Objective To investigate the effect of glutaminase 1(GLS1)specific inhibitor BPTES[bis-2-（5-phenylacetamido-1,3,4-thiadiazol-2-yl）ethyl sulfide]on the liver fibrosis in the mouse model of liver fibrosis induced by carbon tetrachloride(CCl4).Methods Male C57BL/6J mice were intraperitoneally injected with olive oil(control group),10%CCl4(10 μL/g,model group)or 10% CCl4(10 μL/g)+ BPTES(10 mg/kg,treatment group),with 10 mice in each group,two doses a week for four weeks to establish liver fibrosis model. Collagen deposition in mouse liver tissue was observed by Sirius red staining. The expression levels of actin alpha 2(Acta2),collagen typeⅠalpha 1(Col1a1)GLS1 and GLS1 protein were detected by qRT-PCR and immunohistochemical staining.Results Compared with the control group,the liver tissue of mice in the model group was generally enlarged,the surface was not smooth and granular,and the ratio of liver mass to tibia length significantly increased(t = 2. 979,P < 0. 05);The Sirius red positive area of collagen deposition increased signifi-cantly in the liver tissue of mice in the model group(t = 7. 661,P < 0. 01),the relative expression levels of Acta2 and Col1a1 significantly increased(t = 4. 335 and 5. 319,respectively,each P < 0. 01),and the mRNA and protein levels of GLS1 significantly increased(t = 5. 319 and 9. 725,respectively,each P < 0. 01). However,compared with the model group,the BPTES treatment group had a reduction in liver mass,a significant reduction in the Sirius red positive area of collagen deposition in liver tissue(t = 7. 427,P < 0. 01),and a significant reduction in the relative expressions of Atca2 and Col1a1(t = 3. 713 and 2. 628,respectively,each P < 0. 05).Conclusion Inhibition of GLS1activity can significantly improve the degree of liver fibrosis induced by CCl4,providing a new idea for the treatment of liver fibrosis.

Objective To explore the effect of progesterone on the rate of neuronal apoptosis and nitric oxide(NO) level in the cortex and hippocampus tissue of newborn rats with hypoxic-ischemic encephalopathy(HIE).Methods Thirty 7-day-old neonatal rats were randomly divided into 3 groups:sham-operated group,hypoxic-ischemic(HI) group and pretreatment group.Rats in HI group and pretreatment group were subjected to left common carotid artery ligation,then were exposed to 80 mL/L oxygen and 920 mL/L nitrogen gas in 37 ℃ closed container for up to 2.5 h to establish HIE model.Progesterone was injected intraperitoneally into rats in the pretreatment group respectively for 30 minutes before hypoxia,and solution was injected into the sham-operated group and HI group.All rats were killed at 24 h after operation.The neuron apoptosis was identified and analyzed by flow cytometry.Nitrate/nitrite was assayed to represent nitric oxide content of brain tissues.Results The ratio of neuronal apoptosis and NO contents in cortex and hippocampus tissue in HI group [(10.09?0.36)%,(12.32?0.28)%,(51.36?9.71) ?mol/L,(52.34?4.26) ?mol/L] were significantly higher than those in sham-operated group [(2.49?0.23)%,(2.58?0.26)%,(18.16?6.24) ?mol/L,(19.28?3.58) ?mol/L)](P_a

This paper studied the relationship between apolipoprotein E isoforms and hyperlipidemia among 92 cases of diabetes mellitus, 174 cases with impaired glucose tolerance and 124 sex-age-matched controls. The results demonstrated that the patients with abnormal glucose tolerance had higher frequency of E2/3 isoforms and lower frequency of E, / , in com parison with controls. Hyperlipoproteinemia were mainly related to hyperglycemia but the Apo E isoforms which ex pressed different alleles also associated with hyperlipoproteinemia.

Lymph node metastasis is the main prognostic factor of endometrial cancer patients.As the metastasis of early endometrial cancer patients is very low,it remains a controversy whether these patients are necessary to undergo conventional lymphadenectomy and a challenge to confirm the scope of lymph node dissection.We intend to demonstrate the application of lymphadenectomy in patients with early endometrial cancer via the impact of lymphadenectomy on the prognosis of these patients.The risk factors for lymph node metastasis of endometrial cancers were analyzed to explore its value in the surgical option.Furthermore,the guidance of sentinel lymph node in surgical staging and prognostic prediction of early endometrial cancer was explored to clarify the applied condition and scope of lymphadenectomy in these patients.

We investigated the distribution of Chlamydia trachomatis genotypes in the outpatients visiting STD clinics in Fuzhou City ,China .Between 2013 and 2014 ,a total of 2 019 urethral or endocervical specimens from susceptible genital C .trachomatis infections were collected and detected by using real‐time PCR assay kit .The C .trachomatis‐positive specimens were subsequently amplified with nested PCR for Omp1 region and analyzed by sequencing .Genotyping was performed by BLAST similarity search and phylogenetic tree analysis .Eighty‐three of the 86 C . trachomatis‐positive specimens were suc‐cessfully sequenced .Only one specimen was identified as multiple infection .Eight different genotypes were identified .The most prevalent was F (36 .59% ) ,followed by E (24 .39% ) ,D (12 .20% ) ,G (9 .76% ) ,J (9 .76% ) ,H (3 .66% ) ,K (2 .44% ) and B (1 .22% ) .Synonymous mutation rate and non‐synonymous mutation rate among Omp1 genes of different geno‐types were calculated .All genotypes but G showed dN/dS values of<1 .Genotypes F and E were commonest .Synonymous sub‐stitution was the major pattern of variation in the process of Omp 1 gene evolution .

Objective: To observe the clinical efficacy of uplifting massage therapy in the treatment of cervical intervertebral disc protrusion and study the effectiveness of this massage therapy for cervical intervertebral disc protrusion. Methods: 116 subjects were randomized into two groups: treatment group in which 60 cases were treated by uplifting massage therapy and conventional massage, and control group in which 56 cases were treated by simple conventional massage. Results: After 1-2 courses of treatment, the total effective rate was 95.0% in treatment group and 80.4% in control group; the former rate was higher than the latter one(P＜0.05).Conclusion: The uplifting massage therapy combined with conventional massage has better effects than simple conventional massage in the treatment of cervical intervertebral disc protrusion.

Ningxiang pigs fat-type breeds have been increasingly used in biomedical research due to the character -istics of genetic stability , high food value , fast growth , adaptability and strong reproductive ability .The recent development in research on Ningxiang pigs in a closed group training , inbred cultivation , biological characteristics and medical applica-tion is reviewed in this article .Ningxiang pigs have been closed-bred for fourteen years , and may be applied in biomedical research such as artery atherosclerosis and diabetes mellitus .
