l014 faecal specimens were collected from 4 hospitals in Nanjing to investigate the infection of Cryptosporidium. Each faecal specimen was smeared and screened by auramine-phenol staining method for oocyst, the positive and suspected specimens were identified by modified acid-fast staining method and safranin-methylene blue staining method. The result showed that 13 spccimens were positive by auramine-phenol staining method and confirmed by modified acid-fast staining method. 5 suspected specimens were negative as shown by the latter two methods.The best result could be obtained when auramine-phenol staining method was first used and folloWed by modified acid-fast staining method. This-technique is simple, sensitive and reliable. It is difficult to find oocysts by safranin methylene blue staining method when the oocysts are few (Figs. l-3).

This study is to report the establishment of an UPLC-MS/MS method for the determination of plasma concentration of UA carried in self-microemulsifying drug delivery system (SMEDDS) and its pharmacokinetics in rats. It was used for determination and analysis when serum with internal standard was extracted from C18 solid-phase column. Acquity UPLC BEH C18 column (100 mm x 2.1 mm, 1.7 microm) was used for separation. The mobile phase was acetonitrile -0.1% ammonia with gradient elution at the flow rate of 0.2 mL x min(-1). The column temperature was 40 degrees C and the detection wave length was 210 nm. It was detected by negative ion using electrospray ionization source (ESI) and scanned by multiple reaction ion monitoring (MRM) mode. The liner relationship of UA was very good in the range of 1.19-3 815.00 ng x mL(-1) (r = 0.999 0). Recovery rate of different concentrations were 87.42%-89.95%. The precision of inter-day and intra-day were less than 11%. The method developed in our study was proved to be sensitive, rapid and simple. It is suitable for the pharmacokinetic study of UA-SMEDDS in rats.

Background:Fibroscan is the noninvasive method widely used to evaluate quantitatively the liver fibrosis and monitor the long-term efficacy of anti-fibrosis therapy. Aims:To study the use of Fibroscan for evaluating the efficacy of combined therapy with FuFang BieJia RuanGan tablet and antiviral drugs in patients with hepatitis B virus( HBV)-related cirrhosis. Methods:A total of 90 patients with HBV-related cirrhosis from March 2013 to September 2014 at Shanghai Ren Ji Hospital were recruited,and divided into treatment group and control group. Patients in treatment group received FuFang BieJia RuanGan tablet,and patients in control group received conventional liver-protective drugs,all the patients took nucleoside antiviral drugs at the same time. The treatment courses in both groups were 6 months. Liver stiffness measurement( LSM)was detected by Fibroscan before and after treatment. Biochemical parameters,width of portal vein and clinical symptoms were recorded. Results:After treatment,LSM was significantly decreased in both groups( P <0.05). Liver function,width of portal vein and Child-Pugh score were improved in both groups(P <0. 05),and no significant differences were found between the two groups(P>0. 05). LSM was closely associated with Child-Pugh score both before and after treatment(r=0. 484,P<0. 01;r=0. 523,P<0. 01). Patients with Child-Pugh A had lower LSM than those with Child-Pugh B or Child-Pugh C(P<0. 01). Conclusions:FuFang BieJia RuanGan tablet combined with oral antiviral drugs can remarkably improve the liver function of cirrhotic patients and prevent progression of cirrhosis. Dynamic detection of LSM can be used for monitoring drug efficacy and disease progression in patients with cirrhosis.

Objective To explore the efficacy of multiple interventional models combined through anterior tibial veins approach in treatment of acute deep venous thrombosis (DVT).Methods The clinical data and the imaging materials of 10 patients with acute DVT were analyzed retrospectively,and the interventional treatment strategies were discussed.Results The percutaneous mechanical thrombectomy (PMT) was performed after a temporary inferior vena cava filter implanted in all patients,and thrombus clearance rate of grade Ⅲ was obtained in 7 patients while 3 patients reached grade Ⅱ criteria.There were 7 patients underwent angioplasty,then the inferior vena cava filter was retrieved during the same procedure in 5 patients while 4 patients in the second stage and 1 patient rejected to retrieve the filter.All swelling limbs alleviated significantly after those procedures.There was no critical complications occured.The total hospital stay ranged from 4 to 7 days,with a mean time of (6.00±0.94) days.All patients were followed up with a mean time of (3.60± 1.84) months (ranged from 1 to 6 months).No thrombus recurrences of the previously affected vessels were reported.Conclusion The multiple interventional models combined via anterior tibial veins for acute DVT is simple,safe and effective,combined with mechanical thrombectomy device can reduce thrombus burden quickly,and combined with angioplasty can consolidate the therapeutic effect,all those methods combined can shorten the overall hospitalization time.
