Objective:To analyze the incidence trend, current status and survival period of young patients with lung cancer aged from 15 to 44 years in Shanghai between 2002 to 2005. Methods:All the data were collected from the database of registration and ma-nagement system of diagnosed cancer cases in Shanghai city organized by Shanghai Municipal Center for Disease Control & Prevention. The incidence trend was analyzed by using APC(annual percent change)model. The survival period and median survival time were calculated by using SPSS 12.0 software and life table method. The univariate and multivariate analyses were analyzed by using Kaplan-Meier and COX regression model, respectively.Results:A total of 972 young patients with lung cancer who aged from 15 to 44 years were diagnosed in Shanghai between 2002 and 2005, accounting for 3.09% of the whole percentage of adenocarcinoma in young patients was higher than that in whole lung cancer population at the same period, while the TNM stage was not significantly different between male and female young patients. Multivariate analysis demonstrated that gender, pathological classification and TNM stage were independent prognostic factors for young patients with lung cancer. Conclusion:The lung cancer had different characteristics in young patients compared with that in whole lung cancer population in Shanghai city. It was necessary to further investigate the biologic behavior of lung cancer in young patients.

Objective To investigate the protective effects of Wnt-7a protein on renal interstitial fibrosis in mice of unilateral ureteral obstruction (UUO)model.Methods Eighteen male C57BL/6 mice were randomly divided into 3 groups:sham-operation group,the UUO model group and Wnt-7a treatment group.The body weight of mice was measured everyday.All the mice were sacrificed at thc seventh day after the operation.The left kidney was taken for histology evaluation and molecular biology assay.Masson's stain was performed as a main indicator of interstitial fibrosis.The expression of vimentin,α-smooth muscle actin,and E-adherin in renal tissue was detected by immunohistochemistry staining and the expression of α-smooth muscle actin and E-cadhe(nn) in renal tissue was detected by Western blotting.Results Compared with sham-operation group,body weight of the (,)odel group was significantly lower (P＜0.05),and the relative area of interstitial fibrosis was significantly larger (P＜0.05).Furthermore,the expression of vimentin and α-SMA was significantly up-regulated (P＜0.05),and the expression of E-cadherin was significantly down-regulated (P＜0.05).Compared with model group,all the above-mentioned abnormalities were restored to some extent and showed significant differences (P＜0.05) in Wnt-7a treatment group.Conclusion Wnt-7a protein can decrease the interstitial fibrosis by inhibiting epithelial to mesenchymal transition in UUO mice.

Objective To investigate the error monitoring function damages on the patients with schizo?phrenia ( SCH) . Methods A total of 32 patients with schizophrenia were compared with matched 34 health con?trols ( HC) on the error monitoring tasks which were compiled by E?Prime. Results The comparison between SCH group ((713.22±174.52)ms,( 491.14±170.29) ms,( 1060.31±130.84) ms,(8.28±12.55)time,( 8.00± 7.53)time respectively) and HC group ((560.73±156.94) ms,(395.62±188.03) ms,(989.85±104.33) ms, (2.97±4.13) times,(3.12±6.50) times) on the reaction time of choice,assessment,incongruent condition,the numbers of uncertain and the numbers of dropout were significant ( t=-3.737, P=0.000;t=-2.159, P=0.035;t=-2.426, P=0.018;t=-2.282, P=0.022;t=-2.824, P=0.006) . The SCH group and HC group did not signifi?cantly difference in Full Correct((124.72±23.74)/(131.74±21.96)times),Full Error((15.69±17.64)/(13.35± 18.63)times),Part Correct((6.83±10.40)/(4.21±7.03)times),Part Error((2.91±10.91)/(0.62±1.10)times) and Accuracy((0.831±0.161)/(0.874±0.159))(P>0.05).There was no significantly correlation among the course of disease,HAMA,HAMD and the error monitoring. Conclusion These results demonstrate that the error monitoring function damages on the patient with SCH may be involved in the dysfunction of anterior cingulate cortex.

Objective To investigate the prevalence,missed diagnosis rate and causes of acute kidney injury (AKI) in hospitalized children,and its impact on hospitalization cost,length of stay and outcome.Methods The data of children admitted in Children's Hospital Affiliated to Capital Institute of Pediatrics from December 1st to 31st 2014 were collected,and those whose serum creatinine (Scr) were measured at least two times were selected.Patients were diagnosed as AKI according to the diagnostic criteria of 2012 Kidney Disease:Improving Global Outcomes,then divided into AKI group and non-AKI group,the former of which was further divided into AKI1 group (Scr peak value in normal range) and AKI2 group (Scr peak value above normal range).The causes and impact of AKI on hospitalization cost,length of stay and outcome in different groups were compared and analyzed.Results (1) Among 921 patients with at least two Scr results,170 patients met with the diagnostic criteria of AKI,including 100 males and 70 females.There were 112(65.9％) in AKI stage 1,43(25.3％) in stage 2,and 15(8.8％) in stage 3.The overall prevalence of AKI was 18.5％.With only 7cases getting diagnosed,the diagnostic rate was 4.1％,while 95.9％ of patients missed diagnosis.(2)Among AKI patients,67 cases had pre-renal causes,103 cases had intra-renal causes and mixed factors.100(58.8％) cases got complete recovery,34(20.0％) cases recovered partially and 36(21.2％)cases did not improve,including 4 cases of death.(3) The prevalence of AKI among those below 1-year old was higher than children elder than 1-year (23.0％ vs 15.5％,P=0.004).The prevalence of AKI in surgical ward was higher than medical ward (30.7％ vs 15.8％,P ＜ 0.001).(4) Compared with those in non-AKI group,there was lower age [1.1(0.2,3.5) year vs 2.0(0.3,4.9) year] and higher hospitalization time[12.5(8.0,20.0) d vs 8.0(6.0,11.0) d],hospitalization costs [25 279.2(13 822.8,48 856.7) yuan vs 12 616.9(8680.1,19 345.1) yuan] and mortality (2.4％ vs 0.3％) in AKI group (all P ＜ 0.05).(5) There were 126 cases in AKL group and 44 cases in AKI2 group.The costs of hospitalization,outcome and mortality showed no difference between two groups (all P ＞ 0.05).The hospitalization time in AKI2 group was shorter than that in AKL group (P=0.038).Conclusions Among hospitalized children the missed diagnosis rate of AKI is high.Pre-renal factor is the main cause of AKI.Children younger than 1-year old are more susceptible to AKI.AKI children have lower age and higher hospitalization time,hospitalization costs and mortality than non-AKI children.The effect of Scr fluctuation within normal levels needs to be further studied.

Objective To describe a novel surgical technique for male long-segment urethral stric- ture after pelvic trauma using the intact and pedieled pendulous urethra to replace the bulbar and membra- nous urethra,and then reconstructing anterior urethra.Methods Three patients with long-segment post- traumatic bulbar and membranous urethral strictures with short left pendulous urethras who had undergone several failed previous surgeries were treated with staged pendulous-prostatic anastomotic urethroplasty fol- lowed by reconstruction of the anterior urethra.This procedure was divided into 3 stages.The first-stage sur- gery was mobilization of anterior urethra down to the coronary sulcus and then re-routing the prostatic urethra followed by pendulous-prostatic anastomotic urethroplasty with transposition of penis to perineum.The sec- ond-stage surgery was transecting the anterior urethra at the site of coronary sulcus 6 months later when it was re-vaseularized,then straightening the penis and performing urethroperineostomy.The third-stage surgery was reconstruction of anterior urethra 6 months later.Results Case 1 reported satisfactory voiding postopera- tively.Retrograde urethrography showed that the urethra was patent with no post-voiding residual urine (PVR),and bilateral vesicoureteral reflux almost disappeared.The Qmax was 18.8ml/s,and 18ml/s after the third stage surgery and at 2-year follow-up.Case 2 also had satisfactory voiding.A 22F urethral catheter could smoothly pass through the urethra,and Qmax was 19.5 ml/s with no PVR at 2-year follow-up.Case 3 underwent the first stage surgery through perineal and pubic routes.The urethrorectal and urethroperineal fis- tulas were excised and repaired simultaneously.After operation the fistulas healed,but the stenostomia resul- ting from wound infection needed further treatment.Conclusions This procedure is effective for men with complex long-segment post-traumatic bulbar and membranous urethral strictures,especially for those undergo- ing failed previous surgical treatment.

Objective: To compare the efficacy of different treatment protocols in treating transient synovitis of the hip (TSH) in children and to optimize the clinical treatment strategy for this condition. Methods: Ninety kids with TSH were divided into a control group, a chiropractic group and a chiropractic plus foot bath group using the random number table method, with 30 cases in each group. The control group was treated with conventional traction; the chiropractic group was given chiropractic treatment based on the control group; the chiropractic plus foot bath group was given Chinese medicine foot bath based on the chiropractic group. Traction and foot bath were conducted once daily while chiropractic was done once every other day, all with 14 d as a treatment course for a total of two courses. Changes in the visual analog scale (VAS) score and range of motion (ROM) of the hip joint in the three groups were observed, and the efficacy was compared. Results: The total effective rate was 93.3％ in the chiropractic plus foot bath group, versus 76.7％ in the chiropractic group and 66.7％ in the control group, and the total effective rate was notably higher in the chiropractic plus foot bath group than in the other two groups (both P<0.05). Respectively after the first and second treatment course, the VAS score decreased significantly in each of the three groups compared with that before treatment (all P<0.01), and the ROM of the hip joint in flexion increased significantly (all P<0.01). After two treatment courses, the VAS score was lower in the chiropractic plus foot bath group than in the other two groups (both P<0.05), and its ROM of the hip joint in flexion was larger than that in the other two groups (both P<0.05). Conclusion: Based on traction, chiropractic plus Chinese medicine foot bath can effectively reduce pain and improve motor function of the hip joint in treating TSH.

Pathological cardiac hypertrophy is a maladaptive response in a variety of organic heart disease(OHD),which is characterized by mitochondrial dysfunction that results from disturbed energy metabolism. SIRT3, a mitochondria-localized sirtuin, regulates global mitochondrial lysine acetylation and preserves mitochondrial function. However, the mechanisms by which SIRT3 regulates cardiac hypertrophy remains to be further elucidated. In this study, we firstly demonstrated that expression of SIRT3 was decreased in AngiotensionⅡ(AngⅡ)-treated cardiomyocytes and in hearts of AngⅡ-induced cardiac hypertrophic mice. In addition, SIRT3 overexpression protected myocytes from hypertrophy, whereas SIRT3 silencing exacerbated Ang II-induced cardiomyocyte hypertrophy.In particular,SIRT3-KO mice exhibited significant cardiac hypertrophy. Mechanistically, we identified NMNAT3 (nicotinamide mononucleotide adenylyltransferase 3), the rate-limiting enzyme for mitochondrial NAD biosynthesis, as a new target and binding partner of SIRT3.Specifically,SIRT3 physically interacts with and deacety-lates NMNAT3,thereby enhancing the enzyme activity of NMNAT3 and contributing to SIRT3-mediated anti-hypertrophic effects.Moreover,NMNAT3 regulates the activity of SIRT3 via synthesis of mitochon-dria NAD.Taken together,these findings provide mechanistic insights into the negative regulatory role of SIRT3 in cardiac hypertrophy.Sirtuin 3(SIRT3),a mitochondrial deacetylase that may play an impor-tant role in regulating cardiac function and a potential target for CHF

Objective To develop a candidate reference method for the measurement of progesterone in human serum.Methods The serum sample is mixed with the internal standard [3,4-~(13)C_2] progesterone.After extraction with n-hexane and purified by a aqueous solution of 2-Hydroxypropyl-?- cyclodextrin (HP-?-CD),the serum progesterone and labeled progesterone are converted to the 3-enol heptafluorobutyrate and analyzed by gas chromatography mass spectrometry (GC/MS) with selected ion monitoring.The concentration of serum progesterone is calculated by bracketing method.Results The results gave coefficients of variation (CVs) of 0.69% to 2.12%.The analytical recoveries ranged from 98.3% to 100.1%.The results of measuring certified reference materials of serum progesterone are agree with the target value.Conclusion The procedure for measuring progesterone in serum is a highly accurate and precise method and may be used as a candidate reference method for serum progesterone assays.
