OBJECTIVE:To investigate the effects of Shenfukang capsules on clinical efficacy and renal function indexes of patients with renal insufficiency. METHODS:Totally 100 inpatients with renal insufficiency treated by Shenfukang cap-sules in the First Affiliated Hospital of Guangxi Medical University during Feb. to Mar. 2015 were analyzed retrospectively in respects of general information of patients,therapy plan,renal function indexs before and after treatment and clinical effica-cy. The relationship of clinical efficacy with age and duration was also analyzed. RESULTS:There were 33 cases of acute re-nal insufficiency and 67 cases of chronic renal insufficiency. The route of administration of Shenfukang capsules was oral ad-ministration(97 cases,97.00%),the main dosage was 6 capsule/d(36 cases,36.00%),and treatment duration were 0-<7 days(39 cases)and 7-<15 days(49 cases). After treatment,the average serum creatinine concentration was lower than be-fore treatment,while mean GFR and Ccr were higher than before treatment,with statistical significance(P<0.05). The total response rate was 72.00%,and response rate of patients with acute renal insufficiency was 87.88% and significantly higher than 64.18% of patients with chronic renal insufficiency,with statistical significance(P<0.05). Among patients with ≤60 years old,the total response rate of patients with acute renal insufficiency was significantly higher than that of patients with chronic renal insufficiency,with statistical significance(P<0.05);among patients elder than 60 years old,there was no statistical significance in therapeutic efficacy between acute renal insufficiency and chronic renal insufficiency(P>0.05);among patients with chronic renal insufficiency,the total response rate of patients elder than 60 years old was significantly better than that of patients with ≤60 years old,with statistical significance (P<0.05). With the extension of treatment duration,the total response rate of patients with acute renal insufficiency was on the rise,and that of patients with chron-ic renal insufficiency increased first and then decreased. No obvious ADR was found during treatment. CONCLUSIONS:Shenfu-kang capsules can improve renal function in patients with renal insufficiency,and has definite curative effect on acute and chronic renal insufficiency with good security. The clinical efficacy may be related to age and treatment course.

Objective To investigate the clinical value of transthyretin (TTR) from patients with early rheumatoid arthritis (ERA). Methods 58 patients with ERA , 34 patients with later RA (LRA) and 34 healthy control (HC) were included in the research. TTR was analyzed by ELISA, whose variance was analyzed. TTR density, disease activity score28 (DAS28) score and rheumatoid factor (RF) were tested, and their correlation with TTR was analyzed. Results Serum level of TTR with ERA significantly increased compared with that with LRA and HC (P < 0.05), no statistical significance with LRA group and HC. TTR level was no correlation with the number of swelling and tender joints, disease activity score 28, RF, ESR, CRP, anti-cyclic citrylinated peptide antibody and anti-keratin antibodies, hemoglobin, thrombocyte and albumin. Conclusion Serum level of TTR significantly increased with ERA patients, contributing to early diagnosis for RA.

Objective: To study the features of spontaneous isolated superior mesenteric artery dissection (SISMAD) by unexpected detection of renal artery dual-source CT (DSCT) imaging in hypertension patients. Methods: A total of 4107 patients with suspected secondary hypertension received renal artery DSCT examination in our hospital from 2010-03 to 2015-04 were studied and SISMAD was unexpectedly found in 12 patients. There were 3 patients with mild abdominal pain and the rest without obvious abdominal symptoms. The position and length, true and false lumens, detached tunica intimal flap and branch involvement of dissection, intestinal wall edema and ileus were recorded. Results: SISMAD in all 12 (0.3%) patients were found unexpectedly. Axial CT with post-processing technique clearly displayed the ruptured tunica intimal orifice, true and false lumens, detached intimal flap; the branches were all originated from true lumen. According to Sakamoto classification, all 12 patients were belong to Type I as the true and false lumens were with an entry and re-entry respectively, no filling defect in false lumen. The distance from orifice of dissection to root of abdominal aorta was (26.7 ± 11.3) mm and the length of dissection was (35.1 ± 11.7) mm.There were 10 patients with aneurysmal expansion with the diameter of (11.9 ± 2.5) mm. Conclusion: Unexpected detection of SISMAD by renal artery CT imaging was about 0.3%, radiologist should pay special attention to find superior mesenteric artery dissection in hypertension patients.

Objective To evaluate the correlation between ultrasonography and histopathology in acute lung injury of rats.Methods Twenty male Wistar rats were randomly divided into control group (4 rats) and experimental group (16 rats),in the experimental group acute lung injury models were step-by-step induced by oleic acid (OA) and sequentially by OA and lipopolysaccharide (LPS).After the end of each step of models,ultrasound examination was applied,and the rats were sacrificed to take the lung specimens to be observed.The ultrasonography and pathological results were analyzed,and the numbers of alveolar were counted under microscope (200 times).Results With the aggravation of acute lung injury,the sonographic findings showed unclear or disappeared pleural line,close-set of B-lines,and pulmonary consolidation with air bronchogram.For control group,the ultrasonographic score was 0.25 ± 0.50,lung injury pathological score was 0.50 ± 0.58,and the numbers of alveolar were 25 ± 3.For OA group,the ultrasonographic score was 2.86-± 1.35,lung injury pathological score was 6.28-± 0.76,and the numbers of alveolar were 10-± 2.For OA + LPS group,the ultrasonographic score was 5.83-± 2.32,lung injury pathological score was 9.83 ± 0.98,and the numbers of alveolar were 6-± 2.All 3 groups were significant different on ultrasonographic score,pathological score and alveolar counts (P ＜ 0.01).Conclusions The ultrasonography image of acute lung injury of rats were positively correlated with its histopathological alteration.The ultrasonography can effectively evaluate the degree of acute lung injury of rats.

ObjectiveTo investigate the relationship between metastasis-associated gene 1 ( MTA1 )expression and invasive and metastatic ability of cervical cancer cell. MethodsThree kinds of plasmids pcDNA3( control group), pcDNA3-MTA1 ( MTA1 group) and pSilencer3. 1-MTA1-siRNA ( MTA1-siRNAgroup) were transfected into human cervical cancer cell line CaSki cells. Reverse transcription (RT)-PCR and western blot were used to detected MTA1 mRNA and protein expressions. The effects of MTA1 expression on CaSki cell growth and proliferation, cell migration, adhesion and invasion, and cell cycles were tested by methyl thiazolyl tetrazolium (MTT), clone formation experiment, wound-healing assay, transwell assay, adhesion assay and flow cytometry, respectively. In animal experiment, three groups of cells were inoculated to BALB/c nude mouse subcutaneously to observe tumor formation ability. ResultsCompared with control group, MTA1 mRNA and protein were significantly overexpressed in MTA1 group, while MTA1-siRNA group showed lower MTA1 expression. Compared with control group, MTA1 group showed significantly accelerated cell growth; while MTA1-siRNA group showed decreased cell growth since the second day (P＜0. 05). Clone formation number in control, MTA1 and MTA1-siRNA group were 133 ±6, 169 ± 10 and 57 ±5,respectively. MTA1 group showed accelerated cell formation, while MTA1-siRNA group showed the reverse effect compared with that in control group(P ＜ 0. 05 ). At 24, 48 and 72 hours after wounding, the healing ability of MTA1-siRNA group significantly lagged behind that in the control group, while MTA1 group showed accelerated cell healing ability. The adhesion rate of control, MTA1 and MTA1-siRNA group were (69. 3 ± 3. 6) ％, ( 80. 4 ± 5. 6 ) ％ and ( 39. 2 ± 7.4 ) ％ separately at 90 minutes after cell seeding. In contrast with control group, MTA1 group promoted the adhesion of CaSki cell to matrigel matrix, while MTA1-siRNA group inhibited the adhesion process (P ＜0. 05 ). In the migration assay, the number of cells migrated to the bottom side of the membrane in control,MTA1 and MTA1-siRNA group were 153 ± 17,247 ± 38 and 82 ± 10, respectively. The number of cells in the invasion assay were 231 ± 19,354 ± 36 and 76 ± 7, respectively. Compared with the control group, MTA1 group significantly increased the migration and invasion ability, while MTA 1-siRNA group showed lower cell migration and invasion ability (P ＜ 0. 05 ). In cell cycle experiment, no significant differences of cell proportions including G1, S and G2 stage were found among three groups (P ＞ 0.05).In animal experiment, compared with control group,MTA1 group showed accelersted tumor formation and growth,whilethe MTA1-siRNA group showed the reverse effect ( P ＜ 0. 05 ). ConclusionsMTA1 may play its roles to promote cervical cancer cell invasion, migration, adhesion, as well as cell growth and colony formation, while RNA interference against MTA1 may decrease the malignant phenotypes. This study shows that it will be an effective beginning to explore metastasis mechanisms and cancer gene therapy strategy targeting MTA1 in cervical cancer.

Objective To explore the pregnancy outcomes of women with pancytopenia and the risk factors for the adverse perinatal outcomes.Methods A total of 106 pregnant women with pancytopenia were admitted to Peking University People's Hospital from Jan.2005 to Sep.2014.The clinical data and the pregnancy outcomes were reviewed retrospectively to investigate the risk factors for the adverse perinatal outcomes.Results (1)Eighty-four patients were found pancytopenia before pregnancy while 22 were found for the first time during pregnancy.Sixty-four patients were diagnosed as aplastic anemia;30 as myelodysplastic syndrome;2 as paroxysmal nocturnal hemoglobinuria;4 as hypersplenism,and 1 as anti-phospholipid syndrome.Diagnoses of the remaining 5 patients were uncertain.(2)Sixty-nine patients received at least one time blood transfusion before delivery.(3) As for the complications,nine women developed gestational diabetes;twenty-two suffered severe preeclampsia (SPE);two were diagnosed as anemic heart disease and three experienced respiratory tract infection.The postpartum blood loss ranged from 50 ml to 3 800 ml,with the median of 400 ml.And six women had the blood loss more than 1 000 ml.The gestational age at delivery ranged from 24 weeks to 40 weeks,with the median of 37.0 weeks.(4)Thirty-one patients suffered adverse perinatal outcomes,including 3 cases of intrauterine death,4 therapeutic labor induction before 28 gestational weeks,6 premature delivery before 34 weeks.There were 2 neonates complicated with intracranial hemorrhage,2 with neonatal respiratory distress syndrome,3 with hypoxic-ischemic encephalopathy,2 with severe asphyxia and death,and 14 with small for gestational age.Among the patients with adverse perinatal outcomes,26 women received blood transfusion during pregnancy and 17 developed SPE.The maximum and the minimum value of their white cell count (WBC),hemoglobin concentration (Hb) and blood platelet count (BPC) were (4.9± 1.4)× 109/L,(2.9±0.8)× 109/L,(88.6± 14.9) g/L,(57.9 ± 14.5) g/L,(47.7±27.4)× 109/L and (11.9 ± 12.3)× 109/L,respectively.For those patients without adverse perinatal outcomes,43 received blood transfusion during pregnancy and 5 developed SPE.The maximum and the minimum value of their WBC,Hb and BPC were (5.2±1.5)×109/L,(3.2±0.9)×109/L,(101.4±16.2) g/L,(71.9 ± 14.5) g/L,(52.3 ± 24.0)× 109/L and (19.0 ± 12.1)× 109/L,respectively.The multivariate regression analyses indicated that SPE,Hb less than 70 g/L and BPC less than 20× 109/L were the independent risk factors for the poor perinatal outcomes in pregnant women with pancytopenia (P＜0.05).Conclusions The incidence of adverse perinatal complications increased dramatically in pregnant women with pancytopenia.Concurrent SPE,minimum Hb less than 70 g/L and minimum BPC less than 20 × 109/L may be the independent risk factors for the adverse perinatal outcomes.

OBJECTIVE: To discuss the effects of single dose of cisplatin on renal interstitial fibrosis indicators in rats dynamically. METHODS: 72 SD rats were randomly divided into normal group and cisplatin group, with 36 rats in each group. Normal group and cisplatin group were given equal volume of normal saline and cisplatin 5 mg/kg intraperitoneally on the first day, respectively. Each 6 rats were sacrificed on 8th, 14th, 30th, 50th, 60th, 90th day. The serum levels of blood urea nitrogen (BUN) and creatinine (Cr) were determined, and the degree of renal tubulointerstitial injury and relative area of renal tubulointerstitial fibrosis were evaluated. The expression of α-smooth muscle actin (α-SMA), type Ⅰ collagen (Col Ⅰ) and transforming growth factor β1 (TGF-β1) were determined in renal tissue. RESULTS: Compared with normal group, the serum levels of BUN and Cr, renal tubulointerstitial injury indexes, relative area of renal tubulointerstitial fibrosis, and the expression of α-SMA, Col Ⅰ and TGF-β1 in renal tissue were increased significantly (P<0. 05 or P<0. 01). In cisplatin group, within the 8th-90th days, serum level of BUN in rats had no significant change; serum level of Cr, renal tubulointerstitial injury indexes, renal tubulointerstitial fibrosis, the expression of a-SMA, Col Ⅰ and TGF-β1 in renal tissue increased first and then decreased. CONCLUSIONS: A single dose of clinical dose of cisplatin can induce renal interstitial fibrosis in rats, and its mechanism may be related to the expression of TGF-β1 in renal tissue.

Pituitary adenoma is one common type of intracranial tumors, accounting for about 10% of intracranial tumors. Although pituitary adenomas are benign tumors, the complete resection and recurrence prevention remain challengeable due to aggressive growth of tumor, limited equipment conditions and surgical techniques of the surgeon. The proportion of recurrent pituitary adenomas is rising year by year and the difficulty of treatment also increases. This article reviews the diagnosis and treatment of recurrent pituitary adenomas based on the summary data of invasive or recurrent pituitary adenomas cases in our center, including indication for the second transsphenoidal surgery, surgical techniques, and prevention and treatment of postoperative complications, to provide reference for clinicians in this field.

OBJECTIVETo evaluate the antitumor efficacy of proliferating cell nuclear antigen antisense oligonucleotide (PCNA-ASO) in combination with recombinant adenovirus p53 (Ad-p53) against bladder cancer EJ and BIU-87 cells in vitro and in vivo.

METHODSCells were transfected with Ad-p53 (100 MOI), and PCNA-ASO (1.6 micro mol/L) was then introduced into the cells using a cationic lipid (lipofectamine, 20 micro l/ml). In vitro and in vivo antitumor effects of combining PCNA-ASO with Ad-p53 were measured using the MTT assay, flow cytometry, clone formation, and a nude mice model.

RESULTSThe combination of PCNA-ASO and Ad-p53 inhibited cell viability in both the EJ (89.3%) and BIU-87 (78.6%) cell lines. The ability of the cells to form foci was also reduced by 74.8% in EJ cells and by 67.5% in BIU-87 cells (P < 0.01). A significant decrease of cells in the S phase (11.4% in EJ cells, 14.6% in BIU-87 cells) and a significant increase of cells in G1 phase (62.2% in EJ, 56.8% in BIU-87) were noted. The mean tumor volume after 7 days of treatment with PCNA-ASO or Ad-p53 in combination decreased to 47.6% or 36.4% of the initial tumor size in the two cell lines respectively.

CONCLUSIONThese results indicate that combined PCNA-ASO and Ad-p53 in the treatment of bladder cancer with mutant p53 has important therapeutic potential, significantly suppressing the growth of human bladder cancer both in vitro and in vivo.
