ABSTRACT

Tripterygium wilfordii polyglycosides are one of the most commonly used Tripterygium wilfordii preparations, which have anti-inflammatory and immune-regulating effects. Their unique therapeutic effect on some autoimmune diseases and kidney diseases is almost irreplaceable by other similar drugs, but the possible reproductive damage is the bottleneck that hinders their clinical application. In clinical use, female patients often suffer from menstrual cycle disorders, decreased menstrual flow, even amenorrhea, infertility, and other symptoms, and the main toxic mechanism lies in damaging the reproductive and endocrine functions of the ovary and inhibiting the growth and development of follicles. Therefore, it is particularly necessary to understand the toxic and side effects of Tripterygium wilfordii polyglycosides on female reproduction and master the detoxification methods during clinical use. However, there is no clear solution to these problems. According to the theory of traditional Chinese medicine, "kidney governs reproduction", and the relationship between kidney Yin, kidney essence, and female ovum is close. Therefore, by considering that the damage to the reproductive system caused by Tripterygium wilfordii polyglycosides belongs to the category of kidney deficiency, Yin damage, and essence deficiency, the "strengthening kidney Yin" method is proposed. It points out that the reproductive toxicity damage of Tripterygium wilfordii polyglycosides on the female can be effectively alleviated by tonifying kidney and Yin essence in clinical use. The relevant research on traditional Chinese medicine, classical prescription, test prescription, and acupuncture is summarized to verify the necessity of the "strengthening kidney Yin" method, so as to provide a theoretical basis for the safe and rational clinical use of Tripterygium wilfordii.

ABSTRACT

BACKGROUND@#Links between alterations in gut microbiota composition and amyotrophic lateral sclerosis (ALS) have previously been reported. This study aimed to examine the microbiota in the nasal cavity of ALS.@*METHODS@#Sixty-six ALS patients and 40 healthy caregivers who live in close proximity with patients were enrolled. High throughput metagenomic sequencing of the 16S ribosomal deoxyribonucleic acid (rDNA) gene V3-V4 region of nasal microbiota was used to characterize the alpha and beta diversity and relative abundance of bacterial taxa, predict function, and conduct correlation analysis between specific taxa and clinical features.@*RESULTS@#The nasal microbiome of ALS patients showed lower alpha diversity than that of corresponding healthy family members. Genera Gaiella , Sphingomonas , Polaribacter _1, Lachnospiraceae _NK4A136_group, Klebsiella , and Alistipes were differentially enriched in ALS patients compared to controls. Nasal microbiota composition in ALS patients significantly differed from that in healthy subjects (unweighted UniFrac P = 0.001), while Linear discriminant analysis Effect Size (LEfSe) analysis indicated that Bacteroidetes and Firmicutes dominated healthy nasal communities at the phylum level, whereas Actinobacteria was the predominant phylum and Thermoleophilia was the predominant class in ALS patients. Genus Faecalibacterium and Alistipes were positively correlated with ALS functional rating scale revised (ALSFRS-R; rs = 0.349, P = 0.020 and rs = 0.393, P = 0.008), while Prevotella -9 and Bacteroides operational taxonomic units (OTUs) were positively associated with lung function (FVC) in ALS patients ( rs = 0.304, P = 0.045, and rs = 0.300, P = 0.048, respectively). Prevotella -1 was positively correlated with white blood cell counts (WBC, rs = 0.347, P = 0.021), neutrophil percentage (Neu%, rs = 0.428, P = 0.004), and neutrophil-to-lymphocyte ratio (NLR, rs = 0.411, P = 0.006), but negatively correlated with lymphocyte percentage (Lym%, rs = -0.408, P = 0.006). In contrast, Streptococcus was negatively associated with Neu% ( rs = -0.445, P = 0.003) and NLR ( rs = -0.436, P = 0.003), while positively associated with Lym% ( rs = 0.437, P = 0.003). No significant differences in nasal microbiota richness and evenness were detected among the severe and mild ALS patients.@*CONCLUSIONS@#ALS is accompanied by altered nasal microbial community composition and diversity. The findings presented here highlight the need to understand how dysbiosis of nasal microbiota may contribute to the development of ALS.

ABSTRACT

OBJECTIVE To evaluate the cost-effectiveness of pembrolizumab combined with chemotherapy versus placebo combined with chemotherapy in the first-line treatment of advanced or unresectable biliary tract carcinoma (BTC) from the perspective of China’s health system. METHODS A partitioned survival model was constructed based on the KEYNOTE-966 study data. The simulation period was 21 days, and the simulation time was the patient’s whole life. Using quality-adjusted life year (QALY) as the output indicator, the cost-utility analysis method was used to evaluate the cost-effectiveness of the two schemes mentioned above. Univariate and probabilistic sensitivity analyses were performed to verify the results of the basic analysis, and to explore the cost-effectiveness under the scenario of drug donation scheme. RESULTS The basic analysis showed that both the cost and effectiveness of the pembrolizumab group were higher than those of the placebo group, and the incremental cost-effectiveness ratio (ICER) was 3 909 359.78 yuan/QALY, which was higher than the willingness-to-pay (WTP) threshold of 3 times 2022 gross domestic product (GDP) per capita (257 094 yuan), indicating no cost-effectiveness. The results of univariate sensitivity analysis showed that the utility discount rate, the utility value of progression-free survival (PFS) status, the cost discount rate, and the cost of pembrolizumab had a great influence on ICER. Probabilistic sensitivity analysis verified the robustness of the results of basic analysis, and concluded that when the WTP threshold was greater than 1 500 000 yuan/QALY, the pembrolizumab group became cost-effective. The results of the scenario analysis showed that considering the drug donation scheme of pembrolizumab for low-income people, although its treatment cost was significantly reduced, it was still not cost-effective. CONCLUSIONS At the WTP threshold of 3 times China’s GDP per capita in 2022, pembrolizumab combined with chemotherapy is not cost-effective compared with placebo combined with chemotherapy for advanced or unresectable BTC.

ABSTRACT

The treatment of persistent/recurrent and metastatic thyroid cancer and medullary thyroid cancer has made significant progress through the use of molecule-targeted therapy. While this approach has shown promise in improving patient outcomes and clinical symptoms, it also carries potential risks. The primary focus and challenge of targeted therapy is to optimize benefits while managing risks within predetermined thresholds. This review examines current targeted treatment practices in thyroid cancer and investigates the correlation between the timing of targeted therapy initiation and the patient benefits, aiming to lay the groundwork for subsequent research.

ABSTRACT

Objective:To investigate the predictive values of 18F-FDG PET/CT image feature and metabolic parameters for the malignant potential of gastrointestinal stromal tumor (GIST). Methods:From March 2014 to June 2020, the 18F-FDG PET/CT imaging and surgical pathological data of 35 patients with GIST (27 males, 8 females; age 44-84 years) from Union Hospital, Tongji Medical College, Huazhong University of Science and Technology and Zhongnan Hospital of Wuhan University were analyzed retrospectively. Patients were divided into ring-shaped uptake group and other uptake patterns group according to 18F-FDG PET/CT image feature. Fisher′s exact test was used to analyze the differences of tumor necrosis and National Institutes of Health (NIH) risk classification (short for NIH classification) between different image feature groups. Mann-Whitney U test was used to analyze the differences of SUV max , metabolic parameters at different thresholds (2.5, 40%, 50%) of SUV max (metabolic tumor volume (MTV; MTV 2.5, MTV 40%, MTV 50%) and total lesion glycolysis (TLG; TLG 2.5, TLG 40%, TLG 50%)) between different clinicopathological features (lesion location, tumor diameter, mitotic count, Ki-67, necrosis, image feature, NIH classification) groups. Spearman rank correlation analysis was used to explore the correlation between clinicopathological features and metabolic parameters. ROC curve analysis was used to distinguish NIH classification of different metabolic parameters. Delong test was used to compared differences between different AUCs. Results:Of 35 GIST patients, 11(31.4%) were ring-shaped uptake and 24(68.6%) were other uptake patterns, and the differences of necrosis (7/11 vs 12.5%(3/24); P=0.004) and NIH classification (11/11 vs 25.0%(6/24); P<0.001) between the two groups were significant. There were significant differences of metabolic parameters between different groups of tumor diameter, mitotic count, necrosis, image feature, NIH classification ( z values: from -4.70 to -2.09, all P<0.05), while there were no significant differences of Ki-67 ( z values: from -0.83 to -0.71, all P>0.05). Metabolic parameters were correlated with mitotic count, tumor diameter, necrosis, image feature and NIH classification ( rs values: 0.36-0.81, all P<0.05), while was not correlated with Ki-67 ( rs values: 0.12-0.14, all P>0.05). The differences of AUCs between SUV max and MTV 2.5, TLG 2.5, TLG 40%, TLG 50%were significant (0.752, 0.856, 0.856, 0.882, 0.886; z values: 1.96-2.12, all P<0.05). Conclusions:The NIH classification of GIST with ring-shaped uptake on 18F-FDG PET/CT is higher and more prone to necrosis. The 18F-FDG PET/CT metabolic parameters based on different thresholds of SUV max have certain significance for the prediction of NIH classification of GIST, and may be superior to SUV max.

ABSTRACT

Objective:To compare the predictive value of parameters extracted from circular region-of-interest (ROI) with whole-liver histogram on gadoxetic acid disodium (Gd-EOB-DTPA)-enhanced T 1 map for postoperative liver failure in patients with liver focal lesions. Methods:The data of patients who underwent Gd-EOB-DTPA-enhanced MRI for focal liver lesions in Zhongshan Hospital, Fudan University from March 2016 to March 2018 were analyzed retrospectively. Forty patients were enrolled, including 30 males and 10 females, aged (56.6±12.1) years. According to the occurrence of postoperative liver failure, forty patients were divided into liver failure group ( n=14) and control group ( n=26). The parameters extracted from circular ROIs and whole liver histogram on T 1 map before Gd-EOB-DTPA enhancement and in hepatobiliary phase (HBP) were compared between the two groups. The receiver operating characteristic (ROC) curve was used to evaluate the value of these parameters in predicting postoperative liver failure. Results:The mean, standard deviation, median and 95% quantile of T 1 HBP in histogram parameters of liver failure group were significantly higher than those of control group (all P<0.05). The three parameters extracted from circular ROIs were not effective in predicting liver failure after hepatectomy (all P>0.05). Among all the liver histogram parameters, the area under the ROC curve of the 95% quantile before T 1 enhancement for predicting postoperative liver failure was 0.702 (95% CI: 0.523-0.881), the standard deviation of T 1 HBP was 0.739 (95% CI: 0.568-0.910), and the 95% quantile of T 1 HBP was 0.721 (95% CI: 0.540-0.903). The predictive efficacy were good (all P<0.05). Among them, the predictive performance of T 1 HBP standard deviation was the best, the area under the ROC curve was 0.739, the sensitivity was 85.7%, the specificity was 57.7%, and the best threshold was 54.8 ms. Conclusions:When Gd-EOB-DTPA enhanced T 1 mapping is used to predict postoperative liver failure in patients with focal liver lesions, the whole-liver histogram analysis is superior to the conventional circular ROI-based statistical method.

ABSTRACT

Objective:To investigate the correlation between the expression level of serum exosome miR-29C and postoperative cognitive dysfunction (POCD) in elderly patients undergoing surgery.Methods:A total of 119 elderly patients who underwent elective spinal surgery in the Second Hospital of Shanxi Medical University from January 2021 to January 2022 were selected and scored on the Montreal Cognitive Assessment (MoCA) Scale 1 day before surgery and 1, 7 and 21 days after surgery. The selected patients were divided into POCD group (51 cases) and non-POCD group (68 cases) according to whether the MoCA Scale score decreased ≥2 points 1 day before surgery and 1 day after surgery. S100-β, neuron-specific enolase (NSE) levels and serum exosome miR-29C expression levels were detected and analyzed in all patients 1 day before and 1 day after surgery. Pearson correlation analysis showed the correlation between MoCA Scale score and S100-β, NSE and miR-29C. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of S100-β, NSE and miR-29C for POCD occurrence in elderly patients undergoing surgery.Results:The score of MoCA Scale in POCD group were significantly decreased 1, 7 and 21 days after surgery compared with 1 day before surgery (all P<0.05), while the score of MoCA Scale in non-POCD group were significantly decreased only 1 day after surgery compared with 1 day before surgery ( P<0.05). The levels of S100-β and NSE and the expression level of serum exosome miR-29C in 2 groups were significantly increased 1 day after surgery compared with 1 day before surgery (all P<0.05). Moreover, the levels of S100-β and NSE and the expression level of serum exosome miR-29C in POCD group were significantly higher than those in non-POCD group 1 day after surgery (all P<0.05). There was a negative correlation between the MoCA Scale score and the expression level of serum exosome miR-29C 1 day after surgery in the POCD group ( P<0.05). ROC curve analysis showed that the expression levels of NSE, S100-β and exosome miR-29C 1 day after surgery predicted the risk of POCD in elderly surgical patients with area under the curve (AUC) of 0.891, 0.908 and 0.918, respectively. Conclusions:The occurrence of POCD in elderly patients with surgery is related to the increase of the expression level of serum exosome miR-29C, and the expression level of serum exosome miR-29C is negatively correlated with MoCA Scale score. Early monitoring of the miR-29C expression level can provide a basis for the occurrence and development of postoperative POCD in elderly patients, disease diagnosis and clinical intervention.

ABSTRACT

This study investigated the effect of multi-glycosides of Tripterygium wilfordii(GTW) on renal injury in diabetic kidney disease(DKD) rats through Nod-like receptor protein 3(NLRP3)/cysteine-aspartic acid protease-1(caspase-1)/gsdermin D(GSDMD) pyroptosis pathway and the mechanism. To be specific, a total of 40 male SD rats were randomized into the normal group(n=8) and modeling group(n=34). In the modeling group, a high-sugar and high-fat diet and one-time intraperitoneal injection of streptozotocin(STZ) were used to induce DKD in rats. After successful modeling, they were randomly classified into model group, valsartan(Diovan) group, and GTW group. Normal group and model group were given normal saline, and the valsartan group and GTW group received(ig) valsartan and GTW, respectively, for 6 weeks. Blood urea nitrogen(BUN), serum creatinine(Scr), alanine ami-notransferase(ALT), albumin(ALB), and 24 hours urinary total protein(24 h-UTP) were determined by biochemical tests. The pathological changes of renal tissue were observed based on hematoxylin and eosin(HE) staining. Serum levels of interleukin-1β(IL-1β) and interleukin-18(IL-18) were detected by enzyme-linked immunosorbent assay(ELISA). Western blot was used to detect the expression of pyroptosis pathway-related proteins in renal tissue, and RT-PCR to determine the expression of pyroptosis pathway-related genes in renal tissue. Compared with the normal group, the model group showed high levels of BUN, Scr, ALT, and 24 h-UTP and serum levels of IL-1β and IL-18(P<0.01), low level of ALB(P<0.01), severe pathological damage to kidney, and high protein and mRNA levels of NLRP3, caspase-1, and GSDMD in renal tissue(P<0.01). Compared with the model group, valsartan group and GTW group had low levels of BUN, Scr, ALT, and 24 h-UTP and serum levels of IL-1β and IL-18(P<0.01), high level of ALB(P<0.01), alleviation of the pathological damage to the kidney, and low protein and mRNA levels of NLRP3, caspase-1, and GSDMD in renal tissue(P<0.01 or P<0.05). GTW may inhibit pyroptosis by decreasing the expression of NLRP3/caspase-1/GSDMD in renal tissue, thereby relieving the inflammatory response of DKD rats and the pathological injury of kidney.

ABSTRACT

Objective: To development the prognostic nomogram for malignant pleural mesothelioma (MPM). Methods: Two hundred and ten patients pathologically confirmed as MPM were enrolled in this retrospective study from 2007 to 2020 in the People's Hospital of Chuxiong Yi Autonomous Prefecture, the First and Third Affiliated Hospital of Kunming Medical University, and divided into training (n=112) and test (n=98) sets according to the admission time. The observation factors included demography, symptoms, history, clinical score and stage, blood cell and biochemistry, tumor markers, pathology and treatment. The Cox proportional risk model was used to analyze the prognostic factors of 112 patients in the training set. According to the results of multivariate Cox regression analysis, the prognostic prediction nomogram was established. C-Index and calibration curve were used to evaluate the model's discrimination and consistency in raining and test sets, respectively. Patients were stratified according to the median risk score of nomogram in the training set. Log rank test was performed to compare the survival differences between the high and low risk groups in the two sets. Results: The median overall survival (OS) of 210 MPM patients was 384 days (IQR=472 days), and the 6-month, 1-year, 2-year, and 3-year survival rates were 75.7%, 52.6%, 19.7%, and 13.0%, respectively. Cox multivariate regression analysis showed that residence (HR=2.127, 95% CI: 1.154-3.920), serum albumin (HR=1.583, 95% CI: 1.017-2.464), clinical stage (stage Ⅳ: HR=3.073, 95% CI: 1.366-6.910) and the chemotherapy (HR=0.476, 95% CI: 0.292-0.777) were independent prognostic factors for MPM patients. The C-index of the nomogram established based on the results of Cox multivariate regression analysis in the training and test sets were 0.662 and 0.613, respectively. Calibration curves for both the training and test sets showed moderate consistency between the predicted and actual survival probabilities of MPM patients at 6 months, 1 year, and 2 years. The low-risk group had better outcomes than the high-risk group in both training (P=0.001) and test (P=0.003) sets. Conclusion: The survival prediction nomogram established based on routine clinical indicators of MPM patients provides a reliable tool for prognostic prediction and risk stratification.

ABSTRACT

ObjectiveDirected differentiation of human induced pluripotent stem cells (hiPSCs) into spinal cord γ-aminobutyric acid (GABA)-ergic progenitor cells were implanted into an decellularized optical nerve (DON) bioscaffold to construct a hiPSC-derived inhibitory neural network tissue with synaptic activities. This study aimed to provide a novel stem cell-based tissue engineering product for the study and the repair of central nervous system injury. MethodsThe combination of stepwise directional induction and tissue engineering technology was applied in this study. After hiPSCs were directionally induced into human neural progenitor cells (hNPCs) in vitro, they were seeded into a DON for three-dimensional culture, allowing further differentiation into inhibitory GABAergic neurons under the specific neuronal induction environment. Transmission electron microscopy and whole cell patch clamp technique were used to detect whether the hiPSCs differentiated neurons could form synapse-like structures and whether these neurons had spontaneous inhibitory postsynaptic currents, respectively, in order to validate that the hiPSC-derived neurons would form neural networks with synaptic transmission potentials from a structural and functional perspective. ResultsThe inhibitory neurons of GABAergic phenotype were successfully induced from hiPSCs in vitro, and maintained good viability after 28 days of culture. With the transmission electron microscopy, it was observed that many cell junctions were formed between hiPSC-derived neural cells in the three-dimensional materials, some of which presented a synapse- like structure, manifested as the slight thickness of cell membrane and a small number of vesicles within one side of the cell junctions, the typical structure of a presynatic component, and focal thickness of the membrane of the other side of the cell junctions, a typical structure of a postsynaptic component. According to whole-cell patch-clamp recording, the hiPSC-derived neurons had the capability to generate action potentials and spontaneous inhibitory postsynaptic currents were recorded in this biotissue. ConclusionsThe results of this study indicated that hiPSCs can be induced to differentiate into GABAergic progenitor cells in vitro and can successfully construct iPSC-derived inhibitory neural network tissue with synaptic transmission after implanted into a DON for three-dimensional culture. This study would provide a novel neural network tissue for future research and treatment of central nervous system injury by stem cell tissue engineering technology.

ABSTRACT

ObjectiveTo explore the underlying mechanism of Tripterygium wilfordii polyglycoside tablets (TWPT) in the prevention and treatment of kidney injury in diabetic nephropathy (DN) through the nuclear factor of activated T-cells 2(NFAT2)/cyclooxygenase-2(COX-2) pathway. MethodForty-two male SD rats of SPF grade were selected and randomly divided into a normal group (n=8) and an experimental group (n=34) after one week of adaptive feeding. The rats in the normal group were fed conventionally. The DN model was established in rats of the experimental group by intraperitoneal injection of streptozotocin (STZ) following one week of feeding on a high-fat and high-glucose diet. After the death and failure cases during modeling were eliminated, the remaining 24 model rats were randomly divided into model group, valsartan (8.33 mg·kg-1·d-1) group, and TWPT (5 mg·kg-1·d-1) group. Rats in normal group and model group were given equal amounts of normal saline by gavage. After six weeks, body weight was measured and urine samples were collected. Blood samples were collected from the abdominal aorta, and then the rats were sacrificed for sampling. Biochemical indicators, such as serum blood urea nitrogen (BUN), serum creatinine (SCr), alanine aminotransferase (ALT), blood lipid, blood glucose, and 24-hour urine total protein (24 h UTP), were determined. Hematoxylin-eosin (HE) staining and Masson staining were used to observe the pathology of the kidney. Enzyme-linked immunosorbent assay (ELISA) was used to detect NFAT2 and COX-2 expression levels in the serum. Western blot and Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR)were adopted to detect NFAT2, COX-2 protein and mRNA expression in kidney tissues, respectively. ResultCompared with the normal group, the model group showed elevated 24 h UTP, BUN, SCr, CHO, TG, and FBG, increased serum NFAT2 and COX-2 production and expression (P<0.01), and elevated protein and mRNA expression of NFAT2 and COX-2 in kidney tissues (P<0.01). In addition, the pathology of the kidney showed enlarged glomeruli, mild proliferation of mesangial cells, and widened mesangial stroma. Compared with the model group, the TWPT group showed decreased 24 h UTP, BUN, SCr, CHO, TG, and FBG (P<0.05,P<0.01), basically normal glomerular morphology, decreased expression of serum NFAT2 and COX-2 (P<0.01), and down-regulated protein and mRNA expression of NFAT2 and COX-2 in kidney tissues (P<0.01). ConclusionTWPT can alleviate 24 h UTP in DN model rats, protect renal function, and improve renal pathology, and its mechanism of action may be related to the down-regulation of NFAT2/COX-2 expression in the serum and kidney tissues.

ABSTRACT

Objective: To investigate the clinical characteristics of children with allergic diseases suffering from SARS-CoV-2 Omicron variant strains. Methods: This was a cross-sectional study. A total of 43 pediatric patients with allergic diseases infected by SARS-CoV-2 from April 25, 2022 to June 8, 2022 in Shanghai Jiao Tong University School of Medicine were selected as the allergic disease group, while 114 cases without underlying diseases and 16 cases with other underlying diseases were selected as control groups diagnosed at the same period. Clinical data including clinical features, laboratory tests, duration of hospitalization, and the time to negative turn of novel coronavirus nucleic acid were collected and analysed. Kruskal-Wallis H test, chi-square test or Fisher exact test were used for comparison among three groups. Results: Among the 43 patients with allergic diseases, 28 were males and 15 were females, with an age of 4.4 (2.1, 8.2) years on admission, including 32 mild cases and 11 common cases. The allergic disease group included 20 cases (46.5%) of atopic dermatitis and eczema, followed by 14 cases (32.6%) of rhinitis, 8 cases (18.6%) of food allergies, 7 cases (16.3%) of asthma, 4 cases (9.3%) of allergic conjunctivitis and 2 cases (4.7%) of drug allergy. Among the 114 cases without underlying diseases, 57 were males and 57 were females, with an age of 2.8 (1.2, 5.6) years on admission, including 93 mild cases and 21 common cases. Among the 16 cases with other underlying diseases, 9 were males and 7 were females, with an age of 3.0 (2.6, 10.8) years on admission, including 13 cases mild and 3 cases common cases. Children with allergic diseases had higher frequency of sore throat and vomiting than those without underlying diseases (10 cases (23.3%) vs.9 cases (7.9%), 14 cases (32.6%) vs. 11 cases (9.6%), χ²=6.93, 12.24, both P<0.05). The lymphocyte count of patients with allergic disease was lower than those without underlying disease (1.1 (0.7,1.7)×109 vs. 1.6 (1.1,2.7)×109/L, H=-28.00,P=0.005). There were no significant differences in age, gender, typing of SARS-CoV-2, the duration of hospitalization, cycle threshold values of SARS-CoV-2 and the time to negative turn of novel coronavirus nucleic acid among the three groups (all P>0.05). Conclusions: Children with allergic diseases may suffer from sore throat and vomiting more frequently when infected with SARS-CoV-2 Omicron variant. The combination of allergic diseases hardly influenced the disease course of SARS-CoV-2 in children.

ABSTRACT

OBJECTIVES@#To study the effect of improvement in antibiotic use strategy on the short-term clinical outcome of preterm infants with a gestational age of <35 weeks.@*METHODS@#The medical data were retrospectively collected from 865 preterm infants with a gestational age of <35 weeks who were admitted to the Neonatal Intensive Care Unit of Xiangya Hospital of Central South University from January 1, 2014 to December 31, 2016. The improved antibiotic use strategy was implemented since January 1, 2015. According to the time of implementation, the infants were divided into three groups: pre-adjustment (January 1, 2014 to December 31, 2014; n=303), post-adjustment Ⅰ (January 1, 2015 to December 31, 2015; n=293), and post-adjustment Ⅱ (January 1, 2016 to December 31, 2016; n=269). The medical data of the three groups were compared.@*RESULTS@#There were no significant differences among the three groups in gestational age, proportion of small-for-gestational-age infants, sex, and method of birth (P>0.05). Compared with the pre-adjustment group, the post-adjustment I and post-adjustment Ⅱ groups had a significant reduction in the rate of use of antibiotics and the duration of antibiotic use in the early postnatal period and during hospitalization (P<0.05), with a significant increase in the proportion of infants with a duration of antibiotic use of ≤3 days or 4-7 days and a significant reduction in the proportion of infants with a duration of antibiotic use of >7 days in the early postnatal period (P<0.05). Compared with the post-adjustment Ⅰ group, the post-adjustment Ⅱ group had a significant reduction in the duration of antibiotic use in the early postnatal period and during hospitalization (P<0.05), with a significant increase in the proportion of infants with a duration of antibiotic use of ≤3 days and a significant reduction in the proportion of infants with a duration of antibiotic use of 4-7 days or >7 days (P<0.05). Compared with the pre-adjustment group, the post-adjustment I and post-adjustment Ⅱ groups had significantly shorter duration of parenteral nutrition and length of hospital stay (P<0.05). There were gradual reductions in the incidence rates of grade ≥Ⅲ intraventricular hemorrhage (IVH) and late-onset sepsis (LOS) after the adjustment of antibiotic use strategy. The multivariate logistic regression analysis showed that the adjustment of antibiotic use strategy had no effect on short-term adverse clinical outcomes, and antibiotic use for >7 days significantly increased the risk of adverse clinical outcomes (P<0.05).@*CONCLUSIONS@#It is feasible to reduce unnecessary antibiotic use by the improvement in antibiotic use strategy in preterm infants with a gestational age of <35 weeks, which can also shorten the duration of parenteral nutrition and the length of hospital stay and reduce the incidence rates of grade ≥Ⅲ IVH and LOS.

ABSTRACT

Objective: To explore the correlation between club drug use and anal canal human papillomavirus (HPV) infection in HIV-negative and HIV-positive men who have sex with men (MSM) in Taizhou. Methods: A cross-sectional survey was conducted in Taizhou. HIV-negative MSM were recruited by convenient sampling in voluntary counseling and testing clinics of Taizhou prefectural CDC from August 2016 to October 2017, and HIV-positive MSM were recruited through the routine follow-up and management by Taizhou prefectural CDC from August 2016 to June 2019. A face-to-face questionnaire interview was conducted to collect the information about the socio-demographic characteristics, sexual orientation, sexual behavior, club drug use and other information of the participants. Anal canal swabs were collected for HPV genotyping. The correlation between club drug use and the prevalence of HPV infection were evaluated with χ2 test and logistic regression analysis. Results: A total of 69 HIV-negative and 345 HIV-infected MSM were included. The prevalence of any type of anal canal HPV infection in HIV-negative MSM (27.5%, 19/69) was lower than that in HIV-positive MSM (66.4%, 229/345) (χ2=36.114,P<0.001). The prevalence of self-reported club drug use in HIV-negative MSM was higher (17.4%, 12/69) than that in HIV-positive MSM (7.0%, 24/345) (χ2=7.886, P=0.005). For HIV-negative MSM, the prevalence of club drug use was higher in MSM who had homosexual group sex (P=0.036); the prevalence of HPV infection was 50.0% (6/12) in club drug users and 22.8% (13/57) in non-club drug users (χ2=3.674, P=0.055). For HIV-positive MSM, the prevalence of HPV infection was 70.8% (17/24) in club drug users and 66.0% (212/321) in non-club drug users (χ2=0.230, P=0.632). Multivariable logistic regression model showed that HPV infection in MSM was positively correlated with HIV infection (OR=5.42, 95%CI: 2.92-10.06), and the association between HPV infection and club drug use (OR=1.66, 95%CI: 0.75-3.71) was not significant. Conclusions: HIV infection was positively correlated with anal canal HPV infection in MSM in Taizhou. Club drug use was positively correlated with high-risk sexual behaviors, while its association with HPV infection needs further study.

ABSTRACT

Objective: To explore the correlation between alanine aminotransferase (ALT) trajectories and new-onset metabolic fatty liver disease (MAFLD) to provide a scientific basis for the prevention and treatment of MAFLD. Methods: The study cohort was composed of 3 553 subjects who met the inclusion criteria in the cohort study of the Henan physical examination population. According to the ALT levels of the subjects' physical examination from 2017-2019, three different ALT trajectory groups were determined by R LCTMtools, namely low-stable group, medium-stable group, and high-stable group. The incidence of MAFLD during physical examination in 2020 was followed up, the cumulative incidence rate in each group was calculated by product-limit method, and Cox proportional hazards regression model analyzed the correlation between different ALT trajectories and new-onset MAFLD. Results: The incidence rate of MAFLD parallelly increased with the increase of ALT locus, which was 6.93%, 15.42%, and 19.05%, respectively, and the difference was statistically significant (P<0.001). After adjusting for multiple confounding factors, such as gender, waist circumference, blood pressure, BMI, fasting blood sugar, and blood lipid by Cox proportional hazards regression model, the risks of MAFLD in ALT medium-stable and the high-stable group were still 1.422 times (95%CI:1.115-1.813) and 1.483 times (95%CI:1.040-2.114) of low-stable ALT group (P<0.05). Conclusions: The risk of MAFLD parallelly increases with the increase of ALT level in the normal long-term range. it is necessary to carry out the intervention for MAFLD with long-term average high value to avoid the progress of MAFLD disease to achieve the early prevention on MAFLD.

ABSTRACT

Ephedrae Herba is a commonly used medicine for dispersing wind and cold, which has a long medicinal history. By referring to the herbal literature, medical books and prescription books, this paper intends to carry out herbal textual research on the name, origin, medicinal part, producing area, harvesting and processing methods of Ephedrae Herba in famous classical formulas, in order to provide the basis for the development of relevant famous classical formulas. According to textual research, the main base of ancient Ephedrae Herba was Ephedra sinica. The medicinal part is the herbaceous stems of Ephedrae Herba. Before the Northern and Southern dynasties, the origin of the records was Jindi and Hedong, which is now Shanxi province. In the Northern and Southern dynasties and later generations, the producing area expanded, and now it is mainly distributed in Hebei, Shanxi, Shaanxi, Inner Mongolia, Gansu, Liaoning and other places, among which Inner Mongolia is the main producing area. The harvesting and processing methods in the past dynasties are to harvest the stems in autumn, dry them in the shade or air to 70%-80% dry, and then dry them in the sun. The processing methods in the past dynasties mainly include removing the knots, wine-fried, honey-fried, processing with vinegar and so on, at present, only honey-fried is still in use. Based on the research results, it is suggested that Ephedrae Herba in famous classical formulas should be selected the dry herbaceous stems of E. sinica. If the processing requirements are not indicated, it is suggested to use raw products of Ephedrae Herba.

ABSTRACT

In this paper, the name, classification, origin and other aspects of Schizonepetae Herba in the famous classical formulas were researched by referring to the related herbal literature, medical books and prescription books in the past dynasties. The results showed that Schizonepetae Herba first appeared in Shennong Bencaojing (《神农本草经》) as Jiasu, while Jingjie first appeared in Wupu Bencao (《吴普本草》), and the name of Jingjie was mainly used as the rectification of name in later generations. The name of Jiasu is mostly derived from its smell, and the name of Jingjie is mostly derived from its pronunciation. Schizonepeta tenuifolia has been highly praised in the past as a original material, and its genuine producing area is Jiangsu, Hebei and other places, medicinal part is whole herb with spike. In modern times, the quality of Schizonepetae Herba is best described as having thin stems, green spike, and aroma. In clinical application, the raw products of Schizonepetae Herba is mainly used, and the carbonisata is mainly used for hemostasis. Famous classical formulas of Huaihuasan and Danggui Yinzi are all made of Schizonepetae Spica, so it is recommended to use the dried panicle of S. tenuifolia. In Liangxue Dihuangtang, Schizonepetae Herba Carbonisata is used, therefore, it is suggested to adopt the processing method of Schizonepetae Herba Carbonisata in the 2020 edition of Chinese Pharmacopoeia.

ABSTRACT

ObjectiveTo evaluate the efficacy and safety of An'erning granules in the treatment of community-acquired pneumonia in children. MethodA randomized, double-blind, single-simulation, placebo-controlled trial was designed in this study. The children were randomly assigned into an observation group (An'erning granules combined with ceftriaxone sodium) and a control group (An'erning granules placebo combined with ceftriaxone sodium) according to the ratio of 2∶1. The disease cure rate was taken as the main indicator of efficacy, and the safety of An'erning granules was observed. ResultA total of 206 children (137 in the observation group and 69 in the control group) were included in this study. Before treatment, the age, sex, body height, body weight, diagnosis time of pneumonia, and symptom and sign scores had no significant differences between the two groups. After 8 days of continuous medication, the observation group[70.80%(97/137)] had higher cure rate than the control group[56.52%(39/69)](χ2=4.17,P<0.05) and total effective rate of chest X-ray [97.98%(97/99)] than the control group[86.27%(44/51)] (χ2=12.98,P<0.01). The observation group was superior to the control group in the alleviation of TCM syndrome under the condition of 0-3 g dose stratification on day 3 of medication (P<0.01). The recovery time, time to complete fever abatement, time to fever abatement and expectoration alleviation, rate of conversion to severe case, and reduction in the frequency of antibiotic use showed no significant differences between the two groups. In terms of safety, 13 and 7 adverse events occurred in the observation group and control group, respectively, which were relieved or disappeared after drug withdrawal or symptomatic treatment and showed no significant difference between the two groups. ConclusionIntravenous drip of ceftriaxone sodium combined with An'erning granules is effective in the treatment of community-acquired pneumonia in children. It can accelerate the absorption of pulmonary inflammation, alleviate the clinical symptoms in a short time for young children or the children with mild symptoms, and is safe in clinical application.
