Objective To evaluate the efficacy and safety of ureteroscopic endo-incision and drainage in the treatment of renal cysts.Methods Thirty cases(19 females and 11 males)of renal cysts(1 1 parapelvie cysts,15 simple cysts.and 4 multiple cysts)were treated with ureteroscopic endo-incision and drainage.The renal cysts were located in renal pelvis,and opened and decompressed by electrotme with ureteroscope.Double J stent was placed afterwards.Urinary and blood biochemistry were tested post-operatively.Results All the operations were successfully completed with no severe complication.The cyst managing time ranged from 15 tO 45 min.Urinary biochemistry(urinary protein and glucose)turned normal 1 2 days after the surgery.Patients were followed up for 3 to 9 months.Renal cysts disappeared in 24 cases,diminished in 4 cases,and recurred in 2 cases.Conclusion Application of ureteroscopic technique in the treatment of renal cyst is safe,effective and minimally invasive.

?AIM: To explore the relation of homocysteine ( Hcy ) and its metabolic related indicators with primary angle-closure glaucoma ( PACG) .?METHODS: In this study, a total of 150 PACG patients and 150 controls were enrolled. The patients with PACG were diagnosed by applanation tonometer, Humphrey perimetry ( HVF ) , optical coherence tomography ( OCT ) , gonioscope. The normal controls were recruited from physical examination center. Blood samples were collected and the plasma was used to determine homocysteine, vitamin B12 and folic acid. DNA was extracted to determine the methylenetetrahydrofolate reductase ( MTHFR ) C677TT genotype and gene polymorphism.?RESULTS:There was a statistically significant difference (t=2. 04,P=0. 04) in mean homocysteine levels between patients with PACG ( 16. 11 ± 1. 66μmol/L ) and controls (15. 74± 1. 52μmol/L). The level of vitamin B12 in PACG group was 248. 09 ± 119. 07pg/mL and the control group was 230. 21 ± 142. 93pg/mL. No statistically significant difference was found on the vitamin B12 level between the two groups ( t = 0. 84, P = 0. 40 ). The folic acid levels showed no statistically significant differences( t=1. 65,P=0.17) between the PACG group(12. 02±7. 81ng/mL) and the control group (13. 15 ± 6. 25ng/mL). The frequency distribution of the MTHFR C677T genotypes was found to be significantly associated (χ2 =6. 2,P<0. 05) with PCAG (CC 84. 7%, CT 4. 7%, TT 10. 7%) as compared to the controls (CC 94. 7%, CT 2. 0%, TT 3. 3%). The frequency distribution of TT genotypes of MTHFR C677T in the PACG group was significantly higher than that in the control group. Moreover, our findings showed significant difference (χ2=14. 2,P<0. 05) between the allele frequency of the C677T single nucleotide polymorphism within the MTHFR gene in POAG patients ( T 87. 0%, C 13. 0%) and the control group(T 95. 7%,C 4. 3%) .?CONCLUSION: These results show that the Hcy level and the TT genotypes of MTHFR C677T were higher in the PACG patients than in controls. Therefore, our data suggests that high Hcy level and the related indicators are associated with high PACG risk.

Objective To explore the clinical and pathologic characteristic of deep fungus infection under mechanical ventilation in neonate. Method The clinical datas of 18 neonates under mechanical ventilation approved with deep fungus infection by autopsy from 1985 to 2003 in our department were collected and analyzed.Results In 18 infants who survived deep fungus infection,2 cases were premature and 16 cases were mature,the birth weight and the numbers of patients were:2500 g 2 cases;Time under mechanical ventilation was 8-86 days and the average time under mechanical ventilation was 13 days. The pathogen caused deep fungus infection was Aspergillus(8/18),Candida albicans(6/18) and Mucor(4/18),respectively. The infected organ were lung(12/18),brain(2/18),liver(4/18) and gastrointestinal tract(2/18),respectively.Two of them were found been infected in lung and liver at the same time.Conclusions We must attach importance to deep fungus infection in neonate under machine ventilation.Aspergillus and Candida albicans were the main pathogen bacteria and lung was the main infected organ of neonatal deep fungus infection.Early diagnosis may be the efficiency approach to increase livability.

BACKGROUND/AIMS: Healthcare-associated infections (HAIs) in critically ill patients with prolonged length of hospital stay and increased medical costs. The aim of this study is to assess whether daily chlorhexidine gluconate (CHG) bathing will significantly reduce the rates of HAIs in adult intensive care units (ICUs). METHODS: PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials were systematically searched until December 31, 2014 to identify relevant studies. Two authors independently reviewed and extracted data from included studies. All data was analyzed by Review Manager version 5.3. RESULTS: Fifteen studies including three randomized controlled trials and 12 quasi-experimental studies were available in this study. The outcomes showed that daily CHG bathing were associated with significant reduction in the rates of primary outcomes: catheter-related bloodstream infection (risk ratio [RR], 0.44; 95% confidence interval [CI], 0.32 to 0.63; p < 0.00001), catheter-associated urinary tract infection (RR, 0.68; 95% CI, 0.52 to 0.88; p = 0.004), ventilator-associated pneumonia (RR, 0.73; 95% CI, 0.57 to 0.93; p = 0.01), acquisition of methicillin-resistant Staphylococcus aureus (RR, 0.78; 95% CI, 0.68 to 0.91; p = 0.001) and vancomycin-resistant Enterococcus (RR, 0.56; 95% CI, 0.31 to 0.99; p = 0.05). CONCLUSIONS: Our study suggests that the use of daily CHG bathing can significantly prevent HAIs in ICUs. However, more well-designed studies are needed to confirm these findings.

OBJECTIVETo develop a new method for determination of Mangiferin in the leafs of Folium mangiferae. By this new method, Mangiferin in F. mangiferae sampled in different months and in different regions was determinated.

METHODA RP-HPLC method was set up, using Shim pack CLC-ODS column, methanol-0.05 mol.L-1 H3PO4(65:134, pH 3.5) as mobile phase, with 258 nm of detection wave, at room temperature, 1 mL.min-1. F. mangiferae sampled in Nanning, Qinzhou and Tianyang, Guangxi province and sampled respectively in January to December were determinated.

RESULTThe average recovery of the RP-HPLC was 99.2%, RSD = 1.05% (n = 5). The content of Mangiferin in F. mangiferae was statistically different due to different sample-regions or sample-time.

CONCLUSIONThis RP-HPLC method is simple, specific and exact. The contents of Mangiferin in the leafs of F. mangiferae sample in Nanning and Tinayang were statistically similar, but higher than that in Qinzhou. The contents of Mangiferin in the leafs of F. mangiferae sampled in July to October were higher than that in the other months. The content in September was the highest, the content in February was the lowest.

OBJECTIVETo investigate the dynamic changes of the epididymal size 1 year after vasectomy.

METHODSFifty male volunteers received vasoligation. Before and at 1, 2, 3, 6, and 12 months after operation, we measured the size and detected the internal echoes of the epididymis using color Doppler ultrasonography.

RESULTSThe bilateral epididymides were both thickened post-operatively in all the 50 cases, with statistically significant differences between the baseline and the 1st month, the 1st and the 2nd month, the 2nd and the 3rd month, or the 3rd and the 6th month after surgery (all P < 0.01), but not between the 6th and the 12th month (P > 0.05).

CONCLUSIONWithin 6 months after vasectomy, the bilateral epididymides manifested a progressive thickening, but basically restored their balance of secretion-absorption after 6 months.

OBJECTIVETo evaluate the clinical efficacy of mini-open repair for the treatment of acute closed achilles tendon ruptures.

METHODSFrom April 2012 and October 2013,14 patients (14 feet) with acute closed achilles tendon ruptures were treated in our department. They were 9 males and 5 females, with an average age of 30.5 years old (ranged, 25 to 49 years old). The interval between injury and operation ranged from 1 to 13 days (8 days on average). A longitudinal incision approximately 1.5 to 2.0 cm in length was made around the ruptured achilles tendon for mini-open repair after insertion of oval clamp. Postoperative rehabilitation was carried out.

RESULTSThe wounds healed at the first stage except 2 cases with slow recovery. All the patients were followed up for 6 to 24 months, with an average of 11 months. According to the ankle-hindfoot scoring system of American Orthopaedic Foot & Ankle Society (AOFAS),the score was 92.71 ± 6.58 (82 to 100).

CONCLUSIONThe surgical treatment of acute achilles tendon rupture with mini-open repair has advantages of little invasion, a low rate of incision problems, quick function recovery, and simple operation, and it is suitable for primary hospital.

In this work, a rapid analysis method basing on ultraviolet spectroscopy was established for the determination of danshensu, protocatechuic aldehyde, rosmarinci acid, lithospermic acid and salvianolic acid B in the extraction process of Danhong injection. In the extraction process of Danshen and Honghua crude drugs, 44 extraction solution samples were collected and the contents of the five components were determined by HPLC analysis. The ultraviolet spectra of the samples were collected. Partial least square regression was used to establish the multivariate calibration models between the ultraviolet spectra and the contents of the five components. The results showed that the established models could predict the contents of the five components in the extraction solution accurately. The ultraviolet spectroscopy method established in this work can be used for rapid analysis of the intermediates of Danhong injection, which may be applied for the quality control in the manufacturing process.

OBJECTIVETo identify the effective stress management strategies among the Chinese.

METHODSThe sample was selected from Hangzhou, Guangzhou, Chongqing and Taiyuan by using a multi-stage sampling procedure, including 3679 subjects. The data were collected using the household interviewing survey method. The Chinese perceived stress scales (CPSS) measured stress. Stress management strategies included the cognitive and behavioral ones, the former were further divided into positive, neutral and negative ones and the latter were divided into three kinds, i.e. looking for support, liberating and displacing, and relaxing and detracting. The frequency of their usage and their perceived effectiveness were assessed. Multivariable analysis was used to examine the association between various stress management strategies and stress.

RESULTSThe prevalence of health risk stress (HRS) was 44.54% (95% CI: 42.90% - 46.12%). Among the cognitive strategies, all the positive strategies and one of neutral strategies ("Suiyuan") were associated with lower HRS, and the rest of them had no effects. Among the behavioral strategies, all were associated with lower HRS except that of looking for support.

CONCLUSIONThe effective stress management strategies identified in this study might be used to develop a stress management program.
