Objective To investigate the efficacy and safety of Chinese herbal compound modified Huanglian Wendan Decoction in the treatment of hypertension complicated with sleep disorders of phlegm-heat harassing the interior type.Methods A total of 70 patients with hypertension complicated with sleep disorders of phlegm-heat harassing the interior type were randomly divided into a control group and an observation group,35 cases in each group.The patients in the control group were treated with conventional western medicine,and the patients in the observation group were treated with modified Huanglian Wendan Decoction on the basis of treatment for the control group.The course of treatment covered four weeks.The Clinical Global Impression(CGI)score,traditional Chinese medicine(TCM)syndrome score,Pittsburgh Sleep Quality Index(PSQI)score,blood pressure,and serum levels of homocysteine(Hey),interleukin 6(IL-6),interleukin 10(IL-10)and interleukin 8(IL-8)levels in the two groups were observed before and after treatment.Moreover,the safety of medication was evaluated in the two groups.Results(1)After four weeks of treatment,the CGI score of the observation group was(1.63±0.60)points,which was significantly lower than that of the control group[(2.74±0.82)points],and the difference was statistically significant(P＜0.01).(2)After treatment,the TCM syndrome score,systolic blood pressure,diastolic blood pressure and PSQI score of the two groups were significantly decreased compared with those before treatment(P＜0.01),and the decrease of TCM syndrome score,systolic blood pressure,diastolic blood pressure and PSQI score in the observation group was significantly superior to that in the control group(P＜0.05 or P＜0.01).(3)After treatment,the levels of serum Hcy,IL-6 and IL-8 in the two groups were significantly decreased compared with those before treatment(P＜0.01),and the serum IL-10 level was significantly increased compared with that before treatment(P＜0.01).The decrease of serum Hcy,IL-6 and IL-8 levels and the increase of serum IL-10 level in the observation group were significantly superior to those in the control group(P＜0.01).(4)During the treatment,no treatment-related adverse reactions or complications occurred in the two groups.Conclusion Modified Huanglian Wendan Decoction has certain efficacy on patients with hypertension complicated with sleep disorders of phlegm-heat harassing the interior type.The decoction can not only reduce the blood pressure and serum Hcy level of the patients,but also regulate the level of inflammatory factors with high safety.

Objective:To explore the plasma metabolomic characteristics of children with transfusion-dependent thalassemia(TDT),and reveal the changes of metabolic pattern in children with TDT.Methods:23 children with TDT who received regular blood transfusion in Ganzhou Women and Children's Health Care Hospital in 2021 were selected,and 11 healthy children who underwent physical examination during the same period were selected as the control group.The routine indexes between children with TDT and the control group were compared,and then the metabolic composition of plasma samples from children with TDT and the control group was detected by liquid chromatography-mass spectrometry.An OPLS-DA model was established to perform differential analysis on the detected metabolites,and the differential metabolic pathways between the two groups were analyzed based on the differential metabolites.Results:The results of routine testing showed that the indexes of ferritin,bilirubin,total bile acid,glucose and triglycerides in children with TDT were significantly higher than those in healthy controls,while hemoglobin and total cholesterol were significantly lower(all P＜0.05).However there was no significant difference in lactate dehydrogenase between the two groups(P＞0.05).Compared with the control group,190 differential metabolites(VIP＞1)were identified in TDT children.Among them,168 compounds such as arginine,proline and glycocholic acid were significantly increased,while the other 22 compounds such as myristic acid,eleostearic acid,palmitic acid and linoleic acid were significantly decreased.The metabolic pathway analysis showed that the metabolic impact of TDT on children mainly focused on the upregulation of amino acid metabolism and downregulation of lipid metabolism.Conclusion:The amino acid and lipid metabolism in children with TDT were significantly changed compared with the healthy control group.This finding is helpful to optimize the treatment choice for children with TDT,and provides a new idea for clinical treatment.

OBJECTIVE: To investigate the introduction of vegetables and fruits in 4-8 months old infants, and to describe the maternal and infants' characteristics associated with the introduction of vegetables and fruits. METHODS: Mother-infant dyads (n=228) were recruited from 12 to 16 weeks postpartum and formally entered the study at 4 months of age. Data collected via face to face interview at 4-8 months postpartum, including the timing and types of added vegetables and fruits, as well as a variety of maternal and infant characteristics (n=204). Rank sum test and multiple linear regression were used to analyze the maternal and infant characteristics related to the introduction of vegetables and fruits. RESULTS: The time of introducing vegetables was concentrated at the age of 7 months, and the time of adding fruits was mainly at 6 months. Fruits were added earlier than vegetables (P < 0.001), and the variety of the added fruits was higher than that of vegetables (P=0.045). 48% (n=98) of infants had no more than three types of fruits and vegetables at 8 months. Only 9.8% (n=20) had added more than 10 kinds of fruits and vegetables at 8 months. Green leafy vegetables were the most commonly added vegetable, and apple was the most popular fruit. Compared with women who were 35 years of age or younger, women beyond 35 years old introduced vegetables to their babies 0.6 months later. 4-month-old exclusively breastfed infants had vegetables 0.4 months later than mixed-fed infants. Women with a bachelor's degree or above added 2-3 more types of fruits and vegetables to their babies than those with junior high school education and below. CONCLUSION The adding time of fruits was earlier than that of vegetable. Apples and green leafy vegetables are commonly added. Women with lower educational backgrounds add fewer types of fruits and vegetables to their babies. Mothers who choose exclusive breastfeeding and those over 35 years of age at childbirth add vegetables to their babies later than others. They should be targeted for health promotion programs that aim to improve the intake of fruits and vegetables among infants.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective To investigate the mutation characteristics of drug resistance genes of multidrug-resistant mycobacterium tuberculosis in Wuhan, and to provide evidence for molecular diagnosis of drug-resistant tuberculosis. Methods Whole-genome sequencing was performed on 149 isolates collected from Wuhan Pulmonary Hospital in 2017 to obtain the specific mutation of genotype or subtype of H37Rv and the drug-resistant gene mutation of anti-TB drugs. The correlation between major mutation types and genotypes or subtypes was analyzed. Results Among the 149 strains, the major mutation types of resistance-related genes to common anti-tuberculosis drugs were katG Ser315Thr (65.77%, isoniazid), ropB Ser450Leu (62.42%, rifampicin), rpsL Lys43Arg (46.31%, streptomycin), embB Met306Val (20.13%, ethambutol), pncA -11 T>C (3.36%, pyrazinamide), gyrA Ala90Val (10.07%, ofloxacin) , rrs -1401 A> G (4.70%, second-line injectable drugs), fabG -15C>T (14.09%, ethionamide), and folC Ile43Thr (3.36%, paza-aminosalicylate). Nine strains of ahpC-OxyR mutation (isoniazid resistance compensatory mutation) and five strains of ropC gene mutation (rifampicin resistance compensatory mutation) were found. The mutation frequency of embB Met306Ile of L4 strain was higher than that of L2, and the mutation frequency of rpsL Lys43Arg was lower than that of L2 (P < 0.05). The difference of mutation frequency of other sites was not statistically significant. The mutation frequency of thyA His75Asn in the ancient subtype was higher than that in the modern type (P<0.05). Conclusion The mutation of MDR-TB isolates in Wuhan displays genetic diversity and should be detected by whole genome sequencing rather than targeted molecular approaches, which may miss some mutations. Some mutation types of MDR-related genes are related to the genotype and subtype of the strains.

Objective: To construct a prediction model of pathologic complete response (pCR) in locally advanced rectal cancer patients who received programmed cell death protein-1 (PD-1) antibody and total neoadjuvant chemoradiotherapy by using radiomics based on MR imaging data and to investigate its predictive value. Methods: A clinical diagnostic test study was carried out. Clinicopathalogical and radiological data of 38 patients with middle-low rectal cancer who received PD-1 antibody combined with total neoadjuvant chemoradiotherapy and underwent TME surgery from January 2019 to September 2021 in our hospital were retrospectively collected. Among 38 patients, 23 were males and 15 were females with a median age of 68 (47-79) years and 13 (34.2%) a chieved pCR. These 38 patients were stratified and randomly divided into the training group (n=26) and test group (n=12) for modeling. All the patients underwent rectal MRI before treatment. The clinical, imaging and radiomics features of all the patients were collected, and the clinical feature model and radiomics model were constructed. The receiver operating characteristic (ROC) curves of each model were drawn, and the constructed model was evaluated through the area under the curve (AUC), accuracy, sensitivity, specificity, positive predictive value and negative predictive value. Results: There were no significant differences in age, gender, primary location of tumor and postoperative pathology between the two groups (all P>0.05). Forty-one features were extracted from region of interest in each modality, including 9 first-order features, 24 gray level co-occurrence matrix features and 8 shape features. From 38 patients, 41 features were extracted from each imaging modality of baseline and preoperative DWI and T2WI images, totally 164 features. Only 4 features were preserved after correlation analysis between each pair of features and t-test between pCR and non-pCR subjects. After LASSO cross validation, only the first-order skewness of the baseline DWI image before treatment and the volume in the baseline T2WI image before treatment were retained. The area under the curve, sensitivity, specificity, positive and negative predictive values of the prediction model established by applying these two features in the training group and the test group were 0.856 and 0.844, 77.8% and 100.0%, 88.2% and 75.0%, 77.8% and 66.7%, 88.2% and 100.0%, respectively. The decision curve analysis of the radiomics model showed that the strategy of this model in predicting pCR was better than that in treating all the patients as pCR and that in treating all the patients as non-pCR. Conclusion: The pCR prediction model for rectal cancer patients receiving PD-1 antibody combined with total neoadjuvant radiochemotherapy based on MRI radiomics has the potential to be used in clinical screening or rectal cancer patients who can be spared from radical surgery.

BACKGROUND: It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011. METHODS: A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided). RESULTS: The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107). CONCLUSIONS: The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly. TRIAL REGISTRATION NUMBER NCT03620565, https://register.clinicaltrials.gov.

This project is to study the metabolites of Laportea bulbifera extract in rat feces. After the SD rats were gavaged with the extract(136 g·kg~(-1), according to the crude drug dose), the metabolites in their feces were detected by UHPLC-Q-TOF-MS~E technique, and the obtained mass spectrometry data was combined with UNIFI software for prediction. The prototype components and metabolites in rat feces were identified with reference materials and related literature. A total of 43 metabolites were identified(including 8 prototype components and 35 metabolites). The metabolic pathways mainly include monocaffeoylquinic acid(hydrogenation reduction, ring-opening cracking, sulfation, hydroxylation, glucuronidation), quercetin(O-C2 bond ring-opening cleavage, C2-C3 double bond reduction, rutin carbonylation) and so on. The metabolites and metabolic process of L. bulbifera extract in rat feces were clarified, which provided a basis for the study of the active substances and its mechanism of action.

OBJECTIVETo investigate the role of allograft inflammatory factor-1 (AIF-1) in colorectal cancer (CRC) progression and explore the possible mechanism.

METHODSThe expression levels of AIF-1 in 70 CRC tissues and paired adjacent tissues were detected using immunohistochemistry and Western blotting, and the correlation of AIF-1 expression with the clinicopathological features of the patients was analyzed. In the CRC cell line SW480, the functional role of AIF-1 in regulating tumor progression was investigated by transfecting the cells with an AIF-1-overexpressing plasmid (AIF-1) and a negative control plasmid (NC). EdU proliferation assay and flow cytometry were used to assess the cell proliferation and cell cycle changes; Transwell migration assay and Annexin V-APC/7-AAD apoptosis assay kit were used to analyze the cell migration and apoptosis. The changes in the biological behaviors of the cells were observed after application of SB203580 to block the p38 MAPK pathway. The expression levels of CDK4, cyclin D1, P21, P27, MMP2, MMP9, Bax, Bcl2, Bcl-xl, p38 and p-p38 were detected using Western blotting.

RESULTSAIF-1 was down-regulated in CRC tissues compared with the adjacent normal tissues, and its expression level was positively correlated with lymph node metastasis (P=0.008), TNM stage (P=0.003) and tumor size (P=0.023). Overexpression of AIF-1 in SW480 cells significantly reduced EdU-positive cells and caused obvious cell cycle arrest in G1 phase (P<0.05). AIF-1 overexpression resulted in significantly lowered protein expressions of CDK4 and cyclin D1, enhanced expressions of P21 and P27, attenuated cell migration ability (P<0.001), and decreased protein levels of MMP2 and MMP9. AIF-1 overexpression also induced obvious apoptosis of SW480 cells (P<0.01), significantly increased the protein levels of Bax and p-p38, and decreased the protein levels of Bcl-2 and Bcl-xl; SB203580 significantly attenuated the apoptosis-inducing effect of AIF-1 overexpression.

CONCLUSIONAIF-1 plays the role of a tumor suppressor in CRC by inhibiting cell proliferation, suppressing cell migration and inducing cell apoptosis. AIF-1 overexpression promotes the apoptosis of CRC cells by activating the p38 MAPK pathway.
