Objective To study the effects of quantitative 24-hour urinary protein on the thyroid hormone levels in patients with severe preeclamp-sia,and clarify the impact of severe urinary protein on hypothyroid in severe preeclampsia patients. Methods A total of 166 patients with severe pre-eclampsia were recruited for the study and divided into mild proteinuria group(2.0-4.9 g/d),midrange group(5-10 g/d)and severe group(>10 g/d)according to the quantitative 24-hour urinary protein. 268 healthy female individuals with normal blood pressure and uric routine in the same stage of pregnancy and of the same age were selected into control group. Serum thyrotropin(TSH),free triiodothyronine(FT3)and free thyroxine (FT4)levels were determined by solid-phase chemiluminescent enzyme immunoassay method(CMIA). The thyroid peroxidase antibody(TPOAb) and thyroglobulin antibody(TGAb)concentration were detected by electrochemiluminescent assay(ECLIA). Results TSH levels were signifi-cantly higher in patients comparing to the control group(P<0.01). In addition,severe group showed higher TSH levels than mild group(P<0.01). FT4 and FT3 levels were obviously decreased with the progression of the disease(P<0.01 and P<0.05). The positive rate of TPOAb in mild group was significantly higher than that in moderate group(OR=9.8,P<0.05). There was no significant difference of the TGAb positive rate among three patient groups(P>0.05). The incidence of subclinical hypothyroidism and clinical hypothyroidism in severe group was significantly higher than that in mild group and in control group(OR=2.5,P<0.05 and OR=9.0,P<0.05;OR=8.0,P<0.01 and OR=43.4,P<0.01). Conclusion Our re-sults indicated that 24-hour urine protein in severe preeclampsia patients has extensive effects on thyroid hormones levels. With the increasing of quantitative 24-hour urinary protein,the level of TSH increased and the FT4 decreased. Thyroid autoantibody positiveness has extensive effects on 24- hour urine protein. Incidence of hypothyroid increased with the increase of quantitative 24-hour urinary protein. 24-hour urinary protein quantitative was a risk factor for hypothyroidism in severe preeclampsia patients. More attention should be paid to the monitoring of 24-hour urinary protein in se-vere preeclampsia patients.

Objective To analyze and evaluate the efficay of split liver transplantation in children.Method From September 2006 to December 2014,210 children were treated with liver transplantation in Tianjin First Central Hospital.The clinical data were retrospectively analyzed and the difference in postoperative survival was compared between the groups.The 210 childrens were categorized into living donor liver transplantation group (183 cases) and split liver transplantation group (27 cases) based on their operation styles.In living group,all donors to recipients were immediate relatives within three generations.In split group,all donors were men,and livers were obtained from no heartbeat donors.Postoperatively,tacrolimus combined a duplex of prednisolone served as immunosuppression scheme.The survival and incidence of complications were observed.Result There was significant difference in the sex ratio between two groups (P＜0.05).The donor liver cold ischemia time was significantly longer in split group than in living group (P＜0.05).The 1-month,6-month,1-year and 2-year overall survival rate in 210 recipients was 99.5％,98.1％,96.2％ and 94.2％ respectively.The median follow-up time in living group and split group was 15.2months and 26.1 months,respectively.The 1-mont,6-month,1-year and 2-year survival rate was 99.5％,96.7％,92.6％ and 74.1 ％ in living group,and 97.8％,96.2％,77.8％ and 74.0％ in split group,respectively (P＜0.05).During the follow-up period,8 cases died (29.6％) in split group (5deaths due to infection and sepsis,and 3 deaths due to multiple organ failure),and 10 cases died (5.5％) in living group (6 deaths due to infection and sepsis,and 4 deaths due to multiple organ failure).Conclusion In the case of strict selection of donors,split liver transplantation can obtain good effect,but the incidence of complications is higher than living donor liver transplantation.Especially,the biliary complications should be prevented and managed actively.

Objective To explore the effectiveness and safety of totally laparoscopic distal gastrectomy (TLDG)and laparoscopically assisted distal gastrectomy (LADG)for gastric cancer.Methods The comparative studies of TLDG and LADG published between 2008 and 2014 were searched from PubMed,EMBASE,Chinese Biomedical Literature Database (CBM),China National Knowledge Infrastructure (CNKI). After screening for inclusion, data extraction,and quality assessment,RevMan 5.3 software was used for Meta-analysis.Results Ten studies of 2 212 patients were included in the Meta-analysis,among whom 930 cases underwent TLDG and 1 282 cases underwent LADG.The results of Meta-analysis indicated that compared with LADG,TLDG had the advantages of less blood loss (WMD= - 20.70,95%CI:- 30.81 - - 10.59,P <0.01),less usage of analgesic (WMD=-0.38,95%CI:-0.74 - -0.02,P =0.04),more retrieved lymph nodes (WMD= 2.98,95%CI:0.71 -5.26,P =0.01).However,the Meta-analysis showed no statistically significant differences in the operation time, postoperative time-to-first flatus and oral intake,postoperative hospital stay,length of proximal resection margin, C reaction protein (CRP)level at postoperative day 1,incidence of overall complications and anastomosis-related complications.Conclusion TLDG is safe and effective with less blood loss, less pain than those of LADG. Moreover,it has comparable results to conventional LADG,with no increase of postoperative complications.

Objective:To evaluate the clinical effects of short fiber ribbon combined with resin bonding technology for the treatment of food impaction between posterior teeth. Methods:98 cases of vertical food impaction between posterior teeth( total of 135 vertical food impaction units) were included. 73 units were treated by short quartz fiber ribbon combined with resin bonding technology( SQFRB) and 63 by resin bonding(RB). 12, 24 and 36 months after restoration, clinical effects were evaluated referring to the Modified United States Public Health Service (USPHS) Criteria, data were statistically analyzed.

Conclusion:Minimally inva-sive restorations using short fiber ribbon combined with resin bonding technology is effective in the treatment of vertical food impaction between posterior teeth.

Objective To observe and discuss the effect of the traditional Chinese drug complex prescription ShensuⅡfrom Xintong Changluo therapeutic principle on renal interstitial fibrosis (RIF) and transforming growth factor-β1 (TGF-β1) expresssion in focal segmental glomerulosclerosis (FSGS) model rats. Methods Forty-eight healthy male SD rats were randomly divided into control group (n=12) and modeling group (n=36). Rats of modeling group were injected by doxorubicin hydrochoride for FSGS model. Rats of modeling group were sub-divided into model group, benazepril group and TCM group randomly. In 12 weeks, TCM group was given by intragastric administration of ShensuⅡ(3.5 g/100 g), benazepril group was given by intragastric administration of benazepril suspension (0.33 mg/100 g), control group and model group were given by intragastric administration of same volume of saline. HE/Masson staining was used to observe changes of tubulointerstitial pathomorphology. The degree of injury and fibrosis was measured. The expressions of fibronectin (FN) and TGF-β1 were detected by immunohistochemical SP method. Results The process of renal interstitial fibrosis was slower in FSGS rats of TCM group. Renal interstitial pathological index was 1.51 ± 0.80 in TCM group, which was lower than that of model group (2.18 ± 0.38) and benazepril group (1.79 ± 0.24). The index of renal interstitial fibrosis was 2.39 ± 0.13 in TCM group, which was lower than that of model group (3.11 ± 0.25) and benazepril group (2.80 ± 0.41). The relative expression of FN in renal interstitial was 14.19 ± 3.06 in TCM group, which was lower than that of model group (21.25 ± 3.31) and benazepril group (18.51±2.29). The relative expression of TGF-β1 in renal interstitial was 2.64±0.21 in TCM group, which was lower than that of model group (6.02 ± 0.12) and benazepril group (3.79 ± 0.46). All the differences were statistically significant (P<0.05). Conclusion Xintong Changluo complex prescription ShensuⅡcan reduce the process of renal interstitial fibrosis in FSGS model rats, which may be related with the inhibiting expression of TGF-β1.
