Objective To investigate the impact of PET-CT on the target volume delineation and precise radiothera?py planning for patients with advanced non-small cell lung cancer (NSCLC). Methods PET-CT scanning was performed in 30 histologically proved NSCLC patients. The gross tumor volume (GTV) was delineated, and radiotherapy planning was es?tablished with identical parameters based on the CT image and PET-CT fused image, respectively. The differences of doses between GTV, planning target volume (PTV) and organsat rise (OAR) were compared. Results PET-CT image results changed the target volume delineation in 30 patients with 8 increased and 22 decreased. There were no differences in GTV and PTV between the VGTV and VPTV statistically, although PET-CT image changed conventional CT image size sketch of GTV and PTV. The V20 of total lung decreased in the PlanPET-CT compared with that of PlanCT (P<0.05), but no differences were found in the V30 of total lung, mean lung dose (MLD), the data of spinal cord, esophagus and heart. Conclusion PET-CT may reduce the radiation injuries in the lung and improve the target dose.

Objective: To study the anti hyperglycemic effect of rubusoside on diabetic rats induced by streptozotocin (STZ)and its mechanism . Methods: The STZ induced diabetic rats were dived into three groups and were given (ig.) saline, rubusoside and Phenformin respectively once a day. After three weeks, the levels of serum glucose, fructosamine, insulin,SOD were assayed. Results: Rubusoside could reduce the level of serum glucose significantly, enhance the ability of anti oxidation and stimulate the secretion of insulin in STZ induced diabetic rats. Conclusion: The action of rubusoside on secretion of insulin can be explained for the anti hyperglycemic effect.

Objective: To observe the effect of ticagrelor for non-ST-segment elevation acute coronary syndrome after percutaneous coronary intervention (PCI). Methods: A total of 200 patients with non-ST-segment elevation acute coronary syndrome after PCI were enrolled in this study.And the patients were randomly divided into the observation group (18 months treatment group, 100 cases) and control group (12 months treatment group, 100 cases) according to the digital table.The control group was given dual antiplatelet therapy (DAPT) for 12 months, and then, suspended the usage of ticagrelor.The observation group was treated by DAPT for 18 months.The major adverse cardiovascular events (MACCE) and the secondary end point events were observed. Results: The incidence rate of MACCE between the two groups had no statistically significant difference (χ²=0.298, P=0.862). And there was no statisticallysignificant difference in the incidence of the secondary end point events between the two groups (χ²=1.963, P=0.375). Conclusion The usage of DAPT beyond or equal 12 months doesn't reduce the incidence of MACC and it will not increase the blooding rate.The use of DAPT (aspirin and ticagrelor) should be used less than 12 months.

OBJECTIVE: To investigate the pre-pregnancy body mass index(BMI), gestational weight gain(GWG)and gestational outcomes in women with high normotension during pregnancy. METHODS: The clinical data of 1500 pregnant women who recieved antenatal care and delivered in Songjiang District Maternal and Child Hospital, Shanghai from 2015 to 2017 were retrospectively analyzed. The women were divided into high normotension group, normotension group and hypertensive disorder of pregnancy (HDP) group with 500 cases in each group. The general information, pre-pregnancy body mass index, gestational weight gain and gestational outcomes were analyzed. RESULTS: There were significant differences in pre-pregnancy BMI and GWG between the high normotension group and the normotension group (all <0.017), and there was significant difference in pre-pregnancy BMI between the high normotension group and HDP group (<0.017). In terms of adverse pregnancy outcomes, the incidence of oligohydramnios, placental abruption, postpartum hemorrhage, fetal distress and small for gestational age infant were higher in the high normotension group than those in the normotension group, but the differences were not of statistical significance (all >0.017); the incidence of oligohydramnios, placental abruption, cesarean section, postpartum hemorrhage, premature delivery and small for gestational age infant in HDP group were higher than those in high normotension group (all <0.01). In high normotension women with adverse gestational outcomes, the proportion of low GWG or too much GWG was higher and the proportion of normal GWG was lower than those in high normotension women without adverse gestational outcomes (all <0.01). CONCLUSIONS Pre-pregnancy BMI and GWG are correlated with pregnancy blood pressure and gestational outcomes. Reasonable intervention to gestational weight gain of pregnant women with high normotension is of significance to improve the gestational outcomes.

Objective:To investigate the predictive value of intra-abdominal pressure (IAP) combined with bedside index for severity in acute pancreatitis (BISAP) score on the severity and prognosis of acute pancreatitis (AP).Methods:In this retrospective study, 204 AP patients admitted to the Department of ICU, Second Hospital of Anhui University from Jan 2015 to Dec 2020 were divided based on the severity: into SAP group (145 cases) and Non-SAP group (59 cases) with end point survival (177 cases) and death (27 cases). The receiver operating characteristic (ROC) curves were drawn, and the predictive value of IAP, BISAP score and I-B (IAP and BISAP scores) in the severity and the prognosis of AP was studied. Medcalc software was used to compare the areas under ROC curve for different predictors.Results:IAP and BISAP scores increased with the severity of AP ( P<0.001), the area under the ROC curve (AUC) was 0.791, 0.749 and 0.907 respectively,comparison of area under ROC curve showed that I-B combined assessment was superior to IAP value and BISAP score alone in predicting severity ( P<0.05). IAP and BISAP scores were higher in the death group than in the survival group ( P<0.001). The ROC curve results of IAP, BISAP score and I-B combined on the prognosis of AP showed that the AUC was 0.773, 0.841 and 0.950, respectively,comparison of area under ROC curve showed that I-B combined assessment was superior to IAP and BISAP score alone in predicting prognostic value ( P<0.05). Conclusion:Both IAP and BISAP scores can better predict the severity of and the prognosis of AP, and the combination of IAP and BISAP score is more valuable for prediction of prognosis in AP.

In the process of continuous renal replacement therapy (CRRT), various factors such as the temperature of replacement fluid, the flow of fluid and the circulation of blood in cardiopulmonary bypass, lead to the temperature of the blood injected back into the body is often lower than normal. It leads to the decrease of body temperature and the occurrence of hypothermia, which can be life-threatening in severe cases. In clinical practice, medical staff mostly reduces the occurrence of hypothermia in patients with CRRT by means of the heating device of the machine, the heating of the liquid temperature box for cardiopulmonary bypass, and the application of heating blankets, but the effect is not ideal. Therefore, medical staff of the department of critical care medicine of the Second Affiliated Hospital of Anhui Medical University designed a heating device and temperature control system for CRRT dialysis fluid bag, and obtained the National Invention Patent of China (ZL 2021 1 0334906.7). The device includes a heating and thermal insulation device and a temperature control system, wherein the heating and thermal insulation device is composed of the body of the heating dialysis fluid bag and the temperature control structure, which solves the problems of safe and efficient liquid heating and thermal insulation during the CRRT process. The temperature control system can display the dynamic state of the patient's body temperature, adjust the temperature of the dialysis fluid bag in time, and monitor the temperature of the blood transfusion in real time through the cooperation of the five modules of data collection, data handle, data analysis, regulation and display. This design is applied to CRRT, which can achieve precise control of body temperature of critically ill patients, and has certain clinical significance.

Objective:To investigate the clinical effect of early bronchoalveolar lavage on patients with aspiration pneumonia.Methods:A retrospective study was conducted on 55 patients with aspiration pneumonia who met inclusion criteria but not exclusion criteria in the Intensive Care Department of our hospital from January 2020 to April 2021. The patients were divided into the control group (32 cases) and the bronchoscopic lavage group (23 cases) according to whether they received bronchoscopic lavage within 24 h after aspiration. Basic information (sex, age, body mass index, chest X-ray score, oxidation index, temperature, heart rate, respiratory rate, white blood cells, PCT, IL-6, CPR and APACHE Ⅱ score), etiology changes at the early stage (≤ 3 d) and later stage (4-7 d after admission), and changes in prognostic indexes (mechanical ventilation time, length of ICU stay, length of stay and mortality) were compared between the two groups. The clinical efficacy of early endoscopy lavage for aspiration pneumonia was evaluated.Results:The positive rate of early etiological culture was 85.2%, the bacterial positive rate was 72.9% and the fungal positive rate was 14.6%. Pseudomonas aeruginosa accounted for 20.8%, Klebsiella pneumoniae accounted for 14.6%, Staphylococcus aureus and Streptococcus accounted for 12.5%, and there was no significant difference in the distribution between the bronchoscopic lavage group and the control group (all P>0.05). The positive rate of late etiological culture was 88.6%, the bacterial positive rate was 85.7% and the fungal positive rate was 2.9%. The positive rate of late bacterial culture was significantly decreased in the bronchoscopic lavage group ( P < 0.05), and the other results were not significantly different from the control group (all P>0.05). After early bronchoscopic lavage, the duration of mechanical ventilation, length of ICU stay and length of stay were significantly shortened, and the fifth day CPIS score was significantly decreased (all P< 0.05). Conclusions:Early endotracheal lavage can reduce mechanical ventilation time, length of ICU stay and length of stay of aspiration pneumonia, and reduce the positive rate of bacterial culture in the lung at the later stage, which needs to be further verified by a large randomized controlled study.
