Objective To assess the effect of neutrophil?to?lymphocyte ratio ( NLR) on the recurrence rate of patients with alpha?fetoprotein (AFP) ?negative hepatocellular carcinoma (HCC) and the value of NLR in predicting prognosis. Methods The clinical data of seventy?seven patients diagnosed with AFP?negative HCC and treated with hepatocellular carcinoma surgery in the First Hospital in Weinan from June 2015 to March 2017 were analyzed. According to the recurrence at the end of the follow?up, the patients were divided into the recurrence group and the non?recurrence group. Cox single factor analysis was used to analyze the relationship between the clinicopathological features and postoperative recurrence, and the clinical risk factors with statistically significance in the univariate analysis were placed in the Cox multivariate regression analysis to determine whether it is independent risk factor. Results The differences between the two groups in the number of tumors (31/15,28/3),tumor size (>5 cm) (5. 53±1. 83,4. 65±1. 73),portal vein tumor thrombus (18/28,2/29),microvascular invasion (14/32,2/29) were all statistically significant (P<0. 05). Cox univariate analysis showed that preoperative NLR levels ( RR=1. 125, 95%CI 1. 052-1. 203, P=0. 029 ) , tumor number ( RR=0. 943,95%CI 1. 007-1. 330, P=0. 019 ) , tumor size (>5 cm ) ( RR=0. 550, 95%CI 0. 316-0. 956, P=0. 038),portal vein tumor thrombus (RR=1. 294,95%CI 1. 208-1. 386,P=0. 022),microvascular invasion (RR=1. 575,95%CI1. 209-2. 052,P=0. 028) were the risk factors of postoperative recurrence. Cox regression model showed that tumor number (RR=1. 830,95%CI 1. 184-2. 828,P=0. 026),portal vein tumor thrombus ( RR=2. 860,95%CI 2. 062-3. 968,P=0. 001) ,microvascular invasion ( RR=1. 760,95%CI 1. 019-3. 041,P=0. 037) and preoperative NLR level ( RR=1. 890,95%CI 1. 056-3. 383,P=0. 028) were independent risk factors of the recurrence in AFP negative HCC patients after surgery. Among the 77 patients,46 cases were in the recurrent group, the average value of NLR was 3. 49 ± 0. 30, and the average preoperative NLR of the non?recurrence group ( 31 patients ) were 3. 01 ± 0. 30, the difference between the two groups in NLR value was statistically significant (t=-6. 885,P=0. 000). According to the ROC curve,the NLR=3. 17 corresponded to the maximum Youden index,the sensitivity of NLR was 82. 6%,the specificity was 67. 7%. Conclusion The preoperative NLR level is inversely proportional to the recurrence?free survival time of patients with AFP?negative HCC,which is one of the independent risk factors for recurrence. The optimal critical value of NLR is 3. 17.

Objective:To evaluate the effectiveness of strengthening management in the bronchial asthma control among community patients.Methods:One hundred and eighteen community patients with bronchial asthma were recruited from January 2017 to January 2018. The patients were divided into community strengthening management group ( n=60) and control group ( n=58), the annual times of acute attack, time to first exacerbation and annual medical expenses were compared between the two groups. The proportion of inhaled corticosteroid (ICS) administration was documented; the Asthma Control Test (ACT), the Mini Asthma Quality of Life Questionnaire (MiniAQLQ), Leicester Cough Questionnaire (LCQ), Fractional exhaled nitric oxide(FeNO) and pulmonary function were evaluated in two groups. Results:The management group had greater improvements in the proportion of ICS administration [45(75.0%) vs.36(62.1%), χ 2=4.143], ACT [(20.7±3.9) vs.(18.1±4.1), t=3.213], LCQ [(13.5±5.3) vs.(10.8±3.0), t=2.603], FeNO [(29.8±12.8) vs. (37.1±11.1), t=2.018] than the control group after six months of management (all P<0.05). There were significantly greater improvements in proportion of ICS treating [50(83.3%) vs. 34(58.6%), χ 2=5.748], ACT [(22.1±2.8) vs. (19.5±2.3), t=2.241], LCQ [(16.5±4.2) vs. (11.6±3.2),=5.603], miniAQLQ [(83.2±11.1) vs.(68.1±13.3), t=3.186] and FeNO [(28.2±13.1) vs.(38.1±16.3), t=2.176] in management group than those in control group after one year of management (all P<0.05); but no differences were seen in FEV 1%, FVC%, FEV 1/FVC (all P>0.05) between two groups. The LCQ score [(16.5±4.2) vs. (13.5±5.3), t=3.186] and the MiniAQLQ score [(83.2±11.1) vs. (69.1±14.3), t=5.603] of the management group were significantly improved after 1 year of management than those after 6 months. There was significant improvement in time to first exacerbation [182(92, 284) vs. 92(58, 176), Z=4.384] and the annual exacerbation was significantly reduced [0(0, 1) vs. 2(1, 3), Z=-3.187], annual medical costs of management group were significantly lower than those of control group [(10 523.0±550.5)Yuan vs. (15 787.1±1 421.2)Yuan, t=2.653]. Conclusion:The strengthening management can effectively improve the control rate of bronchial asthma, reduce acute exacerbation, improve clinical symptoms and improve the quality of life in community patients with bronchial asthma.

Objective: The goal of this research was to understand the demographic distribution and related factors of non-marital and non-commercial heterosexual transmission (non-commercial transmission) for HIV/AIDS (human immunodeficiency virus/acquired immunodeficiency syndrome). Methods: Data related to HIV/AIDS infected by non-marital heterosexual transmission and whose present address was in Qian Dongnan, were collected from Information System on the HIV/AIDS Prevention and Control. Information included demographic characteristics, the members of non-marital sex partners, transmission path, detection source, CD4⁺T lymphocyte level, et al. cases belong to homosexual history, injective drug use or non-classified non-marital heterosexuality transmission were excluded, totally collect HIV/AIDS 919 cases. Multivariate logistic regressions were used to analyze potential factors associated with non-marital and non-commercial heterosexual transmission. In addition, in March and June 2017, using a convenience sampling, we conducted one-to-one interviews among 10 HIV/AIDS who were infected by non-marital heterosexuality and had non-marital and non-commercial heterosexual experience in Kaili Center for Disease Control and Prevention. The content of the interview included basic information, sexual orientation, the main place of making friends and sexual behavior, attitude to commercial heterosexuality and non-martial and non-commercial heterosexuality and so on. Results: Out of the 919 cases, 645 (70.2%) were male, the proportion of non-commercial transmission was 55.06% (506). The proportion of female HIV/AIDS with non-commercial transmission was 84.7% (232), which was higher than male (42.5%(274)) (χ²=138.35, P<0.001). The proportion of Han HIV/AIDS with non-commercial transmission was 61.5% (275), which was higher than other religion (52.2%(412)) (χ²=6.32, P=0.012). The proportion of HIV/AIDS with non-commercial transmission who had 0-5 non-marital sexual partners was 58.8% (498), which was higher than who had>5 non-marital sexual partners (11.1%(8)) (χ²=61.10, P<0.001). The proportion of HIV/AIDS with non-commercial transmission who lived mobile was 72.9% (94), which was higher than who lived fixedly (52.2%(412)) (χ²=19.34, P<0.001). Qualitative interviews results revealed that the age of the respondents were 22-69. Respondents whose ages are in 22-34 were more likely to use mobile phone (4/10) and respondents whose ages are in 35-69 were less likely to look partners through party and the context of working. Conclusion The proportion of cases being infected by non-marital and non-commercial heterosexual transmission in Qian dongnan was higher than general national levels. The characteristics of sex, marriage status, migration, vocation, the members of non-marital sex partners were significant differed between commercial heterosexual transmission and non-marital and non-commercial heterosexual transmission.

In recent years,with in-depth study of bladder sensation related mechanisms,numerous ion channels,neurotransmitters and nerve receptors have been found to participate in the regulation of bladder sensation,including TRPV,P2X and Piezo,as well as CBR and HCN.Thanks to the relevant research on the neural signal pathway from the cerebral cortex to the bladder wall and the maturity of clinical measurement methods for bladder sensation,we can further study the abnormal bladder sensation in patients with overactive bladder(OAB),so as to explore its mechanism.Bladder hypersensitivity,as one of the current research hotspots,is receiving increasing attention from researchers.This article reviews the mechanism of bladder hypersensitivity from the aspects of clinical measurement methods of bladder sensation,ion channel,neurotransmitters and nerve receptors related to bladder sensation,in order to explore its significance in the pathogenesis of OAB.

Objective:To summarize the experience of surgical treatment of primary liver cancer.Methods:The clinical data of 10 966 surgically managed cases with primary liver cancer, from January 1986 to December 2019 at Hepatobiliary Center, the First Affiliated Hospital of Nanjing Medical University, were retrospectively analyzed. The life table method was used to calculate the survival rate and postoperative recurrence rate. Log‐rank test was used to compare the survival process of different groups, and the Cox regression model was used for multivariate analysis. In addition, 2 884 cases of hepatocellular carcinoma(HCC) with more detailed follow‐up data from 2009 to 2019 were selected for survival analysis. Among 2 549 patients treated with hepatectomy, there were 2 107 males and 442 females, with an age of (56.6±11.1) years (range: 20 to 86 years). Among 335 patients treated with liver transplantation, there were 292 males and 43 females, with an age of (51.0±9.7) years (range: 21 to 73 years). The outcomes of hepatectomy versus liver transplantation, anatomic versus non-anatomic hepatectomy were compared, respectively.Results:Of the 10 966 patients with primary liver cancer, 10 331 patients underwent hepatectomy and 635 patients underwent liver transplantation. Patients with liver resection were categorized into three groups: 1986－1995(712 cases), 1996－2008(3 988 cases), 2009?2019(5 631 cases). The 5‐year overall survival rate was 32.9% in the first group(1986－1995). The 5‐year overall survival rate of resected primary liver cancer was 51.7% in the third group(2009‐2019), among which the 5‐year overal survival rates of hepatocellular carcinoma, intrahepatic cholangiocarcinoma and mixed liver cancer were 57.4%, 26.6% and 50.6%, respectively. Further analysis was performed on 2 549 HCC patients with primary hepatectomy. The 1‐, 3‐, 5‐, and 10‐year overall survival rates were 88.1%, 71.9%, 60.0%, and 41.0%, respectively, and the perioperative mortality rate was 1.0%. Two hundred and forty‐seven HCC patients underwent primary liver transplantation, with 1‐, 3‐, 5‐, and 10‐year overall survival rates of 84.0%, 64.8%, 61.9%, and 57.6%, respectively. Eighty‐eight HCC patients underwent salvage liver transplantation, with the 1‐, 3‐, 5‐, and 10‐year overall survival rates of 86.8%, 65.2%, 52.5%, and 52.5%, respectively. There was no significant difference in survival rates between the two groups with liver transplantation ( P>0.05). Comparing the overall survival rates and recurrence rates of primary hepatectomy (2 549 cases) with primary liver transplantation (247 cases), the 1‐, 3‐, 5‐, and 10‐year overall survival rates in patients within Milan criteria treated with hepatectomy and transplantation were 96.3%, 87.1%, 76.9%, 54.7%, and 95.4%, 79.4%, 77.4%, 71.7%, respectively ( P=0.754). The 1‐, 3‐, 5‐year recurrence rates were 16.3%, 35.9%, 47.6% and 8.1%, 11.7%, 13.9%, respectively( P<0.01). The 1‐, 3‐, 5‐, 10‐year overall survival rates in patients with no large vessels invasion beyond the Milan criteria treated with liver resection and transplantation were 87.2%, 65.9%, 53.0%, 33.0% and 87.6%, 71.8%, 71.8%, 69.3%, respectively( P=0.003); the 1‐, 3‐, 5‐year recurrence rate were 39.2%, 57.8%, 69.7% and 29.7%, 36.7%, 36.7%, respectively ( P<0.01). The 1‐, 3‐, 5‐, and 10‐year overall survival rates in patients with large vessels invasion treated with liver resection and transplantation were 62.1%, 36.1%, 22.2%, 15.0% and 62.9%, 31.8%,19.9%, 0, respectively ( P=0.387); the 1‐, 3‐, 5‐year recurrence rates were 61.5%, 74.7%, 80.8% and 59.7%, 82.9%, 87.2%, respectively( P=0.909). Independent prognostic factors for both overall survival and recurrence‐free survival rates of HCC patients treated with liver resection included gender, neoadjuvant therapy, symptoms, AST, intraoperative or postoperative blood transfusion, tumor number, tumor size, cirrhosis, macrovascular invasion, microvascular invasion, and pathological differentiation. Propensity score matching analysis of 443 pairs further showed that there was no significant difference in overall survival rate between anatomical liver resection and non‐anatomical liver resection( P=0.895), but the recurrence rate of non‐anatomical liver resection was higher than that of anatomical liver resection( P=0.035). Conclusions:In the past decade, the overall survival rate of HCC undergoing surgical treatment is significantly higher than before. For HCC patients with good liver function reservation, surgical resection can be performed first, and salvage liver transplantation can be performed after recurrence. The effect of salvage liver transplantation is comparable to that of primary liver transplantation. As for the choice of liver resection approaches, non‐anatomical resection can reserve more liver tissue and can be selected as long as the negative margin is guaranteed.

Objective: Using ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) and microPET-CT to test the feasibility of ¹⁸F-FDG PET-CT for validation of olfactory function of rats with standard phenethyl alcohol (PEA) and isovaleric acid (IVA) odors stimulation. To verify the possibility of ¹⁸F-FDG PET-CT as a new objective examination method for olfactory function. Methods: Six healthy Sprague-Dawley (SD) male rats were selected with a weight of 250-300 g. First of all, buried food pellet test (BFT) was used to confirm the normal olfactory function of rats. Then in the next 3 days, after the intravenous injection of ¹⁸F-FDG (18 MBq/100 g), awaken rats were placed in a ventilated plexiglas cage for 30 min. Subsequently, pure air (the first day), PEA (the second day) and IVA (the third day) were delivered. After odor stimulation for 30 min, rats were performed by a static PET-CT under anesthesia. Images reconstructed were assessed by SPM method and analyzed by VBM method. Data was analysied by paired t test. Results: Activation regions of rat′s brain after PEA stimulation included bed nucleus and insula. Activation regions of rat′s brain after IVA stimulation included olfactory bulb, anterior olfactory nucleus, amygdala, entorhinal cortex, olfactory cortex, piriform cortex, insula, prefrontal cortex, cingulate cortex and bed nucleus (P<0.005, Ke>20 voxels). Conclusions Through microPET-CT, we can observe that olfactory stimulation with different odors can induce metabolic activation in different regions of rat′s brain, which was in concordance with olfactory regions. The olfactory related brain regions of rats have strong responses to odor stimulation of IVA.

Objective: To explore the clinical effects and the influence factors of olfactory training in the treatment of olfactory dysfunction. Methods: A total of 86 patients with olfactory dysfunction (49 post-infectious and 37 post-traumatic) in Beijing Anzhen Hospital during Dec 2016 to May 2017 were recruited in this prospective study. The clinical data of patients were analyzed, including gender, age, body mass index (BMI), course of disease, smoking history, drinking history, diabetes history, hypertension history, hyperlipidemia history, and anxiety visual analogue score (VAS). All patients were treated with olfactory training for 16 weeks, and all of them underwent Sniffin′ Sticks olfactory test before and after treatment, which was evaluated by composite threshold-discrimination-identification score (TDI). SPSS 23.0 software, paired t test and univariate and multivariate Logistic regression analysis were used to analyze the data. Results: Eighty patients received treatment, including 46 post-infectious olfactory dysfunction and 34 post-traumatic olfactory dysfunction. After olfactory training, the total scores of TDI increased with statistically significant (18.3±8.6 vs 13.6±7.4, t=-6.158, P<0.05). The overall efficacy was 40% (32/80). The effective rate were 45.7% (21/46) in post-infectious olfactory dysfunction and 32.4% (11/34) in post-traumatic olfactory dysfunction respectively, with no statistically significant difference (χ²=1.441, P=0.230). Logistic regression analysis showed that the course of disease was an influence factor in the clinical curative effect (OR=0.881, 95%CI: 0.799-0.973, P=0.012). In patients with less than a year of olfactory dysfunction, the olfactory function improved obviously with the efficiency of 50.9% (29/57). Conclusion Sixteen weeks of olfactory training provides a significant therapeutic effect on the post-infectious and post-traumatic olfactory dysfunction, and the olfactory training can achieve better therapeutic effects at the early stage.

Stress urinary incontinence (SUI) and underactive bladder (UAB) are common types of lower urinary tract dysfunction in women.As the treatment mechanisms of the two conditions are contradictory, the treatment of SUI patients complicated with UAB remains a difficult clinical problem.In order to improve the treatment rate of such patients and promote research, this paper reviews the latest domestic and overseas diagnostic criteria of UAB, summarizes the treatment experience of conventional midurethral sling (tension-free vaginal tape or outside-in transobturator tape) and adjustable sling procedures (transobturator adjustable tape or Remeex system) combined with medication or intermittent catheterization, and the application prospects of cutting-edge technologies such as stem cell injection, cytokine therapy and gene therapy, so as to provide reference for clinicians and researchers.

Transient receptor potential vanilloid-1(TRPV1) channel is a non-selective ligand-gated cationic channel with multiple activation mechanisms in the transient receptor potential subfamily. In recent years, a large number of studies have found that TRPV1 plays an important role in the field of cardiovascular diseases such as hypertension and atherosclerosis. With the in-depth study of traditional Chinese medicine, it has been found that Chinese medicine monomers and their active components can activate or inhibit TRPV1 channels, which has certain potential in the study of cardiovascular diseases. In this paper, the role of TRPV1 channel in cardiovascular diseases and the research progress of traditional Chinese medicine prevention and treatment of cardiovascular diseases based on TRPV1 channel are reviewed, in order to provide new ideas for prevention and treatment of cardiovascular system diseases.
