ABSTRACT

Objective To evaluate the efficacy of perioperative use of tigecycline in preventing infection and the incidence of hypofibrinogenemia in liver transplant recipients. Methods Clinical data of 40 liver transplant recipients given with tigecycline to prevent infection were retrospectively analyzed. The incidence of infection in recipients and donor-derived infection were analyzed. The changes of clinical indexes in recipients during, upon the completion and (7±2) d after tigecycline treatment were analyzed, respectively. The incidence and treatment of hypofibrinogenemia were summarized. Results Among 40 liver transplant recipients, 2 cases were infected by aspergillus niger and cytomegalovirus, out of the antibacterial spectrum of tigecycline. After adjusting the anti-infection regimen, the infection was properly controlled. Liver allografts were positive for relevant culture in 9 cases, whereas none of them progressed into donor-derived infection. Approximately at postoperative 2 weeks, all 40 recipients restored liver function and were discharged from hospital. Among them, 6 recipients developed hypofibrinogenemia complicated with coagulation disorder at postoperative 2-4 d, whereas transaminase level, bilirubin level and infection-related indexes were gradually decreased after liver transplantation, and albumin level was stable. After supplemented with human fibrinogen and prothrombin complex, coagulation function was improved, but fibrinogen level persistently declined. After terminating use of tigecycline, fibrinogen level was gradually restored to normal range, which might be an adverse drug reaction induced by tigecycline. Conclusions Perioperative anti-infection regimen including tigecycline may reduce the incidence of infection caused by sensitive bacteria in liver transplant recipients. Nevertheless, the incidence of hypofibrinogenemia should be intimately monitored throughout the use of tigecycline.

ABSTRACT

Objective To investigate the epidemiological characteristics of major kidney disease deaths and the potential years of life lost among residents in Wuhan from 2014 to 2019, and to provide a scientific basis for the prevention and treatment of kidney diseases. Methods The major kidney diseases deaths among residents in Wuhan during 2014-2019 were collected from the population-based Mortality Surveillance System. The standardized mortality rate and potential years of life lost rate (PYLLR) of major kidney diseases among residents in different ages and genders were calculated, and the epidemiological characteristics and trends were analyzed. Results There were 4 100 deaths (2 380 in male and 1 720 in female) from major kidney diseases among residents in Wuhan between 2014 to 2019, with an age-standardized mortality rate of 6.22/100 000. The mortality rate of major kidney diseases showed an upward trend with the increasing age groups. The age-standardized mortality rate and the age-standardized potential years of life lost rate (SPYLLR) in glomerular disease and tubulo-interstitial diseases were significantly decreased (P<0.05). The age-standardized mortality rate of the kidney failure was significantly increased (P<0.05), especially in the male (APC=25.10% , P<0.05). Conclusion From 2014 to 2019, there was no significant change in the overall mortality rate of major kidney diseases among residents in Wuhan. The death burden and disease burden of glomerular diseases and tubulo-interstitial diseases were significantly decreased, while the mortality rate of male kidney failure was significantly increased, indicating the need for targeted prevention and treatment of kidney diseases.

ABSTRACT

BackgroundDepression is a kind of disease with relatively high suicide risk, which seriously affects the quality of life of patients and their families, and brings a great burden to society. Antidepressants in western medicine are effective, but the improvement of depressive symptoms is relatively limited by single use, and the combination of two antidepressants may increase the risk of adverse reactions in patients. The rational use of Chinese patent medicine and western medicine may play a complementary role, and the safety of Chinese patent medicine is high. ObjectiveTo explore the early clinical efficacy of fluoxetine combined with Shugan Jieyu capsule in the treatment of depression, and to compare the differences in efficacy, safety and influence on heart rate variability between fluoxetine combined with Shugan Jieyu capsule and fluoxetine alone, so as to provide references for clinical medication of depression patients. MethodsFrom December 2015 to June 2016, 64 patients who met the diagnostic criteria of depression in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) who were hospitalized in the Second Affiliated Hospital of Xinxiang Medical University were selected as the research objects, and were randomly divided into the combined medication group and the fluoxetine group with 32 patients in each group. Patients in both groups were treated with fluoxetine, while patients in the combined medication group were treated with Shugan Jieyu capsule on this basis. Patients in both groups were assessed with Hamilton Depression Scale-24 item (HAMD-24), Hamilton Anxiety Scale (HAMA) and Heart Rate Variability (HRV) before treatment, and were assessed with HAMD-24 and Treatment Emergent Symptom Scale (TESS) at the end of the 2nd, 4th and 6th week of treatment, and HRV was analyzed again at the end of the 6th week of treatment. ResultsThe study ultimately included 60 patients with depression, with 30 cases in the combination therapy group and 30 cases in the fluoxetine group. At the end of the 2nd, 4th and 6th week of treatment, the HAMD-24 score of the combined drug group was lower than that of the fluoxetine group (t=-2.677, -3.960, -4.432, P<0.05 or 0.01). Compared with before treatment, the 24-hour mean standard deviation of normal RR intervals (SDNN), normal low frequency (nLF) and normal high frequency (nHF) in the combined treatment group were higher at the end of the 6th week (t=-73.970, -31.878, -38.721, P<0.01), but significant lower in LF/HF (t=3.525, P<0.01). At the end of the 6th week of treatment, the total effective rate of the combined treatment group was higher than that of fluoxetine group, and the difference was statistically significant (86.67% vs. 70.00%, χ2=18.764, P<0.01). At the 2nd, 4th and 6th week of treatment, there was no significant difference in the number of adverse reactions between the two groups (P>0.05). ConclusionCompared with fluoxetine alone, Shugan Jieyu capsule combined with fluoxetine may be better in clinical efficacy and improvement of heart rate variability in patients with depression, without increasing adverse reactions.

ABSTRACT

In 2022, World Health Organization (WHO) launched the 5th edition of the classification of renal tumors. This classification continues to use the previous classification framework of renal tumors based on morphology and tissue structure, and proposes the concept of renal cell carcinoma defined by molecular features for the first time. This article interprets from the 3 aspects of historical changes of WHO classification and grading of renal tumors, comparison of 2022 and 2016 WHO classification of renal tumors, and the role of molecular characteristics in the new pathological types such as ELOC mutant renal cell carcinoma, ALK rearrangement renal cell carcinoma, eosinophilic solid and cystic renal cell carcinoma. The purpose is to better understand the WHO from the traditional classification system based on tissue morphology to a three-in-one integrated classification system covering morphology, immunophenotype and genetic characteristics, and to understand the important value of molecular pathology in guiding the work of pathologists and clinicians under the new classification system.

ABSTRACT

Objective:To investigate and analyze the influencing factors of teachers' teaching input status on teaching effect satisfaction in medical colleges.Methods:A total of 782 teachers of basic medicine and clinical medicine in a local medical college in Hebei Province were selected by multi-stage stratified random sampling method. The (mean ± standard deviation) was used to describe the status quo of teachers' teaching input, and the t- or F-test was used for inter-group comparison. The influence of teaching input on teaching satisfaction was analyzed by multiple linear regression. Results:The teaching input of medical college teachers was affected by different demographic characteristics, among which the teaching time input was affected by gender, age, professional title, teaching age, educational background and category (all P<0.05), the emotional input was affected by age,professional title,teaching age,educational background and category (all P<0.05), and the teaching ability development input was affected by age, professional title, teaching age and category (all P<0.05). There was a correlation between the population characteristics of teachers and the teaching input and the satisfaction of teaching effect, and the teaching age of teachers is negatively correlated with the satisfaction of teaching effect ( β=-0.057, P<0.05). There were positive correlations between teaching satisfaction and teaching effect (all P<0.05), including the number of lesson preparation hours, the number of weekly teaching hours, the degree of teaching attention, the degree of medical teaching research balance, the learning and expansion of teaching skills, and the difference of teaching observation reflecting teaching input. The teaching input of basic medicine teachers was significantly higher than that of clinical teachers (all P<0.05). Conclusion:It is suggested that medical colleges and clinical teaching bases should pay attention to the construction of teacher echelon, optimization of policies and measures to balance the relationship between medical education and research, construction of the support system of teachers' teaching work input to improve teachers' professional efficacy, and the building of a professional development community of teachers integrating basic medical teachers and clinical teachers to improve the training quality of medical students.

ABSTRACT

Objective:To analyzed clinical characteristics of pituitary growth hormone(GH) adenomas patients with different responses to oral glucose inhibitory GH test.Methods:The clinical data of 50 patients with pituitary GH adenomas newly diagnosed with complete test data and case data in the Department of Endocrinology of Chinese PLA General Hospital was retrospectively analyzed from 2016 to 2021. The cases were divided into two groups according to the cutoff point of GH elevating to 50% of basaline during oral glucose test: abnormal elevation group(A group, n=16) and non-elevation group(B group, n=34). The clinical features, biochemistry, iconography, and immunohistochemistry of the two groups were analyzed. Results:The serum total cholesterol(TC)[(3.9±0.8) vs (4.6±0.9)mmol/L], 120 minutes insulin after glucose loading [11.2(4.4, 25.0) vs 92.0(10.8, 311.8)mU/L], long [1.0(0.4, 2.1) vs 1.5(0.5, 7.3) cm] and short[0.6(0.3, 1.3) vs 1.0(0.5, 5.8)cm] diameters of adenomas in A group were less than those in B group(all P<0.05) while insulin-like growth factor Ⅰ(IGF-Ⅰ) level was higher [(908.2±233.7) vs (743.1±273.1) ng/mL, P<0.05]. There were no significant differences in sex, age, disease course, clinical features, random GH, homeostasis model assessment of insulin resistance index(HOMA-IR), pituitary adenoma site, and invasive properties between the two groups. The immunohistochemical positive rates of ACTH(33% vs 0%) and prolactin(100% vs 28.6%)in A group were higher than those in B group( P<0.05). Conclusion:Pituitary GH adenomas patients with a paradoxical GH response pattern display lower serum TC and 120 minutes insulin levels as well as higher IGF-Ⅰ concentration and proportion of pituitary microadenomas. " Pure" growth hormone tumors may represent entities of a particular class of diseases in acromegaly.

ABSTRACT

In recent years, although the quantity of organ donation after citizen's death has been constantly increased, a large number of patients with end-stage renal diseases are waiting for kidney transplantation every year. The imbalance between donor and recipient is still one of the main problems affecting kidney transplantation in clinical practice. Therefore, it is of clinical significance to accurately evaluate the quality of donor kidney and fully utilize the expanded criteria donor kidney. Contrast-enhanced ultrasound has been gradually applied in the detection of multiple solid organs due to its safety, portability, real-time detection, quantification and other characteristics, and it also has promising application prospect in the evaluation of donor kidney quality. In this article, the advantages and limitations of current evaluation methods for donor kidney and current status and advantages of contrast-enhanced ultrasound in donor kidney evaluation were reviewed, and the application prospect of contrast-enhanced ultrasound in the evaluation of donor kidney quality was discussed, aiming to increase the methods and enhance the accuracy for donor kidney evaluation, and provide reference for rational use of expanded criteria donor kidney.

ABSTRACT

ObjectiveTo establish the frozen section method of Ferula ferulaeoides, and to study the histochemical localization of volatile oil and coumarins in different organs of F. ferulaeoides. MethodThe roots, stems, petioles and leaves of F. ferulaeoides were used as materials to investigate the concentration of sucrose protectant, liquid nitrogen flash-freezing time, embedding conditions, section thickness, freezing temperature and time and post-treatment methods, the most suitable section conditions were screened by comparing the integrity, microscopic effect, elongation and clarity of frozen sections. Sudan Ⅳ staining method and fluorescence microscopy were used to locate the volatile oil and coumarins of F. ferulaeoides. ResultThe optimal conditions for frozen sections of the roots, stems, petioles and leaves of F. ferulaeoides were as follows:10%, 15% and 20% gradient sucrose as the protectant for roots, 10%, 20% and 30% gradient sucrose as the protectant for stems and petioles, 20%, 25% and 30% gradient sucrose as the protectant for leaves, glue-water (2∶1) as the embedding agent, quick-freeze in liquid nitrogen for 20 s, warmed up at -25 ℃ for 30 min, sliced at -20 ℃ with the thickness of 25 μm, rinsed with the same concentration of sucrose solution (gradient sucrose solution selected the last concentration), and the slices placed on the ice pack for a period of time and stored at room temperature. Among them, the concentration of sucrose protectant was the most important factor. The results of histochemical localization showed that volatile oil and coumarins in four organs of F. ferulaeoides were mainly distributed in resin canal. ConclusionFrozen section of F. ferulaeoides is established for the first time with high rate of slicing and simplified steps, its volatile oil and coumarins are mainly accumulated in resin canal.

ABSTRACT

ObjectiveTo determine the association between air pollutants (PM2.5, PM10, SO2, NO2) and death from respiratory diseases in Wuhan. MethodsDaily air pollutants, meteorological data and mortality from respiratory disease between 2014 and 2019 were collected for a descriptive analysis. A time series semi-parametric generalized additive model (GAM) was used to determine the exposure-effect relationship between atmospheric pollutants and daily mortality from respiratory diseases,and the excess risk (ER) was used to quantify the effects of air pollutants on death from respiratory diseases. ResultsThere was significant effect of PM2.5, PM10, SO2 and NO2 on respiratory diseases mortality. In the period with strongest effect, the ER of death from respiratory diseases were 2.803%(95%CI:2.151%‒3.460%), 1.878%(95%CI:1.477%‒2.281%), 10.210%(95%CI:7.922%‒12.549%), 4.564%(95%CI:3.530%‒5.608%), along with an incremental 10 μg·m-3 of PM2.5,PM10,SO2 and NO2, respectively. Furthermore, females were more sensitive to PM2.5, SO2 and NO2, while males were more sensitive to PM10. Residents aged less than 65 years were more sensitive to PM2.5 and NO2, and those older than 65 years were more sensitive to PM10 and SO2. ConclusionAir pollutants (PM2.5, PM10, SO2, and NO2) in Wuhan are associated with the death from respiratory diseases. Therefore, at-risk groups should be considered for formulating local policies against air pollution.

ABSTRACT

Objective To analyze the trend of suicide mortality among the elderly aged 60 years and above in Wuhan from 2014 to 2019, to understand the disease burden of suicide deaths among the elderly adults in Wuhan, and to provide a basis for decision making to carry out suicide interventions in the elderly population. Methods The data on suicide deaths in the elderly adults of Wuhan residents whose death age was 60 years or older were collected from 2014 to 2019 using the Wuhan City's Cause of Death Monitoring Information System. Mortality, standardized mortality, years of life lost (YLL) due to early death and average years of life lost (AYLL) were calculated separately. Statistical analysis was performed using SPSS 26.0. The χ2 test was used to compare the suicide mortality rates among the elderly population by gender and region, and the annual percentage change (APC) was used for trend analysis. Results From 2014 to 2019, a total of 1010 suicide deaths were reported among elderly adults aged 60 years and older in Wuhan, with crude suicide mortality rates ranging from 7.60 to 10.77/100 000. The suicide mortality rate of elderly men was higher than that of elderly women. The suicide mortality rate of rural elderly adults was higher than that of urban elderly adults, and the suicide mortality rate of the rural elderly was decreasing. The overall suicide mortality rate of elderly people in Wuhan increased significantly with age, and the differences between the average suicide mortality rates of elderly males and elderly females in 2014-2019 were statistically significant among all age groups (P<0.01 or P<0.05). From 2014 to 2019, the YLL rate of suicide death among the elderly in Wuhan showed a trend of decreasing first and then increasing, and AYLL kept a slight fluctuation as a whole. The trends of both YLL rate and AYLL changes were not statistically significant. Conclusion The suicide mortality rate of elderly adults aged 60 years and above in Wuhan is high, especially in rural elderly men. The burden of disease caused by suicide deaths in the elderly is high, so it is necessary to take a variety of targeted measures to prevent and reduce the incidence of suicide among the elderly.

ABSTRACT

Objective:To investigate outcomes and safety of doxycycline-moxifloxacin sequential regimen in the treatment of Mycoplasma genitalium urethritis/cervicitis. Methods:From June 2019 to December 2020, patients with Mycoplasma genitalium urethritis/cervicitis confirmed by nucleic acid amplification testing were successively recruited at Department of Sexually Transmitted Diseases, Hospital of Dermatology, Chinese Academy of Medical Sciences, and received sequential therapy with oral doxycycline for 7 days followed by oral moxifloxacin for 7 days. Clinical and/or etiological assessment was conducted 2 to 3 weeks after the end of treatment. Fisher′s exact test was used to analyze factors influencing the treatment outcome. Results:Totally, 36 eligible subjects were enrolled, including 30 males and 6 females. Among them, 18 (50%) patients completed post-treatment etiological assessment, which showed that 12 achieved microbiological cure, and treatment failures occurred in 6; another 18 patients achieved clinical cure. The overall response rate to doxycycline-moxifloacin sequential therapy was 83.3% (30/36, 95% confidence interval[ CI]: 70.5%, 96.1%) . The treatment outcome showed no significant association with the patients′ age, gender, marital status, number of sexual partners in the past 1 month, history of sexually transmitted diseases, history of antibiotic use in the past 1 month, or co-infections (all P > 0.05) . Conclusion:The efficacy of doxycycline-moxifloacin sequential regimen is limited in the treatment of Mycoplasma genitalium infections in Nanjing area, and clinicians should be alerted to the possibility of treatment failure in clinical practice.

ABSTRACT

Objective:To explore the efficacy of sirolimus-based immunosuppressive protocol on tumor recurrence and tumor-free survival after liver transplantation(LT)in hepatocellular carcinoma (HCC)patients.Methods:From January 1, 2016 to December 31, 2018, a total of 114 HCC patients undergoing LT were recruited and divided into two groups of sirolimus(SRL)and tacrolimus. Univariate and multivariant analyses were performed for evaluating the risk factors of recurrence after LT. Tumor-free survival were compared using Cox logistic regression analysis.Results:Tumor recurrence and/or metastasis occurred in 45 patients. Univariate and multivariate regression analysis indicated that sirolimus was an independent protective factor for preventing tumor recurrence( P=0.005, HR=0.38, 95% CI 0.193~0.748). The median tumor-free survival time was 5(4~19)months in tacrolimus group and 23(13~31)months in sirolimus group. No inter-group statistical difference existed in incidence of infection or rejection complications( P>0.05). Conclusions:HCC patients benefit from sirolimus-based immunosuppressive protocol after LT. And sirolimus may reduce tumor recurrence rate and prolong tumor-free survival time.

ABSTRACT

Background and Objectives@#Galectin-3 promotes fibroblast-to-myofibroblast differentiation and facilitates injury repair. Previous studies have shown that exosomes derived from human umbilical cord mesenchymal stem cells (hucMSC-ex) promote the differentiation of myocardial fibroblasts into myofibroblasts under inflammatory environment. Whether hucMSC-ex derived Galectin-3 (hucMSC-ex-Galectin-3) plays an important role in fibroblast-to-myofibroblast differentiation is the focus of this study. @*Methods@#and Results: Galectin-3 was knocked-down by siRNA in hucMSCs, and then exosomes were extracted. Fibroblasts were treated with LPS, LPS+hucMSC-ex, LPS+negative control-siRNA-ex (NC-ex), or LPS+ Galectin-3-siRNA-ex (si-ex) in vitro. The coronary artery of the left anterior descending (LAD) branch was permanently ligated, followed by intramyocardial injection with phosphate buffered saline(PBS), hucMSC-ex, hucMSC-NC-ex, or hucMSC-si-ex in vivo. Western blot, RT-PCR, and immunohistochemistry were used to detect the expression of markers related to fibroblast-to-myofibroblast differentiation and inflammatory factors. Migration and contraction functions of fibroblasts were evaluated using Transwell migration and collagen contraction assays, respectively. β-catenin expression was detected by western blot and immunofluorescence. The results showed that hucMSC-ex increased the protein expression of myofibroblast markers, anti-inflammatory factors, and β-catenin. HucMSC-ex also reduced the migration and promoted the contractility of fibroblasts. However, hucMSC-si-ex did not show these activities. @*Conclusions@#HucMSC-ex-Galectin-3 promoted the differentiation of cardiac fibroblasts into myofibroblasts in an inflammatory environment, which was associated with increased β-catenin levels.

ABSTRACT

Thyroid carcinoma (TC) is one of the most prevalent endocrine malignancies worldwide. Patients with TC have high overall survival, but TC experienced the largest increase in incidence. Therefore, it is necessary to get further understanding of the mechanism involved in the development and progression of TC. The concept of the competing endogenous RNA (ceRNA) further illuminates the mechanism of tumorigenesis. Current studies indicate that psedugenic RNA, lncRNA, circRNA and mRNA, all of which may take part in the construction of ceRNETs as ceRNAs. These ceRNAs harbour the same miRNA response element (MRE) as mRNAs. Thus, ceRNAs can also competitively inhibit mRNA binding to the miRNAs, which results in affecting mRNA expression to exerts a pro-oncogenic or tumor-suppressive influence in tumor. Recently, a large number of studies have shown that ceRNA molecules play an important role in the malignant behavior of thyroid cancer. Therefore, it is necessary to summarize these studies. The purpose of this paper is to classify these ceRNA molecules in thyroid cancer and to elaborate the functions of these molecules in thyroid cancer.
