Left atrial appendage ( LAA) arises from the left atrial free wall. It is the remnant of the original embryonic LA, distinct from the rest of the left atrium. It has a unique anatomical structure, physiological function, hemodynamic characteristics. LAA has complex surrounding structures, great variability, and close relation with thrombosis. This paper reviews the morphological and functional characteristics of LAA. Familiar with adjacent relationship of LAA and correlation between LAA and thrombus formation has important clinical significance that can reduce the risk of postoperative complications in interventional procedures, the incidence of car?dioembolic stroke, the clinical misdiagnosis on LAA thrombosis.

Objective To evaluate effect of humanized nursing on psychological state of patients with chronic urticaria receiving autohemotherapy. Methods 58 cases with chronic urticaria in our hos-pital were randomly divided into the observation group and the control group with 29 cases in each group, the control group was treated with conventional care, the observation group received conventional care combined with humanized nursing. The anxiety, depression and satisfaction degree were compared for these two groups and the data went through χ2 test and t test. Results The score of self- rating anxiety scale (SAS) and serf-rating depression scale (SDS) of the observation group was significantly lower than that of the control group, the satisfaction rate of the observation group was significantly higher than that of the con-trol group. Conclusions Application of humanized nursing in patients with chronic urticaria receiving autohemotherapy can reduce their anxiety and depression and has pivotal significance on treatment of pa-tients with chronic urticaria.

[Objective]To study whether Cervus and Cucumis Polypeptide(CCP ,Lugua polypeptide) can treat osteoporosis or not. [Methods]Forty 4-month-old female SD rats were randomized into four groups(10 in each group) ,including SHAM,0VX, OVX+CCP1 and OVX+CCP2 groups. Male rats in OVX groups take the ovariectomized surgery. Since the 13th week, rats in groups A and B got 0.9% physiological saline injection once in a day, group C was treated with CCP 0.4mL/(kg·d)injection and group D treated with CCP0.8mL/(kg·d) injection once one day. Twelve weeks later, al rats were sacrificed for obtaining specimen. Took right femurs, measured the bone biomechanical properties. [Results ]After 12 weeks since injection, the biomechanical property of right femurs in group OVX was significantly lower than that of the SHAM group( P<0.01); parameters such as maximum load and elastic load in group OVX+CCP1 and OVX+CCP2 were higher than that of group OVX(P<0.05), but lower than that of group SHAM(P<0.05). The distinction of the above parameters was significant( P<0.05)between group OVX+CCP1 and OVX+CCP2. [Conclusion]1.CCP can significantly im-prove the bone internal biomechanical properties in ovariectomized(OVX) rats, so it has function to treat osteoporosis caused by drop in estrogen level. There are differences of bone biomechanical properties aspects when treated with different dosage of CCP, which shows the tendency of dose-dependent effect. So we can conclude that CCP may have dose-dependent effect.

Objective　To provide data support for the prevention and control of melioidosis by analyzing epidemiological characteristics of melioidosis bloodstream infection and antibiotic resistance of its pathogen in Hainan Province from 2012 to 2021. Methods Data was collected from Hainan Antimicrobial Resistance Surveillance System, and WHONET 5.6 software was used to merge and analyze data. Results The case numbers of melioidosis bloodstream infection showed an increasing trend year by year from 2012 to 2021. The ratio of male to female patients was 4.6∶1, with 347 cases (58.91%) of patients aged 40-<60, the age group with the highest incidence. The number of cases from July to November were 424 cases (72.0%). Haikou and Sanya reported the largest case number, with 261 and 116 cases respectively. But there were no case reported from central area including Chengmai, Tunchang, Qiongzhong and Baoting. Burkholderia pseudomallei strains were isolated from both blood and other specimens in 105 of the 589 patients, with respiratory tract and wood specimens being the sites with the highest number of strains isolated other than blood; the resistance rates of Burkholderia pseudomallei to five antibiotics showed no obvious trend of change, with the lowest resistance rate to imipenem among the five drugs at 0.6%, followed by ceftazidime at 2.2%. Conclusion During the typhoon season, elderly, middle-aged male in coastal areas should pay attention to avoid or reduce their contact with mud and water. For patients with melioidosis bloodstream infection, imipenem or ceftazidime should be selected as early as possible for initial treatment.

Objective To determine the levels of plasma histamine and oxidative status in patients with dermatographism before and after the treatment with anti-histamine drugs. Methods Totally, 85 patients with dermatographism were randomly divided into two groups to receive oral desloratadine and cetirizine respectively for 4 weeks. Enzyme linked immunosorbent assay (ELISA) was performed to detect the plasma level of histamine, superoxide dismutases (SOD), glutathion peroxidase (GSH-PX) and malondialdehyde (MDA) in all the patients before and after the treatment and in 15 normal human controls. The efficacy of desloratadine and cetirizine for dermatographism was estimated. Results The response rate was 83.72% and 78.57% in patients treated with desloratadine and those with cetirizine, respectively (x2 = 0.369, P> 0.05). The untreated patients with dermatographism showed an elevation in the plasma level of histamine (3.87 ± 1.21 ng/ml vs. 1.76 ± 0.56 ng/ml, P< 0.05) and MDA (3.86 ± 1.03 nmol/ml vs. 2.19 ± 0.82 nmol/ml, P< 0.05), but a decline in the activity of SOD (86.29 ± 19.9 U/ml vs. 112.12 ± 27.88 U/ml, P< 0.05) and GSH-PX (74.52 ± 47.67 vs.915.06 ± 115.96, P< 0.05) compared with the normal human controls. The treatment with antihistamine induced a reduction in the plasma level of histamine (1.61 ± 0.47 ng/ml vs. 3.87 ± 1.21 ng/ml, P< 0.05) and MDA (2.65 ± 0.77 nmol/ml vs. 3.86 ± 1.03 nmol/ml, P< 0.05), but an increment in the activity of GSH-PX (921.46 ± 157.37 vs.74.52 ± 47.67, P < 0.05) with no changes of SOD in patients with dermatographism. Conclusions In patients with dermatographism, plasma histamine is increased and there is an imbalance of oxidation-antioxidation.Desloratadine and cetirizine are effective for the treatment of dermatographism.
