Objective To observe the effect of Tongsai Xiaoshuan Decoction on the treatment of 30 stroke patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods 30 patients were treated with Tongsai Xiaoshuan Decoction. 28 patients treated regularly were served as controls. Both group were performed CT/MRI and Polysomnography examination before and after treatment. Their apnea and hypoventilation index were recorded. Results The efficiency of Tongsai Xiaoshuan Decoction was evident. The apnea and hypoventilation index were decreased, the medial hypopnoea time decreased, and the medial time for SaO2 less than 90% decreased. Comparing with the regular group, the difference was significant (P

Objective To investigate the clinical features with to highlight the main criteria for diagnosis of portopulmonary hypertension(POPH).Methods The clinical and laboratory data of 7 patients with POPH were retrospectively analysed.Results The patients included 2 males and 5 females with median age at diagnosis of 51 years(ranging from 26 to 73 years).The underlying diseases of portal hypertension were post-type B hepatitis cirrhosis(3 cases),autoimmune hepatitis(2 cases),immunologic deficiency disease(1 case)and portal vein thrombosis(1 case).The initial symptom of pulmonary hypertension(PH)in 5 patients was dyspnea on exertion,but 2 patients remain asymptomatic.All patients was assessed by transthoracic echocardiogram(TTE)with the pulmonary arterial systolic pressure(PASP)above 55 mmHg,1 patient accepted right heart catheterization(RHC)with mean pulmonary arterial pressure of 62 mmHg and pulmonary vascular resistance of 8.64 mN/(s?cm5).Immunologic abnormality was found in 6 patients,and the severity of liver function does not appear to correlate with the severity of the PH.Follow-up study demonstrated 3 patients died,2 of whom were due to the cardiac involvement(right heart failure and sudden death).Conclusion PH is a rare but severe complication of portal hypertension.It is the portal hypertension,not the underlying liver disease causing POPH.TTE is an important screening procedure,but the gold standard for diagnosis of POPH is hemodynamic data from RHC.

Objective:To culture canine dental pulp stem cells(cDPSCs)in vitro.Methods:Canine pulp cells were isolated and cultured by enzyme digestion and explanted tissue culture respectively.Cell morphology was observed under phase-contrast micro-scope.The clone forming unit(CFU)of the cells was examined by plate clone formation assay.Cell markers and protein-expression were examined by flow cytometry(FC)and immunofluorescence.Odontogenic and adipogenic potential were evaluated by alizarin red staining and oil red O staining.Results:Short spindle fibroblast-like and steadily growing cells were obtained by both methods.The clone assay showed that CFU was 1 5.1 7% ±2.79%.FC observasion showed that the CD90,STRO-1 and CD24 positive cells were 24.43% ±7.1 0%,20.67% ±1 .42% and 2.03% ±0.06% respectively,but CD34 was negative.Immunofluorescence analysis showed positive expression of Nestin,Vimentin,weak expression of ALP and negative expression of DSP of the cells.Differentiation ex-periment confirmed the odontogenic and adipogenic differentiation potential of the cells.Conclusion:cDPSCs can be cultured in vitro.

BACKGROUND:Ultrasound therapy can relieve pain and improve the movement function in patients with knee osteoarthritis, but there lacks of consistency in the literatures of ultrasound therapy.
OBJECTIVE:To further identify the effectiveness of ultrasound therapy in the treatment of knee osteoarthritis.
METHODS:Twenty-four rabbits were randomly divided into three groups:normal group, model group and ultrasound group. The rabbit in the normal group received no intervention;rabbits in the model group received anterior cruciate ligament transaction to establish the knee osteoarthritis model without any treatment;the rabbit in the ultrasound group received ultrasound therapy after modeling for 10 minutes once time, once per day, 0.3 W/cm2 , 1 MHz and treated for 10 times. Hematoxylin-eosin staining was conducted for histological observation of rabbit articular cartilage;western blot and reverse transcription PCR assessment were used to assess the expressions of caspases-3 and caspases-8 in rabbit articular cartilage, while Terminal deoxynucleotidyl transferase dUTP nick end labeling was used to assess the ratio of chondrocytes apoptosis of rabbit knee articular cartilage.
RESULTS AND CONCLUSION:The normal rabbit cartilage tissues and chondrocytes were neatly arranged in column;the middle cartilage layer of the model was thin;the chondrocytes were arranged disorderly and became less. After ultrasound therapy, the chondrocytes were rearranged neatly, and the number was increased. Compared with the normal group, the Mankin scores in the model group and ultrasound group were higher;the apoptotic rate of chondrocytes was higher in the model group and ultrasound group than in the normal group, and was also higher in the model group than in the ultrasound group. Compared with the normal group, the expressions of caspases-3 and caspases-8 were higher in the model group and the ultrasound group, while decreased after ultrasound therapy. The results indicate that ultrasound can improve the structure of cartilage tissues, decrease the expressions of caspases-3 and caspases-8 and reduce the apoptosis rate of chondrocytes. It is effective for the treatment of knee osteoarthritis with ultrasound therapy.

Objective To investigate the expression and signification of B-cell lymphoma/leukemia-2(bcl-2),bax and ER proteins in epithelial cells in different depth of adenomyosis.Methods Expression and correlation of bcl-2,bax and ER proteins were detected by immunohistochemistry staining in 36 adenomyosis cases with superficial (＜ 1/2 depth of penetration) and deep (≥ 1/2 depth of penetration)ectopic endometrium and eutopic endometrial tissues matched with 30 cases with benign ovarian tumor,uterine septum,pelvic floor dysfunction without adenomyosis as controls.Results (1) The expression of ER protein in superficial and deep ectopic tissues (5.04 ±0.24,4.91 ±0.16) were found significantly lower than 6.06 ± 0.36 in eutopic tissues (P ＜ 0.01) and higher than 3.70 ± 0.58 in control group (P ＜ 0.05).There was no statistical difference of ER expression in superficial and deep ectopic endometrium (P ＞ 0.05).(2) The level of bcl-2 protein of 5.6 ± 0.4 in superficial and 6.0 ± 0.3 in deep myometrium of ectopic tissues were significantly higher than 3.6 ± 0.4 in eutopic tissues and 1.9 ± 0.4 in control group (P ＜ 0.01).(3) The level of bax protein of 3.50 ± 0.28 in superficial and 4.80 ± 0.29 in deep myometrial ectopic and 4.43 ± 0.37 in eutopic tissues were significantly lower than 6.18 ± 0.65 in control groups (P ＜0.05).The expression of bax in superficial myometrium is significantly lower than deep myometrium in ectopic tissues (P ＜0.01).(4) The positive correlation between the expression of ER and bcl-2 protein at superficial myometrium of ectopic tissues (r =0.720,P ＜ 0.01).And there was no significant correlation with the expression of ER and bax protein at superficial myometrium (r =0.008,P ＞ 0.05).As well as,there was not significant correlation with the expression of bcl-2,bax and ER protein at deep myometrium (r =0.089,r =-0.023,P ＞ 0.05).The expression of bax protein in ectopic endometrium was positive correlation with the depth of adenomyosis penetration (r =0.736,P ＜ 0.01).There was positive correlation between the expression of ER and bcl-2 protein at normal endometrium (r =0.453,P ＜ 0.05).And there was negative correlation between the expression of ER and bax protein at control group (r =-0.514,P =0.05).Conclusion The bax protein expression of ectopic endometrium in deep adenomyosis was higher than superficial adenomyosis.

Objective To observe the clinical efficacy of staphylococcal protein A immunoadsorption plus nonmyeloablative chemotherapy with CD34+ autologous peripheral blood stem cell transplantation in the treatment of refractory systemic lupus erythematosus (SLE). Methods Three patients with active SLE were enrolled into this study. All patients were diagnosed with lupus nephritis by renal biopsy and poorly responded to routine therapy. Before transplantation, patients were given 6 sessions of immunoadsorption apheresis using columns of staphylococcal protein A-silica with an interval of 3 days; each session processed 3 L plasma and a total of 18 L plasma was processed over the 6 treatments. Three days following the immunoadsorption apheresis, the mobilization of stem cells was realized by intravenous cyclophosphamide at a dose of 2 g per square meter of body surface area and subcutaneous recombinant human granulocyte colony-stimulating factor (G-CSF) at a dose of 5 g per kilogram of body weight per day for 5 days. Then, peripheral blood raonoclonal cells were obtained by CS-3000 Cell Separator, and passed through the Clini Macs CD34+ cell selection device, with the final concentration of CD34+ cells being 2.6×106, 2.1×106 and 2.4×106 per kilogram of body weight respectively, and that of CD3+ cells being 3×105, 2.1×105, and 2.0×105 per kilogram of body weight, respectively, in these three patients. The conditioning regimen consisted of oral fludarabine of 50 mg/d for 5 days plus intravenous pig anti-human thymocyte immunoglobulin (ATG) at a daily dose of 90 mg/kg for 5 days. After 72-hour treatment with ATG, the frozen stem cells were infused back to the patients. Clinical manifestations and lupus-correlated immune parameters were compared in patients at baseline and after transplantation. Results Following immunoadsorption apheresis, an obvious decrease was observed in the level of serum anti-dsDNA, antinuclear antibody and IgG antibodies, while an increase in the level of serum complement 3. All patients achieved the reconstruction of hemopoiesis 2-3 days after the transplantation. Also, an apparent clinical remission was achieved with the SLEDAI score being less than 3. Six months after the transplantation, serum anti-dsDNA and antinuclear antibodies as well as urine protein were undetectable, the level of complement 3 reached the normal range, and renal function was restored. Conclusions Staphylococcal protein A immunoadsorption plus nonmyeloablative CD34+ autologous peripheral blood stem cell transplantation are effective and safe for refractory SLE, but the long-term effect remains to be connfirmed by further studies.
