ABSTRACT
Objective To detect the feasibility and safety of applying all-seeing needle in transurethral seminal vesiculoscopy.Methods Retrospective analysis was made with clinical data of 32 patients of hemospermia treated with transurethral seminal vesiculoscopy using all-seeing needle from March 2016 to January 2018.The patients'age was (38.8 ± 8.7) years (27-60 years) and the course of disease was (7.1 ±3.3) months (2-15 months).Ultrasound before operation showed heterogeneous echo,or expansion of the seminal vesicle.MRI showed hemorrhage of the seminal vesicle,or abnormal signal of the seminal vesicle.Patients had levofloxacin or mosisasin anti-infection therapy more than one month and remained uncovered.The operation was performed under subarachnoid anesthesia,and the patients took the lithotomy position.The F4.8 all-seeing needle entered the posterior urethra,the verumontanum was found,and the saline was slowly pushed with a syringe to maintain a clear view.Then,the ejaculatory duct opening was searched on both sides of the verumontanum.If the ejaculatory duct opening cannot be found in the normal position,we entered the needle into the prostatic utricle to find the possible ectopic opening.If the ejaculatory duct opening was still not found,at the 5 and 7 o'clock positions in the prostatic utricle,the needle was probed and punctured into the side wall of the ejaculatory duct.Visible puncture with all-seeing needle can effectively avoid penetrating blood vessels and reduce damage to tissues during puncture.In this study,the ejaculatory duct opening got accessed on the verumontanum in 14 cases,through ectopic openings within the prostatic utricle in 2 cases,and through artificial establishment in 5 and 7 o'clock positions within prostatic utricle in 16 cases.After entering the ejaculatory duct and seminal vesicle,we explored the cavities of the seminal vesicles.For stones or polyps,after replacing the outer sheath to F8,F1.9 stone retrieval basket was applied to remove stones or polyps,followed by rinsing the seminal vesicles with normal saline,0.02％ nitrofurazone,and then 160,000 units of gentamicin into each seminal vesicle.For hemorrhage,after clearing up the blood,seminal vesicles were also washed with normal saline,nitrofurazone,and perfused with gentamicin.In the operation,prostatic utricle stone was found in 5 cases,and seminal vesicle stone was found in 7 cases.One case of seminal vesicle polyp was observed,and in 19 cases,seminal vesicle hemorrhage was seen.Results All the operations were accomplished successfully,the operation time was (55.0 ± 11.3) min (35-82 min).There was no rectal injury or urethral injury during operation.The postoperative catheter was removed at 2 days postoperatively and the patients discharged on the 4th day after surgery.The length of hospital stay was (6.3 ± 0.7) days (5-7 days).One patient had mild hematuria after removal of the urethral catheter and got improved spontaneously;one case developed epididymitis,which improved after anti-infective treatment.6 cases made stone analysis,with 5 cases of magnesium ammonium phosphate hexahydrate,and 1 case of calcium oxalate dihydrate,calcium oxalate monohydrate and carbonate apatite mixed stones.One case of polyp was diagnosed by pathologists to be an inflammatory polyp.Follow-up was performed at 4,6,8,and 12 weeks after surgery.Hemospermia was cured in 24 cases,relieved in the other 8 cases at 8-week follow-up,who received oral antibiotic treatment afterwards.At the 12-week follow-up,the rest 6 cases in 8 got hemospermia recovered,with 2 cases still uncovered.Conclusions All-seeing needle is user-friendly and safe in transurethral seminal vesiculoscopy,with reliable short-term efficacy.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the changes of ID1 expression in tumor cells treated with etoposide, cisplatin and ultraviolet (UV) irradiation, and explore the effect of ID1 on chemotherapeutic drug- and UV-induced apoptosis.</p><p><b>METHODS</b>In the present study, upon onset of apoptosis induced by various kinds of inducers such as etoposide, cisplatin and UV irradiation, the expression level of ID1 was detected by Western blot and real-time PCR. We also analyzed the half-life of ID1 protein and stability of ID1 mRNA respectively by cycloheximide inhibition test and RT-PCR. Annexin-V assay was carried out to evaluate the contribution of ID1 protein to chemotherapeutic drug- and UV-induced apoptosis.</p><p><b>RESULTS</b>ID1 expression presented a profound down-regulation in the HCT116 cells treated with etoposide, cisplatin and UV irradiation(P<0.05 for all). The apoptosis in the UV irradiation group, cisplatin group, etoposide group was (58.70±1.55)%, (35.80±0.92)% and (21.00±0.72)%, respectively, significantly higher than that of the control group(1.10±0.07)%, (1.20±0.13)% and (3.50±0.23)% (P<0.05 for all). Upon etoposide treatment, ID1 expression level was decreased via induction of mRNA instability, but not the protein degradation changes. Additionally, ectopic expression of ID1 in the HCT116 cells alleviated etoposide-, cisplatin- and UV-induced apoptosis. The results of flow eytometry revealed that the percentage of apoptotic cells in the ID1 group under the treatment of etoposide, cisplatin and UV irradiation was (23.80±0.82)%, (17.80±1.34)% and (13.40±0.53)%, respectively, significantly lower than that in the empty vector group (41.10±1.61)%, (30.40±2.67)% and (22.50±3.47)% (P<0.05 for all).</p><p><b>CONCLUSIONS</b>These observations indicate that the treatment with etoposide reduces the amount of ID1 by induction of mRNA instability, and exogenously introduced ID1 protects cells against etoposide-, cisplatin- and UV irradiation-induced apoptosis. Inhibition of the ID1 bioactivity may become a new strategy in cancer treatment.</p>

Objective To study the influence of sole massage on children’s analepsia from general anesthesia.Methods One hundred children in analepsia period were divided into the test group(50 cases)and the control group(50 cases).The routine nursing and monitoring during recovery stage were done in the control group.Based on the routine monitoring and nursing care as in the control group,the test group received sole massage for 10 minutes.The two groups were compared in terms of declining percentage of SpO2, rate of nausea,blood pressure,heart-rate variability,and post-analepsia dysphoria scores.Result The test group was significantly lower than the control one in all the indexes of the declining percentage of SpO2,rate of nausea,blood pressure,heart-rate variability,and post-analepsia dysphoria scores(all P<0.05).Conclusions Sole massage during children’s analepsia from general anesthesia is effective not only in lessening their declining percentage of SpO2,rate of nausea,blood pressure,heart-rate variability, and recovery dysphoria mark,but also easing their dysphoria,anxiety and fear.It may create a good condition for children to live through analepsia period successfully and safely.
ABSTRACT
Objective To study the expression of signal transducer and activator of transcription 1 (STAT1) in human renal clear cell carcinoma (RCC) and the effect of STATI inhibition on the radiosensi-tivity of RCC. Methods The expression of STAT1 in 34 human RCC samples compared with 12 normal kid-ney tissues was examined by immunohistochemistry method. For in vitro experiments, a human RCC cell line, CRL-1932, was used. Western blotting was performed to evaluate the expression of total and phospory-lated STAT1. Fludarabine and siRNA were respectively used to inhibit the expression of STAT1 in CRL-1932 cells. Clonogenic assay and trypan blue staining assay were used to evaluate the radiosensitivity of CRL-1932 cells. Results The expression of both total and phospborylated STAT1 in human RCC samples was signifi-cantly higher when compared to normal kidney tissues. Similarly, the expression of STAT1 was higher in CRL-1932 cells when compared to fibroblast and Wilm's tumor cell lines. STAT1 expression was inhibited by both fludarabine and siRNA. Radiosensitivity of CRL-1932 cells was enhanced by both fludarabine and siRNA induced STAT1 inhibition. Conclusions STAT1 is over-expressed in both human RCC tissue and cell line. Inhibition of STAT1 can enhance the radiosensitivity of RCC cells.
ABSTRACT
<p><b>BACKGROUND</b>To study the effects of huTNF-α and hIL-2 gene transfection on the expression of MDR1 and LRP genes in lung cancer cell lines.</p><p><b>METHODS</b>huTNF-α and hIL-2 gene plasmids were constructed and transfected into A549, GLC-82, H446 and H460 cells with lipofectinmin. Positive clones were screened out by G418. The expressions of MDR1 and LRP genes were detected at mRNA level by reverse transcription polymerase chain reaction (RT-PCR) in the non transfected cells and the cloned cells.</p><p><b>RESULTS</b>MDR1 gene was positive in A549, GLC-82, H446 and H460 cell lines, LRP gene was positive in A549, GLC-82 and H460 cell lines; The transfected cell lines expressed both huTNF-α and hIL-2 gene, and the A549, H446 and H460 cell lines transfected with hIL-2 gene had no MDR1 expression at mRNA level compared with the non transfected ones.</p><p><b>CONCLUSIONS</b>MDR1 and LRP genes are expressed in lung cancer cell lines, which indicates the presence of intrinsic drug resistance before any form of therapy. MDR1 gene is not expressed in hIL-2 transfected cell lines, which demonstrates that hIL-2 gene modulates the MDR1 gene expression at mRNA level, and may reverse the multidrug resistance of lung cancer.</p>
