ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

Objective To construct a nomogram to predict the prognosis of patients with gallbladder cancer(GBC).Methods The clinicopathological data of GBC patients were extracted from the SEER database,and the independent prognostic factors of GBC patients were analyzed by Cox regression,and a nomogram was constructed.Finally,the column diagrams in the training queue and validation queue are verified.Results Age,T stage,M stage,histological grade,radiotherapy,surgery and tumor size were independent prognostic factors in GBC patients,and the differences were statistically significant(P＜0.05).In the training cohort,the C index was 0.735(95％CI=0.721～0.749),and the AUC values at 1,3 and 5 years were 0.821,0.820 and 0.833,respectively.In the verification group,the C index was 0.733(95％CI=0.711～0.755),and the AUC values for 1,3 and 5 years were 0.816,0.807 and 0.827,respectively.The calibration curve shows that the predicted values of the nomogram are in good agreement with the observed values.The decision curve shows that the nomogram model has better prediction ability than TNM staging system.Conclusion The constructed dynamic prognosis nomogram of GBC patients has high accuracy and reliability.

ObjectiveTo observe the effects of Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the Haizao Yuhutang （HYT） on oxidative stress in the liver of goiter rats under the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020. MethodA total of 128 male Wistar rats were randomly divided into a blank group， a model group， a euthyrox group （20 μg·kg^-1）， a HYT group （12.06 g·kg^-1）， a HYT without Sargassum （HYT-H） group （9.90 g·kg^-1）， a HYT without Glycyrrhizae Radix et Rhizoma （HYT-G） group （10.26 g·kg^-1）， a HYT without Sargassum and Glycyrrhizae Radix et Rhizoma （HYT-HG） group （8.10 g·kg^-1）， and a Sargassum and Glycyrrhizae Radix et Rhizoma （HG） group （3.96 g·kg^-1）. The blank group was given deionized water by gavage， and the others were given propylthiouracil （PTU） to replicate the goiter pathological model. Euthyrox was taken as a positive control drug， and the rest of the Chinese medicine groups were given the corresponding decoction by gavage， the material was collected 12 hours after the last dose. The serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， and the contents of superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px）， malondialdehyde （MDA）， reactive oxygen species （ROS） in liver tissue were detected in each group. The pathological changes in the liver were observed via hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was utilized to detect the mRNA expressions of Kelch-like Ech-associated protein 1 （Keap1）， nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， p53 and Caspase-3 in liver tissues. Western blot was adopted to detect the protein expressions of Nrf2 and HO-1 in liver tissues in oxidative stress-related signaling pathways. ResultCompared with control group， the model group showed significantly increased serum ALT level and contents of MDA and ROS in liver tissues （P<0.05， P<0.01）， significantly reduced activities of SOD and GSH-Px in the liver （P<0.01）， significantly increased mRNA expression of Keap1 （P<0.01）， and significantly decreased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. Compared with the model group， the HYT group manifested significantly reduced serum levels of AST， ALT， and ALP （P<0.05， P<0.01）， significantly reduced contents of MDA and ROS in liver tissue （P<0.01）， significantly increased the activities of SOD and GSH-Px （P<0.01）， significantly decreased mRNA expressions of Keap1， p53， and Caspase-3 （P<0.01）， and significantly increased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. ConclusionUnder the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020， Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the HYT on oxidative stress in the liver of goiter rats had different effects. The HYT that contains Sargassum and Glycyrrhizae Radix et Rhizoma has a protective effect on the liver of goiter rats， and the effect is better than that of the HG group， the euthyrox group， and the incomplete groups. Its mechanism may be related to activating the Nrf2/HO-1 signaling pathway to alleviate liver oxidative stress and inhibiting the p53/Caspase-3 signaling pathway to reduce hepatocyte apoptosis.

Objective: To describe the distribution characteristics of hypertension among adult twins in the Chinese National Twin Registry (CNTR) and to provide clues for exploring the role of genetic and environmental factors on hypertension. Methods: A total of 69 220 (34 610 pairs) of twins aged 18 and above with hypertension information were selected from CNTR registered from 2010 to 2018. Random effect models were used to describe the population and regional distribution of hypertension in twins. To estimate the heritability, the concordance rates of hypertension were calculated and compared between monozygotic twins (MZ) and dizygotic twins (DZ). Results: The age of all participants was (34.1±12.4) years. The overall self-reported prevalence of hypertension was 3.8%(2 610/69 220). Twin pairs who were older, living in urban areas, married, overweight or obese, current smokers or ex-smokers, and current drinkers or abstainers had a higher self-reported prevalence of hypertension (P<0.05). Analysis within the same-sex twin pairs found that the concordance rate of hypertension was 43.2% in MZ and 27.0% in DZ, and the difference was statistically significant (P<0.001). The heritability of hypertension was 22.1% (95%CI: 16.3%- 28.0%). Stratified by gender, age, and region, the concordance rate of hypertension in MZ was still higher than that in DZ. The heritability of hypertension was higher in female participants. Conclusions: There were differences in the distribution of hypertension among twins with different demographic and regional characteristics. It is indicated that genetic factors play a crucial role in hypertension in different genders, ages, and regions, while the magnitude of genetic effects may vary.

Objective: To describe the distribution characteristics of hyperlipidemia in adult twins in the Chinese National Twin Registry (CNTR) and explore the effect of genetic and environmental factors on hyperlipidemia. Methods: Twins recruited from the CNTR in 11 project areas across China were included in the study. A total of 69 130 (34 565 pairs) of adult twins with complete information on hyperlipidemia were selected for analysis. The random effect model was used to characterize the population and regional distribution of hyperlipidemia among twins. The concordance rates of hyperlipidemia were calculated in monozygotic twins (MZ) and dizygotic twins (DZ), respectively, to estimate the heritability. Results: The age of all participants was (34.2±12.4) years. This study's prevalence of hyperlipidemia was 1.3% (895/69 130). Twin pairs who were men, older, living in urban areas, married,had junior college degree or above, overweight, obese, insufficient physical activity, current smokers, ex-smokers, current drinkers, and ex-drinkers had a higher prevalence of hyperlipidemia (P<0.05). In within-pair analysis, the concordance rate of hyperlipidemia was 29.1% (118/405) in MZ and 18.1% (57/315) in DZ, and the difference was statistically significant (P<0.05). Stratified by gender, age, and region, the concordance rate of hyperlipidemia in MZ was still higher than that in DZ. Further, in within-same-sex twin pair analyses, the heritability of hyperlipidemia was 13.04% (95%CI: 2.61%-23.47%) in the northern group and 18.59% (95%CI: 4.43%-32.74%) in the female group, respectively. Conclusions: Adult twins were included in this study and were found to have a lower prevalence of hyperlipidemia than in the general population study, with population and regional differences. Genetic factors influence hyperlipidemia, but the genetic effect may vary with gender and area.

After one week of adaptive feeding， the animals were pre-administrated with the corresponding drug at the rate of 10 mL·kg^-1 for 3 d. From the 4^th day， after 1 h of administration， Erguotou liquid was administrated at the rate of 15 mL·kg^-1 and the blank group was administrated with the same volume of deionized water to record the drunkenness and sober up time. The administration was lasted for 3 d. One hour after the last administration， the eyeballs were removed and the mice were sacrificed. The concentration of ethanol in serum was determined by gas chromatograph， and the activity of ethanol dehydrogenase （ADH） in gastric mucosa was determined by ultraviolet-vis spectrophotometer. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in gastric mucosa. Serum inflammatory factors were determined by enzyme-linked immunosorbent assay （ELISA）. The mRNA expression of nuclear transcription factor-κB （NF-κB） p65 and NF-κB inhibitory protein α （IκBα） were detected by real-time polymerase chain reaction （Real-time PCR）. ResultAs compared with the normal group， the content of interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） in serum of mice in the model group was increased （P<0.05）， the mRNA expression of NF-κB p65 in gastric mucosa tissues was increased （P<0.01）， and the mRNA expression of IκBα was decreased （P<0.01）. As compared with the model group， the drunkenness time of the omeprazole group， high and medium-dose compatibility groups， and Flos Puerariae group was prolonged （P<0.05）， the sober up time of the high and medium-dose compatibility groups was shortened （P<0.05）， the ethanol concentration in the serum of the high-dose compatibility group was decreased （P<0.05）， the ADH activity in the gastric mucosa of the omeprazole group and high and medium-dose compatibility groups was increased （P<0.05）， the macroscopic injury score of the high， medium， and low-dose compatibility groups and Flos Puerariae group was decreased （P<0.05）， the score of pathological injury in the omeprazole group， high， medium， and low-dose compatibility groups， and Flos Puerariae group was decreased （P<0.01）， the expression of IL-6 in serum of all drug groups was decreased （P<0.05）， the expression of IL-1β in serum of the omeprazole group， high， medium， and low-dose Flos Puerariae groups， and Hoveniae Semen group was decreased （P<0.05）， the expression of TNF-α in serum of high and medium-dose groups was decreased （P<0.05）， the mRNA expression of NF-κB p65 in gastric mucosa tissues of all drug groups was decreased （P<0.05）， and the mRNA expression of IκBα in gastric mucosa tissues of the omeprazole group and high， medium， and low-dose compatibility groups was increased （P<0.05）.

ConclusionFlos Puerariae， Hoveniae Semen， and their compatibility play a role in preventing and treating acute alcoholic gastric mucosal injury in mice， which may be related to the inhibition of the expression of NF-κB signal pathway in gastric mucosa， and the high-dose compatibility group has the optimal effect.

OBJECTIVE: To investigate the inhibitory effects of levofloxacin (LEV) combined with cellulase against bacille CalmetteGuerin (BCG) biofilms in vitro. METHODS: The mature growth cycle of BCG biofilms was determined using the XTT method and crystal violet staining. BCG planktonic bacteria and BCG biofilms were treated with different concentrations of LEV and cellulose alone or jointly, and the changes in biofilm biomass were quantified with crystal violet staining. The mature BCG biofilm was then treated with cellulase alone for 24 h, and after staining with SYTO 9 and Calcofluor White Stain, the number of viable bacteria and the change in cellulose content in the biofilm were observed with confocal laser scanning microscopy. The structural changes of the treated biofilm were observed under scanning electron microscopy. RESULTS: The MIC, MBC and MBEC values of LEV determined by broth microdilution method were 4 μg/mL, 8 μg/mL and 1024 μg/mL, respectively. The combined treatment with 1/4×MIC LEV and 2.56, 5.12 or 10.24 U/mL cellulase resulted in a significant reduction in biofilm biomass (P < 0.001). Cellulase treatments at the concentrations of 10.24, 5.12 and 2.56 U/mL all produced significant dispersion effects on mature BCG biofilms (P < 0.001). CONCLUSION LEV combined with cellulose can effectively eradicate BCG biofilm infections, suggesting the potential of glycoside hydrolase therapy for improving the efficacy of antibiotics against biofilmassociated infections caused by Mycobacterium tuberculosis.

Objective:To compare the prenatal diagnosis and pregnancy outcome of increased nuchal translucency (NT) with or without nuchal cystic hygroma (CH) in fetuses with first-trimester NT ≥5 mm.Methods:Data from 131 fetuses with NT ≥5 mm who received invasive prenatal diagnosis at Guangzhou Women and Children's Medical Center from July 2017 to December 2020 were retrospectively collected and analyzed. Those with a septum in the cyst were grouped as NT with CH group ( n=57), and those without as increased NT without CH group ( n=74). Genetic test results, incidence of structural malformations, survival rate after birth were compared using Chi-square test or Fisher's exact test and non-parametric test. Results:There was no significant difference in the incidence of fetal genetic abnormalities[67.6%(50/74) vs 61.4%(35/57), χ 2=0.54, P=0.464], ultrasonic structural malformations [21.6%(16/74) vs 33.3%(19/57), χ 2=2.26, P=0.133], or in the survival rate (12/14 vs 3/8, P=0.053) between increased NT without CH group and NT with CH group. Conclusions:For increased NT with or without CH, although the two groups had different spectrum of disease, they had a high incidence of chromosomal abnormalities and structural malformations, and both groups had a certain healthy survival rate after birth.

Objective:To investigate the prenatal management for pathogenic copy number variation (CNV) by analyzing the parental origin of CNV and pregnancy outcomes in 56 pedigrees.Methods:This study retrospectively analyzed the information of patients who received interventional prenatal diagnosis and chromosomal microarray analysis (CMA) at Guangzhou Women and Children's Medical Center from January 2015 to December 2020. The cases with pathogenic CNV indicated by CMA and receiving parental CMA for further verification were finally enrolled. Clinical data including prenatal diagnostic indications, chromosomal distribution of the pathogenic fragments and fragment sizes were collected and analyzed using t test. All cases were followed up by telephone and record review. Results:Fifty-six cases were included in this study. Pathogenic CNV in 13 (23.2%, 13/56) fetuses were inherited from one parent (eight from mothers and five from fathers), and mainly located in chromosomes 22 (3/13), 17 (3/11), 16 (2/7), 1 (2/4), and X (3/6) with fragment sizes all less than 3 Mb. The fragment size of inherited pathogenic CNV was significantly smaller than that of de novo CNV [1.69 (1.36-2.22) vs 7.54 (2.11-12.30) Mb, t=3.47, P=0.001]. Among the 43 cases with de novo pathogenic CNV, seven (16.3%) were lost to follow up and 35 (97.2%) terminated the pregnancy. The other one with a 0.58 Mb microruplication at 16p11.2 indicated at 37 gestational weeks gave birth to a baby weighting 2 900 g at 39 gestational weeks and no abnormalities were reported during an eight-month telephone follow-up. Two out of the 13 cases with inherited pathogenic CNV were lost to follow up and six pregnancies were terminated. The other five pregnancies were continued and babies were delivered with no abnormalities during a median follow-up period of 13 (4-15) months. Conclusion:Pathogenic CNV alone should not be the indication for pregnancy termination.

Objective To investigate the effect of IGF1R β subunit mutants sb-IGF1R and ma-IGF1R on the biological behavior of osteosarcoma 143B cells. Methods We designed and constructed sb-IGF1R and ma-IGF1R fragments. They were cloned into adenovirus AdEasy shuttle plasmid, to obtain Ad-sbIGF1R and Ad-maIGF1R. We observed the proliferation, migration and apoptosis of the osteosarcoma cells transfected with Ad-sbIGF1R, Ad-maIGF1R and Ad-IGF1R. The Ad-sbIGF1R, Ad-maIGF1R and Ad-GFP nude mouse models were constructed to evaluate the tumor growth in vitro. Results By plasmid PCR, IGF-1R β subunit mutant was overexpressed in osteosarcoma cells. Ad-sbIGF1R and Ad-maIGF1R significantly inhibited the proliferation and migration of osteosarcoma cells, and promoted cell apoptosis, and inhibited tumor growth in subcutaneous tumor-bearing nude mouse models. Conclusion IGF1R β subunit mutants inhibit the proliferation and migration of osteosarcoma cells and induce cell apoptosis.
