AIM To explore the clinical effects of Shuilu Erxian Pills combined with Modified Didang Decoction on patients with early and middle stage diabetic nephropathy.METHODS Eighty-three patients were randomly assigned into control group(42 cases)for 12-week administration of Irbesartan Tablets,and observation group(41 cases)for 12-week administration of Shuilu Erxian Pills,Modified Didang Decoction and Irbesartan Tablets.The changes in clinical effects,TCM syndrome scores,blood glucose indices(FBG,HbA1c),blood lipid indices(TC,TG),renal function indices(BUN,Scr,24 h UTP,eGFR),inflammatory factors(IL-1β,hs-CRP,IL-6,TNF-α,IL-18,TGF-β1),immune function indices(lymphocyte,neutrophil,CD8+,CD3+,CD4+,CD4+/CD8+)and incidence of adverse reactions were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the observation group displayed decreased TCM syndrome scores,blood glucose indices,blood lipid indices,BUN,Scr,24 h UTP,inflammatory factors,CD8+(P＜0.05),reduced lymphocyte,neutrophil(P＜0.05),and increased eGFR,CD3+,CD4+,CD4+/CD8+(P＜0.05),which were more obvious than those in the control group(except for HbA1c,TG,SCr,24 h UTP,lymphocyte,neutrophil)(P＜0.05).No significant difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with early and middle stage diabetic nephropathy,Shuilu Erxian Pills combined with Modified Didang Decoction can safely and effectively improve clinical symptoms,whose mechanism may contribute to the reduction of inflammatory levels and improvement of immune functions.

Metabolic dysfunction-associated fatty liver disease (MAFLD) is an increasingly common liver disease worldwide. MAFLD is diagnosed based on the presence of steatosis on images, histological findings, or serum marker levels as well as the presence of at least one of the three metabolic features: overweight/obesity, type 2 diabetes mellitus, and metabolic risk factors. MAFLD is not only a liver disease but also a factor contributing to or related to cardiovascular diseases (CVD), which is the major etiology responsible for morbidity and mortality in patients with MAFLD. Hence, understanding the association between MAFLD and CVD, surveillance and risk stratification of MAFLD in patients with CVD, and assessment of the current status of MAFLD management are urgent requirements for both hepatologists and cardiologists. This Taiwan position statement reviews the literature and provides suggestions regarding the epidemiology, etiology, risk factors, risk stratification, nonpharmacological interventions, and potential drug treatments of MAFLD, focusing on its association with CVD.

Quantity is the key factor to ensure the safety and effectiveness of medicines. It is very important to study and determine the traditional measuring units and their quantity values of Tibetan medicine. Based on the literature records of Tibetan medicine and combined with modern experimental verification and investigation research, this study determined the reference, name, and conversion rate of traditional measuring units of Tibetan medicine. Meanwhile, through large sample sampling and repeated quantification of refe-rence of basic units, its weight and volume were clarified. The modern SI volume and weight unit values corresponding to the traditional volume and weight units of Tibetan medicine were deduced, and the correctness, reliability, and practicability of these determination results were demonstrated. This study also put forward some specific suggestions and reference values for formulating the standards of measuring units of weight and volume of Tibetan medicine. It is of great significance in guiding the processing, production, and clinical treatment of Tibetan medicine, and promoting the standardization and standardized development of Tibetan medicine.

OBJECTIVE: To explore the effect of curcumin on the proliferation of renal cell carcinoma and analyze its regulation mechanism. METHODS: In RCC cell lines of A498 and 786-O, the effects of curcumin (2.5, 5, 10 µ mo/L) on the proliferation were analyzed by Annexin V+PI staining. Besides, A498 was inoculated into nude mice to establish tumorigenic models, and the model mice were treated with different concentrations of curcumin (100, 200, and 400 mg/kg), once daily for 30 days. Then the tumor diameter was measured, the tumor cells were observed by hematoxylin-eosin staining, and the protein expressions of miR-148 and ADAMTS18 were detected by immunohistochemistry. In vitro, after transfection of miR-148 mimics, miR-148 inhibitor or si-ADAMTS18 in cell lines, the expression of ADAMTS18 was examined by Western blotting and the cell survival rate was analyzed using MTT. Subsequently, Western blot analysis was again used to examine the autophagy phenomenon by measuring the relative expression level of LC3-II/LC3-I; autophagy-associated genes, including those of Beclin-1 and ATG5, were also examined when miR-148 was silenced in both cell lines with curcumin treatment. RESULTS: Curcumin could inhibit the proliferation of RCC in cell lines and nude mice. The expression of miR-148 and ADAMTS18 was upregulated after curcumin treatment both in vitro and in vivo (P<0.05). The cell survival rate was dramatically declined upon miR-148 or ADAMTS18 upregulated. However, si-ADAMTS18 treatment or miR-148 inhibitor reversed these results, that is, both of them promoted the cell survival rate. CONCLUSION Curcumin can inhibit the proliferation of renal cell carcinoma by regulating the miR-148/ ADAMTS18 axis through the suppression of autophagy in vitro and in vivo. There may exist a positive feedback loop between miR-148 and ADAMTS18 gene in RCC.

Objective: To investigate the effect and molecular mechanism of ultra-conservative long non-coding RNA uc.77 in lung cancer. Methods: Lung cancer tissues and adjacent normal tissues were obtained from 61 patients with lung cancer who were diagnosed with lung cancer and underwent surgery from 2014 to 2016 in the General Hospital of the Southern Theater Command of the People's Liberation Army. Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the uc.77 relative expressions in normal human bronchial epithelial cells 16HBE, lung cancer cell lines, and 61 pair lung cancer tissues. Uc.77 siRNA was transfected into lung cancer cells to interfere with the expression of uc.77, qRT-PCR was used to verify the interference effect, CCK8 method and clone formation experiment were used to detect cell proliferation ability, flow cytometry was used to detect apoptosis and cell cycle changes. H1299 cells transfected with uc.77 siRNA were injected into the subcutaneous right side of BALB/c nude mice to construct a tumor-bearing model for exploring the role of uc.77 on tumor growth. Western blot and qRT-PCR methods were used to detect the protein and mRNA expressions of p21. Results: The relative expression levels of uc.77 in lung cancer cell lines 95D, H1299, A549, H460, H446 and 16HBE-T were significantly higher than that of 16HBE cells (P<0.05). The uc.77 RNA expression levels of lung cancer tissues was significantly higher than that of the adjacent normal tissues (P<0.001). In addition, increased lncRNA uc.77 expression was significantly associated with big tumor size, lymph node metastasis and advanced TNM stage (P<0.05). After transfection with uc.77 siRNA, the expressions of uc.77 in H1299, 95-D and 16HBE-T cells were reduced (P<0.05), and the cell proliferation capacities were reduced at 48 hours and 72 hours (P<0.05). After transfection with uc.77 siRNA-1, the G(0)/G(1) phase cell ratio of H1299 siRNA-1 group [(71.86±3.46)%] was higher than those of H1299-control group [(47.62±5.48)%] and H1299 siRNA-NC group [(61.38±5.62)%, P<0.05], S phase cell ratio of H1299 siRNA-1 group [(14.99±3.61)%] was lower than those of H1299-control group [(34.95±7.05)%] and H1299 siRNA-NC group [(23.75±5.87)%, P<0.05], the apoptosis rate of H1299 siRNA-1 group [(4.90±1.80)%] was higher than those of H1299-control group [(3.30±0.80)%] and H1299 siRNA-NC group [(2.80±1.20)%, P<0.05], the colony formation rate of H1299 siRNA-1 group [(19.20±2.00)%] was lower than those of H1299 control group [(32.60±2.00)%] and H1299 siRNA-NC group [(34.40±1.00)%, P<0.05]. The results of the nude mice tumor formation experiment showed that the tumor volume of the H1299 siRNA-1 group was significantly lower than those of the H1299-control group and the H1299-negative control group (P<0.05), the average tumor weight of H1299 siRNA-1 group was significantly lower than those of H1299-control group and H1299-negative control group (P<0.05), tumor cell growth marker Ki-67 in the H1299 siRNA-1 group showed weak positive, and Ki-67 in the H1299-control group and H1299-negative control group showed positive. The result of qRT-PCR analysis showed that the mRNA expression level of p21 in H1299 siRNA-1 group (2.57±0.45) was higher than those in H1299 control group (1.00±0.00, P=0.001) and H1299 siRNA-NC group (1.52±0.37, P=0.009). The result of western blotting analysis also showed that the expression of p21 protein level in H1299 siRNA-1 group increased. Conclusions: The expression of ultraconserved long non-coding RNA uc.77 is elevated in lung cancer cell lines and lung cancer tissues. Silencing the expression of ultraconservative long noncoding RNA uc.77 can inhibit tumor growth, and blocking uc.77 expression may be a potential therapeutic target for lung cancer.

OBJECTIVES: To develop a new Chinese medicine (CM)-based drug and to evaluate its safety and effect for suppressing acute respiratory distress syndrome (ARDS) in COVID-19 patients. METHODS: A putative ARDS-suppressing drug Keguan-1 was first developed and then evaluated by a randomized, controlled two-arm trial. The two arms of the trial consist of a control therapy (alpha interferon inhalation, 50 µg twice daily; and lopinavir/ritonavir, 400 and 100 mg twice daily, respectively) and a testing therapy (control therapy plus Keguan-1 19.4 g twice daily) by random number table at 1:1 ratio with 24 cases each group. After 2-week treatment, adverse events, time to fever resolution, ARDS development, and lung injury on newly diagnosed COVID-19 patients were assessed. RESULTS: An analysis of the data from the first 30 participants showed that the control arm and the testing arm did not exhibit any significant differences in terms of adverse events. Based on this result, the study was expanded to include a total of 48 participants (24 cases each arm). The results show that compared with the control arm, the testing arm exhibited a significant improvement in time to fever resolution (P=0.035), and a significant reduction in the development of ARDS (P=0.048). CONCLUSIONS Keguan-1-based integrative therapy was safe and superior to the standard therapy in suppressing the development of ARDS in COVID-19 patients.

A typical clinical case of taking Dictamni Cortex(Baixianpi) powder was analyzed to study liver damage caused by Dictamni Cortex. Liver damage was diagnosed according to the integrated evidence chain method recommended by the Guideline for Diagnosis and Treatment of Herb-Induced Liver Injury. By analyzing clinical history and biochemistry and imaging examinations, underlying diseases, such as viral hepatitis, autoimmune liver disease and alcoholic liver disease, were excluded. Through the investigation of medication history, we made it clear that the patient only took Dictamni Cortex powder during the period, and thus suspected that the liver injury was induced by Dictamni Cortex. Furthermore, the quality of the drug was tested, and the results showed it was consistent with the quality standard of Chinese Pharmacopoeia. DNA barcoding showed that the drug was 100% similar with Dictamnus dasycarpus. Moreover, exogenous harmful substances and chemical drug additions were tested, and the results showed that the content of heavy metal, pesticide residues and microbial toxin were consistent with the required standards, and no chemical drug additions were found in Agilent Fake TCM-Drugs database. In summary, we confirmed that the clinical case of drug-induced liver injury was induced by D. dasycarpus with the dose of 15 g•d⁻¹, which exceeded the prescribed amount of Chinese Pharmacopoeia. According to the Guideline for Diagnosis and Treatment of Herb-Induced Liver Injury, the case of drug-induced liver injury induced by D. dasycarpus was confirmed, which provided a direct and reliable evidence for the study of risk of liver injury induced by D. dasycarpus and its relevant preparations.

Objective To investigate the antibacterial resistance in nationwide's tietiary hospitals and understand the trend of antimicrobial resistance.Methods All the clinical isolates were collected from 18 hospitals and the minimal inhibitory concentrations (MICs) were tested using agar dilution method recommended by Clinical and Laboratory Standards Institute (CLSI) in central laboratory.The susceptibilities of isolates to antimicrobial agents were determined by using CLSI or European Committee on Antimicrobial Susceptibility Testing (EUCAST) 2017 guideline.Results A total of 4333 pathogenic isolates from 18 tertiary hospitals in 18 cities nationwide over the period from July 2015 to June 2016 were studied.Based on the MIC results,Escherichia coli and Klebsiella pneumoniae showed extended spectrum β-lactamase (ESBLs) phenotype rates of 59.4％ and 27.5％,respectively;decreased by 7 to 10 percentage points comparing the last time.Carbapenems,amikacin,moxalactam,β-lactam/β-lactamase inhibitor combinations,tigecycline,and fosfomycin displayed desirable antibacterial activity against Enterbacteriaceae,but a significant increasing of carbapenems resistance Klebsiella pneumoniae were noted.For non-fermenting Gram-negative isolates,resistance rate of Pseudomonas aeruginosa and Acinetobacter baumannnii to imipennnem were 29.5％ and 69.8％ and multidrug-resistant (MDR) detection rate were 35.6％ and 78.3％,extensively drug-resistant (XDR) were 10.2％ and 72.5％,respectively.Klebsiella pneumoniae isolated from children were more resistant to β-lactam than those from adults and the old people,so bacterial resistance in children is an important problem in China.Conclusion Though the decline of ESBLs detection rate,carbapenem non-susceptible Klebsiella pneumoniae rates continued to increase,which should be paid more attention.

Objective To investigate the gram-positive coccus resistance in nationwide's tietiary hospitals and understand the trend of antimicrobial resistance.Methods All the clinical isolates were collected from 18 hospitals and the minimal inhibitory concentrations (MICs) were tested using agar/broth dilution method recommended by Clinical and Laboratory Standards Institute (CLSI) in central laboratory.The susceptibilities of isolates to antimicrobial agents were determined by using CLSI or European Committee on Antimicrobial Susceptibility Testing (EUCAST) 2017 guideline.Results A total of 2301 Gram-positive cocci isolated from 18 hospitals in 18 cities nationwide were studied.Based on the MIC results,the prevalence of methicillin resistant Stapylococcus aureus (MRSA) and methicillin resistant Stapylococcus epidermidis (MRSE) were 39.9％ and 86.6％ respectively.No vancomycin insensitive Staphylococcus was detected.Staphylococcus aureus were 100％ susceptibile to linezolid and teicoplanin,but resistant or insensitive for drugs other than vancomycin were observed among Coagulase Negative Staphylococci (CoNS).Antibiotic resistance rate of Enterococcus faecalis and Enterococcusfaecium to ampicillin were 4.5％ and 85.1％.The detectation rate of vancomycin resistant Enterococcus(VRE) was 2.1％.Nonsusceptibility rate of Enterococcus faecalis to linezolid was 7.8％,showing slight increase than last time.The prevalence of penicillin nonsusceptible Streptococcus pneumoniae (PNSSP) was 6.6％ based on non-meningitis and parenteral administration criterion;while for cases of oral penicillin,the rate was 70.0％,was as flat as last time.There were no significant differenees of resistance rates of Stapylococcus aureus,Stapylococcus epidermidis Enterococcus faecalis and Enterococcus faecium among various groups such as different department,age,or specimen source.Conclusion Compared with past surveillance result,VRE detection ratio was steady,while MRSA detection ratio decreased.The emergence of resistance and non-susceptible strains to new antibiotics such as linezolid,tigecycline and daptomycin should be payed more attention.

OBJECTIVETo investigate the difference in the vulnerability of carotid atherosclerotic plaques in patients with unilateral and bilateral intraplaque hemorrhage (IPH).

METHODSA retrospective analysis was conducted among 44 patients with unilateral IPH (30 cases) or bilateral IPH (14 cases) in the carotid plaques detected by magnetic resonance imaging (MRI) in our hospital between December, 2009 and December, 2012. The age, maximum wall thickness and incidence of fibrous cap rupture were compared between the two groups.

RESULTSCompared with those with unilateral IPH, the patients with bilateral IPHs had a significantly younger age (66.6∓9.4 years vs 73.7∓9.0 years, P=0.027), a significantly greater maximum plaque thickness (6.3∓1.9 mm vs 5.0∓1.3 mm, P=0.035) and a higher incidence of ulcers (50% vs 13.3%, P=0.025). Logistic regression analysis revealed a significant association between bilateral IPHs and the occurrence of ulcer with an odd ratio (OR) of 6.5 (95% confidence interval [CI]: 1.5-28.7, P=0.014). After adjustment for gender in Model 1, bilateral IPHs were still significantly associated with presence of ulcer (OR=5.7, 95%CI: 1.1-29.2, P=0.036). But after adjustment for age (P=0.131) or maximum plaque thickness (P=0.139) in model 2, no significant correlation was found between bilateral IPHs and the presence of ulcer.

CONCLUSIONCompared with patients with unilateral IPH, those with bilateral IPHs are at a younger age and have a greater plaque burden and a higher incidence of fibrous cap rupture, suggesting a greater vulnerability of the carotid plaques in patients with bilateral IPHs.
