Abstract
Fat emulsion is a drug commonly used clinically for parenteral nutrition support in critically ill patients.With the development of the pharmaceutical industry, fat emulsion has formed a variety of different formulations, among which different types of fat emulsion have their own metabolic and body energy supply characteristics, and the application indications are also different. In addition to providing the supply of nutrients, the role of fat emulsion in anti-toxicity, immune regulation, anti-inflammatory, anti-shock, cardiopulmonary resuscitation and other aspects has gradually been discovered. This article reviews the existing evidence-based medical evidence and expounds the mechanism and therapeutic role of fat emulsion in the treatment of critically ill patients with poisoning. Its value in the treatment of critically ill patients with poisoning was discussed, and some references were provided for the application of non-nutritional functions of fat emulsion in the future.

Abstract
Objective: To investigate theaccuracy of artificial intelligence sleep staging model in patients with habitual snoring and obstructive sleep apnea hypopnea syndrome (OSAHS) based on single-channel EEG collected from different locations of the head. Methods: The clinical data of 114 adults with habitual snoring and OSAHS who visited to the Sleep Medicine Center of Beijing Tongren Hospital from September 2020 to March of 2021 were analyzed retrospectively, including 93 males and 21 females, aging from 20 to 64 years old. Eighty-five adults with OSAHS and 29 subjects with habitual snoring were included. Sleep staging analysis was performed on the single lead EEG signals of different locations (FP2-M1, C4-M1, F3-M2, ROG-M1, O1-M2) using the deep learning segmentation model trained by previous data. Manual scoring results were used as the gold standard to analyze the consistency rate of results and the influence of different categories of disease. Results: EEG data in 124 747 30-second epochs were taken as the testing dataset. The model accuracy of distinguishing wake/sleep was 92.3%,92.6%,93.5%,89.2% and 83.0% respectively,based on EEG channel Fp2-M1, C4-M1, F3-M2, REOG-M1 or O1-M2. The mode accuracy of distinguishing wake/REM/NREM and wake/REM/N1-2/SWS , was 84.7% and 80.1% respectively based on channel Fp2-M1, which located in forehead skin. The AHI calculated based on total sleep time derived from the model and gold standard were 13.6[4.30,42.5] and 14.2[4.8,42.7], respectively (Z=-2.477, P=0.013), and the kappa coefficient was 0.977. Conclusions: The autonomic sleep staging via a deep neural network model based on forehead single-channel EEG (Fp2-M1) has a good consistency in the identification sleep stage in a population with habitual snoring and OSAHS with different categories. The AHI calculated based on this model has high consistency with manual scoring.

Abstract
This review illustrates the distribution of tropane alkaloids within the families Solanaceae, Erythroxylaceae, Proteaceae, Euphorbiaceae, Rhizophoraceae, Convolvulaceae and Cruciferae. Whereas tropane alkaloids are characteristic of the genera Datura, Brugmansia (tree datura) and Duboisia of the Solanaceae, the distribution is more widespread with novel tropane derivatives in families not traditionally associated with these bases. The chemical nature of more recently discovered water-soluble calystegines and the di- and trimeric forms from the Convolvulaceae (e.g. schizanthines from Schizanthus spp.), truxillines from Bolivian coca leaves and moonines of Erythroxylum moonii are highlighted. Where possible and appropriate, links between the phytochemistry and taxonomy are discussed.

Abstract
The calcium-binding domain of the small subunit of porcine calpain (domain VI) has been expressed in Escherichia coli, purified, and crystallized in the presence of Ca(2+). Two crystal forms have been obtained by the vapor-diffusion method using PEG 6000 as the precipitant. Crystal form I, belonging to trigonal space group P3(1)21 (or P3(2)21) with cell dimensions a = b = 79.8, c = 57.08 A, alpha = beta = 90.0 and gamma, = 120.0 degrees diffracted to 2.8 A. The second crystal form diffracts to 1.8 A and belongs to monoclinic space group P2(1) with cell dimensions a = 50.1, b = 79.7, c = 57.1 A and beta = 91.2 degrees.

Abstract
The three dimensional structure of calcium-bound domain VI of porcine calpain has been determined to 1.9 A resolution. The crystal structure reveals five EF-hands, one more than previously suggested. There are two EF-hand pairs, one pair (EF1-EF2) displays an 'open' conformation and the other (EF3-EF4) a 'closed' conformation. Unusually, a calcium atom is found at the C-terminal end of the calcium binding loop of EF4. With two additional residues in the calcium binding loop, the fifth EF-hand (EF5) is in a 'closed' conformation. EF5 pairs up with the corresponding fifth EF-hand of a non-crystallographically related molecule. Considering the EF5's role in a homodimer formation of domain VI, we suggest a model for the assembly of heterodimeric calpain. The crystal structure of a Ca2+ bound domain VI-inhibitor (PD150606) complex has been refined to 2.1 A resolution. A possible mode for calpain inhibition is discussed.

Abstract
The Duboisia hybrid (D. leichhardtii x D. myoporoides) was regenerated from callus derived from shoot tips and young seeds on Murashige and Skoog (MS) medium containing 54μM 1-naphthalenacetic acid (NAA) and 1μM 6-benzylaminopurine (BA). Callus derived from young seeds was superior to shoot tip callus. Buds were induced from callus on MS medium supplemented with 22μM BA. The buds formed shoots when transferred to MS medium with 5 μM BA and 0.5μM NAA. Shoots were induced to form roots when placed on MS medium containing 25 μM indolebutyric acid (IBA). Plantlets so formed were transplanted and subsequently planted out in the open. Approximately 6 months were required for the full regenerative process. Trees so formed have been grown for 3 years, reached a height of 3 metres and flowered and fruited normally.

Abstract
The orientation and position of the trypsin molecule in the complex crystal cell mung bean trypsin inhibitor Lys fragment (MBILF)-bovine trypsin (BTRY) have been successfully determined by molecular replacement method with the model of the refined bovine trypsin molecule. Starting from the BTRY coordinates which were oriented and located in the correct azimuth and position in the complex cell according to the result from rotation function and translation function, sim-weighted Fourier map with coefficients 2/Fo/-/Fc/ at 3.0 A resolution was calculated. Besides the electron density which is obviously attributed to itself, in the vicinity of the active site of BTRY the dense contour levels corresponding to the MBILF and and its boundary could be clearly seen in this map. The size of MBILF was approximately estimated at 15 x 15 x 25 A.

The single crystals of the complex were obtained by using the micro-still-setting method and the X-ray diffraction extended to 1.8A resolution. Its space group is P212121 with cell dimensions a = 62.9(1)A, b = 63.4(1)A and c = 69.7 (2)A. There is one complex molecule in a crystallographic asymmetric unit.

Abstract
Traumatic forequarter amputation is rare and extremely mutilating. A 21-year-old male factory worker who sustained a traumatic shoulder girdle amputation is described. The injury mechanism was traction from the machine's force combined with the compressive force on the sternoclavicular joint. The factors leading to survival from this injury include rapid transportation, prompt and effective resuscitation, including treatment of shock, and adequate surgical management. Recognition of the complications associated with retrosternoclavicular dislocation is emphasized.
