Objective To study the development of conus medullaris by quantitative three-dimensional ultrasound in the second and third trimesters of pregnancy,and to analyze the value of terminal caudal vertebral ossification center count in diagnosis of closed spina bifida.Methods A total of 108 normal fetuses in the second and third trimesters of pregnancy who were admitted to Baoding No.1 Central Hospital from January 2019 to March 2024 were selected and assigned to the normal group.The distance between the fetal conus medullaris and the first sacral vertebra,the distance between the end of the conus medullaris and the end of sacrum,and the number of corresponding vertebrae were measured by three-dimensional ultrasound at different gestational weeks.Meanwhile,54 fetuses who were confirmed to have closed spina bifida after delivery were enrolled into the abnormal group.The number of ossification centers on the median sagittal section of the caudal spine was counted and compared between the two groups.The receiver operating characteristic(ROC)curve was drawn to analyze the value of ossification center count of distal caudal vertebrae in diagnosis of closed spina bifida.Results With the increase of gestational weeks,the distance between the fetal conus medullaris and the first sacral vertebra and the distance between the end of the conus medullaris and the end of the sacral bone were gradually increased.The conus medullaris of normal fetuses was mainly located in L1.5,L2 and L2.5,accounting for 85.19%(92/108).The ossification center count of distal caudal vertebra was slightly increased with the increase of gestational weeks in the normal group.At 17-20 gestational weeks,85.71%(12/14)of the ossification center count of distal caudal vertebra was 5 to 7.At 21-28 gestational weeks,100.00%(45/45)of the ossification center count was 6 and more.At week 29 and above,100.00%(45/45)of the ossification center count was more than 7.In the abnormal group,96.30%(52/54)of the fetuses had the ossification center less than 6,and 85.71%(42/49)of the ossification center count was≤5 at 21-32 gestational weeks.There were significant differences in the ossification center count between the two groups at 17-20,21-24,25-28,29-32,and 33-36 gestational weeks(P<0.05).ROC curve showed that,at 17-20,21-24,25-28,29-32,and 33-36 gestational weeks,the area under the curve(AUC)in prediction of closed spina bifida was 0.804,0.744,0.776,0.819,and 0.722 when the ossification center count of distal caudal vertebra was 5.31,4.59,4.81,4.67,and 5.49 as the cut-off value,respectively.Conclusion The conus medullaris moves upward with the increase of gestational weeks in the second and third trimesters of pregnancy.The ossification center count of the distal caudal vertebra is less than 6 in most fetuses with closed spina bifida,which is conducive to screening for closed spina bifida.

Objective To investigate the current status of semen testing in the hospitals without assisted reproductive technology in Hu-nan Province,propose improvement strategies to enhance the diagnosis of male infertility and promote reproductive health services in these hospitals.Methods Questionnaire surveys and on-site investigations were conducted to examine the semen testing status in 67 hospitals without assisted reproductive technology in Hunan Province.The existing problems were summarized,and improvement strate-gies were suggested.Results Among the 67 hospitals,59.7％(40/67)performed semen testing.Of these,45％(18/40)possessed dedicated personnel,60％(24/40)possessed staff received relevant training,and 22.5％(9/40)held certificates.Only 30％(12/40)conducted sperm morphology testing,among them 20％(8/40)able to stain and interpret following WHO standards.The hospitals of 37.5％(15/40)used computer-assisted sperm analysis(CASA)systems,and 22.5％(9/40)were equipped with phase-contrast microscopes.30％(12/40)had dedicated examination areas,and 32.5％(13/40)had independent ejaculation rooms,17.5％(7/40)used disposable slides to observe sperm concentration.In 2022,the hospitals of 57.5％(23/40)had an average daily sample volume＜1.The hospital of 67.5％(27/40)performed standard operating procedures,40％(16/40)followed the WHO 5th la-boratory manual for routine testing,15％(6/40)conducted internal quality control,and 12.5％(5/40)participated in external quali-ty assessment(EQA).Another 55％(22/40)wished to participate in EQA.Conclusion The semen testing capacity in the hospitals,in which assisted reproductive technology is not yet carried out currently,urgently requiring multifaceted improvements.The proposed strategies include emphasizing semen testing,establishing reproductive medicine consortia for comprehensive support,establishing a provincial quality control center for EQA,founding a professional committee for a learning platform,offering training to enhance staff expertise,and including the pre-pregnancy semen testing in public health programs.

AIM: To compare the outcome of C3F8 versus silicone oil tamponade after pars plana vitrectomy(PPV)and inverted internal limiting membrane(ILM)for the treatment of highly myopic macular hole retinal detachment(MHRD).METHODS: Retrospective clinical study. Totally 45 patients(45 eyes)with highly myopic MHRD who visited our hospital between January 2019 and August 2022 were selected as the research subjects. The patients were divided into two groups according to different intraocular tamponade agents: C3F8(22 eyes)and silicone oil(23 eyes)groups. All patients underwent conventional three-incision PPV, ILM was tamped, a venous blood clot was placed on the tamped ILM, and 15% C3F8 and silicone oil were used as tamponade, respectively. The best corrected visual acuity(BCVA), multifocal electroretinogram(mfERG), the closure of the macular hole, retinal reattachment and the complications were observed.RESULTS: The macular hole closure rate was 77% in the C3F8 group and 83% in the silicone oil group, respectively(P>0.05), and retinal reattachment rates were 95% and 96%, respectively(P>0.05). The visual acuity of the two groups significantly improved, which was 0.99±0.34 and 1.22±0.37, respectively, and the C3F8 group was better than that of the silicone oil group(t=-2.156, P=0.037). After operation, the response density of the first ring of P1 wave in the first order kernel in mfERG was 114.27±26.37 nV/deg2 for the C3F8 group and 98.08±24.36 nV/deg2 for the silicone oil group, and the response density of the second ring of P1 wave was 80.45±14.94 nV/deg2 for the C3F8 group and 67.73±15.33 nV/deg2 for the silicone oil group, all of which were significantly higher compared to pre-operation [the response density of the first ring of P1 wave: 58.13±13.96 nV/deg2 for the C3F8 group and 55.30±10.48 nV/deg2 for the silicone oil group, the response density of the second ring of P1 wave: 51.18±8.19 nV/deg2 for the C3F8 group and 47.43±11.97 nV/deg2 for the silicone oil group](all P<0.05). It was found that the response density of the first ring of P1 wave was lower in the silicone oil group than in the C3F8 group(P<0.05). There was no statistically significant difference in the incidence of complications between the two groups(P>0.05).CONCLUSION: Silicone oil tamponade or C3F8 tamponade after PPV combined with ILM can both promote retinal reattachment and macular hole closure in patients with MHRD, and the C3F8 tamponade was superior to silicone oil in visual function recovery.

Objective To study the levels of serum Periostin and interleukin(I1-)-18 in preterm infants with bronchopulmonary dysplasia(BPD),and to analyze their correlation with the severity of the disease and their predictive value for BPD.Methods A total of 62 preterm infants with BPD diagnosed and treated in the hospital from January 2019 to January 2022 were retrospectively selected as the BPD group,and 80 preterm in-fants without BPD during the same period were selected as the non-BPD group.According to the severity of BPD,the infants with BPD were divided into mild subgroup(22 cases),moderate subgroup(24 cases)and se-vere subgroup(16 cases).The serum levels of Periostin and IL-18 were detected by enzyme-linked immu-nosorbent assay.Pearson correlation analysis was used to analyze the correlation between the clinical parameters.Multivariate Logistic regression was used to analyze the influencing factors of BPD,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of each indicator for BPD.Results Compared with the non-BPD group,the BPD group had a significantly higher proportion of infants with pulmonary surfactant(PS)use,neonatal respiratory distress syndrome,apnea,patent ductus arteriosus,and serum levels of Periostin and IL-18,as well as a significantly longer duration of mechanical ventilation,noninvasive respiratory support,and length of hospital stay.The lung function parameters[tidal volume per kilogram(VT/kg),ratio of time to peak tidal expiratory flow to time(TPTEF/TE),ratio of volume to peak tidal expiratory flow to volume(VPEF/VE),expiratory flow at 50％tidal volume(50％TEF),expiratory flow at 75％tidal volume(75％TEF)]and 1,5 min Apgar score of BPD group were lower than that of non-BPD group,and the differences were statistically significant(P＜0.05).The serum levels of Periostin and IL-18 in mild subgroup,moderate subgroup and severe subgroup were increased in turn.The levels of serum Periostin and IL-18 were negatively correlated with pulmonary function indexes(VT/kg,50％TEF,75％TEF,TPTEF/TE,VPEF/VE,P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for BPD(P＜0.05),and PS was a protective factor(P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for the severity of BPD(P＜0.05).The area under the curve(95％CI)of serum Periostin and IL-18 alone and in combination for predicting BPD were 0.841(0.814-0.899),0.863(0.820-0.897),0.922(0.878-0.949),respectively.The sensitivity and specificity of combined prediction were 0.902 and 0.825,respectively.The area under the curve of the combination of the two indica-tors for predicting BPD was greater than that of each index alone,and the difference was statistically signifi-cant(Z=5.357,4.894,P＜0.001).Conclusion The levels of serum Periostin and IL-18 are increased in in-fants with BPD,which are related to the severity of BPD and lung function.The combination of serum Perios-tin and IL-18 has a high predictive value for BPD.

Objective To investigate the analgesic effect of multi-site multiple paravertebral nerve blocks on patients undergoing radical lung cancer surgery and the impact on their serum indices and prognosis.Methods Ninety-eight cases of patients undergoing thoracoscopic radical lung cancer surgery in our hospital were selected from March 2021 to January 2023 and divided into 2 groups according to the difference in anaesthesia.Among them,42 patients in the study group were treated with preoperative and postoperative multipoint paravertebral nerve block combined with general anaesthesia,while 56 patients in the control group were treated with preoperative multipoint paravertebral nerve block combined with general anaesthesia,and the analgesic effect and other differences between the two groups were compared.Results In the study group,extubation time,recovery time,propofol dosage and postoperative VAS score were(150.2±15.2)min,(19.1±5.1)min,(738.2±36.5)mg and(4.2±0.7)points,respectively.The control group was(151.9±12.6)min,(22.6±7.3)min,(902.1±49.0)mg and(2.3±0.3)min,respectively,and the difference between the two groups was statistically significant(P＜0.05).The differences of heart rate,mean arterial pressure and before and after half an hour after surgery in control group were higher than those in study group,and the differences of norepinephrine,epinephrine and before and after surgery were higher than those in study group,with statistical significance(P＜0.05).The total complication rate of the study group was 7.2％,and that of the control group was 23.2％.The QoR score of the control group was lower than that of the study group,and the difference between the two groups was statistically significant(P＜0.05).Conclusion Preoperative and postoperative multi-point paravertebral nerve block combined with general anaesthesia has a better analgesic effect on patients undergoing radical lung cancer surgery,which can not only reduce the inflammatory reaction of the patients,but also have less impact on their haemodynamic indexes and lower rate of postoperative adverse reactions,and ultimately improve the quality of life of the patients.

There is increasing evidence that the activation of glucagon-like peptide-1 receptor(GLP-1R)can be used as a therapeutic intervention for cognitive disorders.Here,we have screened GLP-1 R targeted com-pounds from Scutellaria baicalensis,which revealed baicalein is a potential GLP-1 R small-molecule agonist.Mitophagy,a selective autophagy pathway for mitochondrial quality control,plays a neuro-protective role in multiple cognitive impairment diseases.We noticed that Glp1r knock-out(KO)mice present cognitive impairment symptoms and appear worse in spatial learning memory and learning capacity in Morris water maze(MWM)test than their wide-type(WT)counterparts.Our mechanistic studies revealed that mitophagy is impaired in hippocampus tissue of diabetic mice and Glp1r KO mice.Finally,we verified that the cognitive improvement effects of baicalein on diabetic cognitive dysfunction occur through the enhancement of mitophagy in a GLP-1 R-dependent manner.Our findings shed light on the importance of GLP-1 R for cognitive function maintenance,and revealed the vital significance of GLP-1R for maintaining mitochondrial homeostasis.Furthermore,we identified the therapeutic potential of baicalein in the treatment of cognitive disorder associated with diabetes.

【Objective】 To evaluate and analyze the impact of COVID-19 epidemic on inventory of red blood cells (RBCs)in local and municipal blood stations in China, and to provide reference for the management of public health emergencies. 【Methods】 Relevant data from 2018 to 2021 were collected, and the differences in the volume of qualified RBCs, the usage efficiency of inventory RBCs, the average daily distribution of RBCs,the blood distribution rate of RBCs prepared by 400 mL whole blood, the difference in the average storage days of RBCs at the time of distribution, the average daily inventory of RBCs and the time of the average daily inventory of RBCs to maintain the distribution in 24 local and municipal blood stations in China during the COVID-19 epidemic and non-epidemic periods were retrospectively analyzed. 【Results】 Compared with non-epidemic periods, the volume of qualified RBCs [(117 525.979 ±52 203.175)U] and the average daily distribution of RBCs [( 156. 468 ± 70. 186) U ] increased significantly, but the usage efficiency of inventory RBCs decreased(97.24%±0.51%) significantly (P<0.05).There was no significant difference in the blood distribution rate of RBCs prepared by 400 mL whole blood(73.88%±20.30%), the average storage days of RBCs distribution(13.040 ±3.486), the average daily stock quantity of RBCs[(2 280.542 ±1 446.538) U ] and the time of the average daily inventory of RBCs to maintain the distribution[(15.062 ±7.453) d] (P>0.5). 【Conclusion】 During the COVID-19 epidemic, the inventory management of RBCs operated well, the overall inventory remained relatively stable, the stock composition and storage period showed no significant change.

Objective:To investigate the mechanism of Candida albicans Int1 in regulating septin organization. Methods:A series of full-length and truncated fragments of Int1 were constructed and fused with green fluorescent protein (GFP). The intracellular localization of the fusion proteins was observed under a fluorescence microscope. The region in Int1 that was required for bud neck localization was identified. Full-length and fragments of Int1 were overexpressed in the yeast Saccharomyces cerevisiae and the changes in cell growth, cell morphology and septin organization were investigated to determine the functional region in Int1 that mediated the interaction with septin. Moreover, the co-localization of the region and septin was analyzed. Results:The full-length Int1 consisted of 1 661 amino acid residues. A middle region of 209 amino acid residues, Int1-M4 (739-947 aa), that could be localized at the bud neck during both small and large bud periods was identified. Overexpression of Int1-M4 led to significant growth defects, elongated bud and disorganized septin. In the cells with elongated bud, Int1-M4 and septin with abnormal structures could be co-localized.Conclusions:Int1-M4 (739-947 aa), the middle region of Int1 containing 209 amino acid residues, mediated the bud neck localization and the interaction with septin, playing an important role in regulating septin organization.

Objective:To explore the feasibility of early oral nutrition for gastric cancer patients after total gastrectomy based on propensity score matching.Methods:Using convenience sampling method, a retrospective analysis was conducted on the medical records of 755 patients who underwent total gastrectomy for gastric cancer at Jiangsu Subei People's Hospital from 2012 to 2020. A total of 454 patients who received early oral nutrition after surgery were included in the study group, while 301 patients who received conventional nutrition were included in the control group. The study group patients began eating orally on the first day after surgery, while the control group patients began eating orally after anal exhaust. The propensity score matching method was used to balance confounding factors between two groups.Results:A total of 203 pairs (406 cases) of patients were matched. After matching, there was no statistically significant difference in general data between the two groups ( P>0.05). The study group had lower dietary intake time, first anal exhaust time, hospital stay, incidence of abdominal infection, and incidence of anastomotic fistula compared to the control group, with statistically significant differences ( P<0.05) . Conclusions:Early oral nutrition for gastric cancer patients after total gastrectomy can promote intestinal function recovery, shorten hospital stay, and do not increase the risk of complications, including anastomotic fistula. It has the same acceptable tolerance as conventional nutrition, indicating that early oral nutrition after total gastrectomy is safe and feasible.
