Objective: To investigate the objective characteristics of tongue manifestation in different stages of damp-heat syndrome in diabetic kidney disease (DKD). Methods: A cross-sectional study enrolled 134 patients with DKD G3-5 stages who met the diagnostic criteria for damp-heat syndrome in DKD. The patients were treated at Dongzhimen Hospital, Beijing University of Chinese Medicine, from May 2023 to January 2024. The patients were divided into three groups: DKD G3, DKD G4, and DKD G5 stage, with 53, 33, and 48 patients in each group, respectively. Clinical general data (gender, age, and body mass index) and damp-heat syndrome scores were collected from the patients. The YZAI-02 traditional Chinese medicine (TCM) AI Tongue Image Acquisition Device was used to capture tongue images from these patients. The accompanying AI Open Platform for TCM Tongue Diagnosis of the device was used to analyze and extract tongue manifestation features, including objective data on tongue color, tongue quality, coating color, and coating texture. Clinical data and objective tongue manifestation characteristics were compared among patients with DKD G3-5 based on their DKD damp-heat syndrome status. Results: No statistically significant difference in gender or body mass index was observed among the three patient groups. The DKD G3 stage group had the highest age (P<0.05). The DKD G3 stage group had a lower score for symptoms of poor appetite and anorexia(P<0.05) than the DKD G5 group. No statistically significant difference was observed in damp-heat syndrome scores among the three groups. Compared with the DKD G5 stage group, the DKD G3 stage group showed a decreased proportion of pale color at the tip and edges of the tongue (P<0.05). The DKD G4 stage group exhibited an increased proportion of crimson at the root of the tongue, a decreased proportion of thick white tongue coating at the root, a decreased proportion of pale color at the tip and edges of the tongue, an increased hue value (indicating color tone) of the tongue color in the middle, an increased brightness value (indicating color lightness) of the tongue coating color in the middle, and an increased thickness of the tongue coating (P<0.05). No statistically significant difference was observed in other tongue color proportions, color chroma values, body characteristics, coating color proportions, coating color chroma values, and coating texture characteristics among the three groups. Conclusion Tongue features differ in different stages of DKD damp-heat syndrome in multiple dimensions, enabling the inference that during the DKD G5 stage, the degree of qi and blood deficiency in the kidneys, heart, lungs, liver, gallbladder, spleen, and stomach is prominent. Dampness is more likely to accumulate in the lower jiao, particularly in the kidneys, whereas heat evil in the spleen and stomach is the most severe. These insights provide novel ideas for the clinical treatment of DKD.

Objective To explore the construction of α-1,3-galactosyltransferase (GGTA1) gene-knockout (GTKO) Diannan miniature pigs and the kidney xenotransplantation from pigs to rhesus macaques, and to assess the effectiveness of GTKO pigs. Methods The GTKO Diannan miniature pigs were constructed using the CRISPR/Cas9 gene-editing system and somatic cell cloning technology. The phenotype of GTKO pigs was verified through polymerase chain reaction, Sanger sequencing and immunofluorescence staining. Flow cytometry was used to detect antigen-antibody (IgM) binding and complement-dependent cytotoxicity. Kidney xenotransplantation was performed from GTKO pigs to rhesus macaques. The humoral immunity, cellular immunity, coagulation and physiological indicators of the recipient monkeys were monitored. The function and pathological changes of the transplanted kidneys were analyzed using ultrasonography, hematoxylin-eosin staining, immunohistochemical staining and immunofluorescence staining. Results Single-guide RNA (sgRNA) targeting exon 4 of the GGTA1 gene in Diannan miniature pigs was designed. The pGL3-GGTA1-sgRNA1-GFP vector was transfected into fetal fibroblasts of Diannan miniature pigs. After puromycin selection, two cell clones, C59# and C89#, were identified as GGTA1 gene-knockout clones. These clones were expanded to form cell lines, which were used as donor cells for somatic cell nuclear transfer. The reconstructed embryos were transferred into the oviducts of trihybrid surrogate sows, resulting in 13 fetal pigs. Among them, fetuses F04 and F11 exhibited biallelic mutations in the GGTA1 gene, and F04 had a normal karyotype. Using this GTKO fetal pig for recloning and transferring the reconstructed embryos into the oviducts of trihybrid surrogate sows, seven surviving piglets were obtained, all of which did not express α-Gal epitope. The binding of IgM from the serum of rhesus monkey 20# to GTKO pig PBMC was reduced, and the survival rate of GTKO pig PBMC in the complement-dependent cytotoxicity assay was higher than that of wild-type pig. GTKO pig kidneys were harvested and perfused until completely white. After the left kidney of the recipient monkey was removed, the pig kidney was heterotopically transplanted. Following vascular anastomosis and blood flow restoration, the pig kidney rapidly turned pink without hyperacute rejection (HAR). Urine appeared in the ureter 6 minutes later, indicating successful kidney transplantation. The right kidney of the recipient was then removed. Seven days after transplantation, the transplanted kidney had good blood flow, the recipient monkey's serum creatinine level was stable, and serum potassium and cystatin C levels were effectively controlled, although they increased 10 days after transplantation. Seven days after transplantation, the levels of white blood cells, lymphocytes, monocytes and eosinophils in the recipient monkey increased, while platelet count and fibrinogen levels decreased. The activated partial thromboplastin time, thrombin time and prothrombin time remained relatively stable but later showed an upward trend. The recipient monkey survived for 10 days. At autopsy, the transplanted kidney was found to be congested, swollen and necrotic, with a small amount of IgG deposition in the renal tissue, and a large amount of IgM, complement C3c and C4d deposition, as well as CD68⁺ macrophage infiltration. Conclusions The kidneys of GTKO Diannan miniature pigs may maintain normal renal function for a certain period in rhesus macaques and effectively overcome HAR, confirming the effectiveness of GTKO pigs for xenotransplantation.

Objective:To comprehensively search the relevant literature on prone position-cardiopulmonary resuscitation (PP-CPR) in adults at home and abroad, analyze the content, summarize the evidence, and provide reference for clinical health care professionals.Methods:Systematic search of CNKI, China Biomedical Literature Service System (SinoMed), Wanfang Data, VIP database, PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochran Library, Web of Science, Scopus literature database and other Chinese and English databases was conducted. The search period was from inception to June 15 in 2024. The contents of PP-CPR from randomized controlled trial (RCT), non-RCT (prospective or retrospective), cohort studies and case reports were extracted and systematically analyzed. The search results were standardized by the method of scoping review.Results:A total of 523 articles were obtained through preliminary search, and 14 references and gray literature were retrieved, totaling 537 articles. After strict screening by two researchers, a total of 26 literatures were included, 3 were non-RCT and 23 were case reports, involving 12 countries, including 3 in Chinese, 19 in English, 2 in French, 1 in German, and 1 in Korean. Three non-RCT demonstrated that compared with standard cardiopulmonary resuscitation (CPR), PP-CPR could produce higher pressure, and provide good respiratory and circulatory support. A total of 25 adult patients were included in the 23 case reports, of which 17 reported total recovery time and 13 reported PP-CPR time ≤ 5 minutes, all of which recovered spontaneous circulation, indicating the effectiveness of PP-CPR technology. In terms of final outcome, 4 patients (16.0%) died and 21 patients (84.0%) survived, indicating that PP-CPR technology could provide timely blood circulation and improve clinical outcomes for prone cardiac arrest patients. Among the 11 patients who reported complications after resuscitation, no neurological damage was found in the short-term outcomes, indicating that PP-CPR technology had a certain level of safety.Conclusions:PP-CPR can provide timely blood circulation for patients with cardiac arrest who are unable to lie supine quickly, and win "golden time" for defibrillation and further treatment. In clinical practice, medical staff need to evaluate the emergency environment, the number of rescuers and the specific condition of the patient, and implement first aid as soon as possible, so as to reduce the time of no blood flow in the vital organs of patients with cardiac arrest in prone position, and improve the clinical prognosis.

Objective To explore the application of Chinese Drug-Related Problems Classification System in the pharmaceutical care of inpatients in neurology department.Methods A total of 222 inpatients admitted to the Department of Neurology of Affiliated Jinhua Hospital,Zhejiang University School of Medicine from March to June 2022 were selected as the study subjects,and the work records of clinical pharmacists were retrospectively analyzed.The drug-related problems(DRP)were sorted and analyzed according to the Chinese Drug-Related Problems Classification System.Binomial Logistic regression model was used to analyse the influencing factors of DRP.Results Among the 222 patients,76(34.23%)had DRP and a total of 104 DRP were found.The main problem type of DRP was treatment safety(39.42%).The involving objects of DRP were all doctors.In the severity assessment,the most involved level was"DRP reached the patient,but the patient was not harmed"(81.73%).The main reason for DRP was"choice of drugs"(67.31%),followed by"usage and dosage"(26.92%).A total of 62(59.62%)DRP intervention schemes were accepted,and the overall acceptance rate of intervention schemes was 87.32%.In the end,61(58.65%)DRPs were resolved.The drug class with the largest number of DRP cases was antiplatelet drugs.Binomial Logistic regression analysis showed that the number of drug varieties[OR=1.097,95%CI(1.030,1.167)]was the influencing factor for the occurrence of DRP in neurology inpatients(P<0.05).Conclusion DRP is common in inpatients of neurology department.Chinese Drug-Related Problems Classification System is helpful for clinical pharmacists to review and sort pharmaceutical care data,summarize common problems and solving experience,and improve the effect of pharmaceutical care.

Tibetan is a kind of medicine which extensively absorbed and fused the Chinese Traditional Medicine, Indian medicine and food through long-term practice and form the unique medical system. At the same time, the Qinghai Tibet plateau has characteristics of high altitude and lack of resources and oxygen, which has formed its unique geographical environment and grow a lot of rare medicinal plants. Tibetan medicine has a long history and is one of the relatively complete and influential ethnic medicines in China, which has played an important role in the treatment of plateau diseases. In recent years, with the increasing of economic activities in the plateau, the plateau anoxia had greatly affected the working capacity of the plateau. According to "Chinese medicine" through the literature, the pharmacological activities, active ingredients, growing environment of Tibetan medicine with good plateau hypoxia effect were reviewed and according to the site, which could be divided into the lung protection medicine, the cardiac protection medicine, the brain protection medicine, the liver protection medicine, the improvement of fatigue medicine and other medicine, which could provide theoretical basis for finding more potential anti-hypoxia drugs.

Objective:To establish a mice model of inflammatory bowel disease (IBD) induced by dextran sulfate sodium (DSS), and to analyze the changes in intestinal inflammation and macrophage subsets at different stages, so as to find a new target for the treatment of IBD.Methods:Thirty male C57BL/6 mice of 6-8 weeks were randomly divided into control group, activation stage group and resolution stage group.The latter 2 groups were given 25 g/L DSS for 5 consecutive days to establish the IBD model.After 5 days, the mice were given filtered and sterilized water and sacrificed on the 10 th and 15 th day, respectively.Colon inflammation in mice was evaluated, including body weight, disease activity index (DAI) score, changes in colon length, histopathology and histopathological score.Then the expression levels of interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, transforming growth factor (TGF)-β in colon tissues were detected by quantitative real-time PCR(qPCR). Finally, the changes of intestinal macrophage subsets were detected by flow cytometry. Results:The colon inflammation of mice in the activation stage group was significantly more severe than that in the control group, while the colon inflammation of mice in the resolution stage group was reduced.The colon length of mice in the activation stage group was (5.94±0.40) cm, which was significantly shorter than that in the control group [(7.25±0.29) cm], and the situation was slightly improved in the resolution stage with the colon length of [(6.87±0.95) cm], and the differences were statistically significant (all P<0.05). The mRNA expression levels of pro-inflammatory cytokines IL-1β, IL-6 and TNF-α in the activation stage were 53.40±6.58, 117.69±30.78 and 2.52±0.25, respectively, which were significantly higher than those in the control group (1.00±0.13, 1.00±0.39, 1.00±0.10); the mRNA expression levels of IL-1β, IL-6 and TNF-α in the resolution stage were 2.51±0.13, 5.43±0.51 and 1.73±0.14, respectively, which were significantly lower than those in the activation stages(all P<0.05). The expression level of anti-inflammatory cytokine TGF-β in the resolution stage was 2.41±0.17, which was significantly higher than that in the activation stage (0.94±0.12), and the diffe-rence was statistically significant ( P<0.05). During the progression of IBD, there were 3 groups of macrophages in the lamina propria of intestinal mucosa of mice, of which the number of F4/80 lowCD 64-MHCⅡ - macrophage subset with the lowest maturity increased significantly in the activation stage of IBD, accounting for (10.68±4.62)%, and it decreased and returned to the normal level in the resolution stage, accounting for (4.63±1.06)%, and the difference was statistically significant ( P<0.05). Conclusions:Macrophages play an important role in the progression of IBD, the hindrance of maturation and development may be the main cause of inflammatory injury in the activation stage of IBD, and the transformation of macrophage subsets may become a new target for the treatment of IBD.

Objective To investigate the relationship between the onset of lower extremity venous thrombotic disease and seasons.Methods A retrospective study was conducted, 300 patients with lower extremity venous thrombotic disease admitted to HandanCity Hospital of Traditional Chinese Medicine (TCM) from August 2012 to February 2014 were enrolled, the incidences and TCM syndromes of patients with lower extremity venous thrombotic disease in different seasons were observed, and the pathogenesis and relationships between the types of TCM syndrome and seasons were analyzed.Results There were 142 patients with lower extremity superficial thrombophlebitis, and 158 cases with lower extremity deep venous thrombosis, the incidence of lower extremity venous thrombotic disease in spring was significantly higher than that in summer and autumn [32.8% (86/262) vs. 21.3% (54/254), 18.4% (50/272), bothP < 0.01], but lower than that in winter [32.8% (86/262) vs. 37.2% (110/296)], the difference was not statistically significant (P > 0.01); while the incidence of lower extremity venous thrombotic disease in winter was significant higher than those in summer and autumn (allP < 0.01). The incidences of damp and heat downward flow type in autumn and summer were increased compared with those in winter and spring [55.6% (30/54), 60.0% (30/50) vs. 20.0% (22/110), 23.3% (20/86), allP < 0.01], while the incidences of lower extremity venous thrombotic disease with damp heat and stasis syndrome in winter and spring were increased compared with those in summer and autumn seasons [80.0% (88/110), 76.7% (66/86) vs. 44.4% (24/54), 40.0% (20/50)].Conclusions The incidence of lower extremity venous thrombotic disease is related to seasons, and the onset is high in winter and spring, damp heat and stasis syndrome being the main type; according to different seasons, clinical treatment can direct to different pathogenic factors to adopt different preventive measures interfering with the patient's constitution in order to eliminate or reduce the risk factors, achieving the effect of the disease prevention.

Objective To explore the application effects of the structured intervention model on the protective restriction in psychiatric inpatients.Methods The study investigated 91 8 psychiatric inpatients hospitalized from January 201 3 to December 201 4.The participants were randomly divided into the intervention group (n =469 )and the control group (n =449 ).The patients of intervention group received protective restriction based on the structured intervention model.A standard risk assessment was applied before and after the restriction.The patients of control group received the routine protective restriction.The protection rate, protection duration,and day-night protection time were compared between the two groups.Results The protection rate was 1 5.4% (71 /469)for the intervention group,which was lower than the rate of 20.49%(92 /449)for the control group (P <0.05 ).The difference of day-night protection was also statistically significant between the two arms (P <0.05).Conclusions The application of structured intervention model on the clinical practice can effectively reduce the protection rate and protection duration in psychiatric inpatients.

OBJECTIVEThe objective of this study is to review the research on the prognostic markers of idiopathic pulmonary arterial hypertension (IPAH).

DATE SOURCESWe searched literature from PubMed and CNKI databases both in English and Chinese up to 2013.

STUDY SELECTIONData about mortality and cut-off value are from clinical trials and identified by analysis.

RESULTSIPAH is an unexplained, progressive, and rare disease characterized by increased pulmonary artery pressure and pulmonary vascular resistance. The diagnosis is difficult, mortality of IPAH is high, and the survival periods are only 2-3 years after diagnosis. Investigations in recent years have identified a range of prognostic markers for IPAH, including the 6-minute walking test, red blood cell distribution width, and platelet levels, as well as imaging findings. Changes in these markers are important sources of information to predict the prognosis of patients with IPAH, which carries significant benefits for treatment planning.

CONCLUSIONEven though the prognosis of IPAH has been investigated, the mortality is also high. More accurate and meaningful assessment for the prognosis of IPAH is required.
