Objective To summarize the nursing methods for patients with chronic congestive heart failure treated with local renal nerve block. Methods 10 cases of patients with chronic congestive heart failure were treated with renal nerve block. The blood and urine electrolytes, plasma neuroendocrine hor-mones, the 24-hour urine volume were measured before and after the renal nerve block to calculate the rate of excretion of urinary sodium. The changes of the heart rate and blood pressure and the improvement of the dyspnoea, swelling and other symptoms of heart failure were monitored continuously before and after the re-nal nerve block. Results There was a significant increase in the 24-hour urine volume and the rate of excretion of urinary sodium in the patients with heart failure after the renal nerve block (P<0.05),and there was a significant decrease in the amount of plasma neuroendocrine hormones after the renal nerve block (P<0.01);there was no signifieant changes in the heart rate and the average blood pressure with improvement of dyspnoea, swelling and other symptoms of heart failure. No significant complications were found. Conclusions The nursing measures taken by the nurses in the clinical application of local renal nerve block as a new treatment modality to the treatment of patients with chronic congestive heart failure are safe, effective and feasible.

Objective:To investigate the expression of circhipk3 in microglial cells in heat-induced neurological injury, and to preliminary analyze the effect of circhipk3 on microglial polarization in heat-induced neurological injury.Methods:Mice were randomly (random number) divided into a control group and a heat radiation disease 0.8 h group (HS 0.8), a heat radiation disease 8h group (HS 8), and a heat radiation disease 24 h group (HS 24). By establishing a mouse model of heat shock (HS), heat-damaged brain tissue was obtained, microglia were isolated and RNA was extracted. Quantitative PCR method was used to detect M1 and M2 marker molecules in microglia, and to evaluate the polarization direction and type of microglia. The expression level of circhipk3 was detected in microglial cells in heat-induced neurological injury, and the effect of circhipk3 on microglial polarization was further elucidated by intervening the expression of circhipk3 in microglial cells.Results:The expression of CD45 and CD11-b in the HS 8 group was significantly higher than that in the control group [(4.41±0.18) vs. (1±0.15), P=0.000], [(3.47±0.19) vs (1±0.15), P=0.000] , and the CD45 and CD11-b of the HS 24 group was significantly lower than that of the HS 8 group [(1.34±0.15) vs. (4.41±0.18), P=0.000], [(1.38±0.21) vs. (3.47±0.19), P= 0.001]. At the same time, the expression of CD206, FIZZ and Arg1 in the HS 8 group started to increase compared with the control group [(1.59±0.16) vs. (1±0.12), P=0.014], [(1.62±0.15) vs. (1±0.15), P=0.002 ], [(2.23±0.28) vs. (1±0.19), P=0.004], and CD206, FIZZ, and Arg1 in the HS 24 group were significantly higher than those in the control group [(2.67±0.20) vs. (1±0.12), P=0.002], [(2.19±0.15) vs. (1±0.15), P=0.000], [(3.04±0.18) vs. (1±0.19), P=0.001]; circhipk3 mimicis significantly increased the expression of Arg1 [(7.26± 0.06) vs. (3.86±0.06), P=0.000]; at the same time, circhipk3 inhibitor promoted the expression of CD45 and HO-1 [(2.96±0.03) vs. (1.63±0.09), P=0.000], [(2.52±0.10) vs. ( 1.30±0.02), P=0.000]. Conclusions:Microglial cells are predominantly M1-type in early neurological injury of heat radiation disease. HO-1 may be one of the microglial M1-type markers. The high expression of circhipk3 in microglial cells mainly promotes its transformation to M2 type.

OBJECTIVETo discuss indications and therapeutic effects of concomitant surgery for stress urinary incontinence (SUI) and pelvic organ prolapse (POP) through a retrospective clinical review.

METHODA retrospective review of the data of 16 women undergoing concomitant surgery for SUI and POP was available for analysis. In these cases, 12 patients presented with SUI symptoms associated with moderate or severe anterior vaginal wall prolapse; 4 patients had moderate or severe uterine prolapse associated with dysuria. All cases were confirmed to have type II stress urinary incontinence by preoperative physical examination, urodynamic study and cystography. The surgical procedures for pelvic floor repair included the placement of Gynemesh mesh implant, anterior or total Prolift mesh implant. The tension-free vaginal tape (TVT) or transvaginal tension free vaginal tape-obturator (TVT-O) was used for the anti-incontinence procedure. During the concurrent surgical procedures, pelvic floor repair was performed first.

RESULTSFollowed up from 6 to 30 months, all cases got satisfactory results. After the procedure, the patients achieved complete continence without occurrence of dysuria or recurrence of POP.

CONCLUSIONSStress incontinence and pelvic organ prolapse share common pathophysiologic etiologies and often coexist with one another. In SUI patients with symptomatic or moderate to severe POP, concurrent POP surgery should be performed actively at the time of incontinence surgery to prevent POP exacerbation and the occurrence of dysuria; while in patients with sole POP, occult SUI should be considered, and concomitant prophylactic incontinence measures should be taken at the time of POP repair to prevent the postoperative unmasking of SUI.

Objective To evaluate the capability and accuracy of multi-shce spiral computed tomography(MSCT)in detecting atherosclerotic plaques in nonstenotic coronary arteries with reference to the findings of intravascular ultrasound(IVUS)in a segment analysis.Methods Both IVUS exams and 16-row MSCT scans were performed on 35 consecutive patients among whom 30 patients had successful MSCT scans.A total of 94 coronary segments without significant coronary stenoses were paired-analyzed both on IVUS and MSCT segment by segment.The plaques were classified as calcified,fibrotic and soft types according to the echogeneity on IVUS.Plaque attenuation on MSCT was measured and expressed by Hounsfield units(HU).Results When referred to IVUS,MSCT had a sensitivity of 82.1%(46/56)and specificity of 89.5% (34/38),respectively in detectiong any plaques.For the detection of calcified plaques,the sensitivity and specificity were 92.1%(35/38)and 96.4%(54/56),respectively.For the detection of mixed and noncalcified plaques,MSCT had sensitivity of 73.2%(30/41)and specificity of 88.7%(47/53).But for the detection of the noncalcified plaque,the sensitivity was 66.7%(12/18). According to the findings On IVUS,the plaques were classified as calcified(n=19),fibrotic(n=19)and soft(n=16).The CT attenuation of calcified plaques was(489?169)HU(196 to 817 HU),fibrotic plaques(69?21)HU(25 to 117 HU)and soft plaques(23?18)HU(-12 to 47 HU).Nonparametric Kruskal-Wallis test revealed a significant difference of plaque attenuation among the three groups(P

Objective To analyze the effect on clinical outcome of sepsis patients treated by early positive and standardized treatment in primary hospitals. Methods The clinical data of sepsis patients admitted to intensive care unit (ICU) of Dushanzi People's Hospital from January 1, 2015 to December 31, 2018 were retrospectively analyzed. The sepsis patients were further divided into a control group (from January to December, 2015) who received non-standardized treatment of sepsis, only according to doctors' experience, using routine antibiotics, fluid resuscitation, detection of lactic acid, etc. and a study group; from 2016, the patients with sepsis (the study group) received standardized diagnosis and treatment according to the Guidelines of Sepsis 3.0 and the actual conditions of our hospitals, and they were further subdivided into three periods: 2016 (from January to December, 2016), 2017 (from January to December, 2017), and 2018 (from January to December, 2018) periods. The main clinical outcome indicator of these patients in 4 time periods, 28-day mortality, the secondary clinical outcome indicators such as the length of stay in ICU and medical expenses in ICU were observed. Results Sixty-six patients with sepsis were finally enrolled, including 17 cases in 2015, 18 cases in 2016, 17 cases in 2017 and 14 cases in 2018. Compared with 2015, the length of ICU stay in 2016, 2017 and 2018 were significantly shorter (days: 17.45±9.09, 12.95±5.93, 12.14±4.92 vs. 20.85±13.45, all P <0.05), and the medical cost of ICU stay were significantly lower (ten thousand yuan: 9.93±5.35, 7.22±3.86, 5.15±2.88 vs. 13.37±14.14, all P < 0.05); the 28-day mortality was significantly decreased [16.67% (3/18), 11.76% (2/17), and 14.29% (2/14) vs. 35.3% (6/17), all P < 0.05]. Conclusion Early standardized treatment for patients with sepsis can significantly reduce the length of stay in ICU and medical expenses in ICU.

OBJECTIVEA CAT reporter plasmid (pBLCAT3alpha1) driven by the promoter of hsp90alpha was in vitro assembled into chromatin to investigate the transcription activity of the reporter gene upon heat shock.

METHODSA competitive RT-PCR-based technique was used to quantify the promoter activity of hsp90alpha gene on chromatin or naked DNA templates in vitro.

RESULTSThe in vitro transcription efficiency was first optimized by using different amounts of whole cell extracts from heat shock-treated HeLa cells. In vitro chromatin assembly was carried out with purified components of chromatin assembly associated factors, core histones and CAT reporter gene driven by the promoter of hsp90alpha gene. Results showed that chromatin formation repressed the in vitro transcription of the gene.

CONCLUSIONThe heat shock induced transcription of hsp90alpha gene on chromatin template is more efficient than that on naked DNA in vitro.

OBJECTIVETo explore the diagnostic value of ThinPrep cytology test (TCT) in lung cancer.

METHODS353 cases of bronchoalveolar lavage fluid (BALF) and(or) bronchial brushing cytology (192 cases from lung cancer patients and 161 cases from benign lung disease patients) were detected with TCT and method of direct smear, respectively. The sensitivity and specificity of two methods was compared.

RESULTSThe sensitivity and specificity of TCT were 39.6% and 99.4%. And which of direct smear method were 8.3% and 100%, respectively. The sensitivity of TCT was significantly higher than that of method of direct smear in the diagnosis of lung cancer (P < 0.01). There were 71 patients who underwent BALF and bronchial brushing cytology simultaneously, the sensitivity of TCT of BALF was higher than that of bronchial brushing cytology (P < 0.05). Of the 69 cases which had both TCT and histopathological results, TCT and pathology concordance rate was 84.1%.

CONCLUSIONTCT has more diagnostic value in lung cancer; BALF is more preponderant than bronchial brushing cytology by TCT in the diagnosis of lung cancer.

BACKGROUNDDespite 100 years of research, the continued absence of well-established risk factors impedes the diagnosis and treatment of interstitial cystitis/painful bladder syndrome (IC/PBS). We aimed to identify risk factors in patients with lower urinary tract symptoms (LUTS) without urinary tract infection or benign prostate hyperplasia in China.

METHODSA total of 397 outpatients with LUTS presenting for care to urology clinics in several hospitals throughout China were surveyed using a standardized questionnaire and validated outcome measures. The definitions for painful bladder syndrome based on the O'Leary-Sant interstitial cystitis symptom and problem indices were used. The prevalence of possible risk factors was analyzed using the Fisher's exact test and Pearson chi-square test, and multivariate predictive models were developed using binary Logistic regression methods.

RESULTSOf those multi-centre patients surveyed, including 174 women and 223 men, 41% (162/397) met criteria for painful bladder syndrome. There was a significant difference between women and men (55% (95/174) vs. 30% (67/223), P < 0.001). Women with IC/PBS were more likely than those without IC/PBS to report a history of gynecological infections (odds ratio (OR): 2.85; 95% confidence interval (CI): 1.32 - 6.16, P = 0.007), intake of stimulatory foods (OR: 3.52; 95%CI: 1.50 - 8.30; P = 0.004), irritable bowel (OR: 3.46; 95%CI: 1.22 - 9.80; P = 0.014) and/or anorectal disease (OR: 2.68; 95%CI: 1.12 - 6.40, P = 0.023). After adjusting for confounding factors, bladder pain was significantly associated with stimulatory foods (OR: 3.85; 95%CI: 1.58 - 9.36, P = 0.003) and anorectal disease (OR: 2.76; 95%CI: 1.09 - 7.04, P = 0.03) in women. Caffeine beverage intake (OR: 3.54; 95%CI: 1.54 - 8.12, P = 0.003) was identified the only modifiable association noted in multivariate analysis of men.

CONCLUSIONSWe found that stimulatory foods, anorectal disease and caffeine beverages are potential risk factors for IC/PBS. Further studies are necessary to determine their role in the pathogenesis of this disorder.

BACKGROUNDReports on mood regulating circuit (MRC) indicated different activities between depressed patients and healthy controls. The functional networks based on MRC have not been described in major depression disorder (MDD). Both the anterior cingulate cortex (ACC) and thalamus are all the key regions of MRC. This study was to investigate the two functional networks related to ACC and thalamus in MDD.

METHODSSixteen patients with MDD on first episode which never got any medication and sixteen matched health controls were scanned by 3.0 T functional magnetic resonance imaging (fMRI) during resting-state. The pregenual anterior cingulate cortex (pgACC) was used as seed region to construct the functional network by cortex section. The thalamus was used as seed region to construct the functional network by limbic section. Paired-t tests between-groups were performed for the seed-target correlations based on the individual fisher z-transformed correlation maps by SPM2.

RESULTSDepressed subjects exhibited significantly great functional connectivity (FC) between pgACC and the parahippocampus gyrus in one cluster (size 923) including left parahippocampus gyrus (-21, -49, 7), left parietal lobe (-3, -46, 52) and left frontal lobe (-27, -46, 28). The one cluster (size 962) of increased FC on thalamus network overlapped the precuneus near to right parietal lobe (9, -52, 46) and right cingulate gyrus (15, -43, 43) in health controls.

CONCLUSIONSAbnormal functional networks exist in earlier manifestation of MDD related to MRC by both cortex and limbic sections. The increased functional connectivity of pgACC and decreased functional connectivity of thalamus is mainly involved in bias mood processing and cognition.
