OBJECTIVETo discuss the TCM pattern classification and measurable diagnosis criterion of the protracted symptoms of heroin-addiction abstinence (PSHAA).

METHODSThrough literature review and clinical study, the concept of TCM patterns and diagnostic standard were established, and a TCM pattern scale for quantitatively analysis of PSHAA was formulated. The scale were used on the clinical investigation on the abuser for 5 times on day 15, 30, 60, 90 and 120 after abstinence. Then the TCM patterns of PSHAA was classified using methods of DME and quantitative diagnosis, to create a corresponding scale of diagnostic indexes referring maximum likelihood method.

RESULTS(1) The TCM patterns of PSHAA commonly seen were Toxin-stasis accumulation (TSA) with Qi-blood insufficiency, TSA with Qi-yin deficiency, TSA with Yin-deficiency and Fire-excess and TSA with Yin-Yang deficiency. (2) The retrospective and prospective verification of the scale of diagnostic indexes showed it has high sensitivity and speciality, with low rates of misdiagnosis and of missed diagnosis.

CONCLUSIONIt is feasible to develop measurable diagnosis on the TCM patterns of PASAA using DME method and measurable diagnostic methods. The scale of diagnostic indexes formulated with the maximum likelihood method of quantified diagnosis has a certain clinical practicability.

OBJECTIVETo observe the effects of Ganoderma lucidum spores on Cytochrome C (Cyt-C) and mitochondrial calcium in the testis of NIDDM rats.

METHODSFifty male Wistar rats were divided randomly into three groups: model, ganoderma and normal control, the first two groups injected with 2% STZ through vena caudalis, and the last one with half-and-half sodium citrate/citrate buffer solution. Two weeks after normal diet, glucose tolerance tests were performed and the rats with abnormal glucose tolerance from the model and ganoderma groups received high-fat and high-carbohydrate food, the ganoderma group given Ganoderma lucidum spores (250mg/[ kg x d] ) in addition, both for 10 weeks. Glucose tolerance tests were repeated 1 day before the end of the experiment and the rats were castrated and relevant indexes measured.

RESULTSThe NIDDM model was successfully constructed. In the model group, the levels of mitochondrial Cyt-C and mitochondrial calcium were significantly lower (P <0. 05) while that of the plasma Cyt-C was significantly higher than in the ganoderma and the control groups.

CONCLUSIONCyt-C and calcium ion are involved in the damage of the testis. Ganoderma lucidum spores can protect the testis of NIDDM rats.

OBJECTIVETo compare the differences in the efficacy on distant version of naked eye in the patients of juvenile myopia between rotating manipulation and lifting-thrusting manipulation of acupuncture.

METHODSOne hundred and twenty cases (240 eyes) were randomized into a rotating manipulation group and a lifting-thrusting manipulation group, 60 cases (120 eyes) in each group. Additionally, a corrective lenses group, 60 cases (120 eyes), was set up as the control. In both manipulation groups, Cuanzhu (BL 2),Yuyao (EX-HN 4), Sizhukong (TE 23), Taiyang (EX-HN 5), Fengchi (GB 20), Zusanli (ST 36), Guangming (GB 37) and Sanyinjiao (SP 6) were punctured, but stimulated with rotating manipulation and lifting-thrusting manipulation respectively three times per week, 10 times as a treatment session and totally one session was required. In the corrective lenses group, the glasses were applied at daytime. The clinical efficacy and the changes in distant vision of naked eye before and after treatment were compared among the three groups.

RESULTSThe total effective rate was 87.5% (105/120) in the rotating manipulation group, which was better than 69.2% (83/120) in the lifting-thrusting manipulation group (P < 0.05). The distant vision of naked eye was improved apparently in the rotating manipulation group and the lifting-thrusting manipulation group after treatment (both P < 0.05). But it was not improved in the corrective lenses group (P > 0.05). The distant vision of naked eye was improved more apparently after treatment in the rotating manipulation group as compared with that in the lifting-thrusting manipulation group (0.75 +/- 0.23 vs 0.68 +/- 0.24, P < 0.05). For 96 cases (192 eyes) with acupuncture treatment, in 3-month follow-up, 87.0% (167/192) of the cases maintained the stable vision as the original level and 13.0% (25/192) of them were reduced in the vision In the acupuncture groups, it was found that the improvement of distant vision of naked eye was more obvious after treatment with younger age, better basic vision and shorter duration of sickness (all P < 0.05).

CONCLUSIONAcupuncture achieves the positive and sustainable clinical effect on juvenile myopia, and the results of rotating manipulation are superior to that of lifting-thrusting manipulation. Age, basic vision and duration of sickness impact the clinical efficacy.

Objective To compare the diagnostic value 18F-fluorothymidine (FLT) and 18F-fluorodeoxyglucose (FDG) PET/CT in detecting lymph node metastases of untreated thoracic esophageal carcinoma. Methods Twenty-two patients with thoracic esophageal squamous cell carcinoma underwent both 18F-FLT and 18F-FDG PET/CT before surgery. The imaging results of the two modalities in detecting regional lymph node metastases were compared prospectively with the pathologic findings. The X2-test was used with SPS S 13.0. Results All patients underwent esophagectomy and lymphadenectomy. The metastatic lymph nodes were found in 16 patients, from which 47 of 424 excised nodes were positive by pathologic examination. False positive results were 14 while false negative 8 on 18F-FDG PET/CT. In contrast, false positive results were only 3 but false negative were 12 on 18 F-FLT PET/CT. The sensitivity, specificity, accuracy,negative predictive value, and positive predictive value were 74.47% ( 35/47 ), 99.20% ( 374/377 ),96.46% (409/424), 96.89% ( 374/386 ) and 92.11% ( 35/38 ) respectively for 18 F-FLT PET/CT, whereas the corresponding values were 82.98% (39/47), 96.29% (363/377), 94.81% (402/424), 97.84%(363/371 ) and 73.58% (39/53) respectively for 18 F-FDG PET/CT (X2 = 0.572, 6.018, 1.017, 0.348,3.852, P＞0. 05, ＜0.05, ＞0.05, ＞0.05 and ＞0.05). Conclusions Compared with 18F-FDG PET/CT, 18F-FLT PET/CT may be less sensitive but more specific for the detection of lymph node metastases of thoracic esophageal carcinoma.

BACKGROUND AND OBJECTIVEThe brain is one of the most common metastatic sites of breast cancer. Brain metastases develop in 10%-15% of patients with breast cancer and are associated with poor prognosis. The purpose of this retrospective study was to analyze the clinical characteristics and survival of patients with brain metastases due to breast cancer of different subtypes and to identify the prognostic factors that affect clinical outcome.

METHODSA total of 89 patients with breast cancer brain metastases diagnosed between October 1997 and July 2008 at Sun Yat-sen University Cancer Center were included in this study. Among the 89 patients, the number of luminal A, luminal B, human epidermal growth factor receptor 2 (HER-2), and triple-negative (TN) subtypes were 30, 20, 16, and 14, respectively; 9 patients had an unknown subtype. The clinical characteristics, pathologic features, and prognostic factors were analyzed both at the initial diagnosis and at the diagnosis of brain metastases. Endocrine therapy for patients with luminal subtypes was further studied.

RESULTSThe median age of patients was 46 years (range 28-74 years). The median survival time was 8.0 months (range, 0-80 months), the 1-year survival rate was 32% and the 5-year survival rate was 4%. The time to brain metastasis differed according to clinical stage at the initial diagnosis, and the time for patients with the luminal A subtype was the longest (P < 0.001). Multivariate analysis demonstrated that performance status score > 1, multiple brain metastases and without whole brain radiotherapy (WBRT) in combination with chemotherapy were associated with poor prognosis. Compared with the luminal A subtype, features of the HER-2 and TN subtypes included early metastases, rapid progression after first-line treatment (8.0 months vs. 11.0 months), and poor overall survival (25.0 months vs. 63.0 months). The luminal A subtype showed a tendency for good prognosis and slow growth. Tamoxifen could improve the survival of luminal A/B subtypes (median survival 24.0 months vs. 7.0 months, respectively, P = 0.002).

CONCLUSIONSThe prognosis of brain metastases from breast cancer was poor, especially in patients with HER-2 and TN subtypes. Generally, WBRT in combination with chemotherapy was the standard treatment modality. Patients with the luminal subtypes could benefit from tamoxifen.
