 were selected as a case group, and 75 patients with lung tumors who did not have urinary catheters in the perioperative period as a control group. Independent risk factors for indwelling urinary catheters in the postoperative ward were screened by univariate and multiple-variate logistic stepwise regression analysis. Results There were 45 males and 30 females in the case group with an average age of 55.33±10.78 years, 28 males and 47 females in the control group with an average age of 57.12±10.06 years. Univariate analysis showed that gender, operative time>2 h, intraoperative fluid volume≥1 200 mL, and fluid volume within 6 h of returning to the ward after surgery>1 200 mL were associated with the occurrence of indwelling urinary catheters in patients with lung tumors in postoperative wards (P<0.05). Multiple-variate logistic regression showed that male (OR=2.311, 95%CI 1.173-4.552, P=0.015), infusion volume within 6 h of returning to the ward after surgery>1 200 mL (OR=2.491, 95%CI 1.149-5.401, P=0.021) and intraoperative infusion volume≥1 200 mL (OR=2.105, 95%CI 1.022-4.340, P=0.044) were independent risk factors for postoperative retention of urinary catheters in patients with lung tumors. Conclusion The occurrence of indwelling urinary catheter in lung tumor patients under the ERAS concept is the result of a combination of factors, and patients who are male, have infusion volume>1 200 mL within 6 h of returning to the ward after surgery, and have intraoperative infusion volume≥1 200 mL are the high-risk group for postoperative ward indwelling urinary catheter, and health care personnel should strengthen the assessment and observation, provide targeted health education, appropriately control the perioperative fluid volume, and take other measures to reduce the occurrence of indwelling urinary catheters due to urinary retention postoperatively in ward.
ABSTRACT
@#Objective To investigate the occurrence of indwelling urinary catheter in patients receiving thoracoscopic lobectomy and relevant risk factors. Methods We retrospectively reviewed the clinical data of the 737 patients who received thoracoscopic lobectomy in our hospital and analyzed the risk factors of indwelling urinary catheter during postoperative hospitalization using univariate analysis and multiple-variate logistic regression analysis between December 2018 and May 2019. There were 253 males and 484 females at median age of 57 (50, 64) years. Results A percentage of 14.4% (106/737) of the patients adopted postoperative indwelling urinary catheter. Univariate regression analysis showed that gender and postoperative bedridden time were risk factors for indwelling urinary catheter in the patients after thoracoscopic lobectomy (P<0.05). Multiple-variate logistic regression analysis showed that male gender (OR=2.018, 95% CI 1.316-3.096, P<0.001) and postoperative bedridden time >18 hours (OR=2.298, 95%CI 1.502-3.516, P<0.001) were the independent risk factors for indwelling urinary catheter. Conclusion Male gender and those with longer postoperative bedridden time are high-risk population to indwell urinary catheter. Positive measures should be taken to reduce the chance of indwelling urinary catheter.
ABSTRACT
Objective:To evaluate the effects of several kinds of surface treatment methods on the bond strength of zirconia prosthesis,and to provide references for improving the bond strength of zirconia prosthesis.Methods:Sixty zirconia blocks(10 mm×10 mm×2 mm) were divided into 6 groups according to the surface treatment methods:sandblasting,silica coating,Z-PRIME Plus,sandblasting+Z-PRIME Plus,sandblasting+silica coating,and silica coating+Z-PRIME Plus groups.The zirconia-resin specimens were fabricated using ScotchbondTM Universal;shear bond test was performed to detect the shear bond strength after treated with water storage(37℃) for 24 h by universal mechanical testing mechine;the fracture types were observed by stereoscopic microscope.One fracture specimen was randomly chosen from each group,and the morphology of the specimen was examined under scanning electron microscope.Results:The shear bond strength of the specimen in Z-PRIME Plus group was higher than those in the other groups(P<0.05).The adhesive failure was predominantly observed in sandblasting,silica coating,sandblasting+silica coating and silica coating+Z-PRIME Plus groups.There were 4 cases of mixed failure in Z-PRIME Plus group and there were 8 cases of mixed failure in sandblasting+Z-PRIME group.No cohesive failure was observed in all the groups.The scanning electron microscope results showed that the fracture surface occurred on the resin-zirconia interface of the specimens in sandblasting group,Z-PRIME Plus group,and sandblasting+Z-PRIME Plus group.The silica-zirconia fracture of specimens occurred in silica coating group and silica coating+Z-PRIME Plus group.The silica-resin interface fracture of specimens partially occurred in sandblasting+silica coating group.Conclusion:The application of Z-PRIME Plus can significantly improve the bond strength between zirconia and resin.
ABSTRACT
Individual identification by m easuring the hum an skeleton is an im portant research in the field of forensic anthropology. C om puted tom ography (C T ) technology can provide high-resolution im age of skeleton. Skeleton im age can be reform ed by softw are in the post-processing w orkstation. D ifferent skele-ton m easurem ent indexes of anthropology, such as diam eter, angle, area and volum e, can be m easured on section and reform ative im ages. M easurem ent process is barely affected by hum an factors. T his paper review s the literatures at hom e and abroad about the application of m easuring skeleton by C T in foren-sic anthropology research for individual identification in four aspects, including sex determ ination, height infer, facial soft tissue thickness m easurem ent and age estim ation. T he m ajor technology and the applica-tion of C T in forensic anthropology research are com pared and discussed, respectively.
ABSTRACT
Curcumin has been reported to possess antitumor activity with low toxicity. However, the clinical application of curcumin has been significantly limited by its instability and poor metabolic property. In order to overcome these limitations and discover novel small molecules with potential antitumor activity, 29 curcumin mimics were synthesized, which were confirmed by 1H NMR and HR-MS, and their cytotoxic property was evaluated against five human cancer cell lines in vitro. Compounds 16, 18 and 19 exhibited good cytotoxic property, their IC50 value were even below 5 micromol x L(-1) to some cancer cell lines, 5-9 times better than curcumin.
ABSTRACT
ObjectiveTo investigate the protective effect of combination of triptolide and irbesartan on the podocytes in a type 2 diabetic(T2DM) rat model,and evaluate its mechanism.Methods T2DM rats were induced by fed with high-sucrose-high-fat diet combined with a low dose of streptozocin.The rats were randomly divided into 5 groups:normal control group ( NC,n =10),diabetes group ( DM,n =11),triptolide treatment group (DT,n =12),irbesartan treatment group (DI,n =12) and triptolide combined with irbesartan treatment group (DTI,n =13). Ultrastructure of podocytes was observed by electronic microscopy and urinary albumin (UAL) excretion by ELISA was determined after 8 weeks.The expression of nephrin and bone morphogenetic protein-7(BMP-7), connective tissue growth factor (CTGF),transforming growth factor (TGF)β1 mRNA and proteins were detected by immunohistochemistry,real-time PCR and Western blot. Results Increased UAL was significantly attenuated in all treatment groups.Compared to NC group,UAL in DM group was increased significantly (0.45 ± 0.09 vs 6.36 ± 0.87,P ＜ 0.01 ),while decreased in triptolide or irbesartan alone treatment group (2.48 ± 0.37 and 2.68 ±0.42,both P ＜ 0.01 ).Compared with those in control groups,kidney expression of nephrin,BMP-7 mRNA and proteins were downregulated while CTGF, TGFβ1 mRNA and proteins were significantly upregulated in T2DM rats. Triptolide or irbesartan each alone moderately ameliorated albuminuria and podocyte damage.However,their combined usage showed a dramatic therapeutic synergism,manifested by prevention of progressive albuminuria,restoration of the glomerular filtration barrier,reversal of the decline in slit diaphragm proteins,reduction expression of CTGF,TGFβ1,and upregulation of BMP-7.Conclusion Our findings show that triptolide can increase the efficacy of irbesartan,leading to a more effective prevention of kidney disease in T2DM rat model,which may through upregulation of BMP-7 and inhibition the overexpression of CTGF and TGFβ1.

ABSTRACT
Objective The study is designed to evaluate the difference in identification for depression and clinical effectiveness of its treatment between psychiatrists and non-psychiatric Dhysieians at out-patient departments of general hospitals and to analyze its related factors.Methods Totally,680 patients who visited psychiatric clinics in nine general hospitals of Shanghai at first time were screened by psychiatrists using Composite International Diagnostic Interview(CIDI)for depression and the screening resuhs were compared to the diagnosis made by non-psychiatric physicians as goal-keepers there.Altogether 297 patients with depression were recruited and assessed using Hamilton Depression Rating Scale(HAMD)and Hamilton Anxiety Rating Scale(HAMA).A self-made questionnaire for basic information was used to assess the ability for identification of depression in non-psychiatric physicians of general hospitals.Results Psychiatrists identified depression correctly in 337 of 680 patients who visited psychiatric clinics in general hospitals at their first visit,but non-psychiatric physicians only identified 216 patients,with statistically significant difference(χ2=30.73,P=0.000).A consistent agreement on depression diagnosis between the findings by psychiatrists and by CIDI was reached with Kappa of 0.774,but Kappa for that between the findings by non-psychiatric physicians and CIDI was 0.439.Effectiveness of treatment for depression by psychiatrists was better than that by non-psychiatric physicians,with higher total score and scores for each item of HAMD four,eight and 12 weeks after treatment,respectively(P＜0.05 or P＜0.01).Length of professional work of non-psychiatric physicians and annual time for professional training in management of mental disorders associated with their ability of identification for depression(P＜0.05).Conclusion Ability of non-psychiatric physicians to identify alQd cope with depression in the psychiatric department of general hospitals was insufficient,suggesting that more importance should be attached to the management of service quality at psychiatric department of general hospitals.
ABSTRACT
Objective To evaluate the semen quality of potential semen donors of college students and investigate their reproductive health status. Methods According to the screening procedure in the Basic Standard and the Technical Norms of Human Sperm Bank revised by Chinese Ministry of Health in 2003,all sperm samples of 355 potential donors were examined. Results 37 of 355 donors sperm(10.4%) were qualified to the normal standard revised by Chinese Ministry of Health;and the rest(89.6%) were abandoned,because the sperm numbers of 267 donors were not reached the identified semen standard of the human sperm bank in the first screen,26 donors(7.4%)were with abnormal health status,4 donors did not ejaculate and got samples,9 donors with normal semen quality did not take physical health examination,the normal shape percentage of 6 donors sperm was lower than 30% and the thawed revival percentage with(a+b) grade of 6 donors was lower than 60%.135 of 355 donors(38.0%) sperm quality were qualified to the male productive standard of WHO. Conclusion The results indicated that the sperm quality of undergraduate declines and the society should pay more attention to the reproductive health of college students.
ABSTRACT
Objective:To study the preventive and health effects of Ampelopsis grossedentata on hyperlipidemia. Method:Thirty Wistar rats were divided into three groups:control group, model group and test group. The control group was fed normal diet, while the model and test groups were fed high fat diet.The control and model group were given water while the test group was given water with 20% Ampelopsis grossedentata for 15 w. Serum lipids, hemorrheological indices, myocardial enzymes and IL-6 were measured. Results: At the end of experiment, serum TC, TG, LDL-C, and apoB/apoA, serum and myocardial MDA, myocardial enzymes activities, hemorrheological indices and serum IL-6 were obviously higher in model group while the activities of serum and myocardial SOD and GSH-Px were lower. In test group. serum TC, TG and apoB/apoA levels, serum and myocardial MDA, myocardial enzymes activities, hemorrheological indices, and serum IL-6 were significantly lower than those in model group, but HDL-C, SOD and GSH-Px activities higher. Conclusion:Ampelopsis grossedentata could significantly decrease blood lipids and hemorrheological indices of rats fed with high fat diet, and protect myocardial cells fromoxidation, and as a result to prevent hyperlipidemia and cardiovascular disease.
