Objective To study the inhibitory effects of wild-type p53 on gastric cancer cell lines BGC-7901 and to explore the importance of wild-type p53 in gene therapy for gastric cancer. Methods Adenoviral vector with exogenous wild-type p53 gene was transfected into the gastric cancer cell line BGC-7901 which harbours a mutation in codon 204 of the p53 gene.The transfer efficiency and expression effect of p53 were examined by immunohistochemistry and in situ hybridization. The growth of BGC-7901 cells in vitro was determined by cell counting and MTT assay. Flow cytometric analysis was used for observing cell cycle.Results Transfer efficiency reached 100% in BGC-7901 cells when adenovirus infection ability was over 100MOI. 3 days after transfection, the introduction of exogenous wild-type p53 into the tumor cells resulted in decreased expression of the protein of mutant p53 and increased level of mRNA of wild-type p53 gene. The growth of the BGC-7901 cells was significantly slower after transfection with wild-type p53 gene than that before transfection. The percentage of G 1/G 0 phase of the cells with exogenous wild-type p53 gene was much higher than that of the cells without exogenous wild-type p53 gene.It was 56 47% and 79 40% respectively(P

OBJECTIVETo observe the clinical efficacy on constipation predominant irritable bowel syndrome (IBS-C) treated with acupuncture for regulating the mind and strengthening the spleen and the impacts on the quality of life in the patients.
METHODSSixty patients of IBS-C were randomized into two groups. In the acupuncture group (30 cases), acupuncture was applied to Tianshu (ST 25), Zusanli (ST 36), Shangjuxu (ST 37), Taichong (LR 3), Sanyinjiao (SP 6), Yintang (GV 29) and Baihui (GV 20), once a day, 5 treatments a week and 4 weeks treatment as one session. In the western medication group (30 cases), lactulose oral solution was prescribed, 15 mL each time, three times a day, 4 weeks treatment as one session. The symptom grade scale and the quality of life scale (IBS-QOL) were adopted to observe the changes in clinical symptoms and quality of life before treatment, after treatment and 2-month follow-up after treatment in the patients of the two groups separately.
RESULTS(1) Clinical symptom score: the difference in the symptom score at each time point was significant statistically in intra-group comparison (P < 0.01). In 1 week, 4 weeks of treatment and 2 months after treatment, the clinical symptom scores in the acupuncture group were lower than those in the western medication group (P < 0.05, P < 0.01). (2) IBS-QOL score after treatment was improved as compared with that before treatment in the two groups (P < 0.01). The improvement of IBS-QOL at 2 months after treatment in the acupuncture group was apparently superior to the western medication group (P < 0.05). (3) The total effective rate was 90.0% (27/30) in the acupuncture group and was 83.3% (25/30) in the western medication group. The overall efficacy in the acupuncture group was better than that in the western medication group (P < 0.01).
CONCLUSIONAcupuncture for regulating the mind and strengthening the spleen significantly relieves the clinical symptoms of IBS-C and improves QOL of patients. The total efficacy is superior to lactulose oral solution and presents a certain of long-term efficacy.

Objective To explore whether MiR-129-5p participates in radiosensitivity of medullary thyroid cell MZ-CRC-1 by inhibiting the gene expression of high mobility group protein B1 ( HMGB1) . Methods The radioresistant cell line MZ-CRC-1/R was established from MZ-CRC-1. Cell survival fraction was analyzed by colony formation assay. The expressions of miR-129-5p in MZ-CRC-1 and MZ-CRC-1/R cells were detected by qRT-PCR. Cell viability was determined by MTT assay. Cell apoptosis was measured by flow cytometry. Dual-luciferase reporter assay was performed to confirm the relationship between miR-129-5p and HMGB1. Besides, the protein expressions of HMGB1 and p-AKt were evaluated by western blot. Results Compared with that of MZ-CRC-1 cells, the survival fraction of MZ-CRC-1/R cells was significantly increased (t=3. 038, 4. 330, 4. 885, 4. 568, P<0. 05), the cell viability of MZ-CRC-1/R cells was also increased ( t=3. 637, 7. 734, 11. 896, 14. 522, P<0. 05) , and the expression of miR-129-5p(0.26±0.03) was significantly decreased in MZ-CRC-1/R cells(1.00±0.06) (t=19. 107, P<0. 05) . Compared with miR-NC-inhibitor group, cell viability was promoted and cell apoptosis was blocked in the miR-129-5p-inhibitor group ( t=5. 156, 6. 005, 9. 649, 8. 659, P<0. 05) . Moreover, miR-129-5p mimic suppressed cell viability and enhanced cell apoptosis after irradiation ( t=3. 118, 5. 034, 6. 005, 7. 488, 6. 362, P<0. 05) . Overexpression of miR-129-5p inhibited the protein expressions of HMGB1 and p-AKt (t=9. 325, 10. 614, P<0. 05). In addition, HMGB1 depletion rescued cell apoptosis that was reduced by miR-129-5p inhibitor in MZ-CRC-1 cells ( t=6. 700, P<0. 05) , while HMGB1 overexpression attenuated the effect of miR-129-5p upregulation on MZ-CRC-1/R cells ( t=7. 073,P<0. 05) . Conclusions miR-129-5p increased the radiosensitivity of medullary thyroid-like cell MZ-CRC-1 by inhibiting HMGB1.

Similar to blood,interstitial fluid(ISF)contains exogenous drugs and biomarkers and may therefore substitute blood in drug analysis.However,current ISF extraction techniques require bulky instruments and are both time-consuming and complicated,which has inspired the development of viable alterna-tives such as those relying on skin or tissue puncturing with microneedles.Currently,microneedles are widely employed for transdermal drug delivery and have been successfully used for ISF extraction by different mechanisms to facilitate subsequent analysis.The integration of microneedles with sensors enables in situ ISF analysis and specific compound monitoring,while the integration of monitoring and delivery functions in wearable devices allows real-time dose modification.Herein,we review the progress in drug analysis based on microneedle-assisted ISF extraction and discuss the related future opportunities and challenges.

Objective:To explore the diagnostic efficacy difference and clinical diagnostic value of chronic lymphocytic leukemia flow (CLLflow) score and Moreau score (MS) in the diagnosis of chronic lymphocytic leukemia (CLL).Methods:According to the latest international and national diagnosis criteria for CLL, 133 patients with B-cell chronic lymphoproliferative diseases and uncertain immunophenotypes (B-CLPD), diagnosed by Zhengzhou Jinyu Comprehensive Haematological Pathology Diagnosis Centre from March 2020 to May 2021, were included in this study. Above patients were divided into the CLL group ( n=83) and non-CLL group ( n=50). The expression of clusters of differentiation (CD)5, CD10, CD20, CD19, κ light chain, λ light chain, FMC7, CD23, CD22, surface immunoglobulin M, CD200 and CD79 were detected by flow cytometry, and CLLflow score and MS score were calculated respectively according to the scoring rules. A fourfold table was used to compare the diagnostic efficacy of the two scoring systems, and the Kappa test and McNemar test were used to compare the consistency and superiority of the systems. Results:The rate of negative and positive CLLflow score were 4.8% (4/83) and 95.2% (79/83) in the CLL group and were 80.0% (40/50) and 20.0% (10/50) in the non-CLL group, and respectively (both P<0.001). The MS score (≤2, =3 and≥4) was 1.2% (1/83), 10.8% (9/83) and 88.0% (73/83) in the CLL group and was 86.0% (43/50), 14.0% (7/50) and 0 in the non-CLL group, there were significant statistical difference between the two groups ( P<0.001). The sensitivity, specificity, positive predictive value and negative predictive value of the CLLflow score were 95.2% (79/83), 80.0% (40/50), 88.8% (79/89) and 90.9% (40/44), respectively and those of MS score were 98.8% (82/83), 86.0% (43/50), 92.1% (82/89) and 97.7% (43/44) respectively. The overall coincidence rate, positive and negative coincidence rate between the CLLflow score and MS score were 91.0% (121/133), 93.3% (83/89) and 86.4% (38/44) respectively. Besides, the McNeamr dominance test presented no significant difference ( P>0.05) and high consistency (Kappa=0.796) between the two scoring systems. With MS≤2 and MS≥4, the sensitivity and the specificity of the MS score were 100% (73/73) and 97.7% (43/44) respectively, and for the CLLflow score, the sensitivity and the specificity were 97.3% (71/73) and 86.4% (38/44) in this MS range. With MS = 3, the sensitivity and specificity of the MS score were 100% (9/9) and 0 (0/7), and CLLflow was 88.9% (8/9) and 57.1% (4/7). Conclusions:The diagnostic efficacy is similar and presents high consistency between the CLLflow score and MS score in CLL diagnosis. For CLL patients with MS = 3, the specificity of MS is relatively low, combined assessment with CLLflow score could improve the diagnosis efficacy for CLL in these patients.
