Objective:To compare the difference of serum levels of M-phospholipaseA2 receptor ( PLA2R) antibodies in patients with idiopathic membranous nephropathy(IMN) detected by two different methods and evaluate the diagnostic value of two methods. Methods:Patients diagnosed as membranous nephropathy and other diseases with biopsy-proven from december 2014 to october 2015 in Shengjing Hospital of China Medical University were enrolled and devided into IMN group and non-IMN group. The serum levels of anti-PLA2R antibody were detected by both indirect immunofluorescence assay(IFA) and enzyme linked immunosorbent assay(ELISA). Results:The sensitivity of IFA and ELISA in IMN were 71. 3% and 68. 5%,and the specificities of two methods were the same as 100%. The area under ROC curves of anti-PLA2R antibody for IMN diagnosis were 0. 860 and 0. 839. The diagnostic value of IFA and ELISA was no statistically significant differences in IMN ( P>0. 05 ) , and the consistency of two methods was better (κ=0. 876). The IMN patients of positive anti-PLA2R antibody be susceptible to the low level of serum albumin (P<0. 05). The higher levels of PLA2R antibody were linked with the worse hypoproteinemia and the higher rate of nephrotic-range proteinuria in IMN patients. Conclusion:Two methods of detecting sera PLA2R antibody have higher sensitivity and specificity,so the sera anti-PLA2R antibody was a better biomarker in the diagnosis of idiopathic membranous nephropathy.

In this paper the species of ethnic medicinal plants Orobanche, Cistanche and Boschniakia, and their ethnopharmaceutical uses were comprehensively summarized by field investigation, systematical data analysis and comparison of relevant specimen and references. The results showed that six plants belonging to Orobanche were used as seven kinds of ethnic medicinal plants, two plants attributing Boschniakia were used as ten kinds of ethnic medicinal plants, two plants of Cistanche were used as three ethnic medicinal plants. The same plant was often used as different ethnic medicine in varied ethnic minorities. The effects of the ethnic medicines included yang-tonifying, hemostasis and analgesic activities. Hence, it is necessary to develop the rich plant resource of Orobanche for alleviation of Cistanche resources shortage.

OBJECTIVETo explore the rhythm regulatory mechanism of interleukin-6 (IL-6) in the process of moxibustion for rheumatoid arthritis (RA).

METHODSA total of 144 Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group, a moxibustion group, a sham operation group, an operation group, an operation+moxibustion group, 24 rats in each one. Each group was divided into 4 time points (0:00 am, 6:00' am, 12:00 am, 6:00 pm), 6 rats in each time point. The Light-Dark 12 : 12 was given in all rats for light-dark cycle. Except the blank group, rats in the remaining groups were treated with intracutaneous injection of freund's complete adjuvant at right-side foot to establish the model of RA. After the model establishment, bilateral adrenal, glands were removed in the operation group and operation + moxibustion group, while those in the sham operation group were not removed with identical operation procedure. Rats in the moxibustion group and operation + moxibustion group were treated with grain-sized moxibustion from 7:00 am to 9:00 am at "Shenshu" (BL 23) and "Zusanli" (ST 36) once everyday, 6 times were taken as one session and 3 sessions were required tatclly, while rats in the remaining groups received identical fixation without moxibustion. The general health state and foot volume of rats were measured before model establishment, after establishment and after treatment. After treatment, rats were sacrificed at each time point to collect the blood sample and measure the content of IL-6 by using enzymne-immunoassay method.

RESULTSCompared with the blank group, the foot swelling in the model group was obviously increased (P<0. 05); the IL-6 maintained circadian rhythm (P<0. 05), but the peak phase had a backward trend, famplitude had an increased trend and the median was significantly lifted (P<0. 05). Compared with model group, !the foot swelling in the moxibustion group was obviously decreased (P<0. 05); the IL-6 maintained circadian. rhythm (P<0. 05), and the peak phase had a forward trend, amplitude had a decreased trend and the median was significantly reduced (P<0. 05). Compared with the moxibustion group, the foot swelling in the operation--moxibustion group was obviously increased (P < 0.05); the IL-6 maintained circadian rhythm (P < 0.5), but the peak phase moved forwrd, and the median was significantly elevated (P < 0.05).

CONCLUSIONThe IL-6 in plasma maintains significant pathological circadian rhythm in RA rats; with the complete hypothalamic-pituitary-adrenal axis, moxibustion is likely to regulate the circadian rhythm of IL-6 to play an important role of anti-inflammatory effect in RA rats.

ObjectiveTo investigate the cause,diagnosis and treatment measures of neonatal pneumothorax.MethodsThe clinical data of 98 cases with neonatal pneumothorax in our hospital from Mar 2005 to Mar 2010 were reviewed retrospectively.ResultsThere were 27 premature neonates and 71 full-term neonates in the 98 cases.Ten cases were spontaneous pneumothorax and 88 cases were non spontaneous pneumothorax.After the treatnent of primary disease,pleural aspiration,chest drainage and mechanical ventilation,88 cases were cured,8 cases were improved and 2 cases died.ConclusionNeonatal pneumothorax is related with cesarean section,improper use of endotracheal intubation,meconium aspiration,premature hyaline membrane disease using pulmonary surfactant and ventilator therapy.Most pneumothorax is due to lung disease.The prevention of preterm birth and asphyxia can reduce the incidence of neonatal pneumothorax.

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.

Objective To explore the clinical effect of detection of serum procalcitonin (PCT), C-reactive protein (CRP)and white blood cell (wBC)on diagnosis and treatment of severe pneumonia in children.Methods A total of 189 cases of pediatric patients with pneumonia including 51 severe pneumonia cases (severe pneumonia group)and 138 common pneumonia cases (common pneumonia group)treated from Mar 2014 to Dec 2014 and 30 healthy cases (control group)were enrolled,and the level of PCT,CRP and wBC of all cases were detected.Results The levels of PCT before treatment in severe pneumonia group,common pneumonia group,and control group were 1.12(0.44 ~3.07)ng /ml,0.14 (0.09 ~0.26) ng /ml and 0.03(0.01 ~0.06)ng /ml respectively,and there were significant differences among three groups (P ﹤0.05,respectively).The levels of CRP before treatment in severe pneumonia group,common pneumonia group,and control group were 82.2(25.9 ~120.3 )mg /L,10.8 (5.3 ~23.9)mg /L and 3.2 (2.1 ~6.9) mg /L respectively,and there were significant differences among three groups (P ﹤0.05,respectively).The counts of wBC before treatment in severe pneumonia group,common pneumonia group,and control group were 10.1 (9.1 ~14.1 )×109 /L,8.8(6.8 ~1 1.7)×109 /L and 6.2(4.8 ~7.9)×109 /L respectively,and there was significant difference only between severe pneumonia group and control group (P ﹤0.05 ).The level of PCT and CRP significantly decreased in severe pneumonia group after one week of treatment[PCT:0.15(0.09 ~0.24)ng /ml,CRP:9.9(3.6 ~19.0)mg /L](P ﹤0.05),but there was no significant differ-ence of wBC counts in severe pneumonia group between after and before treatment[8.5(6.3 ~9.8)×109 /L vs.10.1 (9.1 ~14.1 )×109 /L](t =1.312,P =0.205 ).After two days of anti-inflammatory treatment in severe pneumonia group,serum PCT dropped to 44% of the level before treatment,and smoothly dropped to nearly 10% of the basic value every two days.Serum PCT was correlated with serum CRP in children with pneumonia(R2 =0.550 4,P ﹤0.05).Conclusion The combined detection of PCT and CRP could provide important guidance for the differential diagnosis,treatment and prognosis for severe pneumonia in children.

Objective To construct the vector that expresses the fusion protein of HIV-Tat protein and red fluorescent protein(mCherry) in mammalian cells,and observe by fluorescence microscopy the intracellular transduction and localization of recombinant protein in cells,in order to obtain a useful tool for the study of the uptake mechanism and intracellular localization of HIV-TAT.Methods With the designed primer coding mCherry sequence,the mCherry gene was amplified by PCR with the vector pmCherry-C2 as template,and inserted into vector pET14b-His-TAT to construct the expression vector pET14b-His-TAT-mCherry.The constructed vector was then transformed into E.coli BL21(DE3),which had been identified by PCR and double digested with restriction endonuclease,followed by sequencing.After IPTG induction,the recombinant protein of His-TAT-mCherry was lyzed and analyzed with SDS-PAGE.Purified His-TAT-mCherry recombinant protein was added to Hela cells and the fluorescence was observed to evaluate the transduction efficiency.Results The results of identification by PCR,digestion with restriction endonuclease and sequencing indicated that the vector His-TAT-mCherry was correctly constructed.His-TAT-mCherry fusion protein was expressed in mammalian Hela cell line and purified successfully,and the fusion protein showed cellular transduction activity.It was found by fluorescence microscopy that the red fluorescence protein located mainly over the cytoplasm,and also the membrane to some extent.Conclusion The expression vector is successfully constructed for HIV-TAT labeled with mCherry sequence.Effective expression and purification of this fusion protein is achieved.It has been observed that the constructed vector may be expressed in mammalian Hela cell under active condition.Thus,it might be useful in the study of uptake mechanism and intracellular localization of HIV-TAT.

Objective To investigate the effect of stellate ganglion block ~SGB) on formalin-induced nociceptive behavior of rabbits, the expression of brain-derived neurotrophic factor ~BDNF) of dorsal root ganglia ~DRG) and the concentration of serum interleukin-8 ~IL-8) in rabbits. Methods Twenty-four rabbits were used in this study. Catheters were inserted closely to right stellate ganglia of the animals, which were randomly divided into control group ~A), SGB group ~B) and pain model group ~C). Group B and C were administered with an injection of 0.5ml of 3% formalin into the right front paw subcutaneously, group A 0.5ml saline by the same way. 0.5ml of (0.25)% bupivacaine was administered via the catheter in group B at 10 minutes before injection, while group A and C were given 0.5ml of saline at the same time. Nociceptive behavior was observed for 60 minutes after injection, and assessed by weighted pain score. Serum IL-8 was measured radioimmunologically at 10 minutes ~T_0) before injection, 10 ~T_1), 60 ~T_2) and 120 minutes ~T_3) after injection. The expression of BDNF in the right DRG of cervical 7, 8 and thoracic 1 was investigated immunohistochemically at 120 minutes after injection. Results Formalin-induced nociceptive behavior in phase Ⅱ was relieved following SGB. The concentration of serum IL-8 in groups B and C at T_2 and T_3 was significantly increased than that at T_0 and T_1~P
