Fuxiong has a long history of cultivation. Since its first record in the Beneficial Formulas from the Taiping Imperial Pharmacy of the Song Dynasty, Fuxiong had always been used by ancient physicians and became a preponderant variety for some reasons during the periods of the Ming Dynasty, Qing Dynasty, and Republic of China. However, as for modern use, only Chuanxiong Rhizoma is valued, and the medicinal value of Fuxiong is gradually being overlooked. This article systematically researches the nomenclature, producing area, origin, and efficacy of Fuxiong, proving that the planting technology of Fuxiong matured in the Song Dynasty at the latest, slightly later than the emergence of Chuanxiong Rhizoma in the Sui and Tang Dynasties. Over the years, the producing area of Fuxiong has not undergone significant changes, and it is mainly cultivated within Jiangxi province. According to the analysis of the origin of Xiongqiong, combined with modern genetic research, it can be basically clarified that the early source of Xiongqiong may not be single. With the popularization of cultivation, Chuanxiong Rhizoma became a Dao-di herb earliest, gradually replacing Xiongqiong and being recognized clinically. After cultivation, the polyploidy of Chuanxiong Rhizoma varieties formed stable inheritance, forming the later Fuxiong. Medical experts have gradually deepened their understanding of the efficacy of Fuxiong. Initially, they believed that it was a substitute for Chuanxiong Rhizoma and had weaker efficacy than Chuanxiong Rhizoma. Medical experts in Jin and Yuan Dynasties such as Zhu Danxi and Dai Sigong believed that Fuxiong was good at relieving stagnation. Books and records of materia medica in the Ming and Qing Dynasties explicitly proposed the great ability of Fuxiong to relieve stagnation. Fuxiong should be distinguished from Chuanxiong Rhizoma when applied, and the application differences should be clearly reflected in medical records. Based on the comprehensive research in this article, it can be concluded that although most of ancient physicians have attached great importance to genuineness of Chuanxiong Rhizoma, Fuxiong, as a dominant variety of traditional application, has a clear historical context and significant efficacy characteristics, worthy of further in-depth study.

Damarane-type triterpene saponins are the main active ingredients in Gynostemma pentaphyllum (Thunb.) Makino. By using D101 macroporous adsorption resin and silica gel open-columns, C18 medium-pressure column chromatography, and preparative high performance liquid chromatography, we isolated four compounds from the leaves of G. pentaphyllum planted in Guangxi Zhuang Autonomous Region. Their structures were determined by comprehensive analyses of MS, NMR data and circular dichroism spectroscopy and identified as (3β,12β)-dihydroxy-25-peroxyhydrohydrodammarane-20,23-diene-3-O-[β-D-glucopyranosyl(1→2)]-β-D-glucopyranoside (1), (3β,12β,24S)-trihydroxydammarane-20,25-diene-3-O-[β-D-glucopyranosyl(1→2)]-β-D-glucopyranoside (2), (3β,20α)-dihydroxy-24-en-12β,22S-epoxydammarane-3-O-[β-D-glucopyranosyl(1→2)]-β-D-glucopyranoside (3), (3β,12β,20S)-trihydroxydammarane-24-en-3-O-[6-O-acetyl-β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl]-20-O-β-D-xylopyranosyl(1→3)-α-L-rhamnopyranosyl (1→6)-β-D-glucopyranoside (4). Compounds 1-4 are new dammarane-type triterpene saponins.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Many therapies are effective in treating varicoceles, including dilation of the pampiniform plexus in males. The most common method of treatment is varicocelectomy. We aimed to assess an alternative technique (microsurgical spermatic [distal end]-superficial or inferior epigastric vein anastomosis) that preserves the normal blood flow pattern for varicocele treatment. We retrospectively analyzed 27 men with varicocele between October 2019 and July 2020. All patients underwent microsurgical spermatic (distal end)-superficial or inferior epigastric vein anastomosis. The prognosis was reviewed retrospectively with an additional survey conducted 3 months after surgery. The mean ± standard deviation of the age was 26.1 ± 7.3 years in patients with microsurgical spermatic (distal end)-superficial or inferior epigastric vein anastomosis. The maximum diameter of the varicocele vein, perineal pain score, sperm density, and forward movement of sperm improved over 3 months after surgery. Microsurgical spermatic (distal end)-superficial or inferior epigastric vein anastomosis is a safe and efficient surgical treatment for varicoceles.

Six new prenylated flavonoid glycosides, including four new furan-flavonoid glycosides wushepimedoside A-D (1-4) and two new prenyl flavonoid derivatives wushepimedoside E-F (5-6), and one know analog epimedkoreside B (7) were isolated from biotransformation products of the aerial parts of Epimedium wushanense. Their structures were elucidated according to comprehensive analysis of HR-MS and NMR spectroscopic data, and the absolute configurations were assigned using experimental and calculated electronic circular dichroism (ECD) data. The regulatory activity of compounds 1-7 on the production of testosterone in primary rat Leydig cells were investigated, and 4 and 5 exhibited testosterone production-promoting activities. Molecular docking analysis suggested that bioactive compounds 4 and 5 showed the stable binding with 3β-HSD and 4 also had good affinity with Cyp17A1, which suggested that these compounds may regulate testosterone production through stimulating the expression of the above two key proteins.

Objective: To evaluate the immunogenicity of group A+C meningococcal polysaccharide conjugate vaccine in infants under 2 years old. Methods: From March 2017 to June 2018, 1 932 healthy infants in Biyang County, Henan Province, who were not vaccinated with meningococcal meningitis vaccine and whose axillary temperature was ≤37.0 ℃, were recruited as participants. The 3 months and 6-11 months old infants were allocated to the experiment group and the control group in a ratio of 1∶1. Infants aged 12-23 months were allocated to the 1-dose group, the 2-dose group and the control group in a ratio of 1∶1∶1, with 276 infants in each group. The infants in the experiment group were intramuscularly injected with freeze-dried group A+C meningococcal polysaccharide conjugate vaccine to be evaluated, and infants in the control group received intramuscular injection of commercially available freeze-dried group A+C meningococcal conjugate vaccine. The venous blood of infants was collected 30 days before the first dose and after the last dose of inoculation, and the antibody seroconversion of each group was determined and compared. Results: The completion rate of immunogenicity study was 95.2% (1 839/1 932). Before inoculation, there was no statistical difference in the geometric mean titer and positive rate of group A+C antibodies between the experiment group and the control group in 3 months and 6-11 months old infants (all P values >0.05). The geometric mean titers and positive rate of group A antibodies in the 1-dose group were higher than those in the control group (all P values <0.05), but there was no statistical difference between the 2-dose group and the control group (all P values >0.05) in infants aged 12-23 months. After inoculation, the differences (95%CI) in the positive conversion rate of group A+C antibodies between the experiment group and the control group were -0.12% (-6.01%-5.77%) and 0.82% (-4.23%-5.86%) in the 3 months old infants. At the age of 6-11 months, the differences were 6.75% (1.71%-11.79%) and -4.32% (-8.73%-0.08%), respectively. At the age of 12-23 months, the differences were 1.02% (-3.80%-5.83%) and -4.40% (-7.79%- -1.01%) in the 2-dose group and -7.22% (-12.90%- -1.54%) and -18.61% (-23.75%- -13.46%) in the 1-dose group, respectively. The geometric mean titers of group A+C antibodies in the 3 months old infants were 48.50 and 63.12, respectively, which had no significant difference from the control group (43.02 and 57.99, respectively) (both P values <0.05). The geometric mean titers of group A+C antibodies in the 6-11 months and 12-23 months old infants were 84.09 and 92.51 (2-dose group), which were higher than those in the corresponding control group (43.10 and 61.83, respectively) (all P values <0.001). Conclusion: Group A+C meningococcal conjugate vaccine has good immunogenicity in infants under 2 years old.

AIM:To evaluate the underlying aetiology and clinical characteristics of retinal detachment(RD)in school-age pediatric monocular RD.METHODS:Patients with RD and contralateral blind(monocular RD)aged 7-14 years, from November 2015 to May 2021 in our hospital were retrospectively reviewed. Demographic characteristics and etiology of RD, clinical type, surgical modality, type of intraocular tamponade, pre-and postoperative visual and anatomical outcomes were recorded and evaluated.RESULTS: There were 27 children(27 eyes)with monocular RD at least 6mo follow-up. The average age at presentation was 10.63±2.30 years. Familial exudative vitreoretinopathy(FEVR)(11/27, 41%), postoperative congenital glaucoma(6/27, 22%)and Stickler syndrome(3/27, 11%)were main underlying etiologies. Among them, rhegmatogenous retinal detachment(RRD)comprised 78%(21/27)of the patients, of which 81% patients(17/21)had proliferative vitreoretinopathy(PVR)C3 or worse. Pars plana vitrectomy(PPV)was done in 85%(23/27)of the patients, of which 83%(19/23)received silicone oil tamponade. Best corrected visual acuity(BCVA, LogMAR)worse than 1.7 was seen in 78%(21/27)of the patients at final visit, and 82%(22/27)had reattached retina, but 41%(11/27)of the patients remained status of silicone oil tamponade at last visit.CONCLUSION:School-age pediatric monocular RD is often associated with underlying congenital or hereditary conditions, and often presented with severe RD and severe PVR reaction which needed vitrectomy combined with silicon oil tamponade, and with poor visual and anatomical short-term prognosis.

Objective: To investigate the safety, feasibility and short-term efficacy of total laparoscopic loop ileostomy reversal in patients after resection of rectal cancer. Methods: The clinical data of 20 patients who underwent total laparoscopic loop ileoscopic loop ileostomy after radical resection of rectal cancer at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, or Beijing Chaoyang District Sanhuan Cancer Hospital from October 2019 to June 2020 were collected and retrospectively analyzed. Results: All patients had successfully underwent total laparoscopic ileostomy reversal without conversion to open surgery or discontinued operation. No perioperative related death cases were found. In the whole group, the median operation time was 97 (60-145) minutes and the median intraoperative blood loss was 20 (10-100) milliliters. The median Visual Analogue Scale (VAS) score was 1.9 (1-5) one day after the operation. Nobody needed to use additional analgesic drugs. The median time to grand activities was 25 (16-42) hours, the median time to flatus was 44 (19-51) hours, and the median hospitalization after operation was 6.9 (5-9) days. No patients underwent operation related complications such as operative incision infection, abdominal and pelvic infection, intestinal obstruction, anastomotic leakage, bleeding and so on. Conclusions: Total laparoscopic loop ileostomy reversal appears to be safe, feasible and with promising efficacy for selected patients.

Aim To investigate the effect of astragalin (AG) on airway inflammation in asthmatic mice and its mechanism. Methods Fifty SPF male mice were randomly divided into normal group, asthma model group, and astragalin low (AG25), medium (AG50), and high (AG100) dose groups. A mouse model of asthma was prepared by egg albumin inhalation, the number of cells was counted by Diff-Quik staining after collecting bronchoalveolar lavage fluid (BALF), and IL4, 5, and 13 levels in BALF were measured by ELISA. The inflammatory changes in mouse lung tissues were observed using HE staining. Reactive oxygen species (ROS) levels were measured using a DCFH-DA probe, and superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were measured by colorimetry. IL-4, IL-5, IL-13, NOX2, p47phox, p-NF-κBp65, NF-κBp65, IκBα, p-IκBα and β-actin expressions in lung tissues were detected by Western blot. Results AG significantly reduced the number of inflammatory cells and total cells in BALF, decreased IL-4, IL-5, and IL-13 contents in BALF and lung tissues, and reduced inflammatory cell infiltration in lung tissues. AG inhibited nicotinamide adenine dinucleotide phosphate oxidase 2 (NOX2) and p47phox expression, decreased ROS levels and MDA levels, increased SOD activity, and inhibited IκBα and NF-κBp65 phosphorylation. Conclusion AG attenuates airway inflammation in asthma by modulating the oxidative stress response through the NOX2/ROS/NF-κB signaling pathway.

Objective::To screen out the effective components of Salvia miltiorrhiza by establishing an in vitro model of pulmonary epithelial mesenchymal transformation. Method::Different concentrations of salvianolic acid A (10, 20, 40, 80, 160 μmol·L^-1), salvianolic acid B (10, 20, 40, 80, 160 μmol·L^-1), tanshinol (10, 20, 40, 80, 160 μmol·L^-1), tanshinoneⅡ_A (10, 20, 40, 80, 160 μmol·L^-1) and the blank group were applied to A549 cell, cell proliferation and cytotoxicity assay (MTS) were used to detect the proliferation effect of menthol on A549 cells.After screening the safe concentration of the active ingredients of salvia miltiorrhiza by MTS, cells were divided into blank group, model group, salvianolic acid A group, salvianolic acid B group, tanshinol group and tanshinoneⅡ_A.Then, the inhibitory effect of the active ingredients of salvia miltiorrhiza on the proliferation of A549 cells induced by TGF-β₁ was detected by MTS. Enzyme linked immunosorbent assay (ELISA) method to detect salvia miltiorrhiza effective component of fiber protein(FN), collagen type I (COL-Ⅰ) expression. Based on the above results, the active components of salvia miltiorrhiza, which have best inhibition were screened out, and their effects on the expression of E-calcium-viscosity (E-Cad) protein were detected by Western blot. Result::Compared with blank group, salvianolic acid A 40 μmol·L^-1, salvianolic acid B 160 μmol·L^-1, tanshinol 160 μmol·L^-1 had toxic effects on A549 cells (P<0.05). In the non-toxic concentration range, compared with the model group, salvianolic acid A 10, 20 μmol·L^-1, salvianolic acid B 80 μmol·L^-1 showed inhibition effect after 24 h culture (P<0.05). After 72 h culture, salvianolic acid A 5, 10, 20 μmol·L^-1, salvianolic acid B 40, 80 μmol·L^-1inhibition effect was very significant (P<0.01).
