Ulcerative colitis （UC） is a chronic and relapsing inflammatory bowel disease that primarily affects the mucosal layer of the rectum and colon. Its pathogenesis is complex and remains incompletely understood. Endoplasmic reticulum stress （ERS） plays a critical role in cellular responses to external stress and the maintenance of homeostasis， and its abnormal activation is closely associated with the development of various inflammatory diseases， particularly in the pathological process of UC. ERS maintains cellular homeostasis by activating the unfolded protein response （UPR）. However， when ERS is prolonged or excessive， UPR fails to alleviate the stress， leading to epithelial cell death and aggravating the progression of UC. Modulating ERS may serve as a key target for the prevention and treatment of UC， and it is one of the current research hotspots. Traditional Chinese medicine （TCM） has shown significant efficacy in regulating ERS， offering unique therapeutic advantages through multi-target and multi-pathway mechanisms. Recent studies have confirmed that TCM can alleviate ERS， inhibit apoptosis， regulate autophagy， reduce inflammatory responses， and maintain intestinal barrier function to prevent and treat UC. This review summarized the relationship between ERS and UC and discussed the intervention of TCM in regulating ERS for the treatment of UC， aiming to provide new insights and approaches for the treatment of UC with TCM.

Ulcerative colitis （UC）， a chronic， non-specific inflammatory bowel disease with typical symptoms such as abdominal pain， diarrhea， and bloody stools， demonstrates a high relapse rate and difficulty in curing. Sishenwan， first recorded in Internal Medicine Abstract （Nei Ke Zhai Yao）， are a classic prescription for treating diarrhea caused by deficiency of the spleen and kidney Yang. The core therapeutic principle of Sishenwan is warming and tonifying the spleen and kidney， and astringing the intestine and stopping diarrhea. In recent years， Sishenwan have demonstrated distinct advantages in the clinical treatment of UC. The pathogenesis of UC involves multiple factors， including immune dysregulation and gut microbiota imbalance. Although Western medicine is effective in the short term， its side effects， high relapse rate， and resistance associated with long-term use pose substantial challenges. Sishenwan have shown excellent clinical outcomes in the treatment of UC due to deficiency of the spleen and kidney Yang. Modern clinical studies indicate that Sishenwan， used alone or in combination with Western medicine or other Chinese medicine compound prescriptions， significantly improve the clinical efficacy in treating UC due to deficiency of the spleen and kidney Yang. Sishenwan effectively alleviate core symptoms such as mucus， pus， and blood in stools， and persistent abdominal pain， reduce Mayo scores and the relapse rate， and improve patients' quality of life. Research on the material basis reveals that Sishenwan contain multiple active ingredients such as psoralen， isopsoralen， and evodiamine. Mechanism studies indicate that Sishenwan inhibit the inflammatory cascade reactions by regulating the signal network through multiple targets. Sishenwan regulate cellular immunity and restore intestinal immune homeostasis. At the microecological level， Sishenwan promote the intestinal barrier repair through the "microbiota-metabolism-immunity" axis. The current research still needs to be deepened in aspects such as the mining of specific biomarkers for syndromes and the exploration of the collaborative mechanism of traditional Chinese and Western medicine. In the future， a full-chain system covering syndrome differentiation， targeting， and monitoring needs to be constructed for promoting the paradigm transformation of Sishenwan into precision drugs. This review systematically explains the treatment mechanism of Sishenwan regarding the combination of disease and syndrome and its multi-target regulatory characteristics， providing a theoretical basis and transformation direction for the treatment of UC with integrated traditional Chinese and Western medicine.

Objective:To investigate the efficacy of venetoclax-based combined regimen in treatment of adult patients with acute myeloid leukemia (AML).Methods:The data of 50 adult AML (non-acute promyelocytic leukemia) who received venetoclax-based combined regimen in the First Affiliated Hospital of Xiamen University, Dongguan People's Hospital, the First Hospital of Longyan City, Jieyang People's Hospital from December 2018 to May 2021 were retrospectively analyzed. Different doses venetoclax combined with demethylation drugs or low-dose chemotherapy regimen were used to analyze the therapeutic efficacy. The related factors influencing efficacy were analyzed by using logistic regression.Results:The composite complete remission (CR) rate of 50 AML patients was 62.0% (31/50), the overall response rate (ORR) was 76.0% (38/50); 28 patients achieved effectiveness [CR and partial remission (PR)] after the first cycle and could achieve effectiveness by 3 courses of treatment at the latest. Among 50 patients, 28 cases were newly diagnosed AML, the composite CR rate was 60.8% (17/28), ORR was 78.6% (22/28); 22 cases were recurrent and relapsed, the composite CR rate was 63.6% (14/22), ORR was 72.7% (16/22); and there was no statistically significant difference of ORR between the both groups ( χ2 = 0.23, P = 0.743). Logistic regression multivariate analysis showed age was the only independent influencing factor for the treatment effectiveness ( OR = 8.451, 95% CI 1.306-54.697, P = 0.025). The median duration time of patients receiving venetoclax treatment regimen was 4.5 months (1.1-15.0 months); 16 cases who had treatment effectiveness finally relapsed, the median time of maintaining effectiveness was 5 months (1.1-11.0 months). Additionally, the common treatment-related adverse reactions included bone marrow suppression after treatment, followed by some gastrointestinal reactions like nausea, vomiting and stomachache. In addition, no patient stopped medication for more than 1 week due to bone marrow suppression related complications. Conclusion:Venetoclax-based combined regimen shows a good short-term efficacy in treatment of AML. It is also effective and tolerable for elderly patients receiving reduced dose therapy.

Objective: To investigate clinicopathological features and prognostic factors of gastric neuroendocrine tumors (G-NEN). Methods: Clinical and pathological data of patients with G-NEN diagnosed by pathological examination in Chinese PLA General Hospital from January 2000 to June 2018 were retrospectively analyzed in this case-control study. Patients with complicated visceral lesions, other visceral primary tumors, mental disorders and incomplete clinicopathological data were excluded. Finally, 240 hospitalized patients who met the inclusion criteria were enrolled. Physical examination information, tumor characteristics and pathological characteristics of patients were summarized. The Cox regression models were used to analyze the risk factors affecting G-NEN and the survival conditions were described by Kaplan-Meier survival curves and log-rank test. Results: In 240 patients with G-NEN, the mean age was (60.3±10.1) years; 181 were male (75.4%) and 59 females (24.6%); mean tumor diameter was (4.2±2.8) cm; 51 cases (21.2%) were neuroendocrine tumor (NET), 139 cases (57.9%) neuroendocrine carcinoma (NEC), 50 cases (20.8%) mixed neuroendocrine carcinoma (MANEC); 28 cases (11.7%) were G1 low grades, 34 cases (14.2%) G2 medium grades, and 178 cases (74.2%) G3 high grades; tumor infiltration depth T1 to T4 were 44 cases (18.3%), 27 cases (11.2%), 60 cases (25.0%) and 109 cases (45.4%) respectively; 163 cases (67.9%) developed lymphatic metastasis and 46 patients (19.2%) distant metastasis; tumor stage from stage I to stage IV were 55 cases (22.9%), 42 cases (17.5%), 94 cases (39.2%) and 53 cases (22.1%) respectively. Of the 240 G-NEN patients, 223 cases (92.9%) were followed up. The median survival time of the patients was 39.2 (95% CI: 29.1 to 47.5) months. Univariate survival analysis showed that age ≥ 60 years, tumor diameter ≥ 4.2 cm, tumor grade G3, lymphatic metastasis, distant metastasis, and tumor stage III-IV were risk factors for G-NEN patients. Multivariate survival analysis revealed that lymphatic metastasis (HR=1.783, 95%CI: 1.007-3.155, P=0.047) and distant metastasis (HR=2.288, 95% CI: 1.307-4.008, P=0.004) were independent risk factors of the prognosis. Further analysis of the G3 subgroup of G-NEN showed that the 5-year survival rate of NET-G3 was 76.19%, which was significantly higher than that of NEC-G3 and MANEC-G3 (15.60% and 24.73%, P=0.012). Conclusions Most G-NEN patients are in advanced stage at diagnosis. Lymphatic metastasis and distant metastasis indicate poor prognosis. The prognosis of high proliferation NET-G3 patients is better as compared to those of NEC-G3 and MANEC-G3. This classification is worth further attention.

Objective:To investigate the clinical, pathological and genetic characteristics of neonatal alveolar capillary dysplasia with misalignment of the pulmonary veins (ACDMPV).Methods:The clinical manifestations, radiographic examinations, pathology and parental genetic analysis of a newborn with FOXF1 variation induced ACDMPV, who was hospitalized in the Department of Neonatology of Shenzhen Children′s Hospital in January 2020, were extracted and analyzed. Related literature up to March 2020 with the key words of “Alveolar capillaries dysplasia” “Alveolar capillary dysplasia with misalignment of the pulmonary veins” “FOXF1” in PubMed, CNKI, Wanfang, CQVIP database and Leiden Open Variation database (LOVD) were searched.Results:A full-term male newborn （1 hour of age） was admitted due to anal atresia. Surgical repair of anal atresia and omphalocele was performed on the first day of life, and gallbladder absence and Meckel′s diverticulum were identified during the operation. Respiratory distress with hypoxemia developed at about 6 hours of life, and persistent pulmonary hypertension developed and progressed after surgery, with poor response to mechanical ventilation and pulmonary vasodilators. This infant passed away at 26 days of life. Lung biopsy showed decreased alveolar units and thickened interalveolar septa, reduced alveolar capillary density and thickened walls of peripheral pulmonary arteries, and misaligned pulmonary veins adjacent to the pulmonary arterioles, which were consistent with ACDMPV. The whole exome sequencing revealed a heterozygous novel frameshift of FOXF1 gene located in chromosome 16q24.1 c376_377insT; p.(Pro126fs). According to the bioinformatics analysis, this variation was likely to be pathogenic as it was associated with coding disorder of FOXF1 Pro126, resulting in truncation of the encoded protein. This novel variation had not been reported in the human gene mutation database (HGMD), ESP6500siv2_ALL, 1000g2015aug_ALL or dbSNP147 database. Previous 6 literatures reported 54 variants, including 28 missense, 10 nonsense, 11 frameshift, 2 deletion, 1 synonymous, and 2 extensions. Only three of the reported 45 cases （24 males, 21 females） were still alive as of the time of this study.Conclusions:Typically, ACDMPV is a catastrophic disease in neonatal period with high mortality. Lung biopsy and genetic testing should be considered in infants who present with persistent pulmonary hypertension and refractory hypoxemia, especially when combined with extrapulmonary abnormalities.

OBJECTIVETo analyze a case of supernumerary marker chromosome (SMC) with combined genetic techniques and explore its correlation with the clinical phenotype.

METHODSThe SMC was analyzed with G-banded karyotyping, multiplex ligation dependent probe amplification (MLPA), fluorescence in situ hybridization (FISH), and single nucleotide polymorphism array (SNP-array).

RESULTSG-banding analysis indicated that the patient has a karyotype of 47,XX,+mar. MLPA showed that there were duplications of proximal 15q. FISH assay using D15Z4 probes indicated that the SMC was a pseudodicentric chromosome derived from chromosome 15. And SNP-array revealed that there were two extra copies of 15q11-13 region spanning from locus 20 161 372 to 29 071 810.

CONCLUSIONThe duplication of Prader-Willi/Angelman syndrome critical region probably underlies the abnormal phenotype of the inv dup(15) case with a BP3:BP3 rearrangement.

OBJECTIVETo investigate the clinicopathologic features and prognostic factors of gastric neuroendocrine neoplasms(gNENs).

METHODSClinicopathologic data of 104 patients with gastric neuroendocrine neoplasms admitted in Chinese PLA General Hospital between January 2000 and December 2014 were analyzed retrospectively. Tumor proliferation activity classification (G1, G2 and G3) and TNM staging were observed. The clinicopathologic features of the whole group were collected and the univariate and multivariate analysis were determined by Log-rank and Cox proportional hazard model to detect the prognosis-determining features.

RESULTSOf all the patients, 66 cases(63.5%) were neuroendocrine carcinoma, 25 cases(24.0%) were mixed adenoendocrine carcinoma and 12 cases (11.5%) were neuroendocrine tumor. For G grades, 92 cases (88.5%) were G3 grade, 8 cases(7.7%) were G2 grade and 4 cases (3.8%) were G1 grade. TNM staging results showed that stageI( was found in 6 cases (5.8%), stageII(A in 6 cases (5.8%), stageII(B in 9 cases (8.7%), stage III(A in 8 cases (7.7%), stage III(B in 55 cases (52.9%) and stageIIII( in 20 cases (19.2%). For T stage, 7 cases (6.7%) were T1, 12 cases (11.5%) were T2, 24 cases (23.1%) were T3, and 61 cases (58.7%) were T4. Lymph node metastasis occurred in 73 cases (70.2%) and distant metastasis occurred in 20 cases(19.2%). Eighty-six patients were followed up for 6 to 186 months. The median survival was 33.0 months(95% CI: 28.3 to 36.6), and 1-, 3-, and 5-year survival rates were 80%, 49% and 31%. Clinicopathologic features which were considered statistically significant on univariate analysis were selected to Cox proportional hazard model. Univariate analysis showed that risk factors of reducing survival rate included tumor size, pathological type, proliferation activity grades, and depth of invasion (all P<0.05), as well as chromogranin A expression, tumor staging, lymph node metastasis and distant metastasis(all P<0.01). The multivariate analysis showed that the stage of gNEN was the independent risk factor of the prognosis (RR=14.213, 95% CI: 1.316 to 153.524, P=0.029).

CONCLUSIONLate staging is the main clinical feature and a prognostic factor for gNENs.
