ObjectiveThe research focuses on developing modeling and evaluation methodologies for an animal model exhibiting spleen deficiency and dampness excess syndrome， with the aim of standardizing such animal models for future reference. MethodsBy conducting a literature search on animal models of spleen deficiency and dampness excess syndrome， relevant publications meeting inclusion and exclusion criteria will be identified based on publication date， data source， types of diseases involved， animal characteristics， modeling methods， modeling duration， macroscopic syndrome assessment indicators， macroscopic quantification indicators， laboratory testing parameters， intervention approaches， positive controls and application context. A database will be established to facilitate the extraction of this information for quantitative analysis， statistical evaluation， and visual representation. ResultsA total of 137 literature articles meeting the standards have been included in the research. The primary animal species used in animal models of spleen deficiency and dampness excess are SD rats. Modeling methods include single-factor， dual-factor composite， and triple-factor composite methods， with various models widely applied in validation of pharmacological effects and mechanistic explorations. Evaluation indices of animal models for spleen deficiency and dampness excess primarily consist of macroscopic syndrome evaluation indicators and macroscopic quantitative indicators. Laboratory testing indicators are mostly related to research areas such as fluid metabolism and gastrointestinal function. The most commonly studied herbal formulas currently include Shenling Baizhu San and Pingwei San， with natural recovery and the use of the western medicine metronidazole as the most frequently used positive controls. ConclusionThe application of animal models for spleen deficiency and dampness excess is gradually increasing， with various modeling methods already simulating the typical characteristics of this syndrome pattern. However， there are still many areas that are worth contemplating and improving. This study aims to provide reference and ideas for the standardization of symptom names in animal models of spleen deficiency and dampness excess， as well as for the improvement of model construction and evaluation systems.

Objective:To explore the ventilation strategy of using pressure controlled ventilation-volume guaranteed (PCV-VG) mode combined with personalized positive end expiratory pressure (PEEP) during surgery, and its impact on oxygenation function and incidence of postoperative pulmonary complications (PPCs) in patients undergoing brain tumor surgery.Methods:Sixty patients who underwent elective brain tumor surgery at the Linyi People′s Hospital from January 2023 to June 2023 were selected. The patients were randomly divided into PCV-VG ventilation mode group (T group) and volume controlled ventilation (VCV) mode group (C group) using a random number table method, with 30 patients in each group. One patient was excluded from group T due to changes in the condition, and 29 patients were actually included. Group T adopted PCV-VG ventilation mode and searched for the maximum dynamic lung compliance (Cdyn) by titrating PEEP. The PEEP corresponding to the maximum Cdyn value was the optimal PEEP, which was maintained until the end of mechanical ventilation. Group C adopted a ventilation mode of VCV plus 5 cmH 2O fixed value PEEP. All patients underwent arterial blood gas analysis before anesthesia induction (T 1), 15 minutes after setting ventilation mode (T 2), and 15 minutes after extubation (T 3), recording arterial oxygen partial pressure (PaO 2), carbon dioxide partial pressure (PaCO 2), lactate (Lac), and blood glucose (Glu), and calculating oxygenation index (PaO 2/FiO 2). The levels of white blood cells (WBC), C-reactive protein (CRP), and procalcitonin (PCT) were recorded before and 72 hours after surgery. The incidence of postoperative PPCs at 72 hours was observed. Results:There was a statistically significant difference in the grouping effect and time effect of PaO 2 and PaCO 2 between group C and group T (all P<0.05), while there was no statistically significant difference in the interaction effect (all P>0.05); The differences in grouping effects, time effects, and interaction effects of PaO 2/FiO 2 between group C and group T were statistically significant (all P<0.05); The average value of the optimized PEEP obtained by T-group titration was 7.48 cmH 2O, corresponding to an average platform pressure (Pplat) of 14.90 cmH 2O, and an average value of 53.37 ml/cmH 2O corresponding to the maximum Cdyn value. Compared with the Pplat and Cdyn corresponding to the fixed value of 5 cmH 2O PEEP in Group C, the Pplat corresponding to the optimized PEEP in Group T was lower than that in Group C ( P<0.05), and the Cdyn was higher than that in group C ( P<0.05). The CRP level and incidence of PPCs in group T after 72 hours of surgery were significantly lower than those in group C (all P<0.05). Conclusions:Compared with VCV, the ventilation mode of PCV-VG combined with personalized PEEP can improve intraoperative lung ventilation and oxygenation function in patients with brain tumors, reduce the occurrence of pulmonary inflammation 72 hours after surgery, and lower the incidence of PPCs.

OBJECTIVE：To standardize and optim ize the clinical use of Trastuzumab for injection ，and to provide reference for rational use of drugs in the patients. METHODS ：The pharmacy intravenous admixture service （PIVAS）in our hospital took the lead in communication and coordination with financial ，information，medical insurance departments as well as clinicians and nurses，to set up dispensing ，charging and reimbursement mode by dose of trastuzumab. Under that ，doctors could give orders according to the clinical dosage of patients ；PIVAS dispenses drugs according to the actual dose ；the drugs were shared among patients；the charge and reimbursement of drugs are carried out according to the actual dose of patients. At the same time ，the questionnaire survey was conducted among 60 patients about the medical experience and cost savings before and after the implementation of the mode . RESULTS ：The questionnaire survey showed that in terms of solving the potential safety problems of trastuzumab and the inconvenience of patients ’medical treatment ，the solution rate of the mode was 100％；in terms of improving patients’feeling of seeking medical treatment and helping treatment ，the improvement rate was 100％；in terms of saving patients ’ treatment costs ，most（80％）of the patients thought that it could save less than 500 yuan each time ，and rest of the patients thought that it could save more than 500 yuan each time. CONCLUSIONS ：The mode of dispensing ，charging and reimbursement of Trastuzumab for injection in our hospital has solved the problems of drug waste ，occupational injury and inconvenient preservation in clinical use ，and has played a good role in drug safety ，cost saving and patient convenience.

Objective: To determine the effect of gut microbiota on a rat model of post-traumatic stress disorder(PTSD)and explore the correlation of gut microbiota with behavior and neurotransmitters.Methods: We established a single prolonged stress(SPS)model to examine the pathogenesis of PTSD on rat behavior,gut microbiota,and neurotransmitter levels.Rats were separated into control and model groups,and neurotransmitter levels were measured using enzyme linked immunosorbent assay.Then,16 S rRNA sequencing was used to compare the gut microbiota between the control and model groups.Results: Compared with those in the control group,freezing time significantly increased,while number of standing upright,crossing frequency,time spent in the central arena,and total distance traveled were significantly reduced in the model group after exposure to SPS(all P<.05).Meanwhile,serotonin,or 5-hydroxytryptamine,levels in the brain in the model group were significantly lower than those the control group(P=.0332).In addition,changes were observed in the gut microbiota diversity and relative abundances of bacterial phyla,orders,families,and genera in the model group.Especially,changes in Firmicutes,Bacteroidetes,Cyanobacteria,and Proteobacteria levels were most pronounced after SPS exposure.Correlation analysis showed that the strongest positive correlation was found between Bac-teroidaceae and 5-HT(P =.0009).Moreover,RF32 abundance was the most negatively related to 5-HT(P=.0009),crossing frequency(P=.0007),and total distance(P=.0003).Conclusion: Our results suggest that SPS model rats showed differences in behavior,neurotransmitter levels,and gut microbiota with control rats.Moreover,Firmicutes,Bacteroidetes,Cyanobacteria,and Proteobacteria were most relevant to the exhibited fear-like and anxiety-like behaviors and significant serotonin content reduction in SPS model rats.

Objective To explore the histological basis of diffusion tensor tractography (DTT)fiber tracer images of benign prostatic hyperplasia (BPH)and prostate cancer (PCa).Methods Sixty-eight patients with PCa and sixty patients with BPH confirmed by pathology were recruited for this study.Conventional MRI and DTI examinations were performed.The original DTI data were processed at the AW4.5 workstation.After pos-t processed,FA and ADC values were recorded,DTT was plotted.Fiber bundle travel was observed and scored by two senior radiologists.The BPH and PCa specimens were stained with Masson fibers,and the diameter and angle of the fiber bundles were recorded.Results The FA values of BPH and PCa were 0.22±0.05 and 0.47±0.01 ,respectively.ADC values of BPH and PCa were (1.31 ±0.27)×10－3 mm2/s and (0.6 1 ±0.09)× 10－3 mm2/s,respectively.The differences in ADC and FA values among BPH and PCa were statistically significant (P＜0.05).DTT showeded that the fibers of BPH were dense and long,while the fibers of PCa were messy and short.The diameter and angle of collagen fibers and smooth muscle fibers for BPH were both larger than those for PCa,but only the difference between the diameter of smooth muscle fibers was statistically significant (P＜0.05).Conclusion There are significant differences between BPH and PCa in DTT images,which is consistent with the characteristics of fiber structure.DTI fiber bundle can reflect the differences of fiber structure between BPH and PCa.

Objective: To understand the factors affecting the compliance of blood glucose monitoring in patients with type 2 diabetes in rural areas, and to provide evidence for improving the compliance of patients with blood glucose monitoring. Methods: A method of phenomenological study in qualitative research was conducted to conduct deep semi-structured interviews on 43 patients with poor blood glucose compliance in type 2 diabetes in rural areas, and to analyze the collected data. Results: Extracted five themes: bad experience affected compliance; lack of knowledge about blood glucose monitoring; economic and time was not sufficient; "long-term illness into a good doctor" overconfidence; social support uncertainty. Conclusions The status of blood glucose monitoring in rural type 2 diabetes patients is not optimistic. In order to improve the compliance of patients with blood glucose monitoring, nursing workers should pay attention to the mastery of blood glucose monitoring knowledge in rural type 2 diabetes patients, improve blood glucose monitoring methods and techniques, and give full play to the role of family doctors. Efforts to improve patient blood glucose monitoring compliance.

Objective To investigate and analyze TCM syndrome characteristics, impact factors and internal relationship among the factors of mental fatigue of university students. A preliminary understanding of mental fatigue situation of university students and prevent diseases was acquired in advance. Methods 100 students were randomly selected in Beijing University of Chinese Medicine, of whom 40 were undergraduate students and 60 were post-graduate students. Mental fatigue questionnaire was used to investigate mental fatigue situation for students, and TCM constitution scale was applied to collect TCM syndromes. A body energy survey was also conducted. Results In undergraduate and post-graduate students, the mental fatigue rate was relatively higher, both of them were over 50%of the total numbers, 57.5%(23/40)、61.7%(37/60) respectively. For the fatigue levels distribution in these two groups, the ratios of slight mental fatigue (undergraduate:52.5%;post-graduate:56.67%) were both higher than those of severe mental fatigue (undergraduate:5%;post-graduate:5%). In the undergraduate group, the top three biased constitutions among mental fatigue students were yang deficiency (7 out of 23:30.43%), qi deficiency (3 out of 23:13.04%) and dampness-heat (3 out of 23:13.04%). In the post-graduate group, the top three biased constitutions were yang deficiency (11 out of 37:29.73%), qi deficiency (6 out of 37: 16.22%) and dampness-heat (5 out of 37: 13.51%). Conclusion It is easier for university students with biased constitution to suffer from mental fatigue, mostly with yang deficiency, qi deficiency and dampness-heat constitution.

Objective To investigate the correlation between the types of constitution in TCM and the sleep status in the PLA Navy divers. Methods Eighty-nine PLA Navy divers who performed 10m diving professional training were selected. Constitution in TCM was classified and determined by the standardized standard Constitution in Chinese Medicine Questionnaire, sleep status was evaluated by the Pittsburgh Sleep Quality Index. Results 62.9% of Navy divers were the mild constitution in TCM. The eight kinds of the biased constitution in TCM are ranked with yang deficiency, phlegm-dampness, dampness-heat, qi deficiency, yin deficiency, blood stasis, qi stagnation and special intrinsic quality. Among 78 Navy divers with good sleep quality, there were 49 divers (72.1%) with the mild constitution in TCM and 19 (27.9%) with the biased constitution in TCM. Among 21 Navy divers with poor sleep quality, there were 7 divers (33.3%) with the mild constitution in TCM (accounting for) and 14 (66.7%) with the biased constitution in TCM. For Navy divers with poor sleep quality, the sleep quality scores were positive correlated with the blood stasis constitution in TCM (r=0.481,P<0.05). Conclusion Sleep status is correlated with the types of the constitution in TCM, and regulating constitution in TCM can improve sleep quality in PLA Navy divers.
