ABSTRACT
The aim of this study was to explore the optimal timing of holmium laser enucleation of the prostate (HoLEP) in patients presenting benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS). A retrospective analysis was conducted based on the perioperative and postoperative outcome data of 1212 patients who underwent HoLEP in Shanghai Ninth People's Hospital (Shanghai, China) between January 2009 and December 2018. According to the preoperative International Prostate Symptom Score (IPSS), all patients whom we analyzed were divided into Group A (IPSS of 8-18) and Group B (IPSS of 19-35). Peri- and postoperative outcome data were obtained during the 1-year follow-up. IPSS changes were the main postoperative outcomes. The postoperative IPSS, quality of life, peak urinary flow rate, postvoid residual, and overactive bladder symptom score (OABSS) improved significantly. The IPSS improved further in the group with severe LUTS symptoms, but the postoperative IPSS was still higher than that in the moderate LUTS group. OABSSs showing moderate and severe cases after follow-up were more frequent in Group B (9.1%) than in Group A (5.2%) (P < 0.05). There were no significant intergroup differences in the intraoperative American Society of Anesthesiologists or hospitalization expense scores, and the medication costs, as well as the total costs, were significantly higher in Group B. In this retrospective study, HoLEP was an effective treatment for symptomatic BPH. For patients with LUTS, earlier surgery in patients with moderate severity may result in a marginally better 12-month IPSS than that in men with severe symptoms.

Objective@#To evaluate the safety and clinical efficiency of holmium laser enucleation of the prostate (HoLEP) in the treatment of small-volume BPH (SBPH) complicated by severe lower urinary tract symptoms (LUTS).@*METHODS@#We retrospectively analyzed the clinical data on 82 cases of SBPH with severe LUTS treated by HoLEP from January 2017 to December 2018. The patients were aged (65.5 ± 7.6) years, with a mean prostate volume of <40 ml, a total IPSS of 24.8 ± 4.6, a QOL score of 5.2 ± 0.8, the maximum urinary flow rate (Qmax) of (7.6 ± 3.7) ml/s, and a mean PSA level of (1.8 ± 1.4) μg/L.@*RESULTS@#All the operations were successfully completed, the mean operation time averaging (30.2 ± 5.0) min, enucleation time (26.7 ± 5.6) min and comminution time (3.5 ± 1.1) min, and the enucleated tissue weighing (20.3 ± 4.9) g. After surgery, the bladders were irrigated for (3.5 ± 1.9) h, with (3.0 ± 1.7) L of rinse solution, and catheterization lasted (24.8 ± 9.7) h. Histopathology revealed moderate or severe lymphocytic infiltration in 69 cases (84.1%). At 6 months after operation, significant improvement was observed in the IPSS, QOL, Qmax and PSA level compared with the baseline (P < 0.05). To date, no urethral stricture-related reoperation was ever necessitated.@*CONCLUSIONS@#HoLEP is safe and effective for the treatment of SBPH complicated by severe LUTS and can be employed after adequate preoperative evaluation of the patient.《.

We report the clinical characteristics, treatments and outcomes of 4 rare cases of mixed amanita fuliginea and amanita rimosa poisoning with rhabdomyolysis, and review the research progress in the intoxication mechanism and treatment. The latent time of amanita poisoning, defined as the period from the ingestion of poisonous mushroom to the onset of gastrointestinal symptoms, was about 8 days, and the severity of poisoning was associated with the amount of mushroom ingested. All the 4 patients developed multiple organ dysfunctions within 3 to 4 days after mushroom ingestion, predominantly in the liver, kidney and central nervous system accompanied with acute gastrointestinal injury and rhabdomyolysis. The treatment measures included persistent hemofiltration and intermittent hemoperfusion once daily for 5-7 days, and plasma exchange was administered in 2 cases for 1 or 2 times. High-dose vitamin C, glucose and corticosteroid were also given to the patients. After the treatments, two patients were cured and the other two died due to an excess intake of poisonous mushroom and lack of early preemptive therapies. Early emetic, gastric lavage, catharsis, fluid infusion and diuresis are critical to interrupt the enterohepatic circulation of amanita phalloides toxins and prevent the development of multiple organ dysfunction. Enhanced hemofiltration and sequential plasma therapy might effectively eliminate toxin from the blood to protect against further organ damages.
ABSTRACT
Objective@#To compare the safety and effectiveness of shovel-shaped electrode transurethral plasmakinetic enucleation of the prostate (PKEP) with those of plasmakinetic resection of the prostate (PKRP) in the treatment of benign prostatic hyperplasia (BPH).@*METHODS@#We retrospectively analyzed the clinical data about 78 BPH patients received in Shanghai Ninth People's Hospital from June 2016 to January 2017, 39 treated by shovel-shaped electrode PKEP and the other 39 by PKRP. We observed the patients for 6 months postoperatively and compared the effects and safety of the two surgical strategies.@*RESULTS@#No statistically significant difference was observed between the PKEP and PKRP groups in the operation time ([69.3 ± 8.8] vs [72.2 ± 7.9] min, P = 0.126), but the former, as compared with the latter, showed a markedly less postoperative loss of hemoglobin ([3.9 ± 2.8] vs [13.9 ± 5.2] g/L, P 0.05) and other postoperative complications.@*CONCLUSIONS@#Both PKEP and PKRP are effective methods for the treatment of BPH, but PKEP is worthier of clinical recommendation for a better safety profile, more thorough removal of the prostate tissue, less blood loss, shorter hospital stay, and better improved quality of life of the patient.

Objective@#To investigate the clinical effect of "3+1" bladder function restoration combined with holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH) with acontractile detrusor (ACD).@*METHODS@#We treated 35 BPH patients with ACD by HoLEP followed by "3+1" bladder function restoration, that is, a 3-phase bladder function training plus simultaneous 1-drug medication after surgery. We recorded and analyzed the detrusor pressure, post-void residual urine volume (PVR), maximum urinary flow rate (Qmax), International Prognostic Scoring System (IPSS) scores, quality of life (QoL), voluntary micturition, satisfaction with the bladder function, hydronephrosis, ureterectasia, renal function, and urinary tract infection of the patients before and after treatment.@*RESULTS@#Compared with the base line, at 6 months treatment, the patients showed significantly increased detrusor pressure ([35.1±2.7]vs [50.2±2.3] cmH2O, P<0.05) and Qmax ([4.2±2.7]vs [21.1±4.1] ml/s, P<0.05) but decreases in PVR ([173.0±31.6] vs [30.5±12.9]ml, IPSS score (27.3±3.2 vs 5.1±1.4, P<0.05) and QoL (4.1±0.8 vs 0.8±0.1, P<0.05), elevated rates of voluntary urination (0% [0/35] vs 100% [35/35], P<0.05), regularurination (0% [0/35] vs 85.71% [30/35], P<0.05), grade Ⅰ satisfaction with bladder function (0% [0/35] vs 85.71% [30/35], P<0.05), reduced rate of overflowing urinary incontinence (28.57% [10/35] vs 5.71% [2/35], P<0.05), and increased percentages of normal renal function (34.29% [12/35] vs 85.71% [30/35], P<0.05) and non-infection of the urinary system (17.14% [6/35] vs 94.29% [33/35], P<0.05). After treatment, urination was markedly improved in 94.29% (33/35) of the patients.@*CONCLUSIONS@#"3+1" bladder function restoration combined with HoLEP produced a desirable effect on BPH with ACD, though its long-term effect remains to be further investigated.

<p><b>Objective</b>To evaluate the efficiency and safety of the modified versus conventional morcellation procedure in holmium laser enucleation of the prostate (HoLEP).</p><p><b>METHODS</b>We treated 195 patients with benign prostatic hyperplasia (BPH) by HoLEP, using conventional morcellation for 100 cases and modified morcellation for the other 95. We recorded the morcellation time, the total volume of resected tissue, the rate of morcellation, and associated complications, and compared the data obtained between the two groups.</p><p><b>RESULTS</b>The volumes of resected tissue were similar between the conventional and modified morcellation groups ([72.3±19.8] vs [71.1±17.7] g, P>0.05). The morcellation time was significantly longer in the conventional than in the modified morcellation group ([12.8±2.8] vs [8.5±2.0] min, P<0.01), and the morcellation rate was remarkably lower in the former than in the latter ([4.9±1.4] vs [7.1±0.9] g/min, P<0.01). No statistically significant differences were observed in the incidence of complications, bladder injury for instance, between the two groups of patients.</p><p><b>CONCLUSIONS</b>The modified morcellation procedure can be used for mocellation of various types of tissue, with a higher efficiency than the conventional technique, and therefore deserves wide clinical application.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the safety and effectiveness of a modified method of holmium laser enucleation of the prostate (HoLEP)--6-o'clock tunnel HoLEP for the treatment of benign prostate hyperplasia (BPH).</p><p><b>METHODS</b>We included 112 cases of BPH in this study, 57 treated by 6-o'clock tunnel HoLEP (experimental group) and the other 55 by conventional HoLEP (control group). We compared the operation time, volume of the resected prostatic tissue, intraoperative blood transfusion, volume of bladder irrigation solution, postoperative hemoglobin change, and incidence of urinary incontinence between the two groups.</p><p><b>RESULTS</b>Statistically significant differences were observed between the experimental and control groups in the operation time ([56.01 ± 8.62] min vs [68.65 ± 9.08] min), cases of intraoperative blood transfusion (0 vs 2), volume of bladder irrigation solution ([27.51 ± 3.67] L vs [36.89 ± 6.47] L), postoperative hemoglobin decrease ([10.70 ± 2.50] g/L vs [12.60 ± 3.30] g/L), and cases of postoperative stress-induced urinary incontinence (2 vs 7) (all P <0.05). One-month follow-up revealed smooth urination in both groups of patients but no true urinary incontinence or secondary bleeding in either.</p><p><b>CONCLUSION</b>Modified 6-o'clock tunnel HoLEP can significantly reduce the operation time, bladder irrigation, and intraoperative bleeding, and therefore can be used as a safe and effective option for the treatment of BPH.</p>

<p><b>BACKGROUND</b>The consumption of carbohydrate-electrolyte beverages (CEs) has been known to be more effective than plain water for recovery from dehydration. This phenomenon suggests that the ingestion of CEs after dehydration is better than water for maintaining body fluid and plasma volume, and for the recovery from hemoconcentration and high blood viscosity as well. High blood viscosity causes infarction and other cardiovascular events. In this study, CE was compared with water and tea for the ability to reduce increased blood viscosity after dehydration.</p><p><b>METHODS</b>A crossover random control study was conducted to assess the effectiveness of three beverages for rehydration and decreasing of blood viscosity. Following exercise-induced dehydration of 2.2% of body weight in a permanent warm environment, 10 male subjects rested in a thermoneutral environment for 3 hours (rehydration period, REP). The subjects ingested test beverages equal to their body weight loss during the first 20 minutes in REP. Blood and urine samples were obtained throughout the experiments to assess the rehydration effect.</p><p><b>RESULTS</b>The change in blood viscosity at a shear rate of 5/s was significantly lower in CE ((-1.66 ± 0.21) mPa×s) in comparison to water ((-0.95 ± 0.26) mPa×s) or tea ((-0.92 ± 0.14) mPa×s) at 60th minute during the REP. The fluid retention rate was significantly greater for CE ((77.0 ± 3.9)%) than water ((61.2 ± 3.4)%) and tea ((60.5 ± 3.7)%) for 3 hours of rest in REP.</p><p><b>CONCLUSIONS</b>The recovery from high blood viscosity induced by dehydration was higher with CE consumption than with water or tea. These results suggest that CE is useful for normalizing increased blood viscosity due to exercise-induced dehydration.</p>

<p><b>OBJECTIVE</b>To explore the association between monoamine oxidase A (MAOA) variable number tandem repeat (VNTR) polymorphism and major depression in Chinese Han population.</p><p><b>METHODS</b>Polymerase chain reaction was used to genotype MAOA VNTR polymorphism. A total of 512 major depression patients and 566 normal controls were recruited in our study. These patients were also assessed using the 14-item Hamilton anxiety scale. RESULTS The allele frequency of MAOA VNTR was not significantly different between the male/female major depression patients and the normal controls. Compared with the normal controls, MAOA VNTR genotype was significantly more frequent in female major depression patients (P=0.002), but not in male patients (P=0.17). MAOA VNTR-L carrier was also associated with "fear" symptom in female patients (P=0.0056).</p><p><b>CONCLUSION</b>MAOA gene is associated with the major depression in Chinese Han population, especially among female patients.</p>
