Hereditary erythrocyte glucosephosphate isomerase (GPI) deficiency is thefourth most common cause of non-spherocytic hemolytic anemia. A case of GPI deficiencywas confirmed after screening a panel of 18 red cell enzymes and GSH. The GPI variantwas characterized by biochemical parameters including GPI activity in erythrocytes andplasma, low substrate activity, electrophoretic mobility, pH optimum, Michaelis constant(Km), thermostability, and substrate analogue (GAL-6-P) utilization rate. A new GPIvariant was found and was designated as GPI-Guangzhou.

Inspection of the complexion is one of the characteristics of traditional Chinese medical diagnosis. Traditional Chinese medicine puts high emphasis on inspection of the complexion and there exists detailed discussion on inspection of facial expression in Neijing. The so-called inspection of facial expression is a method to diagnose diseases according to the theory of five Zang-organs matching five elements and five colors by distinguishing various changes of facial color, such as green, red, yellow, white and black based on yin and yang doctrine and five elements theory. Nowadays, more and more experts have introduced color optical theory and modern devices into the modern research field of traditional Chinese medical diagnosis with the development of color optical theory and the renewal of determining devices, such as digital camera, color differentiation meter and spectrophotometer, to make the research more scientific and objective and avoid the deviations caused by human factors. The modern study of traditional Chinese medicine diagnosis has made fare progress, consequently enriching the contents of its facial color observation and giving a more scientific explanation of it. However, the devices being used now are still disunited; the data may be unilateral and cannot contain the whole information. So the most important task is to invent and use scientific devices conforming better with the theory of five colors observation in traditional Chinese medicine.

OBJECTIVE: To observe the correlation between serum level of TXB2, 6-Keto-PGF1alpha and liver metastasis. METHODS: The metastatic model was made by injection of W256 carcinosarcoma. Rats were randomly divided into two groups: rats with blood stasis group and control group. Rats in control group were given normal saline via abdominal cavity once a day. Rats in blood stasis group were injected adrenalin in the fourteenth day. Tumor size and liver metastasis were observed. Serum TXB2 and 6-Keto-PGF1alpha were tested by radioimmunoassay. RESULTS: Tumor size in rats with blood stasis was significantly smaller than that of the control group (P<0.01). Occurrence of liver metastasis in rats with blood stasis was significantly lower than that of the control group (P<0.01). The values of 6-Keto-PGF1alpha, TXB2, and TXB2/6-Keto-PGF1alpha were higher in the group with blood stasis. CONCLUSION: In the status of blood stasis, W256 carcinosarcoma grows slowly, and liver metastasis increases insignificantly, with the elevations of 6-Keto-PGF1alpha, TXB2 and TXB2/6-Keto-PGF1alpha.

Objective To develop a rapid method based on ARMS, named four primers allele-specific PCR(4p-AS PCR), to detect the most common non-deletional ?-thalassemia mutation Hb Constant Spring(Hb CS) by PCR technique. Methods The 4p-ASPCR was used to detect the Hb CS mutation of ?-thalassemia in 38 DNA samples of Hb H disease patients and using PCR-RE and DNA sequencing to confirm the results. Results Among the 38 Hb H disease patients 15 cases was revealed to carry Hb CS, 16 cases were deletional Hb H, and 7 cases need to be defined.Conclusion A simple, rapid and reliable method, named 4P-ASPCR, to detect Hb CS mutation have been developed. It is also may be useful in screen other point mutations such as Hb Quong Sze.

To select appropriate descriptors for response of the patient-reported outcome (PRO) scale for the main symptoms of patients with chronic obstructive pulmonary disease (COPD) complicated with pulmonary heart disease.

AIM: To observe the changes in tumor-weight-inhibiting rates,immunological function,liver and renal function and the blood cell in the peripheral blood after administration of Shengmai Injection combined with chemotherapeutic agent,Oxaliplatin. METHODS: Hepatoma 22 tumor bearing mice models were established and then divided randomly into five groups,including control group,Oxaliplatin group,Shengmai Injection(high,middle and low dose) combined with Oxaliplatin groups.Each group had 10 mice.The five groups were injected introperitoneally with same amount of 5% glucose injection,Oxaliplatin 6 mg/kg and Shengmai Injection(14 mL/kg,7 mL/kg and 3.5 mL/kg) plus Oxaliplatin 6 mg/kg respectively,once a day for 14 days. After that,mice in the five groups were all killed after being anesthetized and the tumor-weight-inhibiting rates and the index of immunological function,liver and renal function and the blood cell in the peripheral blood were observed. RESULTS: (1) The tumor-weight-inhibiting rates were higher in each Shengmai Injection plus Oxaliplatin group than that in the Oxaliplatin group (P

The methods of morphometry,histologic fluorescence quantification and quantita-tive histochemistry,RNA content,lipofuscin (Lp) content,nucleolar volume andneuron number (cells/250?m) were applied in the study of neurons in hippocampalCA_3 area in 4 age groups of Wistar rats (1,3,17,30 months).RNA content,nucleolar volume and neuron number decrease with advancingage.The difference between adult (17 months) and aged (30 months) rats weresignificant (P

The surface structure of the pineal recess in rat (Sprague-Dawley) was observedby using scanning electron microscope.Because of the distribution ofthe cilia and microvilli shows a regular changes from peripheralarea to central area in the recess,the surface of the recess can be divided intoperipheral,transitional and central zone.In the peripheral zone,there aresupraependymal cells in different appearance among those tufted cilia.Thetransitional zone is between peripheral and central zone.The cilia in this zone arefewer than those of the peripheral zone.We have observed the neuron-like suprae-pendymal cell with a splndle shaped cell body and numerous small holes as well assupraependymal nerve fibers in the floor of this zone.The ending of the nerve fiberis varicose.Some smooth areas devoid of cilia and microvilli were presentin the central zone.There are also neuron like cells with slender processes,roundsupraependymal cell,some fine crisscrossing fibers and some sprouted cilia.Acluster of bleb-like structures are present in this zone.The relations between thesurface of the recess and the pineal gland are discussed.

To observe the effects of Shengmai Injection on enhancing efficacy and reducing toxicity of 5-fluorouracil (5-FU).

Smoothened (SMO) is a member of sonic hedgehog homology (SHH) signaling pathway. It plays a key role as a bridge between patched-1 (PTCH-1) and Gli. Aberrant SHH expression can be detected in various malignant tissues, and the expression in pancreatic cancer stem cells is higher apparently. SHH signals are closely associated with self-duplication of cancer stem cells, formation of tumor vessels as well as matrixes. SMO antagonists such as cyclopamine, GDC-0449 and so on show potential to inhibit activity of SHH signaling, and arrest the growth as well as metastases of tumors. Recently, a few of SMO antagonists have been studied in phase I clinical trials and some are in phase II, meanwhile, phase I or II trials of SMO antagonists to treat pancreatic cancer are performed currently. As the classical SMO antagonist, cyclopamine is extracted from a medicinal plant. Perhaps researchers may be able to determine more effective SMO-targeting drugs from herbal medicines in the future.
