In this study, the variation of pharmacokinetics behavior of raltitrexed (RTX) in rats after repeatedly injected with Huangqi injection was investigated. Twelve SD rats were divided into two groups: the multidose group and the RTX group. Rats in multidose group were iv. injected with Huangqi injection (dose of 1.575 mL x kg(-1)) everyday at 8 am for a week, and had free accesses for food and water. The rats were fasted for food but not water since 8 h before the eighth day. At the eighth morning, firstly, rats were injected with Huangqi injection (dose of 1.575 mL x kg(-1)), and 5 min later, were injected with RTX (dose of 0.467 mg x kg(-1)); rats in RTX group were not disposed in the previous seven days, also had free accesses for food and water, and were iv. injected with raltitrexed at the same time as Multidose group at the eighth day morning. Rat plasma was collected at different time and processed with methanol to precipitate the protein before HPLC assays. The pharmacokinetics parameters for two groups were calculated by software 3P97. Through the observation of drug concentration in plasma and time curve, we found that at almost every time point the concentration of RTX in plasma in multidose group was lower than the RTX group. When comparing the pharmacokinetics parameters between the multidose group and the RTX group, the average of AUC(0-t) and half-life(t1/2) of multidose group were decreased from 56 080 microg x min x L(-1) and 15.07 min to 35 834 microg x min x L(-1) and 8.95 min, respectively, while the clearance (CL) was increased from 0.51 to 0.83 mL x h(-1). Therefore, it could be deduced that repeatedly injected with AR injection may influence the renal excretion and glycometabolism of RTX, thus change pharmacokinetics behavior of raltitrexed in rats plasma. This result may give us a hint to prudantly manage the drug combination of RTX and Huangqi injection.

Objective:To investigate the prevalence and influencing factors of amnestic mild cognitive impairment of rural elderly in Guizhou province, which aims to provide scientific basis for the prevention and control of cognitive impairment in the elderly.Methods:Adopting a multi-stage cluster sampling method, a total of 1 535 rural Han and Bouyei elderly people aged 60 and above were selected from Guiyang city and Qiannan prefecture in Guizhou province as the survey subjects for the current situation survey, including demographic sociological characteristics, such as social was utilized behavior, social behavior disease history, height and weight and so on.Mini-mental state examination was utilized to measure cognitive function and SPSS 26.0 statistical software was used to perform χ 2 inspection and multivariate unconditional Logistics regression analysis to calculate odds ratio ( OR) and 95% confidence interval (95% CI). Results:A total of 242 elderly patients with aMCI were detected (15.8%). The results of univariate analysis showed that ethnicity(χ 2=4.333, P<0.05), gender(χ 2=18.367, P<0.01), marital status(χ 2=9.721, P<0.01), occupation(χ 2=7.786, P<0.01), annual family income(χ 2=28.085, P<0.01), current smoking(χ 2=11.873, P<0.01), specific hobbies(χ 2=25.968, P<0.01), physical exercise(χ 2=11.871, P<0.01), living style(χ 2=13.190, P<0.01), and activity participation(χ 2=13.004, P<0.01) all had an impact on aMCI. Multivariate Logistic regression analysis showed that Bouyei nationality( P<0.05, β=0.288, OR=1.333, 95% CI=1.002-1.775) and the women( P<0.05, β=0.516, OR=1.676, 95% CI=1.233-2.278)were risk factors for aMCI, and high annual family income( P<0.05, β=-0.839, OR=0.432, 95% CI=0.308-0.606), specific hobbies( P<0.05, β=-0.580, OR=0.560, 95% CI= 0.394-0.795), physical exercise( P<0.05, β=-0.410, OR=0.664, 95% CI=0.493-0.894), participation in activities( P<0.05, β=-0.424, OR=0.654, 95% CI=0.488-0.877), and non-living alone( P<0.05, β=-0.563, OR=0.569, 95% CI= 0.374-0.866) were the protective factors.Comparison of the prevalence of the disease between the Han and Bouyei nationalities, the detection rate of aMCI for the Bouyei elderly (18.0%) was higher than that of the Han (14.1%) (χ 2=4.333, P<0.05). After stratification according to gender, family annual income, specific hobbies, physical exercise, participation in activities and living style, the detection rate of elderly female subjects of Bouyei nationality was higher than that of Han nationality, whose difference was statistically significant (χ 2=5.562, P<0.05). The detection rate of Bouyei elderly was higher than that of Han when the annual household income was less than 30 000, and the difference was statistically significant (χ 2=8.570, P<0.01). Conclusion:The incidence of aMCI among the elderly of Bouyei nationality is higher, and the incidence of aMCI among females is higher than that of males, which should be paid more attention to.It is of vital importance to strengthen health education and publicity, guide the formation of knowledge-belief-behavior health-related behavior patterns, so as to improve the quality of life and reduce the risk of cognitive impairment.

Objective To review the effect of exposed and buried Kirschner wire fixation of lateral humeral condyle fracture in children.Methods Randomized control trials (RCTs) about exposed versus buried Kirschner wire fixation of lateral humeral condyle fracture in children were identified through electronic search using the Cochrane Collaboration search strategies and manual search.Electronic database included Cochrane Library,Medline,PubMed,CBM,VIP,CNKI,Wanfang database and other Chinese and English database.Manual research included related journals and conference proceedings.Quality analysis of the included literatures was performed using the methodological index for non-randomized studies (MINORS).RevMan 5.3 software was used for Meta analysis.Results Four studies involving exposed Kirschner in 150 cases and buried Kirschner in 351 cases were included.The two techniques were similar with respect to postoperative infection (OR =1.10,95％ CI 0.52 ～ 2.33,P ＞ 0.05),superficial infection (OR =1.45,95 ％ CI 0.66 ～ 3.18,P ＞ 0.05),reoperation rate (OR =2.29,95％CI 0.51 ～ 10.25,P ＞0.05),delayed union rate (OR =1.57,95％ CI 0.76 ～ 3.21,P ＞0.05) and total complications (OR =1.57,95％ CI 0.76 ～ 3.21,P ＞ 0.05).However,Kirschner wire exposure shortened the time of pulling out Kirschner wire (MD =-13.28,95％ CI-16.42 ～-10.14,P ＜0.05).Conclusion Applied for lateral humeral condyle fracture in children,exposed versus buried Kirschner wire fixation results in short Kirschner wire stabilization time that avoids local anesthetic and cost while pulling out Kirschner wire in the late stage.

BACKGROUND: In recent years, with the progress of shock therapy as well as the establishment and promoted application of arterial bypass grafting, thrombolytic therapy, percutaneous transluminal coronary angioplasty, extracorporeal circulation on cardiac surgery, cardiopulmonary resuscitation, limb replantation, and organ transplantation, blood reperfusion in multiple organs after ischemia has been achieved. However, the organs which undergo a period of ischemia appear to have the performance of damage aggravation.OBJECTIVE: To summarize the research progress of MG53 protein in protecting five organs from ischemia/reperfusion injury, thereby providing reference for further in-depth study.METHODS: A computer-based online search of PubMed, Duxiu Knowledge Search and CNKI databases was performed for relevant literatures puldished between 1986 and 2016. The key words were MG53, TRIM, Mitsugumin53, ischemic, reperfusion, preconditioning, postconditioning, RISK, membrane damage, Connexin43, KChIP2 in English and MG53, ischemia/reperfusion in Chinese. Finally 61 eligible articles were reviewed in accordance with the inclusion and exclusion criteria. RESULTS AND CONCLUSION: As a muscle-specific TRIM family protein, endogenous MG53 is involved in the repair of muscle cytomembrane damage, and the protective effects of ischemic preconditioning and postconditioning. Exogenous recombinant human MG 53 protein not only repairs membrane damage of various muscles and non-muscle cells, but also protects the myocardium, skeletal muscle, brain, lung and kidney from ischemia/reperfusion injury.

OBJECTIVE: To observe the effect of sevoflurane on the induction and maintenance of anaesthesia in children, and to evaluate its safety and effectiveness. METHODS: Forty child patients who conformed to the selection standard were operated under anaesthesia with intubation.Without premedicant, all the patients inhaled 100% oxygen(1L/min) and sevoflurane by mask, and escalated the concentration of sevoflurane (to the maximum concentration 7%) until the lash reflex disappeared, and the maintenance concentration was controlled under 4%. All the patients were intubated, together with vecuronium 0.1mg/kg. RESULTS: With little tract excretion, the achievement ratio of induction by sevoflurane was 100%, and the children tolerated well. With stable hemodynajmics,1% approximately 4.0% maintenance concentration of sevoflurane during the operation showed effective anaesthesia, no decreased heart rate or blood pressure appeared, and all the patients' body temperature was normal. CONCLUSION Sevoflurane for children induction can bring fewer stimuli in the respiratory tract,less cardiac vascular inhibition and palinesthesia time. Anaesthesia in children induced by sevoflurane is safe and effective.

BACKGROUND: Umbilical cord mesenchymal stem cells (UC-MSCs) are a group of cells that have self-renewal, highly proliferative and multidrug differentiation potential. The properties of UC-MSCs and their tumor tropism make them an ideal tool for glioma cell therapy. These cells can act by paracrine or as a delivery system for genes and drugs. It has been demonstrated that UC-MSCs can inhibit the growth of glioma and improve the survival after transplantation into the brain. OBJECTIVE: To summarize the molecular mechanisms and safety of UC-MSCs in the treatment of glioma and to provide a useful reference for further research. METHODS: We searched the PubMed and CNKI databases from 2000 to 2017 with the English terms of "glioma; umbilical cord mesenchymal stem cells" and the Chinese terms of "glioma; umbilical cord mesenchymal stem cells; safety; molecular mechanism". Based on the inclusion and exclusion criteria, 55 articles were finally reserved for review. RESULTS AND CONCLUSION: UC-MSCs have obvious effect on treating glioma. These cells can treat glioma through homing mechanism and paracrine mechanism as gene carrier and co-culture. Moreover, UC-MSCs have certain safety in the treatment of glioma.

We hereby reported a fetus with abnormal head shape, ventricular septal defect, gallbladder enlargement, low-set ears and local umbilical cord glial edema at 22 and 25 weeks of gestation ultrasound scan. A 15.318 Mb heterozygous microdeletion on chromosome 1p32.1p31.1, arr[GRCh37]1p32.1p31.1(61,279,239-76,597,189)×1, was indentified by chromosomal microarray analysis. The chromosome karyotype of the fetus was 46,XY,del(1)(p32.1p31.1). Therefore, this case was diagnosed as 1p32p31 microdeletion syndrome and proved to be a de novo variation based on routine G-banding analysis and chromosomal microarray analysis of the normal parents. This syndrome might present with abnormalities in the head shape, kidney, bladder and central nervous system. The couple decided to terminate the pregnancy after genetic counseling concerning the possible poor outcomes of the fetus.

OBJECTIVETo evaluate the vascularized (deep circumflex iliac vessels) iliac crest graft with internal oblique muscle as a method for reconstruction of composite mandibular defect.

METHODSVascularized iliac crest graft with internal oblique muscle was used to reconstruct the composite mandibular defects in 10 patients. All clinical data were analyzed retrospectively. A detailed inspection of the case-notes was undertaken to ascertain the presenting diagnosis, the surgery, the complications and the outcome. The type of mandibular defect was recorded.

RESULTSOf the 10 patients with composite mandibular defects including mandibular body, mandibular angle, mandibular ramus and the soft tissue around them, 7 patients were recorded with the defects of mandibular condyles. During the follow-up period from 3 months to 24 months, primary wound healing was observed in all patients, except one patient with minor muscular necrosis. All patients were satisfied with their facial contour and mandibular shape, without tumor recurrence. Donor site problems important enough to be recorded in the notes were minimal.

CONCLUSIONSThe vascularized iliac crest graft with internal oblique muscle offers a useful solution for reconstruction of composite mandibular defect. There is sufficient height and depth of bone to maintain a facial contour and mandibular shape. It can be used as a routine surgical technique to reconstruct composite mandibular defect.
