OBJECTIVETo compare the therapeutic effect and toxicity of chemotherapy, used alone or in combined with Shenqi Fuzheng Injection (SFI), for the treatment of advanced colorectal carcinoma (ACRC).

METHODSOne hundred and fifty-two patients with ACRC were equally randomized by digital table, to the treated group, treated by chemotherapy of FOLFOX regimen combined with SFI, and the control group treated by FOLFOX regimen alone. The therapeutic effect and adverse reaction of the treatment in patients were assessed.

RESULTSThe effective rate (CR +PR) was 63.2% (48/76) in the treated group and 46.1% (35/76) in the control group, showing significant difference between the two groups (P < 0.05). The median survival time in the two groups was 31 weeks and 28 weeks respectively. CD4/CD8 ratio was significantly increased in the treated group (1.56 +/- 0.21, 1.64 +/- 0.28, P < 0.05), but significantly decreased in the control group (1.58 +/- 0.22, 1.46 +/- 0.33, P < 0.01). Quality of life in the former group was higher than that in the latter group (P < 0.05). Times/case of nausea, vomiting, leukopenia occurring in the control group was more than those in the treated group A (P < 0.05).

CONCLUSIONBy combining with SFI, some adverse reactions of chemotherapy (such as nausea, vomiting, leukopenia) and its influence on patients' immunity could be alleviated in treating ACRC, which might enhance the efficacy of chemotherapy, and improve the quality of life and prolong the median survival time in patients.

The purpose of the present study was to investigate whether the antipyretic effect of dexamethasone (DEX) delivered by intravenous injection (iv) on intracerebroventricularly (icv) administered egtazic acid-induced febrile response is relevant to the changes in cytosolic free calcium concentration of the hypothalamus. The colon temperatures were measured by a thermistor and the cytosolic free calcium concentration ([Ca2+]i) in dissociated brain cells was measured by Fura 2-AM. The results demonstrated that the pyretic action of egtazic acid (0.6 μmol, icv) was markedly inhibited by DEX (5 mg/kg,iv), but DEX (60～120 μmol/L) did′t affect [Ca2+]i in dissociated hypothalamus cells. Actinomycin D, which interferes with gene transcription (3 nmol, icv), completely abolished the antipyretic action of DEX on egtazic acid-induced fever. These findings suggest that the antipyretic action of DEX on egtazic acid-induced fever is related to the activation of certain gene expression in the brain,but not to the changes of transmembrane calcium ion current in hypothalamus neurons.

OBJECTIVETo evaluate the efficacy of nimotuzumab combined with palitaxel liposome and carboplatin (LP) regimen for treatment of advanced non-small cell lung cancer (NSCLC), and to observe the changes of tumor markers and toxicities in the treatment. METHODS Forty-one patients with advanced NSCLC were randomly divided into 2 groups: 21 patients in the observation group were treated with nimotuzumab (200 mg per week for 6 weeks), palitaxel liposome 160 mg/m2 and carboplatin (AUC = 6). 20 patients in the control group were given LP regimen. Each group completed two cycles of chemotherapy. The level of tumor markers (CEA, CYFR21-1 and NSE) and toxicities were checked at one week before and after the treatment. Thoracic CT examinations were taken before treatment and at the fourth week and eighth week after treatment.

RESULTSIn the observation group, there were 2 cases of CR, 7 cases of PR, 9 cases of SD and 3 cases of PD. The objective response rate (RR) was 42. 9% in the observation group. In the control group, there were 1 case of CR, 6 cases of PR, 8 cases of SD and 5 cases of PD, with a RR of 35.0% in this group. There was no significant difference in the RR between the two groups (P = 0.751). The time to progression (TIP) was 6. 9 months in the observation group and 5. 7 months in the control group, with a significant difference (P = 0.027). The levels of NSE decreased significantly in both groups and showed a significant difference (P = 0.039). The levels of CEA and CYFRA21 in both groups were decreased after treatment, but did not show a significant difference before and after treatment, respectively. Except 3 cases had I-II skin toxicities on the faces in the observation group, there was no significant difference in toxicities between the two groups.

CONCLUSIONNimotuzmab combined with LP regimen shows a synergistic effect, can increase the efficacy and prolong TFP in advanced NSCLC patients. The toxicities are mild and tolerable.

OBJECTIVETo detect changes of serum soluble Apo-1/Fas (sApo-1/Fas) in pancreatic cancer patients and to investigate its clinical value in assessing the effect of chemotherapy.

METHODSThe serum level of sApo-1/Fas in 30 normal control subjects and 58 pancreatic cancer patients were detected using enzyme-linked immunosorbent assay (ELISA), and the sApo-1/Fas level of 48 pancreatic cancer patients, before and after chemotherapy was compared.

RESULTSCompared with the level of the control group, the level of serum soluble Apo-1/Fas was significantly correlated with clinical stage but not with age, sex or pathologic type of pancreatic cancer. It was elevated gradually from stage II to IV (P < 0.01). However, it would obviously decrease in pancreatic cancer patients after chemotherapy (P < 0.01).

CONCLUSIONThe serum soluble Apo-1/Fas may be involved in the development of pancreatic cancer, and it may be used as one parameter to assess the disease status and prognosis of pancreatic cancer patient.

BACKGROUNDAlthough antiangiogenesis therapy plays an important role in anti-neoplastic treatment with its recognized efficacy and slight adverse effect, there is no prospective clinical trial to define ideal markers for predicting efficacy of antiangiogenic therapy. This study was undertaken to investigate the changes of activated circulating endothelial cells (aCECs) and survivin after anti-angiogenesis therapy and their significance in predicting the efficacy of the therapy.

METHODSPatients of non-small cell lung cancer (NSCLC) treated with chemotherapy with or without Endostar were observed. The amount of activated CECs was detected by flow cytometry, and the expression of survivin mRNA was determined by real-time polymerase chain reaction (PCR).

RESULTSAfter treatment, the amount of activated CECs decreased significantly in clinical benefit cases (P = 0.021 in chemotherapy alone, P = 0.001 in chemotherapy plus Endostar), increased in disease progressive cases (P = 0.015 in chemotherapy alone, but P = 0.293 in chemotherapy with Endotatar). After therapy, the expression of survivin mRNA decreased in clinical benefit cases (P = 0.001) and increased in disease progressive cases (P = 0.018). A positive correlation was found between activated CECs and survivin in the chemotherapy group pre- and post-therapy (P = 0.001 and 0.021, respectively), but only in the chemotherapy with Endostar group pre-therapy (P = 0.030) rather than post-therapy. A positive correlation was found between the decreased activated CECs after therapy and time to progression (TTP) (r = 0.322, P = 0.012); a negative correlation was found between the amount of survivin mRNA in serum post-therapy and TTP (r = -0.291, P = 0.048).

CONCLUSIONSActivated CECs and survivin may be ideal markers forecasting efficacy and prognosis of NSCLC. The former can reflect more sensitively antiangiogenic efficacy and the latter is more sensitive to shrinkage or swelling of tumors. Their combination can evaluate more accurately the efficacy of antiangiogenic therapy of NSCLC.

A fusion gene CTB-PROIN, in which Proinsulin gene was fused to the 3' end of CTB gene by a hinge peptide 'GPGP', was constructed and cloned into pET-30a(+) to obtain a prokaryotic expression vector pETCPI. Subsequently the recombinant plasmid pETCPI was transformed into E. coli stain BL21 (DE3). After induced by IPTG, the expression product was analyzed by sodium dodecyl sulphate-polyacrylamide gel (15%) electrophoresis (SDS-PAGE), and its result indicated that the recombinant protein CTB-PROIN was expressed and accumulated as inclusion bodies. The recombinant CTB-PROIN protein accumulated to the level of 25% of total bacterial proteins. After inclusion bodies was denaturalized and refolded in vitro, significant assembly of monomers had occurred, and the recombinant protein represented assembled pentamers. The results of western blotting analysis also demonstrated that the fusion protein could be recognized by the anti-CT and anti-insulin antibody, respectively. In addition, the result of the CTB-PROIN-GM1 binding assay, that the protein could bind to monosialoganglioside specifically, showed it possesed biological activity in vitro. These results provided the possibility of developing a cheaper and more efficient oral vaccine for type I diabetes using such constructs.

OBJECTIVETo determine the effects of cigarette smoking on the cyclogeny of spermatogenic cells in rats.

METHODSRat models of passive smoking were established using a self-made smoking device, and then allocated randomly into two passive smoking groups (A and B, n = 10) and two corresponding control groups (C and D, n = 10). Groups A and B were exposed to cigarette smoke for 8 weeks, followed by the sacrifice of the rats in Groups A and C. And the animals in Groups B and D were killed 48 days after the cessation of passive smoking. The spermatogenesis cycle of each group of rats was detected by flow cytometry, the levels of testosterone (T) and luteinizing hormone (LH) measured by radio-immunity method, and the testis histopathology analyzed by HE staining and transmission electron microscopy.

RESULTSCompared with Group C, Group A showed a significant decrease in the number of spermatids, spermatozoa ([18.76 +/- 3.58]%) and primary spermatocytes ([5.71 +/- 1.18]%) (P < 0.01), but an obvious increase in the spermatogonias ([55.98 +/- 5.35]%, P < 0.01), with a markedly decreased proliferation index ( P < 0.01). The rats of Group A also exhibited pycnosis of spermatocytes, nucleus aberration of Leydig cells, expansion and degranulation of the endoplasmic reticulum, decreased Golgi apparatus, increased lysosomes and fat drops of Sertoli cells, as well as a reduction in the thickness of the wall and the layers of seminiferous tubules and the number of spermatogonia. The T and LH levels were significantly lower in Group A than in C (P < 0.01). After the cessation of passive smoking, a remarkable increase was observed in the percentage of spermatozoa and primary spermatocytes and the levels of serum T and LH in Group B, although the latter were still lower than those of Group D.

CONCLUSIONSmoking damages spermatogenic epithelia, Leydig cells and Sertoli cells, reduces the T and LH levels, and block the proliferation of spermatogenetic cells. These changes can be partially reversed after cessation of smoking.
