Objective To observe the clinical efficacy of fire needling in treating lumbar disc herniation(LDH)of cold-damp type under the guidance of meridian sinew theory.Methods A total of 70 cases of patients with LDH of cold-damp type were randomly divided into observation group and control group,35 cases in each group,the control group was given conventional acupuncture treatment,and the observation group was treated with fire needling under the guidance of meridian sinew theory on the basis of the treatment of the control group,and the course of treatment covered three courses,one week as a course.After three courses of treatment,the clinical efficacy of the two groups was evaluated,and the changes in the Visual Analogue Scale(VAS)scores of pain,the Japanese Orthopedic Association(JOA)scores,and traditional Chinese medicine(TCM)syndrome scores of patients in the two groups before and after treatment were observed.Results(1)During the study,there were three cases in the observation group and five cases in the control group were failed to follow-up.Finally,32 cases in the observation group and 30 cases in the control group were included in the efficacy statistics.(2)The total effective rate was 93.75%(30/32)in the observation group and 86.67%(26/30)in the control group.The clinical efficacy of the observation group was superior to that of the control group,and the difference being statistically significant(P<0.05).(3)After treatment,the VAS and JOA scores of patients in the two groups improved significantly(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(4)After treatment,the TCM scores of the two groups of patients improved significantly(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).Conclusion Under the guidance of the meridian sinew theory,fire needling in treating LDH of cold-damp type can significantly reduce the degree of pain,improve the lumbar function,alleviate LDH-related symptoms,so as to improve the patients'quality of life.

Objective:To investigate the impact of early invasive arterial blood pressure (IBP) monitoring on survival and neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR).Methods:This retrospective cohort study analyzed 44 OHCA patients receiving ECPR between January 2021 and January 2023. Patients were divided into: Early intervention group : IBP established within 3 min of ECMO initiation; Late intervention group : IBP established after ICU admission. Baseline characteristics, ECMO parameters, and clinical outcomes were compared. Multivariable logistic regression (adjusted for age, initial rhythm, etc.) and Spearman's correlation were used.Results:This study included a total of 44 patients treated with OHCA and ECPR, divided into an early intervention group of 23 cases and a late intervention group of 21 cases. The early intervention group showed significantly higher: Survival to discharge (43.5% vs. 9.5%, P<0.05), Good neurological recovery (CPC 1-2: 34.8% vs. 9.5%, P<0.05).Early intervention independently predicted survival (adjusted OR=18.84, 95% CI:1.97-179.98, P=0.01). Stratified analysis by pH (cutoff 7.0) demonstrated consistent benefits in both pH>7.0 ( aOR=0.392, 95% CI:0.106-0.678) and pH≤7.0 subgroups ( aOR=0.385, 95% CI: 0.075-0.695; interaction P=0.183). Early IBP positively correlated with CPC scores ( ρ=0.40, P=0.007). Conclusions:Early IBP monitoring significantly improves survival and neurological outcomes in OHCA-ECPR patients, supporting its integration into standardized protocols.

Background::Hypothermia therapy has been suggested to attenuate myocardial necrosis; however, the clinical implementation as a valid therapeutic strategy has failed, and new approaches are needed to translate into clinical applications. This study aimed to assess the feasibility, safety, and efficacy of a novel selective intracoronary hypothermia (SICH) device in mitigating myocardial reperfusion injury.Methods::This study comprised two phases. The first phase of the SICH was performed in a normal porcine model for 30 minutes ( n = 5) to evaluate its feasibility. The second phase was conducted in a porcine myocardial infarction (MI) model of myocardial ischemia/reperfusion which was performed by balloon occlusion of the left anterior descending coronary artery for 60 minutes and maintained for 42 days. Pigs in the hypothermia group ( n = 8) received hypothermia intervention onset reperfusion for 30 minutes and controls ( n = 8) received no intervention. All animals were followed for 42 days. Cardiac magnetic resonance analysis (five and 42 days post-MI) and a series of biomarkers/histological studies were performed. Results::The average time to lower temperatures to a steady state was 4.8 ± 0.8 s. SICH had no impact on blood pressure or heart rate and was safely performed without complications by using a 3.9 F catheter. Interleukin-6 (IL-6), tumor necrosis factor-α, C-reactive protein (CRP), and brain natriuretic peptide (BNP) were lower at 60 min post perfusion in pigs that underwent SICH as compared with the control group. On day 5 post MI/R, edema, intramyocardial hemorrhage, and microvascular obstruction were reduced in the hypothermia group. On day 42 post MI/R, the infarct size, IL-6, CRP, BNP, and matrix metalloproteinase-9 were reduced, and the ejection fraction was improved in pigs that underwent SICH.Conclusions::The SICH device safely and effectively reduced the infarct size and improved heart function in a pig model of MI/R. These beneficial effects indicate the clinical potential of SICH for treatment of myocardial reperfusion injury.

Objective:To investigate the clinical characteristics and management status of children with Turner syndrome (TS) in China.Methods:As a cross-sectional study, 1 089 TS patients were included in the database of the National Collaborative Alliance for the Diagnosis and Treatment of Turner Syndrome from August 2019 to November 2023. Clinical characteristics (growth development, sexual development, organ anomalies, etc.), karyotypes, auxiliary examinations, and treatments were collected and analyzed.Results:Among the 1 089 TS cases, 809 were recorded karyotypes. The karyotype distribution was as follows: 45, X in 317 cases (39.2%), X chromosome structural variants (including partial deletions of p or q arm, ring chromosome, and marker chromosome) in 89 cases (11.0%), 45, X/46, XX mosaicism in 158 cases (19.5%), mosaicism with X chromosome structural variants in 209 cases (25.8%), and presence of Y chromosome material in 36 cases (4.4%). Among the 824 TS cases, the age of diagnosis was 9.7(6.4, 12.2) years, with a height standard deviation score (HtSDS) of -3.1±1.2. Five hundred and fifty three cases underwent growth hormone (GH) stimulation test, and 352 cases (63.7%) had GH peak values <10 μg/L and 75.9% (577/760) had low IGF1 levels, with IGF1 SDS ≤-2 accounting for 38.2% (290 cases). Among 471 cases aged ≥8 years, 132 cases (28.0%) showed spontaneous sexual development (mean bone age (11.0±1.7) years), 10 cases had spontaneous menarche (mean bone age (12.0±2.2) years), and 2 cases had regular menstrual cycles. Common physical features included cubitus valgus (311 cases (28.5%)), neck webbing (188 cases (17.2%)), low posterior hairline (185 cases (17.0%)), shield chest (153 cases (14.0%)), high arched palate (127 cases (11.6%)), short fourth metacarpal (43 cases (3.9%)), and spinal abnormalities (38 cases (3.5%)). Congenital cardiovascular and urogenital anomalies occurred in 91 cases (19.4%) and 66 cases (12.0%)respectively. Abdominal ultrasound in 33 cases (7.2%) indicated fatty liver, hepatomegaly, intrahepatic bile duct stones, and splenomegaly. Among 23 cases undergoing oral glucose tolerance test (OGTT) test, 2 were diagnosed with diabetes mellitus and 4 with impaired glucose tolerance. Following diagnosis, 669 cases (80.7%) received rhGH treatment at a chronological age of (9±4) years and bone age of (8.3±3.2) years. Additionally, 112 cases (19.4%) received sex hormone replacement therapy starting at the age of (14±4) years and bone age of (12.6±1.2) years.Conclusions:The karyotypes of 45, X and mosaicism were most common in Chinese children with TS. The clinical manifestations were mainly short stature and gonadal dysplasia. However, a few TS children could be in the normal range of height, and some cases among those aged of ≥8 years old had spontaneous sexual development. Some exhibited physical features, congenital cardiovascular and urogenital anomalies, and dysfunction of the hypothalamic-pituitary-IGF1 axis. Moreover, a few of them developed impaired glucose tolerance and diabetes mellitus. Following diagnosis, most of the patients received rhGH treatment, and a few of them received sex hormone replacement therapy.

[Objective] To evaluate the effects of preoperative ureteroscopy (URS) on the prognosis of patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). [Methods] Data of 712 UTUC patients who received RNU in West China Hospital during May 2003 and Jun.2019 were retrospectively analyzed. Patients were divided into URS group (n=187) and non-URS group (n=525) according to whether URS was performed before RNU. Kaplan-Meier curves were used to analyze the overall survival (OS), cancer-specific survival (CSS), and intravesical recurrence-free survival (IVRFS). Cox proportional risk model was used for risk assessment. Subgroup analysis and interaction test were used to further verify the results. [Results] Significant differences were observed between the two groups in terms of body mass index (BMI), diabetes mellitus, surgical method, hydronephrosis, tumor location, tumor grade, lymph node metastasis, lymphovascular invasion and tumor diameter (P<0.05). Kaplan-Meier survival analysis showed that IVRFS was significantly lower in the URS group than in the non-URS group (P<0.001), and the difference was more pronounced in renal pelvis carcinoma (P<0.001); there were no differences in OS and CSS between the two groups (P>0.05). Cox multivariate regression showed that URS was an independent risk factor for intravesical recurrence (HR=2.12, 95%CI: 1.34-3.36, P<0.001). [Conclusion] Preoperative URS can increase the recurrence rate of UTUC, but it has no effect on the OS and CSS.

Glycolytic metabolism enzymes have been implicated in the immunometabolism field through changes in metabolic status. PGK1 is a catalytic enzyme in the glycolytic pathway. Here, we set up a high-throughput screen platform to identify PGK1 inhibitors. DC-PGKI is an ATP-competitive inhibitor of PGK1 with an affinity of K _d = 99.08 nmol/L. DC-PGKI stabilizes PGK1 in vitro and in vivo, and suppresses both glycolytic activity and the kinase function of PGK1. In addition, DC-PGKI unveils that PGK1 regulates production of IL-1β and IL-6 in LPS-stimulated macrophages. Mechanistically, inhibition of PGK1 with DC-PGKI results in NRF2 (nuclear factor-erythroid factor 2-related factor 2, NFE2L2) accumulation, then NRF2 translocates to the nucleus and binds to the proximity region of Il-1β and Il-6 genes, and inhibits LPS-induced expression of these genes. DC-PGKI ameliorates colitis in the dextran sulfate sodium (DSS)-induced colitis mouse model. These data support PGK1 as a regulator of macrophages and suggest potential utility of PGK1 inhibitors in the treatment of inflammatory bowel disease.

Objective:To investigate the changes of T lymphocyte subsets and cytokines in children with he-patitis B virus(HBV)-associated glomerulonephritis (HBV-GN), and their relationship with HBV-DNA load.Methods:Forty-one children who was the first diagnosed with HBV-GN in Department of Pediatrics, the People′s Hospital of Gansu Province and Institute of Infectious Diseases, the First Hospital of Lanzhou University from September 2012 to September 2016 were collected as the objects(HBV-GN group). At the same time, the 40 patients with HBV infection (chronic HBV infection, normal liver and kidney function, normal 24-hour proteinuria quantitation, no hematuria under the microscope, no recent symptoms of cold and fever, etc.) were enrolled as the control group.The levels of T lymphocyte subset, tumor necrosis factor α(TNF-α), interferon-γ (IFN-γ), interleukin (IL)-2, IL-4, IL-6, IL-8 and IL-10 in the HBV-GN group and the control group were compared, and the relationship between HBV-DNA and cell factors was farther analyzed.Results:Compared with the control group, the proportions of CD3 + T, CD4 + T lymphocyte and CD4 + /CD8 + ratio decreased in the HBV-GN group(0.632±0.052 vs.0.692±0.047, 0.204±0.050 vs.0.466±0.038, 0.006±0.002 vs.0.017±0.003, t=1.025, 3.342, 5.234, all P<0.05), and the proportions of CD8 + T lymphocyte was significantly higher than that in the control group (0.411±0.023 vs.0.220±0.043, t=4.452, P<0.01). Besides, IL-2 and IFN-γ levels in the HBV-GN group were significantly lower than those in the control group[(23.36±2.55) ng/L vs.(36.33±1.24) ng/L, (19.20±2.18) ng/L vs.(61.25±2.08) ng/L, all P<0.05], and the serum levels of TNF-α, IL-4, IL-6, IL-8, and IL-10 were significantly higher than those in the control group[(19.60±1.46) ng/L vs.( 6.68±2.32) ng/L, (13.65±3.34) ng/L vs.(1.35±1.52) ng/L, (5.57±1.02) ng/L vs.(1.43±0.57) ng/L, (26.32±3.45) ng/L vs.(9.68±2.55) ng/L, (19.82±2.78) ng/L vs.(1.02±0.56) ng/L, all P<0.01]. Moreover, in HBV-GN patients, there was negative correlation between HBV-DNA load and IFN-γ, IL-2( r=-0.985, -0.943, all P<0.05), and positive relationship in HBV-DNA load with TNF-α, IL-4, IL-6, IL-8 and IL -10 levels( r=0.942, 0.966, 0.953, 0.944, 0.963, all P<0.05). Conclusions:There is an CD4 + /CD8 + imbalance and an abnormal level of cell factors in HBV-GN progression.In further HBV-GN treatment, HBV-DNA and the cell factors should be detected simultaneously to dynamically eva-luate the illness change and the clinical curative effect.

Thirty-six puerperas who underwent emergency cesarean section at Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology from January 24, 2020 to February 9, 2020, who all wore medical surgical masks, were retrospectively included in this study.Anesthesia management was performed under tertiary medical protection measures.A dedicated anesthesia equipment was separately sterilized.Narcotic drugs were used for one patient only, and disposable medical supplies were used for anesthetic supplies.Contact transmission should be avoided when a neonate required resuscitation, and early isolation and nucleic acid testing were provided for the neonates.The rate of suspected cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was 11% , and the rate of clinically diagnosed cases was 17% before surgery.The rate of clinically diagnosed cases of SARS-CoV-2 was 22%, the rate of confirmed cases was 8%, and the total positive rate of diagnosis was 31% after surgery.The rate of neuraxial anesthesia was 86%, the rate of general anesthesia was 14%, the time of spinal puncture was (15±7) min, the time of tracheal intubation under general anesthesia was (2.1±1.3) min, the operation time was (95±36) min, and blood loss was (276±166) ml.The Apgar score of newborns was 8.8±0.5.There was 1 neonate whose mother was diagnosed as having coronavirus disease 2019 after operation, an oropharyngeal swab specimen was obtained at 36 h of birth, and the swab was tested positive for SARS-CoV-2 by nucleic acid testing.As of February 10, 2020, an anesthesiologist involved in the operation was diagnosed to have infection by SARS-CoV-2.In conclusion, diagnosis of coronavirus disease 2019 during pregnancy is more difficult, it is necessary to perform anesthesia management for cesarean section under tertiary medical protection.Although the difficulty in anesthesia operation is increased under tertiary medical protection, anesthesiologists can carry out standardized anesthesia management and guarantee the safety of maternal and infants and anesthesiologists themselves as long as they are rigorously trained and adhere to protective protocols.

Objective:To study the clinical characteristics and gene mutations in a family with combined inherited antithrombin (AT) and factor Ⅶ (FⅦ) deficiency, and explore the relationship between AT gene, F7 gene mutations and diseases. Methods:Pedigree investigation. Blood samplesand clinical dataswere collected fromthe proband and her family members (a total of 16 people in 3 generations) who admitted to the First Affiliated Hospital of Wenzhou Medical University in November 2018. The prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), antithrombin activity (AT: A), antithrombin antigen (AT: Ag), protein C activity (PC: A), protein S activity (PS: A), FⅦ activity (FⅦ: C), FⅦ antigen (FⅦ: Ag) and other indicators were detectedto confirm the diagnosis. DNA direct sequencing analysis of all exons, flanking sequences, 5′ and 3′ untranslated regions of AT genes and F7 genes, and the mutation sites were confirmed by clone sequencingor reverse sequencing. Results:The AT: A and AT: Ag of the proband were 46% and 135 mg/L, respectively (reference range: 250-360 mg/L), some of her family members′ s (father, aunt, two cousins, younger brother and nephew) AT: A and AT: Ag were reduced to 50% of normal range. Her father (Ⅰ 2), aunt (Ⅰ 4), elder brother (Ⅱ 7), younger brother (Ⅱ 8), and nephew (Ⅲ 3)′s FⅦ: C were 45%, 50%, 48%, 47% and 48%, respectively; and their FⅦ:Ag was within the normal range. Genetic analysis revealed that the proband(Ⅱ 6) and some of her family members (father, aunt, two cousins, younger brother and nephew) took rs3138521 polymorphism in the 5′ untranslated region of AT gene. Her father (Ⅰ 2), aunt (Ⅰ 4), elder brother (Ⅱ 7), younger brother (Ⅱ 8), nephew (Ⅲ 3) took c.1091G>A heterozygous missense mutationin exon 8 of F7 gene, resulting in p.Arg304Gln. Conclusion:The rs3138521 in AT gene and c.1091G>A in F7 gene, which may be the molecular mechanism leading to combined inherited AT and FⅦ deficiency in this family.

Objective To understand the epidemiological characteristics of the novel coronavirus diseases 2019 (COVID-19), and to scientifically guide the prevention and control of COVID-19 in Hubei Province. Methods All COVID-19 cases reported online in Hubei Province as of March 31, 2020 were extracted from Hubei^'s Infectious Disease Information System. The epidemic curve, age and sex characteristics, and spatiotemporal distribution characteristics of the COVID-19 cases were analyzed. Results As of March 31, 2020, a total of 70 764 cases were reported in Hubei Province, including 49 195 confirmed cases. A total of 4 579 deaths occurred among the confirmed cases, and the reported case fatality rate was 6.47%. The peak of the onset of symptoms occurred from January 20 to February 14, 2020. The sex ratio of male to female of the confirmed cases was 0.99: 1, and most were 30-69 years old. The cases diagnosed before January 5 were mainly reported by Wuhan City. From January 6 to January 31, all counties and districts in the province reported that the incidence of confirmed COVID-19 cases began to rise, and about 50% counties reported that the morbidity rate of confirmed COVID-19 cases was over 10 cases per 100 000. The morbidity rate of COVID-19 cases rose rapidly between February 1-15, and then gradually reached its peak after February 16. Conclusion Wuhan City of Hubei Province first discovered and reported the COVID-19 outbreak. The onset of symptoms peaked in January 20 to February 14, and the 30-69 years old group was the key population. Many measures such as restricting personnel movement, reducing contact, and strengthening health education played an important role in controlling the outbreak of COVID-19 in Hubei.
