Objective To determine the distribution and antibiotics resistance characteristic of pathogens in urinary tract infections in aged female diabetics patients and provide scientific basis for clinicians in selecting effective antibiotics. Methods Pathogenic bacteria, isolated from specimens of 107 elderly female diabetic cases with urinary tract infections, were identified and drug susceptibility tests were performed by VITEK-32 analysator. Results Among all 107 kinds of isolated bacteria,the ratio of gram-negative bacteria was 74. 8% ( 80/107 ), predominated by Escherichiacoli ( accounting for 48. 6% [52/107] ); the ratio of gramposition bacterias was 13. 1% (14/107) and eumycetes was 12. 1% (13/107). In antibiotic resistance analysis,the gram negative bacteria showed higher drug-resistance to the some common-antibiotics, such as ampicililin,cefazolin,cefuroxime-sodium and cefuroxime axetil ( ＞ 70. 0% ), while they were sensitive to imipenem and amikacin( ＜ 10. 0% ). The gram positive bacteria were most sensitive to vancomycin (0%), followed by Linezolid(7.7% ). Conclusion Escherichiacoli were the major pathogenic bacteria in urinary tract infections in aged female diabetic patients, with higher drug resistance. Therefore, drug resistance monitoring should be carried out according to the variety of pathogenic bacteria so as to guide rational use of antibiotics and decrease drug resistance.

Objective To analyse the effects of the lung recruitment manoeuvre(RM)mode implemented by ICU specialist nurses on remission of the patients with acute respiratory distress syndrome(ARDS),with the aim to explore the safety,feasibility and effectiveness of clinical implementation,and to further provide a new mode for patient management in nursing practice.Methods A total of 40 ARDS patients admitted into the ICU from January 2018 to August 2021 were randomly selected and divided into control group and trial group in equal number with a random number table.Patients in the control group was treated with a conventional RM mode implemented by doctors,and the RM mode implemented by the ICU specialist nurses was applied to the patients in trial group.The indexes of arterial blood gas analysis,mechanical ventilation time,length of ICU stay,number of RM,number of adjustments to a RM plan,and complication rate were compared between the two groups after the second RM implementation.Results There was no statistically significant difference in arterial partial pressure of oxygen,arterial partial pressure of carbon dioxide and oxygenation index between the groups at 1h and 24h after the second RM implementation(P>0.05).There was no statistically significant difference in the number of RM,mechanical ventilation and length of ICU stay between the groups(P>0.05).The number of modifications of the RM plan in the trial group was significantly more than that in the control group(P<0.05).There was no complication of RM in both groups.Conclusions The RM mode implemented by ICU specialist nurses could achieve good clinical effects in the treatment of patients with ARDS. The approach is safe and practicable.

Objective To explore the effect of intraoperative parathyroid hormone (IOPTH) examination on parathyroidectomy for primary hyperparathyroidism.Methods The clinical data of 41 PHPT patients who received IOPTH monitoring (IOPTH group) from Jan.2009 to Dec.2014 were retrospectively analyzed.The clinical manifestation,examination and changes of parathyroid hormone and calcium before and after operation were collected.Results There were 12 males and 29 females.36 cases had parathyroid adenoma,and 5 cases were parathyroid carcinoma.23 cases were positive in 24 cases of 99Icm-MIBI parathyroid adenoma radionuclide examination,and 2 cases were positive in 3 cases of parathyroid carcinoma radionuclide 99Tcm-MIBI inspection (P＝ 0.213).10 mins after tumor resection,PTH in all cases decreased by 50％ or more than that before tumor resection except for one case of parathyroid carcinoma.23 cases appeared hypocalcemia in 36 cases of parathyroid adenoma after surgery and 2 cases appeared hypocalcemia in 5 cases of parathyroid cancer patients (P＝0.361).No postoperative hoarseness,cough,bleeding occoured.Patients were followed up from 6 to 72 months.Hypocalcemia symptoms recovered 2 weeks to 3 months after surgery.No permanent hypoparathyroidism occured.One case of parathyroid carcinoma died of hypercalcemia 5 months after surgery.The remaining 40 cases survived without recurrence or death.Conclusions Intraoperative PTH monitoring can help doctors analyze whether all the hyperthyroidism glands have been removed,which can help to avoid miss diagnosis of multiple gland disease and unnecessary bilateral neck exploration.This method is highly accurate so it is recommended for routine use in PHPT surgery.

OBJECTIVEThe main purpose of this work was to give the evidence of reasonable and feasible dust control measures which will be taken in the future by analyzing the trend of dust concentration from 1991 to 2010 and identifying working faces with the severe dust contamination in one underground iron mine.

METHODSThe data was from routine monitoring between the years 1991 and 2010, which enclosed the total dust concentrations and silica contents. China National Standard of Occupational exposure limits for hazardous agents in the workplace used to judge whether the dust concentration exceeded the National Standard.

RESULTSThe general trend of total dust concentration from 1991 to 2010 was decreased, especially maximum and average levels. The highest exceeding rate was 43.16% in 1993 and the best years were 2009 and 2010, but the exceeding rates were still over 30%. The dust exposure levels varied with different work faces. The mining and supporting were the most severe dust pollution faces which the highest ultra exceeding rates were 51.61% and 51.48% and the maximum exceeding times were 64.6 and 16.4 respectively. The next was constructing face with 40.23% exceeding rate and 24.6 times more than standard.

CONCLUSIONThe trend of total dust concentration from 1991 to 2010 was decreased, but the dust exceeding rate was still high. The strong measures should be taken to control the dust pollution in this iron mine, especially mining and supporting faces.

Objective     To explore the association between the preoperative systemic immune-inflammation index (SII) and prognosis in non-small cell lung cancer (NSCLC) patients. Methods     A comprehensive literature survey was performed on PubMed, Web of Science, EMbase, The Cochrane Library, Wanfang, and CNKI databases to search the related studies from inception to December 2021. The hazard ratio (HR) and 95% confidence interval (CI) were combined to evaluate the correlation of the preoperative SII with overall survival (OS), disease-free survival (DFS), and recurrence-free survival (RFS) in NSCLC patients. Results     A total of 11 studies involving 9 180 patients were eventually included. The combined analysis showed that high SII levels were significantly associated with worse OS (HR=1.61, 95%CI 1.36-1.90, P<0.001), DFS (HR=1.50, 95%CI 1.34-1.68, P<0.001), and RFS (HR=1.17, 95%CI 1.04-1.33, P<0.001). Subgroup analyses also further verified the above results. Conclusion     Preoperative SII is a powerful prognostic biomarker for predicting outcome in patients with operable NSCLC and contribute to prognosis evaluation and treatment strategy formulation. However, more well-designed and prospective studies are warranted to verify our findings.

OBJECTIVES: To explore the relevant protective and risk factors that affect spontaneous supratentorial large volume intracerebral hemorrhage. METHODS: Clinical data of hospitalized patients with spontaneous supratentorial intracerebral hemorrhage in Xiangya Hospital of Central South University from January 2014 to December 2018 were retrospectively analyzed. According to the amount of intracerebral hemorrhage (≥30 mL), the patients were divided into a large volume intracerebral hemorrhage group (255 cases) and a non-large volume intracerebral hemorrhage group (397 cases). Univariate and multivariate logistic regression analysis for the clinical data from the two groups of patients were performed. RESULTS: Systolic blood pressure, diastolic blood pressure, white blood cell count, neutrophil count, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein cholesterol, calcium ion concentration, and international standard ratio between the large volume intracerebral hemorrhage group and the non-large volume intracerebral hemorrhage group were significantly different (all CONCLUSIONS The occurrence of spontaneous supratentorial large volume intracerebral hemorrhage is the result of combination of multiple factors. The increased white blood cell count, the increased systolic blood pressure, the increased high-density lipoprotein cholesterol, and the increased international standard ratio may increase its risk, while the increased LDL cholesterol and calcium concentration may reduce its risk.

To evaluate the safety and effectiveness of Shenbei Guchang capsules in treatment of diarrhea type irritable bowel syndrome (yang deficiency of spleen and kidney) under widely used conditions, an open, multicenter, controlled, phase Ⅳ clinical trial was conducted in the drug clinical trial centers of 16 domestic hospitals. 2 123 patients from June 10, 2011 to November 29, 2012 were enrolled in the trial. Drug clinical trial was approved by Sichuan Academy of Medical Sciences, Sichuan Provincial People's Hospital Ethics Committee before implementation. Before the start of trial, subjects were selected according to the research scheme and inclusion criteria, then they would step into the 14 d study after signing Informed Consent Form. All subjects were treated according to the research scheme, evaluated the conditions and filled in CFR sheet, to provide the evaluation data and information on safety and efficacy of Shenbei Guchang capsules. Shenbei Guchang capsules were used to treat diarrhea type irritable bowel syndrome in widely used conditions (2 123 cases), and 2 029 cases of them entered FAS set, cure+markedly effective in 1 921 cases, with a comprehensive curative effect rate of 94.68%; 2 010 cases of them entered PPS set, cure+markedly effective in 1 906 cases, with a comprehensive curative effect rate of 94.83%. The primary symptoms of IBS were abdominal pain and diarrhea. After treatment, both abdominal pain and diarrhea were improved, with significant differences (P<0.000 1). There were significant differences in traditional Chinese medicine symptom scores on both post-treatment day 7 and day 14 as compared with the conditions before treatment (P<0.000 1). 35 cases of adverse events occurred during the trial with an incidence of 1.65%, including 12 cases of drug-related adverse events (adverse reaction) with an incidence of 0.57%, mainly manifested as nausea, abdominal distension and dry mouth, most of which would be spontaneously relieved without any measures. No serious adverse events occurred. The commercially available Shenbei Guchang capsules are proved safe and effective for the treatment of diarrhea type irritable bowel syndrome (yang deficiency of spleen and kidney) under widely used conditions (2 123 cases), and can be continued for clinical promotion and application.

OBJECTIVE To explore the the reg ulation of intestinal flora and effects of Qingjie huagong decoction on intestinal mucosal barrier in severe acute pancreatitis （SAP）mode rats . METHODS SAP rat model was induced by intraperitoneal injection of caerulein and lipopolysaccharide.The survival state of rats in each group were observed.The levels of serum amylase ，interleukin 10（IL-10），IL-18 and IL- 1β in serum were all detected. The pathological changes of pancreatic and small intestinal tissue were observed. The expressions of Occludin，ZO-1 and HMGB1 were detected in small intestinal tissue of rats. The structure and relative abundance of intestinal microflora in rats were detected by 16S rRNA high throughput sequencing. RESULTS After the intervention of Qingjie huagong decoction ，abdominal distension symptoms of SAP model rats were significantly relieved ，and their mental state recovered better ；the levels of serum amylase and IL- 18 in serum were decreased significantly （P＜0.05），while the level of IL- 10 was increased significantly （P＜0.05）. The necrotic area of pancreatic tissue and the infiltration of inflammatory cells were reduced ， the degree of intestinal epithelial cell structural disorder was alleviated ，and the shedding of intestinal mucosal epithelium was reduced.The protein expression of HMGB 1 in small intestinal tissue was decreased significantly （P＜0.05），and the protein expression of Occludin and ZO- 1 were increased significantly . Results of 16S rRNA high throughput sequencing showed that Qingjie huagong decoction could increased the relative abundance of probiotics such as Bacteroidea and Lactobacillus in rat intestine ，reduced the colonization of harmful bacteria such as Firmicutes. CONCLUSIONS Qingjie huagong decoction can improve the intestinal barrier by up-regulating the expression of Occludin and ZO- 1 in small intestinal tissue and down-regulating the protein expression of HMGB 1. It can also adjust the relative abundances of different flora to protect the intestinal tract.

OBJECTIVES: Safe and effective anticoagulation is essential for hemodialysis patients who are at high risk of bleeding. The purpose of this trial is to evaluate the effectiveness and safety of two-stage regional citrate anticoagulation (RCA) combined with sequential anticoagulation and standard calcium-containing dialysate in intermittent hemodialysis (IHD) treatment. METHODS: Patients at high risk of bleeding who underwent IHD from September 2019 to May 2021 were prospectively enrolled in 13 blood purification centers of nephrology departments, and were randomly divided into RCA group and saline flushing group. In the RCA group, 0.04 g/mL sodium citrate was infused from the start of the dialysis line during blood draining and at the venous expansion chamber. The sodium citrate was stopped after 3 h of dialysis, which was changed to sequential dialysis without anticoagulant. The hazard ratios for coagulation were according to baseline. RESULTS: A total of 159 patients and 208 sessions were enrolled, including RCA group (80 patients, 110 sessions) and saline flushing group (79 patients, 98 sessions). The incidence of severe coagulation events of extracorporeal circulation in the RCA group was significantly lower than that in the saline flushing group (3.64% vs. 20.41%, P<0.001). The survival time of the filter pipeline in the RCA group was significantly longer than that in the saline flushing group ((238.34±9.33) min vs. (221.73±34.10) min, P<0.001). The urea clearance index (Kt/V) in the RCA group was similar to that in the saline flushing group with no statistically significant difference (1.12±0.34 vs. 1.08±0.34, P=0.41). CONCLUSIONS Compared with saline flushing, the two-stage RCA combined with a sequential anticoagulation strategy significantly reduced extracorporeal circulation clotting events and prolonged the dialysis time without serious adverse events.
