The main feature of acute steroid-resistant rejection (ASRR) after liver transplantation is a lack of response to steroids.Although some effective immunosuppressants are available,there is no uniform treatment presently available.This paper will focus on exploring the mechanism of ASRR and formulating individually approached strategies.
2. Determination of the content of rocuronium bromide by HPLC
Journal of International Pharmaceutical Research 2010;37(2):127-129
Objective: To establish a HPLC method to determinate the content of rocuronium bromide. Methods: NH2-bonding silica gel was used as the stationary phase. The mobile phase consisted of 0.04 mol/L tetramethyl ammonium hydroxide (pH adjusted to 7.4 by phosphoric acid) and acetonitrile (10:90). The column temperature was 35°C. The detection wavelength was 207 nm. Results: The relation between concentration and peak area was linear in the range of 0.1251-2.0065 mg/ml with r2 of 0.9999. The average recovery rate was 99.9% with RSD of 0.1%. Conclusion: This method is exclusive, sensitive and is reliable for the determination of rocuronium bromide.

Ojective To study the diagnosis and treatment of upper extremity edema after radical mastectomy. Methods Diagnosis depended on B type ultrasoundgraphy, CT, lymphography, venography, biopsy and axilla exploration. Lymphaticovenous anastomosis (LVA) with microsurgery technology was used for the treatment of simple lymphoedema. Results In 40 cases of lymphoedma after radical mastectomy, 7 patients were diagnosed as metastasis of cancer. 3 patients were diagnosed obstrcution of lymphatic and vein. 30 patients with simple lymphedema were treated with LVA. Short term efficacy was observed in all patients.The efficacy at 3~12 years was 83.3%. Conclusion The diagnosis of upper limb edema after radical mastectomy is essential. Metastasis and obstruction of vein are the causes. Biopsy conducted under high frequency B type ultrasoundgraphy may be a good method for the diagnsosis of matastasis, but a few patients were diagnosed only by axilla exploration. LVA may be given first priority to the theraphy of lymphedema after radical mastectomy.

The standardized resident training is an important part of continuing medical education in China,which plays a vital role in the cultivation and development of doctors.At present,the standardized resident training system in our country is at an exploratory stage and different from those advanced countries.This paper contrastively analyzed the domestic and foreign standardized resident training modes from the perspectives of education patterns,training years,training organizations,training contents,assessments,and financial sources.By learning from the advanced experience of those foreign countries,it provided the reference for the standardized resident training system in China.

Objective To evaluate the diagnosis and therapy of intestinal lymphangiectasia.Methods In this study 15 patients were admitted in our hospital during recent 7 years.Clinical manifestations included hypoalbuminemia,symmetrical edema,emaciation,diarrhea and lymphopenia.Lymphangiography,lympanscintigraphy and biopsy were performed for diagnosis.Therapy conducted included conservative therapy,low-fat and medium-chain triglycerides(MCT)diet,albumin infusions,diuretics,total parenteral nutrition and octreotide.Surgical therapy ineluded thoracic duct-vein anastomasis and segmental resection.Results In this group 8 patients receiving conservative therapy were followed-up from 1.5 to 7 years(average 2.5 years).Symptoms were alleviated in 6 patients.Seven patients underwent operative therapy,among them,4 patients received thoracic duct-exterior jugular vein anastomasis and followed-up from 1 to 5 years,with symptoms mitigated in 2 patients.3 patients underwent local intestinal resection,follow-up from 1 to 3 years found one patient was cured,one was improved,and 1 patient died 3 months afterthe operation. Conclusion Intestinal lymphangiectasia is rather rare and there was no definite and effective therapy.

Gallbladder cancer (GBC) is the most common malignancy of the biliary tract.Most patients are diagnosed at the advanced stage,missing the optimal chance for curative surgery,thus leading to the fact that GBC is usually associated with poor prognosis.It is very crucial to strengthen the basic research on GBC,which may further improve the diagnosis and treatment.The research updates on the related genes in the initiation and progression,molecular mechanism of lymphatic metastasis,and tumor microenvironment of GBC in recent years were reviewed in this paper.

Objective Tumor cells are able to support their malignant proliferation by changing metabolic models .Prostate cells rely much on lipid metabolism in which ATP-citrate lyase ( ACLY) plays a very important role .The aim of this research was to study the effects of downregulated ACLY on the cell proliferation , cycle distribution and apoptosis of androgen-independent prostate cancer cells DUl45. Methods DU145 cells were divided into two groups:the cells in experiment group were transfected with the small interfering RNA-mediated knockdown of ACLY , while the cells in control group were transfected with meaningless small interfering RNA.Cell counting Kit test ( CCK-8 ) was applied to detect the effects of the downregulation of ATP citrate lyase on the proliferation of DU145.Flow cytometry instrument was used to analyze the variation of cell cycle distribution and apoptosis rate between groups .Western blot was used to detect the change of intracellular Caspase-3 protein content. Results Western blot showed favorable effects of ACLY interference .Compared with control group , ACLY protein content significantly decreased in experiment group ( P<0.05) ;the acetyl coenzyme A content and the percentage of early apoptosis cells and late apoptosis cells increased significantly [(0.42±1.99) vs (0.79±2.38), (37.10±3.28) vs (6.20±2.88), P<0.05].As to the selec-tive ACLY knockdown in DU145 cells, the proliferation ability in experiment group weakened in comparison with control group , which became more and more apparent as time went on .At 48h and 72h time points, the cell absorbance between two groups at the same time point was of significant difference (P<0.05).As to the interfering ACLY expression in DU145 cells, the percentage of G1 cells in-creased without any statistical significance (P>0.05), while the percentage of G2 cells decreased and the percentage of S cells in-creased with most cell cycle blocking at G 0/G1 stage, which were of significant difference .Meanwhile the expression of apoptosis pro-tein Caspase-3 upregulated significantly . Conclusion ACLY is of vital significance to maintain the malignant proliferation of prostate cancer cells and its downregulation results in the inhibition of cell proliferation and the promotion of cell apoptosis .

In order to research into the relationship between atrial natriuretic peptide (ANP), aldosterone (Aldo) and pregnancy-induced hypertension (PIH), as well as normal pregnancy, the plasma concentrations of ANP and Aldo from normal pregnant women. PIH patients and their fetuses were measured by radioimmunoassay. It was found that maternal venous Aldo and ANP were higher in normal pregnant women than those in non-pregnant women. The plasma ANP was higher in PIH patients than that in normal pregnant women while plasma Aldo was lower. The plasma concentration of ANP was higher in the fetuses of PIH patients than that in the normal controls, but Aldo was lower. It is concluded that ANP concentration correlates significantly to the severity of PIH, and may be used for an early diagnosis of PIH.
