The preventive effects of starch-Fe and sucrose-Fe on iron deficiency anemia were investigated. Weaning rats were used as experimental animal, and divided into starch-Fe, sucrose-Fe, ferrous sulfate and control group. The former 3 groups were set for the Fe deficiency preventive group and each animal received elemental iron 5-6mg per kg body weight per day according to its preparation demand orally. The control group was given ordinary diet only. After 24-day feeding with its experimental diet serum iron(SI), serum ferritin (SF) and hemoglobin (Hb) of the animal were measured. The results revealed that SI (?g/dl) was 111.08 ? 22.30,118.64?26.80, 136.81?54.36 and 83.44?22.60; SF (ng/ml) was 12.69?3.19, 14.52?1.98, 16.91?2.02 and 7.51?2.09; Hb (g/dl) was 10.71?0.63, 10.96 ?0.45, 11.01?0.84 and 8.46 ? 1.27 respectively. This suggested that the starch-Fe and sucrose-Fe could be well absorbed and probably favorable to rescue children from iron deficiency anemia.

OBJECTIVE:To investigate the distribution of common bacterial pathogens and their drug resistance in our hospi-tal,and to provide guidance for clinical treatment and promote rational drug use. METHODS:The results of microorganism cul-ture,isolation and identification,and drug sensitivity test were collected from our hospital during Aug. 2010-Sept. 2014. The isolat-ed pathogens and drug sensitivity were analyzed statistically. RESULTS:14 687 strains of bacterial pathogens were isolated or cul-tured in 4 years,among which 1 790 strains of Pseudomonas aeruginosas were most common Gram-negative bacterium,followed by 1 313 strains of Escherichia coli and 770 strains of Klebsiella pneumoniae,670 strains of Bauman acinetobacter;915 strains of Staphylococcus aureus were most common Gram-positive bacterium,followed by 223 strains of Enterococcus faecalis,98 strains of Staphylococcus haemolyticus;1 446 strains of Mycoplasma urealytium were the most common microorganism,followed by 769 strains of Candida albicans,187 strain of Mycoplasma hominis. CONCLUSIONS:Regular detection of bacteria distribution and bacterial resistance monitoring are conducive to understand the bacterial resistance of the medical institutions so as to provide guid-ance for clinical treatment and promote reasonable application of antibacterial drugs.

OBJECTIVE:To evaluate therapeutic efficacy and ADR of amphotericin B in the treatment of AIDS combined with fungal infections retrospectively. METHODS:The cases of amphotericin B in the treatment of AIDS combined with fungal in-fections were collected our hospital. Total therapeutic efficacy,distribution of pathogenic bacteria,clearance rate and ADR were evaluated. RESULTS:89 patients were involved totally,among which 45 cases were marked effect,32 cases improved and 12 cas-es failed,with effective rate of 86.5%. The fungus were found or cultured in 76 cases,among which 64 strains were cleared,but 12 strains were not,with total clearance rate of 84.2%. There were 41 ADR cases(46.1%),while all completed the treatment ex-cept 2 developing severe renal failure(2.2%). CONCLUSIONS:Domestic amphotericin B could effectively treat AIDS complicat-ing with fungal infections,and the ADRs were acceptable.

Objective:To investigate the risk factors and clinical significance of lymph nodes metastasis between sternocleidomastoid and sternohyoid muscle lymph node (LNSS) metastasis in thyroid cancer patients, so as to guide the reasonable dissection of LNSS region and lateral cervical lymph node in patients with papillary thyroid carcinoma (PTC) .Methods:We selected 111 PTC patients with lateral cervical lymph node metastasis who underwent radical thyroidectomy and lateral cervical lymph node dissection from Nov. 2018 to Dec. 2021 in China-Japan Union Hospital of jilin university. All patients were treated with low collar arc incision. Radical thyroidectomy and lateral cervical lymph node dissection were performed according to the guidelines, and lymph nodes in each district were grouped for pathological examination. According to whether LNSS metastasis occurred, they were divided into two groups: LNSS positive group (LNSS metastasis occurred) and LNSS negative group (LNSS metastasis did not happen). We collected the basic information of all 111 PTC patients with lateral lymph node metastasis (LLNM), preoperative color Doppler ultrasound examination and paraffin-embedded pathology and other related clinical case data. Then we described the clinicopathological features of cervical lymph node metastasis. Independent sample t test and Mann-Whitney U test were used for continuous variables, and Fisher exact test was used for data analysis for classified variables. Correlation analysis adopted binary logistics regression model, and analyzed the regularity and risk factors of LNSS metastasis. Results:In this study, the detection rate of LNSS was 64.9% (72/111), the overall LNSS metastasis rate was 7.2% (8/111), and the number of lymph node metastasis was 0-5. Univariate analysis showed that the location of LNSS metastasis was related with the cancer focus ( P<0.001), the preoperative serum thyroglobulin (Tg) level ( P=0.002), the number of lymph node metastasis in lateral cervical level Ⅳ ( P=0.001), the longest diameter of the cancer focus ( P=0.003) and the longest diameter of metastatic lymph nodes ( P=0.001) However, age, sex, whether there is lymph node metastasis in the central region (central lymph node metastasis ,CLNM), and whether there is multifocal cancer were not related to LNSS metastasis ( P≥0.05). Further multivariate analysis and work curve analysis of subjects showed that the tumor located in the lower pole ( P=0.014) and the number of lymph node metastasis in level Ⅳ more than 3 ( P=0.027) were independent risk factors for LNSS metastasis. It was found that the risk of LNSS metastasis increased when the cancer focus was located at the lower pole relative to the upper pole or middle part of the cancer focus ( OR=74.508, 95% CI: 2.373-2339.544). The number of lymph node metastasis in level Ⅳ had a positive effect on LNSS metastasis. The more lymph node metastasis in level Ⅳ, the higher the risk of LNSS metastasis ( OR=1.556; 95% CI=1.051-2.303) . Conclusions:In PTC patients with LLNM, the LNSS metastasis rate was 7.2%, and the advantages of LNSS cleaning outweigh the disadvantages. When the cancer focus is located at the lower pole and the number of lymph node metastasis in region Ⅳ is more than 3, it is necessary to pay attention to the dissection of this group of lymph nodes.
