Objective To investigate the relationaship between liver cirrhosis patients comibined with infection or death and intestinal permeability (IP)test.Methods 48 patients with liver cirrhois and 16 healthy volunteers were enrolled in the Af-filiated Hospital of Yan’an University during 2 years from 2013 to 2014 in this prospective study.Clinical data of patients were analyzed.LMR (IP index)were caculated and dectected by HPLC differental method.Serum LBP,IL-6 and I-FABP were determined by ELISA.Patients were followed for 1 year and assessed fro survival and the occurrence of infections.Re-lated factors with IP index were analyzed by Spearman’s rho.ROC curve,kaplan-meiser curve,cox regression were used to analyze related factors with the infection-free survival.Results IP index were increased in 40 (83.3%)patients with liver cirrhosis,compared with 4 increased IP index in healthy controls (χ2=19.006,P=0.001).IP index were correlated with al-bumin,IL-6,INR,bilirubin and Child-Pugh (CTP)scores by Spearman’s rho anaylsis (rs=-0.339~0.485,all P<0.05). 20 (41.7%)liver cirrhosis patients developed infection in the one year follow-up.There were signigicant differences in asci-tes (14 vs 18),CTP scores [9(5~14)vs 10(7~14)],MELD scores [12(7~27)vs 17(9~25),IL-6 [40(10~1 200)vs 60 (10~1 800)pg/ml]and I-FABP [1 160(800~8 600)pg/ml vs 4 130(1 520~8 060)pg/ml]between non-infected cirrhosis and infected cirrhosis patients (χ2=8.400,Z=-3.310~-2.160,all P<0.05).It was found that MELD>9,acites,I-FABP>1 728 pg/ml were independent factors of infection-free survial in liver cirrhosis patients by COX regression (all P<0.05).Conclusion Although increased IP was higher in liver cirrhosis,and it failed to predict infection-free survial in liver cirrhosis patients.

Objective To investigate clinical features of lower motor neuron lesion (LMNL) caused by the single level lower thoracic disc protrusion (LTDP),and to observe clinical outcomes of surgical treatment.Methods Between January 1997 and December 2009,17 patients with LMNL caused by single level LTDP underwent en bloc resection of the superior articular process,Cave-in 360° circumferential decompression and internal fixation in our hospital.MRI and CT scans were taken to confirm lesion levels:T10-11 in 4 patients of whom 3 had patellar clonus and ankle clonus,T11-12 in 5 patients of whom 4 had ankle clonus,and T12L1 in 8 patients who only had positive Babinski sign.The neurologic status was assessed using the Japanese Orthopaedic Association (JOA) scoring system.The muscle strength of the tibialis anterior was assessed using the Manual Muscle Test (MMT).Sagittal Cobb angle and cross-sectional area of the dural sac at the level of maximal compression in MRI were also observed.Results All patients were followed up for 22 to 76 months (average,48.6 months).The mean JOA score increased from preoperative 5.88±1.11 to 9.53±0.94 at final follow-up (t=16.143,P＜0.05).The muscle strength of the tibialis anterior recovered to more than grade 4 in all patients.Postoperative Cobb angle was unchanged compared with that before operation.MRI indicated that the cross-sectional area of the dural sac at the level of maximum compression increased from preoperative 35.8±7.3 mm2 to postoperative 132.9±6.5 mm2 (t=70.78,P＜0.05).Conclusion LMNL can be caused by LTDP.The eu bloc resection of the superior articular process,Cave-in 360° circumferential decompression and internal fixation can provide a satisfactory decompression effect and marked recovery of neurological function.

Objective To investigate the epidemiological and clinical characteristics and prognosis of 31 children with hand foot and mouth disease(HFMD) complicated with acute flaccid paralysis(AFP).Methods Thirty-one HFMD children complicated with AFP served as study objective,who were admitted to Tangshan Maternity and Children Health Hospital from Jun 2011 to Dec 2014.The clinical manifestations and follow-up outcomes of 31 children with HFMD followed by AFP were retrospectively reviewed.Results Participants in this study consisted of 31 children(16 males,15 females,age from 3 months to 9 years) who met the criteria for HFMD with AFP.Among the 31 cases,27(87.1％)cases were less than 3 years old and 29(93.5％) cases were from countryside.Eleven cases (35.5％)were infected by enterovirus 71,1 case (3.2％) was infected with coxsackieviruses A16 and 19 cases(61.3％) were infected by other enteroviruses.AFP developed(7.1 ±2.9) days after the onset of fever and progressed to maximum severity within 1-2 days.All of the cases presented with fever and skin rash,38.7％ cases presented with limbs tremor and 87.1％ cases presented with startle and skip.Besides AFP of limbs, 100％ cases complicated with encephalitis.Thirty-one cases showed poliomyelitis-like syndrome(20 cases with one flaccid limb,5 cases with lower limbs,4 cases with upper limbs and 2 cases with left hemiplegia).In these cases, the muscle power varied from level 0 to level 4.The muscle strengthen and muscle tone in 21 patients were recovered within 2 weeks,and the other cases showed recovery 2 to 3 weeks later.After four weeks, the muscle strengthen in 19 cases recovered to 5 level(10 cases with single lower limb,5 cases with single upper limb,3 cases with two lower limbs and 1 case with two upper limbs).Conclusion HFMD complicated with AFP most commonly occurs in children aged less than 3 years old.The majority of cases were from countryside.Enterovirus 71 is still relatively common pathogen.All the 31 cases complicated with encephalitis.Cases clinically presented one flaccid limb, lower limbs, upper limbs and hemiplegia.AFP may be to some degree reversible in HFMD cases.In most cases described here, paralysis occurred in a single lower extremity and recovered more rapidly than those with two fimbs affected or with single upper extremity impairment.

Objective To verify the feasibility of discriminating tissue types in the anterior approach of the cervical spine by the Electrical impedance (EI) and decrease the rate of severe complications.Methods Six New Zealand white rabbits and 6 mini-pigs were performed standard anterior cervical surgery.The esophagus,carotid artery,tracheal cartilage,annular ligaments of trachea,longus colli muscle and anterior longitudinal ligament are classified as the prevertebral group;The cortical bone,cancellous bone,anulus fibrosus and nucleus pulposus are classified as the vertebral group.Once all the tissues were exposed completely,over the frequency range of 200-3 000 kHz (the frequency points were 200 kHz,400 kHz,600 kHz,800 kHz,1 000 kHz,2 000 kHz,3 000 kHz),the in vivo EI of prevertebral group and vertebral group were measured by a probe and a precision inductance-capacitance-resistance (LCR) meter;then the data were analyzed with IBM SPSS Statistics 22 software.At every frequency,Kruskal-Wallis test followed by all pairwise multiple comparisons was applied for all the four groups (the prevertebral group of rabbits,the vertebral group of rabbits,the prevertebral group of mini-pigs,and the vertebral group of mini-pigs),respectively.P values ＜ 0.05 were considered statistically significant.Results At every frequency,the results of Kruskal-Wallis test for all the four groups were significant,and the results of multiple comparisons were as follows.(1) In both miniature experimental animals and large experimental animals,the EI of the vertebral group tissues was significantly different at every investigated frequency (multiple comparisons).(2) In the miniature experimental animals,the EI between longus colli muscle and esophagus,carotid artery and annular ligaments of trachea,and tracheal cartilage and anterior longitudinal ligament had no significant difference at any frequency (multiple comparisons);significant difference could not be detected in the EI between anterior longitudinal ligament and annular ligaments of trachea at the frequencies of 2000-3 000 kHz (multiple comparisonsk) and could be detected at the frequencies of 200-1 000 kHz (multiple comparisons);for comparison of all other paired tissues of prevertebral group there were significant differences at all frequencies (multiple comparisonsk).(3) In the large experimental animals,the EI between longus colli muscle and esophagus,carotid artery and annular ligaments of trachea,and tracheal cartilage and anterior longitudinal ligament had no significant difference at any frequency (multiple comparisons),the same was true for the EI between annular ligaments of trachea and esophagus,carotid artery and anterior longitudinal ligament,and longus colli muscle and annular ligaments of trachea at the frequencies of 800-3 000 kHz,3 000 kHz and 3 000 kHz (multiple comparisons),respectively;for comparison of all other paired tissues of prevertebral group there were significant differences at all frequencies (multiple comparisons).Conclusion At certain frequencies,the EI among tissues was significantly different and could discriminate tissues in the anterior approach of the cervical spine.

To understand the family sex education for young children in rural areas of Sichuan province and analyze the influencing factors. A multi-stage random sampling method was used to select 2246 parents of kindergarten children from rural areas in Sichuan province for a questionnaire-based survey.The Chi-square test and Logistic regression model were used for data analysis. It was found 1132(52.33%)parents had implemented family sex education for young children and 1031(47.67%)had not.Young children having asked sex-related questions(=1.536,95%=1.257-1.878),parents thinking that early childhood sex education is necessary(=3.691,95%=2.029-6.717),and parents having the intention to know early childhood sex education(=1.700,95%=1.274-2.269),and kindergarten having implemented early childhood sex education(=3.316,95%=2.515-4.372)were promoting factors for parents to conduct early childhood sex education,whereas a total annual household income at the middle level(=0.664,95%=0.456-0.968)was a hindering factor for parents to conduct early childhood sex education. Parents of young children in rural areas of Sichuan province have poor awareness of sex education,and the proportion of parents who have never conducted sex education for children is high.The total annual income of the family,whether the children have asked about sex-related questions,parents' attitude towards early childhood sex education,and whether the kindergarten has conducted the early childhood sex education are important factors that influence the level of children's family sex education.

OBJECTIVETo assess the value of fluorescence in situ hybridization (FISH) combined with chromosomal analysis for the detection of Robertsonian translocation type trisomy 21 in amniotic fluid cells.

METHODSAmniotic fluid samples from pregnant women requesting prenatal diagnosis were cultivated. Metaphase cells were prepared for G-banding karyotype analysis. For the 5 Robertsonian translocation type trisomy 21, interphase nuclei from amniotic fluid and parental peripheral blood cells were prepared for FISH analysis.

RESULTSIn 2 cases, analysis of parental peripheral blood cells showed normal karyotypes. FISH analysis of amniotic fluid cells indicated that one sample had two copies of chromosome 21, which has a 46, XY, rob(21;21)(q10;q10) karyotype, whilst another had trisomy 21 by FISH, which has a 46, XY, rob(14;21)(q10;q10) karyotype. For the remaining three samples, analysis of parental peripheral blood cells indicated that their karyotypes were 45, XX, rob(14;21)(q10;q10), 45, XX, rob(15;21)(q10;q10) and 45, XX, rob(21;22)(q10;q10), whilst the karyotypes of amniotic fluid cells were 46, XX, rob(14;21)(q10;q10), 46, XY, rob(15;21)(q10;q10) and 46, XX, rob(21;22)(q10;q10), respectively.

CONCLUSIONCombined FISH and chromosomal analysis is an efficient method for detecting non-homologous Robertsonian translocation type trisomy 21. However, FISH has limited ability to detect homologous Robertsonian translocation type trisomy 21.

OBJECTIVETo observe whether adenosine Al receptor (Al R) mediated neuroprotection of Shenmai Injection (SI) on rat cerebral ischemia/reperfusion (I/R) injury.

METHODSThe focal cerebral I/R model was established by middle cerebral artery occlusion (MCAO). Totally 60 successfully modeled rats was divided into 5 groups according to randomized block principle, i.e., the model group, the SI group, the SI + AlR antagonist (1,3-dipropyl-8-cyclopentylxanthine, DPCPX) group, the AlR antagonist control group, and the dimethyl sulfoxide (DMSO) control group, 12 in each group. Besides, a sham-operation group was set up (n =12). SI at 15 mL/kg was peritoneally injected to mice in the SI group immediately after cerebral I/R. Equal volume of normal saline was injected to mice in the model group and the sham-operation group. DPCPX at 1 mg/mL was peritoneally injected to mice in the Al R antagonist control group 30 min before peritoneal injecting SI. DPCPX at 1 mg/kg and DMSO at 1 mL/kg were peritoneally injected to mice in the AlR antagonist control group and the DMSO control group 30 min immediately before cerebral I/R. Rats' neurobehavioral scores were assessed after 24 h reperfusion. The volume of cerebral infarction and Bcl-2 protein expression of cerebral infarction penumbra were also detected. Results Compared with the sham-operation group, neurobehavioral scores, the volume of cerebral infarction, and Bcl-2 protein expression increased (all P <0. 05). Compared with the model group, neurobehavioral scores and the volume of cerebral infarction obviously decreased, but Bcl-2 protein expression increased in the SI group (all P <0. 05). Compared with the SI group, neurobehavioral scores increased, the volume of cerebral infarction was obviously enlarged, and Bcl-2 protein expression was obviously reduced in the A1R antagonist control group (all P <0. 05).

CONCLUSIONSSI's neurobehavioral scores could be partially reversed in the Al R antagonist control group, the volume of cerebral infarction and Bcl-2 protein expression improved. AlR might possibly meditate neuroprotection of SI on MACO mire

Objective To analyze the therapeutic effect and prognosis according to a new CT classification of traumatic posterior occipital epidural hematomas (POEH). Methods We classified the CT presentation of 104 patients with POEH by sinus transverses: type Ⅰ hematomas were defined as up-sinus transverses; type Ⅱ hematomas were defined as sub-sinus transverses and type Ⅲ hematomas were defined as straddling sinus transverses. The above types were divided into unilateral or bilateral subtypes. Bone flap craniotomy through a median posterior approach was performed in patients with unilateral hematoma adjacent to the midline. Bone flap craniotomy through a median suboccipital approach was adopted for patients with bilateral middle occipital hematoma. Results Type Ⅰ enjoyed mild symptoms, good curative effect and low mortality rate (7%). Type Ⅱ and Ⅲ had serious symptoms and high mortality rate (13.3%, 16.6%, respectively). Conclusion The classification of the CT presentation of POEH is helpful in confirming the diagnosis, drawing up the scheme of treatment and judging the prognosis.

OBJECTIVETo observe the effect of acupuncture on the expression of extracellular signal-regulated protein kinases 1/2 (ERK1/2) in the subcutaneous fascia of SD rats.

METHODSEighteen SD rats were randomly divided into 6 groups (n=3) including 5 acupuncture groups and a control group. The rats in the 5 acupuncture groups received electro-acupuncture therapy in the regions of the inguinal groove, and at 0, 1, 6, 12, and 36 h after the last therapy, the superfacial fascia surrounding the acupuncture point (about 1.5 cm in diameter) were collected. The fascia tissues at the corresponding sites and at the acupoint Zusanli (ST36) were obtained from the control rats. The expression of ERK1/2 and phosphorylated ERK1/2 (p-ERK1/2) in the tissues were detected by Western blotting.

RESULTSERK1/2 and p-ERK1/2 expressions were detected in the tissues harvested from both the acupoint and the non-acupoint in the control rats with similar expression intensities. In the rats of each acupuncture group, ERK1/2 expression was significantly increased on the acupuncture side in comparison with the control side.

CONCLUSIONThe normal loose connective tissue may participate in tissue proliferation and differentiation possibly via phosphorylation of ERK. Acupuncture can promote the signal transduction pathway of ERK, which can be a possible mechanism for the effect of acupuncture in modulating the physiopathological conditions.
