The adulteration and counterfeiting of herbal ingredients in medicinal and food homology (MFH) have a serious impact on the quality of herbal materials, thereby endangering human health. Compared to pharmaceutical drugs, health products derived from traditional Chinese medicine (TCM) are more easily accessible and closely integrated into consumers' daily life. However, the authentication of the authenticity of TCM ingredients in MFH has not received sufficient attention. The lack of clear standards emphasizes the necessity of conducting systematic research in this area. This study utilized DNA barcoding technology, combining ITS2, psbA-trnH, matK as universal barcode sequences, and DX, HH, JYH as specific barcode sequences, to identify the authenticity of commercial medicinal and food homology scented herbal teas. The aim was to investigate the authenticity of scented herbal tea products circulating in the market. The research results revealed that among 180 scented herbal tea samples, DNA barcodes were successfully obtained from 164 samples, while the remaining samples either lacked the target components or suffered severe DNA degradation, resulting in failed amplification. Combined with morphological identification studies, it was found that out of the 180 samples, 141 were authentic, accounting for 78.33% of the total samples, while 31 samples showed adulteration and 8 samples lacked the target components, accounting for 21.67% of the total samples. Additionally, water testing revealed that 5 samples of Carthamus tinctorius herbal tea exhibited the phenomenon of weight adulteration. This study exposed the presence of adulteration and weight adulteration in scented herbal tea products, highlighting the need for regulatory authorities to expedite the establishment of quality standards in scented herbal tea industry. These findings provide valuable insights for the rapid development of the scented herbal tea industry.

Objective To explore the clinical efficacy of high hip center technique total hip arthroplasty(THA)for CroweⅡ and Ⅲ developmental dysplasia of hip(DDH)and severe hip osteoarthritis(HOA).Methods From January 2018 to Jan-uary 2020,74 patients with Crowe type Ⅱ and Ⅲ DDH and severe HOA were admitted,and 37 cases of anatomical hip center reconstruction were taken as control group,including 7 males and 30 females,aged from 42 to 65 years old with an average of(58.40±4.98)years old,body mass index(BMI)ranged from 18 to 29 kg·m-2 with an average of(23.02±2.21)kg·m-2.Thirty-seven routine high hip center technical reconstruction were performed as study group,including 5 males and 32 females,aged from 41 to 65 years old with an average of(57.31±5.42)years old,BMI ranged from 18 to 29 kg·m-2 with an average of(23.14±2.07)kg·m-2.The patients presented with hip pain,limited function and range of motion,and gait instability before surgery.All patients underwent THA,the control group underwent intraoperative anatomical hip center reconstruction,and the study group underwent intraoperative high hip joint reconstruction.The perioperative indicators of the two groups were com-pared.The hip joint function,balance function and gait of the patients were evaluated before surgery,3 months,6 months,and 12 months after surgery.The length difference of both lower limbs,horizontal distance of rotation center,vertical distance of ro-tation center and femoral eccentricity were measured before operation and 1 year after operation.The incidence of complica-tions in the two groups during the operation and postoperative follow-up was counted.Results The operation time of the study group was shorter than that of the control group,and the intraoperative blood loss was less than that of the control group(P＜0.05).After 12-months follow-up,1 was lost to followvup in study group and 2 were lost to follow-up in control group.The Har-ris scores and Berg balance scale(BBS),pace,stride frequency and single step length in the study group were higher than those in the control group at 3 months and 6 months after operation(P＜0.05);there was no statistically significant difference between the two groups in the indexes 12 months after operation(P＞0.05).The vertical distance of the center of rotation of the study group was greater than that of the control group 12 months after operation(P＜0.05),and there was no significant difference in the length difference of the lower limbs,the horizontal distance of the center of rotation,and the femoral eccentricity between two groups(P＞0.05).There were no complications in either group.Conclusion The long-term effects of TH A in patients with DDH and severe HO A were similar between the two central hip reconstruction methods,and the safety was good,and the high hip central reconstruction technique could shorten the operation time and reduce the amount of intraoperative blood loss.At the same time,it has certain advantages in early recovery of hip joint function,balance function and walking function of patients.

OBJECTIVE: To analyze the risk factors for refracture of adjacent vertebrae after percutaneous vertebroplasty (PVP) in super-old patients with osteoporotic vertebral compression fractures(OVCFs). METHODS: A retrospective analysis was performed on 40 patients(age≥90 years) with OVCFs who underwent PVP between June 2012 and June 2019. There were 7 males and 33 females, age from 90 to 101 years old with an average of (94.6±1.6) years. Patients were divided into two groups according to whether adjacent vertebral refracture occurred after PVP. Among them, 20 patients occurred refracture after PVP (refracture group) and 20 patients did not occur it(control group). The general information, radiological data and pelvic parameters of the two groups were collected. The items included age, gender, body mass index (BMI), fracture site and bone mineral density(BMD) T-value, fracture to operation time, compression degree of injured vertebra, recovery degree of anterior edge of injured vertebra, bone cement injection amount, bone cement leakage, pelvic index(PI), pelvic tilt angle (PT), sacral angle(SS), et al. Factors that may be related to refracture were included in the single-factor study, and multivariate Logistic regression analysis was performed on the risk factors with statistical significance in the single-factor analysis to further clarify the independent risk factors for refracture of adjacent vertebral bodies after PVP. RESULTS: There were no significant differences in age, gender, fracture site, fracture to operation time, compression degree of injured vertebra and recovery degree of anterior edge of injured vertebra between two groups (P>0.05). There were significant differences in BMI, BMD T-value, bone cement injection amount and bone cement leakage rate between two groups(P<0.05). The PI and PT values of the refracture group were higher than those of the control group(P<0.05). There was no significant difference in SS between two groups (P>0.05). Multivariate Logistic regression analysis showed that decreased BMD T-value, bone cement leakage, increased PT and PI values increased the risk of recurrence of adjacent vertebral fractures in OVCFs (P<0.05). CONCLUSION There are many risk factors for the recurrence of adjacent vertebral fractures in super-old patients with OVCFs. Patients with high PI and PT values may be one of the risk factors.

Objective:To explore the clinical efficacy of liver transplantation for Wilson's disease(WD).Methods:From January 1999 to November 2021, clinical data were retrospectively reviewed for 16 recipients with WD undergoing liver transplantation.There were 9 males and 7 females with an age range of 29.5(14~54)years.They were followed up by telephone, outpatient services and hospitalization.The starting point of follow-up was operation date.And recipient death was an endpoint.Postoperative survival, improvement of neuropsychiatric symptom, changes of corneal K-F ring, altered levels of liver function and serum copper-protein at Month 1 post-operation were observed.The follow-up deadline was November 24, 2021.Results:15 recipients underwent classical orthotopic liver transplantation and the other one recipient underwent living-related liver transplantation.No perioperative deaths occurred.All 16 recipients were followed up for 122(6~260)months.The 1-, 5-, and 10-year survival rates were 93.8%、85.2%and 75.8%, respectively.Among 10 recipients with corneal K-F ring positive with varying degrees after operation and was disappeared in 2 recipients at 7 and 11 months.Among 5 recipients with neuropsychiatric manifestation, 4 recipients showed ameliorative neuropsychic symptoms with varying degrees after operation and 1 recipient died.All the levels of liver function and serum copper-protien of all recipients recovered obviously in 1 month and the 1-, 5-, and 10-year post-operation.Conclusions:Classical orthotopic liver transplantation and living-related liver transplantation not only effectively improves copper metabolism of patient with WD and relieves their severe neurological manifestation, but also improves their life and prolongs survival, which is worthy of clinical promotion.

Solid tumors always exhibit local hypoxia, resulting in the high metastasis and inertness to chemotherapy. Reconstruction of hypoxic tumor microenvironment (TME) is considered a potential therapy compared to directly killing tumor cells. However, the insufficient oxygen delivery to deep tumor and the confronting "Warburg effect" compromise the efficacy of hypoxia alleviation. Herein, we construct a cascade enzyme-powered nanomotor (NM-si), which can simultaneously provide sufficient oxygen in deep tumor and inhibit the aerobic glycolysis to potentiate anti-metastasis in chemotherapy. Catalase (Cat) and glucose oxidase (GOx) are co-adsorbed on our previously reported CAuNCs@HA to form self-propelled nanomotor (NM), with hexokinase-2 (HK-2) siRNA further condensed (NM-si). The persistent production of oxygen bubbles from the cascade enzymatic reaction propels NM-si to move forward autonomously and in a controllable direction along H

Objective:To evaluate the efficacy and long-term effect of functional electrical stimulation (FES) on cerebral palsy. Methods:Literature retrieval was carried out in the electronic databases of PubMed, Embase, Web of Science, Cochrane Library, China Biology Medicine Disc (CBM), CNKI, Wanfang Database and VIP. The time limit was from the establishment of these databases to March 26th, 2020. According to the inclusion and exclusion criteria, randomized controlled trials about FES for children with cerebral palsy were included. At least two evaluators extracted the data independently and used Cochrane 5.1.0 bias risk assessment tool to evaluate the quality of included studies. The data was analyzed with Review Manager 5.3 software. Results:A total of eleven studies with 513 children were included. The Gross Motor Function Measure-88 (GMFM-88) D/E scores (MD = 8.14, 95%CI 6.26 to 10.02, P < 0.001), GMFM-88 B score (MD = 8.77, 95%CI 4.00 to 13.53, P < 0.001), modified Ashworth Scale (MAS) score (MD = -1.05, 95%CI -1.25 to -0.84, P < 0.001), Kyphosis angle (MD = -10.67, 95%CI -12.21 to -9.13, P < 0.001), Cobb's angle (MD = -2.66, 95%CI -3.38 to -1.93, P < 0.001), step length (MD = 3.35, 95%CI 1.81 to 4.90, P < 0.001), walking speed (MD = 0.09, 95%CI 0.05 to 0.14, P < 0.001) and GMFM score at six weeks follow-up (MD = 4.84, 95%CI 1.90 to 7.77, P = 0.001) were better in FES group than in the control group. There was no significant difference in MAS score between two groups after six weeks of follow-up (MD = 0.04, 95%CI -0.30 to 0.37, P = 0.84). Conclusion:FES could improve the lower-limb and trunk function of children with cerebral palsy, however, the long-term effect of relieving muscle spasm was not significant.

Objective: To compare the efficacy and safety of pro-urokinase and reteplase in the treatment of patients with acute ST elevation myocardial infarction (STEMI). Methods: STEMI patients, who received intravenous thrombolytic therapy in Henan STEMI registry between September 2016 and August 2018, were eligible for this study. A total of 5479 patients from 66 hospitals were screened and patients were divided into pro-urokinase group (n=638) and reteplase group (n=702) according to thrombolytic drugs. Data including patient demographics, risk factors, medical histories, patient information at admission, in-hospital treatment, time delays, and clinical events were collected. The clinical recanalization rate, in-hospital mortality, in-hospital death or treatment withdrawal, in-hospital main adverse cardiovascular and cerebrovascular events (MACCE, death or treatment withdrawal, congestive heart failure, reinfarction and ischemic stroke) and post-thrombolysis bleeding were compared between the two groups. Bleeding events were evaluated with Bleeding Academic Research Consortium (BARC) criteria. Results: The median age [61.8 (53.2, 69.0) vs. 62.6 (52.1, 69.8), P=0.833] or the proportion of women [23.0% (147/638) vs. 25.1% (176/702), P=0.385] were similar between the pro-urokinase and reteplase groups. Clinical recanalization rates were similar between the pro-urokinase and reteplase groups [82.1% (524/638) vs. 84.9% (596/702), P=0.172], and there was no difference in the median time from onset to thrombolysis [194.5 (135.0,290.0) min vs. 190 (126.0,292.0) min, P=0.431] and the median recanalization time [95 (67.5,120.0) min vs. 95 (71.0,119.0) min, P=0.561] between the two groups. There was no significant difference in in-hospital mortality [5.5% (35/638) vs. 5.1% (36/702), P =0.770], in-hospital all-cause mortality, treatment withdrawal [8.9% (57/638) vs.7.7% (54/702), P=0.410], and in-hospital MACCE [13.0% (83/638) vs. 10.4% (73/702), P=0.137] between pro-urokinase and reteplase groups. However, the incidence of post-thrombolysis bleeding was significantly higher in reteplase group than in pro-urokinase group [7.8% (55/702) vs. 3.8% (24/638), P=0.002]. Further analysis found that the incidence of oral bleeding and the BARC grades 1-2 bleeding were significantly higher in reteplase group than in pro-urokinase group, whereas the incidence of cerebral hemorrhage was similar between the two groups [0.6% (4/638) vs. 0.4% (3/702), P=0.715]. The comparison of efficacy and safety outcomes between the two groups after adjusting for baseline characteristics using general linear mixed models was consistent with those before the adjustment. There was no significant difference in in-hospital mortality, in-hospital death or treatment withdrawal, in-hospital MACCE after adjusting for baseline characteristics and post-thrombolysis bleeding between the two groups. Conclusions: Pro-urokinase and reteplase have similar clinical efficacy in the treatment of STEMI. In terms of safety, the incidence of cerebral hemorrhage is similar, while the incidence of BARC grades 1-2 bleeding and oral bleeding is higher in reteplase group than in pro-urokinase group, which has no impact on in-hospital outcomes.

【Objective】 To explore the regulatory mechanism of miR-204-3p targeting EphB2 gene on proliferation, apoptosis and invasion of NSCLC. 【Methods】 A549 cells were cultured and divided into 5 groups: NC mimic group, miR-204-3p mimic group, OE NCgroup, OE EphB2 group, miR-204-3p mimic+ OE EphB2 group. MTT, flow cytometry, Transwell and scratch test were used to detect cell proliferation, cycle, apoptosis, invasion and migration. Double Luciferase Report was used to analyze the targeting relationship between mir-204-3p and EphB2. The mRNA and protein expression of miR-204-3p, EphB2 were detected by qPCR and WB. 【Results】 Innon-small lung cancer cells, the binding site of mir-204-3p and EphB2 3'UTR region, the high expression of miR-204-3p significantly inhibited the expression of EphB2 mRNA and protein(P<0.01). Compared with the Negtively control group(NC mimic group), the proliferation of A549 cells in miR-204-3p mimicgroup were significantly decrease(P<0.05), and the apototic rate was significantly increased(P<0.05). Also, the cell migration and invasion ability were also decreased significantly(P<0.05). Transfection of Ephb2 reversed the above changes. In addition, in non-small cell lung cancer tissues, miR-204-3p was negatively correlated with EphB2 expression(r=0.636, P<0.001), and the overall survival was shorter in EphB2 high expression groups than that in low expression groups(logrank χ²=3.899, P=0.049) . 【Conclusion】 MiR- 204- 3p inhibits proliferation, migration and invasion of non-small lung cancer cells and induces apoptosis by down-regulating EphB2.

BACKGROUND: Human infections with zoonotic coronaviruses (CoVs), including severe acute respiratory syndrome (SARS)-CoV and Middle East respiratory syndrome (MERS)-CoV, have raised great public health concern globally. Here, we report a novel bat-origin CoV causing severe and fatal pneumonia in humans. METHODS: We collected clinical data and bronchoalveolar lavage (BAL) specimens from five patients with severe pneumonia from Wuhan Jinyintan Hospital, Hubei province, China. Nucleic acids of the BAL were extracted and subjected to next-generation sequencing. Virus isolation was carried out, and maximum-likelihood phylogenetic trees were constructed. RESULTS: Five patients hospitalized from December 18 to December 29, 2019 presented with fever, cough, and dyspnea accompanied by complications of acute respiratory distress syndrome. Chest radiography revealed diffuse opacities and consolidation. One of these patients died. Sequence results revealed the presence of a previously unknown β-CoV strain in all five patients, with 99.8% to 99.9% nucleotide identities among the isolates. These isolates showed 79.0% nucleotide identity with the sequence of SARS-CoV (GenBank NC_004718) and 51.8% identity with the sequence of MERS-CoV (GenBank NC_019843). The virus is phylogenetically closest to a bat SARS-like CoV (SL-ZC45, GenBank MG772933) with 87.6% to 87.7% nucleotide identity, but is in a separate clade. Moreover, these viruses have a single intact open reading frame gene 8, as a further indicator of bat-origin CoVs. However, the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV, indicating that these viruses might use the same receptor. CONCLUSION A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans.
