Introduction: Transurethral resection of the prostate (TURP) has been considered as the gold standard treatment for obstructive voiding dysfunction in men with benign prostatic hyperplasia. This standard treatment has been challenged by consistent data demonstrating the superiority of Holmium enucleation of the prostate (HoLEP). We review summarizes the literature comparing HoLEP to traditional therapies TURP, open prostatectomy (OP) for BPH these are widely used and have long term efficacy data. Patients undergoing HoLEP have significant shortened catheterization times, decreased length of hospital stay, fewer serious postoperative complications, greater reduction in post-operative IPSS, greater improvements in post-operative Qmax and lower rates of repeat endoscopic procedures for recurrent symptoms compared with TURP and OP. Furthermore, HoLEP can be used to resect more than 100 grams tissue and it is equivalent efficacy to open prostatectomy. Conclusion: HoLEP as the new gold standard treatment for surgical BPH therapy further. HoLEP remains its difficult learning curve when compared with traditional transurethral resection.

BACKGROUNDPeutz-Jeghers syndrome (PJS) is an autosomal dominantly inherited disease. STK11/LKB1 gene germline mutations have been identified as responsible for PJS. In our study, we investigated the molecular basis of PJS and evaluated correlation between the STK11 mutations and the Chinese population.

METHODSWe collected three pedigrees of PJS and screened the 9 exons and their flanking intronic sequences of STK11/LKB1 gene in the probands and normal individuals in the families using polymerase chain reaction (PCR) and direct sequencing.

RESULTSSequencing of the STK11 gene in the probands of 3 families revealed two novel mutations (c180C-->G and c998-1002delGCAGC) in exon 1 and exon 8, respectively. The mutation of c180C-->G resulted in a premature termination codon. The other mutation, a deletion of five nucleotides (998-1002delGCAGC) in exon 8, predicted to generate a translational frameshift and a termination at codon 1070.

CONCLUSIONSThe growing number of mutations in PJS pedigrees suggests the molecular basis of PJS. STK11 gene mutation can be detected in most patients with PJS.

OBJECTIVE: To study the characteristics of the diagnostic parameters of acute respiratory distress syndrome/multiple organ dysfunction syndrome on plateau (H-ARDS/MODS) and compare the accuracy of the three MODS scoring criteria in predicting the outcome of syndrome. METHODS: Five hundred and forty cases fulfilling the criteria of MODS were divided into four groups according to the altitude of their inhabitation area: control group (on plain, CG, n=113, altitude: <430 m), moderate high altitude group 1 (H1G, n=314, altitude: 1,517 m), moderate high altitude group 2 (H2G, n=78, altitude: 2,261 m to 2,400 m) and high altitude group (HG, n=35, altitude: 2 808 m to 3 400 m). According to the diagnostic criteria of Lushan conference and Marshall (1995) commonly used on plain, and Lanzhou criteria drafted by the authors, three data analyzing models were set up to draw the receiver operating characteristic (ROC) curves, the Yordon Index and the optimum cutoff points of the parameters were calculated and the accuracy of the three respective diagnostic criteria was evaluated in predicting the outcome of ARDS/MODS. Multiple factors affecting the outcome of MODS were analyzed using the method of stepwise forward regress model. RESULTS: Following the increase in altitude, Lanzhou criteria was clearly superior to the other two criteria in the area of ROC, the sensitivity, the specificity, and also for the optimum cutoff points of MODS. Multi-variable regression analysis showed that the impacting factor of Lanzhou criteria was the highest (P<0.05). CONCLUSION: (1)Some parameters of the current diagnostic criteria of ARDS/MODS are not suitable in moderately high or high altitude areas. It is necessary to set up the diagnostic criteria of H-ARDS/MODS. (2)Some clinical characteristics might change in areas 1,500 m altitude or higher. The pathophysiological mechanism might be attributable to peculiar biologic reactions due to hypoxia stress reaction, and it is worth further study.

OBJECTIVE: To investigate the expression of urokinase-type plasminogen activator (uPA) and its receptor (uPAR) in squamous cell carcinoma of hypopharynx and reveal the correlation of the major clinicopathological parameters and prognosis. METHOD: Samples of 48 hypopharyngeal carcinoma and 10 normal hypopharyngeal tissue were detected by immunohistochemistry method (SP method) for urokinase-type plasminogen activator (uPA) and its receptor (uPAR). The correlation between the expression of urokinase-type plasminogen activator and its receptor and the major clinicopathological parameters of hypopharyngeal carcinoma were analyzed by rank sum test and Spearman correlation analysis. Overall survival were analyzed according to Kaplan-Meier and log-rank statistics, the prognostic relevance of uPA and uPAR and conventional prognostic factors were analyzed by Cox analysis. RESULT: In 48 hypopharyngeal carcinoma specimens, positive expression rates of uPA and uPAR were 77.1% and 68.75% respectively, which were significantly higher than in normal tissues (P < 0.01). The uPA and uPAR positive expression was correlated with pathological grading, lymph node metastases and growth mode of hypopharyngeal carcinoma. The positive expression rate for uPA and uPAR in patients with lower pathological grading, lymph node metastases and invasion growth mode were significantly higher than in patients with higher pathological grading, non-lymph node metastases and non-invasion growth mode. Patients were followed-up postoperatively. The positive expression of uPA and uPAR were correlated with prognosis (P < 0.05 and P < 0.01). According to Log-rank statistics, patients with positive expression of uPA and uPAR had a significantly shorter survival time than those with negative expression of uPA and uPAR. Multivariate Cox analysis revealed that three independent prognostic factors for overall survival time were clinical stage, invasion growth mode and uPAR expression. CONCLUSION The positive expression of uPA and uPAR in hypopharyngeal carcinoma were significantly higher than in normal tissues. uPAR is a new independent and strong biologically prognostic factors, which positive expression may be a powerful aid in evaluating metastatic potential and High-Risk patients in early stage of hypopharynx carcinoma ryngeal carcinoma.

Background: Intertrochanteric hip fractures are among the most common and most expensive diagnoses in the Medicare population. Liposomal bupivacaine is a novel preparation of a commonly used analgesic agent that, when used intraoperatively, decreases narcotic requirements and hospital length of stay and increases the likelihood of discharge to home. The purpose of this investigation was to determine whether there was an economic benefit to utilizing intraoperative liposomal bupivacaine in patients with fragility intertrochanteric hip fractures in comparison to a group of patients who did not receive liposomal bupivacaine. Methods: This is a retrospective observational study performed at two academic medical centers. Fifty-six patients with intertrochanteric hip fractures treated with cephalomedullary nail implant who received standard hip fracture pain management protocol were compared to a cohort of 46 patients with intertrochanteric hip fractures who received additional intraoperative injections of liposomal bupivacaine. All other standards of care were identical. A cost analysis was completed including the cost of liposomal bupivacaine, operating room costs, and discharge destination. Statistical significance was set at p < 0.05. Results: Although the length of hospital stay was similar between the two groups (3.2 days vs. 3.8 days, p = 0.08), patients receiving intraoperative liposomal bupivacaine had a lower likelihood of discharge to a skilled nursing facility (84.8% vs. 96.4%, p = 0.002) and a longer operative time (73.4 minutes vs 67.2 minutes, p = 0.004). The cost-benefit analysis indicated that for an investment of $334.18 in the administration of 266 mg of liposomal bupivacaine, there was a relative saving of $1,323.21 compared to the control group. The benefit-cost ratio was 3.95, indicating a $3.95 benefit for each $1 spent in liposomal bupivacaine. Conclusions Despite the increased initial cost, intraoperative use of liposomal bupivacaine was found to be a cost-effective intervention due to the higher likelihood of discharge to home during the postoperative management of patients with intertrochanteric hip fractures.

Objective: To analyze the effect of colorectal cancer screening in the general population in Guangzhou, and provide evidence for the for development of colorectal cancer screening policy and strategy. Methods: The data of colorectal cancer screening in Guangzhou during 2015- 2016 were collected. The participation, the positive rate of fecal occult blood test, the detection rate of colonoscopy and screening effect of colonoscopy were evaluated. Results: A total of 220 834 residents aged 50-74 years received the screening, and the positive rate of the screening was 16.77% (37 040 cases). Colonoscopy was performed for 7 821 cases (21.12%). Colorectal lesions were found in 4 126 cases (52.76%), of which 614 (7.85%) and 73 (0.93%) and 230 (2.94%) were identified as advanced adenoma, severe dysplasia lesions and colorectal cancers, respectively. The detection rates of all colorectal lesions were higher in men than in women (all P<0.01). The diagnostic rate of early lesion was 87.24%, and 99 early cancer cases were found, accounting for 46.26% of the total cases. The overall screening detection rate of colorectal cancer was 104.15/100 000, higher than the incidence rate (81.18/100 000) in colorectal cancer surveillance (P<0.001), but age group <70 years had higher detection rate, age group ≥70 years had higher incidence rate. Conclusions: The colorectal cancer screening strategy in Guangzhou is effective in the detection of the population at high risk, increase the detection rate of colorectal lesions, early diagnosis rate of precancerous lesions and diagnosis rate of early colorectal cancer. The benefit in those aged ≤69 years was more obvious than that in those aged 70-74 years. It is necessary to improve the compliancy of colorectal cancer screening in population at high risk.

Objective: To explore the characteristics of distribution on Chinese adult body mass index (BMI) in different age groups and genders and to provide reference related to obesity and related chronic diseases. Methods: Data from the China Health and Nutrition Survey in 2009 were used. Sequential sample cluster method was used to analyze the characteristics of BMI distribution in different age groups and genders by SAS. Results: Our results showed that the adult BMI in China should be divided into 3 groups according to their age, as 20 to 40 years old, 40 to 65 years old, and> 65 years old, in females or in total when grouped by difference of 5 years. For groupings in male, the three groups should be as 20 to 40, 40 to 60 years old and>60 years old. There were differences on distribution between the male and female groups. When grouped by difference of 10 years, all of the clusters for male, female and total groups as 20-40, 40-60 and>60 years old, became similar for the three classes, respectively, with no differences of distribution between gender, suggesting that the 5-years grouping was more accurate than the 10-years one, and BMI showing gender differences. Conclusions: BMI of the Chinese adults should be divided into 3 categories according to the characteristics of their age. Our results showed that BMI was increasing with age in youths and adolescents, remained unchanged in the middle-aged but decreasing in the elderly.

Objective: To investigate the effects of hepatitis B virus (HBV) genotype and mutations on the development of hepatocellular carcinoma (HCC) and to establish a new qualified HCC risk scores. Methods: A cohort study enrolling patients with chronic HBV infection was conducted. HBV genotypes were identified by nested multiplex PCR. HBV mutations in the basic core promoter region and PreS region were sequenced after PCR amplification. Scores on risk factors were set based on nomogram. Results: Totally, 1 525 patients were followed-up in this research. A total of 1 110 patients infected with genotype C were followed-up for 8.52 (Q(R): 5.36-11.68) years on average, of whom the incidence of HCC was 11.93/1 000 person-years. In genotype C HBV infected patients, male gender, aged 40 years and over, and four DNA mutations (T1674CG, A1762T/G1764A, A3120T, and A2962G) can increase the risk of HCC (P<0.05); interferon therapy can reduce the risk of HCC (P<0.05). A new HCC predicting model was established according to the results. After validation, the predicted disease-free survival rate was consistent with the real one. Conclusions: Hepatitis B virus genotypes and mutations were closely associated with HCC. The new risk scoring system can well predict HCC occurrence in genotype C HBV infected patients.
