objective To evaluate the clinical application value of ileum to the S-type of suture pro- duced orthotopic neobladder.Methods Radical cystectomy and ileal neobladder with"S"shape were per- formed in 3patients with transitional cell carcinoma.Ureter implant into neobladder with embedding nipple techniques,bottom of neobladder coincide with urethra stump.Results The average operative time to form a neobladder was 5 hours,average bleeding volume was 366 ml during operation,3 cases can control urine dur- ing daytime,nycturia 1-3 times every night.Neobladder has a large capacity,low pressure,and electrolytes of blood was normal.Conclusion The construction of an ileal neobladder using a smaller part of ileum that has been completely detubularized and fashioned by S shape is easy and agreeable to perform.This mode of oper- ation has low complication rates,achieves adequate capacity at low pressure,and provides satisfactory conti- nence rates.It is a fine scheme to treat invasion and multiple carcinoma of bladder.

Objective To analyze the present situation of iodine deficiency disorders (IDD) in Henan Province,and to promote implementation of sustainable control strategies.Methods In 2011,a stratified proportion to population probability sampling (PPS) method was used to survey 1200 children aged 8 to 10 in 30 counties of the province.One primary school was selected in each chosen county.Goiter,intelligence quotient (IQ),urinary iodine and salt iodine level were studied.Meanwhile,12 families per capita salt intake was investigated.In each school,30 5th-grade students and 30 pregnant and lactating women in the school townships and adjacent neighboring townships were selected to carry out questionnaire survey on health education with unified papers.Results ①The goiter rate of children aged 8 to 10 by B ultrasound was 4.5％ (54/1201) ; the IQ of 1080 children was 107.75 ± 16.81 ; median urinary iodine level of 358 children was 201.4 μg/L.②The median of salt iodine content was 28.6 mg/kg,the coverage rate of iodized salt was 98.8％ (1186/1200),and qualified rate of iodized salt was 93.0％ (1116/1200).③The residents average daily salt intake was 10.5 g.④Average score of the questionnaire survey of 1084 5th-grade students was 4.2 points.Average score of 961 housewives was 4.4 points.Conclusions Various technical indicators show that IDD is in a sustained elimination state in Henan Province.Strengthen health education,enhance public awareness of disease prevention is still the important work ahead.

Objective To analyze the examination results of external quality assessment(EQA) at all levels of iodine deficiency disorders(IDD) laboratories in Henan province and the network operation to further standardize and improve the laboratory,and to provide reliable laboratory quality assurance for surveillance and control of IDD.Methods The examination results of EQA at all levels of IDD laboratories in Henan province were statistically analyzed in accordance with the National Reference Laboratory (NRL) of IDD (1999-201 1).Results The survey results showed that the provincial level laboratory was all qualified in testing urinary iodine and salt iodine in the past 13 years.In prefectural level,the laboratory response rates were 100.0％,and through participation in EQA,laboratory capacity had been significantly increased and stabilized.From 1999 to 2001,the passing rate of check up of urinary iodine was 22.2％ (4/18),72.2％ (13/18),94.4％ (17/18),respectively,and the rate was stable at 100.0％(18/18) from 2002 to 2011 except 94.4％ (17/18) in 2003.Since 2000,the prefectural level laboratory began to take part in the salt iodine EQA,and the laboratory response rate was 100.0％ (18/18) from 2000 to 2011.Except 88.9％(16/18) in 2003,the passing rate of check up of urinary iodine was 100.0％(18/18)from 2000 to 2011.In 2003 and 2004,6 to 7 county-level laboratories participated in the EQA of urinary iodine in Zhengzhou city,respectively,and all qualified.The number of county-level laboratories that participated in the salt iodine quality control network increased from 29 in 1999 to 148 in 2011.Response rate was 94.4％(68/72),96.7％(58/60) and 92.3％(144/156)in 2003,2006 and 2007,respectively,and the rate remained stable at 100.0％ in the remaining 10 years.In 1999,the passing rate was 69.0％ (20/29),then increased significantly,except 86.7％ (26/30) in 2001 and 84.6％(132/156) in 2007,the rates were all above 90.0％ in other years,especially in 2000 and 2009,the passing rates were both 100.0％.Conclusions The accuracy of test results of external quality controls and the normal operation of the network at all levels of laboratories is closely related to the IDD laboratory conditions and detection techniques.

OBJECTIVETo prepare monoclonal antibodies of mice anti-human sperm protein 22 (SP22) and to identify their specificities.

METHODSBALB/c mice were immunized with human SP22, monoclonal antibodies were prepared by hybridoma technique and the sensitivity and specificity of SP22 McAb were investigated by ELISA and Western-blot assay, respectively. The distribution of human SP22 in sperm were shown by immunohistochemistry.

RESULTSThree strains of hybridoma cells were obtained, with the affinity constant (K) of 1.0 x 10(7) L/mol and the titers were 1:10(3) and 1:3,200 in the mixed supernatant of cell cultures and abdominal dropsy, respectively. IgG isotype of the antibody was identified as IgG1. Western blot demonstrated that there was a specific recognition between human SP22 and the obtained monoclonal antibody. Immunohistochemistry displayed that human SP22 mainly distributed on the acrosome surface of human sperm.

CONCLUSIONThe monoclonal antibodies of anti-human 22 was prepared by the technique of hybridoma cell has higher titer and specificity, which can combine specially with the SP22 protein on the surface of human sperm.

OBJECTIVETo investigate the regulation trend of Jinxin Oral Liquid (JXOL) on the expression of negative regulatory factor of TLR3 signaling pathway SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points.

METHODSTotally 75 BALB/c mice were randomly divided into 5 groups, i.e., the normal control group, the model group, the ribavirin group, the high dose JXOL group, and the equivalent dose JXOL group, 15 in each group. Each group had 3 intervention ways (I, II, and III) with 5 mice treated in each group. BALB/c mice were nasally infected with respiratory syncytial virus (RSV), and treated by different intervention ways. After intervention, mice were killed and their lung tissues were sampled, mRNA expression levels of RSV-M, SOCS1, and IFN-β were detected by Real time PCR. The expression of SOCSl at the protein level was detected by Western blot.

RESULTSCompared with the normal control group, the mRNA expression level of SOCS1 and IFN-β, and the protein expression level of SOCS1 increased significantly in the model group intervened by intervention I and II (all P < 0.01), but the mRNA expression level of IFN-β decreased significantly in model group intervened by intervention III (P < 0.01). Compared with the model group, the mRNA expression level of RSV-M all significantly decreased in the high dose JXOL group and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and III and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of IFN-β significantly decreased in the high dose JXOL group intervened by intervention I and II and the equivalent dose JXOL group intervened by intervention I (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III and the equivalent dose JXOL group intervened by intervention III (all P < 0.01). The protein expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III (all P < 0.01). Compared with the high dose JXOL group, the mRNA expression level of RSV-M decreased significantly in the equivalent dose JXOL group intervened by intervention I and II (P < 0.01). The mRNA expression level of SOCS1 and IFN-β decreased significantly in the equivalent dose JXOL group intervened by intervention I (P < 0.01), but the mRNA expression level of IFN-β increased significantly in the equivalent dose JXOL group intervened by intervention II and III (all P < 0.01). The protein expression level of SOCS1 decreased significantly in the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01).

CONCLUSIONSJXOL could inhibit the expression of SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points. Its regulatory effect might be associated with promoting the expression of interferon type I and further fighting against RSV.

OBJECTIVETo determine the expression of Skp2 in different prostate cancer (PCa) cell lines and tissues, and explore its influence on the androgen receptor (AR) signaling pathway and development of castration-resistant prostate cancer (CRPC).

METHODSThe expression levels of Skp2 and AR in different PCa cell lines were detected by Western blot. After knockdown of Skp2 in the C4-2 and 22RV1 cells transfected with shRNA, the expressions of AR and P27 were determined and the activity of ARR3-Luc measured by dual-luciferase reporter gene assay following treatment with dihydrotestosterone (DHT). The expressions of AR and Skp2 in human naïve PCa or CRPC specimens were detected by immunohistochemical staining followed by analysis of their differences and correlation.

RESULTSThe Skp2 protein expression level was significantly higher in the C4-2 or 22RV1 cells than in the LNCaP cells. DHT treatment increased the expression of Skp2 in the C4-2 cells, but knock-down of Skp2 significantly up-regulated the expression of the well-known downstream protein P27 and down-regulated that of AR. Consistently, DHT treatment increased the activity of ARR3-Luc, while knockdown of Skp2 remarkably decreased it in the C4-2 and 22RV1 cells (P < 0.05). In addition, significantly higher expressions of Skp2 and AR were observed in the CRPC than in the naïve specimens (P < 0.05), with a positive correlation between the two proteins (r = 0.658 1, P < 0.05).

CONCLUSIONSkp2 can enhance the expression and transcription activity of the AR protein in CRPC cells or tissues and is promising to be a critical molecular therapeutic target.

OBJECTIVETo investigate the principle of management of colorectal high-grade intraepithelial neoplasia(HGIN) based on colonoscopic biopsy.

METHODSPatients diagnosed as colorectal HGIN based on colonoscopic biopsy in the Changhai Hospital from January 2002 to December 2009 were enrolled in the study. The clinical data of all the patients were collected and analyzed. According to the subsequent operation, cases were divided into local complete resection group and radical operation group. The discrepancy between the biopsy diagnosis and postoperative diagnosis was investigated.

RESULTSOf the 203 biopsy-based colorectal HGIN lesions, 156 underwent radical resection, while 47 received local complete resection. Univariate analyses indicated that tumors located in colon(P=0.02), tumors with sessile growth (P=0.00) and large tumors (P=0.00) were more likely to be treated with radical resection. Postoperative diagnosis revealed that 163 cases(80.3%) were invasive cancers, while the other 40 cases(19.7%) were HGIN lesions. Of the 156 cases resected radically, 140 cases were invasive cancers, 16 cases were diagnosed as HGIN. Of the 47 cases who underwent local complete resection, 24 cases were confirmed as HGIN but the other 23 cases were invasive cancers, in which 15 cases received subsequent radical operation.

CONCLUSIONSA large proportion of biopsy-proven colorectal HGIN lesions are invasive cancers. Therefore, local resection should be performed to confirm diagnosis. For highly suspected malignant tumors which can not be removed completely by local resection, if anus can be reserved, a radical transabdominal surgery is recommended even without biopsy-proven malignancy in order to avoid treatment delay.
