ABSTRACT

OBJECTIVE@#To investigate the effectiveness of tibial transverse transport (TTT) combined with modified neurolysis in treatment of diabetic foot ulcer (DFU) through a prospective randomized controlled study.@*METHODS@#The patients with DFU and diabetic peripheral neuropathy, who were admitted between February 2020 and February 2022, were selected as the research objects, of which 31 cases met the selection criteria and were included in the study. The patients were divided into two groups by random number table method. The 15 patients in the trial group were treated with TTT combined with modified neurolysis, and the 16 patients in the control group received treatment with TTT alone. There was no significant difference in gender, age, duration of DFU, ulcer area, Wagner classification, as well as preoperative foot skin temperature, visual analogue scale (VAS) score, ankle-brachial index (ABI), motor nerve conduction velocity (MNCV) of the common peroneal nerve, MNCV of the tibial nerve, MNCV of the deep peroneal nerve, two-point discrimination (2-PD) of heel, and cross-sectional area (CSA) of the common peroneal nerve between the two groups ( P>0.05). The time for ulcer healing, foot skin temperature, VAS scores, ABI, 2-PD of heel, and CSA of the common peroneal nerve before operation and at 6 and 12 months after operation were recorded and compared between groups. The differences in MNCV of the common peroneal nerve, MNCV of the tibial nerve, and MNCV of the deep peroneal nerve between pre-operation and 12 months after operation were calculated.@*RESULTS@#All patients in both groups were followed up 12-24 months (mean, 13.9 months). The surgical incisions in both groups healed by first intention and no needle tract infections occurred during the bone transport phase. Ulcer wounds in both groups healed successfully, and there was no significant difference in the healing time ( P>0.05). During the follow-up, there was no ulcer recurrences. At 12 months after operation, the MNCV of the common peroneal nerve, the MNCV of the tibial nerve, and the MNCV of the deep peroneal nerve in both groups accelerated when compared to preoperative values ( P<0.05). Furthermore, the trial group exhibited a greater acceleration in MNCV compared to the control group, and the difference was significant ( P<0.05). The foot skin temperature, VAS score, ABI, 2-PD of heel, and CSA of the common peroneal nerve at 6 and 12 months after operation significantly improved when compared with those before operation in both groups ( P<0.05). The 2-PD gradually improved over time, showing significant difference ( P<0.05). The 2-PD of heel and VAS score of the trial group were superior to the control group, and the differences were significant ( P<0.05). There was no significant difference in ABI, foot skin temperature, and CSA of the common peroneal nerve between groups after operation ( P>0.05).@*CONCLUSION@#Compared with TTT alone, the TTT combined with modified neurolysis for DFU can simultaneously solve both microcirculatory disorders and nerve compression, improve the quality of nerve function recovery, and enhance the patient's quality of life.

ABSTRACT

Objective:To compare the effect on scar in donor area of small-and medium-sized anterolateral thigh perforator flap(ALTPF) harvested from superficial and deep layer of the superficial fascia.Methods:A retrospective analysis was performed on 31 patients who had small-and medium-sized soft tissue defects in the extremities and admitted to the Department of Burns and Plastic Surgery of the Affiliated Hospital of Zunyi Medical University from January 2020 to February 2021. All the patients were repaired with ALTPFs. The sizes of defect ranged from 5.0 cm×3.5 cm to 17.0 cm×6.0 cm, and the flaps sized from 6.0 cm×4.0 cm to 20.0 cm×6.0 cm. Fifteen ALTPFs were harvested from superficial layer of superficial fascia (modified group), and 16 harvested from deep layer of superficial fascia (traditional group). The flap donor sites were sutured directly using the "Zunyi suture method". Appearance of scars was assessed within the Vancouver Scar Scale (VSS) and in addition the width of scars was been recorded. The data of the 2 groups were statistically analyzed. There was statistically significant difference when P<0.05. Results:All flaps were successfully viable. All wounds healed in Ⅰ stage and donor incisions healed in Ⅰ stage at 2-3 weeks after the surgery. All patients entered postoperative follow-up for 6 to 26 months, with a mean of 10.7 months. There was no ischaemic necrosis at the donor margin. There was no significant difference between circumference of thighs between the modified group and traditional group [ (0.10±0.40) cm and (0.03±0.39) cm, respectively]( P>0.05). VSS were found lower in the modified group (2.00±1.46) than that in the traditional group (3.06±1.61)( t=2.132, P=0.039), as well as the scars were found smaller at the widest point[(6.67±3.85) cm and(16.06±6.63) cm, respectively. t=2.807, P=0.005]. The differences were statistically significant( P<0.05). Conclusion:Small-and medium-sized ALTPFs, harvested in the superficial layer of superficial fascia, can reduce the width of the donor scar, improve the surgical outcome and increase patient satisfaction.

ABSTRACT

Objective To explore the effect of budesonide suspension for inhalation in the treatment of childhood asthma and its influence on growth and development in 1-2 years. Methods The 68 children with asthma admitted to our hospital from October 2016 to January 2017 were selected. Every patient had acute attacks and received continued medication. 34 patients treated with salbutamol sulfate inhaled aerosol were used as the control group. 34 patients treated with budesonide suspension combined with salbutamol sulfate aerosol were classified as the observation group. The interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), high-sensitivity-C-reactive protein (hs-CRP), maximum respiratory flow, IS maximum expiratory volume, regulatory B cell ratio, wheezing disappearance time, shortness of breath relief time, wet rales disappearing time, cough disappearing time, and the two year follow-up indicators of growth and development were compared. Results After medication, IL-6, TNF-α, hs-CRP, regulatory B cell ratio, wheezing disappearance time, shortness of breath relief time, moist rales disappearance time, and cough disappearance time were lower in the observation group(P<0.05). The maximum respiratory flow and IS maximum expiratory volume in the observation group were higher than those in the control group (P<0.05). The GH level, height, and weight obtained from two year follow up in the observation group were lower than those in the control group (P<0.05). Conclusion Budesonide suspension combined with salbutamol sulfate aerosol inhalation therapy can alleviate the inflammatory reaction, improve the lung function and immune function of children, and accelerate the disappearance of clinical symptoms, but it will affect the growth and development of children to a certain extent.

ABSTRACT

Objective@#To explore the effects of change of activity of vacuolar adenosine triphosphatase (V-ATPase) of myocardial lysosome on myocardial damage in rats after severe burn and its mechanism.@*Methods@#The myocardial lysosomes were extracted from the hearts of 12 SD rats with ultra-high speed gradient density centrifugation, then Western blotting and transmission electron microscope observation were conducted for identification. One hundred and twenty rats were divided into pure burn group, ATP group, normal control group, and bafilomycin group according to the random number table, with 30 rats in each group. Rats in pure burn group and ATP group were inflicted with 40% TBSA full-thickness scald on the back. Immediately after injury, rats in pure burn group were intraperitoneally injected with lactated Ringer′s solution in 4 mL·%TBSA-1·kg-1, and rats in ATP group were intraperitoneally injected with ATP in 0.4 mg/kg at 12 h before burn, immediately after burn, and 12 h after burn. Rats in normal control group did not receive any treatment, and rats in bafilomycin group were intraperitoneally injected with bafilomycin A1 in 0.3 mg/kg at the same time points as those of ATP group. At 24 h after burn, 30 rats from each group were collected for determining activity of V-ATPase of myocardial lysosome with coupled-enzyme assay and the expression of myocardium autophagy-related proteins microtubule-associated protein 1 light chain 3 (LC3) and P62 by Western blotting. Left ventricular arterial blood was collected to detect the content of 5 items of myocardial enzyme spectrum and cardiac troponin T (cTnT). Data were processed with one-way analysis of variance and t test.@*Results@#(1) After identification, both the expression level of lysosome-related membrane protein 1 and purity of lysosome in the sample were high, and the structure of lysosome was intact. (2) At 24 h after burn, the activity values of V-ATPase of myocardial lysosome in rats of pure burn group, ATP group, normal control group, and bafilomycin group were (2.03±0.67), (3.01±0.58), (4.29±0.26), and (1.83±0.52) μmol·mg-1·h-1, respectively. The activity value of V-ATPase of myocardial lysosome in rats of pure burn group was significantly lower than the values in ATP group and normal control group (with t values respectively 3.14 and 8.87, P values below 0.01). The activity values of V-ATPase of rats in normal control group were significantly higher than those in bafilomycin group (t=11.87, P<0.01). At 24 h after burn, the expressions of myocardial LC3 and P62 in pure burn group were significantly higher than those in ATP group and normal control group (with t values from 3.73 to 5.88, P values below 0.01). The expressions of myocardial LC3 and P62 in normal control group were significantly lower than those in bafilomycin group (with t values respectively 2.64 and 3.07, P<0.05 or P<0.01). At 24 h after burn, the content of 5 items of myocardial enzyme spectrum and cTnT in pure burn group was significantly higher than that in ATP group and normal control group (with t values from 3.24 to 16.72, P values below 0.01). The content of 5 items of myocardial enzyme spectrum and cTnT in normal control group was significantly lower than that in bafilomycin group (with t values from 2.39 to 10. 70, P values below 0.01).@*Conclusions@#The activity of V-ATPase of myocardial lysosome decreased in rats after severe burn, which can result in myocardial damage by inhibiting myocardial autophagy flux.
