ABSTRACT

Objective:To investigate the efficacy and safety of intravenous thrombolysis and antiplatelet therapy in patients with stroke warning syndrome (SWS), as well as influencing factors of the outcome in patients with SWS.Method:Patients with SWS admitted to the 521 st Hospital of Ordnance Group from June 1, 2018 to December 31, 2023 were retrospectively included. Some patients were treated with ateplase intravenous thrombolysis, followed by oral antiplatelet therapy; some patients only received antiplatelet therapy. The main outcome measure was the modified Rankin Scale score at 90 days after onset, with a score of 0-2 defined as good outcome. Results:A total of 35 patients with SWS were included, including 26 males (74.3%) with an age of 58.29±11.06 years. Nineteen patients (54.3%) received intravenous thrombolysis, and 27 (77.1%) had good outcome at 90 days. There was no statistically significant difference in demographic, baseline data, and good outcome between the intravenous thrombolysis group and the antiplatelet therapy group. One patient had new stroke and one had transient ischemic attack in the intravenous thrombolysis group. There were statistically significant differences in ABCD2 score, systolic blood pressure, low-density lipoprotein cholesterol, fasting blood glucose, highest National Institutes of Health Stroke Scale (NIHSS) score at onset, and symptom duration between the good outcome group and the poor outcome group (all P<0.05). Conclusions:The efficacy of intravenous thrombolysis is similar to that of antiplatelet drugs alone in treating SWS. ABCD2 score, systolic blood pressure, low-density lipoprotein cholesterol, fasting blood glucose, highest NIHSS score at onset, and duration of symptoms may be influencing factors for the outcome of patients with SWS.

ABSTRACT

OBJECTIVE To evaluate the efficacy and safety of dydrogesterone in the treatment of dysmenorrhea. METHODS The prospective ,random-controlled,open-labeland multicenter clinical study was adopted. A total of 108 women with dysmenorrhea were randomly assigned into dydrogesterone group and control group according to the ratio of 1∶1,with 54 patients in each group. Dydrogesterone group was treated with dydrogesterone 10 mg orally ,twice a day ,on the 5th-25th day of menstrual cycle ,for 3 menstrual cycles. Control group received Guizhi fuling capsule 0.93 g orally ,three times a day,since the end of menstrual bleeding to the third day of the next menstruation ,for 3 menstrual cycles. Main results were the changes of visual analogue scale (VAS)scores in 2 groups after 3 menstrual cycles ;secondary results were the changes of COX menstrual symptom scale (CMSS),quality life of 36-item short form (SF-36),levels of carbohydrate antigen 125(CA125)and interleukin 6(IL-6)after 3 menstrual cycles ;other findings included additional benefits and drug safety. RESULTS The results of intention to analysis data set and the follow-up study protocol analysis data set showed that VAS scores of 2 groups after treatment of dysmenorrhea for 1,2 and 3 menstrual cycles were lower than those before treatment ,the longer the treatment time ,the more obvious the decrease of VAS score (P<0.05),and VAS score decline of dydrogesterone group was better than that of control group(P<0.05). After 3 menstrual cycles ,both the two group showed significant reduction in the severity and duration scores of CMSS(P<0.05);and the decrease of the above scores in the dydrogesterone group was superior than in the control group (P< 0.05). After 3 menstrual cycles ,among 8 dimensions of SF- 36 scale,the scores of 7 dimensions in dydrogesterone group were significantly higher than those before treatment ,such as the scores of physiological function ,physical role ,physical pain , emotional function ,social function ,general health status and energy (P<0.05);the increase of the scores of four dimensions were higher than those in the control group ,such as physical pain ,social function ,general health status ,energy(P<0.05). There was no significant difference in the levels of CA 125 and IL- 6 between 2 groups before and after treatment (P>0.05). After 3 menstrual cycles,the menstrual cycle and menstrual period in the dydrogesterone group were shorter than those before treatment ,and the menstrual volume decreased (P<0.05);but there was no significant change in the above indexes of control group (P>0.05). After 3 menstrual cycles ,the incidence of adverse drug events and adverse reactions in dydrogesterone group was 32.69%(17/52)and 28.85%(15/52);no serious adverse drug events or adverse reactions such as thrombosis occurred in both groups. CONCLUSIONS Dydrogesterone can effectively reduce the VAS score ,also relieve dysmenorrhea-related symptoms ,and improve the quality of life. The efficacy of dydrogesterone is superior than that of Guizhi fuling capsule in treatment for dysmenorrheal ,without serious adverse reactions. It is well tolerated.

ABSTRACT

OBJECTIVES@#As a remedy for the failure of in vitro fertilization (IVF), rescue intracytoplasmic sperm injection (R-ICSI) has been widely carried out, but it has failed to significantly improve the fertilization rate and clinical pregnancy rate. Sperm DNA fragmentation index (DFI) was highly correlated with pregnancy outcome of artificial assisted reproduction. This study aims to investigate the effect of the sperm DFI on the outcome of R-ICSI and the clinical value of R-ICSI.@*METHODS@#This retrospective analysis was conducted among 140 infertile couples receiving R-ICSI in from January 2014 to December 2019. The subjects were assigned into a total fertilization failure (TFF)+low DFI group (R-ICSI after TFF and DFI<30%) (n=63), a TFF+high DFI group (R-ICSI after TFF and DFI≥30%) (n=16), a partial fertilization failure (PFF)+low DFI group (R-ICSI after PFF and DFI<30%) (n=52), a PFF+high DFI group (R-ICSI after PFF and DFI≥30%) (n=9). All transferred embryos were come from R-ICSI. The general clinical data [infertility duration, male age, female age, basal serum level of follicle stimulating hormone (FSH), basal serum level of luteinizing hormone (LH), antral follicle count, endometrial thickness of human chorionic gonadotropin (HCG) day, and eggs] and R-ICSI cycle outcomes (fertilization rate, normal fertilization rate, cleavage rate, good embryo rate, implantation rate, clinical pregnancy rate and live birth rate) were analyzed. In addition, the effect of R-ICSI on the fertilization outcome of conventional IVF total fertilization failure and partial fertilization failure was explored.@*RESULTS@#There was no significant difference in the general clinical data and R-ICSI cycle outcome between the TFF+low DFI group and the TFF+high DFI group (all P>0.05). There was no significant difference in the general clinical data between the PFF+low DFI group and the PFF+high DFI group (all P>0.05). The fertilization rate and normal fertilization rate in the PFF+low DFI group were significantly higher than those in the PFF+high DFI group (85.40% vs 72.41%, 71.90% vs 58.62%, respectively; both P<0.05). However, there was no significant difference in cleavage rate, good embryo rate, implantation rate, clinical pregnancy rate, and live birth rate between the 2 groups (all P>0.05). The R-ICSI cycle of TFF: A total of 79 fresh cycles, 57 fresh transplant cycles, a total of 761 unfertilized oocytes, and 584 M II oocytes were treated with R-ICSI, the fertilization rate was 83.22%, the normal fertilization rate was 75.51%, the cleavage rate was 98.15%, the good embryo rate was 40.74%, the implantation rate was 30.56%, and the clinical pregnancy rate was 43.86%; 29 live births were obtained. The R-ICSI cycle of PFF: A total of 61 fresh cycles, 31 fresh transplant cycles, a total of 721 unfertilized oocytes, and 546 M II oocytes were treated with R-ICSI; the fertilization rate was 83.33%, the normal fertilization rate was 69.78%, the cleavage rate was 97.36%, the good embryo rate was 44.39%, the implantation rate was 25.42%, and the clinical pregnancy rate was 45.16%; 12 live births were obtained.@*CONCLUSIONS@#In the case of partial fertilization failure of IVF, the sperm DFI affects the fertilization rate and normal fertilization rate of R-ICSI; whether it is a TFF of IVF or PFF of IVF, ICSI can be used as an effective remedy way.

ABSTRACT

Objective:To investigate the mechanism of Wnt5a in lentoid body (LB) induction from human embryonic stem cells (hESCs).Methods:A "three-stage" protocol was used for LB differentiation from hESCs in vitro, and Wnt5a level was modified by adding exogenous 500 ng/ml Wnt5a on day 18 as Wnt5a treatment group.Cells of control group and Wnt5a treatment group were collected on day 35.Cells were photographed by using the Zeiss Axio Observer Z1 microscope.Transcriptome sequencing was applied by Illumina.Genes with P value≤0.05 and fold change≥1.5 were identified as differentially expressed genes (DEGs). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were used to determine the biological functions of DEGs. Results:Compared with the control group, larger lentoid bodies were obtained in the Wnt5a treatment group.Transcriptome sequencing result showed that 478 genes were down-regulated and 201 genes were up-regulated in the Wnt5a treatment group compared with the control group, and Wnt5a up-regulated both lens cell differentiation and lens specific gene expression.Bioinformatics analysis result showed that most DEGs were involved in extracellular matrix remodeling, suggesting that Wnt5a regulated extracellular matrix remodeling during lens cell differentiation.The enrichment analysis result also showed that epithelial-to-mesenchymal transformation related processes were inhibited after Wnt5a treatment, suggesting that Wnt5a inhibited the abnormal differentiation of lens cells (especially lens epithelial cells) during lens cell differentiation.Wnt5a influenced the processes related to cytoskeleton remodeling.Conclusions:Wnt5a may act in lens cells through MAPK/ERK signaling pathways to affect ECM and cell cytoskeletal organization, which provides a new direction for studying lens development.

ABSTRACT

Objective To explore the folate receptor alpha(FRA)expression in different types and stages of in endometrial carcinoma(EC). The sensitivity and specificity of FRA testing were compared with CA125 to evaluate its diagnostic performance.Methods Serum from 50 cases of EC patients and 30 cases of normal patients was collected.Tissue from 83 cases of typeⅠEC and 30 cases of normal endometrium and typeⅡEC were collected. The expression of serum FRA was detected by ELISA.The expression ofserum CA125 was detected by electrochemi-luminescence.The expression of FRA and CA125 in tissues was detected by immunohistochemistry. Results The rate of elevated FRA expression of in typeⅠEC tissue was higher than that in typeⅡEC(P < 0.05). The rate of elevated FRA expression in type I EC was higher than that in the early stage(P < 0.05). The ROC curve showed that the sensitivity and specificity of FRA was higher than these of CA125′s. Further,they are higher in the com-bined serum FRA and CA125.Conclusions This study shows that the FRA expression level in endometrial carci-noma varies in different subtypes,indicating the potential different pathogeneses. The rate of elevated FRA expression in type I endometrial carcinoma was higher than that in the early stage. This provides the possibility for the application of FRA targeted fluorescent developer in advanced endometrial carcinoma meticulous surgery. Combination of FRA and CA125 have better diagnostic value in detecting EC.

ABSTRACT

Objective To observe the expression dynamics of lens-related transcription factors in human embryonic stem cell (hESC) differentiated into lentoid body(LB).Methods A "three-stage" protocol was used for LB directional differentiation from hESC in vitro.The hESC (D0) and three differentiation stages cells were collected to analyze the expression dynamics of lens development-associated transcription factors by high throughput RNA sequencing technology in hESC-induced LB.Western blot and cell immunofluorescence were used to observe the involved genes at protein level.Results During D0-D6,cells became more round and compact.And during D7-D18,cells morphology gradually changed to spindle.At the end of D35,three-dimensional and transparent structurelentoid body (LB) was obtained.RT-PCR results showed that the stem cell related genes reduced and the lens specific genes increased significantly,and the LB was characterized by the expression of crystallins.According to clustering analysis of high throughput sequencing,a distinct difference in transcription factors gene expression was observed between D0 and D32.Meanwhile,the difference between D6 and D18 was minimum.The expressions of preplacodal genes,including DLX3,DLX5,DLX6,HES1,HES4,OTX2 and EYA1 increased remarkably at the first induction stage and then decreased.Lens-specification gene SOX2 declined gradually and then increased.In addition,the expression of PAX6 increased during all three induction stages.Furthermore,lens-differentiation genes including MAB21L1,CMAF,PROXI and PITX3 had no significant change in the early induction stage,but increased significantly at the third induction stage.Conclusions The expression dynamics of lens development-associated transcription factors in the hESC induced LB corresponded to those in vivo,which indicate that this induction system can recapitulate early lens development well and lay the foundation of studying lens embryonic development andtranscription factor associated congenital lens diseases.

ABSTRACT

Objective To explore the therapeutic effect and clinical significance of pelvic floor rehabilitation technique in female with myofascial chronic pelvic pain (MCPP) by detecting the pressure pain thresholds (PPTs). Methods One hundred healthy female (control group) and 324 female MCPP patients (observation group) from January 2009 to December 2016 were selected. Automatic body surface and vaginal pressure pain detector was applied to detect two groups′PPTs of the 34 spots. The difference of PPTs at each spot was analyzed in two groups. In addition, 51 patients with moderate and severe MCPP were selected to record the changes of PPTs and pain scores before and after the treatment of pelvic floor rehabilitation technique. Results The average PPTs of the abdomen, vulva, pelvic floor and vaginal front and back fornix, bilateral adnexa uteri and sacrouterine ligament in the observation group were significantly lower than those in the control group (P<0.01 or<0.05). The average PPTs of the abdomen, vulva, pelvic floor muscles and vaginal front and back fornix, bilateral adnexa uteri and sacrouterine ligament of 51 MCPP patients after treatment were significantly higher than those before treatment (P<0.01). After treatment, PPTs and pain scores of the pelvic floor muscles, bilateral adnexa uteri, bilateral sacrouterine ligament, bilateral sacral spine ligament and vaginal front and back fornix were negatively correlated (r =- 0.78 to- 0.19, P = 0.01 to 0.04); there was a negative correlation between the PPTs and pain scores of the left and right latissimus dorsi (r=-0.28, P=0.04;r=-0.32, P=0.02). The complete remission rate with the pelvic floor rehabilitation technique in 51 patients with MCPP was 9.8%(5/51), the significant remission rate was 90.2%(46/51), and the total remission rate was 100.0% (51/51). Conclusions Compared with the normal healthy ones, female with MCPP has lower PPTs in the abdomen, perineum, vagina and pelvic floor. The effect of pelvic floor rehabilitation technique on MCPP is well, which can increase patients′PPTs to reduce pain scores. It is a worthwhile method to treat these diseases.

ABSTRACT

BACKGROUND:Previous studies have shown that erythropoietin can protect neurons and promote nerve regeneration. OBJECTIVE:To explore the therapeutic effect of erythropoietin gene-modified bone marrow mesenchymal stem celltransplantation via caudal vein on rat cerebral infarction. METHODS:Western blot assay was used to identify the expression of exogenous erythropoietin in bone marrow mesenchymal stem cells. A model of middle cerebral artery occlusion was established in Wistar rats using thread method. And then, model rats were randomly divided into model group (PBS injection via the caudal vein), transplantation group (transplantation of bone marrow mesenchymal stem cellsuspension), erythropoietin group (transplantation of erythropoietin-transfected bone marrow mesenchymal stem cellsuspension). Neurologic function was assessed at 3 days, 1, 2, 3, 4 weeks after celltransplantation. Four weeks after transplantation, the rats were decapitated after anesthesia to take brain tissues for RT-PCR detection of Bcl-2/Bax gene expression. cellapoptosis was measured by TUNEL. Hematoxylin-eosin staining and fluorescence microscopy were employed to observe the survival and distribution of PKH26-labeled bone marrow mesenchymal stem cells. RESULTS AND CONCLUSION:Western blot results showed that erythropoietin-transfected bone marrow mesenchymal stem cells could express the erythropoietin in vitro. At 1, 2, 3, 4 weeks after transplantation, the neurological defect scores in the transplantation group and erythropoietin group were significantly lower than those in the model group (P<0.05, P<0.01). The expression of bcl-2 gene in the infarct region was significantly higher in the erythropoietin group than the transplantation and model groups (P<0.05), but the expression of bax was significantly decreased (P<0.05). In the erythropoietin group, the number of apoptotic cells was reduced, and the number of PKH26 positive cells was increased as compared with the other two groups (P<0.05). These findings indicate that the transplantation of erythropoietin-modified bone marrow mesenchymal stem cells via caudal vein can significantly improve the neurological function in the rats with cerebral infarction.

ABSTRACT

Objectives To investigate the clinical significance of the airway inflammation mediators,eosinophil cationic protein (ECP) and urinary leukotriene E4 (LTE4),in children with respiratory syncytial virus (RSV) bronchiolitis. Methods A total of 120 inpatients with RSV bronchiolitis were classified into atopic and non-atopic groups. And 30 healthy subjects were se-lected as normal controls. Urinary LTE4 was determined by ELISA and ECP concentration in nasopharyngeal secretions (NPS) was tested by UniCAP100 allergen detector. The differences among groups were compared. Results The urinary LTE4 level in atopic group (172.21 ± 67.29 pg/ml) was elevated significantly (P<0.01) than that of non-atopic group (78.21 ± 28.78 pg/ml) and control group (44.22±16.14pg/ml). Significance was also found between non-atopic and control groups (P<0.01). Statistical anal-ysis indicated that urinary LTE4 positively correlated to serum IgE and ECP in children with RSV bronchiolitis (r=0.57,0.49;P<0.01). Conclusions The level of urinary LTE4 and ECP in NPS can provide the reference for treatment and prognosis of children with RSV bronchiolitis.

ABSTRACT

BACKGROUND:Danhong injection, scavenging free radicals and inhibiting lipid peroxidation, can improve microenvironment injury after cerebral infarction. OBJECTIVE:To explore the influence of bone marrow mesenchymal stem cel s combined with Danhong injection on expression of GAP-43 and Bcl-2 after cerebral infarction in rats. METHODS:Sixty Wistar rats were selected to prepare models of cerebral infarction by middle cerebral artery occlusion and then randomly divided into control group, bone marrow mesenchymal stem cel group, and combination group. Control group received tail vein injection of PBS. Bone marrow mesenchymal stem cel group received tail vein injection of 2.5×109/L bone marrow mesenchymal stem cel suspension. Combination group received injection of 2.5× 109/L bone marrow mesenchymal stem cel suspension+2 mL/kg Danhong injection, for 5 consecutive days, once a day. RESULTS AND CONCLUSION:There were no significant differences in the neurological dysfunction scores among the three groups at 24 hour and 3 days after implantation (P>0.05). The neurological dysfunction scores in the ombination group were significantly lower than those in the bone marrow mesenchymal stem cel group and control group at 1 and 2 weeks after transplantation (P<0.05). In the combination group, GAP-43 and Bcl-2 expression was significantly higher than the bone marrow mesenchymal stem cel group and control group (P<0.05). Bone marrow mesenchymal stem cel transplantation combined with Danhong injection can significantly promote the local expression of GAP-43 and Bcl-2 after cerebral infarction, and has obvious inhibitory effects on cel apoptosis in rats with cerebral infarction.
