Osteoarthritis （OA） and stroke are common clinical diseases that reduce patients' quality of life and place a burden on families and society. Ruyi Zhenbaowan， a classic prescription in Tibetan medicine， have the functions of clearing heat， awakening the brain and opening orifices， relaxing tendons and promoting meridian circulation， and eliminating yellow water. Clinically， they are used to treat osteoarthritis， post-stroke sequelae， neuropathic pain， and other related conditions. Modern pharmacological studies have demonstrated their anti-inflammatory， analgesic， and nerve-repairing effects. However， current research remains insufficient regarding the appropriate indications， timing， and efficacy of this medicine in treating relevant diseases. To enhance clinicians' understanding of this medicine and promote its standardized and rational clinical use， a panel of national experts， including clinical specialists， Tibetan medicine practitioners， pharmacologists， and methodologists， formulated this consensus based on clinical experience and evidence-based practice. The Cochrane systematic review framework， the Grading of Recommendations Assessment， Development and Evaluation （GRADE） system， and the nominal group method were employed to generate seven graded recommendations and 19 consensus-based suggestions. These recommendations clearly define the key points in the clinical application of Ruyi Zhenbaowan， including therapeutic indications， dosage and administration， treatment duration， and medication safety. The consensus specifically addresses the clinical efficacy， appropriate timing of administration， dosage strategies， treatment cycles， and combination medication strategies for treating osteoarthritis and stroke and provides an overview of safety considerations. The aim is to provide standardized guidance for hospitals and healthcare institutions nationwide to ensure the rational application of Ruyi Zhenbaowan in the treatment of osteoarthritis and stroke， reduce medication-related risks， and further leverage its clinical advantages. This consensus has been approved and issued by the China Association of Chinese Medicine， with the standard number GS/CACM 369-2024.

Objective To explore the influencing factors of hypothermia after extraperitoneal laparoscopic radical prostatectomy in prostate cancer patients over 80 years old,so as to improve the effectiveness of treatment.Methods The clinical data of 26 cases of prostate cancer patients over 80 years old who underwent extraperitoneal laparoscopic radical prostatectomy in Shanghai 411 hospital from January 2021 to December 2023 were analyzed retrospectively.The incidence of postoperative hypothermia was investigated.Univariate and multivariate Logistic regression analyses were used to analyze the related factors of postoperative hypothermia in elderly patients.Results The incidence of hypothermia was 61.54%(16/26).Univariate analysis indicated that body mass index(BMI),intraoperative thermal insulation,intraoperative infusion volume,operation time,and anesthesia time were related to the occurrence of postoperative hypothermia in elderly patients(all P<0.05).Multivariate Logistic regression analysis indicated that BMI≤24,intraoperative infusion volume>2 000 ml,anesthesia time>3 h and operation time>2.5 h were high risk factors for postoperative hypothermia in patients over 80 years old.Conclusion The independent influencing factors of hypothermia after extraperitoneal laparoscopic prostatectomy for selected prostate cancer patients over 80 years old are BMI,intraoperative infusion volume,duration of anesthesia,and operation time.These factors should be paid more attention during perioperative period in order to improve clinical safety.

Chronic obstructive pulmonary disease(COPD)has become a common chronic disease in the adult in recent years,and more attention has been gradually paid to its prevention and treatment.This paper reviewed the clinical studies about the effect of traditional Chinese medicine(TCM)exercise therapy on COPD,and indicated that TCM exercise therapy can improve the rehabilitation of COPD patients.TCM exercise therapies,such as Tai Chi,Wuqinxi,Baduanjin,and Liuzijue,have been shown to significantly improve lung function,inflammation levels,and exercise capacity in COPD patients in recent studies.Tai Chi significantly improves patient's respiratory problems although lung function indices are not changed.Liuzijue enhances the strength and endurance of respiratory muscles and limbs.Baduanjin helps to improve patient's cognitive and emotional states.Overall,TCM exercise therapy provides an effective rehabilitation option for COPD patients.However,more clinical controlled trials are needed to further confirm their effectiveness and to develop appropriate rehabilitation programs for COPD patients.

ObjectiveTo investigate the effects of spleen-Yin deficiency on gastrointestinal absorption， water metabolism and intestinal flora in rats with spleen-Yin deficiency syndrome. MethodA rat model of spleen-Yin deficiency syndrome was established by using the composite factors， including irregular meat and vegetable diet， weight-bearing fatigue swimming and gavage with warm-heat injury-Yin drugs. The changes of body weight， food intake， water intake and duration of swimming in the blank and model groups were observed. Hematoxylin-eosin（HE） staining was used to observe the histopathological damage of the stomach and colon. Urinary excretion rate of D-xylose was determined by phloroglucinol method. The content of gastrin（GAS） in serum was determined by enzyme-linked immunosorbent assay（ELISA）. The relative expression levels of vasoactive intestinal peptide（VIP）， aquaporin 3（AQP3） and AQP4 in gastric tissues were detected by Western blot. The relative mRNA expression levels of VIP， AQP3 and AQP4 in gastric tissues were detected by Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）， and the changes of intestinal flora were analyzed by 16S rDNA sequencing. ResultCompared with the blank group， the results of general physical signs showed that the body weight and food intake of rats in the model group were significantly decreased， the water intake was significantly increased（P<0.05， P<0.01）， and the duration of swimming was significantly decreased（P<0.01）. Pathological examination results showed that in the mucosa of gastric tissues of rats in the model group appeared to be misaligned， the mucosa of colonic tissues could be seen to be obviously thinned or mutilated， and the epithelial cells appeared to be necrotic or even exfoliated. Compared with the blank group， the urinary D-xylose excretion rate of rats in the model group was significantly decreased（P<0.01）， and the serum GAS content was significantly decreased（P<0.05）. Compared with the blank group， Western blot results showed that the relative expression level of VIP protein in gastric tissues of rats in the model group was significantly decreased， while the relative expression levels of AQP4 and AQP3 proteins were significantly increased（P<0.01）. Compared with the blank group， Real-time PCR results showed that the relative expression level of VIP mRNA in gastric tissues of rats in the model group was significantly decreased（P<0.01）， and the relative mRNA expression levels of AQP3 and AQP4 were significantly increased（P<0.05， P<0.01）. Compared with the blank group， the results of intestinal flora analysis showed that the number of operational taxonomic units（OTUs） and α-diversity increased and β-diversity decreased significantly in the model group， the abundance of Porphyromonadaceae was increased significantly， and the abundance of Oscillibacter_ruminantium was decreased significantly（P<0.05）. Spearman correlation analysis showed that Porphyromonadaceae was significantly positively correlated with AQP4 protein level， while Oscillibacter_ruminantium was significantly positively correlated with VIP protein level， and negatively correlated with AQP3 and AQP4 protein levels（P<0.05）. Linear discriminant analysis effect size（LEfSe） analysis results showed that there were significant differences in a variety of intestinal bacteria between groups， and the intestinal bacteria of the model group were significantly enriched in the phylum/order/family/genus of Elusimicrobia， Betaproteobacteria， Burkholderiales， Sutterellaceae and Parasutterella（P<0.05）. ConclusionSpleen-Yin deficiency syndrome can weaken the digestion and absorption capacity of gastrointestinal tract， and cause the disturbance of water metabolism and intestinal flora. AQP4， AQP3 and VIP protein levels of gastric mucosa are closely related to Porphyromonadaceae and Oscillibacter_ruminantium. And AQP4， AQP3 and VIP may be involved in the regulation of intestinal flora in order to affect the physiological function of spleen governing transportation and transformation.

Objective:To explore the feasibility and preliminary effectiveness of case-based learning (CBL) teaching based on network resources in standardized residency training for nuclear medicine.Methods:Open network resources of CBL curriculum (13 sessions in total) were used to perform the collective teaching of 21 residents who received training in our professional base, with a total of 61 person-times. The residents received the test on objective questions before class, immediately after class, and at 1 week after class (7-10 days) to assess the learning effect of residents at these time points, and an evaluation form of teaching effectiveness was used after each class to assess the teaching effect. SPSS 23.0 was used to perform a one-way analysis of variance.Results:As for the test score of objective questions, there were 61 valid scores before class, 61 valid scores immediately after class, and 51 valid scores at 1 week after class (7-10 days), with a mean score of (49.43±13.37), (84.43±14.44), and (80.88±10.04), respectively (with 100 points as the total score), which showed a significant difference ( F=105.80, P<0.01). As for the evaluation of teaching effectiveness, a total of 61 valid forms were received, and the results of "very satisfied, satisfied, fairly good, and dissatisfied" accounted for 34.4% (21/61), 52.5% (32/61), 9.84% (6/61), and 3.28% (2/61), respectively, with an overall satisfaction rate (very satisfied+satisfied) of 86.9% (53/61). Conclusion:It is feasible and effective to make full use of network resources to carry out CBL teaching in standardized residency training for nuclear medicine, which has achieved a good preliminary effect.

Patients with non-small cell lung cancer (NSCLC) are treated in a variety of ways. In addition to radiotherapy, chemotherapy and targeted therapy, breakthroughs have been made in immune checkpoint inhibitors, in particular, programmed cell death 1 (PD-1) and its ligand (PD-L1) inhibitors have achieved survival benefits for NSCLC patients, and some of them have been approved as first-line drugs by the US Food and Drug Administration. Currently, commonly used PD-L1 inhibitors are atezolizumab, durvalumab and avelumab. Combination therapies include combination with chemotherapy, anti-vascular endothelial growth factor drugs, molecular targeted therapy and immunotherapy.

It has been reported that ACE2 is the main host cell receptor of 2019-nCoV and plays a crucial role in the entry of virus into the cell to cause the final infection. To investigate the potential route of 2019-nCov infection on the mucosa of oral cavity, bulk RNA-seq profiles from two public databases including The Cancer Genome Atlas (TCGA) and Functional Annotation of The Mammalian Genome Cap Analysis of Gene Expression (FANTOM5 CAGE) dataset were collected. RNA-seq profiling data of 13 organ types with para-carcinoma normal tissues from TCGA and 14 organ types with normal tissues from FANTOM5 CAGE were analyzed in order to explore and validate the expression of ACE2 on the mucosa of oral cavity. Further, single-cell transcriptomes from an independent data generated in-house were used to identify and confirm the ACE2-expressing cell composition and proportion in oral cavity. The results demonstrated that the ACE2 expressed on the mucosa of oral cavity. Interestingly, this receptor was highly enriched in epithelial cells of tongue. Preliminarily, those findings have explained the basic mechanism that the oral cavity is a potentially high risk for 2019-nCoV infectious susceptibility and provided a piece of evidence for the future prevention strategy in dental clinical practice as well as daily life.

OBJECTIVE: To explore the effect of premenstrual syndrome( PMS) on the quality of life( QOL) of female medical staffs. METHODS: By convenient sampling method,1 007 female medical workers from three Grade A class 3 hospitals were selected as study subjects and investigated by PMS Scale,World Health Organization Quality of Life Assessment Instrument Brief Version,Simplified Coping Style Questionnaire and Social Support Rating Scale. RESULTS: The detection rate of PMS among medical staffs was 52. 0%,and the total score of QOL of PMS medical staffs was lower than that of non-PMS medical staffs [( 84. 3 ± 12. 4) vs( 90. 5 ± 11. 6),P < 0. 01]. The multivariate linear logistic regression analysis results showed that the PMS medical staffs who often stay up late,with higher degree of dysmenorrhea,higher job stress,lower positive coping style score,higher negative coping style score,and poor support have lower QOL( P < 0. 05). The coping style and social support of PMS medical staffs can directly affect the QOL. The social support can also indirectly affect the QOL through coping style. CONCLUSION: Coping style is a mediator of social support and QOL.Adopting coping style can improve the QOL of PMS medical staffs.

Objective To evaluate the effects of problem-based learning (PBL) teaching model in breast cancer medical imaging education based on multidisciplinary treatment (MDT). Methods The PBL teaching practice of breast cancer imaging based on MDT was carried out in the 192 clinical medicine students in Grade 2014 of Guangzhou Medical University. The students were randomly divided into four groups (group A, B, C and D) and each group was further divided into 1 to 5 teams, with 9 to 11 students in each team. The MDT teaching team consisted of clinical physicians in medical imaging, radiation oncology, surgery (specialized in breast tumor), and other disciplines. The formative assessment method was used to evaluate the teaching effects and the problems involved wereanalyzed. Results Firstly, with a full score of 100 points, the quantitative evaluation of each teaching team on the performance of students in PBL were (86.6±7.8), (87.1±8.1), (83.9±6.5), (88.1±4.5), and (85.1±8.2), respectively. No significant difference was found among each tutor team’s quantitative evaluation (F=1.014, P=0.388). Secondly, the whole posi-tive evaluation rate of students for tutors was 96.28%, with the highest and lowest positive rates as 98.36% and 94.08%, respectively. Significant difference was found among parts of the tutors ( χ2=10.554, P=0.032), specifically between team 1 and 5 (Z=2.245,P=0.025), 3 and 4 (Z=2.217,P=0.027) and 3 and 5 (Z=2.761,P=0.006) respectively. Lastly, the positive and negative evaluation rates of student's self-assessment were 87.33% and 12.67% respectively. Conclusion The effects of PBL based on MDT in breast cancer imaging teaching practice is encouraging, and the formative assessment method can objectively and effectively evalu-ate the effects of this kind of teaching model. However, the standards of evaluation still need to be further perfected and improved.
