Objective To observe the clinical efficacy of ZHU Lian's acupuncture activating method with type 1 manipulations in treating hypotonic cerebral palsy.Method Sixty patients with hypotonic cerebral palsy, aged 9-59 months, were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by ZHU Lian's acupuncture activating method with type 1 manipulations, while the control group was intervened by acupoint injection of vitamin B1 and B12. The two groups were treated once a day, 5 sessions as a treatment course. The Gross Motor Function Measure-88 (GMFM-88) was evaluated before the treatment and after 10 treatment courses.Result The GMFM-88 score was significantly changed after the treatment in both groups (P<0.05). After the intervention, the GMFM-88 score in the treatment group was significantly different from that in the control group (P<0.05).Conclusion ZHU Lian's acupuncture activating method is an effective approach in treating hypotonic cerebral palsy.

A total of 52 endophytic fungi were isolated from roots and stems of Tibetan medicinal plant Phlomis younghusbandii Mukerjee. These fungal isolates were molecularly identified based on ITS sequnces and 28S sequences distributed to 12 genera, including Phoma, Chaetosphaeronema, Fusarium and Leptosphaeria, etc. Among them, the dominant genus was Phoma. Extracts of all strains were evaluated for anti-HIV-1 integrase activity by using soluable integrase expressed in E. coli BL21 (DE3). The results showed that seven samples from five fungal endophytes PHY-24, PHY-38, PHY-40, PHY-51, PHY-53, which belonged to genus Chaetosphaeronema, inhibited strand transfer reaction catalyzed by HIV-1 integrase with IC50 values, of 6.60, 5.20, 2.86, 7.86, 4.47, 4.56 and 3.23 microg x mL(-1) respectively. In conclusion, the endophytic fungi of Phlomis younghusbandii Mukerjee are valuable for further screening anti-HIV-1 integrase agents.

Objective To measure the number of peripheral blood CD34+ hematopoietic stem/progenitor cells (HSC/HPCs) and membrane expression of CD34 on these cells in patients with SLE. Methods Lymphocytes were isolated from peripheral blood of 30 patients with SLE and 14 normal human controls. Flow cytometry using FITC-labeled antibodies was performed to determine the percentage of CD34+ HSC/HPCs and mean fluorescence intensity (MFI) of CD34 on these cells. Their correlation with clinical data was analyzed.Results The percentage of CD34+ HSC/HPCs in peripheral lymphocytes was (0.15 ± 0.10)% and (0.09 ±0.07)% in active and stable SLE patients, respectively, significantly lower than that in normal controls [(0.37 +0.17)%, F = 17.18, P < 0.01], however, there was no significant difference between active and stable SLE patients (t = 1.51, P> 0.05). The MFI of CD34 was higher in active SLE patients than in the normal controls (41.35 ± 19.24 vs. 27.43 ± 7.57, F= 3.13, P < 0.05), but no difference was observed between stable SLE patients and normal controls (F= 3.13, P > 0.05). In patients with SLE, the percentage of CD34+ HSC/HPCs was negatively correlated with serum IgG levels (r = -0.588, P < 0.01 ), but uncorrelated with SLE disease activity index (SLEDAI) or serum levels of complement, anti-dsDNA antibodies, anti-C1q antibodies, antinucleosome antibodies, etc. Conclusions The count of CD34+ HSC/HPCs is reduced while the MFI of CD34 antigen is elevated in SLE patients, hinting that there is a functional abnormality of HSC/HPCs in SLE patients, which may be involved in the pathogenesis of SLE.

Objective To measure the number of peripheral blood CD34+ hematopoietic stem/progenitor cells (HSC/HPC) expression of CD34 in the peripheral blood of patients with rheumatoid arthritis and exploreits relationship with clinical manifestations. Methods CD34+ HSC/HPCs in the peripheral blood of RA patients (n=32) and healthy controls (n=16) were detected using flow cytometry. The relationship between the frequency of HSC/HPCs, mean fluorescence intensities (MFI) of CD34 and clinical manifestations and rheumatoid factor (RF), anti-cyclic citrullinated peptide (CCP) antibodies, disease activity score (DAS) 28,X rays stages and healthy assessment questionnaire (HAQ) were analyzed. Student's t-test and pearont test were used for statistical analysis. Results Frequency of CD34+ HSC/HPC in the peripheral blood of RA patients was decreased compared with normal controls [ (0.13±0.09)% vs (0.38±0.21)%, P<0.05 ], CD34 MFIwere higher in RA patients than those in the normal controls (57±33 vs 3111, P<0.05). The frequency was positively correlated with the number of (RBC red blood cell), (Hb hemoglobin), and was negatively correlated with C-reactive protein (CRP), and the MFI of RA patients was positively correlated with healthy assessment questionnaire (HAQ) and X ray stages, but negatively correlated with the number of platelets.Conclusion CD34+ HSC/HPC of the peripheral blood of RA patients are significantly abnormal, which is characterized by decreased CD34+ hematopoietic stem cell, and the decrease is positively correlated with RBC and Hb, but negatively correlated with CRP. CD34+ hematopoietic stem cell may play an important role in the pathogenesis of RA.

This study is to establish physiologically based pharmacokinetic (PBPK) models of famitinib in rat and monkey, and then to predict the pharmacokinetics and tissue distribution of famitinib in human based on the PBPK models. According to published paper, previous studies and the chemical properties of famitinib predicted by ACD/ADME suite and SimCYP, the PBPK models of rat and monkey were established and optimized using GastroPlus. And then, the PBPK models were applied to predict the pharmacokinetic and tissue distribution of famitinib in human. The results showed that the PBPK models of rat and monkey can fit the observed data well, and the AUC0-∞, ratios of observed and calculated data in rat and monkey were 1.00 and 0.97, respectively. The AUC0-∞, ratios of observed and predicted data in human were 1.63 (rat to human) and 1.57 (monkey to human), respectively. The rat and monkey PBPK models of famitinib were well established, and the PBPK models were applied in predicting pharmacokinetic of famitinib in human successfully. Hence, the PBPK model of famitinib in human could be applied in future drug-drug interaction study.
