Objective To evaluate if the assay of platelet-associated immunoglobulin G (PAIgG) can improve the sensitivity of monoclonal antibody immobilization of platelet antigens assay (MAIPA) in immune thrombocytopenic purpura (ITP).Methods Anti-GP Ⅱb/Ⅲa and anti-GP Ⅰb/Ⅸ autoantibodies were detected by a modified MAIPA;PAIgG was detected by competitive ELISA.MAIPA and PAIgG were done simultaneously in 190 patients with thrombocytopenia,in which 132 were diagnosed as ITP according to the diagnostic criteria Kappa test was used to analyze the concordance between MAIPA and PAIgG.Results The sensitivities of PAIgG alone or in parallel with MAIPA to ITP were 32.6% and 37.2% higher than MAIPA alone respectively,while their specifieities were 51.7% and 56.9% lower respectively.The sensitivity,specificity,positive predictive value,negative predictive value of PAIgG in series with MAIPA were all not superior to MAIPA alone.The kappa values between MAIPA and PAIgG in ITP and non-immune thrombocytopenia were 0.129 and 0.012 respectively,which meant the concordance between them was poor.Conclusion The detection of PAIgG should not be used as screening before MAIPA in distinguishing immune from non-immune thrombocytopenia.

Objective To summarize the experience of nursing the patients with liver transplantation complicated with early portal vein thrombosis treated with post-embolectomic anticoagulation. Method The clinical data of 5 cases of liver transplantation-induced portal vein thrombosis treated with post-embolectomic anticoagulation was reviewed to summarize the curative effect , key points for disease conditions and anticoagulative nursing. Results The anticoagulative effect was not good in only one case. 4 other cases were recovered by embolectomy and postoperative anticoagulation therapy as well as related nursing measures. Conclusion The nursing measures such as close observation of the disease processing, early reasonable anticoagulation, accurate medication, prevention of patent complication are critical for preventing the recurrence of portal vein thrombosis after liver transplantation.

Bacterial biodiversities of microbial mat and sediments, which were sampled from thermal springs of Tengchong Rehai in Yunnan, were preliminarily studied with PCR-denaturing gradient gel electrophoresis (PCR-DGGE). Directly extracted total DNA from environmental samples amplified by PCR with two sets of bacteria-specific primers. The PCR products, which include the V 8 and V 9 high-variable regions respectively, were analyzed by using DGGE. The DGGE profiles not only indicated the existence of higher levels of bacterial diversity, but also showed that the microbial mat and sediments have different dominant bacteria. Furthermore, the bacterial PCR-DGGE displayed clear profiles of bacterial structure selected by the key abiotic factors of the extreme environments, such as temperature and concentration of oxygen.

Objective: To observe the efficacy of long-retaining scalp acupuncture plus interactive training in improving upper- extremity dysfunction in cerebral stroke patients. Methods: Ninety-five patients with upper-extremity dysfunction after cerebral stroke were randomized into two groups, with 48 cases in the treatment group and 47 cases in the control group. Conventional internal medicine treatment was offered to both groups. In both groups, Anterior Oblique Line of Vertex-temporal (MS 6, the middle 2/5) and Posterior Oblique Line of Vertex-temporal (MS 7, the middle 2/5) were selected from the same side of the brain lesion (the side apposing to the hemiplegic limb) for scalp acupuncture treatment. In the treatment group, the scalp acupuncture needles were retained for 7 h, in combination with interactive training, while the needles were also retained for 7 h in the control group but without interactive training. Prior to treatment and at 2-week and 4-week treatment, the two groups were scored using the functional test for the hemiplegic upper extremity-Hong Kong (FTHUE-HK) and simplified Fugl-Meyer assessment-upper extremity (FMA-UE). Results: The total effective rate was 97.9％ in the treatment group, higher than 74.5％ in the control group (P<0.01). The FTHUE-HK score was higher at 2-week and 4-week treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FTHUE-HK score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FTHUE-HK score was higher in the treatment group than in the control group, showing significant between-group differences (both P<0.05). During the whole treatment process, the treatment group had higher FTHUE-HK scores compared with the control group, but there was no statistical significance comparing the change of the score between the two groups at 2-week treatment (P>0.05), while the between-group difference in the change of the score was statistically significant at 4-week treatment (P<0.05). The FMA-UE score was higher at 2-week and 4-weeks treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FMA-UE score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FMA-UE was higher in the treatment group than in the control group, and the between-group differences were statistically significant (both P<0.01). The FMA-UE score rose gradually with the increase of treatment session, and there was statistical significance comparing the change of the score between the two groups at 2-week and 4-week treatment, respectively (both P<0.05). Conclusion: Long-retaining scalp acupuncture plus interactive training results in more significant efficacy than long-retaining scalp acupuncture alone in improving the upper-limb dysfunction after cerebral stroke and the advantage becomes more notable after 2-week consecutive treatment.

Objective To investigate the expression and clinical value of immunohistochemistry in endometrial stromal tumors.Methods Immunohistochemical technique(Envision method)was applied to de- tect the expression of CD_(10),SM-MHC,h-caldesmon,AE1/3,CD_(99),Ki-67,CD_(34),c-kit,ER and PR in 15 cases of endomertrial stromal sarcoma and 3 metastases.The clinical pathological data,including the histological characteristics,histochemical and immunohistochemical staining features,complication,differential diagnosis and prognosis of endometrial stromal tumours were analyzed.Results Among the 18 cases of endometrial stromal tumor,17 cases had shown positive for CD_(10),including 13 cases diffuse positive and 4 muitifocal,7 cases with smooth muscle differentiation,3 cases with epithelial differentiation,7 cases with sex-cord differ- entiation.13 cases of ER and 16 cases of PR were positive expression in endometrial stromal sarcoma.Ki-67 in range 36 %～78 %.Conclusion Endometrial stromal tumour can display multi-differentiation.They show various pathomorphological features,Smooth muscle and sex-coed differentiation,the most common types. CD_(10) can be expressed consistently in endometrial stromal tumors.CD_(10) with h-caldesmon and SM-MHC can be used to make differential diagnosis between the endometrial stromal tumors and cellular leiomy0ma.ER and PR should be routinely estimated and be a prognostic predictor for endometrial stromal sarcoma.

During the routine impurity profile of lisinopril bulk drug by HPLC (high-performance liquid chromatography), a potential impurity was detected. Using multidimensional NMR (nuclear magnetic resonance) technique, the trace-level impurity was unambiguously identified to be 2-(-2-oxo-azocan-3-ylamino)-4-phenyl-butyric acid after isolation from lisinopril bulk drug by semi-preparative HPLC. Formation of the impurity was also discussed. To our knowledge, this is a novel impurity and not reported elsewhere.

In order to understand whether some special amino acids in the medial vestibular nucleus (MVN) of rats are involved in the regulation of blood pressure, we used microdialysis technique and high performance liquid chromatography (HPLC) to measure the changes of glutamate and taurine in this central area. Acute hypotension was induced by hemorrhage from the femoral artery. It was observed that the basal release of glutamate and taurine in the MVN was stable about 90 min after the beginning of microdialysis. The basal release of glutamate was (18.96 +/- 0.27) pmol/sample (8 mul), and that of taurine was (7.73 +/- 0.05) pmol/sample (8 mul). Glutamate release increased (P<0.05) and taurine release reduced (P<0.05) in the MVN in the hemorrhage-induced acute hypotensive rats. Nevertheless, these changes were not observed in the hemorrhage-induced acute hypotensive rats which were pretreated by infusing 2% lidocaine into the middle ear or 100 mg arsanilic acid into the tympanic cavity. These results suggest that the hemorrhage-induced acute hypotention can influence the activity of the neurons in the MVN by the afferent impulses from vestibular organ, and that some special amino acid transmitters in the MVN are involved in this process.

Temperature plays an important role in pyruvate biosynthesis by Torulopsis glabrata 620. The effects of temperature on the substrate consumption, cell growth, pyruvate biosynthesis and level of energy charge and oxidation-reduction state have been investigated. During the constant temperature fermentation, higher temperature can enhance the rate of glucose consumption, cell growth and pyruvate production. However, it also leads to higher energy charge in the prophase of fermentation, too much consumption of glucose by cell and deficient throughput of pyruvate in the anaphase of fermentation, which brings on decrease of pyruvate yield. Oppositely, maintaining lower temperature during the fermentation can offer constant production capacity of pyruvate in the anaphase of fermentation. But the disadvantages are lower cell growth and higher level of NADH/NAD+ in vivo during the anaphase of fermentation, which leads to lower productivity inevitably. Disaccords above-mentioned indicate that the higher production, higher yield and higher productivity cannot be achieved at one time during a constant temperature fermentation.
