Objective To investigate the use of cystoscopy in the diagnosis and treatment of glandular cystitis. Methods A total of 38 cases of glandular cystitis was pathologically diagnosed under cystoscopy.The patients were treated by transurethral electric resection.After surgery a chemotherapy with mitomycin-c bladder irrigation was given once weekly for 8 times and then once monthly for 10 times.During the follow-up a cystoscopy was periodically performed and biopsy samples were pathologically examined with all the cases.Results The follow-up checkups were made for 6~12 months in 38 cases.Of the 38 cases,29 cases were cured(with transitional cell surface covering the bladder musoca gradually),5 were symptomatically relieved,and 4 were found relapsed. Conclusions Cystoscopy can offer valuable help for the diagnosis of glandular cystitis.Treatments with transurethral electric resection and mitomycin-c bladder irrigation are effective for glandular cystitis.

OBJECTIVE To investigate species and drug resistance of pathogenic fungi from patients with urogenital candidiasis.METHODS The fungi were cultured with general method,isolated and identified with CHRO-Magar medium and API20C AUX stripes.Drug sensitive test was tested by M-27-A broth microdilution method recommendated.RESULTS In 331 pathogenic fungi,C.albicans was the most frequent species,followed by C.glabrata and C.parapsilosis.The resistant rate in the female patients was:to itraconazole 3.24%,fluconazole 4.32%,nystatin 4.86%, amphotericin B 6.49%,miconazole 16.76%,ketoconazole 17.84%,and to econazole 28.6%,and that in the male patients was:to nystatin 4.11%,itraconazole 5.48%,fluconazole 8.22%,amphotericin B 10.27%,ketoconazole 17.81%,econazole 23.29% and to miconazole 26.71%.CONCLUSIONS In order to guide clinically the selection of reasonable antifungals,species identification and sensitive test should also be stressed.

Nanopore single molecule sequencing(SMS) is considered as one of the most promising third generation DNA sequencing method by virtue of fast sequencing and low cost. As the most significant part of the sequencing system, the synthetic solid nanopore has recently been the research highlight in the field of nanopore DNA sequencing because of its fine-controlled size, high reliability and wide applicability. Also, its fabrication method is currently one of the main challenges in this field. In this article, the principles of the nanopore SMS are introduced followed by the review of the difficulties and challenges in the current research stage with emphasis on the nanopore fabrication methods.

Objective To design LCD system based on MSP430 using LCD controller S1D13700. Methods MSP430's control bus adopted the communication mode of MSC-51 singlechips, and was connected with S1D13700 by 8-bit data bus. The address buses were linked by the modes of indirect address and direct address respectively. Results The design was used for displaying cardiac wave and its parameters in cardiac monitor successfully. Conclusion The S1D13700's driver program, accomplished with standard ANSI-C, is gifted with brilliant versatility, and thus can be used in the design of the portable device.

Objective To investigate the clinical value of the duodenum double lumen cannula suction in duodenal rupture repair.Methods According to the operation methods,60 patients with duodenal rupture undergoing duodenal repair were divided into the surgical drainage alone group(26 cases)and double sets attract tube group (34 cases).The surgery effect and complications were observed.Results The difference of traffic flow 7 days after the operation between the two groups was statistically significant(t =7.564,P <0.05).The length of stay and hospital costs of the surgical drainage alone group were more than those of the double sets attract tube group,the differences were statistically significant(t =3.567,4.123,all P <0.05).The fistula,intra -abdominal infections,wound infec-tions,pulmonary infection rates of the surgical drainage alone group were 30.77%,42.31%,46.15%,26.92%, which were higher than 2.94%,11.76%,8.82%,2.94%,5.88% of the double sets attract tube group,the differ-ences were statistically significant(χ2 =8.949,7.330,10.950,2.986,5.116,all P <0.05).Conclusion Applica-tion of the double lumen cannula duodenal suction in duodenal rupture repair can significantly reduce the incidence of postoperative complications,has certain security,it is recommended in clinical practice.

Objective To use evidence-based nursing on patients with artificial airway to the practice of stomach tube, and to evaluate the self made guidance for difficult gastric tube placement in patients with artificial airway.Methods Forty patients with artificial airway and were difficult to put the tube, and admitted to Department of Critical Care Medicine of Harrison International Peace Hospital Affiliated to Hebei Medical University from April to December in 2016 were enrolled as observation group. Through the evidence-based nursing strategy, the related literatures at home and abroad were collected to search clinical evidence and formulate and implement the nursing program, the gastric tube was inserted into the stomach tube under the direct vision of the laryngoscope. Thirty-six patients of difficult gastric tube placement with artificial airway straightly under the direct vision of the laryngoscope from August 2015 to March 2016 were retrospectively analyzed as the control group. The success rate of first catheterization, indwelling time, throat edema and bleeding of pharyngeal mucosa were compared between the two groups.Results All patients were enrolled in the final analysis. In the control group, 28 patients were successfully placed once, while 8 failed. Only 1 patient in observation group failed to catheterize, and successful placed after symptomatic treatment, the one-time success rate of catheter was significantly higher than that of control group (97.5% vs. 77.8%), and catheter time was significantly shortened (minutes: 4.8±1.2 vs. 5.1±1.0), the difference was statistically significant (bothP < 0.05). There were 2 patients with laryngeal edema in the control group and 4 patients of pharyngeal mucosal hemorrhage. In the observation group, there was no laryngealedema and laryngeal edema occurred in the patients with laryngoscopy, and only 1 patient had a hemorrhage of pharyngeal mucosa.Conclusion Using self made guiding device can effectively insert the difficult gastric tube in patients with artificial airway, and increase the one-time success rate of intubation, shorten the catheter time, and have a trend in reduce complication as compared with traditional gastric tube placement.

Objective:To evaluate the application of analyzing neutrophil cell surface marker CD64 in diagnosis of premature infants infection.Methods:109 infants inpatient in neonatal department(including NICU)were enrolled in the study.CD64 was measured by FCM,which was compared with C-reactive protein(CRP)and IL-6.Results:There was a statistically significant difference in quantitation of CD64 on neutrophil cells(P

The training of basic scientific research skills is very important for seven-year medical program students.

In the item bank construction of medical microbiology examination questions,the accurate difficulty coefficient is an important parameter to guarantee the quality of the bank.Thus,the accurate difficulty estimate plays an important role in the item bank construction of examination questions.Methods of estimating the difficulty of medical microbiology test questions were explored,based on the knowledge points,the type of test questions,the structure of test questions and the degree of students’ familiarity with the questions and so on.Finally,the feasibility of methods was confirmed through the simulated tests.

This study was aimed to optimize the hydrolysis conditions of Coix prolamin, which occupied the highest content in total protein of it, and then evaluate the angiotensin-converting enzyme (ACE) inhibitory activity of the corresponding hydrolysates. Pepsin was used to hydrolyze prolamin and OPA method was applied to determine the degree of hydrolysis. The optimum conditions of hydrolyzing prolamin were obtained by orthogonal design subse-quently. The ACE inhibitory activity of small molecular weight (less than 3 kD) peptides gained by ultrafiltration of the hydrolysates was assayed by RP-HPLC method. The result showed that the optimized hydrolysis conditions were substrate concentration of 1%, enzyme-to-substrate ratio of 1:5 and hydrolysis duration for 48 h. The hydrolysates exhibited an ACE inhibitory ratio of (83.40 ± 0.93)% at the concentration of 0.1 mg·mL-1. It was concluded that prolamin hydrolysates displayed a high ACE inhibitory activity in vitro, which provided guidance for further research of antihypertensive component and development of functional food from Coix.
