Objective To investigate the effect of different temperature moxibustion on serum IL-1β, IL-2 and TNF-αcontents in acute adjuvant arthritis rats and provide a basis for the mechanism of local anti-inflammatory and immune action of moxibustion. Methods A rat model of adjuvant arthritis (AA) was made by Freund’s complete adjuvant (FCA) modeling method. Of 32 SD rats, 8 were randomly selected as a normal group and the other 24 for model making. After successful model making, the rats were randomly allocated to model, treatment 1 and treatment 2 groups, 8 rats each. Treatment 1 and 2 groups received moxibustion. Local temperature at moxibustion point was controlled at (38±1)℃in treatment 1 group and at (45±1)℃in treatment 2 group. Rat serum IL-1β, IL-2 and TNF-αcontents were measured by enzyme-linked immunosorbent assay (ELISA). Results There were statistically significant differences in serum IL-1β, IL-2 and TNF-αcontents between the model, treatment 1 or treatment 2 group and the normal group (P<0.01). There was a statistically significant difference in serum IL-2 content between treatment 1 and the model groups (P<0.01). There were statistically significant differences in serum IL-1β, IL-2 and TNF-αcontents between treatment 2 group and the model or treatment 1 group (P<0.01). Conclusions Moxibustion has a reducing effect on serum IL-1βand TNF-αcontents and a raising effect on IL-2 content. 45℃moxibustion temperature can improve the effect of moxi bustion. The anti-inflammatory action of moxibustion may be through the mechanism of reducing serum IL-1βand TNF-αcontents and raising IL-2 content, which relieve body inflammatory reaction. The action of moxibustion needs proper moxibustion temperature.

Objective To explore the correlation between resistins rs2161490and rs1423096 genotype with type 2 diabetes mellitus (T2DM)in Guangdong.Methods Collected 178 blood of newly diagnosed T2DM in the Second Affiliated Hospital of Guangzhou Medical University from January 2015 to November 2015 as the patient group and 192 blood of healthy physi-cal examination as the control group.Analysis of the two groups of gene distribution frequency was to reach the genetic equi-librium,comparative two gene loci frequencies of resistin rs2161490 and rs1423096 in case group and control group was sta-tistically significant,and compared the distribution frequency of rs2161490 locus T→C and rs1423096 locus A→G between the patient group and the control group.Then made a logistic regression analysis:analysing the risk two loci each genotype of resistin rs2161490 and rs1423096 to T2DM,adjust of the gender and age,and the changes of the risk of the two variables. Comparative blood lipids biochemical indexes between case group and the control group,mode the correlation analysis be-tween TG,CHOL,HDL-C and LDL-C levels of serum lipids in patients with rs2161490 and rs1423096 each genotypewere performed.Results The sample was consistent with Weinberg Hardy’s law of inheritance,which was representative of the population,comparing two gene loci frequency of resistin rs2161490 and rs1423096 of case group and control group:com-parinng CT,TT,CC of rs2161490 genotype,there was no statistically significant difference (P=0.834,>0.05),and com-parinng AA,AG,GG of rs2161490 genotype,there was no statistically significant difference (P=0.960,>0.05).Each gen-otypes with T2DM risk analysis,there was no statistically significant difference(P>0.05).Adjusting the risk change after the two variables,gender and age,there was no statistically significant difference (P>0.05);TG,CHOL,HDL-C and LDL-C in each of the genes expression levels correlation analysis,there was no statistically significant difference (P>0.05).Con-clusion Analysis results showed that the frequency of two loci all genotypes in the case group and control group were no statistical significance (P>0.05).The risk of two loci gene type of rs2161490 with rs1423096 and type 2 diabetes were be-fore and after the covariate adjustment had no statistical significance (P>0.05 ).Each genotype of rs2161490 with rs1423096 and lipid levels had no statistical significance (P>0.05).Thus infer that two genotypes is not risk for type 2 dia-betes genes in guangdong area.

Objective To explore the value of combined use of laboratory indicators for diagnosis of early renal functional damage. Methods Eighty-six patients with various kidney diseases were enrolled in the Second Affiliated Hospital of Guangzhou Medical University. On admission,the serum Cystatin C(Cys C),creatinine(Cr), Urea,etc were determined. The value of using combined laboratory indicators in the diagnosis of renal functional damage was obtained through the analysis of the receiver operating characteristic curve(ROC curve);multiple variable indicators were grouped to establish multiple logistic regression models to be compared and evaluated. Results In the early and late renal injury groups(group B of 32 cases and group C of 12 cases),the serum levels of Cys C,Cr, and Urea were significantly higher than those in the normal renal function control group(group A of 42 cases),the elevation in level in group C being the most significant〔Cys C(mg/L):3.47±0.75 vs. 1.59±1.29,Cr(μmol/L):669±466 vs. 214±173,Urea(mmol/L):21.22±13.10 vs. 11.04±8.24,P<0.05 or P<0.01〕. The areas under the ROC curve(AUC)made by combinations of Cys C,Cr and Urea for the diagnosis of renal damage were 0.908,0.817 and 0.785. In the four different kinds of combination of the indicators,the AUC were sequentially arranged from large to small area as follows:Cys C+Cr+Urea=Cys C+Cr>Cys C+Urea>Cys C>Cr+Urea(0.920=0.920>0.911>0.908>0.809). In this sequence,the AUC made by Cys C+Cr+Urea and Cys C+Cr were equal,both 0.920, whose sensitivity was 75.0%,specificity 100.0%,positive predictive value 100.0%,negative predictive value 80.0%and diagnostic accuracy rate 87.5%. So,Cys C + Cr combination could be used to substitute Cys C + Cr + Urea, and the former clinical diagnostic effect was the best,much higher than that by using AUC whose curve was made by Cys C alone. Conclusion The value of using only one laboratory indicator for diagnosis of patients with early renal functional damage is not high,while applying Cys C+Cr combination can improve the diagnostic effect greatly,and its sensitivity and specificity are higher.

Objective To explore the cataract surgery quality on blindness prevention and postoperative problems in village in short period. Design Population-based survey. Participants 251 cases(254 eyes) received operation and 131 cases(134 eyes)were surveyed 6-month postoperatively. Methods Patients were examined 6-month after the small incision extracapsular cataract extraction and intra ocular lens(IOL) implantation. Examinations were conducted by a special oculist including far vision, near vision, external in- spection, anterior segment, posterior segment, intraocular pressure. Main Outcome Measures Visual acuity, intraocular pressure, diopter, eye complications of surgery. Results Naked far vision of the operated eye more than or equal to 0.3 was 41.8%, naked far vi- sion of the eye more than or equal to 0.05 was 82.8%; corrected far vision more than or equal to 0.3 was 64.2%, corrected far vision more than or equal to 0.05 was 92.3%. Naked near vision more than or equal to 0.1 was 79.9%, corrected near vision more than or e- qual to 0.1 was 85.8%. The main postoperative complications were ametropia, posterior capsule opacification(PCO), deformed pupil, pupil displacement, pigments of IOL, eccentric IOL and intraocular hypertension. The chief reasons of eyes that could not be recovered were vitreous, retina or optic nerve diseases, the key factors that caused living vision less than 0.3 were ametropia, PCO, the disease of vitreous, retina and optic nerve. Conclusions The serious complications affecting the surgery result are limited in a low range. The most important factors of the eye corrected far vision less than 0.05 are the vitreous, retina and optic nerve diseases. In order to improve the visual sight, we should add equipment to calculate the IOL diopter accurately.

Aim Toinvestigatetheroleofbrain-de-rived neurotrophic factor(BDNF)-tyrosine receptor ki-nase B (trkB ) signaling pathway in the therapeutic effects of ketamine on diabetic neuropathic pain.Meth-ods Forty-eightWistarrats,aged3months,weighing 200~250 g,were equally randomized into 4 groups(n=12 ):control group (C group ), saline group (S group),ketamine group (K group)and ketamine +ANA-12 group (KA group ).Rats in S,K and KA groups were intraperitoneally injected with a single of streptozotocin(STZ)65 mg·kg-1 to construct diabetic neuropathic pain model.After twenty-eight days,rats in S,K and KA groups were intraperitoneally injected with saline, ketamine 10 mg·kg-1 and ketamine 10 mg·kg-1 +ANA-12 0. 5 mg·kg-1 for consecutive 7 days, respectively. On the 8th day, mechanical withdrawal threshold(MWT)of rats was measured.Af-ter that,the rats were immediately sacrificed,and dor-sal ganglion of lumbar spine and prefrontal cortex (PFC)were harvested for measuring BDNF,p-trkB/trkB,synaptophysin and spine density by Western blot andglogistaining.Results ComparedwithCgroup, rats in S group significantly decreased MWT,BDNF, p-trkB/trkB,synaptophysin and spine density in dorsal ganglion and PFC (P <0. 05 ).Compared with S group,rats in K group showed a significant increase of MWT,BDNF,p-trkB/trkB,synaptophysin and spine density in the all observed regions(P<0. 05 ).On the contrary,rats in KA group showed a significant de-crease of MWT and BDNF,p-trkB/trkB,synaptophys-in and spine density as compared with K group in all regions(P<0. 05 ).Furthermore,BDNF was positive-ly correlated with spine density in all regions (P <0.05).Conclusion BDNF-trkBsignalingpathway mediates ketamine-induced therapeutic effects in dia-betic neuropathic pain.

Objective To investigate the diagnostic value of laboratory evaluation of renal injury in early diagnosis index. Methods Eighty-six patients in in-patient and out-patient of the department of urology were tested in serum C (Cys C), serum creatinine (Cr) and serum UREA nitrogen (UREA). According to the diagnostics (sixth edition), we evaluated their values for diagnosis of renal injury by analyzing the characteristics of the work curve (ROC). Results According to the renal function indexes, 3 groups were divided such as group A (normal renal function control Ccr 80 mL/min) or the Cys C, Cr, and UREA in (0.47 ± 0.24) mg/L, (85 ± 14) μmol/L, and (4.55 ± 1.33) mmol/L, group B (a decrease in renal function reserves, and renal insufficiency 20 mL/min or less Ccr < 80 mL/min) of Cys C, Cr, and UREA in (1.59 ± 1.29) mg/L, (214 ± 173) μmol/L, and (11.04 ± 8.24) mmol/L and group C (renal failure and uremia Ccr < 20 mL/min) of Cys C, Cr, and UREA in (3.47 ± 0.75) mg/L, (669 ± 466) μmol/L, and (21.22 ± 13.10) mmol/L respectively. As reducing in Ccr, Cys C, Scr and UREA concentration increased and correlated with Ccr negatively. According to the mazimum Youden index, the critical values of Cys C, Cr, and UREA were 0.90 (mg/L), 115 (μmol/L) and 7.33 (mmol/L) separately, the sensitivity (%), specificity, positive predictive value (%), negative predictive value (%), diagnostic accuracy (%) and the area of the ROC curve (AUC) were Cys C (77.3%, 97.6%, 97.0%, 81.1%, 77.3%, 0.908), Cr (65.9%, 97.6%, 96.5%, 74.1%, 65.9%, 0.817), and UREA (63.6%, 97.6%, 96.4%, 72.8%, 63.6%, 0.785) respectively. The diagnostic accuracy showed that the Cys C > Cr > UREA. Their correspounding ROC curve (AUC) were in the area of 0.908, and 0.785 and 0817. Cys C had the highest AUC (0.908), and achieved a good diagnosis effect. Conclusion Renal damage laboratory indexes of in the early diagnosis, Cys C has a higher sensitivity and specificity to be worth of clinical promotion.

Objective To explore the relationships between resistin rs1477341 , rs3219175 and type2 diabetes mellitus (T2DM) in Guangdong. Methods 180 patients of diagnosed T2DM in the Second Affiliated Hospital of Guangzhou Medical University from January 2013 to December 2014 were enrolled in the study as the treatment group and another 180 subjects taking health examination as the control group. The genotype distributions of rs1477341 locus A/T, rs3219175 locus A/G were compared and the relationship between the genotypes and T2DM were anlysed by the logistic regression. Results The frequencies of the rs1477341, rs3219175 locus genotype reached the genetic equilibrium, showed their representativeness of a population group. The frequency distribution of rs1477341 genotype was statistically insignificant across the two groups (P > 0.05). The frequency of rs3219175 genotype AA+AG was decreased while genotype GG increased significantly compared to the control group (P < 0.05). The logistic regression results suggest genotype GG may increase disease risk of T2DM which the morbidity rate of AG homozygote was 0.630 times as high as that of GG homozygote (OR =0.630, 95%CI:0.405 ~ 0.980, P < 0.05) and the morbidity rate of GG homozygote was 1.551 times as higher as that of AA+AG homozygote (OR = 1.551, 95%CI:1.016 ~ 2.368, P < 0.05). Conclusions rs1477341 genotype has no correlation with T2DM among the population in Guangdong , but rs3219175 genotype does. GG may have a higher susceptibility to T2DM.

OBJECTIVE:To provide reference for vancomycin-induced neutropenia adverse reactions/adverse events in clinical diagnosis. METHODS:With a case of children with neutropenia treated by long-course and large-dose vancomycin,PubMed and CNKI were retrieved to collect related literature and the literature was analyzed. RESULTS:Neutropenia may be associated with vancomycin,based on causality criterion of adverse reaction in China. CONCLUSIONS:Vancomycin-induced neutropenia in chil-dren is most likely associated with prolonged exposure induced by infusion,vancomycin dosage should be reduced or stopped,and routine blood and plasma concentration should be closely monitored.
