Conclusions:The medical laboratory talent training program based on the talent training principal of local colleges and universities combined with students' interests and industry needs can help improve the quality of talent training and broaden the employment path of graduates.

Gecacitinib hydrochloride tablets (gecacitinib for short, and formerly known as "jaktinib hydrochloride tablets") is a novel JAK and ACVR1 inhibitor, which not only blocks the JAK-STAT signaling pathway by inhibiting the activities of JAK1, JAK2, JAK3, and TYK2, thereby alleviating inflammation and splenomegaly symptoms, but also reduces hepcidin transcription by inhibiting ACVR1 activity, thereby improving iron metabolism imbalance and anemia. Data from phases Ⅱ and Ⅲ clinical trials suggest that gecacitinib can both alleviate splenomegaly and reduce constitutional symptoms in patients with myelofibrosis (MF) who are na?ve to JAK inhibitors or have been exposed to ruxolitinib, as well as improve anemia in patients with MF. This article describes the mechanisms of action, pharmacokinetic characteristics, clinical efficacy, and treatment-related adverse effects of gecacitinib in the treatment of MF, providing references for the rational application of this drug in MF.

Objective:To observe the effect of scleral buckling surgery (SB) in the treatment of rhegmatogenous retinal detachment (RRD) with subretinal hyperplasia (SRP).Methods:A retrospective case study. From January 2016 to December 2018, 31 patients with old RRD with SRP who were treated with SB in Department of Ophthalmology, Central Theater Command General Hospital were included in the study. There were 18 males with 20 eyes and 13 females with 15 eyes. Age was (26.5±8.7) years. The course of disease was (12.6±10.3) months. The best corrected visual acuity (BCVA) test was performed using the international standard visual acuity chart, which was converted to logarithm of the minimum angle of resolution (logMAR) visual acuity at the time of recording. Retinal detachment ranges ≤2, >2-<3, ≥3 quadrants were 10 (28.6%, 10/35), 20 (57.1%, 20/35), and 5 (14.3%, 5/35) eyes, respectively. All affected eyes were treated with SB. Among them, 22 eyes (63.0%, 22/35) underwent local Scleral buckling, 11 eyes (31.4%, 11/35) underwent combined encircling buckle, and 2 eyes (5.7%, 2/35) underwent encircling buckle alone. Subretinal fluid drainage was performed in 33 eyes (94.3%, 33/35). The mean follow-up time was 18.2 months. Relevant examinations were performed with the same equipment and methods before operation to observe BCVA and retinal reattachment. Paired sample t test was used to compare logMAR BCVA before and after operation. Results:At the last follow-up, retinal reattachment occurred in 32 eyes (91.4%, 32/35) of 35 eyes. The retina did not reset in 3 eyes (8.6%, 3/35). logMAR BCVA of affected eye was 0.67±0.29 (finger counting-1.0). The difference of logMAR BCVA before and after operation was statistically significant ( t=5.133, P=0.036). In 35 eyes, visual acuity improved, stabilized and decreased in 19 (54.3%, 19/35), 13 (37.1%, 13/35) and 3 (8.6%, 3/35) eyes, respectively. Ten months after surgery, the silicone tape was exposed and infected 1 eye. After the silicone tape was removed, the infection subsided and the retina was in place. There were no intraocular hemorrhage, vitreoretinal impaction, endophthalmitis and other complications during and after operation. Conclusion:SB treatment of RRD with SRP can achieve good retinal reposition and improve visual acuity to some extent.

With the rapid changes in people's lifestyles, natural and social environments in recent years, the prevalence of chronic and non-communicable diseases in China and its related risk factors have also had tremendous changes. The epidemiological characteristics of chronic and non-communicable diseases and their risk factors vary throughout the country, and the impact of unique climate, diet and lifestyle in southern China on the incidence and prevalence of chronic and non-communicable chronic diseases remains to be elucidated. Therefore, large-scale cohort study is urgently needed to provide evidence for the etiological research and management of chronic and non-communicable chronic diseases in different areas, and for the national management strategy for major chronic and non-communicable diseases. The prospective cohort study of chronic and non-communicable diseases in general population in southern China was established in December 2017. The study recruited permanent residents aged 35-74 years from both urban and rural areas in Guangdong, Hainan, Fujian Provinces and Guangxi Zhuang Autonomous Region. A big data platform of precision medicine which integrates health information with biological samples for long-term follow up has been established. A baseline database of 116 520 people aged (54.9±12.5) years, including 71 077 women (61.0%), has been established. Collecting questionnaire survey data, physical examination data, and biological samples. This paper briefly introduces the concept, design and progress of the prospective cohort study of chronic and non-communicable diseases in general population in southern China.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

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.

Abstract Bisphenols (BPs), which are mainly used in the production of polycarbonates and epoxy resins, are common endocrine disruptors (EDCs) in natural environments. Human mainly exposes to BPs via ingestion and skin. Previous studies have deteted BPs in human urine, serum, and milk samples, and children and pregnant women have a high level of exposure to to BPs. Based on international and national publications pertaining to BPs since 2009, this review describes the exposure to BPs in human urine, serum, and milk and summarizes neuroendocrine dysfunctions, oxidative stress injury and epigenetics changes caused by BPs, so as to provide insights into reducing the exposure to and health risk of BPs.

ObjectiveTo explore the association between dietary retinol intake and prognosis of patients with esophageal squamous cell carcinoma. MethodsThe study enrolled 388 cases with primary esophageal squamous cell carcinoma that was pathologically diagnosed in the first affiliated hospital of Fujian medical university and the cancer hospital of Fujian medical university from July 2014 to August 2019. Chi-square test was used to determine the relationship between retinol and patients' characteristics. Kruskal-Wallis rank sum test was used to analyze the relationship between retinol and multiple nutrients. Cox proportional hazards regression model was used to explore the association between dietary retinol and esophageal squamous cell carcinoma. ResultsPatients with esophageal squamous cell carcinoma did not significantly differ in gender， age， TNM stage， tumor length or nutrient intake by different retinol intakes （P>0.05）. Multivariate Cox regression analysis showed that the high retinol intake group had a better prognosis （overal survial：HR=0.279，95%CI：0.150‒0.520，P<0.001；disease-free survival：HR=0.306，95%CI：0.181‒0.516，P<0.001）. ConclusionHigh dietary retinol intake may improve the prognosis of patients with esophageal squamous cell carcinoma.

Early distinction of bipolar disorder (BD) from major depressive disorder (MDD) is difficult since no tools are available to estimate the risk of BD. In this study, we aimed to develop and validate a model of oxidative stress injury for predicting BD. Data were collected from 1252 BD and 1359 MDD patients, including 64 MDD patients identified as converting to BD from 2009 through 2018. 30 variables from a randomly-selected subsample of 1827 (70%) patients were used to develop the model, including age, sex, oxidative stress markers (uric acid, bilirubin, albumin, and prealbumin), sex hormones, cytokines, thyroid and liver function, and glycolipid metabolism. Univariate analyses and the Least Absolute Shrinkage and Selection Operator were applied for data dimension reduction and variable selection. Multivariable logistic regression was used to construct a model for predicting bipolar disorder by oxidative stress biomarkers (BIOS) on a nomogram. Internal validation was assessed in the remaining 784 patients (30%), and independent external validation was done with data from 3797 matched patients from five other hospitals in China. 10 predictors, mainly oxidative stress markers, were shown on the nomogram. The BIOS model showed good discrimination in the training sample, with an AUC of 75.1% (95% CI: 72.9%-77.3%), sensitivity of 0.66, and specificity of 0.73. The discrimination was good both in internal validation (AUC 72.1%, 68.6%-75.6%) and external validation (AUC 65.7%, 63.9%-67.5%). In this study, we developed a nomogram centered on oxidative stress injury, which could help in the individualized prediction of BD. For better real-world practice, a set of measurements, especially on oxidative stress markers, should be emphasized using big data in psychiatry.

Objective:To investigate the relationship between the expression of serum exsomal miRNA-155-5p (miR-155-5p) and prognosis in patients with esophageal squamous cell carcinoma (ESCC).Methods:A total of 336 samples from ESCC patients in Fujian Provincial Cancer Hospital from October 2014 to December 2015 were collected. The relative expression levels of serum exsomal miR-155-5p were detected by using real-time fluorescent quantitative polymerase chain reaction (qRT-PCR). Cut-off value of the expression levels of serum exsomal miR-155-5p was determined by using X-tile software. Based on the optimal cut-off value, patients were divided into miR-155-5p low expression group and miR-155-5p high expression group. The survival curve was drawn by using Kaplan-Meier method and Cox proportional hazards regression model was used to make survival analysis.Results:The cut-off value of serum exsomal miR-155-5p expression level was 2.340. According to the cut-off value, patients were divided into miR-155-5p low expression group (<2.340) of 51 cases and miR-155-5p high expression group (≥2.340) of 285 cases. There were no statistical differences in age ( χ2 = 0.020, P = 0.887), gender ( χ2 = 0.283, P = 0.595), tumor location ( χ2 = 0.063, P = 0.977), differentiation grade ( P = 0.474), clinical staging ( χ2 = 3.996, P = 0.136) and surgery treatment ( χ2 = 0.941, P = 0.332) of patients in both groups. ESCC patients in serum exsomal miR-155-5p high expression had a higher risk of death compared with patients in miR-155-5p low expression group ( HR = 1.763, 95% CI 1.049-2.961, P = 0.032). Conclusion:The high expression level of serum exsomal miR-155-5p is associated with poor prognosis in ESCC patients and it could be used as a prognostic new marker in ESCC patients.
