Objective:To explore the effect of personalized nutritional support based on nutritional risk screening on nutritional status and prognosis of patients with inflammatory bowel disease.Methods:A total of 100 patients with inflammatory bowel disease admitted to the Department of Gastroenterology, The First Affiliated Hospital of Wenzhou Medical University from January 2021 to September 2022 were selected as the study objects, and were divided into control group and observation group according to the random number method. NRS 2002 nutritional risk screening was performed on all patients. The control group was given routine nursing and nutritional support. On this basis, the observation group received patient-centered personalized nutrition support program shared by doctors and patients. The nutritional status, inflammatory indicators and prognosis of the two groups were compared and observed at admission, discharge, 1 month after discharge, and 3 months after discharge.Results:From admission to 3 months after discharge, albumin, prealbumin, nitrogen balance, triceps skinfold thickness in the two groups were significantly increased ( F = 8.43, 14.32, 10.27, 23.41, 7.66, 8.91, 6.84, 8.90, P < 0.05), while the malnutrition inflammation score was significantly decreased ( F = 4.84, 7.42, P < 0.05). Albumin, prealbumin, nitrogen balance, triceps skinfold thickness in the observation group were significantly higher than those in the control group at 3 months after discharge ( t = 7.95, 17.43, 6.55, 6.72, P < 0.001), and the malnutrition inflammation score was significantly lower than that of the control group ( t = 6.95, P < 0.001). As treatment progressed, the levels of C-reactive protein and fecal calprotectin gradually decreased and the erythrocyte sedimentation rate slowed down in both groups compared with the admission, with statistical significance ( F = 9.03, 11.28, 18.37, 19.20, 32.42, 28.88, P < 0.001). The levels of C-reactive protein and fecal calprotectin and erythrocyte sedimentation rate in the observation group were significantly lower than those in the control group 3 months after discharge ( t = 8.29, 7.99, 10.34, P < 0.001). Patients in the observation group had good compliance with the formulated diet plan, and no related rejection events occurred. The readmission rate of patients in the observation group was significantly lower than that of the control group ( χ2 = 10.18, P < 0.05). Conclusion:Individualized nutrition support programs based on nutritional risk screening can help improve the nutritional status and disease status of patients with inflammatory bowel disease.

Objective To investigate the differences in blood pressure phenotypes,renal pathological changes,and related pathogenic pathways in genetically diverse hypertensive mice obtained from 13 strains.Methods The genotypes of Cckbr+/+,Cckbr+/-and Cckbr-/-were obtained by hybridization of 13 strains of genetically diverse mice with Cckbr-/-mice.Blood pressure was measured with a noninvasive blood pressure analysis system(BP-2000).The expression of CCKBR protein in mouse kidney tissue was detected by Western Blot,and the pathological changes in mouse kidney tissue were detected by hematoxylin-eosin(HE)staining and immunohistochemistry(IHC).The pathogenic pathways related to essential hypertension were screened by RNA sequencing.Results In three specific mouse strains(A/J,LOT,and FIM),the systolic blood pressure(SBP)was significantly different between the Cckbr-/-and Cckbr+/+groups.HE staining and IHC showed that hypertension caused a certain degree of renal injury in the mice.Gene Ontology(GO)and pathway enrichment analysis showed that differentially expressed genes were enriched in metabolic processes and circadian rhythm regulation.Conclusions Genetically diverse mice can effectively simulate the genetic background of the population and provide a new resource for studying the pathogenic genes related to essential hypertension.

Objective: QL1604 is a highly selective, humanized monoclonal antibody against programmed death protein 1. We assessed the efficacy and safety of QL1604 plus chemotherapy as first-line treatment in patients with advanced cervical cancer. Methods: This was a multicenter, open-label, single-arm, phase II study. Patients with advanced cervical cancer and not previously treated with systemic chemotherapy were enrolled to receive QL1604 plus paclitaxel and cisplatin/carboplatin on day 1 of each 21-day cycle for up to 6 cycles, followed by QL1604 maintenance treatment. Results: Forty-six patients were enrolled and the median follow-up duration was 16.5 months. An 84.8% of patients had recurrent disease and 13.0% had stage IVB disease. The objective response rate (ORR) per Response Evaluation Criteria in Advanced Solid Tumors (RECIST) v1.1 was 58.7% (27/46). The immune ORR per immune RECIST was 60.9% (28/46).The median duration of response was 9.6 months (95% confidence interval [CI]=5.5–not estimable). The median progression-free survival was 8.1 months (95% CI=5.7–14.0). Fortyfive (97.8%) patients experienced treatment-related adverse events (TRAEs). The most common grade≥3 TRAEs (>30%) were neutrophil count decrease (50.0%), anemia (32.6%), and white blood cell count decrease (30.4%). Conclusion QL1604 plus paclitaxel-cisplatin/carboplatin showed promising antitumor activity and manageable safety profile as first-line treatment in patients with advanced cervical cancer. Programmed cell death protein 1 inhibitor plus chemotherapy may be a potential treatment option for the patient population who have contraindications or can’t tolerate bevacizumab, which needs to be further verified in phase III confirmatory study.

Objective:To investigate difficult-to-treat sites in patients with psoriasis receiving biological therapy.Methods:Clinical data were retrospectively collected from 73 adult patients with psoriasis in the database of Psoriasis Center, National Clinical Research Center for Skin and Immune Diseases from June 2020 to September 2021, who had received sufficient and standardized treatment with biological agents for ≥ 24 weeks, and were still treated with biological agents at the time of enrolment into this study with the psoriasis area and severity index (PASI) score being 1 - 5 at the time of enrolment into the database of Psoriasis Center. Distribution of psoriatic lesions resistant to biological therapy were analyzed, and differences in refractory sites were compared between different biologics. Chi-square test or Fisher′s exact test was used to analyze differences in the anatomical distribution of residual skin lesions after treatment with different biologics, McNemar test to compare the anatomical distribution of skin lesions before and after biological therapy, and Kruskal-Wallis H test to analyze the association between PASI scores for residual skin lesions and dermatology life quality index (DLQI) scores. Results:After ≥ 24 weeks of sufficient and standardized biological therapy in the 73 patients, refractory skin lesions mostly involved the lower limbs (46 cases, 63.01%) , followed by the scalp (36 cases, 49.32%) and upper limbs (27 cases, 36.99%) ; proportions of patients with residual skin lesions on the face and neck, trunk, upper limbs, lower limbs, hands and feet significantly decreased after biological therapy compared with those before treatment (paired χ2 = 5.14, 7.69, 9.90, 4.17 and 6.13, P = 0.016, 0.003, 0.001, 0.031 and 0.008, respectively) , while there was no significant difference in the proportions of patients with skin lesions on the scalp and genital areas before and after treatment (both P > 0.05) . No significant difference in the anatomical distribution of residual skin lesions was observed between the 13 patients receiving treatment with tumor necrosis factor inhibitors (adalimumab, infliximab, or tumor necrosis factor receptor-antibody fusion protein) and 59 receiving treatment with interleukin-17 (IL-17) inhibitors (secukinumab or ixekizumab) (all P > 0.05) . There was no significant difference in the anatomical distribution of residual skin lesions in the 13 patients before and after the treatment with tumor necrosis factor inhibitors (all P > 0.05) ; in the 59 patients treated with IL-17 inhibitors, the proportions of patients with residual skin lesions on the trunk, upper limbs, hands and feet significantly decreased after treatment (paired χ2 = 4.90, 9.09 and 7.11, P = 0.021, 0.001 and 0.004, respectively) , while there was no significant difference in the distribution of skin lesions on the scalp, face and neck, lower limbs and genital area before and after treatment (all P > 0.05) . Among the 73 patients, the PASI scores for lesions on the upper and lower limbs and the total PASI scores were all associated with the DLQI scores ( H = 7.52, 12.61, 6.75, respectively, all P < 0.05) , and were significantly higher in the patients with DLQI scores of > 10 points than in those with DLQI scores of ≤ 5 points (all P < 0.05) . Conclusions:Biological therapy-resistant psoriatic lesions were mostly located on the scalp, and refractory skin lesions mostly involved the lower limbs, scalp and upper limbs. No significant difference in the anatomical distribution of residual skin lesions was observed between patients treated with tumor necrosis factor inhibitors and IL-17 inhibitors, but IL-17 inhibitors may result in lesion clearance at more anatomical sites compared with tumor necrosis factor inhibitors.

ObjectiveTo explore the sensory processing characteristics of preschool children with autism spectrum disorder （ASD）， and to provide a theoretical basis for early screening and intervention training of ASD. MethodsA total of 215 preschool children with ASD and170 typically developed （TD） children were investigated with a basic situation questionnaire and sensory processing measure （SPM）. The two groups were stratified according to age and gender， and the differences of scores in sensory domains were compared to analyze the sensory processing characteristics of preschool children with ASD. ResultsThe scores of social participation， vision， hearing， touch， taste and smell， body awareness， balance and motion， planning and ideas， and total sensory system in children with ASD were all higher than those in children with TD （all P<0.01）. The highest degree of abnormality was found in hearing and the lowest degree in taste and smell in children with ASD. The results of Spearman correlation analysis showed that in the 4-year-old and 5-year-old children with ASD， the scores of vision （r_s=-0.200， P= 0.033） and hearing （r_s=-0.194， P=0.040） decreased with age. There was no correlation between the scores of other developmental quotients and age （all P>0.05）. Boys and girls with ASD had higher scores in all developmental quotients than TD children （P<0.01）. However， there was no significant gender difference in any developmental quotients of ASD children （all P>0.05）. ConclusionSensory processing abnormalities are common in preschool children with ASD， which are different from those of TD children in multiple sensory domains. Sensory processing abnormalities may be used as an indicator for early screening of ASD， and it is necessary to conduct corresponding intervention training for sensory processing abnormalities in children with ASD.

OBJECTIVES: The incidence of infertility is increasing, more than 30% of them having related abnormal tubal patency. Four-dimensional (4D) hysterosalpingo-contrast sonography (HyCoSy) overcomes the shortcomings of 3D HyCoSy in the diagnosis of tubal patency, showing high specificity and accuracy. In addition, 4D HyCoSy discards iodine allergy and X-ray radiation and possesses easy-operating, contributing to good acceptance in clinical practice. However, there is no research to explore the imaging standards related to the possibility of natural pregnancy after 4D HyCoSy. If a predictive model of postoperative natural pregnancy was established using the analysis of clinical data combined with imaging characteristics of 4D HyCoSy of patients with tubal factor infertility, clinical decision-making can be wisely guided in the future. This study aims to establish a predictive model of natural pregnancy after 4D HyCoSy based on clinical data and imaging characteristics of patients with tubal factor in fertility. METHODS: A retrospective study was conducted for patients who were diagnosed with tubal factor infertility in Hunan Guangxiu Hospital from February 2017 to May 2018. The patients ought to possess complete 4D HyCoSy imaging data and at least one-side-unobstructed fallopian tube. General clinical data and imaging data were collected. Pregnancy outcome was followed up till 3 months after 4D HyCoSy. According to pregnancy outcome, patients were divided into a pregnancy group and a non-pregnancy group. Binary logistic regression was used to analyze the correlation between various variables and natural pregnancy after 4D HyCoSy. The variables with significant difference (P<0.05) in single-factor logistic regression were included in the natural pregnancy probability prediction model. The classification accuracy was further verified with 10-fold cross-validation. RESULTS: A total of 1 085 patients with clinically suspected tubal factor infertility who met the requirements and followed the doctors' prescription were collected. Clinical characteristics (age and duration of infertility) and 4D HyCoSy imaging characteristics (thickness of endometrium from the 3rd to the 7th day after the end of menstruation, visualization of the left fallopian tube, the diffusion of contrast agent around the left ovary, and the diffusion of contrast agent around the right ovary) were independent predictors for natural pregnancy 3 months after 4D HyCoSy. A natural pregnancy probability prediction model was established with the area under the curve (AUC) verified by the 10-fold cross-validation all greater than 0.75, and the best AUC was 0.868. The Q value obtained by the prediction model was the probability of natural pregnancy, and the cutoff value was 0.5. When the Q value was greater than 0.5, it was recommended to attempt natural pregnancy for 3 months, and when the Q value was less than 0.5, in vitro fertilization was adviced. CONCLUSIONS A predictive model for the evaluating probability of natural pregnancy in women with tubal factor infertility after 4D HyCoSy is successfully established based on the analysis for clinical data and imaging characteristics. This model shows a great potential in assisting clinical decision making.

Objective: To describe the status of cognition about colorectal cancer and the screening and its relevant factors among first degree relatives of hereditary colorectal cancer patients in Guangzhou. Methods: Totally 274 subjects were investigated by a self-designed demographic questionnaire and the Chinese version of Cognitive Questionnaire for Colorectal Cancer and were analyzed by chisquare test, rank sum test and logistic regressive. Results: 60.2% (165/274) cases had a high level of cognition about colorectal cancer, 23.7% (65/274) had middle level of cognition about colorectal cancer and 16.0% (44/274) had a low level of cognition about colorectal cancer. Multivariate logistic regression analysis showed that age, sex, degree of education, marital status, family income, medical insurance and the number of cancer patients in his family were related factors (P<0.05). People who were young, female, highly educated, high family income, single, public/urban health insurance, commercial insurance and with more than 4 relatives suffering from colorectal cancer have higher cognitive level. Conclusions The level of cognition about colorectal cancer among first degree relatives of hereditary colorectal cancer patients was a little high. Medical staff should pay attention to relevant factors of health belief in subjects and develop targeted intervention to improve the level of cognition among these subjects and to promote their screening behavior.

OBJECTIVE To assess the performance of non-invasive prenatal testing (NIPT) based on massive parallel sequencing. METHODS A total of 10 275 maternal blood samples were collected. Fetal chromosomal aneuploides were subjected to low coverage whole genome sequencing. Patients with high risks received further prenatal diagnosis. The outcome of all patients were followed up. RESULTS High-throughput sequencing detected 72 pregnancies with fetal autosomal chromosomal aneuploidy, including 57 cases of trisomy 21, 14 cases of trisomy 18, and 1 case of trisomy 13. The positive predictive value for trisomies 21 and 18 were 98.25% and 91.67%, respectively. Comparing its performance in intermediate or high risk pregnancies, advanced maternal age pregnancies and volunteering to test pregnancies, the positive predictive value were 100%, 95%, 90% and 50%, respectively. The follow up result was only 1 case of 21 trisomy false negative with high risk. For the 56 cases of trisomy 21, the high risk group accounted for 55%, advanced maternal age accounted for 29%, the intermediate risk referred to 14%, the volunteering to test group accounted for 2%. CONCLUSION The performance of NIPT for trisomies 21, 18 and 13 was satisfactory. The method can be used for women with advanced gestational age. NIPT has offered an ideal secondary screening method for those with an intermediate or high risk, and can reduce the rate of birth defects.
