Objective: To investigate the expression and clinical significance of LMTK3 in patients with prostate carcer. Methods: Immunohistochemistry was used to detect the expression of LMTK3 and ERα in 55 cases of prostate cancer tissues and 25 cases of benign prostatic hyperplasia tissues. The relationship between the expression of LMTK3 and ERα and clinicopathological parameters was evaluated by square test and Fisher exact test. The association between LMTK3 and ERα expression was analyzed with Pearson and Spearman rank correlation. Results: The results of immunohistochemistry demonstrated that the LMTK3 and ERα protein positive expression rate in 55 cases of prostate cancer tissues was 36. 36% and 32. 73%, whereas was 64. 00% and 56. 00% in the benign prostatic hyperplasia, respectively, showed a significant difference of comparison within this result ( P < 0. 05). The expression of LMTK3 in prostate cancer tissues was inversely related with the level of Gleason grade ( P<0. 05), but no relation with the levels of age, TPSA, TNM stage and lymph node metastasis ( P>0. 05). Moreover, the expression of ERα in prostate cancer tissues was oppositely related with the levels of gleason grade and TPSA ( P<0. 05), but no relation with the levels of age, TNM stage and lymph node metastasis ( P>0. 05). Pearson and Spearman rank correlation analysis revealed, to some extent, there was positively correlated with the two proteins ( r = 0. 296, P<0. 05). Conclusion: The expression of LMTK3 in prostate cancer tissues was decreased compared with benign prostatic hyperplasia tissues and negatively related with the level of gleason grade. In some degree, there is a positively correlation between the LMTK3 and ERα proteins.

[Objective]To investigate the safety and efficacy of phosphorylcholine oligomer grafted graphene oxide as a drug carrier for transcatheter arterial chemoembolization in the treatment of liver cancer.[Methods]Doxorubicin loaded folic acid labeled phosphorylcholine oligomer grafted graphene oxide(DOX@GO-PCn-FA)was prepared. Graphene ox-ide(GO)and DOX@GO-PCn-FA were injected intravenously via marginal ear vein in New Zealand white rabbits respec-tively to assess their safety and biodistribution for intravenous administration.Ten male New Zealand rabbits were used to establishe the VX2 liver cancer model and the tumor characteristics were confirmed by dynamic contrast enhanced CT scan.Catheter was inserted via femoral artery and advanced into hepatic lobar or segmental artery.Digital subtraction angi-ography(DSA)was performed to validate the tumor feeding vessels.DOX@GO-PCn-FA was injected through the cathe-ter to carry out selective transcatheter arterial chemoembolization(TACE). Dynamic enhanced CT scan and pathological examinations of major tissues and organs were implemented 7 days post TACE to evaluate the efficacy of embolization effect of DOX@GO-PCn-FA against liver tumor as well as the biodistribution and safety.[Results]Intravenous injection of GO resulted in significant thrombosis and pulmonary embolism whereas DOX@GO-PCn-FA of same dosage did not. DOX@GO-PCn-FA was capable of effectively diminishing the blood supply of liver tumors when applied in TACE. Pathologic exploration revealed that DOX@ GO-PCn-FA mainly deposited in the tumor,and no obvious complications were observed.[Conclusions]GO-PCn presented superior biocompatibility and exerted effective chemoembolization against liver cancer.

This study was purposed to investigate the incidence of mixed lineage leukemia (MLL) gene rearrangement and partner gene types as well as the clinical features and prognosis of acute leukemia (AL) with this rearrangement through detection in adult AL using combination of 3 techniques, and to evaluate the clinical value of this combination detection. The MLL gene rearrangement in 183 cases of adult AL was detected by combination of conventional cytogenetics, split signal FISH and multiplex nested PCR. The results showed that the incidence of MLL rearrangements in adult patients with AL was low (8.2%), and MLL-AF4 fusion gene was most common and predominant in acute lymphoblastic leukemia (ALL), while the MLL-AF6 and MLL-AF9 were most frequent in acute myeloid leukemia (AML). Extramedullary involvements were found in 40% of MLL-rearranged AL patients, and 33.3% of patients with MLL-rearranged AL reached to complete remission within 30 days during induction chemotherapy. In addition, in this cohort of MLL-rearranged adult AL patients, the 3-month relapse rate and 6-month overall survival rate were 50.0% and 50.0% respectively. It is concluded that the rate of missed diagnosis of CC technique for patients with MLL-rearranged AL reached to 60% in this study, while the combination of CC, FISH and multiplex nested PCR has been confirmed to have important significance for evaluating prognosis and conducting clinical therapy of patients with MLL-rearranged AL.

The aim of this study was to explore the clinical effect and complications of allogeneic peripheral blood stem cell transplantation (allo-PBSCT) in hematologic malignancies through retrospective analysis of 75 patients (42 male, 33 female; aged from 13 to 72 years old) received allo-PBSCT from HLA matched (n=61) or haploidentical donors (n=14). 75 patients included 35 patients with chronic myeloid leukemia (CML), 30 patients with acute myeloid leukemia, 5 patients with severe aplastic anemia, 3 patients with acute lymphocytic leukemia, one patients with multiple myeloma and one patients with paroxysmal nocturnal hemoglobinuria. Conditioning regimens were (1) Cy/TBI or Bu/Cy; (2) Cy/TBI+Ara-C; (3) fludarabine+TBI/or (CTX+ATG). Minimal residual disease has been monitored regularly by PCR and FISH. Patients received cyclosporine A and methotrexate or ATG and anti-CD25 monoclonal antibody and mycophenolate mofetil for graft-versus-host disease (GVHD) prophylaxis. Relapsing patients after transplantation received DLI and/or chemotherapy. Patient with CML were treated with imatinib. The results showed that 74 patients had hematopoietic reconstitution, and eventually converted to full donor chimerism by FISH or PCR-STR. The median time for the initial hematopoietic reconstitution was 15 (5-25) days. 46 out of 75 patients were alive and median duration was 23 (2-61) months. Among 29 dead patients, 9 died of disease relapse, 7 died of III-IV grade of acute GVHD and 7 died of severe infection (2 patients developed interstitial pneumonia). 9 out of 14 patients received haploidentical transplantation were alive, and the time of event-free survival was 30 (6-53) months, the mean survival time of 5 died patients was 7 (2-17) months. 16 patients were infected by cytomegalovirus, 2 of them died of interstitial pneumonia. None of them suffered from veno-occlusive disease in the liver. It is concluded that allo-PBSCT is effective to treat refractory hematologic diseases, and DLI/or chemotherapy should be used in the patients relapsing after transplantation.

To investigate the effects of Corydalis Rhizoma and L-tetrahydropalma-tine (L-THP) on the levels of dopamine neurotransmitter (DA), dopamine transporter (DAT) and the second dopamine receptor (D2R) in learning and memory-related brain areas, hippocampus and striatum, the DA, DAT and D2R were detected in conditioned place preference (CPP) rats suffered from morphine. And comparation the degree of similarity and consistency of the pharmacological effects was also studied. The rats were trained in black compartments and white ones (drug-paired compartment) with the increasing doses of morphine for 10 days (hypodermically injected from 10 mg•kg⁻¹ to 100 mg•kg⁻¹). Models of CPP were validated in those psychological dependence rats after 48 h training. The dopamine contents were detected as soon as the materials of hippocampus and striatum are harvested from rats of NS control group and model group. The DAT and D2R levels are measured by Western blot. The high, medium and low dose group of Corydalis Rhizoma are given Corydalis Rhizoma 2, 1, 0.5 g•kg⁻¹ water extraction liquid respectively (which contains L-THP were 0.274, 0.137 and 0.137 mg respectively), and the high, medium and low dose group of L-THP were given L-THP 3.76, 1.88, 0.94 mg•kg⁻¹ lavage treatment respectively, NS treatment group were lavaged normal saline for 6 days and they were killed after test of CPP, again tested DA levels and expression of DAT and D2R similar to the front of materials. The reduction effects of CPP were observed in the groups of both Corydalis Rhizoma (2, 1 g•kg⁻¹) and L-THP (3.76, 1.88 mg•kg⁻¹) subjected to medicine for 6 days (P<0.01). Compared with the NS treatment group and the model group, the higher values including in the contents of neurotransmitter dopamine were detected of hippocampus and striatum (P<0.01, P<0.05), the DAT and D2R protein expression of Corydalis Rhizoma (2, 1 g•kg⁻¹) and L-THP (3.76, 1.88 mg•kg⁻¹) increased in hippocampus and striatum (P<0.01). Learning and memory-related brain regions hippocampus and striatum was another neuroanatomical sites of action in the treatment of mental dependence of fumarate and L-THP, its mechanism was related to lowering its elevated DA neurotransmitter levels, and increasing the expression of DAT and D2R. Corydalis Rhizoma could be play 14-times roles in effect of L-THP. The similar effects were observed on the neurotransmitter dopamine, DAT and D2R in learning and memory-related brain areas, hippocampus and striatum of the morphine- dependent rats.

Objective: To summarize the clinical data and prognosis of children with Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) common genes. Methods: This was a retrospective cohort study.Clinical data of 56 children with Ph-like ALL common gene cases (Ph-like ALL positive group) treated from January 2017 to January 2022 in the First Affiliated Hospital of Zhengzhou University, Henan Children's Hospital, Henan Cancer's Hospital and Henan Provincial People's Hospital were collected, 69 children with other high-risk B cell acute lymphoblastic leukemia (B-ALL) at the same time and the same age were selected as the negative group. The clinical characteristics and prognosis of two groups were analyzed retrospectively. Comparisons between groups were performed using Mann-Whitney U test and χ2 test. Kaplan-Meier method was used for survival curve, Log-Rank test was used for univariate analysis, and the Cox regression model was used for multivariate prognosis analysis. Results: Among 56 Ph-like ALL positive patients, there were 30 males and 26 females, and 15 cases were over 10 years old. There were 69 patients in Ph-like ALL negative group. Compared with the negative group, the children in positive group were older (6.4 (4.2, 11.2) vs. 4.7 (2.8, 8.4) years), and hyperleukocytosis (≥50×109/L) was more common (25% (14/56) vs. 9% (6/69)), the differences were statistically significant (both P<0.05). In the Ph-like ALL positive group, 32 cases were positive for IK6 (1 case was co-expressed with IK6 and EBF1-PDGFRB), 24 cases were IK6-negative, of which 9 cases were CRLF2 positive (including 2 cases with P2RY8-CRLF2, 7 cases with CRLF2 high expression), 5 cases were PDGFRB rearrangement, 4 cases were ABL1 rearrangement, 4 cases were JAK2 rearrangement, 1 case was ABL2 rearrangement and 1 case was EPOR rearrangement. The follow-up time of Ph-like ALL positive group was 22 (12, 40) months, and 32 (20, 45) months for negative group. The 3-year overall survival (OS) rate of positive group was significantly lower than the negative group ((72±7) % vs. (86±5) %, χ2=4.59, P<0.05). Compared with the 24 IK6-negative patients, the 3-year event free survival (EFS) rate of 32 IK6 positive patients was higher, the difference was statistically significant ((88±9) % vs. (65±14) %, χ2=5.37, P<0.05). Multivariate Cox regression analysis showed that the bone marrow minimal residual disease (MRD) not turning negative at the end of first induction (HR=4.12, 95%CI 1.13-15.03) independent prognostic risk factor for patient with Ph-like ALL common genes. Conclusions: Children with Ph-like ALL common genes were older than other high-risk B-ALL patients at diagnosis, with high white blood cells and lower survival rate. The bone marrow MRD not turning negative at the end of first induction were independent prognostic risk factor for children with Ph-like ALL common gene.

OBJECTIVETo study and compare the effect of Corydalis yanhusuo and L-THP on dopamine neurotransmitter and D2 receptor of reward circuitry in various cerebral areas of conditioned place preference model rats and the comparison of their effects.
METHODThe CPP model was established by injecting morphine in rats with increasing doses for 10 days. The initial dose of 10 mg x kg(-1), and the final dose of 100 mg x kg(-1), with 10 mg x kg(-1) increased each day. At 48 h after the final training, CPP was adopted to detect the successful establishment of the model. On the same day (12 d), they were orally administered with 2, 1, 0.5 g x kg(-1) C. yanhusuo (containing 0.153, 0.077 and 0.038 mg L-THP) and L-THP (3.76, 1.88, 0.94 mg x kg(-1)) for six days. On 18 d, CPP test was performed again. Next day, HPLC was adopted to determine the content of dopamine neurotransmitters of reward circuitry in VTA-NAc-PFC; Immunohistochemistry and Western blotting were adopted to detect the expression of D2 receptors.
RESULTCompared with the physiological saline treatment group, C. yanhusuo (2, 1 g x kg(-1)) and L-THP (3.76, 1.88 mg x kg(-1)) groups showed that rats stayed in a notably shorter period in white boxes (morphine-accompanied boxes) (P < 0.01 or P < 0.05), and revealed a remarkably lower dopamine content in VTA, NAc and PFC and the significant increase in the expression of D2 receptor (P < 0.01 or P < 0.05).
CONCLUSIONThe down-regulation of the increased dopamine content in reward nervous circuitry and the up-regulation of the expression of D2 receptor may be one of mechanisms of C. yanhusuo and L-THP in accelerating the recession of morphine's CPP effect Regarding the inhibition of morphine's CPP effect and the effect on dopamine system, the effect of C. yanhusuo traditional Chinese medicine containing one-fold L-THP monomer is equal to that of the independent application of around 24-fold L-THP monomer.

This study was designed to establish a multiplex allele-specific polymerase chain reaction method for simultaneous identification of Dendrobium huoshanense, D. officinale and D. devonianum, which may resolve identification problems of caulis dendrobii. Internal transcribed spacer sequences and trnL-trnF sequences of the Dendrobium species were aligned by BioEdit software, then specific SNPs of the three species were analyzed for designing allele-specific primers and the multiplex allele-specific PCR reaction system was established. The different origin of Dendrobium huoshanense, D. officinale and D. devonianum was amplified and identified by the sizes of respective band. The results showed that 584 bp, 397 bp and 211 bp bands could be amplified by D. devonianum, Dendrobium officinale and Dendrobium huoshanense respectively, when the annealing temperature was 61 ℃ and the number of cycles was 35. The limit of detection (LOD) of D. devonianum and D. huoshanense were both 1.2 ng, while D. officinale was low than 0.24 ng. The detection limit of adulterates in D. devonianum, D. devonianum and D. huoshanense mixture sample was 1%, 1% and 5% respectively. This result suggests that the method of multiplex allele-specific PCR is useful to identify D. huoshanense, D. officinale and D. devonianum is accurate and specific.

BackgroundFunctional dyspepsia (FD) is a common upper gastrointestinal disorder worldwide, but the current treatments for FD are still unsatisfactory. The aims of this study were to investigate the efficacy and safety of Qi-Zhi-Wei-Tong granules in patients with postprandial distress syndrome (PDS)-predominant FD.
MethodsThe study was conducted as a randomized, double-blinded, multicenter, placebo-controlled design in 197 patients with PDS. All participants received placebo treatment for 1 week. Patients whose total symptom score decreased by <50% after the placebo treatment were recruited into the 4-week treatment period, in which they were randomly assigned to be treated with either Qi-Zhi-Wei-Tong granules or placebo. The patients were then followed for 2 weeks without any treatment. Dyspeptic symptoms were scored at weeks 2 and 4 during the random treatment period and 2 weeks after the treatment. Anxiety and depression symptoms were also scored and compared.
Results(1) The total effective rates in the Qi-Zhi-Wei-Tong granules group at weeks 2 and 4 during the random treatment period and 2 weeks after treatment were all significantly higher than those in the placebo group (38.82% vs. 8.75%, P < 0.001; 69.14% vs. 16.25%, P < 0.001; 77.65% vs. 21.25%, P < 0.001). (2) The total dyspeptic symptoms scores in the Qi-Zhi-Wei-Tong granules group at weeks 2 and 4 and 2 weeks after treatment were significantly lower than those in the placebo group. (3) The severity and frequency of each dyspeptic symptom at weeks 2 and 4 and the follow-up period were all significantly lower than those in the placebo group. (4) The anxiety scores in the Qi-Zhi-Wei-Tong granules group were significantly lower than those in the placebo group. (5) Qi-Zhi-Wei-Tong granules did not have more adverse effects than the placebo.
ConclusionQi-Zhi-Wei-Tong granules offer significant symptomatic improvement in PDS with no more adverse effects than placebo.
