In recent years, social emergencies have occurred frequently, and the losses caused by society have become more and more serious. Effectively dealing with emergencies has aroused widespread concern in society, and responding to emergencies is the key to emergency decision-making. This paper summarizes the development and research status of big data emergency decision-making at home and abroad through the analysis and combing of related literatures at home and abroad, and puts forward the opportunities and challenges faced by big data emergency decision-making at present, and puts forward relevant development suggestions.

Eight adult (six male and two female) wild Qinling giant pandas (Ailuropoda melanoleuca qinlingensis) from China National Foping Nature Reserve were tracked, and their dental data collected and recorded from October 2010 to April 2014. Each panda had dental abnormalities of varying severity. Dental wear and fracture were the most common conditions. Absent teeth were common, with premolars missing most often. Mild caries were present in five molar teeth between two animals. Different degrees of dental plaque and calculus occurred in all animals but without severe periodontal disease. Two animals with severe dental abnormalities died due to intestinal problems. Large segments of bamboo were found in their intestinal tracts, and intestinal perforation and ulcers were evident, indicating dental abnormalities can be an important factor in the health of wild giant pandas and may lead to death. Further research with larger sample sizes of wild and captive giant pandas will be required to substantiate the relationship between dental abnormalities and mortality in giant pandas.

Objective To assess the effects and utility of dexmedetomidine combined with tiletamine and zolazepam (dexMTZ) to immobilize the wild giant panda. Study design Prospective clinical study. Animals Seven giant pandas ( Ailuropoda melanoleuca ), five males and two females, aged 7–20 years and weighing 69.2–132.9 kg. Methods Once an animal was located, prior data on the individual was reviewed and the panda’s previously estimated body weight was used to calculate the volumes of drugs to administer: dexmedetomidine (dexM; 8 μg kg -1 ; 0.5 mg mL -1 ) and tiletamine–zolazepam (TZ; 2 mg kg -1 ; 50 mg mL -1 ). The mixture was injected intramuscularly (IM) using the Dan-Inject pistol system. When the panda was immobilized, it was weighed, a physical examination was performed and a blood sample collected. Every 5 minutes, the heart rate (HR), respiratory rate ( f R ), rectal temperature (T), noninvasive systolic arterial pressure (SAP), capillary refill time (CRT), mucous membrane color and pulse quality were recorded. After all procedures had been completed, atipamezole (40 μg kg -1 ) was injected IM. Results A single injection of dexMTZ resulted in the immobilization of all seven giant pandas. The median (range) of anesthetic agents administered was dexM 8.4 μg kg -1 (7.3–10.5 μg kg -1 ) and TZ 2.0 mg kg -1 (1.8–2.5 mg kg -1 ). The palpebral reflex was lost 8 (7–12) minutes after the injection. Most of the physiological variables remained in the acceptable range. All procedures were completed in approximately 1 hour. Six out of the seven (85.7%) giant pandas recovered smoothly; one panda had a rough recovery. Conclusions and clinical relevance DexMTZ produced a satisfactory immobilization and a smooth recovery for wild giant pandas while allowing approximately 55 minutes for planned noninvasive procedures.
