Results There were total 68 people in 5 generations, including 24 patients in 4 generations .Both male and female were suffered. All patientes of this kindred showed myotonia with onset the illness from the infant, and 16 cases accompanied with hypermyotrophy.The levels of creatases and dielectric in serum were normal in all the cases. Spontaneous myotonic electric potential were observed on electromyography( EMG ) in 2 cases.The proband was found in light microscope by biopsy that muscle fibers arranged loosenly , size of them mismatched , transverse striation was unclear and some of them was hyperplasia and hypertrophy. Muscle cells degenerated gently with a few inflammatory cells infiltration. No mutation was found in the whole 23 extrons of CLCN1 gene in the 3 patients.Conclusions This kindred accords with the autosomal dominant heredity form Thomsen's disease. The affected numbers have the typical clinical characteristics. No mutation is found when 23 extrons of CLCN1 gene screened in the patients which indicate the genetic heterogeneity may be exist in this kindred.

Objective To analyze the clinical effect of neoadjuvant chemotherapy( oxaliplatin combined with S-1) in the treatment of advanced gastric cancer,and to detect its influence on expressions of vascular endothelial growth factor(VEGF) and matrix metalloproteinase-2(MMP-2).Methods A total of 70 patients with advanced gastric cancer were randomly divided into research group ( n=35 ) and control group ( n=35 ) .The patients in the control group were given surgery treatment and general drug chemotherapy,while the patients in the research group were given the neoadjuvant chemotherapy on the basis of the control group.The incidence of cancer recurrence and the expressions of MMP-2,VEGF of the two groups were observed.Results In the research group,the expressions of MMP-2 or VEGF were significantly different before and after chemotherapy(χ2 =10.03,χ2 =9.11,all P<0.01). The 3-year survival rate in the research group(71.43%) was significantly higher than 45.71% in the control group,there was significant difference(χ2 =11.70,P<0.05).Conclusion Neoadjuvant chemotherapy can reduce the expressions of MMP-2 and VEGF in tumor tissues,indicates that it may play an important role in patients with advanced gastric cancer and can be used in clinic.

Objective To investigate the pharmacokinetics of propofol when combined with remifentanil in patients with liver cirrhosis.Methods Ten patients (5 males, 5 females) with liver cirrhosis scheduled for endoscopic esophageal varix ligation (test group) and 10 cases (5 males, 5 females) with normal liver function scheduled for gastroscopy (control group), aged 18-55 yr, weighing 40-75 kg, were studied. The patients were unpremedicated. All the patients received iv injection of propofol 1.5 mg/kg and remifentanil 0.5 μg/kg, and 5 min later propofol 0.5 mg/kg and remifentanil 0.2 μg/kg was given again. Blood samples were taken from radial artery before administration and at 2, 5, 10, 15, 20, 30, 45, 60, 80 and 120 min after administration for determination of the plasma propofol concentration using gas chromatography-mass spectrography. The pharmacokinetic parameters were calculated using DAS 2.0 software.Results The pharmacokinetics of propofol was best described by a three-compartment open model. There was no significant difference in the distribution half-life, elimination halflife , terminal half-life, area under the curve and transfer rate constant between the two groups ( P ＞ 0.05) . The apparent volume of distribution of propofol and clearance were significantly increased in test group compared with control group (P ＜0.01) .Conclusion When propofol combined with remifentanil is used in patients with liver cirrhosis, the apparent volume of distribution of propofol and clearance are significantly increased, while no changes in the other pharmacokinetic parameters are found.

Objective To compare the dosimetric difference of volumetric modulated arc therapy (VMAT) plans for the loco-regionally advanced nasopharyngeal carcinoma (NPC) patients using 6 MV X-ray flattening filter-free (FFF) and flattening filter (FF) modes.Methods Ten previously treated patients with loco-regionally advanced nasopharyngeal carcinoma were retrospectively included and replanned using FFF and FF VMAT,respectively.Meeting all clinical criteria,the dose-volume histograms (DVH),dose distribution of target volume and organs at risk (OARs),target conformity index (CI),total monitor unites (MUs) and treatment time were compared across the plans.Results VMAT plans suing either FFF and FF modes can meet the clinical objectives.The maximum and mean target dose of FFF VMAT plans were significantly higher than that of FF VMAT plans (t =-0.31,-O.35,P ＜ O.05).Yet the planning target volume (PTV) CI of FF mode was slightly better than of FFF mode (t =5.42,P ＜0.05).The maximum doses of lenses in FFF VMAT plans were lower than that of FF VMAT plans (t =25.87,17.45,P ＜ 0.05),and other OARs displayed no significant difference.The mean total MUs of FFF and FF VMAT plans were (699 ± 16) and (628 ± 12) MUs respectively.The mean treatment time of two modes were consistent (about 2 min).Conclusions The plan qualities of FFF and FF VMAT plans were comparable and both clinically acceptable.The OARs at the edge of radiation field,such as lens,could be spared better using FFF VMAT mode.The total MUs of FFF VMAT plans were higher than FF VMAT plans,yet were delivered within the same time.

ObjectiveTo observe and evaluate the role of cervical cytological examination in 1946 cases in gestation, and at 2 months and 6 months after delivery, and treatment for abnormal cases.MethodsThe thinprep cytologic test samples of 1946 cases from external cervical orifice and cervical cavity were collected. The cytological diagnosis was performed according to TBS-diagnosis and classification system.ResultsIn 1946 samples, there were 160 inflammatory samples (8.2%), including bacterial vaginitis 51 cases (2.6%), trichomonal vaginitis 49 cases (25.%), candidal vaginitis 58 cases (3.0%); typical epithelial cells 105 cases (5.4%), including atypical squamous cells (ASUCS) 70 cases (3.6%), low-grade squamous intraepithelial lesions (LSIL) 29 cases (1.5%), high-grade squamous intraepithelial lesions (HSIL) 5cases (0.2%), the carcinoma in situ 1 case (0.05%); human papilloma virus (HPV) 32 cases (1.6%), including HPV combined with atypical squamous cells 21 cases (1.1%), HPV combined with LSIL 10 cases (0.5%). Large mass of cases with a abnormally result of cervical cytological examination had a normal childbearing, the cases that re-examination after birth showed carcinoma in situ and HSIL treated by conization, and others treated with physical treatment.ConclusionCervical cytology examination has positive effect on prevention and treatment of precancerous changes and carcinoma in gestational women. Cervical lesions less likely get worse during pregnancy. Conservative management is possible if regular cytology, copolscopy and bioposy performed when necessary. Re-examination at two and six months after birth is necessary for determining treatment method.

Recent study demonstrated that insulin-like growth factor-1(IGF-1) could have benefits to improve the learning memory.Exercise can increase IGF-1 level in hippocampus.IGF-1 may mediate exercise inducing learning memory;one of the possible mechanism is that the IGF-1 and brain derived neurotrophic factor(BDNF) has a common regulatory capacity over calcium/calmodulin-dependent protein kinase Ⅱ(CAMKⅡ),mitogen-activated protein kinase Ⅱ(MAPKⅡ) and synapsin-1,and the convergence of multiple signaling pathways mediate synaptic plasticity and improve learning memory.
