Objective To investigate the frequency of therapy-oriented oral radiation in Nanping, China and its distribution, and to provide a basis for the rational application of therapy-oriented oral radiation and the effective allocation of resources in Nanping. Methods A questionnaire was designed to investigate the frequency of therapy-oriented oral radiation in all oral radiation diagnosis and treatment institutions in Nanping. Results In 2021, there were 54 oral radiation diagnosis and treatment institutions and 79 oral radiation machines in Nanping. The total frequency of therapy-oriented oral radiation was 61593 visits and the radiation frequency was 19.54 visits per thousand patients. The average annual frequency of medical institutions at all levels was 721.87 to 3713.25 visits per institution; the male-to-female composition ratio of frequency of therapy-oriented oral radiation in December 2021 was 50.5%:49.5%. The proportion of radiation frequency of different devices was as follows: 38.7% (intraoral dental film), 46.5% (oral panorama), 10.3% (oral computed tomography [CT]), and 4.5% (cranial photography). The proportion of radiation frequency in patients of different ages was as follows: 17.1% (0−15 years), 48.2% (15−40 years), and 34.7% (over 40 years). The frequency of therapy-oriented oral radiation grew by 77.43%, 35.18%, and 8.16% every two years from 2015 to 2021, respectively. Conclusion The frequency level of therapy-oriented oral radiation in Nanping is at the level of Class II health care. The distribution of therapy-oriented oral radiation is highly unbalanced and is related to the level of economic development. Private healthcare institutions are growing rapidly, and public healthcare institutions of grade two and above occupy the main healthcare resources. The oral panorama accounts for the most, cranial photography accounts for the least, and oral CT is the fastest-growing portion. Therapy-oriented oral radiation is predominantly performed in the young and middle-aged populations, regardless of sex. Except for intraoral dental films, the general trend is upward.

Objective To investigate the value of Pituitrin in neonatal cardiopulmonary resuscitation.Methods Seventy-three cases with neonatal cardiopulmonary arrest admitted in emergency department and NICU in our hospital were collected during 2007 to 2011.Newborns who did not respond to conventional neonatal resuscitation therapy were divided into two groups:epinephrine group 47 cases (control group) and Pituitrin combined with epinephrine group 26 cases (treatment group).Results There were no statistical difference (x2 =0.956,P ＞ 0.05) between treatment group and control group in the rates of initial resuscitation success (23.1％,6/26 vs 34.0％,16/47).Conclusion Pituitrin combined with epinephrine has similar efficacy with the use of epinephrine in neonatal cardiopulmonary resuscitation.

Objective To study the role of recombinant human epidermal growth factor (rhEGF) in the prognosis of multiple organ dysfunction syndrome (MODS) in mice. Methods One hundred and twenty clean male Kunming mice were randomly ( random number) divided into normal saline control group (n =15),MODS model control group (n =15) and MODS + rhEGF treatment group (n =90).The MODS models were made by using Caballero ME method with thioacetamide (TAA) 2000 mg/kg injected intraperitoneally to establish monophasic rapid onset pattern of MODS model in mice.MODS + rhEGF treatment group was further randomly divided into two subgroups,namely intraperitoneal injection group (n =45 ) and subcutaneous injection group (n =45 ).Each subgroup was divided again into three small subgroups (n =15) as per different doses of rhEGF used,namely 10 μg/kg,30 μg/kg and 50 μg/kg.Within 24 hours after modeling,the respiration,body weight,food eaten and general physical changes were observed.Mortality was calculated 24 hours after modeling.After the animals sacrificed,the tissues of viscus including liver,kidney,heart,brain,lung,spleen,pancreas,intestine and stomach were collected immediately.The histological changes of visceral tissues were studied by using hematoxylin -eosin staining under the light microscope.All the experimental data were presented in,and body weight changes were compared using t-test,and after different routes of administration with different doses of rhEGF used in MODS,the mice body weight changes were analysed by using the Dunnett method,and the mortalities of mice were compared by using Fisher exact test,and P ＜ 0.05 was considered statistically significant difference. Results There was no significant difference in mortality betweeu mice in rhEGF subcutaneous administration group and MODS model control group (P ＞ 0.05 ),but the total mortality of hrEGF MODS intraperitoneal administration group (6.7％ in dose of 50 μg/kg and 20％ in dose of 30 μg/kg) was significantly lower than that of MODS model control group (73.3％) ( P ＜ 0.05 ) and the mortality of mice treated with intraperitoneal 50μg/kg rhEGF (6.7％ ) was lower than that treated with 10μg/kg rhEGF (P=0.014).The mortality of mice in rhEGF MODS (50 μg/kg ) intraperitoneal administration group was significantly lower than that in subcutaneous administration group (40％) (P =0.031 ), The histopathological changes in rhEGF MODS treatment group were not as remarkable as seen in mice of control group.The histopathological changes were dose - dependent.The higher doses of rhEGF,the lesser hepatic congestion,liver cell apoptosis,hepatic cell cloudy swelling and cell vacuolization.Similarly,as RhEGF dosage increased,pulmonary interstitial congestion,inflammatory cells and apoptotic bodies reduced,and bronchial ciliated columnar epithelium less shed.Conclusions RhEGF plays a positive role in repairement of tissue damage in TAA - induced MODS murine model.The rhEGF given by intraperitoneal route of administration is more effective to reduce the 24 h mortality of MODS mice than that by subcutaneous route.

DC-specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN) is specific receptor on Dendritic cells, and plays a pivotal role on antigens presentation. Uptodate, the clear regulation mechanisms for DC-SIGN expression are not available.IL-4 is one of the most important cytokines inducing DC-SIGN production, while, NF-κB is an important transcription factor controlling signaling transduction. Both IL-4 and NF-κB are closely related to DC-SIGN regulation. NF-κB and IL-4 actions on DC-SIGN promoter activity, DC-SIGN expression as well as interactions between IL-4 and NF-κB were investigated in THP-1 cell. It was found that the mutation of NF-κB binding site in DC-SIGN promoter results in DC-SIGN promoter activity decrease about 50%.NF-κBp50 stimulates DC-SIGN expression in THP-1 cells. IL-4 upregulates DC-SIGN expression on THP-1 cells as well as NF-κB production. These data reveal that NF-κB is associated with IL-4 induced DC-SIGN expression.

Objective To explore the relationship between the genetic polymorphism and serum concentration of mannan binding lectin (MBL)and the clinical manifestation of the hand-foot-mouth disease (HFMD) children infection by human enterovirus 71 (HEV71).Methods One hundred and thirty-eight children diagnosed as HFMD infected by HEV71 (including 80 mild cases and 58 severe cases) and 40 healthy,symptom-free children were investigated.The concentrations of serum MBL were measured in 40 healthy controls,80 mild HFMD cases and 56 severe HFMD cases at both acute and convalescent phases by a sandwich enzyme immunoassay with a human MBL ELISA kit.And the genomic DNA of all cases were extracted from blood according to standard phenol-chloroform procedure.Six SNPs in the MBL gene(-550G/C,-221G/C and +4C/T of the promoter,CGT52TGT,GGC54GAC,and GGA57GAA of the exon 1) were analyzed by a sequencing-based typing method.Results The MBL serum level of the severe HFMD circulatory respiratory failure group in acute phase was significantly increased compared with severe HFMD encephalitis group,the mild cases and the control,but in the convalescence phase it significantly decreased compared with them.The frequencis of type B/B mutation (+230 of the exon 1),type P/P mutation (+4C/T of the promoter),and type H/H mutation (-550G/C of the promoter) were a significant difference among mild group,severe group and the control(P=0.006,0.043,0.028,respectively).The frequencies of LYPB/LYPB genotype and HYPA/HYPA genotype were a significant difference among mild group,severe groupand the control (P=0.028,0.014,respectively).Conclusion Low MBL protein level as a result genetic polymorphism seems to be correlative with clinical manifestation of HFMD disease.The MBL gene mutation and low MBI.protein level may be used as one of the evaluation method of HFMD severeity.

OBJECTIVETo investigate the effects of atorvastatin on advanced glycation end products (AGE) induced monocyte chemoattractant protein-1 (MCP-1) expression in human umbilical vein endothelial cells (HUVECs) and whether this effect could be linked to peroxisome proliferator-activated receptor-γ (PPAR-γ) and nuclear factor-κB (NF-κB).

METHODSGrouping: (1) Blank control group; (2) BSA group; (3) AGE group: cells were incubated with different concentrations of AGE (10(-4), 10(-3), 10(-2) and 10(-1) g/L) for 24 hours; (4) AGE + Atorvastatin group: cells were incubated with different concentrations of atorvastatin (0.1, 1, 10 µmol/L) for 1 hour, then incubated with AGE (10(-1) g/L) for 24 hours; (5) PPAR-γ agonist (15 d-PGJ2) group: cells were incubated with 15 d-PGJ2 (10 µmol/L) for 1 hour, then incubated with AGE (10(-1) g/L) for 24 hours; (6) PPAR-γ inhibitor (GW9662) group: cells were incubated with GW9662 (5000 nmol/L) for 1 hour, then incubated with atorvastatin (1 µmol/L) and AGE (10(-1) g/L) for 24 hours. Collagenase was used to isolate the endothelial cell from human umbilical vein; RT-PCR was performed to examine the mRNA expression of MCP-1 and PPAR-γ; Western blot was performed to detect NF-κB p65 protein.

RESULTS(1) The expression of MCP-1 mRNA was increased in proportion with increasing concentrations of AGEs which could be blocked by atorvastatin in a dose-dependent manner. (2) AGE (10(-1) g/L) significantly downregulated the expression of PPAR-γ mRNA (0.22 ± 0.08 vs. 0.69 ± 0.09, P < 0.01) while upregulated the expression of phospho-NF-κB p65 protein (0.78 ± 0.06 vs. 0.31 ± 0.01, P < 0.01) and nonphospho-NF-κB p65 protein (1.61 ± 0.16 vs. 0.59 ± 0.14, P < 0.01) compared with the control group which could be significantly attenuated by atorvastatin. (3) PPAR-γ agonist decreased the expression of phospho-NF-κB p65 protein (0.21 ± 0.01 vs. 0.78 ± 0.06, P < 0.01), nonphospho-NF-κB p65 protein (0.67 ± 0.14 vs. 1.61 ± 0.16, P < 0.01) and MCP-1 mRNA (0.17 ± 0.02 vs. 0.93 ± 0.12, P < 0.01) compared with AGE (10(-1) g/L) group. (4) PPAR-γ inhibitor antagonized the effect of atorvastatin on the expression of phospho-NF-κB p65 protein, nonphospho-NF-κB p65 protein and MCP-1 mRNA stimulated by AGE in HUVECs (P < 0.01).

CONCLUSIONThe anti-inflammatory properties of atorvastatin in AGE stimulated HUVECs may partly be attributed to the effect on upregulation of PPAR-γ and downregulation of NF-κB signaling pathway.

OBJECTIVETo observe the intervening effects of Xuezhikang Capsule (XZK) on levels of blood lipid and other related indices in patients with different Chinese medical syndrome patterns of non-alcoholic fatty liver disease complicated carotid atherosclerosis (NAFLD-CAS), and to seek out the most appropriate pattern to indicate XZK for making guidance of its utilization.

METHODSChinese medical syndrome in 74 patients of NAFLD-CAS were classified into 4 patterns, 34 of Pi-deficiency phlegm-dampness pattern (A), 24 of dampness-heat accumulation pattern (B), 12 of phlegm-stasis intertwined pattern (C), and 4 of Gan-Shen yin-deficiency pattern (D). Excepting those of pattern D were excluded due to too small samples, all patients were treated with XZK for 3 months. Blood levels of blood lipids, including triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C), as well as high-sensitivity C-reactive protein (hs-CRP), and tumor necrosis factor alpha (TNF-alpha) were detected and compared before and after treatment.

RESULTSThe effective rate of XZK on patients of the three patterns, in A-C order, was 97.06%, 91.67%, 91.67%, respectively, with the optimal overall efficacy showed on pattern A. All the indices detected significantly decreased after treatment in all three patterns (P < 0.01), among them, excepting the difference of TG level between groups showed no significance (P > 0.05), the decrements of others were more significant in pattern A than in other two patterns (P < 0.05 or P < 0.01).

CONCLUSIONXZK could reduce the levels of blood lipids, hs-CRP and TNF-alpha in NAFLD-CAS patients, and the Pi-deficiency phlegm-dampness syndrome pattern was the optimal indication of XZK treatment.
