To investigate the efficacy and safety of cold snare endoscopic mucosal resection (CS-EMR) and hot snare endoscopic mucosal resection (HS-EMR) for colorectal polyps with diameters of 6-9 mm. Retrospective analysis was performed on the clinical data of 485 patients with colorectal polyps (6-9 mm in size) who were treated with CS-EMR or HS-EMR in the endoscopy center of Hangzhou Third People's Hospital from January 2017 to December 2019. Colorectal polyps were lifted by submucosal injection of normal saline.

Role of Eradication in Chronic Spontaneous Urticaria: A Propensity Score Matching Analysis.

Objective: To investigate the role of (HP) eradication in chronic spontaneous urticaria (CSU) treatment.

Methods: Retrospective analysis was performed on the clinical data of 522 patients with CSU who underwent a HP breath test in Hangzhou Third People's Hospital between January 2018 and December 2019. The CSU-HP(+) group consisted of patients with CSU and HP infection, who were treated with antihistamines combined with HP eradication therapy.

Oesophageal ulceration in adult patients treated with doxycycline for acne vulgaris.

Objective: To report drug-induced oesophageal ulceration in adult patients treated with doxycycline for acne vulgaris.

Methods: This retrospective case series included data from adult patients treated with oral doxycycline therapy for acne vulgaris, who had presented with oesophageal ulceration at the Third People’s Hospital of Hangzhou between June 2016 and December 2017, and whose diagnosis was confirmed by gastroscopy. Clinicodemographic data were analysed, including symptom onset, endoscopy results, that were assessed for classic features of oesophageal ulceration.

Microbial community evolution and fate of antibiotic resistance genes in anammox process under oxytetracycline and sulfamethoxazole stresses.

The microbial community characteristics, functional and antibiotic resistance genes (ARGs), anammox performance under individual and combined oxytetracycline (OTC) and sulfamethoxazole (SMX) were tested under environmentally relevant levels. The results showed that anammox performance was inhibited when the OTC or SMX concentration increased from 0.5 to 1.

The performance and microbial community in response to MnO nanoparticles in anammox granular sludge.

The response of anaerobic ammonium oxidation (anammox) process and granular sludge in the upflow anaerobic sludge blanket reactor was analyzed under long-term exposure to MnO nanoparticles (NPs) (1-200 mg L). The addition of 200 mg L MnO NPs had a significantly positive effect on nitrogen removal and this system exhibited excellent performance, with a total nitrogen removal efficiency of 93.1%.

Effects of ZnO nanoparticles on high-rate denitrifying granular sludge and the role of phosphate in toxicity attenuation.

The increasing release of engineered nanoparticles (NPs) from consumer products has raised great concerns about their impacts on biological wastewater treatment. In this study, the widely-used ZnO NP was selected as a model NP to investigate its impact on high-rate denitrifying granular sludge in terms of sludge properties and community structure. A hormesis effect was observed during short-term exposure, in which the specific denitrification activity (SDA) was stimulated by 10% at 1 mg L ZnO NPs, but inhibited by 23% at 5.

Acetaminophen-induced acute pancreatitis: A case report and literature review.

Acute pancreatitis is rarely associated with drugs. Acetaminophen overdose is a well-known cause of hepatic toxicity, but drug-induced pancreatitis is rarely reported, especially after mild overdose. A 32-year-old woman presented with nausea and vomiting for 12 h, but no abdominal pain following an overdose of eight Tylenol tablets containing acetaminophen (325 mg acetaminophen per tablet).

Effect of chromium on granule-based anammox processes.

In this study, the feasibility of application of anaerobic ammonium oxidation (anammox) to teat wastewater containing chromium was assessed. Anammox granule activity decreased with increasing Cr(VI) concentration and pre-exposure time in batch tests, and the 50% inhibition concentration of Cr(VI) on anammox biomass was 296.5 mg L.

[Adsorption of Pb and Cd from Aqueous Solution Using Vermicompost Derived from Cow Manure and Its Biochar].

Using vermicompost (CV) as raw material, its biochar (CVC350) was prepared at 350℃ and then their physio-biochemical properties were characterized. Furthermore, adsorption studies were performed in a batch system for removing Pb and Cd ions from solution. The characterization results revealed much higher surface area, smaller pore size, greater aromaticity and nonpolarity of CVC350 as compared to CV.

[Evaluation on Heavy Metal Pollution and Its Risk in Soils from Vegetable Bases of Hangzhou].

With the purpose of investigation on heavy metal contamination in soils from vegetable bases of Hangzhou, adopting field investigation and indoor analysis methods, the contents of heavy metals as Cu, Zn, Pb, Cd, Cr, As and Ni, together with their relevance to the physicochemical properties of the 203 soils from 30 vegetable bases in 10 districts of Hangzhou were studied. The results showed that the contents of heavy metals such as Zn,Cr,As,Ni generally didn't exceed the standard, while the contents of heavy metals such as Cu, Pb, Cd exceeded it. The results from synthetic pollution evaluation showed that the soils were slightly polluted in soils from vegetable bases of Hangzhou, which were mainly caused by Cd pollution.

[Influence of Steam Killenzyme Torrefaction on Quality of Camellia nitidissima Based on Multi-index Evaluation].

Objective: To explore the influence of steam killenzyme torrefaction on the quality of Camellia nitidissima.

Methods: Based on the quality evaluation index, Camellia nitidissima was processed by steam killenzyme torrefaction and sun-dried. The contents of functional ingredients such as flavonoids, saponins, tea polyphenols, polysaccharides, amino acids, tea extracts, catechin and epicatechin were determined by HPLC and UV.

[Effect of Chinese drugs for strengthening Pi, harmonizing Wei, and dispersing blood stasis on the expression of gastric mucosal heat shock protein 70 in chronic atrophic gastritis patients].

Objective: To observe the effect of Chinese drugs for strengthening Pi, harmonizing Wei, and dispersing blood stasis (CDSPHWDBS) on the expression of gastric mucosal heat shock protein 70 (HSP70) in chronic atrophic gastritis (CAG) patients.

Methods: A total of 100 CAG patients were assigned to the control group and the treatment group by random digit table, 50 in each group. Patients in the control group took Folic Acid Tablet 10 mg each time, 3 times per day.

[Comparative studies on the characteristics for Cu2+ or Zn2+ adsorption onto different landfilled sludge].

In this paper, it was comparatively studied about the adsorption or desorption behaviour for Cu2+ or Zn2+ ion onto different landfilled sludge. The results showed that Cu2+ or Zn2+ adsorption isotherm could significantly conform to Freundlich and Henry equations both for the directly landfilled sludge (SSA) and the solidifying landfilled sludge (SSB). Moreover, much higher adsorption capacities were found for Cu2+ on SSA but for Zn2+ on SSB, and the removal efficiency could reach 95% for Cu2+ by SSA with dosage being 10-20 g/L or Zn2+ by SSB with dosage being 5 g/L when the initial CU2+ or Zn2+ concentration was 128 mg/L.
