A 20-year-old male patient presented to the Department of Dermatology of Peking Union Medical College Hospital with complaints of an 8-year history of facial scarring, swelling of the lower limbs, and a 4-year history of scalp thickening. Physical examination showed thickening furrowing wrinkling of the skin on the face and behind the ears, ciliary body hirsutism, blepharoptosis, and cutis verticis gyrate. Both lower limbs were swollen, especially the knees and ankles. The skin of the palms and soles of the feet was keratinized and thickened. Laboratory examination using bone and joint X-ray showed periostosis of the proximal middle phalanges and metacarpals of both hands, distal ulna and radius, tibia and fibula, distal femurs, and metatarsals.Genetic testing revealed two variants in SLCO2A1, c.1658T > A and c.96+4A > C.Through multidisciplinary consultation, we confirmed the diagnosis of pachydermoperiostosis.

Objective:To explore the relationship between white matter integrity and cognitive function in first-episode children and adolescents with schizophrenia by diffusion tensor imaging (DTI).Methods:Totally 84 children and adolescents with first-episode schizophrenia who were hospitalized in the Department of Child and Adolescent Psychiatry at the Second Affiliated Hospital of Xinxiang Medical University from September 2017 to June 2021 were selected as the study group, and 35 healthy children and adolescents matched with the study group were selected as the control group. Positive and negative symptom scale (PANSS) was used to assess the patient's mental symptoms. Diffusion tensor imaging (DTI) scans were performed, and the structural integrity of white matter fibers in the brain was measured by tract-based spatial statistics (TBSS), with the indicators including fractional anisotropy (FA). The Chinese version of measurement and treatment research to improve cognition in schizophrenia consensus cognitive battery (MCCB) and the Stroop color-word test were used to evaluate the cognitive function of all subjects. SPSS 26.0 software was used to analyse the data by analysis of variance, independent sample t-test, Mann Whitney U-test and Pearson correlation analysis. Results:(1)The FA values of the right superior longitudinal tract (MNI: x=49, y=-40, z=31) and the left corticospinal tract (MNI: x=-27, y=-22, z=-19) in the study group were higher than those in the control group(both P<0.05). The FA values of the bilateral cingulate gyrus (MNI: x=-7, y=25, z=14; x=20, y=-50, z=25) and the occipital part of the corpus callosum radiation line (MNI: x=-19, y=-50, z=21) in the study group were lower than those in the control group(both P<0.05).(2)The trail making test score of the study group was higher than that of the control group( t=4.344, P<0.01), and the scores of the symbol coding, Hopkins verbal learning test-revised( HVLT-R), brief visuospatial memory test-revised(BVMT-R), word fluency test, number span, maze, Stroop word, Stroop color and Stroop color words were lower than those in the control group( t=-13.041--3.204, all P<0.05). (3) The FA value of right cingulate gyrus (hippocampus) was negatively correlated with the number span ( r=-0.269, P=0.023).The FA value in occipital part of the corpus callosum radiation line was positively correlated with the symbol code ( r=0.237, P=0.047).The FA value of the left lower longitudinal bundle was negatively correlated with the Stroop color and maze ( r=-0.289, -0.275; P=0.010, 0.020).The FA value of the right inferior longitudinal fasciculus was negatively correlated with the score of maze ( r=-0.254, P=0.032). The FA value of occipital part of the corpus callosum radiation line was positively correlated with positive symptom score ( r=0.170, P=0.040). Conclusion:Cognitive dysfunction in children and adolescent with first-episode schizophrenia may be related to abnormal white matter integrity in the brain.

Gliomas are the most common central nervous system tumours; they are highly aggressive and have a poor prognosis. RGS16 belongs to the regulator of G-protein signalling (RGS) protein family, which plays an important role in promoting various cancers, such as breast cancer, pancreatic cancer, and colorectal cancer. Moreover, previous studies confirmed that let-7c-5p, a well-known microRNA, can act as a tumour suppressor to regulate the progression of various tumours by inhibiting the expression of its target genes. However, whether RGS16 can promote the progression of glioma and whether it is regulated by miR let-7c-5p are still unknown. Here, we confirmed that RGS16 is upregulated in glioma tissues and that high expression of RGS16 is associated with poor survival. Ectopic deletion of RGS16 significantly suppressed glioma cell proliferation and migration both in vitro and in vivo. Moreover, RGS16 was validated as a direct target gene of miR let-7c-5p. The overexpression of miR let-7c-5p obviously downregulated the expression of RGS16, and knocking down miR let-7c-5p had the opposite effect. Thus, we suggest that the suppression of RGS16 by miR let-7c-5p can promote glioma progression and may serve as a potential prognostic biomarker and therapeutic target in glioma.

The presence of replication-competent HBV DNA in the liver and/or serum of HBsAg-negative individuals is a sufficient and necessary condition for the diagnosis of occult hepatitis B virus infection (OBI). In recent years, Chinese scholars have proposed what is considered a more "rigorous" definition, i.e., on this basis, HBV window period (WP) infection is excluded, which corresponds to a serum HBV DNA level of below the lower limit of detection or a low positive value (< 200 IU/mL). As the definition of WP for HBV infection remains unclear and its duration is highly variable, "HBV DNA < 200 IU/mL" is not the only criterion in OBI patients. Therefore, it is believed that there is still a lack of sufficient basis and operability for the definition of OBI based on "the exclusion of HBV WP infection" and "HBV DNA < 200 IU/mL" as "rigorous" conditions for the diagnosis of OBI.

Objective:To explore the pathway of influencing factors of self-management in elderly patients with type 2 diabetes mellitus (T2DM) based on health belief theory.Methods:It was a cross-sectional study. A total of 210 elderly patients with T2DM admitted to Shanghai 10th People′s Hospital from January 2021 to March 2022 were selected as research subjects.The surveys of general data questionnaire, social support rating scale, the diabetes self-management scale, the health literacy survey scale for patients with chronic diseases, and the self-efficacy scale for patients with diabetes were conducted in all the subjects. The t test and Spearman correlation analysis were used to test the correlation among variables. Results:Social support, health literacy and self-efficacy were positively correlated with self-management scores in these patients ( r=0.380, 0.392, 0.274, all P<0.001). Univariate analysis showed that there were statistically significant differences in self-management among patients with different age, education level, physical exercise, medical payment method, family history and sleep quality (all P<0.05). Path analysis showed that the mediating effect of social support in the relationship between health literacy and self-efficacy was significant (95% CI: 0.014-0.117), social support, self-efficacy and health literacy directly affected self-management( β=0.25, 0.27, 0.35, all P<0.01). Self-efficacy and health literacy also positively affected self-management through multiple mediators of social support ( β=0.16, 0.27, both P<0.01). Conclusion:Social support, self-efficacy and health literacy mediate in the self-management of elderly patients with T2DM complicated with chronic complications and interact with each other.

Objective:To investigate the value of CT features in predicting visceral pleural invasion (VPI) in clinical stage ⅠA peripheral lung adenocarcinoma under the pleura.Methods:The CT signs of 274 patients with clinical stage ⅠA peripheral lung adenocarcinoma under the pleura diagnosed in Changzheng Hospital of Naval Medical University from January 2015 to November 2021 were retrospectively analyzed. According to the ratio of 6∶4, 164 patients collected from January 2015 to August 2019 were used as the training group, and 110 patients collected from August 2019 to November 2021 were used as the validation group. The maximum diameter of the tumor (T), the maximum diameter of the consolidation part (C), and the minimum distance between the lesion and the pleura (DLP) were quantitatively measured, and the proportion of the consolidation part was calculated (C/T ratio, CTR). The CT signs of the tumor were analyzed, such as the relationship between the tumor and the pleura classification, the presence of a bridge tag sign, the location of the lesion, density type, shape, margin, boundary and so on. Variables with significant difference in the univariate analysis were entered into multivariate logistic regression analysis to explore predictors for VPI, and a binary logistic regression model was established. The predictive performance of the model was analyzed by receiver operating characteristic curve in the training and validation group.Results:There were 121 cases with VPI and 153 cases without VPI among the 274 patients with lung adenocarcinoma. There were 79 cases with VPI and 85 cases without VPI in the training group. Univariate analysis found that the maximum diameter of the consolidation part, CTR, density type, spiculation sign, vascular cluster sign, relationship of tumor and pleura and bridge tag sign between patients with VPI and those without VPI were significantly different in the training group( P<0.05). Multivariate logistic regression analysis found the relationship between tumor and pleura [taking type Ⅰ as reference, type Ⅱ (OR=6.662, 95%CI 2.364-18.571, P<0.001), type Ⅲ (OR=34.488, 95%CI 8.923-133.294, P<0.001)] and vascular cluster sign (OR=4.257, 95%CI 1.334-13.581, P=0.014) were independent risk factors for VPI in the training group. The sensitivity, specifcity, and area under curve (AUC) for the logistic model in the training group were 62.03%, 89.41% and 0.826, respectively, using the optimal cutoff value of 0.504. The validation group obtained an sensitivity, specifcity, and AUC of 92.86%, 47.06%, and 0.713, respectively, using the optimal cutoff value of 0.449. Conclusion:The relationship between the tumor and the pleura and the vascular cluster sign in the CT features can help to predict visceral pleural invasion in the clinical stage ⅠA peripheral lung adenocarcinoma under the pleura.

Objective:To compare the therapeutic effect of polysaccharide iron complex capsule and Shengxuening tablet on renal anemia in maintenance hemodialysis (MHD) patients.Methods:Patients who received MHD treatment from April to June 2016 in our dialysis center and met the criteria for iron deficiency anemia were block-randomly divided into two groups: the polysaccharide-iron complex group and the Shengxuening group. Blood routine, iron metabolism biomarkers and biochemical exams were measured before treatment and at the 1st, 2nd and 3rd months after treatment, and the incidence of adverse reactions were recorded. The compliance rate of the two groups was observed and compared, and the block-randomized-statistical methods were used to compare the clinical data of the two groups before and after treatment, and cost-benefit analysis was also conducted.Results:Thirty patients in each group completed follow-up. After three months of treatment, the blood routine and iron metabolism indicators of the two groups were improved. Compared with the Shengxuening group, the polysaccharide iron complex group had higher therapeutic efficiency, and the levels of hemoglobin, transferrin saturation and serum ferritin were higher, and lower use of recombinant human erythropoietin ( P<0.05). The other indexes such as red blood cell (RBC), hematocrit (HCT) levels and the effective rate of anemia correction, the effective rate of iron therapy, the effective rate of iron therapy between the two groups were similar. Cost-benefit analysis suggested that the use of polysaccharide iron complexes to treat anemia has lower costs and higher benefits ( P<0.05). Conclusions:Polysaccharide iron complex capsule can better correct anemia and improve iron metabolism, and has low cost-effectiveness, which can effectively reduce medical insurance expenditure. It is a good iron supplementing method in addition to intravenous iron supplement.

Objective:To investigate the compliance of statins and influencing factors in population with cardiovascular risks in the community.Methods:One hundred and eighty-six residents with cardiovascular disease risks in a community of Tianjin were recruited from June 2017 to October 2017. The Chinese revised version of the compliance Morisky scale was used to assess the compliance, and the influencing factors were analyzed.Results:Among all subjects 119 were prescribed with statins (64.0%,119/186) , of whom 7.6% (9/119) did not take the drug. According to the risk assessment of arteriosclerotic cardiovascular disease (ASCVD) in the next 10 years, among the 110 subjects taking the medicine, there were 18 subjects with intermediate risk and 92 with high risk. The subjects with good compliance accounted for 30.0% (33/110), and those with poor compliance accounted for 70.0% (77/110). Univariate analysis showed that education level, occupation, and drug types were significantly associated with statin compliance ( P<0.05). Multivariate logistic regression analysis showed that higher education level and fewer total drug users were correlated with better compliance ( OR=3.530 and 0.388, P<0.05) . The reasons for subjects not taking medicine were fearing of adverse reactions ( n=6, 6/9) , and thinking no symptoms and no need to have medication ( n=3, 3/9).The reasons of poor medication adherence were thinking no symptoms and no need to have medication ( n=31, 40.2%), thinking ineffectiveness of medication ( n=28, 36.4%), fearing of adverse reactions ( n=16, 20.8%), and economic pressure ( n=2, 2.6%). Conclusions:The proportion of residents with poor compliance of statins is high in the community. It is suggested that targeted interventions and standardized management for subjects with cardiovascular risks should be conducted based on the related factors found in the study.

Objective:To evaluate the effect of general practice service based on network platform in health management of patients with multiple chronic conditions (MCC).Methods:Based on network platform, the general practitioners provided health management service for 626 MCC patients in a petrochemical company in Panjin city of Liaoning province from June 2015 to June 2016. The individualized health management plan included health counseling, diet and exercise guidance, health information delivery, health file establishment, and rational medication guidance. After intervention the patient activeness, quality of life, clinical variables were evaluated.Results:Ninety participants dropped out of study (14.38%, 90/626), the questionnaire survey was conducted in rest 536 participants. After 1-year intervention, the scores of physical functioning, role-physical, general health, vitality, social functioning, role-emotional, mental health, and total scores in SF-36 were significantly increased ( F=12.350, 13.215, 10.515, 29.114, 42.972, 10.951, 89.783 and 33.311, respectively, all P<0.05); the values of BMI, waist, systolic and diastolic blood pressure, total cholesterol, triglycerides, low density lipoprotein cholesterol, fasting blood glucose were significantly decreased( F= 30.039, 33.849, 7.152, 27.453, 59.938, 214.270, 73.488 and 62.014, respectively, all P<0.05); the values of high density lipoprotein cholesterol were markedly increased ( F=16.491, P<0.01); the overall scores of activation were increased ( F=9.471, P<0.01), the level of activation was changed (χ 2=16.183, P<0.05); but there was no change in body pain ( F=1.486, P=0.227). There was a weak correlation between patient activation and the general health ( r=0.099, P=0.013), vitality ( r=0.101, P=0.011), mental health ( r=0.099, P=0.013). Conclusion:General practice service based on network platform is feasible and effective for patients with multiple chronic conditions, after the implementation, the activation and the health outcomes are improved significantly.

Objective: To determine the clinical benefits of internal mammary sentinel lymph node biopsy (IM-SLNB) acquired by breast cancer patients with clinically positive axillary lymph node (ALN), and further optimize the IM-SLNB indications. Methods: All primary breast cancer patients with clinically positive ALN from February 2014 to September 2017 were prospectively recruited in this study. IM-SLNB was performed under the guidance of the modified injection technique. The success rate and visualization rate of IM-SLNB, metastatic rate of internal mammary sentinel lymph node (IMSLN) and its related factors were analyzed, and the clinical benefits were accessed according to the current guidelines. Results: Among 126 patients, all of 94 patients (74.6%) who showed internal mammary drainage successfully underwent IM-SLNB. The incidence of internal mammary artery bleeding and pleural lesion were 4.3%(4/94) and 9.6%(9/94), respectively. The metastatic rate of IMSLN was 38.3% (36/94), which was significantly associated with the number of positive ALN (P<0.001) and tumor size (P=0.024). The lymph node staging of 94 patients who underwent IM-SLNB was more accurate. Among them, 36 cases with positive IMSLN underwent internal mammary radiotherapy (IMRT), while the other 58 cases with negative IMSLN avoided radiotherapy. Conclusions IM-SLNB should be routinely performed in patients with positive ALN. IM-SLNB can provide more accurate staging and guide tailored IMRT to benefit more breast cancer patients.
