4. The association between a genetic variant in MKK4 gene promoter and lung cancer risk in Southern Chinese population
Tumor 2011;31(12):1082-1086
Objective: To investigate the association between the single nucleotide polymorphism (SNP) of mitogen-activated protein kinase kinase 4 (MKK 4) promoter and the risk of lung cancer development in Southern Chinese population. Methods: A hospital-based case-control study including 800 cases of lung cancer and 900 healthy controls was conducted. TaqMan assay was used to test the SNP of rs3826392 (-1304T>G) in MKK 4 promoter, and the software SAS 9.13 was used to analyze the association of MKK4 polymorphism and the susceptibility of lung cancer. Results: The observed genotype frequency of -1304T>G in MKK4 promoter was appropriate for Hardy-Weinberg equilibrium in the healthy controls (P = 0.149). The distribution of genotypes was significantly different between the cases of lung cancer and the healthy controls (P=0.001). Compared with homozygous genotype (TT), the risk for lung cancer was decreased by 25% in the carriers of heterozygous genotype (TG) [adjusted odd ratio (OR ) = 0.75, 95% confidence interval (CI) = 0.58-0.97)], and the risk for lung cancer in carriers of GG homozygote was decreased by 45% (adjusted OR = 0.55, 95% CI = 0.33-0.94). There was a significantly decreased trend in the risk for lung cancer along with the increased number of mutation-typic G allele (Ptrend<0. 001). Conclusion: These findings demonstrate that -1304T>G genotype in promoter region of MKK4 gene may contribute to the decreased risk of lung cancer. Copyright© 2011 by TUMOR.

Objective:
To investigate HIV-1 subtypes and drug resistance in HIV/AIDS patients who failed in antiretroviral therapy in Jinhua City, Zhejiang Province, so as to provide the basis for improving antiretroviral therapy strategy.
Methods:
Totally 128 plasma samples of HIV/AIDS patients who failed in antiretroviral therapy (treatment for more than 6 months and viral load ≥1 000 copies/mL) from January 1 to November 30, 2023 were collected. After nucleic acid extraction and amplification, the sequences of HIV-1 pol genes were determined using first generation sequencing method, then submitted to HIV resistance database of Stanford University in the United States, and the subtypes, drug resistance mutations and drug resistance status of HIV-1 were analyzed.
Results:
A total of 118 sequences of HIV/AIDS patients were obtained, including 94 males and 24 females (male to female ratio, 3.9︰1). There were 53 cases aged between 40 to 59 years, accounting for 44.92%. The main infection routes was heterosexual contact, with 92 cases accounting for 77.97%. The main HIV-1 gene subtypes were CRF07_BC and CRF01_AE, with 45 and 39 cases accounting for 38.14% and 33.05%, respectively. There were 75 cases found to have drug-resistant site mutations, with a mutation rate of 63.56%. The most common mutation sites were M184 and K103, with mutation rates of 29.66% and 28.81%, respectively. There were 58 cases with resistance to more than one drug, with a rate of 49.15%. The rates of resistance to non-nucleoside reverse transcriptase inhibitors (NNRTI), nucleotide reverse transcriptase inhibitors (NRTI) and protease inhibitors (PI) were 50.00%, 33.90% and 4.24%, respectively.
Conclusion
The HIV-1 gene subtypes of HIV/AIDS patients who failed in antiretroviral therapy in Jinhua City are mainly CRF07_BC and CRF01_AE, which are mainly resistant to NNRTI and NRTI.

The nafion/carbon nanoparticles (CNPs) composite film modified glassy carbon electrode was pre pared by dropwise method, and the electrocatalyst of H_2O_2 at Nafion/CNPs modified electrode was investiga ted.The results show that electrocataytic activitie for detection of H_2O_2 at the modified electrode is very good.The biosensing application of CNPs was demonstrated through fabrication of an electrochemical biosensor.The biosensor was constructed by encapsulating glucose oxidase in the Nafion/CNPs composite film.The biosensor had good electrocatalytic activity toward oxidation of glucose.The glucose biosensor shows a linear range from 2.0 × 10 ~(-6) to 6.0×10~(-3) mol/L with a detection limit of 1.6×10 ~(-6) mol/L.The biosensor shows high stabili ty, good reproducibility and can avoid the commonly coexisted interference.In addition, real rat serum samples were analyzed by this biosensor with satisfactory results.

Objective To observe the effeet of cotransduction of wt-p53,B7-1 and GM-CSF genes mediated by recombinant adenovirus on cell growth, apoptosis and immunogenicity of neuroblastoma cell line SH-SY5Y, Methods We transfected SH-SYSY cells separately with recombinant adenovirus, recombinant adenovirus mediating human wild type p53(wt-p53) gene and BB-102.We separately named them with SH/Ad,SH/p53 and SH/BB-102 group.The protein expression of p53, B7-1 and GM-CSF were measured by Western blot, FCM and enzyme linked immunosorbent assay. Cell number was counted and growth curves were drawed. Cell apoptosis was tested by FCM. Lymphocyte proliferation and cytokine secretory was evaluated by mixed lymphocyte culturing. Results After transection with BB- 102, p53, B7-1, and GM-CSF, high-efficiency expression of target genes were found. Growth of the cells was inhibited, apoptosis was induced in the SH/p53 and SH/BB-102 groups. Proliferation of lymphocytes was stimulated and cytokine increased visorously in the SH/BB-102 group. Condusions After transfection with BB-102, growth of the SH-SY5Y cells was inhibited,apoptosis was induced,and immunogenicity was greatly enhanced.

Objective To explore effective methods of diagnosis and treatment for delayed rupture of the spleen (DRS) through retrospective analysis of 32 cases. Methods A retrospective study was done in 32 cases with DRS. The effects of CT, ultrasound and diagnostic peritoneal lavage on diagnosis of DRS was observed and compared. Results Splenectomy was performed in 26 cases, among which one died four days after splenectomy because of complicated brain injury and six given conservative treatment under continuous monitoring discharged. The mean hospitalization duration was 18.5 days. Conclusions Diagnostic peritoneal lavage can improve the positive rate of peritoneal puncture. Ultrasound is an important method for diagnosing DRS and closely monitoring the patients receiving conservative treatment.

Purpose:To study the changes of t-PA ?u-PA expression and fibrinolysis molecular mark ers in patients with gastric or intestinal cancer in order to elucidate their cl inical significance. Methods:The plasma levels of t-PA ?u-PA ?u-PAR and PAP were measured by ELISA . Gen e transcription of t-PA?u-PA mRNA were detected by Real-time RT-PCR. Results:The plasma levels of u-PA?u-PAR and PAP were elevated in gastric or intestina l cancer patients ,while u-PA was markedly elevated in patients with local infi ltration?lymph node involvement or distal metastasis. u-PA mRNA was higher and t-PA was lower in gastric or intestinal cancer compared to normal tissue. Conclusions:Hyperfibrinolysis was an important factor related with m etastasis potential of gastric or intestinal cancer. t-PA may be a character of well differentiated tissue.
