Objective To understand effects of hyperthyroidism on glucose metabolism and its clinical significance.Methods 65 patients admitted in Xixi Street Community Health Center were divided into 3 groups according to their accompanying disease:group A,22 cases of hyperthyroidism accompanying with diabetes mellitus,group B,23 cases of diabetes,and group C,20 cases of hyperthyroidism.Group A and B were treated with intensive insulin therapy.Group B patients took oral methimazole or propylthiouracil.Group C patients were treated with conventional treatment of hyperthyroidism.All patients were treated for three weeks.Fasting plasma glucose (FPG) and postprandial 2h plasma glucose (2hBG),heart rate,serum triiodothyronine three (TT3),serum total thyroxine (TT4)and other indicators were recorded before and after treatment.Results After intensive insulin therapy,FPG and 2h BG of patients in group A and B were controlled in ideal range.After treatment,TT3 and TT4 decreased significantly faster than before treatment(P ＜ 0.05).Patients in group A needed more insulin than in group B to bring the blood glucose to the normal level(P ＜0.05),but after three weeks,patients in group A and group B needed similar dose of insulin.Patients in group A needed more time than patients in group B to bring down the blood glucose level.(P ＜ 0.05).In addition,change of heart rate in group A before and after treatment were greater than the other two groups,and patients' heart rate in group A returned to normal after three weeks of treatment.(P ＜ 0.05).Conclusions Thyroid hormones affects glucose metabolism.Diabetes complicated with hyperthyroidism mainly caused by patient's abnormal glucose metabolism and insulin resistance.Intensive insulin therapy for these patients can improve β cell function,lower blood glucose rapidly.Compared with diabetes patient without complication of hyperthyroidism,early intensive insulin therapy should be considered.

Objective To investigate the relation between apolipoproteinC3 (-482C>T ) polymorphism and nonalcoholic fatty liver disease (NAFLD) and its clinical characteristics in the Han Chinese population. Methods Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and polyacrylamide gel electrophoresis(PAGE)were used to analyse the genotype of the apolipoproteinC3 (-482C>T) variants. Results No relation between the apolipopreoteinC3 (-482C>T) polymorphism and NAFLD was found. However, NAFLD patients carrying T allele were more susceptible to insulin resistant (IR), hypertension, hypertriglyceridemia, low levels of high-density lipoprotein cholesterol (HDL) than homozygote CC genotype. Conclusion There was no relation between the apolipopreoteinC3 (-482C>T)polymorphism and NAFLD in Han Chinese population, but T-carriers were more susceptible to metabolic disorder.

Objective To investigate the effectiveness of endovascular technique in treatment of acute arterial hemorrhage of abdominal organs.Methods Totally 159 cases (145 patients) acute arterial hemorrhage of abdominal organs were enrolled.All patients underwent emergency transarterial angiography.Endovascular treatment by spring coil,gelatin sponge,or covered stent were in 40 cases.The success rate of immediate and long-term hemostasis was judged by the postoperative radiography,symptoms and the changes of vital signs and laboratory results.Results The positive signs in angiography were observed in 47 among the total 159 cases (47/159,29.56％).Seventy-seven postoperative hemorrhage cases underwent angiography and 29 cases (29/77,37.66 ％) were positive,82 non-operative hemorrhage cases underwent angiography and 18 cases (18/82,21.95％) were positive.The difference was statistical significant (P＜0.05).Endovascular treat ment were performed in 40 cases (33 by spring coils,4 by gelatin sponge and 3 by covered stent).Hemorrhages were con trolled immediately in all the 40 cases after embolization and the success rate were 100％.Conclusion Endovascular tech nique is minimal invasive,and it is an effective method for treatment of acute arterial hemorrhage in abdominal organs.

Objective To study the correlation of fecal calprotectin and lactoferrin with intestinal mucosa lesions in Crohn′s disease (CD). Methods Eighty-eight cases of diagnosed CD patients were selected as study group and 35 irritable bowel syndrome (IBS) patients were as controls. Fecal samples of CD patients were collected in one week before colonoscopy examination and of IBS patients were collected of CD patients, CD activity index (CDAI) was calculated at same visit, and CD endoscopic index (CDEI) was calculated in the subsequent endoscopic examination. The level of fecal calprotectin and lactoferrin were tested by ELISA method. Results The median levels of facal calprotectin and lactoferrin in CD patients were 277.16 mg/kg (from 96.85 to 693.57 mg/kg) and 59.68 mg/kg (from 10.75 to 100.58 mg/kg) respectively, which were significantly higher than those of IBS patients (7.6mg/kg, from 5.54 to 32.3 mg/kg and 0.65 mg/kg from 0.23 to 4.34 mg/kg), (Z=-8.301 and -7.986, respectively both P =0.000). There were no significant difference of calprotectin and lactoferrin level between CD patients with colon pathological changes and without colon pathological changes (Z=-0.424 and -0.699,P=0.672 and 0.485, respectively). There was no significant difference of calprotectin and lacoferrin level between remission and active periods in CD patients (Z=-1.491 and -1.075, P=0.136 and 0.283, respectively). The median values of calprotectin and lactoferrin of patients in moderate and severe active period judged under endoscopy were 663.11 mg/kg (from 263.45 to 2015.63 mg/kg) and 105.64 mg/kg (from 56.52 to 187.44) mg/kg respectively, in mild active period were 344.54 mg/kg (from 132.03 to 722.67 mg/kg) and 86.68 mg/kg (from 21.07 to 100.55 mg/kg) accordingly, and in remission period were 133.94 mg/kg (from 60.54 to 583.33 mg/kg) and 45.31 mg/kg (from 7.59 to 48.31 mg/kg, respectively). Both calprotectin and lactoferrin levels were significantly higher in active period than in remission period (χ2=10.63 and 8.18, while, P=0.005 and 0.017, respectively). Conclusions The level of fecal calprotectin and lactoferrin can reflect the pathological changes and severity of the intestinal mucosa.

Objective: To learn the genotypic drug resistance of men who have sex with men ( MSM ) with HIV who failed in antiviral therapy in Yunnan Province, in order to provide basis for improving the effect of antiviral therapy. Methods: The patients who were infected with HIV-1, homosexual transmitted and failed in antiviral therapy in Yunnan Province from 2014 to 2019 were recruited. Their plasma samples were tested by reverse transcription nested polymerase chain reaction ( RT-nPCR ) , the fragments were spliced using ContigExpress, and the resistance to 8 protease inhibitors ( PIs ) , 7 nucleoside reverse transcriptase inhibitors ( NRTIs ) and 5 non-nucleoside reverse transcriptase inhibitors ( NNRTIs ) were obtained from the HIV drug resistance data website of Stanford University. Results: A total of 205 HIV/AIDS cases were included, 169 positive plasma samples were amplified, 112 cases were drug resistant, and the rate of drug resistance was 66.27%. The patients who were aged 30-49 years ( 76.09% ) , had genotype of CRF01_AE ( 76.34% ) or treated by AZT+3TC+NVP ( 77.08% ) had higher resistance rate. The resistance rates of NNRTIs, NRTIs and PIs were 62.72%, 49.70% and 2.96%, respectively; the resistance rates of NVP and EFV in NNRTIs were 62.72% and 61.54%. The main mutation site associated with NNRTIs was K103, accounting for 21.89% ( 37 cases ) ; the main mutation site associated with NRTIs was M184, accounting for 39.64% ( 67 cases ) ; the main mutation sites associated with PIs were M46L/K, accounting for 2.96% ( 5 cases ) , resulting in high resistance to NFV. Conclusions The drug resistance rate of HIV-infected MSM with failure of antiviral therapy in Yunnan Province is relatively high, with CRF01_AE as the main gene subtype of drug resistance. The drug resistance rate of NNRTIs is relatively high, especially NVP and EFV.

Objective To evaluate the long-term efficacy of antiretroviral therapy and drug resistance among human immunodeficiency virus-1(HIV-1)-infected children in Yunnan.Methods In this retrospective study,CD4+T cell counts,HIV viral loads and genetic drug resistance results were obtained from HIV-1-infected children who were treated with antiretroviral treatment between January 2004 to July 2015.Results A total of 1 078 HIV/acquired immune deficiency syndrome(AIDS)children were treated with antiviral therapy.Before treatment,the average CD4+cell number was(466.8 ± 397.2)cells/μL. The percentages of children with CD4+cell count >750 cells/μL after 1-year,3-year,5-year and 8-year treatment were 54.31%,62.87%,68.46% and 74.19%,respectively.Virological failure occurred in 150 HIV/AIDS children(13.9%),and the virological failure rate was 4.3/100 child-years.Among those 150 patients with virological failure,104 cases(69.33%)exhibited genetic resistance to antiretroviral drugs.The prevalent mutations associated with drug resistance were M 184V/I(75.0% [78/104]), K103N(43.3%[45/104]),G190A(29.8%[31/104]),Y181C(22.1%[23/104]),T215Y/F(20.2%[21/104]).Conclusions After long-term antiretroviral treatment,most of the HIV-infected children have restored the immunity and suppressed HIV viral replication successfully.HIV resistance is the main cause of virological failure.Drug resistance mutations mainly occur in nucleoside reverse transcriptase inhibitor and non-nucleoside reverse transcriptase inhibitor,and the resistance rate of proteinase inhibitor is low.Early genetic resistance testing and switch to second-line therapy will improve the treatment outcome.

Objective To investigate the effect of catheter-based peripheral sympathetic denervation (CPSD) on peripheral artery sympathetic tone of New Zealand rabbits.Methods Twenty New Zealand rabbits were randomly divided into CPSD group and control group (each n =10).Endovascular radiofrequency ablation above the bifurcation of the abdominal aorta was performed on the rabbits in CPSD group.Norepinephrine was infused with continuous trans-arterial pumping in both two groups.And laser Doppler flowmetry was used to measure the peripheral microperfusion and temperature of right hindlimb of rabbits.The changes of the peripheral microperfusion and temperature before (resting state) and after norepinephrine infused (norepinephrine load state) were compared between the two groups.Results Eight rabbits completed the procedure in each group.The change of peripheral microperfusion between resting and norepinephrine load states in CSPD group was lower than that in control group ([-37.19±22.56]％ vs [-57.02％±10.12]％,P=0.04),whereas the change of temperature was not significantly different between the two groups ([0.35±0.50]℃ vs [-0.21± 1.83]℃,P=0.43),while significant difference was noticed when two rabbits with abnormal temperature change in control group were neglected ([0.34± 0.50] ℃ vs [-1.14 ±0.72] ℃,P＜0.01).Conclusion CPSD can be used to decrease the peripheral artery sympathetic tone of New Zealand rabbits,and may play an important role in relieving symptoms of critical limb ischemia.

Objective To analyze the genetic structure and recombination characteristics of a new-ly discovered HIV-1 unique recombinant strain in Yunnan Province. Methods During a test for drug-resist-ant HIV genotypes in Yunnan Province in 2016, a recombinant fragment was found in the pol region of a HIV-1 strain isolated from a patient. Two overlapping segments of the HIV-1 genome were amplified by RT-PCR, and then the products were sequenced. Recombination analysis was performed using RIP, jpHMM and SimPlot3. 5 software. A phylogenetic tree was constructed for homology analysis by Neighbor-joining method using MEGA6. 06 software. Results A nearly full-length HIV-1 gene sequence with 8590 bp in length was obtained. Breakpoint analysis indicated that the sequence consisted of CRF01_AE and fragments of B and C subtypes. CRF01_AE was used as the backbone with B and C subtype fragments inserted. The positions were 791 to 1171 for CRF01_AE, 1172 to 2652 for C subtype fragment, 2653 to 2977 for B subtype frag-ment, and 2978 to 9380 for CRF01_AE using HIV-1 HXB2 as the reference strain. Conclusions Some new strains formed by cross-recombination of CRF01_AE and B and C subtypes were discovered in Yunnan Province in recent years. It was found that the recombination pattern of the newly discovered strain was com-plex, suggesting that close attention should be paid to the changes in epidemic trends, which was of great im-portance to understand the current prevalence and epidemic trends of HIV-1.

Objective To observe the clinical value of cone-beam computed tomography (CBCT) combined with iGuide system in percutaneous transthoracic needle biopsy (PTNB) of pulmonary lesions.Methods A total of 30 patients with solitary lung lesion underwent PTNB procedures were enrolled.The needle path was planned with iGuide system and 3D CT-like MPR images after CBCT.A coaxial system with 18-gauge cutting needle was used for biopsy.Procedure related data,complications and radiation exposure of patients were recorded.Results Among 30 patients,malignant lesions were found in 24,and benign lesions were in 6 patients.On PTNB,28 patients were correctly diagnosed,1 case was with insufficient samples but obtained correct pathologic result with second biopsy,1 case was false-negative finding.The diagnostic accuracy,sensitivity,specificity,positive predictive value and negative predictive value of PTNB in diagnosis of lung diseases was 96.67％ (29/30),96.00％ (24/25),100％ (5/5),100％ (24/24) and 83.33％ (5/6),respectively.The mean procedure time was (13.03+3.61)min,and exposure dose was (7.95+4.57)mSv.After PTNB procedures,pneumothorax and hemoptysis occurred in 6 (6/30,20.00％) and 3 (3/30,10.00％) patients,respectively.Conclusion CBCT combined with iGuide system for guiding PTNB is accurate and safe with reasonable radiation exposure.

Objective To investigate the influence factors of mortality among human immunodeficiency virus (HIV)-infected children under highly active antiretroviral therapy (HAART).Methods Retrospective cohort study of 652 children initiated HAART from 2005 to 2014 was conducted,and enrolled patients were followed-up until December,2015.Survival data was analyzed using Kaplan-Meier method and Cox regression model was used to identify independent predictors of mortality among these children on HARRT.Chi-square test and Fisher's exact test were used for comparison between groups.Results Overall,26 of the children died over a follow-up period of 3 116.24 child-years,with a mortality rate of 0.83 per 100 child-years.Twelve (46％)of deaths occurred during the first six months after starting HAART.Cox regression analysis of variables showed that the World Health Organization (WHO) clinical stages Ⅲ/Ⅳ (hazard rate [HR] =10.717,95％confidence interal [95％ CI]:4.189-4.749,P =0.000),baseline hemoglobin ＜ 80 g/L (HR =14.768,95 ％ CI:5.721-38.125,P =0.000),tuberculosis co-infection (HR =4.794,95％ CI:2.105-10.918,P =0.000),baseline CD4+T lymphocyte ＜ 50 cells/μL (HR =4.219,95％ CI:1.524-11.680,P =0.006),weight-for-age z-score ＜-2 (HR =2.983,95 ％ CI:1.094-8.135,P =0.033) were independently associated with death,whereas the age ＜ 7 year-old at HAART initiation was protectire (HR =0.293,95％ CI:0.126-0.684,P =0.005).Conclusions The mortality of children receiving HAART is strongly associated with WHO stages Ⅲ/Ⅳ,hemoglobin ＜ 80 g/L,weight-for-age z-score ＜-2,tuberculosis co-infection and older age at treatment.
