The incidence of hypokalemia and periodic paralysis was retrospectively analyzed in 1225patients with hyperthyroidism. The results showed that 104 patients with hyperthyroidism (8.5%)had hypokalemia, and 82. 7% cases were women, with the potassium levels of 3.10 - 3.42 mmol/L. Periodic paralysis occurred in 60 patients (4. 9% ) and 96. 7% cases were men; 93.3% patients had the potassium levels less than 3. 0 mmol/L. Hypokalemia and periodic paralysis were alleviated after the control of hyperthyroidism.

Objective To study the 2244G→A, 2299 A→G single nucleotide polymorphism (SNP) in the 5' regulatory regions of Toll-like receptor 4 (TLR4) in patients with Gram negative bacteria infection in Shenzhen locality, and to discuss the occurrence, course and prognosis of patients with sepsis. Method Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to detect the genotype of TLR4. After the whole blood DNA of patient was extracted and PCR was amplified, the products were 500bp and 599 bp, and were cut by endonuclease Mae Ⅱ and Sph Ⅰ respectively to determine the SNP 2244G→A and 2299 A→G in TLR4. These two kinds of allele frequencies were statistically calculated in all patients. In the meantime, the incidence of septic shock, average hospitalized days, cost and prognosis of all patients were recorded. Statistical analysis was performed with SPSS version 16 software. ANOVA was used for comparison among multiple groups, and t -test and Sighed rank test were used for paired comparison. Results The 2299 and 2244 sites in the 5' regulatory regions of TLR4 gene of patients with Gram negative bacteria infection in Shenzhen locality had various degrees of changes in single nucleotide. Compared with the documented data from Chinese people in general, there was a significant difference in 2299A→G genotype frequency in residents of Shenzhen locality ( P < 0.05). But there were no statistically significant difference in mortality, incidence of septic shock, average days of ICU stay or ICU cost between TLR4 SNP positive and negative groups of patients. Conclusions There is a wide range of genetic variation in the 2299 and 2244 sites in the 5' regulatory regions of TLR4 among citizens of Shenzhen locality with unique distribution. The 2299A→G genotype frequency probably has differences in distribution and population. The pathogenesis and the prognostic factors of sepsis are complicated, whereas the gene polymorphism may be just one of the factors affecting the prognosis of patients with Gram negative bacteria infection.

Objective To investigate the clinical performance of fiber post restorations in elderly patients with residual root and crown and to analyze the factors affecting the clinical success rate.Methods A total of 66 elderly patients requiring post restoration were selected.They were randomly divided into two groups:the observation group (n=33,restored with fiber post-resin cores) and the control group (n=33,restored with cast metal post-cores).All patients were rechecked 1 year and 2years after the restoration.The clinical efficacy and the failure types were recorded.The differences in clinical performance between the 2 groups were compared by using Fisher's exact test.Results The differences in the gingival index and periodontal index in the 2 groups between the experimental teeth and the control teeth were zero.There were no significant differences in dental morphology,root canal treatment failure,tooth color matching and marginal coloration between the 2 groups (all P＞0.05).1 case with post debonding and 1 case with fiber post fracture were found in the observation group and 1 case with marginal coloration was found in control group.There was no significant difference in clinical success rate between the 2 groups (93.94％ vs.96.97％,P＞0.05).Conclusions The clinical success rate in fiber post-resin core restoration is the same as in cast metal post-cores restoration in elderly patients.

Objective To explore the medium effect of social support in process of attachment styles and coping styles on criminal juveniles and adolescents with mood disorders.Methods The survey used in the research included Experiences of Close Relationships Inventory (ECR),Social Support Revalued Scale(SSRS) and Coping Style Questionnaire(CSQ) conducted by three groups:177 criminal juveniles,80 adolescents with mood disorders and 163 normal teenagers.Results Firstly,there were significant differences in the avoidant attachment,attachment anxiety,objective support,subjective support,utilization of support,solving problem,rationalization,self-accusation and retreat among three groups (F=7.902,8.047,59.009,19.248,5.304,7.596,10.652,6.699,11.009;P＜0.05).Secondly,attachment avoidance had significant negative correlation with both utilization of support and help seeking behaviors in the group of mood disorders (r =-0.470,-0.350; P＜ 0.01).Similarly,avoidant attachment had significant negative correlation with both subjective support and utilization of support respectively (r=-0.232,-0.235 ; P＜0.01) in the group of criminal juveniles.The subjective support had significant positive correlation with solving problem (r=0.272,P＜0.01) and as well as the utilization of support with both solving problem and help seeking behaviors (r=0.258,0.424; P＜ 0.01).Attachment anxiety had significant negative correlation with objective support and had significant positive correlation with self-accusation respectively (r=-0.253,0.300;P＜0.01).Finally,utilization of support as a medium completely effect on the process of avoidant attachment and help seeking behaviors in the group of mood disorder and criminal juveniles.Moreover,subjective support and utilization of support as medium both affected a part in the process of avoidant attachment and solving problem for the group of criminal juveniles.Conclusion First,both adolescents with mood disorders and criminal juveniles have unsafe attachment mode,which are lacked social support and easy to take negative coping styles.Yet,the level of attachment avoidance and subjective support of criminal juveniles was found different compared to teenagers with mood disorder.Second,the attachment styles for both adolescents with mood disorders and criminal juveniles have impact on coping styles by the means of social support,but there were slightly different way.

Objective To investigate the expression and role of β-catenin in small-for-size liver grafts during early stage of liver regeneration after liver transplantation in rats.Method The livers of male Sprague-Dawley rats were reduced to 30％ or 50％ of their original sizes and transplanted.The experiment was divided into 3 groups:small-for-size graft group (SSG),half-size graft group (HSG) and sham-operated group.Liver samples were harvested at various time points after transplantation (n =6 per time point) for Western blotting and immunohistochemistry.Six rats in each group were sacrificed at 3rd day after liver transplantation for estimating liver regeneration rate.Result Liver regeneration rate in SSG group was lower than that in HSG group.The expression of β-catenin was down-regulated in liver graft of both groups after being stored in cold Ringer solution for 2 h.The expression of β-catenin was significant up-regulated in HSG group from 5 min to 12 h after operation,while the down-regulated expression of β-catenin was persisted in SSG group at 5 min after operation,and mildly increased expression of β-catenin occurred at 2 h and 6 h,which was significantly lower than that in HSG group at the corresponding time points.The expression of active-β-catenin was low in each group before transplantation.Significant expression of active-β-catenin was found at 5 min in HSG group and persisted until 12 h after operation,mildly increased expression of active-β-catenin in SSG group was only found at 2 h,which was lower than that in HSG group at the same time points.Immunohistochemical staining revealed that β-catenin was mainly expressed on the hepatocyte membrane and in cytoplasm in the sham-operative group,many hepatocytes exhibited nuclear localization of β-catenin in HSG group from 5 min to 24 h,while only some hepatocytes exhibited nuclear localization of β-catenin in SSG group.The expression of Cyclin D1 in SSG group was significantly lower than that in HSG group,which was similar to the expression of C-Myc.Conclusion Attenuated activation of Wnt/β-catenin signaling and down-regulated expression of target genes during early regeneration of small-for-size liver grafts may be involved in the inhibition of liver regeneration of small for size liver grafts.

Objective To investigate the trend of liver function changes in untreated adult patients with Graves’ disease in China, and to analyze the associated factors. Methods Patients with newly diagnosed as well as recurrent Graves’ disease from January 2006 to August 2014 were enrolled. They were over 18 years old and did not receive any treatments, Examination of liver function, thyroid function, and thyroid related antibodies as well as tests regarding virus hepatitis were performed. Results A total of 1 254 patients were enrolled. 33 patients with virus hepatitis were ruled out. Ultimately, 1 221 patients matched the criteria of our trial, with 347 males and 874 females [(39. 3 ± 9. 5) year old]. After inclusion, they were assigned to 2 groups according to their liver function results(605 in normal group and 616 in abnormal group). Compared to normal group, patients in the abnormal group were older [(40. 1 ± 9. 2 vs 38. 5 ± 8. 7) year old, P<0. 05] and with higher proportion of females(81. 8% vs 61. 2% , P<0. 05). Regarding the thyroid function and related antibody tests, some patients yielded results that were extremely high so as to exceed the upper limit of the normal range. These patients were more frequently seen in the group with abnormal liver function. The patients whose thyroid function parameters exceeded the upper limit had higher level of alanine aminotransferase[ALT,(37. 69 ± 7. 51 vs 31. 90 ± 5. 95) U/ L, P<0. 05], aspartate aminotransferase[AST, (31. 97 ± 5. 09 vs 27. 88 ± 3. 82) U/ L, P<0. 05], direct bilirubin[DBiL, (5. 58 ± 0. 77 vs 4. 54 ± 0. 71) μmol/ L, P<0. 05]than the group whose thyroid function on the detected range. In the patients with all results detected, patients in abnormal liver function group had higher level of triiodthyronine[T3 , (5. 42 ± 0. 29 vs 4. 94 ± 0. 33) nmol/ L, P<0. 05], thyroxin[T4 ,(217. 53 ±14. 32 vs 204. 22 ±13. 54) nmol/ L, P<0. 05], free triiodthyronine[FT3 ,(15. 88 ± 2. 86 vs 14. 48 ±4. 83) pmol/ L, P<0. 05], free thyroxin[FT4 ,(48. 91 ±8. 45 vs 42. 95 ±6. 14) pmol/ L, P<0. 05], thyroid peroxidase antibody[ TPOAb, (402. 75 ± 89. 99 vs 210. 70 ± 44. 63) IU/ ml, P < 0. 05] and thyrotrophin receptor antibody[TRAb,(14. 08 ± 5. 24 vs 9. 04 ± 2. 58) IU/ L, P<0. 05]. Multivariate logistic regression analysis revealed that patients’ age(OR=0. 98, 95% CI 0. 97-0. 99), gender(OR=0. 94, 95% CI 0. 91-0. 97), level of FT4 (OR=3. 08, 95% CI 2. 19-4. 32), TPOAb(OR = 0. 98, 95% CI 0. 97-0. 99), and TRAb(OR = 1. 07, 95% CI 1. 01-1. 12) were independent risk factors of their liver dysfunction. Conclusion Graves’ disease may lead to liver dysfunction, which is much more common and severe in elder and female patients, as well as patients who are suffering from hyperthyroidism and raised level of thyroid related antibodies.

ObjectiveTo investigate the difference in the outcomes in patients with acute anterior circulation stroke having achieved the Thrombolysis in Cerebral Infarction (TICI) 2b and TICI 3 recanalization after mechanical thrombectomy.MethodsThe patients with acute anterior circulation stroke having achieved successful recanalization after mechanical thrombectomy were enrolled retrospectively.They were divided into TICI 2b (almost complete recanalization) group and TICI 3 (complete recanalization) group.The good outcome was defined as the modified Rankin Scale score 0-2 at 3 months after onset.ResultsA total of 83 patients were enrolled in the study, including 38 patients (45.8%) with TICI 2b and 45 (54.2%) with TICI 3;49 (59.0%) had good outcome, and 34 (40.9%) had poor outcome.The good outcome rate in the TICI 3 group was significantly higher than that in the TICI 2b group (68.9% vs.47.4%;χ2=3.946, P=0.047).After adjusting for age, hypertension, diabetes, baseline systolic blood pressure, triglyceride, intravenous thrombolysis, and ASITN/SIR collateral grades, TICI 3 was an independent predictor for good outcome at 3 months after onset (odds ratio [OR] 3.759, 95% confidence interval [CI] 1.098-12.871;P=0.035), while the higher baseline National Institutes of Health Stroke Scale score (OR 0.820, 95% CI 0.715-0.941;P=0.005) and higher fasting glucose (OR 0.610, 95% CI 0.410-0.906;P=0.014) were the independent predictors for poor outcome at 3 months after onset.ConclusionsThere are difference in the outcomes in patients with successful recanalization in anterior circulation stroke treated with mechanical thrombectomy.The outcome is substantially better in TICI 3 than TICI 2b patients.

Objective To compare the efficacies of 4 risk models (THRIVE[Totaled Health Risks in Vascular Events],MSS[Multicenter Stroke Survey],HIAT[Houston Intra-Arterial Therapy],and GRASPS[Glucose at presentation,Race,Age,Sex,Systolic blood pressure,Severity of stroke at presentation]) in predicting intracranial hemorrhage and poor outcomes in acute anterior circulation ischemic stroke after mechanical thrombectomy.Methods From May 2013 to March 2016,153 consecutive patients with acute anterior circulation vascular occlusion conducted mechanical thrombectomy within 6 hours after onset and admitted to the Departments of Neurology,Jinling Hospital,Nanjing University School of Medicine and Zhongshan Hospital,Xiamen University were enrolled prospectively.Logistic regression analysis and the area under the receiver operating characteristic (ROC) curve (AUC) were used to investigate the efficacies of 4 risk models (the THRIVE,MSS,HIAT,and GRASPS scores) for predicting intracerebral hemorrhage (including any intracranial hemorrhage events and symptomatic intracranial hemorrhage) and poor outcomes (including 90 d all-cause death and modified Rankin Scale[mRS] score≥3) in acute anterior circulation ischemic stroke after mechanical thrombectomy.Results The MSS score (AUC 0.639,95%CI 0.548-0.730,P=0.004) and GRASPS score (AUC 0.616,95%CI 0.525-0.706,P=0.017) could predict any intracranial hemorrhage events,but the predictive accuracy was low.They had the predictive value for death within 90 d after mechanical thrombectomy,and the GRASPS score (AUC 0.783,95%CI 0.706-0.860,P<0.001) had the moderate predictive accuracy,and the AUC of the other 3 models was all<0.7,the predictive accuracy was low.The models could predict the poor prognosis at 90 d (90 d mRS≥3).The AUCs of both the GRASPS score and THRIVE score were >0.7.The AUC of GRASPS score was the largest (AUC 0.782,95%CI 0.708-0.885,P<0.01).Both had moderate predictive accuracy.Conclusion The GRASPS score had a better clinical predictive value for all-cause death and poor prognosis within 90 d after mechanical thrombectomy.The THRIVE score had a better clinical predictive value for poor prognosis at 90 d.The 4 models predictive value for intracranial hemorrhage events after mechanical thrombectomy should be further examined.

Objective To induce bone marrow mesenchymal stem cells (BMSCs) differentiated into hepatocyte-like cells with rebirth liver tissue lixivium of mouse in vitro.Methods Mouse BMSCs were isolated and directionally induced with rebirth liver tissue lixivium of mouse 36 h after partial hepatectomy (PH). The morphology of cells was observed under an invert microscope, and the characteristics of differentiated cells was identified by immunofluorescence test.Results 7 days after induced by liver lixivium, the spindle shaped BMSCs became round and resembled hepatocyte-like cells. 1～2 weeks later, the differentiated cells expressed albumin, CK8 and CK18, which were known as characteristic markers of the hepatocyte.Conclusion BMSCs of mouse can be differentiated into hepatocyte-like cells under induction of liver tissue lixivium of mouse.
