OBJECTIVE:To analyze the cost-effectiveness of two regimens in the treatment of chronic hepatitis B fibrosis. METHODS:112 cases of chronic hepatitis B fibrosis were divided into Compound biejia ruangan tablet group (group A,n=56) and Anluo huaxian pill group(group B,n=56). Both groups received Entecavir dispersible tablets combined with relevant Chinese patent medicine. The liver fibrosis index and transient elastography of 2 group were detected before and after treatment,TCM symp-tom score and effective rate calculation were conducted to compare the cost-effectiveness of 2 groups. RESULTS:The cost,effec-tive rate and cost-effectiveness ratio of group A were 9 227.10 yuan,74.11% and 12 451;those of group B were 8 202.90 yuan, 69.28%and 11 840;incremental cost-effectiveness ratio was 21 205. Group B showed a better cost-effectiveness. Result of sensitiv-ity test was same to that of cost-effectiveness analysis. CONCLUSIONS:The cost-effectiveness of Anluo huaxian pill combined with Entecavir dispersible tables is better than Compound biejia ruangan tablet combined with Entecavir dispersible tables in the treatment of chronic hepatitis B fibrosis.

Objective To investigate the effect of CDH1 3'-UTR + 54C/T single nucleotide polymorphism(SNP) on expression of luciferase reporter gene and its association with susceptibility to cervical cancer. Methods The luciferase gene expression vectors containing CDH1 3'-UTR +54C/T SNP C or T allelotype were constructed. The effect of CDH1 3'-UTR + 54C/T SNP on expression of luciferase reporter gene in 293 T cells were tested by daul lucfferase reporter assay system. The CDH1 3'-UTR + 54C/ T SNP was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis in 280 cervical cancer patients and 330 healthy controls. Results The lucfferase activity analysis showed that the relative luciferase activity (RLA) of 293T cells with C allelotype was 1.46, which was significantly lower than that of the 293 T cells with T allelotype (3.01; t=2. 94, P =0. 042). There was no significant difference in age distribution between the cervical cancer patients and the healthy controls. The genotype frequency distribution of CDH1 3 '-UTR + 54C/T SNP in healthy controls did not significantly differ from that expected by Hardy-Weinberg equilibrium (P>0.05). The C allelotype frequency of CDH1 in cervical cancer patients was 80. 7%, which was significantly higher than that in healthy controls (74. 5%;χ2 =6.59, P=0.010). The T/T, T/C and C/C genotype frequencies of cervical cancer patients and healthy controls were 4. 3%, 30. 0%, 65. 7% and 5. 8%, 39. 4%, 54. 8%, respectively, which were significandy different (χ2=7.45, P =0.024). Compared with individuals with T/T or T/C genotypa, individuals with C/C genotype had significantly higher risks of developing cervical cancer (OR = 1. 578,95%CI=1.136 -2.191). Conclusion The C allelotypa of CDH1 3'-UTR + 54C/T SNP might decrease the expression of lucfferase reporter gene and the C/C genotypa might be a potential risk for cervical cancer development.

ObjectiveTo investigate the clinical efficacy of warm needling moxibustion plus tricolor medicinal paste in treating knee osteoarthritis.MethodNinety-one patients meeting the diagnostic criteria were randomly allocated to a treatment group (45 cases) and a control group (46 cases). The treatment group was given warmneedling moxibustion plus tricolor medicinal paste and the control group, warm needling moxibustion alone. The clinical therapeutic effect and the WOMAC score were observed in thetwo groups. An improvement in the symptoms of knee osteoarthritis was assessed in the patients after treatment.ResultIn both groups, there were statistically significant pre-/post-treatment differences in the pain and daily activity scores and the WOMAC total score (P<0.05) but not in the morning stiffness score (P>0.05). There were statistically significant differences in the daily activity score and the WOMAC total score (P<0.05) but not in the pain and morning stiffness scores (P>0.05) between the two groups.Conclusion The study shows that warm needling moxibustion plus external application of tricolor medicinal paste has a marked improving effect on the pain, swelling and physiological functions in patients with knee osteoarthritis. Improving lower limb function further in daily activities can produce a satisfactory and stable therapeutic effect.

Objective To evaluate the effect of isoflurane anesthesia on noise-induced hearing loss in guinea pigs.Methods Forty-eight healthy adult male guinea pigs,aged 3 months,weighing 400-500 g,were randomly divided into 4 groups (n =12 each) using a random number table:control group (C group),isoflurane group (I group),noise-induced hearing loss group (N group),and isoflurane + noise-induced hearing loss group (I + N group).Isoflurane was inhaled for 140 min at a concentration of 1% in I and I + N groups.N and I + N groups were exposed to the noise of 4 kHz center frequency and 118-122 dB sound pressure level for 120 min starting from 20 min after administration.Mean arterial pressure (MAP) was recorded at 10,40,70,100 and 120 min of exposure to noise and cochlear blood flow (CoBF) was recorded before administration and at 10,40,70,100 and 120 min of exposure to noise.Auditory brainstem response (ABR) threshold was recorded before administration and at 1 h,72 h,and 10 days after the end of exposure to noise.Arterial blood samples were obtained and the plasma noradrenaline (NE) concentration was detected by HPLC before exposure to noise and immediately after the end of exposure to noise.Results Compared with group C,MAP and the change rate of CoBF were significantly decreased,and the plasma NE concentration was increased immediately after the end of exposure to noise in I group,and MAP was increased,the change rate of CoBF was decreased,and the plasma NE concentration immediately after the end of exposure,and ABR threshold after the end of exposure were increased in N and I + N groups.Compared with N group,MAP was significantly decreased,the change rate of CoBF was increased,the plasma NE concentration immediately after the end of exposure,and ABR threshold at 1 and 72 h after the end of exposure were increased,and no significant was found in ABR threshold at 10 days after the end of exposure in I + N group.Conclusion Isoflurane anesthesia exerts temporary but not permanent protective effects against noise-induced hearing loss in guinea pigs and partial inhibition of activation of sympathetic nerve and increased CoBF may be involved in the mechanism.

The effects of linking loop structure between guanine ( G) repeats on G-quadruplex formation were investigated. The results show that the unfavorable effects of long linking loops on G-quadruplex formation can be overcome by introducing double-stranded structures in linking loop regions. This finding provides a new way for sensor design. The activity of G-quadruplex DNAzyme can be tuned by utilizing target-mediated formation of double-stranded structures in loops. As an example, T-T mismatches are introduced in loops to destroy double-stranded structures. The stabilization of Hg2+ to T-T mismatches promotes the reformation of double-stranded structures. Correspondingly, the oligonucleotide folds into G-quadruplex, which binds with hemin to form peroxidase-like G-quadruplex DNAzyme. Hg2+ sensor is designed based on this principle. Using this method, Hg2+ quantitation is achieved in the concentration range of 10-700 nmol/L, with a detection limit of 8. 7 nmol/L. Cysteine will compete with T bases to bind with Hg2+, releasing Hg2+from T-Hg2+-T base pairs. Thus cysteine can also be quantified with this system in the concentration range of 20-700 nmol/L, with a detection limit of 14 nmol/L.
