Efficacy of borneol-gypsum in skin regeneration and pain control in toxic epidermal necrolysis: A case report.

BACKGROUND: Toxic epidermal necrolysis (TEN) is a life-threatening dermatological emergency mainly induced by drug hypersensitivity reactions. Standard management includes discontinuation of culprit drug and application of immunomodulatory therapy. However, mortality remains high due to complications like septic shock and multiorgan failures. Innovative approaches for skin care are crucial. This report introduces borneol-gypsum, a traditional Chinese drug but a novel dressing serving as an adjuvant of TEN therapy, might significantly improve skin conditions and patient outcomes in TEN. CASE SUMMARY: A 38-year-old woman diagnosed with eosinophilic granulomatosis with polyangiitis experienced gangrenous complications and motor nerve involvement. After initial treatment of high-dose corticosteroids and cyclophosphamide, symptom of foot drop improved, absolute eosinophil counts decreased, while limb pain sustained. Duloxetine was added to alleviate her symptom. Subsequently, TEN developed. Additional topical application of borneol-gypsum dressing not only protected the skin lesions from infection but also significantly eased localized pain. This approach demonstrated its merit in TEN management by promoting skin healing and potentially reducing infection risks. CONCLUSION: Borneol-gypsum dressing is a promising adjuvant that could significantly improve TEN management, skin regeneration, and patient comfort.

[Evaluation of dental operating microscope and ultrasonic technique in root canal retreatment].

OBJECTIVE: To explore the use of dental operating microscope with ultrasonic instruments in root canal retreatment. METHODS: 164 root canals in 124 teeth of 111 patients who need root canal retreatment were treated under dental operating microscope (DOM) with ultrasonic instruments, then the success rates were calculated. RESULTS: Both 136 root canals with a success rate of 82.93% from 164 root canals and 103 teeth with a success rate of 83.06% from 124 teeth were managed successfully. The each category of the retreated teeth was 85.29% for calcified canals, 83.33% for canal subjected to resinifying therapy, 86.67% for misunderstood root canals, 100% for canals blocked by post, and 66.67% for both root canals blocked by instrument fragments and ledged. CONCLUSION: The use of microscope and ultrasonic instruments was proved to be an effective way in the root canal retreatment.

[Principles and methodology for ecological rehabilitation and security pattern design in key project construction].

Global ecological security becomes increasingly important with the intensive human activities. The function of ecological security is influenced by human activities, and in return, the efficiency of human activities will also be affected by the patterns of regional ecological security. Since the 1990s, China has initiated the construction of key projects "Yangtze Three Gorges Dam", "Qinghai-Tibet Railway", "West-to-East Gas Pipeline", "West-to-East Electricity Transmission" and "South-to-North Water Transfer" , etc. The interaction between these projects and regional ecological security has particularly attracted the attention of Chinese government. It is not only important for the regional environmental protection, but also of significance for the smoothly implementation of various projects aimed to develop an ecological rehabilitation system and to design a regional ecological security pattern. This paper made a systematic analysis on the types and characteristics of key project construction and their effects on the environment, and on the basis of this, brought forward the basic principles and methodology for ecological rehabilitation and security pattern design in this construction. It was considered that the following issues should be addressed in the implementation of a key project: 1) analysis and evaluation of current regional ecological environment, 2) evaluation of anthropogenic disturbances and their ecological risk, 3) regional ecological rehabilitation and security pattern design, 4) scenario analysis of environmental benefits of regional ecological security pattern, 5) re-optimization of regional ecological system framework, and 6) establishment of regional ecosystem management plan.

[The development of FSCLZLY--an ascites-ultrafiltration instrument].

It's known to all that the refractory ascites treatment has so far been a very difficult clinical problem. We have extracted much experience from the practical techniques used in the refractory ascites treatments of more than 1,000 cases, and have developed the ascites ultrafiltration & concentration therapeutic instrument--FSCLZLY-A. The clinical applications show that it is very effective. Its effective rate is about 72.08%. Therefore, it is a very useful and important medical device for refractory ascites, for the improvement of renal function, and for the prevention of the infection of abdominal cavity.
