Objective To explore the clinical feature of Kimura disease complicated with nephrotic syndrome in children. Methods The clinical data from 4 children with Kimura disease complicated with nephrotic syndrome were retrospectively analyzed. Results In all of the 4 male children, level of serum IgE was increased but level of eosinophils was not increased in peripheral blood. The renal pathological manifestations were different among them. Two cases had acute tubular injury, one case had pathological changes in repeated renal biopsy, and one case had a little of eosinophils infiltration in renal interstitium. All of them were sensitive to oral hormone treatment. Except that one case had no relapse yet in short follow-up period, the other 3 cases had relapsed and all manifested as positive urinary protein without lymphadenectasis. The 3 cases with recurrence were treated by combined immunosuppressive agents, the palindromia of two cases were reduced which were combined with tacrolimus. Conclusion The Kimura disease complicated with nephrotic syndrome in children has a long course and different renal pathological manifestations. It is sensitive to hormone treatment but easy to relapse, and the treatment should be combined with immunosuppressive therapy. Tacrolimus may have the effect on reducing relapse and delaying the progress of renal pathology.

Purpose: To observe therapeutic effect of acupuncture plus Methadone on improvement of heroin withdrawal syndrome. Methods: Sixty cases of heroin dependence patients were divided into the treatment group and the control group. The treatment group was given acupuncture plus Methadone, and the control group was treated with Methadone.Results: The score of the withdrawal symptoms was lower in the treatment group than in the control group (P ＜ 0.05). The improvement of withdrawal symptoms was significantly better in the treatment group than in the control group (P＜ 0.05). Conclusion: Acupuncture plus Methadone can significantly improve heroin withdrawal syndrome.

Objective To investigate the efficacy of breast tissue flap cohesive treatment after breast augmentation injection mixture dis-placed.Methods A total of 78 patients with breast augmentation injection mixture polyacrylamide hydrogel(PAAG)shift in our hospital from January 2006 to March 2014 were divided into two groups according to different surgical methods,39 cases with the material shifted to abdominal wall in control group were treated by taking the cleaning operation to scrape residual cavity,39 patients in observation recieved new breast tissue flap design local treatment of breast fistula closed chest and abdominal wall channel after surgical elimination of the same abdom-inal wall cavities.Results The PAAG extensive deposition in the breast tissue,armpits,chest wall clearance were formed fistula communica-tion.The secretions of patients treated with tissue flap decreased 82%,the lacunar lesions reduced 80% after 2 weeks,while patients without tissue flap,the drain reduced 46%,the lesion size reduced 45%,the difference between the two groups was significant(P <0.01).The heal-ing rate of tissue flap group was higher than that of conventional group after 4 weeks.Conclusion The PAAG mixture shifting formed fistula communication in the abdominal wall is the main reason of the mass flow and a huge cavity.Flap can significantly promote abdominal wall fis-tula healing.

Objective To investigate the clinical effect of cosmetic suture technique applied in organs of facial emergency surgery. Methods There were 25 patients who were admitted in our hospital from August 2009 to December 2013. After anatomical reduction and functional restoration, they were given surgery with cosmetic suture technique on the base of debridement. Results All of the patients a-chieved good surgical result, the satisfaction is 100%. After the first stage of operation, 23 patients of them were of no obvious scar and good function recovery. The other 2 patiens also got good effects after secondary surgery. Conclusion Cosmetic suture technique pay attaintion to anatomical and functional restoration. It is of equisite technique, slight injury, less scar after operation and it can maximumly get close to the normal tissue structures and achieve the objective of beauty.

Objective To explore the distribution of the liquid food in the stomach of patients with postprandial distress syndrome (PDS)-predominated functional dyspepsia (FD)and the mechanism of its gastric dynamic dysfunction.Methods Fifty-two patients with PDS and 18 healthy volunteers underwent gastric emptying examination with ultrasound scanner provided.The proximal and distal gastric area and volume,area and volume ratio of proximal and distal gastric as well as emptying rate of proximal and distal gastric were calculated at fasting,maximum satiety,30 min,60 min,90 min and 120 min after meal. Student′s t test andχ2 test were performed for statistical analysis.Results Proximal gastric volume of PDS group at the time of fasting and 120 min after meal were (9.06±7.88)and (24.72±24.02)cm3 ,which were larger than those of healthy control group ((5 .96 ± 2.13 )cm3 ,(19.48 ± 12.32 )cm3 ),and the differences were statistically significant (t=-1 .637 and -0.875 ,both P <0.05).Ratio of proximal and distal gastric area at maximum satiety in PDS group was 1 .63±0.42 and that in healthy control group was 2.33±0.63,and the difference was statistically significant (t =5 .044,P <0.05 ).Ratio of proximal and
distal gastric volume in PDS group and healthy group at fasting was 0.60 ± 0.38 and 0.46 ± 0.19, respectively,that at maximum satiety was in PDS group and healthy group 0.91 ±0.27,1 .30 ±0.48, respectively,and the differences were statistically significant (t = - 1 .505 and 3.970,both P <0.05). The emptying rates of proximal stomach of PDS group at 30 min and 90 min postprandial were (28.10 ± 25 .03)% and (68.80±16.14)%,respectively,those of healthy control group were (34.97 ±14.41 )%and (75 .86 ±9.86)%,and the differences were statistically significant (t =1 .087 and 1 .718,both P <0.05).There was no statistically significant difference in emptying rate of distal stomach between two groups (all P > 0.05 ).Conclusions The volume of distal stomach was larger than that of proximal stomach in PDS patients at maximum satiety in liquid food distribution,which may be the cause of decreasing emptying rate of proximal stomach.And proximal stomach dominated gastric motility in PDS patients.

Objective:To investigate the clinical features of children with kidney diseases who developed posterior reversible encephalopathy syndrome (PRES), explore the risk factors of PRES in these children, improve the understanding of the diseases, and help early diagnosis and effective treatment of the diseases.Methods:The clinical manifestations, laboratory inspection results, magnetic resonance imaging(MRI) material as well as the prognosis of 10 children with kidney diseases complicated by PRES who were admitted to the Department of Nephrology, Xi′an Children′s Hospital from November 2016 to August 2018 were analyzed retrospectively.Results:A total of 10 children were recruited, including 1 boy and 9 girls, with the onset age ranging from 4 years and 3 months to 13 years [(8.53±3.09) years]. The diagnosed kidney diseases in these patients were primary nephritic syndrome (6 cases), lupus nephritis (1 case), Hepatitis B-related nephritis (1 case), polyarteritis (1 case) and hemorrhagic fever with renal syndrome (1 case). Eight children received corticosteroids and 4 of them received other immunosuppressants simultaneously.Nine children suffered from the infections.All of them had acute onset, and the main symptoms were hypertension (10/10 cases, 100.0%), headache and dizziness (5/10 cases, 50.0%), nausea and vomiting (5/10 cases, 50.0%), visual disturbance (3/10 cases, 30.0%) and convulsions by the ways of seizures definitely (9/10 cases, 90.0%). There was nothing positive in the examinations of the nervous system and fundus.Computer tomography examinations of 9 cases showed nonspecific low-density foci.The cranial MRI scan showed abnormal signals on the cerebral cortex of frontal lobe, parietal lobe and occipital lobe in all these 10 cases.The hyperintensities were observed on the fluid-attenuated inversion recovery sequences of all the 10 cases.Slight hyperintensities on diffusion-weighted images of 4 cases indicated that PRES progressed from reversible angiogenic edema to irreversible cytotoxic edema, meaning a poor prognosis.After blood purification treatment and reducing intracranial pressure, these 4 cases recovered.After timely treatment upon PRES diagnosis, patients had no recurrence and showed a good outcome.Conclusions:Children with kidney diseases and PRES also suffer from hypertension, and the treatment with immunosuppressive agents may precede the occurrence of PRES.Cranial MRI is important for the diagnosis of PRES.
