Objective To compare the impact on the ovarian reserve function after cisplatin intraperitoneal or intravenous chemotherapy in rats model. Methods Thirty 8-weeks old female Sprague Dawley rats were randomly assigned to control group (group A, n=10), intraperitoneal chemotherapy group (group B, n=10) and intravenous chemotherapy group (group C, n=10). Cisplatin was diluted by normal saline (NS) into 4 mg/ml. On the first day of chemotherapy, 0.2 ml cisplatin dilution was injected into the abdomen of rats in group B, isodose cisplatin was injected into vein and 1.8 ml NS was injected into abdomen of rats in group C, 2.0 ml NS was injected into abdomen of rats in group A for control. Feed the three groups rats and test the anti-Mullerian hormone (AMH) in serum on day 0 (just before injection), day 10 and day 20 by ELISA, count the numble of follicle in bilateral ovaries on day 20. Results (1) The levels of serum AMH in the three groups before and after chemotherapy were compared: ① comparison between groups: On day 10 and day 20 , the AMH level in group B [(64.5 ± 2.9), (68.6 ± 3.4) ng/L] and group C [(76.1±4.9), (91.3±3.9) ng/L] was significantly lower than that in group A [(120.1±5.3), (121.7±4.6) ng/L;P<0.01], AMH level in group B was significantly also lower than that in group C (P=0.000). ② Comparison within groups:the AMH level on day 0 was significantly lower than that on day 10 and day 20 in group A (P<0.01), but there was no significant difference between day 10 and day 20 (P=0.427). The AMH level on day 0 was significantly higher than those on day 10 and day 20 in group B (P<0.01) and group C (P<0.01). There was no difference in AMH level between day 10 and day 20 (P=0.124) in group B, but the level was significant lower on day 10 than that on day 20 in group C (P=0.011). (2)Comparison of the number of follicles in ovaries of three groups 20 days after chemotherapy:the follicles number in group A(35±13)was greater than that in group B (16 ± 9,P=0.003) and similar with group C (31 ± 16,P=0.474) on day 20. The follicles number in group B was significantly less than that in group C (P=0.018). Conclusions In the present study, both intravenous and intraperitoneal chemotherapy have impacts on ovarian reserve function and the latter might be more serious. The level of AMH will rise again over time after chemotherapy and rats undergo intravenous chemotherapy would recover faster. The results suggest that the ovarian reserve function need more time to recover after intraperitoneal chemotherapy. For patients with ovarian cancer who want to preserve fertility function, intravenous chemotherapy might be more appropriate.

BACKGROUND:Long course of treatment and complications limit the extensive application of distraction osteogenesis, which cannot meet the clinical requirements. OBJECTIVE:To investigate the effect of general administration of eucommia alcohol extract on new bone regeneration based on the rabbit model of mandibular distraction osteogenesis. METHODS:Twenty-four New Zealand white rabbits were randomly divided into experimental group and control group. Unilateral mandibular distraction osteogenesis model was established by 1 mm/12 h distraction protocol. During the distraction period, the rabbits in the experimental group were intragastricaly administered with eucommia alcohol extract and the control animals received the same amount of physiological saline, respectively. Six weeks later, the animals were sacrificed for osteogenic testing. RESULTS AND CONCLUSION: New bone formation was observed in the distracted gap in both groups. However, the amount, mineralization and biomechanical strength of new regenerated bone in the experimental group were obviously greater than those in the control group by histological observation, dual energy X-ray absorptiometry, micro-CT and biomechanical test. General administration of eucommia alcohol extract can markedly promote distraction osteogensis in rabbit mandibular osteodistraction.

Objective To evaluate the impact of hydrogen sulfide signal system during the process of rat bone marrow-derived mesenchymal cells osteogenesis under tensile stress. Methods After the H2S signal system of cell rooms regulated by tool drugs (Group A with propargylglycine;Goup B with PBS;Group C with GYY3147), 4 000 μ strain tensile stress were applied on rat BMMCs by four-point bending apparatus for 60 minutes. Four hours later, the H2S signal system and cystathionine-γ-lyase were detected. Meanwhile, the change of the alkaline phosphate, osteocalcin, procollagen typeⅠN-terminal propeptide, and runt-related transcription factor 2 mRNA level were also examined to evaluate the osteogenic ability. Results With the increase of H2S expression, the osteogenic capacity gradually increased, while the osteogenic capacity was compromised after the endogenous cystathionine-γ-lyase was inhibited. Conclusion The H2S signal system plays an important role during BMMCs osteogensis under tensile stress. The up-regulation expression of H2S may promote osteogenesis during distraction osteogenesis.

Objective: To detect the relationship between variant of rsl255372 in transcription factor 7-Like 2(TCF7L2) gene and the type 2 diabetes mellitus (T2DM) in Tianjin Han populations. Methods: Three hundred and fifty-two T2DM patients and 176 healthy controls were randomly selected to extract the genome DNA. Denaturing high performance liquid chromatography was used to detect the PCR amplified fragment. The different peaks were chosen for sequencing. The differences of different genotype frequency between the groups were analysed. The Logistic regression was used to evaluate the risk factors of T2DM. Results: The G/T genotype frequencies of rsl2255372 were 18.5% and 2.8% in T2DM group and healthy control group respectively (P < 0.05). The G/T genotype, glycosylated hemoglobin, urea nitrogen and the systolic blood pressure were the independent risk factors of T2DM, and the high density lipoprotein was the protective factor. There was no significant difference of the G/T genotype frequency in T2DM patients with different complications. Conclusion: This study indicates that G/T genotype in the TCF7L2 gene significantly contributes to T2DM susceptibility in Tianjin Han populations. The G/T genotype is one of the risk factors of the T2DM.
