Progress of Shwachman-Diamond syndrome / 中华实用儿科临床杂志

Shwachman - Diamond syndrome (SDS)is a rare autosomal recessive disorder,SDS is characte-rized by exocrine pancreatic dysfunction,bone marrow failure,skeletal abnormalities and various other organ dysfunc-tions,and predisposition to MDS and acute myelogenous ceukemia. The Shwachman - Bodian - Diamond syndrome (SBDS)gene located on chromosome 7q11,the common mutation type is 183_184 TA > CT and 258 + 2 T > C. The purpose of this document is to comprehensive analysis the relevant literatures,analyze its clinical characteristics,geno-type,diagnosis and treatment suggestions to improve the clinician knowledge of the disease.

The relationship among depression, anxiety, stress and addictive substance use behavior in 5 935 secondary vocational students / 中华预防医学杂志

Objective@#To investigate the relationship among depression, anxiety, stress and addictive substance use behavior in secondary vocational students.@*Methods@#Cluster sampling method and the Adolescent Health-related Behaviors Questionnaire were used to collect demographic characteristics, psychological symptoms, and addictive substance usage among 5 935 students in nine vocational schools in Chongqing, Zhaoqing, Ningbo, and Taiyuan. Multivariate logistic regression analysis was used to analyze the relationship between the addictive substance use behavior and psychological factors.@*Results@#The detection rates of depression, anxiety and stress were 46.5% (n=2 762), 58.7% (n=3 483), and 29.8% (n= 1 770), respectively. The prevalence of addictive substances was 74.8% (n=4 440), traditional drugs was 0.8% (n=50), new drugs was 2.8% (n=166), other addictive drugs was 4.1% (n=241). Multivariate logistic regression analysis showed that compared with the normal psychological states of secondary vocational students, the OR value of mild depression tendency alcohol and tobacco use behavior of secondary vocational students was 1.45; the OR values of mild anxiety, moderate anxiety, severe anxiety and very serious anxiety were 1.46, 1.46, 1.71, and 1.83, respectively; the traditional drugs use behaviors were 5.51, and 2.61, respectively, for the severe anxiety and very serious anxiety. Compared with the normal psychological state of secondary vocational students, the OR values of the severe anxiety and very severe anxiety were 2.56, and 2.66, respectively, for severe anxiety and very serious anxiety. Compared with normal psychological status of secondary vocational students, the OR values of mild, moderate, severe, and very severe anxiety were 2.14, 2.47, 2.39, and 3.45, respectively; all P values <0.05.@*Conclusion@#Anxiety and mild depression were risk factors of tobacco and alcohol use in secondary vocational students; severe and above anxiety were the risk factors of drug use in secondary vocational students; anxiety was the risk factor for other addictive drug use in secondary vocational students.

The negative effects of Trim34α on activation of luciferase reporter gene containing NF-κB promoter / 中华微生物学和免疫学杂志

Objective To investigate the effects of Trim34α on the activation of luciferase reporter gene containing NF-κB promoter induced by adaptor proteins TAB2. Methods The total RNA was isolated from HeLa cells. After amplification with RT-PCR, the target sequences were cloned into 5'-Flag-pcDNA3.1 (+) vector. The recombinant vector was confirmed by restriction enzyme digestion, colony PCR and sequencing. It was transfected into HEK293T cells to detected Trim34α expression by Western blot. Simultaneously, the effects of Trim34α on the NF-κB activation induced by TAB2 were determined by dual-luciferase reporter assay. Results Restriction enzyme digestion, colony PCR and sequencing confirmed the vector was constructed successfully, furthermore it expressed Trim34α protein in HEK293T cells. Moreover, trim34α could form high-molecular-weight oligomeric protein, and here we called it trimsome. Interestingly, dual-luciferase assay showed that Trim34α could effectively block TAB2-induced NF-κB activation. Conclusion Trim34α was involved in negative regulation of TAB2-induced NF-κB activation and could form high-molecular-weight oligomer.

One phase treatment of renal calculi accompanied with pyonephrosis by percutaneous nephrolithotripsy / 中华泌尿外科杂志

Objective To evaluate the method, clinical efficacy and safety of one phase treat-ment of renal calculi associated with pyonephrosis by percutaneous nephrolithotripsy(PCNL) by pneu-matic combined with ultrasonic lithotriptor. Methods Sixty-six cases of renal calculi accompanied with pyonephrosis were treated with PCNL. The renal calyx was punctured under ultrasound gui-dance, then the tract was dilated from F8 to F16 by peel-away vascular access sheathes. After the in-sertion of the flexible sheath, metallic dilator was inserted and the flexible sheath was pulled out. The tract was dilated by metallic sheath to F21 and the operation sheath and nephroseope were placed into working tract. EMS III LithoClast Master was used. Ultrasonic powered lithotriptor probe with suc-tion was used to clear the liquor puris and calculus fragments with low-pressure or no-pressure. The combined pneumatic and ultrasonic powered lithotriptor was used to break and clear the calculi. Re-salts Of the 66 cases, there was no bacteremia or pyaemia intraoperatively and postoperatively. And there was no other severe complication occurred intraoperatively. One phase PCNL was successfully completed in 60 cases. Other 4 cases had residual calculi less than 1.5 em in diameter and received ESWL to break the calculi, 2 cases had bigger residual calculi and accepted second PCNL 1 week after the first intervention. In the follow-up period, the 3 month post-operative serum Cr was 56-203 μmol/L with an average decrease of 40 μmol/L, GFR was 5.0-56.2 ml/min with an average increase of 23.6 ml/min compared with the pre-operative data. At 6 months postoperative serum Cr was 56-158 μmol/L with average decrease of 31 μmol/L, GFR was 5.0-79.2 ml/min with an average in-crease of 30.2 ml/min. Conclusion Application of PCNL in the treatment of patients with renal cal-culi accompanied with pyonephrosis is safe, cost-effective and clinically efficient by pneumatic com-bined with ultrasonic lithotriptor.
