ObjectiveTo investigate the hemodynamic changes after multiple firearm injuries in a swine model. Methods Twelve pigs were divided into 2 groups randomly, with control group ( n =6) subjected to catheterization only. Multiple trauma group ( n =6) was subjected to tangential fracture of parietal bone and comminuted fractures of bilateral femora (ISS≥16) using 5 8 mm bullets. The hemodynamic changes, including MAP, PAP, PAWP, CO, SVRI and portal vein blood flow, were observed at different time intervals up to 72 h after trauma or catheterization. At the same time, gastric pHi was measured as well. Results Compared with control group pigs in multiple trauma group suffered a hyperdynamic circulation developed at 48~72 hours. The cardiac output rose and vascular resistance declined obviously. The pulmonary artery pressure and pulmonary capillary wedge pressure elevated significantly. Mean artery pressure, portal vein blood flow and gastric pHi declined significantly. Conclusion Without severe blood loss and hemorrhagic shock, the decrease of portal vein blood flow and viscera underperfusion still took place after multiple firearm injuries.

Objective Toexplore the expression and significance of microRNA-155 (miR-155) in psoriasis vulgaris. Methods Areal-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) method with TaqMan probe technology was performed to detect miR-155 expression in skin lesion area and nonskinlesionalarea of 35 patients with psoriasis vulgaris , compared with that of 30 normal controls. The correlations among miR-155 expression, psoriasis area and severity index (PASI) score and Interleukin-17A(IL-17A)expression were studied. Results The expressions of miR-155 and IL-17A in lesional and non-lesionalgroups were higher than that of control group (all P < 0.01). Also expressions in lesional skin were higher than non-lesional skin (both P < 0.01). In skin lesion group, significant positive correlations existed betweenmiR-155 or IL-17A expression and PASI score as well as miR-155 and IL-17A expression (all P < 0.05). Conclusions Up-expression of miR-155 was relevant to psoriasis development , which is related withthe hyperfunctionof Th17 cells in psoriasis.

Objective To explore the expression alteration and significance of inteleukin (IL)-37 in pso-riasis valguris (PV) patients. Methods Patients with PV had been treated with oral acitretin for 8 weeks. PASI score, ELISA and qRT-PCR were used to exam the data of 38 patients (PV group) and 32 controls (control group). Results IL-37 in PV group was significantly higher than that in control group (P < 0.001) and IL-37 changed slightly after 4 weeks of treatment(P > 0.05) but decreased obviously after 8 weeks(P < 0.001). Signif-icant correlations existed among PASI scores, IL-37, IFN-γ and IL-17, as well as among IL-37 and IFN-γ, IL-17 (P < 0.05). Conclusions The increase of IL-37 is relevant to PV development and is associated with pa-tients’ conditions, IFN-γ and IL-17 but the alteration of IL-37 is not related with IL-4.

Objective: To build up rabbit models of hepatic cirrhosis in through common bile duct partial ligation (CBDPL). Methods: Male New Zealand rabbits were subjected to CBDPL to induce hepatic cirrhosis. The liver biopsies were performed during the surgery and after sacrifice to evaluate hepatic fibrosis. The serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), total protein (TP) and albumin (ALB) were determined at week 0, 1, 2, 4 and 11 following the occlusion. Results: There were two kinds of morphological and histological manifestations after CBDPL, the one was inconspicuous hepatic fibrosis coexisted with sacculation-like bile ductal dilation and muddy stone; the other is remarkable hepatic fibrosis and cirrhosis along with uneven bile ductal dilation. The serum levels of ALT, AST, TBIL and DBIL were significantly higher after one week of operation. The levels of ALT, AST, TP and ALB decreased after two-week of operation, and the levels of TBIL and DBIL were returned to the normal level after two-week of operation. Conclusion: The animal models of hepatic cirrhosis can be built up through CBDPL in rabbits.

Objective:To understand the mental health status of fathers in neonatal intensive care unit and the intervention strategies for fathers′ mental health problems.Methods:Using the scoping review method as a framework, the studies on the mental health status of fathers with NICU in PubMed, CINAHL, Embase, Web of Science, Cochrane Library, PsycINFO, CNKI, WanFang Data, VIP and CBM were searched. The included studies were summarized and analyzed. The search time was from the database establishment to 30 August 2022. The content of literature extraction included author, country, publication time, research type, sample size, research variables, research content, and research results.Results:A total of twenty-five articles were included. Among them,11 literatures reported the mental health status of fathers of children in neonatal intensive care unit. Fathers experienced both negative and positive psychological changes after admission to the neonatal intensive care unit, including anxiety, depression, post-traumatic stress disorder, stress, sadness, and post-traumatic growth. Fourteen articles involved intervention strategies for mental health problems of fathers. Intervention strategies include enhancing social support (emotional support, peer support), stress management training (written disclosure, relaxation training, mindfulness therapy), information support, family integrated care (accompanied visits, kangaroo care).Conclusions:The admission of a newborn to the intensive care unit has caused many psychological problems for the father. However, there is still a lack of intervention strategies for fathers′ mental health problems, and it is still necessary for medical staff to take corresponding intervention measures according to fathers′ needs.

Objective:To preliminarily study the feasibility, safety and efficacy of transcatheter arterial chemoembolization (TACE) combined with selective portal vein embolization (SPVE) before surgical resection in the treatment of large liver cancer.Methods:A retrospective study was conducted on the clinical data of 17 patients with large liver cancer treated with TACE combined with SPVE from January 2016 to December 2019 at the Department of Hepatobiliary Surgery, the Sixth Medical Center of PLA General Hospital. The study included 15 males and 2 females, aged (59.17±10.30) years. The levels of alanine aminotransferase, tumor changes and patient survival were analyzed before operation, after TACE, and after SPVE.Results:Among the 17 patients, the levels of alanine aminotransferase on the 1st and 3rd day after SPVE was significantly higher than those after TACE [191.4 (30.5-1966.4) IU/L vs 125.3 (35.7-846.2) IU/L on the first day, and 298.5 (24.6-1334.2) IU/L vs 208.6 (21.6-775.6) IU/L on the 3rd day], all P<0.05. One month after the two combined embolism, among the 6 patients with a tumor diameter of 5-10 cm, 2 patients (33.3%) had complete remission, 3 patients (50.0%) had partial remission, and 1 patients (16.6%) had stable disease. For the tumor’s longest diameter, among the 11 patients with tumors >10 cm, 1 patient had complete remission (9.1%), 4 patients had partial remission (36.4%), 5 patients had stable diseases (45.5%), and 1 patient had disease progression (9.1%). Eventually, 11 patients underwent surgical exploration. The median residual liver volume before treatment was 329.5 (284.9-365.7) ml, and after the combined procedure 415.6 (354.7-718.8) ml. The median hyperplasia ratio was 28.1% (14.1%-51.3%). Eight patients finally underwent surgical resection. There was no death in the perioperative periods. The median tumor-free survival time was 17 (7-42) months, and the median survival time was 27 (7-42) months. Conclusion:For patients with large liver cancer with insufficient remnant liver volume, preoperative TACE+ SPVE has certain value in controlling tumor progression, promoting remnant liver hyperplasia, increasing surgical resection rate and improving prognosis.

Objective To explore the effect of medical and nursing integration notification on the truth knowing rate,anxiety,depression and quality of life in cancer patients undergoing chemotherapy. Meth-ods From February to March 2017,34 patients for the first time needing chemotherapy were included as control group,using normal disclosure.From June to July 2017,35 cases for the first time needing chemother-apy were included as the experimental group. The experimental group was informed of the medical and nurs-ing integration notification. The truth knowing rate,anxiety,depression and quality of life were compared be-fore and after three cycles of chemotherapy. Results After three cycles of chemotherapy,the truth knowing rate of patients in the experimental group (completely 57.14%,partly 34.29% and none 8.57%) was signifi-cantly different with the control group (completely 29.42%,partly 35.29% and none 35.29%,P<0.01). The scores of anxiety and depression in the experimental group(39.43±4.60,41.86±5.23) were significantly low-er than those before chemotherapy(42.37±4.76,45.69±5.49,P<0.01). The scores of anxiety and depression in the control group (45.74±5.20,49.74±5.42) were significantly higher than those before chemotherapy (42.77±5.62,45.56±6.27,P<0.01).After three cycles of chemotherapy,the scores of anxiety and depression in the experimental group were lower than the control group (P<0.01). After three cycles of chemotherapy, the total health status,body function,role function,emotional function,cognitive function,social function,fa-tigue,nausea and vomiting,and loss of appetite were statistically significant between the experimental group and control group (P<0.05). Conclusion The medical and nursing integration notification has a positive effect on the truth knowing rate,anxiety,depression and quality of life in cancer patients undergoing chemo-therapy.

Objective To investigate the clinical value of abnormal course of fetal superior mesenteric arteries (SMA) detected by ultrasound during the first trimester (11-13+6 weeks) in predicting congenital diaphragmatic hernia (CDH). Methods This study enrolled women who underwent fetal nuchal translucency (NT) screening during the first trimester in Central Hospital of Panyu District from March to December 2017. Low-speed high-definition flow imaging was used to observe the course of fetal SMA, and it was regarded as abnormal when the angle between SMA and abdominal aorta >90°. Once abnormal course of the SMA was suspected, the position of fetal thoracic cavity and abdominal organs would be scanned carefully. Furthermore, ultrasound examinations would be repeated at 16-18, 20-24, 28-32 and 37-40 weeks of gestation. Fetus diagnosed as CDH by ultrasound would be scheduled for MRI or autopsy to confirm the diagnosis. Pregnancy outcomes of all cases were followed up by telephone. Descriptive statistical analysis was used in this study. Results A total of 6 899 gravidas (6 964 fetuses) underwent NT scan during the first trimester were enrolled and the SMA of all fetuses were successfully displayed. Three cases with abnormal course of the SMA were identified. Two of them were diagnosed with left CDH at 17+ and 23+ weeks of gestation, which was confirmed by autopsy after termination of pregnancy, and the other one terminated pregnancy in first trimester due to a large omphalocele. Among the 6 961 fetuses with normal SMA, the pregnancy outcomes of 6 120 were successfully followed up, only one of which was found to have left CDH at 32 gestational weeks by ultrasound examination, and was later confirmed by neonatal MRI after delivery. No other fetal CDH was detected. Conclusions Abnormal course of the SMA identified in early pregnancy may be a simple and effective indicator for CDH that allow early intervention and treatment.
