Objective To demonstrate the result that progression of disease and prognosis of gastrointestinal cancer patients are correlated with the expression of the cluster and the abundance of lost goodwill target (LGT) fingerprint. Methods To research the period of survival and the time of death, 61 patients treated by SELDI (Surface enhanced laser desorption/ionization-time of flight-mass spectrometer)were involved in. According to the fingerprint spectrum obtained by SELDI and the appearance of fingerprints of LGT, these patients were divided into four groups namely non-peak, single-peak, double-peak, tri-peak and multi-peak groups. By means of Multi-factor analysis of variance and Cox regression analysis of risk, we compare four groups each other so as to find out one group in which patients have the greatest risk of death.Results Among the fingerprint spectrums of patients suffered from gastrointestinal cancer, which were obtained by SELDI, the patients with negative expression of LGT had low risk of death, which were lower than those of single-peak and double-peak groups, especially lower than those of tri-peak and multi-peak groups;the risk of death among the tri-peak and multi-peak groups were much higher than single-peak, the difference had statistical significance (P ＜0.05), and the death rate is rather high. Conclusion Among the serums from cancer patients tested by SELDI, the expression of LGT with tri-peak and multi-peak suggested that patient' s state of illness is about to deteriorate. This kind of fingerprint spectrum can be regarded as positive indicators,and the negative expression of LGT suggested that patient will have a good prognosis with a very low risk of death in the near future.

Objective To investigate the changes of plasma free carnitine (FC) concentrations in preterm infants supplemented with L-carnitine, and to provide a reference for routine preterm infants L-carnitine supplements. Methods A total of 99 preterm infants supplemented with 10 mg/(kg·d) L-carnitine on days 2 and 5 after birth, and 65 full term infants from Department of Neonatology, the Fifth People′s Hospital of Dongguan during July 2014 to December 2015 were recruited in this study , and filter-paper blood spots were collected by heel prick on days 1, 3 and 7. FC was measured using electron spray ionization (ESI) tandem mass spectrometry (MS-MS). Results Concentrations of FC decreased steadily from day 1 to day 7 in full term infants , while it remained the same level during the first week after birth as at birth. Additionally, concentrations of FC were significantly higher in preterm infants than full term infants on day 1 after birth. Conclusions The reasonable L-carnitine supplements may keep the levels of plasma FC at the levels at birth , which is important for fatty acid metabolism in preterm infants.

72 cases of treatments on insomnia were recorded in the medical books of Ming and Qing dynasties(A.D.1368～1911 years).The compatibility regularity of treating insomnia in these 72 cases were statistically analyzed with frequency and the R type cluster analysis methods. Combining the data and modern recognition, compatibility and medication regularity of treating insomnia was further analyzed.

Objective To investigate the clinical characteristics and surgical management of adult presacral tumors.Methods The clinical data of 24 patients with adult presacral tumors from 2007 to 2012 were retrospectively analysed.All patients were diagnosed by digital rectal examination and imaging examination before operation.Seventeen patients with via sacrococcygeal approach,4 patients with via abdominal approach,and 3 patients with via combined abdominal and sacrococcygeal approach.Results The incision of 22 patients primary healing.There were 2 patients with postoperative incision infections,after dressing change cure.No patients died during perioperative period.Twenty patients were followed up for 3-17 months,1 patient with via abdominal approach recurrenced,and was healed after a second surgical resection.Conclusions Digital rectal examination and imaging examination are the main methods for diagnosis of adult presacral tumors.Most adult presacral tumors can be resected through sacrococcygeal route.

Objective To evaluate the acute side effects and efficacy of three dimensional conformal radiotherapy(3DCRT) combined with chemotherapy(CT) for locally advanced non small cell lung cancer(LANSCLC). Methods From Sept. 2000 to Dec.2001,24 patients with LANSCLC were treated with three dimensional conformal radiotherapy combined with chemotherapy navelbine+cisplatin NP. Results The overall response rate(CR+PR)was 91.7% for the primary tumor, and 100% for metastatic mediastinal lymph nodes.The leucopenia rate was 95.8%(54.2% grades 3,4). Acute radiation esophagitis occurred in 54.2% of patients(Grades 1,2). Acute radiation pneumonitis was observed in 12.5% of patients (Grades1,2). Conclusions 3DCRT combined with CT is well tolerated in most patients with LANSCLC. Its early responses are milder than the conventional radiotherapy combined with chemotherapy . Remote results await further follow up.

The paper is to report the observation of pharmacokinetic changes of the characteristic ingredients in the combinations of different-dose herbs of Shaoyao-Gancao decoction. After the establishment of HPLC analytical method of plasma effective constituents, rats were orally administered with different-dose herbs of Shaoyao-Gancao decoction. Blood samples at different times after administering these decoctions were collected, and then were analyzed by HPLC fingerprints technology. Pharmacokinetic parameters of characteristic peaks were analyzed by SPSS 15.0 software and DAS 2.0. At last, we looked for the correlation of those pharmacokinetic parameters and the dosage of Gancao. The best dose of Shaoyao-Gancao decoction was at the ratio of 4 to 4, which was consistent with the dose commonly used in ancient times. The absorption of characteristic peaks from Shaoyao-Gancao decoction was related with the dosage of Gancao, and there existed interaction between each characteristic ingredients. There existed the right dose-ratio of Shaoyao and Gancao to get the best effect. The absorptions of effective constitutents were mutual waxing and waning in order to increase biological effects together. It's demonstrated the compatibility connotation at a right dose-ratio of Shaoyao-Gancao decoction through the angle of pharmacokinetics.

Objective To observe the clinical efficacy of Huoxue Rongluo Particles combined with acupuncture in the eight confluent points of spastic cerebral infarction paralysis and its effects on Glu and Asp levels of serum. Methods Totally 60 patients were divided into two groups: the experimental group and the control group. Both groups received basic Western medicine treatment, and the experimental group received Huoxue Rongluo Particles additionally, one dose a day for two times orally taken; Acupuncture was on eight confluent acupoint, every two days. 15 d is a treatment course, with 6 courses in total. Clinical spasticity index (CSI) and TCM symptom scores before treatment and the treatment of half month, 1 month, 3 months were observed. The levels of Glu and ASP in serum were detected, and TCM clinical efficacy was observed. Results The CSI score, levels of Glu and Asp in serum and TCM symptom scores of the patients after half-month, one-month, and three-month treatment were lower than those before treatment (P<0.05, P<0.01). There was no statistical significance in CSI score after half month treatment between the two groups (t=0.329, P=0.743). The CSI score in the experimental group after one-month and three-month treatment was lower than the control group (t=-2.636, P=0.024; t=-4.213, P=0.021). There was statistical significance in the levels of Glu and Asp between the two groups after half-month and one-month treatment (P<0.05, P<0.01). There was no statistical significance in the levels of Glu and Asp in the two groups after three-month treatment (P>0.05). The TCM symptom scores in experimental group was lower than the control group after half-month, one-month and three-month treatment (P<0.05). The total TCM effective rate was 86.67% (26/30) in experimental group, and 80.00% (24/30) in the control group, with the experimental group better than the control group (P<0.05). Conclusion Huoxue Rongluo Particles combined with acupuncture eight confluence acupoints in the treatment of spastic cerebral infarction paralyzed patients can relieve spasm degree, improve TCM clinical symptoms, which mechanism may be related to reducing serum excitatory neurotransmitters.

Objective To observe the influence of needling the Eight Confluent Points plus Huo Xue Rong Luo granules on the levels of gamma-aminobutyric acid (GABA) and glycine (Gly) in patients with spastic paralysis after cerebral infarction. Method Sixty patients with spastic paralysis after cerebral infarction were randomized into a treatment group and a control group, 3 0 cases each. The control group was intervened by basic treatment, while the treatment group was by Huo Xue Rong Luo granules plus acupuncture at the Eight Confluent Points in addition to the basic treatment, for 6 treatment courses in total. Before the treatment, and after half-a-month, 1-month, and 3-month treatments, the Chinese Stroke Scale (CSS) and activities of daily living (ADL) were evaluated, the levels of GABA and Gly were detected by using high performance liquid chromatography (HPLC), and the therapeutic efficacies were compared. Result After half-a-month treatment, the CSS score dropped significantly in both groups (P<0.01), and the between-group difference was statistically significant (P<0.01);the ADL score (Barthel Index score) increased markedly in both groups (P<0.01), and the between-group difference was statistically significant (P<0.01); the level of serum GABA increased significantly in both groups (P<0.05), and the between-group difference was statistically significant (P<0.05);the level of serum Gly rose up significantly in both groups (P<0.01), and the between-group difference was statistically significant (P<0.05). After 1-month treatment, the CSS score dropped significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01);the ADL score increased significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01);the levels of serum GABA and Gly increased markedly in both groups compared to that before treatment (P<0.01), and the inter-group differences were statistically significant (P<0.01). After 3-month treatment, the CSS score dropped significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01);the ADL score increased significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01); the levels of serum GABA and Gly increased markedly in both groups compared to that before treatment (P<0.05), approaching the normal levels, and the inter-group differences were statistically insignificant (P>0.05). Conclusion Needling the Eight Confluent Points plus Huo Xue Rong Luo granules is effective in treating spastic paralysis after cerebral infarction, which is plausibly associated with the up-regulation of inhibitory neurotransmitters (GABA and Gly).
