Genetic transformation is a fundamental tool in molecular biology research of medicinal plants. Tailoring transgenic technologies to each distinct medicinal plant would necessitate a substantial investment of time and effort. Here, we present a simple hairy root transformation method that does not require sterile conditions, utilizing Agrobacterium rhizogenes strain K599 and the visible RUBY reporter system. Transgenic hairy roots were obtained for six tested medicinal plant species, roots or rhizomes of which have recognized medicinal value, spanning four botanical families and six genera (Platycodon grandiflorus, Atractylodes macrocephala, Scutellaria baicalensis, Codonopsis pilosula, Astragalus membranaceus, and Glycyrrhiza uralensis). Furthermore, two previously identified Glycyrrhiza uralensis UGTs that convert liquiritigenin into liquiritin in heterologous systems were studied in planta using the method. Our results indicate that overexpression of GuUGT1 but not GuUGT10 and Cas9-mediated knockout of GuUGT1 profoundly influenced the accumulation of liquiritin and isoliquiritin in licorice roots. Therefore, the method described here represents a simple, rapid and widely applicable hairy root transformation method that enables fast gene functional study in medicinal plants.

OBJECTIVE:
In Pakistan, traditional medicines are an important component of the medical system, with numerous varieties and great demands. However, due to the scattered resources and the lack of systematic collection and collation, adulteration of traditional Pakistani medicine (TPM) is common, which severely affects the safety of their medicinal use and the import and export trades. Therefore, it is urgent to systematically organize and unify the management of TPM and establish a set of standards and operable methods for the identification of TPM.
METHODS:
We collected and organized the information on 128 TPMs with regard to their medicinal parts, efficacy, usage, and genetic material, based on Pakistan Hamdard Pharmacopoeia of Eastern Medicine: Pharmaceutical Codex. The genetic information of TPM is summarized from national center for biotechnology information (NCBI) and global pharmacopoeia genome database (GPGD). Furthermore, we utilized bioinformatics technology to supplement the chloroplast genome (cp-genome) data of 12 TPMs. To build the web server, we used the Linux + Apache + MySQL + PHP (LAMP) system and constructed the webpage on a PHP: Hypertext Preprocessor (PHP) model view controller (MVC) framework.
RESULTS:
We constructed a new genomic database, the traditional Pakistani medicine genomic database (TPMGD). This database comprises five entries, namely homepage, medicinal species, species identification, basic local alignment search tool (BLAST), and download. Currently, TPMGD contains basic profiles of 128 TPMs and genetic information of 102 TPMs, including 140 cytochrome c oxidase subunit I (COI) sequences and 119 mitochondrial genome sequences from Bombyx mori, 1 396 internal transcribed spacer 2 (ITS2) sequences and 1 074 intergenic region (psbA-trnH) sequences specific to 92 and 83 plant species, respectively. Additionally, TPMGD includes 199 cp-genome sequences of 82 TPMs.
CONCLUSION
TPMGD is a multifunctional database that integrates species description, functional information inquiry, genetic information storage, molecular identification of TPM, etc. The database not only provides convenience for TPM information queries but also establishes the scientific basis for the medication safety, species identification, and resource protection of TPM.

Lingguizhugan Decoction (LGZG) demonstrates significant efficacy in treating various cardiovascular diseases clinically, yet its precise mechanism of action remains elusive. This study aimed to elucidate the potential mechanisms and effects of LGZG on isoproterenol (ISO) continuous stimulation-induced chronic heart failure (CHF) in mice, providing direct experimental evidence for further clinical applications. In vivo, continuous ISO infusion was administered to mice, and ventricular myocytes were utilized to explore LGZG?s potential mechanism of action on the ?1-adrenergic receptor (?1-AR)/Gs/G protein-coupled receptor kinases (GRKs)/?-arrestin signaling deflection system in the heart. The findings reveal that LGZG significantly reduced the messenger ribonucleic acid (mRNA) expression of hypertrophy-related biomarkers [atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP)] and improved cardiac remodeling and left ventricular diastolic function in mice with ISO-induced CHF. Furthermore, LGZG inhibited the overactivation of Gs/cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signaling and downregulated the downstream transcriptional activity of cAMP-response element binding protein (CREB) and the expression of the coactivator CBP/P300. Notably, LGZG downregulated the expression of ?-arrestin1 and GRK 2/3/5 while upregulating the expression of ?1-AR and ?-arrestin2. These results suggest that LGZG inhibits Gs/cAMP/PKA signaling and ?-arrestin/GRK-mediated desensitization and internalization of ?1-AR, potentially exerting cardioprotective effects through the synergistic regulation of the ?1-AR/Gs/GRKs/?-arrestin signaling deflection system via multiple pathways.

OBJECTIVE To analyze the metabolites of Zhideke granules and speculate its metabolic pathway in rats in vivo. METHODS Male SD rats were randomly divided into blank group and administration group (Zhideke granules, 9.45 g/kg); they were given ultrapure water or relevant medicine, twice a day, every 6-8 h, for 3 consecutive days. Serum, urine and feces samples of rats were collected, and their metabolites were identified by UPLC-Q-Exactive-MS technique after intragastric administration of Zhideke granules; their metabolic pathways were speculated. RESULTS After intragastric administration of Zhideke granules, 16 prototype components (i.g. irisflorentin, baicalin, chlorogenic acid) and 11 metabolites (i.g. hydration products of kaempferol or luteolin, methylation products of chlorogenic acid, and hydroxylation products of baicalin) were identified in serum, urine and feces of rats. Among them, 8 prototype components and 4 metabolites were identified in serum samples; 10 prototype components and 7 metabolites were identified in urine samples; 8 prototype components and 5 metabolites were identified in the fecal samples. CONCLUSIONS The metabolites of Zhideke granules in rats mainly include baicalin, irisflorentin,chlorogenic acid, and the main metabolic pathways included methylation, hydroxylation, glucuronidation.

OBJECTIVE To investigate the regulatory effect of autophagy on the resistance of human liver cancer cell Huh7 to lenvatinib. METHODS Using human liver cancer cell Huh7 as subject, the lenvatinib-resist cell model (Huh7-LR) was generated by the low-dose gradient method combined with long-term administration. The sensitivity of parental cell Huh7 and drug-resistant cell Huh7-LR to lenvatinib was detected by using CCK-8 assay and flow cytometry. Western blot assay and GFP-mCherry-LC3 plasmid transfection were performed to detect the expression levels of autophagic protein Beclin-1, autophagic adapter protein sequestosome 1 (p62), microtubule-associated protein 1 light chain 3 (LC3) and autophagic level. Furthermore, an autophagy activation model was constructed by cell starvation, the protein expression of p62 and autophagy level were detected by using Western blot assay and GFP-mCherry-LC3 plasmid transfection, and the effect of autophagy activation on the sensitivity of Huh7-LR cells to lenvatinib was detected by flow cytometry. RESULTS Compared with parental cells, the drug resistance index of Huh7-LR cells was 6.2; protein expression of p62 was increased significantly, while apoptotic rate, protein expression of Beclin-1 and LC3Ⅱ/ LC3Ⅰ ratio were all reduced significantly (P<0.05 or P<0.01); the level of autophagy was decreased to some extent. Autophagy activation could significantly increase the protein expression of p62 in Huh7-LR cells (P<0.05) and autophagy level, and significantly increase its apoptotic rate (P<0.05). CONCLUSIONS Autophagy is involved in lenvatinib resistance, and activating autophagy can reverse the resistance of liver cancer cells to lenvatinib to some extent.

Abstract: Objective To identify and analyze the phospholipase A (PLA) gene family in Talaromyces marneffei (T. marneffei), providing the basis for further research on the potential pathogenic effect and mechanism of T. marneffei PLA. Methods The members of the PLA gene family in T. marneffei were genome-wide identified by using bioinformatics, and their gene structure, chromosome distribution, protein physicochemical property and structure, conserved motif, as well as phyletic evolution, were analyzed. The expression levels of PLA genes in T. marneffei under macrophage treatment were analyzed using the qRT-PCR method. Results A total of eight PLA genes were identified from the genome of T. marneffei, unevenly located on 5 chromosomes without any tandem duplications or fragment duplications. The amino acid residues of PLA proteins ranged from 577 to 1546, molecular weights from 65 120 to 170 690, and the isoelectric point from 4.47 to 9.28. All PLA proteins were hydrophilic, with all but PLA3 classified as unstable hydrophilic proteins. Phylogenetic analysis revealed that PLA was divided into two subfamilies: PLA2 and patatin-like phospholipase, consisting of 3 and 5 members respectively. Within the same subfamily, gene structures, protein-conserved motifs, and protein structures were relatively similar, whereas significant differences existed between different subfamilies. qRT PCR results showed that the expression levels of PLA3, PLA6, and PLA8 were upregulated in T. marneffei infected with mouse macrophages. Conclusions PLA3, PLA6, and PLA8 may be related to the survival and reproduction of T. marneffei in macrophages.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Abstract: Objective To clarify the long-term evolution of hepatitis B virus (HBV) quasi-species in HBsAg asymptomatic carriers in Long'an county, Guangxi. Methods ELISA was used to detect serological markers of HBV. Viral loads were measured by real time PCR. HBV DNA was extracted from serum by kits. The whole HBV genome was amplified using nested PCR and amplicons were sequenced by next-generation sequencing (NGS). These sequences from NGS were analyzed by the software like Mega. Results Serum samples were collected from 9 HBsAg asymptomatic carriers in Longan County,Guangxi at 4 different time points in 2004, 2007, 2013, 2019 or 2020. A total of 23 serum samples and 309 full-length gene quasi-species sequences were obtained, with an average amount of (0.18±0.07) G sequencing data for each sample. Genotype of 55.54%(5/9) the studied subjects underwent genotype conversion during the long-term evolution process of HBV
quasi-species, and the genotyping results of the phylogenetic tree in the PreS/S region are in perfect agreement with the results of the whole genome analysis; recombinant B/C, I/C were found; the Sn ranged from 0 to 0.37 and the genetic diversity ranged from 0 to 0.11, respectively. A total of 21 special single nucleotide/amino acid mutations (7 in the S region, 2 in the X region, 3 in the PreC region and 9 in the BCP region) and 6 deletion mutations were detected, multiple mutations were found and no drug resistant mutations were found; 77.8%(7/9) of the HBV strains carried by the subjects in 2004 had double mutations at nt1 762(A→T) and 1 764(G→A) and a stop mutation at nt1 896(G→A); HBV mutations can be restored from the mutant type to the wild type and (or) vice versa without antiviral drug pressure, and The evolution rate of HBV genome was 2.03×10-5~3.50×10-3.Conclusion HBV genotype, recombinants, genetic complexity and diversity of HBV quasi-species can change over time during in natural infection. The transformation between HBV mutation type and wild type reduces the value of predicting clinical outcomes by genetic types and related mutations to some extent. The HBV genome evolution rate of asymptomatic carriers of HBsAg in Long'an County is very high.

【Objective】 To investigate the feasibility of laparoscopic simple prostatectomy (LSP) in the treatment of large volume benign prostate hyperplasia (BPH). 【Methods】 Clinical and follow-up data of 30 patients with large volume BPH treated with LSP in our hospital during Feb.2019 and Dec.2021 were retrospectively analyzed. All patients underwent extraperitoneal LSP operation. The perioperative and 1-12 month postoperative follow-up data were analyzed. 【Results】 The average prostate volume was (92.4±38.9) mL, operation time (125±45) min, and weight of resected prostate (60.25±16.90) g. The hemoglobin decreased by (12.21±7.25) g/d after operation. No blood transfusion was needed. There was no need for bladder irrigation after operation in 21 cases (70%), and 9 cases (30%) had bladder irrigation time of (0.95±0.49) d. The postoperative catheter indwelling time was (6.92±2.51) d, and hospital stay (5.36±1.63) d. During the follow-up of (9.25±5.4) months, there was 1 case of postoperative intestinal obstruction (Clavien-Dindo grade II), 1 case of transient urinary incontinence (Clavien-Dindo grade I), and 1 case of delayed hematuria (Clavien-Dindo grade I). No urethral stricture occurred. The maximum urinary flow rate (Qmax), post-void residual urine volume (PVR), International Prostate Symptom Score (IPSS) and quality of life (QoL) 3 months after operation were significantly improved compared with those before operation (P<0.05). There was no significant difference in sexual function before and after operation (P>0.05). 【Conclusion】 LSP is safe and effective in the treatment of large volume BPH. It has advantages of complete resection of glands, minor bleeding and short postoperative bladder irrigation time. However, it still needs to be confirmed by a prospective control study of large samples.
