Gut Microbiota Alteration Influences Colorectal Cancer Metastasis to the Liver by Remodeling the Liver Immune Microenvironment

Background/Aims@#This study aimed to explore the effect of gut microbiota-regulated Kupffer cells (KCs) on colorectal cancer (CRC) liver metastasis. @*Methods@#A series of in vivo and in vitro researches were showed to demonstrate the gut microbiota and its possible mechanism in CRC liver metastasis. @*Results@#Fewer liver metastases were identified in the ampicillin-streptomycin-colistin and colistin groups. Increased proportions of Parabacteroides goldsteinii, Bacteroides vulgatus, Bacteroides thetaiotaomicron, and Bacteroides uniforms were observed in the colistin group. The significant expansion of KCs was identified in the ampicillin-streptomycin-colistin and colistin groups. B.vulgatus levels were positively correlated with KC levels. More liver metastases were observed in the vancomycin group. An increased abundance of Parabacteroides distasonis and Proteus mirabilis and an obvious reduction of KCs were noted in the vancomycin group. P. mirabilis levels were negatively related to KC levels. The number of liver metastatic nodules was increased in the P. mirabilis group and decreased in the B. vulgatus group. The number of KCs decreased in the P. mirabilis group and increased in the B. vulgatus group. In vitro, as P. mirabilis or B. vulgatus doses increased, there was an opposite effect on KC proliferation in dose- and time-dependent manners. P. mirabilis induced CT26 cell migration by controlling KC proliferation, whereas B. vulgatus prevented this migration. @*Conclusions@#An increased abundance of P. mirabilis and decreased amount of B. vulgatus play key roles in CRC liver metastasis, which might be related to KC reductions in the liver.

Clinical practice guideline for postmenopausal osteoporosis with traditional Chinese medicine / 中国中药杂志

The editorial group of the clinical practice guideline for postmenopausal osteoporosis(PMOP) with traditional Chinese medicine(TCM)(hereinafter referred to as "guideline") is composed of experts specialized in TCM orthopedics, TCM gynecology, clinical epidemiology, etc. The guideline was formulated through registration, collection and selection of clinical issues/outcome indicators, evidence retrieval and screening, preparation of systematic reviews, evaluation of evidence quality, formation of recommendations, drafting, and peer review. The syndromes and treatment of PMOP are elaborated in detail. Specifically, Liuwei Dihuang Pills and Zuogui Pills are recommended for PMOP with Yin deficiency in the liver and kidney, Qing'e Pills for PMOP with kidney deficiency and blood stasis, Yougui Pills and Jingui Shenqi Pills for PMOP with Yang deficiency in the spleen and kidney, and Er'xian Decoction for PMOP with Yin and Yang deficiency in the kidney. In addition, Duhuo Jisheng Decoction can be used to relieve pain. The commonly used Chinese patent medicines include Xianling Gubao Capsules, Qianggu Capsules, Jintiange Capsules, Gushukang Capsules, Hugu Capsules, Jinwu Gutong Capsules, and Guyuling Capsules. Acupuncture and moxibustion are also effective approaches for PMOP. The rehabilitation and daily management were carried out by exercise therapies such as Baduanjin(eight-section brocade), Wuqinxi(five-animal exercises), and Taijiquan(Tai Chi), Chinese medicine diet, health education, and fall prevention. The promotion and application of this guideline will facilitate the implementation of TCM prevention and treatment of PMOP, ensure the quality of life of PMOP patients, provide effective and safe TCM treatment measures for PMOP, and reduce the risk of fracture complications.

Randomized controlled trial outcome indicators of postmenopausal osteoporosis treated by traditional Chinese medicine / 中国中药杂志

This study evaluated the outcome indicators of the randomized controlled trials(RCTs) of traditional Chinese medicine(TCM) in the treatment of postmenopausal osteoporosis(PMOP) to provide a reference for the related research. Four Chinese databa-ses(CNKI, VIP, Wanfang and CBM) and three English databases(Cochrane Library, EMbase and PubMed) were searched syste-matically to screen RCTs of TCM in the treatment of PMOP according to the pre-set criteria, and the quality of the included trials was evaluated by the Cochrane risk-of-bias tool. A total of 29 627 articles were initially retrieved, and finally, 43 articles were included, including 34 in Chinese and 9 in English. As revealed by the results, the outcome indicators of 43 RCTs were mainly divided into six categories, with biochemical indicators accounting for 54.59%, bone mineral density(BMD) for 26.57%, quality of life for 6.28%, fracture for 1.94%, safety for 5.31%(including adverse reactions or events) and others for 5.31%. Biochemical indicators showed the maximum occurrence, followed by BMD. Many problems were found in the selection of outcome indicators of the TCM RCTs in the treatment of PMOP, such as the confusion of primary and secondary outcome indicators, the lack of endpoint criteria and vital clinical outcome indicators substituted by intermediate indicators, inconsistent evaluation standard of syndrome curative efficacy and neglected blinding in the measurement of subjective outcome indicators. The problems also included importance given to the efficacy indicators instead of the adverse outcome indicators, unnormalized indicator name, large quantitative range of the indicators, unconventional application of TCM efficacy criteria, seldom used confidence interval, relative effect indicator and absolute effect indicator.

Systematic review on efficacy and safety of Lanqin Oral Liquid in treatment of hand, foot and mouth disease / 中国中药杂志

Lanqin Oral Liquid is a Chinese patent medicine which contains Isatidis Radix, Scutellariae Radix, Gardeniae Fructus, Phellodendri Chinensis Cordex and Sterculiae Lychophorae Semen. It is known for the pharmaceutical effect on the upper respiratory tract infection as it is beneficial for relieving the swelling of pharyngeal. In terms of Chinese medicine, it offers a clearing action on heat and toxic materials. According to the principle of Chinese medicine, different diseases can be treated by the same therapy as long as they have the same syndrome. Based on this unique diagnosis and treatment approach, Lanqin Oral Liquid was applicable to diseases with syndrome of excessive heat in lung and stomach. It was therefore commonly be used in the therapeutic approach towards hand, foot and mouth disease as well. However, no systematic evaluation had yet been done to verify this Chinese patent medicine on the efficacy and clinical safety for the disease. In order to achieve the manner of evidence-based medicine, this study had adopted a systematic review and Meta-analysis to evaluate the efficacy and safety of Lanqin Oral Liquid in the treatment of hand, foot and mouth disease. All related randomized controlled trials(RCT) were searched in the following data bases: CNKI, WanFang, VIP, SinoMed, Cochrane Library and PubMed. Based on the method provided by the Cochrane collaboration, the study assessed the quality of papers selected and RevMan 5.3 software was used to perform Meta-analysis. Totally 24 studies were included with 3 491 sample size, which 1 826 cases were treatment group and 1 665 cases were control group. From the results of Meta-analysis, the total effective rate of combination of Lanqin Oral Liquid and Western medicines shown better than Western medicine alone in the treatment for hand, foot and mouth di-sease, but mild adverse event were also found(RR=1.20,95%CI[1.16,1.23],P<0.000 01). Incidence of adverse reaction between experimental and control group was statistically insignificant(RR=1.16, 95%CI[0.79, 1.70], P=0.45). No conclusion was able to made in terms of the remission time of clinical symptoms, as the studies included were not qualified for Meta-analysis. As a matter of fact, the number of existing studies related to the Lanqin Oral Liquid were limited with poor quality as well. In other words, high quality studies were essential to further evaluate the efficacy and safety of Lanqin Oral Liquid.

Systematic review and Meta-analysis on randomized controlled trials on effectiveness and safety of Kudiezi Injection in treatment of acute cerebral infarction / 中国中药杂志

To systematically review the effectiveness and safety of Kudiezi Injection in treating patients with acute cerebral infarction( ACI). Four Chinese databases( CNKI,VIP,Wan Fang,Sino Med),three English databases( Cochrane Library,EMbase,Medline)and Clinical Trail.gov were systematically and comprehensively retrieved. The retrieval time was from the establishment of each database to November 2017. Randomized controlled trials( RCTs) for the treatment of acute cerebral infarction with Kudiezi Injection were screened out according to pre-established inclusion criteria and exclusion criteria. The quality of the included studies was assessed using the Cochrane Risk Assessment Tool,and the included studies were put into descriptive analysis or Meta-analysis using the Rev Man 5. 3 software. A total of 932 articles were retrieved,and finally 14 studies were included. Except for 2 multi-arm trials,the total sample size was 1 244 in the experimental group and 638 in the control group. The overall quality of the included studies was not high. The results of Meta-analysis showed that Kudiezi + conventional therapy for acute cerebral infarction was superior to conventional therapy in total effective rate( RR = 0. 86,95% CI[0. 77,0. 96],P = 0. 006); Kudiezi + conventional therapy for acute cerebral infarction was superior to conventional therapy in serum inflammatory factors( MDhs-CRP=-3. 77,95% CI[-4. 17,-3. 37],P < 0. 000 01; MDIL-18=-16. 18,95% CI[-19. 26,-13. 11],P<0. 000 01); Kudiezi + conventional therapy was superior to conventional therapy in Barthel index( MD = 12. 52,95%CI[8. 93,16. 10],P<0. 000 01). Adverse reactions included in the study reports showed mild adverse reactions. Based on the results of this study,Kudiezi Injection combined with conventional therapy or other Western medicine had a certain curative effect on acute cerebral infarction,with no serious adverse reactions. However,due to the low quality of the included research methodology,the conclusions of this study were not recommended. In addition,in order to produce high-quality evidence for the clinical application of Kudiezi Injections,more randomized controlled trials with a large sample size,scientific design and strict implementation were required to study the effectiveness and safety of Kudiezi Injection in the treatment of cerebral infarction.

Efficacy and safety of Breviscapine Injection in treatment of diabetic nephropathy: systematic review and Meta-analysis of randomized controlled trials / 中国中药杂志

This study aimed to systematically evaluate the efficacy and safety of Breviscapine Injection in the treatment of diabetic nephropathy( DN). Eight electronic databases and Clinical Trials.gov were searched to collect randomized controlled trials on Breviscapine Injection in the treatment of DN. According to the Cochrane Handbook 5. 1,two independent reviewers screened out the literatures,extracted data and assessed the quality of the studies included. Rev Man5. 3 software was used for the data analysis. A total of 29 studies containing 37 trials were included,involving 2 097 patients,1 054 cases in test groups and 1 043 cases in control groups. The clinical studies included had a low overall quality. According to Meta-analysis: ①Conventional therapy plus breviscapine injection was superior to conventional therapy in total efficiency rate,24 h UTP,SCR,BUN,UEAR,ALB and m ALB during DN stage Ⅲ( RRtotal effective rate=1. 60,95%CI [1. 32,1. 93],P<0. 000 01; SMD24 h UTP=-1. 21,95%CI[-1. 56,-0. 87],P<0. 000 01; MDSCR=-6. 33,95%CI[-9. 20,-3. 46],P<0. 000 1; MDBUN=-6. 6,95%CI[-1. 10,-0. 22],P = 0. 003; MDUEAR=-20. 30,95%CI [-28. 14,-12. 46],P<0. 000 01; MDALB= 0. 47,95%CI[0. 42,0. 52],P<0. 000 01; MDmALB=-10. 03,95%CI[-10. 62,-9. 46],P<0. 000 01). ②Conventional therapy plus Breviscapine Injection was better than conventional therapy in total efficiency rate( only 1 study),24 h UTP,SCR and BUN during DN stage Ⅳ( RRtotal effective rate= 1. 57,95% CI[1. 10,2. 25],P = 0. 01; SMD24 h UTP=-0. 52,95% CI [-0. 71,-0. 33],P<0. 000 01; MDSCR=-35. 38,95%CI[-48. 57,-22. 19],P<0. 000 01; MDBUN=-1. 89,95%CI [-3. 01,-0. 77],P<0. 000 01). ③Conventional therapy plus Breviscapine Injection was better than conventional therapy in SCR( MD =-26. 35,95% CI[-47. 45,-5. 24],P= 0. 01),but with no significant difference in 24 h UTP,BUN and ALB during DN stageⅤ. ④It was impossible to obtain the specific judgment information on the adverse reactions of Breviscapine Injection in the treatment of the disease from the existing evidences. The current evidences suggest that the combination of Breviscapine Injection and conventional therapy had a certain curative effect in the treatment of DN,especially in stages Ⅲ and Ⅳ. The safety of Breviscapine Injection needs to be further explored.Because the low quality of the study impacted the accuracy of the result,more rigorous,high-quality,multi-center,randomized doubleblind controlled trials are required to increase the support of the evidences in the future.

Efficacy and safety of breviscapine injection in treatment of unstable angina pectoris: systematic review and Meta-analysis / 中国中药杂志

To systematically evaluate the efficacy and safety of breviscapine injection in the treatment of unstable angina pectoris (UAP). Eight electronic databases and clinical trials registries were searched to collect randomized controlled trials on breviscapine injection in the treatment of UAP. According to the evaluation standards in Cochrane Handbook 5.1, two independent reviewers screened out the literature, extracted data and assessed the quality of the studies included. RevMan 5.3 software was used for Meta quantitative analysis and corresponding description analysis. A total of 36 studies involving 3 058 patients were included, 1 552 cases in the trial group, 1 506 cases in the control group, 1 846 males and 1 212 females. All the clinical studies showed a low quality. Meta-analysis results showed that the combination of breviscapine injection and conventional therapy was superior to conventional therapy in angina pectoris efficacy (RRangina pectoris efficacy=1.29, 95%CI[1.23,1.35],<0.000 01；RRECG1=1.25,95%CI[1.12,1.38],<0.000 1；RRECG2=1.38,95%CI[1.27,1.49],<0.000 01); descriptive analysis of a single study showed that the efficacy of combination of breviscapine injection and conventional therapy was superior to that of conventional therapy alone. In respect of hemorheology, the combination of breviscapine injection and conventional therapy was better than conventional therapy in lowering LBV and EAI (MDLBV=-1.27,95%CI[-1.55,-0.99],<0.000 01；MDEAI=-0.38,95%CI[-0.60,-0.16],=0.000 6), as well as in lowering WBV and HCT in the descriptive analysis of single study. In respect of blood lipid, the combination of breviscapine injection and conventional therapy was better than conventional therapy in lowering TC, TG and LDL-C (MDTC=-0.30,95%CI[-0.51,-0.10],=0.003；MDTG=-0.32,95%CI[-0.77,0.13],=0.16；MDLDL-C=-0.45,95%CI[-0.76,-0.14],=0.004). In reducing the frequency of angina attacks, heart rate, high sensitive C-reactive protein and improving exercise tolerance, the combination of breviscapine injection and conventional therapy was also superior to the conventional therapy alone (MDFAP=-3.30,95%CI[-4.06,-2.54],< 0.000 01；MDHR=-9.38,95%CI[-12.78,-5.98],=0.000 2；MDhs-CRP=-0.56,95%CI[-0.85,-0.27],=0.000 2；MDET=0.88,95%CI[0.41,1.35],=0.000 2). The main adverse reactions in the two groups included headache, dizziness, palpitations, nausea, abdominal distension, skin pruritus, flushes and allergic reactions in the study. The safety of breviscapine injection needs to be further studied and clarified because of the combination of drugs and the incomplete information reported in the original study. The current evidence suggested that the combination of breviscapine injection and conventional therapy had certain advantages in curative effect for the treatment of UAP. Due to the low quality of the study and its own shortcomings, it is necessary to design more rigorous, high-quality, multi-center randomized double-blind controlled trials to increase the strength of the evidence.

Effectiveness and safety of Kudiezi injection in treating coronary angina pectoris: systematic review and Meta-analysis of randomized controlled trials / 中国中药杂志

To evaluate the effectiveness and safety of Kudiezi injection in the treatment of angina pectoris of coronary heart disease. Four Chinese databases (CNKI, VIP, WanFang, and SinoMed) and three English databases (Cochrane Library, Medline, and ClinicalTrail.gov) were systematically and comprehensively searched from the establishment of each database to March 2018. Randomized controlled trials (RCTs) on the treatment of angina pectoris of coronary heart disease with Kudiezi injection (KDZ) were screened according to the pre-established inclusion criteria and exclusion criteria. The quality of the included studies was evaluated by using the ROB tool developed by the Cochrane Collaboration, and RevMan 5.3 software was used for Meta-analysis. A total of 712 articles were retrieved and finally 38 studies were included. The total sample size was 3 812 cases, 1 945 in the experimental group and 1 867 in the control group. The overall quality of the included studies was generally low. The results of Meta-analysis showed that: KDZ combined with conventional or western medicine was superior to conventional or western medicine alone in the effectiveness and electrocardiogram efficacy of angina pectoris and unstable angina. The descriptive analysis showed that KDZ combined with conventional treatment group was superior to conventional treatment group in agina pectoris associated indicators of angina pectoris and unstable angina. Other outcome measures were easily affected by various factors (such as too large heterogeneity of outcome indicators) and could not be concluded. Adverse reactions included in the study report were all mild adverse reactions and did not affect treatment. Based on the results of this study, it can be seen that Kudiezi injection had a certain effect on the treatment of angina pectoris of coronary heart disease, especially with significant positive effect on the improvement of the curative effect for angina pectoris and the effect of electrocardiogram. No serious adverse reactions occurred. However, due to the limited number of studies included, the generally low quality of the included studies, and the existence of published biases, the quality of the evidence in this study was low, so that caution should be taken to apply this conclusion. The effectiveness and safety of Kudiezi injection in the treatment of angina pectoris of coronary heart disease remained to be confirmed in the future with a well-designed and rigorous multi-center randomized controlled trials with standardized report, large sample, and enough follow-up time.

Methodological quality and reporting quality evaluation of randomized controlled trials published in China Journal of Chinese Materia Medica / 中国中药杂志

To evaluate the methodological quality and reporting quality of randomized controlled trials(RCTs) published in China Journal of Chinese Materia Medica, we searched CNKI and China Journal of Chinese Materia webpage to collect RCTs since the establishment of the magazine. The Cochrane risk of bias assessment tool was used to evaluate the methodological quality of RCTs. The CONSORT 2010 list was adopted as reporting quality evaluating tool. Finally, 184 RCTs were included and evaluated methodologically, of which 97 RCTs were evaluated with reporting quality. For the methodological evaluating, 62 trials(33.70%) reported the random sequence generation; 9(4.89%) trials reported the allocation concealment; 25(13.59%) trials adopted the method of blinding; 30(16.30%) trials reported the number of patients withdrawing, dropping out and those lost to follow-up;2 trials （1.09%） reported trial registration and none of the trial reported the trial protocol; only 8(4.35%) trials reported the sample size estimation in details. For reporting quality appraising, 3 reporting items of 25 items were evaluated with high-quality,including: abstract, participants qualified criteria, and statistical methods; 4 reporting items with medium-quality, including purpose, intervention, random sequence method, and data collection of sites and locations; 9 items with low-quality reporting items including title, backgrounds, random sequence types, allocation concealment, blindness, recruitment of subjects, baseline data, harms, and funding;the rest of items were of extremely low quality(the compliance rate of reporting item<10%). On the whole, the methodological and reporting quality of RCTs published in the magazine are generally low. Further improvement in both methodological and reporting quality for RCTs of traditional Chinese medicine are warranted. It is recommended that the international standards and procedures for RCT design should be strictly followed to conduct high-quality trials. At the same time, in order to improve the reporting quality of randomized controlled trials, CONSORT standards should be adopted in the preparation of research reports and submissions.

Objective@#To investigate the correlation of the single nucleotide polymorphism (SNP) rs1042522 of the tumor protein p53 (TP53) gene with the risk of male infertility.@*METHODS@#This casecontrol study included 380 male patients with idiopathic infertility and 398 normal fertile men as controls from the Nanjing area. We genotyped the SNP rs1042522 of the TP53 gene by Sequence Mass Array and analyzed the correlation of the SNP with male infertility using the logistic regression model.@*RESULTS@#Compared with the normal controls, the patients with idiopathic infertility showed significantly decreased sperm concentration (［77.34±49.24］ vs ［13.13±24.96］ ×106/ml), percentage of progressively motile sperm (［42.55±9.57］ vs ［10.38±5.57］%), serum testosterone level (［14.07±5.36］ vs ［11.89±4.50］ nmol/L), and folliclestimulating hormone level (［16.80±18.20］ vs ［4.55±7.17］ U/L) (P < 0.05) but no statistically significant differences in other parameters. No correlation was observed between the SNP frequencies and male infertility and similar results were found in the subgroups of the cases.@*CONCLUSIONS@#SNP rs1042522 of the TP53 gene is not significantly correlated with the risk of male infertility.

Efficacy of mild hypothermia therapy on pulmonary function in ARDS dogs / 天津医药

Objective To investigate the efficacy of mild hypothermia therapy on pulmonary function in acute respiratory distress syndrome (ARDS) dogs. Methods A total of 25 healthy dogs were included and randomly divided into two groups, mild hypothermia treatment group (experimental group, n=12) and normothermia treatment group (control group, n=13). The E. coli was pumped continuously into the canine femoral vein by micro pump to construct the septic shock model in two groups. The hypothermia experimental group was treated with hypothermia (33℃±1℃), and the control group was observed at room temperature. The pulmonary hemodynamic parameters and respiratory mechanics parameters were supervised by PICCO and respirator respectively at 0, 24 and 48 h during the ARDS progress. Moreover, chest X-ray and lung tissue biopsy were taken to confirm the diagnosis of ARDS after 72 h. Results Up to 72 h, ARDS was found in the experimental group (n=4) and the control group (n=7) respectively. The oxygenation index (OI), partial pressure of oxygen [p(O2)] and pulmonary static compliance (Cst) decreased gradually with the extension of time in two groups. On the contrary, the external venous lung water index (EVLWI), pulmonary vascular permeability index (PVPI) and airway resistance (Raw) increased gradually (P<0.05). However, all the parameters were significantly better in mild hypothermia group than those of the normothermia group. Conclusion Mild hypothermia therapy can improve the pulmonary function and reduce the severity of ARDS in septic shock dogs.

Objective · To investigate the prevalence of smoking and awareness of smoking hazards in a community-based elderly population in Changning District, Shanghai. Methods · A total of 1809 subjects were randomly selected from 18 communities based on the chronic non-communicable diseases cohort in an elderly population aged 65 and over in Changning District, Shanghai. Information on smoking status, health condition and awareness of smoking hazards were obtained through face to face interviews. Chi-square tests and non-conditional Logistic regression analyses were used to evaluate the risk factors of the awareness of smoking hazards and current smoking status. Results · The overall prevalence of current smoking was 15.6% among the investigated elderly population. Smoking prevalence was significantly higher in men than that in women (30.0% vs 2.1%, P=0.000). Also, it was higher in the men aged 65-69 than that in those aged 70 and over (34.3% vs 20.4%, P=0.000). The participants with middle school education had the highest prevalence (19.1%) in the population. Overall, the proportion of participants who knew "smoking causes heart disease" "smoking causes stroke"and "smoking causes cancer" was 45.1%, 43.3% and 64.4%, respectively. Among the participants, 36.4% knew all the three smoking hazards. With the confounders such as age and gender being adjusted, current smoking behavior was associated with the participants' awareness of smoking hazards (OR=0.74,P=0.000). Conclusion · Currently, the awareness of smoking hazards is generally low in Shanghai elderly population, especially in those with lower education level and current smoking behavior. More targeted educational interventions are necessary in specific population.
