Objective To investigate the thermal effects on tissue structures during microwave endometrial ablation(MEA)and seek a feasible method of endometrial thinning and a fitting mode of applicator radiating microwaves.Methods Operations were performed between the group of thorough uterine curettage and the group of early follicular phase in in vitro or in vivo uterus.The former was treated with MEA after thorough uterine curettage;while the latter was treated with MEA in the early follicular phase directly.The applicator radiating microwaves were moved in "Z" or "Z+W" shape inside uterine cavity.At the same time the serosal temperature was measured in the uterine fundus,tael cornua uteri,the posterior wall and the lower part of anterior wall.After operations the uterine specimens were stained by hematoxylin- eosin,and respiratory enzyme dehydronicotinamide adenine dinucleotide phosphate diaphorase(NADH-d) methods.The morphologic changes and the depth of tissue thermal damage were evaluated using an optical microscope and electron microscope.Results(1)Under the optical microscope the endometrial glands became distorted,the cell boundaries disappeared,the nucleoli turned condensed and were stained darker. A large number of acute inflammatory cells appeared in fibrous tissue.In the shallow muscle layer cells were arrayed thickly,nucleoli were solidified and condensed,and cellular plasm were concentrated.The endometrial and the superficial muscle layers were damaged and colorless with NADH-d staining.The scope of the tissue thermal damage was clearly seen.Under an electron microscope,some smooth muscle ceils, chromatin,karyotheca and cellular membranes were destroyed.The mitochondria were swollen,membranes were ruptured,and the crista disappeared.Many organelles were destroyed.The chromatin was lightly wrecked in the transitional area between putrescence and the normal smooth muscle tissue.Karyotheca and cellular plasm still existed,the mitochondria were highly edematous and the crista were disappeared,and the granular endoplasmic reticula were slightly expanded and degranulated.(2)The serosal temperature in in vitro uterus was significantly higher than that in in vivo uterus(P0.05).The injury depth of the "Z+ W" radiation group increased significantly than that of the " Z" radiation group(P

Objective To investigate the therapeutic effect and side effects of concurrent chemotherapy and intensity-modulated radiotherapy (IMRT) following induction chemotherapy (IC) in patients with locally advanced nasopharyngeal carcinoma (NPC).Methods From January 2005 to January 2009,62 cases of locally advanced NPC confirmed by pathological and cytological examination received IC with vinorelbine (25 mg/m2) plus cisplatin (25 mg/m2) for 2-4 cycles and then concurrent chemotherapy and IMRT.Conventional fractionated radiotherapy was adopted in IMRT.The radiotherapy for the nasopharyngeal region was performed a dose of 72-76 Gy/36-38 fractions,and additional 5-Gy gammaknife treatment was carried out in case of local tumor residue.Prophylactic irradiation to the cervical lymph nodes was performed at a dose of 50 Gy,and the dose was increased to 60-70 Gy in case of lymph node enlargement.Results The follow-up rate was 100％.The patients showed a response rate (RR) of 89％ in the nasopharyngeal region and an RR of 90％ in the cervical lymph nodes.The 1-,2-,and 3-year overall survival rates,disease-free survival rates,local relapse-free survival rates,and distant metastasis-free survival rates were 97％,92％,and 82％,94％,73％,and 65％,97％,89％,and 87％,and 97％,84％,and 77％,respectively.The incidence rates of grade 3-4 acute reactions were 37％ for leucopenia,18％ for thrombocytopenia,and 6％ for mucositis.No grade 3-4 long-term temporomandibular joint injury and xerostomia were observed.Conclusions Concurrent chemotherapy and IMRT following IC with vinorelbine (25 mg/m2) plus cisplatin (25 mg/m2) have tolerable adverse effects and can achieve high survival rate in the patients with locally advanced NPC.

OBJECTIVETo reveal the transmembrane signal pathway participating in regulating neuron functions of treating Alzheimer's disease (AD) by acupuncture.

METHODSSAMP8 mice was used for AD animal model. The effect of acupuncture method for qi benefiting, blood regulating, health supporting, and root strengthening on the amount and varieties of transmembrane signal proteins from hippocampal lipid rafts in SAMP8 mice was detected using HPLC MS/MS proteomics method.

RESULTSCompared with the control group, acupuncture increased 39 transmembrane signal proteins from hippocampal lipid rafts in SAMP8 mice, of them, 14 belonged to ionophorous protein, 8 to G protein, 8 to transmembrane signal receptor, and 9 to kinase protein. Totally 3 main cell signal pathways were involved, including G-protein-coupled receptors signal, enzyme linked receptor signal, and ion-channel mediated signal. Compared with the sham-acupuncture group, acupuncture resulted in significant increase of kinase signal protein amount. From the aspect of functions, they were dominant in regulating synapse functions relevant to cytoskeleton and secreting neurotransmitters.

CONCLUSIONThe cell biological mechanism for treating AD by acupuncture might be achieved by improving synapse functions and promoting the secretion of neurotransmitters through transmembrane signal transduction, thus improving cognitive function of AD patients.

Objective To investigate the correlation among expression of serum VEGF without operation between pre-and post-chemoradiotherapy in non-small cell lung cancer (NSCLC) patients, to explore the correlation of markers on prognosis and effect. Methods The serum vascular endothelial growth factor (VEGF) were detected in 50 patients without operation between pre-and post-chemoradiotherapy with NSCLC by ELISA method. The group t-test was played into before concurrent chemoradiotherapy and normal control. The paired t-test was played into before and after concurrent chemoradiotherapy. Results The prechemoradiotherapy serum VEGF ( 241.09 ± 52.45 ) ng/L in NSCLC patients was significantly higher than those in normal control patients (103.72 ± 39. 22) ng/L (t = 2. 50,P ＜0. 05 ). The pre-chemoradiotherapy serum VEGF in NSCLC patients was closely related to pTNM stage, distant metastasis, grade of cell differentiation and the size of the primary tumors ( t = 9. 61 - 14. 94, all P ＜ 0. 05 ), but not to the histological classification, type of the tumor, lymph node status, age, gender of the patients or smoking or not (t =0. 58 - 1.84, all P ＞ 0. 05 ). The pre-chemoradiotherapy serum VEGF ( 24 1.09 ± 52. 45 ) ng/L was significantly higher than that of the post-chemoradiotherapy ( 133.64 ± 33.62) ng/L ( t = 12. 20, P ＜ 0. 01 ). The post-chemoradiotherapy serum VEGF decreases to the pre-was the biggest in the CR patients (( 92.35 ± 37.48ng/L) ,t =3.79,P ＜0. 01 ) ,the smallest in the PA patients ( (276.32 ±47.98) ng/L,t = 1.32,P ＞0. 05) ) ,and bigger in the PR patients and the NC patientspatients ( ( 113.10 ± 39. 20) ng/L,t = 13.58,P ＜0. 01 and ( 198.10 ± 42.68 ) ng/L, t = 4. 78, P ＜ 0. 05 ) ), respectively. Conclusions Elevation of serum VEGF exists in patients with NSCLC . The serum VEGF in patients with NSCLC might be helpful to evaluate the biological behavior of lung cancer. Detection of VEGF expression maybe helpful for predicting the prognosis of NSCLC patients.
