Objective:To provide a scientific basis for the standardized operation of clinical disinfection by comparing and analyzing the influence of disinfection times on the accuracy of digital intraoral scanning.Methods:The author prepared 10 brand-new intraoral scanning heads (Trios, 3Shape, Denmark), scan the same plaster standard dentition model after 1, 20, 40, and 60 times of pressure steam sterilization, and obtained the data of four groups of experimental groups A, B, C, D, and scan the model 5 times repeatedly after each disinfection cycle of each scanning head. A model scanner (D2000, 3Shape, Denmark) was used to scan the standard dentition model, and the scan results were used as the control group data. Vernier calipers and measurement software were used to measure the arch length (the distance between the mesial cheek tips of the first molars on both sides of the maxillary) and the front and back length (the distance from the tongue protrusion of the right incisor to the buccal tip of the first molar on the right of the upper jaw) of the plaster model and the data of the 4 experimental groups. The line distance results of the 4 groups of experimental groups were compared for statistical analysis, and the trueness and precision values of the 4 groups of experimental groups were compared for statistical analysis.Results:The length of the arch across the 4 experimental groups increased with the increase in the number of disinfection ( P<0.05), and there were statistical differences compared with the measurement results of the plaster model ( P<0.05); the differences in the length of the dental arch were not statistically significant ( P>0.05). The treness of the 4 experimental groups is statistically significant ( P<0.05), and the trueness was from high to low in order of group A [(114.85±3.75) μm], group B [(124.65±3.85) μm], group C [(131.45±3.04) μm] and group D [(144.64±3.34) μm]; the precision of the 4 experimental groups was not statistically significant ( P>0.05). Conclusions:The number of times of pressure steam sterilization can affect the accuracy of the scanning results of the digital intraoral scanner, and with the increase of the number of sterilizations, the error of the scanning results also tends to increase. The number of sterilizations has no effect on the repeatability of the digital scanning results. The increase in the number of times of pressure steam sterilization affects the accross of the arch but has no effect on the length of the dental arch, and the range of change of the length of the arch is within the clinically acceptable range. After 60 times of pressure steam sterilization, the accuracy of digital scan data can still meet clinical needs.

Objective:To explore the influence of prognostic nutritional index (PNI) and controlling nutritional status (CONUT) on the prognosis of patients with multiple myeloma.Methods:Data of 157 patients with multiple myeloma (MM) at the affiliated hospital of Xuzhou medical university from January 2014 to December 2018 were retrospectively evaluated. The operating characteristic (ROC) curve analysis was adopted as the optimal cut-off point. PNI and CONUT were grouped based on the cut-off points of 44.45 and 3.5, respectively, and the differences between age, gender, serum calcium, β 2-microglobulin, serum creatinine, lactate dehydrogenase, and hemoglobin were analyzed. The prognostic factors were analyzed via univariate and Cox multivariate regression analyses. Results:The level of PNI and CONUT is the influencing factor of OS time. The univariate analysis revealed that age, LDH, plasma cell ratio, β 2-microglobulin, ISS stage, PNI, and CONUT were the risk factors for the prognosis of patients with MM. The multivariate analysis revealed that age ( HR=1.636, 95% CI 1.014-2.640) , plasma cell ratio ( HR=1.953, 95% CI 1.232-3.096) , and PNI ( HR=0.513, 95% CI 0.287-0.917) were the independent prognostic risk factors of patients with MM. Conclusion:Low PNI in patients with MM indicates a poor prognosis, which is an independent prognosis risk factor.

In this paper, the chemical composition and clinical application of malt were reviewed in order to provide reference for the development and application of malt related preparations.

Objective To investigate correlation between QT interval(QT),corrected QT interval(QTc) and metabolic syndrome(MS). Methods Residents who participated in our survey concerning atherosclerosis and related diseases conducted in Shenyang were included. They accomplished questionnaire,physical examination, laboratory tests and electrocardiography test. We divided them into MS group and non-metabolic syndrome (NMS)group according to International Diabetes Federation(IDF)diagnostic criteria for MS. QT interval was measured from the standard 12-lead electrocardiogram. QTc was calculated by using Bazett and Fridericia equations. We analyze correlation of QT ,QTc and MS. Results A total of 739 residents who were 35~64 years old were included. Individuals with MS had longer QTcB and QTcF than NMS group[(415.8 ± 31.9)ms vs.(410.1 ± 32.1)ms, (407.2± 29.1)ms vs.(402.6 ± 28.8)ms,P<0.05]. The more the number of abnormal MS parameters they had, the longer the QT,QTcB and QTcF they had. Regression analysis showed that QT was associated with serum potassium,smoking,blood glucose,and LDL,and QTcB and QTcF were associated with hypertension,waist circumference and blood potassium. Conclusions MS is associated with corrected QTc. Careful ECG monitoring among persons with MS for early detection of a long corrected QT interval may prevent severe and often fatal arrhythmias or sudden death.

BACKGROUND: Recent experimental studies have found ultrasound mediated microbubbles potentiate stem cell therapy in myocardial infarction (MI)-induced heart failure, indicating a good application prospect. But whether ultrasound mediated nitric oxide (NO) microbubbles also have the same effect in the intracoronary transplantation of bone marrow mesenchymal stem cells (BMSCs) for treatment of large animals with MI is still unknown. OBJECTIVE: To investigate the effectiveness and possible mechanism of ultrasound mediated NO microbubbles in potentiating intracoronally transplanted BMSCs homing to the infarcted area in a MI pig model.METHODS: Density gradient centrifugation culture method was used in the isolation and cultivation of BMSCs. CM-Dil was used to label BMSCs in vitro. Twenty-four pigs were used to make MI models by blocking the left anterior descending coronary artery, and then were divided into PBS group, BMSCs group, ultrasound+microbubbles+BMSCs(MB) group, ultrasound+NO microbubbles+BMSCs (NO-MB) group(n=6 per group). In the PBS group, 10 mL of PBS was intracoronally injected. In the BMSCs group, about 1×107 BMSCs were diluted in 10 mL of PBS and then intracoronally infused. In the MB group, 0.1 mL/kg sulphur hexafluoride microbubbles (Sono Vue) was intracoronally injected together with ultrasound treatment (1 MHz, 2 W/cm2, 2 minutes), followed by intracoronary infusion of about 1×107 BMSCs that were diluted in 10 mL of PBS. In the NO-MB group, all methods and conditions were identical to those in the MB group except only 0.1 mL/kg of Sono Vue was replaced by 0.1 mL/kg NO microbubbles. Three pigs were sacrificed in each group 48 hours after CM-Dil positive BMSCs transplantation. The labeled BMSCs were observed and counted by fluorescent microscope after frozen sectioning of the infarct area. We assessed and compared left ventricular systolic function with M-mode ultrasound among groups at 4 weeks after intervention. After cardiac function test, the rest pigs were sacrificed and capillary density in the myocardial ischemic area was counted and compared after hematoxylin-eosin staining. RESULTS AND CONCLUSION: (1) The number of CM-Dil positive cells in the area of MI in the NO-MB group was much more than that in the MB group and BMSCs group with statistical significance (P < 0.05). (2) The left ventricle systolic function was significantly improved in the NO-MB group as compared with the MB group (P < 0.05). The same trend was observed between NO-MB group and BMSCs group as well as between NO-MB group and PBS group (P < 0.05). (3) The density of capillaries increased significantly in the NO-MB group compared with the MB group, BMSCs group and PBS group, respectively. To conclude, ultrasound mediated NO microbubble combined with intracoronary BMSCs transplantation can improve the left ventricular systolic function. The possible mechanism could be that ultrasoundmediated NO mocrobubbles promote the homing of transplanted BMSCs to the myocardial ischemia area as well as improve local angiogenesis.

OBJECTIVETo evaluate the advantage and short-term efficacy of three-dimensional (3D) laparoscopic-assisted D2 radical gastrectomy for gastric cancer.

METHODSClinical data of 116 gastric cancer patients who underwent laparoscopic-assisted D2 radical gastrectomy in our department from January 2014 to August 2015 were analyzed retrospectively. Among 116 patients, 56 received 3D and 60 received two-dimensional(2D) technique respectively. All the surgeries were performed by the same team. The operative parameters, short-term efficacy and hospital expense were compared between the two groups.

RESULTSThere were no significant differences between the two groups in baseline data(all P>0.05). All the operations were performed successfully without conversion. Compared with 2D group, 3D group had shorter operative time [(186.2±22.8) minutes vs. (198.1±26.4) minutes, t=2.589, P=0.011], less intraoperative blood loss [(73.6±28.5) ml vs. (88.1±32.3)ml, t=2.555, P=0.012]. Whereas no significant differences in dissected lymph nodes(36.5±6.6 vs. 34.5±5.4, P=0.073), time to first flatus[(3.1±1.5) days vs. (3.3±1.8) days, P=0.729], length of hospital stay[(11.7±2.9) days vs. (12.6±3.1) days, P=0.088], incidence of postoperative complications [8.9%(5/56) vs. 11.7%(7/60), P=0.628] and hospitalization cost [(8.6±1.4)×10(4) yuan vs. (8.1±1.2)×10(4) yuan, P=0.055] were found between two groups.

CONCLUSIONThree-dimensional laparoscopic-assisted D2 radical gastrectomy may be advantageous over two-dimensional laparoscopic-assisted D2 radical gastrectomy.

Objective To investigate the clinical application of Glissonean pedicle transection method in hepatocellular carcinoma. Methods We analyzed the clinical data of 232 cases of hepatocellular carcinoma underwent hepatic resection in our department from April 2009 to April 2013. Eighty-nine cases underwent hepatic resection by Glissonean pedicle transection method, and 143 cases underwent Pringle maneuver. Results There was no significant differences in the operation time and blood loss between the two groups (P > 0.05). However, the postoperative hospital stay time and the postoperative complications in group A were better than those in group B(P<0.05). Levels of ALT and AST in group A increased significantly slowly than those in group B. The 1, 3-year disease-free survival rates in the two groups were 87.4%, 71.1% and 85.1%, 60.0%, respectively. The 1, 3-year survival rates were 93.3%, 73.5% and 93.4%, 65.0%, respectively, with no significant differences (P>0.05). Conclusion Glissonean pedicle transection method has many advantages including effectively preventing the intraoperative bleeding, maximally reserving the remaining of liver function, decreasing the rate of tumor spread and metastasis. Meanwhile, it is a safe and effective technique for hepatectomy without dissection of the hepatic artery, portal vein and bile duct in the hepatoduodenal ligament.

Objective To detect the positive rates of antibodies against avian influenza virus (AIV) subtypes H5, H6, H7 and H9 among people in poultry occupations in Guangdong province and to analyze the transmission of various subtypes of AIV from poultry to human contacts for the prevention and control of novel AIV infection in human beings.Methods Serum specimens were collected from 1066 peo-ple in poultry occupations ( occupational group) and 205 people not in poultry occupations ( non-occupational group) in 10 cities of Guangdong province.The inactivated AIV strains, isolated from poultry or environment of Guangdong province, were used as antigens to detect antibodies against AIV subtypes H5, H6, H7 and H9 by using the hemagglutination inhibition ( HI) assay.Results The positive rates of antibodies against AIV subtypes H5, H6, H7 and H9 carried by people from the occupational group were respectively 0.44%, 0%, 0.30%and 0.30%in 2013 and 1.08%, 0.0%, 0.0%and 0.27%in 2014.Only the anti-H9 anti-bodies were detected in serum samples collected form people in the non-occupational group in 2013 with a positive rate of 0.95%.No significant differences with the positive rates of anti-AIV antibodies were found between the occupational group and the non-occupational group.However, the geometric mean titer ( GMT) of anti-AVI antibodies in people from the occupational group was higher than that of the non-occupational group.Conclusion Although a grand spread of AIV from avian to human is not likely to happen yet, con-tacting with poultry is the risk factor for AIV infection in Guangdong population.A long-term surveillance of anti-AIV antibodies in serum should be strengthened among people in poultry occupations for the timely pre-vention and control of novel AIV outbreak.
