AIM: To examine COX-2 expression in esophageal carcinoma,and to study relationships between COX-2 expression and clinicopathological features and prognosis of esophageal carcinoma patients.METHODS: 89 paraffin-embedded tissue samples from patients with esophageal carcinoma were collected,its clinicopathological features such as tumour differentiation,depth of invasion,length and site of the tumor,regional lymph node metastases,distant metastasis were recorded.Survival time of 81 cases were also recorded.By SP immunohistochemistry method,the expression of COX-2 in tumor samples was examined.RESULTS: COX-2 expression in esophageal carcinoma was markedly higher than that in nomal esophagus,the expression was higher in less differentiated and deeper invaded cases(P0.05).Cases of esophageal carcinoma with lower COX-2 expression had longer survival time than those with higher COX-2 expression(P

Objective To study the effect of blood glucose level and duration of type 2 diabetes mellitus on carotid intima-media thickness (CIMT) and quantitative carotid stiffness (QCS) in the patients with type 2 diabetes mellitus. Methods Two hundred and seventy-four type 2 diabetic patients (diagnosed according to the World Health Organization criteria) were involved in this study. The subjects were divided into three groups according to the HbAlclevels and duration of diabetes mellitus: 60 with duration ≤2 years (as newly diagnosed) , 96 with duration≥5 years and HbAlc <6.5%, and 118 with duration≥5 years and HbAlc≥6.5%. CIMT and QCS of the common carotid artery were assessed by the high-resolution B-mode ultrasound unit and an echo-tracking system integrated in an uhrasound unit respectively. Results (1) In categorical analyses, the mean level of CIMT was increased from 720 μm in subjects with a duration of diabetes mellitus ≤2 years to 770 μm in subjects with a duration of diabetes mellitus > 2 years and plasma HbAlc< 6.5% (P < 0.05), and to 800 μm in subjects with a duration of diabetes mellitus > 5 years and plasma HbAlc≥ 6.5 % (P < 0.01). The corresponding values for Q CS values were 4.5, 4.5 and 5.1 (P <0.05), respectively. (2) In multiple stepwise regression analyses, CIMT wassignificantly associated with the duration of diabetes mellitus, systolic blood pressure and serum concentration of total cholesterol, whereas QCS was significantly associated with age, duration of diabetes mellitus, smoking, HbAlc, systolic blood pressure (P < 0.05 or P < 0.01). Conclusion QCS is suitable in evaluating the impact of blood glucose on carotid artery, while CIMT is an appropriate tool for long-term follow-up of diabetic patients.

Objective To observe the effect of rosuvastatin calcium on lipid,vascular endothelial growth factor (VEGF),nitric oxide (NO),tumor necrosis factor (TNF)-α and interleukin (IL)-1 in hyperlipidemia patients.Methods One hundred and twenty-seven hyperlipidemia patients were randomly divided into two groups.Patients in the study group included 72 patients which were given rosuvastatin calcium 10 mg and enteric-coated aspirin 100 mg,orally,once a day for 8 weeks.The control group included 55 patients which were only given enteric-coated aspirin 100 mg,orally,once a day for 8 weeks.The change of lipid,VEGF,NO,TNF-α and IL-1 was observed before and after treatment.Results Before treatment,the level of total cholesterol(TC),triglyceride (TG),low density lipoprotein-cholesterol (LDL-C),high density lipoprotein-cholesterol (HDL-C),VEGF,NO,TNF-α and IL-1 in two groups had no significant difference (P ＞ 0.05).After treatment,the level of TC,TG,LDL-C,TNF-α and IL-1 in study group were significantly lower than those in control group [(4.410 ± 0.688) mmol/L vs.(6.491 ± 0.744) mmol/L,(1.762 ± 0.834) mmol/L vs.(2.632 ± 0.792) mmol/L,(2.256 ± 0.347) mmol/L vs.(4.544 ± 0.493) mmol/L,(41.14 ± 5.41) ng/L vs.(71.34 ± 6.76) ng/L,(0.22 ± 0.18) μ g/L vs.(0.42 ± 0.23) μ g/L] (P ＜ 0.05).The level of HDL-C,VEGF and NO in study group were significantly higer than those in control group [(1.807 ± 0.730) mmol/L vs.(1.432 ± 0.514) mmol/L,(564.86 ± 120.02) ng/L vs.(451.23 ± 100.72) ng/L,(42.39 ± 6.71) μ mol/L vs.(33.65 ± 6.24) μ mol/L](P＜ 0.05).No adverse reaction occurred in two groups.Conclusions Rosuvastatin calcium can obviously decrease the level of lipid,elevate the expression of VEGF and NO,and reduce the expression of TNF-α and IL-1.Rosuvastatin calcium can improve vascular endothelial function obviously in hyperlipidemia patients.

ObjectiveTo explore the diagnosis and prognosis value of clinical pneumonic infection score (CPIS) in patients with stroke-associated pneumonia (SAP).MethodsOne hundred and fifty stroke patients were evaluated and analyzed by CPIS.SAP was regarded as gold standard,and sensitivity,specificity,diagnose accordance rate,positive predictive value and negative predictive value were calculated.Results Thirty-nine patients had SAP and 111 patients did not have SAP by CPIS,and the incidence of SAP was 22.0％ (33/150).CPIS diagnostic sensitivity was 84.8％ (28/33),specificity was 90.6％ ( 106/117 ),positive predictive value was 71.8％ (28/39),negative predictive value was 95.5％ (106/111),and diagnose accordance rate was 89.3％(134/150).The patients of SAP were divided into good prognosis (28 cases) and bad prognosis (5 cases),and the CPIS was significantly lower in patients of good prognosis 7 days after SAP than that in patients of bad prognosis[(4.21 ± 2.23) scores vs. (6.05 ±2.32) scores,P ＜0.05].ConclusionsNot only CPIS has higher diagnosis rate in SAP incidence,but also has good judgment to prognosis.It is worthy of clinical application.

Aim To compare the interactions of baicalein and baicalin with bovine serum albumin (BSA) and their mechanism. Methods The binding reactions of baicalein and baicalin with BSA and the effects of glucose on them were studied by spectroscopy to compare the binding constants and binding distances of baicalein-BSA and baicalin-BSA,which were calculated according to Lineweaver-Burk equation and F?ster' energy transfer theory. Thermodynamic parameters were used to calculate the types of interaction force between BSA with baicalein or baicalin and the technique of synchronous fluorescence spectra was used to observe the effects of baicalein or baicalin on the conformation of BSA. Results Both the binding constants and binding distances of baicalein-BSA and baicalin-BSA decreased with temperature increasing and were increased by glucose. Relative to baicalein,the binding affinity of baicalin to BSA decreased obviously with an increase in binding distance. Both baicalein and baicalin could form non-covalent compounds with BSA mainly to quench the intrinsic fluorescence of BSA through a static quenching procedure. Baicalein could interact with BSA through hydrogen bonds and Van der Waals force,and baicalin did it mainly through electrostatic force. Though baicalein or baicalin could induce the conformational changes of BSA by binding reaction,only the former reduced the hydrophobicity in microenvironment around the tryptophan moieties of BSA. Conclusions The glycosylation substitution of baicalein molecule can decrease the binding to BSA (baicalin-BSA) and change the types of interaction force. The physiological concentration of glucose increases the binding constants and the number of binding sites of baicalein and baicalin with BSA.

Lesch-Nyhan syndrome(LNS) is a congenital X-linked recessive inherited disorder caused by mutations in the hypoxanthine guanine phosphoribosyl transferase (HPRT) gene.A deficiency of the HPRT enzyme is responsible for the disease.The main clinical manifestation includes hyperuricemia, juvenile-onset gouty arthritis and neurological developmental disorders.Studies have reported there are more than 400 HPRT gene mutation sites, but the incidence of LNS in the Chinese population is extremely low.Here we report a 16-year-old male patient who suffered neurological dysfunction at an early age and gouty arthritis in his youth.DNA of patient and his family members were extracted from peripheral blood lymphocytes.The coding region and the intron-exon boundaries of HPRT gene were sequenced by standard methods.We found a mutation in exon 3 of the HPRT gene of the patient and his mother (Exon3:c.143G>A), which resulted in an arginine to histidine (p.R48H) substitution in the encoded protein.No activity of the enzyme HPRT was detected in the erythrocytes.The same mutation was reported in several European families, but was found in Chinese family for the first time.Clinicians in China have poor experience in diagnosing LNS case, due to the low incidence in China.Therefore LNS screening for infants or adolescents with hyperuricemia, gouty arthritis and neurological dysfunction should be performed.

The clinical data and the genetic study results of a patient with Liddle syndrome were reported.The genomic DNA of peripheral blood mononuclear cells was extracted and the mutation sites of all the exons in 36 genes related to hypokalemia were screened by high-throughput sequencing.Genetic validation of patients and their parents was performed by direct sequencing.The patient presented with severe hypokalemia,low aldosterone and hypertension.The results of gene sequencing showed that the SCNN1B gene exon 13 584 codon 1751C-T,and the corresponding encoded amino acid changed from alanine to valine (A-V).Eleven families and 33 cases of Liddle syndrome diagnosed by genetic analysis were reported in Chinese literature from 1998 to June 2018.The literature review showed that all patients had hypertension,87％ (28/32) had hypokalemia and 85％ (23/27) had low aldosterone.The onset age of 21 patients was＜20 year,among whom cerebral stroke occurred in 3 patients.The normal blood pressure can be achieved by low-salt diet and administration of amiloride or triamterene.The most common mutations were missense mutations (7/11).Liddle syndrome is a controllable and treatable disease,early detection,diagnosis and treatment can avoid serious complications.
