Objective To assess the diagnostic value of bone scanning and bone alkaline phosphatase (B-ALP) detection in diagnosis of osseous metastases in lung cancer. Methods 58 patients with lung cancer were examined by bone scanning and serum alkaline phosphates(ALP) and B-ALP detection. The results were analyzed. Results Among the 58 patients, bone scanning found osseous metastases in 33 patients, the incidence was 56.90 %. Among the 58 patients, the incidence of bone metastasis of adenocarcinoma was 70.97 % (22/33) and squamous carcinoma was 42.86 % (9/21) (x2 =4.109, P =0.0427). The incidence of bone metastases increased in B-ALP ≥150 U/L. B-ALP was significantly correlated with the number of metastatic loci in bone. The sensitivity of bone scanning is the highest (93.94 %), but specificity the lowest (92.00 %).The sensitivity combining bone scanning and B-ALP is the lowest (57.58 %), but the specificity the highest (100.00 %). Conclusion Whole-body bone scanning has high sensitivity in early detection of bone metastases. For diagnosis of osseous metastases in patients with lung cancer, bone scanning is the primary choice. Combining the bone scanning with B-ALP can increase specificity. B-ALP has certain using value to confirm bone metastasis and decide the disease extent.

Objective To evaluate and summarize a new way of forward intensity modulated radia- tion therapy (IMRT) plan for nasopharyngeal carcinoma with 3Dmulti-leaf collimator (MLC) planning sys- tems is practised routinely in our department.Methods From September 2000 to July 2003 and November 2005 to March 2006,78 patients with nasopharyngeal carcinoma who were treated with eonformal radiothera- py used CT simulation for localizing,then doctors supervised the delineation of the planned tumor volume (PTV),gross tumor volume (GTV) and other sensitive organs on ACQsim workstation,and then sent the CT imagines to ELEKTA Precise Plan by DICOM RT Ethernet.Then,the physicists take over the responsibility of all directions of beam projection according to these organs and PTV shape,and completed the IMRT plan by manual correction making and the optimization of fields or segments shaped with forward 3D planning sys- tem.Results To analyse all the patient's dose distributions taking conformal radiotherapy in our hospital, we found the dose distribution and DVH data excellent,even better than the inverse planning of nasopharyn- geal carcinoma.Conclusions Intensity modulated radiation therapy (IMRT) is an advanced radiotherapy technique.A very good IMRT plan of nasopharyngeal carcinoma by forward planning can be obtained with 3D multiple leaf collimator (MLC) planning system.This planning method is more flexible,but the radia- tion physicists should be very much experienced in professional skill.

Objective To investigate the extraction method of total flavonoids from the leaves of ficus lacor and the protec tive effects of extraction on the cellular damage to provide a basis for the research on the phamaceutical value of ficus lacor leaves.Methods The ethanol extraction method was adopted to extract the total flavonoids in the leaves of ficus lacor and the extraction efficiency was calculated with rutin as the standard.The rotenone induced human lung adenocarcinoma cellular damage served as the model,then the influencesof the extraction on the cellular viability,cellular morphology,production of reactive oxygen species (ROS) and apoptosis were researched.Results The extraction efficiency of total flavonoids in the leaves of ficus lacor by 60％ ethanol was 5.02％;the extraction at the concentration of 32 mg/L could significantly inhibit the decrease of cell viability,cellular shape change,ROS production and apoptosis of A549 cells induced by 100μg/L rotenone.Conclusion The ethanol extraction method can be used to extract the total flavonoids in the leaves of ficus lacor and the extraction has the protective effects on the A549 cellular dam age induced by rotenone,the leaves of ficus lacor have the potential for further researching its pharmaceutical value.

At present, studies on traditional Chinese medicine (TCM) properties are mostly restricted to a single or two kinds of medicinal properties, but deviated from the holism of the theoretical system of TCMs. In this paper, the characteristics of pharmacological effects of different property combinations of TCMs distributing in the stomach meridian were take as the study objective. The data of properties of TCMs distributing in the stomach meridian was collected from the Pharmacopoeia of the People's Republic of China (2005). The data of pharmacological effects of TCMs distributing in the stomach meridian was collected from all of literatures recorded in Chinese Journal Full-text Database (CNKI) since 1980, Science of Chinese Materia Medica (Yan Zhenghua, People's Medical Publishing House, 2006) and Clinical Science of Chinese Materia Medica (Gao Xuemin, Zhong Gansheng, Hebei Science and Technology Publishing House, 2005). The corresponding pharmacological effects of property combinations of TCMs distributing in the stomach meridian was mined by the method of association rules. The results of the association rules were consistent with the empirical knowledge, and showed that different medicinal property combinations had respective pharmacological characteristics, including differences and similarities in pharmacological effects of different medicinal property combinations. Medicinal property combinations with identical four properties or five tastes showed similar pharmacological effects; whereas medicinal property combinations with different four properties or five tastes showed differentiated pharmacological effects. However, medicinal property combinations with different four properties or five tastes could also show similar pharmacological effects. In this study, the medicinal property theory and the pharmacological effects of TCMs were combined to reveal the main characteristics and regularity of pharmacological effects of TCMs distributing in the stomach meridian and provide a new way of thinking and method for revealing the mechanism action of TCMs distributing in the stomach meridian and discovering the pharmacological effects of TCMs distributing in the stomach meridian.

OBJECTIVETo compare the efficacy of different points combination in the treatment of menopausal insomnia.

METHODSNinety-six cases of menopausal insomnia were randomized into 3 groups, Xinshu (BL 15), Shenshu (BL 23), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6) were chosen in the restore interaction between the heart and the kidney group (group A, 32 cases); Zhaohai (KI 6), Jiaoxin (KI 8), Shenmai (BL 62), Pucan (BL 61) were chosen in the acupuncturing qiao mai group (group B, 32 cases); auricular Shenmen (TF4) and sensitive spot at the distribution area of auricular vagus nervus were chosen in the ear acupuncture group (group C, 32 cases). Six days made one session and the treatments were finished after 4 courses. The polysomnography (PSG) and Pittsburgh sleep quality index (PSQI) were employed before and after treatment to evaluate the alleviation of insomnia.

RESULTSThe parameters of the sleep latency (SL), rapid wave sleep latency (RL) and sleep efficiency (SE) were significantly improved in the three groups, and the differences were statistically significant (P < 0.05, P < 0.01). The SL and awaking time (AT) in group C [SL (401.08 +/- 16.54) min and AT (4.87 +/- 2.64) times] were significantly superior to those in the other two groups [SL (50.36 +/- 18.47) min, (54.87 +/- 20.92) min, AT (5.98 +/- 2.11) times, (6.13 +/- 3.04) times, all P < 0.05]. The S(3+4) (%) in group C was also significantly higher than those in the other two groups (both P < 0.05). It was indicated by PSQI that the sleep quality of group C (0.78 +/- 0.12) was significantly superior to that in group B (1.32 +/- 0.29), the total score and cured and markedly effective rate in group C [(4.34 +/- 1.43), 68.8% (22/32)] were superior to those in group A [(7.48 +/- 3.09), 53.1% (17/32), both P < 0.05].

CONCLUSIONEar acupuncture has a better curative effect than the restore interaction between the heart and the kidney group and acupuncturing qiao mai group, it is worth of being promoted.

OBJECTIVETo diagnose and detect the molecular defect in a suspected patient with Prader-Willi syndrome.

METHODSGenetic diagnosis and molecular genetic analysis were performed by using chromosome karyotype analysis, methylation-specific PCR (MS-PCR), and linkage analysis using short tandem repeat (STR).

RESULTSThe karyotype of the patient was 45, XX, der(5), t(5;15)(q35;q13), -15, and the parents were 46, XY and 46, XX, respectively, implying that the unbalanced translocation t(5;15) in the patient was de novo. Furthermore, MS-PCR and STR linkage analysis confirmed that the patient's 15q11-13 deletion was resulted from unbalanced translocation on paternal chromosome 15.

CONCLUSIONGenetic analysis should be applied in suspected patients with Prader-Willi syndrome to confirm the diagnosis. Cytogenetic and molecular techniques would be helpful in clinical diagnosis, genetic counseling and prenatal diagnosis.
