The laser-induced breakdown spectroscopy (LIBS) was applied to perform a qualitative elementary analysis on four precious Tibetan medicines, i. e. Renqing Mangjue, Renqing Changjue, 25-herb coral pills and 25-herb pearl pills. The specific spectra of the four Tibetan medicines were established. In the experiment, Nd: YAG and 1 064 nm-baseband pulse laser were adopted to collect the spectra. A laser beam focused on the surface of the samples to generate plasma. Its spectral signal was detected by using spectrograph. Based on the National Institute of Standard and Technology (NIST) database, LIBS spectral lines were indentified. The four Tibetan medicines mainly included Ca, Na, K, Mg and other elements and C-N molecular band. Specifically, Fe was detected in Renqing Changjue and 25-herb pearl pills; heavy mental elements Hg and Cu were shown in Renqing Mangjue and Renqing Changjue; Ag was found in Renqing Changjue. The results demonstrated that LIBS is a reliable and rapid multi-element analysis on the four Tibetan medicines. With Real-time, rapid and nondestructive advantages, LIBS has a wide application prospect in the element analysis on ethnic medicines.

The perioperative urodynamic index and postoperative long-term sexual function were analyzed.Result Pelvic autonomic nerve was preserved in all 18 patients and they have normal urine function and satisfactory long-term sexual function.Conclusion Male patients aged younger than 60 yrs., with rectal carcinoma of Ducks A to C are suitable for receiving PANP radical resection for better maintenance of the urinal and sexual function.

Objective: According to the theory of traditional Chinese medicine, the effect of cervical stimulation on autonomic nervous system activity in humans was investigated.Methods: Healthy young male volunteers were selected as subjects of the trial. The upper cervical spine (C2-5) was stimulated bilaterally with spinal manipulation, and changes in heart rate and heart rate variability were calculated as measures of effects on autonomic nervous system tone. Results: Thirty healthy young male volunteers were tested. It was found that heart rate decreased (R-R interval prolonged) significantly. SDNN and total power spectrum increased significantly, indicating an increase in sympathetic tone. Conclusion: Cervical manipulation can regulate the autonomic nervous system tone in healthy young men, and it suggests a possibility of treating cardiovascular diseases such as arrhythmia with cervical manipulation.

Near-infrared (NIR) was used as rapid analysis method to identify the sulfur fumigated Puerariae Lobatae Radix. NIR spectra of the cross-sectional and longitudinal selection of samples were acquired. Principal component analysis was conducted. The samples were randomly selected. The different pretreatment methods were compared. Discriminant models were established for every type of spectra to calculate the recognition rate. The orthogonal test and nonparametric test were used to test data normality. The result showed that absorbance values of different sections were different due to the different structure, and the raw spectra were analyzed by PCA method. The result founded that the cumulative contribution rate was arrived at 99.2% while the PC numbers were arrived at 3. The pretreatment method based on the MSC + 1D + Savitzky-Golay was the best to establish the model. For the 50 models constructed with cross-section and longitudinal spectra and total spectra, the recognition rate were (94.4 ± 0.66)%, (94.4 ± 0.66)%, (95.3 ± 0.65)%, respectively, and no difference was observed. The NIR method could be used to identify the sulfur fumigated Puerariae Lobatae Radix.

The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

Objective To investigate symptom characteristics and their their prevalence in terminally ill patients with ovarian carcinoma.Methods A retrospective study was carried out based on clinical data of 98 terminally ill patients with ovarian carcinoma who died in our hospital during January 1995 to December 2004.Fifteen most common symptoms were analyzed with a focus on the followings:symptom incidence,survival time after symptom occurrence,regularity of symptom cluster,and common causes of death.Fifteen symptoms were:pain,cachexia,pleural effusion and ascites,dyspnea,fever,intestinal obstruction,renal failure,bone marrow depression,lung infection,hemorrhage,deep venous thrombosis (DVT),intestinal or pancreatic fistula,mycotic infection,jaundice and emergency conditions.Results (1)The most prevalent symptom was pleural effusion and ascites(63%),followed by pain(60%), cachexia(59%),dyspnea(52%)and intestinal obstruction(49 %).(2)The symptom which lasted longest survival time was mycotic infection(77 days),followed by intestinal or pancreatic fistula(75 days), intestinal obstruction(67 days),pain(60 days)and eachexia(60 days).Symptoms such as bone marrow depression,renal failure,dyspnea and emergency conditions were comparatively critical associated with shorter survival times(14,13,12,7 days,respectively).(3)Terminal symptoms occurred typically in clusters,with 4.9?1.5 symptoms per case.Of 98 cases,84 cases(86%)had 4 or more symptoms,with the median survival time of 63 days from the last day of anti-cancer therapy,and a slow death process.The remaining 14 cases(14%)with 3 or fewer symptoms survived only 25 days,of which 10 cases(71%)died of emergency diseases.The survival time for two groups was significantly different(P

Objective To investigate the effect of Epigallocatechin-3-gallate(EGCG)on oxidative stress and inflammatory factors in the kidney tissues of rats with paraquat poisoning,and explore the possible mechanism. Methods Rats were randomly divided into control group(group A), paraquat exposure group(group B),paraquat exposure+low dose of EGCG group(group C),and paraquat exposure+high dose of EGCG group (group D)(n=10 in each group). Kidney tissues were harvested and observed by HE staining. The level of creatinine was tested by biochemical detector. Serum oxidative stress and inflammatory factor level were detected by ELISA method. Oxidative stress in kidney tissue was determined by Western blotting and colorimetry. Inflammatory factor level in renal tissue was tested by real-time PCR. Results Kidney damage was observed in rats of groups B,C,and D. Rats in groups C and D showed less renal injury than group B,and high dose of EGCG(group D)enhanced kidney damage compared to the low dose(group C). Compared with group A,rats in the groups C and D showed lower level of 8-isoprostane,creatinine, interleukin-6(IL-6),and tumor necrosis factorα(TNF-α)in serum and malondialdehyde(MDA),3-nitrotyrosine(3-NT),and TNF-αand IL-6 mRNA in renal tissue in rats with paraquat poisoning,and group D showed the lowest mRNA level of inflammatory factor and oxidative stress. Con-clusion EGCG has protective effects on the kidney of rats with paraquat poisoning,and its mechanism may be related to the reduction of oxida-tive stress and inflammatory reaction in the kidney.
