OBJECTIVETo observe the effect of Ningzhi Capsule (NZC) on blood lipid spectrum in type 2 diabetes mellitus patients complicated with hyperlipemia (DM-HL).
METHODSAdopting randomized, parallel and controlled trail method, a total of 70 DM-HL patients of qi-yin deficiency and phlegm-blood stagnant syndrome type were randomized into two groups. The original medication for lowering blood sugar and blood pressure was unchanged, the trial group received oral administration of NZC 5 tablets, 3 times a day, while the control group received Lipanthgl or Simvastatin depending on their different constituents of blood lipids. After 6 months of treatment, sixty subjects completed the trail while two patients dropped out due to side effect and 8 patients lost follow-up (4 in each group). Levels of blood lipids, blood routine, liver and kidney function and symptoms in patients were detected and compared.
RESULTSAfter treatment, levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), apoprotein B, and lipoprotein a (LPa) lowered, while levels of high-density lipoprotein (HDL-C) and apoprotein A raised in the trial group as compared with those before treatment (P < 0.05, P < 0.01), but showed no difference between the two groups after treatment except HDL level (P > 0.05). Scores of symptoms were also lowered significantly in the trial group (P < 0.01). In the observation period, no abnormal findings in blood and urine routine examination as well as in liver and renal function were found.
CONCLUSIONNZC could lower the blood lipid spectrum and improve the TCM symptoms in DM-HL patients without any adverse reaction.

Objective:To investigate any change in the effective connectivity between the bilateral anterior central gyruses after transcranial magnetic stimulation (TMS).Methods:Twenty-one healthy subjects were examined using resting state functional magnetic resonance imaging (rs-fMRI) before and after receiving continuous theta burst stimulation (cTBS). The brain atlas of the Institute of Automation of the Chinese Academy of Sciences was used for fine partitioning of the bilateral anterior central gyruses. Granger causality analysis was used to compare any changes in the effective connectivity between them.Results:After the cTBS inhibited the right M1 area, significant changes in effective connectivity among the sub-regions of the bilateral M1 area were observed. The effective connectivity of the right upper limb to the left upper limb and the left head to face were weakened, while that of the left upper limb to the right head, as well as of the face to the right upper limb was enhanced.Conclusion:For people whose right M1 area has been inhibited by cTBS, the effective connectivity changes in both upper limb functional areas of the M1 region reflect inter-hemispheric inhibition. Opposite changes were found in the trunk and upper limbs.

To investigate the cell-killing effect and its possible mechanism of rClone30-hDR5 in combination with TRAIL on human hepatic carcinoma (HCC) cell line, first of all, recombinant plasmid pee12.4-hDR5 was introduced into HepG2 cells by liposome transfection. After five rounds of screening by flow cytometry, HepG2 cells expressing high levels of DR5 on cell surface were isolated. The cytotoxicity of TRAIL to selected cells was higher than that of TRAIL to HepG2 cells by MTT method (P < 0.01). The result suggested that the cloned hDR5 gene had biological activity. MTT assay showed that, rClone30- hDR5 in combination with TRAIL more efficiently inhibited the tumor growth of HepG2 cells compared to rClone30-hDR5 or TRAIL in vitro. The results of Annexin V-FITC/PI staining and Quantitative Real-time PCR indicated that rClone30-hDR5 in combination with TRAIL significantly increased the mRNA levels of caspase 3 and caspase 8, and induced the apoptosis of tumor cells. HepG2 cells were infected with rClone30-hDR5 or rClone30 at MOI of 1. The expression of hDR5 on tumor surface increased significantly by rClone30-hDR5 compared to that by rClone30, which contributed to the sensitivity to TRAIL. In conclusion, rClone30-hDR5 in combination with TRAIL has potential application value in cancer treatment.

Nondestructive method of measuring soluble solids content (SSC) of citrus fruits was developed using Fourier transform near infrared reflectance (FT-NIR) measurements collected through optics fiber. The models describing the relationship between SSC and the NIR spectra of citrus fruits were developed and evaluated. Different spectra correction algorithms (standard normal variate (SNV), multiplicative signal correction (MSC)) were used in this study. The relationship between laboratory SSC and FT-NIR spectra of citrus fruits was analyzed via principle component regression (PCR) and partial least squares (PLS) regression method. Models based on the different spectral ranges were compared in this research. The first derivative and second derivative were applied to all spectra to reduce the effects of sample size, light scattering, instrument noise, etc. Different baseline correction methods were applied to improve the spectral data quality. Among them the second derivative method after baseline correction produced best noise removing capability and yielded optimal calibration models. A total of 170 NIR spectra were acquired; 135 NIR spectra were used to develop the calibration model; the remaining spectra were used to validate the model. The developed PLS model describing the relationship between SSC and NIR reflectance spectra could predict SSC of 35 samples with correlation coefficient of 0.995 and RMSEP of 0.79 degrees Brix.

Watermelon is a popular fruit in the world with soluble solids content (SSC) being one of the major characteristics used for assessing its quality. This study was aimed at obtaining a method for nondestructive SSC detection of watermelons by means of visible/near infrared (Vis/NIR) diffuse transmittance technique. Vis/NIR transmittance spectra of intact watermelons were acquired using a low-cost commercially available spectrometer operating over the range 350~1000 nm. Spectra data were analyzed by two multivariate calibration techniques: partial least squares (PLS) and principal component regression (PCR) methods. Two experiments were designed for two varieties of watermelons [Qilin (QL), Zaochunhongyu (ZC)], which have different skin thickness range and shape dimensions. The influences of different data preprocessing and spectra treatments were also investigated. Performance of different models was assessed in terms of root mean square errors of calibration (RMSEC), root mean square errors of prediction (RMSEP) and correlation coefficient (r) between the predicted and measured parameter values. Results showed that spectra data preprocessing influenced the performance of the calibration models. The first derivative spectra showed the best results with high correlation coefficient of determination [r=0.918 (QL); r=0.954 (ZC)], low RMSEP [0.65 degrees Brix (QL); 0.58 degrees Brix (ZC)], low RMSEC [0.48 degrees Brix (QL); 0.34 degrees Brix (ZC)] and small difference between the RMSEP and the RMSEC by PLS method. The nondestructive Vis/NIR measurements provided good estimates of SSC index of watermelon, and the predicted values were highly correlated with destructively measured values for SSC. The models based on smoothing spectra (Savitzky-Golay filter smoothing method) did not enhance the performance of calibration models obviously. The results indicated the feasibility of Vis/NIR diffuse transmittance spectral analysis for predicting watermelon SSC in a nondestructive way.

The present study reports a rare case of Taenia saginata infection, which was initially diagnosed as acute cholecystitis in a Tibetan patient at the Qinghai-Tibetan Plateau pastoral area, China. A 45-year-old female was initially diagnosed with acute cholecystitis at a hospital in China. She had a slight fever, weight loss and constipation and complained of pain in the upper abdomen and left back areas. Increase of monocyte, eosinophil and basophil levels were shown. Taenia sp. eggs were detected in a fecal examination. An adult tapeworm approximately 146 cm in length, whitish-yellow color, was collected from the patient after treatment with traditional Chinese medicine. The adult tapeworm had a scolex and proglottids with genital pores. The scolex was rectangular shape with 4 suckers and rostellum without hooklet. The cox1 gene sequence shared 99.5-99.8% homology with that of T. saginata from other regions in China. The patient was diagnosed finally infected with T. saginata by morphological and molecular charateristics.
