Objective To investigate the status of self-management behaviors and sense of coherence (SOC) in patients with type 2 diabetes as well as their correlation. Method A total of 348 patients with type 2 diabetes participated in the survey by way of the general demographic data form, diabetes self-care scale (2-DSCS) and sense of coherence scale (SOC-13). Results The total score on 2-DSCS was (65.61 ± 14.55), and 17.24%of them were scored fairly well. The total score on SOC-13 was (63.25 ± 11.46), with an average score of (4.87 ± 0.88) on every dimension of it. The total score on 2-DSCS together with its dimensions was positively correlated with the total score on SOC-13(P<0.05, P<0.01). Conclusions The SOC and self-management in patients with type 2 diabetes should be enhanced. In order to improve the level of self-management, nurses should take some individualized interventional measures based on the level of SOC in patients.

Objective To explore the inhibitory effects of Zibu Piyin Recipe(ZBPYR)serum on neuron apoptosis induced by tunieamyein(Tm,5 μg/ml)and its mechamsm in vitro by using sero-pharmacological method.Method Totally 12 healthy adult male SD rats(220～250 g)(SPF)were divided randomly into control group and ZBPYR group,6 in each group,then the blank and ZBPYR serum were prepared.The mouse.neuroblastoma cell line Neum2a cells were treated with Tunicamycin(Tin,an inhibitor of N-glycoslytion)to establish the endoplasmic reticulum(ER)stress model.The cells treated by ZBPYR aerum of different concentrations were interventional groups,and the cells treated by blank serum were control group.The viability of Neuro2a cells was meusurcdd by MTT assay.Flow cytometry wus applied to observe the apoptosis of Neuro2a cells.Western blotting was utilized to detect the protein expressions of two molecules,ER molecular chaperone-ucose regulated protein 78(CRP78)and transcriptional factor CCAAT/enhancer-binding protein-homologous protein(CHOP).The results were analyzed by sNK-q test.Results Compared to Tm group(cell viability 0.1673±0.0213,apoptotic rate 62.7050±1.4056),The cell viability of interventional groups(5%0.5295±0.0373,10%0.5843±0.0428,15%0.6274±0.0324)increased significantly(P<0.05);and the apoptotic rate(5%47.8733±2.8166,10%46.3366±1.2748,15%39.8833±1.0524)reduced significantly(P<0.05).The protein expressions of GRP 78(5%2.1228±0.2251,10%1.3293±0.9443,15%;15%0.0931±0.1168)and CHOP(5%1.1776±0.2927,10%0.7290±0.1708,15%0.6577±0.1883)of interventional groups reduced significantly compared with Tm group(GRP78 2.9149±0.5355;CHOP 1.6611±0.2913)P<0.05.Condusions ZBPYR serurn could increase the cell viability of Neuro2a cells treated with Tm and inhibit cell apoptosis.Thereby it may have neuroprotective effects,and the mechanism may be associated with the inhibition of ER stress and apoptosis pathway.

Objective: To study the relationship between primary tooth discoloration and caries in preschool children. Methods: 675 preschool children enrolled from 5 preschools in Suzhou City, China were examined for dental caries and tooth surface stain. Parents completed the questionnaires about their children's eating habit and living habit. The relationship between primary tooth discoloration and caries was analyzed with the respect to diet, hygiene, and the use of medicine or medical supplements. Results: Of the 675 children, 117(17. 3％; 52 boys and 65 girls) had tooth discoloration with no significant differences between gender(P＞ 0. 05). In the 117 children with tooth discoloration, 36(30. 8％) had dental caries, and in the 558 children without tooth discoloration 325 had caries (58. 2％, between the 2 groups, P＜ 0. 05). The incidence of discoloration was related with the frequency of consuming pigmented foods, vegetable and Chinese herbal medicines(P＜ 0. 05). The frequency of brushing teeth, use of water purifier and the water intake quantity were not significantly associated with discoloration of the teeth(P＞ 0. 05). Conclusion: The discoloration of primary teeth was negatively correlated with caries in primary teeth. Intake of pigmented food and medicine, vegetable and Chinese herbal medicine is related to tooth discoloration in preschool children.

OBJECTIVEThe primary goal of our study was to evaluate and predict the epidemiological trend of pneumoconiosis.

METHODSWe established a new database on new-diagnosing cases of pneumoconiosis in Nanjing during 1955-2007. The database was analyzed by using SAS9.1.3 statistical software, Data sequence was stabilized by using the process of differencing. Goodness of Fit Test verified that the residual-error sequence was white noise sequence. We determined the Autoregressive Integrated Moving Average models (ARIMA models) as an appropriate model. By Taking advantage of back-substitution model, we predicted new cases of pneumoconiosis during 2008-2012. We then compared the predicted value with the actual value to test and verify the predicting function.

RESULTSWe finally had chosen out ARIMA (2, 1, 0) models to fit the original sequence, which led to the results that the observed values are basically comparable with the predicted values. The past 5-year predicted-value was similar to the actual value. We then built a new model by new cases during 1955-2012, predicting that the trend of pneumoconiosis in the next 5 years will tend to approach plateau with approximately 10∼13 new cases per year.

CONCLUSIONARIMA models is suitable for fitting large sample series of new diagnosed pneumoconiosis over the years and for the predicting the incidence of pneumoconiosis.

OBJECTIVETo investigate the effect of Chinese drugs for tonifying Shen on the bioactivity, cell proliferation, invasion and differentiation of human cytotrophoblast of early pregnancy.

METHODSThe human early pregnant cytotrophoblast was cultured in vitro, and treated with saline (as blank control) and drug containing serum in different concentrations (5%, 10% and 20%) respectively. The changes of morphology, proliferation and invasive capacity of cells were examined by scanning electron microscopy, MTT method, flow cytometry, Transwell invasive assay at 24 hrs, 48 hrs and 72 hrs after treatment.

RESULTSAfter cells being cultured with drug containing serum, the cytotrophoblast became abundant in microvilli, with more and prolonged pseudopodia. The cell absorbency in 490 nm wave length increased significantly (P < 0.01), cells of sub-G1 and G2/M phase obviously decreased and that of S phase increased (P < 0.01), and the cells penetrated through PET membrane in each visual field significantly increased (P < 0.01).

CONCLUSIONChinese herbs for tonifying Shen could promote the proliferation and invasive capacity of cytotrophoblast and might influence its differentiation.

Objective:To investigate the therapeutic effects of bridge internal fixation system on the treatment of periprosthetic femoral fracture of Vancouver type B1.Methods:From June 2013 to October 2018, 10 patients with periprosthetic femoral fracture of Vancouver type B1 were treated by bridge internal fixation system at Department of Orthopedics, Zhucheng People's Hospital Affiliated to Weifang Medical College. They were 3 males and 7 females, aged from 65 to 84 years (average, 73.6 years). All patients had received hip replacement due to femoral neck fracture, including 6 hemi-hip replacements and 4 total hip replacements. Fracture had occurred in 9 cases after the primary hip replacement and in one case after revision. The time from primary hip replacement to the present surgery ranged from 1.5 to 4.0 years (average, 2.5 years). Recorded were operation time, intraoperative blood loss, fracture healing time, hip joint function and complications at the last follow-up.Results:In this group, operation time ranged from 65 to 114 min (average, 82 min), intraoperative blood loss from 110 to 320 mL (average, 145 mL). The 10 patients were followed up for 12 to 18 months (average, 15 months). Their X-ray films showed that bony union was achieved in all after 3 to 6 months (average, 4.3 months). According to their hip Harris scores at the last follow-up, 7 cases were rated as excellent, 2 as good and one as fair. Follow-ups revealed no loosening or breakage of implants, infection, femoral prosthesis loosening, fracture or femoral prosthesis displacement.Conclusion:Bridge internal fixation system is a good way to treat periprosthetic femoral fracture of Vancouver type B1, leading to satisfactory short-term outcomes and fine functional recovery.

OBJECTIVE: To assess the practical and health economical values of non-invasive prenatal test (NIPT) in Changsha Municipal Public Welfare Program. METHODS: A retrospective analysis was carried out on 149 165 women undergoing NIPT test from April 9, 2018 to December 31, 2019. For pregnant women with high risks, invasive prenatal diagnosis and follow-up of pregnancy outcome were conducted. The cost-benefit of NIPT for Down syndrome was analyzed. RESULTS: NIPT was carried out for 149 165 pregnant women and succeeded in 148 749 cases (99.72%), for which outcome were available in 148 538 (99.86%). 90% of pregnant women from the region accepted the screening with NIPT. 415 (0.27%) were diagnosed as high risk. Among these, 381 (91.81%) accepted amniocentesis, which led to the diagnosis of 212 cases of trisomy 21 (PPV=85.14%), 41 cases with trisomy 18 (PPV=48.81%) and 10 cases with trisomy 13 (PPV=20.83%). The sensitivity and specificity of NIPT for trisomy 21, trisomy 18 and trisomy 13 were (97.70%, 99.98%), (97.62%, 9.97%) and (100%, 99.97%), respectively. In addition, 213 and 30 cases were diagnosed with sex chromosomal aneuploidies (PPV=46.2%) and other autosomal anomalies (PPV=16.57%), respectively. For Down syndrome screening, the cost and benefit of the project was 120.79 million yuan and 1,056.95 million yuan, respectively. The cost-benefit ratio was 1: 8.75, and safety index was 0.0035. CONCLUSION NIPT is a highly accurate screening test for trisomy 21, which was followed by trisomy 18 and sex chromosomal aneuploidies, while it was less accurate for other autosomal aneuploidies. The application of NIPT screening has a high health economical value.

OBJECTIVETo investigate the etiology of severe hand-foot-mouth disease (HFMD) in children in Henan province.

METHODSA total of 244 HFMD cases admitted to a hospital in Zhengzhou from April to June of 2014 were recruited for research sampling, Real-time RT-PCR, virus isolation, VP1 sequencing and alignment methods were used to test the enterovirus-related etiology. SPSS 17.0 was used in performing statistical analysis.

RESULTSThere were 109 severe and 135 mild cases among all the 244 HFMD cases. The number of enterovirus positive stool samples was 229, with positive rate as 93.85%. EV71, Cox A16 and Cox A10 made up 83.84%, 5.68% and 8.30% of the enterovirus etiologicy, strains, respectively. EV71 infection caused 8 HFMD cases with heart-lung failure and 2 death, Cox A10 infection led to 1 HFMD case with heart-lung failure and death. There were statistically differences seen regarding the enterovirus infection rates between severe and the mild HFMD cases (χ(2)=5.312,P=0.021). Statistically significant difference was seen in the constituent ratio of EV71, Cox A16 and the others by Fisher' s exact test (P=0.048). There was statistically significant difference seen between the cardiorespiratory failure rate and the fatality rate by EV71 and Cox A10 infection (χ(2)=0.051,P=0.821; χ(2)=2.198,P=0.138). Cox A10 strains idenfied in Henan in 2014 belonged to genotype 6. The rates on homology of nucleotide and amino acid among the Cox A10 strains in Henan in 2014 were 94.3%-99.7% and 96.3%-100.0% respectively.

CONCLUSIONSEV71 still remained the most common pathogen that causing severe HFMD in children, with the increasing Cox A10 percentage in the pathogens spectrum of HFMD infection. Cox A10 strains in Henan in 2014 belonged to genotype 6. Genotype 6 Cox A10 had appeared and widely distributed in Henan for long time, but not yet variated or reconstructed. Cox A10 infection could lead to cardio-respiratory failure thus called for the monitoring program on non-EV71 and non-Cox A16 enterovirus, especially Cox A10 to be strenthened.
