Abstract
Sarcopenia is one of the common complications of cirrhosis. Studies have demonstrated that patients with cirrhosis combined with sarcopenia have a high mortality rate. The occurrence of sarcopenia may be associated with inflammatory states and metabolic abnormalities caused by changes in the gut microbiota environment, but such studies are currently relatively lacking. This article elaborates on the correlation between changes in the gut microbiota environment, as well as the diagnosis and treatment, in order to provide reference and assistance for the treatment of patients with cirrhosis and sarcopenia.

Abstract
Guiding by LC-MS/MS analysis and the GNPS Molecular Networking, five undescribed daphnane diterpenoids, tanguticanines A-E, and eleven known analogues were discovered from the whole plants of Daphne tangutica Maxim. Their structures and absolute configurations were determined via extensive NMR spectroscopic analysis, ECD calculations, and X-ray diffraction crystallography. Tanguticanine E (5) exhibited promising cytotoxicity against the HepG2 cell line with an IC50 value of 9.93 ± 0.10 μM. Further flow cytometry experiment was performed to detect cell apoptosis, and the results indicated that cytotoxic diterpenoids (tanguticanines B, D and E, altadaphnan C, gniditrin, hirsein A and simplexin) exert their effects through induction of apoptosis.

Abstract
At present, current stimulation, ultra-sound, and light therapy have become effective methods to promote wound healing. Among them, infrared light is the most widely used method and is one of the important methods to promote wound healing. The therapeutic effect of infrared light on wounds is related to the effect of photobiomodulation on cells and molecules on the skin surface, but the mechanism by which photobiomodulation of infrared light promotes wound healing has not been fully elucidated. Therefore, it is necessary to study the action characteristics and the mechanism of photo-biomodulation of infrared light in promoting wound healing. This article reviews the effect of different types of infrared light on wound healing and the mechanism of infrared light in promoting wound healing.

Abstract
Objective: To examine the effectiveness of revascularization of the deep femoral artery and its inflow vessels to treat critical limb ischemia in patients with thromboangiitis obliterans (TAO). Methods: The clinical data of 9 TAO patients with critical limb ischemia who underwent deep femoral artery and its inflow revascularization from January 2018 to October 2020 at Department of Vascular Surgery, the First Medical Center, People's Liberation Army General Hospital were retrospectively analyzed.There were all males, aged from 26 to 50 years with onset time from 1 to 7 years.All patients had severe rest pain, and 4 had ischemic ulcers or gangrene.All patients had occlusion of the deep femoral artery origins and(or) its inflow tracts, including 2 ipsilateral common iliac artery occlusion, 4 ipsilateral external iliac artery occlusion, 7 common femoral artery occlusion, and 8 deep femoral artery origins, without the involvement of the contralateral common femoral artery or its inflow tracts.Surgical procedures included femoral endarterectomy with thrombectomy, merge suture, and bypass.Technical success rate, rest pain relief, ulcer healing, patency, amputation rate, and long-term prognosis were recorded. Results: The overall technical success rate was 9/9, including 8 femoral endarterectomies with thrombectomy (with 4 patch-angioplasty with the great saphenous vein, 1 merge suture, and 3 simple sutures), 4 femoral-femoral bypasses with artificial vessels, and 1 superficial femoral artery bypass with the great saphenous vein.Rest pain disappeared after the operation immediately.The follow-up time was 10 to 44 months.All patients survived.The semi-annual patency rate was 9/9, and the one-year patency rate was 6/8.Except for one patient with significantly reduced but unhealed dorsalis ulcer up to now due to continuous heavy tobacco exposure after surgery, all others had no rest pain occurred or recurrence of foot ulcers during the follow-up.Among the 8 patients, 3 cases with recent claudication had continuous moderate tobacco exposure (10 to 20 cigarettes per day or severe passive smoking). Conclusions: For patients with thromboangiitis obliterans involved in the deep femoral artery or its inflow vessels, revascularization should be the primary choice and a good long-term prognosis is promising.Postoperative tobacco exposure (including passive smoking) is of great impact on the prognosis of TAO patients, and smoking cessation education must be reemphasized and reinforced.

Abstract
OBJECTIVE To evaluate the safety and efficacy of the drug coated balloon (DCB) with paclitaxel in patients with symptomatic peripheral artery disease (PAD). METHODS The clinical data of 18 patients, who were diagnosed as PAD and treated with DCB from October 2013 to June 2014 in Department of Vascular Surgery, People's Liberation Army General Hospital, were retrospectively analyzed.Thirteen male and 5 female patients were in the series, the mean age of the patients was (65±7) years, and the Rutherford's categories were level 3 to 5. Patients were followed up at 3- and 6-month postoperative. The main efficacy end point were late lumen loss(LLL), rate of restenosis and clinically driven target lesion revascularization (TLR). Meanwhile, the clinical events were recorded. RESULTS Mean lesion length, the percentage of total occlusions and the percentage of in-stent restenosis were (138±91) mm, 9/18 and 2/18, respectively. Rate of technical success was 18/18. At 6-month postoperative, LLL, rate of restenosis and TLR were (0.1±0.9) mm, 2/14 and 0, respectively. There was no deaths or no amputations. CONCLUSION DCB with paclitaxel is safe in patients with PAD, and associated with reductions in LLL, restenosis and clinically driven TLR 6-month postoperative.

Abstract
OBJECTIVE Elevated resting heart rate (RHR) has been shown to be a risk marker for cardiovascular disease. Results from studies on the effects of RHR in large arteries are limited to the functional changes of those arteries, while the association between RHR and aortic diameter remains largely understudied. METHODS This was a cross sectional study of hypertensive Chinese adults from rural areas. The maximum infrarenal aortic diameter (maxIAD) from renal arteries to the iliac bifurcation was obtained by ultrasound. MaxIADs in different RHR groups were compared in males and females separately because of the significant differences between sexes. Multiple regression analysis was used to determinate the correlation between RHR and maxIAD. Further interactions between three factors (BMI, smoking, and anti-hypertensive regimens) and RHR for maxIAD were examined using subgroup analysis. RESULTS 19,200 subjects were enrolled in the study, with an average age of 64.8±7.4 years and 61.6% females. Only 22 cases (0.11%) were detected with AAA, with males (n = 17) presenting a higher AAA incidence than females (n = 5). In subjects ≥65 years, there were 18 (0.19%) AAA, and 15 (83.3%) had a history of smoking. In the total subjects, the mean maxIAD ranged from 15.7±2.1 mm to 15.2±2.2 mm as RHR changed from the lowest quartile to the highest (≥84 bpm) in males, with a similar tendency observed in females. The correlation coefficient of RHR on maxIAD was -0.17 in males and -0.12 in females. Further subgroup analysis revealed that smoking exaggerated the correlation between RHR and maxIAD, but only in females. CONCLUSIONS A low AAA incidence was observed in this hypertensive Chinese population. There was a negative association between RHR and maxIAD, potentially exaggerated by smoking, especially in females.

Abstract
The class Ib molecule Qa-1(b) binds the class Ia leader peptide, Qdm, which reacts with CD94/NKG2R on NK cells. We have generated a gene that encodes the Qdm peptide covalently attached to ss(2)-microglobulin (ss(2)M) by a flexible linker (Qa-1 determinant modifier (Qdm)-ss(2)M). When this construct is expressed in TAP-2(-) or ss(2)M(-) cells, it allows for the expression of a Qdm-ss(2)M protein that associates with Qa-1(b) to generate the Qdm epitope, as detected by Qdm/Qa-1(b)-specific CTL. To test the biological significance of expression of this engineered molecule, we injected TAP-2(-) RMAS-Qdm-ss(2)M cells into C57BL/6 mice and measured their NK cell-mediated clearance from the lungs at 2 h. RMAS cells transfected with Qdm-ss(2)M were resistant to lung clearance, similar to RMA cells or RMAS cells in anti-asialo-GM(1)-treated mice, while untransfected or ss(2)M-transfected RMAS cells were rapidly cleared. Further, pulsing RMAS cells with either Qdm, a K(b)-, or D(b)-binding peptide showed equivalent protection from clearance, indicating that a single class Ia or Ib molecule can afford complete protection from NK cells in this system. In contrast, injection of RMAS cells into DBA/2 animals, which express low levels of receptors for Qdm/Qa-1(b), resulted in protection from lung clearance if pulsed with a K(b)- or D(b)-binding peptide, but not the Qa-1(b)-binding peptide, Qdm.
