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.

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 .

Forty cases of low back pain due to climacteric osteoporosis were treated by needling Fengchi (GB 20), Dazhui (GV 14), Geshu (BL 17), Tianzong (SI 11) and Ashi points, as well as oral Chinese herbs. Results showed cure in 25 cases, improvement in 9 cases and failure in 6 cases, with the total effective rate of 85.0%.

This article summarizes the literature since 1990s. The research progress was surveyed from the perspectives of filiform needling, moxibustion, acupoint injection, acupuncture and massage,acupuncture and traction. In the treatment of cervical vertigo, acupuncture acts to dilate blood vessels,diminish vessel resistance and increase blood flow, hence to improve micro-circulation and oxygen supply to the brain.

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.

Objective To explore the influence of fluid management and prognosis guided by goal direction on patients undergoing gastrointestinal surgery.Methods Eighty ASA grade Ⅰ-Ⅲ,consecutive consenting patients undergoing gastrointestinal surgery were divided into observation group (40 patients)and control group (40 patients) by random digits table method.The intraoperative fluid management in control group was based on central venous pressure(CVP),and kept CVP at 8-10 mmHg(1 mmHg =0.133 kPa).The intraoperative fluid management in observation group was based on stroke volume variation (SVV),and kept SVV at 10 ％-12％.The operation time,intraoperative and postoperative 3 d fluid management,time of defecation and exhaust,time of full or semi-liquid diet,length of stay in hospital,rate of complications after operation for 48 h between two groups were compared.Results The volume of total fluid,colloid solution and crystalloid solution received during operation in observation group were significantly lower than those in control group[(2 686.0 ± 977.5) ml vs.(4 837.5 ± 1 566.0) ml,(792.4 ± 197.6) ml vs.(1 284.6 ± 356.7)ml,(1 894.9 ± 460.4) ml vs.(3 569.9 ± 1 318.7) ml] (P ＜ 0.05).The time of semi-liquid diet,length of stay in hospital in observation group were significantly lower than those in control group [(171.1 ± 45.3) h vs.(235.8 ±89.5) h,(11.4 ±1.8) d vs.(14.7 ±4.9) d] (P＜0.05).The time of full liquid diet,time of defecation and exhaust between two groups had no significant difference(P ＞ 0.05).The rate of complications between two groups had no significant difference(P ＞ 0.05).Conclusion Compared with monitoring CVP,the fluid management based on SVV can decrease the fluid volume during operation and shorten the length of stay in hospital.
