ABSTRACT

Objective:As the problem of global aging intensifies,postmenopausal osteoporosis (PMOP) has become a global health problem among females. At present,the commonly used biological agents have been proved not suitable for long-term use due to multiple adverse reactions. Several Meta-analyses have confirmed the good safety and effectiveness of kidney-tonifying method against PMOP,but its therapeutic mechanism remains unclear. The purpose of this Meta-analysis was to evaluate the effect of kidney-tonifying method on osteoclastogenesis inhibitory factor(OPG)/receptor activator of nuclear transcription factor (NF)-<italic>κ</italic>B (RANK)/receptor activator of NF-<italic>κ</italic>B ligand (RANKL) signaling pathway in PMOP animal model,so as to provide an experimental basis for the treatment of PMOP with kidney-tonifying method. Method:The related articles were retrieved from PubMed,Ovid Medline,Embase,China National Knowledge Infrastructure (CNKI),Chongqing Weipu Database for Chinese Technical Periodicals (VIP),and Wanfang Data Knowledge Service Platform with the retrieval time set from their inception to January 2020. The quality of each included article was evaluated using the SYRCLE's risk of bias tool. Then RevMan 5.3 was utilized for Meta-analysis according to the Cochrane systematic review methodology. Result:Thirty-two studies involving 619 rats were included. The quality score of these studies ranged from 3 to 5 points. The results of the Meta-analysis indicated obvious advantages of kidney-tonifying method in increasing bone mineral density (BMD)[standardized mean difference (SMD)=2.01,95% confidence interval(CI)=1.50-2.52,<italic>P</italic><0.000 01]),serum OPG level (SMD=3.33,95% CI=2.59-4.07,<italic>P</italic><0.000 01),and OPG mRNA expression (SMD=11.81,95% CI=7.49-16.13,<italic>P</italic><0.000 01),promoting OPG protein production (SMD=4.95,95% CI=3.09-6.81,<italic>P</italic><0.000 01),reducing serum RANKL(SMD=-4.88,95% CI=-6.01--3.75,<italic>P</italic><0.000 01) and RANK levels (SMD=-7.30,95% CI=-9.53--5.07,<italic>P</italic><0.000 01),and down-regulating RANKL (SMD=-6.22,95%CI=-8.95--3.49,<italic>P</italic><0.000 01) and RANK mRNA (SMD=-3.18,95% CI=-6.19--0.18,<italic>P</italic><0.05) expression and RANKL protein expression in bone tissue (SMD=-3.99,95% CI=-5.47--2.50,<italic>P</italic><0.000 01). Conclusion:The kidney-tonifying method has been proved to possess potential advantages in regulating the balance of OPG/RANK/RANKL signaling pathway in PMOP animal model. Nevertheless,more large-sample sized,properly designed,and high-quality animal experiments are still needed for further verification.

ABSTRACT

Objective@#To develop a machine learning (ML) pipeline based on radiomics to predict Coronavirus Disease 2019 (COVID-19) severity and the future deterioration to critical illness using CT and clinical variables. @*Materials and Methods@#Clinical data were collected from 981 patients from a multi-institutional international cohort with real-time polymerase chain reaction-confirmed COVID-19. Radiomics features were extracted from chest CT of the patients. The data of the cohort were randomly divided into training, validation, and test sets using a 7:1:2 ratio. A ML pipeline consisting of a model to predict severity and time-to-event model to predict progression to critical illness were trained on radiomics features and clinical variables. The receiver operating characteristic area under the curve (ROC-AUC), concordance index (C-index), and time-dependent ROC-AUC were calculated to determine model performance, which was compared with consensus CT severity scores obtained by visual interpretation by radiologists. @*Results@#Among 981 patients with confirmed COVID-19, 274 patients developed critical illness. Radiomics features and clinical variables resulted in the best performance for the prediction of disease severity with a highest test ROC-AUC of 0.76 compared with 0.70 (0.76 vs. 0.70, p = 0.023) for visual CT severity score and clinical variables. The progression prediction model achieved a test C-index of 0.868 when it was based on the combination of CT radiomics and clinical variables compared with 0.767 when based on CT radiomics features alone (p < 0.001), 0.847 when based on clinical variables alone (p = 0.110), and 0.860 when based on the combination of visual CT severity scores and clinical variables (p = 0.549). Furthermore, the model based on the combination of CT radiomics and clinical variables achieved time-dependent ROC-AUCs of 0.897, 0.933, and 0.927 for the prediction of progression risks at 3, 5 and 7 days, respectively. @*Conclusion@#CT radiomics features combined with clinical variables were predictive of COVID-19 severity and progression to critical illness with fairly high accuracy.

ABSTRACT

The novel coronavirus disease (COVID-19) pandemic is emerging as a global health threat and shows a higher risk for men than women. Thus far, the studies on andrological consequences of COVID-19 are limited. To ascertain the consequences of COVID-19 on sperm parameters after recovery, we recruited 41 reproductive-aged male patients who had recovered from COVID-19, and analyzed their semen parameters and serum sex hormones at a median time of 56 days after hospital discharge. For longitudinal analysis, a second sampling was obtained from 22 of the 41 patients after a median time interval of 29 days from first sampling. Compared with controls who had not suffered from COVID-19, the total sperm count, sperm concentration, and percentages of motile and progressively motile spermatozoa in the patients were significantly lower at first sampling, while sperm vitality and morphology were not affected. The total sperm count, sperm concentration, and number of motile spermatozoa per ejaculate were significantly increased and the percentage of morphologically abnormal sperm was reduced at the second sampling compared with those at first in the 22 patients examined. Though there were higher prolactin and lower progesterone levels in patients at first sampling than those in controls, no significant alterations were detected for any sex hormones examined over time following COVID-19 recovery in the 22 patients. Although it should be interpreted carefully, these findings indicate an adverse but potentially reversible consequence of COVID-19 on sperm quality.

ABSTRACT

The formulation of expert consensus on clinical application of Chinese patent medicines, in means of exploring the effective combination of experience and evidence to form a research method in line with the characteristics of Chinese patent medicines, is an important transitional stage for clinical researches on Chinese patent medicines. Pre-searching is a new step in the formulation of expert consensus on clinical application of Chinese patent medicines. Before steps of interview and investigation on clinical application, pre-searching is conducted to collect publications and literature on certain variety and similar Chinese patent medicines; the publications on related medical classics and formulas of this variety; the recommendation condition of this variety in clinical practice guidelines and expert consensus; and the medication regimens recommended in disease-specific guidelines. Pre-searching is designed to know about the advantages of certain variety of Chinese patent medicine as well as its potential problems recorded in the literature, which is helpful to find out the clinical positioning of Chinese patent medicines, develop reasonable clinical questions and provide ideas for formal literature searching. However, it is not the direct basis for developing clinical questions. Moreover, interviews and investigations are still needed to further clarify the clinical positioning of Chinese patent medicines and develop reasonable questions. This paper took expert consensus on clinical application of Yanshen Jianwei Capsules as an example to introduce the pre-searching process and methods used during formulation of expert consensus on clinical application of Chinese patent medicines, and to further discuss the role of pre-searching to facilitate the formulation of clinical questions on selection of participants, interventions, controls and outcomes.

ABSTRACT

We established a simple and sensitive GC-MS method for the determination of β-elemene in rat plasma and measured the pharmacokinetics of citronella grass extract in rats. Plasma samples were pretreated using liquid-liquid microextraction: 100 μL of plasma sample (containing naphthalene as the internal standard) was extracted with 50 μL of n-hexane. The determination was performed on DB-5ms column (30 m×0.25 mm, 0.25 μm). The initial column temperature was 60 ℃ and raised to 160 ℃ at a rate of 50 ℃·min-1, maintained for 3 min, and finally increased to 260 ℃ for 3 min. Helium was the carrier gas and the flow rate was 0.15 mL·min-1. The injection volume was 2 μL. EI and selected monitored ions pattern were used for ion scanning with m/z 128 (naphthalene) and m/z 93 (β-elemene). Citronella grass extract was administered to rats by intragastric administration and intravenous administration (containing β-elemene 55 mg·kg-1), and plasma was collected and prepared using an automated blood collection system. The linear range of β-elemene in plasma was 1.0-250 ng·mL-1 (r = 0.997), the limit of quantification was 1.0 ng·mL-1, the accuracy was -4.47% - -0.85%, the extraction recovery was between 56.02%-66.89%, and no obvious matrix effect (94.28%-108.63%) was found. The main pharmacokinetic parameters of β-elemene were AUC0-t (23.56 ± 4.40) ng·mL-1, tmax (1.67 ± 0.58) h, Cmax (7.36 ± 0.69) ng·mL-1, MRT0-t (2.76 ± 0.27) h, t1/2z (2.73 ± 1.36) h, Vz (7.39 ± 3.18) L·kg-1, CLz (1.95 ± 0.51) L·h-1·kg-1, and the absolute bioavailability was about 8.78%. The method is simple, accurate, and sensitive, and is suitable for the pharmacokinetic analysis of β-elemene in citronella grass extract in rats. All animal studies were implemented according to protocols, which were reviewed and approved by the Institutional Animal Care and Use Committee at Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences.

ABSTRACT

The Qinling-Daba Mountains area is the main producing areas of Gynostemma longipes for medicinal usage, and samples of wild whole plants in Pingli, Shaanxi Province and Qingchuan, Sichuan Province were collected. The ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UHPLC-Q-TOF-MS~E) was used to profile the chemical compositions and analyze the similarities and differences of G. longipes samples in these areas. Based on the accurate molecular weight and fragment information obtained from Q-TOF-MS~E, the structures of the main components were identified by combining with the mass spectra, chromatographic behaviors of reference standards and related literatures. The results showed that the components of wild G. longipes from different places among Qinling-Daba Mountains area were similar. Forty-five chemical components were identified in the whole plant of G. longipes from Pingli, Shaanxi Province, including 43 triterpenoid saponins and 2 flavonoids which contain all main peaks in its fingerprint. The main components are dammarane-type triterpenoid saponins, such asgypenoside ⅩLⅨ, gypenoside A and its malonylated product of glycosyl.

ABSTRACT

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

ABSTRACT

To understand the status of child health services by primary medical institutions in less developed areas in Sichuan province and provide evidence for the development of health policy for poverty alleviation. Annual child health records in the primary medical institutions selected through multistage stratified sampling in 21 prefectures in Sichuan were extracted during 2014-2018. Field survey and telephone interview were used to evaluate the performance of child health services provided and the child guardian's satisfaction degree. Sample descriptive statistics, pair sample -test, (2) test, trend (2) test, Pearson correlation analysis were used for statistical analysis. Except child system management rate, the other indicators reflecting the status of child health service in less developed areas in Sichuan were on rise (<0.05), and close to average level of whole province in 2018. Except child system management rate, the other indicators reflecting the status of child health management in less developed counties were lower than those in developed counties in Sichuan, most differences were significant (<0.05). Except child health management rate of traditional Chinese medicine, the other indicators reflecting the status of child health management in less developed counties were higher than those in poverty-stricken counties in Sichuan, most differences were not significant (≥0.05). Except child systematic management rate, the gap in indicators reflecting child health service status between less developed area and developed area was in reduction, some difference were significant (<0.05). The child guardian satisfaction degree was associated with true child health management rates (=0.947, =0.015), and child health management rate of traditional Chinese medicine (=0.996, <0.001). Some achievements have been made in child health services provided by primary medical institutions in less developed areas in Sichuan. To achieve the 2020 poverty alleviation goal, it is necessary to take measures to increase input and improve service level.

ABSTRACT

Objective:To comprehensively analyze the diagnosis and treatment programs and prevention and treatment programs on tratidional Chinese medicine (TCM) for coronavirus disease-2019 (COVID-19), and to provide suggestions for further development of TCM clinical guidelines. Method:Diagnosis and treatment programs on TCM for COVID-19 pneumonia, as well as prevention and treatment programs, clinical practice guidelines and expert consensus, were retrieved till Feb 19, 2020. The information about TCM syndrome differentiation, state of disease, and TCM treatments (decoction and Chinese patent medicines) were extracted and analyzed. Result:A total of 24 TCM programs/guidelines were included containing 23 diagnosis and treatment programs or prevention and treatment programs and one rapid advice guideline. Of the 23 TCM programs, 14 programs described the classification of TCM syndromes and the stages of disease,22 programs described the composition of the TCM decoction; seven programs described how to add and subtract the herbs according to different TCM syndromes,17 programs described the weight/volume of the herbs of TCM decoctions, three programs described the decoction method,six programs described the usage and dosage of TCM decoction, two programs clarified the course of treatment; none of the 23 programs indicated the source of evidence. The TCM treatment within the rapid advice guideline was in reference to the fourth edition of the COVID-19 pneumonia TCM diagnosis and treatment program issued by the National Health Commission. A total of 41 Chinese patent medicines were recommended in 23 programs, of which 12 Chinese patent medicines were off-label recommended. Conclusion:In most TCM programs, TCM decoction and Chinese patent medicines are recommended based on TCM syndrome differentiation in combination with the state of disease, and the dosage of the TCM decoctions are clearly described. Some Chinese patent medicines in the TCM programs are off-label recommended. Expert experience and opinions are valued when developing TCM programs/ guidelines. All of these provide reference for developing TCM programs/guidelines in future.

ABSTRACT

OBJECTIVE@#To investigate the value of optic disc retinal nerve fiber layer (RNFL) thickness in the diagnosis of diabetic peripheral neuropathy (DPN).@*METHODS@#Ninety patients with type 2 diabetes, including 60 patients without DPN (NDPN group) and 30 patients with DPN (DPN group), and 30 healthy participants (normal group) were enrolled. Optical coherence tomography (OCT) was used to measure the four quadrants and the overall average RNFL thickness of the optic disc. The receiver operator characteristic curve was drawn and the area under the curve (AUC) was calculated to evaluate the diagnostic value of RNFL thickness in the optic disc area for DPN.@*RESULTS@#The RNFL thickness of the DPN group was thinner than those of the normal and NDPN groups in the overall average ((101.07± 12.40) µm vs. (111.07±6.99) µm and (109.25±6.90) µm), superior quadrant ((123.00±19.04) µm vs. (138.93±14.16) µm and (134.47±14.34) µm), and inferior quadrant ((129.37±17.50) µm vs. (143.60±12.22) µm and (144.48±14.10) µm), and the differences were statistically significant. The diagnostic efficiencies of the overall average, superior quadrant, and inferior quadrant RNFL thicknesses, and a combined index of superior and inferior quadrant RNFL thicknesses were similar, and the AUCs were 0.739 (95% confidence interval (CI) 0.635-0.826), 0.683 (95% CI 0.576-0.778), 0.755 (95% CI 0.652-0.840), and 0.773 (95% CI 0.672-0.854), respectively. The diagnostic sensitivity of RNFL thickness in the superior quadrant reached 93.33%.@*CONCLUSIONS@#The thickness of the RNFL in the optic disc can be used as a diagnostic method for DPN.

ABSTRACT

BACKGROUND@#Minimal change nephropathy (MCD) is a common pathological type of nephrotic syndrome and is often associated with acute kidney injury (AKI). This study aimed to investigate the clinical characteristics and related factors of AKI in patients with MCD and nephrotic syndrome.@*METHODS@#Patients from Chinese People's Liberation Army General Hospital who were diagnosed with pathological renal MCD with clinical manifestations of nephrotic syndrome were included from January 1, 2013 to December 31, 2017. Patients diagnosed with membranous nephropathy (MN) by renal biopsy from January 1, 2013 to December 31, 2017 are included as a control population. We retrospectively analyzed the clinical and pathological characteristics of patients as well as the percentages and clinical characteristics of AKI in different age groups. We assessed the correlation of pathological characteristics with serum creatinine using multivariate linear regression analysis.@*RESULTS@#A total of 367 patients with MCD were included in the analysis, with a sex ratio of 1.46: 1 (male: female) and an age range of 6 to 77 years. Among all the patients, 109 developed AKI (29.7%), and of these patients, 85 were male (78.0%). In the 586 patients with MN, 27 (4.6%) patients developed AKI. The percentage of AKI in MCD patients was significantly higher than that in MN patients (χ2 = 41.063, P < 0.001). The percentage of AKI increased with age in the MCD patients. The percentage of AKI in patients aged 50 years or older was 52.9% (46/87), which was significantly higher than that [22.5% (63/280)] in patients under 50 years (χ2 = 6.347, P = 0.013). We observed statistically significant differences in age (43 [27, 59] years vs. 28 [20, 44] years, Z = 5.487, P < 0.001), male (78.0% vs. 51.4%, χ2 = 22.470, P < 0.001), serum albumin (19.9 ± 6.1 g/L vs. 21.5 ± 5.7 g/L, t = 2.376, P = 0.018), serum creatinine (129.5 [105.7, 171.1] μmol/L vs. 69.7 [57.7, 81.9] μmol/L, Z = 14.190, P < 0.001), serum urea (10.1 [6.2, 15.8] mmol/L vs. 4.7 [3.6, 6.4] mmol/L, Z = 10.545, P < 0.001), IgE (266.0 [86.7, 963.0] IU/ml vs. 142.0 [35.3, 516.5] IU/ml, Z = 2.742, P = 0.007), history of diabetes (6.4% vs. 1.2%, P = 0.009), and history of hypertension (23.9% vs. 5.1%, χ2 = 28.238, P < 0.001) between the AKI group and the non-AKI group. According to multivariate linear regression analysis, among the renal pathological features analyzed, renal tubular epithelial cell damage (β = 178.010, 95% CI: 147.888-208.132, P < 0.001) and renal interstitial edema (β = 28.833, 95% CI: 11.966-45.700, P = 0.001) correlated with serum creatinine values.@*CONCLUSIONS@#The percentage of AKI in MCD patients is significantly higher than that in MN patients. Patients over 50 years old are more likely to develop AKI. Renal tubular epithelial cell injury and renal interstitial edema may be the main pathological lesions that are associated with elevated serum creatinine in patients with MCD.

ABSTRACT

Temporomandibular joint disorder (TMD) is one of the common diseases in stomatology caused by a variety of factors, with a high incidence rate, especially among the young people with great pressure, and difficult to treat this disease. it was easy to relapse directly affects the physical and mental health and quality of life of the patients. Psychological factors had been proved to be one of the causes of temporomandibular joint disorder, and cognitive behavioral therapy was a form of psychological therapy that has been applied to a variety of problems, including mental illnesses such as depression, anxiety, and physical symptoms like pain. Cognitive behavioral therapy (CBT) was also used in stomatology department. This paper reviewed the origin, concept formation, theory formation, characteristics and application of CBT in TMJ disorders, in order to provide more evidence for clinical practice and reduce pain for patients.

ABSTRACT

Objective: This research aimed to explore the therapeutic effect and its mechanism of pirfenidone in liver cirrhosis induced by carbon tetrachloride in mice. Methods: Sixty male C57 BL/6 mice were randomly divided into the control group, model group and different doses of pirfenidone group, twelve rats in each group. Mice were intraperitoneally injected with 20% CCl4 soybean oil solution ( 5 ml/kg), twice a week for 7 weeks. And these mice were free to drink 20% ethanol solution in the third week after building the model. The low, medium and high dose groups were respectively given 50, 100 and 200 mg/kg of pirfenidone solution according to the body weights, while the model group and control group were given equal volume of blank solvent after building the model, once a day for 2 weeks. The serum level of ALT and AST, liver index, spleen index, the gene or protein expression level of TGF-β1 and Smad3 were analyzed before and after the treatment of pirfenidone. Results: The serum level of ALT, AST increased significantly in the model group ( P<0. 05), while decreased significantly in different doses of pirfenidone group ( P<0. 05). The liver and spleen index in the model group was significantly higher than that in the control group ( P<0. 05). However, after treating with pirfenidone, the liver and spleen index were significantly lower than that in the model group ( P<0. 05). The number of TGF-β1 positive cells in the model group was significantly more than that in the control group, but it was significantly decreased in the pirfenidone group. The gene expression level of Smad3 in the model group was significantly higher than that in the control group ( P<0. 05). The gene expression level of TGF-β1 and Smad3 in different doses of pirfenidone group were significantly lower than that in the model group ( P< 0. 05). Meanwhile, the protein level of TGF-β1 and Smad3 were significantly increased in the model group, while decreased in the pirfenidone group. Conclusion: Pirfenidone relieves liver cirrhosis caused by carbon tetrachloride in mice by inhibiting the TGF-β1/Smad3 signaling pathway.
