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 explore the role and significance of secretory phospholipase A2(sPLA2)in peripheral blood in preterm premature rup?ture of membranes(pPROM)and infection of amniotic cavity. Methods RT-PCR was used to detect the expression levels of sPLA2 mRNA in pe?ripheral blood of 30 patients with pPROM (experimental group),30 non-full term normal pregnant patients without pPROM (normal control group)and 30 full term patients with PROM(full-term control group)before and after delivery. Fetal membranes were collected at the time of deliv?ery of patients with pPROM for pathologic examination to determine histological chorioamnionitis(HCA). Results The expression levels of sPLA2 mRNA in peripheral blood were 1.079±0.746 and 0.651±0.481 in the experimental group and the normal control group before delivery,respectively, indicating that the expression of sPLA2 mRNA was increased in the experimental group compared with the normal control group(P=0.011). The expression levels of sPLA2 mRNA in peripheral blood were 2.439±0.086 and 2.575±0.036 in the experimental group and the full-term control group at labor onset,respectively,indicating that there was no statistically significant difference in the level of sPLA2 mRNA in peripheral blood between the experimental group and the full-term control group at labor onset(P=0.787). The level of sPLA2 was related to chorioamnionitis in the experi?mental group at labor onset. Conclusion The increase of sPLA2 may participate in the pathogenesis of preterm premature rupture of membranes and is related with the infection of chorioamnionitis.

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 treatment effects of levonorgestrel-releasing intrauterine system (LNG-IUS) for adenomyosis with severe dysmenorrhea in a prospective cohort 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 symptoms and scores of dysmenorrhea, menstruation scores, biochemical indicators, physical parameters, carrying status of LNG-IUS, menstruation patterns and adverse effects. Changes of scores and patterns of pain during follow-up were analyzed. Results Totally 1 100 women meets inclusion criteria, among which 640 cases (58.18%, 640/1 100) had severe dysmeorrhea, with median follow-up period of 35 months (range 1-60 months), and accumulative carrying rate of 65% at 60 months follow-up. After placement of LNG-IUS, scores of pain and ratio of severe dysmenorrhea had decreased significantly compared with baselines (all P<0.01), the scroes of visual analog scale (VAS) were 8.1 ± 0.9, 5.5 ± 2.4, 4.6 ± 2.4, 3.3 ± 2.2, 2.2 ± 2.1, 2.2 ± 1.8, 1.4 ± 1.6 and 1.3 ± 1.3 at 0, 3, 6, 12, 24, 36, 48 and 60 months respectively. During 36 months after placement of LNG-IUS, scores of pain had improved significantly compared with preceding period (all P<0.01). We found no universal dependent factors predicting improvement of pain, which was neither relevant with simultaneous changes of menstruation patterns nor adverse effects (all P>0.05). Conclusion LNG-IUS is effective for adenomyosis of severe dysmenorrhea. Improvement of pain 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.

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 To prospectively observe the effect of levothyroxine treatment on neuropsychological development in offspring of pregnant women with subclinical hypothyroidism. Methods Twenty-three pregnant women with subclinical hypothyroidism received levothyroxine therapy (SCH+LT4 group) and 17 who did not receive levothyroxine ( SCH group) were enrolled; 24 pregnant women with normal thyroid function were referred as controls (C group). All the subjects underwent the planned thyroid tests regularly. Serum TSH, TT4, FT4, TT3,FT3, TPOAb, and TgAb levels were determined. Their 14-30 month-old children underwent the tests relating to intelligence and motor activity with the Bayley scale. Results In SCH group, SCH+LT4 group, and C group, the MDI were 115. 12, 118.56, and 117.63, respectively. And the PDI were 115.47, 120.65, and 117.50,respectively. The MDI and PDI were the highest in SCH+LT4 group and were the lowest in SCH group. Serum TSH levels remained above 2.0 mIU/L during the whole course of pregnancy in SCH group and higher than that in C group at all time points ( P＜0.05 ). Serum TT4 and FT4 levels were lower in SCH group than in C group at all time points except G28 and G32. The baseline TSH level in SCH+LT4 group was the highest ( P＜0.01 ), their TT4 and FT4 levels were the lowest among the three groups. In SCH + LT4 group, serum TSH, TT4, and FT4 levels were similar to C group after L-T4 treatment. Conclusion The prompt L-T4 treatment can maintain normal TSH levels in pregnant women with subclinical hypothyroidism during the whole course of pregnancy, and impairment of neuropsychological development in infants may be avoided.

Objective To use the first trimester-specific reference intervals of thyroid-related hormones to explore the prevalence of thyroid dysfunction during early pregnancy and to analyze effectiveness of different screening strategies. Methods In this study 2 899 pregnant women were enrolled during the first trimester of gestation. TSH, FT4, FT3, and thyroid peroxidase antibody (TPOAb) were measured and thyroid disorders of pregnant women were diagnosed based on the first trimester-specific reference intervals. Results The prevalence of hypothyroidism was significantly higher in the high-risk group than in the non-high risk group ( 16.3% vs 5.3%,RR = 3.1,95% CI 2.4-4.0, P＜0.01 ). TPOAb ( RR = 4.7, 95 % CI 3.6-6.0, P＜0.01 ), and personal history of thyroid diseases ( RR=3.2, 95% CI 1.9-5.4, P＜0.01 ) increased the risk of hypothyroidism. The prevalence of hyperthyroidism was higher in the high-risk group (3.1% vs 1.4%, P = 0. 006, RR = 2.2, 95% CI 1.2-3.9, P=0.006). TPOAb (RR=2.6, 95%CI 1.3-5.0, P=0.007), and presence of personal history of thyroid diseases( RR=4.7, 95% CI 1.7-12.5, P=0.006) also increased the risk of hyperthyroidism. 56.7% women with hypothyroidism and 64. 7% women with hyperthyroidism were in the non-high risk group. Conclusion We recommend that screening all pregnant women for thyroid disorders in the first trimester with TSH, FT4, and TPOAb is more effective than the case-finding approach.
