ABSTRACT
Objective:To compare the clinical effectiveness of propeller flap and vascular chain flap based on dorsal cutaneous branch of proper palmar digital artery for repair of wounds of fingertip or finger-pulp.Methods:From April 2018 to May 2021, a total of 55 patients (55 fingers) with wounds of fingertip or finger-pulp in the 2nd-5th fingers were treated in emergency surgery in the Department of Hand Surgery, the Second Hospital of Tangshan. The patients were randomly divided into 2 groups by the method of drawing lots. The wounds of 29 patients (29 fingers) were repaired by propeller flaps based on dorsal cutaneous branch of proper palmar digital artery (propeller group) and that of 26 patients(26 fingers) were treated by vascular chain flaps based on dorsal cutaneous branch of proper palmar digital artery(vascular chain group). Survival of the flaps and the skin grafts at donor sites were observed between the 2 groups. The operation and follow-up time in both groups were recorded. Postoperative follow-up included outpatient clinic visits, telephone reviews and WeChat video-clips. At final follow-up, the static TPD of the flaps, patient satisfaction with the appearance of flaps and donor sites and the Range of motion(ROM) of the injured fingers were recorded. The measurement and count data of both groups were compared by independent sample t-test, χ2 tests or Fisher's exact test, respectively. P<0.05 was considered a statistically significant. Results:All the flaps and skin grafts survived primarily in both groups. The operation time in propeller group was 57.55 minutes±4.35 minutes. It was less than what in the vascular chain group (61.12 minutes±4.58 minutes) and with statistically significant difference( P<0.05). The follow-up period was 14.55 months±2.89 months in propeller group and 15.15 months±3.78 months in the vascular chain group. There was no significant difference between the 2 groups( P>0.05). At final follow-up, the static TPD and patient satisfaction with the appearance of flaps in propeller group were 6.55 mm±1.24 mm and 4.59±0.50, which were better than 7.46 mm±1.27 mm and 4.31±0.47 in the vascular chain group with a statistically significant difference( P<0.05). The patient satisfaction with the appearance of donor sites and ROM of the injured digital joints in propeller group were 4.45±0.57 and 190.86°±8.56°, while what in the vascular chain group were 4.35±0.56 and 185.96°±10.58°. There was no significant difference between the 2 groups( P>0.05). Conclusion:The propeller flap and vascular chain flap are both based on dorsal cutaneous branch of proper palmar digital artery and are both suitable for repair of wounds of fingertip or finger-pulp. Compared with the vascular chain flap, the propeller flap has the advantages in shorter operation time, better flap sensation and appearance.
ABSTRACT
Objective@#To explore the mediation mechanism of coronary artery lesion among both male and female Kawasaki disease (KD) children.@*Methods@#Children with KD that hospitalized in the Wenzhou Medical University affiliated Yuying Children’s Hospital from January 2009 to December 2014, were included in this study. Differences on demographical characteristics, clinical manifestations, laboratory indicators, regimen and time of treatment, results from pre/post echocardiography and treatment between male and female patients, were compared. The independent effect of gender on the risk of coronary artery lesions (CAL) was evaluated, and the mediating effect of BMI, visiting time and KD type on the association between gender and CAL were also studied.@*Results@#The average BMI level of male patients was higher than that of female patients. The difference was statistically significant (P<0.001). The prevalence of overweight among male patients (20.9%) was higher than female (14.1%). The difference was statistically significant (P=0.011). Data from the multivariate logistic regression analysis confirmed that the incidence of CAL in male patients was higher than that in female patients (aOR=1.50, 95%CI: 1.06-2.12) but the CAL was mainly different before on the immunoglobulin therapy. Results from the mediation analysis showed that BMI was an important mediator in the association between gender and CAL, with the indirect effect as 1.05 (95%CI: 1.01- 1.10) and the proportion mediated as 13.0%.@*Conclusions@#Male patients presented higher incidence of CAL but was mainly reflected in the difference of CAL before the treatment. BMI was probably an important mediator related to the association between gender and CAL.
ABSTRACT
Objective To determine the quercetin content in Folium A pocyni Veneti from different commercial markets and harvest time by HPLC .Methods The determination was performed on an Aglient Eclipse XDB-C18 column (250 mm × 4 .6 mm ,5 μm)at 30 ℃ with a mobile phase composed of Methanol :0 .1% phosphoric acid run at gradient elution ;the detec-tion wavelength was 360 nm .Results It is a better timing to harvest when the flower is turning fruit and the leaf color is turn-ing from green to yellow .Our results have demonstrated that at that time ,the content of quercetin in Folium A pocyni Veneti was relatively higher .In addition ,this report also shows that the concentration of quercetin in most medicinal materials from domestic market complies with the requirement of the Pharmacopoeia ,but there were still a small percent of samples that didn′t meet the Pharmacopoeia standards .Conclusion We suggested that the quality supervision and inspection on Folium A pocyni Veneti needs to be strengthened .
ABSTRACT
Objective To explore the pathological changes of lung, expression of the relevant inflammatory factors and oxidative stress markers of Sprague-Dawley (SD) rats undergoing autologous orthotopic liver transplantation (AOLT). Methods Thirty SD rats were randomized into sham group and AOLT group. The pathological changes of lung, expression of the relevant inflammatory mediators and oxidative stress markers were detected . Results ( 1 ) Compared with the sham group , the pathological scores of lung tissue in AOLT group increased significantly and reached its peak at 8 h after surgery. Then the pathological scores decreased to the level of sham within 24 h to 48 h after surgery; (2)The relative expression of inflammatory mediators including TNF-α, IL-1β, IL-6 and IL-8 increased significantly and reached its peak at 8 h after surgery in AOLT group. Then decreased to the level of sham group within 24 h to 48 h after surgery; (3)The change trends of MDA and H2O2 were similar to inflammatory mediators.The relative SOD expression decreased significantly and touched the nadir at 8h after surgery and then increased. Conclusion The pathological changes of lung expression, the relevant inflammatory mediators and oxidative stress markers of rats underwent AOLT were consistent.
ABSTRACT
Objective To analyze the effect of clomipramine combine sleep deprivation on depression rat behavior and hippocampal CA3 neuron apoptosis.Methods Chronic unpredictable mild stimulation was used to establish 40 depression model rats.They were randomly divided into depression group,clomipramine group (5 mg/kg orally),sleep deprivation group (36 h continuous full sleep deprivation),chlorpromazine combination of sleep deprivation group,and then selected 10 rats as control group.Open-field test and water maze test were used to test rats' behavioral change after 28 days intervention.RT-PCR,Western blot were used to detect the GDNF and Bcl-2 expression of hippocampal CA3 neurons.TUNEL assay was performed to test hippocampal CA3 neuron apoptosis ratios in each group.Results Open-field test level score,vertical score and latency of combination group were (75.6±7.3),(26.4±4.3),(1.1±0.2),and showed no significant difference with those of control group((79.4 ±6.8),(28.6±5.7),(1.0±0.4)) after 28 d intervention (P＞0.05),while the level score,vertical score were significantly higher than those in other three groups(P＜0.05),and the latency period was significantly lower than that in other three groups (P＜0.05).The combined group showed a trend of gradually shortened in water maze escape latency.GDNF,Bcl-2 expression of control group and combined group was significantly higher than those in other three groups (P＜0.05),while the difference between the two groups was not statistically significant (P＞0.05).Sleep deprivation group' apoptotic rate was the highest (55±6)％,significantly higher than the control group and the combination group ((14±3) ％ and (19±4)％).Conclusion Clomipramine combined sleep deprivation can improve the ability of rat model of depression and suppression of acts of hippocampal CA3 neuron apoptosis,and its effect may be related to increased hippocampal CA3 GDNF,Bcl-2 level.
