Objective To evaluate the impact of subclinical hypothyroidism (SCH) on the outcome of pregnancy and the therapeutic effect of L-T4.Methods A total of 1 786 pregnant women during the first, second, and third trimesters were enrolled for thyroid screening by determining serum free thyroxine (FT4), total thyroxine (TT4), thyrotropin (TSH), and thyroid peroxidase antibody;123 pregnant women with SCH were successfully divided into treated group (n =42) and untreated group (n =81).The treated group was treated by L-T4 based on American Thyroid Association (ATA) 2011 guideline.Collected items include obstetric outcomes and complications.Results (1) Compared to control group, the rate of spontaneous abortion in pregnant women during first trimesters was increased in SCH group (20.99％ vs 8.45％, x2 =12.96, P =0.00), with higher incidence of diabetes during second trimester (24.69％ vs 10.45％, x2 =14.11, P =0.00).The incidences of hypertension during pregnancy, premature delivery, ablatio placentae, placenta praevia, fetus growth restriction, and low birth weight showed no difference between two groups (all P ＞ 0.05).(2) Compared with the untreated group, the incidences of spontaneous abortion and diabetes were decreased in the treated group (7.14％ vs 20.99％, x2 =3.89, P =0.05;9.52％ vs 24.69％, x2 =4.05, P =0.04), while the incidences of hypertension, premature delivery, ablatio placentae, placenta praevia, fetus growth restriction, and low birth weight infant accident rate were not different between two groups (all P ＞ 0.05).Conclusions SCH during the frist trimester is a risk factor of spontaneous abortion;SCH during the middle stage of pregnancy is a risk factor of gestational diabetes mellitus.Treatment of SCH with L-T4 may be beneficial.

OBJECTIVE:To observe clinical efficacy of extracorporeal shock wave lithotripsy combined with Paishi decoction in the treatment of kidney stone. METHODS:160 patients with kidney stone were selected and randomly divided into observation group and control group,with 80 cases in each group. Control group only received HB-ESWL-VG extracorporeal shock wave litho-tripsy;observation group additionally received Paishi decoction 300 ml,tid,for consecutive 1 week,on the basis of control group. Clinical efficacy was observed in 2 groups;the levels of serum inflammatory factor IL-2,IL-6,TNF-α,T lymphocyte subset CD3+,CD4+,CD8+ and CD4+/CD8+,erythrocyte immune function indicator C3b receptor rosette(C3bRR),immunity complex ro-sette(ICR)and tumor erythrocyte rosette(TER)level were detected in 2 groups before and after treatment. RESULTS:The effec-tive rate of observation group(98.75%)was significantly higher than that of control group(91.25%),with statistical significance (P<0.05). After treatment,the levels of IL-2,IL-6 and TNF-α in observation group was significantly lower than in control group, the levels of CD3+,CD4+,CD4+/CD8+,C3bRR,ICR and TER were significantly higher than control group,with statistical signifi-cance(P<0.05). Comparsion of CD8+between 2 groups was not statistically significant(P>0.05). CONCLUSIONS:The extracor-poreal shock wave lithotripsy combined with Paishi decoction can relieve inflammation reaction,enhance immune function and im-prove therapeutic efficacy.

OBJECTIVE To investigate the drug resistance in Ureaplasma urealytium(Uu)from 2005 to 2007 in Ningbo city and guide rational drug administration in clinics.METHODS Twelve kinds of antibiotics sensitivity test in Uu which was isolated in clinics from 2005 to 2007 were analyzed retrospectivly.RESULTS The detection rate of Uu from 2005 to 2007 was 47.25%,52.66% and 61.94%,respectively.Compared with in 2005(19.96%),the resistance increased obviously to erythromycin and roxithromycin(P0.05).CONCLUSIONS Drug resistance of Uu is changing.It is necessary to monitor the local drug resistance of Uu regularly to guide reasonable administration in clinics.

Totally 1 360 pregnant women during the first trimesters (4-12 weeks) who visited Ningbo University Affiliated Hospital and Ningbo Jiangbei Maternal Health Hospital from February 2010 to October 2011,and 216 non-pregnant healthy women,who contemporaneous by visited the hospital,were enrolled in this study.The thyroid screening was made by determining urinary iodine and serum free thyroxine,free triiodothyronine,total thyroxine,total triiodothyronine,thyrotropin,and thyroid peroxidase antibody (TPOAb).The median concentration of urinary iodine in the pregnant women was not different from that of non-pregnant women (P＞0.05) ; 1 360 pregnant women were screened,268 (19.71％) of them were identified to suffer from thyroid disorders or with positive thyroid autoantibody.29(13.43％) of non-pregnant women were identified to suffer from thyroid disorders or with positive thyroid autoantibody.There was significant difference between the 2 groups (x2 =4.40,P＜0.05).Prevalence of thyroid dysfunction may increase during early pregnancy.The screening for thyroid function and autoantibody should be recommended in that period.

BACKGROUND:Studies have shown that low-intensity and short-time vibration with a certain frequency can reduce the absorption of bone tissue and increase the quantity and quality of bone through promoting the proliferation and differentiation of osteoblasts.
OBJECTIVE:To investigate the effects of different frequencies of vibration strains on cycle, proliferation and differentiation potency of RAW264.7 cel s cultured in vitro.
METHODS:Passage 6 RAW264.7 cel s in good conditions were randomly divided into six groups, and each group was induced cultured with Dulbecco’s modified Eagle’s medium containing receptor activator of nuclear factor kappa B ligand. The final concentration of receptor activator of nuclear factor kappa B ligand was adjusted to 50μg/L, and then kept without changes. The non-loading group did not loaded with vibration strain, and the other five groups were loaded with 3-10 Hz, 15-35 Hz, 35-45 Hz, 50-70 Hz and 70-90 Hz vibration strains on the RAW264.7 cel s respectively. The other vibration parameters were consistent;the vibration time was 15 min/time with the vibration intensity of 0.3 g, twice per day. The cel cycle and cel proliferation were detected at 3 and 6 days after loading of vibration strains.
RESULTS AND CONCLUSION:After composite vibration loading for 6 days, the cel cycle phase in the vibration groups was changed to some extent when compared with the non-loading group. Compared with non-loading group, the cel number in the G 1 phase of the vibration group was significantly increased (P<0.01);the cel number in the S phase and G 2+M phase of the vibration group was significantly decreased (P<0.01);the vibration parameters in the vibration group were significantly decreased (P<0.01). The results indicate that different frequencies of vibration strains can affect the cel cycle and proliferation, and can inhibit the proliferation and differentiation of osteoblasts.

It has been previously thought that calcification is a feature of the stability of atherosclerotic plaques. However, recent studies have shown that microcalcification in atherosclerotic plaques is significantly associated with plaque vulnerability. The relationship between atherosclerotic plaques and calcification is unclear, and the specific role of calcification in atherosclerotic plaques remains controversial.

Objective To investigate the association between heme oxygenase-1 (HO-1) gene rs2071746 polymorphism and long-term clinical outcome in patients with ischemic stroke.Methods Between July 2015 and June 2017,consecutive patients with acute ischemic stroke admitted to the Department of Neurology,the Third Affiliated Hospital of Soochow University were enrolled prospectively.TOAST classification was performed for all patients.Genotyping of the HO-1 gene rs2071746 polymorphism was performed using a modified multiplex ligase detection reaction technique.The patients were followed up.The primary endpoint events included ischemic stroke,vascular death,and myocardial infarction.Multivariate Cox proportional hazard regression model was used to analyze the independent influencing factors for primary endpoint events.Results A total of 1 698 patients with successful genotyping and follow-up information were enrolled.Genotyping showed that the frequency of rs2071746 A allelewas 44.91％.They were followed up for 15.21 ± 7.39 months,and 168 patients (9.89％) had primary endpoint events.The incidence of primary endpoint events in A allele carriers was significantly lower than that in non-A allele carriers (8.80％ vs.12.40％;P =0.018).Multivariate Cox proportional risk regression model showed that after adjusting for age,gender,hypertension,diabetes mellitus,smoking,alcohol consumption,and genotype,A allele was an independent protective factor for primary endpoint events in patients with acute ischemic stroke (hazard risk [HR] 0.693,95％ confidence interval [CI]0.506-0.949;P=0.022).Subgroup analysis showed that carrying the A allele was an independent protective factor for primary endpoint events in patients with large atherosclerotic stroke (HR 0.651,95％ CI 0.425-0.997;P=0.048),while rs2071746 polymorphism was not associated with long-term outcome in other etiological subtypes.Conclusion The HO-1 gene rs2071746 A allele may be a protective factor for the long-term outcome in patients with acute ischemic stroke and large atherosclerotic stroke.
