This study was aimed to explore factors related to microalbuminuria of early stage of diabetic nephropathy (DN). Through epidemiologic survey, syndrome data of patients with early stage of DN were collected. The analysis was made on relationship between MAU (strain) of early stage of DN patients and the influencing factors (variable) with logistic regression analysis. The influencing factors were investigated in the early stage of DN patients in MAU. The epidemiological study showed a close relationship between factors such as active living style, easy irritability, drinking, old age, long disease course, phlegm and dampness body constitution, qi-stagnation body constitution, purple or dark tongue, thin and rapid pulse, yin deficiency and heat pattern, qi-yin deficiency pattern, cold and dampness pattern with the incidence of early stage of DN. It was concluded that there were 114 cases of early stage of DN with MAU of 20-52 μg·mL-1. The risk factors contained easy irritability, qi-stagnation body constitution, purple or dark tongue, yin deficiency and heat pattern, qi-yin deficiency pattern, as well as cold and dampness pattern. The protective factor contained active living style. There were 95 cases of early stage of DN with MAU of 53-199 μg·mL-1. The risk factors contained drinking, old age, long disease course, phlegm and dampness body constitution, as well as thin and rapid pulse.

OBJECTIVE: To assess the association of genomic instability of epithelial cadherin 1 (CDH1) gene and clinicopathological characteristics of gastric cancer. METHODS: In total 120 paraffin-embedded gastric cancer tissue specimen were prepared, and genomic DNA was extracted. The genomic instability of the CDH1 gene was analyzed by immunohistochemistry and silver staining PCR-single-strand conformation polymorphism. RESULTS: The number of information individuals (heterozygotes) was 98 for the D16S752 locus. The detection rates for microsatellite instability (MSI) and loss of heterozygosity (LOH) at the D16S752 locus and the positive rate of CDH1 protein were 19.39%, 16.33% and 51.02%, respectively. The detection rate of MSI in TNM stages I or II was significantly higher than that in stages III or IV (P<0.05) while the detection rate of LOH was significantly lower than that in stages III or IV (P<0.05). The positive rate of CDH1 protein in TNM stages III or IV was significantly lower than that in stages I or II (P<0.05). The detection rate of MSI of cases with lymph node metastasis was significantly lower than that of without lymph node metastasis (P<0.05) while the detection rate of LOH was significantly higher than that without lymph node metastasis (P<0.05). The positive rate of CDH1 protein in patients with lymph node metastasis was significantly lower than that in patients without lymph node metastasis (P<0.05). The positive rate of CDH1 protein in MSI-positive group was significantly higher than that in MSI-negative group (P<0.05), and the positive rate of CDH1 protein in the LOH-positive group was significantly lower than that the LOH-negative group (P<0.05). CONCLUSION The genomic instability of the CDH1 gene is associated with the progression of gastric cancer. MSI at the D16S752 locus may be used as a molecular marker for early gastric cancer, while LOH at this locus mostly occurs in advanced gastric cancer and can be regarded as an effective indicators for malignancy evaluation and prognosis.

Objective To investigate the effects of miR-325-3p on the EMT, invasion and metastasis of gastric cancer cells by targeting CLDN1 gene. Methods We selected human gastric epithelial cell lines GES-1 and gastric cancer cell lines HGC27, SGC-7901, MKN-45 and MGC-803, and detected the expression of miR-325-3p and CLDN1. The targeting relation between miR-325-3p and CLDN1 were verified by dual luciferase report experiments, and the expression of miR-325-3p and CLDN1 in gastric cancer cells were intervened. qRT-PCR and Western blot were adopted to detect N-cadherin, vimentin and MMP2 expression in cells. CCK-8 assay, Transwell assay, flow cytometry were utilized to detect cell proliferation activity, invasion and apoptosis, respectively. Results Compared with GES-1 cells, miR-325-3p expression was decreased while CLDN1 expression was increased in MGC-803 cells (P < 0.05). CLDN1 was a target gene of miR-325-3p. Overexpression of miR-325-3p could inhibit the proliferation, invasion and EMT of gastric cancer cells, while promote the apoptosis of gastric cancer cells. However, the inhibition of miR-325-3p had the opposite effect (P < 0.05). The overexpression of CLDN1 could reverse the effect of miR-325-3p overexpression on the biological behavior of gastric cancer cells. Conclusion miR-325-3p can suppress CLDN1, inhibit the invasion, metastasis and EMT while promote the apoptosis of gastric cancer cells. miR-325-3p is expected to be a new target in gastric cancer treatment.

Objective:To study the clinical characteristics of ureaplasma urealyticum (UU) infection in preterm infants with gestational age <34 weeks.Methods:From January 2017 to December 2021, premature infants with gestational age <34 weeks admitted to neonatal department of our hospital were enrolled in this prospective cohort study. UU-DNA from respiratory tract samples were examined using quantitative fluorescence polymerase chain reaction method. The infants were assigned into UU (+) group and UU (-) group. Perinatal factors and clinical characteristics were compared between the two groups.Results:A total of 182 preterm infants were enrolled, including 59 cases (32.4%) in UU (+) group and 123 (67.6%) in UU (-) group. UU (+) group had significantly lower gestational age and birth weight and significantly higher incidences of vaginal delivery, premature rupture of membranes (PROM) >18 h and maternal chorioamnionitis than UU (-) group ( P<0.05). Compared with UU (-) group, UU (+) group had significantly higher leucocyte count, neutrophil count and interleukin-6 at 1, 24 and 72 h after birth ( P<0.05). No significant differences existed in C-reactive protein and procalcitonin between the two groups at each time point ( P>0.05). In UU (+) group, the incidences of intrauterine pulmonary infection and bronchopulmonary dysplasia (BPD) were higher and the incidence of respiratory distress syndrome was lower than UU (-) group ( P<0.05). No significant differences existed in the incidences of intraventricular hemorrhage, periventricular leukomalacia, feeding intolerance, necrotizing enterocolitis, retinopathy of prematurity between the two groups ( P>0.0 5). UU (+) group had significantly longer duration of oxygen therapy than UU (-) group ( P<0.05). No significant differences existed in the duration of invasive mechanical ventilation and hospital stay between the two groups ( P>0.05). Conclusions:Preterm infants <34 weeks with positive UU in respiratory tract secretions have higher incidences of vaginal delivery, PROM>18 h and maternal chorioamnionitis. Leukocyte and neutrophil count and interleukin -6 are higher in these infants. They need prolonged oxygen therapy and have increased risks of intrauterine pulmonary infection and BPD.

【Objective】 To analyze the antibody types of autoimmune hemolytic anemia(AIHA) patients in Panyu district, Guangzhou and track the therapeutic effect of blood transfusion, so as to provide reference for clinical transfusion treatment strategy of AIHA patients. 【Methods】 From January 2021 to October 2023, 96 ambiguous cross-matching blood samples from Blood Transfusion Departments of local hospitals sent to Panyu Central Blood Station were analyzed, and 25 samples of AIHA patients were identified. Then blood group identification, Rh system antigen phenotyping, antibody screening and cross-matching were further performed to analyze the correlation between antibody types and transfusion efficacy in AIHA patients. 【Results】 Among the 25 samples of AIHA patients, 17 showed consistency between forward and reverse blood grouping and 8 showed discrepancy. There were 19 (19/25, 76%) samples incompatible in cross match on the major side, of which 18 (18/19, 94.7%) were positive for direct Coombs test, autoantibodies and non-specific antibodies, and 1 (1/19, 5.3%)was positive for autoantibody and alloantibody.There were 6 (6/25, 24%) samples compatible in cross match on the major side, of which 3 (3/6, 50%) were positive for autoantibodies, 3 (3/6, 50%) were positive for autoantibody and alloantibody. Of the 25 AIHA patients, 20 received blood transfusion treatment and could be traced, and 5 patients did not receive blood transfusion treatment or transferred to other hospitals and could not be traced. Blood transfusion was effective in 11 (11/20, 55%) cases, partially effective in 6 (6/20, 30%) cases, and ineffective in 3 (3/20, 15%) cases. Among the ABO blood group incompatibility samples, transfusion was effective or partially effective in 17 (17/20, 85%) cases. 【Conclusion】 The transfusion efficacy of AIHA patients is not directly related to the results of cross-matching. Under the premise of regulating the autoimmune environment and eliminating the ABO blood group incompatibility caused by unexpected alloantibodies, AIHA patients with incompatible cross-matching can be transfused when necessary, and transfusion of ABO and Rh system antigen homologous blood can improve the safety and efficiency of transfusion.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

To explore the correlation between kynurenine (KYN) metabolites and postpartum depression (PPD), and to provide new possible explanation for the pathogenesis of postpartum depression (PPD).
 Methods: A total of 726 Chinese women, who received cesarean section, were enrolled in this study. PPD was diagnosed with an Edinburgh Postnatal Depression Scale (EPDS) score ≥13. Twenty-four women with PPD and 48 matched women without PPD were randomly selected. The perinatal serum concentrations of KYN, quinolinic acid (QUIN) and kynurenic acid (KYNA) were measured. Subsequently, the puerperants were compared for the differences in the serum concentrations of KYN, QUIN and KYNA at the end of term, day 1 and day 3 after cesarean section, respectively.
 Results: The incidence of PPD was 7.99%. Of clinical characteristics, pressure during pregnancy was significantly different between subjects with or without PPD (P<0.01). Patients with PPD showed significantly increased serum KYN concentration (P<0.05) at the end of term, increased serum QUIN concentration (P<0.05) and decreased KYNA concentration (P<0.05) on the third day after cesarean section as compared with the control women. Furthermore, the KYNA/QUIN ratio was significantly higher in patients with PPD as compared to the control women on the third day after cesarean section (P<0.01).
 Conclusion: The contribution of alterations in plasma levels of KYN, QUIN and KYNA is closely related with the incidence of PPD, and correction of KYNA/QUIN ratio could be a new strategy for the prevention and treatment of postpartum depressive symptoms.
