OBJECTIVE Cervical cancer is the third most malignant tumor in the world. Farnesoid X receptor (FXR) is a member of nuclear receptor superfamily. It is highly expressed in liver, kidney and small intestine, while it showed low expression level in other tissues. It not only plays an important role in the metabolism of bile acids and sugars, but also in the production of chronic inflammation in the early stage of cancer, the proliferation and migration of tumor. Compared with the normal tissue, the expression of FXR in most tumor tissues decreased. But there is no correlation between cervical cancer and FXR. So we aimed to find out the relationship between FXR and cervical cancer. METHODS A clinical study using qPCR, western blot and immunohistochemistry detected the expression of FXR in tumor tissues and normal tissues of clinical patients. FXR was activated by agonists or over-expressed by lentivirus. MTT, clone formation and flow cytometry were used to detect the relationship between FXR and proliferation of cervical cell lines. Tumor growth ability of FXR was detected by nude mice tumorigenicity. The interaction between FXR and CDKN2A-p14ARF-MDM2-p53 pathway was detected by qPCR, Western blot and immunohistochemistry. RESULTS FXR was decreased in cancer tissues compared to normal control. Activation of FXR by agonist or constitutively- over- expression of FXR inhibited cervical cell proliferation. Over- expressed FXR attenuated Caski, Hela and Siha xenograft tumor growth in nude mice compared with control. Over-expression of FXR caused G1 cell-cycle arresting and up-regulated CDKN2A-p14ARF-MDM2-p53 pathway. CONCLUSION FXR inhibits cervical cancer cell proliferation and cervical tumorigenicity which is related to CDKN2A-p14ARF-MDM2-p53 pathway. Activation or overexpression of FXR may be a potential target for the treatment of cervical cancer.

OBJECTIVE: To establish the method to analyze γ-hydroxybutyric acid (GHB) and its precursors 1,4-butanediol (1,4-BD) and gamma-butyrolactone (GBL) in urine through LC-MS/MS and provide evidence for related cases. METHODS: GHB-d6 and MOR-d3 were used as the internal standard. The urine sample was separated by LC after protein precipitation with methanol. The electrospray ion source was for ionization. Each compound was detected through multiple-reaction monitoring (MRM) mode. RESULTS: The limits of detection of GHB and its precursors 1,4-BD and GBL were 0.1, 0.1 and 2 μg/mL. The accuracy was 87.6%-98.1%. The intra-day and inter-day precisions were less than 15% and matrix effects were higher than 80%. CONCLUSION The method is high sensitive, simple, rapid, specific and with high reliability. This study has provided technical support and basic data for forensic cases involving GHB.

AlM:To observe the changes of binocular vision in V-pattern exotropia children before and after surgical correction, and the effect of training in reconstructing the binocular vision after surgical corrections.METHODS: Sixty V-pattern exotropia children were enrolled in this study and were divided into three groups according to their age:group A (4~6 years old), group B (7~9 years old), and group C (10~12 years old), 20 cases for each group. Patients received routine refraction and ophthalmic examinations. Distance and near deviation were measured by prism-covering method and synoptophore. The simultaneous perception and fusion were examined with a synoptophore, and the stereacuity was measured with stereograms ( Titmus) . The children who didn’t reconstruct binocular vision function 1wk after surgery received binocular vision training. The data were recorded before and 1 , 2, 4, and 8wk after surgery. RESULTS: Binocular vision significantly improved among the children after surgery in group A and B ( P<0. 05 ) . Significantly divergence showed between group C and the other groups 1wk after surgery ( P < 0. 05 ). Binocular vision of the three groups all significantly improved 8wk after surgery, with no significant differences (P>0. 05). CONCLUSlON: V - pattern exotropia children can benefit from early surgical correction and training after surgery in reconstruct binocular vision.

Objective To determine the levels of plasma histamine and oxidative status in patients with dermatographism before and after the treatment with anti-histamine drugs. Methods Totally, 85 patients with dermatographism were randomly divided into two groups to receive oral desloratadine and cetirizine respectively for 4 weeks. Enzyme linked immunosorbent assay (ELISA) was performed to detect the plasma level of histamine, superoxide dismutases (SOD), glutathion peroxidase (GSH-PX) and malondialdehyde (MDA) in all the patients before and after the treatment and in 15 normal human controls. The efficacy of desloratadine and cetirizine for dermatographism was estimated. Results The response rate was 83.72% and 78.57% in patients treated with desloratadine and those with cetirizine, respectively (x2 = 0.369, P> 0.05). The untreated patients with dermatographism showed an elevation in the plasma level of histamine (3.87 ± 1.21 ng/ml vs. 1.76 ± 0.56 ng/ml, P< 0.05) and MDA (3.86 ± 1.03 nmol/ml vs. 2.19 ± 0.82 nmol/ml, P< 0.05), but a decline in the activity of SOD (86.29 ± 19.9 U/ml vs. 112.12 ± 27.88 U/ml, P< 0.05) and GSH-PX (74.52 ± 47.67 vs.915.06 ± 115.96, P< 0.05) compared with the normal human controls. The treatment with antihistamine induced a reduction in the plasma level of histamine (1.61 ± 0.47 ng/ml vs. 3.87 ± 1.21 ng/ml, P< 0.05) and MDA (2.65 ± 0.77 nmol/ml vs. 3.86 ± 1.03 nmol/ml, P< 0.05), but an increment in the activity of GSH-PX (921.46 ± 157.37 vs.74.52 ± 47.67, P < 0.05) with no changes of SOD in patients with dermatographism. Conclusions In patients with dermatographism, plasma histamine is increased and there is an imbalance of oxidation-antioxidation.Desloratadine and cetirizine are effective for the treatment of dermatographism.

OBJECTIVETo investigate the influence of seasons, blood types and semen parameters on the cryosurvival rate of frozen-thawed spermatozoa from sperm donors.

METHODSWe retrospectively analyzed the influence of seasons, blood types, abstinence period, semen volume, sperm morphology, and pre-freeze sperm motility and concentration on the cryosurvival rate of frozen-thawed sperm in 4 088 semen samples from Shaanxi Human Sperm Bank.

RESULTSThe cryosurvival rate of the post-thaw sperm was correlated negatively with the progressive motility of the pre-freeze sperm (r = -0.262, P < 0.01), but positively with pre-freeze sperm concentration (r = 0.247, P < 0.01), and it was significantly higher in the 6-day abstinence group ([70.2 +/- 5.4]%) than in the other abstinence groups (P < 0.01), so was it in the normal sperm morphology rate > 20% group ([71.4 +/- 5.1]%) than in the others (P < 0.01). The survival rate of the post-thaw sperm was not correlated with seasons, blood types, and semen volume (P > 0.05).

CONCLUSIONSperm motility, concentration and morphology and the abstinence period of sperm donors may be valuable predictors of the cryosurvival rate of post-thaw sperm, but no correlation was found between the survival rate and seasons, blood types and semen volume.
