OBJECTIVETraditional Chinese medicine (TCM) is regarded as an important treatment for gastric cancer patients, especially for those in advanced stage. To evaluate the effects of TCM treatment on gastric cancer patients, the authors performed a retrospective study to report the result of the integrated treatment of TCM with chemotherapy for stage IV non-surgical gastric cancer.

METHODSIn this study, 182 patients with stage IV and non-surgical gastric cancer were retrospectively analyzed to evaluate the effects of TCM integrated with chemotherapy. Among the 182 cases, 88 cases received integrated therapy consisting of TCM and chemotherapy, while 94 cases received chemotherapy alone. The overall survival and Karnofsky performance status (KPS) score were measured as the main outcome.

RESULTSThe median overall survival of the integrated therapy group and chemotherapy group were 16.9 and 10.5 months, respectively. The 1-, 3- and 5-year survival rates of integrated therapy group vs. chemotherapy group were 70% vs. 32%, 18% vs. 4%, and 11% vs. 0%, respectively. There was a significant difference between the two groups (χ= 42.244, P > 0.001). After six-month treatment, KPS scores of the integrated therapy group and the chemotherapy group were 75.00 ± 14.78 and 60.64 ± 21.39, respectively (P > 0.001). The Cox regression analysis showed that TCM treatment is a protective factor for patients' overall survival.

CONCLUSIONThis study demonstrated that TCM integrated with chemotherapy may prolong overall survival and improve survival rate and life quality of patients with stage IV non-surgical gastric cancer.

OBJECTIVETo observe the effect of sensory neuropeptide substance P combined with epidermal stem cells (ESC) on wound healing and nerve regeneration in diabetic rats.

METHODSESC that had been isolated from SD rats were identified and cultured in vitro, and they were inoculated onto nourishing layer of amniotic membrane to construct amniotic membrane-ESC. Four full-thickness skin wounds were produced on the back of each of 48 diabetic rats. The resulted 192 wounds were randomly divided into ESC + substance P group, ESC group, substance P group, and control group according to the lottery method, with 48 wounds in each group. Wounds in ESC + substance P group and ESC group were transplanted with amniotic membrane-ESC, and those in substance P group and control group were transplanted with amniotic membrane. After transplantation, 250 µL substance P in the concentration of 1 × 10(-7) mol/L was injected around and into the middle of the wounds in ESC + substance P group and substance P group, 2 times a day, and continued for 4 days, while 250 µL PBS solution was injected in the above-mentioned position in ESC group and control group as control, 2 times a day, and continued for 4 days. On post injury day (PID) 4, 7, 10, 14, 17, and 23, the wound healing rate (with 8 wounds at each time point) was observed and determined, and changes in wound tissue structure were observed with HE staining. On PID 4, 7, and 10, collagen distribution in wound tissue was observed with Masson staining, and type I and type III collagen deposition in wound tissue was respectively observed after immunohistochemical staining. The distribution of protein gene product 9.5 (PGP 9.5) and regeneration of substance P positive nerve fibers in wound tissue were observed with immunohistochemical staining on PID 14 and 23. Data were processed with one-way analysis of variance and t test.

RESULTS(1) The wound healing rate in ESC + substance P group reached 100.0% on PID 14, which was obviously earlier than that in ESC group, substance P group, and control group, healing was respectively observed on PID 17, 17, and 23. The wound healing quality in ESC + substance P group was better than that in the other three groups as shown by HE staining. (2) On PID 10, collagen that was darkly stained and widely distributed was observed in wound tissue of ESC + substance P group and substance P group, while collagen in the other two groups was lightly stained and narrowly distributed. Deposition quantity of type I collagen gradually increased, and that of type III collagen gradually decreased in the wounds of each group over time. On PID 4, 7, and 10, distribution amount of type I collagen in wound tissue of ESC + substance P group was significantly higher than that in ESC group (with t value respectively 32.72, 118.21, 26.71, P values all below 0.01) and control group (with t value respectively 44.37, 22.76, 30.32, P values all below 0.01), while there was no significance between ESC + substance P group and substance P group. On PID 4, 7, and 10, distribution amount of type III collagen in wound tissue of ESC + substance P group was significantly higher than that in ESC group (with t value respectively 32.27, 28.68, 14.51, P values all below 0.01) and control group (with t value respectively 35.68, 22.52, 22.24, P values all below 0.01). (3) A large amount of PGP 9.5 and regeneration of substance P positive nerve fibers, and some peripheral nerve fibers in deep wound extending to epidermis were observed in wound tissue of ESC + substance P group and substance P group. A small amount of PGP 9.5 and regeneration of substance P positive nerve fibers without peripheral nerve fibers extending to epidermis were observed in deep wound tissue of ESC group and control group. On PID 14, 23, ratios of area of PGP 9.5 positive nerve fiber in the wounds of ESC + substance P group were (3.86 ± 0.25)% and (7.03 ± 0.28)%, and they were significantly higher than those of ESC group [(1.48 ± 0.30)%, (3.01 ± 0.43)%, with t value respectively 23.95, 30.27, P values all below 0.01] and control group [(1.46 ± 0.23)%, (2.84 ± 0.29)%, with t value respectively 27.35, 40.32, P values all below 0.01]. On PID 14, 23, ratios of substance P positive nerve fiber area in the wounds of ESC + substance P group were (2.01 ± 0.14)% and (1.19 ± 0.11)%, which were obviously higher than those of ESC group [(0.85 ± 0.17)%, (1.34 ± 0.21)%, with t value respectively 20.50, 2.60, P < 0.05 or P < 0.01] and control group [(0.74 ± 0.15)%, (1.30 ± 0.17)%, with t value respectively 23.98, 2.41, P < 0.05 or P < 0.01].

CONCLUSIONSJoint application of substance P and ESC can effectively promote healing of wound and nerve regeneration in diabetic rats.

OBJECTIVETo evaluate the outcomes of childhood acute monocytic leukemia (AML-M5) and explore the indications of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for children with AML-M5.

METHODSeventy-five AML-M5 patients and 201 non-AML-M5 AML patients were enrolled in this retrospective analysis. Event-free survival (EFS) and overall survival (OS) rates were estimated by Kaplan-Meier method and prognostic factors were evaluated by COX regression with SPSS.

RESULT(1) Twelve patients gave up treatment after confirmed diagnosis. Two patients died on the second day after chemotherapy. Of the 61 patients, 73.8% (45/61) achieved complete remission (CR) after two courses of chemotherapy. The 5-year EFS rate was 34.5% ± 6.8%. But of the 117 non-AML-M5/M3 AML patients, the 5-year EFS rate was 51.0% ± 4.9%. (2) Multivariate analysis showed that age ≥ 10 y, the proportion of bone marrow blast cell counts ≥ 15% after the first induction therapy, not CR after two courses of chemotherapy were risk factors for the long-term prognosis. (3) Of the 20 patients whose bone marrow blast cell counts ≥ 15% after the first induction therapy, 5 patients who choose allo-HSCT had a better OS than the other 15 patients who choose chemotherapy only (60.0% ± 21.9% vs. 7.3% ± 7.1%, P = 0.024).

CONCLUSIONChildren with AML-M5 had a poorer prognosis than the other AML patients; patients whose bone marrow blast cell counts ≥ 15% after the first induction therapy chose allo-HSCT had a better prognosis. At present, there is no enough evidence to support that patients whose bone marrow blast cell counts < 15% after the first induction therapy should choose unrelated donor for allo-HSCT.

The present study was purposed to investigate the inhibition effect of tumor necrosis factor-related apoptosis inducing ligand (TRAIL) on growth of RPMI8226 cells and adhesion between RPMI8226 cells and bone marrow stroma cells (BMSC), and to explore its mechanism as well. The inhibition effects of TRAIL on cells growth and adhesion were assayed by MTT; cell apoptosis was detected by Annexin V and PI; expression of genes bax, bcl-2, mcl-1, CARP1, CARP2, XIAP and cFLIP were determined by semi-quantitative RT-PCR; apoptosis-related protein expression was detected by Western blot. The results showed that TRAIL inhibited the proliferation of RPMI8226 cells in dose- and time-dependent manners. TRAIL induced apoptosis in RPMI8226 cells, the expression level of genes bcl-2, mcl-1, CARP1, CARP2, XIAP and cFLIP decreased, while the expression level of Bax increased, but the expression level of caspase-3 and NF-kappaB P65(RelA) proteins decreased. Moreover, TRAIL up-regulated the expression level of adherent molecule CXCR4 in RPMI8226 cells significantly. It is concluded that TRAIL up-regulated the expression level of adherent molecule CXCR4 in RPMI8226 cells significantly, and induced the apoptosis of RPMI8226 cells. Growth inhibition effect of TRAIL on RPMI8226 cells is in dose- and time-dependent manners.

OBJECTIVETo probe into the occurrence rates of the effective antigen combinations which were used to detect the minimal residual disease (MRD) by flow cytometry in childhood B-lineage acute lymphoblastic leukemia (B-ALL), as well as the relationship between clinical-biologic factors and different combinations.

METHODSAmong the 327 B-ALL children enrolled in our study, 289 cases were identified with at least one antigen combination as MRD marker. Their bone marrow samples were monitored by using 9 combinations with 4 antigens each, analyzed the occurrence rates and compared them with international reports. Also the differences in the distribution of each antibody combination in the different clinical-biologic groups were compared by the chi-square test and Fisher's exact test.

RESULTS(1) Totally 327 cases of childhood B-ALL were screened for antibody combinations of interest and 88.4 percent of them (289 cases) were identified with effective antibody combinations. (2) The occurrence frequencies of antigen combinations were different. The highest frequency was seen with TdT/CD10/CD34/CD19 combination which was 70.59 percent. Expressions of antigen combinations in Chinese children were different from those in western countries. (3) Some antibody combinations presented different frequency among different clinical groups. CD38/CD10/CD34/CD19 was expressed more often in samples of relapsed patients (P = 0.045). CD66c/CD10/CD34/CD19 expression was significantly higher in BCR/ABL positive group (P = 0.037) and relapsed patients group (P = 0.047). TdT/CD10/CD34/CD19 was expressed more in MLL-AF4 negative group (P = 0.005) and Prednisone Good Response group (P = 0.002). CD58/CD10/CD34/CD19 was correlated with low relapse rate (P = 0.032).

CONCLUSION(1) The coverage rate of 9 antigen combinations in our study was 88.4%. The occurrences of frequency of different antibody combinations in B-ALL were different, and also different from that of western countries. The occurrence frequencies of antibody combinations CD21/CD10/CD34/CD19, CD22/CD10/CD34/CD19, CD10/CD56/CD34/-CD19 and TdT/Cu/CD34/CD19 were lower than those of the western report, while CD38/CD10/-CD34/CD19, CD45/CD19/CD10/CD34, CD58/CD10/CD34/CD19 and CD66c/CD10/CD34/CD19 were similar to those of the reports from western countries. (2) TdT/CD10/CD34/CD19 may work as a simplified method to detect MRD in Chinese population. (3) The occurrence frequency of CD38/CD10/CD34/CD19, CD45/CD19/CD10/CD34, CD58/CD10/CD34/CD19, TdT/CD10/CD34/CD19 could be effective remediation and evidence to evaluate the remission quality and guide the therapy, especially for those with no original MRD marker record. (4) CD58/CD10/CD34/CD19 and TdT/CD10/CD34/CD19 may correlate with good prognosis, but CD66c/CD10/CD34/CD19 and CD38/CD10/CD34/CD19 may predict poor prognosis. These results might contribute to individual risk evaluation and guide the therapy selection.

This study was aimed to investigate the effect of recombinant mutant human TNF-related apoptosis-inducing ligand (rmhTRAIL) combined with As(2)O(3) on inducing apoptosis of adriamycin-resistant leukemia cell line K562/A02 (mdr-1(+)). The morphologic changes of cells treated with rmhTRAIL were observed by inverted microscope, taking adriamycin-sensitive cell line K562 (mdr-1(-)) as control; the inhibitory rate of cell proliferation after being treated with rmhTRAIL, As(2)O(3) alone or combined was assayed by MTT method; the apoptosis peaks of K562/AO2 and K562 were quantitatively detected by flow cytometry with PI staining after being treated with rmhTRAIL, As(2)O(3) alone or in combination. The results indicated that the inhibition effect of rmhTRAIL and As(2)O(3) in combination on K562/AO2 and K562 cells was higher than that of riTRAIL and As(2)O(3) alone (p < 0.01), rmhTRAIL combined with As(2)O(3) had synergistic effect in killing K562/AO2 and K562 cells by king's formula. The apoptosis rates of K562/AO2 and K562 cells were 34.93 +/- 0.10% and 10.53 +/- 0.16% (p < 0.01), as well as 5.95 +/- 0.07%, and 3.50 +/- 0.01% (p < 0.05), 50.95 +/- 0.91% and 20.75 +/- 0.95% (p < 0.05) respectively when their cells were treated by rmhTRAIL and As(2)O(3) alone. The apoptosis rate in K562/AO2 group was higher than that in K562 group. It is concluded that rmhTRAIL can induce K562/A02 and K562 cell apoptosis; rmhTRAIL combined As(2)O(3) had synergistic effects; the efficacy of on rmhTRAIL or As(2)O(3) inducing K562/AO2 cell apoptosis is higher than that on their parental cell line K562.
