The historical development of endogenous wind （内风） is traced with time as the thread， based on the progression of factors such as syndromes， causes of disease， and pathogenesis. It is believed that the concept of wind syndrome originated in The Inner Canon of Yellow Emperor （《黄帝内经》）， encompassing both exogenous wind （外风） and endogenous wind syndrome. Over time， exogenous wind syndrome gradually evolved into mild syndromes and severe syndromes， while endogenous wind syndrome emerged from severe syndromes of exogenous wind. Endogenous wind syndrome has both syndrome and pathogenic attributes， and its theoretical system has gradually become more refined. Based on the theories of ancient and modern medical practitioners， and combining the holistic perspectives with Xiang （象） thinking， it is proposed that endogenous wind has both physiological and pathological distinctions. The physiological endogenous wind refers to the liver's moderate dispersing and regulating function， which helps to distribute qi （气）， blood， and body fluids， while pathological endogenous wind arises from abnormal liver dispersal. Therefore， in clinical practice， different treatment methods， such as tonifying， unblocking， and warming， can be applied according to the differentiation of deficiency and excess in the pathogenesis.

Objective:To explore the high-risk factors affecting the severity of neonatal necrotizing enterocolitis (NEC).Methods:This study involved 153 NEC patients admitted to the Neonatology Department of the Children's Hospital of Soochow University from January 1, 2017, to December 30, 2023. Based on the severity of NEC determined by Bell's criteria, these patients were divided into two groups: mild group (Bell stage Ⅱ, n=70) and severe group (Bell stage Ⅲ, n=83). Clinical data including general conditions, clinical treatment and disease status before the onset of NEC, laboratory test results, and perinatal conditions of the mothers were retrospectively collected. Univariate analysis (rank-sum test and Chi-square test) and multivariate analysis (logistic regression analysis) were used to explore the risk factors affecting the severity of NEC. Results:The proportion of infants with gestational age<37 weeks or birth weight<1 500 g, the rate of antibiotic usage, sepsis or shock were higher in the severe group than in the mild group [91.6% (76/83) vs. 75.7% (53/70); 55.4% (46/83) vs. 34.3% (24/70); 85.5% (71/83) vs. 71.4% (50/70); 55.4% (46/83) vs. 17.1% (12/70); 30.1% (25/83) vs. 8.6% (6/70); with χ 2 values of 7.22, 6.84, 4.57, 23.64, and 10.91, respectively, all P<0.05]. Furthermore, the severe group had a late initiation of breastfeeding and longer durations of peripherally inserted central catheter (PICC) placement and parenteral nutrition [2.00 d (1.00-2.00 d) vs. 1.00 d (1.00-2.00 d); 0.00 d (0.00-18.00 d) vs. 0.00 d (0.00-7.50 d); 14.00 d (5.00-21.00 d) vs. 10.50 d (0.00-18.25 d), with Z values of -2.90, -1.98, and -2.09, respectively, all P<0.05]. (2) Within 48 h before the onset, the severe group had higher proportions of infants with decreased white blood cell count, decreased platelet count, electrolyte imbalance, and metabolic acidosis than the mild group [53.0% (44/83) vs. 14.3% (10/70); 49.4% (41/83) vs. 10.0% (7/70); 38.6% (32/83) vs. 14.3% (10/70); 37.3% (31/83) vs. 14.3% (10/70), with χ2 values of 24.94, 27.38, 11.23, and 10.30, respectively, all P<0.05]. Besides, the levels of procalcitonin and C-reactive protein were higher in the severe group than in the mild group [2.31 ng/ml (0.26-11.71 ng/ml) vs. 0.22 ng/ml (0.00-2.19 ng/ml); 58.50 mg/L (14.34-125.25 mg/L) vs. 8.20 mg/L (0.23-34.56 mg/L), with Z values of -3.88 and -5.02, respectively, both P<0.05]. (3) Multivariate logistic regression analysis showed that prolonged duration of PICC placement, decreased platelet count, electrolyte imbalance, metabolic acidosis, and concurrent sepsis were independent risk factors affecting the severity of NEC [ OR (95% CI) values were 1.104 (1.020-1.196), 5.364 (1.667-17.253), 4.047 (1.171-13.986), 4.333 (1.290-14.556), and 3.290 (1.005-10.774), respectively, with all P<0.05]. Conclusions:Prolonged duration of PICC placement, concurrent sepsis, decreased platelet count, electrolyte imbalance, and metabolic acidosis in NEC patients are more likely to lead to severe cases. In clinical practice, attention should be paid to relevant indicators, and abnormal changes should be identified and intervened in a timely manner to reduce the occurrence of severe NEC.

Objective To investigate the current status of pain crisis in patients with advanced colorectal cancer(CRC)and analyze its influencing factors.Methods A total of 186 patients with advanced CRC who were hospitalized in the Oncology Department,the Second Affiliated Hospital of Guizhou University of Traditional Chinese Medicine from June 2024 to March 2025 were selected as the subjects of the investigation.General information questionnaires numerical rating scale,distress tolerance scale,self-rating anxiety scale,self-rating depression scale and quality of life assessment scales were used for the investigation.Logistic regression was used to analyze the influencing factors of pain crisis in patients with advanced CRC.Results Among the 186 CRC patients,87 experienced pain crises,with an incidence rate of 46.8％.The results indicated that pain type,use of analgesics,traditional Chinese medicine adjuvant therapy,metastasis radiotherapy and chemotherapy,pain intensity and pain tolerance were important influencing factors for pain crises in advanced CRC patients.Conclusion The incidence of pain crisis in patients with advanced CRC is relatively high.Nursing staff should promptly identify patients with pain crisis and implement targeted intervention strategies for high-risk patients to reduce the risk of pain crisis.

Objective:To explore the genetic etiology of a child with severe combined immunodeficiency (SCID).Methods:Whole exome sequencing (WES) and copy number variation (CNV) analysis were carried out to screen potential variants in the proband. Suspected variants were validated by Sanger sequencing and qPCR.Results:WES showed that the proband harbored compound heterozygous variants of the DCLRE1C gene, namely deletion of exons 1-3 and c. 322G>A (p.Val108Met) in exon 5. The exon 1-3 deletion was derived from his father and was known to be pathogenic, while the c. 322G>A was derived from his mother and was unreported previously. Conclusion:The compound heterozygous variants of the DCLRE1C gene probably underlay the SCID in this child.

OBJECTIVE: To explore the genetic basis for a child with succinate semialdehyde dehydrogenase deficiency. METHODS: Peripheral blood samples of the proband and his parents were collected and subjected to Sanger sequencing. High-throughput sequencing was used to verify the gene variants. Bioinformatic software was used to analyze the pathogenicity of the variant sites. RESULTS: Sanger sequencing showed that the proband carried a homozygous c.1529C>T (p.S510F) variant of the ALDH5A1 gene, for which his mother was a carrier. The same variant was not detected in his father. However, high-throughput sequencing revealed that the child and his father both had a deletion of ALDH5A1 gene fragment (chr6: 24 403 265-24 566 986). CONCLUSION The c.1529C>T variant of the ALDH5A1 gene and deletion of ALDH5A1 gene fragment probably underlay the disease in the child. High-throughput sequencing can detect site variation as well as deletion of gene fragment, which has enabled genetic diagnosis and counseling for the family.

Objective:To evaluate the therapeutic effect of electroacupuncture on acute gastrointestinal injury (AGI) in patients with severe traumatic brain injury (sTBI).Methods:A prospective randomized controlled trial was conducted. 126 consecutively hospitalized patients with AGI after sTBI admitted to intensive care unit (ICU) of the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from January 2018 to December 2019 were enrolled. The patients were divided into observation group and control group by random number table. All the patients of two groups were given conventional treatment of western medicine for consecutive 7 days, including the treatments of primary diseases, indwelling nasogastric tube to extract gastric contents every 6 hours to determine gastric residual volume (GRV). When vital signs were basically stable, enteral nutrition (EN) was implemented and EN feeding amount and speed were adjusted according to GRV. On the basis of conventional western medicine treatment, the observation group was treated with electroacupuncture at Zusanli, Tianshu, Shangjuxu, Xiajuxu and Zhongwan, once in the morning and once in the evening, 30 minutes each time. The gastrointestinal function parameters including intra-abdominal pressure (IAP), serum diamine oxidase (DAO) and gastrointestinal failure (GIF) scores were observed before treatment and at day 3 and day 7 of treatment. The incidence of ICU hospital-acquired pneumonia (HAP-ICU), duration of mechanical ventilation (MV), length of ICU stay, 28-day mortality and adverse reactions of electroacupuncture were also observed in the two groups. Kaplan-Meier method was used for 28-day survival analysis.Results:During the 7-day treatment and observation, 26 cases of 126 patients withdrew from the study, and 100 cases were actually enrolled, 50 cases in the observation group and 50 cases in the control group. IAP and DAO at day 3 of treatment in both groups were significantly lower than those before treatment [control group: IAP (cmH 2O, 1 cmH 2O = 0.098 kPa) was 13.75±2.76 vs. 18.11±3.97, DAO (U/L) was 129.88±24.81 vs. 158.01±22.64; observation group: IAP (cmH 2O) was 13.56±2.19 vs. 18.50±3.54, DAO (U/L) was 129.11±29.32 vs. 159.36±28.65; all P < 0.01]. The gastrointestinal function parameters of the two groups improved gradually with the extension of treatment time, and the IAP, DAO and GIF scores at day 7 of treatment in the observation group were significantly lower than those in the control group [IAP (cmH 2O): 11.28±3.61 vs. 12.68±3.23, DAO (U/L): 49.69±17.56 vs. 57.27±20.15, GIF score: 2.02±0.74 vs. 2.40±0.70, all P < 0.05). The duration of MV and the length of ICU stay in the observation group were significantly shorter than those in the control group [duration of MV (days): 15.72±4.60 vs. 18.08±4.54, length of ICU stay (days): 16.76±4.68 vs. 19.26±5.42, both P < 0.05], and the incidence of ICU-HAP and 28-day mortality were significantly lowered (12.0% vs. 30.0%, 22.0% vs. 32.0%, both P < 0.05). Survival analysis showed that the 28-day cumulative survival rate in the observation group was significantly higher than that in the control group (86.4% vs. 76.1%; Log-Rank test: χ 2 = 37.954, P < 0.001). The patients in the observation group had no significant adverse reaction of electroacupuncture treatment. Conclusion:Electroacupuncture at corresponding acupoints can effectively improve gastrointestinal function in patients with AGI after sTBI, which is beneficial to shortening the length of ICU stay, promoting the recovery of the patients, and reducing the 28-day mortality.

Objective:To establish and evaluate a follicle isolation method, combination of enzymatically digestion with strainer filtration, for synchronously collecting mouse follicles across different developmental stages.Methods:Pre-cutted ovarian tissue blocks were digested with enzymes mixed by Collagenase I and DNase I, and then filtered through three different pore size cell strainers to synchronously separate the follicles at developmental stages. The follicles obtained by turning over and washing the 100 μm strainer were recorded as group A (>100 μm), as same as the follicles obtained by turning over and washing the 40 μm strainer were recorded as group B (40-100 μm), and the follicles obtained by turning over and washing the 20 μm strainer were recorded as group C (20-40 μm). The quantity, morphology, viability and developmental potency were examined among these harvested follicles.Results:In terms of quantity, follicles in group C accounted for most, followed by follicles in group A, and the follicles in group B were the least. Morphologically, the basal membrane integrity rate of follicles in group C was higher than that of groups B and A ( P<0.001 and P<0.001, respectively). As for viability, the survival rate of follicles in group A was 70.59% (120/170), which was higher than that in group B (51.79%, 58/112) and group C (35.90%, 28/78) ( P=0.001 6 and P<0.001, respectively). In terms of developmental potency, after 96 h of in vitro culture, the diameter of follicles in group A increased from (113.64±9.57) μm to (150.95±45.90) μm ( P=0.002 4), and the diameter of follicles in group B increased from (88.12±9.12) μm to (120.61±18.00) μm ( P<0.001). In group C, monolayer-layer granulosa cells were attached to the follicles within 24 h of culture, and the connection structure between oocytes and granulosa cells was lost. The oocytes were completely exposed and failed to be cultured successfully. Conclusion:Combining enzymatically digestion with multiple strainers filtration is a rapid and effective method for follicle collecting, which is capable to isolate different developmental stage mouse follicles synchronously with morphological integrity, favorable viability and good developmental potency.
