Objective To investigate the iodine nutritional level of 5 special groups (newly married women,pregnant women, lactating women, babies and infants, and students) in Ningxia, and to provide the basis for formulating prevention and control strategies. Methods Clustering and random sampling method were used. In 2008 and 2009, in the 22 counties investigated, in every county with 9 townships or more, nine townships were randomly selected according to their sub-area positions of east, west, south, north and center; four villages were randomly selected in each chosen township, four people with special needs and 2 infants were randomly selected for urine samples collection in each chosen village. In every county with 9 or less townships, one township was randomly selected respectively in east, west, south, north and center sub-areas; four villages were randomly sampled in each chosen township, eight people with special needs and 3 infants' urine samples were randomly collected in each chosen village. In the 22 counties, one township was randomly selected respectively in east, west,south, north and center sub-areas, one village elementary school was randomly sampled in each chosen township,twenty students aged 8 - 10 were randomly selected to collect their urine samples in each school. The iodine concentration was determined by arsenic-cerium contact method. Results A total of 6894 copied of urine samples from newly married women, pregnant women, lactating women, babies and infants, and students were examined, the urinary iodine medians were 209.3, 187.4, 184.0, 216.5, 216.3 μg/L, respectively. From low to high in the order was lactating women, pregnant women, newly married women, students, babies and infants. The level of urinary iodine of babies and infants, pregnant women and lactating women were appropriate, the one of newly married women and students were higher than appropriate. The proportion of less than 100 μg/L of urinary iodine of the 5 kinds special groups were 11.1% (53/475), 35.4% (308/871), 35.4% (659/1863), 19.1% (283/1483), 8.4%(185/2202), respectively, while the urinary iodine of the pregnant women and lactating women were relatively high. The urinary iodine medians of the 5 special groups were also very different among counties. Conclusions The urinary iodine of the 5 special groups in Ningxia presents obvious differences between populations and regions.Current iodized salt is sufficient to ensure iodine nutrition needs for the 5 special groups. But married women and students have higher levels of iodine nutrition, indicating that the salt iodine concentration of Ningxia residents have cut space, full consideration of the 5 special groups and regional differences should be taken.

Objective The aim of this study is to analyze the long-time outcome of hepatocellular carcinoma(HCC)patients with micro-vascular invasion underwent liver resection combined with transarterial chemoembolization(TACE).Methods Our database of surgical re-section from January 2009 to September 2015 was retrospectively analyzed.This study was conducted on 296 HCC patients with MVI.Patients were divided into two groups:one group underwent liver resection (n =159)and another for liver resection combined with TACE (n =137). The 5-year overall survival rate (OS)and disease free survival (DFR)were compared.A multivariate Cox proportional hazards regression a-nalysis was performed to assess the prognostic risk factors associated with overall survival rate.Results The 5-year OS and 5-year DFR see significant difference (OS:18% vs.8%,P =0.001;TRF:15% vs.8%,P =0.008).Multivariate analysis revealed that HBsAg(HR 1.596, P =0.002,95% CI 1.194 ~2.131),tumor size >5 cm(HR 0.729,P =0.042,95% CI 0.539 ~0.989)as well as multiple tumors(HR 1.480,P =0.049,95% CI 1.002 ~2.186)were correlated to poor overall survival rate.Conclusion Surgical resection combined TACE for HCC patients with MVI realized a better prognosis than patients merely underwent therapy of resection.

Abstract: Mycobacterium senegalense is one of the major pathogens causing bovine farcy, and reports of its infection in
human are rare. Here is a report on a woman who had been taking hormones and immunosuppressants for a long time for SLE
and underwent abdominal soft tissue infection with Mycobacterium senegalense after abdominal liposuction, to provide reference
for clinical diagnosis and treatment. The patient, female, 32 years old, has a history of SLE for more than 2 years, and currently
takes "methylprednisolone, hydroxychloroquine, and mycophenolate mofetil" regularly. Nine months before the patient was
admitted to the hospital, she once performed abdominal, waist and buttock liposuction in a medical beauty institution. One
month after the operation, several masses gradually appeared on the abdominal wall, accompanied by tenderness, one of the
masses had obvious fluctuation on palpation and purulent fluid could be drawn out. The location of the abdominal wall mass
was consistent with the insertion site of the liposuction needle. After the onset of the disease, the patient went to the medical
beauty institution for puncture of the abdominal wall mass, and 5 mL of purulent fluid was pierced and sent for bacterial
culture, and cultured "Mycobacterium Senegalense", after 3 days of treatment with "cephalosporin" antibiotics (specifically
unknown), the symptoms did not improve, so she went to the second affiliated hospital of hainan medical college. After
completing the relevant examinations during the hospitalization in our hospital, in order to clarify the etiology, another
abdominal puncture to extract pus was performed, the mycobacterial culture + identification results: Mycobacterium
senegalense. Consistent with the out-of-hospital results, the diagnosis of Mycobacterium senegalense infection was confirmed.
After 3 months of treatment with "cefoxitin, azithromycin, amikacin, and levofloxacin", the patient's abdominal wall soft tissue
infection was cured. Trauma or invasive procedures can lead to skin, muscle, or bone infection with nontuberculous
mycobacteria (NTM), which can manifest as chronic painless nodules that progress to purulent folliculitis and abscesses. NTM
infection should be suspected when the patient's wound has been exposed to water, there is a history of surgery, and empirical
anti-infection is ineffective. This is the first case of Mycobacterium senegalense infection caused by medical beauty, which tell
people that they should be cautious when choosing medical aesthetic projects and medical aesthetic institutions.
