Objective To investigate the clinical diagnostic and differential diagnostic values of antisense non-coding RNA in the INK4 locus (ANRIL) and tumor suppressors (p14ARF, p15INK4b and p16INK4a) mRNA expression levels in peripheral blood lymphocytes of patients with cirrhosis and hepatocellular carcinoma. Methods The patients with hepatocellular carcinoma and cirrhosis admitted in Shantou Central Hospital from October 2013 to April 2014 were selected. The real-time quantitative reverse transcription-polymerase chain reaction (RT-qPCR) was used to detect ANRIL, p14ARF, p15INK4b and p16INK4a mRNA expression levels of peripheral blood lymphocytes. The subjects having taken physical health examinations in outpatient clinics were assigned in the healthy control group. Results During the study period, 19 cases of hepatocellular carcinoma, 24 cases of cirrhosis, and 31 healthy controls were finally enrolled. In the hepatocellular carcinoma group, the mRNA expression level of ANRIL was significantly higher than that of the healthy control group (?Ct:13.07±0.62 vs. 12.45±0.84, P<0.01), while p15INK4b mRNA expression level was obviously lower than that of the healthy control group (13.24±0.98 vs. 13.99±0.99, P<0.05). But there were no significant differences in the mRNA expression levels of ANRIL (13.07±0.65 vs. 12.71±0.76) and p15INK4b (13.24±0.98 vs. 13.55±1.08) between the groups of hepatocellular carcinoma and cirrhosis (both P>0.05). There were also no statistically significant differences in p14ARF and p16INK4a mRNA expressions among the three groups (all P>0.05). Conclusion The elevation of ANRIL and descent of p15INK4b mRNA expression levels in peripheral blood lymphocytes in patients with liver lesion can be used as the reference indicators for the early diagnosis of hepatocellular carcinoma and to predict their prognoses.

Objective To Investigate correlation between screening assay of human papillomavirus (HPV) and microbial pathogens in gynecology. Methods Cervical samples were collected to search for HPV, bacteria and yeast infections in gynecologic outpatients. HPV typing was carried out by PCR and sequencing on cervical brush specimens. Chlamydia trachomatis was identified by strand displacement amplification (SDA) and the other microorganisms were detected by conventional methods. All data were analyzed to investigate the correlation among them. Results In this cross-sectional study, among 857 enrolled outpatients, there were 266 cases with positive HPV DNA, and the rate of infection was 31.0%(266/857). HPV genotype showed that thirty-five different HPV types were identified, of which HPV16 was the most prevalent ( 14.5%, 38/262), followed by HPV58 (9.2%, 24/262), HPV53 (8.0%, 21/262)and HPV42 (6.1%, 16/262); while other genotypes were present in less than 5% of HPV positive women.According to the reclassification, the aggregated percentage (high-risk and probably high-risk) of detected HPV was 58.8% ( 154/262), 27.9% (73/262) for low-risk and 13.4% (35/262) for unknown-risk HPV types. Among HPV positive women, cervical brush specimens results showed that more than 60% cases with normal cytology, 3.8% (10/266) with high-grade squamous intraepithelial lesions (HSIL), 29. 7% (79/266) with low-grade squamous intraepithelial lesions (LSIL) and 3.0% (8/266) with atypical squamous cells of undetermined significance (ASCUS), respectively. Statistical analyses revealed there was a significant association between the infected HPV and Chlamydia trachomatis or Ureaplasma urealyticum ( >10000 CCU/ml; all P <0.01), while no correlation was found between HPV infection and bacterial vaginosis, streptococcus agalactiae, candida, Trichomonas vaginalis or Ureaplasma urealyticum ( ≤ 10000CCU/ml; all P > 0.05 ). Among the cases with bacterial vaginosis, the positive rate of HPV infected was42.6%. Chlamydia trachomatis was one of the high-risk factors for the infection of HPV ( OR = 2.82, 95%CI: 1.74 -4.57). Mycoplasma hominis was isolated only in 2 cases, no patient was infected with Neisseria gonorrhocae. Conclusions Although bacterial vaginosis was not significantly associated with HPV, it was more common among the HPV positive women. There is the significant association between HPV and Chlamydia trachomatis or Ureaplasma urealyticum which may be increase the infection of HPV. These data suggest that it may be important to screen for the simultaneous presence of different microorganisms which may have synergistic pathological effects.

BACKGROUND: Our previous studies have demonstrated that cryopreserved bone marrow stromal cells (BMSCs) still maintain high survival rate, cell proliferation and osteogenic differentiation potentials after thawing. However, this result needs confirmed in vivo environment. OBJECTIVE: To explore the effects of cryopreserved BMSCs and collagenic membrane BME-10X complex on type Ⅰ collagen synthesis in vivo. METHODS: Beagle dog BMSCs were cultured in vitro and cryopreserved for 12 months, which were thawed and prepared complexes with collagenic membrane. The complexes were cultured with mineralization induction medium or normal medium for 5 days, followed by implanting into nude mice. The specimens were harvested and analyzed by gross observation, histopathological and immunohistochemistry at 4 weeks after implantation. The collagenic membrane cultured with mineralization induction medium served as controls. RESULTS AND CONCLUSION: In the control group, the boundary of collagenic membrane was distinctly, without cell growth around boundary or intra collagenic membrane, additionally, there was little type Ⅰ collagen. In the non-induction group, cells grew into collagenic membrane, trabes-like collagen formed, and type Ⅰ collagen distribution increased at 4 weeks. In the induction group, scaffold degraded, more cells grew, and plenty of collagen formed osteoid-like tissues. The distribution of typeⅠcollagen was obviously increased than that of other groups. The findings demonstrated that cryopreserved BMSCs possess strong osteogenic differentiation potentials after proliferation and induction combined with collagenic membranes in vitro.

BACKGROUND:So far the positive or negative effects of mesenchymal stem cel s on tumor growth and metastasis are under discussion. OBJECTIVE:To explore the mechanism of bone marrow mesenchymal cel s in promoting lung cancer metastasis. METHODS:Primary rat bone marrow mesenchymal stem cel s were obtained by direct adherence method of the whole bone marrow, and differential adherence combined with digestion control method was performed to purify cel s. Lung cancer cel lines were cultured, and the effects of bone marrow mesenchymal stem cel s on the migration, invasion and metastasis of lung cancer cel s were observed by scratch test, cel invasion and migration assays. Orthotopic lung cancer models were established in rats and bone marrow mesenchymal stem cel s were seeded onto the left lung of rats. Then, pathological changes of lung tissues were observed at 14 days after transplannation. RESULTS AND CONCLUSION:After the scratch test, the migration rate of lung cancer cel s became higher, and the scratches healed with time. And after cel transplantation, the number of migrated lung cancer cel s increased, as wel as the ability of lung cancer cel s penetrating the Matrigel was strengthened. Besides, fibrous connective tissues could be found around the lung cancer tissues, and necrosis with distinct boundary and large tumor nuclei;the metastatic tissues showed obvious infiltration and necrosis with large tumor nuclei. These results suggest that bone marrow mesenchymal stem cel s can promote the invasion, migration and metastasis of lung cancer cel lines.
