Objective:To study the distribution and antibiotics resistance of the main pathogens of neonatal purulent meningitis in different regions of China.Methods:A retrospective descriptive clinical epidemiological study was conducted in children with neonatal purulent meningitis which admitted to 18 tertiary hospitals in different regions of China between January 2015 to December 2019. The test results of blood and cerebrospinal fluid, and drug sensitivity test results of the main pathogens were collected. The distributions of pathogenic bacteria in children with neonatal purulent meningitis in preterm and term infants, early and late onset infants, in Zhejiang Province and other regions outside Zhejiang Province, and in Wenzhou region and other regions of Zhejiang Province were analyzed. The chi-square test was used for statistical analysis.Results:A total of 210 neonatal purulent meningitis cases were collected. The common pathogens were Escherichia coli ( E. coli)(41.4%(87/210)) and Streptococcus agalactiae ( S. agalactiae)(27.1%(57/210)). The proportion of Gram-negative bacteria in preterm infants (77.6%(45/58)) with neonatal purulent meningitis was higher than that in term infants (47.4%(72/152)), and the difference was statistically significant ( χ2=15.54, P=0.001). There were no significant differences in the constituent ratios of E. coli (36.5%(31/85) vs 44.8%(56/125)) and S. agalactiae (24.7%(21/85) vs 28.8%(36/125)) between early onset and late onset cases (both P>0.05). The most common pathogen was E. coli in different regions, with 46.7%(64/137) in Zhejiang Province and 31.5%(23/73) in other regions outside Zhejiang Province. In Zhejiang Province, S. agalactiae was detected in 49 out of 137 cases (35.8%), which was significantly higher than other regions outside Zhejiang Province (11.0%(8/73)). The proportions of Klebsiella pneumoniae, and coagulase-negative Staphylococcus in other regions outside Zhejiang Province (17.8%(13/73) and 16.4%(12/73)) were both higher than those in Zhejiang Province (2.9%(4/137) and 5.1%(7/137)). The differences were all statistically significant ( χ2=14.82, 12.26 and 7.43, respectively, all P<0.05). The proportion of Gram-positive bacteria in Wenzhou City (60.8%(31/51)) was higher than that in other regions in Zhejiang Province (38.4%(33/86)), and the difference was statistically significant ( χ2=6.46, P=0.011). E. coli was sensitive to meropenem (0/45), and 74.4%(32/43) of them were resistant to ampicillin. E. coli had different degrees of resistance to other common cephalosporins, among which, cefotaxime had the highest resistance rate of 41.8%(23/55), followed by ceftriaxone (32.4%(23/71)). S. agalactiae was sensitive to penicillin, vancomycin and linezolid. Conclusions:The composition ratios of pathogenic bacteria of neonatal purulent meningitis are different in different regions of China. The most common pathogen is E. coli, which is sensitive to meropenem, while it has different degrees of resistance to other common cephalosporins, especially to cefotaxime.

Objective:To explore the application effect of empowering psychological nursing intervention on young patients with breast cancer and their spouses.Methods:Using the convenient sampling method, a total of 240 breast cancer patients and their spouses in the First Affiliated Hospital of Zhengzhou University from January 2018 to December 2020 were selected as the research objects. According to the random number table method, they were divided into the observation group and the control group, with 120 cases in each group. The observation group was given empowering psychological nursing intervention, while the control group was given routine psychological nursing intervention. The psychological stress response and negative emotion of the patients and their spouses in two groups before and after intervention were compared.Results:Before intervention, there were no statistically significant differences in scores of Resilience Scale for Adults (RSA) , Symptom Check List 90 (SCL-90) , Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) of patients and their spouses between the two groups ( P>0.05) . After the intervention, the RSA scores of patients and their spouses in the observation group were higher than those in the control group, and the scores of SCL-90, BAI and BDI were lower than those in the control group, and the differences were all statistically significant ( P<0.05) . Conclusions:Empowering psychological nursing intervention can effectively relieve psychological stress reaction and alleviate negative emotions of young patients with breast cancer and their spouses.

Objective:To assess the efficacy and safety of 100 units of botulinum toxin A (BTX-A) intradetrusor injection in patients with overactive bladder.Methods:From April 2016 to December 2018, 17 tertiary hospitals were selected to participate in this prospective, multicenter, randomized, double-blind, placebo-controlled study. Two phases of study were conducted: the primary phase and the extended phase. This study enrolled patients aged 18 to 75 years who had been inadequately managed by anticholinergic therapy (insufficient efficacy or intolerable side effects) and had spontaneous voiding with overactive bladder. Exclusion criteria included patients with severe cardiac, renal and hepatic disorders, patients with previous botulinum toxin treatment for 6 months or allergic to BTX-A, patients with urinary tract infections, patients with urinary stones, urinary tract tumors, diabetes mellitus, and bleeding tendency. Eligible patients were randomly assigned to BTX-A group and placebo control group in a ratio of 2∶1. Two groups of patients received 20 intradetrusor injections of BTX-A 100U or placebo at the depth of the submucosal muscle layer respectively under cystoscope, including 5 injections at the base of the bladder, 3 injections to the bladder triangle, 5 injections each to the left and right walls and 2 injections to the top, sparing the bladder neck. As a placebo control group, patients received same volume of placebo containing no BTX-A and only adjuvant freeze-dried preparations for injection with the same method. A combination of gelatin, sucrose, and dextran served as adjuvants. Average micturition times per 24 hours, urinary incontinence (UI) episodes per day, average micturition volume per day, OAB symptom score(OABSS), and quality of life (QOL) score were recorded at baseline and the 2nd, 6th and 12th week after treatment. The primary efficacy endpoint was the change from baseline in the average micturition times per 24 hours at the 6th week after treatment. The secondary efficacy endpoints included the change from baseline in the average micturition times per 24 hours at 2nd and 12th week, as well as the change from baseline in the OABSS, QOL score, average frequency of urgency and UI episodes per day, urgency score, average micturition volume per day at 2nd, 6th and 12th week after treatment. Patients were followed for 12 weeks to assess adverse events (AEs). After assessed at week 12, if the micturition times has decreased less than 50% compared to baseline and the patient is willing to receive retreatment, then patients could enter the extended trial phase. In that phase, patients in both groups were injected with 100 units BTX-A from 12th week onwards and then followed up the same indicators for 12 weeks.Results:216 patients were enrolled in this trial (144 cases in the BTX-A group and 72 cases in the placebo control group). Baseline characteristics such as age (47.75±14.20 in the BTX-A group and 46.39±15.55 in the control group), sex (25 male/117 female in the BTX-A group and 10/61 in the control group), and disease duration (0.51 years in the BTX-A group and 0.60 years in the control group) were balanced between the two groups( P>0.05). A marked reduction from baseline in average micturition times per 24 hours was observed in all treatment groups at the 6th week and the reduction of the two groups was statistically different ( P<0.001 and P=0.008 respectively). Compared with the baseline, the average micturition times per 24 hours at the 6th week decreased from baseline by 2.40(0.70, 4.60)times for the BTX-A group and 0.70(-1.00, 3.30) times for the placebo control group respectively, and the difference between the two groups was considered to be statistically significant ( P=0.003). The change rates of average micturition times per 24 hours from baseline at the 6th week of the two groups were (16±22)% and (8±25)% respectively, and the difference between the two groups was statistically significant ( P=0.014). Compared with the baseline, the average micturition times per 24 hours at 2nd and 12th week decreased by 2.00(0.00, 4.00)and 3.30(0.60, 5.03)for the BTX-A group, 1.00(-1.00, 3.00)and 1.70(-1.45, 3.85)for the placebo control group respectively. The difference between two groups was considered to be statistically significant ( P=0.038 and P=0.012); the changes of average urgency times per day for the BTX-A group and the control group at the 2nd, 6th and 12th week were 2.00(0.00, 4.30)and 2.40(0.30, 5.00), 3.00(0.30, 5.70)and 0.70(-1.30, 2.70), 0.70(-1.30, 3.00) and 1.35(-1.15, 3.50), respectively. There were significant differences between two groups at the 2nd, 6th and 12th week, ( P=0.010, P=0.003 and P=0.025, respectively). The OABSS of the BTX-A group and the control group at the 6th week decreased by 1.00(0.00, 4.00)and 0.50(-1.00, 2.00) compared with the baseline, and the difference between the two groups was statistically significant ( P=0.003). 47 cases of BTX-A group and 34 cases of placebo control group entered the extended trial phase, and 40 and 28 cases completed the extended trial phase, respectively. The average micturition volume per 24 hours changed by -16.60(-41.60, -0.60)ml and -6.40(-22.40, 13.30)ml, (-35.67±54.41)ml and(-1.76±48.69)ml, (-36.14±41.51)ml and (-9.28±44.59)ml, (-35.85±43.35)ml and(-10.41±40.29)ml for two groups at the 12th, 14th, 18th and 24th week, and the difference between two groups was statistically significant at each follow-up time ( P=0.01, 0.006, 0.012 and 0.016, respectively). There was no significant difference in other parameters( P>0.05). However, adverse reactions after intradetrusor injection included increased residual urine volume (27 in the BTX-A group and 3 in the control group), dysuria (21 in the BTX-A group and 6 in the control group), urinary infection (19 in the BTX-A group and 6 in the control group), bladder neck obstruction (3 in the BTX-A group and 0 in the control group), hematuria (3 in the BTX-A group and 1 in the control group), elevated alanine aminotransferase (3 in the BTX-A group and 0 in the control group), etc. During the follow-up period, there was no significant difference in the other adverse events between two groups except the increase of residual urine volume( P<0.05). In the primary trial phase, among the 27 cases with increased residual urine volume in BTA group, only 1 case (3.70%) with PVR more than 300 ml; the PVR of 3 patients in the placebo group was less than 100 ml. The increase of residual urine volume caused by the injection could be improved or disappeared with the passage of time. Conclusions:Intradetrusor injection of Chinese BTX-A improved the average micturition times per 24 hours, the average daily urgent micturition times, OABSS, and average micturition volume per time, and reduced the adverse effects in patients with overactive bladder.Chinese BTX-A at dose of 100U demonstrated durable efficacy and safety in the management of overactive bladder.

Objective:To evaluate the effects of ultrasound-guided quadratus lumborum block (QLB) on acute pain after total hip arthroplasty.Methods:A retrospective study was conducted of the 36 patients with hip osteoarthritis who had undergone selective one-side total hip arthroplasty under total intravenous anesthesia (TIVA) from January 2019 to January 2020. According to whether additional QLB was used or not they were divided into 2 equal groups ( n=18). The control group of 10 males and 8 females with an age of 60.5±9.4 years used mere TIVA while the QLB group of 7 males and 11 females with an age of 53.6±12.7 years used TIVA plus QLB. All patients accepted patient-controlled intravenous analgesia (PCIA) postoperatively. The 2 groups were compared in terms of visual analogue scale (VAS) at rest and during exercise and IL-6 level at 24 h postoperation, consumption of opioids and postoperative incidence of nausea and vomiting. Results:There were no significant differences between the 2 groups in their preoperative general data, indicating they were compatible ( P>0.05). The VAS scores at rest and during exercise in the QLB group (0.3 ± 0.5 and 0.8 ± 0.6) were significantly lower than in the control group (2.1 ± 0.7 and 2.7 ± 0.5), the IL-6 level in the former[40.9 (30.5, 56.3) pg/mL] was significantly lower than in the latter[165.0 (82.5, 276.5) pg/mL], the intraoperative total consumptions of sufentanil[6 (6, 7) μg] and remifentanil[1,370 (1,200, 1,485) μg] in the former were significantly lower than in the latter[35 (30, 40) μg and 1, 910 (1, 805, 2, 000) μg], and the postoperative incidenceof nausea and vomiting[27.8%(5/18)] in the former was significantly lower than in the latter[77.8%(14/18)] (all P<0.05). Conclusions:Ultrasound-guided quadratus lumborum block can effectively relieve acute pain in patients after total hip arthroplasty. It can suppress stress-related inflammatory factors, reduce consumption of opioids and incidence of postoperative nausea and vomiting.

Objective: To investigate the effect of hepatitis B virus (HBV) X gene integration on expression of zinc finger protein ZBTB20 in chronic hepatitis B (CHB) patients complicated with hepatocellular carcinoma (HCC). Methods: Eighteen CHB patients complicated with HCC who underwent surgical treatment in Taizhou Enze Medical Center Enze Hospital and Taizhou Central Hospital from July 2015 to June 2017 were enrolled. Samples of carcinoma tissue, para-carcinoma tissue and corresponding normal liver tissue were collected from each case. DNA was extracted from three kinds of tissue samples. HBV-Alu-polymerase chain reaction (PCR) was used to amplify the integrated HBVX fragments and their bilateral flanking sequences in human genomic DNA. The integrated HBV fragments were determined by PCR products sequencing. Protein was extracted from three kinds of tissue samples.The level of expression of ZBTB20 was detected by protein imprinting. Statistical analysis was performed using t test, analysis of variance, and χ² test. Results: Among the 18 CHB patients complicated with HCC, integration of HBVX gene was found in 13 carcinoma tissue samples, 16 para-carcinoma tissue samples and 9 corresponding normal liver tissue samples. The difference was statistically significant (χ²=6.353, P=0.037). Of the 18 patients, the protein expressions of ZBTB20 in carcinoma tissue, para-carcinoma tissue and corresponding normal tissue were (50.14±11.25)%, (40.71±7.17)% and (39.06±5.17)%, respectively, which was statistically different (F=9.420, P<0.01). HBVX gene integration was detected at ZBTB20 locus in five patients. The expression levels of ZBTB20 in patients with HBVX gene integration at this locus in carcinoma tissue, para-carcinoma tissue and corresponding, normal liver tissue were all significantly lower than those in patients without HBVX gene integration (carcinoma tissue (37.37±10.30)% vs (55.06±7.06)%, para-carcinoma tissue (32.06±2.61)% vs (44.04±5.24)%, corresponding normal tissue (34.66±5.59)% vs (40.76±4.04)%, t=4.205, 4.821 and 2.589, respectively, all P<0.05). Conclusions Incidence of HBVX integration in para-carcinoma tissue is higher than that in carcinoma tissue in CHB patients complicated with HCC.The expression level of ZBTB20 in carcinoma tissue is higher than that in para-carcinoma tissue. Integration of HBVX gene at ZBTB20 locus may decreases the expression of ZBTB20.

Objective To evaluate the feasibility of developing hospital acquired pneumonia (HAP) risk warning model in critically ill patients based on genomic copy number polymorphisms (CNPs) of the genes encoding human neutrophil peptides 1-3 (DEFA1/DEFA3).Methods Seventy-seven HAP patients (group HAP) and 109 non-HAP patients of matched age and sex in intensive care unit (ICU) (group NHAP) were enrolled in the study.The genomic CNPs of DEFA1/DEFA3 was determined by realtime quantitative polymerase chain reaction after extracting DNA from peripheral blood samples.The source of patients,condition of endotracheal intubation within 24 h after admission to ICU,Acute Physiology Score,Acute Physiology and Chronic Health Evaluation Ⅱ score,Sequential Organ Failure Assessment score,mechanical ventilation time,length of hospital and ICU stay and outcomes were obtained.The predictive model was developed using logistic regression through combining DEFA1/DEFA3 copy numbers and clinical characteristics (Acute Physiology Score and source of emergency) within 24 h after admission to ICU.The receiver operating characteristic curve was used to evaluate the predictive efficacy of the model.Results The copy numbers of DEFA1/DEFA3 were significantly lower in HAP group than in NHAP group (P ＜0.05).The area under the receiver operating characteristic curve of the predictive model developed through combining the DEFA1/DEFA3 copy numbers with clinical characteristics was 0.789 (95％ CI 0.724-0.854) when the model was used for predicting HAP.Conclusion CNPs of DEFA1/DEFA3 can be used to develop the HAP risk warning model in critically ill patients.

Objective To investigate the effect of ultrasound-guided stellate ganglion block ( SGB) on perioperative inflammatory responses and postoperative recovery of gastrointestinal function in patients un-dergoing gastrointestinal surgery. Methods Fifty-five American Society of Anesthesiologists physical classⅠ-Ⅲpatients of both sexes, aged 18-64 yr, weighing 50-75 kg, undergoing elective gastrointestinal sur-gery, were divided into SGB group ( n=18) and control group ( C group, n=37) using a random number table method. Ultrasound-guided SGB was conducted with 0. 5％ ropivocaine 7 ml at the left C6 level in SGB group. The equal volume of normal saline was given under ultrasound guidance at the same site in C group. Peripheral venous blood samples were collected at 5 min before SGB and 2, 4 and 24 h after SGB for deter-mination of plasma tumor necrosis factor-α ( TNF-α) , interleukin ( IL)-1β and IL-6 concentrations by en-zyme-linked immunosorbent assay. The increased level of leukocyte count ( leukocyte count at 24 h after SGB-leukocyte count at 24 h before SGB) was recorded. The recovery time of bowel sounds and anal or sto-ma exhaust time were also recorded. Results Compared with C group, the concentrations of TNF-αat 2 h after SGB and IL-1βat 2, 4 and 24 h after SGB were significantly decreased, the increased level of leuko-cyte count was decreased, and the recovery time of bowel sounds and anal or stoma exhaust time were short-ened in SGB group ( P<0. 05) . Conclusion Ultrasound-guided SGB can reduce perioperative inflammato-ry responses and promote the recovery of postoperative gastrointestinal function in the patients undergoing gastrointestinal surgery.

Objective To explore the protective effect of resveratrol (RSV) on intestine barrier injury induced by hemorrhagic shock and its mechanism in rats.Methods According to random number table method,sixty-four SPF grade male Sprague-Dawley (SD) rats were divided into four groups:Sham operation group (only the catheters were indwelled in arterial and venous passages after anesthesia),hemorrhagic shock model group (model group,the catheters were indwelled in arterial and venous passages after anesthesia,and 0.3 mL solvent was administrated after hemorrhagic shock),RSV group (the catheters were indwelled in arterial and venous passages after anesthesia,15 mg/kg RSV was administered after hemorrhagic shock),superoxide dismutase 2 (SOD2) specific inhibitor,2-Methoxyoestradiol (2-ME) group (on the basic treatment of RSV group,0.1 mmol/L 2-ME was administered).The hemorrhagic shock model was reproduced by femoral artery bleeding.After drug administration,all rats were divided into two parts.One part was used for observations on 24-hour survival rate and survival time,while in the other part,2 hours after the hemorrhagic shock,the blood was collected for determination of the content of serum D-lactic acid,and afterward the rats were executed to obtain small intestine tissues for the examination of histopathological changes and Chiu's score.Moreover,differences of expression levels of tight junction proteins (Occludin,Claudin,ZO-1) of small intestine tissue and the oxidative stress related indexes SOD2 activity and reduced glutathione (GSH),oxidized glutathione (GSSH),malonaldehyde (MDA) contents were compared among the groups.Results Compared with the sham group,the model group demonstrated decreased survival rate,SOD2 activity,GSH content,GSH/GSSH ratio,reduced survival time,significantly increased serum D-lactic acid activity,Chiu's score and MDA content,and decreased expressions of tight junction proteins in small intestine tissue.Compared with model group,the RSV group showed significant increased survival rate [75.0％ (6/8) vs.37.5％ (3/8)] and prolonged survival time (hours:21.0±4.3 vs.10.4±5.8,P ＜ 0.05),significantly decreased serum D-lactic acid (μg/L:380.18 ± 70.59 vs.500.88 ± 97.53) and Chiu's score (1.75 ± 0.71 vs.4.00± 0.53) in small intestine (both P ＜ 0.05),obviously increased expressions of tight junction proteins,SOD2 activity,GSH and GSH/GSSG [Occludin (gray value):0.89 ± 0.10 vs.0.43 ± 0.77,Claudin (gray value):0.78±0.06 vs.0.33 ± 0.05,ZO-1 (gray value):0.83 ± 0.06 vs.0.34 ± 0.07,all P ＜ 0.05],and the elevated SOD2 activity (kU/L:0.85 ± 0.12 vs.0.51 ± 0.11,P ＜ 0.05],as well as increased GSH content and GSH/GSSG ratio [GSH (μmol/L):7.25±1.01 vs.3.86±0.54,GSH/GSSG:6.39± 1.14 vs.1.56±0.25,both P ＜ 0.05] in the small intestine,and markedly reduced MDA content (ng/g:5.00± 1.31 vs.8.63±0.92,P ＜ 0.05).Compared with RSV group,the 2-ME group demonstrated significantly decreased survival rate [50.0％ (4/8) vs.75.0％ (6/8)] and further shorter survival time (hours:12.2 ± 5.7 vs.21.0±4.3),increased serum D-lactic acid (μg/L:463.88 ± 60.16 vs.380.18 ± 70.59),obviously elevated Chiu's score (3.13 ± 0.99 vs.1.75±0.71,P ＜ 0.05),decreased expressions of tight junction proteins [Occludin (gray value):0.55±0.04 vs.0.89±0.10,Claudin (gray value):0.38±0.05 vs.0.78±0.06,ZO-1 (gray value):0.41±0.04 vs.0.83±0.06,all P ＜ 0.05];moreover,the activity of SOD2,GSH content,GSH/GSSG ratio were greatly reduced [SOD2 activity (kU/L):0.58 ± 0.13 vs.0.85 ± 0.12,GSH (μmol/L):4.49 ± 0.52 vs.7.25 ± 1.01,GSH/GSSG:1.57 ± 0.39 vs.6.39 ± 1.14,all P ＜ 0.05],and increased MDA content (ng/g:6.25 ± 1.04 vs.5.00 ± 1.31,P ＜ 0.05).The small intestine tissue was basically normal in Sham group,and no significant pathological changes were seen;in the model group,the small intestine epithelial mierovilli were collapsed and the mucosal barrier was destroyed obviously;in the RSV group the damages of small intestine microvilli and barrier were markedly alleviated;in 2-ME group the pathological changes were more evident compared with those in the RSV group.Conclusion RSV can improve intestinal barrier injury following hemorrhagic shock in rats;its mechanism may be related to SOD2 activation.
