Atherosclerosis(AS), characterized with the accumulation of lipids on the vessel wall, is an immune-related inflammatory disease which promotes the progression of cardiovascular diseases(CVD). The imbalance of Treg/Th17 accelerates the progression of AS. Yangyin Huoxue Prescription(YHF)is an efficient traditional Chinese medicine used in the treatment of AS, but the effects of YHF on the balance of immunity have still not been clarified. This project was designed to investigate the effects of YHF on the imbalance of Treg/Th17 and AS in ApoE-/- mice induced by high-fat diet(HFD). ApoE-/- mice were given HFD to induce AS and administered low-dose YHF(18 g/kg)or high-dose YHF(36 g/kg)for 20 weeks. Atherosclerotic plaque area was analyzed by oil red O staining. Serum lipids were measured by biochemical kits. Treg or Th17 cells in peripheral blood were detected by flow cytometry. mRNA and protein expression of Foxp3 and RORγt of aortas were determined by qRT-PCR, Western blot and immunohistochemistry. Splenic CD4+T cells of mice were isolated and activated by anti-CD3/CD28, and then treated with lipopolysaccharide(LPS)and YHF. The expression of mRNA and protein of Foxp3 and RORγt were detected by qRT-PCR and immunofluorescence. It was found that YHF reduced the plaque area, decreased lipid level and increased the ratio of Treg cells in peripheral blood. Moreover, YHF increased mRNA or protein expression of Foxp3 in aortas in vivo or CD4+T cells in vitro while decreasing mRNA or protein expression of RORγt. These results suggested that YHF can regulate the imbalance of Treg/Th17 in ApoE-/- mice induced by HFD, and reduce the inflammatory stimulation of LPS on CD4+T cells, thereby improving AS.

Objective:To explore the clinical characteristics, treatment and prognosis of splenic marginal zone lymphoma.Methods:The clinical data of 51 patients with splenic marginal zone lymphoma who underwent surgical treatment at Department of Hepatobiliary in Peking University People's Hosipital from Dec 2009 to Oct 2022 were retrospectively analyzed.Results:The patients 's average age was 60.5±11.8 years old, and the ratio of male to female rate was about 1:1. As of the last follow-up date of Feb 28, 2023, 8 patients died of the primary lymphoma and 14 patients suffered from disease progression. The 5-year progression free survival rate was 68%, and the overall survival rate was 79%. Univariate analysis showed that age ≥65 years old, decreased preoperative albumin, increased bilirubin level, and increased lactate dehydrogenase bode ill for overall survival time, but none of them were independent risk factors; Age ≥65 years old and diffuse large B cell transformation were independent risk factors.Conclusions:Surgery combined with comprehensive treatment which contained rituximab is currently the main treatment method. Splenectomy remains an important treatment and diagnostic method for patients with obvious symptoms or persistent unrelieved blood count abnormalities and unexplained splenomegaly. Advanced age, elevated bilirubin and lactate dehydrogenase, decreased albumin, and diffuse large B cell transformation, it may indicate poor prognosis.

Objective :
To investigate the factors affecting concurrent sarcopenia among patients with cardiovascular diseases, so as to provide insights into early identification and prevention of cardiovascular diseases complicated with sarcopenia.
Methods:
A total of 250 inpatients with cardiovascular diseases in the Sixth Division Hospital of Xinjiang Production and Construction Corps were recruited and divided into the sarcopenia and non-sarcopenia groups according to the diagnostic criteria of sarcopenia. Subjects' basic characteristics, body mass index, blood biochemical indicators and human body composition parameters were collected using questionnaire surveys, and factors affecting concurrent sarcopenia among patients with cardiovascular diseases using a multivariable logistic regression model.
Results:
Among the 250 patients with cardiovascular diseases, there were 149 males (59.60%) and 101 females (40.40%). The overall prevalence of sarcopenia was 8.40% among the study subjects. The mean age and body mass index were (75.19±9.74) and (20.77±2.19) kg/m2 in the sarcopenia group and (65.24±11.50) years and (25.85±2.87) kg/m2 in the non-sarcopenia group. Multivariable logistic regression analysis identified age (OR=1.115, 95%CI: 1.030-1.207) and body mass index (OR=0.582, 95%CI: 0.445-0.761) were as factors affecting concurrent sarcopenia among patients with cardiovascular diseases.
Conclusion
Advanced age and low body mass index may increase the risk of concurrent sarcopenia among patients with cardiovascular diseases.

OBJECTIVETo assess the association of TLR4 gene polymorphisms with large artery atherosclerosis (LAA) stroke and liability to atherosclerosis in an ethnic Han population from northern China.
METHODSThe study has involved 286 LAA stroke patients and 300 healthy controls. The LAA group has been divided 4 subsets according to angiostenosis conditions. Polymerase chain reaction-restriction fragment length polymorphism and pyrosequencing were employed to analyze three single nucleotide polymorphism (SNPs) (rs1927914, rs1927911 and rs2149356) of the TLR4 gene. A Haploview software package was used to analyze the haplotypes.
RESULTSSNPs rs1927911 and rs2149356 were associated with LAA stroke. Genotypic and allelic frequencies of rs1927914 did not differ significantly between the two groups. Genetic variants of the three SNPs did not vary significantly between all subsets. Haplotype analysis was revealed a significant difference between the LAA group and the control group. Compared with the controls, the frequencies of haplotypes H2 and H8 were lower, and that of H3 was greater in the LAA group.
CONCLUSIONAn association between the TLR4 gene polymorphisms and LAA stroke subtype in ethnic Han population in northern China has been found. However, no association of liability to atherosclerosis in different vascular bed has been found with these polymorphisms.

Objective:
To explore the clinical effects of Nice knot combined with elastic compress and stretch in treating skin and soft tissue defect.
Methods:
From August 2017 to April 2019, a total of 23 patients, 10 males and 13 females, aged 36.5±5.3 years (range 26-76 years), were retrospectively analyzed. The defect size was 60±5.3 cm2 (28-96 cm2). Under local anesthesia, the wound was debrided thoroughly, sutured and fixed by Nice knot. The wound was fixed by elastic dressing and traction. The wound was retracted every 3 days during dressing change. The wound healing grade, healing rate, healing time, and postoperative Vancouver Scar Scale (VSS) were observed and recorded.
Results:
All operations were performed successfully in the debridement room. The operation time was 42±10.5 min (range 30-50 min), intraoperative bleeding 30±2.5 ml (range 20-60 ml), and the operation cost 180±11.5 RMB (range 160-240 RMB). Twenty patients were followed up for 4±2.5 months (range 3-6 months). The wound healing rate of 23 patients was 50%±3.5% (range 40%-56%). For the 20 patients, the wound healing rate was 65%±4.3% (range 53%-75%), 74%±4.5% (range 65%-80%), 83%±1.8% (range 76%-85%), 90%±1.6% (range 84%-95%) and 95%±3.5% (range 94%-98%) at 3, 6, 9, 12 and 15 days, respectively. The wound healing rate of 20 patients was 100% at the 42nd days of follow-up. Wound healing rate of Grade A and grade B was 95% (19/20) with scar VSS score 4(3, 6). The excellent and good rate of grade B was 80% (16/20). Two cases were sutured and fixed with Nice knot after 10 days because of the partial loss of the sutures. One case was treated with vacuum sealing drainage (VSD) on-line junction because infection was not completely controlled. Local infection was controlled and the wound was contracted by Nice junction at 1 week.
Conclusion
The treatment of skin and soft tis sue defect with Nice combination with elastic dressing and traction has the advantages of simple operation, low operation condition, short operation time, less bleeding, low cost, high wound healing grade and healing rate, suitable for basic level hospital application and promotion.

ObjectiveTo obtain the prevalence of sarcopenia in middle-aged and elderly people in Urumqi based on the 2020 updated based on the 2020 updated Consensus Report 2019 of Asian Working Group for Sarcopenia (AWGS2019), and to further explore the association between sarcopenia and metabolic syndrome (MS). MethodsA total of 1 438 middle-aged and elderly people (aged≥50 years) in Urumqi from July 2018 to January 2019 were selected as the research subjects. Data were collected by questionnaire survey, physical examination and laboratory test. Skeletal muscle mass,grip strength and 4 m walking speed were used to represent muscle mass, muscle strength and body function, respectively. Bioelectrical impedance analysis (BIA) was used to measure human body components. Based on the diagnostic criteria of sarcopenia recommended by AWGS2019, the prevalence of sarcopenia in people over 50 years old was obtained. Multivariate logistic regression model was used to explore the correlation between sarcopenia and MS in middle-aged and elderly people of different genders. ResultsThere were 194 patients with sarcopenia, with a prevalence of 13.49%. The prevalence was 15.56% in males and 12.12% in females. There was no significant difference in the prevalence of MS between male sarcopenia group (40.45%) and non-sarcopenia group (38.92%), while the prevalence of MS in female sarcopenia group (39.04%) was higher than that in non-sarcopenia group (27.56%). Multivariate logistic regression analysis showed that sarcopenia was a related factor of MS. Compared with non-sarcopenia, the risk of MS in male sarcopenia group was higher (OR=2.11,95%CI: 1.15‒3.88 ). ConclusionSarcopenia increases the risk of MS in middle-aged and elderly people, with a greater risk in men. Fully understanding of sarcopenia is helpful to early identify high-risk groups of MS and prevent the occurrence of MS.
