Objective To evaluate the relationship between the existence of DME and the SFCT in DR pa-tients. Methods We collected 70 cases which were clinical diabetic involving 122 eyes. They are 36 men with 64 eyes and 34 women with 58 eyes. The average age is 56.7 ± 9.7 year-old. All patients had been examined by oph-thalmologic examination. Grouping: patients without diabetic retinopathy (NDR) group; mild-to-moderate NPDR group; severe NPDR group; PDR group. The last three groups were divided into two subgroup groupsrespectively , which were cases with and without significant macular edema (CSME + / CSME). EDI was used to measure the SFCT. SPSS 17.0 software was used for statistical analysis. Results The average SFCT of NDR group, mild-to-moderate NPDR group, severe NPDR group and the PDR group respectively were (282.94 ± 104.21)μm, (313.62 ± 94.40)μm, (382.44 ± 76.91)μm, (335.00 ± 73.82)μm. Compared with the NDR group, SFCT was thicker than the other three groups, and difference was statistically significant (F = 2.786, P = 2.786). There were no statisti-cally significant difference of SFCT between the mild-to-moderate NPDR/CSME - group and mild-to-moderate NPDR/CSME + group, severe NPDR/CSME - group and severe NPDR/CSME + group PDR/CSME-group, PDR/CSME + group. Conclusions The SFCT of DR patients could potentially be thickenedas disease became serious. When considered the same degree DR, there is no obvious difference of SFCT between patients with CSME and without CSME.

Objective To assess the academic influence of research on blood pressure in the world and its frontiers. Methods Papers on blood pressure published from 2004 to 2008 and from 2009 to 2013 in China and foreign coun-tries were retrieved from Web of Science. Their academic influencing power was assessed and their evolution in the past 10 years was displayed by Citespace. Results The world outputs in research on blood pressure increased steadily from 2004 to 2014. The competitive force of the USA-led developed Western countries was strong and stable. The out-puts in research on blood pressure in China increased rapidly, but its influencing power was relatively low. Although progress was made at micro and macro levels,greater advances were achieved at gene,molecular and big data levels in the past 10 years. Conclusion The USA and European countries-led development in research on blood pressure is steady, and it is urgent for China to reduce its gap with USA and European countries.

Objective To evaluate the possible association among serum folate,polymorphisms related reduced folate carrier gene (RFC-1) AS0G,methionine synthase reductase gene (MTRR) A66G,and cervical cancer,and to provide clues for the etiology of cervical cancer.Methods Based on a hospital-based case-control study,107 cases diagnosed as cervical cancer pathematologically and 107 controls with hysteromyoma,were selected by frequency,matched with age and habitation.Serum folate concentration was detected by RIA and polymorphism RFC-1 A80G and MTRR A66G was examed by RFLP-PCR.Results Serum folate concentration in patient group [(1.86±0.60) ng/rml] was significantly lower than that in control group [(2.30 ± 1.14) ng/ml],and risk of cervical cancer increased with the decreased serum folate levels (x2trend =12.57,P =0.001).Risks to catch cervical cancer for women with RFC-1 80 GG were 2.42 times (95 ％ CI 1.01-5.81) as much as for those with RFC-1 80 AA,and 1.65 times (95 ％ CI 0.77-3.53) for those with RFC-1 80 AA and RFC-1 80 AG,risks to catch cervical cancer for women with MTRR 66 GG were 1.35 times (95 ％ CI 0.40-4.56) as much as for those with MTRR 66 AA and 1.26 times (95 ％ CI 0.38-4.16) for those with RFC-1 80 AA and RFC-1 80 AG.Conclusion Serum folate deficiency to a certain degree can increase the risk of cervical cancer.RFC-1 A80G mutation may be a risk factor for cervical cancer and homozygous (GG) gene may increase the susceptibility of cervical cancer.MTRR A66G gene mutation may have nothing to do with cervical cancer.

Objective To investigate the effect of different pressures of hyperbaric oxygen (HBO) treatment on neuropathic pain (NP) in rats.Methods Twenty-four healthy male Sprague-Dawley rats were randomly divided into 4 groups (n =6 each):sham operation group (group S),NP group,treatment with HBO at 2.0 atmosphere absolute group (group HBO2.0) and treatment with HBO at 2.5 atmosphere absolute group (group HBO2.5).The animals were anesthetized with intraperitoneal 5 ％ chloral hydrate 300 mg/kg.NP was induced by chronic constrictive injury.The left sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1-mm intervals with 4-0 silk thread.After the rats were placed in the HBO chamber,the pressure was increased at a rate of 10 kPa/min until the desired pressure was reached,and then the pressure was maintained at this level for 60 min.The pressure was then decreased at a rate of 10 kPa/min until the normal pressure was reached.HBO treatment was performed once a day for 5 consecutive days starting from 1st day after operation in groups HBO2.0 and HBO2.5.While the rats were only placed in the HBO chamber and stayed for 100 min in groups S and NP.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 0,1and 2 h after leaving the HBO chamber (T0.2).Results Compared with group S,MWT was significantly decreased and TWL was shortened in group NP (P ＜ 0.05).Compared with group NP,MWT was significantly increased and TWL prolonged at T1 during the treatment (P ＜ 0.05),while no significant change was found in MWT and TWL at T2 during the treatment in groups HBO2.0 and HBO2.5 (P ＞ 0.05).There was no significant difference in MWT and TWL at each time point during the treatment between groups HBO2.0 and HBO2.5 (P ＞ 0.05).Conclusion Treatment with different pressures of HBO can reduce NP in rats,but the change in pressure dose not affect the analgesic efficacy.

Objective To investigate the efficacy and safety of oxycodone hydrochloride controlled-release tablets combined with gabapentin in the treatment of painful diabetic neuropathy.Methods Eighty patients with painful diabetic neuropathy were divided into group A and group B with 40 cases each by random digits table.Patients of group A received simple oxycodone hydrochloride controlled-release tablets,while patients of group B received oxycodone combined with gabapentin.The intensity of pain, oxycodone dosage, quality of life and adverse effect in two groups was observed and compared.Results The pain was obviously relieved in two groups, and the effective analgesic rate at 21-28 d after treatment in group B was superior to group A[95.0% (38/40) vs.62.5% (25/40)], there was significant difference between two groups (P＜0.05).Numerical rating scale NRS score at 28 d after treatment in group B and group A was 1.2 ± 0.3 and 2.8 ± 0.5 respectively,and there was significant difference between two groups (P＜ 0.01 );the oxycodone dosage at 28 d after treatment in group B was lower than that in group A[(32.2 ± 4.3 )mg vs.(40.3±5.5 ) mg], and there was significant difference between two groups (P ＜ 0.05 ); the quality of life in group B was superior to group A, and there was significant difference between two groups (P ＜ 0.05 or ＜ 0.01 );the incidence of dizzy at 7, 14 d after treatment in group B was higher than that in group A[35.0% (14/40) vs.15.0% (6/40) and 30.0% (12/40) vs.10.0% (4/40)],and there was significant difference between two groups (P ＜ 0.05 ).Conclusion Oxycodon hydrochloride controlled-release tablets combined with gabapentin is effective and safe for the management of painful diabetic neuropathy.

On the basis of the development of a new CE method for the analysis of α-lactalbumin (α-Lac), β-lactoglobulin A(β-LgA) and β-lactoglobulin B(β-LgB), different concentrations of acetic acid (HAc) and trichloroacetic acid (TCA) for the removal of proteins in raw milk, infant formula A and B, and yogurt were investigated.It was shown that TCA is better than HAc for eliminating of proteins in the above four samples.The proteins in 2 g of raw milk could be eliminated by 3 mL of 100 g/L TCA.0.5 g of infant formula A and B needs 5 mL of 10 g/L and 20 g/L TCA to remove the proteins, respectively.For 2 g of yogurt, 3 mL of 20 g/L TCA is enough.The present research may provide valuable information for protein-containing sample (such as raw milk, infant formula and yogurt) pretreatment.

Objective To study whether serum matrix metalloproteinase 9, serum transforming growth factor ? 1, serum type C IV collagen concentrations are alternatoin in various stages of patients with T2DM. Methods 64 cases T2DM patients were divided into three groups according to urine albumin excretion rate (UAER):normoalbuminuria (NA)group and microalbuminuria (MA) group and overt diabetic nephropathy (ODN)group. Serum MMP 9,TGF ? 1 and C IV were detected in all cases. Results Serum MMP 9 in MA and ODN groups were higher than NA and normal control groups ( P

Objective To evaluate GGT in combination with B ultrasound for the diagnosis of biliary atresia (BA) infants suffering from obstructive jaundice.Methods A retrospective analysis was made on 69 sick infants including 55 BAs and 14 non-BAs as identified by intraoperative cholangiography.The preoperative laboratory GGT and ultrasound data were collected and analyzed.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy were compared.Results BA patients had significantly higher GGT than Non-BA patients (t =-4.164,P ＜ 0.05).The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of GGT ＞ 306 U/L were 69.1％,92.9％,97.4％,43.3％,73.9％,respectively.In BA group,abnormal gallbladder was significantly associated with proadening portal vein,broadening hepatic artery compared with Non-BA patients (x2 =9.995,P ＜0.05).The accuracy of abnormal gallbladder on ultrasound was 78.3％.When two method combined for the diagnosis of BA,the sensitivity,specificity,positive predictive value,negative predictive value were 92.7％,92.9％,98.1％ and 76.5％ and accuracy can reach 92.8％.Conclusions For obstructive jaundice infants with GGT ＞ 306 U/L and abdominal gallbladder ultrasound finding intraoperative cholangiography should be carried out to make definite diagnosis of BA.
