Objective To explore the change of thyroid hormones and leptin at hyperuricemia (HUA)/gout.Methods A total of 96 primary gouts,65 HUAs,and 59 healthy examiners was selected.Height,weight,blood pressure,renal function,serum uric acid(SUA),glucose,lipid profiles,insulin,thyroid hormones were measured after an overnight fast.Results (1) The prevalence of subhypothyriodism at gout and HUA was 7.29％ and 15.38％,respectively.They were higher than that at healthy subjects.(2) Body mass index (BMI),systolic blood pressure (SBP),triglyceride (TG),cholesterol (CHO),thyroid stimulating hormone (TSH),fasting insulin (FINS),homeostasis model assessment of insulin resistance (HOMA-IR),and serum leptin level were increased remarkably at gout/hyperuricemia relative to control group,whereas,free thyroid hormone (FT4) was decreased.(4) In the gout and hyperuricemia groups,TSH was used as the dependent variable for the linear multivariate regression analysis,the results showed that sex,age,BMI,SUA,FT4,HOMA-IR,and Leptin were included in the regression equation of TSH (βwere-0.27,0.832,0.946,0.198,-0.942,0.895,and 0.650,respectively).Conclusions The prevalence of subhypothyroidism in primary gout/hyperuricemia was increased.Female,age,BMI,SUA,FT4,HOMA-IR,and leptin were the independent risk factors.Insulin resistant and leptin played the media roles in the gout/HUA and hypothyroidism.

Objective To observe the effects of liver-discharging and stomach-harmonizing therapy on quality of life in senile patients with reflux esophagitis and to evaluate the therapeutic effect of traditional Chinese medicine (TCM) on chronic diseases. Methods Sixty patients with senile reflux esophagitis selected from in-patients and out-patients of Henan Province Hospital of TCM from March 2012 to October 2013 were randomly divided into experimental group and control group(each,30 patients). The experimental group was treated with Xiaoyao powder (its ingredients could be added or subtracted according to the patient's individual situation)combined with omeprazole and domperidone,while in the control group,only western drugs,omeprazole and domperidone were applied. The therapies in both groups lasting for 8 weeks constituted one therapeutic course. The MOS 36-item short form healthy survey(SF-36)was used to evaluate the degree of improvement of patients,quality of life,and clinical effects and adverse drug reaction were observed. Results The total scores of SF-36,physical and mental health scores of both groups were increased significantly,and the degree of elevation in scores in the experimental group was markedly higher than that in the control group(total scores of SF-36:124.2±11.5 vs. 117.1±10.9,physical health scores:67.9±5.3 vs. 62.9±6.2,mental health scores:56.1±6.7 vs. 55.0±6.6,all P<0.05). The total effective rate of experimental group was much superior to that of control group(96.7%vs. 80.0%,P<0.05). No obvious adverse reactions happened in the two groups. Conclusion Liver-discharging and stomach-harmonizing therapy can improve the quality of life in aged patients with reflux esophagitis.

Objective: To evaluate the adaptation of different materials for gingival layer in Class Ⅱrestorations using Micro-CT.Methods:Eighteen extracted human premolars were selected, and ClassⅡcavities were prepared.The teeth were randomly divided into six groups and restored using layering tech-nique.Six materials were used for gingival layer, including four injectable materials:Beautifil Flow Plus F00 (F00), Beautifil Flow F10 (F10), Filtek Z350 Flowable (Z350F), FujiⅡLC CAPSULE (Fuji), and two packable materials: BeautifilⅡ (BF), Filtek Z350 (Z350).The restored teeth were scanned with micro-CT and the images were 3D reconstructed to evaluate the volumes and the distribution of the voids on the restoration-tooth interface of the gingival layer.The volume of the voids were statistically analyzed using nonparametric Jonckheere-Terpstra tests.Results: The volumes ( mm3 ) of the voids on the restoration-tooth interface were: Z350F (0.000 15), F10 (0.000 39), F00 (0.012), Fuji (0.070), Z350 (0.16) and BF (0.20).There were significant differences between Z350F/F10 and Fuji/Z350/BF (P<0.05).Most of the voids were found on the point-line angles of the cavities.Con-clusion:The voids on the restoration-tooth interface were mainly on the point-line angles of the cavities. Injectable materials with high flowablility could reduce the restoration-tooth interface voids significantly when used for the gingival layer in ClassⅡrestorations.

Objective To investigate the incidence of surgical site infection(SSI)following clean incision breast surgery under non-local anesthesia,and evaluate risk factors for SSI.Methods Clinical data of 3 327 patients who underwent clean incision breast surgery under non-local anesthesia in 22 hospitals in Fujian Province were surveyed retrospectively,SSI and risk factors were analyzed.Results Among 3 327 patients,1 502(45.19%)were with malignant tumors,the average dura-tion of surgery were (101.18 ±8.04)minutes;a total of 24 cases of SSI occurred,incidence of SSI was 0.72%;253 (7.60%)patients received pre-operative antimicrobial prophylaxis,62.66% used antimicrobial agents within 0.5-2 hours before surgery.The main pathogenic bacteria was Staphylococcus aureus .Univariate and logistic regression analysis re-vealed that malignant tumor,diabetes mellitus,and use of immunosuppressants were all risk factors for SSI (all P <0.05). Conclusion SSI following clean incision breast surgery under non-local anesthesia is well controlled,risk factors for SSI should be evaluated before operation,comprehensive preventive measures should be taken to reduce the incidence of SSI.

OBJECTIVE To understand the status of nosocomial infection(NI) and antibiotic use in various scale hospitals,and provide the evidence for targeted monitoring.METHODS All inpatients were requested to make a prevalence survey of NI and antibiotic use in 63 hospitals by bed-visiting and patients′ medical records checking.RESULTS Of the 34 840 patients investigated in 63 hospitals,the NI rate was 3.7%.The most common NI site was lower respiratory tract.The general ICU had the highest NI rate(35.5%).Gram-negative bacilli were the major pathogens in NI,the most common pathogen was Pseudomonas aeruginosa.The fungi accounted for 18.6%.CONCLUSIONS To effectively prevent and control NI,it should take some measures,such as enhancing the doctors′ diagnostic level of the NI,reducing the rate of NI misdiagnosis,monitoring the departments with the high NI rate,strengthening the rational antibiotic usage,and raising the pathogen detection rate.

Objective: To evaluate effects of color matching of different cavosurface margins on the resin composites in vitro.Methods:Twenty extracted human premolars with an A 2 shade buccal surface were used in this study .Rectangular shaped cavities (3.0 mm depth, 2.0 mm width, 2.0 mm length) were prepared in the center of the buccal surfaces .The gingival and occlusal cavosurface margins were prepared to be either shoulder or bevel;the other cavosurface margins remained vertical .Ten teeth were filled with Clearfil AP-X (AP), the other ten with Clearfil Majesty (MJ) and light cured.The color difference at the cavosurface margin area was measured using a spectrophotometer ( CrystalEye ) and evaluated by 3 observers subjectively .The data were statistically analyzed using repeated measures ANOVA and Chi-square test .Results:When measured by CrystalEye , the color difference between the tooth and resin composite was reduced from the center of restoration to the cavosurface margin area .Both objective and subjective evaluations showed that for AP , the color difference at the cavosurface margin area had no statistical difference among 3 types of the margins; for MJ, the color difference at bevel margin area was significantly smaller than that at the vertical margin area .Conclusion: The resin com-posite restorations produced the color matching at marginal area .The color matching of resin composites with higher diffused light transmission property is more susceptible to the type of cavosurface margins . Preparing bevels may reduce the color difference between the restoration and tooth surface .

AIM: To observe the effects of miR-542-5p on the proliferation of rat small intestine crypt epithe-lial IEC-6 cells induced by sphingosine-1-phosphate (S1P).METHODS: Two IEC-6 cell lines (SphK1-IEC-C1 and SphK1-IEC-C2) were established, which expressed sphingosine kinase-1 (SphK1) stably.Radioactive tracer was used to detect SphK1 activity and S1P secretion.The cell proliferation was observed by cell counting and described by drawing growth curve, and the cell cycle analysis was carried out by flow cytometry.The level of miR-542-5p was evaluated by RT-qPCR.RESULTS: Compared with control vector cells without SphK1 cDNA, both SphK1-IEC-C1 and SphK1-IEC-C2 cell lines showed that Sphk1 was elevated, both intracellular and extracellular S1P increased dramatically, the rate of cell growth was faster, the percentage of the cells in S phase increased, and miR-542-5p expression decreased.S1P (0.5~10 μmol/L) led to the decrease in miR-542-5p expression.On the contrary, SphK1 silencing resulted in the increase in miR-542-5p expression in the IEC-6 cells.The miR-542-5p was elevated in SphK1-IEC-C1 cells and SphK1-IEC-C2 cells, which caused the decrease in the percentage of the cells in S phase.The cell growth rate in the above-mentioned 2 cell lines decreased compared with negative control group.CONCLUSION: In IEC-6 cells, S1P promotes proliferation by inhibiting miR-542-5p expression, which induces the cell cycle transferring from G1 phase to S phase.

Objective:This study aimed to compare rectal cancer tumor volume parameters measured by MRI sequences (T1WI, T2WI, and DWI) and/or CT with those by pathological specimen. Methods:Twenty-two patients with rectal cancer were prospectively enrolled. MRI sequences including T1WI, T2WI, and DWI, and/or CT of the pelvis were performed before operation. Volume parameters, such as tumor length along the rectal axis, maximum tumor width perpendicular to rectal axis, and tumor actual area in that perpendicular plane, were measured on T1WI, T2WI, DWI, and CT, respectively, for each patient. The respective pathological parameters were further measured in surgical specimen after total mesorectal excision. The two kinds of parameter values measured in imaging and pathology were statistically compared and accuracy appraisal was performed. Results:The mean Lpath-L was 4.06±1.14 cm. The mean LT1-L, LT2-L, LDWI-L, and LCT-L were 3.91± 1.51, 4.62±1.41, 3.39±1.05, and 3.94±1.23 cm, respectively. Correlation coefficients were 0.688, 0.635, 0.688, and 0.720 (P<0.05). An average 6 mm overestimation was found in T2WI, and 1 to 6 mm underestimation in T1WI, DWI, and CT in length values compared with those measured in surgical specimen. The mean Lpath-W was 2.56 ±0.94 cm. The mean LT1-W, LT2-W, LDWI-W, and LCT-W were 3.62±0.99, 3.66±0.76, 3.23±0.58, and 3.64±1.04 cm, respectively. The magnitude of mean overestimation ranged from 5.1 to 11.1 mm. The Apath was 4.30 ±2.83 cm2. AT1, AT2, ADWI, and ACT were 8.98±3.90, 8.99±3.43, 8.41±3.09, and 9.63±4.40 cm2, respectively, which double overestimated the tumor area in the perpendicular rectal plane. Conclusion:The difference in longitudinal length between MRI sequences/CT and pathological specimen was in the range of?6 mm to 6 mm. The mean maximum tumor width and areas in the maximum tumor perpendicular plane were overestimated. This study indicated that gross tumor volume delineation based on CT or MRI for rectal cancer irradiation should be conservative in the axial images of rectum, and meticulous consideration is required along the rectum.
