Objective To explore the application effect of negative pressure sealing drainage combined with active factor dressing and flap transfer in Gustilo Ⅲ type tibiofibular fractures.Methods From March 2019 to March 2022,92 patients with Gustilo type Ⅲ tibiofibular fracture admitted to the Department of Orthopaedics of the Third People's Hospital of Zhangjiagang City were randomly divided into the experimental group(internal and external fixation+flap transfer+negative pressure sealing drainage+active factor dressing,n=46)and the control group(internal and external fixation+flap transfer+conventional dressing change+active factor dressing,n=46),and the clinical indexes,clinical efficacy,ankle joint function,lower limb function and complications were compared.Result The hospital stay time(25.32±8.36)d,the flap healing time(9.69±1.24)d,the fracture healing time(8.24±1.84)month and the wound healing time(14.24±3.84)d of the experimental group were shorter than those of the control group(43.44±11.84)d,(11.53±2.07)d and(9.12±2.50)month,(50.11±5.12)d(P＜0.05).The total effective rate of the experimental group(93.48％,43 cases/46 cases)was higher than that of the control group(71.74％,33 cases/46 cases,P＜0.05).The ankle pain scores of both groups after treatment were lower than before treatment,and the experimental group was lower than the control group,and the scores of ankle function and stability,the scores of American Association of Foot and Ankle Surgery(AOFAS)and the knee joint score of American Hospital for Special Surgery(HSS)after treatment were higher in both groups than before treatment,and the experimental group was higher than the control group(P＜0.05).The total complication rate of the experimental group(4.34％,2 cases/46 cases)was lower than that of the control group(17.39％,8 cases/46 cases,P＜0.05).Conclusion The application of negative pressure closed drainage combined with active factor dressing in Gustilo typeⅢ tibia and fibula fracture is effective,can promote postoperative wound recovery,improve ankle and lower limb function,and the incidence of complications is low.

OBJECTIVETo study the influence of processing on metabolism of the main component of bitter almond-amygdalin in rat.

METHODThe blood was collected at different times after amygdalin given by injection and oral, bitter almond and its processed production given by oral respectively, and then detected by both HPLC and HPLC-MS(n) methods after extraction pretreatment.

RESULTAfter injection, amygdalin was absorbed in prototype to blood rapidly, while the other three kinds of medicine given by oral were all not detected the prototype of amygdalin, but two metabolites were detected which were isomers of prunasin confirmed by mass spectrometry. The metabolic pathway of prunasin in processed bitter almond group was markedly different from the bitter almond group.

CONCLUSIONProcessing has a significant effect on bitter almond metabolic processes in rats.

Objective:To explore the effect of core muscle group training combined with balance cup therapy in patients with chronic nonspecific low back pain.Methods:From January 2017 to December 2019, convenience sampling method was used to select 130 patients with chronic nonspecific low back pain in Guangdong Province Foshan Hospital of Traditional Chinese Medicine. According to the random number table, patients were divided into core muscle group and combined treatment group, with 65 cases in each group. The core muscle group was given the Swiss ball to perform core muscle training in the order of sitting, double bridge, knee flexion double bridge, reverse bridge and push-ups. The combined treatment group was given a balance tank based on core muscle training, followed by flash tank, walking tank, and sitting tank treatment. After 4 weeks of intervention, we compared the scores of the Visual Analogue Scale (VAS) , Roland-Morris Disability Questionnaire (RMDQ) , Finger-Floor Distance (FFD) , and static and dynamic muscle endurance time, and the total effective rate of treatment between the two groups of patients.Results:After intervention, the scores of VAS, RMDQ and FFD of combined treatment group were lower than those of core muscle group, and the differences were statistically significant ( P<0.01) . The static and dynamic muscle endurance time of combined treatment group were higher than those of core muscle group, and the differences were statistically significant ( P<0.01) . The total effective rate of combined treatment group was 90.77% (59/65) , which was higher than 76.92% (50/65) of core muscle group, and the difference was also statistically significant ( P<0.05) . Conclusions:Core muscle training combined with balance cup therapy can reduce the degree of pain in patients with chronic nonspecific low back pain, improve waist dysfunction, waist flexibility and muscle endurance, and have good clinical effects.

Objective To compare the long-term survival outcomes of patients with T_1-2N₀M₀ duodenal neuroendocrine tumor (DNET) after endoscopic resection (ER) or surgical resection (SR). Methods Patients diagnosed with T_1-2N₀M₀ DNET between January 1, 2004, and December 31, 2015, were extracted from the SEER database. Kaplan-Meier survival curve and log-rank test were used to compare overall survival (OS) rate and cancer-specific survival (CSS) rate between patients undergoing ER or SR. Propensity score matching (PSM) was used to reduce grouping differences, and multivariate Cox regression was used to analyze factors affecting OS and CSS before and after PSM. Results A total of 656 patients were included, with 457 in ER group and 199 in SR group. Before PSM, there was no significant difference in the 5-year OS rate between the ER and SR groups (88.9% vs 89.6%), but there was a significant difference in the 5-year CSS rate (99.3% vs 96.9%, P＝0.017). Before PSM, multivariate Cox regression analysis showed advanced age was an independent risk factor for decreased OS (P＜0.001). After PSM, there was no significant difference between the ER group (n＝187) and SR group (n＝187) in 5-year OS rate (90.2% vs 88.9%) or CSS rate (98.9% vs 96.7%). After PSM, multivariate Cox regression also showed advanced age was an independent risk factor for decreased OS, while resection method was not an independent factor for OS or CSS. Conclusions There is no significant difference in OS or CSS after endoscopic treatment and surgical treatments for patients with T_1-2N₀M₀ DNET, and advanced age is an independent factor for OS.
