ABSTRACT

Objective:To investigate the surgical techniques and advantages of Ti-Robot-assisted surgery for pelvic fragility fractures in the elderly.Methods:A retrospective review was performed on geriatric patients presenting with pelvic fractures at the Orthopedics Department of Trauma, China-Japan Union Hospital of Jilin University from September 2019 to December 2022. Minimally invasive procedures were executed with the assistance of the Ti-Robot, and the therapeutic outcomes were appraised. The cohort comprised 24 patients aged ≥60 years, consisting of 6 men and 18 women, with a mean age of 66.1±4.9 years (range, 60-77 years). Fourteen patients sustained high-energy trauma, while 10 encountered low-energy trauma. Fracture classification utilized the FFP system proposed by Rommens and Hofmann. The cohort included 20 patients with FFP II fractures (5 males, 15 females; 4 of type IIa, 12 of type IIb, and 4 of type IIc) and 4 patients with FFP III fractures (1 male, 3 females; all type IIIa). The Matta standard assessment scale gauged fracture reduction, while the Gras classification, with Ti-Robot assistance, assessed screw positioning. Postoperative functionality was holistically assessed based on the Majeed quantitative evaluation system, focusing on pain intensity, sitting, standing, walking, and daily activities. The visual analogue scale (VAS) gauged pain levels in patients with type II fractures, pre and 72 hours post-surgery.Results:According to the Matta standard assessment scale, postoperative fracture reduction quality in 24 elderly patients showed 18 as excellent, 4 as good, and 2 as fair, yielding a 92% (22/24) combined excellent and good rate. Based on the Gras classification, 52 screws were rated as excellent and 7 as good, achieving a 100% positive rate. Utilizing Majeed's modified pelvic fracture evaluation system, postoperative functional recuperation revealed 19 patients as excellent and 5 as good. There were no reports of severe internal disease exacerbations, neurological manifestations, infections, or intraoperative extensive hemorrhaging, with all patients remaining stable. Fractures exhibited robust healing during follow-ups, averaging a recovery time of 3.5±0.7 months (range, 3-5 months). The VAS for 20 patients with FFP type II fractures decreased from 6.3±2.0 pre-surgery to 4.1±1.4 post-surgery ( t=6.14, P=0.003), signifying substantial pain mitigation. Conclusion:In the elderly with pelvic fragility fractures, particularly type II, securing with channel screws is viable. The Ti-Robot-assisted minimally invasive approach is advocated due to its potential to diminish surgical risks and expedite postoperative recuperation.

ABSTRACT

Objective To analyze Mycoplasma detection and drug sensitivity test of 3 127 urogenital tract infection women ,and to provides important basis for clinical diagnosis and treatment .Methods Mycoplasma detection and drug sensitivity of 3 127 uro-genital tract infection women were detected .Results Among 3 127 cases ,1 800 patients were detected Mycoplasma ,and the posi-tivity was 57 .6% .The infection rates of Ureaplasma urealyticum(Uu) ,Mycoplasma hominis(Mh) and Uu+ Mh mixed infection were 46 .2% ,1 .2% ,10 .1% .Uu was sensitive to minocycline ,doxycycline and clarithromycin .Mh was sensitive to minocycline , doxycycline and josamycin .Uu+ Mh mixed infection was sensitive to minocycline ,doxycycline and josamycin .Conclusion Myco-p lasma infections have been the major pathogen of urogenital tract diseases ,the clinical treatment should be based on drug sensitivity test .

ABSTRACT

Through random sampling,a total of 300 residents of Beijing Changping Ming Tombs Town were selected for home-based questionnaires.The smoking rate of interviewed residents was 21.4% (53/248).The rate in men (42/125,33.6% ) was bigber than that in women ( 11/123,8.9% ).The rate in those with higher education was lower than that in those with lower educational level ( x2 =27.12,P < 0.05 ).The population awareness of tobacco hazards was 80.6% (200/248).Awareness in smokers was lower than the average awareness of ex-smokers and nonsmokers ( x2 =5.07,P < 0.05 ).The higher the education level,the higher the awareness of tobacco health hazards ( x2 ≈ 19.72,P < 0.05 ).There were differences in awareness among different age groups (x2 =13.37,P < 0.05 ).

ABSTRACT

Employing resveratrol as template molecule, acrylamide as functional monomer and ethyleneglycol dimethacrylate as cross-linkers, a core-shell resveratrol imprinted microspheres was prepared based on the surface of SiO_2 with a surface imprinting technique.The molecularly imprinted microsphere was characterized by infrared spectroscopy and scanning electron microscopy, and the results showed that the surface grafting of molecularly imprinted polymer-shell particle on SiO_2 was successful and the particles were evenly distributed.High performance liquid chromatography was also used to investigate the imprinted microsphere adsorption per formance, and the results showed that the imprinted microsphere exhibited good recognition performance.The maximum adsorption capacities were Q_(maxl)=9.087 mg/g and Q_(max2)= 13.80 mg/g by the model of Scatchard analysis.The imprinted micospheres was applied to separate resveratrol from the extraction of rhizoma polygoni cuspidate successfully.
