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 different needling depths for knee osteoarthritis(KOA)and the effects on effusion,cartilage thickness,and synovium under ultrasound imaging. Methods:A total of 90 patients with KOA were randomly divided into a conventional acupuncture group,a Western medication group,and a shallow acupuncture group,with 30 cases in each group.In the conventional acupuncture group,the needling depth was 15-30 mm,and the needle was twisted for a few moments after insertion so that a sore,numb,distending,and electrified sensation was obtained;in the shallow acupuncture group,the points were punctured perpendicularly by 2 mm,and no manipulation was performed after insertion.The same points were used in the two acupuncture groups,and the needles were retained for 20 min.The treatment was performed 3 times a week.The Western medication group was given glucosamine sulfate capsules for oral administration,2 capsules once,3 times a day.All three groups were treated for 8 weeks.The Western Ontario and McMaster Universities osteoarthritis index(WOMAC)and the visual analog scale(VAS)were scored before treatment,after 4 weeks and 8-week treatment,respectively;while the changes in knee cartilage,synovial membrane,and joint fluid were observed by knee ultrasound before and after 8-week treatment.The clinical efficacy was evaluated after 8-week treatment. Results:After 8-week treatment,the effusion and the synovial thickness improved significantly in both the conventional and shallow acupuncture groups compared with that before treatment(P<0.01);the effusion improved in the Western medication group compared with that before treatment(P<0.05);the synovial thickness improved better in the conventional acupuncture group than in the Western medication group(P<0.05).There was no statistically significant difference in the cartilage thickness among the three groups compared with that before treatment(P>0.05).The WOMAC(pain,stiffness,and function)and VAS scores decreased in all three groups after 4-and 8-week treatment compared with those before treatment(P<0.05).After 4-and 8-week treatment,the pain scores in WOMAC of the conventional acupuncture group were lower than those of the Western medication group and the shallow acupuncture group(P<0.05),and the VAS scores of the conventional acupuncture group were lower than those of the shallow acupuncture group(P<0.05).After 8-week treatment,the stiffness and functional scores in WOMAC of the conventional acupuncture group were lower than those of the Western medication group(P<0.05). Conclusion:Conventional acupuncture,oral Western medication,and shallow acupuncture all relieved knee pain and improved knee stiffness and functional movement.Among them,conventional acupuncture had the best efficacy in relieving knee pain and the best efficacy in improving joint function after 8-week treatment.Both conventional acupuncture and shallow acupuncture significantly reduced synovial thickness lesions in the knee;all three groups improved joint effusion and were more effective with conventional and shallow acupuncture.

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.

Objective To study the current situation of emergency nurses' structural empowerment,competency,job satisfaction,and their correlative factors.Methods Literature review, interview and questionnaire were used to establish the emergency nurses' structural empowerment and competency model.300emergency nurses were structurally empowered,and their quality of care and job satisfaction was compared before and after.Results The quality of care and job satisfaction after structural empowerment was (98.45 ±1.36) and (98.19 ± 2.63 ),both of which were higher than that before structural empowerment (95.33 ±2.47) and (93.81 ± 4.54),and the differences were statistically significant (t =-4.468,16.136,respectively; P ＜ 0.05).After structural empowerment,there was great improvement in emergency nurses' selfevaluation,as well as their ability of critical thinking,receiving information,communication and health education,while there was little improvement in their ability of social support,logical reasoning and innovation.Conclusions Establishing structural empowerment and competency model for emergency nurses helps them position themselves and promote their development,as well as provides reference to select and train professional nurses for hospitals.

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.
