ObjectiveTo study the clinical characteristics and influencing factors of rheumatoid arthritis （RA） in the patients with cold dampness obstruction syndrome. MethodsThe RA patients treated in the Department of Traditional Chinese Medicine and Rheumatology of the China-Japan Friendship Hospital from August 2022 to June 2024 were selected. The demographic information， clinical data， laboratory test results， and traditional Chinese medicine （TCM） symptom information were collected for syndrome differentiation， on the basis of which the characteristics and influencing factors of cold dampness obstruction syndrome were analyzed. ResultsA total of 258 RA patients were selected in this study， including 88 （34.1%） patients with cold dampness obstruction syndrome， 53 （20.5%） patients with dampness and heat obstruction syndrome， 31 （12.0%） patients with wind dampness obstruction syndrome， 29 （11.2%） patients with liver-kidney deficiency syndrome， 19 （7.4%） patients with Qi-blood deficiency syndrome， 14 （5.4%） patients with phlegm-stasis obstruction syndrome， 15 （5.8%） patients with stasis obstructing collateral syndrome and 9 （3.5%） patients with Qi-Yin deficiency syndrome. The patients were assigned into two groups of cold dampness obstruction syndrome and other syndromes. The group of cold dampness obstruction syndrome had lower joint fever， 28-tender joint count （TJC28）， and 28-joint disease activity score （DAS28）-C-reactive protein （CRP） and higher central sensitization， cold feeling of joints， fear of wind and cold， cold limbs， and abdominal distention than the group of other syndromes （P<0.05）. The binary logistic regression analysis showed that central sensitization （OR 5.749， 95%CI 2.116-15.616， P<0.001） and DAS28-CRP （OR 0.600， 95% CI 0.418-0.862， P=0.006） were the independent factors influencing cold dampness obstruction syndrome in RA. ConclusionCold dampness obstruction syndrome is a common syndrome in RA patients. It is associated with central sensitization， cold feeling of joints， abdominal distension and may be a clinical syndrome associated with central sensitization.

Objective: To evaluate the application of blood conservation measures in obstetric patients with different red blood cell transfusion volumes and to assess the impact of different transfusion volumes on postpartum outcomes. Methods: A retrospective investigation was conducted on 448 obstetric patients who received blood transfusions at the Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to December 2022. Patients were divided into four groups (1-2 units group, 3-4 units group, 5-6 units group, and >6 units group) based on the volumes of red blood cells (RBCs) transfused during and within 7 days after delivery. The maternal physiological indicators, pre- and postpartum laboratory test indicators, obstetric complications, application of blood conservation measures, use of blood products, and postpartum outcomes were reviewed. The clinical characteristics, application of blood conservation measures, and their impact on postpartum outcomes were compared among different transfusion groups. Results: There were statistically significant differences in the multivariate logistic analysis of history of previous cesarean section (OR=1.781), eclampsia/pre-eclampsia/(OR=1.972) and postpartum blood loss>1 000 mL（OR=1.699）(P<0.05) among different transfusion groups. In terms of blood conservation measures, the more RBCs transfused, the higher the rate of mothers receiving blood conservation measures such as balloon occlusion, arterial ligation, autologous blood transfusion with a cell saver, and hysterectomy. With the increase in the volume of RBCs transfusion, the demand for fresh frozen plasma（FFP）, cryoprecipitate, and platelet transfusions also increased. The hospitalization days for the four groups of parturients were 6.0 (4.0-9.0), 7.5 (5.0-14.8), 7.0 (4.5-13.0) and 11.0 (9.0-20.5), respectively (P<0.05) and the rates of ICU transfer were 2.0% (5/250), 9.4% (12/128),18.2% (6/33) and 51.4% (19/37), respectively (P<0.05). Both increased significantly with the increase in the volume of RBCs transfusion, and the differences between groups were statistically significant. Conclusion: Parturients who received higher volume of RBCs had multiple risks factors for bleeding before childbirth, had higher postpartum blood loss, and had a higher rate of application of various blood conservation measures. In addition, an increase in the volume of RBCs transfusion may have adverse effects on postpartum recovery.

Objective To evaluate the effects of ketamine combined with sufentanil on postoperative analgesia and depression in patients undergoing hip arthroplasty.Methods A total of 60 patients who underwent elective hip arthroplasty were selected and divided into the S group,the SK1 group and the SK2 group according to the patient-controlled intravenous analgesia regimen,with 20 cases in each group.Patients in the S group were received 2 μg/kg of sufentanil for postoperative analgesia,patients in the SK1 group were received 1 mg/kg of esketamine and 2 μg/kg of sufentanil for postoperative analgesia,and patients in the SK2 group were received 2 mg/kg of esketamine and 2 μg/kg of sufentanil for postoperative analgesia.At 1,4,24,and 48 hours after surgery,the analgesic effect of patients was evaluated using the numeric rating scale(NRS),and the sedation effect of patients was evaluated using the Ramsay sedation score.Depression of patients before and 48 hours after surgery was assessed by self-rating depression scale(SDS).The adverse reactions such as nausea and vomiting,dizziness and headache,respiratory depression,and mental symptoms within 48 hours after surgery of patients were recorded.Results The NRS scores 1,4,and 24 hours after surgery of patients in the SK1 group and the SK2 group were lower than those in the S group(P<0.05);there was no statistically significant difference in the NRS scores 48 hours after surgery of patients among the three groups(P>0.05);there was no statistically significant difference in the NRS scores at different postoperative points of patients between the SK1 and SK2 groups(P>0.05).The SDS scores 48 hours after surgery of patients in each group were lower than those before surgery(P<0.05).There was no statistically significant difference in the Ramsay scores at different postoperative points of patients among the three groups(P>0.05).The incidence of adverse reactions 48 hours after surgery in the SK2 group was higher than those in the S group and the SK1 group(P<0.05).Conclusion Using 1 mg/kg of esketamine combined with 2 μg/kg of sufentanil after hip arthroplasty has a good analgesic effect without obvious increase of adverse reactions or significant effect on improving depression of patients.

ObjectiveTo conduct a systematic comparative study on wild and cultivated Codonopsis pilosula（CP） from three aspects， including characters， microscopy， and contents of primary and secondary metabolites. MethodWild and cultivated CP samples were collected， their characters were measured using vernier caliper， tape measure and balance， the paraffin sections were stained with safranin-fixed green dyeing， and their microstructure were observed under the optical microscope. The content of alcohol-soluble extracts in wild and cultivated CP was determined according to the method for determination of extract under CP in the 2020 edition of Chinese Pharmacopoeia， the starch content was determined by anthrone colorimetry， the content of total polysaccharides was determined by kit method， Fiber analyzer was used to determine the content of fiber components， and ultra performance liquid chromatography（UPLC） was used to determine the content of monosaccharides， disaccharides and some secondary metabolites. Multivariate statistical analysis methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were employed to screen key differential components between wild and cultivated CP on the basis of variable importance in the projection（VIP） value>1 and P<0.05. ResultIn terms of morphological characteristics， the "lion's head-like" shape， longitudinal wrinkles， and circumferential wrinkles below the root cap of wild CP were more pronounced in wild CP compared to the cultivated ones. Regarding transverse sectional features， wild CP had more fissures on the outer side of the cortex and a larger duramen. Under microscopic examination， wild CP had more stone cells， a larger proportion of xylem， and the presence of cork cells arranged in rings in the xylem， while cultivated CP has a larger proportion of phloem， smaller vessel diameters， and a more loosely arranged vascular system. In terms of primary metabolites， the contents of 45% ethanol-soluble extract and total polysaccharides in cultivated CP were significantly higher than those in the wild ones（P<0.05）， the contents of lignin， hemicellulose， cellulose， fructose and glucose in wild CP were significantly higher than those in the cultivated ones（P<0.05）， while sucrose content in the cultivated CP was significantly higher than that in the wild ones（P<0.05）. Concerning secondary metabolites， the contents of tryptophan and tangshenoside Ⅰ in cultivated CP were significantly higher than those in the wild ones（P<0.05）， whereas the contents of lobetyolinin， lobetyol and atractylenolide Ⅲ in wild CP were significantly higher than those in the cultivated ones（P<0.05）. ConclusionThere are significant differences between wild and cultivated CP in terms of morphological characteristics， microscopic features and chemical composition. Glucose， fructose， sucrose， tangshenoside Ⅰ， tryptophan and cellulose components are the key differential components between wild and cultivated CP. Wild CP contains more polyacetylenes and fructose， whereas cultivated CP has higher levels of tangshenoside Ⅰ and sucrose， with noticeably lower cellulose content. These distinctions may be related to their growth conditions， growth years and cultivation techniques. Based on the results of this study， it is recommended to increase polyacetylenes and the content ratio of fructose to sucrose as an indicators to characterize different production methods of CP， in order to guide the high-quality production of CP.

Objective To investigate the expression of Nanog and its regulatory relationship with MMP-2/MMP-9 proteins in esophageal squamous cell carcinoma(ESCC).Methods We detected Nanog and MMP-2/MMP-9 protein expressions in 127 ESCC tissues and 82 adjacent normal tissues using immunohistochemistry and explored their correlations with the clinicopathological parameters and prognosis of the patients.GEO database was utilized to analyze the pathways enriched with the stemness-related molecules including Nanog,and TIMER online tool was used to analyze the correlations among TβR1,MMP-2,and MMP-9 in esophageal cancer.Results Nanog and MMP-2/MMP-9 proteins were significantly upregulated in ESCC tissues and positively intercorrelated.Their expression levels were closely correlated with infiltration depth and lymph node metastasis of ESCC but not with age,gender,or tumor differentiation.The patients with high expressions of Nanog and MMP-2/MMP-9 had significantly shorter survival time.Bioinformatics analysis showed enrichment of stemness-associated molecules in the TGF-β signaling pathway,and the expressions of MMP-2/MMP-9 and TβR1 were positively correlated.In cultured ESCC cells,Nanog knockdown significantly decreased the expression of TβR1,p-Smad2/3,MMP-2,and MMP-9 and strongly inhibited cell migration.Conclusion The high expressions of Nanog,MMP-2,and MMP-9,which are positively correlated,are closely related with invasion depth,lymph node metastasis,and prognosis of ESCC.Nanog regulates the expressions of MMP-2/MMP-9 proteins through the TGF-β signaling pathway,and its high expression promotes migration of ESCC cells.

Objective To explore the current status of posttraumatic growth (PTG) among nurses at psychiatric department and analyze its latent profiles and population characteristics. Methods A total of 357 nurses from psychiatric departments of five tertiary Grade A hospitals were selected as the research subjects using the convenience sampling method. The PTG and professional quality of life were studied using the Posttraumatic Growth Inventory and the Chinese version of the Compassion Fatigue Scale. Results The PTG score of the nurses was (56.6±23.2). The scores of compassion satisfaction, burnout, and secondary traumatic stress among nurses were (32.6±7.2), (26.9±5.9), and (26.0±5.4), respectively. The result of potential profile analysis showed that the nurses could be divided into three latent profiles based on PTG levels: low PTG group (34.4%), moderate PTG group (44.0%), and high PTG group (21.6%). The results of multinomial logistic regression analysis showed that the nurses who slept 7-8 hours per day were at higher risk of being in the high PTG group compared with those who slept more than eight hours per day (P<0.05). Psychiatric nurses who took regular exercise were at higher risk of being in the high PTG group compared with those who took irregular exercise (P<0.05). The nurses who had high job satisfaction scores were at higher risk of being in the high PTG group compared with those who had low job satisfaction scores (P<0.01). The nurses with higher compassion satisfaction scores increased the risk of being in the high PTG group compared with those with lower compassion satisfaction scores (P<0.01). The nurses with higher burnout scores increased the risk of being in the low PTG group compared with those with lower burnout scores (P<0.01). Conclusion The PTG characteristics of the nurses exhibit heterogeneity and can be categorized into three distinct profiles. Sleep duration, regular exercise, job satisfaction, compassion satisfaction, and burnout are influencing factors for the PTG latent profiles of nurses working at psychiatric department.
