Quinone is one of the electron transporters of the microbial respiratory chain. The dominant quinone of one species of bacteria is different from other bacteria. So the quinone profile of environmental samples can reflect the microbial community. This paper briefly introduces the analytical method used for microbial quinones. The microbial community in an activated sludge sample is studied using this method.

Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

Background and purpose:Checkpiont targeted immunotherapy in the field of solid tumor therapy has huge potential, triggering a boom in the study of immune targeted drugs. A study has provided a basis for the follow-up study of ipilimumab combined with chemotherapy in the treatment of non-small cell lung cancer(NSCLC) patients. This study counted the adverse event statistics that ipilimumab or placebo combined with paclitaxel and carboplatin as first-line therapy for the treatment of stage Ⅳ or recurrent squamous cell carcinoma to evaluate the safety of ipilimumab combined with chemotherapy in the treatment of advanced squamous cell carcinoma.Methods:This study selected 13 patients with ECOG scores≤1 and stage ⅣA or ⅣB squamous cell carcinoma in the Shanghai Chest Hospital, Shanghai Jiao Tong Uni-versity. Randomized controlled double blind trial was used in this study. The patients of experimental group were treated with ipilimumab combined with paclitaxel and carboplatin, while the patients of control group were treated with the placebo combined with paclitaxel and carboplatin. Adverse events (AEs) were counted in the process of treatment.Results:The most common AEs were the 1/2 grade AEs. Immune-related AEs (irAEs) reported in the ipilimumab group included level Ⅰ of diarrhea and pruritus, level Ⅱ of rash and pruritus and level Ⅲ of hypophysitis.Conclusion:The side effects of ipilimumab were mild, tolerable and manageable.

72 cases of treatments on insomnia were recorded in the medical books of Ming and Qing dynasties(A.D.1368～1911 years).The compatibility regularity of treating insomnia in these 72 cases were statistically analyzed with frequency and the R type cluster analysis methods. Combining the data and modern recognition, compatibility and medication regularity of treating insomnia was further analyzed.

This study aimed to explore the mechanism of volatile oil from purslane in treating itch induced by eczema through establishing the itch model,stimulating the keratinocyte with capsaicine (CAP).SD rats were divided into the control group,the model group,the high dose group of volatile oil from purslane,and low dose group of volatile oil from purslane.After finishing the experiment,the morphology of keratinocytes was observed by immunofluorescence technique,while Ca2+ concentration was detected by flow cytometry,and the contents of leukotriene A4 methyl ester (LTA4),interleukin-31 (IL-31) and hydroxy trptamine H1 (HTH1) were quantified by ELISA assay.The expression of TRPV1 mRNA in keratinocytes was tested by RT-PCR,while the protein level of TRPV1 was quantified by western blot.Compared with the model group,it was found that the cell count of positive keratinocytes,the Ca2+ concentration,the levels of LTA4,IL-31 and HTH1,and the mRNA and protein expressions of TRPV1 in the high dose and low dose groups were significantly decreased (P ＜ 0.05).In conclusion,it was demonstrated that the volatile oil from purslane may relieve itch through inhibiting the activation of TRPV1 and reducing secondary inflammatory reaction.

Objective To evaluate the right ventricular(RV)systolic function in patients with primary pulmonary hypertension(PPH)using real -time three -dimensional echocardiography(RT -3DE)and ultrasonic two-dimensional speckle tracking imaging(STI).Methods Patients with PPH were divided into three groups according to pulmonary arterial systolic pressure(PASP),consisted of mild group,moderate group and severe group,with 20 cases in each group.20 healthy cases were included as the control group.The global RV dysfunction,including RV end -diastolic volume(EDV),end -systolic volume(ESV),stroke volume(SV),ejection fraction(EF),tricuspid annular plane systolic excursion(TAPSE),longitudinal peak systolic strain(SL),longitudinal peak systolic strain rate(SRL), longitudinal peak systolic velocity(VL)in RV free wall and interventricular septum for basal,mid and apical segment were detected by using RT -3DE and STI.Results Global RV ESV increased in all groups(t =3.10,7.53,7.72,all P <0.01),but The RV EDV in the moderate and severe group was higher than that of normal and mild groups(t =4.02,5.82,3.04,5.15,all P <0.01),the RT SV and EF in all case groups was fewer than that of normal(t =-9.33 ~-2.71,all P <0.05).Linear correlation analysis showed negative correlation between EF and ESV,EDV (r =-0.776,-0.638,all P <0.01).The level of RV free wall peak systolic displacement of tricuspid annulus, ventricular septal annulus peak systolic displacement,tricuspid annulus peak systolic displacement midpoint and the right longitudinal ventricular shortening fraction were significantly lower than those of the control group(all P <0.01). Linear correlation analysis showed positive correlation between EF and TAPSE(r =0.761,0.593,0.745,0.773,all P <0.01).The VL and SL in RV free wall and interventricular septum for basal,mid and apical segment were fewer than the control group(P <0.05 or P <0.01),but SRL of RV for all segments showed no significantly different in all groups(P >0.05).Conclusion RT -3DE and STI technology can be useful in assessing RV function every period.

An analysis method has been established to test 27 elements (Li, Be, B, Mg, Al, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Sr, Mo, Cd, Sn, Sb, Ba, La, Hg, Pb, Bi) in Maca nationality's medicine with microwave digestion-ICP-MS. Sample solutions were analyzed by ICP-MS after microwave digestion, and the contents of elements were calculated according to their calibration curves, and internal standard method was adopted to reduce matrix effect and other interference effects. The experimental results showed that the linear relations of all the elements were very good; the correlation coefficient (r) was 0.9994-1.0000 (Hg was 0.9982) ; the limits of detection were 0.003-2.662 microg x L(-1); the relative standard deviations for all elements of reproducibility were lower than 5% (except the individual elements); the recovery rate were 78.5%-123.7% with RSD lower than 5% ( except the individual elements). The analytical results of standard material showed acceptable agreement with the certified values. This method was applicable to determinate the contents of multi-elements in Maca which had a high sensitivity, good specificity and good repeatability, and provide basis for the quality control of Maca.

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.

RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).

CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.
