OBJECTIVE: To observe the efficacy and safety of electroacupuncture (EA) on improving mini-mental state examination (MMSE) in patients with Alzheimer's disease (AD), and to evaluate the efficacy during follow-up visit. METHODS: Forty patients were randomly divided into a treatment group and a control group, 20 patients in each one (3 patients dropped off in the treatment group and 4 patients in the control group). The patients in the treatment group were treated with acupuncture at Baihui (GV 20), Fengfu (GV 16), Shenting (GV 24), Taiyang (EX-HN 5), Shangyintang (Extra 3) and Dazhong (KI 14); besides, EA was applied at Taiyang (EX-HN 5), Baihui (GV 20) and Shenting (GV 24) with dilatational wave, 10 Hz/50 Hz in frequency, 0.5 to 5.0 mA in intensity, once every two days, three treatments per week. The patients in the control group were treated with oral administration of donepezil hydrochloride tablets, once a day, taken before sleep. The treatment was given for 12 weeks in the two groups. The MMSE was evaluated before treatment, 12 weeks±3 days into treatment, and 24 weeks±7 days after treatment, respectively. RESULTS: The difference of total score of MMSE before and 12 weeks±3 days into treatment was not significant between the two groups (>0.05); the total score of MMSE after treatment was higher than that before treatment (both <0.05); compared before treatment, the short-term memory score was increased in the treatment group (<0.05), and the increasing range was superior to that in the control group (<0.05). Compared before treatment, the total score of MMSE in the two groups were reduced 24 weeks ±7 days after treatment (both <0.05), and the reduction in the treatment group was less than that in the control group (<0.05); the differences of short-term memory score before and after treatment was significant between the two groups (<0.05). No adverse reaction occurred in the two groups. CONCLUSION The effect of EA on improving MMSE in patients with AD is similar to donepezil supported by evidence-based medicine. The effect of EA may have a certain continuous effect, and may have advantages in instantaneous memory. In addition, the EA is safe.

OBJECTIVETo explore the secure resection margin (RM) of hepatectomy for primary liver cancer (PLC) with the coexistence of cirrhosis or hepatitis by studying the correlations of the resected liver parenchyma volume with postoperative liver function, complication and RM clinically.

METHODSThe volume of tumor and the surrounding liver in resected liver specimen was measured and calculated in continuous 76 PLC patients prospectively, and the total liver parenchyma volume was measured and calculated using computed tomography (CT) images in former 40 patients. Under ideal circumstances, the surrounding liver volume, which would be resected theoretically, was calculated according to various sizes of tumors and RMs. The correlations of the resected liver volume or hepatic parenchyma-resected rate (HPRR) with postoperative liver function, complication and RM were analysed.

RESULTSThe RM was (5 +/- 7) mm in 76 patients. The volume of the tumors and the surrounding liver in the specimens were (107 +/- 203) cm(3) and (153 +/- 120) cm(3), respectively. In 40 patients, the total nontumorous liver volume using CT images was (1079 +/- 179) cm(3), and HPRR was (14 +/- 9)%. There were statistically significant differences in HPRR (P < 0.05) between three groups with complication score 0, 1-2 and 3-6 points, the value of the first group were lower than that of the third group at the level P < 0.05. The significant factors affecting liver function and complication are HPRR, the size of operation, the time of hepatic portal occlusion and the resected liver volume (P < 0.05) apart from preoperative liver function.

CONCLUSIONSWhen hepatectomy was performed in PLC patients with preoperative liver function of Child A grade and the coexistence of cirrhosis or hepatitis, 30% HPRR was a lower limit for greatly increasing the chance of developing serious postoperative complications, while 20% HPRR was a safe upper limit for achieves quick postoperative recovery or developing only a few mild complications. When PLC patients without macroscopic tumor thrombi or macrosatellites undergo hepatectomy, 10 mm RM is enough to ensure sufficient liver function residue and achieve complete micrometastasis clearance in liver parenchyma surrounding the lesion if the diameter of a tumor is less than 10 cm and 6 mm RM is enough to ensure sufficient liver function residue and obtain 99% micrometastasis clearance if the diameter of a tumor is greater than 10 cm, while with macroscopic tumor thrombi or macrosatellites, 20 mm RM is enough to ensure sufficient liver function residue and achieve 99% micrometastasis clearance if the diameter of a tumor is less than 6 cm.

OBJECTIVETo confirm the malignant phenotype of hepatocarcinoma cell (HCC) lines at various stages of differentiation (MHCC97L, MHCC97H and HCCLM3) and to explore their expression levels of cancer stem cell (CSC) markers.

METHODSThe invasive and proliferative properties of each HCC line were assessed by transwell assay and the Cell Counting Kit-8 (CCK-8) colorimetric assay. Sensitivity to chemotherapy was assessed by treatment with oxaliplatin and determination of the half inhibitory concentration (IC50). The expression of CD90, EpCAM and CD24 was measured by flow cytometry.

RESULTSThe number of cells that migrated through the invasion assay membrane were significantly different between the three HCC lines: HCCLM3 (30.57 +/- 8.95) more than MHCC97H (21.33 +/- 4.17) more than HCC97L (9.33 +/- 3.85), P less than 0.01. The IC50 was significantly different between the three HCC lines: HCCLM3 (36.57 +/- 6.95) mumol/L more than MHCC97H (26.35+/-3.88) mumol/L more than MHCC97L (17.68 +/- 3.25) mumol/L. The CSC marker with the highest expression on all three HCC lines was CD90 (HCCLM3: 0.92% +/- 0.21%, MHCC97H: 1.98% +/- 0.23%, and MHCC97L: 2.55% +/- 0.34%), followed by EpCAM (2.11% +/- 0.32%, 3.23% +/- 0.18%, and 4.38% +/-0.49%, respectively), and CD24 as the lowest (0.68% +/- 0.37%, 1.22% +/- 0.26%, and 1.36% +/- 0.24%, respectively).

CONCLUSIONHigher expression of CSC markers on HCC lines is associated with a stronger invasive ability and higher sensitivity to chemotherapy.

Objective To explore the value of hippocampus hydrogen proton magnetic resonance spectrum analyzes (1 H-MRS) for the diagnosis of temporal lobe epilepsy (TLE) in children.Methods Singa HDe GE company to attain the 1.5T magnetic resonance imaging apparatus was used to analyze the conditions of 30 cases of children with TLE and the other 30 healthy controls received brain MRI and 1H-MRS check.The hippocampal N acetyl aspartate (NAA),creatine (Cr),and the choline (Cho) concentration were observed; NAA/(Cho + Cr),the ratio of NAA/Cr and NAA/Cho were analyzed.The analysis of biochemical components in the hippocampus was performed on the affected sides and the healthy sides of TLE group and the sides of the healthy control group,respectively.Results Hippocampus were anormal by combining MRI and MRS in 28 cases.Levels of NAA/(Cho + Cr),NAA/Cho,and NAA/Cr in the trouble sides of the TLE group had the remarkable statistical significance compared with the normal sides,and the healthy control group (all P ＜ 0.05),but there was no remarkable statistic significance between the normal sides and the healthy control group (all P ＞ 0.05).Nineteen cases had been confirmed by surgery,and postoperative pathological changes:brain surface were wavy,cortex were uneven;there were giant neurons,immature neurons,and scattered across the deformity of neurons in the cortex.A small amount of ectopic neurons can be seen in white matter.Conclusions In the TLE children,the reduction of NAA/(Cho + Cr) value of the side hippocampus may help diagnose the hipppcampal sclerosis earlier,and can provide significant evidence for the diagnosis and treatment of TLE in children.

OBJECTIVEData on traffic accident from year 2000 to 2002 were collected and testified. Epidemiological study was carried out to find the main risk factors of traffic accident.

METHODSThe spatial distribution was conducted by means of Geographic Information System (GIS) and were marked on Shanghai digitalized map with different layers by different colors.

RESULTSResults showed that during 2000, 2001 and 2002, 69,669 , 68,894, and 47,088 traffic accident episodes occurred in Shanghai, resulting in 1747, 1724, 1557 deaths respectively with direct economic lost: 2.1, 2.4, 3.0 billion RMB. The main risk factors causing traffic accident deaths would include drinking alcohol before driving, fatigue and speeding. The leading causes of death were head injury and complex injury of body. GIS showed that there was a homocentric circle with more traffic accidents in downtown city, but more deaths in the urban city. Disease burden caused by traffic accident was very heavy.

CONCLUSIONIn Shanghai, traffic accident has great impact on social and economic issues thus should be controlled effectively. Focus should be layed on control of traffic accident in downtown area and to decrease the number of deaths related to traffic accident in the urban area.

Objective To predict the monthly reported echinococcosis cases in China with the autoregressive integrated mov-ing average(ARIMA)model,so as to provide a reference for prevention and control of echinococcosis. Methods SPSS 24.0 software was used to construct the ARIMA models based on the monthly reported echinococcosis cases of time series from 2007 to 2015 and 2007 to 2014,respectively,and the accuracies of the two ARIMA models were compared. Results The model based on the data of the monthly reported cases of echinococcosis in China from 2007 to 2015 was ARIMA(1,0,0)(1,1, 0)12,the relative error among reported cases and predicted cases was-13.97%,AR(1)=0.367(t=3.816,P<0.001),SAR (1)=-0.328(t=-3.361,P=0.001),and Ljung-Box Q=14.119(df=16,P=0.590).The model based on the data of the monthly reported cases of echinococcosis in China from 2007 to 2014 was ARIMA(1,0,0)(1,0,1)12,the relative error among reported cases and predicted cases was 0.56%,AR(1)=0.413(t=4.244,P<0.001),SAR(1)=0.809(t=9.584, P<0.001),SMA(1)=0.356(t=2.278,P=0.025),and Ljung-Box Q=18.924(df=15,P=0.217).Conclusions The different time series may have different ARIMA models as for the same infectious diseases.It is needed to be further verified that the more data are accumulated,the shorter time of predication is,and the smaller the average of the relative error is.The estab-lishment and prediction of an ARIMA model is a dynamic process that needs to be adjusted and optimized continuously accord-ing to the accumulated data,meantime,we should give full consideration to the intensity of the work related to infectious diseas-es reported(such as disease census and special investigation).

Objective To investigate the value of narrow band imaging (NBI) endoscopy in the detection of laryngeal cancer and its precursor lesions.Methods Between December 2008 and July 2009, a total of 122 consecutive patients with suspected precancerous or cancerous lesions of the larynx were enrolled in this study.High performance endoscopic system equipped with the white light mode and NBI mode was introduced in the examination of larynx.Full pharyngeal and laryngeal examination was performed first under white light endoscope and then under NBI. Each lesion was observed by NBI endoscopy and classified according to the detailed morphologic findings of epithelial microvessels. Histological results were then compared to the corresponding white light and NBI images.Results Among the 122 patients, a total of 149 lesions were detected by white light and NBI modes.The histological diagnoses of these lesions were as follows:16 laryngeal polyp, 7 laryngitis, 24 simple hyperplasia, 17 mild dysplasia, 6 moderate dysplasia, 6 severe dysplasia, 9 carcinoma in situ, 64 invasive cancer. The diagnostic accuracy by NBI for the laryngeal lesions was 90.6% (135/149), which was significantly higher than that of white light (75.2%, 112/149, X~2 = 12.514,P <0.001).The sensitivity of NBI and white light to detect laryngeal carcinoma was 93.2% (68/73) and 68.5% (50/73), respectively (X~2 = 14.317, P < 0.001).Conclusions NBI endoscopy was a promising tool for the differentiation of non-malignant from malignant laryngeal lesions in vivo by detection of the morphology of mucosal capillary vessels.NBI endoscopy was easy to application in the routine pharyngolaryngeal examination with high sensitivity, and facilitated to improve the abilities of preoperative diagnosis and postoperative surveillance.

Background:Clinical outcomes of undifferentiated arthritis (UA) are diverse,and only 40 ％ of patients with UA develop rheumatoid arthritis (RA) after 3 years.Discovering predictive markers at disease onset for further intervention is critical.Therefore,our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.Methods:We performed a prospective,multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals.Clinical and serological parameters were obtained at recruitment.Follow-up was undertaken in all patients every 12 weeks for 2 years.Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.Results:A total of 234 patients were recruited in this study,and 17 (7.3％) patients failed to follow up during the study.Among the 217 patients who completed the study,83 (38.2％) patients went into remission.UA patients who developed RA had a higher rheumatoid factor (RF)-positivity (42.9％ vs.16.8％,x2=8.228,P=0.008),anti-cyclic citrullinated peptide (CCP) antibodypositivity (66.7％ vs.10.7％,x2 =43.897,P ＜ 0.001),and double-positivity rate of RF and anti-CCP antibody (38.1％ vs.4.1％,x2 =32.131,P ＜ 0.001) than those who did not.Anti-CCP antibody but not RF was an independent predictor for RA development (hazard ratio 18.017,95％ confidence interval:5.803-55.938;P ＜ 0.001).Conclusion:As an independent predictor of RA,anti-CCP antibody should be tested at disease onset in all patients with UA.
