Objective : To survey the current situation and analyze the relevant influencing factors of sleep quality in adolescent patients with temporomandibular joint anterior disc displacement. Methods: This study has been reviewed and approved by the Ethics Committee, and informed consent has been obtained from patients. A convenience sampling method was used to investigate 120 adolescent patients with temporomandibular joint anterior disc displacement in the outpatient department of stomatology in a grade A tertiary hospital in Shanghai using the general data questionnaire, the Pittsburgh sleep quality index scale (PSQI), the Chinese middle school student mental health scale (MMHI-60) and the pain visual analog scale (VAS). Descriptive analysis, single factor analysis, correlation analysis and multiple regression analysis were used to explore the relevant influencing factors. Results: The PSQI score of adolescent patients with temporomandibular joint anterior disc displacement in this study was 7.77 ± 4.63. There was a statistically significant difference in sleep quality among patients with different academic pressures and levels of sleep bruxism (P<0.05). The sleep quality score was positively correlated with the pain score (r = 0.45, P<0.001) and positively correlated with the psychological score (r = 0.74, P<0.001). The degree of pain can affect the patient's sleep quality, and those with good mental health have better sleep quality. The results of regression analysis showed that academic stress (OR = 2.511, 95% CI =1.307 ~ 4.828), bruxism (OR = 3.694, 95% CI = 1.394 ~ 9.791), pain score (OR = 2.104, 95% CI =1.095 ~ 4.041) and psychological score (OR = 1.039, 95% CI = 1.021 ~ 1.058) were statistically significant. Conclusion The sleep quality of adolescent patients with temporomandibular joint anterior disc displacement is generally poor. Academic pressure, sleep bruxism, pain and mental health are the influencing factors of sleep quality.

Objective To understand the epidemiology of clinically isolated Acinetobacter baumannii(A.bauma-nnii)in Hunan Province.Methods Bacterial antimicrobial resistance surveillance was carried out according to the requirements of the technical program of National Antimicrobial Resistance Surveillance System.Clinical data of Acinetobacter spp.reported to Hunan Provincial Antimicrobial Resistance Surveillance System by multiple centers in Hunan Province from 2012 to 2021 were summarized and analyzed with reference to the standards of the American Clinical and Laboratory Standards Institute.Results A total of 169 438 strains of Acinetobacter spp.were detected during the 10-year period,with the detection rate of A.baumannii being the highest(82.74％).70 923 strains(53.63％)of carbapenem-resistant A.baumannii(CRAB)and 58 149 strains(43.97％)of carbapenem-sensitive A.baumannii(CSAB)were detected respectively.Both CRAB and CSAB were detected most frequently in the age group＞70 years,which were 34.44％and 32.02％,respectively.The percentage of CRAB and CSAB detected in the intensive care unit were 34.80％and 11.31％,respectively.CRAB and CSAB were mainly isolated from spu-tum/bronchoalveolar lavage fluid,followed by pus/secretion,urine,and blood.The resistance rates of CRAB to commonly used antimicrobial agents didn't change much during the 10-year period.Resistance rates of CRAB to ceftazidime and cefepime were both＞84％,to ampicillin/sulbactam and piperacillin/tazobactam were both＞82％,to aminoglycosides and quinolones were both＞59％,to minocycline and polymyxin B were 15.9％-25.0％and 1.3％-6.9％,respectively.CSAB were sensitive to commonly used antimicrobial agents.Conclusion The isolation rate of CRAB is high and there is no significant change in resistance to commonly used antimicrobial agents.

Objective:To explore the curative effects of ultrathin anterolateral femoral flap in one-stage split-finger repair of palmar combined with multiple finger wounds.Methods:A retrospective observational study was conducted. From October 2016 to June 2018, 20 patients with wounds on palms and multiple fingers who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 15 males and 5 females, aged 18 to 77 years. After debridement, the wound area was 8 cm×4 cm-17 cm×12 cm. The wound was repaired by ultrathin anterolateral femoral flap with area of 9 cm×5 cm to 19 cm×13 cm. According to the wound condition of finger, the finger division was performed in one stage, and the length-to-width ratio of the split-finger flap was 2.0:1.0-2.5:1.0. During the surgery, the descending branches of lateral circumflex femoral artery and accompanying vein of flap were anastomosed end-to-end to the radial artery and vein in the recipient area, respectively, and the anterolateral femoral cutaneous nerve of flap was bridged with the superficial branch of radial nerve in the recipient area. The wounds in the donor area of flap in 14 patients were sutured directly, the wounds in the donor area of flap in 3 patients were repaired by relay superficial iliac circumflex artery perforator flap, and the wounds in the donor area of flap in 3 patients were covered by free trunk medium-thick skin graft. The survival of flap, occurrence of vascular crisis and other complications, and healing of wounds in the donor area of flap were recorded. The appearance of flap, scar hyperplasia in the donor and recipient areas and the patients' satisfaction with the shape and function of the donor and recipient areas were followed up. In 1 year after surgery, the two-point discrimination distance of the flap was measured, and the recovery of hand function was evaluated by the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association.Results:The flaps of 17 patients survived without vascular crisis or other complications after surgery. The flap of 1 patient had poor blood circulation and partial necrosis, and the wound was healed 14 days after dressing change and grafting of split-thickness skin graft from head. Two patients had mild cyanosis at the margin of flap after surgery, which disappeared spontaneously 5 days later. Incisions at donor site, relay flaps, and skin grafts of all patients survived well. After surgery, the color and texture of flap were basically the same as that of the normal skin of hand, and linear scars were observed in the donor and recipient areas. The patients were satisfied with the recovery of appearance and function of donor and recipient areas. After 1 year of follow-up, the patients' hand sensory function recovered well, the two-point discrimination distance of flap was 4-6 mm, and the recovery of hand function was evaluated as excellent in 18 cases and good in 2 cases.Conclusions:The ultrathin anterolateral femoral flap in repairing the palmar combined with multiple finger wounds in one-stage split-finger can significantly reduce the number of surgeries and improve the function and beauty of the hand, so it is worthy of clinical promotion.

Actin-binding proteins (ABPs) are important components of the F-actin cytoskeleton and affect the dynamics of F-actin by promoting the polymerization and depolymerization of actin. Numerous studies have shown that F-actin and actin-binding proteins are involved in all stages of carcinogenesis. Our analysis of esophageal carcinoma proteomic data showed that the actin-binding protein EHD2 (E p s l 5 homology domain-containing protein 2) is expressed at low levels in esophageal squamous cell carcinoma tissues and patients with lower EHD2 expression had poorer prognosis. Previous studies have revealed that EHD2 is involved in the regulation of glucose metabolism, autophagy and tumor cell migration. However, the role and mechanism of EHD2 in esophageal squamous cell carcinoma progression remain unclear. This study aimed to explore the effect of EHD2 on the proliferation of esophageal squamous cell carcinoma. Immunofluorescence and cell fractionation analysis showed that EHD2 was not only localized in the cell membrane and cytoplasm, but also in the nucleus. Colony formation, EdU labeling and flow cytometry were used to determine the effect of EHD2 on the proliferation of esophageal squamous cell carcinoma. The results showed that overexpression of EHD2 and EHD2-3×NLS (nuclear localization signal) inhibited proliferation, cell cycle G

OBJECTIVE: To observe the effect of moxibustion on skin lesions and immune inflammatory response in psoriasis mice, and to explore the possible mechanism of moxibustion for psoriasis. METHODS: A total of 32 male BALB/c mice were randomly divided into a normal group, a model group, a moxibustion group and a medication group, 8 mice in each group. Psoriasis model was induced by applying 5% imiquimod cream on the back for 7 days in the model group, the moxibustion group and the medication group. At the same time of model establishment, the moxibustion group was treated with suspension moxibustion on skin lesions on the back, 20 min each time, once a day; the medication group was treated with 1 mg/kg methotrexate tablet solution by gavage, once a day. Both groups were intervened for 7 days. The daily changes of skin lesions were observed, and the psoriasis area and severity index (PASI) score was evaluated; the histopathological changes of skin lesions were observed by HE staining; the positive expression of proliferating cell nuclear antigen (PCNA) and T lymphocyte surface marker CD₃ were detected by immunohistochemistry; the expression level of serum interleukin (IL) -17A was detected by ELISA, and the relative expressions of tumor necrosis factor-α (TNF-α), IL-1β and IL-6 mRNA in skin lesions were detected by real-time PCR. RESULTS: The increased and hypertrophy scale, dry skin, red and swollen epidermis and obvious infiltration were observed in the model group, and each score and total score of PASI were higher than those in the normal group (P<0.01). The scale score, infiltration score, and total score of PASI in the moxibustion group were lower than those in the model group (P<0.01); the infiltration score and total score of PASI in the medication group were lower than those in the model group (P<0.01, P<0.05). The inflammatory cell infiltration in the model group was obvious, and the thickness of epidermal layer was increased compared with that in the normal group (P<0.01); the inflammatory cell infiltration and Munro micro abscess were decreased in the moxibustion group and the medication group, and the thickness of epidermal layer was decreased compared with that in the model group (P<0.01). Compared with the normal group, the positive cell number of PCNA and T was increased (P<0.01), and the body mass was decreased, and the spleen index was increased (P<0.01), and the expression of serum IL-17A and the relative expression of TNF-α, IL-1β and IL-6 mRNA in the skin lesions was increased in the model group (P<0.01). Compared with the model group, the positive cell number of PCNA and T was reduced (P<0.01), and the spleen index and the relative expression of TNF-α, IL-1β and IL-6 mRNA were reduced (P<0.01) in the moxibustion group and the medication group; the body mass of mice in the moxibustion group was higher than that in the model group (P<0.01); the content of serum IL-17A in the medication group was lower than that in the model group (P<0.01); the relative expression of TNF-α, IL-1β mRNA in the moxibustion group was higher than that in the medication group (P<0.01). CONCLUSION Moxibustion could effectively improve the scale and infiltration of skin lesions in psoriasis mice. Its mechanism may be related to inhibiting inflammatory response and regulating immunity.
