Objective To investigate the effect of 12 Fr catheter on the catheteration for the patients with prostatic hypertrophy after stroke. Methods One hundred and four sixteen patients with prostatic hypertrophy from urinary detention were divided into the control group (n=80) and the observation group (n=84) based on the odd and even numbers of admission date according to a digit random table. The control group received catheteration with a 14~20 Fr catheter, and the observation group did with a 12 Fr catheter. The two groups were compared in terms of pains, urethral injury and leakage of urine during intubation. Result The pain, urethral injury, leakage of urine in the observation group were all significantly lowered than those of the control group (all P<0.05). Conclusions 12 Fr catheter for catheteration for the patients with post-stroke prostatic hypertrophy can significantly reduce the degree of pain, the urethral injury and leakage of urine. Thus it is worthy of clinical application.

Objective To assess the clinic application of a new-style automated immunoassay system HISCL ( high sensitivity chemiluminescent enzyme immunoassay ) with high sensitive chemiluminescence substrate CDP-Star?, bind-free separate technology and filter conversion technology.Methods The performance verification test evaluated HISCL′s specification including reproducibility, functional sensitivity, linearity, accuracy, and sensitivity for HBsAg seroconversion.To evaluate the specificity , 1 007 HBsAg-negative specimens , 82 potentially interfering specimens were from conventional specimens in West China Hospital , Sichuan University between October and December of 2014.At the same time, with these results to determine the rate of the specimens that their results are in negative grey zone.259 HBsAg-positive specimens and 27 weakly-positive specimens were tested for the comparison between the HISCL and ECLIA ( electrochemiluminescence immunoassay ) HBsAg quantification.A linear regression model , Pearson′s correlation and Bland-Altman analysis were used as statistical methods.Results The between day and within-lot variable coefficient of two level samples are 1.55%, 2.02%, 0.34%, 1.34%separately.The functional sensitivity of the HISCL HBsAg assay reaches 0.007 IU /ml.There is a good linearity (y=3.262x+0.082,r=0.994; y=2 303.608x-33.006,r=0.999) within range of 0-2 300 IU/ml.HISCL obtain the accurate results for the CAP control material , the agreement rate is 100%.The sensitivity for the detection of HBsAg seroconversion is high.The specificity is 99.91%.The negative grey zone rate is 1.66%.The results of these two methods have good correlation and uniformity , r=0.995, LOA:-0.3 -0.19 log10 IU/ml.Conclusions HISCL HBsAg detection system shows good detection performance.Be of the function of both qualitative and quantitative detection.And the negative “grey zone”specimen rate is low.It is wholly capable of wide linearity and quick assays for quantifying serum HBsAg levels.HISCL could contribute to improve HBsAg quantitative detection process for clinical laboratory.

Objective To investigate the role of mutations in C region that may contribute to occult hepatitis B virus infection.Methods C genes were amplified from two OBI blood donor samples respectively.Plasmids with mutations in C region of hepatitis B virus were constructed by overlapping PCR.HBsAg and HBeAg in Huh7 cells and in the serum of Balb/c mice were detected by CMLA.HBcAg in liver tissue was detected by immunohistochemistry,while HBV-RNA was tested by RT-PCR.Results Mutations in C region significantly reduced the expression level of HBeAg and HBcAg,but had no significant effect on HBsAg and HBV-RNA.Conclusion The mutations in C region affect the expression level of HBeAg and HBcAg,which may play an important role in the occurrence of OBI.

Objective:To explore the role of virtual reduction and design of 3D printed guide template in assisting reduction and internal fixation of comminuted patellar fractures.Methods:A retrospective study was conducted of 12 patients who had been treated for closed patellar fractures from March 2016 to April 2019 at Department of Orthopaedics, Jiangxi Provincial People's Hospital. They were 8 males and 4 females with an average age of 35.4 years (from 22 to 51). All their fractures were type 34-C3 (more than 3 fragments) according to the AO/OTA classification. Their preoperative CT data were imported into software Mimics to print a full patella, upper and lower halves of the patella, and a guide template for reduction. During operation, bone fragments were first temporarily fixated with a fine Kirschner wire after combined together with the assistance of reduction templates for upper and lower hemi-patellas. Next, the whole patella was precisely reset and definitely fixated using patellar ring ligation and tension band wire with the assistance of the reduction guide template for full patellar. Recorded were operation time, fluoroscopic frequency, and visual analogue scale (VAS), knee range of motion (ROM) and knee function B?stman scores at the last follow-up.Results:In this group of patients, operation time averaged 90 minutes (from 75 to 120 minutes), fluoroscopic frequency 4.5 times (from 3 to 8 times), follow-up duration 19 weeks (from 16 to 22 weeks), and fracture healing time 14 weeks (from 11 to 17 weeks). At their last follow-up, X-ray showed good patellar morphology, fine internal fixation positions and an average VAS pain scores of 0.3 (from 0 to 1), their knee joints could be fully straightened, their knee ROM averaged 130°(from 100° to 138°), and their knee B?stman scores 28.8 points (from 21 to 30 points), giving 9 excellent and 3 good cases.Conclusion:3D printed reduction guide templates can significantly improve the efficiency and quality of surgical reduction in comminuted patella fractures, enhancing fixation strength and facilitating early and full range exercise of the knee joint to achieve excellent recovery.

ABSTRACT OBJECTIVE：To study the improvement effect of Periplaneta americana extract Ento-A on damp-heat ulcerative colitis（UC）model rats. METHODS：Totally 70 rats were randomly divided into normal control group（n＝8）and modeling group （n＝62）. The damp-heat UC model was induced in modeling group by high sugar，high fat，spicy diet combined with 2，4， 6-trinitrobenzene sulfonic acid enema. 48 modelrats were randomly divided into model control group，mesalazine group （300 mg/kg），Changyanning group（300 mg/kg）and Ento-A low-dose，medium-dose and high-dose（50，100，200 mg/kg，calculated by the extract），with 8 rats in each group. Normal control group and model control group were given normal saline intrsgastrically，and other groups were given relevant medicine intragastrically，once a day，for consecutive 14 days. After last administration， disease activity index （DAI）， colonic mucosal injury index （CMDI） and histopathological score （HS）of rats were determined. The spleen index，liver index and colon index in rats were determined. The serum levels of IL-8，IL-17，SOD and MDA，colonic levels of IL-2，PGE2 and MPO were detected by ELISA. RESULTS：Compared with normal control group，the DAI score，CMDI score，HS score，colonic index，the serum levels of IL-8，IL-17 and MDA， colonic levels of MPO and PGE2 were increased significantly（P＜0.01）；serum level of SOD and colonic level of IL-2 were decreased significantly （P＜0.01）. Compared with model control group，DAI score，CMDI score，serum levels of IL-17 and MDA，colonic levels of PGE2 were decreased significantly in Ento-A high-dose groups（P＜0.05 or P＜0.01），while serum level of SOD and colonic level of IL-2 were increased significantly（P＜0.01）. CMDI score and HS score，serum levels of IL-8，IL-17 and MDA，colonic levels of PGE2 and MPO were decreased significantly in Ento-A medium-dose group（P＜0.05 or P＜0.01）， while colonic level of IL-2 was increased significantly（P＜0.01）. HS score，serum levels of IL-17 and MDA，colonic levels of MPO and PGE2 were decreased significantly in Ento-A low-dose group（P＜0.05 or P＜0.01），while serum level of IL-2 was increased significantly（P＜0.01）. CONCLUSIONS：P. americana extract Ento-A may play improvement effect on damp-heat UC rats by regulating immune system balance and reducing inflammatory damage.
