Objective To investigate the correlation between the expression of purinergic ligand-gated ion channel 7 receptor(P2X7R)and connective tissue growth factor(CTGF)in serum and cognitive function and clinical symptoms in patients with schizophrenia.Methods A total of 160 patients with schizophrenia who were diagnosed and treated in Department of Mental Intensive Care of Wuhan Wudong Hospital from January 2021 to January 2023 were collected as the observation group,and 160 healthy volunteers who underwent physical examinations were collected as the control group for the study.According to the Positive and Negative Symptom Scale(PANSS),patients were evaluated for their clinical and psychiatric symptoms(positive and negative symptoms,general pathological symptoms,and additional symptoms).The patients were grouped into a high score group(PANSS total score≥70 points,n=72)and a low score group(PANSS total score＜70 points,n=88).MATRICS consensus cognitive battery(MCCB)was applied to evaluate the cognitive abilities of patients;enzyme-linked immunosorbent assay(ELISA)was applied to detect serum P2X7R and CTGF levels.Spearman method was applied to analyze the correlation between serum P2X7R,CTGF levels and PANSS scores,and MCCB scores in patients with schizophrenia.Results Compared with the control group,the serum levels of P2X7R(610.71±107.83ng/L vs 384.78±80.62 ng/L)and CTGF(1.85±0.36μg/L vs 1.40±0.21μg/L)in the observation group were increased,with differences of statistical significance(t=21.226,13.658,all P＜0.05).The scores of variety items of MCBB of patients with schizophrenia in the observation group were lower than those in the control group,with differences of statistical significance(t=14.845～24.862,all P＜0.05),the positive symptom score(21.10±3.42score),negative symptom score(23.37±5.03 score),general pathological symptom score(39.48±8.11score),additional symptom score(8.26±1.22 score),and PANSS total score(92.21±12.50score)of schizophrenia patients in the high group were higher than those in the low group(13.65±3.04,15.62±3.91 score,30.14±6.15 score,5.20±0.94score,64.61±5.30score),with differences of statistical significance(t=14.576,10.964,8.280,17.915,18.764,all P＜0.05).The serum levels of P2X7R and CTGF in patients with schizophrenia in the high group were higher than those in the low group,with differences of statistical significance(t=12.233,5.923,all P＜0.05).The levels of serum P2X7R and CTGF in patients with schizophrenia were positively correlated with PANSS score(r=0.464～0.580,all P＜0.05),and negatively correlated with MCCB score[r=-0.603～-0.439,all P＜0.05].Conclusion The serum levels of P2X7R and CTGF in patients with schizophrenia are elevated,they are closely related to the clinical symptoms and cognitive function of patients.

A 30-year-old female patient with idiopathic sudden hearing loss was treated with anisodamine hydrobromide injection.After 10 minutes of the intravenous injection of this drug,the patient suffered from hypoptyalism and taste disorder for two days.After the second medication,the patient's taste recovery time was significantly shortened by holding the ice water in mouth compared to the first time.Hypoptyalism and taste disorder were considered to be the adverse drug reaction caused by anisodamine hydrobromide injection.After withdrawal the suspected drug,the patient did not experience any further discomfort since.Although taste disorder is not life-threatening,it directly affect the patient's medication experience and quality of life,clinical awareness and attention of the adverse reactions should be increased.

OBJECTIVES: To examine the changes of intestinal flora in children newly diagnosed with acute lymphoblastic leukemia (ALL) and the influence of chemotherapy on intestinal flora. METHODS: Fecal samples were collected from 40 children newly diagnosed with ALL before chemotherapy and at 2 weeks, 1 month, and 2 months after chemotherapy. Ten healthy children served as the control group. 16S rDNA sequencing and analysis were performed to compare the differences in intestinal flora between the ALL and control groups and children with ALL before and after chemotherapy. RESULTS: The ALL group had a significant reduction in the abundance of intestinal flora at 1 and 2 months after chemotherapy, with a significant reduction compared with the control group (P<0.05). Compared with the control group, the ALL group had a significant reduction in the diversity of intestinal flora before and after chemotherapy (P<0.05). At the phylum level, compared with the control group, the ALL group had a significant reduction in the relative abundance of Actinobacteria at 2 weeks, 1 month, and 2 months after chemotherapy (P<0.05) and a significant increase in the relative abundance of Proteobacteria at 1 and 2 months after chemotherapy (P<0.05). At the genus level, compared with the control group, the ALL group had a significant reduction in the relative abundance of Bifidobacterium at 2 weeks, 1 month, and 2 months after chemotherapy (P<0.05); the relative abundance of Klebsiella in the ALL group was significantly higher than that in the control group at 1 and 2 months after chemotherapy and showed a significant increase at 1 month after chemotherapy (P<0.05); the relative abundance of Faecalibacterium in the ALL group was significantly lower than that in the control group before and after chemotherapy and showed a significant reduction at 2 weeks and 1 month after chemotherapy (P<0.05). The relative abundance of Enterococcus increased significantly at 1 and 2 months after chemotherapy in the ALL group (P<0.05), and was significantly higher than that in the control group (P<0.05). CONCLUSIONS The diversity of intestinal flora in children with ALL is significantly lower than that in healthy children. Chemotherapy significantly reduces the abundance of intestinal flora and can reduce the abundance of some probiotic bacteria (Bifidobacterium and Faecalibacterium) and increase the abundance of pathogenic bacteria (Klebsiella and Enterococcus) in children with ALL.

Objective: To investigate the relationship between body mass index (BMI) and sexual development in Chinese children. Methods: A nationwide multicenter and population-based large cross-sectional study was conducted in 13 provinces, autonomous regions and municipalities of China from January 2017 to December 2018. Data on sex, age, height, weight were collected, BMI was calculated and sexual characteristics were analyzed. The subjects were divided into four groups based on age, including ages 3-<6 years, 6-<10 years, 10-<15 years and 15-<18 years. Multiple Logistic regression models were used for evaluating the associations of BMI with sexual development in children. Dichotomous Logistic regression was used to compare the differences in the distribution of early and non-early puberty among normal weight, overweight and obese groups. Curves were drawn to analyze the relationship between the percentage of early puberty and BMI distribution in girls and boys at different Tanner stages. Results: A total of 208 179 healthy children (96 471 girls and 111 708 boys) were enrolled in this study. The OR values of B2, B3 and B4+ in overweight girls were 1.72 (95%CI: 1.56-1.89), 3.19 (95%CI: 2.86-3.57), 7.14 (95%CI: 6.33-8.05) and in obese girls were 2.05 (95%CI: 1.88-2.24), 4.98 (95%CI: 4.49-5.53), 11.21 (95%CI: 9.98-12.59), respectively; while the OR values of G2, G3, G4+ in overweight boys were 1.27 (95%CI: 1.17-1.38), 1.52 (95%CI: 1.36-1.70), 1.88 (95%CI: 1.66-2.14) and in obese boys were 1.27 (95%CI: 1.17-1.37), 1.59 (95%CI: 1.43-1.78), and 1.93 (95%CI: 1.70-2.18) (compared with normal weight Tanner 1 group,all P<0.01). Analysis in different age groups found that OR values of obese girls at B2 stage and boys at G2 stage were 2.02 (95%CI: 1.06-3.86) and 2.32 (95%CI:1.05-5.12) in preschool children aged 3-<6 years, respectively (both P<0.05). And in the age group of 6-10 years, overweight girls had a 5.45-fold risk and obese girls had a 12.54-fold risk of B3 stage compared to girls with normal BMI. Compared with normal weight children, the risk of early puberty was 2.67 times higher in overweight girls, 3.63 times higher in obese girls, and 1.22 times higher in overweight boys, 1.35 times higher in obese boys (all P<0.01). Among the children at each Tanner stages, the percentage of early puberty increased with the increase of BMI, from 5.7% (80/1 397), 16.1% (48/299), 13.8% (27/195) to 25.7% (198/769), 65.1% (209/321), 65.4% (157/240) in girls aged 8-<9, 10-<11 and 11-<12 years, and 6.6% (34/513), 18.7% (51/273), 21.6% (57/264) to 13.3% (96/722), 46.4% (140/302), 47.5% (105/221) in boys aged 9-<10, 12-<13 and 13-<14 years, respectively. Conclusions: BMI is positively correlated with sexual development in both Chinese boys and girls, and the correlation is stronger in girls. Obesity is a risk factor for precocious puberty in preschool children aged 3-<6 years, and 6-<10 years of age is a high risk period for early development in obese girls.

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.
