UNLABELLEDOBJECTIVE; To evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) of qi-yin deficiency phlegm-stasis inter-obstruction syndrome (QYDPSIOS), and to observe its effect on inflammatory factors and fibrinolytic factors.

METHODSBy adopting a randomization grouping, parallel control, and prospective study, 73 T2DM patients of QYDPSIOS were assigned to two groups by random digit table, the Pioglitazone Tablet group (36 cases, as the control) and the JTXZC group (37 cases). All patients maintained their basic therapies and lifestyle as previous after recruitment. Patients in the JTXZC group took JTXZC, 4 pills each time, three times per day, while those in control group took Pioglitazone Tablet, 15 mg each time, once daily. The therapeutic course for all was 8 weeks. The body weight (BW), the height, body mass index (BMI), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR), and scoring of Chinese medicine (TCM) symptoms were observed. Levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG), glycated hemoglobin (HbA1c), tumor necrosis factor alpha (TNF-alpha), nuclear factor kappaB (NF-kappaB), and plasminogen activator inhibitor 1 (PAL-1) were detected. The safety indices such as liver and renal functions and adverse reactions were also observed.

RESULTSCompared with before treatment, BW, BMI, HbA1c, and PBG were obviously lower after 8-week treatment than before treatment in the JTXZC group (P < 0.05). There was no statistical difference in post-treatment BW, BMI, HbA1c, or 2 h PBG between the two groups (P < 0.05). Compared with before treatment, levels of TNF-alpha and PAI-1 were lowered after 8 weeks of treatment in both groups (P < 0.01). The level of NF-kappaB was obviously lowered after 8 weeks of treatment in the control groups (P < 0.05), but it also decreased in the JTXZC group with no statistical difference. The scorings of CM symptoms were somewhat improved after treatment in the two groups (P < 0.01). Besides, better effects were obtained in the JTXZC group (P < 0.05). No severe adverse event occurred in either group during the whole therapeutic course.

CONCLUSIONSJTXZC showed similar therapeutic effect to pioglitazone. Both of them could effectively improve patients' clinical symptoms, the inflammation and fibrinolytic activities in different pathways, with no severe adverse reaction.

Torpor refers to a state in which the metabolic activity in the body of the living animal is greatly reduced during the period of reduced food supply, which is manifested as a substantial decrease in body temperature, metabolic level, and exercise level. Mammals have a strict body temperature regulation system to maintain a constant body temperature. When the energy supply is insufficient for a long time, some mammals will enter a hibernation state. Torpor is very similar to the hibernation state. The research on the mechanism of torpor state is of great significance in aerospace, military medicine and other fields. This review summarizes the specific mechanisms regulating the occurrence of torpor from four aspects: adenylate cyclase activating polypeptide (adcyap) neurons, leptin, pyroglutamylated RFamide peptide (QRFP) neurons, and sympathetic nervous system, aiming to provide ideas for further research on the mechanism of torpor.

RIG-I-like receptors (RLRs) belong to pattern recognition receptors, which perform significant roles in antiviral responses. RLRs can initiate a cascade of signaling transduction that induces the production of type I interferon and activates the interferon signaling pathway, ultimately resulting in antiviral responses. In the course of evolution, viruses have been constantly counteracting host immune systems to facilitate their own survival and replication, and have developed a set of antagonistic strategies. These mainly comprise elusion, disguise and attack strategies to eliminate the activation of RLRs. In virus-infected cells, RLRs recognize viral RNA and then induce antiviral responses. A better understanding of viral antagonistic strategies against RLRs will provide insights into the development of new antiviral medicines. This mini-review concludes that there are three main antagonistic strategies by which RNA viruses can counteract the activation of the RLRs pathway. It aims to provide references and insights for similar studies on viral antagonism in an array of RNA viruses.

Aim To observe the effect of hemodialysis on pharmacokinetics of sparfloxacin in thepatients contracting chronic renal failure. Methods Sparfloxacin concentrations inserum and urine of hemodialysis and non-dialysis patients were measured with a highperformance liquid chromatography method after administration a single oral dose of 200mg sparfloxacin. The pharmacokinetic parameters were computed with the programPKBP-N1.Results The main pharmacokinetic parameters in hemodialysis group wereT1/2(ka) - (1. 25 ?0. 57) h, T1/2(?) = (11. 88?4. 13) h, Tpeak = (4. 18 ? 0. 78) h,Cmax = (0.80 ? 0. 17) mg? L-1 and AUC0-= (6. 90 ? 3. 25) mg?h?L-1, while innon-dialysis group were T1/ 2(ka) = (1. 12 ? 0. 42) h, T1/ 2(?) = (15. 93 ? 5. 20) h, Tpeak =(3. 88 ? 0. 75) h, Cmax = (0. 69 ? 0. 37) mg?L -1, AUC0-= (10.05 ? 4. 13) mg?h?L-l. The original sparfloxacin discharge rats in urine within 24 h were (8. 98 ? 3. 92) % and(10. 58 ? 5. 64) % separately. T1/2(?) and AUC in hemodialysis group were markedly lowerthan in non-dialysis group (P

OBJECTIVE: To realize the automated assessment of the levels of epiphysis of distal radius and ulna by support vector machine (SVM). METHODS: The X-ray films of the left wrist joints were taken from 140 teenagers aged from 11 to 19 years old as training samples. The levels of epiphysis of distal radius and ulna were divided into five developmental levels. Each level contained 28 samples. Another 35 cases were selected as independent verifying samples. SVM classification models of the five developmental levels of epiphysis of distal radius and ulna were established. The internal cross validation was made by leave one out cross validation (LOOCV), while the external validation was made by histogram of oriented gradient (HOG), and then the accuracy (PA) of testing results was calculated, respectively. RESULTS: The PA of SVM, LOOCV and HOG of distal radius epiphyseal level were 100%, 78.6%, and 82.8%, respectively; whereas the PA of SVM, LOOCV and HOG of distal ulna epiphyseal level were 100.0%, 80.0% and 88.6%, respectively. CONCLUSION The SVM-based automatic models of the growth stage of distal ra- dius and ulna appear to have certain feasibility, and may provide a foundation for software development of bone age assessment by forensic medicine.

OBJECTIVETo explore the antitumoral effect of indirubin on androgen-independent prostate cancer PC-3 cells and its possible mechanisms.

METHODSWe measured the inhibitory effect of indirubin on the proliferation of prostate cancer PC-3 cells using MTT assay, detected their cell cycles by flow cytometry, and determined the expressions of the cell cycle regulatory protein cyclin D1 and its related downstream gene c-myc by Western blot.

RESULTSThe viability of the PC-3 cells was significantly decreased by indirubin in a concentration-dependent manner, reduced to 52. 2% and 13. 6% at 5 and 10 µmol/L, respectively. The cell cycle of the PC-3 cells was markedly inhibited by indirubin at 5 µmol/L, with the cells remarkably increased in the G0 and G1 phases and decreased in the S and G2/M phases. Meanwhile, indirubin also inhibited the expressions of cyclin D1 and c-myc in the Wnt signaling pathway.

CONCLUSIONIndirubin can suppress the proliferation of androgen-independent prostate cancer PC-3 cells, which may be associated with its inhibitory effect on the cell cycle and Wnt signaling pathway.

Current study was carried out to optimize the priming condition of Oldenlandia diffusa seeds, and improve germination rate and seed vigor of 0. diffusa seeds under drought conditions. Uniform design was used to optimize the concentration and priming time of three priming materials (PEG, KNO3, GA3). Different concentrations of polyethylene glycol (PEG) was used to simulate drought stress. The seedling was cultured in 1/4 Hoagland medium for 30 d. The results showed that seed priming treatment with 366 mg x kg(-1) GA3 for 1h resulted in significant increase in germination rate, germination index, vigor, root length, plant height and biomass of O. diffusa seeds under drought stress (15% PEG), while seed priming with 3.0% KNO3 for 1 h showed little effect on germination and growth of O. diffusa seeds under drought stress. Seed priming treatment with appropriate GA3 concentration and priming time could enhance seed germination and drought resistance of O. diffusa in seedling stage.

The present study was aimed at investigating the expression of calbindin-D28k (CaBP-D28k) in human fallopian tube, which were collected from 33 childbearing age women undergoing abdominal hysterectomy with adnexectomy for benign disease in the pelvic cavity. These women had normal menstrual cycle and history of normal pregnancy. Isthmus, ampullary and umbrella segments of fallopian tubes were respectively collected. These specimens were divided into 6 groups based on their menstrual cycles: early-proliferative stage (n=6), mid-proliferative stage (n=5), late-proliferative stage (n=5), early-secretory stage (n=7), mid-secretory stage (n=5) and late-secretory stage (n=5). The expressions of CaBP-D28k protein and mRNA in fallopian tubes were determined by immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR) methods. Positive expressions of CaBP-D28k protein and mRNA were observed in human fallopian tubes. There was no significant difference in the expression of CaBP-D28k protein among the isthmus, ampulla and umbrella segments in the same phase of menstrual cycle (P>0.05). However, in the menstrual cycle, the expression level of CaBP-D28k protein in the epithelium was the lowest during the early- and mid-proliferative stages and increased in both the late-proliferative and early-secretory stages (P<0.05), and then decreased in the mid- and late-secretory stages (P<0.05). The expressed CaBP-D28k protein was disposed to gobbets or dispersed sheets in cytoplasm in the early- and mid- proliferative stages, and showed concentrated granules on the top of cells in the late-proliferative and early-, mid-secretory stages. Then in the late-secretory stage redistribution renewed as in the early- and mid-proliferative stages. The CaBP-D28k mRNA obviously increased in the late-proliferative and early-secretory stages (P<0.05). These findings indicate that the expressions of CaBP-D28k protein and mRNA exist in human fallopian tubes and exhibit a cyclic change.
