It is proposed that the pathogenesis of rheumatoid arthritis （RA） is centered on deficiency， dampness， and blood stasis， which interact with and evolve into one another during the onset and progression of the disease. The development of RA is closely associated with insufficiency of healthy qi and the interbinding of dampness and blood stasis. Accordingly， treatment emphasizes an integrated approach that combines tonifying deficiency， eliminating dampness， and resolving blood stasis， and is implemented in three main stages. In the initial stage， therapy focuses on supporting healthy qi， dispelling dampness， and relieving impediment， with modified Huangqi Guizhi Wuwu Decoction （黄芪桂枝五物汤） combined with Yiyiren Decoction （薏苡仁汤）. In the active stage， treatment aims to eliminate dampness， resolve blood stasis， and unblock the collaterals， using modified Wutou Decoction （乌头汤） or Guizhi Shaoyao Zhimu Decoction （桂枝芍药知母汤）. In the remission stage， therapy emphasizes strengthening the spleen and reple-nishing qi to prevent recurrence， with modified Shenling Baizhu Powder （参苓白术散） combined with Guipi Decoction （归脾汤）.

Objective To investigate the clinical efficacy of Xinxuetong Oral Liquid in the treatment of patients with acute coronary syndrome(ACS).Methods A total of 80 patients with ACS of blood stasis syndrome who were hospitalized in Shunde Hospital of Guangzhou University of Chinese Medicine from January 2023 to September 2023 were randomly divided into the treatment group and control group according to random number table method,40 patients in each group.The patients in the two groups were given conventional western medicine treatment including lifestyle guidance,percutaneous coronary intervention(PCI),and conventional western medicine therapy.Additionally,the treatment group was treated with Xinxuetong Oral Liquid.The course of treatment for the two groups covered eight weeks.Before and after treatment the two groups were observed in the changes of traditional Chinese medicine(TCM)syndrome score,blood stasis syndrome score,angina pectoris score,blood lipid indicators,carotid ultrasonography indicators,echocardiography indicators,and serum levels of trimethylamine-N-oxide(TMAO),nitric oxide(NO),endothelin 1(ET-1),interleukin 8(IL-8),serine/threonine-protein kinase 1(AKT-1),and vascular endothelial growth factor A(VEGF-A).After treatment,the efficacy on TCM syndrome efficacy and the safety of the regimen in the two groups were evaluated.Results(1)During the trial,there were two cases of loss to follow-up and one case of withdrawal due to pneumonia,and eventually a total of 77 patients completed the full course of treatment,among which 39 patients were in the treatment group and 38 patients were in the control group.(2)After eight weeks of treatment,the total effective rate of the treatment group was 89.74％(35/39),and that of the control group was 63.16％(24/38).The intergroup comparison(tested by chi-square test)showed that the effective rate of TCM syndrome efficacy in the treatment group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the scores of TCM symptoms such as chest pain,chest distress,symptom aggravation at night,and palpitation in the two groups,as well as the score of gloomy complexion in the treatment group,were significantly decreased compared with those before treatment(P＜0.05 or P＜0.01),and the decrease of scores of chest distress,symptom aggravation at night,and palpitation in the treatment group was significantly superior to that in the control group(P＜0.05 or P＜0.01).(4)After treatment,the blood stasis syndrome score and angina pectoris symptom score of the two groups of patients were significantly decreased compared with those before treatment(P＜0.01),and the decrease in the treatment group was significantly superior to that in the control group(P＜0.01).(5)After treatment,the serum TMAO,ET-1,IL-8,AKT-1,and VEGF-A levels in the two groups were significantly decreased compared with those before treatment(P＜0.01),and the serum NO level was significantly increased compared with that before treatment(P＜0.01).The decrease of serum TMAO,ET-1,IL-8,and AKT-1,VEGF-A levels and the increase of serum NO level in the treatment group were significantly superior to those of the control group(P＜0.05 or P＜0.01).(6)After treatment,the total cholesterol(TCHO)and low-density lipoprotein cholesterol(LDL-C)levels of the two groups(P＜0.01)and the triglyceride(TG)level of the treatment group(P＜0.05)were decreased significantly compared with those before treatment,while the high-density lipoprotein cholesterol(HDL-C)level of the treatment group was increased significantly compared with that before treatment(P＜0.01).No obvious changes of TG and HDL-C levels before and after treatment were shown in the control group(P＞0.05).The comparison of blood lipid indicators after treatment between groups showed that there were no statistically significant differences(P＞0.05).(7)After treatment,the carotid ultrasonography indicators of carotid intima-media thickness(IMT)and Crouse score of the carotid plaque in the two groups were significantly improved compared with those before treatment(P＜0.01).However,there was no statistical significance in the comparison of the two indicators between the two groups after treatment(P＞0.05).(8)The observation of echocardiography indicators showed that only the post-treatment left ventricular diameter(LVd)of the treatment group was significantly larger than that before treatment(P＜0.05),while no obvious changes of the other echocardiography indicators before and after treatment were shown in the two groups(P＞0.05).The comparison between the groups after treatment also showed no statistically significant differences(P＞0.05).(9)During the treatment,no serious drug-induced adverse reactions or drug-related severe cardiovascular events and complications occurred in the two groups.Conclusion The combination of Xinxuetong Oral Liquid with conventional western medicine treatment exerts certain efficacy and safety on improving the clinical symptoms of patients with ACS of blood stasis syndrome,and its therapeutic mechanism may be related to the improvement of blood lipid levels,inflammatory response,and TMAO level.

Objective: To understand the nutritional literacy level and associated factors of primary and secondary school students in Beijing, so as to provide a scientific basis for improving student nutrition. Methods: From October 2022 to May 2023, a multi stage cluster random sampling method was employed to select a total of 14 568 primary, junior and senior high school students from 16 districts (ecluding the Economic Technological Development area) in Beijing. Through a survey questionnaire on nutritional literacy and dietary hehavior of school age children, basic information as well as data on nutritional literacy levels across four dimensions:nutrition related knowledge concepts, food selection, food preparation, and food intake dimensions were obtained. The Wilcoxon rank sum test, Kruskal-Wallis test, Spearman correlation analysis, Chi square test and binary Logistic regression were used for the analysis. Results: The median total score of nutritional literacy among primary and secondary school students in Beijing was 68.8. Approximately 26.0% of primary and secondary school students achieved nutritional literacy standards. The median scores and rates of meeting the standards for nutrition related knowledge concepts, food selection, food preparation and food intake dimensions were 23.0, 42.1%; 17.0, 27.4%; 6.5, 33.5%; 23.0, 33.3%, respectively. There were positive correlations between all pairs of the four dimensions ( r=0.33-0.49, P <0.05). The results of multiple Logistic regression analysis showed that primary school students, junior high school students, female students, suburban students, caregivers with a college education level and a bachelor s degree or above were the positive arrelation factors that promoted the achievement of nutritional literacy standards ( OR =2.21, 1.39, 1.18, 1.27, 1.42, 1.66, P <0.05). Conclusion The literacy level of primary and secondary school students in Beijing needs to be significantly improved. School stage, gender, region and caregiver s education level are associated factors.

Objective　To understand the impact of early and timely treatment and initial antiviral treatment regimen on mortality and attrition of antiretroviral therapy. Methods A retrospective cohort study was conducted using download data on antiretroviral therapy for HIV-infected patients in Liuzhou City, Guangxi Province, from the database of the Basic Information System for AIDS Control and Prevention (BISAC) from 2010 to 2020. The Cox proportional risk regression model was used to analyze the influencing factors of mortality and attrition. Results A total of 15 713 infected patients were included, including 53.4% aged 18-<50 years, 69.4% male, 61.0% farmer, 75.1% CD4 count <350 cells /μL before initial antiviral treatment, the overall mortality rate was 4.30/100 person-years, and the overall attrition was 2.42/100 person-years. The results of Cox regression analysis showed that the influencing factors of mortality were pretreatment CD4 counts of 350-<500 cells/μL(AHR=0.72, 95%CI: 0.63-0.81) and ≥500 cells/μL (AHR= 0.64, 95%CI: 0.55-0.76); duration from diagnosis to initial antiviral treatment 91-180 days (AHR=1.25, 95%CI: 1.08-1.45), 181-365 days (AHR=1.26, 95%CI: 1.08-1.47), and ≥365 days (AHR=1.26, 95%CI: 1.11-1.44); initial antiviral treatment regimens of D4T+3TC+EFV/NVP (AHR=1.47, 95%CI: 1.32-1.63) and AZT/D4T/TDF+3TC+LPV/r (AHR=1.73, 95%CI: 1.50-1.99). Factors affecting attrition were pretreatment CD4 counts of 350-499 cells/μL (AHR=1.32, 95%CI: 1.16-1.50) and ≥500 cells/μL (AHR=1.28, 95%CI: 1.10-1.50); interval from HIV positivity confirmation to initial dosing ≥365 days (AHR=1.21, 95%CI: 1.04-1.40), initial antiviral treatment regimens of TDF+3TC+NVP (AHR=1.32, 95%CI: 1.13-1.55), AZT+3TC+EFV/NVP (AHR=1.43, 95%CI: 1.26-1.62) and AZT/D4T/TDF+3TC+LPV/r (AHR=1.33, 95CI%: 1.06-1.67). Conclusions　Early and timely treatment and the initial antiviral treatment regimen of TDF+3TC+EFV have good efficacy, but attention should be paid to the high risk of attrition of HIV-infected people with high CD4 count before treatment.

Objective:To analyze the relationship between aquaporin 1 (AQP1) level and vascular calcification in patients with diabetes nephropathy.Methods:A total of 125 diabetic nephropathy patients admitted to Suzhou Hospital of Nanjing Medical University from March 2020 to March 2023 were retrospectively selected as case group. The case group was divided into group A (diabetes nephropathy stage Ⅰ and Ⅱ) with 31 cases, group B (diabetes nephropathy stage Ⅲ) with 32 cases, group C (diabetes nephropathy stage Ⅳ) with 39 cases, and group D (diabetes nephropathy stage V) with 23 cases. In these patients, 51 cases had vascular calcification, taken as the calcification group, and 74 cases had no vascular calcification, taken as the non calcification group. Sixty volunteers who underwent health examinations in the same hospital were selected as the control group. Receiver operating characteristic curve was used to analyze the predictive value of AQP1 on vascular calcification in diabetes nephropathy patients and to explore the related factors of vascular calcification in diabetes nephropathy patients.Results:Compared with the control group, AQP1 level and calcification rate in groups A, B, C and D were higher: 6.41 ± 1.04, 7.93 ± 1.23, 9.50 ± 1.52 and 11.37 ± 2.01 vs. 3.83 ± 0.56 ng/L, 6.45% (2/31), 28.13% (9/32), 51.28% (20/29) and 86.96% (20/23) vs. 0 ( P<0.05). Compared with group A, the level of AQP1 and calcification rate in groups B, C and D were higher ( P<0.05); compared with group B, the AQP1 level and calcification rate in groups C and D were higher ( P<0.05); compared with group C, the level of AQP1 and calcification rate in group D were higher ( P<0.05). Compared to the non calcification group, the levels of uric acid, homocysteine and cystatin C in calcification group were higher: (313.82 ± 38.72) μmol/L vs. (253.42 ± 30.14) μmol/L, (20.03 ± 3.01) μmol/L vs. (15.01 ± 2.71) μmol/L, (1.73 ± 0.26) mg/L vs. (1.30 ± 0.17) mg/L ( P<0.05). AQP1 was positively correlated with uric acid, homocysteine, and cystatin C ( P<0.05). The area under the curve of AQP1, uric acid, homocysteine and cystatin C in predicting vascular calcification in patients with diabetes nephropathy were 0.892, 0.803, 0.738 and 0.763, respectively. Taking whether vascular calcification occurs in patients with diabetes nephropathy as the dependent variable (no = 0, yes = 1), the variables of P<0.05 in the single factor analysis were selected for multivariate Logistic regression analysis. The results showed that uric acid, homocysteine, cystatin C and AQP1 were the main factors affecting vascular calcification in patients with diabetes nephropathy ( P<0.05). Conclusions:Serum AQP1 has a high predictive value for vascular calcification in diabetes nephropathy patients, and is expected to be used as a biomarker for early diagnosis of vascular calcification in diabetes nephropathy patients.

Objective:To compare the application effects of three different extubation techniques in patients with mechanical ventilation in intensive care unit (ICU).Methods:A prospective randomized controlled study was conducted. Mechanical ventilation patients admitted to the critical care department of the First Affiliated Hospital of Guangxi Medical University from July to November 2023 were enrolled. According to the random number table generated by Excel, the patients were divided into negative pressure group, positive pressure group 1 and positive pressure group 2, with 45 cases in each group. On the basis of routine nursing, the negative pressure group used the negative pressure extubation technique to remove the tracheal catheter. In the positive pressure group, the pressure support (PS) and positive end-expiratory pressure (PEEP) of the positive pressure group 1 were 7 cmH 2O (1 cmH 2O≈0.098 kPa) and 5 cmH 2O, and the PS and PEEP of the positive pressure group 2 were 15 cmH 2O and 10 cmH 2O. The main outcome measures were extubation related complications, including tachypnea, severe cough, sore throat, upper airway obstruction spasm, extubation failure, hypoxemia, and hypercapnia. The secondary outcome measures were the variation of heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure and blood oxygen saturation before and 1, 15 and 30 minutes after extubation. Results:Finally, 42 patients were included in each group. There were no significant differences in gender, age, catheter retention days, duration of mechanical ventilation, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), catheter model and diagnosis among the three groups, which were comparable. There were statistically significant differences in the incidence of tachypnea, severe cough, sore throat, upper airway obstruction spasm, hypoxemia and hypercapnia among the three groups, while there was no statistically significant difference in the failure rate of extubation. The incidence of tachypnea, severe cough, sore throat, upper airway obstruction spasm, hypoxemia and hypercapnia after extubation in positive pressure group 1 and positive pressure group 2 were lower than those in negative pressure group (7.14%, 9.52% vs. 33.33%; 7.14%, 4.76% vs. 28.57%; 61.90%, 52.38% vs. 88.10%; 11.90%, 19.05% vs. 45.24%; 7.14%, 7.14% vs. 30.95%; 4.76%, 2.38% vs. 28.57%; all P < 0.05). There were no significant differences in extubation related complications between group 1 and group 2. There were significant differences in the time effect of heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure and blood oxygen saturation 30 minutes after extubation among three groups ( F values were 145.792, 49.749, 22.486, 23.622 and 242.664, respectively, all P < 0.01). The intergroup effect of blood oxygen saturation was statistically significant ( F = 3.835, P = 0.024), and the blood oxygen saturation in positive pressure group 1 and positive pressure group 2 were higher than those in negative pressure group 1 minute and 30 minutes after extubation (1 minute after extubation: 0.97±0.02, 0.97±0.02 vs. 0.95±0.02; 30 minutes after extubation: 1.00±0.01, 1.00±0.01 vs. 0.99±0.02, all P < 0.05). The interaction effects of heart rate and blood oxygen saturation were statistically significant ( F values were 3.512 and 7.226, respectively, both P < 0.01). Conclusions:Compared with negative pressure extubation, positive pressure extubation can effectively reduce extubation related complications in ICU mechanically ventilated patients. It is beneficial to maintain stable blood oxygen saturation within 30 minutes after extubation, and has better clinical application effects. It is recommended to use low pressure extubation.

Objective:To explore the best treatment for local ablation of colon cancer liver metastases (CRLM) by meta-analysis.Methods:The electronic databases of PubMed, Web of Science, Embase, CNKI and the Cochrane Library were searched from the establishment to August 22, 2022, and studies that report outcomes with comparison between microwave ablation (WMA) and radiofrequency ablation (RFA) in CRLM treatment were selected by inclusion and exclusion criteria. Furthermore, the perioperative and survival data were statistically summarized and analyzed by Review Manager 5.3 software.Results:A total of 5 retrospective studies were included with a total sample size of 648 cases, including 316 cases (48.8%) in the WMA group and 332 cases (51.2%) in the RFA group. The results of meta-analysis showed that locoregional recurrence rate in WMA group was significantly lower than that in RFA group. The 1-year and 2-year disease-free survival (DFS) of the WMA group was significantly better than that of the RFA group with HR of 1.77 ( P=0.04, 95% CI: 1.04-3.02) and 1.60 ( P=0.02, 95% CI: 1.09-2.35), respectively. Conclusion:The local control rate and 1-year and 2-year DFS of WMA were superior to RFA.

Objective:To explore the role of navigation-assisted valgus stress method in avoiding excessive correction of lower limb mechanical axis after high tibial osteotomy (HTO).Methods:A retrospective study was carried out on osteoarthritis (OA) patients who were treated with HTO for medial compartment pain of knee from January 2020 to March 2022 in the Department of Joint Surgery, Shanghai Changhai Hospital, the First Affiliated Hospital of Naval Medical University. According to the different ways of confirming alignment during operation, they were divided into computer navigation assisted valgus stress HTO group (referred to as navigation group) and traditional rod fluoroscopy HTO group (referred to as traditional group). There were 28 patients in the navigation group, 10 males and 18 females, with age of 54.4±9.1 years (range, 41-73 years) and body mass index of 26.1±3.3 kg/m 2 (range, 19.8-35.2 kg/m 2); There were 30 patients in the traditional group, 13 males and 17 females, aged 56.9±8.5 years (range, 40-70 years), with a body mass index of 25.7±4.0 kg/m 2 (range, 19.2-32.9 kg/m 2). Measuring the mechanical femoral tibial angle (mFTA), joint line convergence angle (JLCA), medial proximal tibial angle (MPTA), Lysholm score and Hospital for Special Surgery (HSS) score before operation and at the last follow-up of the two groups, and conduct statistical analysis. Results:Both groups were followed up. The follow-up time of navigation group and traditional group was 21.3±8.7 months and 22.5±7.6 months, respectively, with no significant difference ( t=0.53, P=0.596). There were significant differences between the two groups in the amount of mechanical axis correction (ΔmFTA) and the amount of bone correction (ΔMPTA) ( t=2.09, P=0.041; t=2.58, P=0.012), while there was no significant difference in ΔJLCA ( t=0.32, P=0.753). In the navigation group, there were 9 cases (32%) of undercorrection, 17 cases (61%) with acceptable alignment, and 2 cases (7%) with over correction, while in the traditional group, there were 5 cases (17%) with under correction, 13 cases (43%) with acceptable alignment, and 12 cases (40%) with over correction. There was significant difference in the distribution rate of alignment between the two groups ( P=0.012), and the rate of overcorrection in the navigation group was significantly lower than that in the control group (7% vs. 40%, P=0.005). The intra group correlation coefficient between the navigation correction mechanical axis and ΔmFTA was 0.787. There was no significant difference in Lysholm score and HSS score between the two groups before and after surgery (all P>0.05), and they were significantly improved after operation (all P<0.05). Conclusion:Navigation-assisted valgus stress method HTO is reliable, which can accurately achieve the target alignment, reduce the incidence of over correction, and obtain good clinical results.

Objective:To explore the differences of fecal calprotectin (FC), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) between colon and small intestinal Crohn′s disease, and their predictive values for disease activity and mucosal healing in patients with small intestinal Crohn′s disease.Methods:From January 2017 to January 2023, 64 patients with Crohn′s disease who underwent capsule endoscopy in the First Affiliated Hospital of Zhejiang Chinese Medical University were enrolled, among them 28 patients had only small intestinal lesions (small intestine group) and 36 patients had lesions involving both small intestine and colon or only colon involvement (ileocolon group). The FC, CRP, and ESR levels of the two groups were detected and compared 15 days before capsule endoscopy examination. Wilcoxon rank-sum test was used for statistical analysis. Receiver operating characteristic curve analysis was used to evaluate the predictive value of FC, CRP, and ESR for disease activity and mucosal healing in patients with small intestinal Crohn′s disease.Results:The FC, CRP, and ESR levels of the small intestine group during the active phase of the disease were 1 689.00 μg/g (727.75 μg/g, 1 800.00 μg/g), 5.67 mg/L (1.00 mg/L, 17.01 mg/L), and 4.50 mm/1 h (2.00 mm/1 h, 11.00 mm/1 h), respectively; while FC, CRP, and ESR levels during the mucosal healing phase were 112.00 μg/g (46.50 μg/g, 130.50 μg/g), 1.00 mg/L (1.00 mg/L, 1.62 mg/L), and 2.00 mm/1 h (2.00 mm/1 h, 5.50 mm/1 h), respectively. The FC, CRP, and ESR levels of the ileocolon group during the active phase of the disease were 1 800.00 μg/g (895.50 μg/g, 1 800.00 μg/g), 4.94 mg/L (3.10 mg/L, 14.80 mg/L), and 10.00 mm/1 h (2.00 mm/1 h, 27.75 mm/1 h), respectively, while FC, CRP, and ESR levels during the mucosal healing phase were 66.00 μg/g (32.50 μg/g, 97.50 μg/g), 1.00 mg/L (1.00 mg/L, 1.55 mg/L), and 2.00 mm/1 h (2.00 mm/1 h, 4.50 mm/1 h), respectively. There were no statistically significant differences in FC, CRP, and ESR between the small intestine group and the ileocolon group during the active phase of the disease and mucosal healing phase (all P> 0.05). In the small intestine group, the levels of FC and CRP of patients during the active phase of the disease were 1 173.00 μg/g (312.00 μg/g, 1 800.00 μg/g) and 2.10 mg/1 L (1.00 mg/L, 16.00 mg/L), which were both higher than those of patients during the mucosal healing phase (112.00 μg/g (46.50 μg/g, 130.50 μg/g) and 1.00 mg/L (1.00 mg/L, 1.62 mg/L)), and the differences were statistically significant ( Z=-4.35 and-2.67, P<0.001 and =0.008). In the small intestine group, the level of ESR of patients during the active phase of the disease was 4.00 mm/1 h (2.00 mm/1 h, 16.00 mm/1 h), and there was no significant difference compared with that of patients during the mucosal healing phase (2.00 mm/1 h (2.00 mm/1 h, 5.50 mm/1 h)) ( P>0.05). When the cut-off level of FC was 188.50 μg/g, the sensitivity, specificity, and area under the curve for predicting disease activity in patients with small intestinal Crohn′s disease was 93.3%, 100.0%, and 0.964, respectively. When the cut-off value of CRP was 3.12 mg/L, the sensitivity, specificity, and area under the curve for predicting disease activity in patients with small intestinal Crohn′s disease was 46.7%, 92.3%, and 0.744, respectively. When the cut-off level of ESR was 10.00 mm/1 h, the sensitivity, specificity, and area under the curve for predicting disease activity in patients with small intestinal Crohn′s disease was 33.3%, 100.0%, and 0.654, respectively. There were no statistically significant differences in the area under the curve between the combinations of FC and CRP, FC and ESR, FC, CRP and ESR, and FC alone for predicting disease activity in patients with small intestinal Crohn′s disease (0.964, 0.959, and 0.959 vs. 0.964, all P> 0.05). There was a statistically significant difference in the area under the curve between the combination of CRP and ESR and FC alone in predicting disease activity in patients with small intestinal Crohn′s disease (0.708 vs. 0.964, Z=-2.57, P=0.010). Conclusions:There are no statistically significant differences in FC, CRP, and ESR between colon and small intestinal Crohn′s disease. FC has a high predictive value for disease activity and mucosal healing in patients with small intestinal Crohn′s disease and has certain clinical application value.
