Objective To develop a prediction model for functional gain in the activities of daily living (ADL) after stroke rehabilitation. Methods Logistic regression was applied to 896 patient records from two hospitals. Functional gains in ADL were measured using a modified Barthel index (MBI). Results Five parameters were screened in the logistic regression model. The equation was: Logit( P/Y =1)=6.259+1.048 ( first onset to admission interval)+1.242(MBI score at admission)+0.300(number of comorbidities)+1.095(retired cadre dummy)+ 0.906(worker dummy) + 1.384 (professional dummy). This formulation accounted for about 78% of the variance in the data. Conclusions MBI score at admission, the interval between first onset and admission, comorbidities, job status and occupation are the main factors predicting functional ADL gains after stroke. The model can be used to predict outcomes for individual stroke patients at admission to rehabilitation.

Objective To study effects of different degree of hypothyroidism in severe preeclampsia (S-PE) pregnant women on renal function and the correlation between them.Methods 46 S-PE patients with subclinical hypothyroidism (SCH) registered for treatment in the Shengjing Hospital of China Medical University from May 2011 to March 2013 were selected into SCH group,and 23 S-PE with overt hypothyroidism (OH) were selected into OH group,and 109 S-PE with normal thyroid stimulating hormone (TSH) levels were selected into simple group.Thyroid hormone and kidney function tests were analyzed in pregnant women with S-PE.We made an analysis of the relative risk of the detection rate of abnormal renal function and also the relationship between the levels of thyroid hormone and serum uric acid,serum urea and creatinine in patients with S-PE.Results (1) In SCH group serum TSH was (6.1±3.2) mU/L,free triiodothyronine (FT3) was (4.0±0.6) pmol/L,free thyroxine (FT4) was (11.8± 1.5) pmol/L; in OH group serum TSH was (5.2± 1.3) mU/L,FT3 was (3.7±0.6) pmol/L,FT4 was (9.3±0.5) pmol/L; in simple S-PE group serum TSH was (1.9±0.8) mU/L,FT3 was (4.0±0.8) pmol/L and FT4 was (11.9±1.9) pmol/L.TSH in SCH group was significantly higher than that in simple S-PE group (P＞0.01),the difference of in SCH and OH group were not statistically significant (P＞0.05).The difference of FT3 in three groups were not statistically significant (P＜0.05) ;FT4 in OH group was significantly lower than thoes in SCH and simple groups (P＜0.05).(2)Serum uric acid,creatinine and urea levels in OH group was (436± 114),(75± 15) μmol/L and (6±3)mmol/L,in simple S-PE group they were (378± 114),(65 ±22) μmol/L and (5±3) mmol/L.In comparison,the differences was statistically significant(P＜0.05).The differences were not statistically significant in SCH and OH groups (P＞0.05).(3)The abnormal detection rate of uric acid was significantly higher in SCH than that in OH group [46％ (21/46) versus 22％ (5/23),OR=3.0,P＜0.05].The comparison of remaining index has no statistical significance(P＞0.05).(4)In SCH group there was a significant inverse correlation of serum FT3 with serum urea levels,serum creatinine and serum uric acid (r=-0.32,-0.58,-0.35,P＜0.05).There was not a correlation of serum TSH,FT4 with indicators of renal function (P＞0.05).In OH group there was a negative correlation between FT3 and serum creatinine concentrations (r=-0.40,P＜0.05).In OH group there was not a correlation of FT3 with serum uric acid and urea (P＞0.05).There was a positive correlation between TSH and serum creatinine in simple S-PE group (r=0.20,P=0.04).There was not a correlation between TSH and serum urea(r=0.04,P=0.65),and serum uric acid (r=0.12,P=0.20).Conclusions There was effect of different hypothyrosis state in pre-eclampsia patients on renal function.Serum uric acid,urea and creatinine concentrations in S-PE pregnant women with OH were significantly higher than those in simple S-PE group with normal TSH.There was a negative correlation between FT3 and serum creatinine in S-PE.Hence the thyroid function should be regularly monitored in S-PE patients to find damage of renal function and management hypothyrosis.

Objective To study thyroid hormone changes in women with pre-eclampsia patients,the characteristics of thyroid disease and its relationship with pre-eclampsia.Methods From May 2011 to December 2012 171 patients with pre-eclampsia who delivered in Shengjing Hospital of China Medical University were recruited as prc-eclampsia(PE) group,among which 114 cases were defined as early onset pre-eclampsia (EP) group and 57 cases were defined as late onset pre-eclampsia (LP) group.And 171 healthy women with same age and same stage of pregnancy were selected as the control group.Their blood pressures were normal and they had no obstetrical complications.Serum thyrotropin (TSH),free triiodothyronine (FT3) and free thyroxine (FT4) levels were determined by solid-phase chemiluminescent enzyme immunoassay method (CMIA).Thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TGAb) were measured by electro-chemiluminescent assay (ECLIA).The positive rate was calculated (TPOAb ＞ 5.6 U/L,TGAb ＞ 4.1 U/L were defined as positive result).The relationship between TSH,FT3,FT4 level and blood pressure was analyzed in women with pre-eclampsia.Results (1) The median values of TSH,FT4 and FT3 in PE group were 3.4 mU/L,(12.0 ± 3.0) pmol/L and(3.9 ± 0.9) pmol/L.In the control group,they were 1.9 mU/L,(13.4 ± 2.4) and (5.0 ± 1.3) pmol/L.There were statistically significant differences between the two groups(P ＜ 0.01).In EP group,the median values of TSH,FT4 and FT3 were 3.3 mU/L,(12.1 ± 3.4) pmol/L and (3.8 ± 0.9) pmol/L.The differences between EP group and the control group were statistically significant (P ＜ 0.01).In LP group,the median values of TSH,FT4 and FT3 were 3.4 mU/L,(11.9 ± 3.1) pmol/L and (3.9 ± 1.0) pmol/L.There were statistically significant differences compared to the control group(P ＜0.01).While there was no difference between EP group and LP group (P ＞ 0.05).(2) The positive rate of TPOAb and TGAb in PE group were 15.2％ (26/171)and 21.6％ (37/171),and were 12.3％ (21/171) and 14.6％ (25/171) in the control group.There was statistically significant difference in the TGAb positive rate (P ＜ 0.01),but the difference in TPOAb positive rate was not statistically different(P ＞0.05).The TPOAb positive rates in EP group and LP group were 12.3 ％ (14/114) and 21.1％ (12/57),respectively,with no statistically significant difference (P ＞ 0.05).And the positive rates of TGAb in EP group and LP group were 21.9％ (25/114)and 21.1％ (12/57),respectively,with no statistically significant difference(P ＞ 0.05).The positive rate of TPOAb in LP group and in the control group had statistically significant difference(P ＜0.01).(3) The morbidity of thyroid disease in PE group and in the control group were 47.4％ (81/171) and 16.4％ (28/171),with statistically significant difference (P ＜ 0.01).(4) The morbidity of subclinical hypothyroidism or hypothyroidism in PE group and in the control group were 45.0％ (77/171) and 16.4％ (28/171),with statistically significant difference(P ＜0.01).(5) The morbidity of subclinical hyperthyroidism in PE group and in the control group were 2.3 ％ (4/171) and 1.8 ％ (3/171),with no statistically significant difference (P＞0.05).(6) In PE group,women with TSH level of 0.3-3.3 mU/L had systolic pressure of(170 ± 21)mmHg (1mmHg =0.133 kPa)and diastolic pressure of(112 ± 15) mmHg; women with TSH ＞ 3.3 mU/L had systolic pressure of(166 ± 21)mmHg and diastolic pressure of(109 ± 13)mmHg.There was no statistically significant difference(P ＞ 0.05).But the diastolic pressure in EP group and LP group had statistically significant difference(P ＜ 0.01).In PE group,no correlation was found among TSH,FT4 levels and systolic pressure,diastolic pressure(P ＞ 0.05).FT3 level was negatively correlated to diastolic pressure (r =-0.172,P =0.023).Conclusions It is common that pre-eclampsia is complicated with thyroid dysfunction,mainly subclinical hypothyroidism.Thus it is nessesary to test thyroid hormone and thyroid antibodies in women with pre-eclampsia.The decrease of FT3 and FT4,the increase of TSH and the presence of TPOAb and TGAb are related with the presence of pre-eclampsia.

Methods: Patients with dry eye who were treated in the Ophthalmology Ward and Outpatient Department of the First Hospital of Hunan University of Chinese Medicine from October 1, 2020, to October 30, 2021 were enrolled as the research participants in the study. They were assigned to two groups based on traditional Chinese medicine (TCM) syndrome types: heat stagnation in liver meridian pattern group and Qi-Yin deficiency pattern group. Healthy volunteers who underwent health check-ups in the Health Management Department were included as healthy group following the random number table method. The tears of the patients and the healthy volunteer participants were tested by high-performance liquid chromatography-mass spectrometry (LC-MS). The differential metabolites were screened out by multivariate statistical analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment was performed on the differential metabolites. Finally, the association analysis of differential proteins and metabolites was conducted to verify and supplement the metabolites. Results: A total of 32 dry eye patients were enrolled, including 16 cases with heat stagnation in liver meridian pattern and 16 cases with Qi-Yin deficiency pattern. Fourteen healthy volunteers were included as healthy group. There were no significant differences in baseline characteristics among the three groups (P > 0.05). A total of 412 biomarkers were determined in Qi-Yin deficiency pattern group, mainly including lipids, lipid-like molecules, organic acids and their derivatives, organic heterocyclic compounds, and nucleosides and their analogues. For heat stagnation in liver meridian pattern group, 112 metabolites were determined, mainly including organic acids and their derivatives, lipids, and lipid-like molecules. The KEGG enrichment results of pathways and the relative content analysis of differential markers demonstrate that purine metabolism and caffeine metabolism pathways are common metabolic characteristics of all dry eyes. Among them, deoxyinosine monophosphate (dIMP) and 2-(formamido)-N1-(5-phospha-D-ribosyl) acetamidine can serve as their biomarkers. The main characteristics of Qi-Yin deficiency syndrome pattern were the significant enhancement of metabolic pathways such as lysine degradation, ovarian steroidogenesis, cholesterol metabolism, pyrimidine metabolism, and bile secretion (P < 0.05). Dry eye associated with the heat stagnation in liver meridian pattern is mainly characterized by inhibition of the valine, leucine, and isoleucine biosynthesis pathways (P < 0.05). Conclusion Metabolomics can be used as an effective basis for TCM syndrome classification. Different patterns of dry eye syndrome exhibit typical characteristics in the types and concentrations of metabolites, which correspond to the syndrome classification in TCM. This study initially confirms the rationality of TCM syndrome classification and provides significant reference for the mechanism of dry eye and drug development.

Objective To investigate treatment effects of levonorgestrel-releasing intrauterine system (LNG-IUS) for adenomyosis with menorrhea in a prospective study. Methods From December 2006 to December 2014, patients of symptomatic adenomyosis diagnosed by transvaginal ultrasound in outpatient or inpatient clinics of Peking Union Medical College Hospital were given the treatment of LNG-IUS. Before and after placement of LNG-IUS, all the patients′parameters were recorded prospectively, including scores of menstruation blood loss, carrying status of IUS, symptoms and scores of dysmenorrhea, biochemical indicators, physical parameters, menstruation patterns and adverse effects. Changes of pictorial chart scores of menstruation and distribution of anemia during follow-up were analyzed. Results Totally 1 100 women meets inclusion criteria, among which 618 cases (56.18%, 618/1 100) had severe menorrhea, with median follow-up period of 28 months (range 1-60 months), and accumulative carrying rate of 66% at 60 months follow-up. After placement of LNG-IUS, compared with baselines, pictorial chart scores and ratio of menorrhea had decreased significantly (all P<0.01), the scroes of menstruation were 157±34, 94±35, 70±33,67 ± 18, 67 ± 20, 65 ± 19, 66 ± 19, 65 ± 21 at 0, 3, 6, 12, 24, 36, 48 and 60 months respectively. During 24 months after placement of LNG-IUS, pictorial chart scores and distribution of anemia had improved significantly compared with preceding period (all P<0.01). We found no dependent factors predicting improvement of pictorial chart scores of menorrhea, which was neither relevant with simultaneous changes of menstruation patterns nor adverse effects (all P>0.05). Conclusions LNG-IUS is effective for adenomyosis of menorrhea. Improvement of menstruation blood loss is independent on patients characters, menstruation patterns or adverse effects.

Objective To investigate the changes of mestruation patterns and adverse effects during the treatment of levonorgestrel-releasing intrauterine system (LNG-IUS) for symptomatic adenomyosis in a prospective cohort study. Methods From December, 2006 to December, 2014, patients of symptomatic adenomyosis diagnosed by transvaginal ultrasound in Peking Union Medical College Hospital were given LNG-IUS. Before and after placement of IUS, all patients′ parameters were recorded, including carrying status of IUS, symptoms and scores of dysmenorrhea, menstruation scores, biochemical indicators, physical parameters, menstruation patterns and adverse effects. Risk factors for changes of menstruation patterns and adverse effects, and their impact on treatment effects were analyzed. Results Totally 1 100 cases met inclusion criteria, with median age 36 years (range 20-44 years), median follow-up 35 months (range 1-108 months). During follow-up changes of menstruation patterns increased significantly with amenorrhea and shortened-menstruation being the most common manifestations. On 3, 6, 12, 24, 36, 48 and 60 months after the placement of LNG-IUS, 0, 5.8%(43/744), 6.9%(47/682), 10.1%(60/595), 17.3%(87/502), 27.2%(104/383) and 29.6%(82/277) patients achieved amenorrhea respectively (P<0.01). Total and subclassification of adverse effects decreased significantly (P<0.01). Within 12 months and >12 months after placement, abdominal pain and body weight increasing ≥5 kg/year were the most common adverse effects. Changes of menstruation patterns, total and subclassifications of adverse effects were neither dependent on patient parameters, treatment modes and treatment effects, nor could predict future LNG-IUS carrying status (all P>0.05). After taking out of LNG-IUS, most changes of menstruation and adverse effects disappeared. Conclusions During the treatment of LNG-IUS for symptomatic adenomyosis, changes of menstruation patterns increase gradually with amenorrhea and shortened-menstruation being the most common manifestations, while adverse effects decrease significantly. Changes of menstruation patterns or adverse effects neither have any risk factor nor have impact on treatment effects.

Conclusion LNG-IUS is effective for adenomyosis of severe dysmenorrhea. Improvement of pain is independent on patients characters, menstruation patterns or adverse effects.

Natriuretic peptides(NPs)are closely associated with acute ischemic stroke(AIS),and previous studies have shown that NPs have the beneficial effects of promoting vasodilation and inhibiting inflammation and apoptosis.The beneficial cardiovascular effects of atrial natriuretic peptide(ANP)and brain natriuretic peptide(BNP)are associated with the natriuretic peptide receptor A/cyclic guanosine monophosphate(cGMP)signaling pathway.With the discovery of C-type natriuretic peptide(CNP)and its dependent receptor natriuretic peptide receptor B in brain tissue,NPs provide new ideas for the diagnosis and treatment of AIS.Recent studies have confirmed the beneficial effects of ANP,BNP,CNP,and their homologous receptors on neuronal damage induced by AIS;however,the specific mechanism of pathways mediated by NPs remains unknown.This article summarizes the studies on NPs,cGMP,and AIS,in order to provide a ref-erence for subsequent studies on NPs in AIS.

Objective:To evaluate the predictive value of the UK Myeloma Research Alliance Risk Profile(MRP)score based on clinical outcomes in elderly patients with newly diagnosed multiple myeloma(NDMM).Methods:Patients aged ≥65 years with NDMM in our hospital from March 2018 to September 2021 were divided into three groups with low, medium and high risk according to MRP scores.Their therapeutic efficacy, adverse effects, and survival were analyzed.Results:A total of 63 NDMM patients were enrolled with median age of 69 years(65-84 years)and median follow-up of 13.3(1.2-43.4)months.Based on MRP score, there were 22 patients in the low-risk group, 13 cases in medium-risk group, 28 patients in the high-risk group.The median progression-free survival(PFS)time of the three groups was 38.4, 25.1 and 21.2 months respectively, and the estimated 2-year PFS rate was 83.9%, 60.0%, and 45.6%, respectively(all P=0.177). The estimated 2-year overall survival(OS)rate was 100.0%, 90.0%, 74.6%, respectively(all P=0.049). Among patients with grade 2 or above hematological adverse events, there were 20 cases(71.4%), 7 cases(53.8%)and 8 cases(36.4%)in the high-, medium-and low-risk groups, with statistically significant differences( χ2=6.154, P=0.046). Among patients with grade 3 or higher non-hematological adverse events, there were 17 cases(60.7%), 5 case(38.5%)and 5 cases(22.7%)in the high-, medium-and low-risk groups, with statistically statistical significance( χ2=7.389, P=0.025). The patients experiencing interruption, delay or replacement of chemotherapy regimen were 6 cases(46.2%)and 19 cases(67.9%)in the medium-and high-risk groups, which were higher than in the low-risk group(31.8%, χ2=6.543, P=0.038). Conclusions:It is feasible to conduct MRP score in elderly NDMM patients.The MRP score can be used to predict the adverse events of chemotherapy, etc, and has certain value for the prognosis evaluation of patients.

Objective This article aimed to explore the inhibitory effect of β-ionone(BI)on the proliferation of breast canc-er cells through the nuclear factor kappa-B(NF-κB)pathway and its possible mechanism.Methods The methylene blue assay and MTT assay were used to determine the viability of breast cancer cells.The malachite green phosphate assay was used to detect the ac-tivity of protein phosphatase 2A(PP2A).Western blot was used to detect the levels of phosphorylated P65(s534 and s311)(p-P65),PP2A(A,B and C),and phosphorylated ataxia telangiectasia mutant(p-ATM)(s1981)protein.Results BI could significant-ly inhibit the proliferation of human breast cancer BT549 cells and MCF-7 cells in a time-and dose-dependent manner,and the difference was statistically significant(P<0.01).After treated with BI,NF-κB activity was significantly inhibited in MCF-7 cells,as shown by a significant decrease in the level of phosphorylated P65(s311 and s534)protein and an increase in the level of PP2A pro-tein,and the difference was statistically significant(P<0.05).In addition,BI also significantly reduced the phosphorylation of P65 protein and ATM protein in MCF-7 cells by the PP2A inhibitor-okada acid(OA).Conclusion This study shows that BI inhibits the proliferation of breast cancer cells by inhibiting NF-κB activity,and its mechanism may be achieved by increasing PP2A activity to regulate the NF-κB pathway.
