Objective: To observe the clinical efficacy of Nie-pinching the spine, puncturing Sifeng (EX-UE 10) plus Chinese herbs in treating pediatric anorexia due to dysfunction of spleen in transportation. Methods: A total of 64 kids were randomized into an observation group and a control group by the random number table method, with 32 cases in each group. Patients in both groups received Jian Pi Kai Wei (strengthening spleen and stomach) powder according to pattern differentiation of traditional Chinese medicine (TCM). In addition, patients in the observation group received Nie-pinching the spine and puncturing Sifeng (EX-UE 10). Nie-pinching the spine was applied twice a week, and puncturing Sifeng (EX-UE 10) was performed once a week, with 2 weeks counted as 1 course of treatment. After 2 courses of treatment, the body mass index (BMI), peripheral blood leptin level and the microelements Zn, Fe and Se were compared at different time points (before treatment, after the first and second courses of treatment), as well as the therapeutic efficacy and onset time. Results: After 2 courses of treatment, 31 cases in each group were evaluated. After the 1st course and the 2nd course, the BMI and serum Zn, Fe and Se levels in the observation group increased significantly (all P<0.05), the leptin level decreased substantially (both P<0.05); the BMI in the control group showed a substantial rise (P<0.05), while the Zn, Fe and Se levels slightly increased showing no statistical significance (all P>0.05), and the leptin level decreased but the difference showed no statistical significance (P>0.05). After the 1st and the 2nd courses of treatment, the BMI, serum Zn, Fe and Se levels increased more significantly (all P<0.05), and the serum leptin level decreased more significantly (both P<0.05) in the observation group than in the control group. After the 2nd course, the total effective rate and recovery rate in the observation group were both higher than those in the control group (both P<0.05), together with a quicker onset time (P<0.05). Conclusion: Nie-pinching the spine, puncturing Sifeng (EX-UE 10) plus Chinese herbs is effective for pediatric anorexia due to dysfunction of spleen in transportation. It can decrease leptin, increase Zn, Fe and Se levels, alleviate apositic symptoms and increase BMI in the kids.

The temperature and salinity ranges for growth of twelve strains of marine Bdellovibrio-and-like organisms (BALOs) which affiliated with four different phylogenetic clusters in the family Bacteriovoracaceae and the lytic ability of them to six kinds of common shrimp pathogen vibrios were studied. The morphological characteristics of four representative strains were examined with transmission electron microscope. The results showed that the strains within the same cluster or sub-cluster had identical growth temperature or salinity. The growth temperature ranges of clusters IV, VI, IX and X strains were 20?C～35?C, 15?C～35?C, 15?C～40?C, 10?C～40?C, respectively, and the optimum growth temperature was about 30?C or 35?C. The growth salinity ranges of clusters IV, VI, IX and X strains were 5‰～40‰, 2.5‰～30‰, 5‰～60‰ and 5‰～60‰, and the optimum salinities were about 10‰, 5‰, 20‰ and 20‰, respectively. Three of the six kinds of vibrios tested were lysed by all the BALOs, while the others could only be lysed by some of the BALOs. However, differential lysis to some of the vibrios was also observed among BALOs within the same cluster. The four strains of different clusters all exhibited typical BALOs morphology, hav-ing vibrioid cell with a single polar flagellum.

BACKGROUND: The mitochondrial apoptotic pathway is an important pathway in cell apoptosis. Previous studies have found that Bushen Zhuangdu Fang can improve intervertebral disc degeneration by inhibiting the mitochondrial apoptotic pathway in animal experiments. However, its mechanism of action is to be clarified. OBJECTIVE: To observe the effect of serum containing Bushen Zhuangdu Fang on mitochondrial apoptotic pathway key proteins of human nucleus pulposus cells, and to explore the mechanism by which this drug-containing serum improves intervertebral disc degeneration. METHODS: Thirty-seven male Sprague-Dawley rats were randomly divided into blank group, low-dose Chinese medicine group (0.506 g/kg per day), medium-dose Chinese medicine group (1.012 g/kg per day) and high-dose Chinese medicine group (2.024 g/kg per day). After 2 weeks of continuous administration, drug-containing serum was prepared. Human nucleus pulposus cells were randomly divided into normal group, cell model group, low-dose drug-containing serum group, medium-dose drug-containing serum group, and high-dose drug-containing serum group. The cell model group was treated with 200 μmol/L H2O2 for 6 hours, and the normal group received no treatment. The three drug-containing serum groups were treated with corresponding treatments for 48 hours. The pathological changes of nucleus pulposus cells were observed by transmission electron microscopy. Apoptotic rate of nucleus pulposus cells was detected by flow cytometry and mitochondrial membrane potential was detected by flow cytometry. Apaf1, Bcl-2, Bax and Cytc expressions were detected by real-time quantitative PCR and western blot assay. RESULTS AND CONCLUSION: Compared with the normal group, the apoptotic rate of nucleus pulposus cells with obvious apoptotic morphology was significantly increased (P < 0.05), the expression of Apaf1, Cytc, and Bax were significantly increased at mRNA and protein levels (P < 0.05), and the mitochondrial membrane potential and expression of Bcl-2 mRNA and protein were significantly decreased in the cell model group (P < 0.05). After treatment with drug-containing serum, the apoptotic rate of nucleus pulposus cells decreased significantly (P < 0.05), the expression of Apaf1, Cytc, Bax and their proteins decreased significantly (P < 0.05), and the mitochondrial membrane potential, Bcl-2 and their proteins increased significantly (P < 0.05). Therefore, the serum containing Bushen Zhuangdu Fang can effectively inhibit apoptosis of nucleus pulposus cells in a dose-dependent manner. The drug-containing serum may alleviate intervertebral disc degeneration by reducing the expression of Apaf1, Cytc and Bax and increasing the expression of Bcl-2 at protein and gene levels, and inhibiting the mitochondrial apoptotic pathway.

On the basis of the Uncaria transcriptome, specific primers were designed for UrSTR. The full-length cDNA of UrSTR (GeneBank: OL310251) was 1 541 bp, encoding 345 amino acid residues, and the promoter region sequence of UrSTR (GeneBank: OL310252) was 1 179 bp. Phylogenetic tree is revealed that UrSTR had a closest relationship with STR from Ophiorrhiza pumila and Ophiorrhiza japonica. Localization of UrSTR protein is revealed located in the vacuole membrane. Plant-care analysis indicated that the promoter region sequence of UrSTR, covering multiple light, stress and hormone-response cis-regulatory elements, and verified transcriptional activity. The results of SDS-PAGE show that pET-28a-UrSTR recombinant protein was successfully expressed, and the size was anticipated. The UrSTR prokaryotic expression system needs to be optimized in the later stage. The research lays the foundation for further purification to study its structure and functional characterization of the UrSTR protein.

Abstract: Objective　To investigate the distribution and drug resistance of pathogenic bacteria separated from ascites of patients in Children’s Hospital Affiliated to Zhengzhou University from 2015 to 2021, and to provide a basis for rational clinical antimicrobial agents. Methods　Bacterial culture, bacterial identification and drug sensitivity analysis were performed on 1 058 non-duplicate ascites culture specimens from January 2015 to December 2021. The clinica1 and microbiologica1 data were ana1yzed by WHONET 5.6 and SAS 9.4 Results　Of the 1 058 specimens, 586 (55.39%) were positive for pathogenic bacteria, with a total of 781 strains isolated. There was no significant trend of increase or decrease in the positivity rate over different years. Male children (63.99%) were more prevalent than female children. Appendicitis (59.22%) was the most common disease and Escherichia coli was the most common causative bacteria. Among neonates (≤28 d), the bacteria with the highest detection rate were Klebsiella pneumoniae (23.50%) and Enterococcus faecium (23.50%), while among children (>28 d), the highest detection rate was Escherichia coli (35.98%). Gram-negative bacteria accounted for 64.79% of the 781 strains, mainly Escherichia coli (38.28%), Klebsiella pneumoniae (8.58%), and Pseudomonas aeruginosa (5.89%); Gram-positive bacteria accounted for 29.45%, mainly Enterococcus faecium (8.58%), Streptococcus constellatus (2.69%), and Enterococcus avium (2.43%); fungi accounted for 1.66% and anaerobic bacteria accounted for 4.10%. The resistance rates of Escherichia coli to cefoperazone/sulbactam, piperacillin/tazobactam, imipenem and meropenem were 6.02%, 4.35%, 4.35%, and 3.68%, respectively. The resistance rates of Klebsiella pneumoniae to these drugs were 59.70%, 59.70%, 50.75% and 53.73% respectively. Linezolid-resistant strains of Enterococcus faecium were found. Conclusion　Appendicitis is the most common abdominal infection in children, and the distribution of ascites pathogens varies with ages and diseases. The pathogenic bacteria are mainly Gram-negative bacteria, and the drug resistance of Klebsiella pneumoniae was more serious. It is particularly important to use antibiotics correctly and rationally to reduce the emergence of drug resistant bacteria.

Objective To evaluate the nutritional status of iodine of pregnant and lactating women in coastal and inland areas of Zhejiang province,and to provide scientific basis for iodine supplementation.Methods In 2009,five coastal cities,five coastal counties and three inland areas from Zhejiang province were selected by the cluster sampling method,and one sub-district(township) was randomly selected in each city (county),then one community (village) was randomly selected in each sub-district (township).Thirty pregnant women,thirty lactating women and fifty children aged 8 - 10,were randomly selected in each community(village) as the investigation objects to collect instant urine samples to detect urine iodine,and to collect thirty resident edible salt and some water samples to detect salt iodine and water iodine,if the numbers of water source were more than 5 then 1 water sample was collected by their location of east,south,west,north and center in each community(village),otherwise,the numbers of water samples collected were equal to the number of community (village).Results The medians of salt iodine of coastal city,coastal county and inland area were 28.42,25.29,and 33.24 mg/kg,respectively,and the medians of water iodine correspondingly were 5.41,11.52,and 2.80 μg/L,respectively.The medians of urinary iodine of pregnant and lactating women in Zhejiang province were 148.72 and 161.34 μg/L,respectively,which were less than that of children aged 8 - 10(231.02 μg/L,Z =8.57,8.24,all P ＜ 0.017).The medians of urinary iodine in pregnant women from different areas were ranked in order as inland areas(211.42 μg/L),coastal counties (150.51 μg/L) and coastal cities (123.33 μg/L,Z =2.80,5.31,2.42,all P ＜ 0.017),and in lactating women,the medians of urinary iodine in inland areas( 197.43 μg/L) was higher than that in coastal cities( 139.64 μg/L,Z =4.03,P ＜ 0.017).Conclusions The overall levels of iodine nutrition in lactating and pregnant women in Zhejiang province are in the appropriate level,but that of the pregnant women in the coastal cities is inadequate.
