Objective To assess the dlagnostic value of a triple stimulation technique(TST)for benign monomelic amyotrophy(BMA). Methods A total of 15 BMA patients and 15 healthy control subiects were exam-ined with the TST.The latent periods,amplitudes,areas and durations of the negative waves of the compound muscle action potential(CMAP)and motor evoked potential(MEP)induced by the stimulation were recorded,and the de-creasing ratio of amplitudes and areas in the two groups were analyzed. Results There were significant differences in amplitude and area ratios between the BMA patients and the healthy control subjects.Both ratios were significantly lower in the BMA patients. Conclusion TST has some value in diagnosis of BMA.

AIM:To investigate the perfusion parameters using dynamic contrast-enhanced magnetic resonance imaging ( DCE-MRI) in rectal cancer patients so as to explore its potential value in estimating the microvascular condition including perfusion and permeability .METHODS:The data of 38 rectal cancer patients examined with DCE-MRI was ret-rospectively analyzed .The perfusion parameters of carcinoma and normal rectal wall in each case were calculated , inclu-ding volume transfer constant (Ktrans), rate constant of back flux (Kep), extravascular extracellular space fractional volume (Ve) and initial area under curve (iAUC).The mean values of tumor and normal rectal wall , mucinous and nonmucinous carcinoma, poorly and moderately-to-well differentiated carcinoma , case with or without lymph node metastasis were com-pared.RESULTS:All the parameters of rectal cancer were higher than normal rectal wall (P<0.01).No significant difference was found between poorly and moderately-to-well differentiated carcinoma in terms of K trans, Kep and Ve, neither was the case with or without lymph node metastasis .The cases with lymph node metastasis had lower iAUC than those with-out (P<0.05).CONCLUSION:Quantitative perfusion DCE-MRI answered the microvascular perfusion and permeability change of rectal cancer compared with normal rectal wall , besides it could be used to distinguish between mucinous and nonmucinous carcinoma , which demonstrated its value in the evaluation of rectal cancer .However , it should not be recom-mended to predict the degrees of tumor cell differentiation and lymph node metastasis just according to the perfusion param -eters.

OBJECTIVETo examine the differences in food and antioxidant vitamin intake in current non-smokers,light smokers,and heavy smokers.

METHODS51 115 people (24 077 male, 27 038 female) aged above 15 years who had completed providing information on smoking habit and dietary intake, were selected from 2002 national health and nutrition survey.

RESULTSAfter adjustment for geographic areas and age, data showed the smokers ate more light vegetable and alcohol, less dark vegetable and fruit than non-smokers. Male smokers consumed more energetic stuff and macronutrients than non-smokers, but female smokers had opposite trends. Light smokers (LS) consumed less antioxidant than non-smokers (NS) after adjusted for area, age, BMI and energy, with carotene (Male LS = 1824.7 microg, NS = 1964.8 microg; Female LS = 1565.4 microg, NS = 2127.4 microg), thiamin (Male LS = 0.84 mg, NS = 0.85 mg; Female LS = 0.72 mg, NS = 0.74 mg), vitamin E (alpha) (Male LS = 9.2 mg, NS = 9.3 mg; Female LS = 7.4 mg, NS = 8.1 mg), vitamin C (Male LS = 91.2 mg, NS = 94.2 mg; Female LS = 76.9 mg, NS = 87.5 mg).

CONCLUSIONSmokers had a significantly lower overall mean dietary antioxidant vitamin intake than non-smokers. Increasing the daily consumption of variety of fruits and vegetables had been recommended to reduce the risk of chronic diseases.

OBJECTIVETo compare the efficacy and tolerability of the regimen FOLFOX [1eucovorin (LV), 5-fluorouracil (5-Fu) and oxaliplatin] and the regimen PLF (Paclitaxel, leucovorin and 5-Fu) for treatment of advanced gastric adenocarcinoma.

METHODSWe retrospectively studied the clinical data of 132 patients with stage IV gastric adenocarcinoma treated by FOLFOX (group A, n=60) or PLF (group B, n=72). The tumor response rate, toxicity, time to progress (TTP) and overall survival (OS) were compared between the two groups.

RESULTSA total of 544 cycles were administrated in these patients. The overall response rate was 35.0% with FOLFOX regimen and 41.7% with PLF regimen, showing no significant difference between them (P>0.05). The TTP was 6.13-/+1.26 (95%CI, 3.65-8.61) months in group A, and 5.92-/+0.49 (95%CI, 4.97-6.87) months in group B; the OS was 10.67-/+1.55 (95%CI, 7.63-13.71) months in group A, and 10.8-/+3.07 (95%CI, 4.78-16.82) months in group B. Neither TTP or OS showed significant differences between the two groups (P>0.05). Five patients in group A (8.33%) and 8 in group B (11.11%) had grade 3 and 4 leukopenia. The non-hematological toxicities were mostly mild, including nausea, vomiting, stomatitis, diarrhea and alopecia. The main adverse effects were grade 1 or 2 sensory neuritis in FOLFOX group, and alopecia in PLF group, without significant difference between the two groups (P<0.05).

CONCLUSIONBoth FOLFOX and PLF can serve as effective first-line treatment of stage IV gastric adenocarcinoma with good tolerance.

Objective: To establish an echocardiography parameter scoring system for assessing the risk of 1 year re-admission in patients with left ventricular systolic dysfunction (LVSD). Methods: A total of 412 chronic LVSD patients treated in our hospital from 2007-01 to 2016-01 were studied and the end point event was 1 year re-admission. The data included in 280 patients from 2007-01 to 2014-12 for establishing the scoring system and 132 patients from 2015-01 to 2016-01 for verifying the system. Based on 7 echocardiography parameters, the patients were divided into 7 sets of groups: ① Left ventricular diameter (LVD): Group0, n=290 and Group1, n=122;② Mitrial regurgitation (MR): Group0, n=203, Group1, n=138 and Group2, n=71; ③ Tricuspid regurgitation (TR): Group0, n=302, Group1, n=90 and Group2, n=20; ④ LVEF: Group0, n=272 and Group1, n=140; ⑤ Pulmonary artery systolic pressure: Group0, n=282 and Group1, n=130; ⑥ Hydropericardium: Group0, n=347 and Group1, n=65; ⑦ Hydrothorax:Group 0, n=261, Group1, n=86 and Group2, n=65. The parameters were identified by COX regression analysis, weighted value of scoring system was calculate by hazard ratio (HR), predictive value for1 year re-admission was assess by ROC curve and finally, scoring integration was verified by validation data group. Results: The integration score was calculated as follows: LVD>60mm=1 point; TR: Group1=1 point and Group2=3 points; MR: Group1=2 points and Group2=4 points; Hydrothorax: Group1=2 points and Group2=3 points;Hydropericardium=1 point. COX regression analysis indicated that for 1 year re-admission: HR=1.552 in Group1 vs Group0, HR=3.374 in Group2 vs Group0 and HR=4.562 in Group3 vs Group0, all P<0.05. The AUC of ROC for establishing the data was 70.0% (95% CI 0.640-0.761) and for verifying the data was 70.4% (95% CI 0.616-0.792); the best integration score was 4 points. Conclusion: Echocardiography parameter scoring system may better predict the risk of 1 year re-admission in LVSD patients which is superior to single echocardiography parameter.

OBJECTIVETo evaluate the therapeutic effect and applying value of Hegu (LI 4) for inertia of uterus.

Objective To construct and validate a predictive model for the risk of bone metastasis in patients with primary liver cancer. Methods The research was generally divided into two parts: model establishment and model validation. A total of 197 patients with primary liver cancer from January 2018 to June 2018 were selected to be included in the study when building the model, and the nomogram prediction model based on Cox regression was used in the case-control study method. The validation process continued to select 238 patients with primary liver cancer (no bone metastasis) in our hospital (from July 2018 to December 2018) and followed up for 3 years. The information of the prognosis of bone metastasis during the follow-up period was observed and collected to complete the validation. SPSS statistical software and R software were used to complete the data analysis. Results The results of regression analysis at the stage of building the model showed that age, family history of malignant tumor, previous history of hepatitis B, tumor stage, primary focus surgery and tumor differentiation were independent factors affecting the prognosis of patients with bone metastasis (P <0.05). The nomogram clinical prediction model was established by using R software. The prediction model finally included four factors: age, previous history of hepatitis B, primary surgery, and degree of differentiation. The AUC of ROC curve for predicting the risk of bone metastasis was 0.758. Conclusion The nomogram model constructed in this study has a medium to high degree of predictive calibration for predicting the risk of bone metastasis in patients with primary liver cancer within 3 years and is worthy of clinical auxiliary use.

Objective:To investigate the expression of KCTD8 gene in breast ductal carcinoma and its correlation with clinical factors and prognosis.Methods:Immunohistochemistry technology(IHC)were employed to detect protein expression levels of KCTD8 in 27 pairs of breast ductal carci-noma and its paired adjacent tissues.Analyzing the correlation between changes in KCTD8 expres-sion of protein and clinical factors using statistical techniques.RNA expression and methylation data of breast cancer(including intraductal cancer)were analysed from TCGA database.Result:The pro-tein expression of KCTD8 gene in 27 pairs of breast ductal carcinoma tissues showed a decreasing trend compared to adjacent tissues(P＜0.05),and the decreased expression level of protein was cor-related with the tumor size of patients(P＜0.05).The analysis results of the TCGA database indicate that the expression and hypemethylation of KCTD 8 gene in breast cancer(including intraductal can-cer)tissues affected the prognosis of patients.Conclusion:The reduced protein expression level of KCTD8 gene in breast ductal carcinoma may be involved in the development and affect the prog-nosis of patients.

OBJECTIVETo describe the prevalence of body overweight and obesity and its changes among Chinese people during 1992-2002, and to provide scientific basis for developing intervention strategies for obesity in China.

METHODSThe data from "1992 China third National Nutrition Survey" (78,704 subjects, 38,323 male and 40,381 female) and from "2002 China National Nutrition and Health Survey" (209,849 subjects, 101,377 male and 108,472 female) were used in this study. The overweight and obesity were defined by using WHO Z-score criteria for children younger than 7 years old, Chinese age-, sex-specific BMI criteria for children aged 7-17 years, and Chinese BMI criteria for adults.

RESULTSThe overall prevalence of overweight and obesity of Chinese people was increased by 38.6% and 80.6%, respectively during the period of 1992-2002. The prevalence of overweight and obesity of Chinese people aged 0-6 years, 7-17 years, 18-44 years, 45-59 years and above 60 years was increased 31.7%, 17.9%, 66.7%, 45.2% and 43.7%, respectively. The increase of the prevalence of overweight and obesity was higher in girls younger than 6 years than their male counterparts, while among other age groups, that were higher in boys than girls. The prevalence of overweight and obesity among people living in rural areas was lower than that of their urban counterparts, while the increment of overweight and obesity prevalence among rural people was greater than that of their urban counterparts. It was estimated that another 70 million overweight and 30 million obese Chinese people emerged in China from 1992 to 2002.

CONCLUSIONThe prevalence of overweight and obesity of Chinese people was increased rapidly in the past decade, which had affected 260 million Chinese people. It would continue to increase in the near future if effective intervention measures have not been taken.
