Objective To evaluate the iodine nutritional condition among populations in Aksu after implementing free iodized salt in population of Xinjiang.Methods According to the National Iodine Deficiency Monitoring Programme (Revised),totally 45 villages (towns) of subordinated 8 counties and Aksu City,Xinjiang were selected for collecting salt samples.Meanwhile,in 27 villages (towns) primary schools,school-aged children (8-10 years old) were selected for collecting disposable urine samples,B ultrasound was used to check thyroid volume and intelligence (IQ) was evaluated by China Combined Raven Test (CRT).Pregnant women were sampled for collecting their disposable urine near the primary schools.Both the children and pregnant women were evaluated the iodine deficiency disorders (IDD) knowledge awareness by questionnaire.The urine iodine concentration was measured by the ammonium persulfate digestion-As-Ce catalytic spectrophotometer method.The salt iodine concentration was measured by the direct titrimetric method,and other kinds of iodine in salt were measured by referee method (GB/T 13025.7-2012).Results A total of 2 700 household salt samples were collected,the average of iodine concentration in household salt was (26.95 ± 5.10) mg/kg.The coverage of household iodized salt was 98.56％ (2 661/2 700).The coverage of edible iodized salt was 98.00％ (2 646/2 700).A total of 2 159 urine samples were collected,the median of urine iodine concentration (UIC) among school-aged children (8-10 years old) was 235.50 μg/L.The total goiter rate was 1.51％ (33/2 179) among children aged 8-10 years old.A total of 2 098 people were conducted IQ test,the average IQ was 88.03 ± 17.14.A total of 1 047 urine samples were collected,the median of UIC among pregnant women was 213.50 μg/L.The IDD knowledge awareness rate of children and women were 98.82％ (751/760) and 99.23％ (258/260),respectively.Conclusions The iodine nutrition is in an adequate range,awareness of IDD prevention is obviously improved among children which is representative of common people and pregnant women after implementing the free iodized salt in population of Xinjiang in Aksu.The policy of preventing IDD based on this policy has showed enormous effect.

To explore the mechanism of the absorption enhancement of Angelica dahurica extract (Ade), the absorption mechanism of baicalin in the Scutcllaria water extraction as well as the effect of Angelica dahurica extract on absorption of baicalin were investigated. In order to determine the main absorption site, everted intestinal sac model was used to study the effect of Angelica dahurica extract on the absorption of baicalin at duodenum, jejunum, ileum and colon. In situ single pass intestinal perfusion model was performed to study the absorption of various concentrations of baicalin and the effect of Angelica dahurica extract on the absorption of baicalin at the main absorption site. To authenticate the consequence of perfusion by getting the blood from the hepatic portal vein and determine the concentration of the baicalin in the blood. The result showed that baicalin could be absorbed at all of the four intestinal segments with increasing absorption amount per unit as follows: ileum > colon > jejunum > duodenum. The absorption ofbaicalin in the duodenum significantly increased with Angelica dahurica extract, thus, duodenum was chosen to be the studying site. Apparent permeability values (Papp) and absorption rate constant (Ka) of baicalin in the duodenum increased gradually with higher concentrations. When the concentration of baicalin rises to a certain degree, the absorption increase had a saturable process, the absorption of baicalin may be an active transportation. Baicalin may be not a substrate of P-gp as verapamil which had not significantly affected the Papp and Ka of baicalin. The absorption of baicalin in the duodenum significantly increased (P < 0.01) in the two models with Angelica dahurica extract and the concentration of baicalin in the blood from the hepatic portal vein showed that the Angelica dahurica extract can increase the absorption of baicalin.

BACKGROUND: The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS: The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS: Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87％ in the ENOTES group, which was statistically different from 78.12％ in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION: Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.

OBJECTIVE: The aim of the study was to compare transcatheter arterial chemoembolization (TACE) plus ¹³¹I-labelled metuximab with TACE alone for hepatocellular carcinoma (HCC). MATERIALS AND METHODS: A comprehensive search was conducted in PubMed, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Chinese BioMedical Literature Database with published date from the earliest to February 29th, 2016. No language restrictions were applied, but only prospective randomized controlled trials (RCTs) or non-RCTs were eligible for a full-text review. The primary outcome was the overall survival (OS) and effective rate (the rate of partial atrophy or complete clearance of the tumor lesion). The odds ratios (ORs) were combined using either the fixed-effects model or random-effects model. RESULTS: Eight trials (3 RCTs and 5 non-RCTs) were included, involving a total of 1121 patients. Patients receiving combined therapy of TACE plus ¹³¹I-labelled metuximab showed significant improvement in effective rate {OR = 4.00, (95% confidence interval [CI]: 2.40–6.66), p < 0.001}, 1-year OS (OR = 2.03 [95% CI: 1.55–2.67], p < 0.001) and 2-year OS (OR = 2.57 [95% CI: 1.41–4.66], p = 0.002]. CONCLUSION: TACE plus ¹³¹I-labelled metuximab is more beneficial for treating advanced HCCs than TACE alone in terms of tumor response and OS. Large, multi-center, and blinded randomized trials are required to confirm these findings.
