Objective To observe the relationship of right internal jugular vein (RIJV)and common carotid artery (CAA)by scanning strictly from the anterior to posterior using ultrasound at different head rotation.Methods Using ultrasonic scanning,the anatomic features of RIJV and CAA both at thyroid cartilage level (prominentia laryngea level)and at the apex of the angle formed by the division of the sternocleidomastoid muscle (triangle level)with 0°,1 5°,30° and 45° right rotation were observed in 131 patients with ASA physical status Ⅰ or Ⅱ (male 55 cases,female 76 cases, aged 18~74 years).Based on the ultrasound images,the safe puncture range,the overlapping ratio, the angle between the horizontal axis and the line from the midpoint of RIJV to that of CAA (αangle) were measured.In addition,the relationship between the RIJV and CAA was defined as anterior-lat-eral, lateral, posterior-lateral or extremely-posterior-lateral position according to α angle. Results The safe puncture range of RIJV augmented as head rotated from 0° to 30° position(P <0.05);The safe puncture range of RIJV at triangle level was significantly higher than at prominentia laryngea level at all the four head positions(P <0.05).The overlapping degree decreased as head rota-ted from 0°to 30°head position at prominentia laryngea level(P <0.05).No siginificant differences of the overlapping degree were found between head positons at triangle level;The overlapping degree at triangle level was less than at prominentia laryngea level when at 0°and 1 5°head positon(P <0.05). At both prominentia laryngea and triangle levels,RIJV located mainly at lateral and posterior-lateral positions.In addition,the part of lateral position increased while the part of posterior-lateral position decreased as the head rotated from 0°to 45°position(P <0.05).Conclusion The puncture conditions for RIJV catheterization were more optimal at 30°to 45°head rotation for a safer puncture range and less overlapping between RIJV and CAA.RIJV located mainly at lateral and posterior-lateral positions at different rotations and RIJV gradually shifted to lateral position while head rotation increasing.It would be much better to select triangle level for central venous catheterization than prominentia laryn-gea level.

OBJECTIVETo evaluate the prognosis of cervical intraepithelial neoplasia grade 1 (CIN1) at different follow-up time points in Chinese women and the relationship with high-risk human papillomavirus (HR-HPV) infection.

METHODSBiopsy-confirmed CIN1 women were followed up from cervical cancer screening cohorts established during 1999 to 2008 in Xiangyuan county, Yangcheng county, Qinxian county and Wuxiang county, Shanxi Province.In each follow-up visit, participants were examined by visual inspection with acetic acid, liquid-based cytology and HR-HPV DNA testing. Those with any positive results received colposcope and biopsies. The cumulative incidence rates of CIN grade 2 or worse (CIN2+) and CIN grade 3 or worse (CIN3+), regression rates and persistent rates were calculated using pathological findings as a gold standard. The risks of progression related with HR-HPV were evaluated stratified by baseline and follow-up HR-HPV status.

RESULTSA total of 228, 224, 261 and 105 CIN1 women received the 1-year, 2-year, 6-year and 11-year follow-up exams, respectively. The cumulative incidence rate of CIN2+ among baseline HR-HPV positive women was 4.8% (6/126), 10.7% (16/150), 16.9% (29/172) and 35% (19/55) in the above follow-up visits, respectively, and their risk of progression was 2.7(95%CI:0.3-22.0), 2.9 (95%CI:0.7-12.1), 12.0 (95%CI:1.7-86.2) and 30.6 (95%CI:1.9-493.5) times higher than baseline HR-HPV negative women. Moreover, the cumulative incidence of CIN2+ among women with positive HR-HPV both at baseline and follow-up visit was 11% (6/55), 14% (6/42), 17% (10/60) and 50% (13/26) in the above follow-up visits, respectively.No new CIN2+ cases were found among those with negative HR-HPV both at baseline and follow-up visits.

CONCLUSIONGiven that CIN1 progression is related to HR-HPV infection, different follow-up intervals and strategies for CIN1 should be taken according to HR-HPV infection status.

Objective:To investigate the clinical effects of perforator flaps in the repair of limb defects.Methods:Anterolateral thigh perforator flap (ALTP), deep inferior epigastric perforator flap (DIEP), posterior in- terosseous artery perforator flap (PIAP), thoracodorsal artery perforator flap (TDAP), medial sural artery perforator flap (MSAP) and radial collateral artery perforator flap (RCAP) were used to repair 56 cases of limb wounds from Novem- ber, 2016 to October, 2018. The sizes of soft tissue defect were ranged from 1.5 cm×1.5 cm to 10.0 cm×24.0 cm, while the sizes of flap were ranged from 2.0 cm×2.0 cm to 11.0 cm×25.0 cm. The recipient sites were all sutured di- rectly. The flaps survived and wound healing were observed postoperatively. Appearance, texture, recovery of the limb function, shape and function of donor site were followed-up regularly.Results:One case of venous crisis occurred on the 3rd day after inferior epigastric artery perforator flap surgery, and survived after exploratory surgery with the necrosis in the distal part of the flap, which healed after dressing. Other 55 flaps all survived. Both recipient site and donor site healed in primary union. The color of the flaps was normal. The skins were soft, and the functions of the limbs recovered well. Only a linear scar remained in the donor area without dysfunction.Conclusion:The perforator flap surgery is reliable for limbs repair and can be promoted and applied.

Objective:To preliminarily investigate the effect of blue light on the biological activity of human skin keratinocytes, fibroblasts and melanocytes.Methods:Discarded foreskin tissues were collected from 10 healthy children aged from 3 to 12 years after circumcision surgery in the First Affiliated Hospital of Kunming Medical University from June 2021 to December 2021. After epidermis-dermis separation, selective culture was performed to isolate keratinocytes, fibroblasts, and melanocytes. According to the pre-experiment results, the above three types of cells were irradiated with 440 - 450 nm blue light at doses of 0, 5, 10, 20, 30, and 40 J/cm 2, and then continued to be cultured for 0, 6, 24, and 48 hours. Cell counting kit 8 (CCK8) assay was performed to evaluate cellular proliferative activity at each time point, enzyme-linked immunosorbent assay (ELISA) to detect levels of interleukin (IL) -18, IL-33, nerve growth factor (NGF), and granulocyte-macrophage colony-stimulating factor (GM-CSF) secreted by keratinocytes, as well as levels of IL-33 and keratinocyte growth factor (KGF) secreted by fibroblasts, NaOH lysis method to determine melanin synthesis rates in melanocytes, and Western blot analysis to determine the relative expression of tyrosinase (TYR), tyrosine-related protease 1 (TRP-1) and dopachrome isomerase (DCT) in melanocytes. Two-way analysis of variance was used to analyze group effects, time effects and interaction effects. Results:After irradiation with blue light, the cellular proliferative activity significantly differed among different doses of blue light irradiation groups and different time points in keratinocytes ( Ftime = 516.20, Fdose = 421.20, Finteraction = 25.05, all P < 0.003), fibroblasts ( Ftime = 129.30, Fdose = 477.80, Finteraction = 10.91, all P < 0.003), and melanocytes ( Ftime = 77.61, Fdose = 138.70, Finteraction = 3.50, all P < 0.003) ; immediately after irradiation, the proliferative activity of keratinocytes and fibroblasts was significantly lower in the 20 - 40 J/cm 2 blue light group than in the 0 J/cm 2 blue light group (all P < 0.003), and the proliferative activity of melanocytes was significantly higher in the 5 J/cm 2 blue light group than in the 0 J/cm 2 blue light group ( P < 0.003) ; the proliferative activity of the 3 types of cells showed decreasing trends with the increase of blue light irradiation doses and culture time. ELISA showed that the concentrations of IL-18, IL-33, NGF, and GM-CSF secreted by keratinocytes, as well as the concentrations of IL-33 and KGF secreted by fibroblasts, tended to increase with the increase of blue light irradiation doses and culture time. The melanin synthesis rates in melanocytes significantly differed among different doses of blue light irradiation groups and different time points ( Ftime = 833.50, Fdose = 249.40, Finteraction = 81.38, all P < 0.003) ; during 0 - 24 hours after blue light irradiation, the melanin synthesis rates tended to increase with the increase of blue light irradiation doses and time; during 24 - 48 hours, the melanin synthesis rates showed decreasing trends with the increase of blue light irradiation doses and culture time compared with that at 24 hours after irradiation; 24 hours after irradiation, the melanin synthesis rates were significantly higher in the 5, 10, 20, 30 and 40 J/cm 2 blue light groups (159.50% ± 10.88%, 218.76% ± 8.49%, 333.72% ± 7.72%, 393.29% ± 6.00%, 427.21% ± 8.39%, respectively) than in the 0 J/cm 2 blue light group (102.29% ± 6.57%, all P < 0.003). The relative expression of TYR ( Ftime = 67.94, Fdose = 28.99, Finteraction = 3.71, all P < 0.003), TRP-1 ( Ftime = 21.73, Fdose = 8.38, both P < 0.003) and DCT ( Ftime = 34.51, Fdose = 11.79, both P < 0.003) in melanocytes significantly differed among different doses of blue light irradiation groups and different time points, and tended to increase with the increase of blue light irradiation doses and culture time. Conclusion:Blue light irradiation at doses of 5 - 40 J/cm 2 could inhibit the proliferative activity of human skin keratinocytes, fibroblasts, and melanocytes, and the inhibitory effect tended to increase with the increase of blue light irradiation doses, except an enhancing effect on the proliferative activity of melanocytes observed immediately after irradiation with blue light at 5 J/cm 2; additionally, blue light irradiation at 5 - 40 J/cm 2 could enhance the expression of melanin synthesis-related enzymes in melanocytes, and increase the melanin synthesis rate in melanocytes over a short period of time.
