According to the Global Antimicrobial Resistance and Use Surveillance System (GLASS) data, antibiotic resistance escalates more challenges in treatment against communicable diseases worldwide. Henceforth, the use of combinational antimicrobial therapy and metal-conjugated phytoconstituents composites are considered as alternatives. The present study explored the efficacy of mercuric-sulfide-based metallopharmaceutical, Sivanar Amirtham for anti-bacterial, anti-tuberculosis, anti-HIV therapeutics and toxicity profile by haemolytic assay, first of its kind. The anti-bacterial study was performed against both gram-positive and gram-negative pathogens including Staphylococcus aureus (ATCC 29213), Methicillin-resistant Staphylococcus aureus (MRSA: ATCC 43300), Enterococcus faecalis (ATCC 29212), Pseudomonas aeruginosa (PA14) and Vibrio cholerae (MTCC 3905) by agar well diffusion assay, wherein the highest zone of inhibition was identified for MRSA (20.7 mm) and V. cholerae (34.3 mm) at 25 mg/mL. Furthermore, the anti-tuberculosis activity experimented by microtitre alamar blue assay against M. tuberculosis (ATCC 27294) demonstrated significant activity at the concentration range of 12.5-100 µg/mL. Additionally, the anti-HIV efficacy established by the syncytia inhibition method using C8166 cell lines infected with HIV-1IIIB, showed a significant therapeutic effect. The in-vitro toxicity assay proved Sivanar Amirtham to be non-haemolytic and haemocompatible. The physicochemical characterization studies revealed the nano-sized particles with different functional groups and the distinctive metal-mineral complex could be attributed to the multi-site targeting ability. The rationale evidence and scientific validation for the efficacy of Sivanar Amirtham ensures that it could be proposed as an alternative or adjuvant for both prophylactics and therapeutics to overcome HIV infection and antimicrobial resistance as well as the multi-drug resistance challenges.

Coronavirus Disease-2019 (COVID-19) has been a major public health issue all over the world, placing a significant burden on available healthcare resources. The most common types of COVID-19 are the mild and common forms. Although the proportion of the severe-critical types is smaller, the rate of death is significantly higher and the medical resources required tend to be greater. Thus, a variety of scores based on other disease and COVID-19 were used to assess the risk of poor prognosis on the COVID-19, including the common scores for community-acquired pneumonia, sepsis and viral pneumonia. Unfortunately, the above scores often lacked an adequate description of the applicable population or were at high risk of bias with unknown applicability. Therefore, the article summarized the existing scores, aiming to provide a reference for clinical prognostic risk assessment.

OBJECTIVES: Infectious Zika viral particles were detected in human milk; however, whether they can be transmitted via breastfeeding remains unknown, so our objective was to clarify this. METHODS: Here, in a natural breastfeeding model, wild-type (C57Bl/6; WT) or interferon α/ß (IFNα/ß) receptor-deficient (A129; KO) murine dams on day 1 post-delivery were infected with Zika virus (ZIKV) intraperitoneally, and the neonates were suckled. In a novel artificial feeding model, WT suckling mice at 1 day old were fed with ZIKV alone or ZIKV and human breast milk mixtures. Thereafter, the virus distribution, clinical progression and neuropathology in the WT or KO neonates were characterized to evaluate the risk of ZIKV transmission through breast milk. RESULTS: In natural breastfeeding, viral RNAs (8/8) and infectious viral particles (7/8) were extensively present in the mammary glands of KO dams. All tested KO neonates (5/5), and none of WT neonates (0/9), were infected with ZIKV. In artificial feeding, 100% of the WT neonates (two groups, 12/12 and 16/16) were infected and developed some signs of neurodegeneration. ZIKV tended to seed and accumulate in the lungs and were subsequently disseminated to other tissues in both 16 naturally suckled and 19 artificially fed infected neonates. As human breast milk was mixed with ZIKV and fed to WT neonates, 45% individuals (9/20) were infected; in the infected neonates, the viral spread to the brain was delayed, and the clinical outcomes were alleviated. CONCLUSIONS: These results demonstrated that suckling mice can be infected with ZIKV through suckling, and breast milk has potential antiviral activity, inhibiting ZIKV infection.

Objective: To investigate the clinical and pathological features and prognosis of white lesion of vocal cord. Methods: One hundred and fifty-four cases of white lesion of vocal cord from January 2009 to February 2016 were retrospectively analysed. All the patients had undergone the resection of white lesion of vocal cord resection through retaining laryngoscope under general anesthesia with the specimens pathologically examined. Results: There were 148 males and 6 females in this study. The ages ranged from 36 to 83 years, and the median age was 54.5.There were 103(66.88%) long-term smokers, and 64(41.56%) long-term drinkers. Postoperative pathology showed that chronic mucosal inflammation in 19 cases (12.34%), squamous epithelial hyperplasia in 56 cases(36.36%), mild dysplasia in 25 cases(16.23%), moderate dysplasia in 34 cases(22.08%), severe dysplasia in 12 cases(7.79%), carcinoma in situ in 6 cases(3.90%), and invasive carcinoma in 2 cases(1.30%). The recurrence rate and canceration rate of chronic mucosal inflammation were 0. The recurrence rate of squamous epithelial hyperplasia was 10.71%, the canceration rate was 0.The recurrence rate of mild dysplasia was 8.00%, the canceration rate was 0. The recurrence rate of moderate dysplasia was 20.59%, the canceration rate was 8.82%. The recurrence rate of severe dysplasia was 25.00%, the canceration rate was 16.67%. Conclusions: White lesion of vocal cord is a predominantly male disease. Long-term smokering and drinking are one of common causes. The final diagnosis of white lesion of vocal cord relies on the pathology. Closed observation is necessary for theses dysplasia cases. The majority of which are benign, the operation effect is good.

Objective:Anti-reflux medications or botulinum toxin A injections are the main current therapies for the definite vocal process granuloma. This studies is focusing on comparing the effects of proton pump inhibitors plus prokinetic agents with botulinum toxin A injections on vocal process granuloma. Method:Adult patients in our outpatient department (from December 2014 to June 2016) complaining of trachyphonia and/or abnormal pharyngeal sensations who were found to have contact granulomas (38 cases) were included. Patients were divided into two groups according to the treatment selected by themselves: esomeprazole with mosapride citrate (n=28) or botulinum toxin A injection (n=20). The reflux symptom index and reflux finding score determined by electronic fibrolaryngoscopy were utilized to assess efficacy. Result:There was no statistical difference on age, sex and reflux symptom index and reflux finding score before treatment between the two groups. Total effective rate in the esomeprazole with mosapride citrate group and the botulinum toxin A group were 96.43% and 45.00%, separately. The recorded symptoms after therapy resolved with a statistically significant improvement in the esomeprazole with mosapride citrate group. Conclusion:Combined proton pump inhibitor plus prokinetic drug therapy plays a significant role in the treatment of vocal process granulomas.

Objective:To investigate the prevalence of voice disorder and quality of life in the primary school teachers in a certain district of Chengduand examine the correlation between two voice-specific questionnaires.Method:Random sampling survey included 389 teachers from a certain district of Chengdu.Twelve item general health questionnaire(GHQ-12),voice handicap index 10(VHI-10) and voice-related quality of life (V-RQOL) were investigated and routine examination of throat with electronic fiber laryngoscopy were carried out for teachers.Result:There were 189 teachers who had voice disorders(voice disorders group),and 200 teachers who did not have voice disorders(control group).â¡The total score's difference of V-RQOL and VHI-10,functional(F) and emotion(E) dimensions in VHI-10 between two groups were statistically significant(P<0.05),however,there were no statistically significant difference of GHQ-12 between two groups. The total score of GHQ-12 was positively correlated with VHI-10(r=0.194,P <0.05),while the total score of V-RQOL was negatively correlated with GHQ-12(r=-0.209,P<0.05) and VHI-10 (r=-0.586, P <0.05).Conclusion:Voice disorders can affect teachers' psychology and voice related quality of life.Although the VHI-10 and V-RQOL had correlation,the correlation is not strong.So it is recommended combine VHI-10 and V-RQOL when the quality of life of voice disorders is evaluated.
RESUMO
This study investigated the absorption mechanism of ginsenoside Rh2 to clarify the reasons for its poor absorption. Transepithelial transport across Caco-2 cell monolayers, cellular uptake, and in situ rat intestinal perfusion were examined. Cellular uptake of Rh2 was linear from 1 to 50 µM at 4°C, whereas it was saturated when the concentration exceeded 10 µM at 37°C. At 37°C, the uptake at 10 µM was linear in 60 min. Intracellular exposure in 240 min was 2173.70 and 979.38 ng·min/µg for S and R isomers, respectively. Transepithelial permeability of Rh2 was about 10â»8 to 10â»7 cm/s. Efflux ratios were above 1.5. Sodium dodecyl sulfate, sodium citrate, and sodium deoxycholate had no effect on Rh2 permeability. After intestinal perfusion for 3 h, 9.1% of 20(R)-Rh2 and 15.7% of 20(S)-Rh2 were absorbed. Cyclosporine, quercetin, and probenecid could improve the cellular uptake, absorptive permeability, and intestinal absorption. Carrier-mediated transport was the major absorption mechanism. Rh2 was a substrate of ABC transporters. The ABC-transporter-mediated efflux and the poor permeability were the major reasons for Rh2 poor absorption. The stereoselective absorption was significant. R isomer exhibited lower absorption profiles in all the experiments, possibly due to more potent efflux.

The aim of this study was to investigate the effects of maternal lead exposure on the learning and memory ability and expression of tau protein phosphorylation (P-tau) and beta amyloid protein (Abeta) in hippocampus of mice offspring. Pb exposure initiated from beginning of gestation to weaning. Pb acetate administered in drinking solutions was dissolved in distilled deionized water at the concentrations of 0.1%, 0.5% and 1% groups. On the 21 th of postnatal day, the learning and memory ability of the mouse pups was tested by Water Maze test and the Pb levels in blood and hippocampus of the offspring were also determined. The expression of P-tau and Abeta in hippocampus was measured by immunohistochemistry and Western blotting. The Pb levels in blood and hippocampus of all exposure groups were significantly higher than that of the control group ( P < 0.05). In Water Maze test, the performances of 0.5% and 1% groups were worse than that of the control group ( P < 0.05). The expression of P-tau and Abeta was increased in Pb exposed groups than that of the control group ( P < 0.05). Tau hyper-phosphorylation and Abeta increase in the hippocampus of pups may contribute to the impairment of learning and memory associated with maternal Pb exposure.
