Objective To analyse the relationship and mechanism between chronic periodontitis (CP) and IgA nephropathy (IgAN) by establishing animal model of chronic periodontitis and IgA nephropathy in SD rats.Methods Eighty health male SD rats were divided into four groups,control group (A,n=20),IgAN group (B,n=20),CP group (C,n=20),CP accompanied with IgAN group (D,n=20).CP model was established by ligating silk suture and besmeared pathogenic bacterium in rats dental cervix.Experimental IgAN model was established by lavage of bovine serum albumin (BSA) and injection of lipopolysaccharide (LPS) and carbon tetrachloride (CCl4).Ten rats were sacrificed in every group at the end of week 8 and 12.The blood,urine,kidney tissue samples were examined.The observation index included proteinuria,kidney and liver function,renal tissue pathology and periodontal tissue pathology.The data were statistically analysed.Results Animal models were established successfully.The levels of Scr and BUN in group A,B,C were not obvious difference,but that in group D was higher than the other third groups at 8 weeks (P ＜ 0.05).The levels of Scr and BUN in group D and group B were significantly higher than that in group A,meanwhile that in group D was significantly higher than that in group B at 12 weeks(P ＜ 0.05).The levels of 24 h urine protein in B,C,D groups were higher than that in group A at 8 weeks(P ＜ 0.05),but at 12 week,that in group D was higher than that in group B and C (P ＜ 0.05).At 8 weeks,glomeruli had little mesangial broadening and renal interstitium had mild hyperplasia of fibrous tissue in group B and D,and that in the group D significantly was heavier than that in group B.The focal varying degrees were glomerular mesangial proliferation hardening,glomerular mesangial broadening,focal segmental sclerosis,and diffuse or focal inflammatory cell infiltration in D group at the end of week 12.The score of PAS between group A and group C had no statistical significance.The scores of PAS in group B and D were higher than that in group A (P ＜ 0.01),and that in group D was higher than that in group B (P ＜ 0.01).Obvious inflammation of periodontal tissue was observed in group C and D,and modified sulcus bleeding index (MBI) were higher than that in group A and B,and MBI in group D was significantly higher than that in group C (P ＜ 0.01).Conclusions The model can be used to research the change of biochemistry and pathology and observe the relationship between chronic periodontitis and IgAN.This study shows that there is relationship between chronic periodontitis and IgAN.Chronic periodontitis maybe make more serious pathology damage in kidney by inflammation mechanism.

Objective To explore the efficacy and side effect of inductive chemotherapy with lowdose,cytarabine,homoharringtonine and granulocyte colony-stimulating factor(CHG) in elderly acute myeloid leukemia(AML). Methods Thirty-five elderly patients (age＞60 years) with AML were enrolled for the initial treatment with CHG regimen,The CHG regimen consisted of cytarabine 10 mg/m2 per 12 h by subcutaneous injection,days 1-14,homoharringtonine 1 mg/m2 per day by intravenous continuous infusion,days 1-14,and G-CSF 200 μg/m2 per day by subcutaneous injection 12 h before chemotherapy,days 0-14. G-CSF only was used when white blood cell count(WBC) was less than 20×109/L during the whole course. Results After the first course,12 patients achieved complete response (CR),15 patients achieved partial response(PR),and 8 patients had no response(NR). After the second course,5 of 15 PR patients achieved CR,2 of 8 NR patients achieved PR. The total effective rate was 82 % (29/35). Of those 17 CR patients,eleven patients continued maintenance therapy and remained in remission for 12-34 months with a median CR duration of 18 months,the other 6 patients relapsed and were treated with original regimen,including one achieved CR again,4 achieved PR,and 1 achieved NR. The CHG regimen had mild hematologic toxicities and no severe nonhematologic toxicities. Conclusion CHG regimen is effective and well tolerated in remission for elderly AML.

Methods One hundred and fourty children with autism and 82 ordinary children were reviewed by self-written general circumstance questionnaire and risk factor questionnaire. Results Viral influenza during pregnancy (x2 =15.29) ,bom suffocate( x2 =6. 04) , premature delivery (x2 =6. 48) , dystocia (x2 =2. 83) and artificial feeding ( x2 = 6. 02 ) were risk factors for children autism (P < 0. 05 ). Conclusion Childeren autism is associated with risk factors in rinatal period. Early dectecion and early prevention and treatment may improve the outcome.

Objective To evaluate the relationship between the anxiety condition and educational background of the autistic children's parents. Methods Questionnaires for the self-evaluation of anxiety were collected from the parents of 140 children with autism. Results The autistic children's mothers had significantly higher score of anxiety than the fathers (42. 73 ±8. 25) (t =6. 783,P ＜0. 05). The autistic boy's parents had significantly higher anxiety pressure than autistic girl's parents ( 51.38 ± 11.24 vs. 43.23 ± 6. 12) ( t = 4. 894,P ＜0. 05). The anxiety intensity of the autistic children's parents was negatively correlated with the parents'educational background ( F = 10. 788, P ＜ 0. 05 ). Conclusion The autistic children' s parents had certain anxiety,which is correlated with the their educational background and genders of the autistic children. It is necessary to interfere the negative mood to facilitate the treatment of the autistic children.

Objective To investigate the possible correlation between chronic periodontitis(CP)and chronic renal failure(CRF)by establishing chronic periodontitis and chronic renal failure model in SD rats. Methods Forty health male SD rats were divided into four groups: control group(A), CP group(B), CRF group(C), CP accompany with CRF group(D). Ten rats were sacrificed in every group at the end of week 8. The periodontal index, levels of serum Scr and BUN, the concentration of IL-1β and TNF-α were examined. The severity CP and CRF was quantified by histopathology. The date was statistically analyzed. Results Animal models were established successfully. Scr and BUN in group D, BUN were higher than that in group C[Scr(120.54±21.29)junol/L vs(93.63±18.82)u,mol/L, BUN(34.20±14.44)mmol/L vs(17.77±4.15)mmol/L, P<0.05]. The kidney change of inflammation was observed in group B, the grade of PAS and Masson in group C and D were higher than that in group A(P<0.01), and that in group D was higher than group C(P<0.05). Obvious inflammation of periodontal tissue was observed in group B and D. Attachment loss level(AL)in group D was higher than that in group B[(173.60± 16.75)μm vs(124.00±23.87)μm, P<0.05]. The level of IL-lβ and TNF-α in group B and C and D were higher than that in group A(P<0.05), and IL-lβ in group D was higher than that in group B and C(P<0.05), TNF-a in group D was higher than that in group B(P<0.05). 2×2 factorial design revealed that there were interactions between CP and CRF on the numerus of Scr and BUN and AL P<0.05), and the influence of each factor on that was significant(P<0.05), no interactions were noted between CP and CRF on IL-1β and TNF-α(P>0.05), but the influence of each factor on that was significant(P<0.05). Conclusions The SD rat models can appear chronic periodontitis and chronic renal failure at the same time. There is correlation between chronic periodontitis and chronic renal failure. Chronic periodontitis can aggravate chronic renal failure throngh the role of inflammation.

OBJECTIVE To investigate the effect of Turkish galls extract (TGE) on the expression of IgA in serum,urine and renal tissue of IgA nephropathy (IgAN) model rats.METHODS Fifty healthy male Sprague Dawley rats were randomly divided into normal control group,IgAN model group,and TGE 75,150 and 300 mg· kg-1 groups,10 rats per group.The model of IgAN rats was established with bovine serum albumin (BSA)+lipopolysaccharide (LPS)+carbon tetrachlorid (CCl4)for 12 weeks.From the 13th week,TGE was ig administrated once a day for 4 weeks.At the end of the 12th and 16th weeks,24 h urine protein was measured by BCA method.At the end of the 16th week,serum and urinary IgA levels were measured by enzyme linked immunosorbent assay(ELISA),serum creatinine(SCR) and blood urea nitrogen (BUN) were detected by an automatic biochemical analyzer,and the renal pathological changes were evaluated with an Oxford classification scoring system.The deposition of IgA immune complex in the kidney was observed by immunofluorescence assay.RESULTS At the end of 12th week,24 h urine protein increased in all IgAN groups (P＜0.05),compared with normal control group.At the end of 16th week,24 h urine protein,IgA content in serum and urine,SCr and BUN content in serum,score in Oxford classification of renal tissue and deposition of IgA immune complex in the kidney in IgAN model group were all higher than in normal control group (P＜0.05).Compared with IgAN model group,24 h urine protein,IgA content in serum and urine and SCr content in serum were decreased in all TGE groups (P＜0.05),and BUN content in serum and deposition of IgA immune complex in the kidney decreased in TGE 150 and 300 mg·kg-1 groups (P＜0.05).The score in Oxford classification of renal tissue was decreased in TGE 300 mg· kg-1 group only.CONCLUSION TGE has curative effect on IgAN model rats by reducing serum and urinary IgA and decreasing IgA immune complex deposition.

Objective:To explore the relationship between iodine and hypothyroidism.Methods:Patients with primary hypothyroidism (hypothyroidism group) and healthy people (control group) from Linfen City who first came to the Affiliated Hospital of Shanxi Institute for Endemic Disease Prevention and Treatment in 2017 and 2018 were selected as the research subjects. One random urine sample and fasting venous blood sample were collected from the research subjects. The levels of urinary iodine, blood iodine and serum total triiodothyronine (TT 3), total thyroxine (TT 4), free triiodothyronine (FT 3), free thyroxine (FT 4), thyroid stimulating hormone (TSH), anti-thyroglobulin antibody (TgAb) and anti-thyroid peroxidase antibody (TPOAb) were detected. According to the results of TSH level, hypothyroidism group was divided into hypothyroidism Ⅰ group (TSH≥10.00 mU/L) and hypothyroidism Ⅱ group (4.20 mU/L < TSH < 10.00 mU/L), and they were compared with control group (0.27 mU/L≤TSH≤4.20 mU/L). Results:A total of 97, 96 and 175 research subjects were included in hypothyroidism Ⅰ group, hypothyroidism Ⅱ group and control group, respectively. There was no significant difference in urinary iodine levels among the three groups ( H = 0.631, P > 0.05). The blood iodine levels [(40.70 ± 21.08), (58.59 ± 14.55), (59.50 ± 11.89) μg/L] in the three groups were significantly different ( F = 50.559, P < 0.01), and the blood iodine level in hypothyroidismⅠgroup was lower than that in hypothyroidism Ⅱ group and control group ( P < 0.01). The levels of TT 3 [median (interquartile range): 1.59 (0.99, 2.05), 2.25 (1.98, 2.59), 2.14 (1.89, 2.49) nmol/L], TT 4 [35.18 (16.06, 70.23), 105.68 (83.38, 133.19), 107.18 (89.92, 128.30) nmol/L], FT 3 [3.48 (1.94, 4.52), 5.01 (4.57, 5.50), 5.02 (4.64, 5.55) pmol/L] and FT 4 [7.14 (3.12, 10.76), 15.31 (13.87, 17.11), 16.69 (14.87, 18.20) pmol/L] in the three groups were significantly different ( H = 66.197, 142.461, 94.508, 166.557, P < 0.01). After further pairwise comparison, the levels of TT 3, TT 4, FT 3, and FT 4 in hypothyroidism Ⅰ group were significantly lower than those in hypothyroidism Ⅱ group and control group ( P < 0.01). The levels of TgAb and TPOAb in the three groups were significantly different ( H = 85.507, 101.726, P < 0.01). After further pairwise comparison, the levels of TgAb and TPOAb in hypothyroidismⅠgroup were significantly higher than those in hypothyroidism Ⅱ group and control group ( P < 0.01); and the levels of TgAb and TPOAb in hypothyroidism Ⅱ group were significantly higher than those in control group ( P < 0.01). The correlation analysis showed that urinary iodine was positively correlated with blood iodine ( r = 0.170, P < 0.05); blood iodine was positively correlated with TT 3, TT 4, FT 3, and FT 4 levels ( r s = 0.484, 0.594, 0.383, 0.509, P < 0.01), and it was negatively correlated with TSH level ( r s = - 0.373, P < 0.01). Conclusion:Hypothyroidism patients with TSH≥10.00 mU/L may have low blood iodine level.

Objective To study the effect of comprehensive nursing of Traditional Chinese Medicine (TCM) on activity of daily living (ADL) and motor function of patients with hemiplegia after stroke. Methods 72 patients were divided into treatment group and control group randomly. The 36 patients in the treatment group were nursed with comprehensive nursing, such as TCM dietary, emotion regulation, acupoints massage, while the other 36 patients in the control received routinely TCM apoplexy nursed. They were assessed with ADL and motor assessment scale (MAS). Results The scores of both ADL and MAS improved significantly in the treatment group compared with that of the control (P<0.01). Conclusion Comprehensive nursing of TCM can facilitate the recovery of ADL and motor function in patients with stroke.
