This study was aimed to select the best microwave extraction craft conditions of polysaccharide from Radix platycodonis. The composite scores of polysaccharide content and yield rate were used as evaluation indexes. By ex-amining the impact of microwave power, microwave time, extraction times and solid-liquid ratio on crafts, the best craft conditions were optimized by orthogonal test. The orthogonal test showed that when the microwave power was 1800 W, microwave time was 8 min, extraction times were 3, solid-liquid ratio was 1:15, the composite scores were the highest and the extraction craft conditions were the best. It was concluded that the crafts are efficient and stable. It had laid a foundation for the further study on polysaccharide from R adix p latyc odonis .

This study is to investigate protective effect of safflor yellow B (SYB) against vascular endothelial cells (VECs) injury induced by angiotensin-II (Ang-II). VECs were cultured and divided into six groups: control group, Ang-II group, Ang-II + SYB (1 micromolL(-1)) group, Ang-II + SYB (10 micromolL(-1)) group, Ang-II + SYB (100 micromolL(-1)) group and Ang- II + verapamil (10 micromolL(-1)) group. Except control group, all of VECs in other groups were treated with Ang- II at the final concentration of 0.1 micromolL(-1). Mitochondria membrane potential (MMP) and free calcium concentration ([Ca2+]i) were measured by laser scanning confocal microscopy, and mitochondria complex IV activity was detected by BCA method. The levels of reactive oxygen species (ROS) in VECs were analyzed by fluorescence detector and apoptosis of VECs was observed by flow cytometer. Caspase 3 was determined by Western blotting method. Comparing with control group, Ang-II was able to increase [Ca2+]i and ROS level, decrease MMP level, inhibit complex IV activity and enhance caspase 3 activity in VECs, as a result, enhance apoptosis of VECs. But SYB could significantly reduce the result induced by Ang- II relying on different dosages (P < 0.05 or P < 0.01). SYB was able to eliminate the effect of Ang-II on VECs via regulating [Ca2+]i, mitochondrial structure and function and inhibiting apoptosis.

ObjectiveTo investigate related factors for severe acute pancreatitis (SAP) with sepsis. MethodsA retrospective analysis was performed for the clinical data of 178 SAP patients who were admitted from January 2007 to March 2020, and according to the presence or absence of sepsis, they were divided into sepsis group with 56 patients and non-sepsis group with 122 patients. The t-test was used for comparison of continuous data between the two groups, and the chi-square test was used for comparison of categorical data between the two groups. A logistic regression model was used for multivariate analyses. ResultsThe incidence rate of sepsis was 31.46% in SAP patients. The univariate analysis showed that there were significant differences between the patients without sepsis and those with sepsis in APACHEⅡ score, blood glucose, blood calcium, serum total cholesterol, serum triglyceride, blood urea nitrogen, serum creatinine, serum albumin, admission to the intensive care unit, hypoxemia, deep venous catheterization, mechanical ventilation, surgical procedure, blood purification, indwelling urinary catheterization, and extent of pancreatic necrosis (all P<0.05). The multivariate analysis showed that APACHEⅡ score (odds ratio [OR]=6.748, 95% confidence interval [CI]: 2.191-20.788, P<0.05), hypoxemia (OR=3.383, 95% CI: 1.112-10.293, P<0.05), blood glucose (OR=5.288, 95%CI: 1.176-23.781, P<0.05), extent of pancreatic necrosis (OR=5.523, 95%CI: 1.575-19.360, P<0.05), and serum creatinine (OR=5.012, 95%CI: 1.345-18.762, P<0.05) were independent risk factors for infectious SAP with sepsis, while laparoscopic removal of focal necrotic tissue (OR=0.250, 95%CI: 0.066-0951, P<0.05) was an independent protective factor against SAP with sepsis. ConclusionThere are several important measures to reduce SAP with sepsis, including blood glucose control, protection of the functions of important organs such as lungs and kidneys, application of minimally invasive surgery to remove focal necrotic tissue, and emphasis on the treatment of critically ill patients with a high degree of pancreatic necrosis.

OBJECTIVEThe relationship between occlusion and temporomandibular disorders (TMD) remains disputed. The related epidemiological studies have been carried out focused on the occlusal characteristics in motion, for example in protrusion, retrusion or laterally extension and on some of malocclusion features. Very few studies were carried out on the intercuspal occlusion which is the most important occlusal relationship. Angle's classification of occlusion and the relationship of over-jet and over-bite are two prominent features now generally used in clinical practice for occlusal evaluation. In present study two kinds of features of occlusion were compared among TMD patients, malocclusion patients and university student volunteers, who of the laters represented nature population.
METHODS100 continued cases visiting our TMD Clinic during the year of 2 000 with complain of TMD problem, 100 malocclusion patients in continued orthodontic department records, and 268 university student volunteers were included. All subjects were with complete dentitions, except of age-related third or second molar tooth eruption difference. Study cast were obtained for all 468 subjects involved and following characters were studied. 1. Angle's classification; 2. Over-jet and over-bite relationship. Anteriorly it included cross-bite, cusp-to cusp bite, deep over-bite (without deep over-jet), deep over-jet (with or without deep-bite), open bite, and others. Posteriorly it included cross-bite, reverse cross-bite and others. 3. Abnormal occlusal index: For the purpose of quantitatively comparing the abnormal occlusal relationship of over-bite and over-jet, the occlusal index was introduced. The anterior continued abnormal was scored as 3 while posterior continued oclcusal abnormal scored as 5. The sum of the scores in the same subject was taken as his abnormal occlusion index.
RESULTS1. Ratio of Angle's I patients in malocclusion group was significantly lower than those in TMD group and US group (P < 0.05), while the later two groups had no difference (P > 0.05). 2. The ratios of anterior cross-bite and deep over-jet were higher in malocclusion group than those in other two groups. No significant difference for the other kinds of abnormal over-jet and over-bite relationship were found among the three groups. 3. The abnormal occlusion index of malocclusion group was higher than that of US group, but not than that of TMD group which had no difference with US group either.
CONCLUSIONS1. Aesthetic related anterior abnormal occlusion such as anterior cross-bite and deep-over-jet attract more attention of popular. But they had no relationship with TMD. 2. TMD patients had not significant occlusal features on Angle's classification and over-jet and over-bite relationship compared to malocclusion and nature population subjects.
