RESUMO
Objective To analyze the relationship between bone mineral density (BMD) of infants over 6 months of age and exclusive breastfeeding and calcium nutrition guidance during pregnancy in Baoding area, and to provide evidence for clinical application. Methods A total of 308 infants over 6 months of age were selected from Baoding Maternal and Child Health Hospital from January 2020 to January 2023, and their BMD was measured by ultrasound. The level of 25 (OH) D3 in subjects' blood was detected. spearman correlation test was used to analyze the correlation between infant bone mineral density and exclusive breastfeeding and calcium nutritional guidance during pregnancy, and logistics regression model was used to analyze the independent factors affecting infant bone mineral density. Results The level of serum 25 (OH) D3 in normal BMD group was significantly higher than that in abnormal BMD group (P<0.05). The rate of exclusive breastfeeding and the guidance rate of calcium nutrition during pregnancy in normal BMD group were significantly higher than those in abnormal BMD group (P<0.05). There was a significant positive correlation between different bone mineral density and exclusive breastfeeding and calcium nutrition guidance during pregnancy (P<0.05). Serum 25 (OH) D3 level, exclusive breastfeeding rate and calcium nutritional guideline rate during pregnancy were independent protective factors for bone mineral density (P<0.05). Conclusion Bone mineral density (BMD) of infants over 6 months of age is positively correlated with exclusive breastfeeding and calcium nutrition guidance during pregnancy, and exclusive breastfeeding and calcium nutrition guidance during pregnancy are independent protective factors affecting BMD of infants over 6 months of age.

Objective To explore factors influencing non-en bloc resection of endoscopic submucosal dissection(ESD)for colorectal neoplasms.Methods A retrospective analysis was conducted on clinical and pathological data of 1251 patients(1312 lesions)who underwent colorectal ESD from January 2011 to December 2022 and were pathologically confirmed as adenoma,serrated lesion,or early colorectal cancer.Clinical and pathological characteristics were compared between the en bloc resection group and the non-en bloc resection group.Univariate and multivariate logistic regression analyses were performed to identify factors influencing en bloc resection in ESD.Results The average size of the1312 lesions was(25.8±16.3)mm.Among the included lesions,there were728 adenomas(55.5%),193 serrated lesions(14.7%),and 391 early colorectal cancers(29.8%).ESD was completed in 1306 lesions and stopped due to perforation or technical difficulties in6 cases.The en bloc resection rate was89.5%(1174/1312),the complete resection rate was 73.8%(968/1312),and the curative resection rate was 70.6%(926/1312).Multivariate logistic regression analysis revealed that diameter of the lesions≥40 mm(OR =6.329,95%CI:4.278-9.384,P<0.001),negative lifting sign(OR =2.384,95%CI:1.424-3.903,P =0.005),scar location lesions(OR =2.997,95%CI:1.310-6.484,P = 0.023),protruded lesions(OR =8.458,95%CI:2.678-40.453,P =0.008),lateral spreading lesions(OR =5.898,95%CI:1.917-27.796,P =0.025),and hybrid ESD(OR =10.162,95%CI:5.705-19.692,P<0.001)were independent factors influencing en bloc resection of ESD for early colorectal cancer and precancerous lesions.Conclusions Diameter of the lesions≥40 mm,negative lifting sign,scar location lesions,protruded lesions,lateral spreading lesions,and hybrid ESD were significantly associated with non-en bloc resection of ESD for colorectal neoplasms.Strict evaluation should be conducted preoperatively to improve the efficacy of ESD.
RESUMO
OBJECTIVE@#To explore the effects of ultrasound-guided stellate ganglion block (SGB) on perioperative stress response, gastrointestinal hormones and postoperative gastrointestinal function recovery in patients undergoing laparoscopic radical gastrectomy for gastric cancer.@*METHODS@#This study was conducted among 60 American Society of Anesthesiologists (ASA) class II-III patients with gastric cancer (regardless of gender, aged 35-75 years with BMI of 18.5-26 kg/m2) undergoing elective laparoscopic radical gastrectomy. The patients were randomized into experimental group (S group, n=30) and control group (NS group, n=30). In S group, SGB at the C6 level of the right cervical spine was performed under ultrasound guidance 15 min before induction of anesthesia by injection of 7 mL 0.5% ropivacaine; the patients in NS group received injections of normal saline in the same manner. Peripheral venous blood samples were collected before SGB (T1), after surgery (T2), and on the 2nd and 6th days after surgery (T3 and T4) for determination of the levels of motitin (MOT), vasoactive intestinal peptide (VIP), cortisol (COR), and blood glucose (GLU). Intraoperative usage of sufentanil, recovery rate of intestinal sounds at 36, 48, 60, 72, 84 and 96 h after operation and the time of first passage of flatus were recorded and compared between the two groups.@*RESULTS@#There was no significant difference in the total amount of sufentanil consumption between the two groups. Compared with those in NS group, the patients in S group had significant lower COR and VIP levels (P < 0.05) and higher MOT level (P < 0.05) at T2, T3 and T4. Glu level at T2 and T3 was also significantly lower in S group (P < 0.05). The recovery rates of intestinal sounds at 36, 48, 60, 72 and 84 h after surgery were significantly higher (P < 0.05) and the time of the first passage of flatus was earlier in S group than in NS group (P < 0.05).@*CONCLUSION@#In patients with gastric cancer undergoing laparoscopic radical gastrectomy, ultrasound-guided SGB can reduce postoperative stress level, promote the recovery of gastrointestinal hormone secretion, and accelerate postoperative recovery of gastrointestinal functions.

Aim To study the effect of gender differences in C57BL / 6J mice on antigen induced Sjogren's syndrome(SS)model. Methods The submandibular gland protein of C57BL/6J female and male mice was extracted and mixed with the same amount of Freund's complete adjuvant(FCA)for the first three times, the antigen concentration was adjusted to 2.5 g·L-1, mixed with Freund's incomplete adjuvant(FIA)for the fourth time, and the same-sex mouse antigen was injected into the back of mice for a total of four times to induce the mouse SS model. The mouse SS model was induced by multi-point intradermal injection of antigen on the back of mice for four times,the body weight of female and male mice was measured every week, the general condition was observed, the saliva volume of mice was measured at the sixth week of modeling. After the mice were sacrificed, the pathological changes of submandibular gland and the changes of T and B lymphocyte subsets in spleen were detected, and the differences in SS model preparation between female and male mice were compared. Results The SS model of male and female mice was successfully established, and there was no significant difference in general condition, saliva volume, submandibular gland pathology, plasma cells and memory B cells between male and female SS mice. The success rate of SS model was 75% in female mice and 60% in male mice. Compared with normal mice of the same sex, the weight loss of female SS mice was earlier and more obvious than that of male SS mice; the submandibular gland index of male mice was significantly higher than that of female mice. Compared with normal mice of the same sex, the proportion of Th17 and Treg cells in spleen of female SS mice was more statistically significant than that of male SS mice. Conclusions The success rate of SS modeling in female mice is higher than that in male mice. Compared with male SS mice, female SS mice have more significant SS like manifestations and pathological manifestations, which can provide a reference basis for the selection of gender when establishing SS model.
RESUMO
Background: The risk of opportunistic infection in ulcerative colitis (UC) is significantly higher than that in healthy subjects, and has adverse impact on clinical outcome. Aims: To analyze the prevalence of opportunistic intestinal infection in UC patients and explore the risk factors of UC complicated with opportunistic infection. Methods: Clinical data of patients with UC hospitalized in Peking University Third Hospital from January 2012 to December 2020 were collected retrospectively. Information on demography, clinical characteristics, laboratory, endoscopic and pathological findings, as well as the medication histories were recorded; the factors associated with opportunistic intestinal infection were analyzed using univariate and multivariate analyses. Results: A total of 275 UC patients were included, with an opportunistic intestinal infection rate of 26.2%; among which, rates of cytomegalovirus (CMV), Epstein ‑ Barr virus (EBV), fungi, Clostridium difficile, amoeba, and multiple infection were 13.5%, 14.5%, 5.1%, 1.5%, 1.1%, and 9.1%, respectively. Multivariate Logistic analysis demonstrated that severe disease activity (OR=6.517, 95% CI: 1.487‑28.552, P=0.013) and albumin <30 g/L (OR=3.895, 95% CI: 1.590 ‑ 9.544, P=0.003) were independent risk factors for CMV infection. The independent risk factors for EBV infection included severe disease activity (OR=11.260, 95% CI: 2.249‑56.382, P=0.003), albumin <30 g/L (OR=2.548, 95% CI: 1.096‑5.927, P=0.030) and C‑reactive protein (CRP) elevation (OR=1.046, 95% CI: 1.007‑1.086, P=0.019). While for intestinal fungal infection, the risk in patients with chronic relapsing type UC was lower (OR=0.278, 95% CI: 0.087‑0.886, P=0.030). Intestinal multiple infection was mainly composed of viral infection, and the independent risk factors were similar to those of CMV and EBV infection. Conclusions: Most of the opportunistic intestinal infection in UC patients is viral infection. Disease activity, inflammatory response and reduced albumin are risk factors for intestinal viral infection in UC patients, while the risk of fungal infection is only related to clinical subtyping.

RESUMO
The incidence of inflammatory bowel disease (IBD) is increasing year by year, yet lacking specific treatment, which seriously affects patients' health and quality of life. The pathogenesis of IBD has not been fully clarified, the psycho-neuro-endocrine-immune regulation through gut-brain axis may play an important role in the pathogenesis of IBD. Studies have shown that IBD patient has an increased risk of depression. More than 20% of IBD patients have depression, the incidence is about 2-4 times that of general population. Antidepressant therapy has good efficacy in some IBD patients. The possible mechanism includes affecting the gut-brain axis, inhibiting inflammation, improving mood, etc. However, there are few relevant studies, and the value of antidepressant therapy in the treatment of IBD needs to be further confirmed by large-sample randomized controlled studies. This article reviewed the application of antidepressant therapy in IBD.
RESUMO
Objective@#To evaluate the effectiveness of eradication therapy based on Helicobacter pylori (Hp) susceptibility and CYP2C19 genotype in children with refractory Hp infection.@*Methods@#In this prospective observational cohort study, 156 children with Hp refractory to amoxicillin+clarithromycin+omeprazole triple regimen in Baoding Children′s Hospital from December 2017 to May 2018 were enrolled. Ninety-two of them underwent Hp culture and CYP2C19 detection. Seventy-five cases with positive Hp culture were defined as culture successful group and were treated according to Hp susceptibility and CYP2C19 genotype. Seventeen cases with negative Hp culture were defined as culture failed group and were treated only based on the results of CYP2C19 genotype. Sixty-four children who did not have Hp culture and CYP2C19 gene testing were defined as the empirical eradication therapy group and were treated with quadruple regimen (amoxicillin+metronidazole+omeprazole+bismuth). Bacterial resistance, CYP2C19 polymorphism and therapeutic effectiveness between the three groups were compared using chi-square test.@*Results@#Among the 75 positive Hp culture results, 72 (96%) were resistant to clarithromycin, 3 (4%) were resistant to metronidazole, 5 (7%) were resistant to levofloxacin, 5 (7%) were resistant to rifampicin, 1 (1%) was resistant to tetracycline, and none was resistant to amoxicillin and furazolidone. The CYP2C19 polymorphism in 92 patients showed that 43 (47%) were extensive metabolizer (EM), 9 (10%) were poor metabolizer (PM), and 40 (43%) were intermediate metabolizer (IM). In terms of the effectiveness, eradication rate in the culture successful group,culture failed group and empirical eradication therapy group were 99% (74/75), 88% (15/17) and 72% (46/64), respectively (χ2=21.325, P<0.05). The eradication rate in the culture successful group was significantly higher than that in empirical eradication therapy group (χ2=21.005, P<0.05), while there was no difference between empirical eradication therapy group and culture failed group (χ2=1.154, P=0.283).@*Conclusion@#Eradication regimen based on bacterial susceptibility and CYP2C19 genotype should be considered in children with refractory Hp infection.
RESUMO
Hesperetin, an abundant bioactive component of citrus fruits, is poorly water-soluble, resulting in low oral bioavailability. We developed new formulations to improve the water solubility, antioxidant activity, and oral absorption of hesperetin. Two nano-based formulations were developed, namely hesperetin-TPGS (D-α-tocopheryl polyethylene glycol 1000 succinate) micelles and hesperetin-phosphatidylcholine (PC) complexes. These two formulations were prepared by a simple technique called solvent dispersion, using US Food and Drug Administration (FDA)-approved excipients for drugs. Differential scanning calorimetry (DSC) and dynamic light scattering (DLS) were used to characterize the formulations’ physical properties. Cytotoxicity analysis, cellular antioxidant activity assay, and a pharmacokinetic study were performed to evaluate the biological properties of these two formulations. The final weight ratios of both hesperetin to TPGS and hesperetin to PC were 1:12 based on their water solubility, which increased to 21.5- and 20.7-fold, respectively. The hesperetin-TPGS micelles had a small particle size of 26.19 nm, whereas the hesperetin-PC complexes exhibited a larger particle size of 219.15 nm. In addition, the cellular antioxidant activity assay indicated that both hesperetin-TPGS micelles and hesperetin-PC complexes increased the antioxidant activity of hesperetin to 4.2- and 3.9-fold, respectively. Importantly, the in vivo oral absorption study on rats indicated that the micelles and complexes significantly increased the peak plasma concentration (Cmax) from 2.64 μg/mL to 20.67 and 33.09 μg/mL and also increased the area under the concentration–time curve of hesperetin after oral administration to 16.2- and 18.0-fold, respectively. The micelles and complexes increased the solubility and remarkably improved the in vitro antioxidant activity and in vivo oral absorption of hesperetin, indicating these formulations’ potential applications in drugs and healthcare products.

@#Scoliosis seriously affects the physical and mental health of children and adolescents. Without timely screening and intervention,it will lead to increased deformity,decreased labor capacity,cardiopulmonary complications,back pain and even paraplegia. This article reviews screening and intervention strategies for scoliosis at home and abroad. It concludes that there is lack of scoliosis screening in children and adolescents in China,and the screening results are difficult to compare horizontally because of the significant differences between strategies. It is suggested that scoliosis screening should be included in school healthcare work and formulate strategies with higher accuracy and safety. At the same time,three-dimension technology has good prospects in scoliosis screening and intervention,which is worthy of further development.
RESUMO
Objective To investigate the prevalence and molecular features of Cryptosporidium in sheep and goats from Anhui Province and neighboring provinces. Methods A total 832 and 781 fresh fecal samples were collected from seven large-scale sheep farms and ten large-scale goat farms in Anhui Province and neighboring provinces of Henan, Jiangsu and Shandong. The prevalence and species of Cryptosporidium were investigated in the fecal samples from the sheep and goats in the study areas using nested PCR assay based on the Cryptosporidium-specific SSU rDNA gene, and the subgenotypes of C. parvum and C. ubiquitum were characterized by amplification and sequencing of the 60 kDa glycoprotein (gp60) gene. Results The overall prevalence of Cryptosporidium was 5.8% (48/832) in sheep and 8.7% (68/781) in goats in Anhui Province and neighboring provinces, respectively. The SSU rDNA gene-based PCR assay identified C. xiaoi and C. ubiquitum in sheep and C. parvum in goats, and subtyping revealed that all C. ubiquitum subgenotypes belonged to XIIa subtype 2 and C. parvum subgenotypes belonged to IIdA19G1. Conclusion The identification of zoonotic C. ubiquitum XIIa subtype 2 and C. parvum subtype IIdA19G1 suggests that sheep and goats may serve as a potential source for human Cryptosporidium infections.

RESUMO
OBJECTIVE@#To investigate the demographics and diagnostic yield in a cohort of Chinese pediatric patients undergoing colonoscopy in one institution over 12 years.@*METHODS@#The study participants were consecutive patients aged <18 years that underwent their first colonoscopy in the endoscopy center at Peking University Third Hospital between Jan. 1, 2005 and Dec. 31, 2017. Demographic, endoscopic, and pathological findings were collected. According to the age of the patients, they were divided into 0-3 year-old group, 4-6 year-old group, 7-14 year-old group and 15-17 year-old group. The patients were also divided into 2005-2011 group and 2012-2017 group, according to the time of colonoscopy.@*RESULTS@#The cohort consisted of 326 patients, including 205 boys (62.9%) and 121 girls (37.1%). In the study, 31 patients (9.5%) were in 0-3 year-old group, 28 (8.6%) were in 4-6 year-old group, 96 (29.4%) were in 7-14 year-old group and 171 (52.5%) in 15-17 year-old group. The terminal ileum intubation success rate was 90.5% (295/326). No serious complications such as hemorrhage or perforation occurred during the procedures. The cleaning effect was good in 92.3% (301/326) of the patients. A total of 204 patients (62.6%) received a positive diagnosis under colonoscopy. 27.0% (88/326) of the patients was diagnosed as nonspecific colitis or terminal ileitis. 46 (14.1%) with inflammatory bowel disease (IBD) and 39 (12.0%) with polyp. The diseases were significantly different among the different age groups. The highest IBD diagnostic rate was found in 0-3 year-old group (7/31, 22.5%), while the highest polyp finding rate was in 4-6 year-old group (8/28, 28.6%). The number of the patients in 0-3 year-old group was significantly increasing in 2012-2017 group compared with 2005-2011 group (27/191 vs. 4/135, P=0.001), while the terminal ileum intubation success rate was higher (179/191 vs. 116/135, P=0.037). However, comparisons between years 2005-2011 and 2012-2017 showed that neither IBD nor polyp detection rate changed significantly (P=0.850).@*CONCLUSION@#Colonoscopy in pediatric patients was a safe and effective procedure. Colitis or terminal ileitis was the primary finding during colonoscopy while IBD was the second one, and polyp was the third. However, the diagnostic yield did not change significantly. IBD was not as quickly increased in our hospital as it was in South China.

Aim To investigate the protective effect of immunomodulating peptide(PGPIPN) on the acute al-coholic liver injury in mice. Methods Kunming mice were randomly divided into control group, model group,glutataione(GSH) group, PGPIPN low dose group, PGPIPN moderate and high dose groups. The mice were treated with different doses of PGPIPN or GSH for two weeks except control group and model group. The acute alcoholic liver injury model was in-duced by gavage with 56° alcohol for three days. The indices including the activities of AST,ALT in serum, and the contents of TNF-α, MDA, SOD and GSH-Px in liver were examined. Liver histopathological changes were examined by HE staining. Results Compared with control group,the levels of serum ALT,AST and the contents of TNF-α, MDA significantly increased, while the contents of SOD and GSH-Px significantly de-creased in model group. There was hepatocyte apopto-sis and inflammatory cell infiltration in liver tissues. Compared with model group, the activities of serum ALT, AST and the contents of TNF-α, MDA were re-markably reduced in PGPIPN high dose group. The contents of SOD and GSH-Px significantly increased in PGPIPN high dose group. PGPIPN could alleviate the injury of liver. Conclusion PGPIPN has certain pro-tective effect on acute alcoholic liver injury of mice, providing a theoretical guidance.

[Objective]To determine the relationship between maternal serum IL-1, IL-6, IL-8, TNF-a and CRH levels and preterm labor in asymptomatic women at 24 to 28 weeks' gestation. [Methods] We performed a prospective cohort study from January 2015 to December 2017 for asymptomatic women at 24 to28 weeks' gestation and maternal serum. According to the pregnancy outcome, 100 cases of preterm labor were selected as experimental group and another 100 cases of term labor as control group. The levels of serum IL-1, IL-6, IL-8, TNF-a and CRH were measured by ELISA. The partial membranes of all cases were examined pathologically after labor. [Results] The levels of serum IL-1, IL-6 and IL-8 in preterm labor group were significantly higher than those in the control group (P <0.05). The levels of serum IL-6and IL-8 in preterm labor with chorioamnionitis were significantly higher than those without chorioamnionitis and term labor (P < 0.05). The level of IL-1 in preterm labor without chorioamnionitis was significantly higher than that of term labor (P<0.05). The levels of serum TNF-a and CRH had no difference between the groups (P>0.05). Receiver-operating characteristic curves demonstrated that serum IL-1, IL-6 and IL-8 predicted preterm labor. The area under the curve (AUC) of IL-1 was 0.843. The AUC of IL-6 was0.675 and IL-8 was 0.55. [Conclusion] Maternal serum IL-1, IL-6 and IL-8 in asymptomatic women at24 to 28 weeks' gestation are useful markers for prediction of preterm labor.
RESUMO
To characterize the prevalence and species/genotypes of Cryptosporidium spp. in farmed pigs in the north of the Yangtze River in Anhui Province.A total of 500 samples of pig feces were obtained from seven largescale pig farms in the north of the Yangtze River in Anhui Province. PCR and sequences analysis of the small subunit rDNA gene were used to detect and identify the Cryptosporidium species/genotypes.The overall prevalence of Cryptosporidium was 4.8% (24/500). Additionally, Cryptosporidium prevalence was 40.0% in Qianshan and 6.3% in Chuzhou, respectively. No Cryptosporidium infection was found in other sampling areas. The DNA sequence analysis of the SSUrDNA gene revealed that all of the isolates represented C. scrofarum. The Cryptosporidium infection rate (9.1%) of pigs (> 60 days) was significantly higher than the rates of both pigs (< 30 days) and pigs (30–60 days) (both P < 0.01).C. scrofarum in the farmed pigs in the north of the Yangtze River in Anhui Province may be a source of Cryptosporidium infection and pose a potential public health threat to humans and other animals, and therefore, the status should be paid more attention to.
RESUMO
<p><b>OBJECTIVE</b>Traditional Chinese medicine (TCM) is regarded as an important treatment for gastric cancer patients, especially for those in advanced stage. To evaluate the effects of TCM treatment on gastric cancer patients, the authors performed a retrospective study to report the result of the integrated treatment of TCM with chemotherapy for stage IV non-surgical gastric cancer.</p><p><b>METHODS</b>In this study, 182 patients with stage IV and non-surgical gastric cancer were retrospectively analyzed to evaluate the effects of TCM integrated with chemotherapy. Among the 182 cases, 88 cases received integrated therapy consisting of TCM and chemotherapy, while 94 cases received chemotherapy alone. The overall survival and Karnofsky performance status (KPS) score were measured as the main outcome.</p><p><b>RESULTS</b>The median overall survival of the integrated therapy group and chemotherapy group were 16.9 and 10.5 months, respectively. The 1-, 3- and 5-year survival rates of integrated therapy group vs. chemotherapy group were 70% vs. 32%, 18% vs. 4%, and 11% vs. 0%, respectively. There was a significant difference between the two groups (χ= 42.244, P > 0.001). After six-month treatment, KPS scores of the integrated therapy group and the chemotherapy group were 75.00 ± 14.78 and 60.64 ± 21.39, respectively (P > 0.001). The Cox regression analysis showed that TCM treatment is a protective factor for patients' overall survival.</p><p><b>CONCLUSION</b>This study demonstrated that TCM integrated with chemotherapy may prolong overall survival and improve survival rate and life quality of patients with stage IV non-surgical gastric cancer.</p>
