Objective To study the clinical significance of combined routine ultrasound and ultrasound elastography in diagnosing thyroid microcarcinoma so as to facilitate the diagnoses of the thyroid diseases of the pilot.Methods Totally 284 thyroid nodules with the sizes less than 1 cm underwent routine ultrasound and ultrasound elastography examinations from June 2013 to June 2016.Results There were 221 benign nodules (77.8％) and 63 malignant ones (22.2％) confirmed by FNAC cytological,surgical and pathological examinations.Of the 63 malignant nodules,there were 60 cases of thyroid papillary carcinoma,one case of follicular carcinoma and two cases of medullary carcinoma.There was significant difference between the strain ratios of the benign and malignant nodules (P＜0.05),the ultrasound elastography scores of the benign nodules were statistically different from those of the malignant nodules (P＜0.05).The sensitivity,specificity and accuracy of ultrasound elastography were 90.3％,83.2％ and 86.9％ respectively when used to diagnose the thyroid nodule with the size less than 1 cm.Conclusion Routine ultrasound combined with ultrasound elastography can improve the diagnosis accuracy of small thyroid cancer,and is of great significance in early diagnosis and treatment of thyroid cancer of the pilot.

0.05). Ac-cording to the classification criteria of ARIA in 2001, 26 children suffered from intermittent A(R22 mild cases,4 moderate-severe cases),while 22 suf-fered from persistent AR(10 mild cases,12 mod-erate-severe cases). Forty percent patients with AR also had bronchial asthma. Domestic decora-tion was an important factor in the induction of AR and 27.1% of the children with AR had inher-ent predisposition. CONCLUSION The prevalence rate of AR in children aged from 9 to 10 in Nanjing is 5.1 %. Strategy of prevention and treatment of AR should beworked out according to the epidemic feature of AR.

Objective To investigate early renal damage of chronic hepatitis B (CHB) patients and the risk factors related to their renal function. Methods CHB patients who visited the second people’s hospital but did not receive systemic treatment were enrolled in our study. Those who visited for general check-up with no hepatic findings during the same period were selected as control group. Glomerular filtration rate (GFR) of all the participants were estimated by simplified MDRD equation and CKD-EPI equation (designated as M-eGFR and C-eGFR respectively). Influence factors of eGFR were statistically analyzed. Results In the total 528 cases in CHB group, 88 (16.67%) and 62 (11.74%) suffered declined M-eGFR and C-eGFR respectively. By contrast, 10 (8.77%) and 6 (5.26%) cases in the total 114 cases in control group present declined M-eGFR and C-eGFR ac?cordingly. Percentages of renal function impairment, estimated by both M-eGFR and C-eGFR, were higher in the CHB group than those in control group. The difference was statistically significant (χ2=4.518, P<0.05;χ2=4.156, P<0.05). Multiple linear regression analysis indicated that age, HBsAg and body mass index (BMI) were risk factors of M-eGFR while age, HBsAg, gender and serum albumin were risk factors of C-eGFR. On the other hand, HBV-DNA and HBeAg were not risk factors for M-eGFR or C-eGFR. Conclusion HBV infection can lead to early renal damage. Age and HBsAg are main risk factors of renal function impairment. Therefore, renal function should be scrutinized in CHB patients.

Objective To investigate the relationship between the incidence and grade of diabetic nephropathy (DN) and diabetic retinopathy (DR) in patients with type 2 diabetes mellitus. Methods A total of 154 patients with type 2 diabetes mellitus (80 males and 74 females) were investigated, ocular fundus were examined after mydriasis, at the same day, blood urea nitrogen, creatinine, glycosylated hemoglobin, blood fat, serum albumin were determined, the microalbuminuria and the glomerular filtration rate were performed. Results The incidences of DR with each stage were significantly different according to different DN stages. Univariate analyses revealed that the disorder of DR was positively correlated with the duration of diabetes, microalbuminuria, blood cholesterol (P<0.01 or <0.05), and negatively correlated with the glomerular filtration rate (P<0.01). Conclusion The incidence OFDN and DR has the highly concordance, and their lesions have some parallel relationship.

Objective To investigate the relative factors of insulin resistance(IR)during elective abdominal surgery and the mechanism of IR induced by surgery.Methods Fourteen patients underging elective abdominal surgery were studied.Fasting blood glucose(FBG),fasting plasma insulin(FPI),plasma TNF-α,IL-6 and CRP were tested for elective surgery patients on the day before,during operation and on one day after surgery.Insulin resistance index(HOMA-IR)and the index of insulin secretion(HOMA-β)were ealculated with homeostasis model assessment(HOMA).Insulin receptor and GLUT4 mRNA expression in skeletal muscle were assessed before operation and at the end of operation by use of RT-PCR.Results Significant differences were found in fasting blood glucose (5.95±1.08)mmol/L vs(8.92±2.41)mmol/L,fasting plasma insulin(19.95±3.33)mU/L vs(25.44±5.36)mU/L,IL-6(33.98±5.01)ng/L vs(45.29±7.81)ng/L and plasma TNF-α(86.70±9.27)ng/L vs(114.46±15.33)ng/L during and after operation(P＜0.01).A significant elevation of HOMA-IR levels was found after operation compared with that before operation[(9.59±2.89)vs(4.111.86)](P＜0.001).However there wag no significant difference in HOMA-β among three points(groups)of time(P=0.103).The result of RT-PCR showed that the expression of GLUT4 in muscle of patients at the end of operation reduced significantly compared with preoperation(t=12.488,P＜0.001)but there was no significance in INSR mRNA expression(P=0.165).ISI showed negative correlation with opermive time(r=-0.736、P＜0.001),blooding during operating (r=-0.594、P=0.032)and post-operative TNF-α(r=-0.641、P=0.018).Conclusion Insulin resistance occurs in elective abdominal surgery patients.The defective site is at postreceptor.To shorten the operation time,control the intensity of surgery and reduce the bleeding is helpful for decreasing IR.

Objective To evaluate the effects of sevoflurane on proteome in the cortices of neonatal rats.Methods Thirty neonatal rats at postnatal day 7 (6 rats each litter,5 litters in total) were randomly assigned into 2 groups (n =15 each):control group (C group) and sevoflurane group (S group).The rats were exposed to air and 1.8 ％ sevoflurane for 4 h in C and S groups,respectively.One rat from each litter was chosen in each group at the end of anesthesia and the puncture needle was inserted into the left ventricle via the chest wall.Arterial blood samples were then collected for blood gas analysis and for determination of blood glucose.One rat from each litter was sacrificed in each group at 3 and 72 h after the end of anesthesia,and their cortices were then dissected.Two-dimensional differential in-gel electrophoresis (2-D DIGE) was used to identify patterns of protein expression in cortices cross-labeled with different CyDyes.The differentially expressed proteins were analyzed by using matrixassisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS).Results Acid-base imbalance,anoxia or lycopenia were not found at 3 h after the end of anesthesia in both groups.The analysis showed there were 6 differentially expressed proteins at 3 h after the end of anesthesia in S group compared with C group.Among the 6 proteins,the expression of 4 proteins (class 2 c beta-tubulin,neuron-specific class Ⅲ beta-tubulin,CRMP-1 and CRMP-4) which belonged to cytoskeleton/neuronal growth proteins was down-regulated,the expression of 1 protein (ATP synthase beta subunit) which belonged to hydrolyses and transferases was down-regulated,and the expression of 1 protein (guanine nucleotide binding protein beta1) which belonged to signal transduction proteins was up-regulated (P ＜ 0.05).No significant changes in protein expression were identified at 72 h after 1.8％ sevoflurane anesthesia (P ＞ 0.05).Conclusion 1.8％ sevoflurane-induced 4 h anesthesia can induce short-time changes in the expression of proteins which are related to neuronal migration,differentiation,energy metabolism and signal transduction in cortices of neonatal rats,which may contribute to its neurodegenerative effects in brains of rats during the development period.

Objective To demonstrate the superiority and feasibility of using bioluminescent image to monitor the islet graft after islet transplantation.Methods Diabetic models were established by intraperitoneal injection of streptomycin into mature male C57BL/6 mice.Islets were harvested from the pancreas of C57BL/6 and Bclb/c mice by digestion and purification,and transfected with Lueiferase gene.The mouse diabetic models were divided into iso-transplantaion group (n=20) and allo-transplantation group (n=7).The islets of C57BL/6 were transplanted into iso-transplantaion mice with different doses (10,50,110 and 200,n=5 in every dose),and Bclb/c mouse islets were transplanted into allo-transplantation group.The islets were transplanted into the subcutaneous fat tis- sue near left scapula.The receptor mice were scanned with CCD camera to get bioluminescent images at different scheduled time points,and the changes in random blood glucose of allo-transplantation group were observed.Results On day 6 after transplantation,the scanning image showed that the pi- xel intensity from the region of interest (ROI) was increased with the increased number of islet grafts and they had a positive correlation.The random blood glucose was reduced to the normal level in the first 2 days,and then increased again to the diabetic level on 11 days averagely,while pixel intensity from the ROI reached the peak on day 6-7,and then reduced rapidly after islet transplantation in allo- transplantation group.The beginning of pixel intensity reduction occurred on day (6.14?0.90), while that of the random blood glucose raise occurred on day (10.00?0.82) after transplantation,and the former alteration occurred obviously earlier than the latter (P

Abstract?AlM:To investigate the effects of the MUC5AC levels and ocular function of the patients with glaucoma and cataract with combined surgery.? METHODS: Twenty - eight patients treated with glaucoma and cataract combined surgery were chosen as the observation group from December 2011 to June 2014 in our hospital, and other 28 cases of glaucoma and cataract did not undergo surgical treatment were selected as the control group, 30 healthy subjects were as healthy control group. the MUC5AC level and ocular surface score of the three subjects before surgery 1d, after 3 and 6mo were compared.?RESULTS: The NUC5AC of the two groups of patients was significantly lower than that of the healthy control group before surgery (P<0. 05), the ocular function score was significantly higher than the healthy control group ( P<0. 05). After 1mo, the MUC5AC of the observation group were significantly lower than that of before surgery ( P<0. 05), after 3mo MUC5AC content gradually increased to preoperative levels, after 6mo the MUC5AC were significantly higher than before surgery (P<0. 05). After 1mo, ocular function scores were significantly higher than the preoperative ( P< 0. 05 ), while after 3mo, ocular function scores decreased after 6mo of ocular surface function scores were significantly lower than the preoperative (P<0. 05). While the control group after 6mo, with the passage of time, the MUC5AC content gradually reduce, ocular function score increased gradually. ?CONCLUSlON:To treat the patients with glaucoma and cataract with combined surgery, the level of MUC5AC can temporary decrease. Ocular function score can temporary increase in, but after 3mo, it can be gradually improved.

Background and purpose:Irinotecan(CPT-11) is a derivative of camptothecin,an inhibitor of DNA topoisomerase I.CPT-11 is oxidized to inactivated metabolites(including APC)by CyP3A enzymes and activated to SN-38 by Carboxylesterase-2(CES-2).CPT-11 has been shown to exhibit excellent antitumor activity against colorectal cancer.Our research is to evaluate the efficacy and toxicity of CPT-11 combined with 5-FU/CF in the treatment of advanced or metastatic colorectal cancer.Methods:thirty-two cases of advanced or metastatic colorectal cancer patients were treated,and thirty cases were evaluable for efficacy.of which 19 cases were grouped with one cycle every two weeks and 13 cases were grouped with one cycle every three weeks.Results:In 30 evaluable patients,2 cases had complete response,11 cases had partial response,14 cases had stable disease and 3 cases with progressive disease.The response rate of the whole group was 43.3% and the stability rate was 46.7%.The clinical beneficial response rate was 83.3%.Median time to progression was 7.2 months and median overall survival time was 13.8 months.
