Objective To explore the dead reasons and related factors of acute leakemia(AL)in children.Methods The clinical data of 42 dead cases of children with AL,who were admitted to Guangzhou Children's Hospital between Jan.1999 and Mar.2007 were reviewed.Nineteen cases were boys,23 cases were girls;the aging from 4 months to 12 years old and 5 months.Of 42 children,21 cases were acute lymphoblastic leukemia(ALL),18 cases were acute myeloid leukemia(AML),3 cases were unclassified AL.Results Ten out of 12 early-dead cases died of bleeding.Among 30 cases who received chemotherapy,4 cases died of bleeding,others of myelosuppression combined with infection,14 of whom died from sepsis,3 cases with fungal infection,1 case with virus infection,4 cases with unknown pathogens.Sixteen children relapsed among those who got remission,half of them relapsed within 1 year since diagnosed.Treatment-related mortality(TRM)was 90%(27 out of 30 cases).The main causes of TRM were infection and hemorrhage.Hyperleukocytosis and bleeding were 2 risk factors related to early death in new-diagnosed children.Conclusions More emphasizes should be put on bleeding tendency during early treatment in children with AL and treatment of infection complications during induction chemotherapy to reduce TRM.

Objective To investigate the technique of drain air, cryotherapy, and explant (DACE) of operation for superior bullous retinal detachment (SBRD). Methods In the DACE procedure, drainage and air or balanced salt soultion (BSS) injection were carried out first, with the intention of flattening the retina before localization of retinal hole, cryotherapy out of choroid and scleral buckling. Results In 42 SBRD eyes, 40 underwent the operation with DACE technique. In 23 eyes injected with BSS instead of air, 5 should be injected air due to no avail for flattening deeply retinal detachment, and 1 needed scleral buckling due to new retinal tear after DACE procedure two weeks. During the follow up, all retinae attached. Conclusions The DACE technique is very useful and effective in upper ballooned retinal detachment due to single hole or breaks localized in small area between the 10 and 2 o′clock meridiant. BSS instead of air injection can eliminate the difficulty of observation of retinal breaks from the presence of air in some cases.

Objective To compare the mRNA expressions of interleukin (IL)-17 and IL-23 in peripheral blood of patients with psoriasis vulgaris versus healthy individuals,assess the relationship of these parameters with psoriasis area and severity index (PASI) score,and to investigate the therapeutic mechanisms of total glucosides of peony (TGP) for psoriasis vulgaris.Methods Fifty patients with psoriasis vulgaris and 40 healthy individuals were enrolled in this study.Of these patients,42 were treated with TGP of 600-900 mg twice a day for 8 weeks.Blood samples were obtained from all the healthy individuals,50 patients before treatment,42 patients after 4-week treatment,and 23 patients after 8-week treatment.Real-time fluorescence-based quantitative reverse transcription PCR (RT-PCR) was used to determine the mRNA expression levels of IL-17 and IL-23 in the blood samples.The severity of psoriasis was evaluated using PASI score before and after the treatment.Statistical analysis was done by t test,rank sum test,and Pearson correlation analysis using the SPSS16.0 software.Results The IL-17 and IL-23 mRNA expression levels (given in △Ct value) in the patients before treatment were significantly higher than those in the healthy controls (IL-17,-5.32 ± 0.80 vs.2.79 ± 0.76,t =47.71,P ＜ 0.05; IL-23,-5.43 ± 0.68 vs.-3.77 ± 0.86,t =10.38,P ＜ 0.05),and positively correlated with the PASI score (r =0.61,0.52 respectively,both P ＜ 0.05).A significant decrease was observed in the mRNA expression levels of IL-17 and IL-23 as well as PASI score in the 42 patients after 4-week treatment with TGP compared with those before treatment(IL-17,-2.24 ± 0.61 vs.-5.30 ± 0.78,t =20.40,P ＜ 0.05; IL-23,-1.97 ± 0.74 vs.-5.44 ± 0.68,t =21.69,P ＜ 0.05; PASI,5.8 ± 2.7 vs.9.4 ± 4.2,t =4.68,P ＜ 0.05),and in the 23 patients after 8-week treatment compared with those after 4-wek treatment(IL-17,-1.51 ± 0.78 vs.-2.21 ± 0.59,t =3.50,P ＜ 0.05; IL-23,-1.27 ± 0.81 vs.-1.89 ± 0.72,t =2.70,P＜ 0.05; PASI,3.8 ± 1.8 vs.7.3 ± 2.5,t =5.47,P＜ 0.05).Conclusions It seems that both IL-17 and IL-23 are involved in the pathogenesis of psoriasis vulgaris,and TGP treatment can reduce the mRNA expression levels of IL-17 and IL-23 as well as PASI score in patients with psoriasis vulgaris.

Objective To investigate the apathy and neuropsychological characteristics of newly diagnosed Parkinson's disease (PD) patients.Methods Eighty-two newly diagnosed PD patients and 30 matched healthy controls by age,sex and education level were recruited in the present study.Apathy was assessed using Apathy Evaluation Scale (AES) and related factors,including age,sex,education level and disease duration were simultaneously evaluated.Unified Parkinson's Disease Rating Scale (UPDRS),Hamilton Depression Rating Scale (HAMD),as well as Montreal Cognitive Assessment (MoCA) were employed in order to respectively evaluate the motor function,depression and cognition.Results The AES scores in the PD patients were significantly higher when compared to the healthy controls.The prevalence of apathy and depression in the PD patients was 51.2％ (42/82) and 19.5％ (16/82),respectively.There were no statistically significant differences in age,sex,education level,UPDRS-Ⅱ/Ⅲ scores and MoCA scores between apathy (n =42) and no-apathy (n =40) PD patients (P ＞ 0.05),while the statistically significant difference in HAMD scores between apathy (n =42) and no-apathy (n =40) PD patients was shown (the HAMD scores of apathy PD patients were 10.61 ± 3.30,the HAMD scores of no-apathy PD patients were 5.96 ± 1.90,t =7.87,P ＜ 0.05).The correlation analysis indicated that there were no correlations between AES scores and the related factors,including age,education level,disease duration and UPDRS-Ⅱ / Ⅲ scores,but AES scores were positively correlated with HAMD scores.Conclusion In newly diagnosed PD patients,the apathy is independent of depression,motor dysfunction,as well as cognitive impairment,which may be an early signal for PD.

The clinical data of patients with hypoparathyroidism accompanied by elevated and normal muscle enzymes were analyzed retrospectively.The results showed that there were no differences in age,gender,pathogenesis,etiology,and parathormone level between groups with elevated muscle enzyme and normal muscle enzyme.Serum calcium concentration in the group with normal muscle enzyme was within normal range.Serum calcium concentration in the group with elevated muscle enzyme was significantly lower than that in the group with normal muscle enzyme (P＜0.01).As the serum calcium concentration rose,the elevated enzyme level gradually returned to normal range,suggesting that the decrease of serum calcium concentration resulted in the elevated muscle enzyme levels in patients with hypoparathyroidism.

Objective The aim of study is to evaluate the efficacy of a new complementary midurethral sling surgery in treating recurrent or persist female stress urinary incontinence (SUI) after primary Synthetic mid-urethral slings (MUSs).Methods The methods was used in 32 patients who had suffered recurrent or persist SUI patients after primary MUSs during June 2005 and July 2011.Their primary MUSs were:TVT 2 cases,IVS 4 cases,TVT-O 17 cases,TOT 3 cases,T-sling 1case,other MUSs 5 cases.9 cases complained SUI symptoms continued after primary surgery and had no improvement after 6 months following up.23 cases reported SUI symptoms recurrent and aggravated in 6 months after primary operation and had no improvement 1 year after operation.All these patients have been treated with surgery,a trans-vaginal mid-urethral sling on descending pubic ramus.In this study we followed up these patients for one year after this complementary operation and evaluated operating time,blood loss,efficacy and complications.Results In this study the operating time was 41.1±13.1 minutes,blood loss was 70.6±23.8 ml.30 patients kept urinary catheter 6 h after operation and 2 kept urinary catheter 48 h after operation.All patients could micturate after removed urinary catheter and average residual urine was 23.8 ± 21.4 ml (range 0-80 ml).The average in-patients duration was 4.8± 1.1days.SUI symptoms still persisted in two patients after second operation,subjective cure was achieved in 26 patients and the symptoms obviously improved in 4 patients when they left hospital.The efficient rate was 93.8％ (30/32) left hospital and after 3 months,93.3％ (28/30) after 6 months and 86.2％ (25/29) after 1 year.There were 2 cases of recurrence and 1 case of mesh erosion after 1 year,no other operative complications were reported.Conclusions Our study found that it is a efficient operation to treat SUI recur or persist after primary.

Objective To explore the clinical value of thermal tomography (TT) in the diagnosis of breast diseases.Methods Totally 222 breast diseases patients underwent examinations by color Doppler ultrasound and TT.Some stable TT images were selected,and the TT curves of the lesions were analyzed according to the malignant tumor TT curve diagnosing standard,so that the benign and malignant tumors could be determined.Color Doppler ultrasound was used to describe the site,size and property of the lesion.Results Pathological examination found 95 cases of malignant tumors and 127 benign ones.TT had 198 results coincident with those by pathological examination while the remained 24 ones not,with 15 false positive results and 9 false negative ones.When compared with pathological examination,TT had the accuracy,sensitivity and specificity being 89.19％,90.43％ and 88.28％ respectively.Conclusion TT is non-invasive,accurate and sensitive when used to screen and diagnose breast diseases,and should be applied if possible in medical facilities.
