OBJECTIVE:To observe therapeutic efficacies and safety of diltiazem combined with ciclosporine in the treatment of nephrotic syndrome complicated with acute renal injury. METHODS:A total of 66 patients with nephrotic syndrome and cute kid-ney injury were randomly divided into control group(30 cases)and observation group(36 cases). Control group was given routine treatment;observation group was additionally given Diltiazem hydrochloride tablet 5 mg orally,twice a day,and Ciclosporin soft capsules 1.5 mg/(kg·d)orally,twice a day. Treatment course of 2 groups lasted for 20 d. Clinical efficacies of 2 groups were ob-served. The serum creatinine and kidney injury molecule 1(KIM-1),24 h urine volume,24 h urine protein levels,AKI classifica-tion,follow-up and recurrence were observed before and after treatment as well as the occurrence of ADR. RESULTS:The remis-sion rate of observation group was significantly higher than that of control group,and recurrence rate was significantly lower than control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in the serum creatinine levels,KIM-1,24 h urine pratein,24 h urine and AKI classification between 2 groups (P>0.05). After 2 weeks and 1 month of treatment of observatiom groups,and after 1 month of treatment of control group,serum creatinine levels,KIM-1 and 24 h urine protein of observation group were significantly lower than before treatment,and the observation group was significantly lower than the control group;24 h urine and the ratio of gradeⅠby AKI classification were significantly more than before treatment,and the observation group was significantly more than the control group,with statistical significance(P<0.05). Follow-up rate in 2 groups were 100%,and there was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Based on routine treatment,diltiazem combined with ciclosporin shows significant therapeutic efficacy in the treatment of nephrotic syn-drome and acute renal injury with good safety.

Objective To investigate the effect of low 1evel laser treatment (LLLT) on periodontal clinical index,high-sensitivity C-reactive protein (hs-CRP) and metabolic control in patients of type 2 diabetes mellitus combined chronic peridontitis.Methods Nighty patients with type 2 diabetes combined chronic peridontitis were divided into three groups:initial periodontal therapy (group A),initial therapy combined with LLLT (group B) and control group (group C).The periodontal clinical parameters including periodontal probing depth (PD),clinical attachment loss (CAL),sulcus bleeding index (SBI),hs-CRP,HbA1c and fasting blood glucose (FBG) were tested before and at three months after therapy.Results The periodontal clinical parameters (PD,CAL,SBI) and hsCRP in group A and B improved significantly compared with that of group C after therapy (P＜0.05),with group B had more significant difference (P＜0.01).For the levels of HbA1c and FPG,group A and B showed downtrend,and more obvious outcome was detected in group B (P＜0.05).Conclusions LLLT can effectively improve periodontal status,hs-CRP levels and metabolic control of patients with type 2 diabetes combined with chronic peridontitis,and thus to prevent the occurrence of diabetes complications.

Objective The purpose of this study was to explore the efficacy of low level laser treatment (LLLT) combined with initial periodontal therapy in treating chronic periodontits.Methods Eighteen patients with chronic periodontitis were randomly treated in a spit-mouth design with combination of laser (808 nm,80 mW) treatment with scaling and root planing (experimental) or with scaling and root planing alone (contol) after OHI and supragingival cleaning.Clinical parameters of sulcus bleeding index (SBI),periodontal probing depth (PD) and clinical attachment loss (CAL) of both sides were recorded and gingival crevicular fluid samples were collected at baseline and 1,4,12 weeks after the treatment.GCF samples were analyzed for b-FGF,IL-1β,IL-8 level using ELISA assay.Results For the change of SBI and PD,only SBI in the experimental group experienced significant reduction (P＜0.05) at 1 week compared with baseline (P＜0.05),and the reduction in both groups were statistically significant (P＜0.05) at 4 weeks.The same situation occurred while both experimental groups made more significant difference (P＜0.01) at 12 weeks.The reduction of SBI was obvious in both groups when the PD was more than 6 mm.For CAL,the experimental group showed signs of improvement (P＜0.05) at 4 weeks; both groups indicated improvement (P＜0.05),while the experimental was more significant (P＜0.01) at 12 weeks.For the levels of b-FGF,it showed steady rise after treatment in experimental group,while it went up to the baseline after falling in control group.At 12 weeks,there were statistical significance of differences between two groups (P＜0.05).The changes of IL-1β and IL-8,in the experimental group showed better results than that in control group,while the difference between two groups was not significant (P＞0.05).Conclusion LLLI can accelerate the healing of periodontal tissue by reducing the SBI,decreasing the PD,improving the CAL and increasing levels of b-FGF in the GCF of the patients.

Objective To explore the effect of preservation of inclined fractured permanent molars by transverse fixation with screw post,and provide a practical method for reserving the inclined fractured permanent molars.Methods Clinical data of 50 patients with inclined fractured permanent molars by transverse fixation with screw post in the Department of Stomatology of Tianjin First Central Hospital between January 2010 to December 2011 were reviewed retrospectively.After fixing the crown with steel-wire binding and root canal treatment,the molars were drilled a hole buccolingually and placed screw post.The flowable light-curing composite resin was used to seal the crack and bond screw post to prevent the relative movement.All treated molars were restored with full crown.All patients were followed up for 10-60 months.The therapeutic effects were observed.Results After 5 year-follow-up,41 cases were cured completely,6 cases were cured clinically,and 3 cases failed treatment.Conclusion The transverse fixation with screw post and bonding technique can preserve the inclined fractured molars to gain chewing function and avoid or reduce the extraction of affected teeth,which provides a better restoration effect.

Objective To compare the differences of personality in patients with depression between Uighurs and Han Chinese.Method Hospitalized depressed patients were selected including 44 cases of Uygur people,73 cases of Han people and Han people with normal control 41 cases.Using Minnesota Multiphasic Per-sonality Inventory(MMPI), Eysenck Personality Questionnai(EPQ) and Cattell's 16 Personality Factor (16PF) to make the survey.Results In MMPI : Uighur depression group's factors F,Hs, D,Hy,Pt,Pa and Sc's T score were all higher than 70,and Han depression group' s factors Hs, D,Hy,and T score of Pa were all higher than 70.Only F (76.98±16.01 vs 67.16±13.51, P＜0.01), Pt(72.09± 14.22 vs 66.82± 11.12, P＜0.05) and Sc (73.43± 13.02 vs 68.62± 11.14, P＜0.05) had statistically significant differences between the two groups.Comparing Han depression group with Han normal control group,only Pd score was not significantly different,the other nine scales were statistically significant (P＜0.01).In EPQ: comparing Uighur depression group with Han depression group,the 4 kinds of scale (extroversion, psychoticism, neuroticism and conceal) differences were not statistically significant (P＞0.05).And Han depression group compared with the Han control group, four scales were statistically significant differences (P＜0.01).In 16 PF: comparing Uighur depression group with Han depression group, only the wisdom of B (P＜0.01) and the independence of the Q2 (P＜0.05) between the two groups were statistically siguificant,other personality dimensions had no significant difference (P＞0.05).Comparing Han depression group with Han normal control group, the factors of gregariousness A, stability C, excitability D,perseverance G, boldness H, sensitivity I,skeptical L,anxiety and O,self-discipline Q3,tension Q4 (P＜0.0l) and experimental Q 1 (P＜0.05) differences were statistically significant, and the factors of Wisdom of B, aggressiveness E, fantasy M, sophisticated sex N, independence Q2 were not statistically significant (P＞0.05).Conclusion The personality model of depression between the Uygur and Han nationality has the consistency of national culture,and differences with normal people.Prompt Uygur and han depression may have a common characteristic of pathological personality model.Uighur and han ethnic differences in national culture and personality is the character of diversity,is not a Uighur and Han the pathological basis of personality of depression.
