ABSTRACT

OBJECTIVE@#To investigate the surgical skills and clinical curative results of arthroscopic treatment of ankle instability combined with anteromedial impingement syndrome.@*METHODS@#From February 2019 to August 2020, 13 patients with ankle instability combined with anteromedial impingement were retrospectively analyzed. There were 10 males and 3 females with age of (40.0±15.1) years old. The course of disease was(44.1±33.2) months. All patients had history of ankle sprain. MRI showed the injury of anterior talofibular ligament. All patients had anteromedial pain and pressing pain when ankle dorsiflexion. All patients were treated with ankle debridement and Brostr?m-Gould surgery under ankle arthroscopic. Postoperative results were evaluated by VAS(visual analogue scale) and AOFAS-AH(American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale, AOFAS-AH).@*RESULTS@#All 13 patients completed the surgery successfully with an operative time of 60 to 90 minutes. All the surgical incisions healed by first intention, and no complications such as incision infection, skin necrosis and neurovascular injury. Follow-up time was (18.1±4.7) months. At the latest follow-up, the VAS score was 1.2±1.1, which was significantly lower than the preoperative score 4.8±1.5 (P<0.05);the AOFAS-AH score 94.2±5.1 was significantly higher than the preoperative score 65.5±11.5 (P<0.05). The AOFAS-AH score at the final follow-up ranged from 84 to 100. All patients walked with normal gait without ankle instability or impingement recurrence.@*CONCLUSION@#Ankle anteromedial impingement syndrome combined with ankle instability is easy to be ignored clinically. Such kind of anteromedial impingement syndrome is mostly related to osteophyte at dorsal medial talar neck. Arthroscopic treatment of ankle instability combined with anteromedial impingement syndrome has satisfactory curative effect with safety and minimal injury.

ABSTRACT

OBJECTIVE: To establish an indicator system for risk assessment on occupational dust hazards and verify its application. METHODS: Using Delphi method,two rounds of investigation were made from 30 experts who work on frontline occupational health. The indicator system for risk assessment was established based on the investigation,statistics and boundary value,in fully consideration with the interaction of three basic elements of“dust inherent characteristics-laborers factors-influencing factors”. The indicator system was applied to evaluate the risk of 90 workplaces in the presence of dust occupational risk factors. RESULTS: The positive coefficient of experts' opinion was 90%,and the coefficient of experts' authority was 0. 808. The coefficient of experts' consensus was 0. 50( χ~2= 120. 56,P < 0. 01). The indicator system for risk assessment on occupational hazards of dust factors has been successfully established. This system included three class A indicators,nine class B indicators and twenty-eight class C indicators. The total coincidence rate of assessments on the risk level of occupational dust hazards of workplaces was 60%( Kappa = 0. 452,P < 0. 01). CONCLUSION: This indicator system was objective,scientific and feasible,and could reflect the actual levels of occupational dust hazards.

ABSTRACT

<p><b>OBJECTIVE</b>To detect the effect of Nocardia rubra cell wall skeleton (Nr-CWS) on tumorigenicity induced by TC-1 cells and to clinically study anti-human papillomavirus effect of Nr-CWS in lower genital tract of women.</p><p><b>METHODS</b>Tumor model was established by injecting TC-1 cells subcutaneously in SCID mice, then divided them into 3 groups randomly and injected with isovolumetric physiological saline, 60 micrograms/ml Nr-CWS and 120 micrograms/ml Nr-CWS respectively, the growth of tumors was measured one week later. Nr-CWS was applied on 45 HPV positive women whose TCT test was normal and without cervical erosion 2-3 days after menstruation. HPV was detected again 3 months later to explore the effect of Nr-CWS on HPV infection in female lower genital tract.</p><p><b>RESULTS</b>The animal experiment showed the weight of transplanted tumors in treated group was less than that of control group (chi2=12.5, P= 0.002). The tumor inhibition rate was 59.1 percent and 84.2 percent in the groups treated with Nr-CWS 60 and 120 micrograms/ml Nr-CWS; the results of HPV detection in 23 out of the 45 cases (51.1 percent) became negative after the 3-month treatment; the viral load was reduced in 9, and there was no change in viral load in 13 cases. Significant difference was found between the rates of undetectable viral load and the natural viral disappearance rate (P less than 0.05).</p><p><b>CONCLUSION</b>Nr-CWS has an inhibitory effect to TC-1 cell tumorigenesis and clinical application of Nr-CWS may eliminate the HPV infection in lower genital tract of a considerable proportion of women with HPV infection.</p>
