1.Changes of acetylcholine receptor in skeletal muscle after upper motoneuron injury and the regulation of calcitonin gene related peptide
Chinese Journal of Anesthesiology 1997;0(11):-
Objective To observe the time profile of the changes of mRNA of ? and ? subunit of acetylcholine receptor (AChR) in skeletal muscle and the level of calcitonin gene related peptide (CGRP) in spinal motoneuron after upper motoneuron injury. Method The spinal cord of adult male Wistar rats was transected on the lower thoracic segment. The spinal cords below the transection level and soleus muscles were sampled 0,1,2,4,7 and 14 days after surgery, respectively, to detect the levels of mRNA of ? and ? subunit of acetylcholine receptor in soleus muscle using Northern blot method,and CGRP level in spinal motoneuron using radioimmunoassay.Results The levels of mRNA of ? and ? subunit of acetylcholine receptor siginificantly increased after surgery, but the level of mRNA of ? subunit increased earlier and higher than ? subunit. The level of CGRP in spinal motoneuron markedly reduced after surgery, was maintained at 50 80% of normal level since the 2nd day after surgery. Conclusions The levels of AChR ? and ? subunit in skeletal muscle significantly increase after upper motoneuron injury, the expression of which CGRP may regulate.

China Medical Equipment 2017;14(3):141-146
PET-CT, SPECT, and SPECT-CT examinations could lead to inevitable medical exposure for patients, and the radiation dose of this examinations and whether it was harmful to patients have attracted attention from the public and professionals. At the same time, there was still a controversy about whether the biological effect of low dose radiation was useful to human body. The research investigates and reviews the radiation dose of PET-CT, SPECT, and SPECT-CT scans and their biological effects. Under achieved to the demands of clinical conditions, operators should try to reduce the radiation dose of PET-CT, SPECT, SPECT-CT scans for patients. Although PET-CT, SPECT, SPECT-CT scans deliver inevitable radiation, the dose of single examination will not lead to deterministic effect, and even the view of the random effect of linear no-threshold from these scans also have been questioned.

China Medical Equipment 2017;14(1):117-121
Whole-body PET-CT scanning has been used in the diagnosis and treatment of tumor to providing functional and morphological imaging. As the most widely used semi-quantitative analysis index, the cutoff value of SUV would affect the final diagnosis, therapeutic regimen and prognosis estimation. Therefore, the article reviews the influential factors of SUV, its correction methods, its cutoff values of differential various tumors and the progress of SUV. Although there is no acknowledged cutoff value of SUV in tumor diagnosis, SUV is still an important semi-quantitative index, and its rational and prudent use would increase both of the sensitivity and specificity in tumor diagnosis.

Objective To study the complications and their management of plasmakinetic transurethral resection of the prostate (PKRP). Methods Complications and their management of 51 cases of PKRP from May 2003 to June 2006 were retrospectively reviewed. Results Complications of the procedure were as follows. Bladder spasms occurred in 27 cases (accompanying hemorrhage in 2 cases and urge incontinence in 6 cases), and the symptoms disappeared after patient-controlled intravenous analgesia and M-receptor blocker (tolterodine). Postoperative bleeding occurred in 6 cases. Continuous irrigation with normal saline and medical therapy were given in 3 cases, and open surgery was required in 3 cases with severe bleeding. All bleeding patients obtained a full recovery of voiding function without re-bleeding. Urge incontinence occurred in 13 cases, and was cured with functional exercises of pelvic floor muscles and M-receptor blocker (tolterodine) administration. Stress incontinence was observed in 1 case, and a penile clamp had been used to control incontinence. Among 7 cases of urinary retention after operation, a re-operation of PKRP was conducted in 2 cases and oral medication was carried out in 5. The voiding function recovered well in all the 7 cases. In 5 cases of urethral stricture, urethral dilatation was employed in 3 cases and urethrotomy was performed in 2 cases to obtain a good recovery of voiding function. Conclusions Bladder spasm, postoperative bleeding, incontinence, urinary retention, and urethral stricture are common complications of PKRP. Strict adherence to technique and timely and proper management of complications are considered essential to improve results.
