Objective:To understand the prevalence and characteristics of Rhinovirus (HRV) infection in influenza-like Illness (ILIs) patients in Mianyang, Sichuan province, China.Methods:Throat swabs were collected from patients of ILIs in sentinel hospitals in Mianyang during 2021—2022. Real-time fluorescence quantitative PCR was used to detect 16 common pathogens. The VP4/VP2 coding region genes of HRV positive samples were amplified by nest PCR. The phylogeny, consistency and amino acid variation of different serotypes were analyzed and compared with reference sequences from GenBank database.Results:A total of 332 ILIs′ samples were collected with a virus detection rate of 58.73% (195/332) in Mianyang. Among them, 23 samples (23/332) were HRV-positive, and 18 VP4/VP2 sequences of HRV strains were successfully amplified. It was found that 13 HRV serotypes were detected in ILIs samples in Mianyang, which belonged to three genotypes, namely HRV-A (12 strains), HRV-B (5 strains) and HRV-C (1 strain).Conclusions:HRV was one of the pathogens of ILIs cases in Mianyang during 2021—2022, with HRV-A types as the dominant strains.

Prunellae Spica is the dried spica of Prunella vulgaris belonging to Labiatae and it is widely used in pharmaceutical and general health fields. As a traditional Chinese medicine cultivated on a large scale, it produces a large amount of non-medicinal parts, which are discarded because they are not effectively used. To analyze the chemical constituents in the different samples from spica, seed, stem, and leaf of P. vulgaris, and explore the application value and development prospect of these parts, this study used ultrahigh performance liquid chromatography-tandem quadrupoles time of flight mass spectrometry(UPLC-Q-TOF-MS/MS) to detect chemical constituents in different parts of P. vulgaris. As a result, 117 compounds were detected. Among them, 87 compounds were identified, including 32 phenolic acids, 8 flavonoids, and 45 triterpenoid saponins. Some new triterpenoid saponins containing the sugar chain with 4-6 sugar units were found. Further, multivariate statistical analysis was conducted on BPI chromatographic peaks of multiple batches of different parts, and the results showed that spica had the most abundant chemical constituents, including salviaflaside and linolenic acid highly contained in the seed and phenolic acids, flavonoids, and triterpenoid saponins in the stem and leaf. In general, the constituents in the spica were composed of those in the seed, stem, and leaf. UPLC was used to determine the content of 6 phenolic acids(danshensu, protocatechuic acid, protocatechuic aldehyde, caffeic acid, salviaflaside, and rosmarinic acid) in different parts. The content of other phenolic acids in the seed was generally lower than that in the spica except that of salviaflaside. The content of salviaflaside in the spica was higher than that in the stem and leaf, but the content of other phenolic acids in the spica was not significantly different from that in the stem. The content of protocatechuic aldehyde and caffeic acid in the spica was lower than that in the leaf. DPPH free radical scavenging method was used to detect the antioxidant activity of four parts, and there was no significant difference in the antioxidant activity between the spica and the stem and leaf, but that was significantly higher than the seed. Moreover, the antioxidant activity of these parts was correlated with the content of total phenolic acids. Based on the above findings, the stem and leaf of P. vulgaris have potential application value. Considering the traditional medication rule, it is feasible to use the whole plant as a medicine. Alternatively, salviaflaside, occurring in the seed, can be used as a marker compound for the quality evaluation of Prunellae Spica, if only using spica as the medicinal part of P. vulgaris, as described in the Chinese Pharmacopoeia(2020 edition).

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9%) were men. Among them, nearly two-thirds (62.5%) of the survivors were moderate, three (9.4%) were severe, and more than half (59.4%) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6% at 3 months to 15.8% at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1%) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

Tumors are new organisms formed by uncontrollable cell proliferation of local tissues driven by various oncogenic factors. The cause of tumors is unknown with life-threating outcome. Tumors can be classified into benign tumors, borderline tumors, and malignant tumors according to their pathological properties. Among them, malignant tumor is commonly known as cancer, with no specific medicines or reliable cure means, so this is a hot spot and difficult point in current medical research. In ancient literatures, there are many records about the efficacy of Chinese herbal medicine in treating tumor, and modern pharmacological researches have shown that more and more active ingredients of traditional Chinese medicine(TCM) have gradually highlighted their inhibitory effect on various types of tumor.

Objective: To investigate the efficacy and predictors of autologous hematopoietic stem cell transplantation (auto-HSCT) in the treatment of T lymphoblastic lymphoma (T-LBL) . Methods: 41 patients with T-LBL who underwent auto-HSCT from April 2006 to July 2017 in the Department of Hematology, the First Affiliated Hospital of Soochow University and the Department of Lymphoma, Peking University Cancer Hospital were analyzed retrospectively. Results: ①Among 41 patients, there were 30 males and 11 females with median age of 24 (11-53) years old. According to the Ann Arbor staging, 33 (80.5%) patients were in stage Ⅲ/Ⅳ. 12 (29.3%) patients have mediastinal involvement, and 20 (48.8%) patients have bone marrow (BM) involvement. Before transplantation, there were 26 (63.4%) patients who achieved first complete remission (CR(1)) , the other 15 (36.6%) patients were in the non-CR(1) group, and there were 29 (70.7%) patients in the low-intermediate risk group (IPI<3 scores) , the other 12 (34.1%) patients were in the middle-high risk group (IPI≥3 scores) . ②The median follow-up was 29 (3-98) months. The 3-year overall survival (OS) and progression-free survival (PFS) for 41 patients were (64.3±8.2) % and (66.0±7.8) %, respectively. 3-year cumulative recurrence rate (CIR) was (30.7±7.4) %, and 3-year non-recurring mortality (NRM) was (4.8±4.6) %. ③The 3-year OS of the CR(1) group and the non-CR(1) group were (83.4±7.6) % and (38.9±12.9) % (P=0.010) , and the 3-year PFS of two groups were (83.8±7.4) % and (40.0±12.6) % (P=0.006) , respectively. The 3-year CIR of these two groups were (16.2±7.4) % and (53.3±12.9) % (P=0.015) , and the 3-year NRM were 0 and (14.3±13.2) % (P=0.157) , respectively. ④The 3-year OS of the IPI low-intermediate risk group and the high-intermediate risk group were (76.9±8.4) % and (35.7±15.2) % (P=0.014) and the 3-year PFS were (77.4±8.2) % and (40.0±14.6) (P=0.011) , respectively. The 3-year CIR of these two groups were (18.1±7.3) % and (60.0±14.6) % (P=0.006) , and the 3-year NRM were (5.6±5.4) % and 0 (P=0.683) , respectively. The OS and PFS of patients with low-intermediate risk group were significantly higher than the other group. Conclusion: Auto-HSCT could improve the survival of T-LBL. Pre-transplant status and IPI score are important predictors for survival T-LBL patients with auto-HSCT.

Objective To assess the effectiveness of infectious source control at various stages of transmission control of schistosomiasis in Eryuan County of Yunnan Province, so as to provide insights into the further monitoring and management of infectious sources of schistosomiasis. Methods Wenbi Village, a plateau subtype region and Qiandian Village, a mountain subtype region in Eryuan County were selected as the study areas. The species, schistosome infection and transmission capability of infectious sources were investigated in Wenbi and Qiandian villages in 2011 and 2018 and were compared. Results Schistosome infections were detected in human, bovine, horse, dog and mouse in Qiandian Village in 2011, with positive rates of 1.19%, 0.91%, 1.25%, 3.13% and 0.95%, respectively, and human, bovine and dog were found to have schistosome infections, with positive rates of 0.76%, 1.66% and 9.30%, respectively. However, no infections were identified in human, bovine, horse, pig, dog, sheep or mouse in these two villages in 2018. A total of 731 wild feces were collected in both villages in 2011. In Qiandian Village, horse, bovine and dog feces accounted for 34.40%, 29.80% and 20.20% of all fecal samples, and dog and horse feces were found to have schistosome infections (11.94% and 6.90% positive rates, respectively). In Wenbi Village, dog, bovine and human feces accounted for 44.59%, 39.83% and 14.29% of all fecal samples, and dog, human and bovine feces were found to have schistosome infections (16.95%, 9.52% and 2.33% positive rates, respectively). In 2018, a total of 204 wild feces were collected in both villages, and no schistosome infections were identified. Sheep, dog and bovine feces accounted for 36.27%, 33.33% and 27.45% of all fecal samples in Qiandian Village, and dog, bovine and human feces accounted for 72.55%, 11.76% and 10.78% of all fecal samples in Wenbi Village. Conclusions A remarkable achievement has been obtained in the control of infectious sources of schistosomiasis in Eryuan County, and the role of human and bovine as the major infectious sources of schistosomiasis has been effectively controlled. In the future, the integrated strategy with emphasis on the control of infectious sources should be intensified, and the management of reservoir hosts including dog and mouse should be strengthened.

To evaluate the effectiveness and safety of Xinling Wan on patients with stable angina pectoris, a randomized, double-blinded, placebo parallel-controlled, multicenter clinical trial was conducted. A total of 232 subjects were enrolled and randomly divided into experiment group and placebo group. The experiment group was treated with Xinling Wan (two pills each time, three times daily) for 4 weeks, and the placebo group was treated with placebo. The effectiveness evaluation showed that Xinling Wan could significantly increase the total duration of treadmill exercise among patients with stable angina pectoris. FAS analysis showed that the difference value of the total exercise duration was between experiment group (72.11±139.32) s and placebo group (31.25±108.32) s. Xinling Wan could remarkably increase the total effective rate of angina pectoris symptom score, and the analysis showed that the total effective rate was 78.95% in experiment group and 42.61% in placebo group. The reduction of nitroglycerin dose was (2.45±2.41) tablets in experiment group and (0.50±2.24) tablets in placebo group on the basis of FAS analysis. The decrease of symptom integral was (4.68±3.49) in experiment group and (3.19±3.31) in placebo group based on FAS analysis. Besides, Xinling Wan could decrease the weekly attack time and the duration of angina pectoris. PPS analysis results were similar to those of FAS analysis. In conclusion, Xinling Wan has an obvious therapeutic effect in treating stable angina pectoris, with a good safety and a low incidence of adverse event and adverse reaction in experiment group.

IG-105, N-(2,6-dimethoxypyridine-3-yl)-9-methylcarbazole-3-sulfonamide, a novel antimicrotubule agent, showed potent anticancer activity in a variety of human tumor cells in vitro and in vivo. In order to characterize the metabolism and the possible drug-drug interaction of IG-105, we carried out a series of experiments. Drug metabolizing enzymes involved in IG-105 metabolism were investigated by using pooled human liver microsomes (HLMs) and recombinant cytochrome P450 isoforms (rP450s) respectively. The possible metabolites were analyzed by liquid chromatography-orbitrap-mass spectrometry (LC-Orbitrap-MS). The inhibitory effect of IG-105 on main P450 enzymes was also evaluated. The results showed that IG-105 can be metabolized by a series of rP450s, including CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4 and CYP3A5, with the major contribution enzymes being CYP1A2, CYP2B6, CYP2C19, and CYP3A. Three metabolites (M1-M3) were identified and demethylation was the major phase I metabolic reaction for IG-105. IG-105 moderately inhibited CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A enzyme activities with IC50 values of 6.42, 23.64, 0.39, 1.4, and 3.14 μmol·L-1, respectively. Since the biotransformation of IG-105 involves multiple enzymatic pathways, the compound is less likely to be a victim of a concomitantly used medicine which inhibits activity of one of the CYPs. However, as IG-105 showed medium to strong inhibition on CYP1A2, CYP2D6, CYP3A, and CYP2C19, caution is particularly needed when IG-105 is co-administrated with other anticancer drugs which are mainly metabolized by the above enzymes.
