Value of negative pressure sealing drainage on wound healing of Gustilo IIIB and IIIC open fractures

BACKGROUND Gustilo III fractures have a high incidence and are difficult to treat.Patients often experience difficulty in wound healing.Negative pressure drainage technology can help shorten wound healing time and has positive value in improving patient prognosis.AIM To explore the clinical value of the negative pressure sealing drainage technique in wound healing of Gustilo IIIB and IIIC open fractures.METHODS Eighty patients with Gustilo IIIB and IIIC open fractures with skin and soft tissue injuries who were treated in the Second People’s Hospital of Dalian from March 2019 to December 2021 were selected as the research subjects.They were divided into a study group(n=40,healed with negative pressure closed drainage)and a control group(n=40,healed with conventional dressing changes)according to the variation in the healing they received.The efficacy of the clinical interventions,the variations in the regression indicators(time to wound healing,time to fracture healing,time to hospitalization),and the conversion and healing of bacterial wounds were compared 1-3 mo after the intervention.RESULTS The total effective rate of patients among the study group was 95.00%(38/40),which was notably higher than 75.00%(30/40)among the control group(P<0.05).The wound healing time,fracture healing time,and hospital stay of the patients in the study group was shorter than the control group(P<0.05).After the intervention,the negative bacterial culture at the wound site rate and wound healing rate of the patients among the study group increased compared to the control group(P<0.05).CONCLUSION Negative pressure sealing and drainage technology has a good therapeutic effect on patients with Gustilo IIIB and IIIC open fracture wounds with skin and soft tissue injury.It can notably enhance the wound healing rate and the negative rate of bacteria on the wound surface and help to speed up the recovery process of patients.

Values Research and Education by Yi-ological-Systemic-Typological Method in Integration Context

The study of values in the world at present almost follows Western theories and techniques. This is a matter of course in the field of science--technology, but it turns to be much more complicated in the field of social sciences and humanities, because this area is heavily dependent on particular nationalities. Furthermore, the most commonly used in the value research methodology is questionnaire, and using a questionnaire to study values is still restrictive. To overcome this disadvantage, we have developed a Yi-ologieal-Systemic-Typological method to use mostly in studying values. According to Yi-ological method, value education helps learners to recognize values among non-values, non-values among values. According to Systemic method, it helps learners see the changing of values over the time, the close relationship and interaction between values with non-values. Value education according to Typological method helps learners recognize the similarities and differences between cultures, both apart and close ones.

Research Progress of Akebia trifoliata (Thunb.) Koidz.

This article mainly intro- duced the research advance in the botanical characteristics, nutrition and medicinal value, further development and utilization of A. trifoliata, and the developing orientation of A. trifoliata in the future.

Studies on the Evolution and Value of the Item Setting of the Summer Olympic Games

The Olympic Games, as the global sports event, attract many countries in the world to participate in and they always take obtaining the right of holding it as the pride of the country. With the constant development of the Olympic Games, people have proposed higher requirements for it and the reformation is eagerly needed and the reformation is mainly concentrated on the item setting. According to a large amount of theoretical research to the item setting of Olympic Games in academia, there is big issue about the item setting for the current Summer Olympic Games which has sustained for a long time. Its practical representations are the contradiction between narrowing the scope of the Olympic Games and borrowing in the new items and the contradiction of gender equality in item setting and also the contradiction of balancing the business value and social value. Therefore, this thesis will mainly study on the evolution and value of the item setting of the Summer Olympic Games and propose reasonable improvement measures for the issue of the item setting, combining with the practical conditions, and thus to better promote the sustain development of the Summer Olympic Games.

Application of TCT to Research on Value in Screening for Cervical Cancer in Postmenopausal Women

Objective:To study the screening for cervical cancer in postmenopausal women in liquid-based cell test(TCT)application value.Methods:From January 2023 to March 2024 hospital check-ups and outpatient reached 400 cases of postmenopausal women,and they were TCT and HPV detection,during the study period to pathological diagnosis of numerical results as the standard,analysis of TCT detection application of screening for cervical cancer in postmenopausal women and the effect.Results:After the TCT detection,the inflammation group and normal group by use of HPV testing positive rate higher than other groups(P<0.05).Hospital after pathological diagnosis and research,after the screening system found CINⅠlevel and above cases about 39 cases,the TCT and HPV detection rate of positive difference is not obvious,and there is no statistical significance(P>0.05).Joint test analysis,the sensitivity and specificity were higher than that of TCT and HPV testing positive(P<0.05).Conclusion:TCT detection screening for cervical cancer in postmenopausal women is of great importance to the application,if you can join HPV testing,help to improve the detection sensitivity,avoid missed diagnosis of problems,and then for treatment and later restore to lay a solid foundation.

Valuing Potential Benefits of Research into the Biological Control of Californian Thistle （Cirsium arvense）： A Bioeconomic Model

The present research developed a bioeconomic model for control of Californian thistle （Cirsium arvense L. Scop.） in intensive, lowland sheep pastures in New Zealand. Production costs included two control methods： herbicides and defoliation, with defoliation encompassing both physical means and biocontrol measures. The model was used to examine the economic value of a research programme into biological control of the weed, given several different future scenarios. These scenarios were high herbicide prices, a price premium for lamb raised without chemical herbicides, and development of herbicide resistance. The model results were used to estimate national impacts. If the only change in the agricultural sector was the cost of the biocontrol to the nation＇s farmers, the research programme to find an effective biocontrol agent had little economic impact. If other factors changed, such as the price of petroleum or levels of herbicide resistance in the weed. the model＇s results suggested that intensive sheep farming could grow or shrink by as much as NZ$219 million dollars over five years. In the latter case, having an alternative control method reduced potential losses and increased potential gains, resulting in a net benefit of between NZ$81 million and NZ$153 million. This work extended prior research in several ways. First. Californian thistle reproduces via root buds, which affected the modelling of weed behaviour. Secondly, the model allowed optimistation over continuous levels of weed control for two different methods. Thirdly, the model accounted for both weed control and damage to nitrogen-fixing clover from herbicide use. Finally, the research investigated optimal weed control in several different alternative future states.
