Objective To observe the effect of Fujian Tablets(FT),a prescription with the actions of nourishing liver and kidney,on the expression of microtubule-associated protein 2(MAP-2) in cerebral infarction rats at different time points,and to explore its mechanism on promoting nerve cell differentiation.Methods A total of 240 male Sprague Dawley rats were divided into normal control group,sham-operation group,model group and FT group.Focal cerebral ischemia models were established by occlusion of the middle cerebral artery according to the reformed Longa method in rats,and were subdivided into 3-,7-,14-,28-,and 42-day cerebral infarction subgroups.FT group was given FT in the dose of 9 g?kg-1?d-1,and the other groups were given the same dose of distilled water.Results In the model group,MAP-2 expression in the hippocampus increased and reached a peak on day 3,which were notably different from that in the normal control group(P0.05).In FT group,MAP-2 expression increased on day 3,reached a peak on day 7,remained high level till day 14,and then decreased,the difference being significant compared with the model group(P

[ ABSTRACT] AIM:To investigate the changes of peroxisome proliferator-activated receptors ( PPAR)α/peroxi-some proliferator activated receptor coactivator 1 alpha ( PGC-1α) in doxorubicin ( DOX) induced dilated cardiomyopathy ( DCM) and its effect on the energy metabolism and myocardial function in mice .METHODS:Forty mice were randomly divided into 4 groups:control group, DOX group, PPARαinhibitor group and PPARαagonist group.The DCM model was established by injection of DOX.The protein levels of PPARα/PGC-1αwere detected.The PPARαinhibitor and PPARαagonist were used 2 weeks beforeinjection of DOX.The contents of adenine acid and phosphocreatine ( Pcr) in the mito-chondria were measured by high-performance liquid chromatography ( HPLC) .The ANT activity was analyzed by the atrac-tyloside-inhibitor stop technique.The changes of the echocardiography and hemodynamics were also observed.RESULTS:DOX induced DCM model was successfully established.The protein levels of PPARαand PGC-1αin control group were significantly higher than those in DOX group (P<0.05).Both of the high-energy phosphate contents and the transport ac-tivity of ANT were decreased in DOX group (P<0.05), and the hemodynamic parameters were disordered (P<0.01). Compared with DOX group, PPARαinhibitor pre-treatment significantly reduced the PPARα/PGC-1αexpression.Mean-while, high-energy phosphate contents in the mitochondria and the ANT transport activity of the mitochondria decreased, as well as the left ventricular function ( P<0.05) .On the other hand, PPARαagonist significantly increased the expression of PPARαand PGC-1α, and improved the transport activity of ANT.In addition, the hemodynamic parameters were amel-iorated, but the high-energy phosphate contents of the mitochondria did not significantly change.CONCLUSION:PPARα/PGC-1αplays an important role in the regulation of ANT transport activity in dilated cardiomyopathy induced by DOX, and the activation of PPARα/PGC-1αhas protective effects on the DCM induced by DOX.

Objective To evaluate free or pedicled perforator flaps for repairing chronic osteemylitis with soft-tissue defect in the distal lower extremity. Methods From May of 2006 to October of 2007, 28 consecutive patients of chronic osteomylitis with soft-tissue defect in the distal lower extremity underwent surgical debridement and reconstruction with free or pedicled perforator flaps. There were 13 free flaps. The free anterolateral thigh flaps were used in 2 cases to repair the soft defects in the front of leg, 3 cases in the front of the malleolus, 2 cases in the dorsum of foot, 2 cases in the heel. The free lateral crural flaps nourished by perone al artery were used in 4 cases to repair the soft defects in the dorsum of foot. There were 15 pedicled flaps. Posterior tibial artery perforator flaps were used in 4 cases to repair the soft defects in the front of leg, and 2 cases in the medial malleolus. Lateral retromalleolar perforator flaps nourished by peroneal artery were used in 6 cases to repair the soft-defects in the heel, 1 case in the lateral malleolus and 1 case in the dorsum of foot, the first dorsal metatarsal artery perforator flap was used to repair the proximal dorsum of hallux. The wound was closed with irrigation-suction in 7 cases and with vancomycin-impregnated gelatin in 8 cases. Results All 27 flaps were successfully survived except insuffcient vein refluence in 1 posterior tibial artery perforator flap, which resulted in a superficial necrosis and healed spontaneously. The follow-up period from 6 months to 2 years revealed that recurrence developed in two diffuse type patients and both were treated once and twice with success, respectively. The others healed without any signs of recurrences. No debulking procedure was necessary in any case. Secondary bone graft was performed in 3 cases. All patients were ambulatory and fully weight-bearing with normal clinical parameters at the time of last review. According to the evaluating criteria for the treatment of foot disease, the mean score was 84.5. Conclusion Free or pedicled perforator flap has been shown to be well vascularised, and it is feasible for the treatment of chronic osteomyelitis with soft-tissue defect in the distal lower extremity.

Methods 112 schizophrenic patients were divided into study group (56 cases) and control group (56 cases). Two groups were treated with antipsychotics. The control group was subjected to general healthy education, while the study group received education intervention of self-control. All patients of two groups were assessed by Self-care Behavior Questionnaire(SCBQ), Brief Psychiatric Rating Scale(BPRS) and Social Disability Screening Schedule(SDSS) before and affter intervention, and drug-compliance was also assessed.Results After one year, the total score of SCBQ was significantly higher in the study group than in the control group, while the total scores of BPRS and SDSS were significantly lower in the study group than in the control group (P<0.01); Drug-compliance was significantly more in the study group than in the control group(P<0.01).Conclusion Group education intervention of self-control can improve distinctly the ability of self-control disease, have positive effect on remission psychical symptom, and improve the social function and retention psychosomatic healthy.

Objective To analyze the operative therapeutic effect of proximal femoral nail antirotation blade (PFNA),dynamic hip screw (DHS) and femoral proximal locking compression plate (LCP)internal fixation in treatment with femoral intertrochanteric fracture of the aged.Methods Seventy-three aged patients with femoral intertrochanteric fracture were divided into 3 groups according to different internal fixation method:PFNA group (30 cases) was treated with PFNA internal fixation,DHS group (22 cases) was treated with DHS internal Fxation,LCP group (21 cases) was treated with LCP internal fixation.The operative time,intraoperative bleeding volume,fracture healing time,bad limb load time and hip joint function score were compared among the 3 groups.Results The operative time in PFNA group,DHS group and LCP group was (73.9 ± 8.5),(82.3 ± 10.6),(79.5 ± 11.2) min,there was statistical difference between PFNA group and DHS group (P ＜ 0.05),but there was no statistical difference between PFNA group and LCP group (P＞ 0.05).The intraoperative bleeding volume in PFNA group was significantly lower than that in DHS group and LCP group [(160.2 ± 15.6) ml vs.(208.4 ± 20.2) and (216.6 ml ± 24.9) ml],there was statistical difference (P ＜0.05).The fracture healing time and bad limb load time in PFNA group were significantly shorter than those in DHS group and LCP group [(97.4 ± 5.8) d vs.(101.2 ± 4.2),(110.0 ±8.3) d and (78.0 ±5.4) d vs.(85.9 ±7.6),(90.8±6.0) d],furtbermore DHS group were significantly shorter than those in LCP group,there were statistical differences among the 3 groups (P ＜ 0.05).There were no statistical differences in excellent and good rate of hip joint function score among the 3 groups (P ＞ 0.05).Conclusions PFNA is the ideal therapeutic method for femoral intertrochanteric fracture of the aged.It has better curative effect compared to the DHS and LCP,and has less surgical trauma and can shorten the recovery time.

This study aimed at developing an ultra-performance liquid chromatography electrospray time of flight-mass spectrometry (UPLC-ESI-QTOF-MS) method for the identification of bovine hide gelatine from the shell glue of the red-eared slider.Tortoise shell glue was made from the shell of red-eared slider or Reeves' turtle (Chinemys reevesii).The samples were analyzed on UPLC-ESI-QTOF-MS after being digested by trypsin,and the ions at m/z 604.8,m/z 641.3,m/z 790.8 of the marker peptides of bovine hide gelatin were detected.As a result,it was found that the test results of the ions made from the shell of red-eared slider at m/z 641.3 were positive,taking the same fragmentation regularity of MS/MS as the standard of bovine-hide gelatine,while negative results were detected from the ions made from the shell of Reeves' turtle.In conclusion,the method was simple and accurate provided a basis for distinguishing the tortoise shell glue from bovine hide,which could be also used for the quality control of tortoise shell glue.

Objective To investigate the relationship between maintaining concentration and loss of consciousness (LOC) concentration of propofol target controlled infusion (TCI) in patients undergoing heart valve replacement.Methods Thirty patients undergoing elective heart valve replacement were enrolled to receive propofol by ladder plasma TCI for anesthesia induction,8 males and 22 females.The initial plasma concentration (Cp) of propofol was set to 1.0 μg/ml,0.3 μg/ml Cp was increased every 1 min until LOC when the prediction effect-cite concentration (Ce) reached 0.5 μg/ml,then sufentanil 0.8-1.0 μg/kg and rocuronium 0.6-0.9 mg/kg were given for intubation.When BIS reached 50,Cp was decreased to the level of Ce.All the surgeries were performed under hypothermia CPB.MAP,HR,CVP,CO,SV,SVR,BIS,propofol Cp and Ce values were recorded at baseline (T0),LOC (T1),BIS reached 50 (T2),and other time points during operation (T3-T9).The correlation analysis between propofol Ce at LOC and perioperative variables were completed.Results In correlation analysis,there was a significant positive correlation between propofol Ce at LOC and baseline CO,SV (P<0.01),there was a significant negative correlation between propofol Ce at LOC and age (P<0.05),there was a significant positive correlation between propofol Ce at LOC and propofol Ce at T2-T9(P<0.01).Conclusion In patients undergoing valvular replacement,the Ce of propofol at maintenance are related to the concentration of propofol at LOC,which is helpful for adjusting the Ce of propofol at maintenance according to the Ce of propofol at LOC.

OBJECTIVETo study the status quo of oral professional and technical personnel of Guyuan city, Ningxia.

METHODSIn consultation with Administrative Department of Public Health, all oral health institutions by age, gender, education, professional, and department in four counties (Longde, Jingyuan, Pengyang and Xiji) and Yuanzhou district in Guyuan City were investigated. The distribution, basic information, professional branch, ratio with the amount of health system medical staff and population were analyzed.

RESULTSAll comprehensive hospital at the county level and above set up department of stomatology. Center for Disease Control and Prevention, health inspection bureau, maternity and child health care bureau and 78.46% town health center didn't set up department of stomatology. Oral professional and technical personnel of Guyuan city in number was 115 and mainly young doctors, men were more than women. On education, the tertiary education was mostly received. On professional title, number of middle and senior professional title was relatively small. On profession, multi-disciplinary was common. The ratio of oral professional to general medical staff were 1:30, to local population was 1:13 thousands.

CONCLUSIONThe education and professional title of oral professional and technical personnel should be improved. It is recommended that comprehensive hospitals above the county level should branch in Stomatology, Center for Disease Control and Prevention, health inspection bureau, maternity and child health care bureau and town health center should offer services of stomatology, at least provide one dental professional and technical personnel in each place.
