Traditional Chinese medicine （TCM） offers a rich theoretical foundation and clinical experience for the prevention and treatment of cardiovascular-kidney-metabolic syndrome（CKM）， demonstrating unique advantage. Building on previous work in managing diabetes， its complications， and chronic kidney disease， our team has proposed a five-phase evolution theory of "constraint， heat， deficiency， stasis， and toxin" as the core pathogenesis. These phases correspond to the pathological progression of constraint of phlegm-dampness， constraint transforming into heat， heat damaging qi and yin， stasis accumulated in the collateral vessels， and toxin induced by deficiency and stasis. In the prevention and treatment of CKM by TCM， it is emphasized to integrate the concept of "treating disease before it arises" with constitution theory， and incorporate the "2-5-8" prevention and treatment strategy， which combines prevention with treatment， tailors interventions to different phases， and employs comprehensive treatment modalities. Our goal is to leverage TCM's holistic advantages in preventing and treating CKM.

Objective To explore the clinical efficacy of Liuwei Dihuang Capsules for type 2 diabetes mellitus(T2DM)with yin deficiency syndrome and the effects on intestinal flora and inflammatory factors.Methods Totally 60 patients of T2DM with yin deficiency syndrome in Dongzhimen Hospital of Beijing University of Chinese Medicine from September 2022 to June 2023 were selected as the study objects,and were divided into control group and observation group according to the method of block randomization,with 30 cases in each group.Both groups received basic treatment.The control group was given a simulated agent of Liuwei Dihuang Capsules,while the observation group was given Liuwei Dihuang Capsules.The treatment course for both groups was 4 weeks.Clinical efficacy,blood glucose levels[fasting plasma glucose(FPG),2-hour postprandial plasma glucose(2 hPG),glycated albumin(GA)],serum insulin levels[fasting insulin(FINS)and insulin resistance index(HOMA-IR)],changes in gut microbiota,and serum inflammatory cytokine levels[interleukin(IL)-6,tumor necrosis factor(TNF)-α]of both groups were compared.Results The total effective rate of the observation group(76.67%)was better than that of the control group(50.00%)(P<0.05).Compared with before treatment,the FPG,2 hPG,GA,FINS and HOMA-IR decreased in the observation group,while the FPG,2 hPG and FINS decreased in the control group(P<0.05);after treatment,the Shannon index of the observation group increased after treatment(P<0.05),and the diversity of the microbiota increased;the abundance of the microbial communities such as Coprococcus 3,Cutibacterium,Pseudomonas,Faecalibaculum,Dubosiella and Mucispirillum significantly increased(P<0.05);the abundance of Sphingomonas,Corynebacterium 1,Ileibacterium,Ruminiclostridium and other microbiota communities significantly decreased(P<0.05).Compared with before treatment,the levels of IL-6 and TNF-α in both groups were significantly reduced after treatment(P<0.01,P<0.05).After treatment,the levels of IL-6 and TNF-α in the observation group were significantly lower than those in the control group(P<0.05).Conclusion Liuwei Dihuang Capsules can effectively reduce blood glucose levels in patients of T2DM with yin deficiency syndrome,improve insulin resistance,increase gut microbiota diversity,increase beneficial bacterial abundance,reduce harmful bacterial abundance,and alleviate inflammatory cytokine levels.

Objective To explore the correlation between serum inflammatory indicators and short-term prognosis in patients with single-segment lumbar intervertebral disc protrusion(LDH)treated by transforaminal endoscopic discectomy(TELD).Methods From January 2015 to June 2022,137 patients with single-segment LDH received TELD treatment.The levels of serum inflammatory factors such as C-reactive protein(CRP),white blood cell count(WBC),erythrocyte sedimentation rate(ESR),and procalcitonin(PCT)of the patients before the operation and 3 days after the operation,as well as surgical data such as anesthesia methods,operation time,and blood loss were collected.The time for patients to resume work was collected,and the pain relief and functional recovery of the patients were evaluated by using the Visual Analogue Scale(VAS)and the Oswestry Disability Index(ODI).Pearson or Spearman rank correlation analysis was used to explore the correlations between demographic characteristics,inflammatory indicators,surgical data and short-term prognosis.Results The average time for patients to return to work was(3.55±2.13)months.There were statistically significant differences in the pain and functional scores at each time point compared with those at the previous time point(P＜0.05).The CRP,WBC and PCT of the patients after the operation were significantly increased compared with those before the operation,and the difference was statistically significant(P＜0.05).The levels of CRP and PCT in patients 3 days after surgery were significantly positively correlated with VAS 6 months after surgery.The duration of symptoms and the CRP level 3 days after surgery were significantly positively correlated with ODI 6 months after surgery.BMI was significantly positively correlated with the time to return to work(P＜0.05).Conclusion There is a certain correlation between the levels of serum inflammatory indicators in patients with single-segment LDH treated with TELD and the short-term prognosis.The increase of CRP and PCT 3 days after the operation may affect the rehabilitation process of the patients.

It is believed that traditional Chinese medicine （TCM） Daoyin （conduction exercise） therapy has potential in treating diabetic foot， which is a concrete embodiment of HUANG Yuanyu's theory of one qi circulation applied in practice. Based on Daoyin therapy of Baduanjin and the Origin and Indicators of Disease （《诸病源候论》）， a Daoyin prescription for diabetic foot was compiled and created. Based on the zang-fu concept of "One Qi Circulation"， combined with the theory of chief， deputy， assistant and envoy， this article explained the theoretical basis and functional mechanism of the Daoyin prescription for diabetic foot. This Daoyin therapy is mainly based on the prone position movements， which includes seven movements， namely， pull-up， knee bending， toe tilting， phoenix nodding， internal rotation of taiji， two hands climbing feet and closing. With "phoenix nodding" and "tilting toes" as the chief， with the help of toes opening-closing and pointing-pressing momentum in prone position， regulating the central qi； with "bending the knee" and "internal rotation of taiji" as the deputy， knee and ankle flexion and extension can unblock the meridians of liver and lungs； with "pull-up" and "two hands climbing feet" as the assistant， on the one hand， assisting to unblock zang-fu organs， on the other hand， applying the yang of the foot taiyang bladder channel and du mai to warm the cold and dampness； with "closing" as the envoy to regulate all organs， so that the blood return to the natural flow of circulation. Diabetic foot Daoyin therapy could regulate internal organs and qi circulation of body， and provides a new idea for the treatment of diabetic foot.

Objective To investigate the association between recurrent low back pain(RLBP)and postoperative weight gain(PWG)after recurrent low back pain(TLIF)at three-month follow-up.Methods We analyzed 254 patients at three-month after TLIF from September 2020 to September 2022.Data such as age,gender,height and weight before surgery,smoking status,Pfirrmann grade of preoperative intervertebral disc degeneration,visual analogue scale(VAS)before surgery and 7 days,1 month and 2 months after surgery were collected.RLBP was defined for patients with low back pain with VAS score ≤3 on the 7th,1st and 2nd month after surgery,but ≥4 on the 3rd month after surgery.Three months after surgery,PWG was divided into 4 groups:＜0 kg group,0～＜5 kg group,5～＜10 kg group,and ≥10 kg group.Multivariate Logistic regression analysis of odds ratio(ORs).Results The prevalence of persistent RLBP was 18.5％(n=47).Compared to patients with a PWG of＜0 kg,patients with a PWG of 5 kg to＜10 kg and ≥ 10 kg had a higher prevalence of RLBP(OR=2.48 and 4.19,respectively);the difference was statistically significant(P＜0.05).However,no significant difference was found for patients with a PWG of 0 kg to＜5 kg.In addition,Logistic regression analysis also showed female,higher preoperative body mass index(BMI)and higher preoperative Pfirrmann grade were other three independent risk factors of RLBP.Conclusion PWG in TLIF patients is one of the independent risk factors for RLBP.Postoperative weight intervention for patients can reduce the incidence of RLBP and improve patient satisfaction with the surgery.

Objective:To investigate the interactive effect of mismatch repair (MMR) protein status and adverse clinicopathological features on prognosis of stage Ⅰ-Ⅲ colon cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 1 650 patients with colon cancer of stage Ⅰ-Ⅲ who were admitted to 7 hospitals in China from January 2016 to December 2017 were collected. There were 963 males and 687 females, aged 62(53,71)years. Patients were classified as 230 cases of MMR deficiency (dMMR) and 1 420 cases of MMR proficiency (pMMR) based on their MMR protein status. Observation indicators: (1) comparison of clinicopathological characteristics between patients of different MMR protein status; (2) analysis of factors affecting the survival outcomes of patients of dMMR; (3) analysis of factors affecting the survival outcomes of patients of pMMR; (4) interaction analysis of MMR and adverse clinicopathological features on survival outcomes. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the Mann-Whitney U test. The random forest interpolation method was used for missing values in data interpolation. Univariate analysis was conducted using the COX proportional risk regression model, and multivariate analysis was conducted using the COX stepwise regression with forward method. The coefficient of multiplication interaction effect was obtained using the interaction term coefficient of COX proportional risk regression model. Evaluation of additive interaction effects was conducted using the relative excess risk due to interaction ( RERI). Results:(1) Comparison of clinicopathological characteristics between patients of different MMR protein status. There were significant differences in age, T staging, the number of lymph node harvest, the number of lymph node harvest <12, high grade tumor between patients of dMMR and pMMR ( P<0.05). (2) Analysis of factors affecting the survival outcomes of patients of dMMR. Results of multivariate analysis showed that T staging, N staging, the number of lymph node harvest <12 were independent factors affecting the disease-free survival (DFS) of colon cancer patients of dMMR ( hazard ratio=3.548, 2.589, 6.702, 95% confidence interval as 1.460-8.620, 1.064-6.301, 1.886-23.813, P<0.05). Age and N staging were independent factors affecting the overall survival (OS) of colon cancer patients of dMMR ( hazard ratio=1.073, 10.684, 95% confidence interval as 1.021-1.126, 2.311-49.404, P<0.05). (3) Analysis of factors affecting the survival outcomes of patients of pMMR. Results of multivariate analysis showed that age, T staging, N staging, vascular tumor thrombus were independent factors affecting the DFS of colon cancer patients of pMMR ( hazard ratio=1.018, 2.214, 2.598, 1.549, 95% confidence interval as 1.006-1.030, 1.618-3.030, 1.921-3.513, 1.118-2.147, P<0.05). Age, T staging, N staging, high grade tumor were independent factors affecting the OS of colon cancer patients of pMMR ( hazard ratio=1.036, 2.080, 2.591, 1.615, 95% confidence interval as 1.020-1.052, 1.407-3.075, 1.791-3.748, 1.114-2.341, P<0.05). (4) Interaction analysis of MMR and adverse clinicopathological features on survival outcomes. Results of interaction analysis showed that the multiplication interaction effect between the number of lymph node harvest <12 and MMR protein status was significant on DFS of colon cancer patients ( hazard ratio=3.923, 95% confidence interval as 1.057-14.555, P<0.05). The additive interaction effects between age and MMR protein status, between high grade tumor and MMR protein status were significant on OS of colon cancer patients ( RERI=-0.033, -1.304, 95% confidence interval as -0.049 to -0.018, -2.462 to -0.146). Conclusions:There is an interaction between the MMR protein status and the adverse clinicopathological features (the number of lymph node harvest <12, high grade tumor) on prognosis of colon cancer patients of stage Ⅰ-Ⅲ. In patients of dMMR, the number of lymph node harvest <12 has a stronger predictive effect on poor prognosis. In patients of pMMR, the high grade tumor has a stronger predictive effect on poor prognosis.

Objective:To analyze the reinfection rates in people previously infected with SARS-CoV-2 in Zhengzhou and Yuzhou cities (first infected with Delta/B.1.617.2 variant), and Anyang city (first infected with Omicron/BA.1.1 variant) in January 2022 and the population characteristics, and compare the differences in antibody levels among different populations.Methods:Serum samples were collected from 371 previously infected, 134 reinfected and 19 uninfected people for IgG antibody detection. Among them, serum samples from 45 previously infected, 44 reinfected and 19 uninfected people were tested with different novel coronavirus variants (early original strain, BA.5.2 variant, XBB.1.5 variant) for neutralizing antibody detection.Results:The rate of reinfection was 32.82% (85/259) in Zhengzhou and Yuzhou cities, and 19.92% (49/246) in Anyang city. The IgG antibody level in reinfected people was higher than that in previously infected and uninfected people ( P<0.05). The IgG antibody level in uninfected group was higher in people vaccinated within three months than in those vaccinated six months ago ( P<0.05). The IgG antibody level in the group receiving four doses of vaccine was higher than that in the group receiving three doses of vaccine ( P<0.05). The results of true virus neutralization antibody detection showed that in the Zhengzhou and Yuzhou cases, the level of neutralization antibody against the early original strain was higher than those against the BA.5.2 variant and the XBB.1.5 variant ( P<0.05), and the level of neutralizing antibody against BA.5.2 variant was higher than that against XBB.1.5 variant ( P<0.05). In Anyang city cases, the level of neutralizing antibody against the early original strain was higher than those against BA.5.2 variant and XBB.1.5 variant ( P<0.05); in the reinfected population, the level of neutralizing antibody against the early original strain was higher than that against the XBB.1.5 variant ( P<0.05). In addition, the levels of all neutralizing antibodies in both previously infected and reinfected people were higher than those in uninfected people ( P<0.05). The level of neutralizing antibody in the infected population in Zhengzhou and Yuzhou cities was higher than that in the infected population in Anyang city and in uninfected population ( P<0.05). The levels of antibodies against BA.5.2 and anti-XBB.1.5 variants in infected people in Zhengzhou and Yuzhou cities were higher than those in uninfected people ( P<0.05). The level of neutralizing antibody against BA.5.2 variants in the previously infected population in Anyang city was higher than that in the uninfected population ( P<0.05), and the level of neutralizing antibody against XBB.1.5 variants in the infected population in Anyang city was higher than that in the uninfected population ( P<0.05). Conclusions:After infection with SARS-CoV-2, the neutralizing antibodies produced in the human body have a certain cross-protection effect on other variants, but the antibody level will gradually decrease over time. Protection from a previous early SARS-CoV-2 variants infection against the current main circulating Omicron variants (such as XBB variants) is low, and the immunity conferred by pervious infection or booster vaccination may not be able to provide sufficient protection against new variants.

Objective To observe the impacts of acupuncture and moxibustion on kelch like epichlorohydrin related protein 1(Keap1)and nuclear factor E2 related factor 2(Nrf2)signal pathway in kidney tissue of cisplatin(DDP)-induced kidney injury model mice,and to explain the protective mechanism of acupuncture and moxibustion on improving kidney injury caused by DDP.Methods Forty SPF male KM rats were randomly divided into 4 groups,with 10 rats in each group.One day before the start of treatment,the three groups of mice outside the blank group were intraperitoneally injected with cisplatin 10 mg·kg-1 according to their body weight,and the blank group was injected with the same dose of 0.9%NaCl solution.The model was established 24 hours later.Both acupuncture group and moxibustion group selected"Dazhui"(GV14),"Ganshu"(BL18),"Shenshu"(BL23)and"Zusanli(Housanli)"(ST36)for acupuncture and moxibustion respectively,once a day for 5 days.The other two groups were fixed every day without treatment.After fasting for 1 day,the contents of BUN,Scr,CysC and NGAL in serum and Keap1 and Nrf2 in renal tissue were detected by ELISA;Western blot and Real-time PCR were used to detect the protein expression and gene transcription of Keap1 and Nrf2 in the kidney tissue of mice in each group.Results Compared with the blank group,the content of Keap1 protein,protein expression and relative expression of mRNA in the model group increased(P<0.05),the content of Nrf2 protein,protein expression decreased(P<0.05),Nrf2 relative expression of mRNA increased(P<0.05);Compared with the model group,the content of Keap1 protein,the expression of Keap1 protein and the relative expression of Keap1 mRNA in the kidney of mice in the acupuncture and moxibustion groups decreased(P<0.05);Nrf2 protein content,protein expression and relative mRNA expression increased(P<0.05).Conclusion Acupuncture and moxibustion can improve the renal function of DDP renal injury model mice and enhance their antioxidant stress ability,so as to improve the renal injury caused by DDP chemotherapy.Its mechanism may be related to Keap1/Nrf2 signal pathway.
