BACKGROUND: Attention deficit and hyperkinetic disorder (ADHD) isfrequently treated with psychostimulant medications, which had beenshown to improve both cognitive and behavioral outcomes for most chil dren. OBJECTIVE: To compare the efficacy and adverse effects of olanzapinevs methylphenidate treatment in childhood hyperkinetic syndrome.DESIGN: Clinical comparative study. SETTING: Department of Psychiatry, Beijing Huilongguan Hospital; De partment of Mental Psychiatry, Shangdong Mouping People's Hospital. PARTICIPANT S: Sixty children with hyperkinetic syndrome from theclinics of the Department of Psychiatry,Beijing Huilongguan Hospital andthe Department of Mental Psychiatry of Shandong Mouping People's Hos pital between March 2002 and April 2004 were enrolled into this prospec tive study after obtaining the consents from their guardians.The patientswere randomly divided into 2 group: the olanzapine group (n=30) and themethylphenidate group (n=30). METHODS: In the olanzapine group olanzapine 2.5-7.5 mg per day wasgiven as a single dose in every evening.In the methylphenidate groupmethylphenidate 5-15 mg per day was given in divided dose in everymorning and evening.The dosage ofolanzapine and methylphenidatewere adjusted according to age, body mass and patient's clinical condi tions. And the period of treatment for either drug was 12 weeks. Conners teachers scale was used before and at the end of the 12 weektreatment(①hyperkinetic index consisted of 10 items②hyperkinetic behavior factorconsisted of 7 items. Each item was rated “none=0, a little=1, quite alot=2, and very much=3 ). Side effect scale was used to evaluate the hy perkinetic symptom and adverse reactions which consisted of behavior toxicity, abnormal laboratory tests , symptoms of the nervous system, au tonomic nervous system, cardiovascular system and skin etc with. 0=none; 1 =suspicious or very mild, 2=mild, 3 =moderate, 4=severe. The highestscore was 22,and the lowest was 0 with a score over 2 being positivefinding). MAIN OUTCOME MEASURES:Hyperkinetic syndrom score and ad verse reaction score at the end of the 12 weeks treatment. RESULTS:All 60 children completed the study and their results wereentered into the data analysis① At the end of the 12th week treat ment, the total hyperkinetic index score and total behavior score in boththe olanzapine group and the methylphenidategroup were significantly lower than those before the treatment as shown in Table 1 (t=8.16-15.26, P ＜ 0.05-0.01 )]; The total hyperkinetic behavior score in the olanzap inegroup was significantly lower than that in the methylphenidategroup (t=2.69, P ＜ 0.05 ). ② The adverse reaction score of patients inthe olanzapine group and the methylphenidategroup was 10.3±4.5and 10.9±3.8 respectively ,with no significant difference(P ＞ 0.05)between the two groups. CONCLUSION: Olanzapine produced similar effect as methylphenidatein the treatment of the hyperkinetic symptoms and attention deficits with a better efficacy in treating the behavior disorder than methylphenidate.

Objective To assess the effectiveness of extra-anatomic prosthesis bypass in the retroperitoneum as a treatment for infected abdominal aortic aneurysms (iAAAs).Methods We retrospectively reviewed the records of 10 consecutive patients diagnosed with iAAAs and treated by an extraanatomic prosthesis bypass in the retroperitoneum over the past 7 years.All 10 patients were regularly followed up by outpatient observation after their discharge.Results Ten patients with iAAAs underwent an extra-anatomic prosthesis bypass in the retroperitoneum and debridement of the infected aneurysm.An emergency operation was performed for one patient who underwent concomitant gastrointestinal procedures for aortoduodenal fistula,the other 9 cases underwent an elective operation after an intravenous antibiotic therapy for 2-4 weeks.All 10 patients were definitely diagnosed by one or more sequential CT scans combining with other methods.All patients had at least a positive preoperative blood culture or intraoperative tissue culture during the perioperative period,including Salmonella in 5 cases,Burkholderia pseudomallei in 3 cases,Escherichia coli in 1 case,Klebsiella pneumoniae in 1 case.All patients were discharged in 4-6 weeks after their operations.Except 1 case who died 16 months after surgery,all other patients were alive and were free from graft infection during the follow-up period.Conclusions The extra-anatomic prosthesis bypass in the retroperitoneum for treating iAAAs are safe and effective.

Objective To explore the miRNA regulating the potential cancer-promoting gene CCL18 in cutaneous malignant melanoma.Methods Bioinformatics analysis was conducted by using online software miRanda and TargetScan,so as to predict the miRNA targeting CCL18 gene.Three kinds of C CL18 3'UTR dual-luciferase reporter vectors,including mutant 3'UTR vector (mutant 3'UTR group),wildtype 3'UTR vector (wild-type 3'UTR group) and empty vector (blank control group),as well as miRNA vectors carring selected miRNAs were constructed according to human gene sequence analysis,and then were used to co-transfect 293T cells.After 48-hour treatment,the cells were lysed for detection of luciferase activity.Real-time fluorescence-based quantitative PCR was performed to measure the expression of CCL 18 and selected miRNA in 14 fresh malignant melanoma tissue specimens and 14 paracancerous normal skin tissue specimens (control tissues),and their correlations were analyzed.Results Online software analysis showed that some miRNAs were identified to target the 3'UTR of CCL18 gene,including miR-183,miR-128 and miR-33a.Luciferase reporter vectors and miRNA vectors were constructed successfully.As luciferase activity assay showed,when miR-183 and miR-128 were bound to the CCL18 3'UTR,the luciferase activities were significantly higher in their mutant 3'UTR groups (11.63 ± 0.42;8.80 ± 0.49) than in their wild-type 3'UTR groups (4.86 ± 0.39;5.01 ± 0.54;both P ＜ 0.05) and blank control groups (2.41 ± 0.13;2.39 ± 0.05;both P ＜ 0.01),while there were no significant differences between miR-33a-hinding mutant 3'UTR group (6.41 ± 0.47) and miR-33a-binding wild-type 3'UTR group (6.16 ± 0.22,P ＞ 0.05).Real-time fluorescence-based quantitative PCR revealed higher mRNA expression of the CCL18 gene (3.52 ± 1.68),but lower expression of miR-183 (0.49 ± 0.32),miR-128 (0.30 ± 0.20) and miR-33a (0.46 ± 0.40) in the malignant melanoma tissues compared with the control tissues.The mRNA expression of the CCL18 gene was negatively correlated with the expression of miR-128 (rs =-0548,P ＜ 0.05),but showed no significant correlations with the expression of miR-183 and miR-33a (both P ＞ 0.05).Conclusion miR-128 may play a role in regulating the potential malignant melanoma-promoting gene CCL18.

Objective To study the mechanism of glutamine dipeptide on wound healing after operations on bums. Methods Totally, 30 burned patients were randomly divided into study group and control group (15 cases in each group). All patients received parental nutrition support after operation. Study group patients were supplemented with glutamine dipeptide at a dose of 0. 5 g · kg±1 · d±1. The plasma free hydroxyproline level was measured by a standard amino acid analyzer 1 day before operation and 7 days after operation and the wound healing time was recor± ded. Results The plasma free hydroxyproline levels of both groups were higher than the normal values before opera± tion but without significant difference [control group: (2. 24 ±0. 84) fig/ml, study group: (2. 32 ±0.92) μg/ml, normal value: (1.27 ±0.44) μg/ml]. On the post±operative 7 day, the plasma free hydroxyproline level of study group [ (4. 31 ±1. 05) μg/ml] was significantly higher than that of control group [ (3. 04± 1. 01) μ/ml] (P = 0.002). The wound healing time of study group [ (29. 7±5.3) d] was shorter than that of control group but with± out significant difference [ (33. 3 ±7.5) d, P = 0. 14 ]. Conclusion The intravenous supplementation of glutamine dipeptide may increase the plasma hydroxyproline level after operation and thus promote wound healing.

Objective To evaluate the efficacy and safety of triethanolamine cream in the treatment of skin ulcer. MethodsA multicenter,single-blind,randomized,positive-control study was conducted.One-hundred and twenty patients aging 18-65 years with skin ulcer were randomly classified into the test and control group at a ratio of 2 ∶ 1 to be treated with triethanolamine cream and recombinant bovine basic fibroblast growth factor gel respectively for 4 weeks.The healing rate of ulcer,granulation tissue production rate and epithelialization rate were calculated.Results After the beginning of treatment,the condition of all patients was improved with time.In total,76 out of 80 triethanolamine-treated patients and 38 out of 40 basic fibroblast growth factor gel-treated patients completed the 4-week trial.Significant differences were observed in the healing rate of ulcer,epithelialization rate and granulation tissue production rate between the test and control group (71.05％ vs.34.21％,P =0.0002; 85％ vs.50％,P =0.0001; 66.25％ vs.37.5％,P =0.0035).No adverse events occurred in any of the patients.Conclusions Triethanolamine cream seems superior to recombinant bovine basic fibroblast growth factor gel with regard to the healing rate of ulcer,epithelialization rate and granulation tissue production rate,and may be a promising drug for the treatment of skin ulcer.

Objective Compare the efficacy of superselective arterial embolization with observation in the treatment of HFP caused by trauma.Methods From Jan,2013 to Dec,2017,6 traumatic HFP patients were involved into the study,the age range from 18 to 44 years old,with an average age of 26.2 years.The fistula was measured by doppler ultrasonography before the treatment with its longest diameter,and which ranges from 0.8 to 1.4 cm,the average diameter is 1.14 cm.All patients are divided into two groups according to their treatment.Operation group:4 patients underwent the pudendal artery superselective gelatin sponge vascular embolization.Control group:2 cases were treated with local cold compressing under watchful waiting.In control group,patients are treated by local cold compress with ice bag for 3 weeks:15 mins × 10 times every day.The erectile hardness of the patients was observed and the fistula was evaluated by doppler ultrasonography 3 weeks later,and all the patients were reexamined by doppler ultrasonography 1 year later.The erectile hardness was divided into four grades according to the patient~ subjective feelings:grade Ⅰ,the penis was enlarged but not rigid;grade Ⅱ,the penis had hardness,but not enough to insert into the vagina;grade Ⅲ,the penis could be inserted into the vagina,but not to achieve complete erection;grade Ⅳ,the penis fully erect and firm.The erectile function was evaluated with the International Index of Erectile Function-5(IIEF-5) after 1-year's follow-up.Results 4 patients in the operation group were operated successfully without obvious complications after operation.Median follow-up time of all the patients was 21 months (5-50).In group operation,4 cases of surgical patients did not have the recurrence of priapism.There was no obvious abnormality in the color doppler ultrasound of penis.The score of IIEF-5 was 25,24,24 and 23,respectively.Postoperative erectile function made a complete recovery.In group observation,2 patients under watchful waiting still have grade Ⅱ-Ⅲ sustained priapism,IIEF-5 score is 21 and 19 respectively,the penis color doppler ultrasound scan still showed the change of arteriovenous fistula.Conclusion Superselective arterial embolization is effective in the treatment of HFP,and the recovery of sexual function is better after operation compared with watchful waiting.

Purpose: The causal relationship between the incidence and prognosis of chronic kidney disease (CKD) and serum testosterone levels in patients is not yet fully understood. This study aims to use the National Health and Nutrition Examination Survey (NHANES), a large-scale nationally representative sample, to investigate the relationship between CKD and testosterone. Materials and Methods: This study included six NHANES cycles for linear regression analysis, verified by multiple imputation methods. Stratified analysis and subgroup analysis were used to demonstrate the stability of CKD’s effect on testosterone. Furthermore, we used Kaplan-Meier plots and log-rank tests to evaluate differences in survival rates between CKD male patients with low and normal levels of testosterone. Results: From a total of 71,163 subjects, the cohort selected 28,663 eligible participants. Results showed that CKD patients had testosterone levels 28.423 ng/mL (24.762, 32.083) lower than non-CKD patients. The results of multiple imputations (β=27.700, 95% confidence interval: 23.427, 31.974) were consistent with those of linear regression analysis, and the numerical match was good. Stratified regression analysis, and subgroup analysis results showed that CKD had a significant impact on testosterone at different dimensions. Kaplan-Meier plots showed significantly reduced survival rates in low testosterone CKD male patients (p<0.0001). Conclusions The results of this big data analysis suggest that there may be a two-way risk between low levels of testosterone and CKD. The testosterone levels of CKD patients were significantly lower than those of the non-CKD population, and CKD patients with low testosterone levels had poorer prognoses. These results suggest that correcting testosterone levels in a timely manner can have preventive and therapeutic effects on the progression of CKD.

OBJECTIVETo prepare and characterize rabbit polyclonal antibodies against Toxoplasma gondii vacuolar proton pyrophosphatase type I (TgVP1).

METHODS AND RESULTSTwo synthesized peptides TgVP1-1 and TgVP1-2 as the haptens were conjugated with KLH to immunize rabbits. Indirect ELISA showed that the titers of rabbit anti-TgVP1-1 polyclonal antibody and rabbit anti-TgVP1-2 polyclonal antibody reached 1:128 000. Western blotting results revealed that both purified polyclonal antibodies could specifically bind to a purified 85 kD T. gondii protein predicted as TgVP1. The protein detected by these two polyclonal antibodies was distributed in the cytoplasm of T. gondii tachyzoite, and this distribution pattern was consistent with that of acidocalcisome.

CONCLUSIONThe peptide-based method of antibody generation is efficient and the obtained TgVP1 polyclonal antibodies possess a high specificity to facilitate further study of T. gondii acidocalcisome and the diagnosis of toxoplasmosis.
