ABSTRACT
Licorzine granules are common preparations for children zinc deficiency. Considering the long course of treatment, the taste of licorzine granules may become a main factor affecting medication adherence. To date there have been no taste evaluation research into licorzine granules yet. In this study, both sensory evaluation and electronic tongue method were utilized to optimize licorzine granules formulations, evaluate the tastes of licorzine, excipients, optimized formulation in vivo and in vitro. As the results show, bitterness and astringency are the main unpleasant tastes generating from licorzine. Xanthan gum is the main taste-masking excipient, lowering down the bitterness and astringency of licorzine by at least one grade. Good correlation exists between the results of sensory evaluation and electronic tongue method, and an integrated combination of the two helps to obtain objective and rational research conclusions. The adult sensory evaluation study was a research-based clinical trial conducted with informed consent from all subjects in accordance with the ethical requirements of Good Clinical Practice.

ABSTRACT
Recently we witness the rising number of genetically modified (GM) soybean (Glycine max) events approved for importing from abroad and developed domestically, so it is urgent to establish a rapid screening protocol that can cover more events with less detection targets and fit the national condition. Additionally, in order to control the detection workload, it is also necessary to construct a multi-targets plasmid (MTP) molecule that can be used as the positive material. In this study, the information of the transgenic elements in 29 GM soybean events was collected and the combinations and frequencies of these elements were analyzed, to establish a novel screening protocol. It includes eight detecting targets, CaMV 35S promoter (P-35S), NOS terminator (T-nos), herbicide tolerance gene pat, E9 terminator (T-E9), insecticidal gene cry1Ac, AHAS promoter (P-AHAS), pin Ⅱ terminator (T-pin Ⅱ), and the event-specific sequence of the transgenic event DP305423, and an endogenous reference gene of soybean Lectin. After validation, the 29 GM soybean events described above can be screened by detection of the nine targets. This is referred to as the “8+1” protocol for GM soybean screening. Then these targeted sequences described in the protocol were simultaneously inserted into a cloning vector to construct the corresponding MTP pDDSC-1910. Finally, we tested whether it could be a positive plasmid. As expected, PCR analysis using pDDSC-1910 as a template showed that specific amplicons were observed with high sensitivity. Therefore, the “8+1” screening protocol for GM soybean was established, and the positive plasmid molecule pDDSC-1910 containing corresponding targets was successfully constructed. These results would facilitate the efficient screening and detection of transgenic soybeans.

Objective:To evaluate the rapid diagnostic value of serum novel coronavirus (2019-nCoV) IgM/IgG detection in COVID-19, aiming to further improve the diagnostic and screening system of COVID-19.Methods:Blood samples were collected from 32 patients with COVID-19 (tested positive for 2019-nCoV nucleic acid by RT-PCR and presented with clinical symptoms) and 34 non-COVID-19 patients (tested negative for 2019-nCoV nucleic acid by RT-PCR and clinically confirmed as non-COVID-19 patients). Colloidal gold-based immunochromatography was used for rapid detection of 2019-nCoV IgM/IgG in these samples. The sensitivity and specificity of the test, and the correlation of serum 2019-nCoV IgM/IgG with disease course were analyzed.Results:Among the 32 COVID-19 patients, nine tested positive for 2019-nCoV IgM with a positive rate of 28.1% (9/32) and 25 positive for 2019-nCoV IgG with a positive rate of 78.1% (25/32). The total positive rate was 84.4% (27/32). Two of the 34 non-COVID-19 patients tested positive for 2019-nCoV IgG with a positive rate of 5.9% (2/34), while none of them was positive for 2019-nCoV IgM. The positive rates of serum IgM were 42.9% (3/7), 30.8% (4/13) and 16.7% (2/12) at 10-20 d, 21-30 d and 31-40 d after the patients developed the symptoms of COVID-19, respectively, which showed a decreasing tread with prolonged disease course. The positive rates of serum IgG in COVID-19 patients were 57.1% (4/7), 84.6% (11/13) and 83.3% (10/12) at 10-20 d, 21-30 d and 30-40 d after symptom onset. The rate showed an increasing trend with prolonged disease course and reached the peak in about 21-30 d.Conclusions:Serum 2019-nCoV IgM/IgG detection (using colloidal gold method) had high sensitivity (84.4%) and strong specificity (94.1%) in the diagnosis of 2019-nCoV infection. It had a great value in the diagnosis and screening of COVID-19 and could be used as a valuable complementary method to the COVID-19 diagnostic system due to its advantages of flexibility, rapidity and simplicity.
ABSTRACT
Objective To evaluate the consistency among the results of preoperative midstream urine culture (PMUC), renal pelvis urine culture (RPUC) and renal stone (RSC) culture in patients undergoing percutaneous nephrolithotomy (PNL) and their relationship with postoperative infection. Methods This was a multicenter prospective study. From September 2014 to November 2017, 115 patients undergoing standard channel PNL or microchannel PNL in the First Affiliated Hospital of Soochow University and Yancheng Hospital of Traditional Chinese Medicine were selected. The PMUC, RPUC and RSC were detected. Samples for RPUC and RSC were obtained during PNL. The clinical data, stone configuration, stone burden and results of cultures were recorded. Results In the 115 patients, PMUC positive was in 4 cases (3.5%), RPUC positive was in 17 cases (14.8%), and RSC positive was in 16 cases (13.9% ); both RPUC and RSC positive were in 7 cases (6.1% ), among whom consistent pathogenic bacterium was in 6 cases, and inconsistent pathogenic bacterium was in 1 case; all the 3 cultures were positive in 1 case, but the types of pathogenic bacterium of PMUC were totally different with RPUC and RSC. At least one positive of the 3 cultures was in 29 cases (25.2% ). The types of pathogenic bacterium of PMUC were multidrug susceptible Escherichia coli and Staphylococcus aureus , and the types of pathogenic bacterium of RPUC and RSC were multidrug resistant pathogens and/or fungus. The consistency of pathogenic bacterium between PMUC and RPUC, RSC was very low; while the consistency of pathogenic bacterium between RPUC and RSC was very high (6/7). Postoperative infection occurred in 8 of 115 patients (7.0% , 5 cases of infective fever and 3 cases of urinary sepsis). In the 8 patients, PMUC was negative, PRUC positive in 4 cases, RSC positive in 7 cases, and both PRUC and RSC positive were in 3 cases. Conclusions PMUC can not accurately reflect the true situation of upper urinary tract renal calculi and pyelo-urine pathogenic bacterium. In patients with PNL postoperative infectious complications, the result of PMUC is often negative, but the results of RPUC and RSC are mostly positive. RPUC and RSC are helpful to detecting pathogenic bacterium in time, guiding the application of sensitive antibiotics, preventing and treating PNL postoperative infection.

A novel method for rapid detection of arginine based on fluorescence resonance energy transfer effect (FRET) between carbon quantum dots ( CQDs) and gold nanoparticles ( AuNPs) was developed. Firstly, the CQDs with excellent fluorescence properties were synthesized by one-step microwave assisted method. The AuNPs/ CQDs composites were characterized and their quenching mechanism was analyzed. Then the amount of AuNPs/ CQDs, the pH value and the reaction time were optimal. Under the optimum conditions, the fluorescence system was used to detect the content of arginine, showing a good linear relationship ( R2 = 0. 993 ) between fluorescence intensity and concentration of arginine in the range of 0. 1-10. 0 μmol/ L, and the detection limit was 5. 8 nmol/ L. Finally, the content of arginine in grape juice was determined by this method with recoveries of 105. 4％ -110. 8％ , which indicated that the proposed FRET system had the potential for practical detection of arginine in fruit juice.
ABSTRACT
Objective:To determine the correlations of single nucleotide polymorphisms (SNPs) with atrial fibrillation (AF) in the Chinese Han population from the central plains.Methods:A total of 168 hospitalized patients,including 56 AF and 112 controls,were recruited in this case-control study.The clinical data were obtained from the medical records.All 5 SNPs,rs337711 in KCNN2,rs11264280 near KCNN3,rs17042171 near PITX2,rs6771157 and rs6795970 in SCN10A,were genotyped using amplification refractory mutation system-polymerase chain reaction or direct sequencing.The x2 test was used to compare categorical variables and preliminarily examine correlations between the genotype frequencies and AF.Subsequently,a logistic regression model was constructed to determine the associations between the SNPs and AF based on the above screened results.Odds ratios (ORs) and 95％ confidence interval (CI) were calculated to assess the strength of the correlations.Moreover,we downloaded the genotype data from the HapMap Project for linkage disequilibrium analysis ofrs17042171.Results:AF patients were likely to be of older age and longer left atrial diameter and had more coronary artery disease and higher hypertension compared with the control group (P＜0.05).Among the 5 SNPs,the frequency distribution of genotype AA for rs17042171 was significantly different between the AF and control groups (P＜0.05).After adjusting for several covariates,there was still a high risk ratio in patients with the AA genotype compared with the AC+CC genotype (OR:5.591,95％CI 2.176 to 14.365,P-B＜0.008).Similarly,stratification analysis on the AA genotype demonstrated significant differences between rs17042171 and persistent AF.However,there were not significant correlations between AF and the control groups for the other 4 SNPs (P＜0.05).Conclusion:Rs17042171,near PITX2 on chromosome 4q25,is associated with AF susceptibility in the Chinese Han population from the central plains,suggesting that this SNP can provide a new strategy for clinical diagnosis in AF patients.
ABSTRACT
BACKGROUND: Hip arthroplasty has become mature, but infection after arthroplasty is a serious complication. OBJECTIVE: To analyze the clinical characteristics and treatment outcomes of infection after hip arthroplasty,thus providing reference for improving the diagnosis and treatment of postoperative infection. METHODS: A computer-based online search of CNKI, WanFang, PubMed and Medline databases from 2006 to 2016 was conducted using the keywords of "hip arthroplasty, infection" in English and Chinese, respectively. Clinical data of 20 patients with infection after hip arthroplasty in three hospitals from January 2006 to January 2016 were analyzed retrospectively. RESULTS AND CONCLUSION: (1) Two-stage revision is considered to be the main method for treating infection after hip arthroplasty. The duration of antibiotic therapy remains controversial. The increased bacterial resistance is difficult, especially the widespread use of vancomycin after hip arthroplasty.(2)Staphylococcus aureus is the highest proportion of strains detected,up to 30%,followed by 25% for staphylococcus epidermidis,20% for coagulase-negative staphylococcal and 75% for staphylococcus in the three hospitals.Gram-negative bacteria mainly contain pseudomonas aeruginosa,enterobacter cloacae and hemolytic streptococcus.(3)To conclude,antibiotics should be timely adjusted according to antibiotic susceptibility results after hip arthroplasty.
ABSTRACT
Objective To study the effect of puncture length per cubic centimeter of prostate biopsy on the detection rate of prostate cancer. Methods The clinical data of 254 prostate cancer patients who had underwent the first prostate biopsy by transrectal ultrasound guidance from September 2013 to November 2017 were retrospectively analyzed. The patients were divided into prostate cancer group and non prostate cancer group according to biopsy pathologic results. The total prostate specific antigen (TPSA), prostate volume, puncture length per needle, puncture length per cubic centimeter of prostate, volume of per needle and percentage of the sampled prostate volume were compared between 2 groups, and the relationship between puncture length per cubic centimeter of prostate and prostate cancer detection rate were analyzed. Results Among the 254 patients, the prostate cancer was in 67 cases (prostate cancer group), and the benign lesion was in 187 cases (non prostate cancer group). The prostate cancer detection rate was 26.4% (67/254). There were no statistical differences in age, puncture length per needle and volume of per needle between 2 groups (P＞0.05). The TPSA, puncture length per cubic centimeter of prostate and percentage of the sampled prostate volume in prostate cancer group were significantly higher than those in non prostate cancer group: (13.8 ± 6.8)×103 ng/L vs. (8.5 ± 3.9)×103 ng/L, (3.42 ± 0.12) mm/cm3 vs. (2.83 ± 0.18) mm/cm3 and (2.75 ± 0.31)% vs. (2.24 ± 0.25)%, the prostate volume was significantly lower than that in non prostate cancer group: (45.8 ± 15.5) cm3vs. (56.3 ± 13.8) cm3, and there were statistical differences (P＜0.05). Receiver operating characteristic curve analysis showed that area under the curve was 0.628, 95% CI 0.561 to 0.695. The cutoff value of puncture length per cubic centimeter of prostate was 3.40 mm/cm3, with the sensitivity of 59.8% and the specificity of 64.8% . Conclusions The puncture length per cubic centimeter of prostate and percentage of the sampled prostate volume are important morphometric parameters in the determination of prostate cancer. The detection rate of prostate cancer is the highest , when puncture length per cubic centimeter of prostate is≥3.40 mm/cm3.
ABSTRACT
Objective To evaluate and compare the effectivity and safety of mini-percutaneous nephrolithotomy (mPNL) and flexible ureteroscopic lithotripsy (FURL) for diameter 10 to 20 mm renal stone in obese patients. Methods This was a multicenter prospective study. One hundred and ten obese patients (body mass index≥28.0 kg/m2) with diameter 10 to 20 mm kidney stone from January 2015 to May 2017 were selected. The patients were divided into mPNL group (58 cases) and FURL group (52 cases) according to the patients′ will. The operation time, hospitalization time, complication, one-stage stone removal rate and ultimate stone removal rate were compared between 2 groups. Results The operation time, hospitalization time and incidence of complication in FURL group were significantly lower than those in mPNL group: (66.7 ± 21.9) min vs. (85.7 ± 33.4) min, (72.5 ± 23.7) h vs. (120.8 ± 33.5) h and 9.6% (5/52) vs. 31.0% (18/58), and there were statistical differences (P＜0.05). There were no statistical differences in the one-stage stone removal rate and ultimate stone removal rate between 2 groups (P＞0.05). In aspect of postoperative bleeding, hemoglobin decreased after operation (15.8 ± 9.7) g/L in mPNL group; no hemorrhage occurred in FURL group, and no significant changes in hemoglobin were observed before and after operation. Conclusions Both mPNL and FURL achieve satisfactory stone-free rates in obese patients with diameter 10 to 20 mm renal stone. Compared with mPNL, FURL has shorter operation time and lower incidence of complication.

(3) Imaging evaluation: The anterior vertebral height and vertebral height at middle line for 31 patients at 3 days, 3 months and 12 months after the surgery were higher compared to the preoperative data (P < 0.05), and Cobb angles were significantly lowered compared to the preoperative data (P < 0.05). (4) Adverse reaction: There was no leakage of bone cement in the vertebral canal and vein, and no adverse reaction occurred related to bone cement. In summary, the kyphoplasty with polymethylmethacrylate bone cement is safe and effective in treating Kummell disease in the elderly. It can fast relieve pain, improve patients quality of life, and reconstruct the spinal stability.
ABSTRACT
Objective To observe clinical efficacy of Qilin Pills combined with Three-Spot Caressing in the treatment of acquired non-consolidated kidney qi premature ejaculation (PE). Methods Totally 129 acquired non-consolidated kidney qi PE patients were randomly divided into TCM group, Fangzhognshu group and combination group. TCM group was given Qilin Pills, 6 g each time, three times a day, orally. Fangzhognshu group was guided to conduct Three-spot Caressing during sexual intercourse, no less than twice a week. Combination group was given Qilin Pills and Three-spot Caressing with the same method as Fangzhognshu group. The treatment course for each group lasted for 8 weeks. Before and after treatment of 4 weeks, 8 weeks and 4 weeks after with drawal, the intravaginal ejaculatory latency time (IELT), Chinese Index of Sexual Function for Premature Ejaculation-5 (PECI-5) scores and TCM syndrome scores (TCMS) were compared. Results Compared with before treatment, IELT increased in three groups at different time points after treatment (P<0.05). In the combination group, IELT was superior to the other two groups (except for TCM group after 4-week treatment), with statistical significance (P<0.05). Compared with before treatment, PECI-5 scores improved in three groups (except for Q6 and Q7 in Fangzhongshu group after 4-week treatment) at different time point after treatment (P<0.05). The improvement of Q5, Q6 and Q7 scores in PECI-5 of combination group was significantly better than that in the other two groups at 8-week treatment and 4-week after treatment (P<0.05). Compared with before treatment, TCMS in TCM group and combination group were improved significantly (P<0.05), PE and loss of libido score improved significantly in Fangzhongshu group (P<0.05);mental malaise and move spontaneous perspiration were significantly improved at 8-week treatment and 4 weeks after treatment (P<0.05). The improvement in TCMS was significantly better in combination group than that in the other two groups at 8-week treatment and 4 weeks after treatment (P<0.05). Conclusion Qilin Pills combined with Three-Spot Caressing has definite and long-term efficay for the treatment of acquired non-consolidated kidney qi PE.
