ObjectiveTo explore the correlations of simple bladder capacity measurement and urodynamic examination used for assessing the bladder function of patients with spinal cord injury.Methods From December 2011 to September 2013,a total of 37 patients with spinal cord injury were recruited.Their bladder functions were examined by both simple bladder capacity measurement and urodynamics in the first week after admission.The type of neurogenic bladder,residue urine,bladder capacity and the changes of bladder pressure were documented and compared.Results The simple bladder capacity measurement and urodynamics showed no significant differences in the parameters including residual urine,and bladder pressures when inputting 50mL,100mL,300mL and 400mL water(P>0.05). But there were significant differences in the results of bladder capacity and bladder pressure when inputting 200mL water(P<0.05). The intra-class coefficients between the results by the two methods were 0.606~0.919(P<0.01).The Kappa coefficient of the health professionals’judgments according to the two methods was 0.825(P<0.001).Conclusions The results of simple bladder capacity measurement are reliable.It can be used as the supplement for urodynamics to monitor the bladder function of patients with spinal cord injury.

OBJECTIVETo investigate the expression of cyclin A protein in childhood acute leukemia (AL) and its significance.

METHODSBy using Western blotting analysis, cyclin A protein in bone marrow mononuclear cells from 47 newly diagnosed AL children and 33 non-hematological malignancy children was detected.

RESULTSThe expression of cyclin A in AL group (0.38 +/- 0.20) was higher than that in control group (0.03 +/- 0.15) (P < 0.01). The expression of cyclin A in high risk acute lymphocyte leukemia (ALL) group (HR-ALL) (0.62 +/- 0.38) was higher than that in standard risk ALL group (SR-ALL) (0.33 +/- 0.33) (P < 0.05). The expression of cyclin A in WBC > or = 50 x 10(9)/L group and in WBC < 50 x 10(9)/L group was (0.64 +/- 0.36) and (0.39 +/- 0.38), respectively (P < 0.05). Eight (44.4%) out of 18 patients with positive cyclin A expression achieved complete remission (CR). The CR rate was lower than that of patients with negative cyclin A expression (100%) (P < 0.01).

CONCLUSIONSThe higher expression of cyclin A may predict a poor prognosis for childhood ALL.

OBJECTIVETo explore the impact of prenatal exposure to lipopolysaccharide on renin-angiotensin system of offspring rats.

METHODSSix pregnant SD rats were randomly divided into 2 groups. The rats in the lipopolysaccharide (LPS) group were treated with LPS 0.79 mg/kg (i.p.) on the 8th, 10th and 12th day of gestation, and rats in the control group were treated with saline at the same time points. The blood pressure of offspring rats was measured by the tail cuff method. Protein expression of Angiotensin II (AngII) in thoracic aorta vessel was determined by immunohistochemistry. Protein expressions of AngII type 1 and type 2 receptor in thoracic aorta vessel were detected by Western blot.

RESULTSBlood pressure of 12-week-old offspring rats of LPS group was significantly higher than that of 12-week-old offspring rats of control group (P < 0.01). The protein expression of AngII and AngII type 1 receptor in thoracic aorta vessel were significantly higher while protein expression of AngII type 2 receptor was lower in 15-week-old offspring rats of LPS group than in control group, resulting in a significant increase in the ratio of AngII type 1 receptor/AngII type 2 receptor in the aorta at 15-week-old of offspring rats than in 15-week-old offspring rats of control group (P < 0.01).

CONCLUSIONPrenatal lipopolysaccharide exposure results vascular renin-angiotensin system dysfunction, which may play an important role on the pathogenesis of hypertension development in offspring rats.

Objective To study the epidemiological characteristics of Keshan disease(KD) and its fiend so as to provide evidences for further research,prevention and treatment of the disease in Sichuan province.Methods Based on KD related data from 1990 to 2008,descriptive method was used to analyze the epidemiological characteristics of KD.Results 87 KD cases were identified during the 19 years.All cases were children from the countryside,with majority of them were Yi nationality.Age of the patients ranged from 5 months to 18 years,with majority at 2-6 year-olds.The annual incidence rates Were from 0/100 000 to 1.73/100 000 with 1999 the highest(1.73/100 000).A total number of 310 preclinical or chronic KD cases were identified and the total detection rates were between 0.28% and 2.8%.with 1992 the highest.As for levels of blood selenium during the 19 years:1995 appeared the lowest(0.1345 μg/g),followed by 1990-2000(0.1558 μg/g) but all of them fell in to the level in the KD epidemic areas.Conclusion There were 5 stages in the development trend of KD disease in Sichuan province,with 2 ascending and 3 descending.The differences between any of the two stages were statistically significant.The 3 descending stages all appeared right after the selenium supplement intervention was taken.Our data showed that the program of selenium supplement was closely related to the incidence of KD,suggesting that a long term mechanism of Selenium supplement in the epidemic areas should be taking into account.

Wulingsan， a classic prescription first recorded in the Treatise on Cold Damage （Shang Han Lun） by ZHANG Zhong-jing for patients with water retention syndrome due to the disturbance of Qi transformation in bladder， has often been modified by ancient and modern doctors for the treatment of renal diseases. It produced satisfactory outcomes without inducing adverse reactions. The databases including China National Knowledge Infrastructure （CNKI）， Wanfang Data Knowledge Service Platform， and PubMed were searched for articles concerning the clinical application and pharmacological mechanism of Wulingsan in the treatment of renal diseases published by domestic and foreign scholars in recent years. The summary of the included articles revealed that Wulingsan has been widely employed for the treatment of renal edema， diabetic nephropathy， acute and chronic glomerulonephritis， nephrotic syndrome， renal insufficiency， abnormal urination， etc.， and the resulting outcomes were satisfactory. Wulingsan alone or in combination with western medicine yielded better clinical outcomes than the western medicine alone. In the exploration of its pharmacological mechanism， there existed some individual reports by Korean scholars， while Chinese scholars tended to work as a team. After years of research， each team has found that Wulingsan was superior to Wulingsan decoction in excreting water， which might be related to the absence of massive low-polarity and volatile components in the decoction that were responsible for regulating the expression of aquaporins （AQP） in kidney of saline-loaded rats. Wulingsan regulates the endocrine state of rats with kidney yang deficiency， inhibits the reabsorption of water， increases the activity of Na⁺-K⁺-ATPase， and reduces the expression of AQP 1， AQP 2， AQP 3， and AQP 4. Besides， it bi-directionally regulates the human water metabolism， which is achieved via the dual-directional regulation of purinergic P2X3 receptor expression on bladder detrusor. The efficacy of Wulingsan in treating chronic renal failure is attributed to its protection against the damaged renal tissue，structure and fanction. Hence， this paper summarized the research progress of Wulingsan in the treatment of renal diseases in recent years， aiming to provide a reference for the clinical and basic exploration of Wulingsan against renal diseases in the future.

OBJECTIVETo explore the role of extrahepatic control on blood flow of hepatic vein and inferior vena cava in hepatectomy, and observe its effect on minimizing hemorrhage.

METHODSFrom 2001 to April 2003, 33 patients who had liver tumors involving segment IV, VII, VIII or half liver underwent major hepatectomies that required exposure of the inferior vena cava and main trunks of hepatic veins, during which the major hepatic veins and inferior vena cava were isolated and taped to control blood flow when necessary.

RESULTSIn 33 attempts, 32 were successful and all tumors were resected successfully. The placement of occlusion tape was unsuccessful in 1 case. 7 cases did not need blood transfusion during operation. The amount of blood transfusion for other cases were form 0 to 1 600 ml. there was no operative mortality.

CONCLUSIONSAppropriate control of main truck of hepatic vein and inferior vena cava is effective in reducing blood loss during hepatectomies. It is also very helpful for performing difficult hepatectomies.

【Objective】To prepare rapamycin（RAPA）sustained-release film and to evaluate its dissolution.【Methods】RAPA sustained- release film was created by using polymer polyactioglyconic acid （PLGA），copolymer of polyactic acid（PLA）and polyglycolic acid（PGA）. Drug content of the sustained-release film was determined using specificity test，recovery，relative standard deviation（RSD）and stability test. Then，the dissolution of the sustained- release film was analyzed.【Results】The concentration of RAPA had a linear relationship with peak area，which ranged between 0.408 μg/mL and 40.8 μg/mL through the standard curve. The specificity test of the drug content determination indicated the excipient of the film and the solution with 0.3% sodium dodecyl sulfate（SDS）did not affect in determining the RAPA content. The recovery and RSD were excellent through drug content determination in blank films，which had three different levels of RAPA concentrations. The mean RAPA content of the sustained-release films was（112.6±10.1）μg（RSD 8.99%）through the drug content determination of the films，and the stability of RAPA with 0.3% SDS was good within 15 days. In addition，dissolution test of the sustained- release film indicated that the amount of drug release reached a high level and sustained up to 15 days.【Conclusion】 The RAPA sustained-release film with certain behavioral characteristic parameters had a stable drug content and favorable sustained-release property，and it may have certain application potential in anti-proliferation after glaucoma filtering surgery.

BACKGROUNDAtopic dermatitis (AD) is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching. Most patients have personal and/or family history of atopic diseases. Several criteria have been proposed for the diagnosis of AD. Although the clinical features of childhood AD have been widely studied, there has been less large-scale study on adult/adolescent AD. The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczema/AD and to propose Chinese diagnostic criteria for adult/adolescent AD.

METHODSA hospital-based study was performed. Forty-two dermatological centers participated in this study. Adult and adolescent patients (12 years and over) with chronic symmetrical eczema or AD were included in this study. Questionnaires were completed by both patients and investigators. The valid questionnaires were analyzed using EpiData 3.1 and SPSS 17.0 software.

RESULTSA total of 2662 valid questionnaires were collected (1369 male and 1293 female). Of all 2662 patients, 2062 (77.5%) patients had the disease after 12 years old, while only 600 (22.5%) patients had the disease before 12 years old, suggesting late-onset eczema/AD is common. Two thousand one hundred and thirty-nine (80.4%) patients had the disease for more than 6 months. One thousand one hundred and forty-four (43.0%) patients had a personal and/or family history of atopic diseases. One thousand five hundred and forty-eight (58.2%) patients had an elevated total serum IgE and/or eosinophilia and/or positive allergen-specific IgE. Based on these clinical and laboratory features, we proposed Chinese criteria for adult/adolescent AD. Of all 2662 patients, 60.3% were satisfied with our criteria, while only 48.2% satisfied with Hanifin Rajka criteria and 32.7% satisfied with Williams criteria, suggesting a good sensitivity of our criteria in adult/adolescent AD patients.

CONCLUSIONLate-onset of eczema or AD is common. The clinical manifestations of AD are heterogeneous. We have proposed Chinese diagnostic criteria for adolescent and adult AD, which are simple and sensitive for diagnosis of adult/adolescent AD.

Aim To investigate the effect of marine herbal seahorse on chronic unpredictable mild stress ( CUMS ) -induced depression-like model in zebrafish. Methods Adult zebrafish were divided into control, Stress,Stress + low dose (Stress +0.044% SH) and Stress + high dose (Stress +0. 22% SH) seahorse intervention groups, and depression-like behavior was identified by novel tank test (NTT), cortisol, interleukin ( IL )-6 and interferon (IFN )-γ levels were detected by ELISA. The levels of dopamine (DA) ,norepinephrine (NE), 5-hydroxytryptamine (5-HT) and 5-hydroxyin-doleacetic acid (5-HIAA) were determined by high performance liquid chromatography. The mRNA expression levels of tryptophan hydroxylase(TPH)-2 and 5-HT2A receptor were measured by real-time quantitative PCR. Results Compared with the control group, the Stress group showed significantly longer latency to reach the top in NTT, significantly reduced number of transfers to the top region and top residence time, significantly increased levels of cortisol and IL-6, IFN-γ protein, significantly reduced levels of DA and 5-HT in brain as well as increased metabolism rate of 5-HT, while 5-HT2A mRNA expression was up-regulated and TPH2 mRNA expression was down-regulated. In contrast, low-dose seahorse intervention effectively reduced anxiety, decreased cortisol and IL-6 and IFN-γ concentrations, increased monoamine neurotransmitter levels and reversed dysregulation of the 5-HT ergic system in CUMS zebrafish. Conclusion Seahorse may exert an-tidepressant effects through anti-inflammation and mod¬ulation of monoamine neurotransmitter levels.
