Cost-Effectiveness Analysis of Combined Chemotherapy Regimen Containing Bedaquiline in the Treatment of Multidrug-Resistant Tuberculosis in China / 生物医学与环境科学（英文）

OBJECTIVE@#This study aims to estimate the cost-effectiveness of the combined chemotherapy regimen containing Bedaquiline (BR) and the conventional treatment regimen (CR, not containing Bedaquiline) for the treatment of adults with multidrug-resistant tuberculosis (MDR-TB) in China.@*METHODS@#A combination of a decision tree and a Markov model was developed to estimate the cost and effects of MDR patients in BR and CR within ten years. The model parameter data were synthesized from the literature, the national TB surveillance information system, and consultation with experts. The incremental cost-effectiveness ratio (ICER) of BR vs. CR was determined.@*RESULTS@#BR ( vs. CR) had a higher sputum culture conversion rate and cure rate and prevented many premature deaths (decreased by 12.8%), thereby obtaining more quality-adjusted life years (QALYs) (increased by 2.31 years). The per capita cost in BR was as high as 138,000 yuan, roughly double that of CR. The ICER for BR was 33,700 yuan/QALY, which was lower than China's 1× per capita Gross Domestic Product (GDP) in 2020 (72,400 yuan).@*CONCLUSION@#BR is shown to be cost effective. When the unit price of Bedaquiline reaches or falls below 57.21 yuan per unit, BR is expected to be the dominant strategy in China over CR.

Bamboo-based medicinal moxibustion for chronic fatigue syndrome: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the clinical efficacy of bamboo-based medicinal moxibustion for chronic fatigue syndrome (CFS), and to preliminarily explore its action mechanism.@*METHODS@#Sixty-four patients with CFS were randomly divided into a moxibustion group (32 cases, 1 case dropped off, 1 case excluded) and an acupuncture group (32 cases, 2 cases dropped off). The patients in the moxibustion group were treated with bamboo-based medicinal moxibustion, while the patients in the acupuncture group were treated with routine acupuncture. Both groups were treated once a day, 6 days as a course of treatment with 1 day interval, for a total of 2 courses of treatment. Before treatment, 1 and 2 courses into treatment and in the follow-up of 14 days after treatment, the fatigue scale-14 (FS-14) and somatic and psychological health report (SPHERE) scores were observed in the two groups. Before and after treatment, the contents of CD+3, CD+4, CD+8 of peripheral blood T lymphocyte subsets were measured and CD+4/CD+8 ratio was calculated; the clinical efficacy of the two groups was compared.@*RESULTS@#Compared before treatment, the FS-14 and SPHERE scores in the two groups were decreased 1 and 2 courses into treatment and in the follow-up (P<0.01), and the FS-14 and SPHERE scores in the moxibustion group were lower than those in the acupuncture group (P<0.01, P<0.05). Compared before treatment, the contents of CD+3, CD+4 and CD+4/CD+8 ratio in the moxibustion group were increased after treatment (P<0.01). There was no significant difference of CD+3, CD+4, CD+8 and CD+4/CD+8 ratio between before and after treatment in the acupuncture group (P>0.05). After treatment, the contents of CD+3 and CD+4 in the moxibustion group were higher than those in the acupuncture group (P<0.05). The total effective rate was 93.3% (28/30) in the moxibustion group, which was higher than 73.3% (22/30) in the acupuncture group (P<0.05).@*CONCLUSION@#Bamboo-based medicinal moxibustion could improve the physical and mental fatigue symptoms and psychological status in patients with CFS. Its effect may be related to regulating the contents of CD+3, CD+4 of peripheral blood T lymphocyte subsets and CD+4/CD+8 ratio.

Objective: To investigate the clinical characteristics, serogroups and antimicrobial resistance of invasive non-typhoid Salmonella infection in children at Xiamen. Methods: Retrospective cohort study. The clinical manifestations, treatment, prognosis, serogroups and antimicrobial resistance of 29 hospitalized children with invasive non-typhoid Salmonella infection confirmed by blood, cerebrospinal fluid, bone marrow and other sterile body fluids or deep pus culture at the Department of Infectious Diseases, the Department of Orthopedics and the Department of General Surgery in Xiamen Children's Hospital from January 2016 to December 2021 were analyzed. According to the clinical diagnosis criteria, the patients were divided into sepsis group and non-sepsis group (bacteremia and local suppurative infection). The inflammatory markers, serogroups distribution and drug resistance were compared between the two groups. Comparison between groups using Mann-Whitney U test and χ2 test. Results: Among the 29 cases, there were 17 males and 12 females, with an onset age of 14 (9, 25) months, and 10 cases (34%) of patients were younger than 1 year old, 15 cases (52%) under 1 to 3 years old, and 4 cases (14%) greater than or equal 3 years old. The onset time of 25 cases (86%) was from April to September. The diseases included 19 cases (66%) septicemia (2 of which were combined with suppurative meningitis), 10 cases (34%) non-sepsis group, including 7 cases bacteremia and 3 cases local suppurative infection (2 cases of osteomyelitis, 1 case of appendicitis with peritonitis). The clinical manifestations were fever in 29 cases (100%), diarrhea and abdominal pain in 18 cases (62%), cough and runny nose in 10 cases (34%). Eighteen cases (62%) were cured and 11 cases (38%) were improved by effective antibiotics treatment. C-reactive protein in sepsis group was significantly higher than that in non-sepsis group (25.2 (16.1, 56.4) vs. 3.4 (0.5, 7.5) mg/L, Z=-3.81, P<0.001).The serogroups of C, B and E were the most prevalent among non-typhoid Salmonella isolates, accounting for 10 cases (34%), 9 cases (31%) and 7 cases (24%) respectively. Antibacterial drug sensitivity test showed that the sensitivity rates of imipenem, ertapenem and piperaciratazobactam were all 100% (31/31), those of ceftazidime, ceftriaxone, and cefepime were 94% (29/31), 94% (29/31) and 97% (30/31) respectively. The drug resistance rates of ampicillin, ampicillin-sulbactam and trimethoprim-sulfamethoxazole were 51% (16/31), 48% (15/31) and 48% (15/31) respectively, those of cefazolin, cefotetan, tobramycin, gentamicin and amikacinwere all 100% (31/31). There were no significant differences in the drug resistance rates of ceftazidime, ceftriaxone, aztreonam, ampicillin-sulbactam, ampicillin, trimethoprim-sulfamethoxazole and ciprofloxacin between the sepsis group and the non-sepsis group (χ2=0.31,0.31,0.00,0.02,0.02,0.02,0.26, all P>0.05). Conclusions: Invasive non-typhoid Salmonella infection in children at Xiamen mainly occurred in infants younger than 3 years old.The main clinical manifestations are fever, abdominal pain and diarrhea. C-reactive protein can be served as the laboratory indicators for indicating sepsis. The third generation of cephalosporins is recommended as the first choice for treatment.

The characteristics and correlations of vaginal flora in women with cervical lesions / 中华肿瘤杂志

Objective: To explore the characteristics and correlations of vaginal flora in women with cervical lesions. Methods: A total of 132 women, including 41 women diagnosed with normal cervical (NC), 39 patients with low-grade cervical intraepithelial neoplasia (CIN 1), 37 patients with high-grade cervical intraepithelial neoplasia (CIN 2/3) and 15 patients with cervical squamous cell carcinoma (SCC), who came from the gynecological clinic of Second Hospital of Shanxi Medical University during January 2018 to June 2018, were enrolled in this study according to the inclusive and exclusive criteria strictly. The vaginal flora was detected by 16S rDNA sequencing technology. Co-occurrence network analysis was used to investigate the Spearman correlations between different genera of bacteria. Results: The dominant bacteria in NC, CIN 1 and CIN 2/3 groups were Lactobacillus [constituent ratios 79.4% (1 869 598/2 354 098), 63.6% (1 536 466/2 415 100) and 58.3% (1 342 896/2 301 536), respectively], while Peptophilus [20.4% (246 072/1 205 154) ] was the dominant bacteria in SCC group. With the aggravation of cervical lesions, the diversity of vaginal flora gradually increased (Shannon index: F=6.39, P=0.001; Simpson index: F=3.95, P=0.012). During the cervical lesion progress, the ratio of Lactobacillus gradually decreased, the ratio of other anaerobes such as Peptophilus, Sneathia, Prevotella and etc. gradually increased, and the differential bacteria (LDA score >3.5) gradually evolved from Lactobacillus to other anaerobes. The top 10 relative abundance bacteria, spearman correlation coefficient>0.4 and P<0.05 were selected. Co-occurrence network analysis showed that Prevotella, Peptophilus, Porphyrinomonas, Anaerococcus, Sneathia, Atopobium, Gardnerella and Streptococcus were positively correlated in different stages of cervical lesions, while Lactobacillus was negatively correlated with the above anaerobes. It was found that the relationship between vaginal floras in CIN 1 group was the most complex and only Peptophilus was significantly negatively correlated with Lactobacillus in SCC group. Conclusions: The increased diversity and changed correlations between vaginal floras are closely related to cervical lesions. Peptophilus is of great significance in the diagnosis, prediction and early warning of cervical carcinogenesis.

Establishment and validation of a new predictive equation with multiple risk factors for the development of cardiorenal syndrome type 1 in patients with acute myocardial infarction / 中华心血管病杂志

Objective: To investigate the independent risk factors of cardiorenal syndrome type 1 (CRS1) in patients with acute myocardial infarction (AMI) and to build a predictive equation for the development of CRS1 in these patients. Method: Consecutive inpatients with AMI, who hospitalized from January 2017 to December 2018 in the Hunan Provincial People's Hospital, were enrolled in this case-control study. Patients were divided into CRS1 group and non-CRS1 group according to the presence or absence of CRS1.The clinical data were collected through the electronic medical record system of Hunan Provincial People's Hospital. The matching process was conducted with a minimum-distance scoring method and a 1∶1 match between the CRS1 group and the no-CRS1 group, the propensity score was calculated through the logistic regression model. Factors with statistically significant differences in univariate analysis were included in the multivariate logistic regression model to analyze the risk factors of AMI patients with CRS1, then the independent risk factors were used to establish a predicting equation for CRS1 by logistic regression function for model building. Area under the curve (AUC) value and the best cut-off value of the combined predictors was determined according to the ROC curve. Python 3.8 software was used to perform 10-fold cross-validation on modeling samples. Results: A total of 942 patients were included, there were 113 cases in CRS1 group and 829 cases in non-CRS1 group. Ultimately, 99 CRS1 patients were successfully matched to 99 non-CRS1 patient using 1∶1 matching. After propensity score matching, the baseline age and sex along with heart rate, mean arterial pressure, percentage of people with a history of diabetes, hypertension, ST-segment elevation myocardial infarction, myocardial ischemia time, angiotensin converting enzyme inhibitors or angiotensin Ⅱ receptor blockers use, and β receptor blocker use were similar between the two groups(all P>0.05). The contrast agent dosage was also similar between the two groups (P=0.266). The peak cardiac troponin I (cTnI), N-terminal pro-brain natriuretic peptide(NT-proBNP), white blood cell count, base estimated glomerular filtration rate (eGFR), albumin and hemoglobin levels were statistically significant between the two groups (all P<0.05). Multivariate logistic regression analysis showed that decreased baseline eGFR, increased NT-proBNP, peak cTnI concentrations and white blood cell count were independent risk factors of CRS1 in AMI patients (all P<0.01).The predicting equation of the combined predictor was established by transforming the logistic model equation, L=0.031×cTnI+0.000 2×NT-proBNP-0.024×eGFR+0.254×white blood cell count, where L represented the combined predictor. ROC curve analysis indicated that the AUC of the peak cTnI, NT-proBNP, baseline eGFR, white blood cell count, and combined predictor were 0.76, 0.85, 0.79, 0.81, and 0.92 respectively (all P<0.05), and the cutoff value of combined predictor was 2.6. The AUC of ROC curve after the model's ten-fold cross validation was 0.89. Conclusions: Decreased baseline eGFR, increased NT-proBNP, peak cTnI concentrations and white blood cell count are the independent risk factors for CRS1 in AMI patients. The combined predictor equation based on the above 4 biomarkers presents a good predictive value for CRS1 in AMI patients.

Abnormal Circadian Clock Ｐromotes AOM / DSS-induced Colon Carcinogenesis in Mice by Remodeling Tumor Metabolism / 中国生物化学与分子生物学报

Abnormal circadian clock has been identified as an independent risk factor for tumorigenesis, and is closely related to the occurrence and development of tumor. As metabolic disorder is also one of the important characteristics of tumorigenesis, therefore it is particularly important to investigate the regulatory relationship between biological clock and tumor metabolism. In this study, the effect of abnormal circadian clock on colon cancer growth was evaluated by azoxymethane (AOM) / dextran sodium sulfate (DSS) -induced colitis-associated carcinogenesis (CAC) mice model. The result showed that abnormal circadian clock aggravated anal swelling, redness, bloody and anorectal prolapse in CAC mice, and significantly increased the number and volume of CAC polyps (P <0. 05 or P <0. 01), and reduced the intestinal length, body weight, survival rate of CAC mice and the expression levels of inflammatory factors IL-1β (interleukin-1 beta) and TNFα (tumor necrosis factor α) (P < 0. 05 or P < 0. 01), indicating that abnormal biological clock promotes the occurrence and development of CAC. Further, non-target metabonomics analysis of serum samples from mice was performed by liquid chromatography-mass spectrometry (LC-MS) . The result showed that compared with CAC mice with normal circadian rhythm, 27 differential metabolites were identified in CAC mice with disrupted circadian clock, and 9 metabolic pathways were enriched by KEGG (kyoto encyclopedia of genes and genomes) database. These results suggest that abnormal circadian clock can significantly change the relative abundance of some metabolites in serum samples from CAC mice, remodel tumor metabolism, and result in the development of CAC in mice. This study reveals the pivotal role of tumor metabolism in the abnormal circadian clock promoting the growth of CAC in mice, providing a new experimental basis for the interaction between circadian clock and metabolic homeostasis in the occurrence and development of colon cancer.

Aim To investigate the vasodilating effect of suberoylanilide hydroxamic acid ( SAHA) on isolated thoracic aorta of rats and the possible mechanisms. Methods Isolated thoracic aorta of rats were used to perfuse, and to observe the effect of accumulated concentration of SAHA (0.3, 1, 3, 10 and 30 p,mol • L_1) on isolated thoracic aorta at basal state, KC1 and NE precontracted state. At the same time, L-NAME, Indo, PMA and SP were used to explore its possible mechanisms of relaxing isolated thoracic aorta, and to investigate the role of the Ca2 during the vasodilating process. Results SAHA could relax KC1 and NE precontracted isolated thoracic aorta of rats (P <0. 01), and the effect on endothelium-intact was stronger than that on endothelium-denuded thoracic aorta (P < 0.01), but there was no significant effect on thoracic aorta at basal state. The vasodilatory effect of SAHA could be inhibited by L-NAME, Indo and PMA (P < 0.05), while that could be promoted by SP ( P < 0. 01). SAHA could attenuate vasoconstriction induced by CaCl2 and NE through inhibiting extracellular Ca2 + influxe and intracellular Ca2 release in a concentration-dependent manner ( P < 0. 01). Conclusions The vasodilating mechanisms of SAHA may be related to the increased production of vasodilatory factors NO and PGt2, and the inhibition of PKC, and the inhibition of extracellular Ca2 + influxe and intracellular Ca2 + release.

The mechanism of Er-xian Decoction in regulating lipid metabolism disorders on bilateral ovariectomized rats based on metabolomics study / 药学学报

Studies have shown that women's menopause caused by permanent cessation of ovarian function is closely related to lipid metabolism disorders. Er-xian Decoction has been used in the clinical treatment for gynecological diseases and has a good effect on diseases related to reduced sex hormone function. In this study, metabolomics was performed on bilateral ovariectomized model rats within 12 weeks after modeling to mimic the physiological state of menopausal women in different menopausal stages and Er-xian Decoction dosed model rats. The results of liver oil red O staining sections showed lipid metabolic disorder of bilateral ovariectomized model rats and the regulating effects of Er-xian Decoction. 46 potential biomarkers (6 steroid hormones, 3 sphingolipids, 11 phospholipids and 26 glycerides) in plasma and 32 potential biomarkers (1 steroid hormones, 20 phospholipids and 11 glycerides) in liver were obtained based on lipidomics analysis. Then, we analyzed the differential metabolic pathways and construct the lipid metabolism network significantly regulated by Er-xian Decoction. The results provided valuable information for in-depth understanding of the gradual changes on lipid metabolism disorders under menopausal conditions and the characteristics and mechanisms of compound Er-xian Decoction's regulatory effects. The study complied with the procedures established by the Animal Experiment Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and passed the animal experiment ethics examine (No. 00000918).

Hypertension Prevalence, Awareness, Treatment, and Control and Their Associated Socioeconomic Factors in China: A Spatial Analysis of A National Representative Survey / 生物医学与环境科学（英文）

Objective@#We aimed to investigate and interpret the associations between socioeconomic factors and the prevalence, awareness, treatment, and control of hypertension at the provincial level in China.@*Methods@#A nationally and provincially representative sample of 179,059 adults from the China Chronic Disease and Nutrition Surveillance study in 2015-2016 was used to estimate hypertension burden. The spatial Durbin error model was fitted to investigate socioeconomic factors associated with hypertension indicators.@*Results@#Overall, it was estimated that 29.20% of the participants were hypertensive nationwide, among whom, 34.32% were aware of their condition, 27.69% had received antihypertensive treatment, and 7.81% had controlled their condition. Per capita gross domestic product (GDP) was associated with hypertension prevalence (coefficient: -2.95, 95% @*Conclusion@#Hypertension indicators were not only directly influenced by socioeconomic factors of local area but also indirectly affected by characteristics of geographical neighbors. Population-level strategies should involve optimizing supportive socioeconomic environment by integrating clinical care and public health services to decrease hypertension burden.

Treatment of pulmonary fibrosis in one convalescent patient with corona virus disease 2019 by oral traditional Chinese medicine decoction: A case report / 中西医结合学报

After one-month of oral treatment with traditional Chinese medicine decoction, without using other drugs, the lung inflammatory exudate, pulmonary fibrosis and quality of life of a 61-year-old female patient with corona virus disease 2019 (COVID-19) were significantly improved. No recurrence or deterioration of the patient's condition was found within seven weeks of treatment and follow-up, and no adverse events occurred, indicating that oral Chinese medicine decoction was able to improve the pulmonary inflammation and fibrosis in a patient recovering from COVID-19, but further research is still needed.
