Objective:To investigate associations of serum low-density lipoprotein cholesterol (LDL-C) with hematoma enlargement, early neurological deterioration (END), and outcome in patients with acute spontaneous intracerebral hemorrhage (ICH).Methods:"A multi-center registration study for spontaneous intracerebral hemorrhage in Inner Mongolia" (registration number: ChiCTR2000029494) database was used to include patients with ICH who completed their first head CT scan within 6 hours after onset, underwent blood lipid examination, CT follow-up within 24 hours of onset, and accurately measured hematoma volume using 3D Slicer software between June 2020 and September 2022. HE was defined as hematoma volume increasing >33% or >6 ml at 24 hours, or ventricular hematoma volume increasing ≥1 ml compared to the baseline. END was defined as an increase of ≥4 in the National Institutes of Health Stroke Scale (NIHSS) score from the baseline or death within 24 hours after onset. The follow-up was conducted at 3 months after onset, and the modified Rankin Scale score >2 was defined as poor outcome. Multivariate logistic analysis was used to determine the independent correlation between LDL-C and HE, END, and outcome. Results:A total of 338 patients with ICH were enrolled, including 206 males (60.9%). LDL-C was 2.39±1.22 mmol/L. Eighty-eight patients (26.0%) developed HE, 67 (19.8%) developed END, and 162 (47.9%) had poor outcome at 3 months. Multivariate logistic analysis showed that after adjusting for confounding factors, there was a significant independent negative correlation between LDL-C and HE (odds ratio 0.312, 95% confidence interval 0.208-0.467; P<0.001) and END (odds ratio 0.408, 95% confidence interval 0.275-0.606; P<0.001), but not with the outcome at 3 months. Conclusion:Lower LDL-C is associated with HE and END in patients with ICH, but not with the outcome.

Aim To investigate the changes in the proliferation and apoptosis of Siha cells after knocking down Rho GTPase-activating protein 30(ARHGAP30).Methods After designing specific shARHGAP30 primers and connecting them to the pLKO.1 vector,we transformed them into Escherichia coli competent cells,then co-transfecting them with lentiviral helper plasmids into HEK-293T cells.We collected and filtered cell supernatant to obtain the vi-rus to infect Siha cells.RT-qPCR and Western blot were used to detect knockdown efficiency,as well as changes in the expression of Bax and Bcl-2 after trans-fection.The CCK-8 method was employed to measure the proliferation level of cells after knockdown.Results After successful construction of a lentiviral plasmid with knockdown of the ARHGAP30 gene and establish-ment of stably transfected Siha cells,ARHGAP30 tran-scription and translation(P＜0.01)in Siha cells de-creased,Bax/Bcl-2 significantly decreased(P＜0.01),indicating decreased apoptosis and increased cell proliferation(P＜0.01).Conclusions This study suggests the involvement of ARHGAP30 in the proliferation and apoptosis of Siha cells,and regulating the ARHGAP30 gene may interfere with the occurrence and development of cervical cancer.

In this study,the immunological characteristics of the PhoP protein were explored with a two-component system of Mycobacterium tuberculosis(Mtb).Bioinformatics was used to predict the B and T cell epitopes of the PhoP protein.A re-combinant expression plasmid was constructed by PCR analysis of the phoP sequence and cloning into the prokaryotic expres-sion vector pET-28a(+).Competent Escherichia coli BL21 cells were transformed with the recombinant plasmid and expres-sion was induced with IPTG.The recombinant PhoP protein was purified by affinity chromatography.Serum levels of PhoP-specific antibodies in Mtb-infected mice and tuberculosis(TB)patients were analyzed with an ELISA.BALB/c mice were im-munized with the PhoP recombinant protein by intramuscular injection.Sera of mice were collected and antibody titers were detected with an ELISA and specificity was assessed by West-ern blot analysis.Mouse splenocytes were isolated and the pro-portions of IFN-y-positive cells and cytokine levels were detec-ted with an ELISpot and ELISA,respectively.Bioinformatics i-dentified 24 B cell and 11 T cell epitopes of the PhoP protein.A prokaryotic recombinant vector of PhoP was successfully con-structed and the recombinant PhoP protein was obtained by purification.Specific antibody levels to PhoP in sera of Mtb in-fected mice and TB patients increased significantly,with preci-sion of 99.9％and 82.5％,and specificity of 100％,respectively.PhoP protein immunization successfully induced production of specific antibodies in mice.Stimulated by antigens in vitro,IL-2 and IFN-γ levels were significantly increased in the splenocytes of immunized mice.Immunization with the PhoP protein induce a humoral immune response and Thl-dominated cellular immu-nity,indicating that the PhoP protein was immunogenic with diagnostic efficacy for TB.These results lay a foundation to clari-fy the role of PhoP in Mtb infection and application for diagnosis and prevention of TB.

Objective:To investigate the value of immunoglobulin heavy chain(IgH)gene rearrangement in monitoring minimal residual disease(MRD)in multiple myeloma(MM)received autologous hematopoietic stem cell transplantation(auto-HSCT).Methods:The clinical data of 26 MM patients who received auto-HSCT in the Department of Hematology,Wuhan First Hospital from 2018 to 2022 were collected.IgH rearrangement was detected by multiplex PCR combined with capillary electrophoresis fragment analysis to evaluate minimal residual disease(MRD),and the outcome of the disease was analyzed statistically.Results:Among the 26 MM patients,18 were males and 8 were females,with a median age of 59(41-70)years.The median follow-up time after transplantation was 33(7-52)months.Compared with the IgH rearrangement negative group(n=17),the proportion of CR and sCR of patients with IgH rearrangement positive in bone marrow samples before auto-HSCT at 3 months after transplantation was lower(1/9 vs 14/17),and the duration of remission(DOR)after transplantation was shorter(10.78±4.35 vs 15.88±5.22 months),with statistically significant difference in DOR between the two groups(P＜0.05).Compared with IgH rearrangement negative group(n=21),the proportion of CR and sCR of patients with positive IgH rearrangement results from peripheral blood stem cell collection at 3 months after transplantation was lower(0/5 vs 15/21),the duration of remission(DOR)after transplantation was shorter(9.60±4.83 vs 15.19±5.11 months),and the difference in DOR between the two groups was statistically significant(P＜0.05).During the follow-up period,5 patients(5/9)with positive IgH rearrangement results in bone marrow specimens died,and all patients with negative IgH rearrangement results survived.Four patients(4/5)with positive IgH rearrangement results by peripheral blood stem cell samples died,while one patient(1/21)with negative IgH rearrangement results died.In both bone marrow and peripheral blood stem cell samples,the survival time of IgH rearrangement-positive patients after transplantation was shorter than that of IgH rearrangement-negative patients(P＜0.05).Logistic regression analysis showed that gender,disease stage,the proportion of bone marrow smear plasma cells at initial diagnosis,stem cell mobilization plan,efficacy evaluation before transplantation(≥ CR and＜CR),and CD34+cell count had no effect on IgH rearrangement results of stem cell collection(P＞0.05).Conclusion:By detecting IgH rearrangement of MM patients receiving auto-HSCT,the depth of MRD can be further evaluated,which has a certain guiding significance for the efficacy and prognosis of the disease.

Objective:To investigate the effect of genetic polymorphism of MTHFR C677T (rs1801133) on methotrexate (MTX) related toxicity in pediatric mature B-cell lymphoma patients. Methods:Fifty-eight intermediate and high risk patients under 18 years of age with mature B-cell lymphoma who received 5 g/m2 MTX (24 h intravenous infusion) in Sun Yat-sen University Cancer Center from August 2014 to December 2021 were included,and their toxicity of high-dose MTX (HD-MTX) were monitored and analyzed. Results:Among the 58 pediatric patients,the number of CC,CT,and TT genotypes for MTHFR C677T was 33,19 and 6,respectively. A total of 101 courses of HD-MTX therapy were counted,of which plasma MTX level>0.2 μmol/L at 48 h post-MTX infusion were observed in 35 courses,≤0.2 μmol/L in 66 courses. Inter-group comparison showed that plasma MTX level>0.2 μmol/L at 48 h post-MTX infusion increased the risk of developing oral mucositis (P<0.05). Compared with wild-type (CC genotype),patients in the mutant group (CT+TT genotype) were more likely to develop myelosuppression,manifested as anemia,leucopenia,neutropenia and thrombocytopenia. However,plasma MTX level at 48 h was not associated with MTHFR C677T gene polymorphism. Conclusion:The risk of developing oral mucositis in children with mature B-cell lymphoma is associated with plasma MTX concentration. Polymorphism of MTHFR C677T gene is not related to plasma MTX concentration in children with mature B-cell lymphoma,but is related to grade Ⅲ to Ⅳ hematological toxicity.

Objective:To investigate the safety,efficacy,and prognosis of high-dose melphalan in combination with autologous hematopoietic stem cell transplantation (ASCT) for the treatment of multiple myeloma (MM). Methods:The clinical data of 17 patients with newly diagnosed MM who underwent ASCT as first-line consolidation therapy at the Yijishan Hospital of Wannan Medical College from March 2020 to October 2022 were retrospectively analyzed. The safety,efficacy,and prognosis of this treatment approach were evaluated. Results:Of the 17 patients,10 were male and 7 were female,with a median age of 56 (45-64) years. The stem cell engraftment rate was 100％,with a median neutrophil engraftment time of+10 (9-12) days and a median platelet engraftment time of+12 (10-21) days. The incidence of oral mucositis and intestinal infection after transplantation was 100％,with 2 cases of pulmonary infection,1 case of urinary tract infection,1 case of skin infection,and 11 cases of transient elevation of serum amylase. After transplantation,13 patients achieved a complete response (CR) or better,and the CR rate showed an increasing trend compared to before transplantation (13/17 vs 8/17;P=0.078). The median follow-up time was 18 (6-36) months,and 15 patients survived without progression,1 patient experienced disease progression,and 1 patient died due to clinical relapse and abandonment of treatment. The 2-year overall survival (OS) rate and progression-free survival (PFS) rate were approximately 90.0％ and 83.9％,respectively. Conclusion:High-dose melphalan in combination with ASCT as first-line consolidation therapy for MM can enhance the depth of patient response,further improve therapeutic efficacy,and the transplant-related complications are controllable,making it a viable option worth promoting in clinical practice.

Objective:To investigate the effect of sertraline hydrochloride combined with compound chamomile lidocaine gel in the treatment of premature ejaculation(PE).Methods:We selected 80 cases of PE treated in our hospital from June 2021 to May 2023 and equally randomized them into a control and an observation group,the former medicated with compound chamomile lidocaine gel while the latter with sertraline hydrochloride in addition,both for 6 weeks.We recorded and compared the intravaginal ejaculation latency time(IELT),the number of successful sexual intercourses per week,the Premature Ejaculation Diagnostic Tool(PEDT)scores,and the incidence of adverse reactions between the two groups of patients.Results:After the treatment,the IELT was signif-icantly longer([5.39±1.17]vs[2.49±0.73]min,P＜0.05),the weekly number of successful sexual intercourses remarkably higher(1.82±0.45 vs 0.93±0.19,P＜0.05)and the PEDT scores markedly lower(7.42±2.04 vs 9.85±2.36,P＜0.05)in the observation than in the control group,but no statistically significant differences were observed in the baseline PEDT scores or the incidence of adverse reactions between the two groups(P＞0.05).Conclusion:Sertraline hydrochloride combined with com-pound chamomile lidocaine gel is definitely effective in the treatment of PE,which can significantly improve the patients'quality of sexual life,with a high safety and low incidence of adverse reactions.

AIM To investigate the effects of Xinyue Capsules on the expression of glycerophospholipid metabolizing enzymes in isoproterenol(ISO)-induced rat heart tissue and primary myocardial cells of neonatal rats.METHODS The SD rats were randomly divided into the normal group,the model group,the Xinyue Capsules intervention group and Xinyue Capsules control group,with 8 rats in each group.The rat model of cardiac hypertrophy was established by 14 days consecutive intraperitoneal injection of ISO(30 mg/kg).Prior to the modeling,once daily administration of 0.393 g/kg Xinyue Capsules was given by gavage from 3 days in advance to the end of the experiment.After the last administration,the procurement of blood from abdominal aorta,the left and right ventricles were processed.And the rats had their indices levels of the heart,the left ventricle and the right ventricle measured;their pathomorphological changes of myocardial tissue observed using HE staining;their expressions of cardiac hypertrophy-related myocardial embryonic genes ANP,β-MHC and α-SKA mRNA detected using RT-qPCR method;and their serum TC,TG,LDL-C and HDL-C levels detected by biochemical method.In in vitro experiment,the neonatal rat model of myocardial hypertrophy was induced by exposure to ISO 1 μmol/L for 24 h.The investigation of the effect of Xinyue Capsules 12.5 μg/mL on ISO-induced myocardial hypertrophy was conducted by detection of myocardial cell area,embryo genes related to cardiac hypertrophy and myocardial cells protein cuntent.The further anti-cardiac hypertrophy mechanism of Xinyue Capsules research was conducted using RT-qPCR and Western blot to detect the gene and protein expressions of phospholipase A2(PLA2G6),phospholipase A1 member A(PLA1A)and lecithin cholesterol acyltransferase(LCAT)in left ventricle tissue and myocardial cells of each group.RESULTS The in vivo experimental result showed that compared with the normal group,the model group displayed increased indices levels of the heart,the left ventricle and the right ventricle and cross-sectional area of left ventricular myocytes(P＜0.05);and up-regulated expressions of ANP,β-MHC,α-SKA mRNA and PLA2G6,PLA1A and LCAT mRNA and proteins in the left ventricle(P＜0.05);and increased levels of serum TC,TG and LDL-C(P＜0.05);and decreased HDL-C level(P＜0.05).However,the intervention of Xinyue Capsules inhibited the changes of the aforementioned indices(P＜0.05).The in vitro experimental result revealed that Xinyue Capsules inhibited the ISO-induced increases of myocardial cell surface area and myocardial cell protein level,the up-regulation of ANP,β-MHC,α-SKA mRNA expressions and the PLA2G6,PLA1A,LCAT mRNA and protein expressions as well(P＜0.05).CONCLUSION Xinyue Capsules can improve the ISO-induced cardiac hypertrophy in rats,and its mechanism may be associated with its regulation upon the expressions of glycerophospholipid metabolism-related enzymes PLA2G6,PLA1A and LCAT.

Objective:To analyze the intrauterine ultrasound manifestations and postnatal follow-up outcomes of fetuses with 2q13 microdeletion.Methods:This retrospective study involved 23 cases of 2q13 microdeletion, diagnosed via amniotic fluid chromosome karyotyping and single nucleotide polymorphism-array (SNP-array) following amniocentesis, between January 1, 2018, and September 1, 2022, at Wuxi Maternity and Child Health Care Hospital. Descriptive statistical analysis was applied to prenatal diagnostic indications, intrauterine ultrasound findings, prenatal diagnosis results, and postnatal follow-up outcomes.Results:(1) The prenatal diagnostic indications for the 23 cases of 2q13 microdeletion included seven cases (30.4%) of high-risk serological screening, six cases (26.1%) of increased nuchal translucency (NT), two cases (8.7%) of fetal heart defects, two cases (8.7%) of advanced maternal age, two cases (8.7%) of fetal choroid plexus cysts (one of which was also associated with high-risk serological screening), one case (4.3%) of suboptimal fetal nasal bone fusion, one case (4.3%) of non-invasive prenatal testing suggesting chromosomal abnormalities, one case (4.3%) of fetal obstructive polycystic kidneys, one case (4.3%) of fetal subependymal cysts, and one case (4.3%) of fetal growth restriction. (2) Intrauterine ultrasound findings included six cases (26.1%) of NT thickening, four cases (17.4%) of intrauterine growth restriction, two cases (8.7%) of fetal heart defects, two cases (8.7%) of choroid plexus cysts, one case (4.3%) of oligohydramnios, one case (4.3%) of suboptimal fetal nasal bone fusion, one case (4.3%) of short long bones in the fetus, one case (4.3%) of polyhydramnios with large fetal abdominal circumference, one case (4.3%) of large fetal abdominal circumference, short long bones, and subependymal cysts of the brain ventricles, and one case (4.3%) of fetal obstructive polycystic kidneys; the remaining six cases (26.1%) showed no abnormal ultrasound findings. (3) Chromosome karyotyping revealed three cases of chromosomal structural abnormalities, one case of sex chromosome numerical abnormalities, and the remaining 19 cases showed no abnormalities. Amniotic fluid SNP-array results indicated deletions ranging from 104 to 1 745 kb. Parental verification was performed in ten cases, showing maternal inheritance in four cases, paternal inheritance in five, and one case of a de novo mutation. (4) Four cases (17.4%) opted for pregnancy termination, while 19 cases (82.6%) resulted in live births. The 19 live-born children underwent telephone and child health follow-up, with ages at follow-up being 3 years (ranging from 9 to 58.8 months). Apart from two cases that did not undergo newborn congenital heart disease screening, the remaining 17 surviving infants were screened without any abnormalities. Five cases had abnormal growth and development during follow-up: one 18-month-old with mild language developmental delay, one 3-year-old plus 26 days with mild language developmental delay, one 18-month-old with language developmental delay, one 3-year-old with astigmatism, and one 30-month-old with refractive error in both eyes during a physical examination; the other 14 children showed no significant abnormalities in growth and development. Conclusions:The intrauterine ultrasound manifestations of fetuses with 2q13 microdeletion are non-specific, and most of them are inherited from their parents. Postnatal follow-up should pay attention to the development of the nervous system of children.

Objective:To investigate the correlation between serum visfatin level and the risk of relapse after radiofrequency ablation in patients with atrial fibrillation(AF).Methods:The clinical data of 1 120 patients with AF who were admitted to the First Affiliated Hospital of Xinjiang Medical University and treated with radiofrequency ablation from June 2020 to December 2021 were retrospectively analyzed, and the general data as well as the results of preoperative and postoperative 12 months 24 h echocardiography and laboratory test index were collected. Followed up for 12 months, the patients′recurrence of AF was observed, and the changes of preoperative and postoperative 12 months echocardiography and laboratory test index were compared between the patients with and without recurrence of AF; the risk factors affecting the recurrence of AF after radiofrequency ablation were analyzed by Logistic regression analysis, the correlation of visfatin level and the recurrence of radiofrequency ablation was analyzed by Pearson test.Results:The results of Logistic regression analysis showed that the patients′ age ( OR = 2.344), body mass index ( OR = 2.090), persistent AF ( OR = 3.655), hypertension ( OR = 3.529 ), coronary artery disease ( OR = 4.035), preoperative left atrial diameter (LAD) ( OR = 3.644 ), visfatin level ( OR = 2.136 ) and postoperative 12 months LAD ( OR = 2.046), left atrial volume index(LAVI) ( OR = 2.237), atrial natriuretic polypeptide (ANP) ( OR = 3.600), visfatin ( OR = 3.699), and highly sensitive C-reactive protein (hs-CRP) ( OR = 3.586) levels at 12 months postoperatively were risk factors for recurrence in AF patients ( P<0.05). In the recurrence group, there were no statistical differences in LAD, LAVI, ANP, visfatin, and hs-CRP levels at 12 months postoperatively compared with preoperative levels ( P>0.05). The results of Pearson test showed that there was a positive correlation between AF recurrence and visfatin level after radiofrequency ablation ( r = 0.420, P = 0.013). Conclusions:There are many factors affecting AF recurrence after radiofrequency ablation in patients with AF, the common ones are age, left heart enlargement, hs-CRP level, etc. Meanwhile, high level of visfatin before and after surgery is also an important factor of AF recurrence.
