[Impact of changes in malignant tumor death spectrum on life expectancy in Tianjin residents from 1999-2019].

Objective: To analyze the effects of changes in the spectrum of deaths from malignant tumors on the life expectancies of residents of different ages, sexes, and regions (urban or rural) in Tianjin from 1999 to 2019. Methods: The Abridged Life Table method and the Arriaga's decomposition method were used to calculate the effects of changes in spectrum of deaths from malignant tumors on the life expectancies of Tianjin residents of different ages, sexes, and regions. Results: During 1999-2019, the life expectancies increased by 4.96 years and 5.69 years for males and females, respectively, in Tianjin. The decreases in the mortalities from malignant neoplasms contributed 0.12 year (3.30%) and 0.03 year (0.77%) for males and females, respectively, to the increase during 1999-2007, and 0.05 year (3.13%) and 0.12 year (6.08%) for males and females, respectively, during 2007-2019. The decreases in the mortality rates of malignant tumors contributed the most to the increase among residents in the 60-69 years group, and the decreases in mortality rates of lung, gastric, esophageal, and liver cancers had relatively larger contribution. Lung cancer had a negative effect on the life expectancies of men and rural residents, but a positive effect on those of women and urban residents. The significant increases in the mortality rates of lung, colorectal, and pancreatic cancers in the ≥85 years group had a large negative effect on the overall life expectancy. Breast and ovarian cancers contributed negatively to the life expectancy of female residents. Conclusion: The overall increase in the life expectancy in Tianjin from 1999 to 2019 was mainly attributed to the elderly and the decreases in the mortality rates of gastric, esophageal, and liver cancers, among other malignancies, while the increases in the mortality rates of lung, colorectal, gallbladder, pancreatic, and breast cancers were the most significant factors hindering the increase of the life expectancy in Tianjin.

[Clinical characteristics of children with severe SARS-CoV-2 infection in Yunnan].

Objective: To investigate the clinical characteristics of 130 children with severe SARS-CoV-2 infection in Yunnan province after the relaxation of non-pharmaceutical interventions, and analyze the risk factors for mortality. Methods: This study is a retrospective case summary that analyzed the demographic data, underlying diseases, clinical diagnoses, disease outcomes, and laboratory results of 130 children with severe COVID-19 infections admitted to nine top-tier hospitals in Yunnan Province from December 2022 to March 2023. According to the prognosis, the patients were divided into survival group and death group. The clinical and laboratory data between the two groups were compared, and the risk factors of death were evaluated. The χ2 test and Mann-Whitney U test were employed to compare between groups, while Spearman correlation test and multiple Logistic regression were used to analyze the risk factors for death. The predictive value of independent risk factors was evaluated by receiver operating characteristic curve. Results: The 130 severe patients included 80 males and 50 females with an onset age of 28.0 (4.5, 79.5) months. There were 97 cases in the survival group and 33 cases in the death group with no significant differences in gender and age between the two groups (P>0.05). Twenty-five cases (19.2%) out of the 130 patients had underlying diseases, and the number with underlying diseases was significantly higher in death group than in survival group (36.4% (12/33) vs. 13.4%(13/97), χ2=8.36, P=0.004). The vaccination rate in the survival group was significantly higher than that in the death group (86.1% (31/36) vs. 7/17, χ2=9.38, P=0.002). A total of 42 cases (32.3%) of the 130 patients were detected to be infected with other pathogens, but there was no significant difference in the incidence of co-infection between the death group and the survival group (39.3%(13/33) vs. 29.9% (29/97), χ2=1.02, P>0.05). Among the 130 cases, severe respiratory cases were the most common 66 cases (50.8%), followed by neurological severe illnesses 34 cases (26.2%) and circulatory severe 13 cases (10%). Compared to the survival group, patients in the death group had a significantly higher levels of neutrophil, ferritin, procalcitonin, alanine aminotransferase, lactate dehydrogenase, creatine kinase isoenzyme, B-type natriuretic peptide, interleukin-6 and 10 (6.7 (4.0, 14.0) vs. 3.0 (1.6, 7.0)×109/L, 479 (298, 594) vs. 268 (124, 424) µg/L, 4.8 (1.7, 10.6) vs. 2.0 (1.1, 3.1) µg/L, 66 (20, 258) vs. 23 (15, 49) U/L, 464 (311, 815) vs. 304 (252, 388) g/L, 71(52, 110) vs. 24(15, 48) U/L, 484 (160, 804) vs. 154 (26, 440) ng/L, 43 (23, 102) vs. 19 (13, 27) ng/L, 216 (114, 318) vs. 86 (45, 128) ng/L, Z=-4.21, -3.67, -3.76, -3.31, -3.75, -5.74, -3.55, -4.65, -5.86, all P<0.05). The correlated indexes were performed by multivariate Logistic regression and the results showed that vaccination was a protective factor from death in severe cases (OR=0.01, 95%CI 0-0.97, P=0.049) while pediatric sequential organ failure assessment (PSOFA) (OR=3.31, 95%CI 1.47-7.47, P=0.004), neutrophil-to-lymphocyte ratio (NLR) (OR=1.56, 95%CI 1.05-2.32, P=0.029) and D dimer (OR=1.49, 95%CI 1.00-1.02, P=0.033) were independent risk factors for death (all P<0.05). The area under the curve of the three independent risk factors for predicting death were 0.86 (95%CI 0.79-0.94), 0.89 (95%CI 0.84-0.95) and 0.87 (95%CI 0.80-0.94), all P<0.001, and the cut-off values were 4.50, 3.66 and 4.69 mg/L, respectively. Conclusions: Severe SARS-CoV-2 infection can occur in children of all ages, primarily affecting the respiratory system, but can also infect the nervous system, circulatory system or other systems. Children who died had more severe inflammation, tissue damage and coagulation disorders. The elevations of PSOFA, NLR and D dimer were independent risk factors for death in severe children.

[Evaluation of brain age changes in patients with liver cirrhosis and hepatic encephalopathy with deep learning models based on structural magnetic resonance imaging].

Objective: To investigate the brain aging in patients with cirrhosis and hepatic encephalopathy(HE), constructed a prediction model of brain age based on deep learning and T1 high-resolution MRI, and try to reveal the specific regions where cirrhosis and HE accelerating brain aging. Methods: A cross-sectional study. A brain age prediction model based on the 3D full convolutional neural network was constructed through T1 high-resolution MRI data from 3 609 healthy individuals across eight global public datasets. The mean absolute error (MAE) between actual age and predicted brain age, Pearson correlation coefficient (r) and determination coefficient (R2) were calculated to evaluate the accuracy of the model's predictions. A test set (n=555) from the Human Connectome Project was used to assess the accuracy of the model. A total of 136 patients with cirrhosis were recruited from Tianjin First Central Hospital as the case group (79 patients with cirrhosis without HE and 57 patients with cirrhosis with HE), and 70 healthy individuals were recruited from the society as the healthy control group during the same period. Brain-predicted age difference (Brain-PAD), digital connection-A (NCT-A) and digital-symbol test (DST) scores of all subjects were calculated for all subjects to assess brain aging and cognitive function in the healthy control group, the cirrhosis without HE group, and the cirrhosis with HE group. The network occlusion sensitivity analysis method was employed to assess the importance of each brain region in predicting brain age. Results: As for the prediction model, in the training set, MAE=2.85, r=0.98, R2=0.96. In the test set, MAE=4.45, r=0.96, R2=0.92. In the local data set of the healthy control group, MAE=3.77, r=0.85, R2=0.73. The time of NCT-A in both cirrhosis groups was longer than healthy control group, while the DST scores were lower than healthy control group, and the differences were statistically significant (both P<0.001); the Brain-PAD of healthy control group was (0.8±4.5) years, the Brain-PAD of no-HE group was (6.9±8.1) years, and the HE group was (10.2±7.7) years. The differences between the three groups were statistically significant (P<0.001), and the differences between any two groups were statistically significant (all P<0.05). The importance ratio of visual network in predicting brain age increased in cirrhosis patients, and the HE group was higher than no-HE group. Conclusions: In patients with cirrhosis, the cognitive function is reduced, brain aging is accelerated, and these changes are more obvious in patients with HE. The importance differences of each brain network in predicting brain aging provide a new direction for identifying the specific regions where cirrhosis and HE accelerate brain aging.

[Comparison of efficacy and safety of transurethral thulium laser vapoenucleation of prostate and transurethral thulium laser enucleation of prostate in the treatment of benign prostatic hyperplasia].

Objective: To compare early outcomes between transurethral thulium laser vapoenucleation of prostate and transurethral thulium laser enucleation of prostate for the treatment of benign prostatic hyperplasia (BPH). Methods: Retrospective analysis was conducted on the clinical data of 1 638 BPH patients admitted to the Department of Urology of Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January 2018 to December 2021. There were 916 patients underwent transurethral thulium laser vapoenucleation of prostate (ThuVEP group) and 722 patients underwent transurethral thulium laser enucleation of prostate (ThuLEP group). The operation time, eliminated tissue weight, surgical complications, duration of post-operative catheter implantation were compared between the two groups. The improvement of International Prostate Symptom Score (IPSS), Quality of Life Index (QoL), maximum uroflow rate (Qmax) and post-void residual urine volume (PVR) at 1 month after operation was compared between the two groups. Results: There were no significant differences in age, preoperative and 1-month postoperative prostate volume, IPSS score, QoL score, Qmax, and PVR between the ThuVEP and ThuLEP group (all P>0.05). There were no significant differences in perioperative indicators such as operation time, cutting or enucleation time, tissue crushing time, tissue weight, hemoglobin change, catheter indwelling time, and postoperative hospital stay between ThuVEP group and ThuLEP group (all P>0.05). The incidence of minor gross hematuria after extubation in the ThuVEP group was 7.8% (56/916), which was lower than 9.4% (65/722) in the ThuLEP group (P=0.026); the incidence of temporary incontinence at 1 month after surgery was 5.2% (38/916) in ThuVEP group, lower than 11.9% (86/722) in ThuLEP group (P<0.001). A total of 3 patients (0.4%) in ThuLEP group required operative intervention for severe post-operation bleeding, but none of ThuVEP group suffered from this kind of surgical complications. Conclusions: ThuVEP has similar efficacy with ThuLEP for the treatment of BPH. ThuVEP can significantly reduce the incidence of post-operation temporary urine incontinence, and has much superiority in stanching bleeding.

[Research progress on cirrhosis reversal and recompensation].

Previously, liver lesions in cirrhosis were considered irreversible, especially because the condition aggravated gradually after entering the decompensated phase, thus making it difficult to return to the compensated phase. At present, more and more evidence shows that some patients with decompensated liver cirrhosis can be recompensated after the cause is controlled and complications are managed. This article explores the research progress related to LC reversal and recompensation from three aspects: liver histopathology, liver function, and clinical complications.

[Clinical and genetic characteristics of young patients with myeloproliferative neoplasms].

Objectives: To investigate the clinical and genetic features of young Chinese patients with myeloproliferative neoplasms (MPN). Methods: In this cross-sectional study, anonymous questionnaires were distributed to patients with MPN patients nationwide. The respondents were divided into 3 groups based on their age at diagnosis: young (≤40 years) , middle-aged (41-60 years) , and elderly (>60 years) . We compared the clinical and genetic characteristics of three groups of MPN patients. Results: 1727 assessable questionnaires were collected. There were 453 (26.2%) young respondents with MPNs, including 274 with essential thrombocythemia (ET) , 80 with polycythemia vera (PV) , and 99 with myelofibrosis. Among the young group, 178 (39.3%) were male, and the median age was 31 (18-40) years. In comparison to middle-aged and elderly respondents, young respondents with MPN were more likely to present with a higher proportion of unmarried status (all P<0.001) , a higher education level (all P<0.001) , less comorbidity (ies) , fewer medications (all P<0.001) , and low-risk stratification (all P<0.001) . Younger respondents experienced headache (ET, P<0.001; PV, P=0.007; MF, P=0.001) at diagnosis, had splenomegaly at diagnosis (PV, P<0.001) , and survey (ET, P=0.052; PV, P=0.063) . Younger respondents had fewer thrombotic events at diagnosis (ET, P<0.001; PV, P=0.011) and during the survey (ET, P<0.001; PV, P=0.003) . JAK2 mutations were found in fewer young people (ET, P<0.001; PV, P<0.001; MF, P=0.013) ; however, CALR mutations were found in more young people (ET, P<0.001; MF, P=0.015) . Furthermore, mutations in non-driver genes (ET, P=0.042; PV, P=0.043; MF, P=0.004) and high-molecular risk mutations (ET, P=0.024; PV, P=0.023; MF, P=0.001) were found in fewer young respondents. Conclusion: Compared with middle-aged and elderly patients, young patients with MPN had unique clinical and genetic characteristics.

[Real-world data analysis of 3012 patients undergoing laparoscopic radical gastrectomy in a single center over the past 12 years].

Objective: To Summarize the safety, clinical outcome and technical evolution of laparoscopic gastric cancer surgery. Methods: A retrospective cohort study was carried out. Clinical data of 3012 patients who underwent laparoscopic radical gastrectomy for gastric cancer from January 2010 to March 2022 at Department of General Surgery, the First Affiliated Hospital of Nanjing Medical University were retrospectively collected and analyzed. Case inclusion criteria were gastric malignancies confirmed by pathology, without distant metastasis by examination before operation and exploration during operation, patients undergoing laparoscopic radical gastrectomy, intact function of important organs and with complete data. Exclusion criteria were patients who underwent emergency gastric cancer resection due to gastric bleeding, perforation or obstruction, etc., tumor found to invade adjacent organs such as pancreas or transverse colon during the operation, conversion to open surgery during the operation, those who had other malignant tumors (except thyroid cancer) within 5 years, and those had severe cardiopulmonary, liver, or kidney insufficiency before surgery. Outcomes included: (1) baseline information of patients; (2) trend of the quantity of laparoscopic radical gastrectomy year by year; (3) evolution of the mode of digestive tract reconstruction; (4) periopertive outcome short-term complication was defined as complication occurring within 30 days after operation and classified accordiny to the clavien-Dindo criteria; and (5) 5-year overall survival. SPSS software was used for statistical analysis. Continuous variables that obeyed the normal distribution were expressed in the form of Mean±SD. Days of hospital stay that did not follow a normal distribution were expressed as median (Q1,Q3), and the Mann-Whiney U test was used for comparison. Discrete variables were expressed as cases (%), and chi-square test or rank sum test was used for comparison between groups. Linear regression analysis was used to analyze the relationship between the amount of surgery and the year of surgery. Kaplan-Meier method and log-rank test were used for survival analysis. Two-tailed P<0.05 was considered as statistically significant. Results: Among the 3012 cases, 2114 were male and 898 were female. The patients' average age at surgery was (61.1±10.7) years old. According to the number of cumulative cases, the patients were divided into three groups: early, intermediate and late, with 1004 patients in each group. The early group consisted of patients undergoing operation from January 2010 to October 2018, the intermediate group consisted of patients undergoing operation from October 2018 to January 2021, and the late group consisted of patients undergoing operation from January 2021 to March 2022. (1) General information: There were 691 (68.8%), 699 (69.6%) and 724 (72.1%) male patients in early, intermediate and late groups respectively; the average age increased from 56.6 years in 2010 to 62.8 years in March 2022. As for the tumor stage T1, T2, T3, T4, there were 49.0%, 14.4%, 23.9% and 12.6% in the early group; 47.5%, 12.9%, 26.9% and 12.6% in the intermediate group; 39.7%, 14.6%, 30.0%, and 15.6% in the late group, respectively. Patients with N0, N1, N2, N3a, N3b stage were 56.8%, 13.7%, 13.4%, 11.0%, and 5.0% in the early group; 55.7%, 12.9%, 12.8%, 11.6%, and 6.9% in the intermediate group; 51.0%, 16.1%, 12.8%, 12.5%, and 7.5% in the late group, respectively. (2) Year-by-year change in the number of gastric cancer operations: From 19 cases per year in 2010 to 786 per year in 2021, the annual number of gastric cancer operations was proportional to the year of operation (y=47.505x, R2=0.67). The proportion of patients with stage I disease showed a fluctuating downward trend over time, while the proportion of patients with stage III disease increased slightly, accounting for 34% until March 2022. (3) Evolution of digestive tract reconstruction methods: Except in 2010, the digestive tract reconstruction method of distal gastrectomy focused on Billroth-II+Braun anastomosis among patients undergoing laparoscopic gastric cancer surgery in other years, whose proportion had gradually increased from less than 20% in 2016 to about 70% after 2021; the gastrointestinal reconstruction methods after total gastrectomy had gradually increased in π anastomosis and overlap anastomosis since 2016, of which π anastomosis reached about 65% in 2019, and overlap anastomosis reached almost 30% in 2020; the anastomosis methods after proximal gastrectomy had been mainly double-channel anastomosis (54%) and esophagogastric anastomosis (30%) since 2016, and double-channel anastomosis accounted for up to 70% in 2019. (4) Operation time: The operation time of early, intermediate and late group was (193.3±49.8) min, (186.9±44.3) min and (206.7±51.4) min respectively. Intermediate group was significantly shorter than early group (t=3.005, P=0.003), while late group was significantly longer than early group (t=5.875, P<0.001) and intermediate group (t=9.180, P<0.001). (5) Postoperative hospital stay: The median length of hospital stay for gastric cancer patients in early, intermediate and late groups was 9 (8, 11) d, 8 (7, 10) d, and 8 (7.5, 10) d respectively. The postoperative hospital stay of intermediate group and late group was significantly shorter than that of early group (Z=-12.467, Z=-5.981, both P<0.001), but there was no significant difference between intermediate group and late group (Z=0.415,P=0.678). (6) Postoperative complication: The morbidity of short-term complication in early, intermediate and late group was 20.4% (205/1004), 16.2% (163/1004), and 16.2% (162/1004) respectively, and above morbidity of intermediate group and late group was significantly lower than that of early group (χ2=5.869, P=0.015; χ2=6.165, P=0.013), while there was no significant difference between intermediate group and late group (χ2=0.004,P=0.952). The morbidity of short-term complication of grade IIIor higher was 8.0% (80/1004), 7.6% (76/1004), and 4.9% (49/1004) in early, intermediate and late group respectively, and above morbidity of late group was significantly lower than that of early and intermediate group (χ2=7.965, P=0.005; χ2=6.219,P=0.013), while there was no significant difference between intermediate group and early group (χ2=0.111,P=0.739). (7) Survival analysis: The follow-up deadline for survival data was December 31, 2021, and the median follow-up time was 29.5 months. The overall 5-year survival rate of all the patients was 74.7%. The 5-year survival rates of stage I, II and III patients were 92.0%, 77.2%, and 40.3% respectively and 5-year survival rates of patients with stage IA, IB, IIA, IIB, IIIA, IIIB and IIIC were 93.2%, 87.8%, 81.1%, 72.7%, 46.2%, 37.1%, and 34.0% respectively. Conclusions: The number of laparoscopic gastric cancer operation in our center is increasing year by year. With the maturity of laparoscopic technology, the morbidity of complication in laparoscopic gastric cancer surgery is decreasing.

Probing

The isomer depletion of ^{93m}Mo was recently reported [Chiara et al., Nature (London) 554, 216 (2018)NATUAS0028-083610.1038/nature25483] as the first direct observation of nuclear excitation by electron capture (NEEC). However, the measured excitation probability of 1.0(3)% is far beyond the theoretical expectation. In order to understand the inconsistency between theory and experiment, we produce the ^{93m}Mo nuclei using the ^{12}C(^{86}Kr,5n) reaction at a beam energy of 559 MeV and transport the reaction residues to a detection station far away from the target area employing a secondary beam line. The isomer depletion is expected to occur during the slowdown process of the ions in the stopping material. In such a low γ-ray background environment, the signature of isomer depletion is not observed, and an upper limit of 2×10^{-5} is estimated for the excitation probability. This is consistent with the theoretical expectation. Our findings shed doubt on the previously reported NEEC phenomenon and highlight the necessity and feasibility of further experimental investigations for reexamining the isomer depletion under low γ-ray background.

[Clinical characteristics of 500 hospitalized patients with liver cirrhosis: a retrospective analysis from a tertiary hospital in Beijing].

Objective: To understand the clinical characteristics of hospitalized patients with liver cirrhosis, so as to provide theoretical basis for disease diagnosis and treatment, formulation of intervention measures, and improve the level of disease diagnosis and treatment. Methods: Hospitalized patients who were initially diagnosed with liver cirrhosis at Peking University First Hospital from August 2017 to December 2018 were selected retrospectively as the research objects. Liver cirrhosis demographic data, etiology, severity classification, incidence of complications, diagnosis and prognosis were recorded. Statistical analysis was performed using SPSS software. Results: Among all liver cirrhosis cases, there were 291 males and 209 females, with a male-to-female ratio of 1.4:1 and an age of 59.5±12.9 years as at August 2017 to December 2018. HBV infection, alcoholic liver disease, and autoimmune liver diseases were the most common etiology of liver cirrhosis. HBV infection alone, HBV infection combined with other factors, alcoholic liver disease alone, alcoholic liver disease combined with other factors, autoimmune liver disease alone, and autoimmune liver disease combined with other factors were presented in 163 (32.6%), 57 (11.4%), 47 (9.4%), 63 (12.6%), 85 (17.0%), and 22 (4.4.0%) cases, respectively. Ascites (221 cases, 44.2%), followed by esophagogastric varices (214 cases, 42.8%), and other including hypersplenism (137 cases), liver cancer (126 cases), upper digestive system tract hemorrhage (66 cases), hepatic encephalopathy (40 cases), infection (37 cases), portal vein thrombosis (23 cases), hepatorenal syndrome (20 cases) were the most common complications. The most common site of infection was the abdominal cavity (20 cases), accounting for 54.1%; followed by respiratory tract infection (8 cases), accounting for 21.6% in patients with liver cirrhosis with concurrent infection. Among them, there were 32 cases of bacterial infection alone, one case of bacterial infection combined with fungal infection, one case of bacterial infection combined with viral infection, and three cases of unknown pathogens. There were 69 cases in Child Pugh grade C, and the average hospitalization times were 12.6 days in terms of prognosis. There were total seven cases of death, of which five cases were due to upper gastrointestinal hemorrhage and two due to hepatic encephalopathy. Conclusion: HBV infection, ascites, and upper gastrointestinal bleeding were the most common etiologies, complications, and causes of death in patients with liver cirrhosis at our hospital.

[Considerations on expanding the indications for antiviral therapy from the perspective of staging of chronic hepatitis B virus infection].

Patients with chronic (hepatitis B virus,HBV) infection can be divided into immunotolerant, immunoclearance (HBeAg-positive, immune-active), immunocontrol (inactive), and reactivation (HBeAg-negative, immune-active) phases according to HBV serological markers, HBV DNA, alanine aminotransferase, and liver pathology results. Chronic HBV infection is considered indeterminate when the above four phasing criteria are not met. The Chinese "Guidelines" recommend antiviral B treatment for chronic HBV-infected patients with elevated alanine aminotransferase levels after excluding other potential causes. As a result, patients with chronic HBV infection in the immunoclearance and reactivation phases are included in the indication population for antiviral therapy, and the expanded indications are mainly for other infected individuals beyond these two phases: immunotolerant, immunocontrol, and indeterminate. Antiviral therapy may benefit individuals in an indeterminate phase, because they are at a relatively high risk of disease progression.

[Clinical features of Epstein-Barr virus infection associated to liver injury in adolescents and adults].

Epstein-Barr virus (EBV) infection is closely associated to liver injury with diverse clinical features in adolescents and adults. It is often manifested as infectious mononucleosis syndrome, sometimes causing self-limited acute hepatitis, with mild to moderate elevation of liver transaminases, and relative increase in age-related conditions. EBV infection can also cause cholestatic hepatitis, with elevated alkaline phosphatase and γ-glutamyltransferase as the main manifestations, accompanied by varying degrees of jaundice. A small number of patients with severe EBV infection may experience liver failure, and if left untreated in time, it may lead to high mortality. In addition, EBV infection is also associated with chronic hepatitis, liver cirrhosis, autoimmune liver disease, etc.

[Emphasizing the clinical diagnosis and treatment of liver disease-associated infections].

Liver disease-associated infection is a common condition in clinic. The existence of underlying liver disease increases the morbidity, mortality, and other adverse consequences of various infections, which in turn aggravates the liver disease-associated infections progression. Therefore, liver disease and infection should be emphasized in the clinical management. The assessment of liver disease includes its etiology, severity level, and complications, while the assessment of infectious diseases emphasizes its etiology and lesion location. Timely elimination of pathogens and complications is the treatment aspect of liver disease, whereas empiric pathogenic therapy is the treatment aspect of infection. The use of anti-infective drugs with a high risk of liver damage should be avoided when the pathogen is determined, and the target should be treated as soon as possible.

[Research progress and prospect of liver cirrhosis].

Liver cirrhosis is the final stage of many chronic liver diseases, and is still a heavy disease burden. The proportion of liver cirrhosis caused by the hepatitis B virus is declining, while that caused by the non-alcoholic fatty liver disease (metabolic-associated fatty liver disease) is rising. Several predictive models and techniques such as transient elastography have been used for the early non-invasive evaluation of liver cirrhosis. Effective etiological treatment and complication management are the possible key to reverse and recompense liver function during liver cirrhosis treatment. In recent years, the effectiveness and availability of anti-hepatitis B and C virus drugs have been significantly improved, which provides the basis for effective etiological treatment of liver cirrhosis. However, there is still a lack of etiological treatment measures for non-alcoholic fatty liver disease. Therefore, in addition to focusing on common complications, we should also manage "rare" complications. This article reviews the changes in epidemiological characteristics, the update of the natural history concepts, diagnostic evaluation methods, and the treatment measures for liver cirrhosis.

[Retrospective analysis of risk factors of liver cirrhosis combined with overt hepatic encephalopathy: a single -center case-control study].

Objective: To explore the risk factors of overt hepatic encephalopathy (OHE) in patients with liver cirrhosis. Methods: A retrospective study was designed. Patients with liver cirrhosis combined with /without OHE who were hospitalized to our hospital during the same period were selected as the case/control group. Clinical and laboratory data of both groups of patients were compared to analyze the risk factors affecting the occurrence of OHE. SPSS software was used for statistical analysis. A t-test or rank-sum test was used to compare the measurement data. Chi-square test or Fisher's exact probability method was used to compare the count data. Logistic regression was used for multivariate analysis. Results: A total of 500 patients with liver cirrhosis diagnosed in our hospital from August 2017 to December 2018 were selected as the case group, and 40 cases with cirrhosis without OHE who were hospitalized during the same period were randomly selected as the control group. The gender composition and age of the case and control group were comparable. Viral hepatitis (mainly hepatitis B) was the main etiology of liver cirrhosis in both groups. There were 52.5% patients in the case group and 57.5% patients in the control group, respectively. Alcoholic liver disease, autoimmune liver disease and so on were the other included causes. With regard to blood biochemical indicators, the serum creatinine levels of both groups were comparable, but in the case group, the serum total bilirubin level was higher (34.30 µmol / L vs. 18.65 µ mol/L, Z = -3.185, P < 0.05), while the serum sodium level was lower (137.00 mmol/L vs. 140.08 mmol/L, Z = -2.348, P < 0.05), and the prothrombin time was longer (14.60 s vs. 12.20 s) s. 078, P < 0.05), and international normalized ratio (1.33 vs. 1.07, Z = - 5.632, P < 0.05), and serum albumin level (30.6 g/L vs. 35.6 g/L, t = 3.386, P < 0.05) was lower. In terms of complications, patients in the case group had a higher proportion of combined gastrointestinal bleeding (30.0% vs. 10.0%, χ(2) = 5.000, P < 0.05), ascites (87.5% vs. 30.0%, χ(2) = 27.286, P < 0.05) and secondary infection (32.5% vs. 10.0%, χ(2) = 7.813, P < 0.05). In terms of severity classification, the proportion of Child-Pugh C in the case group was higher (62.5% vs. 10.0%, χ(2) =26.593, P < 0.05). In terms of outcome, there were 3 deaths in the case group and no deaths in the control group. Multivariate analysis showed that Child-Pugh class C (OR = 12.696), and combined ascites (OR = 10.655) were an independent risk factor for OHE in patients with liver cirrhosis. Conclusion: Our single-center retrospective clinical study shows that patients with cirrhosis combined with OHE are more critical and have more complications. In order to promptly diagnose and treat OHE, more attention should be paid to patients with combined ascites and Child-Pugh class C.

[Health-related quality of life and its associated variables in Chinese patients with Philadelphia-negative myeloproliferative neoplasms].

Objectives: To explore health-related quality of life (HRQoL) and identify its associated variables in Chinese patients with Philadelphia-negative myeloproliferative neoplasms (MPNs) . Methods: In this cross-sectional study, anonymous questionnaires were distributed to adult patients with MPNs to assess symptom burden measured by MPN-10 and HRQoL measured by Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) . Results: The data from 1405 respondents with MPNs, including 645 (45.9%) with essential thrombocythemia (ET) , 297 (21.1%) with polycythemia vera (PV) , and 463 (33.0%) with myelofibrosis (MF) , were analyzed. 646 (46.0%) respondents were male. The median age was 56 (range, 18-99) years. The mean MPN-10 scores were 13.0±12.7, 15.0±14.7, and 21.0±16.6 (P<0.001) , and the physical component summary (PCS) and mental component summary (MCS) scores were 48.0±8.5, 47.0±9.0, and 42.0±10.0 (P<0.001) and 51.0±11.0, 50.0±10.8, and 49.0±11.1 (P=0.002) for respondents with ET, PV, and MF, respectively. Respondents with MF reported the lowest score of physical functioning, role functioning, emotional functioning, cognitive functioning, social function, and global health status (all P<0.01) and the highest score of fatigue, pain, dyspnea, appetite loss, diarrhea, and financial problems (all P<0.05) in EORTC QLQ-C30. Multivariate analyses revealed that higher MPN-10 scores were significantly associated with lower PCS (-0.220 to -0.277, P<0.001) and MCS (-0.244 to -0.329, P<0.001) scores; increasing age (-1.923 to -4.869; all P<0.05) , lower PCS score. Additionally, comorbidity (ies) , symptom at diagnosis, splenomegaly, anemia, unknown driver gene, and higher annual out-of-pocket cost were significantly associated with lower PCS and/or MCS scores. However, age ≥ 60 years, urban household registration, concomitant medication, and receiving ruxolitinib therapy in respondents with MF were associated with higher MCS scores. Weak correlations were found between MPN-10 score (except the subscale of appetite loss and constipation) and EORTC QLQ-C30 score in majority of subscales in respondents with ET (|r| = 0.193-0.457, all P<0.001) , PV (|r| = 0.192-0.529, all P<0.01) , and MF (|r| = 0.180-0.488, all P<0.001) , respectively. Conclusions: HRQoL in patients with MPN was significantly reduced, especially in patients with MF. Sociodemographic and clinical variables were significantly associated with the HRQoL in patients with MPNs.

[Effect of customized zirconia abutment on peri-implant tissue: a one-year prospective study].

Objective: To observe the changes of peri-implant tissue around the individualized abutment that was grinded from zirconia provisional crown in one year. Methods: In this research, a prosthodontic-driven virtual implant planning and immediate provisionalization were conducted in computer assisted design software. And computer-aided design/computer-aided manufacturing (CAD/CAM) techniques were used to fabricate the zirconia provisional crown and surgical guide template before surgery. The implant was accurately placed with the surgical guide, and the zirconia provisional crown was immediately delivered after surgery. Three months later, the implant osseointegration was completed, and zirconia provisional crown was prepared intraorally to generate customized zirconia abutment for final prosthesis. The study included 30 patients with single anterior tooth loss, including 18 males and 12 females, aged from 26 to 50 years old, and the mean age was (36.2±6.1) years old. The patients were from the Center of Oral Implantology, The First Affiliated Hospital of Zhejiang University Medical College from January 2017 to February 2018. After cementation of the final prosthesis, the cases were followed up at 6 and 12 months time intervals. Implant survival rate, probing depth, bleeding on probing, marginal bone level loss and papilla index score (PIS) were recorded in every appointment. Results: The survival rate of 30 implants was 100%, and the probing depths were less than 5 mm. The bone resorption at 6 and 12 months follow-up after the final delivery was 0 (0, 0) mm and 0 (-0.2, 0) mm, respectively, and the difference was not statistically significant (P>0.05). The PIS was 3.0 (2.0, 4.0), 3.0 (2.8, 4.0) and 3.0 (3.0, 4.0) on the final delivery, 6 and 12 months after final delivery, respectively. Conclusions: Marginal bone level and bone loss were stable with this new implant clinical protocol at the one-year follow-up.

[A case of cerebral infarction after deep burn tangential excision and skin grafting].

A female patient aged 42 years with deep burn on right lower limb was admitted to Affiliated Hospital of Jining Medical University on January 25, 2019. The patient previously had cerebral infarction, hypertension, and hysteria, with long-term use of aspirin and risperidone. After admission, the patient underwent tangential excision twice. On the third day after the second tangential excision and skin grafting, the muscle strength of the right limb gradually decreased, and the patient was treated with emergency craniocerebral magnetic resonance imaging, which suggested acute cerebral infarction. Improvement of cerebral circulation and vasodilatation were given immediately. The limb muscle strength of the patient gradually recovered on the fifth day after the operation, and no sequela was left when the patient was discharged. After the case was discussed, we think that postoperative decreased blood volume and blood concentration resulting from tangential excision bleeding of deep burn and wound exudate as well as inadequate fluid infusion are the main causes of hemodynamic change, the patient had the basis of multiple cerebral artery stenosis, and superposition of multiple factors led to the occurrence of postoperative acute cerebral infarction. Appropriate increase in the fluid infusion volume during and after surgery and transfusion if necessary to increase blood and oxygen supply to the brain can reduce the occurrence of cerebral infarction.

[Present situation and prospect of diagnosis and treatment of rare complications of liver cirrhosis].

Liver cirrhosis can lead to a variety of complications, among which few are relatively rare or overlooked despite being more common, and are thus termed "rare complications". However, these complications also affect the patient's prognosis, and need attention. This article summarizes the relevant content of the present concept of diagnosis and treatment of rare complications of liver cirrhosis, and prospects the future direction of clinical research.
