Assessment of quality of life in patients with craniopharyngioma and identification of risk factors for compromised overall wellness

ABSTRACT Objective: Quality of Life (QoL) has been a multifactorial concerning issue in oncology. We aimed to inspect the pre-operative QoL among patients with craniopharyngioma and to explore the potential correlations between parameters of QoL and clinical indices. Subjects and methods: We enrolled a total of 109 patients with craniopharyngioma. We utilized Short Form 36 (SF-36), Symptom Check List-90, Generalized Anxiety Disorder Questionnaire scale (GAD7), Patient Health Questionnaire Depression (PHQ9) and Pittsburgh Sleep Quality Index to prospectively evaluated their QoL. Parameters of QoL along with clinical indices were compared among sub-groups divided according to Puget classification. Correlation analyses and regression analyses were performed to detect influential determinants to self-reported wellness. Results: Patients presented impaired QoL compared with general population ( p < 0.001), as assessed by SF-36. Correlation analyses indicated the detrimental influence resulting from central diabetes insipidus (CDI). Multivariate linear regression unveiled the adverse effect of CDI on Mental Component Summary (coefficient = −13.869, p = 0.007), GAD7 total score (coefficient = 2.072, p = 0.049) as well as PHQ9 total score (coefficient = 3.721, p = 0.001). Multivariate logistic regression verified CDI as a risk factor of developing depressive symptoms (OR = 6.160, p = 0.001). Conclusion: QoL of patients with craniopharyngioma was remarkably compromised before operation. CDI exerted detrimental influences on patients' QoL and it might serve as a marker for early identification of patients at risk of depression.

Evaluation of application effect of two-way referral service in the referral and treatment of coronary disease / 中华健康管理学杂志

Objective:To evaluate the effect of two-way referral service in referral and treatment of patients with coronary disease.Methods:A non-randomized controlled study was used, 80 patients with coronary disease who were referred to the First Affiliated Hospital of Xinjiang Medical University through the fast referral channel, also called green referral channel (GRC) of telemedicine service mode from January 2021 to January 2022 were selected as the GRC referral group. A propensity score was used to match 110 patients from the same period with coronary disease who were referred to this hospital through conventional medical channels and had similar basic conditions such as age, gender, region and medical insurance type as the conventional referral group. The differences in disease severity, referral time, hospitalization cost and other indicators were compared using t-test, χ2 test and nonparametric test between the two groups, and the satisfaction of the GRC referral group was investigated. Results:The proportion of patients with heart function grade Ⅲ (NYHA grading), heart failure, atrial fibrillation and interventional therapy in the GRC referral group was significantly higher than conventional referral group (all P<0.05). The total referral time and bed waiting time of patients in the GRC referral group were significantly shorter than conventional referral group [14.16 (9.62, 25.61) vs 34.39 (28.51, 49.68) h, 2.13 (0.83, 6.64) vs 24.58 (20.27, 27.68) h] ( Z=8.465, 9.172, all P<0.001). The hospitalization cost, surgical treatment cost and material cost in GRC referral group were significantly higher than conventional referral group [24 755 (11 559, 56 521) vs 14 700 (9 375, 29 534) CNY, 6 013 (2 096, 8 256) vs 2 562 (2 044, 6 154) CNY, 12 093 (1 267, 35 689) vs 1 329 (826, 16 125) CNY] ( Z=2.814, 2.917, 3.353, all P<0.05), and the diagnosis cost was significantly lower than conventional referral group [4 878 (3 628, 6 847) vs 5 719 (4 228, 7 639) CNY] ( Z=2.323, P<0.05). In the GRC referral group, the satisfaction rates with referral process, visit time and patient experience were all above 90%. Conclusion:Two-way referral service based on telemedicine has a good application effect in the referral and treatment of patients with coronary disease.

Zhishi Xiebai Guizhitang is a classical prescription for the treatment of chest impediment with the method of warming Yang. It is included in the Catalogue of Ancient Classical Prescriptions issued by the National Administration of Traditional Chinese Medicine （First Batch）， with the effect of activating Yang， dissipating mass， moving Qi and resolving phlegm. Its main symptoms include chest fullness and pain， or even chest pain radiating to the back， wheezing， coughing， shortness of breath， and Qi reversal from the hypochondrium. In modern traditional Chinese medicine， Zhishi Xiebai Guizhitang is clinically used in the treatment of cardiovascular system， digestive system， respiratory system and other diseases， among which coronary heart disease， unstable angina pectoris， myocardial infarction， sinus bradycardia and other cardiovascular diseases have particularly significant effects. This paper reviewed the pharmacological studies of Zhishi Xiebai Guizhitang in the past 10 years. The results showed that each single medicine and the whole prescription alleviated the above cardiovascular diseases to a certain extent， with the pharmacological effects of improving intravascular environment， myocardial ischemia， myocardial ischemia-reperfusion injury， and myocardial hypoxia， anti-inflammation， plaque stabilisation， etc.， and the pharmacological mechanism involved the regulation of relevant active substances in vivo as well as related signaling pathways and ion channels， mainly including thromboxane B2 （TXB2）， prostacyclin I2（PGI2） and phosphatidylinositol 3-kinases/protein kinase B/endothelial nitric oxide synthase （PI3K/Akt/eNOS） signaling pathways， and ATP-sensitive potassium channels. In addition， the relationship between the pharmacological effects of some single medicines and transient receptor potential ankyrin 1 （TRPA1） has been reported that TRPA1 is a key to understanding the mechanism of Zhishi Xiebai Guizhitang in treating cardiovascular diseases， which is worth of further study.

Effect of superfine powder and aqueous extract of Polygonati Rhizoma on rats with natural perimenopausal syndrome / 中国中药杂志

This study aims to examine the effect of superfine powder and aqueous extract of Polygonati Rhizomaon on natural perimenopausal syndrome in rats and explore the underlying mechanism. To be specific, a total of 60 female SD rats(14-15 months old) with estrous cycle disorder were screened by the vaginal smear and randomized into model control group, β-estradiol 3-benzoate group(0.1 mg·kg~(-1)), superfine powder of Polygonati Rhizoma group(0.25, 0.5 g·kg~(-1)) and aqueous extract of Polygonati Rhizoma group(0.25, 0.5 g·kg~(-1)), and another 10 female SD rats(14-15 months old) were selected as the youth control group. The administration lasted 6 weeks. Then the perimenopausal syndrome-related indexes such as body temperature, microcirculatory blood flow of face and ear, vertigo period, salivary secretion, grip force, and bone strength were determined and open field test was conducted. The immune system-related indexes such as the wet weight and index of thymus and spleen, percentage of T lymphocytes and subgroups in peripheral blood, and hematological indexes were measured. In addition, the ovary-related indexes such as estrous cycle, the wet weight and index of uterus and ovary, ovarian tissue morphology, and cell apoptosis were determined. Moreover, hypothalamus-pituitary-ovary axis(HPO)-related indexes such as serum sex hormone levels, cytochrome P450 family 11 subfamily A member 1(CYP11A1), cytochrome P450 family 19 subfamily A member 1(CYP19A1), and cytochrome P450 family 17 subfamily A member 1(P450 17A1) in ovarian tissue were measured. The results showed that the superfine powder and aqueous extract of Polygonati Rhizoma significantly decreased body temperature(anal, facial and dorsal temperature), microcirculatory blood flow in the ear, and vertigo period, increased salivary secretion, grip force, bone strength, total distance and total speed in the open field test, wet weight and index of thymus and spleen, lymphocyte ratio, CD3~+ level, and CD4~+/CD8~+ ratio, reduced neutrophil number and ratio, estrous cycle disorder ratio, and number of ovarian apoptotic cells, raised wet weight and index of uterus, wet weight of ovary, levels of inhibin B(INHB), estradiol(E_2), anti-müllerian hormone(AMH), and ovarian CYP11A1 and CYP19A1, decreased follicle-stimulating hormone(FSH) and luteinizing hormone(LH) content, and improved ovarian tissue morphology. It is suggested that the superfine powder and aqueous extract of Polygonati Rhizoma can improve the symptoms associated with natural perimenopausal syndrome in rats and enhance ovarian function and immune function. The mechanism is that they regulate HPO axis function by increasing estrogen synthesis.

Effect on Danggui Shaoyao Powder on mitophagy in rat model of Alzheimer's disease based on PINK1-Parkin pathway / 中国中药杂志

This study investigated the mechanism of Danggui Shaoyao Powder(DSP) against mitophagy in rat model of Alzheimer's disease(AD) induced by streptozotocin(STZ) based on PTEN induced putative kinase 1(PINK1)-Parkin signaling pathway. The AD rat model was established by injecting STZ into the lateral ventricle, and the rats were divided into normal group, model group, DSP low-dose group(12 g·kg~(-1)·d~(-1)), DSP medium-dose group(24 g·kg~(-1)·d~(-1)), and DSP high-dose group(36 g·kg~(-1)·d~(-1)). Morris water maze test was used to detect the learning and memory function of the rats, and transmission electron microscopy and immunofluorescence were employed to detect mitophagy. The protein expression levels of PINK1, Parkin, LC3BⅠ/LC3BⅡ, and p62 were assayed by Western blot. Compared with the normal group, the model group showed a significant decrease in the learning and memory function(P<0.01), reduced protein expression of PINK1 and Parkin(P<0.05), increased protein expression of LC3BⅠ/LC3BⅡ and p62(P<0.05), and decreased occurrence of mitophagy(P<0.01). Compared with the model group, the DSP medium-and high-dose groups notably improved the learning and memory ability of AD rats, which mainly manifested as shortened escape latency, leng-thened time in target quadrants and elevated number of crossing the platform(P<0.05 or P<0.01), remarkably activated mitophagy(P<0.05), up-regulated the protein expression of PINK1 and Parkin, and down-regulated the protein expression of LC3BⅠ/LC3BⅡ and p62(P<0.05 or P<0.01). These results demonstrated that DSP might promote mitophagy mediated by PINK1-Parkin pathway to remove damaged mitochondria and improve mitochondrial function, thereby exerting a neuroprotective effect.

Gut microbiota as a target for traditional Chinese medicine in the treatment of cardiovascular disease: potential mechanisms and therapy strategies / 药学学报

Cardiovascular disease (CVD) is a major contributor to patient deaths worldwide, and its pathogenesis is complex and mortality rates are increasing every year. Numerous researches have shown that the gut microbiota and its metabolites were closely associated with the development of CVD, and gut microbiota was expected to be a potential new target for the treatment of CVD. Traditional Chinese medicine (TCM), characterized by its multi-component, multi-target and integrity, can play a therapeutic role in CVD by regulating the gut microbiota, which has obvious advantages in stabilizing the disease, improving heart function and enhancing quality of life, and is an ideal intestinal microecological regulator. Therefore, this review will mainly discuss the intimate association of gut microbiota and its metabolites with CVD, and the therapeutic strategies of TCM targeting gut microbiota to improve CVD, including regulating the composition of gut microbiota, protecting the intestinal mucosal barrier, influencing the intestinal immune function and modulating the metabolites of gut microbiota, in order to provide a reference for the research of TCM targeting gut microbiota for CVD.

Prognostic value of a predictive model comprising preoperative inflammatory response and nutritional indexes in patients with gastric cancer / 中华胃肠外科杂志

Objective: To investigate the prognostic value of preoperative inflammatory and nutritional condition detection in the postoperative survival, and establish a prognostic model for predicting the survival of patients with gastric cancer. Methods: The clinicopathological data of 1123 patients with gastric cancer who had undergone radical gastrectomy in Tianjin Medical University Cancer Institute & Hospital from January 2005 to December 2014 were retrospectively analyzed. Patients with history of other malignancy, with history of gastrectomy, who had received preoperative treatment, who died during the initial hospital stay or first postoperative month, and missing clinical and pathological information were excluded. Cox univariate and multivariate analyses were used to identify independent clinicopathological factors associated with the survival of these gastric cancer patients. Cox univariate analysis was used to identify preoperative inflammatory and nutritional indexes related to the survival of patients with gastric cancer after radical gastrectomy. Moreover, the Cox proportional regression model for multivariate survival analysis (forward stepwise regression method based on maximum likelihood estimation) was used. The independent clinicopathological factors that affect survival were incorporated into the following three new prognostic models: (1) an inflammatory model: significant preoperative inflammatory indexes identified through clinical and univariate analysis; (2) a nutritional model: significant preoperative nutritional indexes identified through clinical and univariate analysis; and (3) combined inflammatory/nutritional model: significant preoperative inflammatory and nutritional indexes identified through clinical and univariate analysis. A model that comprised only pT and pN stages in tumor TNM staging was used as a control model. The integrated area under the receiver operating characteristic curve (iAUC) and C-index were used to evaluate the discrimination of the model. Model fitting was evaluated by Akaike information criterion analysis. Calibration curves were used to assess agreement between the predicted probabilities and actual probabilities at 3-year or 5-year overall survival (OS). Results: The study cohort comprised 1 123 patients with gastric cancer. The mean age was 58.9±11.6 years, and 783 were males. According to univariate analysis, age, surgical procedure, extent of lymph node dissection, tumor location, maximum tumor size, number of examined lymph nodes, pT stage, pN stage, and nerve invasion were associated with 5-year OS after radical gastrectomy for gastric cancer (all P<0.050). Multivariate analysis further identified age (HR: 1.18, 95%CI: 1.03-1.36, P=0.019), maximum tumor size (HR: 1.19, 95%CI: 1.03-1.38, P=0.022), number of examined lymph nodes (HR: 0.79, 95%CI: 0.68-0.92, P=0.003), pT stage (HR: 1.40, 95%CI: 1.26-1.55, P<0.001) and pN stage (HR: 1.28, 95%CI: 1.21-1.35, P<0.001) as independent prognostic factors for OS of gastric cancer patients. Additionally, according to univariate survival analysis, the preoperative inflammatory markers of neutrophil count, percentage of neutrophils, neutrophil/lymphocyte ratio, platelet/neutrophil ratio and preoperative nutritional indicators of serum albumin and body mass index were potential prognostic factors for gastric cancer (all P<0.05). On the basis of the above results, three models for prediction of prognosis were constructed. Variables included in the three models are as follows. (1) Inflammatory model: age, maximum tumor size, number of examined lymph nodes, pT stage, pN stage, percentage of neutrophils, and neutrophil-lymphocyte ratio; (2) nutritional model: age, maximum tumor size, number of examined lymph nodes, pT stage, pN stage, and serum albumin; and (3) combined inflammatory/nutritional model: age, maximum tumor size, number of examined lymph nodes, pT stage, pN stage, percentage of neutrophils, neutrophil-lymphocyte ratio, and serum albumin. We found that the predictive accuracy of the combined inflammatory/nutritional model, which incorporates both inflammatory indicators and nutrition indicators (iAUC: 0.676, 95% CI: 0.650-0.719, C-index: 0.698),was superior to that of the inflammation model (iAUC: 0.662, 95% CI: 0.673-0.706;C-index: 0.675), nutritional model (iAUC: 0.666, 95% CI: 0.642-0.698, C-index: 0.672), and TNM staging control model (iAUC: 0.676, 95% CI: 0.650-0.719, C-index: 0.658). Furthermore, the combined inflammatory/nutritional model had better fitting performance (AIC: 10 762) than the inflammatory model (AIC: 10 834), nutritional model (AIC: 10 810), and TNM staging control model (AIC: 10 974). Conclusions: Preoperative percentage of neutrophils, NLR, and BMI have predictive value for the prognosis of gastric cancer patients. The inflammatory / nutritional model can be used to predict the survival and prognosis of gastric cancer patients on an individualized basis.

Establishment and validation of a preoperative nomogram model for predicting the risk of hepatocellular carcinoma with microvascular invasion / 中华外科杂志

Objective: To establish and validate a nomogram model for predicting the risk of microvascular invasion(MVI) in hepatocellular carcinoma. Methods: The clinical data of 210 patients with hepatocellular carcinoma who underwent hepatectomy at Department of Hepatobiliary and Pancreatic Surgery,the Affiliated Hospital of Qingdao University from January 2013 to October 2021 were retrospectively analyzed. There were 169 males and 41 females, aged(M(IQR)) 57(12)years(range:30 to 80 years). The patients were divided into model group(the first 170 cases) and validation group(the last 40 cases) according to visit time. Based on the clinical data of the model group,rank-sum test and multivariate Logistic regression analysis were used to screen out the independent related factors of MVI. R software was used to establish a nomogram model to predict the preoperative MVI risk of hepatocellular carcinoma,and the validation group data were used for external validation. Results: Based on the modeling group data,the receiver operating characteristic curve was used to determine that cut-off value of DeRitis ratio,γ-glutamyltransferase(GGT) concentration,the inverse number of activated peripheral blood T cell ratio (-aPBTLR) and the maximum tumor diameter for predicting MVI, which was 0.95((area under curve, AUC)=0.634, 95%CI: 0.549 to 0.719), 38.2 U/L(AUC=0.604, 95%CI: 0.518 to 0.689),-6.05%(AUC=0.660, 95%CI: 0.578 to 0.742),4 cm(AUC=0.618, 95%CI: 0.533 to 0.703), respectively. Univariate and multivariate Logistic regression analysis showed that DeRitis≥0.95,GGT concentration ≥38.2 U/L,-aPBTLR>-6.05% and the maximum tumor diameter ≥4 cm were independent related factors for MVI in hepatocellular carcinoma patients(all P<0.05). The nomogram prediction model based on the above four factors established by R software has good prediction efficiency. The C-index was 0.758 and 0.751 in the model group and the validation group,respectively. Decision curve analysis and clinical impact curve showed that the nomogram model had good clinical benefits. Conclusions: DeRitis ratio,serum GGT concentration,-aPBTLR and the maximum tumor diameter are valuable factors for preoperative prediction of hepatocellular carcinoma with MVI. A relatively reliable nomogram prediction model could be established on them.

The Risk Factors and Outcomes for Radiological Abnormalities in Early Convalescence of COVID-19 Patients Caused by the SARS-CoV-2 Omicron Variant: A Retrospective, Multicenter Follow-up Study

Background@#The emergence of the severe acute respiratory syndrome coronavirus 2 omicron variant has been triggering the new wave of coronavirus disease 2019 (COVID-19) globally. However, the risk factors and outcomes for radiological abnormalities in the early convalescent stage (1 month after diagnosis) of omicron infected patients are still unknown. @*Methods@#Patients were retrospectively enrolled if they were admitted to the hospital due to COVID-19. The chest computed tomography (CT) images and clinical data obtained at baseline (at the time of the first CT image that showed abnormalities after diagnosis) and 1 month after diagnosis were longitudinally analyzed. Uni-/multi-variable logistic regression tests were performed to explore independent risk factors for radiological abnormalities at baseline and residual pulmonary abnormalities after 1 month. @*Results@#We assessed 316 COVID-19 patients, including 47% with radiological abnormalities at baseline and 23% with residual pulmonary abnormalities at 1-month follow-up. In a multivariate regression analysis, age ≥ 50 years, body mass index ≥ 23.87, days after vaccination ≥ 81 days, lymphocyte count ≤ 1.21 × 10 -9 /L, interleukin-6 (IL-6) ≥ 10.05 pg/mL and IgG ≤ 14.140 S/CO were independent risk factors for CT abnormalities at baseline. The age ≥ 47 years, presence of interlobular septal thickening and IL-6 ≥ 5.85 pg/mL were the independent risk factors for residual pulmonary abnormalities at 1-month follow-up. For residual abnormalities group, the patients with less consolidations and more parenchymal bands at baseline could progress on CT score after 1 month. There were no significant changes in the number of involved lung lobes and total CT score during the early convalescent stage. @*Conclusion@#The higher IL-6 level was a common independent risk factor for CT abnormalities at baseline and residual pulmonary abnormalities at 1-month follow-up. There were no obvious radiographic changes during the early convalescent stage in patients with residual pulmonary abnormalities.

Through the questionnaire surveys, the basic information of children and families and the activity information of children physical activity, sedentary behavior, and sleep were collected and statistically analyzed.@*Results@#The results showed that the median time of children daily leisure time physical activity (LTPA) was 20.0 (8.6, 38.6) min, children in suburb areas (18.6 min) and seventh grade (14.3 min) had shorter LTPA time( Z/H =5.12，119.11， P <0.01). The average daily sleep duration of children was (8.71 ± 0.76) h, the proportion of school age children with insufficient sleep reached 54.7%. With an increase in grades, the incidence of insufficient sleep increased significantly ( χ 2=407.13， P <0.01). The median daily sedentary time of children was 195.7(145.0, 255.7 ) min, and 84.5% of children engaged in more than two hours of sedentary behavior every day. Urban (202.9 min) and obese children (210.4 min) had longer sedentary behavior time, and with the increase in grade, the daily sedentary behavior time of children gradually increased ( Z/H =5.04，14.83，637.98， P <0.01).@*Conclusion@#Children and adolescents aged 6-14 years in Beijing have less LTPA time, too much sedentary time, and insufficient sleep duration. Grade is an important factor affecting physical activity, sedentary behavior, and sleep duration of children, and body shape may be related to their sedentary behavior and sleep time.It is suggested that targeted policies should be adopted for children of different grades to increase their physical activity and reduce their sedentary behavior to promote their healthy development.

Investigation and analysis of myopia and ocular biological parameters of primary and secondary school students in Urumqi / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the differences of myopia and ocular biological parameters of primary and middle school students in Urumqi.METHODS: A cross-sectional survey. A total of 2 495 primary and middle school students aged 7 to 18 from 4 schools in Urumqi were selected by judgemental sampling from September 2021 to November 2021 for relevant eye examination. The differences of ocular biological parameters and refractive status of students of different ages, genders and nationalities were compared, and the correlation between spherical equivalent(SE)and ocular biological parameters was analyzed.RESULTS: The detection rate of poor vision among the students was 80.36%, the detection rate of myopia was 55.91%, and the detection rate of astigmatism was 42.96%, among which the detection rate of low myopia was 63.80%, the detection rate of moderate myopia was 27.60%, and the detection rate of high myopia was 8.60%. There were significant differences in the detection rate of poor vision, myopia, astigmatism, SE and some ocular biological parameters among students of different ages and nationalities(all P<0.05). Among them, the detection rate of myopia, astigmatism and poor vision among Uygur and Kazakh ethnic groups was significantly lower than that of Han. The detection rate of poor vision and myopia among boys was lower than that among girls, while the detection rate of astigmatism was higher than that of girls. Spearman correlation analysis showed that axis length of eye, axial length to axial ratio, anterior chamber depth, and pupil diameter were negatively correlated with SE(rs=-0.664, -0.724, -0.320, -0.086, all P<0.001), and lens thickness was positively correlated with SE(rs=0.147, P<0.001).CONCLUSION: The prevalence of myopia among primary and secondary school students in Urumqi is high, and there are differences in the distribution of ocular biological parameters among children and adolescents of different ages and ethnicities.

Influencing factors of secondary primary cancer in patients with acute lymphoid leukemia / 公共卫生与预防医学

Objective To analyze the influencing factors of second primary cancer (SPC) in patients with acute lymphoblastic leukemia (ALL). Methods The Surveillance, Epidemiology and End Results database of the National Cancer Institute was used to extract data, and SEER*Stat program 8.4.0 was used to calculate the standardized incidence rate ratio (SIR) and absolute excess rate (AER). In addition, Cox regression models were used to estimate the hazard ratio (HR) of different age, race, sex, chemotherapy, and radiation and other factors for secondary tumors by R 4.2.1, and Kaplan-Meier method was used to plot the cumulative incidence. Results A total of 22 407 cases were included, and the person-years of follow-up were 142780.82. There was a total of 436 SPC cases, 32 of which developed multiple cancers. The median time of secondary cancers was 47.5 months. Patients with ALL had a higher risk of SPC than the general population (SIR=2.27; 95% , CI:2.07-2.50), and the most observed SPC was lymphatic and hematopoietic system, with an SIR of 6.96 (95% CI:5.94-8.11). The risk of SPC in ALL patients diagnosed in different time periods showed an upward trend, from 1.98 in 2000 to 2.38 in 2019. With the increase of age, the risk of SPC in ALL patients gradually decreased. Chemotherapy reduced the risk of SPC (HR=0.26; 95%CI: 0.19-0.36), while radiotherapy increased the risk of SPC by 59.60% (HR=1.57; 95% CI: 1.23-2.00). Conclusion In the future, chemotherapy is recommended for ALL patients to reduce radiation exposure during radiotherapy, and more attention should be paid to the health status of ALL patients within 1-5 years after their onset.
