ObjectiveTo observe the clinical efficacy of electroacupuncture at Baihuanshu (BL30) and Huiyang (BL35) in treating chronic abacterial prostatitis.MethodSixty patients with chronic abacterial prostatitis were divided into a treatment group(n=30) and a control group (n=30), respectively to receive electroacupuncture plus Chinese herbal medicine and Chinese herbal medicine alone.ResultAfter intervention, the scores of National Institutes of Health-Chronic Prostatitis symptom index (NIH-CPS) dropped in both treatment and control groups, while the decrease was more significant in the treatment group (P<0.05); the pain or discomfort score from the NIH-CPS dropped in both groups, while the decrease was more marked in the treatment group (P<0.05).ConclusionElectroacupuncture and Chinese herbal medicine both are effective in treating chronic abacterial prostatitis, and electroacupuncture plus Chinese herbal medicine can produce a more significant efficacy than Chinese herbal medicine alone.

Objective To observe the effect on Foxg1 gene expression in the subgranular zone (SGZ) of cerebral tissue from neonatal rats with hypoxic-ischemic brain damage (HIBD) after transplantation of neural stem cells (NSCs) derived from umbilical cord blood.Methods Mononuclear cells separated from umbilical cord blood by density gradient centrifugation were cultured with orientated induction to differentiate the NSCs.The neuronal phenotype was identified using immunocytochemical methods.A total of 150 Sprague-Dawley rats were randomly divided into a sham-operation group,an HIBD group and an HIBD-NSCs group.Rats in the HIBD group and the HIBD-NSCs group were subject to ligation of the left carotid artery and then kept in a box under 8％ oxygen and 92％ nitrogen for 2.5 hours to establish the HIBD animal model.The artery was separated but not ligated in the sham operation group,which was not subjected to hypoxia.Twenty-four hours after the operation,the cultivated NSCs were transplanted by caudal vein injection into the rats in the HIBD-NSCs group.Rats were then sacrificed on the 3rd,7th,14th,21st and 28th days after the operation.Foxg1 gene expression in the SGZ was examined using in-situ hybridization methods.Results The number of Nestin-positive cells peaked on the 6th day of cultivation and then decreased by the 9th day.The Foxg1 gene was expressed in the SGZs of each group.The expression increased by the 3rd day after surgery in the HIBD and HIBD-NSCs groups,and peaked on 7th day after the operation,then declined gradually.The average expression level of Foxg1 in the HIBD group was significantly lower than that in the HIBD-NSCs group on the 7th day and thereafter.Conclusions Human umbilical cord blood mesenchymal stem cells can be induced and differentiated into neural stem cells.Foxg1 genes can still be present in the SGZ after birth.HIBD can induce the expression of Foxg1 genes.Transplanting NSCs can promote the expression of Foxg1 genes and improve morphological and functional recovery after HIBD,at least in neonatal rats.

Objective To study on virulence characteristics and multilocus sequence type of Vibrio parahaemolyticus isolated from clinic in Beijing Tongren hospital.Methods Total 152 strains of Vibrio parahaemolyticus isolates were collected from diarrheal patients of outpatients in Beijing Tongren Hospital,Capital Medical University from 2009 to 2011.PCR was used to detect hemolysin gene thermo stable direct themolysin gene (tdh),TDH-related hemolysin gene (trh),type Ⅲ secretion system 2 (T3SS2α,T3SS2β)and systematic functional gene (toxRS/new,orf8) for pandemic 03∶ K6 clone and its derivatives.The genetic features of these strains were determined by multilocus sequence typing (MLST).Results 96％ (146/152) VP harbored tdh gene,2％ (3/152) VP harbored trh gene and 100％ (152/152) VP harbored T3SS2 gene.In this study there were 107 pandemic strains (both tdh and toxRS/new positive and trh negative),38 pathogenic strains (tdh positive and/or trh positive) and 6 nonpathogenic strains (both tdh and trh negative).All nonpathogenic strains harbored systematic functional gene (toxRS/new,orf8).Only one pathogenic strains harbored orf8 gene.One clone harbored all virulence gene.In this study there were 16 sequence types,and ST3 is the pandemic sequence type,including 113 strains,and four new sequence types were found.Conclusions In this study more than 90％ Vibrio haemolyticus harbored tdh gene and ST3 was the pandemic sequence type in Beijing.One can get bacterial pathogenic charateristic and population genetics information by virulence gene testing and MLST.

Objective To initially establish an occupational well-being questionnaire for Chinese clinical nursing staffs.Methods The draft questionnaire,including open-ended questions and semi-structured interview,was established according to literature review and revised after expert′s consultation and pilot survey. Then,the questionnaire was tested by 460 nurses who randomly selected from a Class Ⅲ Grade Ⅰ hospital in Wuhan province from September 201 4 to June 201 5.The reliability and validity of the questionnaire were examined by exploratory factor principal component analysis,confirmatory factor analysis of maximum likelihood estimation method,and the Cronbach′s αanalysis.Results The questionnaire contained 1 9 items belonging to 5 dimensions that included welfare,value,interpersonal relationship,leaders and characteristics.The Cronbach′sαcoefficient for the questionnaire and each dimensions were 0.91 4 and 0.753-0.862.The correlation coefficients between each items and the total score as well as its related dimension were 0.487-0.729 and 0.709-0.883.The accumulative contribution rate of the five factors was 71 .1 05%.Conclusions The nurses′occupational well-being questionnaire is a reliable and valid instrument to assess the occupational well-being for clinical nursing staffs.

Objective:To explore the effects of applying peer-assisted learning (PAL) combined with modular teaching in physiology education, and to explore a more suitable mode for physiology teaching and learning.Methods:We selected a total of 89 undergraduate medical students of grade 2022 from a university offering physiology courses from February 28 to June 30, 2022. They were assigned using a random number table into experimental class (44 students) and control class (45 students). The experimental class adopted PAL with modular teaching, while the control class adopted the online and offline hybrid teaching method. The two classes were compared for teaching effects in terms of the completion rate of task points, final assessment scores, and questionnaire results. SPSS 19.0 was used to perform the independent samples t-test and the chi-square test. Results:The final exam scores for the objective questions of the experimental class and the control class were (43.04±3.25) and (40.24±8.64), respectively; the scores for the subjective items were (44.49±2.80) and (39.21±5.71), respectively; and the total scores were (87.53±4.24) and (79.40±12.08), respectively, all with significant differences between the two classes. There were significant differences in students' learning autonomy, micro-video preview rate, problem discussion participation rate, unit self-test participation rate, and after-class homework completion rate. The questionnaire survey showed that students in the experimental class believed that this teaching model was helpful for improving students' comprehensive qualities.Conclusions:PAL combined with modular teaching can effectively improve physiology teaching effects and students' learning autonomy and comprehensive abilities.

Objective To investigate the prevalence of hypothyrodism during the first half of pregnancy in the Han nationality women in iodine-adequate area. Methods TSH, FT4 and thyroid peroxidase antibody (TPOAb) levels were detected in 4 800 pregnant women during the first half of pregnancy. Both gestational age-specific reference intervals and population-based reference intervals of thyroid function were applied and the corresponding prevalences of hypothyroidism were compared with each other. Results Based on the gestational age-specific reference intervals, the prevalences of overt hypothyroidism at 4th and 8th weeks of gestation were 1.03%, 0.37% respectively. At 4th, 8th, 12th, 16th and 20th weeks of gestation, the prevalences of subclinical hypothyroidism were 4.59%, 6.15% , 4.68%, 4.53%, 5.96% respectively, while those of hypothyroxinemia were 3.69%, 1.11%, 2.92% , 1.29%, 2.29%, respectively. According to the pepulation-based reference intervals, the rates of missed diagnosis of subclinical hypothyroidism were 0.18%, 2.85%, 4.10%, 3.24%, 3.21% while those of hypothyroxinemia were 3.45%, 0.66%, 2.34%, 1.29%, 1.83%, respectively. During 4th, 8th, 16th weeks of gestation, the positive rates of TPOAb in the group with subclinical hypothyroidism were significantly higher than those with euthyroidism. The prevalences of subclinical hypothyroidism in TPOAb positive group were obviously higher than those in TPOAb negative group at 4th, 8th, 12th, 16th gestational weeks. Conclusion The rates of missed diagnosis of subclinical hypothyroidism and hypothyroxinemia during the first half of pregnancy were decreased by applying the gestational age-specific reference intervals in this prospective study. Positive TPOAb is a risk factor for subclinical hypothyroidism during the first half of pregnancy.

Objective To investigate the prevalence of gestational transient thyrotoxicosis(GTT) and analyze the cause of thyrotoxicosis encountered in this period MethodsAn epidemiologic survey in ten hospitals in Shenyang was performed and 534 pregnant women during the first trimester of pregnancy filled questionaire,received physical examination and had serum thyroid-stimulating hormone(TSH),free T4 (FT4),free T3(FT3),thyroid peroxjdase antibody(TPOAb),thyrotrophin receptor antibody(TRAb),and human chorionic gonadotrophin(hCG)tests.Results(1)The total prevalence of thyrotoxicosis was 9.75%(52/534)in the first trimester and the prevalence of Grrr was 7.86%.which accounted for 80.77%of the thyroxicosis encountered in this period.A total of 88.89%of the overt GTT showed only elevated FT3 level.(2)The level of serum hCG increased gradually in the first trimester.The medians of hCG were 25 300,85 220 and 81 780 IU/L 6,8-10 and 12 weeks after gestation.respectively(P=0.000).The medians of serum TSH were 1.45.1.10 and 0.84 mlU/I,6.8-10 and 12 weeks after gestation,respectively(P＜0.01).(3)When segum hCG was more than 50 000 IU/L,the prevalece of GTT increased obviously.When serum hCG was between 80000 IU/L and 110000 IU/L,subclinical GTT increased significantly.When serum hCG was more than 110000 IU/L,overt GTT increased significantly.Correlation analysis showed that serum hCG was related negatively with TSH(r=-0.402,P=0.000)and positively with FT3(r=0.165,P=0.000),but not related with FT4.Conclusions The prevalence of GTT is 7.86%in the first trimester and it is the main cause of thyrotoxicosis found in the first trimester,accounting for 80.77%of all the causes.The serological characteristic of overt GTT is mainly the elevation of serum FT3 leveL Serum hCG level is related with the severity of GTT.

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.

Objective To establish the gestational month-specific reference intervals for thyrotropin and thyroxine in Han nationality women in iodine sufficient area of China. Methods In iodine sufficient area of China, 120 non-pregnant women and 1 118 pregnant women at gestational ages from 4 to 36 week (4 weeks≈1 month) were collected according to the strict criteria. Urinary iodine excretion and serum thyrotropin (TSH), total thyroxine (TT4), free thyroxine (FT4), thyroid peroxidase antibody (TPOAb) levels were determined in all subjects. Results During pregnancy, serum TSH increased at week 4, and then began to decrease with the lowest level at week 12, which was 35% lower than the non-pregnant level." After that, serum TSH increased gradually and finally became stable during the third-trimester of pregnancy (T3) when the level was 29% higher than that of non-pregnant controls. Serum TT4 elevated dramatically during the first-trimester with peak at week 16, which increased by 70% compared with the non-pregnant level, then slightly decreased, and became steady with 50% increasing compared with non-pregnant level. Serum FT4 initially increased slightly with peak at week 4, and then decreased gradually until the beginning of T3 without obvious fluctuation during T3. Conclusion The gestational month-specific reference intervals for TSH, TT4 and FT4 are necessary for the early diagnosis of maternal subclinical hypothyroidism and hypothyroxinaemia.

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.
