Objective To understand the effect of circumcision in reducing high-risk human papilloma virus (HPV) infection in male adults. Methods One hundred and twenty-eight married adults with phimosis who underwent circumcision enrolled in the case group and high-risk HPV of urethral discharge specimens were detected before and 2 years after operation. A total of 128 cases of phimosis without circumcision were recruited in the control group. High-risk HPV infection rates were compared between the two groups. Results The highrisk HPV infection rates in the two groups were comparable at baseline. In the circumcision group, high-risk HPV infection rate was 27. 3% preoperative and it significantly decreased to 12.5% two years after operation( x2 =8. 839 ,P =0. 005). In the control group,high risk HPV infection rate was 28. 1% at baseline and it was 25.0%two years later, with no significant difference (x2 =0.320,P = 0.671).Conclusion Circumcision can significantly reduce high-risk HPV infection. Promoting circumcision actively in our country may have an important role in preventing high-risk HPV infection.

Varicoceles are vascular lesions of pampiniform plexus and are the most common cause of male infertility. Although ultrasound is the most common way used to diagnose varicocele,there remains much controversy regarding their diagnosis and management,such as the ultrasonic diagnostic criteria and the classification of varicocele,the clinical value of ultrasound in observing the testicular volume with varicocele,whether the information derived from ultrasound is useful to help the clinicians provide intervention timely and appropriately.The literatures are reviewed in an effort to explore the pertinent controversies.

OBJECTIVETo study the phenotypic and genotypic resistance to Fluoroquinolones in Neisseria gonorrhoeae (NG) isolated in Jiangsu province of China.

METHODSIn-vitro, susceptibility testing of ciprofloxacin and levofloxacin against ninety-five clinical isolates were determined by agar dilution method. Detection of mutation in the gyrA and parC genes was performed by polymerase chain reaction (PCR) assay and sequence analysis.

RESULTSThe clinical isolates demonstrated 100% resistance to ciprofloxacin. Based on gyrA and parC mutations, 18 types could be categorized among the 54 isolates. Based on the same gyrA mutations,isolates with high MIC appeared to have had more mutations in parC gene.

CONCLUSIONThe status of resistance to ciprofloxacin in NG was quite serious, and ciprofloxacin treatment for the treatment of NG infections in Jiangsu province should not be recommended. The results from this study suggested that mutations in the parC gene had contributed to the development of high Fluoroquinolone resistance in NG.

Our work focuses on the quality control and structural identification of Photocyanine as a cancer therapeutic photosensitizer. Photocyanine is a mixture which contains four ZnPcS2P2 type substituted Phthalocyanine isomers. In order to obtain the single component from Photocyanine, the mixture of four isomers possessing the similar structures and chemical property had been isolated and purified. An HPLC method with a mixture of methanol-acetonitrile-ion-pair buffer as the mobile phase was applied to isolate the four isomers by means of a semi-preparative C18 column. To remove the salts which were mixed in the preparative product, a SPE C18 column was used to separate the salts by elution with water and then the marker component was eluted by methanol. Subsequently, a column of Sephadex LH-20 gel was applied to elute the crudes with methanol to desalination. The purity of the isolated compound was measured by TLC and four different isomers of phthalocyanine were obtained. The chemical structures of them were elucidated by 1H NMR spectra, gCOSY and NOE1D. An HPLC-DAD method was developed for simultaneously determination of four major isomers in Photocyanine with a C18 column (Grace Smart, 150 mm x 4.6 mm ID, 5 microm). The separation was carried out with a gradient program at a flow rate of 1.0 mL x min(-1). The mobile phase was a mixture of acetonitrile and ion-pair buffer (0.01 mol x L(-1) hexadecyl trimethyl ammonium bromide and 0.01 mol x L(-1) potassium dihydrogen phosphate, adjusted the pH value to 6.8 with potassium hydroxide solution). The resolution values of four isomers were 2.5, 1.20, 1.33, and 1.8. Linear regression analysis for four compounds was performed by the external standard method. Four constituents were linear in the concentration range of 0.005 to 10 microg. The values of relative standard deviation (RSD) of intra-day were 0.12%, 0.66%, 0.99%, and 1.21%, respectively. The limits of detection for four compounds were 15 ng, 20 ng, 12 ng, and 25 ng, respectively. This method was simple, accurate and reproducible. The developed method can be successfully applied to analyze isomers in Photocyanine.

BACKGROUND/AIMS: To evaluate the enhancement patterns of liver metastases and their influencing factors using dynamic contrast-enhanced ultrasound (CEUS). METHODS: A total of 240 patients (139 male and 101 female; 58.5±11.2 years of age) diagnosed with liver metastases in our hospital were enrolled in this study to evaluate tumor characteristics using CEUS. A comparison of enhancement patterns with tumor size and primary tumor type was performed using the chi-square test. The differences between quantitative variables were evaluated with the independent-sample t-test and one-way analysis of variance. RESULTS: The enhancement patterns of liver metastases on CEUS were categorized as diffuse homogeneous hyperenhancement (133/240, 55.4%), rim-like hyperenhancement (80/240, 33.3%), heterogeneous hyperenhancement (10/240, 4.2%), and isoenhancement (17/240, 7.1%). There were significant differences in the enhancement patterns during the arterial phase based on the nodule size (p=0.001). A total of 231 of the nodules showed complete washout during the portal phase, and 237 nodules were hypoenhanced during the delayed phase. The washout time was correlated with tumor vascularity, with a longer washout time observed in hypervascular metastases compared to hypovascular metastases (p=0.033). CONCLUSIONS: Diffuse homogeneous hyperenhancement followed by rapid washout was the most common enhancement pattern of liver metastases on CEUS and was affected by the nodule size and tumor vascularity. Small metastases were prone to show diffuse homogeneous hyperenhancement. Hyper-vascular metastases showed a significantly longer washout time compared to hypovascular metastases.

Objective To explore the impact of diagnosis related groups (DRGs) payment and drug zero plus on the management of intensive care medicine department. Methods The clinical data of patients in one year from 2016 to 2017 admitted into the Department of ICU in Liuzhou Worker's Hospital concerning their numbers of discharged patients, transferred patients, bed utilization rate, number of bed turnover, average length of stay of discharged patients, cure and improvement rates, admission and discharge diagnostic coincidence rate, 3-day definite diagnosis rate, clinicopathological diagnosis coincidence rate, rescue success rate, total income, drug proportion, consumable proportion, DRGs payment and settlement data, etc were retrospectively analyzed to explore the dual challenges, DRGs payment and drug zero plus, facing the department and how to respond and deal with them. Results In 2016 and 2017, the total incomes of the department of critical care medicine in our hospital were 42.107 0 million yuan and 41.371 3 million yuan respectively, and the medical insurance incomes were 15.03 million yuan and 16.69 million yuan respectively;in 2016 and 2017, 2 693 patients and 2 922 patients were admitted and treated respectively; 595 patients and 577 patients were discharged respectively, with 2 071 patients and 2 334 patients transferred respectively; the balances of the department were 15.48 million yuan and 29.11 million yuan, respectively. From July to December 2017, the medical insurance DRGs payment data suggested that the proportion of loss of the department be 7.02%. Accelerating the Grade 6 electronic medical records and informationization construction, adopting the severe disease information solution program and fine quality control management in the department of critical care medicine can reduce the cost of manpower. Conclusion Our future development direction in the Department of Intensive Care Medicine includes the following aspects: Open source and reduce expenditure, strictly control the proportions of drugs and consumables, improve the balance of the department, and actively respond and deal with the medical insurance DRGs payment.

OBJECTIVE: To evaluate the value of enhancement features and quantitative parameters of contrast-enhanced ultrasonography (CEUS) in differentiating solid hypoechoic renal angiomyolipomas (AMLs) from clear cell renal cell carcinomas (ccRCCs). MATERIALS AND METHODS: We analyzed the enhancement features and quantitative parameters of CEUS in 174 hypoechoic renal masses (32 AMLs and 142 ccRCCs) included in the study. RESULTS: Centripetal enhancement pattern was more common in AMLs than in ccRCCs on CEUS (71.9% vs. 23.2%, p < 0.001). At peak enhancement, all AMLs showed homogeneous enhancement (100% in AML, 27.5% in ccRCCs; p < 0.001). Quantitative analysis showed no significant difference between rise time and time to peak. Tumor-to-cortex (TOC) enhancement ratio in AMLs was significantly lower than that in ccRCCs (p < 0.001). The criteria of centripetal enhancement and homogeneous peak enhancement together with TOC ratio < 91.0% used to differentiate hypoechoic AMLs from ccRCCs resulted in a sensitivity and specificity of 68.9% and 95.8%, respectively. CONCLUSION: Both qualitative and quantitative analysis with CEUS are valuable in the differential diagnosis of hypoechoic renal AMLs from ccRCCs.

OBJECTIVETo study zedoary turmeric oil (ZTO) and the pharmacokinetics of its homemade compound antiviral preparation in New Zealand rabbits.

METHODRP-HPLC was used to determinate the content of germacrone in rabbit plasma after oral administration.

RESULTAfter oral administration of ZTO and its homemade compound antiviral preparation, the plasma concentration-time curve of germacrone is in conformity to two-compartment open model. The pharmacokinetic parameters of ZTO: t1/2alpha, t1/2beta, Vd, CL, AUC and Ka were (1.52 +/- 0.59), (1.97 +/- 0.27) h, (47.59 +/- 2.29) L x kg(-1), (176.77 +/- 7.65) L x h(-1) x kg(-1), (5.70 +/- 0.70) mg x h x L(-1) and (0.97 +/- 0.11) h(-1), respectively, while those of compound preparation were (0.41 +/- 0.03), (1.47 +/- 0.35) h, (75.21 +/- 5.21) L x kg(-1), (287.79 +/- 6.39) L x h(-1) x kg(-1), (3.91 +/- 0.53) mg x h x L(-1) and (5.14 +/- 1.26) h(-1), respectively. There was no significant difference between the above two groups of pharmacokinetic parameters, expect that Ka of compound preparation was significantly higher than that of ZTO (P < 0.05).

CONCLUSIONHypericum perforatum in compound preparation doesn't impact the distribution and elimination of active ingredients of ZTO in New Zealand rabbits, but it improves the absorption speed, and shortens the time of drug absorption, which contributes to rapid efficacy of ZTO in rabbits.
