In clinical practice, muscular atrophy is a common sign in children. Because of relatively thick subcutaneous fat in children, muscular atrophy is not easy to be discovered. In order to confirm the diagnosis earlier, it is very important to take history in detail, to observe the motor function, cry, the posture of sitting and standing carefully, to do the physical examination thoroughly, and to use the assistant test reasonably.

Objective To observe the clinical effects of pemetrexed chemotherapy combined with radiotherapy in brain metastases of lung adenocarcinoma patients.Methods The data of lung adenocarcinoma patients with brain metastases were conducted retrospectively diagnostic analysis,and they were stratified randomized divided into the observation group (26 cases) and the control group (25 cases).The observation group was treated with pemetrexed chemotherapy combined with radiotherapy; the control group was treated with radiotherapy alone.Brain metastases,quality of life,short-term efficacy,adverse reactions,and patients' survival period were observed.Results The efficacy and quality of life of patients in the observation group were improved significantly than those of the control group,and adverse reactions were mild,the survival period was not significant between two groups.Conclusions Pemetrexed in combination with radiation therapy for the treatment of brain metastases from lung adenocarcinoma can effectively improve the short-term efficacy and quality of life of patients,and the adverse reactions are mild,it possess great application value in the treatment of brain metastases of lung adenocarcinoma.

Objective:To study p16 methylation of BEP-2D cells during its malignant transformation.Methods:Normal BEP-2D cells and BEP-2D cells treated by cigarette smoke condensate(CSC) for 15 weeks(W-15),25 weeks(W-25),38 weeks(W-38) and 43 weeks(W-43)respectively were chosen to study the p16 methylation status by Nested methylation specific PCR (Nested-MSP).Results:The p16 methylation was found in W-15,W-25,W-38 and W-43 BEP-2D cells,but not in the normal BEP-2D cell.Conclusion:The p16 methylation may be considered as a kind of biology-marker of the early diagnosis of lung cancer because the p16 methylation occurs in the earlier period of lung cancer.

0.05);There are significant differences between treatment group and control group in moderate and severe patients(P

Objective:To study the phamacokinetics of Nalmefene hydrochloride. Methods:30 healthy Chinese volunteers were assigned to 3 groups according to randomized design, and each group were given respectively a single intravenous administration dose of 0.5 mg, 1mg and 2mg of Nalmefene hydrochloride. The electrospray ionization positive selected reaction monitoring detections for Nalmefene hydrochloride and allyln-oroxymorphone (the internal standard) in the plasma and in the urine were used. The pharmaceutical parameters were calculated by 3P87 software. Results: The limit of the detection for Nalmefene hydrochloride was 0.0008 ng/ml in plasma and 0.0003 ng/ml in urine. There were good linear relationship range from 0.04 to 625ng/ml in plasma and 0.2 to 625 ng/ml in the urine. The variation coefficient in day and days, and the recoveries fitted the clinical pharmacokinetic study requirements. After a single intravenous administration of 0.5 mg,1mg, and 2mg of Na-lmefene hydrochloride, the obtained pharmacokinetic parameters were respectively as follows:Cmax were(1.74?0.48)?g/L,(4.17?1.08) ?g/L,(7.88?2.89) ?g/L;t1/2? were(12.83?3.98) h,(12.6?6.4) h, (10.58?3.74) h;V were (3.45?0.16) L/kg;(4.11?0.0716)L/kg、(4.25?0.56)L/kg;CL were (0.81?0.11) L/(h?kg), (0.85?0.15)L/(h?kg), (0.87?0.11) L/(h?kg);AUC0-∞ were (21.62?9.34) (ng/L)*h,(24.89?8.52) (ng/L)*h, (35?11.2) ng/L)*h;the urine accumulatived exc-retory rate were (78?21)%,(71?29)%,(78?19)%. Conclusion: The determination method for Nalmefene hydro-chloride in the plasma and in the urine by the electrosprayionization positive selected reaction monitoring detections is exclusive, accurate, sensitive and suitable. Pharmacokinetic characteristics in 3 groups of human treated with intravenous administration were described by a two-compartment model. The pharmaceutical characteristics of doxycycline hydrochloride in human body were linear in the range of 0.5~2.0 mg.

To confirm a patient's muscular dystrophy is a motor neuron amyotrophy or not,we should take history in detail,physical examination completely,and assistant test reasonably.The history include the first onset symptom such as dysarthrosis,dysphagia,weakness and muscular dystrophy in the hand.We should pay attention to the fasciculation,insensibility,sphincter problem,the symptom progress,and family history.The lab tests include serum creating kinas,electromyogram,muscle biopsy,and gene(SOD1,SMA)analysis.It is important distinguish motor neuron amyotrophy from other muscular dystrophy with the cause of the spinal anterior horn cells damage clear.

Objective To compare the effect of epidural anesthesia on vaginal total hysterectomy.Methods Eighty patients with vaginal total hysterectomy were selected and randomly divided into group Ⅰ(40 cases)and groupⅡ(40 cases).The patients of group Ⅰ were punctured with two-point method to the first tube of epidural in L1-2 and to the tail tube in L3-4 The patients of group Ⅱwere punctured with one-point method to the first tube of epidural in L2-3.Observed the level of anesthesia,induction period and anesthetic effect of all patients.Results The upper bound level of anesthesia was higher in group Ⅰthan that in group Ⅱ(P＜0.05),the induction period Wag shorter in group Ⅰthan that in groupⅡ(P＜0.05).The anesthetic effect Wag better in group Ⅰ(92.5%,37/40)than that in group Ⅱ(70.0%,28/40)(P＜0.05).There were significant difference in maintain time,dose of boost and total between group Ⅰand groupⅡ(P＜0.05).Conclusion Two-point method of epidural anesthesia is better for vaginal total hysterectomy,as it can provide rapidly and completely anesthetic effects.

Objective To make the clinical evaluation of Targis/Vectris restorations. Methods 337 cases with Targis/Vectris restorations were rechecked 12～50 months after cementation respectively. The restorations were evaluated clinically according to the USPHS standard. Results The changes of Targis/Vectris restorations in colour match, boundary line, wear and tear, marginal adaptation and surface grain were not obvious within 12～50 months. The secondary caries were not found. The successful rate of the restorations was 95.4 %.Conclusion The clinical prosthetic results of Targis/Vectris restorations are reliable.

Objective To observe the injuries of sodium citrate plasma(scP) on the growth and function of HepG2 cells.Methods The HepG2 cells were cultured.The viability,cell cycle and apoptosis,the leakage of LDH,total protein,glutathione and the changes on morphology of hepatocytes exposured to scP were investigated.Results The viability of HepG2 cells was inhibited when the cells were cultured in scP for 24h(F=37.108,P=0.001).After 48h,nearly all cells died except cells in 10% scP group.After the cells were exposed to scP for 24h,the percentage of S phase of the cell cycle and the rate of apoptosis were significantly increased compared to those of the control.The leakages of LDH were increased in the HepG2 following exposure to scP for 5h(P

Retinoblastoma 94(RB94)gene,a new tumor suppressor gene,is found in the past several years.It has been found that Rb94 gene has a more powerful antitumor effection compared with Rb110gene.After transfection,Rb94 gene could adjust telomerase activation,induce apoptosis and regulate cell cycle.It also has a synergistic action associated with radiotherapy or chemotherapy.
