ABSTRACT
Objective:To learn about the levels of serum iodine and thyroid function indicators in adults with normal thyroid function in Liaoning Province, to establish the medical reference value range of serum iodine, and to explore the relationship between serum iodine and thyroid function indicators.Methods:From February 2017 to December 2018, one subdistrict and one rural township were selected as the survey sites in the coastal area (Gaizhou City of Yingkou) and inland area (Kangping County of Shenyang) of Liaoning Province, respectively. Permanent residents aged 18 and older who have lived there for 5 years or more were selected as the survey subjects. Blood samples were collected to test the levels of serum iodine and thyroid function indicators [thyroid stimulating hormone (TSH), free triiodothyronine (FT 3), free thyroxine (FT 4), thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb)]. The percentile method was used to establish the 95% medical reference value range of serum iodine in adults with normal thyroid function, and Pearson correlation analysis was used to analyze the correlation between serum iodine and thyroid function indicators. Results:A total of 1 621 adults with normal thyroid function were examined, the median serum iodine was 62.0 μg/L, and the 95% medical reference value range was preliminarily determined as 37.0-103.0 μg/L. Among them, the medians serum iodine of males and females (826 and 795 cases) were 62.3 and 61.0 μg/L, respectively, and there was no significant difference between genders ( Z=- 1.26, P = 0.210). The medians serum iodine of adults in coastal and inland areas (827 and 794 cases) were 61.7 and 61.9 μg/L, respectively, and there was no significant difference between areas ( Z = - 0.16, P = 0.870). The medians serum iodine of adults aged 18 - 29, 30 - 39, 40 - 49, 50 - 59 and 60 - 80 (385, 392, 378, 253 and 213 cases) were 61.0, 61.0, 63.0, 65.0 and 62.0 μg/L, respectively, and the difference between ages was statistically significant ( H = 14.52, P = 0.006). Pearson correlation analysis showed that serum iodine was weakly correlated with the level of FT 4 ( r = 0.17, P < 0.001), but not with the levels of TSH, TPOAb and TgAb ( P > 0.05). Conclusions:This study has established the medical reference value range of serum iodine in adults with normal thyroid function in Liaoning Province. Serum iodine is not correlated with the levels of TSH, TPOAb and TgAb.

A total of 30 DSMs (12 DSMs were up-regulated and 18 DSMs were down-regulated) in a dynamic process (6 h∶12 h) after HRV1B infection. Unknown metabolites took up most proportions. The trends of fatty acid, lipid, amino acid, nucleotide and carbohydrate were increased along with the prolonging of HRV1B infection. DSMs such as Diisononyl phthalate was co-detected DSMs among three groups.Conclusions:Metabolites such as fatty acid, lipid, amino acid, nucleotide and carbohydrate of BEAS-2B cells are changed induced by HRV1B infection.
ABSTRACT
Objective:To evaluate the effectiveness and safety of transepithelial photorefractive keratectomy (TransPRK) assisted by smart pluse technology (SPT) for the correction of high myopia.Methods:An observational case series study was conducted.Sixty high myopic patients (107 eyes) with spherical equivalent (SE)≥-6.0 D who received TransPRK assisted by SPT from January to December 2016 in Eye Hospital of Wenzhou Medical University were enrolled.Uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) of the patients were examined and recorded in logarithm of the minimum angle of resolution (LogMAR) units, and refraction was examined with a subjective refractometer.The healing of corneal epithelium and corneal haze was observed with a slit lamp.Intraocular pressure (IOP) was measured with the non-contact tonometer.Safety index (SI) and efficacy index (EI) were analyzed.The follow-up time was 12 months.This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Eye Hospital of Wenzhou Medical University (No.2019-197-k-177). Written informed consent was obtained from each patient prior to any medical examination.Results:The mean epithelial healing time was (3.77±1.02) days.There were statistically significant differences in UCVA and BCVA between before and after surgery ( Z=380.812, 267.313; both at P<0.001). And the 7-day, 6-month, and 12-month postoperative BCVA were better than preoperative BCVA, showing statistically significant differences (all at P<0.05). Mean SI was 1.10±0.12, and mean EI was 1.05±0.17 at 12 months after surgery.There was no significant difference between the attempted SE before surgery (-8.02±1.36)D and the achieved SE at 12 months after surgery (-8.04±1.51)D ( P=0.523). SE in the predictive range within ±0.50 D accounted for 79% (85/107) and that within ±1.0 D accounted for 92% (98/107). The IOP was slightly increased in 3 eyes at 7 days and 7 eyes at 1 month after surgery, respectively, which returned to normal after the use of ophthalmic solution for lowing IOP.The incidence of haze severer than grade 1 was less than 1% (1 eye), and haze gradually disappeared after application of drugs. Conclusions:TransPRK assisted by SPT for high myopia shows good safety, effectiveness and predictability.It is an ideal corneal surface surgery to correct high myopia.

The method of acupuncture combined with rehabilitation training in the treatment of shoulder hand syndrome after stroke is reliablet, quick, with simple operation and less adverse reactions. Among them, characteristic acupuncture could focus on the targeted points with obvious effect than ordinary acupuncture, and the combination with rehabilitation training could greatly improve the curative effect. However, there still exist some problems in the current research, such as the difficulty of conducting blind clinical trials of acupuncture therapy; the lack of follow-up data in the evaluation of curative effect, the uncertainty of long-term curative effect; the small sample size of clinical research, etc., so multi-centered and large sample RCT research are still needed.

ABSTRACT
Objective To deduce the normal range of thyroglobulin ( Tg ) of adults senum in Liaoning Province . Methods From February to November 2017 , in Kangping County of Shenyang ( inland group ) and Gaizhou City of Yingkou (coastal group), the Tg levels of adults in different age groups were investigated according to the cluster stratified sampling method. Adults were divided into young (18 - 44 years old), middle (45 - 59 years old ) , and elderly (≥60 years old ) groups , and fasting blood samples were collected . Levels of Tg , thyroid function [ thyroid stimulating hormone (TSH), free triiodothylaminogenic acid (FT3), free thyroxine ( FT4 ) ] , thyroglobulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) were determined by automatic electrochemiluminescence immunoassay analyzer. Statistical analysis was performed on Tg measured values of normal thyroid function and antibody-negative adults, and the percentile range (P2.5 - P97.5) was used to calculate the 95％ normal range of both sides. Results A total of 685 adults were included, with a Tg level of 9.86 μg/L, including 333 adults in the inland group with a Tg level of 8.97 μg/L, and 352 adults in the coastal group with a Tg level of 10.44 μg/L. There were 255 males and 430 females, Tg levels were 9.39 and 9.99 μg/L, respectively. There were 179, 307 and 199 adults in the young, middle and elderly groups, Tg levels were 8.84, 9.22, and 11.73 μg/L, respectively, the differences were statistically significant (H=9.607, P<0.05). The normal range of Tg in adults was 1.23-58.63μg/L, and the normal ranges of Tg in the young, middle and elderly groups were 1.62 - 41.90, 0.99 -54.58, and 0.94 - 85.78 μg/L, respectively.

ABSTRACT
The aim of this study was to investigate the inhibitory effect and the underlying mechanism of ethacrynic acid (EA) on the contraction in mice. BL-420S force measuring system was used to measure the tension of mouse tracheal rings. The whole cell patch clamp technique was utilized to record the channel currents of airway smooth muscle (ASM) cells. The calcium imaging system was used to determine the intracellular Ca concentration ([Ca]) in ASM cells. The results showed that EA significantly inhibited the high K (80 mmol/L) and acetylcholine (ACh, 100 µmol/L)-induced contraction of mouse tracheal rings in a dose-dependent manner. The maximal relaxation percentages were (97.02 ± 1.56)% and (85.21 ± 0.03)%, and the median effective concentrations were (40.28 ± 2.20) μmol/L and (56.22 ± 7.62) μmol/L, respectively. EA decreased the K and ACh-induced elevation of [Ca] from 0.40 ± 0.04 to 0.16 ± 0.01 and from 0.50 ± 0.01 to 0.39 ± 0.01, respectively. In addition, EA inhibited L-type voltage-dependent calcium channel (LVDCC) and store-operated calcium channel (SOCC) currents in ASM cells, and Ca influx. Moreover, EA decreased the resistance of the respiratory system (Rrs) in vivo in mice. These results indicated that EA inhibits LVDCC and SOCC, which results in termination of Ca influx and decreases of [Ca], leading to relaxation of ASM. Taken together, EA might be a potential bronchodilator.

OBJECTIVE: To investigate the diagnostic value of diffusion kurtosis imaging (DKI) histogram analysis in hepatic fibrosis staging. MATERIALS AND METHODS: Thirty-six rats were divided into carbon tetrachloride-induced fibrosis groups (6 rats per group for 2, 4, 6, and 8 weeks) and a control group (n = 12). MRI was performed using a 3T scanner. Histograms of DKI were obtained for corrected apparent diffusion (D), kurtosis (K) and apparent diffusion coefficient (ADC). Mean, median, skewness, kurtosis and 25th and 75th percentiles were generated and compared according to the fibrosis stage and inflammatory activity. RESULTS: A total of 35 rats were included, and 12, 5, 5, 6, and 7 rats were diagnosed as F0–F4. The mean, median, 25th and 75th percentiles, kurtosis of D map, median, 25th percentile, skewness of K map, and 75th percentile of ADC map demonstrated significant correlation with fibrosis stage (r = −0.767 to 0.339, p < 0.001 to p = 0.039). The fibrosis score was the independent variable associated with histogram parameters compared with inflammatory activity grade (p < 0.001 to p = 0.041), except the median of K map (p = 0.185). Areas under the receiver operating characteristic curve of D were larger than K and ADC maps in fibrosis staging, although no significant differences existed in pairwise comparisons (p = 0.0512 to p = 0.847). CONCLUSION: Corrected apparent diffusion of DKI histogram analysis provides added value and better diagnostic performance to detect various liver fibrosis stages compared with ADC.

@#AIM: To investigate the effect of soft corneal contact lens on the recovery of corneal epithelial defects and the comfort in patients with diabetic retinopathy after vitrectomy. <p>METHODS: Twenty patients(20 eyes)with diabetic retinopathy whose corneal epithelium defected after vitrectomy were randomly divided into 2 groups. The trial group(10 eyes)received the combination treatment of wearing soft corneal contact lenses and eyedrops to promote corneal epithelial repair, and the control group(10 eyes)only received eyedrops. The corneal epithelial healing time was observed postoperatively. And the scores of the comfort in patients between two groups were compared. <p>RESULTS: The average duration of corneal epithelial defects was 4.1±1.20d in the trial group, and 14.2±6.07d in the control group, which was statistically significant different between the two groups(<i>P</i><0.05). After treatment, the patients in the trial group felt more comfortable compared with the ones in the control group. There was no significant statistical difference about the scores of the comfort between the two groups at postoperative 3mo(<i>P</i>>0.05). <p>CONCLUSION: The soft corneal contact lens could effectively treat patients with corneal epithelial defects after vitrectomy, and improve their comfort.
ABSTRACT
Objective: To assess the trends in clinical characteristics, treatment, and outcomes for hospitalized patients undergoing percutaneous coronary intervention (PCI) in central-western urban hospitals of China in 2001, 2006 and 2011. Methods: We used a 2-stage, random sampling strategy to create a Chinese central-western urban hospital representative sample of 2152 patients undergoing PCI at 26 hospitals in China PEACE- retrospective CathPCI study and calculated the weighted data of clinical information in each year. Results: Between 2001 and 2011, the admission rate for PCI increased by 46 folds. Compared with 2001, the patients undergoing PCI were more likely to be female, older than 80 years, and to have history of diabetes, dyslipidemia and PCI in 2011. The proportion of trans-radial PCIs increased from 3.5% in 2001 to 87.6% in 2011 (Ptrend < 0.0001); the proportion of drug eluting stents (DES) among all the implanted stents increased from 16.4% in 2001 to 95.7% in 2011 (Ptrend < 0.0001), largely due to increased use of domestic DES. Less than 5% of medical record of admission for PCI documented door time and balloon time. The median length of stay decreased from 13 days in 2001 to 10 days in 2011 (Ptrend < 0.0001). In-hospital mortality did not change signiifcantly, but both any bleeding and access bleeding events were decreased signiifcantly over time (Ptrend < 0.05). Conclusion: There has been a rapid increase in the volume and significant change in treatment patterns of PCI over the 10-year period from 2001 to 2011 in Chinese central-western urban hospitals. We identiifed quality gaps that represent opportunities to improve medical care.
ABSTRACT
Objective: To explore the application and affecting factors of clopidogrel loading therapy in patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) in china in 2006 and 2011. Methods: Based on “China patient-centered evaluative assessment of cardiac events retrospective study of acute myocardial infarction”, we collected clinical information of STEMI patients with PCI in 2006, 2011 and analyzed clopidogrel loading therapy status in different years and different hospitals. According to clopidogrel doses, the patients were divided into 2 groups: Clopidogrel 300mg group, the patients received a single dose of clopidogrel ≥300mg while 0.05. In 2006, the hospital median rate of clopidogerl application was 44.4% (IQR 21.8% to 69.0%) and in 2011, it was 48.1% (IQR 25.0% to 70.8%),P=0.940. Binary logistic regression analysis showed that the patients were admitted within 12 hours of onset, with primary PCI and treated in central region had the higher rates of clopidogrel loading therapy. Conclusion: Clopidogrel loading therapy was seriously inadequate in STEMI patients with PCI, variation was across hospitals and the status was similar between 2006 and 2011. Clopidogrel loading therapy should be improved.
ABSTRACT
Objective To investigate the correlation between ultrasound-guided diffuse optical tomography (US-DOT) and hypoxia-inducible factor-1Α (HIF-1Α) of breast cancer. Methods Totally 69 patients with pathologically confirmed breast cancer underwent preoperative conventional breast ultrasonography examinations and US-DOT at Peking Union Medical College Hospital From October 2007 to February 2010 were enrolled in this study.After surgery,immunohistochemical staining of HIF-1Α and CD34 were performed,and the differences of total hemoglobin concentration (THC) and microvessel density (MVD) between HIF-1Α positive and negative groups were analyzed. Results HIF-1Α was positive in 12 cases (17.4%) and negative in 57 cases (82.6%). The average THC and MVD of HIF-1Α-positive cases were (274.763±77.661) Μmol/L and (33.8±10.8)/0.2 mm(2) respectively. The average THC and MVD of HIF-1Α-negative cases were (228.059±65.760)Μmol/L and (28.4±7.4)/0.2 mm(2). MVD(t=2.049,P=0.04) and THC(t=2.167,P=0.034) of HIF-1Α-positive group were significantly higher than those of HIF-1Α-negative group. Conclusions HIF-1Α can promote tumor angiogenesis and thus increase the blood supply and THC. As an indicator of tumor blood supply,THC can indirectly reflect the angiogenic activity of breast cancer.

ABSTRACT
<p><b>OBJECTIVE</b>To investigate the value of ultrasound in the diagnosis of pseudomyxoma peritonei (PMP) and summarize the ultrasonographic features of PMP by comparing with computed tomography (CT) findings.</p><p><b>METHOD</b>Ultrasound and CT scan results of 25 patients with PMP confirmed by pathology after surgery were analyzed retrospectively.</p><p><b>RESULTS</b>Among these 25 PMP patients,three were diagnosed by ultrasound and six by CT(P=0.579). The specific ultrasonographic features of PMP were as follows:the dense punctuate echoes or floccules were detected in hydrops abdominis,which seldom or never move with the change of body position. Honeycomb-like lesions were typical. Notches were formed on the surface of liver or spleen due to the mucinous material and/or the mucinous lesions.</p><p><b>CONCLUSIONS</b>Both ultrasound and CT scan have poor detection rate in the diagnosis of PMP. PMP has specific ultrasonographic features,which may make it possible to diagnose most PMP lesions by ultrasound before surgery</p>
