Objective:To compare clinical effectiveness of the ulnar flap of dorsal cutaneous branch of proper palmar digital artery (PPDA) of little finger and the perforator flap of the 4th dorsal metacarpal artery (DMA) for reconstruction of small and medium-sized defects of ulnar palm.Methods:A retrospective case-control study method was employed in this study. From March 2017 to February 2024, a total of 42 patients of small and medium-sized defects of ulnar palm were treated in the Department of Hand Surgery, the Second Hospital of Tangshan. Twenty-four defects were reconstructed by the ulnar flaps of dorsal cutaneous branch of PPDA (PPDA group) of little finger and the rest of 18 defects were reconstructed by the perforator flap of the 4th DMA (DMA group). Sizes of the defects and flaps in PPDA group were 1.5 cm×1.2 cm-5.2 cm×2.3 cm and 1.6 cm×1.3 cm-6.0 cm×2.5 cm, respectively. Dimensions of the defects and flaps in DMA group ranged from 1.7 cm×1.2 cm-5.0 cm×2.4 cm and 2.0 cm×1.5 cm-6.2 cm×2.7 cm, respectively. Donor sites in both groups were all directly closed. Survival of the flaps and wound healing of donor sites were observed between the 2 groups after surgery. And the surgical time, intraoperative blood loss and duration of follow-up of the 2 groups were recorded. Postoperative follow-up included outpatient clinic visits, telephone interviews and WeChat video-clips. Static two-point discrimination (TPD) of the flaps were measured, and appearance of flaps and donor sites were evaluated based on the Michigan Hand Function Questionnaire (MHQ) evaluation criteria and Vancouver Scar Scale (VSS), respectively. The measurement and count data acquired from both groups were compared by independent sample t-test and χ2 tests or Fisher's exact test, respectively. P<0.05 was considered statistically significant. Results:All 24 flaps in PPDA group and 14 flaps in DMA group survived primarily, except 4 flaps in DMA group that had blisters and healed by dressing changes. Primary survival rate of the flaps in PPDA group (100%) was higher than that of DMA group (78%), and the difference was statistically significant ( P<0.05). Donor site incisions in both groups all healed primarily. The surgery time, intraoperative blood loss and duration of follow-up in PPDA and DMA groups were 64.50 min±7.70 min, 87.08 ml±25.11 ml, 15.46 months±3.83 months, and 62.44 min±8.28 min, 91.67 ml±27.28 ml, 16.39 months±3.24 months, respectively, and of which there was no statistically significant difference between the 2 groups ( P>0.05). At the final follow-up, static TPD and MHQ scores for flap appearance in PPDA group were 13.71 mm±2.91 mm and 4.63±0.50, which were better than 15.78 mm±2.78 mm and 4.28±0.46 in DMA group with a statistically significant difference ( P<0.05). VSS scores of donor site appearance in PPDA and DMA groups were (3.38±0.97 and 3.89±1.02, respectively. Although there was no statistically significant difference between the 2 groups ( P>0.05), the donor sites in PPDA group were more concealed and easier accepted by patients. Conclusion:The ulnar flap of dorsal cutaneous branch of PPDA of little finger and the perforator flap of the 4th DMA are both suitable for reconstruction of small and medium-sized defects of ulnar palm. Compared with the perforator flap of the 4th DMA, the ulnar flap of dorsal cutaneous branch of PPDA of little finger has advantages in higher primary survival rate, better flap sensation and appearance with more concealed donor site.

OBJECTIVE: To observe the effect of electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) on hippocampal neuronal ferritinophagy mediated by the nuclear receptor coactivator 4 (NCOA4)/ferritin heavy chain 1 (FTH1) signaling pathway in vascular dementia (VD) rats, and to explore the potential mechanisms of electroacupuncture for VD. METHODS: A total of 60 male rats of SPF grade were randomly divided into a blank group (12 rats), a sham surgery group (12 rats) and a modeling group (36 rats). In the modeling group, the modified 4-vessel occlusion method was used to establish the VD model. The 24 successfully modeled rats were randomly divided into a model group and an electroacupuncture group, with 12 rats in each group. In the electroacupuncture group, electroacupuncture was applied at left and right "Sishencong" (EX-HN1), and bilateral "Fengchi" (GB20), with continuous wave, in frequency of 2 Hz and current intensity of 1 mA, 30 min a time, once daily for 21 consecutive days. The learning and memory abilities were assessed using the Morris water maze test before modeling, after modeling and after intervention, as well as the novel object recognition test after intervention. After intervention, the neuronal morphology in the hippocampus was observed by Nissl staining; the iron deposition was observed by Prussian blue staining; the reactive oxygen species (ROS) level was detected by dihydroethidium (DHE) fluorescence staining; the levels of iron, malondialdehyde (MDA) and superoxide dismutase (SOD) in the hippocampal tissue were measured by the colorimetric assay, TBA method, and WST-1 method, respectively; the positive expression of NCOA4, FTH1 and glutathione peroxidase 4 (GPX4) was detected by immunohistochemistry; the protein expression of NCOA4, FTH1, GPX4, and the ratio of microtubule-associated protein 1 light chain 3B (LC3B) Ⅱ/Ⅰ in the hippocampus were detected by Western blot. RESULTS: Compared with the sham surgery group, in the model group, the escape latency was prolonged, and the number of platform crossings reduced (P<0.01), the recognition index (RI) was decreased (P<0.01); the hippocampal neurons displayed a blurred laminar structure, disorganized cellular arrangement, and the number of Nissl bodies was decreased (P<0.01); the percentage of iron deposition area in the hippocampus was increased (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were increased (P<0.01), the SOD level, and the protein expression of FTH1 and GPX4 were decreased (P<0.01). Compared with the model group, in the electroacupuncture group, the escape latency was shortened and the number of platform crossings was increased (P<0.01), the RI was increased (P<0.01); the hippocampal neurons exhibited more regular morphology, better-organized cellular structure, and the number of Nissl bodies was increased (P<0.05); the percentage of iron deposition area in the hippocampus reduced (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were decreased (P<0.01, P<0.05), the SOD level, and the protein expression of FTH1 and GPX4 were increased (P<0.01). CONCLUSION Electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) can improve learning and memory abilities in VD rats, and its mechanism may be associated with the regulation of the hippocampal NCOA4/FTH1 signaling pathway, inhibition of ferritinophagy, and alleviation of oxidative stress damage.

OBJECTIVE: To explore the mechanism of electroacupuncture (EA) at "Fengchi" (GB 20) and "Sishencong" (EX-HN 1) on learning and memory impairment in vascular dementia (VD) rats by observing the influences on the N-methyl-D-aspartate receptor (NMDAR)/cyclic adenosine monophosphate response element-binding protein (CREB)/brain-derived neurotrophic factor (BDNF) signaling pathway and the excitotoxicity induced by hippocampal calcium overload. METHODS: Thirty-two male SD rats of SPF grade were selected and randomized into a normal group (6 rats), a sham-operation group (6 rats) and an operation group (20 rats). VD model was established with the modified Pulsinelli's four-vessel occlusion (4-VO) method. Twelve rats after successfully modeled were assigned randomly into a model group and an EA group, 6 rats in each one. In the EA group, EA was delivered at bilateral "Fengchi" (GB 20) and "Sishencong" (EX-HN 1), with the continuous wave, the frequency of 2 Hz and the electric current of 1 mA. Stimulation intensity was adjusted depending on the slightly trembling of rat head. EA was given once daily, 30 min each time; and EA intervention was delivered for 21 days continuously. Using Morris water maze test, the learning and memory function was assessed. The neuronal morphology in the hippocampal CA1 was observed with HE staining; the level of glutamate (GLU) in serum and hippocampal tissue, as well as the activity of calcium pump (Ca²⁺-ATP) in the hippocampus were detected using colorimetric method. The protein expression of NMDAR, calmodulin-dependent protein kinase Ⅱ (CaMKⅡ), phosphorylated calmodulin-dependent protein kinase Ⅱ (p-CaMKⅡ), phosphorylated cyclic phosphoradenosine effector element binding proteins (p-CREB), CREB, and BDNF in the hippocampal CA1 was detected using immunohistochemistry. The protein expression of NMDAR, CREB, p-CREB and BDNF in the hippocampal tissue was detected using Western blot method. RESULTS: Compared to the sham-operation group, in the model group, the escape latency was prolonged and the platform crossing times of rats were reduced (P<0.01), the hippocampal neuron structure was damaged to different degrees, the structure in hippocampal CA1 was loosened, the arrangement disorganized, with clear grid-like structure; the neuronal morphology was irregular, pyknosis and even dissolution occurred, glial cells increased, blood capillary was dilated and the inflammatory cells were infiltrated and scattered. The level of GLU in the serum and hippocampal tissue and the protein expression of hippocampal NMDAR were elevated (P<0.01), the activity of Ca²⁺-ATP and the protein expression of CaMKⅡ, p-CaMKⅡ, CREB, p-CREB and BDNF were reduced (P<0.01, P<0.05); and the ratio of p-CaMKⅡ/CaMKⅡ and that of p-CREB/CREB were dropped (P<0.05). In comparison with the model group, in the EA group, the escape latency was shortened and the platform crossing times of rats rose (P<0.01), the arrangement was improved in the hippocampal CA1, the neuronal morphology was intact, the nucleoli were clear relatively and the pyknosis or dissolution were attenuated, the numbers of glial cells reduced relatively, the dilation of blood capillary was alleviated. The level of GLU in the serum and hippocampal tissue and the protein expression of NMDAR were reduced in the hippocampal tissue (P<0.01), the activity of Ca²⁺-ATP and the protein expression of CaMKⅡ, p-CaMKⅡ, CREB, p-CREB and BDNF were elevated (P<0.05, P<0.01); and the ratio of p-CaMKⅡ/CaMKⅡ and that of p-CREB/CREB increased (P<0.05). CONCLUSION EA at "Fengchi" (GB 20) and "Sishencong" (EX-HN 1) can attenuate learning and memory impairment in VD rats, which may be obtained by reducing GLU level in hippocampal tissue, inhibiting hippocampal excitotoxicity, mediating protein expression related to the NMDAR/CREB/BDNF signaling pathway, and maintaining neuronal survival and growth.

Objective:To investigate the association between dietary intake and physical activity category and their combined effects on all-cause and cause-specific mortality risk in patients with type 2 diabetes mellitus (T2DM).Methods:Between December 2013 and December 2021, a prospective cohort study was conducted on 19 863 T2DM patients in Changshu City, Qingjiangpu District (formerly Qinghe District), and Huai'an District, included in the national basic health service management. Information on deaths and underlying causes of death was obtained from the Jiangsu Provincial CDC and Prevention Death Surveillance System. Cox proportional hazards models were used to estimate the intensity of associations between dietary intake, physical activity, and their combined effects with all-cause and cause-specific mortality in patients with T2DM.Results:As of December 31, 2021, the research subjects had been followed up for 150 283 person-years, with a median follow-up time of 8.15 years. During the follow-up period, 3 293 people died, including 1 124 deaths from cardiovascular disease (CVD) and 875 deaths from cancer. Cox regression analysis showed that compared with the population of 0-1 recommended food group, those having more than five recommended food groups had a 19% lower risk of all-cause mortality [hazard ratio ( HR)=0.81, 95% CI: 0.70-0.94] and a 33% lower risk of all-cause mortality ( HR=0.67, 95% CI: 0.52-0.87). Compared with the T2DM population in the physical activity Q1 group, the risk of all-cause mortality, CVD mortality, and cancer mortality among the physical activity Q4 group reduced by 50% ( HR=0.50, 95% CI: 0.45-0.56), 50% ( HR=0.50, 95% CI: 0.41-0.61), and 27% ( HR=0.73, 95% CI: 0.60-0.88), respectively. The combined effect showed that compared with the population in the intake of food categories 0-2 and low physical activity groups, the risk of all-cause, CVD mortality, and cancer mortality in the intake of food categories 4-9 and high physical activity groups reduced by 55% ( HR=0.45, 95% CI: 0.38-0.53), 56% ( HR=0.44, 95% CI: 0.32-0.59), and 40% ( HR=0.60, 95% CI: 0.44-0.82), respectively. Conclusion:Type of dietary intake, physical activity, and their combined effects are associated with a reduced mortality risk in patients with T2DM.
