On the basis of outpatients' medical records concerning primary liver cancer (PLC), data of 552 patients (with 2020 effective prescriptions) from the Outpatient Department of Changhai Hospital treated by Professor Ling Changquan were collected. The nature, flavor and meridian distribution of the herbs used in the prescriptions were summarized by frequency method, and the features of the herbs used according to syndrome differentiation were analyzed by logistic regression. The couple herbs used were analyzed by cluster analysis. All the data were analyzed in combination with the experience of the specialist. It showed that most of the frequently used herbs were herbs for invigorating the spleen to promote appetite, removing toxic materials to inhibit tumor growth, and activating blood circulation to dissipate blood stasis. These herbs are mostly of plain or cool nature, and mainly of sweet, bitter, or acrid taste. It also showed that the most frequently used herbs for qi deficiency were Astragalus membranaceus, Atractylodes macrocephala, and Pseudostellariae; Caulis Spatholobi and Chinese jujube for blood asthenia; Fructus Corni and Ophiopogon japonicus for yin deficiency; Agastache rugosa, Semen Plantaginis and Poria for water-dampness; cape jasmine fruit and baikal skullcap root for heat excess; peach seed and Radix Paeoniae Rubra for blood stasis; Curcuma wenyujin, Akebia trifoliata and Bupleurum chinese for qi stagnation. A total of 19 pairs of couple herbs were summarized by the cluster analysis.

Objective The effects of TPT on the induction of apoptosis of leukemia cells and the regulation of c-myc in mRNA and protein level. Methods RT-PCR method was adopted to examine the expressions of the genes and immune histochemistry for the proteins of c-myc in HL-60 cells treated with TPT of optimal concentration and time. Results After HL-60 cells by TPT of 0.15 μmol/L for 12 h, the expression of c-myc mRNA decreased markedly assayed by RT-PCR. There was a significant difference between the TPT group and the control group(0.17±0.03 vs 1.11±0.25, P <0.05), expressive c-myc protein decreased assayed by evidently immunohistochemistry. The percentage of positive cells expressing c-myc protein was a significant difference between the TPT treated group and the control group (19.67 % vs 68.33 %, P<0.05). Conclusion TPT down-regulates endogenic c-myc mRNA and c-myc protein in HL-60 cells.

BACKGROUND:Bone marrow mesenchymal stem cel s have immunomodulatory properties and have potential applications in immunosuppression. OBJECTIVE:To investigate the isolation and culture of bone marrow mesenchymal stem cel s and the immunoregulation of CD8+T lymphocytes. METHODS:Primary bone marrow mesenchymal stem cel s were isolated from Wistar rats by bone marrow adherence method. The primary cel s were purified by differential adherence and digestion, and col agen type I was added as extracel ular matrix to expand bone marrow mesenchymal stem cel s. Passage 2 bone marrow mesenchymal stem cel s at densities of 0, 1×103, 1×104 and 1×105/wel were co-cultured with CD8+T lymphocytes, fol owed by phytohemagglutinin stimulation for 68 hours. T lymphocyte aggregation and proliferation were detected by staining with staining with 5,6-carboxyfluorescein diacetate succinimidyl ester and MTT, respectively. RESULTS AND CONCLUSION:Different concentrations of bone marrow mesenchymal stem cel s had an inhibitory effect on T lymphocytes, but this effect was weakest for the cel s at the density of 1×103 per wel and strongest for the cel s at the density of 1×105 per wel . Obvious agglomeration was observed in the same media. The proliferation rates of CD8+T lymphocytes were (44.83±4.92)%, (31.94±6.28)%and (15.77±3.98)%, respectively, after co-culture with 1×103, 1×104, 1×105/wel bone marrow mesenchymal stem cel s. There were significant differences between groups (P<0.05). These results showed that primary rat bone marrow mesenchymal stem cel s could be obtained by direct adherence method of the whole bone marrow, and the cel s could be purified by differential adherence combined with digestion and control method. Bone marrow mesenchymal stem cel s could inhibit T lymphocyte proliferation in a concentration-dependent manner.

ObjectiveTo examine the effects of temsirolimus, an inhibitor of mammalian target of rapamycin, on bladder cancer cell lines T24 and BIU-87 in vitro and in vivo for purpose of evaluating the probability of mTOR targeted therapy for bladder cancer.MethodsAfter being treated by a different concentration of temsirolimus, T24 and BIU-87 cells were tested by MTT assay for cell proliferation activity.Cell cycle and apoptosis analysis were performed with flow cytometer. Wound scratch assay was used for cell migration activity and transwell motility assay. Western blot analysis was used to test the mTOR phosphorylation. Subcutaneous inoculation of 6-week-old nude mice was performed using 1 × 106 T24 cells in 50％ matrigel for both control (n = 10) and temsirolimus (n = 10) groups. The volume of tumors was examined and then the expression of Ki-67 was detected by immunohistochemistry.ResultsTemsirolimus significantly inhibited proliferation of T24 and BIU-87 cells in a dose- and time-dependent manner. After administration of temsirolimus on T24 and BIU-87 cell lines for 24 h, the rate of wound healing in 0 nmol/L groups were (88.9 ± 14. 1 ) ％ and ( 83.6 ± 16.3)％ , which were higher than in the 5 nmol/L groups, which were (42.7 ± 11.6) ％ and ( 36.9 ± 9.7 ) ％ ( P ＜ 0.05 ). In the transwell motility assay, the number of cells in the 0 nmol/L group was 26.5 ± 5.8 and 28.2 ± 4.6, which was higher than in the 5 nmol/L group ( 19.0 ±3. 8 and 21.3 ± 5.1, respectively) (P ＜ 0. 05). When temsirolimus was administered on T24 and BIU-87 cell lines for 48 h the percentages of cells delayed in phase G0/G1 in 5 nmol/L group were ( 77.46 ±6.11)％ and (73. 39 ± 4. 94)％ respectively, and higher than in the 0 nmol/L group, which were (65.99 ±5.01 )％ 、(60.15 ±3.98)％ (P ＜0.05). There was no statistically significant difference in the apoptosis rate between the two groups (P ＞ 0.05 ). In Western blot analysis, the ratios of p-mTOR/β-actin were 0.92 ±0.09 and 1.01 ± 0.08 in 0 nmol/L group, and higher than in the 5 nmol/L group (0.47 ±0.05、0.04 ±0. 01 ) (P ＜ 0.05 ). After administration of temsirolimus for 21 days, the tumor volume in nude mice in the control group were 351.1 ± 139.9 mm3 , which was larger than 351.1 ± 139.9 mm3 in the temsirolimus group ( P ＜ 0.05 ). The positive rate of Ki-67 expression was ( 67.3 ± 8.4 ) ％ in the control group, which was higher than in the temsirolimus group ( 35.5 ± 6.7 ) ％ ( P ＜ 0.05 ).ConclusionsThis study provides in vitro and in vivo evidence that temsirolimus may inhibit the viability of bladder cancer cells and temsirolimus could be exploited as a potential therapeutic strategy in bladder cancer.

ObjectiveThe clinical features of T1G3 bladder cancer and the risk factors of the recurrence,progression and death were studied. Methods One hundred and eighty-seven cases with T1G3 bladder cancer were diagnosed from 1998 to 2006 in the Institute of Urology of Tianjin.There were 162 males and 25 females in the study group.The average age was 66 years (35 -92 years).A clinical epidemiology study was carried out and prognosis information was collected.The risk factors were preliminary screened with Kaplan-Meier univariate analysis and then finally determined with multivariate Cox proportional hazards regression model. ResultsBased on a mean follow-up of 46 months (range,12 to 111 months),100 (53.5％) of the cases had a recurrence,61 (32.6％) cases progressed and 37( 19.8％ ) cases died.The 1-,2-,3-,5-year probability of tumor recurrence was 35.0％,60.0％,63.0％,65.0％.The 1-,2-,3-,5-year probability of disease progression was 12.0％,27.0％,34.0％,38.0％ and the 1-,2-,3-,5-year probability of death was 0,11.0％,17.0％,26.0％,respectively.The tumor size,number of tumors,immediately intravesical instillation and the first recurrence time ≤6 months were the risk factors associated with tumor recurrence of T1G3 bladder cancer.The tumor modality,cancer in situ,the first recurrence time ≤ 6 months and frequency of recurrence were the risk factors of disease progression.Only progression was a risk factor of death. ConclusionsTumor of T1G3 bladder cancer patients with features such as the tumor size ≥3 cm,tumor multiplicity,and first recurrence time ≤6 months were more likely to relapse.Immediately intravesical instillation could reduce the risk of recurrence.Cystectomy must be carried out early if the patient with T1G3 bladder cancer has the risk factors of progression such as the nodous tumor,tumor in suit,the first recurrence time ≤6 months and frequency of recurrence ＞ 1.

Objective To discuss the clinicopathologic and imaging features of multilocular cystic renal eell carcinoma(MCRCC). Methods The data of 8 cases(5 men and 3 women)MCRCC classified according to 2004 WHO criteria were reviewed retrospectively.The tumor was incidentally found in 5 out of 8 cases.Renal ultrasound and CT scans were available in all 8 cases.CT or enhanced CT scans showed a well-defined cystid mass with irregular thickening wall or septa in 7 cases,without visible nodules found.For treatment,open or laparoscopic radical and partial nephrectomy was done in those cases. Results Postoperative pathological findings confirmed the diagnosis of MCRCC.The mean greatest diameter of the tumors was 5.6 cm.Microscopically,the wall and septa lined by one or several layers of clear cells were observed in all cases.The TNM stage of all 8 cases was T1 N0 M0.For pathologic grade,7 cases were G1 and 1 case was G2.Seven patients were followed up and remained tumor free during the average time of 8 months. Conclusions MCRCC is an uncommon subtype of RCC,it has a lower malignant potential and a better prognosis compared with other types of RCC according to the literature.Nephron-sparing surgery may be an appropriate treatment option for MCRCC.

Objective To discuss the therapeutic methods of idiopathic retroperitoneal fibrosis (IRF). Methods Nineteen cases of IRF were reviewed.The main clinical menifestation included lamber pain and nephrohydrosis,nausea,loss of appetite,body weight descend,hypourocrinia,percussion tenderness over kidney region.The imaging showed soft tissue mass behind the peritoneum,which surrounded the abdominal aorta,and wrapped the ureter and inferior vena cava.There were 9 cases treated by open surgery,in 7 of which ureterolysis and placement into abdominal cavity were performed,and in the other 2 cases kidney fistulation was undertaken because of failure of ureterolysis.In 10 cases endoscopic stent of double J stent was taken.Glueocortieoid was given in 17 patients.Results Seventeen cases were followed up from 5 to 81 months.Six cases with ureterolysis were followed up,whose symptom disappeared and renal function recovered or kept slowly increasing state.In 2 cases undertaken kidney fistulation,urinary tract infection took place repeatedly after 3 months and 7 months respectively from operation.And 1 case needed hematodialysis therapy.There were 9 cases undertaken ureterai stent combined with prednisone were followed up,in whom hydronephrosis relieved obviously and serum Cr averaged 103±48μmol/L when keeping the double J stent.In 3 cases hydronephrosis recurred after removing the stent. Conclusions Ureterolysis and placement into abdominal cavity is the valid treatment of IRF.The way of endoscopic stent combined prednisone treated IRF is simple,which effect is satisfied in short term.
