Objective To explore the effect of family mission intervention on family function and parental self-efficacy in children with malignant tumor. Methods 58 children with malignant tumor from 4 tertiary general hospitals in Tangshan city were included. Their parents were divided into control group (n=28) and intervention group (n=30). Both groups received routine treatment and nursing, while the intervention group received family mission intervention in addition. They were evaluated with Feetham Family Functioning Survey (FFFS) and the Self-Efficacy for Parenting Tasks Index-Toddler Scale (SEPTI) before and after intervention. Results After intervention, the total FFFS score (1.01±0.55), family and individual relationship score (0.79±0.64), and family and social relations score (1.21±0.92) were lower in the intervention group than in the control group (P<0.05). The scores of limit/constraint (4.19±0.55), game (4.09±0.32), and education (4.17± 0.78) of SEPTI were higher in the intervention group than in the control group (P<0.05). Conclusion Family mission intervention can improve the family function of children with malignant tumor, and improve the parents' self-efficacy.

Objective To discuss the surgical therapy of primary leiomyosarcoma of the inferior vena cava(PIVCLS).Methods Retrospective analysis of was made 5 patients of PIVCLS from Oct 2009 to May 2011 hospitalized in Department of Vascular Surgery,Provincial Hospital Affiliated to Shandong University.All patients underwent surgical resection,combined with reconstruction of bilateral renal vein and distal inferior vena cava using artificial vascular graft.Results Surgical resection was performed successfully in all patients.The mean operation time was 166.6 min,with mean blood loss 1 560 mL.Leiomyosarcoma intruding the inferior vena cava and right renal vein were observed in all patients during operation.The mean size was 12 cm × 10 cm× 8 cm.The diagnosis of PIVCLS in 5 patients was confirmed by postoperative pathologic examination.All patients did not present lower extremity swelling after surgery and discharged from hospital with normal blood (BUN) and (CREA).All patients were administrated with oral warfarin therapy after discharge.No clinical relapse and pulmonary embolism was observed during the follow-up (range 3 months to 12 months).The ultrasound revealed the patency of artificial vascular grafts in all patients.Conclusions Surgical resection combined with reconstruction of bilateral renal vein and distal inferior vena cava using artificial vascular graft is an effective and feasible treatment of PIVCLS.Leiomyosarcoma is completely eliminated and important abdominal viscera are protected well during the procedure because of minimal impact on hemodynamics.The incidence of postoperative pulmonary embolism also decreases obviously.

Objectives To understand the effect of intraperitoneal injection of naringenin,a SMAD3 inhibitor,on the skeletal muscle after acute contusion in a mouse model.Methods Seventy-two mice of 7-8 weeks old (20-24 g)were randomly divided into a control group,an acute contusion (B)group,an acute contusion+1％DMSO injection (C)group and an acute contusion+naringenin injection (D)group,each of 18.The acute contusion model was created by hitting the right tibialis anterior muscle in mice of all groups except the control group.Intraperitoneal injection of I％DMSO and naringenin were given to group C and D respectively every day until execution,while the 18 mice in the control group were fed without injury or injection.The time of injury was set as Day 0.After being fed for 28 days,all mice were executed and the right tibialis anterior was harvested.Western blotting was used to detect the difference of SMAD3,pSMAD3,Collagen Ⅰ,and α-SMA expression among the 3 groups.Hematoxylin-Eosin (HE)staining and Masson staining were used to detect the difference of pathological changes.Moreover,the appearance of fast twitch contraction and tetanic contraction were also documented to figure out the quality of the injured skeletal muscle.Results Compared with the control group,the SMAD3 and pSMAD3 level in injured skeletal muscle increased,but both were less in group D than group B and C.Similarly,the average level of Collagen Ⅰ and α-SMA in all three injury groups was higher than the control group,but the level of these indexes were lower in group D than that in group B and C.HE staining showed more mesenchyme in injury groups than the control group.Masson staining found the upregulation of fibrosis in injured muscles,with the area of fibrosis in group D significantly lower than group B and C.Compared with control,the injured skeletal muscle had significantly poorer fast twitch and tetanic contraction performance,with the condition of group D significantly better than group B and C.Conculsion The naringenin,a SMAD3 inhibitor,mitigates the phosphorylation of SMAD3 after acute contusion in a mouse model.The fibrosis and scar formation was alleviated,hence improving the healing of the injured skeletal muscles.

Objective:To evaluate the quality of the current foreign clinical practice guidelines (CPG) on obstetric venous thromboembolism (VTE), providing reference for standardizing the prevention and treatment of domestic VTE clinical practice.Methods:The GPGs for the management of obstetric VTE published abroad from inception to July 2020 were electronically searched. Two researchers independently evaluated the quality of the included guidelines in accordance with the internationally recognized guideline evaluation tool, AGREE Ⅱ.Results:A total of 12 guidelines, 2 recommendations and 1 consensus for obstetric VTE were included, covering 3 continents and 9 countries, and the published time span was 2009-2020. The standardized scores of the six domain (scope & purpose, stakeholder involvement, rigor of development, clarity of presentation, applicability and editorial independence) included in the guidelines were: 99.44%, 62.78%, 70.35%, 95.74%, 68.80% and 76.94% respectively, and the scores in each domain were ≥ 50.00%, indicating that the included CPGs were of good quality. Except for the domain scope & purpose, the ranges of the other five domains were ≥ 50.00%, suggesting that the quality of the CPGs differed significantly. Among the 15 included CPGs, 4 CPGs were level A (recommended), 11 CPGs were level B (recommended after being revised), and there was no CPG in level C (not recommended). The difference in the recommended content of obstetric VTE management mainly focused on the risk assessment, drug type, dosage and period.Conclusions:The overall quality of the CPGs for obstetric VTE management is high, while the quality of the CPGs varies greatly. In addition, there are differences in the recommended content of obstetric VTE management. More high-quality researches are required to provide evidence-based support for the improvement of the CPGs.

Objective To investigate the effects of silenced Racl on invasion and migration in LOVo cells.Methods The expression of Racl mRNA and protein in colorectal cancer cells(including LoVo SW480.SW620.SW1116,HT29)were detected by RT-PCR and Western blot,respectively.The changes of cytoskeleton were observed in LoVO cells after transfected with Racl-shRNA.then invasion and migration were recorded respectively in LoVo cells after transfected with Racl-N17 and Racl-L61.Results Racl mRNA and protein were overexpressed in all selected colorectal cancer cells.Deletion of Racl decreased the cross-linked actin network and pseudopodia,and inhibited the invasion and migration in LoVo cells.The migration experiment showed that the migrated cells were higher in Racl-shRNA[(75±5)cells].Racl-N17 [(93±5)cells]and Racl-L61[(267±7)cells]groups compared with control group[(214±8)cells,P＜0.01,＜O.01 and＜0.05,resprectively].The invasion experimental study revealed that the migrated cells were higher in Racl-shRNA[(35±5)cells],Racl-N17[(42±5)cells]and Racl-L61[(86±7)cells] groups compared with control group[(73±6)cells,P＜0.01,＜0.01 and＜0.05,resprectively].Condusion Deletoin of Racl can inhibit the invasion and migration in LDVo cells.

Objective To compare the outcomes of arthroscopic single-row and suture-bridge repair of medium-sized rotator cuff tears through clinical and MRI assessment.Methods Forty-five patients with medium-sized rotator cuff tears who underwent arthroscopic repair using single-row (SR,n=29) or suture-bridge (SB,n=26) technique between July 2014 to June 2015 in our hospital,were retrospectively enrolled in this study.All surgeries were performed by the same senior doctor.The functional outcomes were assessed using the rating scale of the University of California at Los Angeles (UCLA),American Shoulder and Elbow Surgeons shoulder index (ASES),Fudan University Shoulder Score (FUSS),visual analog pain scale score (VAS),and range of motion (ROM) before the operation and at the last follow-up.MRI examination was performed at the final follow-up.Results Finally 50 patients were followed up successfully,24 in SB group and 26 in SR group.There were no significant differences between the two groups in terms of age,sex,follow-up duration,and the affected side.Before the operation,no significant differences were observed between the 2 groups in all the measurements.After more than 1-year follow-up,significant improvement was found in all measurements for both groups,but without significant differences between them.MRI examination showed no re-tears in either group.According to the Sugaya's classification,there were more type Ⅰ patients in SB group than SR group (83.3％ vs 61.5％),but the difference was not significant.Conclusion Arthroscopic suture-bridge repairing of medium-sized rotator cuff tears results in safe and good early clinical outcomes.However,compared with the single-row technique,there was no significant advantage.Although the MRI examination showed a better result of rotator cuff healing in the early stage,its long-term outcomes need further studying.

Objective To discuss the diagnosis and surgical treatment for carotid body tumors (CBT). Methods Retrospective analysis was made on 16 cases of carotid body tumors hospitalized in Shandong Provincal Hospital from January 2003 to October 2010. All patients were diagnosed by digital subtraction angiography, including 3 case of Shamblin type Ⅰ,11 cases of Shamblin type Ⅱ and 2 cases of Shamblin type Ⅲ. Three cases of type Ⅰ and 3 cases of type Ⅱ underwent carotid body tumor resection. Three cases of type Ⅱ underwent carotid body tumor plus external carotid artery resection, 3 cases underwent carotid body tumor plus external carotid artery resection plus carotid artery repairment, 2 cases did carotid body tumor plus external carotid artery resection plus internal carotid artery reconstruction. One of type Ⅲ underwent carotid body tumor plus external carotid artery resection plus carotid artery repairment, and the other one underwent carotid body tumor plus external carotid artery resection plus internal carotid artery reconstruction. Results Diagnosis of CBT was confirmed by pathology in all cases. There was no postoperative death、hemiplegia and blindness. The cranial nerve injury was caused in 7 cases, accounting for 43. 75%. 13 cases ( 81. 25% ) were followed up for 2 to 76 months ( mean 42 months), no tumor recurrence and metastasis was found. Conclusions Digital subtraction angiography (DSA) is important in the diagnosis and therapy of carotid body tumor. Surgical treatment is the choice of therapy for carotid body tumors.

AIM: To clarify the role of new apoptosis-related gene, TF-1 cell apoptosis-related gene 19(TFAR19), in the pathogenesis of systemic lupus erythematosis (SLE) and the relationship between TFAR19 and SLE. METHODS: DNA Ladder detection, Western blotting, immunological fluorescence method, ELISA and so on were used to test if ultraviolet B(UVB) could induce HaCaT cell apoptosis and TFAR19 expression. RESULTS: HaCaT cell apoptosis could be detected after 24 hours of 30 mj/cm 2 UVB irradiation. Also, we found that in active SLE patients, the TFAR19 antibody was increased, but not significant compared to the normal control. CONCLUSION: TFAR 19 is involved in the process of UVB induced ketatinocyte line HaCaT apoptosis and SLE pathogenesis.

OBJECTIVETo explore the diagnostic value of MRI and SPECT in early postburn brain edema in severely burned dogs.

METHODSTwenty-six mongrel dogs were randomized into control (n = 6) and burned groups in which every 5 dogs were allotted to each of following time points: 6, 12, 18 and 24 postburn hours (PBHs). The dogs in burn groups were inflicted with 50% TBSA of III degree skin burn and were infused with 5% glucose solution after 6 PBHs, so that severe early postburn brain edema was produced. MRI and SPECT were employed to observe dynamically the brain of dogs in all groups. The results were collected and compared with one another.

RESULTSThe results indicated that with MRI brain morphological change of early brain edema could be shown as early as within 12 PBH and diffuse brain edema became more obvious with elapse of time. The changes might be difficult to be found by MRI when T(1)WISIR decreased below 10%. T(2)WI SIR increased by 8.29% at 24 PBH with blurred demarcation between the brain gray and white matters. There was diffused and progressive nuclide ((99)TCm-ECD) concentration in the brain tissue as shown by SPECT at 6 PBH. The radio-nuclide taking ratio increased significantly after 12 PBH, especially at 24 PBH (P < 0.01) when compared with that before burn.

CONCLUSIONCombined application of MRI and SPECT could evidently increase sensitivity and specificity in the diagnosis of early postburn brain edema.

Objective To analyse the prognosis of 117 newly diagnosed nasopharyngeal carcinoma (NPC) patients underwent intensity modulated radiotherapy (IMRT). Methods From Jan to Nov 2005, 117 NPC patients who were treated by IMRT were enrolled. There were 81 males and 36 females with a median age of 42 years (range 18-76 years). According to Chinese Fuzhou Staging system(1992), 11 cases were Stage I , 15 Stage Ⅱ, 54 Stage Ⅲ and 37 Stage ⅣA. IMRT was carried out with Peacock plan. The prescription dose to the gross target volume(GTVnx) of nasopharyngeal tumor was 68 Gy, that of positive neck lymph nodes (GTVnd) was 60-66 Gy, clinical target volume 1 (CTV1) was 60 Gy, and CTV2 was 54 Gy. Results After a median follow-up time of 48 months (range 10.5-59.5 months), the 3-and 5-year overall survival (OS) rates were 95.7 % and 89.7 %, the disease-free survival (DFS) rates were 91.5 % and 87.2%, and the local-regional control rates were 94.0 % and 91.5 %. Univariate analysis showed the KPS, stage, Fuzhou clinical stage, status of blood platelet before treatment and uric acid after treatment were correlated with OS rate. T stage was the only independent factor of prognosis in the COX stepwise regression model. Conclusion Radical IMRT significantly prolongs the survival of NPC patients. T stage is the only independent prognostic factor for NPC patients.
