OBJECTIVETo evaluate the effect of microwave sintering on the translucency of zirconia and to compare these effect with those of conventional sintering. The relationship between the microstructure of specimens and translucency was investigated.

METHODSA total of 10 disc-shaped specimens were fabricated from 2 commercial brands of zirconia, namely, Zenostar and Lava. Each group included 5 discs. Conventional sintering was performed according to the manufacturers' specifications. The maximum temperature for Zenostar was 1,490 °C, whereas that for Lava was 1,500 °C. The dwelling time was 2 h. The sintering temperature for microwave sintering was 1,420 °C, heating rate was 15 °C · min⁻¹, and dwelling time was 30 min. After sintering, the translucency parameter (TP) of the specimens were measured with ShadeEye NCC. The sintered density of the specimens was determined by Archimedes' method. The grain size and microstructure of the specimens were investigated by scanning electron microscopy.

RESULTSDensity and translucency slightly increased by microwave sintering, but no significant difference was found between microwave and conventional sintering (P > 0.05). Small and uniform microstructure were obtained from microwave sintering. The mean TP of Lava was significantly higher than that of Zenostar (P < 0.001).

CONCLUSIONThe translucency of zirconia sintered by microwave sintering is similar to that of the zirconia sintered by conventional sintering.

Objective : To analyze the screening results of Mycobacterium tuberculosis (MTB) and HIV co-infections in Ningbo City from 2012 to 2020, so as to provide insights into improving the tuberculosis control strategy. Methods : Data pertaining to HIV antibody testing among tuberculosis patients, MTB testing among HIV/AIDS patients, treatment of patients with MTB and HIV co-infections and prognosis of anti-tuberculosis therapy were collected from the annual working reports for the management of MTB and HIV co-infections in Ningbo City from 2012 to 2020, and the screening, treatment and prognosis of MTB and HIV co-infections were analyzed. Results : A total of 35 385 newly identified tuberculosis patients were reported in Ningbo City from 2012 to 2020, and there were 5 854 cases receiving HIV testing. The annual mean percentage of HIV screening was 17.57%, and the HIV screening rate appeared a tendency towards a rise in Ningbo City from 2012 to 2020 (χ2trend=4 926.309, P<0.001). Eleven patients were tested positive for HIV, with an annual mean HIV positive rate of 0.19%. A total of 26 043 HIV/AIDS patients received MTB screening, with an annual mean screening rate of 95.78%, and the annual screening rate of MTB appeared a tendency towards a rise in Ningbo City from 2012 to 2020 (χ2trend=79.077, P<0.001). A total of 81 tuberculosis patients were detected, with an annual mean detection rate of 0.31%. Among the 92 patients with MTB and HIV co-infections, there were 81 patients receiving anti-tuberculosis and antiviral therapy simultaneously (88.04%), 8 cases receiving anti-tuberculosis therapy alone (8.70%), 2 cases receiving antiviral therapy alone (2.17%) and 1 case without therapy (1.09%). Among the 89 MTB and HIV co-infected patients receiving anti-tuberculosis therapy, 27 cases were cured (30.34%), 53 cases completing the course of treatment (59.55%) and 7 cases died. Conclusions The MTB screening rate among HIV/AIDS patients and the percentage of MTB and HIV co-infected patients with successful anti-tuberculosis treatment were high in Ningbo City from 2012 to 2020; however, the HIV screening rate should be improved among tuberculosis patients.

Objective To investigate the safety and efficacy on early treatment of large pancreatic pseudocyst by endoscopic ultrasound (EUS)-guided transgastric drainage. Methods The clinical data of 23 cases of large pancreatic pseudocyst treated with EUS-guided transgastric drainage from 2003 to 2008 was retrospectively analyzed. Results All were of single pseudocyst. Pseudocyst was present in the head of the pancreas in 3 cases, in the body of the pancreas in 11 cases, in the tail of the pancreas in 9 cases. Mean diameter of pancreatic pseudocysts was 11 cm( range 8 - 18 cm ). The interval between the finding of pseudocysts and EUS-guided transgastric drainage ranged 17 -65 d, averaging 31 d. Two had postoperative infection of the pseudocyst, one received percutaneons external drainage and the other one received surgical internal drainage. Three had postoperative gastrointestinal bleeding and were treated with antacid and hemostatic drugs. Patients were examined by CT two to three months later. Pancreatic pseudocysts disappeared completely in 6 cases and significantly shrank in the rest. The clinical symptoms of all patients,such as abdominal pain, abdominal bloating were significantly relieved. All patients were followed-up for 1 year, there was no pseudocyst recurrence, ulcer,bleeding or infection. Conclusions Early treatment of large pancreatic pseudocyst by EUS-guided transgastric drainage is safe and effective.

Objective To investigate the intermediate and long-term efficacy of endoscopic submucosal dissection (ESD) for early esophageal cancer(EEC).Methods A total of 56 patients with EEC underwent ESD at Jiangsu Province People's Hospital between April 2010 and June 2015.Among the 56 cases,there were 39 cases of intramucosal cancer,17 cases of submucosal cancer.Intravascular cancer embolus was found in 2 patients.The en bloc and complete resection rates,the residual,local tumor recurrence and new occurrence rates of EEC after ESD were evaluated.The average follow-up time was 24.4 months,ranging from 1 to 62 months.Results The en bloc and complete resection rates were 92.9％(52) and 87.5％ (49),respectively.Four patients were treated by additional esophagectomy.The cases of residual lesions,local tumor recurrence,new occurrence and second primary extra-esophageal cancer (gastric cancer) was 1 (1.8％),2 (3.6％),2 (3.6％) and 2 (3.6％),respectively.No additional surgical operations were performed in the 7 patients or no recurrence was found,and there was no death during the follow-up period.Conclusion ESD has the advantage of high complete resection rate,low residual and local tumor recurrence rate in treatment of EEC,and the intermediate and long-term outcomes are satisfactory.

We report in detail ultrastructural changes and freezing damage mechanism about heart muscle and some organelles after rapid freezing. The ventricles of rat heart were cut pieces about 100-150/?m by microsiicer. The pieces were quickly injected liquid cryogen Freon 22 by Reichert-Jung spring-assistant mechanism (KF-80). The specimens frozen were rapidly transferred into substitution medium aceton and kept at -80℃(28h), then -60℃ (48h),-20℃(12h)and 4℃ (1 h). The structures of specimens frozen were well and there were no ice crystals in the area of the tissue frozen surface to 20?m depth. However, there were freezing damages in mitochondrial crista, intercellular substance and muscular fibre in the tissue surface to 30?m depth. The structure of tissue was destroyed by ice crystal over 50?m depth in the tissue. The results suggest that intercellular substance and mitochondrial crista are the most sensitive to ice crystal damage after rapid freezing of heart tissue, then the less sensitive are muscular fibre and nucleus. The unit membrane is not easy to be damaged by ice crystal.
