Objective To explore the TCM syndrome characteristics of cardiac syndrome X(CSX).Methods The signs and symptoms of 51 patients with CSX were analyzed according to the diagnosis of TCM syndromes to summarize their syndrome character- istics.Results of the 51 CSX cases,the following signs and symptoms took dominance:chest pain,fullness in chest,epigastric and abdominal distention,emotional distress,dark purple tongue with petechia,greasy coating,string-taut pulse.The syndromes were mainly of Biao-Superficial excess,including qi stagnation,phlegm retention and blood stasis,occupying 66. 7%,accompanied with Benroot deficiency,including qi deficiency,yin deficiency,qi and yin both deficiency,occupying 33.3%.Conclusion Qi stagnation, phlegm retention and blood stasis are the primary syndromes of CSX.

OBJECTIVETo carry out expert survey for traditional Chinese medicine (TCM) syndrome characteristics of different clinical types of coronary artery disease (CAD).

METHODSBy using Delphi method, we carried out two rounds of nationwide expert surveys for modern TCM characteristics of syndrome elements and syndrome types of CAD.

RESULTSBased on expert consensus, qi deficiency, blood stasis, phlegm turbidity, qi deficiency blood stasis, and intermingled phlegm and blood stasis are common TCM syndromes for different clinical types of CAD. Of them, qi stagnation, blood stasis, phlegm turbidity, heat accumulation, cold coagulation, yang deficiency, deficiency of both qi and yang were more often seen in patients with unstable angina than in those with stable angina. Qi deficiency, yin deficiency, and deficiency of both qi and yin were less seen. We could see more excess syndrome and less deficiency syndrome (such as qi deficiency, yin deficiency, etc.) in acute ST-segment elevation myocardial infarction (STEMI) than acute non-ST-segment elevation myocardial infarction (NSTEMI). Qi deficiency, blood stasis, water retention, yang deficiency, phlegm turbidity, yin deficiency, Xin-qi deficiency, and qi deficiency blood stasis induced water retention are the most common TCM syndrome types of CAD heart failure (HF). Blood deficiency, yin deficiency, heat accumulation, deficiency of both Xin and Pi, deficiency of both qi and blood, deficiency of both qi and yin, yin deficiency and fire hyperactivity were more often seen in CAD arrhythmias.

CONCLUSIONSTCM syndrome distributions of different clinical types of CAD have common laws and individual characteristics. Results based on the expert consensus supplied evidence and support for clinical diagnosis and treatment of CAD.

OBJECTIVETo investigate the monitoring and therapeutic methods of nonoperative management of blunt splenic injury.

METHODSEighty-two cases with nonoperative management of 95 patients of blunt splenic injury from September 2005 to April 2008 were analyzed retrospectively. Percutaneous peritoneal drainage was applied to 75 cases, and auto-blood transfusion was applied to 38 cases. Eighty-two cases were followed up from 3 weeks to 8 months.

RESULTSEighty-two patients with nonoperative management were treated successfully, including 34 cases classified as grade III to IV, 6 cases over 55-years-old, 14 cases with severe multiple injury (ISS > or = 16) and 37 cases whose drained peritoneal blood volume were over 500 ml. The drained peritoneal blood volume was 30 to 2400 ml. The total volume of auto-blood transfusion was 22 300 ml and the average volume was 613 ml. All cases were followed up without delayed hematocele or peritoneal infection.

CONCLUSIONSMost hemodynamically stable patients with blunt splenic injury can be healed with nonoperative management. The treatments including percutaneous peritoneal drainage and transfusion of auto-blood can significantly increase the performance rate and the achievement ratio of nonoperative management of blunt splenic injury.

OBJECTIVETo assess the correlation of O6-methylguanine-DNA methyltransferase (MGMT) to radiation sensitivity of nasopharyngeal carcinoma (NPC).

METHODSEighty randomly selected NPC patients were divided into high (+/++, n=62) and low (-/+/+, n=18) MGMT groups according to the results of MGMT detection using immunohistochemistry. All the patients received irradiation with external beam radiotherapy, and the radiation sensitivity of NPC was analyzed after the irradiation.

RESULTSThe rates of high and low radiation sensitivity were 83.3% and 16.7% in low MGMT group, respectively, showing significant differences from those of the high MGMT group (45.2% and 54.8%, respectively, chi(2)=4.393, P=0.036).

CONCLUSIONThe content of MGMT correlates to the radiation sensitivity of NPC and may serve as valuable indicators for predicting the radiation sensitivity of NPC.

Clinical reports on cardiac syndrome X (CSX) have been increasing in recent years. In general, CSX does not increase the cardiovascular mortality, but it can affect the patient's quality of life (QOL) and increase the incidence rates of cardiovascular and cerebrovascular events. Although a variety of drugs and therapies have been utilized in the clinical treatment, the management of CSX still represents a major challenge due to its unclear pathogenesis. It is necessary to explore more effective treatment programs. Many attempts have been made on trials of the Chinese medicine (CM) treatment for CSX and proved that CM has a certain advantage in efficacy to improve clinical symptoms and QOL. CM may provide a new approach for the effective treatment of CSX.

Abstract: Olfactory receptors (ORs) are transmembrane proteins mainly distributed in olfactory sensory neurons of the nasal epithelium, mediating the transmission of real-time sensory signals to the brain to produce smell. Recent studies have reported that ORs can also be expressed in tissues or organs outside the nasal cavity, and are closely related to a variety of biological processes, such as sperm chemotaxis, wound healing, glycolipid metabolism and intestinal secretion. In addition, ORs are closely related to a variety of malignant tumors such as prostate cancer, breast cancer and colorectal cancer, and may affect the occurrence and development of tumors by regulating cell proliferation, apoptosis, migration and invasion. This review provides an overview of the effects of ectopic ORs on the function of various human tissues and organs and assesses their potential value as drug targets for the treatment of human diseases.

OBJECTIVETo assess the spermatogenic function of the infertile patients with Y-chromosomal microdeletion.

METHODSThirty-five 23-44 years old patients with microdeletions of Y chromosome were included in this study. Three semen analyses confirmed that 26 cases were non-obstructive azoospermia and 9 oligospermia with sperm count < 1 x 10(6)/ml. They were divided into 3 groups by the locus of deletion, 5 cases of AZFa + b + c deletion in group 1, 4 cases of AZFb + c and 3 cases of AZFb deletion in group 2, and 23 cases of AZFc deletion in group 3. Semen was collected and centrifuged, the supernatant removed and the centrifugate applied on the clean slides after dilution. Following Wright's-Giemsa staining, the slides were viewed under the microscope. Testis histopathological biopsy was performed for 6 of the cases.

RESULTSIn group 1, no spermatogenic cells were observed but only Sertoli cells in 1 case, with a consistency between the result of spermatogenic cell test and that of testis biopsy. In group 2, spermatogenic cell tests revealed spermatocytes in 6 cases, 2 were proved by testis biopsy with sperm maturation arrest in the primary spermatocyte stage, and spermatogenic cells of all developmental stages were seen in 1 AZFb deletion patient with the same sperm maturation arrest as the above two. In group 3, only primary spermatocytes were detected by spermatogenic cell test in 5 oligospermia patients but no spermatogenic cells in the 15 azoospermia cases, and biopsy revealed 2 cases of Sertoli cell-only syndrome.

CONCLUSIONThe spermatogenic cell test can effectively assess the spermatogenic function of AZF deletion patients. Non-invasive and easily accepted by patients, it is highly recommendable for the evaluation of spermatogenesis of patients with Y-chromosomal microdeletion.

OBJECTIVETo investigate the expression and its clinical significance of estrogen receptor (ERα) and phosphorylated estrogen receptor (p-ERα) in patients with hepatocellular carcinoma. The associations between ERα, p-ERα and IL-6 were also analyzed.

METHODSImmunohistochemistry was used to detect the expression of ERα, p-ERα and IL-6 in tumor tissues from 77 cases with hepatocellular carcinoma. The relations between ERα and the clinical pathological parameters and prognosis were also analyzed.

RESULTSThe positive rates of ERα, p-ERα and IL-6 in hepatocellular carcinoma were 39.0% (30/77), 45.4% (35/77) and 72.7% (56/77), respectively. The expression of ERα and p-ERα were negatively correlated with the expression of IL-6 (r=-0.468, P<0.01; r=-0.370, P<0.01, respectively). The positive rate of ERα in patients with tumor size≤5 cm, serum level of alpha-fetoprotein<400 µg/L, with complete encapsulation and non-microvascular invasion was significantly higher than those with tumor size>5 cm, serum level of alpha-fetoprotein&ge;400 µg/L, non-complete encapsulation and with microvascular invasion (all P<0.05). The overall survival rates of ERα-positive and ERα-negative patients were 66.7% and 23.4% (P<0.05). And the disease-free survival rates of ERα-positive and ERα-negative patients were 83.3% and 57.4% (P<0.05).

CONCLUSIONSThe tumor biological features of ERα-positive patients are better than that of ERα-negative patients. The role of ERα in hepatocellular carcinoma may be related to IL-6 level.

The aim of the study is to evaluate the effects of the single and mixed decoction of Thallus laminariae (kelp) and Glycyrrhiza glabra (licorice) on the metabolism and their difference. The mixed decoction of kelp and licorice and the single decoction were made and intragastrically administered to the SD rats. The effect on system metabolism, the toxicity of liver and kidney were assessed by GC-MS profiling of the endogenous molecules in serum, routine biochemical assays and histographic inspection of tissues from SD rats, separately. The mixed decoction of kelp and licorice induced more obvious pathological abnormalities in SD rats than a single decoction of kelp, while the extracts of licorice did not show any pathological change. Neither the mixed, nor the single decoction showed abnormal histopathology. After intragastric administration of extracts for 5 days, the mixed decoction induced a decrease of ALT (no significant change in the groups of single decoction) and an increase of BUN (so did the single decoction of kelp). Metabolomic profile of the molecules in serum revealed that the metabolic patterns were all obviously affected for the three groups, i.e., the mixed and single decoction of kelp and licorice. The rats given with the single decoction of kelp showed a similar pattern to that of the mixed decoction, indicating that the kelp primarily contributed the perturbation of metabolism for the mixed decoction. All three groups induced a decrease of branched chain amino acids, TCA cycle intermediates and glycolysis intermediates (e.g., pyruvic acid and lactic acid) and an increase of 3-hydroxybutyric acid. Kelp decoction showed stronger potential in reducing TCA cycle intermediates and glycolysis intermediates than the other two groups, while the levels of branched chain amino acids were the lowest after licorice extracts were given. These results suggested that the effect of the mixed decoction on metabolism was closely associated with both kelp and licorice. The continuous administration of single decoction of kelp and the mixed decoction of licorice and kelp resulted in pathological abnormalities in kidney of SD rats. The mixed decoction of kelp and licorice distinctly perturbed sera molecules and hence system metabolism, which showed associated with those of kelp and licorice. Although the metabolic effect was associated with both kelp and licorice, the results suggested kelp contributed to it primarily.
