This study applied the grading of recommendations assessment, development and evaluation(GRADE) system and the integrated evidence chain-based effectiveness evaluation of traditional Chinese medicine(Eff-iEC) to evaluate the evidence for 12 commonly used Chinese patent medicines for the treatment of osteoporosis, which are frequently recommended in guidelines or expert consensuses. The results showed that Xianling Gubao Capsules/Tablets were rated as C(low-level evidence) according to the GRADE system, and as BA~+B~+(intermediate evidence) according to the Eff-iEC system. Jintiange Capsules were rated as C(low-level evidence) by the GRADE system, and as AA~+B(high-level evidence) by the Eff-iEC system. Gushukang Granules/Capsules were rated as C(low-level evidence) by GRADE system, and as BA~+B~+(intermediate evidence) by Eff-iEC system. Zuogui Pills were rated as C(low-level evidence) by GRADE system, and as AA~(++)B~+(high-level evidence) by Eff-iEC system. Qianggu Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AA~+B~+(high-level evidence) by Eff-iEC system. Zhuanggu Zhitong Capsules were rated as D(extremely low-level evidence) by GRADE system, and as BA~+B(intermediate evidence) by Eff-iEC system. Jingui Shenqi Pills were rated as D(extremely low-level evidence) by GRADE system, and as AA~+B(high-level evidence) by Eff-iEC system. Quanduzhong Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AD~+B~+(low-level evidence) by Eff-iEC system. Epimedium Total Flavones Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AAB~+(high-level evidence) by Eff-iEC system. Yougui Pills were rated as D(extremely low-level evidence) by GRADE system, and as AA~(++)B~(+ )(high-level evidence) by Eff-iEC system. Qigu Capsules were rated as D(extremely low-level evidence) by GRADE system, and as BB~+B(intermediate evidence) by Eff-iEC system. Liuwei Dihuang Pills were rated as C(low-level evidence) by GRADE system, and as AA~(++)B~+(high-level evidence) by Eff-iEC system. Overall, the Eff-iEC system provides a more comprehensive assessment of the effectiveness evidence for traditional Chinese medicine(TCM) than the GRADE system. However, it still has certain limitations that hinder its wider promotion and application. In terms of clinical evidence evaluation, both the Eff-iEC and GRADE systems reflect that the current clinical research quality on Chinese patent medicines for the treatment of osteoporosis is generally low. High-quality clinical trials are still needed in the future to further validate clinical efficacy.

OBJECTIVES: To investigate the epidemiological characteristics of human metapneumovirus (hMPV) and the risk factors for severe pneumonia in hospitalized children. METHODS: The epidemiological characteristics of hMPV in hospitalized children at Hebei Children's Hospital from January 2019 to December 2023 were retrospectively analyzed. The clinical data of hospitalized children with hMPV infection from April to December 2023 were included, and independent risk factors for severe pneumonia were identified through logistic regression. RESULTS: A total of 44 092 children were tested, with an hMPV positive rate of 7.30% (3 220/44 092). Children aged 3-6 years constituted the largest proportion (40.93%, 1 318/3 220) among hMPV-positive cases. The detection rate varied significantly by year (P<0.001), peaking in 2022 (12.35%, 978/7 919). The peak season of the epidemic was winter and spring from 2019 to 2021, but shifted to spring and summer from 2022 to 2023. The proportion of co-infection was 38.70% (1 246/3 220), primarily with rhinovirus (600/1 246, 48.15%), Mycoplasma pneumoniae (217/1 246, 17.42%), and respiratory syncytial virus (182/1 246, 14.61%). The main manifestations of hMPV pneumonia were cough, expectoration, and fever. Children with severe pneumonia were significantly younger (P<0.05). Wheezing, underlying diseases, co-infection, and younger age were identified as independent risk factors for severe pneumonia (P<0.05). CONCLUSIONS There are significant annual and seasonal differences in the epidemiological characteristics of hMPV in hospitalized children. Young age, underlying diseases, wheezing, and co-infection are independent risk factors for severe pneumonia.

Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. It has a high prevalence and poor prognosis. The application of antiarrhythmic drugs and even surgery cannot completely treat the disease, and there are many sequelae. AF can be classified into the category of "palpitation" in Chinese medicine according to its symptoms. Acupuncture has a significant effect on AF. The authors find that an important mechanism of acupuncture in AF treatment is to regulate the cardiac vagus nerve. Therefore, this article intends to review the distribution and function of vagus nerve in the heart, the application and the regulatroy effect for the treatment of AF.

OBJECTIVE: To investigate chronic hepatitis C virus (HCV) infection's effect on gestational liver function, pregnancy and delivery complications, and neonatal development. METHODS: A total of 157 HCV antibody-positive (anti-HCV[+]) and HCV RNA(+) patients (Group C) and 121 anti-HCV(+) and HCV RNA(-) patients (Group B) were included as study participants, while 142 anti-HCV(-) and HCV RNA(-) patients (Group A) were the control group. Data on biochemical indices during pregnancy, pregnancy complications, delivery-related information, and neonatal complications were also collected. RESULTS: Elevated alanine aminotransferase (ALT) rates in Group C during early, middle, and late pregnancy were 59.87%, 43.95%, and 42.04%, respectively-significantly higher than Groups B (26.45%, 15.70%, 10.74%) and A (23.94%, 19.01%, 6.34%) ( P < 0.05). Median ALT levels in Group C were significantly higher than in Groups A and B at all pregnancy stages ( P < 0.05). No significant differences were found in neonatal malformation rates across groups ( P > 0.05). However, neonatal jaundice incidence was significantly greater in Group C (75.16%) compared to Groups A (42.25%) and B (57.02%) ( χ ² = 33.552, P < 0.001). HCV RNA positivity during pregnancy was an independent risk factor for neonatal jaundice ( OR = 2.111, 95% CI 1.242-3.588, P = 0.006). CONCLUSIONS Chronic HCV infection can affect the liver function of pregnant women, but does not increase the pregnancy or delivery complication risks. HCV RNA(+) is an independent risk factor for neonatal jaundice.

Background: Genetic defects in the human thyroid-stimulating hormone (TSH) receptor (TSHR) gene can cause congenital hypothyroidism (CH). However, the biological functions and comprehensive genotype–phenotype relationships for most TSHR variants associated with CH remain unexplored. We aimed to identify TSHR variants in Chinese patients with CH, analyze the functions of the variants, and explore the relationships between TSHR genotypes and clinical phenotypes. Methods: In total, 367 patients with CH were recruited for TSHR variant screening using whole-exome sequencing. The effects of the variants were evaluated by in-silico programs such as SIFT and polyphen2. Furthermore, these variants were transfected into 293T cells to detect their Gs/cyclic AMP and Gq/11 signaling activity. Results: Among the 367 patients with CH, 17 TSHR variants, including three novel variants, were identified in 45 patients, and 18 patients carried biallelic TSHR variants. In vitro experiments showed that 10 variants were associated with Gs/cyclic AMP and Gq/11 signaling pathway impairment to varying degrees. Patients with TSHR biallelic variants had lower serum TSH levels and higher free triiodothyronine and thyroxine levels at diagnosis than those with DUOX2 biallelic variants. Conclusions We found a high frequency of TSHR variants in Chinese patients with CH (12.3%), and 4.9% of cases were caused by TSHR biallelic variants. Ten variants were identified as loss-of-function variants. The data suggest that the clinical phenotype of CH patients caused by TSHR biallelic variants is relatively mild. Our study expands the TSHR variant spectrum and provides further evidence for the elucidation of the genetic etiology of CH.

Objective:To investigate the influence of first pass effect (FPE) in prognoses of patients with acute intracranial large vessel occlusion in anterior circulation accepted mechanical thrombectomy with domestic stent retriever, and the influencing factors for FPE.Methods:A total of 223 patients with acute intracranial large vessel occlusion in anterior circulation accepted mechanical thrombectomy with domestic stent retriever were selected from 3 prospective, multicenter, open, randomized controlled clinical trials (REDIRECT trial, Tonbridge trial, CAPTURE trial). According to modified Rankin Scale (mRS) scores 90 d after thrombectomy, these patients were divided into good prognosis group (mRS scores≤2, n=131) and poor prognosis group (mRS scores>2, n=92); these patients were also divided into FPE group ( n=69) and non-FPE group ( n=154) according to whether FPE was achieved (complete recanalization with single stent retriever, modified Thrombolysis in Cerebral Infarction [mTICI] 3); differences in baseline data and surgical parameters between the 2 groups were compared; multivariate Logistic regression was used to analyze the independent influencing factors. Results:(1) Patients in the good prognosis group had significantly younger age, significantly lower National Institute of Health stroke scale (NIHSS) scores at admission, transient ischemic attack ratio, atrial fibrillation ratio and ratio of internal carotid artery as responsible occlusive vessel, statistically shorter time from onset to admission, time from onset to femoral artery puncture and time from femoral artery puncture to vascular recanalization compared with those in the poor prognosis group ( P<0.05); FPE proportion in the good prognosis group was significantly higher than that in the poor prognosis group ( P<0.05). Multivariate Logistic regression analysis showed that middle cerebral artery occlusion ( OR=0.459, 95% CI: 0.247-0.854, P=0.014), and FPE ( OR=2.485, 95% CI: 1.282-4.816, P=0.007), NIHSS score at admission ( OR=0.894, 95% CI: 0.837-0.955, P=0.001), time from femoral artery puncture to vascular recanalization ( OR=0.993, 95% CI: 0.987-0.999, P<0.001) were independent influencing factors for good prognosis. (2) The FPE group had significantly shorter time from femoral artery puncture to stent thrombectomy and higher proportion of balloon guided catheter (BGC) than the non-FPE group ( P<0.05). Multivariate Logistic regression analysis showed that BGC application was an independent influencing factor for FPE ( OR=3.185, 95% CI: 1.494-6.791, P=0.003). Conclusion:FPE can improve prognosis of patients with acute intracranial large vessel occlusion in anterior circulation accepted mechanical thrombectomy with domestic stent retriever, and BGC application helps FPE.

Objective To evaluate the accuracy,sensitivity,specificity and economy of HLA-B*5801 gene polymorphisms detection in predicting allopurinol-related severe drug eruption before receiving allopurinol treatment using rapid health technology assessment(rHTA),to provide clinicians and policymakers with an efficient and convenient evidence-based basis.Methods PubMed,Cochrane Library,Web of Science,Embase,WanFang Data,CNKI databases and the official website of health technology assessment(HTA)agency were electronically searched to collect HTA reports,systematic reviews/Meta-analyses and pharmacoeconomic literature on the HLA-B*5801 gene polymorphisms detection from inception to December 31,2023.Two reviewers independently screened studies,extracted data,assessed the included studies'quality,and analyzed and summarised the results.Results A total of 16 literature were included,of which 5 systematic reviews/Meta-analyses and 11 pharmacoeconomic studies.The results showed that the HLA-B*5801 gene mutation rate was significantly higher in patients presenting with severe drug eruption than in the allopurinol-tolerant group(P＜0.05).Two studies reported the sensitivity and specificity of the HLA-B*5801 gene polymorphisms assay for predicting severe drug eruption,the sensitivity of 0.78,0.93,and specificity of 0.96,0.89,respectively.The economic study showed that HLA-B*5801 gene polymorphisms detection before allopurinol treatment was cost-effective in Chinese Han,Korean,Thai populations,but not in British,American(Caucasian or Hispanic),Singaporean and Malaysian populations.Conclusion HLA-B*5801 gene polymorphisms detection before allopurinol treatment and guiding drug use according to the screening results in Chinese Han population can reduce the risk of severe drug eruption and treatment costs.

Objective To explore the efficacy and safety of low-dose tirofiban in stent-assisted coil embolization(SAC)for ruptured intracranial aneurysms.Methods From April 2011 to September 2020,335 patients of ruptured intracranial aneurysms with subarachnoid hemorrhage(SAH)admitted in the First People's Hospital of Changzhou were retrospectively analyzed.All cases underwent stent-assisted coil embolization within 24-48 h and antiplatelet medications.The patients were divided into dual antibody group(89 cases)and tirofiban group(246 cases).Baseline and clinical data of all patients were collected for comparison between groups,including age,sex,hypertension,diabetes mellitus,Hunt-Hess grade at admission,modified Fisher scale score at admission,aneurysm diameter(＞5 mm,≤5 mm),aneurysm location(anterior circulation,posterior circulation),postoperative acute hydrocephalus or intraventricular hemorrhage,postoperative complete embolization rate of ruptured aneurysm.All patients with ruptured intracranial aneurysm with SAH were confirmed by emergency cerebral CT scan after admission.The Raymond grading criteria were used to evaluate the embolization effect after operation:grade Ⅰ refers to no development(complete embolization),grade Ⅱ refers to only aneurysm neck development(incomplete embolization),and grade Ⅲ refers to aneurysm body development,in which Raymond grading Ⅰ orⅡ indicates effective embolization.Tirofiban group:4.2 μg/kg tirofiban was intravenously injected after the coil was placed in the aneurysm lumen and the stent was released,followed by maintenance dose 0.07 μg/(kg·min)for 6-8 h,and aspirin 100 mg and clopidogrel 75 mg were given as sequential dual antiplatelet therapy 2 hours before the tirofiban infusion was stopped.Dual antiplatelet group:a loading dose of aspirin 300 mg and clopidogrel 300 mg was given at least 2 hours before stent implantation,and then transferred to aspirin 100 mg and clopidogrel 75 mg given on the second day after operation.All patients received aspirin(100mg/d)for 6 months and clopidogrel(75 mg/d)for 3 months after operation.The efficacy indicators,safety indicators,adverse events and other complications of the two groups were collected and compared.The efficacy indicators were the incidence of thrombotic events during operation and within 72 hours after operation.The safety indicators were the incidence of intraoperative and early postoperative intracranial hemorrhage(within 48 hours after operation),the incidence of late postoperative intracranial hemorrhage(over 48 hours after operation),and the incidence of intracranial hemorrhage related to external ventricular drainage(symptomatic and asymptomatic).The adverse event was the occurrence of drug-related thrombocytopenia.Other complications were delayed ischemic events.The modified Rankin scale(mRS)score was used to evaluate the clinical prognosis of patients at 180 days after operation.mRS score ≤2 was defined as good prognosis,mRS score＞2 was defined as poor prognosis,of which 6 was defined as death.Results(1)There were no significant differences in baseline and clinical data between the tirofiban group and the dual antibody group(all P＞0.05).(2)There was no significant difference in the proportion of patients with good outcome(75.2％[185/246]vs.74.2％[66/89],P=0.845)and death(10.2％[25/246]vs.12.4％[11/89],P=0.566)at 180 days after operation between the tirofiban group and the dual antiplatelet group.(3)There was no significant difference in the incidence of intraoperative(0.8％[2/246]vs.4.5％[4/89],P=0.075)and postoperative thrombotic events(11.0％[27/246]vs.13.5％[12/89],P=0.527)between the tirofiban group and the dual antiplatelet group.(4)Results about safety comparison between this two antiplatelet regimens showed that the incidence of early postoperative intracranial hemorrhage were lower in the tirofiban group than that in the dual antiplatelet group(2.8％[7/246]vs.10.1％[9/89],P=0.014).There were no significant differences in the symptomatic external ventricular drainage related intracranial hemorrhage(0 vs.2/15,P=0.050),incidences of intraoperative intracranial hemorrhage(1.6％vs.3.4％,P=0.580),late postoperative intracranial hemorrhage(3.3％vs.4.5％,P=0.836),and drug-related thrombocytopenia(0.4％vs.1.1％,P=0.461)between the two groups.Conclusion Low-dose tirofiban infusion in SAC for ruptured aneurysms may prevent perioperative thromboembolic events without high risk of intracranial hemorrhage.

OBJECTIVE: To observe the clinical significance of translocator proteins (TSPO) gene in the treatment of FLT3-ITD/DNMT3A R882 double-mutated acute myeloid leukemia (AML). METHODS: Seventy-six patients with AML hospitalized in the Department of Hematology of the Affiliated People's Hospital of Ningbo University from June 2018 to June 2020 were selected, including 34 patients with FLT3-ITD mutation, 27 patients with DNMT3A R882 mutation, 15 patients with FLT3-ITD/DNMT3A R882 double mutation, as well as 19 patients with immune thrombocytopenia (ITP) hospitalized during the same period as control group. RNA was routinely extracted from 3 ml bone marrow retained during bone puncture, and TSPO gene expression was detected by transcriptome sequencing (using 2-deltadeltaCt calculation). RESULTS: The expression of TSPO gene in FLT3-ITD group and DNMT3A R882 group at first diagnosis was 2.02±1.04 and 1.85±0.76, respectively, which were both higher than 1.00±0.06 in control group, but the differences were not statistically significant (P=0.671, P=0.821). The expression of TSPO gene in the FLT3-ITD/DNMT3A R882 group was 3.98±1.07, wich was significantly higher than that in the FLT3-ITD group and DNMT3A R882 group, the differences were statistically significant (P=0.032, P=0.021). The expression of TSPO gene in patients who achieved complete response after chemotherapy in the FLT3-ITD/DNMT3A R882 group was 1.19±0.87, which was significantly lower than that at first diagnosis, and the difference was statistically significant (P=0.011). CONCLUSION TSPO gene may be used as an indicator of efficacy in FLT3-ITD /DNMT3A R882 double-mutated AML.
