Objective To investigate the effects of Pollen Typhae total flavone ( PTF) , an extract from Pollen Typhae which has the actions of activating blood and removing stasis, on inflammatory factors and insulin sensitivity in type 2 diabetic rats. Methods SD rats were used as the experimental animal. Type 2 diabetic rats induced by high fat diet plus low dose of streptozotocin were randomly divided into model group, PTF group (in the dosage of 200 mg·kg-1·d-1) , and rosiglitazone group (in the dosage of 4 mg·kg-1·d-1) . Additionally, normal control group was set up. After treatment for 4 weeks, plasma interleukin 6 ( IL-6) and tumor necrosis factor alpha ( TNF-α) levels were detected, the insulin tolerance test ( ITT) was performed, and the protein expression of suppressor of cytokine signaling-3 ( SOCS-3) in skeletal muscle was determined. Results After treatment for 4 weeks, the plasma levels of IL-6 and TNF-α, the homeostasis model of insulin resistance ( HOMA-IR) , and expression level of SOCS-3 in skeletal muscle in the model groups were significantly increased ( P﹤0.05) as compared with those in the normal control group, and insulin tolerance was also impaired in the model group ( P﹤0.05) . Compared with the model group, IL-6 level and HOMA-IR were markedly decreased in the PTF group ( P﹤0.05) , and the impaired insulin tolerance was obviously improved (P﹤0.05) . The level of SOCS-3 in the skeletal muscle of PTF group was also much lower than that of the model group and rosiglitazone group (P﹤0.05) . Conclusion PTF has effects on decreasing the levels of plasma IL-6 and SOCS-3 in the skeletal muscle and on improving insulin sensitivity in type 2 diabetic rats.

Objective To investigate the effects of Pollen Typhae total flavone (PTF) on INS-1 pancreaticβcell damage induced by palmitic acid ( PA) . Methods INS-1 pancreatic β cells were given long-term induction with PA to establish the impaired cell model, and then were intervened with PTF. Cell viability was determined by tetrazolium salt ( XTT) colorimetry. Results PA impaired the viabilities of INS-1 pancreatic β cells in concentration- and time-dependent manner, and PTF improved the impairment of INS-1 pancreatic β cells induced by PA in concentration -dependent manner. Moreover, PTF showed better improvement on the impairment when the INS-1 pancreatic β cells were impaired more seriously by PA. Conclusion PTF has effects on ameliorating the impairment of INS-1 pancreaticβcells induced by PA for long time.

Objective To compare the pain management effects between painless wards with quality control circle mode and conventional pain management mode.Methods A retrospective case control study was conducted on the clinical data of 233 patients with lower limb fracture admitted from August 2015 to August 2016.There were 124 males and 109 females,aged 18-74 years [(48.3 ±3.3)years].The patients were divided into observation group (n =117) and control group (n =116) according to the pain management mode.The observation group followed the standard continuous quality improvement program and combined with professional team and patients Wechat group to implement pain management,and further measures were taken in accordance with the feedbacks.The control group adopted routine painless ward nursing model for perioperative analgesia nursing intervention.The pain score VAS,the start time of functional exercise,the compliance of rehabilitation activities,the length of hospital stay,and the healing time of fracture were compared between the two groups.Results There was no significant difference in VAS scores between the two groups at 12 hours before operation and 6 hours after operation (P ＞ 0.05).The observation group had lower VAS scores at 12 hours (3.2± 1.4),24 hours (2.8 ±0.9),48 hours (1.6 ± 0.7),and 72 hours (1.5 ± 0.8) after operation than the control group (P ＜0.05).The observation group started functional exercises earlier [(18.9 ± 0.4) hours after operation]than the control group earlier [(48.1 ± 1.7) hours after operation] (P ＜ 0.01).The observation group had a rehabilitation compliance rate of 62.6％,higher than that of the control group (17.6％) (P ＜0.05).The hospital stay [(12.18 ± 0.14) days] and fracture healing time [(97.86 ± 0.83) days] of the observation group were shorter than those of the control group (P ＜ 0.05).Conclusion The pain management model of standardized continuous quality improvement can significantly relieve pain in patients with lower limb fracture,shorten hospitalization time,bring forward the start time of functional exercise,improve the compliance of rehabilitation activities,and promote fracture healing.

OBJECTIVE:To systematically evaluate therapeutic efficacy of modified Shenqi dihuang decoction in the treatment of chronic glomerular nephritis. METHODS:Retrieved from Wanfang database,CNKI,VIP,CBM,Cochrane Library,Medline, EMBase and PubMed,randomized controlled trials(RCTs)about modified Shenqi dihuang decoction combined with conventional therapy and (or) other Chinese patent medicine (trial group) vs. conventional therapy and (or) other Chinese patent medicine (control group)in the treatment of chronic glomerular nephritis were collected. Meta-analysis was carried out by using Rev Man 5.3 software after literature scanning,data extraction and quality evaluation. Stata 14.0 software was used to conduct Egger test to evaluate publication bias. If publication bias existed,the effect of publication bias on outcome was further evaluated by scissor compensation. TSA v0.9 software was used for trial sequential analysis(TSA)of total efficency. RESULTS:A total of 10 RCTs were included,involving 707 patients. The results of Meta-analysis showed that total response rate of trial group [RR＝1.40,95%CI(1.22, 1.61),P＜0.001] was significantly higher than that of control group; the level of urine protein [SMD＝－1.97,95%CI(－2.92,－1.03),P＜0.001] and Scr [MD＝－28.41,95%CI(－38.95,－17.87),P＜0.001] in trial group were significantly lower than control group,with statistical significance. Publication bias test of total response rate was conducted,and results of it showed that there was publication bias,but bias did not affect the results of this study. TSA analysis showed that the evidence of Meta-analysis was false positive. CONCLUSIONS:Therapeutic efficacy of modified Shenqi dihuang decoction for chronic glomerular nephritis need to be proved by more stringent RCTs.

Objective To evaluate different methods in detecting intraperitontal free cancer cells (IFCCs) in patients with gastric cancer and to clarify the relationship between positive IFCCs and short-term prognosis.Methods A total of 119 gastric cancer patients who underwent surgical treatment were enrolled.Peritoneal lavage was performed with 300-400 ml saline respectively at three points of time:immediately after abdominal cavity entry;when surgical operation was completed;when extensive intraoperative peritoneal lavage was done.The IFCCs were detected with methods of traditional centrifugal cytology,membrane cytology,ICC and RT-PCR.The survival curve of patients with gastric cancer was drawn using Kaplan-Meier method.Results The positive rate of PLC was 16.8％,20.7％ and 11.2％ respectively at 3 timepoints (P ＜ 0.05).The positive rates of ICC were 28.6％,38.8％ and 20.7％ respectively at 3 timepoints.The positive rates of RT-PCR were 39.3％,69.5％ and 50.8％ respectively at 3 time points.The positive rate of IFCCs detected through RT-PCR was higher than that of PLC and ICC (P ＜ 0.05).The short-term prognosis of patients with positive IFCCs was worse than those with negative results detected with any three method at the timg point immediately after opening the abdomen (P ＜ 0.05).At the timg point immediately after removing the tumors,the short-term prognosis of patients with positive IFCCs detected with PLC was worse (P ＜ 0.05).Conclusion The short-term prognosis was poor in patients with positive IFCCs.It is the best time to detect IFCCs before radical resection.Surgical procedures increase the risk of shedding of IFCCs.

Objective: This study’s objective is to assess the efficacy and safety of Pulsed Magnetic Therapy System (PMTS) in improving insomnia disorder. Methods: Participants with insomnia disorder were randomly assigned to receive either PMTS or sham treatment for four weeks (n= 153; PMTS: 76, sham: 77). Primary outcomes are the Insomnia Severity Index (ISI) scores at week 0 (baseline), 1, 2, 3, 4 (treatment), and 5 (follow-up). Secondary outcomes are the Pittsburgh Sleep Quality Index at baseline and week 4, and weekly sleep diary-derived values for sleep latency, sleep efficiency, real sleep time, waking after sleep onset, and sleep duration. Results: The ISI scores of the PMTS group and the sham group were 7.13±0.50, 11.07±0.51 at week 4, respectively. There was a significant group×time interaction for ISI (F3.214, 485.271=24.25, p<0.001, ηp 2=0.138). Only the PMTS group experienced continuous improvement throughout the study; in contrast, the sham group only experienced a modest improvement after the first week of therapy. At the end of the treatment and one week after it, the response of the PMTS group were 69.7% (95% confidence interval [CI]: 58.6%–79.0%), 75.0% (95% CI: 64.1%–83.4%), respectively, which were higher than the response of the sham group (p<0.001). For each of the secondary outcomes, similar group×time interactions were discovered. The effects of the treatment persisted for at least a week. Conclusion PMTS is safe and effective in improving insomnia disorders.

The prevalence of osteoporosis， osteoarthritis， gouty arthritis， rheumatoid arthritis， and intervertebral disc degeneration is increasing year by year with the growing number of elderly people， and the common clinical manifestations of these diseases include severe pain in different areas， which seriously affects the daily life of the patients. Therefore， how to relieve the pain and reduce the prevalence of bone and joint diseases and improve the quality of life of the patients is a hot spot in the medical field. Studies have confirmed that NOD-like receptor family， pyrin domain-containing protein 3 （NLRP3） inflammasomes， as pattern recognition receptors， are involved in the inflammation， chondrocyte proliferation， osteoblast and osteoclast differentiation， intervertebral disc cell inflammation and scorching， extracellular matrix degradation and apoptosis， mitochondrial dysfunction， endoplasmic reticulum stress， and reactive oxygen species damage， demonstrating close link with the development of bone and joint diseases. Chinese medicine has a long history and demonstrates remarkable therapeutic effects in the treatment of bone and joint diseases. It can mitigate the pathological changes of bone and joint diseases by inhibiting NLRP3 inflammasomes to alleviate the pain， playing a role in preventing and treating these diseases. Therefore， this paper briefly describes the relationship between NLRP3 inflammasomes and the development of bone and joint diseases by reviewing the latest research progress at home and abroad. We summarize the latest studies about the active components， extracts， and compound prescriptions of Chinese medicines in the treatment of bone and joint diseases via regulating NLRP3 inflammasomes. This review is expected to offer new insights into the in-depth research on the pathogenesis and drug treatment of bone and joint diseases and provide a basis for the clinical application of Chinese medicine in the prevention and treatment of such diseases.

【Objective】 To summarize a rapid and effective method to eliminate autoantibodies interference with blood group identification and evaluate its treatment effect. 【Methods】 Blood samples with suspicious results in initial blood group identification were collected, and those caused by autoantibodies were chosen, and their red blood cells were washed, dispersed or treated with sulfhydryl reagent. After allogeneic or autologous absorption of plasma, blood groups of those patients were re-detected to evaluate the effectiveness of the above method. 【Results】 Among 39 patients presenting suspicious ABO blood group, 9 were interfered by autoantibodies. After appropriate treatment, the ABO/RhD blood group of those patients could be identified. 【Conclusion】 Autoantibodies could interfere the identification of ABO/RhD blood group, and the efficiency and accuracy of blood group identification could be improved by analyzing the test results and selecting appropriate treatment methods.
