Objective To investigate the clinical efficacy of Bushen Jianpi Recipe(mainly composed of Astragali Radix,Epimedii Folium,Dioscoreae Rhizoma,Salviae Miltiorrhizae Radix et Rhizoma,Cervi Cornus Colla,Astragali Complanati Semen,Polygoni Multiflori Radix Preparata,Polygonati Rhizoma,Puerariae Lobatae Radix,and Rhei Radix et Rhizoma)on patients with type 2 diabetes mellitus(T2DM)complicated with dyslipidemia and differentiated as spleen-kidney deficiency type,and to observe its effect on the level of adiponectin(ADP).Methods Ninety patients with T2DM complicated with dyslipidemia and differentiated as spleen-kidney deficiency type were randomly divided into western medicine group,Chinese medicine(CM)group,and combination of CM and western medicine group(hereinafter referred to as combination group),and each group had 30 patients.All of the 3 groups were given conventional hypoglycemic treatment.Moreover,the western medicine group was given oral use of Atorvastatin Calcium Tablets,CM group was given Bushen Jianpi Recipe,and the combination group was given Atorvastatin Calcium Tablets together with Bushen Jianpi Recipe orally.The course of treatment lasted for 8 weeks.The changes of traditional Chinese medicine(TCM)syndrome scores,glucose and lipid metabolism indexes,fasting insulin(FINS),insulin resistance index(HOMA-IR)and serum ADP levels of the three groups were observed before and after the treatment.After treatment,the efficacy of TCM syndrome of the three groups was evaluated.Results(1)After 8 weeks of treatment,the total effective rates for TCM syndrome efficacy in the western medicine group,CM group,and combination group were 66.67%(20/30),90.00%(27/30),and 93.33%(28/30),respectively.The intergroup comparison showed that the TCM syndrome efficacy of the CM group and the combination group was significantly superior to that of the western medicine group(P＜0.05).(2)After treatment,the TCM syndrome scores in all of the three groups were decreased compared with those before treatment(P＜0.01),and the decreases of the scores in both CM group and combination group was superior to that in the western medicine group(P＜0.05 or P＜0.01).(3)After treatment,the levels of lipid metabolism parameters of total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C)in the three groups were improved to various degrees compared with the pre-treatment levels,of which the levels of TC,TG,and LDL-C were significantly decreased,and the level of HDL-C was significantly increased in comparison with that before treatment,and the differences were statistically significant(P＜0.05 or P＜0.01).The intergroup comparison showed that the decrease of TC and LDL-C and the increase of HDL-C in the CM group were inferior to those in the western medicine group and the combination group(P＜0.05 or P＜0.01).(4)After treatment,the levels of glucose metabolism parameters of fasting plasma glucose(FPG),2-hour postprandial glucose(2hPG),glycated hemoglobin(HbA1c),FINS,and HOMA-IR in the CM group and the combination group were significantly decreased compared with those before treatment(P＜0.05 or P＜0.01),while only the levels of FPG,2hPG,and HOMA-IR in the western medicine group were decreased compared with those before treatment(P＜0.05 or P＜0.01).The intergroup comparison showed that the patients in the decrease of FPG,2hPG,HbA1c,FINS,and HOMA-IR levels in the CM group and the combination group was significantly superior to that in the western medicine group(P＜0.05 or P＜0.01).(5)In terms of adipokines,the serum ADP level in the three groups after treatment was significantly increased compared with that before treatment(P＜0.05 or P＜0.01),and the increase of serum ADP level in both CM group and combination group was significantly superior to that in the western medicine group(P＜0.05).Conclusion Bushen Jianpi Recipe has certain effect on regulating lipid metabolism,and has obvious advantages in improving clinical symptoms and insulin resistance,lowering blood glucose,and increasing ADP level in patients with T2DM complicated with dyslipidemia and differentiated as spleen-kidney deficiency type.

Objective To investigate the associations of reproductive health indicators with lung function and chronic obstructive pulmonary disease(COPD)among women aged 40 years and above.Methods From Jul to Sep,2021,female subjects aged 40 years and above were randomly selected from the Shanghai Suburban Adult Cohort and Biobank for COPD screening.A questionnaire was used to obtain information on demographic characteristics and reproductive health indicators.Linear regression was used to analyze the effects of reproductive health indicators on forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1).Logistic regression was also used to analyze the effects of reproductive health factors on FVC as a percentage of the predicted value(FVC%Pred)and FEV1%Pred as well as on COPD.Results A total of 1876 women aged 40 years and above were enrolled with mean age of(62.1±8.2)years old,among them,78.1%were menopausal,and 40.9%had been pregnant≥3 times.Multivariate analysis showed that FVC and FEV1 decreased in postmenopausal women,but menopause was not associated with a decrease in their percentage of predicted values.Pregnancies≥3 times was a risk factor for COPD(for 3 times,OR=4.92,95%CI:1.48-19.95,P<0.05;for≥4 times,OR=9.06,95%CI:2.32-41.57,P<0.01),while pregnancies of 2 times did not increase the risk of COPD.Conclusion In women aged 40 years and above,menopause is associated with poorer FVC and FEV1,and excessive pregnancy(≥3 times)is a risk factor for COPD.

Nutritional therapy is a core component of critically ill patient management,and the enteral route has become the preferred method due to its dual roles of nutrition and non-nutrition. The use of vasoactive medications makes enteral nutrition decisions more challenging for these patients. This review systematically examines the pathophysiological effects of vasoactive medications on gastrointestinal tract of critically ill patients,the current value and safety of enteral nutrition in this patient's population,summarizes the optimal strategies for implementing enteral nutrition in these patients for clinical reference.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Ulcerative colitis(UC) is a recurrent, intractable inflammatory bowel disease. Coptidis Rhizoma and Bovis Calculus, serving as heat-clearing and toxin-removing drugs, have long been used in the treatment of UC. Berberine(BBR) and ursodeoxycholic acid(UDCA), the main active components of Coptidis Rhizoma and Bovis Calculus, respectively, were employed to obtain UDCA-BBR supramolecular nanoparticles by stimulated co-decocting process for enhancing the therapeutic effect on UC. As revealed by the characterization of supramolecular nanoparticles by field emission scanning electron microscopy(FE-SEM) and dynamic light scattering(DLS), the supramolecular nanoparticles were tetrahedral nanoparticles with an average particle size of 180 nm. The molecular structure was described by ultraviolet spectroscopy, fluorescence spectroscopy, infrared spectroscopy, high-resolution mass spectrometry, and hydrogen-nuclear magnetic resonance(H-NMR) spectroscopy. The results showed that the formation of the supramolecular nano-particle was attributed to the mutual electrostatic attraction and hydrophobic interaction between BBR and UDCA. Additionally, supramolecular nanoparticles were also characterized by sustained release and pH sensitivity. The acute UC model was induced by dextran sulfate sodium(DSS) in mice. It was found that supramolecular nanoparticles could effectively improve body mass reduction and colon shortening in mice with UC(P<0.001) and decrease disease activity index(DAI)(P<0.01). There were statistically significant differences between the supramolecular nanoparticles group and the mechanical mixture group(P<0.001, P<0.05). Enzyme-linked immunosorbent assay(ELISA) was used to detect the serum levels of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6), and the results showed that supramolecular nanoparticles could reduce serum TNF-α and IL-6 levels(P<0.001) and exhibited an obvious difference with the mechanical mixture group(P<0.01, P<0.05). Flow cytometry indicated that supramolecular nanoparticles could reduce the recruitment of neutrophils in the lamina propria of the colon(P<0.05), which was significantly different from the mechanical mixture group(P<0.05). These findings suggested that as compared with the mechanical mixture, the supramolecular nanoparticles could effectively improve the symptoms of acute UC in mice. The study provides a new research idea for the poor absorption of small molecules and the unsatisfactory therapeutic effect of traditional Chinese medicine and lays a foundation for the research on the nano-drug delivery system of traditional Chinese medicine.

In order to establish the standardized processing technology of the hot water washing of Euodiae Fructus, this study, based on the traditional processing method of hot water washing of Euodiae Fructus recorded in ancient works and modern processing specifications of traditional Chinese medicine decoction pieces, took the yield of decoction pieces and the content of main components as the indicators and optimized the processing conditions by orthogonal test based on the results of single factor investigation. At the same time, electronic tongue technology was used to analyze the change law of the taste index of Euodiae Fructus during the hot water washing. The results of the single factor investigation showed that the content of the main components in Euodiae Fructus showed some regular changes during the processing. Specifically, the content of chlorogenic acid, hyperin, isorhamnetin-3-O-rutinoside, isorhamnetin-3-O-galactoside, and dehydroevodiamine decreased significantly, with average decreases of-23.75%,-27.80%,-14.04%,-14.03%, and-13.11%, respectively. The content of limonin increased significantly with an average increase of 19.83%. The content of evodiamine, rutaecarpine, evocarpine, and dihydroevocarpine showed fluctuating changes and generally increased, with average variation amplitudes of 0.54%,-3.78%, 2.69%, and 5.13%, respectively. The orthogonal test results showed that the optimum processing parameters for the hot water washing of Euodiae Fructus were as follows: washing time of 2 min, the solid-to-liquid ratio of 1∶10 g·mL~(-1), washing temperature of 80 ℃, washing once, and drying at 50 ℃. After the hot water washing processing, the average yield of Euodiae Fructus pieces was 94.80%. The content of limonin, evodiamine, and rutaecarpine was higher than those of raw pro-ducts, and the average transfer rates were 102.56%, 103.15%, and 105.16%, respectively. The content of dehydroevodiamine was lower than that of the raw products, and the average transfer rate was 83.04%. The results of taste analysis showed that the hot water washing could significantly reduce the salty, astringent, and bitter tastes of Euodiae Fructus. This study revealed the influence of the hot water washing on the content of main components and taste of Euodiae Fructus, and the processing technology of the hot water was-hing of Euodiae Fructus established in this study was stable, feasible, and suitable for industrial production, which laid a foundation for clarifying its processing principle and improving the quality standard and clinical application value of decoction pieces.

Objective:To investigate the effects of different doses of oxiracetam (ORC) on the neurological impairment and oxidative stress ability of lead(Pb)-exposed rats.Methods:Total 32 male SD rats with SPF grade were randomly divided into control group, the lead-exposed group, low-dose ORC intervention group and high-dose ORC intervention group according to the random number table method, with 8 rats in each group.The neurobehavioral indexes of rats were measured by gait score, tail flicking test, hindlimb support test and Morris water maze test.The lead content in hippocampal tissue was detected by spectrophotometry.The cell morphology of hippocampal tissue was observed by HE staining.Superoxide dismutase (superoxide dismutase, SOD) level in hippocampal tissues was detected by xanthine oxidase, and the level of malondialdehyde (MDA) in the hippocampus tissue was detected by the thiobarbiturate, and the level of glutathione peroxidase (GPx) in the hippocampus tissue was detected by chemical colorimetric.SPSS 24.0 software was used for statistical analysis, one-way ANOVA was used for multiple group comparisons and LSD- t test was used for further pairwise comparisons. Results:(1)After 8 weeks of lead exposure, there was no significant difference in body weight among the 4 groups( F=0.869, P=0.469). (2)Results of neurobehavioral indicators: there were statistically significant differences in gait scores, tail flick time, hind limb deployment distance, escape latency, and number of crossing platforms among the four groups of rats ( F=7.854, 13.630, 8.484, 23.485, 45.457, all P<0.05). The gait score, tail flick time, hind limb deployment distance, and escape latency of the lead-exposed group rats were higher than those of the control group (all P<0.05), while the number of crossing platforms was lower than that of the control group ( P<0.05). The gait score, tail flick time, hind limb deployment distance, and escape latency of the high-dose ORC intervention group were lower than those of the lead exposed group (all P<0.05), and the number of crossing platforms was higher than that of the lead exposed group ( P<0.05). (3)Lead content in hippocampal tissue: there was a statistically significant difference in lead content in the hippocampus of the four groups( F=309.013, P<0.001). The lead contents of lead exposed group ((1.21±0.10)μg/g), low-dose ORC intervention group ((1.03±0.10)μg/g) and high-dose ORC intervention group ((1.02±0.06)μg/g) were higher than that of the control group((0.02±0.00) μg/g) (all P<0.05), while the lead content in the low-dose ORC intervention group and high-dose ORC intervention group were both lower than that of the lead exposed group (both P<0.05). (4) HE staining showed that compared with the control group, the hippocampal tissue cells in the lead exposed group were arranged disordered, the tissue was loose, and the number of cells was reduced.Compared with the lead exposed group, the hippocampal histiocytes were closely arranged and regular, and the nuclei were fuller.(5)Oxidative stress levels in hippocampal tissue: there were significant differences in MDA, GPx content and SOD activity of hippocampal tissues in the four groups( F=69.879, 56.757, 11.644, all P<0.001). The levels of SOD ((2.03±0.18)U/mg, (3.42±0.26)U/mg), GPx((67.29±7.94)nmol/mg, (89.50±7.94)nmol/mg) in the hippocampus tissue of the lead exposed group were lower than those of the control group (all P<0.05), while the content of MDA was higher than that of the control group((43.73±3.74) nmol/mg, (16.42±1.60) nmol/mg)( P<0.05). The levels of SOD ((3.32±0.12) U/mg) and GPx ((84.11±6.26) nmol/mg) in the high-dose ORC intervention group were higher than those in the lead exposed group (both P<0.05), while the levels of MDA ((21.05±2.56) nmol/mg) was lower than that in the lead exposed group ( P<0.05). Conclusion:ORC can alleviate neurological damage in rats caused by lead exposure, which may be related to the up-regulation of antioxidant capacity of hippocampal tissues, thereby improving pathological damage.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.
