Methods TFBF in different dosages (0.1 g?kg -1?d -1,0.2 g?kg -1?d -1,0.4 g?kg -1?d -1) was taken orally by streptozotocin-induced diabetic rats for 12 wk. After the treatment, blood glucose, fructosamine and AGEs in plasma and kidney were measured. Meanwhile, glucose and bovine serum albumin (BSA) were incubated with TFBF at different concentrations (0.01 mg?L -1,0.05 mg?L -1,0.10 mg?L -1) respectively for 4,8,12 wk.The fluorescence intensity of glycated BSA was detected by a spectrophotometer BSA was detected spectrophotometer.Results TFBF significantly lowered the level of blood glucose in diabetic rats (P

Objective To master the condition of iodine deficiency disorders (IDD),residents iodine nutritional status and implementation of prevention measures in Gansu Province and to provide a basis for developing control strategies.Methods Thirty primary schools were selected in Gansu Province utilizing cluster sampling methodology in 2011,In each selected school,40 children aged 8-10 were randomly selected for thyroid examination and urine samples were collected from 12 children,at the same time measuring the average daily salt intake of domestic residents by 3 days weighing method.On the spot random urine samples and salt samples were collected from a subset of children included in the study.Three towns near the selected school were selected randomly and random urine samples were collected from 5 pregnant and 5 lactating women in each selected town.One drinking water sample was collected for analysis from different sources in five directions(east,south,west,north and central)in each administrative village with the sampled schools.In areas with centralized water supply,two tap water samples were collected for analysis.Results The water iodine median of 83 water samples was 2.02 μg/L,the range was 0.20-36.92 μg/L,and iodine median of 1199 salt samples was 27.4 mg/kg,iodine level in 89.2％ (74/83) of the water samples was lower than 10 μg/L.The iodized salt coverage rate was 98.0％ (1175/1199),the qualified rate of iodized salt was 90.3％ (1061/1175) and the consumption rate of qualified iodized salt was 88.5％ (1061/1199).Total of 360 salt samples intake of households were collected,per capita daily salt was 8.5 g,and the range was 2.5-17.8 g.Total of 1200 children thyroid were checked,the thyroid goiter rate(TGR)of children was 2.8％(34/1200) by B-ultrasound and 3.5％ (42/1200) by palpation.Total of 359,450 and 450 urine samples of childen aged 8-10,pregnant and lactating women,the urinary iodine median were 216.0,168.6,161.9 μg/L,respectively.Conclusions Great progress has been made in the prevention and control of IDD in Gansu Province.IDD has been controlled effectively and the urinary iodine medians are at optimal levels.

BACKGROUND: This study was undertaken to determine the effect of mesenchymal stem cells (MSCs) engraftment on vascular endothelial cell growth factor (VEGF) in lung tissue, plasma and extravascular lung water at early stage of smoke inhalation injury. METHODS: A rabbit smoke inhalation injury model was established using a home-made smoke inhalation injury generator, and rabbits were divided into two groups randomly: a control group (S group, n=32) and a MSCs treatment group (M group,n=32). 10 ml PBS was injected via the ear marginal vein immediately at injury into the S group. Third generation MSCs with a concentration of 1×107/10 ml PBS were injected via the ear marginal vein immediately at injury into the M group. VEGF in peripheral blood and lung tissue were measured at 0 (baseline), 2, 4 and 6 hours after injection respectively and analyzed. The right lungs of rabbits were taken to measure lung water mass fraction. RESULTS: In the lung tissue, VEGF decreased gradually in the S group (P<0.05) and signifi cantly decreased in the M group (P<0.05), but it increased more signifi cantly than the values at the corresponding time points (P<0.05). In peripheral blood, VEGF increased gradually in the S group (P<0.05) and markedly increased in the M group (P<0.05), but it decreased more signifi cantly than the values at corresponding time points (P<0.05). CONCLUSION: MSCs engraftment to smoke inhalation injury could increase VEGF in lung tissue, decrease VEGF in plasma and reduce extravascular lung water, indicating its protective effect on smoke inhalation injury.

Objective To preliminarily evaluate the value of color power doppler ultrasonography in the diagnosis of sacroiliitis in ankylosing spondylitis(AS). Methods Fifty-seven sacroiliac joints in 31 patients with active AS and 40 sacroiliac joints in 20 volunteers were detected by color power doppler ultrasonography.The color flow signs inside the sacroiliac joints were observed,and the resistance index(RI) was measured. Results In active AS,color flow signs were seen in 55 joints,and the mean RI value was 0.53?0.08 in 45 joints,while the other 10 color flow signs represented reversed phase in diastolic phase on pulse doppler ultrasonography.In the volunteers,color flow signs were seen in 16 joints,and the mean RI value was 0.97?0.01 in 6 joints,while the other 10 color flow signs represented reversed phase in diastolic phase on pulse doppler ultrasonography. Conclusion The abnormal flow signs at the sacroiliac joints can be detected by color power doppler ultrasonography.Low RI values provide diagnosis evidence for active AS.

The present study was undertaken to investigate the linkage between angiotensin-(1-7) ［Ang-(1-7)］ and the release of amino acid neurotransmitters in the the rostral ventrolateral medulla (RVLM) by techniques of microinjection, microdialysis combined with high performance liquid chromatography (HPLC)-fluorescent detection. Unilateral microinjection of Ang-(1-7) into the RVLM of anesthetized rats produced an increase in mean arterial pressure (MAP) accompanied by an increased release of glutamate (Glu). In contrast, microinjection of Ang779, a selective antagonist of Ang-(1-7) receptor, caused a decrease in MAP with a decreased releaceof Glu and an increased release of glycine,taurine and r-aminobutyric acid.The pressor effect of Ang-(1-7)and the depressor effect of Ang779 were in part blocked by corresponding andtagonists of aminoacid receptors.These results suggest that the pressor effect of Ang-(1-7)in the RVLM may be partially due to an increased release of Glu,whereas the depressor effect of Ang779 may be partially attributed to a decreased release of Glu and an increased release of inhibitory amino acid neurotransmitters

Objective To clarify the clinical features,therapeutic strategy and prognosis of lipid storage myopathy (LSM).Methods The clinical data and therapeutic effects of 42 LSM patients were summarized retrospectively.All patients were followed up to evaluate their prognosis.Results Data of short-term therapeutic results of all the 42 patients were available.Thirty-three cases were placed in low- doses prednisone and 9 cases in riboflavin.All patients showed marked and quick improvement of symptoms within one month.Among thirty-two patients followed up for more than one year,26 cases had a full recovery and 6 remained to have intolerance to heavy exercise.Thirteen patients had relapses of muscle weakness in various degrees and most of which were induced by exertion,exposure to coldness and upper respiratory tract infection.In 5 patients the symptoms were recurred for more than one time.Among 13 cases with relapses, 7 had family history.Conclusions Our data suggest that LSM is a treatable disease and well responsive to low-doses prednisone.The disease tends to recur,especially in patients with family history.Glutaric aciduria type Ⅱ should be considered in LSM patients who are responsive well to riboflavin,indicating drug therapeutic strategy for LSM should be based on the etiology of the disease.

Objective To investigate the control status of iodine deficiency disorders (IDD) in the highrisk areas of Gansu province,and to provide a scientific basis for development of effective preventive measures.Methods Twelve counties with high-risk areas of IDD in Gansu province were selected into the survey in 2007 -2009.All patients with suspected cretinism born after the first of January,1997 were enrolled in the study from the 12 counties.Meanwhile,three townships were chosen in each of the 12 counties,two villages were taken in each township,40 children aged 8 to 10 in each village primary school were selected to carry out thyroid examination by B-ultrasonography and palpation,urinary iodine(UI) test,and intelligence quotient(IQ) test; 30 women of childbearing age were selected in each village to fill in the questionnaire,and to test their urinary and salt iodine,and the local salt-related situation was investigated.Results In the 12 high-risk counties,7 were diagnosed as new cretinism cases from a total of 120 suspected cases of cretinism.The goiter rate of children aged 8 - 10 by Bultrasound was 6.8％(290/4281 ),5 counties had goiter rates higher than 5％,of which 3 counties had goiter rates higher than 10％.The average IQ of children was 82.38.The median urinary iodine(MUI) of children was 180.34 μg/L,the ratio of UI ＜ 50 μg/L was 11.0％(482/4383).The MUI of women of childbearing age was 175.91 μg/L,the ratio of UI ＜ 50 μg/L was 16.5％(126/762).MUI of women of childbearing age was less than 100.0 μg/L in Xiahe and Dongxiang counties,which were 95.24 μg/L and 66.30 μg/L,respectively.The coverage rate of iodized salt in 8 of the 12 counties was more than 95％,and that of the remaining four counties was ＜ 85％,of which the coverage rates of iodized salt were only 39.2％ (47/120)and 66.7％ (120/180),respectively,in Guanghe and Dongxiang counties.Fourteen point nine percent (206/1380) of the residents complained that iodized salt was not convenient to buy and 87.7％ (1210/1380) complained that the current price of these salts exceeded the accepted range.Only 29.9％(413/1380)of the housewives knew how to prevent IDD.Conclusions Impact factors of IDD in high-risk areas are widespread.The monitoring of IDD in high-risk areas should be strengthened.Effective measures should be taken to ensure adequate iodine nutrition of people at risk.At the same time,iodized salt-based comprehensive prevention measures should be strengthen and a long-term effective control strategy of IDD should be established.

15 scores were randomly divided into therapeutic group (30 cases)and control group(30 cases).The two groups were treated with the same conventional therapy. From the 1st day of admission,Xuebijing injection 80 ml was given by intravenous drip once for every 12 hours for 7 days to the therapeutic group.The level of tumor necrosis factor-?(TNF-?),interleukin-1?(IL-1?),IL-6,IL-10,and APACHEⅡscore were tested on 1,3,5 and 7 days after admission.The case fatality and incidences rates of sepsis and MODS in both groups were recorded.Results Compared with the control group,APACHEⅡscore,TNF-?,IL-1?,IL-6 and IL-10 of the therapeutic group were lower significantly on the 3rd day after admission,especially on the 5th day(all P

Objective To understand the genotyping of human immunodeficiency virus (HIV) co-infected hepatitis C virus (HCV) patients in Yunnan Province, and to analyze the differences in viral load, biochemical indicators, and blood routine indicators among different genotypes, in order to provide a laboratory basis for the diagnosis and clinical treatment of HIV/HCV co-infected patients. Methods From November 2022 to June 2023, the serum samples and basic information of patients diagnosed with HIV/HCV co-infection were collected in the antiviral outpatient clinic of Yunnan Provincial Hospital of Infectious Diseases. The HCV viral load was detected by one-step qRT-PCR amplification, the positive samples were sequenced, and genotyping was determined based on NS5 gene sequence. The differences in biochemical and blood routine indexes between HIV patients co-infected with different HCV genotypes and low/high viral loads were analyzed. Results A total of 126 HIV/HCV co-infected patients were collected, including 20 HCV genotype 1 (15.9%), 91 HCV genotype 3 (72.2%), and 15 HCV genotype 6 (11.9%). The maximum and minimum viral load of the three HCV genotypes were as follows: HCV type 1 (1.0×108, 4.8×104 IU/mL), HCV type 3 (2.2×108, 2.9×102 IU/mL), and HCV type 6 (8.1×107, 6.8×104 IU/mL). The results showed that there was no significant difference between HIV co-infection with different genotypes of HCV and three HIV treatment schemes, including nucleoside reverse transcriptase inhibitors+integrase strand transfer inhibitors (NRTIs+INSTIs), nucleoside reverse transcriptase inhibitors+non-nucleoside reverse transcriptase inhibitors (NRTIs+NNRTIs) and nucleoside reverse transcriptase inhibitors+protease inhibitor (NRTIs+PLs), and the viral load of patients (P>0.05). The analysis of biochemical indexes such as total bilirubin (TBIL), direct bilirubin (DBIL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (CREA), and blood routine indexes such as white blood cell (WBC), red blood cell (RBC), hemoglobin (HGB), platelet (PLT), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) among different HCV genotypes and low/high viral loads showed that there was no significant difference in biochemical indexes and blood routine indexes between low/high viral loads of HIV co-infected HCV patients (P>0.05); however, the biochemical indicators TBIL, IBIL and MCHC were significantly different statistically between patients with genotype 3 HCV infection and those with genotype 1 HCV infection (P<0.05), while other biochemical and blood routine indexes were not statistically different among different HCV genotypes (P>0.05). Conclusions There are six subtypes of HCV co-infection in HIV patients in Kunming, Yunnan Province, including three genes of genotype 1, 3, and 6. Among them, genotype 3 HCV is the main prevalent genetic virus among HIV co-infected populations. The TBIL, IBIL and MCHC values of HIV patients co-infected with HCV type 3 are different from those infected with HCV type 1.
