ABSTRACT
Objective:To compare the analgesic effects of naborphine and desorine after surgery for supracondylar fracture of humerus in children.Methods:Eighty-seven children with supracondylar fracture of humerus who received surgical treatment in Zhoushan Hospital of Traditional Chinese Medicine between January 2019 and January 2020 were included in this study. They were randomly assigned to receive postoperative analgesia either with dezocine (control group, n = 44) or naborphine (observation group, n = 43). The postoperative agitation score, postanesthetic recovery score, postoperative visual analogue scale score, and adverse reactions were determined between the two groups. Results:The heart rate and mean arterial pressure at the time of extubation were (102 ± 7) beats/min and (83 ± 6) mmHg respectively in the observation group, which were significantly lower than those in the control group [(115 ± 8) beats/min, (92 ± 7) mmHg, t = 6.214, 8.283, P < 0.05]. In the observation group, the postoperative agitation score was (4.45 ± 0.34) points, (5.02 ± 0.38) points, and (3.65 ± 0.39) points, at the time of spontaneous eye opening, at the time of extubation and at 30 minutes after extubation respectively, which were significantly lower than those in the control group [(5.31 ± 0.48) points, (5.75 ± 0.35) points, (4.12 ± 0.37) points, t = 6.392, 7.194, 7.382, all P < 0.05]. At 30 min, 3 h and 6 h after surgery, the visual analogue scale scores in the observation group were significantly lower than those in the control group ( t = 5.345, 6.124, 7.553, P < 0.05). The time to return to spontaneous breathing, the time to spontaneous eye opening and the time to extubation in the observation group were (7.32 ± 4.17) min, (11.65 ± 3.32) min, (12.13 ± 2.41) min, respectively, which were significantly shorter than those in the control group [(10.34 ± 4.15) min, (14.43 ± 3.18) min, (15.16 ± 2.23) min, t = 7.216, 5.382, 7.319, all P < 0.05]. The incidence of adverse reactions in the observation group was significantly lower than that in the control group [6.97% (3/43) vs. 27.27% (12/44), χ2 = 6.280, P < 0.05]. Conclusion:Naborphine for analgesia after surgery for supracondylar fracture of humerus in children can effectively reduce the incidence of agitation during the recovery period, enhance postoperative analgesic effect, and lower the incidence of reverse reactions.
ABSTRACT
Objective:To investigate the postoperative analgesic efficacy of nabuprofen combined with femoral nerve block in older adult patients subjected to knee arthroplasty and its effects on cognitive function and serum S-100β protein level.Methods:Ninety-one older adult patients subjected to knee arthroplasty between March 2018 and March 2020 in Zhoushan Hospital of Traditional Chinese Medicine were included in this study. They were randomly divided into observation ( n = 45) and control ( n = 46) groups. Patients in both groups received femoral nerve block and catheterization. Naborphine and equal amount of 0.9% sodium chloride injection were intravenously administered in the observation and control groups, respectively for postoperative analgesia. Before and after surgery, Mini-Mental State Examination (MMSE) score, S-100β protein level and Visual Analogue Scale score, and adverse reactions were compared between the observation and control groups. Results:Before surgery, there was no significant difference in MMSE score between the two groups ( P > 0.05). At 3 days after surgery, MMSE score in each group was significantly decreased compared with before surgery (both P < 0.05). At 3 days after surgery, MMSE score in the observation group was significantly higher than that in the control group [(25.34 ± 1.31) points vs. (23.67 ± 1.53) points, t = 5.34, P < 0.05]. Before surgery, there was no significant difference in serum S-100β protein level between the two groups ( P > 0.05). At 1 and 3 days after surgery, serum S-100β protein level in each group was significantly increased compared with before surgery (both P < 0.05). At 7 days after surgery, serum S-100β protein level in each group recovered to pre-operative level. At 1 and 3 days after surgery, serum S-100β protein level in the observation group was significantly lower than that in the control group ( t = 10.20, 9.21, both P < 0.05). At 1, 3, 6, 12 and 24 hours after surgery, the Visual Analogue Scale score in the observation group was (1.14 ± 0.22) points, (1.43 ± 0.25) points, (1.87 ± 0.21) points, (3.56 ± 0.20) points, and (2.63 ± 0.23) points respectively, which was significantly lower than that in the control group [(2.53 ± 0.24) points, (2.53 ± 0.24) points, (3.56 ± 0.20) points, (3.98 ± 0.25) points, (4.23 ± 0.21) points, t = 5.10, 8.15, 9.41, 10.18, 11.42, all P < 0.05]. The incidence of adverse reactions in the observation group was significantly lower than that in the control group [13.33% (6/45) vs. 30.43% (14/46), χ2 = 3.88, P = 0.049]. Conclusion:Naborphine combined with femoral nerve block can effectively improve the postoperative cognitive function of older adult patients undergoing knee arthroplasty, provides good postoperative analgesia, and is highly safe.

ABSTRACT
Objective To investigate effects of drugs on spermatogenesis following testicular ischemia-reperfusion in rats. Methods Healthy male Sprague-Dawley rats ( n = 32) were randomly divided into four groups, 8 rats in each group. Animals underwent unilateral testicular torsion followed by detorsion after 2 hours. Isotonic saline, pentoxifylline and verapamil were infused into tail vein 15 minutes before detorsion in torsion group, pentoxifylline group and verapamil group. At 24 hours after operation, testicular function was determined measuring germ cell apoptosis using the flow cytometry ( FCM) , and the levels of myeloperoxidase ( MPO) , superoxide dismutase (SOD) and malondialdehyde (MDA) by spectrophotometry. Results Compared with torsion group, the number of apoptotic germ cell and the contents of MDA and MPO were markedly decreased in pentoxifylline group and verapamil group, but the number of haploid and the level of SOD were significantly increased (P
ABSTRACT
<p><b>OBJECTIVE</b>To study the relationship between the apoptosis and the expression of inducible nitric oxide synthase (iNOS) and Bcl-2 in prostate carcinoma (PCa).</p><p><b>METHODS</b>Expression of Bcl-2 and iNOS and apoptotic cells in 24 cases of PCa, 15 cases of BPH and 5 cases of normal prostate tissues were detected by immunohistochemical technique and terminal-deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL), respectively.</p><p><b>RESULTS</b>Apoptosis index (AI) and iNOS-positive index of PCa were much higher than that of the benign prostate hyperplasia (BPH) and the normal prostate group(P < 0.01). The AI of the Bcl-2-positive group was lower than that of the negative ones in PCa(P < 0.01).</p><p><b>CONCLUSIONS</b>AI might serve as a marker in evaluating the aggression of PCa. The iNOS-positive index of PCa had no relationship with the differentiated grades but had a negative relationship with the expression of Bcl-2. The expression of Bcl-2 protein was negatively related to PCa cell apoptosis. Both iNOS and Bcl-2 were believed to play roles in the pathogenesis and development of PCa by influencing the cell apoptosis.</p>

<p><b>OBJECTIVE</b>To investigate the restoration of erectile function by reconstructing cavernous nerves with sural nerve grafts.</p><p><b>METHODS</b>Forty-eight male Sprague-Dawley rats(3-4 m old and 300-400 g) were randomly divided into three groups: the sham-operated group (n = 16) underwent pelvic exploration without transection of the cavernous nerve; the nerve ablation group (n = 16) had a 5 mm segment of the cavernous nerve excised bilaterally; the graft group (n = 16) had a 5 mm segment of the cavernous nerve excised bilaterally, followed by immediate microsurgical reconstruction with an interposition graft of the sural nerve. The cavernous nerves of each group were electrostimulated to determine their potency after 2 and 4 months. And fluorescent retrograde-transported material Fluoro-Gold(FG) was injected into the penis. FG-labeled neuron cells in whole mounts of major pelvic ganglions were observed five days after injection.</p><p><b>RESULTS</b>Electrical stimulation produced no erection in either the nerve ablation or the graft group, but 100% erection in the sham-operated group after 2 months. The numbers of FG-labeled neurons significantly differed between the nerve ablation group and the graft group. After 4 months erection examination showed statistical significance in the difference between the graft group and the nerve ablation group(P < 0.05). The FG-labeled neurons in the graft group significantly differed from those in the ablation (P < 0.05), and almost reached the level of the sham-operated(P < 0.05).</p><p><b>CONCLUSION</b>Cavernous nerve grafting can successfully restore erectile dysfunction in rats after surgical injury.</p>

Objective To evaluate the reconstruction of bladder using a segmental sinus-body of stomach on the basis of a clinical study.Methods We retrospectively reviewed the medical records,laboratory evaluations,imaging examinations,cystoscopy,urodynamic studies of 30 patients(17 men and 13 women;mean age,55 years;age range,21-69 years) who underwent the reconstruction of bladder using a segmental sinus-body of stomach.Of the 30 patients,24 had primary bladder cancer and 6 had tuberculous contracture of the bladder.Results After operation,the new gastric bladder worked well in keeping and emptying urine.All patients micturated through the urethra.The bladder capacity was 280-580 ml(mean,385 ml).The maximum urethral pressure was 20-60 cm H_2O(mean,49 cm H_2O).The filling bladder pressure was 5-15 cm H_2O(mean,12 cm H_2O).The maximum bladder pressure was 35-65 cm H_2O(mean,55 cm H_2O),and it was 28-60 cm H_2O(mean,46 cm H_2O) during urination.Qmax and post-void residual urine were 10-28 ml/s(mean,18 ml/s) and 5-85 ml(mean,20 ml),respectively.Follow-up ranged from 9 months to 24 years(mean,8.2 years).There were no disturbance of water and electrolyte metabolism,no vesicoureteral reflux,no uracratia,and no damage to renal function.Complications included perineal and vesical pain in 4 cases,enuresis in 5 cases,which gradually remitted 3-6 months after surgery,and bladder stone formation in 1 case,who underwent surgery again.At 3.5 years after surgery bladder tumor relapsed in 1 case,who then underwent transurethral resection of bladder tumor. Conclusions Our data show that the substitution of a segmental sinus-body of stomach for urinary bladder worth popularizing because of low complication rate and approximately normal urologic indexes.
ABSTRACT
Objective To investigate the feasibility of repairing surgically ablated cavernous nerves with silastic nerve tube conduit filled with nerve growth enhancing media. Methods 54 male adult Sprague-Dawley rats were randomized into 3 groups,the sham operated controls,the bilateral cavernous nerve ablation and entubulization nerve reconstruction with insulin like growth factor(IGF).1,3 and 6 months after surgery,rats models were evaluated with apomorphine test,followed by nicotinamide adenine dinucleotide phosphate (NADPH) diaphorase staining to identify NOS in penile nerve fibers of the proxiamal portion of penile shaft and penile crus. Results There was no statistically significant difference between the ablated and the entubulization nerve reconstruction groups at 1 month,however,at 3 and 6 months,Apomorphine test studies resulted in tumescence from 42% and 50% of the entubulization nerve reconstruction groups versus 0% and 0% of the ablated group,respectively (P
ABSTRACT
Objective To study the relationship of epithelial nitric oxide synthase (eNOS) expression with the germ cell development and apoptosis in the rat cryptorchid. Methods Germ cell apoptosis was detected by terminal deoxynucleotidyl transferase mediated d UTP nick end labeling (TUNEL) in the unilateral cryptorchid.Expression of eNOS was detected by immunohistochemical S P method. The dispersion characteristics of expression of eNOS mRNA was investigated by in situ hybridization. Results On the 7th day after the operation,as compared to the control,the number of apoptotic germ cell in the cryptorchid was increased significantly,but its testis weight was decreased predominantly,and expression of eNOS gene was localized to the cytoplasm of Legdig cell,Sertoli cell and germ cell in both testes.On the 40th day,expression of eNOS gene was localized to the cytoplasm of lengthened spermid.On the 3rd day and 7th day,expression of eNOS mRNA had no apparent change in the cryptorchid as compared to the control. Conclusions In adolescence,expression of eNOS regulates secretion of hormone and germ cell development;whereas after adulthood,expression of eNOS is only related to the mature and activity of sperm.Expression of eNOS has no apparent relationship with germ cell apoptosis.
ABSTRACT
Objective To investigate the mechanism of contralateral testicle spermatogenesis impairment following unilateral testicular torsion in rats.Methods Healthy male Sprague-Dawley rats(n=24) were randomly divided into 3 groups:group 1(sham-operation),2 and 3,each comprising 8 rats.Under surgical conditions,the left testes of the rats in groups 2 and 3 were rotated through clockwise 720? torsion,then detorsion after 12 h or 24 h,respectively.The contralateral testes were harvested after 1 month and the relative proportions of germ cells were measured by the flow cytometry(FCM).Anti-rat immunoglobulin G(IgG)antibodies against spermatozoa antigens were detected in contralateral testicular tissue by immunohistochemical method.Results In groups 1,2 and 3,the weight of contralateral testis was(1555.73?(72.34)),(1184.20?101.02) and(783.60?117.93)mg,respectively;the number of apoptotic cells was 53.25?8.61,1622.00?129.31 and 3401.25?179.75,respectively;the positive rates of antisperm antibodies were 0,0.55?0.02 and 0.69?0.03,respectively.There were significant differences in above parameters between groups(P
ABSTRACT
ObjectiveTo investigate the feasibility of repairing surgically ablated cavernous nerves by using an interposition genitofemoral nerve graft and with nerve growth enhancing media (insulin-like growth factor-I,IGF-I) injection.MethodsA total of 54 male adult Sprague-Dawley rats were randomly divided into 3 groups (each of 18 rats),including sham operation controls, bilateral cavernous nerve ablation and nerve graft with IGF-I injection groups.At 1,3 and 6 months after surgery, the rat models were evaluated with Apomorphine Test.Then nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) staining was used to identify nNOS in penile nerve fibers of the proximal portion of penile shaft.ResultsAt 1,3 and 6 months after surgery, the rats of sham operation group had normal erectile function (erection rate,100%),while the rats of nerve ablation group lost erectile function at all (erection rate,0%).There was no statistically significant difference of ED between the nerve ablation and nerve graft groups at 1 month;however,at 3 and 6 months,Apomorphine Test resulted in tumescence of 50% and 66.7% of the nerve graft groups vs 0% and 0% of the nerve ablation groups, respectively ( P
