ABSTRACT

Objective:To prepare polyvinyl alcohol (PVA) and hydroxyapatite (HA) composite embolization microspheres and investigate their physicochemical properties.Methods:PVA/HA composite embolization microspheres were prepared by reverse suspension polymerization, using PVA and HA as dispersed phases, liquid paraffin containing sorbitan fatty acid ester as the continuous phase, and glutaraldehyde as the cross-linking agent. The morphology, particle size distribution, and microscopic morphology of PVA/HA composite embolization microspheres were observed by optical microscopy and scanning electron microscopy. The chemical structure of PVA/HA composite embolization microspheres and the elasticity, drug loading, and drug release properties of PVA/HA composite bolus microspheres were characterized by Fourier infrared spectroscopy.Results:The PVA/HA composite embolization microspheres were internal, porous round spheres with a particle size distribution of 50-300 μm. The elastic properties of PVA/HA composite embolization microspheres were(13.6±0.145) kPa, which was 2.28 times that of PVA microspheres, and the drug loading capacity and encapsulation efficiency were (76.80±1.22) mg/g and (38.4±12.7)%, respectively. The maximum cumulative release rate of the microspheres within 7 days was (7.37±0.101)%, and the maximum cumulative release was (256.2±9.8) μg.Conclusions:PVA/HA composite embolization microspheres have good mechanical properties and drug-loading and drug-releasing properties, which provide an important reference for their use as medical devices.

ABSTRACT

BACKGROUND@#Microglia plays an indispensable role in the pathological process of sleep deprivation (SD). Here, the potential role of microglial CX3C-chemokine receptor 1 (CX3CR1) in modulating the cognition decline during SD was evaluated in terms of microglial neuroinflammation and synaptic pruning. In this study, we aimed to investigat whether the interference in the microglial function by the CX3CR1 knockout affects the CNS's response to SD.@*METHODS@#Middle-aged wild-type (WT) C57BL/6 and CX3CR1-/- mice were either subjected to SD or allowed normal sleep (S) for 8 h to mimic the pathophysiological changes of middle-aged people after staying up all night. After which, behavioral and histological tests were used to explore their different changes.@*RESULTS@#CX3CR1 deficiency prevented SD-induced cognitive impairments, unlike WT groups. Compared with the CX3CR1-/- S group, the CX3CR1-/- SD mice reported a markedly decreased microglia and cellular oncogene fos density in the dentate gyrus (DG), decreased expression of pro-inflammatory cytokines, and decreased microglial phagocytosis-related factors, whereas increased levels of anti-inflammatory cytokines in the hippocampus and a significant increase in the density of spines of the DG were also noted.@*CONCLUSIONS@#These findings suggest that CX3CR1 deficiency leads to different cerebral behaviors and responses to SD. The inflammation-attenuating activity and the related modification of synaptic pruning are possible mechanism candidates, which indicate CX3CR1 as a candidate therapeutic target for the prevention of the sleep loss-induced cognitive impairments.

ABSTRACT

Objective:To evaluate the sleep disorders in patients with Parkinson′s disease (PD) with different onset sides, and to analyze the correlation between PD kinesia-onset side and sleep disorders.Methods:A total of 658 patients with primary PD admitted to the Special Outpatient Department of Parkinson′s disease in Fujian Medical University Union Hospital from January 2015 to March 2021 were collected. According to the onset side of motor symptoms, they were divided into the left group (313 cases) and the right group (345 cases). The medical history collection and physical examination were conducted to evaluate the motor symptoms, non-motor symptoms [Non-Motor Symptom Scale (NMSS)], depression state and cognitive function of the patients. Parkinson′s Disease Sleep Sclale-2 (PDSS-2) and the Rapid Eye Movement Sleep Behavior Disorder Screening Questionnaire (RBDSQ) were used to evaluate and analyze their sleep status, and comparisons were made between groups. Binary multivariate Logistic regression analysis was used to access the risk factors associated with sleep disorders in Parkinson′s disease.Results:The scores of daytime fatigue [2.00(0, 4.00)] and unexplained limb pain [4.00(0, 4.00)] in NMSS assessment of PD patients in the left onset group were significantly higher than those in the right onset group [1.00(0, 3.00), Z=-2.545, P=0.001; 2.00(0, 4.00), Z=-2.797, P=0.005]. There was no significant difference in the total score of PDSS-2 between the two groups, but there were significant differences in limb restlessness, periodic limb activity, muscle spasm and early drowsiness between the two groups. In the evaluation of rapid eye movement sleep behavior disorder (RBD), the total score of RBDSQ in the left onset group [2.00(0, 4.00)] was significantly higher than that in the right onset group [1.00(0, 3.00), Z=-4.363, P<0.001]. The incidence of dream content, nocturnal behavior, nocturnal exercise, self-injury and bed partner in dream, abnormal behavior at night, nighttime awakening, dream memory and sleep disorder in the left onset group was also higher than that in the right onset group. In addition, binary multivariate Logistic regression showed that PD-related sleep disorders were associated with onset of advanced age ( OR=1.037, 95% CI 1.018-1.057, P<0.001), course of disease ( OR=1.014, 95% CI 1.010-1.018, P<0.001) and onset of abnormal postural gait ( OR=1.505,95% CI 1.058-2.141, P=0.023). RBD in patients with PD was associated with left onset ( OR=2.215,95% CI 1.395-3.515, P=0.001), advanced age onset ( OR=1.045,95% CI 1.019-1.072, P=0.001) and course of disease ( OR=1.014,95% CI 1.009-1.019, P<0.001). Conclusions:PD patients with left onset are more likely to have sleep disorders such as limb restlessness, periodic limb activity, muscle spasm and early drowsiness. At the same time, the incidence and severity of RBD in patients with left onset of PD are significantly higher than those of patients with right onset of PD. The onset side of motor symptoms of PD is an important factor affecting sleep disorders, and the onset of left side may be a risk factor for PD patients with RBD.

ABSTRACT

Objective:To investigate the clinical manifestations of familial amyloid multiple neuropathy (FAP) caused by Ala117Ser mutation, and to improve the clinical recognition of FAP.Methods:The clinical manifestations, electrophysiological examination, pathology and gene mutation characteristics of a case of FAP, who admitted to Fujian Medical University Union Hospital on November 25, 2014, were analyzed, and the literatures on the FAP cases caused by Ala117Ser mutation were reviewed and summarized.Results:The patient was a 59-year-old male from Fujian province. The first symptom was numbness in the extremities, followed by obvious autonomic nerve symptoms and motor disorder, and fatal cardiac dysfunction occurred in the later stage of the disease. The skin biopsy showed amyloidosis, and transthyretin gene analysis indicated the mutation of c.349G>T p.Ala117Ser. The clinical manifestations of FAP caused by Ala117Ser mutation reported in literatures are consistent with this case. And the reported FAP cases in China are concentrated in southern regions such as Fujian Province and Guangdong Province.Conclusions:Ala117Ser mutation in FAP patients is usually late onset and clinically manifested as multiple sensorimotor peripheral neuropathy, accompanied by prominent autonomic symptoms. The distribution of the patients has significant regional characteristics. Histopathological and genetic tests for the clinical diagnosis are of great significance.

ABSTRACT

Objective:To observe the intrinsic association between cognitive function in patients with Parkinson′s disease (PD) and retinal structural changes in retina nerve fiber layer thickness, macular volume and macular thickness.Methods:A total of 36 patients with PD and 12 normal controls matched with age and sex were selected randomly. Examinations of Montreal Cognitive Assessment (MoCA), Mini-Mental State Examination (MMSE), Unified Parkinson′s Disease Rating Scale Ⅲ (UPDRS-Ⅲ), Hoehn-Yahr stage were performed in all subjects. The PD patients were divided into three groups according to the score of MoCA: PD without cognitive impairment (PD-NCI; n=12), PD with mild cognitive dysfunction (PD-MCI; n=13) and PD dementia (PDD; n=11). The retinal nerve fiber layer thickness, macular volume and thickness which were corrected with body mass index (BMI) were determined and analyzed by optical coherence tomography imaging. Results:The total RNFL thickness (μm/BMI) of the PD with cognitive impairment group (PD-MCI group: 3.55±0.12 ( t=2.552, P=0.014), PDD group: 3.07±0.18 ( t=4.122, P=0.000)) was thinner than that of the normal control group (4.05±0.16). The RNFL thickness in each quadrant of the PD with cognitive impairment group (PD-MCI group and PDD group) was thinner than those of the normal control group. The RNFL thickness gradually became thinner with the cognitive impairment increasing ( r=0.558 3, P<0.001). The macular volume (mm 3/BMI) of PD group (PD-NCI group: 0.274±0.010 ( t=2.523, P=0.015), PD-MCI group: 0.268±0.010 ( t=2.848, P=0.007), PDD group: 0.266±0.010 ( t=2.604, P=0.013)) was smaller than that in the normal control group (0.316±0.010), and the macular volume gradually decreased with the severity of cognitive impairment ( r=0.234 1, P=0.024). The macula thickness in each subgroup of PD was thinner than that of the normal control group. The macula thickness gradually became thinner with the cognitive impairment increasing ( r=0.283 9, P<0.001). The macular thickness (normal controls: (10.67±0.12) μm/BMI, PD group: (9.51±0.07) μm/BMI, t=8.312, P<0.001) and volume (normal controls: (0.316±0.010) mm 3/BMI, PD group: (0.270±0.010) mm 3/BMI, t=3.570, P<0.001) became thinner and smaller in patients with PD. Conclusions:In patients with PD, the thickness of the retina nerve fiber layer, the volume and thickness of the macula become thinner/smaller with the severity of cognitive impairments increasing. Macular thickness and volume in patients with PD appear thinner/smaller, which can be used as a valuable biological marker in the early stage of PD. The retina nerve fiber layer thickness in patients with PD becomes thinner, which may be accompanied by cognitive impairment.

ABSTRACT

Objective:To explore the value of magnetic resonance diffusion kurtosis imaging (DKI) in the early diagnosis of Parkinson′s disease (PD).Methods:Thirty patients with early PD who were admitted to the Fujian Medical University Union Hospital From December 2016 to September 2017 were selected as case group, and 20 healthy persons in the same period were selected as healthy control group. 3.0 T GE magnetic resonance DKI was used to analyze olfactory related brain regions of the case group and the control group, the statistical differences were compared between the two groups in fractional anisotropy (FA), mean diffusion (MD), mean kurtosis (MK) values of olfactory cortex, and the correlation between MK values of olfactory cortex of the case group and age, disease course, Hoehn-Yahr (H-Y) stage, olfactory test, cognitive function evaluation was analyzed. Receiver operating characteristic (ROC) curve was used to determine the best diagnostic cutoff value of olfactory cortical MK in PD.Results:The left amygdala MK between the PD group (0.595±0.037) and the control group (0.647±0.091) showed statistically significant difference ( t=-2.183, P=0.037). ROC curve was drawn according to the MK value of the left amygdala of the PD group: the best diagnostic cutoff value was 0.597, the sensitivity was 65.0%, and the specificity was 52.2%. There was a statistically significant difference between the PD group and the control group in Montreal Cognitive Assessment (MoCA; 21.03±3.71 vs 24.25±1.65, t=-3.636, P=0.001) and Frontal Assessment Battery (FAB) scores (13.93±1.36 vs 15.00±1.25, t=-2.086, P=0.042), and there was negative correlation between MoCA, FAB scores and H-Y stage ( r=-0.548, P=0.007; r=-0.465, P=0.025). There was a positive correlation between MK value of the right direct gyrus of the PD group and MoCA evaluation results ( r=0.447, P=0.032). Conclusions:The left amygdala DKI can be used as a biomarker of PD in the early stage, which is helpful for the early diagnosis of PD. MoCA and FAB scales can be used as tools to monitor the progress of PD cognitive impairment. PD cognitive dysfunction may be related to impairment of frontal lobe function.

ABSTRACT

Objective:To analyze the epidemiological characteristics of children with hand, foot, and mouth disease (HFMD) and herpetic angina (HA) in Wenzhou City and the influence of meteorological factors on the pathogenesis, and to provide basis for early warning and disease prevention.Methods:A total of 62 809 children diagnosed with HFMD and 56 005 with HA in the 2nd Affiliated Hospital and Yuying Children′s Hospital of Wenzhou Medical University during 2012 to 2017 were enrolled. The meteorological factors during 2012 to 2017 were collected monthly. The data were analyzed using Spearman rank correlation and multivariant linear stepwise regression model.Results:The number of cases of HFMD and HA began to rise in the spring, and decreased after reaching the peak from May to July. Then there was a secondary peak from September to December, and the incidence decreased significantly in winter. Univariate correlation analysis showed that the effects of different meteorological factors on HFMD and HA were basically the same. Multivariant linear stepwise regression analysis showed that there was a positive correlation between monthly mean temperature (X) and the number of HFMD cases. The regression equation was Y=-161.450+ 53.828X ( F=22.250, P<0.01). Monthly mean relative humidity (X 1) and temperature (X 2) were positively associated with the number of HA cases. The regression equation was Y=-3 521.196+ 46.814X 1+ 41.762X 2 ( F=18.351, P<0.01). Conclusions:The trends of onset time of HFMD and HA are similar. The meteorological factors are closely related to HFMD and HA, and their incidence trends are significantly affected by meteorological changes.

ABSTRACT

Objective:To investigate the changes of PERK,Runx2,osterix,RANKL and OPG in bone tissue of the female rats with experimental postmenopausal osteoporosis(PMOP)before and after treatment,and to elucidate the role of PERK signaling pathway in PMOP.Methods:The ovariectomized rats were reproduced to osteoporosis models.A total of 45 rats were divided into normal control group(the rats didn't receive any treatment,n=15),osteoporosis group(the rats were ovariectomized,n=15)and osteoporosis treatment group (the ovariectomized rats were injected with estrogen through caudal vein,n=15).The changes of serum collagenⅠ(Col Ⅰ),alkaline phosphatase(ALP)and osteocalcin(OCN)of the rats in various groups were observed. Three months after feeding,the femoral shaft of the rats in various groups were taken for pathological section.The gene expression levels of PERK,ATF4,Runx2,osterix,RANKL and OPG in bone tissue of the rats in various groups were detected by RT-PCR;the protein expression levels of PERK,ATF4,Runx2,osterix,RANKL and OPG were detected by Western blotting method.Results:Compared with control group,the levels of serum Col Ⅰ,ALP and OCN in the rats in osteoporosis group were significantly decreased(P<0.05 or P<0.01);compared with osteoporosis group,the levels of serum ColⅠ,ALP and OCN of the rats in osteoporosis treatment group were significantly increased(P<0.01).Compared with control group,the gene expression levels of PERK, ATF4,Runx2 and osterix in bone tissue of the rats in osteoporosis group were significantly decreased(P<0.01), and the gene expression level of RANKL was increased(P<0.01);compared with osteoporosis group,the gene expression levels of PERK,ATF4 Runx2 and osterix in bone tissue of the rats in osteoporosis treatment group were significantly increased(P<0.01),and the gene expression level of RANKL was significantly decreased(P<0.01).Compared with control group,the protein expression levels of PERK,Runx2 and osterix in bone tissue of the rats in osteoporosis group were significantly decreased(P<0.05 or P<0.01),and the protein expression level of RANKL were increased(P<0.05 or P<0.01);compared with osteoporosis group,the protein expression levels of PERK,Runx2 and osterix in bone tissue of the rats in osteoporosis treatment group were significantly increased(P<0.05 or P<0.01),and the protein expression level of RANKL was significantly decreased(P<0.01).The HE staining results showed that compared with control group,the bone resorption pits in bone tissue of the rats in osteoporosis group became large with the increased bone absorption,which caused bone loss;compared with osteoporosis group,the resorption in bone tissue of the rats in osteoporosis treatment group was decreased,and the bone structure returned to normal.Conclusion:After the female rats are ovariectomized and injected with estrogen,the expression trends of PERK and osteoblast transcription factors Runx2 and osterix are consistent,in contrast with the osteoclast transcription factor RANKL expression,suggesting that the osteoblast function is reduced and it is related to the decreased expression of PERK in PMOP onset.

ABSTRACT

Objective To investigate the diagnostic value of quantitative detection of α-synuclein and DJ-1 protein in saliva for Parkinson Disease. Methods Twenty seven patients diagnosed with primary Parkinson's disease and 27 healthy controls were studied.The clinical data of all subjects were collected.Each participant received a disease evaluation including Hohn-Yahr stage, unified Parkinson Disease Rating Scale (UPDRS)-Ⅱ / Ⅲ, 12 Item odor identification test from Sniffin'Sticks (SS-12), Montreal cognitive assessment (MoCA), Mini Mental State Examination (MMSE).α-syn and DJ-1 protein in saliva were examined by using enzyme linked immunosorbent assay (ELISA). The statistical analysis was used to test the difference in these two protein levels between patient and control groups and the correlation with age, gender and course of disease. Results There were significant changes in mean concentration of salivary α-syn (1269.02±16.09 pg/mL、1350.51±25.79 pg/mL,P=0.010) and DJ-1 protein (6.07±3.23 ng/mL、8.43±4.33 ng/mL,P=0.027) between patient and control groups. The sensitivity of α-syn and DJ-1 protein levels in PD diagnosis was 55.56% and 77.8%,and the specificity was 89.19% and 55.6%.The area under the ROC curve in finding the PD of α-syn and DJ-1 was 0.671 and 0.649, respectively. In Parkinson disease group, age, gender, UPDRS-Ⅱ / Ⅲ, Hohn-Yahr stage, SS-12, MMSE and MoCA of Parkinson's disease group were not related to the concentration of α-syn and DJ-1 protein in saliva (P>0.05). Conclusion The detection of α-syn and DJ-1 protein levels in saliva may be an auxiliary tool for diagnosis of PD.

ABSTRACT

Objective To investigate the risk factors of hyperbilirubinemia in late preterm infants. Methods The clinical data of 815 late preterm infants (449 males and 366 females) from 25 hospitals in Beijing were collected from October 2015 to April 2016, including 340 cases(41.7%) with hyperbilirubinemia (hyperbilirubinemia group), and 475 cases without hyperbilirubinemia (control group). The clinical data of two groups were compared, and the maternal factors influencing hyperbilirubinemia in late preterm infants were analyzed with logistic regression. Results There were no significant differences in gender ratio (M:F 1.39 vs. 1.12, t=1.811,P=0.172)and birth weight[(2502.6±439.6)g vs. (2470.2±402.9)g,χ2=2.330,P=0.127)]between two groups. The incidence rates of hyperbilirubinemia in infants of 34 wks, 35 wks and 36 wks of gestational age were 22.9%(87/174), 35%(119/300) and 42.1%(143/341) respectively (χ2=1.218,P=0.544). The multivariate logistic regression analysis indicated that the maternal age(OR=1.044,95% CI:1.010-1.080,P=0.011)was independent risk factor and multiple births(OR=1.365,95%CI:0.989-1.883,P=0.048), premature rupture of membranes(OR=2.350,95% CI:1.440-3.833,P=0.001), cesarean section(OR=1.540,95%CI:0.588-4.031,P=0.014)were risk factors for hyperbilirubinemia in late preterm infants. Conclusions The incidence of hyperbilirubinemia in late preterm infants is relatively high. Maternal age, multiple births, premature rupture of membranes and cesarean section are risk maternal factors related to hyperbilirubinemia in late preterm infants.

ABSTRACT

Objective To explore the incidence of olfactory dysfunction in patients with Parkinson disease and the characteristic as well as its possible influencing factors. Methods The SS-12 was used to evaluate the olfactory function of 106 patients with Parkinson's disease and 110 healthy volunteers. The data was then compared between the two groups to investigate the correlation of olfactory function with age, gender, education, smoking, disease duration, Hohn-Yahr stage, UPDRSⅢscores, the dosage of levodopao and olfactory scores. Results Mean identification scores were significantly lower in patients(5.97 ± 2.27)than in controls(8.04 ± 2.00)(t=7.108, P=7.108). Parkinson's disease group did worse than the control group in identifying some odors including peppermint, bananas,liquorice,coffee,pineap?ple,rose and fish (P0.05). Conclusion Olfactory dysfunction occurs in Parkinson disease with an hign incidence rate. Olfactory function has nothing to do with disease duration, Hohn-Yahr stage, UPDRSⅢscores and the dosage of levodopa in Parkinson disease.

ABSTRACT

Objective To investigate the effect of alprostadil injection on serum tumor necrosis factor ( TNF-α) ,β2-microglobulin (β2-MG) and soluble interleukin 2 receptor (sIL-2R) levels in adjunctive treatment of patients of severe hepatitis with liver and kidney syndrome.Methods A total of 60 patients of severe hepatitis with liver and kidney syndrome were collected and randomly divided into experimental group and control group with 30 cases in each group.The two groups were treated by conventional therapy, patients in the control group were treated by continuous renal replacement therapy, patients in the experimental group were treated on the basis of the control group with alprostadil injection in adjuvant therapy for 3 weeks.The serum biochemistry and liver and kidney function and clinical curative effect were detected.Results Compared with the control group, the serum TNF-α, β2-MG and sIL-2R levels of the experimental group were lower (P<0.05); alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirnbin (TBiL) levels were lower (P<0.05), albumin (Alb) level and prothrombin time activity (PTA) were higher (P<0.05), serum creatinine (Scr), urea nitrogen (BUN), CysC and 24h urine protein were lower (P<0.05), 24h urine volume was higher (P<0.05); efficacy in experimental group was better than control group (Z=-2.321,P=0.020).Conclusion Alprostadil injection in adjunctive treatment of severe hepatitis with liver and kidney syndrome patients has significant effect and high safety, could significantly reduce the serum TNF-α, β2-MG and sIL-2R levels.

ABSTRACT

Objective To investigate the possible effect of ginsenoside Rg1 and oligo Aβ1-42 on PKA/CREB pathway.Methods The damage was induced by oligomeric Aβ1-42 in primary cortical neuron.Neurons were incubated with or without glutamate,or incubated in Aβ,or pre-incubated in Rg1 and then co-incubated in Aβ.The proteins of p-CREB,t-CREB,PKA Ⅱ α and BDNF were detected by Western blot.Results After the treatment with Oligo Aβ1-42 for 2 h,the p-CREB/t-CREB level induced by glutamate was obviously lower (P< 0.001).However,in neurons pre incubatedwith 2.5,5.0,10.0 μmol/L of ginsenoside Rg1 and then co-incubated with 5μmol/L of oligo Aβ1-42,the p-CREB/t-CREB induced by glutamate was significantly increased as compared with that of Aβ1-42 group (P<0.05).Upon Aβ1-42 exposure for 2 h,cortical neurons showed a statistically significant increase in PKA Ⅱ α as compared to the control group (P < 0.001).Pre-treatmentwith varying doses of ginsenoside Rg1 (2.5,5,10μmol/L) showed a decrease in PKA Ⅱ α as compared to neurons treated with Aβ1-42 alone for 2 h (P<0.001).Furthermore,BDNF level significantly increased in Rgl-pretreated cells as compared to cells treated with Aβ1-42 alone for 24h (P<0.05).Conclusions Ginsenoside Rg1 attenuates the oligo Aβ142 inhibition of PKA/CREB pathway.

ABSTRACT

Objective To study the postpartum pelvic floor rehabilitation on the improvement of pelvic floor electrical physiological indexes and the prevention of female pelvic floor dysfunction in China. Methods A multicenter prospective randomized controlled study was carried out. From October 2011, postpartum women in five provinces were randomly assigned into treatment group and control group. The women in treatment group received electrical stimulation and biofeedback treatment. The women in control group performed pelvic floor muscle exercise at home. When 6 months and 12 months after delivery, comparing two groups of patients with pelvic floor electrical physiological indexes and pelvic organ prolapse quantitation measurements (POP-Q), to evaluate the effect of postpartum pelvic floor rehabilitation on the prevention of pelvic floor dysfunction. Pelvic floor impact questionnaire short form (PFIQ-7) and pelvic organ prolapse/incontinence sexual questionnaire-12 (PISQ-12) were used to evaluate the influence on quality of life and sexual life. Results Until June 2013, 324 women were participated, 124 in control group, 200 in treatment group. According to the baseline results, there was statistical significance in the results of pelvic floor electrical physiological indexes between the treatment and control groups in postpartum 6 months and 12 months; the proportion above level Ⅲ of type Ⅰ and type Ⅱ muscle fibers strength in the treatment group, it was from 41.5% (83/200) and 40.5% (81/200) to 76.3% (145/190) and 79.5% (151/190) in postpartum 6 weeks and postpartum 6 months, increased to 80.6%(58/72) and 80.6%(58/72) in postpartum 12 months, improved significantly comparing with the control group (P0.05). There was no significant difference in the questionnaires in quality of life and quality of sexual life (P>0.05). Conclusion Neuromuscular electrical stimulation and biofeedback therapy in the early postpartum period could obviously improve pelvic floor electrical physiological indexes, and is beneficial to prevent the pelvic floor dysfunction.
