ObjectiveTo explore the effect of Yishen Tongluo prescription on sperm DNA fragmentation index （DFI） and sperm mitochondrial membrane potential （MMP） in patients with asymptomatic idiopathic asthenospermia infertility. MethodsA total of 128 patients with asymptomatic idiopathic asthenospermia were randomly assigned to an experimental group （64 cases） and a control group （64 cases）. The experimental group received Yishen Tongluo prescription， while the control group was treated with Wuzi Yanzongwan combined with L-carnitine oral solution. One treatment course lasted 12 weeks. Spouse pregnancy rate， sperm progressive motility （PR）， total sperm motility （PR+NP）， sperm function （sperm tail hypotonic swelling rate， sperm acrosin activity）， sperm DFI， and sperm MMP were compared between the two groups before and after treatment. Adverse reactions were observed and recorded during the study， and clinical efficacy and safety were systematically evaluated. ResultsA total of 121 patients completed the study， including 61 in the experimental group and 60 in the control group. The spouse pregnancy rate in the experimental group was 14.75% （9/61）， higher than that in the control group at 6.67% （4/60）， though the difference was not statistically significant. Clinical efficacy in the experimental group was superior to that in the control group （P<0.05）. Compared with the results before treatment， sperm PR， PR + NP， sperm tail hypotonic swelling rate， sperm acrosin activity， sperm DFI， and sperm MMP were significantly improved in both groups after treatment （P<0.05）， with greater improvements in the experimental group （P<0.05）. However， there was no significant change in sperm concentration in either group after treatment. During the study， no abnormal safety indicators or significant adverse reactions occurred in either group. ConclusionThe kidney-tonifying and collateral-dredging method shows good clinical efficacy in the treatment of asymptomatic idiopathic asthenospermia infertility. Yishen Tongluo prescription can improve sperm motility， increase spouse pregnancy rate， enhance sperm function， and demonstrates good safety. Its mechanism may be related to reducing sperm DFI and increasing sperm MMP.

Objective : To explore the effect and mechanism of total saponins of astragalus membranaceus combined with bone marrow mesenchymal stem cells (BMSCs) regulating the stromal cell-derived factor-1 (SDF-1) / chemo- kine receptor 4 ( CXCR4) pathway in the treatment of autoimmune premature ovarian failure ( POF) model rats． Methods : Rats were randomly divided into POF group，total saponins of astragalus membranaceus group，BMSCs group ，combination group ，combination + SDF-1 / CXCR4 pathway inhibitor ( AMD3100 ) group ，and control group，with 12 rats in each group．Except for the control group，all other groups of rats needed to construct a POF model．After successful modeling，treatment would begin．The drug injected into the tail vein once a week，and the drug injected into the abdominal cavity once a day for 4 weeks．ELISA was applied to detect the levels of anti ovari- an antibodies (AOAB) ，β-endorphin ( β-EP) ，vascular endothelial growth factor (VEGF) ，tumor necrosis factor- α (TNF-α) ，and interferon-γ ( INF-γ) in serum．Changes in ovarian index were detected．HE staining was ap- plied to detect the number of mature follicles，developing follicles，and blocked follicles in the ovary．Flow cytome- try was applied to detect the proportion of BMSCs in the ovaries．QRT-PCR was applied to detect the mRNA ex- pression of mesenchymal transition factor (cMET) ，hepatocyte growth factor (HGF) ，SDF-1，and CXCR4 in ovar- ian tissue．Western blot was applied to detect SDF-1 and CXCR4 proteins in ovarian tissue． Results : Compared with the control group，the serum levels of AOAB，TNF-α , INF-γ , and the number of blocked follicles in the ova- ries were higher，while the serum levels of β-EP，VEGF，ovarian index，the numbers of mature follicles and devel- oping follicles in the ovary，the expression of SDF-1，CXCR4 mRNA and protein were lower in the POF group (P < 0. 05) ．Compared with the POF group，the serum levels of AOAB，TNF-α , INF-γ , and the number of blocked follicles in the ovaries were lower，while the serum levels of β-EP，VEGF，ovarian index，the numbers of mature follicles and developing follicles in the ovary，the proportion of BMSCs，the expression of cMET ，HGF，SDF-1， CXCR4 mRNA and SDF-1，CXCR4 protein were higher in the total saponins of astragalus membranaceus group， BMSCs group，and combination group，and the corresponding indicators in the combination group showed the most obvious change trend (P＜0. 05) ．AMD3100 reversed the effect of total saponins of astragalus membranaceus com- bined with BMSCs on POF rats． Conclusion The combination of total saponins of astragalus membranaceus and BMSCs may inhibit inflammation in POF rats，promote follicular development，increase the proportion of BMSCs in the ovaries，and promote their homing by activating the SDF-1 / CXCR4 pathway，thereby improving ovarian func- tion．

With the widespread application of diving technology, the safety of long-term diving has become a research focus. Research on the chronic health effects of long-term diving on divers mainly focuses on the respiratory system, circulatory system, nervous system, skeletal system, urinary system, as well as psychological health and sleep. Long-term diving can lead to increased lung capacity, thickening of nasal mucosa, myocardial hypertrophy, changes in heart rhythm, and hearing loss in divers. The impact of long-term diving on health is influenced by diving exposure index such as diving mode, maximum diving depth, underwater stay time, diving frequency, and number of dives, as well as individual factors such as years of diving experience, age, and medical history of divers. However, research on the effects of diving on health are inconsistent, and the potential mechanisms of health damage are unclear. Future large-scale research should be conducted under strict experimental conditions and with standardized inclusion criteria for subjects. Establishing a scientific and systematic assessment method for decompression is crucial for studying the chronic health effects of divers and enhancing understanding of relevant mechanisms to promote the development of diving industry and sport.

Objective To investigate the effect of dynamic lung compliance(Cdyn)-guided indi-vidualized positive end-expiratory pressure(PEEP)on postoperative atelectasis in children undergoing craniofacial reconstruction.Methods Eighty children under general anesthesia undergoing craniofacial re-construction were selected,52 males and 28 females,aged≤1 year,ASA physical status Ⅰ or Ⅱ,anes-thesia duration≥2 hours.According to the random number table method,the children were divided into two groups:Cdyn-guided individualized PEEP group(group Ⅰ)and fixed PEEP group(group P),40 chil-dren in each group.PEEP titration was performed in group Ⅰ after assessing the lung ultrasound(LUS)score 5 minutes after intubation,and the PEEP corresponding to the highest value of Cdyn was an individualized PEEP.In group P,PEEP was fixed 6 cmH2O.The parapleural consolidation score,the B-line score,the total score of LUS,and the incidence of atelectasis were recorded 5 minutes after intubation and at the end of the operation.Cdyn,Ppeak,HR and MAP were recorded 5 minutes after intubation and after PEEP was established.Oxygenation index(OI)was recorded 5 minutes after intubation and at the end of the operation.The incidence of postoperative pulmonary complications within 72 hours after operation were recorded.Results Median individualized PEEP with highest dynamic compliance during titration was 9 cmH2O in group Ⅰ.Compared with 5 minutes after intubation,the total parapleural consolidation score,posterior tho-racic parapleural consolidation score,total B-line score and anterior lateral posterior chest B-line score,and total score of LUS were significantly decreased in both groups at the end of the operation(P＜0.05).Com-pared with group P,the total score of parapleural consolidation,posterior chest parapleural consolidation score,total score of B-line and posterior chest B-line score,and total score of LUS,the incidence of atelec-tasis were significantly decreased in group I at the end of the operation(P＜0.05).Compared with group P,Cdyn and Ppeak in group Ⅰ were significantly increased after PEEP establishment(P＜0.05),OI at the end of the operation was significantly increased(P＜0.05),and the incidence of postoperative pulmonary complications within 72 hours after operation was significantly decreased in group Ⅰ(P＜0.05).Conclusion Intraoperative application of Cdyn-guided individualized PEEP can effectively reduce LUS score and atelectasis at the end of craniofacial reconstruction in children,improve oxygenation function,and reduce the incidence of postoperative pulmonary complications.

Objective:To summarize the genotype and clinical characteristics of chylomicron retention disease (CMRD) caused by secretion associated Ras related GTPase 1B (SAR1B) gene variations.Methods:Clinical data and genetic testing results of 2 children with CMRD treated at Children′s Hospital of Fudan University and Jiangxi Provincial Children′s Hospital from May 2022 to July 2023 were summarized. To provide an overview of the clinical and genetic characteristics of CMRD caused by SAR1B gene variations, all of the literature was searched and reviewed from China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, China VIP database, China Biology Medicine disc and PubMed database (up to January 2024) with "chylomicron retention disease" "Anderson disease" or "Anderson syndrome" as the search terms. All relevant literatures were reviewed to summarize the clinical and genetic features of CMRD caused by SAR1B gene variations.Results:One 11-year-old boy and one 4-month-old girl with CMRD. Both patients had lipid malabsorption, failure to thrive, decreased cholesterol, elevated transaminase and creatine kinase, and Vitamin E deficiency, with homozygous variations (c.224A>G) and compound heterozygous variations (c.224A>G and c.554G>T) in SAR1B gene, respectively. Case 1 was followed up for over a month, and he still occasionally experienced lower limb muscle pain. Case 2 was followed up for more than a year, and her had caught up to normal levels. Both patients had no other significant discomfort. Literature search retrieved 0 Chinese literature and 22 English literatures. In addition to the 2 cases reported in this study, a total of 51 patients were identified as CMRD caused by SAR1B gene variations. Twenty-one types of SAR1B variants 10 missense, 4 nonsense, 3 frameshift, 1 in-frame deletion, 1 splice, 1 gross deletion, and 1 gross insertion-deletion were found among the 51 CMRD cases. Among all the patients, 49 cases had lipid malabsorption (43 cases had diarrhea or fatty diarrhea, 17 cases had vomiting, and 12 cases had abdominal distension), 45 cases had lipid soluble Vitamin deficiency (43 cases had Vitamin E deficiency, 10 cases had Vitamin A deficiency, 9 case had Vitamin D deficiency, and 5 cases had Vitamin K deficiency), 35 cases had failure to thrive, 32 cases had liver involvement (32 cases had elevated transaminases, 5 cases had fatty liver, and 3 cases had hepatomegaly), 29 cases had white small intestinal mucosa under endoscopy, and 17 cases had elevated creatine kinase, 14 cases had neuropathy, 5 cases had ocular lesions, 2 cases had acanthocytosis, 1 case had decreased cardiac ejection fraction, and 1 case was symptom-free.Conclusions:Early infancy failure to thrive and lipid malabsorption are common issues for CMRD patients. The laboratory tests are characterized by hypocholesterolemia with or without fat-soluble Vitamin deficiency, elevated liver enzymes and (or) creatine kinase. Currently, missense variations are frequent among the primarily homozygous SAR1B genotypes that have been described.

Objective:To investigate the genetic, clinical, and post-treatment characteristics of patients with glycogen storage disease type Ⅲ (GSD Ⅲ).Methods:A retrospective cohort analysis was performed on the genetic and clinical data of 26 cases with GSD Ⅲ who visited the Children's Hospital affiliated with Fudan University from June 2017 to December 2023. The patients were divided into non-missense variation and missense variation groups according to the types of mutation in the AGL gene.The correlation between genotype and phenotype was analyzed. All patients were treated with uncooked cornstarch after diagnosis. The changes before and after treatment were compared in patients who underwent more than twelve months of follow-up. A P value of <0.05 was used to denote statistical significance. Results:Among the 26 cases enrolled, 13 were female and 13 were male, and the median age of diagnosis was 28 (6 to 134) months. A total of thirty-five different types of AGL gene variation were detected, with c.1735+1G＞T (9/52, 17.3%) as the hotspot variation. The common clinical manifestations were elevated aminotransferases (26/26, 100%), hepatomegaly (25/26, 96.2%), fasting hypoglycemia (25/26, 96.2%), hyperketonemia (16/18, 88.9%), hypertriglyceridemia (TG) (20/26, 76.9%), elevated CK (16/25, 64.0%), and an abnormal electrocardiogram (12/16, 75.0%). Four cases (15.4%) had symptoms of myopathy at diagnosis. Liver biopsy was performed in eighteen cases, among whom 83.3% (15/18) had liver fibrosis≥S2. The number of cases with elevated levels of CK ( P＝0.031) and ALT ( P＝0.038)was pronounced in the non-missense variation group compared to that in the missense variation group. There were no statistically significant differences in age, height, liver size, degree of fibrosis, fasting blood glucose (Glu) and TG ( P>0.05). The median follow-up time of 14 cases was 40.5 (20-73) months, with improvement in body stature, reduced liver size, decreased ALT and TG, and improved Glu. However, four (28.6%) cases had new myopathy symptoms with raised CK ( P<0.05) and with advancing age, increased ALT diminished while CK level elevated ( P<0.05). Conclusions:The common clinical manifestations at the early stage of the GSD Ⅲdiagnosis are elevated aminotransferases, hepatomegaly, fasting hypoglycemia, hyperketonemia, high triglycerides, elevated CK, and fibrotic liver in China. Myopathy symptoms may arise following uncooked cornstarch treatment; however, there is significant improvement in height, liver-related, and metabolic parameters.

ObjectiveTo observe the clinical efficacy of herb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription in the treatment of infertility induced by idiopathic asthenozoospermia （iAZS） with kidney-Yang deficiency and collateral obstruction syndrome and its effect on sperm DNA damage and superoxide dismutase （SOD） in the seminal plasma. MethodsA total of 112 eligible patients who met the inclusion criteria were randomly divided into an observation group （56 cases） and a control group （56 cases）. The patients in the observation group were treated with herb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription，while those in the control group received levocarnitine oral liquid. The primary observation indicators included spouse pregnancy rate，progressive motility （PR），and total sperm motility，and the secondary observation indicators included sperm DNA fragmentation index （DFI），SOD in the seminal plasma， and improvement of TCM syndromes. The treatment cycle was 12 weeks. Before and after treatment，the PR，total sperm motility，sperm DFI，SOD in the seminal plasma， and TCM syndrome scores were recorded. The patients were followed up for 12 weeks and the pregnancy status of spouses within 24 weeks （half a year） was recorded. The clinical efficacy of the two groups was evaluated. ResultThe pregnancy rate of spouses in the observation group was 15.69% （8/51）， higher than 3.85% （2/52） in the control group （χ²=4.118，P<0.05）. The total effective rate of the observation group was 88.24%（45/51）， superior to 69.23% （36/52）in the control group （Z=-3.402，P<0.01）. After treatment， PR， total sperm motility，sperm DFI， SOD in the seminal plasma， and TCM syndromes of the two groups were improved compared with those before treatment （P<0.05）， and the observation group was superior to the control group （P<0.05）. ConclusionHerb-partitioned moxibustion on the navel combined with Yishen Tongluo prescription in the treatment of iAZS-induced infertility patients with kidney-Yang deficiency and collateral obstruction syndrome can increase PR，total sperm motility， and SOD level in the seminal plasma， reduce sperm DFI，improve the TCM symptoms of patients， and improve the pregnancy rate of spouses. The mechanism may be attributed to the fact that this treatment can increase the SOD level in the seminal plasma of patients，enhance the body's antioxidant function，protect sperm from oxidative stress damage，and reduce sperm DFI.

【Objective】 To explore the effect of lactate and alkali deficiency on the need for red blood cell transfusion in emergency of patients with traumatic hemorrhagic shock. 【Methods】 A total of 126 patients with traumatic hemorrhagic shock in our hospital from January 2019 to December 2021 were retrospectively analyzed, and the 99 cases with effective treatment were divided into two groups according to the outcome of blood transfusion within 24 hours after admission: non-transfusion group (n=36) and transfusion group (n=63). The changes of lactic acid (Lac), alkali deficiency (BE), hemoglobin (Hb), hematocrit (Hct) at admission, hemoglobin (Hb), hematocrit (Hct) 24 hours after admission and the length of stay in ICU were compared between the two groups. The binary logistic regression was used to analyze the risk factors of whether there was a need for blood transfusion at the time of emergency admission. The correlation between individual and combined indicators of each risk factor and the need for blood transfusion were analyzed by the receiver operating curve (ROC). 【Results】 The mean level of Lac (2.90±1.82) in the non-transfusion group at admission was lower than that in the transfusion group (5.80±2.83) (P<0.05), while BE、Hb and Hct (-1.76±3.24, 120.78±20.83, 35.76±6.11) were higher than those in the transfusion group (-5.91±4.69, 101.32±29.68, 29.97±8.48) (P<0.05). The mean levels of Hb and Hct in the two groups 24 hours after admission (92.75±16.66, 78.49±15.91) and (27.62±5.24, 22.60±4.74) were lower than those at admission (P<0.05). Binary logistic statistical analysis confirmed that Lac (OR=1.74, 95% CI 1.493-2.927, P<0.01), BE (OR=0.77, 95% CI 0.676-0.883, P<0.01), Hb (OR=0.97, 95% CI 0.954-0.989, P<0.01), Hct (OR=0.90, 95% CI 0.844=0.96, P<0.01) had guiding significance for patients with traumatic hemorrhagic shock to have red blood cell transfusion demand, and the increase of blood lactic acid was an independent risk factor (P<0.05), while age and gender had no significant effect on it(P>0.05)The maximum AUG of Lac and BE(0.875, 0.766) in predicting the need for emergency red blood cell transfusion in patients with traumatic hemorrhagic shock was significantly better than that of Hb and Hct (0.692, 0.682); the optimal threshold for Lac was >3.6 mmol/L, while the optimal threshold for Hb is ≤106 g/L; the maximum AUG obtained by ROC curve analysis combined with Lac, BE, Hb and Hct was 0.910, which was higher than that of the sole virable. Comparative predictive value using the optimal thresholds of Lac and Hb as indications for transfusion showed that Lac had better predictive value than Hb. 【Conclusion】 Lac and be can be instructive for patients with traumatic hemorrhagic shock as to whether they need red blood cell transfusion in an emergency setting, and combination of Lac, BE, Hb and Hct may help to determine the transfusion needs of patients more timely and accurately and optimize the transfusion management of emergency patients.

Objective:To evaluate the effect of Mongolian medicine Eerdun Wurile on postoperative cognitive function in elderly patients undergoing thoracoscopic lobectomy.Methods:Sixty elderly patients of either gender, aged ≥60 yr, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, with body mass index≤28 kg/m 2, with preoperative Mini-Mental State Examination (MMSE) score ≥27 points, undergoing thoracoscopic lobectomy under general anesthesia, were divided into 2 groups ( n=30 each) using the random number table method: control group (group C) and Eerdun Wurile group (group E). Eerdun Wurile 15 capsules per day were taken for 7 consecutive days starting from 3 days before surgery in group E, and placebo was given instead in group C. The peripheral venous blood samples were collected before medication at 3 days before surgery (T 1) and 24 and 72 h after surgery (T 2, 3) for determination of the concentrations of serum brain-derived neurotrophic factor (BDNF), interleukin-1beta (IL-1β), tumor necrosis factor-alpha (TNF-α) and Tau proteins by enzyme-linked immunosorbent assay. The patients′ cognitive function was assessed by MMSE at T 1 and 5 days after surgery (T 4), and the occurrence of cognitive decline (MMSE score < 27) was recorded. Results:Compared with group C, the serum BDNF concentration was significantly increased at T 2 and T 3, and the concentrations of IL-1β, TNF-α and Tau protein were decreased, the MMSE score was increased at T 4, and the incidence of cognitive decline was decreased in group E ( P<0.05). Conclusions:Mongolian medicine Eerdun Wurile can improve postoperative cognitive function in elderly patients undergoing thoracoscopic surgery, and the mechanism may be related to reduction of systemic inflammatory responses and promotion of nerve cell repair and regeneration.

Background:In the clinical setting, the effect of intra-abdominal hypertension on the human body is dependent on time, but its role is not yet clear.Objective:To investigate the effect of the duration of intra-abdominal hypertension (IAH) on the prognosis of critically ill patients.Methods:This prospective cohort study enrolled 256 IAH patients who were admitted to the Surgical ICU of 10 Grade A hospitals in Fujian Province from January 2018 to December 2020. The duration of IAH (DIAH) was obtained after monitoring IAP, and ICU length of stay, duration of mechanical ventilation, duration of continuous renal replacement therapy (CRRT) and average daily energy intake from enteral nutrition during ICU stay were observed and recorded. The correlation was analyzed by Spearman rank correlation. The patients were divided into the survival group and the death group according to their survival state at 60 days after enrollment. Thereafter, clinical characteristics between the two groups were compared. Multivariable logistic regression was used to study and validate the relationship between DIAH and 60-day mortality. The receiver operating characteristics (ROC) curve was established to evaluate the predictive abilities of DIAH on the mortality risk.Results:In critically ill patients, DIAH was positively correlated with duration of mechanical ventilation ( r=0.679, P<0.001), duration of CRRT ( r=0.541, P<0.001) and ICU length of stay ( r=0.794, P<0.001), respectively. In addition, there was a negative correlation between DIAH and average daily energy intake from enteral nutrition ( r=-0.669, P<0.001). After multivariable adjustment, DIAH was an independent risk factor for 60-day mortality in critically patients with IAH ( OR=1.05, 95% CI: 1.01-1.12; P = 0.012), and exhibited a linearity change trend relationship with mortality risk. The ROC curve analysis of DIAH showed that the area under ROC curve (AUC) was 0.825 (95% CI: 0.763~0.886, P<0.01). When the cut-off value was 16.5 days, the sensitivity was 78.4% and the specificity was 75.4%. Conclusions:DIAH is an important risk factor for prognosis in critically ill patients. Early identification and rapid intervention for the etiology of IAH should be performed to shorten DIAH.
