Objective:By applying moxibustion to the eight confluent points in different periods of time,to observe the changes in thermal pain threshold latency of acupoints based on Fei Teng Ba Fa.Methods:A total of 468 healthy college student volunteers received moxibustion at the eight confluent points in three different periods of time,i.e.Chen (7:00-9:00),Wu (11:00-13:00) and Xu (19:00-21:00).The thermal pain threshold latency was adopted to measure the changes in pain threshold of the eight confluent points under different conditions (different periods of time,different genders,different acupoints and different states of the acupoints) based on Fei Teng Ba Fa.Results:Finally,thirty subjects dropped out and 438 subjects were included.The comparison of thermal pain threshold latencies of the eight confluent points in the same opening or closing state based on Fei Teng Ba Fa:latencies of the closing points and adjunct points were significantly different in different periods of time (P＜0.05);the latencies of the males were significantly longer than those of the females (P＜0.05);there was no significant difference in the latency between the left and right sides (P＞0.05);in the female group,there was a significant difference in the latency between the lower-limb points and the upper-limb points (P＜0.05).The comparison of thermal point threshold latencies of the eight confluent points in different opening or closing state:in the period of Wu (11:00-13:00),the latencies of the opening points were significantly longer than those of the closing points and adjunct points (P＜0.05);for men,their opening and closing points had significantly longer thermal pain threshold latencies than their adjunct points (P＜0.05);despite the gender,the latencies of the upper limb opening and closing points were significantly longer than the latency of the adjunct points (P＜0.05);in the female group,the latencies of the lower-limb opening points were significantly shorter than those of the lower-limb closing and adjunct points (P＜0.05).Conclusion:Based on Fei Teng Ba Fa,the pain thresholds of the eight confluent points vary in different periods of time,gender,acupoint location and opening/closing state,which can be taken as the evidence of making time-based acupuncture-moxibustion prescriptions.

The contents of schisandrin, schizandrin A, B and C were determined by HPLC, and the effects of the climate factors and altitude on lignin contents were analyzed in order to select the optimal cultivation area of S. chinensis. The lignin contents were analyzed by HPLC using a ZORBAX SB-C18 column (4.6 mm x 250 mm, 5 microm). The column temperature and detection wave length were set at 35 degrees C and 254 nm, respectively. Methanol-water was used as the mobile phase in gradient elution mode and the flow-rate was 1.0 mL min(-1). The method had a good repeatability, stability and accuracy. The correlation of climate factors and lignins contents was analyzed by SPSS software. The results showed that the schizandrin A content in S. chinensis fruits were higher than 0.4% in Ji'an, Liuhe, Antu and Fusong in Jilin province, which met the quality requirement. It had significant linear negative correlation relationship between schisandrin, schizandrin A, B and altitude, the contents decreased with the increase of altitude. The significant negative linear fitting coefficient was 0.844 1 between schisandrin and altitude; but it had not significant correlation between schizandrin C and altitude. A significant positive correlation of climate factors and the contents of S. chinensis lignins were mainly the temperature factors (the average annual temperature, the highest temperature in July, the average temperature in July, the highest temperature in January, the average temperature in January) and precipitation factor (average annual precipitation), which reveals that higher temperature and precipitation were helpful to the formation and accumulation of lignins of S. chinensis. So the cultivation area of S. chinensis should be in the low elevations region with warm and rainy climate.

Objective To investigate SLC25A13gene mutation in neonatal intrahepatic cholestasis caused by citrin defi-ciency (NICCD). Method A total of 17 children with NICCD were collected. PCR-RFLP method was used to analyze the most common eight mutations of SLC25A13 gene in Chinese populations and results were analyzed together with routine laboratory examinations. Results In the 17 NICCD patients, there were six cases of homozygous mutation, three cases of compound heterozy-gous mutation and eight cases of single heterozygous mutation in SLC25A13 gene. Three kinds of mutations detected were 851del4 (73.1%), 1638ins23 (11.5%) and IVS6+5G>A (15.4%). The seventeen cases showed classical NICCD symptoms of low birth weight, pathological jaundice. And laboratory data suggested liver dysfunction, hyperbilirubinemia, hyperbileacidemia, hy-poproteinemia, hypoglycemia, coagulation disorders, hyperlactacidemia and hyperammonemia. Conclusions 851del4, 1638ins23 and IVS6+5G>A are hot spots of SLC25A13 gene mutation in Chinese populations. PCR-RFLP is a rapid, convenient and reliable technology for NICCD molecular diagnosis.

Objective To study the changes and correlation of serum interleukin-17,-6 and-8 (IL-17,IL-6 and IL-8),c-reactive protein (CRP),tumor necrosis factor alpha (TNF-α) of patients with chronic obstructive pulmonary diseases (COPD),and discuss the role and clinical significance of these factors in the occurrence and development of COPD.Methods 100 COPD patients were selected (COPD group),and 50 healthy elderly people in the same period in outpatient medical examination were served as control (control group).The levels ofIL-17,IL-6 and IL-8,CRP,TNF-α in serum were detected with ELISA method.Results The serum levels of IL-17,IL-6,IL-8,CRP and TNF-α of patients in COPD group were higher than those in the control group (P ＜ 0.01),and of patients with acute aggravating period were higher than those of patients with stable period (P ＜ 0.05 or P ＜ 0.01).Pearson correlation analysis showed there were positive correlations among IL-17,IL-6,IL-8,CRP and TNF-α (P ＜ 0.05) Conclusion The serum levels of IL-17,IL-6,IL-8,CRP and TNF-α of COPD patients have abnormal increased,and will increase with the rise of the illness severity.The above factors may be involved in the airway in patients with acute inflammatory reaction and the development process.

Objective To explore a simpler, more economic and reproducible method to reproduce a model of high oxygen induced acute lung injury (HALI) in rats. Methods An animal feeding box equipped with a controllable high oxygen was designed. 100 Sprague-Dawley (SD) rats were divided into normal control group and HALI group by random number table method, with 50 rats in each group. Each group was randomly subdivided into five subgroups according to the duration of exposure to high oxygen, namely 0, 24, 48, 72 and 96-hour subgroups, with 10 rats in each subgroup. The rats in normal control group were kept in cages with ambient air, and the rats in HALI group were kept in an oxygen tank in which the oxygen concentration was higher than 90% volume ratio, with the temperature maintained at 25-27 ℃, humidity of 50%-70%, and CO2 concentration < 0.5% for 23.5 hours every day. The arterial blood of rats was collected for analysis of blood gas at all time points, and the oxygenation index (OI) and respiratory index (RI) were calculated. Then the rats were sacrificed and the right lung was harvested, which was sectioned and stained with hematoxylin and eosin (HE). The changes in histopathology were observed with light microscopy, and pathological score was recorded. The left lung was harvested for the measurement of the wet/dry weight ratio (W/D). Results With the prolongation of high oxygen exposure time, the degree of lung injury in HALI group was gradually increased, and the degree of derangement of alveolar structure appeared in an increasing degree, with destruction of the alveolar wall, widening of alveolar space, and appearance of edema, and inflammatory cell infiltration. A small quantity of red blood cells exudation could be found in some rats. The pathologic changes were most obvious at 48-72 hours after exposure. With the prolongation of high oxygen exposure time (0, 24, 48, 72, 96 hours), the OI (mmHg, 1 mmHg = 0.133 kPa) in HALI group was gradually decreased (446.67±29.93, 306.19±37.23, 269.70±29.00, 253.81±43.40 and 245.58±35.25), RI, pathological score of lung tissue and W/D ratio were gradually increased [RI: 0.25±0.04, 0.31±0.06, 0.38±0.06, 0.46±0.07 and 0.44±0.03; pathological score of lung tissue: 0.00±0.00, 0.90±0.74, 2.90±1.20, 4.70±1.57 and 4.80±1.23; lung W/D ratio: 3.84±0.61, 4.14±0.46, 4.56±0.34, 5.32±0.27 and 5.18±0.25]. Statistically significant differences were found in 72-hour group as compared with that of other groups (all P < 0.05), while no significant difference was found between 96 hours and 72 hours groups (all P > 0.05). There were significant differences in changes between 24, 48, 72, and 96 hours as compared with those of the normal control group: OI (mmHg): 24 h 306.19±37.23 vs. 435.65±25.34 and 96 h 245.58±35.25 vs. 465.42±24.75; RI: 24 h 0.31±0.06 vs. 0.24±0.04 and 96 h 0.44±0.03 vs. 0.24±0.06. The same as true in pathological scores of lung tissue: 24 h 0.90±0.74 vs. 0.00±0.00 and 96 h 4.80±1.23 vs. 0.00±0.00; lung W/D ratio: 24 h 4.14±0.46 vs. 3.79±0.44 and 96 h 5.18±0.25 vs. 4.12±0.91, all P < 0.05. Conclusions A self-designed high oxygen box is simple, easy to operate and reproduction of HALI model can be attained. Sustained exposure to high concentrations of oxygen (≥ 90%) for 24 hours can replicate the HALI model successfully, and the most serious injury appears at 48-72 hours after exposure.

Medicinal values and their chemical bases of Paris (Trilliaceae) are reviewed. Paris plants include 40 species and varieties. Among them, 18 ones are medicinal plants with similarity in traditional uses. Fourteen species have been studied phytochemically, which led to isolation of 207 compounds including 121 steroidal saponins. These saponins are major active constituents from Paris plants, which can explain the traditional uses of the plants to treat cancer, malignant boil, bleeding, gastritis, and so on. The similarity in medicinal uses and chemical constituents of Paris plants implies the possibility of resource substitution among these species. It is worth to further investigate Paris plants in chemical constituents, pharmacological activity, biological property, and toxicology.

To investigate the distribution of the genes of two major metallo-beta-lactamases (MBL; i.e., IMP and VIM) and class 1 integrons (intI) in the clinical imipenem-resistant Pseudomonas aeruginosa, a total of 65 isolates, from a university hospital in Sichuan between December 2004 and April 2005 were screened for MBL genes by PCR using primers specific for bla ( IMP-1 ), bla ( VIM ) and bla ( VIM-2 ) genes. The MBL-positive isolates were further assessed for class 1 integrons by PCR using specific primers. The nucleotide sequences of several PCR products were also determined. The results revealed that the bla ( VIM ) gene was found in 81.5% (53/65) of all isolates, bla ( VIM-2 ) gene was found in only 1 isolate and the intI gene was observed in 45.3% (24/53) of bla ( VIM )-positive isolates. One isolate carried simultaneously both bla ( IMP-1 ) and intI genes, and to the best of our knowledge this is the first report of such isolate in southwest China. These observations highlight that the genes for VIM beta-lactamase and class 1 integrons were predominantly present among the imipenem-resistant P. aeruginosa tested, confirming the current widespread threat of imipenem-resistant, integron-borne P. aeruginosa.
