Objective To investigate the relation between the cellular immune function and unexplained recurrent spontaneous abortion(URSA) and the mechanism of active immunotherapy on URSA patients.Methods The flow cytometry(FCM) was used to detect CD3+ ,CD4+ ,CD8+ T lymphocyte and CD16+CD56+ natural killer(NK) cell subsets and the ratio of CD4+/CD8+ of peripheral blood(PBL).112 cases with URSA(76 cases treated with active immunotherapy) and 30 cases of normal fertiled(NF) women were studied.The percentages of T lymphocyte and NK cell subsets before and after therapy were compared among 76 cases wtih URSA treated by active immunotherapy.The rate of next successful pregnancy of URSA patients treated with and without active immunotherapy was compared.Results The percentages of CD3+ and CD16+CD56+ cell subsets as well as the ratio of CD4+/CD8+ of the URSA patients were significantly higher than those of NF cases(P <0.05).After active immunotherapy,the percentages of CD3+ and CD56+CD16+ cell subsets as well as the ratio of CD4+/CD8+ of URSA cases were significantly decreased(P <0.05 ).The rate of next successful pregnancy of URSA cases with and without active immunotherapy were 88.2% and 31.2% respectively,the difference was significant(P< 0.05).Conclusion The changes in the percentages of T lympyocyte and NK cell subsets have something to do with URSA.Active immunotherapy can effectively regulate the cellular immune function and increase the rate of next successful pregnancy of URSA patients.

OBJECTIVEOver the last few decades, diabetic cardiomyopathy has been identified as a significant contributor in cardiac morbidity. However, the mechanisms of diabetic cardiomyopathy have not been clarified.

METHODSIn the present study, a diabetic rat model was induced by the intraperitoneal injection of streptozotocin. The myocardial CD147 expression and extent of glycosylation, as well as thematrixmetalloproteinases(MMPs) expression and activity, were observed in the diabetic and synchronous rats.

RESULTSThe results showed that CD147 located on sarcolemma of cardiomyocytes. The myocardial CD147 expression and glycosylation were significantly increased in the diabetic rats as compared with the control. Expression of MMP-2 protein, MMP-2 and MMP-9 activity were also increased in left ventricular myocardium in the diabetic rats. Tamoxifen only inhibited the enhanced expression of myocardial CD147 in the diabetic rats, but not in synchronous control rats. Tamoxifen inhibited glycosylation of myocardial CD147 in both diabetic and control rats. The inhibition of tamoxifen on CD147 glycosylation was stronger than on the expression in the myocardium. The extent of myocardial CD147glycosylation was positively related toMMP-2 and MMP-9 activity. Tamoxifen induced an inhibition of myocardial MMP-2 and MMP-9 activity in the control and diabetic rats.

CONCLUSIONThese results indicate that myocardial CD147 expression, especially the extent of glycosylation, regulates MMP-2 and MMP-9 activity, then accelerates cardiac pathological remodeling inducing diabetic cardiomyopathy. Tamoxifen inhibits myocardial CD147 glycosylation and further depress the activity of MMPs. Therefore, tamoxifen may protect the diabetic rats against diabetic myocardium.

OBJECTIVETo study the clinical feature of a Chinese family with muscle-eye-brain disease (MEB) and the mutation of protein O-linked-mannose beta-1, 2-N-acetylglucosaminyltransferase 1 gene (POMGNT1).

METHODSClinical data of the proband and his family members were collected. Genomic DNA from the patient and his parents was extracted using standard procedures from the peripheral blood leukocytes. Polymerase chain reaction and DNA direct sequencing were employed to analyze all of the exons to determine the mutation, and the relationship between genotype and phenotype was analyzed.

RESULTSThe proband was diagnosed as floppy baby, presented with delayed psychomotor development and myopathic face. His serum creatine kinase (CK) level elevated moderately and brain MRI showed cerebral and cerebellar gyrus abnormalities with white matter signal intensity changes, cerebellar cysts and cerebellar and brain stem hypoplasia, consistent with congenital muscular dystrophy with eye brain disorder. Further test with DNA detected a compound heterozygous mutation of c.1896 1 G to C before exon 22 which may induce splicing error, and missense mutation c.1319T to G, p.L440R in exon 16. Both parents had a heterozygous mutation at the mutation sites.

CONCLUSIONAccording to our study, the family is diagnosed as MEB. The proband carried compound heterozygous mutations in the POMGNT1 gene, and his parents are heterozygous carriers, which is consistent with autosomal recessive inheritance. The child is definitely diagnosed as having muscle eye brain disease.

OBJECTIVETo evaluate the predictive value of Holter ECG recordings for patients with moderate-severe obstructive sleep apnea and hypopnea syndrome (OSAHS).

METHODSHolter recordings was performed in 76 patients who were diagnosed OSAHS by polysomnography (PSG) within one month from Jan. 2008 to July 2009 in our hospital. Twenty-eight patients were identified as mild OSAHS (AHI < or = 20) and forty-eight patients were moderate-to-severe OSAHS (AHI > 20). The indexes of heart rate variability (HRV), total scores of thirteen sleep apnea risk indexes of Holter recordings and BMI were analyzed by bivariate Logistic regression analysis.

RESULTSClinical features (eg. Gender, age, complicated with hypertension, coronary heart disease, diabetes mellitus, hyperglycemia, and taken beta-blocker), total scores, the sum of thirteen sleep apnea risk scores collected by Holter recordings (5.64 + or - 2.33 vs. 6.42 + or - 2.22, respectively, P > 0.05) were similar between patients with mild OSAHS and moderate-to-severity OSAHS. VLF/Total Power > 70%, the difference of daytime/nighttime LF Power < -70 and BMI were independent predictors of moderate-to-severe OSAHS with OR 3.98 (1.087 - 14.596), 3.69 (1.106 - 12.285) and 1.28 (1.062 - 1.544), respectively (all P < 0.05).

CONCLUSIONSVLF/Total Power and the difference of daytime/nighttime LF Power and BMI could be used as screening parameters to recognize patients with moderate-to-severe OSAHS.

OBJECTIVETo study the clinical effectiveness of implanting miniscrew serving as anchorage instead of molars in treating maxillary dental arch crowding and protrusive patients mandibular molars complete missing.

METHODSEight adult patients aged from 22 to 38, whose maxillary dental arch were crowding and protrusion, with mandibular molars missing were chosed. At the missing side, a miniscrew was implanted on the buccal surface, 11-13 mm away from the distal end of the second premolar. After implanting, a self-made miniscrew traction cap was attached to its supergingival section by keyway retention. Premolars and anterior teeth were tracted in turn to distal end. Intermaxillary traction II was made necessarily on the traction cap.

RESULTSSuccessful results were acquired after treating together with normal overbite, overjet and right occlusion relation. It took 24 months in the longest course, 15 months in the shortest course and 20.8 months on average.

CONCLUSIONThe implanting miniscrew anchorages could be used in maxillary dental arch crowding and protrusive patients with single molars complete missing.

Objective To investigate the effect of hand robot-assisted training based on motor imagery on upper limb function of stroke patients.Methods From November, 2016 to May, 2018, 55 hemiplegic patients with upper limb dysfunction were randomly assigned to control group (n = 25) and experimental group (n = 30). The control group received routine hand motor training, while the experimental group received hand robot-assisted training, for four weeks. They were assessed with simplified Fugl-Meyer Assessment-Upper Extremity (FMA-UE), Wolf Motor Function Test (WMFT) and Modified Barthel Index (MBI) before treatment (t0), one week of treatment (t1), immediately after treatment (t2) and 2 months after treatment (t3).Results The score of WMFT improved in the experimental group at t1 (P ＜ 0.05), with no significant difference between groups (Z =-0.901, P＞ 0.05). The scores of FMA, WMFT and MBI improved in both groups at t2 and t3 (P ＜ 0.05), and the scores of FMA and MBI improved more in the experimental group than in the control group (Z＞-2.073, t＞ 2.034, P ＜ 0.05).Conclusion Hand robot-assisted training based on motor imagery can promote recovery of upper limb function in stroke patients more effective than routine hand function training.

In vertebrate visual system, retina is the first stage for visual information processing. Retinal ganglion cells are the only output neurons of the retina, and their firing activities are dependent on visual stimuli. Retinal ganglion cells can effectively encode visual information via various manners, such as firing rate, temporal structure of spike trains, and concerted activity, etc. Adaptation is one of the basic characteristics of the nervous system, which enables retinal neurons to encode stimuli under a wide variety of natural conditions with limited range in their output. This article reviews the recent studies focused on the coding properties and adaptation of retinal ganglion cells. Relevant issues about dynamical adjustment of coding strategies of retinal ganglion cells in response to different visual stimulation, as well as physiological property and function of adaptation are discussed.

BACKGROUNDRapid eye movement (REM) sleep behavior disorder (RBD) may be a risk factor for cognitive impairment in patients with Parkinson's disease (PD). However, little is known regarding the relation between the severity of RBD and the different domains of cognitive impairment. The aim of this study was: (1) to investigate the domains of cognitive impairment in patients with PD and RBD, and (2) to explore risk factors for PD-mild cognitive impairment (PD-MCI) and the relationship between RBD severity and impairment in different cognitive domains in PD.

METHODSThe participants were grouped as follows: PD without RBD (PD-RBD; n = 42), PD with RBD (PD + RBD; n = 32), idiopathic RBD (iRBD; n = 15), and healthy controls (HCs; n = 36). All participants completed a battery of neuropsychological assessment of attention and working memory, executive function, language, memory, and visuospatial function. The information of basic demographics, diseases and medication history, and motor and nonmotor manifestations was obtained and compared between PD-RBD and PD + RBD groups. Particular attention was paid to the severity of RBD assessed by the RBD Questionnaire-Hong Kong (RBDQ-HK) and the RBD Screening Questionnaire (RBDSQ), then we further examined associations between the severity of RBD symptoms and cognitive levels via correlation analysis.

RESULTSCompared to PD-RBD subjects, PD + RBD patients were more likely to have olfactory dysfunction and their Epworth Sleepiness Scale scores were higher (P < 0.05). During neuropsychological testing, PD + RBD patients performed worse than PD-RBD patients, including delayed memory function, especially. The MCI rates were 33%, 63%, 33%, and 8% for PD-RBD, PD + RBD, iRBD, and HC groups, respectively. RBD was an important factor for the PD-MCI variance (odds ratio = 5.204, P = 0.018). During correlation analysis, higher RBDSQ and RBDQ-HK scores were significantly associated with poorer performance on the Trail Making Test-B (errors) and Auditory Verbal Learning Test (delayed recall) and higher RBD-HK scores were also associated with Rey-Osterrieth complex figure (copy) results.

CONCLUSIONSWhen PD-RBD and PD + RBD patients have equivalent motor symptoms, PD + RBD patients still have more olfactory dysfunction and worse daytime somnolence. RBD is an important risk factor for MCI, including delayed memory. Deficits in executive function, verbal delayed memory, and visuospatial function were consistently associated with more severe RBD symptoms.

BACKGROUNDThere is a paucity of studies investigating the clinical and biochemical characteristics of pain in chronic heart failure (CHF) patients. This study aimed to determine the clinical and biochemical characteristics and outcomes in Chinese patients with CHF and symptoms of pain.

METHODSSociodemographics, serum levels of creatinine, NT-proBNP, high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-10, and two-dimensional echocardiographic left ventricular ejection fraction (LVEF) were determined in 305 patients with CHF. A questionnaire packet including the Brief Pain Inventory (BPI) and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used to assess the degree of pain rated on a 0 - 10 scale and the quality of life (QOL). A six-minute walking test was performed during routine clinic visits. Major adverse cardiac events (MACE) were recorded; including all-cause or cardiac mortality and rehospitalization because of myocardial infarction, worsening heart failure or stroke at follow-up.

RESULTSPain occurred in 25.6% of CHF patients, and was more common when the New York Heart Association (NYHA) functional class was worse. More patients with pain were female in gender, and had more co-morbidities, lower LVEF, and shorter distance during the 6-minute walking test. Despite similar serum levels of creatinine, N-terminal prohormone of brain natriuretic peptide (NT-proBNP), IL-6 and IL-10, the TNF-α levels were higher and MLHFQ scores were greater in CHF patients with pain. At follow-up, CHF patients with moderate to severe pain (≥ 4 scale) had higher rates of all-cause and cardiac mortality and rehospitalization because of myocardial infarction, worsening heart failure or stroke. Multivariate regression analysis revealed that the presence of pain was an independent risk factor for MACE and reduced QOL in CHF patients.

CONCLUSIONSPain occurs in all stages of the CHF trajectory, and its incidence increases as clinical functional status is worsened. The presence of pain exerts a negative impact on clinical outcome and QOL in patients with CHF.
