Objective To investigate intradermal injection and subcutaneous injection of Gadodiamide MR lymphangiography (MRL) in evaluation on the central conducting lymphatics in rabbits.Methods T1 weighted three-dimendional fast low angle shot (fl3d) sequence was used before and after administration of Gadodiamide to undertake MRL.Gadodiamide was administed intrademally in the left and right footpad in 8 rabbits,and then undertake MRL in 1.5T MRI system (intradermal injection group).Three days later,Gadodiamide was administered subcutaneously in the left and right footpad in 8 rabbits,and MRL were underdone with the same sequence (subcutaneous injection group).The degree of contrast enhancement within the lumbar lymphatic trunk and thoracic duct were evaluated using a 3-point scoring system.Results Intradermal injection group showed the popliteal lymph nodes,sacral lymph node and inferior aortic lymph node enhanced obviously in all 8 rabbits,and the enhancement duration time was about 30 90 mini the lumbar lymphatic trunk and cisterna chyli were detected in 6 rabbits,and part of the thoracic duct were detected in 5 rabbits.Subcutaneous injection group showed the popliteal lymph nodes enhanced obviously in all 8 rabbits,but the lumbar lymphatic trunk and the thoracic duct were not detected.The score of contrast enhancement within the lymphatic system of intradermal injection group and subcutaneous injection group had statistical difference (t=100.00,P=0.0002).Conclusion MRL with intradermal injection Gadodiamide are better than subcutaneous injection in evaluation of the lumbar lymphatic trunk.

Objective To investigate the effect of cluster needling at scalp points plus gavage of modified Buyang Huanwu decoction on NSC differentiation in rats with ischemic stroke of qi deficiency and blood stasis type.Methods A model of qi deficiency and blood stasis syndrome was made using healthy rats. Dil dye was given for pre-labelling after the success of model making. The rats were randomized into groups A, B, C, D, E and F. Group F consisted of 4 rats and each of the other groups, of 12 rats. A rat model of ischemic stroke of qi deficiency and blood stasis type was made by MCAO at 48 hrs after pre-labelling. After the success of model making, group A was the model group, group B was treated by cluster needling at scalp points, group C was treated by an oral gavage of Buyang Huanwu decoction, group D was treated by an oral gavage of modified Buyang Huanwu decoction, group E was treated by cluster needling at scalp points plus an oral gavage of modified Buyang Huanwu decoction and group F was the sham operation group. The rats were sacrificed at various time points respectively and the materials were taken. By nerve function assessment, double immunofluorescence staining and laser scanning confocal microscopy, a comparative study was conducted to investigate the effects of different treatments on NSC differentiation.Results There was a statistically significant difference in the nerve function score between group B, C, D, E or F and group A after one week of treatment (P<0.01), between group B or E and group A after two weeks of treatment (P<0.05,P<0.01) and between group E and group C or D after one and two weeks of treatment (P<0.01,P<0.05). After one and two weeks of treatment, there were statistically significant differences in Brdu﹢/NeuN﹢ cell count, Brdu﹢/GFAP﹢ cell count, Dil﹢/Brdu﹢NeuN﹢ cell count and Dil﹢/Brdu﹢/GFAP﹢ cell count between group B, C, D or E and group A (P<0.01), between group D or E and group B or C (P<0.01) and between groups E and D (P<0.01).Conclusions Various treatments have a promoting effect on nerve stem cell differentiation in the rats. Of various treatments, cluster needling at scalp points plus gavage of modified Buyang Huanwu decoction has the best therapeutic effect.

Objective:To explore the effects of acupuncture combined with Buyang Huanwu Decoction on intestinal flora in cerebral blood flow hypo perfusion model rats with carotid artery stenosis.Methods:Totally 40 rats were randomly divided into sham-operation group, model group, TCM treatment group and acupuncture and drug combination treatment group, with 10 rats in each group. Except the sham-operation group, the other groups were prepared cerebral ischemia model by needle control and thread embolism method. TCM treatment group received Buyang Huanwu Decoction 100 mg/kg for gavage, once a day, and the intervention lasted for 2 weeks. In the acupuncture and drug combination group, based on the TCM treatment group, Baihui and its left and right sides of 2 mm were selected for acupuncture, once a day, and continuous intervention was performed for 2 weeks. Neurological function evaluation and behavioral function score were performed 7 and 14 days after administration, respectively. 16S rRNA sequencing was used to comprehensively characterize the structure and composition of fecal microflora of rats in each group. Linear discriminant analysis Effect Size (LEfSe) was used to analyze the difference of intestinal bacteria among groups.Result:On the 7th and 14th day after administration, compared with the model group, the neurological function score in the TCM treatment group and the acupuncture and drug combination group decreased ( P<0.05), and the behavioral function score increased ( P<0.05). Compared with model group, the Shannon index of TCM treatment group and acupuncture and drug combination group increased ( P<0.05). The abundance of Firmicutes increased ( P<0.05), and the abundance of Bacteroidetes and Proteobacteria decreased ( P<0.05); the abundance of Clostridia increased ( P<0.05), and the abundance of Gammaproteobacteria decreased ( P<0.05). The abundance of Escherichia-Shigella and Bacteroides decreased ( P<0.05); the abundance of lactobacillus significantly increased ( P<0.05). Conclusion:Acupuncture combined with Buyang Huanwu Decoction can improve the symptoms of cerebral hypoperfusion model rats with carotid artery stenosis, and the mechanism may be to increase the abundance of probiotics.

Objective:To observe and compare the efficacy and safety of glucosamine sulfate (GS) and chondroitin sulfate (CS) in the treatment of adult Kashin-Beck disease (KBD), so as to provide effective medical evidence for the standardized treatment of adult KBD.Methods:A clinical randomized controlled trial was conducted in Fuyu County and Shangzhi City, KBD historical seriously ill areas in Heilongjiang Province. A total of 247 patients were selected according to the standard of "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010). According to gender, age and KBD condition, they were randomly divided into GS and CS groups, 124 and 123 respectively. Follow up once a month to investigate the medication and clinical symptoms of patients, and distribute drugs for the next stage. Fasting blood and urine samples were collected before, during and at the end of treatment (0, 90 and 180 d). Serum interleukin (IL)-1β content and urine pyridine (PYD) level were measured by enzyme-linked immunosorbent assay (ELISA). The visual analogue scale (VAS) score, affected joints, self-evaluation of curative effect and side effects were evaluated through the questionnaire, joint dysfunction and drug efficacy were evaluated according to the criteria of "Evaluation of Therapeutic Effect of Kashin-Beck Disease" (WS/T 79-2011).Results:Expression of cytokines related to cartilage metabolism: at 180 d of treatment, serum IL-1β contents and urinary PYD levels in GS and CS groups were lower than those at 0 d of treatment ( Z = - 2.461, - 2.160, - 5.075, - 5.471, P < 0.05). VAS score: at 90 and 180 d of treatment, the scores of knee pain, stiffness and function in GS and CS groups were lower than those at 0 d of treatment ( P < 0.05); and at 180 d of treatment, the scores of knee stiffness and function in GS group were lower than those in CS group ( P < 0.05). Evaluation of affected joints: at 90 and 180 d of treatment, the scores of joint pain, swelling and stiffness in GS and CS groups were lower than those at 0 d of treatment ( P < 0.05). Self-evaluation of curative effect: at 180 d of treatment, the self-evaluation of curative of CS group were better than that at 90 d of treatment (χ 2 = 9.376, P < 0.05). Evaluation of side effects: at 90 and 180 d of treatment, the side effects in GS and CS groups were mainly gastrointestinal symptoms. Joint dysfunction score: at 90 d of treatment, the sum of effective rate and markedly effective rate in GS group was higher than that in CS group (χ 2 = 4.042, P < 0.05), but there was no significant difference between the two groups at 180 d of treatment (χ 2 = 0.869, P > 0.05). Conclusion:GS and CS have certain therapeutic effects on adult KBD, which can improve symptoms and reduce serum IL-1β content and urinary PYD level, but GS takes effects quickly, and its effect on improving joint stiffness and function are better than CS.

Objective:To observe and compare the therapeutic effects of glucosamine sulfate (GS) and diacerein (DCN) on adult Kashin-Beck disease (KBD).Methods:A clinical randomized controlled trial was conducted in the historical severe KBD areas Fanrong Township, Fulu Town, Long'anqiao Town, Lianghe Town, Shaowen Township of Heilongjiang Province, and 240 patients were selected according to the criteria of "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010), then divided into GS and DCN groups (gender, age, and KBD condition balanced) via the random number table method, with 120 patients in each group. Followed up once a month to investigate the patient's medication and clinical symptoms, and distributed drugs for the next stage. Fasting blood samples and urine samples were collected before, during, and at the end of treatment (0, 90, and 180 days). Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum interleukin (IL)-1β level and urine pyridinol (PYD) level. Visual analog scale (VAS) scores, evaluation of affected joints, self-evaluated efficacy, and evaluation of adverse reactions were carried out through questionnaires. Joint dysfunction scores and medications efficacy determination were performed according to the "Judgment of Kaschin-Beck Disease Treatment Effect" (WS/T 79-2011).Results:Expression of cytokines related to cartilage metabolism: after 180 days of treatment, serum IL-1β levels, urine PYD levels in GS group and urine PYD levels in DCN group were lower than those in the same group at 0 day of treatment ( Z = - 2.332, - 5.420, - 5.204, P < 0.05). VAS scores: after 90 days of treatment, the pain, stiffness scores of patients in GS group and the pain, stiffness, and function scores in DCN group were lower than those in the same group at 0 day of treatment ( Z = - 2.612, - 2.359, - 3.637, - 2.881, - 2.238, P < 0.05); after 180 days of treatment, the pain, stiffness and function scores of patients in GS and DCN groups were significantly lower than those of the same group at 0 day of treatment ( Z = - 6.738, - 9.530, - 7.781, - 5.428, - 3.761, - 3.587, P < 0.01).

Efficacy self-evaluation: after 180 days of treatment, the self-evaluated efficacy ratio of DCN group was higher than that of GS group and the same group after 90 days of treatment (χ 2 = 4.165, 4.022, P < 0.05). Evaluation of adverse reactions: after 90 and 180 days of treatment, the main adverse reactions of patients in GS and DCN groups were gastrointestinal symptoms. Joint dysfunction scores: after 90 days of treatment, the sum of the effective rate and the markedly effective rate of GS group was higher than that of DCN group (χ 2 = 4.993 , P < 0.05); while after the 180 days of treatment, there was no significant difference between the two groups (χ 2 = 0.417 , P > 0.05). Conclusions:Both GS and DCN have a certain therapeutic effect on adult KBD and can improve clinical symptoms. The GS takes effect quickly, and long-term use can protect cartilage from inflammatory factors to a certain extent.

Objective:To investigate the effects of glucosamine sulfate, chondroitin sulfate and diacetarine on urinary renal function indexes UREA, creatinine (CREA), urinary microprotein(mALB) and N-acetyl-β-D-glucosidase (NAG) in adult patients with Kashin-Beck disease.Methods:According to the criteria of "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010), adult patients with degrees Ⅰ and Ⅱ Kashin-Beck disease in Heilongjiang Province were selected in 2019. They were randomly divided into three treatment groups according to age, gender, disease classification and other condition by clinical randomized controlled trial, group A (glucosamine sulfate group), group B (chondroitin sulfate group) and group C (diacetarine group). Fasting mid-morning urine was collected at 0, 90 and 180 days of treatment. The levels of UREA, CREA, mALB and NAG were measured using an automatic biochemical analyzer. And the abnormal rates of the above indexes were analyzed.Results:At 0 day of treatment, there were 118, 99 and 116 people in the 3 groups, respectively; after 90 days of treatment, 115, 93 and 106 people remained in the 3 groups; after 180 days of treatment, 95, 80 and 93 people remained in the 3 groups. The results showed that there was no significant difference in the levels of UREA, CREA, NAG and mALB among the 3 groups at 0 and 180 days of treatment ( H = 0.055, 0.923, 0.276, 1.125, 1.635, 3.873, 1.045, 4.135, P > 0.05). After 90 days of treatment, there was no significant difference in CREA level among the 3 groups ( H = 1.719, P > 0.05), the levels of UREA and NAG in group C were higher than those in group B ( P < 0.05), and the level of mALB in group B was higher than that in group C ( P < 0.05). The comparison results of all indexes before and after treatment showed that after 90 days of treatment, the levels of mALB in the 3 groups were lower than those of 0 day ( Z = - 2.858, - 3.217, - 2.124, P < 0.05), the levels of NAG were higher than those of 0 day ( Z = - 3.700, - 2.222, - 4.672, P < 0.05); and the level of UREA in group C was higher than that of 0 day ( Z = - 2.393, P < 0.05). After 180 days of treatment, the levels of CREA in the 3 groups were higher than those of 0 day ( Z = - 5.853, - 6.984, - 6.255, P < 0.05), and the levels of mALB in the 3 groups were lower than those of 0 day ( Z = - 3.785, - 2.624, - 3.427, P < 0.05). The abnormal rates of CREA in the 3 groups after 180 days of treatment were higher than those of 0 and 90 days (χ 2 = 39.499, 37.707, 71.534, 57.959, 58.160, 55.129, P < 0.05). There was no significant difference in the abnormal rate of CREA between 0 day and 90 days of treatment (χ 2 = 0.004, 2.068, 0.053, P > 0.05). The abnormal rates of NAG in groups A and C after 90 days of treatment were higher than those of 0 day (χ 2 = 8.999, 11.227, P < 0.05). The abnormal rates of NAG in group C after 180 days of treatment was higher than that of 0 day (χ 2 = 5.006, P < 0.05). There was no significant difference in the abnormal rate of NAG between group A and group C after 90 days and 180 days of treatment (χ 2 = 1.976, 1.413, P > 0.05). The abnormal rates of mALB in groups A and B after 90 days and 180 days of treatment were lower than those of 0 day (χ 2 = 6.461, 8.881, 7.563, 4.999, P < 0.05), and there was no significant difference between 90 days of treatment and 180 days of treatment (χ 2 = 0.638, 0.013, P > 0.05). Conclusions:The effects of glucosamine sulfate, compound chondroitin sulfate and diacetarine on renal function of the patients are not significantly different after 180 days of medication, but the three drugs all have certain effects on CREA and NAG. Follow-up work should be done during drug treatment to closely monitor the changes of the two indicators.
