ABSTRACT
In different stages of the course of intracerebral hemorrhage, various interleukins (ILs) play different roles. IL-1α and IL-1β can aggravate perihematomal edema (PHE) by affecting the integrity of the blood-brain barrier in the early stage of intracerebral hemorrhage. IL-6 and IL-8 play a key role in the whole course of intracerebral hemorrhage and affect the severity of PHE by inducing inflammation. IL-3 promotes the development of PHE by promoting microglia activation. IL-11 and IL-17A can be used to assess disease severity and as predictors of PHE, but they do not play a decisive role in the development of intracerebral hemorrhage. IL-4 and IL-10 have certain improvement effects on the development of PHE and the outcomes after cerebral hemorrhage.
ABSTRACT
In recent years， with the change in life style， social environment， and national childbearing policy， the proportion of high-risk pregnant women has increased significantly， triggering the spectrum of obstetric diseases to constantly change， which has brought new challenges to the diagnosis and treatment of obstetrics. Traditional Chinese medicine （TCM） has been proved effective in dealing with a variety of obstetric diseases， and various treatment methods are available， which can serve as alternative means for solving refractory obstetric diseases. However， most obstetric clinicians are currently less aware of the therapeutic effects of TCM， which has significantly hindered its participation in clinical treatment. Therefore， the China Association of Chinese Medicine （CACM） organized the outstanding young obstetricians of TCM and western medicine to discuss 15 obstetric diseases responding specifically to TCM or integrated TCM and western medicine， including hyperemesis gravidarum， threatened abortion， ectopic gestation， cough during pregnancy， pregnancy-induced hypertension syndrome， maternal-fetal ABO incompatibility， postpartum hypogalactia， residual pregnancy tissue in uterine cavity， puerperal infection， pantalgia after childbirth， hematoma/undesirable healing after caesarean section， postpartum urinary retention， ileus after cesarean section， pelvic floor dysfunction， and postnatal depression. The suggestions for their treatment with TCM or integrated TCM and western medicine were also proposed， aiming to provide patients with effective and personalized treatments in clinical practice and improve the diagnosis and treatment effects of obstetric diseases， thus benefiting the public. At the same time， more obstetrical clinicians are expected to understand the therapeutic effects and advantages of TCM and draw on the strengths of both TCM and western， thereby promoting the establishment of an obstetric diagnosis and treatment system with Chinese characteristics.
ABSTRACT
Objectives To explore the relationship between the extension force deficiency of the lower extremity and fall risks among the senior female,so as to reveal the potential factors contributing to fall.Methods Forty community-dwelling senior females aged 65 and older were assigned to the group of fallers or non-fallers according to their reported fall history and measured fall risk index (FRI).Extension force of the lower extremity was measured through 3-consecutive fast squats on a force platform.The time for 3m-time up and going (TUG),as well as static and dynamic balance were also measured.Results Compared to the non-fallers,the fallers showed lower peak extension force per body weight (PEF/BW) of the left leg and larger asymmetry of the peak extension force per body weight between the two legs in squats.Correlation analysis showed that FRI had a strong negative relation with PEF/BW of the left leg and a strong positive relation with extension force asymmetry/body weight.Also time for 3m-TUG was positively related to all the force variables standardized by the body weight,especially for the left leg.However,the analysis failed to find a relationship between the velocity of the center of pressure (COP) sway on static balance and any force variables.In addition,PEF/BW of the left leg decreased and force asymmetry/body weight between the two legs increased with aging.Conclusion Extension force measurement in squat is an effective way to assess the muscle strength deficiency related to the increased fall risk.The extension force of the lower extremity to support the body weight in squat had a strong relation to the function decline in the dynamic balance,which contributes greatly to fall risk.The extensive force asymmetry in squat between the two legs is another important fall risk factor for the senior females.
ABSTRACT
BACKGROUND:In recent years, the application of stem cel s to treat autoimmune diseases has become a hot spot. But, studies on umbilical cord blood mesenchymal stem cel s transplantation for the treatment of polymyositis/dermatomyositis are rarely reported. OBJECTIVE:To explore the immunologic mechanism of Th cytokines on the occurrence and development of polymyositis/dermatomyositis by observing the changes in serum interferon-γ, interleukin-4 and interleukin-17 in patients after umbilical cord blood mesenchymal stem cel s transplantation. METHODS:Eighty-one polymyositis/dermatomyositis patients were selected and divided into conventional therapy group (n=44) undergoing glucocorticoid and immunosuppressants therapy and cel transplantation group (n=37) undergoing intravenous infusion of umbilical cord blood mesenchymal stem cel s at a density of (3.5-5.2 )×107 . Dosing regimen was same in the two groups. After fol ow-up of 1, 3, 6 months, the changes of creatine kinase and myodynamia were evaluated;after fol ow-up of 3 and 6 months, lung imaging was evaluated;in the cel transplantation group, interferon-γ, interleukin-4 and interleukin-17 levels were detected before treatment and at 3 and 6 months after treatment. RESULTS AND CONCLUSION:At 1, 3, 6 months after treatment, the creatine kinase level was significantly decreased, and the muscle force grade was significantly increased in both groups (both P0.05). These findings indicate umbilical cord blood mesenchymal stem cel s transplantation combined with glucocorticoid and immunosuppressants therapy can adjust immune network effects and improve the immune tolerance in polymyositis/dermatomyositis patients, which is safe and effective.
ABSTRACT
<p><b>OBJECTIVE</b>To determine the effects of bisphenol-A (BPA) on blastocyst development and implantation.</p><p><b>METHODS</b>According to completely randomized grouping method, 90 pregnant mice were divided into 100, 300, and 600 mg/(kg·d)BPA groups and control group. BPA-treated pregnant mice were orally administered with BPA at concentrations of 100, 300 and 600 mg/(kg·d) from day 0.5 to day 3.5 of their pregnancy. Blastocyst implantation and development were studied.</p><p><b>RESULTS</b>In the 300 mg/(kg·d) BPA group, the number of implantation sites and implantation rate were significantly decreased. In the 600 mg/(kg·d) group, no implantation sites were observed among pregnant mice and BPA inhibited embryo implantation. Blastocyst development on day 4 was examined, and findings showed that the development rate and total numbers of blastocysts in BPA treatment groups had no significant difference from the control group. However, BPA at 300 and 600 mg/(kg·d) significantly reduced blastocyst hatching rate and dramatically increased the number of blastocyst apoptotic cells when compared with those in the control group.</p><p><b>CONCLUSION</b>BPA at a high concentration damages the blastocyst development before implantation and inhibits embryo implantation.</p>

<p><b>OBJECTIVE</b>To investigate the balance function of the patients with unilateral vestibular hypofunction (UVH) by timed balance tests and static posturography (SPG).</p><p><b>METHODS</b>Sixty-five subjects with UVH and 92 healthy subjects were taken the timed balance tests under differential stance including (1) standard Romberg test, (2) feet apart stance test, (3) tandem and (4) unilateral standing tests with eyes open and eyes closed. The average timing that subjects kept balance before falling in each standing conditions was recorded by stopwatch as the timed result. The body sway velocity during the test (1) and (2) were also recorded by the SPG.</p><p><b>RESULTS</b>The timed results of the tandem and unilateral standing with eyes open and eyes closed in the UVH group were decreased (P < 0.001) compared with the control group. The body sway velocity of the standard Romberg test and foot apart stance with eyes open was not different between the UVH group and control group (P-value was 0.118 and 0.110 for the two tests respectively), and the difference was significant in the eyes closed condition (P < 0.001). For the two groups, the body sway velocity of foot apart standing was decreased than that of the standard Romberg test with eyes open and eyes closed (P < 0.05 or P < 0.001). Significant correlations were not found between the timed results and sway velocity results in both two groups respectively (P > 0.05).</p><p><b>CONCLUSIONS</b>According to clinical assessment of balance function in UVH, the tandem and unilateral stance test could provide the additional information about the upright stance to the SPG measurement. The effect of foot position on the results of SPG should been considered in clinic.</p>
