OBJECTIVE To understand nosocomial candidal infection among tuberculosis patients and its drug(sensitivity).(METHODS) Totally 6280 clinical samples from Jan 2002 to Dec 2004 were cultured;and part of(positive) ones were tested their drug sensitivity to FC,FLC,KET and ITC.RESULTS From all cultured samples 2767 Candida strains(positive rate was 44.06%) were isolated.From them C.albicans,C.glabrata,C.tropicalis,C.krusei and other Candida were 2006, 344,206,95 and 116 strains,their positive rate was 31.94%,(5.48%),3.28%, 1.51% and 1.85%,respectively.Their drug sensitivity rate to four drugs were as follows: to FC was 93.73%,to TTC 62.76%,to FLC 51.03% and to KET was 47.59%. CONCLUSIONS The condition of(tuberculosis) patient would become serious due to higher dual infection rate by Candida after too long anti-(tuberculosis) treatment.Among the four kinds of drugs the FC has the best anti-candidal activity.

Aim To investigate how Farnesoid X re-ceptor (FXR),a nuclear hormone receptor,acts on neurological behaviors such as emotion,social behav-ior,memory and so on.Methods FXR’s function in central nervous system was evaluated by conducting a battery of behavioral tests including elevated plus maze test (EPMT),forced-swimming test (FST),social in-teraction test (SIT ), and passive avoidance test (PAT),and the contents of neurotransmitters were de-termined by the LC-MS /MS method in FXR knockout (KO)female mice and their wild-type controls.Re-sults FXR KO mice showed significantly increased immobility time in FST (P <0.01 ),and it showed in-creased tendency to enter the open arms in EMPT (P<0.01 ).The number of probing the open arms by FXR KO mice was more than that of the controls.Mo-reover,in SIT,FXR KO mice had remarkably in-creased sniffing interactions with the stranger mouse in the same cage (P <0.01 ).But in PAT,the latency for FXR KO mice to enter the dark chamber on the test day and the number of FXR KO mice to enter the dark chamber didn’t differ from those wild-type mice.In hippocampus,the contents of GABA,Glu,and NE were decreased prominently in FXR KO mice (P <0.05,P <0.05 and P <0.01 ,respectively)as well as the ratio of GABA to Glu (P <0.05).But in pre-frontal cortex,none of the neurotransmitters examined showed any difference between FXR KO mice and their controls.Conclusion FXR may be involved in main-tenance of the homeostasis of neural transmission in the central nervous system,thereby influences the emotion-al and social behavior in animals.

Hepatic encephalopathy (HE) is a common and complex neuropsychiatric complication in patients with liver cirrhosis and has the features of high incidence, recurrence, and mortality rates, and it is also an important factor for the increased risk of hospitalization and rehospitalization. At present, there are still no effective drugs for HE. Recent studies have found that intestinal microecological changes are associated with the development, progression, and prognosis of HE, and the regulation of intestinal flora has a certain preventive effect on HE. This article summarizes the research on the association between intestinal microecology and HE in recent years and hopes to provide new ideas for clinical prevention and treatment of HE.

Objective: To investigate the peak time and peak area of elements in cadmium telluride quantum dots (CdTe QDs) using size exclusion chromatography-high-performance liquid chromatography-inductively coupled plasma mass spectrometry, as well as the biological stability of CdTe QDs in vivo and in vitro. Methods: Transmission electron microscope and ultraviolet fluorescence were used for characterization and synthesis of water-soluble CdTe QDs, and CdTe QDs were added to double-distilled water, mobile phase, or bovine serum medium to observe the change in stability after different periods of time. CdTe QDs were injected into the vein of mice, and the changes in the morphology of CdTe QDs in serum and the liver were measured at 1, 24, and 72 hours after exposure. Size exclusion chromatography-high-performance liquid chromatography was used for the elution of the compounds in the solution based on their volume, and then inductively coupled plasma mass spectrometry was performed for the eluent. The flow time of ¹¹⁴Cd and ¹³⁰Te and molar ratio were used for qualitative analysis of CdTe QDs, and the peak area was used to judge whether CdTe QDs were degraded. Results: CdTe QDs were diluted to a concentration of 0.5 mmol/L with double-distilled water and then placed in a dark place at room temperature; CdTe QDs were completely degraded after 60 minutes. CdTe QDs were diluted to a concentration of 0.005 mmol/L with a mobile phase, and the peak of CdTe QDs was not detected. After CdTe QDs were placed in a dark place at room temperature for 48 hours at a concentration of 0.005 mmol/L in bovine serum mediumin vitro, the peak area of ¹¹⁴Cd was 6179841-7346084, and the peak area of ¹³⁰Te was 1077913-1191066. CdTe QDs had the highest peak area at 1 hour after exposure, and the peak areas of ¹¹⁴Cd and ¹³⁰Te were 18183894 and 25187987, respectively. CdTe QDs were quickly degraded in the liver; at 1 hour after exposure, the degradation products of CdTe QDs containing Cd were observed in liver tissue homogenate, and CdTe QDs were largely degradedat 24 hours. Conclusion This method can be used to investigate the biological stability of CdTe QDs. CdTe QDs are degraded in the liver and produce Cd²⁺, which may cause toxic reaction.

Objective To investigate the recurrence and survival of postoperative patients with differentiated thyroid carcinoma (DTC) aged from 25 to 59 years.Methods We retrospectively analyzed the clinical data of 36 patients with DTC treated in our hospital from 1996 to 2011,and the recurrence and survival status of the patients were recorded.Kaplan-Meier analysis was carried out to analyze factors that affect the patient's survival.Results Nine patients died of recurrence or metastasis,and the interval between the initial surgery and recurrence ranged from 22 to 46 months.The survival time of the 36 patients ranged from 34 to 135 months with a 10-year survival rate of 75.0％.Kaplan-Meier analysis showed that male patients had a significantly shorter mean survival time than female patients (χ2＝3.164,P=0.041);the median survival time of patients aged 45-59 years was obviously shorter than that of patients aged 25-44 years (χ2＝4.622,P=0.032);the postoperative survival in patients with 131I therapy was significantly longer than those who did not receive the therapy (χ2＝4.527,P=0.033),and was not affected by total excision of the thyroid gland (χ2=0.988,P＝0.320).No significant difference was found in the median survival of patients in different clinical stages (χ2=2.2132,P=0.167).Conclusion In young and middle-aged patients with DTC,postoperative recurrence is the most likely in 2 to 4 years after the surgery.Male patients at 45-59 years of age who do not receive 131I treatment are at high risks of tumor recurrence.

Objective To investigate the application of continuing care in the indwelling gastric tube feeding of patients with dysphagia in order to improve the patients′ satisfaction and reduce complication as well as the readmission rate. Methods A total of 60 discharged patients undergoing indwelling gastric tube feeding were selected as the study subjects. Out-of-hospital nursing team conducted active care in the observation group consisting of 30 patients while the control group with 30 patients went back home and received passive care from the out-of-hospital nursing team. Indexes of the two groups were collected including complications after two-month indwelling gastric tube feeding, patients′ satisfaction, re-attendance rate, active consultation rate and swallowing rehabilitation and so on.

Objective:To investigate the effect of anti-liver fibrosis treatment on the occurrence of liver cancer in patients with hepatitis B-related liver cirrhosis within three years.Methods:1,049 cases with hepatitis B-related liver cirrhosis who were hospitalized in Beijing Ditan Hospital affiliated to Capital Medical University from October 2008 to August 2016 were enrolled. Clinical data were collected, and COX regression analysis was used to find the independent influencing factors for the occurrence of liver cancer in patients with hepatitis B-related liver cirrhosis within three years. According to whether the patients had received anti-liver fibrosis treatment for ≥ 6 months, they were divided into combination and antiviral group. There were 388 cases in combination group and 661 cases in antiviral group. In addition, the combination group received anti-liver fibrosis therapy with Chinese patent medicine on the basis of antivirus, and the antiviral group received antiviral treatment. The incidence of liver cancer within three years were compared between the two groups, and the incidence of liver cancer in patients with different Child-Pugh grades and mPAGE-B risks was further analyzed. The independent samples t-test, Mann Whitney U test, χ2 test or Fisher's exact probability method were used for data comparison.Results:Anti-liver fibrosis treatment was an independent protective factor to prevent liver cancer in patients with hepatitis B-related liver cirrhosis within 3 years ( P < 0.05). The incidence of liver cancer in the combination group was lower than antiviral group within 3 years (10.3% vs. 15.4%, χ2 = 5.480, P < 0.05). Child-Pugh stratified analysis showed that the risk of liver cancer was significantly reduced in Child-Pugh grade A patients (6.7% vs. 12.6%, χ2 = 2.857, P = 0.040). Among high-risk patients with mPAGE-B, the incidence of liver cancer was significantly lower in combination group than control group (13.7% vs. 19.9%, χ2 = 6.671, P = 0.031). Conclusion:Compared to antiviral therapy alone, combined anti-liver fibrosis and antiviral therapy can reduce the liver cancer occurrence risk in patients with hepatitis B-related liver cirrhosis for 3 years. Patients with Child-Pugh grade A and high-risk group by mPAGE-B scores are the dominant population to receive treatment.
