Résumé
Background@#Cigarette smoking and physical inactivity are critical risk factors for the prevalence of metabolic syndrome (MetS). This study aimed to investigate the prevalence of MetS and its related factors in adult men based on their physical activity (PA) levels and smoking status. @*Methods@#In this cross-sectional analysis, 5,984 adult men aged 19-64 years were included based on the 7th Korean national health and nutrition examination survey (2016-2018). MetS was diagnosed based on the National Cholesterol Education Program Adult Treatment Panel III criteria, and PA was categorized as light PA (LPA), moderate, and vigorous PA (VPA). We used linear and logistic regression models to analyze the association between PA, MetS, and smoking status. @*Results@#The prevalence of MetS in adult men was 27.8%, with the risk of MetS increasing with smoking and LPA. The risk of MetS significantly reduced by 64.7% in the VPA and quitter groups compared to that in the LPA and smoking groups (odds ratio, 0.353; 95% confidence interval, 0.232-0.539; P=0.001). @*Conclusions@#Our study findings suggest that VPA may be an effective means of reducing the risk of MetS in adult men, while smoking and LPA may increase the risk of MetS.

Objective:To investigate the clinical effect of perforator flap of distal cutaneous perforator of medial plantar artery in recon struction of destructive defect in the base plane of proximal phalange of great toe.Methods:Twenty-six patients were treated in the Department of Foot and Ankle Surgery of Xuzhou Renci Hospital from September 2017 to December 2021. The patients were 24 males and 2 females, aged 26 to 60 years old. There were 12 defects in left foot and 14 in right foot. All the defects were the residual wounds at the first metatarsophalangeal joint with the defect at 2.0 cm × 3.0 cm - 4.0 cm × 5.0 cm in size. The flaps pedicled with distal cutaneous perforator of the medial plantar artery were used to repair the defects, with a size at 3.2 cm× 4.2 cm in average. Skin grafts were employed to repair the donor sites. Postoperative patient management including lifting the affected limbs and keeping warm, anti-infection, detumescence, anti-coagulation and pain relief.Results:All patients were entered in postoperative follow-up at outpatient clinic for 1-3 years. Twenty-two flaps survived after surgery, except 4 that had dark purple edge indicating venous congestion. Blood supply of the flap was regained after the tension of the flap was relieved by interval suture removal. Appearance of flaps was good, without obvious swelling nor pigmentation, good in elasticity, in hard texture and with good wear resistance. Patients showed no limp of the affected limbs, and without restriction in wearing shoes or walking. The function of feet was evaluated according to the American Orthopedic Foot and Ankle Societ (AOFAS) I50, with 24 patients in excellent and 2 in good.Conclusion:The anatomy of the flap pedicled with distal cutaneous perforator of the medial plantar artery is relatively constant. It provides a blood supply and does not affect the trunk of major artery. The flap has a thick skin cuticle hence it is wear-resistant. This flap provides a choice to the repair of a defect at proximal segment of great toe.

@#AIM: To investigate interocular differences in macular ganglion cell complex(mGCC)thickness in normal healthy subjects, and to determine cutoffs for interocular differences in mGCC thickness in normal healthy subjects.<p>METHODS: This was a cross-sectional study. mGCC thickness were measured in 236 healthy volunteers(472 eyes)using optical coherence tomography(OCT). The differences and the relationships of mGCC thickness between right and left eyes were analyzed. <p>RESULTS: For the right eyes, the mean average mGCC thickness was 91.99±6.61μm, and for the left, 91.75±9.93μm, with no significant difference. The mean mGCC thickness among superior and inferior in the right eye were 92.32±6.66μm and 91.27±8.87μm, respectively. The mean mGCC thickness among superior and inferior in the left eye were 92.05±6.55 and 91.51±6.76μm, respectively. It is comparable between the two eyes at different area. The P2.5 and P97.5 percentiles of interocular difference for mean average mGCC thickness were -4.82μm and 4.36μm, for superior mGCC thickness, -5.79μm and 6.42μm, and for inferior mGCC thickness, -7.21μm and 6.28μm. There was a strong correlation in the corresponding area between the right and left eyes for the mGCC thickness.<p>CONCLUSION: mGCC thickness shows significant interocular symmetry in normal subjects. Interocular difference exceeding the normal limits should be considered significantly asymmetrical, and may be indicative of glaucoma.

BACKGROUND:Osteoarthritis, a degenerative joint disease, is not only a result from the breakdown of joint cartilage and underlying bone, but also an imbalance of bone remodeling and crosstalk among tissues in the joints. OBJECTIVE: To review the effect of bone-cartilage crosstalk in the progression of osteoarthritis and its new treatment strategy. METHODS: A computer-based search of PubMed and CNKI databases was performed for relevant literatures about the relationship between the progress of osteoarthritis and the bone-cartilage crosstalk published from 2007 to 2017. The keywords were cartilage, interaction, osteoarthritis, pathogenesis, cytokines, signaling pathway in English and Chinese, respectively. The relationship between the progress of osteoarthritis and the bone-cartilage crosstalk was summarized in views of cytokines, signaling pathway, and new treatment strategy. RESULTS AND CONCLUSION: Totally 169 articles were retrieved, and finally 54 eligible papers were enrolled based on the inclusion and exclusion criteria. There is a close physical association between subchondral bone and cartilage, and the bone-cartilage interface is a functioning synergistic unit. Increased vascularization, micro-crack formation and abnormal bone remodeling may accelerate the molecules transporting from cartilage to bone in osteoarthritis. Therefore, the bone-cartilage crosstalk plays a pivotal role in the occurrence and development of osteoarthritis.

This study was conducted to reveal genetic diversity among 100 Osmanthus fragrans cultivars using amplified fragment length polymorphism (AFLP) markers. Eight AFLP primer combinations produced a total of 443 polymorphic fragments with an average of 64 per primer combination. The percentage of polymorphic bands (86.81 percent), the resolving power (Rp) (32.71) and the PIC values (0.331) showed the efficiency of used primer combinations. The revealed AFLP makers were effective in distinguishing all the cultivars considered. Cluster analysis were performed to assess patterns of diversity among cultivars and showed the abundant genetic diversity. The overall distribution pattern of molecular variation suggested that 93.33 percent of the total genetic variance was within the identified groups and 6.67 percent of the genetic variation was among the identified groups. Our results showed that AFLP markers are useful for Osmanthus fragrans germplasm discrimination as well as for investigation of genetic diversity and variation. The information will facilitate germplasm identification, conservation and new cultivar development.
