ABSTRACT

OBJECTIVE To evaluate the efficacy of the functional dressing of Polygonum capitatum nanofibers (P-PVP-PCL). METHODS P-PVP-PCL were prepared by electrospinning technology, and the microstructure of P-PVP-PCL was observed. The antibacterial activity and antioxidant activity of P-PVP-PCL and its effects on the survival rate, adhesion and migration rate of mouse fibroblast L929 cells were investigated. The effects of medical gauze dressing, blank nanofiber dressing (PVP-PCL) and P- PVP-PCL on the healing rate of the wound were investigated by establishing the back skin wound model of rats. The pathological changes of the wound tissue and collagen fiber deposition were observed, as well as the number of platelet endothelial cell adhesion molecule-1 (CD31) positive blood vessels and the expression of transforming growth factor-β (TGF-β) protein in wound tissue. RESULTS P-PVP-PCL had a smooth surface and a double-layer structure at the cross-section. The inhibition rates of P-PVP-PCL against Staphylococcus aureus and Escherichia coli were (98.88±0.66)% and (94.75±1.41)% , respectively. The antioxidant activity of P-PVP-PCL was (83.69±1.56)%, and the cell activity of the P-PVP-PCL group was significantly higher than those of the control group and PVP-PCL group (P<0.05). Compared with medical gauze dressings, P-PVP-PCL was more conducive to L929 cell adhesion; at 48 hours, the cell scratches in this group had basically healed. Compared with the medical gauze dressing group, the wound healing rates of the PVP-PCL group and the P-PVP-PCL group were significantly increased (P<0.05). On the 14th day of intervention, the wounds in the P-PVP-PCL group had basically healed, there was no dermal necrosis in the wound tissue, and the collagen fibers were arranged relatively neatly and the density was relatively uniform. The number of CD31 positive blood vessels and the expression of TGF-β protein showed a downward trend compared with the 7th day of intervention, and the number of CD31 positive blood vessels was significantly lower than those of the medical gauze dressing group and PVP-PCL group (P<0.05), but the protein expression of TGF- β was significantly higher than those of the medical gauze dressing group and the PVP-PCL group (P<0.05). CONCLUSIONS P-PVP-PCL has good antibacterial and antioxidant activity in E-mail:444096585@qq.com vitro, and can promote the proliferation, adhesion and migration of L929 cells. It can promote wound healing of rats in vivo.

ABSTRACT

Objective@#To explore how to select osteotomy line and its significance in mandibular distraction osteogenesis in infants and young children.@*Methods@#From May 2013 to July 2018, 208 infants and young children with mandibular deformity were admitted to the Department of Oral and Maxillofacial Surgery, Guangzhou Women and Children Medical Center, including 131 males and 77 females, with the age range of 8 days to 4 years, mean age of 6 months. Their clinical records were retrospectively analyzed. There were 162 cases of Robin sequence, 37 cases of the first and branchial arch anomalies, 2 cases of Treacher-Collins syndrome, and 7 cases of other congenital malformations. During the distraction osteogenesis, different osteotomy lines were selected according to the characteristics of the mandibular deformity: (1) For short mandibular body, the straight osteotomy line was used to extend the mandibular body. (2) For short mandibular ramus, a polygonal osteotomy line was used to extend the ramus. (3) For the increased mandibular angle, a curved osteotomy line was used to change the angulation.@*Results@#Linear osteotomy was used in 38 patients, polygonal line osteotomy were used in 129 patients, and curved osteotomy was performed in 41 patients. Among them, 4 patients with linear osteotomy had deciduous embryo injury, 6 patients with linear osteotomy and 2 patients with polygonal osteotomy had open occlusion, and patients with curved osteotomy did not have tooth and mandible damage, or malocclusion. All patients were followed up for 3 months to 5 years. The average follow-up time was 6.2 months. All osteotomy healed well, without osteonecrosis or nonunion.@*Conclusions@#For the mandibular distraction osteogenesis, osteotomy line could be individualized, according to the characteristics of mandibular deformity of infants and young children, which can reduce complications such as dental damage and open occlusion.

ABSTRACT

Objective To explore the Influence of different health education approaches to standard anticoagulation of non-valvular atrial fibrillation. Methods 400 patients with NVAF were randomly divided into the research group (n=200) and the control group (n=200). Baseline clinical information was recorded. Both groups were given regular education and treatment. The control group was randomly divided into two subgroups. One subgroup (patients or/and family members) was given knowledge lectures of atrial fibrillation, atrial fibrillation anticoagulant, and application of warfarin. The other was given the knowledge through booklets. Standard anticoagulation fulfillment rate, ischemic stroke, other events of artery embolism, major bleeding, minor bleeding and death in the two groups were observed after 1 year. The cost for different education approaches was also compared between the 2 subgroups. Results (1)In the research group, standard anticoagulation fullfillment rate (40.53%) was higher than that of the control group(15.96%) (P0.05).Other artery embolism rate , major bleeding, minor bleeding, death rate had no statistical difference. (2)Knowledge lecture group (10.8±1.0 min) spend more time than the booklet group (1.0±0.5 min) (P<0.01). The booklet group (5.1±1.1 yuan) costed more in terms of money than the knowledge lecture group (1.8±0.5 yuan) (P<0.01). (3)The knowledge lecture group showed higher standard anticoagulation fulfillment rate (47.96%) than that of booklet group (32.60%) (χ2=7.33, P<0.01). There was no statistical difference in ischemic stroke rate, other artery embolism rate, major bleeding rate, minor bleeding rate and the death rate. Conclusions Detailed, correct anticoagulant education and guidance can improve NVAF patients with standard anticoagulation, and reduce the risk of ischemic stroke.

ABSTRACT

This study was aimed to compare the effect of insulin plus rosiglitazone with that of insulin plus metformin on the level of serum N-terminal pro-brain natriuretic peptide (NT-BNP) in patients with type 2 diabetes mellitus, and to find out whether serum NT-BNP can be used as an index for predicting heart failure induced by rosiglitazone in the cases of type 2 diabetes mellitus. Sixty type 2 diabetic patients were recruited and were randomly divided into two groups: group A (n = 30) received insulin plus rosiglitazone (4 mg/d) and group B (n = 30) received insulin plus metformin. The observations covered an 8-weeks' course of treatment. Serum NT-BNP was measured at the beginning and at the end of 8 weeks. The Before-After study revealed that the level of serum NT-BNP did not change apparently in the two groups (P >0.05). There was no remarkable difference in the level of serum NT-BNP between the two groups (P>0.05). There were 3 cases with edema in the group of insulin plus rosiglitazone, but none with heart failure; in these three cases, the mean serum NT-BNP level at the end of the treatment exhibited an increase of 108.99 fmol/ml when compared with that at the beginning. Neither insulin plus rosiglitazone nor insulin plus metformin had apparent effect on the level of serum NT-BNP in the patients with type 2 diabetes mellitus. The question of whether serum NT-BNP is a predictive index of heart failure awaits answers given by more observation on type 2 diabetes mellitus patients using rosiglitazone.
