(2) The results of single-factor variance analysis showed that the differences of symptoms scores before treatment, at the first and the last follow-up were statistically significant (P<0.01) . The symptoms scores before treatment, at the first follow-up and at the last follow-up were in decreasing sequence (P<0.01) . Conclusion Modified Xiaoshengliu Decoction shows certain effect on the intervention of sub-health population with the syndrome of Qi-yin deficiency .

ObjectiveTo review the clinical features,management and prognosis of renal Ewing's sarcoma (ES) of a single case report.MethodsA single case of renal ES was reported.A 33-year-old male presented with a mass in the left kidney found during a three day medical examination.B-ultrasound examination showed a lesion with rich blood flow signals and well defined margins in the inferior portion of the left kidney.The CT scan revealed a solid mass of 5.1 cm × 4.7 cm in the inferior portion of the kidney with un-even enhancement by contrast.A possible diagnosis of renal carcinoma was given prior to surgery.No metastasis was proven.A literature review of ES was then conducted.ResultsA left retroperitoneoscopic radical nephrectomy was successfully performed.Gross pathologic examination showed a solid tumor with necrosis,localized at the inferior pole of the left kidney.The histopathological examination revealed the tumor consisted of small round tumor cells,which were positive for CD99,vimentin and PAS,but negative for WT-1.A diagnosis of ES of the kidney was then determined.The patient received alternating short cycle ( CTX + VCR + THP) and long cycle ( IFO + VP-16) adjuvant chemotherapy for 6 cycles after the operation.There has been no evidence of recurrence at the 14-month follow up.ConclusionsES of the kidney is a rare disease with no specific clinical feature in most cases.Diagnosis of renal ES must be confirmed with histological features.Surgery combined with radiotherapy and chemotherapy is the main method of therapy for renal ES.The prognosis of renal ES is poor.

Objective To investigate clinical manifestations and clinical diagnosis and treatment and pathological and immunohistochemical features in gastrointestinal stromal tumors. Methods The clinical data of fifty-two cases with gastrointestinal stromal tumors were collected, whose clinical diagnosis and treat-ment and pathological features were retrospectively analyzed from January 1995 to December 2007. Results All patients received operation therapy, only forty-five cases with complete surgical resection. The immu-nohistochemical staining showed that the cases with CD117 positive accounted for 100% (52/52) and CD34 positive accounted for 88.5% (46/52). Conclusions Surgery was necessary for all patients, especially complete surgical resection. Gastrointestinal stromal tumors were poor in preoperative diagnosis, which diag-nosis was based on the immunohistochemical staining of the tumor tissue. CD117 and CD34 tumor markers may help to diagnose gastrointestinal stromal tumors.

OBJECTIVE: To establish the quality standard of Lithocarpus polystachys.METHODS: TLC was used for the qualitative identification of L.polystachys.The content of total flavonoids of L.polystachys was determined by UV spectrophotometry and the content of phloridzin was determined by HPLC.RESULTS: The TLC spots of polyamide were clear and well separated.The maximum absorption wavelength of phlorizin was 284 nm.The content of total flavonoids of 6 batches of L.polystachys ranged from 103.12 mg?g-1 to 183.54 mg?g-1.The linear ranges of phlorizin were 0.099 8～1.197 6 ?g (r=0.999 7) with an average recovery of 97.23%(RSD=1.57%,n=6).CONCLUSION: Established quality standard is applicable for the quality control of L.polystachys.

OBJECTIVETo study the content of mineral elements and the principal components in Gastrodia elata.

METHODMineral elements were determined by ICP and the data was analyzed by SPSS.

RESULTK element has the highest content-and the average content was 15.31 g x kg(-1). The average content of N element was 8.99 g x kg(-1), followed by K element. The coefficient of variation of K and N was small, but the Mn was the biggest with 51.39%. The highly significant positive correlation was found among N, P and K . Three principal components were selected by principal components analysis to evaluate the quality of G. elata. P, B, N, K, Cu, Mn, Fe and Mg were the characteristic elements of G. elata.

CONCLUSIONThe content of K and N elements was higher and relatively stable. The variation of Mn content was biggest. The quality of G. elata in Guizhou and Yunnan was better from the perspective of mineral elements.

AIM:To study the telomere maintenance mechanism in mesenchymal stem calls(MSCs).METHODS:MSCs were isolated from healthy human bone marrow by their adherence to plastic and then were checked with CD14-FITC,CD45-FITC,CD44-FITC,HLA-DR-FITC,CD34-PE,CD29-PE and CD166-PE.Telomere length and ECTR DNA in MSCs were detected by Southern blotting.The localization of TRF1 and promyelocytic leukemia(PML)in MSCs were detected with immunofluorescence staining.TRAP protocol was performed to detect the telomerase activity in MSCs and MSCs-derived adipocytes.Western blotting and TRAP protocol were applied to measure telomerase activity of MSCs,which were synchronized by serum starvation and aphidicolin treatment.RESULTS:The telomere in length seemed shorter and relatively more homogeneous in MSCs and HeLa cells than that in WI-38-2RA cells.TRF1 did not concide with PML nuclear body in MSCs and HeLa cells while it exclusively did in WI-38-2RA cells.ECTR DNA was negative in MSCs and HeLa cells but positive in WI-38-2RA cells.Telomerase was negative in MSCs but it was positive in MSCs-derived adipocytes detected by TRAP.Moreover,a cell cycle-dependent expression profile of telomerase was found in MSCs when they were synchronized by serum starvation and aphidicolin treatment.Untreated MSCs expressed very low level of telomerase probed by Western blotting with 2C4 mAb,but the telomerase level had significantly increased when these cells were trapped in S phase.CONCLUSION:The telomere of MSCs is maintained by telomerase pathway instead of alternative lengthing of telomere(ALT)and the level of telomerase expression is associated with cell cycle stage.[

Objective: To analyze the relationship between inflammatory factors and relevant risk factors in patients of essential hypertension (EH) combining acute coronary syndrome (ACS) with its clinical significance. Methods: Our research included 3 groups: EH group, n=79 patients with standard criteria, EH+ACS group, n=85 and Control group, n=48 normal subjects. Blood levels of lipoprotein-associated phospholipase A2 (Lp-PLA2), tryptase (TPS) and relevant clinical, biochemical parameters were measured; risk factors for cardiovascular disease were examined and the relationship between above parameters, risk factors and ACS occurrence in EH patients was studied by Logistic regression analysis. Results: The OR values were all greater than 1 in fibrinogen (Fbg), high-sensitivity C-reactive protein (hs-CRP), TPS, atherosclerotic plaque, Lp-PLA2 and EH grading. Fbg was the most significant independent risk factor (OR=22.242, 95% CI 6.458-76.609, P<0.0001), the standardized partial regression coefficient b'as absolute value (b') was 1.079 which was the highestone in above 6 variables with the strongest impact for ACS occurrence in EH patients. Conclusion: Fbg, hs-CRP, TPS, atherosclerotic plaque and EH grading were the independent risk factors for ACS occurrence in EH patients; Fbg was the highest risk factor for ACS occurrence with the strongest impact, which provided a new direction for ACS prevention and treatment.

OBJECTIVETo analyze the clinical characteristics and effects of rehabilitation treatment on hemophiliacs with iliopsoas hemorrage.

METHODSThe hemophilia patients with iliopsoas bleeding treated in Peking Union Medical College Hospital between January 2006 to December 2010 were enrolled. The clinical characteristics including symptoms, signs, complications, and rehabilitation treatment were analyzed retrospectively.

RESULTSAll of the forty-one hemophiliacs with iliopsoas bleeding were male, 20 cases wee the left bleeding, 18 the right, and 3 the bilateral. The median median age was 18 (6 - 61) years old(y). The median age of the iliopsoas bleeding for the first time was 17 (6 - 20) y. 34 patients accompanied with femoral nerve injury, 19 of them had secondary knee bleeding on the same side. 20 patents had quadriceps atrophy. Pelvic pseudotumor developed in 2 patients and permanent abnormal posture in 2 patients. The main finding of the ultrasound image was low-echo mass in iliopsoas muscles or inguinal region. 34 patients received rehabilitation therapy for 8 - 12 weeks under the support of factor replacement, complete hematomas absorption in 33 of them, with hip range of motion recovering back to baseline. 27 of 32 (84.4%) cases with femoral nerve injury got quadriceps strength above 4/5 grade, 20 cases of femoral nerve injury (62.5%) still had numbness on front of their thigh after treatment.

CONCLUSIONSIn this cohort of iliopsoas bleeding, most of the patients are adolescent. High prevalence of the femoral nerve injury and the secondary knee bleeding are found. Rehabilitation treatment under the support of factor replacement is safe and effective on hematoma absorption and neurological function recovery.
