ObjectiveTo study an application of a method of improving the quality of sampling in review to determine the light areas of endemic fluorosis(referred to as endemic fluorosis) in quality control. Methods Of 15 light endemic fluorosis township(town), six were randomly sampled, and the prevalence of dental fluorosis in 22 village primary school children aged 8 to 12 were reviewed to determine the improved quality of sampling in Xuyong county Sichuan province. ResultsSix townships(towns) were selected by simple random sampling from 15 endemic fluorosis townships(towns) for review inspection in Xuyong country. A total of 22 villages were verified, accounting for 22.7％ of the total 97 villages verified. Of the 416 children for review inspection of dental fluorosis, 383 children were positive. The consistent rate of children' s dental fluorosis was 92.07％, and the verification to be slight villages was up to 21 endemic villages, accounting for 95.45％. ConclusionsThe application of a method of improving the quality of sampling can improve the efficiency of quality control, and improve the accuracy. It is a novel quality control method.

BACKGROUND: The gut is capable of inducing multiple organ dysfunction syndrome (MODS). In the diagnosis and treatment of critical ill patients, doctors should pay particular attention to the protection or recovery of intestinal barrier function. However, no reliable diagnostic criteria are available clinically. This study aimed to assess the changes of intestinal mucosal barrier function in surgically critical ill patients as well as their significance. METHODS: Thirty-eight surgically critical ill patients were enrolled as a study group (APACHE II>8 scores), and 15 non-critical ill patients without intestinal dysfunction were selected as a control group (APACHE II<6). General information, symptoms, physical signs, and APACHE II scores of the patients were recorded. The patients in the study group were subdivided into an intestinal dysfunction group (n=26) and a non-intestinal dysfunction group (n=12). Three ml venous blood was collected from the control group on admission and the same volume of plasma was collected from the study group both on admission and in the period of recovery. The plasma concentrations of endotoxin, diamine oxidase (DAO), D-lactate, and intestinal fatty-acid binding protein (iFABP) were detected respectively. The data collected were analyzed by the SPSS 17.0 software for Windows. RESULTS: The levels of variables were significantly higher in the study group than in the control group (P<0.01). They were higher in the intestinal dysfunction group than in the non-intestinal dysfunction group (DAO P<0.05, endotoxin, D-lactate, iFABP P<0.01). In the non-intestinal dysfunction group compared with the control group, the level of endotoxin was not significant (P>0.05), but the levels of DAO, D-lactate and iFABP were statistically significant (P<0.05). The levels of variables in acute stage were higher than those in recovery stage (P<0.01).The death group showed higher levels of variables than the survival group (endotoxin and D-lactate P<0.01, DAO and iFABP P<0.05). CONCLUSION: The plasma concentrations of endotoxin, DAO, D-lactate, and intestinal fatty-acid binding protein (iFABP) could reflect a better function of the intestinal mucosa barrier in surgically critical ill patients.

OBJECTIVETo detect the expression of protein 4.1 family members in mouse melanoma cell lines and evaluate their effect on cell proliferation.

METHODSPCR and Western blot were used to detected to the expression of protein 4.1 family members (4.1R, 4.1B, 4.1G, and 4.1N) at the mRNA and protein levels in B16 and B16-F10 cell lines. The expression plasmid vector pEGFP-N1-EPB41L3 carrying 4.1B gene sequence amplified from genomic RNA of mouse embryo fibroblasts was constructed and transiently transfected into mouse melanoma cells. The change in cell proliferation was assessed using MTT assay.

RESULTSThe mRNA and protein expressions of all the protein 4.1 family members, with the exception of 4.1B, were detected in both B16 and B16-F10 cells. Transfection of cells with the eukaryotic expression vector pEGFP-N1-EPB41L3 markedly inhibited cell proliferation as compared with the non-transfected cells.

CONCLUSIONThe eukaryotic expression vector carrying EPB41L3 sequence is capable of inhibiting the proliferation of mouse melanoma B16 and B16-F10 cells.

BACKGROUNDOff-label application of drug-eluting stents (DES) during percutaneous coronary intervention (PCI) was not uncommon in daily practice, however DES in treating Chinese patients with complex lesion subset was under-investigated. The primary objective of the FIREMAN registry was to evaluate the long term efficacy and safety of the Firebird sirolimus-eluting stent (SES) in treating patients with complex coronary lesions. Here we report the mid-term of one-year clinical outcomes and eight-month angiographic follow-up results of FIREMAN registry.

METHODSThe FIREMAN registry was a prospective multi-center registry, which included 1029 consecutive patients undergoing PCI with Firebird SES implantation between September 2006 and July 2007 in 45 centers in China. The clinical follow-up was designed to be performed at 1, 6, 12, 18, 24, 30 and 36 months post index procedure, and non-mandatory angiographic follow-up at 8 months was planned. One hundred percent site monitoring was conducted.

RESULTSLong lesions (59.2%), multi-vessel disease (50.4%), and small vessel disease (31.6%) were mostly found in angiography. Major adverse cardiac events (MACE) occurred in 51 (5.1%) patients at 1 year clinical follow-up, including cardiac mortality in 6 (0.6%), non-fatal myocardial infarction in 11 (1.1%), and target lesion revascularization in 36 (3.5%) of the patients. Definite and probable stent thrombosis (ST) by Academic Research Consortium (ARC) definition occurred in 12 (1.36%) patients at one-year clinical follow-up. The 8-month binary restenosis rate was 5.7% in-segment and 4.3% in-stent, respectively. Late lumen loss was (0.21 ± 0.40) mm in-segment and (0.23 ± 0.36) mm in-stent, respectively. Furthermore, Cox regression analysis revealed that diabetes, small vessel diameter, and chronic total occlusion were independent predictors of ST.

CONCLUSIONSThe results showed that the Firebird SES was effective and safe in treating Chinese patients with complex coronary lesions and occurrence of ST rate at one-year clinical follow-up was acceptable, however further long-term follow-up was still necessary. (NCT00552656)

Objective:Our study was aimed to analyze the therapeutic effect of early sequential enteral nutrition on postoperative rehabilitation in patients with gastric cancer.Methods:Patients with gastric cancer receiving surgery at our hospital from 2016 to 2017 included and the clinical information was prospective collected and analyzed.Patients were randomly divided into two groups using random number table.Patients in group A were sequentially given amino acid type,short peptide type and then whole protein type,while those in group B received whole protein formulation only.The recovery of gastrointestinal function,postoperative systemic inflammatory response,six-minutes walking test,and enteral nutrition-related complications were compared between the two groups.Results:A total of 71 patients were included in this study (Group A 36 cases,Group B 35 cases).There was no significant difference in terms of the restart anal exhaust between the two groups (P ＞ 0.05).Patients in group A had a significantly shorter postoperative hospitalization (t =4.070;P ＜ 0.01) and the earlier restoration of oral intake than that of Group B (t =3.400;P =0.001).One week after surgery,the levels of CRP (t =2.547;P =0.013) and IL-6 (t =3.172;P =0.002) were significant lower in group A when compared with group B.In addition,patients in group A had a significant higher six minutes walk steps than those in Group B [(416.1 + 36.7) m vs (358.9 ± 32.7) m;t =6.927,P ＜ 0.01].However,no significant difference in enteral nutrition-related complications was found between the two groups (P ＞ 0.05).Conclusion:In patients with gastric cancer,early sequential enteral nutrition can effectively accelerate the postoperative rehabilitation.

OBJECTIVE: To investigate the incidence of neonatal asphyxia and possible contributing factors for the development of severe asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture, China. METHODS: A total of 16 hospitals in Hubei Enshi Tujia and Miao Autonomous Prefecture were selected as research centers. A retrospective analysis was performed for the clinical data of 22 294 live births in these 16 hospitals from January to December, 2016 to investigate the incidence rate of neonatal asphyxia and possible contributing factors for the development of severe asphyxia. RESULTS: Of the 22 294 neonates born alive, 733 (3.29%) were diagnosed with neonatal asphyxia, among whom 627 had mild asphyxia and 106 had severe asphyxia. The neonates with low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight had a higher incidence of severe asphyxia (P<0.05). CONCLUSIONS The incidence rate of neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture is higher. Low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight may be related to the development of severe neonatal asphyxia.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.
