In this study, the crude polysaccharides was extracted from Shengfupian and purified by Sevag deproteinization. Then, the purified neutral polysaccharide fragment was obtained by the DEAE-52 cellulose chromatography column and Sephadex G-100 co-lumn. The structure of polysaccharides was characterized by ultraviolet spectroscopy, infrared spectroscopy, ion chromatography, and gel permeation chromatography. To investigate the anti-inflammatory activity of Shengfupian polysaccharides, LPS was used to induce inflammation in RAW264.7 cells. The expression of the CD86 antibody on surface of M1 cells, the function of macrophages, and the content of NO and IL-6 in the supernatant were examined. An immunodepression model of H22 tumor-bearing mice was established, and the immunomodulatory activity of Shengfupian polysaccharides was evaluated based on the tumor inhibition rate, immune organ index and function, and serum cytokine levels. Research indicated that Shengfupian polysaccharides(80 251 Da) was composed of arabinose, galactose, glucose, and fructose with molar ratio of 0.004∶0.018∶0.913∶0.065. It was smooth and lumpy under the scanning electron microscope. In the concentration range of 25-200 μg·mL~(-1), Shengfupian polysaccharides exhibited little or no toxicity to RAW264.7 cells and could inhibit the polarization of cells to the M1 type and reduce the content of NO and IL-6 in the cell supernatant. It could suppress the phagocytosis of cells at the concentration of 25 μg·mL~(-1), while enhancing the phagocytosis of RAW264.7 cells within the concentration range of 100-200 μg·mL~(-1). The 200 mg·kg~(-1) Shengfupian polysaccharides could alleviate the spleen injury caused by cyclophosphamide, increase the levels of IL-1β and IL-6, and decrease the level of TNF-α in the serum of mice. In conclusion, Shengfupian polysaccharides has anti-inflammatory effect and weak immunomodulatory effect, which may the material basis of Aconm Lateralis Radix Praeparaia for dispelling cold and relieving pain.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

In the past 37 years, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has undergone various major transmission routes in China, with the world most complex co-circulating HIV-1 subtypes, even the prevalence is still low. In response to the first epidemic outbreak of HIV in injecting drug users and the second one by illegal commercial blood collection, China issued the Anti-Drug Law and launched the Blood Donation Act and nationwide nucleic acid testing, which has avoided 98,232 to 211,200 estimated infections and almost ended the blood product-related infection. China has been providing free antiretroviral therapy (ART) since 2003, which covered >80% of the identified patients and achieved a viral suppression rate of 91%. To bend the curve of increasing the disease burden of HIV and finally end the epidemic, China should consider constraining HIV spread through sexual transmission, narrowing the gaps in identifying HIV cases, and the long-term effectiveness and safety of ART in the future.

Result:High-frequency medicines of professor HAN Ming-xiang for treating chronic cough were Stemonae Radix, Citri Reticulatae Pericarpium, Asteris Radix et Rhizoma and other 37 herbs, their frequency of occurrence accounted for 80.52%. According to the efficacy, the medicines could be classified into 10 categories, such as expectorant cough antiasthmatic drugs, tonifying deficiency drugs, and diaphoretic drugs. Cluster analysis showed 5 combinations of drugs. Factor analysis yielded 13 common factors, such as Stemonae Radix-Asteris Radix et Rhizoma-Farfarae Flos-Cynanchi Stauntonii Rhizoma et Radix, Asari Radix et Rhizoma-Schisandrae Chinensis Fructus-Zingiberis Rhizoma-Fritillariae Thunbergii Bulbus. Conclusion:Combined with clinical experience, it can be concluded that clinical treatment of professor HAN Ming-xiang for chronic cough attaches great importance to the pathogenesis of wind-evil, Yang deficiency and cold phlegm underlying lung, phlegm and blood stasis and Qi stagnation. The treatment mainly starts from the lung and spleen, with the method of warm and moist, or with some traditional Chinese medicines with the function of removing phlegm by warming the lung, dispersing cold by thinning the surface, strengthening the spleen and resolving phlegm, strengthening the lung and fixing the surface, and relieving spasmolysis by wind.

According to folk usage of Aconitum carmichaelii Debx., the present study was designed to determine the feasibility of the stems and leaves of Aconitum carmichaelii Debx. as a new medicinal resource. Fourteen alkaloids in mother roots, fibrous roots, stems, and leaves of Aconitum carmichaelii Debx. were measured by HPLC-MS/MS. And multivariate analysis methods, such as clustering analysis and principal component analysis, were applied to analyze the difference among various parts. In addition, the acute toxicity, analgesia, and anti-inflammatory tests were carried out. The results suggested that the contents of alkaloids in mother roots and fibrous roots were approximate, but those of leaves and stems were different from mother roots and fibrous roots. The results of the acute toxicity testing demonstrated the toxicity of fibrous root was strongest, and mother roots were slightly less toxic than fibrous roots. The stems and leaves were far less toxic than mother and fibrous roots. In addition, the analgesia and inflammatory tests showed the effects of the various tissues had no difference each other. These results provided a basis for developing new complementary and alternative treatments for rheumatoid arthritis patients. Simultaneously, the approach may also turn wastes into treasure and promote the development of circular economy.

Background: Automated peritoneal dialysis (APD) can cater to individual needs, provide treatment while asleep, take into account the adequacy of dialysis, and improve the quality of life. Currently, independent research and development of APD machines made in China are more conducive to patients. A randomized, multicenter, crossover study was conducted by comparing an APD machine made in China with an imported machine. The safety, effectiveness, and manipulability of the two machines were compared. Methods: Two hundred and sixty patients who underwent peritoneal dialysis (PD) on a regular basis in 18 centers between August 2015 and February 2016 were included. The inclusion criteria include age ≥18 years and PD ≥30 days. The exclusion criteria were as follows: hemodialysis; exit site or tunnel infection; and peritonitis ≤30 days. The patients were randomly divided into Group A, who were first treated with a FM machine made in China, then changed to an imported machine; and Group B, who were treated using the reverse sequence. APD treatment was performed with 10 L/10 h and 5 cycles of exchange. After 72 h, the daily peritoneal Kt/V, the accuracy of the injection rate, accuracy of the injection temperature, safety, and manipulability of the machine were assessed. Noninferiority test was conducted between the two groups. Results: The daily peritoneal Kt/V in the APD machine made in China and the imported APD machine were 0.17 (0.14, 0.25) and 0.16 (0.13, 0.23), respectively. There was no significant difference between the groups (Z = 0.15, P = 0.703). The lower limit of the daily Kt/V difference between the two groups was 0.0069, which was greater than the noninferiority value of -0.07 in this study. The accuracy of the injection rate and injection temperature was 89.7% and 91.5%, respectively, in the domestic APD machine, which were both slightly better than the accuracy rates of 84.0% and 86.8% in the imported APD machine (89.7% vs. 84.0%, P = 0.2466; 91.5% vs. 86.8%, P = 0.0954). Therefore, the APD machine made in China was not inferior to the imported APD machine. The fuselage of the imported APD machine was space-saving, while the APD machine made in China was superior with respect to body mobility, man-machine dialog operation, alarm control, and patient information recognition. Conclusions: The FM machine made in China was not inferior to the imported APD machine. In addition, the FM machine made in China had better operability.

Objective To study the influence of targeted inhibition of Notch1 gene on the killing effects of paclitaxel on triple negative breast cancer cells. Methods The triple negative [estrogen receptor (ER)/progesterone receptor (PR)/human epidermal growth factor receptor 2 (Her2)] breast cancer cell line MDA-MB-231 and ER/PR/HER-2-positive breast cancer cell line MCF-7 were cultured, transfected with Notch1-siRNA-overexpression plasmid and blank plasmid, and treated with different concentrations of paclitaxel, and then the cell proliferation activity and apoptosis rate as well as the mRNA expression of Caspase-3, Caspase-9 and Bcl-2 were determined. Results Paclitaxel could decrease the MDA-MB-231 and MCF-7 cell proliferation activity as well as Bcl-2 mRNA expression, and increase MDA-MB-231 and MCF-7 cell apoptosis rate as well as Caspase-3 and Caspase-9 mRNA expression in dose-dependent manners; with the same dose of paclitaxel treatment, the inhibitory effects on MDA-MB-231 cell proliferation activity and Bcl-2 mRNA expression as well as the promoting effects on MDA-MB-231 cell apoptosis and mRNA expression of Caspase-3 and Caspase-9 were weaker than those on MCF-7 cell; after 0.5 μM paclitaxel combined with Notch1-siRNA treatment, MDA-MB-231 cell proliferation activity and Bcl-2 mRNA expression were significantly lower than those after 0.5 μM paclitaxel combined with control plasmid treatment while cell apoptosis rate and mRNA expression of Caspase-3 and Caspase-9 were higher than those after 0.5 μM paclitaxel combined with control plasmid treatment. Conclusions Targeted inhibition of Notch1 gene may enhance the killing effects of paclitaxel on triple negative breast cancer cells by up-regulating the expression of Caspase-3 and Caspase-9 and inhibiting the expression of Bcl-2.

OBJECTIVETo study the influence of leukodeplated blood transfusion on cellular immunity of patients with acute leuemia, so as to provide support for application of leuko-deplated blood transfusion in clinic.

METHODSA total of 100 AL patients from January 2012 to December 2015 were chosen, and were divided into 2 groups: leukodeplated blood transfusion group(50 cases) and routine blood transfusion group(RBT) as control (50 cases). The effective rate, side effects, peripheral blood T cells and expression level of TLR2 and TLR4 were compared between 2 groups.

RESULTSThe expression levels CD3(+), CD4(+), CD8(+), CD4(+)/CD8(+) of TLR2 and TLR4 in control group were (52.18±2.14)%, （27.28±1.19）%,（24.21±1.65）%,1.22±0.18,0.62±0.04 and 0.57±0.05, respectively, after treatment; while these indicators in LdBT group were （52.18±2.14）%,（30.97±2.01）%,（27.08±1.55）%,1.39±0.24,0.91±0.06 and 0.87±0.07, respectively, and above-mentioned indicators in LdBT group were significantly higher than those in control group（P<0.05）. Compared with these indicators before treatment, CD3(+), CD4(+), CD8(+) and CD4(+)/CD8(+) in the patients increased significantly（P<0.05）. The efficiency was 92.00% (46/50) in LdBT group, and 84.00% (42/50) in control group, without statistically significant difference（P>0.05）. The rate of side effects in study group was 6% (3/50), 18% (9/50) in control group, with statistically significance difference （P<0.05）.

CONCLUSIONLeukodeplated blood transfusion can improve the cellular immunity of AL patients, and reduce the rate of side effects.

OBJECTIVETo compare efficacy differences between fire filiform needle combined with mild moxibustion and gabapentin combined with sham acupuncture for postherpetic neuralgia (PHN).

METHODSOne hundred cases of PHN were randomly divided into a needle group and a medicine group, 50 cases in each one. In the needle group, pricking method of fire filiform needle was given at the Ashi points, and then mild moxibustion was applied for 15 min. In the medicine group, the oral administration of gabapentin capsule and sham acupuncture at non-acupoints in the distal end of lesions were applied. The treatment was required for 21 days in both groups. The visual analogue score (VAS) was recorded before treatment and on the 1st day, 2nd day, 3rd day, 6th day, 9th day and 12th day of treatment. The most severity of pain within last 24 h, preset severity of pain, immediate analgesia effect and starting time of pain relief were observed, also the efficacy was assessed and improvement of symptoms was observed in the follow-up visit.

RESULTSThe total effective rate was 94.0% (47/50) in the fire filiform needle group, which was superior to 86.0% (43/50) in the medicine group (P < 0.05). Compared with medicine group, the VAS of the most severity of pain within last 24 h was obviously reduced after the 2nd treatment in the fire filiform needle group while that of present severity of pain was relieved after the 1st treatment (both P < 0.05). The immediate analgesia effect in the fire filiform needle group was obviously superior to that in the medicine group in the first three times of treatment (all P < 0.05). The average time of pain relief was (3.91 +/- 0.82) days in the fire filiform needle group, which was significantly earlier to (6.53 +/- 1.13) days in the medicine group (P < 0.05). 26 cases were cured in the fire filiform needle group in the follow-up visit, which was superior to 2 cases in the medicine group (P < 0.05). The improvement of VAS, pain range and sleep quality in the needle group were also superior to those in the medicine group (all P < 0.05). The direct medical cost in the fire filiform needle group was (232.32 +/- 48.108) yuan, which was significantly lower than (466.00 +/- 41.09) yuan in the medicine group (P < 0.05). There was only one case of adverse effect in the medicine group during the treatment.

CONCLUSIONThe fire filiform needle combined with mild moxibustion could obviously relieve the pain in PHN patients, which has superior immediate analgesia effect and pain relieving time compared with gabapentin, which also has less adverse effects and cheap cost.
