To observe local inflammation reaction and vein thrombosis on rabbit ear vein with methotrexate , ceftri-axone sodium and normal saline .With the extension use of drugs , the numbers of inflammation reaction and throm-bosis in each group were increased , and antibiotic and chemotherapy drug group had a higher rate than the normal saline group .There was a statistically significant difference of the inflammation reaction between the three test groups on the 3rd and 7th day (P<0.05), and a statistically significant difference of thrombosis between the three test groups on the 7 th day ( P<0.05 ) .The physical-chemical properties of drugs and use of time were factors in-fluencing inflammation reaction and thrombosis .

Objective: To investigate the source of Candida alb ic ans in the mouth of neonates. Methods: 208 mother in fant pairs were recruited. Specimens from mothers for fungal culture were obtain de from the mouths by oral rinse and from vagina by swab within 48 h before de livery, and specimens from full term neonates were obtained from mouth by swab on the 1st, 3rd and 5th day while still in hospital and when the neonates were 1 month old. Candida species were identified by the routine microbiologica l methods, then Candida albicans isolated from mother infant pairs were com pared genetically by random amplified polymorphic DNA analysis (RAPD). Results: Candida albicans was isolated in the mouth of only 2 neonates (0.96%) and in the vagina and mouth of the corresponding 2 mothers in hospital.That was isola ted in the mouth of 43 neonates (21.39%) when they were 1 month old and in both vagina and mouth of 3 corresponding mothers and in the mouth of another 2 corr esponding mothers. RAPD revealed different genotypes of Candida albicans in each mother infant pair. Conclusions: The vertical tran smission of Candida albicans from mother to baby seems not to be the main so urce of Candida albicans in neonate mouth.

Background and purpose:Curcumin is the major effective component of curcuma,curcumin has been noted to be able to selectively inhibit proliferation and induce apoptosis in tumor cells. Interferon-?(IFN-?) is one of the most important cytokines used in clinical treatment nowadays. This study was made to investigate the inhibitory effect of interferon-?(IFN-?)and curcumin on Raji cells (B-NHL) and discuss their mechanism.Methods:The variations of morphology of Raji cells were observed in culture medium after being treated by IFN-?(500,100,2000U/L) combined with various concentrations of curcumin (6.25,12.5,25?mol/L), cells were incubated with the compounds for variable times.The inhibitory ratio was measured by MTT assay, apoptosis was quantitated by flow cytometry(FCM) and the expressions of caspase6, caspase8 and caspase9 in Raji cells were detected by Western blot.Results:both IFN-? and curcumin could significantly induce apoptosis and inhibit the proliferation of Raji cells, synergistic effects were found if cells were treated by the combination of IFN-? and curcumin. The overexpressions of caspase6, caspase8 and caspase9 in Raji cells could be observed in a time-and dose-dependent manner.Conclusions:The combination of IFN-? and curcumin could synergistically inhibit proliferation and induce apoptosis, and its potential mechanism is probably associated with upregulating the expressions of caspase6, caspase8 and caspase9 in B-NHL Raji cell.

Objective To discuss the modern surgical treatments for congenital choledochal cysts complicated with anomalous junction of pancreaticobiliary ductal system through analyzing data in 30 cases. Methods The 30 cases were diagnosed with ERCP, MRCP, cholangiography or dissection, respectively. Then 28 of them were treated with external drainage (n=2), internal drainage (n=9) and Roux-en-Y hepaticojejunostomy (n=22), respectively. Of the 28, 5 received operations twice. Results External drainage was helpful in emergency cases while internal drainage frequently resulted in recurrent cholangitis, choledocholith, anastomotic stenosis or cyst malignancy that needed to be operated on again. Choledochocyst resection and pancreaticobiliary shunt achieved satisfactory results. Conclusions Congenital choledochal cyst is usually complicated with anomalous junction of pancreaticobiliary ductal system (88.2%). As for its treatment, choledochocyst resection, pancreaticobiliary shunt and hepaticojejunostomy should be of the first choice.

At present, the level of diagnosis and treatment of early gastrointestinal cancer has a larger gap between China and developed countries. In recent years, the advent of new endoscopic imaging techniques has improved the detection rate of early gastrointestinal cancer. Along with this, endoscopic submucosal dissection(ESD) enables radical resection for early cancer. In this article, we discuss how to improve the level of endoscopic diagnosis and treatment of early gastrointestinal cancer.

Objective To compare the therapeutic effect of routine dose of calcitriol and large dose impulsion therapy on hemodialysis patients with secondary hyperparathyroidism(SHPT). Methods 48 uremic hemodialysis patients were divided into group A(routine group, n = 22) and group B(control group, n = 21 ). In group A,22 pa-tients were administered with calcitriol for 6 months at the dosage of 0.25～0.5μg/d,adding calcium agents simul-taneously;the patients in group B were not given calcitriol for economic reason. In group C,21 patients were given calcitriol twice a week at the dosage of 2μg/time after hemodialysis for 3 months. Results Comparing to group B,serum PTH,AKP in group A had no significant difference,but serum hypocalcium and hyperphasphate were partly corrected,symptoms of bone pain, muscular convulsion and akin pruriter were improved. Comparing to group A,serum hypocalcium and hyperphasphate in group C were corrected, serum PTH, AKP were significantly decreased( t=2.031,P<0.05;t =3.317,P<0.001),and no hypercalcium oecurred. Conelosion Routine dose of calcitriol can not control uremic-SHirr,while impulsion therapy with lower dose oral calcitriol is effective and safe.

Berberine (BBR) is a type of alkaloids isolated from Coptidis Rhizoma and Phellodendri Chinensis Cortex and has been used to treat bacterial gastroenteritis, diarrhea and other digestive diseases for more than 1 000 years. According to recent studies, berberine has been found to have multiple pharmacological activities, including lowering blood glucose and lipid, anti-inflammation, antioxidation, relieving type 2 diabetic nephropathy (DN), diabetic cardiovascular disease, diabetic peripheral neuropathy ( DPN) and other complications. In this article, the authors summarized the literature reports about the effects of BBR in lowering blood glucose and preventing and treating the above type 2 diabetes and its complications, in order to provide reference to further studies and promotion of BBR's application.
