Objective Attempting to find a reliable method for assessing the patient's ability to tolerate carotid artery occlusion. Methods The temporary balloon occlusion (TBO) test of carotid artery was performed for 20 patients who might have carotid artery manipulated or permanently occluded. Transfemoral artery Seldinger's catheterization was used to introduced the temporary balloon occlusion catheters into the vessels of the concern. Neurologic testing was performed continuously by the attending neurologist. Transcranial Doppler ultrasonography (TCD) and carotid artery stump pressure (SP) were measured contiuously during the TBO. The collateral circulation of Willis circle was observed with DSA. Results Out of the 20 cases, one failed during the TBO because of CCA dissection caused by catheterization, another one failed because of a neurologic defect occurring before the balloon was inflated, the others went through the test uneventfully. Two cases finished the test before the approved schedule because neurologic defects appeared 34 min and 27 min after the vascular occlusion, respectively. These two patients were proved unable to tolerate carotid artery sacrifice. The other 16 cases passed the 45 minutes TBO. Their mean velocity of ipsilateral middle cerebral artery fell 36%?18%. Their SP is (53.76?21.49) mmHg(30-87). Adequate collateral circulation in Willis circle was observed by DSA in all cases except the two who failed with the TBO. Conclusions TBO is a safe and reliable method for assessing the patient's ability to tolerate carotid artery occlusion. We suggest it should be a routine examination prior to carotid manipulations.

Objective To evaluate the clinical value of pre-operative double embolization for nasopharyngeal angiofibroma. Methods Digital subtraction angiography(DSA) was carried out in 7 cases of nasopharyngeal angiofibroma. In six cases,the supplying arteries originated from the maxillary artery and the branches arising from internal carotid artery underwent double embolization-direct percutaneous puncture embolization and selective embolization of blood supplying arteries. In another case,the supplying artery originated from maxillary artery was only undertaken selective embolization for the feeding arteries. Results All the tumor masses reduced in vonlume obviously or even disappeared on the angiography after embolization. Conclusions Pre-operative double embolization for nasopharyngeal angiofibroma could be a necessary additional treatment method. (J Intervent Radiol,2006,15: 342-344)

Objective To investigate the expression of occludin in the intestinal epithelial cells of neonatal rats with necrotizing enterocolitis ( NEC) . The influence of vitamin D on NEC and the expression of occludin was also explored. Methods Sixty neonatal Wistar rats from different litters were divided into four groups 48 hours after birth:10 in the breast-fed+ control group,10 in the breast-fed +vitamin D group,20 in the NEC+ control group and 20 in the NEC+ vitamin D group. In groups with NEC,neonatal rats were sep-arated from their mothers and treated with rat milk substitute+hypoxia+hypothermia. In groups with vitamin D treatment,paricalcitol was given through intraperitoneal injection 30 minutes before,one day and two days after the induction of NEC. The tissue was harvested from the ileum of the rats 72 hours after induction of NEC. Microscopically,the tissue was assessed according to the Nadler scoring system. The expression and location of occludin was observed after immunofluorescence staining. Western blotting was performed and quantified to compare the expression of occludin among groups. Results In NEC rats,the intestinal structure was destructed. Separation of the submucosal or muscular layer,discharge or disappearance of the villa was accompanied by necrosis of the intestinal cells. Vitamin D treatment could significantly alleviate those chan-ges,with the Nadler score 1. 70 ± 0. 21 compared to 2. 90 ± 0. 23 without vitamin D treatment ( P<0. 01 ) . The expression of occludin was decreased in NEC rats and vitamin D could partly rescue this decrease (P<0. 01). The distribution of occludin was sparse and discontinuous in NEC rats while after vitamin D treatment,the distribution was maintained even and continuous. Conclusion The expression of occludin in intestinal epithelial cells is significantly reduced in NEC rat. Vitamin D treatment may inhibit the development of NEC by maintaining the expression of occludin.

Objective To report our experience in the embolization of the high-flow vascular lesion in the head and neck by direct percutaneous puncture. Methods Eleven cases of high-flow vascular lesion in the head and neck (8 cases of central hemangioma of the jaws and 3 cases of juvenile nasopharyngeal angiofibroma) were included in this study group. The patients of central hemangioma of the jaws were embolized with coils by a 14-gauge needle, and the fibered coils were placed directly into the center of the intraosseous AVM. The patients of juvenile nasopharyngeal angiofibroma were embolized with NBCA by a No.7 needle. The procedure was under the guidance of DSA machine (Philips V3000). Results The acute arterial bleeding in patients with central hemangioma of the jaws from the extraction of the tooth was controllable, and the pericoronal oozing of bleed disappeared in the 9-24 months follow-up. The juvenile nasopharyngeal angiofibromas were resected without blood transfusion after the embolization. Conclusion The embolization of the high-flow vascular lesion in the head and neck by direct percutaneous puncture was effective and safe, however the longer follow-up was expected.

Objective To investigate the association between serum 25(OH) D levels and the inci-dence of early-onset sepsis(EOS) in the very low birth weight infants(VLBWI) and the gestational age be-low 34 weeks. Methods The cord blood of 159 VLBWI were collected between January and December 2017,including 31 clinically diagnosed EOS and 128 non-EOS patients. Serum 25(OH)D<10 ng/ml was de-fined as severe vitamin D deficiency,25(OH)D 10 to 20 ng/ml as vitamin D deficiency,25(OH)D 20 to 30 ng/ml as vitamin D insufficiency and 25(OH)D >30 ng/ml as vitamin D sufficiency. Results There were no differences in gender,gestational age,birth weight and Apgar score between the EOS group and the non-EOS group(P>0. 05). Serum 25(OH) D was(9. 08 ± 4. 21) ng/ml in the EOS group and(11. 91 ± 5. 37) ng/ml in the non-EOS group(P＝0. 007). The rate of severe vitamin D deficiency was 67. 7%(21/31)in the EOS group and 41. 4%(53/128) in the non-EOS group. The rate of vitamin D deficiency was 32. 3%(10/31)in the EOS group and 52. 3%(67/128)in the non-EOS group. But there was no difference of vitamin D deficiency distribution in the two groups(P＝0. 152). The cut-off value of serum 25(OH)D level in predic-ting EOS was 10. 06 ng/ml. Conclusion The incidence of vitamin D deficiency is as high as 95%,calling for urgent attention on vitamin D supplementation in those VLBWI. Low 25(OH)D level( <10 ng/ml)might be predictive of EOS.

Objective To study the diagnostic value of abdominal ultrasound for neonatal necrotizing enterocolitis (NEC). Method Neonates diagnosed with NEC admitted to Department of Shengjing Hospital from January 2016 to December 2018 were retrospectively analyzed. They were assigned into NEC stage Ⅱ group and NEC stage Ⅲ group based on the modified Bell-NEC grading criteria. Meanwhile, according to the timing of imaging examination, the patients were assigned into the group within 7 days after the onset of NEC and the group between 8 and 14 days. They were then grouped into conservative treatment group and surgery group. The difference between abdominal X-ray plain film and abdominal ultrasound in the performance of diagnosing NEC within groups were compared. Result A total of 60 patients with NEC were studied, including 38 with NEC stage Ⅱand 22 with NEC stage Ⅲ, among them 14 patients underwent surgery, others had conservative treatment. The average gestational age was (33.3±3.2) weeks and the average birth weight was (2047±831) g. The positive detection rate of pneumatosis intestinalis and hepatic portal venous gas by abdominal ultrasound vs. X-ray plain film in≤7 d group were 38.3％ (23/60) vs. 15.0％ (9/60) (P=0.004) and 15.0％(9/60) vs. 1.7％ (1/60) (P=0.008), respectively, indicating the positive detection rate of abdominal ultrasound was significantly higher than that of X-ray within 7 d after the onset of NEC. However, there was no significant difference in the detection rate between abdominal ultrasound and abdominal X-ray 8～14 d after the onset of NEC (P>0.05). The detection rate of intestinal wall thickening and peritoneal effusion by abdominal ultrasound together with the detection rate of intestinal dilatation and free gas in abdominal cavity by abdominal X-ray plain film in the conservative treatment group were significantly lower than those in the surgery group (P<0.05). Conclusion Abdominal ultrasound can help detecting the characteristic features of NEC (pneumatosis intestinalis and hepatic portal venous gas) in time, which has great value for early diagnosis and assessing severity.

Due to the drawbacks of the single function for the existing pedometers, this paper proposes an intelligent fitness partner based on the acceleration and photoelectric sensors.Through low-cost and single-chip three axles acceleration sensors MMA7260, it extracts and analysis the human's sports information. Furthermore, it detects and analyses the human's heart rate signal, by using the photoelectric sensor. Microcontroller PIC18F4520 is used to realize the algorithm of adaptive step counting model, and the heart rate detection circuit is also set up. The experimental results show that the proposed fitness partner can accurately display the heart rate wave of the testee, and the accurate rate is above 90%.

Objective:To compare the head magnetic resonance imaging (MRI) changes and the distribution of pathogens of purulent meningitis in premature and full term infants.Methods:This retrospective study assessed clinical data in 43 cases of neonatal purulent meningitis with positive blood or cerebrospinal fluid bacterial culture admitted to the Neonatal Ward of Shengjing Hospital of China Medical University from January 2012 to November 2019.According to the gestational age, those patients were divided into the premature infant group and the full term infant group.The general situation, head MRI and pathogen characteristics of both groups were compared.Results:The incidence of premature rupture of fetal membranes in the premature infant group was higher than that in the full term infant group [50.00%(13/26 cases) vs.5.88%(1/17 cases)], the rate of cesarean section in the premature infant group was higher than that in the term infant group [61.54%(16/26 cases) vs.23.53%(4/17 cases)], and there were significant difference between the 2 groups ( χ2=9.011 and 5.969, respectively, all P<0.05). There was no significant difference between 2 groups in age of onset [(9.8±7.0) d vs.(8.9±5.5) d], diagnosis[(13.0±7.1) d vs.(10.2±6.1) d] and examination [(16.1±7.9) d vs.(13.1±6.5) d] (all P>0.05). The top 3 pathogens were Klebsiella pneumonia ( K. pneumoniae) in 14 cases, Escherichia coli ( E. coli) in 11 cases and Streptococcus agalactiae (GBS) in 7 cases. K. pneumoniae was the most common pathogen in premature infants, and GBS was the most common pathogen in term infants.In the first MRI, white matter injury (WMI) was the most common disease (19 cases), the abnormal rate of MRI in the premature infant group was 65.38% (17/26 cases), the incidence of intracranial hemorrhage in the premature infant group was higher than that in the term infant group, the abnormal rate of MRI in the term infant group was 52.94% (9/17 cases), and the incidence of cerebral infarction in the term infant group was higher than that in the premature infant group.The MRI positive rates of meningitis caused by K. pneumoniae, E. coli and GBS were 57.14% (8/14 cases), 72.73% (8/11 cases) and 71.43% (5/7 cases), respectively.Infants with K. pneumoniae infections suffered from the main complications of WMI and intracranial hemorrhage.Infants infected with E. coli were prone to WMI in the early stage and hydrocephalus in the late stage.Infants with GBS were prone to WMI and cerebral infarction in the early stage and cerebromalacia in the late stage. Conclusions:There were some differences in the distribution of pathogenic bacteria and head MRI changes between premature infants and term infants, and head MRI of purulent meningitis caused by different pathogenic bacteria.A thorough understanding of the distribution of pathogens and the characteristics of head MRI in premature and full term infants contributed to the early diagnosis, treatment and prognosis of this disease.

Objective To explore the effects of Bushen Jiedu Formula combined with auricular pressure by coxherb seeds on cancer pain and quality of life in patients with advanced colorectal canc-er.Methods A total of 120 patients with advanced colorectal cancer admitted to our hospital from June 2019 to May 2023 were included in the study,and were randomly divided into two groups.The control group(60 cases)received routine nursing care and the"three-step"analgesic method to in-tervene pain,while the observation group(60 cases)received treatment with Bushen Jiedu Formula combined with auricular pressure by coxherb seeds on the basis of the control group.Both groups were treated for one month.The Numerical Rating Scale(NRS)score,the therapeutic effect,the quality of life(QOL)score and the occurrence of adverse reactions were compared between the two groups before and after treatment,and the levels of substance P(SP),β-endorphin(β-EP)and prostaglan-din E2(PGE2)of the two groups before and after treatment in serum were detected.Results After treatment,the NRS score and the levels of SP,β-EP and PGE2 in the observation group were(2.23±0.64),(11.51±2.64)ng/mL,(78.64±9.46)ng/L and(41.90±6.32)ng/L,re-spectively,which were lower than(2.87±1.25),(15.64±2.42)ng/mL,(101.29±11.26)ng/L and(78.63±10.17)ng/L,respectively of the control group(P＜0.05).The total effective rate and QOL score of the observation group were 90.00％and(51.92±5.66),which were higher than 75.00％and(43.58±5.12),respectively of the control group(P＜0.05).There was no signifi-cant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclu-sion The combination of Bushen Jiedu Formula and auricular pressure by coxherb seeds can obvi-ously improve the cancer-induced pain of patients with advanced colorectal cancer,improve their quality of life,and have good safety.
