Objective of the study is to explore how to apply ARIMA model in prediction of outpatients headcount,describe the modeling process,build the prediction model,and verify its applicability to serve decision making for hospital management.Methods Data originates from the outpatient statements of the HIS integrated statistics and management decision making support system.The data collection ranges from the monthly outpatients headcount from 1999 to 2005,in which the monthly data from 1999 to 2004 were used to build the time sequence model,and those of 2005 to verify the model so built.The statistic software was programmed with SPSS13.0.Results The ARIMA(1,0.1)(0,1,1)12 model was built by megns of model identification,parameter estimate.inspection/diagnosis,and model appraisal.This model features high fitting precision,as the relative error or outpatients headcount for the year is 6.85%,and that for the months ranges from-3.15%to-9.80%,with the actual values falling within the 95%upper and lower thresholds of the prediction results.Conclusion This study proves that ARIMA model fits the purpose of outpatients headcount prediction.In the meantime,prediction of such headcount should also take into account such factors as the data volume,hospital environment and patient satisfaction.

Objective To investigate the effects and mechanism of hypoxia on the growth and invasion of human cervical cancer Hela cells. Methods Hypoxia microenvironment was mimicked by cobalt chloride (CoCl2), in which the growth of Hela cells were determined by MTT method, the migration ability was detected by scratch test, and the expressions of HIF-1αand Vimentin protein were measured by immunofluorescence. Results The growth of Hela cells treated with 150 μmol/L of CoCl2 for 6 h was promoted. The migration ability in hypoxia group at 48 h was significantly higher than that in ordinary oxygen group. The expressions of HIF-lαand Vimentin in Hela cells in hypoxia group were significantly higher than those in ordinary oxygen group. There was significantly positive correlation between the expressions of HIF-1α and Vimentin (P < 0.05). Conclusion Hypoxia could promote the expression of HIF-lα, which then could up-regulate the expression of Vimentin , and finally enhanced the ability of invasion and metastasis of Hela cells.

Objective To investigate the concentrations of serum N-terminal brain natriuretic peptide (NT-pm BNP) and high-sensitivity C-reactive protein (hs-CRP) of acute exacerbation of chronic obstrnctive pulmonary disease(AECOPD) patients treated by bi-level positive airway pressure(BiPAP) for with respiratory failure.Methods A total of 100 respiratory failure in patients with AECOPD were divided into study group and control group,and 50 cases of each group.Patients in study group were received the conventional treatment(anti infection,diastolic bronchial,cough and phlegm and oxygen therapy) combined with BiPAP therapy,while in control group were received the conventional treatment.Blood samples were drawn at beginning and 3 d later.Serum hs-CRP and NT-pro BNP levels were determined,and the expenses and duration of hospitalization of two groups were compared.Result After treatment,the level of serum NT-pro BNP in study group and control group were (105.79 ± 4.56) ng/L and (113.33 ± 3.26) ng/L,and the difference was statistically signifi cant (t =3.03,P ＜ 0.05).The serum hs-CRP levels were (10.83 ± 16.35) mg/L and (26.39 ± 26.87) mg/L in study and control group,and the differences were statistically significant (t =-3.44,P ＜ 0.05).The expenses and duration of hospitalization in study group were both less than those in control group((11.15 ± 1.86) d vs.(12.78±2.25) d;(6 659.11 ±1 609.49) yuan vs.(8 031.31 ±1 449.79) yuan;t=-3.87,-4.38;P ＜0.05).Conclusion Early BiPAP therapy in AECOPD patients with respiratory failure in patients is showed that NT-pro BNP and hs-CRP levels faster decrease and disease is recovery remission,which suggests that NTpro BNP or BNP for AECOPD patients and respiratory failure condition monitoring,clinical efficacy have some clinical value.

ObjectiveTo explore the clinical value of ultrasound and MRI in diagnosis of simple fetal indirect hernia.MethodsA total of 671 558 fetuses were examined in maternal and child healthcare hospital of Hubei from February 2003 to February 2015. Once inguinal hernia or testicular tumors was suspected, MRI examination was performed after prenatal ultrasound. Final diagnosis was confirmed by postnatal follow-up. The ultrasonographic characteristics of fetal indirect hernia were compared with prenatal MR image characteristics and postnatal follow-up results.ResultsThree cases were conifrmed after birth. The simple fetal indirect hernia was uncommon clinical entity which occurred during 3rd trimester. The ultrasonic characteristics in prenatal period were: (1) Right enlarged scrotum was iflled with heterogeneous lesion; intestinal peristalsis within the scrotum was found in real-time ultrasonography. (2) The contralateral testis in left scrotum and penis could be found. MRI could display the characteristicsof indirecthernia contents and its extension from abdominal cavity intoinguinalregion, which may help diagnose fetal simple indirect hernia. One case of fetal indirect hernia was misdiagnosed as testicular tumors, which was correctly diagnosed by MRI.ConclusionsThe simple fetal indirect hernia can be prenatally diagnosed by characteristic ultrasonic features, which can present with abnormal mass ininguinalregion. Prenatal ultrasound is the primary screening method of fetal indirect hernia. MRI can serve as a supplement approach. The combination of US and MRI can further improve the diagnostic accuracy of fetal indirect hernia.

Objective To investigate the radiosensitiation effect of berberine on human nasopharyngeal carcinoma ( NPC) in hypoxia condition and explore the underlying mechanisms. Methods MTT assay, clonogenic assay and flow cytometry were performed to analyze cell proliferation, colony formation and apoptosis, respectively. Male nude mice inoculated subcutaneously with CNE-2 cells were used to examine the radiosensitization effect of berberine in vivo. The expressions of HIF-1α and VEGF were assessed by Western blot. Results Berberine efficiently inhibited the proliferation of CNE-2 cells in time-dependent and dose-dependent fashions with an IC50 of ( 14?9 ± 2?2 ) μmol/L. Clonogenic survival assay showed that berberine ( 5 μmol/L ) sensitized CNE-2 cells to ionizing radiation in hypoxia and its SERD0 was 1?27. Under hypoxic condition, berberine alone (5, 15 μmol/L) could induce apoptosis (t=5?01, 9?02,P<0?05) and it further promoted 8 Gy radiation-induced apoptosis (t =5?31, 9?91,P <0?05). Moreover, berberine significantly delayed the tumor growth in the combination group (berberine +irradiation) compared with the mice received irradiation alone or PBS (t =2?96, 14?52, P <0?05). Immunobloting assay showed that berberine inhibited the upregulation of HIF-1α and VEGF induced by hypoxia in CNE-2 cells. Conclusion Berberine confers radiosensitivity on hypoxic NPC in vitro and in vivo, which is probably associated with the downregulation of HIF-1α and VEGF expressions.

Objective To explore ways to decrease peripheral vascular complications during parenteral nutrition through peripheral veins. Methods According to the support sequences of giving peripheral parenteral nutrition, ninty perioperative cases were randomly divided into low(20. 3 kPa·h-1 ),medium(27. 1 kPa·h-1 ) and high(33. 9 kPa·h-1 ) osmotic pressure rates(n=30 in each group). The infusion pump was used to control the rate of infusion. The total parenteral nutrient was infused through BD24G venous indwelling needles. The pain ratings at injection sites were evaluated after parenteral nutrition everyday,the incidences of phlebitis were observed three days later after removing the indwelling needles. ResultsUnder the low osmotic pressure,the pain was mild,while for the medium osmotic pressure,the pain became more obvious. The pain was aggravated obviously under high osmotic pressure. There were only two cases of over grade-II phlebitis under low osmotic pressure rate,9 cases under medium osmotic pressure rate and 14 cases under high osmotic pressure rate, in which a grade-Ⅲ phlebitis developed. Conclusion Decreasing the osmotic pressure rate through peripheral venous is an effective method to avoid or reduce the incidences of peripheral vascular complications with the peripheral parenteral nutrition support.
