Animal model research on spleen and stomach diseases in traditional Chinese medicine （TCM） is of great significance for elucidating the nature of diseases and syndromes and for revealing the mechanisms of action of Chinese herbal medicinals. At present， studies on classical TCM syndrome models of spleen and stomach diseases mainly focus on spleen deficiency syndrome， liver constraint syndrome， and damp-heat syndrome. Model construction is mostly based on the etiological and pathophysiological characteristics of syndrome， and model evaluation primarily involves macroscopic manifestations and physicochemical indicators. This paper summarizes the current research status of animal models integrating disease and syndrome for seven common spleen and stomach diseases， including chronic gastritis and gastric precancerous lesions， gastroesophageal reflux disease， functional dyspepsia， inflammatory bowel disease， irritable bowel syndrome， functional constipation， and functional diarrhea. The modeling methods and characteristics of disease-syndrome combined animal models for each disease are analyzed. It is proposed that future research on disease-syndrome integration in spleen and stomach diseases should move toward syste-matic， precise， and integrative development， and that interdisciplinary and cross-disciplinary research approaches should be adopted to enhance the predictive value and application efficiency of disease-syndrome combined animal models.

This paper summarizes Professor CUI Yinglin's clinical experience in treating pediatric mitochondrial encephalomyopathy based on the original qi theory. It is proposed that original qi depletion is the core pathogenesis， and the fundamental therapeutic principle is consolidating the root and replenishing original qi. Clinically， the disease is classified into four syndrome types， including insufficiency of kidney essence， spleen qi depletion， liver-kidney yin deficiency， and original qi constraint and stagnation accompanied by phlegm-stasis obstructing the collaterals. Correspondingly， self-formulated Gujing Yiyuan Decoction （固精益元汤） can be used to tonify the kidney and replenish essence， reinforce and strengthen original qi. Modified Yiyuan Decoction （益元汤） is used to fortify the spleen and supplement qi， consolidate the root and replenish original qi. Modified Da Bu Yuan Decoction （大补元煎） is employed to nourish the liver and kidney， and replenish original qi. Self-formulated Huatan Quyu Formula （化痰祛瘀方） is used to supplement qi and activating blood， resolve phlegm and unblocking the collaterals. Medication is flexibly adjusted according to syndrome differentiation， with simultaneous attention to the functional balance of the zang-fu （脏腑） organs and the harmony of qi， blood， yin， and yang， which may provide useful guidance for the clinical treatment of pediatric mitochondrial encephalomyopathy.

ObjectiveTo meet the requirements of Good Laboratory Practice (GLP), Sichuan Institute for Drug Control (Sichuan Testing Center of Medical Devices, Sichuan Institute of Musk Deer Breeding) Safety Evaluation Center (hereinafter referred to as the center) conducts a targeted validation study to address the lack of supporting data for the specified validity periods of disinfectants, feed, and bedding during their use in laboratory animal facilities. The study summarizes practical experience in material management and provides a scientific basis for the standardized management of materials in the facility. MethodsUnder the routine operating conditions of the laboratory animal facility at the center, the disinfection efficacy of four commonly used disinfectants was confirmed using the quantitative suspension kill test, with the disinfectants tested on day 0, day 7, and at 1, 2, and 3 months after preparation and after opening; for laboratory animal feed, nutritional components, chemical contaminants, and microbial indicators were tested 7 days after opening; microbial indicators of laboratory animal corncob bedding were tested after storage for 7 days following opening and sterilization. ResultsUnder the GLP management system of our center, the disinfection efficacy log reduction values of prepared 0.04% sodium hypochlorite solution, 0.1% didecyldimethylammonium bromide solution, and 0.2% benzalkonium bromide solution were all ≥5 on days 0 and 7. The log reduction values of opened 75% ethanol were ≥5 on days 0 and 7 and at 1, 2, and 3 months after opening. All disinfectants were therefore qualified and effective. Compared with the factory inspection data, the nutritional components, chemical contaminants, and microbial indicators of SPF-grade rat and mouse maintenance feed, SPF-grade guinea pig growth and reproduction feed, conventional-grade guinea pig growth and reproduction feed, rabbit maintenance feed, and dog maintenance feed showed a slight overall downward trend but no significant differences 7 days after opening. The microbial indicators of specialized corncob bedding for SPF-grade laboratory animals stored for 7 days after opening and conventional-grade corncob bedding stored for 7 days after sterilization showed no significant fluctuations. All indicators still met the relevant requirements of GB/T 14924.2—2001 Laboratory Animals—Hygienic Standard for Formula Feeds and GB 14924.3—2010 Laboratory Animals—Nutrients for Formula Feeds. ConclusionBased on practical experience in managing the center's GLP laboratory animal facility and validation of core quality indicators, the specified validity periods of disinfectants, feed, and bedding meet the quality requirements, providing a practical reference for the standardized management of laboratory animal facilities.

Objective:To evaluate the effectiveness of anti-G straining maneuver (AGSM) in pilots by surface electromyography (sEMG), and to explore the relationships between characteristics of sEMG and anti-G endurance in pilots.Methods:Thirty-eight male high-performance fighter pilots who completed the human centrifuge test at the Air Force Medical Center were selected. Among them, 25 completed the 8.0 G for 10 s anti-G endurance test and 13 completed the 9.0 G for 10 s anti-G endurance test. The sEMG tester was used to keep track of the changes of sEMG in rectus abdominis, rectus femoris, anterior tibial and gastrocnemius muscles while pilots were engaged in AGSM. The anti-G endurance was evaluated according to the changes of visual fields and consciousness. The pilots were divided into 3 groups: the good vision and consciousness group, peripheral visual field narrowing group and endurance endpoint group. The differences in the integral electromyogram (iEMG), mean power frequency (MPF) and muscle input rates between the 3 groups were investigated.Results:A total of 25 pilots completed the 8.0 G for 10 s anti-G endurance test. Among them, 8 (32.0%) were in the good vision and consciousness group, 13 (52.0%) in the peripheral visual field narrowing group and 4 (16.0%) reached the endurance endpoint. Among the 13 pilots who completed the 9.0 G for 10 s anti-G endurance test, 3 (23.1%) were in the good vision and consciousness group, 6 (46.1%) in the peripheral visual field narrowing group, and 4 (30.8%) in the endurance endpoint group. The results of sEMG showed that the iEMG values of the anterior tibialis muscle in pilots under the 9.0 G for 10 s load were significantly different across endurance groups ( H=7.54, P=0.023), and that the iEMG values of the tibialis anterior muscle in the good vision and consciousness group were higher than those in the endurance endpoint group ( P=0.036). The negative slopes of MPF for the rectus abdominis, rectus femoris, anterior tibialis, and gastrocnemius muscles were higher in the good vision and consciousness group than in the other 2 groups, but the differences were not statistically significant ( P>0.05). During the 8.0 G for 10 s anti-G endurance test, there were significant differences in lower limb muscle contribution rates between the 3 groups ( F=4.19, P=0.029). The endurance endpoint group exhibited a lower contribution rate than the good vision and consciousness group ( P=0.025). During the 9.0 G for 10 s anti-G endurance test, there were significant differences in tibialis anterior muscle contribution rates between the 3 groups ( F=4.16, P=0.049). The endurance endpoint group demonstrated a lower contribution rate than the good vision and consciousness group ( P=0.049). Conclusions:The full and balanced activation of abdominal muscles and lower limb muscles, especially the effective mobilization of calf muscles, plays a pivotal role in improving pilots′ AGSM efficiency in high G environments.

Objective:To find out whether the performance of a China-made high performance human centrifuge can satisfy the need of high G training by conducting physiological experiments.Methods:The dynamic physical performance of the anti-G equipment with the human centrifuge was tested before 5 subjects underwent the gradual-onset rate (GOR) run and rapid onset rate (ROR) run experiments. The G onset rate of GOR was 0.1 G/s. The relaxed G-tolerance under GOR (GOR tolerance 1) and the anti-G straining maneuver aided G-tolerance under GOR (GOR tolerance 2) were tested respectively. The G onset rate of ROR was 3 G/s, and the closed-loop mode and pre-programed mode were employed respectively. The closed-loop mode involved 5 G 10 s and 8 G 10 s, where the subjects were required to manipulate the joystick to ensure that the real-time curve of the load matched the target curve. In the pre-programmed mode, the subjects were exposed to 8 G 10 s passively, without any operation requirements. A subjective evaluation form was filled out by subjects after the experiments, in which the 14 indexes for evaluation were about the gondola facilities and environment, running processes, medical monitoring and overall assessment.Results:Both the oxygen mask and anti-G suit achieved full pressurization within 2.0 s. The GOR tolerance 1 was [4.0(3.8, 4.6)] G while the GOR tolerance 2 was (6.2±0.5) G, suggesting a statistically significant difference ( Z=-2.63, P=0.008). The HP anti-G straining maneuver effect was (2.0±0.6) G. All the 5 subjects finished the 5 G 10 s experiment in a closed-loop mode. Three of them attempted 8 G 10 s in the closed-loop mode (1 subject achieved only 7.6 G peak acceleration, and the other 2 achieved full 8 G 10 s exposure), while the remaining 2 completed the 8 G 10 s in the pre-programmed mode. In the closed-loop mode, it was found that the stick force was too strong, the guiding G and real time G curve were not easy to distinguish for some of the subjects because the curve colors were similar, and that the subjects could not see the G curves clearly in case of a grayout. Both seat comfort and the voice quality of communication got the highest subjective assessment score [5.0(4.0, 5.0)] while the sensation of tumble got the lowest score (2.8±0.8). The median or mean scores of other subjective evaluation indexes ranged from 3.0 to 4.6 points. The overall score of subjective assessment was [4.0(3.5, 4.0)] points. Conclusions:The China-made high performance human centrifuge can meet the requirements of 8.0 G high G training, which can be made more effective and comfortable if the strong stick force and feeling of tumble during stop running are overcome.
