Objective:To analyze the clinical features of pachydermoperiostosis (PDP) and improve its diagnostic level.Methods:A retrospective analysis was conducted on the clinical data of four patients with PDP treated at Sun Yat-sen Memorial Hospital, Sun Yat-sen University from 2015 to 2023, including clinical manifestations, laboratory tests, imaging examinations, and genetic testing results.Results:All four patients were male with an average onset age of 15 years old (ranging from 9 to 18 years old). One patient′s uncle had PDP, and another patient′s parents were consanguineous, though neither parent showed signs of PDP. All four patients exhibited clubbing, skin thickening, and acne; three had frontal bossing and deepened nasolabial folds; two showed scalp sulci changes on head MRI, and all had periosteal thickening of the phalanges visible on X-ray. One patient accompanied with hypokalemic nephropathy, and another had gastric ulcer. One patient underwent whole exome sequencing test which revealed a homozygous mutation, SLCO2A1 gene c.1406C>T, leading to a protein change p.Pro469Leu. Computational tools REVEL, SIFT, and Polyphen2 predicted this variant as deleterious.Conclusion:In addition to skin thickening, frontal bossing, scalp sulci changes, clubbing, and periosteal proliferation, patients with PDP may also present with hypokalemic nephropathy and gastric ulcer. The SLCO2A1 gene c.1406C>T mutation may be pathogenic.

Objective To analyze the risk factors for delayed hemorrhage in patients with early gastric carcinoma(EGC)after endoscopic submucosal dissection(ESD),as well as to explore the predictive value of predictive models.Methods The clinical data of 386 EGC treated with ESD patients from July 2019 to March 2024 were retrospectively analyzed.They were followed up for a short period of time(24 h～30 d postoperatively)after ESD,and were divided into the group of occurrence(50 cases)and the group of non-occurrence(336 cases)according to the occurrence or non-occurrence of delayed hemorrhage.To understand the clinical data of the patients,multivariate Logistic regression was used to analyze the risk factors for delayed hemorrhage in patients with EGC after ESD,and plot receiver operating characteristic curve(ROC curve)to analyze the predicted value.Results The proportions of cardia gastric fundus,lesion diameter ≥ 3 cm,submucosa with fibrosis,coarse blood vessels,and having ulcer or scar in the occurrence group were significantly higher than those in the non-occurrence group,the differences were statistically significant(P＜0.05).The results of multivariate Logistic regression analysis(with an introduction level of 0.05)showed that the lesion location was cardia-gastric fundus(OR=1.088,95％CI:1.040～1.138),the diameter of the lesion was ≥3 cm(OR=1.095,95％CI:1.057～1.135),and fibrosis under the mucosa(OR=1.130,95％CI:1.061～1.203),thick blood vessels under the mucosa(OR=1.177,95％CI:1.116～1.241),and the presence of ulcer or scar(OR=1.082,95％CI:1.057～1.108)were the risk factors for the occurrence of delayed hemorrhage in patients with EGC after ESD(P＜0.05).A prediction model was established:Logit(P)=-9.238+Location of lesion as cardia-gastric fundus × 0.084+Diameter of lesion ≥ 3 cm× 0.091+Submucosal with fibrosis × 0.122+Submucosal with thick blood vessels × 0.163+Ulcer or scar×0.079(P＜0.05),the likelihood ratio test yielded x2=131.09,DF=8,P＜0.05,which indicated that the constructed prediction model was valid.Hosmer-Lemeshow goodness-of-fit test showed a good model fit(P＞0.05).The ROC curve showed an area under the curve(AUC)value of 0.929 at a cutoff value of 12.00,with a sensitivity of 88.00％(95％CI:0.757～0.955)and a specificity of 83.04％(95％CI:0.780～0.869).Conclusion Postoperative delayed hemorrhage in patients with EGC treated with ESD is associated with cardia-gastric fundus,lesion diameter ≥3 cm,submucosal fibrosis,thick blood vessels,and the presence of ulcer or scar,and the prediction value of the prediction model constructed accordingly is good.

OBJECTIVE: To explore the clinical and genetic characteristics of a Chinese pedigree affected by glycogen storage disease (GSD) type Ia with gout as the first manifestation. METHODS: Clinical and biochemical data of the pedigree were collected. Available members of the pedigree were subjected to gene sequencing, and the result was analyzed by bioinformatics software. The pedigree was followed up for five years. RESULTS: The proband was a young female manifesting recurrent gout flare, hypoglycemia, and hypertriglyceridemia. One of her younger brothers also presented with dysplasia and hepatic adenoma. Gene sequencing revealed that the proband and her younger brother both harbored c.1022T>A (p.I1e341Asn) and c.230+5G>A compound heterozygous variants of the G6PC gene , which were inherited from their father and mother, respectively. Among these, the c.230+5G>A is an intron region variant which was unreported previously, and bioinformatics analysis showed that it may impact mRNA splicing of the gene. The proband was treated with raw corn starch, allopurinol, and fenofibrate. Gout was well controlled, and she had given birth to a baby girl without GSD. CONCLUSION GSD Ia should be considered among young gout patients with hypoglycemia and hepatomegaly, for which gene sequencing is warranted. GSD Ia has a good prognosis after comprehensive treatment with diet and medicine.

Objective:To improve the awareness of cholesterol crystal embolism syndrome (CCE) inrheumatologists.Methods:The clinical characteristics of 40 Chinese CCE patients admitted to our department (one case) were summarize and in the literature (thirty-nine cases) were reviewed.Results:Among these 40 patients, 87.5%(35/40) were male and the mean age was (68±6) years. All patients suffered from athero-sclerosis and 87.5%(35/40) of them had precipitating factors such as endovascular intervention, vascular surgery, anticoagulant, or thrombolytic therapy. The clinical manifestations included renal insufficiency (90.0%, 36/40), blue toe syndrome (82.5%, 33/40), ulceration or gangrene (25.0%, 10/40), and livedo reticularis (15%, 6/40). Acute phase reactant was tested in 25 cases, of whom 84.0%(21/25) showed elevated C-reactive protein (CRP) and 56.0%(14/25) showed elevated erythrocyte sedimentation rate (ESR).Conclusion:Rheumatologists should be alert that CCE is one of the differential diagnosis of systemic vasculitis, especially for patients with severe atherosclerosis.

Objective: Tracking the information on 1.69 million fetal cases across Guangxi Zhuang Autonomous Region (Guangxi) so as to study the occurrences of total and major birth defects in order to evaluate the ability on related prevention and control programs in Guangxi. Methods: Using the self-developed "Gui Women’s System" to establish a database of 1.69 million fetal cases in Guangxi and to analyze the distribution of time, space and population, as well as the outcomes of pregnancy, using the big data. Results: During the 29 months of observation, the overall live birth rate was 99.25%, with stillbirth rate during pregnancy as 0.44%, stillbirth rate during birth as 0.02%, and the 0-6 days mortality rate as 0.14%. The total detection rate on birth defects was 197.63/10 000; the incidence rate was 103.04/10 000, the birth rate was 102.55/10 000. The overall discovery rate of major birth defects was 48.33/10 000, with the incidence rate as 783 000, the birth rate as 0.58/10 000. The discovery rates of major birth defects in 14 cities were between 35 and 68/10 000, and the birth rate dropped significantly to less than 1.00 in 10 000. Nationalities showed that the number of pregnant women with birth defects more than 50 000 would include Hui (9.68/10 000), Yao (9.57/10 000), and Jing (9.37/10 000). With the increasing age of gestation, number of birth defects, incidence of major birth defects also increased. Ninety-five percent of the major birth defects were found within <28 weeks and with the top 5 kinds of major birth defects as complicated congenital heart disease (9.11/10 000), alpha thalassemia (8.36/10 000), and 21-trisomy syndrome (7.85/10 000), beta thalassemia (5.32/10 000) and fetal edema syndrome (4.92/10 000). The top 5 major birth defects appeared as complicated congenital heart disease (9.11/10 000), alpha thalassemia (8.36/10 000), and 21-trisomy syndrome (7.85/10 000), beta thalassemia (5.32/10 000) and fetal edema syndrome (4.92/10 000). Conclusion Programs leading to increase the rate on discovery of major birth defects were fundamental in effectively reducing the major birth defects.

Objective To investigate the efficacy and safety of Shuganjieyu capsule combined with repetitive transcranial magnetic stimulation (rTMS) in the treatment of depression.Methods Eighty outpatients and inpatients with depression who sought medical care in the Department of Mental Health,Second Hospital Affiliated to Lanzhou University were randomly divided into 2 groups,the study group and the control group,each consisting of 40 patients.The study group was treated with Shuganjieyu capsule combined with rTMS,while the control group received selective serotonin-reuptake inhibitors (SSRIs).Clinical efficacy and rate of adverse reactions were evaluated before treatment and 1,2,4 and 6 courses after treatment,by using Hamilton Depression Scale (HAMD) and Treatment Emergent Symptom Scale (TESS).Results After 4 courses of treatment,total efficacy rate of the study group was 92.5％,while that of the control group was 90.0％.No statistical significance could be noted when comparisons were made between them (P ＞ 0.05).After 1 to 2 courses of treatment,HAMD scores of the study group were significantly lower than those of the control group (P ＜ 0.05).However,after 3 and 6 courses of treatment,there were no statistical differences in treatment efficacy (P ＞ 0.05).After 6 courses of treatment,the descending rate in the severe depression patients of the study group was (57.0 ± 17.0) ％,which was obviously lower than that of the control group (62.0 ± 19.0) ％.Statistical significance could be noted when comparisons were made between them (P ＜ 0.05).Evaluations of TESS scores in the 1st,2nd,4th,and 6th week after treatment indicated that the rate of adverse reactions in the control group was 42.5％,which was significantly higher than that of the study group (7.5％).Statistical significance could be found when comparisons were made between them (P ＜ 0.01).Conclusion Treatment by ShuganJieyu capsule combined with repetitive transcranial magnetic stimulation (rTMS) has the advantages of faster efficacy,better safty and less adverse reactions in the treatment of depression,and could produce better effect on those patients with mild and moderate depression.
