OBJECTIVE To investigate DNA hypermethylation of human 8-hydroxyguanine glycosy-lase(hOGG1 )gene and and the level of oxidative stress and DNA oxidative damage relations with arse-nic poisoning.METHODS In ende mic coal-pollution-borne arsenism area,Xinren county,Guizhou Province,according to the diagnostic criteria of ende mic arsenism(WS /T21 1 -2001 ),207 people with ende mic arsenism were selected and divided into four groups(The arsenic exposure group:46 cases, mild arsenism group:46 cases,moderate arsenism group:60 cases and severe arsenism group:55 cases).64 residents were selected as controls in a village about 12 km away fro m the ende mic arsenism area.With the informed consent principle,peripheral blood of all respondents was collected in order to analyze DNA methylation.Methylation-specific poly merase chain reaction were respectively performed to analyze hOGG1 Hypermethylation in arsenism respondents.Che mical methods were performed on the activity of super oxide dis mutase (SOD)and glutathione peroxidase (GSH-Px),while the contents of malondialdehyde (MDA)in the blood of patients were measured,and the contents of 8-hydroxy-2′-deox-yguanine(8-OHdG)urine of patients were measured and analysed.On the basis of methylation status are divided into hOGG1 gene methylation group (34 cases)and hOGG1 gene no methylation group (237cases).Analysis was performd on hOGG1 gene DNA methylation and the relationship between oxi-dative stress and arsenic poisoning.RESULTS The positive rates of hypermethylation of hOGG1 were associated with the degree of arsenic poisonin (co mpared with control group,χ2 =23.916,P <0.05, Co mpared with the Ende mic area normal group,χ2 =12.039,P <0.05 ).Co mparing with negative group,SOD〔(85 ±25)kU·L -1 〕,GSH-Px〔(70 ±26)kU·L -1 〕activity and 8-OHdG 〔(22.5 ±6.8)μg·L -1 〕contents were lower〔(1 18 ±41 )kU·L -1 ,(171 ±56)kU·L -1 ,(28.4 ±6.5)μg·L -1 ,P <0.05)〕in positive group.There was no significant difference between the MDA content(P>0.05).CONCLUSION Coal arsenic exposure can cause hOGG1 gene high methylation and oxidation and anti-oxidation system imbalance,causing DNA oxidative damage,it is one of the reasons to pro mote the develop ment of arsenic poisoning occurred.

Abstract: Objective　To analyze the drug sensitivity and the carrying of carbapenem resistant gene of Acinetobacter baumannii isolated from clinical patients and clinical objects, and analyze the homology of strains to provide support for the control of nosocomial infection. Methods　A total of 38 strains of Acinetobacter baumannii isolated from patients and clinical objects surface were collected from January 2019 to August 2020. The antimicrobial susceptibility was tested by the minimum inhibitory concentration method. In addition, the resistance related genes were detected by polymerase chain reaction method, and homology analysis was performed by enterobacterial repetitive Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction (ERIC-PCR). Results All 34 strains of Acinetobacter baumannii isolated from Clinical patients and 4 strains isolated from clinical objects carried blaOXA-51 and imp resistance genes, neither of them carried blaVIM gene. 32 Acinetobacter baumannii carrying blaOXA-23 gene, 28 strains carrying blaTEM gene, 7 strains carrying blaOXA-58 gene. After cluster analysis, 38 Acinetobacter baumannii isolates were classified into 7 genotypes (expressed A, B, C, D, E, F, G), and cluster E and cluster G were the main clusters, containing 12 strains (12/38, 31.6%) and 18 strains (18/38, 47.4%), respectively, as the main prevalent clonal strains. Conclusions　Acinetobacter baumannii isolated from different sources have the significant differences in drug resistance and carry different resistance genes. There is no direct correlation between patients and environmental isolates of Acinetobacter baumannii belonging to different clonal strains. Also, there aren’t significant correlation between clinical patients infected with Acinetobacter baumannii.

OBJECTIVETo evaluate the efficacy and safety of Jinying Capsule (JC) in treating pelvic inflammatory disease patients with accumulated damp-heat syndrome (ADHS).

METHODSTotally 328 patients were recruited in a prospective, positive drug parallel controlled, and multi-center clinical trial. Of them 213 patients in the treatment group took JC (0.5 g per capsule), 4 capsules each time, 3 times per day, while 115 patients in the control group took Kangfuyan Capsule (KC, 0.4 g per capsule), 3 capsules each time, twice per day. The course of treatment was 4 weeks for all. Scores of Chinese medical syndromes, visual analogue scale (VAS) of the lower abdominal pain, and European quality of life-five dimension scale (EQ-5D) were observed before treatment and after 4 weeks of treatment.

RESULTSThere were 204 patients in the treatment group and 109 in the control group who completed this trial. The total effective rate of Chinese medical syndrome was 89.71% (183/204 cases) in the treatment group and 76.15% (83/109 cases) in the control group (P < 0.01). Compared with before treatment in the same group, EQ-5D scores increased, and VAS scores of the lower abdominal pain decreased in the two groups after treatment. EQ-5D scores was 0.857 ± 0.157 in the treatment group, obviously higher than that in the control group (0.753 ± 0.126, P < 0.05). VAS scores of the lower abdominal pain was 2.14 ± 1.23 in the treatment group, lower than that in the control group (2.33 ± 1.24), but with no statistical difference between the two groups (P > 0.05). No adverse reaction occurred in the two groups.

CONCLUSIONJC was superior to KC in improving Chinese medical syndrome and quality of life of pelvic inflammatory disease patients with accumulated damp-heat syndrome.

Objective To investigate the effect of insulin on D_5 dopamine receptor expression and function in renal proximal tubule (RPT).Methods Immortalized RPT cells and D_5 receptor transfected HEK293 (HEK-D_5) cells were used in the study to investigate the effect of insulin on D_5 receptor expression and function,and those effects were compared in RPT cells from Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHR). The function of D_5 receptor was determined by measurement of the Na~+-K~+-ATPase activity in HEK-D_5 cells. Results Insulin increased D_5 receptor protein expression in a concentration and time-dependent manner in WKY RPT cells,but not in SHR.The basal level of D_5 receptor expression was higher in WKY cells than that in SHR cells. Stimulation with fenoldopam(D_1-like dopamine receptor agonist) inhibited the Na~+-K~+-ATPase activity;pretreat- ment with insulin increased the inhibitory effect of fenoldopam on Na~+-K~+-ATPase activity in HEK-D_5 cells. Conclusion The abnormal regulation of insulin on D_5 receptor expression and function might be involved in the path- ogenesis of essential hypertension.

Objective To explore the extent of lung injury induced by hyperoxia,and the activity of ubiquitin-proteasome pathway(UPP) in pathophysiological progress of lung tissue in early stages.Methods Adopted completely random design,20 SD rats were divided into hyperoxia group and air control group.For the air control group,the oxygen concentration exiting the cages was analyzed with oxygen monitor and oxygen concentration remained at 210 mL/L for 72 hours;while in the hyperoxia group,the condition changed into high-density oxygen(950 mL/L) for 72 hours to estimate the hyperoxia lung injury in rats model.The contents linked morphology as pathological classification in gross finding,pathological score of lung injury and the index of pneumonedema-the ratio of moist to dry weight of lungs were mea-sured.The expressions of ubiquitin protein and the activity of proteasome 20 S and the active statement of ubiquitin-proteasome pathway were detected by immunohistochemistry and Western blot methods.Results 1.The hyperoxia lung injury rat model was successfully duplicated.2.In hyperoxia group,pulmonary edema with increased ratio of moist to dry weight of lungs could be found(P=0).3.Macroscopic observation: bright red and full-stacked lung tissue,foliated or local hemorrhage on the surface,but little pleural effusion was observed in hyperoxia group.There was statistical significance of pathological classification in gross finding between hyperoxia group and air control group(P=0.005).Light microscope observation:swelled alveolar epithelium,widened alveoli wall,capillary engorgement and telangiectasis,obvious edema in interstitial tissue of pulmonary aveolus and alveolar space,increased inflammatory cells were observed in hyperoxia group.The findings of pathological score of lung injury indicated more serious injure than control group(P=0).4.The increased expression of ubiquitin protein in lung tissue was discoved by using immunohistochemistry and Western blot findings after hyperoxia exposure 72 hours.(P=0).5.The acti-vity of proteasomes 20 S in hyperoxia group was higher than that in control group(P=0).Conclusions The mainly pathological changes of lung are generated through hyperoxic exposure for 72 hours,including alveolar epithelial cell and vascular endothelial cell injury diffusely,inflammatory cell infiltration and pulmonary edema.Active the ubiquitin-proteasome pathway is connected with the pathophysiological process of lung injury in the initial stages of hyperoxia-exposure.
