OBJECTIVE: To evaluate the effect and safety of Chinese medicine (CM) Fuzheng Huazhuo Decoction (FHD) in treating patients with coronavirus disease 2019 (COVID-19) who persistently tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). METHODS: This retrospective cohort study was conducted at Shanghai New International Expo Center shelter hospital in China between April 1 and May 30, 2022. Patients diagnosed as COVID-19 with persistently positive SARS-CoV-2 reverse transcription-polymerase chain reaction (RT-PCR) test results for ⩾8 days after diagnosis were enrolled. Patients in the control group received conventional Western medicine (WM) treatment, while those in the FHD group received conventional WM plus FHD for at least 3 days. The primary outcome was viral clearance time. Secondary outcomes included negative conversion rate within 14 days, length of hospital stay, cycle threshold (Ct) values of the open reading frame 1ab (ORF1ab) and nucleocapsid protein (N) genes, and incidence of new-onset symptoms during hospitalization. Adverse events (AEs) that occurred during the study period were recorded. RESULTS: A total of 1,765 eligible patients were enrolled in this study (546 in the FHD group and 1,219 in the control group). Compared with the control group, patients receiving FHD treatment showed shorter viral clearance time for nucleic acids [hazard ratio (HR): 1.500, 95% confidence interval (CI): 1.353-1.664, P<0.001] and hospital stays (HR: 1.371, 95% CI: 1.238-1.519, P<0.001), and a higher negative conversion rate within 14 days (96.2% vs. 82.6%, P<0.001). The incidence of new-onset symptoms was 59.5% in the FHD group, similar to 57.8% in the control group (P>0.05). The Ct values of ORF1ab and N genes increased more rapidly over time in the FHD group than those in the control group post-randomization (ORF1ab gene: β =0.436±0.053, P<0.001; N gene: β =0.415 ±0.053, P<0.001). The incidence of AEs in the FHD group was lower than that in the control group (24.2% vs. 35.4%, P<0.001). No serious AEs were observed. CONCLUSION FHD was effective and safe for patients with persistently positive SARS-CoV-2 PCR tests. (Registration No. ChiCTR2200063956).

Objective To understand the prevalence characteristics of influenza and changes of influenza virus strains,and provide reference for the prevention and control of influenza in the province.Methods Surveillance da-ta about influenza in Hunan Province from 2014 to 2023 were exported from China Influenza Surveillance Informa-tion System.Differences in the percentage of influenza-like illness(ILI)cases(percentage of influenza-like cases[ILI％]in outpatient and emergency department visits)among different years and different populations,as well as the positive rate of influenza virus in ILI specimens were compared.Results From 2014 to 2023,over 2.65 million cases of ILI were reported,with an ILI％of 4.70％.ILI％among different years presented statistically significant differences(P＜0.001).People aged 0-14 years old were the main population with ILI,accounting for 82.90％.The positive rate of influenza virus in ILI specimens was 14.14％,the positive rate of influenza virus among diffe-rent years and age groups were both significantly different(both P＜0.001).The main prevalent influenza strains from 2014 to 2023 included types A(H1N1),A(H3N2),B(Victoria),and B(Yamagata),alternating among di-fferent years.However,type B(Yamagata)strains were not detected from 2020 to 2023.There were basically two influenza prevalence seasons every year,namely winter-spring and summer.Conclusion People＜15 years old are the main population of influenza,and the prevalence peaks are in winter-spring and summer.From 2021 to 2023,the prevalence alternates mainly among 3 types:A(H1N1),A(H3N2),and B(Victoria).

Objective To determine the role of AAMP in osteosarcoma cells and explore the mechanism of invasion and metastasis of osteosarcoma cells regulated by AAMP through the YAP signaling pathway.Methods Public sequencing data analysis was used to explore the correlation between AAMP and osteosarcoma.q-PCR,Western blot,and immunohistochemistry were used to detect the expression levels of osteosarcoma cell-related molecules.CCK-8 was used to detect cell proliferation ability.Transwell and wound healing assays were used to detect the invasive and metastatic abilities of osteosarcoma cells.Immunofluorescence was used to detect the cell localization and expression levels of related molecules.Results High expression of AAMP was negatively correlated with the prognosis of patients with osteosarcoma(P<0.05),and the expression of AAMP in patients with metastatic osteosarcoma increased(P<0.05).Compared with the control group,the AAMP interference group showed significantly decreased migratory,invasive,and EMT activities(P<0.05).The expression of p-CFL1 reduced after the knockdown of AAMP,and the cell plate pseudopods decreased significantly(P<0.05).A positive correlation was found between the expression levels of AAMP and YAP in osteosarcoma cells(P<0.05).Interfering with YAP expression can affect the migration and invasion of osteosarcoma cells.Conclusion AAMP promotes osteosarcoma cell metastasis by regulating the YAP signaling pathway,suggesting that AAMP may be a key molecule in promoting invasion and metastasis of osteosarcoma.

AIM To investigate the effects of Zuogui Jiangtang Tongmai Recipe on necroptosis pathway in a rat model of type 2 diabetes mellitus(T2DM)complicated with cerebral infarction(CI).METHODS The SD rats were randomly divided into the sham operation group,the model group,the metformin group(0.045 g/kg),and the low,medium and high dose Zuogui Jiangtang Tongmai Recipe groups(6.5,13,26 g/kg),with 9 rats in each group.In contrast to rats of the sham operation group,rats of the other groups were given 4 weeks feeding of high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin to establish a T2DM rat model with one week stable blood glucose,followed by gavage of corresponding drugs 3 days before the establishment of the middle cerebral artery occlusion(MCAO)model.After 7 days of administration,the rats had their CI injury assessed by mNSS method and TTC staining;their level of blood glucose detected by blood glucose meter;their levels of glycated serum protein,serum TNF-α and IL-1β detected by ELISA;their cerebral mRNA expressions of FADD,RIPK1,RIPK3 and MLKL detected by RT-qPCR;and their cerebral protein expressions of FADD,p-RIPK1,p-RIPK3 and p-MLKL detected by Western blot.RESULTS Compared with the sham operation group,the model group displayed increased levels of blood glucose value,glycosylated serum protein,neurological function score,cerebral infarction volume,cerebral FADD,RIPK1,RIPK3 and MLKL mRNA expressions,cerebral FADD,p-RIPK1,p-RIPK3 and p-MLKL protein expressions,serum TNF-α and IL-1β levels(P＜0.01);and more disordered and morphologically diverse neurons with smaller nucleus.Compared with the model group,the groups intervened with medium or high dose Zuogui Jiangtang Tongmai Recipe,or metformin shared improvement in terms of the aforementioned indices(P＜0.05,P＜0.01);and more neurons with regular morphology neat arrangement,and reduced cell gap.CONCLUSION Zuogui Jiangtang Tongmai Recipe can improve the neurological dysfunction of the rat model of T2DM complicated with CI,which may associate with the inhibited activation of necroptosis signaling pathway.

OBJECTIVE: To explore clinical effect of percutaneous endoscopic posterolateral trans-facet lumbar interbody fusion (PE-PTLIF) in treating degenerative lumbar spondylolisthesis. METHODS: The data of 38 patients with degenerative lumbar spondylolisthesis treated with PE-PTLIF from December 2019 to June 2021 were retrospectively analyzed, including 18 males and 20 females, aged from 39 to 75 years old with an average of (60.2±8.9) years old;1 patient with L_3,4, 23 patients with L_4,5, 14 patients with L₅S₁;29 patients with degreeⅠand 9 patients with degreeⅡaccording to Meyerding grading. Operative time, intraoperative blood loss, drainage volume, postoperative hospital stay and complcations were observed, visual analogue scale (VAS) was used to evaluate degree of lumbar and leg pain before operation, 3 d and 3, 6 and 12 months after operation, respectively. Oswestry disability index (ODI) was used to evaluate degree of low back pain dysfunction before operation, 3, 6 and 12 months after operation. The modified MacNab standard was used to evaluate clinical efficacy at 12 months after operation. Dural sac cross-sectional area (DSCSA), intervertebral disc height (IDH), lumbar spondylolisthesis rate (SR), lumbar lordosis angle (LL) and segmental lordosis angle (SL) were compared before operation and 12 months after operation. Interbody fusion at 12 months was evaluated according to Bridwell intervertebral fusion standard. RESULTS: All patients were followed up for 13 to 28 months with an average of (18.47±4.12) months. The operative time was (181.68±19.34) min, intraoperative blood loss was (152.87±57.03) ml, drainage volume was (48.18±11.43) ml, and postoperative hospital stay was (9.45±2.18) d and 3 patients occurred complications. VAS of lumbar pain before operation, 3 days, 3, 6 and 12 months after operation were (6.68±1.16), (4.32±1.13), (2.18±0.70), (1.89±0.56) and (1.57±0.72), respectively. VAS of leg pain were (6.24±1.42), (2.95±1.09), (1.76±0.71), (1.68±0.74) and (1.26±0.69) respectively. Preoperative and postoperative 3, 6 and 12 months of ODI were (63.21±11.21) %, (25.24±6.46) %, (20.97±6.26) % and (17.73±5.88) %, respectively. Postoperative VAS of lumbar and leg pain and ODI were significantly lower than those of preoperative time points (P<0.05). According to the modified MacNab standard, 23 patients got excellent result, 10 good, 3 fair, and 2 poor at 12 months after operation. Postoperative DSCSA, IDH, SR, LL and SL at 12 months were (128.32±21.95) mm², (11.19±1.66) mm, (4.44±2.19)%, (49.32±5.63)°, (9.16±1.90)°, respectively, and were improved compared with preoperative [(58.36±18.11) mm², (8.19±2.06) mm (18.43±4.78) %, (42.38±4.94) ° and (8.06±2.06) °] (P<0.05). Thirty-four patients obtained gradeⅠfusion, 3 patients woth gradⅡfusion and 1 patient with grade Ⅲ fusion at 12 months after operation according to Bridwell intervertebral fusion standard. CONCLUSION PE-PTLIF could provide effective method for the treatment of gradeⅠand gradeⅡdegenerative lumbar spondylolisthesis. It has advantages of less bleeding, sufficient decompression, fast postoperative recovery and high fusion rate, which could effectively relieve lumbar and leg pain, restore vertebral space height and improve lumbar sagittal balance. PE-PTLIF is a safe and minimally invasive surgery.

PURPOSE: Different arch structures may cause different foot function injuries. In the past, the arch structure and flexibility of the foot were often defined by the height of the arch, and there was no three-dimensional (3D) structure classification method. In order to form a more complete 3D description, we propose a new classification system of arch volume flexibility (AVF), and then use this new classification system to investigate the relationship between the AVF and arch index (AI), and the arch height flexibility (AHF) and AI, respectively. METHODS: It is proposed to recruit 180 young male adults for the test. We obtained arch volume and AI through 3D scanning and obtained the navicular height through manual measurement. Based on these data, we calculated the AHF and the AVF. Using the quintile method, these arches are divided into very stiff, stiff, neutral, flexible, and very flexible. According to AI value, all arches were divided into cavus, rectus, and planus. The distribution of AVF was compared using χ² goodness of fit test. The spearman correlation test was used to compare the AHF and AVF. A p < 0.05 indicates that the difference is statistically significant. RESULTS: All participants' plantar data was obtained through 3D scanning, but only 159 of them were complete, so only 318 feet had valid data. The left AHF is (21.23 ± 12.91) mm/kN, and the right AHF is (21.71 ± 12.69) mm/kN. The AVF of the left foot arch is (207.35 ± 118.28) mm³/kg, while the right one is (203.00 ± 117.92) mm³/kg, and the total AVF of the arch was (205.17 ± 117.94) mm³/kg. There was no statistical difference in the AVF between the left and right feet for the same participant (n = 159, p = 0.654). In cavus, the percentage of arch with AVF is 21.4% (very stiff), 21.4% (stiff), 14.3% (neutral), 7.1% (flexible), and 35.7% (very flexible). In rectus, the percentage of arch with AVF is 23.9% (very stiff), 19.6% (stiff), 14.7% (neutral), 24.5% (flexible), and 17.2% (very flexible). In planus, the percentage of arch with AVF is 14.9% (very stiff), 20.6% (stiff), 27.0% (neutral), 16.3% (flexible), and 21.3% (very flexible). Moreover, the correlation between AHF and AVF is not significant (p = 0.060). CONCLUSION In cavus, rectus, and planus, different AVF accounts different percentage, but the difference is not statistically significant. AVF is evenly distributed in the arches of the feet at different heights. We further found the relationship between AHF and AVF is not significant. As a 3D index, AVF may be able to describe the flexibility of the arch more comprehensively than AHF.

Objective: To evaluate the prognostic value of left ventricular ejection fraction (LVEF) reserve assessed by gated SPECT myocardial perfusion imaging (SPECT G-MPI) for major adverse cardiovascular event (MACE) in patients with coronary artery disease. Methods: This is a retrospective cohort study. From January 2017 to December 2019, patients with coronary artery disease and confirmed myocardial ischemia by stress and rest SPECT G-MPI, and underwent coronary angiography within 3 months were enrolled. The sum stress score (SSS) and sum resting score (SRS) were analyzed by the standard 17-segment model, and the sum difference score (SDS, SDS=SSS-SRS) was calculated. The LVEF at stress and rest were analyzed by 4DM software. The LVEF reserve (ΔLVEF) was calculated (ΔLVEF=stress LVEF-rest LVEF). The primary endpoint was MACE, which was obtained by reviewing the medical record system or by telephone follow-up once every twelve months. Patients were divided into MACE-free and MACE groups. Spearman correlation analysis was used to analyze the correlation between ΔLVEF and all MPI parameters. Cox regression analysis was used to analyze the independent factors of MACE, and the optimal SDS cutoff value for predicting MACE was determined by receiver operating characteristic curve (ROC). Kaplan-Meier survival curves were plotted to compare the difference in the incidence of MACE between different SDS groups and different ΔLVEF groups. Results: A total of 164 patients with coronary artery disease [120 male; age (58.6±10.7) years] were included. The average follow-up time was (26.5±10.4) months, and a total of 30 MACE were recorded during follow-up. Multivariate Cox regression analysis showed that SDS (HR=1.069, 95%CI: 1.005-1.137, P=0.035) and ΔLVEF (HR=0.935, 95%CI: 0.878-0.995, P=0.034) were independent predictors of MACE. According to ROC curve analysis, the optimal cut-off to predict MACE was a SDS of 5.5 with an area under the curve of 0.63 (P=0.022). Survival analysis showed that the incidence of MACE was significantly higher in the SDS≥5.5 group than in the SDS<5.5 group (27.6% vs. 13.2%, P=0.019), but the incidence of MACE was significantly lower in the ΔLVEF≥0 group than in theΔLVEF<0 group (11.0% vs. 25.6%, P=0.022). Conclusions: LVEF reserve (ΔLVEF) assessed by SPECT G-MPI serves as an independent protective factor for MACE, while SDS is an independent risk predictor in patients with coronary artery disease. SPECT G-MPI is valuable for risk stratification by assessing myocardial ischemia and LVEF.
